Description

Technical Field

[0001] The present invention relates to the technical field of electronic component measurement, and in particular to an electronic component measuring device. Background Art

[0002] Electronic components are the basic elements in electronic circuits. They generally include a packaged functional body and pins. The pins are connected to the circuit board. During the production of circuit boards or electronic products, vibration tests are required to check the safety and stability of the circuit boards.

[0003] Electronic components also need to be fully inspected or spot-checked before leaving the factory or when being installed to avoid quality problems that affect the overall quality of circuit boards and electronic equipment. Generally, when testing electronic components, the main focus is on measuring their external dimensions and pin lengths, as well as checking their power-on functions. The electronic components are then placed in a testing base for power-on testing, and can be packaged if they pass the test. However, existing testing or measurement devices lack vibration testing for individual electronic components, making it impossible to guarantee the drop resistance of individual electronic components, which may affect the stability of the circuit board. If problems arise during the vibration test of the circuit board, there are relatively many items to be checked, which need to be eliminated one by one, which is time-consuming. Therefore, vibration testing should be added when measuring individual components to improve the yield rate of the finished board and reduce the difficulty of later troubleshooting.

[0004] In the prior art, there is a lack of vibration testing for single electronic components that needs to be solved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an electronic component measuring device in response to the above-mentioned technical deficiencies, which solves the problem of lack of vibration testing of single electronic components in the prior art.

[0006] The technical solution adopted by the present invention is to provide an electronic component measuring device for measuring electronic parts, including a workbench and:

[0007] A rotating table is rotatably arranged on the workbench, and a side surface of the rotating table has a plurality of transversely arranged guide holes at equal angles;

[0008] There are a plurality of guide blocks, each of which is slidably disposed in the guide hole;

[0009] An extension seat is hingedly provided at the end of the guide block. The extension seat slides in the guide hole following the guide block. After sliding to the outside of the guide hole, the extension seat swings horizontally around the guide block. The extension seat has a positioning groove for clamping the electronic component. The pins of the electronic component are located outside the extension seat.

[0010] A vibration box is located above the workbench and is arranged on the workbench to swing back and forth in the horizontal direction. After one of the extension seats slides to the outside of the guide hole, it enters the vibration box, and there is a gap between the side wall of the extension seat and the inner wall of the vibration box.

[0011] Further optimization of this technical solution also includes:

[0012] A brush is arranged on the upper side wall of the vibration box and is used for cleaning electronic parts.

[0013] Further optimization of this technical solution also includes:

[0014] The test seat is arranged on the workbench, and the end side of the test seat has an electrical slot. After one of the extension seats slides toward the outside of the guide hole, the pins of the electronic component are electrically connected to the electrical slot for power-on testing.

[0015] Further optimization of this technical solution also includes:

[0016] a first inspection camera module, disposed on the workbench and located beside the electronic component, wherein the inspection end of the first inspection camera module is horizontally opposite to the pins of the electronic component and is used to detect vertical distortion of the pins and the spacing between the pin ends;

[0017] After the rotating table rotates, an electronic component passes through the vibration box, the first detection camera module and the test seat in sequence.

[0018] Further optimization of this technical solution also includes:

[0019] The second detection camera module is arranged on the workbench, above the first detection camera module and above the electronic component. The detection end of the second detection camera module is opposite to the electronic component and is used to detect the length and horizontal bending of the pin.

[0020] Further optimization of this technical solution also includes:

[0021] A top cover is provided on the workbench and is located above the test socket. When a pin of one of the electronic components is inserted into the electrical slot, the top cover covers the electronic component.

[0022] The temperature measuring component is arranged on the top cover and is used to detect the temperature rise of the electronic component after power is supplied.

[0023] Further optimizing this technical solution, the epitaxial seat includes:

[0024] A mounting seat, hinged to the end of the guide block;

[0025] The positioning module is detachably arranged on the mounting seat, and the positioning groove adapted to the electronic component is located on the positioning module.

[0026] Further optimization of this technical solution also includes:

[0027] There are several linear drive components, which are arranged in the rotating table and are used to drive the guide blocks to slide.

[0028] The beneficial effects of the present invention are:

[0029] 1. During the rotation of several rotating tables, electronic components can be loaded and unloaded with the help of robotic arms or suction cups, and measurement and testing can be performed, with a high degree of automation.

[0030] 2. The vibration box can knock on the extension seat to make the electronic components vibrate and then perform power-on detection to achieve vibration testing.

[0031] 3. The epitaxial seat can swing outside the guide hole, and the vibration box swings and hits the epitaxial seat inside. The epitaxial seat can reduce the impact of vibration on the turntable by swinging, thereby reducing the impact on electronic components in other positions, so that vibration testing and electronic testing can be carried out synchronously and stably, improving efficiency and saving space.

[0043] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] To simplify the drawings, only portions relevant to the invention are schematically depicted in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one component with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0045] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0046] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0047] like Figure 1-10As shown, an electronic component measuring device is used to measure an electronic component 10, including a workbench 1, and also including: a rotating table 2, which is rotatably arranged on the workbench 1, and the side surface of the rotating table 2 has a plurality of transversely arranged guide holes 201 at equal angles; a guide block 3, which has a plurality of guide blocks 3, and the guide block 3 is slidably arranged in the guide hole 201; an extension seat 4, which is hingedly arranged at the end of the guide block 3, and the extension seat 4 follows the guide block 3 to slide in the guide hole 201, and after the extension seat 4 slides to the outside of the guide hole 201, it swings horizontally around the guide block 3, and the extension seat 4 has a positioning groove 4021, and the positioning groove 4021 is used to clamp the electronic component 10, and the pins of the electronic component 10 are located on the outside of the extension seat 4; a vibration box 5, which is located above the workbench 1 and is reciprocatingly swinging on the workbench 1 in the transverse direction, and after one of the extension seats 4 slides to the outside of the guide hole 201, it enters the vibration box 5, and there is a gap between the side wall of the extension seat 4 and the inner wall of the vibration box 5. It also includes: a plurality of linear drive components, which are arranged in the rotating table 2 and are used to drive the guide block 3 to slide.

[0048] When in use, the rotating platform 2 rotates around its own axis, driving the electronic component 10 to rotate to different working positions. The movable suction cup and image recognition technology can be used to transfer a single electronic component 10 to the extension seat 4 (which is the existing technology), and the pins are snapped into the positioning groove 4021 facing outward. At this time, the extension seat 4 is located in the guide hole 201, and the guide hole 201 can limit the extension seat 4, so that the initial position of the extension seat 4 is more stable, which is convenient for stable loading. After loading is completed, the extension seat 4 slides outward, and the guide block 3 is located in the guide hole 201. The extension seat 4 can swing outside the guide hole 201. At the same time, the extension seat 4 enters the vibration box 5. There is a gap between the inner wall of the vibration box 5, especially in the horizontal direction, and the extension seat 4. The vibration box 5 swings back and forth in the horizontal direction, and the extension seat 4 can be knocked to perform a vibration test on the electronic component 10. The swing of the extension seat 4 reduces the transmission of vibration to the rotating table 2, and when the inner wall of the vibration box 5 collides with the extension seat 4, there is activity, the impact damage is low, and the damage to the power source and transmission structure of the vibration box 5 is low. When extension mount 4 is impacted, electronic component 10 is vibrated and rapidly displaced, subject to acceleration changes and inertia. This significantly impacts the vibration compared to when electronic component 10 is stationary, enabling a more comprehensive vibration test. After the vibration, extension mount 4 retracts into guide hole 201, and turntable 2 rotates, moving electronic component 10 to another workstation.

[0049] The power source for the vibration box 5 to swing can be a reciprocating motor or other existing technologies, which is not shown in this application.

[0050] The linear drive assembly can be a linear telescopic motor assembly or a cylinder assembly, etc. The moving end is connected to the guide block 3. By driving the guide block 3 to move, the extension seat 4 can be driven to move.

[0051] The vibration box 5 can be driven directly by a motor or swing through a transmission structure. This is a prior art and can be set on the workbench 1. It is not shown in this application.

[0052] Furthermore, it also includes: a brush 6 arranged on the upper side wall of the vibration box 5 for cleaning the electronic components 10.

[0053] During use, when the electronic component 10 is performing routine power supply testing, generally checking parameters such as resistance and temperature, or whether it is operating normally, the brush 6 can clean the electronic component 10, especially the surface of the pins, to reduce the impact of dust and other substances on the electrical connection and the impact of surface debris and dust on image detection. The brush 6 can perform the cleaning function when the vibration box 5 reciprocates. The brush 6 can be installed on the upper and lower walls inside the vibration box 5.

[0054] Furthermore, it also includes: a test socket 7, which is arranged on the workbench 1, and the end side of the test socket 7 has an electrical slot 701. After one of the extension sockets 4 slides toward the outside of the guide hole 201, the pins of the electronic component 10 are electrically connected to the electrical slot 701 for power-on testing.

[0055] During use, the test socket 7 is a conventional electronic test base. The electronic component 10 is connected to the test socket 7, and automatic testing can be achieved through the test circuit board and other components within the test socket 7, which is conventional technology. The rotating table 2 rotates to transfer the vibrated electronic component 10 to the test station where the test socket 7 is located. The guide block 3 moves and pushes the extension socket 4 outward, allowing the pins to plug and connect with the electrical socket 701, allowing testing to begin. To ensure alignment stability, a portion of the extension socket 4 remains within the guide hole 201, preventing rotation and ensuring accurate alignment. A guide plug or other device can also be provided to ensure that the extension socket 4 and test socket 7 are pre-aligned when they are relatively close, before the pins are inserted into the electrical socket 701. After the power-on test is completed, the post-vibration damage can be confirmed (it is not necessary to confirm whether the component was intact before vibration; a damaged component is considered a defective component, while an intact component is considered a good component that has passed the vibration test). The extension socket 4 retracts, and the material is unloaded using a movable suction cup or other device. Unloading can be performed at a separate station or at the test station.

[0056] Furthermore, it also includes: a first detection camera module 801, which is arranged on the workbench 1 and is located next to the electronic component 10. The detection end of the first detection camera module 801 is horizontally opposite to the pin of the electronic component 10, and is used to detect the vertical distortion of the pin and the spacing between the pin ends; wherein, after the rotating table 2 rotates, an electronic component 10 passes through the vibration box 5, the first detection camera module 801 and the test seat 7 in sequence.

[0057] When in use, the first detection camera module 801 can measure the spacing between multiple pins from the horizontal side through image recognition technology, and can also identify whether the pins are bent up and down and twisted up and down. Pins that are excessively bent up and down or twisted up and down are defective products and are not easy to install smoothly on the circuit board and need to be adjusted before use.

[0058] After inspection by the first inspection camera module 801, the defective electronic component 10 is marked, and if the pin deformation is too large, it is directly determined that the electronic component 10 does not need to be powered on for testing and does not need to be connected to the test socket 7, otherwise it may cause damage due to insertion impact.

[0059] Of course, after the image recognition detection, a clamping device can be added to calibrate the pins, and then the pins can be transferred to the test socket 7 for power-on testing.

[0060] Furthermore, it also includes: a second detection camera module 802, which is arranged on the workbench 1, above the first detection camera module 801, and above the electronic component 10, and the detection end of the second detection camera module 802 is opposite to the electronic component 10 above and below, and is used to detect the pin length and horizontal bending.

[0061] When in use, the second detection camera module 802 is located at the top, and can detect the length of the pin and the horizontal square bending. Pins with excessive horizontal bending are also defective.

[0062] By cooperating with the first detection camera module 801 and the second detection camera module 802 , the pins can be comprehensively image-recognized and detected, and parameters such as the spacing and length of the pins can be measured.

[0063] Furthermore, it also includes: a top cover 9, which is arranged on the workbench 1 and located above the test socket 7. When the pins of one of the electronic components 10 are inserted into the electrical slot 701, the top cover 9 covers the top of the electronic component 10; a temperature measuring component 901, which is arranged on the top cover 9 and is used to detect the temperature rise of the electronic component 10 after power is supplied.

[0064] During use, while the electronic component 10 is being powered on and tested on the test socket 7, a temperature measurement can be performed simultaneously to determine whether the temperature rise is normal. With the extension socket 4 positioned close to the test socket 7 and the pins inserted into the electrical slot 701, the electronic component 10 within the positioning slot 4021 is positioned below the top cover 9. The top cover 9 and the upper end of the extension socket 4 are in contact or spaced relatively close together, minimizing the impact of the external environment on the interior of the positioning slot 4021 and improving the accuracy of the temperature measurement assembly 901 in detecting the temperature of the electronic component 10.

[0065] Furthermore, the extension seat 4 includes: a mounting seat 401 hinged to the end of the guide block 3; a positioning module 402 detachably provided on the mounting seat 401, and the positioning groove 4021 adapted to the electronic component 10 is located on the positioning module 402.

[0066] When in use, the extension seat 4 includes a mounting seat 401 and a positioning module 402. The positioning module 402 can be detachably installed on the mounting seat 401 through a plug-in or threaded connection structure. Different positioning modules 402 can be installed according to different electronic components 10, which is convenient for detecting and using a variety of electronic components 10.

[0067] In this application, the rotating table 2 can be a quadrilateral, with guide holes 201 set on all four sides. Guide blocks 3 and sliders are set in the four guide holes 201. The vibration box 5, the first detection camera module 801 and the test seat 7 are respectively located in three directions, and the other direction can be the unloading area.

[0068] It will be understood that the present invention is described by way of some embodiments, and it will be appreciated by those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
