Description

Technical Field

[0001] The utility model relates to the technical field of battery processing, in particular to a solid oxide fuel cell stack pressurizing device. Background Art

[0002] The solid oxide fuel cell stack pressurizing device, also known as the solid oxide fuel cell stack extruder, is a mechanical device used to stack multiple oxide fuel cells together. This machine is usually used in fuel cell factories to facilitate the assembly and installation of fuel cell stacks. It is mainly composed of an operating table, an electric push rod, an extrusion plate, a support seat and a controller. During use, the individual batteries that need to be extruded and pressurized are placed inside the extrusion plate and the support seat, and then the electric push rod is controlled to start and drive the extrusion plate to cooperate with the support seat to extrude and pressurize the individual batteries to form a high-power density fuel cell stack. Subsequently, personnel will put a steel belt on the outside of the pressurized battery stack to stabilize the battery stack after pressurization. Since the size of the battery stack will vary with the production model and batch, if the size of the extrusion plate and the support seat is significantly different from the size of the pressurized battery, it is easy for the battery to be extruded unevenly or even deformed. Therefore, it is necessary to adjust the extrusion force range of the extrusion plate.

[0003] In the related art, during the use of the pressurizing device, the staff generally disassembles and replaces the extrusion plate and the support seat according to the actual size of the battery, so that the pressurizing range of the extrusion plate and the support seat meets the pressurizing requirements of the battery for use.

[0004] However, during the current use of the pressurizing device, due to the disassembly and replacement method, the replacement connection is mainly completed through multiple bolts. During the application operation, the general staff repeatedly turns multiple bolts to disassemble and replace the extrusion plate and the support seat, resulting in the adjustment of the force and pressure range of the extrusion plate and the support seat being more cumbersome, affecting the adaptability and flexibility of the pressurizing device in using pressurization.

After the lifting of the lifting device 11, the lifting device 11 is lifted up and the lifting of the lifting device 11 is lifted, and the lifting of the lifting device 11 is lifted.

[0033] Reference Figure 2In a preferred embodiment, a sliding opening 15 located at the bottom of the support seat 4 is opened on both sides of the top of the translation seat 12, and a sliding seat 16 is movably connected to the right side of the sliding opening 15. The top of the sliding seat 16 is fixedly connected to the bottom of the support seat 4. When the translation seat 12 is used in conjunction with the support seat 4, the translation seat 12 and the support seat 4 can be slidably connected to each other, avoiding the situation where the support seat 4 is separated from the translation seat 12 when in use. Therefore, the connection effect between the support seat 4 and the translation seat 12 is improved, and the top of the inner wall of the translation groove 13 is movably connected It is connected to a positioning column 17, the top of the positioning column 17 passes through the top of the translation seat 12, and a positioning groove 18 is provided on the top of the translation frame 14. There are several positioning grooves 18, and the positioning grooves 18 are evenly distributed. The bottom of the positioning column 17 is located inside the positioning groove 18. When the translation frame 14 is used in conjunction with the translation seat 12, it can provide the user with a medium for translation positioning between the translation seat 12 and the translation frame 14, thereby avoiding the difficulty in positioning the translation seat 12 when in use, thereby improving the convenience of translation positioning of the translation seat 12.

[0034] Reference Figure 2 In a preferred embodiment, a movable opening 19 is opened on both sides of the right side of the support seat 4, and a movable frame 20 is movably connected inside the movable opening 19.

[0036] Specifically, the working process or working principle of the solid oxide fuel cell stack pressurizing device is as follows: when in use, first, according to the actual combined pressurizing width of the external battery, the handheld translation frame 14 drives the positioning column 17 to move upward to disengage from the positioning groove 18. At this time, the magnetic sheet 22 on the top of the translation frame 14 moves with the translation frame 14 and contacts the magnetic sheet 21, and the upward-moving translation frame 14 and the positioning column 17 are magnetically positioned. Then, the handheld translation seat 12 drives the support seat 4 to move to the left, and performs a preliminary adjustment operation on the spacing distance between the support seat 4 and the push plate 3. At this time, the translation frame 14 moves inside the translation slot 13 to perform translation connection work between the translation seat 12 and the operating table 1. When the position translation of the translation seat 12 is completed, the handheld translation frame 14 drives the positioning column 17 to move downward into the positioning slot 18 to perform positioning work between the translation seat 12 and the translation frame 14. When the handheld screw 25 rotates to match the screw hole 24 and the fixing plate 23, a translation thrust is applied to the support seat 4 to fine-tune the position of the support seat 4. At this time, the rotating frame 27 follows the screw 25 to move inside the rotating cavity 26 to connect the screw 25 with the support seat 4. The lifting plate 6 is connected to the lifting plate 4 by the lifting frame 12, and the lifting plate 6 is connected to the lifting plate 4 by the lifting frame 12. The pressurizing range of the seat 4 meets the pressurizing requirements of the battery size. At this time, the stabilizing seat 7 contacts the height-adjusting plate 6 after moving upward, preparing for the subsequent force-adjusting plate 6 to be stabilized. At the same time, the connecting rod 9 follows the height-adjusting plate 6 to move inside the connecting groove 8, and performs the upward connection work between the height-adjusting plate 6 and the height-adjusting groove 5, and magnetically positions the height-adjusting plate 6 after moving upward through the magnetic block 10 and the magnetic strip 11. Then, the controller on the top front side of the operating table 1 can be used to start the electric push rod 2 to drive the push plate 3 to pressurize the battery located inside the push plate 3 and the support seat 4.
