Description

Technical Field

[0001] This invention relates to the field of lithium battery transfer technology in new energy vehicle manufacturing, and in particular to a clamping and transfer device for lithium battery production lines. Background Technology

[0002] In the field of new energy vehicles, lithium battery transfer devices are mainly used to improve production efficiency, ensure transportation safety, optimize space utilization, and adapt to the needs of multiple scenarios. They are an indispensable part of the entire life cycle management of lithium batteries.

[0003] A search revealed a Chinese invention patent with publication number CN113636339B, entitled "A Clamping and Transfer Device for a Lithium Battery Production Line." This patented device, when operating under negative pressure, uses a suction cup at the end of a corrugated hose to adsorb lithium batteries, facilitating battery adsorption and positioning. After moving to the transfer position, the negative pressure equipment increases suction, causing the corrugated hose to deform. This causes the lithium battery to contact a limit switch, closing the electronically controlled valve, thus resetting the return spring and allowing the battery to fall to its transported position, no longer affected by negative pressure. It utilizes the principle of air negative pressure and controls the negative pressure to clamp and remove lithium batteries. Compared to traditional mechanical clamping structures, it offers controllable adsorption force and avoids the stability issues that arise with long-term mechanical clamping. The drive motor mounted on the carrier is powered by a pantograph in conjunction with electrode posts during sliding, avoiding complicated wiring layouts and reducing wire laying and wear during operation.

[0004] However, this patented device causes lithium batteries to be clamped and blocked by the device during transfer and placement, preventing them from sticking tightly to other lithium batteries. This results in users having to frequently adjust the position of the lithium batteries, affecting the efficiency of the device in transferring and placing lithium batteries.

[0007] Preferably, the top of the slot is provided with an annular groove, the top of the annular groove is fixedly connected to a motor three, the output shaft of the motor three is fixedly connected to a rotating shaft located inside the annular groove, a gear is fixedly connected to the circumferential side of the rotating shaft, and a toothed ring aligned with the gear is fixedly connected to the inner wall of the circumferential side of the annular groove, and the circumferential side of the toothed ring is meshed with the circumferential side of the gear.

[0008] Preferably, at least four connecting posts are uniformly fixedly connected to the bottom of the toothed ring, and an extrusion block aligned with the telescopic block is fixedly connected to the circumferential side of the connecting post. The circumferential side of the extrusion block is slidably connected to the inner wall of the slotted circumferential side, and one end of the telescopic block abuts against the extrusion block.

[0009] Preferably, a limiting post aligned with the movable plate is fixedly connected to the inner wall of the side of the slot, the circumferential side of the limiting post is slidably connected to the inside of the movable plate, a spring surrounding the limiting post is fixedly connected between the side of the movable plate and the side of the slot, and limiting plates aligned with the movable plate are fixedly connected to the inner walls of both sides of the slot, the side of the limiting plate abuts against the side of the movable plate.

[0010] Preferably, a movable column is rotatably connected to the top of the transport body, the top of the movable column extends above the transport body, a rotating ring is fixedly connected to the outer wall of the circumferential side of the transport body, control grooves are evenly opened on the circumferential side of the rotating ring, a handle is fixedly connected between the two sides of the control groove, and at least four control button bodies are evenly fixedly connected to the circumferential side of the handle.

[0011] Preferably, openings are evenly provided between the two sides of the clamping plate, a soft sheet is fixedly connected to the side of the clamping plate, an inclined block is fixedly connected to the bottom of the soft sheet, and the side of the inclined block is fixedly connected to the side of the clamping plate.

[0012] Preferably, the bottom of the transfer body is provided with a lifting groove, the top inner wall of the lifting groove is fixedly connected to a motor, the output shaft of the motor is fixedly connected to a lead screw, and the circumferential side of the lead screw is threadedly connected to a lifting frame.

[0013] Preferably, the side of the lifting frame is slidably connected to the inner side wall of the lifting groove, and the two sides and the cooling surface of the lifting frame are fixedly connected to the extrusion frame. The bottom of the transfer body is evenly provided with storage grooves aligned with the extrusion frame, and the extrusion frame extends into the interior of the storage groove.

[0014] The beneficial effects of this invention are: 1. The device is connected to an external mobile device via a movable column using a clamping plate. The user holds the handle and moves the transporter, positioning it above the lithium battery so that the clamping plate surrounds it. Motor three is activated, causing the rotating shaft to rotate. This shaft, in turn, rotates the gear, which in turn rotates the gear ring. The gear ring then rotates the pressing block, which in turn moves the telescopic block, which in turn moves the moving plate. The moving plate then moves the clamping plate, securing the lithium battery. The user then moves the lithium battery horizontally and vertically to another location, placing it on a surface... When the device is near other lithium batteries, the main body is activated by pressing the control button. Motor 2 drives lead screw 2 to rotate, which in turn moves the moving frame. The moving frame, through the connecting frame, drives the clamping plate to rotate, causing the clamping plate near the already placed lithium battery to rotate to the bottom of the transport body. Then, the device presses the side of the lithium battery without clamping obstruction against the other lithium batteries, and activates motor 3 to reset the clamping plate. This helps prevent the lithium battery from being unable to press against other lithium batteries due to clamping or obstruction by the device, which would require the user to frequently adjust the position of the lithium battery and affect the efficiency of the device in transferring and placing lithium batteries.

[0015] 2. The flexible film, when the device clamps the lithium battery with the clamping plates, cushions the space between the clamping plates and the lithium battery. Simultaneously, the film fills the gaps between the clamping plates and the lithium battery, facilitating a smoother clamping of the plates and preventing damage to the lithium battery during handling and transport, thus improving the safety of the transport process. When the clamping plates approach and clamp the lithium battery, they move the inclined block, which lifts the lithium battery from its bottom, fixing it between one side of the two clamping plates and the top of the inclined block. When the user controls the second motor to rotate the clamping plates, multiple clamping plates can be simultaneously rotated away from the lithium battery, further preventing the clamping plates from obstructing the lithium battery and hindering the device from neatly placing the batteries together, thus improving the transport efficiency of the device.

[0016] 3. By setting up the extrusion frame, start motor one. Motor one drives screw one to rotate, screw one drives the lifting frame to move, and the lifting frame drives the extrusion frame to move. The extrusion frame presses against the top of the lithium battery. After the device controls the clamping plates in multiple directions to rotate away from the lithium battery, the extrusion frame, together with the remaining clamping plates and inclined blocks, clamps the lithium battery. This helps to improve the clamping effect of the device on the lithium battery, prevent the lithium battery from falling during the transfer process, and improve the stability of the device operation.

The circumferential side of the second lead screw 29 is threadedly connected to a movable frame 21. One side of the movable frame 21 is slidably connected to the inner wall of one side of the movable groove 28. A first fixed column 31 is fixedly connected between the bottom of the two sides of the movable frame 21. A connecting frame 30 is rotatably connected to the circumferential side of the first fixed column 31. A second fixed column 32 is rotatably connected between the two sides of the connecting frame 30. Both ends of the second fixed column 32 are fixedly connected to fixed plates. The side of the fixed plate is fixedly connected to the side of the clamping plate 10.

[0020] In this invention, a circular groove is provided at the top of the slot 6. A motor 17 is fixedly connected to the top of the circular groove. The output shaft of the motor 17 is fixedly connected to a rotating shaft 16 located inside the circular groove. A gear 18 is fixedly connected to the circumferential side of the rotating shaft 16. A toothed ring 4 aligned with the gear 18 is fixedly connected to the inner wall of the circumferential side of the circular groove. The circumferential side of the toothed ring 4 is meshed with the circumferential side of the gear 18.

[0021] At least four connecting posts 19 are evenly fixedly connected to the bottom of the toothed ring 4. An extrusion block 5 aligned with the telescopic block 8 is fixedly connected to the circumferential side of the connecting post 19. The circumferential side of the extrusion block 5 is slidably connected to the inner wall of the circumferential side of the slot 6. One end of the telescopic block 8 abuts against the extrusion block 5.

[0022] A limiting post 7 aligned with the movable plate 3 is fixedly connected to the inner side wall of the slot 6. The circumferential side of the limiting post 7 is slidably connected to the inside of the movable plate 3. A spring 13 is fixedly connected between the side of the movable plate 3 and the side of the slot 6, and a limiting plate 20 aligned with the movable plate 3 is fixedly connected to both inner walls of the slot 6. The side of the limiting plate 20 abuts against the side of the movable plate 3.

[0023] The top of the transport body 1 is rotatably connected to a movable column 2, the top of the movable column 2 extends above the transport body 1, and a rotating ring 14 is fixedly connected to the outer wall of the circumferential side of the transport body 1. Control grooves are evenly opened on the circumferential side of the rotating ring 14, and a handle 15 is fixedly connected between the two sides of the control groove. At least four control button bodies 34 are evenly fixedly connected to the circumferential side of the handle 15.

[0024] The clamping plate 10 has evenly spaced openings 9 between its two sides. A flexible sheet 12 is fixedly connected to the side of the clamping plate 10. An inclined block 11 is fixedly connected to the bottom of the flexible sheet 12. The side of the inclined block 11 is fixedly connected to the side of the clamping plate 10.

[0025] In use: The device is connected to an external mobile device via the movable column 2. The user holds the handle 15 to move the transport body 1, causing it to move above the lithium battery and surround the clamping plate 10 around it. The motor 17 is then activated, causing the rotating shaft 16 to rotate. The rotating shaft 16 drives the gear 18 to rotate, which in turn drives the gear ring 4 to rotate. The gear ring 4 drives the pressing block 5 to rotate, which in turn moves the telescopic block 8. The telescopic block 8 then moves the moving plate 3, which in turn moves the clamping plate 10, thus clamping the lithium battery. The user then moves the lithium battery to other locations by horizontal and vertical translation, placing the transferred lithium battery on a surface... When the lithium battery is next to other lithium batteries, the motor 27 is started by controlling the main body 34. The motor 27 drives the lead screw 29 to rotate, and the lead screw 29 drives the moving frame 21 to move. The moving frame 21 drives the clamping plate 10 to rotate through the connecting frame 30, so that the clamping plate 10 near the lithium battery is rotated to the bottom of the transfer body 1. Then the device will press the side of the lithium battery that is not blocked by the clamping plate 10 against the other lithium batteries, and start the motor 3 17 to reset the clamping plate 10. This helps to prevent the lithium battery from being unable to press against the other lithium batteries due to the clamping and obstruction of the device when transferring and placing lithium batteries, which would cause the user to frequently adjust the position of the lithium battery and affect the efficiency of the device in transferring and placing lithium batteries.

[0026] Example 2, refer to Figure 1-5 and Figure 7 A clamping and transfer device for a lithium battery production line includes a transfer body 1 with a lifting groove 22 at the bottom, a motor 23 fixedly connected to the top inner wall of the lifting groove 22, a lead screw 25 fixedly connected to the output shaft of the motor 23, and a lifting frame 24 threadedly connected to the circumferential side of the lead screw 25.

[0027] When the device is in use: when the clamping plate 10 holds the lithium battery, the soft sheet 12 buffers the space between the clamping plate 10 and the lithium battery. At the same time, the soft sheet 12 fills the gaps between the clamping plate 10 and the lithium battery, which facilitates the device to further and more smoothly clamp the clamping plate 10. This helps to prevent the lithium battery from being damaged during clamping and transportation, and improves the safety of the device during transportation. At the same time, when the clamping plate 10 approaches and clamps the lithium battery, the clamping plate 10 drives the inclined block 11 to move. The inclined block 11 lifts the lithium battery from the bottom, so that the lithium battery is fixed between one side of the two clamping plates 10 and the top of the inclined block 11. When the user controls the motor 27 to drive the clamping plate 10 to rotate, the clamping plates 10 in multiple directions can be rotated away from the lithium battery at the same time. This helps to further prevent the clamping plate 10 from blocking the lithium battery, which would prevent the device from neatly placing the lithium batteries together, and improves the transportation efficiency of the device.

[0028] Example 3, referring to Figure 1-6 A clamping and transfer device for a lithium battery production line includes a lifting frame 24 slidably connected to the inner wall of the side of a lifting groove 22, and extrusion frames 26 fixedly connected to both sides and the cool side of the lifting frame 24. The bottom of the transfer body 1 is evenly provided with storage grooves aligned with the extrusion frames 26, and the extrusion frames 26 extend into the interior of the storage grooves.

[0029] When using this invention: start motor 23, motor 23 drives lead screw 25 to rotate, lead screw 25 drives lifting frame 24 to move, lifting frame 24 drives pressing frame 26 to move, pressing frame 26 presses on the top of lithium battery. After the device controls the clamping plates 10 in multiple directions to rotate away from lithium battery, pressing frame 26, together with the remaining clamping plates 10 and inclined block 11, clamps the lithium battery, which helps to improve the clamping effect of the device on lithium battery, prevents lithium battery from falling during transportation, and improves the stability of device operation.
