Abstract

PURPOSE:To make a parts insertion head for an automatic electronic parts insertion device compact and to make it easy to constitute a multi-head by uniting a parts inserter and a driving mechanism to open and close the inserted and by so constituting the mechanism as to make it possible to vertically move. CONSTITUTION:Introduction of air from an airport 30 for closing the inserter moves a cylinder rod 29 downward. By this movement, rollers 27 are contacted with the taper and thick end of the cylinder rod 29 resisting the force of a springs 25 and are pushed toward outer sides to cause arms 13 to make a minute rotation around shafts 22 for closing a inserter 11 to hold a part 34. Then, a base 16 vertically travels by the drive of an aircylinder 20 along the shafts 18 fixed to a frame 19. This constitution makes it easy to constitute a compact multi-head.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a component insertion head that can be used in automatic electronic component insertion devices and the like.

Configuration of conventional examples and their problems None of the conventional component insertion heads has the three functions of holding/removing inserted components twice and moving up and down, so it is necessary to develop a small-sized insertion head that has these multiple functions. was desired.

Purpose of the Invention The present invention solves the above-mentioned conventional problems, and has three functions: time retention/removal of the inserted part by 9 rotations, and up/down movement, and is also compact and lightweight, and can be used in a multiple-hand configuration. The purpose is to provide a suitable component insertion head.

Composition of the Invention The component insertion head according to Book 4eF4 holds and holds inserted components.
An inserter that removes the inserter, an inserter opening/closing drive unit for driving the inserter to open and close, a rotational drive unit for rotationally driving the inserter opening/closing drive unit, and a base to which the rotational drive unit is fixed. The inserter is equipped with a vertical drive unit for moving the inserter, and has three types: an opening/closing drive, a rotation drive, and a vertical drive.
A unitized insertion head having two functions can be obtained, and an insertion head that is compact in shape and easy to configure with multiple heads can be provided.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic view of a component insertion rod in an embodiment of the present invention. In the figure, reference numeral 11 denotes an inserter that can be opened and closed for holding parts, and is fixed to an arm 13 with a bolt 12.

Note that the inserter 11 can be replaced depending on the shape of the component.

The arm 13 is opened and closed by an opening/closing drive section 14 for driving the inserter 11 to open and close. The opening/closing drive unit 14 is a base 16
The rotary drive unit 15 is fixed to the shaft end of a rotary drive unit 15, which is a pneumatic rotary actuator fixed to the rotary actuator, and rotates. The rotation angle of the opening/closing drive unit 14 is determined by the rotation stopper 1.
7 is regulated. The base 16 to which the rotary drive unit 15 is fixed can slide up and down on two shafts 18 fixed to the frame 19.
The base 16 is fixed to the shaft end of an air cylinder 20 fixed to the air cylinder 9, and the base 16 moves up and down according to the movement of the air cylinder 20. It is attached to the frame 19 with 21 lower limit stopper bolts, which regulates the lower limit position of the base 16, and can be adjusted according to the insertion height.

Furthermore, the air cylinder 20 is located at the center of the two slide shafts 18;
By shifting the center position of the block consisting of the inserter 11, the opening/closing drive section 14, and the rotation drive section 16 from the position o, the inside size of the head can be reduced to about 50 degrees, making it possible to support multiple heads. did it.

Next, the opening/closing drive unit 14 of the inserter 11 will be explained. In FIG. 2, the inserter 11 is connected to the arm 1 by the port 12.
It is attached to 3. The arm 13 can perform minute rotational movements using a shaft 22 fixed to an opening/closing drive unit flange 35 that is rotated by a rotation drive unit 16 as a fulcrum. Further, the arm 13 contains a compression spring 25, and the compression spring 25 is pressed by the spring press plates 2 and 4 fixed to the flange 36 with screws 23, so that the arm 13 is constantly moved in the direction in which the inserter 11 opens. Spring force is added.

In Figure 2, 29 is a cylinder rod, and the tip of the rod is tapered. Now, when air enters from the air port 31 for opening the inserter, it pushes up the cylinder rod 29 guided by the flange 35 and bushing 28, and pushes the arm 13 upward.
The roller 27 rotatably fixed by the pin 26 comes into contact with the thin end of the cylinder rod 29, and the arm 13 pushed by the compression spring 25 moves minutely around the shaft 22. The inserter 11 rotates, and the tip of the inserter 11 opens.

A case in which the inserter 11 opens will be explained in FIG. When air enters the inserter closing air boat 30, the cylinder rod 29 moves downward. Then, against the pressure of the spring 25, the thick tapered part of the cylinder rod 29 hits the roller 27 and pushes the roller 27 outward. Then, the arm 13 makes a slight rotational movement using the shaft 22 as a fulcrum, and the inserter 11 grips the closing part 34. Further, it is a stopper integrated with the 32vi base 16, and together with the external stopper 33, regulates the lower limit position.

This external stopper 33 can be raised and lowered to any desired feeding position, allowing electronic components 34 to be fed.

Effects of the Invention As described above, the insertion head of the present invention has three functions necessary for inserting parts: (1) holding and removing parts; (rotating parts);・It has a downward movement function and can be used in automatic insertion devices for electronic components. - Also, since it is small and lightweight, it can be used effectively with a multi-head insertion device having a high insertion capacity.
