Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Industrial Application Field] This invention provides a method for cutting a ring material of a multilayer board such as a glass epoxy resin multilayer printed wiring board or a glass polyimide resin multilayer printed wiring board. The present invention relates to a board mounting table for a cutting machine that cuts into required dimensions.

[Conventional technology and its problems]

When resin multilayer printed wiring boards were manufactured, they were the first
As shown in FIGS. 7 and 18, the ring of material has an irregular outer shape, so the ring must be cut to give a constant product outer shape. Further, depending on the purpose of use, it may be necessary to further divide and cut into several pieces as shown in FIG. 19. Conventionally, when cutting such multilayer printed wiring boards, a toilet with diamonds electrodeposited around a metal disk has been used as a cutter.

During the cutting process, a multi-N substrate W for cutting is placed on a jig plate that is conveyed and moved on a conveyor or roller, etc.
Currently, the cutting process is carried out by carrying the machine to a cutting station, positioning it, clamping it, and fixing it. Furthermore, in a so-called pallet return method using a large number of jig plates, multilayer substrates for cutting with different cutting positions are placed on each jig plate, and the cutting process is performed using a large number of cutters. Conventional cutting machines of this type have a complicated mechanism, a large loss of mechanical equipment, and a large dedicated area within a factory. In addition, since the cutting and removal of the ring material and the cutting process to the required dimensions are performed using the pallet-so-tri-return method, the substrate to be processed must be clamped for each required dimension, complicating the work process.

[Purpose of the invention]

This invention was made in view of the above problems, and its purpose is not to mount a multilayer board for cutting on the jig plate of a cutting machine, but to cut a multi-N board in a preset manner. Position and mount it according to the dimensions and perform cutting, forward/reverse rotation, reciprocating movement, etc.

To provide a turning table which can be made into a compact cutting machine as a whole.

[Means to achieve the purpose]

In order to achieve the above object, the present invention provides a means for mounting a multilayer board in a multilayer board cutting machine, which includes a guide pin for board positioning, a cylinder for operating the guide pin, a pin for pushing up the multilayer board, and an air for operating the pushing pin. a rotation drive mechanism that includes a cylinder and rotates the upper part in forward and reverse directions;
Furthermore, the gist of the present invention is that it is a revolving table equipped with a revolving stop device.

[For production]

A multilayer substrate for cutting is mounted on the upper surface of the revolving table via a loading unit from a jig plate that is set at a predetermined position. Next, on the top surface of the turning table, holes in the multilayer cutting board that have been drilled in advance according to the required cutting dimensions are inserted.
The guide pin is inserted by the operation of the air cylinder. That is, an appropriate number of guide pins such as 4 or 8 guide pins are protruded and inserted into the holes in the cutting multilayer substrate manually or by using electromagnetic valves as necessary. As a result, the multilayer substrate for cutting is positioned and placed in an immovable state in the front, rear, left, and right directions. Next, the pivot drive mechanism is started at the bottom of the pivot table. That is, the actuator, which has a gear fitted to the two rotating shafts, is started, and the gear fitted to the rotating shaft of the actuator meshes with the gear fitted to the rotating shaft of the rotating table, thereby transmitting rotational torque to the rotating table. The turning table is 90
Once rotated, the stop device abuts and locks it in that state. When the necessary cutting process is completed on the top surface, the machine is rotated 90 degrees again to the original position, the glass material is removed, and the first cutting process is performed.This operation is repeated as many times as necessary. After the cutting process is completed, the push-up pin operates to remove the cut multilayer board from the upper surface of the rotating table.

〔Example〕

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an assembled plan view of a cutting machine for multilayer substrates according to the present invention, FIG. 2 is a front view, FIG. 3 is a left side view, and FIG. 4 is a right side view. As shown in these figures, the multilayer substrate W for cutting that has been transported from the jig plate 1 by the loading unit 2 is mounted on the turning table 11.

5 to 13 show details of this turning table 11. FIG. As shown in FIG. 5, the turning table 11 is made of a metal plate, for example, an aluminum plate, and the template 10 is placed on the top surface thereof. The reason why the template 10 is placed is because if the multilayer substrate W for processing is placed directly on the turning table 11, this turning table 11 will be damaged. A rotating shaft 13 is fixed at the center of the lower part as a turning drive mechanism for the turning table 11, and a gear 14 is fitted to the rotating shaft 13, which meshes with a gear 18 fitted to the rotating shaft 17 of a rotary actuator 16. It's a shame. This rotary actuator 16 is fixedly installed on the rotating table moving base 15. Further, a cross roller bearing 19 is fitted between a bearing holder 12 fixed to the lower part of the rotating table 11 and the rotating table moving base 15, and a guide 20 is fixed to the lower surface of the rotating table moving base 15, and a guide 20 is fixed to the rail 21. Inserted and mounted on the rack. In addition, as shown in FIGS. 6 and 7, a dock 22 is provided protruding from the bearing holder 12 fixed to the lower part of the rotating table 11, and a stopper 23, 24 with a shock absorber is provided on the rotating table moving base 15. are arranged and fixed at 90 degree angles. That is, the rotation table 11 is 9
When the dock 22 and the stopper 23 make a 0 degree turn, the dock 22 collides with the stopper 23, the impact is alleviated by the shock absorber, and the dock 22 and the stopper 23 are abutted and locked in that state. in this way.

The rotating table can be rotated back and forth by 90 degrees by the rotating drive mechanism and the stopping device, and the multi-N substrate W for processing can be cut at right angles on the upper surface of the rotating table 11. As shown in FIG. 14, the entire rotating table can be moved by a ball screw 28 fixed to the rotating table 11, a male screw rod 26 screwed thereto, and a motor 27.

As shown in FIG. 19, on the upper surface of the rotary table 11, guide pins are inserted into pre-drilled holes in the cutting multilayer substrate W in order to not only cut the glass material but also to cut it into predetermined dimensions. Alternatively, the pins can be operated to push up the cut multilayer substrate W from the template 10. First, the substrate W is cut into predetermined dimensions.
We will explain how to insert a guide pin when cutting.

FIG. 8 is a view of the aluminum plate of the turning table 11 viewed from the front side. 9 is a sectional view taken along arrows A to H in FIG. 8, and FIG. 10 is a sectional view taken along arrows I to N in FIG. 8. In these figures, Gl to G22 are guide pins for setting predetermined cutting dimensions, Tl-T4 are crank pins for fixing the template 10, and El to E12 are push-up pins for pushing up the processed base plate W. show. As mentioned above, holes are pre-drilled in the processed substrate W according to the cutting dimensions, and the guide pins C1-022 of the turning table 11 in FIG. 8 are drilled in accordance with the cutting dimensions as shown in FIG. It is inserted into the punched hole of the multilayer substrate W for cutting. This insertion is performed by operating the air cylinder 11a shown in FIG. The air cylinder lid in FIG. 10 shows an example of use in which the guide pin has a large hole diameter, but in this way, the guide pin diameter can be changed depending on the hole diameter of the cutting substrate.

Normally, when cutting the substrate W, the cutting substrate W is placed on the template 10, so the template 1
0 is also provided with the aforementioned guide pin hole. In addition, the template 10 is fixed to the aluminum plate 11 by operating the clamp pins T1 to T4, but the air cylinder ll
b is an air cylinder for operating a clamp pin that fixes the template. Both air cylinders are activated by manual operation. Use the cut multilayer substrate W as a template l
To remove it from O, use the air cylinder IIC, which activates the solenoid valve and causes the guide to protrude as shown by the imaginary line.

Next, a method of operating these air cylinders or solenoid valves will be explained. FIG. 11 is a view of the rotating table 11 from the back side, and each air cylinder lla, llb
, llc, and lid are arranged. Figure 13 is the 11th
It is a Q arrow view of a figure.

2 to 3 are switches for the guide pin actuating cylinder lla, and 2 is a switch for the template clamp pin actuating cylinder llb. When setting a predetermined cutting size 1 For example, when cutting only the glass material as shown in FIG. 19 (a), set the switch ``■'' in FIG. 11 to cut the guide pin Gl.

G2. G3. When the air cylinder lla for G4 is activated and you want to cut to dimensions like (c), press the switch ■
and ■, the guide pins 01 to G4 mentioned above and guide pin G5. G6. The air cylinders 11a for G7 and G8 are activated. In addition, when cutting a processing substrate W having different vertical and horizontal dimensions, for example, when cutting into dimensions as shown in FIG. GIO, Gl 1. G12
and guide pin G13. G14. Air cylinder lla for G15,016 is activated. As is clear from these descriptions and FIGS. 8 and 11, some guide pins are used for the same purpose. Alternatively, these guide pins may be inserted into holes previously drilled in the revolving table by an operator without using an air cylinder.

Also, if you turn on the switch ■ in Figure 11, template 1 will be displayed.
Air cylinder llb for clamp pin 0 is activated.

Further, as described above, after cutting, the air cylinder 11C is operated by the solenoid valve to remove the cut substrate W from the template.

Note that when removing the cut substrate W from the template 10, the guide pins are usually removed while being inserted into the substrate W, but there are cases where the substrate W cannot be removed from the guide pins. In such a case, the guide pins may be lowered to the lower surface of the template 10 first, and then the cut substrate W may be lifted up.

FIG. 12 is a sectional view taken along the line EJ in FIG. 11.

11e is an air passage for cylinder operation, 11r is a manifold for a solenoid valve, and 11g is a rail.

Next, a device for clamping and fixing the multilayer substrate W for processing on the surface of the turning table 11 will be described, although it does not constitute a part of the turning table of the present invention. 15 and 16 are a sectional view and a partial side view of a clamping and fixing device for a multilayer substrate W for processing.

31 is a clamp, and a rubber plate 32 having a rectangular cross section is attached to the side facing the rotating table 11. A hardened shaft 33 is suspended from both sides of the clamp 31 and is fitted into a bearing 34 fixed to the frame 9. Reference numeral 36 denotes a connecting rod, which is pivotally connected at both ends to a crank arm 37 fitted to the hardened shaft 33 and the countershaft 35. Also, counter shaft 35
A crank arm 38 is fitted near both ends of the crank arm.

It is rotatably connected to an operating shaft 39 of an air cylinder 40 fixed to the frame 9. When the turning table 11 carrying the processed substrate W is set at a predetermined cutting position and the air cylinder 40 is operated, the crank arm 38
rotates together with the countershaft 35, and at the same time, the crank arm 37 also rotates in the direction of rotation of the countershaft 35, and the rubber plate 32 attached to the clamp 31 clamps and fixes the processing substrate W.

The turning table configured as described above is fixed by the above-mentioned processing multilayer substrate W clamping device, and as shown in FIGS. It travels and cuts the ring material of the multilayer board W into required dimensions set in advance. The cut end pillars are removed by a scraping device 4 shown in FIGS. 1, 3, and 4.
When the unloading unit 3 is removed and returned to the original central position, the unloading unit 3 is moved to the top of the turning table by the operation of the air cylinder 3a, the fingers 3b are operated, and the processed multilayer substrate W is recovered.

Although the rotary table according to the present invention is as described above, it is needless to say that it is not limited to the embodiments, and various modifications can be made within the same range as the creation of technical ideas. For example, the guide pins for positioning the multilayer substrate W for processing can be inserted not only by an air cylinder but also by two workers manually. Further, the turning drive mechanism of the turning table 11 is not limited to gear drive, but it is also possible to use a sliding mechanism using a friction wheel, a belt wheel mechanism, or a cam mechanism.

A pin, an air cylinder for operating the push-up pin, and a drilled hole for the pin,
The lower part is equipped with a rotation drive mechanism and a stop device for rotating the rotation table in forward and reverse directions, so one rotation table can be used to cut a multilayer board in four directions or to divide it into several pieces. When cutting, division cutting into preset dimensions becomes possible. Additionally, since positioning can be performed using guide pins, processing accuracy is improved. Furthermore, since the structure of the machine can be made compact, the area dedicated to the machine in the factory can be reduced. In addition, the selection of guide pins, the movement, turning, cutting, and return of the rotary table are all easily controlled by computer, which improves work efficiency and requires fewer workers, making it an extremely excellent cutting machine for cutting multilayer boards. It is possible to provide a mechanism for
