[0024] Reference Figures 1 to 5The present invention proposes a battery bipolar plate processing equipment, comprising: a material storage rack 1, a material pressing mechanism 2 and a positioning mechanism 3, wherein a raw material 100 is wound on the material storage rack 1; the material pressing mechanism 2 comprises a plurality of thinning components 21 and an embossing component 22, wherein the plurality of thinning components 21 are sequentially arranged at intervals along the transport direction of the raw material 100, and the embossing component 22 is arranged in parallel with the thinning component 21 on a side of the thinning component 21 away from the material storage rack 1, and the thinning component 21 and the embossing component 22 are both provided with a pressing gap for the raw material 100 to pass through; the positioning mechanism 3 is arranged on a side of the embossing component 22 close to the thinning component 21, and the positioning mechanism 3 is arranged on a side of the embossing component 22 close to the thinning component 21. The positioning mechanism 3 includes a support frame 301 and pushing members 302 symmetrically arranged on both sides of the raw material 100, the support frame 301 is rotatably connected to a conveyor belt 303, the upper end surface of the conveyor belt 303 abuts against the raw material 100, the pushing member 302 is arranged on the upper end surface of the support frame 301, and the driving end of the pushing member 302 is fixedly connected to a pushing head 304, the pushing head 304 is used to abut against the side of the raw material 100, and the pushing head 304 is provided with a guide portion 305 toward the thinning component 21, so that the raw material 100 is positioned and adjusted by the positioning mechanism 3 after being output from the thinning component 21 and enters the embossing component 22.

[0025] In the above embodiment, efficient processing of battery bipolar plates is achieved through the material storage rack 1, the material pressing mechanism 2 and the positioning mechanism 3. The material storage rack 1 serves as a temporary storage and supply device for the raw material 100, ensuring the continuous supply of the raw material 100, reducing the material replacement time and improving the production efficiency.

[0026] The material pressing mechanism 2 is composed of a plurality of thinning components 21 and an embossing component 22. The thinning components 21 are arranged in sequence along the transportation direction of the raw material 100, and the raw material 100 is gradually compressed to the required thickness by step-by-step thinning. This not only ensures the uniformity of the thickness of the bipolar plate, but also avoids material breakage or deformation caused by one-time excessive compression. The embossing component 22 presses a specific flow channel texture or pattern on the thinned raw material 100, thereby enhancing its electrochemical performance.

[0027] The positioning mechanism 3 is located on the side of the embossing component 22 close to the thinning component 21, that is, between the embossing component 22 and the last thinning component 21. Through the coordinated action of the support frame 301, the conveyor belt 303 and the pusher 302, the raw material 100 is accurately positioned and adjusted. The upper end surface of the conveyor belt 303 abuts against the raw material 100, providing stable support for the transmission of the raw material 100; the pusher 302 abuts against the side of the raw material 100 through the pusher head 304 connected to its driving end, and guides the raw material 100 to enter the embossing component 22 along a predetermined path with the help of the guide part 305. This positioning method not only ensures the stable position of the raw material 100 during the embossing process, but also improves the accuracy and consistency of the embossing.

[0028] In summary, the battery bipolar plate processing equipment realizes efficient and precise processing of the raw material 100 through its unique design of the material storage rack 1, the material pressing mechanism 2 and the positioning mechanism 3, and provides strong support for the production of battery bipolar plates.

[0029] refer to Figure 2 and Figure 3 In one embodiment, the positioning mechanism 3 also includes a snap-in plate 306, which is arranged below the driving end of the pushing member 302, and the driving end of the pushing member 302 is sleeved with an adjusting frame 307, in which a snap-in pin 308 is slidably connected, and the snap-in pin 308 passes through the adjusting frame 307 and is inserted into the snap-in plate 306, and the snap-in plate 306 is provided with a plurality of snap-in grooves 309 clamped with the snap-in pin 308, and a sliding portion is provided on the side of the snap-in groove 309 close to the conveyor belt 303, and the snap-in pin 308 is provided with an inclined portion slidably connected to the sliding portion, so that when the driving end of the pushing member 302 approaches the raw material 100, the snap-in pin 308 slides through the plurality of snap-in grooves 309, and when the pushing head 304 is pressed against the side of the raw material 100, the snap-in pin 308 falls into the snap-in groove 309 and is clamped.

[0030] In the above embodiment, the positioning mechanism 3 also includes a combination of a clamping plate 306 and a clamping pin 308, which significantly enhances the stability of the device during the positioning process. Specifically, the clamping plate 306 is firmly placed below the driving end of the pusher 302, serving as a dual guarantee of support and positioning. The driving end of the pusher 302 is cleverly sleeved with an adjustment frame 307, which provides space for the sliding of the clamping pin 308.

[0031] As a key component connecting the pusher 302 and the clamping plate 306, the clamping pin 308 can slide freely in the adjustment frame 307 and closely cooperate with the sliding part on the clamping plate 306 through the specially designed inclined surface. When the driving end of the pusher 302 approaches the raw material 100, the clamping pin 308 will slide through the multiple clamping grooves 309 along the track of the sliding part. During this process, the interaction between the clamping pin 308 and the clamping grooves 309 ensures that the pusher 302 can move smoothly and stably until the pusher head 304 is accurately pressed against the side of the raw material 100.

[0032] Once the push head 304 reaches the predetermined position and abuts against the raw material 100 , the locking pin 308 falls into the nearest locking groove 309 and locks, thereby achieving a secure positioning of the raw material 100 .

[0033] In one example, the upper end surface of the locking pin 308 protrudes from the adjusting frame 307, and a hanging portion 310 extends from the upper end surface of the locking pin 308, and a tension spring 311 is fixedly connected between the hanging portion 310 and the adjusting frame 307, so that after the pushing head 304 is pressed against the side of the raw material 100, the locking pin 308 is driven to be clamped in the locking groove 309.

[0034] In the above embodiment, the upper end surface of the locking pin 308 protrudes out of the adjustment frame 307 , and a hanging portion 310 is extended as a spacing portion connecting the locking pin 308 and the adjustment frame 307 , providing space for the tension spring 311 .

[0035] One end of the tension spring 311 is fixed on the adjustment frame 307, and the other end is hooked under the hanging part 310. When the pushing head 304 is pressed against the side of the raw material 100 under the action of the driving force, the tension spring 311 exerts its elastic effect, pulling the hanging part 310 and snapping it into the nearest snap-in groove 309.

[0036] In one embodiment, a limiting groove is provided on one side of the pushing head 304 abutting against the raw material 100, the upper end surface of the limiting groove abuts against the upper end surface of the raw material 100, and a receiving groove is provided on the bottom wall of the limiting groove, in which a plurality of balls are installed, the balls protrude from the receiving groove, and the balls are rollingly connected to the side of the raw material 100.

[0037] In the above embodiment, a limiting groove is cleverly provided on the side where the push head 304 abuts against the raw material 100, thereby ensuring the stable positioning of the raw material 100 during the processing. In the receiving groove provided on the bottom wall of the limiting groove, a plurality of balls are installed, so that when the raw material 100 is pushed by the push head 304, its side can be in rolling contact with the balls, and the non-sliding friction greatly reduces the friction force, so that the raw material 100 can move more smoothly to the predetermined position in the horizontal direction, while avoiding the heat and wear caused by friction, and protecting the surface quality of the raw material 100.

[0038] refer to Figure 4 In one embodiment, the thinning component 21 includes a thinning bracket 211 symmetrically arranged on both sides of the raw material 100, and the thinning bracket 211 is rotatably connected to a first thinning roller 212, the bottom end of the first thinning roller 212 presses the raw material 100, and a second thinning roller 213 is arranged below the first thinning roller 212, the upper end surface of the second thinning roller is pressed against the raw material 100, the second thinning roller is rotatably connected to the thinning bracket 211, and one end of the second thinning roller is connected to the driving end of the thinning driving member 214.

[0039] In the above embodiment, the thinning assembly 21 ensures stability and balance during the thinning process through the thinning brackets 211 symmetrically arranged on both sides. The first thinning roller 212 acts as a driven roller, and its bottom end is in close contact with the surface of the raw material 100 to perform thinning on the raw material 100. The second thinning roller located below acts as an active roller by connecting to the thinning driving member 214, and its upper end surface is in close contact with the raw material 100, forming a double-roll thinning operation mode.

[0040] In one embodiment, a thinning movable frame 215 is sleeved on the outer side of the first thinning roller 212, and the thinning movable frame 215 is slidably connected to the thinning bracket 211. The upper end surface of the thinning bracket 211 is connected to a thinning pusher 302216, and the driving end of the thinning pusher 302216 is fixedly connected to the thinning movable frame 215 to drive the first thinning roller 212 to press the raw material 100.

[0041] In the above embodiment, a thinning movable frame 215 is provided on the outer side of the first thinning roller 212, so that the first thinning roller 212 can not only thin the raw material 100 by pressing the bottom end thereof, but also can achieve more precise thinning control by sliding adjustment of the thinning movable frame 215 on the thinning bracket 211. The sliding connection between the thinning movable frame 215 and the thinning bracket 211 ensures the smoothness and stability of the thinning process, while reducing the error that may be caused by directly adjusting the position of the thinning roller. In addition, the thinning pusher 302216 connected to the upper end surface of the thinning bracket 211 serves as a driving source, and its driving end is directly fixedly connected to the thinning movable frame 215.

[0043] In the above embodiment, the embossing assembly 22 ensures uniform processing of both sides of the raw material 100 through the symmetrically arranged embossing brackets 221. The unique texture protrusions on the first embossing roller 222 are customized to fit the complex shape of the bipolar plate flow channel, and the close contact between its bottom end and the raw material 100, coupled with the pressing effect of the second embossing roller 223, form a stable embossing space, ensuring that the flow channel texture is formed in one step without the need for secondary processing.

[0045] In the above embodiment, the feeding assembly 4 ensures the continuity and stability of the raw material 100 during the processing. The feeding bracket 41 serves as a supporting structure, stably carrying a pair of feeding rollers 42. The two rollers are precisely controlled by the feeding drive 43 to achieve synchronous rotation, providing power for the transportation of the raw material 100. The friction layer on the outer wall of the feeding roller 42 is made of a material with a high friction coefficient, which can effectively grasp and push the raw material 100 forward to prevent slipping or deviation during the transmission process. The pressing gap formed between the two feeding rollers 42 is set on the same horizontal plane as the pressing gap of the thinning assembly 21.

[0047] In the above embodiment, the feeding assembly 4 is also provided with a tension sensor, which is connected between the two feeding rollers 42, in order to monitor and feedback the tension value of the raw material 100 during the conveying process in real time. By accurately measuring the tension change of the raw material 100, the tension sensor can ensure that the raw material 100 maintains a constant tension state during the feeding process, avoiding breakage caused by excessive tension or slipping caused by insufficient tension. In addition, the tension sensor can also be linked with the control system to automatically adjust the feeding speed or apply appropriate resistance to optimize the entire feeding process and ensure smooth transmission and precise processing of the raw material 100.
