Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to an automatic packaging device for proton exchange membranes. Background Technology

[0002] Proton exchange membrane fuel cells (PEMFCs) offer advantages such as high energy conversion efficiency, zero emissions, low operating noise, high reliability, easy maintenance, high power generation efficiency, and minimal impact from load variations. The proton exchange membrane (PEM) is the core component of a PEMFC and plays a crucial role in its performance. It not only acts as a barrier but also conducts protons. During the production of the PEM, an encapsulation device is required to encapsulate it.

[0003] Chinese Patent CN220253287U discloses an automatic proton exchange membrane packaging device, comprising: a worktable and a retrieving component disposed on the top of the worktable, and a reciprocating pressing component disposed on the top of the worktable; the retrieving component includes: a retrieving disk disposed on the top of the worktable via a rotating shaft, a grooved wheel disposed on the side of the rotating shaft, and a rotating rod disposed on the inner side of the worktable. After the proton exchange membrane to be packaged is placed inside several packaging frames, the retrieving component rotates the packaging frame to below the hot press plate. The grooved wheel enables intermittent rotation and retrieval. During the rotation and retrieval of the next packaging frame, the reciprocating screw drives the hot press plate to move up and down. When it corresponds to the inside of the packaging frame, the hot press packaging process of the proton exchange membrane is completed. This allows for continuous packaging without manual intervention to repeatedly stop and start the equipment, thus achieving a high degree of automation and improving efficiency during use.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the existing automatic proton exchange membrane packaging device cannot directly cool down the finished product after packaging, which makes the membrane temperature too high and easy to stick to the hot plate. At the same time, it is necessary to move it to the cooling station for cooling, which affects the packaging efficiency. Furthermore, during the packaging process, staff need to load and unload materials throughout the process, which increases the consumption of human resources. Utility Model Content

[0023] Compared with the prior art, the present invention has the following beneficial technical effects:

[0024] 1. By setting up an intermittent rotation mechanism, the robotic arm places the membrane electrode and gas diffusion layer into the encapsulation frame in sequence. The retrieval disk adsorbs the materials. When the motor starts, it drives the retrieval disk to rotate intermittently. This can avoid the offset or tilt caused by manual operation, ensure uniform contact between the proton exchange membrane and the electrode layer, reduce contact resistance, and improve battery performance. The intermittent rotation allows each encapsulation frame to stay under the hot press plate for a sufficient time, so that the membrane electrode and the gas diffusion layer can be fully bonded under high temperature and high pressure.

[0025] 2. Through the setting of the encapsulation cooling mechanism, the cylinder drives the temperature control box and heat transfer plate to move, and the motor drives the two stirring plates to rotate synchronously, thereby quickly stirring and mixing the internal hot air or coolant. During hot pressing, the heater starts to generate heat and performs hot pressing through the heat transfer plate. During cooling, coolant is transported through the delivery pipe to cool the finished product. In this way, the temperature of the contact surface between the finished product and the hot pressing plate can be reduced from the encapsulation temperature to the safe operating temperature in a short time, significantly shortening the cooling time. The stirring of the stirring plates can make the cooling effect more uniform and enhance the cooling effect. The rack drives the winding shaft to rotate so that the delivery pipe always follows the temperature control box to extend or shorten, so that it will not be too long and cause tangling, nor too short and cause the pipe to be taut and damaged.

[0039] Example 2

[0040] like Figures 4-5 As shown, this utility model proposes an automatic proton exchange membrane packaging device. Compared with Embodiment 1, this embodiment details the structure of the packaging and cooling mechanism.

[0041] The encapsulation cooling mechanism includes a cylinder 701, a push rod 702, a liquid storage tank 710, and a temperature control component. The cylinder 701 is located on the top of the top plate 3, the push rod 702 is located at the output end of the cylinder 701, and the liquid storage tank 710 is located on the top of the top plate 3 and on the side of the cylinder 701. The liquid storage tank 710 is used to store coolant and integrates a water pump. The output end of the water pump is connected to the top of the delivery pipe 709 for delivering and extracting coolant into the temperature control chamber 703. The temperature control component is located at the bottom of the push rod 702 and is used to control the temperature inside the chamber to perform different treatments on the proton exchange membrane. The temperature control assembly includes a rack 705, a spur gear 706, a winding shaft 707, and a fixing plate 708. The rack 705 is located on the top of the temperature control chamber 703 and is slidably connected to the inner side of the top plate 3. The spur gear 706 meshes with the side of the rack 705. The winding shaft 707 is located at the axis of the spur gear 706. The fixing plate 708 is located at the end of the winding shaft 707, and the top of the fixing plate 708 is connected to the bottom of the top plate 3. An infusion tube 709... The infusion tube 709 is wound and unwound on the take-up shaft 707. A fixing frame 712 is provided on the outside of the temperature control box 703. A second motor 711 is provided on the inside of the fixing frame 712. A third rotating shaft 713 is provided at the output end of the second motor 711. A stirring plate 717 is provided on the outside of the third rotating shaft 713. A first synchronous pulley 714 is provided at a point on the third rotating shaft 713 near the second motor 711. A synchronous belt 715 is provided on the outside of the first synchronous pulley 714. Synchronous pulley 716 is located at the end of synchronous pulley 715 furthest from synchronous pulley 714. A rotating shaft 713 and a stirring plate 717 are also located at the axis of synchronous pulley 716. When cylinder 701 is activated, it moves push rod 702, which in turn moves temperature control box 703. The movement of temperature control box 703 moves rack 705, which in turn moves rack 705 via spur gear 706 to rotate winding shaft 707. The rotation of winding shaft 707 then rotates infusion tubing 709. The infusion tube 709 is wound and unwound, so that it always moves with the temperature control box 703. It is neither too long and tangled, nor too short and taut and damaged. The starting motor 711 drives the rotating shaft 713 to rotate. The rotating shaft 713 drives the synchronous pulley 714 to rotate. The synchronous pulley 714 drives the synchronous pulley 716 to rotate through the synchronous belt 715. Thus, the two rotating shafts 713 rotate synchronously, thereby rapidly stirring and mixing the internal hot air or coolant.

[0042] In summary, when this utility model is used, the robotic arm 5 uses the suction cup 6 to pick up the membrane electrode and the gas exchange layer respectively and accurately position them within the encapsulation frame 406. The retrieval disk 401 adsorbs the materials through the adsorption hole 414. Then, the first motor 405, the second motor 711, and the cylinder 701 are started. The first motor 405 drives the first rotating shaft 411 to rotate, the first rotating shaft 411 drives the second spur gear 407 to rotate, and the rotation of the second spur gear 407 drives the first spur gear 410 to rotate. The first spur gear 410 drives the power rod 403 to rotate via the second rotating shaft 409. The power rod 403 drives the actuating block 404 to rotate. When the actuating block 404 rotates onto the intermittent rotating ring, it can cut into the slide rail, thereby driving the intermittent rotating ring to rotate. The intermittent rotating ring drives the adjusting disk 401 to rotate intermittently. When the encapsulation frame 406 with the proton exchange membrane installed rotates to below the heat transfer plate 704, the cylinder 701 drives the push rod 702 to descend. The push rod 702 drives the temperature control box 703 to move down. When the temperature control box 703 moves, it drives the rack 705 to move. The rack 705 drives the winding shaft 707 to rotate through the third spur gear 706. When the winding shaft 707 rotates, it drives the infusion tube 709 to be released, so that the infusion tube 709 always moves with the temperature control box 703. During this process, the heater 718 heats the heat transfer plate 704. At the same time, the second motor 711 drives the third rotating shaft 713 to rotate. The third rotating shaft 713 drives the first synchronous wheel 714 to rotate. The first synchronous wheel 714 drives the second synchronous wheel 716 to rotate through the synchronous belt 715, so that the two rotating shafts 713 rotate synchronously and quickly stir and mix the hot gas. After the heat transfer plate 704 reaches the preset temperature, it is pressed on the proton exchange membrane for hot pressing. After completion, coolant is introduced into the infusion tube 709. The stirring plate 717 continues to stir the coolant, thereby cooling the finished product. After cooling is completed, the coolant is withdrawn again, and the retrieval plate 401 rotates again for subsequent packaging.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
