Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, specifically to a battery core packaging device. Background Technology

[0002] Existing battery processing equipment, after winding the battery core, places it into a folded aluminum-plastic film, and then seals both sides of the film using a sealing device. Current aluminum-plastic film sealing machines involve multiple steps—operators placing the film around the battery core and then starting the machine—which reduces the efficiency of the sealing process. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a battery core packaging device. The specific technical solution of this utility model is as follows:

[0004] A battery core packaging device includes: a worktable, a motor, a rotating plate, a placement component, a pressing component, a first detection sensor, a second detection sensor, a first cylinder, a first packaging component, and a second packaging component. The motor is located at the bottom of the worktable. The rotating plate is rotatably mounted on the worktable and connected to the rotating shaft of the motor. The placement component is located on the rotating plate and is used to place the battery core wrapped in aluminum-plastic film. The pressing component is used to press the battery core wrapped in aluminum-plastic film onto the placement component. The first cylinder is used to lift the pressing component. The first and second packaging components are located on the worktable. The first detection sensor is used to detect whether the pressing component has been lifted. The second detection sensor is used to detect whether the operator has moved away from the rotating plate. The first and second packaging components are located on the worktable and are respectively used to package different sides of the aluminum-plastic film.

[0005] Furthermore, the pressing component includes a support block, a rotating rod, and a pressing block. The support block is fixedly mounted on the rotating plate. One end of the rotating rod is rotatably mounted on the support block and performs lever movement with the support block as the fulcrum. The other end is fixedly connected to the pressing block. The pressing block is used to press the battery core wrapped with aluminum-plastic film onto the placement component.

[0006] Furthermore, the workbench includes a first support, and the first cylinder is vertically mounted on the first support. The first cylinder presses the end of the rotating rod connected to the support block by extending the piston rod, so that the rotating rod lifts the pressing block.

[0007] Furthermore, the first detection sensor is a Hall sensor, which is mounted on the first bracket, and a magnet is provided at the bottom of the pressing block.

[0008] Furthermore, the rotating plate is square, and the number of placement components and pressing components is the same. There are four placement components, which are respectively set at the four corners of the square rotating plate. Each placement component is provided with a stop block and mutually perpendicular pads. The pads cooperate with the first sealing component and the second sealing component to seal different sides of the aluminum-plastic film.

[0009] Furthermore, the workbench includes a second support, and the first packaging component and the second packaging component have the same structure. The first packaging component includes a second cylinder, a connecting block and a packaging block. The second cylinder is vertically mounted on the second support, and the piston rod of the second cylinder is connected to the packaging block through the connecting block.

[0010] Furthermore, the workbench includes a vertical rod, and the second detection sensor is a human infrared detection sensor, which is mounted on the vertical rod.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: The packaging device described in this application detects that the pressing component presses the battery core wrapped in aluminum-plastic film onto the placement component through the first detection sensor, and then controls the rotation of the turntable only after the second detection sensor detects that the operator has left the turntable, so that the first packaging component and the second packaging component can package different sides of the aluminum-plastic film, thereby improving the working efficiency of the packaging device; if any detection sensor fails to detect the corresponding signal, the turntable will not rotate, which improves the working efficiency of the packaging device and also improves the safety of the operation.

[0023] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] like Figures 1 to 6 As shown, a battery core packaging device includes: a workbench 1, a motor, a rotating plate 2, a placement component 3, a pressing component, a first detection sensor 4, a second detection sensor 5, a first cylinder 6, a first packaging component, and a second packaging component. The motor (located in the workbench 1, a common mechanical connection structure, not shown) is located at the bottom of the workbench 1. The rotating plate 2 is rotatably mounted on the workbench 1 and connected to the rotating shaft of the motor. The placement component 3 is mounted on the rotating plate 2 and is used to place the battery core wrapped in aluminum-plastic film. The pressing component is used to press the battery core wrapped in aluminum-plastic film onto the placement component 3. The first cylinder 6 is used to lift the pressing component. The first and second packaging components are mounted on the workbench 1. The first detection sensor 4 is used to detect whether the pressing component has been lifted. The second detection sensor 5 is used to detect whether the operator has moved away from the rotating plate 2. The first and second packaging components are mounted on the workbench 1 and are respectively used to package different sides of the aluminum-plastic film.

[0025] In one embodiment, the pressing component includes a support block 7, a rotating rod 8, and a pressing block 9. The support block 7 is fixedly mounted on the rotating plate 2. One end of the rotating rod 8 is rotatably mounted on the support block 7, with a portion extending beyond the support block 7 to perform lever motion with the support block 7 as a fulcrum. The other end is fixedly connected to the pressing block 9. The pressing block 9 is used to press the battery core wrapped in aluminum-plastic film onto the placement component 3. The friction between the rotating rod 8 and the support block 7 is relatively large, and the rotating rod 8 needs an external force to perform lever motion with the support block 7 as a fulcrum. The pressing block 9 presses the battery core wrapped in aluminum-plastic film onto the placement component 3 through gravity and the friction of the rotating rod 8.

[0026] In one embodiment, the workbench 1 includes a first support 10, and a first cylinder 6 is vertically mounted on the first support 10. The first cylinder 6 extends its piston rod to press one end of the rotating rod 8 connected to the support block 7, causing the rotating rod 8 to lift the pressing block 9. The support block 7 divides the rotating rod 8 into a long end and a short end. The top end of the long end is fixedly connected to the pressing plate. During the rotation of the rotating plate 2, the short end of the rotating rod 8 of the pressing component will alternately come to the direct under of the first cylinder 6. At this time, the first cylinder 6 extends its piston rod and presses down on the short end of the rotating rod 8, causing the rotating rod 8 to perform a lever movement and lift the pressing plate connected to the long end.

[0027] In one embodiment, the first detection sensor 4 is a Hall sensor, which is mounted on the first bracket 10, and a magnet 11 is provided at the bottom of the pressing block 9. The first detection sensor 4 can also be a proximity sensor, in which an iron block can be provided on the pressing plate or the rotating rod 8 can be fixed to the pressing plate by metal screws. As long as the pressing plate is close, the proximity sensor can detect a signal.

[0028] In one embodiment, the rotating plate 2 is square, and the number of placement components 3 is the same as the number of pressing components, with four placement components 3 respectively located at the four corners of the square rotating plate 2. Each placement component 3 has a stop block 12 and mutually perpendicular pads 13, which cooperate with the first and second encapsulation components to encapsulate different sides of the aluminum-plastic film. The two sides of the placement components 3 extend out of the rotating plate 2, providing effective support for the first and second encapsulation components during aluminum-plastic film encapsulation. The stop blocks 12 act as limiters, ensuring accurate placement of the battery core wrapped in aluminum-plastic film onto the placement components 3. The pads 13 improve encapsulation quality.

[0029] In one embodiment, the workbench 1 includes a second support 14. The first and second packaging components have identical structures. The first packaging component includes a second cylinder 15, a connecting block 16, and a packaging block 17. The second cylinder 15 is vertically mounted downwards on the second support 14, and its piston rod is connected to the packaging block 17 via the connecting block 16. The first and second packaging components are arranged side-by-side on the second support 14. One component packages the left or right side of the battery core wrapped in aluminum-plastic film, while the other packages the bottom side of the battery core wrapped in aluminum-plastic film. Both components work simultaneously. The left or right side of the battery core wrapped in aluminum-plastic film is packaged first, followed by the bottom side. The top side is packaged after electrolyte injection. The other right or left side, formed by folding aluminum-plastic film, does not require packaging.

[0030] In one embodiment, the workbench 1 includes a vertical rod 18, and the second detection sensor 5 is a human infrared detection sensor, which is mounted on the vertical rod 18. The second detection sensor 5 can also be a laser rangefinder sensor; however, since the laser rangefinder sensor emits a laser beam, and the operator works by hand on the rotating plate 2, it is easy to miss detections.

[0031] As one embodiment, the first bracket 10 is also provided with an LED display screen to show whether the pressing component has pressed the battery core wrapped in aluminum-plastic film onto the placement component 3, or whether the operator has left the turntable 2.

[0032] When the battery core packaging device is in operation, the operator first wraps the battery core with aluminum-plastic film, then places the wrapped battery core onto the placement member 3 located below the first detection sensor 4. The operator then presses down on the pressing plate, moving it away from the first detection sensor 4. The first detection sensor 4 detects that the pressing plate has pressed the wrapped battery core onto the placement member 3. After the second detection sensor 5 detects that the operator has moved away from the rotating plate 2, it controls the rotating plate 2 to rotate, moving the placement member 3 below the first packaging member. The first packaging member operates once after the rotating plate 2 rotates once, packaging the sides of the aluminum-plastic film. After the rotating plate 2 rotates again, the placement member 3, located below the first packaging member, moves below the second packaging member, and the first packaging member operates again, packaging the sides of the aluminum-plastic film on the placement member 3 that has just moved below it. The second packaging component works once after the rotating plate 2 rotates once, sealing the bottom edge of the aluminum-plastic film. After the rotating plate 2 rotates again, the placement component 3 located below the second packaging component moves to below the first cylinder 6, and the second packaging component works again, sealing the bottom edge of the aluminum-plastic film on the placement component 3 that has just moved below it. The first cylinder 6 extends and retracts once after the rotating plate 2 rotates once. During extension, it lifts the pressing plate, allowing the robot or operator to pick up the packaged battery core. After the rotating plate 2 rotates again, the already lifted pressing plate rotates to the signal of the first detection sensor 4. At this time, the first detection sensor 4 detects the pressing plate, and the packaging device stops the rotation of the rotating plate 2 until the pressing block 9 presses onto the placement component 3. Only after the operator leaves the rotating plate 2 will the rotating plate 2 be controlled to rotate again. The rotating plate 2 rotates 90 degrees each time.

[0033] Compared with existing technologies, the advantages of this invention are as follows: The packaging device described in this application detects that the pressing component presses the battery core wrapped in aluminum-plastic film onto the placement component 3 through the first detection sensor 4, and then controls the rotation of the rotating plate 2 only after the second detection sensor 5 detects that the operator has left the rotating plate 2, so that the first packaging component and the second packaging component can package different sides of the aluminum-plastic film, thereby improving the working efficiency of the packaging device; if any detection sensor fails to detect the corresponding signal, the rotating plate 2 will not rotate, which improves the working efficiency of the packaging device and also improves the safety of the operation.
