Abstract

PURPOSE:To enable the effective washing and burr-eliminating of a work large in its width, without increasing the discharge amount of a pump and by using a small number of jet nozzles, by moving the work in the intersecting direction of the nozzle reciprocating direction, with respect to a super high pressure jet nozzle in the state of rotating and reciprocating motion. CONSTITUTION:Unfinished works are mounted on a conveyer 54 and transferred in the arrow direction by starting a motor 58; a transfer stand 14 is subjected to reciprocating motion in the right and left direction by a motor 24; in accordance with this reciprocating motion, a motor 50 also is driven and a nozzle 40 is rotated; in this state, a discharge pump is driven and a super high pressure water jet flow is gushed against a work 56 from the nozzle 40. As a result, the super high pressure water jet flow gushed from the nozzle 40 jet-scans the work 56 while drawing a locus of zigzag and spiral types. Thus the washing and burr-eliminating of a work 56 is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a workpiece cleaning/deburring device that cleans and deburrs a workpiece using an ultra-high pressure jet stream.

(Background of the Invention) Ultra-high-pressure jets of water, cleaning fluid, or the like are sometimes applied to clean workpieces such as frames of IC boards or to remove debris from the workpieces. In this case, since there is a limit to the spray area of the jet, it is necessary to scan the jet nozzle over the workpiece in order to clean and deburr a large workpiece.

In order to efficiently clean and deburr especially large workpieces, conventional methods used multiple jet nozzles and moved the workpiece in a direction perpendicular to the row of jet nozzles.

However, when such multiple nozzles are used, the pump discharge amount that sends out the jet stream increases,
There are disadvantages in that the power input to pumps and the like increases, resulting in power loss and increased operating costs.

(Objective of the Invention) The present invention was made in view of the above circumstances, and it is an object of the present invention to efficiently clean and deburr a wide workpiece using a small number of jet nozzles without increasing the pump discharge amount. The purpose of the present invention is to provide a workpiece cleaning paper deburring device that can clean and deburr a workpiece.

(Structure of the Invention) According to the present invention, the object is to provide a workpiece moving means for moving a workpiece in one direction, a nozzle for injecting an ultra-high-pressure jet stream onto the workpiece, and a nozzle for injecting an ultra-high-pressure jet stream toward the workpiece, and a Workpiece cleaning and deburring characterized by comprising a nozzle rotation means for rotating and scanning the nozzle in a plane orthogonal to each other, and a nozzle reciprocating means for reciprocating the nozzle rotation means in a direction intersecting the moving direction of the workpiece. This is accomplished by a device.

The n-line sectional view and FIG. 3 are the same <m-m line sectional views.

In these figures, reference numeral 10 is a base. This base 1
There are two parallel guide rails 12 near the upper side edge of 0.
．． 12 are provided. A reciprocating table 14 is disposed above the base 10 so that one side of the reciprocating table 14 extends from the protruding end 10a of the base 10 (towards the right in FIG. 1). The guide rails 12 are located at the lower part near both side edges of the moving table 14.
A linear bearing 16.16 that slides on the moving table 14 is installed, and a nut 18 is installed near the center of the lower part of the moving table 14.
is fixed. This nut 18 is threaded onto a screw shaft 22 provided on the top of the base 10 via a bracket 20. This screw shaft 22 is rotationally driven by a motor 24 attached to the bracket 20.
The movable table 14 is slid along the guide rail 12 in the left-right direction in FIG. A microswitch (not shown) is provided at the four ends of the movement a of the moving table 14, and when the moving table 14 reaches the end of the moving range, the motor 24 is reversed and the moving table 1
Move 4 in the opposite direction. As described above, the nozzle reciprocating means of this embodiment includes the movable table 14, the guide rail 12 for reciprocating the same, the linear bearing 14, and the nut 18.
, a screw shaft 22, a motor 24, etc.

A nozzle rotating means 26 is provided at the end portion 14a of the movable table extending from the top end portion 10a of the base. In other words, a rotating cylindrical body 32 is installed via a bearing 30 in the outer case 28 that is attached to vertically penetrate the end portion 14a.
is rotatably held, and a pulley 34 is coaxially fixed to the upper part of the pulley 34 by a port 36. The pulley 34 and the rotating cylindrical body 32, which rotate together, are provided with a nozzle insertion hole 38 that communicates with and penetrates each other at a position of an axis B that is eccentric to the rotation axis A, and a jet inserted into the nozzle insertion hole 38 The nozzle 40 is a bearing 4 provided on the rotating cylindrical body 32.
2, it is rotatably held. On the other hand, a pulley 46 is rotatably held by a bracket 44 above the movable table 14, and a rotating belt 48 is wound between the pulleys 34 and 46. 50 is a motor that rotates the boule 46, and this motor 50 rotates the pulley 46. The nozzle 40 is rotationally driven via the belt 48 and pulley 34. Reference numeral 52 denotes a water supply hose that supplies ultra-high pressure water to the nozzle 40.

Reference numeral 54 denotes a belt conveyor as a workpiece moving means provided at the lower part of the base protrusion 10a. This conveyor 54 is located below the nozzle 40 at the end portion 14a of the movable table, and moves the alligator 56 in a direction perpendicular to the reciprocating direction of the movable table 14 (vertical direction in FIG. 1). Note that 58 is a motor that drives the conveyor 54.

Next, the operation of this embodiment will be explained.

First, the unprocessed workpiece is placed on the conveyor 54, and the motor 58
and move it in the direction of the arrow in Figure 1. Also, the motor 24
The movable table 14 is reciprocated in the left-right direction in FIG. Along with this reciprocating movement, the motor 50 is also driven to rotate the nozzle 40. In this state, a discharge pump (not shown) is driven to inject an ultra-high pressure water jet onto the workpiece 56 from the nozzle 40. As a result, the ultra-high pressure water jet sprayed from the nozzle 40 is sprayed and scanned over the workpiece 56 in a zigzag and spiral trajectory as shown in FIG. 1, thereby cleaning and deburring the workpiece 56. It turns out.

In this way, the ultra-high pressure jet stream is sprayed onto the workpiece 56 in a zigzag pattern while drawing a helical pattern.
The energy density of the ultra-high pressure jet stream becomes almost uniform, and the workpiece 56 can be cleaned and deburred evenly. Furthermore, since the entire surface of the large workpiece 56 can be treated with one nozzle 40, there is no need to use a plurality of nozzles 40, and the pump that delivers ultra-high pressure water may have a small water delivery capacity. Note that the nozzle 40 is connected to the pulley 3 by a bearing 42.
4 etc., the water supply hose 52 does not rotate during rotation.

In this embodiment, the nozzle reciprocating means is reciprocated by the screw 22 and the nut 18, but the screw 22 may be a so-called diamond screw (reverse screw) in which the screw grooves are formed in opposite directions. There is no need to use a microswitch to reversely rotate the motor 24 as in this embodiment, and a cam mechanism or an air cylinder is used instead of a screw and nut.
4 may be moved back and forth.

Further, the nozzle reciprocating means is not limited to one that reciprocates linearly as in the embodiment, but may be one that swings the movable table end 14a in an arc shape with the opposite side thereof as an axis. In this case, it goes without saying that the workpiece moving means 54 moves the workpiece 56 in the left-right direction in FIG.

In the embodiment, the reciprocating direction of the moving table 14 and the transfer direction of the workpiece moving means 54 are substantially perpendicular to each other, but the present invention is not limited to this, and it is sufficient that the two directions intersect with each other. If they are substantially orthogonal as in this embodiment, a wide workpiece can be cleaned and deburred most efficiently.

The ultra-high pressure liquid sprayed from the nozzle is not limited to water;
Of course, an appropriate solvent such as an organic solvent may be used depending on the material of the workpiece and the purpose of use.

(Effects of the Invention) As described above, in the present invention, the workpiece is moved in a direction intersecting the reciprocating direction of the nozzle with respect to the ultra-high pressure injection nozzle that rotates and reciprocates, so there is no need to increase the pump discharge amount. , wide workpieces can be efficiently cleaned and deburred using a small number of jet nozzles.
