Description

Device for hole poocessing for PVC substrate

The present invention relates to a hole processing device of the PCB substrate, the pressing holes are installed on both sides of the upper part of the hole processing equipment, the drill is installed on both sides of the bottom of the pedestal so that the two holes at the same time to process or alternately process The purpose is to.

In general, the PCB substrate is mainly manufactured by processing holes for molding the substrate and then pressing and molding the substrate in a fixed state using the holes.

Conventionally, the method of processing a hole has been used as a simple operation of machining a hole by fastening a drill bit in a hole processing machine and then rotating the drill bit.

However, the conventional method has been to use a drill bit to drill the hollow hole when machining the hole to blow the air so that the chip and dust generated by the drill bit when the machining operation and the end of the machining work is separated from the machining surface Since the cleaning method has been used, there is a big problem that dust is generated.

In other words, the drill bit is blown out of the dust generated while processing the hole in the substrate by air to remove the dust to the outside to contaminate the air, which causes workers to cause diseases in the bronchus and respiratory system, so that workers work There was a problem that was avoided.

In addition, the conventional method is the main cause of the deformation of the material by the processing heat generated when the hole is processed to a thickness of 10㎜ in the hole processing material, the spindle rotates about 25 times when processing one hole, It has been processing precise and clean holes as a way to cool the heat generated while processing the hole while at the same time by ejecting the air toward the chip and dust generated by processing the hole little by little by going backward.

However, the above method has a disadvantage of severe pollution of air due to chips and dust, and also causes heat generation so that the material is deformed, which is a major cause of material defects. It was difficult to process accurate holes due to bending, which caused a problem of lowering production efficiency.

The present invention is designed to solve the above problems, by installing the spindle for processing the hole of the hole processing machine on both sides so that one side can replace the product while processing the hole, the time interval By reducing the productivity can be improved to the maximum, and also to enable the spindle to be operated by the servo motor to maximize the accuracy, the present invention will be described in detail by the accompanying drawings as follows.

In the upper part of the main body is provided with a pressing hole to move up, down, left and right, and at the lower end of the pedestal to install a spindle to which the drill bit is fastened so as to operate left, right, up and down, the main body (1) Tables (2) and (3) which are installed on the upper side of the table and operated before and after are installed left and right, respectively, and are operated by the servo motor (4) above and above the tables (2) and (3) of the main body. Install the pressing holes (5) and 6, but the lower ends of the pressing holes (5) and (6) and the table (2) (3) on the vertical line to install the spindle (7) to the left and right to operate each, respectively In the center of the sphere (5) (6) is provided with a nozzle (10) formed with a through hole (9) to blow out the air through the through hole (9) to discharge dust and chips, the outside of each spindle (7) In the center of the drill bit 13 is installed a support tube 12 is installed with a dust suction device 11 for sucking dust such as chips and dust There is a hayeoseo such that air is injected to form a through hole.

Referring to the operation of the present invention made as described above are as follows.

After setting up the position where holes are processed in the raw materials in the computer installed in the hole processing machine main body 1, the table 2 installed on the upper side of the main body 1 is pulled out to the front, and then the table 2 Lay out the product for hole processing.

When the table 2 is returned to its original state in the above state, the pressing hole 5 provided on the upper side of the table 2 moves to the site where holes are processed from the raw material and moves left and right, and then the servomotor 4 The raw material is lowered by) to compress the raw materials, and at the same time, the spindle 7 installed on one side of the lower end of the table 2 flows from side to side like the crimping hole 5 to move to the site where the holes are processed. As the bit rotates, it is raised by the cylinder to process the hole.

On the other hand, when such operation is performed on one side, the table 3 on the other side is taken out, the raw materials are stacked, and the above operation is performed again. At this time, the time when the hole processing equipment is operated on one side and the time when the hole processing equipment on the other side is operated, the worker works with a time difference so that the hole processing equipment on one side can be withdrawn after replacing the raw material.

As described above, the spindle 7 rotates to process holes in the substrate, and at the same time, by injecting air into the hollow shaft of the drill bit, dust and chips generated by the hole processing are sucked and discharged.

In other words, the hole is processed at the bottom of the product by the drill bit fastened to the spindle 7 so that each spindle 7 rotates upward. At the same time, frictional heat is generated by injecting air through a hole formed in the center of the drill bit. It can cool off and remove dust and chips.

When the hole is penetrated by the drill bits installed in the respective spindles 7, as described above, air is injected by the nozzle 10 installed at the center of the crimping hole 5, and dust and chips are injected upward by the drill bits. Spray again to send to the support cylinder 12, the dust suction device 11 is installed on the outside of each spindle (7) to be discharged.

That is, when the hole is processed by the drill bit and penetrates the product, the dust generated by the drill bit is sprayed upward by the force of the air injected from the drill bit, and the dust and chips are pressed into the respective pressing holes 3 and 4. By sending it back to the dust container to the air sprayed by the nozzle 10 installed in the) will prevent dust from accumulating or flying on the product.

As described above, the present invention can improve productivity by reducing the time interval by installing the spindle for processing holes of the hole processing machine on both sides so that one can replace the product while the other is processing the hole. In addition, the spindle is operated by the servo motor to maximize the accuracy. The structure and method are simple and easy to manufacture. It is a useful design that can improve the competitiveness by maximizing the precision by preventing dust or chips from accumulating on the product by air is injected from the drill bit and the pressing hole.

Although the present invention has been described with reference to the preferred embodiments, those skilled in the art can variously modify the present invention without departing from the spirit and scope of the present invention described in the utility model registration claims below. Can be changed.
