Description

Technical Field

[0001] This application relates to the field of strip performance testing technology, and in particular to a mold for strip resistance testing. Background Technology

[0002] In the processing of strip materials, performance testing is an important indicator for determining whether the strip material is qualified.

[0003] There is a type of long strip material that requires resistivity testing after production. Current processing methods typically involve batch production, where multiple strips are produced at once and then sampled for inspection to ensure the pass rate of the resistivity test for that batch. Therefore, in existing technology, workers usually collect several sampled strips, then use a resistance testing instrument to test each strip individually, recording whether each strip passes the test. Finally, the number of passing strips is tallied to determine the pass rate of the entire batch.

[0004] However, in actual use, the above-mentioned testing method requires workers to record whether each strip is qualified after testing it. When there are a large number of strips to be tested, the overall testing efficiency is low, which is not conducive to use. Utility Model Content

[0005] In order to improve testing efficiency while ensuring the accuracy of strip resistance test results, this application provides a mold for strip resistance testing.

[0006] This application provides a mold for testing the resistance of strip materials, which adopts the following technical solution:

[0007] A mold for detecting the resistance of strip includes a base and a resistance detection mechanism. The base has a plurality of placement slots spaced apart for placing strips. Each placement slot is provided with a conductive contact for contacting the strip. The base is provided with an electrical connector for electrical connection with the resistance detection mechanism. The conductive contacts in the placement slots are all electrically connected to the electrical connector. The base is also provided with a limiting structure for synchronously limiting the movement of the plurality of strips.

[0008] By adopting the above technical solution, several strips are placed one by one into the corresponding placement slots during use. Then, the limiting structure simultaneously limits the strips, making them contact the conductive contacts. After that, the resistance detection mechanism can simultaneously detect the resistance of several strips, thereby achieving the purpose of detecting the resistance of multiple strips at once. This improves the detection efficiency while ensuring the accuracy of the detection results.

[0009] Preferably, the limiting structure is provided in two sets, and the two sets of limiting structures are symmetrically arranged at both ends of the strip length direction.

[0010] By adopting the above technical solution, the stability of the contact between the strip and the conductive contact is ensured during use, with the cooperation of two sets of limiting structures, thereby ensuring the accuracy of the test results.

[0011] Preferably, the limiting structure includes a first pressure plate disposed on the base and a limiting bolt threadedly connected to the first pressure plate. The first pressure plate abuts against the strip, and one end of the limiting bolt passes through the first pressure plate and is threadedly connected to the base.

[0012] By adopting the above technical solution, when in use, the cooperation of the first pressure plate and the limiting bolts achieves the purpose of simultaneously limiting several strips in the placement groove.

[0013] Preferably, a buffer pad is provided between the first pressure plate and the strip.

[0014] By adopting the above technical solution, the first pressure plate is prevented from directly contacting the strip during use, thus reducing the wear of the strip by the first pressure plate during the testing process.

[0015] Preferably, the limiting structure includes a second pressure plate rotatably connected to the base, a limiting stud fixed to the base, and a first limiting nut threadedly connected to the limiting stud. The second pressure plate has a waist-shaped hole. After one end of the limiting stud passes through the waist-shaped hole and is connected to the first limiting nut, the first limiting nut abuts against the second pressure plate.

[0016] By adopting the above technical solution, when the strip is placed in the placement groove, simply rotate the second pressure plate to make the limiting stud pass through the waist-shaped hole, and then screw the first limiting nut onto the limiting stud until the first limiting nut abuts against the second pressure plate to achieve the limiting of the second pressure plate. The overall use is simple and convenient.

[0017] Preferably, the second pressure plate is provided with a sliding plate and a second limiting nut. A rod is fixed on the sliding plate. The end of the rod away from the sliding plate passes through the second pressure plate and is threaded into the second limiting nut. An elastic element is provided between the sliding plate and the second pressure plate. The elastic element is used to drive the sliding plate to slide on the second pressure plate. The sliding plate is provided with abutting blocks for abutting the strip. The number of abutting blocks is the same as the number of placement slots and corresponds one-to-one.

[0018] By adopting the above technical solution, when the second pressure plate is rotated, the sliding distance of the sliding plate is limited by the cooperation of the second limit nut and the insertion rod. Then, by the cooperation of the sliding plate, the abutment block and the elastic element, the stability of the strip in the placement groove is ensured, and the accuracy of the resistance detection of the strip is further ensured.

[0019] Preferably, a plurality of conductive contacts are provided, and the plurality of conductive contacts are evenly spaced in the placement groove. The number of electrical connectors provided is the same as the number of conductive contacts provided in one placement groove and they are connected in a one-to-one correspondence.

[0020] By adopting the above technical solution, the stability of the strip placed on the conductive contacts is ensured during use, with the cooperation of several conductive contacts, thereby ensuring the accuracy of the test results.

[0021] Preferably, the base has a clearance groove for easy handling of the strip material, and the clearance groove is connected to the placement groove.

[0022] By adopting the above technical solution, the strip can be taken out of the placement groove through the clearance groove after the test is completed, making it easier to use.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. In use, several strips are placed one by one into the corresponding placement slots. Then, the limiting structure limits the strips simultaneously, so that the strips come into contact with the conductive contacts. After that, the resistance detection mechanism can simultaneously detect the resistance of several strips, thereby achieving the purpose of detecting the resistance of multiple strips at one time. This improves the detection efficiency while ensuring the accuracy of the detection results.

[0025] 2. The combination of buffer pad, first pressure plate and limit bolt ensures the stability of the strip when placed on the conductive contact, thereby ensuring the accuracy of the test results;

[0026] 3. The design of the clearance groove makes it easier for workers to pick up and replace the strip, improving the ease of use of the equipment. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.

[0034] This application discloses a mold for detecting the resistance of strip materials.

[0035] Example 1:

[0036] Reference Figure 1 and Figure 2 A mold for detecting the resistance of a strip includes a horizontally placed base 1 and a resistance detection mechanism 2. A placement groove 11 for placing the strip 9 to be tested is provided on the base 1. The length direction of the placement groove 11 is parallel to the length direction of the base 1. Several placement grooves 11 are provided, and the several placement grooves 11 are evenly spaced along the width direction of the base 1. In this embodiment, three placement grooves 11 are preferably provided. A conductive contact 3 is provided in each placement groove 11. An electrical connector 4 is also fixed on the base 1. The electrical connector 4 is electrically connected to the resistance detection mechanism 2, and the conductive contact 3 is electrically connected to the electrical connector 4.

[0037] Reference Figure 1 and Figure 2 In this embodiment, the base 1 is preferably made of insulating material, such as wood or plastic. The resistance detection mechanism 2 is a resistance detector. The signal acquisition connector and electrical connector 4 of the resistance detector are detachably connected. A limiting structure 5 is also provided on the base 1. The limiting structure 5 is used to limit the strip 9 in the placement groove 11. In use, the worker only needs to place one strip 9 in each placement groove 11 and ensure that the strip 9 is in contact with the conductive contact 3. Then, the limiting structure 5 limits the strip 9. Finally, the resistance detection mechanism 2 is started to achieve the purpose of synchronously detecting the resistance of several strips 9.

[0038] Reference Figure 1 and Figure 2To ensure the stability of the contact between the strip 9 and the conductive contact 3 after it is placed in the placement groove 11, a number of conductive contacts 3 are provided, and the number of conductive contacts 3 are evenly distributed along the length of the placement groove 11. In this embodiment, four conductive contacts 3 are preferably provided. The number of electrical connectors 4 is the same as the number of conductive contacts 3 in one placement groove 11, and the positions of the connectors correspond one-to-one. That is, in this application, four electrical connectors 4 are provided. In use, by connecting three conductive contacts 3 in the three placement grooves 11 that are on the same straight line to a corresponding electrical connector 4, it is ensured that all conductive contacts 3 can be electrically connected to the resistance detection mechanism 2.

[0039] Reference Figure 1 and Figure 2 In addition, after the strip 9 is inspected, in order to facilitate the workers to take the strip 9 out of the placement groove 11, a clearance groove 7 is also provided on the base 1. In this application, the clearance groove 7 divides the middle part of the placement groove 11 in the length direction, so that several placement grooves 11 are connected to the clearance groove 7, thereby improving the ease of use of the device.

[0040] Reference Figure 1 and Figure 3 In this application, two sets of limiting structures 5 are provided, and the two sets of limiting structures 5 are symmetrically arranged on both sides of the length direction of the placement groove 11. That is, the two sets of limiting structures 5 respectively limit the two ends of the strip 9 in the length direction, thereby achieving the purpose of limiting the strip 9 as a whole in the placement groove 11. Each set of limiting structures 5 consists of a first pressure plate 51 and a limiting bolt 52. The first pressure plate 51 abuts against the strip 9. The length direction of the first pressure plate 51 is parallel to the width direction of the base 1. When the first pressure plate 51 is placed on the base 1, it can abut against the strip 9 in the three placement grooves 11 at the same time. The limiting bolt 52 is threadedly connected to the first pressure plate 51, and the bottom end of the limiting bolt 52 passes through the first pressure plate 51 and is threadedly connected to the base 1.

[0041] Reference Figure 1 and Figure 3 To ensure the pressing effect of the first pressure plate 51 on the strip 9, several limiting bolts 52 are provided, and the several limiting bolts 52 are evenly spaced along the length direction of the first pressure plate 51. In this embodiment, four limiting bolts 52 are provided. That is, when in use, after a strip 9 is placed in each placement slot 11, the first pressure plate 51 can be placed on one end of the strip 9, and then the four limiting bolts 52 can be tightened one by one. In this way, the first pressure plate 51 can be stably fixed on the base 1, thereby limiting the strip 9.

[0042] Reference Figure 2 and Figure 3Meanwhile, in order to prevent the first pressure plate 51 from directly contacting the strip 9 and causing damage to the strip 9, a buffer pad 6 is provided between the first pressure plate 51 and the strip 9 in this application. The number of buffer pads 6 is the same as that of the placement grooves 11 and they are distributed in a one-to-one correspondence. That is, when in use, a buffer pad 6 is provided in each placement groove 11. During testing, the strip 9 is first placed into the placement groove 11, then the buffer pad 6 is placed in, and finally the first pressure plate 51 is covered. The first pressure plate 51 presses the buffer pad 6, and the buffer pad 6 abuts against the strip 9, thereby indirectly limiting the strip 9 and avoiding damage to the strip 9.

[0043] Reference Figure 2 and Figure 3 In this application, in order to further ensure the stability of the strip 9 when placed in the placement groove 11, positioning protrusions 8 are formed on the inner sides of both ends of the placement groove 11 in the length direction. The positioning protrusions 8 are adapted to the grooves at both ends of the strip 9 in the length direction.

[0044] The implementation principle of this application embodiment is as follows: In use, the first pressure plate 51 is first removed from the base 1, and then the strip 9 to be tested is placed one by one into the placement slots 11 at different positions. After all the placement slots 11 have a strip 9 placed in them, a buffer pad 6 is placed in each placement slot 11. Then, the two first pressure plates 51 are respectively placed on the ends of the placement slots 11 in the length direction. Finally, the limiting bolts 52 are tightened to fix the first pressure plates 51. Then, the resistance detection mechanism 2 is started, so that the resistance of multiple strips 9 can be detected simultaneously. The overall detection efficiency is more efficient than the existing method of detecting one by one.

[0045] Example 2:

[0046] Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that in this embodiment, the limiting structure 5 consists of a second pressure plate 53, a limiting stud 54, and a first limiting nut 55. One end of the second pressure plate 53 is hinged to the base 1, and the other end of the second pressure plate 53 is a movable end. The bottom end of the limiting stud 54 is fixed to the base 1, and the top end of the limiting stud 54 is set vertically upward. The first limiting nut 55 is threadedly engaged with the limiting stud 54. A waist-shaped hole 531 is provided at the movable end of the second pressure plate 53. In use, by rotating the second pressure plate 53, the limiting stud 54 is gradually inserted into the waist-shaped hole 531. When the movable end of the second pressure plate 53 rotates close to the buffer pad 6, the top end of the limiting stud 54 passes through the waist-shaped hole 531. At this time, the first limiting nut 55 can be screwed onto the limiting stud 54 until the first limiting nut 55 presses the second pressure plate 53 tightly. Then, the buffer pad 6 can be pressed into the placement groove 11 by the second pressure plate 53.

[0047] Reference Figure 4 and Figure 5 In this embodiment, to further improve the ease of use of the device, the first limiting nut 55 is a rectangular nut, that is, the length of the first limiting nut 55 is greater than the width of the oblong hole 531 and less than the length of the oblong hole 531, and the width of the first limiting nut 55 is less than the width of the oblong hole 531; that is, when in use, when the first limiting nut 55 is rotated to be perpendicular to the oblong hole 531, the second pressure plate 53 can be limited; when the first limiting nut 55 is rotated to be parallel to the oblong hole 531, rotating the second pressure plate 53 can allow the first limiting nut 55 to pass through the oblong hole 531 until the second pressure plate 53 is fully opened, making the overall use simpler and more convenient.

[0048] Reference Figure 4 and Figure 5 To ensure the limiting effect of the second pressure plate 53, a sliding plate 532 is provided on the side of the second pressure plate 53 facing the base 1, and a second limiting nut 533 is provided on the other side of the second pressure plate 53. A plug rod 534 is welded and fixed on the sliding plate 532. One end of the plug rod 534 passes through the second pressure plate 53 and is threaded into the second limiting nut 533. An elastic element 535 is also provided between the sliding plate 532 and the second pressure plate 53. In this embodiment, the elastic element 535 is a spring. The spring is sleeved on the plug rod 534, and one end of the spring abuts against the sliding plate 532, and the other end of the spring abuts against the second pressure plate 53. In use, the sliding distance of the sliding plate 532 on the second pressure plate 53 is adjusted by the cooperation of the second limiting nut 533 and the elastic element 535.

[0049] Reference Figure 4 and Figure 5 An abutment block 536 is integrally formed on the side of the sliding plate 532 facing the base 1. The abutment block 536 can be embedded in the placement groove 11 and abut against the buffer pad 6. In this application, the number of abutment blocks 536 is the same as the number of placement grooves 11 and their positions correspond one-to-one. In use, the cooperation of the elastic member 535, the sliding plate 532 and the abutment block 536 ensures the limiting effect of the second pressure plate 53 on the buffer pad 6, which helps to ensure the stability of the strip 9 placed in the placement groove 11.

[0050] The implementation principle of this application embodiment is as follows: In use, first tighten the first limiting nut 55 so that the length direction of the first limiting nut 55 is parallel to the length direction of the first waist-shaped hole 531. Then rotate the first pressure plate 51 to lift the first pressure plate 51. Then place the strip 9 to be tested one by one into the placement slots 11 at different positions. After all the placement slots 11 have one strip 9, place a buffer pad 6 into each placement slot 11. Then rotate the two first pressure plates 51 respectively so that they cover the placement slots 11 and make the abutment block 536 abut against the buffer pad 6. Finally, tighten the limiting bolt 52 to press the first pressure plate 51. Then start the resistance detection mechanism 2 to achieve the purpose of synchronous detection of the resistance of multiple strips 9. The overall use process is simpler and more convenient.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
