The Y-axis module 52 drives the Z-axis module 53 and the dispensing head 2 to move along the Y-axis direction. The Z-axis module 53 drives the dispensing head 2 to move along the Z-axis direction. The X-axis module 51, the Y-axis module 52 and the X-axis module 51 all include guide rails, motors, slides, etc. The motor drives the slide to move along the guide rails, wherein the two guide rails of the X-axis module 51 extend along the X-axis direction, the guide rail of the Y-axis module 52 extends along the Y-axis direction, and the guide rail of the Z-axis module 53 extends along the Z-axis direction.

[0034] In one embodiment of the present invention, referring to Figure 1 As shown, it also includes a first material receiving cup 61 and a second material receiving cup 6 fixedly arranged on the frame 1, and the driving mechanism 5 can drive the dispensing head 2 to move above the first material receiving cup 61 and the second material receiving cup 6, wherein the first material receiving cup 61 is placed on the weighing instrument 7, and the weighing instrument 7 is used to weigh the first material receiving cup 61 and the glue in the first material receiving cup 61, the first material receiving cup 61 is used to receive the glue to be weighed squeezed out by the dispensing head 2, and the second material receiving cup 6 is used to receive the solidified glue squeezed out by the dispensing head 2.

[0039] The working principle of the automatic dispensing device of the utility model is:

[0040] The material tray with the shell is transported to the dispensing station 3 by the conveying mechanism 8 and stops. Then the lifting platform 92 of the lifting mechanism 9 lifts the material tray and the shell to a predetermined height and then stops. If it is not necessary to weigh the amount of glue, the driving mechanism 5 directly drives the needle of the dispensing head 2 to the top of the shell to start dispensing. If it is necessary to weigh and detect the amount of glue, before dispensing, the driving mechanism 5 drives the dispensing head 2 to the top of the first receiving cup 61, and the dispensing head 2 drops the actual amount of glue into the first receiving cup 61. The weighing instrument 7 weighs the amount of glue and measures the amount of glue. The prescribed amount of glue is compared, and the glue dispensing head 2 adjusts the glue amount in time according to the comparison result. The driving mechanism 5 then drives the glue dispensing head 2 to move to the top of the shell for glue dispensing. If glue gathers around the glue outlet 21 of the needle, the driving mechanism 5 drives the needle to move to the cleaning mechanism 4 for cleaning. If the glue solidifies inside the needle, the driving mechanism 5 drives the needle to the top of the second material receiving cup 6 to squeeze the solidified glue into the second material receiving cup 6. When the shell is finished dispensing, the lifting platform 92 descends, the material tray is re-affected on the belt 82 and is transported to the next station.
