Description

Technical Field

[0001] The invention relates to the technical field of display substrate transfer clamping devices, and in particular to a display substrate transfer clamping device for display screen production. Background Art

[0002] A display screen is a device that converts electronic documents or other forms of input information into visible images and text through the interaction of optics and electricity. The display substrate of a display screen refers to the electronic components used to support and connect display devices such as liquid crystal and LED. The display substrate is generally made of materials such as glass or plastic. Glass is the main substrate material used for liquid crystal displays and occupies an important position in the field of liquid crystal displays. In particular, driven by the lightweight and ultra-thin consumer trend of mobile digital devices, the ultra-thin glass used for touch panels and display panels of electronic products has become a key raw material product base material in the upstream of the electronic information display industry. In the production process, a transfer clamping device is required. The core functions of the clamping and transfer device are clamping and transfer. The clamping function is realized by a specific clamping mechanism (such as a gripper, a clamping piece, etc.), which can firmly grasp the object to prevent it from slipping or being damaged during the transfer process. The transfer function is realized by a mechanical arm, a conveyor belt or other moving mechanism, which can move the clamped object from one position to another.

The telescopic pipe is fixedly installed at one end of the air pump, and air is extracted from the telescopic pipe. The gas is simultaneously poured into the protective air cushion to expand it, so as to protect the placed display substrate and prevent collision. At the same time, the air extracted from the suction cup makes the suction cup 304 more firm and stable to the display substrate, so as to prevent damage during transportation due to insufficient suction force. 2. When the gear valve moves to the toothed belt, the toothed belt meshes with the gear valve, and the toothed belt drives the gear valve to rotate. The gear valve opens, and the internal gas of the protective air cushion is transported 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, which reasonably solves the problem that most transfer devices use suction cups to fix the substrate. During the transfer process, the adsorption force may be loose, or the actual substrate may be skewed, loosened, or fall off, resulting in product damage, increased costs, and affecting the safety of staff.

A moving groove 105 with a moving place function is installed between the column legs 103, which is used to provide a moving place; See also Figure 5 to Figure 6 As shown, the moving assembly 2 includes a first telescopic cylinder 201 and a second telescopic cylinder 204 for driving other devices to perform telescopic movement. The first telescopic cylinder 201 and the second telescopic cylinder 204 are both fixedly mounted on the hollow frame 203 and move along with the hollow frame 203. When the work starts, the first telescopic cylinder 201 contracts, driving the U-shaped frame 202 with fixing and moving functions fixedly mounted on the first telescopic cylinder 201 to move downward. The U-shaped frame 202 is arranged inside the hollow frame 203 that provides a moving place, moves inside the hollow frame 203, and moves downward. A fixed block 206 with a fixing function is fixedly mounted on one side of the hollow frame 203 for fixing. The fixed block 206 is fixedly mounted on the conveyor belt 1. When the motor 101 is lifted, The power source drives the driving shaft 102 to rotate, thereby driving the conveyor belt 1 to rotate, and the fixed block 206 moves with the conveyor belt 1, driving the moving assembly 2 to move as a whole. The lower end of the hollow frame 203 is installed with a roller 207 for sliding. The roller 207 is slidably installed on the moving groove 105 and connected to each other.

The second telescopic cylinder 204 is fixedly installed with an L-shaped piston rod 205 with a driving effect, 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, so that the piston block 307 is driven to move upward inside the suction cup 304; See also Figure 7As shown, the fixing assembly 3 includes an air pump 301 for pumping air, an air filling pipe 305 is fixedly installed on the other side of the air pump 301 for transmitting gas, a protective air cushion 306 with a protective function is fixedly installed on the air filling pipe 305 to protect the placed display substrate, a telescopic pipe 311 with a transmission and telescopic adjustment function is fixedly installed at one end of the air pump 301 to transmit gas and move and adjust the auxiliary device, a first L-shaped pipe 303 with a transmission function is fixedly installed on one side of the telescopic pipe 311 to transmit gas, and a suction cup 304 with a fixing function is fixedly installed on one side of the first L-shaped pipe 303 to fix the display substrate to prevent the display substrate from being damaged during movement, and the suction cup 304 is fixedly installed on the other side of the first L-shaped pipe 303 to fix the display substrate to prevent the display substrate from being damaged during movement. 4 is provided with a piston block 307 with a pumping function to pump air and assist in fixing the display substrate. The piston block 307 is fixedly installed with an L-shaped piston rod 205 with a driving function, which is used for the L-shaped piston rod 205 to drive the piston block 307 to move and pump air from the suction cup 304 to evacuate the air inside the suction cup 304 so that the suction cup 304 is sucked tightly 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 a transmission and telescopic adjustment function is also fixedly installed on one side of the second L-shaped pipe 308 to transmit gas and move and adjust the auxiliary device. One side of the telescopic pipe 311 is connected with 310 to transmit 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 transmission gas channel. When the U-shaped frame 202 drives the piston block 307 to move downward to suck 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 the air inside the second telescopic cylinder 204 and transferring it to the telescopic pipe 311 from the second L-shaped pipe 308. At the same time, the air pump 301 is used to evacuate air. The air is extracted through the air inlet 302 at one end of the air pump 301 to inflate the protective air cushion 306, protect the display substrate placed on the protective air cushion 306, and prevent collision. The telescopic pipe 311 is fixedly installed at one end of the air pump 301 to evacuate the telescopic pipe 311. , Gas is simultaneously poured into the protective air cushion 306 to expand it, which can protect the placed display substrate and prevent collision. At the same time, the gas extracted from the suction cup 304 makes the suction cup 304 more firm and stable to the display substrate, preventing it from being easily damaged during transportation due to insufficient suction. A toothed belt 106 with a meshing effect 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, and the toothed belt 106 drives the gear valve 309 to rotate. The gear valve 309 opens, and the gas inside the protective air cushion 306 is 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 easily placed after transportation due to excessive suction. ,

[0019] Working principle: When the work starts, when the motor 101 provides the power source, it drives the driving shaft 102 to rotate, thereby driving the conveyor belt 1 to rotate, and the fixed block 206 moves with the conveyor belt 1, driving the moving component 2 to move as a whole, and the lower end of the hollow frame 203 is installed with a roller 207 for sliding, and the roller 207 is slidably installed on the moving groove 105 and connected to each other. The roller 207 slides on the moving groove 105, and the auxiliary moving component 2 moves with the conveyor belt 1 through the fixed block 206. First, the first telescopic cylinder 201 is started to retract, which drives the U-shaped frame 202 fixed on the first telescopic cylinder 201 to move. The suction cup 304 moves downward, following the U-shaped frame 202 to move downward, so that the suction cup first initially sucks the display substrate, and then the second telescopic cylinder 204 is started. An L-shaped piston rod 205 is fixedly installed on the second telescopic cylinder 204, which is used to connect the piston block 307. When the second telescopic cylinder 204 rises, 205 also follows the second telescopic cylinder 204 to move upward, so that the piston block 307 is driven to move upward inside the suction cup 304. When the U-shaped frame 202 drives the piston block 307 to move downward and suck 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 the second telescopic cylinder 204. The air inside the cylinder 204 is transferred from the second L-shaped pipe 308 to the telescopic pipe 311, and the air pump 301 is used to evacuate the air. The air is extracted through the air inlet 302 at one end of the air pump 301 to inflate the protective air cushion 306, so as to protect 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, and the telescopic pipe 311 is evacuated. The gas is simultaneously poured into the protective air cushion 306 to expand it, so as to protect the placed display substrate from collision. At the same time, the air extracted from the inside of the suction cup 304 makes the suction cup 304 inflate the display substrate. The display substrate is more firm and stable to prevent it from being broken during transportation due to insufficient suction. When the gear valve 309 moves to the toothed belt 106, the toothed belt 106 meshes with the gear valve 309, and the toothed belt 106 drives the gear valve 309 to rotate. The gear valve 309 opens, and the internal gas of the protective air cushion 306 is 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 to prevent the display substrate from being easily placed after transportation due to excessive suction.
