[0001] The utility model relates to the technical field of testing devices, in particular to a conductivity testing device for conductive sheets. Background Technique

[0002] A sheet refers to a material that has resin (or monomers directly polymerized during processing) as the main component, and additives such as plasticizers, fillers, lubricants, and colorants as auxiliary components, and can be formed by flowing during processing.

[0003] With the development of science and technology, various plastic materials emerge in an endless stream. Due to the extremely high ductility, wear resistance and other characteristics of plastic materials, they are widely used in fields such as wires and electronic products. Among them, the conductivity of plastic materials is also particularly important and needs to be detected for application in corresponding products. Therefore, conductivity testing equipment is required.

[0004] However, when the existing conductivity testing devices are in use, it is not convenient to adjust according to the size of the sheet, resulting in a limited range that can be fixed, poor applicability, and inconvenient for the conductivity testing work of conductive sheets of different sizes. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1-4 shown, the present invention provides a technical solution: including a substrate assembly 1, a testing assembly 3 for testing the conductivity of a conductive sheet is arranged at the front part of the front surface of the substrate assembly 1, and a clamping assembly 2 for clamping the conductive sheet is arranged between the substrate assembly 1 and the testing assembly 3;

[0022] The substrate assembly 1 includes a mounting plate 101, a first driving lead screw 102 and a chute are respectively arranged on both side surfaces of the mounting plate 101, a threaded slider 103 is threadedly sleeved on the first driving lead screw 102, an embedded slider is slidably installed in the chute, a hollow shelf plate 104 is fixedly installed in the middle of the front surface of the mounting plate 101, and a first magnet 105 is fixedly installed at both edge positions on the top surface of the hollow shelf plate 104;

[0023] The clamping assembly 2 includes a round shaft 201, the round shaft 201 is fixedly inserted in the middle of the front surface of the mounting plate 101, two first articulated rods 202 are rotatably sleeved on the shaft body of the round shaft 201, a second articulated rod 206 is rotatably installed at the bottom end of each of the two first articulated rods 202, the middle parts of the two second articulated rods 206 are hinged together, a second magnet 203 is fixedly installed on the back surface of the top end of each of the two first articulated rods 202, a threaded rod 204 is fixedly installed at both front ends of a first articulated rod 202 and a second articulated rod 206, a threaded rod 204 is fixedly installed at the front end of the other first articulated rod 202 and the other second articulated rod 206, and a limit chuck 205 is threadedly sleeved on each threaded rod 204. The plurality of limit chucks 205 can prevent the sheet from detaching from the front surface of the clamping assembly 2.

[0024] In this embodiment, the test component 3 includes a vertical plate 301. A support rod 302 is fixedly installed at each of the two side edges on the back surface of the vertical plate 301. A cylinder 303 is fixedly installed in the middle of the front surface of the vertical plate 301. One end of the piston rod of the cylinder 303 is fixedly installed with a moving plate 304.

[0025] At the same time, a pressing plate 305 is fixedly installed on the back surface of the moving plate 304. A second driving lead screw 306 is arranged on the back surface of the pressing plate 305. Threaded blocks are sleeved on both ends of the second driving lead screw 306. A positive and negative electrode plate 307 is fixedly installed on the back surface of each of the two threaded blocks.

[0026] One end of each of the two support rods 302 is fixedly connected to the surface of a threaded slider 103 and an embedded slider respectively, which can conveniently adjust the position of the test component 3.

[0027] The top surface of the first magnet 105 and the bottom surface of the second magnet 203 are arranged to attract each other with opposite polarities. The clamping component 2 can be in an unfolded state when not clamping the conductive sheet material through the adsorption connection between the first magnet 105 and the second magnet 203.

[0028] During use, the conductive sheet material to be tested can be taken out. After taking it out, it is inserted vertically into the clamping component 2. As the conductive sheet material is inserted, its bottom surface will contact the surfaces of the two bottommost threaded rods 204. After contact, under the action of the conductive sheet material, the two threaded rods 204 will descend. By the descent of the two threaded rods 204, the bottoms of the two second hinge rods 206 will descend. Since the middle parts of the two second hinge rods 206 are hinged together, as the bottoms of the two second hinge rods 206 descend, the bottoms of the two first hinge rods 202 will be driven to descend. Since the middle parts of the two first hinge rods 202 are rotatably sleeved on the round shaft 201, as the bottoms of the two first hinge rods 202 descend, the four threaded rods 204 arranged on both sides will be driven to close, and then the two sides of the sheet material will be clamped by the four threaded rods 204. The two bottommost threaded rods 204 are used to prevent the sheet material from falling, and the hollow support plate 104 is used to support the back surface of the sheet material. During the clamping process, the sheet material can be restricted from detaching from the front surface of the clamping component 2 by a plurality of limit chucks 205.

[0029] At the same time, manually turn the limit chuck 205 according to the thickness of the test sheet material. By turning the limit chuck 205, it can move on the corresponding threaded rod 204, so that the limit chuck 205 can be adjusted to adapt to the thickness of the sheet material.

[0030] After clamping the sheet, the conductivity of the sheet can be tested by controlling the test component 3. Specifically, start the cylinder 303, and the cylinder 303 drives the positive and negative electrodes 307 to contact the surface of the sheet. Then, an external battery is connected. Since the battery is electrically connected to the positive and negative electrodes 307, the battery provides electricity to the positive and negative electrodes 307. Since the positive and negative electrodes 307 are also externally connected to indicator lights, the positive and negative electrodes 307 can contact the conductive material to make the indicator lights flash, thereby testing the conductivity of the conductive sheet. At the same time, the positions of the two positive and negative electrodes 307 can be adjusted by the No. 2 transmission screw 306. Since the threaded screw used in the No. 2 transmission screw 306 is a double-headed threaded screw, the thread rotation directions of the two ends are opposite. Therefore, the two positive and negative electrodes 307 can be controlled by the No. 2 transmission screw 306 to approach or move away from each other, thereby adapting to sheets of different lengths for conductivity testing.

[0031] To summarize, the conductivity testing device for the conductive sheet inserts the conductive sheet vertically into the clamping assembly 2. Under the action of the conductive sheet, the four threaded rods 204 arranged on both sides of the clamping assembly 2 will be retracted, and then the two sides of the sheet are clamped by the four threaded rods 204, and the sheet is prevented from falling by the two threaded rods 204 at the bottom. The back of the sheet is supported by the hollow frame plate 104. During the clamping process, the sheet can be limited from detaching from the front of the clamping assembly 2 by multiple limit clamps 205, so that conductive sheets of different sizes can be clamped conveniently and easily, which is more practical.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
