DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0032] The embodiment of the present application discloses a system for separating injection molded parts and waste materials.

[0033] Reference Figure 2 and Figure 3 , a system for separating injection molded parts from waste, includes a manipulator 1, the manipulator 1 includes a mounting plate 2 and a vertical arm 12, a suction cup 21 and a cutter 22 are provided on one side of the mounting plate 2, and the lower end of the vertical arm 12 is rotatably connected to the side of the mounting plate 2 away from the suction cup 21. The side of the vertical arm 12 away from the mounting plate 2 is rotatably connected to a second cylinder 32, and the output shaft of the second cylinder 32 is rotatably connected to the mounting plate 2. This structure enables the mounting plate 2 to be rotated and adjusted at multiple angles driven by the vertical arm 12, so as to adapt to different work requirements. The axes of the rotation axis of the vertical arm 12 and the mounting plate 2, the rotation axis of the vertical arm 12 and the second cylinder 32, and the rotation axis of the second cylinder 32 and the mounting plate 2 are also parallel to each other to ensure the stable movement of the manipulator 1.

[0034] Reference Figure 2 and Figure 3 , the output shaft of the third cylinder 13 extends to make the side of the mounting plate 2 with the suction cup 21 in a vertical state, the manipulator 1 moves to drive the mounting plate 2 to move to the inside of the injection molding machine 5, and controls the suction cup 21 to start. The suction cup 21 includes a first suction cup 211 and a second suction cup 212, so that the first suction cup 211 absorbs the waste 100, and the second suction cup 212 absorbs the injection molded part 110. The cutter 22 includes a first cylinder 221 and a blade 222. The side of the first cylinder 221 away from the cylinder output shaft is fixedly connected to the mounting plate 2, and the output shaft of the first cylinder 221 is fixedly connected to the blade 222. The first cylinder 221 drives the blade 222 to move, so as to cut and separate the waste 100 and the injection molded part 110. After separation, the manipulator 1 drives the mounting plate 2 to take out the waste 100 and the injection molded part 110.

[0035] Reference Figure 2 and Figure 4A waste box 3 is provided below the manipulator 1. The upper end of the waste box 3 is open. A box cover 31 is provided at the upper end of the waste box 3. The box cover 31 is hinged to the side of the waste box 3 by hinges, so that the box cover 31 can be opened and closed flexibly. A handle 311 is provided on the side of the box cover 31 away from the waste box 3 for easy manual operation. However, in the present system, the opening and closing of the box cover 31 is mainly realized by automatic control.

[0036] Reference Figure 2 and Figure 4 , one side of the waste box 3 is rotatably connected with the third cylinder 13, and the output shaft of the third cylinder 13 is rotatably connected with the box cover 31. The axes of the hinge axis of the box cover 31 and the waste box 3, the rotation axis of the waste box 3 and the third cylinder 13, and the rotation axis of the third cylinder 13 and the box cover 31 are parallel to each other, which ensures that the box cover 31 can move smoothly and accurately. A signal receiving device is provided on the third cylinder 13, and a sensor 11 is provided on the moving arm of the manipulator 1. The signal receiving device and the sensor 11 are connected through a signal line 322, thereby forming a closed-loop control system. When the manipulator 1 moves to the top of the waste box 3 with the waste 100, the sensor 11 will send a signal, and the signal will be transmitted to the signal receiving device through the signal line 322. After receiving the signal, the signal receiving device will control the third cylinder 13 to work, thereby driving the box cover 31 to slowly open, close the first suction cup 211, and the waste 100 will fall into the waste box 3 from above.

[0037] Reference Figure 2 and Figure 3 , a conveyor belt 4 is provided on one side of the waste bin 3, the manipulator 1 drives the mounting plate 2 with only the injection molded part 110 left to move above the feeding end of the conveyor belt, closes the second suction cup 212, and the injection molded part 110 falls onto the conveyor belt, and the conveyor belt 4 sends the separated injection molded part 110 to the next process. The waste bin 3 and the feeding end of the conveyor belt are designed to be within the moving range of the manipulator 1 to ensure that the manipulator 1 can smoothly put the waste 100 and the injection molded part 110 into the waste bin 3 and the conveyor belt 4 respectively.

[0038] Reference Figure 2 and Figure 4 The lower end surface of the waste bin 3 is provided with a leg 33 for supporting the entire waste bin 3. An outlet is provided at the lower end of the waste bin 3 on the side away from the conveyor belt 4, and a baffle 34 is provided at the outlet to block the outlet. When a certain amount of waste 100 accumulates in the waste bin 3, the waste 100 can be discharged from the outlet by opening the baffle 34. The baffle 34 is hinged to the side of the waste bin 3 by a hinge to facilitate its flexible rotation. At the same time, a locking device 35 is provided on the side of the baffle 34 away from the hinge, and the locking device 35 is fixedly connected to the waste bin 3 on the side away from the baffle 34 to ensure that the baffle 34 can firmly close the outlet when the baffle 34 does not need to be opened.

[0039] The implementation principle of the system for separating injection molded parts and waste materials in the embodiment of the present application is as follows: after the injection molding machine 5 completes the injection molding, the manipulator 1 respectively absorbs the waste material 100 and the injection molded part 110 through the suction cup 21. Then, the cutter 22 moves up and down under the drive of the first cylinder 221 to cut and separate the waste material 100 and the injection molded part 110. After the separation is completed, the manipulator 1 moves to the top of the waste bin 3, at which time the sensor 11 sends a signal and transmits it to the signal receiving device through the signal line 322. After receiving the signal, the signal receiving device controls the third cylinder 13 to work, thereby driving the box cover 31 to open. Then, the waste material 100 falls from the first suction cup 211 and enters the waste bin 3. Subsequently, the manipulator 1 continues to move to the top of the conveyor belt 4 with the injection molded part 110, the second suction cup 212 stops working, and the injection molded part 110 falls onto the conveyor belt 4 and is sent to the next process. The whole process realizes the automatic, efficient and precise separation of the waste material 100 and the injection molded part 110.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
