Description

Technical Field

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

[0002] Electronic components are the basic elements in electronic circuits, generally including a packaged functional body and pins. The pins are connected to the circuit board behind the circuit. When the circuit board or electronic product is produced, vibration tests need to be carried out to check the safety and stability of the circuit board.

[0003] When the electronic components leave the factory or are installed, they also need to be comprehensively inspected or sampled to avoid quality problems that affect the overall quality of the circuit board and electronic equipment. Generally, when doing electronic component detection, the main measurements are on their appearance dimensions, pin lengths, and the power-on function is checked. The electronic components are installed in the detection base for power-on testing, and if the detection is qualified, they can be encapsulated. However, in the existing detection or measurement devices, there is a lack of vibration detection for single electronic components, and the anti-drop stability of single electronic components cannot be guaranteed, which may affect the stability of the circuit board. If there are problems during the vibration test of the circuit board, there are relatively many items to be excluded one by one, which takes a long time. Vibration tests should be added during the measurement of single components to improve the yield rate of the finished board and reduce the difficulty of later troubleshooting.

[0004] In the prior art, the problem of lacking vibration testing for single electronic components needs to be solved. Summary of the Invention

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

[0006] The technical solution adopted by the present invention is: to provide an electronic component measurement device for measuring electronic components, including a workbench, and further including: A rotating table rotatably arranged on the workbench, and a plurality of horizontally arranged guiding holes are equiangularly spaced on the side surface of the rotating table; There are a plurality of guiding blocks slidably arranged in the guiding holes; An extension seat is hinged to the end of the guiding block. The extension seat follows the guiding block and slides in the guiding hole. After the extension seat slides out of the guiding hole, it swings horizontally around the guiding block. A positioning groove is provided on the extension seat, and the positioning groove is used for clamping the electronic component, and the pins of the electronic component are located outside the extension seat; The vibration box is located above the workbench and is reciprocally swingably arranged on the workbench in the transverse direction. After one of the extension seats slides outside 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.

[0007] To further optimize this technical solution, it further includes: A brush is arranged on the upper side wall inside the vibration box and is used for cleaning the electronic components.

[0008] To further optimize this technical solution, it further includes: A test socket is arranged on the workbench. The end side of the test socket has an electrical slot. After one of the extension seats slides outside the guide hole, the pins of the electronic component are electrically connected to the electrical slot for power-on testing.

[0009] To further optimize this technical solution, it further includes: A first detection camera module is arranged on the workbench, beside the electronic component. The detection end of the first detection camera module is horizontally opposite to the pins of the electronic component and is used for detecting the vertical distortion of the pins and the interval at the ends of the pins. Among them, after the rotating table rotates, an electronic component sequentially passes through the vibration box, the first detection camera module, and the test socket.

[0010] To further optimize this technical solution, it further includes: A 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 vertically opposite to the electronic component and is used for detecting the length of the pins and the horizontal bending.

[0011] To further optimize this technical solution, it further includes: A top cover is arranged on the workbench and above the test socket. When the pins of one of the electronic components are inserted into the electrical slot, the top cover covers above the electronic component. A temperature measurement component is arranged on the top cover and is used for detecting the temperature rise of the electronic component after power-on.

[0012] To further optimize this technical solution, the extension seat includes: A mounting seat is hinged to the end of the guide block; A positioning module is detachably arranged on the mounting seat, and the positioning slot adapted to the electronic component is located on the positioning module.

[0013] To further optimize this technical solution, it further includes: There are several linear drive components arranged inside the rotating table and are used for driving the guide block to slide.

[0014] The beneficial effects of the present invention are as follows: 1. During the rotation of several rotating platforms, the loading and unloading of electronic components can be achieved by means of a robotic arm or a suction cup, etc., and measurement and detection can be carried out, with a high degree of automation.

[0015] 2. The vibration box can knock the epitaxial seat, so that the electronic components vibrate and then power-on detection, etc. can be carried out to realize vibration testing.

[0016] 3. The epitaxial seat can swing outside the guiding hole, and the vibration box swings to knock the internal epitaxial seat. Through swinging, the epitaxial seat can reduce the influence of vibration on the rotating platform, thereby reducing the influence on the electronic components in other positions, enabling the vibration testing and electronic detection to be carried out synchronously and stably, improving efficiency and saving space occupancy.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0019] For the sake of simplicity of the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, for the sake of simplicity and easy understanding of the drawings, in some figures, only one of the components with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only this one", but also can mean "more than one" situation, and "several" includes "two" and "more than two".

[0020] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "install", "connect", and "couple" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0021] In addition, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0022] As Figure 1-10 shown, an electronic component measuring device for measuring an electronic component 10 includes a workbench 1, and further includes: a rotating table 2 rotatably arranged on the workbench 1, and a plurality of horizontally arranged guiding holes 201 are equiangularly spaced on the side surface of the rotating table 2; a plurality of guiding blocks 3 are slidably arranged in the guiding holes 201; an extension base 4 is hinged to the end of the guiding block 3, and the extension base 4 follows the guiding block 3 and slides in the guiding hole 201. After the extension base 4 slides out of the guiding hole 201, it swings horizontally around the guiding block 3. A positioning groove 4021 is formed on the extension base 4 for clamping the electronic component 10, and the pins of the electronic component 10 are located outside the extension base 4; a vibration box 5 is located above the workbench 1 and reciprocally swings horizontally on the workbench 1. After one of the extension bases 4 slides out of the guiding hole 201, it enters the vibration box 5, and there is a gap between the side wall of the extension base 4 and the inner wall of the vibration box 5. It further includes: a plurality of linear driving components arranged in the rotating table 2 for driving the guiding blocks 3 to slide.

[0023] During use, the rotating table 2 rotates around its own axis, driving the electronic component 10 to rotate to different workstations. The single electronic component 10 can be transferred to the epitaxial seat 4 (which is prior art) by using a moving suction cup and image recognition technology, and the pins are externally clamped in the positioning groove 4021. At this time, the epitaxial seat 4 is located in the guiding hole 201, and the guiding hole 201 can limit the epitaxial seat 4, making the initial position of the epitaxial seat 4 more stable, facilitating stable feeding. After the feeding is completed, the epitaxial seat 4 slides outwards. The guiding block 3 is located in the guiding hole 201, and the epitaxial seat 4 can swing outside the guiding hole 201. At the same time, the epitaxial 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 epitaxial seat 4. When the vibration box 5 swings reciprocally in the horizontal direction, it can strike the epitaxial seat 4 to perform a vibration test on the electronic component 10. Through the swing of the epitaxial seat 4, the transmission of vibration to the rotating table 2 is reduced. And when the inner wall of the vibration box 5 impacts the epitaxial seat 4, there is a certain amount of movement, and the impact damage is relatively low, resulting in relatively low damage to the power source and transmission structure of the vibration box 5. When the epitaxial seat 4 is impacted, the electronic component 10 is affected by vibration and at the same time generates a rapid displacement, with acceleration changes and inertial effects, which has a greater impact on the vibration of the electronic component 10 compared to the state where the position of the electronic component 10 is fixed, achieving a more sufficient vibration test. After the vibration, the epitaxial seat 4 retracts into the guiding hole 201, and the rotating table 2 rotates to drive the electronic component 10 to move to other workstations.

[0024] The power source for the swing of the vibration box 5 can be a reciprocating rotating motor or other prior art, which is not shown in this application.

[0025] The linear drive assembly can be a linear telescopic motor assembly or a cylinder assembly, etc. The mobile end is connected to the guiding block 3, and driving the guiding block 3 to move can drive the epitaxial seat 4 to move.

[0026] The vibration box 5 can achieve swinging through direct drive by a motor or through a transmission structure, which is prior art and can be arranged on the workbench 1, and is not shown in this application.

[0027] Further, it further includes: a brush 6, which is arranged on the upper side wall inside the vibration box 5 and is used to clean the electronic component 10.

[0028] During use, when the electronic component 10 is undergoing routine power supply detection, generally parameters such as resistance and temperature are detected or whether it works normally. The brush 6 can clean the electronic component 10, especially the surface of the pins, reducing the influence of dust, etc. on electrical connection, and also reducing the influence of surface debris and dust on image detection. When the vibration box 5 swings reciprocally, the brush 6 can achieve the cleaning function, and the brush 6 can be arranged on both the upper and lower inner walls of the vibration box 5.

[0029] Further, it further includes: a test socket 7, which is arranged on the workbench 1, and the end side of the test socket 7 has an electrical socket 701. After one of the epitaxial sockets 4 slides out of the guiding hole 201, the pins of the electronic component 10 are electrically connected to the electrical socket 701 for power-on testing.

[0030] 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 of the test socket 7, which is prior art. The rotating table 2 rotates to transfer the vibrated electronic component 10 to the test station where the test socket 7 is located. The guiding block 3 moves to push the epitaxial socket 4 outwards, so that the pins are inserted and connected to the electrical socket 701, and then testing can be carried out. To ensure the alignment stability, a part of the epitaxial socket 4 is still inside the guiding hole 201 and will not rotate, and the alignment is accurate. At the same time, guiding plugs and the like can be set so that when the epitaxial socket 4 and the test socket 7 are relatively close, they are inserted and aligned in advance, and then the pins are inserted into the electrical socket 701. After the power-on detection is completed, it can be confirmed whether it is damaged after vibration (it is not necessary to confirm whether it is intact before vibration. If it is damaged, it is a defective part, and if it is intact, it is a good product that passes the vibration test). The epitaxial socket 4 retracts, and blanking can be carried out through a moving suction cup or the like. Blanking can be carried out at a separate station or at the test station.

[0031] Further, it further includes: a first detection camera module 801, which is arranged on the workbench 1 and beside the electronic component 10. The detection end of the first detection camera module 801 is horizontally opposite to the pins of the electronic component 10 for detecting the vertical distortion of the pins and the interval between the ends of the pins; wherein, after the rotating table 2 rotates, an electronic component 10 sequentially passes through the vibration box 5, the first detection camera module 801 and the test socket 7.

[0032] During use, the first detection camera module 801 can measure the intervals of multiple pins from the side in the horizontal direction through image recognition technology, and at the same time can identify whether the pins are bent up and down and twisted in the up and down direction. Pins that are bent up and down too much and twisted in the up and down direction too much are defective products and are not convenient to be smoothly installed on the circuit board and need to be adjusted before use.

[0033] After being detected by the first detection camera module 801, if the electronic component 10 with defective marks and the pin deformation is too large, it is directly determined that the electronic component 10 does not perform power-on testing and does not need to be connected to the test socket 7, otherwise it may cause plugging and impact damage.

[0034] Of course, after image recognition detection, clamping equipment can be added to correct the pins, and then it is transferred to the test socket 7 for power-on testing.

[0035] Further, it further 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. The detection end of the second detection camera module 802 faces the electronic component 10 up and down, and is used to detect the pin length and horizontal bending.

[0036] During use, the second detection camera module 802 is located above, and can detect the pin length and the bending of the horizontal square. Pins with excessive horizontal bending are also defective products.

[0037] Through the cooperation of the first detection camera module 801 and the second detection camera module 802, image recognition detection of the pins can be carried out more comprehensively, and parameters such as the interval and length of the pins can be measured.

[0038] Further, it further includes: a top cover 9, which is arranged on the workbench 1 and above the test socket 7. After the pins of one of the electronic components 10 are inserted into the electrical slot 701, the top cover 9 covers above the electronic component 10; a temperature measurement component 901, which is arranged on the top cover 9 and is used to detect the temperature rise after the electronic component 10 is powered on.

[0039] During use, when the electronic component 10 is powered on and tested on the test socket 7, temperature detection can be carried out simultaneously to judge whether the temperature rise during the power-on operation is normal. The extension socket 4 is close to the test socket 7. After the pins are inserted into the electrical slot 701, the electronic component 10 in the positioning groove 4021 is located below the top cover 9. There is an abutment or a small gap between the top cover 9 and the upper end of the extension socket 4, which can reduce the influence of the external environment on the positioning groove 4021 and improve the temperature detection accuracy of the temperature measurement component 901 for the electronic component 10.

[0040] Further, the extension socket 4 includes: a mounting seat 401, which is hinged to the end of the guide block 3; a positioning module 402, which is detachably arranged on the mounting seat 401, and the positioning groove 4021 adapted to the electronic component 10 is located on the positioning module 402.

[0041] During use, the extension socket 4 includes a mounting seat 401 and a positioning module 402. The positioning module 402 can be detachably mounted on the mounting seat 401 through structures such as plugging or threaded connection. Then, different positioning modules 402 can be adaptively installed according to different electronic components 10, which is convenient for detecting and using various electronic components 10.

[0042] In this application, the rotating table 2 can be quadrilateral, and guide holes 201 are arranged on all four sides. Guide blocks 3 and sliders are arranged in all four guide holes 201. The vibration box 5, the first detection camera module 801 and the test socket 7 are respectively located in three directions, and the other direction can be a blanking area.

[0043] It will be understood that the present invention is described by way of some embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present invention. Additionally, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
