[0002] In the production process of mobile phone lens motors, it is necessary to solder the lead wires. The lead wire specification used in the lens motor of a certain mobile phone is an ultra-fine copper wire with a diameter of 0.14mm.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0049] Please see Figure 1This invention provides a wire feeding and insertion device for ultra-fine copper wires, comprising a feeding mechanism 100, a wire feeding mechanism 200, and a insertion mechanism 300 arranged from top to bottom. The feeding mechanism 100 and the wire feeding mechanism 200 are jointly mounted on a frame, while the insertion mechanism 300 is separately configured. Due to the complex structure of the entire device, the separately configured insertion mechanism 300 reduces the difficulty of overall assembly. This ultra-fine copper wire feeding and insertion device combines the feeding mechanism 100, the wire feeding mechanism 200, and the insertion mechanism 300 to achieve automated feeding and insertion of ultra-fine copper wires (0.14mm in diameter) into mobile phone motors, offering advantages of high efficiency and low rejection rate.

[0050] The feeding mechanism 100 includes a feeding tray 110, a guide 120, and a tray motor 130 for driving the feeding tray 110. That is, the feeding mechanism 100 adopts an active feeding method. Figure 2 As shown, the feeding tray 110 is located at the top of the frame, and the tray motor 130 is located on one side of the feeding tray 110. The output shaft of the tray motor 130 is directly connected to the rotation center of the feeding tray 110 through a flexible coupling to drive the feeding tray 110 to rotate. The guide 120 is located slightly below the feeding tray 110. The copper wire coming out of the feeding tray 110 passes through the guide 120 and then enters the wire feeding mechanism 200. Since the copper wire in this embodiment has a diameter of 0.14mm, it is very easy to break or be damaged. Since the feeding tray 110 has a certain width, it needs to be guided before entering the wire feeding mechanism 200 to accurately guide the ultra-fine copper wire into the wire feeding mechanism 200.

[0051] like Figure 3 As shown, the guide 120 is V-shaped, wider at the top and narrower at the bottom. The larger opening at the top is the wire inlet 1211, and the wire outlet 1212 is located at the bottommost sharp corner of the V-shape. Specifically, the guide 120 consists of a V-shaped guide housing 121 formed by folding two plates. The upper part is open, and the lower part is connected. The width of the upper part is the same as the width of the feeding tray 110, and the lower edge is aligned with the inlet of the wire feeding mechanism 200. Two guide posts 122 are provided at the upper edge and near the lower edge, one long and one short, to smoothly guide the copper wire without damaging it. The copper wire routing is as follows... Figure 4 As shown, at the bottom of the guide housing 121, that is, at the lowest position of the V-shaped structure, there is a hollow opening, which is the guide detection port 1213. A slack detector 123 is set at the guide detection port 1213. The slack detector 123 is a micro-photoelectric sensor. When the feed tray 110 rotates too much, resulting in too much wire being fed, the copper wire in the wire guide 120 will become slack. Figure 4As shown by the dotted line (the thick solid line represents the normal copper wire routing path), the copper wire will be detected by the relaxation detector 123 at this time, and the feed pan 110 will reverse to take in the material until the copper wire is tightened. Since the copper wire is unwound in the form of a coil, the rotation angle of the feed pan 110 is fixed when it actively unwinds. However, as the unwinding progresses, the diameter of the coil will change. Therefore, the length of the same coil will gradually decrease each time it is unwound. So, there must be a certain redundancy in each unwinding. The function of the relaxation detector 123 is to eliminate the influence of unwinding redundancy.

[0052] like Figure 5 As shown, the wire feeding mechanism 200 includes a copper wire fixing clamp 210, an air-blowing wire feeding mechanism 220, a winding mechanism 230, and a wire cutting mechanism 240 arranged from top to bottom. The ultra-fine copper wire passes through the above-mentioned parts in sequence to realize the complete wire feeding process.

[0053] like Figure 6 As shown, the copper wire clamp 210 includes a clamp base 211 and a clamp head 212. The clamp base 211 is fixed, while the clamp head 212 is movable relative to the clamp base 211. The clamp head 212 is fixed to the overall mechanism via a clamp head pivot 215. The clamp head 212 rotates around the clamp head pivot 215. Specifically, clockwise rotation of the clamp head 212 loosens the clamp, and counterclockwise rotation tightens the clamp. The driving mechanism for its movement consists of a clamp cylinder 213 and a clamp spring 214. Figure 6 As shown, the fixing clamp cylinder 213 and the fixing clamp spring 214 are both located on one side of the chuck shaft 215 and opposite to the clamp seat 211. When the piston of the fixing clamp cylinder 213 extends, the end of the chuck 212 is not under force. Under the elastic force of the fixing clamp spring 214, the chuck 212 rotates counterclockwise, and the fixing clamp clamps the copper wire. When the piston of the fixing clamp cylinder 213 retracts, the end of the chuck 212 is subjected to tension, overcoming the elastic force of the fixing clamp spring 214 to rotate clockwise, and the fixing clamp releases. The function of setting the copper wire fixing clamp 210 is to fix the copper wire entering the wire feeding mechanism 200, thereby further limiting the length of each feeding by the feeding mechanism 100, and ensuring that the copper wire is not easily loosened or bent in the wire feeding mechanism 200, thus avoiding quality problems.

[0054] Furthermore, at the top of the clamp 211, a clamp guide rod 2111 is provided. The direction of the clamp guide rod 2111 is consistent with the direction of the guide post 122 in the guide 120, and their functions are the same, both being to change the direction of the copper wire and achieve the purpose of smoothly guiding the copper wire. Furthermore, the wire pressing surface 2112 located below the clamp guide rod 2111 and in contact with the clamp 212 is not vertical but slightly inclined. The angle between the wire pressing surface 2112 and the horizontal plane is an obtuse angle. In other words, the clamp 212... When in contact with the wire pressing surface 2112, the working part of the chuck 212 just slides through the second quadrant and points to the position of the third quadrant. Because the chuck 212 is rotating, when the wire pressing surface 2112 is inclined as described above, the working part of the chuck 212 will be loose at the top and tight at the bottom when it contacts the wire pressing surface 2112. That is to say, the inclined wire pressing surface 2112 will block the rotation of the chuck 212, and the counterclockwise rotation force of the chuck 212 comes from the fixed clamping spring 214, which achieves a good clamping effect on the copper wire.

[0055] like Figures 6-7 As shown, below the copper wire clamp 210, an air-blowing wire feeding mechanism 220 is provided. The air-blowing wire feeding mechanism 220 is a block-shaped part with an internal channel, which is a Y-shaped air passage 221. The Y-shaped air passage 221 includes a wire feeding inlet 2211, a wire feeding air inlet 2212, and a wire feeding outlet 2213. The three outlets correspond to the three endpoints of the Y. The wire feeding inlet 2211 and the wire feeding outlet 2213 are located on a straight line, as shown in the figure. Figure 7 As shown, the copper wire comes down from the copper wire fixing clamp 210, enters the air-blowing wire feeder 220 through the wire inlet 2211, and is then sent out through the wire outlet 2213. At the same time, compressed air is blown in through the wire inlet 2212. Due to the Y-shaped air passage structure, the compressed air blown in through the wire inlet 2212 will only be blown out through the wire outlet 2213. Furthermore, due to the influence of the airflow velocity and direction in the passage, the air will also be passively drawn in through the wire inlet 2211 and move along the wire feeding path, thereby achieving the effect of air-blowing wire feeding.

[0056] like Figure 8 As shown, after passing through the air-blowing wire feeding mechanism 220, the copper wire reaches the winding mechanism 230. The winding mechanism 230 includes a winding mechanism base plate 231 and a winding mechanism cover plate 232. After the two are assembled, a cavity 233 is formed between them. The cavity 233 is an isosceles trapezoid. The two vertices of the lower base (longer) of the cavity 233 are the inlet and outlet of the copper wire, respectively. The size of the inlet and outlet is relatively small to reduce the efficiency of gas entry and exit and reduce the impact of air blowing. Furthermore, in the cavity 233, near the two vertices of the upper base of the trapezoid, a winding post 234 is provided. The copper wire runs in the cavity 233 as follows: Figure 9As shown, a cavity air inlet 235 is provided in the middle of the lower bottom of the cavity 233 for blowing compressed air into the cavity 233, and a cavity air outlet 236 is correspondingly provided at the upper bottom of the cavity 233, so that the gas flow direction in the cavity 233 is as follows: Figure 9 As shown, its function is to use gas to pull the copper wire, drawing the copper wire delivered by the air-blowing wire feeding mechanism 200 into the cavity 233; furthermore, a copper wire detector 237 is provided at the copper wire inlet of the cavity 233, for reference. Figure 9 The diagram shows the wiring path (the thick solid line represents the copper wire path, and the dashed arrows represent the airflow direction). When the copper wire enters the cavity 233 and passes around the first winding post 234, it will be detected by the copper wire detector 237. Therefore, the copper wire detector 237 is used to detect whether there is a break in the copper wire.

[0057] like Figure 10 As shown, the wire cutting mechanism 240 is located below the winding mechanism 230, with its inlet corresponding to the outlet at the bottom of the cavity 233, and is used to cut the copper wire. The wire cutting mechanism 240 includes a wire feeder 241, a wire threading plate 242, a cutter 243, and a wire insertion detector 244. After the copper wire comes out of the winding mechanism 230, it enters the wire feeder 241, then passes through the wire threading plate 242 and reaches the cutter 243. The wire insertion mechanism 300 receives the copper wire below the cutter 243, and the wire insertion detector 244 is used to detect whether the copper wire is received by the wire insertion mechanism 300. The cutter 243 is driven by a cylinder and is in close contact with the lower surface of the wire threading plate 242. Because the copper wire is too thin, it can only be cut at the wire hole 2421; otherwise, the copper wire will not be able to withstand the force and will be easily damaged.

[0058] Furthermore, the insertion detector 244, located below the wire hole 2421, can move along the direction of the copper wire. Its purpose is to avoid gaps and leave space for the insertion mechanism 300 to receive the copper wire extending from the wire hole 2421.

[0059] like Figure 11 As shown, the wire insertion mechanism 300 is located below the wire cutting mechanism 240. The wire insertion mechanism 300 includes a bottom base 330, a displacement mechanism 310 mounted on the base 330, and a wire inserter 320 located at the output end of the displacement mechanism 310. Specifically, the base 330 is inclined to accommodate the inclined wire hole on the motor. Therefore, the entire wire inserter 320 has a certain angle, as does the wire insertion action and direction. Furthermore, the displacement mechanism 310 consists of two mutually perpendicular linear modules, commonly referred to as the XY axis. The wire inserter 320 is displaced under the drive of the XY axis. The displacement plane is perpendicular to the wire insertion direction of the wire inserter 320, that is, the wire insertion direction of the wire inserter 320 is the normal to the displacement plane.

[0060] like Figure 12As shown, the connector 320 includes a pin 321 and an air nozzle 322. The air nozzle 322 is located above the pin 321 and is mounted on the output end of a horizontally mounted cylinder. The fixed end of the cylinder is mounted on a vertical guide rail, allowing the air nozzle 322 to extend, retract, and rise. The extension function is to prevent air from entering when the pin 321 moves below the wire cutting mechanism 240 to connect wires. The rising function can be understood as moving away from or closer to the pin 321.

[0061] The pin 321 is fixed to the slide rail where the air nozzle 322 is located by a slider, that is, the two are on the same rail. A spring pull pin 324 is provided on the pin 321. The pin 321 is suspended from the fixed part of the connector 320 by the insertion spring 323. Figure 12 As shown, the insertion pin 321 is suspended on the track by the elastic force of the insertion spring 323, which can play a buffering role during the insertion action to prevent the pin from breaking.

[0062] Combined with appendix Figures 1-12 The operation flow of this invention is as follows:

[0063] The feed tray 110 unwinds the copper wire, which enters the guide 120 from the guide inlet 1211, and then... Figure 4 In the circuit, the copper wire, in an S-shape, passes around two conductor posts 122, extends from the guide outlet 1212, and passes around the clamping conductor rod 2111 of the copper wire fixing clamp 210. It then enters the air-blowing wire feeding mechanism 220, entering through the wire inlet 2211 and exiting through the wire outlet 2213. Compressed air is blown in from the wire inlet 2212 and out from the wire outlet 2213, actuating the copper wire to perform the feeding action. The copper wire exiting from the wire outlet 2213 enters the winding mechanism 230. Figure 9The path shown extends from the winding mechanism 230 after bypassing the two winding posts 234. The compressed air flow in the winding mechanism 230 is synchronized with the airflow of the air-blowing wire feeding mechanism 220, pulling the copper wire fed by the air-blowing wire feeding mechanism 220 into the winding mechanism 230. The copper wire fed from the winding mechanism 230 enters the wire feeder 241 of the wire cutting mechanism 240. The wire feeder 241 also feeds the wire by air blowing. The air blowing process is synchronized with the air-blowing wire feeding mechanism 220 and the winding mechanism 230, feeding the copper wire into the insertion pin 321 of the insertion mechanism 300. During this process, it needs to pass through the wire guide plate 242. The wire hole 2421 on the wire guide plate 242 is aligned with the entrance of the insertion pin 321. The role of the wire guide plate 242 in the wire feeding process is to provide a guide plate. The wire outlet is accurately located, so the diameter of the wire hole 2421 is approximately the same as the diameter of the copper wire. After the copper wire inserted into the pin 321 is detected by the copper wire detector 237 and confirmed to be in place, the copper wire fixing clamp 210 clamps the copper wire. At the same time, the air blowing and wire feeding mechanism 220, the winding mechanism 230, and the wire feeder 241 simultaneously stop the air blowing and wire feeding action, and the cutter 243 moves to cut the copper wire. Finally, the displacement mechanism 310 of the insertion mechanism 300 operates, aligning the pin 321 with the position on the motor where the wire is to be inserted. The air nozzle 322 moves to the entrance of the pin 321 and blows air to feed the copper wire in the pin 321 into the motor wire hole. Then it returns to the bottom of the cutting mechanism 240, waiting for the next copper wire to be fed into the pin 321, completing one cycle.

[0064] The clamping process of the copper wire fixing clamp 210: The piston of the fixing frame cylinder 213 extends, the tail end of the clamp 212 is unrestrained, and under the elastic force of the fixing clamp spring 214, its tail end is lifted up. The entire clamp 212 rotates around the clamp shaft 215 as the rotation center. The head end of the clamp 212 moves downward and contacts the wire pressing surface 2112 to clamp the copper wire.

[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
