[0002] With the rapid development of the new energy industry, batteries, as the main energy components in the new energy industry, are key components of new energy products and directly affect the main performance of new energy products. In battery production, under the premise that no major breakthroughs have been made in the field of raw materials, appropriately streamlining battery components, simplifying production processes, and saving manufacturing costs have become the exploration direction of major battery factories.

[0003] In the current production process of square shell batteries in the new energy industry, the battery cells will be placed in the shell assembly after the shell parts are assembled, and then the pole ears will be welded and the shell will be sealed.

[0004] Energy density is an important indicator of batteries. Under the condition of a certain battery capacity, major battery manufacturers will improve the energy density of batteries by streamlining battery components and reducing the internal space of the shell as much as possible. Due to the small internal space of the shell and the fact that the battery cell is the last part to be put into the shell, it is difficult for the battery cell fixture to be assembled into the shell as the battery cell is inserted into the shell, especially for batteries with multiple cells placed inside the shell. The difficulty of inserting the battery into the shell is great, and the process time is doubled. Summary of the invention

[0005] In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a battery core shell insertion device to solve at least one of the above-mentioned technical problems.

[0006] According to one aspect of the utility model specification, a battery core shell insertion device is provided, comprising:

[0007] A placement platform, wherein at least one battery cell placement position is provided on the placement platform;

[0008] A material taking component, the material taking component is used for transferring the shell;

[0020] As a further technical solution, the clamping part and the placement platform are both arranged in parallel with long strips, and hollows are provided between the strips. When the clamping part moves to face the placement platform, the long strip structure of the clamping part corresponds to the hollow part on the platform, so that the clamping part can be inserted into the bottom of the battery cell, support the bottom to clamp the battery cell and the shell together, and turn it upside down.

After the shell and the battery cell are docked, the docked battery cell and the shell are clamped and fixed by the clamping assembly, and the clamping assembly is connected to the turntable. At this time, the turntable is driven to rotate by the driving member, and the clamping assembly, the docked battery cell and the shell can be flipped as a whole, so that the shell is at the bottom and the battery cell is at the top, thereby completing the battery cell into the shell.

[0026] As a further technical solution, the material taking assembly and the flipping assembly are respectively arranged on a movable mechanism, and / or the placement platform is arranged on the movable mechanism. The material taking assembly is driven to move by the movable mechanism to realize the shell transfer and / or docking with the battery cell.

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions of various embodiments of the utility model in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] The utility model provides a battery cell shelling device, which avoids the interference of the shell 3 with the battery cell clamp when the battery cell is clamped into the shell by the clamp in the existing method of first docking and then flipping into the shell, and solves the problem of slow shelling of multiple batteries in traditional square shell batteries. At the same time, the utility model can shell multiple batteries 4 at a time, reducing the time of the battery cell shelling process. In addition, the utility model does not need to consider redesigning the clamp to clamp the battery cell 4 and put it into the shell for flat batteries 4 or special-shaped batteries 4. It only needs to dock the shell with the battery cell, and the docked battery cell and the shell can be flipped as a whole to complete the shelling of the flat battery cell 4 or the special-shaped battery cell 4.

[0043] It should be noted that if a special-shaped battery cell 4 needs to be shelled, the special-shaped battery cell 4 is first placed on a support frame 15, and then the shell 3 is docked with the special-shaped battery cell 4. The special-shaped battery cell 4 is matched with the corresponding position in the shell 3 and the docking is completed. Then, the docked battery cell 4 and the shell 3 are clamped and fixed by a clamping assembly, and the whole is flipped over to complete the shelling of the special-shaped battery cell 4, without the need to clamp the special-shaped battery cell 4 separately and put it into the shell 3.

[0044] The placement of the special-shaped battery cell 4 on the support frame 15 can be achieved by using a clamp, and a limit block can also be provided on the support frame 15 to position the placed special-shaped battery cell 4.

[0045] like Figure 1 As shown, the battery cell shelling device includes a placement platform 100, and at least one battery cell placement position is arranged on the placement platform 100; a material picking component 200, and the material picking component 200 is used to transport the shell 3; a clamping component 300, and the clamping component 300 is used to clamp the docked shell 3 and the battery cell 4; a flipping component 400, and the flipping component 400 is connected to the clamping component 300, and is used to drive the shell 3 and the battery cell 4 clamped by the clamping component 300 to flip to a preset angle.

[0046] The placement platform 100 is configured to be movable so that the battery cell can be docked with the shell from bottom to top, or the material removal component 200 is configured to be movable so that the shell can be docked with the battery cell from top to bottom, that is, the shell 3 and the battery cell 4 are docked in the vertical direction by moving the battery cell 4 or fixing the shell 3.

[0047] In one embodiment, Figure 2 As shown, the material taking component 200 is arranged on the robot arm 1. After the material taking component 200 takes the shell, the robot arm 1 drives the material taking component 200 to move, so that the taken shell 3 is docked with the battery cell 4 in the vertical direction.

[0048] The material taking assembly 200 includes a connecting plate 13, on which a plurality of suction cups 14 are disposed. The suction cups 14 are used to absorb the outer surface of the shell 3, and the robot arm 1 is used to move the shell 3 to the top of the battery cell 4 and dock with the battery cell 4.

[0049] Optionally, the suction cups 14 are provided in two groups, each group has 2 to 6 suction cups, and the two groups of suction cups are symmetrically arranged on the connecting plate 13 .

[0050] Furthermore, the size of the connecting plate 13 is slightly smaller than that of the shell 3, so that the suction cup 14 provided on the connecting plate 13 can stably adsorb the outer surface of the shell 3 without occupying additional operating space.

[0051] In another embodiment, the suction cup 14 is used to absorb and fix the outer surface of the housing 3, and the placement platform 100 is moved and lifted upward, so that the battery cell 4 on the placement platform 100 is docked with the housing 3. The movement of the placement platform 100 can be achieved by a robotic arm.

[0052] In one embodiment, a second robot arm 2 is arranged at a position opposite to the first robot arm 1 at the shell insertion station. A flip assembly 400 and a clamping assembly 300 are arranged on the second robot arm 2. The second robot arm 2 is configured to clamp or release the docked battery cell 4 and the shell 3 by the clamping assembly 300, and to flip the docked battery cell 4 and the shell 3 as a whole by a preset angle by the flip assembly 400 to complete the battery cell shell insertion.

[0053] The flipping assembly 400 and the clamping assembly 300 are arranged on the robot arm 2, and the movement of the robot arm 2 drives the overall movement. Before flipping, they can be moved away from the battery cell placement position without affecting the docking of the shell 3 with the battery cell 4 performed by the robot arm 1. After the docking is completed, they can be moved to the battery cell placement position, and the docked battery cell 4 and the shell 3 are flipped as a whole and sent to the next process.

[0054] like Figure 3As shown, the flip assembly 400 includes a turntable 6 and a driving member connected to the turntable 6, and one end face of the turntable 6 is connected to the clamping assembly. After the shell 3 and the battery cell 4 are docked, the docked battery cell 4 and the shell 3 are clamped and fixed by the clamping assembly, and the clamping assembly is connected to the flip assembly 400. At this time, the turntable 6 is driven by the driving member to rotate, and the clamping assembly 300, the shell 3 and the battery cell 4 can be turned over as a whole, so that the shell 3 is at the bottom and the battery cell 4 is at the top, thereby completing the battery cell into the shell.

[0055] Furthermore, a mounting plate 5 is provided at the end of the second robot arm 2 , and a flip assembly 400 is fixed on the mounting surface of the mounting plate 5 .

[0056] In practical applications, the driving member can be realized by an electric driving member or a cylinder driving member.

[0057] In one embodiment, the clamping assembly includes a first clamping portion and a second clamping portion that are symmetrically arranged, and the first clamping portion and the second clamping portion are driven by a driving device to complete the opening and clamping actions of the clamping portion. The clamping assembly is fixedly connected to the flip assembly 400, and after the first clamping portion and the second clamping portion clamp the docked battery cell 4 and the shell 3, the shell 3 and the battery cell 4 are flipped under the drive of the flip assembly 400.

[0058] In another embodiment, if Figure 4 As shown, the clamping assembly 300 includes two groups of parallel slides 8, each group of the slides 8 is connected to two sliders, each slider is connected to a clamping portion, and the two sliders are arranged opposite to each other and move toward or in the opposite direction along the slides 8 to achieve the clamping or loosening of the two clamping portions. It should be noted that the movement toward each other here refers to the two sliders moving from both ends of the slide 8 to the center at the same time, and the opposite movement refers to the two sliders moving from the center of the slide 8 to both ends at the same time.

[0059] Optionally, the upper ends and lower ends of the two groups of slide grooves 8 are kept flush to ensure that the lowest point and the highest point of the slider moving in the two groups of slide grooves 8 are the same.

[0060] Furthermore, each group of the slide slots 8 includes an upper slider 9 and a lower slider 10, and the two upper sliders 9 have the same highest movable point in the slide slots 8, and the two lower sliders 10 have the same lowest movable point in the slide slots 8. The upper sliders 9 and the lower sliders 10 are both fixedly connected with clamping parts, namely, a first clamping part 11 and a second clamping part 12. The upper sliders 9 and the lower sliders 10 move toward or in the opposite direction along the slide slots 8 to achieve the clamping or loosening of the first clamping part 11 and the second clamping part 12.

[0061] Furthermore, the clamping assembly further comprises a sliding cylinder or an electric cylinder 7. The sliding cylinder or the electric cylinder 7 is used to drive the slide block to move.

[0062] Optionally, four sliding cylinders or electric cylinders 7 may be configured to correspond to the two upper sliders 9 and the two lower sliders 10. During operation, two sliding cylinders or electric cylinders 7 drive the two upper sliders 9 to move up or down, while the other two sliding cylinders or electric cylinders 7 drive the two lower sliders 10 to move down or up.

[0063] In another embodiment, the clamping assembly 300 includes a slide groove 8 which is centrally disposed on the turntable 6 , and two sliders are connected to the slide groove 8 . The two sliders are disposed opposite to each other and move toward or in opposite directions along the slide groove 8 .

[0064] Furthermore, the slide 8 includes an upper slide block 9 and a lower slide block 10 .

[0065] Furthermore, the clamping assembly 300 further includes a sliding cylinder or electric cylinder 7. The sliding cylinder or electric cylinder 7 is used to drive the slider to move. For example, two sliding cylinders or electric cylinders 7 can be configured to correspond to the upper slider 9 and the lower slider 10 respectively. During operation, one sliding cylinder or electric cylinder 7 drives the upper slider 9 to move up or down, while the other sliding cylinder or electric cylinder 7 drives the lower slider 10 to move down or up.

[0066] Optionally, the first clamping portion 11 and the second clamping portion 12 each include a plurality of evenly arranged racks.

[0067] Furthermore, the racks of the first clamping portion 11 and the second clamping portion 12 are the same in number and are positioned opposite to each other.

[0068] Optionally, the clamping part and the battery cell placement platform 100 are both arranged in parallel with long strip structures, and hollows are provided between the strips. When the clamping part moves to face the placement platform 100, the long strip structure of the second clamping part 12 corresponds to the hollow part on the placement platform 100, so that the second clamping part 12 can be inserted into the bottom of the battery cell 4, support the bottom to clamp the battery cell 4 and the housing 3 together, and turn it upside down.

[0069] In one embodiment, the placement platform 100 is placed between the robot arm 1 and the robot arm 2 and is fixed, and the shell 3 and the battery cell 4 are docked by moving the shell 3.

[0070] like Figure 5 As shown, the placement platform 100 includes a plurality of support frames 15 arranged at intervals, and the interval between two adjacent support frames 15 is greater than the width of the rack, so that the rack of the second clamping part 12 can pass through the interval and abut against the surface of the battery cell 4, and the rack of the first clamping part 11 abuts against the surface of the shell 3, thereby achieving overall clamping of the shell 3 and the battery cell 4.

[0071] The support frame 15 can be placed on the shell insertion station. When in use, one or more cells 4 to be placed are placed on the support frame 15, the shell 3 is clamped by the mechanical arm 1, the shell 3 is docked with the cell 4, and then the rack of the second clamping part 12 is passed through the gap between the support frames 15 and abutted against the surface of the cell 4 by the mechanical arm 2, and the rack of the first clamping part 11 is abutted against the surface of the shell 3, and the slider drives the first clamping part 11 and the second clamping part 12 to move relative to each other to clamp and fix the cell 4 and the shell 3, and then the flip assembly drives the clamped cell 4 and the shell 3 to flip together by a preset angle to complete the cell shell insertion.

[0072] Optionally, the preset angle may be 180°.

[0073] Optionally, each of the support frames 15 adopts a gantry structure, which forms a space between the lower surface of the battery cell and the surface of the production line station, so that the clamping part can pass through.

[0074] It should be noted that the utility model avoids the disadvantage of using a suction cup or other clamps to place the battery cell 4 into the shell 3 by docking the shell 3 with the battery cell 4 in the vertical direction. Therefore, the purpose of clamp-free insertion can be achieved by moving the robot arm 1 to dock the shell 3 with the battery cell 4 from top to bottom, or by moving the placement platform to dock the battery cell 4 with the shell 3 from bottom to top.

[0075] In another embodiment, the placement platform is connected to a robot arm three (not shown in the figure), and the placement platform is lifted or lowered by the robot arm three, so that the shell 3 and the battery cell 4 are docked by moving the battery cell 4.

[0076] As an implementation method, multiple battery cells 4 are stacked up and down and placed on a placement platform, and the multiple battery cells 4 are positioned by a limiting structure provided on the placement platform. After the battery cells 4 are placed, the housing 3 is docked with the battery cells 4 from top to bottom by moving the robot arm 1, or the battery cells 4 are docked with the housing 3 from bottom to top by moving the placement platform, and then the docked housing 3 and battery cells 4 are turned over as a whole at a preset angle to complete the simultaneous entry of multiple battery cells 4 into the housing. Compared with the existing method of placing battery cells 4 into the housing 3 one by one using a robot arm, the method of simultaneously entering multiple battery cells 4 into the housing in this implementation method can greatly reduce the time of the battery cell entry process and improve the efficiency of entry.

[0077] Specifically, the vertical stacking of multiple battery cells 4 can be achieved by using existing fixtures, and the positioning on the placement platform can be achieved by using limit blocks and the like.

[0078] As an implementation method, multiple battery cells 4 are laid flat on the placement platform, and the battery cells 4 are positioned by the limiting structure provided on the placement platform. Different battery cell placement methods are related to the accommodation position of the battery cells 4 in the housing 3. The specific battery cell 4 placement method can be selected according to actual needs, and the utility model does not limit the specific placement method.

[0079] The use steps of the utility model include:

[0080] Step 1: Place the required number of cells 4 on the support frame 15 of the placement platform, and position the cells by the limit blocks on the placement platform. The placement of the cells 4 can be achieved by using an existing fixture.

[0081] Step 2: Robot arm 1 uses suction cup 14 to absorb shell 3, and moves shell 3 to dock with battery cell 4 from top to bottom. Alternatively, robot arm 1 uses suction cup 14 to absorb shell 3, and robot arm 3 moves the placement platform to dock battery cell 4 with shell 3 from bottom to top.

[0082] In step 3, the robot arm 1 moves away, and the robot arm 2 moves to the position of the battery cell 4. The sliding cylinder or electric cylinder 7 drives the slider to move, driving the first clamping part 11 and the second clamping part 12 to move, so as to clamp the battery cell 4 together with the shell 3; then the turntable 6 is driven to rotate 180°, driving the clamping part connected to the turntable 6 to rotate, so as to realize the overall flipping of the shell 3 and the battery cell 4 to a preset angle, turning the shell 3 to the bottom and the battery cell 4 to the top.

[0083] Step 4: Robot arm 2 sends the shelled battery cell 4 and shell 3 to the next process.
