[0005] The material handling unit includes a first drive assembly mounted on the frame body and a first mounting base plate mounted on the output end of the first drive assembly. The first drive assembly can drive the first mounting base plate to move up / down. A second drive assembly is disposed on the first mounting base plate. A second mounting plate is connected to the output end of the second drive assembly. At least two sets of clamping assemblies for clamping products are disposed on the second mounting plate. The second drive assembly can drive the second mounting plate to rotate circumferentially.
[0006] The turntable includes a third drive assembly mounted on the frame body and a turntable mounted on the output end of the third drive assembly. The turntable is provided with several sets of fixture assemblies, which are evenly distributed around the circumference of the turntable along the center. The fixture assemblies are used to place products.
[0007] Furthermore, the feeding unit includes a vibratory plate mounted on the frame body and a first three-coordinate drive arm. The first three-coordinate drive arm is provided with a first picking head for picking up O-rings. The first three-coordinate drive arm can drive the first picking head to pick up O-rings from the vibratory plate and place them into the fixture assembly.
[0008] Furthermore, the pressing part includes a screw feeder and a second three-axis drive arm mounted on the frame body. The second three-axis drive arm is provided with a second picking head that picks up screws. The second three-axis drive arm can drive the second picking head to pick up screws from the screw feeder, place them on the product, and press them down to engage with the O-ring.
[0009] Furthermore, the clamping assembly includes a fourth drive assembly mounted on the second mounting plate and a gripper mounted on the output end of the fourth drive assembly, the fourth drive assembly being able to drive the gripper to open / clamp.
[0010] Furthermore, the fixture assembly is provided with several receiving slots for placing O-rings, and the fixture assembly is provided with a ventilation pipe connected to the several receiving slots. The ventilation pipe is connected to a gas source through several air nozzles, and the gas can adsorb / release the O-rings in the receiving slots through the ventilation pipe.
[0011] Furthermore, the third drive component is a motor.
[0012] The beneficial effects of this utility model are:
[0013] 1. This utility model divides the turntable into 6 stations. Stations 1 and 2 are used to place O-rings on the fixture assembly. Then, a worker places the radiator at station 3. Stations 4 and 5 place screws and fasteners. Station 6 removes the radiator. This solves the problem of fastening the radiator screws and O-rings. The entire process uses only one worker and two sets of stations to place screws and O-rings at the same time, resulting in high production efficiency.
[0014] 2. The container of this utility model is connected to a high-pressure air source. After the O-ring is placed in, the air source can blow or suck air to fix and loosen the O-ring in the container, preventing the O-ring from falling off and improving the stability of equipment operation.
