Description

Technical Field

[0001] This invention relates to the field of CPU board, DI board, and OPT board testing technology, specifically to a CPU board, DI board, and OPT board testing device. Background Technology

[0002] In the field of optical communication testing, traditional testing methods generally rely on manual operation. During testing, operators need to manually connect the product under test to the test backplane and rely on visual observation and judgment of the working status of LED indicators or the connection status of optical modules.

[0003] Because the entire process of mating and testing is done manually, not only is the testing of individual products time-consuming, resulting in low overall production efficiency, but manual mating is also prone to physical damage to the connectors due to uneven force or angular deviation. Furthermore, judging the brightness and color of LEDs by the naked eye is easily affected by subjective visual fatigue and ambient light interference, leading to inaccurate test results. Summary of the Invention

[0004] This invention provides a testing device for CPU boards, DI boards, and OPT boards, which solves the problems of low efficiency and error-proneness caused by manual operation and improves testing efficiency.

[0005] To solve the above-mentioned technical problems, the present invention provides a CPU board, DI board, and OPT board testing device, including a lower housing, a testing mechanism, a quick clamp, and a backplane assembly. The testing mechanism is disposed on the lower housing and is used to realize automatic insertion, testing, and data acquisition of the product under test.

[0006] The quick clamp is fixed to the testing mechanism to hold the product to be tested;

[0007] The backplate assembly is disposed on one side of the testing mechanism and is used to provide a testing interface; wherein:

[0008] The testing mechanism includes a base plate, a drive component fixedly connected to the bottom of the base plate, a motion component slidably connected to the top of the base plate, the drive component driving the motion component to move linearly, a mating component fixedly connected to the motion component, and a carrier plate component slidably connected to the top of the base plate, the carrier plate component fixing the product under test, and the mating component automatically mating and unmating with the product under test driven by the motion component to perform testing.

[0009] Furthermore, the drive assembly includes a first mounting plate and a second mounting plate, which are symmetrically and fixedly connected to the bottom of the base plate. A servo motor is fixedly connected to the first mounting plate, and a ball screw is rotatably connected between the first mounting plate and the second mounting plate. The output end of the servo motor is connected to the input end of the ball screw. A ball nut is threaded on the outer surface of the ball screw, and a fixing plate is fixedly connected to the ball nut.

[0010] Furthermore, the motion component includes a fixed frame, which is slidably connected to the top of the base plate, and the bottom of the fixed frame is fixedly connected to the fixed plate. A support platform is fixedly connected to the inner bottom wall of the fixed frame, and the support platform is used to fix the insertion component.

[0011] Furthermore, fixed seats are fixedly connected to both sides of the top of the fixed frame, and push rods are fixedly connected to the fixed seats. Limiting rings are fixedly sleeved on the outer surface of the push rods.

[0012] Furthermore, the mating assembly includes a mounting bracket, on one side of the inner bottom wall of the mounting bracket, a first cylinder is fixedly connected, and the output end of the first cylinder is fixedly connected to an optical fiber plug.

[0013] Furthermore, a second cylinder is fixedly connected to the other side of the bottom wall of the mounting frame, and a light guide column is fixedly connected to the output end of the second cylinder.

[0014] Furthermore, multiple optical modules are fixedly connected to the center of the mounting frame, and a push-pull rod is fixedly connected to the inner top wall of the mounting frame.

[0015] Furthermore, the carrier plate assembly includes a floating plate, which is slidably connected to the top of the base plate. The carrier plate is fixedly connected to the top of the floating plate. The product to be tested is placed on the top of the floating plate and the carrier plate. Two quick clamps are symmetrically fixedly connected to both sides of the top of the floating plate.

[0016] Both sides of the top of the floating plate are fixedly connected to a stop block, and the stop block has a through hole in the middle, and the push rod is slidably connected in the through hole.

[0017] Furthermore, the backplane assembly includes a backplane, on which test positions, CPU test positions, and power test positions are respectively provided.

[0018] Furthermore, a protective frame is fixedly connected to the top of the lower housing, and the protective frame is disposed around the testing mechanism and the backplate assembly;

[0019] The bottom of the lower enclosure is fixedly connected to a cabinet, which is used to house control lines.

[0020] By employing the above technical solution, the present invention provides a testing device for CPU boards, DI boards, and OPT boards, which has at least the following beneficial effects:

[0021] 1. The present invention provides a test mechanism that integrates a drive component, a motion component, an interlocking component, and a carrier board component. The product under test is placed on the carrier board component and fixed by a quick clamp. The drive component drives the motion component to move the interlocking component close to the product under test and complete the interlocking and testing. This solves the problems of low efficiency and error caused by manual operation and improves the testing efficiency.

[0022] 2. In this invention, the operation of the servo motor can drive the ball screw to rotate. The ball screw and the ball nut can convert the rotational motion into linear motion. The ball nut drives the fixed plate to move synchronously, which facilitates the movement of the motion component and the interlocking component towards the carrier plate component.

[0023] 3. In this invention, the operation of the first cylinder can drive the fiber optic plug to move linearly, enabling precise docking between the fiber optic plug and the product under test. The operation of the second cylinder can drive the light guide column to move, ensuring stable docking between the light guide column and the optical interface of the product under test, thus improving the accuracy of optical signal acquisition.

[0024] 4. In this invention, when the drive component moves the motion component and the interlocking component toward the carrier plate component, the push rod slides in the through hole of the stop block, and the limiting ring abuts against the stop block. The drive component continues to move, which can push the carrier plate component closer to the back plate component, and make the detection end of the product under test automatically interlock with the test position on the back plate component. After the product under test and the test position are interlocked, the first cylinder and the second cylinder automatically extend to complete the corresponding interlocking action.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figure 1 , Figure 2 and Figure 3As shown, a CPU board, DI board, and OPT board testing device includes a lower housing 1, a testing mechanism 2, a quick clamp 3, and a backplane assembly 4. The testing mechanism 2 is mounted on the lower housing 1 and is used to realize automatic insertion, testing, and data acquisition of the product 7 to be tested.

[0040] The quick clamp 3 is fixed to the testing mechanism 2 to fix the product to be tested 7;

[0041] The backplate assembly 4 is located on one side of the test mechanism 2 and is used to provide a test interface; wherein:

[0042] The testing mechanism 2 includes a base plate 21. A drive component 22 is fixedly connected to the bottom of the base plate 21, and a motion component 23 is slidably connected to the top of the base plate 21. The drive component 22 is used to drive the motion component 23 to move linearly. A mating component 24 is fixedly connected to the motion component 23. A carrier plate component 25 is also slidably connected to the top of the base plate 21. The carrier plate component 25 is used to fix the product under test. The mating component 24 is driven by the motion component 23 to automatically insert and unplug with the product under test 7 for testing.

[0043] The present invention provides a test mechanism 2 that integrates a drive component 22, a motion component 23, an interlocking component 24, and a carrier plate component 25. The product under test 7 is placed on the carrier plate component 25 and fixed by a quick clamp 3. The drive component 22 drives the motion component 23 to move the interlocking component 24 close to the product under test 7 and complete the interlocking and testing. This solves the problems of low efficiency and error caused by manual operation and improves the testing efficiency.

[0044] like Figure 3 As shown, a limiter 26 is also fixedly connected to the top of the base plate 21, and limit blocks are fixedly connected to both sides of the carrier plate assembly 25. The limiter 26 is set in correspondence with the limit block, which can limit the distance that the carrier plate assembly 25 can move.

[0045] like Figure 4 and Figure 5 As shown, the drive assembly 22 includes a first mounting plate 221 and a second mounting plate 223. The first mounting plate 221 and the second mounting plate 223 are symmetrically fixedly connected to the bottom of the base plate 21. A servo motor 222 is fixedly connected to the first mounting plate 221. A ball screw 224 is rotatably connected between the first mounting plate 221 and the second mounting plate 223. The output end of the servo motor 222 is connected to the input end of the ball screw 224. A ball nut 225 is threaded on the outer surface of the ball screw 224. A fixing plate 226 is fixedly connected to the ball nut 225.

[0046] A drive wheel is fixedly mounted on the output end of the servo motor 222, and a driven wheel is fixedly mounted on the input end of the ball screw 224. The drive wheel is connected to the driven wheel via a transmission belt.

[0047] The operation of the servo motor 222 can drive the ball screw 224 to rotate. The ball screw 224, in conjunction with the ball nut 225, can convert the rotational motion into linear motion. The ball nut 225 drives the fixed plate 226 to move synchronously, which facilitates the movement of the motion component 23 and the mating component 24 towards the carrier plate component 25.

[0048] like Figure 6 As shown, the motion component 23 includes a fixed frame 231, which is slidably connected to the top of the base plate 21. The bottom of the fixed frame 231 is fixedly connected to the fixed plate 226. A support platform 232 is fixedly connected to the inner bottom wall of the fixed frame 231. The support platform 232 facilitates the fixing of the insertion component 24, ensuring the stability of the fixing and preventing displacement deviation during the test.

[0049] Both sides of the top of the fixed frame 231 are fixedly connected to fixed seats 233, and push rods 234 are fixedly connected to the fixed seats 233. Limiting rings 235 are fixedly sleeved on the outer surface of the push rods 234.

[0050] like Figure 7 , Figure 8 and Figure 9 As shown, the mating assembly 24 includes a mounting bracket 241. A first cylinder 242 is fixedly connected to one side of the inner bottom wall of the mounting bracket 241. An optical fiber plug 243 is fixedly connected to the output end of the first cylinder 242. A first mounting seat is fixedly connected to the optical fiber plug 243. The first mounting seat is slidably connected to the mounting bracket 241. The operation of the first cylinder 242 can push the optical fiber plug 243 to move linearly, so that the optical fiber plug 243 can be accurately mated with the product under test 7.

[0051] A second cylinder 244 is fixedly connected to the other side of the inner bottom wall of the mounting bracket 241. A light guide column 245 is fixedly connected to the output end of the second cylinder 244. A second mounting seat is fixedly connected to the bottom of the light guide column 245. The second mounting seat is slidably connected to the mounting bracket 241. The operation of the second cylinder 244 can drive the light guide column 245 to move, so that the light guide column 245 can be stably connected to the optical interface of the product under test 7, thereby improving the accuracy of optical signal acquisition.

[0052] Multiple optical modules 246 are fixedly connected to the center of the mounting bracket 241. The bottom of each optical module 246 is slidably connected to the mounting bracket 241 via mounting parts. The mounting parts at the bottom of the optical modules 246 are fixedly connected to the output end of the second cylinder 244. The operation of the second cylinder 244 can synchronously drive the multiple optical modules 246 and the light guide column 245 to move and dock with the detection interface of the product under test 7, thus solving the problem of signal acquisition error caused by manual adjustment.

[0053] In other embodiments, a third cylinder is also fixedly connected to the mounting bracket 241. The output end of the third cylinder is connected to the mounting component at the bottom of the optical module 246. The third cylinder can drive multiple optical modules 246 to operate synchronously, enabling the optical module 246 to interface with the detection interface of the product under test 7.

[0054] A push-pull rod 247 is fixedly connected to the inner top wall of the mounting bracket 241. The operator can manually pull the push-pull rod 247 to move the mounting bracket 241, so that the mating assembly 24 moves closer to the product under test 7.

[0055] like Figure 10 As shown, the carrier plate assembly 25 includes a floating plate 251, which is slidably connected to the top of the base plate 21. The carrier plate 253 is fixedly connected to the top of the floating plate 251. The product to be tested 7 is placed on the top of the floating plate 251 and the carrier plate 253. Two quick clamps 3 are symmetrically fixedly connected to both sides of the top of the floating plate 251.

[0056] Both sides of the top of the floating plate 251 are fixedly connected to the stop block 252. The stop block 252 has a through hole in the middle, and the push rod 234 is slidably connected in the through hole.

[0057] When the drive assembly 22 moves the motion assembly 23 and the mating assembly 24 toward the carrier assembly 25, the push rod 234 slides in the through hole of the stop block 252. After the limit ring 235 abuts against the stop block 252, the drive assembly 22 continues to move, which can push the carrier assembly 25 closer to the back plate assembly 4, and make the test end of the product under test 7 automatically mat with the test position 42 on the back plate assembly 4. After the product under test 7 and the test position 42 are mated in place, the first cylinder 242 and the second cylinder 244 automatically extend to complete the corresponding mating action.

[0058] like Figure 11 As shown, the backplane assembly 4 includes a backplane 41, on which test position 42, CPU test position 43 and power test position 44 are respectively provided. Test position 42 is used to directly connect to the product under test 7, CPU test position 43 supports CPU board function verification, and power test position 44 provides stable power supply access.

[0059] In this embodiment, as Figure 1 As shown, a protective frame 5 is fixedly connected to the top of the lower housing 1. The protective frame 5 is set around the test mechanism 2 and the back plate assembly 4. Safety light curtains can also be installed on both sides of the entrance of the protective frame 5. This setting can effectively isolate the operating area from the moving parts, prevent accidental contact from causing personal injury or equipment damage, and improve the safety of the testing process.

[0060] In this embodiment, as Figure 1 As shown, the bottom of the lower housing 1 is fixedly connected to a cabinet 6, which is used to accommodate control lines and facilitates the organization of the lines.

[0061] In this invention, the product under test 7 is one of a CPU board, a DI board, or an OPT board.

[0062] The operator places the product to be tested 7 on the floating plate 251 and the carrier plate 253, and manually presses down the quick clamp 3 to fix it firmly.

[0063] After the device is started, the control unit issues a command, the drive component 22 starts to work, the servo motor 222 runs, and through the cooperation of the ball screw 224 and the ball nut 225, the rotational motion is converted into linear motion, thereby driving the motion component 23 to move as a whole toward the carrier plate component 25.

[0064] During the forward movement of the motion component 23, the push rod 234 slides in the through hole of the stop block 252. When the limiting ring 235 on the push rod 234 abuts against the stop block 252, the power provided by the drive component 22 will be converted into pushing the entire carrier plate assembly 25 and the product under test 7 on it to move together toward the back plate assembly 4 until the interface of the product under test 7 and the test position 42 on the back plate assembly 4 are electrically connected.

[0065] After the product under test 7 and the test position 42 are properly connected, the first cylinder 242 operates to push the fiber optic plug 243 to connect with the fiber optic interface of the product under test 7, thus completing the optical path connection.

[0066] The second cylinder 244 operates, which on the one hand pushes the light guide column 245 close to the LED indicator of the product under test to collect light signals; on the other hand, it simultaneously drives multiple light modules 246 to connect with the corresponding detection interface of the product.

[0067] Subsequently, it automatically performs preset tests such as electrical performance, optical communication signals, LED brightness and color analysis;

[0068] After the test is completed, all actuators are reset in reverse order;

[0069] Finally, the operator opens quick clamp 3 to remove the tested product.

[0070] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0071] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
