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

[0002] In the manufacturing process of electronic components, comprehensive and accurate testing of each circuit board is crucial to ensure product quality and performance. Flying probe testing, as an efficient and reliable testing method, is widely used in this field. It uses a flexibly moving probe to precisely contact various test points on the circuit board, quickly identifying defects such as open circuits, short circuits, and poor component soldering. This plays an irreplaceable role in timely detection of quality problems in the production process, preventing defective products from entering the market, and ensuring the stable operation of electronic equipment.

[0003] However, in traditional operating models, manual intervention is often required to transfer electronic components between the testing area and the loading / unloading area. Workers must manually place the electronic components to be tested onto the testing table, remove them after testing, and replace them with new components. This manual operation not only consumes a significant amount of time and manpower, resulting in low overall testing efficiency, but is also prone to errors due to human factors, affecting the accuracy and consistency of the testing.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0017] Example: This example provides an automatic screening device, see [link to example]. Figure 1-4 Specifically, the system includes a flying probe tester body 1, a main shaft 11 rotatably mounted in the middle of the frame of the flying probe tester body 1, a disc-shaped testing table 12 fixedly mounted on the upper end of the main shaft 11, two placement frames 13 symmetrically arranged on the testing table 12 for placing electronic components, a servo motor 14 fixedly mounted inside the frame of the flying probe tester body 1, the output end of the servo motor 14 being connected to the lower end of the main shaft 11 for transmission, a conveying assembly 4 for conveying electronic components and a picking assembly 5 for performing loading and unloading operations on the frame of the flying probe tester body 1, the conveying assembly 4, the picking assembly 5 and the two placement frames 13 on the testing table 12 together constitute an automatic template sorting structure.

[0018] In this embodiment, the flying probe tester body 1 is a prior art technology, mainly used to test the insulation and continuity values ​​of circuit boards. It can monitor the testing process and fault points in real time to ensure the accuracy of the test. The servo motor 14 drives the spindle 11 to rotate, which in turn drives the test table 12 to rotate, so that the two placement frames 13 alternately occupy the test position and the loading / unloading position. The pick-up component 5 picks up and places electronic components from the conveying component 4 into the placement frame 13 or reverses the operation to realize automatic screening and testing. In this screening structure, the servo motor 14, the conveying component 4, and the pick-up component 5 are linearly connected to the PLC. After the conveying component 4 is transported to the designated position by the control of the PLC, the pick-up component 5 is controlled to transport the electronic components on the conveying component 4 into the placement frame 13. Finally, the servo motor 14 is controlled to rotate, so that the electronic components in the placement frame 13 rotate to below the test point. The pick-up component 5 transports the tested electronic components in the other placement frame 13 back to the conveying component 4 to realize automatic screening operation. It can carry out uninterrupted assembly line operation, which significantly improves the overall efficiency and production capacity of flying probe testing.

[0019] In the specific implementation process, such as Figure 1 and Figure 2 As shown, a semi-circular guide groove 2 is provided on the upper surface of the frame of the flying probe tester body 1, and a guide rod 21 is fixedly provided on the lower edge of the test table 12, with the lower end of the guide rod 21 located in the guide groove 2.

[0020] In this embodiment, when the testing platform 12 rotates, the guide rod 21 moves along the semi-circular guide groove 2, limiting the rotation range and direction of the testing platform 12, ensuring that the testing platform 12 rotates smoothly, and preventing it from deviating or shaking.

[0021] In the specific implementation process, such as Figure 1 and Figure 2 As shown, a positioning cylinder 3 is fixedly installed on the upper surface of the frame of the flying probe tester 1. Two positioning slots 31 are symmetrically arranged on the test table 12. The output end of the positioning cylinder 3 is used to extend into the positioning slot 31 to realize the positioning of the test table 12.

[0022] In this embodiment, when the detection table 12 rotates to a suitable position (such as the detection position or the loading / unloading position), the output end of the positioning cylinder 3 extends into the corresponding positioning groove 31 to prevent the detection table 12 from continuing to rotate, thereby achieving precise positioning of the detection table 12 and ensuring the accuracy of detection and loading / unloading operations.

[0023] In the specific implementation process, such as Figure 1 and Figure 3As shown, the conveying assembly 4 includes a mounting frame 41 fixedly installed on the frame of the flying probe tester body 1, and a belt conveyor 42 is mounted on the mounting frame 41. The belt conveyor 42 is driven by a motor to rotate the belt in a circular motion. Electronic components are placed on the belt and are conveyed to the designated position as the belt moves, making it convenient to pick up the assembly 5 for material handling.

[0024] In the specific implementation process, such as Figure 1 and Figure 4 As shown, the picking component 5 includes a gantry 51 fixedly installed on the upper surface of the frame of the flying probe tester body 1. A linear guide rail 52 is fixedly provided in the middle of the gantry 51. A fixed plate 53 is fixedly provided at the lower end of the slider of the linear guide rail 52. Two piston cylinders 54 are fixedly provided on the fixed plate 53. A lifting plate 55 is slidably provided on the fixed plate 53. The output end of the piston cylinder 54 is fixedly connected to the upper surface of the lifting plate 55. Two picking components are vertically installed on the lifting plate 55.

[0025] In this embodiment, the linear guide rail 52 drives the slider to move via a motor-driven lead screw, thereby causing the fixed plate 53 to move linearly in the horizontal direction. This enables the retrieval component 5 to move between different positions to reach the placement or removal location of the electronic component. The piston cylinder 54 actuates, extending or retracting its output end, causing the lifting plate 55 to slide up and down on the fixed plate 53. This allows the retrieval component mounted on the lifting plate 55 to reach a suitable height for retrieval or placement operations.

[0026] In the specific implementation process, such as Figure 1 and Figure 4 As shown, the material handling component includes a suction cup body 6 and a vacuum generator 61 fixedly mounted on the lifting plate 55. The pipe of the suction cup body 6 is fixedly connected to the connector of the vacuum generator 61. The suction cup body 6 is used to adsorb electronic components; the vacuum generator 61 is used to generate negative pressure so that the suction cup body 6 can adhere to the electronic components.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
