The working principle of the utility model is as follows:

before use, referring to fig. 6-7, firstly, the feeding block is installed in the vibrating tray and fixed on the vibrating tray through the feeding block installation hole 12 (the reference sign a in fig. 6 indicates the installation position of the feeding block, and the reference sign B in fig. 7 indicates the feeding block), and at this time, a channel for screening chips is formed between the left side wall of the boss 13 and the vibrating tray; then, the air pipe is respectively connected with the openings of the triggering air blowing connecting hole 17 and the main permanent air blowing connecting hole 18, the opening of the auxiliary permanent air blowing connecting hole 19 is blocked by a plug to keep sealing, and at the moment, an air electromagnetic valve is installed on a pipeline connected with the triggering air blowing connecting hole 17 and is connected with the control assembly; and then fixing the bracket provided with the optical fiber probe on the feeding block through a bracket connecting hole 11, wherein the optical fiber probe is positioned right above a channel formed between the left side wall of the boss 13 and the vibration disc, and the optical fiber probe is also connected with the control assembly.

When the feeding block is installed, the channel distance between the left side wall of the boss 13 and the vibration disc needs to be adjusted according to the size of the short edge of the tested packaged chip, firstly, the lower edge of the short edge of the chip is tightly attached to the vibration disc, the feeding block is moved, and after the distance between the upper edge of the short edge of the chip and the left side wall of the boss 13 is 0.05mm, the feeding block is locked and fixed through a locking screw; in order to adjust the accuracy of the channel spacing, the following two methods can be adopted: 1) Aligning the magnifier at the axial center line of the adjusting slot 15, and adjusting the upper edge of the chip to be close to the axial center line without exceeding the axial center line; 2) A0.05 mm thick filler piece is inserted into the adjustment groove 15 and is pressed between the upper edge of the chip and the left side wall of the boss 13.

When the chip feeding device works, a chip is placed in the material vibrating disc, the long-edge air blowing holes 14 continuously blow air outwards, the chip enters a channel formed between the left side wall of the boss 13 and the material vibrating disc under the conveying of the material vibrating disc, when the chip enters from the long edge, the long edge of the chip is larger than the distance between the channels, the chip cannot completely enter the channel, one edge of the chip is in contact with one side of the material vibrating disc in the channel, the other edge of the chip slides onto the boss 13 along the oblique angle on the boss 13, and the air blown out of the long-edge air blowing holes 14 arranged on the boss 13 blows towards the long edge of the chip on the boss 13, so that the chip is blown off from the upper part of the channel, and the chip enters the material vibrating disc again; when the chip enters the channel from the short side, the optical fiber probe arranged right above the channel detects the front side and the back side of the chip, when the chip is on the front side, the chip is continuously conveyed forwards, when the chip is on the back side, the control assembly controls the air electromagnetic valve to be opened, air is supplied into the trigger air blowing connecting hole 17, so that the trigger air blowing hole 16 blows air outwards, the chip is blown out from the channel, and the chip enters the vibration feeding tray again; so that the chips passing through the feed block are all conveyed to the next packaging test feed inlet by the short side and the front side.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
