It solves the problem in existing technologies where manual operation is susceptible to fatigue, operating habits, and other subjective factors, resulting in low assembly efficiency and unreliable assembly accuracy, thus increasing manufacturing costs for enterprises. Understandably, the aforementioned solutions can also be used to improve assembly efficiency and yield.

[0022] In this embodiment, the main assembly body 101 consists of a frame 102, an A-Cover (referring to the screen casing component of a laptop, monitor, television, etc.) loading and bonding conveyor belt 103, an A-Cover buffer conveyor belt 104, an LCD loading conveyor belt 105, an outer frame 106, an A-Cover positioning vision component 107, and a pressing and positioning vision component 108. The frame 102 provides stable support. The A-Cover loading and bonding conveyor belt, the A-Cover buffer conveyor belt 104, and the LCD loading conveyor belt 105 are used to transport the product to the designated position. The outer frame 106 is equipped with... The assembly assembly is placed on the frame 102 and installed inside the outer frame 106, which protects the assembly assembly. The A-Cover positioning vision component 107 is installed inside the outer frame 106 and is used for positioning when the LCD screen is attached to the housing component. The pressing positioning vision component 108 is used for positioning when the LCD screen is pressed against the housing component. Through the assembly assembly, the automatic assembly of the screen and the housing component can be realized, which solves the problem that the existing technology is prone to low assembly efficiency and cannot guarantee assembly accuracy due to subjective factors such as fatigue and operating habits of manual operation, which increases the manufacturing cost of enterprises.

[0023] The bonding adjustment frame 109 is installed inside the main assembly body 101, the bonding lifting seat 110 is installed on the bonding adjustment frame 109, the vacuum flat plate suction 111 is connected to the bonding lifting seat 110 through the rotating and flipping component, the rotating and flipping component is installed on the bonding lifting seat 110 and supports the vacuum flat plate suction 111, and the pressing component is installed inside the main assembly body 101. The bonding adjustment frame 109 consists of an X-axis moving component, a Y-axis moving component, and a Z-axis moving component, which can control the bonding lifting seat 110 to move in the X, Y, and Z directions. The bonding lifting seat 110 is connected to the Z-axis moving component, which allows for vertical movement. The vacuum flat plate suction 111 is connected to the bonding lifting seat 110 through the rotating and flipping component. The vacuum flat plate suction 111 is used to pick up LCD screen modules, and the pressing component is used to press the bonded LCD screen modules onto the main assembly body 101. The LCD screen module and the outer casing are pressed and held under pressure. The LCD screen module and the outer casing are automatically transported to the designated position via the corresponding feed conveyor belt. Combined with visual guidance and positioning, the vacuum plate suction 111 picks up the LCD screen module. After the outer casing is transported to the assembly position, the suction cup at the bottom of the main assembly machine 101 flattens the outer casing. The vacuum plate suction 111 moves the LCD screen module above the outer casing, 1cm above it. Under the condition of meeting the bonding requirements, the Z-axis moving component on the bonding adjustment frame 109 moves downward, causing the vacuum plate suction 111 to move the LCD screen module downward and bond it with the outer casing. Afterward, the vacuum plate suction 111 performs back-blowing to ensure that the LCD screen module can be detached normally. After the LCD screen module and the outer casing are bonded, the product automatically flows into the pressing station for pressing and holds pressure for 6 seconds. After holding pressure, it automatically flows out. This solution, by enhancing automation, increases the yield rate from 73% to 99.8% with manual operation. It solves the problem that existing technologies suffer from low assembly efficiency and inability to guarantee assembly accuracy due to subjective factors such as fatigue and operating habits that affect manual operation, thus increasing the manufacturing cost for enterprises.

The four positioning cameras 117 are used to collect the position information of the four corners of the LCD screen module and the edge information of the outer shell component. Combined with image processing, the fitting adjustment frame 109 is guided to adjust so that the vacuum flat plate suction 111 can accurately pick up the LCD screen module. Through the positioning cameras 117, the accurate movement of the vacuum flat plate suction 111 can be guaranteed.

[0026] Meanwhile, the pressing adjustment frame 118 is fixedly connected to the main assembly body 101 and located on the side of the main assembly body 101 near the bonding adjustment frame 109. The pressing lifting seat 119 is mounted on the pressing adjustment frame 118. The pressing head 123 is connected to the pressing lifting seat 119 through the mounting part. The mounting part is mounted on the pressing lifting seat 119 and supports the pressing head 123. The pressing adjustment frame 118 operates on the same principle as the bonding adjustment frame 109, and can also drive the pressing lifting seat 119 to move in an X-shape. The pressing and lifting seat 119 is connected to the Z-axis moving component, allowing vertical movement in the three directions of Y, Z, and H. There are two pressing heads 123, which are connected to the pressing and lifting seat 119 via the mounting part. These heads are used to press the LCD screen module and the housing component together. The pressing heads 123 can rotate, and by controlling their movement, the pressing and pressure holding of the LCD screen module and the housing component can be achieved.

The pressing head 123 is installed at the bottom of the mounting plate 122. The mounting plate 122 is also provided with a spacing adjustment component, which can adjust the spacing of the pressing head 123 to improve the adaptability of the pressing head 123. By moving the pressing head 123 downward, the pressing and pressure holding of the LCD screen module and the housing component can be realized.

[0028] Finally, the pressure sensor is fixedly connected to the pressing lifting seat 119 and is located on the side of the pressing lifting seat 119 close to the mounting bracket 120. The pressure sensor 124 can contact the mounting bracket 120. Through the pressure sensor 124, precise pressure control is ensured in the pressure holding stage.

[0029] In this embodiment, the application employs a high-precision ball screw module paired with a high-speed servo motor, and adopts a multi-module linkage gantry architecture. This improves assembly efficiency while enabling XY and rotational adjustments. Combined with a high-precision vision system, it simultaneously performs high-precision imaging of the four corners of the display screen, using image algorithms to calculate the offset of the four corners in real time and dynamically adjust them, thereby achieving high-precision alignment and bonding of the screen. In use, the LCD screen module and housing components are automatically transported to the designated position via corresponding feed conveyors. The vacuum flat plate suction 111, combined with visual guidance positioning, picks up the LCD screen module. After the housing components are transported to the assembly position, they are flattened by suction cups at the bottom of the main assembly machine body 101. The vacuum flat plate suction 111 then moves the LCD screen module above the housing components, 1cm above them. Under the condition of satisfactory bonding, the Z-axis moving component on the bonding adjustment frame 109 moves downwards, allowing the vacuum flat plate suction 111 to... A vacuum plate suction unit 111 moves the LCD screen module downwards to fit against the outer casing component. Then, the vacuum plate suction unit 111 performs a backflushing process to ensure the LCD screen module can detach properly. After the LCD screen module and outer casing component are fitted together, the product automatically flows into the pressing station for pressing. The pressing adjustment frame 118 adjusts the position of the pressing head 123. After adjusting the pressing head 123 to the accurate position, it is controlled to move downwards, pressing the LCD screen module and outer casing component together and holding the pressure for 6 seconds. After the pressure holding is completed, the product automatically flows out. This solution, while improving automation, increases the yield rate from 73% with manual operation to 99.8%. It solves the problem that existing technologies suffer from low assembly efficiency and inconsistent assembly accuracy due to subjective factors such as fatigue and operating habits during manual operation, which increases manufacturing costs for enterprises.
