Description

Technical Field

[0001] This utility model belongs to the field of hydrogen energy membrane electrode (MEA) product manufacturing, specifically a hydrogen energy micron-level thin film coating transfer and flattening mechanism. Background Technology

[0002] Currently, for CCM (Cellular Membrane Electrode) transfer, after the anode and cathode coatings are transferred to the CCM film material using a thermal transfer roller, the uncoated film is immediately rolled up, exposing only the micron-sized CCM film. At this point, the CCM has an anode coating on top and a cathode coating on the bottom. This film is only a few microns thick, extremely thin, and easily wrinkles under slight stress or environmental temperature and humidity. However, these wrinkled areas must be discarded, resulting in significant material waste in subsequent production.

[0003] As can be seen from the above, after the existing equipment rewinds the waste film from the transfer process, the CCM film is directly exposed and enters the next protective film coating process. However, due to the influence of ambient temperature, humidity and traction, the CCM film will intermittently wrinkle, resulting in many defective products and material waste. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a hydrogen energy micron-level thin film coating transfer and flattening mechanism. This mechanism can solve the problem of film wrinkling after CCM transfer, eliminating material waste and significant economic losses caused by wrinkles and defective products.

[0005] To achieve the above objectives, a hydrogen energy micron-level thin film coating transfer and flattening mechanism is designed, including a transfer mechanism A, an anode and cathode waste film winding mechanism B, a coating mechanism C, and a CCM flattening mechanism 15. The transfer mechanism A includes a transfer steel roller 2, a heat transfer roller 4, and a cylinder 5. The transfer steel roller 2 is mounted on a mounting base plate 3 and is used in pairs with the heat transfer roller 4. The heat transfer roller 4 is connected to the cylinder 5 and moves up and down under the drive of the cylinder 5. The anode and cathode waste film winding mechanism B includes a cathode waste film winding shaft 1 and an anode waste film winding shaft 6. The cathode waste film winding shaft 1 is used to collect the cathode waste film that has been transferred, and the anode waste film winding shaft 6 is used to collect the anode waste film that has been transferred. The coating mechanism C includes a cylinder 8. The system comprises a bottom protective film placement shaft 10, a coating roller 12, and a coating steel roller 13. The bottom protective film is wound on the bottom protective film placement shaft 10. The coating roller 12 is used to coat the bottom protective film on the bottom protective film placement shaft 10 onto the upper surface of the CCM film. The coating roller 12 is connected to a cylinder 8 and moves up and down under the drive of the cylinder 8. The coating steel roller 13 is fixed on the mounting base plate 3 and is used in combination with the coating roller 12 to follow the rotation. The CCM flattening mechanism 15 is set between the coating mechanism C and the anode and cathode waste film winding mechanism B. The CCM flattening mechanism 15 is used to adjust the height of the CCM film and the wrap angle between the CCM film and the coating steel roller 13. The CCM film is completely flattened by the CCM flattening mechanism 15, thereby eliminating wrinkles.

[0006] Furthermore, the CCM flattening mechanism 15 includes an up-and-down adjustment handwheel 30, a flattening roller 31, a first-round adjustment mounting block 32, and a hanging plate 33. The first-round adjustment mounting blocks 32 are symmetrically arranged on the left and right sides and are respectively mounted on the hanging plate 33. The hanging plate 33 is mounted on the mounting base plate 3. The flattening roller 31 is installed between the two first-round adjustment mounting blocks 32. The up-and-down adjustment handwheel 30 is installed on the first-round adjustment mounting block 32. The up-and-down adjustment handwheel 30 is used to adjust the height and level of the flattening roller 31, thereby adjusting the wrap angle between the CCM film 20 and the coating steel roller 13.

[0007] Furthermore, the flattening roller 31 has an arc-shaped roller surface and a structure that is thin at both ends and thick in the middle. When the CCM film 20 passes through the flattening roller 31, the flattening roller 31 flattens the wrinkled and curled CCM film 20, thereby solving the problem of wrinkles on the CCM film 20 covered by the protective film 22.

[0008] Furthermore, it also includes a cathode and anode film peeling mechanism 16. The cathode and anode film peeling mechanism 16 is symmetrically arranged in two sets. Each set of cathode and anode film peeling mechanism 16 includes a telescopic cylinder 26, a peeling pressure roller 27, left and right mounting seats 28, and a mounting fixing plate 29. The mounting fixing plate 29 is mounted on the mounting base plate 3. The telescopic cylinder 26 is installed at the left and right ends of the mounting fixing plate 29, and the left and right mounting seats 28 are respectively installed at the telescopic ends of the telescopic cylinder 26. The peeling pressure roller 27 is installed between the left and right mounting seats 28. The peeling pressure roller 27 moves telescopically under the drive of the telescopic cylinder 26. The design of this cathode and anode film peeling mechanism allows the cathode and anode waste films to be peeled off by rolling friction, which further improves the working efficiency.

[0009] Furthermore, one end of the transfer steel roller 2 is connected to a servo motor 1, and rotates under the drive of the servo motor 1. The heat transfer roller 4 is electrically heated and temperature controlled by a resistance wire, and is equipped with a pressure detector. The pressure detector is used to detect the pressing force between the heat transfer roller 4 and the transfer steel roller 2. One end of the heat transfer roller 4 is connected to a servo motor 2, and rotates under the drive of the servo motor 2.

[0010] Furthermore, an anode winding diameter detection sensor 7 and a bottom protective film placement shaft 10 are respectively provided at the anode waste film winding shaft 6 and the bottom protective film placement shaft 10. The anode winding diameter detection sensor 7 is used to detect whether the diameter of the anode waste film on the anode waste film winding shaft 6 reaches a preset value, and the bottom protective film diameter detection sensor 9 is used to detect whether the diameter of the bottom protective film 22 on the bottom protective film placement shaft 10 reaches a preset diameter. Thus, the equipment stops after the diameter reaches the preset value, reminding the user to remove the waste roll.

[0011] Furthermore, it also includes transition roller 11, transition roller 2 14, transition roller 3 17 and transition roller 4 18. Transition roller 11 is used for film transition on the bottom protective film placement shaft 10. Transition roller 2 14 and transition roller 3 17 are used for transitioning waste film on the anode waste film winding shaft 6 and cathode waste film winding shaft 1, respectively. Transition roller 4 18 is used for transitioning film after the transfer of anode and cathode films and CCM film.

[0012] Compared with existing technologies, this invention adds an arc-shaped flattening roller and an adjustable lifting mechanism before the next layer of protective film. This allows for control over the unfolding of the CCM film and the wrap angle between the film and the roller, ensuring complete flattening of the CCM film. This eliminates wrinkles and defective products, preventing material waste and significant economic losses, and solves the problem of film wrinkling after CCM transfer. The CCM flattening mechanism is equipped with a flattening roller and adjustable handwheels for height and level. The wrap angle between the CCM film and the coating roller can be adjusted, allowing the film to be flattened through the rounded wrap angle. The flattening roller is designed with an arc shape, tapering at both ends and thickening in the middle. As the CCM film passes through this roller, wrinkles and curls are flattened, effectively solving the problem of wrinkles in the protective film. Furthermore, this invention includes a cathode and anode film peeling mechanism with a symmetrical design, allowing for the peeling of waste cathode and anode films through rolling friction, further improving work efficiency.

[0025] This utility model belongs to the field of hydrogen energy membrane electrode (MEA) product manufacturing, and relates to a coating heat transfer printing device, also called a three-in-one transfer machine or CCM transfer machine. Its principle is that an anode coating is adhered to one film, and a cathode coating is adhered to another film. After transfer by this device, the anode and cathode coating layers are transferred onto a micron-sized CCM film material, respectively adhered to both sides of the CCM micron-sized film. To solve the problem of film wrinkling after CCM transfer, this utility model adds an arc-shaped flattening roller and an adjustable lifting mechanism before the next layer of protective film. This controls the unfolding of the CCM film to both sides and the wrap angle between the film and the roller, completely flattening the CCM film, thereby eliminating wrinkles and the material waste and significant economic losses caused by defective products.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0031] Mounting base plate 3: This plate is installed vertically, and all components are installed horizontally on this plate.

[0032] Heat transfer roller 4: This roller is a heat transfer roller. It is electrically heated and temperature controlled by resistance wire so that the surface of the roller can reach the required set temperature. At the same time, it can move up and down under the drive of cylinder 5. Cylinder 5 can be a pneumatic cylinder or an electric cylinder. Pressure detection can be added to detect the pressing force between the heat transfer roller 4 and the transfer steel roller 2. One end of the roller is connected to a servo motor. Under the drive of the servo motor, the roller can rotate. As long as the rising and falling is controlled, the rotation can be operated.

After being transferred by the transfer steel roller 2 and the heat transfer roller 4, the coating on the cathode strip coated film 19 and the coating on the anode strip coated film 20 are transferred onto the CCM film 20.

[0049] Anode coated film 21: The film has a cathode paste coating, with the coating side facing the CCM film side.

[0050] Bottom support protective film 22: This film is used to protect the anode surface of CCM film 20, and can also withstand a certain amount of traction to drive CCM film 20 to be wound up.

[0054] As attached Figure 4 The diagram shows the exploded view of the anode and cathode film peeling mechanism 16 of this invention. This mechanism consists of a peeling roller 27, left and right mounting seats 28, a telescopic cylinder 26, and a mounting plate 29. The anode and cathode film peeling mechanism 16 is symmetrically designed to peel off the waste anode and cathode films through rolling friction. Specifically, the telescopic cylinder 26 is mounted on the left and right mounting seats 28, driving the peeling roller 27 to extend and retract; the peeling roller 27 is mounted on the left and right mounting seats 28 and extends and retracts under the influence of the telescopic cylinder 26; the left and right mounting seats 28 are used to mount the peeling roller 27; the mounting plate 29 is mounted on the mounting base plate 3 and serves to connect and mount the telescopic cylinder 26.

This flattening structure is the core part of flattening the CCM film 20. This mechanism is equipped with flattening rollers 31 with up-and-down adjustment handwheels 30 on the left and right sides. The height and level can be adjusted on the left and right sides respectively, thereby adjusting the wrap angle between the CCM film 20 and the coating steel roller 13. This allows the CCM film 20 to be flattened in the first step by passing through the rounded wrap angle. The flattening roller 31 is designed with an arc shape, thin at both ends and thick in the middle. When the CCM film 20 passes through this roller, the wrinkled and curled CCM film 20 is flattened, thus effectively solving the problem of wrinkles on the CCM film 20 covered with the bottom protective film 22. Specifically, the up-and-down adjustment handwheel 30 can adjust the height and level of the flattening roller 31; the flattening roller 31 has a structure design that is large in the middle and small at both ends, and can straighten and flatten the CCM film 20; there are two first wheel adjustment mounting blocks 32 on the left and right sides, which are used to install the up-and-down adjustment handwheel 30. These mounting blocks are installed on the hanging plate 33; the hanging plate 33 is installed on the mounting base plate 3 and serves as a transfer.

[0056] The working principle of this utility model is as follows: the equipment is powered on → the operator threades four types of film materials, namely cathode coated film 19, CCM film 20, anode coated film 21, and bottom protective film 22, onto the belt → the equipment is designed with various parameters such as transfer length, transfer temperature, transfer pressure, and traction force → the equipment is started and running → cylinders one and two are activated to press all the film materials and start the transfer → the coating on the anode coated film 21 and cathode coated film 19 is transferred onto the CCM film 20 → the finished CCM film 20 is wound up.
