[0023] 1. The present invention applies pressure to the bubble area, and utilizes the cooperation of the rolling part and the extrusion part to confine the bubbles in the extrusion area with a single-side opening, and heats the bubbles to expand them. The expansion direction of the heated bubbles is controlled due to the restriction of the rolling part and the extrusion part, which effectively improves the mobility of the nuclei (impurities in the bubbles). Subsequently, the expanded bubbles and their nuclei are pushed to the edge of the glass by the longitudinal rolling of the rolling part, and the bubbles are shrunk by cooling, further pushing them to the edge. The above steps are repeated until the bubbles and their nuclei are completely removed, thereby greatly improving the degassing efficiency.

[0024] Second, the present invention adjusts the heating and cooling of the bubble area to expand and shrink the bubbles, and uses the fluidity of the optical adhesive to push the nuclei to move without direct contact with the nuclei, thereby further reducing the risk of damage to the glass and the module.

DETAILED DESCRIPTION

[0036] The following will be combined with 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 of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also 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 loading part, a glass loading part, a gluing part and a grabbing and laminating part, and also comprising:

[0038] The bubble removal part includes a connection seat 1 installed at the end of the robot arm, and the connection seat 1 can be adjusted in space with the position of the robot arm;

[0039] Two squeezing parts are respectively installed on both sides of the connecting seat 1 along the longitudinal direction, and the two squeezing parts can apply pressure to the glass at both sides of the bubble in the longitudinal direction;

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

[0041] The temperature control part is installed on the other side of the connecting seat 1 in the lateral direction, and the temperature control part can switch the bubble area between the heating and cooling states, so that the bubble can 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 that the backlight loading part and the glass loading part are automatically loaded, and then the gluing part applies glue to the surface of the backlight module, and the grabbing and laminating part grabs the liquid crystal glass and laps it with it to achieve the purpose of full lamination and assembly. This process can be achieved by existing mechanical arms or conveyor belts, etc., and the existing technology can be easily achieved, such as the method described in Patent Publication No. CN113311603A, so the present invention will not repeat the process in detail;

[0043] However, in the actual bonding process, although the liquid crystal glass can be bonded by tilting bonding, bubbles are still inevitably present between the liquid crystal glass and the backlight module. Moreover, although the assembly workshops are dust-free environments, the liquid crystal glass or the backlight module may be dirty, which may also be caused by human factors. Therefore, there may be nucleated bubbles in the bubbles when the liquid crystal glass is bonded. Compared with pure bubbles, nucleated bubbles cannot be directly squeezed out from the edge by extrusion, which may cause damage to the liquid crystal glass or the backlight module. If rework is required, not only the process will be more complicated, but also the investment cost and time will be longer. Therefore, the present invention mainly deals with nucleated bubbles, and the specific implementation method is as follows:

[0044] After the liquid crystal glass is bonded, the bubble removal part will move to the top of the bubble position with the robot arm or the three-dimensional mobile platform and stop, and then the extrusion parts installed on both sides of the connecting seat 1 will apply pressure to both sides of the bubble position. At the same time, the rolling part also cooperates with the two extrusion parts to form an extrusion area with only a single-side outlet to limit the flow and expansion direction of the bubble, such as Fig. 9 As shown, the direction of the bubble flow and expansion is toward the position closest to the edge. After the area is defined, the temperature control part heats the bubble area to expand the bubble due to the heat. 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 nuclei in the bubble.

[0045] After the expansion is completed, the glass is rolled along the longitudinal direction (i.e., in the opposite direction of the opening on one side) by the rolling part, and the nucleated substances are pushed to the edge by the optical adhesive. In the process of rolling, the temperature control part cools down the bubble area to reduce the bubble temperature. In this way, the rolling part pushes the optical adhesive to flow, so that the bubble and the nucleated substances inside it can be moved.

[0046] Then, after the connection seat 1 is adjusted in position by a mechanical arm or a three-dimensional mobile platform, the above process is repeated to drive the nucleation material to move by means of optical colloid pupa. The process is repeated continuously until the nucleation material and the bubbles are removed from the edge. Such a discharge method can not only avoid directly pushing the nucleation material to cause damage to the liquid crystal glass or the backlight module, but also increase the bubble space when the air expands due to heat, thereby reducing the contact force between the nucleation material and the two, which is more conducive to its movement.

[0047] Moreover, it is worth noting that the heating of the bubble area can improve the fluidity of the optical adhesive at this local position, and in the process of cooling, the shrinkage of the bubble and the push of the rolling part will cause the bubble to shrink to the rear side of the expansion extension direction, which can also help the flow of nuclei to minimize the impact of the movement of nuclei under the surface;

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

[0049] In one of the more preferred embodiments, an implementation of a temperature control unit is provided;

[0050] The temperature control part includes two fixed seats 14 fixed at the bottom of the connecting seat 1, and a fixed shaft 16 is fixed between the two fixed seats 14, a sleeve 7 that can be reciprocated and adjusted is installed on the outer wall of the fixed shaft 16, a piston rod 8 is installed on the inner wall of the sleeve 7 through piston sliding, the bottom end of the piston rod 8 passes through the bottom of the sleeve 7 and is fixed with a mounting shell 9, a thermoelectric module 10 is installed in the mounting shell 9, and the thermoelectric module 10 is electrically connected to the external power supply component, a cavity is opened between the sleeve 7 and the fixed shaft 16, and a winding wheel 17 is fixed to the outer wall of the fixed shaft 16 in the cavity, a pull rope 18 is fixed and wound on the outer wall of the winding wheel 17, and one end of the pull rope 18 passes through the cavity of the sleeve 7 and is fixedly connected to the piston, and a spring 19 is connected between the inner top of the sleeve 7 and the piston;

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

[0052] For details, please refer to Figure 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 is in contact with the trigger switch 26, and then the trigger switch 26 controls the downward side of the thermoelectric module 10 to heat up, thereby heating the local position in the bubble area, thereby achieving the purpose of heating the bubble;

[0053] After heating is completed, the sleeve 7 is driven by the external structure to swing to Figure 4 The sleeve 7 is swung counterclockwise (i.e., the direction in which the bubble expands and extends), and while the sleeve 7 rotates, since the winding wheel 17 and the fixed shaft 16 remain stationary, the rotation of the sleeve 7 is equivalent to the unwinding of the pull rope 18, so the piston rod 8 will extend outward under the elastic force of the spring 19, so that the installation shell 9 below the piston rod 8 and the thermoelectric module 10 can be kept as close to the glass surface as possible. At the same time, as the piston and the piston rod 8 extend, the piston will be separated from the trigger switch 26, and then the trigger switch 26 will control the downward side of the thermoelectric module 10 to cool down, and then the bubble area will be cooled and shrunk during its swinging process. In this process, the cooperation of the rolling part will make the bubble move together, so as the piston rod 8 rotates, but the bubble area will move together and be located below it, so as to achieve the purpose of controlling the temperature of the above-mentioned bubble area;

[0054] After one extrusion is completed, when the position of the connecting seat 1 is adjusted by the mechanical arm or the three-dimensional mobile platform, the sleeve 7 will rotate in the opposite direction under the drive of the external structure to complete the reset of the piston rod 8 and the piston, and the piston will re-contact the trigger switch 26, and then the next extrusion can be carried out;

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

[0056] In one of the more preferred embodiments, a method is provided to further improve the heating or cooling effect;

[0057] The piston divides the sleeve 7 into two spaces, upper and lower, and both spaces are connected to a gas pipe 12 that can exhaust air in one direction. The end of the gas 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 an air inlet that can intake air in one direction.

[0058] For details, please refer to Figure 4 and Figure 7Since there is a gap between the thermoelectric module 10 and the mounting shell 9 and the glass surface, and during the swinging of the sleeve 7 and the piston rod 8, air is blown from the space above and below the piston into the mounting shell 9 through the air pipe 12. Therefore, during the heating or swing cooling process, the air pipe 12 can continuously blow air into the mounting shell 9, thereby transporting 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 implementation of a rolling portion is provided;

[0060] The rolling part includes transverse grooves respectively opened on the side walls of the two fixed seats 14, and an adjustable slider 25 that can be moved and adjusted is installed in the transverse groove. An elastic telescopic rod 5 that can be reciprocated and adjusted is installed between the two adjusting sliders 25, and an extrusion roller 6 is rotatably installed at the telescopic end at the bottom of the elastic telescopic rod 5.

[0061] For details, please refer to Figure 4 , the elastic telescopic rod 5 is driven to rotate back and forth by the external structure to drive the squeezing roller 6 at its telescopic end to squeeze the glass surface, so as to achieve the purpose of pushing the bubble to move;

[0062] Moreover, it is worth noting that when the sleeve 7 is in a vertical state, the elastic telescopic rod 5 is in an inclined state, and the two rotate in the same direction and synchronously, so that when the sleeve 7 rotates and switches to cooling, the elastic telescopic rod 5 can squeeze the glass surface with the squeezing roller 6 to promote the movement of the bubbles, and because the sleeve 7 rotates, the thermoelectric module 10 below it switches to the cooling state, and the fluidity of the optical glue under the glass surface will gradually decrease. At the same time, the elastic expansion and contraction of the elastic telescopic rod 5 will gradually increase the squeezing force of the squeezing roller 6 on the glass surface, and the mutual offset of the two 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 slider 25 and the sleeve 7 can also be controlled by adjusting the slider 25, so that the position of the squeezing roller 6 can be adjusted according to the size of the bubble to adapt to bubbles of different sizes.

[0064] In one of the more preferred embodiments, an implementation method is provided that can drive the sleeve 7 and the elastic telescopic rod 5 to swing back and forth synchronously;

[0065] A sliding plate 13 that can be slidably adjusted is installed at the bottom of the connecting seat 1, and an installation cavity is opened at the bottom of the sliding plate 13, and a notch frame 20 is vertically slidably installed in the installation cavity. The notch frame 20 is connected to the inner wall of the installation cavity with an adjustment air bag 22, and the adjustment air bag 22 is connected to the external inflation and deflation mechanism. A rack 21 is opened on the inner wall of the bottom notch of the notch frame 20, and transmission gears 15 are arranged at the rotation points of the elastic telescopic rod 5 and the sleeve 7, and the two transmission gears 15 are meshed with the rack 21.

[0066] For details, please refer to Figure 4 and Figure 8 , the sliding plate 13 is adjusted laterally by electric control so that it can drive the notch frame 20 to move back and forth, and in the process of reciprocating movement, the meshing action 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 and deflation mechanism, thereby increasing its volume and driving the notch frame 20 to move downward, so that the rack 21 on the inner wall is disengaged from the transmission gear 15, and 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 and deflation mechanism sucks air into the adjusting airbag 22, thereby reducing its volume and driving the notch frame 20 to move upward, so that the rack 21 and the transmission gear 15 can be re-engaged.

[0068] In one of the more preferred embodiments, an implementation of an extrusion portion is provided;

[0069] The extrusion part includes an insertion shaft 2 which is rotatably installed inside the connection seat 1. The ends of the insertion shaft 2 which pass through the connection seat 1 on both sides are fixed with side brackets 3. Both side brackets 3 can be elastically retracted, and the ends of the two side brackets 3 are rotatably installed with side rollers 4. The surface of the side rollers 4 is set to be made of rubber material.

[0070] A cavity is provided inside the connecting seat 1 , and a worm 23 is rotatably installed in the cavity. The worm 23 is driven by an external servo motor. Worm wheels 24 are fixed to the outer walls of the two interlaced shafts 2 in the cavity, and the two worm wheels 24 are meshed with the worm 23 .

[0071] For details, please refer to Figure 1-3 and Figure 6The worm 23 is driven to rotate by an external servo motor, which can drive the worm wheel 24 to rotate, and then drive the interlaced shaft 2, the side bracket 3 and the side roller 4 to swing toward the middle, so as to achieve the effect of the side roller 4 moving in the middle and applying pressure to the glass surface. Moreover, since the side roller 4 rotates from the outside to the inside, it can also have a tendency to gather the surrounding optical glue, which can be more conducive to controlling the extension direction of the bubble when it expands.

[0072] In one of the more preferred embodiments, the bottom end of the elastic telescopic rod 5 is arranged to be rotatably connected to the squeezing roller 6, and the outer wall of the squeezing roller 6 is provided with an arc groove for the elastic telescopic rod 5 to pass through and slide to limit.

[0073] See also Figure 3 and 4 By means of the rotating connection between the squeezing roller 6 and the elastic telescopic rod 5, the squeezing roller 6 can roll the glass surface when the elastic telescopic rod 5 is initially swung until it is about to contact the bubble. The squeezing roller 6 cannot continue to rotate under the action of the arc groove. Therefore, when the elastic telescopic rod 5 swings and drives the squeezing roller 6 to move, the squeezing roller 6 and the glass surface will be transformed into sliding friction, which can not only reduce the impact on the optical glue at a position far away from the bubble, but also provide sufficient squeezing effect on the optical glue under the glass surface during sliding friction, thereby reducing the impact on the optical glue at other positions while ensuring the bubble is pushed.

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

[0075] In one of the more preferred embodiments, a visual inspection system is also included, and the visual inspection system can capture and inspect images of the bonded glass, mark the bubble positions, and identify pure bubbles or nucleated bubbles, and use electrical signals to control the moving position of the bubble removal part based on the inspection results.

[0076] If the detection is pure bubbles, it is not necessary to use the above-mentioned heating or cooling method, and can be directly squeezed through the squeezing roller 6, but the above-mentioned method can also be applied.

[0077] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0078] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
