Description

Technical Field

[0001] The utility model relates to the technical field of glass substrate processing, in particular to a glass substrate surface treatment device. Background Art

[0002] A glass substrate is an extremely flat thin glass sheet and is one of the key basic materials in the flat panel display industry. It has excellent mechanical, physical and optical properties and is widely used in the fields of electronics, optics, etc. Especially, it has extremely high flatness, which is crucial for manufacturing high-quality liquid crystal display devices. Its ultra-flat surface allows for more precise etching, thereby increasing the circuit density per unit area and further improving the performance and quality of liquid crystal display devices. During the production of glass substrates, in order to ensure the display effect of the glass substrates, a surface treatment device is needed to grind the surface of the glass substrates to make the surface of the glass substrates flat and smooth.

[0003] However, in the existing technology, during the grinding process of glass substrates, when the grinding process of one side of the glass substrate is completed, usually, the operator needs to manually release the fixation of the glass substrate first, and then flip the glass substrate to perform the grinding process on the other side. The grinding efficiency of the front and back sides of the glass substrate is relatively low, time-consuming and laborious, and the operation steps are relatively cumbersome. Moreover, when grinding smaller or irregularly shaped glass substrates, the clamping and fixing effect of the glass substrates is poor, and the glass substrates are prone to loosen during the grinding process, which will affect the grinding quality and flatness of the glass substrates. Summary of the Utility Model

[0008] One end of the shaft rod away from the first motor is provided with a clamping assembly. The clamping assembly includes a U-shaped frame and an elastic buffer. One end of two arc-shaped sliding blocks is connected to the U-shaped frame. A pneumatic push rod is arranged on the U-shaped frame, and the output end of the pneumatic push rod is connected to the elastic buffer.

One end of the fixed rod is matched with the through hole. A spring is fitted on the outer surface of the fixed rod. One end of the spring contacts with one side surface of the movable plate. Arc-shaped clamping plates are arranged at one ends of the two fixed rods away from the movable plate, and arc-shaped limiting grooves are formed in the arc-shaped clamping plates.

[0010] Preferably, a vertical plate is installed on the workbench, and a driving member is arranged on the vertical plate. The driving member is an XY two-axis cross slide.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Refer to Figures 1-4 , a glass substrate surface treatment device, including a workbench 1, a vertical plate 5 is vertically installed on the workbench 1, a driving member 6 is arranged on the vertical plate 5, the driving member 6 is an XY two-axis cross slide, a electro-hydraulic push rod 7 is arranged on the sliding part of the driving member 6, a second motor 8 is arranged at the output end of the electro-hydraulic push rod 7, a grinding disk 801 is installed at the output end of the second motor 8, a rectangular through groove is opened on the workbench 1, a collection box 9 is fitted in the rectangular through groove, and can collect the debris generated by grinding and the cleaning liquid waste generated by cleaning. The collection box 9 is located directly below the driving member 6, and two fixing brackets 2 are installed on the workbench 1, and arc-shaped placement grooves 201 are opened on the fixing brackets 2.

[0025] An overturning assembly 3 is installed on the arc-shaped placement groove 201. The overturning assembly 3 includes a fixed disk 301 and a first motor 302. A through groove is formed in the fixed disk 301. A shaft rod 303 is rotatably fitted in the through groove. One end of the shaft rod 303 passes through the through groove. The first motor 302 is installed on the fixed disk 301. The output end of the fixed disk 301 is connected to one end of the shaft rod 303. An annular groove 3011 is formed in the fixed disk 301. Two arc-shaped sliding blocks 304 are fitted in the annular groove 3011, which can enable the clamping assembly 4 to rotate stably.

[0026] One end of the shaft rod 303 away from the first motor 302 is provided with a clamping assembly 4. The clamping assembly 4 includes a U-shaped frame 401 and an elastic buffer 403. One end of each of the two arc-shaped sliding blocks 304 is connected to the U-shaped frame 401. A pneumatic push rod 402 is arranged on the U-shaped frame 401. The output end of the pneumatic push rod 402 is connected to the elastic buffer 403. A connecting buckle is arranged at the output end of the pneumatic push rod 402, and the connecting buckle is matched with the U-shaped frame 401.

[0027] The elastic buffer 403 includes a movable plate 4031 and a fixed rod 4032. Two sliders 4034 are arranged on the movable plate 4031. Two chutes 4011 are formed in the U-shaped frame 401. The sliders 4034 are matched with the chutes 4011, which can enable the movable plate 4031 to displace smoothly on the U-shaped frame 401. Two through holes 4035 are formed in the movable plate 4031. There are two fixed rods 4032. One end of each fixed rod 4032 is matched with the through hole 4035. A limit disk is arranged at one end of the fixed rod 4032 to prevent the movable plate 4031 from sliding out of the surface of the fixed rod 4032. A spring 4033 is fitted on the outer surface of the fixed rod 4032. The spring 4033 can prevent damage to the glass substrate caused by excessive clamping force. One end of the spring 4033 contacts one side surface of the movable plate 4031. Arc-shaped clamping plates 404 are arranged at one ends of the two fixed rods 4032 away from the movable plate 4031. Arc-shaped limit grooves 4041 are formed in the arc-shaped clamping plates 404 to limit the position of the glass substrate and prevent displacement during grinding.

[0028] When the glass substrate needs to be ground, the glass substrate is horizontally placed between two arc-shaped clamping plates 404, and then a pair of pneumatic push rods 402 are started synchronously. The output end of the pneumatic push rod 402 pushes the elastic buffer 403 to move on the U-shaped frame 401. Through the cooperation of the slider 4034 and the chute 4011, the movable plate 4031 horizontally slides on the U-shaped frame 401, so that the two arc-shaped clamping plates 404 approach each other. When the two arc-shaped clamping plates 404 contact the two sides of the glass substrate through the arc-shaped limiting grooves 4041 thereon and produce extrusion, at this time, the movable plate 4031 horizontally slides on the surfaces of the two fixed rods 4032 through the two through holes 4035 thereon. One side of the movable plate 4031 contacts and is extruded by the two springs 4033. The thrust of the pneumatic push rod 402 and the acting force transmitted by the elastic buffer 403 cause the spring 4033 to contract. Through the resilience generated by the contraction of the spring 4033, the glass substrate can be stably fixed between the pair of arc-shaped clamping plates 404, avoiding damage to the glass substrate caused by excessive clamping force. After the glass substrate is fixed, under the cooperation of the driving member 6, the electric hydraulic push rod 7 and the second motor 8, a series of grinding processes are performed on the glass substrate fixed between the pair of arc-shaped clamping plates 404 through the grinding disc 801, so that the smaller or irregularly shaped glass substrate can be stably clamped and fixed, avoiding loosening of the glass substrate during the grinding process, effectively reducing the grinding error of the glass substrate, and improving the grinding quality and flatness of the glass substrate.

[0029] When one side of the glass substrate is ground and the other side of the glass substrate needs to be ground, at this time, first clean the ground side of the glass substrate, and then start two first motors 302 synchronously. The output end of the first motor 302 drives the shaft rod 303 to rotate at the center of the fixed disk 301. Through the rotation of the shaft rod 303, the clamping assembly 4 installed at one end of the shaft rod 303 rotates. While the clamping assembly 4 rotates, the two arc-shaped sliding blocks 304 connected to the U-shaped frame 401 slide in the annular groove 3011 on the flipping assembly 3, improving the rotational stability of the clamping assembly 4, so that the glass substrate fixed between the pair of clamping assemblies 4 rotates. When the glass substrate is flipped 180 degrees, stop the two first motors 302, so that the two sides of the glass substrate can be efficiently ground, effectively shortening the operation time, increasing the grinding speed of the glass substrate, and greatly improving the grinding efficiency of the device.

[0030] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
