Description

[Technical field]

[0001] The invention belongs to the field of hydrogen energy membrane electrode (MEA) product production, and specifically relates to a waste-free structure design and control method for intermittent transfer catalyst. [Background Technology]

[0002] At present, for the production of membrane electrode MEA, the cathode coating and the anode coating are each adhered to a film material, and the three strips are synchronously moving forward at the same speed. After being rolled by the thermal transfer roller and the steel roller, the cathode coating and the anode coating will be adhered to the CCM proton membrane film, thereby realizing the transfer work. During the transfer process, controlling the contact time or number of rotations of the thermal transfer roller and the steel roller can control the transfer length of the anode and cathode coatings, thereby realizing the transfer process of the required length. However, the three membrane materials are currently moving forward synchronously and at the same speed, and the anode and cathode membrane materials are relatively stationary relative to the CCM proton membrane film. Therefore, after reaching the required transfer length, the thermal transfer roller needs to be lifted. After lifting, the part where the thermal transfer roller and the steel roller are not in contact will not be transferred, so that this part of the anode and cathode coatings will still adhere to their respective membranes and fail to be transferred to the CCM proton membrane material. When the next piece of the required length is transferred, the anode and cathode membrane materials have passed the thermal transfer roller, and the lifted part in the middle will cause material waste.

[0003] It can be seen that the main deficiencies are as follows:

[0004] 1. The cathode coating film material, the anode coating film material and the CCM proton membrane film are operated synchronously and at the same speed. When the thermal transfer roller and the transfer steel rod are not in contact and lifted, the cathode coating and the anode coating will cause the same length of coating waste.

[0005] 2. The cathode coating membrane material and the anode coating membrane material cannot be independently controlled to start and stop, and must run simultaneously with the CCM proton membrane film. They cannot be independently controlled from each other. [Summary of the invention]

[0006] The purpose of the present invention is to solve the above-mentioned deficiencies and provide an intermittent transfer catalyst waste-free structural design, which solves the waste problem of cathode coating and anode coating during the transfer process, achieves zero waste or very little waste of coating, and thus saves costs to the maximum extent.

The anode coating film roll 10 is connected to the anode coating servo motor and rotates under the drive of the anode coating servo motor. The cathode coating film roll 28 is connected to the cathode coating servo motor and rotates under the drive of the cathode coating servo motor.

The heat transfer roller 14 drives the anode film material 1, the cathode film material 2 and the CCM proton film 9 to move toward the steel roller 25 under the push of the cylinder 13, and then transfers the anode coating 3 on the anode film material 1 and the cathode coating 4 on the cathode film material 2 to the CCM proton film 9; the anode film material 1, the cathode film material 2 and the CCM proton film 9 are independently controlled and operated. After the heat transfer roller 14 and the steel roller 25 transfer the required length, the heat transfer roller 14 is lifted and separated from the steel roller 25. At this time, the anode film material 1, the cathode film material 2 and the CCM proton film 9 are contacted and separated. The separated anode film material 1 and the cathode film material 2 stop running, and the CCM proton film 9 moves forward alone for the required length, and then performs the transfer work of the next piece, thereby avoiding the waste of the anode coating 3 and the cathode coating 4 during the transfer process.

The CCM proton film input transition shaft 29 and the CCM proton film winding transition shaft 21 are each provided with at least two and are located in the same straight line. The CCM proton film input transition shaft 29 is used for the transition of the CCM proton film 9 input into the thermal transfer roller 14 before transfer.

[0015] Furthermore, it also includes a base plate 16, and the cylinder 13, transition roller 1 12, transition roller 4 26, transition roller 2 18, transition roller 3 24, the axis of the anode coating film roll 10, and the axis of the cathode coating film roll 28 are all installed on the base plate 16.

[0016] The present invention also provides a control method for an intermittent transfer catalyst waste-free structural design, comprising the following steps:

[0017] 1) The anode film material 1 wound on the anode coating film roll 10 is wound around the transition roller 12, the thermal transfer roller 14, the transition roller 2 18 in sequence to the anode waste film winding shaft 17, and the cathode film material 2 wound on the cathode coating film roll 28 is wound around the transition roller 4 26, the steel roller 25, the transition roller 3 24 in sequence to the cathode waste film winding shaft 22;

[0018] 2) The CCM proton membrane 9 is moved along the CCM proton membrane input transition axis 29 and the CCM proton membrane winding transition axis 21 to the CCM proton membrane winding axis 19;

[0019] 3) The design includes but is not limited to transfer length, transfer temperature, transfer pressure and traction;

[0020] 4) Start the operation, the cylinder 13 pushes the thermal transfer roller 14 to move toward the steel roller 25 to press the anode film material 1, the cathode film material 2 and the CCM proton film 9 to start the transfer, and the anode coating 3 on the anode film material 1 and the cathode coating 4 on the cathode film material 2 are transferred to the CCM proton film 9;

[0021] 5) Finally, the finished CCM proton film 9 with the anode coating 3 and the cathode coating 4 transferred is rolled up onto the CCM proton film winding shaft 19;

[0022] 6) During the transfer process, the anode film material 1, the cathode film material 2, and the CCM proton film 9 are all independently controlled and operated. When the thermal transfer roller 14 and the steel roller 25 have transferred the required length, the thermal transfer roller 14 is lifted and separated from the steel roller 25. At this time, the anode film material 1, the cathode film material 2 and the CCM proton film 9 are contacted and separated. After the separation, the operation of the anode film material 1 and the cathode film material 2 stops, and the CCM proton film 9 moves forward alone to the required length, and then the next piece of transfer is carried out, thereby avoiding the waste of the anode coating 3 and the cathode coating 4 during the transfer process.

[0023] Compared with the prior art, in order to solve the material waste of cathode coating and anode coating, the present invention suspends the CCM proton film through the thermal transfer roller and the steel roller, and the cathode coating film material and the anode coating film material form a wrap angle with the thermal transfer roller and the steel roller respectively, so that the three kinds of film materials can independently control their operation. When the thermal transfer roller and the steel roller transfer the required length, the thermal transfer roller is lifted and separated from the steel roller. At this time, the cathode coating film material and the anode coating film material are contacted and separated from the CCM proton film. After separation, the operation of the cathode coating film material and the anode coating film material stops, and the CCM proton membrane film moves forward alone for a required length, and then the next piece of transfer work is carried out. In this way, since the operation of the cathode coating film material and the anode coating film material stops, the CCM proton membrane film moves forward, so that the cathode coating film material and the anode coating material can be realized without waste. In summary, the present invention solves the waste problem of the cathode coating and the anode coating during the transfer process, realizes zero waste or very small waste of the coating, thereby saving costs to the maximum extent.

After the separation, the operation of the anode film material 1 and the cathode film material 2 stops, and the CCM proton film 9 moves forward alone to the required length, and then the next piece of transfer is carried out, thereby avoiding the waste of the anode coating 3 and the cathode coating 4 during the transfer process.

[0041] The present invention belongs to the field of hydrogen energy membrane electrode (MEA) product production, and relates to a catalyst coating thermal transfer device, also called a three-in-one transfer machine or CCM transfer machine.

When the thermal transfer roller and the steel roller transfer the required length, the thermal transfer roller is lifted and separated from the steel roller. At this time, the cathode coating film material and the anode coating film material are contacted and separated from the CCM proton film. After the separation, the operation of the cathode coating film material and the anode coating film material stops, and the CCM proton membrane film moves forward alone for a required length, and then the transfer work of the next piece is carried out.
