Description

Technical Field

[0001] The invention belongs to the technical field of display screen gluing, and in particular refers to an automatic gluing robot for display panels. Background Art

[0002] Display panels are widely used in modern electronic products. With the growing market demand for thin, light and flexible electronic products, the production scale of thin display panels continues to expand, and the requirements for their production efficiency and yield rate are getting higher and higher. In the production process of thin display panels, the gluing process is a crucial link, which directly affects the reliability and service life of the product. There are two main types of traditional automated gluing equipment: one is a device that uses a roll of tape for continuous rolling and bonding, and the other is a device that uses negative pressure adsorption of the tape to directly press down and bond. However, neither of these two devices is suitable for the gluing process of display panels with cables.

[0003] Thin and light display panels are mostly flexible panels, usually composed of a display area, a substrate, and a cable connected to an external circuit. In order to minimize the panel thickness and save space, the cable is usually designed to extend along the edge of the panel, lie flat on the back of the screen, and finally extend from the edge of the panel. Although this design saves shipping space, it brings challenges to the subsequent gluing process. Due to the presence of the cable, the tape at the frame needs to be designed into a special-shaped structure, that is, a notch is opened at the middle edge of the tape to accommodate the cable.

[0004] For the first type of rolling-type gluing equipment, since customized special-shaped tapes are required, rolls of tapes cannot be used for continuous lamination. For the second type of adsorption-type downward pressing lamination equipment, due to the presence of the cable, the adsorption head cannot directly press down the frame, because it will directly press the cable under the tape, and the tape cannot be accurately attached to the target position. In addition, prefabricated special-shaped tapes usually adopt a double-sided tape structure, that is, both sides of the tape are covered with release paper. Usually, the release paper on the panel laminating surface is easier to tear off. Before laminating to the edge of the panel, the bottom release paper needs to be torn off first. This is relatively easy to achieve in manual operation, but it is a considerable challenge for automated equipment.

[0005] Therefore, the current method of gluing display panels with cables mainly relies on manual operation. The operator needs to manually bend the cable first, then align the pre-cut special-shaped tape with the cable position, tear off the bottom release paper, and then carefully stick it on the edge of the panel. This manual operation method has many disadvantages, including slow manual operation speed and high labor costs, which increase the production cost of the product. Manual operation is easily affected by human factors, such as the operator's proficiency and fatigue state, which can easily cause defects such as tape offset, wrinkling, and poor consistency, thereby reducing the product yield. Summary of the invention

[0006] In view of the above situation, the present invention provides an automatic glue sticking robot for display panels, which obtains tapes through a positioning and stacking mechanism of prefabricated special-shaped tapes, and integrates functions such as automatic peeling of release paper, automatic lifting of cables and precise tape sticking.

[0014] Furthermore, the cable arrangement posture adjustment mechanism includes a first bracket, the first bracket is fixedly arranged on one side of the second mounting plate, a mounting rod is fixedly arranged on the first bracket, a track receiving seat is symmetrically fixedly arranged on one side of both ends of the mounting rod, and a second bracket is symmetrically fixedly arranged on the other side of both ends of the mounting rod, a swing arm is tightly arranged on the outer side of the track receiving seat, a limiting shaft is vertically fixedly arranged on the inner side of one end of the swing arm, the limiting shaft is vertically engaged and rotatably connected with the track receiving seat, a slideway is opened in the swing arm, a sliding rod is tightly engaged and slidably arranged in the slideway, the end of the sliding rod away from the limiting shaft extends out of the swing arm, the sliding direction of the sliding rod is parallel to the swing arm, and the first sliding column and the second sliding column are vertically fixedly arranged on both sides of the end of the sliding rod close to the limiting shaft. Two sliding posts, the first sliding post and the second sliding post always penetrate the swing arm during the sliding process, the surface of the track receiving seat is provided with a horizontal track and a curved track, the horizontal track is connected to the curved track, the horizontal track is horizontally arranged and vertically points to the conveying direction of the chain conveying mechanism, the curved track is concentrically arranged with the limit axis and has an arc of 90 degrees, the curved track is located below the horizontal track, the first sliding post is tightly slidably arranged in the horizontal track and the curved track, a telescopic cylinder is provided on the outside of the second bracket, the fixed part of the telescopic cylinder is rotatably connected to the second bracket, the output end of the telescopic cylinder is fixedly provided with an output seat, the output seat is rotatably connected to the second sliding post, and a lifting rod is fixedly provided between one end of the two sliding rods extending out of the swing arm.

[0015] Furthermore, the first ball screw and the second ball screw are driven by a servo motor to control the translation of the translation receiving seat and the slide table respectively. When the cylinder translates to the top of the rubber strip stacking feeding mechanism, the suction nozzles on the two edges can be driven by the cylinder to descend into the positioning cover close to the positioning cover. The width of the suction nozzle is the same as the width of the special-shaped rubber strip. During the descent of the suction nozzle in the positioning cover, the upper end of the positioning column can resist the horizontal lifting rod.

[0016] Furthermore, the suction nozzle passes through the positioning cover, the hollow roller and the track receiving seat in the process of translation toward the chain conveying mechanism. The translation stroke of the hollow roller is perpendicular to the translation stroke of the suction nozzle. The translation stroke end points of the hollow roller and the two proximity sensors are located on both sides of the edge suction nozzle. The bottom surface of the special-shaped rubber strip adsorbed by the suction nozzle is flush with the upper end of the hollow roller during translation. Two track receiving seats are located on both sides of the edge suction nozzle.

[0017] Furthermore, the first suction pipe and the second suction pipe are connected to a pressure gas transmission system. In the initial position, the hollow roller is located at one end of the translation stroke. The suction nozzle is translated to the hollow roller position and pauses when facing the hollow roller. After the hollow roller passes through the proximity sensor on the same side, the proximity sensor controls the second suction pipe to suck air. After the hollow roller passes through the suction nozzle and the proximity sensor on the other side, the proximity sensor controls the second suction pipe to blow air.

[0018] Furthermore, when the suction nozzle is located in the positioning cover, the distance sensor detects that the distance value is lower than a threshold value and controls the first suction tube to inhale air; when the suction nozzle is located above the cable frame of the display panel and moves downward, the distance sensor detects that the distance value is lower than a threshold value and controls the first suction tube to deflate air.

[0019] Furthermore, when the first sliding post is located at the closed end of the arc track, the lifting rod is located below the outer side of the display panel cable, and when the first sliding post slides in the arc track toward the horizontal track, the lifting rod will contact the display panel cable from below, and when the first sliding post just enters the horizontal track, the lifting rod lifts the display panel cable and is located above the root of the display panel cable, and when the first sliding post is located at the closed end of the horizontal track, the lifting rod pushes the display panel cable until it no longer blocks the display panel frame.

[0020] Furthermore, a rubber layer is provided at a portion where the middle surface of the lifting rod contacts the display panel cable to increase friction.

[0021] Furthermore, after the cable arrangement posture adjustment mechanism has completed adjusting the display panel cable arrangement position, the cylinder pushes the suction nozzle down, and then the cylinder pushes the suction nozzle up, and then the cable arrangement posture adjustment mechanism starts to reset.

[0022] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The rubber strip stacking and feeding mechanism adopts the method of positioning cover and positioning column to achieve accurate positioning when taking materials. The special-shaped rubber strips are stacked vertically in the positioning cover, and the edges are in close contact with the inner wall of the positioning cover. The middle edge has a reserved opening facing the chain conveyor mechanism, which ensures the accuracy of the rubber strip taking direction and position. At the same time, the bottom plate surface is arrayed with positioning columns along the length direction. The side close to the positioning cover is in close contact with the special-shaped rubber strip, which effectively prevents the rubber strip from shifting or tilting during the stacking and suction process, and ensures that the rubber strip suction and release assembly can accurately suck the top layer of rubber strips every time.

[0023] (2) The rubber strip suction and release component realizes the suction judgment and pressing force control of the special-shaped rubber strip through the compression spring and distance sensor. During the descent of the suction nozzle, the distance sensor can monitor the distance between the fixed seat and the buffer seat. When the distance value is lower than the threshold, it indicates that the pressure applied to the special-shaped rubber strip reaches the preset value. By controlling the first suction tube to suction, the rubber strip is sucked. By controlling the first suction tube to deflate, the rubber strip is released and the bonding action is completed, thus realizing precise adsorption and bonding.

[0024] (3) The automatic peeling mechanism of the release paper realizes the automatic peeling of the release paper through the cooperation of the hollow roller and the second suction tube. When the suction nozzle adsorbs the special-shaped rubber strip and passes over the hollow roller, the hollow roller moves along the length direction of the rubber strip and passes through the special-shaped rubber strip under the drive of the second ball screw. The strip holes on the surface of the hollow roller can firmly adsorb the release paper on the bottom of the special-shaped rubber strip under the suction force generated by the second suction tube. As the roller rotates, the release paper is completely peeled off and wound on the surface of the roller to avoid residue or tearing. After the peeling is completed, the proximity sensor controls the second suction tube to blow air to separate the release paper from the hollow roller, thereby realizing the automatic processing of the release paper.

[0025] (4) The cable posture adjustment mechanism drives the second slide column and the swing arm through the telescopic cylinder, so that the lifting rod lifts the cable from the bottom and pushes it to the inside of the frame, avoiding the problems of low efficiency, high cost and easy errors in traditional manual operation, and overcoming the defect that traditional robot operation cannot handle cable interference. Through precise motion control, the mechanism can adjust it to the appropriate position without damaging the cable, ensuring that the special-shaped adhesive strip is accurately attached to the target area, significantly improving the efficiency and quality of gluing, and ensuring product consistency.

The bottom surface of the special-shaped rubber strip 47 adsorbed by the suction nozzle 335 is flush with the upper end of the hollow roller 557 during translation, and the two track receiving seats 64 are located on both sides of the edge suction nozzle 335.

[0053] Among them, the first suction tube 336 and the second suction tube 552 are connected to a pressure gas transmission system. In the initial position, the hollow roller 557 is located at one end of the translation stroke. The suction nozzle 335 translates to the position of the hollow roller 557 and pauses when it is facing the hollow roller 557. After the hollow roller 557 passes through the proximity sensor 56 on the same side, the proximity sensor 56 controls the second suction tube 552 to suck air. After the hollow roller 557 passes through the suction nozzle 335 and the proximity sensor 56 on the other side, the proximity sensor 56 controls the second suction tube 552 to blow air.

[0054] Among them, when the suction nozzle 335 is located in the positioning cover 43, the distance sensor 337 detects that the distance value is lower than the threshold value, and the distance sensor 337 controls the first suction tube 336 to suck air; when the suction nozzle 335 is located above the cable frame of the display panel 8 and moves downward, the distance sensor 337 detects that the distance value is lower than the threshold value, and the distance sensor 337 controls the first suction tube 336 to deflate.

[0055] It is understandable that the above working conditions can be successfully achieved through specific structural dimension design and control of the control system.

[0056] Among them, when the first sliding column 662 is located at the closed end of the arc track 69, the lifting rod 661 is located below the outer side of the display panel 8 cable. When the first sliding column 662 slides toward the horizontal track 68 in the arc track 69, the lifting rod 661 will contact the display panel 8 cable from below. When the first sliding column 662 just enters the horizontal track 68, the lifting rod 661 lifts the display panel 8 cable and is located above the root of the display panel 8 cable. When the first sliding column 662 is located at the closed end of the horizontal track 68, the lifting rod 661 pushes the display panel 8 cable until it no longer blocks the frame of the display panel 8.

[0057] After the cable arrangement posture adjustment mechanism 6 has adjusted the cable arrangement position of the display panel 8, the cylinder 31 pushes the suction nozzle 335 downward, and then the cylinder 31 pushes the suction nozzle 335 upward, and then the cable arrangement posture adjustment mechanism 6 starts to reset.

[0058] When in use, the chain conveyor mechanism 7 conveys the display panel 8 that has been pasted with the remaining frames by other glue robots. The display panel 8 is positioned on the chain of the chain conveyor mechanism 7 and is stably conveyed. When the display panel 8 is conveyed to the position of this device, it stops. Then the transport translation mechanism 2 starts to operate. The servo motor drives the first ball screw 22 to drive the translation receiving seat 23 to translate. When it moves to the top of the glue strip stacking feeding mechanism 4, it stops. The servo motor is controlled by the motor drive unit and the programmable logic control unit to realize that the translation receiving seat 23 moves to a specific position and then stops, so as to control the stroke of the glue stripping mechanism 3. This is common knowledge in the field of motor control, and this technology is used for the control of the glue stripping mechanism 3 and the automatic release paper peeling mechanism 5. It will not be described in detail. The cylinder 31 pushes the horizontal lifting rod 32 and the glue strip suction and release assembly 33 to move downward, and then the suction nozzle 335 begins to enter the positioning cover 43. After the suction nozzle 335 sucks the shaped rubber strip 47, the cylinder 31 controls the suction nozzle 335 to move up to the initial height, and the tension spring 46 recovers to make the positioning column 44 move up, so that the remaining shaped rubber strips 47 are always restricted in the positioning cover 43.

[0059] Then, the transport translation mechanism 2 controls the suction nozzle 335 to move toward the chain plate conveying mechanism 7 and stops when it moves to the position of the hollow roller 557. At this time, the second ball screw 53 drives the slide 54 and the hollow roller 557 to start approaching the special-shaped rubber strip 47 along the length direction of the special-shaped rubber strip 47. When the proximity sensor 56 on this side senses that the rolling suction mechanism 55 passes through, the proximity sensor 56 controls the second suction pipe 552 to inhale. Then, the hollow roller 557 comes to the bottom of the special-shaped rubber strip 47 and contacts the special-shaped rubber strip 47. The suction force generated by the strip hole 558 will suck the release paper at the bottom of the special-shaped rubber strip 47, and the hollow roller 557 will roll on the bottom surface of the special-shaped rubber strip 47, thereby peeling off the release paper at the end of the special-shaped rubber strip 47 and winding it on the surface of the hollow roller 557, and the compression spring 334 will The thickening phenomenon of the shaped rubber strip 47 on the surface of the buffer hollow roller 557 is prevented, and the contact force between the hollow roller 557 and the bottom surface of the shaped rubber strip 47 becomes greater to ensure continuous rolling. When the shaped rubber strip 47 is produced, the bottom release paper is easier to tear off, thereby avoiding the separation of the release paper on the upper side of the shaped rubber strip 47. After the hollow roller 557 passes through the shaped rubber strip 47, it peels off and rolls up all the release paper, and after passing through the proximity sensor 56 on this side, the proximity sensor 56 controls the second suction pipe 552 to blow air, so that the strip hole 558 is blown and the release paper is restored, so that the release paper gets rid of the hollow roller 557 and falls into the storage device, thereby realizing the automatic peeling of the release paper, and the next time the hollow roller 557 moves in the opposite direction, it will repeat the above movement law to realize the next peeling of the release paper.

[0060] When the suction nozzle 335 continues to be located just above the frame of the display panel 8 to be glued, the telescopic cylinder 67 extends to drive the second slide post 663 to move, which will drive the swing arm 65 to rotate toward the display panel 8 with the limit shaft 652 as the axis, and the slide bar 66 and the lifting rod 661 make the same movement. Since the fixed part of the telescopic cylinder 67 is rotatably connected to the second bracket 63, the telescopic cylinder 67 itself can adjust the angle at will to adapt to the movement trajectory of the second slide post 663. Initially, the first slide post 662 is located at the closed end of the arc track 69. At this time, the lifting rod 661 is located below the outer side of the display panel 8 cable. During the sliding process of the first slide post 662 toward the horizontal track 68 in the arc track 69, the lifting rod 661 will contact the display panel 8 cable from below. When the first slide post 662 just enters the horizontal track 6 At 8 o'clock, the lifting rod 661 lifts the display panel 8 cable and is located above the root of the display panel 8 cable. As the telescopic cylinder 67 continues to extend, the first slide column 662 will slide in the horizontal track 68, causing the slide rod 66 to begin to extend outward, thereby driving the lifting rod 661 to push the display panel 8 cable to no longer block the display panel 8 frame. Then the cylinder 31 pushes the suction nozzle 335 down. When the display panel 8 frame is pressed down to a certain extent, the distance sensor 337 detects that the distance value is lower than the threshold, indicating that the special-shaped rubber strip 47 has been fully pressed down to fit the frame. The distance sensor 337 controls the first suction tube 336 to deflate. When the suction nozzle 335 moves up, it will not generate suction on the special-shaped rubber strip 47. The gluing work is completed, and the cable posture adjustment mechanism 6 is restored and waits for the next operation.
