[0002] In the mass production of plush toys, the automatic assembly of multiple parts is a key link to improve production efficiency. Using a quick clamping device can achieve stable clamping and precise positioning of each part of the plush toy, ensuring that the assembly process is carried out in an orderly manner, reducing errors caused by manual operation, and speeding up the assembly speed to meet the requirements of high efficiency and consistency for large-scale production. Therefore, a special quick clamping device is needed to assist in completing this process.
[0003] The suction cups of the existing device's picking components are in relatively fixed positions, making it impossible to flexibly adjust them according to the size, shape, and splicing position of the plush toy parts. When faced with parts of different sizes, the fixed suction cups are difficult to form an effective suction force, which can easily lead to unstable gripping and parts falling off. This affects the accuracy and efficiency of subsequent splicing and causes many inconveniences to production. Therefore, it is necessary to improve the above-mentioned problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Example: See Figure 1-4This utility model discloses a quick clamping device for automatic assembly of multiple parts of a rag doll, comprising two mirror-arranged support plates 1, with a center plate 9 between the opposite faces of the support plates 1. First connecting plates 4 are mirror-mounted at both ends of the top surface of the center plate 9. Guide rods 3 are symmetrically mounted on both sides of the top surface of the first connecting plates 4, and mounting plates 2 are sleeved between the guide rods 3. Multiple mounting holes are symmetrically opened at both ends of the top surface of the mounting plates 2. A hydraulic cylinder is mounted in the middle of the top surface of the mounting plates 2, with the output end of the hydraulic cylinder passing through the bottom surface of the mounting plates 2 and fixedly connected to an n-shaped connecting plate. The n-shaped connecting plate is fixedly connected to the center plate 9 by bolts. One of the two support plates 1 supports... A lifting component is installed on one side of the top surface of the support plate 1, and clamping plates 14 are installed on the bottom surface of both support plates 1 in a staggered manner; the hydraulic cylinder model is HOB40×50; the support plate 1 is made of high-strength alloy steel, which enhances the overall load-bearing capacity and structural stability of the device; this section of the structure, by setting adjustable mounting plates 2 and clamping plates 14, provides basic structural support for solving the problems of device adjustment flexibility and clamping stability, thus improving the practicality of the device; multiple fixing blocks 8 are symmetrically arranged on both sides of the center plate 9, and guide blocks 7 are fixedly connected to the fixing blocks 8; the two support plates 1 T-shaped plates are fixedly attached to the upper ends of the opposite surfaces of the T-shaped plates, and long sliding groove blocks 13 are fixedly attached to the opposite surfaces of the T-shaped plates and slidably mounted on the guide block 7. The fixing block 8 is made of cast iron, which improves the firmness of the connection with the center plate 9 and ensures the stability of the guiding process. This structure achieves precise guidance when the support plate 1 moves through the sliding cooperation between the guide block 7 and the long sliding groove block 13, improving the smoothness of the adjustment. The center plate 9 is rotatably equipped with a first gear at the center of its top surface. Two first racks 6 are meshed on both sides of the first gear, and the bottom ends of the two first racks 6 are fixedly attached to the top surfaces of the two T-shaped plates respectively. Two L-shaped fixing plates 5 are mirror-mounted on the top surface of the center plate 9. First electric push rods are staggered and oppositely mounted on the opposing surfaces of the two L-shaped fixing plates 5. Vertical blocks, corresponding to the top surfaces of the two T-shaped plates, are fixedly connected to the telescopic ends of each first electric push rod. The first electric push rod is a DTZ300 model. The first gear is made of 40Cr alloy steel, which improves wear resistance, transmission accuracy, and extends service life. This structure, driven by the first electric push rod and driven by a gear and rack, achieves synchronous reverse movement of the support plate 1, improving the efficiency and accuracy of the clamping plate 14 spacing adjustment.
[0020] In this utility model, the picking component includes a drive motor mounted on the top surface of a support plate 1. The output shaft of the drive motor is coaxially fixed to a drive gear. The lower end of the drive gear meshes with a second rack slidably disposed on the top surface of the support plate 1. A first groove is formed on the support plate 1 at the location of the second rack. A connecting frame 10 is slidably disposed within the first groove. Multiple rectangular frames are equidistantly fixed to the bottom of the connecting frame 10. A second groove is formed on the inner wall of each rectangular frame. A slider is slidably disposed at intervals within each of the second grooves. Suction cups 12 are mounted on the opposing surfaces of the sliders and the clamping plate 14. The drive motor is model YE2-100L1-4. The suction cups 12 are made of nitrile rubber. Using nitrile rubber for the suction cups 12 provides good elasticity and sealing, enhancing the adsorption force on the components. This structure, through the drive motor moving the picking component and the sliding of the sliders in the second grooves, provides the possibility for adjusting the position of the suction cups 12, improving the flexibility of picking. A rectangular frame is fixedly attached to one end of the block, and a push plate 11 is fixedly attached between the top surfaces of the rectangular frame. The telescopic end of a second electric push rod is fixedly attached to the middle of the top surface of the push plate 11, and the fixed end of the second electric push rod is installed on one side of the second rack and the rectangular frame. The model of the second electric push rod is XTL100. The push plate 11 is made of aluminum alloy, which is lightweight and has high strength, making it easy to push the slider to move flexibly. This structure achieves rapid adjustment of the position of the suction cup 12 by pushing the push plate 11 with the second electric push rod, improving the adaptability to different parts. The clamping plate 14 has multiple inclined grooves evenly spaced on its clamping surface. The clamping plate 14 is made of high manganese steel, which has high wear resistance and toughness. Combined with the inclined grooves, it can increase the friction with the parts and enhance the clamping stability. This structure increases the friction of the clamping surface through the inclined groove design, further improving the clamping effect on the parts and preventing the parts from shifting.
[0021] Working principle: When using this utility model, the mounting plate 2 is first installed on the linear motor or other moving mechanism of the robotic arm or gantry milling machine through the mounting holes, so as to drive the entire device to move in the overall position. The parts to be spliced are placed between the clamping plates 14. The hydraulic cylinder extends and retracts to drive the center plate 9 to descend to a suitable height. Then, the two first electric push rods push the vertical block in opposite directions, driving the T-shaped plate to move. The first rack 6 meshes with the first gear to make the two T-shaped plates on both sides move synchronously in opposite directions. The long sliding block 13 slides along the guide block 7, reducing the size of the two intersections. The staggered spacing between the clamping plates 14, along with the inclined grooves, clamps and fixes the components. Then, the drive motor is started to rotate the drive gear, which meshes with the second rack to move the connecting frame 10 along the first slide groove, adjusting the position of the component to be picked up. The second electric push rod pushes the push plate 11, causing the slider to slide along the second slide groove, adjusting the position of the suction cup 12 and aligning it with the component. After the suction cup 12 adsorbs the component, the component is picked up and transferred to the splicing area, completing the automatic splicing of multiple parts of the plush doll. At this point, the device is in use.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
