[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0021] Example 1: Please refer to Figure 1 - Figure 9 , The display module full-lamination assembly device includes two symmetrically arranged bases 01. A rotating component is located in the middle of each base 01, and multiple execution boxes 11 are connected to the rotating component. The rotating component can be driven by the outside to achieve uniform rotation, thereby driving the execution boxes 11 to perform periodic circular motion. An operating mechanism is provided on the execution box 11. The operating mechanism operates and processes the internal CG, SCA, sensor, OCA adhesive, and OC, etc. A transfer box 03 is arranged between the execution boxes 11 on the two bases 01. A transfer mechanism is provided in the transfer box 03. A guide frame 06 is provided on one side of one of the bases 01, and a conveyor belt 05 is provided in the guide frame 06. The transfer mechanism in the transfer box 03 can transfer raw materials to meet different production operation needs. Finally, the finished product falls onto the conveyor belt 05 for transfer. A workstation is provided on one side of the conveyor belt 05, where workers can be added for manual sorting or other installation work.
[0022] The rotating assembly includes a rotating ring 04 rotatably connected to the base 01. The outer side of the rotating ring 04 is toothed, allowing it to connect two rotating rings 04 with a belt. The belt is then driven by an existing mechanism to make the two rotating rings 04 rotate synchronously. Alternatively, a stepper motor can be used to control the rotation of each rotating ring 04 individually. Multiple bidirectional air guide tubes 13 are fixedly connected to the rotating ring 04. One end of each bidirectional air guide tube 13 is connected to a diverter 31 located on the central axis of the base 01. One end of the diverter 31 is connected to a circulation pump 02. Multiple induction heads 15 corresponding to the transfer box 03 are fixedly connected to the outer wall of the circulation pump 02. 4 is fixedly connected to multiple support pipes 18 connected to the execution box 11. The rotation of the rotating ring 04 drives the bidirectional air guide pipe 13 and the execution box 11 to rotate synchronously, forming a circulation. At the same time, the circulation pump 02 works. Through the flow divider 31, the bidirectional air guide pipe 13, the rotating ring 04 and the support pipes 18, some of the execution boxes 11 are filled with gas and some of the execution boxes 11 are evacuated to meet the requirements of the surrounding environment in the corresponding process. The bidirectional air guide pipe 13 is an existing mechanism, which is a combination of multiple sets of pipes and corresponding solenoid valves. The pipes are connected to the input end and the output end of the circulation pump 02 respectively to form a controllable fluid conduction channel.
[0023] The implementation principle of this application embodiment is as follows: During operation, the CG and sensor are placed in the execution box 11 on the side away from the guide frame 06. At the same time, SCA glue is added to the colloid cylinder 07 on the execution box 11. Then, the operation mechanism is used to squeeze and bond them. Simultaneously, the rotating mechanism transports the raw material of the semi-finished product to the transfer box 03 and then transfers it to the execution box 11 on the other side through the transfer mechanism. Before this, the execution box 11 on the other side has OC adsorbed and placed on it. Then, the operation mechanism is used to squeeze and bond it again. At the same time, the rotating mechanism transports the raw material of the finished product to the top of the transport belt 05. Then, the product is transported through the transport belt 05 for subsequent transportation and subsequent installation or inspection is carried out manually.
[0024] Example 2: Combination Figure 1 - Figure 7 This embodiment is an improvement on embodiment 1, further described in the following aspects: The transfer mechanism includes a transparent strip 21 located inside the transfer box 03. The transparent strip 21 is made of transparent material and contains an ultraviolet lamp 22. An ultraviolet lamp 23, which is fixedly connected to the transfer box 03, is installed on the top of the transparent strip 21. Through the operation of the operating mechanism, the raw material on the operating mechanism can fall into the transparent strip 21 due to inertia and gravity. Then, through the transport of the transparent strip 21, it enters the operating mechanism on the other side by gravity and inertia, completing the transfer. During the transfer process, the ultraviolet lamp 23 and the ultraviolet lamp 22 work synchronously to generate ultraviolet light, thereby performing UV curing.
[0025] A filter box 26 is also fixedly connected to the outside of the transfer box 03. A functional pump 27 is connected to one side of the filter box 26, and an auxiliary pipe 20 extending into the transfer box 03 is connected to the other side of the filter box 26. The functional pump 27 can generate protective gas, which is then filtered by the filter box 26 and enters the transfer box 03 through the auxiliary pipe 20, thereby protecting the raw materials processed in the transfer box 03 to a certain extent and reducing the scrap rate of the finished product.
[0026] The implementation principle of this application embodiment is as follows: During operation, the pasted semi-finished product is tilted and ejected onto the transparent strip 21 by the moving plate 33. Then, it is transported by the transparent strip 21. During the transportation process of the transparent strip 21, it enters the operating mechanism on the other side by gravity and inertia to complete the transfer. During the transfer process, the second ultraviolet lamp 23 and the first ultraviolet lamp 22 work synchronously to generate ultraviolet light, thereby performing UV curing.
[0027] Example 3: Combination Figure 1 - Figure 9 This embodiment is an improvement on embodiment 1, further described in the following aspects: The operating mechanism includes multiple electric slide rails 25 installed inside the execution box 11. The moving ends of two electric slide rails 25 located at the top and bottom positions are respectively connected to a hollow plate 08 and a bottom support box 09. Driven by the electric slide rails 25, the hollow plate 08 and the bottom support box 09 can move along the trajectory of the electric slide rails 25, eventually moving outside the execution box 11, thus receiving raw materials or discharging materials. Multiple suction nozzles 32 are connected to the bottom of the hollow plate 08, and a flexible hose connected to a support pipe 18 is connected to one side of the hollow plate 08. The flexible hose is connected to the support pipe 18 and can perform air extraction, thereby creating negative pressure at the suction nozzles 32 to suck up raw materials. Simultaneously, a solenoid valve is connected to the flexible hose to control the opening and closing of the pipeline. The bottom tray 09 is connected to a placement component, which places the corresponding raw materials to ensure subsequent bonding. A sealing door 12 is provided below the bottom tray 09 and is rotatably connected to the execution box 11. An electromagnet 34 is provided inside the sealing door 12. A spraying component is also provided inside the execution box 11 for spraying the adhesive onto the module. A pressing component is also connected to the bottom of the execution box 11. The placement component is used for placing the raw materials and limiting the bonding of multiple raw materials. The electromagnet 34 generates magnetism, which can drive the two permanent magnets 35 at the bottom of the moving plate 33 to move. The permanent magnets 35 on both sides receive different strengths of magnetic force, which causes the two ends of the moving plate 33 to move differently, thereby further tilting and realizing the subsequent material discharge.
[0028] The placement component includes a movable plate 33 located inside the base tray 09. The movable plate 33 is slidably connected to the base tray 09. A trapezoidal groove is provided on the base tray 09. The movable plate 33 is located in the trapezoidal groove. A spring that is fixedly connected to the base tray 09 is fixedly connected to one side of the movable plate 33. Multiple permanent magnets 35 are connected to the bottom of the movable plate 33. The trapezoidal groove guides the movable plate 33. Through the elastic force of the spring, the movable plate 33 returns to the designated position along the groove wall of the trapezoidal groove.
[0029] The spraying assembly includes a colloid cylinder 07 threadedly connected to the execution box 11. A pressure pump 14 is connected to the top of the colloid cylinder 07, and a second hose 38 is connected to the bottom of the colloid cylinder 07. The other end of the second hose 38 is connected to a symmetrically arranged main pipe 16. An electric slide rail 28 is also connected inside the execution box 11. A moving block is connected to the moving end of the electric slide rail 28. The main pipe 16 is fixedly connected to the moving block. An auxiliary plate 37 is fixedly connected between the two main pipes 16. Multiple spray nozzles 36 are connected to the bottom of the main pipe 16. The colloid cylinder 07 stores colloid raw materials. At the same time, a heating element is also provided inside the colloid cylinder 07 to maintain a constant temperature of the colloid and ensure its fluidity. The pressure pump 14 pressurizes the colloid cylinder 07, so that the colloid in the colloid cylinder 07 enters the main pipe 16 through the second hose 38 and is finally sprayed out through the spray nozzles 36 to complete the addition of colloid. Multiple spray nozzles 36 on both sides spray simultaneously to ensure the stability and uniformity of the colloid spraying.
[0030] The auxiliary plate 37 has an installation groove on one side, and a scraper is installed in the installation groove. The scraper can be installed in the installation groove as needed, and the scraper can scrape the sprayed adhesive to ensure the uniformity of the adhesive.
[0031] The pressing assembly includes a telescopic rod 19 fixedly connected to the actuator box 11. A push plate 17 is fixedly connected to the moving end of the telescopic rod 19. The bottom of the base box 09 is provided with a through hole for the push plate 17 to pass through. A heating wire is provided inside the push plate 17. The movement of the telescopic rod 19 can drive the push plate 17 to move through its moving end. The push plate 17 contacts the moving plate 33 through the through hole, and then forces the moving plate 33 to move and contact and squeeze the suction nozzle 32, thereby achieving pressure bonding. The heating wire on the push plate 17 is heated to ensure the quality of the product.
[0032] The implementation principle of this application embodiment is as follows: After feeding, the raw material on one side is adsorbed onto the suction nozzle 32, and one raw material is placed on the moving plate 33. Then, driven by the electric slide rail 25, it reaches the middle of the execution box 11. At this time, the electric slide rail 28 drives the main pipe 16 and the spray nozzle 36 to move, and the pressure pump 14 pressurizes the colloid cylinder 07, so that the colloid is spread onto the surface of the raw material through the spray nozzle 36. After spraying, the spray nozzle 36 returns to its original position. At this time, the telescopic rod 19 drives the push plate 17 to pass through the bottom tray box 09, so that the moving plate 33 moves upward. And after the push plate 17 is heated, the temperature inside the entire execution box 11 is at a high temperature, so that the raw material on the moving plate 33 comes into contact with the raw material on the suction nozzle 32 and adheres to it. After a certain period of compression, the support tube 1 8. Reverse ventilation causes the material on the suction nozzle 32 to adhere to a piece located on the moving plate 33, and the continuous gas supply increases the pressure in the execution box 11, thereby defoaming. After rotating a certain angle, the sensor head 15 senses and, through the CNC system, the electric slide rail 25 is activated, which in turn pushes the corresponding hollow plate 08 and bottom tray 09 to move. The bottom tray 09 forces the sealing door 12 to open, and the electromagnet 34 is activated, causing the moving plate 33 to tilt rapidly. Under the action of inertia and gravity, the semi-finished product is transported through the transparent belt 21 to the next moving plate 33. After a similar operation, adhesion is achieved, and the finished product finally falls onto the conveyor belt 05, thereby realizing the discharge. At the same time, subsequent installation or inspection work can be carried out on the conveyor belt 05.
