Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a self-locking cell tray and cell conveying line. Background Technology

[0002] To meet the growing demand for battery packs, energy storage battery pack manufacturers are now demanding higher efficiency and greater adaptability in their battery production equipment, requiring the equipment to achieve the lowest cost, fastest speed, and greatest adaptability during the production process.

[0003] Currently, the manufacturing process of energy storage battery packs requires multiple pre-processing steps for the battery cells. However, the pre-processing stations are relatively scattered and independent. The cells are manually transported or transported via stepper lines using trays. However, most trays do not have a cell locking function, which makes the cells prone to shaking during transport. Some trays do have a cell locking function, but unlocking is cumbersome and inconvenient. Furthermore, the current independent and scattered pre-processing stations result in discontinuous and slow cell processing, making it difficult to meet the ever-increasing production capacity requirements. In addition, the labor and equipment costs are extremely high. Moreover, the stepper line method of transporting cells is characterized by short stepper lines and slow speed. Utility Model Content

[0004] Based on this, in view of the technical problems that the current trays do not have a locking function, and the independent and decentralized pre-processing stations lead to discontinuous and slow battery cell processing, making it difficult to adapt to the increasing production capacity requirements, this utility model needs to provide a self-locking battery cell tray and battery cell conveying line.

The sliding direction of the two side clamps is perpendicular to the sliding direction of the movable plate. The two side clamps are movably connected to the movable plate through connectors. The two ends of the elastic element are respectively connected to the two side clamps. When the elastic element is in its natural state, the two side clamps together clamp the battery cells on the support plate.

After releasing the pressure, the two side clamps move back to their original position and clamp the battery cell under the action of the elastic element, preventing the battery cell from shaking during transport. When unlocking the battery cell, only a certain amount of pressure needs to be applied to the moving plate to release the battery cell from the two side clamps, which is convenient.

[0026] To facilitate understanding of this invention, a more comprehensive description of the invention will be provided below with reference to specific embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] This embodiment addresses the technical problems in the current pre-processing of energy storage battery pack cells, such as slow stepping line speed, poor continuity of processing steps, low automation of cell pre-processing, and high difficulty in production changeover. It provides a cell conveyor line that, together with a self-locking cell tray and a hinged track line, enables rapid and continuous processing of multiple pre-processing steps for energy storage battery pack cells. This improves the automation level of energy storage battery pack cell pre-processing, reduces the difficulty and cost of production changeover, increases production efficiency, saves costs, facilitates production changeover, and can meet the ever-increasing production demand.

[0029] Reference Figure 1 This embodiment proposes a battery cell conveying line, which includes a mounting frame 18 and a tray guide rail 19, a power hinge 20, multiple positioning mechanisms, multiple unlocking mechanisms, and multiple self-locking battery cell trays mounted on the mounting frame 18. The multiple self-locking battery cell trays are slidably mounted on the tray guide rail 19 and move along the tray guide rail 19 under the drive of the power hinge 20. Multiple unlocking and positioning stations are sequentially arranged on the mounting frame 18 along the conveying direction of the tray guide rail 19. Multiple positioning mechanisms and multiple unlocking mechanisms are respectively installed at the multiple unlocking and positioning stations to position and unlock the self-locking battery cell trays. The mounting frame 18 can be mounted on a workbench. A support plate 31 is provided on the mounting frame 18. Considering the numerous battery cell pretreatment processes and the long length of the guide rail, the power hinge 20 is placed inside the support plate 31 to support the hinge.

[0030] In this embodiment, the self-locking cell tray includes a base plate 1, a support plate 2, a movable plate 3, two side clamps 4, and an elastic element 1, and may also include two guide rods 12.

[0031] To enable the self-locking cell tray to move on the tray guide rail 19, combined with Figure 2 , Figure 3 A positioning block 21 is installed at the bottom of the substrate 1. Multiple guide wheels 22 are located on both sides of the tray guide rail 19 and slide in cooperation with the tray guide rail 19. A power input plate 23 is provided on the positioning block 21, and the power input plate 23 is connected to a power hinge 20. Thus, driven by the power hinge 20, the substrate 1 can move along the tray guide rail 19.

[0032] Four rectangular uprights 8 are provided on the substrate 1, and the four corners of the tray 2 are connected to the four uprights 8 by screws. In this embodiment, the tray 2 is used to place square aluminum-cased battery cells. It has a rectangular structure and is made of marble. The battery cells are placed on the tray 2 without directly contacting the metal parts, which can protect the battery cells.

[0033] The movable plate 3 is located below the support plate 2. A linear guide rail 16 is mounted on the base plate 1, and the bottom of the movable plate 3 is mounted on the slider of the linear guide rail 16, allowing the movable plate 3 to move relative to the base plate 1. Figure 4 The movable plate 3 has two waist-shaped grooves 11 arranged in a V-shape. A T-shaped plate 32 is connected to one end of the movable plate 3 in its moving direction. The vertical section of the T-shaped plate 32 is connected to the movable plate 3, and a clamping screw 15 is provided on the side of the horizontal section of the T-shaped plate 32 away from the vertical section. Two guide rods 12 are provided on both sides of the vertical section of the T-shaped plate 32. One end of the guide rod 12 is connected to a mounting block 13, and the mounting block 13 is fixed to the base plate 1. One end of the guide rod 12 slides through the horizontal section of the T-shaped plate 32 and is connected to a stop block. A compression spring 14 is fitted on the guide rod 12 between the mounting block 13 and the horizontal section of the T-shaped plate 32. The two ends of the compression spring 14 are connected to the mounting block 13 and the movable plate 3, respectively.

[0034] Two side clamps 4 are disposed on both sides of the support plate 2 in the width direction. The two side clamps 4 are used to clamp the battery cells on the support plate 2. To avoid damaging the battery cells, polyurethane contour pads 7 are provided on the side of each side clamp 4 that is close to each other. The two side clamps 4 are movably connected to the moving plate 3 through connectors. In this embodiment, the connectors include pins 9 and mounting plates 10. The two pins 9 are slidably disposed in the two waist-shaped grooves 11. Linear guide rails 17 perpendicular to linear guide rail 16 are disposed on both sides of linear guide rail 16 on the base plate 1. The two mounting plates 10 are respectively connected to the sliders of the two linear guide rails 17, that is, the moving direction of the two mounting plates 10 is perpendicular to the sliding direction of the moving plate 3. One end of the two mounting plates 10 is connected to the two pins 9, and the two side clamps 4 are respectively connected to the two mounting plates 10.

[0035] The elastic element is connected to two side clamping plates 4 at both ends. In this embodiment, the elastic element includes a tension spring 5, and each of the two side clamping plates 4 is provided with a pull rod 6 on one side close to each other. The tension spring 5 is connected to the two pull rods 6 at both ends. Under the action of the two compression springs, the clamping force of the two side clamping plates 4 on the battery cell can be increased, preventing the battery cell from shaking due to the movement of the pallet during transportation.

[0036] With the above structural configuration, when the tension spring 5 is in its natural state, the two side clamps 4 can jointly clamp the battery cell on the support plate 2. When pressure is applied to the clamping screw 15 to drive the moving plate 3 to move through the T-shaped plate 32, the movement of the moving plate 3 will cause the two pins 9 to slide in the two waist-shaped grooves respectively, thereby driving the two mounting plates 10 to move away from each other. The two mounting plates 10 will drive the two side clamps 4 to move away from each other, and the T-shaped plate 32 will compress the two compression springs 14. When the pressure is removed, the tension spring 5 will return to its original position and pull the two side clamps 4 closer to each other. The compression spring 14 will also return to its original position and drive the moving plate 3 to its original position. The moving plate 3 will then drive the two side clamps 4 to their original positions through the two mounting plates 10.

[0037] The positioning mechanism includes a positioning cylinder 25 and a positioning guide block 26. The positioning cylinder 25 is mounted on the mounting bracket 18, and the positioning guide block 26 is connected to the telescopic end of the positioning cylinder 25. The telescopic movement of the positioning cylinder 25 drives the positioning guide block 26 to rise and fall. A positioning groove 24 is provided on the edge of the positioning block 21 above the positioning guide block 26. The structure of the positioning guide block 26 is adapted to the positioning groove 24. During the rising process, the positioning guide block 26 can extend into the positioning groove 24 to restrict the movement of the substrate 1, thereby achieving the positioning of the self-locking battery cell tray.

[0038] The unlocking mechanism includes a support base 27, an unlocking cylinder 28, and an unlocking screw 29. The support base 27 can be directly mounted on the workbench. The unlocking cylinder 28 is mounted on the support base 27. The telescopic end of the unlocking cylinder 28 is equipped with a mounting base 30, and the unlocking screw 29 is mounted on the mounting base 30. The telescopic movement of the unlocking cylinder 28 causes the unlocking screw 29 to move horizontally. Figure 5 When the positioning mechanism positions and fixes the self-locking cell tray, the unlocking screw 29 is set coaxially opposite to the clamping screw 15. The unlocking cylinder 28 extends, and the unlocking screw 29 moves horizontally to apply pressure to the clamping screw 15, thereby driving the moving plate 3 to move.

[0039] With the battery cell conveying line structure set in this embodiment, positioning and unlocking stations can be set sequentially along the conveying direction of the battery cell conveying line. The battery cells are put on the battery cell conveying line and conveyed to each positioning and unlocking station in sequence. The battery cells can be pre-processed at each positioning and unlocking station. When the battery cells are put on the line, the positioning mechanism can be set at the line-on station to position the tray and the unlocking mechanism can be set to unlock the tray so that the two side clamps 4 are far apart. The battery cells are loaded onto the tray 2 manually or by machine. Then the unlocking cylinder 28 retracts, the two side clamps 4 clamp the battery cells, the positioning cylinder 25 retracts, and the tray is conveyed forward with the battery cells under the drive of the power hinge 20. When the tray is conveyed to the next positioning and unlocking station, the positioning cylinder 25 extends, the positioning guide block 26 is inserted into the positioning groove 24 to position the entire tray. At the same time, the unlocking cylinder 28 of the unlocking mechanism is selected to move or remain still according to the processing situation of the station. After the pre-processing is completed, the battery cells are clamped and conveyed forward. This embodiment realizes rapid and continuous processing of multiple pre-processing steps for energy storage battery pack cells, improves the automation level of energy storage battery pack cell pre-processing, reduces the difficulty and cost of production changeover, improves production efficiency, saves costs, facilitates production changeover, and can meet the ever-increasing production demand.

[0040] Considering the long length of the guide rail and the error in the power hinge 20, the error increases when the equipment operates for a long time. The unlocking screw 29 of the unlocking mechanism may be misaligned with the clamping screw 15 and fail to unlock the tray. Therefore, the tray positioning mechanism must be set up. At the same time, during equipment debugging, the positioning mechanism can be used to check whether the self-locking cell tray has moved into place.

[0041] It should be noted that the self-locking battery cell tray provided in this embodiment can also use other conveyor lines, such as synchronous toothed belt conveyors, to replace the power hinge, and use the synchronous toothed belt conveyor to drive the tray to move along the tray guide rail.

[0042] It should be noted that when a component is said to be "installed on" another component, it can be directly on the other component or it may be in a component that is centered on it. When a component is said to be "set on" another component, it can be directly set on the other component or it may also be in a component that is centered on it. When a component is said to be "fixed to" another component, it can be directly fixed to the other component or it may also be in a component that is centered on it.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
