[0002] Polishing equipment for automotive sensor production is a precision device used to polish the surfaces of automotive sensor housings, sensitive elements, or connecting components. It uses a high-speed rotating polishing wheel to contact the sensor surface, applying pressure and polishing paste to achieve minute material removal and surface smoothing. By using this polishing equipment, surface quality can be improved, stress concentration reduced, and the mechanical strength and corrosion resistance of the sensor enhanced. Furthermore, electrical performance can be optimized. For sensors requiring conductive contact, polishing can reduce contact resistance and improve signal transmission stability.
[0003] Chinese Patent Publication No. CN212240497U relates to the field of sensor technology and discloses a surface polishing device for sensor housings. The device includes a mounting frame with fixed feet at its bottom and a placement groove at its top.

Rotating rods are rotatably connected to both the left and right side walls of the mounting frame, and fixed frames are fixedly mounted on the opposite faces of the two rotating rods. A sliding block is slidably connected inside the fixed frame, and a first spring is fixedly connected between the sliding block and the fixed frame. This surface polishing device for sensor housings, by setting a sliding frame, allows the user to fix the sensor housing using the sliding block, thereby reducing the pressure of the polishing device on the sensor housing and facilitating user operation.
[0004] In practical use, this utility model typically relies on grinding wheels to process the sensor surface. However, existing polishing equipment for automotive sensor production usually requires multiple polishing processes to achieve precise control of sensor surface quality. This process often requires operators to frequently disassemble and replace grinding wheels of different grit sizes to adapt to the process requirements from coarse grinding to fine grinding, which consumes a lot of time and manpower, thus making the polishing equipment for automotive sensor production somewhat inconvenient to use.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Example 1:
[0028] Please see Figure 1-4 This utility model provides a polishing equipment for automotive sensor production, comprising:
[0029] Workbench 1 and positioning frame 2;
[0030] Mounting plate 3 is set inside positioning frame 2, which is set on the upper end of workbench 1. Mounting plate 3 is rotatably connected to mounting disc 4 on one side.
[0031] Multiple grinding wheel bodies 5 are respectively set on the outside of the mounting plate 4. The mesh size of the multiple grinding wheel bodies 5 is arranged in an increasing manner. The multiple grinding wheel bodies 5 are evenly distributed in a ring around the central axis of the mounting plate 4.
[0032] The processing frame 6 is set on the upper end of the workbench 1. The processing frame 6 is equipped with a screening plate 7. The upper ends of the screening plate 7 are equipped with fixing plates 8 on both sides. Two clamping plates 9 are provided between the two fixing plates 8.
[0033] Specifically, such as Figure 2 As shown, the mounting plate 4 has multiple drive slots, and each drive slot is equipped with a drive motor 10. The drive motor 10 is existing technology and will not be described in detail here. The output ends of the multiple drive motors 10 extend to the outside and are respectively set on one side of the multiple grinding wheel bodies 5. When the multiple drive motors 10 are started, they will drive the multiple grinding wheel bodies 5 to rotate, thereby polishing the automotive sensor.
[0034] Specifically, such as Figure 2 and Figure 3 As shown, the mounting plate 3 is provided with a locking rod 11, and the mounting disc 4 is provided with a plurality of locking holes 12 that are adapted to the locking rod 11. The locking rod 11 passes through one side of the locking hole 12 and is slidably connected to the side wall of the locking hole 12.
[0035] Through its design, the movable locking rod 11, in conjunction with multiple locking holes 12 on the mounting plate 4, allows the mounting plate 4 to rotate when the locking rod 11 disengages from the locking hole 12, thereby adjusting the grinding wheel bodies 5 of different grit sizes. When the locking rod 11 is located in different locking holes 12, the mounting plate 4 can be fixed at different angles, thus effectively limiting the position of multiple grinding wheel bodies 5.
[0036] Specifically, such as Figure 2As shown, a fixing ring 13 is provided on one side of the locking rod 11, and a return spring 14 is sleeved on the outside of the locking rod 11. The two ends of the return spring 14 are respectively set on the mounting plate 3 and the fixing ring 13. The fixing ring 13 and the return spring 14 can ensure that the locking rod 11 is always located in the locking hole 12, thereby ensuring the stability of the polishing equipment used in the production of automotive sensors.
[0037] Specifically, such as Figure 1 As shown, a cylinder 15 is provided at the upper end of the positioning frame 2. The cylinder 15 is existing technology and will not be described in detail here. The output end of the cylinder 15 passes through the positioning frame 2 and is located at the upper end of the mounting plate 3. When the cylinder 15 is started, it can drive the mounting plate 3 and the mounting disk 4 to move up and down, thereby driving the grinding wheel body 5 to move and polish the automotive sensor. The upper end of the mounting plate 3 is provided with multiple guide rods 16. The upper ends of the multiple guide rods 16 all pass through the upper end of the positioning frame 2 and extend to the outside. The multiple guide rods 16 can limit the up and down movement of the mounting plate 3 and the mounting disk 4 to prevent their position from shifting, thereby ensuring the accuracy of the polishing operation of the automotive sensor.
[0038] Specifically, such as Figure 4 As shown, each of the two fixed plates 8 is rotatably connected to a mounting shaft 17 on one side. Each of the two mounting shafts 17 is equipped with an electric push rod 18 at one end. The electric push rod 18 is existing technology and will not be described in detail here. The output ends of the two electric push rods 18 are respectively located on one side of the two clamping plates 9. The two electric push rods 18 can drive the two clamping plates 9 to move respectively, thereby fixing the car sensor in different positions, so that the grinding wheel body 5 can flexibly polish different positions of the car sensor.
[0039] Specifically, such as Figure 4 As shown, a servo motor 19 is provided on one side of the fixed plate 8. The servo motor 19 is existing technology and will not be described in detail here. One end of the mounting shaft 17 on one side passes through the fixed plate 8 and is set on the output end of the servo motor 19. When the servo motor 19 is started, it will drive the mounting shaft 17 on one side to rotate, thereby driving the two clamping plates 9 and the car sensor to rotate, which can conveniently polish different surfaces of the car sensor.
[0040] Example 2:
[0041] Please see Figure 1-4 This utility model provides a polishing equipment for automotive sensor production, comprising:
[0042] Workbench 1 and positioning frame 2;
[0043] Mounting plate 3 is set inside positioning frame 2, which is set on the upper end of workbench 1. Mounting plate 3 is rotatably connected to mounting disc 4 on one side.
[0044] Multiple grinding wheel bodies 5 are respectively set on the outside of the mounting plate 4. The mesh size of the multiple grinding wheel bodies 5 is arranged in an increasing manner. The multiple grinding wheel bodies 5 are evenly distributed in a ring around the central axis of the mounting plate 4.
[0045] The processing frame 6 is set on the upper end of the workbench 1. The processing frame 6 is equipped with a screening plate 7. The upper ends of the screening plate 7 are equipped with fixing plates 8 on both sides. Two clamping plates 9 are provided between the two fixing plates 8.
[0046] Specifically, such as Figure 2 As shown, the bottom of the mounting plate 3 is provided with an inclined air extraction pipe 20. One end of the air extraction pipe 20 is connected to an air supply pipe 21, and the other end of the air supply pipe 21 is connected to a main air pipe 22. One end of the main air pipe 22 is connected to one side of the bottom of the processing frame 6, and the other end of the main air pipe 22 is provided with a filter box 23. The other side of the filter box 23 is provided with an air pump 24. The air pump 24 is existing technology and will not be described in detail here.
[0047] Its design allows for the extraction of air through the air pump 24, which in turn draws air from the extraction pipe 20, the air supply pipe 21, and the main air pipe 22. This effectively collects the waste generated during the polishing of automotive sensors. The filter box 23 filters and collects the waste, effectively preventing the waste from polluting the working environment.
[0048] See Figure 1-4 When polishing automotive sensors using polishing equipment, firstly, two electric push rods 18 need to be activated. The output ends of the two electric push rods 18 will drive the two clamping plates 9 to move, thus clamping and fixing the position of the automotive sensor. Next, cylinder 15 is activated, which will drive the mounting plate 3 and mounting disk 4 to move downwards. Then, the drive motor 10 located at the bottom is activated, and its output end can drive the grinding wheel body 5 located at the bottom to rotate, thereby polishing the automotive sensor. During the polishing process, the air pump 24 is activated, which can make the suction pipe 20, air supply pipe 21 and main air supply pipe open. The pipe 22 is used for air extraction, which can effectively collect the waste generated by polishing into the filter box 23, thereby avoiding its impact on the working environment. When it is necessary to change the grinding wheel body 5 with a different grit, the locking rod 11 needs to be moved, and then the mounting plate 4 needs to be rotated to adjust the position of the grinding wheel body 5. After rotation, the locking rod 11 is moved into the corresponding locking hole 12, which can limit the position of the mounting plate 4 and the grinding wheel body 5, thereby facilitating the replacement of the grinding wheel body 5. This avoids the cumbersome bolt disassembly and installation steps in the traditional grinding wheel disassembly and assembly process, greatly saving time and labor costs.
