[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The high-precision AI circuit testing fixture involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Reference Figures 1 to 6This utility model provides a high-precision AI circuit testing fixture, including a testing body 1, and further including: a fixing mechanism 2 and a mounting mechanism 3. The bottom end of the testing body 1 is fixedly connected to the top end of the mounting mechanism 3, and the bottom end of the fixing mechanism 2 is fixedly connected to the top end of the mounting mechanism 3. The testing body 1 includes a base 101, and a testing box 102 is fixedly connected to the top end of the base 101. The mounting mechanism 3 includes a substrate 301, and the top end of the substrate 301 is fixedly connected to the bottom end of the base 101. The fixing mechanism 2 includes a base plate 201, and a column 205 is fixedly connected to the bottom end of the base plate 201. The bottom end of the column 205 is fixedly connected to the top end of the substrate 301. A handle 303 is fixedly connected to the base plate 301. A through hole 306 is opened at the top of the base plate 301. A support column 302 is movably connected to the side of the through hole 306. Both ends of the support column 302 are provided with threads 307. A first fastening screw block 304 is threaded to the top of the support column 302, and a second fastening screw block 309 is threaded to the bottom of the support column 302. When the device is stored or carried, the support column 302 passes through the placement slots 305 on the two base plates 301, so that the fixing mechanism 2 and the mounting mechanism 3 on the two base plates 301 are staggered. The first fastening screw block 304 is tightened by the thread 307 to fix the two base plates 301. The device can be picked up by the handle 303.
[0024] The substrate 301 has a placement groove 305 at the top of the corresponding through hole 306. The support column 302 is fixedly connected to the side of the limiting ring 308. When the upper and lower substrates 301 are facing each other, the two limiting rings 308 are respectively attached to the top of the bottom substrate 301 and the bottom of the top substrate 301 to limit the two substrates 301 and prevent them from falling.
[0025] The bottom end of the base plate 201 is movably fitted with a bidirectional threaded shaft 208, and the side of the bidirectional threaded shaft 208 is threadedly connected with a threaded block 207. The top end of the base plate 201 is provided with a through groove 204 corresponding to the position of the bidirectional threaded shaft 208. The side of the through groove 204 is movably connected to the side of the threaded block 207. The top end of the threaded block 207 is fixedly connected with a clamping plate 202. When the AI circuit board to be tested is placed on the base plate 201, the bidirectional threaded shaft 208 rotates and drives the threaded blocks 207 on both sides to slide along the through groove 204 through the threads, so that the clamping plates 202 on both sides are tightly attached to the diagonal corners of the AI circuit to be tested for fixation.
[0026] The bidirectional threaded shaft 208 has a worm gear 206 fixedly sleeved on its side. The bottom end of the base plate 201 is fixedly connected to a servo motor 209. The output shaft of the servo motor 209 is fixedly connected to a worm 210. The side of the worm 210 meshes with the side of the worm gear 206. The servo motor 209 drives the worm 210 to rotate, and the bidirectional threaded shaft 208 rotates through the meshing of the worm gear 206 and the worm 210.
[0027] The clamping plate 202 has a groove 203 on its side. The groove 203 is a right-angle structure, which makes it easy to hold the circuit board diagonally.
[0028] The groove 203 has a mounting hole 212 on its side. A buffer spring 213 is fixedly connected to the side of the mounting hole 212. A pressure spring 215 is fixedly connected to the side of the buffer spring 213. A reset spring 214 is fixedly connected to the side of the mounting hole 212. A pressure block 211 is fixedly connected to the side of the reset spring 214. When the grooves 203 on both sides contact the circuit board, they first contact the pressure block 211. When the pressure block 211 is retracted into the mounting hole 212, it contacts the pressure spring 215. When the pressure springs 215 on both sides evenly press the pressure block 211 into contact, the pressure spring 215 controls the servo motor 209 to automatically stop, reducing manual control.
[0029] The working principle of this utility model is as follows: During the testing process, the circuit board is placed in the middle position on the base plate 201. The servo motor 209 is started to drive the worm gear 210 to rotate. The worm wheel 206 meshes with the worm gear 210 to drive the bidirectional threaded shaft 208 to rotate. The thread drives the threaded blocks 207 on both sides to slide along the through groove 204, so that the grooves 203 on the two clamping plates 202 hold the circuit board diagonally and contact the pressure block 211. When the pressure block 211 is retracted into the mounting hole 212, the pressure block 211 contacts the pressure spring 215. When the pressure springs 215 on both sides evenly press the block 211, the pressure springs 215 control the servo motor 209 to stop automatically, and the circuit board under test is tightly pressed against the servo motor 209. The circuit board is fixed diagonally, and the circuit board is connected to the internal circuit of the test box 102 for testing via a connecting wire. After the test is completed, it is started in reverse. The servo motor 209 causes the two side clamps 202 to loosen the circuit board, and the support column 302 is inserted into the placement groove 305 on the bottom substrate 301. The second fastening screw 309 is fixed to the bottom of the support column 302 by threads and tightened so that the through hole 306 is put into the placement groove 305. Then, the placement groove 305 on the other mounting mechanism 3 is put onto the support column 302. Then, the first fastening screw 304 is tightened to fix the upper substrate 301, so that the fixing mechanism 2 and the test body 1 on the upper and lower substrates 301 are aligned for easy storage.
[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
