Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an electronic component insertion device used for mounting electronic circuit boards.

(b) Conventional technology In recent years, circuit board mounting work has become highly automated, and a wide variety of electronic components are now subject to automatic insertion. The conventional type of automatic insertion apparatus that has been the mainstream is the type described in Japanese Patent Publication No. 57-42238, in which the substrate is moved by an X-Y table and the insertion head is not moved. This type of insertion device is suitable for driving a large number of common axial lead type or radial lead type parts at high speed. By the way, recently, even parts that are only mounted on one or two boards are now subject to automatic insertion. Since it would be uneconomical to perform such a small amount of insertion work using the aforementioned high-speed insertion device, a relatively simple insertion device using an industrial robot was developed. Unexamined Japanese Patent Publication 1987-
Examples include those described in Japanese Patent Application Laid-open No. 199300 and Japanese Patent Application Laid-open No. 58-200600. Simply put, this type of insertion device consists of an arm of a rectangular coordinate robot with two axes, X and Y, an insertion head that picks up electronic components and inserts them into a board, and an insertion head that clinches component leads on the bottom surface of the board. The insertion work is carried out by moving the insertion head and the anvil head without moving the board.

(c) Problems to be solved by the invention The above-mentioned small electronic component insertion device has a structure in which a frame that moves in the X-axis direction is penetrated in the Y-axis direction by a shaft having a component mounting head and a shaft having an anvil head. It's summery. When the component mounting head and anvil head are drawn toward the frame, the shaft protrudes significantly behind the frame. For this reason, it was necessary to secure a space behind the frame to allow the shaft to retreat, necessitating a large installation space. The present invention aims to improve this point.

(d) Means for solving the problem In this invention, from a slide base that moves linearly in a horizontal plane, at right angles to the direction of movement and horizontally,
Make the upper and lower rails stick out. An upper slider and a lower slider each supporting an elevator are slidably supported on these rails. The elevator of the upper slider supports a component insertion chuck for inserting electronic components into a board disposed between the upper and lower rails. The elevator of the lower slider supports fixing means for applying a locking treatment to the component leads protruding from the lower surface of the board. A dedicated power source is provided for each of the upper slider and the lower slider.

(E) Function The component insertion chuck and the fixing means are given three-dimensional movement by the linear movement of the slide base, the linear movement of the slider, and the vertical movement of the elevator.
Perform the specified parts insertion and fixing work. Therefore, even if a component is inserted near the slide base, the slider will simply move toward the slide base, and nothing will protrude behind the slide base. Therefore, there is no need to provide extra space behind the slide base.

(f) Example In the figure, 1 is the direction perpendicular to the page (horizontal direction)
2 is a slide base that is slidably supported on a pair of rails 3 on the base 1;
is a feed screw that linearly moves the slide base 2 along the rail 3 in a direction perpendicular to the plane of the paper (this is defined as the X-axis direction). Reference numeral 5 denotes a vertical mounting plate forming a part of the slide base 2, from which a pair of upper and lower rails 6 and 7 project horizontally, aligned in the vertical direction and spaced apart from each other. The protruding direction of the rails 6 and 7 is perpendicular to the moving direction of the slide base 2, and this is defined as the Y-axis direction. Between the rails 6 and 7 is a rail 1 that supports a circuit board 8 horizontally.
A pair of rails 9 are arranged to extend perpendicularly to the plane of the paper. Reference numeral 10 denotes a component supply section placed at a height midway between the rails 6 and 7, and 11 is an electronic component supplied from the component supply section 10 with a pair of leads 12 protruding from its lower surface. The rail 6 is connected to the upper slider 13
The rails 7 slidably support the lower slider 14, respectively. An elevator 16 is supported on the side surface of the upper slider 13 by a pair of vertical guides 15 so as to be movable up and down. elevator 1
6 also serves as a casing for the parts insertion chuck 17,
It is moved up and down by an air cylinder 18 attached to the upper slider 13. An elevator housing 19 is fixed to the side surface of the lower slider 14, from which an elevator 20 projects upward. The elevator 20 is moved up and down by an air cylinder built into the elevator housing 19. elevator 20
also serves as a casing for the clinch lever 21. The movement in the Y-axis direction is given to the upper slider 13 by:
This is a feed screw 23 supported between an end plate 22 fixed to the rail 6 and the mounting plate 5. Lower slider 1
4 is moved in the Y-axis direction by a feed screw 25 supported between an end plate 24 fixed to the rail 7 and a mounting plate 5. The end of the feed screw 23 is attached to the mounting plate 5
The timing pulley 26 is fixed here. The timing pulley 26 is connected by a timing belt 29 to a shaft end timing pulley 28 of an electric motor 27 fixed to the mounting plate 5.
A timing pulley 30 is also fixed to the end of the feed screw 25, and is connected by a timing belt 33 to a shaft end timing pulley 32 of an electric motor 31 fixed to the mounting plate 5.

The above device operates as follows. First, the upper slider 13 is positioned above the component supply section 10. The lower slider 14 is a clinch lever 21
Since it is at a height that interferes with the component supply section 10, it is far away from the component supply section 10. Here, the elevator 16 moves up and down and picks up the component 11 with the component insertion chuck 17 (FIG. 1). Next, the upper slider 13 and the lower slider 14 move to align with a predetermined position on the board 8, and when they reach the target position, the elevator 16 descends and inserts the lead 12 of the component 11 into the hole in the board 8. Then, the elevator 20 goes up, and the clinch lever 21 bends the lead 12 protruding from the bottom surface of the substrate 8 to prevent it from coming off (FIG. 2). The same operation is repeated thereafter.

(g) Effects of the invention In this invention, the slider that moves along the rail protruding from the slide base provides movement in the Y-axis direction to the component insertion chuck and the fixing means for preventing component lead removal. Since no member moves in or out behind the slide base as the means moves in the Y-axis direction, there is no need to secure extra space behind the slide base, and space for installing the device can be saved. Also,
Since the upper slider and the lower slider move independently, it is possible to move only the upper slider above the component supply section. In other words, compared to a structure in which the component insertion chuck and the fixing means for preventing the component lead from coming out always move in vertical alignment, it is possible to assemble a thicker component supply section even if the heightwise distance between the chuck and the fixing means does not change. It becomes possible to match. This means that large parts can be easily supplied.
