Description

Technical Field

[0001] This utility model relates to the field of electronic components technology, and in particular to a rapid testing device for inductor products. Background Technology

[0002] Inductors, as a crucial component in power modules, are increasingly widely used, and their size is becoming smaller and smaller. Inductors are formed by winding copper wire around a magnetic core. Due to their tiny size, with a maximum three-dimensional dimension of only 2-3 mm and a small copper wire diameter, issues such as wire breakage, improper winding, or misalignment of the two pins may occur during winding. Therefore, inspection is necessary after production. Current technology typically relies on manual inspection, but this significantly impacts efficiency during mass production. Furthermore, the small size of inductors makes prolonged manual inspection prone to visual fatigue, leading to missed or false positives. Therefore, how to quickly inspect inductors is a problem that those skilled in the art need to consider.

[0003] To address the problems existing in the current technology. Utility Model Content

[0029] The present invention will be further described in detail below with reference to specific embodiments:

[0030] like Figures 1-3 As shown, this utility model is applied to the testing of miniature inductor products. In this embodiment, the miniature inductor product consists of a magnetic core and a coil. The magnetic core includes a base plate and a boss. Copper wire is wound around the boss, and two leads are folded towards the side of the base plate away from the boss and bent to fit against the base plate. Therefore, both the front (the side where the coil is located) and the back (the side where the leads are located) need to be tested. In this utility model, the inductor product is automatically fed using a vibratory feeder, and the inductors are oriented in the same direction during feeding. Then, the front of the inductor is visually inspected at the first testing station. After passing through a flipping station, the inductor product is flipped so that the back can be inspected when it passes through the second testing station. Specifically, a rapid testing device for inductor products includes:

[0031] The feeding assembly 1 includes a feeding hopper 11, the discharge end of which is connected to a first guide trough 12; a first direct vibration device 13 is connected to the first guide trough 12. In this embodiment, after the inductor product is formed, it is conveyed to the feeding hopper 11 and then enters the first guide trough 12; subsequently, driven by the first direct vibration device 13, it enters the vibratory feeder from the first guide trough 12.

[0032] The transmission assembly 2 includes a vibratory feeder 21 connected to the discharge end of the first feed chute 12, a transmission track 22 connected to the vibratory feeder 21, and a second linear vibration device 23 connected to the transmission track 22. A detection assembly 3 is provided on the side of the transmission assembly 2.

[0033] The transmission track 22 is provided with a first detection station 22a, a flipping station 22b, and a second detection station 22c in sequence along the transmission direction of the inductor product.

[0034] The cross-section of the transmission track 22 at the first testing station 22a is a V-shaped groove formed by the first side plate 24 and the second side plate 25. When the inductor product is transmitted by the vibratory feeder 21, it moves with its back against the first side plate 24. At the first testing station 22a, the first side plate 24 is provided with a first air hole 241, which is covered when the inductor product passes through the first testing station 22a. The second side plate 25 is provided with a first notch 251, and a first collection box 252 is provided below the first notch 251. In this embodiment, the first testing device 31 is located to the side of the first testing station 22a. The position and angle of the first camera 311 on the first bracket 312 can be adjusted according to actual needs so that the first camera 311 can accurately focus on the first testing station 22a. When the inductor product passes through the first testing station 22a, the back of the product abuts against the first side plate 24, and the front is at the first notch 251. The first camera 311 captures an image of the front of the product and performs testing. Products that pass inspection continue to be conveyed on the conveyor track 22; products that fail inspection are blown with air through the first air hole 241, causing the products to fall into the first collection box 252 through the first notch 251.

[0035] The cross-section of the transmission track 22 where the flipping station 22b is located is a concave groove, and the straight line of the opening direction of the concave groove formed by the inlet end cross-section of the transmission track 22 where the flipping station 22b is located forms a 90° angle with the straight line of the opening direction of the concave groove formed by the outlet end cross-section. In this embodiment, the section of the transmission track 22 where the flipping station 22b is located is a smooth curved twist. When the inductor product passes through, it changes from a state of back contact with the sidewall to a state of front contact with the sidewall, so that when the inductor product enters the transmission track 22 where the second detection station 22c is located, it moves from front contact with the sidewall.

[0036] The cross-section of the transmission track 22 at the second testing station 22c is a V-shaped groove formed by the third side plate 26 and the fourth side plate 27. During inductor transmission, the front moves against the third side plate 26. At the second testing station 22c, a second vent 261 is provided on the third side plate 26, which can be covered when the inductor product passes by; a second notch 271 is provided on the fourth side plate 27, and a second collection box 272 is provided below the second notch 271.

[0037] In this embodiment, the second detection device 32 is positioned to the side of the second detection station 22c. The position and angle of the second camera 321 on the second bracket 322 can be adjusted according to actual needs so that the second camera 321 is focused on the second detection station 22c. When the inductor product passes through the second detection station 22c, the front of the product abuts against the third side plate 26, and the back is close to the second notch 271. At this time, the image of the back of the product can be captured by the second camera 321 and detected. After detection, if the product is qualified, it continues to be conveyed on the transmission track 22; if the product is unqualified, air is blown through the second air hole 261, causing the product to fall along the second notch 271 into the second collection box 272.

[0038] In this embodiment, the product that has passed two tests is dropped from the outlet end of the conveyor track 22 into the second guide trough 28 located directly below it; and under the drive of the third vertical vibration device 281, it is discharged along the discharge pipe 282 at the end of the second guide trough 28 to the next process or collected.

[0039] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and therefore, all changes falling within the meaning and scope of the equivalents of the claims are intended to be included within this utility model.
