[0024] The present invention controls the tension of the material film during the transfer process to ensure that the material film can control the transfer material within a reasonable tension range. The tension generated by the material film during operation is detected by a tension detection roller to detect the tension fluctuation during the operation process, and the data is transmitted to the control module. The operator can input the tension value and limit the tension fluctuation range through the control module, and control the power source through the control module to make the material film tension operate within a reasonable fluctuation range.

The present invention monitors the alignment size error information of the front and back surfaces of the membrane electrode material before transfer. During the implementation process, the proton membrane 51, the cathode transfer membrane 4, and the anode transfer membrane 52 are respectively detected by the visual detection module. At the same time, a light source is provided in the visual detection module to ensure that the material film is displayed normally without distortion under the camera illumination. After the image is collected, it is transmitted to the control module for image comparison and analysis, and the alignment position size deviation is adjusted after the data is calculated; In the present invention, the control module adjusts the lifting and lowering of the register lifting roller according to the feedback of the front and back surface alignment size error data information obtained by the visual inspection system to control the adjustment of the alignment position of the transfer film material during transfer; during the implementation process, after the film is put on and before the machine is turned on, the register lifting roller is in the middle position and then the machine is turned on for trial operation; during the operation and debugging stage, the material film tension is ensured to operate within a suitable range according to the parameters set in the control module; during the operation, the position size of the material film during alignment is obtained through the visual inspection system, and the deviation value of the position size is obtained after comparison with the reference substrate. After processing and analysis, the control module adjusts the forward and reverse rotation of the motor to realize the lifting and lowering of the register lifting roller to compensate for the deviation value of the alignment position size of the transfer material film; The present invention preheats the transfer film through a preheating device to maintain the activity and stability of the catalyst material on the transfer film, and uses the first slit coating die 18, the second axial deviation correction roller 32 and the second slit coating die 45 to level and pre-tighten the parallelism of the transfer film material, and finally performs hot extrusion transfer on the transfer film material. This process ensures that the transfer film material can be hot extruded and transferred at a suitable activity value under a constant temperature environment, and accurately realizes the positioning accuracy and dimensional control of the transfer material and the improvement of product quality. During the implementation process, the transfer film material is in a constant temperature state before the transfer, and is preheated by a preheating oven to make the transfer film material reach a certain activity temperature, and then the transfer film material is leveled and pre-tightened by an adjustment roller group 48. When the transfer film material overheats the transfer bottom roller 50, a mold temperature controller is used to control the roller surface temperature, and a heat transfer rubber roller 49 performs hot pressing on the transfer film material. At this time, the transfer of the film material is achieved, and the subsequent process performs a winding and protection treatment on the transferred film material.

[0025] The use process of the membrane electrode integrated thermal transfer device of the present invention is as follows: First press the test film as Figure 1 The material path shown is used for material threading, debugging and machine testing. The function of each module is verified through the control module. First, ensure that the working status feedback of each functional module is normal. After debugging, the anode transfer membrane 52, the cathode transfer membrane 4 and the proton membrane 51 are installed on the unwinding reel; the whole machine equipment is suspended, and the pressure rollers are turned on to press the material film and keep it still. The test film is cut on the material connection table, and the test film rolls on the unwinding reel are replaced with the anode transfer membrane 52, the cathode transfer membrane 4 and the proton membrane 51 respectively. Then, the material film is connected with tape on the material connection table. After connection, the pressure roller is returned to the initial position; The equipment is started, and each functional module is parameterized. The whole equipment runs at a low speed first, and then speeds up when it is stable. The tension fluctuation value is set to ≤±1N, the visual detection position accuracy is ≤±0.2mm, the servo motor of the transfer registration lifting roller is controlled with micron-level precision, and the surface temperature of the thermal transfer rubber roller 49 and the thermal transfer bottom roller 50 is set according to the transfer effect. The parameters are adjusted for trial operation; during the operation of the material film, the tension of the material film can be detected by the tension detection roller according to the fluctuation value of the tension of this material section, and the feedback is sent to the control module. After analysis and processing by the control module, the swing amplitude of the first swing roller 8, the second swing roller 25 and the third swing roller 36 is controlled to adjust the tension fluctuation value of this section of the material film; After the tension of the material film is stable, it enters the traction bottom roller. At this time, the slit coating die head can be used to coat the anode catalyst layer and cathode catalyst layer with equal spacing and gaps. The coating diagram is as follows Figure 2 As shown; set the horizontal and vertical spacing coating mode, the coated material film enters the tension detection roller in turn, the tension detection roller detects the tension of the material film in this section from coating to hot extrusion, and performs real-time detection and monitoring of the tension of this section of the material film; When entering the registration lifting roller, the registration lifting roller is in the middle of the initial position, and the transfer position is adjusted after waiting for the visual detection alignment error data feedback. The adjustment margin from the middle position of the registration lifting roller to the upper and lower ends is more than twice the transfer spacing. Sufficient adjustment margin must be ensured. In the registration alignment process, the transfer position is adjusted in time to reduce or even eliminate the waste of the catalyst layer on the anode transfer film 52 and the cathode transfer film 4; when passing through the axial deviation correction roller, according to the setting of the axial deviation correction roller adjustment accuracy of ±0.1mm, the axial and lateral offset errors of the material film during transfer are guaranteed to be within 0.2mm, and the waste is also reduced in the lateral alignment error; The accuracy of transfer relies on the second visual inspection module 19 and the fifth visual inspection module 46 to collect and analyze the horizontal and vertical data. After being processed by the control module, the registration lifting rollers are raised and lowered to adjust the longitudinal position of the transfer area of ​​the material film; after adjusting the horizontal and longitudinal positions, the material film enters the oven preheating module 47 for preheating, and the temperature of the preheating device is set to 60°C to maintain the reaction activity of the catalyst layer. The temperature value can be flexibly adjusted according to the transfer effect; the roller group 48 is adjusted to pre-tighten and adjust the horizontality of the material film, and then it enters the heat transfer bottom roller 50 and the heat transfer rubber roller 49 for hot extrusion transfer. The heat transfer bottom roller 50 sets the temperature parameters after the rollers are heated and kept constant, and the transfer is extruded by the heat transfer rubber roller 49. The extrusion force of the heat transfer rubber roller 49 is controlled by an electric cylinder. The pressure value is set to 15KN, and the pressure is flexibly adjusted according to the transfer effect.
