Description

Technical Field

[0001] This utility model belongs to the field of solder joint testing technology, and in particular relates to a micro solder joint strength mechanical testing device. Background Technology

[0002] Micro solder joints refer to a soldering technique that uses extremely small solder joints to connect electronic components. It is commonly used in high-density, high-precision electronic devices, especially in modern electronic products such as mobile phones, tablets, computer chips, and other microelectronic devices.

[0003] According to the published patent CN206362630U, a lead wire solder joint strength testing device includes a base and a tensile gauge, as well as a fixing component, a left-right moving mechanism, and a fixing mechanism. The fixing mechanism and the left-right moving mechanism are disposed on the base. The tensile gauge is connected to the left-right moving mechanism, and the fixing component is connected to the tensile gauge. This device is convenient for users and can accurately test the solder joint strength. However, it still has the following shortcomings:

[0004] The patent does not securely fix the object to be tested. If the object to be tested becomes loose or moves during the testing process, it may lead to inaccurate test results. Therefore, we propose a micro-weld joint strength mechanical testing device. Utility Model Content

[0005] The purpose of this invention is to provide a micro-weld joint strength mechanical testing device. By manually rotating the threaded rod, the disc is moved. When the disc moves, the fixed block moves, which in turn moves the clamp. This solves the problem of the tested object becoming loose or moving during the testing process.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a micro-weld joint strength mechanical testing device, including a shell, a groove is provided inside the shell, a controller is fixedly connected to the outer wall of the shell, a fixing mechanism is provided on the shell, and a testing mechanism is provided on the shell;

[0008] The fixing mechanism includes a threaded barrel slidably connected to the inner wall of the groove. A fixing block is fixedly connected to the top of the threaded barrel. A second fixing block is fixedly connected to the top of the fixing block. A threaded rod is threadedly connected to the inner wall of the second fixing block. A third fixing block is rotatably connected to the outer wall of the threaded rod. A second groove is formed inside the third fixing block. A disc is fixedly connected to the outer wall of the threaded rod. A first sliding groove is formed inside the second fixing block. A clamp is slidably connected to the inner wall of the first sliding groove. A second sliding groove is formed inside the third fixing block.

[0009] Furthermore, there are two threaded barrels, and the disc is located inside the second groove.

[0010] Furthermore, there are two slide grooves in total, and the inner wall of the second slide groove is slidably connected to the outer wall of the fixture.

[0011] Furthermore, the testing mechanism includes a motor fixedly connected to the outer wall of the housing, and the output shaft of the motor is fixedly connected to a reverse threaded rod via a coupling.

[0012] Furthermore, the outer wall of the reverse threaded rod is rotatably connected to the inner wall of the housing, and the outer wall of the reverse threaded rod is threadedly connected to the inner wall of the threaded barrel.

[0013] Furthermore, a sliding groove three is provided inside the housing, and the inner wall of the sliding groove three is slidably connected to the outer wall of the threaded barrel.

[0014] Furthermore, a fixed frame is fixedly connected to the outer wall of the shell, a threaded rod 2 is rotatably connected to the inner wall of the fixed frame, a threaded barrel 2 is threadedly connected to the outer wall of the threaded rod 2, and a fixed block 4 is fixedly connected to the outer wall of the threaded barrel 2.

[0015] Furthermore, a hydraulic device is fixedly connected to the outer wall of the four fixed blocks, a cutter is fixedly connected to the outer wall of the hydraulic device, and a controller is fixedly connected to the outer wall of the four fixed blocks.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting up a clamp, first fixes the part to be tested, places both ends between two clamps, and then manually rotates the threaded rod one to drive the disc to move. When the disc moves, it will drive the fixing block three to move. When the fixing block three moves, it will drive the clamp to move. As the clamp moves, due to the existence of sliding groove one and sliding groove two, the clamps will move closer to each other while moving, clamping and fixing the part to be tested. This mechanism can clamp the part that needs to be tested for solder joints, so that the force applied during the test can be fully applied to the solder joint, improving the accuracy of the test.

[0018] 2. This utility model incorporates a threaded rod. When a weld joint needs to be tested, the controller starts the motor, causing the reverse threaded rod to rotate. As the reverse threaded rod rotates, the two threaded barrels move away from each other, which in turn causes the fixing blocks to move away from each other, thus stretching the clamped part. The controller then slowly increases the force applied by the motor until the weld joint breaks, testing the lateral tensile force of the weld joint. After that, a new part needs to be tested. This mechanism can test the maximum load-bearing capacity and shear strength of the weld joint through lateral tensile force and vertical cutting force.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] The fixing mechanism 2 includes a threaded barrel 201 slidably connected to the inner wall of the groove 102. A fixing block 202 is fixedly connected to the top of the threaded barrel 201, and a second fixing block 203 is fixedly connected to the top of the fixing block 202. A threaded rod 204 is threadedly connected to the inner wall of the second fixing block 203. By setting the threaded barrel 201, when the threaded barrel 201 moves, it will drive the fixing block 202 to move, which can easily adapt to the test items of different lengths. A third fixing block 205 is rotatably connected to the outer wall of the first fixing rod 204. A second groove 206 is opened inside the third fixing block 205. A disc 207 is fixedly connected to the outer wall of the first fixing rod 204. 3. An internal sliding groove 208 is provided. Due to the inclined design of the sliding groove 208, the clamps 209 will move closer to each other when sliding in the sliding groove 208. The clamps 209 are slidably connected to the inner wall of the sliding groove 208. The fixed block 3 205 has an internal sliding groove 210. There are two threaded barrels 201. The disc 207 is located inside the groove 206. There are two sliding grooves 208. By setting the groove 206, when the disc 207 moves, it will drive the fixed block 3 205 to move through the groove 206. The inner wall of the sliding groove 210 is slidably connected to the outer wall of the clamps 209.

[0033] The testing mechanism 3 includes a motor 301 fixedly connected to the outer wall of the housing 101. The output shaft of the motor 301 is fixedly connected to a reverse threaded rod 302 via a coupling. The outer wall of the reverse threaded rod 302 is rotatably connected to the inner wall of the housing 101. The outer wall of the reverse threaded rod 302 is threadedly connected to the inner wall of the threaded barrel 201. By setting the motor 301, the motor 301 is started to drive the reverse threaded rod 302 to rotate. A sliding groove 303 is provided inside the housing 101. The inner wall of the sliding groove 303 is slidably connected to the outer wall of the threaded barrel 201.

[0034] A fixed frame 304 is fixedly connected to the outer wall of the housing 101. A threaded rod 305 is rotatably connected to the inner wall of the fixed frame 304. A threaded barrel 306 is threadedly connected to the outer wall of the threaded rod 305. A fixed block 307 is fixedly connected to the outer wall of the threaded barrel 306. By setting the threaded rod 305, when the threaded rod 305 is rotated, the threaded barrel 306 will move. When the threaded barrel 306 moves, the fixed block 307 will move, so that the cutter 309 is above the welding point. A hydraulic device 308 is fixedly connected to the outer wall of the fixed block 307. The cutter 309 is fixedly connected to the outer wall of the hydraulic device 308. A controller 310 is fixedly connected to the outer wall of the fixed block 307.

[0035] One specific application of this embodiment is:

[0036] First, fix the part to be tested, placing both ends between the two clamps 209. Then, manually rotate the threaded rod 204 to move the disc 207. As the disc 207 moves, it moves the fixing block 205, which in turn moves the clamps 209. Due to the presence of the sliding grooves 208 and 210, the clamps 209 move closer together, clamping and fixing the part to be tested. This mechanism can clamp the part whose weld joints need to be tested, ensuring that the force applied during testing is fully applied to the weld joint, improving testing accuracy. When the weld joint needs to be tested, start the motor 301 via the controller 103, which drives the reverse threaded rod 302 to rotate. As rod 302 rotates, the two threaded barrels 201 move away from each other, which in turn moves the fixing blocks 202 away from each other, thus stretching the clamped part. Then, controller 103 slowly increases the force applied by motor 301 until the weld joint breaks, testing the lateral tensile force of the weld joint. Then, a new part to be tested is replaced, and threaded rod 205 is manually rotated, moving threaded barrel 206, which in turn moves fixing block 407. When fixing block 407 moves directly above the weld joint, controller 210 activates hydraulic pump 308, driving cutter 309 to press down, thus cutting the weld joint to test its shear strength. This mechanism can test the maximum load-bearing capacity and shear strength of the weld joint through lateral tensile force and vertical cutting force.
