Ultralight Robot Grips Misati has many years of experience designing and manufacturing tubular robot grips for the automobile industry. These are very complex and sturdy grips, as they must withstand such tough environments as resistance or arc welding. Examples of robot grips with Misati s miniclamps at SEAT factory page 8
Ultralight Robot Grips However, there are many processes where such heavy and large grips slow down production and raise the price of the project. This is why Misati has developed the new ultralight robot grips, which are just as reliable and accurate but more productive and cheaper than tubular ones. Example of an ultralight grip used in hot stampingprocesses page 9
1. New Technopolymer Mountings & Brackets As its name suggests, the new Ultralight Robot Grips are characterized by its reduced weight. This drastic reduction in weight is possible because of our new range of mountings & brackets manufactured in technopolymer, which is a glassfibre reinforced polyamide perfect for parts subjected to severe forces, such as mountings and brackets of robot grips. MECHANICAL PROPERTIES Good elasticity under fatigue and creep Impact resistance High stiffness, toughness and compactness Good performance: static & dynamic loads and vibrations Improved dimensional stability High tensile strength. Lower wear Repeated production ENVIRONMENTAL FRIENDLY Recycable Pollution-free It consumes less energy during production than steel or aluminium page 10

New Technopolymer Mountings & Brackets PHYSICAL PROPERTIES Density = 1.56 kg/dm3 Chemical resistance to solvents, fuels, oils, etc. Electrical insulator Heat resistance (above 120 C) Flame-retardant Good mechanization ECONOMIC PROPERTIES Reduction in costs: injection Cost reduction in the production process: machining, surface finish and treatment Simple maintenance page 11
2. More Productive Grips We all know intuitively that the weight of the grip should be reduced, because it affects the productivity of the robot installation. The greater the weight (mass) to be moved by the robot, the bigger and slower the robot will be. Robot cycles will be longer and production of parts will be lower. The lighter the grip, the higher the production of the robot. page 12
2. More Productive Grips Misati s Ultralight Robot Grip weighs 55.96% less than its equivalent tubular grip, i.e., it weighs less than a half. Ultralight Grip Weight = 19,810 kg - 55.96% Tubular Grip Weight = 44,986 kg page 13
2.1. Smaller Robots Misati s Ultralight Robot Grip will contribute to increase production of your robot installation. Investment will be reduced as smaller and cheaper robots may be used. page 14
2.2. Less Risk of Collision Normally, there isno free space in tools. It is very difficult to go in the tool with a large grip, with big clamps and split mountings on. Furthermore, it takes up some free space that we cannot afford to get rid of. Therefore, there is a high risk of collision. page 15
2.2. Less Risk of Collision FREE AREAS The Ultralight Robot Grip is appropriate to work under lack of space conditions, as it is compact and resistant. It is smaller and it takes up less space than tubular grips. Its entry and exit from the tool becomes easier and safer, thus reducing the risk of collision. page 16
2.3. Less Incidents or Production Stoppages How many times has your robot installation stopped working because cables of the grip have got caught or disconnected? Have you recorded the loss? page 17
2.3. Less Incidents or Production Stoppages Misati s Ultralight Robot Grips have been designed to house all cables through the inside of mountings, brackets, tubes and profiles. Cables are protected and accessible at all times. page 18
2.3. Less Incidents or Production Stoppages The result is a tidy grip, with just the essential exposed cables to avoid them getting caught or broken. page 19
2.4. Perfect Fastening of the Part Robots can work at a very high speed. Just in one cycle, the robot can change direction several times, with the corresponding acceleration or braking. If parts are not well fastenend, whenever the robot accelerates or brakes, there may be a risk that parts slide and fly out at any time. page 20
2.4. Perfect Fastening of the Part Misati s high-force-and-smaller clamps, which have a low air consumption and cost, can better adapt to the shape and size of the sheet to fasten it safely. page 21
2.4. Perfect Fastening of the Part Vertical, horizontal and circular movements of the robot, together with acceleration and braking factors, could make the clamp lose the sheet if there is no air pressure. So, even though air is missing, parts will be safely fastened by Misati s non-reversible clamps. Detachments and loss of position of these parts are prevented. Misati s clamps are non-reversible. Once closed, they can only be opened again by injecting compressed air into it. page 22
2.4. Perfect Fastening of the Part To avoid incidents or production stoppages, it is absolutely necessary to have the part controlled at all times. This is why the ultralight grip can control the presence of the part as well as detect if the clamp is open or closed. Both sensors can be used together or separately. page 23
3. Cheaper Grips We are all interested in controlling costs of new investments. We always wish to purchase the best product at the lowest possible price and recover the cost quickly. But, how could our customers save money with Robot Grips without losing any technical features? Would it be possible to reduce the investment cost in our grips and purchase a technologically advanced product adapted to your needs? page 24
3.1. Adaptable and Recoverable Structure Some users still opt for welded grips. A priori, they may seem cheaper, but those who have already used them know how difficult and expensive it is to modify them when there is a last-minute change on the part to be fastened. Most of the time the grip needs to be entirely remade. This is why itis cheaper and safer to work with modular and standard elements, as they are flexible and recoverable. = + page 25
3.2. Savings in Engineering Hours Designing a robot grip may be very expensive and laborious because, for example, there might be no space to go in the tool, special gripper fingers should be used to fasten the part, a last-minute change on the part could alter all the structure of the grip, etc. These and other factors entail time, and so cost. page 26
3.2. Savings in Engineering Hours Modular mountings of Misati s Ultralight Robot Grip make it easier to combine elements. 1 2 3 4 SPT-30 TUBAC-30x4-LxL UPLR-28-30-T GL-20-RG-S0 SVT-30 TUBAC-30x4-LxL UCTR-28-30-T GL-20-RG1-S0 SPT-30 TUBA-30X4-L UPLR-28-30-ZT GL-20-RG-S0 SVT-30 TUBA-30X4-L UPLR-28-30-T GC-20-RG-S0 To check all possible structures, please feel free to contact us and ask for our Ultralight Robot Grips poster. page 27
3.2. Savings in Engineering Hours As we will see further on, the Ultralight Robot Grip is made up of less parts, so it will take less time to design it. Misati s catalogue has, moreover, a wide range of standard gripper fingers, which can fasten safely all kinds of parts, even at high accelerations. With Misati s Ultralight Robot Grip, it is easier to design a grip (less engineering hours). page 28
3.3. Savings in the Number of Working Hours (Assembly & Adjustment) Even though elements are modular, assembling and especially adjusting a grip may be a time-consuming work. To adjust a terminal element a miniclamp or a centring miniclamp it is sometimes necessary to move all brackets and mountings of the structure. The problem is that, when any of these mountings or brackets move, the other elements of the structure can probably lose their position. Tubular Grip page 29
3.3. Savings in the Number of Working Hours (Assembly & Adjustment) Ultralight Grip The closer the degree of freedom is to the terminal element, the more accurate and easier will be the adjustment of the grip. This is why, unlike tubular grips, degrees of freedom in Ultralight Robot Grips are very close to miniclamps. Tubular Grip page 30
3.3. Savings in the Number of Working Hours (Assembly & Adjustment) Traditional tubular grips lose their position in points 3 & 4 when screws are loosened to adjust positions 1 or 2. Ultralight Grip 1 The arm of the grip being assembled will fall swinging like a pendulum. 1 3 2 4 2 The arm of the ultraligh grip slides along the profile slots, which act as a guide. Tubular Grip Position can be adjusted without the rest of the grip losing its orientation, which becomes very useful during assembly and adjustment as it saves time. page 31
3.4. Less Number of Parts, Lower Cost 1 11 parts 1 4 parts 2 3 7 6 2 3 4 5 8 9 10 Misati s Ultralight Robot Grip is made up of less parts, which are all standard and cheaper than their equivalent in tubular grips (injected parts vs machined and split mountings) and, therefore, the total cost of the grip is lower. 4 11 Machines and Split mountings Injected parts page 32

Adjustment of a Robot Grip Apart from the assembly hours, the hours spent in the adjustment of the grip should always be added to the final cost. Adjusting a traditional tubular robot grip can last many hours, even days, as countless adjustments have to be made to get the theoretical geometry. During those hours, the robot will remain stopped without manufacturing anything. page 34
Ultralight Grips: No Adjustment Needed No adjustment is needed on Misati s Ultralight Robot Grips. Misati has a team of technicians who are expert on different areas. They will design, assemble, adjust and verify the geometry of our customer s ultralight robot grip. page 35
Saving in Time and Cost The main advantage of making a robot grip with Misati is the significant saving in time and cost for robot grips users, because Never-ending adjustments are over. Your robot installation won t stop for hours or days without manufacturing anything. Customers will save money on travelling expenses and the supplier s working hours, as the grip is delivered assembled, preadjusted and geometrically verified. A simple start-up could be made by the user of the grip himself in just one hour. page 36
Ready to Use You will receive a finished grip, which will only need a quick adjustment of just one hour before beginning to work. page 37
