Description

Technical Field

[0001] This utility model relates to the field of sorting machine technology, and in particular to a test sorting machine with image detection. Background Technology

[0002] The Hall effect is a type of magnetoelectric effect. When a current flows through a conductor located in a magnetic field in a direction perpendicular to the external magnetic field, a potential difference appears between the two ends of the conductor perpendicular to both the magnetic field and the current direction. This phenomenon is called the Hall effect. A Hall sensor is a sensor that uses a Hall element based on the Hall effect principle to convert a measured physical quantity (such as current, magnetic field, displacement, pressure, etc.) into an electromotive force output. Hall devices are simple in structure, small in size, contactless, highly reliable, and easily miniaturized, thus finding wide application in measurement technology.

[0003] To ensure the accuracy of Hall elements, each Hall element on the Hall plate needs to be tested, such as for offset calibration and gain calibration. This requires generating a current in the vias of the Hall elements, which is produced by the corresponding testing instrument. Current technology typically uses a test sorting machine to perform performance testing on Hall devices. This involves electrically connecting the Hall elements, manufactured through a predetermined process, to the test machine and directly classifying the semiconductor devices based on the test results. This effectively overcomes the inefficiency of manual sorting in traditional technology. However, current test sorting machines cannot inspect the appearance of the Hall elements, leading to some damaged elements being mixed into the finished raw materials, thus reducing sorting efficiency. To address these issues, a solution is proposed below. Utility Model Content

[0004] The purpose of this invention is to provide a test and sorting machine with image detection, which has the advantages of being able to detect the integrity of the outer surface of Hall elements and having high detection and sorting efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A testing and sorting machine with image detection includes a frame, a mounting base fixed to the upper end of the frame, a vibrating plate mounted on the upper end of the mounting base, a support fixed to the upper end of the frame, a transmission track mounted on the top of the support, a detection port opened on the upper side of the transmission track, an image frame fixed to one side of the transmission track, an image device mounted on the image frame and positioned above the detection port, a material stop block passing through the lower side of the transmission track, a material stop cylinder positioned below the transmission track, and the output shaft of the material stop cylinder being fixedly connected to the lower end of the material stop block, a mounting plate fixed to one side of the frame, two mounting brackets fixed to the upper end of the mounting plate, a first magnetic field and a second magnetic field respectively mounted on the two mounting brackets, and a discharge mechanism positioned below the transmission track on the lower side of the frame.

[0007] Preferably, the discharge mechanism includes a discharge plate located below the mounting plate. A motor is installed at the lower end of the discharge plate, and a rotating frame is provided above the discharge plate. The output shaft of the motor passes through the discharge plate and is fixedly connected to the rotating frame. A distributing pipe is installed on the rotating frame, and a distributing rack is also fixedly provided on the discharge plate, with the distributing pipe cooperating with the distributing rack.

[0008] Preferably, a feeding plate is provided below the feeding plate, a connecting plate is connected between the feeding plate and the discharge plate, a feeding rack is fixed on the feeding plate, and a plurality of feeding slots are provided on the feeding rack.

[0009] Preferably, a controller is mounted on top of the rack.

[0010] Preferably, the first magnetic field and the second magnetic field are located on both sides of the bottom end of the transmission track.

[0011] The beneficial effects of this utility model are as follows: the Hall element can be conveyed by the vibratory feeder and transported to the transmission track. The baffle cylinder can drive the baffle block to move up and down. When the baffle block moves upward, it can block the Hall element being transported, thereby blocking the Hall element at the detection port, so that the outer surface of the Hall element can be detected. At this time, the appearance of the Hall element can be photographed by the imaging equipment, thereby realizing the inspection of the Hall element and preventing damaged Hall elements from being mixed in, thus improving the subsequent sorting efficiency of the Hall element. When the baffle block moves downward, it separates from the Hall element, and the normal transmission of the Hall element can be realized. After the appearance inspection is completed, the Hall element can be transported with the transmission track to the space between the first magnetic field and the second magnetic field. Then, the Hall element can be detected by the first magnetic field and the second magnetic field to ensure that the Hall element can be used normally. After the detection is completed, the Hall element can be sorted by the discharge mechanism. Attached Figure Description

[0018] like Figures 1 to 4As shown, a testing and sorting machine with image detection includes a frame 1.

A support 4 is also fixed to the upper end of the frame 1, and a transmission track 5 is mounted on the top of the support 4. Hall effect sensors can be transported via the vibratory feeder 3 and transported into the transmission track 5. A detection port 6 is opened on the upper side of the transmission track 5, and an image frame 7 is fixed to one side of the transmission track 5. An image device 8 is mounted on the image frame 7 and is located above the detection port 6. A baffle block 9 passes through the lower side of the transmission track 5, and a baffle cylinder 10 is located below the transmission track 5. Furthermore, the output shaft of the baffle cylinder 10 is fixedly connected to the lower end of the baffle block 9. The baffle cylinder 10 can drive the baffle block 9 to move up and down. When the baffle block 9 moves upward, it can block the Hall element being transmitted, thereby blocking the Hall element at the detection port 6, so that the Hall element can be inspected on its outer surface. At this time, the appearance of the Hall element can be photographed by the imaging device 8, thereby enabling the Hall element to be inspected to prevent damaged Hall elements from being mixed in, thereby improving the subsequent sorting efficiency of the Hall element. When the baffle block 9 moves downward, it separates from the Hall element, and the normal transmission of the Hall element can be realized.

[0019] A mounting plate 11 is fixedly installed on one side of the frame 1. Two mounting brackets 12 are fixedly installed on the upper end of the mounting plate 11. A first magnetic field 13 and a second magnetic field 14 are respectively installed on the two mounting brackets 12.

[0020] A discharge mechanism 15 is also provided on the lower side of the frame 1, and the discharge mechanism 15 is located below the conveying track 5. The Hall elements after testing can be sorted through the discharge mechanism 15. The discharge mechanism 15 includes a discharge plate 16, which is located below the mounting plate 11. A motor 17 is installed at the lower end of the discharge plate 16, and a rotating frame 18 is provided above the discharge plate 16. The output shaft of the motor 17 passes through the discharge plate 16 and is fixedly connected to the rotating frame 18. A distribution pipe 19 is installed on the rotating frame 18, and a distribution rack 20 is also fixed on the discharge plate 16. The distribution pipe 19 cooperates with the distribution rack 20. The rotation of the motor 17 can drive the rotating frame 18 to rotate, thereby driving the distribution pipe 19 to rotate. The operator can place several pipes at the distribution rack 20. When the Hall element falls into the distribution pipe 19, the rotation of the motor 17 can drive the distribution pipe 19 to rotate, transporting the Hall element one by one into each pipe for subsequent collection and processing.

[0021] Below the sorting plate is a feeding plate 21. A connecting plate 22 connects the feeding plate 21 to the discharge plate 16. A feeding rack 23 is fixed on the feeding plate 21.
