[0002] In industries such as electronics, electrical and precision machinery, the automatic and efficient conveying of leads is a crucial part of the production process. However, due to the slender and flexible nature of the leads themselves, they are extremely prone to entanglement and stacking during the conveying process, which not only affects production efficiency and product quality, but also increases the need for manual intervention and raises production costs. Even for the lead conveying methods that utilize simple mechanical devices, the following problems exist:

[0003] Entanglement problem: The leads are prone to entanglement due to mutual contact during the conveying process, especially when conveyed over long distances and at high speeds.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is two or more.

[0031] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0032] A lead conveying mechanism includes two conveying racks 11 arranged side by side. At both ends of the facing surfaces of the two conveying racks 11, a conveying driving sprocket 12 and a conveying driven sprocket 13 are respectively rotatably installed. An endless chain 14 is sleeved on and meshed with the conveying driving sprocket 12 and the conveying driven sprocket 13.

[0033] One end of one of the conveying racks 11 is installed with a conveying motor 15. The motor shaft of the conveying motor 15 passes through the conveying rack 11 and is connected to the conveying driving sprocket 12.

[0034] At least one elastic clip 17 is installed on the plate surface of the conveying plate 16 spacedly arranged on the endless chain 14. The elastic clip 17 is used for clamping the lead to be processed.

[0035] Specifically, as Figures 1-5 shown, after the conveying motor 15 is started, the conveying driving sprocket 12 is driven to rotate by the motor shaft of the conveying motor 15, and then the endless chain 14 is driven to move cyclically along the outer surfaces of the conveying driving sprocket 12 and the conveying driven sprocket 13. The conveying plate 16 on the endless chain 14 moves accordingly. The lead to be processed is manually clamped in the elastic clip 17 on the conveying plate 16, so that the lead to be processed is also stably conveyed.

[0036] In summary, the present utility model makes full use of the continuity and stability of the transmission of the endless chain 14, combines with the flexible clamping ability of the elastic clip 17, effectively avoids the mutual entanglement and stacking of the leads, and at the same time realizes the automatic, efficient and orderly conveying of the leads.

[0037] Furthermore, the endless chain 14 includes a plurality of outer connectors 141 and inner connectors 142 connected at intervals;

[0038] The outer connecting member 141 includes a pair of outer flat plates 1411, a pin shaft 1412 and a sleeve 1413, and the inner connecting member 142 includes a pair of inner flat plates 1421; a pair of the inner flat plates 1421 are clamped between two adjacent pairs of the outer flat plates 1411, and two ends of the inner flat plates 1421 are respectively fixedly connected to one end of the adjacent outer flat plates 1411 through the pin shaft 1412, and the pin shaft 1412 is installed between opposite surfaces of the pair of inner flat plates 1421, and the sleeve 1413 is sleeved and rotatably installed on the pin shaft 1412;

[0039] Conveying connection parts 143 are arranged in an extending manner towards each other on the outer flat plates 1411 which are oppositely arranged on the two annular chains 14, the conveying connection parts 143 are perpendicular to the outer flat plates 1411, first conveying connection holes 1430 are formed in the conveying connection parts 143, second conveying connection holes 160 are formed at two ends of the conveying plate 16, and the first conveying connection holes 1430 and the second conveying connection holes 160 are aligned for a conveying fixing piece to pass through and be fixedly connected.

[0040] Specifically, as Figure 4 shown, the annular chain 14 moves cyclically under the drive of the conveying driving sprocket 12 and the conveying driven sprocket 13. The conveying connection parts 143 on the outer flat plates 1411 serve as connection points to fix the conveying plate 16 on the annular chain 14 and move together with the annular chain 14. The design of the pin shaft 1412 and the sleeve 1413 allows the annular chain 14 to have a certain flexibility during the rotation process, reduces friction and wear, and improves the stability and service life of the entire conveying mechanism 1.

[0041] Furthermore, it is noted that the number of the elastic snap fasteners 17 is two, and the two elastic snap fasteners 17 are respectively detachably installed at two ends of the conveying plate 16.

[0042] Furthermore, it is noted that the elastic snap fastener 17 includes a snap fastener fixing body 171 and a pair of elastic clamping arms 172. One ends of the pair of elastic clamping arms 172 are symmetrically arranged on two sides of the snap fastener fixing body 171 and are integrally connected to the snap fastener fixing body 171, and an elastic clamping opening is formed between the other ends of the pair of elastic clamping arms 172;

[0043] A snap fastener fixing through hole 1710 is formed in the middle of the snap fastener fixing body 171, and the snap fastener fixing through hole 1710 and the second conveying connection hole 160 are aligned for a conveying fixing piece to pass through and be fixedly connected.

[0044] Specifically, as Figure 5As shown, the lead to be processed can be clamped between a pair of elastic clamping arms 172 through the elastic clamping opening, and the elastic deformation of the elastic clamping arms 172 is used to clamp and release the lead. When clamping, the elastic clamping arms 172 are forced to shrink inward, the clamping opening becomes smaller, and the lead is firmly clamped; when releasing, the clamping arms return to their original positions, the clamping opening opens, and the lead is free to detach. Therefore, the design of the elastic clamping arms 172 makes the clamping process more flexible and easy to operate, and can also adapt to leads of different diameters and shapes.

[0045] To further illustrate, the pair of elastic clamp arms 172 are arranged in an arc shape, and the vertical cross-section of the elastic clamp buckle 17 is in a U shape. Figure 5 As shown, the arc-shaped elastic clamp arm 172 can better fit the surface of the lead to be processed, increase the stability and firmness of the clamping, and reduce the damage to the lead to be processed.

[0046] To further illustrate, a pair of elastic clamping arms 172 are provided with guide portions 173 extending toward both sides from one end away from the clamp fixing body 171, and the guide portions 173 and the elastic clamping arms 172 are in an arc transition. Figure 5 As shown, the design of the guide portion 173 helps the lead to be processed to smoothly enter the elastic clamping port, reduces the clamping failure caused by misoperation or lead deviation, and improves the accuracy and efficiency of clamping.

[0047] Further explanation, the elastic clamp arm 172 and the guide portion 173 are covered with a rubber protective cover. Specifically, the rubber protective cover is not shown in the figure, which can effectively protect the surface of the lead to be processed from being scratched or worn, and at the same time increase the friction coefficient during the clamping process, making the clamping more stable and reliable. In addition, the elasticity of the rubber can also buffer the impact force during the clamping process to a certain extent, further protecting the integrity of the lead to be processed.

[0048] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementations of the present invention without creative work, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
