[0026] In order to realize the automatic unloading of the rolled film 2, a unloading mechanism 4 is set, which includes a base 41. The top center of the base 41 is rotatably connected to a unloading shaft 42 through a bearing. A unloading roller 43 is clamped on the top of the unloading shaft 42. The rolled film 2 is wrapped around the surface of the unloading roller 43. A torsion spring 44 is also movably sleeved on the arc surface of the unloading shaft 42. The top of the torsion spring 44 is fixedly installed on the bottom of the unloading roller 43, and the bottom end of the torsion spring 44 is fixedly installed on the top of the base 41.

[0027] Specifically, a torsion spring 44 is movably sleeved on the arc surface of the discharge shaft 42, and the tension of the discharge roller 43 can be adjusted through the elastic action of the torsion spring 44 to ensure that the tension of the roll film 2 is moderate during the discharge process, thereby avoiding damage to the film material or uneven discharge caused by excessive tension. Through the design of the discharge mechanism 4, the automatic discharge action of the roll film 2 can be realized without manual intervention, thereby improving production efficiency and automation level.

[0028] In order to realize the automatic rotation action of the backlight film during the edge bonding, an edge bonding rotation mechanism 5 is set, including a rotating shaft 51, the bottom end of the rotating shaft 51 passes through and extends to the bottom of the operating top plate 3, and a rotating motor 52 is fixedly installed on the bottom of the operating top plate 3, and the output shaft of the rotating motor 52 is fixedly installed on the bottom end of the rotating shaft 51 through a coupling, and a clamping plate 53 is fixedly installed on the top of the rotating shaft 51, and a first suction cup 54 is installed in an array on the surface of the clamping plate 53, and the suction ends of multiple first suction cups 54 are in contact with the bottom of the backlight module.

[0029] Specifically, through the design of the rotating motor 52 and the rotating shaft 51, the automatic rotation of the backlight film during the pasting process is realized, without manual intervention, thereby improving the degree of automation and efficiency of the operation; a first suction cup 54 is installed on the surface of the clamping plate 53, which can ensure that the backlight module is firmly fixed on the clamping plate 53, and the design of multiple suction cups enables the backlight module to maintain a stable position and angle during the pasting process, thereby achieving precise pasting operation; the design of the automatic rotating mechanism makes the pasting process faster and more efficient, reduces the operator's manual operation time, and improves production efficiency.

[0030] In order to realize the movement and adjustment of the roll film 2 during unwinding; a film pulling adjustment mechanism 6 is set up, including a column 61, and the two columns 61 are distributed on both sides of the top of the rear section of the operating top plate 3, and are fixedly installed on the top of the operating top plate 3, and a transverse slide rail 62 is fixedly installed on the top of the two columns 61, and a slider 63 is slidably inserted on the surface of the transverse slide rail 62, and a transverse cylinder 64 is also fixedly installed on one end of the top of the transverse slide rail 62, and the telescopic end of the transverse cylinder 64 is fixedly installed on the surface of the slider 63.

[0031] Specifically, through the combined design of the vertical column 61, the horizontal slide rail 62, the slider 63 and the horizontal cylinder 64, the movement and adjustment function of the roll film 2 during the unwinding process is realized, and the position and tension of the roll film 2 can be adjusted as needed, making the operation more flexible and precise; the use of the horizontal cylinder 64 makes it possible to realize automatic operation of the movement and adjustment of the roll film 2 during the unwinding process, reducing the need for manual intervention and improving work efficiency and consistency;.

[0032] A movable electric telescopic rod 65 is fixedly installed on the top of the slider 63, and a U-shaped plate 66 is fixedly installed on the telescopic end of the movable electric telescopic rod 65. A driving plate 67 is fixedly installed on both ends of the U-shape of the U-shaped plate 66, and a second suction cup 68 is fixedly installed on one end of the driving plate 67.

[0033] Specifically, a driving plate 67 is fixedly installed at both ends of the U-shaped plate 66, and a second suction cup 68 is fixedly installed at one end of the driving plate 67. Through the contact between the two second suction cups 68 and the roll film 2, the position of the roll film 2 can be better fixed and controlled, avoiding displacement or loosening during operation; through the contact between the second suction cup 68 and the roll film 2, the force on the roll film 2 can be made more uniform, reducing the risk of deformation or damage of the roll film 2 due to single-point force; the telescopic end of the mobile electric telescopic rod 65 is fixedly installed with a U-shaped plate 66, and the telescopic adjustment of the U-shaped plate 66 can be achieved by controlling the telescopic action of the electric telescopic rod, thereby adjusting the extrusion force of the roll film 2 in contact with the backlight source module, thereby enhancing adhesion.

[0034] In order to achieve the action of uniform adhesion of the rolled film 2 after being attached; a coating mechanism 7 is set up, including a coating wheel 71, a slide groove 72 is opened on the surface of the driving plate 67, a slide seat 73 is slidably inserted into the inner wall of the slide groove 72, a U-shaped seat 74 is fixedly installed on one end of the slide seat 73, and the two end surfaces of the U-shaped seat 74 are rotatably connected to a coating shaft 75 through a bearing, the arc surface of the coating shaft 75 is fixedly installed on the surface of the coating wheel 71, and the surface of the coating wheel 71 is in contact with the surface of the rolled film 2, and bearing seats 76 are fixedly installed on the two end surfaces of one side of the driving plate 67, and the relative surfaces of the two bearing seats 76 are rotatably connected with screws 77 through bearings, and a driving motor 78 is also fixedly installed on the surface of one of the bearing seats 76, and the output end of the driving motor 78 is fixedly installed on the relative surface of the screw 77 through a coupling, and the threaded surface of the screw 77 is threadedly connected to the surface of the sliding seat 73.

[0035] Specifically implemented in this way, the smear wheel 71 contacts the surface of the roll film 2, and through the precise control of the screw 77, the smear wheel 71 can move evenly on the surface of the roll film 2. This helps to ensure the uniform bonding effect of the roll film 2 after attachment, avoiding problems such as uneven local bonding or wrinkling; the drive motor 78 drives the screw 77 to rotate through the coupling, and the rotation of the screw 77 will drive the slide 73 to move along the slide groove 72. This precise positioning and movement function allows the smear wheel 71 to move evenly along the predetermined trajectory on the surface of the roll film 2; the smear wheel 71 contacts the surface of the roll film 2, and by evenly distributing pressure on the roll film 2, it ensures uniform bonding of the roll film 2, avoiding problems such as poor bonding or wrinkling in local areas.

[0036] In order to realize the automatic shearing action after the roll film 2 is pasted; a shearing mechanism 8 is set, including an L connecting plate 81, the bottom end of the L connecting plate 81 is fixedly installed on the top of the driving plate 67, and the other end bottom of the L connecting plate 81 is fixedly installed with a shearing electric telescopic rod 82, and the telescopic bottom end of the shearing electric telescopic rod 82 is fixedly installed with a cutting blade 83.

[0037] Specifically, through the shearing electric telescopic rod 82, the mechanism can realize the automatic shearing action after the roll film 2 is attached, thereby improving production efficiency and reducing the need for manual intervention; the cutting blade 83 is fixedly installed at the bottom end of the shearing electric telescopic rod 82, and through precise control, precise cutting of the roll film 2 can be achieved, ensuring the accuracy and consistency of the cutting.

[0038] By setting up a feeding mechanism 4, an edge-fitting rotating mechanism 5, a film-pulling adjusting mechanism 6, a coating mechanism 7 and a shearing mechanism 8, multiple functional modules such as feeding, edge-fitting, film-pulling, coating and shearing are integrated to realize the automated production of the edge-wrapping film of the backlight module, thereby improving the production efficiency and quality stability; the edge-fitting rotating mechanism 5 can accurately position and rotate the backlight module to ensure the accurate position during the film-fitting process and avoid deviation or misalignment; the film-pulling adjusting mechanism 6 can adjust the pulling force and tension during the film-fitting process to make the film-fitting process smoother and avoid unsatisfactory film-fitting effect caused by uneven pulling force; the coating mechanism 7 can make the backlight module and the film evenly bonded, thereby improving the adhesion and firmness of the film; automated production is realized, the production efficiency and film-fitting quality are improved, and at the same time the labor cost and operation complexity are reduced.

[0039] Working principle: During operation, the backlight source module is placed on top of the plurality of first suction cups 54, and the suction cups are used for suction and clamping. The rotating motor 52 at the bottom controls one side surface of the backlight source module to be arranged parallel to the driving plate 67, and controls the moving electric telescopic rod 65 to extend and drive the U-shaped plate 66 to move forward, thereby controlling the second suction cup 68 on the surface of the driving plate 67 to contact with the roll film 2 on the surface of the unwinding roller 43 for suction;

[0040] The horizontal cylinder 64 is extended to drive the slider 63 to slide on the surface of the horizontal slide rail 62, so that the roll film 2 sucked by the suction cup is stretched and unfolded to be placed parallel to the surface of the backlight module, and the moving electric telescopic rod 65 is continued to be controlled to extend and drive the roll film 2 to contact and bond with the surface of the backlight module, and at the same time, the drive motor 78 works forward and reversely, driving the screw 77 to rotate forward and reversely, thereby controlling the slide 73 to reciprocate, thereby driving the coating wheel 71 at one end to roll, driving the surface of the roll film 2 to squeeze and contact with the surface of the backlight module, so that it is evenly bonded, and after the bonding is completed, the second suction cup 68 is controlled to release the suction state and move away from the surface of the backlight module, and the backlight module is driven to rotate 90 degrees by the rotation motor 52, and while rotating, the roll film 2 after the surface bonding is synchronously stretched and unfolded to contact with the other side surface of the backlight module, and then the driving plate 67 is controlled to move forward again, and the surface of the coating wheel 71 is controlled to contact with the surface of the roll film 2 to squeeze the backlight module, and reciprocate again;

[0041] When the four sides of the backlight module have been pasted, the electric telescopic rod 82 at the top is started to drive the cutting blade 83 at the bottom to move downward to cut the roll film 2.

[0042] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
