However, it should be understood that these practical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these practical details are not necessary. In addition, for the purpose of simplifying the drawings, some conventional structures and components will be depicted in a simple schematic manner in the drawings.

[0028] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0029] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0030] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0031] Please refer to Figure 1 and Figure 2 , Figure 1 It is a structural schematic diagram of the shell insertion device in an embodiment of the present invention; Figure 2 Another structural schematic diagram of the shell insertion device in the embodiment of the present invention. As shown in the figure, the shell insertion device of the present application includes a first clamping and transferring device 1, a second clamping and transferring device 2 and a shell insertion guide device 3. The first clamping and transferring device 1 and the second clamping and transferring device 2 are relatively arranged on both sides of the shell insertion guide device 3. In specific application, the first clamping and transferring device 1 and the second clamping and transferring device 2 respectively clamp the battery cell and the shell and relatively transfer them to the station of the shell insertion guide device 3 for shell insertion.

[0032] Refer to Figure 3 , Figure 31 is a schematic diagram of the structure of the first clamping and transferring device 1 in an embodiment of the present invention. As shown in the figure, the first clamping and transferring device 1 includes a moving mechanism 11, a carrying platform 12, a first transferring mechanism 13, a first clamping mechanism 14 and a supporting mechanism 15. The carrying platform 12 and the first transferring mechanism 13 are both arranged on the moving mechanism 11. The first clamping mechanism 14 is arranged on the carrying platform 12. The supporting mechanism 15 is arranged on the first transferring mechanism 13. In specific application, first, the battery cell is placed on the carrier 12, the first clamping mechanism 14 clamps the battery cell, and the supporting mechanism 15 supports the top cover of the battery cell, so that the bottom surface of the top cover is higher than the upper surface of the carrier 12; secondly, the moving mechanism 11 moves the carrier 12 and the first transfer mechanism 13 to the working position of the shell entry guide device 3; finally, the first transfer mechanism 13 pushes the battery cell on the carrier 12 to move toward the shell for shell entry. During the shell entry process, the supporting mechanism 15 supports the top cover to move toward the shell. After the battery cell is shelled to a certain extent, the supporting mechanism 15 can be retracted without continuing to support the top cover.

[0033] Preferably, a pad 121 is provided on the carrier 12, and the battery cell is placed on the pad 121, so that the contact area between the battery cell and the carrier 12 can be reduced, thereby reducing the friction when the first transfer mechanism 13 pushes the battery cell into the shell. In addition, in this embodiment, the pad 121 is made of ceramic material, and the friction between the ceramic pad 121 and the battery cell is not easy to generate dust, which can effectively avoid the influence of dust on battery quality.

[0034] The moving mechanism 11 includes a moving plate 111 and a moving driving member 112. The moving plate 111 is slidably arranged on the bottom plate 113 through a guide rail slider, and the bearing platform 12 and the first transfer mechanism 13 are both arranged on the moving plate 111. The output end of the moving driving member 112 is connected to the moving plate 111, and the moving driving member 112 is a cylinder. In specific application, the moving driving member 112 generates a driving force to drive the moving plate 111 to slide along the guide rail slider toward the direction of the shell entry guide device 3, and the moving plate 111 drives the bearing platform 12 and the first transfer mechanism 13 to move to the station corresponding to the shell entry guide device 3.

[0035] Preferably, the moving mechanism 11 further includes a moving buffer 114, which is disposed on one side of the bottom plate 113 and movably abuts against the moving plate 111. Specifically, the moving buffer 114 is a buffer, and when the moving driving member 112 drives the moving plate 111 to move in the shell entry direction, the moving buffer 114 plays a buffering and limiting role on the moving plate 111, thereby preventing the driving force of the moving driving member 112 from being too large, causing the moving plate 111 to collide with the shell entry guide device 3 and be damaged.

[0036] The first clamping mechanism 14 includes a first clamping assembly 141 and a second clamping assembly 142 which are arranged relatively to the carrier 12. In specific applications, the structures and operating principles of the first clamping assembly 141 and the second clamping assembly 142 are consistent. Below, the structures and operating principles of the first clamping assembly 141 and the second clamping assembly 142 are specifically described by taking the first clamping assembly 141 as an example.

[0037] The first clamping assembly 141 includes a first clamping driver 1411 and a first clamping plate 1412. The first clamping driver 1411 is arranged on the carrier 12, and the first clamping driver 1411 is a cylinder. The first clamping plate 1412 is connected to the output end of the first clamping driver 1411. Preferably, an in-place detection member 122 is provided on the carrier 12, and the in-place detection member 122 is a reflective photoelectric sensor. In specific applications, the in-place detection member 122 detects whether there is a battery cell on the carrier 12. If there is a battery cell, the in-place detection member 122 feeds back a signal to the control system of the shell entry device, and the control system of the shell entry device controls the first clamping driver 1411 to drive the first clamping plate 1412 to move in the direction of the battery cell. Similarly, the first clamping driver 1411 of the first clamping assembly 141 also drives the first clamping plate 1412 to move in the direction of the battery cell. The two first clamping plates 1412 clamp and fix the battery cell to prevent the battery cell from being displaced during the transfer process of the mobile mechanism 11.

[0038] The first transfer mechanism 13 includes a first transfer drive 131 and a transfer push rod 132. The first transfer drive 131 is disposed on the moving plate 111, and the first transfer drive 131 is a single-axis manipulator. The transfer push rod 132 is disposed on a slide plate 133 at the output end of the first transfer drive 131. After the moving mechanism 11 moves the carrier 12 and the first transfer mechanism 13 to the position, the first clamping mechanism 14 releases the battery cell, and the first transfer drive 131 drives the transfer push rod 132 to push the battery cell toward the shell entry guide device 3 to achieve shell entry.

[0039] Refer to Figure 4 , Figure 4 for Figure 3As shown in the figure, the supporting mechanism 15 includes a supporting driving member 151 and a supporting plate 152. The supporting driving member 151 is disposed on the slide plate 133, and the supporting driving member 151 is a cylinder. The supporting plate 152 is connected to the output end of the supporting driving member 151. When the transfer push rod 132 pushes the battery cell toward the shell entry guide device 3, the supporting drive member 151 also pushes the supporting plate 152 to move toward the shell entry guide device 3. The supporting plate 152 has a step 1521 that is compatible with the shape of the top cover of the battery cell. The step 1521 supports the top cover. When the step 1521 supports the top cover, the height of the bottom surface of the top cover is higher than the height of the upper surface of the pad 121, so that during the movement of the battery cell, the top cover does not contact the pad 121 or the supporting platform 12, and thus does not rub against each other. After the transfer push rod 132 pushes the battery cell to insert into the shell to a certain extent, the supporting drive member 151 drives the supporting plate 152 to restore to its initial position. At this time, the top cover does not contact the pad 121 or the supporting platform 12, and the transfer push rod 132 continues to push the battery cell until the shell entry is completed. After the shell entry is completed, the moving mechanism 11 and the first transfer mechanism 13 both return to their initial states, waiting for the next battery cell.

[0040] Refer to Figure 5 , Figure 5 Schematic diagram of the structure of the second clamping mechanism 22 in the embodiment of the present invention. As shown in the figure, the second clamping and transferring device 2 includes a second transferring mechanism 21 and a second clamping mechanism 22. The second transferring mechanism 21 is a single-axis manipulator. The second clamping mechanism 22 is arranged on the second transferring mechanism 21.

[0041] The second clamping mechanism 22 includes a clamping support plate 221, a second clamping drive member 222 and a second clamping plate 223. The clamping support plate 221 is arranged on the second transfer mechanism 21. The second clamping drive member 222 is arranged on the clamping support plate 221, and the second clamping drive member 222 is a bidirectional cylinder. The second clamping plate 223 is connected to the output end of the second clamping drive member 222 through a connecting plate. After the shell is placed on the clamping support plate 221, the opening of the shell faces the through hole 311, and the second clamping drive member 222 generates a driving force to drive the two second clamping plates 223 to move toward each other. The two second clamping plates 223 clamp the two opposite side walls of the shell to achieve clamping and fixing of the shell, and then the second transfer mechanism 21 transfers the shell on the clamping support plate 221 to the station of the shell entry guide device 3.

[0042] Preferably, the second clamping mechanism 22 further includes a limit block 224. The limit block 224 is disposed on the clamping support plate 221, and the limit block 224 limits the housing to prevent the housing from moving when the housing is inserted. In this embodiment, the limit block 224 is screwed to the clamping support plate 221 by a fastening screw, and the position of the limit block 224 can be adjusted by adjusting the position of the fastening screw, so that it can adapt to housings of different sizes.

[0043] Refer to Figure 6 , Figure 6 It is a schematic diagram of the structure of the shell entry guide device 3 in an embodiment of the present invention. As shown in the figure, the shell entry guide device 3 includes a mounting plate 31, a shell entry guide mechanism 32 and a shell entry suction port mechanism 33. The mounting plate 31 has a through hole 311. The shell entry guide mechanism 32 is arranged on the mounting plate 31. The shell entry suction port mechanism 33 is arranged on the shell entry guide mechanism 32. In specific application, the first clamping and transferring device 1 and the second clamping and transferring device 2 respectively transfer the battery cell and the shell to the work station of the shell entry guide device 3, and the shell entry suction port mechanism 33 sucks the shell to enlarge the opening of the shell, and the first clamping and transferring device 1 pushes the battery cell through the through hole 311 and enters the shell from the opening of the shell. When the first clamping and transferring device 1 pushes the battery cell, the shell entry guide mechanism 32 guides the battery cell so that the battery cell is pushed into the predetermined position of the shell to ensure the assembly accuracy.

[0044] Refer to Figure 7 , Figure 7 2 is a cross-sectional view of the shell entry guide mechanism 32 in the embodiment of the present invention. As shown in the figure, the shell entry guide mechanism 32 includes a first guide assembly 321 and a second guide assembly 322, and the first guide assembly 321 and the second guide assembly 322 are relatively arranged on the mounting plate 31. In specific applications, the structures and operating principles of the first guide assembly 321 and the second guide assembly 322 are consistent. Below, taking the first guide assembly 321 as an example, the structures and operating principles of the first guide assembly 321 and the second guide assembly 322 are specifically described.

[0045] The first guide assembly 321 includes a guide drive 3211 and a guide plate 3212. The guide drive 3211 is disposed on the mounting plate 31, and the guide drive 3211 is a cylinder. The guide plate 3212 is slidably disposed on the mounting plate 31 through a guide rail slider, and the guide plate 3212 is connected to the output end of the guide drive 3211. In specific applications, the mounting plate 31 has a through hole 311, and the guide plate 3212 has a guide groove 32121. The guide drive 3211 generates a driving force to drive the guide plate 3212 to slide to the corresponding through hole 311, and the first clamping and transferring device 1 pushes the battery cell from the opening of the shell into the shell, and the first clamping and transferring device 1 pushes the battery cell to pass through the through hole 311 and the guide groove 32121 in sequence to reach a predetermined position in the shell.

[0046] In specific application, the guide plate 3212 has a dust removal air path 32122 inside, and the dust removal air path 32122 is connected to the guide groove 32121. The dust generated during the shelling process can be cleaned by exhausting air through the dust removal air path 32122 to improve the quality of the battery.

[0047] Refer to Figure 8 and Fig. 9 , Figure 3 Schematic diagram of the structure of the guide plate 3212 in an embodiment of the present invention; Figure 41 is another structural schematic diagram of the guide plate 3212 in an embodiment of the present invention. As shown in the figure, the guide slot 32121 includes a guide opening 321211 and a limit opening 321212, the guide opening 321211 is located at one end of the guide slot 32121 close to the through hole 311, the limit opening 321212 is located at one end of the guide slot 32121 away from the through hole 311, and the guide opening 321211 is connected to the limit opening 321212.

[0048] In specific applications, the diameter of the guide opening 321211 gradually decreases from the side close to the through hole 311 to the side away from the through hole 311, so that the friction between the battery cell and the inner wall of the guide groove 32121 can be reduced. The diameter of the limit opening 321212 is larger than half of the diameter of the shell. In this way, when the second clamping and transferring device 2 transfers the shell to the station of the shell entry guide mechanism 32, the limit opening 321212 limits the shell to facilitate subsequent shell entry.

[0049] Refer to Fig.10 , Fig.10 3 is a cross-sectional view of the guide plate 3212 in the embodiment of the present invention. As shown in the figure, the cross section of the guide plate 3212 is "L" shaped, and the guide plate 3212 is set to be "L" shaped, which effectively increases the guide length of the guide groove 32121, thereby improving the accuracy of entering the shell.

[0050] Preferably, the shell entry guide mechanism 32 further includes a limit buffer 323, which is disposed on the guide plate 3212. When the two guide driving members 3211 drive the two guide plates 3212 to slide relative to each other, the two limit buffers 323 abut against each other to play a limit buffering role, thereby preventing the guide driving members 3211 from exerting too much force so that the two guide plates 321 collide with each other, thereby squeezing the battery cells and deforming the battery cells.

[0051] The shell suction port mechanism 33 includes a first suction port assembly 331 and a second suction port assembly 332. The first suction port assembly 331 and the second suction port assembly 332 are respectively arranged on the guide plates 3212 of the first guide assembly 321 and the second guide assembly 322, and the first suction port assembly 331 is opposite to the second suction port assembly 332. In specific applications, the structures and operating principles of the first suction port assembly 331 and the second suction port assembly 332 are consistent. Below, taking the first suction port assembly 331 as an example, the structures and operating principles of the first suction port assembly 331 and the second suction port assembly 332 are specifically described.

[0052] The first suction port assembly 331 includes a suction port driving member 3311 and a suction port member 3312. The suction port driving member 3311 is disposed on the guide plate 3212, and the suction port driving member 3311 is a cylinder. The suction port member 3312 is connected to the output end of the suction port driving member 3311, and the suction port member 3312 is a suction cup. After the second clamping and transferring device 2 moves the shell into place, the suction port driving member 3311 drives the suction port member 3312 to move toward the side wall of the shell, and the suction port member 3312 sucks the first outer side wall of the shell. Similarly, the suction port member 3312 of the second suction port assembly 332 sucks the second outer side wall of the shell opposite to the first outer side wall, and then, the suction port driving member 3311 drives the suction port member 3312 to move away from the shell, and the suction port member 3312 increases the distance between the first outer side wall and the second outer side wall opposite to each other of the shell, that is, the opening of the shell becomes larger, thereby facilitating the pushing in of the battery cell. At the same time, the friction between the battery cell and the inner side wall of the shell can be avoided during the pushing in of the battery cell, thereby reducing dust generation and improving battery quality.

[0053] Preferably, the first suction port assembly 331 further includes a suction port limit adjustment member 3313, which is arranged on the guide plate 3212. Specifically, the suction port limit adjustment member 3313 is a bolt, which is arranged on the guide plate 3212 through a bracket, and a nut is sleeved on the bolt, and the nut is located on both sides of the bracket, and the distance between the two nuts is the maximum stroke of the suction port driving member 3311 to drive the suction port member 3312 to move. When the two suction port driving members 3311 respectively drive the two suction port members 3312 to expand the shell opening, the suction port limit adjustment member 3313 limits the suction port member 3312 to prevent the suction port driving member 3311 from driving too much force and deforming the shell.

[0054] In specific applications, the first clamping and transferring device 1, the second clamping and transferring device 2 and the shell entry guide device 3 are all electrically connected to the control system of the shell entry device, and the control system of the shell entry device controls the first clamping and transferring device 1, the second clamping and transferring device 2 and the shell entry guide device 3 to achieve the effect of automatic control of the shell entry device. Of course, the control system of the shell entry device can be any one of an industrial computer, a PLC or a single-chip microcomputer, which will not be repeated here.

[0055] In summary, in one or more embodiments of the present invention, the shell entry equipment of the present invention guides the battery cell into the shell through the shell entry guide device, reduces the contact and friction between the battery cell and the shell, thereby reducing dust generation, and promptly cleans the dust generated by the contact between the battery cell and the shell during the shell entry process through the dust removal air path, avoiding the dust from affecting the battery quality.

[0056] The above is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
