Technical Field

[0001] The utility model relates to battery module processing equipment, in particular to a battery module positioning mechanism. Background Art

[0002] The end plates and insulating covers of the battery modules need to be positioned during processing to ensure the accuracy of the processing equipment. Common positioning mechanisms mostly use servo mechanisms for positioning, which are costly, cumbersome, and take up a lot of space. Each time the servo mechanism positions a product, it can only execute according to a predetermined program. When the product size tolerance is large and there are two products with different specifications or even different softness and hardness at the same time, the servo mechanism will have various faults such as crushing the product and deforming the parts, which is not conducive to the positioning of the module material by the processing equipment. In view of the above-mentioned existing technologies, it is necessary to provide a positioning mechanism with a simple structure that can achieve compatible positioning of different modules.

DETAILED DESCRIPTION

[0022] Example 1: Figures 1 to 3 The battery module positioning mechanism shown includes a frame 1 and an upper plate 2 tilted relative to the frame 1. The surface of the upper plate 2 serves as the basic positioning plane for materials. The bottom horizontal direction of this positioning plane is defined as the X-axis, and the longitudinal direction is defined as the Y-axis. When materials are placed on the upper plate 2, they slide along the Y-axis. The upper plate 2 is preferably tilted at a 60° angle relative to the frame 1 to facilitate the free sliding of the materials. The purpose of this utility model is to accurately locate the position of materials on the surface of the upper plate 2 and to accommodate materials of different specifications.

[0023] like Figure 4 As shown, it also includes an X-axis positioning assembly and a Y-axis positioning assembly for positioning the material from the X-axis and Y-axis respectively. The Y-axis positioning assembly includes a plurality of positioning blocks 4 arranged along the X-axis direction at the lower end of the surface of the upper plate 2. The positioning blocks 4 protrude from the surface of the upper plate 2, limiting the lower limit position of the material. The material will automatically stay above the positioning blocks 4 along the inclined surface of the upper plate 2. The positioning blocks 4 are arranged at the driving end of the Y-axis driving member 7 and are driven by the Y-axis driving member 7 to move to the target position in the Y-axis direction to achieve precise positioning of the bottom of the material. Furthermore, the end face of the positioning block 4 opposite to the material is installed with a gasket 5 made of flexible material, which can provide flexible support for the bottom of the material and ensure that the support surfaces of each positioning block 4 are coplanar.

[0024] The materials targeted by this embodiment include module end plates and insulation covers of varying specifications. Because release paper on the material surface typically needs to be removed before positioning, leaving the adhesive surface on the back of the material facing the surface of the upper plate 2, an anti-sticking layer is applied to the upper plate 2's positioning surface for the material to prevent excessive friction between the adhesive surface of the material and the supporting surface of the upper plate 2, preventing smooth movement on the surface of the upper plate 2. Furthermore, multiple positioning blocks 4 are connected to a single crossbeam 18, which is connected to the drive end of a Y-axis driver 7. This single Y-axis driver 7 drives the multiple positioning blocks 4 to move synchronously.

[0025] The X-axis positioning assembly includes a side pressure plate 8 arranged on the side of the upper plate 2. The side pressure plate 8 is connected to the driving end of an X-axis driving member 6 and protrudes from the surface of the upper plate 2. The material is pushed along the length direction of the upper plate 2 to a preset position through the drive of the X-axis driving member 6.

[0026] The X-axis drive member 6 and the Y-axis drive member 7 in this embodiment are both cylinders, and the cylinder with a small stroke has the advantage of being stable in place. The cylinder can be fixedly connected to the lower surface of the upper plate 2 by a bracket, or a structure as provided in this embodiment can be adopted, in which a lower plate 3 is provided below the upper plate 2, and the lower plate 3 is connected to the frame 1 through an inclined support plate 17, and the upper plate 2 is connected to the upper part of the lower plate 3 through a column 9, and the above-mentioned cylinders are all fixedly mounted on the surface of the lower plate 3. The side pressure plate 8 and the positioning block 4 extend from the bottom of the upper plate 2, and a avoidance hole 10 is provided on the surface of the upper plate 2 for the positioning component to extend out. The setting of the double-layer plate is conducive to the distribution of each driving component, saves the occupied space of the equipment, and prevents the product from colliding with the driving component during operation.

[0027] Furthermore, the surface of the lower plate 3 is provided with guide rails 11 extending along the X-axis and the Y-axis respectively, and the bottom of the crossbeam 18 and the side pressure plate 8 are slidably connected to the guide rails 11 for guiding the movement of the X-axis positioning assembly and the Y-axis positioning assembly.

[0028] Furthermore, the surface of the lower plate 3 is provided with a photoelectric sensor component 12 for monitoring the initial and final strokes of the X-axis positioning component and the Y-axis positioning component, which is used to accurately determine the travel positions of the positioning block 4 and the side pressure plate 8 to ensure the accuracy of the final positioning.

[0029] This embodiment operates as follows: The robot moves the module end plate and insulation cover onto the surface of the upper plate 2. Due to gravity, the module end plate and insulation cover are automatically blocked by the positioning block 4. The positioning block 4 limits the bottom plane of the material, ensuring that the bottom surfaces of materials of different sizes are on the same support surface. The Y-axis drive 7 pushes the material along the Y-axis. Once in place, the side baffles activate, and the material is driven by the X-axis drive 6 along the X-axis, ultimately reaching the preset positioning position.

[0030] Example 2: Figure 5 and Figure 6 The battery module positioning platform shown is similar in structure to that of Example 1, including both X-axis and Y-axis positioning assemblies. However, this embodiment also includes a Z-axis positioning assembly for positioning the top surface of the material. The Z-axis positioning assembly includes a pressure rod 13 positioned above the upper plate 2 and a rotating shaft 14 rotatably connected to the upper plate 2 via bearings. The ends of the pressure rod 13 are connected to the ends of the rotating shaft 14 via connecting rods 15. Driven by the rotary drive structure, the rotating shaft 14 in turn rotates the pressure rod 13, pressing it against the material surface.

[0031] In this embodiment, a connecting rod structure is used to drive the rotation of the rotating shaft 14. The connecting rod 15 is a lever structure. The driving end of the connecting rod 15 is connected to the driving end of a push-pull cylinder 16, which is rotatably connected to the lower plate 3. The fulcrum of the connecting rod 15 is rotatably connected to both ends of the rotating shaft 14, and the driven end of the connecting rod 15 is connected to the pressure rod 13. Through this connecting rod mechanism, the linear travel of the push-pull cylinder 16 is converted into the rotational travel of the pressure rod 13. Furthermore, the upper plate 2 is equipped with a photoelectric sensor on the side of the pressure rod 13 to monitor the initial and final travel of the pressure rod 13 and determine whether the pressure rod 13 is in place.

[0032] The Z-axis positioning assembly of this embodiment cooperates with the X-axis positioning assembly and the Y-axis positioning assembly to fix the position of the material, so that the material can be kept stable during the flow process even if the frame 1 is in a moving state.

[0033] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
