Description

Technical Field

[0001] This application relates to the field of metal cutting technology, and in particular to a cutting device for pins of new energy battery modules. Background Technology

[0002] In the electronic components of new energy battery modules, the pins have a unique shape, requiring separate cutting of the middle and ends. This typically necessitates the use of multiple tool assemblies to obtain the desired pin product. Current cutting equipment often utilizes machine tools with interchangeable tools to process the pins. While these machines can automatically switch tools, their complexity is extremely high, and the tool switching process is also very intricate, resulting in low production efficiency. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a cutting device for pins of new energy battery modules, which can automatically cut the ends and middle sections of the pins without performing complex tool changing steps, thus achieving high efficiency.

[0004] A pin-cutting device for a new energy battery module according to a first aspect embodiment of this application includes: Clamping assembly for holding pins used in new energy battery modules; A guide rail assembly is provided along a first horizontal direction, and a clamping assembly is movably mounted on the guide rail assembly; A first tool assembly, the rotation axis of the first tool assembly is set horizontally, and the first tool assembly is used to cut the upper part of the middle section of the needle. The second tool assembly has a rotation axis parallel to that of the first tool assembly, and is used to cut the lower part of the middle section of the needle. The third tool assembly has a vertically arranged rotation axis and is used to perform horizontal cutting on the first end of the needle. Fourth tool assembly; A lifting drive assembly is used to drive the fourth tool assembly to perform lifting movements. The rotation axis of the fourth tool assembly is parallel to the first horizontal direction. The fourth tool assembly is used to perform vertical cutting on the first end of the needle. The first tool assembly, the second tool assembly, the third tool assembly, and the fourth tool assembly are arranged sequentially along the first horizontal direction, and the guide rail assembly is used to drive the clamping assembly to perform linear reciprocating motion along the first horizontal direction.

[0005] The pin-cutting device for new energy battery modules according to the embodiments of this application has at least the following beneficial effects: When the pin-cutting device for new energy battery modules is running, the first tool assembly, the second tool assembly, the third tool assembly, and the fourth tool assembly are kept rotating. The pins for new energy battery modules are clamped by the clamping assembly, which specifically clamps the middle section of the pin. The clamping assembly is driven by the guide rail assembly to move the pin linearly along the first horizontal direction. During the movement of the pin along the first horizontal direction, the pin first contacts the first tool assembly. Since the rotation axis of the first tool assembly is set horizontally and is perpendicular to the first horizontal direction, the first tool assembly can cut the upper part of the middle section of the pin that is not clamped by the clamping assembly when it rotates. Then the pin continues to move along the first horizontal direction and contacts the second tool assembly. The second tool assembly cuts the lower part of the middle section of the pin that is not clamped by the clamping assembly when it rotates. In this way, the cutting of the middle section of the pin is completed by the first tool assembly and the second tool assembly. The guide rail assembly continues to drive the clamping assembly to move the needle along the first horizontal direction to approach and contact the third tool assembly, so that the third tool performs a horizontal cut on the first end of the needle. The guide rail assembly continues to drive the clamping assembly to move the needle along the first horizontal direction to approach the fourth tool assembly. Then, the lifting drive assembly drives the fourth tool assembly to move up and down, so that the fourth tool assembly contacts the first end of the needle, completing the vertical cut on the first end. In the cutting device of this embodiment, the first tool assembly, the second tool assembly, and the fourth tool assembly are kept rotating. Then, the guide rail assembly drives the clamping assembly to perform linear reciprocating motion along the first horizontal direction, and the lifting drive assembly drives the fourth tool assembly to perform vertical motion, so that the cutting of the middle section and the first end of the needle can be completed. The device has a compact structure, and the clever design makes the cutting process and the actions of each module relatively simple, without the need to perform complex tool changing procedures, thereby improving cutting efficiency and reducing production costs. Moreover, in the entire cutting process, there is no need to drive the needle to perform complex movements; only the guide rail assembly drives the needle to perform linear motion, which can improve cutting efficiency.

[0023] Reference Figures 1 to 2This application provides a cutting device for pins of a new energy battery module, including a clamping assembly 100, a guide rail assembly 200, a first cutting tool assembly 300, a second cutting tool assembly 400, a third cutting tool assembly 500, a fourth cutting tool assembly 600, and a lifting drive assembly 700. The clamping assembly 100 is used to clamp the pins of the new energy battery module; the guide rail assembly 200 is arranged along a first horizontal direction, and the clamping assembly 100 is movably mounted on the guide rail assembly 200; the first cutting tool assembly 300 is located above a first side of the guide rail assembly 200, the rotation axis of the first cutting tool assembly 300 is horizontally arranged and perpendicular to the first horizontal direction, and the first cutting tool assembly 300 is used to cut the upper part of the middle section of the pin; The second cutting tool assembly 400 is located above the guide rail assembly 200 and below one side of the first cutting tool assembly 300. The rotation axis of the second cutting tool assembly 400 is parallel to the rotation axis of the first cutting tool assembly 300. The second cutting tool assembly 400 is used to cut the lower part of the middle section of the needle. The third cutting tool assembly 500 is located above the second side of the guide rail assembly 200. The rotation axis of the third cutting tool assembly 500 is vertically set. The third cutting tool assembly 500 is used to perform horizontal cutting on the first end of the needle. The fourth cutting tool assembly 600 is located above the second side of the guide rail assembly 200. The lifting drive assembly 700 is used to drive the fourth cutting tool assembly 600 to perform lifting motion. The rotation axis of the fourth cutting tool assembly 600 is parallel to the first horizontal direction. The fourth cutting tool assembly 600 is used to perform vertical cutting on the first end of the needle. The guide rail assembly 200 is used to drive the clamping assembly 100 to reciprocate along the first horizontal direction.

[0024] It is worth noting that, during operation, the cutting equipment for the pins of the new energy battery module first rotates the first tool assembly 300, the second tool assembly 400, the third tool assembly 500, and the fourth tool assembly 600. The clamping assembly 100 clamps the pins for the new energy battery module, specifically clamping the middle section of the pin. The guide rail assembly 200 drives the clamping assembly 100 to move the pin linearly along a first horizontal direction. During this movement, the pin first contacts the first tool assembly 300. Since the rotation axis of the first tool assembly 300 is horizontally set and perpendicular to the first horizontal direction, the first tool assembly 300 can cut the upper part of the middle section of the needle that is not held by the clamping assembly 100 when it rotates. Then the needle continues to move along the first horizontal direction and comes into contact with the second tool assembly 400. When the second tool assembly 400 rotates, it cuts the lower part of the middle section of the needle that is not held by the clamping assembly 100. In this way, the cutting of the middle section of the needle is completed by the first tool assembly 300 and the second tool assembly 400. The guide rail assembly 200 continues to drive the clamping assembly 100 to move the needle along the first horizontal direction to approach and contact the third tool assembly 500, so that the third tool performs horizontal cutting on the first end of the needle. The guide rail assembly 200 continues to drive the clamping assembly 100 to move the needle along the first horizontal direction to approach the fourth tool assembly 600. Then, the lifting drive assembly 700 drives the fourth tool assembly 600 to perform lifting and lowering movements, so that the fourth tool assembly 600 contacts the first end of the needle, completing the vertical cutting on the first end. In the cutting device of this application embodiment, the first tool assembly 300, the second tool assembly 400, and the fourth tool assembly 600 are kept rotating. Then, the clamping assembly 100 is driven to perform linear reciprocating motion in the first horizontal direction by the guide rail assembly 200, and the fourth tool assembly 600 is driven to perform lifting motion by the lifting drive assembly 700. This completes the cutting of the middle section and the first end of the needle. The device has a compact structure, and the clever design makes the cutting process and the actions of each module relatively simple, eliminating the need for complex tool changing procedures, thereby improving cutting efficiency and reducing production costs. Furthermore, during the entire cutting process, there is no need to drive the needle to perform complex movements; only the guide rail assembly drives the needle to perform linear motion, which improves cutting efficiency.

[0025] It should be noted that, referring to Figure 7 The pin includes a first end, a middle section, and a second end, with the middle section located between the first and second ends. The first, middle, and second ends are integrally formed. All three ends are cylinders; the first and second ends have the same diameter, while the middle section has a larger diameter than the first end. (Refer to...) Figure 8After being cut by the cutting equipment, the first end of the needle changes from a cylinder to a cuboid, a part of the middle section of the needle changes from a cylinder to a flat shape, and the second end of the needle does not need to be cut and retains its original shape.

[0026] It is worth noting that the length direction of the guide rail assembly 200 is the first horizontal direction.

[0027] In some embodiments, refer to Figure 1 The first tool assembly 300, the second tool assembly 400, the third tool assembly 500 and the fourth tool assembly 600 are arranged sequentially along the first horizontal direction. The first tool assembly 300 and the second tool assembly 400 are located on the first side of the guide rail assembly 200, while the third tool assembly 500 and the fourth tool assembly 600 are located on the second side of the guide rail assembly 200. The first side and the second side are the opposite sides of the guide rail assembly 200. The first cutting tool includes a first fixed base 310, a first rotary drive 320, a first cutter 330, and a first rotating shaft 340. The first fixed base 310 is disposed on the first side, the first rotary drive 320 is fixed on the first fixed base 310, the first rotating shaft 340 is rotatably connected to the first rotary drive 320, and the first rotating shaft 340 is horizontally disposed. The axial direction of the first rotating shaft 340 is perpendicular to the first horizontal direction, so that the rotation axis of the first cutter 330 is horizontally disposed and perpendicular to the first horizontal direction. The first cutter 330 is vertically disposed on the first rotating shaft 340. The first rotary drive 320 drives the first rotating shaft 340 to rotate the first cutter 330, so that when the upper part of the middle section of the needle contacts the first cutter 330, the first cutter 330 cuts the upper part of the middle section of the needle. It should be noted that those skilled in the art can set the vertical distance between the first cutter 330 and the clamping assembly 100 according to the actual situation, so as to set the cutting depth of the first cutter 330 on the needle; those skilled in the art can set the horizontal distance between the first cutter 330 and the clamping assembly 100 according to the actual situation, so as to set the cutting length of the first cutter 330 on the needle.

[0028] In some embodiments, refer to Figure 2 and Figure 3The second cutting tool includes a second fixed base 410, a second rotary drive 420, a second cutting blade 430, and a second rotating shaft 440. The second fixed base 410 is located on the first side, the second rotary drive 420 is fixed to the first fixed base 310, and the second rotating shaft 440 is rotatably connected to the second rotary drive 420 and is horizontally positioned. Furthermore, the vertical distance between the second rotating shaft 440 and the clamping assembly 100 is less than the vertical distance between the first rotating shaft 340 and the clamping assembly 100, meaning the height of the second rotating shaft 440 is lower than the height of the first rotating shaft 340. The axial direction of the second rotating shaft 440 is perpendicular to the first horizontal direction, so that the rotation axis of the second cutter 430 is horizontally set and perpendicular to the second horizontal direction. The second cutter 430 is vertically mounted on the second rotating shaft 440. The second rotary drive member 420 drives the second rotating shaft 440 to rotate the second cutter 430, so that when the lower part of the middle section of the needle contacts the second cutter 430, the second cutter 430 cuts the lower part of the middle section of the needle. It should be noted that those skilled in the art can set the vertical distance between the second cutter 430 and the clamping assembly 100 according to the actual situation to set the cutting depth of the second cutter 430 on the needle; those skilled in the art can set the horizontal distance between the second cutter 430 and the clamping assembly 100 according to the actual situation to set the cutting length of the second cutter 430 on the needle.

[0029] In some embodiments, refer to Figure 2 and Figure 3 The third tool assembly 500 includes a third fixed base 510, a third rotary drive 520, a third rotating shaft 530, and two third cutters 540. The third fixed base 510 is located on the second side. The third rotary drive 520 is fixed to the third fixed base 510. The third rotating shaft 530 is rotatably connected to the third rotary drive 520 and is vertically arranged. The two third cutters 540 are horizontally arranged on the third rotating shaft 530, spaced apart, and coaxially arranged so that the rotation axis of the third cutters 540 is vertical. The third rotary drive 520 drives the two third cutters 540 to rotate via the third rotating shaft 530, so that when the two third cutters 540 contact the first end of the needle, they perform horizontal cutting on the first end. It should be noted that those skilled in the art can set the horizontal distance between the third cutter 540 and the clamping assembly 100 according to actual conditions to set the cutting length of the third cutter 540 on the needle. Those skilled in the art can set the vertical distance between the third cutter 540 and the clamping assembly 100 according to actual conditions, so as to set the cutting depth of the third cutter 540 on the needle. Those skilled in the art can also set the spacing between the two third cutters 540 according to actual conditions.

[0030] In some embodiments, refer to Figure 2 and Figure 4 The fourth tool assembly 600 includes a fourth fixed base 610, a fourth rotary drive 620, a fourth rotating shaft 630, and two fourth cutters 640. The fourth fixed base 610 is connected to the lifting drive assembly 700. The fourth rotary drive 620 is fixed to the fourth fixed base 610. The fourth rotating shaft 630 is rotatably connected to the fourth rotary drive 620 and is horizontally arranged. The two fourth cutters 640 are vertically arranged on the fourth rotating shaft 630 and are spaced apart and coaxially arranged, so that the rotation axis of the fourth cutter 640 is horizontal and parallel to the first horizontal direction. Furthermore, when the fourth cutter 640 is cutting, the linear guide drive clamping assembly 100 moves close to the fourth cutter 640, causing the clamping assembly 100 to stop. Then, the lifting drive assembly 700 drives the fourth fixed base 610 to move up and down, thereby driving the two fourth cutters 640 to move up and down. Simultaneously, the fourth rotary drive member 620 drives the two fourth cutters 640 to rotate via the fourth rotating shaft 630, so that when the two fourth cutters 640 contact the first end of the needle, they perform vertical cutting on the first end. It should be noted that those skilled in the art can set the horizontal distance between the fourth cutter 640 and the clamping assembly 100 according to actual conditions to set the cutting length of the fourth cutter 640 on the needle. Those skilled in the art can also set the interval between the two fourth cutters 640 according to actual conditions. It should be noted that the axis of rotation refers to the straight line where the center of the circular motion of each point when the object rotates lies. The first rotary drive member 320, the second rotary drive member 420, the third rotary drive member 520, and the fourth rotary drive member 620 are all rotary drive motors. The lifting drive assembly 700 can be a linear drive motor.

[0031] In some embodiments, refer to Figure 2 and Figure 5 The clamping assembly 100 includes a clamping drive 210, a mounting base 220, a first clamping block 230, and a second clamping block 240. The second clamping block 240 is mounted on the mounting base 220. The clamping assembly 100 is mounted on the mounting base 220. The mounting base 220 is movably mounted on the guide rail assembly 200. The clamping drive 210 is connected to the first clamping block 230 and is used to drive the first clamping block 230 to move closer to or away from the second clamping block 240.

[0032] Specifically, the guide rail assembly 200 includes a linear guide rail and a linear drive component. The linear guide rail is arranged along a first horizontal direction. The mounting base 220 is slidably mounted on the linear guide rail. The linear drive component, a linear drive motor, drives the mounting base 220 to perform linear reciprocating motion along the linear guide rail. The clamping drive component 210 is a drive cylinder. The clamping drive component 210 drives the first clamping block 230 to move closer to or away from the second clamping block 240, so that the first clamping block 230 and the second clamping block 240 can clamp or release the needle. After the first clamping block 230 and the second clamping block 240 clamp the needle, the linear drive component drives the mounting base 220 to move the clamping drive component 210, the first clamping block 230, and the second clamping block 240 along the linear guide rail, so that the needle moves sequentially closer to the first tool assembly 300, the second tool assembly 400, the third tool assembly 500, and the fourth tool assembly 600.

[0033] In some embodiments, refer to Figure 2 and Figure 5 The cutting equipment for the pins of new energy battery modules also includes a feeding assembly and a first straightening assembly 830. The first straightening assembly 830 includes a limiting member 831, a first ejector pin 832 and a first driving member 833. The feeding assembly is located on the second side of the guide rail assembly 200. The limiting member 831 has a groove in the horizontal direction and the groove is located on the second side of the guide rail assembly 200. The feeding assembly is used to transport the pins to the groove. The first ejector pin 832 is located in the groove. The first driving member 833 is used to drive the first ejector pin 832 to reciprocate along the groove to push the pins to move closer to the clamping assembly 100.

[0034] It is worth noting that the feeding assembly transfers the needles into the chute, and then the guide rail assembly 200 transports the clamping assembly 100 close to the first straightening assembly 830, so that the first clamping block 230 and the second clamping block 240 are located on one side of the chute, and the chute is located between the first clamping block 230 and the second clamping block 240. Then, the first driving member 833 drives the first ejector pin 832 to move along the chute to push the needles along the chute to the space between the first clamping block 230 and the second clamping block 240. Then, the first clamping block 230 and the second clamping block 240 clamp the needles. In this way, the automated feeding of needles is achieved, improving production efficiency. The first driving member 833 is a driving cylinder.

[0035] It is worth noting that, referring to Figure 6The limiting member 831 is elongated and horizontally positioned, with its length direction perpendicular to the first horizontal direction. A chute is positioned along the length of the limiting member 831, and its width is less than the length of the needle. This arrangement helps to straighten the needle as it falls from the transmission pipe 820 into the chute, ensuring that its orientation is perpendicular to the first horizontal direction. This allows the needle to remain perpendicular to the first horizontal direction even when held by the clamping assembly 100, facilitating cutting by the first cutting tool assembly 300, second cutting tool assembly 400, third cutting tool assembly 500, and fourth cutting tool assembly 600. This ingenious design achieves complex functionality with low equipment cost and without manual assistance, automatically maintaining the needle's orientation as horizontal and perpendicular to the first horizontal direction.

[0036] In some embodiments, refer to Figure 2 The feeding assembly includes a vibratory feeder 810 and a transfer pipe 820. Multiple needles are placed on the vibratory feeder 810. One end of the transfer pipe 820 is connected to the vibratory feeder 810, and the other end is located above the chute. The vibratory feeder 810 is used to transport the needles to the chute through the transfer pipe 820.

[0037] It is worth noting that the transmission pipe 820 can be a rubber tube. One end of the transmission pipe 820 is connected to the vibratory plate 810. The vibratory plate 810 is positioned higher than the chute. Multiple needles are placed on the vibratory plate 810. The vibratory plate 810 transports the needles to the transmission pipe 820 through vibration, and then they fall down along the transmission pipe 820 onto the chute, thereby completing the automated feeding of the needles without the need for manual assistance, thus improving production efficiency.

[0038] In some embodiments, refer to Figure 6 The limiting member 831 is provided with a first guide block 834 and a second guide block 835 at one end near the guide rail assembly 200. The first guide block 834 is located above the second guide block 835. The bottom surface of the first guide block 834 is provided with a first groove, and the top surface of the second guide block 835 is provided with a second groove. A conveying groove communicating with the slide is formed between the first groove and the second groove, and the length direction of the conveying groove is the same as the length direction of the slide. The two opposite side walls of the conveying groove are respectively formed with clearance grooves.

[0039] In some embodiments, both the first guide block 834 and the second guide block 835 are cuboids, and the first groove and the second groove are symmetrical. The first guide block 834 and the second guide block 835 do not contact each other, thus forming a gap between them, which serves as a clearance groove. It is worth noting that after the clamping assembly 100 clamps the needle, the linear guide rail drives the clamping assembly 100 to move the needle horizontally along a first direction. After passing through the clearance groove, the needle moves away from the first guide block 834 and the second guide block 835. The clearance groove prevents the first guide block 834 and the second guide block 835 from obstructing the movement of the needle. The width of the conveying groove is less than the length of the needle, preventing the needle from changing its orientation during movement along the conveying groove.

[0040] In some embodiments, refer to Figure 1 and Figure 5 The pin cutting device for new energy battery modules in this application embodiment further includes a second alignment component 840. The second alignment component 840 includes a second ejector pin 842 and a second driving member 841. The second ejector pin 842 is disposed on the first side of the guide rail assembly 200, and the second ejector pin 842 is positioned opposite to the first ejector pin 832. The second driving member 841 is used to drive the second ejector pin 842 to move closer to or away from the first ejector pin 832.

[0041] It is worth noting that the first ejector pin 832 is located on the second side of the guide rail assembly 200, and the second ejector pin 842 is located on the first side of the guide rail assembly 200. The axes of the first ejector pin 832 and the second ejector pin 842 are on the same straight line, and the guide rail assembly 200 is located between the first ejector pin 832 and the second ejector pin 842. The second driving member 841 is a driving cylinder capable of driving the second ejector pin 842 to move towards or away from the first ejector pin 832. When the guide rail assembly 200 drives the clamping assembly 100 to move close to the second ejector pin 842, and the pin on the clamping assembly 100 is opposite to the second ejector pin 842, the second driving member 841 drives the second ejector pin 842 to move towards the first ejector pin 832 and contact the pin to push it, thereby adjusting the position of the pin in the clamping assembly 100. Alternatively, the first driving member 833 can drive the first ejector pin 832 to contact the pin and adjust its position in the clamping assembly 100. In some scenarios, due to different pin lengths or different cutting requirements, it is necessary to change the relative position of the pins and each cutter in the horizontal direction. In this embodiment, the pins can be pushed by the first ejector pin 832 and the second ejector pin 842 to change the horizontal position of the pins on the clamping assembly 100, thereby changing the relative position of the pins and each cutter in the horizontal direction. This allows the cutting device to be used with pins of different lengths or to meet different cutting requirements without adjusting the position of each cutter. The adjustment process is simpler and more convenient when using pins of different lengths or different cutting requirements.

[0042] In some embodiments, the system further includes a camera assembly (not shown) and a control assembly (not shown). The control assembly is connected to the camera assembly, the guide rail assembly 200, the first drive member 833, the second drive member 841, the clamping drive member 210, the first rotation drive member 320, the second rotation drive member 420, the third rotation drive member 520, and the fourth rotation drive member 620, respectively. The control assembly is used to control the operation of the various components connected to it. The control assembly can be a processor, a microcontroller, or a host computer. The camera assembly is a camera, located above the guide rail assembly 200. The camera assembly is used to capture images of the clamping assembly 100, and the images include the pins clamped by the clamping assembly 100. The camera component is used to capture an image of the clamping component 100 after it clamps the pin output from the slide groove, thereby obtaining a first image. The control component determines a first length of the middle section of the pin located on the first side of the clamping component 100 based on the first image. If the first length is detected to be less than a preset first target length, the control component first controls the first drive member 833 to drive the first ejector pin 832 to abut against the pin, and then controls the first drive member 833 to drive the first ejector pin 832 to move a first distance in a direction closer to the second ejector pin 842. The first distance is the absolute value of the difference between the first target length and the first length.

[0043] Specifically, refer to Figure 9 Before the first cutter 330 cuts the needle, the camera component captures an image of the clamping component 100 to obtain a first image. This first image is then transmitted to the control component. Based on the first image, the control component determines a first length of the portion of the needle located on the first side of the clamping component 100, specifically the length of the middle section of the needle located on the first side and not clamped by the first clamping block 230 and the second clamping block 240. If the first length is detected to be less than the first target length, the first drive member 833 is first controlled to drive the first ejector pin 832 to abut against the needle. Then, the first drive member 833 is controlled to drive the first ejector pin 832 to move a first distance in a direction closer to the second ejector pin 842, so that the needle moves a first distance in a direction closer to the second ejector pin 842, ensuring that the length of the middle section of the needle located on the first side and not clamped by the first clamping block 230 and the second clamping block 240 after the movement is equal to the first target length.

[0044] When the first length is detected to be greater than the first target length, the second driving member 841 is first controlled to drive the second ejector pin 842 to abut against the needle foot, and then the second driving member 841 is controlled to drive the second ejector pin 842 to move a first distance in the direction close to the first ejector pin 832, so that the needle foot moves a first distance in the direction close to the first ejector pin 832, so that the length of the middle section of the needle foot after the movement, which is located on the first side and is not clamped by the first clamping block 230 and the second clamping block 240, is equal to the first target length.

[0045] It should be noted that, typically, after the drive pin moves a first distance, the camera component needs to acquire the first image again, and a new first length is calculated based on the newly acquired first image. If the first length is determined to be equal to the first target length, the guide rail assembly 200 drives the clamping assembly 100 to move along the first horizontal direction, sequentially passing through the first tool assembly 300 and the second tool assembly 400. Those skilled in the art can set the first target length according to actual cutting requirements; this application does not specifically limit the first target length.

[0046] In some embodiments, the camera assembly is further configured to capture an image of the clamping assembly 100 after the second tool assembly 400 completes the cutting operation on the lower part of the middle section of the pin, thereby obtaining a second image; The control component determines the second length of the pin located on the second side of the clamping component 100 based on the second image. When the second length is detected to be less than the preset second target length, the control component drives the guide rail assembly to move the clamping component 100 so that the pin on the clamping component 100 is opposite to the second ejector pin 842. The control component controls the second drive member 841 to drive the second ejector pin 842 to abut against the pin, and then controls the second drive member 841 to drive the second ejector pin 842 to move a second distance along the direction closer to the first ejector pin 832. The second distance is equal to the absolute value of the difference between the second target length and the second length. When the second length is detected to be greater than the second target length, the guide rail assembly is controlled to drive the clamping assembly 100 to move so that the pin on the clamping assembly 100 is opposite to the second ejector pin 842; the first driving member 833 is controlled to drive the first ejector pin 832 to abut against the pin, and then the first driving member 833 is controlled to drive the first ejector pin 832 to move a second distance in the direction close to the second ejector pin 842.

[0047] In some other embodiments, the clamping assembly 100 further includes a lifting cylinder (not shown in the figure), which is movably connected to the guide rail assembly 200. The mounting base 220 is connected to the guide rail assembly 200 via the lifting cylinder, and is specifically mounted on the drive end of the lifting cylinder. The guide rail assembly 200 drives the lifting cylinder to slide along a first horizontal direction, thereby causing the lifting cylinder to drive the mounting base 220 to slide. The lifting cylinder is also used to drive the mounting base 220 to perform lifting movements, thereby changing the height position of the pins. Specifically, in the above steps, after the needle has moved a second distance, if it needs to be cut by the third and fourth tool assemblies 500 and 600, the needle needs to pass through the first tool assembly 300 and the second tool assembly 400 again. Since the middle section has already been cut, to avoid the first and second tool assemblies 300 and 400 cutting again, the needle can be driven to descend by a lifting cylinder to avoid the first and second tool assemblies 300 and 400, thus preventing repeated cutting by them. After passing through the first and second tool assemblies 300 and 400, the needle is then driven to rise to a preset height by the lifting cylinder. Furthermore, the height of the needle can be freely adjusted by the lifting cylinder to adapt to different cutting requirements, thus eliminating the need to adjust the height of each cutter.

[0048] It should be noted that, typically, after the drive pin moves a second distance, a second image needs to be acquired again via the camera component. A new second length is calculated based on this newly acquired image. If the second length is determined to be equal to the second target length, the control guide assembly 200 drives the clamping assembly 100 to move along the first horizontal direction, sequentially passing through the third tool assembly 500 and the fourth tool assembly 600. Those skilled in the art can set the second target length according to actual cutting requirements; this application does not specifically limit the second target length. It should also be noted that this application does not specifically limit the method for determining the first length from the first image or the method for determining the second length from the second image. Those skilled in the art can calculate the first and second lengths using existing edge detection algorithms.

[0049] In some embodiments, refer to Figure 2 and Figure 3 The cutting equipment for the pins of new energy battery modules also includes a feeding assembly 900. The feeding assembly 900 includes a third drive member 910 and a third ejector pin 920. The third ejector pin 920 is located on one side of the guide rail assembly 200. The third drive member 910 drives the third ejector pin 920 to move in a direction close to the clamping assembly 100, so that the third ejector pin 920 pushes the pin out of the clamping assembly 100. The third drive member 910 is a drive cylinder.

[0050] In some embodiments, a material box is provided on one side of the fourth tool assembly 600, and the material box is located below the third ejector pin 920. After the third ejector pin 920 pushes the needle out of the clamping assembly 100, the needle falls into the material box, thereby completing the unloading. This realizes automated unloading without manual assistance and improves production efficiency.

[0051] In some embodiments, refer to Figure 1 The cutting equipment for pins in new energy battery modules also includes a machine base 1000, a first tool assembly 300, a second tool assembly 400, a third tool assembly 500, a fourth tool assembly 600, a guide rail assembly 200, a first alignment assembly 830, a second alignment assembly 840, and a blanking assembly 900, all mounted on the machine base 1000. The fact that all modules or components are mounted on the machine base 1000 allows for a compact structure and facilitates the handling of the cutting equipment.

[0052] In some embodiments, the machine base 1000 is provided with a protective cover, which has an upward opening structure. The first tool assembly 300, the second tool assembly 400, the third tool assembly 500, the fourth tool assembly 600, the guide rail assembly 200, the first straightening assembly 830, the second straightening assembly 840, and the unloading assembly 900 are all located inside the protective cover.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
