[0002] An inductor testing and sorting machine is an automated device specifically designed for the performance testing and sorting of inductors. In the electronics manufacturing industry, inductors, as crucial passive components, are widely used in various circuits, and their performance stability and consistency significantly impact the quality of electronic products. Therefore, accurate testing and efficient sorting of inductors are key steps in ensuring product quality and production efficiency.

[0003] Inductor testing and sorting machines are widely used in the electronics manufacturing industry, especially for products with stringent performance requirements for inductors, such as communication equipment, power modules, and automotive electronics. In these fields, inductor testing and sorting machines ensure the quality and consistency of inductors, improving product reliability and performance.

[0004] The design of inductor testing and sorting machines faces numerous challenges. Their complex structure contains many precision mechanical and electronic components, which are prone to wear due to friction and vibration during long-term operation. This wear not only affects the overall accuracy and stability of the equipment but may also shorten its lifespan and increase maintenance costs. Furthermore, the complexity of the structural design limits the processing efficiency of inductor testing and sorting machines, making it difficult to achieve high production rates while maintaining testing accuracy, thus hindering the improvement of production efficiency.

[0005] In view of this, the present invention provides an inductor testing and sorting machine to solve the problem that the automatic edge cutting device is prone to structural wear, which affects the overall production line efficiency. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an inductor testing and sorting machine, comprising:

[0007] The sorting machine assembly includes a sorting machine cabinet located at the bottom, a support plate connected to the upper surface of the sorting machine cabinet, and an LCR bridge mounted on the surface of the support plate.

[0008] The test assembly includes a lifting part connected to the side surface of the support plate, a test part connected to the movable end of the lifting part, and a conductive wire connected between the test part and the LCR bridge.

[0009] The feeding assembly includes a base connected to the upper surface of the sorting machine cabinet, a feeding section installed on the inner wall of the base; and,

[0010] The feeding assembly includes a third telescopic rod that runs through the side surface of the support plate, an arc-shaped frame connected to the movable end of the third telescopic rod and located directly below the test section, a pushing section installed inside the base, a first guide groove opened on one side of the upper surface of the base and inclined, and a second guide groove opened on the other side of the upper surface of the base and inclined.

[0011] As a preferred embodiment of the inductor testing and sorting machine of this utility model, the lifting unit includes a bracket connected to the side surface of the support plate and a first telescopic rod connected to the bottom side of the end of the bracket and connected to the testing unit.

[0012] As a preferred embodiment of the inductor testing and sorting machine of this utility model, the lifting unit further includes a guide sleeve connected to the side surface of the testing unit and a slide rail connected to the side surface of the support and adapted to the guide sleeve, so that the testing unit can move axially on the surface of the slide rail.

[0013] As a preferred embodiment of the inductor testing and sorting machine of this utility model, the testing unit includes a test base connected to the movable end of the first telescopic rod and a metal contact sleeve inserted into the bottom side of the test base and connected to the end of the conductive wire.

[0014] As a preferred embodiment of the inductor testing and sorting machine of this utility model, the feeding part includes a feeding seat disposed on the inner wall of the base, two material grooves opened on the surface of the feeding seat, limiting strips respectively connected to the inner walls of the two material grooves, and a second telescopic rod installed on the side surface of the base and whose movable end is connected to the side surface of the feeding seat.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention firstly allows for the loading of inductors through a feeding section. Then, the inductor is tested using a testing assembly. After testing, a fourth telescopic rod drives a pusher plate upwards, pushing the inductor out of the feed trough. If the inductor passes the test, a third telescopic rod extends and pushes the inductor down the surface of the second guide trough via an arc-shaped frame. If the inductor fails, the third telescopic rod retracts and pulls the inductor down the first guide trough via the arc-shaped frame, thus achieving sorting. When the second telescopic rod extends, it pushes the feeding seat laterally to the far end. When the feeding seat moves another inductor to directly below the testing section, the second telescopic rod stops. At this point, the inductor is tested by the testing section. Simultaneously, a new inductor is placed in the first tested trough. Then, the second telescopic rod retracts, resetting the feeding seat, and the testing continues. This process repeats continuously, improving the testing efficiency of the inductors. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0028] This utility model relates to an inductor testing and sorting machine, such as... Figures 1-6 As shown, it includes:

[0029] The sorting machine assembly 100 includes a sorting machine cabinet 101 located at the bottom, a support plate 102 connected to the upper surface of the sorting machine cabinet 101, and an LCR bridge 103 mounted on the surface of the support plate 102.

[0030] The feeding assembly 300 includes a base 301 connected to the upper surface of the sorting machine cabinet 101 and a feeding part 302 installed on the inner wall of the base 301.

[0031] The loading section 302 includes a loading seat 302a located on the inner wall of the base 301, two material grooves 302b formed on the surface of the loading seat 302a, limiting strips 302c connected to the inner walls of the two material grooves 302b respectively, and a second telescopic rod 302d installed on the side surface of the base 301 and whose movable end is connected to the side surface of the loading seat 302a. The inner wall shape formed by the material grooves 302b and the limiting strips 302c is consistent with the size of the inductor to be tested. The inductor to be tested is placed in the material groove 302b connected to the limiting strips 302c. The limiting strips 302c fix the inductor in a fixed direction, so that the inductor pins correspond to the positions of the metal contact sleeve 202b of the test seat 202a. This allows the test seat 202a to easily connect the metal contact sleeve 202b to the inductor pin surface when it moves downwards.

[0032] Furthermore, the loading unit 302 also includes a guide rail 302e connected to the inner wall of the base 301 and a guide groove 302f formed on the side surface of the loading seat 302a and adapted to the guide rail 302e. When the loading seat 302a is subjected to a force, it can drive the guide groove 302f to slide on the surface of the guide rail 302e, which can limit the movement direction of the loading seat 302a and thus maintain the stability of the sliding of the loading seat 302a.

[0033] In use, the inductor is first placed in the material slot 302b connected to the limit bar 302c directly below the test section 202. Then, the inductor is tested by the test assembly 200. At the same time, another inductor is placed in another material slot 302b. Then, the second telescopic rod 302d can be operated. When the second telescopic rod 302d extends, it can push the loading seat 302a to slide laterally to the far end on the inner wall of the base 301. When the loading seat 302a moves the other inductor to directly below the test section 202, the second telescopic rod 302d stops running. At this time, the inductor can be tested by the test section 202. At the same time, a new inductor is placed in the first material slot 302b that has been tested. Then, the second telescopic rod 302d is controlled to retract, driving the loading seat 302a to reset. Then, the test is continued by the test section 202. This process can be repeated to achieve continuous and uninterrupted testing of the inductor. Example 2

[0034] like Figures 1-2 The second embodiment of the present invention is shown, which differs from the first embodiment described above only in that: the test component 200 includes a lifting part 201 connected to the side surface of the support plate 102, a test part 202 connected to the movable end of the lifting part 201, and a conductive line 203 connected between the test part 202 and the LCR bridge 103.

[0035] The lifting unit 201 includes a bracket 201a connected to the side surface of the support plate 102, and a first telescopic rod 201b connected to the bottom side of the end of the bracket 201a and connected to the test unit 202. When the first telescopic rod 201b is running, it can drive the test unit 202 to move axially, thereby adjusting the position of the test unit 202 and facilitating the connection between the test unit 202 and the pins of the inductor for convenient testing.

[0036] Furthermore, the lifting unit 201 also includes a guide sleeve 201c connected to the side surface of the testing unit 202 and a slide rail 201d connected to the side surface of the bracket 201a and adapted to the guide sleeve 201c, so that the testing unit 202 can move axially on the surface of the slide rail 201d. When the testing unit 202 is subjected to a force, it can drive the guide sleeve 201c to slide on the surface of the slide rail 201d, which can limit the direction of movement of the testing unit 202 and maintain the stability of the movement of the testing unit 202.

[0037] Furthermore, the testing unit 202 includes a test base 202a connected to the movable end of the first telescopic rod 201b, and a metal contact sleeve 202b inserted into the bottom side of the test base 202a and connected to the end of the conductive wire 203. The metal contact sleeve 202b is electrically connected to the LCR bridge 103 through the conductive wire 203, so that the inductance L, capacitance C, and resistance R parameters of the inductor can be tested after the LCR bridge 103 is energized.

[0038] When in use, the first telescopic rod 201b can drive the test seat 202a to move downwards. When the test seat 202a drives the metal contact sleeve 202b to move downwards and fits on the surface of the inductor pins, a circuit is established between the metal contact sleeve 202b and the inductor pins. Then, the inductor can be tested by the LCR bridge 103. Example 3

[0039] like Figures 1-6 The third embodiment of the present invention is shown, which differs from the second embodiment described above only in that: the feeding assembly 400 includes a third telescopic rod 401 that is installed through the side surface of the support plate 102, an arc-shaped frame 402 connected to the movable end of the third telescopic rod 401 and located directly below the test section 202, a pushing section 403 installed inside the base 301, a first guide groove 404 that is opened on one side of the upper surface of the base 301 and is inclined, and a second guide groove 405 that is opened on the other side of the upper surface of the base 301 and is inclined.

[0040] The pusher section 403 includes a fourth telescopic rod 403a installed on the inner wall of the base 301 and located directly below the arc-shaped frame 402, and a pusher plate 403b connected to the movable end of the fourth telescopic rod 403a. When the fourth telescopic rod 403a extends, it can drive the pusher plate 403b to move upward. When the pusher plate 403b moves upward, it can squeeze the inductor on the inner wall of the material trough 302b upward until the inductor moves to the outside of the material trough 302b.

[0041] In use, after the inductor test is completed, the fourth telescopic rod 403a is activated. When the fourth telescopic rod 403a is running, it drives the pusher plate 403b to move upward. When the pusher plate 403b moves upward, it squeezes the tested inductor upward until it moves to the outside of the material trough 302b. At this time, the inductor moves to the inner wall of the arc frame 402. When the inductor test result is qualified, the third telescopic rod 401 is controlled to extend. When the third telescopic rod 401 extends, it can push the inductor to move laterally towards the second guide trough 405 through the arc frame 402. When the inductor moves to the surface of the second guide trough 405, it slides down its slope. When the inductor test result is not unqualified, the third telescopic rod 401 is controlled to retract. When the third telescopic rod 401 retracts, it can push the inductor to move laterally towards the first guide trough 404 through the arc frame 402. When the inductor moves to the surface of the first guide trough 404, it slides down its slope. In this way, the inductor can be sorted.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
