Abstract
Description
Technical Field
[0001] This utility model belongs to the field of measurement technology, specifically a glass volume resistivity measuring device. Background Technology
[0002] The principle of glass volume resistivity is based on Ohm's law and the measurement of electric field strength. Volume resistivity (ρ) is defined as the resistance value per unit volume of a material, used to describe the material's ability to impede current. Its defining formula is ρ = R × A / L, where ρ is the volume resistivity, R is the resistance value of the material sample, A is the cross-sectional area of the sample, and L is the length of the sample. In glass volume resistivity testing, both the electrode and the glass are rigid materials. The flatness of the glass itself can directly lead to incomplete contact between the glass and the electrode. Therefore, the cross-sectional area A used in the calculation will be inaccurate, resulting in deviations in the test data. Summary of the Invention
[0003] To address the technical problem of test data deviation caused by incomplete contact between the glass and the electrode in the prior art, this application proposes a glass volume resistivity measuring device, which solves the above-mentioned technical problem.
[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] This utility model provides a glass volume resistivity measuring device, comprising: two sets of electrodes, each set of electrodes having a flexible conductor disposed on the surface of the glass where it is in contact; during measurement, the first set of electrodes is first disposed at the bottom to support the glass to be measured, and then the second set of electrodes is disposed at the top of the glass for detection; and a flattening module, the flattening module including a pressure roller that moves in the horizontal direction; during measurement, the pressure roller first moves at the top of the glass to completely contact the flexible conductor of the first set of electrodes at the bottom of the glass with the bottom surface of the glass, and then the pressure roller moves at the top of the second set of electrodes to completely contact the flexible conductor of the second set of electrodes at the top of the glass with the top surface of the glass.
[0006] Furthermore, the flattening module also includes: a frame, which is disposed around the electrode; and a belt assembly, which includes a pulley and a belt body, the pulley being mounted on the frame, the belt body being disposed around the electrode and spanning the electrode, a bearing seat being fixed on the belt body, and the pressure roller being rotatably mounted on the bearing seat.
[0007] Furthermore, the frame includes four vertical rods arranged around the electrodes, each vertical rod having a vertical guide groove. The pulley is fitted inside the guide groove. Additionally, each vertical rod is equipped with a detachable positioning ring, which is arranged at the bottom of the pulley to position the pulley at a corresponding height.
[0008] Furthermore, the flexible conductor is conductive rubber.
[0009] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:
[0010] The glass volume resistivity measuring device of this invention uses a soft conductor as an auxiliary electrode between the electrode and the glass to be tested. The soft contact makes the glass to be tested and the soft conductor fit more tightly. At the same time, the pressure roller of the flattening module flattens and removes air bubbles between the glass and the soft conductor, making the cross-sectional area more accurate, thereby ensuring more accurate data testing.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use.

[0015] like Figure 1-2As shown, this utility model provides a glass volume resistivity measuring device, including two sets of electrodes 1 and a flattening module 3. Each set of electrodes 1 has a flexible conductor 11 disposed on the surface that is in contact with the glass 2. During measurement, the first set of electrodes 1 is first disposed at the bottom to support the glass 2 to be measured, and then the second set of electrodes 1 is disposed at the top of the glass 2 for detection. The flattening module 3 includes a pressure roller 31 that moves in the horizontal direction. During measurement, the pressure roller 31 first moves at the top of the glass 2 to completely contact the flexible conductor 11 of the first set of electrodes 1 at the bottom of the glass 2 with the bottom surface of the glass 2, and then the pressure roller 31 moves at the top of the second set of electrodes 1 to completely contact the flexible conductor 11 of the second set of electrodes 1 at the top of the glass 2 with the top surface of the glass 2.
[0016] In one specific embodiment of this utility model, the flattening module 3 further includes a frame 32 and a belt assembly 33. The frame 32 is disposed around the electrode 1. The belt assembly 33 includes a pulley 34 and a belt body 35. The pulley 34 is mounted on the frame 32. The belt body 35 is disposed around the electrode 1 and spans the electrode 1. A bearing seat 36 is fixed on the belt body 35. The pressure roller 31 is rotatably mounted on the bearing seat 36.
[0017] Furthermore, the frame 32 includes four vertical rods 321 arranged around the electrode 1. Vertical guide grooves 322 are formed on the vertical rods 321, and pulleys 34 are fitted within the guide grooves 322. Additionally, detachable positioning rings 37 are also provided on the vertical rods 321, positioned at the bottom of the pulleys 34 to position them at corresponding heights. The height of the pressure roller 31 can be adjusted by changing the height of the pulleys 34 within the guide grooves 322 according to the thickness of the glass 2 being tested, ensuring full contact between the pressure roller 31 and the contact surface and guaranteeing effective air bubble removal.
[0018] In one specific embodiment of this utility model, the pulley 34 can be an elastic element, such as a rubber band, which is sleeved on the vertical rod 321 by its own contraction elasticity.
[0019] In one specific embodiment of this utility model, the flexible conductor 11 is conductive rubber.
