Description

Technical Field

[0001] This utility model relates to the field of water-cooled plate preparation technology, and in particular to a brazing-type water-cooled plate grinding device. Background Technology

[0002] Brazing is a process that uses liquid filler metal to wet the base material, fill the gaps at the interface, and diffuse with the base material to connect the welded parts. Brazed water-cooled plates are heat dissipation devices that connect flow channel plates and cover plates into a whole through brazing. They are widely used in high-power heat dissipation scenarios such as new energy vehicles, energy storage systems, and 5G base stations.

[0003] During the processing of water-cooled plates, a weld is formed at the brazing joint between the flow channel plate and the cover plate. The weld needs to be manually ground to remove the residual oxide layer and welding slag, and ground until it is flush with the surface of the substrate to ensure compatibility with subsequent assembly or spraying processes. Manual grinding is inefficient and the grinding quality is not guaranteed. Utility Model Content

[0004] The purpose of this utility model is to provide a brazed water-cooled plate grinding device to solve the problems of low efficiency and poor grinding quality in the existing post-weld grinding process of water-cooled plates.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a brazing-type water-cooled plate grinding device, comprising: The carrier module includes a base, a platform, and a Y-axis drive unit. The platform is slidably connected to the base and has several positioning pins. The water-cooled plate is placed on the platform, and the positioning pins contact the side wall of the water-cooled plate. The height of the positioning pins is less than the thickness of the water-cooled plate. The Y-axis drive unit is fixedly installed on the base and is used to drive the platform to move in a straight line. The grinding module includes an X-axis mover, a sliding seat, a Z-axis mover, a lifting seat, a rotary motor, a mounting plate, and a grinding head. The sliding seat is fixedly mounted on the first moving platform of the X-axis mover, the Z-axis mover is fixedly mounted on the sliding seat, the lifting seat is fixedly mounted on the second moving platform of the Z-axis mover, the rotary motor is fixedly mounted on the lifting seat, the mounting plate is fixedly mounted on the motor shaft of the rotary motor, and the grinding head is fixedly mounted on the mounting plate with the grinding disc of the grinding head facing the water-cooled plate.

[0006] As a further description of the above technical solution: The edge of the platform has a notch, the movable plate is set in the notch, and the movable plate has symmetrically arranged protrusions on both sides. The protrusions are slidably connected in the grooves on the side wall of the notch.

[0007] As a further description of the above technical solution: A spring is installed inside the notch, with one end of the spring fixedly installed on the inner wall of the notch and the other end fixedly installed on the movable plate.

[0008] As a further description of the above technical solution: A vision camera is installed on one side of the grinding head. The vision camera is fixedly mounted on the mounting plate. The mounting plate is rotated by a rotary motor so that the vision camera is located behind the grinding head in the grinding direction.

[0009] As a further description of the above technical solution: A distance sensor is also installed on one side of the grinding head. The distance sensor is fixedly mounted on the mounting plate and faces the water-cooling plate.

[0010] As a further description of the above technical solution: The Y-axis drive unit is an electric linear actuator, which is fixedly mounted on the base platform. The piston rod of the electric linear actuator is connected to the platform.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, after the water-cooled plate is placed on the platform, its horizontal position is fixed by the positioning pin. The grinding disc of the grinding head in the grinding module is lowered to contact the water-cooled plate by the Z-axis mover. The X-axis movement of the grinding head is coordinated with the Y-axis movement of the platform to grind the weld seam on the upper surface of the water-cooled plate, which effectively improves the grinding efficiency. At the same time, the X-axis movement and Y-axis movement are decomposed to simplify the movement path of the grinding head and improve the grinding quality.

[0012] 2. In this utility model, the edge of the platform is provided with a notch, and the movable plate is disposed in the notch. During the grinding process of the water-cooled plate, the movable plate is located below the edge of the water-cooled plate to support the water-cooled plate; when the water-cooled plate is ground and transported for unloading, the movable plate is pushed to move away from the notch opening, so that a person can reach under the water-cooled plate to facilitate the unloading of the water-cooled plate.

Detailed Implementation

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] Please see Figure 1-4 This utility model provides a technical solution: a brazing-type water-cooled plate grinding device, comprising: The support module 1 includes a base 11, a platform 12, and a Y-axis drive unit 13. The platform 12 is slidably connected to the base 11. Several positioning pins 121 are provided on the platform 12. The water-cooled plate 9 is placed on the platform 12. The positioning pins 121 contact the side wall of the water-cooled plate 9. The height of the positioning pins 121 is less than the thickness of the water-cooled plate 9. The Y-axis drive unit 13 is fixedly installed on the base 11. The Y-axis drive unit 13 is used to drive the platform 12 to move in a straight line. Grinding module 2 includes an X-axis mover 21, a sliding seat 22, a Z-axis mover 23, a lifting seat, a rotary motor 24, a mounting plate 25, and a grinding head 26. The sliding seat 22 is fixedly mounted on the first moving platform of the X-axis mover 21, the Z-axis mover 23 is fixedly mounted on the sliding seat 22, the lifting seat is fixedly mounted on the second moving platform of the Z-axis mover 23, the rotary motor 24 is fixedly mounted on the lifting seat, the mounting plate 25 is fixedly mounted on the motor shaft of the rotary motor 24, and the grinding head 26 is fixedly mounted on the mounting plate 25. The grinding disc 261 of the grinding head 26 faces the water-cooled plate 9.

[0021] The Y-axis drive unit 13 is an electric push rod, which is fixedly mounted on the base 11. The piston rod of the electric push rod is connected to the platform 12.

[0022] The electric linear actuator can precisely control the moving distance and speed of the stage 12, ensuring grinding quality. Meanwhile, the Y-axis drive unit 13, hidden beneath the stage 12, effectively reduces the impact of grinding dust, improving reliability.

[0023] Working principle: After the water-cooled plate 9 is placed on the stage 12, its horizontal position is fixed by the positioning pin 121. The grinding disc 261 of the grinding head 26 in the grinding module 2 descends to contact the water-cooled plate 9 through the Z-axis mover 23. The X-axis movement of the grinding head 26 is coordinated with the Y-axis movement of the stage 12 to grind the weld seam on the upper surface of the water-cooled plate 9, effectively improving grinding efficiency. At the same time, the X-axis movement and Y-axis movement are decomposed to simplify the movement path of the grinding head 26 and improve the grinding quality. Example 2

[0024] This embodiment further improves upon the above embodiment by providing the following technical solution: A notch 122 is provided on the edge of the platform 12, and a movable plate 123 is disposed within the notch 122. Symmetrically arranged protrusions are provided on both sides of the movable plate 123, and the protrusions are slidably connected to grooves on the sidewall of the notch 122. During the grinding process of the water-cooled plate 9, the movable plate 123 is located below the edge of the water-cooled plate 9, supporting the water-cooled plate 9. When the water-cooled plate 9 is ground and unloaded, the movable plate 123 is pushed away from the opening of the notch 122, allowing a hand to reach under the water-cooled plate 9 for easy unloading. Example 3

[0025] Based on the above embodiments, this embodiment further improves upon the following technical solution: a spring 124 is provided inside the notch 122, with one end of the spring 124 fixedly installed on the inner wall of the notch 122 and the other end fixedly installed on the movable plate 123.

[0026] Spring 124 enables the movable plate 123 to be elastically connected, and it can automatically reset after being released from the push, effectively ensuring that the movable plate 123 is located below the edge of the water-cooled plate 9, thus ensuring the support effect.

[0027] To further limit the travel of the movable plate 123 and prevent it from disengaging from the notch 122, a stop block can be provided at the end opening of the notch 122 to prevent the movable plate 123 from popping outward. Example 4

[0028] Based on the above embodiments, this embodiment further improves upon the following technical solution: a vision camera 27 is provided on one side of the grinding head 26. The vision camera 27 is fixedly mounted on the mounting plate 25. The mounting plate 25 is rotated by the rotary motor 24, so that the vision camera 27 is located behind the grinding head 26 in the grinding direction.

[0029] See appendix Figure 3 When the grinding head 26 moves along the X-axis via the X-axis mover 21 to complete the grinding of the weld seam on one side of the water-cooled plate 9, the rotary motor 24 drives the mounting plate 25 to rotate 90 degrees. Then, the stage 12 drives the water-cooled plate 9 to move along the Y-axis, so that the vision camera 27 is still located behind the grinding head 26 in the grinding direction, effectively using the vision camera 27 to collect the weld seam image after grinding, so as to evaluate the grinding quality. Example 5

[0030] Based on the above embodiments, the following improved technical solutions are further made in this embodiment: a distance sensor 28 is also provided on one side of the grinding head 26. The distance sensor 28 is fixedly installed on the mounting plate 25 and faces the water cooling plate 9.

[0031] The distance sensor 28 is used to monitor the distance between the mounting plate 25 and the water-cooled plate 9, thereby controlling the downward height of the grinding head 26 and ensuring the grinding quality of the weld.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
