Description

Technical Field

[0001] This application relates to the technical field of battery cell edge passivation processing production line, and in particular to a battery cell replacement anti-tipping device for a battery cell edge passivation processing production line. Background Technology

[0002] After solar cells are cut, the edges contain numerous dangling bonds and defects, which can become recombination centers for charge carriers (electrons and holes), leading to current loss. To improve photoelectric conversion efficiency, the edges of the solar cells need to be passivated. Specifically, this is achieved by depositing aluminum dioxide to saturate the dangling bonds at the edges, reducing the probability of charge carrier recombination and thus improving photoelectric conversion efficiency.

[0003] Figure 1 The fixture 01 is a type of fixture in the prior art, and the fixture 01 has a base 011 for supporting the battery cells.

[0004] During the processing, the battery cells are taken out of the aluminum boat and placed in the material box. The battery cells need to be removed, tested, sorted and loaded. During this process, a robot arm is used to remove the battery cells and the base from the material box and place them in the fixed seat at the designated work station.

[0005] However, with prolonged use, it's inevitable that the battery cells and bases transported by the robotic arm may shift or deviate in position. This necessitates personnel entering the equipment to correct the cells and bases. To accommodate the stacked battery cells, the mounting base requires restraint rods around its perimeter. These rods must both restrict the battery cells and ensure they don't obstruct the robotic arm's operation. To facilitate correction, a lifting mechanism is needed beneath the worktable. However, this prevents the mounting base from being fixed to the worktable, requiring horizontal positioning via pins or similar components, resulting in lower stability in the width direction. During troubleshooting, personnel are prone to accidentally touching the mounting base, causing it to tilt or fall in the width direction, potentially affecting adjacent mounting bases. Therefore, it's necessary to improve the restraint mechanism of the mounting base. Summary of the Invention

[0006] To improve the stability of the mounting base, this application provides a battery cell replacement anti-tipping device for a battery cell edge passivation processing production line.

[0007] This application provides a battery cell replacement anti-tipping device for a battery cell edge passivation processing production line, which adopts the following technical solution: A battery cell edge passivation processing production line includes a battery cell replacement anti-tipping device, comprising a workbench, a lifting assembly below the workbench, a lifting plate connected to the output end of the lifting assembly, and several hooks passing through the lifting plate. The hooks are rotatably connected to the lifting plate, and the rotation direction of the hooks is parallel to the length direction of the fixed base. Grooves are provided at the four corners of the fixed base, and the width of the grooves is the same as the width of the hooks. When stable, the hooks are located in the grooves and are in a vertical state. The lifting assembly is used to raise the lifting plate.

[0008] By adopting the above technical solution, during stabilization, the lifting assembly raises the lifting plate. During this process, the hook claws rotate against the groove until the lifting plate raises the fixing seat. At this point, the hook claws return to a vertical position and contact the inner wall of the groove, achieving the effect of stabilizing the fixing seat. Through the cooperation of the hook claws and the groove, and the hook claw design targeting the width direction of the fixing seat, the possibility of the fixing seat flipping in its width direction is reduced, thus improving the stability of the fixing seat.

[0009] Optionally, a rotating column is rotatably connected to the lifting plate, the rotating column is located above the lifting plate, and the distance between the top end of the hook and the rotating column is less than the distance between the bottom end of the hook and the rotating column.

[0010] By adopting the above technical solution, and by setting a rotating column above the lifting plate, it is ensured that the torque of the lower part of the hook is longer than that of the upper part, so that the center of gravity of the hook is lower, ensuring that the hook can automatically return to the vertical position in its natural state, and allowing the hook to smoothly enter the trench.

[0011] Optionally, the lifting plate is provided with a pad and a locking assembly. Several positioning posts are connected to the top wall of the pad. The top of the positioning post is shaped like a frustum, with the smaller end located at the highest point. The output end of the lifting assembly is connected to an extension post. The lifting plate is connected to the top of the extension post through the locking assembly.

[0012] By adopting the above technical solution, when the battery cell shifts within the mounting bracket, the base will also shift. When the lifting plate is raised, it will lift the mounting bracket, at which point the positioning pin will be inserted into the positioning hole to correct the relative position and angle between the base and the mounting bracket.

[0013] Optionally, the locking assembly includes a locking bolt, the pad is connected to the lifting plate, the locking bolt passes through the pad, the lifting plate and the extension post, and is threadedly engaged with the extension post.

[0014] By adopting the above technical solution, when installing the lifting plate, the locking bolts are threaded onto the extension column to press the pads together, thereby achieving the installation of the lifting plate.

[0015] Optionally, the locking assembly includes hooks, several of which are connected to the lifting plate. Several locking slots are provided on the extension column. The lifting plate is connected to the top of the extension column by the hooks engaging with the locking slots. The lifting plate is provided with an unlocking assembly that disengages the hooks from the locking slots.

[0016] By adopting the above technical solution, during installation, the hook is engaged in the slot to install the lifting plate. During unlocking, the hook is deformed by the unlocking component to disengage from the slot, thus unlocking the hook.

[0017] Optionally, the unlocking assembly includes a push block, a push rod, and a return spring. A fixed plate is connected to the lifting plate, the push rod is connected to the push block, and the push block slides with the fixed plate through the push rod. A retaining ring is connected to the push rod, and the retaining ring abuts against the fixed plate. The return spring is connected to the push rod and is located between the fixed plate and the push block. The push rod faces the pawl. When unlocking, the push rod abuts against the pawl, and the return spring is in a compressed state.

[0018] By adopting the above technical solution, when unlocking, pushing the push block moves the push rod, compresses the reset spring, and the push rod contacts the hook claw, causing the hook claw to deform, thus disengaging the hook claw from the locking groove and achieving the effect of unlocking the lifting plate.

[0019] Optionally, the lifting assembly includes a sliding table, a lifting electric cylinder, a lifting base, and a rodless cylinder. Several rows of fixed bases are arranged on the worktable, with several fixed bases in each row. The top of the sliding table is slidably fitted onto the bottom wall of the worktable. A driving assembly for moving the sliding table is provided on the worktable. The lifting electric cylinder is vertically mounted on the sliding table. The lifting base is connected to the moving end of the lifting electric cylinder. The rodless cylinder is mounted on the lifting base, and its output direction is perpendicular to the lifting electric cylinder. The extension column is connected to the moving end of the rodless cylinder.

[0020] By adopting the above technical solution, when lifting the fixed seat, the lifting electric cylinder is activated, causing the sliding table to rise, which in turn drives the rodless cylinder to rise, causing the extension column to rise, which in turn drives the lifting plate to rise until the lifting plate touches the fixed seat and continues to rise. The hook claw then stabilizes the fixed seat, achieving a stable lifting effect. If it is necessary to lift another row of fixed seats, the horizontal cylinder can be activated to move the extension column to below the other row of fixed seats.

[0021] Optionally, the drive assembly includes a drive motor, a drive gear, and a fixed rack. The fixed rack is connected to the bottom wall of the worktable and is parallel to the distribution direction of each row of fixed seats. The drive motor is mounted on the sliding table, and the drive gear is connected to the output shaft of the drive motor and meshes with the fixed rack.

[0022] By adopting the above technical solution, when it is necessary to lift other fixed seats in the same row, the drive motor is started to make the drive gear rotate. Through the cooperation of the drive gear and the fixed rack, the sliding table is moved to the bottom of the designated fixed seat, thus achieving the effect of moving the sliding table.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. During stabilization, the lifting plate is raised using the lifting assembly. During this process, the hooks rotate against the groove until the lifting plate lifts the fixing seat. At this point, the hooks return to a vertical position and contact the inner wall of the groove, thus stabilizing the fixing seat. Through the cooperation of the hooks and the groove, and considering the width direction of the fixing seat, the hook design reduces the possibility of the fixing seat flipping in that direction, thereby improving its stability. 2. When unlocking, push the push block to move the push rod. The reset spring is compressed, and the push rod contacts the hook, causing the hook to deform and disengage from the locking slot, thus unlocking the lifting plate. Attached Figure Description

Detailed Implementation

[0032] The following is in conjunction with the appendix Figures 2-7 This application will be described in further detail.

[0033] Embodiment 1 of this application discloses a battery cell replacement anti-tipping device for a battery cell edge passivation processing production line. (Refer to...) Figure 2 The anti-tipping device for battery cell edge passivation processing production line includes a workbench 1 and several rows of fixed seats 01 arranged on the workbench 1. In this embodiment, two rows are used as an example, and three fixed seats 01 are arranged in each row. The fixed seats 01 are restricted to the workbench 1 by positioning pins. Several lifting slots are opened on the workbench 1, and the lifting slots correspond one-to-one with the fixed seats 01 and are located directly below the fixed seats 01.

[0034] Reference Figure 2 and Figure 3 A lifting assembly 2 is provided below the worktable 1. The lifting assembly 2 includes a sliding table 21, a lifting electric cylinder 22, a lifting seat 23, and a rodless cylinder 24. Two sliding rails are fixedly connected to the bottom wall of the worktable 1. The sliding rails are parallel to the length direction of the worktable 1, and the sliding table 21 is slidably engaged on the sliding rails.

[0035] Reference Figure 2 A drive assembly 3 is provided on the sliding table 21. The drive assembly 3 includes a drive motor 31, a drive gear 32, and a fixed rack 33. The drive motor 31 is mounted on the sliding table 21, and the drive gear 32 is mounted on the output shaft of the drive motor 31. The fixed rack 33 is fixedly connected to the bottom wall of the sliding table 21 and is parallel to the sliding rail. The drive gear 32 meshes with the fixed rack 33.

[0036] Reference Figure 3 The lifting seat 23 is vertically slidably fitted onto the sliding table 21. The lifting electric cylinder 22 is vertically mounted on the sliding table 21, and the lifting seat 23 is fixedly connected to the moving end of the lifting electric cylinder 22. The rodless cylinder 24 is fixedly connected to the lifting seat 23, and its conveying direction is perpendicular to the fixed rack 33. An extension column 241 is fixedly connected to the moving end of the rodless cylinder 24, and the extension column 241 is vertically arranged.

[0037] Reference Figure 4 and Figure 5 The extension column 241 has a lifting plate 4 and a locking assembly 5 at its top. The lifting plate 4 is a rectangular plate with a pad 41 fixedly connected to its surface. Several positioning posts 42 are threaded onto the top wall of the pad 41. In this embodiment, two are used as an example. The top of the positioning post 42 is truncated cone-shaped, with the smaller end located at the highest point. A base 011 for supporting the battery cell is provided inside the fixing seat 01. The base 011 is inserted into the positioning post 42. The positioning post 42 is used to correct the base 011 that supports the battery cell. The locking assembly 5 includes a locking bolt 51, which passes through the pad 41, the lifting plate 4, and the top of the extension column 241, and is threaded onto the extension column 241.

[0038] Reference Figure 4 and Figure 5 Several rotating columns are rotatably connected to the pad 41, and the rotating columns are located above the lifting plate 4. In this embodiment, four columns are used as an example. Hooks 43 are rotatably connected to the rotating columns. The fixing base 01 is rectangular, and grooves 012 are provided at each of the four corners of the fixing base 01. The width of the grooves 012 is the same as the width of the hooks 43. The hooks 43 are vertically arranged in the normal state, and the distance between the top of the hook 43 and the rotating shaft is less than the distance between the bottom of the hook 43 and the rotating shaft.

[0039] The implementation principle of the anti-tipping device for battery cell edge passivation processing production line in Embodiment 1 of this application is as follows: When checking the battery cells, the drive motor 31 is started, causing the drive gear 32 to rotate, so that the sliding table 21 moves directly below the designated fixed seat 01. The lifting cylinder 22 is started, so that the lifting seat 23 rises, the lifting plate 4 rises, and the hook 43 rotates after contacting the groove 012 until the lifting plate 4 contacts the bottom wall of the fixed seat 01 and pushes the fixed seat 01 out. At this time, the hook 43 automatically returns to the vertical state and fits into the groove 012 to stabilize the fixed seat 01. At the same time, the positioning column 42 is inserted into the bottom of the base 011 to correct the position of the base 011. At this time, the operator can manually calibrate the battery cells.

[0040] By cooperating with the hook 43 and the groove 012, and with the hook 43 designed for the width direction of the fixed seat 01, the possibility of the fixed seat 01 flipping in its width direction is reduced, thereby improving the stability of the fixed seat 01.

[0041] Example 2: The difference between this example and Example 1 is that the structure of the locking component 5 is different.

[0042] Reference Figure 6 and Figure 7 The locking assembly 5 includes two hooks 52, which are fixedly connected to the bottom wall of the lifting plate 4 and are arranged opposite to each other. An extension plate is fixedly connected to the extension column 241, and a snap-fit ​​groove is opened on the extension plate. The hooks 52 pass through the snap-fit ​​groove and engage with it.

[0043] Reference Figure 6 and Figure 7 An unlocking assembly 6 is provided on the lifting plate 4, which includes a push block 61, a push rod 62, and a return spring 63. A fixed plate is fixedly connected to the bottom wall of the lifting plate 4. The push rod 62 is a rectangular rod that passes through the fixed plate and aligns with the hook 52. A retaining ring 621 is fixedly connected to the push rod 62, which abuts against the fixed plate and is located between the fixed plate and the hook 52. The push block 61 is fixedly connected to the end of the push rod 62, and the return spring 63 is sleeved on the push rod 62 and located between the fixed plate and the push block 61.

[0044] During installation, the lifting plate 4 is installed on the top of the extension column 241 through the cooperation of the hook 52 and the locking groove; when unlocking, push the push block 61 to move the push rod 62, and the return spring 63 is compressed until the push rod 62 presses the hook 52, the hook 52 deforms, and the end of the locking groove disengages from the hook 52, so the lifting plate 4 can be removed.

[0045] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
