Furthermore, the device is equipped with a vacuum tube and an adsorption seat, which can increase the accuracy of gripping and fixing the backlight modules.

[0004] In actual operation, considering that the vacuum tube does not have a unidirectional structure, the pressure inside the system decreases and external air may flow in the opposite direction, affecting the stability and accuracy of the suction of items. Furthermore, it cannot clean the inside of the tube, and prolonged use may lead to internal particle blockage. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of a unidirectional structure within the vacuum tube and the inability to clean the interior of the tube, by proposing an assembly mold for a backlight module.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a backlight module assembly mold, including a frame, on which a driving component, a mounting plate and a clamping device are provided via a moving platform. The driving component is used to drive the mounting plate to rise and fall. The end face of the mounting plate is provided with a plurality of suction rods, which are used to pick up module components for clamping and fixing by the clamping device.

[0008] The suction rod is connected to an external vacuum device. Inside the suction rod, there is a one-way structure and a cleaning component.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A backlight module assembly mold includes a frame 1. A driving component 3, a mounting plate 4, and a clamping device are provided on the table of the frame 1 via a moving platform 2. The driving component 3 is used to drive the mounting plate 4 to rise and fall. The end face of the mounting plate 4 is provided with a plurality of suction rods 5. The suction rods 5 are used to pick up module components for clamping and fixing by the clamping device.

[0023] The suction rod 5 is connected to an external vacuum device. Inside the suction rod 5, there is a one-way structure 6 and a cleaning component 7. The one-way structure 6 is used to seal the air inlet of the suction rod 5, and the cleaning component 7 is used to connect the air inlet of the suction rod 5 and clean and prevent the air inlet from becoming blocked.

[0024] It should be added that there are openings connecting to the interior on both sides of the frame 1, and a conveyor is provided at the opening. The mold components are conveyed through the conveyor, and the backlight components and modules are conveyed through the moving platform 2.

[0025] In some embodiments, vacuum adsorption is used to replace manual handling of parts, thereby improving the accuracy of gripping and fixing. The clamping device may be a pair of clamping blocks that are driven to slide by a cylinder.

[0026] Specifically, the driving component is a cylinder, which is used to drive the mounting plate 4 to move.

[0027] Furthermore, the unidirectional structure 6 includes a sealing part 61, and the inner top of the suction rod 5 extends toward the axis to form a stepped part 51. The sealing part 61 is slidably connected to the inner top of the suction rod 5 by a spring 62, and a sealing ring 63 is provided between the other end of the sealing part 61 and the stepped part 51.

[0028] Furthermore, the cleaning component 7 includes a connecting rod 71, which is disposed in the air inlet of the suction rod 5. A rubber component 73 is fixedly connected to the top of the connecting rod 71, and the rubber component 73 slides in contact with the air inlet of the suction rod 5.

[0029] A stop part 72 is fixedly connected to the bottom of the connecting rod 71. The stop part 72 extends to the periphery of the suction rod 5 and abuts against the backlight component.

[0030] It should be added that a suction cup is also fixedly connected to the free end of the suction rod 5. The abutment part 72 is located inside the suction cup. When the suction rod 5 moves down, it drives the suction cup to fit against the surface of the backlight component. During the gradual movement, the backlight component abuts against the abutment part 72, which drives the connecting rod 71 to rise. The connecting rod 71 pushes the sealing part 61, causing the sealing part 61 to disengage from the sealing ring 63, thereby connecting the air inlet of the suction rod 5.

[0031] More specifically, the bottom of the sealing part 61 is provided with a mating part through the recessed groove 611, and the top of the connecting rod 71 is provided with a fixing part 74 through the connecting part 711. A magnetic part 75 is detachably connected inside the fixing part 74. The fixing part 74 engages with the recessed groove 611, and the magnetic part 75 is magnetically attracted to the mating part.

[0032] Specifically, the mating part is a sheet material made of iron, which fixes the connecting rod 71 by attracting the magnetic part 75. Of course, in the prior art, magnetic attraction is often used to connect or fix two objects. When the pulling force of the connecting rod 71 is greater than the attraction force of the magnetic part 75, the connecting rod 71 can be separated.

[0033] In general, the connecting part 711 has a T-shaped cross-section, the fixing part 74 has a concave groove 741 that matches the connecting part 711 inside, the top of the fixing part 74 extends through the bottom along the center line and is arranged in half, and an elastic ring 76 is sleeved on the periphery of the fixing part 74 through an annular groove 742, and the periphery of the elastic ring 76 has a deformation groove 761.

[0034] It is worth mentioning that the elastic ring 76 is made of deformable materials such as rubber and plastic. It deforms by contacting the fixing part 74 through the deformation groove 761, and is fitted around the ring groove 742 to fix the pair of fixing parts 74. The pair of fixing parts 74 close together and are fixed to the connecting part 711 through the concave groove 741.

[0035] Finally, the top edge of the fixing part 74 extends upward to form an extension part 743, the extension part 743 has an L-shaped cross-section, and the magnetic element 75 is provided between the extension parts 743 on both sides.

[0036] Working method: During operation, the mobile platform 2 drives the drive component 3 to move and lift the suction rod 5 to pick up the backlight component, and then clamps the component by moving in conjunction with the clamping device.

[0037] The suction rod 5 moves down to drive the suction cup to fit against the surface of the backlight component. As it moves gradually, the backlight component abuts against the abutment part 72, which drives the connecting rod 71 to rise. The connecting rod 71 pushes the sealing part 61, causing the sealing part 61 to disengage from the sealing ring 63, thus connecting the air inlet of the suction rod 5.

[0038] Then, the connecting rod 71 can be directly separated by pulling it out, and the movable connecting rod 71 cleans the air inlet of the suction rod 5 through the rubber part 73;

[0039] Furthermore, the elastic ring 76 can be disassembled through the deformation groove 761, and the fixing parts 74 on both sides can be unlocked after disengaging from the elastic ring 76, so that the magnetic component 75 can be replaced.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
