Description

Technical Field

[0001] This utility model relates to the technical field of lithium battery assembly positioning equipment, specifically a positioning seat for lithium battery assembly. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. When assembling a lithium battery pack, the lithium batteries are installed one by one into the slots of the battery rack.

[0003] To facilitate the assembly of lithium battery packs, existing technologies have made numerous improvements to the positioning bases used for lithium battery assembly. For example, patent publication number CN219759664U discloses a lithium battery assembly auxiliary tool. This tool addresses the problem in existing technologies where workers need to insert each lithium battery into an assembly rack without a positioning aid, making assembly inconvenient. A rotating device is mounted above the base and is fixedly connected to the base with fastening screws. A lifting device is mounted above the rotating device and is rotatably connected to it. A cantilever is mounted on one side of the lifting device and is slidably connected to it. A positioning box is mounted at one end of the cantilever and is fixedly connected to the cantilever with bolts. A positioning hole is provided inside the positioning box, and the positioning hole and the positioning box are an integral structure. A lithium battery is placed inside the positioning box, and the lithium battery can pass through the positioning hole.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4A positioning base for lithium battery assembly includes a support platform 1, on which a frame positioning frame 2 for positioning lithium battery racks is provided. A rotatable rotating plate 3 is also provided on the upper part of the support platform 1. Two symmetrical and vertically oriented vertical support columns 4 are fixedly installed on the upper part of the rotating plate 3. Rotary moving seats 5 are provided on opposite sides of the two vertical support columns 4. A fixed clamping plate 6 and a movable clamping plate 7 are provided on the side of the rotating moving seat 5 away from the vertical support columns 4. An auxiliary positioning plate 8, which is displaceable and adapted to the fixed clamping plate 6 and the movable clamping plate 7, is provided on one side of the fixed clamping plate 6. A first rotary motor 9 for driving the rotating plate 3 to rotate is provided below the support platform 1, and a motor for driving the rotating plate is provided on one side of the support platform 1. The first driving unit 10 for movement is provided on the two vertical support columns 4 facing each other, and the second rotary motor 11 for driving the rotary moving seat 5 to rotate is provided on one end of the rotary moving seat 5, and the second driving unit 12 for driving the moving clamp 7 to move is provided on the upper end of the vertical support column 4, and the third driving unit 13 for driving the rotary moving seat 5 to move up and down is provided on the upper part of the support platform 1. The fixed frame 14 adapted to the position of the frame positioning frame 2 is also fixedly installed on the upper part of the fixed frame 14. The telescopic device 15 with telescopic effect is fixedly installed on the upper part of the fixed frame 14. The lower end of the telescopic device 15 is fixedly installed with a lower pressure plate 16 adapted to the auxiliary positioning plate 8. Several arc-shaped placement slots 34 are opened on the facing sides of the fixed clamp 6 and the moving clamp 7.

[0027] Specifically, when assembling lithium battery packs, the battery racks are secured within the rack positioning frame 2. A second rotary motor 11, located away from the rack positioning frame 2, is activated. This motor drives the rotating moving seat 5 to rotate, causing the fixed clamping plate 6 and the movable clamping plate 7 to tilt. The auxiliary positioning plate 8 is positioned at the lowest side of the fixed clamping plate 6. Several lithium batteries are placed on the fixed clamping plate 6, within the arc-shaped placement slot 34. The second drive unit 12 is then activated to move the movable clamping plate 7 towards the fixed clamping plate 6, clamping and positioning the lithium batteries. Due to the cooperation of the auxiliary positioning plate 8 and the tilted fixed clamping plate 6, the ends of the lithium batteries are flush. The second rotary motor 11 then drives the rotating moving seat 5 to rotate the lithium batteries to a vertical position. In this state, the first rotary motor 9 is started, which drives the rotating plate 3 to rotate, rotating the lithium battery above the rack positioning frame 2. The first drive unit 10 drives the rotating plate 3 to move horizontally, moving the lithium battery to the required assembly position. The third drive unit 13 is started to drive the rotating moving seat 5 to move down, and the lower end of the lithium battery is inserted into the rack mounting hole. During the downward movement of the lithium battery, the lithium battery is placed between another set of fixed clamping plates 6 and moving clamping plates 7. The lithium battery is placed while the assembly is being carried out. Placing the lithium battery is more convenient and faster than inserting the lithium battery, improving the efficiency of lithium battery assembly. At the same time, the telescopic device 15 can be started. The telescopic end of the telescopic device 15 drives the lower pressure plate 16 to move down. The lower pressure plate 16 presses down on the auxiliary positioning plate 8, improving the efficiency of inserting the lithium battery into the rack.

[0029] Specifically, when the first drive motor 17 is turned on, the output end of the first drive motor 17 drives the first drive screw 20 to rotate. When the first drive screw 20 rotates, it drives the first sliding block 18 to slide in the first sliding groove 19. The first sliding block 18 drives the rotating plate 3 to move, so that the rotating plate 3 can be moved. The output end of the first rotating motor 9 passes through the first sliding block 18 and is fixedly installed at the lower part of the rotating plate 3.

The second drive screw 24 passes through the second sliding block 22 and is threadedly connected to it.

[0031] Specifically, the second drive motor 21 is turned on, and the output end of the second drive motor 21 drives the second drive screw 24 to rotate. When the second drive screw 24 rotates, it drives the second sliding block 22 to slide in the second sliding groove 23. The second sliding block 22 drives the moving clamp 7 to move, thereby clamping and fixing the lithium battery.

[0032] As a technical optimization of this utility model, the third drive unit 13 includes a third drive motor 25 fixedly installed on the upper end of the vertical support column 4, a third sliding block 26 rotatably connected to one side of the rotating moving seat 5, a third sliding groove 27 adapted to the third sliding block 26 being opened through the side of the vertical support column 4, a third drive screw 28 with one end fixedly installed to the output end of the third drive motor 25 being rotatably connected in the third sliding groove 27, the third drive screw 28 passing through the third sliding block 26 and being threadedly connected to it, and a second rotary motor 11 fixedly installed on one side of the third sliding block 26 and used to drive the rotating moving seat 5 to rotate.

[0033] Specifically, the third drive motor 25 is turned on, and the output end of the third drive motor 25 drives the third drive screw 28 to rotate. When the third drive screw 28 rotates, it drives the third sliding block 26 to slide in the third sliding groove 27. The third sliding block 26 drives the rotating moving seat 5 to move. The output end of the second rotary motor 11 passes through the third sliding block 26 and is fixedly installed on one side of the rotating moving seat 5.

[0034] As a technical optimization of this utility model, a number of first fixing blocks 29 are fixedly connected to one side of the auxiliary positioning plate 8, and a number of second fixing blocks 30 adapted to the first fixing blocks 29 are fixedly connected to one side of the clamping plate 6.

A limit plate 33 is fixedly connected to one end of the movable column 31 away from the first fixing block 29.

[0035] Specifically, the auxiliary positioning plate 8 facilitates the end alignment of several lithium batteries. When the pressure plate 16 is pressed down, the auxiliary positioning plate 8 moves down accordingly. At this time, the moving column 31 moves down and the spring 32 is compressed. After the lithium battery is assembled, the pressure plate 16 moves up and the tension of the spring 32 pushes the auxiliary positioning plate 8 to reset, which facilitates the automatic reset of the auxiliary positioning plate 8 and further improves the efficiency of lithium battery assembly.
