Abstract
Description
Technical Field
[0001] This utility model relates to the field of automation equipment technology, and in particular to a flexible circuit board folding and attaching device. Background Technology
[0002] The screen has a flexible circuit board attached to one edge. The flexible circuit board is used for power supply and signal transmission. During the screen manufacturing process, the flexible circuit board needs to be folded to the back of the screen and fixed. Then the screen is assembled into the housing to reduce the space occupied by the flexible circuit board and make the screen have a narrow bezel.
[0003] Currently, the step of folding the flexible circuit board onto the back of the screen for fixation is mostly done manually, which is inefficient and difficult to guarantee quality. Therefore, there is a need for an automated device that can fold the flexible circuit board onto the back of the screen and fix it in order to improve production efficiency and quality. Utility Model Content
[0004] The purpose of this utility model is to provide a flexible circuit board folding and attaching device. The technical problem to be solved is how to provide a device that can automatically fold a flexible circuit board to the back of the screen and fix it.
[0005] To achieve the above objectives, the solution of this utility model is: a flexible circuit board folding and attaching device for folding and fixing a flexible circuit board on the screen to the back of the screen body, including an adhesive application platform, an adhesive application mechanism, a folding platform, a transfer robot, and a folding part;
[0006] The top surface of the adhesive mounting platform is used to support the screen body and make the back of the screen body face upwards, with the flexible circuit board connected to one side of the screen body.
[0007] The adhesive application mechanism includes an adhesive application bracket and an adhesive application displacement drive mechanism. The adhesive application bracket is equipped with an adhesive feeding roll, an adhesive take-up roll, and an adhesive application roller. The adhesive feeding roll has a strip wound around it, with multiple segments of double-sided adhesive applied to one side. These segments are arranged in an array along the strip's extension direction. The adhesive feeding roll releases the strip by rotation, and the adhesive take-up roll winds up the strip released by the feeding roll by rotation. The adhesive application roller is located below the feeding roll and the take-up roll. The strip between the feeding roll and the take-up roll passes under the adhesive application roller, with the side of the strip below the roller having the double-sided adhesive facing downwards. The adhesive application displacement drive mechanism drives the adhesive application bracket to move so that the adhesive application roller presses against the screen body on the top surface of the adhesive application platform, thus adhering the double-sided adhesive to the back of the screen body.
[0008] The transfer robot is used to transfer the screen on the adhesive application platform to the folding platform;
[0009] The top surface of the folding platform is used to support the screen body and make the back of the screen body face upward, with the flexible circuit board extending out from one side of the folding platform.
[0010] The folding part is rotated around a horizontally extending pivot, and a folding head is eccentrically positioned on the pivot. When the folding part is rotated, the folding head can be flipped to the side of the folding platform to support the flexible circuit board extending from the folding platform. The folding head can also be flipped to the top surface of the folding platform to fold and press the flexible circuit board supported by the folding head onto the back of the screen body, so that the flexible circuit board is attached to the double-sided adhesive on the back of the screen body.
[0011] Furthermore, the adhesive application platform is mounted on the adhesive application XXY alignment platform, which drives the adhesive application platform to move laterally and horizontally, as well as rotate horizontally, in order to adjust the relative position between the adhesive application platform and the adhesive application mechanism.
[0012] Furthermore, the top surface of the adhesive mounting platform is provided with vacuum holes for adsorbing and fixing the screen body.
[0013] Furthermore, the adhesive application displacement driving mechanism is at least used to drive the adhesive application bracket to rise and fall, and to move laterally along the rolling direction of the adhesive application roller.
[0014] Furthermore, the folding platform is mounted on the folding XXY alignment platform, which drives the folding platform to move laterally and horizontally, as well as rotate horizontally, in order to adjust the relative position between the folding platform and the folding part.
[0015] Furthermore, the folding part is L-shaped, and a folding motor is connected to one side of the L-shape. The folding motor drives the folding part to rotate around a shaft parallel to the other side of the L-shape, and the other side of the L-shape is the folding head.
[0016] Furthermore, the top surface of the folding platform is provided with vacuum holes for adsorbing and fixing the screen body.
[0017] Furthermore, the side of the folding head used to support the flexible circuit board is provided with vacuum holes for adsorbing and fixing the flexible circuit board.
[0018] The beneficial effects of this utility model after adopting the above solution are as follows: By placing the screen body on the adhesive application platform, the adhesive application roller presses down the material strip and rolls it over the back of the screen body to transfer the double-sided adhesive on the material strip to the back of the screen body. The screen with double-sided adhesive applied is transferred to the top surface of the folding platform by the transfer robot. The folding part is rotated around a horizontally extending pivot, and a folding head is eccentrically set on the pivot. When the folding part is rotated, the folding head can be flipped to the side of the folding platform to support the flexible circuit board extending from the folding platform. It can also be flipped to the top surface of the folding platform to fold and press the flexible circuit board supported by the folding head onto the back of the screen body, so that the flexible circuit board is attached to the double-sided adhesive on the back of the screen body, thereby realizing the automatic folding and fixing of the flexible circuit board to the back of the screen.

The adhesive application feed roll 11 has a strip wound around it, with multiple segments of double-sided adhesive applied to one side. These segments are arranged in an array along the strip's extension direction. The adhesive application feed roll 11 is used to release the strip by rotation, and the adhesive application take-up roll 12 is used to wind up the strip released by the adhesive application feed roll 11 by rotation. Both the adhesive application feed roll 11 and the adhesive application take-up roll 12 are driven by a motor to rotate (this is a conventional technique in the art and will not be described in detail in this embodiment). The adhesive roller 13 is located below the adhesive feeding roll 11 and the adhesive taking roll 12. The material strip between the adhesive feeding roll 11 and the adhesive taking roll 12 passes under the adhesive roller 13 and is tensioned and adhered to the material strip below the adhesive roller 13.
