(b) For the same reason, alignment takes time, is inefficient, and causes severe eye fatigue.

(c) For the same reason, even if you align with a magnifying lens,
Accuracy doesn't improve that much.

(d) In item (c), it is difficult to select the mounting position of the magnifying lens.

(e) It is difficult to perform ideal partial illumination near the drilling position.

(f) In principle, the chips are discharged in the opposite direction from the tip of the drill, so the chips accumulate on the upper surface of the workpiece during operation, impeding the alignment operation.

(g) The drill vertical mechanism is based on the lever principle, so
It generates a stronger thrust than necessary, which can break the small-diameter drill, making it difficult to control the amount of force applied.

(h) Wasteful strokes are likely to occur up and down the drill.

(j) The upper and lower handles of drills are arranged for right-handed use without exception, making it difficult for left-handed workers to use them.

(k) Heavy objects and precision mechanisms such as the motor, transmission, drill vertical mechanism, drill chuck, etc. must be placed in the space above the workbench and require great rigidity, resulting in large size and heavy weight, making it difficult to simplify. Missing.

Due to the structure developed by conventional drilling machines, The problems caused by this are listed above, Next, it is specific to printed wiring board drilling process. List the problems seen from the working conditions. The example is as follows.

(n) The required drilling density is always tens to hundreds of holes per sheet, which is not comparable to general drilling work. Therefore, the eye fatigue of the workers is severe.

(p) The hole diameter in (n) term is 0. 8mn ~1.0m
Limited to small diameters of m. The skill of the operator is required to prevent the drill from breaking or bending.

(q) Pretreatment work such as punching work is not possible due to the reason in item (n).

(r) In the case of mass production of a small variety of products, an NC drilling machine, profile drilling machine, or press processing is used, but in the case of small volume production of a large variety of products, for economic reasons, it is necessary to rely on drilling machine processing.

In summary, the conventional method of drilling holes in printed wiring boards using a drilling machine has many problems.

(d) Means for solving the problems In solving the above problems, the technical improvement goals for solving them are listed as follows.

(a) The operator's line of sight is aligned vertically upward on the extended line of the center of the drill rotation axis, and the operator is configured to be able to monitor this from directly above the drilling position.

In achieving the improvement goals of (d) (a) to (In), the basic principle of the present invention is to fix the drill and float the workbench.

That is, as stated in the above-mentioned section 3 (b), in the conventional technology, the workbench is fixed and the drill moves in a straight line against it, but in contrast to this, in the present invention, the drill is moved to the workbench. It is fixed to the lower pedestal and the workbench is moved.

Adopting this basic configuration results in numerous new functions and benefits.

All of the above-mentioned (d) terms (a) to (m) will be resolved.

Next, for convenience, the basic configuration of the present invention is designated as Example 1 and will be explained below using the drawings.

In FIGS. 1, 2, and 3, (1) the pedestal 1 includes a motor 6, a left sleeve 13, a right sleeve 11,
The upright part of the arm 3 and the spring 9 are fixed vertically.

(2) The drill chuck 7 is fixed to the rotating shaft of the motor 60, and the drill 8 is installed so that the drill chuck 7 can be replaced.

(3) Attach the left rod 1 to the workbench 2 having the drill hole 14.
2, the right rod 10 is vertically fixed so as not to cause any protrusions on the upper surface of the workbench 2.

(4) Insert the left rod 12 into the left sleeve 13 and the right rod 10 into the right sleeve 11. At this time, the parallel movement mechanism configured by each combination is adjusted so that it can slide smoothly with little rattling.

(5) Attach the transparent index plate 4 to the arm 3 with screws 15.

A cross-shaped index 5 is carved on the lower surface of the transparent index plate 4 at a position that matches the extension line of the center of the rotation axis of the drill 8.

(E) Function With the above structure, the upper surface of the workbench 2 is in weak contact with the lower surface of the transparent index plate 4 due to the biased spring 9.

At this time, if you lightly push down the left and right upper surfaces of the workbench 2 with the fingertips of both hands, the workbench 2 will move between the left rod 12 and the left sleeve 13.
, and by the action of the parallel movement mechanism formed by the combination of the right rod 10 and the right sleeve 11, it moves downward in parallel while always maintaining a plane parallel to the base 1.

As a result, the workbench 2 always moves linearly perpendicularly to the rotation axis of the drill 8 and relative to the drill 8.

Next, a specific usage example of the first embodiment will be explained using FIG. 4, FIG. 5, and FIG. 6.

(a) As shown in FIGS. 4 and 5, the workpiece 1
A printed wiring board 6 is inserted between the workbench 2 and the transparent index plate 4 against the spring 9 with the printed pattern side facing upward.

(b) Lightly hold the left and right sides of the upper surface of the workpiece 16, and while moving it horizontally, aim at the drilling position using the index 5 from directly above.

(C) Push the workpiece 16 downward against the spring 9 without changing its position.

At this time, the workbench 2 is pressed downward while being in close contact with the workpiece 16, and the surface of the workpiece 16 is maintained perpendicular to the rotational axis of the drill 8, and the position of the hole is not shifted. does not occur.

(d) The tip of the drill 8 relatively passes through the drill hole 14 and bites into the lower surface of the workpiece 16.

(e) When pressed down further, the state shown in FIG. 6 is reached, and the drilling process is completed.

(f) If you loosen the force, the repulsive force of the spring 9 will cause the drill 8 to
The removal is completed, and both the workbench 2 and the workpiece 16 return to their original states.

(F) Example Above, Example 1, which is the basic configuration of the present invention, has been explained, but since this configuration brings about various functional benefits, these benefits will be explained below. Various examples of new configurations that are used in combination will be individually explained as examples.

(1) Example 1 This has already been described in Section 3 (d) above.

(2) Example 2 In Figures 7 and 8, 1 pedestal 1 and vertical Immediately fix the lower end of the rod 17 and Attach stopper 18 to the end and screw 19. It is installed so that the vertical position can be adjusted. do. Next, move the arm 3 to No cut at the edge, arm par 21 and struts 20, with sleeves 22 interposed between them. and fasten it with screws 23. Mounted so that the height can be adjusted with 24 Ru. The lower end of the pillar 20 is perpendicular to the pedestal 1 Fix it.

With this configuration, the lifting and lowering limits of the workbench 2 are limited by the transparent index plate 4 and the stopper 18, thereby eliminating unnecessary drilling strokes and improving work efficiency.

(3) Embodiment 3 FIGS. 9, 10, 11, and 12 show a method of attaching a positioning magnifying lens. 9 and 10, one end of a transparent resin rod 26 is processed into the shape of a convex lens 25, and the other end is bonded to the upper surface of the transparent index plate 4. In FIGS. In FIGS. 11 and 12, the lens 25 is fitted into the frame 27, and the handle 28 is fixed to the arm 3 with a screw 29 via a bush 30.

By doing this, you can align the drilling position. This makes it extremely easy to compensate for poor eyesight. As well as increasing fatigue, it reduces fatigue. The effect is great. center of drill rotation axis, Workpiece drilling center, index center, lens lens center, lens focus, and operator align all lines of sight on the same line The configuration of the present invention that can be This was something that could not be achieved with the configuration of technology. be.

(4) Embodiment 4 FIGS. 13 and 14 show a configuration for obtaining ideal local illumination near the drilling position. A light bulb hole 31 is provided in the arm 3 on the surface where the arm 3 and the transparent index plate 4 come into contact, and a light bulb 32 is enclosed in the hole. When the joint surface is irradiated with the light bulb 32, the light is diffused by the transparent index plate 4, making the index 5 appear and locally illuminating the upper surface of the workpiece in the vicinity thereof. This is a method that cannot be achieved with the configuration of the prior art, and since the entire illumination device is confined to the tip of the arm 3, it does not interfere with the work at all, and unlike the conventional external illumination system. , no shadows, no harmful reflections, and no glare from the light source directly entering the mouth.

(5) Example 5 FIG. 15 shows the bottom surface of the drill hole 14. Obtain illumination by passing through semi-transparent workpieces This is an example of a method.

The material of the printed wiring board to be processed in the present invention is mainly glass epoxy or Bakelite, and the board thickness is about 1.5 m+, so it has a translucent property to light.

In this hole-drilling process, the printed pattern has already been etched, and when the printed wiring board is strongly illuminated from the back side, the copper foil part of the pattern stands out in black silhouette very clearly.

Utilizing this characteristic, in this configuration, the drill hole 14 through which the drill 8 passes is also used as a light introduction hole, and the workbench 2 is illuminated from below with a light bulb 32. In this way, the printed pattern clearly appears locally on the upper surface of the workpiece placed on the workbench 2, making it extremely easy to align the holes.

(6) Example 6 Example 6 utilizes the characteristics of the printed wiring board described in Example 5, and is designed to obtain illumination from the back side of the printed wiring board. This is intended to improve work efficiency by clarifying the relationship between hole positions and making it easier to confirm the position of the next hole in repeated drilling operations.

In FIGS. 16 and 17, a relatively large window is made in the workbench 2, and a transparent or transparent resin plate 35 with drilled holes 14 is inserted and fixed therein. If this resin plate 35 is not provided, small workpieces may fall out of the window, causing inconvenience. When the resin plate 35 is irradiated with the light bulb 32 from below the workbench 2, a wide-range naprint pattern of the part corresponding to the surface of the resin plate 35 (11) appears black and silhouette-like, making the drilling and positioning work highly efficient. can.

(7) Example 7 Figures 18 and 19 are blowing away chips. Show the device. According to the configuration of the present invention, In principle, chips are discharged below the workbench. be done. A drill is placed on the top surface of the workpiece. When 8 passes through the dirt, a small amount remains. However, it is necessary to remove the accumulated chips. The arm 3 and the transparent index plate 4 are The air introduction hole 36 is placed on the contact surface of the arm. 3, fix the connecting pipe 38, and Connect the air pipe 39 to this. On the other hand, Tooru The bright index plate 4 has 5 air introduction holes 36 and an appropriate Pass the air exhaust hole 37 through the let With this configuration, the air pipe The air injected from 39 is discharged. from the hole 37 to the lower surface of the transparent index plate 4. Spray onto the top surface of the workpiece you are touching. and chips are removed. Anaka During machining, the top surface of the workpiece is covered with a transparent index plate. Although it is a little different from 4, there are no problems in terms of effectiveness. The 9-wire configuration that does not occur in the prior art is This is an impossible method due to its structure.

Note that the water is ejected onto the lower surface of the transparent index plate 4. The air is concentrated near index 5, and further In order to increase the effect, the air exhaust hole 37 is It may be tilted, and it may be placed under the transparent index plate 4. Grooves are machined on the surface to serve as air flow paths, It may also be communicated with the air exhaust hole 37.

(8) Embodiment 8 Embodiment 8 is constructed by combining the advantages of Embodiments 4 and 7, and is a system that simultaneously provides ideal local illumination and removes chips. As shown in FIGS. 20 and 21, a light bulb hole 31 is formed in the arm 3 on the surface where the arm 3 and the transparent index plate contact, and the light bulb 32 and the socket 34 are hermetically sealed with a rubber stopper 40. An air introduction hole 36 is opened in a part of the light bulb hole 31, a connecting tube 38 is fixed, and an air tube 39 is attached to this.

The transparent index plate 4 has a hole corresponding to the light bulb hole 31. Open the air exhaust hole 37 at the position where Ru. In this way, the path of the ray and the air If the same flow path is taken, the area around index 5 Provides ideal local illumination and You can also blow away powder at the same time. Ru. In addition, as an incidental effect of this, Since the sphere 32 is cooled by the air flow, the Prevention of overheating of the tip of arm 3 and light bulb This has the advantage of increasing the lifespan.

With conventional technology, this configuration cannot be achieved. It's a good thing.

Embodiment 9 In Embodiment 9, as shown in FIG. 22, several layers 1i41 with an open top are attached to the upper surface of the motor 6 to prevent chips from scattering. Since, in principle, the chip discharge direction of the drill 8 is opposite to its tip, several layers are possible with the configuration of the invention. Furthermore, since the drilling machine of this construction is essentially small and lightweight, several layers of chips can be thrown away to the outside by overturning the single body itself.

In the configuration of the prior art, the tip of the drill 8 Due to the downward facing part, it is structurally It was impossible.

(10) Example 1゜ Example 10 is shown in FIGS. 23 and 24. All mechanical rotating parts as shown, Electrically charged parts and parallel motion machines the structure so that it does not interfere with the movement of workbench 2. At a high height, surround the entire circumference with a shroud plate 42. This was designed to prevent danger.

According to the configuration of the present invention, the drill 8 is mounted on a stand. Indirectly fixed to seat 1 and spatially immobile , and arm 3 is similarly immovable. , the distance between the drill 8 and the transparent index plate 4 The separation is constant regardless of the movement of workbench 2. Unchanging. Therefore, the tip of drill 8 penetrates the transparent index plate 4 and is exposed to the outside. I will never release it.

In addition, mechanical and electrical elements are All are stored on the top surface of the seat 1.

With these configurations, mechanical rotating parts Exposing electrically charged parts to outside space The structure of this case that does not It is something that In conventional technology, drill 8 Expose the tip of the on the top of the workbench 2. is an absolute structural and operational requirement. Therefore, it is possible to obtain a structure like the one in this case. was impossible.

Note that by using the shroud 42, In addition to giving a beautiful appearance, it also switch 43 and power cord 44. Can facilitate installation.

Example 11 Figure 25, Figure 26, Figure 27, and Example 11 shown in FIG. The horizontal X-axis direction and the horizontal Y-axis direction are displayed on the index plate 4. By adding a micro-adjustment device in the direction, the drilling position can be adjusted. This is intended to improve accuracy.

In the figure, a bolt 51, a spring 54. Natsu 47. The slider 55 is attached to the arm 3 using a washer 56. The slider 55 can be slightly moved in the horizontal Y-axis direction relative to the arm 3 by a bolt 49, a spring 53, and a Y-axis adjustment screw 46. On the other hand, the transparent indicator plate 4 is loosely supported at one point by the slider 55 by a countersunk screw 5o, and can rotate around this point. The transparent index plate 4 is connected to the slider 55 with a bolt 48, a spring 52, and an X-axis adjusting screw 45, and can be slightly moved in the horizontal X-axis direction.

Constructed as above, first, index 5 is Approximately aligns with the center of the hole drilling position on the workpiece. and drill a hole. Next, processed The center of the hole and the center of index 5 are the X axis and Y axis. Accurate alignment using a fine adjustment device on the shaft.

By doing this, the next drilling process In drilling, simply aim at the drilling position using index 5. You can obtain perfect hole positioning accuracy just by Ru. This configuration cannot be obtained with conventional technology. It is a method.

Example 12 Figure 29 shows the vertical movement of workbench 1 and 2. Example with added Rickstop function 12 shows the configuration of No. 12.

The invention described in Section (1) above and Example 1 Akira's basic concept is the vertical position of workbench 2. According to the drilling positioning process, The drilling process is independent of each other. This is because it is performed in continuous motion. Ta.

It is different if you are a skilled person, but it is not possible if you are an unskilled person. During the alignment process, the workpiece The pressure is too strong, and the workbench 2 is pressed down a little. As a result of lowering it, the tip of drill 8 May damage the bottom surface of the workpiece.

In order to eliminate such problems, this book In the configuration, as shown in Figure 29, the right side Circulate this around a part of the rod 10 The circumferential groove 66 is machined, and the fabric side slit is A screw 71 is machined on the tip of the tab 11 to increase the height. Attach the height adjustment screw 70. height adjustment Attach the leaf spring 67 to the screw 69 to the screw 70. and attach the ball 68 to this tip. Inset, circumferential groove 66 and leaf spring 67 Contact with the power of animals. Like this Then, workbench 2 can be clicked at any height. It is expected that a stop effect will be applied. , drilling positioning process and drilling process The process can be clearly separated, making it extremely easy to use in actual work. It is valid.

(13) Example 13 In the basic configuration of the present invention, there is no problem if the number of printed wiring boards to be processed is about 1 to 3, but if the number of printed wiring boards to be processed simultaneously increases, or as a special case, thin metal In this case, even if the left and right upper surfaces of the workpiece are held down with the fingertips of the hand, the cutting pressure of the trill tends to cause the workpiece to float away from the workbench, causing problems. The reason for this is that horizontal holding of the workpiece relies on two-point support at both the left and right fingertips. Generally, the condition for maintaining the horizontal stability of an object is to support it at a minimum of three points. Therefore, if one more fulcrum is provided in addition to the kunate fingertip, the above problem should be resolved, but in Example 3, for convenience, we will explain a method using four-point support. .

Figures 30, 31, and 32 , place the right pusher on the right side of the top of the workbench. Connect the arm 58 to the right separator 62. Attach with screws 64.

Similarly, the left push arm 59 is fixed to the left side of the workbench 2 with a screw 65 via a left separator 63. Right presser arm 58. Each left presser arm 59 has a right pin 60. Attach the left pin 61. The tips of the left and right pins 61 and 60 that hold the upper workpiece are placed with a slight gap between them and the upper surface of the workpiece that is in contact with the lower surface of the transparent index plate 4 on the workbench 2''. Adjust so that there is no problem with the horizontal movement of the workpiece.

With the above configuration, the third term, (e), and (a)
) - (f) When drilling using the working method described in sections, even if you hold down the workpiece by the left and right fingers and push the workbench 2 downward, the top surface of the workpiece will resist the thrust of the drill and move from side to side. It was also held down by pins 61.60, resulting in a total of four points of support, making it possible to drill holes with a considerable amount of force, and the workpiece did not separate from the workbench 2, resulting in an extremely stable effect.

Example 14 Figures 33 and 34 show small diameter drills. No. 8 is broken, bent, shaken, or loose. To prevent the tip of the drill 8 However, it will be short and prominent to the minimum necessary. Uni, sure with bearing 72.73 The structure of Example 14, which was directly held, is shown. vinegar. On pedestal 1, left and right standoffs 7 6. Fix the 75 vertically and place the bearing A retaining plate fitted with an outer ring 72 of 74 with screws 78 and 77, and the bearing The inner ring 73 of is the center of the axis of the drill 8. Left and right standoffs to match Installed on 76.75.

With the above configuration, the rotation of the tip of the drill 8 No rolling was felt at all, and the work Drill the workpiece by rapidly lowering the table Even if it collides with the tip of 8, it will not bend or break. No loss occurred.

Such a configuration is possible because the drill 8 is fixed in space, and there is no problem in operation even if the drill 8 and the inner ring 73 are fixed with an adhesive.

On the other hand, in the conventional technology, the drill 8 The operation is to move in the direction of the rotation axis. Since the above is an absolute requirement, if this If you try to apply it to The end protrusion dimension cannot be kept constant, and in principle impracticable.
