Flexible circuit boards made of flexible copper clad laminates have high wiring density, light weight, thin thickness, and bendability. Good characteristics, so it is applied to the field of electronic products. With the advancement of technology, people's requirements for it are gradually increasing. For example, in order to ensure the stability and flatness of the patch devices mounted on the flexible circuit board, It is necessary to install a reinforcing steel sheet that can improve local rigidity on the other side of the flexible circuit board opposite to this type of patch device.

However, in actual production, the mounting and fixing of the reinforced steel sheet on the flexible circuit board is completed by separate processing equipment, and the process flow is roughly as follows:

1. Lay the flexible circuit board to be mounted with reinforced steel sheet on the flat bearing platform first.

2. Manually or using an independently installed placement machine, the reinforcing steel sheet is peeled off from the adhesive film and placed on the set position on the flexible circuit board.

3. Then transfer the flexible circuit board pasted with the reinforced steel sheet on the carrier of the heating equipment and send it into the heating channel for heating.

4. After the flexible circuit board attached with the reinforcing steel sheet is heated to the design temperature, it is then transferred to the press, and after hot pressing, the reinforcing steel sheet is finally fixed on the flexible circuit board.

The shortcoming that above-mentioned method exists is:

1. Manual feeding, retrieving and pressing lead to low production efficiency.

2. A lot of labor is required, resulting in high labor costs.

3. Manual placement of reinforced steel sheets is prone to large placement position errors, resulting in low placement quality.

4. The bearing platform and the press machine on which the reinforced steel sheet is pasted are separate devices, which occupy a large area and require a large investment in equipment.

1. Patch position 1

The main function of this station is to adhere the reinforced steel sheet to the set position on the raw material flexible circuit board to form a semi-finished flexible circuit board (the raw material flexible circuit board refers to the flexible circuit board without the reinforced steel sheet, and the semi-finished flexible circuit board refers to the The flexible circuit board pasted with the reinforced steel sheet, the finished flexible circuit board refers to the flexible circuit board on the semi-finished flexible circuit board after the reinforced steel sheet is fixed by heat pressing, the same below), and its process equipment is set as follows:

1) Automatic stripping machine (also known as feeding feeder, not shown in the figure), which is suspended on the front end of the frame 6, and its function is to strip the reinforcing steel sheet from the carrier belt and place it on the black special Long (Chinese name: polytetrafluoroethylene, English full name is Polytetrafluoroethylene, referred to as Teflon, PTFE, F4, etc.)

2) The platform device 5 (the specific structure will be described later, see Figures 7, 8, 9, and 10), which is used to receive the raw material flexible circuit board, and the raw material flexible circuit board is precisely positioned on the top of the platform device 5 in a flat suction method. On the surface.

3) Placement machine 11 (see Fig. 1), installed on the top of machine base 6, is a conventional automatic placement equipment, which is mainly designed to absorb and paste the reinforced steel sheet on the material preparation board on the raw material flexible circuit board Location.

After the operation of pasting the reinforcing steel sheet on the raw material flexible circuit board is completed, the platform device 5 will be rotated and transferred to the hot pressing position 3 .

The main function of this station is to transfer the platform device 5 carrying the semi-finished flexible circuit board at the placement position 1 to the hot-pressing position 3 through the rotary machine 21, and at the same time, transfer the raw material flexible circuit board at the hot-pressing position 3 Another platform device 5 is also switched to the patch position 1 through the rotary machine 21. The number of platform devices 5 depends on the installation orientation of the all-in-one machine (divided into linear assembly line and non-linear assembly line, and the linear type refers to the assembly line in the assembly line. The layout of each part of the equipment is basically a DC type, rather than a straight line (it means that some of the equipment in the assembly line has a corner layout) and the required production capacity. It can be 2-4 groups. When the hot-pressing position 3 is a straight line, two sets can be set, so that the two sets of platform devices 5 need to be rotated 180 degrees to exchange positions; if the angle between the patch position 1 and the hot-pressing position 3 is 120 degrees, , 3 groups are required, at this time, if you need to rotate 120 degrees from hot pressing position 3 to patch position 1, you need to rotate 240 degrees (rotate in the same direction) from patch position 1 to hot pressing position 3, and set one in the middle Free position (other process operations can be developed in this free position, such as mounting other components, etc.).

The vacuum suction plate 542 is a flat plate made of metal with a thickness of 15mm-20mm. It is provided with several suction holes 541 communicating with the inner cavity 544 and having a diameter of 1.0mm-2.0mm. Two adjacent suction holes 541 The distance between them is 5mm-15mm.

On the part of the vacuum suction plate 542 that avoids the suction hole 541, there are several heating channels that can be inserted into the long rod-shaped heating rod 543. The suction hole 541 and the heating rod 543 are horizontal and perpendicular to the direction of the heating rod 543. Misplaced settings.

All heating channels are parallel to the short sides of the vacuum suction plate 542 and evenly spaced therebetween. The opening of each heating channel is located on the side of the long side of the vacuum suction plate 542. The heating channel can be a passage through the vacuum suction plate 542, or It can be a blind channel with a closed structure at one end, and the heating rod 543 placed in the heating channel heats the vacuum suction plate 542, and the heat is dissipated upwards from the top surface of the vacuum suction plate 542. This structure can make the heating rod 543 close to the top surface of the vacuum suction plate 542, so that the heat generated by the heating rod 543 can be evenly and concentratedly distributed on the surface of the vacuum suction plate 542, and can avoid the heat caused by the heating rod 543 and the suction hole. 541 intersect in space (that is, a part of the heating rod 543 passes through the suction hole 541), resulting in uneven heat distribution.

In order to radiate the heat energy generated by the heating rod 543 to the surface of the vacuum suction plate 542, a heat insulating layer 548 is provided on the bottom surface and the sides of the vacuum sealing plate 545, and at the same time, a heat-insulating layer 548 is provided on the side of the lead-out end of the heating rod 543. The wire cover plate 546 for insulation isolation and heat insulation function, when installed, the side of the cover wire plate 546 is adjacent to the rotating machine 211, and this setting will not affect the rotation of the rotating machine 211.

The vacuum sealing plate 545 is made of heat-resistant heat-insulating material, its thickness is 15mm-20mm, its center is a concave cavity, and a vent hole is provided on the short side of the vacuum sealing plate 545, and the vent hole passes through the The air pipe 547 is connected with the suction system of the peripheral equipment.

For the air extraction system of peripheral equipment, the present invention preferably adopts an air extraction pump with large suction force and high temperature resistance, and the reasons are as follows:

1) It can generate a sufficiently large negative pressure airflow, and by reasonably designing the ratio of the cross-sectional area of the suction port to the total area of all suction holes 541, a negative pressure sufficient to adsorb the flexible circuit board on the surface of the vacuum suction plate 542 can be obtained .

Since there are some positioning holes on the flexible circuit board (multiple positioning holes need to be set on it during the production process of the flexible circuit board), if the air extraction system adopts a mechanical vacuum pump to pump air, it will cause air leakage from the positioning holes. As a result, the air extraction effect is poor. Therefore, the present invention adopts air extraction equipment with large suction force and high temperature resistance, such as a blower.

2) It can work continuously. Since there are two platform devices 5, during the whole process, there is always a suction plate 54 on the platform device 5 that needs to absorb the flexible circuit board. Therefore, the air extraction system needs to be in operation all the time. State, the present invention is to be connected to the suction pipeline of two suction stick receiving plates 54 and electromagnetic valve switch is set. When the semi-finished flexible circuit board placed on a certain suction receiving plate 54 needs to be sent out after completing the thermal pressing operation, the air path connected to the suction receiving plate 54 is disconnected, so that the manipulator can easily place the finished flexible circuit board Grab and send. And the air path connected with another suction sticker receiving plate 54 remains in the connected state.

3) The equipment investment is small, and the blower with large suction force is used, which is cheap and easy to install.

The handle 127 is fixed on the installation base plate 121 for convenient disassembly and assembly of the positioning device 12 .

When the bearing platform device 5 rotated to the mounting position 1 is ready to enter the process operation of mounting the reinforcing steel sheet, the bearing platform device 5 moves forward a set distance (that is, the "set sticker" in the aforementioned "second" point) piece position"), the lower ends of the four guide posts 53 on the platform device 5 respectively fall into the plane space occupied by the push-up plate 124 in the vertical direction, at this time, start the fourth cylinder 125, and the upward moving The push-up plate 124 touches the guide post 53 to lift up the guide post 53 and lifts the suction-attach receiving plate 54 to a limited height, so that the placement machine 11 can accurately mount the reinforcing steel sheet on the raw material. The position set on the flexible circuit board.
