Description

Technical Field

[0001] This utility model relates to the field of coil testing, and more specifically, to a coil testing device. Background Technology

[0002] Coils are a commonly used electronic component in electronics technology, with a wide range of important functions. They are used in quality control, performance evaluation, and troubleshooting during the production process. With the rapid development of electronic technology, coils are key components in electronic devices and systems, and the stability and reliability of their performance are crucial to the normal operation of the entire system.

[0003] During the testing of a coil, it is necessary to test the inductance coefficient of the coil. The coil is placed on an AC circuit, and the inductance value of the coil under test is calculated based on the number of indications of each knob. Occasionally, due to various factors, the coil may not make good contact with the circuit when it is placed on the AC circuit, resulting in inaccurate measurement results.

[0004] Therefore, a new technical solution is needed to address the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a coil detection device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a coil detection device, including a base, a detection device and a transport platform are installed on the top of the base, one end of the detection device is located below the transport platform, the transport platform is connected to a fixed block placed on the upper end of the transport platform by a power device, a coil is detachably connected to the upper end of the fixed block, and the two ends of the winding of the coil extend to the bottom end of the fixed block.

[0007] By adopting the above technical solution, this device mainly consists of a base, with a detection device and a transport platform mounted on the upper part of the base. The transport platform transports the fixed block from one end to the other. A coil is mounted on the fixed block. As the fixed block moves the coil from one end of the transport platform to the other, it passes the detection device located at the bottom of the transport platform. When the fixed block moves the coil to the upper part of the detection device, the winding at the bottom of the fixed block contacts the detection device, and the inductance coefficient of the coil is detected. The fixed block is used to fix the coil winding to prevent detection deviation caused by poor coil contact.

[0008] The present invention is further configured such that: the fixing block has two through holes extending through the upper and lower ends, and the winding passes through the through holes from the top of the fixing block and is located at the bottom of the fixing block.

[0009] By adopting the above technical solution, the winding abuts against the detection device through the through hole opened in the fixing block. When the fixing block moves, the winding will not be affected, and only the bottom end will contact the detection device for detection.

[0010] The present invention is further configured such that: the detection device includes an AC power supply and a circuit, the AC power supply is installed inside the detection device, the circuit is fixedly connected to the AC power supply, and the circuit extends to the position below the transport platform.

[0011] By adopting the above technical solution, the detection device uses current to measure a series of coefficients of the coil, and then calculates the inductance. When the AC power supply releases current into the circuit, and the current flows through the circuit, the coefficients of the coil can be detected in the detection device when the winding comes into contact with the circuit.

[0012] The present invention is further configured such that: the rotating column is equipped with a toothed angle, the conveyor belt is provided with a toothed track, and the toothed angle rotates with the toothed track gear.

[0013] By adopting the above technical solution, the rotating column and the conveyor belt rotate through gears, the fixed block is placed at the top of the conveyor belt, and the bottom end of the fixed block abuts against the top of the conveyor belt. The rotation of the gears causes the conveyor belt to rotate forward, which can drive the fixed block to move forward stably.

[0014] The present invention is further configured such that the bottom end of the center position of the transport platform is concave downward, and the concave position is the same as the circuit position.

[0015] By adopting the above technical solution, the fixed block can be moved downward at the concave angle, so that the winding at the lower end of the fixed block comes into contact with the circuit in the detection device, allowing the detection device to measure it.

[0016] The present invention is further configured such that the AC power source generates alternating current.

[0017] By adopting the above technical solution, the winding is measured using alternating current, and the various coefficients of the coil are measured using the alternating current bridge method.

[0018] The present invention is further configured such that: two slots are fixedly connected to the bottom end of the fixing block, and the slots are L-shaped and mirror-opposite.

[0019] By adopting the above technical solution, the slot is designed in an L-shape, and the gap between the bend and the bottom of the fixed block is embedded in the conveyor belt, so that the fixed block can move more stably when the conveyor belt rotates and moves forward.

[0020] In summary, this utility model has the following beneficial effects: the winding is inserted through the hole in the fixing block, and the bottom end of the winding abuts against the circuit in the detection device. The released AC current energizes the coil, and the coefficient is detected to complete the detection of the coil inductance, which can effectively reduce the problem of poor coil contact.

[0027] A coil detection device such as Figure 1 As shown, a coil testing device includes a base 1, characterized in that: a testing device 2 and a transport platform 3 are installed on the top of the base 1, one end of the testing device 2 is located below the transport platform 3, the transport platform 3 is powered by a power device, a fixing block 4 is placed on the upper end of the transport platform 3, a coil 5 is detachably connected to the upper end of the fixing block 4, and the two ends of the winding 51 of the coil 5 extend to the bottom end of the fixing block 4.

[0028] like Figure 2 As shown, the rotating column 32 is equipped with a toothed angle, and the conveyor belt 31 is provided with a toothed track. The toothed angle and the toothed track gear rotate. The bottom of the center position of the transport table 3 is concave downward, and the concave position is the same as the circuit position.

[0029] like Figure 3 As shown, the fixing block 4 has two through holes that pass through both the top and bottom ends. The winding 51 passes through the through holes from the top of the fixing block 4 and is located at the bottom of the fixing block 4. The bottom of the fixing block 4 is fixedly connected to two slots 41, which are L-shaped and mirror-shaped.

[0031] This device mainly consists of a base 1 as the base, with a detection device 2 and a transport platform 3 installed on the upper end of the base 1. The transport platform 3 includes a rotating column 32 and a conveyor belt 31. The rotating column 32 and the conveyor belt 31 are connected by gears. The fixed block 4 is placed on the top of the conveyor belt 31. The slot 41 at the bottom of the fixed block 4 is designed to be L-shaped. The gap between the bend of the slot 41 and the bottom of the fixed block 4 is embedded in the conveyor belt 31. When the bend moves to the rotating column 32, there is a distance between the two, so there will be no collision. After the fixed block 4 is connected to the conveyor belt 31, the gear rotates and the conveyor belt 31 rotates forward, which can drive the fixed block 4 to move forward stably. The transport platform 3 transports the fixed block 4 from one end to the other end. A coil 5 is mounted on the fixing block 4. The winding 51 abuts against the detection device 2 through a through hole in the fixing block 4. When the fixing block 4 moves, the winding 51 is not affected; only its bottom end contacts the detection device 2 for detection. As the fixing block 4 moves the coil 5 from one end of the transport platform 3 to the other, it passes the detection device 2 located at the bottom of the transport platform 3. The detection device 2 includes an AC power supply 21 and a circuit 22. The AC power supply 21 applies AC current to the circuit 22. The winding 51 located at the bottom of the fixing block 4 contacts the detection device 2.

[0032] Circuit 22 makes contact and detects the inductance coefficient of coil 5. Fixing block 4 is used to fix the winding 51 of coil 5 to prevent detection deviation caused by poor contact of coil 5.
