Description

Technical Field

[0001] This utility model relates to the field of product testing technology, and in particular to a novel pressure-holding test fixture for conductive cloth auxiliary materials. Background Technology

[0002] Conductive cloth is usually made by uniformly depositing a conductive metal layer onto a flexible base fiber (such as polyester, nylon, cotton, etc.) through processes such as electroplating, chemical plating, or vacuum sputtering. The pressure holding test for conductive cloth accessories mainly ensures that the conductive adhesive on the back of the conductive cloth can achieve the expected adhesion under the specified pressure. More important tests are then conducted on peel strength and conductivity or shielding performance.

[0003] The pressure holding test involves placing the conductive cloth auxiliary material on a fixture, applying pressure through a pressurizing device, and holding the pressure for a certain period of time to complete the test. Currently, common pressure holding test fixtures can only achieve the effects of pressurizing and fixing the conductive cloth. However, in batch pressure holding tests of conductive cloth, the conductive cloth will deform to a certain extent after being compressed (the compressed area will be concave downwards, while the edges will extend outwards). This means that the extended parts cannot be fully subjected to pressure, and the compressed area in the middle is more likely to deform and break, resulting in deviations in the test results. At the same time, after being subjected to a certain pressure, the conductive cloth auxiliary material may adhere firmly to the fixture table and cannot be easily removed as a whole. Tearing it from the corners may cause damage or secondary deformation.

[0004] Therefore, it is necessary to provide a new type of pressure-holding test fixture for conductive cloth accessories to solve the above-mentioned technical problems. Utility Model Content

[0026] Four graduated scales 16 are embedded and fixedly mounted on the bottom inner wall of the enclosing bin 11, the positions of the four graduated scales 16 respectively correspond to the four vertical plates 14, in conjunction with the figure

[0031] The working principle of the novel conductive cloth auxiliary material pressure holding test fixture provided by this utility model is as follows:

[0032] In the pressure holding test of conductive cloth accessories, the operator first selects a pressure plate 8 of the same specification according to the size of the conductive cloth accessory to be tested, and fixes it to the fixing base 6 with fixing bolts 9. Then, the position of the four vertical plates 14 is adjusted according to the size of the conductive cloth accessory. Rotating the four rotating wheels will drive the threaded cylinder 12 to rotate, thereby driving the threaded rod 13 to move laterally, thus adjusting the position of the vertical plates 14. The adjustment is made according to the display of the vertical plates 14 on the scale 16. After adjusting to the appropriate position, if the four vertical plates 14 cannot form a closed state, the insertion plate 15 is spliced ​​on the vertical plates 14. By extending the length of the vertical plates 14 through the insertion plate 15, the four vertical plates 14 are finally closed (forming a closed state). Figure 3 (The state shown).

[0033] At this point, the staff can place the conductive cloth auxiliary material to be tested on the bottom inner wall of the enclosure 11. After the test is completed, the pressurizing equipment 10 will be started. When the pressurizing equipment 10 is started, the pressure plate 8 will move downward and eventually come into contact with the conductive cloth and gradually begin to apply pressure. At this time, after the conductive cloth is pressed, because there are vertical plates 14 and plug-in plates 15 on all sides, even if the conductive cloth is under pressure, the four sides of the conductive cloth cannot extend to the four sides, so that the conductive cloth is fully and completely pressurized.

[0034] After the pressure is applied, if the conductive cloth is fully adhered to the bottom inner wall of the enclosure 11 and is difficult to separate, the staff can rotate the second rotating wheel. The rotation of the second rotating wheel will drive the drive shaft 21 to rotate, which in turn drives the rotating shaft 20 to rotate under the transmission of the bevel gear group 3. At this time, since the connecting cylinder 18 is limited and cannot rotate with it, it can only move upward under the side effect of the thread of the transmission cylinder 19, which in turn drives the top support block 17 to move upward, ultimately achieving the effect of lifting the conductive cloth auxiliary material.

[0035] Compared with related technologies, the novel conductive cloth auxiliary material pressure holding test fixture provided by this utility model has the following beneficial effects:

[0036] This utility model provides a novel pressure-holding test fixture for conductive cloth accessories. In the pressure-holding test of conductive cloth accessories, by using multiple pressure plates 8 of various specifications and the extension of the vertical plate 14 by the plug-in plate 15, it can meet the test requirements of most specifications. Furthermore, by blocking the conductive cloth around the vertical plate 14 and the plug-in plate 15, the conductive cloth is prevented from deforming under pressure, thus avoiding uneven pressure. At the same time, during the unloading process, the top support block 17 can be moved upward by rotating the drive shaft 21 to assist in the process, effectively protecting the integrity of the test sample. The whole process is not only convenient to operate, but also avoids deformation and damage to the test sample, thereby improving the efficiency and quality of the test.
