[0026] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0027] Reference Figures 1 to 4As shown, a rolling jig is provided, including an adsorption platform 1 and a roller 21. Side plates 23 are respectively provided on both sides of the adsorption platform 1. The side plates 23 can move back and forth along the side walls of the adsorption platform 1. The roller 21 is arranged above the adsorption platform 1. A slider 24 is arranged in the side plates 23. The slider 24 can be lifted and lowered in the side plates 23. Both ends of the roller 21 are rotatably connected to the slider 24 respectively. An eccentric wheel 22 is also provided in the side plates 23. The eccentric wheel 22 is rotatably arranged above the slider 24 to control the up and down movement of the slider 24.

[0028] In this embodiment, the roller 21 is lifted, and the five-layer membrane electrode is placed on the adsorption platform 1. The adsorption is started to adsorb and flatten the material to prevent the material from moving during the rolling process. The eccentric wheel 22 is then rotated to press it together with the slider 24, driving the roller 21 to be pressed down, and the side plate 23 is pushed to make the roller 21 roll back and forth, so that the product on the adsorption platform 1 is rolled flat. Finally, the eccentric wheel 22 is rotated to release the tightening relationship and lift the roller 21, turn off the adsorption, and remove the material. This rolling fixture is simple and convenient to operate and can be applied to products of different sizes.

[0029] In one embodiment of the utility model, a pressure rod 25 is arranged above the roller 21, and the two ends of the pressure rod 25 pass through the eccentric wheel 22 and are respectively connected to the two side vertical plates 23, and the side vertical plates 23 are provided with a cross groove 231. Both ends of the pressure rod 25 are sleeved with a clamping sleeve 251 adapted to the cross groove 231, and the clamping sleeve 251 can be movably inserted into the cross groove 231. The pressure rod 25 is connected to the first handle 252 through the clamping sleeve 251. The first handle 252 is arranged on one side of the side vertical plate 23 away from the roller 21. On the side, pull out the first handle 252 and rotate it to lift the roller 21, then push the first handle 252 inward to make the sleeve 251 clamp the cross groove 231, fix the roller 21, place the five-layer membrane electrode on the adsorption platform 1, turn on the vacuum to adsorb the material flat; pull out the first handle 252 and rotate it, press the roller 21 downward, then push the first handle 252 inward to make the sleeve 251 clamp the cross groove 231, push the side plate 23 to make the roller 21 roll back and forth, and roll the product on the adsorption platform 1 flat.

[0030] Preferably, a plurality of blocks 2511 are provided on the ferrule 251, and the plurality of blocks 2511 are evenly distributed on the outer periphery of the ferrule 251 and are in a cross-shaped structure. The blocks 2511 are engaged with the cross groove 231, and the blocks 2511 are inserted into the grooves of the cross groove 231 to fix the pressure rod 25, thereby preventing the roller 21 from rolling with insufficient rolling force, causing the product to be rolled unevenly.

[0031] In one embodiment of the utility model, the eccentric wheel 22 is connected to the slider 24 through two connecting parts 3. When the first handle 252 is pulled out to rotate the pressure rod 25, the connecting part 3 is driven to rotate, thereby driving the slider 24 to move up and down. The roller 21 can be lifted to place the material on the adsorption platform 1, or the roller 21 can be rotated to press down the eccentric wheel 22 to press the slider 24, allowing the roller 21 to roll the material.

[0032] In one embodiment of the utility model, two cylinders 241 are provided on both sides of the top of the slider 24, and elastic parts are provided on the cylinders 241 to play a buffering role to prevent the product from being crushed due to excessive downward pressure. A U-shaped block 26 is provided in the side plate 23, and the opening of the U-shaped block 26 faces downward. The U-shaped block 26 is arranged above the slider 24, and a circular hole 261 is provided on the U-shaped block 26 to match the cylinder 241. The cylinder 241 is inserted into the circular hole 261. A bolt 27 is provided on the top of the U-shaped block 26, and one end of the bolt 27 passes through the top plane of the side plate 23 and presses the U-shaped block 26. The other end of the bolt 27 is exposed on the top plane of the side plate 23. Turning the bolt 27 to press downward will cause the U-shaped block 26 to compress the elastic part downward. The pressure of the bolt 27 on the U-shaped block 26 is adjusted according to actual conditions.

[0033] In one embodiment of the present invention, a second handle 28 is provided on a side of the side stand 23 away from the roller 21 to facilitate pushing the side stand 23 .

[0034] In one embodiment of the utility model, a hollow space 11 is provided at the bottom of the adsorption platform 1, and two round rods 12 are provided in the hollow space 11. The two round rods 12 can move back and forth in the hollow space 11, and the two ends of the two round rods 12 are respectively fixedly connected to the bottom of the two side vertical plates 23. The two round rods 12 realize the forward and backward movement of the side vertical plates 23, thereby driving the roller 21 to roll forward and backward.

[0035] Furthermore, a plurality of vacuum holes 13 are provided on the adsorption platform 1, and the plurality of vacuum holes 13 are evenly distributed to ensure that the adsorption force on each part of the product is equal, so that wrinkles are not easily generated.

[0036] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
