Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, specifically to a plastic support positioning mechanism. Background Technology

[0002] In battery production, batteries are typically placed in plastic trays for positioning, transport, and assembly. Current processes often use robotic arms or jigs to sequentially load batteries into the plastic trays. However, these processes generally lack effective positioning aids, relying primarily on manual alignment or simple mechanical guide structures (such as bosses and grooves). Manual operation is susceptible to fatigue and visual errors, making it difficult to guarantee consistent positioning. Furthermore, mechanical guides, lacking pre-tightening and buffering structures, are prone to rigid collisions during insertion, causing relative component misalignment. This can lead to problems such as battery jamming or scratches on the casing when sliding into the plastic tray, ultimately resulting in a high product defect rate. Therefore, we propose a plastic tray positioning mechanism. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] In view of the shortcomings of the prior art, this utility model provides a plastic support positioning mechanism to solve the above-mentioned problems existing in the prior art.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a plastic tray positioning mechanism, including a battery plastic tray and a battery guide plate that can move up and down, wherein a plurality of positioning grooves are provided on the bottom wall of the battery plastic tray;

[0007] The battery guide plate is positioned above the battery plastic tray. Several through slots corresponding to the positioning slots are opened inside the plate. The through slots pass through the upper and lower sides of the battery guide plate. Flexible pins are slidably connected inside the through slots along the up and down direction. A compression spring connected to the flexible pins is provided inside the through slots to apply a pre-tightening force to the flexible pins.

[0008] The top of the battery guide plate is equipped with several pop-up sensors corresponding to the slot. These sensors are used to detect the flexible pins that are pushed up by the battery plastic support due to misalignment with the positioning slot when the battery guide plate moves downward, thereby identifying the misalignment state between the battery guide plate and the battery plastic support.

[0009] Furthermore, it also includes a pair of columns, with guide rails arranged vertically on the two columns. A slider is slidably connected to the outer wall of the guide rails. A cylinder is provided on the column, and the output end of the cylinder is connected to the bottom of the slider. A support arm is provided on one side of the slider. The support arms on the two columns are connected to the battery guide plate together.

[0010] Furthermore, the battery support has a groove-shaped structure with an open top, and several mounting slots for accommodating batteries are neatly arranged on its bottom wall, with the positioning slot located outside the mounting slot.

[0011] The battery guide plate has several guide grooves inside its body that correspond one-to-one with the mounting grooves.

[0012] Furthermore, the diameter of the bottom of the guide groove is larger than the diameter of the top of the mounting groove, and both the guide groove and the mounting groove have a structure that is wider at the top and narrower at the bottom.

[0013] Furthermore, the guide rail has a dovetail-shaped cross-section, and the inner wall of the slider is provided with a dovetail groove that is adapted to the dovetail-shaped structure.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See attached document Figure 1-5 A battery tray positioning mechanism includes a battery tray 1 and a vertically movable battery guide plate 2. The bottom wall of the battery tray 1 is provided with several positioning grooves 12. The battery guide plate 2 is positioned above the battery tray 1, and its interior is provided with several through grooves 22 that correspond one-to-one with the positioning grooves 12. The through grooves 22 penetrate the upper and lower sides of the battery guide plate 2, and flexible pins 23 are slidably connected in the vertical direction inside the through grooves 22. A compression spring 24 connected to the flexible pins 23 is provided in the through grooves 22 to apply a preload force to the flexible pins 23. Several pop-up sensors 25 are provided on the top of the battery guide plate 2 at the position corresponding to the through grooves 22. These sensors are used to detect the flexible pins 23 that are popped up by the battery tray 1 due to misalignment with the positioning grooves 12 when the battery guide plate 2 moves downward, thereby identifying the misalignment state between the battery guide plate 2 and the battery tray 1. The pop-up sensors 25 are prior art, and their specific principles will not be elaborated in this application.

[0026] During operation, the battery plastic tray 1 is conveyed to the bottom of the battery guide plate 2 on the production line conveyor mechanism. Then, the battery guide plate 2 moves downward under the drive mechanism, and the flexible pin 23 is inserted into the positioning groove 12 of the battery plastic tray 1. If the battery guide plate 2 and the battery plastic tray 1 are aligned, the flexible pin 23 can be smoothly inserted into the positioning groove 12. If they are not aligned, the flexible pin 23 is pushed up by the bottom wall of the battery plastic tray 1, moves upward and triggers the pop-up sensor 25. The system identifies the missing state through the sensing signal, and thus adjusts or alarms in time.

[0027] In this embodiment, a pair of columns 3 are also included. Guide rails 4 are arranged on the two columns 3 along the vertical direction. A slider 5 is slidably connected to the outer wall of the guide rail 4. A cylinder 6 is provided on the column 3. The output end of the cylinder 6 is connected to the bottom of the slider 5. A support arm 7 is provided on one side of the slider 5. The support arms 7 on the two columns 3 are connected to the battery guide plate 2. The slider 5 is driven to move up and down along the guide rail 4 by the cylinder 6, thereby driving the battery guide plate 2 to move up and down precisely, realizing automated operation.

[0028] In this embodiment, the battery plastic tray 1 has a groove-shaped structure with an open top. Several mounting grooves 11 for accommodating batteries are neatly arranged on its bottom wall, and the positioning groove 12 is located outside the mounting groove 11. Several guide grooves 21 corresponding to the mounting grooves 11 are opened inside the battery guide plate 2. The diameter of the bottom of the guide groove 21 is larger than the diameter of the top of the mounting groove 11. Both the guide groove 21 and the mounting groove 11 have a structure that is wider at the top and narrower at the bottom, which makes it easy for the battery to slide smoothly from the guide groove 21 into the mounting groove 11, achieve rapid and accurate positioning, and reduce jamming.

[0029] In this embodiment, the guide rail 4 has a dovetail-shaped cross-section, and the inner wall of the slider 5 is provided with a dovetail groove that matches the dovetail-shaped structure, ensuring that the slider 5 slides smoothly on the guide rail 4 and preventing the battery guide plate 2 from shaking during movement, thus improving the stability and positioning accuracy of the entire mechanism.
