Description

Technical Field

[0001] The utility model relates to the technical field related to inductors, and in particular to an inductor through-hole reflow device. Background Art

[0002] Common-mode inductors, also called common-mode chokes, are commonly used in switching power supplies to filter common-mode electromagnetic interference signals. In TV board design, common-mode inductors act as EMI filters, suppressing the outward radiation of electromagnetic waves generated by high-speed signal lines.

[0003] Commonly used inductors are generally manually plug-in operations. As the industry's labor costs are getting higher and higher, in order to reduce labor costs, commonly used inductors are changed to surface-mount inductors. However, the cost of surface-mount inductors is several times that of commonly used plug-in costs, and PCBA has no competitive advantage. Utility Model Content

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The following describes the specific embodiments of the present invention in conjunction with the accompanying drawings.

[0021] like Figure 1-4 As shown, an inductor through-hole reflow device includes a base 1, a magnetic core 2 is assembled on the top of the base 1, and coils 3 are wound around both ends of the magnetic core 2. The inductor is composed of the base 1, the magnetic core 2 and the coil 3.

[0022] A fiberglass board 4 is placed on the top of the coil 3. In actual use, the size of the fiberglass board 4 is determined by the size of the suction nozzle. The operation of sucking the fiberglass board 4 by the suction nozzle to move the inductor solves the problem of manual plug-in operation and reduces labor costs. It is cheaper than patch materials and reduces processing costs.

[0023] The fixing plate 5 is connected with the fixing plate 7 at the bottom of the fixing plate 5, and the fixing plate 5 is connected with the fixing plate 7 at the bottom of the fixing plate 5. When the cam 8 is in contact with the magnetic core 2, the cam 8 is moved upwards to move the inductor 4. The top of the connecting plate 7 is equipped with a push plate 9, and the top of the push plate 9 is in sliding contact with the bottom of the glass fiber board 4, and the side away from the push plate 9 is located on the outside of the glass fiber board 4. The push plate 9 serves to facilitate the staff to move the connecting plate 7. When in use, by pressing the connecting plate 7, the limit block 8 is driven to slide and disengage from the magnetic core 2, thereby realizing the removal of the glass fiber board 4 from the inductor. A slider 10 is installed on the top of the connecting plate 7. The shape of the slider 10 is T-shaped, and the bottom of the glass fiber board 4 is provided with a slide groove adapted to the size of the slider 10. The slider 10 and the slide groove increase the friction resistance between the connecting plate 7 and the glass fiber board 4, so that the connecting plate 7 can only slide in a straight line at the bottom of the glass fiber board 4, avoiding the glass fiber board 4 from being out of contact with the connecting plate 7.

[0024] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
