Abstract
Description
Technical Field
[0001] The utility model relates to the field of transformer positioning and installation, in particular to a positioning mechanism suitable for the transformer. Background Art
[0002] The preparation process of the transformer includes but is not limited to various processes such as winding, stripping, flying wire twisting, and soldering. In the above processes, the transformer uses pneumatic fingers to implement position changes on the transformer. In short, the transformer performs the processes of winding, stripping, and flying wire on the pneumatic fingers.
[0003] In fact, this simple positioning method has some big problems, such as the lack of the function of protecting key positions. When soldering the twisted flying wires, the tin beads or tin slag will stick to the transformer, which may burn the frame, tape, and wire package. Utility Model Content
[0004] In order to solve the above problems, the utility model provides a positioning mechanism suitable for a transformer, which comprehensively covers the non-soldering parts of the transformer to ensure that the solder beads / tin slag cannot damage the parts of the transformer such as the frame.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] Furthermore, a jig is provided in the assembly space, and the transformer is installed in the jig to ensure that the transformer does not shake.
[0008] Furthermore, a pair of side surfaces of the fixture are limit plates, and the limit plates are located between two raised structures of the transformer. The raised structures are supported by the limit plates to position the transformer.
[0009] Furthermore, auxiliary parts are arranged at two extreme positions along the length direction of the limiting plate. The auxiliary parts serve as another pair of side surfaces of the fixture and are connected to the limiting plate to enclose the transformer.
[0010] Furthermore, the limiting plates are connected in a detachable manner, and by removing any limiting plate, the assembly space is opened for taking out or storing the transformer.
[0011] Furthermore, a limit plate is slidably connected to the auxiliary component, eliminating the need to use other auxiliary structures to achieve the connection relationship between them.
[0012] Furthermore, the bottom of the jig is a jig base, which has a limiting structure located between two limiting plates. After the two limiting plates are connected, the jig is maintained in a posture with a spacing due to the existence of the limiting structure.

[0029] The following detailed description of example embodiments is provided with reference to the accompanying drawings. The same reference numerals in different drawings represent the same or similar elements. Moreover, the drawings are not necessarily drawn to scale. The following detailed description does not limit the present invention. The scope of protection of the present invention is defined by the appended claims.
[0030] In the specification, references to "one embodiment," "an embodiment," or "some embodiments" mean that a particular feature, structure, or element described with reference to the embodiment is included in at least one embodiment of the subject matter being described. Thus, the phrases "in one embodiment," "in an embodiment," or "in some embodiments" in the specification do not necessarily refer to the same embodiment or embodiments. The particular features, structures, or elements may be further combined in any embodiment in a suitable manner.
[0031] Figure 1 The transformer has two conductors 1a and a frame 1b that is approximately annular in structure. Figure 2 It is the internal structure diagram of the assembly space. Figure 2 It can be seen that a plurality of transformers 1 are installed inside the fixture 2. The posture of the transformer 1 is maintained with two conductors 1a respectively located on the edges of the two ends of the frame 1b. The conductors 1a are located on the same horizontal plane and extend in opposite directions.
[0032] In addition, two ends of the transformer 1 have a group of protrusion structures 1c opposite to each other.
[0033] like Figure 5 As shown, the positioning mechanism includes a jig 2, a jig base 3, and a jig cover 4. The jig base 3 includes a base bottom plate 3a and a support structure 3b arranged on the base bottom plate 3a. The support structure 3b is a surrounding structure, forming an assembly space surrounding the jig 2. The jig 2 is placed on the jig base 3, and the jig cover 4 covers the jig base 3 to wrap the jig 2.
[0034] like Figure 4 As shown, a lead hole 3b' is provided on the upper edge of the support structure 3b, and the wire 1a passes through the lead hole 3b'; when the wire 1a is soldered, the generated tin beads and tin slag are blocked outside by the fixture mother seat 3 and the fixture cover plate 4.
[0035] Under the action of the fixture 2, the wire 1a on the transformer 1 and the lead hole 3b' are in a relative state and in a horizontal state.
[0036] like Figure 1-12 As shown, the jig 2 includes a limit plate, an auxiliary part 2c, a jig base 2d, and a jig top plate 2e. In particular, the limit plate and the auxiliary part 2c are arranged in pairs, and the limit plate and the auxiliary part 2c are alternately arranged above and along the four sides of the jig base 2d. The limit plate is divided into a first limit plate 2a and a second limit plate 2b. The first limit plate 2a and the second limit plate 2b are connected to each other by screws in an interval manner, and the first limit plate 2a and the auxiliary part 2c are slidably connected. A connecting part 2f is provided on the jig base 2d, and the connecting part 2f extends toward the jig top plate 2e and is fixedly connected to the jig top plate 2e. The transformer 1 is constrained between the first limit plate 2a and the second limit plate 2b.
[0037] When taking out or assembling the transformer 1 , it is only necessary to disassemble the second limiting plate 2 b and remove the screws. The disassembly method of the fixture 2 is relatively simple and less complicated.
[0038] In fact, the transformer 1 is positioned in the jig 2 by the limiting plate. Direction X is the axial direction of the transformer 1, and the raised structure 1c extends outward along the axial direction. Therefore, when the transformer 1 is in the jig 2, the raised structure 1c and the edge of the limiting plate are relative to each other. In addition, the width of the limiting plate is smaller than the spacing between the raised structures 1c. During assembly, the limiting plate is inserted between the raised structures 1c. After the limiting plate is fixed to the jig 2 body, the upper edge of the limiting plate supports the raised structure 1c.
[0039] In some embodiments, a slide groove 2c' is provided on the inner side of the auxiliary part 2c, and sliders 2a' are respectively provided on both ends of the first limiting plate 2a. The slider 2a' is slidably connected to the slide groove 2c'. A single sliding connection method can quickly form a connection relationship with the auxiliary part 2c. The screw fixing method of the second limiting plate 2b can ensure that the distance between the second limiting plate 2b and the first limiting plate 2a is compact for the transformer 1.
[0040] In addition, compared with other connection methods, the sliding connection method eliminates the need for other auxiliary structures.
[0041] A limiting structure 2g is also provided on the fixture base 2d between the first limiting plate 2a and the second limiting plate 2b. The limiting structure 2g is a limiting block, which prevents the first limiting plate 2a from detaching from both ends of the slide groove 2c'.
[0042] The bottom of the fixture base 2d is provided with a plurality of pick-up and delivery holes, which are used in conjunction with an external moving mechanism. The output end of the moving mechanism can be inserted into the pick-up and delivery holes. When moving, the entire fixture base 2d can be dragged to transport the fixture 2.
[0043] The moving mechanism is a prior art, and its structure will not be further described.
[0044] A pair of wire plates 3c are also provided on the base plate 3a of the female seat, which are respectively located outside the first limiting plate 2a and the second limiting plate 2b. A groove 3d is provided at the upper end of the wire plate 3c. The wire 1a outside the lead hole 3b' is inserted into the groove 3d. The wire 1a is in a horizontal state through the groove 3d. This is to allow the laser to fully irradiate the outer sheath of the wire 1a during the subsequent laser stripping, so as to strip the wire 1a.
[0045] A pressing plate 4a extending to the top of the wire plate 3c is provided on the upper surface of the jig cover 4. The pressing plate 4a rests on the upper edge of the wire plate 3c to constrain the wire 1a in the groove 3d.
[0046] In the embodiment, there are a plurality of connecting portions 2 f , which are arranged in an array, and the transformers 1 are separated by the connecting portions 2 f .
[0047] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
