Description

Technical Field

[0001] The utility model relates to the technical field of metal piece production and processing, in particular to an automatic classification and receiving device for metal piece bars. Background Art

[0002] In traditional metal bar production, sorting and collecting are often manual operations. Operators must manually inspect the bars and sort them based on characteristics such as size, shape, and surface quality. This process is not only inefficient, but also limited by the operators' speed and physical limitations. Furthermore, it cannot keep pace with modern high-speed production, creating a bottleneck in production efficiency.

[0003] Manual identification of good and defective products is a common traditional method, but this method is susceptible to human influence. Operators need to make subjective judgments based on their experience, and different individuals may have different judgment criteria, resulting in inconsistent recognition results. Fatigue caused by long-term repetitive work further affects recognition accuracy and increases the rate of false positives. Currently, traditional industries manually sort and collect metal parts and bars. Manual identification is poor, inefficient, prone to false positives, and wastes a lot of labor. Traditional processes are relatively cumbersome, waste a lot of time, and have high testing costs. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0027] like Figure 1 As shown, an automatic sorting and receiving device for metal parts and bars includes a mobile platform 1, a lower receiving tray 2, an upper receiving tray 3 and a sorting and transferring mechanism 4. The lower receiving tray 2 is fixedly arranged on the upper side of the mobile platform 1, the upper receiving tray 3 is fixedly arranged on the upper side of the mobile platform 1 and is located above the lower receiving tray 2, and the sorting and transferring mechanism 4 is arranged on the mobile platform 1 and is located on the sides of the lower receiving tray 2 and the upper receiving tray 3.

[0028] like Figure 1 and Figure 2 As shown, the sorting and transferring mechanism 4 includes an upper receiving platform 41 arranged on one side of the upper receiving tray 3, an upper adjustable stopper 42 is rotatably arranged on the outer side of the upper receiving platform 41, and a pull rod cylinder 43 is connected to the upper adjustable stopper 42 to make it rotate. A lower receiving platform 44 is arranged on one side of the lower receiving tray 2 and below the upper receiving platform 41, and a lower adjustable stopper 45 is fixedly arranged on the outer side of the lower receiving platform 44, and openings 4 are respectively provided at the upper and lower corresponding positions of the upper and lower adjustable stops 42 and the lower adjustable stopper 45. 6. A linear guide rail 47 is vertically fixed to the mobile platform 1. A horizontally mounted linear module 48 is slidably mounted on the linear guide rail 47. A fixed fork rod 49 is fixedly mounted on the linear module 48. A movable fork rod 410 is slidably mounted on the linear module 48. The fixed fork rod 49 and the movable fork rod 410 are located at positions corresponding to the opening 46. A stepper motor 411 is mounted on the linear module 48 to drive the movable fork rod 410 to move horizontally. The linear module 48 is connected to a push cylinder 412 to move the movable fork rod 410 on the linear guide rail 47. Fork blocks are fixedly mounted on the upper ends of the fixed fork rod 49 and the movable fork rod 410. A V-shaped fork groove is provided on the upper side of the fork blocks. The upper material receiving platform 41 and the lower material receiving platform 44 are tilted toward the inner sides of the upper material receiving tray 3 and the lower material receiving tray 2, respectively.

[0029] like Figure 1 and 3 As shown, the upper adjustable stop 42 and the lower adjustable stop 45 both include a base plate 421, a fixed plate 422 is fixedly provided at one end of the base plate 421, a long slot 423 is provided at the other end of the base plate 421, an adjustment plate 424 is connected to the base plate 421 through the long slot 423 and a fastener, and the opening 46 is located between the fixed plate 422 and the adjustment plate 424, the base plate 421 of the upper adjustable stop 42 is rotatably connected to the upper material receiving platform 41, and the base plate 421 of the lower adjustable stop 45 is fixedly connected to the lower material receiving platform 44.

[0031] The utility model has reasonable structure, simple operation and high automation, and mainly comprises an electrical control system, an upper and lower material receiving device, a connecting rod hinge material blocking and selecting device, a material receiving and conveying device and a PLC control system.

[0032] After ensuring that the incoming material has been correctly placed on the receiving fork rod, the PLC control system starts. If the product is detected to be good, the PLC controls the pull rod cylinder 43 to push out, and the upper adjustable stopper 42 blocks the product in the upper layer. At this time, the push cylinder 412 only needs to move downward, and the product will enter the upper receiving tray 3 along the upper adjustable stopper 42 and the upper receiving platform 41. If the product is judged to be defective, the pull rod cylinder 43 will be shortened, and the upper adjustable stopper 42 will rotate and move downward, no longer blocking the product in the upper and lower directions. Subsequently, the push cylinder 412 moves downward, and the product will enter the lower receiving position, where it will be blocked by the lower adjustable stopper 45 and slide into the lower receiving tray 2 through the lower receiving platform 44. This process is repeated to achieve continuous automatic classification and collection of materials.

[0033] Driven by a high-precision stepper motor 411, the linear module 48 in this utility model moves the movable fork to accommodate the collection of products of varying lengths. A high-precision linear guide 47 ensures smooth and accurate material transport, while a push cylinder 412 provides the upward and downward motion. The entire system operates efficiently and smoothly. By adjusting the positions of various components, it can accommodate the sorting and collection of products of varying lengths and diameters, achieving fully automated operation and saving labor costs while ensuring stable and accurate collection.

[0034] The preferred embodiments of the present application are described in detail above, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of the present application.
