Description

Technical Field

[0001] The invention relates to the technical field of display screen product assembly, and in particular to display screen assembly equipment. Background Art

[0002] Display screens can be divided into many types according to their working principles. The most common ones are CRT displays and LCD displays. However, they are more common in large-scale displays and specific applications, such as LED displays. LED displays are widely used in various fields due to their high brightness, high contrast, high clarity, energy saving and environmental protection.

[0003] The existing patent announcement number CN118492895A shows a fully automatic assembly device for an LED display screen. The document shows that "the present invention discloses a fully automatic assembly device for an LED display screen, which relates to the technical field of display screen processing. The present invention includes a processing table, the top of which is provided with an upper bracket, the top of which is fixed with a hydraulic cylinder, the bottom of the telescopic end of the hydraulic cylinder is fixed with a pressing plate, the top front side of the processing table is fixed with a linear motor 2, the top of the moving end of the linear motor 2 is fixed with a loading box, the top rear side of the processing table is fixed with a linear motor 1, the moving end of the linear motor 1 is fixed with a loading box, the top rear side of the processing table is fixed with a linear motor 1, and the moving end of the linear motor 1 is fixed with a loading box. A U-shaped through-hole frame is fixed on the top of the moving end. The present invention drives the U-shaped through-hole frame to align with the loading box in the upper and lower positions through the cooperation of linear motor 1, U-shaped through-hole frame, processing table, linear motor 2, loading box and lifting plate. The assembly device uses the U-shaped through-hole frame and loading box to drive the rear shell and outer frame of the display screen to align and install in the upper and lower directions, thereby avoiding the problem of gaps or uneven appearance during the assembly of the display screen. It can solve the problem of gaps during assembly and ensure the qualified rate of the product. However, it will be found in the actual use process that it has more steps and can only assemble two single parts, which greatly affects the work efficiency.

[0004] The existing display screen assembly process can be roughly divided into several key parts from the core structure, such as the display screen body, control components, outer frame and back cover. These parts work together to assemble into a complete display screen. In terms of assembly methods, it has both the efficient operation of the automated production line and the delicate operation of manual assembly.

[0005] However, during manual assembly, workers need to distribute multiple precision parts to different positions for assembly. Since each part must be installed seamlessly, this places extremely high technical requirements on the assembly workers. Workers need to align the parts accurately to prevent any possible gaps and ensure assembly quality. However, the current assembly method greatly tests the workers' professional skills and affects the overall assembly efficiency to a certain extent. For this reason, we propose a display assembly device. Summary of the invention

The two sliding rods 610 are provided on the sides corresponding to the shrapnel 69, and the inclined surfaces of the inclined rods 67 are movably provided on the top of the placement frame 2. The inclined rods 67 can contact the top of the placement frame 2, drive the sliding rods 610 to move in the straight grooves 68, thereby driving the shrapnel 69 to deform, so that the rear shell can be accurately installed on the back of the display screen.

[0056] Springs three 10 are provided on both sides of the interior of the placement frame 2, and W-shaped plates 9 are provided on the adjacent end faces of the two springs three 10. The outer surfaces of the two W-shaped plates 9 are movably arranged inside the placement frame 2, and the two W-shaped plates 9 clamp the display column inside the placement frame 2 through the corresponding W-shaped plates 9. The display screen can be placed in the middle part of the W-shaped plate 9, and the spring three 10 will drive the W-shaped plate 9 to squeeze the display screen so that it can be installed in the center.

[0057] When using the device, firstly, the outer frame and the back cover of the display screen need to be placed into the flip plate 71 and the flip frame 65 in turn by the mechanical arm. At this time, the main body of the display screen will be placed into the placement frame 2, which will squeeze the W-shaped plate 9 to drive the spring three 10 to deform. At this time, when the display screen completely enters the two W-shaped plates 9, it will be squeezed to the center area by the spring three 10. At this time, the pull rod one 3 can be pulled to drive the spline sleeve 53 set on the end face to rotate. At the same time, the pull rod one 3 will move inside the U-shaped groove 51, and the spline sleeve 53 will drive the spline shaft one 54 to rotate. At the same time, the spline shaft one 54 will drive the ball 516 in the end face to move from the adjacent groove 513 to another groove 513. At this time, the spline shaft 54 will drive the connecting tube 52 to rotate, and because the linkage rod 517 is limited by the cross rod 82, when the connecting tube 52 and the annular bevel groove 59 are rotated, the inclined column 510 in the annular bevel groove 59 will be driven to move, thereby driving the arc plate 518 to slide in the arc groove 519, so that the linkage rod 517 pushes the cross rod 82 to move, so that the cross rod 82 pushes the piston disk 89 to squeeze the gas in the gas cylinder 81, and the squeezed gas is pushed into the pneumatic telescopic rod 85 through the hose 84, which will drive the rack 86 set at the output end of the pneumatic telescopic rod 85 to move, so that the rack 86 drives the gear 87 to rotate, thereby driving the fixed block 88 and the placement frame 2 to rotate, and then the electronic components can be installed.

[0058] When the outer frame needs to be installed, it is necessary to pull the pull rod 3 to move in the U-shaped groove 51, so that the spline sleeve 53 enters the spline shaft 2 55. When the spline shaft 2 55 is driven to rotate, the worm 58 will be driven to rotate, so that the worm 58 drives the worm wheel 57 to rotate, thereby driving the shaft 56 in the worm wheel 57 to rotate. When the shaft 56 rotates, it drives the flip plate 71 to flip, and drives the insertion rod 76 to slide on the outer surface of the ring 73. When the insertion rod 76 slides into the limit groove 74, it drives the limit plate 78 to enter the connecting groove 77, so that the outer frame falls accurately onto the display screen.

[0059] When the rear shell needs to be assembled, it is only necessary to rotate the pull rod 24 to drive the connecting ring 63 to rotate, thereby driving the straight rod 62 to rotate, and the straight rod 62 will drive the transmission wheel 61 to rotate, and the transmission wheel 61 will drive the mutually meshing driven wheels 64 to rotate, thereby driving the transmission rod 66 to rotate, and thus driving the flip frame 65 to rotate. When the flip frame 65 drives the inclined rod 67 to contact the placement frame 2, it will drive the inclined rod 67 to slide in the straight groove 68 and drive the slide bar 610 to move. At this time, the slide bar 610 will drive the spring piece 69 to deform, and the precise content of the flip frame 65 will fall to the back of the display screen for assembly.

[0060] Example 2: Please refer to Fig.14 The present invention provides a technical solution: the end surface of the inclined rod 67 away from the flip frame 65 is provided with a round head 11, and the round head 11 is movably arranged on the top of the placement frame 2, and the arranged round head 11 can better fit on the top of the placement frame 2.
