Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board testing technology, specifically the TR5001E high-precision testing equipment. Background Technology
[0002] The development background of the TR5001E high-precision testing equipment stems from the urgent need of the electronics manufacturing industry for the accuracy and efficiency of printed circuit board testing. As electronic components develop towards miniaturization and integration, traditional manual testing or simple functional testing can no longer meet the defect location requirements of complex circuits.
[0003] The probe plays a crucial role in the testing equipment by contacting the component under test and conducting electrical signals. When the probe is exposed to air for a long time, the metal surface is prone to react with oxygen to form an oxide film, which is far beyond the normal contact resistance. This will cause the test current or voltage signal to attenuate, resulting in misjudgment of continuity or deviation in component parameter measurement. In addition, the oxide layer will aggravate the mechanical wear when the probe contacts the component under test, leading to rapid wear and deformation of the probe tip. Therefore, we proposed the TR5001E high-precision testing equipment. Utility Model Content
[0004] The purpose of this invention is to provide the TR5001E high-precision testing equipment to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a TR5001E high-precision testing device, including a worktable, a support frame mounted on the top of the worktable, and further comprising:
[0006] An anti-oxidation component includes an alcohol box mounted on the top of a workbench, a connecting groove on a support frame, the alcohol box being slidably connected to the connecting groove, a rotating shaft rotatably connected to the support frame, a force transmission plate rotatably connected to the rotating shaft, and a pusher on the side of the force transmission plate near the alcohol box.
[0007] A drive assembly includes a fixed plate connected to a support frame, an electric push rod is provided on the fixed plate, the output end of the electric push rod is connected to a connecting rod, and the connecting rod is connected to a force transmission plate.
[0008] Furthermore, the support frame is provided with a spring-loaded assembly, which includes an extension plate. The alcohol box is provided with a support plate, and a spring connects the extension plate and the support plate.
[0009] The above technical solution involves setting up a rebound component to restore the alcohol box after the probe has been soaked to its original position, thus preventing obstruction of the detection path.
[0010] Furthermore, a detection component is provided on the support frame, the detection component including a hydraulic cylinder disposed on the top of the support frame, and a probe is connected to the output end of the hydraulic cylinder.
[0011] The above technical solution involves setting up a detection component and using probes to detect the circuit board.
[0012] Furthermore, a display component is provided on the support frame, the display component includes a display screen, a connecting frame is connected to the support frame, and the display screen is connected to the connecting frame.
[0013] The above technical solution involves setting up a display component to present the detected data on a screen.
[0014] Furthermore, a fixing component is provided on the top of the workbench, the fixing component includes a clamping plate, and a sliding groove is provided on the side of the top of the workbench near the clamping plate. A limiting block is slidably connected on the sliding groove, and the limiting block is connected to the clamping plate.
[0015] The above technical solution involves setting up a fixing component to clamp and limit the circuit board, preventing it from shaking during the testing process.
[0016] Furthermore, an adjustment assembly is provided on the top of the workbench near the clamping plate. The adjustment assembly includes a slide rail, a lead screw is rotatably connected to the slide rail, a sliding block is threaded onto the lead screw, and a connecting piece is connected between the sliding block and the clamping plate.
[0017] The above technical solution involves setting up an adjustment component to adjust the distance between the two clamping plates for circuit boards of different sizes, thereby adapting to different circuit boards.
[0018] Furthermore, a housing is provided on the slide rail, and a motor is provided inside the housing. The lead screw is connected to the output end of the motor, and two sliding blocks are provided, with the two sliding blocks threaded onto the lead screw in opposite directions.
[0019] The above technical solution involves setting up a motor as the power source for the lead screw rotation, thereby driving the lead screw to rotate.
[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0021] In this invention, by setting an anti-oxidation component, the metal surface of the probe is prevented from reacting with oxygen to form an oxide film, thus avoiding misjudgment of continuity due to signal attenuation. This solves the problem that the probe plays a crucial role in the testing equipment by contacting the component under test and conducting electrical signals. When the probe is exposed to air for a long time, the metal surface of the probe is prone to react with oxygen to form an oxide film, which is far beyond the normal contact resistance. This will lead to attenuation of the test current or voltage signal, causing misjudgment of continuity or deviation in component parameter measurement. In addition, the oxide layer will aggravate the mechanical wear when the probe contacts the component under test, leading to rapid wear and deformation of the probe tip. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0037] like Figures 1-5 As shown, this utility model provides a technical solution: a TR5001E high-precision testing device, including a workbench 1, a support frame 2 mounted on the top of the workbench 1, and further comprising:
[0038] Anti-oxidation component 3 includes an alcohol box 31 set on the top of the workbench 1, a connecting groove 32 opened on the support frame 2, the alcohol box 31 is slidably connected to the connecting groove 32, a rotating shaft 34 is rotatably connected to the support frame 2, a force transmission plate 33 is rotatably connected to the rotating shaft 34, and a push head 35 is provided on the side of the force transmission plate 33 near the alcohol box 31.
[0039] Drive assembly 6 includes a fixed plate 61 connected to the support frame 2, an electric push rod 62 is provided on the fixed plate 61, the output end of the electric push rod 62 is connected to a connecting rod 63, and the connecting rod 63 is connected to the force transmission plate 33.
[0040] The support frame 2 is equipped with a detection component 9, which includes a hydraulic cylinder 91 located on the top of the support frame 2, and a probe 92 connected to the output end of the hydraulic cylinder 91.
[0041] Specifically, firstly, the electric push rod 62 is activated to drive the connecting rod 63 to move. The connecting rod 63 drives the force transmission plate 33 to rotate through the rotating shaft 34. During the rotation, the force transmission plate 33 drives the push head 35 at the bottom to apply a pushing force to the alcohol box 31, thereby sliding the alcohol box 31 in the connecting groove 32 and pushing it directly below the probe 92. Then, the hydraulic cylinder 91 is activated to drive the probe 92 to descend, so that it is immersed in the alcohol box 31 for deoxidation.
[0042] Furthermore, such as Figure 1 As shown: A fixing component 7 is provided on the top of the workbench 1. The fixing component 7 includes a clamping plate 71. A slide groove 72 is provided on the side of the top of the workbench 1 near the clamping plate 71. A limit block 73 is slidably connected on the slide groove 72. The limit block 73 is connected to the clamping plate 71. The circuit board is placed on the top of the workbench 1, and then the clamping plate 71 is slid on the slide groove 72 through the limit block 73 until the circuit board is clamped and limited.
[0043] The above solution also has the problem that the alcohol box 31 cannot automatically reset after the deoxidation process, which will block the detection path, such as... Figure 2 As shown: A spring-loaded assembly 4 is provided on the support frame 2. The spring-loaded assembly 4 includes an extension plate 41. A support plate 42 is provided on the alcohol box 31. A spring 43 is connected between the extension plate 41 and the support plate 42. After the deoxidation work is completed, when the pusher 35 separates from the alcohol box 31, the alcohol box 31 automatically resets due to the elastic force of the spring 43.
[0044] The above solutions also have the problem that, due to the different sizes of circuit boards, the fixing clamp 71 cannot be adapted to different circuit boards, such as... Figure 1 As shown: An adjustment component 8 is provided on the top side of the workbench 1 near the clamping plate 71. The adjustment component 8 includes a slide rail 81, a lead screw 82 rotatably connected to the slide rail 81, a sliding block 83 threadedly connected to the lead screw 82, and a connector 85 connecting the sliding block 83 and the clamping plate 71. A housing 84 is provided on the slide rail 81, and a motor is provided inside the housing 84. The lead screw 82 is connected to the output end of the motor. There are two sliding blocks 83, and the two sliding blocks 83 are threaded in opposite directions on the lead screw 82. When the motor is turned on, the lead screw 82 is driven to rotate in the slide rail 81. The lead screw 82 drives the sliding block 83 to slide in the slide rail 81, thereby driving the clamping plate 71 to move through the connector 85, and clamping circuit boards of different sizes.
[0045] Furthermore, such as Figure 2 As shown: A display component 5 is provided on the support frame 2. The display component 5 includes a display screen 51. A connecting frame 52 is connected to the support frame 2. The display screen 51 is connected to the connecting frame 52. By setting the display component 5, the detected data is displayed on the display screen 51.
[0046] The working principle provided by this utility model is as follows: Figures 1-5 As shown: First, the circuit board is placed on top of the workbench 1. The motor is turned on to drive the lead screw 82 to rotate in the slide rail 81. The lead screw 82 drives the sliding block 83 to slide in the slide rail 81, thereby moving the clamping plate 71 through the connecting piece 85 to clamp circuit boards of different sizes. Then, the hydraulic cylinder 91 is turned on to drive the probe 92 to descend until it contacts the circuit board for detection. The detection result is displayed on the display screen 51. When the probe 92 shows oxidation, the electric push rod 62 is turned on to drive the connecting rod 63 to move. The connecting rod 63 drives the force transmission plate 33 to rotate through the rotating shaft 34. During the rotation, the force transmission plate 33 will drive the push head 35 at the bottom to apply a pushing force to the alcohol box 31, thereby sliding the alcohol box 31 in the connecting groove 32 and pushing it directly below the probe 92. Then, the hydraulic cylinder 91 is turned on to drive the probe 92 to descend, immersing it in the alcohol box 31 for deoxidation. After the deoxidation is completed, when the push head 35 separates from the alcohol box 31, the alcohol box 31 automatically resets due to the elastic force of the spring 43.
