[0027] As Figures 1-4 shown, this embodiment provides an automatic edge trimming device, which includes a tool holder 10, an edge trimming assembly, a crushing assembly, a first driving mechanism, and a second driving mechanism. The edge trimming assembly and the crushing assembly of this embodiment are arranged on the tool holder 10; the first driving mechanism is used to drive the tool holder 10 to move along the cutting direction, so that the edge trimming assembly can cut the edge of the battery assembly 80; the second driving mechanism is used to drive the tool holder 10 to move perpendicular to the cutting direction to adjust the cutting depth of the edge trimming assembly.

[0028] The first driving mechanism of this embodiment includes a guide rail 60 extending along the cutting direction, a sliding seat 61 movably arranged on the guide rail 60, and a first driver for driving the sliding seat 61 to move. The first driver of this embodiment preferably uses a stepping motor, which is not only convenient to control but also can improve the accuracy of the movement of the sliding seat 61.

[0029] The second driving mechanism of this embodiment includes a second driver 70 arranged on the sliding seat 61. The second driver 70 preferably uses a cylinder, so that the second driver 70 can directly push the tool holder 10 to move perpendicular to the cutting direction, and its structure is simple. In some embodiments, other conventional drivers can be selected to drive the tool holder 10 according to requirements, and a conventional guiding structure can also be arranged to guide the tool holder 10 according to requirements.

[0030] Specifically refer to Figures 3-4, the cutting tool 20 of this embodiment is detachably connected to the tool holder 10 through the tool rest 21 to facilitate the replacement of the cutting tool 20 after wear. The tool rest 21 is preferably plate-shaped, fixedly connected to the tool holder 10, and the tool rest 21 is preferably connected to the cutting tool 20 by bolts. Its structure is simple and convenient for disassembling and assembling the cutting tool 20. A strip-shaped groove 22 is preferably formed on the blade body of the cutting tool 20. The strip-shaped groove 22 extends along the thickness direction of the battery assembly 80. Bolts are inserted into the strip-shaped groove 22 to connect the tool rest 21. By adjusting the position of the bolts in the strip-shaped groove 22, the height of the cutting tool 20 relative to the tool rest 21 can be adjusted, effectively meeting the trimming requirements of battery assemblies 80 with different thicknesses. The second driver 70 of this embodiment can be selectively connected to the tool rest 21 to push the tool holder 10 to move perpendicular to the cutting direction. It should be noted that when the cutting tool 20 cuts the edge of the battery assembly 80, the blade body of the cutting tool 20 is parallel to the cutting direction, so that the cutting edge 201 of the cutting tool 20 moves along the cutting direction. The relative position between the cutting tool 20 and the battery assembly 80 is common knowledge and will not be elaborated in this embodiment.

[0031] Specifically refer to Figures 2-4 , the crushing assembly of this embodiment includes a driving crushing roller 30, a driven crushing roller 31, and a crushing driver 33. A hollow crushing cavity 13 is formed inside the tool holder 10 of this embodiment. The driving crushing roller 30 and the driven crushing roller 31 are rotatably arranged in the crushing cavity 13, and the central axes of the driving crushing roller 30 and the driven crushing roller 31 are perpendicular to the cutting direction, so that the driving crushing roller 30 and the driven crushing roller 31 are arranged radially in the crushing cavity 13. The crushing driver 33 is used to drive the driving crushing roller 30 to rotate. When the waste enters the crushing cavity 13, the rotating driving crushing roller 30 can guide the waste to move between the driving crushing roller 30 and the driven crushing roller 31, so that the waste passes through the gap between the driving crushing roller 30 and the driven crushing roller 31 to improve the crushing effect of the waste. The requirements for the rotation speed of the driving crushing roller 30 in the crushing assembly are relatively low, which can reduce the noise generated during the crushing process and improve the crushing effect of the waste.

[0032] Specifically refer to Figures 2-4 , the driving crushing roller 30 of this embodiment is preferably provided with spiral crushing blades on its outer peripheral wall, and the outer peripheral wall of the driven crushing roller 31 is preferably a smooth arc surface, and its structure is simple. In some embodiments, suitable blades can be provided on the outer peripheral walls of the driving crushing roller 30 and the driven crushing roller 31 according to needs to further improve the crushing effect. The crushing driver 33 of this embodiment is preferably a motor, and the crushing driver 33 is fixedly arranged on the tool holder 10 and located on the side of the tool holder 10 away from the cutting tool 20 to avoid the crushing driver 33 interfering with the cutting tool 20 when cutting the battery assembly 80.

[0033] Specifically refer to Figures 2-4, the automatic edge trimming device of this embodiment further includes a guide member 40 corresponding to the cutting tool 20. The guide member 40 is located on the cutting edge 201 side of the cutting tool 20, that is, when the cutting tool 20 moves along the cutting direction, the guide member 40 is located in front of the cutting tool 20. The guide member 40 includes a guide channel 41 for communicating with the crushing chamber 13; at the opening of the guide channel 41, a first stop block 42 and a second stop block 43 are provided along the thickness direction of the battery assembly 80. The first stop block 42 and the second stop block 43 extend beyond the cutting tool 20 in the direction perpendicular to the cutting direction, that is, the first stop block 42 and the second stop block 43 are closer to the edge of the battery assembly 80 to be cut, and the cutting tool 20 is farther from the edge of the battery assembly 80 to be cut, so that the first stop block 42 and the second stop block 43 can block the cut waste from leaving the guide channel 41 across the first stop block 42 and the second stop block 43; a gap 44 for avoiding the battery assembly 80 is formed between the first stop block 42 and the second stop block 43 to prevent the first stop block 42 and the second stop block 43 from interfering with the battery assembly 80. The first stop block 42 and the second stop block 43 of this embodiment are preferably made of flexible materials to prevent the first stop block 42 and the second stop block 43 from scratching or bumping the battery assembly 80. It should be noted that the specific shape of the guide member 40 can be adjusted adaptively according to the actual situation, which will not be elaborated in this embodiment. The flexible materials of this embodiment include but are not limited to conventional materials such as rubber and plastic that can be made into stop blocks and have a relatively small hardness.

[0034] When the cutting tool 20 cuts the battery assembly 80, the edge of the battery assembly 80 is located in the gap 44, and the waste cut by the cutting tool 20 enters the crushing chamber 13 through the guide channel 41 under the restriction of the first stop block 42 and the second stop block 43; the waste entering the crushing chamber 13 is crushed under the action of the active crushing roller 30 and the driven crushing roller 31; the crushed waste falls to the bottom of the crushing chamber 13.

[0035] Specifically refer to Figure 2 , the tool holder 10 of this embodiment preferably includes a seat body 11 and two cover plates 12. The crushing chamber 13 is formed on the seat body 11, and the two cover plates 12 are covered on both sides of the seat body 11 perpendicular to the cutting direction to seal the crushing chamber 13. Its structure is simple and it is convenient to process the crushing chamber 13 in the tool holder 10. Preferably, bearing holes are provided on the two cover plates 12 of this embodiment, and bearings 32 are embedded in the bearing holes to correspondingly connect the two ends of the active crushing roller 30 and the driven crushing roller 31, so that the active crushing roller 30 and the driven crushing roller 31 are rotatably arranged in the crushing chamber 13. In this embodiment, the bearings 32 are embedded on the two cover plates 12, which can not only prevent the bearings 32 from occupying the internal space of the crushing chamber 13, but also facilitate opening holes on the cover plates 12 and assembling the bearings 32. In some embodiments, the bearings 32 can be arranged on the seat body 11 or other components according to requirements.

[0036] Specifically refer to Figures 3-4, a normally closed bottom cover 50 is provided at the bottom of the crushing chamber 13 of this embodiment. The bottom cover 50 is hinged to the bottom of the cutter base 10, and the crushing chamber 13 is opened or closed by flipping the bottom cover 50. When the edge trimming device is working normally, the bottom cover 50 closes the crushing chamber 13 to ensure that the crushed waste is concentrated at the bottom of the crushing chamber 13; when the waste needs to be collected, the bottom cover 50 is flipped to open the crushing chamber 13, and the crushed waste falls out of the crushing chamber 13, facilitating the collection of the crushed waste.

[0037] An aggregate driver 51 for controlling the flipping of the bottom cover 50 is provided on the cutter base 10 of this embodiment. The aggregate driver 51 of this embodiment preferably uses a cylinder. One end of the aggregate driver 51 is hinged to the bottom of the cutter base 10, and the other end is hinged to the bottom cover 50. During the telescoping process of the aggregate driver 51, the flipping angle of the bottom cover 50 can be controlled, thereby opening or closing the crushing chamber 13. Specifically, a support 501 is formed at the end of the bottom cover 50. The proximal end (the end close to the bottom cover 50) of the support 501 is hinged to the bottom of the bottom cover 50; the cylinder body part of the cylinder is hinged to the bottom of the cutter base 10, and the cylinder rod is hinged to the distal end (the end far from the bottom cover 50) of the support 501. When the cylinder rod telescopes, the cylinder rod pushes the support 501 to rotate around the hinge at the proximal end, and the rotating support 501 drives the bottom cover 50 to flip synchronously, so that the bottom cover 50 opens or closes the crushing chamber 13.

[0038] It should be noted that the aggregate driver 51 can also be selected as a conventional driver such as a motor or an electric push rod according to requirements.

[0039] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0040] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
