Description

Technical Field

[0001] The utility model relates to the technical field of diode testing, in particular to an automatic diode testing mechanism. Background Art

[0002] In the prior art, to test the quality of a diode: after fixing and positioning the diode, a multimeter is taken, adjusted, and held with one hand on the red test lead and the other on the black test lead. The red and black test leads are simultaneously brought into contact with the positive and negative electrodes of the diode, and then the operation is reversed. If the diode conducts once and cuts off once, it indicates that the diode is normal.

[0003] However, for such testing means, the diode needs to be pre-positioned first, and then the multimeter is taken and operated twice. When batch testing diodes, the detection efficiency is low. Therefore, a new automatic diode testing mechanism is designed to simplify the testing operation and quickly test a large number of diodes. Summary of the Utility Model

[0004] The purpose of the utility model aims to solve at least one of the technical defects.

[0005] For this reason, an object of the utility model is to provide an automatic diode testing mechanism to solve the problems mentioned in the background art and overcome the deficiencies in the prior art.

[0006] To achieve the above object, an embodiment of one aspect of the utility model provides an automatic diode testing mechanism, including a frame, a motor, and a chain plate. A motor is fixedly connected to the outside of the frame, the motor is installed horizontally, a chain plate is movably connected to the inside of the frame, a sprocket at the output end of the motor drives a chain and the chain plate to rotate, and a sleeve is fixedly connected to the outer surface of each chain plate;

[0007] Both ends of the sleeve are through structures, and the top of the sleeve has an opening;

[0008] A diode is clamped inside the sleeve;

[0009] Two groups of brackets are fixedly connected to the top of the frame, an electric meter is fixedly connected to the top of the brackets, the bottom end of the electric meter is connected with a red test post and a black test post through wires, the red test posts and black test posts of the two electric meters are arranged oppositely, and the bottom ends of the red test post and the black test post are fixedly connected with a touch plate;

[0010] The touch plate is inclined, and the middle section of the touch plate is movably connected to the top surface of the frame through a rotating shaft;

[0011] A vertical plate is fixedly connected to the top of the frame, and a tension spring is connected between the vertical plate and the end of the touch plate.

[0012] Preferably, according to any of the above solutions, the sleeve is adhesively bonded to the link plate, and the sleeve is made of plastic.

[0013] Adopting the above technical solution: This mechanism is dedicated to the testing and detection of ordinary, i.e., round tube-shaped diodes, for quickly testing their quality. It can perform automatic testing, and only manual assistance is required for loading and unloading the diodes.

[0014] Preferably, according to any of the above solutions, the diode is arranged horizontally, and the pins at both ends of the diode are movably connected to the inner side of the touch plate.

[0015] Adopting the above technical solution: The key point of using this mechanism is that when manually inserting the diode into the inner side of the plastic sleeve, it needs to be placed in the center, and the positive electrode placement direction of the diodes should be the same.

[0016] Preferably, according to any of the above solutions, the model of the ammeter is MY61.

[0017] Adopting the above technical solution: This ammeter is a common one for testing the quality of diodes.

[0018] Preferably, according to any of the above solutions, the touch plate is made of copper. The distance between the connection end of the touch plate and the tension spring in the same group is greater than that at the other end. When the diode passes through the inner side of the touch plate, one end of the touch plate expands outward under the action of the pins.

[0019] Adopting the above technical solution: The core structure of this mechanism is: motor, link plate, sleeve, bracket, ammeter, red meter column, black meter column, touch plate, vertical plate, and tension spring. The core advantages of this mechanism are: it can perform fast and automatic testing on diodes, and is a flow-through testing, which can quickly test their quality and improve the testing efficiency; specifically, two sets of testing devices are designed, consisting of a bracket, an ammeter, a red meter column, a black meter column, a touch plate, a vertical plate, and a tension spring. In the two sets of testing devices, the red meter columns and black meter columns of the two ammeters are designed to be opposite. In this way, when the diode passes through, its positive electrode will first contact the red meter column of the first set of ammeters and then the black meter column of the second set of ammeters, and its negative pin will first contact the black meter column of the first set of ammeters and then the red meter column of the second set of ammeters. The touch plates are arranged in a V-shaped layout to ensure that the diode can smoothly enter the inner side of the touch plate. Subsequently, the inner side of the touch plate becomes narrower to ensure that the pins of the diode can better contact the touch plate. At this time, the narrow opening of the touch plate is expanded outward, the tension spring stretches, and after the diode completely passes through, the touch plate resets;

[0020] The test principle is as follows: When the diode passes through the first test device, i.e., the ammeter, the positive pin contacts the red terminal of the ammeter through the contact plate, and the negative pin contacts the black terminal of the ammeter through the contact plate. The ammeter is set to the diode range. At this time, there will be a digital voltage drop on the ammeter. Then, when the diode passes through the second test device, i.e., another set of ammeters, the positive pin contacts the black terminal of the ammeter through the contact plate, and the negative pin contacts the red terminal of the ammeter through the contact plate. At this time, if the ammeter does not show a reading, it indicates that this diode conducts normally in the forward direction and cuts off in the reverse direction, and it is a normal diode. After the test is completed, the diode can be taken out from the sleeve.

[0021] Preferably, according to any of the above solutions, the tension spring is arranged horizontally.

[0022] Compared with the prior art, the advantages and beneficial effects of the present utility model are as follows:

[0023] Through the coordinated setting of the motor, chain plate, sleeve, bracket, ammeter, red terminal, black terminal, contact plate, vertical plate and tension spring, the automatic testing mechanism for diodes designs a dedicated flow-through testing mechanism for diodes, which can quickly and automatically test diodes. And for flow-through testing, it can quickly test their quality, improving the testing efficiency. The whole process only requires manual assistance to pick up and place the diodes.

The bottom end of the ammeter 7 is connected with a red test lead 8 and a black test lead 9 through wires. The red test leads 8 and black test leads 9 of the two ammeters 7 are arranged oppositely. The bottom ends of the red test lead 8 and the black test lead 9 are fixedly connected with a touch plate 10;

[0036] The touch plate 10 is inclined, and the middle section of the touch plate 10 is movably connected to the top surface of the frame 1 through a rotating shaft;

[0037] A vertical plate 11 is fixedly connected to the top of the frame 1, and a tension spring 12 is connected between the vertical plate 11 and the end of the touch plate 10.

[0038] Embodiment 1: The sleeve 4 is bonded to the chain plate 3, and the material of the sleeve 4 is plastic. This mechanism is dedicated to the testing and detection of ordinary type, that is, round tube type diodes 5, to quickly test their quality, and can be automatically tested. Only manual assistance is required to pick up and place the diodes 5. The diode 5 is arranged horizontally, and the pins at both ends of the diode 5 are movably connected to the inside of the touch plate 10. The key point of using this mechanism is that when manually clamping the diode 5 into the inside of the plastic sleeve 4, it needs to be placed in the center, and the positive pole placement directions of the diodes 5 should be the same.

[0039] Embodiment 2: The model of the electric meter 7 is MY61. This electric meter 7 is a common electric meter for testing the quality of the diode 5. The touch plate 10 is made of copper. The distance between the connection end of the same group of touch plates 10 and the tension spring 12 is greater than that of the other end. When the diode 5 passes through the inner side of the touch plate 10, one end of the touch plate 10 expands outward under the action of the pin. The tension spring 12 is arranged horizontally.

[0040] The working principle of the present utility model is as follows:

[0041] S1. Specifically, two groups of test devices are designed, which are composed of a bracket 6, an electric meter 7, a red terminal 8, a black terminal 9, a touch plate 10, a vertical plate 11 and a tension spring 12. In the two groups of test devices, the red terminals 8 and black terminals 9 of the two electric meters 7 are designed to be opposite. In this way, when the diode 5 passes through, its positive electrode will first contact the red terminal 8 of the first group of electric meters 7 and then contact the black terminal of the second group of electric meters 7. Its negative electrode pin will first contact the black terminal 9 of the first group of electric meters 7 and then contact the red terminal 8 of the second group of electric meters 7. The touch plates 10 are designed to be arranged in a figure-eight shape to ensure that the diode 5 can smoothly enter the inner side of the touch plate 10. Subsequently, the inner side of the touch plate 10 becomes narrower to ensure that the pins of the diode 5 can better contact the touch plate 10. At this time, the narrow opening of the touch plate 10 is expanded outward, and the tension spring 12 extends. After the diode 5 completely passes through, the touch plate 10 resets;

[0042] S2. Manually place the diode 5 into the sleeve 4. When the diode 5 passes through the first test device, that is, the electric meter 7, the positive electrode pin contacts the red terminal 8 through the touch plate 10, and the negative electrode pin contacts the black terminal 9 through the touch plate 10. The electric meter 7 is in the diode gear. At this time, the electric meter 7 will have a digital voltage drop. Then, when the diode 5 passes through the second test device, that is, another group of electric meters 7, the positive electrode pin contacts the black terminal 9 through the touch plate 10, and the negative electrode pin contacts the red terminal 8 through the touch plate 10. At this time, the electric meter 7 does not display, indicating that this diode 5 is normally forward-conducting and reverse-blocking, and is a normal diode 5. After the test is completed, the diode 5 can be taken out from the sleeve 4.
