Automatic screw machine

Abstract

The invention provides an automatic screw machine, which includes a base plate, a screw locking device arranged on the base plate, a conveying mechanism and a vacuum adsorption mechanism arranged behind the screw locking device, and the conveying mechanism includes a A tube frame, a group of chip tubes are stacked in the tube frame, the chip tube at the bottom is a working tube, and an elastic pusher passes through it, and a retention block is provided at the front end of the chip tube, and the The retention block includes a receiving part for adapting chips and a baffle at the front end, the height from the receiving part to the substrate is equal to the height from the chips in the chip tube to the substrate. The beneficial effects of the present invention are mainly reflected in that the receiving part of the indwelling block provided by the present invention can always accommodate a chip, ensuring that the chip will not have any displacement when the elastic push piece is retracted, ensuring the suction position of the vacuum adsorption device, and improving production. pass rate.

Description

technical field [0001] The invention relates to a mechanical automation device, in particular to an automatic screw machine. Background technique [0002] At present, many electrical products are equipped with heat sinks and chips fixed on the heat sinks. However, the traditional assembly of heat sinks and chips requires operators to manually remove the heat sinks and chips, and position the chips on the heat sink. Then lock the screws to assemble. [0003] The Chinese patent CN201420747928.1 applied by the applicant discloses a screw locking mechanism, but it does not disclose the specific delivery mechanism of the chip. In the actual production process, chips are generally transported using chip tubes, which are pushed by an elastic pusher. However, due to the elastic effect of the elastic pusher, when only one chip is left in a chip tube, the elastic pusher returns The chip will also have a small backward displacement when the time is shortened, so that there will be a ...

[0003] The Chinese patent CN201420747928.1 applied by the applicant discloses a screw locking mechanism, but it does not disclose the specific delivery mechanism of the chip

In the actual production process, chips are generally transported using chip tubes, which are pushed by an elastic pusher. However, due to the elastic effect of the elastic pusher, when only one chip is left in a chip tube, the elastic pusher returns The chip will also have a small backward displacement when the time is shortened. In this way, when using the vacuum adsorption device for transfer, there will be problems that are not in place, which will have a great impact on the subsequent automatic screw locking, resulting in a large number of defective products.
