Description

Technical Field

[0001] The invention belongs to the technical field of display screen production, and in particular relates to automatic glue dispensing equipment for display screen production. Background Art

[0002] The automatic dispensing equipment used in display production is a highly automated production tool that can improve production efficiency, ensure the accuracy and consistency of dispensing, and reduce labor costs and material waste. These devices usually include pressure control systems, motion control systems, etc., which can achieve precise control and coating of various glues. In the production of liquid crystal displays (LCDs) and touch screens, automatic dispensing equipment is particularly important. They are used to fix and protect circuits and components and ensure the stability and reliability of touch screens. The technical features of automatic dispensing equipment include high automation, high positioning accuracy, easy operation, and an upgradeable automatic dispensing control platform. These features enable the equipment to adapt to product diversification and improvement needs, but it still has the following disadvantages in actual use: During the production process of the display screen, it is necessary to fix the appropriate parts on it by dispensing glue. During the operation, the display screen can only be transported by the operator by placing it on the dispensing equipment one by one, and it is also necessary to coordinate with the installation equipment in it. The operation process requires a lot of manpower, which affects the production efficiency; When dispensing glue on the display screen, it needs to be placed in the appropriate position on the dispensing equipment and the display screen should be clamped during the dispensing process. However, during operation, each clamping device is rigid. When the display screen touches the clamping device, the corners of the display screen are easily damaged due to bumps, and the yield of the display screen after processing is not high enough; During the glue dispensing process of the display screen, the display screen can be transported to the next processing position for the next processing operation by directly applying or dotting the glue on the appropriate position. During the operation, the glue dotted on the surface of the display screen has raised spikes and the applied glue has uneven ripples, which will make the subsequent installation of the bonding structure inconvenient. It is necessary to remove the glue and re-dispense the glue, which affects the efficiency of the display screen processing. Summary of the invention

[0003] The purpose of the present invention is to provide an automatic dispensing device for display screen production. By setting a workbench, a hydraulic cylinder, a fixed sleeve and an electric hoist, the problems of the operator needing to place the display screens one by one during the dispensing process being inconvenient, the display screens being easily damaged by collision with the clamping structure during the process of placing the display screens at the dispensing position, and the glue liquid being easily uneven after coating or dispensing, requiring manual secondary dispensing, affecting the processing efficiency are solved.

[0004] To solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is an automatic glue dispensing device for display screen production, comprising a workbench, a hydraulic cylinder, a fixed sleeve and an electric hoist. A belt conveyor is inlaid and fixed in the center of the top of the workbench. Hydraulic cylinders are symmetrically fixed at the bottom of the workbench on both sides of the belt conveyor. A hydraulic rod is movably connected in the hydraulic cylinder. Electric push rods are arranged on both sides of the workbench. A connecting rod is arranged above the belt conveyor. Photoelectric switches are symmetrically fixed on the top of the workbench below the connecting rod along the center line parallel to the top of the workbench and the long side. A moving track is arranged above the connecting rod. The outer side of the moving track is movably connected to the electric hoist. Fixed sleeves are arranged at the edges of the two short sides of the top of the moving track. When working, the belt conveyor is fixed thereon through the workbench, the display screen is supported thereon through the belt conveyor, the hydraulic rod is driven to rise and fall by the hydraulic cylinder, the suction cup is driven to rise and fall, the baffle is connected to the bottom of the baffle through the connecting rod, the conveying position of the belt conveyor is limited by the baffle, the hydraulic cylinder is fixed therein through the fixed sleeve, and the exhaust nozzle and the glue discharge nozzle are driven to move together by the electric hoist.

[0005] Furthermore, a through hole is provided in the workbench corresponding to the position of the hydraulic rod one, the hydraulic rod one is inserted into the through hole, and the workbench is movably connected to the hydraulic rod one via the through hole.

[0006] Furthermore, a suction cup is fixed to the top of the hydraulic rod 1, and a friction ring is fixed to the upper edge of the outer peripheral surface of the suction cup. When the hydraulic rod 1 is driven by the hydraulic cylinder, the suction cup is driven to rise and is lightly adsorbed on the bottom of the display screen, and the friction is increased by the friction ring to prevent the display screen from shifting during the dispensing process, causing deviation in the dispensing.

[0007] Furthermore, rotating columns are fixed at the top edge of the workbench outside the two corners at one end of the belt conveyor away from the connecting rod, and the top of each rotating column is rotatably connected to a guide roller, and the display screen is guided straightly onto the belt conveyor through the guide rollers on the rotating column.

[0008] Furthermore, baffles are fixed at the two short sides of the bottom of the connecting rod, and a flexible patch is fixed on the side of the baffle close to the center of the top of the workbench. The photoelectric switch is arranged on the side of the flexible patch away from the baffle and at the lower edge of the side of the flexible patch away from the baffle. When the connecting rod is working, it limits the position of the display screen moving on the belt conveyor through the baffle, and prevents the display screen from breaking when it touches the baffle through the flexible patch. When the display screen covers the photoelectric switch, the belt conveyor is temporarily shut down.

[0009] Furthermore, a lifting plate is fixed to the telescopic end of the electric push rod, the baffle extends out of the top edge of the workbench, and the bottom surface of the baffle extending out of the top edge of the workbench is fixed to the top of the lifting plate. The electric push rod drives the lifting plate to move, thereby driving the baffle to move.

[0010] Furthermore, lifting blocks are fixed at both ends of the moving track, a fixed sleeve is provided on the top of the lifting block, a hydraulic cylinder 2 is provided on the upper part of the fixed sleeve, a hydraulic rod 2 is movably connected in the hydraulic cylinder 2, and the bottom end of the hydraulic rod 2 is fixed to the top of the lifting block. A limit strip is fixed on the top of the moving track on the side of the electric hoist away from the top center of the workbench. When the moving track is working, it is lifted and lowered by the lifting block, which drives the moving track to rise and fall, and drives the electric hoist to rise and fall.

[0011] Furthermore, a connecting block is fixed at the center of the bottom of the electric hoist, and an exhaust nozzle and a glue removal nozzle are respectively fixed at two edges of the bottom of the connecting block parallel to the short sides of the top of the workbench. The electric hoist is connected to the exhaust nozzle and the glue removal nozzle through the connecting block, and the exhaust nozzle and the glue removal nozzle are used to dispense glue on the display screen when the electric hoist is driven to move.

[0012] Furthermore, the glue removal nozzle is arranged at the edge of the bottom of the connecting block close to the center of the top of the workbench, one end of the exhaust nozzle is fixedly connected to an air supply pipe, and one end of the glue removal nozzle is fixedly connected to a glue supply pipe. Electric control valves are fixed in the middle of the air supply pipe and the glue supply pipe. When working, the electric control valves are used to control the on and off of the glue liquid in the glue removal nozzle and the air in the exhaust nozzle.

[0013] The present invention has the following beneficial effects: The present invention solves the problem that the operator needs to place the display screen one by one during the dispensing process of the display screen by arranging a workbench and a hydraulic cylinder. When the belt conveyor drives the display screen to be fitted with the flexible patch, the hydraulic cylinder is started to drive the hydraulic rod to be lifted. The lifting of the hydraulic rod drives the suction cup to be lifted. After the suction cup is lifted and contacts the display screen on the belt conveyor, the pressure of the display screen presses the suction cup, and the suction cup slightly adsorbs the display screen. At the same time, the friction ring increases the friction between the display screen and the suction cup, and continues to rise above the connecting rod, so that the suction cup restricts the display screen thereon to prevent the display screen from being separated from the suction cup during the dispensing process. When the dispensing is completed, the hydraulic cylinder is started to drive the suction cup to descend until the display screen is separated from the suction cup, and the display screen is left on the belt conveyor and then transported by the belt conveyor to complete the work. When the display screen is working, it is not necessary to place the glue one by one, and a streamlined operation can be performed, which is convenient to operate and has higher work efficiency.

[0014] The present invention solves the problem that the display screen is easily damaged by collision with the clamping structure during the process of placing the display screen at the glue dispensing position by arranging an electric push rod and a connecting rod. The display screen is conveyed by the belt conveyor until the display screen covers the photoelectric switch and determines that the display screen is restricted in place. At this time, the belt conveyor stops working, and the display screen is restricted in a suitable position by the flexible patch. When the belt conveyor is restarted, the electric push rod is started at the same time to drive the lifting plate to drive the baffle plate to rise above the display screen conveyed on the belt conveyor, so that after the display screen is glued, it is smoothly conveyed to the next work process on the belt conveyor, so that during the glue dispensing process of the display screen, the display screen is directly conveyed to the glue dispensing position and is restricted in position by the guide roller. The edge of the display screen is protected by the flexible patch to prevent the display screen from being damaged due to collision, thereby increasing the yield rate of the display screen after glue dispensing.

[0015] The present invention solves the problem that in the process of glue dispensing on a display screen, the glue liquid is prone to unevenness after coating or dispensing, requiring manual secondary glue dispensing and affecting the processing efficiency by arranging a fixing sleeve, an electric hoist, an exhaust nozzle and a glue discharge nozzle. The electric hoist is started to drive the glue discharge nozzle to move, so that after the surface of the display screen is coated with the glue liquid, it moves away from the display screen. At the same time, high-pressure air is transported to the exhaust nozzle through an air pipe to reduce pressure. The decompressed air sprayed from the exhaust nozzle blows the surface of the glue liquid to flatten the surface of the glue liquid, making the surface of the glue liquid smoother, reducing the number of manual secondary rework of the glue liquid after coating or dispensing in the process of glue dispensing on the display screen, and increasing the processing efficiency.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Specific embodiment 1

[0020] See also Figure 1-9The present invention is an automatic dispensing device for display screen production, including a workbench 1, a hydraulic cylinder 2, a fixed sleeve 5 and an electric hoist 6. A belt conveyor 104 is embedded and fixed in the center of the top of the workbench 1. When working, the display screen transported from the outside is transported to the flexible patch 402 on the bonding baffle 401 through the belt conveyor 104, and the position is restricted by the flexible patch 402. Hydraulic cylinders 2 are symmetrically fixed to the bottom of the workbench 1 on both sides of the belt conveyor 104. A hydraulic rod 201 is movably connected in the hydraulic cylinder 2. The hydraulic rod 201 is driven to rise and fall by the hydraulic cylinder 2, and the suction cup 202 is pushed to rise and fall, slightly adsorbing the display screen to limit the position of the display screen. Electric push rods 3 are arranged on both sides of the workbench 1, and the baffle 401 is driven to rise and fall by the electric push rods 3, so that the display screen can pass through the belt conveyor 104 to a suitable position. A connecting rod 4 is arranged above the belt conveyor 104. The connecting rod 4 connects the baffle 401 thereto, and a photoelectric switch 105 is symmetrically fixed on the top of the workbench 1 below the connecting rod 4 along the center line of the top of the workbench 1 parallel to the long side. The photoelectric switch 105 is covered by the display screen to determine that the display screen is restricted in place, and the electric hoist 6 is started to drive the glue removal nozzle 8 to apply glue on the display screen. At the same time, the high-pressure air entering therein is reduced in pressure through the exhaust nozzle 7 and discharged to the display screen, so that the surface protrusions of the glue coated on the display screen are blown flat. A movable track 602 is arranged above the connecting rod 4, and the outer side of the movable track 602 is movably connected with the electric hoist 6. When the electric hoist 6 is working, it moves on the movable track 602 to drive the exhaust nozzle 7 and the glue removal nozzle 8 to move. Fixed sleeves 5 are arranged at the edges of the two short sides of the top of the movable track 602. When the fixed sleeve 5 is working, the top is fixed on the external supporting structure, and the fixed sleeve 5 fixes the hydraulic cylinder 2 501 therein.

[0021] Specifically, a through hole 103 is provided in the workbench 1 corresponding to the position of the hydraulic rod 201 , and the hydraulic rod 201 is inserted into the through hole 103 . The workbench 1 is movably connected to the hydraulic rod 201 via the through hole 103 .

[0022] Furthermore, a suction cup 202 is fixed to the top of the hydraulic rod 201, and a friction ring 203 is fixed to the upper edge of the outer peripheral surface of the suction cup 202. During operation, when the belt conveyor 104 drives the display screen to move to fit with the flexible patch 402, the hydraulic cylinder 2 is started to drive the hydraulic rod 201 to rise, and the suction cup 202 is driven to rise through the lifting of the hydraulic rod 201. After the suction cup 202 rises and contacts the display screen on the belt conveyor 104, the pressure of the display screen presses the suction cup 202, and the suction cup 202 slightly adsorbs the display screen. At the same time, the friction ring 203 increases the friction between the display screen and the suction cup 202, so that the suction cup 202 restricts the display screen thereon to prevent the display screen and the suction cup 202 from separating during the dispensing process.

[0023] The operation process of this embodiment is as follows: during operation, when the belt conveyor 104 drives the display screen to move to fit with the flexible patch 402, the hydraulic cylinder 2 is started to drive the hydraulic rod 201 to rise, and the suction cup 202 is driven to rise by the lifting of the hydraulic rod 201. After the suction cup 202 rises and contacts the display screen on the belt conveyor 104, the pressure of the display screen causes the suction cup 202 to be compressed, and the suction cup 202 slightly absorbs the display screen. At the same time, the friction ring 203 increases the friction between the display screen and the suction cup 202, and continues to rise above the connecting rod 4, so that the suction cup 202 restricts the display screen thereon to prevent the display screen and the suction cup 202 from separating during the dispensing process. When the dispensing is completed, the hydraulic cylinder 2 is started to drive the suction cup 202 to descend until the display screen 1 is separated from the suction cup 202, and the display screen 1 remains on the belt conveyor 104, and is then transported by the belt conveyor 104 to complete the work. Specific embodiment 2

[0024] See also Figure 1 , 2 , 4, 5, on the basis of the specific embodiment 1, a rotating column 101 is fixed at the top edge of the workbench 1 outside the two corners of one end of the belt conveyor 104 away from the connecting rod 4, and the top of each rotating column 101 is rotatably connected to a guide roller 102, and the workbench 1 is rotatably connected to the guide roller 102 above the workbench 1 through the rotating column 101. When the two guide rollers 102 are working, the edges of the two long sides of the display screen are guided and clamped by the guide rollers 102, and the display screen is guided to the belt conveyor 104 by the guide rollers 102, and is transported by the belt conveyor 104 at the same time.

[0025] Specifically, baffles 401 are fixed to the two short sides at the bottom of the connecting rod 4, a flexible patch 402 is fixed to the side of the baffle 401 close to the top center of the workbench 1, and the photoelectric switch 105 is arranged on the side of the flexible patch 402 away from the baffle 401, and is arranged at the lower edge of the side of the flexible patch 402 away from the baffle 401. The connecting rod 4 cooperates with the baffle 401 to limit the position of the display screen transported by the belt conveyor 104, and protects the edge of the display screen through the flexible patch 402.

[0026] Furthermore, a lifting plate 301 is fixed to the telescopic end of the electric push rod 3, and the baffle 401 extends out of the top edge of the workbench 1. The bottom surface of the baffle 401 extending out of the top edge of the workbench 1 is fixed on the top of the lifting plate 301. The electric push rod 3 drives the lifting plate 301 to rise and fall, thereby driving the baffle 401 to rise and fall.

[0027] The operation process of this embodiment is as follows: during operation, the electric push rod 3 is started to drive the lifting plate 301 to descend until the baffle 401 is supported on the top of the workbench 1. At this time, the workbench 1 rotates the guide roller 102 and connects it above the workbench 1 through the rotating column 101. When the two guide rollers 102 are working, the edges of the two long sides of the display screen are guided and stuck by the guide rollers 102. At the same time, the display screen is guided to the belt conveyor 104 by the guide rollers 102, and is conveyed by the belt conveyor 104 until the display screen covers the photoelectric switch 105, and it is determined that the display screen is restricted in place. At this time, the belt conveyor 104 stops working, and the display screen is restricted in a suitable position by the flexible patch 402. After the belt conveyor 104 is restarted, the electric push rod 3 is started at the same time, driving the lifting plate 301 to drive the baffle 401 to rise above the display screen conveyed on the belt conveyor 104, so that after the display screen is glued, it is smoothly conveyed to the next work process on the belt conveyor 104. Specific embodiment three

[0028] See also Figure 1 , 6 , 7, 8, 9, on the basis of the specific embodiment 1, lifting blocks 503 are fixed at both ends of the moving track 602, a fixing sleeve 5 is arranged on the top of the lifting block 503, a hydraulic cylinder 2 501 is arranged on the upper part of the fixing sleeve 5, a hydraulic rod 2 502 is movably connected in the hydraulic cylinder 2 501, the bottom end of the hydraulic rod 2 502 is fixed to the top of the lifting block 503, and a limiting strip 603 is fixed on the top of the moving track 602 on the side of the top center of the workbench 1 away from the electric hoist 6. When the moving track 602 is working, the hydraulic cylinder 2 501 connected by the fixing sleeve 5 drives the hydraulic rod 2 502 to rise and fall, and drives the lifting block 503 to rise and fall. The lifting of the lifting block 503 drives the moving track 602 to rise and fall, and the working range of the electric hoist 6 is limited by the limiting strip 603.

[0029] Specifically, a connecting block 601 is fixed at the center of the bottom of the electric hoist 6, and an exhaust nozzle 7 and a glue removal nozzle 8 are respectively fixed at the two edges of the bottom of the connecting block 601 parallel to the short sides of the top of the workbench 1. The electric hoist 6 is connected to the exhaust nozzle 7 and the glue removal nozzle 8 via the connecting block 601.

[0030] Furthermore, the glue removal nozzle 8 is arranged at the edge of the bottom of the connecting block 601 near the top center of the workbench 1, one end of the exhaust nozzle 7 is fixedly connected to an air supply pipe 701, and one end of the glue removal nozzle 8 is fixedly connected to a glue supply pipe 801. The end of the air supply pipe 701 away from the exhaust nozzle 7 is connected to a pipeline for conveying high-pressure air, and the end of the glue supply pipe 801 away from the glue removal nozzle 8 is connected to a pipeline for conveying glue. Electric control valves 702 are fixed in the middle of the air supply pipe 701 and the glue supply pipe 801. During operation, when the electric hoist 6 is driven to descend, the two electric control valves 702 are started. When the two electric control valves 702 are started, the glue is conveyed to the glue removal nozzle 8 through the rubber pipe to apply glue to the display screen, and the decompressed air ejected from the exhaust nozzle 7 blows the surface of the glue to make it flat.

[0031] The operation process of this embodiment is as follows: during operation, after the display screen is lifted above the connecting rod 4, the hydraulic cylinder 2 501 in the fixing sleeve 5 is started, and the hydraulic cylinder 2 501 drives the hydraulic rod 2 502 to descend, driving the lifting block 503 to descend, driving the moving track 602 and the electric hoist 6 to descend, until the bottom of the glue discharge nozzle 8 contacts the surface of the display screen where glue is needed, and at the same time, the electric hoist 6 is started to drive the glue discharge nozzle 8 to move, so that the surface of the display screen is coated with glue, until it moves away from the display screen, and at the same time, high-pressure air is transported to the exhaust nozzle 7 through the air pipe 701 to reduce pressure, and the decompressed air sprayed from the exhaust nozzle 7 blows the surface of the glue to flatten the surface of the glue, so that the surface of the glue is smoother, and after completion, the two electric control valves 702 are closed, and the hydraulic cylinder 2 501 in the fixing sleeve 5 is started, and the hydraulic cylinder 2 501 drives the hydraulic rod 2 502 to rise, driving the lifting block 503 and the moving track 602 to rise, and the electric hoist 6 is restarted to move in the reverse direction until it contacts the limit strip 603 and is restricted.
