Description

Technical Field

[0001] Embodiments of this disclosure relate to the field of clamping and strapping machine technology, and more specifically, to a clamping and strapping machine for square lithium batteries. Background Technology

[0002] Square lithium batteries consist of a steel / aluminum casing, a top cover integrating safety devices and electrodes, positive and negative electrode plates containing materials such as lithium iron phosphate / lithium cobalt oxide, a separator that isolates the positive and negative electrodes to prevent short circuits and allows lithium ions to pass through, insulating components, and safety components such as NSD needle penetration safety devices. During charging, lithium ions are deintercalated from the positive electrode and move to the negative electrode through the separator. During discharging, they move in the opposite direction to release energy. They are characterized by compact structure and high safety.

[0003] When assembling square lithium batteries, multiple square lithium batteries need to be squeezed together using a clamping and strapping machine. After the multiple square lithium batteries are squeezed together, the operator needs to manually put straps on the multiple square lithium batteries to tie them. However, after the multiple square lithium batteries are placed on the clamping and strapping machine and pressed tightly, since the bottom surface of the square lithium batteries is completely in contact with the placement platform, it is difficult for the straps to pass through the bottom of the multiple square lithium batteries when tying them, thus reducing the efficiency and effectiveness of tying multiple square lithium batteries. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a clamping and strapping machine for square lithium batteries, which solves the technical problem in the prior art that, because the bottom surface of the square lithium battery is in complete contact with the placement platform, the strapping strap is difficult to pass through the bottom of multiple square lithium batteries when strapping, thereby reducing the efficiency and effectiveness of strapping multiple square lithium batteries.

[0005] According to one aspect, at least one embodiment of this disclosure provides a clamping and strapping machine for square lithium batteries, including a frame, a placement platform disposed within the frame, and further including: a limiting plate, a pressing plate, and a lifting mechanism. The limiting plate is disposed at the bottom end of the placement platform via a telescopic mechanism. Two pressing plates are provided, both of which are disposed within the frame via a pressing mechanism, enabling the pressing of multiple square lithium batteries. The lifting mechanism is disposed within the frame and is capable of driving the placement platform to adjust its height.

[0006] In order to drive the limiting plate to retract to the bottom of the placement platform and make the surface of the placement platform flat, the telescopic mechanism includes: a base plate, a fixed frame and a first electric cylinder. The base plate is fixedly connected to the bottom of the limiting plate. A sliding groove is opened on the placement platform, and the limiting plate is slidably connected in the sliding groove. The fixed frame is fixed to the bottom of the placement platform. The first electric cylinder is installed at the bottom of the fixed frame, and the output end of the first electric cylinder passes through the fixed frame and is fixedly connected to the base plate.

[0007] In order to extrude multiple square lithium batteries, the extrusion mechanism includes: a drive rod and a second electric cylinder. The drive rod is fixedly connected to both extrusion plates. There are two second electric cylinders, both of which are mounted on the frame. The output ends of the two second electric cylinders pass through the frame and are fixedly connected to the two drive rods respectively.

[0008] To drive the placement platform to descend, the lifting mechanism includes: a moving block, a support rod, and a driving assembly. There are two moving blocks, which are slidably disposed within the frame via a sliding assembly. Both ends of the two moving blocks are rotatably connected to support rods, and the top ends of multiple support rods are rotatably connected to the placement platform. The driving assembly is disposed within the frame and is capable of driving the two moving blocks to move relative to each other.

[0009] To increase the stability of the moving blocks during movement, the sliding assembly includes two sliding rods, both of which are fixedly connected to the frame. Each of the two moving blocks has a sliding hole, and the sliding rod is slidably connected to the sliding hole.

[0010] To drive the two moving blocks to move relative to each other, the drive assembly includes a bidirectional screw and a first motor. The bidirectional screw is rotatably connected inside the frame. Each of the two moving blocks has a screw hole. The two threads of the bidirectional screw are respectively threaded into the two screw holes. The first motor is installed on one side of the frame. The output end of the first motor passes through the frame and is fixedly connected to one end of the bidirectional screw.

[0011] To increase the stability of the support rods when they rotate, the bottom of the placement platform is fixedly connected to multiple rotating seats, and the top ends of the multiple support rods are respectively rotatably connected to the multiple rotating seats.

[0012] To increase the stability between the support rod and the moving block, a rotating shaft is fixedly connected to the moving block, and a rotating hole is opened at the bottom end of the support rod, with the rotating shaft rotatably connected in the rotating hole.

[0013] The beneficial effects of the embodiments disclosed herein are as follows:

[0014] In this disclosure, the compression mechanism facilitates the compression of multiple square lithium batteries. The lifting and telescopic mechanisms drive the limiting plate to descend on the placement platform and the entire placement platform to descend, thereby freeing up space at the bottom of the clamped square lithium batteries. This makes it easier for operators to bundle and strap the multiple square lithium batteries, improving the efficiency and effectiveness of bundling them. Attached Figure Description

[0021] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0027] like Figures 1-4 The diagram illustrates a clamping and strapping machine for square lithium batteries according to an embodiment of this disclosure. It includes a frame 1, a placement platform 2 within the frame 1, and further comprises a limiting plate 3, a pressing plate 4, and a lifting mechanism. The limiting plate 3 is positioned at the bottom of the placement platform 2 via a telescopic mechanism. Two pressing plates 4 are provided, each positioned within the frame 1 via a pressing mechanism, capable of pressing multiple square lithium batteries. The lifting mechanism, located within the frame 1, drives the placement platform 2 to adjust its height. The pressing mechanism facilitates the pressing of multiple square lithium batteries. The lifting and telescopic mechanisms allow the limiting plate 3 to descend on the placement platform 2, and also lower the entire placement platform 2, thus creating space at the bottom of the clamped square lithium batteries. This facilitates the operator's strapping of the multiple square lithium batteries, improving the efficiency and effectiveness of strapping.

[0028] The telescopic mechanism includes a base plate 5, a fixing frame 6, and a first electric cylinder 7. The base plate 5 is fixedly connected to the bottom end of the limiting plate 3. A sliding groove is provided on the placement platform 2, and the limiting plate 3 is slidably connected in the sliding groove. The fixing frame 6 is fixed to the bottom end of the placement platform 2. The first electric cylinder 7 is installed at the bottom end of the fixing frame 6. The output end of the first electric cylinder 7 passes through the fixing frame 6 and is fixedly connected to the base plate 5. The first electric cylinder 7 drives the base plate 5 and the limiting plate 3 to descend, thereby driving the limiting plate 3 to descend in the sliding groove provided on the placement platform 2, thereby lowering the limiting plate 3 to the bottom of the placement platform 2, thereby clearing space on one side of the multiple square lithium batteries.

[0029] The extrusion mechanism includes a drive rod 8 and a second electric cylinder 9. The drive rod 8 is fixedly connected to both extrusion plates 4. There are two second electric cylinders 9, and both second electric cylinders 9 are mounted on the frame 1. The output ends of the two second electric cylinders 9 pass through the frame 1 and are fixedly connected to the two drive rods 8 respectively. The second electric cylinders 9 drive the drive rods 8 to move, thereby driving the extrusion plates 4 to clamp multiple square lithium batteries between the two extrusion plates 4 for extrusion.

[0030] The lifting mechanism includes: a movable block 10, a support rod 11, and a drive assembly. A rotating shaft 16 is fixedly connected to the movable block 10. A rotating hole is formed at the bottom end of the support rod 11, and the rotating shaft 16 is rotatably connected within the rotating hole. Multiple rotating seats 15 are fixedly connected to the bottom end of the placement platform 2. The top ends of the multiple support rods 11 are rotatably connected within the multiple rotating seats 15. Two movable blocks 10 are provided, and the two movable blocks 10 are slidably disposed within the frame 1 via a sliding assembly. Support rods 11 are rotatably connected to both ends of each of the two movable blocks 10, and the top ends of the multiple support rods 11 are rotatably connected to the placement platform 2. The drive assembly is disposed within the frame 1 and can drive the two movable blocks 10 to move relative to each other. The sliding assembly includes: two slide rods 12, both of which are fixedly connected within the frame 1. Both movable blocks 10 have sliding holes, and the sliding rod 12 is slidably connected in the sliding holes. The driving assembly includes a bidirectional screw 13 and a first motor 14. The bidirectional screw 13 is rotatably connected in the frame 1. Both movable blocks 10 have screw holes, and the two threads of the bidirectional screw 13 are respectively threaded into the two screw holes. The first motor 14 is installed on one side of the frame 1. The output end of the first motor 14 passes through the frame 1 and is fixedly connected to one end of the bidirectional screw 13. The first motor 14 drives the bidirectional screw 13 to rotate. When the bidirectional screw 13 rotates, it drives the two movable blocks 10 to move in opposite directions, thereby driving the support rods 11 on both sides to move synchronously with the movable blocks 10, thereby driving the placement plate to descend, thereby releasing space at the bottom of the multiple square lithium batteries that have been squeezed, thus making it easier for the operator to bundle the square lithium batteries.

[0031] The working principle is as follows: When multiple square lithium batteries need to be assembled and bundled, the multiple square lithium batteries are placed on the placement platform 2. Then, the limiting plate 3 is used to align the multiple square lithium batteries neatly. Then, the second electric cylinder 9 drives the drive rod 8 to move, thereby driving the extrusion plate 4 to clamp the multiple square lithium batteries between the two extrusion plates 4 for compression. After compression, the two extrusion plates 4 remain stationary. The first electric cylinder 7 drives the bottom plate 5 and the limiting plate 3 to descend, thereby driving the limiting plate 3 to descend within the sliding groove opened on the placement platform 2, thereby lowering the limiting plate 3 to the bottom of the placement platform 2, thus making room on one side of the multiple square lithium batteries. The first motor 14 drives the bidirectional screw 13 to rotate. When the bidirectional screw 13 rotates, it drives the two moving blocks 10 to move in opposite directions, thereby driving the support rods 11 on both sides to move synchronously with the moving blocks 10, thereby driving the placement plate to descend, thus freeing up space at the bottom of the multiple square lithium batteries that have been compressed, making it convenient for the operator to pass the straps through the bottom of the square lithium batteries and bundle them.
