Description

Technical Field

[0001] This utility model relates to the field of electronic and electrical technology, and in particular to an electrical testing device. Background Technology

[0002] Electronic components are the basic elements in electronic circuits. They are usually individually packaged and have two or more leads or metal contacts. They are commonly used inside electrical appliances, radios, instruments, etc. Testing the electrical performance of electronic components is a very important part of testing electronic and electrical components.

[0003] An examination of application number 202420621101.X reveals an electronic and electrical testing device, including an operating table and a detection component disposed on the upper surface of the operating table. The detection component includes a track, a motor, a connecting shaft, and a rotary table. The track is fixedly connected to the upper surface of the operating table, and the motor is mounted on the lower surface of the operating table. The end of the motor's output shaft is fixedly connected to the connecting shaft. The rotary table can be rotated by the motor, thereby causing the detection groove at the end of the elastic telescopic arm to roll on the upper surface of the track, reducing the failure rate and maintenance costs of the device. Furthermore, by pulling the handle, the telescopic and push plates can be used to fix the workpiece, improving the worker's work efficiency.

[0004] The aforementioned application document describes a device that uses a motor to drive a rotary table to rotate, which in turn causes the detection slot at the end of the elastic telescopic arm to roll on the surface of the track. This reduces the failure rate and maintenance costs of the device. By pulling the handle, the telescopic and push plates can be used to fix the workpiece, improving the efficiency of the workers. However, after the electronic components have been tested, the workers still need to manually remove them from the detection slot. For electronic components that fail the test, manual intervention is required for sorting, which affects the efficiency of the work.

[0005] Therefore, it is necessary to provide a new electrical testing device to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides an electrical testing device.

[0007] The electrical testing device provided by this utility model includes: a tester body, a positioning clamp, a clamping assembly, a support plate, and a feeding assembly. The tester body is equipped with a detection assembly and a rotating table. The top of the rotating table is provided with positioning clamps at equal intervals for fixing the component to be tested. A clamping assembly is installed between the tester body and the positioning clamp. The clamping assembly drives the positioning clamp to move closer to the component to be tested for fixing it. The rotating table is equipped with support plates at equal intervals corresponding to the positioning clamps. The feeding assembly is installed between the tester body and the support plate. The feeding assembly drives the support plate to move to remove the tested component from the rotating table.

[0008] Preferably, the clamping assembly includes: an arc-shaped block, a top rod, and a connecting plate. A placement shell corresponding to the positioning clamp is fixedly connected to the top of the rotating platform at equal intervals around its circumference. Slide grooves are provided on both sides of the placement shells, and a connecting plate is slidably connected inside the slide grooves. Guide rods are symmetrically fixedly connected to the side walls of the positioning clamp. The other end of each guide rod passes through and is slidably connected to the connecting plate. A spring is fitted onto the outer wall of each guide rod. One end of each spring is fixedly connected to the corresponding positioning clamp, and the other end is fixedly connected to the corresponding connecting plate. A top rod is fixedly connected to the side of the connecting plate away from the positioning clamp. An arc-shaped block is fixedly connected to the middle of the tester body, and the arc-shaped block cooperates with several of the top rods.

[0009] Preferably, both ends of the connecting plate are fixedly connected to sliding rods, both sides of the housing are fixedly connected to mounting blocks, the other end of each sliding rod is placed inside the corresponding mounting block and slidably connected to its inner wall, and the outer wall of each sliding rod is fitted with a second spring, one end of the second spring is fixedly connected to the corresponding mounting block, and the other end is fixedly connected to the end of the corresponding connecting plate.

[0010] Preferably, the rotating platform has equidistant placement slots around its inner circumference, and several of the bearing plates are placed in the corresponding placement slots and are slidably connected to their inner walls.

[0011] Preferably, the feeding assembly includes: an electric push rod and a push plate. A mounting frame is fixedly connected to the bottom side wall of the tester body, and an electric push rod is symmetrically fixedly connected to the top of the mounting frame. Each of the electric push rods is fixedly connected to a push plate at its output end, and the two electric push rods correspond to the positions of two adjacent bearing plates.

[0012] Preferably, each of the bearing plates has a vertical rod fixedly connected to the bottom of the end near the push plate, and each of the bearing plates has a tension spring fixedly connected symmetrically to the end near the push plate. The other end of each tension spring is fixedly connected to the inner wall of the corresponding placement groove. Each of the bearing plates has a discharge port on the inner end near the vertical rod.

[0013] Preferably, a conveyor belt is symmetrically placed at the bottom of the tester body, and a guide plate is fixedly connected to the side wall of the conveyor belt near the feeding end, and the top of the guide plate corresponds to the position of the push plate.

[0014] Compared with related technologies, the electrical testing device provided by this utility model has the following advantages: With the design of the clamping assembly, the operator only needs to place the electronic component to be tested into the housing. As the component rotates with the rotating table, the clamping assembly automatically starts. Through the cooperation of the top rod and the arc block, as well as the elastic action of spring one and spring two, the positioning clamping plate can flexibly clamp and fix the electronic component. There is no need to manually fix each component one by one, which greatly reduces the manual operation steps and improves work efficiency. The design of the unloading component enables automatic sorting and unloading of qualified and unqualified components. When the tested component rotates to the corresponding unloading station, the electric push rod is activated, and the push plate pushes the vertical rod to slide the bearing plate. The component falls from the unloading port to the corresponding guide plate, and is then transported by the conveyor belt to the subsequent process or waste collection area. No manual sorting is required, which further improves work efficiency and reduces labor costs. After the first component is inspected, the rotary table continues to rotate, and the next component to be inspected moves to the inspection station with the rotary table, repeating the process of "top rod contacting arc block - positioning clamping plate clamping". This achieves continuous material supply to the inspection station, ensuring that the inspection process is uninterrupted. It can quickly and continuously inspect multiple components, greatly shortening the overall inspection time and improving inspection efficiency. Attached Figure Description

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] Please see Figures 1 to 7 An electrical testing device includes: a testing instrument body 1, a positioning clamp 4, a clamping assembly, a support plate 5, and a feeding assembly. The testing instrument body 1 houses a detection assembly 2 and a rotating table 3. The top of the rotating table 3 is equidistantly provided with positioning clamps 4 for fixing components to be tested. A clamping assembly is installed between the testing instrument body 1 and the positioning clamp 4, driving the positioning clamp 4 towards the component to be tested for fixing it. The rotating table 3 has support plates 5 equidistantly installed inside, corresponding to the positioning clamp 4. A feeding assembly is installed between the testing instrument body 1 and the support plate 5, driving the support plate 5 to move and remove the tested component from the rotating table 3.

[0020] The clamping assembly includes an arc-shaped block 6, a top rod 7, and a connecting plate 8. The top of the rotating platform 3 is equidistantly connected to a placement shell 9 corresponding to the positioning clamping plate 4. Both sides of the placement shell 9 are provided with sliding grooves, and the connecting plate 8 is slidably connected inside the sliding grooves. The side walls of the positioning clamping plate 4 are symmetrically connected to guide rods 10. The other end of each guide rod 10 passes through the connecting plate 8 and is slidably connected to it. The outer wall of each guide rod 10 is fitted with a spring 11. One end of the spring 11 is fixedly connected to the corresponding positioning clamping plate 4, and the other end is fixedly connected to the corresponding connecting plate 8. The side of the connecting plate 8 away from the positioning clamping plate 4 is fixedly connected to a top rod 7. The middle of the tester body 1 is fixedly connected to an arc-shaped block 6, and the arc-shaped block 6 cooperates with several of the top rods 7.

[0021] Both ends of the connecting plate 8 are fixedly connected to slide rods 12, and both sides of the housing 9 are fixedly connected to mounting blocks. The other end of each slide rod 12 is placed inside the corresponding mounting block and is slidably connected to its inner wall. The outer wall of each slide rod 12 is fitted with a second spring 13. One end of the second spring 13 is fixedly connected to the corresponding mounting block, and the other end is fixedly connected to the end of the corresponding connecting plate 8.

[0022] The rotating platform 3 has equidistant placement slots around its interior circumference, and several of the bearing plates 5 are placed in the corresponding placement slots and are slidably connected to their inner walls.

[0023] The feeding assembly includes an electric push rod 14 and a push plate 15. A mounting frame is fixedly connected to the bottom side wall of the tester body 1. The top of the mounting frame is symmetrically fixedly connected to the electric push rod 14. The output end of each push rod is fixedly connected to the push plate 15. The two electric push rods 14 correspond to the positions of two adjacent bearing plates 5.

[0024] Vertical rods 16 are fixedly connected to the bottom of the bearing plate 5 near the push plate 15. Tension springs 17 are symmetrically fixedly connected to the end of the bearing plate 5 near the push plate 15. The other end of the tension springs 17 is fixedly connected to the inner wall of the corresponding placement groove. A discharge port 18 is opened inside the bearing plate 5 near the vertical rod 16.

[0025] The bottom of the tester body 1 is symmetrically equipped with conveyor belts 19. The side walls of the conveyor belts 19 near the feeding end are fixedly connected with guide plates 20, and the top of the guide plates 20 corresponds to the position of the push plate 15.

[0026] It should be noted that the specific working principle of detection component 2 is as follows: Based on a preset program according to the component type (e.g., resistor, capacitor, diode, etc.), the robotic arm of detection component 2 moves the detection probe downwards until the probe precisely contacts the metal pins or test contacts of the component, establishing a stable electrical connection circuit. Next, the internal test module of detection component 2 is activated, applying a specific test signal (e.g., DC voltage, AC signal, etc.) to the component. The signal acquisition unit captures the component's feedback data in real time, including but not limited to core electrical parameters such as resistance value, capacitance, rated current, and breakdown voltage. During the measurement process, the data sampling frequency can reach millisecond levels, ensuring the timeliness and completeness of parameter capture. The acquired raw data is filtered and amplified by the signal processing module inside detection component 2, then converted into a digital signal and transmitted to the control system of the test instrument body 1. The control system compares the measured data with a preset acceptable standard range. If all parameters are within the standard, it is judged as "acceptable"; if any parameter exceeds the threshold, it is judged as "unacceptable." The judgment result is generated within 1 second.

[0027] The working principle of the electrical testing device provided by this utility model is as follows: The operator places a single electronic component to be tested in the placement shell 9 on the top of the rotating table 3, which is directly opposite the testing component 2. The component falls directly onto the top surface of the support plate 5, completing the loading of the first component. Then, the tester body 1 is started, and its internal drive motor starts to run, driving the rotating table 3 to rotate at a preset angle. When the rotating table 3 rotates to the next empty placement shell 9 and aligns with the loading position, the drive motor stops, and the operator repeats the above loading action to place the second component to be tested into the placement shell 9. After that, the rotating table 3 completes the loading of one placement shell 9 by rotating a preset angle and pausing once, until the components that need to be continuously tested have completed the initial loading. As the first electronic component is loaded and rotates with the rotary table 3, gradually approaching the detection station corresponding to the detection assembly 2, the clamping assembly starts and completes the positioning and fixing of the component. The specific process is as follows: As the rotating platform 3 continues to rotate, the top rod 7 fixed on the connecting plate 8 inside the housing 9 begins to contact the edge arc surface of the arc block 6 fixed in the middle of the tester body 1. Since the arc block 6 is a fixed arc structure, the top rod 7 will be subjected to lateral extrusion force from the arc surface of the arc block 6 when the rotating platform 3 rotates. Under the extrusion force, the top rod 7 moves towards the inside of the housing 9, thereby pushing the connecting plate 8 fixedly connected to it to move synchronously. The two ends of the connecting plate 8 are slidably connected to the mounting blocks on both sides of the housing 9 through the slide rod 12. Therefore, the connecting plate 8 makes a stable linear motion along the slide groove. During the movement, the slide rod 12 retracts into the mounting block, and at the same time compresses the spring 13 sleeved on the outer wall of the slide rod 12. The spring 13 generates elastic deformation and stores reset potential energy. When the connecting plate 8 moves, it slides with the guide rod 10, causing the positioning clamping plate 4 to move closer to the electronic component at the center of the housing 9. When the inner wall of the positioning clamping plate 4 contacts the side wall of the electronic component, the component generates a reaction force on the positioning clamping plate 4, causing the guide rod 10 to slide relative to the guide rod 10 in the through hole of the connecting plate 8, while compressing the spring 11 sleeved on the guide rod 10. The elastic force of the spring 11 is transmitted to the surface of the component through the positioning clamping plate 4, forming a flexible clamping force to avoid rigid compression that could damage the component. When the top rod 7 moves to the highest point of the middle of the arc block 6, the connecting plate 8 and the positioning clamp 4 reach their maximum stroke. At this time, the positioning clamp 4 firmly fixes the electronic component in the center of the placement shell 9, ensuring that the component does not shift during the testing process. The drive motor inside the tester body 1 stops running, the rotating table 3 stops precisely at the testing station, and the electronic component is facing the testing end of the testing component 2. After the rotating stage 3 comes to a stop, the detection component 2 inside the tester body 1 starts working; according to the detection requirements of the component, the detection probe of the detection component 2 moves downward to contact the pin of the component and establish an electrical connection; the detection component 2 accurately measures the electrical parameters of the electronic component according to the preset test program, and the measurement data is transmitted in real time to the control system inside the tester body 1 for analysis and processing. The control system compares and analyzes the test data according to the preset pass / fail criteria, quickly determines whether the component is "pass" or "fail", and stores the result in the equipment database at the same time. It also sends a pre-instruction to the corresponding unloading component. After the first component is tested, the tester body 1 controls the drive motor to start again, driving the rotating table 3 to continue rotating; at this time, the placement shell 9 where the first component is located moves away from the testing station along with the rotating table 3, and the push rod 7 gradually gets away from the squeezing action of the arc block 6; Spring 13 first releases its stored elastic potential energy, pushing the connecting plate 8 to move outward from the placement shell 9, and the slide rod 12 extends out of the mounting block to reset; at the same time, spring 11 also releases its elastic force, driving the positioning clamp 4 to move away from the component, the guide rod 10 slides to reset in the connecting plate 8, and the positioning clamp 4 completely releases its clamp on the detected component and returns to the open state. Synchronous with the transfer of the first component, the next component to be tested that has been loaded moves to the testing station with the rotating table 3, repeating the above process of "top rod 7 contacting arc block 6 - positioning clamp 4 clamping", so as to realize continuous material supply at the testing station and ensure that the testing process is uninterrupted. Based on the test result of the first component, the control system of the tester body 1 sends an action command to the corresponding electric push rod 14. The two electric push rods 14 correspond to the "qualified component unloading station" and the "unqualified component unloading station" respectively. The specific diversion process is as follows: If the test result is qualified, when the tested component rotates with the rotating table 3 to the "qualified component unloading station", the electric push rod 14 corresponding to the station is activated, its output end extends, and drives the push plate 15 to move towards the vertical rod 16 at the bottom of the support plate 5; after the push plate 15 contacts the vertical rod 16, it continues to apply a pushing force, which drives the vertical rod 16 and the support plate 5 fixed to it to slide to the outside of the placement groove. During the sliding process of the support plate 5, the tension springs 17 on both sides are stretched, and the tension springs 17 generate a reset tension force. When the support plate 5 slides outward, the discharge port 18 on its top surface gradually moves to directly below the electronic component. When the support plate 5 slides to its maximum stroke, the discharge port 18 is completely aligned with the component position. The component loses its support and falls vertically from the discharge port 18. The qualified component falls directly into the corresponding guide plate 20 below. The guide plate 20 is designed to be inclined. The component slides along the inclined surface of the guide plate 20 to the conveyor belt 19 below. The conveyor belt 19 then transports the qualified component to the subsequent packaging or assembly process. After the components are unloaded, the electric push rod 14 receives a reset signal and retracts its output end, causing the push plate 15 to move away from the vertical rod 16. Under the tension of the tension spring 17, the bearing plate 5 slides back to its initial storage position along the placement groove, waiting for the next component to be carried. If the test result is unqualified, when the tested component rotates with the rotary table 3 to the "qualified component unloading station", the electric push rod 14 of the station remains in the retracted state and does not perform the unloading action. The component continues to rotate with the rotary table 3. When the rotary table 3 drives the unqualified component to the "unqualified component unloading station", the electric push rod 14 corresponding to the station is activated. Its action process is completely consistent with the unloading of qualified components: the output end of the electric push rod 14 extends to drive the push plate 15 to push the vertical rod 16, the bearing plate 5 slides outward and stretches the tension spring 17, the unloading port 18 moves to the bottom of the component to make it fall, and the unqualified component slides into the dedicated unqualified product conveyor belt 19 through the corresponding guide plate 20 and is transported to the waste collection box or rework area to achieve complete separation from qualified components. After the material is unloaded, the electric push rod 14 of this station retracts and resets, and the bearing plate 5 returns to its initial position under the action of the tension spring 17; After the first component is unloaded, the rotating table 3 continues to rotate cyclically at a preset angle. Subsequent components to be tested undergo the complete process of "positioning and clamping - testing - sorting and unloading" in sequence. At the same time, the operator continuously replenishes the components to be tested into the empty placement shell 9, enabling the device to perform continuous and uninterrupted batch testing. When all components have been tested, the control instrument body 1 stops, the drive motor stops, and all components are reset to their initial state under the action of the control system, waiting for the next batch of testing tasks.
