Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Please refer to Figure 1-10 A blow-molded part trimming, cooling, and stacking integrated system, including trimming mechanism, cooling mechanism and stacking mechanism; The cooling mechanism includes a first base 1, and a cooling fixing frame 25 is fixedly connected to the right side of the top of the first base 1. Multiple sets of cooling fans 26 are installed inside the cooling fixing frame 25. The end of the cooling fixing frame 25 near the trimming mechanism is the proximal end, one side of the proximal end is the loading side, and the other side of the proximal end is the unloading side. Multiple sets of circulating cooling trays 17 are provided on the cooling fixing frame 25. The circulating cooling trays 17 can rotate and circulate on the cooling fixing frame 25 to send the trimmed workpiece from the loading side to the unloading side after rotation. The trimming mechanism includes a robotic arm 40 and a trimming device disposed beside the robotic arm 40. The trimming device includes a second base 2, with a trimming operation platform 3 on top of the second base 2. Two sets of first electric cylinders 4 are installed at the bottom of the second base 2 to drive the trimming operation platform 3 to move up and down. Side support plates 5 are fixedly connected to the left and right sides of the top of the second base 2. First slide rails 6 are fixedly connected to the two sides inside the side support plates 5. A ball screw 7 is movably connected to the middle position inside the side support plates 5. A servo motor 8 is installed at the bottom of the side support plates 5. A cutting plate 9 is disposed above the side support plates 5. A bearing slider 11 is fixedly connected to the middle position of the bottom of the cutting plate 9. First sliders 10 are fixedly connected to the two sides of the bottom of the cutting plate 9. The cutting plate 9 can slide towards or away from the trimming operation platform 3. The robotic arm 40 has a clamp that can clamp and send the workpiece to be trimmed onto the trimming operation platform 3. The stacking mechanism includes a transfer component and a stacking component. The transfer component is used to transfer the workpiece from the unloading side, and the stacking component is used to stack the workpiece.

[0021] During operation, the robot arm 40 grips the workpiece to be trimmed and places it flat on the trimming operation platform 3. Then, the first electric cylinder 4 drives the trimming operation platform 3 to descend. After that, the two cutting plates 9 on the two side support plates 5 slide out towards the trimming operation platform 3. The inner edge of the cutting plate 9 is attached to the outer edge of the trimming operation platform 3 and is located above the outer edge of the workpiece to be trimmed. Then, the trimming operation platform 3 rises. In this way, the trimming operation platform 3 in the middle and the cutting plates 9 on both sides cooperate to cut the outer edge of the workpiece to be trimmed. Specifically, the outer edge of the workpiece to be trimmed is located on the outer periphery of the trimming operation platform 3. In this way, the outer edge of the workpiece to be trimmed is cut off. Then, the gripper of the robot arm 40 extends forward to clamp the cut outer edge and tears and transports the cut edge material away from the cutting plate around the outer periphery of the trimming operation platform 3. Thus, the trimming of the injection molded part is completed. Afterwards, the robot arm 40 sends the cut workpiece to the circulating cooling chassis 17 of the first base. The circulating cooling chassis 17 can rotate and circulate on the cooling fixed frame 25. During the circulation, the cooling fan 26 cools the workpiece. After the workpiece is cut, it is sent from the loading side to the unloading side after rotation and is cooled. Afterwards, the transfer component transfers the workpiece from the unloading side, and the stacking component stacks the workpiece.

[0022] This invention utilizes a robotic arm 40 to grip and transport the workpiece to be trimmed, then employs the staggered cooperation between the trimming platform 3 and a pair of cutting plates 9 to achieve trimming, followed by the robotic arm 40 gripping and tearing the trimmed edges. The workpiece is cooled by the rotary circulation of the cooling chassis 17 and the cooling fan 26. An initial transfer component is used for the initial transfer, and a stacking component is used for stacking the workpieces. This invention achieves fully automated production line operation for trimming, cooling, and stacking, significantly improving the degree of automation, completely eliminating reliance on manual labor, significantly enhancing the automation level and continuous production capacity of the production line, and significantly increasing production efficiency. Simultaneously, it reduces high-intensity repetitive manual labor, lowers the labor intensity of operators, helps improve the working environment, and enhances production safety and humanization.

The integrated system for edge trimming, cooling, and stacking of blow-molded parts according to claim 7, characterized in that: The threads inside the second internal thread slider (28) match the threads inside the screw of the second single-axis servo drive unit (27), and the second internal thread slider (28) can slide back and forth along the outside of the second single-axis servo drive unit (27).

9. The integrated system for edge trimming, cooling, and stacking of blow-molded parts according to claim 7, characterized in that: The stacking assembly includes a stacking actuator (70) and a plurality of stacking boxes (50) disposed on the side of the conveyor belt (35) away from the first base (1). The stacking actuator (70) is used to transfer the workpiece located at the tail of the conveyor belt (35) into the stacking box (50). It can move laterally between above the tail of the conveyor belt (35) and above the stacking point, move vertically at the tail of the conveyor belt to pick up the workpiece located at the tail of the conveyor belt (35), or move vertically at the stacking point to place the workpiece into the stacking box (50) placed in the stacking point. At least one of the plurality of stacking boxes (50) is located in the stacking point.

10. The integrated system for edge trimming, cooling, and stacking of blow-molded parts according to claim 9, characterized in that: The conveyor belt (35) has a stacking area (60) on the side away from the first base (1). There are three stacking boxes (50) in the stacking area (60). Any stacking box (50) can move cyclically along the rectangular travel route in the stacking area (60), and the stacking point is located in the rectangular travel route.
