Detailed Implementation

[0021] Example 1

[0022] like Figures 1-3 As shown in the figure, the copper-clad steel conductivity testing fixture proposed in this embodiment includes a frame 1, a moving testing device, and two guide rails 11.

[0023] The mobile testing device includes a transmission belt 2, a power assembly for driving the transmission belt 2, and a resistance testing mechanism mounted on the outer periphery of the transmission belt 2. The power assembly includes a servo motor 15 and two transmission rollers 3, both of which are rotatably mounted on a frame 1. The transmission belt 2 is sleeved on the two transmission rollers 3. The servo motor 15 is mounted on the frame 1, and its output shaft is connected to the rotating shaft of the transmission rollers 3. One or more resistance testing mechanisms are provided. Each resistance testing mechanism includes a resistor 4 and two sets of clamping assemblies. The resistor 4 is mounted on the outer periphery of the transmission belt 2, and each set of clamping assemblies... It includes a rotating bracket 5, a spring 8, and two clamping plates 6. The rotating bracket 5 is connected to the outer surface of the transmission belt 2. The two clamping plates 6 are arranged in an "X" shape and are rotatably mounted on the rotating bracket 5. A connecting rod 9 is connected to the clamping plate 6, and a ball bearing 10 is installed on the connecting rod 9. The ball bearing 10 contacts the guide rail 11. Compared with the end of the clamping plate 6 sliding on the guide rail 11, the friction it experiences is less. A conductive sheet 7 is installed on the inner side of the clamping plate 6. The conductive sheet 7 is electrically connected to the resistor 4. The ends of the two clamping plates 6 away from the conductive sheet 7 are connected by the spring 8.

[0024] Two guide rails 11 are symmetrically arranged below the transmission belt 2. The guide rails 11 are connected to the frame 1, and the ends of the two guide rails 11 are provided with wedge-shaped structures.

[0025] Specifically, when testing the conductivity of copper-clad steel material, the copper-clad steel wire is pulled and moved at a constant speed below the transmission belt 2. The transmission belt 2 is driven by a power component, and the movement of the transmission belt 2 drives the resistance testing mechanism mounted on its surface to move. When both clamping plates 6 are positioned in the wedge-shaped area of ​​the two guide rails 11, as the ends of the clamping plates 6 move and contact the wedge-shaped parts, the two clamping plates 6 are forced to rotate synchronously, thereby realizing the automatic clamping of the copper-clad steel wire. At this time, the conductive sheet 7 is in contact with the copper-clad steel wire. When the copper-clad steel wire is in contact with both conductive sheets 7, the resistance meter 4 begins to perform local resistance testing on the copper-clad steel wire placed between the two sets of clamping components. The resistance value after detection and processing can be converted into conductivity. It should be noted that the resistance meter 4 is connected to the controller signal for analyzing the measured data. The controller is a PLC controller or a microprocessor controller.

[0026] Example 2

[0027] like Figure 3As shown in the figure, the copper-clad steel conductivity testing fixture proposed in this embodiment has two moving testing mechanisms compared to the first embodiment. The two moving testing mechanisms are arranged side by side. Two guide rails 11 are symmetrically arranged below each of the two moving testing mechanisms. When a single moving testing mechanism is used to test the conductivity of the copper-clad steel wire, there may be blind spots on the copper-clad steel wire, that is, there are areas that are not detected. When the undetected areas on the copper-clad steel wire move to the position below the other moving testing mechanism, the corresponding clamping components clamp the copper-clad steel wire. At this time, the undetected areas are placed between the two clamping components, making the device more comprehensive in testing the copper-clad steel wire.

[0028] A first transmission assembly connects the two mobile testing mechanisms. The first transmission assembly includes a second synchronous belt 17 and two second synchronous pulleys 16. The two second synchronous pulleys 16 are respectively mounted on the rotating shafts of the corresponding side transmission rollers 3. The two second synchronous pulleys 16 are connected by the second synchronous belt 17. Under the transmission action of the first transmission assembly, the power assembly can simultaneously drive the two transmission belts 2 to move synchronously at the same speed.

[0029] Example 3

[0030] like Figure 1 As shown in this embodiment, a copper-clad steel conductivity testing fixture is proposed. Compared to Embodiment 2, in this embodiment, traction mechanisms are installed at both ends of the frame 1. The traction mechanism includes two rollers 12, which are arranged side by side and rotatably mounted on the frame 1. Gears are installed on the shafts of the two rollers 12, and the two gears are meshed together. A second transmission assembly is connected between the shaft of one roller 12 and the shaft of the transmission roller 3 adjacent to it. The second transmission assembly includes a first synchronous belt 14 and two first synchronous pulleys 13. The two first synchronous pulleys 13 are respectively mounted on the shaft of the transmission roller 3 and the shaft of the roller 12. The two first synchronous pulleys 13 are connected by a transmission belt. The first synchronous belt 14 drives the copper-clad steel wire through two rollers 12, which clamp the wire. When the two rollers 12 rotate in opposite directions, the copper-clad steel wire moves at a constant speed, and the belt can be positioned. The second transmission assembly allows the transmission roller 3 to drive the two rollers 12 to rotate, matching the speed of the copper-clad steel wire with the speed of the transmission belt 2. The rollers 12 have an annular groove on their circumference, with a semi-circular cross-section. This structure increases the contact area between the rollers 12 and the copper-clad steel wire, preventing slippage.

[0031] The embodiment of the utility model is described in detail above in combination with the drawings, but the utility model is not limited to this, and various changes can be made within the knowledge range possessed by the person skilled in the art without departing from the purpose of the utility model.
