Figure 2 As shown, a placement plate 5 is welded and fixed on the top of the bottom plate 1, and the placement plate 5 is located between the output shafts of the two first cylinders 2. A battery substrate 6 is placed on the top of the placement plate 5. Connecting rods 3 are welded on the output shafts of the two first cylinders 2, and a connecting clamp 4 is fixed on each connecting rod 3. The battery substrate 6 is located between the two clamps 4, and the two clamps 4 clamp and fix the battery substrate 6.

[0019] Two support rods are limitedly slid on the top of the bottom plate 1, and the two support rods correspond to the two clamping jaws 4 one by one. Each support rod is fixedly connected to the corresponding clamping jaw 4 to ensure that the two clamping jaws 4 move smoothly.

[0020] A mounting plate is welded on the top of the base plate 1, and the second cylinder 7 is fixed with bolts on the mounting plate, and the output shaft of the second cylinder 7 is horizontally facing the placement plate 5. A connecting plate 8 is welded and fixed on the output shaft of the second cylinder 7, and the connecting plate 8 is an inverted L-shaped plate, including a vertical plate and a horizontal plate. The vertical plate is fixedly connected to the output shaft of the second cylinder 7, and the bottom of the vertical plate is inserted into the base plate 1 and slidingly cooperates with the base plate 1 to ensure the smooth sliding of the connecting plate 8. A laser emitter 9 is fixedly assembled on the bottom of the horizontal plate, and the laser emitter 9 is used to drill holes in the battery substrate 6. The laser emitter 9 is an existing device and will not be described in detail here.

[0021] The motor 11 is fixed by bolts at the bottom of the horizontal plate of the connecting plate 8, and the output shaft of the motor 11 is vertically oriented toward the bottom plate 1 and is connected to the grinding head 14 through a transmission member. The grinding head 14 is in contact with the battery substrate 6 in dynamic friction, and is used to grind the burrs in the hole after the battery substrate 6 is punched. The grinding head 14, the laser emitter 9 and the battery substrate 6 are located on the same horizontal straight line, ensuring that when the connecting plate 8 moves horizontally and linearly with the output shaft of the second cylinder 7, the laser emitter 9 and the grinding head 14 can correspond to the battery substrate 6.

[0022] The transmission member includes a connecting block 12 , which is welded and fixed on the output shaft of the motor 11 , and the grinding head 14 is transmission-connected to the connecting block 12 for driving the grinding head 14 to rotate.

[0023] An L-shaped fixing plate 10 is welded to the bottom of the horizontal plate of the connecting plate 8. The vertical plate of the fixing plate 10 is fixedly connected to the horizontal plate of the connecting plate 8. A feeding assembly is assembled on the horizontal plate of the fixing plate 10, the connecting block 12 is in driving cooperation with the feeding assembly, and the feeding assembly is in driving connection with the grinding head 14, which is used to drive the grinding head 14 to approach or move away from the hole punched on the battery substrate 6.

[0024] like Figure 2 and Figure 3 As shown, the feed assembly includes a bolt 13, which is perpendicular to the bottom plate 1 and passes through the fixing plate 10, and the bolt 13 is threadedly connected to the fixing plate 10. The head of the bolt 13 is a square head, and a transmission groove matching the head of the bolt 13 is cut inside the connecting block 12. The head of the bolt 13 is slidably assembled in the transmission groove and is in transmission engagement with the connecting block 12. The end of the bolt 13 away from the head is fixedly connected to the grinding head 14.

[0025] Working principle: When in use, first place the battery substrate 6 on the placement plate 5, then start the two first cylinders 2, the output shafts of the two first cylinders 2 extend out and drive the clamping claws 4 to clamp and fix the battery substrate 6.

[0026] When the battery substrate 6 is fixed, the two first cylinders 2 are closed, and the second cylinder 7 is started. The output shaft of the second cylinder 7 extends and drives the connecting plate 8 to move closer to the placement plate 5. When the laser emitter 9 moves to the top of the battery substrate 6, the second cylinder 7 is closed, and the laser emitter 9 is started to punch holes in the battery substrate 6.

[0027] When the drilling is completed, the laser emitter 9 is turned off, and the second cylinder 7 is started again. The output shaft of the second cylinder 7 is extended and retracted, and the grinding head 14 is driven through the connecting plate 8 to match the hole punched on the battery substrate 6. Then the second cylinder 7 is turned off and the motor 11 is started. The output shaft of the motor 11 drives the connecting block 12 to rotate. The connecting block 12 drives the bolt 13 to rotate through the head of the bolt 13, and the bolt 13 drives the grinding head 14 to rotate. At the same time, since the bolt 13 is threadedly connected to the fixing plate 10, and the fixing plate 10 is fixedly connected to the connecting plate 8, the bolt 13 will drive the grinding head 14 to move closer to the hole punched on the battery substrate 6 during the rotation. When the grinding head 14 contacts the battery substrate 6, the burrs in the hole punched in the battery substrate 6 are polished to make it regular.

[0028] After the grinding is finished, the output shaft of the motor 11 is reversed relative to the previous rotation, thereby driving the connection block 12 to reverse relative to the previous rotation. The connection block 12 drives the bolt 13 to reverse relative to the previous rotation, and the bolt 13 drives the grinding head 14 to rotate away from the battery substrate 6. Then the motor 11 is turned off, and the two first cylinders 2 are started again. The output shafts of the two first cylinders 2 are retracted and drive the two clamps 4 to release the clamping of the battery substrate 6. Then the battery substrate 6 is removed.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
