Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention The present invention relates to a component positioning and assembling mechanism, and more particularly to a component positioning and assembling mechanism capable of positioning and assembling various electrical components on a printed circuit board at a predetermined angle.

BACKGROUND ART In recent years, there has been a demand for automatic printed circuit board assembly equipment that automatically incorporates electronic components, such as IC's, onto printed circuit boards. It consists of a chuck means for chucking parts, and an assembly mechanism for pressing and assembling the chucked parts onto a printed circuit board.For this reason, when assembling various electrical components, the electrical parts engineer must have a component positioning assembly mechanism. In addition, the chucked parts are placed at predetermined positions on the grid board, and the degree of intervention must be adjusted frequently. For example, when placing the VL number leads of an IC on the multi-terminal pattern of the board with high accuracy, if the IC is tilted from the plane, the terminal pattern and leads must be positioned accurately, so Jl is especially important. be.

OBJECTS OF THE INVENTION An object of the present invention is to eliminate the above-mentioned problems of the prior art, and to provide a positioning and assembling mechanism for assembling electrical components of various shapes onto a printed circuit board. It is an object of the present invention to provide a positioning mechanism in which a chuck part is formed on a single position correction mechanism.

General Summary of the Invention In order to achieve the above-mentioned object, the present invention provides a component positioning built-in mechanism using a square block having circular inner and outer circumferential surfaces and driven in an arcuate manner along the inner and outer circumferential surfaces. , an arm extending from the inner circumferential surface of the corner protrusion toward the center of the arc, a cough arm turntable, and support means for vertically movably supporting each of the parts. .

An embodiment of the invention An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is an overall perspective structural view of the component positioning assembly mechanism in this embodiment, FIG. 2 is a plan view of FIG. 1, and FIG. 3 is a side sectional view.

Mechanism base 71 of the component positioning built-in mechanism shown in No. 11A
is the base of the assembly machine @7, and is engaged with a motor shaft 7B of a motor (not shown) provided at the top, and as the motor shaft rotates, it is guided by two mechanism base guides 79 and rotates in the Z-axis direction. Move up or down. The mechanism base 71
A head 80 is attached to the square flock attachment.

The corner block 72 is installed in the head 80.
Contains. The square block 72 is moved in the vertical direction (Z-axis direction) by moving the square block drive arm 74, which is still in contact with one end thereof, in the arm direction. ) on the XY plane around the central axis. Four square block sliding rollers 75 are attached to the top and bottom of the square block mounting door 80, and guide the square block 20 rotation movement. The square block driving arm 74 is
Motor attached to mechanism base 71 (not shown)
driven by. That is, the rotation of the motor is transmitted to the square block driving arm 74 via a coupler (not shown) that converts rotational movement into movement in the X direction. The rotation shaft 81 of the turntable 760 is fixed to the corner block 72, and the turntable 76 rotates around the rotation shaft 81. The turntable 76 has at least two
A gripper 77 is attached to the turntable 76, and an arm of a cylinder mechanism 75 is attached so as to freely rotate the turntable 76. turntable 760
One grip 77 is selected by rotation. Understood 7
The state in which 7 is selected means that the tip of the grasping 77 is facing downward and the tip of the coughing tip is vertical (facing in two axis directions).

Although the arm part is mainly shown, the support body (not shown) of the cylinder machine 75 is an air cylinder driven by a vacuum pump, and the support body (not shown) of the cylinder machine 75 is based on the actual measurement of the turntable 76. So, the corner.

7" o y / 72. The cylinder mechanism 75 and the support are articulated.

The X-direction component of the movement of the arm of the cylinder mechanism 75 is driven by the cylinder mechanism 75, and the Z-axis component is absorbed by the joint. The gripper 77 has a nozzle shape so that it can catch the parts 13 by vacuum suction.

Note that a spring is incorporated inside the nozzle of the first gripping hand 77.

-The vacuum suction overcame the elasticity of the spring and caught the part 13, but the part 13 that was attracted
When released, the component 15 is pressed against a predetermined position 2o on the printed circuit board 1o by the elasticity of the spring.

The component positioning assembly mechanism configured as described above operates as follows. First, the printed circuit board 10 is illustrated with the electrical component 15 chucked.

Move the board 100 to the left and right using the XY table.
A predetermined position 20 is located directly below the component 15. In this state, if an angular deviation between the stained part 15 and the predetermined position 20 is discovered by a television camera or the like (not shown), the viewing drive arm 74 is driven.

The positioning mechanism including the corner block 72 and the tar/tape N76 rotates and tilts about the central axis of the grasping hand 77 by an XY thousand-plane correction value Δθ. As a result, the electrical component 15 chucked in the grasping hand 77 is accurately positioned on the predetermined position 20, and then pushed to the predetermined position 20 by the rotation of the shaft 78.

In this embodiment, the arm of the $75 cylinder machine only moves along the extension line of the arm, but by adjusting the position, the cough arm can be attached to the turntable 76 by 760 rotations of the turntable. It is possible to create a joint with a large angle, and therefore the number of grasping hands 77 can be increased. If the arm is attached to the turntable 76 in a better way, the maximum rotation angle can be further increased.

For example, a gear with a small diameter is attached to the turntable coaxially with the turntable 76, a groove is formed at the tip of the arm to engage with the gear, and the linear movement of the cough arm is changed to 760 rotations of the turntable. .

Effects of the Invention As described above, according to the present invention, by including a component chuck mechanism compatible with a plurality of electrical components and a positioning mechanism rotatable around the central axis of the selected chuck mechanism, various types of electric components can be used. A component positioning mechanism can be provided that accurately positions and installs electrical components.
