The square tube frame 63, serving as the basic support frame of the entire conveying mechanism 6, is welded from high-strength, high-rigidity square tube material, possessing excellent resistance to deformation and stability. This ensures that the entire conveying mechanism 6 will not shake due to external forces or vibrations during operation, thereby guaranteeing the accuracy and reliability of the conveying process. The linear motor 64 and the slide rail 65 are installed side-by-side on the inner end of the square tube frame 63. The linear motor 64, as an advanced drive device, has advantages such as high precision, high speed, and high response, and can power the first variable-pitch manipulator 61 and the second variable-pitch manipulator 62. The robotic arm 62 provides powerful power support, enabling it to move quickly and accurately in the horizontal direction. The slide rail 65 adopts a high-precision linear guide, which has the characteristics of low friction and high stability. It can provide precise guidance for the sliding of the first slider 610 and the second slider 611, ensuring that the first variable pitch robotic arm 61 and the second variable pitch robotic arm 62 maintain linear motion during movement without deviation or vibration. The slide rail 65 is equipped with the first slider 610 and the second slider 611, which are respectively connected to the first variable pitch robotic arm 61 and the second variable pitch robotic arm 62. Driven by the linear motor 64, the first variable pitch robotic arm 61 and the second variable pitch robotic arm 62 move in the horizontal direction to realize the gripping and handling of products. The cable chain groove 68 is located at the upper end of the square tube frame 63. One end of the first lateral cable chain 66 and the second lateral cable chain 67 are connected to the cable chain groove 68, and the other end of the first lateral cable chain 66 and the second lateral cable chain 67 are respectively connected to the first variable pitch robot 61 and the second variable pitch robot 62. The cable chain has good flexibility and wear resistance, and can bend and extend freely as the first variable pitch robot 61 and the second variable pitch robot 62 move. It is mainly used to protect the cables and air pipes connecting the first variable pitch robot 61, the second variable pitch robot 62 and the control system, preventing them from being worn or pulled during movement, and ensuring the normal operation of the equipment. The defective product collection box 69 is located at the rear end of the square tube frame 63.

[0055] Reference Figure 10In embodiments of this utility model, the first variable-pitch manipulator 61 and the second variable-pitch manipulator 62 have the same structure, including a connecting plate 601, a lead screw lifting adjustment assembly 602, a longitudinal guide rail 603, a longitudinal slider 604, an adjustment support 605, a suction plate 606, and a lead screw lateral adjustment assembly 607. The connecting plate 601 is fixedly connected to the first slider 610 or the second slider 611, and a support sheet metal 608 is provided at the upper end of the connecting plate 601. The support sheet metal 608 is connected to the first transverse drag chain 66 or the second transverse drag chain 67, so that the relevant cables and air pipes can be effectively protected during the movement of the manipulator. The screw lifting adjustment assembly 602 is vertically installed in the middle of the connecting plate 601. Both sides of the screw lifting adjustment assembly 602 are provided with longitudinal guide rails 603. One end of the adjusting support 605 is slidably connected to the longitudinal guide rail 603 via the longitudinal slider 604, providing precise and stable guidance for the sliding of the longitudinal slider 604. This allows the adjusting support 605 to slide smoothly along the vertical direction under the guidance of the longitudinal guide rail 603, thereby adjusting the position and height of the suction plate 606. Furthermore, the screw lifting adjustment assembly 602... The system includes a lifting adjustment block 609, which is fixedly connected to the adjustment support 605. When the lead screw lifting adjustment assembly 602 is activated, the lead screw rotates, causing the lifting adjustment block 609 to move up and down, thereby driving the adjustment support 605 to achieve up and down lifting motion, thus meeting the handling needs of products of different heights. A lead screw lateral adjustment assembly 607 is horizontally mounted on the adjustment support 605. Multiple suction plates 606 are spaced apart below the lead screw lateral adjustment assembly 607, and a sliding rail is provided below the adjustment support 605. The multiple suction plates 606 are connected to the sliding rail in a specific layout. Specifically, the middle suction plate... Position 606 is fixed, while the suction plates 606 on both sides are slidably connected to the sliding rail and can move horizontally. The lead screw horizontal adjustment component 607 adopts a lead screw design with positive and negative threads. When the lead screw horizontal adjustment component 607 is activated, the lead screw starts to rotate. Due to the characteristics of the positive and negative threads, the suction plates 606 on both sides will adjust their positions in opposite directions in the horizontal direction along the sliding rail under the drive of the lead screw nut. This allows the suction plates 606 to accurately align with products at different positions. Regardless of the change in the distance between products, it can flexibly grasp and transport products with different distances, further improving the working efficiency and accuracy of the robot.

[0056] Reference Figures 11 to 14In the embodiments of this utility model, the stacking platform mechanism 7, as a core component of the entire stacking process, undertakes the key tasks of accurately stacking products and ensuring stacking quality. It mainly includes a stacking table 71, a stacking tray 72, a fixed base 73, a lifting power assembly 74, and a stacking pressure pin assembly 75. The stacking tray 72 serves as the support platform for the stacking table 71. In its initial state, the stacking tray 72 is horizontal and stationary. When ready to begin stacking operations, it provides stable support for the stacking table 71. Simultaneously, multiple stacking tables 71 are carefully arranged on the stacking tray 72 according to a specific layout rule. Before actual production, workers will... According to the requirements of different product specifications in the production plan, the positions of these stacking tables 71 are flexibly adjusted, or stacking tables 71 that do not meet the specifications are replaced, to ensure that the layout of the stacking tables 71 on the stacking tray 72 can perfectly adapt to the upcoming stacking operation. The lifting power component 74, as the power source for driving the stacking tray 72 to rise and fall, is installed on the fixed base 73, and the upper end of the lifting power component 74 is connected to the stacking tray 72. During the stacking process, when it is necessary to change the stacking height, the lifting power component 74 starts, and its internal power element generates power, which is transmitted to the upper end connected to the stacking tray 72 through a specific transmission structure. With the continuous input of power, the stacking tray 72, under the precise lifting control of the lifting power component 74, begins to drive the stacking tables 71 to move smoothly and accurately in the vertical direction. For example, when it is necessary to stack the next layer of products, the lifting power component 74 controls the stacking platform 72 to descend a certain distance, so that the stacking platform 71 reaches a suitable height position to place the new products; conversely, after one layer of stacking is completed, the lifting power component 74 will control the stacking platform 72 to rise again to prepare for the next layer of stacking, thereby realizing stacking operations at different height positions.

[0057] The stacking needle assembly 75 is disposed between the stacking platform 72 and the fixed base 73. The stacking needle assembly 75 includes a lifting connecting seat 76, a crankshaft lifting assembly 77, and a needle adjustment assembly 78. Both ends of the lifting connecting seat 76 are connected to the fixed base 73 to ensure the stacking needle assembly 75 remains stable during operation. The crankshaft lifting assembly 77 is mounted on the fixed base 73, and its upper end is fixedly connected to the lifting connecting seat 76, driving the lifting connecting seat 76 to move up and down. The needle adjustment assembly 78 is connected to the lifting connecting seat 76. During the stacking process, operators can adjust the needle adjustment assembly 78 according to the actual stacking conditions, such as the shape of the product and the stacking method. Through the precision adjustment structure inside the needle adjustment assembly 78, the position of the stacking needles 781 can be precisely adjusted. For example, when it is necessary to adjust the position of the stacking pressure needle 781 in the horizontal direction, the operator can rotate or slide the corresponding part on the pressure needle adjustment assembly 78 to move the stacking pressure needle 781 accurately to the target position, thereby ensuring that the stacking pressure needle 781 can accurately press on the product during the stacking process, ensuring the quality and stability of the stacking.

[0058] The crankshaft lifting assembly 77 specifically includes a drive motor 771, a motor mounting base 772, a crankshaft seat 773, a crankshaft 774, and a crankshaft connecting plate 775. The drive motor 771 is fixedly connected to the fixed base 73 via the motor mounting base 772, ensuring that the drive motor 771 will not shake or shift during operation. The crankshaft 774 is connected to the drive end of the drive motor 771, and the crankshaft seat 773 is rotatably supported on the outside of the crankshaft 774. When the drive motor 771 starts, it can drive the crankshaft 774 to rotate. The crankshaft 774 is rotatably connected to the lower end of the crankshaft connecting plate 775 via fasteners, and the upper end of the crankshaft connecting plate 775 is rotatably connected to the lifting connecting seat 76. During the rotation of the crankshaft 774, the rotational motion is converted into the up-and-down lifting motion of the lifting connecting seat 76 through the crankshaft connecting plate 775, thereby realizing the overall lifting of the stacked pressure needle assembly 75.

[0059] The pressure needle adjustment assembly 78 specifically includes a stacked pressure needle 781, a pressure needle plate 782, a second drive motor 783, a left-hand lead screw 784, a right-hand lead screw 785, a lead screw transmission seat 786, and a lifting cylinder 787. The second drive motor 783 is fixedly connected to the middle of the lifting connecting seat 76, and the left-hand lead screw 784 and the right-hand lead screw 785 are respectively connected to the two ends of the second drive motor 783. Both the second drive motor 783 and the left-hand lead screw 784 are provided with lead screw transmission seats 786. Employing a high-precision threaded structure, the screw achieves smooth and accurate linear motion during rotation. A lifting cylinder 787 is vertically mounted on the screw drive seat 786, with its extended end connected to the pressure needle plate 782. The pressure needle plate 782 has multiple stacked pressure needles 781 spaced apart. These stacked pressure needles 781 are made of high-strength, high-hardness materials, possessing good elasticity and wear resistance, and can apply appropriate pressure to the product during stacking, ensuring product position stability. When the drive motor 783 starts, it drives the left-hand screw 784 and the right-hand screw 785 to rotate simultaneously. Due to the opposite thread directions, the two screw drive seats 786 move in opposite directions, thereby achieving lateral adjustment of the position of the stacked pressure needles 781 on the pressure needle plate 782. Simultaneously, the extension and retraction of the lifting cylinder 787 allows for height adjustment of the stacked pressure needles 781 to meet the stacking requirements of products of different specifications.

[0060] Through the precise combination and coordinated operation of the above components, the stacking platform mechanism 7 can achieve precise lifting and lowering control of the stacking table 71 and flexible adjustment of the position and pressure of the stacking pressure needle 781, thereby ensuring that the products can be stacked accurately and stably during the stacking process, greatly improving the stacking quality and production efficiency, and providing a strong guarantee for the smooth operation of the entire production process.
