Description
Technical Field
[0001] The present invention relates to the technical field of wire inserting machines, and particularly to a wire inserting machine capable of automatically winding wires. Background Art
[0002] In the production process of mobile phone lens motors, lead wire welding is a crucial link. For some lens motors used in mobile phones, the lead wires are made of ultra-fine copper wires with a diameter of only 0.1 - 0.2 mm. Such ultra-fine copper wires have good electrical conductivity and flexibility, and can meet the requirements of complex wiring in a small space and efficient signal transmission of the lens motor.
[0003] Before the welding operation, the ultra-fine copper wire needs to be precisely cut to an appropriate length and accurately inserted into the lead wire hole of the lens motor. This process has extremely high requirements for the quality of the copper wire. It not only requires the length of the copper wire to be precisely adapted, but also ensures that there are no external injuries such as creases and scratches. Any slight damage may affect the electrical conductivity and mechanical strength of the copper wire, thereby reducing the performance of the lens motor and even causing the product to be scrapped.
[0004] During the unwinding and feeding process of the ultra-fine copper wire, since the ultra-fine copper wire is wound on a spool during storage, and the long-term winding state of the copper wire gives it a certain curvature. In industrial production, in order to achieve efficient wire feeding, the copper wire is generally transported pneumatically. During this process, the curvature of the copper wire makes it difficult to maintain a stable straightness and centrality in the pneumatic channel. Under the push of high-speed air flow, the copper wire with curvature is extremely easy to scrape against the channel wall. This scraping will not only leave scratches on the copper wire, reducing its surface quality, but also may cause local deformation of the copper wire, affecting its internal structure and electrical conductivity, and affecting product quality and production efficiency. Summary of the Invention

Detailed implementation manners
[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0032] An embodiment of an automatic wire-winding wire inserter according to the present invention is as Figures 1 to 12 shown.
[0033] A wire plugging machine capable of automatically winding wires, comprising a bracket 100 and a wire supply mechanism 200. The wire supply mechanism 200 includes a wire winding wheel 210, a guiding wheel 220, a correcting wheel 230, and a guiding wheel 240. The wire winding wheel 210, the guiding wheel 220, the correcting wheel 230, and the guiding wheel 240 are all arranged in the horizontal direction, and the axial direction of the guiding wheel 220 is defined as the first direction. The wire winding wheel 210 is installed on the bracket 100, and a copper wire 300 is wound around the wire winding wheel 210. The guiding wheel 220 and the correcting wheel 230 are arranged side by side on the bracket 100 in the second direction, and the second direction is a horizontal direction perpendicular to the first direction. The guiding wheel 220 is located on the side of the correcting wheel 230 closer to the wire winding wheel 210 in the second direction, and the guiding wheel 220 and the correcting wheel 230 have the same diameter. The guiding wheel 240 is installed on the bracket 100, the diameter of the guiding wheel 240 is larger than that of the correcting wheel 230, the guiding wheel 240 is located on the side of the correcting wheel 230 away from the guiding wheel 220 in the second direction, and the guiding wheel 240 can revolve around the axis of the correcting wheel 230. The free end of the copper wire 300 and the guiding wheel 220 are arranged in sequence in the third direction, and the third direction is the vertical direction. The free end of the copper wire 300 is located above the guiding wheel 220. The free end of the copper wire 300 is wound upward around the guiding wheel 220 and then downward around the correcting wheel 230, and then upward around the guiding wheel 240.
[0034] Furthermore, the guiding wheel 220 and the correcting wheel 230 are in contact with each other, and the guiding wheel 240 and the correcting wheel 230 are in contact with each other. When the guiding wheel 240 revolves around the axis of the correcting wheel 230, the contact point between the guiding wheel 240 and the correcting wheel 230 can be adjusted. The free end of the copper wire 300 is wound upward around the guiding wheel 220, and after passing through the contact point between the guiding wheel 220 and the correcting wheel 230, it is wound downward around the correcting wheel 230, and after passing through the contact point between the guiding wheel 240 and the correcting wheel 230, it is wound upward around the guiding wheel 240.
[0035] In this embodiment, by arranging the wire winding wheel 210, the guiding wheel 220, the correcting wheel 230, and the guiding wheel 240 on the bracket 100 in cooperation, when supplying wire, the free end of the copper wire 300 is pulled out from the wire winding wheel 210. After the copper wire 300 is pulled out from the wire winding wheel 210, the free end of the copper wire 300 is wound upward around the guiding wheel 220, that is, the copper wire 300 can be wound around the guiding wheel 220 in a lapping manner without changing the curvature of the copper wire 300. And when passing through the contact point between the guiding wheel 220 and the correcting wheel 230, the copper wire 300 is wound downward around the correcting wheel 230, and the correcting wheel 230 will correct the copper wire 300 in a reverse correction manner to straighten the copper wire 300. After being corrected by the correcting wheel 230, the copper wire 300 will continue to be wound upward around the guiding wheel 240 after passing through the contact point between the guiding wheel 240 and the correcting wheel 230. For the wound copper wire 300, see the appendix Figure 12As shown in the figure. By making the guide wheel 220 and the calibration wheel 230 abut against each other, and the calibration wheel 230 and the guide wheel 240 abut against each other, it is possible to make the copper wire 300 enter the calibration wheel 230 after being pulled out from the guide wheel 220, and enter the guide wheel 240 after being pulled out from the calibration wheel 230, improving the tightness of the connection between the copper wire 300 among the guide wheel 220, the calibration wheel 230 and the guide wheel 240.
[0036] Since the diameter of the guide wheel 240 is larger than that of the calibration wheel 230, at this time, the guide wheel 240 can further micro-calibrate the copper wire 300. This setting can prevent the calibration wheel 230 from over-correcting and causing the copper wire 300 to bend in the reverse direction when straightening the copper wire 300 in the reverse direction. Moreover, the guide wheel 240 with a larger diameter can also play a guiding role for the copper wire 300, making the free end of the copper wire 300 face downward naturally.
[0037] And during use, according to the bending degree of the free end of the copper wire 300 after being pulled out from the guide wheel 240, the abutting position of the calibration wheel 230 and the guide wheel 240 can be adjusted, thereby changing the length of the copper wire 300 wound around the calibration wheel 230. By increasing or decreasing the length of the copper wire 300 wound around the calibration wheel 230, the situation where the calibration wheel 230 may cause the copper wire 300 to bend in the reverse direction and the copper wire 300 fails to be calibrated can be neutralized. The over-correction method is used to release the stress of the copper wire 300, and by controlling the over-correction intensity, the original stress of the copper wire 300 is adapted, improving the straightness of the copper wire 300 after calibration and preventing the situation of over-calibration or insufficient calibration.
[0038] In a further embodiment, an adjustment groove 110 is formed on the bracket 100. The adjustment groove 110 is an arc-shaped groove and is coaxially arranged with the calibration wheel 230. The guide wheel 240 is slidably installed in the adjustment groove 110.
[0039] Specifically, a hydraulic telescopic cylinder 150 is arranged on the bracket 100. The output end of the hydraulic telescopic cylinder 150 is provided with an adjustment rod 160. An adjustment slideway is formed on the adjustment rod 160. The adjustment slideway is arranged along the second direction. The axle of the guide wheel 240 sequentially passes through the adjustment groove 110 and the adjustment slideway along the first direction. Thus, when the hydraulic telescopic cylinder 150 drives the adjustment rod 160 to move up and down, the guide wheel 240 can slide in the adjustment slideway while sliding in the adjustment groove 110.
[0040] Alternatively, the guide wheel 240 can also be driven to slide in the adjustment groove 110 by a sprocket or a magnetic track.
[0041] In a further embodiment, a wire plugging machine capable of automatically winding wires further includes a control system. The part of the copper wire 300 extending out through the guide wheel 240 is called the straightening section. A visual laser sensor is provided on the bracket 100, which is not shown in the attached drawings. The visual laser sensor is electrically connected to the control system. The visual laser sensor can capture the curvature of the straightening section and convert the signal it captures into a digital signal through an analog-to-digital converter (ADC) and transmit it to the control system. The control system can drive the hydraulic telescopic cylinder 150 to start according to the curvature of the straightening section captured by the visual laser sensor.
[0042] By setting the visual laser sensor, after the visual laser sensor captures the curvature of the straightening section, the control system is used to drive the hydraulic telescopic cylinder 150 to start, so that the guide wheel 240 can slide in the adjustment chute while sliding in the adjustment groove 110, changing the abutting position of the correction wheel 230 and the guide wheel 240, and further changing the length of the copper wire 300 wound around the correction wheel 230. By increasing or decreasing the length of the copper wire 300 wound around the correction wheel 230, the situation where the correction wheel 230 may cause the copper wire 300 to bend in the opposite direction and the copper wire 300 cannot be corrected is neutralized, and the straightness of the straightening section is improved.
[0043] In a further embodiment, the guide wheel 220, the correction wheel 230, and the guide wheel 240 are all rotatably arranged about their respective axes, and the linear velocities of the rotation of the guide wheel 220, the correction wheel 230, and the guide wheel 240 are the same.
[0044] Specifically, a first motor is provided on the bracket 100. A first gear is provided on the output shaft of the first motor. A second gear 221 is coaxially and fixedly provided on the guide wheel 220, and the first gear and the second gear 221 are meshed. A second motor is also provided on the bracket 100. A third gear is provided on the output shaft of the second motor. A fourth gear 231 is coaxially and fixedly provided on the correction wheel 230, and the third gear and the fourth gear 231 are meshed. A third motor is also provided on the bracket 100. A fifth gear 241 is coaxially and fixedly provided on the guide wheel 240, and the output shaft of the third motor is connected to the fifth gear 241 through a transmission belt. The rotation speed of the first motor is the same as the rotation speed of the second motor, and the rotation speed of the third motor is less than the rotation speed of the first motor, so that the linear velocities of the rotation of the guide wheel 220, the correction wheel 230, and the guide wheel 240 are the same.
[0045] The third motor is electrically connected to the hydraulic telescopic cylinder 150. Furthermore, when the hydraulic telescopic cylinder 150 starts and the guide wheel 240 rotates downward in the adjustment groove 110, the control system can drive the third motor to increase its speed, and after the adjustment motor stops, the third motor resumes its initial speed, so that the copper wire 300 can follow the guide wheel 240.
[0046] Alternatively, in another possible embodiment, a first motor is provided on the bracket 100. A first gear is provided on the output shaft of the first motor. A second gear 221 is coaxially and fixedly provided on the guide wheel 220. The first gear meshes with the second gear 221. A fourth gear 231 is coaxially and fixedly provided on the correction wheel 230. The second gear 221 meshes with the fourth gear 231. The diameter of the second gear 221 is the same as that of the fourth gear 231. The second gear 221 can drive the fourth gear 231 to rotate. A synchronous gear 170 is rotatably provided on the bracket 100. The synchronous gear 170 meshes with the fourth gear 231. A fifth gear 241 is coaxially and fixedly provided on the guide wheel 240. The fifth gear 241 meshes with the synchronous gear 170. The diameter of the fourth gear 231 is smaller than that of the fifth gear 241, and the linear speeds of the rotation of the guide wheel 220, the correction wheel 230, and the guide wheel 240 are made the same.
[0047] By driving the guide wheel 220, the correction wheel 230, and the guide wheel 240 to rotate and making the linear speeds of the rotation of the guide wheel 220, the correction wheel 230, and the guide wheel 240 the same, when the guide wheel 220, the correction wheel 230, and the guide wheel 240 rotate to supply the copper wire 300, the pulling force of the guide wheel 220, the correction wheel 230, and the guide wheel 240 on the copper wire 300 is minimized, and the situation of damage to the copper wire 300 caused by friction is reduced.
[0048] In a further embodiment, mounting grooves are provided on the outer peripheral wall surfaces of the guide wheel 220, the correction wheel 230, and the guide wheel 240. Two air bags 250 are placed in each mounting groove. The two air bags 250 are arranged face to face in a first direction, and the air bags 250 always have a positive pressure. A receiving groove 251 for receiving the copper wire 300 is defined between the two air bags 250. When the copper wire 300 is placed in the receiving groove 251, the copper wire 300 can be squeezed tightly under the action of the pressure of the air bags 250, preventing the copper wire 300 from twisting itself.
[0049] The air bags 250 are made of high-elasticity and wear-resistant materials (such as rubber or polyurethane) to ensure their durability and stability.
[0050] In a further embodiment, a first lead wheel 120, a second lead wheel 130, and a third lead wheel 140 are provided on the bracket 100. An inlet hole 121 and an outlet hole 122 are provided on the first lead wheel 120. The inlet hole 121 and the outlet hole 122 are communicated. The copper wire 300 can enter from one side of the inlet hole 121 and be pulled out from one side of the outlet hole 122. A wedge-shaped slope 123 is provided on the first lead wheel 120. The outlet hole 122 is located on one side of the wedge-shaped slope 123. The structures of the first lead wheel 120, the second lead wheel 130, and the third lead wheel 140 are the same.
[0051] The wedge-shaped slope surface 123 of the first lead wheel 120 is inserted into the accommodation groove 251 between the two air bags 250 of the guide wheel 220. The wire inlet hole 121 of the first lead wheel 120 is arranged on the side close to the winding wheel 210 in the second direction, and the wire inlet hole 121 of the first lead wheel 120 is located above its wire outlet hole 122.
[0052] The second lead wheel 130 is located at the abutting position between the guide wheel 220 and the calibration wheel 230. Or, the abutting position between the guide wheel 220 and the calibration wheel 230 is called the first abutting point. The second lead wheel 130 and the first abutting point are arranged in sequence in the direction in which the copper wire 300 is wound around the guide wheel 220, and the second lead wheel 130 is located behind the first abutting point. That is, the copper wire 300 is wound around the guide wheel 220 in the clockwise direction shown in the attached Figure 12 The direction close to the arrow side of the clockwise rotation in the winding direction is called the front, and the direction away from the arrow side of the clockwise rotation is called the back.
[0053] The second lead wheel 130 is inserted into the accommodation groove 251 between the two air bags 250 of the guide wheel 220. And the wedge-shaped slope surface 123 of the second lead wheel 130 is inserted into the accommodation groove 251 between the two air bags 250 of the calibration wheel 230. The wire inlet hole 121 of the second lead wheel 130 is located above its wire outlet hole 122.
[0054] The third lead wheel 140 is located at the abutting position between the calibration wheel 230 and the guide wheel 240. Or, the abutting position between the calibration wheel 230 and the guide wheel 240 is called the second abutting point. The third lead wheel 140 and the second abutting point are arranged in sequence in the direction in which the copper wire 300 is wound around the guide wheel 240, and the third lead wheel 140 is located behind the second abutting point. That is, the copper wire 300 is wound around the guide wheel 240 in the clockwise direction shown in the attached Figure 12 The direction close to the arrow side of the clockwise rotation in the winding direction is called the front, and the direction away from the arrow side of the clockwise rotation is called the back.
[0055] The third lead wheel 140 is inserted into the accommodation groove 251 between the two air bags 250 of the calibration wheel 230. And the wedge-shaped slope surface 123 of the third lead wheel 140 is inserted into the accommodation groove 251 between the two air bags 250 of the guide wheel 240. The wire inlet hole 121 of the third lead wheel 140 is located below its wire outlet hole 122.
[0056] In a further embodiment, the third lead wheel 140 can revolve and rotate around the axis of the calibration wheel 230 along with the guide wheel 240, so that the copper wire 300 can enter the guide wheel 240 after leaving the calibration wheel 230.
[0057] Specifically, a follow-up groove is formed in the bracket 100. The follow-up groove is an arc-shaped groove, and the follow-up groove and the adjustment groove 110 are coaxially arranged. A rack is arranged in the follow-up groove. The rack is arc-shaped and is arranged along the arc direction of the follow-up groove. A follow-up gear is coaxially and rotatably connected to the third lead wheel 140. The follow-up gear includes a smooth shaft section and a gear section arranged in sequence along the first direction. A follow-up motor is arranged on the bracket 100. The output shaft of the follow-up motor is connected to the smooth shaft section of the follow-up gear through a transmission belt. The gear section of the follow-up gear meshes with the rack, and the follow-up motor is electrically connected to the hydraulic telescopic cylinder 150. Thus, when the hydraulic telescopic cylinder 150 is started to drive the guide wheel 240 to move in the adjustment groove 110 and adjust the position where the guide wheel 240 and the correction wheel 230 are in contact, the follow-up motor can act synchronously, so that the third lead wheel 140 can revolve and rotate around the axis of the correction wheel 230 in the follow-up groove.
[0058] In this embodiment, by providing the first lead wheel 120, the second lead wheel 130 and the third lead wheel 140, after the free end of the copper wire 300 is pulled out from the winding wheel 210, the wedge-shaped slope 123 of the first lead wheel 120 is used to temporarily separate the two air bags 250 of the guide wheel 220 to assist in winding the copper wire 300 and prevent the pressure of the air bags 250 from hindering the installation of the copper wire 300. That is, the free end of the copper wire 300 can pass through the inlet hole 121 of the first lead wheel 120 and be pulled out from the outlet hole 122 where it is located, so that the pulled-out copper wire 300 can be placed in the receiving groove 251 of the guide wheel 220.
[0059] When the copper wire 300 wound around the guide wheel 220 reaches the second lead wheel 130, the second lead wheel 130 can first temporarily separate the two air bags 250 of the guide wheel 220, assist the operator in pulling out the copper wire 300, and pass the free end of the copper wire 300 through the inlet hole 121 of the second lead wheel 130 and pull it out from the outlet hole 122 where it is located, so that the pulled-out copper wire 300 can be placed in the receiving groove 251 of the correction wheel 230.
[0060] Similarly, when the copper wire 300 wound around the correction wheel 230 reaches the third lead wheel 140, the third lead wheel 140 can first temporarily separate the two air bags 250 of the correction wheel 230, assist the operator in pulling out the copper wire 300, and pass the free end of the copper wire 300 through the inlet hole 121 of the third lead wheel 140 and pull it out from the outlet hole 122 where it is located, so that the pulled-out copper wire 300 can be placed in the receiving groove 251 of the guide wheel 240.
[0061] In a further embodiment, a wire plugging machine capable of automatically coiling wires further includes a wire feeding mechanism 400 and a wire plugging mechanism, both of which are prior arts. The wire feeding mechanism 400 and the wire plugging mechanism are both installed on the bracket 100 and are located below the guide wheel 240. The free end of the copper wire 300 can enter the wire feeding mechanism 400 after being sent out from the guide wheel 240, that is, the straightened line segment can enter the wire feeding mechanism 400. The wire feeding mechanism 400 performs a wire feeding action in a pneumatic conveying manner, sends the copper wire 300 into the plug pin of the wire plugging mechanism, and further blows the copper wire 300 in the plug pin into the motor wire hole to complete wire plugging.
[0062] Combined with the above embodiments, the specific working process is as follows:
[0063] During wire supply, the free end of the copper wire 300 is pulled out from the wire winding wheel 210. After the copper wire 300 is pulled out from the wire winding wheel 210, the free end of the copper wire 300 is wound upward around the guide wheel 220, that is, the copper wire 300 can be wound around the guide wheel 220 in an overlapping manner without changing the curvature of the copper wire 300. And when passing through the contact position of the guide wheel 220 and the correction wheel 230, the copper wire 300 is wound downward around the correction wheel 230, and the correction wheel 230 will correct the copper wire 300 in a reverse correction manner to straighten the copper wire 300. After being corrected by the correction wheel 230, the copper wire 300 will continue to be wound around the guide wheel 240 in an upward winding manner after passing through the contact position of the guide wheel 240 and the correction wheel 230. The wound copper wire 300 is shown in the appendix Figure 12 as shown.
[0064] Since the diameter of the guide wheel 240 is larger than that of the correction wheel 230, at this time, the guide wheel 240 can further micro-correct the copper wire 300. This setting can prevent the correction wheel 230 from over-correcting the copper wire 300 and causing the copper wire 300 to bend reversely when performing reverse straightening on the copper wire 300. Moreover, the guide wheel 240 with a larger diameter can also play a guiding role for the copper wire 300, making the free end of the copper wire 300 face downward naturally.
[0065] And during use, after the visual laser sensor captures the curvature of the straightened line segment, the control system is used to drive the hydraulic telescopic cylinder 150 to start, so that the guide wheel 240 can slide in the adjustment chute and slide in the adjustment groove 110 at the same time, changing the contact position of the correction wheel 230 and the guide wheel 240, and further changing the length of the copper wire 300 wound around the correction wheel 230. By increasing or decreasing the length of the copper wire 300 wound around the correction wheel 230, the situation that the correction wheel 230 may cause the copper wire 300 to bend reversely and the copper wire 300 cannot be corrected is neutralized, and the straightness of the straightened line segment is improved.
[0066] After the free end of the copper wire 300 is sent out from the guide pulley 240, it can enter the wire feeding mechanism 400. The wire feeding mechanism 400 performs the wire feeding action in the way of pneumatic conveying, sends the copper wire 300 into the insertion needle of the wire insertion mechanism, and further blows the copper wire 300 in the insertion needle into the motor wire hole to complete the wire insertion.
[0067] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
