The discharge unit includes a vibrating turntable 10, a feeding pipe 2, a receiving platform 3, a drive assembly 4, and a controller, all mounted on a frame 6. The vibrating turntable 10 is fixedly connected to the feeding pipe 2 and is used to transfer neatly arranged inserts 7 into the feeding pipe 2. The receiving platform 3 is located below the feeding pipe 2 and is used to receive the inserts 7. The drive assembly 4 is electrically connected to the controller and is used to drive the receiving block 3 and deliver the inserts 7 on the receiving block 3 to the picking position. The feeding unit is electrically connected to the controller and includes a gripper assembly 8. The gripper assembly 8 can grasp the inserts 7 located at the picking position and install the inserts 7 into the die-casting mold in the die-casting machine, and can also remove the product with the inserts 7 after injection molding.

[0031] like Figure 2 As shown, the vibratory turntable 10 is fixedly connected to the fixed platform 65 of the frame 6 by screws (not shown in the figure). A photoelectric detector (not shown in the figure) is installed on the vibratory turntable 10 to reject inserts with incorrect orientation, ensuring that the inserts 7 enter the feeding pipe 2 in the correct orientation. Before the inserts 7 enter the feeding pipe 2, the photoelectric detector checks the orientation of the inserts 7, ensuring that the arrangement direction of the inserts 7 is correct, preventing subsequent processes from being affected by incorrect orientation, and improving the accuracy of feeding.

[0032] The feeding end 210 of the feeding pipe 2 is fixedly connected with the discharge port of the vibrating turntable 10, and the discharging end 220 of the feeding pipe 2 is suspended. In the embodiment, the feeding pipe 2 is an L-shaped pipe, the feeding end 210 is located in the horizontal feeding section 21, and the discharging end 220 is located in the vertical discharging end. It is worth noting that there is enough space at the turning of the feeding pipe 2 to enable the insert 7 to be switched from the horizontal conveying state to the vertical conveying state.

[0033] The discharging unit further comprises a linear vibrator 11. The linear vibrator 11 is fixedly connected with the feeding pipe 2, and is used to drive the insert 7 in the feeding pipe 2 to move from the feeding end 210 to the discharging end 220.

The cutoff cylinder 23 is fixedly connected with the second support 221, and the piston rod 231 is slidably accommodated in the first and second through holes 222 and 223. The controller is electrically connected with the cutoff cylinder 23 and controls the cutoff cylinder 23 to slide the piston rod 231. When the cutoff cylinder 23 pushes the piston rod 231 to extend, the end of the piston rod 231 is accommodated in the second through hole 223, the discharging end 220 is in the cutoff state, and the insert 7 cannot slide out of the discharging end 220. When the cutoff cylinder 23 drives the piston rod 231 to retract, the end of the piston rod 131 is accommodated in the first through hole 222, the discharging end 220 is in the open state, and the insert 7 can slide out of the discharging end 220. By setting the cutoff cylinder 23 at the discharging end 220 of the feeding pipe 2, the opening and cutoff of the discharging end 220 are controlled to control the number of inserts 7 sliding out, preventing multiple inserts 7 from sliding out at a time and affecting the production rhythm.

In the embodiment, the second driver 42 is preferably a pneumatic cylinder (not shown in the figure). The controller is electrically connected with the second driver 42 and controls the second driver 42 to drive the second slide block 45 to move, thereby driving the receiving table 3 to move.

Figure 5 The receiving table 3 is provided with a photoelectric sensor 31, which is used for detecting whether the insert 7 is mounted in the mounting station. The mounting station is the receiving groove 30 opened on the receiving table 3, and the insert 7 is located in the receiving groove 30 and at least partially exposed outside the receiving table 3 for being grabbed by the jaw assembly 8. The photoelectric sensor 31 is installed on the side wall of the receiving groove 30. The photoelectric sensor 31 is electrically connected with the controller for detecting whether the insert 7 is mounted in the receiving groove and transmitting the detection signal to the controller.

[0038] Specifically, the at least one mounting station comprises a plurality of receiving grooves 30 arranged along the movement direction of the receiving table 3. In the embodiment, the plurality of receiving grooves 30 specifically comprises two receiving grooves 30.

In this embodiment, the clamping pipe 810 is an eight-jaw pipe cavity for clamping the insert 7; and the ejection cylinder 811 has a self-checking function for detecting whether the insert 7 is installed in place. Specifically, the ejection cylinder 811 is electrically connected with the controller, when the ejection cylinder 811 detects that the insert 7 is not inlaid in place or the insert 7 is missing, the ejection cylinder 811 sends a signal to the controller to force the robot to alarm and stop.

[0042] The second gripper 82 includes a plurality of clamping blocks 821 uniformly distributed in the circumferential direction, which are used to take out the product with the insert 7 after injection molding. In this embodiment, the clamping mode of the second gripper 82 is three-jaw clamping, so the plurality of clamping blocks 821 are specifically three clamping blocks 821.

[0043] In operation, the vibration turntable 10 arranges the inserts 7 in a fixed direction by vibration and then sends them into the feeding pipe 2 at the feeding end 210. The inserts 7 slide from the feeding end 210 to the discharging end 220 under the vibration of the straight vibrator 11. In the initial state, the cutoff cylinder 23 at the discharging end 220 is in the extended state to prevent the inserts 7 from falling. And the receiving table 3 is driven by the first driver 41 to make the receiving groove 30 at the front end in the running direction on the receiving table 3 located directly below the discharging end 220 of the feeding pipe 2. At this time, the cutoff cylinder 23 is retracted, the insert 7 slides out of the discharging end 220 and is loaded into the receiving groove 30 at the front end in the running direction. During the loading of the insert 7 into the receiving groove 30, the cutoff cylinder 23 returns to the extended state. The first driver 41 drives the receiving table 3 to move along the direction of the slide rail 43 until the receiving groove 30 at the rear end in the running direction on the receiving table 3 is located directly below the discharging end 220 of the feeding pipe 2. At this time, the cutoff cylinder 23 is retracted, the insert 7 slides out of the discharging end 220 and is loaded into the receiving groove 30 at the right end in the running direction. During the loading of the insert 7 into the receiving groove 30, the cutoff cylinder 23 returns to the extended state. The second driver 42 drives the first driver 41 to move along the direction of the slide rail 43 until the receiving table 3 is located at the taking position.

[0044] The controller controls the robot to operate, the robot drives the first gripper 81 to move to a grabbing position, and the clamping pipe 810 is sleeved on the insert 7 to accurately take out the insert 7.
