Description

The present invention relates to a holding and conveying mechanism of a film sticking apparatus, and more particularly to a holding mechanism used in a film sticking apparatus for a printed circuit board.

In general, it is necessary to attach a film for protection to one or both sides of a printed circuit board (PCB). This film is stuck by a film sticking apparatus. In the prior art, when the printed circuit board is transported to the film sticking table and the suction cup by the transport device, the upper and lower rollers on both sides are used as a clamping tool, and the printed circuit board is supported and transported by the frictional force between the upper and lower rollers. The film is attached to the surface of the printed board and the printed board is conveyed.

However, in a system in which the printed board is sandwiched by rollers arranged above and below both sides of the film sticking apparatus, the film cannot be stuck on the entire surface of the copper printed board. For this reason, after a film is affixed on a printed circuit board, the part where the films on both sides are not affixed must be cut off as an invalid area. This causes unnecessary waste. In addition, in a situation where the supply and demand balance of copper materials has collapsed and prices have risen in countries around the world, waste of copper materials increases costs to manufacturers. In addition, when using a roller as a clamping tool, even if the problem that the film cannot be attached to both sides of the printed circuit board can be solved, the roller transports the printed circuit board due to frictional force, so that it is applied in the transport process. Scratches on the film surface. Similarly, the problem of having to cut both sides of the printed circuit board must be faced. The most important point here is that printed circuit boards will be further lightened in the future, so when the technology of thin printed circuit boards such as paper matures and they are adopted, conventional rollers will be used. In the transporting means, there is a risk that the thin plate member may fall from the gap between the rollers in the process of being transported by the rollers. In addition, it is difficult to effectively control the tension of the plate, and there is a risk of causing poor pressure bonding of the film. Furthermore, when the printed circuit board is sandwiched and conveyed by the rollers on both sides, the film cannot be suitably attached, and the probability that bubbles or wrinkles are generated between the printed circuit board and the film becomes very high. Thereby, since the yield of the printed circuit board cannot be improved, there is a need for improvement.

DESCRIPTION OF EMBODIMENTS Embodiments showing the objects, features, and effects of the present invention will be described in detail with reference to the drawings.

For simplicity of explanation, only the structure showing the technical features of the present invention will be described. FIGS. 1-3 is sectional drawing which shows the main improvements of the clamping conveyance mechanism of the film sticking apparatus of this invention. 1 to 3 show a film sticking device used for sticking a film to the surface of a printed circuit board. A film transport device 2 in which a plurality of rotating shafts are arranged on the upper and lower ends of the film sticking device 1. Is placed. Further, a displaceable film sticking table 3 is disposed opposite to an end portion adjacent to the film transporting device 2 and adjacent to the platform of the film sticking device main body 1. Moreover, the cutter base 4 used for cutting a film and the flattened suction cup 5 are disposed at appropriate positions. By the film sticking apparatus 1 having the above structure, a film pressure bonding process for sticking a protective film to the surface of the plate A (printed substrate) is performed.

  In addition, a transport device 6 composed of a plurality of rollers is disposed horizontally at the front end of the opening of the film sticking table 3. The conveyance device 6 conveys the plate body A arranged on the platform in the direction of the film sticking table 3 with a roller. The film sticking apparatus main body 1 is provided with a middle transport mechanism 7 extended from the transport device 6. As a result, the plate A is transported from the transport device 6 to the intermediate transport mechanism 7. The intermediate transport mechanism 7 in the present embodiment is configured by arranging ratchets between some vertical transport devices.

  The main improvement in the present invention is that the clamping mechanism 8 is slidably disposed in the center of the end of the film sticking device 1 opposite to the transport device 6 of the film sticking table 3. The clamping mechanism 8 can be moved back and forth in the horizontal direction when the power of the belt is transmitted. The structure of the clamping mechanism 8 is shown in FIGS. 4 and 4A. As shown in FIGS. 4 and 4A, the clamping mechanism 8 includes a fixed base 81 having belts bonded to both sides, an upper holding body 82 fixed to the fixed base 81, and a front end that can be opened and closed vertically and a lower holding mechanism.

  The overall operation method of the film sticking device main body 1 of the present invention is as follows. First, the plate A is transported to the film sticking table 3 by the transport device 6, and a protective film is pasted. Since the flattened suction cup 5 is in an open state when the plate A passes through the film sticking table 3, the holding mechanism 8 can easily hold the front edge of the plate A to which the film is attached. it can. Next, the clamping mechanism 8 is horizontally shifted rearward by the belt, and at the same time, the flattened suction cup 5 is closed, and the gap between the plates is reduced (that is, the film is attached). Approaching the upper and lower surfaces of the obtained plate A). As a result, the film can be adhered flatly without wrinkles on the plate A, and air can be prevented from entering and generating bubbles. When the clamping mechanism 8 is moved horizontally to a predetermined rear position, the plate A is opened and left on the inclined stage of the intermediate conveyance mechanism 7. Next, when the middle stage transport mechanism 7 is moved up and down, the inclined stage becomes horizontal, and the plate A is transported from the middle stage transport mechanism 7 to the rear rear stage transport mechanism (not shown), and subsequent processing steps. Is done.

  The present invention can achieve the effect that it is not necessary to cut the plate body A with the film attached to the surface by the structure described above, and the plate body by the design of the film sticking table 3 and the flattened suction cup 5. The space between A and the film can be flattened to reduce the generation of bubbles. Further, the upper clamping plate 821 and the lower clamping plate 821a of the clamping mechanism 8 are detachably fixed to the upper clamping body 82 and the lower clamping body 82a, so that the inner edges of the upper clamping plate 821 and the lower clamping plate 821a are soft. When the cushion 83 is damaged by prolonged use, the upper clamping plate 821 and the lower clamping plate 821a can be removed and replaced with a new soft cushion body 83, so that the operation can be continued.
