[0048] Regarding the detachable connection between the material taking module 400 and the first manipulator 300,

[0049] At least two quick-change male heads 601 and at least two first positioning pins are installed on the first robot 300 .

[0050] The material picking module 400 is provided with a quick-change female head 502 and a first positioning hole, the quick-change male head 601 is plugged into the quick-change female head 502, and the first positioning pin is plugged into the first positioning hole. The first manipulator 300 is detachably connected to the material picking module 400 through the quick-change male head 601, the quick-change female head 502 and the first positioning pin.

[0051] Regarding the detachable connection between the positioning module 500 and the second manipulator 600,

[0052] At least two quick-change male heads 601 and at least two third positioning pins are installed on the second robot 600 .

[0053] The positioning module 500 is provided with a quick-change female head 502 and a second positioning hole 501, the quick-change male head 601 is plugged into the quick-change female head 502, and the third positioning pin is plugged into the second positioning hole 501. The second manipulator 600 is detachably connected to the positioning module 500 through the quick-change male head 601, the quick-change female head 502 and the third positioning pin.

[0054] The quick-change head and the positioning pins can be used to position the material taking module 400 or the positioning module 500 when the material taking module 400 or the positioning module 500 is replaced.

[0055] In this embodiment, the second positioning hole 501 and the material discharge positioning hole can be the same positioning hole, so that when the material picking module 400 and the second manipulator 600 cooperate with the positioning module 500, they can be positioned by cooperating with the same positioning hole through their respective pins, thereby reducing the number of openings on the positioning module 500.

[0056] In a further embodiment, the automatic pin embedding device further includes: an optical fiber sensor 102 mounted on the platform frame 100 .

[0057] When the positioning module 500 is placed at a predetermined position on the platform frame 100 , the optical fiber sensor 102 is used to detect whether a copper needle is inserted into the positioning module 500 .

[0058] Regarding the quick-change male connector 601 and the quick-change female connector 502,

[0059] The quick-change male connector 601 includes a main body 5011 connected to the robot, a pop-up piece 5012 installed on the side wall of the main body 5011, and a quick-change air duct 5013 arranged in the main body 5011.

The ball partially passes through the side wall of the main body 5011 and extends into the annular groove 5021.

[0062] When air is ventilated in the quick-change air passage 5013 , the force acting on one end of the ball against the side wall of the main body 5011 increases, so that the connection between the quick-change male connector 601 and the quick-change female connector 502 remains stable.

[0063] Working principle: first, the bags of copper needles are poured into the vibration plate 201 of the discharging module 200, the vibration plate 201 of the discharging module 200 vibrates and discharges the copper needles to the predetermined position, and then the turning mechanism 202 arranges the copper needles that have reached the predetermined position vertically.

[0064] Then the first robot 300 inserts the copper needle in the discharging module 200 into the positioning module 500 placed on the platform frame 100 through the picking module 400. When the picking module 400 leaves above the positioning module 500, the optical fiber sensor 102 detects whether the copper needle is inserted into the positioning module 500.

[0065] Then the second robot 600 carries the positioning module 500 with the copper needle inserted into it to the injection molding machine 700 for product injection molding.

[0066] When product parameters change, such as the size of the copper needle, the original material picking module 400 is removed from the first manipulator 300, and the original positioning module 500 is removed from the platform frame 100, and then the corresponding material picking module 400 is installed on the first manipulator 300, and the corresponding positioning module 500 is placed on the platform frame 100.

[0067] By detachably connecting the material picking module 400 with the first manipulator 300 and separating the positioning module 500 from the injection molding machine 700, the copper needle is inserted into the positioning module 500 using the first manipulator 300 and the material picking module 400, and then the positioning module 500 is placed into the injection molding machine 700 through the second manipulator 600. The corresponding material picking module 400 and positioning module 500 can be replaced when product parameters change, so that one device can correspond to multiple products. Compared with replacing the entire equipment, the replacement cost is greatly reduced, and compared with manual pin insertion, the product consistency is greatly improved, and the production cost and work risk are greatly reduced.

[0068] In the second embodiment, based on the first embodiment, the detachable connection mode between the material taking module 400 and the first manipulator 300 is changed.
