Therefore, square lithium batteries have natural advantages in the industry, and square lithium batteries have also become one of the research focuses in the industry.

[0003] In the processing and production process of square lithium batteries, it is generally necessary to go through the steps of slurry mixing - coating - sheet making - winding - assembly - laser welding - liquid injection - formation - sealing - capacity division, etc. In the assembly process of square lithium batteries, it is necessary to align the battery cell and the aluminum shell first, and then install the battery cell into the aluminum shell. In the automatic shelling method currently used, the battery cell shell and the battery cell are located on different conveyor lines, and a guide piece is set between the conveyor line of the battery cell shell and the conveyor line of the battery cell. The guide piece is used to position the battery cell and the battery cell shell, and the battery cell is pushed into the battery cell shell along the guide structure of the guide piece by a push rod, thereby completing the automatic shelling of the battery cell.

[0004] In the prior art, the alignment of the battery cell and the shell is maintained by a guide member. After assembly, the finished product needs to be transferred from the guide member back to the assembly line. The assembled battery cell and shell need to be repositioned and calibrated again to carry out subsequent steps. This makes the structure of the equipment complex and cumbersome, the cost of the entire equipment is huge, and the processing and assembly efficiency is very low. Summary of the invention

[0006] The technical solution adopted by the present invention is: a battery cell shelling equipment, comprising: a first conveyor line, the first conveyor line is provided with a guide rail, the guide rail comprises a first horizontal section, a second horizontal section and a first transition section connected from the first horizontal section to the second horizontal section, the first horizontal section has a higher level than the second horizontal section; a tooling, the tooling comprises a roller installed on the guide rail, the tooling comprises an alignment portion for making the battery cell and the shell coaxial, the shell is arranged at the alignment portion, the battery cell is arranged below the first conveyor line and the battery cell is fed into the shell in the second horizontal section.

[0007] Furthermore, the battery cell shelling equipment also includes a second conveyor line for conveying the battery cells, and the second conveyor line is arranged below the first conveyor line.

[0008] Furthermore, the first transition section is in a stepped shape, and the first transition section includes a first downward sloping section, a third horizontal section, and a second downward sloping section connected in sequence.

DETAILED DESCRIPTION

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] The present application proposes a battery cell shelling device, see the attached Figures 1 to 7 As shown, the battery core shelling equipment mainly includes a first conveyor line 10 and a tool 100. The first conveyor line 10 can be a magnetic drive conveyor line or an ordinary belt transmission line. The first conveyor line 10 of this embodiment is a magnetic drive conveyor line. The first conveyor line 10 is used to convey the tool 100. A magnetic driver is arranged on the conveyor line. The magnetic driver slides on the conveyor line based on the principle of magnetic suspension. The tool 100 is installed and fixed on the magnetic driver. The magnetic driver drives the tool to be transported at a certain speed. The tool 100 is used to fix the shell 8, that is, the tool 100 can be operated on the first conveyor line 10. The shell 8 is conveyed, and the tooling 100 includes an alignment portion, on which the shell 8 is arranged. The tooling 100 is conveyed above the battery cell 7, and then the battery cell 7 is moved to the alignment portion, and the shell and the battery cell are kept roughly coaxially aligned. The alignment portion can be a chamber with a limiting function. The shell and the battery cell are simultaneously conveyed to the alignment portion so that the shell and the battery cell are within a specific range, and then a more accurate alignment operation is performed by the clamping alignment structure. The battery cell 7 and the shell 8 are aligned and pre-shelled by the alignment portion, so that the battery cell 7 and the shell 8 remain coaxially arranged, and then the operation of shelling the battery cell can be performed.

[0028] Furthermore, the first conveyor line 10 in the present application is a ring conveyor line, so that the magnetic driver can run on a predetermined route, which is convenient for cyclically transferring the shell 8 and continuously delivering the shell to the top of the battery cell 7, thereby improving the efficiency of the battery cell entering the shell.

[0029] Furthermore, if Figure 2As shown, at least two guide rails 101 are arranged on the first conveyor line, and roller groups are arranged on the tooling, each group of roller groups is correspondingly arranged in one guide rail 101, and the roller group includes at least one roller 1001, and the roller 1001 is installed on the guide rail 101. The guide rail 101 is used to define a specific running track of the tooling, wherein the guide rail 101 mainly includes a first horizontal section 102, a first transition section 103, a second horizontal section 104, and a second transition section 105, wherein the first horizontal section 102 and the second horizontal section 104 are both horizontally arranged, and the horizontal height of the first horizontal section 102 is higher than that of the second horizontal section 104, the first transition section 103 is connected from the first horizontal section 102 to the second horizontal section 104, and the second transition section 105 is connected from the second horizontal section 104 to the first horizontal section 102, and the first horizontal section 102 and the second horizontal section 104 are connected. A height difference is formed between the sections 104, so that the tooling falls downward when moving from the first horizontal section 102 to the second horizontal section 104, and the battery cell is arranged below the first conveyor line. When the tooling moves downward, the relative distance between the battery cell and the tooling becomes smaller, and the alignment part is aligned with the battery cell. The height of the tooling is lowered by setting a height difference on the guide rail 101, so that the alignment part of the tooling automatically moves down to the battery cell to send the battery cell into the alignment part in the second horizontal section 104. In this way, there is no need to transfer the battery cell, so that the efficiency of the battery cell entering the shell is greatly improved. When aligning, the tooling moves but the battery cell does not move, thereby eliminating the risk of damaging the fragile internal structure of the battery cell, and the overall structure is simple to implement. The sliding path of the roller 1001 on the guide rail 101 can remain stable for a long time, so it is not easy to cause the problem of poor alignment accuracy, and the cost of later maintenance and overhaul is extremely low.

[0030] Furthermore, the first transition section 103 is stepped, and the first transition section 103 includes a first downward sloping section 1031, a third horizontal section 1032 and a second downward sloping section 1033 connected in sequence. The height of the third horizontal section 1032 is between the first horizontal section 102 and the second horizontal section 104. In this way, the tooling will not be aligned in one step, but a staged descent method is adopted, and the tooling is first dropped to the height of the third horizontal section 1032. At this time, the distance between the tooling and the battery cell is closer, a part of the battery cell enters the alignment part, and the shell is fixed in the alignment part. In this way, even if there is a certain error in the coaxiality between the battery cell and the shell, it can be improved in this step, so that the error in the coaxiality of the battery cell and the shell can be reduced; after the tooling passes through the second downward sloping section 1033, it enters the second horizontal section 104. At this time, the height of the tooling is further reduced, and the interval between the battery cell and the shell is further reduced. The battery cell can be partially entered into the shell, so as to realize the pre-positioning of the battery cell and the shell, and finally the shell can be directly pushed onto the battery cell in one step. By setting the first transition section 103 to be stepped, the height of the tooling can be lowered in stages, the battery cell is first sent into the alignment portion, and then a part of the battery cell is sent into the shell, thereby avoiding the defect of damaging the battery cell structure caused by one-time alignment and installation, and improving the assembly quality of the battery cell into the shell.

[0031] The second transition section 105 is used to separate the tooling from the battery cell. The tooling rises through the second transition section, so that the tooling 100 and the assembled battery cell and shell are separated from each other. The assembled battery cell and shell proceed to the next step, and the tooling 100 continues to circulate on the first conveyor line 10 and picks up the next shell to execute the next battery cell shelling.

[0032] Furthermore, the battery cells in the present application are arranged on a second conveyor line for conveyance, and the second conveyor line is arranged below the first conveyor line, a first work section is arranged on the first conveyor line 10, and a second work section is arranged on the second conveyor line, the first work section is located directly above the second work section, and the conveying direction and conveying speed of the second work section parallel to the first work section are the same, and the battery cells are continuously conveyed on the second conveyor line. When the battery cells are conveyed to the second work section, the tooling 100 on the first conveyor line 10 moves synchronously with the battery cells, thereby completing the operation of putting the battery cells into shells in the area where the first conveyor line and the second conveyor line overlap, thereby greatly improving the production efficiency of the battery.

[0033] Preferably, the first conveyor line in the present application includes two upper and lower parallel guide rails 101, and the tooling includes two groups of rollers, each group of rollers is correspondingly arranged in a guide rail 101, so as to ensure that the tooling will not shake when it descends, thereby improving the accuracy of battery cell shelling.

[0034] Furthermore, if Figures 3 to 7As shown, in this embodiment, the alignment part in the present application includes a first clamping alignment mechanism 1, a second clamping alignment mechanism 2, a driving mechanism 3, a guiding mechanism 5 and a pressing mechanism 6, wherein the first clamping alignment mechanism 1 is used to clamp the battery cell 7, and the second clamping alignment mechanism 2 is used to clamp the shell 8. The clamping centers of the first clamping alignment mechanism 1 and the second clamping alignment mechanism 2 remain coaxial, and the driving mechanism 3 drives the first clamping alignment mechanism 1 and the second clamping alignment mechanism 2 to synchronously perform the clamping action so as to clamp the battery cell 7 and the shell 8 and keep them aligned, and the guiding mechanism 5 is used to guide the first clamping alignment mechanism 1 and the second clamping alignment mechanism 2 to slide toward each other, thereby guiding the battery cell 7 and the shell 8 to approach each other. After the battery cell 7 and the shell 8 are aligned and close to each other, the shell 8 is pressed onto the battery cell 7 by the pressing mechanism 6 to complete the entire action of the battery cell 7 entering the shell.

[0035] The guiding mechanism 5 of the tooling 100 mainly includes a fixed bracket 51 and a movable bracket 53. The fixed bracket 51 is used to support and fix the tooling 100 on the first conveyor line 10 for performing the step of putting the battery cell 7 into the shell. The movable bracket 53 is slidably connected to the above-mentioned fixed bracket 51, that is, the fixed bracket 51 is used to fix the tooling, and the movable bracket 53 slides on the fixed bracket 51, and can be used to perform actions such as clamping, aligning and assembling the battery cell 7 and the shell 8.

[0036] Furthermore, the movable bracket 53 includes a base plate 54, the second clamping alignment mechanism 2 is installed at the lower end of the base plate 54, and an alignment port is provided in the middle of the base plate 54. The fixed bracket 51 includes a fixed plate 52, and the fixed plate 52 is arranged parallel to the base plate 54, and the fixed plate 52 is arranged above the base plate 54. A suction cup assembly 61 is also arranged on the fixed bracket 51. The suction cup assembly 61 sucks the outer shell 8 by vacuuming with a vacuum machine. The suction cup assembly 61 is arranged opposite to the alignment port, so as to grab the outer shell 8 to the alignment port. In this embodiment, the fixed plate 52 is fixed on the magnetic driver, so as to be used to transport the tooling 100 to the top of the battery cell 7. The pressing mechanism 6 includes a telescopic driving device, which includes a push rod. The suction cup assembly 61 is arranged on the telescopic end of the push rod. The suction cup assembly 61 is pushed up and down by the telescopic driving device. The telescopic driving device is a power driving unit for pushing the outer shell. After the second clamping and alignment mechanism 2 and the first clamping and alignment mechanism 1 clamp the outer shell 8 and the battery cell 7 respectively, the telescopic driving device pushes the outer shell 8 to be mounted on the battery cell 7.

[0037] Furthermore, an upper extension plate 541 perpendicular to the bottom plate 54 is provided above the bottom plate 54 of the fixed bracket 51, and a lower extension plate 521 perpendicular to the fixed plate 52 is provided below the fixed plate 52 of the movable bracket 53. The upper extension plate 541 and the lower extension plate 521 are fitted together, and a set of slide rails are provided on the upper extension plate 541 and a slider is provided on the lower extension plate 521, so that the upper extension plate 541 and the lower extension plate 521 can slide relative to each other up and down.

[0038] The guiding mechanism 5 also includes a first guiding component 55 connected to the first clamping alignment mechanism 1 and a second guiding component 56 connected to the second clamping alignment mechanism 2. The first guiding component 55 and the second guiding component 56 are slidably connected to drive the battery cell 7 and the shell 8 to approach each other again; specifically, the battery cell 7 and the shell 8 are rectangular in shape. In order to better achieve the clamping alignment of the battery cell 7 and the shell 8, it is necessary to provide a clamping body around the battery cell 7 and the shell 8 to clamp the battery cell 7 and the shell 8. For ease of understanding, the present application takes the clamping body on one side of the battery cell 7 and the shell 8 as an example. The second clamping alignment mechanism 2 includes a second clamping body 21. The second clamping body 21 is arranged on one side of the shell 8 in the horizontal direction. The second clamping body 21 is a main body that performs the clamping action. The first clamping The alignment mechanism 1 includes a first clamping body 11 arranged on one side of the battery cell 7 in the horizontal direction, and the first clamping body 11 is used to clamp and center the battery cell 7, wherein the first clamping body 11 and the second clamping body 21 are located on the same side of the battery cell 7, and the first clamping body 11 and the second clamping body 21 are slidably connected through a first guide component 55 and a second guide component 56. The first guide component 55 can be a linear slide rail fixed on the first clamping body 11, and the second guide component 56 can be a slider fixed on the second clamping body 21. The second guide component 56 slides linearly on the first guide component 55. Since the slide rail is fixed on the first clamping body 11, when the second clamping body 21 slides, it will slide towards the first clamping body 11, so that the housing 8 and the battery cell 7 are close to each other.

[0039] Furthermore, the tooling 100 also includes a linkage mechanism 9, which includes a first linkage rod 91, the upper end of the first linkage rod 91 is fixedly connected to the lower end of the second clamping body 21, the lower end of the first linkage rod 91 faces the first clamping body 11, and the first clamping body 11 is provided with a first through hole 92 for the first linkage rod 91 to slide through, the first linkage rod 91 is clamped on the outside of the first through hole 92 relative to the lower end of the second clamping body 21, so that the sliding limit position of the first clamping body 11 and the second clamping body 21 can be limited, the driving mechanism 3 pushes the first linkage rod 91 to move horizontally toward the direction of the battery cell 7 and the housing 8, and by driving the driving device 31, the first clamping body 11 and the second clamping body 21 can be synchronously driven to perform the clamping action.

[0040] Furthermore, an elastic return member 93 is provided between the first clamping body 11 and the second clamping body 21. The elastic return member 93 is a spring. The spring is mounted on the first connecting rod 91, and the upper end of the spring abuts against the second clamping body 21, and the lower end of the spring abuts against the first clamping body 11. When the first clamping body 11 and the second clamping body 21 slide toward each other under force, after the battery cell 7 and the housing 8 are assembled, the first elastic return member 93 pops the first clamping body 11 and the second clamping body 21 apart.

[0041] Furthermore, the linkage mechanism 9 also includes a sleeve 94 and a second linkage rod 96, wherein the sleeve 94 is mounted and fixed on the fixed plate 52, the sleeve 94 is hollow, the second linkage rod 96 is arranged in the sleeve 94, and the second linkage rod 96 extends to the lower end of the sleeve 94, and the second linkage rod 96 slides up and down in the sleeve 94 to realize the extension and contraction of the second linkage rod 96, and a pair of oppositely arranged sliding grooves 95 are provided on the sleeve 94, and the sliding grooves 95 extend in a direction perpendicular to the horizontal direction, and the second linkage rod 96 is provided The sliding member 97 extends through the sliding groove 95 to the outside of the sleeve 94. A transmission plate 98 is also provided on the bottom plate 54. The transmission plate 98 abuts against the lower end of the sliding member 97, and a socket 962 is provided at the lower end of the second linkage rod 96. A plug plate 111 is also provided on the first clamping body 11 to penetrate into the socket 962, thereby limiting the first clamping body 11 from sliding downward. When the movable bracket 53 slides downward, the first clamping body 11 and the second clamping body 11 are synchronously driven to move. The first clamping body 21 slides downward, and the first clamping body 11 falls to both sides of the battery cell 7 until the sliding member 97 abuts against the bottom of the lower groove of the sliding groove 95 to prevent the second connecting rod 96 and the sleeve 94 from being separated. At this time, the first clamping body 11 slides to the limit position and no longer slides downward, but the second clamping body 21 continues to slide downward with the movable bracket 53, and under the clamping of the second clamping body 21, the housing 8 continues to move toward the battery cell 7 and compresses the elastic reset member 93. When the housing 8 is partially inserted into the battery cell 7, The first clamping alignment mechanism 1 and the second clamping alignment mechanism 2 simultaneously release the shell 8 and the battery cell 7, and the pressing mechanism 6 continues to push the shell 8 downward until the battery cell 7 is completely sent into the shell 8. When the battery cell 7 and the shell 8 are assembled, the movable bracket 53 slides upward, and the transmission plate 98 abuts against the sliding member 97 to make the second connecting rod 96 slide upward synchronously, and the second connecting rod 96 then drives the first clamping body 11 to slide upward, and at the same time the elastic reset member 93 elastically resets to bounce the first clamping body 11 and the second clamping body 21 apart.

[0042] Furthermore, a rolling bearing 961 is provided at the lower end of the socket 962, and the plug plate 111 is in contact with the rolling bearing 961, so that when the driving device 31 drives the first clamping body 11 to perform a clamping action, the plug plate 111 slides in the socket 962, and the rolling bearing 961 assists the plug plate 111 to slide, thereby reducing the sliding friction between the plug plate 111 and the socket 962.

[0043] The working principle of the present application is as follows: the tooling 100 is installed on the first conveyor line 10, and the first conveyor line 10 drives the tooling synchronously. First, the shell 8 is grabbed to the alignment port by the suction cup assembly 61, and then the first conveyor line 10 continues to drive the shell 8 to the top of the battery cell 7. The tooling moves downward under the action of the guide rail, the fixed bracket does not move, and the movable bracket 53 begins to slide downward under the force. The first clamping alignment mechanism 1 and the second clamping alignment mechanism 2 move downward accordingly with the movement of the movable bracket 53. When it moves to the third horizontal section 1032, the first clamping alignment mechanism 1 corresponds to the four sides of the battery cell 7, and the second clamping alignment mechanism 2 corresponds to the four sides of the shell 8. At the same time, the pressing mechanism 6 (telescopic drive device) pushes the shell 8 to move a short distance toward the direction of the battery cell 7, and the driving mechanism 3 drives the first clamping alignment mechanism 1 and the second clamping alignment mechanism 2 to synchronously perform clamping alignment, thereby adjusting the upper and lower positions of the battery cell 7 and the shell 8 and aligning the battery cell. 7 and the shell 8 are fixed; thereafter, the tooling continues to slide on the guide rail 101 until the second horizontal section 104, when the first clamping alignment mechanism 1 no longer moves downward, and the second clamping alignment mechanism 2 continues to move downward to insert a part of the shell 8 into the battery cell 7. When the second clamping alignment mechanism 2 slides to the limit position with the first clamping alignment mechanism 1, the second clamping alignment mechanism no longer moves downward, and finally the pressing mechanism 6 (telescopic drive device) pushes the shell 8 toward the battery cell 7 until the battery cell 7 is completely sent into the shell 8; when the tooling slides to the second transition section 105, the assembly of the battery cell 7 and the shell 8 is completed at this time, the movable bracket 53 slides upward, the transmission plate 98 abuts against the sliding member 97 to make the second connecting rod 96 slide upward synchronously, and the second connecting rod 96 then drives the first clamping body 11 to slide upward, and at the same time the elastic reset member 93 elastically resets, the first clamping body 11 and the second clamping body 21 are bounced apart, and the tooling is reset as a whole.
