[0046] A product placement fixture 400, including a placement plate 401;

[0047] The visual camera device 500 includes a mounting bracket 503;

[0048] The wire pulling device 300 also includes a lifting cylinder 304 fixed to one side of the linear module 305, a rotating cylinder 303 fixedly connected to one side of the lifting cylinder 304, and a clamping cylinder 302 fixed to one side of the rotating cylinder 303;

[0049] The six-axis manipulator 200 cooperates with the linear module 305 to drive and transport the product, and can perform automatic wire pulling operations. The six-axis manipulator 200 is used to carry the wire pulling movement, and the accuracy is about ±0.03 to ensure the reliability of repeated positioning;

[0050] The wire pulling station is composed of a clamping mechanism consisting of a linear module 305 and a clamping claw cylinder 302, which simulates the manual material pulling and wire pulling posture for operation; the wire pulling claw adopts a pressure sensor 306 for sensing, which significantly ensures the safety of the product plug 301 when pulling the wire and improves the repeatability of the action;

[0051] The linear module 305 is located at the front end of the top surface of the upper horizontal plate 103 and in front of the connection between the six-axis manipulator 200 and the upper horizontal plate 103; the lifting cylinder 304 is located on the left side of the linear module 305, the rotating cylinder 303 is located on the left side of the lifting cylinder 304, and the gripper cylinder 302 is located on the left side of the rotating cylinder 303;

[0053] The pressure sensor 306 is located on the left side of the rotating cylinder 303;

[0054] The product placement fixture 400 also includes a placement platform 404 fixed to the top surface of the placement plate 401 and two sets of plug placement fixtures 403 fixed to one end between the placement platforms 404;

[0055] There are two groups of placement platforms 404, each group has two, and product 2 402 is placed on the top surface of the placement platform 404;

[0056] The placement plate 401 is located at one end of the wire pulling device 300;

[0057] The plug placement fixture 403 has a strong magnetic adsorption effect, which can better position and protect the product, reduce the loss of the plug and the time-consuming replacement of personnel. The placement platform 404 is used to place the schematic product 2 402, and the placement plate 401 can be connected and placed with other objects; the placement plate 401 is located at the front end of the wire pulling device 300;

[0058] The visual camera device 500 also includes a plane light source 502 fixed to the bottom end of the mounting bracket 503, and a CCD camera 501 fixed to one side of the bottom end of the mounting bracket 503;

[0059] The plane light source 502 is located above the placement platform 404, a connection hole 504 is provided on the upper surface of the plane light source 502, and a CCD camera 501 is located above the connection hole 504;

[0060] There are two planar light sources 502 and two CCD cameras 501;

[0061] The CCD camera 501 can take a picture of the product 2 402 on the fixture. After taking the picture, the CCD camera 501 uploads the product positioning information to the six-axis manipulator 200 through signal transmission. The plane light source 502 is used to provide the CCD camera 501 with a light source for taking pictures. The mounting bracket 503 is mounted with other objects so that the CCD camera 501 is installed at a fixed height, which is convenient for taking pictures of the products below. The CCD camera is located on the front below the mounting bracket 503, and the average cycle time of a single product is ≤7s.

[0062] The main assembly 100 further includes support frames 102 fixed to both sides of the bottom surface of the upper horizontal plate 103, a bottom plate 101 fixed between the bottom ends of the support frames 102, and a motor 104 fixed to the top surface of the bottom plate 101;

[0064] Working principle:

[0065] The upstream product is placed on the product placement fixture 400 and transported to the automatic wire pulling station through the assembly line. Then, the CCD camera 501 takes a photo to locate the product, and then uploads the product location information to the robot arm 201 through signal transmission.

[0066] The robot arm 201 moves to the top of the product 1 203, grabs the product 1 203 through the suction cup 202, and then the robot arm 201 moves again to a fixed position to pull out the wire;

[0067] The robot arm 201 picks up the material and moves it to a fixed position, and then the lifting cylinder 304 lifts it to the designated position for the clamping cylinder 302 to clamp the product plug 301. The pressure sensor 306 knows that the clamping is successful through the feedback pressure value, and the linear module 305 moves to pull the wire. After the wire pulling is successful, the rotary cylinder 303 rotates 180°, and then the linear module 305 moves to the plug placement fixture 403 to place the product plug 301. The product plug 301 is adsorbed on the plug placement fixture 403. Then, after the wire pulling is completed, the six-axis robot arm 200 scans the product code for traceability, and finally places it in the downstream assembly line to enter the next work station. At the same time, all product data needs to be stored and traced. The system can be connected to the customer's existing MES system, and the customer provides the MES interface definition;

[0068] The above steps improve your functionality.
