Abstract

PROBLEM TO BE SOLVED: To make microcomponents which even a less skilled worker can mount by realizing a jig having a components pick up function at one end and vertical moving arm having a lower end stopper mechanism to restrict the moving range of a shaft; the jig being mounted on the top end of a horizontal multi-joint link. SOLUTION: A worker moves a movable guide VG to a microcomponent CP mounting position on a printed board PB, grips an operating knob AT of the guide VG and lowers a vertical shaft VA to a position where a lower end stopper ST stops it. After fine adjusting to exactly align a lead terminal of the microcomponent CP with a cream solder position on a wiring of the printed board PB, an operating switch FS of a pickup nozzle PU is turned off to release sucking of the pickup nozzle PU. Thus a less skilled worker can mount the component always accurately.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a micro component hand mounting apparatus used as a jig when a micro component is manually attached to a printed board.

[0002]

Recently, the degree of integration of semiconductor integrated circuits has increased, and small and high-density products have been developed. As a result, related components such as resistors and capacitors have also been reduced in size. The degree is progressing rapidly. For this reason, the printed circuit board on which these components are mounted is also very delicate because the wiring density of the circuit is increased.

When a product is manufactured using such small components, a high-precision dedicated component mounting machine, such as a chip mounter, is used to mount components accurately. At this stage, the current situation is that components must be mounted manually.

[0004] However, in the case of micro components, due to the increase in the number of pins of the lead terminals and the reduction in pitch, when components are manually mounted, hand shaking and instability of position holding occur, so that a solder bridge between the lead pins and the like is generated, so that a stable product is manufactured. Things are getting harder. For this reason, the person in charge of the department in charge of product prototypes using micro parts is required to have extremely high skills, but few people satisfy them, which is a bottleneck in product development and trial production.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a vertical operating shaft having a lower end stopper mechanism which is attached to the tip of a horizontal articulated link and has a component pick-up function at one end thereof and limits the range of movement to the lower end of the shaft. By realizing a jig and tool having the configuration described above, it is possible to easily mount a micro component even for a person without advanced skills.

The first joint LN1 and the second joint LN2 are provided with load adjusters LC1 and LC2, respectively. VG
Is a vertical operating arm, VA is its vertical axis, and ST is a lower end stopper of the vertical axis. AT is an operation knob attached to the vertical axis VA, and PU is a pickup nozzle attached to the tip of the vertical axis VA. The vertical movable guide VG is attached to the second arm AM2 of the horizontal link so that its vertical axis VA is perpendicular to the surface of the work table DS. FS is a foot-operated switch for operating the pickup nozzle PU.

[0009] CP is a micro component, and PB is a printed board to which the micro component CP is attached. PL is a pallet in which minute components are stored. The operation of the micro component hand mounting device of the present invention thus configured will be described below.

A printed board PB on which the minute parts CP are mounted is placed on the work table DS.
The micro component CP attached to B is stored and placed on the pallet PL. The first arm AM1 of the horizontal link and the second arm AM2 of the horizontal link can move the vertical movable guide VG horizontally to the surface of the work table DS by the operation knob AT attached to the vertical axis VA.

When the moving range of the first arm AM1 and the second arm AM2 is exceeded, the base BS of the hand mounting device can be moved on the linear guide rail L to expand the range. The vertical movable guide VG can be moved to an arbitrary position on the surface of the work table DS, so that the work can be performed regardless of the position of the printed board PB on the work table DS.

The procedure for mounting the microparts is as follows. The operator holds the operation knob AT of the movable guide VG, moves the movable guide VG onto the pallet PL, lowers the vertical axis VA of the movable guide VG, and moves the pickup nozzle P
U is brought over the micro component CP of the pallet PL, the vertical axis VA of the movable guide VG is lowered until the pickup nozzle PU comes into contact with the micro component CP, and then the operation switch FS of the pickup nozzle PU is turned on, so that the micro component CP is adsorbed to pickup nozzle PU.

When the micro component CP is attracted to the pickup nozzle PU, the worker raises the vertical axis VA of the movable guide VG to lift the micro component CP, and moves the operating arm VG above the mounting position of the printed board PB. . Micro parts CP
Is sucked by the pickup nozzle PU attached to the tip of the vertical axis VA, and is carried to an arbitrary position on the printed board PB in a state as shown in FIG.

In this case. The load adjustment units LC1 and L are connected to the first joint LN1 of the horizontal link and the second joint LN2 of the horizontal link.
Since C2 is provided, by adjusting this,
The torque, which is the operating force for moving the operating arm VG by the operation knob AT, can be adjusted to such an extent that the movable guide VG is not moved by its own weight after moving the movable guide VG to the mounting position of the micro component CP on the printed board PB.

That is, the load adjusting units LC1, LC2 of the first joint LN1 of the horizontal link and the second joint LN2 of the horizontal link.
Can be set so as to have an optimal operation force capable of holding the movable guide VG after the end of positioning, so that any adjustment can be made in advance so that anybody can be affected by hand shake and the like. The delicate position of the movable guide VG can be accurately set without receiving any.

Next, an operation for mounting the micro component CP on the printed board PB will be described. After moving the movable guide VG to the mounting position of the micro component CP of the printed board PB, the operator holds the operation knob AT of the movable guide VG, and sets the vertical axis VA to the lower end of the vertical axis as shown in FIG. The vertical axis is lowered to a position where the vertical axis is stopped by the stopper ST.

At this time, the position of the lower end stopper ST of the vertical axis is, as shown in FIG. 2B, between the lead terminal LD of the micro component CP and the upper surface of the cream solder CS placed on the wiring of the printed board PB. The distance is set in advance and adjusted so that the clearance is 0.3 mm to 0.5 mm and which clearance can be obtained.

The operator makes a fine adjustment so that the position of the cream solder CS placed on the wiring of the printed board PB and the lead terminal LD of the micro component CP exactly match. When this operation is completed, the pickup nozzle PU By turning off the operation switch FS to release the suction of the pickup nozzle PU, the minute component CP can be accurately mounted on the wiring of the printed board PB.
