Technical Field

The invention relates to the field of automatic feeding, in particular to an automatic feeding and discharging device for a material tray and a feeding method of the automatic feeding and discharging device.

Background

In many automated production, inspection and manufacturing devices (e.g., chemical inspection and automated processing), a tray is used for feeding, and the tray can carry parts to be inspected or processed, or can carry samples to be inspected or processed. During feeding, usually, an operator manually places the tray at a feeding position of the device, so that the device can perform subsequent operations such as detection, processing, uncovering and the like on test tubes or parts and the like stored on the tray. However, in the manual feeding scheme, only one feeding tray can be fed each time, and then an operator needs to take the feeding tray away manually during feeding, so that the operator needs to frequently load and unload the feeding tray, the efficiency is low, and meanwhile, the personnel cost is high.

The above-mentioned problem that exists to the artifical charging tray about, some automatic feed's scheme has appeared among the prior art, like the tray automatic feed mechanism that prior art 201822001936.2 disclosed, let operating personnel can once only put a plurality of charging trays at the material loading station of equipment, later equipment can take these charging trays one by one or once take away in order to carry out follow-up operation, carry these charging trays to unloading station after finishing again, through the quantity that increases the material loading station, just can effectively reduce the number of times of artifical feed, improve overall efficiency. However, the conventional feeding scheme usually needs to realize the grabbing and transferring of the tray based on mechanisms such as a mechanical arm and the like, and the cost and complexity are high, which is not beneficial to maintenance. In addition, in order to ensure that all the trays subjected to one-time feeding can be successfully and automatically fed without the intervention of an operator, the number of the feeding stations and the number of the feeding stations are required to be correspondingly the same, so that the feeding stations of the trays can accommodate the maximum number of the trays subjected to one-time feeding, for example, if there are 2 feeding stations, the number of the feeding stations is also 2 assuming that the number of the trays accommodated in each station is the same. However, the loading station and the unloading station occupy space, so that the whole volume of the equipment is increased along with the increase of the number of the stations, more space is occupied, and the cost of the equipment is increased by changing the direction.
