Description

Technical Field

[0001] This utility model belongs to the technical field of LCD dispensing machines, specifically an automatic dispensing machine for LCD panels. Background Technology

[0002] Automatic LCD panel dispensing machines are indispensable and crucial automated equipment in modern LCD manufacturing, especially in the module assembly stage. Utilizing high-precision motion control, visual positioning, and precision dispensing technology, they achieve rapid, stable, and consistent adhesive application on LCD panels, primarily for bonding and sealing to meet the stringent requirements of structural strength, sealing protection, and long-term reliability. Automatic LCD panel dispensing machines include raw material mixing equipment, polyurethane coating equipment, drying and curing equipment, laminating equipment, and release liner peeling equipment.

[0003] In existing technologies, when applying adhesive to an LCD panel using a dispensing machine, the panel is aligned using a CCD to determine the dispensing position. The LCD panel is then placed on a dispensing platform, and the dispensing machine applies adhesive to the designated area of ​​the panel. However, some LCDs are small, and when placed on the dispensing platform, the adhesive can easily drip onto the platform surface. Since there are no cleaning components on the platform surface, the next time an LCD panel is placed, it can easily cause the panel to be placed unevenly, affecting the accuracy of coating the next LCD panel.

[0004] Therefore, a device is needed to ensure the cleanliness of the dispensing platform. Utility Model Content

[0005] Based on this, this solution provides an automatic dispensing machine for LCD panels. By setting a cleaning scraper on the dispensing platform, the glue dripping on the placed components can be cleaned up, ensuring the flatness of the dispensing platform and making the next panel placed flat, which is conducive to improving the accuracy of subsequent coating.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] An automatic dispensing machine for LCD panels includes: a bracket and a silver paste adhesive dispensing machine and a line adhesive dispensing machine mounted on the bracket. Both the silver paste adhesive dispensing machine and the line adhesive dispensing machine are equipped with a placement mechanism. The placement mechanism includes guide rails, with slide blocks slidably connected to two guide rails. A fixing plate is fixedly connected to each of the two slide blocks. Two sets of bearing seats are welded opposite each other to the two fixing plates. A drive shaft is rotatably connected between the two bearing seats on the same side. A placement conveyor belt is wound around the two drive shafts. Two side plates are fixedly connected opposite each other to the fixing plates. A scraper that abuts against the placement conveyor belt is held between the two side plates. Sliding strips are welded to both sides of the scraper. A sliding shell is fixedly connected to each of the two side plates. The sliding strips are slidably connected inside the sliding shells. A screw is threaded to the end of the sliding shell, and the screw is rotatably connected to the sliding strip. Two side frames are fixedly connected opposite each other to the fixing plates. A support plate that abuts against the placement conveyor belt is fixedly connected between the two side frames by screws.

[0008] Optionally, in one embodiment of the present invention, the placement mechanism further includes a collection hopper. Both the silver paste adhesive dispensing machine and the line adhesive dispensing machine are provided with a collection hopper located at the bottom of the scraper. The scraper is inclined and the end of the scraper has an arc-shaped structure.

[0009] Optionally, in one embodiment of the present invention, the placement mechanism further includes a third motor, wherein a third motor is mounted on one of the bearing seats, and the output end of the third motor is fixedly connected to one of the drive shafts via a coupling.

[0010] Optionally, in one embodiment of the present invention, the placement mechanism further includes two rotating shafts. The inner tops of the silver paste adhesive dispensing machine and the line adhesive dispensing machine are rotatably connected to rotating shafts that pass through guide rails. A belt is wound between the two rotating shafts in the same group. A second motor is installed inside the silver paste adhesive dispensing machine and the line adhesive dispensing machine. The output end of the second motor is connected to the rotating shaft through a coupling.

[0011] Optionally, in one embodiment of the present invention, a feeding conveyor belt and a discharging conveyor belt are installed on the support, and the feeding conveyor belt and the discharging conveyor belt are diagonally distributed on both sides of the support.

[0012] Optionally, in one embodiment of the present invention, a CCD alignment component is installed on the bracket, and the CCD alignment component is located on one side of the feeding conveyor belt.

[0013] Optionally, in one embodiment of the present invention, a conveying mechanism is installed on the bracket, the conveying mechanism includes a slide rail, the slide rail is installed on the bracket, a first motor is installed at the end of the slide rail, a lead screw is rotatably connected inside the slide rail, the lead screw is connected to the output end of the first motor through a coupling, a slide frame is threadedly connected to the lead screw and slidably connected to the slide rail, and a vacuum suction cup is fixedly connected to the slide frame.

[0014] Optionally, in one embodiment of the present invention, a wire adhesive cleaning tank is installed on the bracket, and a surface adhesive silver paste cleaning tank is installed on the bracket.

[0015] Optionally, in one embodiment of the present invention, a transfer platform is installed on the support, and a drying mechanism and a material handling arm are installed on the support.

[0016] Compared with the prior art, the automatic dispensing machine for LCD panels provided by this utility model has the following characteristics:

[0017] During or after the dispensing process, glue drips from the dispensing component onto the placement conveyor belt. At this time, the third motor on the bearing housing can be activated to drive the shaft to rotate, which in turn drives the placement conveyor belt to rotate. Because the scraper, which is inclined between the two sliding housings, abuts against the placement conveyor belt, the scraper automatically cleans the glue adhering to the surface of the placement conveyor belt as it rotates, improving the flatness of the placement conveyor belt and facilitating the flat placement of the next LCD panel. This prevents dispensing deviation and improves dispensing accuracy. During dispensing, the support plate between the two side frames can support the LCD panel, and the slider can be tilted and moved by rotating the screw to adjust the tension of the scraper. The cleaned glue falls into the collection hopper for collection. Since the slide can move on the guide rail, the length of the collection hopper is greater than the length of the guide rail, allowing the glue on the placement conveyor belt to be cleaned from any position.

[0032] Example 1

[0033] Because existing dispensing platforms are prone to adhesive buildup, and failure to clean them promptly can affect subsequent processing, an automatic dispensing machine for LCD panels was designed to keep the dispensing platform clean. The specific solution is as follows:

[0034] like Figure 1-10 As shown, an automatic dispensing machine for LCD panels includes a bracket 1 and a silver paste adhesive dispensing machine 6 and a line adhesive dispensing machine 7 mounted on the bracket 1. Both the silver paste adhesive dispensing machine 6 and the line adhesive dispensing machine 7 are equipped with a placement mechanism 11. The placement mechanism 11 includes guide rails 1101, with slide blocks 1105 slidably connected to each guide rail 1101. Each slide block 1105 is fixedly connected to a fixing plate 1102. Two sets of bearing seats 1113 are welded to each fixing plate 1102. A drive shaft 1114 is rotatably connected between the two bearing seats 1113 on the same side. A placement conveyor belt 1103 is wound around the two drive shafts 1114. The fixing plate 1101... 2. Two side plates 1118 are fixedly connected to each other. A scraper 1110 that abuts against the conveyor belt 1103 is held between the two side plates 1118. Sliding strips 1115 are welded to both sides of the scraper 1110. Sliding housings 1116 are fixedly connected to both side plates 1118. The sliding strips 1115 are slidably connected to the inside of the sliding housings 1116. A screw 1117 is threaded to the end of the sliding housings 1116. The screw 1117 is rotatably connected to the sliding strips 1115. Two side frames 1111 are fixedly connected to each other on the fixed plate 1102. A support plate 1109 that abuts against the conveyor belt 1103 is fixedly connected between the two side frames 1111 by screws.

[0035] The placement mechanism 11 also includes a collection hopper 1104. Both the silver paste adhesive dispensing machine 6 and the line adhesive dispensing machine 7 are equipped with a collection hopper 1104 located at the bottom of the scraper 1110. The scraper 1110 is inclined and the end of the scraper 1110 has an arc-shaped structure, so as to collect the adhesive adhering to the placement conveyor belt 1103 that is cleaned by the scraper 1110.

[0036] The placement mechanism 11 also includes a third motor 1112. The third motor 1112 is mounted on one of the bearing seats 1113. The output end of the third motor 1112 is fixedly connected to one of the drive shafts 1114 through a coupling, so that the third motor 1112 drives the drive shaft 1114 to rotate and automatically drive the placement conveyor belt 1103 to rotate, thereby achieving the purpose of automatically cleaning the adhesive on the placement conveyor belt 1103.

[0037] The placement mechanism 11 also includes two rotating shafts 1107. The inner tops of the silver paste adhesive dispensing machine 6 and the line adhesive dispensing machine 7 are rotatably connected to the rotating shafts 1107 that pass through the guide rail 1101. A belt 1106 is wound between the two rotating shafts 1107 in the same group. A second motor 1108 is installed inside the silver paste adhesive dispensing machine 6 and the line adhesive dispensing machine 7. The output end of the second motor 1108 is connected to the rotating shaft 1107 through a coupling. When the second motor 1108 is started, the belt 1106 drives the slide 1105 to rotate, thereby enabling the slide 1105 to drive the fixed plate 1102 to move on the guide rail 1101 and dispense adhesive at different positions.

[0038] A feeding conveyor belt 2 and a discharging conveyor belt 13 are installed on the support frame 1, arranged diagonally on both sides of the support frame 1. A CCD alignment component 3 is installed on the support frame 1, located on one side of the feeding conveyor belt 2. The feeding belt is responsible for transporting the workpieces to be processed into the equipment. The CCD alignment component 3 corrects the position and orientation of the panel to ensure that the workpiece is in an accurate position during subsequent processing. A transfer platform 9, a drying mechanism 10, and a discharging and handling hand 12 are installed on the support frame 1. The CCD charge-coupled device camera performs visual inspection and alignment of the workpiece. Through image recognition technology, the position on the workpiece that needs to be glued is accurately determined, and the position information is fed back to the control system for subsequent processing. The dispensing mechanism can operate accurately at designated positions, ensuring the precision and quality of dispensing. The unloading conveyor belt 13 and the unloading handler 12 transport the panels that have completed all processing steps and dried them from the equipment and place them at the designated unloading position for subsequent packaging, inspection or other production stages. The transfer platform 9 serves as a temporary storage and transition area for the panels between various processing stages, acting as a buffer and coordinating the processing rhythm of different workstations to ensure the smooth progress of the production process. The drying mechanism 10 can dry the panels that need to be dispensed with glue. By controlling appropriate temperature, humidity and ventilation conditions, the glue can be cured quickly and evenly to achieve the required bonding, sealing or conductivity properties, completing the final step of the entire dispensing process.

[0039] A conveying mechanism 5 is installed on the bracket 1. The conveying mechanism 5 includes a slide rail 501. The slide rail 501 is installed on the bracket 1. A first motor 502 is installed at the end of the slide rail 501. A lead screw 504 is rotatably connected inside the slide rail 501. The lead screw 504 is connected to the output end of the first motor 502 through a coupling. A slide frame 505 is threadedly connected to the lead screw 504 and slidably connected to the slide rail 501. A vacuum suction cup 503 is fixedly connected to the slide frame 505. The vacuum suction cup 503 mechanism on the bracket 1 is responsible for moving the workpiece from one station to another. For example, it moves the aligned panel to the dispensing station to ensure the smooth transfer of the workpiece between each processing stage and improve the continuity of the production process.

[0040] The bracket 1 is equipped with a wire adhesive cleaning tank 4 and a surface adhesive / silver paste cleaning tank 8. Before dispensing, the components related to the adhesive used for sealing or connecting are cleaned to remove any impurities or residual adhesive, ensuring the purity of the wire adhesive and a smooth dispensing process. This avoids problems such as dispensing blockage or poor dispensing quality caused by impurities. After the dispensing operation is completed, the areas that may be contaminated by the surface adhesive and silver paste are cleaned to remove excess adhesive or contaminants in a timely manner, preventing adhesive residue from affecting subsequent process steps or product quality, while maintaining a clean working environment for the equipment.

[0041] Working principle:

[0042] Before dispensing, the LCD panel is placed on the feeding conveyor belt 2 for transport. The feeding belt transports the workpiece to be processed into the equipment. The CCD alignment component 3 corrects the position and orientation of the panel to ensure that the workpiece is in the correct position during subsequent processing. During transport, the workpiece is visually inspected and aligned by the CCD camera after passing through the CCD alignment component 3. Through image recognition, the position on the workpiece that needs to be dispensed is accurately determined, and the position information is fed back to the control system so that the subsequent dispensing mechanism can operate accurately at the designated position, ensuring the accuracy and quality of dispensing.

[0043] Before dispensing, the relevant components of the line adhesive are cleaned. During cleaning, the line adhesive cleaning tank 4 can be cleaned to remove any impurities, residual adhesive, etc., to ensure the purity of the line adhesive and the smoothness of the dispensing process, and to avoid problems such as dispensing blockage or poor dispensing quality caused by impurities.

[0044] After the cleaning of the components related to the line adhesive is completed, the aligned LCD panel is transported to the placement conveyor belt 1103 on the silver paste top adhesive dispensing machine 6 or the line adhesive dispensing machine 7 via vacuum suction cup 503 for adhesive application. After the dispensing operation is completed, areas that may be contaminated by top adhesive and silver paste are cleaned to remove excess glue or contaminants in a timely manner, preventing glue residue from affecting subsequent process steps or product quality. At the same time, the working environment of the equipment is kept clean. Then, the LCD panel is transferred to the transfer platform 9 via vacuum suction cup 503. The transfer platform 9 serves as a temporary transfer point for the panel between various processing stages. The storage and transition area serves as a buffer, coordinating the processing rhythm of different workstations and ensuring the smooth progress of the production process. After transfer, the first motor 502 drives the lead screw 504 to rotate, changing the position of the slide 505 on the slide rail 501, and then placing the LCD panel on the drying mechanism 10 for drying. The panel after dispensing needs to be dried in the drying mechanism 10. By controlling the appropriate temperature, humidity and ventilation conditions, the glue can be cured quickly and evenly to achieve the required bonding, sealing or conductivity properties, completing the final step of the entire dispensing process.

[0045] After drying, the unloading conveyor belt 13 and the unloading handler 12 will remove the panels that have completed all processing steps and dried from the equipment and place them at the designated unloading position for subsequent packaging, testing or other production processes.

[0046] Finally, during the dispensing process, since the LCD panel is placed on the placement conveyor belt 1103 of the line glue dispensing machine 7 and the silver paste adhesive dispensing machine 6 for dispensing, adhesive will drip onto the placement conveyor belt 1103 during or after the dispensing process. At this time, the third motor 1112 on the bearing housing 1113 can be activated to drive the shaft 1114 to rotate, further enabling the drive shaft 1114 to drive the placement conveyor belt 1103 to rotate. Since the scraper 1110, which is inclined between the two sliding housings 1116, abuts against the placement conveyor belt 1103, the scraper 1110 automatically cleans the adhesive adhering to the surface of the placement conveyor belt 1103 when the placement conveyor belt 1103 rotates. Improving the flatness of the conveyor belt 1103 facilitates the flat placement of the subsequent LCD panel, avoids glue misalignment, and improves glue dispensing accuracy. During glue dispensing, the support plate 1109 between the two side frames 1111 can support the LCD panel. Alternatively, the slider 1115 can be rotated by rotating the screw 1117 to drive the scraper 1110 to tilt and move. Adjusting the tension of the scraper 1110 allows the cleaned glue to fall into the collection hopper 1104 for collection. The second motor 1108 can drive the slide 1105 to move on the guide rail 1101. Since the length of the collection hopper 1104 is greater than the length of the guide rail 1101, the glue on the conveyor belt 1103 can be cleaned from any position.

[0047] The automatic dispensing machine in this solution integrates a feeding conveyor belt 2, a CCD alignment component 3, a handling mechanism, a transfer platform 9, a drying mechanism 10, a material unloading and handling hand 12, and a material unloading conveyor belt 13. It is highly automated, reduces manual operation, improves production efficiency and consistency, and reduces human error.

[0048] The third motor 1112 drives the drive shaft 1114, which in turn rotates the placement conveyor belt 1103. An inclined scraper 1110 with an arc-shaped end makes close contact with the surface of the placement conveyor belt 1103, automatically scraping away any residual adhesive as the belt rotates. This prevents the accumulation of adhesive and ensures that the surface of the placement conveyor belt 1103 remains uneven, guaranteeing that the subsequently placed LCD panels are always in a level and stable state. A flat placement surface directly avoids problems such as adhesive misalignment, overflow, or uneven adhesive volume caused by uneven platforms, improving adhesive quality and product consistency.

[0049] The scraper 1110 slides within the sliding housing 1116 via its two sides 1115, and its end is adjusted by a screw 1117. The screw 1117 rotates to push the 1115, thereby precisely adjusting the pressure and position of the scraper 1110 relative to the conveyor belt 1103. The contact pressure and angle of the scraper 1110 can be flexibly adjusted according to the adhesive properties and cleaning effect requirements to ensure optimal scraping results. This also facilitates the replacement of worn scrapers 1110 or fine-tuning according to working conditions.

[0050] A collection hopper is installed directly below the scraper 1110. The scraped colloid falls directly into the hopper for centralized collection, facilitating subsequent cleaning and recycling.

[0051] The second motor 1108 drives the belt 1106, which in turn moves the slide 1105 on the guide rail, thereby changing the position of the entire placement mechanism 11 relative to the dispensing head. This allows for precise positioning of the dispensing area without the need to change fixtures or make significant adjustments to the equipment.

[0052] Example 2

[0053] In this embodiment, the structure of the automatic dispensing machine is basically the same as that of Embodiment 1. The difference is that a simple visual inspection station is integrated on the transfer platform 9. This inspection station also uses a CCD camera to detect the state of the LCD panel after dispensing, detect defects in advance, and prevent defective products from entering the drying platform.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
