[0002] In the electronics manufacturing industry, conductive adhesive strips (commonly known as zebra strips) are a crucial connecting component, used to effectively connect the display screens and circuit boards of electronic devices such as LCD monitors, game consoles, phones, and digital watches. These strips typically consist of alternating layers of conductive and insulating silicone, formed through a vulcanization process.

[0003] While the design of conductive rubber strips ensures reliable conductivity under normal operating conditions, in practice, they may be stretched or otherwise deformed by external forces. This deformation can affect their conductivity, especially when stretched. However, existing testing techniques typically only test the performance of conductive rubber strips in their undeformed state, ignoring potential performance changes after deformation. This leads to certain technical flaws and limitations. Utility Model Content

The resistance tester 2 is provided with a terminal 3 and a terminal 4. The terminal 3 and the terminal 4 are respectively arranged on the clamping jaws of the cylinder clamp 1 and the clamping jaws of the cylinder clamp 2, and the terminal 3 contacts the left side of the conductive rubber strip and the terminal 4 contacts the right side of the conductive rubber strip.

[0008] The beneficial effects of the utility model are:

The device includes two cylinder jaws (cylinder jaw 1 and cylinder jaw 2), which respectively clamp the two ends of the conductive rubber strip. Driven by two linear modules (linear module 1 and linear module 2), the two jaws can move in opposite directions, thereby applying a tensile force to the conductive rubber strip. Terminals (terminal 3 and terminal 4) are respectively installed on the cylinder jaws. They contact the left and right sides of the conductive rubber strip to test the resistance on both sides of the conductive rubber strip during the stretching process or in the unstretched state.

[0010] 2) In addition, the device is also equipped with a resistance test component 1, which can perform resistance tests on the top and bottom, front and back surfaces of the conductive rubber strip, ensuring that the conductive performance of all six surfaces can be comprehensively and accurately evaluated when the conductive rubber strip is deformed or not. This comprehensive testing method significantly improves the testing efficiency and reliability of the conductive rubber strip, providing a more accurate quality control method for the electronics manufacturing industry.

[0011] On the basis of the above technical solution, the present invention can also be improved as follows.

[0012] Furthermore, the resistance testing component 1 includes a vertical pole, an annular tube sleeve, a rotating ring, an elastic telescopic rod 1, and an elastic telescopic rod 2 arranged opposite to the elastic telescopic rod 1, and the vertical pole is located between the cylinder clamp 1 and the cylinder clamp 2.

[0018] When the rotating ring is driven to rotate so that the first elastic telescopic rod and the second elastic telescopic rod are in the horizontal state, the first wiring terminal and the second wiring terminal are pushed by their own elastic forces to displace along the radial direction of the annular tube sleeve, and then can simultaneously and synchronously contact the front and rear surfaces of the conductive rubber strip.

[0019] Furthermore, a slide rail is provided at the bottom of the vertical rod, and the bottom of the vertical rod slides on the slide rail along the axial direction of the annular tube sleeve.

[0020] The beneficial effect of adopting the above further scheme is that through the sliding of the vertical rod on the slide rail along the axial direction of the annular tube sleeve, the position can be finely adjusted, and the positions of the first wiring terminal and the second wiring terminal on the surface of the conductive rubber strip can be changed, so as to test the conductive performance of different segments of the upper, lower, front and rear four surfaces of the conductive rubber strip, and the conductive performance of each area of the conductive rubber strip can be evaluated more accurately, ensuring the comprehensiveness and accuracy of the test results.

[0026] The principles and features of the present utility model will be described below with reference to the attached drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0027] In the field of electronic manufacturing, a conductive rubber strip (commonly known as a zebra rubber strip) is an important connecting component used to effectively connect the display screen and the circuit board of electronic devices such as liquid crystal displays, game consoles, telephones, and electronic watches. The conductive rubber strip is usually composed of alternately arranged conductive silicone and insulating silicone layers and is formed by a vulcanization process.

[0028] Although the design of the conductive rubber strip ensures its conductive reliability under normal use conditions, in actual applications, the conductive rubber strip may be stretched or deformed in other forms due to external forces. Such deformation may affect its conductive performance, especially in the stretched state. However, after searching the existing test technologies with Chinese patent publication numbers: CN217084780U and CN212779291U, they usually only test the performance of the conductive rubber strip in the undeformed state and ignore the possible performance changes after deformation. Therefore, there are certain technical defects and limitations. In response to this, the inventor of the present utility model has proposed a conductive rubber strip testing device to solve the above problems.

[0029] The present utility model provides the following preferred embodiments

[0030] As Figure 1 、 Figure 2 and Figure 3 shown, a conductive rubber strip testing device includes a conductive rubber strip to be tested. The conductive rubber strip includes an upper surface, a lower surface, a left surface, a right surface, a bottom surface, a front surface, and a rear surface. It further includes:

[0031] The first resistance test component 10 is used to test the resistance on the upper, lower, front, and rear surfaces of the conductive rubber strip;

[0032] The second resistance test component 200 is used to test the resistance between the left and right surfaces of the conductive rubber strip. Among them, the first resistance test component 10 includes a first clamping member 210, a second clamping member 220, and a second resistance tester. The first clamping member 210 and the second clamping member 220 respectively clamp the two ends of the conductive rubber strip to suspend the conductive rubber strip in the air. The first clamping member 210 includes a first bracket 211, a first pneumatic gripper 212, and a first linear module 213. The first bracket 211 is located on one side of the vertical rod 101. The first linear module 213 is fixed on the first bracket 211. The first pneumatic gripper 212 is fixed on the moving end of the first linear module 213. The second clamping member 220 includes a second bracket 221, a second pneumatic gripper 222, and a second linear module 223. The second bracket 221 is located on the other side of the vertical rod 101. The second linear module 223 is fixed on the second bracket 221. The second pneumatic gripper 222 is fixed on the moving end of the second linear module 223. The second resistance tester is provided with a third wiring terminal 230 and a fourth wiring terminal 240. The third wiring terminal 230 and the fourth wiring terminal 240 are respectively arranged on the jaws of the first pneumatic gripper 212 and the jaws of the second pneumatic gripper 222, and the third wiring terminal 230 contacts the left surface of the conductive rubber strip and the fourth wiring terminal 240 contacts the right surface of the conductive rubber strip;

[0033] This test device can simulate the tensile deformation that the conductive rubber strip may encounter during actual use, so as to detect its conductive performance in this state. The device includes two pneumatic grippers (the first pneumatic gripper 212 and the second pneumatic gripper 222), which respectively clamp the two ends of the conductive rubber strip. Driven by two linear modules (the first linear module 213 and the second linear module 223), the two grippers can move in opposite directions, so as to apply a tensile force to the conductive rubber strip. And wiring terminals (the third wiring terminal 230 and the fourth wiring terminal 240) are respectively installed on the pneumatic grippers, and they contact the left and right sides of the conductive rubber strip, so as to test the resistance on both sides of the conductive rubber strip during the stretching process or in the non-stretched state;

[0034] In addition, this device is also equipped with the first resistance test component 10, which can test the resistance of all surfaces (upper, lower, front, and rear) of the conductive rubber strip to ensure that the conductive performance of its six surfaces can be comprehensively and accurately evaluated in the state where the conductive rubber strip is deformed or not deformed. The all-round test method significantly improves the test efficiency and reliability of the conductive rubber strip, providing a more accurate quality control means for the electronic manufacturing industry.

[0035] In this embodiment, as Figure 1 , Figure 2 andFigure 3 As shown, the resistance test assembly 10 includes a vertical pole 101, an annular tube sleeve 102, a rotating ring 103, an elastic telescopic rod 104, and an elastic telescopic rod 2 105 arranged opposite to the elastic telescopic rod 104. The vertical pole 101 is located between the cylinder clamp 1 212 and the cylinder clamp 2 222. The top of the vertical pole 101 extends below the conductive rubber strip, and the annular tube sleeve 102 is fixed to the top of the vertical pole 101 and is sleeved on the outside of the conductive rubber strip. The rotating ring 103 is coaxial with the annular tube sleeve 102 and The first elastic telescopic rod 104 and the second elastic telescopic rod 105 are respectively fixed to the inner side wall of the rotating ring 103 along the radial direction of the annular sleeve 102. The resistance test assembly 10 also includes a resistance tester 1, which is provided with a first wiring terminal 106 and a second wiring terminal 107. The first wiring terminal 106 and the second wiring terminal 107 are respectively arranged at one end of the first elastic telescopic rod 104 and the second elastic telescopic rod 105.

[0036] By arranging the annular tube sleeve 102 outside the conductive rubber strip, and disposing opposing elastic telescopic rods 104 and 105 along the side wall of the rotating ring 103, and by arranging the elastic telescopic rods 104 and 105 along the radial direction of the annular tube sleeve 102, the elastic preload force is transmitted along the radial direction of the annular tube sleeve 102. This ensures that the first and second connection terminals 106 and 107 on the elastic telescopic rods 104 and 105 can simultaneously contact the top, bottom, front, and rear surfaces of the conductive rubber strip.

[0037] When the elastic telescopic rod 104 and the elastic telescopic rod 2 105 are in a vertically upright state, the elastic force of the elastic rod 104 and the elastic telescopic rod 2 105 push the connecting terminal 106 and the connecting terminal 2 107 to move along the radial direction of the annular sleeve 102, and can simultaneously contact the upper and lower surfaces of the conductive rubber strip.

[0038] When the elastic telescopic rod 104 and the elastic telescopic rod 2 105 are in a vertical state, their own elastic force pushes the connecting terminal 106 and the connecting terminal 2 107 to move along the radial direction of the annular sleeve 102, and can simultaneously contact the upper and lower surfaces of the conductive rubber strip.

[0039] In this embodiment, Figure 1 、 Figure 2 and Figure 3As shown in the figure, a slide rail 300 is provided at the bottom of the vertical rod 101, and the bottom of the vertical rod 101 slides on the slide rail 300 along the axial direction of the annular pipe sleeve 102. By sliding the vertical rod 101 on the slide rail 300 along the axial direction of the annular pipe sleeve 102, fine adjustment of the position can be achieved, and the positions of the first terminal 106 and the second terminal 107 on the surface of the conductive rubber strip can be changed, so as to conduct conductivity tests on different segments of the four upper, lower, front and back surfaces of the conductive rubber strip, and the conductivity of each area of the conductive rubber strip can be evaluated more accurately, ensuring the comprehensiveness and accuracy of the test results.

[0040] The specific working process of the present utility model is as follows:

[0041] (1) Conductivity test of the conductive rubber strip in the non-stretched state

[0042] First of all, use the first cylinder jaw 212 and the second cylinder jaw 222 to clamp the two ends of the conductive rubber strip respectively, and the third terminal 230 and the fourth terminal 240 are respectively installed on the jaws, and they are in contact with the left and right sides of the conductive rubber strip to test the resistance of both sides of the conductive rubber strip;

[0043] Secondly, by arranging the annular pipe sleeve 102 outside the conductive rubber strip, and arranging the opposite first elastic telescopic rod 104 and the second elastic telescopic rod 105 along the side wall inside the rotating ring 103, using the function of the first elastic telescopic rod 104 and the second elastic telescopic rod 105 arranged along the radial direction of the annular pipe sleeve 102, when the first elastic telescopic rod 104 and the second elastic telescopic rod 105 are in the vertical state, through their own elastic force, the first terminal 106 and the second terminal 106 are pushed to displace along the radial direction of the annular pipe sleeve 102, and can simultaneously and synchronously contact the upper and lower surfaces of the conductive rubber strip to test the resistance of the upper and lower surfaces of the conductive rubber strip;

[0044] Finally, drive the rotating ring 103 to rotate so that the first elastic telescopic rod 104 and the second elastic telescopic rod 105 are in the horizontal state, and through their own elastic force, the first terminal 106 and the second terminal 107 are pushed to displace along the radial direction of the annular pipe sleeve 102, then the front and back surfaces of the conductive rubber strip can be simultaneously and synchronously contacted to test the resistance of the front and back surfaces of the conductive rubber strip.

[0045] (2) Conductivity test of the conductive rubber strip in the stretched state

[0046] First, the two ends of the conductive rubber strip are clamped using cylinder jaw 1 212 and cylinder jaw 2 222, respectively. Terminals 3 230 and 4 240 are mounted on the jaws, respectively, contacting the left and right sides of the conductive rubber strip. At this point, the two linear modules (linear module 1 213 and linear module 2 223) are driven to move the two jaws in opposite directions, thereby applying a tensile force to the conductive rubber strip, stretching it and deforming its outer side. Terminals 3 230 and 4 240 can then be used to perform resistance tests on the left and right sides of the deformed conductive rubber strip.

[0047] Similarly, even when the conductive rubber strip is deformed, the annular tube sleeve 102 is still sleeved on the outside of the conductive rubber strip. Utilizing the function of the elastic telescopic rod 104 and the elastic telescopic rod 105 being arranged along the radial direction of the annular tube sleeve 102, when the elastic telescopic rod 104 and the elastic telescopic rod 105 are in a longitudinally upright position, their own elastic force pushes the first terminal 106 and the second terminal 107 to continue to move along the radial direction of the annular tube sleeve 102, and can simultaneously contact the upper and lower surfaces of the conductive rubber strip, thereby testing the resistance of the upper and lower surfaces of the deformed conductive rubber strip.

[0048] When the rotating ring 103 is driven to rotate so that the elastic telescopic rod 1 104 and the elastic telescopic rod 2 105 are in a horizontal state, the elastic force of the rotating ring 103 pushes the connecting terminal 106 and the connecting terminal 2 107 to move in the radial direction of the annular sleeve 102, and the front and rear surfaces of the conductive rubber strip can be contacted simultaneously to test the resistance of the front and rear surfaces of the deformed conductive rubber strip.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
