Description

Technical Field

[0001] The utility model relates to a detection device, in particular to a detection device for the conductivity of a copper rod. Background Art

[0002] Copper rods are the raw material for copper wire production, and conductivity is one of the primary performance criteria for copper rods. Therefore, after copper rods are produced, they must undergo conductivity testing before they can be turned into copper wire. The typical testing method involves running a current through the copper rods and measuring their resistance to derive the resistivity.

[0003] Existing testing equipment places conductive electrodes on both ends of a copper rod to measure its resistance. Once the measurement is complete, the electrodes are removed and then connected to the ends of the next copper rod for testing. This approach results in low testing efficiency. Utility Model Content

[0032] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0033] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention.

[0034] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] Example:

[0036] See also Figure 1 and Figure 2 This embodiment discloses a copper rod conductivity detection device, including a base plate 10, a lever 20, an abutment assembly 30 and a multimeter (not shown in the figure), wherein the lever 20 is rotatably set on the base plate 10, the abutment assembly 30 is fixedly set on the base plate 10, and the multimeter is electrically connected to the abutment assembly 30.

[0037] Specifically, the base plate 10 is made of an insulating material, such as plastic, wood, stone, etc. Two strip grooves 11 are provided on the base plate 10. The two strip grooves 11 are arranged parallel to each other, and the length directions of the two strip grooves 11 are perpendicular to the length direction of the base plate 10. The two strip grooves 11 are respectively close to the two ends of the base plate 10.

[0038] There are two levers 20, one for each of the two strip grooves 11. One end of the lever 20 is pivotally connected to the bottom surface of the base plate 10, and the connection between the lever 20 and the base plate 10 is located in the middle of the strip groove 11. When the lever 20 rotates, there is a gap between the other end of the lever 20 and both ends of the strip groove 11, allowing this end of the lever 20 to pass through the strip groove 11 and be placed above the base plate 10.

[0039] There are two abutment components 30, which are fixedly arranged on both ends of the bottom plate 10, and the two abutment components 30 are respectively close to a strip groove 11. During operation, the two abutment components 30 can respectively abut against the two ends of the copper rod 40 and clamp the copper rod 40 between the two abutment components 30.

[0040] Two electrode terminals of a multimeter are electrically connected to the two abutting components 30 respectively, and the resistance value of the copper rod 40 is measured by the multimeter.

[0041] During operation, the base plate 10 can be installed at a certain inclination angle, and then a number of copper rods 40 that need to be tested are placed on the base plate 10 in sequence. The potential energy of gravity is used to make all the copper rods 40 have a tendency to roll downward. Then, the copper rods 40 are driven one by one to the top of the strip groove 11 by the lever 20 and connected to the two abutment components 30, so that the measurement can be carried out quickly. The two abutment components 30 can be used to tighten the two ends of the copper rod 40 so that the copper rod 40 will not slide down. When the measurement is completed, the lever 20 is rotated to drive the copper rod 40 that has been measured away from the two abutment components 30, and the next copper rod 40 is connected to the two abutment components 30.

[0042] Through this technical solution, the resistance value of the copper rod 40 can be quickly measured.

[0043] In one specific embodiment:

[0044] Two limiting grooves 12 are further provided on the bottom plate 10 . The two limiting grooves 12 are located between the two strip grooves 11 . The two limiting grooves 12 are arranged parallel to each other. The length direction of the two limiting grooves 12 is consistent with the length direction of the two strip grooves 11 .

[0045] The detection device also includes a limit rod 51 and a spring 52. The limit rod 51 is disposed within the limit slot 12. The limit rod 51 is shorter than the limit slot 12, and one limit rod 51 is located in each of the two limit slots 12. One end of the limit rod 51 is pivotally connected to the bottom of the base plate 10, with the connection point between the limit rod 51 and the base plate 10 near the end of the limit slot 12. The other end of the limit rod 51 passes through the limit slot 12 and is positioned above the base plate 10.

[0046] One end of the spring 52 is connected to the bottom surface of the base plate 10 , and the other end of the spring 52 passes through the limiting groove 12 and is fixedly connected to the top end of the limiting rod 51 .

[0047] like Figure 2 As shown, after a copper rod 40 is fixed on the base plate 10 by two abutting assemblies 30 , the limiting rod 51 and the shifting rod 20 are respectively located on both sides of the copper rod 40 .

[0048] As can be seen from the above, the limit rod 51 is mainly used to limit the position of the copper rod 40. After the detection of the copper rod 40 is completed, the lever 20 drives the copper rod 40 to move, and the copper rod 40 presses the limit rod 51 downward, so that the top end of the limit rod 51 rotates and rotates into the limit groove 12. At this time, the copper rod 40 can roll off the bottom plate 10 without obstacles.

[0049] In another specific embodiment:

[0050] The shift lever 20 is arc-shaped. The two shift levers 20 are arranged on a shaft 21. One end of the shaft 21 is dynamically connected to the output shaft of a servo motor (not shown in the figure).

[0051] In addition, if Figure 2 As shown, the end of the shifting rod 20 away from the end thereof that is rotatably connected to the shaft 21 is bent toward the side of the limiting rod 51 .

[0052] In this embodiment, the rotation of the shaft 21 is controlled by a servo motor, and the arc-shaped shifting rod 20 is matched with the cylindrical structure of the copper rod 40 .

[0053] In another specific embodiment:

[0054] The detection device further includes two baffles 60 , wherein the two baffles 60 are arranged parallel to each other at both ends of the bottom plate 10 , forming a channel between the two baffles 60 , and one end of the channel is located on one end of the strip groove 11 .

[0055] Preferably, both ends of the baffle 60 are arc-shaped structures that bend outward.

[0056] A channel is formed by the two baffles 60 so that all copper rods 40 that need to be inspected can move within the channel.

[0057] In another specific embodiment:

[0058] The abutment assembly 30 includes a support plate 31, a connector 32, an L-shaped plate 33, and a compression spring 34. Specifically, the support plate 31 is mounted on one end of the base plate 10 and has a movable hole at its top. The connector 32 is a hemispherical structure that is movably mounted within the movable hole. One side of the connector 32 has a curved surface that abuts the end of the copper rod 40. The connector 32 is electrically connected to the electrodes of the multimeter.

[0059] One end of the L-plate 33 is fixed to the end of the base plate 10 and forms a U-shaped structure with the support plate 31 . A compression spring 34 is provided between the other end of the L-plate 33 and the connector 32 .

[0060] Preferably, the connectors 32 are made of insulating material. A metal sheet is attached to one side of the spherical surface of the connector 32 , and the metal sheet is electrically connected to the electrodes of the multimeter.

[0061] In this embodiment, the connector 32 is movably set on the support plate 31, and the connector 32 is pressed against the connecting plate by the compression spring 34. When the two ends of the copper rod 40 contact the spherical surfaces of the two connectors 32, the connector 32 can move and the copper rod 40 can be smoothly stuck between the two connectors 32.

[0062] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
