Description

Technical Field

[0001] The present application relates to the technical field of battery assembly equipment, and in particular to a shell-into-pressurization tool and a press-assembly production line. Background Art

[0002] Shelling is a necessary and important process in the production of lithium batteries. The specific process is to press the battery cell into the shell, and then weld the battery cell and the shell to complete the assembly of some of the battery cells and the shell. Generally, when assembling lithium batteries, the battery cell is first fixed to the top cover, and then the top cover is placed on the carrier, and it flows along the carrier on the line to flow to different processing stations for processing. After the top cover and battery cell flow to different pressing stations, the outer shell is put on the battery cell, and the pressing device presses the outer shell to fit on the top cover.

[0003] In the related technology, it is necessary to set a power system on the carrier so that the carrier can flow on the line by itself, so as to drive the battery cells to flow to different stations. In addition, it is also necessary to set a clamping mechanism on the carrier to clamp the battery cells on the carrier and restrict the movement of the battery cells relative to the carrier. It is also necessary to release or partially release the clamping state of the battery cells by the clamping mechanism at the loading station, pressing station and unloading station. The battery cells can be driven to flow by the carrier, and the battery cells can also be adaptively clamped or released by the clamping mechanism on the carrier.

[0004] However, the carrier not only needs to be equipped with a power system that drives itself to circulate on the wire, but also needs to be equipped with a driving member to drive the clamping mechanism to operate, so as to clamp or release the battery cell. Therefore, the carrier needs to be equipped with a driving member and a matching transmission component to drive the carrier to circulate on the one hand and drive the clamping mechanism to operate on the other hand. Therefore, more structures need to be arranged on the carrier, resulting in a complex structure and a large weight of the carrier. In addition, since the carrier is provided with a driving member, it is also necessary to supply power to the driving member. The power supply line needs to be laid on the wire, which increases the complexity of the wire and the difficulty of design. Summary of the invention

[0059] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0060] The embodiment of the present application provides a shell-entry press-fitting tool and a press-fitting production line, in which the limiter in the shell-entry press-fitting tool is driven by elastic force to press against the top cover, and there is no need to set a drive member and a transmission mechanism on the carrier, which simplifies the structure of the carrier and makes the carrier lighter. In addition, an unlocking member is provided for an external linear drive member to apply force, thereby driving the limiter to overcome the elastic force and move away from the top cover. The linear drive member is provided on the line body to apply force to the unlocking member, so that the power source in the limit state of unlocking the top cover can be easily moved out of the carrier, which can simplify the carrier structure and reduce the difficulty of laying the line body. The present application solves the technical problems in the related art that the carrier structure is complex, the weight is large, and the laying and design difficulties of the line body are great.

[0061] Reference Figure 1 and Figure 2A shell-in-shell pressurization tool comprises a moving seat 1, a mounting seat 2 and a plurality of limiter assemblies 3 arranged on the moving seat 1. The moving seat 1 is circulated on the wire body, the mounting seat 2 is used to support the top cover a and the battery cell b, and the limiter assemblies 3 are used to clamp the top cover a on the mounting seat 2, so that the top cover a and the battery cell b can be circulated to different stations along with the moving seat 1, and the battery cell b can be processed in sequence.

[0062] Reference Figure 1 and Figure 2 Specifically, the moving seat 1 includes a base 11 and a stator part 12. The mounting seat 2 is fixed to the top surface of the base 11 by bolts, and the stator part 12 is integrated on the base 11. The stator part 12 is the stator part 12 in the linear motor. Correspondingly, the moving part of the linear motor is provided on the line body. The stator part 12 cooperates with the moving part, and the stator part 12 can move on the moving part. Therefore, the moving seat 1 is driven to rotate by magnetic drive.

[0063] It should be noted that in this embodiment, the stator part 12 is arranged on the base 11, and the stator part 12 cooperates with the mover part on the line body, which is similar to the reverse installation of the linear motor. The mover part requires external power, while the stator part 12 does not need external power. Therefore, the moving seat 1 does not need an external power line, which simplifies the structure of the moving seat 1, and the line body does not need to consider the routing problem of the external power line of the moving seat 1, which facilitates the setting of the line body and reduces the difficulty of designing and arranging the line body.

[0064] Reference Figure 1 and Figure 2 Furthermore, the mobile seat 1 further includes a plurality of guide wheels 13, which are rotatably connected to the bottom surface of the base 11. A guide groove may be correspondingly arranged on the line body, and the guide wheel 13 is suitable for sliding in the guide groove, thereby ensuring the flow direction of the mobile seat 1, and the mobile seat 1 moves more stably when flowing on the line body.

[0065] Reference Figure 1-Figure 3 The mounting seat 2 has a raised table surface, on which a plurality of support blocks are arranged, and the plurality of support blocks support the top cover a. The top surface of the support block is the support surface 2a of the mounting seat 2. By supporting the top cover a at multiple points, the stability of the top cover a on the support surface 2a is not easily affected by the flatness of the top cover a.

[0066] Reference Figure 1-Figure 3, wherein the limiting assembly 3 includes at least two groups, and the at least two groups of limiting assemblies 3 clamp the top cover a in two different directions respectively, so as to limit the top cover a on the mounting seat 2. The limiting assembly 3 includes two limiting members 31 and two unlocking members 32, and the limiting members 31 are elastically arranged on the mounting seat 2 or the moving seat 1. In this embodiment, the two limiting members 31 of the same group of limiting assemblies 3 are elastically arranged on the mounting seat 2 or the moving seat 1. The limiting members 31 of at least two groups of limiting assemblies 3 move in two different directions respectively, and a clamping space is formed between the four limiting members 31 of the two groups of limiting assemblies 3, and the top cover a is located in the clamping space. The two limiting members 31 of the same group of limiting assemblies 3 slide towards or away from each other, and under the action of elastic force, the two limiting members 31 slide towards each other and respectively press against the top cover a, thereby clamping and positioning the top cover a.

[0067] With this arrangement, since the limiter 31 is pressed against the top cover a by elastic force, there is no need to set a drive member and a transmission mechanism to drive the limiter 31 to move, thereby simplifying the structure of the carrier. When two limiters 31 in the same group move toward each other and clamp the top cover a, they will push the top cover a to between the two limiters 31 to position the top cover a relative to the mounting seat 2, so as to facilitate the subsequent pressing of the shell c onto the battery cell b. In addition, since the limiter 31 is pressed against the top cover a by the elastic force, the limiter 31 has a certain elastic movement range. Within the elastic movement range, the limiter 31 can press against the top cover a. Therefore, the limiter assembly 3 can clamp top covers a of different sizes, thereby improving the applicability of the carrier.

[0068] Reference Figure 3 and Figure 4 , the limiting member 31 includes a limiting seat 311, a first limiting portion 312 and a second limiting portion 313. Among them, the limiting seat 311 is elastically set on the moving seat 1 or the mounting seat 2. In this embodiment, part of the limiting seat 311 is elastically set on the moving seat 1, and part of the limiting seat 311 is elastically set on the mounting seat 2. The first limiting portion 312 is connected to the limiting seat 311, and a first limiting space is formed between the two first limiting portions 312 of the same group of limiting components, and the top cover a is located in the first limiting space and clamped by the two first limiting portions 312. The first limiting portion 312 includes a first limiting surface 312a, and the first limiting surface 312a is used to press against the top cover a. The first limiting surfaces 312a of the two limiting members 31 of the same group of limiting components 3 are arranged to face each other, and the two first limiting portions 312 are close to each other to clamp the top cover a.

[0069] Reference Figure 3-Figure 6, further, the first limit portion 312 is elastically arranged on the limit seat 311 along the press-fitting direction, and the press-fitting direction is the press-fitting direction of the shell. In this embodiment, the press-fitting direction is the vertical direction. Specifically, the limit member 31 also includes a limit elastic member 314, and the first limit portion 312 is slidably arranged on the limit seat 311 in the vertical direction through the guide rail group, and the two ends of the limit elastic member 314 are respectively fixed to the first limit portion 312 and the limit seat 311, so that the first limit portion 312 can be elastically arranged on the limit seat 311 through the limit elastic member 314. Among them, the limit elastic member 314 includes a spring or a buffer, and the number of the limit elastic members 314 is preferably two.

[0070] Reference Figure 3-Figure 6 The first position limiting portion 312 further includes a receiving surface 312b, which is used to support the outer shell c. After the outer shell c is sleeved on the battery cell b, the outer shell c is supported by the receiving surface 312b. When the receiving surface 312b receives the outer shell c, under the support of the limiting elastic member 314 on the first position limiting portion 312, the height of the receiving surface 312b is higher than the height of the top surface of the top cover a, so that the outer shell c stays at a position higher than the top cover a. Figure 10-12 When the shell c is pressed, the shell c simultaneously presses down the first limiting portion 312, and the first limiting portion 312 elastically descends to avoid a space for the shell c to descend, so that the shell c is completely mounted on the top cover a.

[0071] Due to the setting of the limiting elastic member 314, when the shell c falls onto the first limiting portion 312, under the buffering effect of the limiting elastic member 314, it is not easy to have a hard collision with the first limiting portion 312, thereby reducing the possibility of damage to the shell c.

[0072] Reference Figure 10-12 , the lowest point of the receiving surface 312b is lower than the supporting surface 2a or is flush with the supporting surface 2a. In this embodiment, the lowest point of the receiving surface 312b is flush with the supporting surface 2a. In this arrangement, when the shell c is press-fitted, when the receiving surface 312b is flush with the supporting surface 2a, the first limiter 312 has no space to continue to drop, and the shell c just fits the top cover a inside, completing the press-fitting process, reducing the possibility of over-pressing the shell c and damaging the shell c or the battery cell b.

[0073] Reference Figure 3 , Figure 10-12 Specifically, the position-limiting seat 311 includes a positioning surface 311a, and the first position-limiting portion 312 moves up and down just above the positioning surface 311a. When the first position-limiting portion 312 is lowered to abut against the positioning surface 311a, the first position-limiting portion 312 has no space to continue to fall, and the receiving surface 312b is flush with the supporting surface 2a. Therefore, the lowest height of the receiving surface 312b is controlled by the cooperation between the first position-limiting portion 312 and the positioning surface 311a.

[0074] Reference Figure 3 , Figure 10-12 Furthermore, the second limiting portion 313 is arranged above the first limiting portion 312, that is, the shell c first passes through the side of the second limiting portion 313 and then falls onto the receiving surface 312b. The second limiting portion 313 is connected to the first limiting portion 312 or the limiting seat 311. A second limiting space is formed between the two second limiting portions 313 of the same group of limiting components 3, and the shell is in the second limiting space when pressed. The second limiting portion 313 includes a second limiting surface 313a. In the elastic movement direction of the limiting seat 311, the distance between the two second limiting surfaces 313a of the same group of limiting components 3 is greater than the distance between the two first limiting surfaces 312a of the group of limiting components 3. The second limiting surface 313a is used to abut against the side of the shell c. When the first limiting surface 312a of the limiting member 31 abuts against the top cover a, the distance between the second limiting surface 313a of the limiting member 31 and the top cover a is equal to the wall thickness of the shell c, and the shell c can extend between the top cover a and the second limiting surface 313a.

[0075] With such arrangement, when the shell c is press-fitted, after the first limit surface 312a of the limit member 31 abuts against the top cover a, the position of the second limit surface 313a of the limit member 31 is determined, the shell c is sleeved onto the battery cell b, and under the positioning effect of the second limit surface 313a, the shell c falls onto the receiving surface 312b along the second limit surface 313a. Therefore, the shell c is aligned with the top cover a, and when the shell c is press-fitted, the shell c can be accurately sleeved onto the top cover a, and it is not easy for the shell c and the top cover a to collide due to misalignment, thereby improving the press-fitting quality of the shell c.

[0076] Reference Figure 10-13 It can be understood that when the multiple groups of limit assemblies 3 clamp the top cover a, the position of the top cover a is determined, and the position of the limiter 31 is also determined. The relative positions of the first limiter 312 and the second limiter 313 on the limiter 31 are determined, and after the first limiter surface 312a is pressed against the top cover a, the positions of the multiple second limiter surfaces 313a are also determined. After the shell c is sleeved on the battery cell b, the multiple side surfaces of the shell c are respectively in contact with the multiple second limiter surfaces 313a, so the position of the shell c is determined by the second limiter surfaces 313a, so that the shell c is aligned with the top cover a, so that the shell c is pressed more accurately.

[0077] Reference Figure 3 , Figure 10-12 In this embodiment, the second limiting portion 313 includes a limiting wheel, which is rotatably connected to the limiting seat 311 or the first limiting portion 312, and the circumferential side of the limiting wheel is the second limiting surface 313a. The limiting wheel contacts the shell c and is not easy to scratch the shell c.

[0078] Reference Figure 3 , Figure 10-12In this embodiment, the second limiting portion 313 is connected to the limiting seat 311. When the shell c is pressed, the shell c descends relative to the second limiting portion 313, and the second limiting portion 313 corrects the position of the shell c, so that the shell c is not easily deflected and pressed onto the top cover a.

[0079] In other embodiments, the second limiting portion 313 is connected to the first limiting portion 312. When the shell c is press-fitted, the second limiting portion 313 descends together with the shell c, and the second limiting portion 313 is not easy to move relative to the shell c, and is not easy to scratch the shell c.

[0080] Reference Figure 6 and Figure 8 , wherein the unlocking member 32 is connected to the limiting member 31, and the unlocking member 32 moves with the limiting member 31. The unlocking member 32 is used to slide under external force, so as to drive the unlocking member 32 and the limiting member 31 to overcome the elastic force and move, so that the limiting member 31 moves away from the top cover a and releases the limit on the top cover a. By setting the force point, it is convenient for the external linear driving member to drive the limiting member 31 to move, and it is convenient to move the power driving the limiting member 31 to the outside of the carrier, thereby simplifying the structure of the carrier and reducing the weight of the carrier.

[0081] When the carrier circulates on the wire body, it is necessary to release the limit on the top cover a in some specific stations, such as the loading station and the unloading station. It is only necessary to arrange a linear drive member at a specific station of the wire body. When the carrier circulates to the station, the linear drive member arranged on the wire body can drive the limit member 31 to move away from the top cover a. Compared with the drive member that drives the limit member 31 to move integrated on the carrier, there is no need to consider the layout of the power supply line supplied to the drive member when arranging the wire body, which simplifies the design of the wire body. The linear drive member arranged on the wire body may include a screw mechanism, a linear motor or a cylinder, etc.

[0082] Reference Figure 6 and Figure 8 Specifically, the unlocking member 32 includes an unlocking rod 321 and an unlocking wheel 322, and the unlocking rod 321 is connected to the limiting member 31. The unlocking wheel 322 is rotatably connected to the end of the unlocking rod 321 away from the limiting member 31, and the unlocking wheel 322 is used for external force, thereby driving the limiting member 31 to overcome the elastic force.

[0083] In this way, the unlocking rod 321 is set to lead the force position of the limiter 31 out, which is convenient for the external linear drive member to apply force. When the unlocking wheel 322 is set, when the external linear drive member applies force to the unlocking wheel 322, the unlocking wheel 322 is less worn than the unlocking rod 321.

[0084] Reference Figure 3 , Fig. 9 and Fig.13In this embodiment, according to the different clamping directions of the limit assembly 3, the multiple groups of limit assemblies 3 are divided into a first limit assembly and a second limit assembly. Among them, at least one group of first limit assemblies is included, and the clamping direction of the first limit assembly is set along the flow direction of the moving seat 1, that is, the two limit members 31 of the first limit assembly slide along the flow direction of the moving seat 1, and at least one group of second limit assemblies is included, and the clamping direction of the second limit assembly is set along a direction perpendicular to the flow direction of the moving seat 1, that is, the two limit members 31 of the second limit assembly slide along a direction perpendicular to the flow direction of the moving seat 1. It can be understood that the first limit assembly and the second limit assembly clamp the top cover a in two directions perpendicular to each other. In this embodiment, one group of first limit assemblies and two groups of second limit assemblies are included.

[0085] The shell-entry pressurizing device further comprises a plurality of first matching components 4, and the number of the first matching components 4 is consistent with the number of the first limit components. In this embodiment, the number of the first matching components 4 comprises one group.

[0086] Reference Figure 3-Figure 6 Specifically, the first matching assembly 4 includes a first matching elastic member 42 and two sliding seats 41. The two sliding seats 41 are both slidably arranged on the mounting seat 2 through a guide rail assembly. The sliding direction of the sliding seat 41 is arranged along the flow direction of the moving seat 1, and the two sliding seats 41 slide towards or away from each other. The two limiting members 31 of the first limiting assembly are respectively fixed to the two sliding seats 41. Therefore, the limiting members 31 are slidably arranged on the mounting seat 2 along with the sliding seats 41.

[0087] Reference Figure 3-Figure 6 , wherein the two ends of the first matching elastic member 42 are respectively connected to the two sliding seats 41 and respectively connected to the two limiting members 31, so as to elastically connect the limiting members 31 to the mounting seat 2. The first matching elastic member 42 comprises a tension spring or a spring. When the two limiting members 31 move away from each other, the first matching elastic member 42 is stretched, and the resilience of the first matching elastic member 42 drives the two limiting members 31 to move closer to each other, so as to center and clamp the top cover a, and facilitate the positioning of the top cover a. The number of the first matching elastic member 42 is preferably 2.

[0088] Reference Figure 3-Figure 6 The unlocking member 32 of the first limiting assembly is connected to the limiting seat 311 by connecting to the sliding seat 41. Through the connection of the sliding seat 41, the distance between the two unlocking members 32 of the first limiting assembly is closer.

[0089] Reference Figure 4-Figure 7Further, the first matching assembly 4 further includes a wedge block 43, which is slidably disposed on the mounting seat 2 along a direction perpendicular to the rotation direction of the moving seat 1, and the wedge block 43 is suitable for sliding between the two unlocking members 32 of the first limit assembly to push the two unlocking members 32 away from each other. The wedge block 43 is used to slide due to external force, and the external linear drive member pushes the wedge block 43 to push the two unlocking members 32 of the first limit assembly away from each other.

[0090] In this arrangement, the sliding direction of the two unlocking members 32 of the first limit assembly is arranged along the flow direction of the moving seat 1, so it is difficult for the external linear drive member to directly apply force to the unlocking member 32, and it is difficult for the external linear drive member to be arranged on the linear body. The movement direction of the wedge block 43 is perpendicular to the flow direction of the moving seat 1. The unlocking member 32 is driven to move by the wedge block 43. The external linear drive member can be arranged on both sides of the linear body without interfering with the passing position of the carrier, which facilitates the arrangement of the external linear drive member.

[0091] Reference Figure 7 Furthermore, a force-bearing roller is rotatably connected to the wedge block 43, and the force-bearing roller contacts the external linear drive member, thereby reducing the wear on the wedge block 43.

[0092] Reference Figure 3-Figure 6 , wherein the sliding seat 41 includes a sliding portion 411 and a mounting portion 412, wherein the sliding portion 411 is slidably disposed on the mounting seat 2 through a guide rail assembly and is located on the bottom surface of the mounting seat 2. wherein the unlocking member 32 of the first limiting assembly is fixed to the sliding portion 411, and the unlocking member 32 of the first limiting assembly is also located below the mounting seat 2, without occupying the space above the mounting seat 2. The mounting portion 412 is fixed to the sliding portion 411 by bolts, and the mounting portion 412 extends above the mounting seat 2, and the limiting member 31 of the first limiting assembly is fixed to the mounting portion 412.

[0093] Reference Figure 3-Figure 6 Further, the mounting portion 412 is slidably disposed on the sliding portion 411 and is consistent with the sliding direction of the sliding portion 411. The mounting portion 412 is fixed to the sliding portion 411 by bolts. After the position of the mounting portion 412 is adjusted relative to the sliding portion 411, the mounting portion 412 is fixed to the sliding portion 411 by bolts. In this embodiment, a waist-shaped groove is provided on the mounting portion 412, and the length direction of the waist-shaped groove is consistent with the sliding direction of the mounting portion 412. The waist-shaped groove is passed by the bolt to fix the mounting portion 412 on the mounting portion 412. In addition, in this embodiment, the first matching elastic member 42 is connected to the unlocking member 32 and connected to the sliding portion 411.

[0094] Reference Figure 3-Figure 6Furthermore, a limiting groove is provided on the sliding portion 411 , and the length direction of the limiting groove is consistent with the sliding direction of the mounting portion 412 . The mounting portion 412 slides in the limiting groove to limit the sliding direction of the mounting portion 412 .

[0095] With this arrangement, when the top cover a is clamped, the sliding distance that the sliding part 411 needs to slide relative to the mounting seat 2 can be changed by changing the position of the mounting part 412 relative to the sliding part 411. Since the first matching elastic member 42 is connected to the sliding part 411, the longer the sliding distance of the sliding part 411 toward the top cover a, the smaller the deformation of the first matching elastic member 42, the smaller the force applied to the sliding part 411 by the first matching elastic member 42, and the smaller the clamping force applied to the top cover a by the upper limit member 31 of the mounting part 412; the shorter the sliding distance of the sliding part 411 toward the top cover a, the greater the deformation of the first matching elastic member 42, the greater the force applied to the sliding part 411 by the first matching elastic member 42, and the greater the clamping force applied to the top cover a by the upper limit member 31 of the mounting part 412. By changing the position of the mounting portion 412 on the sliding portion 411 , the sliding distance of the sliding portion 411 toward the top cover a when the limiting member 31 clamps the battery cell b can be adjusted, thereby adjusting the clamping force on the top cover a to ensure that the top cover a is fixed.

[0096] Reference Figure 6 In addition, a scale is provided on the sliding portion 411, and the scale is provided along the sliding direction of the sliding portion 411. On the one hand, the position of the mounting portion 412 can be adjusted relative to the sliding portion 411 by referring to the scale line, so as to ensure that the relative positions of the mounting portions 412 and the sliding portions 411 of the two sliding seats 41 of the same first matching component 4 are consistent. On the other hand, after clamping the battery cell b, by referring to the scale line, it is also possible to observe whether the sliding distances of the two sliding portions 411 relative to the mounting seat 2 are consistent, and to check whether the battery cell b is clamped and fixed in the center.

[0097] Reference Figure 3 and Fig. 9 The shell-entry pressurizing tool further includes a plurality of second matching components 5, the number of the second matching components 5 is consistent with the number of the second limiting components. In this embodiment, the number of the second matching components 5 is 2.

[0098] Reference Figure 8 and Fig. 9 , wherein the second matching assembly 5 includes two supporting seats 51 and two second matching elastic members 52. The supporting seat 51 is fixed to the moving seat 1 by bolts. The two limiting members 31 of the second limiting assembly are respectively fixed to the two unlocking members 22 of the second limiting assembly by bolts or welding, and the two unlocking members 32 of the second limiting assembly are respectively slidably penetrated through the two supporting seats 51. Therefore, the two limiting members 31 of the second limiting assembly are slidably set on the moving seat 1 by being slidably set on the supporting seat 51.

[0099] Reference Figure 8 and Fig. 9 , the two ends of the second matching elastic member 52 are respectively connected to the unlocking member 32 and the support seat 51, and the unlocking member 32 is elastically connected to the support seat 51 through the first matching elastic member 42. Specifically, the second matching component 5 also includes a guide rod, one end of which is fixed to the limiter 31, and the guide rod is penetrated through the support seat 51. One end of the second matching elastic member 52 is fixed to the end of the guide rod away from the limiter 31, and the other end of the second matching elastic member 52 is fixed to the support seat 51. Therefore, when the limiter 31 moves away from the top cover a, the second matching elastic member 52 is stretched, and the limiter 31 is driven to press against the top cover a by the resilience of the second matching elastic member 52. Among them, the second matching elastic member 52 includes a spring or a buffer. When the second matching elastic member 52 includes a spring, the spring is sleeved on the guide rod to limit the bending of the spring. Among them, the number of the second matching elastic member 52 is preferably two.

[0100] Since the clamping direction of the second limiting assembly is perpendicular to the rotation direction of the moving seat 1, the limiting member 31 and the unlocking member 32 of the second limiting assembly both move perpendicular to the rotation direction of the moving seat 1, which makes it convenient to directly drive the unlocking member 32 and the limiting member 31 to move away from the top cover a through an external linear drive member, thereby arranging the external linear drive member on the linear body.

[0101] Reference Figure 8 and Fig. 9 Furthermore, a plurality of mounting grooves 2b are provided on the mounting seat 2, and the mounting grooves 2b are arranged throughout the mounting seat 2, and the clamping direction of the second limit assembly is consistent in the length direction of the mounting grooves 2b, and the support seat 51 is arranged in the mounting groove 2b. By changing the fixed position of the support seat 51 and the movable seat 1, the distance between the second limit assemblies in the same group can be adjusted. Since the limit member 31 is pressed against the top cover a by the elastic force of the second matching elastic member 52, by changing the fixed position of the support seat 51 and the movable seat 1, the distance between the support seat 51 and the top cover a is changed, and the top cover a of different specifications and sizes can be clamped and positioned.

[0102] Reference Figure 1 , Figure 3 , Figure 6 and Figure 8 The shell insertion and pressing tool further includes at least one set of auxiliary limiting components 6, the auxiliary limiting components 6 including two auxiliary limiting members 61, and the two auxiliary limiting members 61 are respectively arranged on the two limiting members 31 of the same set of limiting components 3. In this embodiment, the auxiliary limiting components 6 are provided in one set, and the two auxiliary limiting members 61 of the auxiliary limiting components 6 are respectively connected to the two limiting members 31 of the first limiting component.

[0103] Reference Figure 6 and Fig.14Specifically, the auxiliary limiting member 61 includes an auxiliary limiting seat 611 and an auxiliary limiting head 612, and the auxiliary limiting seat 611 is connected to the limiting member 31. In this embodiment, the auxiliary limiting seat 611 is fixed to the mounting portion 412 of the sliding seat 41 and is located above the second limiting portion 313. The auxiliary limiting head 612 is elastically arranged on the auxiliary limiting seat 611 along the elastic movement direction of the limiting member 31, and an auxiliary clamping space is formed between the two auxiliary limiting heads 612 of the same group of auxiliary limiting components 6, and the battery cell b or the shell c is suitable for being placed in the auxiliary clamping space, and the two auxiliary limiting heads 612 of the same group of auxiliary limiting components 6 are suitable for abutting against the battery cell b or the shell c.

[0104] Reference Figure 6 and Fig.14 , wherein the auxiliary limiting member 61 further includes an auxiliary limiting elastic member 613, and the two ends of the auxiliary limiting elastic member 613 are respectively connected to the auxiliary limiting head 612 and the auxiliary limiting seat 611, so that the auxiliary limiting head 612 is elastically set on the auxiliary limiting seat 611. Further, the auxiliary limiting member 61 may also include a limiting rod, which is fixed to the auxiliary limiting head 612, and the limiting rod is passed through the auxiliary limiting seat 611 and is slidably connected to the auxiliary limiting seat 611, thereby improving the stability of the auxiliary limiting head 612 moving relative to the auxiliary limiting seat 611. Wherein, the auxiliary limiting elastic member 613 includes a spring or a buffer, etc.

[0105] When the limiting member 31 of the first limiting assembly slides with the sliding seat 41 and presses against the top cover a, the auxiliary limiting member 61 also moves toward the battery cell b along with the sliding seat 41 and presses against the battery cell b. Therefore, when the top cover a is clamped, the auxiliary limiting assembly 6 clamps the battery cell b, thereby improving the placement stability of the top cover a and the battery cell b on the mounting seat 2.

[0106] Furthermore, after the shell c is sleeved on the battery cell b, since the auxiliary limit head 612 is elastically set on the auxiliary limit seat 611, the auxiliary limit head 612 can move away from the battery cell b relative to the auxiliary limit seat 611, and the shell c can be inserted between the auxiliary limit head 612 and the battery cell b, and then the auxiliary limit head 612 presses against the shell c to clamp the shell c.

[0107] Reference Figure 6 and Fig.14 The auxiliary limiting head 612 includes an auxiliary limiting frame 6121 and an auxiliary limiting wheel 6122, and the auxiliary limiting frame 6121 is connected to the auxiliary limiting seat 611 through an auxiliary limiting elastic member 613. The auxiliary limiting wheel 6122 is rotatably connected to the auxiliary limiting frame 6121, and the auxiliary limiting wheel 6122 is suitable for abutting against the battery core b or the housing c.

[0108] In this arrangement, the auxiliary limiting wheel 6122 contacts the battery cell b or the shell c. When the auxiliary limiting wheel 6122 moves relative to the battery cell b or the shell c, the auxiliary limiting wheel 6122 rolls on the surface of the battery cell b or the shell c without easily scratching the battery cell b or the shell c.

[0109] The embodiment of the present application provides a shell-in-shell pressing vehicle, which carries a top cover a and a battery cell b and drives the top cover a and the battery cell b to flow between different processing stations. The top cover a is supported by a mounting seat 2, and the top cover a is in a clamping space. A plurality of limit assemblies 3 are used to clamp the top cover a in two directions respectively, so as to position the top cover a on the mounting seat 2, so as to determine the position of the top cover a relative to the mounting seat 2, so as to facilitate the accurate pressing of the shell c onto the battery cell b. In the process of positioning and clamping the top cover a, the limit member 31 is driven by elastic force to press against the top cover a. When it is necessary to release the limit on the top cover a, the unlocking member 32 is used to slide under external force, so as to drive the limit member 31 to overcome the elastic force and move away from the top cover a. Since it is only necessary to release the limit on the top cover a at a specific station, it is only necessary to set a linear drive member at a specific station of the line body. Compared with laying a power supply line on the line body, setting a linear drive member on the line body is less expensive and less difficult to lay the line body. Since the limiter 31 is driven by elastic force to press against the top cover a on the carrier, the top cover a can be limited, and the carrier does not need to be provided with a driving member and a transmission mechanism, which simplifies the structure of the carrier and makes the carrier lighter. In addition, the limiter 31 is driven by elastic force to press against the top cover a, and the limiter 31 has a range of motion. Therefore, the limiter 31 can be used to adaptively clamp and limit top covers a of different sizes, making the carrier more applicable.
