Description

Technical Field

[0001] This invention relates to the field of battery cell processing technology, specifically to a battery cell polarity reversal device. Background Technology

[0002] When processing battery cells, it is usually necessary to inspect them for various parameters such as visual inspection, thickness, and height. However, after the battery cells are inspected, since they are usually placed vertically, in order to facilitate subsequent processing, a corresponding battery cell polarity reversal device is usually used to flip the vertically placed battery cells and place them on the conveyor line for subsequent transmission and processing.

[0003] For example, the battery cell flipping device and processing equipment with announcement number CN223213240U includes a support mechanism; a synchronous flipping mechanism is set on the support mechanism, and the synchronous flipping mechanism includes multiple clamping rotation components, a synchronous linkage component and a tension adjustment component. The synchronous linkage component is connected to the multiple clamping rotation components and the tension adjustment component, and the synchronous linkage component and the tension adjustment component can drive the multiple clamping rotation components holding the battery cell to flip synchronously.

[0004] The existing technology has the following technical problems: When the existing battery cell flipping device clamps and flips the battery cell, it achieves clamping of the battery cell by the relative movement of two plate-shaped components. Although it can clamp the battery cell, the plate-shaped components cannot effectively adapt to the limiting of rectangular or cylindrical battery cells. When the plate-shaped components clamp a cylindrical battery cell, the contact area between the arc surface of the cylindrical battery cell and the plane of the plate-shaped components is small, which can easily cause the battery cell to fall off during the flipping process.

[0005] Therefore, we propose a cell polarity reversal device to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a battery cell polarity reversal device to solve the problem mentioned in the background art. In existing battery cell reversal devices on the market, the clamping and reversing of the battery cell is achieved by the relative movement of two plate-shaped components. Although the plate-shaped components can clamp the battery cell, they cannot effectively adapt to the limiting of rectangular or cylindrical battery cells. When the plate-shaped components clamp a cylindrical battery cell, the small contact area between the arc surface of the cylindrical battery cell and the plane of the plate-shaped components easily leads to the battery cell falling off during the reversal process.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a battery cell polarity reversing device, comprising a reversing module mounted on a support base, the reversing module being used to reverse vertically placed battery cells and place the reversed battery cells onto a second conveyor line for transmission, the reversing module comprising a lifting guide rail, and a rotary cylinder mounted on the lifting guide rail, the output end of the rotary cylinder being mounted with a locking seat, and a power cylinder being fixed in the middle of the locking seat, the telescopic end of the power cylinder being mounted with a pressing block, and a movable block being mounted on the side of the pressing block, the movable block being interconnected by an auxiliary spring and a receiving block, and an adjusting clamping arm being fixed on the side of the movable block, the adjusting clamping arm being mounted with a positioning unit and a movable unit, the distance between the movable unit and the positioning unit being adjusted to accommodate battery cells with different cross-sectional shapes for positioning.

[0008] Preferably, a gantry frame is provided on the side of the flipping module, and a mechanical gripper is installed on the gantry frame. A cell transmission line is provided on the right side of the gantry frame, and a transverse module is provided on the side of the cell transmission line. A clamping component is installed on the transverse module, and a barcode scanning module, a height detection module, and a thickness measurement module for detecting cell parameters are provided on the side of the clamping component. The mechanical gripper on the gantry frame is used to clamp and transfer the tested cells. The mechanical gripper transfers the qualified cells to the flipping module, and can also transfer the unqualified cells to the first conveyor line.

[0009] By adopting the above technical solution, and by setting up a gantry frame and a mechanical gripper, it is possible to easily clamp and transfer qualified or unqualified battery cells.

[0010] Preferably, the clamping component includes a movable seat that can move on the transverse module, a limit cylinder is installed on the movable seat, and a positioning gripper is fixed to the telescopic end of the positioning gripper.

[0011] By adopting the above technical solution, the movement of the movable seat on the transverse module facilitates the transfer of battery cells to various testing stations.

[0012] Preferably, the contact surfaces of both the extrusion block and the movable block are set as inclined surfaces, and the movable block is symmetrically arranged about the transverse central axis of the extrusion block. The movable block forms an elastic telescopic structure through an auxiliary spring and a receiving block.

[0013] By adopting the above technical solution, when the extrusion block is pushed by the power cylinder, the inclined surface of the extrusion block can be used to push the inclined surface of the movable block, so that the movable block can move inside the receiving block.

[0014] Preferably, a support plate fixed on the accommodating block is provided between the regulating clamping arms on both sides of the accommodating block. The support plate is used to support the bottom of the battery cell. The positioning unit and the moving unit on the regulating clamping arm are both set as cylindrical structures.

[0015] By adopting the above technical solution, the bottom of the battery cell can be supported by the tray, which facilitates the subsequent clamping and limiting of the battery cell by the control arms on both sides.

[0016] Preferably, a movable plate is fixed on the movable unit, and the movable plate is connected to the control clamp arm by a first spring. A first electromagnet is fixed inside the control clamp arm on the side of the movable plate, and a first magnetic block is embedded on the side of the movable plate that is in contact with the first electromagnet. A limit control plate is provided between the movable unit and the positioning unit, and the end of the limit control plate away from the movable unit is connected to the control clamp arm by a second spring. A second magnetic block is embedded on the end of the limit control plate that extends into the control clamp arm, and a second electromagnet fixed inside the control clamp arm is provided on the side of the second magnetic block.

[0017] By adopting the above technical solution, the setting of the second spring enables the limit control plate to reset and rebound after it moves on the control arm.

[0018] Preferably, the movable plate on the active unit can slide on the control arm, and the positioning unit is fixed on the control arm. When the first electromagnet is energized, it can generate a magnetic attraction force on the first magnetic block on the movable plate, and when the second electromagnet is energized, it can generate a magnetic attraction force on the second magnetic block on the limit control plate.

[0019] By adopting the above technical solution, the movement of the moving unit and the limit control plate can be controlled by setting up an electromagnet.

[0020] Preferably, the limiting control plate and the control clamp arm are slidably connected, and the side of the limiting control plate located outside the control clamp arm is set to be arc-shaped. The side of the limiting control plate located outside the control clamp arm is close to the movable unit, so that it can squeeze the movable unit when moving towards the control clamp arm. The side of the limiting control plate located outside the control clamp arm is close to the positioning unit, so that it does not contact the positioning unit when moving towards the control clamp arm.

[0021] By adopting the above technical solution, the movable unit can be pushed to move on the control arm by the pressure of the limit control plate, thereby changing the distance between the movable unit and the positioning unit.

[0022] Preferably, the positioning unit and the moving unit are located on the same horizontal line, and the surface of the limiting control plate extending outside the control arm is flush with the positioning unit and the moving unit in the initial state.

[0023] By adopting the above technical solution and setting the limit control plate, the contact area when clamping the side of the rectangular battery cell can be increased.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the cell polarity reversing device, by setting the clamping arm as a movable and adjustable component, can effectively make adjustments when facing cell reversing with different cross-sectional shapes through the movable adjustment of the clamping arm, thereby improving the adaptability of the clamping arm to the cell clamping. 1. The movement of the moving seat is controlled by the transverse module, so that the clamped battery cells are placed sequentially into the barcode scanning module, height detection module and thickness measurement module for parameter detection. After the battery cell parameters are detected, the mechanical gripper is controlled by the gantry frame to move and clamp the tested battery cells. The unqualified battery cells are clamped and sent to the first conveyor line for transmission, thereby improving the automation level of battery cell detection. 2. By adjusting the movement of the clamping arm, the side of the rectangular battery cell can be clamped using the movable unit, positioning unit, and limit control plate. The limit control plate increases the contact area with the side of the rectangular battery cell. At the same time, when the limit control plate moves under the action of magnetic force, it can also squeeze the movable unit, thereby changing the distance between the movable unit and the positioning unit. This adapts to the clamping and limiting of the side of the cylindrical battery cell, improving the stability of the limiting of the cylindrical battery cell. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figures 1-10Existing battery cell flipping devices clamp and flip the battery cells by the relative movement of two plate-shaped components. While this clamps the cells, the plate-shaped components cannot effectively accommodate rectangular or cylindrical battery cells. When clamping cylindrical battery cells, the small contact area between the curved surface of the cylindrical battery cell and the plane of the plate-shaped component makes it easy for the battery cell to fall off during the flipping process. To solve this technical problem, this embodiment discloses the following technical content: a battery cell polarity flipping device, including a flipping module 11 mounted on a support base 1. The flipping module 11 is used to flip vertically placed battery cells and place the flipped battery cells onto a second conveyor line 12 for transmission. The flipping module 11 includes a lifting mechanism. A lowering guide rail 111 is provided, and a rotary cylinder 112 is mounted on the lifting guide rail 111. A locking seat 113 is mounted on the output end of the rotary cylinder 112, and a power cylinder 114 is fixed in the middle of the locking seat 113. A pressing block 115 is mounted on the telescopic end of the power cylinder 114, and a movable block 116 is mounted on the side of the pressing block 115. The movable block 116 is connected to the receiving block 118 by an auxiliary spring 117, and an adjusting clamping arm 119 is fixed on the side of the movable block 116. A positioning unit 13 and a movable unit 14 are mounted on the adjusting clamping arm 119. The distance between the movable unit 14 and the positioning unit 13 is adjusted to accommodate the limiting of battery cells with different cross-sectional shapes. The contact surfaces of the pressing block 115 and the movable block 116 are both set as inclined surfaces. Furthermore, the movable block 116 is symmetrically arranged about the transverse central axis of the pressing block 115. The movable block 116 forms an elastic telescopic structure through the auxiliary spring 117 and the accommodating block 118. A support plate 1110 fixed on the accommodating block 118 is provided between the regulating clamping arms 119 on both sides of the accommodating block 118. The support plate 1110 is used to support the bottom of the battery cell. The positioning unit 13 and the movable unit 14 on the regulating clamping arm 119 are both set as cylindrical structures. A movable plate 15 is fixed on the movable unit 14, and the movable plate 15 is connected to the regulating clamping arm 119 through the first spring 16. A first electromagnet 18 fixed inside the regulating clamping arm 119 is provided on the side of the movable plate 15, and a first electromagnet is embedded on the side of the movable plate 15 that is in contact with the first electromagnet 18. A limit control plate 19 is provided between block 17, movable unit 14, and positioning unit 13. The end of the limit control plate 19 away from movable unit 14 is connected to the control arm 119 via a second spring 20. A second magnetic block 21 is embedded in the end of the limit control plate 19 that extends into the control arm 119. A second electromagnet 22 is fixed inside the control arm 119 on the side of the second magnetic block 21. The movable plate 15 on movable unit 14 can slide on the control arm 119, and positioning unit 13 is fixed on the control arm 119. When the first electromagnet 18 is energized, it can generate a magnetic attraction force on the first magnetic block 17 on movable plate 15. When the second electromagnet 22 is energized, it can generate a magnetic attraction force on the second magnetic block 21 on limit control plate 19.The limiting control plate 19 and the controlling clamp arm 119 are slidably connected. One end of the limiting control plate 19 outside the controlling clamp arm 119 is arc-shaped. This end of the limiting control plate 19, located near the movable unit 14, can press against the movable unit 14 when moving towards the controlling clamp arm 119. The other end of the limiting control plate 19, located near the positioning unit 13, does not contact the positioning unit 13 when moving towards the controlling clamp arm 119. The positioning unit 13 and the movable unit 14 are on the same horizontal line, and the surface of the limiting control plate 19 extending beyond the controlling clamp arm 119 is initially flush with both the positioning unit 13 and the movable unit 14.

[0029] When it is necessary to flip the rectangular battery cell, the opening of the power cylinder 114 can move the pressing block 115. After the pressing block 115 moves, it can use its inclined side to press the movable block 116. At this time, the movable block 116 and the adjusting clamping arm 119 move outward toward the receiving block 118. After the movable block 116 moves, the auxiliary spring 117 is compressed. Then, the battery cell is placed on the tray 1110 on the receiving block 118. The power cylinder 114 controls the pressing block 115 to retract. At this time, the movable block 116 and the adjusting clamping arm 119 are reset and spring back under the action of the auxiliary spring 117. After resetting, the adjusting clamping arm 119 clamps and fixes the side of the rectangular battery cell through the movable unit 14, the positioning unit 13 and the limit adjusting plate 19 on it. Since the limit adjusting plate 19 is flush with the movable unit 14 and the positioning unit 13 in the initial state, the limit adjusting plate 19 can increase the contact area with the side of the rectangular battery cell. After the battery cell is limited, the rotating cylinder 112 controls the card holder 113 to rotate, thereby flipping the limited battery cell and placing it on the second conveyor line 12 on the side for conveying. When flipping the cylindrical battery cell, the second electromagnet 22 is first activated. After activation, the second electromagnet 22 generates a magnetic attraction force on the second magnetic block 21 at the end of the limit adjustment plate 19. At this time, the limit adjustment plate 19 moves towards the outside of the adjustment clamp arm 119. After moving, the limit adjustment plate 19 uses its arc surface to press the movable unit 14, causing it to move away from the positioning unit 13, increasing the distance between the positioning unit 13 and the movable unit 14. After adjusting the movable unit 14, the first electromagnet 18 is activated. The first electromagnet 18, when energized, attracts the first magnetic block 17 on the moving plate 15, thus fixing the position of the moved movable unit 14. The increased distance between the movable unit 14 and the positioning unit 13 improves the stability of the cylindrical battery's positioning, preventing poor positioning stability due to insufficient contact area when the planar structure positions the cylindrical battery. The specific positioning state is as follows: Figure 9 and Figure 10 As shown.

[0030] Example 2: The technical content disclosed in this example is a further improvement based on Example 1 described above. The following technical content is disclosed in this example: Figures 1-5 As shown, a gantry frame 8 is provided on the side of the flipping module 11, and a mechanical gripper 9 is installed on the gantry frame 8. A cell transmission line 2 is provided on the right side of the gantry frame 8, and a transverse module 3 is provided on the side of the cell transmission line 2. A clamping component 4 is installed on the transverse module 3, and a barcode scanning module 5, a height detection module 6, and a thickness measurement module 7 for detecting cell parameters are provided on the side of the clamping component 4. The mechanical gripper 9 on the gantry frame 8 is used to clamp and transfer the tested cells. The mechanical gripper 9 transfers the tested qualified cells to the flipping module 11, and can also transfer unqualified cells to the first conveyor line 10. The clamping component 4 includes a movable seat 401, which can move on the transverse module 3. A limit cylinder 402 is installed on the movable seat 401, and a positioning gripper 403 is fixed at the telescopic end of the positioning gripper 403.

[0031] During battery cell processing, the battery cells are transported via battery cell transmission line 2. The lateral movement module 3 controls the movement of the moving seat 401. The opening of the limit cylinder 402 clamps the battery cells via the positioning gripper 403. Then, the lateral movement module 3 controls the movement of the moving seat 401, thereby placing the clamped battery cells sequentially into the barcode scanning module 5, height detection module 6, and thickness measurement module 7 for parameter detection. After the battery cell parameters are detected, the gantry frame 8 controls the movement of the mechanical gripper 9, which clamps and delivers the detected battery cells. Defective battery cells are clamped and sent to the first conveyor line 10 for transmission.
