[0016] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0017] The utility model discloses a display screen and touch screen assembly machine, combined with Figures 1 to 3 As shown, it includes a machine platform 1, on which a display screen conveying mechanism 2 and a touch screen conveying mechanism 3 are provided, on which an assembly station is provided, on which a display screen visual inspection mechanism 4 arranged adjacent to the assembly station is provided, and the display screen visual inspection mechanism 4 is used to photograph the display screen on the assembly station, and a touch screen visual guidance mechanism 5 and a touch screen conveying mechanism 6 are provided adjacent to the end of the touch screen conveying mechanism 3, and the touch screen visual guidance mechanism 5 is used to photograph the touch screen conveyed to the end of the touch screen conveying mechanism 3, and the touch screen conveying mechanism 6 is used to pick up the touch screen from the end of the touch screen conveying mechanism 3 and place it on a preset film tearing platform 10, and a film tearing mechanism 7 for tearing off the release film on the surface of the touch screen is provided adjacent to the film tearing platform 10, and a touch screen visual inspection platform 8 and an XYZ axis conveying mechanism 9 are provided adjacent to the film tearing mechanism 7, and the XYZ axis conveying mechanism 9 is used to pick up the touch screen after film tearing from the film tearing mechanism 7 and place it on the touch screen visual inspection platform 8 for inspection, and to pick up the inspected touch screen from the touch screen visual inspection platform 8 and assemble it on the display screen of the assembly station.

[0018] In the above structure, the display screen conveying mechanism 2 and the touch screen conveying mechanism 3 are arranged side by side on the machine 1, the display screen conveying mechanism 2 is used to convey the LCD display screen, and the touch screen conveying mechanism 3 is used to convey the touch screen, wherein the LCD display screen that has not been assembled is suspended and waits for assembly when it is conveyed to the assembly station, and at the same time, the display screen visual inspection mechanism 4 is used to perform visual inspection on the LCD display screen on the assembly station to measure the position, angle, size and other information of the LCD display screen to facilitate the subsequent precise assembly of the touch screen. Correspondingly, the touch screen is transported by the touch screen conveying mechanism 3, and the touch screen visual guidance mechanism 5 is used at its end to detect the position, angle, size and other information of the touch screen. Based on these parameter information, the touch screen conveying mechanism 6 helps to accurately pick up the touch screen from the end of the touch screen conveying mechanism 3 and place it on the preset film-tearing platform 10. After the film-tearing mechanism 7 tears off the release film on the surface of the touch screen, the XYZ axis conveying mechanism 9 is used to pick up the film-tearing touch screen from the film-tearing mechanism 7, and then the touch screen is placed on the touch screen visual inspection platform 8 for posture detection before assembly. Finally, the XYZ axis conveying mechanism 9 picks up the detected touch screen, and according to the detection information of the display screen visual inspection mechanism 4 and the touch screen visual inspection platform 8, the touch screen is aligned and assembled on the display screen of the assembly station. Compared with the prior art, the utility model assists the assembly of the display screen and the touch screen by means of visual guidance and visual alignment, which not only improves the product assembly accuracy, but also greatly saves labor costs and better meets the process requirements.

[0019] As a preferred embodiment, the display screen conveying mechanism 2 and the touch screen conveying mechanism 3 are arranged in parallel. Further, the length of the display screen conveying mechanism 2 is greater than the length of the touch screen conveying mechanism 3.

[0020] In the above structure, see Figure 2 The display screen conveying mechanism 2 and the touch screen conveying mechanism 3 have different lengths. The conveying length of the display screen conveying mechanism 2 is relatively long. When the unassembled LCD display screen is delivered to the assembly station, it needs to pause at the assembly station to wait for assembly. For the front end of the conveying mechanism, the front ends of the display screen conveying mechanism 2 and the touch screen conveying mechanism 3 are aligned. This structure is beneficial for the staff to place the LCD display screen and the touch screen on the display screen conveying mechanism 2 and the touch screen conveying mechanism 3 respectively.

[0021] As a preferred method, see Figure 2, an operation area 11 is provided on the machine 1 at the end of the touch screen conveying mechanism 3, and the touch screen visual guidance mechanism 5, the touch screen conveying mechanism 6, the film tearing mechanism 7, the touch screen visual detection platform 8, the XYZ axis conveying mechanism 9 and the film tearing platform 10 are all located in the operation area 11. Among them, because the conveying distance of the touch screen conveying mechanism 3 in this embodiment is relatively short, an operation area 11 will be left at its end position. In this embodiment, the touch screen visual guidance mechanism 5, the touch screen conveying mechanism 6, the film tearing mechanism 7, the touch screen visual detection platform 8, the XYZ axis conveying mechanism 9 and the film tearing platform 10 are preferably concentrated in the operation area 11, which not only realizes the rational use of space, but also facilitates wiring and motion path planning, and can make the overall structure of the equipment more compact.

[0022] In this embodiment, the display screen visual detection mechanism 4, the touch screen visual guidance mechanism 5 and the touch screen visual detection platform 8 are all CCD visual mechanisms. Accordingly, a computer and other core computing and processing devices can be set in the cabinet under the machine 1. These core computing and processing devices can be used to analyze and process the image information collected by the display screen visual detection mechanism 4, the touch screen visual guidance mechanism 5 and the touch screen visual detection platform 8, so as to obtain the position, angle, size and other information of the display screen and the touch screen. At the same time, these core computing and processing devices can also be used to coordinate and control the motion mechanisms such as the touch screen conveying mechanism 6, the film tearing mechanism 7, and the XYZ axis conveying mechanism 9.

[0023] As a preferred embodiment, the film-tearing platform 10 is a heatable platform. Specifically, the film-tearing platform 10 heats the touch screen on the film-tearing platform 10 by electric heating, which helps the film-tearing mechanism 7 to quickly tear off the release film on the touch screen surface.

[0024] On this basis, the present embodiment includes a cabinet 12, and the cabinet 12 is arranged above the machine 1. The cabinet 12 mainly plays a protective role such as dust prevention, and the cabinet 12 can be provided with components such as an observation window and a switch door.

[0025] Specifically, the display screen conveying mechanism 2 and the touch screen conveying mechanism 3 can pass through the cabinet 12 and extend outward.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
