Abstract

PURPOSE:To delete a preparing work before operating a board supplying device by directly stacking and placing boards on an elevation plate, raising the plate until a position detector detects the board, and pushing out one board of the uppermost side by a pusher simultaneously upon stopping of the plate. CONSTITUTION:Boards 1 stacked and placed directly on an elevation plate 2 are driven by a motor 8, raised until a position detection signal 5 is detected, and then stopped. When the plate 2 is stopped, the board l is simultaneously pushed to a supply side by a pusher 4 having a step at its end. In this case, a stopper 3 passes only the board l of the uppermost side, and set at a position for receiving the ends of second or lower boards l.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a substrate supply device for supplying substrates.

[Conventional technology]

Conventional substrate supply has used a vacuum suction supply method. However, with the recent high-density mounting of components, the number of boards with all grid holes and deformed boards as shown in Figure 4 has increased.
As shown in FIG. 5, the board 1 stored in the board storage box 7
A method is used in which the pusher 4 is used to push out the material. A related device of this type is described in, for example, Japanese Patent Laid-Open No. 63-209200.

[Problem to be solved by the invention]

However, in the board supply method using a board storage box as in the above-mentioned conventional technology, it is necessary to change the width of the board storage box every time the type of electronic package changes. The work was inefficient because it required a lot of setup work.

SUMMARY OF THE INVENTION An object of the present invention is to provide a substrate supply device that enables reduction of setup work before operating the substrate supply device.

[Means to solve the problem]

The object of the present invention is to provide an elevating plate on which a substrate is placed and move up and down, a position detecting means for detecting the upper surface of the substrate, and a position detecting means that detects when the elevating plate is stopped at a predetermined position. It consists of a pusher that pushes the substrate horizontally, a stopper that holds down the substrate placed below the substrate to be taken out, and a control device that controls the operation of the elevating plate and the pusher. This is achieved by lifting the elevating plate until the means detects the substrate and then controlling the pusher to push out.

[Effect]

When substrates are directly stacked and mounted on the lift plate, the lift plate rises until the 1-position detector detects the substrate. When the position detector detects a substrate, the elevating plate stops and at the same time, the pusher pushes out and supplies the topmost substrate.

At this time, the stopper receives the end surface of the board of the second stage and below,
Prevent the supply of multiple sheets.

Thereby, it is possible to supply a board with all grid holes, and it is also possible to reduce pre-setup work.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

Figure 1 shows the entire device.
a lifting plate 2 that moves up and down and is equipped with a board 1, a position detector 5 that detects the supply position on the top surface of the board 1, a pusher 4 that pushes the board 1 toward the supply side at the supply position, and a The control device i6 controls the pusher 4 and the motor 8 of the elevating plate 2 based on a signal received from the position detector 5.

Next, a detailed explanation of the operation will be given. The board 1 stacked directly on the upper surface of the elevating plate 2 is driven by a motor 8.
It rises and stops until the position detection signal 5 shown in FIG. 2(b) is detected. When the elevating plate 2 stops, the substrate 1 is pushed toward the supply side by a pusher 4 having a step at the tip shown in FIG. At this time, the stopper 3 is set at a position that allows only the uppermost substrate 1 to pass through and receives the end surfaces of the substrates 1 on the second and lower tiers.

Further, when the pusher 4 is pushed all the way, it contracts and returns to the initial state, repeating the above process to supply the substrate.

〔Effect of the invention〕

According to the present invention, even for a board with all lattice holes that cannot be used with a vacuum suction method, the board can be directly mounted on the elevator without using a board storage box. Setup work such as board storage is reduced.

In addition, it is possible to prevent substrate feeding failures due to errors in the interval between substrates being stored in the substrate storage box and the inclination of the substrate storage box.
