Description

Technical Field

[0001] This application relates to the field of inductor production equipment, specifically to a micro inductor online visual inspection fixing device. Background Technology

[0002] Miniature inductors, also known as chip inductors or integrated circuit inductors, are key miniaturized electronic components used to store and convert electrical energy. They operate based on the law of electromagnetic induction, storing electrical energy in the form of a magnetic field and releasing it when needed, thus ensuring stable circuit operation.

[0003] Chinese patent document CN218470562U discloses a multi-angle visual inspection device for surface mount inductors, specifically disclosing a support component and a first adjustment component and a second adjustment component disposed on the surface of the support component. A first fixing member and a detection component are also disposed above the support component. The support component includes a support platform and a first and a second sliding groove formed on the surface of the support platform. The first adjustment component includes a first support frame disposed on the surface of the support platform and a first fixing groove formed on the surface of the first support frame. This multi-angle visual inspection device for surface mount inductors, by setting multiple vision modules, can simultaneously inspect surface mount inductors from multiple different orientations and angles, thereby performing branch comparisons from multiple angles and reducing the error of the inspection results.

[0004] However, the aforementioned patent requires removing the inductor after testing and then inserting a new inductor during the testing process, which reduces testing efficiency. Moreover, the position of the inductor may change during placement, meaning the inductor may move away from the testing component or multiple inductors may stack, affecting testing accuracy.

[0027] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] like Figure 1-6 As shown, a miniature inductor online visual inspection and fixing device includes several housings 1 sequentially placed on a conveyor belt 2. A support 20 is provided on the outer side of the conveyor belt 2, and a visual inspection mechanism 3 is mounted on the support 20. The visual inspection mechanism 3 is located above the conveyor belt 2. Under the conveyor belt 2, the housings 1 can pass through the visual inspection mechanism 3 sequentially. The visual inspection mechanism 3 generally consists of a high-definition camera, an image processor, etc. The high-definition camera can quickly capture images of the inductors, and the image processor analyzes and processes the images to determine whether the inductors are qualified. Commonly available industrial high-definition cameras and professional image analysis software can be used in this device.

[0029] The housing 1 has a vertically penetrating cavity 11 in its middle. The cavity 11 has an upper partition 4 at the top and a lower partition 5 at the bottom. Both partitions 4 and 5 are perforated plates. An air pump 6 is located between them. The air pump 6's inlet pipe 61 is inside the cavity 11, and its outlet pipe 62 is outside. The upper partition 4 is used to hold inductors. Thus, the conveyor belt 2 moves the housing 1, allowing the inductors to pass sequentially through the vision inspection mechanism 3 for continuous online inspection, improving inspection efficiency and accuracy, and avoiding the inefficiency of intermittent inspection. Furthermore, the air pump 6 draws in air through the inlet pipe 61 and exhausts air through the outlet pipe 62, extracting gas from the cavity 11 and creating a negative pressure within it. This allows the inductors to be adsorbed and fixed on the upper partition 4, preventing displacement and ensuring the accuracy of the inspection results. A small centrifugal pump is typically used, which is compact and has strong suction.

[0030] The conveyor belt 2 is typically made of rubber, providing friction to stably move the housing 1. Simultaneously, the bottom of the housing 1 has end-to-end mounting grooves 14, within which a sealing ring 15 is installed. The sealing ring 15 is generally made of rubber, offering good elasticity and sealing performance; alternatively, it can be made of silicone, which provides better aging resistance. When the housing 1 is placed on the conveyor belt 2, the sealing ring 15 adheres closely to the belt, effectively preventing air leakage from the bottom of the housing 1 when the air pump 6 draws in air. This enhances the adhesion of the housing 1 to the conveyor belt 2, ensuring smooth movement of the housing 1 and its internal inductor as the conveyor belt 2 transports the housing 1.

[0031] Both the upper partition 4 and the lower partition 5 are perforated plates. The size of the mesh in the upper partition 4 is designed according to the size of the inductor, ensuring that the inner diameter of the mesh in the upper partition 4 is smaller than the outer diameter of the inductor and that the inductor does not fall down. The upper partition 4 is placed on top of the upper mounting ring 12 on the inner wall of the accommodating cavity 11, and the two are magnetically attracted together. This facilitates the removal and replacement of the upper partition 4 while ensuring a tight connection. The upper mounting ring 12 is generally made of a magnetic metal material, such as an iron-nickel alloy, or a magnet can be embedded in a regular metal ring to ensure a reliable attraction between the upper mounting ring 12 and the upper partition 4. The lower partition 5 is connected to the lower mounting ring 13 by bolts 50 to ensure the stability of the connection. The distance between the top of the upper partition 4 and the top of the housing 1 is less than the distance between the bottom of the lower partition 5 and the bottom of the housing 1. This design allows sufficient space above the upper partition 4 for placing the inductor, while the bottom of the lower partition 5 is closer to the conveyor belt 2, thereby improving the attraction effect between the housing 1 and the conveyor belt 2. Furthermore, the top of the accommodating cavity 11 is provided with a guide ramp 16, which facilitates the inductor to slide down the ramp onto the upper partition 4.

[0032] A pair of support beams 17 are provided within the accommodating cavity 11, located between the upper mounting ring 12 and the lower mounting ring 13. The support beams 17 are generally made of metal square tubing, which has high strength, or they can be made of I-beams, capable of withstanding greater pressure. The support beams 17 are used to support the air pump 6 and to install other components. Each end of the air pump 6 has an air outlet pipe 62. The air outlet pipe 62 passes through the support beams 17 and the housing 1, extending to the outside of the housing 1. The extension direction of the air outlet pipe 62 is perpendicular to the conveying direction of the conveyor belt 2. This arrangement avoids interference between the air outlet pipe 62 and the operation of the conveyor belt 2, or inductive crosstalk caused by airflow between adjacent housings 1. At least one air inlet pipe 61 is provided at the top and bottom of the air pump 6. The air inlet pipe 61 at the top of the air pump 6 points towards the upper partition 4, and the air inlet pipe 61 at the bottom of the air pump 6 points towards the lower partition 5. Simultaneous intake from both top and bottom enhances the adsorption effect.

[0033] A pair of mounting brackets 18 are provided between a pair of support beams 17. A vibratory motor 7 is mounted on each mounting bracket 18. The vibratory motor 7 can be an eccentric block vibratory motor 7, which has a large excitation force and is easy to adjust, or it can be an electromagnetic vibratory motor 7, which operates smoothly and with low noise. The vibratory motor 7 is used to deliver excitation force to the housing 1, ensuring that the inductance is evenly distributed on the upper partition 4 and preventing the inductance from stacking. An internal battery can be used to power the air pump 6 and the vibratory motor 7, ensuring that the air pump 6 and the vibratory motor 7 inside the housing 1 can operate reliably when the housing 1 is conveyed by the conveyor belt 2.

[0034] The implementation principle of this embodiment is as follows: Continuous online detection of inductance is achieved using the conveyor belt 2, greatly improving detection efficiency. The air pump 6, in conjunction with the upper partition 4 and lower partition 5, adsorbs and fixes the inductor, preventing positional changes during detection and improving detection accuracy. The sealing ring 15 enhances the adsorption effect of the housing 1 on the conveyor belt 2, the guide ramp 16 facilitates inductor feeding, and the vibrating motor 7 ensures uniform inductor distribution.

[0035] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
