Description

Technical Field

[0001] This utility model relates to the field of pressure regulation technology for double-shot blasting machines, specifically to a top pressure regulation mechanism and a double-shot blasting machine. Background Technology

[0002] A glass double-sided polishing machine, also known as a glass double-sided polishing machine, is a device that can polish both the upper and lower surfaces of a glass material simultaneously. It is widely used for high-precision double-sided polishing of hard and brittle materials such as optical glass, semiconductor silicon wafers, sapphire, and ceramic sheets. It can handle workpieces with thicknesses ranging from tens of micrometers to hundreds of millimeters, with processing accuracy reaching the micrometer to sub-micrometer level.

[0003] In the prior art, in order to avoid damage to the glass during the polishing process, a pressure regulating mechanism is required to adjust the pressure applied by the top polishing disc. However, the existing double polishing machine top pressure regulating mechanism only uses a single pressure sensor located at the vertical center position for monitoring and adjustment during use. During long-term use, the pressure distribution of the top polishing disc will be uneven due to angular deviation. The pressure monitoring of the top polishing disc by a single pressure sensor is not accurate, which can easily damage the surface of the glass. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a top pressure adjustment mechanism and a double polishing machine, which solves the problem that the existing double polishing machine top pressure adjustment mechanism, which only uses a single pressure sensor located at the vertical center position for monitoring and adjustment, does not accurately monitor the pressure of the top polishing disc during use.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a top pressure adjustment mechanism, including a mounting plate, an electric telescopic rod vertically fixedly connected to the upper surface of the mounting plate, the bottom end of the electric telescopic rod extending movably to the bottom of the mounting plate and fixedly connected to a protective shell, and a receiving seat rotatably provided inside the protective shell; The bottom of the receiving seat is movably provided with a lifting seat, and the bottom of the lifting seat is provided with a top polishing mechanism. The interior of the receiving seat has several monitoring chambers, which are arranged in a circular array along the interior of the receiving seat. Several vertical rods are fixedly connected to the upper surface of the lifting seat. The top of the vertical rods is pulled out and extended into the interior of the corresponding monitoring chamber, and a lifting block is fixedly connected thereto. A pressure sensor is fixedly connected to the top of the inner wall of the monitoring chamber, and a spring is vertically arranged between the pressure sensor and the lifting block.

[0006] Furthermore, a support frame is fixedly connected inside the protective shell, and a support plate is fixedly connected to the bottom of the support frame. The receiving seat is rotatably disposed inside the support plate.

[0007] Furthermore, a shielding shell is fixedly connected to the side wall of the protective shell, and a motor is detachably installed inside the shielding shell via a connecting seat. A rotating rod is fixedly connected to the top of the receiving seat, and a second pulley is fixedly connected to the surface of the rotating rod. A first pulley is fixedly connected to the output shaft of the motor, and the first pulley and the second pulley are connected by a transmission belt.

[0008] Furthermore, the top polishing mechanism includes a connecting shaft, a flow divider, and a polishing disc. The connecting shaft is vertically fixed to the bottom of the lifting seat, the flow divider is fixedly connected to the bottom of the connecting shaft, and the polishing disc is fixedly connected to the bottom of the flow divider.

[0009] Furthermore, the lower surface of the polishing disc is provided with a plurality of liquid spraying nozzles, the surface of the distribution disc is connected to a plurality of distribution pipes, the plurality of distribution pipes correspond one-to-one with the plurality of liquid spraying nozzles, and the other end is connected to the interior of the corresponding liquid spraying nozzle. The surface of the protective shell is provided with a liquid injection component connected to the distribution disc.

[0010] A double polishing machine includes a double polishing machine frame, the aforementioned top pressure adjustment mechanism, and a lower polishing disc assembly. The top pressure adjustment mechanism is disposed at the top of the inner cavity of the double polishing machine frame, and the lower polishing disc assembly is disposed inside the double polishing machine frame and located below the top pressure adjustment mechanism.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: multiple pressure sensors are evenly distributed in a ring along the inside of the receiving seat. When the electric telescopic rod extends, it can drive the top polishing mechanism to descend to contact the glass surface through the connection between the receiving seat and the lifting seat. After the top polishing mechanism is subjected to force, it can drive the lifting seat, vertical rod and lifting block to move. The compression spring contracts and deforms to generate elastic force. After the elastic force acts on the pressure sensors, the pressure can be monitored. By monitoring whether the pressure values ​​of multiple pressure sensors are consistent, it can be determined whether the top polishing mechanism is perpendicular to the surface of the glass workpiece. This avoids uneven pressure distribution caused by angular deviation, which can damage the glass during the polishing process. This improves the stability of the glass polishing process and thus improves the quality of the finished glass product. Attached Figure Description

A pressure sensor 18 is fixedly connected to the top of the inner wall of the monitoring chamber 16. A spring 19 is vertically arranged between the pressure sensor 18 and the lifting block 17.

[0017] Multiple pressure sensors 18 are evenly spaced and arranged in a ring inside the housing 14. When the electric telescopic rod 2 is extended, it can drive the top polishing mechanism to descend to contact the surface of the glass through the connection between the housing 14 and the lifting seat 15. After the top polishing mechanism is subjected to force, it can drive the lifting seat 15, the vertical rod 9 and the lifting block 17 to move, and compress the spring 19 to contract and deform to generate elastic force.

[0018] After the elastic force is applied to the pressure sensor 18, the pressure can be monitored. By monitoring whether the pressure values ​​of multiple pressure sensors 18 are consistent, it can be determined whether the top polishing mechanism is perpendicular to the surface of the glass workpiece. This avoids uneven pressure distribution caused by angular deviation, which could damage the glass during the polishing process. This improves the stability of the glass polishing process and thus improves the quality of the finished glass product.

[0024] Please see Figure 7 A double polishing machine includes a double polishing machine frame 26, the aforementioned top pressure adjustment mechanism, and a lower polishing disc assembly 27. The top pressure adjustment mechanism is located at the top of the inner cavity of the double polishing machine frame 26, and the lower polishing disc assembly 27 is located inside the double polishing machine frame 26 and below the top pressure adjustment mechanism.

[0025] During operation, multiple pressure sensors 18 are evenly spaced and arranged in a ring inside the housing 14. When the electric telescopic rod 2 extends, it can drive the top polishing mechanism to descend to contact the glass surface through the connection between the housing 14 and the lifting seat 15. After the top polishing mechanism is subjected to force, it can drive the lifting seat 15, the vertical rod 9 and the lifting block 17 to move. The compression spring 19 contracts and deforms to generate elastic force. After the elastic force acts on the pressure sensor 18, the pressure can be monitored. By monitoring whether the pressure values ​​of multiple pressure sensors 18 are consistent, it can be determined whether the top polishing mechanism is perpendicular to the surface of the glass workpiece, so as to avoid uneven pressure distribution due to angular deviation and damage to the glass during the polishing process.
