Parts supply device

Abstract

The present invention provides a parts supply device, which is capable of accurately delivering the carrier strip by a destined spacing, and capable of positioning the carrier strip at a parts supply position. The parts supply device carries the carrier strip containing parts in concave of the destined spacing, and supplies the parts in turn, the parts supply device including: a strip feeding mechanism, which repeatly doing this feeding motion: according to the carrying route, making the feeding pin ascend to match with the feeding hole of the said carrier strip, making the feeding pin in this state progress to make the carrier strip move a destined feeding quantity, and then making the feeding pin descend and fall back to the former position; and a orientation mechanism, which repeatly doing this feeding motion: according to the carrying route of downstream side of the strip feeding mechanism, after the feeding pin finishes the progress through the strip feeding mechanism, making the feeding pin ascend to match with the feeding hole of the said carrier strip, and making the feeding pin descend after the feeding pin finishes the countermarch.

Description

technical field [0001] The present invention relates to a component supply device, and more particularly to a component supply device that supplies components to a component mounting device that mounts electronic components and the like on printed circuit boards, ceramic substrates, and the like. Background technique [0002] In a component mounting apparatus that automatically mounts electronic components and the like on a substrate, the components are conveyed and supplied to a predetermined supply position by a component supply device, wherein the components are accommodated in a carrier tape formed at predetermined intervals on a carrier tape closed by a cover tape. in the recess. [0003] As such a parts supply device, generally used is a device in which, as shown in the schematic diagram of FIG. The sprocket S is intermittently rotated to convey the carrier tape T from which the cover tape has been removed, and the components are sequentially supplied to the component...

AI Technical Summary

Problems solved by technology

[0006] However, in the case of feeding the carrier tape T through the sprocket S, when the tape T is fed approximately horizontally, since the number of pins P of the sprocket S actually engaged with the feed hole H is small , so there is a problem that when a load is applied to the tape T, the tape T is disengaged from the pin P, or the feed hole H of the tape T is deformed such that it becomes wider in the feed direction, and correct positional accuracy cannot be ensured.

Therefore, there is a problem that it is necessary to create a gap between the pin P of the sprocket S and the feed hole H of the belt to absorb the change in the feed pitch due to the difference in thickness. Conversely, due to its clearance, the positional accuracy of the feed cannot be ensured

[0008] In addition, in the case of sending out the carrier tape through the friction drive unit disclosed in the above-mentioned Patent Document 1, since the occurrence of slippage cannot be avoided, there is also a problem that the positional accuracy cannot be ensured.
