Abstract

PURPOSE:To simply replace a head in response to type change of an electronic component by providing a presser for pressing a lead extended from the component from its side and controlling the position of the lead extended from the component, and providing drive means for pressing the presser to the lead at a body. CONSTITUTION:When a rod 7a protrudes, a roller 9 is moved down to push a retainer 17 outward. Then, a presser 15 is rotated inward with a pin 16 as a center to press lead L of an electronic component L sucked to a sucking unit 12, to bend the lead L to a vertical attitude, and to control the position. When the lead L is held by the presser 15 and inserted into an insertion hole 21 opened at a board 20, the corner (a) of its base end La is not engaged with the side 18a of position control means 18, the end La is moved down under the smooth guidance of the side 18a, and a lower end Lb is controlled at the position by a narrowest part (t) of the adjacent position control means 18, 18 to effectively insert the end Lb into the hole 21.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a transfer head device for electronic components, and in detail,
The present invention relates to means for making the head section freely replaceable depending on the type of electronic component in a transfer head device that inserts a lead extending from an electronic component into an insertion hole drilled in a board.

(Prior art) A transfer head device that mounts an electronic component on a board by inserting leads extending from the electronic component into insertion holes drilled in the board has a mounting head on both sides of a suction section for the electronic component. , a pusher is provided which is pressed against the lead to regulate the position of the lead.

(Issue R' to be solved by the invention) The above-mentioned suction part and presser must be replaced as appropriate in response to changes in the type of electronic parts1.However, conventionally, the suction part and presser can be easily replaced. Since there was no way to do this, there was a problem in that the replacement work required a great deal of effort.

Therefore, the present invention responds to changes in the types of electronic components,
It is an object of the present invention to provide a means for easily and automatically replacing a suction part and a presser.

(Means for Solving the Problems) According to the present invention, a transfer head device is formed separately into a main body portion and a head portion. By providing the main body with a retainer that is driven by the drive unit and removably engages with the engaging portion of the head, the head is removably attached to the lower part of the main body. Pressure elements are provided on both sides of the suction section for the electronic component provided on the lower surface of the head portion to press the lead extending from the electronic component from the side to regulate the position of the lead, and the body portion A driving means for pressing the presser against the reed is provided.

(Function) In the above configuration, the head section can be easily attached to and detached from the main body section by driving the driving section to engage and disengage the engager of the main body section with the engaging section of the head section. Further, by driving the driving means, the presser is pressed against the lead portion of the electronic component attracted to the suction portion, the position thereof is regulated, and the lead is inserted into the insertion hole of the board.

(Example) Next, the present invention will be described in detail with reference to the drawings.

1 and 2 are a front view and a side view of the transfer head device. This transfer hand device WA is constructed by separately forming a main body part B and a head part C, and attaching the head part C to the lower part of the main body part B.

The main body part B is formed by punching a suction hole 2 in the center of the main body block 1. 3 on both sides of the main block 1,
It is an arm-shaped engager that is rotatably attached to the pin 4. This engaging element 3 is urged inward by a coil spring 5. Cylinder 6 as a driving part is arranged on both sides of the main body block 1, and when the rod of this cylinder 6 protrudes, the engager 3 expands outward against the spring force of the spring 5.

The head section C has a base plate 11 mounted on the lower surface of the main body 10, and a suction section 12 for the electronic component P on the lower surface of the base plate 11.
(See also Figure 3). Adsorption part 1
A suction hole 13 communicating with the suction hole 2 is formed in the suction hole 2 .

A lead L extends from the electronic component P, and the electronic component P is mounted by inserting the lead L into an insertion hole drilled in a board. Groove-shaped engaging portions 14 are recessed on both sides of the main body 10 . The head portion C is removably attached to the lower part of the main body portion B by the engaging element 3 being removably engaged with the engaging portion 14 .

15 is a presser, and bottles 16 are provided on both sides of the suction part 12.
It is rotatably attached to the center.

In FIG. 1, an inclined receiving portion 17 is provided projecting from the upper part of the presser 15. As shown in FIG. Further, this pusher 15 is urged outward by a coil spring 28. The main body portion 1 is provided with a cylinder 7 as a driving means. The rod 7a of this cylinder 7 is an arm-shaped elevator 8.
A roller 9 that comes into contact with the receiving portion 17 is pivotally attached to the lower end of the elevator 8.

With the rod 7a retracted and the roller 9 rising, the presser 15 is expanded outward by the spring force of the spring 28. When the door a protrudes, the roller 9 descends and pushes the receiving part 17 outward. Then, the presser 15 rotates inward around the bottle 16, and the electronic component P sucked by the suction part 12
Press the lead L, bend the lead L into a vertical position, and adjust its position. At the lower edge of the presser 15, a position regulating means 1B for the lead L is formed.

As shown in FIG. 4, the front shape of the position regulating means 18 is triangular, and the side surface 18a thereof has a tapered shape projecting from the upper end toward the lower end. The lead consists of a wide base end La and an intermediate lower end Lb. Therefore, as shown in FIG. 5, when the lead L is held between the pressers 15 and inserted into the insertion hole 21 drilled in the substrate 2o, the corner a of the base end La is used for positioning. The base end La is not caught on the side surface 18a of the means 18, and the base end La smoothly descends while being guided by the side surface 18a, and the lower end Lb is connected to the adjacent position regulating means 18.
The position is regulated by the narrowest part t of 18, and the lower end part Lb can be reliably inserted into the insertion hole 21.

6 and 7 show other embodiments of the position regulating means 19. FIG. This position regulating means 19 has a continuous mountain shape, and the position of the lower end Lb is fixed at the narrowest part t, and the corner a is not caught on the wall surface of the position regulating means 19 and is smoothly guided downward. Ru.

When the type of electronic component P is changed, the head portion C is replaced accordingly. This replacement can be easily performed because the head part C can be removed from the main body part B by driving the cylinder 6 to expand the engager 3 and separate it from the engaging part 14. Of course, this exchange can be pre-programmed and done automatically.

(Effects of the Invention) As explained above, in the present invention, the main body part and the head part are formed separately, and the main part is driven by the drive part to removably engage with the engaging part of the head part. By providing an engaging element, this head part can be detachably attached to the lower part of the main body part, and leads extending from this electronic component can be attached to both sides of the suction part of the electronic component provided on the lower surface of the head part. A pusher is provided to press from which direction to regulate the position of the lead, and a drive means is provided in the main body to press the pusher against the lead. The head part can be easily replaced.
