Description

Clean apparatus for press "

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a press-mold cleaning apparatus for cleaning foreign objects in a press-mold.

2. Description of the Related Art Generally, a printed circuit board (PCB: Printed Circuit Board or PWB: Printed Wire Board) is used for electrically connecting various kinds of parts. Depending on the number of wiring circuit surfaces, a single-sided circuit board, , And classified into a rigid circuit board, a flexible circuit board, and a rigid flexible circuit board according to the bending characteristics of the board. Among them, the flexible circuit board and the light-and-flexible circuit board are widely applied to small-sized electronic products which have been rapidly developed in the field of electronic industrial technology. Since they are flexible, they are small in size, It is useful for products with Such a flexible circuit board is a laminated structure in which various materials are superimposed. The manufacturing process is a cutting process for cutting the copper-clad laminate, which is an original plate, according to a standard, a drilling process for forming a guide hole in the cut original plate, An etching process for forming a circuit by corroding the copper foil, a coverlay film pressing process for pressing the coverlay film at a high temperature after attaching a coverlay film to the copper foil, and the like. The coverlay film is attached to the surface of the substrate for insulation and circuit protection. The coverlay film is processed so as to expose the circuit portion by a punching operation before being attached to the substrate, and then attached to the disk. A so-called sheet method, and a roll-to-roll method. In the sheet method, a single coverlay film cut to an appropriate size is placed on a mold and punched, so that the user has to transport the coverlay film by hand, resulting in a very low work efficiency and a high defect rate of the product. In addition, the roll-to-roll method is devised to solve the problem of the sheet method, and the punching operation is automatically performed while continuously supplying the coverlay film by using the reel wound with the coverlay film.

In the case of a press, the moment of tapping is the most important functionally. Particularly, in the case of a film tap, when the tapping speed is slow, a burr occurs and the quality of the product deteriorates.

In addition, according to the prior art, particles, which are particles of a material generated in the pressing process, are generated and contaminate the mold. Contamination of such a mold interferes with the accurate press process, thereby deteriorating the quality of the product.

7, the rotation driving motor is rotated, and the brush roll 50 is also rotated to clean the surface of the mold. At the same time, the vibration cleaner is operated, and the foreign matter cleaned by the brush roll 50 is discharged through the vacuum pipe 46. In addition, the forward and backward driving motors 42 are continuously driven, and the brush support frame 40 advances and retreats to perform cleaning.

After the cleaning for a predetermined period of time, the driving motors (21, 42) return to their original positions. In this way, it is driven for a certain period every time cleaning is needed.

When cleaning is performed for a long period of time, the brush is worn to replace the brush roll 50. 8 to 10, the replacement of the brush roll 50 will be described.

Referring to FIG. 8, the brush roll 50 is fully engaged with the brush support frame 40. The central protrusion 61a is inserted into the center groove 51a and the insertion members 63a and 63b are inserted into the corresponding insertion grooves 61b and 61c to fix the brush roll 50 . And the elastic rotation shaft 61 is pushed by the elastic force of the spring 62. In this state, the brush roll 50 rotates and the cleaning process proceeds.

Referring to FIG. 9, the brush roll 50 is detachable. The brush roll 50 is pushed all the way to the left in the drawing. At this time, the spring 62 is in a state of being compressed by the elastic rotation shaft 61 and the insertion members 63a and 63b are separated from the insertion grooves 61b and 61c.

Referring to FIG. 10, the brush roll 50 is separated from the brush support frame 40. At this time, the end of the center protrusion 61a is curved or spherical so that the brush roll 50 can be pulled out as shown in FIG.

The assembly of the new brush roll 50 can be reversed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
