Description

Technical Field

[0001] The present invention belongs to the field of electronic component detection, and specifically relates to a device for detecting the yield of finished electronic components. Background Art

[0002] Electronic components refer to the basic components that make up an electronic circuit and can be used alone or in combination to build complex electronic systems and devices. Electronic components include: resistors, which are used to limit the flow of current or divide voltage; capacitors, which are used to store and release electrical energy and are also used for filtering and coupling; etc.

[0003] In order to ensure the quality of finished electronic components, it is necessary to conduct quality inspections on electronic components before leaving the factory. Qualified ones are good products, including: electrical performance inspection: measuring the electrical parameters of components, such as resistance value, capacitance value, etc., to ensure that they conform to the markings and the requirements of the product BOM; appearance inspection: visually inspecting the appearance of components at a distance from the sample under natural light or fluorescent light to check for damage, severe stains, oxidation, fractures, etc.; etc.

[0004] When detecting the yield rate of electronic components, not only power-on measurement is required to detect internal functions, but also for electronic components such as resistors and capacitors, it is necessary to check the integrity of the resistor appearance, including whether the pins are intact and whether there are scratches or dirt on the surface; it is necessary to check whether the capacitor package is intact and whether there is liquid leakage, deformation, or cracks, etc. Conventionally, it generally relies on the naked eye for inspection, which not only consumes a large amount of human resources, but also has general detection efficiency and accuracy.

[0005] Therefore, the present invention provides a device for detecting the yield of finished electronic components. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A device for detecting the yield of finished electronic components according to the present invention includes two conveyor belts, the two conveyor belts are arranged in parallel, a steering wheel is arranged between one ends of the two conveyor belts, the steering wheel is used for transporting the electronic components transported on the two conveyor belts, an electric slide rail is arranged above the conveyor belts, the electric slide rail is arranged in a rectangle, and two of the sides of the rectangle are parallel to the length directions of the two conveyor belts, an optical camera is installed on the moving end of the electric slide rail, and the observation position of the optical camera is located on the upper surfaces of the two conveyor belts; Through the settings of an optical camera and two conveyor belts, the electronic components to be detected are placed on one of the conveyor belts. When the electronic components move to the observation area of the optical camera, the conveyor belt still keeps transporting and running. At the same time, the electric slide rail controls the horizontal movement of the optical camera, and the moving speed is the same as the speed and direction of the conveyor belt. At this time, the optical camera can keep relatively stationary with the electronic components, so as to observe whether there are defects on the surface of the electronic components. As the electronic components continue to move forward, they will fall into the turntable from the end of the conveyor belt. Through the rotation of the turntable, the electronic components are transferred to another conveyor belt. Since the electric slide rail is arranged in a ring shape, and two of the sides of the electric slide rail are parallel to the two conveyor belts, the optical camera can be moved above the other conveyor belt. When the conveyor belt transfers the electronic components that have been detected once to the position where they can be detected by the optical camera, the optical camera moves synchronously and in the same direction with the conveyor belt again, so that the optical camera can observe the electronic components synchronously again. Since the electronic components have changed their postures after experiencing the rotational transfer of the turntable, observing the electronic components again can detect the parts that were not detected during the previous detection process. A sorting device is arranged at the tail of the other conveyor belt. The optical camera transmits the detected signal to the sorting device, and different types of finished products can be sorted. Through this setting, the surface of the electronic components can be effectively observed and detected, and the defects existing on the surface of the electronic components can be fully detected. Only in a very small probability, during the two detections, the defective parts are in the positions that cannot be detected by the optical camera. And during the detection process, the electronic components are always in a moving and transporting state, and there is no need to stop the conveyor belt for detection. This not only improves the detection efficiency, but also when the conveyor belt stops, the electronic components will shake under the action of inertia, which is likely to cause inaccurate detection. This method effectively improves the detection accuracy. At the same time, the whole device is purely mechanically controlled without manual assistance, effectively reducing the labor cost.

[0008] Preferably, the two conveyor belts are arranged in a high-low staggered manner. The turntable is arranged between the two conveyor belts. A driving motor 1 for driving the rotation of the turntable is arranged at the bottom of the turntable. A guiding frame for guiding the movement of the electronic components is arranged above the turntable. The turntable is between the two conveyor belts. After the electronic components that have undergone one detection fall from the end of the conveyor belt onto the turntable, as the turntable rotates, the electronic components will be transferred above the other conveyor belt and finally fall onto the other conveyor belt. The surface of the turntable is covered with a flexible pad, and the dropping impact will not affect the electronic components. The setting of the guiding frame is to ensure that the electronic components can accurately move onto the other conveyor belt. Since the electronic components have experienced two drops and the rotational transportation of the turntable, their self-orientations have been greatly changed, ensuring that the outer surfaces of the electronic components can be fully detected in the two detections, and the electronic components that are not fully detected with a very small probability can be ignored.

[0009] Preferably, the optical camera is inclined. A moving seat is fixedly connected to the moving end of the electric slide rail. An adjusting frame is installed below the moving seat. The two ends of the bottom of the adjusting frame are horizontally arranged, and an adjusting motor is installed at the bottom end of the adjusting frame. The output end of the adjusting motor is fixedly connected to the outside of the optical camera. A plurality of electric telescopic rods two for adjusting the height of the electric slide rail are fixedly connected to the top of the electric slide rail. The inclined optical camera observes the electronic components from an oblique upper direction. Compared with observing from directly above, more sides of the electronic components can be observed. The inclination angle of the optical camera can be controlled by rotating the adjusting motor. At the same time, the electric telescopic rods two can also control the lifting of the electric slide rail. When facing electronic components of different volumes, the optical camera can observe the electronic components at the best angle.

[0010] Preferably, there are two moving ends of the electric slide rail, and both moving ends are connected to the moving seat. A driving motor two for controlling the rotation of the adjusting frame is installed between the moving seat and the adjusting frame. In order to further improve the detection efficiency, two optical cameras can be used to work in coordination. After the electronic components are detected by the first optical camera, the subsequent detection is handed over to the second optical camera, and then the pictures taken twice are integrated. In this way, it is not necessary to wait for one electronic component to be detected and then place a new one for detection. Instead, the electronic components can be placed at a uniform speed for detection. Since the placement speed is the same, it can be calculated when the electronic component reaches the shooting position of the second optical camera, so that the corresponding second photo can be accurately found to ensure the smooth progress of the detection. The driving motor two is used to adjust the orientation of the optical camera to adapt to the installation process of the two optical cameras.

[0011] Preferably, the guiding frame is composed of two arc-shaped plates. The bottom surface of the arc-shaped plate is slidably fitted with the top surface of the steering wheel. A guiding channel is formed between the two arc-shaped plates. The two ends of the channel are respectively adapted to the two ends of the two conveyor belts. A suspension frame is fixedly connected above the arc-shaped plate, and the suspension frame is fixedly connected to the conveyor belt. When the electronic components fall above the steering wheel, they will be restricted in the guiding channel. Then, with the rotation of the steering wheel, the electronic components will enter the second conveyor belt accurately along the guiding channel, thereby ensuring the smooth progress of the detection process. Moreover, the whole structure is simple and convenient, reducing the failure rate, and can smoothly transfer electronic components of different volumes and shapes. By adjusting the rotation speed of the steering wheel, the speed of transferring the electronic components can be adjusted, and the operation is also very convenient.

[0012] Preferably, the conveyor belt includes a support frame. A plurality of driving rollers are arranged in the middle of the support frame. A conveyor belt is sleeved outside the plurality of driving rollers. One end of the support frame away from the steering wheel is installed with a power box capable of driving a plurality of driving rollers to rotate simultaneously. The suspension bracket is fixedly connected to the support frame. A servo motor is arranged in the power box. A transmission shaft is connected between one ends of the plurality of driving rollers. The servo motor drives the transmission shaft to rotate, thereby synchronously controlling the plurality of driving rollers to rotate together, and then driving the conveyor belt to operate, realizing the function of transporting electronic components. The suspension bracket is used to fix the guide frame, so that the guide frame hangs above the steering wheel.

[0013] Preferably, the driving roller is arranged in a shape with wide ends and narrow middle. The cross-section of the conveyor belt is arranged in a shape with high ends and low middle. Such a shape setting of the conveyor belt enables the electronic components falling on the conveyor belt to move to the middle under the action of gravity, which not only facilitates the detection process, but also ensures the smooth switching process between the conveyor belt and the steering wheel during central transportation.

[0014] Preferably, a vacuum pump is fixedly connected to the outside of the support frame. The negative pressure end of the vacuum pump is located in the middle of the support frame. The outer edge of the conveyor belt fits with the edge of the support frame. There is a gap between adjacent driving rollers. Adsorption holes penetrating to the bottom surface are formed on the surface of the conveyor belt. In order to ensure the stability of the electronic components during the detection process and reduce the influence of shaking on the detection process, negative pressure is transmitted into the interior of the support frame through the vacuum pump, and the negative pressure will be transmitted to the surface of the conveyor belt through the adsorption holes, thereby adsorbing the electronic components on the surface and reducing the shaking caused by mechanical operation, thus reducing the influence on the detection process. The vacuum pump is located in the middle of the support frame. The negative pressure is weaker at both ends of the conveyor belt and cannot adsorb the electronic components. Therefore, the electronic components can fall into the steering wheel from the ends. When at the middle detection part, they are firmly adsorbed, reducing the influence brought by vibration.

[0015] Preferably, a liftable blocking plate is arranged above the conveyor belt. Two parallel electric telescopic rods I are fixedly connected to the top of the blocking plate. The bottom surface shape of the blocking plate fits the top surface shape of the conveyor belt. The blocking plate is controlled to lift by the electric telescopic rod I. The blocking plate can block the advancing electronic components and periodically rise to allow the electronic components to move forward normally. Through the setting of the blocking plate, even if there are some deviations in the feeding process or the transfer process of the steering wheel, the subsequent electronic components can be prevented from affecting the detection process of the previous electronic component by the blocking of the blocking plate.

[0016] Preferably, a laser detector is fixedly connected to the middle of the baffle. The emitting end of the laser detector is located on the bottom surface of the baffle, and the emitting end of the laser detector is arranged in a long strip shape. When the baffle rises, the laser detector will emit detection laser from the bottom of the baffle, and can scan whether the electronic components pass normally. If no electronic components are scanned, it means that the device has a fault. At this time, the laser detector will send out a fault signal to remind the maintenance personnel.

[0017] The beneficial effects of the present invention are as follows: 1. For the electronic component finished product yield detection device of the present invention, through the setting of the optical camera and two conveyor belts, the conveyor belts are used to transport the electronic components, so that the electronic components and the optical camera move and observe synchronously; through this setting, the surface of the electronic components can be effectively observed and detected, and the defects existing on the surface of the electronic components can be fully detected. Only in a very small probability, during two detections, the defective parts are in positions that cannot be detected by the optical camera; and during the detection process, the electronic components are always in a moving and transporting state, and there is no need to stop the conveyor belt for detection. Not only does it improve the detection efficiency, but also when the conveyor belt stops, the electronic components will shake under the action of inertia, which is likely to cause inaccurate detection. This method effectively improves the detection accuracy; at the same time, the entire device is purely mechanically controlled without manual assistance, effectively reducing the labor cost.

[0018] 2. For the electronic component finished product yield detection device of the present invention, the steering wheel is located between the two conveyor belts. After the electronic components that have undergone one detection fall from the end of the conveyor belt onto the steering wheel, as the steering wheel rotates, the electronic components will be transferred above the other conveyor belt and finally fall onto the other conveyor belt. The surface of the steering wheel is covered with a flexible pad, and the impact of the fall will not affect the electronic components. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0022] As Figures 1 to 5 shown, a finished product yield detection device for electronic components according to an embodiment of the present invention includes two conveyor belts 1, the two conveyor belts 1 are arranged in parallel, a steering wheel 5 is arranged between one ends of the two conveyor belts 1, and the steering wheel 5 is used for transporting the electronic components transported on the two conveyor belts 1. An electric slide rail 2 is arranged above the conveyor belt 1. The electric slide rail 2 is arranged in a rectangle, and two of the sides of the rectangle are parallel to the length directions of the two conveyor belts 1. An optical camera 8 is installed on the moving end of the electric slide rail 2, and the observation position of the optical camera 8 is located on the upper surfaces of the two conveyor belts 1; Through the setting of the optical camera 8 and the two conveyor belts 1, the electronic components to be detected are placed on one of the conveyor belts 1. When the electronic components move to the observation area of the optical camera 8, the conveyor belt 1 still keeps transporting. At the same time, the electric slide rail 2 controls the horizontal movement of the optical camera 8, and the moving speed is the same as the speed and direction of the conveyor belt 1. At this time, the optical camera 8 can keep relatively stationary with the electronic components, so as to observe whether there are defects on the surface of the electronic components. As the electronic components continue to move forward, they will fall from the end of the conveyor belt 1 into the steering wheel 5, and the electronic components are transferred to the other conveyor belt 1 through the rotation of the steering wheel 5. Since the electric slide rail 2 is arranged in a ring shape, and two of the sides of the electric slide rail 2 are parallel to the two conveyor belts 1, the optical camera 8 can be moved above the other conveyor belt 1. When the conveyor belt 1 transfers the electronic components that have been detected once to the position where they can be detected by the optical camera 8, the optical camera 8 moves synchronously and in the same direction with the conveyor belt 1 again, so that the optical camera 8 observes the electronic components synchronously again. Because the electronic components have changed their postures after experiencing the rotational transfer of the steering wheel 5, observing the electronic components again can detect the parts that were not detected during the previous detection process. A sorting device is arranged at the tail of the other conveyor belt 1. The optical camera 8 transmits the detected signal to the sorting device, and different types of finished products can be sorted. Through this setting, the surface of the electronic components can be effectively observed and detected, and the defects existing on the surface of the electronic components can be fully detected. Only in a very small probability, during the two detections, the defective parts are always in the positions that cannot be detected by the optical camera 8. And during the detection process, the electronic components are always in a moving and transporting state, and there is no need to stop the conveyor belt 1 for detection. This not only improves the detection efficiency, but also when the conveyor belt 1 stops, the electronic components will shake under the action of inertia, which is likely to cause inaccurate detection. This method effectively improves the detection accuracy. At the same time, the whole device is purely mechanically controlled without manual assistance, effectively reducing the labor cost.

[0023] The two conveyor belts 1 are arranged in a high-low staggered manner. The steering wheel 5 is arranged between the two conveyor belts 1. A driving motor 6 for driving the rotation of the steering wheel 5 is arranged at the bottom of the steering wheel 5. A guiding frame 19 for guiding the movement of the electronic components is arranged above the steering wheel 5. During operation, the steering wheel 5 is located between the two conveyor belts 1. After the electronic components that have undergone one inspection fall from the end of the conveyor belt 1 onto the steering wheel 5, as the steering wheel 5 rotates, the electronic components will be transferred above the other conveyor belt 1 and finally fall onto the other conveyor belt 1. The surface of the steering wheel 5 is covered with a flexible pad, and the impact of the fall will not affect the electronic components. The setting of the guiding frame 19 is to ensure that the electronic components can accurately move onto the other conveyor belt 1. Since the electronic components have experienced two falls and the rotational transportation of the steering wheel 5, their self-orientation has been greatly changed, ensuring that both inspections can cover the entire outer surface of the electronic components. The electronic components with a very low probability of insufficient inspection can be ignored.

[0024] The optical camera 8 is inclined. The mobile end of the electric slide rail 2 is fixedly connected with a moving seat 16. An adjustment frame 17 is installed below the moving seat 16. The two ends at the bottom of the adjustment frame 17 are horizontally arranged, and an adjustment motor is installed at the bottom end of the adjustment frame 17. The output end of the adjustment motor is fixedly connected to the outside of the optical camera 8. A plurality of electric telescopic rods two 15 for adjusting the height of the electric slide rail 2 are fixedly connected to the top of the electric slide rail 2; During operation, the inclined optical camera 8 observes the electronic components from an oblique upper position. Compared with observing from directly above, more sides of the electronic components can be observed. By rotating the adjustment motor, the inclination angle of the optical camera 8 can be controlled. At the same time, the electric telescopic rod two 15 can also control the lifting of the electric slide rail 2, enabling the optical camera 8 to observe the electronic components at the best angle when facing electronic components of different volumes.

[0025] There are two mobile ends of the electric slide rail 2, and both mobile ends are connected to the moving seat 16. A drive motor two 18 for controlling the rotation of the adjustment frame 17 is installed between the moving seat 16 and the adjustment frame 17; During operation, to further improve the inspection efficiency, two optical cameras 8 can be used to work in coordination. After the electronic components are inspected by the first optical camera 8, the subsequent inspection is handed over to the second optical camera 8. Then, the pictures taken twice are integrated. In this way, it is not necessary to wait for one electronic component to be inspected before placing a new one for inspection. Instead, the electronic components can be placed at a uniform speed for inspection. Since the placement speed is the same, it can be calculated when the electronic components will reach the shooting position of the second optical camera 8, so that the corresponding second photo can be accurately found to ensure the smooth progress of the inspection. The drive motor two 18 is used to adjust the orientation of the optical camera 8 to adapt to the installation process of the two optical cameras 8.

[0026] The guiding frame 19 is composed of two arc-shaped plates 21. The bottom surface of the arc-shaped plate 21 is in sliding fit with the top surface of the steering wheel 5. A guiding channel is formed between the two arc-shaped plates 21. The two ends of the channel are respectively adapted to the two ends of the two conveyor belts 1. A suspension bracket 7 is fixedly connected above the arc-shaped plate 21, and the suspension bracket 7 is fixedly connected to the conveyor belt 1; During operation, when electronic components fall above the steering wheel 5, they will be restricted in the guiding channel. Then, as the steering wheel 5 rotates, the electronic components will enter the second conveyor belt 1 accurately along the guiding channel, thus ensuring the smooth progress of the detection process. Moreover, the whole structure is simple and convenient, reducing the failure rate, and can smoothly transfer electronic components with different volumes and shapes. By adjusting the rotation speed of the steering wheel 5, the speed of transferring electronic components can be adjusted, and the operation is also very convenient.

[0027] The conveyor belt 1 includes a support frame 10. A plurality of driving rollers are arranged in the middle of the support frame 10. A conveyor belt 13 is sleeved outside the plurality of driving rollers. A power box 11 capable of simultaneously driving the plurality of driving rollers to rotate is installed at one end of the support frame 10 away from the steering wheel 5. The suspension bracket 7 is fixedly connected to the support frame 10; During operation, a servo motor is arranged in the power box 11. A transmission shaft is connected between one ends of the plurality of driving rollers. The servo motor drives the transmission shaft to rotate, thereby synchronously controlling the plurality of driving rollers to rotate together, and then driving the conveyor belt 13 to operate, realizing the function of transporting electronic components. The suspension bracket 7 is used to fix the guiding frame 19 and suspend the guiding frame 19 above the steering wheel 5.

[0028] The driving roller is arranged in a shape with wide ends and narrow middle, and the cross-section of the conveyor belt 13 is arranged in a shape with high ends and low middle; During operation, the shape setting of the conveyor belt 13 enables the electronic components falling on the conveyor belt 13 to move to the middle under the action of gravity, which not only facilitates the detection process, but also ensures the smooth progress of the switching process between the conveyor belt 1 and the steering wheel 5 during central transportation.

[0029] A vacuum pump 3 is fixedly connected to the outside of the support frame 10. The negative pressure end of the vacuum pump 3 is located in the middle of the support frame 10. The outer edge of the conveyor belt 13 is attached to the edge of the support frame 10. There is a gap between adjacent driving rollers. Adsorption holes 14 penetrating to the bottom surface are formed on the surface of the conveyor belt 13; During operation, to ensure the stability of electronic components during the detection process and reduce the impact of shaking on the detection process, a negative pressure is transmitted into the interior of the support frame 10 through the vacuum pump 3. The negative pressure is transmitted to the surface of the conveyor belt 13 through the adsorption holes 14, thereby adsorbing the electronic components on the surface, reducing the shaking caused by mechanical operation, and thus reducing the impact on the detection process. The vacuum pump 3 is located in the middle of the support frame 10. The negative pressure is weak at both ends of the conveyor belt 1, and the electronic components cannot be adsorbed. Therefore, the electronic components can fall into the steering wheel 5 from the ends. When at the middle detection position, they are firmly adsorbed, reducing the impact caused by vibration.

[0030] Above the conveyor belt 1, there is a blocking plate 4 that can be lifted and lowered. At the top of the blocking plate 4, two parallel electric telescopic rods 9 are fixedly connected. The bottom surface shape of the blocking plate 4 fits the top surface shape of the conveyor belt 13. During operation, the blocking plate 4 is controlled to lift and lower through the electric telescopic rod 9. The advancing electronic components can be blocked by the blocking plate 4 and periodically lifted, allowing the electronic components to move forward normally. Through the setting of the blocking plate 4, even if there are some deviations during the feeding process or the transfer process of the steering wheel 5, the subsequent electronic components can be prevented from affecting the detection process of the previous electronic component through the blocking of the blocking plate 4.

[0031] In the middle of the blocking plate 4, a laser detector 20 is fixedly connected. The emitting end of the laser detector 20 is located on the bottom surface of the blocking plate 4, and the emitting end of the laser detector 20 is arranged in a long strip shape. During operation, when the blocking plate 4 rises, the laser detector 20 emits detection laser from the bottom of the blocking plate 4, and can scan whether the electronic components pass normally. If no electronic components are scanned, it means that the device has a malfunction. At this time, the laser detector 20 will send out a malfunction signal to remind the maintenance personnel.

[0032] During operation: With the optical camera 8 and the two conveyor belts 1 arranged, the electronic components to be inspected are placed on one of the conveyor belts 1. When the electronic components move to the observation area of the optical camera 8, the conveyor belt 1 continues to operate for transportation. At the same time, the electric slide rail 2 controls the horizontal movement of the optical camera 8, and the moving speed is the same as the speed and direction of the conveyor belt 1. At this time, the optical camera 8 can remain relatively stationary with the electronic components, so as to observe whether there are defects on the surface of the electronic components. As the electronic components continue to move forward, they will fall from the end of the conveyor belt 1 into the turntable 5. Through the rotation of the turntable 5, the electronic components are transferred to the other conveyor belt 1. Since the electric slide rail 2 is arranged in a ring shape, and two of the sides of the electric slide rail 2 are parallel to the two conveyor belts 1, the optical camera 8 can be moved above the other conveyor belt 1. When the conveyor belt 1 transfers the electronic components that have been inspected once to a position where they can be detected by the optical camera 8, the optical camera 8 moves synchronously and in the same direction as the conveyor belt 1 again, so that the optical camera 8 can observe the electronic components synchronously again. Since the electronic components have changed their postures after experiencing the rotational transfer of the turntable 5, observing the electronic components again can detect the parts that were not detected during the previous inspection. A sorting device is arranged at the tail of the other conveyor belt 1. The optical camera 8 transmits the detected signal to the sorting device, and different types of finished products can be sorted. Through this arrangement, the surface of the electronic components can be effectively observed and detected, and the defects existing on the surface of the electronic components can be fully detected. Only in a very small probability, during the two detections, the defective parts are all in positions that cannot be detected by the optical camera 8. And during the detection process, the electronic components are always in a moving and transporting state, and there is no need to stop the conveyor belt 1 for detection. This not only improves the detection efficiency, but also when the conveyor belt 1 stops, the electronic components will shake under the action of inertia, which is likely to cause inaccurate detection. This method effectively improves the detection accuracy. At the same time, the entire device is purely mechanically controlled and does not require manual assistance, effectively reducing the labor cost; The turntable 5 is located between the two conveyor belts 1. After the electronic components that have undergone one detection fall from the end of the conveyor belt 1 onto the turntable 5, as the turntable 5 rotates, the electronic components will be transferred above the other conveyor belt 1 and finally fall onto the other conveyor belt 1. The surface of the turntable 5 is covered with a flexible pad, and the falling impact will not affect the electronic components. The guiding frame 19 is arranged to ensure that the electronic components can accurately move onto the other conveyor belt 1. Since the electronic components have experienced two drops and the rotational transportation of the turntable 5, their self-orientations have been greatly changed, ensuring that the outer surfaces of the electronic components can be fully detected in the two detections. The electronic components with insufficient detection in a very small probability can be ignored; The tilted optical camera 8 observes the electronic components from an oblique upper position. Compared with observing from directly above, more sides of the electronic components can be observed. By adjusting the rotation of the motor, the tilt angle of the optical camera 8 can be controlled. At the same time, the electric telescopic rod two 15 can also control the lifting of the electric slide rail 2, enabling the optical camera 8 to observe the electronic components at the best angle when facing electronic components of different volumes; To further improve the detection efficiency, two optical cameras 8 can be used to work in coordination. After the electronic components are detected by the first optical camera 8, the subsequent detection is handed over to the second optical camera 8. Then, the pictures taken twice are integrated. In this way, there is no need to wait for one electronic component to be detected and then place a new one for detection. Instead, electronic components can be placed at a uniform speed for detection. Since the placement speed is the same, it is possible to calculate when the electronic components will reach the shooting position of the second optical camera 8, so that the corresponding second photo can be accurately found to ensure the smooth progress of the detection. The drive motor two 18 is used to adjust the orientation of the optical camera 8 to adapt to the installation process of the two optical cameras 8; When the electronic components fall above the steering wheel 5, they will be restricted in the guiding channel. Then, as the steering wheel 5 rotates, the electronic components will enter the guiding channel and accurately fall onto the second conveyor belt 1, thereby ensuring the smooth progress of the detection process. Moreover, the entire structure is simple and convenient, reducing the failure rate, and can smoothly transfer electronic components of different volumes and shapes. By adjusting the rotation speed of the steering wheel 5, the speed of transferring electronic components can be adjusted, and the operation is also very convenient; A servo motor is provided in the power box 11. A transmission shaft is connected between one ends of multiple driving rollers. The servo motor drives the transmission shaft to rotate, thereby synchronously controlling the rotation of multiple driving rollers together, and then driving the conveyor belt 13 to operate to achieve the function of transporting electronic components. The suspension bracket 7 is used to fix the guiding frame 19, so that the guiding frame 19 is suspended above the steering wheel 5; The shape setting of the conveyor belt 13 enables the electronic components falling on the conveyor belt 13 to move to the middle under the action of gravity, which not only facilitates the detection process, but also ensures the smooth switching process between the conveyor belt 1 and the steering wheel 5; To ensure the stability of the electronic components during the detection process and reduce the impact of shaking on the detection process, negative pressure is transmitted into the interior of the support frame 10 through the vacuum pump 3. The negative pressure will be transmitted to the surface of the conveyor belt 13 through the adsorption holes 14, thereby adsorbing the electronic components on the surface, reducing the shaking caused by mechanical operation, and thus reducing the impact on the detection process. The vacuum pump 3 is located in the middle of the support frame 10. The negative pressure is weaker at both ends of the conveyor belt, and the electronic components cannot be adsorbed. Therefore, the electronic components can fall into the steering wheel 5 from the ends. At the middle detection part, the adsorption is firm, reducing the impact of vibration; The baffle plate 4 is controlled to lift by the electric telescopic rod 1, and the baffle plate 4 can block the advancing electronic components and periodically rise to allow the electronic components to move forward normally. With the setting of the baffle plate 4, even if there are some deviations in the feeding process or the transfer process of the steering wheel 5, the baffle plate 4 can block them to ensure that the electronic components behind do not affect the detection process of the previous electronic component; When the baffle plate 4 rises, the laser detector 20 will emit detection laser from the bottom of the baffle plate 4 to scan whether the electronic components pass normally. If no electronic components are scanned, it means that the device has a fault. At this time, the laser detector 20 will send out a fault signal to remind the maintenance personnel.
