[0056] Furthermore, the demoulding ejector 64 includes a demoulding ejector pin 641, which corresponds to the hole position on the product 300, so that the product 300 can be positioned and the product 300 can be ejected from the product installation position 51 of the positioning panel 50. Of course, the demoulding ejector 64 also includes a demoulding ejector block 642, and the demoulding ejector pin 641 corresponds to the main body of the product 300. Through the cooperation of the demoulding ejector pin 641 and the demoulding ejector block 642, the product 300 can be ejected from the product installation position 51 of the positioning panel 50 more easily to avoid damage to the product 300 during the demoulding process.

[0057] Furthermore, the positioning panel 50 is provided with a plurality of positioning pins 52, and each product installation position 51 is provided with a corresponding positioning pin 52, and the positioning pin 52 corresponds to the hole position on the product 300, so that the product 300 can be better positioned. Figure 7As shown, a suction hole 211 and a limiting hole 212 are provided at the bottom of the suction head 21. The suction head 21 sucks the product 300 through the suction hole 211. The limiting hole 212 corresponds to the positioning pin 52 on the positioning panel 50, thereby improving the accuracy of placing the product 300 on the product installation position 51 of the positioning panel 50.

[0058] In this embodiment, Figure 3 and Figure 4 As shown, a positioning hole 122 is provided on the side of the bottom frame 12 facing the positioning panel 50, and a positioning column 53 matching the positioning hole 122 is provided on the side of the positioning panel 50 facing the bottom frame 12, thereby ensuring accurate alignment of the suction device 100 and the positioning fixture 200 when they cooperate, so as to improve the accuracy of placing the product 300 on the product installation position 51 of the positioning panel 50.

[0059] The working process of the automation equipment in this application includes: The fixture driver 321 fixed on the top plate 11 pushes the transmission rod 325 to drive the ejector mounting plate 322 to move downward along the guide column 13, and inserts the fixture ejector 324 into the middle of the wedge-shaped opening 303 of the calibration fixture 31, so that the first calibration block 311 and the second calibration block 312 of the calibration fixture 31 move to both sides, so that the calibration opening 301 is opened to prevent the suction head 21 from sucking the first component 310 of the product 300 ( Fig.12 ) touches the calibration fixture 31 when retracting.

[0060] The suction head driver 222 pushes the driving connecting member 2231 to move downward, pushes the elastic member 2235 to move downward, and the suction head mounting member 2232 is connected to the slide rail 221a of the fixed plate 221, and moves downward with the suction head 21 at the bottom under the action of the elastic member 2235. The suction heads 21 on one side of the fixed plate 221 are all extended out of the calibration port 301 of the calibration fixture 31, and simultaneously absorb the six first components 310, and then retract together to the calibration port 301 under the action of the suction head driver 222. The suction head driver 222 on the other side of the fixed plate 221 also drives the suction head 21 to move downward and absorb the six first components 310, and then retract to the calibration port 301 of the calibration fixture 31.

[0061] After the suction heads 21 on both sides of the fixed plate 221 have all sucked the first component 310 and retracted to the calibration port 301 of the calibration fixture 31, the fixture driver 321 drives the ejector mounting plate 322 to retract upward along the guide column 13 through the transmission rod 325, and drives the fixture ejector 324 to move upward. Under the action of the fixture reset member 323, the first calibration block 311 and the second calibration block 312 move along the guide rod 121 to the middle of the calibration port 301 and shrink the calibration port 301. The first component 310 of the product 300 is automatically calibrated under the clamping of the first calibration block 311 and the second calibration block 312 on both sides. The size of the opening and shrinking of the calibration port 301 is limited by the limit pin 121a on the guide rod 121 and the waist-shaped hole 302 on the first calibration block 311 and the second calibration block 312. Then the fixture driver 321 is pushed downward so that the fixture ejector pin 324 is inserted into the middle of the wedge-shaped opening 303 of the calibration fixture 31 again, so that the first calibration block 311 and the second calibration block 312 of the calibration fixture 31 are moved to both sides and opened to avoid the first component 310 of the product 300 and avoid affecting the suction head 21 from putting down the first component 310.

[0062] The suction device 100 sucking the first component 310 is driven by the four-axis robot arm on the automation equipment and moves to the positioning fixture 200 for positioning the product. The two positioning holes 122 on the bottom frame 12 match and assemble with the two positioning posts 53 on the positioning fixture 200, so that the bottom frame 12 and the positioning panel 50 are flat. The suction head driver 222 pushes the suction head 21 downward, and the limiting hole 212 on the suction head 21 matches with the positioning pin 52 on the positioning panel 50, and the first component 310 of the product 300 is installed into the product installation position 51 on the positioning panel 50, so that the hole position on the first component 310 is aligned with the positioning pin 52 and is sleeved on the positioning pin 52.

[0063] Before the first component 310 is placed on the product installation position 51 on the positioning panel 50, the second component 320 of the product 300 has been installed on the product installation position 51 of the positioning panel 50. After the first component 310 and the second component 320 are positioned on the positioning panel 50, the first component 310 and the second component 320 are welded together through subsequent processing to form the product 300.

[0064] Then, another suction device 100 moves to the positioning fixture 200, and the two positioning holes 122 on the bottom frame 12 match and assemble with the two positioning posts 53 on the positioning fixture 200, so that the bottom frame 12 and the positioning panel 50 are flat. The suction head driver 222 pushes the suction head 21 downward, and the limiting hole 212 on the suction head 21 matches with the positioning pin 52 on the positioning panel 50. The suction head 21 sticks to the product 12 and sucks the entire product 300, ensuring that the product 300 will not move when it moves away from the positioning pin 52.

[0065] The demoulding driver 61 pushes the plurality of driving rods 62 backwards through the connecting plate 65. When the driving rods 62 move backwards, the connecting rods 63 move upwards through the driving inclined surfaces 621 on the driving rods 62. The connecting rods 63 drive the demoulding ejector 64 to move upwards during the upward movement. The demoulding ejector 64 moves vertically upwards through the through holes 502 on the positioning panel 50. In this process, the product 300 is vertically pushed out from the positioning pins 52 of the product installation position 51. At the same time, during the upward movement of the product 300, the suction head 21 and the suction head installation part 2232 are pushed upwards as a whole, because an elastic part 2235 is provided between the suction head installation part 2232 and the protrusion 2233 to play a limiting and buffering role.

[0066] When the product 300 is removed, the output shaft of the demolding driver 61 retracts, and the first demolding reset member 661 drives the connecting rod 63 to move downward and reset the demolding ejector 64, while the second demolding reset member 662 allows the driving rod 62 to slide and reset along the axial direction of the driving rod 62.

[0067] The same suction device 100 can be used to suck the first component 310 and the entire product 300. Two suction devices 100 can also be used to suck the first component 310 and the entire product 300 respectively. The two suction devices 100 are identical in structure, except that the spacing between the suction heads 21 is different. The position of the suction head 21 for sucking the first component 310 on the positioning panel 50 corresponds to the first component 310, and the position of the suction head 21 for sucking the entire product 300 on the positioning panel 50 corresponds to the second component 320, so as to avoid deformation of the product 300 due to uneven force when sucking the entire product 300.

[0068] The present application can calibrate the position of the product 300 when sucking the product 300 through the suction device 100, and the positioning fixture 200 can push and detach the product 300 from the positioning fixture 200, thereby improving the efficiency and yield of product suction, positioning and detachment.
