Description

Technical Field

[0001] The present invention relates to the technical field of display screen processing equipment, and in particular to a high-precision polishing device for a 3D display screen. Background Art

[0002] 3D display technology is an important branch of the display technology field. It aims to realize the display of stereoscopic images through various methods to provide users with a more realistic and immersive viewing experience. Large-screen 3D display screens are usually composed of multiple display panels. When the display panels are produced, polishing equipment is required to polish the upper and lower surfaces of the panels.

[0003] When using a polishing device to polish the surface of a display screen, the display screen needs to be placed on a table of the polishing device, and positioning components for fixing the display screen are installed at different positions on the table according to the size of the display screen. When the display screen is removed, the positioning components are removed. Fixing the display screen in this way is rather cumbersome, resulting in low efficiency when polishing multiple displays in a single batch. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that a display screen needs to be placed on a table plate of a polishing device, and positioning components for fixing the display screen are installed at different positions on the table plate according to the size of the display screen. The positioning components are then removed when the display screen is removed. The operation of fixing the display screen in this way is rather cumbersome, resulting in low efficiency when polishing multiple display screens in a single batch. A high-precision polishing device for 3D display screens is proposed to solve the problem.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a high-precision polishing device for a 3D display screen, comprising a base, a frame body is fixedly connected to the top of the base, a tray and a shaft rod are rotatably arranged on the top of the base, a polishing rod is fixedly connected to one side of the top of the shaft rod, a positioning device is arranged on the outer surface of the tray, the positioning device comprises two positioning rods, a slider is fixedly connected to the bottom end of the positioning rod, two slide grooves are provided on the top of the tray, the outer surfaces of the two sliders slide on the inner walls of the two slide grooves respectively, one end of the slider is fixedly connected to a round rod, the outer surface of the round rod slides on the inner wall of the tray, A first spring is provided on one side of the slider, and two ends of the first spring are respectively fixedly connected to one side of the slider and one side of the inner wall of the slide groove, and groove blocks are respectively fixedly connected to two sides of the tray, and the outer surface of the round rod slides on the inner wall of the groove block, and a rectangular groove is provided inside the groove block, and a metal sheet is fixedly connected to one side of the inner wall of the rectangular groove, and a cylinder is fixedly connected to one end of the groove block, and piston oil is provided inside the cylinder, and a piston rod is slidably connected to the inner wall of the cylinder, and support rods are respectively fixedly connected to two sides of the tray, and an electric push rod is provided on one side of the support rod, and the output rod of the electric push rod is fixedly connected to one end of the piston rod.

[0006] The effect achieved by the above components is as follows: by setting the positioning rods, when polishing the display screen, the display screen panel is placed on the outer surface of the tray, so that the two ends of the display screen panel are in contact with one side of the two positioning rods at the top of the tray, and the two positioning rods are pushed to move away from each other, and at the same time, the sliders at the bottom ends of the two positioning rods will slide on the inner wall of the slide groove and compress the first spring, and the round rod will slide on the inner wall of the tray and the groove block until the display screen panel is placed on the surface of the tray, and the two positioning rods are pushed by the thrust of the first spring so that one side of the two positioning rods is attached to the two sides of the display screen panel, and then the electric push rods on the outer surfaces of the support rods on both sides of the tray are respectively extended, so that the output rod of the electric push rod pushes the piston rod inside the cylinder toward the groove block. The cylinder moves in the direction of the rotation, pushing the piston oil inside the cylinder into the rectangular groove and applying pressure to one side of the metal sheet, so that the outer side of the metal sheet expands and presses against the outer surface of the round rod, fixing the position of the round rod in the groove block and the position of the slider in the slide groove, fixing the position of the positioning rod on the surface of the tray, and fixing the position of the display panel on the outer surface of the tray through the positioning rod. Then, the driving device inside the base controls the rotation of the tray and the shaft rod drives the polishing rod to swing back and forth, and polishes the surface of the display panel through the polishing rod. After the processing is completed, the two electric push rods are operated to contract and the hydraulic oil inside the rectangular groove is extracted to restore the metal sheet to its original state and release the position fixation of the round rod, and then the display can be taken out.

[0007] Preferably, the inner diameter of the round rod is slightly smaller than the diameter of the first spring, and the first spring is located outside the round rod.

[0008] The effect achieved by the above components is that when the slider moves to cause the first spring to deform, the first spring will move outside the round rod. The internal shape of the first spring can be reinforced by the round rod, thereby avoiding surface misalignment at different positions of the first spring when it is compressed, which would affect the normal use of the first spring.

[0009] Preferably, one end of the cylinder is fixedly connected with a sealing ring, and the sealing ring is made of rubber material.

[0010] The effect achieved by the above components is that the outer side of the contact point between the inner wall of the cylinder and the outer surface of the piston rod can be further sealed by arranging a sealing ring made of rubber material, thereby avoiding leakage of piston oil inside the cylinder as much as possible.

[0011] Preferably, a plurality of convex strips are fixedly connected to the outer surface of the round rod, the convex strips are distributed in a circle on the outer surface of the round rod, and the convex strips are made of rubber material.

[0012] The effect achieved by the above components is: by setting the rubber convex strips, when the round rod is located inside the slot block, the metal sheet on one side of the inner wall of the slot block expands and contacts the rubber convex strips on the outer surface of the round rod, the fit is tighter and less likely to slide, making the position of the round rod inside the slot block more stably fixed.

[0013] Preferably, a positioning block is fixedly connected to the top end of the sliding block, and the bottom end of the positioning block slides on the outer surface of the tray.

[0014] The effect achieved by the above components is: when the slider slides on the inner wall of the slide groove, the bottom end of the top positioning block will slide on the outer surface of the tray. The positioning block can further limit the angle between the slider and the tray, thereby avoiding shaking of the slider and the positioning rod when moving as much as possible.

[0015] Preferably, a convenient device is provided on the outer surface of the tray, and the convenient device includes a rectangular rod, and two round blocks are fixedly connected to the bottom end of the rectangular rod, and a card slot is provided on the outer surface of the tray, and two round grooves are provided at the bottom end of the inner wall of the card slot, and the outer surfaces of the two round blocks slide on the inner walls of the two round grooves respectively, and two push grooves are provided inside the tray, and an L-shaped rod is fixedly connected to one side of the output rod of the electric push rod, and an inclined block is fixedly connected to one end of the L-shaped rod, a second spring is provided on one side of the support rod, and a block is provided at one end of the second spring, and the two ends of the second spring are respectively fixedly connected to one side of the block and one side of the support rod, and one end of the block is fixedly connected to an extrusion rod, and the outer surface of the extrusion rod slides on the inner wall of the push groove.

[0016] The effect achieved by the above components is: when the display screen panel is placed on the outer surface of the tray, the display screen will be above the rectangular rod. After the display screen is fixed on the outer surface of the tray by the positioning device, when the display screen is taken out, the electric push rod contracts to move the piston rod. After the piston oil is extracted from the inside of the rectangular groove, the output rod of the electric push rod can continue to move a certain distance, and the output rod of the electric push rod drives the L-shaped rod and the inclined block to move in the direction of the stop block, so that the inclined block moves on one side of the stop block and pushes the stop block to make the extrusion rod slide on the inner wall of the push groove and compress the second spring. The sliding of the extrusion rod on the inner wall of the push groove will generate pressure on the bottom end of the round block inside the circular groove, pushing the round block to slide upward on the inner wall of the circular groove, and the display screen is lifted to a certain height by the rectangular rod, which is convenient for taking the display screen away, and then the electric push rod is operated to extend a certain distance to make the L-shaped rod return to its original position, and the second spring returns to its original state to push the stop block and the extrusion rod back to their original positions, so that the round block descends on the inner wall of the circular groove and the rectangular rod enters the inside of the card slot, further improving the convenience of the polishing device when used.

[0017] Preferably, the side of the inclined block close to the stopper is an inclined surface, and the side of the stopper close to the inclined block is an inclined surface.

[0018] The effect achieved by the above components is: by setting the side of the inclined block close to the stopper as an inclined surface and the side of the stopper close to the inclined block as an inclined surface, it is easier to push the stopper to move when the inclined block enters the stopper surface and is not easy to get stuck on one side of the stopper.

[0019] Preferably, two limit blocks are fixedly connected to one side of the support rod, and the second spring moves between the two limit blocks when compressed.

[0020] The effect achieved by the above-mentioned components is: the outer surface shape of the second spring is reinforced by the limit block, so as to avoid lateral distortion of the second spring when it is deformed, which may affect the normal use of the second spring.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are: In the present invention, by setting a positioning device, when polishing the display screen panel, the display screen panel is placed on the outer surface of the tray, so that the two ends of the display screen are in contact with one side of the two positioning rods and the positioning rods are pushed to move to adapt to the size of the display screen, and the slider is pushed by the first spring to make one side of the positioning rod fit to the outside of the display screen, and the metal sheet is expanded by operating the electric push rod to fix the position of the round rod and the positioning rod, so that the display screen is fixed on the surface of the tray, and there is no need to install different positioning components according to the size of the tray, thereby improving the convenience and flexibility when using the polishing device.
