Description of the Invention: [Technical Field of the Invention] The present invention relates to a hole processing machine for a printed circuit board. [Prior Art] The hole forming machine for a printed circuit board is composed of, for example, a combination of three types of boring operation, Y/X axis operation, and Z axis operation as shown in Fig. 8 (in addition, the z-axis operation is assumed to be imaginary As shown by the line, it repeats with the part of the χ or γ axis.) In general, the action of the X-axis or the γ-axis refers to the positioning of the plane, and on the other hand, the action of the Ζ-axis refers to the vertical movement of the yaw. Further, the action (cut) for the cutting operation is performed. The action of the cutting is to pull the drilled bit from the printed substrate (rise). In these actions, the + 动作 action can be said to be a meaningless action. Because of this +ζ action, it is not the action of =================================================================================================== The table raises the Z axis with a higher acceleration. 'When the Z axis is raised, there will be a fine drill bit that is easy to have two accelerations. - The vibration of the +Z action will shake the whole machine. The relative positional offset is generated. The other 4 makes the drill bit and the printed descending body as a whole higher acceleration: the reason is that the drill bit is pulled out vertically when the lifting method is used. The degree s Wu difference 'causes no 6) 01 In terms of point, it is extremely important to configure the fine drill « .. θ ^ main phase to break the motor, the descending body, the drive shaft and the mandrel. Therefore, in Patent Document i, it is strong.

The drive motor of the second battle port 6 is independent of the drive motor of the movable branch group 3. The 8 series is connected to the ball screw of the output shaft of the drive motor. The ball is formed, for example, from the upper end portion to the lower end portion with a right-handed thread. The 9-series has a lifting body that is engaged with a guiding mechanism (a linear guide which is disposed on the inner wall surface of the two bodies 3 in a vertical state), and the lifting body 9 is formed into a box having a stepped shape. shape. The elevating body 9 is composed of a longitudinally-shaped cylindrical screw-like portion 9a that is screwed to the ball screw 8 at the rear side, and a vertically long cylindrical holding portion 9b that is connected to the front surface of the screwing portion, and the holding portion 9b is attached. The heart sleeve 12 is attached with a spindle 13 or a drill bit 14 for opening a hole in the printed substrate 7. The elevating body 9' can be moved freely in the direction of the upper and lower shafts by the driving force of the drive motor 5 and the ball screw 8. Further, the opening machine having the above configuration is provided with a mechanism for absorbing the vibration of the spindle, and the vibration of the spindle is maintained by the inertial force of the lifting body 9 1352561 (spindle holding body) 9. And produced. The vibration absorbing mechanism 15 is referred to as a "vibration damper (damper)", and is provided in a plurality of up and down directions between the mandrel lifting body (housing) 9 and the lower end of the movable saddle 3 Spring member. The vibration reduction device (damper) is required to include a spring 2 plate, an i-th member fitted to the spring support plate, and a second member fitted to the lower end plate 3 of the lower portion of the movable type 2, and the like. The member has a configuration, and Patent Document 2 does not describe or suggest that the vibration is attenuated to prevent the drill from being damaged. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2004-263825 [Patent Document 2] JP-A-2002 No. 4948 [Summary of the Invention] The main purpose of the birth is to prevent the production of the lifting body by the lifting movement. hurt. Specifically, the motor is driven in a well-balanced manner, the drive screw, and the lifter having the mandrel on the front side, so that the weight of the lift is substantially the same as the axis of the member (vertical drive screw) that drives it. The full length of the screw is positioned in the heart = the weight of the weight member (weight) can be easily attached to the drive, and the weight of the lifter can be reduced. The fourth purpose is to prevent the fall of the lifting body when the power is turned off. b—Small words, as a mechanism f to prevent the lifting body from falling naturally due to gravity during power failure, it is better to install the damper (including the spring) as described in the literature 2 Composition of components, etc., etc. The fifth object is to positively support the side of the connecting portion (the upper end portion of the driving shaft) of the output shaft of the driving motor and the upper end portion of the driving screw. The hole punching machine for a printed circuit board according to the present invention includes: a movable branch body that is movably movable in a front-rear direction in front of the fixed body; and the elevating body is provided to be movable through the movable support by a driving force of the driving motor The vertical rail of the body is moved from the vertical direction, and the driving motor is disposed on the upper portion of the movable supporting body and has a driving screw in a vertical direction; and the stage is disposed below the lifting body and movable in the front-rear direction. The utility model is characterized in that: a thread in one direction is formed on the upper side of the driving screw, and on the other hand, a thread in the other direction is formed on the lower side of the driving screw, and at least the vibration generated by the lifting action of the lifting body can be attenuated. The weight member is screwed into the thread in one direction, and the entire length of the driving screw is located substantially directly above the mandrel of the lifting body. Here, substantially directly above, the problem that the mandrel is attached to the elevating body due to the attachment of the mandrel to the axis of the drive screw which is relatively perpendicular to the vertical axis (e.g., lcm) is shifted forward and backward or left and right. (1) The problem of Patent Document 2 can be solved by applying the basic principle of the patent document to a hole drilling machine for a printed circuit board. That is, according to the present invention, it is possible to provide a punching machine for a printing substrate which can attenuate vibration generated by the lifting operation of the lifting body. As a result, it is possible to at least attenuate the vibration generated by the lifting operation of the juice drop body in the hole drilling machine, and prevent the damage of the drill bit. () In particular, as indicated in the column of the prior art, since the entire length of the drive screw 1352561 is located substantially directly above the mandrel of the elevating body, the angular error when the drill bit is pulled out can be minimized. As a result, damage to the drill bit can be prevented. Further, since the full length of the vertical drive screw is located substantially directly above the mandrel mounted on the elevating body, the vertical drive screw can be easily provided. P) As a mechanism for preventing the lifting body from falling due to gravity during a power failure, for example, a brake that prevents the lifting body from falling in the driving motor may be used.

(2) Next, 8A is a drive screw (ball screw) that is coupled to the output shaft 5a of the drive motor through the link mechanism 24, The drive screw forms a thread (left thread) 8a in one direction on the upper side, and another thread (right thread) on the lower side of the drive screw 8A on the other hand. (3) Next, at least The weight member 31 capable of attenuating the vibration generated by the lifting operation of the lifting body 9a is screwed to one of the driving screws 8a. The thread 8a in one direction is equivalent in Figs. 2, 3, and * Thread on the upper side. * Again The entire length of the driving screw 8A is located above (substantially directly above) the shaft 12A attached to the elevating body 9A. This is to allow the driving screw 8A to be easily disposed at the position of the center of gravity of the driving elevating body 9A. The member 31 and the elevating body 9A are arranged in an in-line state in the vertical direction. This is considered to have the balance of the driving screw 8a "the driving motor 升降 the lifting body 9A including the mandrel 12A" to achieve the main object of the present invention (to prevent damage to the fine drill bit) Further, the weight member 31, the screw 8a; the square tube and the cylindrical outer casing are fitted to the screw barrel 32. The screw barrel 32 includes a screw barrel 32 and is directly screwed to the front cylindrical body. 33 is a fixed portion and has an engaging portion 34 that engages with the upper side of the vertical guide 14 1352561 rail 1A of the movable support 3A. The weight member 3 is designed to counteract the reaction force as much as possible, and: (Quality " roughly. In addition, the screw barrel 32 and the weight structure, the piece: A: the balance of assembly, the individual components are integrated Constitut. - The test lifter 9A' and the drive screw 8 pattern 8b 蟫人.s + manpower universal screw. The other direction of the screw, the pattern 8b, the thread on the side of Figure 2 = 7. Lifting body -, As shown in Fig. 3 and Fig. 4, the right-aligning portion 93 has a pair of right and left engaging portions UA that are respectively engaged with the left M 9b 〇A of the movable body 3A; and a heart 卩. The left side is connected to the right side of the screw unit, and the "dry" is separated from each other. Therefore, the setting between the lifting body %曰 and the mandrel holding portion 9b is set. There is a predetermined opening & the weight of the elevating body 9A is reduced by the two parts. The mandrel holding portion 9b is formed so that the upper and lower ends are opened, and the mandrel holding portion 9b is also the same as the screwing portion 9a. I.

A, 11A (5) Next, as shown in Fig. 3, the drive motor 5A is fed: the joint portion side of the screw 8A is cut by a bearing mechanism, and the two structures are combined at the upper end of the movable branch body 3A. The end fitting cylinder 37 and the center selected by the fitting cylinder 37 are configured to have a wide mouth (6). Finally, the movable supporting body 3A is a frame structure having a vertically long frame shape. 2, a predetermined interval is formed in the vicinity of the sigma σ of the plurality of longitudinal members i, the screwing portion h 15 of the lifting body 9a is called 561, and the mandrel holding portion 9b of the lifting body 9A is engaged. Openings 40 are formed in the vicinity of each other. In the above configuration, since a thread of one direction (left thread) is formed on the upper side of the drive screw 8A, and a thread of another direction (right thread) is formed on the lower side of the drive screw, the arrow of Fig. 7 is used. It is shown that when the drive motor 5A is started and stopped, the lifter body 9A and the weight member 31 approach or separate from each other. The vibration of the lifting body 9A generated at the time of starting and stopping is canceled by the reaction forces in the opposite directions. Therefore, the vibration of the ascending body 9A is not transmitted to the side of the body 1A including the movable support 3A. This point has the same effect as the patent document (vibration attenuation effect). In terms of the relationship with the gravity of the constituent members, the weight member 3 1 and the juice descending body 9A are close to or away from each other as shown in FIG. Therefore, at the moment of power failure, the gravity of the weighting member 31 and the lifting body 9A is not suddenly applied to the driving motor 5A. Therefore, it is possible to prevent the failure of the driving motor 5A, the falling of the lifting body 9A, etc. - the weight member 31, The quality of the lifting body is considered to be set in a good balance. Moreover, whether or not the built-in brake is provided in the driving motor can be arbitrary, but is not a specific matter of the present invention. The present invention is applied to a printed circuit board manufacturer or an electrical component.
