Oblique-slip type feeding device

Abstract

The invention provides an oblique-slip type feeding device comprising a baseplate I, a baseplate II, a bevel blanking mechanism, a product pushout mechanism and a feeding guide rail mechanism. The bevel blanking mechanism comprises a support seat I, a support seat II, a support plate I, a support plate II, a guide bar I, a guide bar II, a guide bar III, a guide bar IV and a sliding plate; the product pushout mechanism comprises two linear sliding rails, a connecting plate, at least two push rods, and a driving mechanism used for driving the push rods to do linear reciprocating motion; and thefeeding guide rail mechanism comprises a guide rail mounting block I, a guide rail mounting block II, guide rails, a guide rail cover plate I, a guide rail cover plate II, a guide plate, a sensor mounting block I, a feeding in-position detection sensor, a sensor mounting block II, a bar stock feeding validation sensor and a baffle. According to the oblique-slip type feeding device stated in the invention, not only can products be pushed into a track in sequence, but also a large quantity of products can be loaded on a slope once. In this way, not only is the cost low, but also the feeding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of semiconductor component processing, in particular to an oblique slide feeding device. Background technique [0002] In the field of semiconductor component product processing, the automatic punching and forming system has various feeding forms. For common TO products, such as TO220, TO252, TO263, etc., the most commonly used feeding method is to use C-shaped material box and manipulator to grab this feeding method, because these products have a relatively large plastic package, and the entire material The strips are relatively flat in the material box. However, for TC-2, a product with a small plastic package and an asymmetric layout of the plastic package on the lead frame, it is obviously not feasible for the robot to grab it directly. The gap in the middle is too small, which is not conducive to gripping by the claws; second, the side of the plastic package is close to the product, and the plastic pa...

Problems solved by technology

However, for TC-2, a product with a small plastic package and an asymmetric layout of the plastic package on the lead frame, it is obviously not feasible for the robot to grab it directly. The gap in the middle is too small, which is not conducive to gripping by the claws; second, the side of the plastic package is close to the product, and the plastic package is very small, so when it is put into the material box, the material strips are all inclined in one direction, which is not conducive to the gripping of the jaws. crawl

There is also a rib cutting and forming system that uses toothed material boxes on the market, but with toothed material boxes, the strips need to be loaded into the toothed material box one by one, and generally the toothed material box can only be loaded with 20 pieces at a time. Therefore, the use of toothed material boxes will greatly reduce the production capacity of the entire trimming and forming system. Due to the above factors, manufacturers of automatic trimming and forming systems need to find new feeding methods
