Description

Technical Field

[0001] The utility model belongs to the technical field of production jigs, and more specifically relates to a jig for assisting frame film in cleaning residual materials. Background Art

[0002] The membrane electrode is the site of multiphase material transmission and electrochemical reaction in fuel cells, which determines the performance, life and cost of fuel cells. It is mainly made of catalyst, proton exchange membrane, gas diffusion layer and frame membrane. The frame membrane, also called edge sealing membrane, mainly supports the foil to keep the membrane electrode taut. At the same time, it reliably separates the media (H2, O2) from each other and can also seal the system to prevent leakage.

[0003] At present, after the frame film is rolled and cut by a roller knife, a person needs to hold the rolled frame film with one hand and use a tool with the other hand to remove the cut waste part. When removing the waste stuck on the frame film, the product is easily scratched. Because the waste is stuck on the frame film, it is difficult and cumbersome to clean up the waste, so the efficiency of cleaning the waste is low. At the same time, the waste is small and easily causes it to fly everywhere, affecting the product quality. Utility Model Content

[0023] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0024] Reference Figure 1 to Figure 2 As shown, a jig for assisting in cleaning residual materials of a frame film is provided, comprising a main body 1, a first plane 11 is provided on the top of the main body 1, a positioning block 12 protrudes outward from the middle of the first plane 11, positioning holes 13 are symmetrically provided on both sides of the main body 1, a waste box 2 for storing waste materials is detachably provided on the bottom of the main body 1, the positioning hole 13 is communicated with the waste box 2, a pressing plate 3 is provided on one side of the main body 1, the pressing plate 3 is rotatably connected to the main body 1, a plurality of pressing components 31 are provided on the pressing plate 3, and each pressing component 31 is rotatably inserted into the corresponding positioning hole 13.

[0025] In this embodiment, the membrane electrode frame membrane after rolling is placed on the first plane 11 of the main body 1, and the positioning frame in the middle position of the membrane electrode frame membrane is aligned with the positioning block 12 of the main body 1, so that the positioning block 12 fixes the membrane electrode frame membrane, and the pressing plate 3 is rotated to press the rolled part with the pressing component 31 on the pressing plate 3, and the pressed waste falls into the waste box 2 through the positioning hole 13, and is poured into the trash can after it is full.

[0026] In one embodiment of the utility model, a first chamfer 14 for marking is provided on the main body 1. The first chamfer 14 can not only mark the placement direction of the main body 1, but also when the membrane electrode frame film is taken out, if the membrane electrode frame film exceeds the position of the first chamfer 14, a part of the membrane electrode frame film can be picked up at the first chamfer 14 and the membrane electrode frame film can be gently taken out, thereby facilitating the removal of the membrane electrode frame film.

[0027] In one embodiment of the utility model, an assembly groove 15 is provided on the bottom edge of the main body 1, and the top of the waste box 2 is inserted into the assembly groove 15, so that it can be removed and replaced with a new waste box 2. At the same time, the assembly groove 15 can better fix the position of the waste box 2 to avoid displacement when cleaning the waste on the membrane electrode frame membrane, resulting in the waste being unable to fall into the waste box 2.

[0028] Furthermore, a connecting block 16 is provided at the bottom of the main body 1, the assembly groove 15 is arranged around the outer circumference of the connecting block 16, and the positioning hole 13 passes through the connecting block 16, so that the waste material can fall into the box after the waste material box 2 is installed.

[0029] Preferably, the positioning holes 13 are evenly distributed on both sides of the main body 1, and the location of the positioning holes 13 can also be designed according to the cutting position of the roller cutter.

[0030] In one embodiment of the utility model, one side of the main body 1 is connected to one side of the pressing plate 3 by a rotating shaft, preferably, such as a hinge connection. By rotating the pressing plate 3, the pressing component 31 on the pressing plate 3 presses off the waste material cut out by rolling. When placing the membrane electrode frame film, the pressing plate 3 is rotated to open. Such a cyclic operation can reduce the risk of scratching the frame film and improve the efficiency of cleaning the waste material.

[0031] In one embodiment of the utility model, the pressing assembly 31 is composed of a fixing rod 311 and a pressing ball head 312. One end of the fixing rod 311 is detachably set on the pressing plate 3, and the other end of the fixing rod 311 is detachably connected to the pressing ball head 312. The detachable fixing rod 311 and the pressing ball head 312 can be replaced separately when they need to be replaced after being damaged, which is convenient for replacement and maintenance.

[0032] Preferably, a thread is provided on the connecting end of the fixing rod 311 and the pressing plate 3, and a threaded hole is opened on the pressing plate 3, and the fixing rod 311 and the pressing plate 3 are connected by threads; the pressing ball head 312 is made of soft material to prevent scratching of the membrane electrode frame film when cleaning waste, thereby reducing the defective rate of the frame film.

[0033] At the same time, the diameter of the pressing ball head 312 is smaller than the diameter of the positioning hole 13 , so that the pressing ball head 312 can be inserted into the positioning hole 13 to press the waste into the waste box 2 .

[0034] The utility model rotates the pressing plate 3 to make the pressing ball head 312 press the rolled waste of the membrane electrode frame film fixed on the first plane 11. When the pressing ball head 312 contacts the rolled waste, it is pressed until the waste is separated from the membrane electrode frame film, so that the waste falls into the waste box 2 through the positioning hole 13. This fixture has a simple structure, can reduce the defective rate of the frame film, and improve the efficiency of cleaning the waste.

[0035] 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.
