[0006] Furthermore, the filling assembly includes a hopper, a through-beam sensor, and a filling valve for controlling the discharge of material from the hopper. The hopper is fixed above the first support column, and the filling valve is located at the outlet of the hopper. The through-beam sensor is located on the inner side of the first support column, and the position of the through-beam sensor is the same as the height of the bottle body on the first conveyor belt.

[0007] Furthermore, an elongated groove is formed on the inner side of the first support column, and a lead screw is installed in the elongated groove. A first motor is fixed to the top of the first support column, and the top of the lead screw is fixedly connected to the output end of the first motor. The other end of the lead screw is rotatably fixed to the bottom of the elongated groove through a bearing. A bushing is fitted on the lead screw, and the bushing is fixedly connected to the hopper through a support plate.

[0008] Furthermore, the cover assembly includes a support frame, on which a linear slide is fixed. A first fixing plate is fixed on the slider of the slide. A second fixing plate is fixed to the right end of the first fixing plate. A first telescopic cylinder is fixed to the second fixing plate. A rotary cylinder is fixed to the output end of the first telescopic cylinder. A third fixing plate is fixed to the output end of the rotary cylinder. A pneumatic suction cup is provided on the third fixing plate.

[0009] Furthermore, the pneumatic suction cup component includes a suction cup, a solenoid valve, a second telescopic cylinder, a fourth fixing plate, an upper pipe, and a lower pipe. The suction cup is fixed below the third fixing plate and is positioned opposite the rotation axis of the rotary cylinder. The lower pipe is fixed above the third fixing plate and located on the side of the rotary cylinder. The fourth fixing plate is fixed to the front side of the first fixing plate. The second telescopic cylinder is fixed on the fourth fixing plate. The output end of the second telescopic cylinder is fixed to the upper pipe and is positioned opposite the lower pipe. The solenoid valve is disposed on the lower pipe.

[0010] Furthermore, the support frame includes a base plate, a top plate, and a fixing rod. The top plate is fixed to the top of the fixing rod, the base plate is fixed to the bottom of the fixing rod, a bearing plate is fixed to the middle of the fixing rod, and the linear slide is fixed to the bearing plate.

[0011] Furthermore, the group conveying assembly includes a limiting ring block, a fourth conveyor belt, a fifth conveyor belt, and a turntable. The limiting ring block is fixed to the outside of the turntable by a column. The limiting ring block has an inlet on one side of the second conveyor belt, and a first outlet and a second outlet are provided on the limiting ring block. The fourth conveyor belt is provided at the first outlet, and the fifth conveyor belt is provided at the second outlet.

[0012] Furthermore, the turntable component includes a second motor and a reducer. The second motor is located on top of the base and fixed to the square plate. The output end of the second motor is fixed with a first output shaft. One end of the reducer is fixed with a second output shaft.

The turntable has multiple arc-shaped openings for carrying the cosmetics.

[0013] Furthermore, the method of use includes the following steps:

[0014] Step S1: Place empty cosmetic bottles evenly on the first conveyor belt. The empty bottles are then conveyed to the bottom of the filling assembly via the first conveyor belt. When the through-beam sensor on the first support column detects a cosmetic bottle, the filling assembly performs quantitative filling on the empty bottle.

[0015] Step S2: After filling, the bottle is conveyed to the placement slot on the second conveyor belt and then to the bottom of the capping assembly.

[0016] Step S3: The suction cup in the capping assembly picks up the bottle cap on the third conveyor belt and transports it to the top of the bottle body held by negative pressure for capping. The capped cosmetic is then transported to the end of the second transmission belt via the second conveyor belt.

[0017] Step S4: The camera at the end of the second conveyor belt identifies the barcode on the cosmetics and controls the second motor in the group conveying component to rotate forward or backward based on the identified barcode, so that the cosmetics are conveyed to different exits for group conveying.

[0018] The beneficial effects of this invention are as follows: This invention integrates the filling and capping processes of cosmetics by using a first conveyor belt and a second transmission belt. The first conveyor belt transports empty bottles to the bottom of the filling assembly, where the filling assembly quantitatively fills the empty bottles. After filling, the bottles are conveyed to a placement slot on the second conveyor belt. When the bottles are conveyed to the bottom of a suction cup, the micropores at the bottom of the placement slot generate negative pressure to hold the filled bottles in place. The negative pressure ensures that the bottles will not rotate during the capping process. At the same time, the negative pressure suction removes the caps from the suction cups. The suction cups first retrieve the caps from the third conveyor belt and then convey them to the top of the filled bottles held by negative pressure for capping. The capped cosmetics are then conveyed to the end of the second transmission belt via the second conveyor belt. A camera at the end of the second conveyor belt can identify the barcodes on the cosmetics, and the products are then grouped and conveyed to the exit based on the identified barcodes. This invention can integrate the filling and capping processes into one, enabling automated production, and can also identify different product codes and send them to different product channels.
