The present invention relates to a support device mounted to an electronic component inserter for inserting electronic components into a printed board, and in particular, to enable the advanced print substrate to be smoothly pulled out independently through a transport path, thereby preventing the printed board from being damaged. The present invention relates to a printed circuit board support device of an electronic component inserter that prevents and improves work efficiency.

BACKGROUND ART In general, a printed board is widely used in various electronic products by inserting a large amount of electronic components, and an electronic component inserter is known to automatically insert electronic components into such a printed board.

As shown in FIG. 1, the electronic component inserter 200 is positioned at the top end and pressurized at the tip of the operation cylinder 212a that is moved back and forth to feed and feed the printed circuit board Pa. A supply device unit 210 having a feed transfer platform 211 formed by installing a transfer operation means 212 formed at an upper portion of the operation plate 212b; It is located in the middle portion so as to be associated with the supply unit 210 has an insertion head 221 for inserting an electronic component in the printed board (Pa), the upper portion of the movable shelf 222 directly below the insertion head 221 An insertion device unit 220 installed horizontally and having a supporting means 223 in which the guide plate 223a and the position fixing tools 223b are disposed; Positioned at the rear side to be connected with the inserting device unit 220 and intermittent with the completed printed substrate Pb to place a new printed board Pa on the support means 223 of the inserting device unit 220. It was configured as a discharge device unit 230 having a discharge transport platform 231 is provided with a stopper 232 at a predetermined position.

Referring to the operation relationship of the electronic component inserter 200 as shown in FIG. 2, first, the supply of the discharge device unit 210, 230, in accordance with the support means 223 of the insertion device unit 220, When a new print board (Pa) is brought into the feed transfer platform 211 of the feeder unit 210 in a state where the discharge transfer platform 211 and 231 is lowered, the transfer operation means 212 moves forward to produce a new print. The substrate Pa is drawn toward the support means 223 of the inserting device 220.

At this time, the electronic component is already inserted in the inserting device unit 220 by a new printed board Pa, which is inserted into the supporting means 223 of the inserting device unit 220, and thus the completed component is positioned on the supporting means 223. When the printed board Pb is pushed out and pulled out and caught by the stopper 232 of the discharge transport platform 231, a new printed board Pa is positioned on the supporting means 223 of the inserting unit 220.

Thereafter, in a state in which a new printed board (Pa) fixed to the support means 223 of the inserting device unit 220 is fixed as the position fixing tool 223b, in a region set together with the insertion head 221 which is operated up and down. As the movable movable shelf 222 is organically operated, the operation of inserting an electronic component into a new printed board Pa mounted on the supporting means 223 on the upper movable shelf 222 is started.

On the other hand, before the operation of inserting the electronic component in the insertion device unit 220, the supply and discharge transfer platform 211, 231 is raised, the new feed substrate (Pa) is again in the supply transfer platform 211 The finished printed board Pb, which is brought in and waits to be inserted into the supporting means 223 of the inserting device unit 220, is drawn out on the discharge transfer platform 231 and the stopper 232 is terminated. When the discharge is carried out as the discharge platform 231 it was repeated to insert the electronic component in the printed board (Pa).

In the electronic component inserter 200 as described above, the support means 223 mounted on the inserting unit 220 does not have a structure capable of drawing or drawing the printed board Pa by itself, and the guide plate 223a. And the transfer operation means 212 which is pulsated as a piston type on the feed transfer platform 211 because it is configured to simply guide and position the printed board Pa to be fed and supplied as the position fixing tool 223b. The print board Pa can be pulled out from and pulled out depending on the stopper 232 installed at a predetermined position on the transfer platform 231, so that the print board Pa is placed on the supporting means 223 of the inserting unit 220. Malfunctions occur in the draw-out and draw-out, or the printed board Pa is damaged.
