AI Technical Summary

Technical Problem

During the downward process of the existing flexible circuit board pressing device, due to the excessive adhesion between the intermediate plate and the upper pressing plate, the intermediate plate falls from the upper pressing plate when the lower pressing plate drops to halfway, which poses safety risks and damages the flexible circuit board.

Method used

A fast pressure device is designed, including a support frame, a fast pressure combination plate and a driving mechanism. The fast-pressure combination plate consists of an upper pressing combo plate, an intermediate slide plate and a lower pressing combo plate. The intermediate slide plate is equipped with an elastic member. The elastic force of the elastic member causes the intermediate slide plate to fall simultaneously when the lower pressing combo plate falls, avoiding sudden drop caused by stickiness.

Benefits of technology

It effectively prevents the intermediate plate from falling suddenly during the downward pressure combo, reduces safety risks and protects the integrity of the flexible circuit board. At the same time, a card slot is installed to facilitate the installation and maintenance of the heating plate.

Description

Technical Field

[0001] The utility model belongs to the technical field of flexible circuit board processing equipment, in particular to a fast pressing device for a flexible circuit board. Background Art

[0002] Flexible circuit boards are made of polyimide or polyester film as a substrate, and are highly reliable and extremely flexible printed circuit boards. They have the characteristics of high wiring density, light weight, thin thickness, and good bendability.

[0003] In the flexible circuit board, it is necessary to heat it during pressing to increase the stability between the layers of the circuit board. In the existing pressing device for the flexible circuit board, after the pressing of the flexible circuit board is completed, the main problem is that the middle plate is pushed up by the lower plate during the rising process, and it descends completely by gravity. When the middle plate is tightly attached to the upper pressing plate, the lower closing plate will fall off the upper closing plate suddenly when it is halfway down, which is dangerous and also causes damage to the flexible circuit board. Utility Model Content

[0004] The purpose of the utility model is to provide a fast pressing device for flexible circuit boards, so as to overcome the defect that when the upper pressing plate is tightly adhered, the middle plate suddenly falls off the upper pressing plate when the lower pressing plate is halfway down, which causes danger. The specific technical solution is as follows:

[0006] A support frame, the support frame comprising operation windows penetrating the front and rear, and slide grooves are provided on the left and right sides of the operation window;

[0007] A quick pressing assembly plate is arranged in the operation window, and the quick pressing assembly plate comprises an upper pressing plate, an intermediate slide plate and a lower pressing plate; the upper pressing plate is fixed to the top of the support frame, the intermediate slide plate is clamped between the upper pressing plate and the lower pressing plate and can slide in the direction of the upper pressing plate, an elastic member extending in the direction of the upper pressing plate is arranged on one side of the intermediate slide plate, and the elastic member can move in the slide groove as the intermediate slide plate moves up and down; a baffle corresponding to the elastic member is arranged on one side of the upper pressing plate;

[0008] The driving mechanism is provided with the lower pressing plate at the top of the driving mechanism.

[0009] Preferably, the bottom surface of the upper pressing plate, the bottom surface and the top surface of the middle sliding plate, and both sides of the top surface of the lower pressing plate are provided with slots, and the heating plate is plugged into the slots.

[0010] Preferably, a handle is provided on the outer side of each heating plate.

[0011] Preferably, guide wheels are provided on both sides of the right end of the middle slide plate, and each guide wheel abuts against two sides of the slide groove.

[0012] Preferably, limit blocks corresponding to the guide wheel are respectively provided on both sides of the slide groove, and the limit blocks are located below the guide wheel.

[0013] Preferably, the elastic member includes a right-angle fixing plate, a fixing column and a compression spring; the first end of the right-angle fixing plate is fixed to the side of the middle slide plate, the second end of the right-angle fixing plate is fixed with the fixing column, one end of the compression spring is inserted into the fixing column and fixedly connected to the fixing column, and the other end is arranged pointing to the baffle.

The driving mechanism 9 adopts a hydraulic cylinder, and a hydraulic platform 12 is provided on the hydraulic cylinder. The hydraulic platform 12 abuts against the bottom of the lower pressing plate 6. During the pressing process, before starting the hydraulic cylinder, the flexible circuit board 100 to be pressed is placed on the lower first layer 10, and then the hydraulic cylinder is started. The hydraulic platform 12 of the hydraulic cylinder pushes the lower pressing plate 6 to move upward until it touches the middle slide 5. At this time, the bottom surface of the middle slide 5 and the lower pressing plate 6 press the flexible circuit board 100 on the first layer 10; as the hydraulic cylinder continues to rise, it continues to push the middle slide 5 upward until the middle slide 5 is in contact with the upper pressing plate 4. When the upper pressing plate 4 is pressed together with the middle slide plate 5, the bottom surface of the upper pressing plate 4 and the middle slide plate 5 press the flexible circuit board 100 on the second layer 11 to complete the pressing of the first layer 10 flexible circuit board 100 and the second layer 11 second flexible circuit board 100; after the pressing is completed, the hydraulic cylinder is started to move downward, and the lower pressing plate 6 moves downward accordingly. Under the action of the elastic member 7, the middle slide plate 5 will not stick to the upper pressing plate 4, but the middle slide plate 5 slides downward together with the lower pressing plate 6 until the clamping point of the middle slide plate 5 clamps it and stops it from moving downward, and the lower pressing plate 6 continues to move downward with the descent of the hydraulic cylinder, thereby realizing the separation of the upper pressing plate 4, the middle slide plate 5 and the lower pressing plate 6. After the separation is completed, the pressed flexible circuit board 100 can be taken out from the first layer 10 and the second layer 11.

[0036] As a preferred embodiment, the bottom surface of the upper pressing plate 4, the bottom surface and the top surface of the middle sliding plate 5, and the top surface of the lower pressing plate 6 are all detachably connected with the heating plate 13.

[0043] It can be understood that each guide wheel 19 is provided with a corresponding mounting seat 21 to improve the stability of the installation of the guide wheel 19 . The two guide wheels 19 have a guiding effect on the sliding of the middle slide 5 , which helps the middle slide 5 to slide on the operating window 2 .
