[0002] In the manufacturing process of LCD screens, the precision of the back panel and front panel components is one of the main factors affecting the quality of the finished product.

[0003] In existing technologies, the assembly of the front panel and back panel is typically done manually. During manual operation, the protective film on the adhesive tape on the front panel must first be removed before transferring it to the back panel for assembly. This process is prone to accidental contact with the adhesive strip, causing contamination and affecting adhesion. Furthermore, manual assembly relies on the operator's experience and patience; prolonged work can lead to operator fatigue, resulting in misalignment and product quality issues. Additionally, during assembly, the front and back panels need to be pressed together to ensure a stable connection; inconsistent pressure during manual pressing can easily damage the panel or cause unstable bonding. Moreover, manual labor is labor-intensive and inefficient. Therefore, how to assemble the front and back panels to improve assembly efficiency and stability is a problem that those skilled in the art need to consider. Utility Model Content

[0017] The present invention will be further described in detail below with reference to specific embodiments: like Figures 1-8 As shown, this utility model is applied to the assembly of a back panel and a front panel in the manufacturing process of a liquid crystal display (LCD). The back panel is placed on a second platform, and the front panel is placed on a first platform. A vision device first collects the position information of the back panel. A first transfer component picks up the front panel and adjusts its posture so that the side with the adhesive strip faces the operator. The operator then removes the protective film from the adhesive strip and moves the front panel directly below the vision device to collect its position information. Based on the collected position information of the back panel and the front panel, the first transfer component adjusts the posture of the front panel and drives it downwards to assemble with the back panel. Finally, a pressure plate presses the front panel against the back panel to ensure a tight fit between the front panel and the back panel. Specifically: A backplate assembly device includes a machine base 1, a first carrier 2, a pressing component 3, and a first transfer component 4 disposed on the machine base 1.

[0018] The first platform 2 includes a first carrier plate 21, with multiple parallel support rods 22 symmetrically arranged on both sides of the first carrier plate 21; a gap 22a is formed between two support rods 22. The panel is placed on the first carrier plate 21, with both sides of the panel overlapping the support rods 22 respectively. It should be noted that when the panel is placed on the first carrier plate 21, there is no need to make precise adjustments to its position; it is sufficient that the position is not too offset so that the first transfer component 4 cannot pick it up.

[0019] The first transfer assembly 4 is disposed above the first platform 2, and includes a first module 41 with a driving direction of X-axis, a second module 42 connected to the first module 41 with a driving direction of Y-axis, and a third module 43 connected to the second module 42 with a driving direction of Z-axis; the third module 43 is connected to a first rotating device 44 that drives rotation along the Z-axis, and the first rotating device 44 is connected to a second rotating device 45 that drives rotation along the Y-axis; the second rotating device 45 is connected to a suction cup assembly 46.

[0020] like Figure 7 As shown, clamping drive devices 47 are symmetrically connected to both sides of the suction cup assembly 46. Each clamping drive device 47 is connected to two symmetrical grippers 48. The grippers 48 are U-shaped and have openings 481. The grippers 48 extend into the gap 22a to pick up the panel. In the clamping state, the openings 481 of the two grippers 48 are connected to each other and their lower end faces together form a support surface 482.

[0021] In this embodiment, the suction cup assembly 46 moves to the first platform 2 through the coordinated adjustment of the first module 41, the second module 42, and the third module 43. When picking up the panel, the two grippers 48 are first driven by the clamping drive device 47 to merge and clamp the panel on both sides in the X direction. During the clamping process, the position of the panel is also initially adjusted so that the length direction of the panel is basically parallel to the Y direction. Then, the suction cup assembly 46 picks up the panel and fixes it in place.

[0022] Additionally, it should be noted that the gripper 48 not only assists in panel positioning but also supports the panel via the support surface 482 during a certain process, ensuring that the sides of the panel will not bend or be damaged due to excessive gravity. Before assembling with the back panel, the gripper 48 opens; after assembly, the suction cup assembly 46 detaches.

[0023] The pressing assembly 3 includes a second platform 31 and a pressure plate 32. The pressure plate 32 spans the second platform 31 and its two ends are connected to a first driving device 33 with a vertical driving direction. The first driving device 33 is connected to the machine base 1 through a second driving device 34 with a driving direction of X. The second platform 31 is provided with a contouring groove 31a formed by multiple fixing blocks 311, and the back plate is placed in the contouring groove 31a.

[0024] A vision device 5 is installed directly above the second platform 31, which can collect the position information of the back panel.

[0025] A light assembly 321 is provided on the upper surface of the pressure plate 32. When the pressure plate 32 is directly above the second carrier plate, a light source is formed by the light assembly 321, and the vision device 5 can collect the position information of the panel.

[0026] The operating principle of the assembly equipment in this embodiment is as follows: The back panel is placed on the second platform 31, and its position is positioned by the contour groove 31a. After placement, the position information of the back panel is collected by the vision device 5. The panel with the adhesive strip is placed face down on the first platform 2, and its two ends are respectively attached to the support rod 22. When the first transfer component 4 picks up the panel from the first platform 2, it first clamps the panel with the gripper 48, and then sucks up the panel surface with the suction cup component 46. Next, it moves upwards via the third module 43, and then the second drive device 34 drives the panel with the adhesive strip facing the operator, who then removes the protective film from the adhesive strip. Afterwards, the panel moves downwards with the adhesive strip facing down to directly above the second platform 31. During this process, the pressure plate 32 moves to directly below the panel under the drive of the second drive device 34, and the light component 321 illuminates the panel, enabling the vision device 5 to accurately acquire the panel's position information. After acquiring the panel's position information, the pressure plate 32 moves away from the second platform 31 under the drive of the second drive device 34. Based on the collected position information of the back panel and the front panel, the first transfer assembly 4 adjusts the position of the front panel; after adjustment, the front panel is driven downwards to assemble with the back panel. Before the front panel is assembled with the back panel downwards, the gripper 48 opens first; after assembly, the suction cup assembly 46 disengages from the front panel. The second drive device 34 drives the pressure plate 32 to move directly above the second platform 31. The first drive device 33 then drives the pressure plate 32 downwards, pressing the panel downwards through the protrusion 322, so that the panel and back panel are tightly fitted together and held under pressure for a period of time. The assembly of the panel and back panel is completed.
