Abstract
Description
Technical Field
[0001] This invention relates to the field of electronic equipment testing technology, and in particular to an electronic equipment testing device and its working method. Background Technology
[0002] With the miniaturization and integration of electronic devices, circuit boards and functional modules need to undergo electrical testing with probes before leaving the factory, which places higher demands on the positioning accuracy, clamping versatility and pressure protection of the devices.
[0003] A search revealed that Chinese patent CN219832162U discloses a pressure point screen device and a display panel testing device. This patent uses a lifting mechanism to drive a probe to complete contact testing, which can realize basic electrical testing functions.
[0004] Although the aforementioned crimping screen device and display panel testing device can drive the probe through the lifting mechanism to achieve basic electrical testing functions, their clamping structure cannot quickly adjust the width, resulting in a narrow range of compatibility with devices of different sizes. Furthermore, the probe is only rigidly pressed down by a cylinder without pressure feedback or buffer protection structures, which can easily damage precision electronic components during testing. This makes the device's versatility, testing stability, and ease of maintenance all poor. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides an electronic device detection apparatus and its operating method, which solves the problems mentioned in the background section.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An electronic device testing apparatus includes a support platform, a testing component, and a clamping component. The testing component includes a support frame fixedly mounted on the top of the support platform. A first sleeve block is movably mounted inside the support frame. A cylinder is fixedly mounted on the bottom of the first sleeve block. A fixing sleeve is fixedly mounted on the bottom of the cylinder. A fixing plate is movably mounted inside the fixing sleeve. A spring is installed between the fixing plate and the fixing sleeve. A pressure sensor is fixedly mounted inside the fixing sleeve. A probe is fixedly mounted on the bottom of the fixing plate. A screw is threaded into the inside of the first sleeve block. A drive component is fixedly mounted at one end of the screw. A control panel is fixedly mounted on the front of the support platform and is electrically connected to the probe. A support component is fixedly mounted on the bottom of the support platform.
[0008] Furthermore, the clamping assembly includes two second sleeve blocks movably installed inside the support platform, and the two second sleeve blocks are threaded with bidirectional screws. A rotating disk is fixedly installed at one end of the bidirectional screw, and a rotating handle is fixedly installed on the outer surface of the rotating disk. A movable frame is fixedly installed on the top of each of the two second sleeve blocks. An installation plate is movably installed inside the movable frame. A clamping plate is fixedly installed on the inner side of the installation plate. A rubber pad is fixedly installed on the inner side of the clamping plate. A placement plate is fixedly installed on the top of the support platform, and a disassembly assembly is provided on the top of the installation plate.
[0009] Furthermore, the drive assembly includes a driven gear fixedly mounted on one end of the screw, a motor fixedly mounted on the right side of the support platform, a drive gear fixedly mounted on the output end of the motor, and the drive gear meshes with the driven gear.
[0010] Furthermore, the assembly and disassembly assembly includes a first positioning post fixedly installed on the top of the mounting plate, a second positioning post fixedly installed on the top of the movable frame, a limiting member movably installed on the outer surface of the second positioning post, and a groove at one end of the limiting member engaging with the outer side of the first positioning post.
[0011] Furthermore, the support assembly includes four columns fixedly installed at the bottom of the support platform, and a base is fixedly installed at the bottom of each column.
[0012] Furthermore, a support base is fixedly installed at the bottom of the support frame, and the support base fits against the outer surface of the motor through its internal groove.
[0013] Furthermore, the movable frame is provided with a dovetail groove, the mounting plate is provided with a dovetail that can be inserted into the dovetail groove, a clamping plate is fixedly installed on the part of the dovetail that protrudes from the dovetail groove, and the first positioning post is fixedly installed on the dovetail.
[0014] The working method of the electronic device testing device of the present invention is characterized in that the electronic device to be tested is first placed on the placement plate on the top of the support platform, and the rotating handle on the outer surface of the rotating disk is rotated to drive the bidirectional screw to rotate, so that the two second sets of blocks inside the support platform move relative to each other, thereby driving the moving frame and the clamping plate to move closer to the device, and the rubber pad achieves stable clamping to avoid the electrical equipment from shifting during testing.
[0015] Then, operate the control panel to start the motor. The drive gear at the motor output end drives the driven gear to rotate, causing the screw to rotate and drive the first block to move inside the support frame. Adjust the probe to the detection position. The support base fixes the motor through the internal groove to ensure stable operation.
[0016] Next, the cylinder is activated to push the fixed sleeve down, so that the probe contacts the detection point of the equipment. The fixed plate compresses the spring, and the pressure sensor detects the contact pressure to prevent excessive pressure from damaging the equipment. The probe transmits the detection signal to the control panel to complete the detection and display the result.
[0017] Furthermore, when it is necessary to change the mounting plate according to the size of different products to be clamped, the thickness of the clamping plate is different for different products to be clamped. The groove of the limiting member is disengaged from the limiting of the first positioning post, and then the dovetail of the mounting plate is pulled out from the dovetail groove. Another mounting plate with the same dovetail is inserted and replaced. Then the groove of the limiting member is re-clamped into the first positioning post, thereby achieving relative fixation between the mounting plate and the moving frame.
[0018] Compared with existing technologies, the advantages of this invention are:
[0019] 1. By rotating the handle, the two clamping plates can be moved synchronously relative to each other. The rubber pads can prevent damage to the surface of the equipment during clamping and can be adapted to electronic equipment of different sizes and specifications. There is no need to replace the special clamps, which expands the applicability of the device, reduces the adaptation cost of equipment testing, and improves the versatility and practicality of the device.
[0020] 2. By using a pressure sensor in conjunction with a spring, the contact pressure between the probe and the equipment is monitored in real time. This prevents excessive pressure from damaging the electronic equipment or the probe, while also preventing insufficient pressure from causing poor contact and inaccurate test data. This ensures the accuracy of the test results, reduces equipment wear and repeated testing caused by testing errors, and improves the quality of testing.
[0021] 3. Through the coordinated action of the drive components and cylinders, the horizontal position and vertical height of the probe are precisely adjusted to ensure that the probe accurately aligns with the equipment's detection point; the support base securely supports the motor, column, and base, ensuring stable operation of the device; the components are easy to disassemble and replace the clamping parts, further improving the device's flexibility and service life, and reducing maintenance costs.

[0030] Example 1
[0031] Reference Figures 1-6 An electronic device testing device includes a support platform 1, a testing component, and a clamping component. The testing component includes a support frame 2 fixedly mounted on the top of the support platform 1. A support base 16 is fixedly mounted on the bottom of the support frame 2, and the support base 16 fits against the outer surface of a motor 15 through its internal groove. A first sleeve block 19 is movably mounted inside the support frame 2. A cylinder 4 is fixedly mounted on the bottom of the first sleeve block 19. A fixing sleeve 5 is fixedly mounted on the bottom of the cylinder 4. A fixing plate 23 is movably mounted inside the fixing sleeve 5. A spring 25 is installed between the fixing plate 23 and the fixing sleeve 5. A pressure sensor 24 is fixedly mounted inside the fixing sleeve 5.
[0032] The pressure sensor 24 is a PT124B type sensor. Its working principle is based on the piezoresistive effect. When the probe 6 contacts the device under test and generates pressure, the pressure is transmitted to the fixed plate 23, which in turn squeezes the spring 25 and acts on the pressure sensor 24, causing a slight deformation of its internal sensitive element. This converts the pressure signal into an identifiable electrical signal and feeds it back to the control panel 3, enabling real-time monitoring of the contact pressure. This avoids damage to the device or the probe 6, which is fixedly connected to the fixed plate 23, due to excessive pressure, thus ensuring the safety and accuracy of the test.
[0033] The support frame 2 at the top of the support platform 1 provides the mounting base for the detection components. The support base 16 at the bottom of the support frame 2 fits against the outer surface of the motor 15 through the internal groove to ensure stable operation. The first set of blocks 19 is movably installed inside the support frame 2. The cylinder 4 at the bottom of the first set of blocks can push the fixed sleeve 5 to rise and fall. The fixed plate 23 inside the fixed sleeve 5 cooperates with the spring 25. The pressure sensor 24 detects the force on the fixed plate 23 in real time to ensure that the probe contact pressure is reasonable during subsequent detection, thus ensuring detection safety and accuracy.
[0034] A probe 6 is fixedly installed at the bottom of the fixed plate 23. The probe 6 is a P100B1 type spring probe. The probe 6 presses down synchronously with the fixed plate 23 and contacts the detection point of the electronic device to collect the electrical signal of the device and transmit it to the control panel 3 to realize the detection of parameters such as continuity, voltage and function.
[0035] The first set of blocks 19 has a screw 20 threaded inside. A drive assembly is fixedly installed at one end of the screw 20. The drive assembly includes a driven gear 13 fixedly installed at one end of the screw 20. A motor 15 is fixedly installed on the right side of the support platform 1. The motor 15 is a Y80M1-2 servo motor. When it works, it converts electrical energy into mechanical energy based on the principle of electromagnetic induction. After the motor 15 is powered on, the stator winding in the motor 15 generates an alternating magnetic field. The rotor cuts the magnetic field lines under the action of the magnetic field force to form an electromagnetic torque, which drives the rotor to rotate. A drive gear 14 is fixedly installed at the output end of the motor 15, and the drive gear 14 meshes with the driven gear 13.
[0036] The probe 6 is fixedly installed at the bottom of the fixing plate 23. The screw 20 is threaded inside the first sleeve block 19. A drive assembly is installed at one end of the screw 20. The motor 15 fixed on the right side of the support platform 1 has a drive gear 14 installed at its output end. The drive gear 14 meshes with the driven gear 13 at one end of the screw 20. When the motor 15 runs, it drives the drive gear 14 to rotate. Through the meshing of the gear and the driven gear 13, the screw 20 rotates, thereby driving the first sleeve block 19 to move along the axial direction of the screw 20, realizing the position adjustment of the probe 6 and preparing for subsequent testing.
[0037] A control panel 3 is fixedly installed on the front of the support platform 1, and the control panel 3 is electrically connected to the probe 6. A support assembly is fixedly installed on the bottom of the support platform 1. The support assembly includes four columns 7 fixedly installed on the bottom of the support platform 1, and a base 8 is fixedly installed on the bottom of the columns 7.
[0038] A control panel 3 is fixed to the front of the support platform 1, and the control panel 3 is electrically connected to the probe 6 to transmit detection signals and control the operation of related components, ensuring the orderly conduct of the detection process. A support assembly is provided at the bottom of the support platform 1, which includes four columns 7 fixed to the bottom of the support platform 1, and a base 8 is installed at the bottom of the support assembly. The two work together to provide stable support for the entire device, prevent the device from shaking during the detection process, and ensure the accurate positioning of the probe 6 and the smooth operation of the detection work.
[0039] The clamping assembly includes two second sleeve blocks 21 movably installed inside the support platform 1, and the interior of the two second sleeve blocks 21 is threaded onto the threaded sections at both ends of the bidirectional screw 22 (the threads at both ends face opposite directions, so that when the bidirectional screw 22 rotates in one direction, the two second sleeve blocks 21 move in opposite directions). A rotating disk 17 is fixedly installed at one end of the bidirectional screw 22, and a rotating handle 18 is fixedly installed on the outer surface of the rotating disk 17. A movable frame 10 is fixedly installed on the top of each of the two second sleeve blocks 21. An installation plate 26 is movably installed inside the movable frame 10. A clamping plate 11 is fixedly installed on the inner side of the installation plate 26. A rubber pad 12 is fixedly installed on the inner side of the clamping plate 11. A placement plate 9 is fixedly installed on the top of the support platform 1.
[0040] A placement plate 9 is fixed to the top of the support platform 1 for placing the electronic device to be tested. The clamping assembly includes two second sleeve blocks 21 that are movably installed inside the support platform 1. A bidirectional screw 22 is threaded inside the second sleeve block 21. A rotating disk 17 is fixed to one end of the bidirectional screw 22. A rotating handle 18 is installed on the outer surface of the rotating disk 17. Rotating the rotating handle 18 drives the bidirectional screw 22 to rotate, which drives the two second sleeve blocks 21 to move relative to each other, thereby driving the top moving frame 10, the mounting plate 26 and the clamping plate 11 to move. The rubber pad 12 on the inner side of the clamping plate 11 achieves stable clamping of the device to be tested.
[0041] The top of the mounting plate 26 is provided with a disassembly assembly, which includes a first positioning post 27 fixedly installed on the top of the mounting plate 26, a second positioning post 28 fixedly installed on the top of the movable frame 10, a limiting member 29 rotatably connected to the outer surface of the second positioning post 28, and a groove at one end of the limiting member 29 engaging with the outer side of the first positioning post 27. Specifically, the movable frame 10 is provided with a dovetail groove, and the mounting plate 26 is provided with a dovetail that can be inserted into the dovetail groove. A clamping plate 11 is fixedly installed on the part of the dovetail that protrudes from the dovetail groove, and the first positioning post 27 is fixedly installed on the dovetail.
[0042] The mounting plate 26 is equipped with a disassembly and assembly assembly on its top to facilitate easy disassembly and assembly between the mounting plate 26 and the movable frame 10. The disassembly and assembly assembly includes a first positioning post 27 fixed to the top of the mounting plate 26 and a second positioning post 28 fixed to the top of the movable frame 10. A limiting member 29 is rotatably connected to the outer surface of the second positioning post 28. The movable frame 10 is provided with a dovetail groove, and the mounting plate 26 is provided with a dovetail that can be inserted into the dovetail groove. A clamping plate 11 is fixedly installed on the part of the dovetail that protrudes from the dovetail groove. The first positioning post 27 is fixedly installed on the dovetail. When it is necessary to change the mounting plate 26 according to the size of different products to be clamped (the thickness of the clamping plate 11 is different for different products to be clamped), the groove of the limiting member 29 is disengaged from the limiting of the first positioning post 27, and then the dovetail of the mounting plate 26 is pulled out from the dovetail groove. Another mounting plate 26 with the same dovetail is inserted, and then the groove of the limiting member 29 is re-engaged into the first positioning post 27, thereby achieving relative fixation between the mounting plate 26 and the movable frame 10.
[0043] With the above structure, the installation and removal of the mounting plate 26 can be completed quickly, adapting to different specifications of testing equipment.
[0044] In this embodiment, the electronic device to be tested is first placed on the placement plate 9 on the top of the support platform 1. The rotating handle 18 on the outer surface of the rotating disk 17 is rotated to drive the bidirectional screw 22 to rotate, so that the two second sets of blocks 21 inside the support platform 1 move relative to each other, thereby driving the moving frame 10 and the clamping plate 11 to move closer to the device. The rubber pad 12 is used to achieve stable clamping and prevent the power device from shifting during testing.
[0045] Then, operate the control panel 3 to start the motor 15. The drive gear 14 at the output end of the motor 15 drives the driven gear 13 to rotate, causing the screw 20 to rotate, driving the first block 19 to move inside the support frame 2, adjusting the probe 6 to the detection position. The support seat 16 fixes the motor 15 through the internal groove to ensure stable operation.
[0046] Next, the cylinder 4 is activated to push the fixed sleeve 5 down, so that the probe 6 contacts the detection point of the equipment. The fixed plate 23 compresses the spring 25, and the pressure sensor 24 detects the contact pressure to avoid excessive pressure from damaging the equipment. The probe 6 transmits the detection signal to the control panel 3 to complete the detection and display the result.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
