The driving motor 13 can control the rotating disk 10 to rotate horizontally on the top of the support seat 2 to adjust the position of the mold 11;

[0031] In this embodiment, a blocking frame 7 is provided in front of the six-axis robot 6, which provides protection for the six-axis robot 6, reduces damage to the six-axis robot 6 caused by external forces, and also reduces safety hazards caused by external personnel entering the work area;

[0032] like Figures 1 to 6 As shown, in this embodiment, an automatic detector 5 is installed at the left end of the inner side of the feeding rack 1, which is offset from the vibration plate 3 and the straight vibration track 4, and is used to detect nuts on the product;

[0033] A fixing frame 14 located in front of the straight vibration track 4 is locked and fixed to the front of the inner side of the feeding frame 1;

[0034] The mounting frame 8 is provided with a pick-up and placement mechanism 9 for picking up and placing products and nuts;

[0035] The fixing frame 14 is provided with a transfer assembly for adjusting the position of the nut;

[0036] The pick-and-place mechanism 9 includes a feeding cylinder 92 and a clamping cylinder 91 respectively fixed on the upper and lower end surfaces of the mounting frame 8. The clamping cylinder 91 is used to clamp the product. A pushing frame 93 is installed on the front piston rod of the feeding cylinder 92. The pushing frame 93 is used to push the nut into the mold 11. A vertical plate 94 connected to the top surface of the mounting frame 8 is arranged in front of the pushing frame 93. A placement hole 95 facing the pushing frame 93 is opened on the vertical plate 94. The inner side of the placement hole 95 is movably connected to the front end of the pushing frame 93.

[0037] In this embodiment, a limiting ball 96 is movably embedded in the placement hole 95 to clamp the nut, thereby preventing the nut from falling out of the placement hole 95;

[0038] In this embodiment, the limiting ball 96 is made of rubber, so that the limiting particle 96 can be elastically deformed by being squeezed by the nut;

[0039] In this embodiment, the automatic detector 5 is a photoelectric sensor, which utilizes the photoelectric effect. When a nut passes through a set position, it blocks or reflects light, thereby triggering the sensor to output a signal to determine whether there is a nut in the product.

[0040] like Figure 7 and Figure 8 As shown, in this embodiment, the transfer assembly includes a transfer cylinder 15 locked and fixed to the front end of the top of the fixing frame 14, a push cylinder 16 locked and fixed in the fixing frame 14, a nut guide sleeve 21 locked and fixed to the top of the rear end surface of the fixing frame 14, a transfer plate 17 fixed to the piston rod of the transfer cylinder 15 and slidably connected to the rear end of the top of the fixing frame 14, the transfer plate 17 can move horizontally along the top of the fixing frame 14 to drive the nut to adjust its position through the transfer plate 17, and a nut push rod 19 connected to the top piston rod of the push cylinder 16, which can be driven by the push cylinder 16 with a screw The female push rod 19 moves vertically to push the nut into the placement hole 95.

When the piston rod of the transfer cylinder 15 is in a retracted state, the positioning hole 20 is connected to the front end of the straight vibration track 4. When the piston rod of the transfer cylinder 15 is in a fully extended state, the nut push rod 19, the positioning hole 20 and the nut guide sleeve 21 are arranged vertically from bottom to top. At this time, the nut push rod 19 can vertically pass through the positioning hole 20 and the inner side of the nut guide sleeve 21. The nut push rod 19 passes through the positioning hole 20 to push the nut into the placement hole 95.

[0041] The inner diameter of the nut guide sleeve 21 is larger than the outer diameter of the nut push rod 19, so that the nut push rod 19 can quickly pass through the nut guide sleeve 21.

[0042] In this embodiment, a stop bar 18 is provided on the inner side of the transfer plate 17. When the piston rod of the transfer cylinder 15 is in a fully extended state, the stop bar 18 is attached to the front end surface of the straight vibration track 4, so that the stop bar 18 can block the next nut on the straight vibration track 4 to prevent the nut from falling.

[0043] When in use, the six-axis robot 6 controls the mounting frame 8 and the vertical plate 94 to move to above the nut guide sleeve 21, and controls the six-axis robot 6 so that the placement hole 95 faces the nut guide sleeve 21;

[0044] At this time, the vibration plate 3 is controlled to drive the nut to discharge, and the nut moves downward along the straight vibration track 4. The nut moves away from the straight vibration track 4 and falls into the positioning hole 20 on the transfer plate 17, and the transfer cylinder 15 is controlled to drive the transfer plate 17 and the stop bar 18 to move outward. The transfer plate 17 drives the positioning hole 20 and the nut to move outward to align with the nut push rod 19 and the nut guide sleeve 21, and the stop bar 18 moves outward to block the straight vibration track 4 to prevent the nut from falling continuously downward.

[0045] Then, the push cylinder 16 is controlled to drive the nut push rod 19 to move upward, and the nut push rod 19 moves upward to push the nut upward, and the nut passes through the nut guide sleeve 21 and enters the placement hole 95. When the nut enters the placement hole 95, the limiting ball 96 is squeezed and elastically deformed. When the nut completes entering the inner side of the placement hole 95, the limiting ball 96 clamps the nut;

[0046] Then, the six-axis robot 6 is controlled to drive the mounting frame 8 and the pick-and-place mechanism to move as a whole to the top of the mold 11, and the six-axis robot 6 is controlled to drive the mounting frame 8 to flip so that the clamping claw cylinder 91 faces downward, and then the six-axis robot 6 is controlled to drive the mounting frame 8 and the clamping claw cylinder 91 to move downward, and the product with the nut in the mold 11 is taken out by the clamping claw cylinder;

[0047] Then, the six-axis robot 6 is controlled again to drive the mounting frame 8 to flip, the end face of the feeding cylinder 92 faces downward, the six-axis robot 6 drives the vertical plate 94 and the nut to move into the mold 11, and the six-axis robot 6 is placed at an appropriate position facing the mold 11, the feeding cylinder 92 is controlled to drive the pushing frame 93 to move forward, the pushing frame 93 moves in the placement hole 95 to push the nut out, and the pushed nut falls into the mold 11, and the driving motor 13 is controlled to drive the rotating disk 10 to rotate, and the rotating disk 13 drives the mold 11 to rotate to the bottom of the vertical injection molding machine 12, and the vertical injection molding machine 12 cooperates with the mold The mold 11 is used to complete the product injection molding. Since nuts are pre-embedded in the mold 11, the injection-molded product has nuts. The product with nuts taken out by the six-axis robot 6 is moved to the automatic detector 5, and the automatic detector 5 detects whether the product has nuts. If the nuts are missing, the product is discarded. The product with nuts is placed on the transmission equipment by the six-axis robot 6 for transmission. After the product is placed, the six-axis robot 6 is controlled again to drive the mounting frame 8, the vertical plate 94 and the placement hole 95 to face the nut guide sleeve 21 to take out the next nut to repeat the next cycle.
