[0029] EMBODIMENT

[0030] As Figure 1The processing device of the conductive rod of the optimal embodiment is shown, which mainly comprises: a paying-off mechanism 1, a sizing mechanism 3, a shaping mechanism 6, a drying mechanism 7, and a shearing mechanism, the paying-off mechanism 1 is arranged upstream of the sizing mechanism 3, the paying-off mechanism 1 is used to output the wire 2 to the sizing mechanism 3, the wire 2 in this scheme is a conductive fiber, the wire 2 in a roll is paid off through the paying-off mechanism 1, and the paying-off speed can be adaptively matched according to the processing speed of the conductive rod. The sizing mechanism 3 comprises a sizing container, the sizing container in the sizing mechanism 3 is filled with sizing agent, the sizing agent comprises but is not limited to resin or curing agent and other bake-curable reagents, the wire 2 to be processed penetrates through the sizing mechanism 3 and is immersed in the sizing container, when the wire 2 is driven, the sizing agent will infiltrate into the wire 2, the sizing mechanism 3 is also provided with a wire laying roller 4, the number of the wire laying roller 4 in this embodiment is 3, the three wire laying rollers 4 are arranged in parallel in the sizing mechanism 3, are distributed in a staggered manner and can rotate flexibly, the wire 2 is sequentially wound on the wire laying roller 4, the staggered distribution of the wire laying roller 4 can make the wire 2 become flat and loose after passing through the wire laying roller 4, which helps the sizing agent to better infiltrate into the surface and inside of the wire 2. After the wire 2 is infiltrated by the sizing agent, it continues to be driven to the shaping mechanism 6, the shaping mechanism 6 is specifically a shaping die, and the shaping die is provided with a shaping hole, the shaping die is used for shaping the sized wire 2, the shaping die is made of a wear-resistant smooth material including but not limited to ceramic, alumina, zirconia, etc., the size specification of the shaping die can be selected according to actual processing needs, for example, in order to process the 24k nickel-plated carbon wire 2 into a regular cylindrical conductive rod, a shaping die with a hole diameter of 1.9mm and a material of zirconia can be used; for example, in order to process the 12k nickel-plated carbon wire 2 into a regular cylindrical conductive rod, a shaping die with a hole diameter of 1.2mm and a material of zirconia can be used. After the wire 2 is shaped by the shaping mechanism 6, it continues to be driven to the drying mechanism 7, the drying mechanism 7 is provided with a heat source 8, the heat source 8 provides a heat source and performs drying treatment on the wire 2 entering the drying mechanism 7, and after the drying treatment, the wire 2 is cured and has a certain hardness, and the shape and size of the conductive rod can meet the processing needs, which is convenient for subsequent processing. At this time, the wire 2 is called a conductive rod, and the finally formed conductive rod can well meet the needs of subsequent automatic mechanical assembly, and is sheared by the shearing mechanism, which is convenient for subsequent transportation and storage.

[0031] Further, a guide roller 5 is arranged between the sizing mechanism 3 and the shaping mechanism 6, the guide roller 5 guides the wire 2 infiltrated with the sizing agent, so that the wire 2 can be smoothly driven to the shaping mechanism 6 for shaping.

[0032] In order to prevent the yarn 2 from being deformed and affecting the shape of the conductive rod, it is necessary to set two limiting molds 9 in the interior of the drying mechanism 7. The limiting molds 9 are arranged in sequence along the running direction of the yarn 2, and the limiting molds 9 are provided with limiting holes through which the yarn 2 passes. The radial size and shape of the limiting holes are the same as the radial size and shape of the yarn 2. The limiting molds 9 limit the position of the yarn 2 and prevent the yarn 2 from being deformed before drying and curing, which further ensures the processing quality of the conductive rod.

[0033] The processing device of the conductive rod of the embodiment further comprises a driving mechanism 11. The driving mechanism 11 specifically comprises a driving roller and a transmission roller. The driving roller and the transmission roller rotate and clamp the object to generate friction force, thereby moving the object. The driving mechanism 11 is arranged between the drying mechanism 7 and the shearing mechanism, and the driving roller and the transmission roller are arranged on both sides of the conductive rod with a certain hardness. The driving roller and the transmission roller have a gap that is matched with the diameter of the conductive rod, and the gap can be adjusted to prevent the conductive rod from being damaged by the driving roller and the transmission roller.

The pneumatic shear 13 and the sensor 14 are arranged in sequence along the axis of the conductive rod, and the pneumatic shear 13 and the sensor 14 have a given distance therebetween. That is, the conductive rod formed by the drying mechanism 7 is transmitted to the shearing platform 12, and the distance between the pneumatic shear 13 and the sensor 14 at this time is set by the user. The set distance is not limited here. When the conductive rod passes through the pneumatic shear 13 and is transmitted to the position of the sensor 14, the pneumatic shear 13 shears, and finally the conductive rod with a required length is formed.

[0035] Further, a limiting part 10 is arranged between the drying mechanism 7 and the shearing mechanism. The limiting part 10 guides the conductive rod after drying and curing, and prevents the conductive rod after drying from deviating during transmission.

[0036] Further, the embodiment further comprises a collecting box 15, which is arranged below the shearing mechanism, i.e. below the shearing platform 12, and the upper end surface of the shearing platform 12 has an angle of 30° with respect to the horizontal plane, i.e. the upper end surface of the shearing platform 12 is rotated by 30° around the axis of the conductive rod transmitted by the transmission mechanism. After the conductive rod is sheared by the shearing mechanism, the conductive rod will roll along the upper end surface of the shearing platform 12 and fall into the collecting box 15 below, so as to finally realize storage and transportation of the conductive rod.
