[0034] Please refer to Figures 1 to 6As shown in the figure, the present utility model proposes a wire pulling device 100 for processing inductors after winding. The wire pulling device 100 includes a frame, a positioning device 1 and a wire pulling device 2. The positioning device 1 is connected to the frame. A placement surface 11 is provided on the side of the positioning device 1 facing away from the frame. The placement surface 11 is used for placing the base. The positioning device 1 is provided with a wire pulling cavity 16 penetrating through the placement surface 11. The wire pulling cavity 16 is used for accommodating the pins of the inductor; the wire pulling device 2 includes a driving component 21 and a wire pulling member provided on the frame. The wire pulling member is provided with a clamping cavity 214. The clamping cavity 214 is used for clamping or releasing the wire feet; wherein, the driving component 21 drives the wire pulling member to approach or move away from the wire pulling cavity 16 to achieve wire pulling.

[0035] In this embodiment, the positioning device 1 is used for placing and fixing the base and the coil. When the wire pulling device 100 pulls the wire of the inductor, the wound coil and the base are moved to the placement surface 11 of the positioning device 1 manually or automatically, and the pins of the base are inserted into the wire pulling cavity 16 penetrating through the placement surface 11. The excess wire feet among the wire feet wound around the pins extend out from the orifice of the wire pulling cavity 16. Then, the driving component 21 drives the wire pulling member to approach the wire pulling cavity 16, and drives the wire pulling member to clamp the wire feet extending out of the wire pulling cavity 16 into the clamping cavity 214. The driving component 21 then drives the wire pulling member to drive the wire feet away from the wire pulling cavity 16 to complete wire pulling.

[0036] In actual implementation, after the pins are inserted into the wire pulling cavity 16, the groove wall of the wire pulling cavity 16 plays a limiting role on the pins and the wire feet wound thereon. The wire feet wound around the pins are limited between the pins and the groove wall of the wire pulling cavity 16 and are close to or in contact with the groove wall of the wire pulling cavity 16. In this way, when the wire pulling device 2 pulls the wire, there is resistance between the wound wire feet and the groove wall of the wire pulling cavity 16 to prevent the pulled wire feet from driving the pins to bend and be damaged. Optionally, the orifice of the wire pulling cavity 16 is flared to facilitate the insertion of the pins of the inductor into the wire pulling cavity 16.

[0037] In an embodiment of the present utility model, as Figures 1 to 3 shown, the positioning device 1 has a first side 12 and a second side 13 facing away from each other. The first side 12 and the second side 13 are located on both sides of the placement surface 11. There are multiple wire pulling cavities 16. The multiple wire pulling cavities 16 are respectively arranged on the positioning device 1 at intervals corresponding to the first side 12 and the second side 13.

[0038] In this embodiment, there are multiple wire-pulling cavities 16. The multiple wire-pulling cavities 16 are respectively arranged corresponding to the first side 12 and the second side 13 of the positioning device 1 to protect and limit multiple pins of the inductor simultaneously. It can be understood that the pins of the inductor can be divided into two sides according to their positions, and each side has multiple pins. When the inductor is placed on the placement surface 11, one side of the pins of the inductor extends into the wire-pulling cavity 16 corresponding to the first side 12, and the other side of the pins of the inductor extends into the wire-pulling cavity 16 corresponding to the second side 13. Each pin extends into a corresponding wire-pulling cavity 16, so as to realize the positioning placement of the inductor, avoid the displacement of the inductor during the wire-pulling process, and facilitate wire-pulling of the pins on the same side of the inductor simultaneously.

[0039] During actual implementation, the multiple wire-pulling cavities 16 corresponding to the first side 12 are arranged collinearly, the multiple wire-pulling cavities 16 corresponding to the second side 13 are arranged collinearly, and the connection line of the multiple wire-pulling cavities 16 corresponding to the first side 12 and the connection line of the multiple wire-pulling cavities 16 corresponding to the second side 13 are arranged in parallel. No specific limitation is made here. The extending direction of the wire-pulling cavity 16 is perpendicular or obtuse to the plane where the placement surface 11 is located to ensure the wire-pulling effect on the pins.

[0040] In an embodiment of the present utility model, as Figure 3 and Figure 4 shown, the positioning device 1 includes a positioning block 14 and a pin protection component 15. The positioning block 14 is connected to the frame and is provided with a placement surface 11 and a wire-pulling groove 141 communicating with the placement surface 11. The pin protection component 15 includes a pin protection driving member 151 and a pin protection plate 152. The pin protection driving member 151 is connected to the frame, and the pin protection plate 152 is connected to the output end of the pin protection driving member 151. Among them, the pin protection driving member 151 drives the pin protection plate 152 to approach the wire-pulling groove 141 to enclose and form a wire-pulling cavity 16.

[0041] In this embodiment, the positioning block 14 is provided with a placement surface 11 for the inductor and a wire-pulling groove 141 communicating with the placement surface 11. When the inductor is placed on the placement surface 11, the pins extend into the wire-pulling groove 141 of the positioning block 14. Then, the pin protection driving member 151 drives the pin protection plate 152 to approach the wire-pulling groove 141 to cover the notch of the wire-pulling groove 141 and enclose to form a wire-pulling cavity 16, thereby protecting and limiting the pins. The pins first extend into the wire-pulling groove 141, and then the pin protection plate 152 approaches the wire-pulling groove 141 to enclose and form the wire-pulling cavity 16, which can effectively reduce the difficulty of the pins extending into the wire-pulling cavity 16.

[0042] In actual implementation, the cross-sectional shape of the wire pulling groove 141 can be set to be semi-circular. The wire pulling cavities 16 corresponding to the first side 12 and the second side 13 of the positioning device 1 of the foot protection assembly 15 are respectively arranged. Alternatively, there are two foot protection plates 152, which are correspondingly arranged on the first side 12 and the second side 13. The two foot protection plates 152 are connected to the output end of the foot protection driving member 151. The foot protection driving member 151 drives the two foot protection plates 152 to approach each other, so as to approach the wire pulling grooves 141 corresponding to the first side 12 and the second side 13 respectively, and then enclose to form the wire pulling cavities 16 corresponding to the first side 12 and the second side 13.

[0043] In an embodiment of the present utility model, as Figure 3 and Figure 4 shown, the positioning block 14 includes two mounting portions 142 and a limiting portion 143 arranged between the two mounting portions 142. The mounting portion 142 is connected to the frame. The surface of the limiting portion 143 facing away from the frame is the placing surface 11. The limiting portion 143 and the mounting portion 142 enclose a limiting groove 144, and a wire pulling groove 141 is recessed at the bottom of the limiting groove 144.

[0044] In this embodiment, the limiting portion 143 is connected to the frame through the two mounting portions 142 to ensure the stability of the limiting portion 143 during installation. The surface of the limiting portion 143 facing away from the frame is the placing surface 11. When the inductor is placed on the placing surface 11, the inductor completely covers the placing surface 11. The protruding part at the bottom of the inductor can be limited in the limiting groove 144 formed by the limiting portion 143 and the mounting portion 142, thereby improving the stability of the inductor when placed on the placing surface 11 and preventing the inductor from shaking during wire pulling, which affects the wire pulling effect of the inductor. The wire pulling groove 141 is arranged at the bottom of the limiting groove 144 to facilitate the pins of the inductor to extend into the wire pulling groove 141. At the same time, when the foot protection plate 152 covers the limiting groove 144, the foot protection plate 152 can extend into the limiting groove 144, and the limiting groove 144 plays an avoidance role for the foot protection plate 152.

[0045] In actual implementation, the two sides of the limiting portion 143 form the first side 12 and the second side 13. The mounting portion 142 includes a first section and a second section forming an included angle. The first section is connected to the frame, and the limiting portion 143 is connected to the second section, so that the two mounting portions 142 enclose an avoidance space to facilitate the installation and arrangement of the foot protection assembly 15.

[0046] In an embodiment of the present utility model, as Figure 5 and Figure 6 shown, the frame is provided with a slide rail 3. The driving assembly 21 includes a translation driving member 211 and a clamping driving member 212. The translation driving member 211 is connected to the frame. The clamping driving member 212 is slidably arranged on the slide rail 3 and is connected to the output end of the translation driving member 211. The wire pulling member is connected to the output end of the clamping driving member 212.

[0047] In this embodiment, the clamping driving member 212 is used to drive the wire pulling member to clamp or release the wire foot. The clamping driving member 212 is slidably disposed on the slide rail 3, and the translation driving member 211 is used to drive the clamping driving member 212 to move along the slide rail 3 so as to drive the wire pulling member to approach or move away from the wire pulling cavity 16. When pulling the feet of the inductor, after the inductor is placed, the translation driving member 211 drives the clamping driving member 212 to drive the wire pulling member to approach the wire pulling cavity 16 along the slide rail 3. When the wire pulling member reaches the preset position, the clamping driving member 212 drives the clamping member to clamp the redundant wire foot. Then, the translation driving member 211 drives the clamping driving member 212 to drive the wire pulling member to move away from the wire pulling cavity 16 along the slide rail 3 so that the wire foot is tightened and broken. After the wire foot is broken, the clamping driving member 212 drives the wire pulling member to release the broken wire foot for the next wire pulling. In actual implementation, the translation driving member 211 can be a cylinder or an inductor, etc., and no specific limitation is made here.

[0048] In an embodiment of the present utility model, as Figure 5 and Figure 6 shown, the wire pulling member includes two wire pulling arms 213. The two wire pulling arms 213 are connected to the output end of the clamping driving member 212, and the two wire pulling arms 213 enclose to form a clamping cavity 214.

[0049] In this embodiment, the wire pulling member is composed of two wire pulling arms 213. When the clamping driving member 212 drives the wire pulling member to clamp the wire foot, the wire foot is located between the two wire pulling arms 213. The clamping driving member 212 drives the two wire pulling arms 213 to approach each other to clamp the wire foot and limit the wire foot in the clamping cavity 214. When the wire pulling member releases the broken wire foot, the clamping driving member 212 drives the two wire pulling arms 213 to move away from each other to release the broken wire foot.

[0050] In an embodiment of the present utility model, as Figure 1 shown, the wire pulling device 2 includes at least two groups, and at least two groups of wire pulling devices 2 are respectively disposed on both sides of the positioning device 1.

[0051] In this embodiment, the wire pulling device 2 can include two groups to respectively pull the wire feet on both sides of the inductor, thereby improving the wire pulling efficiency of the inductor.

[0052] In an embodiment of the present utility model, as Figure 5 and Figure 6 shown, the clamping cavity 214 has a first cavity wall 215 and a second cavity wall 216 which are oppositely arranged. The first cavity wall 215 is provided with a wire pulling protrusion 217, and the second cavity wall 216 is provided with a wire pulling groove 218 corresponding to the wire pulling protrusion 217.

[0053] In this embodiment, the first chamber wall 215 and the second chamber wall 216 of the clamping chamber 214 are used to enclose and form the clamping chamber 214. The first chamber wall 215 and the second chamber wall 216 approach or move away from each other to change the width of the clamping chamber 214, thereby clamping or releasing the lead. The first chamber wall 215 and the second chamber wall 216 are respectively provided with a wire pulling protrusion 217 and a wire pulling groove 218. When the wire pulling member clamps the lead, the wire pulling protrusion 217 abuts against the lead and drives the lead to extend into the wire pulling groove 218, so as to ensure the stability and reliability of the wire pulling member clamping the lead.

[0054] In actual implementation, the first chamber wall 215 and the second chamber wall 216 of the clamping chamber 214 can respectively be the surfaces of two wire pulling arms 213 facing the clamping chamber 214. The wire pulling protrusions 217 can include multiple ones, and the multiple wire pulling protrusions 217 are arranged at intervals on the chamber wall of the clamping chamber 214. A wire pulling groove 218 is formed between adjacent wire pulling protrusions 217. The wire pulling protrusions 217 of the first chamber wall 215 and the second chamber wall 216 are arranged in a staggered manner. In this way, when the wire pulling member clamps the lead, the wire pulling protrusion 217 of the first chamber wall 215 extends into the wire pulling groove 218 of the second chamber wall 216, and the wire pulling protrusion 217 of the second chamber wall 216 extends into the wire pulling groove 218 of the first chamber wall 215.

[0055] In an embodiment of the present utility model, as Figure 5 and Figure 6 shown, the wire pulling device 2 further includes a brush plate 222 assembly 22. The brush plate 222 assembly 22 includes a brush plate 222 driving member 221 and a brush plate 222. The brush plate 222 driving member 221 is connected to the brush plate 222. Among them, the brush plate 222 driving member 221 drives the brush plate 222 to extend into the clamping chamber 214 to clean the clamping chamber 214.

[0056] In this embodiment, the wire pulling device 100 cleans the clamping chamber 214 after wire pulling through the brush plate 222 assembly 22. When the wire pulling device 2 finishes wire pulling on one side, the clamping chamber 214 opens, the first chamber wall 215 and the second chamber wall 216 move away from each other, the brush plate 222 driving member 221 drives the brush plate 222 to move towards the clamping chamber 214. After the brush plate 222 extends into the clamping chamber 214, the brush plate 222 abuts against the first chamber wall 215 and the second chamber wall 216. The brush plate 222 driving member 221 drives the brush plate 222 to reciprocate in the clamping chamber 214 to clean the residual leads on the first chamber wall 215 and the second chamber wall 216, so as to avoid affecting the next wire pulling of the wire pulling member.

[0057] In actual implementation, the brush plate 222 assembly 22 is arranged in one-to-one correspondence with the wire pulling member. The brush plate 222 can include two. The two brush plates 222 are respectively connected to the brush plate 222 driving member 221 corresponding to the first chamber wall 215 and the second chamber wall 216 to clean the first chamber wall 215 and the second chamber wall 216 simultaneously.

[0058] In an embodiment of the present utility model, the brush plate 222 is provided with a cleaning groove 2221 corresponding to the wire pulling protrusion 217, and the brush plate 222 is provided with a cleaning protrusion 2222 corresponding to the wire pulling groove 218.

[0059] In this embodiment, when the brush plate 222 cleans the clamping cavity 214, the cleaning protrusion 2222 of the brush plate 222 penetrates into the wire pulling groove 218. Correspondingly, the wire pulling protrusion 217 also penetrates into the cleaning groove 2221. In this way, the brush plate 222 comprehensively cleans the cavity wall of the clamping cavity 214.

[0060] During actual implementation, an aggregate member can be arranged below the clamping member to collect the wire end debris cleaned from the clamping cavity 214, keep the processing environment clean, and avoid the wire end debris from affecting the operation of the wire pulling device 100.

[0061] The above description is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
