[0016] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] Please refer to Figures 1 to 3 A stacking machine for assisting a robotic arm in adjusting the orientation of injection-molded products in a turntable 4, comprising: The end face is used for placing the turntable 4 on the workbench 1; The receiving platform 2 is fixedly connected to the workbench 1 and located above the workbench 1; The suction cup 3 is rotatably connected to the receiving platform 2 to control the flipping of the injection molded product.

[0018] As can be seen from the above description, the beneficial effects of this utility model are as follows: By setting a receiving platform 2 on the workbench 1 and configuring a rotatable suction cup 3 on the receiving platform 2, the flipping operation of injection-molded products in the turnover tray 4 is realized. This structure can automatically adjust the orientation of injection-molded products in conjunction with a robotic arm during the stacking process, avoiding the inefficiency and instability of manual flipping, ensuring that the products are placed in the same direction in the turnover tray 4, thereby facilitating subsequent stacking, packaging and transportation, and significantly improving the level of automation and production efficiency.

[0019] In this embodiment, the rotatable connection between the suction cup 3 and the receiving platform 2 can be achieved using a rotary drive assembly. The rotary drive assembly includes a rotating shaft mounted below the receiving platform 2, a suction cup bracket 31 fixedly connected to the rotating shaft, and a rotary drive component 32 for driving the rotating shaft. The rotating shaft is supported within the rotating shaft seat of the receiving platform 2 by rolling bearings at both ends, ensuring smooth rotation and low frictional resistance. The rotary drive component 32 can be an electric rotary servo motor or a pneumatic swing cylinder, with its output end connected to the rotating shaft via a coupling. When the drive component actuates, it drives the rotating shaft and the suction cup bracket 31 on it to rotate synchronously, realizing the flipping motion of the suction cup 3 in a horizontal or vertical plane.

[0020] The suction cup 3 is fixed to the lower end face of the suction cup bracket 31 and connected to the vacuum pipeline via a vacuum generator. It adsorbs the injection-molded product under vacuum and places the product when the vacuum is released. To ensure flipping accuracy, an angle limit switch or encoder is installed on the rotary drive assembly to detect the current rotation angle position of the suction cup 3, achieving precise 0° and 180° positioning. This structure enables smooth flipping while the product is adsorbed, adapting to injection-molded products of different sizes and weights. Orientation adjustment is completed with the assistance of a robotic arm, improving the reliability and stability of automated operation.

[0021] Please refer to Figures 4 to 6 In some embodiments, a positioning component 5 is also included, which includes a lifting plate 51 and a first driving member 52; the lifting plate 51 abuts against the bottom of the turntable 4; the first driving member 52 is fixedly connected to the worktable 1 and is drivenly connected to the lifting plate 51 to control the lifting plate 51 to move closer to or away from the worktable 1.

[0022] As can be seen from the above description, by setting the lifting plate 51 and the first driving component 52 in the positioning component 5, the lifting plate 51 can lift the turntable 4 and rise to a suitable height, thereby providing sufficient operating space for the robotic arm to grip or flip products. This not only improves the flexibility of operation, but also reduces the difficulty of the robotic arm working in a low and narrow space, reduces the risk of collision with the robotic arm, and improves the safety and stability of the production process.

[0023] Specifically, the first driving component 52 is used to drive the lifting plate 51 to move up and down vertically. In this embodiment, the first driving component 52 is a servo electric push rod, the main body of which is fixedly installed below the worktable 1, and its telescopic end is rigidly connected to the bottom surface of the lifting plate 51. When the servo motor controls the push rod to extend, the lifting plate 51 is lifted to raise the turntable 4; when the push rod retracts, the lifting plate 51 descends, causing the turntable 4 to return to the position of the worktable 1. Servo control enables precise height adjustment and can respond quickly when switching between different product heights.

[0024] Please refer to Figure 5In some embodiments, the positioning component 5 further includes a guide plate 53, which is fixedly connected to the worktable 1 and distributed on the edge of the end face of the worktable 1.

[0025] As can be seen from the above description, adding guide plates 53 fixed to the worktable 1 to the positioning component 5 and distributing them on the edge of the end face of the worktable 1 can effectively prevent the turnover tray 4 from shifting position during lifting or robotic arm operation, ensuring that the turnover tray 4 is always in the working area where the robotic arm can accurately position it, thereby improving the operation accuracy and stability.

[0026] Please refer to Figure 5 In some embodiments, the angle between the guide plate 53 and the end face of the worktable 1 is an acute angle.

[0027] As can be seen from the above description, the angle between the guide plate 53 and the end face of the worktable 1 is designed to be an acute angle, which can form a guiding wedge effect when the turntable 4 contacts the guide plate 53, making it easier for the turntable 4 to be guided to the accurate position, thereby further improving the positioning efficiency and accuracy.

[0028] Please refer to Figure 5 In some embodiments, the positioning component 5 further includes clamping members 54 symmetrically arranged on both sides of the lifting plate 51. The clamping members 54 include a second driving member 541 and a clamping block 542. The second driving member 541 is fixedly connected to the worktable 1 and is throttle connected to the clamping block 542 to control the clamping block 542 to move closer to or away from the turntable 4.

[0029] As can be seen from the above description, by setting symmetrical clamping members 54 (including the second driving member 541 and the clamping block 542) on both sides of the lifting plate 51, the turntable 4 can be clamped and fixed after being lifted, so as to prevent it from shaking or shifting during flipping, shearing or placement operations.

[0030] Specifically, the second driving component 541 is used to drive the clamping component 54 to clamp or release the turnover tray 4. In this embodiment, the second driving component 541 is a bidirectional cylinder, with the cylinder body fixed on the worktable 1 and the piston rod connected to the clamping block 542. When the cylinder pushes inward, the left and right clamping blocks 542 move simultaneously toward the center of the turnover tray 4, clamping the turnover tray 4; when the cylinder retracts outward, the clamping blocks 542 release, achieving rapid loading and unloading. This structure has a fast response, stable clamping force, and can be used with a buffer device to prevent damage to the turnover tray 4.

[0031] Please refer to Figure 7 In some embodiments, the positioning component 5 further includes a sensor 55; the sensor 55 is fixedly connected to the worktable 1 to sense the position of the turntable 4 on the worktable 1.

[0032] As described above, by adding sensor 55 to positioning component 5, the position of turntable 4 on workbench 1 can be detected in real time, realizing position monitoring and feedback control. When turntable 4 deviates from the set position, the system can promptly adjust the position or issue an alarm, thereby reducing the error rate and improving the automation and intelligence level of the entire system. Specifically, sensor 55 is a light sensor 55.

[0033] Please refer to Figure 7 In some embodiments, a conveyor chain 6 is also included, which is slidably disposed on both sides of the workbench 1 to transport the turntable 4 along the extension direction of the conveyor chain 6.

[0034] As can be seen from the above description, by setting sliding conveyor chains 6 on both sides of the workbench 1, the turnover tray 4 can be automatically transported along the chain direction, reducing manual handling, improving the efficiency of turnover tray 4 in transferring between different workstations, and reducing the intensity of manual labor.

[0035] Please refer to Figure 8 In some embodiments, a discharge assembly 7 is also included, which includes a discharge platform 71, a discharge slide rail 72, and a third drive member 73. The discharge slide rail 72 is connected to the side wall of the worktable 1, the discharge platform 71 is located at the end of the conveyor chain 6 and is slidably connected to the discharge slide rail 72, and the third drive member 73 is connected to the discharge slide rail 72 to control the discharge platform 71 to move along the discharge slide rail 72.

[0036] As described above, the discharge assembly 7 (including the discharge platform 71, the discharge slide rail 72, and the third drive component 73) can automatically move the turntable 4 at the end of the conveyor chain 6 to a designated position. This structure not only facilitates the centralized collection and stacking of the finished product turntable 4, but also allows for seamless integration with downstream processes, further improving the continuity and smoothness of the production line.

[0037] Please refer to Figure 8 In some embodiments, a feeding assembly 8 is also included, which includes a feeding table 81, a feeding slide rail 82, and a fourth driving member 83; the feeding slide rail 82 is connected to the side wall of the worktable 1, the feeding table 81 is located at the beginning of the conveyor chain 6 and is slidably connected to the feeding slide rail 82, and the fourth driving member 83 is connected to the feeding slide rail 82 to control the feeding table 81 to move along the feeding slide rail 82.

[0038] As described above, the feeding assembly 8 (including a feeding table 81, a feeding slide rail 82, and a fourth drive component 83) can automatically feed empty turntables 4 into the working area at the beginning of the conveyor chain 6. This automatic feeding method avoids the need for frequent manual placement of the turntables 4, improves production cycle time, and ensures production continuity.

[0039] Specifically, the third driving component 73 and the fourth driving component 83 are both stepper motors driven by a gear and rack transmission mechanism. The stepper motor is fixed at the end of the slide rail, and the motor output shaft drives the pinion to rotate. The pinion meshes with the rack fixed at the bottom of the discharge table 71, thereby realizing the linear movement of the table along the slide rail.

[0040] Please refer to Figure 9 In some embodiments, the device also includes a shearing assembly 9, which includes a protective cover 91, a pneumatic shearing pliers 92, and a mounting base 93. The mounting base is fixedly connected to the edge of the workbench 1 near the receiving platform 2. The pneumatic shearing pliers 92 is assembled and connected to the mounting base 93. The protective cover 91 is located around the pneumatic shearing pliers 92 and is fixedly connected to the workbench 1.

[0041] Specifically, please refer to Figure 10 The injection molded product 10 generally has a gate 11 generated during the injection molding process. With the help of the robotic arm and the shearing assembly 9, the gate 11 of the injection molded product 10 is cut off to assist in the automated molding of the product.

[0042] As described above, by installing the shearing assembly 9 (protective cover 91, pneumatic shearing 92, and mounting base 93) on the workbench 1 near the receiving table 2, the gate of the injection-molded product can be automatically cut off with the assistance of a robotic arm. The protective cover 91 effectively prevents splashing contact at the cut area, improving safety. This structure can complete both product flipping and gate shearing in one operation, reducing inter-process transfers and improving production efficiency.

[0043] Embodiment 1 of this utility model is as follows: Please refer to Figures 1 to 3 This utility model provides a case stacking machine to assist a robotic arm in adjusting the orientation of injection-molded products in a turntable 4. The case stacking machine includes a worktable 1, the end face of which is used to place the turntable 4; a receiving platform 2 is fixedly connected to the worktable 1 and located above the worktable 1, used to support a suction cup 3 assembly; the suction cup 3 is rotatably connected to the receiving platform 2, and can flip the suction-adsorbed injection-molded products under controlled driving action, thereby automatically adjusting the orientation of the injection-molded products during the stacking process in conjunction with the robotic arm. Please refer to [link / reference needed] for details. Figure 9 Meanwhile, a shearing assembly 9 is installed near the receiving platform 2. The shearing assembly 9 includes a mounting base 93, a protective cover 91, and a pneumatic shearing pliers 92. The mounting base 93 is fixedly connected to the worktable 1, and the pneumatic shearing pliers 92 is assembled and connected to the mounting base 93. It is used to automatically cut off the glue gate of the injection molded product with the assistance of a robotic arm. The protective cover 91 surrounds the pneumatic shearing pliers 92 and is fixedly connected to the worktable 1 to prevent splashing or accidental contact of the cutting parts, thereby improving operational safety.

[0044] Please refer to Figures 4 to 6In this embodiment, a positioning component 5 is also provided. The positioning component 5 includes a lifting plate 51 and a first driving member 52. The upper surface of the lifting plate 51 abuts against the bottom of the turntable 4. The first driving member 52 is fixedly connected to the worktable 1 and is drivenly connected to the lifting plate 51, thereby controlling the lifting plate 51 to move closer to or further away from the worktable 1 in the vertical direction, thus lifting the turntable 4. When the lifting plate 51 raises the turntable 4 to a preset height, it provides sufficient operating space for the robotic arm to grip or flip products, reducing the risk of interference for the robotic arm in the low-position area.

[0045] Please refer to Figure 5 The positioning component 5 also includes a guide plate 53 fixedly connected to the worktable 1. The guide plate 53 is distributed along the edge of the end face of the worktable 1 to prevent the turntable 4 from shifting position during lifting or flipping operations. In this embodiment, the angle between the guide plate 53 and the end face of the worktable 1 is designed to be an acute angle so that a wedge-shaped guiding effect is generated when the turntable 4 contacts the guide plate 53, helping the turntable 4 to be positioned quickly and accurately.

[0046] Please refer to Figure 5 In order to further stabilize the turntable 4, the positioning assembly 5 is provided with clamping members 54 symmetrically on both sides of the lifting plate 51. The clamping members 54 include a second driving member 541 and a clamping block 542. The second driving member 541 is fixedly installed on the workbench 1 and is connected to the clamping block 542 in a transmission manner. It can control the clamping block 542 to move closer to or away from the turntable 4, and clamp and fix the turntable 4 in the lifting state.

[0047] Please refer to Figure 7 In another refined structure, the positioning component 5 is also equipped with a sensor 55, which is fixedly connected to the worktable 1 and is used to detect the position of the turntable 4 on the worktable 1 in real time. When an offset is detected, it can send an adjustment or alarm signal to the control system to realize closed-loop position control.

[0048] Please refer to Figure 5 To achieve automatic conveying of the turnover tray 4, sliding conveyor chains 6 are provided on both sides of the workbench 1. The turnover tray 4 can be conveyed from the feeding end to the discharging end along the extension direction of the conveyor chain 6. The beginning of the conveyor chain 6 is equipped with a feeding assembly 8, which includes a feeding platform 81, a feeding slide rail 82, and a fourth drive component 83. The feeding slide rail 82 is connected to the side wall of the workbench 1, and the feeding platform 81 is slidably connected to the feeding slide rail 82. The fourth drive component 83 drives the feeding platform 81 to move along the feeding slide rail 82, thereby automatically sending the empty turnover tray 4 to the starting position of the conveyor chain 6.

[0049] Please refer to Figure 8A discharge assembly 7 is provided at the end of the conveyor chain 6. The discharge assembly 7 includes a discharge platform 71, a discharge slide rail 72, and a third drive component 73. The discharge slide rail 72 is fixed on the side wall of the workbench 1. The discharge platform 71 is slidably connected to the discharge slide rail 72. The third drive component 73 drives the discharge platform 71 to move along the discharge slide rail 72, automatically removing the turntable 4 filled with injection molded products from the end of the conveyor chain 6, which is convenient for centralized stacking or flow to the downstream process.

[0050] In summary, this utility model provides a stacking machine that integrates functions such as flipping, lifting, positioning, clamping, conveying, feeding, discharging, and shearing. It can work in conjunction with a robotic arm to automatically adjust the orientation of injection-molded products within the turntable and cut the gate, ensuring consistent placement and reducing manual intervention. Through lifting and clamping coordination, guide plate limiting, and sensor detection, precise positioning and stable fixing of the turntable are achieved. The conveyor chain, combined with feeding and discharging components, realizes an automated cycle of empty turntable supply and finished product turntable output. The shearing assembly safely and efficiently completes the shearing operation. This structure features smooth operation, high efficiency, and good stability, significantly reducing labor intensity, avoiding mixed loading and misalignment, and improving product consistency.
