In this way, by providing a fourth drive motor 82, the fourth drive motor 82 drives the rotation of the screw rod 83, thereby driving the track seat 84 to move on the movable track 81 through the threaded connection between the screw rod 83 and the threaded block, and then adjusting the position of the pad 85 to facilitate receiving the empty mold transferred from the transfer component 7; by providing a limit bar 86, during the mold recovery process, the limit bar 86 can realize the limitation of the mold on the pad 85, thereby improving the stability of multiple molds when stacked.

[0051] Working principle:

[0052] Before the processing begins, the operator can place the finished product model 219 in the fixed-size space according to the requirements, and adjust the position between the first gear bar 2171 and the second gear bar 2181 according to the size of the finished product model 219. After adjusting the size of the fixed-size space, the mold carrying the membrane electrode frame is placed in the fixed-size space to facilitate subsequent processing;

[0053] After the processing starts, the membrane electrode is unwound from the unwinding roller 11, and then the membrane electrode is sequentially conveyed to the processing plate 51 through multiple winding rollers 12. When the membrane electrode is ready, the operator uses the transfer device 22 to adsorb the mold in the fixed-size space onto the membrane electrode, and then driven by the membrane electrode, they simultaneously arrive at the bottom of the hot pressing component 4 to complete the hot pressing molding. After molding, the membrane electrode frame on the mold is detached, and then the empty mold is clamped by the transfer component 7 and collected to the recovery component 8 for easy reuse, thereby reducing production costs.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
