It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention. In addition, the technical features of the embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
Fig. 1 is a schematic structural view of a resistance measurement device for a conductive adhesive tape in a shielding cover according to an embodiment of the present invention, and as shown in fig. 1, the resistance measurement device includes a support assembly 1, a counterweight assembly 2, and a test assembly 3.
The support assembly 1 includes a base plate 11, a vertical shaft 12, and a horizontal shaft 13, the vertical shaft 12 is arranged perpendicular to the base plate 11, one end of the vertical shaft 12 is slidably inserted on the base plate 11, the horizontal shaft 13 is parallel to the base plate 11, one end of the horizontal shaft 13 is slidably inserted on the vertical shaft 12, a sliding direction of the horizontal shaft 13 is perpendicular to a sliding direction of the vertical shaft 12, and a bar-shaped hole 131 extending axially along the horizontal shaft 13 is provided in the horizontal shaft 13.
The counterweight assembly 2 includes a connecting shaft 21, a counterweight 22 and an insulating base 23, the connecting shaft 21 includes a first shaft lever 211 and a second shaft lever 212 which are arranged perpendicular to the bottom plate 11, the first shaft lever 211 is movably inserted in the bar hole 131 (the first shaft lever 211 can rotate and slide in the bar hole 131), the axial length of the first shaft lever 211 is greater than the depth of the bar hole 131 in the direction perpendicular to the bottom plate 11, one end of the first shaft lever 211 is detachably connected with one end of the counterweight 22, the other end of the first shaft lever 211 is coaxially connected with one end of the second shaft lever 212, and the other end of the second shaft lever 212 is connected with the insulating base 23.
The test assembly 3 includes an ohmic resistance meter 31 and two electrodes 32 electrically connected to two terminals of the ohmic resistance meter 31, the two electrodes 32 being movably arranged on the insulating base 23 to adjust the interval between the two electrodes 32, each electrode 32 protruding from the insulating base 23 toward one end of the base plate 11.
For a resistance measuring apparatus for a conductive adhesive tape in a shield cover provided in an embodiment of the present invention, when measuring the resistance of the conductive adhesive tape 200 on the shield cover 100, first, the shield cover 100 is placed on the bottom plate 11 (see fig. 2). Then, according to the type (material or size) of the conductive adhesive tape 200, a balancing weight 22 with proper weight is selected, and the interval between the two electrodes 32 on the insulating base 23 is adjusted to ensure that the interval between the two subsequent detection points is kept consistent. Then, the vertical shaft 12 is slid, and the vertical shaft 12 and the insulating holder 23 are adjusted to appropriate positions in the Y-axis direction. Next, the first shaft lever 211 is slid on the transverse shaft 13, and the insulating base 23 is adjusted to a proper position in the X-axis direction, so that the insulating base 23 moves above the conductive adhesive tape 200 to be measured. Then, the first shaft 211 is rotated, so as to drive the two electrodes 32 of the insulating base 23 to rotate, so that the connecting direction of the two electrodes 32 is consistent with the direction of the conductive adhesive tape 200. Finally, by sliding the transverse shaft 13, the insulating base 23 is lifted in the Z-axis direction, so that the two electrodes 32 are pressed against both sides of the conductive adhesive tape 200 on the basis of the weight 22 (see fig. 3). On this basis, an ohmic resistance meter 31 is started, and current flows into a closed loop formed by the two electrodes 32 and the conductive adhesive tape 200, so that resistance measurement is realized. In addition, when the subsequent products of the same type are measured, the steps are repeated, the same pressure can be always applied, and the distance between the two detection points needs to be kept consistent.
Further, when frequent resistance testing is required for different types of products, it is sufficient to replace the weight 22 with different masses and adjust the spacing between the two electrodes 32.
That is, the resistance measuring device provided by the invention not only can realize the detection of the same type of products and avoid the problem of test failure caused by large fluctuation of test results, but also can realize the detection of different types of products, thereby greatly increasing the application range of the resistance measuring device and ensuring the reliability of the test results.
It should be noted that, because the axial length of the first shaft lever 211 is greater than the depth of the strip-shaped hole 131 in the vertical direction, when the electrode 32 is crimped on the conductive adhesive tape 200, the balancing weights 22 and the transverse shafts 13 are arranged at intervals (see fig. 3), and at this time, the transverse shafts 13 have no supporting force on the balancing weights 22, so that interference of the transverse shafts 13 on the balancing weights in the measurement process is avoided, and the same pressure is ensured to be applied in the vertical direction.
Fig. 4 is an exploded view of a counterweight assembly according to an embodiment of the invention, and as shown in fig. 4, the insulating base 23 includes a first base 231 and a second base 232, and two electrodes 32 are movably disposed on the first base 231, and the first base 231 and the second base 232 are detachably connected together to sandwich the two electrodes 32.
