Description

Technical Field

[0001] This utility model relates to the field of vacuum cavity grinding technology, and in particular to a port grinding device for vacuum cavity processing. Background Technology

[0002] A vacuum chamber is a structure developed to reduce the number of vacuum chambers in semiconductor applications. Therefore, it is generally equipped with a moving vacuum with a pre-installed air bearing and a differential vacuum groove. As a result, during the manufacturing process, the ends of the formed workpiece need to be polished to ensure that they are in a smooth state.

[0003] Existing vacuum chambers have multiple ports, which need to be polished during processing. Traditional polishing devices often require workers to use sandpaper to polish the ports of vacuum chambers, which is inefficient, produces poor polishing results, and can lead to dust inhalation, seriously affecting the operator's health. Safety cannot be guaranteed when polishing the ports of vacuum chambers. Therefore, a port polishing device for vacuum chamber processing is proposed. Utility Model Content

[0004] The technical problem this invention aims to solve is that the use of sandpaper for polishing is inefficient, produces poor polishing results, and causes dust to be inhaled during the polishing process, seriously affecting the operator's health. Furthermore, safety cannot be guaranteed when polishing the port of a vacuum chamber.

[0005] To solve the above-mentioned technical problems, the present invention provides a port grinding device for vacuum cavity processing, comprising a base plate, a vertical plate fixedly connected to the top of the base plate, a driving assembly provided on one side of the vertical plate, two clamping blocks provided on the side of the vertical plate away from the driving assembly, each of the two clamping blocks having an inclined groove on its opposite side, a transmission assembly provided on the side of the vertical plate near the driving assembly, a fixing plate fixedly connected to the top of the base plate, a lead screw rotatably connected between the fixing plate and the vertical plate, a driving block being threadedly connected to the outside of the lead screw, a fixing block fixedly connected to the top of the driving block, a rotating shaft rotatably connected to one side of the fixing block, a connecting plate fixedly connected to one end of the rotating shaft, and an electric guide rail fixedly installed on one side of the connecting plate;

The dust hood is located outside the grinding machine. An annular tube is fixedly connected inside the dust hood. Multiple dust suction ports are opened on one side of the annular tube. A conduit is fixedly connected to the side of the annular tube away from the dust suction ports, and one end of the conduit extends through to the outside of the dust hood. A dust collection box is fixedly connected to one side of the fixing block. A fan is fixedly connected to one side of the dust collection box. One end of the conduit is installed through into the inside of the dust collection box.

[0007] Preferably, the driving assembly includes two limiting plates, which are fixedly connected to one side of the vertical plate. A bidirectional screw is rotatably connected between the two limiting plates. A driving frame is threadedly connected to the outside of the bidirectional screw. One end of each driving frame is fixedly connected to one side of a corresponding clamping block. The driving frame can be moved relative to the other side by the bidirectional screw, thereby adjusting the position of the clamping block and facilitating clamping when grinding the port of the vacuum chamber.

[0008] Preferably, the transmission assembly includes a first servo motor, which is fixedly connected to one side of the vertical plate. A main gear is fixedly connected to the output end of the first servo motor. A driven gear is fixedly connected to the outside of the bidirectional screw.

After the first servo motor stops, a self-locking effect can be achieved to ensure stability between the main gear and the driven gear.

[0009] Preferably, two transverse grooves are symmetrically formed on the top of the base plate, and a slider is embedded in each of the two transverse grooves. One side of each slider is fixedly connected to both sides of the drive block. By allowing the sliders to slide inside the transverse grooves, the drive block can be limited while ensuring greater stability when the drive block moves.

[0010] Preferably, a motor is fixedly connected to one side of the surface of the fixed plate, and the output end of the motor extends through to one side of the fixed plate and is fixedly connected to one end of the lead screw. The motor can drive the lead screw on one side of the fixed plate.

[0011] Preferably, a second servo motor is fixedly connected to one side of the fixed block, and the output end of the second servo motor passes through the fixed block and is fixedly connected to one end of the rotating shaft. The rotating shaft can be driven by the second servo motor.

The rotating shaft 26 facilitates the rotation of the connecting plate 11. An electric guide rail 25 is fixedly installed on one side of the connecting plate 11.

[0023] The drive end of the electric guide rail 25 is fixedly connected to the grinder 24, which facilitates the movement of the grinder 24. A dust cover 10 is fixedly connected to one side of the connecting plate 11. The dust cover 10 is located outside the grinder 24. An annular tube 9 is fixedly connected inside the dust cover 10. Multiple suction ports 13 are opened on one side of the annular tube 9. A conduit 12 is fixedly connected to the side of the annular tube 9 away from the suction ports 13, and one end of the conduit 12 extends through to the outside of the dust cover 10. A dust collection box 22 is fixedly connected to one side of the fixing block 17. A fan 21 is fixedly connected to one side of the dust collection box 22. One end of the conduit 12 is installed through to the inside of the dust collection box 22, which can adsorb and collect the dust generated during the grinding process.

[0024] like Figure 1 , Figure 2 as well as Figure 4 As shown, two horizontal slots 19 are symmetrically opened on the top of the base plate 2. A slider 27 is slidably connected inside each horizontal slot 19. One side of the two sliders 27 is fixedly connected to both sides of the drive block 28.

After the first servo motor 4 stops, a self-locking effect is achieved to ensure stability between the main gear 3 and the driven gear 18.

[0026] In use, the vacuum chamber to be processed is placed between two clamping blocks 8. The first servo motor 4 is turned on, driving the main gear 3 to rotate. The rotation of the main gear 3 drives the driven gear 18 to rotate, which in turn drives the bidirectional screw 5 to rotate. The rotation of the bidirectional screw 5 moves the drive frame 6, which in turn moves the two clamping blocks 8. Simultaneously, the inclined groove 20 clamps and fixes the vacuum chamber to maintain relative stability. At the same time, the motor 14 is turned on, driving the lead screw 16 to rotate. The rotation of the lead screw 16 moves the drive block 28, which in turn moves the vacuum chamber. The moving fixed block 17 is moved so that the dust removal hood 10 is placed outside the vacuum chamber. The second servo motor 23 is turned on, and the second servo motor 23 drives the rotating shaft 26 to rotate. The rotating shaft 26 can drive the connecting plate 11 to rotate, and the grinding machine 24 can be moved to a suitable position by the action of the electric guide rail 25. Grinding can be performed on the ports at different positions. Dust will be generated during the grinding process. The fan 21 is turned on, and the dust collection box 22 and the duct 12 create a negative pressure inside the dust collection box 22. The dust is adsorbed by the cooperation of the annular pipe 9 and the suction port 13. When the work is stopped, the collection box on one side of the dust collection box 22 can be opened for centralized cleaning, which is very convenient.
