Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component mounting machine and the like for separating and conveying printed boards, which are supplied in a continuous row, one by one.

Configuration of Conventional Example and Problems Thereof A conventional printed circuit board separating and conveying apparatus has a printed circuit board 2 supplied on a conveyor 1 which guides and conveys both left and right ends of the printed circuit board, as shown in FIG. Is stopped by the stopper 3. At this time, the separation plate 4 enters below the top substrate from the downstream side by the length of the top substrate, and then ascends so that the top substrate is lifted from the conveyor and separated from the conveyor to be placed on the separation plate. . If the separating plate is moved forward in this state, one leading substrate is separated and is carried downstream. Subsequent substrates move forward by the forward force of the conveyor and stop at the stopper. The separation plate 4 descends on the take-out rail 5 after advancing, and transfers the leading substrate onto the take-out rail 5, thereby separating the substrates.

However, in the above-described substrate separating / conveying device, in order to convey substrates of different lengths, the distance of the separating plate to enter below the leading substrate must be changed, which complicates the mechanism. Also, as the separating speed increases, the rising speed of the separating plate also increases, and the impact of the separating plate hitting the bottom of the leading substrate increases, so the impact causes the leading substrate to bounce and the printed circuit board may tilt. However, it has a defect that it pops out of the apparatus and normal separation is not performed.

An object of the present invention is to solve the above-mentioned drawbacks, and to provide a printed circuit board separating / conveying apparatus which simplifies the structure and performs high-speed separation in response to a change in the length of the board.

Configuration of the Invention The present invention is a conveyor for supporting and carrying a continuous printed circuit board on both sides along the carrying direction, and abutting on the front end of the printed circuit board in the middle of the conveyor in the carrying direction, At the position sandwiched between the stopper that stops the printed circuit board at the tip and the conveyor, it is adsorbed on the back surface of the front end of the cutting edge printed circuit board, lifted and separated, and moved back and forth along the transport direction. It is composed of a pad and a take-out rail for placing the separated cutting-edge printed circuit board. Separation can be performed only by moving the suction pad up and down and back and forth. Further, when the front substrate adsorbed by the suction pad advances, the subsequent substrate is conveyed by the downstream end face of the suction substrate, so that the substrate to be separated can be moved forward and the subsequent substrate can be fed at the same time. You can increase the speed. Further, when the suction pad rises and hits the leading substrate, the suction force works, so the impact force at the time of the rise becomes small, and the substrate does not bounce. It also has the feature that it can respond to changes in the substrate length.

Description of Embodiments One embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a perspective view showing a state before separation according to the embodiment of the present invention. In FIG. 2, reference numeral 6 is a conveyer for feeding the substrate from left to right in the figure. 7 is a printed circuit board to be separated,
8 is a subsequent substrate, and the flow is stopped by the stopper of 9. Further, 10 is a suction pad for separating this,
Reference numeral 11 is a take-out rail that guides the separated substrate.
FIG. 3 shows a state immediately after the front substrate is lifted by the suction pad.

The operation of the printed board separating and conveying apparatus of the present invention will be described below.

The continuous printed circuit board is in a state where the flow is stopped by the stopper 9 while predicting the forward force by the conveyor 6. At this time, the suction pad 10 is made to enter below the downstream side of the leading substrate from the downstream side, and then the suction pad 10 is raised. The front substrate is lifted by the suction pad 10 on the downstream side above the stopper 9. After that, by advancing the suction pad 10, one head substrate is separated and is carried to the downstream. At this time, since the subsequent substrate is given a forward force by the conveyor, it moves forward in accordance with the forward movement of the leading substrate and stops at the stopper. After advancing, the suction pad 10 descends on the take-out rail, and the front substrate 7 can be transferred onto the take-out rail 11 by eliminating the suction force. Even if the length of the board changes, the suction pad 10 is applied only to the downstream end of the printed board, so that the same operation can be performed.

Effects of the Invention As described above, according to the present invention, the separation method, which has been the biggest impediment factor in accelerating the loading operation of the printed circuit board, can be greatly improved. Moreover, since the front end is sucked, even if the dimension of the printed circuit board in the conveyance direction is changed, it is possible to always pick up and move a fixed size position from the stop position, and since only the front end is lifted and transferred, The leading edge of the printed circuit board can be transferred without friction between the rear end and the front end of the subsequent printed circuit board due to relative movement in the vertical direction, and the posture of the subsequent printed circuit board is kept stable. Therefore, the practical effect is great.
