Description

Technical Field

[0001] The present invention relates to the technical field of liquid crystal glass feeding, in particular to an automatic feeding and assembling machine for liquid crystal glass. Background Art

[0002] When processing liquid crystal glass, it usually needs to be loaded by a robot. The existing robot generally uses a driving mechanism to drive the suction cup downward. The external air source generates negative pressure, causing the suction cup to adsorb the surface of the liquid crystal glass. Then, the liquid crystal glass is clamped by the negative pressure, and then the driving mechanism transfers the liquid crystal glass to the equipment to complete the loading.

[0003] Among them, the transmission of liquid crystal glass mostly adopts adsorption-type manipulator. After reaching the top of the required position, air is transmitted to the inside of the suction cup, so that the suction cup relaxes and loses pressure, and the liquid crystal glass falls on the conveyor belt. In the above process, in order to ensure the smooth fall of the glass, the suction cup is close to the conveyor belt, and after the adsorption force inside the suction cup disappears, the suction cup will protrude outward for a short distance, causing the suction cup to still be in contact with the outer wall of the liquid crystal glass. At this time, the movement of the manipulator will increase the distance between the suction cup and the liquid crystal glass, and a secondary negative pressure will be formed inside the suction cup again, causing the metal wire to drive the suction cup to move twice. In response to the above problems, the following solutions are proposed. Summary of the Invention

[0008] Preferably, the transmission component includes a rubber suction cup connected to the end of the sliding tube away from the air pressure box, an output tube is connected to the outer wall of the sliding tube, and a flow groove is provided at the bottom of the output tube; Among them, after the negative pressure generated by the pressure component reaches the inner wall of the air pressure box, it is transmitted to the rubber suction cup through the sliding tube 1, so that the rubber suction cup adsorbs the outer wall of the glass, and the sliding plate slides to transfer the glass to the desired position.

[0009] Preferably, the pressure-applying assembly includes a sealing ring 1 connected through the side wall of the air pressure box, and a transmission pipe is connected through the side wall of the sealing ring 1; The external air pump transmits the external high-pressure gas to the inside of the air pressure box through the transmission pipe and the sealing ring, or the external air pump extracts the gas inside the transmission pipe and the sliding pipe through the transmission pipe.

[0010] Preferably, the linkage assembly includes a piston block slidably connected to the inner wall of the sliding tube, the inner wall of the sliding tube is provided with a through-hole groove, the bottom of the sliding bracket is fixedly connected to the fixing rod, the bottom of the piston block is fixedly connected to the fixing rod, and the end of the fixing rod away from the fixing rod is fixedly connected to the outer wall of the sliding baffle; When the negative pressure reaches the inner wall of the sliding tube 1, the piston block will slide upward along the inner wall of the sliding tube 1 due to the extraction of the negative pressure air.

[0011] Preferably, the limiting assembly includes a sliding column fixedly connected to the top of the sliding bracket, the top of the sliding bracket is fixedly connected to a spring 1, and an end of the spring 1 away from the sliding bracket is fixedly connected to the bottom of the piston block; Among them, when the linkage assembly slides upward, the starting mechanism drives the sliding bracket to move upward synchronously through the sliding column, and forces the spring to deform, thereby accumulating mechanical power.

[0012] Preferably, the support assembly includes a sliding rod slidably connected to the inner wall of the second sealing ring, the top of the sliding rod is fixedly connected to the second sliding bracket, and the two ends of the second sliding bracket are fixedly connected to the tops of the two sliding columns; When the piston block slides upwards due to the negative pressure, the second sliding bracket will drive the sliding rod to slide upwards synchronously along the inner wall of the second sealing ring.

[0013] Preferably, the blocking assembly includes a push rod fixedly connected to the bottom of the sliding rod, an end of the push rod away from the second sliding bracket is fixedly connected to a pressure rod, and two ends of the pressure rod are fixedly connected to two conical rubber blocks; The sliding rod drives the pressure rod to move upward synchronously through the push rod, and the pressure rod drives the two conical rubber blocks to move upward synchronously to block the flow slot.

[0014] The present invention has the following beneficial effects: (1) During adsorption, the conical rubber block blocks the flow groove, and the sliding baffle blocks the sliding track, so that the sliding tube and the inner space of the rubber suction cup form a closed environment; during pressure relief, external air can enter the inner wall of the rubber suction cup through the flow groove and the above gaps. Through the application of the above components, the rubber suction cup can change the flow state between the internal space and the external environment according to different positions, effectively avoiding the situation where the rubber suction cup has secondary adsorption when the equipment is placed on the glass, causing the position of the liquid crystal glass to be misaligned, and affecting the production line processing efficiency.

[0015] (2) The present invention addresses the problem that the corners of liquid crystal glass are more likely to break under pressure, and changes the conventional adsorption method. Unlike conventional adsorption, after high pressure enters the inner wall of the air pressure box, the piston block blocks the through-hole groove, so that the top of the piston block is in a high pressure state, while the bottom is still in a low pressure state. The low air pressure at the bottom forces the rubber suction cup to be in an adsorption state, and as the sliding baffle slides downward, the sliding bracket 2 will ensure that the sliding efficiency of the two piston blocks is equal. Through the application of the above components, the conventional rubber suction cup directly sprays high-pressure gas, and communicates with the external environment through the flow groove, so that when discharging the material, multiple rubber suction cups are uniformly in a pressure-free state, effectively avoiding the problem that the rubber suction cup will fall off prematurely due to slight deformation inside the rubber suction cup after long-term use, when the rubber suction cup adsorbs the larger liquid crystal glass of the flat panel lamp.

[0016] (3) The present invention utilizes the above-mentioned characteristics of the piston block sliding up and down. When the negative pressure rings on the upper and lower parts of the piston block are equal, the spring 1 will drive the piston block to slide down along the inner wall of the sliding tube 1 and block the outer wall of the through-hole groove. At this time, the piston block divides the space into two parts, one part is the inner wall of the air pressure box at the top of the piston block, and the other part is the bottom of the piston block on the inner wall of the sliding tube 1. At this time, the negative pressures on the upper and lower parts of the piston block are equal. When the transmission tube transmits high-pressure gas into the inner wall of the air pressure box, a high-pressure environment is formed inside the air pressure box, while the bottom of the piston block is still a negative pressure environment. At this time, the piston block is pushed by the high pressure at the top and pulled by the low pressure at the bottom, which will quickly drive the fixed rod to slide downward to complete the degassing. Through the application of the above-mentioned components, compared with the conventional jet design, sufficient air needs to be injected into the rubber suction cup to eliminate the negative pressure suction inside the rubber suction cup. In the above design, after the sliding baffle slides down a short distance, the external air will be quickly replenished to the inner wall of the rubber suction cup through the circulation groove, thereby improving the unloading speed of the rubber suction cup.

[0017] (4) The present invention utilizes the characteristic that the piston block drives the sliding bracket 2 to slide up and down, and sets a limiting mechanism inside the device. When the sliding bracket 2 moves up, the sliding bracket 2 drives the push rod and the pressure rod to slide upward synchronously through the sliding rod, and forces the conical rubber block to block the inner wall of the circulation groove, preventing the sliding connection position between the sliding baffle and the sliding track from causing the adsorption force of the rubber suction cup to decrease due to pressure relief.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0023] The starting mechanism 1 comprises: The transmission component 11 is fixedly connected to the outer wall of the output shaft of the driving motor 15 through a transmission member; The transmission member includes a sliding bracket 111 slidably connected to the inner wall of the driving motor 15. The bottom of the sliding bracket 111 is fixedly connected to the air pressure box 112. The bottom of the air pressure box 112 is connected to two sliding tubes 113. A pressure component 12 is fixedly disposed on the outer wall of the air pressure box 112; Before use, the pressure component 12 is first connected to the air outlet of the external air pump, and it is ensured that the high-pressure gas or negative pressure suction generated by the air pump can be transmitted to the inner wall of the air pressure box 112 through the pressure component 12.

[0024] The transmission mechanism 2 includes: The linkage assembly 21 is provided on the inner wall of the sliding tube 113 via a sliding member; The sliding member includes a sliding track 211 fixedly connected to the inner wall of the sliding tube 113, and a sliding baffle 214 is slidably connected to the inner wall of the sliding track 211; The limiting component 22 is slidably disposed on the inner wall of the sliding tube 113 through an obstruction member; The inner wall of the sliding tube 113 is slidably connected to a sliding bracket 221; When the linkage assembly 21 slides due to the negative pressure, the linkage assembly 21 drives the sliding baffle 214 to slide upward.

[0025] The limiting mechanism 3 includes: Support assembly 31, support assembly 31 is fixedly connected to the inner wall of the air pressure box 112 through a linkage; The linkage member includes a sealing ring 2 312 fixedly connected to the inner wall of the through hole of the air pressure box 112; The blocking component 32 is fixedly connected to the bottom of the supporting component 31 to block the transmission component 11; When the negative pressure inside the air pressure box 112 increases, the linkage assembly 21 will drive the support assembly 31 to move synchronously, and at the same time drive the blocking assembly 32 to slide synchronously.

[0026] For example 2, please refer to Figure 3-Figure 8 The present invention is an automatic loading and assembly machine for liquid crystal glass. Based on Example 1, the transmission component 11 includes a rubber suction cup 114 connected to the end of the sliding tube 113 away from the air pressure box 112. The outer wall of the sliding tube 113 is connected to an output tube 115, and the bottom of the output tube 115 is provided with a flow groove 116. Among them, after the negative pressure generated by the pressure component 12 reaches the inner wall of the air pressure box 112, it is transmitted to the rubber suction cup 114 through the sliding tube 113, so that the rubber suction cup 114 absorbs the outer wall of the glass, and the sliding plate 14 slides to transfer the glass to the desired position.

[0027] The pressure assembly 12 includes a sealing ring 121 that is connected to the side wall of the air pressure box 112, and a transmission pipe 122 is connected to the side wall of the sealing ring 121; Before use, first fix the fixed bracket 13 in the desired position to ensure that the sliding plate 14 can slide along the outer wall of the fixed bracket 13. Then, an external air pump transmits external high-pressure gas to the interior of the air pressure box 112 through the transmission tube 122 and the sealing ring 121, or the external air pump extracts gas from the transmission tube 122 and the sliding tube 113 through the transmission tube 122. When the sliding plate 14 slides to the top of the liquid crystal glass, the drive motor 15 is turned on, and the drive motor 15 forces the rubber suction cup 114 to adhere tightly to the outer surface of the glass through the sliding bracket 111. The external air pump transmits the external high-pressure gas to the inside of the air pressure box 112 through the transmission pipe 122 and the sealing ring 121, or the external air pump extracts the gas inside the transmission pipe 122 and the sliding pipe 113 through the transmission pipe 122.

[0028] The linkage assembly 21 includes a piston block 212 slidably connected to the inner wall of the sliding tube 113. The inner wall of the sliding tube 113 is provided with a through-hole slot 213. The bottom of the sliding bracket 221 is fixedly connected to a fixing rod 215. The bottom of the piston block 212 is fixedly connected to the fixing rod 215. The end of the fixing rod 215 away from the fixing rod 215 is fixedly connected to the outer wall of the sliding baffle 214. As the piston block 212 slides upward, the piston block 212 drives the sliding bracket 221 upward via the sliding column 222. At this time, the spring 1 223 is compressed and deformed, accumulating mechanical power. When the sliding bracket 221 moves upward, the fixed rod 215 is blocked against the side wall of the output tube 115 via the sliding baffle 214, so that the inner wall of the sliding tube 113 forms a sealed environment. When the lowest position of the piston 212 exceeds the lowest position of the through-hole groove 213, the negative pressure at the top of the piston 212 will pass through the gap between the piston 212 and the through-hole groove 213 to reach the bottom of the piston 212, causing the negative pressure to adsorb the liquid crystal glass through the rubber suction cup 114. At this time, the sliding plate 14 can drive the liquid crystal glass to move horizontally through the starting mechanism 1. When the negative pressure reaches the inner wall of the sliding tube 113 , the piston block 212 will slide upward along the inner wall of the sliding tube 113 due to the extraction of the negative pressure air.

[0029] The limiting assembly 22 includes a sliding post 222 fixedly connected to the top of the sliding bracket 221. The top of the sliding bracket 221 is fixedly connected to a spring 1 223. The end of the spring 1 223 away from the sliding bracket 221 is fixedly connected to the bottom of the piston block 212. When the glass needs to be adsorbed, the external air pump draws air from the air pressure box 112, causing the air pressure inside the air pressure box 112 to change to a negative pressure. At this time, the negative pressure forces the two piston blocks 212 to slide upward along the inner wall of the sliding tube 113 and drives the sliding bracket 2 311 to move upward synchronously. When the linkage assembly 21 slides upward, the starting mechanism 1 drives the sliding bracket 221 to move upward synchronously through the sliding column 222, and forces the spring 1 223 to deform, thereby accumulating mechanical power. Since the pressure inside the air pressure box 112 and between the sliding tube 113 is in a balanced state, the spring 1 223 will release the mechanical power at this time, forcing the piston block 212 to slide downward, so that the piston block 212 is blocked against the side wall of the through hole groove 213 again, so that the air pressure box 112 and the sliding tube 1 113 are no longer in a state of circulation.

[0030] The support assembly 31 includes a sliding rod 313 slidably connected to the inner wall of the second sealing ring 312. The top of the sliding rod 313 is fixedly connected to the second sliding bracket 311. The two ends of the second sliding bracket 311 are fixedly connected to the tops of the two sliding columns 222. When the sliding plate 14 needs to reach the specified position and the pressure is released, the transmission pipe 122 generates high-pressure air and transmits it into the inner wall of the air pressure box 112, so that the pressure inside the air pressure box 112 changes from negative pressure to high pressure. At this time, the piston block 212 will be affected by the high pressure and push the sliding bracket 221 to slide downward synchronously. At this time, the sliding bracket 221 drives the sliding baffle 214 to slide downward synchronously through the fixed rod 215, so that a gap for air circulation is formed between the top of the sliding baffle 214 and the sliding track 211, so that external air can enter the inner wall of the rubber suction cup 114 through the circulation groove 116 and the above gaps. Through the application of the above components, the internal space of the rubber suction cup 114 is in a closed state when the suction cup is adsorbed, and when the pressure is released, the internal space of the rubber suction cup 114 is in a flow state with the external space through the output pipe 115 and the flow groove 116, which effectively avoids the rubber suction cup 114 from being adsorbed again when the equipment is placed on the glass. When the piston block 212 slides upward due to the negative pressure, the second sliding bracket 311 will drive the sliding rod 313 to slide upward along the inner wall of the second sealing ring 312 synchronously.

[0031] The blocking assembly 32 includes a push rod 321 fixedly connected to the bottom of the sliding rod 313. The end of the push rod 321 away from the second sliding bracket 311 is fixedly connected to a pressure rod 322. The two ends of the pressure rod 322 are fixedly connected to two conical rubber blocks 323. The sliding rod 313 drives the pressure rod 322 to move upward synchronously through the push rod 321, and the pressure rod 322 drives the two conical rubber blocks 323 to move upward synchronously to block the flow slot 116; Taking advantage of the characteristic that the piston block 212 drives the sliding bracket 2 311 to slide up and down, a limiting mechanism 3 is set inside the device. When the sliding bracket 2 311 moves upward, the sliding bracket 2 311 drives the push rod 321 and the pressure rod 322 to slide upward synchronously through the sliding rod 313, and forces the conical rubber block 323 to block the inner wall of the circulation groove 116, preventing the sliding connection position between the sliding baffle 214 and the sliding track 211, and causing the adsorption force of the rubber suction cup 114 to decrease due to pressure relief.

[0032] A specific application of this embodiment is as follows: before use, the present invention is first fixed to a desired position, ensuring that the sliding plate 14 can slide along the outer wall of the fixed bracket 13, and an external air pump transmits external high-pressure gas to the interior of the air pressure box 112 through the transmission tube 122 and the sealing ring 121, or the external air pump extracts gas from the transmission tube 122 and the sliding tube 113 through the transmission tube 122. When the sliding plate 14 slides to the top of the liquid crystal glass, the drive motor 15 is operated, and the drive motor 15 forces the rubber suction cup 114 to adhere tightly to the outer surface of the glass through the sliding bracket 111; When the glass needs to be adsorbed, the external air pump draws air from the air pressure box 112, causing the air pressure inside the air pressure box 112 to change to a negative pressure. At this time, the negative pressure forces the two piston blocks 212 to slide upward along the inner wall of the sliding tube 113 and drives the sliding bracket 2 311 to move upward synchronously. When the piston block 212 slides upward, the piston block 212 drives the sliding bracket 221 upward through the sliding column 222. At this time, the spring 1 223 is compressed and deformed, and mechanical power is accumulated. When the sliding bracket 221 moves upward, the fixed rod 215 is blocked against the side wall of the output tube 115 through the sliding baffle 214, so that the inner wall of the sliding tube 113 forms a sealed environment. When the lowest position of the piston block 212 exceeds the lowest position of the through-hole groove 213, the negative pressure at the top of the piston block 212 will pass through the gap between the piston block 212 and the through-hole groove 213 to reach the bottom of the piston block 212, so that the negative pressure adsorbs the liquid crystal glass through the rubber suction cup 114. At this time, the sliding plate 14 can drive the liquid crystal glass to move horizontally through the starting mechanism 1. When the above process is in use, since the pressure inside the air pressure box 112 and between the sliding tube 113 is in a balanced state, the spring 1 223 will release the mechanical power, forcing the piston block 212 to slide downward, so that the piston block 212 is blocked against the side wall of the through hole groove 213 again, so that the air pressure box 112 and the sliding tube 1 113 are no longer in a state of circulation.

[0033] When the sliding plate 14 reaches the specified position and the pressure is released, the transmission pipe 122 generates high-pressure air and transmits it into the inner wall of the air pressure box 112, so that the pressure inside the air pressure box 112 changes from negative pressure to high pressure. At this time, the piston block 212 will be affected by the high pressure and push the sliding bracket 221 to slide downward synchronously. At this time, the sliding bracket 221 drives the sliding baffle 214 to slide downward synchronously through the fixed rod 215, so that a gap for air circulation is formed between the top of the sliding baffle 214 and the sliding track 211, so that external air can enter the inner wall of the rubber suction cup 114 through the circulation groove 116 and the above gaps. Through the application of the above components, the internal space of the rubber suction cup 114 is in a closed state when the suction cup is adsorbed, and when the pressure is released, the internal space of the rubber suction cup 114 is in a flow state with the external space through the output pipe 115 and the flow groove 116, which effectively avoids the rubber suction cup 114 from being adsorbed again when the equipment is placed on the glass. In addition, by utilizing the characteristic that the piston block 212 drives the sliding bracket 2 311 to slide up and down, a limiting mechanism 3 is set inside the device. When the sliding bracket 2 311 moves upward, the sliding bracket 2 311 drives the push rod 321 and the pressure rod 322 to slide upward synchronously through the sliding rod 313, and forces the conical rubber block 323 to block the inner wall of the circulation groove 116, preventing the sliding connection position of the sliding baffle 214 and the sliding rail 211 from causing the adsorption force of the rubber suction cup 114 to decrease due to pressure relief.
