Description

Folding jig

The invention relates to a jig, and particularly to a folding jig.

With the development of technology and the change of consumers' usage habits, electronic products that are thin and thin and can be carried around have become the current mainstream of consumption. As a result, the space available for electronic components inside electronic products is continuously reduced. In order to complete the electrical connection between electronic components in a limited space, it has the characteristics of high wiring density, light weight, thin thickness, and flexibility. Circuit boards are widely used.

In order to effectively use the space inside the electronic product, before placing the flexible circuit board into the electronic product, it is usually necessary to perform a pre-folding procedure on the flexible circuit board, but the pre-folded flexible circuit board may spring back, or due to pre-folding The applied force is too large to cause circuit damage or substrate cracking at the pre-folding point of the flexible circuit board, so that the yield of the production process cannot be significantly improved.

The invention provides a folding jig, which helps to improve the yield of the manufacturing process.

The folding jig of the invention includes a base, two movable parts, a traction part, a platform and a lowering part. The two movable parts are pivotally connected to the base. The traction member is disposed above the base, wherein opposite ends of the traction member are connected to the two movable members respectively. The platform is set on the base and is located between the two movable parts. The platform has a groove, wherein the platform is used to carry a flexible circuit board, and the flexible circuit board covers the groove. The pressing member includes a first pressing rod and a second pressing rod arranged side by side, wherein the first pressing rod and the second pressing rod are movably arranged above the base and directly facing the groove. During the downward movement of the first depressing rod and the second depressing rod, the first depressing rod presses against the flexible circuit board placed on the platform, and drives the flexible circuit board to partially move into the groove. The second depressing rod presses against the traction member, so that the traction member drives the two movable members to rotate relative to the base in two different rotation directions, respectively. The two movable parts are pushed against the opposite sides of the flexible circuit board, so that the opposite sides of the flexible circuit board abut on the platform.

Based on the above, the folding jig of the present invention can be used to assist the operator to quickly and accurately fold the flexible circuit board, and can prevent the flexible circuit board from being excessively bent to cause circuit damage or substrate cracking, which helps to improve the process quality rate.
