Description

Technical Field

[0001] This application relates to the technical field of battery assembly, and particularly to a case loading device. Background Art

[0002] During the battery production process, after the battery cells are processed, they need to be loaded into cases to effectively provide insulation protection for the battery cells. For mass production, the battery cells are usually loaded into cases in a mechanized manner, which has a relatively complex structure and high cost and is not suitable for small batch production. Therefore, most manufacturers use manual case loading for small batch production, but manual case loading has the problem of low efficiency. Summary of the Invention

[0003] Embodiments of this application provide a case loading device to solve at least one of the above technical problems.

[0004] The case loading device according to the embodiments of this application includes a bracket, a track plate, a guide rail plate, a first clamping member, and a second clamping member. The track plate is fixedly installed on the bracket. On one surface of the track plate in a first direction, there are provided a first track groove and a second track groove extending along a second direction. The guide rail plate is slidably installed on the bracket. The guide rail plate is located on one side of the track plate in the first direction. The guide rail plate can slide in the second direction. A linear guide rail is provided on the guide rail plate along a third direction. The first clamping member includes a connected first clamping part and a first guiding part. The first clamping part is slidably disposed on the linear guide rail, and the first guiding part extends into the first track groove. The second clamping member includes a connected second clamping part and a second guiding part. The second clamping part is slidably disposed on the linear guide rail, and the second guiding part extends into the second track groove. When the guide rail plate drives the first clamping member and the second clamping member to slide along the second direction, the first clamping member and the second clamping member slide along the linear guide rail under the action of the first track groove and the second track groove so as to approach or separate from each other.

[0005] In the case loading device according to the embodiments of this application, when the guide rail plate drives the first clamping member and the second clamping member to slide along the second direction, the first clamping member and the second clamping member slide along the linear guide rail under the action of the first track groove and the second track groove so as to approach or separate from each other, so that the first case loading object (such as a battery cell) clamped by the first clamping member cooperates with the first case loading object (such as a case) clamped by the second clamping member to complete the case loading operation. The case loading device can utilize the movement trajectories of the first clamping member and the second clamping member to complete the case loading operation, realizing automated operation and having a relatively high case loading efficiency. In addition, the case loading device has a simple structure, a small spatial volume, saving production costs and reducing the space occupied in the workshop.

[0006] In some embodiments, the shell-inserting device further includes a transmission assembly. The transmission assembly includes a driving fixed seat, a driven fixed seat, a transmission belt, and an actuating member. The driving fixed seat and the driven fixed seat are both fixedly installed on the bracket, and the actuating member is disposed on the driving fixed seat and is used to drive the transmission belt to move in a second direction between the driving fixed seat and the driven fixed seat. A fixing plate is provided on a side of the guide rail plate facing away from the linear guide rail, and the transmission belt is fixedly connected to the fixing plate.

[0007] In this way, the actuating member can drive the transmission belt to move in the second direction between the driving fixed seat and the driven fixed seat, so as to drive the guide rail plate to slide in the second direction through the fixing plate, thereby realizing subsequent automatic shell-inserting operations.

[0008] In some embodiments, a third track groove extending in the second direction is further provided on a surface of the track plate on one side in the first direction. The shell-inserting device further includes a push rod assembly. The push rod assembly is slidably disposed on the linear guide rail, and the push rod assembly is located on a side of the first clamping member away from the second clamping member. The push rod assembly includes a third guiding portion, and the third guiding portion extends into the third track groove. When the guide rail plate drives the push rod assembly and the first clamping member to slide in the second direction, the push rod assembly and the first clamping member slide along the linear guide rail to approach or separate under the action of the third track groove and the first track groove.

[0009] In this way, when the battery cell clamped by the first clamping member cooperates with the housing clamped by the second clamping member for shell-inserting operation, a thrust can be applied in the second direction through the push rod assembly to assist the battery cell to enter the housing, thereby realizing the shell-inserting operation between the battery cell and the housing.

[0010] In some embodiments, the push rod assembly includes a first pushing member, and the first pushing member is located on a side of the guide rail plate provided with the linear guide rail. The first clamping portion includes a clamping jaw, and the clamping jaw is located on a side of the guide rail plate provided with the linear guide rail. When the guide rail plate drives the first clamping member to slide in the second direction, the first pushing member applies a thrust to the battery cell clamped by the clamping jaw.

[0011] In this way, during the shell-inserting operation, the first pushing member in the push rod assembly can apply a thrust to the battery cell in the second direction to assist the battery cell to enter the housing, thereby realizing the shell-inserting operation between the battery cell and the housing.

[0012] In some embodiments, the push rod assembly further includes a pressure detection member connected to the first pushing member. The pressure detection member is used to detect the pressure value borne by the first pushing member in the second direction.

[0013] In this way, the pressure value borne by the first pusher in the second direction can be detected by the pressure detection component. If the battery cell gets stuck during the shell insertion process or other problems cause excessive pressure on the first pusher, it can be detected in time by the pressure detection component, and an alarm can also be given in time according to the need to prompt the operator to check for abnormalities.

[0014] In some embodiments, the push rod assembly further includes an elastic member connected to the first pusher. The first pusher includes an opposite mounting end and an acting end, the acting end is used to apply a thrust to the battery cell, and the elastic member is located at the mounting end.

[0015] In this way, when the first pusher applies a thrust to the battery cell in the second direction, the battery cell reacts on the first pusher, and the elastic action of the elastic member can play a buffering and protective role on the battery cell to avoid damage to the battery cell caused by a sudden increase in the thrust.

[0016] In some embodiments, the push rod assembly further includes a second pusher, and the second pusher is located on the side of the guide rail plate facing away from the linear guide rail. The first clamping portion further includes a back connected to the clamping jaw, and the back is located on the side of the guide rail plate facing away from the linear guide rail. When the guide rail plate drives the first clamping member to slide along the second direction, the second pusher applies a thrust towards the back to loosen the clamping jaw.

[0017] In this way, during the shell insertion operation, the second pusher in the push rod assembly can apply a thrust along the second direction to the back to loosen the clamping jaw, so that the battery cell loses the clamping force of the clamping jaw and moves to the shell, realizing the shell insertion operation between the battery cell and the shell.

[0018] In some embodiments, a fourth track groove extending along the second direction is further provided on one surface of the track plate in the first direction. The shell insertion device further includes a thimble assembly. The thimble assembly is slidably arranged on the linear guide rail, and the thimble assembly is located on the side of the second clamping member away from the first clamping member. The thimble assembly includes a fourth guiding portion, and the fourth guiding portion extends into the fourth track groove. When the guide rail plate drives the thimble assembly and the second clamping member to slide along the second direction, the thimble assembly and the second clamping member slide along the linear guide rail to approach or separate under the action of the fourth track groove and the second track groove.

[0019] In this way, when the battery cell clamped by the first clamping member cooperates with the shell clamped by the second clamping member for the shell insertion operation, the thimble assembly can guide the battery cell along the second direction to make the pole column of the battery cell coincide with the central axis of the shell, thereby ensuring the concentricity between the pole column of the battery cell and the shell and improving the accuracy of the shell insertion operation and the production qualification rate.

[0020] In some embodiments, the first clamping member further includes a first control portion connected to the first clamping portion, and the first control portion is configured to control the clamping state of the first clamping portion; and / or the second clamping member further includes a second control portion connected to the second clamping portion, and the second control portion is configured to control the clamping state of the second clamping portion.

[0021] Thus, when the case insertion operation needs to be performed, the clamping state of the first clamping portion can be controlled by the first control portion. For example, first, the first clamping portion is opened by the first control portion, then the battery cell is placed in the first clamping portion, and then the first clamping portion is controlled by the first control portion to clamp the battery cell, so as to perform the subsequent case insertion operation.

[0022] Similarly, when the case insertion operation needs to be performed, the clamping state of the second clamping portion can be controlled by the second control portion. For example, first, the second clamping portion is opened by the second control portion, then the case is placed in the second clamping portion, and then the second clamping portion is controlled by the second control portion to clamp the case, so as to perform the subsequent case insertion operation.

[0023] In some embodiments, the case insertion device further includes a third clamping member. The third clamping member is located between the first clamping member and the second clamping member, and the third clamping member is fixedly disposed on the guide rail plate.

[0024] Thus, when the case insertion operation is performed, the case insertion operation between the battery cell and the case can be assisted by the third clamping member. For example, the case first moves into the third clamping member, and then the battery cell moves into the case, thereby realizing the case insertion operation. Since the third clamping member is fixedly disposed on the guide rail plate, the case insertion operation is relatively stable under the clamping of the third clamping member and is not likely to deviate.

[0025] In some embodiments, along the second direction, the distance between the first track groove and the second track groove in the third direction first gradually decreases and then gradually increases.

[0026] Thus, the battery cell clamped by the first clamping member and the case clamped by the second clamping member, under the action of the first track groove and the second track groove, correspondingly approach each other along the linear guide rail first and then move away from each other, so as to complete the case insertion operation between the battery cell and the case and the return operation after case insertion.

[0027] In some embodiments, along the second direction, the distance between the third track groove and the first track groove in the third direction gradually decreases.

[0028] Thus, the push rod assembly and the battery cell clamped by the first clamping member, under the action of the third track groove and the first track groove, correspondingly approach each other along the linear guide rail, so as to apply a thrust to the battery cell through the push rod assembly to assist the battery cell to enter the case.

[0029] In some embodiments, along the second direction, the distance between the fourth track groove and the second track groove in the third direction first gradually decreases and then gradually increases.

[0030] In this way, the shell clamped by the ejector pin assembly and the second clamping member approaches and then moves away from the linear guide rail gradually under the action of the fourth track groove and the second track groove, so as to guide the insertion of the battery cell into the shell and make the ejector pin withdraw after the insertion, completing the entire shell insertion process.

[0046] Please refer to Figure 1 and Figure 2 , the housing device 100 of the embodiment of the present application includes a bracket 10, a track plate 20, a guide rail plate 30, a first clamping member 40 and a second clamping member 50. The track plate 20 is fixedly installed on the bracket 10. On one surface of the track plate 20 in the first direction, a first track groove 21 and a second track groove 22 extending along the second direction are provided. The guide rail plate 30 is slidably installed on the bracket 10. The guide rail plate 30 is located on one side of the track plate 20 in the first direction. The guide rail plate 30 can slide in the second direction. A linear guide rail 31 along the third direction is provided on the guide rail plate 30. The first clamping member 40 includes a connected first clamping portion 41 and a first guiding portion 42 (such as Figure 5As shown in the figure, the first clamping part 41 is slidably arranged on the linear guide rail 31, and the first guiding part 42 extends into the first track groove 21. The second clamping member 50 includes a connected second clamping part 51 and a second guiding part 52 (as Figure 5 shown). The second clamping part 51 is slidably arranged on the linear guide rail 31, and the second guiding part 52 extends into the second track groove 22. 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 so as to approach or move away from each other.

[0047] In the housing inserting device 100 of the embodiment of the present application, 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 so as to approach or move away from each other, so that the first housing inserting object (such as an electric core) clamped by the first clamping member 40 is matched with the first housing inserting object (such as the housing 200) clamped by the second clamping member 50 to complete the housing inserting operation. The housing inserting device 100 can utilize the movement tracks of the first clamping member 40 and the second clamping member 50 to complete the housing inserting operation, realize automated operation, and has a relatively high housing inserting efficiency. In addition, the housing inserting device 100 has a simple structure, a small space volume, saves production costs, and also reduces the space occupied in the workshop.

[0048] Specifically, the bracket 10 can play a role in installing, supporting and protecting components such as the track plate 20, the guide rail plate 30, and the transmission component 60 in the following text. The bracket 10 can include a plurality of supporting parts, such as Figure 2 shown. The bracket 10 includes four supporting parts connected end to end in sequence, so that the structure of the bracket 10 is relatively stable. The four supporting parts are respectively a first supporting part 11, a second supporting part 12, a third supporting part 13 and a fourth supporting part 14. The first supporting part 11 and the third supporting part 13 are arranged in parallel and opposite to each other. The second supporting part 12 and the fourth supporting part 14 are arranged in parallel and opposite to each other. The extending direction of the first supporting part 11 and the third supporting part 13 is the second direction, and the extending direction of the second supporting part 12 and the fourth supporting part 14 is the third direction. The second direction is also the length direction of the housing inserting device 100 ( Figure 1 the left - right direction in the figure), and the third direction is also the height direction of the housing inserting device 100 ( Figure 1 the up - down direction in the figure).

[0049] The trackpad 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 trackpad 20 may have a square structure, such as a rectangular structure or a square structure. On one surface of the trackpad 20 in the first direction, a first track groove 21 and a second track groove 22 extending along the second direction are provided. The first direction is also the thickness direction of the housing device 100 ( Figure 1 the direction perpendicular to the paper surface in the figure). The trackpad 20 may be an integral trackpad 20, and the first track groove 21, the second track groove 22, and the third track groove 23 and the fourth track groove 24 described later are all formed in the trackpad 20; alternatively, the trackpad 20 may include four plates arranged along the third direction, and the first track groove 21, the second track groove 22, and the third track groove 23 and the fourth track groove 24 described later are respectively formed in the corresponding four plates. The extending directions of the first track groove 21 and the second track groove 22 are the second direction, and the tracks of the first track groove 21 and the second track groove 22 may be straight lines, curves, or a combination of straight lines and curves, etc., which are not limited herein.

[0050] The guide rail plate 30 is slidably mounted on the bracket 10. The guide rail plate 30 is located on one side of the trackpad 20 in the first direction, and the guide rail plate 30 can slide in the second direction. At this time, sliding guide rails 15 along the second direction can be provided on both the first support portion 11 and the third support portion 13, so that the upper and lower ends of the guide rail plate 30 can slide along the sliding guide rails 15 on the first support portion 11 and the third support portion 13 respectively, thereby realizing the sliding of the guide rail plate 30 in the second direction. A linear guide rail 31 along the third direction is also provided on the guide rail plate 30.

[0051] The first clamping member 40 includes a connected first clamping portion 41 and a first guiding portion 42. The first clamping portion 41 is slidably disposed on the linear guide rail 31, and the first guiding portion 42 extends into the first track groove 21. At least a part of the first clamping portion 41 is located on the side of the guide rail plate 30 facing away from the trackpad 20, and the first guiding portion 42 is located on the side of the guide rail plate 30 facing the trackpad 20. The first guiding portion 42 may be a cam follower. The second clamping member 50 includes a connected second clamping portion 51 and a second guiding portion 52. The second clamping portion 51 is slidably disposed on the linear guide rail 31, and the second guiding portion 52 extends into the first track groove 21. At least a part of the second clamping portion 51 is located on the side of the guide rail plate 30 facing away from the trackpad 20, and the second guiding portion 52 is located on the side of the guide rail plate 30 facing the trackpad 20. The second guiding portion 52 may be a cam follower.

[0052] 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, so as to approach or move away from each other. The specific process is 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 guiding portion 42 and the second guiding portion 52 slide along the first track groove 21 and the second track groove 22 respectively, and the first clamping portion 41 fixedly connected to the first guiding portion 42 and the second clamping portion 51 fixedly connected to the second guiding portion 52 move relative to each other along the third direction on the linear guide rail 31, so as to approach or move away from each other. The first object to be inserted into the shell (such as an electric core) clamped by the first clamping portion 41 and the first object to be inserted into the shell (such as the housing 200) clamped by the second clamping portion 51 also approach or move away from each other correspondingly, so as to cooperate to realize the shell insertion operation.

[0053] Please refer to Figures 1 to 3 , in some embodiments, the shell insertion device 100 further includes a transmission assembly 60. The transmission assembly 60 includes a driving fixed seat 61, a driven fixed seat 62, a transmission belt 63 and an actuating member 64. The driving fixed seat 61 and the driven fixed seat 62 are both fixedly installed on the bracket 10, and the actuating member 64 is arranged on the driving fixed seat 61 and is used to drive the transmission belt 63 to move along the second direction between the driving fixed seat 61 and the driven fixed seat 62. A fixed plate 32 is provided on the side of the guide rail plate 30 facing away from the linear guide rail 31, and the transmission belt 63 is fixedly connected to the fixed plate 32.

[0054] In this way, the actuating member 64 can be used to drive the transmission belt 63 to move along the second direction between the driving fixed seat 61 and the driven fixed seat 62, so as to drive the guide rail plate 30 to slide along the second direction through the fixed plate 32, thereby realizing the subsequent automatic shell insertion operation.

[0055] Specifically, the driving fixed seat 61 can be installed on one of the aforementioned second supporting portion 12 and the fourth supporting portion 14, and the driven fixed seat 62 is installed on the other of the aforementioned second supporting portion 12 and the fourth supporting portion 14. As Figure 2 in the example of, the driving fixed seat 61 is installed on the second supporting portion 12, and the driven fixed seat 62 is installed on the fourth supporting portion 14. The transmission belt 63 can be a synchronous belt (such as a belt), and the transmission belt 63 is transmission - arranged between the driving fixed seat 61 and the driven fixed seat 62. The actuating member 64 is arranged on the driving fixed seat 61. The actuating member 64 can be a handwheel, and the actuating member 64 can be pushed by an operator without an electric control element. By rotating the handwheel, the transmission belt 63 can be driven to move between the driving fixed seat 61 and the driven fixed seat 62.

[0056] The fixed plate 32 can be disposed on one side of the guide rail plate 30 facing the track plate 20 and fixedly connected to the transmission belt 63. For example, the fixed plate 32 clamps the transmission belt 63. Thus, when the transmission belt 63 moves between the driving fixed seat 61 and the driven fixed seat 62 along the second direction, the guide rail plate 30 is driven to move along the second direction through the fixed plate 32. On the side of the guide rail plate 30 facing the track plate 20, at a position corresponding to the transmission belt 63, an avoidance space 33 (as shown in Figure 3 is formed) to avoid the movement of the transmission belt 63 along the second direction and make the overall space volume of the case loading device 100 smaller. The fixed plate 32 can be disposed in the avoidance space 33.

[0057] 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 case loading device 100 is compact and the space 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.

[0058] Please refer to Figure 1 and Figure 2 , in some embodiments, a third track groove 23 extending along the second direction is further provided on one surface of the track plate 20 in the first direction. The case loading device 100 further 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 guiding portion 71 (as shown in Figure 5 ), and the third guiding portion 71 extends into the third track groove 23. When the guide rail 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 and approach or separate under the action of the third track groove 23 and the first track groove 21.

[0059] Thus, when the battery cell clamped by the first clamping member 40 cooperates with the housing 200 clamped by the second clamping member 50 for the case loading operation, a thrust can be applied along the second direction through the push rod assembly 70 to assist the battery cell to enter the housing 200 and realize the case loading operation between the battery cell and the housing 200.

[0060] 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 extending 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., and is not limited herein. On the guide rail plate 30, in the second direction in sequence are: the push rod assembly 70, the first clamping member 40, and the second clamping member 50. The battery cell is clamped by the first clamping member 40, and the housing 200 is clamped by the second clamping member 50. When the push rod assembly 70 moves in the second direction, a thrust can be applied to the battery cell on the side of the guide rail plate 30 provided with the linear guide rail 31, and a thrust can be applied to the first clamping portion 41 on the side of the guide rail plate 30 facing away from the linear guide rail 31.

[0061] Please refer to Figure 1 and Figure 2 , in some embodiments, the push rod assembly 70 includes a first pushing member 72, and the first pushing member 72 is located on the side of the guide rail plate 30 provided with the linear guide rail 31. The first clamping portion 41 includes a clamping jaw 411 (as shown in Figure 4 ), and the clamping jaw 411 is located on the side of the guide rail plate 30 provided with the linear guide rail 31. When the guide rail plate 30 drives the first clamping member 40 to slide along the second direction, the first pushing member 72 applies a thrust to the battery cell clamped by the clamping jaw 411.

[0062] In this way, during the housing insertion operation, the first pushing member 72 in the push rod assembly 70 can apply a thrust to the battery cell in the second direction to assist the battery cell to enter the housing 200, and the housing insertion operation between the battery cell and the housing 200 is realized.

[0063] Specifically, when the battery cell and the housing 200 cooperate for the housing insertion operation, the first pushing member 72 of the push rod assembly 70 applies a thrust behind the battery cell so that the battery cell moves into the housing 200. The first pushing member 72 is, for example, a push rod structure. The extending direction of the first pushing member 72 is consistent with the second direction to facilitate applying a thrust to the battery cell.

[0064] Please refer to Figure 2 , in some embodiments, the push rod assembly 70 further includes a pressure detection member 74 connected to the first pushing member 72. The pressure detection member 74 is used to detect the pressure value borne by the first pushing member 72 in the second direction.

[0065] In this way, the pressure value borne by the first pushing member 72 in the second direction can be detected by the pressure detection member 74. If the battery cell gets stuck during the housing insertion process or other problems cause the pressure of the first pushing member 72 to be too high, it can be detected in time by the pressure detection member 74, and an alarm can also be given in time according to needs to prompt the operator to check for abnormalities.

[0066] 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 pushing member 72 away from the first clamping member 40, so as to detect the pressure value borne by the first pushing member 72 in the second direction when the first pushing 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 positions of the first pushing member 72, and only by converting the pressure data detected by the pressure detection member 74 in real time, the pressure value borne by the first pushing member 72 in the second direction can be obtained.

[0067] As Figure 2 shown, the casing device 100 may further include a pressure display member 76 connected to the pressure detection member 74, such as a pressure display instrument, so as to alarm in time through the display instrument and prompt the operator to check for abnormalities when the pressure value detected by the pressure detection member 74 is too large (that is, the pressure borne by the first pushing member 72 is too large).

[0068] Please refer to Figure 2 and Figure 4 In some embodiments, the push rod assembly 70 further includes an elastic member 75 connected to the first pushing member 72. The first pushing member 72 includes an opposite mounting end 721 and an acting end 722. The acting end 722 is used to apply a thrust to the battery cell, and the elastic member 75 is located at the mounting end 721.

[0069] In this way, when the first pushing member 72 applies a thrust to the battery cell in the second direction, the battery cell reacts on the first pushing member 72, and the elastic action of the elastic member 75 can play a buffering and protecting role on the battery cell, avoiding damage to the battery cell caused by a sudden increase in the thrust.

[0070] Specifically, the elastic member 75 is, for example, a spring. The first pushing member 72 includes an opposite mounting end 721 and an acting end 722. The mounting end 721 is opposite to the acting end 722, and the acting end 722 faces the battery cell. In the initial state, the acting end 722 is spaced from the battery cell. The elastic member 75 is disposed at the mounting end 721. When the first pushing member 72 applies a thrust to the battery cell, the battery cell reacts on the first pushing member 72, and then acts on the elastic member 75. The reaction force of the elastic member 75 can play a buffering and protecting role on the battery cell.

[0071] Please refer to Figure 2 and Figure 5 In some embodiments, the push rod assembly 70 further includes a second pushing member 73. The second pushing member 73 is located on a side of the guide rail plate 30 facing away from the linear guide rail 31. The first clamping portion 41 further includes a back portion 412 connected to the jaw 411. The back portion 412 is located on a side of the guide rail plate 30 facing away from the linear guide rail 31. When the guide rail plate 30 drives the first clamping member 40 to slide along the second direction, the second pushing member 73 applies a thrust to the back portion 412 to loosen the jaw 411.

[0072] Thus, when performing the shelling operation, the second pusher 73 in the pusher assembly 70 can apply a thrust to the back 412 in the second direction to loosen the jaws 411, so that the battery cell moves to the housing 200 without the clamping force of the jaws 411, realizing the shelling operation between the battery cell and the housing 200.

[0073] Specifically, the aforementioned first pusher 72 is disposed on the side of the guide rail plate 30 opposite to the track plate 20 (as Figure 4 shown), and the second pusher 73 of the embodiment of the present application is disposed on the side of the guide rail plate 30 opposite to the track plate 20 (as Figure 5 shown). When the battery cell and the housing 200 are cooperatively performing the shelling operation, the second pusher 73 of the pusher assembly 70 applies a thrust to the first clamping portion 41 in the second direction, specifically acting on the back 412 of the first clamping portion 41, so as to loosen the first clamping portion 41, causing the jaws 411 of the first clamping portion 41 to release the battery cell, so that the battery cell loses the clamping force of the first clamping portion 41 and can be smoothly shelled.

[0074] Please refer to Figure 1 and Figure 2 , in some embodiments, a fourth track groove 24 extending in the second direction is further provided on one surface of the track plate 20 in the first direction. The shelling device 100 further includes a thimble assembly 80. The thimble assembly 80 is slidably disposed on the linear guide rail 31, and the thimble assembly 80 is located on the side of the second clamping member 50 away from the first clamping member 40. The thimble assembly 80 includes a fourth guiding portion 81 (as Figure 5 shown), and the fourth guiding portion 81 extends into the fourth track groove 24. When the guide rail plate 30 drives the thimble assembly 80 and the second clamping member 50 to slide along the second direction, the thimble assembly 80 and the second clamping member 50 slide along the linear guide rail 31 and approach or separate under the action of the fourth track groove 24 and the second track groove 22.

[0075] Thus, when the battery cell clamped by the first clamping member 40 and the housing 200 clamped by the second clamping member 50 are cooperatively performing the shelling operation, the thimble assembly 80 can guide the battery cell in the second direction, so that the pole column of the battery cell is aligned with the central axis of the housing 200, thereby ensuring the concentricity between the pole column of the battery cell and the housing 200 and improving the accuracy and production qualification rate of the shelling operation.

[0076] 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 extending 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 herein. On the guide rail plate 30, in the second direction in sequence are: the first clamping member 40, the second clamping member 50, and the thimble assembly 80. The battery cell is clamped by the first clamping member 40, the housing 200 is clamped by the second clamping member 50, and the thimble assembly 80 includes a guiding thimble 82. When the battery cell and the housing 200 are cooperatively engaged in the housing operation, the guiding thimble 82 extends into the housing 200 from the rear of the housing 200 and abuts against the pole of the battery cell, so as to play a buffering and guiding role during the housing process, making the pole of the battery cell coincide with the central axis of the housing 200. It should be noted that the position of the guiding thimble 82 can be set in advance to be consistent with the position of the central axis of the housing 200. In this way, during the housing process, only by the guiding thimble 82 abutting against the pole of the battery cell and guiding the housing, the pole of the battery cell can be made to coincide with the central axis of the housing 200. In the embodiment of the present application, the battery cell is, for example, a bare battery cell. The housing 200 is, for example, a steel shell, and the central axis of the housing 200 specifically refers to the central axis of the inner hole of the housing 200.

[0077] Please refer to Figure 2 and Figure 4 , in some embodiments, the first clamping member 40 further includes a first control portion 43 connected to the first clamping portion 41, and the first control portion 43 is used to control the clamping state of the first clamping portion 41; and / or the second clamping member 50 further includes a second control portion 53 connected to the second clamping portion 51, and the second control portion 53 is used to control the clamping state of the second clamping portion 51.

[0078] Thus, when the housing operation needs to be performed, the clamping state of the first clamping portion 41 can be controlled by the first control portion 43. For example, first, the first clamping portion 41 is opened by the first control portion 43, then the battery cell is placed in the first clamping portion 41, and then the first clamping portion 41 is controlled by the first control portion 43 to clamp the battery cell, so as to perform the subsequent housing operation. Similarly, when the housing operation needs to be performed, the clamping state of the second clamping portion 51 can be controlled by the second control portion 53. For example, first, the second clamping portion 51 is opened by the second control portion 53, then the housing 200 is placed in the second clamping portion 51, and then the second clamping portion 51 is controlled by the second control portion 53 to clamp the housing 200, so as to perform the subsequent housing operation.

[0079] 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 released state or a clamped state. When a pulling force is applied to the first control part 43, the first clamping part 41 switches from the clamped state to the released state; when the pulling force applied to the first control part 43 is released, the first clamping part 41 resumes the clamped state. In specific applications, when the shelling operation needs to be performed, the operator can apply a pulling force to the first control part 43 to make the first clamping part 41 switch from the clamped state to the released state, 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 make the first clamping part 41 resume the clamped state, and the first clamping part 41 clamps the battery cell for subsequent shelling operations.

[0080] 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 released state or a clamped state. When a pulling force is applied to the second control part 53, the second clamping part 51 switches from the clamped state to the released state; when the pulling force applied to the second control part 53 is released, the second clamping part 51 resumes the clamped state. In specific applications, when the shelling operation needs to be performed, the operator can apply a pulling force to the second control part 53 to make the second clamping part 51 switch from the clamped state to the released state, then place the housing 200 into the second clamping part 51, and then release the pulling force applied to the second control part 53 to make the second clamping part 51 resume the clamped state, and the second clamping part 51 clamps the housing 200 for subsequent shelling operations.

[0081] Please refer to Figure 1 and Figure 2 , in some embodiments, the shelling 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 the third clamping member 90 is fixedly arranged on the guide rail plate 30.

[0082] In this way, during the shelling operation, the shelling operation between the battery cell and the housing 200 can be supported by the third clamping member 90. For example, the housing 200 first moves into the third clamping member 90, and then the battery cell moves into the housing 200, thereby realizing the shelling operation. Since the third clamping member 90 is fixedly arranged on the guide rail plate 30, the shelling operation is relatively stable under the clamping of the third clamping member 90 and is not prone to deviation.

[0083] Specifically, during the shelling operation, the second clamping member 50 moves along the second direction (specifically, the direction from the second clamping member 50 towards the first clamping member 40, that is Figure 1Move in the upward direction from bottom to top in the figure, so that the housing 200 rises into the third clamping member 90, and the third clamping member 90 clamps the housing 200. Then, the first clamping member 40 moves along the second direction (specifically, the direction from the first clamping member 40 towards the second clamping member 50, that is Figure 1 the downward direction from top to bottom in the figure), so that the battery cell moves downward into the housing 200 to complete the operation of inserting the cell into the housing.

[0084] Please refer to Figure 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 gradually decreases first and then gradually increases. Among them, a process in which the distance remains unchanged may also be included between the gradual decrease and the gradual increase of the above distance.

[0085] In this way, the battery cell clamped by the first clamping member 40 and the housing 200 clamped by the second clamping member 50 gradually approach and then gradually move away along the linear guide 31 under the action of the first track groove 21 and the second track groove 22, so as to complete the operation of inserting the battery cell into the housing 200 and the return operation after the insertion.

[0086] Please refer to Figure 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. Among them, a process in which the distance remains unchanged may also be included after the above distance gradually decreases.

[0087] In this way, the push rod assembly 70 and the battery cell clamped by the first clamping member 40 gradually approach along the linear guide 31 under the action of the third track groove 23 and the first track groove 21, so as to apply a thrust to the battery cell through the push rod assembly 70 to assist the battery cell to enter the housing 200.

[0088] Please refer to Figure 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 gradually decreases first and then gradually increases. Among them, a process in which the distance remains unchanged may also be included between the gradual decrease and the gradual increase of the above distance.

[0089] In this way, the ejector pin assembly 80 and the housing 200 clamped by the second clamping member 50 gradually approach and then gradually move away along the linear guide 31 under the action of the fourth track groove 24 and the second track groove 22, so as to guide the insertion of the battery cell into the housing 200 and make the ejector pin withdraw after the insertion to complete the entire insertion process.

[0090] The following combines Figure 6 to illustrate the working process of the cell insertion device 100 according to the embodiments of the present application. As Figure 6As shown, the shell insertion operation may include four stages. In the first stage, 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, and correspondingly, the shell 200 moves from bottom to top into the third clamping member 90, and the guide ejector pin 82 moves from bottom to top into the shell 200. In the second stage, the distance between the third trajectory groove 23 and the first trajectory groove 21 gradually decreases, the distance between the first trajectory groove 21 and the second trajectory groove 22 gradually decreases, and the distance between the fourth trajectory groove 24 and the second trajectory 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, so that the battery cell completely enters the shell 200, and the guide ejector pin 82 starts to move downward and exits the shell 200. In the fourth stage, the distance between the second track groove 22 and the first track groove 21 gradually increases. Correspondingly, the shell 200 moves downward and retracts to its position, and the entire shell entry operation is completed.
