Description

Technical Field

[0001] This utility model relates to the field of electronic component testing technology, specifically to an electronic component testing device. Background Technology

[0002] Electronic components are the components of electronic parts and small machines and instruments. They are usually composed of several parts and can be used in similar products. They often refer to certain parts in industries such as electrical appliances, radio, and instruments. They are a general term for electronic devices such as capacitors, transistors, hairsprings, and clockwork. Electronic components are widely used. Before electronic components are put into use, they need to be tested for quality and performance using electronic component testing equipment.

[0003] For example, a conveniently fixed electronic component testing device with application number CN202220018815.2 includes a base, a top seat, and a testing head body. This utility model uses a vertical sliding fit between the insert and the slot and a horizontal sliding fit between the limiting rod and the limiting hole to detachably fix the top seat and the testing head body to the top of the side seat. The testing head body and the top seat can be removed from the side seat simply by pulling the limiting rod out of the limiting hole and then vertically dislodging the insert from the slot. The fixing and disassembly method of the top seat and the testing head body from the side seat is simple and easy to operate, which facilitates the quick delivery of the testing head body for inspection, repair, or calibration maintenance.

[0004] However, in the aforementioned patents, when testing electronic components, it is necessary to manually place, adjust, and test each electronic component individually. This not only increases the labor intensity of the operators but also results in low overall testing efficiency, making it difficult to meet the needs of rapid testing of large batches of electronic components. At the same time, the existing devices lack flexibility in adjusting the testing position, making it impossible to conveniently adjust the relative position of the testing head and the components according to different specifications and testing requirements. This can easily affect testing accuracy and has poor applicability.

[0005] Therefore, we propose an electronic component testing device to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide an electronic component testing device to solve the problems mentioned in the background art, which require manual placement, position adjustment and testing of electronic components one by one. This not only increases the labor intensity of operators, but also leads to low overall testing efficiency and insufficient flexibility in adjusting the testing position of the device.

[0007] This utility model provides the following technical solution: an electronic component testing device, including a testing conveyor table, on which an electronic component body is placed, a fixing component is installed on the testing conveyor table, a bracket is fixed on the testing conveyor table, a sensor is fixed on the bracket, a testing component is installed on the bracket, the testing component includes two fixing blocks fixed on the bracket, a guide rod is fixed between the two fixing blocks, an L-shaped seat slides on the guide rod, a qualified conveyor table is installed on one side of the testing conveyor table, a defective conveyor table is installed on one side of the testing conveyor table, and a pushing component is provided on the testing conveyor table.

[0008] Preferably, the fixing component includes a suction cup fixed on the detection conveyor table. The top surface of the suction cup has multiple leakage holes, the bottom surface of the suction cup is connected to a connecting pipe, the bottom of the connecting pipe is connected to a vacuum tube, the end of the vacuum tube is connected to a vacuum pump, and the vacuum pump is fixedly connected to the detection conveyor table.

[0009] Preferably, a motor is fixed to the side wall of one of the fixing blocks, a lead screw is fixed to the output end of the motor, the L-shaped seat is threaded to the lead screw, fixing plates are symmetrically fixed to both sides of the L-shaped seat, two fixing plates are provided, an electric push column is fixed to the top surface of each of the two fixing plates, a horizontal plate is fixed to the output end of the electric push column, a sliding column is fixed to the bottom surface of the horizontal plate, and limit strips are symmetrically fixed to both sides of the sliding column.

[0010] Preferably, the L-shaped seat has a notch, the sliding column is slidably connected to the notch, the inner wall of the L-shaped seat has a groove, the limiting strip is slidably connected to the groove, and a detection probe is fixed on the sliding column.

[0011] Preferably, the detection probe is connected to a wire, and a detection platform is fixed to the side wall of the detection conveyor, with the detection platform connected to the wire.

[0012] Preferably, the feeding assembly is provided in two sets. The feeding assembly includes a support base fixed on the detection conveyor table, an electric push rod fixed on the support base, and a push plate fixed at the output end of the electric push rod.

[0013] This utility model has the following beneficial effects:

[0014] 1. This device solves the problem of low efficiency caused by manual one-by-one operation in existing devices, realizing the automated operation of the entire process of electronic component transportation, positioning, detection, and sorting. It significantly reduces manual operation steps, not only reducing the error risk caused by human intervention, but also increasing the detection throughput per unit time, meeting the needs of rapid detection of large batches of electronic components, and improving detection efficiency and large-scale detection capabilities.

[0015] 2. This device effectively solves the problem of insufficient flexibility in adjusting the detection position of existing devices, and improves the positioning accuracy of the detection probe. Through the coordinated operation of multiple structures, the position of the detection probe can be adjusted and stably moved downward, adapting to electronic components of different specifications and with different detection requirements. It effectively avoids positioning deviations, ensures accurate contact between the detection probe and the pins of electronic components, lays the foundation for the accuracy of subsequent detection work, and improves the applicability of the device.

[0016] 3. After the device completes the inspection, no manual intervention is required for sorting. Through the rapid judgment and signal transmission of the inspection data by the sensor, the pushing component can promptly send qualified and unqualified products to the corresponding conveyor, which greatly shortens the sorting time. Combined with automated inspection operations, it further improves the efficiency of the overall inspection process.

[0017] 4. This device can firmly fix the electronic components at the detection position through the fixing components, effectively solving the displacement problem that is prone to occur during the detection stage and avoiding detection errors caused by displacement. Combined with the adjustment of the detection probe position, it further ensures the reliability of the detection results and improves the detection accuracy. Moreover, the negative pressure adsorption fixing method, combined with the multiple perforations on the top surface of the suction cup, can make the adsorption force evenly distributed on the surface of the component, preventing excessive local force from damaging the component. It not only replaces the manual adjustment and fixing method, but also ensures the integrity of the component after detection. Attached Figure Description

[0024] 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.

[0025] Example 1: This example aims to address the problems of insufficient positioning accuracy of the detection probe 613 and low sorting efficiency after detection in traditional electronic component testing processes. Please refer to [link to example]. Figure 1 - Figure 5 An electronic component testing device includes a testing conveyor 1 on which an electronic component body 2 is placed. A bracket 4 is fixed on the testing conveyor 1, and a sensor 5 is fixed on the bracket 4. A testing assembly 6 is mounted on the bracket 4. The testing assembly 6 includes two fixing blocks 61 fixed on the bracket 4, a guide rod 64 fixed between the two fixing blocks 61, and an L-shaped seat 65 sliding on the guide rod 64. A motor 62 is fixed to the side wall of one of the fixing blocks 61, and a lead screw 63 is fixed to the output end of the motor 62. The L-shaped seat 65 is threadedly installed with the lead screw 63. Fixing plates 66 are symmetrically fixed on both sides of the L-shaped seat 65. Two plates 66 are provided. Electric push columns 67 are fixed on the top surface of both plates 66. A horizontal plate 68 is fixed at the output end of the electric push column 67. A sliding column 69 is fixed on the bottom surface of the horizontal plate 68. Limiting strips 610 are symmetrically fixed on both sides of the sliding column 69. A notch 611 is opened on the L-shaped seat 65. The sliding column 69 is slidably connected to the notch 611. A groove 612 is opened on the inner wall of the L-shaped seat 65. The limiting strips 610 are slidably connected to the groove 612. A detection probe 613 is fixed on the sliding column 69. A wire 614 is connected to the detection probe 613. A detection table 615 is fixed on the side wall of the detection conveyor table 1. The detection table 615 is connected to the wire 614.

[0026] A qualified conveyor 7 is installed on one side of the inspection conveyor 1, and a non-qualified conveyor 8 is installed on the other side of the inspection conveyor 1. The inspection conveyor 1 is equipped with a pusher assembly 9, which has two sets. The pusher assembly 9 includes a support base 91 fixed on the inspection conveyor 1, an electric push rod 92 fixed on the support base 91, and a push plate 93 fixed at the output end of the electric push rod 92.

[0027] It should be noted that the core components of the inspection conveyor 1, the qualified conveyor 7, and the unqualified conveyor 8 in this device are identical, all assembled from conventional components such as conveyor rollers, drive motors, and belts. During operation, the drive motor provides power to rotate the conveyor rollers, which in turn drive the belts to circulate, thus achieving stable transport of the electronic component body 2. Since the aforementioned structure and working principle of the conveyor are existing mature technologies and not the main innovation of this application, they will not be described in detail here.

[0028] In this embodiment, electronic components must undergo rigorous testing before being put into use. During testing, the electronic component body 2 is first placed on the testing conveyor 1, which then moves it smoothly. When the electronic component body 2 is conveyed to the area directly below the testing probe 613, the fixing component 3 is activated to initially limit its movement, ensuring that the electronic component body 2 accurately stops at the preset testing position and preventing displacement during subsequent testing.

[0029] After positioning is completed, the detection component 6 is activated to begin detection. First, the position of the detection probe 613 needs to be adjusted according to the specific location of the pins on the electronic component body 2. During the adjustment phase, the motor 62, fixed to the side wall of one of the fixing blocks 61, is started. The motor 62 drives the lead screw 63 at its output end to rotate synchronously. Since the L-shaped seat 65 and the lead screw 63 are installed with a threaded connection, and the L-shaped seat 65 is slidably connected to the two fixing blocks 61 via the guide rod 64, the rotation of the lead screw 63 drives the L-shaped seat 65 to slide smoothly along the length of the guide rod 64, thereby causing the detection probe 613 to move synchronously until the detection probe 613 is approximately aligned with the area directly above the pins of the electronic component body 2.

[0030] Then, the electric push column 67 on the top surface of the fixed plate 66 is activated, and the electric push column 67 drives the horizontal plate 68 at its output end to move downward. During the downward movement of the horizontal plate 68, it will drive the sliding column 69 on its bottom surface to slide along the notch 611 on the L-shaped seat 65. At the same time, the limiting strips 610 on both sides of the sliding column 69 will slide synchronously along the grooves 612 on the inner wall of the L-shaped seat 65. The limiting strips 610 can effectively limit the sliding trajectory of the sliding column 69, prevent it from deviating, and ensure the accuracy of the downward movement direction of the detection probe 613. As the sliding column 69 continues to move downward, the detection probe 613 will eventually make stable contact with the pin on the electronic component body 2.

[0031] The detection probe 613 transmits the detection signal to the detection station 615 via the connected wire 614. The detection station 615 processes and analyzes the received signal to complete the detection of the electronic component body 2. After the detection is completed, the detection data is clearly displayed on the detection station 615, and this data is simultaneously fed back to the sensor 5. After judging the detection data, the sensor 5 transmits a control signal to the corresponding electric push rod 92 in the push assembly 9. If the detection data meets the preset standard, the sensor 5 sends a signal to the electric push rod 92 on the qualified conveyor 7 side, which then pushes the push plate 93 to push the qualified electronic component body 2 from the detection conveyor 1 to the qualified conveyor 7. If the detection data does not meet the preset standard, the sensor 5 sends a signal to the electric push rod 92 on the unqualified conveyor 8 side, which drives the push plate 93 to push the unqualified electronic component body 2 to the unqualified conveyor 8, thus completing the detection and sorting process of the electronic components.

[0032] Example 2: This example aims to address the problem of detection displacement and its impact on detection accuracy during electronic component testing. This example is an improvement upon Example 1. For details, please refer to [link to example]. Figure 1 - Figure 3 A fixing component 3 is installed on the detection conveyor table 1. The fixing component 3 includes a suction cup 31 fixed on the detection conveyor table 1. The top surface of the suction cup 31 has multiple holes 32. The bottom surface of the suction cup 31 is connected to a connecting pipe 33. The bottom of the connecting pipe 33 is connected to a vacuum pipe 34. The end of the vacuum pipe 34 is connected to a vacuum pump 35. The vacuum pump 35 is fixedly connected to the detection conveyor table 1.

[0033] In this embodiment: when the electronic component body 2 is transported to the preset detection position below the detection probe 613 via the detection conveyor 1, the vacuum pump 35, which is fixedly connected to the detection conveyor 1, is first started. After the vacuum pump 35 starts running, it performs vacuum treatment on the suction cup 31 through the passage formed by the vacuum tube 34 and the connecting tube 33, so that a stable negative pressure environment is formed on the top surface of the suction cup 31. Since the electronic component body 2 is placed on the top surface of the suction cup 31, the negative pressure will generate an adsorption force to firmly fix it on the suction cup 31; at the same time, the multiple drainage holes 32 opened on the top surface of the suction cup 31 can make the negative pressure evenly distributed on the surface of the suction cup 31, ensuring that the force on each part of the electronic component body 2 is balanced, and effectively avoiding damage to the electronic component body 2 due to excessive local force.

[0034] This negative pressure adsorption fixation method can improve the stability of the electronic component body 2 during the testing process, effectively solve the problem of slight displacement that is prone to occur in the testing stage, and further improve the accuracy of the overall testing work.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
