Description

Unloader on charging tray

Technical Field

The utility model relates to the field of automatic feeding and discharging of electronic materials, in particular to a feeding and discharging device for a material tray.

Background

Referring to fig. 1, the electronic material is automatically loaded and unloaded without separating the tray. The charging tray 9 is used for containing electronic materials so as to facilitate the automatic transportation of the electronic materials. The upper surface of the general tray 9 is provided with pits 91 which are distributed in an array and used for placing electronic materials. The bottom of one pair of sides of the tray 9 is provided with a plurality of bayonets 92. Preferably, two bayonets 92 are provided on one side. An upper fence 93 which protrudes upwards is arranged around the tray 9, and a lower fence 94 which protrudes downwards is arranged around the tray 9. When the trays 9 are stacked, the lower rail 94 of the upper tray 9 can be sleeved on the upper rail 93 of the lower tray 9. Thus, the bottom of the upper tray 9 can be pressed on the concave pit 91 to prevent the electronic materials from being separated from the concave pit 91. However, since electronic materials, especially chip materials, are smaller and lighter, in the transportation and transfer processes of the existing charging tray 9, no sleeve is in place up and down when the charging tray 9 is stacked, so that the electronic materials are easy to separate from the pits 91 in the moving process of the charging tray, and the electronic materials in the charging tray are dislocated and skip. In addition, electronic materials such as chip materials are light and small, and in the transportation and transfer processes of the material tray 9, due to the fact that the lifting and moving processes are not stable enough, the electronic materials are easy to separate from the pits 91, so that the electronic materials in the material tray are staggered/jumped, and the material cannot be loaded and unloaded. And the chips in the tray are put well again, so that great manpower and time are consumed, and the feeding and discharging efficiency of the chips is seriously influenced.

In addition, the two bins of the existing charging tray charging and discharging device cannot realize the function exchange of the charging bin and the recovery bin to form different charging and discharging modes, and further cannot be adapted to different devices; the tray transfer efficiency between the tray loading and unloading device mechanisms is not high, and further optimization and improvement are needed.

The height of the buckle 6110 of the receiving plate assembly 611 is matched with the height of the bayonet at the bottom of the material tray on the moving plate of the second translation mechanism 7, so that when the material tray on the moving plate of the second translation mechanism 7 is horizontally moved into the receiving plate structure, the buckle 6110 of the receiving plate structure can move oppositely, namely the buckle is closed, so that the bottom of the material tray on the moving plate of the second translation mechanism 7 is supported, or when the moving plate of the second translation mechanism 7 is horizontally moved into the receiving plate structure, the buckle 6110 can move oppositely, namely the buckle is opened, so that the material tray is released to the moving plate of the second translation mechanism 7, and the material tray is transferred between the receiving plate structures of the second translation mechanism 7 and the second lifting transfer mechanism 6.

Similarly, a mutual avoiding structure is arranged between the lifting plate 607 of the second lifting transfer mechanism 6 and the moving plate of the first transfer mechanism 5, so that the lifting plate 607 of the second lifting transfer mechanism 6 can upwards penetrate through the moving plate of the first transfer mechanism 5 to lift up a material tray of the moving plate of the first transfer mechanism 5 during lifting; or when the lifting plate 607 of the second lifting transfer mechanism 6 descends, the material tray can downwards pass through the moving plate of the first transfer mechanism 5 to be released to the moving plate of the first transfer mechanism 5; or the moving plate of the first translation mechanism 5 and the lifting plate 607 of the second lifting and transferring mechanism 6 can be at the same horizontal height at a certain moment to realize the smooth transfer of the material tray.

The second bin 4 further comprises a tray supporting plate 43, a supporting plate driving air cylinder 44 and an air cylinder fixing plate 42, the second bin 4 is located on the front side and the rear side of the material disc and is provided with the air cylinder fixing plate 42, the supporting plate driving air cylinder 44 is fixedly installed on the air cylinder fixing plate 42, and the tray supporting plate 43 is connected with the supporting plate driving air cylinder 44. The tray supporting plates 43 on the front side and the rear side of the material tray move oppositely under the driving of the supporting plate driving cylinders 44 to support the material tray, or move oppositely under the driving of the supporting plate driving cylinders 44 to release the material tray to the jacking plate 307 of the first lifting transfer mechanism 3, so that the material tray is transferred between the first lifting transfer mechanism 3 and the second storage bin 4.

Preferably, during the process that the first lifting and transferring mechanism 3 lifts upwards to transfer the material tray to the second storage bin 4, the supporting plate driving cylinder 44 of the second storage bin 4 is opened, that is, the tray supporting plate 43 extends towards the inside of the guiding frame 41 of the second storage bin 4, and the material tray on the lifting plate 307 of the first lifting and transferring mechanism 3 is not allowed to enter; until the jacking plate 307 jacks the material tray for a certain distance, the material tray and the material tray at the lowest layer of the second storage bin 4 are mutually and uniformly stacked, so that the lower fence 94 of the upper material tray 9 can be uniformly clamped and sleeved on the upper fence 93 of the lower material tray 9. Thus, the bottom of the upper tray 9 can be well pressed on the concave pit 91, and the electronic materials are prevented from being separated from the concave pit 91. After the gap between the tray and the lowest tray in the second silo 4 is eliminated, the tray driving cylinder 44 is turned off again, that is, the tray supporting plate 43 retracts to allow the tray on the lifting plate 307 of the first lifting and transferring mechanism 3 to further lift and enter the second silo 4. When the lifting plate 307 of the first lifting and transferring mechanism 3 is lifted to the highest position, the supporting plate driving cylinder 44 is opened, that is, the tray supporting plate 43 extends into the guiding frame 41 of the second storage bin 4 to support the tray on the lifting plate 307, and the tray is transferred to the second storage bin 4.
