[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 10 The present invention provides a technical solution: an automatic assembly machine for a backlight module and a glass module, comprising a backlight feeding section, a glass feeding section, an adhesive application section, and a gripping and bonding section, and further comprising:

[0038] The bubble removal unit includes a connecting seat 1 installed at the end of the robotic arm, and the connecting seat 1 can be adjusted with the position of the robotic arm in space.

[0039] Two extrusion parts are installed on the two longitudinal sides of the connecting seat 1, and the two extrusion parts can apply pressure to the glass at the positions of the two longitudinal sides of the bubble;

[0040] A rolling part is installed on the lateral side of the connecting seat 1, and the rolling part and the two extrusion parts form an extrusion area with only one side open, and the rolling part can move the glass along the longitudinal direction and roll;

[0041] A temperature control part is installed on the other lateral side of the connecting seat 1, and the temperature control part can switch the bubble area between heating and cooling states to make the bubble expand or shrink along the longitudinal opening direction.

[0042] When the backlight module and the glass module automatic assembly machine are assembled, the specific assembly process is automatically fed through the backlight feeding part and the glass feeding part. Then, the glue coating part coats the surface of the backlight module, the grabbing and bonding part grabs the liquid crystal glass and bonds it, so as to achieve the purpose of full bonding assembly. This process can be realized by existing mechanical arm or conveying belt, and the existing technology can easily realize it, such as the mode described in the patent publication No. CN113311603A. Therefore, the process will not be described in detail.

[0043] However, in the actual bonding process, although the liquid crystal glass can be bonded in an inclined manner, there are still bubbles between the liquid crystal glass and the backlight module. Although the assembly workshop is a dust-free environment, the dirt carried by the liquid crystal glass or the backlight module may also be caused by human factors. Therefore, there may be nucleated bubbles in the bubbles during the bonding of the liquid crystal glass. Compared with pure bubbles, nucleated bubbles cannot be directly extruded out of the edge, which may cause damage to the liquid crystal glass or the backlight module. If rework is performed, not only the process is more complex, but also the investment cost and time are longer. Therefore, the nucleated bubbles are mainly treated in the present application, and the specific implementation manner is as follows:

[0044] After the liquid crystal glass is bonded, the bubble removing part moves to the position directly above the bubble by the mechanical arm or the three-dimensional moving platform, and then stops. The extrusion parts installed on the two sides of the connecting seat 1 apply pressure to the two sides of the bubble position. At the same time, the rolling part cooperates with the two extrusion parts to form an extrusion area with only one side outlet, so as to limit the flow and expansion direction of the bubble, as shown in Figure 9 The bubble flow and expansion direction is directed to the position closest to the edge. After the area is limited, the temperature control part heats the bubble area to make the bubble expand, and due to the cooperation of the rolling part and the extrusion part, the bubble can only expand and extend in one direction. The expansion and extension of the bubble can provide direction and space for the movement of the nucleated material in the bubble.

[0045] After the expansion is completed, the glass is moved and rolled in the longitudinal direction (i.e. the opening on one side is reversed) by the rolling part, the nucleation material is moved to the edge by the optical glue, and in the process of rolling, the temperature control part cools the bubble area to reduce the bubble, so that the bubble and the nucleation material inside it can be moved by the rolling part to push the optical glue to flow.

[0046] Then the connecting seat 1 adjusts the position through the mechanical arm or three-dimensional moving platform, and then repeats the above process to move the nucleation material through the optical glue pupa, and the process is repeated until the nucleation material and the bubble are excluded from the edge. Such discharge method can not only avoid direct pushing of the nucleation material to cause damage to the liquid crystal glass or backlight module, but also can make the bubble space increase when the air is heated and expanded, thereby reducing the contact force between the nucleation material and the bubble, which is more conducive to the movement of the nucleation material.

[0047] Moreover, it is worth noting that the heating of the bubble area can improve the flowability of the optical glue in this local position, and in the process of cooling, the bubble is reduced and the rolling part is pushed, which can make the bubble shrink on the side behind the expansion extension direction. This can also help the flow of the nucleation material to minimize the impact of the nucleation material moving under the surface.

[0048] After the bubble is removed, the optical glue can be cured by irradiation of the ultraviolet lamp to complete the bonding process. It is worth mentioning that this bubble removal method is suitable for UV optical glue bonding process, so that the heating and cooling of the temperature will not cause the UV glue to be cured in advance and affect the defoaming effect.

[0049] In one of the more preferred embodiments, an embodiment of the temperature control part is provided.

[0050] The temperature control part comprises two fixed seats 14 fixed at the bottom of the connecting seat 1, and a fixed shaft 16 fixed between the two fixed seats 14. The outer wall of the fixed shaft 16 is provided with a sleeve 7 which can rotate and adjust reciprocally. The inner wall of the sleeve 7 is provided with a piston rod 8 which is slidably installed by a piston. The bottom end of the piston rod 8 penetrates out of the bottom of the sleeve 7 and is fixed with a mounting shell 9. The mounting shell 9 is installed with a thermoelectric module 10, and the thermoelectric module 10 is electrically connected with an external power supply assembly. A cavity is provided between the sleeve 7 and the fixed shaft 16, and the outer wall of the fixed shaft 16 in the cavity is fixed with a winding wheel 17. The outer wall of the winding wheel 17 is fixed and wound with a pull rope 18, and one end of the pull rope 18 penetrates into the cavity of the sleeve 7 and is fixedly connected with the piston. The inner top of the sleeve 7 is connected with the piston through a spring 19.

[0051] The temperature control part further comprises a trigger switch 26 installed on the inner wall of the sleeve 7, and the trigger switch 26 is electrically connected with the thermoelectric module 10.

[0052] For details, please refer toFigure 4 and Figure 7 In the initial state, the sleeve 7 is in a vertical state and is located above the bubble area. At this time, the piston and the trigger switch 26 are in contact. Then the trigger switch 26 will control the downward side of the thermoelectric module 10 to heat up, thereby heating the local area in the bubble area and achieving the purpose of heating the bubble.

[0053] After heating is complete, the sleeve 7 is driven to swing by an external structure, causing it to move towards... Figure 4 The piston rod oscillates counterclockwise (in the direction of bubble expansion and extension), and while the sleeve 7 rotates, the winding wheel 17 and the fixed shaft 16 remain stationary. Therefore, the rotation of the sleeve 7 is equivalent to unwinding the rope 18. As a result, the piston rod 8 extends outward under the elastic force of the spring 19. This allows the mounting shell 9 below the piston rod 8 and the thermoelectric module 10 to maintain a small distance from the glass surface. Simultaneously, as the piston and piston rod 8 extend, the piston disengages from the trigger switch 26. The trigger switch 26 then controls the downward-facing side of the thermoelectric module 10 to cool down, thereby cooling and shrinking the bubble area during its oscillation. During this process, the rolling part causes the bubble to move together. Therefore, as the piston rod 8 rotates, the bubble area moves together and is located below it, thus achieving the purpose of temperature control of the bubble area.

[0054] After one extrusion is completed, when the position of the connecting seat 1 is adjusted by the robotic arm or three-dimensional moving platform, the sleeve 7 will rotate in the opposite direction under the drive of the external structure, completing the reset of the piston rod 8 and the piston. At the same time, the piston re-contacts the trigger switch 26, and then the next extrusion can be performed.

[0055] It is worth mentioning that the trigger switch 26 controls the current of the thermoelectric module 10 to reverse, thereby achieving the effect of heating or cooling. Furthermore, by controlling the magnitude of the current, the heat or cold generated by the thermoelectric module 10 can also be controlled, thereby achieving precise temperature control.

[0056] In one preferred embodiment, a method is provided to further enhance the heating or cooling effect;

[0057] The piston divides the sleeve 7 into upper and lower spaces, and both spaces are connected to a gas supply pipe 12 that can discharge gas in one direction. The end of the gas supply pipe 12 is connected to the inner wall of the mounting shell 9, and the gas outlet of the inner wall of the mounting shell 9 is located below the thermoelectric module 10. Both the upper and lower spaces of the sleeve 7 are provided with a gas inlet that can be introduced in one direction.

[0058] For details, please refer to [link / reference]. Figure 4 and Figure 7Because of the gap between the thermoelectric module 10 and the glass surface and the mounting shell 9, and the sleeve 7 and the piston rod 8 in the process of swinging, the space above and below the piston will blow into the mounting shell 9 through the gas pipe 12, so in the process of heating or swing cooling, the gas pipe 12 can blow into the mounting shell 9 without interruption, so as to transport the heat and cold generated by the thermoelectric module 10 downward, thereby improving the heating or cooling effect.

[0059] In one of the more preferred embodiments, an embodiment of the rolling part is provided;

[0060] The rolling part includes a horizontal groove respectively formed in the side wall of the two fixed seats 14, and a movable adjusting sliding block 25 is installed in the horizontal groove, and a reciprocating rotating adjusting elastic expansion rod 5 is jointly installed between the two adjusting sliding blocks 25, and a squeezing roller 6 is rotatably installed at the bottom of the expansion end of the elastic expansion rod 5.

[0061] Specifically, refer to Figure 4 , the elastic expansion rod 5 is driven to reciprocate by the external structure, and the squeezing roller 6 at the expansion end of the elastic expansion rod 5 is driven to squeeze the glass surface, so as to achieve the purpose of moving the bubbles;

[0062] Moreover, it is worth noting that when the sleeve 7 is in a vertical state, the elastic expansion rod 5 is in an inclined state, and when they rotate, they rotate in the same direction and synchronously, so that when the sleeve 7 rotates and switches to cooling, the elastic expansion rod 5 can squeeze the glass surface with the squeezing roller 6, so as to move the bubbles, and because the sleeve 7 rotates, the optical glue under the glass surface will gradually reduce the flowability after the thermoelectric module 10 under the sleeve 7 switches to the cooling state, and at the same time, the elastic expansion of the elastic expansion rod 5 will gradually increase the squeezing degree of the squeezing roller 6 to the glass surface, and the mutual offset can ensure that the squeezing roller 6 can effectively push the optical glue and the bubbles to move together.

[0063] It is worth mentioning that the distance between the adjusting sliding block 25 and the sleeve 7 can also be controlled, so that the position of the squeezing roller 6 can be adjusted according to the size of the bubbles, so as to adapt to bubbles of different sizes.

[0064] In one of the more preferred embodiments, an embodiment of the rolling part is provided;

[0065] The bottom of the connecting seat 1 is equipped with a sliding plate 13 that can be slidably adjusted. The bottom of the sliding plate 13 has an installation cavity, and a slot frame 20 is vertically slidably installed in the installation cavity. The slot frame 20 is connected to the inner wall of the installation cavity with an adjusting airbag 22. The adjusting airbag 22 is connected to an external inflation and deflation mechanism. A rack 21 is provided on the inner wall of the slot at the bottom of the slot frame 20. Transmission gears 15 are provided at the rotation points of the elastic telescopic rod 5 and the sleeve 7, and both transmission gears 15 mesh with the rack 21.

[0066] For details, please refer to [link / reference]. Figure 4 and Figure 8 The sliding plate 13 is adjusted laterally by electric control so that it can drive the slot frame 20 to move back and forth. During the reciprocating movement, the meshing between the rack 21 and the transmission gear 15 can drive the sleeve 7 and the elastic telescopic rod 5 to swing back and forth synchronously, thereby achieving the purpose of pushing the bubble to move.

[0067] When it is necessary to adjust the distance between the sleeve 7 and the elastic telescopic rod 5, the adjusting airbag 22 can be inflated by the external inflation / deflation mechanism, thereby increasing its volume and causing the slot frame 20 to move downward, so that the rack 21 on its inner wall disengages from the transmission gear 15. Then, the position of the elastic telescopic rod 5 can be adjusted by adjusting the slider 25. After the adjustment is completed, the external inflation / deflation mechanism sucks air into the adjusting airbag 22, thereby reducing its volume and causing the slot frame 20 to move upward, so that the rack 21 re-engages with the transmission gear 15.

[0068] In one preferred embodiment, an implementation of the extrusion section is provided;

[0069] The extrusion section includes an insert shaft 2 that is rotatably installed inside the connecting seat 1. The ends of the insert shaft 2 that protrude from both sides of the connecting seat 1 are fixed with side brackets 3. Both side brackets 3 can elastically extend and retract, and the ends of the two side brackets 3 are rotatably installed with side rollers 4. The surface of the side rollers 4 is made of rubber.

[0070] The connecting seat 1 has an internal cavity, and a worm gear 23 is rotatably installed in the cavity. The worm gear 23 is driven by an external servo motor. The outer walls of the two through shafts 2 located in the cavity are fixed with worm wheels 24, and the two worm wheels 24 mesh with the worm gear 23.

[0071] For details, please refer to [link / reference]. Figures 1-3 and Figure 6The worm 23 is driven to rotate by an external servo motor, which drives the worm wheel 24 to rotate, and further drives the penetrating shaft 2, the side bracket 3 and the side roller 4 to swing to the middle, so as to move the side roller 4 to the middle and apply pressure to the glass surface. Since the side roller 4 rotates from outside to inside, it can also have a centralizing tendency on the surrounding optical glue, which can be more conducive to controlling the extension direction of the bubble expansion.

[0072] In one of the more preferred embodiments, the bottom end of the elastic telescopic rod 5 is connected with the extrusion roller 6 in a sleeved and rotating manner, and the outer wall of the extrusion roller 6 is provided with an arc groove for limiting the sliding of the elastic telescopic rod 5.

[0073] Referring to Figure 3 and 4 By the sleeved and rotating connection between the extrusion roller 6 and the elastic telescopic rod 5, when the elastic telescopic rod 5 is initially swung, the extrusion roller 6 rolls on the glass surface until it is about to contact the bubble. At this time, the extrusion roller 6 cannot continue to rotate due to the action of the arc groove, so when the elastic telescopic rod 5 drives the extrusion roller 6 to move, the extrusion roller 6 will change to sliding friction with the glass surface. This not only reduces the influence on the optical glue far from the bubble, but also provides sufficient extrusion to the optical glue under the glass surface during sliding friction, thereby reducing the influence on the optical glue in other positions while ensuring the bubble pushing.

[0074] In one of the more preferred embodiments, the lower portion of the mounting shell 9 is provided with an image collector 11, and when the sleeve 7 is in a vertical state, the image collector 11 is provided with an air gap between the glass surface.

[0075] In one of the more preferred embodiments, a visual detection system is further included, which can collect and detect images of the glass after bonding, identify the bubble position, and identify pure bubbles or nucleated bubbles, and control the moving position of the bubble removing part through the detection result by using an electrical signal.

[0076] If it is a pure bubble, it can be directly extruded by the extrusion roller 6 without the need for the above heating or cooling method, but the above method can also be used.

[0077] The standard parts used in this embodiment can be directly purchased from the market, and the non-standard structural parts according to the description and drawings can also be directly processed according to the existing technical knowledge without any doubt. The connection method of each part uses the mature conventional means in the existing technology, and the machinery, parts and equipment use the conventional models in the existing technology, so specific descriptions are not made here.

[0078] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described. It is intended, therefore, to cover all modifications and adaptions that fall within the scope of the claims and their equivalents.
