[0002] Electronic components are the basic elements in electronic circuits. They are usually individually packaged and have two or more leads or metal contacts. Electronic components must be connected to each other to form an electronic circuit with specific functions.

[0003] Existing electronic component inspection tools generally inspect components soldered on circuit boards to check whether the solder joints of the components are normal. Generally, the circuit board with the components installed is placed on a testing platform, and then the inspection probe is electrically connected to the component for inspection. However, when inspecting existing components, the previous component needs to be removed after inspection, and then the next component can be placed on the testing platform for inspection. It is not possible to load and unload the components during inspection, resulting in poor performance. In addition, existing components need to be fixed by a clamping mechanism during inspection to prevent the position of the components from shifting during inspection. However, when loading and unloading, the staff needs to disassemble the clamping mechanism before loading and unloading the components, which is inconvenient. To this end, we propose an electronic component inspection tool. Utility Model Content

[0029] It should be noted that if Figure 3 As shown, sliders 26 are installed on both sides of the second movable plate 16, and guide rails 17 are installed on both sides of the interior of the U-shaped frame 15. Each slider 26 is slidably connected to the corresponding guide rail 17. In actual use, the second movable plate 16 can be limited by the cooperation between the guide rail 17 and the slider 26, so that the second movable plate 16 remains stable.

[0030] like Figure 1 and Figure 2 As shown, two first movable plates 6 are provided on the top of the workbench 2, and the first movable plates 6 are connected by a connecting plate 4. A support plate 9 is installed on the top of each first movable plate 6. During actual use, the staff can place the circuit board with components installed on the support plate 9, and then detect it through the probe 20.

[0031] It should be noted that if Figure 1 and Figure 3 As shown, positioning plates 18 are installed on both sides of the interior of the U-shaped frame 15. The top of the positioning plate 18 is flush with the bottom of the guide rail 17, and when the bottom of the slider 26 is flush with the top of the positioning plate 18, the bottom of the probe 20 contacts the preset position of the component placed on the top of the pallet 9. During actual use, the probe 20 can be positioned by the positioning plate 18, so that the probe 20 can be electrically connected to the component on the pallet 9 when it moves to the lowest end, and the component can be tested.

[0032] It should be noted that a mounting plate 12 is installed on one side of the U-shaped frame 15, and a display screen 11 is installed on one side of the mounting plate 12. The display screen 11 is connected to the controller through a wire. During actual use, the probe 20 will transmit the data of component detection to the controller, and the controller will then transmit the data to the display screen 11 for display for the staff to observe, so that the staff can understand whether the component has failed.

[0033] like Figure 1 and Figure 2As shown, both sides of the bottom of the U-shaped frame 15 are provided with through grooves 19, the first movable plate 6 and the connecting plate 4 are penetrated by the through grooves 19, the top of the workbench 2 is provided with a slide groove 27, the slide groove 27 is located below the U-shaped frame 15, and the bottom of the connecting plate 4 is installed with a sliding plate 22, the bottom of the sliding plate 22 passes through the slide groove 27 and extends to the bottom of the workbench 2, the bottom of the workbench 2 is symmetrically installed with two fixed blocks 3, the two fixed blocks 3 are rotatably connected with a screw rod 21, one end of the screw rod 21 passes through the sliding plate 22 and is threaded with the sliding plate 22, and one end of the screw rod 21 is connected to Drive motor 23, drive motor 23 is fixed on the fixed block 3, drive motor 23 is connected to the controller through a wire. During actual use, the staff can drive the drive motor 23 to work through the controller, and the drive motor 23 can control the movement of the first movable plate 6 under the action of the screw rod 21 and the sliding plate 22. Then, when the components on one of the support plates 9 are inspected, the other first movable plate 6 will move to the outside of the U-shaped frame 15, so that the next component to be inspected can be placed on the support plate 9 while inspecting, and loading and unloading can be completed during the inspection process.

[0034] It should be noted that when one side of the sliding plate 22 contacts one end of the slide groove 27, one of the first movable plates 6 will move to directly below the probe 20. When in use, the first movable plate 6 can be positioned so that the first movable plate 6 is located at a preset position inside the U-shaped frame 15. In this way, during detection, the position of the components on the first movable plate 6 will not be offset.

[0035] like Figure 2 and Figure 4 As shown, the top edge of the first movable plate 6 is provided with a groove 5, and two adjacent grooves 5 are connected end to end, and a border 8 is provided in the groove 5. The inner surface of the border 8 is flush with the edge of the support plate 9, and the top of the border 8 extends above the support plate 9. During actual use, the border 8 can limit the components placed on the support plate 9, so that the components are located at the preset position on the support plate 9 and will not be offset.

[0036] like Figure 2 and Figure 4As shown, strip connecting blocks 7 are installed on both sides of the top of each edge 8, and accommodating grooves 25 are opened on both sides of the top of each first movable plate 6, the accommodating grooves 25 are located below the strip connecting blocks 7, and at least one guide rod 10 is vertically installed inside each accommodating groove 25, the top of the guide rod 10 slides through the strip connecting block 7, and the side of each guide rod 10 is sleeved with a spring 24, the top of the spring 24 is against the bottom of the strip connecting block 7, and the bottom of the spring 24 is against the bottom of the accommodating groove 25. In actual use, the elastic force of the spring 24 can lift the edge 8, so that the edge 8 limits the components placed on the support plate 9, and when the inspection is completed and the material needs to be taken, the staff only needs to press down the edge 8, and the spring 24 is compressed to press the edge 8 to the bottom of the support plate 9, which will not hinder the material taking.

[0037] It should be noted that when the bottom of the edge 8 moves to the bottom of the groove 5, the top of the edge 8 is lower than the top of the pallet 9, so that when the components are removed from the pallet 9, the edge 8 will not cause any obstruction to the pallet 9.

[0038] Specifically, when the present invention is in use, the staff puts the components with inspection and the circuit board connected to the components on the support plate 9, and the edge 8 limits the components and the circuit board, and then controls the driving motor 23 to work through the controller, and the driving motor 23 drives the screw rod 21 to rotate. With the cooperation of the screw rod 21 and the sliding plate 22, the first movable plate 6 where the components are placed moves to the inside of the U-shaped frame 15, and at the same time, the other first movable plate 6 moves out of the U-shaped frame 15. When one side of the sliding plate 22 contacts one side of the slide groove 27, the components move to the preset position inside the U-shaped frame 15, and then the telescopic mechanism 14 is controlled to extend through the controller, and the telescopic mechanism 14 pushes the probe 20 to electrically connect with the component, detect the component, and transmit the detection data to the controller, and then the controller transmits it to the display screen 11 for observation by the staff. At the same time, during the detection process, the staff can When the component being inspected is inspected, the controller's telescopic mechanism 14 contracts, and the probe 20 is separated from the component. Then, the drive motor 23 is controlled to reverse and the inspected component is moved out of the U-shaped frame 15. When the other side of the sliding plate 22 contacts the other end of the slide groove 27, the first movable plate 6 where the uninspected component is placed moves to a preset position in the U-shaped frame 15. Then, the controller controls the telescopic mechanism 14 to extend so that the probe 20 contacts the component for inspection. At the same time, the staff can press the edge 8 downward to press the edge 8 under the support plate 9, and then the staff can remove the component from the support plate 9. After that, when the staff's hand falls off the edge 8, the edge 8 returns to its original position under the elastic force of the spring 24. After that, the staff can place the component and the circuit board connected to the component on the support plate 9 to complete the loading and unloading.

[0039] Furthermore, if Figure 3 As shown, a limiting rod 28 is installed inside the slide groove 27, and one end of the limiting rod 28 slides through the sliding plate 22. Under the action of the limiting rod 28, the sliding plate 22 can be limited so that the sliding plate 22 remains stable, so that the first movable plate 6 will not shake during use.

[0040] Furthermore, if Figure 1 As shown, a plurality of legs 1 are installed on the bottom edge of the workbench 2, and the bottom of the legs 1 extends to the bottom of the drive motor 23.
