[0025] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the disclosure of this invention and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of this invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0026] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0027] Reference Figures 1 to 3 As shown, this embodiment provides a bending jig for thin film inductor terminals (hereinafter referred to as a bending jig) for bending the terminals of the thin film inductor during the manufacturing process of the inductor product.

[0028] The bending jig of this embodiment includes a first mold 1 and a second mold 2 arranged in an upper and lower manner. The first mold 1 includes a first alignment unit 11 and an ejector assembly 12. The ejector assembly 12 includes a retractable ejector 123. Figure 7 and Figure 8The second mold 2 shown includes a second alignment unit and a placement groove 22 for accommodating the thin film inductor. The bottom of the placement groove 22 is provided with a clearance groove 23 for cooperating with the bending of the terminal of the thin film inductor. When the first mold 1 and the second mold 2 are covered, the first alignment unit 11 and the second alignment unit cooperate to align the ejector pin 123 of the ejector pin assembly 12 with the terminal of the thin film inductor on the placement groove 22, and when the ejector pin assembly 12 is pressed down, the ejector pin 123 of the ejector pin assembly 12 applies downward pressure on the terminal of the thin film inductor so that the terminal of the thin film inductor is bent toward the clearance groove 23.

[0029] In this embodiment, the thin film inductor has a plurality of inductor monomers, that is, the thin film inductor is a large plate used in the manufacturing process of the inductor product. The plurality of inductor monomers are arranged in an array, and each inductor monomer is provided with a terminal. The number of ejector pins 123 is set to be multiple, and each corresponds to the terminal of each inductor monomer. The number of recesses 23 is set to be multiple, and they are distributed at intervals, such as Figure 8 The top wall 231 of the recess 23 is used to abut against the connection between the inductor unit and the terminal to provide support.

[0030] like Figure 4 and Figure 5 As shown, the ejector assembly 12 includes a pressing plate 121, an ejector plate 122, and an ejector 123 fixed on the ejector plate 122. Figure 6 The shown pressing plate 121 is provided with an ejector hole 124 for cooperating with the extension and contraction of the ejector 123. The ejector plate 122 is assembled to the pressing plate 121 through an elastic connecting piece 13, and the ejector 123 is lifted and lowered through the ejector hole 124. Specifically, the elastic connecting piece 13 is a spring.

[0031] When it is necessary to bend the terminals of the thin film inductor, first fix the ejector plate 122 of the first mold 1 on the downward pressing movable template of the bending machine, and the second mold 2 is fixed on the base of the bending machine and remains stationary, and the ejector assembly 12 is driven by the downward pressing movable template to gradually approach the second mold 2. Then, a downward external force or pressure is applied to the ejector plate 122 by the downward pressing movable template to overcome the elastic force limitation of the spring, and the top wall 231 of the yield groove 23 and the pressure plate 121 cooperate to tighten the connection between the inductor monomer and the terminal located between the two, which can also ensure that the thin film inductor will not accidentally slide on the surface of the bending jig, thereby avoiding damage to the thin film inductor, and synchronously drive the ejector 123 to extend downward in the ejector through hole 124 to achieve pressing or bending the terminal. Of course, the thin film inductor can also be fixed by vacuum adsorption to prevent the thin film inductor from deforming during bending and affecting the bending of the terminal.

[0032] After the terminals of the thin film inductor are bent, the template is lifted and pressed down to remove the external force on the ejector plate 122. The ejector plate 122 relies on the elastic force of the spring to drive the ejector 123 to retract upward into the ejector hole 124. The first mold 1 and the second mold 2 are separated synchronously to facilitate the removal of the thin film inductor with bent terminals.

[0033] More specifically, Figure 1 and Figure 2 The first alignment unit 11 shown includes an alignment guide column 111, the middle part of which is passed through and fixed on the pressure plate 121, and the ejector plate 122 is provided with a guide slot 125, and the alignment guide column 111 can be slidably inserted into the guide slot 125 toward the upper end of the ejector plate 122.

[0034] like Figure 7 The second alignment unit shown includes an alignment groove 21 that cooperates with the alignment guide column 111 for alignment. When the first mold 1 and the second mold 2 are covered, the alignment guide column 111 is slidably inserted into the alignment groove 21 toward the lower end of the second mold 2, so that each ejector pin 123 is aligned with the corresponding terminal of the thin film inductor on the placement groove 22.

[0035] The bending jig of this embodiment can simultaneously bend the terminals of all inductor units on the entire large board, thereby significantly improving the efficiency of the terminal bending operation of the thin film inductor.

[0036] When the first mold 1 and the second mold 2 are covered, the first alignment unit 11 and the second alignment unit cooperate to ensure that the ejector pins 123 of the ejector pin assembly 12 are aligned with the terminals of the thin film inductor on the placement groove 22. When the ejector pin assembly 12 is pressed down, the ejector pins 123 of the ejector pin assembly 12 apply downward pressure to the terminals of the thin film inductor, so that the terminals of the thin film inductor are bent downward toward the yield groove 23. This can replace manual bending of the terminals of the thin film inductor to ensure the efficiency and stability of the bending operation.

[0037] Furthermore, in this embodiment, the retractable ejector pin 123 replaces the existing simple bending tool to avoid performing the terminal bending operation directly on the surface of the thin film inductor, thereby effectively preventing damage to the inductor product.

[0038] More preferably, Figure 1 、 Figure 2 and Figure 7 As shown, the outer peripheral surface of the ejector plate 122 is equipped with a coarse adjustment positioning block 14, and the outer peripheral surface of the second mold 2 is provided with a coarse adjustment groove 24 for cooperating with the coarse adjustment positioning block 14 for positioning. The coarse adjustment positioning block 14 can be detachably inserted into the coarse adjustment groove 24 to ensure that the first mold 1 and the second mold 2 are coarsely aligned before the first alignment unit 11 and the second alignment unit are aligned, thereby ensuring that the first alignment unit 11 and the second alignment unit are smoothly aligned with each other in the next step.

[0039] Of course, in other embodiments, the positions of the coarse adjustment positioning block 14 and the coarse adjustment groove 24 can be replaced, so as to achieve coarse adjustment alignment between the first mold 1 and the second mold 2 .

[0040] Further preferably, the width of the clearance groove 23 parallel to the length direction of the unbent terminal is not less than the length of the terminal itself, so as to ensure that no mechanical interference occurs when the terminal is bent in the clearance groove 23.

[0041] In another preferred embodiment, Figure 1 and Figure 7 As shown, the outer shape of the pressing plate 121 is indented into the outer shape of the ejector plate 122. The second mold 2 is provided with a limit block 25 surrounding the pressing plate 121. When the first mold 1 and the second mold 2 are covered, the limit block 25 abuts the ejector plate 122 to play a foolproof role, that is, to prevent the pressing plate 121 from pressing against the thin film inductor in the placement groove 22, thereby preventing excessive pressure and damaging the inductor product.

[0042] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the form and details of the present invention without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these changes are within the scope of protection of the present invention.
