Description

Technical Field

The first product (20, 30) continues to move forward to the end. When the first proximity switch 46 senses the product (20, 30), the spider hand robot 8 grabs the product (20, 30), the sensing signal of the first proximity switch 46 disappears, and the second three-axis cylinders 41 on both sides retract, thereby completing the material distribution cycle.

[0107] Working principle of this utility model:

[0108] The PLC controls the feeding belt line 1 to transfer the aluminum shell 20 to the aluminum shell sorting mechanism 3. After the aluminum shell sorting mechanism 3 divides the batches of aluminum shells 20 into a row of aluminum shells 20 with uniform spacing, the PLC takes a picture of the mouth of the aluminum shell 20 through the visual module 5 to obtain positioning data, and the feeding belt line 1 transfers the aluminum shell 20 to the assembly area.

[0109] The PLC caches the jig 30 transmitted by the reflow belt line 2 onto the jig cache table 6 through the jig cache mechanism 7, and sucks the jig 30 through the spider hand robot 8 linked to the suction cup clamp 10, and assembles the jig 30 onto the aluminum shell 20 in the assembly area based on the positioning data of the vision module 5 and the position information calculated by the rotary encoder 47.

[0110] The assembled products (20, 30) are transferred to the end of the feeding belt line 1, and then the spider hand robot 8 links the gripper fixture 9 to grab the products (20, 30) to the next workstation.
