Technical Field

[0001] The present invention relates to the technical field of display module assembly, and more specifically, to a flat display module laminating and assembling process and device. Background Art

[0002] The LCD flat panel display module includes a liquid crystal panel and a backlight assembly. The LCD panel is attached to the backlight assembly to complete the assembly of the LCD display module. During the assembly process, the LCD display panel is generally attached to the frame of the backlight module through glue. After the two are assembled, the backlight module provides the LCD display panel with uniform surface light.

[0003] The invention patent with patent announcement number CN114527590B discloses an assembly and bonding device for a liquid crystal display panel and a backlight module, including an assembly substrate, a conveying device arranged on the assembly substrate, a placing device placed on the conveying device, a gluing device arranged on the assembly substrate, and an adsorption clamping device arranged on the assembly substrate for adsorbing and conveying the liquid crystal display panel. The gluing device can adjust the length of the glue outlet according to the length of the backlight module frame, so that the length of the glue outlet is unified with the length of the frame, thereby improving the speed of glue application.

[0004] However, the invention still has the following problems: the glue coating device adjusts the length of the glue outlet through the coordination of multiple structures to perform the glue coating operation, has numerous structures and a complicated operation process; in addition, the glue liquid is directly released downward through the glue outlet, making it difficult to evenly apply the glue liquid on the frame of the backlight module, which easily causes glue overflow and has certain disadvantages.

[0005] Therefore, in view of the above problems, a flat display module lamination assembly process and device are proposed. Summary of the invention

[0006] The purpose of the present invention is to solve the existing problems. Compared with the existing technology, a flat display module bonding and assembly process and device are provided. A glue coating table with a pair of glue dipping tanks is set up and a glue coating tape immersed in the glue dipping tank is transmitted. The front and rear sides of the upper end of the glue coating table are installed with adjustment guide structures for guiding and positioning the upper ends of the two sides of the glue coating tape. According to the length of the backlight module frame, only the bidirectional screw needs to be rotated to adjust the length of the glue coating tape protruding horizontally upward by adjusting the spacing between a pair of positioning rollers, so that its length is compatible with the length of the backlight module frame to be glued. During operation, the transmitted glue coating tape is used to evenly transfer the glue liquid to the backlight module frame, which not only simplifies the gluing operation, but also effectively improves the gluing uniformity.

[0007] The purpose of the present invention can be achieved through the following technical solutions: a flat display module laminating and assembling device, comprising an assembly table and a conveying table and a delivery table installed at the left and right ends thereof, the delivery table is installed with a backlight module positioning table for conveying a backlight module, the front and rear directions of the delivery table are fixedly installed with a display module positioning table 1 and a display module positioning table 2 for positioning the display module, and the delivery table is also installed with a conveying structure for conveying the display module, the rear end of the assembly table is fixedly connected with a chain conveyor located above the conveying table and the delivery table, and a plurality of adsorption structures for adsorbing and transmitting the backlight module are distributed on the chain conveyor;

[0008] A gluing platform located between the transfer platform and the end of the conveying platform is fixed on the assembly platform, and a gluing tank is provided at the upper ends of both front and rear sides of the gluing platform. A gluing belt is installed inside the gluing tank through a pair of driving rollers arranged on the left and right sides, and an adjusting guide structure for guiding and positioning both sides of the upper end of the gluing belt is installed at the front and rear sides of the upper end of the gluing platform.

[0009] Furthermore, the backlight module positioning platform is a rectangular frame structure with an empty slot at the upper end. A positioning slot that is compatible with the backlight module and connected to the empty slot is opened at the upper end of the backlight module positioning platform. When positioning the backlight module, the technician places the backlight module on the backlight module positioning platform, and the left and right end walls of the backlight module fit into the positioning slot for easy positioning.

[0010] Furthermore, the display module positioning platform 1 and the display module positioning platform 2 are both provided with through grooves with upper and lower and left and right openings in the middle, and the left and right sides of the upper ends of the display module positioning platform 1 and the display module positioning platform 2 are respectively provided with inner card slot 1 and inner card slot 2 which are adapted to the display module and connected to the through groove, and the display module positioning platform 2 is also provided with an outer card slot which is connected to the inner card slot 2 and adapted to the backlight module.

[0011] Furthermore, the conveying structure includes an electric guide rail 1 and an electric guide rail 2 installed on both sides of the conveying platform, and the electric guide rail 1 and the electric guide rail 2 are both installed with a moving component that can move back and forth in a horizontal direction. The moving component includes a moving seat installed for horizontal sliding, and a lifting platform is fixedly installed on the moving seat through a pair of electric push rods 2.

[0012] Furthermore, the adsorption structure includes a connecting plate installed on the chain conveyor transmission structure, and a suction cup that can be extended and retracted in the vertical direction is installed on the connecting plate through an electric push rod. An adsorption box is installed at the outer end of the connecting plate, and a micro air pump connected to the suction cup is installed in the adsorption box.

[0013] Furthermore, the upper end of the glue coating platform is fixedly connected to a supporting plate whose upper end is arranged flush with the upper end surface of the glue coating tape. When the backlight module on the backlight module positioning platform is transferred to the glue coating platform by using the adsorption structure, the bottom end surface of the backlight module contacts the supporting plate, and the glue coating of the frame on both sides of the backlight module just contacts with the upper end surfaces of a pair of glue coating tapes.

[0014] Furthermore, the adjustment guide structure includes an operating box fixed on the glue coating table, a bidirectional screw is rotatably installed in the operating box, a handle or a driving motor is connected to the outer end of the bidirectional screw, and moving blocks are threadedly connected to the left and right ends of the bidirectional screw, and a positioning roller for guiding and positioning the glue coating tape is fixedly connected to the outer end of the moving block.

[0015] The present invention also provides a flat display module lamination assembly process, comprising the following steps:

[0016] Step 1: Backlight module loading process: the technician places the backlight module with the glue-coated surface facing downward on the backlight module positioning table, uses the conveyor table to convey the backlight module positioning table to the end of the chain conveyor, and then uses the adsorption structure on the chain conveyor to adsorb and clamp the backlight module;

[0017] Step 2: Glue coating of the backlight module. According to the length of the backlight module frame, the gluing range of the upper end of the gluing tape is adjusted by adjusting the guide structure. The backlight module is lowered onto the gluing table under the action of the adsorption structure, and the glue is transferred to the backlight module frame by the gluing tape.

[0018] Step 3: Display module loading process: the technician places the display module with the glue-coated surface facing upward on the display module positioning platform 1, and uses the electric guide rail 1 and the moving component to transfer the display module to the display module positioning platform 2;

[0019] Step 4: Laminating and assembling. After transferring the glued backlight module to the top of the second display module positioning platform by using the adsorption structure, the backlight module is lowered onto the display module and a moderate laminating pressure is applied. The glued part of the backlight module frame is laminated with the two end walls of the upper end of the display module to complete the assembly and form a module assembly accessory.

[0020] Step 5: Module unloading processing, use the moving component at the second display module positioning platform to push the module assembly parts upward, and then transfer them outward under the action of the second electric guide rail to complete the module fitting assembly.

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] (1) The present scheme is to set up a gluing table with a pair of gluing tanks and to convey a gluing tape immersed in the gluing tanks. Adjustment guide structures for guiding and positioning the upper ends of the gluing tape are installed on the front and rear sides of the upper end of the gluing table. According to the length of the backlight module frame, the spacing between the pair of positioning rollers for guiding and conveying the upper end of the gluing tape can be adjusted by rotating the bidirectional screw on the adjustment guide structure to adjust the length of the gluing tape protruding horizontally upward so that its length matches the length of the backlight module frame to be glued. When working, the backlight module can be lowered onto the gluing table by using the transmission adsorption structure. The two side frames of the backlight module are respectively in contact with the upper ends of the pair of gluing tapes. The glue liquid is evenly transferred to the frame of the backlight module by using the conveying gluing tape. This not only simplifies the gluing adjustment operation, but also adopts a bottom-up transmission friction gluing method to effectively improve the gluing uniformity and is not prone to glue overflow.

[0023] (2) This solution also cooperates with the backlight module positioning table through the conveying table. When positioning the backlight module, the technician places the backlight module on the backlight module positioning table, and then uses the conveying table to convey the backlight module positioning table to the end of the chain conveyor. The adsorption structure is used to adsorb the backlight module and then convey it to the gluing table. After the display module is placed on the display module positioning table 1, the mobile component located at the display module positioning table 1 is used to prop up the display module and then convey it to the display module positioning table 2. The mobile component set at the display module positioning table 2 can be used to convey the entire module after mounting outward, thereby improving the conveying flexibility. Multiple conveying structures are adapted to improve the continuity of the overall assembly process. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following will combine 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 the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0041] Example 1: The present invention discloses a flat display module bonding and assembly device, see Figure 1-Figure 4 , including an assembly table 1, a conveying table 4 and a conveying table 7 are installed at both ends of the assembly table 1, a backlight module positioning table 5 for conveying the backlight module 6 is slidably installed on the conveying table 4, a display module positioning table 1 8 and a display module positioning table 2 9 for positioning the display module 10 are fixedly installed in the front and rear directions of the conveying table 7, and a conveying structure for conveying the display module 10 is also installed on the conveying table 7, the conveying table 4 and the backlight module positioning table 5 cooperate with each other to convey the backlight module 6, and the display module positioning table 1 8, the display module positioning table 2 9 and the conveying structure cooperate with each other to convey the display module 10.

[0042] See also Figure 1 and Figure 5 The rear end of the assembly table 1 is fixedly connected to a chain conveyor 2 located above the conveying table 4 and the conveying table 7. A plurality of adsorption structures 3 for adsorbing and transmitting the backlight module 6 are distributed on the chain conveyor 2. The adsorption structure 3 includes a connecting plate 31 installed on the conveying structure of the chain conveyor 2. A suction cup 33 that can be extended and retracted in the vertical direction is installed on the connecting plate 31 through an electric push rod 32. An adsorption box 34 is installed at the outer end of the connecting plate 31. A micro air pump connected to the suction cup 33 is installed in the adsorption box 34.

[0043] See also Figure 1 and Figure 5 A gluing platform 14 fixed on the assembly platform 1 is provided between the conveying platform 4 and the conveying platform 7. A gluing tank 142 is provided at the upper ends of both the front and rear sides of the gluing platform 14. A gluing belt 16 is installed in the gluing tank 142 through a pair of driving rollers 15 arranged on the left and right. Adjustment guide structures for guiding and positioning both sides of the upper end of the gluing belt 16 are installed at the front and rear sides of the upper end of the gluing platform 14.

[0044] Among them, see Figure 6-Figure 9 The adjustment guide structure includes an operation box 18 fixed on the glue coating table 14, a bidirectional screw 20 is rotatably installed in the operation box 18, a handle or a driving motor is externally connected to the outer end of the bidirectional screw 20, and both ends of the bidirectional screw 20 are threadedly connected with a moving block 19, and the outer end of the moving block 19 is fixedly connected with a positioning roller 17 for guiding and positioning the glue coating tape 16;

[0045] The positioning roller 17 includes a guide rod fixed to the outer end of the moving block 19, and a guide roller for conveying the positioning roller 17 is rotatably sleeved on the guide rod. According to the length of the frame of the backlight module 6, it is only necessary to rotate the bidirectional screw 20 in advance to adjust the distance between the pair of positioning rollers 17. The length of the adhesive tape 16 protruding horizontally upward is adjusted by adjusting the spacing between the pair of positioning rollers 17, so that the length of the adhesive tape 16 between the pair of positioning rollers 17 is consistent with the length of the frame of the backlight module 6 to be coated with glue. The adhesive tape 16 is provided with a section of elastic band 161, which is used to play a traction compensation role on the adhesive tape 16 when the adhesive application range of the adhesive tape 16 is adjusted by the pair of positioning rollers 17, so that the adhesive tape 16 still maintains a good tensioning effect after adjustment, so that the adhesive liquid can be evenly loaded during the conveyance of the adhesive tape 16 in the adhesive dipping tank 142;

[0046] The glue-coated tape 16 can be circulated and transmitted inside the glue dipping tank 142 under the rotation drive of the driving roller 15, so that the glue-coated tape 16 is not immersed in glue. When the backlight module 6 is pushed onto the supporting plate 141 under the action of the adsorption structure 3, the glue-coated parts of the frames on both sides of the backlight module 6 are just in contact with the upper end surfaces of a pair of glue-coated tapes 16, and the glue-coated tape 16 that is not immersed in glue transfers the glue to the frame of the backlight module 6. In this process, the driving roller 15 can be used to drive the glue-coated tape 16 to transmit for a certain distance, which makes it easier for the glue to be evenly coated on the frame of the backlight module 6 under the action of friction, thereby effectively achieving uniform distribution of the glue.

[0047] See also Figure 10-Figure 14 During operation, the technician places the backlight module 6 with the glue-coated surface facing downward on the backlight module positioning platform 5, and uses the conveying platform 4 to convey the backlight module positioning platform 5 to the end of the chain conveyor 2, and then uses the adsorption structure 3 on the chain conveyor 2 to adsorb and clamp the backlight module 6, and after conveying the positioned backlight module 6 to the top of the glue coating platform 14, the backlight module 6 is lowered by the electric push rod 132 until its frame contacts the upper end surfaces of a pair of glue coating belts 16, and the glue in the glue dipping tank 142 is transferred to the frame of the backlight module 6 by the transmission glue coating belt 16;

[0048] During the gluing process of the backlight module 6, the technician places the display module 10 with the glued surface facing up on the display module positioning platform 1 8, and uses the conveying structure to convey the display module 10 to the display module positioning platform 2 9. The mobile component 13 retreats, and after the display module 10 is positioned on the display module positioning platform 2 9, the adsorption structure 3 is used to convey the glued backlight module 6 to the top of the display module positioning platform 2 9, and the backlight module 6 is lowered onto the display module 10 and given appropriate fitting pressure. The glued part of the frame of the backlight module 6 is fitted with the two end walls of the upper end of the display module 10 to complete the assembly, and finally the assembled module is conveyed out by the conveying structure.

[0049] Embodiment 2: Based on Embodiment 1, this embodiment optimizes the backlight module positioning platform 5, the display module positioning platform 1 8, the display module positioning platform 2 9 and the transmission structure, as follows:

[0050] See also Figure 1-Figure 3 The backlight module positioning platform 5 is a rectangular frame structure with an empty slot at the upper end. A positioning slot 501 adapted to the backlight module 6 and connected to the empty slot is provided at the upper end of the backlight module positioning platform 5. When positioning the backlight module 6, the technician places the backlight module 6 on the backlight module positioning platform 5. The left and right end walls of the backlight module 6 fit with the positioning slot 501, which is convenient for positioning. The backlight module positioning platform 5 is then transferred to the end of the chain conveyor 2 by the transfer platform 4. The backlight module 6 is adsorbed by the adsorption structure 3 and then transferred to the gluing platform 14.

[0051] See also Figure 4 The display module positioning platform 1 8 and the display module positioning platform 2 9 are provided with through slots with upper and lower and left and right openings in the middle. The display module positioning platform 1 8 and the display module positioning platform 2 9 are provided with inner card slot 1 801 and inner card slot 2 901 respectively on the left and right sides of the upper ends thereof, which are adapted to the display module 10 and connected to the through slots.

[0052] The conveying structure includes an electric guide rail 11 and an electric guide rail 2 12 installed on both sides of the conveying platform 7. A moving assembly 13 that can move forward and backward in the horizontal direction is installed on the electric guide rail 11 and the electric guide rail 2 12. The moving assembly 13 includes a moving seat 131 that is installed for horizontal sliding. A lifting platform 133 is fixedly installed on the moving seat 131 through a pair of electric push rods 2 132. A display module positioning platform 1 8 and a display module positioning platform 2 9 with the same structure are arranged in front and behind. The position of the display module positioning platform 2 9 corresponds to the position of the gluing platform 14.

[0053] See also Figure 10-Figure 14 When in use, the technician places the display module 10 on the display module positioning platform 18, and uses the inner card slot 1801 on the display module positioning platform 18 to position the display module 10, which is convenient for the technician to place and position the display module 10, and then uses the moving component 13 located at the display module positioning platform 18 to push the display module 10 upward and then transfer it to the display module positioning platform 29. After being transferred to the top of the display module positioning platform 29, the moving component 13 is reset downward until the display module 10 is stuck on the inner card slot 2901 of the display module positioning platform 29, completing the directional loading of the display module 10;

[0054] The mobile component 13 arranged at the display module positioning platform 29 is arranged away from the display module positioning platform 29 under the action of the electric guide rail 21 in the initial state, so as to facilitate the display module 10 on the front mobile component 13 to be transferred to the display module positioning platform 29 through the electric guide rail 11. When fitting and assembling, the electric guide rail 11 will return the mobile component 13 adapted thereto to the display module positioning platform 18, and the electric guide rail 12 will push the mobile component 13 adapted thereto to the bottom of the display module positioning platform 29, so as to support the display module 10 positioned at the display module positioning platform 29 and improve the stability during the fitting and assembling process, and secondly, it can be used to transfer the entire module after mounting outwards and improve the transfer flexibility.

[0055] According to embodiments 1 and 2, the present invention also provides a flat display module bonding and assembly process, see Figure 10-Figure 14 , including the following steps:

[0056] Step 1: The backlight module 6 is loaded. The technician places the backlight module 6 with the glue-coated surface facing downward on the backlight module positioning platform 5. The left and right end walls of the backlight module 6 fit with the positioning groove 501 for easy positioning. The backlight module positioning platform 5 is then transferred to the bottom of the adsorption structure 3 at the end of the chain conveyor 2 by the transfer platform 4. The suction cup 33 is driven downward by the electric push rod 32, and the adsorption structure 3 adsorbs and clamps the backlight module 6.

[0057] Step 2: Glue coating of the backlight module 6. According to the length of the frame of the backlight module 6, the distance between the pair of positioning rollers 17 is adjusted by rotating the bidirectional screw 20, so as to adjust the gluing range of the upper end of the glue coating tape 16 by adjusting the distance between the pair of positioning rollers 17. The backlight module 6 is lowered onto the glue coating table 14 under the action of the adsorption structure 3. The glue coating of the frame on both sides of the backlight module 6 below the backlight module 6 just contacts with the upper end surface of the pair of glue coating tapes 16. The glue coating tapes 16 in the conveying process are used to transfer the glue to the frame of the backlight module 6.

[0058] Step 3: Loading of the display module 10. The technician places the display module 10 with the glue-coated surface facing upward on the display module positioning platform 1 8. The display module 10 is transferred to the display module positioning platform 2 9 by using the electric guide rail 1 1 and the moving component 13. The moving component 13 is reset downward until the display module 10 is stuck in the inner card slot 2 901 of the display module positioning platform 2 9. The directional loading of the display module 10 is completed. The moving component 13 is reset to the display module positioning platform 1 8.

[0059] Step 4: Fitting and assembling processing, the electric guide rail 12 pushes the matching moving component 13 to the bottom of the display module positioning platform 9, the upper end surface of the lifting platform 133 contacts the lower end surface of the display module 10, and the backlight module 6 after being coated with glue is transferred to the top of the display module positioning platform 9 by using the adsorption structure 3, and then the backlight module 6 is lowered onto the display module 10, and a moderate fitting pressure is applied, and the glue coating of the frame of the backlight module 6 is fitted with the two end walls of the upper end of the display module 10 to complete the assembly and form a mold assembly accessory;

[0060] Step 5: Module blanking processing, using the moving component 13 at the display module positioning platform 2 9 to push the module assembly parts upward and then transfer them outward under the action of the electric guide rail 2 12 to complete the module fitting assembly.

[0061] In summary, a glue coating platform 14 with a pair of glue dipping tanks 142 is provided, and a glue coating belt 16 that can be conveyed by a pair of driving rollers 15 is provided in the glue dipping tank 142. The glue coating belt 16 is immersed in the glue solution in the glue dipping tank 142. Adjustable guide structures for guiding and positioning the upper ends of the glue coating belt 16 are installed on the front and rear sides of the upper end of the glue coating platform 14. According to the length of the frame of the backlight module 6, the distance between the pair of positioning rollers 17 for guiding and conveying the upper end of the glue coating belt 16 can be adjusted by rotating the bidirectional screw 20 on the adjusting guide structure, so as to adjust the length of the glue coating belt 16 protruding horizontally upward, so that its length is adapted to the length of the frame of the backlight module 6 to be glued.

[0062] During operation, it is only necessary to use the transmission adsorption structure 3 to lower the backlight module 6 onto the glue coating table 14, and the two side frames of the backlight module 6 are respectively in contact with the upper ends of a pair of glue coating tapes 16, and the glue liquid is evenly transferred to the frames of the backlight module 6 using the transmission glue coating tapes 16. This not only simplifies the gluing adjustment operation, but also adopts a bottom-up transmission friction gluing method, which effectively improves the gluing uniformity and is not prone to glue overflow problems.
