Description

Technical Field

[0001] The present invention relates to the technical field of inductor manufacturing, and particularly relates to a positioning tool for inductor manufacturing and processing. Background Art

[0002] A wireless charging coil, as a type of inductor, is crucial for precise positioning and smooth feeding during its tin dipping process, which relies on a dedicated positioning tool to achieve.

[0003] Existing wireless charging coil positioning tools often face the need to provide precise positioning for coils of different sizes and complete the tin dipping operation in practical applications. Currently, most positioning molds for wireless charging coils are installed on the positioning tool through fasteners such as bolts. Although this fixing method ensures stability, when it is necessary to replace the mold to adapt to different coil sizes, a series of cumbersome fastener disassembly processes need to be carried out first. This step takes a long time, affects the efficiency of mold replacement, and reduces the usability of the positioning tool. Summary of the Invention

[0004] Embodiments of the present disclosure relate to a positioning tool for inductor manufacturing and processing, which can automatically rotate the limit cam when two positioning slides are docked and lowered in preparation for tin dipping, so as to limit the positions of positioning mold A and positioning mold B, ensuring the stability of positioning mold A and positioning mold B after being put into use. And after the tin dipping is completed, when the two positioning slides rise, the two positioning slides will open relative to each other, facilitating the staff to remove the wireless charging coil that has been tinned. Moreover, the limit cam will also rotate and return to its original state, canceling the positioning of positioning mold A and positioning mold B. In this way, without the intervention of bolt fasteners, the disassembly step before replacing the mold is omitted, facilitating the staff to replace the mold structure and improving the usability of this positioning tool.

[0007] In at least some embodiments, the lowest end of the conversion inclined groove is communicated with the highest end of the guiding vertical groove; pushing cylinders are fixedly installed on the left and right sides of the top of the positioning base.

[0008] In at least some embodiments, the conversion sliding column is in a cylindrical structure; the outer end of the conversion sliding column is also slidably installed in a guiding groove structure jointly formed by the guiding vertical groove and the conversion inclined groove.

[0009] In at least some embodiments, a fitting part is fixedly installed at the outer end of the conversion sliding column; a spring A is jointly fitted between two adjacent fitting parts.

[0015] The present invention provides a positioning tool for the manufacturing and processing of inductors, and has the following beneficial effects: First, this positioning tool can automatically achieve the precise docking of two positioning slide plates before the wireless charging coil descends and contacts the tin dipping furnace, so that the positioning die A and the positioning die B are tightly closed, and the wireless charging coil to be subjected to tin dipping treatment is accurately positioned through the cooperation of the positioning convex block and the positioning cushion block, thereby ensuring the stability of the tin dipping process.

[0016] Second, when the two positioning slide plates are docked and ready to descend for tin dipping, the tool can automatically trigger the rotation mechanism of the limit cam, effectively limiting the positions of the positioning die A and the positioning die B, ensuring their stability during use, and improving the efficiency and safety of the tin dipping operation.

At the same time, the limit cam will automatically rotate and return to its original position, releasing the positioning of the positioning die A and the positioning die B. In this way, the positioning of the mold does not require the intervention of bolt fasteners, saving the cumbersome disassembly steps before replacing the mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Please refer to Figures 1 to 8 : Embodiment 1: The present invention provides a positioning tool for the manufacturing and processing of inductors, comprising: a positioning base 1, on the outer side of which a guiding vertical groove 3 is provided; a conversion inclined groove 4 is also provided on the outer side of the positioning base 1; a feed slide plate 6 is sleeved and slidably mounted on the positioning base 1; an opening and closing guiding groove 7 is provided inside the feed slide plate 6; an opening and closing slide block 8 is slidably mounted inside the opening and closing guiding groove 7; a conversion slide column 9 is fixedly mounted on the outer side of the opening and closing slide block 8; a positioning slide plate 11 is fixedly mounted on the inner side of the opening and closing slide block 8; a positioning card slot 12 is provided inside the positioning slide plate 11; a positioning die A 13 is slidably mounted inside the positioning card slot 12 at the front; a positioning cushion block 14 is fixedly mounted on the rear side of the positioning die A 13; a positioning die B 15 is slidably mounted inside the positioning card slot 12 at the rear; a positioning convex block 16 is fixedly mounted at the center of the front side of the positioning die B 15; a connecting bracket 17 with an inverted U-shaped structure is fixedly mounted on the tops of the two feed slide plates 6; fitting grooves 19 are provided on the left and right sides of the positioning slide plate 11; a pressure-receiving slide plate 20 is slidably mounted inside the fitting grooves 19; a conversion convex column 23 is fixedly mounted on the inner side of the pressure-receiving slide plate 20; limiting rotating shafts 24 are rotatably mounted at the left and right ends on the outer side of the positioning slide plate 11; a conversion rotating shaft 25 is fixedly mounted at the bottom end of the limiting rotating shaft 24; a conversion screw groove 26 is provided on the circumferential outer wall of the conversion rotating shaft 25; a switching rotating shaft 28 is rotatably mounted at the top of the outer side of the positioning slide plate 11; a limiting cam 29 is fixedly mounted at the top end of the switching rotating shaft 28. Start the pushing cylinder body 5 to drive the connecting bracket 17, the feed slide plate 6 and the two positioning slide plates 11 to move downward. During the movement, the conversion slide column 9 will slide from the conversion inclined groove 4 to the guiding vertical groove 3, so that the conversion slide column 9 drives the two positioning slide plates 11 to move relatively inward while moving downward by using the inclined structure of the conversion inclined groove 4, and the positioning die A 13 and the positioning die B 15 move inward and merge, so as to stably position the wireless charging coil to be tinned by using the positioning convex block 16 and the positioning cushion block 14, and ensure the stability during the tinning process of the wireless charging coil.

[0023] Embodiment 2: On the basis of Embodiment 1, a downward pressure baffle 2 is fixedly installed inside the positioning base 1; the conversion inclined groove 4 is of an inclined structure; the lowest end of the conversion inclined groove 4 is communicated with the highest end of the guiding vertical groove 3; the top of the positioning base 1 is fixedly installed with pushing cylinders 5 on the left and right sides; the conversion sliding column 9 is of a cylindrical structure; the outer end of the conversion sliding column 9 is also slidably installed in the guiding groove structure jointly formed by the guiding vertical groove 3 and the conversion inclined groove 4; an embedded part 10 is fixedly installed at the outer end of the conversion sliding column 9; a spring A18 is jointly embedded between two adjacent embedded parts 10. When the positioning slide plate 11 moves downward, the pressure receiving wheel 22 will gradually not be pressed downward by the downward pressure baffle 2, so that the pressure receiving slide plate 20 can drive the conversion convex column 23 to move upward under the action of the spring B21, and the conversion convex column 23 drives the conversion rotating shaft 25, the limiting rotating shaft 24 and the sprocket A27 to rotate by using the semi-spiral structure of the conversion thread groove 26 through upward movement, and the sprocket A27 drives the sprocket B30, the switching rotating shaft 28 and the limiting cam 29 to rotate under the action of the chain, so that they rotate and resist above the positioning die A13 and the positioning die B15, ensuring the stability of the die structure during the tin dipping process.

[0024] Embodiment 3: On the basis of Embodiment 2, a wireless charging coil is buckled on the positioning convex block 16; the top of the connecting bracket 17 is connected to the output end of the pushing cylinder 5; the pressure receiving slide plate 20 is of an L-shaped structure; a spring B21 is jointly embedded between the bent part of the pressure receiving slide plate 20 and the top end of the embedded sliding groove 19; the pressure receiving wheel 22 is located below the downward pressure baffle 2; the pressure receiving wheel 22 is rotatably installed at the top end of the pressure receiving slide plate 20; the inner end of the conversion convex column 23 is of a hemispherical structure; the conversion thread groove 26 is of a semi-spiral structure; the hemispherical structure of the conversion convex column 23 is also slidably installed inside the conversion thread groove 26; a sprocket A27 is fixedly installed on the circumferential outer wall of the limiting rotating shaft 24; the limiting cam 29 is located above the positioning clamping groove 12; a sprocket B30 is fixedly installed on the circumferential outer wall of the switching rotating shaft 28; the sprocket B30 is connected to the sprocket A27 through a chain. After the tin dipping is completed, when the pushing cylinder 5 is restored, the corresponding positioning slide plate 11 and the limiting cam 29 and other structures will also be restored accordingly. The two restored positioning slide plates 11 are opened, facilitating the removal of the wireless charging coil after the tin dipping is completed, and the restored limiting cam 29 will cancel the resistance positioning of the positioning die A13 and the positioning die B15, facilitating the replacement of the die structure.

[0025] Working principle of this embodiment: Before soldering immersion, first fixedly install the positioning base 1 above the soldering immersion furnace. After installation, snap the wireless charging coil to be soldered onto the positioning bump 16, and then start the pushing cylinder body 5 to drive the connecting bracket 17, the feeding slide plate 6, and the two positioning slide plates 11 to move downward. During the movement, the conversion sliding column 9 will slide from the conversion inclined groove 4 into the guiding vertical groove 3, causing the conversion sliding column 9 to utilize the inclined structure of the conversion inclined groove 4 to drive the two positioning slide plates 11 to move relatively inward while moving downward, so that the positioning die A 13 and the positioning die B 15 move inward and merge, thereby stably positioning the wireless charging coil to be soldered using the positioning bump 16 and the positioning cushion block 14, ensuring the stability of the wireless charging coil during the soldering immersion process. And when the positioning slide plate 11 moves downward, the pressure-receiving runner 22 will gradually not be pressed by the downward pressure baffle 2, enabling the pressure-receiving slide plate 20 to drive the conversion convex column 23 to move upward under the action of the spring B 21. The conversion convex column 23 moves upward to drive the conversion rotating shaft 25, the limiting rotating shaft 24, and the sprocket A 27 to rotate by utilizing the semi-spiral structure of the conversion thread groove 26, causing the sprocket A 27 to drive the sprocket B 30, the switching rotating shaft 28, and the limiting cam 29 to rotate through the chain, so that they rotate and resist above the positioning die A 13 and the positioning die B 15 to ensure the stability of the die structure during the soldering immersion process. After the soldering immersion is completed, when the pushing cylinder body 5 is restored, the corresponding positioning slide plate 11, the limiting cam 29 and other structures will also be restored accordingly. The two restored positioning slide plates 11 are opened, facilitating the removal of the wireless charging coil after soldering immersion, and the restored limiting cam 29 will cancel the resistance positioning of the positioning die A 13 and the positioning die B 15, facilitating the replacement of the die structure.
