Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a board supplying and unloading device suitable for supplying and unloading printed circuit boards.

[Technical background of the invention and its problems] There have been various devices for mounting electronic components onto a printed circuit board (hereinafter referred to as a board) by, for example, insertion.
The invention described in Publication No. 12565 applies a thin plate supply/takeout device to an electrical component insertion machine that mounts electrical components onto a board. In other words, a positioner (positioning table) is installed at a processing position for inserting and positioning the board, and a supply conveyor is installed on one side of the positioner (positioning table), and an unloading conveyor is installed on the other side.
A supply conveyor transports the substrate and sends it to a positioner, where it is positioned and processed, and then a carry-out conveyor carries out the board and stores it in a storage box. When substrates are being supplied to and taken out from the positioner, the transport surfaces of both conveyors are at the same height as the top surface of the positioner, and the positioner positions the substrate by moving two-dimensionally, front to back, left and right, during work. Sometimes both conveyors are moved upwards so that they do not interfere with the operation of the positioner. Therefore, since each substrate is repeatedly moved up and down after being conveyed, it becomes mechanically complex, and there is a limit to the improvement in production speed.

[Purpose of the invention]

The present invention has been made in order to eliminate the above-mentioned disadvantages, and an object of the present invention is to provide a plate feeding and unloading device that has a simple structure and can improve production speed.

[Summary of the invention]

The present invention has a supply conveyor body provided on one side of a positioning table that holds a plate and positions it by moving it on a plane, and a discharge conveyor body provided on the other side of the positioning table. In the plate supply/unloading device for supplying the plate from the supply conveyor body to the positioning table and carrying it out by the carry-out conveyor body, the supply conveyor body and the carry-out conveyor body are arranged on respective plate conveying surfaces. are arranged so as to be on the same plane as the surface of the positioning table that holds the plate body, and each is driven by a first drive source to move forward and backward with respect to the positioning table, and the supply conveyor body is connected to the positioning table. While the supply conveyor body is being driven forward with respect to the positioning table, the plate body can be conveyed to a predetermined position of both conveyor bodies by a second driving source, respectively, while the supply conveyor body is being driven backward with respect to the positioning table. The present invention provides a device for supplying and discharging plates.

[Embodiments of the invention]

The details of the present invention will be explained below with reference to an embodiment shown in FIGS. 1 and 2.

In this embodiment, the present invention is applied to a board assembly device 1 that inserts and mounts electronic components on a board. The substrate 4 is held and driven along the water surface to position the substrate 4. The present embodiment is comprised of a supply conveyor mechanism 11 provided on one side of the positioning table 2, an unloading conveyor mechanism 12 provided on the other side, and a substrate transfer 13. Furthermore, the supply conveyor mechanism 11
On the right side of FIG. 1, there is provided a supply magazine (not shown) that accommodates a large number of substrates 4 spaced apart and stacked, and on the left side of the carry-out conveyor mechanism 12, there is a similar storage magazine (not shown). ) is provided.

The supply conveyor mechanism 11 includes a frame body 17 having a pair of supporting walls 15 and 16 spaced apart from each other, a moving body 18 attached below the frame body 17, and a guide groove body movably guiding the frame body 18 in the direction of the arrow 19. 20
, a pair of supply conveyor bodies 21 and 22 attached to the inner surfaces of the support walls 15 and 16, rails 23 and 24, and an air cylinder device (first drive source)
It consists of 25. and supply conveyor body 2
1 and 22 have belts 26 and 27 running along rails 23 and 24, and are driven by motors (second drive sources) 29 and 30.

The delivery conveyor mechanism 12 is the supply conveyor mechanism 11
The configuration is similar to that, and the same parts are denoted by the same numbers and the letter "a", so a detailed explanation will be omitted.

The substrate transfer 13 is of a generally known mechanism and is therefore shown schematically. This is main body 35
Four gripping claws 36, . This main body 35 is moved by a mechanism (not shown) as indicated by the four arrows shown in FIG.

Next, the operation of this device will be explained. In the initial state, the supply conveyor mechanism 11 is connected to the air cylinder device 2.
5 moves back, the frame body 17 moves to the right,
The frame body 17a of the carry-out conveyor mechanism 12 is also located at the position indicated by the two-dot chain line on the left. Now, when one substrate 4 is supplied from a supply magazine (not shown) to the right end of the supply conveyor body 21, the belt 26,
27 runs on rails 23 and 24, and the board 4 riding on it is sent to the positioning table 2. At the same time, the entire frame body 17 moves to the left due to the advance of the air cylinder device 25, and eventually the board 4 is fed. The positioning table 2 is conveyed by the conveyor body 21 and moved by the advancement of the frame body 17.
Stops near. At this point, the substrate transfer 13 descends and grips the substrate 4 with the claws 36,
It continues to move to the left, carries the substrate 4 to a predetermined position on the positioning table 2, releases it, ascends, and returns to its original position. During this time, the supply conveyor body 21 and the discharge conveyor body 2 are moved back due to the retreat of the air cylinder device 25.
1a is located at a distance from the positioning table 2. Thereby, the positioning table 2 can be positioned without any trouble. When the processing is completed, the next substrate 4 is supplied again in the same manner as described above, and is fed and stopped near the positioning table 2. On the other hand, in the carry-out conveyor mechanism 12, the carry-out conveyor body 21 is moved forward by the air cylinder device 25a.
A moves to the right and waits at a position where the belt 26a runs near the positioning table 2. Subsequently, when the next substrate 4 is carried by the transfer 13, the processed substrate 4 is pushed by this and placed on the belt 26a of the carry-out conveyor mechanism 12, and immediately carried out to the left, and then - Due to the operation of the cylinder device 25a, the entire carry-out conveyor body 21a also moves to the left, and the substrate 4 is placed in the storage magazine at its left end. As described above, processing is performed again with both conveyor bodies 21, 21a separated (moved to the right and left), and these operations are repeated thereafter.

〔Effect of the invention〕

As described in detail above, the plate supply/unloading device of the present invention has a supply conveyor body for supplying plates on one side of the positioning table, a discharge conveyor body on the other side, and both conveyor bodies. Since it is configured to move forward and backward relative to the positioning table, during processing on the positioning table, there is no need to move both conveyors upwards or downwards, but only in the horizontal direction.This allows for a simple configuration and increases production speed. This has the effect of improving.

In this embodiment, an air cylinder device was used to advance and retreat the conveyor body, but other mechanisms may be used, and the plate body is not limited to circuit boards, but can also be used to supply other components using a positioning table. It may also be an unloading device.
