Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing equipment technology, and in particular to a flexible circuit bending fixture. Background Technology

[0002] Bending is a common process in the manufacturing of flexible printed circuit boards (FPCBs). Traditional FPCB bending fixtures typically suffer from the following shortcomings: first, low positioning accuracy leads to significant deviations in the bending angle, affecting product quality; second, unreasonable structural design makes it difficult to adapt to the bending requirements of flexible circuits of different specifications, resulting in poor versatility; third, low automation requires manual assistance, leading to low production efficiency; and fourth, poor yield, as the flexible circuits are easily damaged by compression during bending. Therefore, to address the shortcomings of existing technologies, there is an urgent need to design a flexible circuit bending fixture that is accurate in positioning, highly adaptable, and highly automated.

[0003] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a flexible circuit bending fixture to solve the above problems. Utility Model Content

[0004] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a flexible circuit bending fixture to achieve precise positioning and safe bending of flexible circuits, thereby improving product processing accuracy, production efficiency and product quality.

[0005] To achieve the above and other related objectives, the technical solution provided by this utility model is: a flexible circuit bending fixture, comprising:

[0006] Base;

[0007] The lower mold is fixed on the left side of the base;

[0008] The upper mold is located on the right side of the base and its movement in all directions is controlled by a drive assembly.

[0009] The upper mold and the lower mold cooperate to achieve bending of the flexible circuit.

[0010] A preferred technical solution is as follows: it further includes a clamping block, which is located on the base near the right side of the upper mold. The clamping block is driven up and down by a clamping cylinder and is used to cooperate with the base to clamp one end of the flexible circuit.

[0011] The preferred technical solution is as follows: the driving component consists of a vertical transfer module and a horizontal transfer module. The vertical transfer module is fixed on the base and is used to drive the horizontal transfer module to move up and down. The horizontal transfer module is used to drive the upper mold to move left and right.

[0012] The preferred technical solution is that the lower mold is fixedly installed to the base by bolts and is configured to be able to adjust its installation position on the base in the left and right directions.

[0013] The preferred technical solution is that both the upper mold and the lower mold are made of block-shaped rubber material.

[0014] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0015] This utility model provides a flexible circuit bending fixture. By setting a clamping block driven by a clamping cylinder, it can automatically clamp one end of the flexible circuit, preventing circuit displacement during bending and improving positioning accuracy. The drive component adopts a combination of vertical transfer module and horizontal transfer module, which can precisely control the up, down, left, and right movement of the upper die to achieve accurate bending of the flexible circuit and avoid damage to the flexible circuit due to compression during bending. The lower die is installed by bolts and can be adjusted left and right to adapt to the bending requirements of flexible circuits of different specifications, improving the versatility of the fixture. The upper and lower dies are made of rubber material, which can avoid scratching the surface of the flexible circuit. At the same time, the elastic cushioning effect of rubber makes the bending process smoother and improves product yield. Attached Figure Description

[0022] Base 1;

[0023] Lower mold 2 is fixed on the left side of base 1;

[0024] Upper mold 3 is located on the right side of base 1 and its up, down, left and right movements are controlled by drive component 4;

[0025] The upper mold 3 and the lower mold 2 work together to bend the flexible circuit.

[0026] like Figure 1 As shown, in an exemplary embodiment of this utility model, a clamping block 5 is also included. The clamping block 5 is located on the right side of the base 1 near the upper mold. The clamping block 5 is driven up and down by the clamping cylinder 6 and is used to cooperate with the base 1 to clamp one end of the flexible line.

[0027] like Figure 1 As shown, in an exemplary embodiment of this utility model, the driving component 4 consists of a vertical transfer module 41 and a horizontal transfer module 42. The vertical transfer module 41 is fixed on the base 1 and is used to drive the horizontal transfer module 42 to move up and down. The horizontal transfer module 42 is used to drive the upper mold 3 to move left and right.

[0030] In use, first place one end of the flexible circuit on the base 1 and press it with the pressing block 5 driven by the pressing cylinder 6. Then, control the upper mold 3 to press down through the vertical transfer module 41. Note that at this time, it is not necessary to control the upper mold 3 to press the flexible circuit onto the base 1, but to press the flexible circuit onto the base 1 as much as possible while ensuring that the space between the upper mold 3 and the base 1 is sufficient for the flexible circuit to move. Next, control the upper mold 3 to move to the left through the horizontal transfer mechanism 42. Note that at this time, it is not necessary to control the upper mold 3 to press the flexible circuit onto the side wall of the lower mold 2, but to press the flexible circuit onto the side wall of the lower mold 2 as much as possible while ensuring that the space between the upper mold 3 and the side wall of the lower mold 2 is sufficient for the flexible circuit to move. Then, control the vertical transfer module 41 and the horizontal transfer module 42 simultaneously to drive the upper mold 3 to move along the lower left corner until the lower left corner of the upper mold 3 fits into the angle structure formed by the lower mold 2 and the base 1, thereby bending the flexible circuit.

[0031] Therefore, this utility model has the following advantages:

[0032] This utility model provides a flexible circuit bending fixture. By setting a clamping block driven by a clamping cylinder, it can automatically clamp one end of the flexible circuit, preventing circuit displacement during bending and improving positioning accuracy. The drive component adopts a combination of vertical transfer module and horizontal transfer module, which can precisely control the up, down, left, and right movement of the upper die to achieve accurate bending of the flexible circuit and avoid damage to the flexible circuit due to compression during bending. The lower die is installed by bolts and can be adjusted left and right to adapt to the bending requirements of flexible circuits of different specifications, improving the versatility of the fixture. The upper and lower dies are made of rubber material, which can avoid scratching the surface of the flexible circuit. At the same time, the elastic cushioning effect of rubber makes the bending process smoother and improves product yield.
