Description

Technical Field

[0001] This invention relates to the field of battery processing and manufacturing technology, and in particular to a battery grooving device. Background Technology

[0002] With the development of technology, more and more electronic devices are used in people's lives, and the demand for batteries is increasing. In the manufacturing process of cylindrical batteries, the grooving process of the battery's steel casing is a key process.

[0003] Traditional battery grooving devices stretch and thin the grooves during the grooving process, making them prone to cracking or breaking, thus reducing the quality of the grooves and consequently the battery quality. Furthermore, when the grooving mechanism feeds the battery into the groove, the battery's steel casing is prone to radial displacement, significantly affecting the stability of the grooving process.

[0004] Therefore, there is an urgent need to invent a battery grooving device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a battery grooving device to improve the quality and stability of grooving processing and thus improve battery quality.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A battery grooving device, comprising:

[0008] The rotating mechanism is configured to drive the battery steel casing to rotate.

[0021] A limiting roller is rotatably mounted on the other side of the limiting mounting bracket, and the limiting roller rolls against the outer periphery of the battery steel shell.

[0022] As a preferred embodiment, the axial limiting mechanism includes a pressing component, a pressing drive component, and a shaping drive component. The pressing component is connected to the output end of the pressing drive component. The pressing drive component can drive the pressing component to press the battery steel shell. After the grooving mechanism grooves the battery steel shell, the shaping drive component can drive the pressing component to continue moving closer to the battery steel shell to flatten the upper end of the grooving.

[0023] As a preferred embodiment, the pressing drive component is a pre-pressing cam, the shaping drive component is a shaping cam, the pre-pressing cam and the shaping cam are coaxially arranged, and the lower edge of the shaping cam is lower than the lower edge of the pre-pressing cam. The shaping roller of the pressing assembly abuts against the shaping cam, and the pressing roller of the pressing assembly abuts against the pre-pressing cam. When the pressing roller rolls to the lower edge of the pre-pressing cam, the pressing assembly presses the battery steel shell tightly; when the shaping roller rolls to the lower edge of the shaping cam, the pressing assembly flattens the upper end of the groove.

[0024] As a preferred embodiment, the pressing component includes:

[0026] The pressure head is fixed to the lower end of the drive shaft. The end of the battery steel shell can be embedded in the pressure head, and the pressure head can press down on the battery steel shell and rotate the battery steel shell.

[0027] As a preferred embodiment, the pressure head component includes:

[0028] The pressure head body is fixed to the lower end of the drive shaft; and

[0029] A limiting sleeve is fitted and fixed on the outer periphery of the pressure head body, and a snap-fit ​​groove is formed between the pressure head body and the limiting sleeve, and the end of the battery steel shell can be embedded in the snap-fit ​​groove.

[0030] As a preferred embodiment, the pressure head further includes:

[0031] The pressure plate and the elastic element are arranged between the pressure head body and the pressure plate. The pressure plate is movably inserted inside the pressure head body. When the pressure head presses down on the battery steel shell, the pressure head body can flatten the upper end of the groove of the battery steel shell, and the pressure plate can fit against the manifold inside the battery steel shell.

[0032] As a preferred embodiment, the rotating mechanism includes:

[0033] Rotary drive assembly; and

[0036] As a preferred embodiment, the lifting drive component is a lifting cam component, and the lifting roller of the lifting assembly abuts against the lifting cam component. When the lifting roller rolls to the upper edge of the lifting cam component, the lifting assembly lifts the battery steel shell.

[0037] As a preferred embodiment, the battery grooving device further includes a reset mechanism, which includes independently configured first reset component, second reset component, and third reset component. The lifting component moves downward to reset under the action of the first reset component; the pressing component moves upward to reset under the action of the second reset component; and the grooving mechanism rotates to reset in a direction away from the battery steel shell under the action of the third reset component.

[0038] The beneficial effects of this invention are:

[0039] The battery grooving device provided by this invention, by setting an axial limiting mechanism that can move along the axial direction of the battery steel shell, axially limits the rotating battery steel shell, allowing the battery steel shell to be grooved under axially limited conditions. This avoids the risk of the groove becoming thinner due to stretching, improves the quality of grooving, and thus enhances the quality of the battery. Furthermore, by setting a radial limiting mechanism located on one side of the battery steel shell in the radial direction, and abutting against the outer periphery of the battery steel shell, when the grooving mechanism feeds towards the rotating battery steel shell and the radial limiting mechanism to groove it, the radial limiting mechanism provides a reaction force to the battery steel shell, further improving the stability of grooving and the quality of the battery.

[0055] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0056] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0057] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0058] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0059] Traditional battery grooving devices stretch and thin the grooves during the grooving process, making them prone to cracking or breaking, thus reducing the quality of the grooves and consequently the battery quality. Furthermore, when the grooving mechanism feeds the battery into the groove, the battery's steel casing is prone to radial displacement, significantly affecting the stability of the grooving process.

[0060] To solve the above problems, such as Figure 1As shown, this embodiment provides a battery grooving device 100, which includes a rotating mechanism 1, an axial limiting mechanism 2, a radial limiting mechanism 3, and a grooving mechanism 4. The rotating mechanism 1 drives the battery steel shell 200 to rotate. The axial limiting mechanism 2 is disposed on both sides of the battery steel shell 200 in the axial direction and can move along the axial direction of the battery steel shell 200 to axially limit the rotating battery steel shell 200. The radial limiting mechanism 3 is located on one side of the battery steel shell 200 in the radial direction and abuts against the outer periphery of the battery steel shell 200. The grooving mechanism 4 is disposed opposite to the radial limiting mechanism 3 and can feed towards the battery steel shell 200 and the radial limiting mechanism 3 to groove the rotating battery steel shell 200. By setting the axial limiting mechanism 2, when the grooving mechanism 4 feeds into the rotating battery steel shell 200 for grooving, the battery steel shell 200 is grooved under axial limiting conditions. This avoids the risk of the groove becoming thinner due to stretching and the risk of the grooving breaking, thus improving the quality of the grooving and consequently enhancing the quality of the battery. Furthermore, by setting the radial limiting mechanism 3, when the grooving mechanism 4 feeds into the rotating battery steel shell 200 for grooving, the radial limiting mechanism 3 provides a reaction force to the battery steel shell 200, further improving the stability of the grooving and the quality of the battery.

[0061] In addition, such as Figure 1 As shown, the battery grooving device 100 provided in this embodiment also includes an installation mechanism 5 and a linkage drive mechanism 6. The battery steel shell 200 is movably placed in the installation mechanism 5, the axial limiting mechanism 2 is slidably disposed on the installation mechanism 5, and the grooving mechanism 4 is rotatably disposed on the installation mechanism 5. The installation mechanism 5 provides support for the axial limiting mechanism 2 and the grooving mechanism 4. The linkage drive mechanism 6 includes a rotating shaft assembly 61, on the outer peripheral wall of the rotating shaft assembly 61, which is fixed with the installation mechanism 5. The rotating shaft assembly 61 can synchronously drive the installation mechanism 5, the axial limiting mechanism 2, and the grooving mechanism 4 to rotate, so that while the axial limiting mechanism 2 axially limits the rotating battery steel shell 200, it synchronously drives the grooving mechanism 4 to feed towards the battery steel shell 200 and the radial limiting mechanism 3. This realizes the linkage operation of the axial limiting mechanism 2 and the grooving mechanism 4 on the battery steel shell 200, which is simple to operate and greatly improves the processing efficiency of grooving the battery steel shell 200. It should be noted that multiple mounting mechanisms 5 are arranged at intervals along the circumference on the outer peripheral wall of the rotating shaft assembly 61, and each mounting mechanism 5 is provided with a set of axial limiting mechanisms 2, a set of radial limiting mechanisms 3 and a set of grooving mechanisms 4, which further improves the processing efficiency of grooving the battery steel shell 200.

[0062] In addition, such as Figure 1As shown, the linkage drive mechanism 6 also includes a linkage drive component 63. The output end of the linkage drive component 63 is connected to the rotating shaft assembly 61, and the linkage drive component 63 can drive the rotating shaft assembly 61 to rotate. Specifically, the linkage drive component 63 includes a rotary motor 631, a reducer 632, a driving wheel 633, and a driven wheel 634. The output end of the rotary motor 631 is connected to the reducer 632 via a transmission chain. The output end of the reducer 632 is connected to the driving wheel 633. The driving wheel 633 meshes with the driven wheel 634, and the driven wheel 634 is connected to the rotating shaft assembly 61. When the rotary motor 631 rotates, it can sequentially drive the rotating shaft assembly 61 to rotate via the reducer 632, the driving wheel 633, and the driven wheel 634. The design of the linkage drive component 63 ensures more reliable driving of the rotating shaft assembly 61 and guarantees the transmission ratio from the rotary motor 631 to the rotating shaft assembly 61.

[0063] Now combined Figure 2 The specific structure of the radial limiting mechanism 3 is described below, such as... Figure 2 As shown, the radial limiting mechanism 3 includes an annular guide plate 31 and limiting components 32. The annular guide plate 31 surrounds the outer periphery of the rotating shaft assembly 61 and each mounting mechanism 5. Each mounting mechanism 5 is correspondingly provided with a set of limiting components 32. The limiting components 32 are set on the corresponding mounting mechanism 5. One side of the limiting component 32 rolls against the inner wall of the annular guide plate 31, and the other side rolls against the outer periphery of the battery steel shell 200. When the rotating shaft assembly 61 synchronously drives the mounting mechanism 5, the axial limiting mechanism 2, and the limiting components 32 to rotate relative to the annular guide plate 31 to perform grooving, the limiting components 32, under the limiting action of the annular guide plate 31, can always roll against the outer periphery of the battery steel shell 200, thereby achieving radial limiting of the battery steel shell 200.

[0064] Preferably, such as Figure 2As shown, the limiting component 32 includes a limiting mounting frame 321, an adjusting roller 322, and a limiting roller 323. The limiting mounting frame 321 is mounted on the corresponding mounting mechanism 5. The adjusting roller 322 is rotatably mounted on one side of the limiting mounting frame 321, rolling against the inner wall of the annular guide plate 31. The limiting roller 323 is rotatably mounted on the other side of the limiting mounting frame 321, rolling against the outer periphery of the battery steel shell 200. When the mounting mechanism 5 drives the limiting mounting frame 321 to rotate relative to the annular guide plate 31, the adjusting roller 322, limited by the annular guide plate 31, ensures that the limiting roller 323 always rolls against the outer periphery of the rotating battery steel shell 200, thus limiting the radial direction of the battery steel shell 200. Furthermore, this limiting component 32 has a simple structure and reliable operation. By limiting the movement through rolling contact, it greatly improves the protection of the battery steel shell 200.

[0065] In this embodiment, as Figures 1-4 As shown, the axial limiting mechanism 2 includes a lifting assembly 21, a pressing assembly 22, a lowering drive component, and a lifting drive component 25. The lifting assembly 21 is located below the battery steel shell 200, and the pressing assembly 22 is located above the battery steel shell 200. The lowering drive component is a lowering cam component, and the lifting drive component 25 is a lifting cam component. The linkage drive mechanism 6 also includes a pushing cam component 62. The lowering cam component is located above the pressing assembly 22, the lifting cam component is located above the lifting assembly 21, and the pushing cam component 62 is located on one side of the grooving mechanism 4. When the rotating shaft assembly 61 drives the mounting mechanism 5 and the lifting assembly 21, the mechanism is activated. 1. During the rotation of the pressing component 22 and the grooving mechanism 4 relative to the lowering drive component, the lifting drive component 25, and the pushing cam component 62, the pressing component 22 rotates along the lower end face of the lowering cam component, so as to slide downward relative to the mounting mechanism 5 under the action of the lowering cam component. The lifting component 21 rotates along the upper end face of the lifting cam component, so as to move upward relative to the mounting mechanism 5 under the action of the lifting cam component to lift the battery steel shell 200. The grooving mechanism 4 rotates along the wheel edge of the pushing cam component 62, so as to rotate relative to the mounting mechanism 5 under the action of the pushing cam component 62 and feed the rotating battery steel shell 200 into the grooving groove. It should be noted that the lower end face of the lowering cam component has an uneven structure. When the pressing component 22 rotates to the high position along the lower end face of the lowering cam component, it can be pressed down by the high position of the lowering cam component. Similarly, the upper surface of the lifting cam is also uneven. When the lifting assembly 21 rotates to its high position along the upper surface of the lifting cam, the lifting assembly 21 can be lifted by the high position of the lifting cam. The pushing cam 62 can be a disc cam. When the grooving mechanism 4 rotates relative to the wheel edge of the disc cam to its high position, the grooving mechanism 4 can be pushed by the disc cam to rotate relative to the mounting mechanism 5 and feed the grooving groove onto the rotating battery steel shell 200.

[0066] It should be noted that during the lifting process, the lifting assembly 21 can lift and move the rotating battery steel shell 200 upwards. To ensure the stability of the upward movement of the battery steel shell 200, the mounting mechanism 5 includes a connected mounting plate 51 and a guide claw 52. Both the pressing assembly 22 and the lifting assembly 21 are slidably mounted on the mounting plate 51. The grooving mechanism 4 is rotatably connected to the mounting plate 51. The guide claw 52 is used to accommodate the battery steel shell 200. When the lifting assembly 21 lifts the battery steel shell 200, the battery steel shell 200 can move upwards along the guide claw 52. By setting the guide claw 52, ​​a guiding effect is provided for the lifting movement of the battery steel shell 200, ensuring the reliability and stability of the movement of the battery steel shell 200. Specifically, the guide claw 52 is adapted to the outer contour of the battery steel shell 200, thereby ensuring the reliability of the guide claw 52 in guiding the battery steel shell 200.

[0067] Now combined Figures 2-4 The specific structure of the pressure-down assembly 22 is described below, such as... Figures 2-4 As shown, the pressing assembly 22 includes a pressing roller 221, a pressing mounting bracket 222, a drive shaft 223, and a pressing head 224. The pressing roller 221 rolls against the lower end face of the descending cam. The pressing mounting bracket 222 is slidably connected to the mounting plate 51. The pressing roller 221 is rotatably mounted on the pressing mounting bracket 222. The drive shaft 223 is rotatably connected to the pressing mounting bracket 222. The rotating mechanism 1 can drive the drive shaft 223 to rotate. The pressing head 224 is fixed to the lower end of the drive shaft 223. The lifting assembly 21 can push the upper end of the battery steel shell 200 into the pressing head 224, and the pressing head 224 can press down on the battery steel shell 200. When the lifting assembly 21 pushes the upper end of the battery steel shell 200 into the pressure head 224, it not only achieves axial positioning of the battery steel shell 200, but also facilitates the rotation mechanism 1 to drive the battery steel shell 200 in the pressure head 224 to rotate via the transmission shaft 223. Furthermore, when the pressing roller 221 rotates along the lower end face of the descending cam, the pressing roller 221, under the downward pressure of the descending cam at its high position, can drive the pressure head 224 to press down on the battery steel shell 200 via the pressing mounting bracket 222 and the transmission shaft 223.

[0068] Specifically, such as Figure 5As shown, the pressure head component 224 includes a pressure head body 2241 and a limiting sleeve 2242. The pressure head body 2241 is fixed to the lower end of the drive shaft 223, and the limiting sleeve 2242 is sleeved and fixed on the outer periphery of the pressure head body 2241. A locking groove 2243 is formed between the pressure head body 2241 and the limiting sleeve 2242. The lifting component 21 can push the upper end of the battery steel shell 200 into the locking groove 2243, so that the battery steel shell 200 is axially limited under the combined action of the upper locking groove 2243 and the lower lifting component 21. It should be noted that the grooving mechanism 4 grooves the part of the battery steel shell 200 below the locking groove 2243, so the locking groove 2243 will not obstruct or interfere with the grooving process. In addition, an annular clearance groove is provided on the outer peripheral wall of the pressure head body 2241, thereby ensuring that a snap-fit ​​groove 2243 is formed between the outer peripheral wall of the pressure head body 2241 and the inner wall of the limiting sleeve 2242.

[0069] It should be noted that, as Figures 1-3As shown, the pressing roller component 221 includes pressing rollers 2211 and shaping rollers 2212 spaced apart. The pressing rollers 2211 are rotatably mounted on a fixed plate, which is connected to the pressing mounting bracket 222 by a spring. The shaping rollers 2212 are rotatably mounted on the pressing mounting bracket 222. The descending cam component includes a pressing drive component 23 and a shaping drive component 24. The pressing drive component 23 is a pre-pressing cam, and the shaping drive component 24 is a shaping cam. The pre-pressing cam and the shaping cam are coaxially arranged, and the lower edge of the shaping cam is lower than the pre-pressing cam. The lower edge of the cam, the shaping cam surrounds the outer periphery of the preload cam, the pressing roller 2211 rolls against the lower end face of the preload cam, and the shaping roller 2212 rolls against the lower end face of the shaping cam. When it is necessary to groove the battery steel shell 200, the pressing roller 2211 and the shaping roller 2212 rotate synchronously along the lower end face of the corresponding cam. The pressing roller 2211 first abuts against the high position of the lower edge of the preload cam, so that the pressing head 224 moves down a certain distance under the drive of the pressing roller 2211. At this time, the lifting assembly 21 is in the lifting cam Under the action of the component, the battery steel shell 200 is pushed into the snap-fit ​​groove 2243 of the pressure head component 224. Simultaneously, under the action of the push cam component 62, the grooving mechanism 4 grooves the part of the battery steel shell 200 below the snap-fit ​​groove 2243. After the grooving is completed, the shaping roller 2212 is exactly abutting against the high position of the lower edge of the shaping cam, so that the shaping roller 2212 drives the pressure head component 224 to move down a certain distance, thereby flattening the upper end 210 of the groove of the battery steel shell 200, realizing the shaping operation of the groove of the battery steel shell 200, and then pressing down the roller. As the rollers 2211 and 2212 continue to rotate, the pressing roller 2211 abuts against the unloading point 231 at the high position of the lower edge of the pre-pressing cam, allowing the pressing head body 2241 in the pressing head component 224 to continue pressing down on the upper end 210 of the grooving groove. Since the lifting component 21 has moved downward and reset at this time, the grooving mechanism 4 also resets and stops grooving, allowing the battery steel shell 200 to disengage from the snap-fit ​​groove 2243 and reset into the guide claw 52, ​​completing the unloading process of the battery steel shell 200 for the next round of processing. It should be noted that since the fixing plate on the pressing roller 2211 is connected to the pressing mounting bracket 222 by a spring, when the 2212 drives the pressing head component 224 to move down a certain distance, the pressing roller 2211 can always roll and abut against the pre-pressing cam under the action of the spring.

[0070] Specifically, such as Figure 5As shown, the pressing head 224 also includes a pressing plate 2244 and an elastic element 2245. The elastic element 2245 is disposed between the pressing head body 2241 and the pressing plate 2244. The pressing plate 2244 is movably inserted inside the pressing head body 2241. When the pressing head 224 is driven by the shaping roller 2212 to press down on the battery steel shell 200, the pressing head body 2241 can flatten the upper end 210 of the groove of the battery steel shell 200, and the pressing plate 2244 can fit against the manifold 220 inside the battery steel shell 200, thereby realizing the shaping operation of the battery steel shell 200 after grooving, making the quality of grooving more reliable and stable. In addition, by setting the elastic element 2245 between the pressing head body 2241 and the pressing plate 2244, the pressing plate 2244 is prevented from rigidly pressing against the manifold 220, thus improving the protection of the manifold 220. Specifically, the elastic element 2245 can be a compression spring, which has the advantages of good elasticity and low cost. Furthermore, to improve the protection of the busbar 220, a rubber pad can be installed on the upper surface of the busbar 220. It should be noted that the busbar 220 is located at the upper end of the winding core 230, and both the winding core 230 and the busbar 220 are located inside the battery steel casing 200.

[0071] Now combined Figure 1 and Figure 3 The specific structure of the rotating mechanism 1 is described below, such as... Figure 1 and Figure 3 As shown, the rotating mechanism 1 includes a rotating drive assembly 11 and a transmission assembly 12. The transmission assembly 12 includes a first gear 121 and a second gear 122 that mesh externally. The first gear 121 is rotatably mounted on the upper end of the rotating shaft assembly 61. The second gear 122 is slidably sleeved on the transmission shaft 223 and is connected to the transmission shaft 223, allowing the transmission shaft 223 to rotate while also being driven by the second gear 122 to move axially relative to the second gear 122. The rotating shaft assembly 61 is a hollow shaft structure. The output end of the rotating drive assembly 11 can pass through the rotating shaft assembly 61 and be connected to the first gear 121. By driving the first gear 121 to rotate, the rotating drive assembly 11 drives the second gear 122, the transmission shaft 223, and the pressure head 224 to rotate, thereby achieving the rotation of the battery steel shell 200. Specifically, the rotating drive assembly 11 can be a motor, which has the advantages of reliable operation and easy installation.

[0072] Now combined Figure 4 The specific structure of the lifting component 21 is described below, such as... Figure 4As shown, the lifting assembly 21 includes a lifting roller 211, a lifting mounting frame 212, and a lifting seat 213. The lifting roller 211 rolls against the upper surface of the lifting cam component, the lifting mounting frame 212 is slidably connected to the mounting plate 51, the lifting roller 211 is rotatably mounted on the lifting mounting frame 212, and the lifting seat 213 is rotatably mounted on the lifting mounting frame 212. The lifting seat 213 can lift the battery steel shell 200. When the lifting roller 211 rotates to a high position along the upper surface of the lifting cam component, the lifting roller 211 can drive the lifting mounting frame 212 and the lifting seat 213 to move upward, thereby causing the lifting seat 213 to push the battery steel shell 200 into the snap-fit ​​groove 2243, achieving axial positioning of the battery steel shell 200.

[0073] Now combined Figure 6 The specific structure of the grooving mechanism 4 is described below, such as... Figure 6 As shown, the grooving mechanism 4 includes a grooving roller 41, a rotating arm 42, a connecting shaft 43, and a grooving assembly 44. The grooving roller 41 rolls against the wheel edge of the push cam 62. The grooving roller 41 is rotatably mounted on the rotating arm 42, and the rotating arm 42 is fixed on the connecting shaft 43. The connecting shaft 43 is rotatably mounted on the mounting plate 51. The grooving assembly 44 is fixed on the connecting shaft 43. When the grooving roller 41 rotates relative to the push cam 62 to the high position of the push cam 62, the grooving roller 41 drives the rotating arm 42 and the connecting shaft 43 to rotate relative to the mounting plate 51, thereby driving the grooving assembly 44 to rotate towards the battery steel shell 200, realizing the feeding of the grooving assembly 44 towards the battery steel shell 200, and ensuring that the grooving assembly 44 performs grooving processing on the battery steel shell 200.

[0074] Specifically, the grooving assembly 44 includes a grooving arm 441, a hob 442, and a motor (not shown in the figure). The grooving arm 441 is connected to the connecting shaft 43, and the motor is mounted on the grooving arm 441. The output end of the motor is connected to the hob 442, and the motor drives the hob 442 to rotate at high speed, thereby ensuring that the hob 442 can perform grooving processing on the battery steel shell 200 when it is close to the battery steel shell 200.

[0075] In this embodiment, the battery grooving device 100 further includes a reset mechanism, which comprises independently disposed first reset component 71, second reset component 72, and third reset component 73, wherein, as shown in the figure... Figure 2 As shown, the lifting assembly 21 moves downward to reset under the action of the first reset assembly 71, and the pressing assembly 22 moves upward to reset under the action of the second reset assembly 72, as... Figure 6 As shown, the grooving mechanism 4 rotates and resets in a direction away from the battery steel casing 200 under the action of the third reset component 73. Specifically, as... Figure 2As shown, both the first reset assembly 71 and the second reset assembly 72 are tension springs. Tension springs have the advantages of high elasticity and reliable operation. The two ends of the first reset assembly 71 are connected to the mounting plate 51 and the lifting mounting bracket 212, respectively. When the lifting roller 211 rotates to a high position relative to the upper surface of the lifting cam, the first reset assembly 71 is compressed. When the lifting roller 211 continues to rotate away from the high position relative to the upper surface of the lifting cam, the lifting assembly 21 moves downwards to reset under the elastic restoring force of the first reset assembly 71. The two ends of the second reset assembly 72 are connected to the mounting plate 51 and the pressing mounting bracket 222, respectively. When the pressing roller 221 rotates to a high position relative to the lower surface of the pressing cam, the second reset assembly 72 is compressed. When the pressing roller 221 continues to rotate away from the high position relative to the lower surface of the pressing cam, the pressing assembly 22 moves upwards to reset under the elastic restoring force of the second reset assembly 72. Furthermore, as... Figure 6 As shown, the third reset component 73 is also a tension spring. The two ends of the third reset component 73 are connected to the mounting plate 51 and the rotating arm 42 respectively. When the grooving roller 41 rotates to the high position relative to the wheel edge of the push cam 62, the third reset component 73 is compressed. When the grooving roller 41 continues to rotate away from the high position relative to the wheel edge of the push cam 62, the grooving mechanism 4 rotates and resets in the direction away from the battery steel shell 200 under the action of the elastic restoring force of the third reset component 73.

[0076] To facilitate understanding of the battery grooving device 100 disclosed in this embodiment, it is now combined with... Figures 1-6 The specific working process of the battery grooving device 100 is explained below:

[0077] The rotary motor 631 drives the driving wheel 633 and the driven wheel 634 to rotate. The driven wheel 634 drives the rotating shaft assembly 61 to rotate, so that the rotating shaft assembly 61 synchronously drives the mounting mechanism 5, the grooving mechanism 4, the lifting assembly 21, and the pressing assembly 22 to rotate relative to the pressing drive 23, the shaping drive 24, the lifting drive 25, and the pushing cam 62. At this time, under the action of the pressing drive 23, the pressing assembly 22 causes the pressing roller 2211 to drive the pressure head body 2241 to move down a certain distance. Simultaneously, the lifting roller 211 moves down the lifting cam. Under the action of the lifting seat 213, the battery steel shell 200 is pushed into the snap-fit ​​groove 2243 of the pressing component 22. Simultaneously, the grooving roller 41 drives the hob 442 to feed into the groove closer to the battery steel shell 200 under the action of the pushing cam 62. Simultaneously, the limiting roller 323 abuts against the other side of the battery steel shell 200 and forms a reaction force with the hob 442. Simultaneously, the rotating mechanism 1 drives the snap-fit ​​groove 2243 to rotate and synchronously drives the battery steel shell 200 to rotate, thereby realizing the grooving process of the battery steel shell 200.

[0078] Next, the rotating shaft assembly 61 continues to drive the mounting mechanism 5, the grooving mechanism 4, the lifting assembly 21 and the pressing assembly 22 to rotate relative to the pressing drive 23, the shaping drive 24, the lifting drive 25 and the pushing cam 62. At this time, the shaping roller 2212 moves downward under the action of the shaping drive 24, thereby driving the pressing head 224 to press down on the battery steel shell 200, thereby realizing the shaping operation of the grooved battery steel shell 200.

[0079] Then, the rotating shaft assembly 61 continues to drive the mounting mechanism 5, the grooving mechanism 4, the lifting assembly 21 and the pressing assembly 22 to rotate relative to the pressing drive 23, the shaping drive 24, the lifting drive 25 and the pushing cam 62. At this time, the grooving mechanism 4 moves away from the high position of the pushing cam 62 and is reset under the action of the third reset assembly 73. The lifting assembly 21 moves away from the high position of the lifting cam and moves downward to reset under the action of the first reset assembly 71. Simultaneously, the pressing roller 2211 abuts against the unloading point 231 at the high position of the pressing drive 23, so that the pressing head 224 continues to press down on the battery steel shell 200, so that the battery steel shell 200 is disengaged from the snap-fit ​​of the snap-fit ​​groove 2243 and resets into the guide claw 52.

[0080] Finally, the pressing roller 2211 and the shaping roller 2212 move away from the high position of the corresponding cam and move upward to reset under the action of the second reset component 72, completing the entire processing process so that the next round of repeated operation can be carried out.
