Description
Technical Field
[0001] This utility model relates to the field of conductive adhesive performance testing technology, specifically a conductive adhesive peel strength test fixture. Background Technology
[0002] Conductive adhesive is an adhesive that becomes conductive after curing or drying. It can connect various conductive materials together, creating an electrical path between them. In the electronics industry, conductive adhesive has become an indispensable new material. To determine the bonding strength between conductive adhesive and conductive materials, a peel strength test is usually required. This test involves applying a vertical tensile force to separate the two materials and recording the maximum force required, thus reflecting the bonding strength between them. The peel strength test is a key step in evaluating the reliability of the bond and the stability of use. As a core auxiliary device, the clamping effect, adjustment flexibility, and applicability of the test fixture directly affect the accuracy of the test data and the efficiency of the testing work.
[0003] Traditional fixtures have fixed clamping structures, making it difficult to adapt to conductive adhesives of different widths and diameters. When facing diverse testing needs, different fixtures need to be changed frequently, which not only increases equipment costs but also significantly reduces testing efficiency. The applicable range of fixtures is limited, and their flexibility is weak.
[0004] Therefore, it is necessary to provide a new conductive adhesive peel strength test fixture to solve the above-mentioned technical problems. Utility Model Content

Rod 2, four strip blocks are fixedly installed on the double-ended screw 2, two circular sleeves are slidably installed on the four strip blocks, rectangular blocks are threaded onto the two circular sleeves, racks are fixedly installed on the top of the two rectangular blocks, two vertical plates are fixedly installed on the top of the two connecting plates, two connecting rods are fixedly installed between the four vertical plates, notched gears are rotatably fitted on the two connecting rods, the two notched gears mesh with the two racks respectively, and clamping blocks are fixedly installed on the two notched gears.
[0007] Preferably, a horizontal plate is fixedly installed on the inner wall of the mounting groove, and two movable holes are provided on the horizontal plate, with the two sliding blocks slidably installed in the two movable holes respectively.
[0008] Preferably, each of the two circular sleeves has two strip holes on its inner wall, and the four strip blocks are slidably installed in the four strip holes respectively.
[0009] Preferably, a limiting block is fixedly sleeved on the second double-ended screw, and an annular block is fixedly sleeved on the side of each of the two circular sleeves that are close to each other. A handle is fixedly installed on one end of both the first double-ended screw and the second double-ended screw.
[0010] Preferably, two upright plates are fixedly installed on the top of each of the two connecting plates, and the four upright plates are respectively located on both sides of the two rectangular blocks, and the four upright plates are in sliding contact with the two rectangular blocks respectively.
[0011] Preferably, multiple clamping teeth are fixedly installed on the side of each of the two clamping blocks that are close to each other, and the multiple clamping teeth are distributed in an alternating manner.
[0012] Preferably, both sliding blocks have forward-facing ball bearings at their bottoms, and both ball bearings are in contact with the bottom inner wall of the connecting block.
[0013] Compared with related technologies, the conductive adhesive peel strength test fixture provided by this utility model has the following advantages: In this invention, traditional clamps are mostly designed with fixed specifications, making it difficult to adapt to conductive adhesives of different widths and diameters. However, in this invention, through the cooperation structure of a double-ended screw and sliding blocks, rotating the double-ended screw can drive the two sliding blocks to move away or closer synchronously. Then, through components such as a connecting plate and a circular sleeve, the two clamping blocks are driven to adjust the distance between them. This adjustment function can meet the clamping requirements of conductive adhesives of different specifications within a certain range, eliminating the need for frequent clamp replacements, significantly improving the flexibility of the equipment, reducing testing costs, and making it suitable for diverse conductive adhesive testing scenarios. The two clamping blocks of the clamp are fixedly installed with multiple staggered clamping teeth on the side close to each other, which can greatly increase the friction and claw force between the clamping blocks and the conductive adhesive. This solves the problem of conductive adhesives loosening during peel testing due to insufficient clamping force in traditional clamps, ensuring a stable testing process and improving the accuracy of test data.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0017] Please refer to the following: Figures 1-5 ,in, Figure 1 This is a front view structural diagram of the present utility model; Figure 2 This is a frontal sectional view of the present invention. Figure 3 This is a side sectional view of the present invention. Figure 4 This is a side sectional view of the connecting block, the vertical plate, and the notched gear shown in this utility model. Figure 5This is a side sectional view of the connecting block and sliding block shown in this invention. The conductive adhesive peel strength test fixture includes: a connecting block 1, a mounting groove 2 on the connecting block 1, an adapter block 3 fixedly mounted on one inner wall of the mounting groove 2, a double-ended screw 4 rotatably mounted on the adapter block 3, the right end of the double-ended screw 4 extending outside the connecting block 1, the double-ended screw 4 rotatably connected to the connecting block 1, two sliding blocks 5 threadedly mounted on the double-ended screw 4, each sliding block 5 having a ball bearing at its bottom, both balls bearing contact with the bottom inner wall of the connecting block 1, the two balls bearing increasing the smoothness of movement of the two sliding blocks 5 and reducing wear, a connecting plate 6 fixedly mounted on the top of each sliding block 5, both connecting plates 6 being L-shaped, an adapter block 7 fixedly mounted on one inner wall of the mounting groove 2, the adapter block 7 being directly above the adapter block 3, a double-ended screw 8 rotatably mounted on the adapter block 7, the right end of the double-ended screw 8 extending outside the connecting block 1, the double-ended screw 8... Four strip blocks 9 are fixedly installed on the screw 2 8, with each pair of strip blocks 9 corresponding to the others. Two circular sleeves 10 are slidably installed on the four strip blocks 9. The outer walls of the two circular sleeves 10 are provided with threaded grooves. Rectangular blocks 11 are threaded onto each of the two circular sleeves 10. A rack 12 is fixedly installed on the top of each of the two rectangular blocks 11. Two vertical plates 13 are fixedly installed on the top of each of the two connecting plates 6. Two connecting rods 14 are fixedly installed between the four vertical plates 13. Notched gears 15 are rotatably fitted on each of the two connecting rods 14. The two notched gears 15 mesh with the two racks 12 respectively. Clamping blocks 16 are fixedly installed on the missing teeth of the two notched gears 15. Multiple clamping teeth are fixedly installed on the side of the two clamping blocks 16 that are close to each other. The multiple clamping teeth are staggered and can increase the clamping force of the clamping blocks 16, reducing the possibility of the conductive adhesive coming loose from between the two clamping blocks 16.
[0018] In order to limit the movement trend and range of the two sliding blocks 5 and increase the stability of the two sliding blocks 5, in this method, a horizontal plate is fixedly installed on the inner wall of the mounting groove 2, and two moving holes are opened on the horizontal plate. The two sliding blocks 5 are slidably installed in the two moving holes respectively.
[0019] In order to enable the two circular sleeves 10 to rotate together when the double-ended screw 8 rotates, and at the same time ensure that the two circular sleeves 10 can slide on the double-ended screw 8, in this method, two strip holes are opened on the inner wall of each of the two circular sleeves 10, and four strip blocks 9 are slidably installed in the four strip holes respectively.
[0020] To prevent the two rectangular blocks 11 from falling off the two circular sleeves 10 and to limit the range of movement of the two rectangular blocks 11, in this method, a limiting block is fixedly sleeved on the double-ended screw 8, and an annular block is fixedly sleeved on the side of the two circular sleeves 10 that are close to each other. A handle is fixedly installed on one end of the double-ended screw 4 and the double-ended screw 8.
[0021] In order to restrict the movement direction of the two rectangular blocks 11 and allow them to slide left and right, in this method, two upright plates are fixedly installed on the top of each of the two connecting plates 6. The four upright plates are located on both sides of the two rectangular blocks 11, and the four upright plates are in sliding contact with the two rectangular blocks 11 respectively.
[0022] The working principle of the conductive adhesive peel strength test fixture provided by this utility model is as follows: In the initial state, the two rectangular blocks 11 and the two racks 12 are close to each other, and the two clamping blocks 16 are open. When testing is required, place one end of the conductive adhesive to be tested between the two clamping blocks 16, and then rotate the double-ended screw 8. The double-ended screw 8 drives the two circular sleeves 10 to rotate simultaneously through the four strip blocks 9. When the two circular sleeves 10 rotate, the two rectangular blocks 11 slide away from each other. The two rectangular blocks 11 drive the two racks 12, and the two racks 12 drive the two clamping blocks 16 to move closer to each other through the two notched gears 15, until the two clamping blocks 16 gradually merge and firmly clamp the conductive adhesive. Then stop rotating the double-ended screw 8. When it is necessary to remove the conductive adhesive from between the two clamping blocks 16, simply rotate the double-ended screw 8 in the opposite direction.
[0023] When testing conductive adhesives of other specifications, if the width or diameter of the conductive adhesive is larger, the double-ended screw 4 can be rotated. The two sliding blocks 5 move simultaneously on the double-ended screw 4, moving away from each other. The two sliding blocks 5 drive the two connecting plates 6 to move simultaneously, causing the two circular sleeves 10 to slide on the four strip blocks 9. The distance between the two clamping blocks 16 gradually increases until the two clamping blocks 16 can accommodate and clamp the conductive adhesive to be tested. Then, the adjustment of the double-ended screw 4 can be stopped. The easily adjustable clamping blocks 16 can be used for conductive adhesives of different specifications within a certain range, improving the flexibility and applicability of the fixture.
[0024] Compared with related technologies, the conductive adhesive peel strength test fixture provided by this utility model has the following advantages: Traditional clamps are mostly designed with fixed specifications, making it difficult to adapt to conductive adhesives of different widths and diameters. However, in this invention, through the cooperation structure of the double-ended screw 4 and the sliding block 5, rotating the double-ended screw 4 can drive the two sliding blocks 5 to move away or closer simultaneously. Then, through the connecting plate 6, the circular sleeve 10 and other components, the two clamping blocks 16 are driven to adjust the distance. This adjustment function can meet the clamping requirements of conductive adhesives of different specifications within a certain range, eliminating the need for frequent clamp changes, significantly improving the flexibility of the equipment, reducing testing costs, and making it suitable for diverse conductive adhesive testing scenarios. The two clamping blocks 16 of the clamp are fixedly installed with multiple staggered clamping teeth on the side close to each other, which can greatly increase the friction and claw force between the clamping blocks 16 and the conductive adhesive. This solves the problem of the conductive adhesive loosening during the peel test due to insufficient clamping force in traditional clamps, ensuring the stability of the testing process and improving the accuracy of the test data.
