Description

Technical Field

[0001] This invention relates to the field of display substrate transfer and clamping device technology, specifically a display substrate transfer and clamping device for display screen production. Background Technology

[0002] A display screen is a device that converts electronic documents or other forms of input information into visual images and text through the interaction of optics and electronics. The display substrate refers to the material used to support and connect electronic components in display devices such as liquid crystal displays (LCDs) and LEDs. Display substrates are generally made of materials such as glass or plastic. Glass is the main substrate material used in LCD displays and occupies an important position in the LCD field. Especially driven by the consumer trend of lightweight and ultra-thin mobile digital devices, ultra-thin glass used in touch panels and display panels of electronic products has become a key raw material for upstream products in the electronic information display industry. In the production process, transfer and clamping devices are required. The core functions of clamping and transfer devices are clamping and transfer. The clamping function is achieved through specific clamping mechanisms (such as grippers, clamping parts, etc.) that can firmly grasp items and prevent them from slipping or being damaged during transfer. The transfer function is achieved through robotic arms, conveyor belts, or other moving mechanisms that can move the clamped items from one position to another. These devices are designed to improve production efficiency, reduce manual labor, ensure the safety and integrity of items, and optimize the entire logistics process. Examples include conveyor belts and forklifts.

[0003] However, most transfer devices use suction cups for fixation. During the transfer process, the suction force may be insufficient, causing the substrate to become skewed, loose, or fall off, resulting in product damage, increased costs, and safety risks to workers. Summary of the Invention

[0004] The purpose of this invention is to provide a display substrate transfer and clamping device for display production, which reasonably solves the problem that most transfer devices use suction cups for fixing. During the transfer process, the suction force may be insufficient, or the display substrate may become skewed, loose, or fall off, resulting in product damage, increased costs, and affecting the safety of workers.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a display substrate transfer and clamping device for display production, comprising a conveyor belt, a movable component with a moving function fixedly installed on the conveyor belt, a fixed component with a clamping and fixing function fixedly installed on the movable component, the movable component including a first telescopic cylinder and a second telescopic cylinder, a U-shaped frame with fixing and moving functions fixedly installed on the first telescopic cylinder, a hollow frame with a moving space function fixedly installed under the U-shaped frame, a fixing block with a fixing function fixedly installed on one side of the hollow frame, an L-shaped piston rod with a driving function fixedly installed on the second telescopic cylinder, the fixed component including a vacuum pump, a telescopic pipe with transmission and telescopic adjustment functions fixedly installed at one end of the vacuum pump, a first L-shaped pipe with a transmission function fixedly installed on one side of the telescopic pipe, a suction cup with a fixing function fixedly installed on one side of the first L-shaped pipe, a second L-shaped pipe with a transmission function fixedly installed on one side of the suction cup, an inflation pipe with a transmission function fixedly installed on the other side of the vacuum pump, and a protective air cushion with a protective function fixedly installed on the inflation pipe.

[0006] Preferably, a drive shaft with a rotational function is installed at the motor output, and a conveyor belt with a rotational function is installed on the drive shaft. A drive shaft with a rotational function is also installed on the other side of the conveyor belt for power transmission, so that the conveyor belt moves.

[0007] Preferably, both sides of the drive shaft are fixedly mounted with column legs for supporting and fixing the operation of the overall device. A fixing frame for fixing is fixedly mounted on one side of each column leg. A motor for providing power is fixedly mounted on the fixing frame for supporting and fixing the motor. Movable slots for providing a moving space are installed between each column leg.

[0008] Preferably, a rotating roller is installed at the lower end of the hollow frame, the roller is slidably mounted on the moving groove, the roller slides on the moving groove, and the auxiliary moving component moves with the conveyor belt through the fixed block.

[0009] Preferably, both the first telescopic cylinder and the second telescopic cylinder are fixedly installed on the hollow frame and move together with the hollow frame.

[0010] Preferably, one end of the air pump is provided with an air extraction port to extract air for inflating the protective air cushion, thereby protecting the display substrate placed on the protective air cushion and preventing damage to the display substrate during movement.

[0011] Preferably, the suction cup is provided with a piston block that has an air-evacuating function to evacuate the air inside the suction cup, so that the suction cup can be tightened to fix the display substrate and prevent the display substrate from being damaged during movement.

[0012] Preferably, an L-shaped piston rod is fixedly installed on the piston block, which is used to drive the piston block to move and extract air from the suction cup.

[0013] Preferably, a telescopic pipe with transmission and telescopic adjustment functions is also fixedly installed on one side of the second L-shaped pipe, and a third L-shaped pipe with transmission functions is fixedly installed on one side of the telescopic pipe.

[0014] Preferably, a gear valve with opening and closing function is fixedly installed on one side of the third L-shaped pipe, and a toothed belt with meshing function is fixedly installed on one side of the moving groove. When the gear valve moves onto the toothed belt, the toothed belt meshes with the gear valve, and the toothed belt drives the gear valve to rotate, thus opening the gear valve.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. When the motor provides power, the conveyor belt rotates, and the fixed block moves along with the conveyor belt, driving the entire moving component to move. Rollers are installed at the lower end of the hollow frame for sliding. The rollers are slidably mounted on the moving groove and connected to each other. The rollers slide on the moving groove, and the auxiliary moving component moves along with the conveyor belt via the fixed block. The first telescopic cylinder retracts, and the U-shaped frame moves downward, thereby driving the suction cup to pick up the display substrate. An L-shaped piston rod is fixedly installed on the second telescopic cylinder to connect to the piston block. When the second telescopic cylinder rises, the piston block also moves upward, causing the piston block to move upward inside the suction cup. When the U-shaped frame drives the piston block downward, picking up the display substrate, the second telescopic cylinder... The L-shaped piston rod drives the piston block to move upward inside the suction cup, thereby sucking up the air inside the second telescopic cylinder. The air is then transferred from the second L-shaped pipe to the telescopic pipe. At the same time, the air pump draws air through an air extraction port at one end to inflate the protective air cushion. This inflates the display substrate placed on the protective air cushion to protect it from collisions. The telescopic pipe is fixedly installed at one end of the air pump. Air is drawn from the telescopic pipe, and the gas is simultaneously injected into the protective air cushion, causing it to expand and protect the placed display substrate from collisions. Meanwhile, the air drawn from inside the suction cup makes the suction cup more secure and stable on the display substrate, preventing damage during transportation due to insufficient suction.

[0017] 2. When the gear valve moves onto the toothed belt, the toothed belt meshes with the gear valve, causing the gear valve to rotate. The gear valve opens, and the gas inside the protective air cushion is delivered to the suction cup through the third L-shaped pipe, the telescopic pipe, the second L-shaped pipe, and the piston block. The suction cup slowly releases the display substrate. This effectively solves the problem that most transfer devices use suction cups for fixing, which may result in weak adhesion, misalignment, or even the display substrate falling off due to factors such as suction force, leading to product damage, increased costs, and safety concerns for workers.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] The present invention provides a display substrate transfer and clamping device for display production, including a conveyor belt 1, a movable component 2 with a moving function fixedly installed on the conveyor belt 1, and a fixed component 3 with a clamping and fixing function fixedly installed on the movable component 2.

[0028] See Figures 1 to 4 As shown, both sides of the drive shaft 102 are fixedly mounted with column legs 103 for supporting and fixing the operation of the overall device. A fixing frame 104 for fixing is fixedly mounted on one side of the column leg 103. A motor 101 for providing power is fixedly mounted on the fixing frame 104 for supporting and fixing the stable operation of the motor 101. Movable slots 105 for providing a moving space are installed between the column legs 103.

[0029] See Figures 5 to 6 As shown, the moving component 2 includes a first telescopic cylinder 201 and a second telescopic cylinder 204 for driving other devices to telescopically move. Both the first telescopic cylinder 201 and the second telescopic cylinder 204 are fixedly mounted on the hollow frame 203 and move together with the hollow frame 203. When operation begins, the first telescopic cylinder 201 retracts, causing the U-shaped frame 202, which is fixedly mounted on the first telescopic cylinder 201 and has both fixing and moving functions, to move downwards. The U-shaped frame 202 is located inside the hollow frame 203, which provides a moving space, and moves downwards within the hollow frame 203. A fixing block 206 with a fixing function is fixedly mounted on one side of the hollow frame 203 for fixation. The fixing block 206 is fixedly mounted on the conveyor belt 1. When the motor 101 lifts... The power source drives the drive shaft 102 to rotate, thereby driving the conveyor belt 1 to rotate. The fixed block 206 moves with the conveyor belt 1, driving the entire moving component 2 to move. The lower end of the hollow frame 203 is equipped with rollers 207 for sliding. The rollers 207 are slidably installed on the moving groove 105 and connected to each other. The rollers 207 slide on the moving groove 105. The auxiliary moving component 2 moves with the conveyor belt 1 through the fixed block 206. The second telescopic cylinder 204 is fixedly equipped with an L-shaped piston rod 205 with a driving function, which is used to connect the piston block 307. When the second telescopic cylinder 204 rises, 205 also moves upward with the second telescopic cylinder 204, causing the piston block 307 to move upward inside the suction cup 304.

[0030] See Figure 7As shown, the fixing component 3 includes an air pump 301 for air extraction, an inflation pipe 305 fixedly installed on the other side of the air pump 301 for gas transmission, a protective air cushion 306 fixedly installed on the inflation pipe 305 to protect the placed display substrate, a telescopic pipe 311 for transmission and telescopic adjustment for gas transmission and auxiliary device movement adjustment at one end of the air pump 301, a first L-shaped pipe 303 for gas transmission fixedly installed on one side of the telescopic pipe 311, and a suction cup 304 for fixing the display substrate to prevent damage to the display substrate during movement. 4. An internally installed piston block 307 with a suction function assists in fixing the display substrate by suction. An L-shaped piston rod 205 with a driving function is fixedly installed on the piston block 307. The L-shaped piston rod 205 can drive the piston block 307 to move and suction the suction cup 304 to remove the air inside the suction cup 304, so that the suction cup 304 can be tightened to fix the display substrate. A second L-shaped pipe 308 with a transmission function is fixedly installed on one side of the suction cup 304 to transmit gas. A telescopic pipe 311 with transmission and telescopic adjustment functions is also fixedly installed on one side of the second L-shaped pipe 308 to transmit gas and for the auxiliary device to move and adjust. One side of the telescopic pipe 311 is connected to a 310 for transmitting gas.A third L-shaped pipe 310 with a transmission function is fixedly installed on one side of the protective air cushion 306 to transmit gas. A gear valve 309 with an opening and closing function is fixedly installed on one side of the third L-shaped pipe 310 to open and close the gas transmission channel. When the U-shaped frame 202 drives the piston block 307 to move downward and suck up the display substrate, the second telescopic cylinder 204 rises and drives the piston block 307 to move upward inside the suction cup 304 through the L-shaped piston rod 205, thereby sucking up the air inside the second telescopic cylinder 204 and transferring it from the second L-shaped pipe 308 to the telescopic pipe 311. At the same time, the air pump 301 evacuates air. Air is extracted through the air extraction port 302 at one end of the air pump 301 to inflate the protective air cushion 306, protecting the display substrate placed on the protective air cushion 306 from collision. The telescopic pipe 311 is fixedly installed at one end of the air pump 301 to evacuate air from the telescopic pipe 311. Simultaneously, gas is injected into the protective air cushion 306, causing it to expand and protect the placed display substrate from impact. Meanwhile, the air drawn from the suction cup 304 makes the suction cup 304 more secure and stable against the display substrate, preventing damage during transport due to insufficient suction. A toothed belt 106 with meshing function is fixedly installed on one side of the moving groove 105. When the gear valve 309 moves onto the toothed belt 106, the toothed belt 106 meshes with the gear valve 309, causing the gear valve 309 to rotate and open. The gas inside the protective air cushion 306 is then transported to the suction cup 304 through the third L-shaped pipe 310, the telescopic pipe 311, the second L-shaped pipe 308, and the piston block 307. The suction cup 304 slowly releases the display substrate, preventing insufficient suction from hindering proper placement after transport.

[0031] Working principle: At the start of operation, when motor 101 provides power, it drives drive shaft 102 to rotate, thereby rotating conveyor belt 1. Fixed block 206 moves along with conveyor belt 1, causing the entire moving assembly 2 to move. Rollers 207 are mounted on the lower end of hollow frame 203 for sliding. Rollers 207 are slidably mounted on moving groove 105 and interconnected. The auxiliary moving assembly 2 moves along with conveyor belt 1 via fixed block 206. First, the first telescopic cylinder 201 is activated to retract, causing the U-shaped frame 202 fixed on the first telescopic cylinder 201 to move... As the U-shaped frame 202 moves downwards, the suction cup 304 follows the downward movement of the U-shaped frame 202, initially gripping the display substrate. Then, the second telescopic cylinder 204, on which an L-shaped piston rod 205 is fixedly mounted, connects to the piston block 307. As the second telescopic cylinder 204 rises, the piston rod 205 also moves upwards, causing the piston block 307 to move upwards within the suction cup 304. When the U-shaped frame 202 moves the piston block 307 downwards, gripping the display substrate, the second telescopic cylinder 204 rises, and the L-shaped piston rod 205 moves the piston block 307 upwards within the suction cup 304, thus activating the second telescopic cylinder. Air inside cylinder 204 is transferred to telescopic pipe 311 through second L-shaped pipe 308. Simultaneously, air pump 301 draws air through an air extraction port 302 at one end to inflate protective air cushion 306, protecting the display substrate placed on it from impacts. Telescopic pipe 311 is fixedly installed at one end of air pump 301; air is drawn through telescopic pipe 311, simultaneously filling the protective air cushion 306 and causing it to expand, further protecting the display substrate from impacts. Meanwhile, air drawn from suction cup 304 causes the suction cup 304 to... The display substrate is more secure and stable, preventing damage during transport due to insufficient suction. When the gear valve 309 moves onto the toothed belt 106, the toothed belt 106 meshes with the gear valve 309, causing the gear valve 309 to rotate and open. The gas inside the protective air cushion 306 is then transported to the suction cup 304 through the third L-shaped pipe 310, the telescopic pipe 311, the second L-shaped pipe 308, and the piston block 307. The suction cup 304 slowly releases the display substrate, preventing the display substrate from being placed too easily after transport due to excessive suction.
