[0024] Referring to Figures 1 and 2, the shell insertion device 100 of the embodiment of the present application includes a bracket 10, a track plate 20, a guide plate 30, a first clamping member 40 and a second clamping member 50. The track plate 20 is fixedly mounted on the bracket 10, and a first track groove 21 and a second track groove 22 extending along the second direction are provided on a side surface of the track plate 20 in the first direction. The guide plate 30 is slidably mounted on the bracket 10, and the guide plate 30 is located on one side of the track plate 20 in the first direction. The guide plate 30 can slide in the second direction, and a linear guide rail 31 along the third direction is provided on the guide plate 30. The first clamping member 40 includes a first clamping portion 41 and a first guide portion 42 connected (as shown in Figure 5). The first clamping portion 41 is slidably provided on the linear guide rail 31, and the first guide portion 42 extends into the first track groove 21. The second clamping member 50 includes a second clamping portion 51 and a second guide portion 52 (as shown in FIG5 ) connected to each other. The second clamping portion 51 is slidably disposed on the linear guide rail 31, and the second guide portion 52 extends into the second track groove 22. When the guide plate 30 drives the first clamping member 40 and the second clamping member 50 to slide in the second direction, the first clamping member 40 and the second clamping member 50 slide along the linear guide rail 31 under the influence of the first track groove 21 and the second track groove 22, thereby moving closer to or farther away from each other.

[0025] In the shell insertion device 100 of the embodiment of the present application, when the guide plate 30 drives the first clamping member 40 and the second clamping member 50 to slide along the second direction, the first clamping member 40 and the second clamping member 50 slide along the linear guide rail 31 under the action of the first track groove 21 and the second track groove 22 so as to approach or move away, so that the first shell insertion object (such as the battery cell) clamped by the first clamping member 40 cooperates with the first shell insertion object (such as the shell 200) clamped by the second clamping member 50 to complete the shell insertion operation. The shell insertion device 100 can use the movement trajectory of the first clamping member 40 and the second clamping member 50 to complete the shell insertion operation, realize automated operation, and have a high shell insertion efficiency. In addition, the shell insertion device 100 has a simple structure and a small space volume, which saves production costs and reduces the space occupied in the workshop.

[0026] Specifically, the bracket 10 can play the role of installation, support and protection for the track plate 20, the guide plate 30, and the transmission assembly 60 described later. The bracket 10 may include a plurality of support parts. As shown in Figure 2, the bracket 10 includes four support parts connected end to end in sequence, so that the structure of the bracket 10 is relatively stable. The four support parts are the first support part 11, the second support part 12, the third support part 13 and the fourth support part 14. The first support part 11 and the third support part 13 are arranged parallel to each other. The second support part 12 and the fourth support part 14 are arranged parallel to each other. The extension direction of the first support part 11 and the third support part 13 is the second direction, and the extension direction of the second support part 12 and the fourth support part 14 is the third direction. The second direction is also the length direction of the shell insertion device 100 (the left-right direction in Figure 1), and the third direction is also the height direction of the shell insertion device 100 (the up-down direction in Figure 1).

[0027] The track pad 20 is fixedly mounted on the bracket 10, for example, fixedly mounted between the first support portion 11, the second support portion 12, the third support portion 13 and the fourth support portion 14. The track pad 20 can be a square structure, such as a rectangular structure or a square structure. The track pad 20 is provided with a first track groove 21 and a second track groove 22 extending along the second direction on a side surface in the first direction. The first direction is also the thickness direction of the shell insertion device 100 (the direction perpendicular to the paper in Figure 1). The track pad 20 can be a whole track pad 20, and the first track groove 21 and the second track groove 22, as well as the third track groove 23 and the fourth track groove 24 described below are all formed in the track pad 20; or, the track pad 20 may include four plates arranged along the third direction, and the first track groove 21 and the second track groove 22, as well as the third track groove 23 and the fourth track groove 24 described below are respectively formed in the corresponding four plates. The extending direction of the first track groove 21 and the second track groove 22 is the second direction. The tracks of the first track groove 21 and the second track groove 22 can be straight lines, curves, or a combination of straight lines and curves, which is not limited here.

[0028] The guide plate 30 is slidably mounted on the bracket 10. The guide plate 30 is located on one side of the trackpad 20 in the first direction and is slidable in the second direction. Both the first support portion 11 and the third support portion 13 are provided with sliding rails 15 extending in the second direction, allowing the upper and lower ends of the guide plate 30 to slide along the sliding rails 15 on the first support portion 11 and the third support portion 13, respectively, thereby enabling the guide plate 30 to slide in the second direction. The guide plate 30 is also provided with a linear guide 31 extending in the third direction.

[0029] The first clamping member 40 includes a first clamping portion 41 and a first guide portion 42 connected to each other. The first clamping portion 41 is slidably disposed on the linear guide rail 31, and the first guide portion 42 extends into the first track groove 21. The first clamping portion 41 is at least partially located on the side of the guide rail plate 30 facing away from the track plate 20, and the first guide portion 42 is located on the side of the guide rail plate 30 facing the track plate 20. The first guide portion 42 can be a cam bearing follower. The second clamping member 50 includes a second clamping portion 51 and a second guide portion 52 connected to each other, the second clamping portion 51 is slidably disposed on the linear guide rail 31, and the second guide portion 52 extends into the first track groove 21. The second clamping portion 51 is at least partially located on the side of the guide rail plate 30 facing away from the track plate 20, and the second guide portion 52 is located on the side of the guide rail plate 30 facing the track plate 20. The second guide portion 52 can be a cam bearing follower.

[0030] When the guide rail plate 30 drives the first clamping member 40 and the second clamping member 50 to slide along the second direction, the first clamping member 40 and the second clamping member 50 slide along the linear guide rail 31 under the action of the first track groove 21 and the second track groove 22, thereby approaching or moving away. The specific process can be as follows: the guide rail plate 30 slides along the second direction on the sliding guide rail 15, driving the first clamping member 40 and the second clamping member 50 to slide along the second direction. At this time, the first guide portion 42 and the second guide portion 52 slide along the first track groove 21 and the second track groove 22 respectively. The first clamping member 41 fixedly connected to the first guide portion 42 and the second clamping member 51 fixedly connected to the second guide portion 52 then move relative to each other along the third direction on the linear guide rail 31, thereby approaching or moving away from each other. The first shell object (e.g., battery cell) clamped by the first clamping member 41 and the first shell object (e.g., shell 200) clamped by the second clamping member 51 also move closer to or away from each other accordingly, thereby cooperating to achieve the shell insertion operation.

[0031] Referring to Figures 1 to 3 , in certain embodiments, the shell insertion device 100 further includes a transmission assembly 60. The transmission assembly 60 includes an active mounting base 61, a passive mounting base 62, a transmission belt 63, and an actuator 64. The active mounting base 61 and the passive mounting base 62 are both fixedly mounted on the bracket 10. The actuator 64 is disposed on the active mounting base 61 and is configured to drive the transmission belt 63 to move between the active mounting base 61 and the passive mounting base 62 in the second direction. A fixed plate 32 is disposed on the side of the guide plate 30 facing away from the linear guide rail 31, and the transmission belt 63 is fixedly connected to the fixed plate 32.

[0032] In this way, the actuating member 64 can drive the transmission belt 63 to move along the second direction between the active fixing seat 61 and the driven fixing seat 62, so as to drive the guide plate 30 to slide along the second direction through the fixing plate 32, thereby realizing the subsequent automatic shell insertion operation.

[0033] Specifically, the active fixing seat 61 can be installed on one of the aforementioned second support part 12 and the fourth support part 14, and the passive fixing seat 62 is installed on the other of the aforementioned second support part 12 and the fourth support part 14. As shown in the example of Figure 2, the active fixing seat 61 is installed on the second support part 12, and the passive fixing seat 62 is installed on the fourth support part 14. The transmission belt 63 can be a synchronous belt (such as a belt), and the transmission belt 63 is arranged between the active fixing seat 61 and the passive fixing seat 62. The actuator 64 is arranged on the active fixing seat 61. The actuator 64 can be a handwheel, and the actuator 64 can be pushed by the operator without the need for an electric control element. The rotation of the handwheel can drive the transmission belt 63 to move between the active fixing seat 61 and the passive fixing seat 62.

[0034] The fixing plate 32 can be disposed on the side of the guide rail plate 30 facing the track plate 20 and fixedly connected to the transmission belt 63. For example, the fixing plate 32 clamps the transmission belt 63, so that when the transmission belt 63 moves in the second direction between the active fixing seat 61 and the driven fixing seat 62, the fixing plate 32 drives the guide rail plate 30 in the second direction. A clearance space 33 (as shown in FIG. 3 ) can also be formed on the side of the guide rail plate 30 facing the track plate 20 at a location corresponding to the transmission belt 63 to prevent movement of the transmission belt 63 in the second direction and reduce the overall volume of the shell insertion device 100. The fixing plate 32 can be disposed in this clearance space 33.

[0035] In the embodiment of the present application, the transmission assembly 60 can be mounted on the track plate 20 along the second direction, and the guide rail plate 30 can be mounted on the transmission assembly 60 along the third direction, so that the overall structure of the shell entry device 100 is compact and the spatial volume is small, and the movement of the transmission belt 63 along the second direction will not interfere with the movement of the first clamping member 40 and the second clamping member 50 on the guide rail plate 30 along the third direction.

[0036] Please refer to Figures 1 and 2. In some embodiments, the track plate 20 is further provided with a third track groove 23 extending along the second direction on a side surface in the first direction. The shell insertion device 100 also includes a push rod assembly 70. The push rod assembly 70 is slidably disposed on the linear guide rail 31, and the push rod assembly 70 is located on the side of the first clamping member 40 away from the second clamping member 50. The push rod assembly 70 includes a third guide portion 71 (as shown in Figure 5), and the third guide portion 71 extends into the third track groove 23. When the guide plate 30 drives the push rod assembly 70 and the first clamping member 40 to slide along the second direction, the push rod assembly 70 and the first clamping member 40 slide along the linear guide rail 31 under the action of the third track groove 23 and the first track groove 21, thereby approaching or moving away.

[0037] In this way, when the battery cell clamped by the first clamping member 40 cooperates with the shell 200 clamped by the second clamping member 50 to perform the shell insertion operation, the push rod assembly 70 can apply a thrust along the second direction to assist the battery cell to enter the shell 200, thereby realizing the shell insertion operation between the battery cell and the shell 200.

[0038] Specifically, the third track groove 23 is located on the side of the first track groove 21 away from the second track groove 22. The extension direction of the third track groove 23 is the second direction. The track of the third track groove 23 can be a straight line, a curve, or a combination of a straight line and a curve, etc., which is not limited here. On the guide plate 30, along the second direction are: the push rod assembly 70, the first clamping member 40, and the second clamping member 50. The battery cell is clamped in the first clamping member 40, and the housing 200 is clamped in the second clamping member 50. When the push rod assembly 70 moves along the second direction, it can apply a thrust to the battery cell on the side of the guide plate 30 where the linear guide 31 is provided, and apply a thrust to the first clamping part 41 on the side of the guide plate 30 facing away from the linear guide 31.

[0039] Referring to Figures 1 and 2 , in certain embodiments, the push rod assembly 70 includes a first push member 72 located on the side of the guide plate 30 where the linear guide 31 is located. The first clamping portion 41 includes a clamping claw 411 (as shown in Figure 4 ) located on the side of the guide plate 30 where the linear guide 31 is located. When the guide plate 30 drives the first clamping member 40 to slide in the second direction, the first push member 72 applies a thrust toward the battery cell clamped by the clamping claw 411.

[0040] In this way, when performing the shell insertion operation, the first push member 72 in the push rod assembly 70 can apply a pushing force to the battery cell along the second direction to assist the battery cell in entering the shell 200 , thereby achieving the shell insertion operation between the battery cell and the shell 200 .

[0041] Specifically, when the battery cell and the housing 200 are inserted into the housing, the first push member 72 of the push rod assembly 70 applies a pushing force behind the battery cell to move the battery cell into the housing 200. The first push member 72 is, for example, a push rod structure. The extending direction of the first push member 72 is consistent with the second direction, so as to facilitate applying a pushing force toward the battery cell.

[0042] 2 , in some embodiments, the push rod assembly 70 further includes a pressure detecting member 74 connected to the first push member 72. The pressure detecting member 74 is used to detect the pressure value borne by the first push member 72 in the second direction.

[0043] In this way, the pressure value that the first push member 72 is subjected to in the second direction can be detected by the pressure detection member 74. If the battery cell is stuck during the shell insertion process, or other problems cause the pressure of the first push member 72 to be too high, it can be detected in time by the pressure detection member 74, and an alarm can be issued in time as needed to prompt the operator to check for abnormalities.

[0044] Specifically, the pressure detection member 74 can be a pressure sensor. The pressure detection member 74 can be disposed at an end of the first push member 72 away from the first clamping member 40 to detect the pressure applied to the first push member 72 in the second direction when the first push member 72 is subjected to the reaction force of the battery cell. Of course, the pressure detection member 74 can also be disposed at other locations on the first push member 72. Simply by converting the real-time pressure data detected by the pressure detection member 74, the pressure applied to the first push member 72 in the second direction can be determined.

[0045] As shown in FIG2 , the shell insertion device 100 may further include a pressure display member 76 connected to the pressure detection member 74, such as a pressure display instrument, so that when the pressure value detected by the pressure detection member 74 is too large (i.e., the pressure borne by the first push member 72 is too large), an alarm can be promptly issued through the display instrument to prompt the operator to check for abnormalities.

[0046] 2 and 4 , in some embodiments, the push rod assembly 70 further includes an elastic member 75 connected to the first push member 72. The first push member 72 includes a mounting end 721 and an operating end 722, the operating end 722 being used to apply a thrust to the battery cell, and the elastic member 75 is located at the mounting end 721.

[0047] In this way, when the first pushing member 72 applies a thrust to the battery cell along the second direction, the battery cell reacts to the first pushing member 72, and the elastic action of the elastic member 75 can buffer and protect the battery cell, thereby preventing the thrust from suddenly increasing and causing damage to the battery cell.

[0048] Specifically, the elastic member 75 is, for example, a spring. The first push member 72 includes a mounting end 721 and an active end 722. The mounting end 721 is opposite the active end 722, and the active end 722 faces the battery cell. In the initial state, the active end 722 is spaced apart from the battery cell. The elastic member 75 is disposed at the mounting end 721. When the first push member 72 applies a thrust to the battery cell, the battery cell reacts against the first push member 72, which in turn acts on the elastic member 75. The reaction force of the elastic member 75 can buffer and protect the battery cell.

[0049] Referring to Figures 2 and 5 , in some embodiments, the push rod assembly 70 further includes a second push member 73, which is located on a side of the guide plate 30 facing away from the linear guide rail 31. The first clamping portion 41 further includes a back portion 412 connected to the clamping jaw 411, which is located on a side of the guide plate 30 facing away from the linear guide rail 31. When the guide plate 30 drives the first clamping member 40 to slide in the second direction, the second push member 73 applies a pushing force toward the back portion 412 to release the clamping jaw 411.

[0050] In this way, when performing the shell insertion operation, the second push member 73 in the push rod assembly 70 can apply a push force to the back 412 along the second direction to loosen the clamping claw 411, so that the battery cell loses the clamping force of the clamping claw 411 and moves to the shell 200, thereby realizing the shell insertion operation between the battery cell and the shell 200.

[0051] Specifically, the aforementioned first push member 72 is disposed on the side of the guide plate 30 opposite the track pad 20 (as shown in FIG4 ), while the second push member 73 of the present embodiment is disposed on the side of the guide plate 30 opposite the track pad 20 (as shown in FIG5 ). When the battery cell and the housing 200 cooperate to perform the housing insertion operation, the second push member 73 of the push rod assembly 70 applies a pushing force along the second direction to the first clamping portion 41, specifically acting on the back portion 412 of the first clamping portion 41, thereby loosening the first clamping portion 41, causing the clamping claw 411 of the first clamping portion 41 to release the battery cell, thereby losing the clamping force of the first clamping portion 41 and being able to be smoothly inserted into the housing.

[0052] Please refer to Figures 1 and 2. In some embodiments, the track plate 20 is further provided with a fourth track groove 24 extending along the second direction on a side surface in the first direction. The shell insertion device 100 also includes an ejector assembly 80. The ejector assembly 80 is slidably disposed on the linear guide rail 31, and the ejector assembly 80 is located on the side of the second clamping member 50 away from the first clamping member 40. The ejector assembly 80 includes a fourth guide portion 81 (as shown in Figure 5), and the fourth guide portion 81 extends into the fourth track groove 24. When the guide plate 30 drives the ejector assembly 80 and the second clamping member 50 to slide along the second direction, the ejector assembly 80 and the second clamping member 50 slide along the linear guide rail 31 under the action of the fourth track groove 24 and the second track groove 22, thereby approaching or moving away.

[0053] In this way, when the battery cell clamped by the first clamping member 40 cooperates with the shell 200 clamped by the second clamping member 50 to perform the shell insertion operation, the battery cell can be guided along the second direction by the ejector pin assembly 80 so that the pole of the battery cell is consistent with the central axis of the shell 200, thereby ensuring the concentricity between the pole of the battery cell and the shell 200, and improving the accuracy of the shell insertion operation and the production qualification rate.

[0054] Specifically, the fourth track groove 24 is located on the side of the second track groove 22 away from the first track groove 21. The extension direction of the fourth track groove 24 is the second direction. The track of the fourth track groove 24 can be a straight line, a curve, or a combination of a straight line and a curve, etc., which is not limited here. On the guide plate 30, along the second direction are: a first clamping member 40, a second clamping member 50, and an ejector pin assembly 80. The battery cell is clamped by the first clamping member 40, the shell 200 is clamped by the second clamping member 50, and the ejector pin assembly 80 includes a guide ejector pin 82. When the battery cell and the shell 200 cooperate to perform the shell insertion operation, the guide ejector pin 82 extends into the shell 200 from the rear of the shell 200 and supports the pole of the battery cell to play a buffering and guiding role during the shell insertion process, so that the pole of the battery cell is consistent with the central axis of the shell 200. It should be noted that the position of the guide pin 82 can be pre-set to align with the central axis of the housing 200. This allows the guide pin 82 to simply support the battery cell's pole and guide it into the housing during insertion, aligning the pole with the central axis of the housing 200. In the embodiments of the present application, the battery cell is, for example, a bare cell. The housing 200 is, for example, a steel housing, and the central axis of the housing 200 specifically refers to the central axis of the inner hole of the housing 200.

[0055] Please refer to Figures 2 and 4. In some embodiments, the first clamping member 40 also includes a first control part 43 connected to the first clamping portion 41, and the first control part 43 is used to control the clamping state of the first clamping portion 41; and / or the second clamping member 50 also includes a second control part 53 connected to the second clamping portion 51, and the second control part 53 is used to control the clamping state of the second clamping portion 51.

[0056] Thus, when the shell insertion operation is required, the clamping state of the first clamping portion 41 can be controlled by the first control unit 43. For example, the first clamping portion 41 can be first opened by the first control unit 43, and then the battery cell can be placed in the first clamping portion 41. The first control unit 43 can then be used to control the first clamping portion 41 to clamp the battery cell, so that the subsequent shell insertion operation can be performed. Similarly, when the shell insertion operation is required, the clamping state of the second clamping portion 51 can be controlled by the second control unit 53. For example, the second clamping portion 51 can be first opened by the second control unit 53, and then the shell 200 can be placed in the second clamping portion 51. The second control unit 53 can then be used to control the second clamping portion 51 to clamp the shell 200, so that the subsequent shell insertion operation can be performed.

[0057] Specifically, the first control part 43 can be a spring handle. The first control part 43 is used to control the clamping state of the first clamping part 41, for example, to control the first clamping part 41 to be in a loose state or a clamped state. When a pulling force is applied to the first control part 43, the first clamping part 41 switches from a clamped state to a loose state; when the pulling force applied to the first control part 43 is released, the first clamping part 41 returns to a clamped state. In specific applications, when a shell insertion operation is required, the operator can apply a pulling force to the first control part 43 to switch the first clamping part 41 from a clamped state to a loose state, and then place the battery cell into the first clamping part 41, and then release the pulling force applied to the first control part 43 to restore the first clamping part 41 to a clamped state. The first clamping part 41 clamps the battery cell for subsequent shell insertion operations.

[0058] The second control part 53 can be a spring handle. The second control part 53 is used to control the clamping state of the second clamping part 51, for example, to control the second clamping part 51 to be in a loose state or a clamped state. When a pulling force is applied to the second control part 53, the second clamping part 51 switches from a clamped state to a loose state; when the pulling force applied to the second control part 53 is released, the second clamping part 51 returns to a clamped state. In specific applications, when a shell insertion operation is required, the operator can apply a pulling force to the second control part 53 to switch the second clamping part 51 from a clamped state to a loose state, and then place the shell 200 into the second clamping part 51, and then release the pulling force applied to the second control part 53 to restore the second clamping part 51 to a clamped state. The second clamping part 51 clamps the shell 200 for subsequent shell insertion operations.

[0059] 1 and 2 , in some embodiments, the shell insertion device 100 further includes a third clamping member 90 . The third clamping member 90 is located between the first clamping member 40 and the second clamping member 50 , and is fixedly mounted on the guide rail plate 30 .

[0060] Thus, during the insertion operation, the third clamping member 90 supports the insertion of the battery cell into the housing 200. For example, the housing 200 is first moved into the third clamping member 90, and then the battery cell is moved into the housing 200, thereby completing the insertion operation. Because the third clamping member 90 is fixed to the guide plate 30, the insertion operation is relatively smooth under the clamping of the third clamping member 90, and is less likely to deviate.

[0061] Specifically, when performing the shell insertion operation, the second clamping member 50 moves along the second direction (specifically, from the second clamping member 50 toward the first clamping member 40, that is, from bottom to top in Figure 1), so that the shell 200 rises to the third clamping member 90, and the third clamping member 90 clamps the shell 200. The first clamping member 40 then moves along the second direction (specifically, from the first clamping member 40 toward the second clamping member 50, that is, from top to bottom in Figure 1), so that the battery cell moves downward into the shell 200, thereby completing the shell insertion operation.

[0062] 6 , in some embodiments, along the second direction, the distance between the first track groove 21 and the second track groove 22 in the third direction first gradually decreases and then gradually increases. The process of gradually decreasing and increasing the distance may also include a process in which the distance remains constant.

[0063] In this way, the battery cell clamped by the first clamping member 40 and the shell 200 clamped by the second clamping member 50 gradually approach and then gradually move away along the linear guide rail 31 under the action of the first track groove 21 and the second track groove 22, so as to complete the shell insertion operation between the battery cell and the shell 200 and the return operation after the shell insertion.

[0064] 6 , in some embodiments, along the second direction, the distance between the third track groove 23 and the first track groove 21 in the third direction gradually decreases. After the distance gradually decreases, a process of maintaining the distance constant may also be included.

[0065] In this way, the battery cell clamped by the push rod assembly 70 and the first clamping member 40 gradually approaches along the linear guide rail 31 under the action of the third track groove 23 and the first track groove 21, so as to apply thrust to the battery cell through the push rod assembly 70 to assist the battery cell to enter the shell 200.

[0066] 6 , in some embodiments, along the second direction, the distance between the fourth track groove 24 and the second track groove 22 in the third direction first gradually decreases and then gradually increases. The process of gradually decreasing and increasing the distance may also include a process in which the distance remains constant.

[0067] In this way, the housing 200 clamped by the ejector assembly 80 and the second clamping member 50 gradually approaches and then gradually moves away along the linear guide rail 31 under the action of the fourth track groove 24 and the second track groove 22, thereby guiding the insertion of the battery cell into the housing 200 and allowing the ejector to withdraw after the insertion, completing the entire insertion process.

[0068] The following describes the operating process of the shell insertion device 100 according to an embodiment of the present application, with reference to Figure 6 . As shown in Figure 6 , the shell insertion operation can include four stages. In the first stage, the distance between the first and second track grooves 21 and 22 gradually decreases, and the distance between the fourth track groove 24 and the second track groove 22 gradually decreases. Accordingly, the shell 200 moves from bottom to top into the third clamping member 90, and the guide pin 82 moves from bottom to top into the shell 200. In the second stage, the distance between the third track groove 23 and the first track groove 21 gradually decreases, the distance between the first track groove 21 and the second track groove 22 gradually decreases, and the distance between the fourth track groove 24 and the second track groove 22 gradually decreases. Correspondingly, the position of the shell 200 in the third clamping member 90 remains unchanged, and the second push member 73 of the push rod assembly 70 applies a thrust to the first clamping member 40 to make the first clamping member 40 release the battery cell. The first push member 72 of the push rod assembly 70 applies a thrust downward to the battery cell to make the battery cell enter the shell 200. At the same time, the guide pin 82 will continue to move upward to support the pole of the battery cell to guide the battery cell so that the pole of the battery cell is consistent with the central axis of the shell 200. In the third stage, the distance between the third track groove 23 and the first track groove 21 gradually decreases, and the distance between the fourth track groove 24 and the second track groove 22 gradually increases. Correspondingly, the push rod assembly 70 continues to push the battery cell downward, allowing the battery cell to fully enter the housing 200. At the same time, the guide ejector pin 82 begins to move downward and exit the housing 200. In the fourth stage, the distance between the second track groove 22 and the first track groove 21 gradually increases. Correspondingly, the housing 200 moves downward and back into place, completing the entire housing insertion operation.
