[0040] Please refer to Figure 2 In the present embodiment, the feeding device 2 comprises four first positioning columns 16, and a first positioning plate 17 is extended on one side of each first positioning column 16. The four first positioning columns 16 position the two opposite sides of the material tray 6 of the stacked layer to be processed, and the four first positioning plates 17 position the other two opposite sides of the material tray 6 of the stacked layer to be processed, so as to stably and regularly limit the multiple stacked material trays.

[0041] Please refer to Figure 1 , Figure 3 ,and Figure 4 Furthermore, the feeding device 2 also includes a first top plate assembly 3 and a first carrying plate assembly 18. The first top plate assembly 3 is lifted and lowered below the processed stacked material tray 6.

[0042] When the feeding device 2 is working, the first top plate assembly 3 lifts up the tray of the stacked layer to be processed, the first carrying plate assembly 18 releases the support of the tray of the stacked layer to be processed, and then the tray of the stacked layer to be processed descends with the first top plate assembly 3, and the bottom tray is placed on the belt conveyor 1, and then the first carrying plate plate 181 of the first carrying plate assembly 18 supports the other trays above the bottom tray, and the bottom tray and the tray above it will be separated by a certain distance, and the belt conveyor 1 only transports the bottom tray, and this step is repeated to transport the trays of the stacked layer to be processed one by one for dispensing.

The sensor 43 is used to sense whether the telescopic heights of the multiple telescopic columns 42 after contacting the product are consistent. Each sensor 43 can sense multiple telescopic columns 42 in the same row. When the sensor 43 senses that the heights of the multiple telescopic columns 42 are different, it means that the multiple products in the tray 6 are not placed consistently and there are different heights.

[0046] Please refer to Figure 1 and Figure 6 In this embodiment, the tray conveying mechanism 7 stably clamps the tray 6 on the belt conveyor 1 and conveys it to the glue dispensing position, avoiding relative sliding between the tray 6 and the belt conveyor 1, so that subsequent glue dispensing is more accurate.

The positioning rod 93 is connected to the bottom of the end of the movable plate 92 away from the positioning drive unit 91. The tray 6 is provided with a positioning hole for positioning and connecting with the positioning rod 93. Figure 8 In the viewing direction, the positioning drive unit 91 drives the movable plate 92 to slide down, so that the positioning rod 93 is inserted into the positioning hole of the material tray 6, thereby positioning and fixing the material tray so that the dispensing mechanism 10 can perform precise dispensing.

[0051] Please refer to Figure 1 , Fig. 9 and Fig.10 In addition, the positioning device also includes a product positioning component 8, which includes a lifting frame 81 and a third positioning plate 82.
