[0035] In the process of assembling the screen D1 to the mid-frame M1, the wire D11 of the screen D1 needs to be passed through the wire hole M11 of the mid-frame M1, and then the screen D1 is installed to the mid-frame M1. Since there is no FPC wire perforation process in the prior art, the manual operation of the FPC wire perforation has a very high failure rate, and the screen D1 is easily contaminated.

[0036] To this end, please refer to Figures 1 to 11 The present application discloses a screen assembly device. The screen assembly device comprises a screen positioning jig 1, a mid-frame positioning jig 2, a horizontal driving assembly 3, a visual positioning assembly 4, a picking assembly 5, a lifting driving assembly 6, a wire arranging assembly 7 and a wire clamping assembly 8.

[0037] The screen positioning jig 1 and the mid-frame positioning jig 2 are installed at the output end of the horizontal driving assembly 3.

[0038] The visual positioning assembly 4 is used for visual positioning of the screen D1 on the screen positioning jig 1 and the middle frame M1 on the middle frame positioning jig 2 located below. After the screen D1 located at the assembling position (the position of the screen D1 when it is ready to be lifted) is lifted, the horizontal driving assembly 3 drives the middle frame M1 to move to the assembling position based on the positioning information of the visual positioning assembly 4, so that the screen D1 can be assembled to the middle frame M1 vertically downward when assembling. Through the arrangement of the visual positioning assembly 4, the screen D1 and the middle frame M1 can be accurately positioned, which is beneficial to the accurate assembly of the screen D1, the middle frame M1, the flat cable D11 and the flat cable hole M11.

[0039] The picking assembly 5 is used for picking the screen D1 on the screen positioning jig 1.

[0040] The visual positioning assembly 4 and the picking assembly 5 are installed at the output end of the lifting driving assembly 6, and the lifting driving assembly 6 is used for driving the visual positioning assembly 4 and the picking assembly 5 to move up and down, so that the picking assembly 5 picks and lifts the screen D1 located below.

[0041] The wire arranging assembly 7 is used for arranging the flat cable D11 connected to the screen D1 in the lifting position, so that the flat cable D11 is in a vertical state.

[0042] The wire clamping assembly 8 includes a wire clamping lifting mechanism 81 and a wire clamping mechanism 82, and the wire clamping mechanism 82 is installed at the output end of the wire clamping lifting mechanism 81. The wire clamping mechanism 82 is used for clamping the flat cable D11 after being arranged. It can be understood that in order to maintain the state of the flat cable D11, the wire arranging assembly 7 does not exit the limitation on the flat cable D11 until the wire clamping mechanism 82 clamps the flat cable D11.

[0043] After the wire clamping mechanism 82 clamps the flat cable D11, the lifting driving assembly 6 drives the picking assembly 5 to descend, and the wire clamping lifting mechanism 81 drives the wire clamping mechanism 82 to descend synchronously, so that the screen D1 is assembled on the middle frame M1, and the flat cable D11 is inserted into the flat cable hole M11 on the middle frame M1. After the wire arranging assembly 7 arranges the flat cable D11 into a vertical state, the wire clamping mechanism 82 is used for clamping the flat cable D11, and then through the synchronous descent of the picking assembly 5 and the wire clamping mechanism 82, the screen D1 can be assembled on the middle frame M1, and the flat cable D11 can be inserted into the flat cable hole M11 on the middle frame M1.

[0044] In the embodiment of the application, the screen assembling device comprises a horizontal driving assembly 3, a screen positioning jig 1 and a middle frame positioning jig 2 installed at the output end of the horizontal driving assembly 3, a visual positioning assembly 4, a picking assembly 5, a lifting driving assembly 6, a wire arranging assembly 7 and a wire clamping assembly 8. The screen D1 and the middle frame M1 are positioned by the visual positioning assembly 4. After the screen D1 at the assembling position is lifted, the horizontal driving assembly 3 drives the middle frame M1 to move to the assembling position based on the positioning information of the visual positioning assembly 4. The visual positioning assembly 4 and the picking assembly 5 are installed at the output end of the lifting driving assembly 6. The lifting driving assembly 6 is used to drive the visual positioning assembly 4 and the picking assembly 5 to move up and down, so that the picking assembly 5 picks up and lifts the screen D1 below it. The wire arranging assembly 7 is used to arrange the wire D11 connected to the screen D1 at the lifting position, so that the wire D11 is in a vertical and downward state. The wire clamping assembly 8 comprises a wire clamping lifting mechanism 81 and a wire clamping mechanism 82. The wire clamping mechanism 82 is installed at the output end of the wire clamping lifting mechanism 81. The wire clamping mechanism 82 is used to clamp the wire D11 after arrangement. After the wire D11 is clamped by the wire clamping mechanism 82, the lifting driving assembly 6 drives the picking assembly 5 to descend, and the wire clamping lifting mechanism 81 drives the wire clamping mechanism 82 to synchronously descend, so that the screen D1 is assembled on the middle frame M1, and the wire D11 penetrates into the wire hole M11 on the middle frame M1. Therefore, when the screen D1 and the middle frame M1 are assembled by the screen assembling device, the wire D11 connected to the screen D1 can be simultaneously penetrated into the wire hole M11 on the middle frame M1, and the problems of difficult operation, low efficiency and pollution of the screen D1 when the wire D11 is manually perforated are solved.

After screen D1 is lifted, horizontal driving assembly 3 drives middle frame M1 to move to the assembly position where screen D1 was originally located.

[0080] S5, each push rod 71 is driven by push rod driving assembly 72 to push corresponding wire D11 to a vertical downward state, then each claw 823 is driven by horizontal sliding table air cylinder 83 to adjust the position, and is driven by claw air cylinder 822 to clamp wire D11 of screen D1, so that each wire D11 remains in a vertical downward state.

[0081] S6, CCD camera 411 respectively acquires screen diagonal points and middle frame diagonal points to determine whether the center and angle of screen D1 and middle frame M1 coincide, and when it is confirmed that they coincide, the next operation can be performed, otherwise, adjustment is made based on rotating motor 101 and / or horizontal driving assembly 3.

[0082] S7, lifting driving assembly 6 drives pickup assembly 5 to move downward, and clamp wire lifting mechanism 81 drives clamp wire mechanism 82 to move downward synchronously, so that screen D1 is assembled on middle frame M1, and wire D11 passes through wire hole M11 on middle frame M1. In this process, pressure sensor 1041 detects whether the pressure between screen D1 and middle frame M1 exceeds a preset value in real time, and when wire D11 of screen D1 passes through wire hole M11 of middle frame M1, clamp wire assembly 8 exits the assembly process.

[0083] In actual operation, it is difficult for wire D11 to pass through wire hole M11, and the screen assembly device of the application can ensure that wire D11 passes through wire hole M11 by using the following steps:

[0084] At the beginning, the claw 823 clamps the end of the flat cable D11, and the claw 823 descends with the pickup assembly 5 to make the end of the flat cable D11 pass through the flat cable hole M11.

[0085] After the end of the flat cable D11 passes through the flat cable hole M11, the claw 823 moves upward and clamps the middle of the flat cable D11, and the claw 823 descends with the pickup assembly 5 to make the middle of the flat cable D11 pass through the flat cable hole M11.

[0086] After the middle of the flat cable D11 passes through the flat cable hole M11, the claw 823 moves upward and clamps the end of the flat cable D11 close to the screen D1, and the claw 823 descends with the pickup assembly 5 to finally make the flat cable D11 pass through the flat cable hole M11.

[0087] S8, each assembly resets, and the assembled screen D1 is taken out.

[0088] The above only discloses the preferred embodiments of the present application, and of course cannot limit the scope of the present application. Therefore, equivalent changes made within the scope of the patent application of the present application are still within the scope of the present application.
