Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, and in particular to a conveying positioning mechanism. Background Art

[0002] Conveying equipment plays a vital role in the production process of injection molded parts. Injection molded parts, as a common form of plastic product production, are made by injecting molten plastic material into precision molds, which are then cooled and solidified to form the desired shape. In this process, conveying equipment plays a role far more than simply moving items. They are a key link in ensuring the continuity and efficiency of the production process. They are not only responsible for seamlessly transferring injection molded parts from one production link to the next, but also optimize the entire production process by precisely controlling the conveying rhythm and path, reducing delays and errors caused by human operation.

[0003] However, existing conveying equipment faces some challenges in the process of conveying injection molded parts from the injection molding machine to the coding equipment. In particular, after the injection molded parts have completed the previous process, they need to be accurately grasped by a robotic arm and placed on the conveying equipment connected to the coding equipment. In this process, the repetitive movements of the robotic arm may cause slight deviations in the spacing between the injection molded parts. Although these deviations are small, they are enough to affect the accuracy of the subsequent coding process. The coding process requires extremely high precision to ensure that each injection molded part can be accurately marked, which is crucial for product traceability, brand recognition and quality control.

[0025] Working principle: According to Figure 1 As shown, the driving device 5 starts to drive the mechanical arm 3 to rotate. In the process of transferring the workpiece to the conveying mechanism 1, the first full gear 601, the second full gear 602 and the first convex gear 603 are driven to rotate through the gear plate 4. The first convex gear 603 drives the propulsion gear rod 701 to move. The propulsion gear rod 701 is limited by the first slide bar 702, so that the first return spring 704 is compressed. At the same time, the propulsion gear rod 701 drives the first piston rod 705 to move in the first piston cylinder 706. The hydraulic oil in the second piston cylinder 707 is pumped into the first piston cylinder 706 through the pipeline, so that the second piston rod 708 moves synchronously, thereby synchronously pushing the propulsion gear rod 701 and the auxiliary propulsion rod 709 on both sides of the conveying mechanism 1, so that the adjusting threaded rod 710 and the bonding plate 711 are close to each other to guide the workpiece; The rotating shaft on the second full gear 602 drives the trigger gear rod 801 to work through the chain 604, and similarly compresses the second return spring 804, triggering the gear rod 801 to move toward the conveying mechanism 1, squeezing the contact concave plate 805, so that the contact concave plate 805 moves downward in the concave guide frame 806, and the inclined surface on the bevel gear block 807 contacts the inclined surface of the tooth surface area of ​​the concave guide frame 806, thereby not affecting the downward movement of the contact concave plate 805. However, the right-angled surface on the bevel gear block 807 contacts the right-angled surface of the tooth surface area of ​​the concave guide frame 806, which will limit the upward movement of the contact concave plate 805. When the two workpieces are transmitted by the conveying mechanism 1 and both hit the extrusion block 811, the extrusion block 811 will be squeezed into the second empty groove 812, and the second propulsion spring 813 will be compressed. The extrusion rod 810 that is fitted on both sides of the end of the extrusion block 811 will be partially disengaged from the extrusion, and under the influence of the first propulsion spring 809, partially enter the second empty groove 812, so that the abutment force on the bevel gear block 807 is reduced, and partially enters the first empty groove 808, and is disengaged from the contact with the tooth surface area of ​​the concave guide frame 806, so that it moves upward under the drive of the third return spring 814, so that the workpiece on the conveying mechanism 1 passes through the bottom of the abutting concave plate 805 and continues to be conveyed to the coding device 9. Only when both workpieces contact the extrusion block 811 and the extrusion block 811 enters the second empty groove 812, will the abutting concave plate 805 be disengaged from the concave guide frame 806, so as to achieve the purpose of adjusting the spacing. This is the working principle of the conveying positioning mechanism.
