Description

Technical Field

[0001] The present invention relates to the technical field of wire plugging machines, and in particular to a wire plugging machine capable of automatically winding wires. Background Art

[0002] Lead welding is a critical step in the production process of mobile phone lens motors. The lead wires of lens motors used in some mobile phones are made of ultra-fine copper wires with a diameter of only 0.1-0.2mm. This ultra-fine copper wire has good conductivity and flexibility, which can meet the needs of complex wiring and efficient signal transmission of lens motors in a small space.

[0003] Before welding, the ultra-fine copper wire needs to be precisely cut to the appropriate length and accurately inserted into the lead hole of the lens motor. This process requires extremely high quality of the copper wire. Not only does it require the copper wire to be precisely adapted in length, but it also needs to be free of creases, scratches, and other external injuries. Any slight damage may affect the 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 ultra-fine copper wire, since the ultra-fine copper wire is wound on a reel during storage, the long-term winding state of the copper wire makes it have a certain curvature. In industrial production, in order to achieve efficient wire feeding, pneumatic conveying is generally used for copper wire transportation. In this process, the curvature of the copper wire makes it difficult to maintain stable straightness and centering in the pneumatic channel. Driven by high-speed airflow, the curved copper wire is very easy to scratch against the channel wall. This scratching will not only leave scratches on the copper wire and reduce its surface quality, but may also cause local deformation of the copper wire, affecting its internal structure and conductivity, and affecting product quality and production efficiency.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] An embodiment of a wire inserting machine capable of automatically winding a wire of the present invention is as follows Figures 1 to 12 shown.

[0022] A wire plugging machine capable of automatically winding wires comprises a bracket 100 and a wire feeding mechanism 200, wherein the wire feeding mechanism 200 comprises a winding wheel 210, a guide wheel 220, a correction wheel 230 and a guide wheel 240. The winding wheel 210, the guide wheel 220, the correction wheel 230 and the guide wheel 240 are all arranged in a horizontal direction, and the axial direction of the guide wheel 220 is referred to as a first direction. The winding wheel 210 is mounted on the bracket 100, and a copper wire 300 is wound on the winding wheel 210. The guide wheel 220 and the correction wheel 230 are arranged side by side on the bracket 100 along a second direction, and the second direction is a horizontal direction and perpendicular to the first direction. The guide wheel 220 is located on the side of the correction wheel 230 close to the winding wheel 210 in the second direction, and the diameters of the guide wheel 220 and the correction wheel 230 are equal. The guide wheel 240 is mounted on the bracket 100. The diameter of the guide wheel 240 is larger than the diameter of the correction wheel 230. The guide wheel 240 is located on the side of the correction wheel 230 away from the guide wheel 220 in the second direction. The guide wheel 240 can revolve around the axis of the correction wheel 230. The free end of the copper wire 300 and the guide wheel 220 are sequentially arranged in the third direction, which is the vertical direction. The free end of the copper wire 300 is located above the guide wheel 220. The free end of the copper wire 300 is wound upwardly on the guide wheel 220, then wound downwardly on the correction wheel 230, and then wound upwardly on the guide wheel 240.

[0023] Furthermore, the guide wheel 220 and the correction wheel 230 abut against each other, and the guide wheel 240 abuts against the correction wheel 230. When the guide wheel 240 revolves around the axis of the correction wheel 230, the abutment point between the guide wheel 240 and the correction wheel 230 can be adjusted. The free end of the copper wire 300 is wound upwardly on the guide wheel 220, and after passing through the abutment between the guide wheel 220 and the correction wheel 230, it is wound downwardly on the correction wheel 230, and after passing through the abutment between the guide wheel 240 and the correction wheel 230, it is wound upwardly on the guide wheel 240.

[0024] In this embodiment, the winding wheel 210, the guide wheel 220, the correction wheel 230 and the guide wheel 240 are arranged on the bracket 100 to cooperate. When the wire is supplied, the free end of the copper wire 300 is pulled out from the winding wheel 210. After the copper wire 300 is pulled out from the winding wheel 210, the free end of the copper wire 300 is wound upward on the guide wheel 220, that is, the copper wire 300 can be wound on the guide wheel 220 in an overlapping manner without changing the curvature of the copper wire 300. When passing through the abutment of the guide wheel 220 and the correction wheel 230, the copper wire 300 is wound downward on 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 calibrated 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 abutment between the guide wheel 240 and the correction wheel 230. Fig.12The guide wheel 220 and the correction wheel 230 are in contact with each other, and the correction wheel 230 and the guide wheel 240 are in contact with each other, so that the copper wire 300 can enter the correction wheel 230 after being pulled out from the guide wheel 220, and enter the guide wheel 240 after being pulled out from the correction wheel 230, thereby improving the tightness of the connection between the guide wheel 220, the correction wheel 230 and the guide wheel 240.

[0025] Since the diameter of the guide wheel 240 is larger than the diameter of the correction wheel 230, the guide wheel 240 can perform a micro-correction on the copper wire 300 at this time. This setting can prevent the correction wheel 230 from over-correcting and causing the copper wire 300 to bend in the reverse direction when reversely straightening the copper wire 300. In addition, the guide wheel 240 with a larger diameter can also guide the copper wire 300, so that the free end of the copper wire 300 naturally faces downward.

[0026] When in use, the abutment position of the correction wheel 230 and the guide wheel 240 can be adjusted according to the bending degree of the free end of the copper wire 300 after being pulled out from the guide wheel 240, thereby changing the length of the copper wire 300 wound on the correction wheel 230. By increasing or decreasing the length of the copper wire 300 wound on the correction wheel 230, the correction wheel 230 can be used to neutralize the situation that the copper wire 300 may be reversely bent or the copper wire 300 cannot be corrected. The over-correction method is used to release the stress of the copper wire 300, and the over-correction intensity is controlled to adapt to the original stress of the copper wire 300, thereby improving the straightness of the copper wire 300 after correction and preventing over-correction or under-correction.

[0027] In a further embodiment, the bracket 100 is provided with an adjustment slot 110 , which is an arc-shaped slot, and the adjustment slot 110 is coaxially arranged with the correction wheel 230 . The guide wheel 240 is slidably installed in the adjustment slot 110 .

[0028] Specifically, a hydraulic telescopic cylinder 150 is provided on the bracket 100, and an adjusting rod 160 is provided at the output end of the hydraulic telescopic cylinder 150. An adjusting slide is provided on the adjusting rod 160, and the adjusting slide is arranged along the second direction. The axle of the guide wheel 240 passes through the adjusting groove 110 and the adjusting slide in sequence along the first direction, so that when the hydraulic telescopic cylinder 150 drives the adjusting rod 160 to move up and down, the guide wheel 240 can slide in the adjusting slide while sliding in the adjusting groove 110.

[0029] Alternatively, the guide wheel 240 may also be driven to slide in the adjustment slot 110 by a sprocket or a magnetic track.

[0030] In a further embodiment, a wire insertion machine capable of automatically winding wires further includes a control system, and the portion of the copper wire 300 extending through the guide wheel 240 is called a calibration line segment. A visual laser sensor is provided on the bracket 100, and the visual laser sensor is not shown in the attached drawings. The visual laser sensor is electrically connected to the control system, and the visual laser sensor can capture the curvature of the calibration line segment, and convert the captured signal 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 calibration line segment captured by the visual laser sensor.

[0031] By setting up a visual laser sensor, after the visual laser sensor captures the curvature of the calibration straight 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 slideway and the adjustment groove 110 at the same time, thereby changing the abutment position of the correction wheel 230 and the guide wheel 240, and then changing the length of the copper wire 300 wound on the correction wheel 230. By increasing or decreasing the length of the copper wire 300 wound on the correction wheel 230, the correction wheel 230 may neutralize the situation that the copper wire 300 may cause the reverse bending of the copper wire 300 and the copper wire 300 cannot be corrected, thereby improving the straightness of the calibration straight section.

[0032] In a further embodiment, the guide wheel 220 , the correction wheel 230 and the guide wheel 240 are all rotatable around their own axes, and the guide wheel 220 , the correction wheel 230 and the guide wheel 240 rotate at the same linear speed.

The bracket 100 is also provided with a third motor, the guide wheel 240 is coaxially and fixedly provided with a fifth gear 241, 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, the rotation speed of the third motor is less than the rotation speed of the first motor, and the linear speeds of the guide wheel 220, the correction wheel 230 and the guide wheel 240 are made to rotate at the same speed.

[0034] The third motor is electrically connected to the hydraulic telescopic cylinder 150, so that when the hydraulic telescopic cylinder 150 is started to rotate the guide wheel 240 from top to bottom in the adjustment groove 110, the control system can drive the third motor to increase the speed, and after the adjustment motor stops, the third motor restores the initial speed, so that the copper wire 300 can move with the guide wheel 240.

[0035] Alternatively, in another possible embodiment, the bracket 100 is provided with a first motor, the output shaft of the first motor is provided with a first gear, the guide wheel 220 is coaxially and fixedly provided with a second gear 221, and the first gear and the second gear 221 are meshed. The correction wheel 230 is coaxially and fixedly provided with a fourth gear 231, the second gear 221 and the fourth gear 231 are meshed, the diameter of the second gear 221 is the same as the diameter of the fourth gear 231, and the second gear 221 can drive the fourth gear 231 to rotate, the bracket 100 is rotatably provided with a synchronous gear 170, the synchronous gear 170 is meshed with the fourth gear 231, the guide wheel 240 is coaxially and fixedly provided with a fifth gear 241, the fifth gear 241 is meshed with the synchronous gear 170, the diameter of the fourth gear 231 is smaller than the diameter of the fifth gear 241, and the linear speeds of the guide wheel 220, the correction wheel 230 and the guide wheel 240 are the same.

[0036] By driving the guide wheel 220, the correction wheel 230 and the guide wheel 240 to rotate and making the linear speeds 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 feed 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 reduced as much as possible, thereby reducing the damage of the copper wire 300 that may be caused by friction.

[0037] In a further embodiment, mounting grooves are provided on the outer peripheral walls of the guide wheel 220, the correction wheel 230 and the guide wheel 240, and two airbags 250 are placed in each mounting groove. The two airbags 250 are arranged face to face in the first direction, and there is always positive pressure in the airbags 250. A receiving groove 251 for receiving the copper wire 300 is defined between the two airbags 250, so that when the copper wire 300 is placed in the receiving groove 251, the copper wire 300 can be squeezed under the pressure of the airbag 250 to prevent the copper wire 300 from twisting.

[0038] The airbag 250 is made of a highly elastic and wear-resistant material (such as rubber or polyurethane) to ensure its durability and stability.

[0039] In a further embodiment, the bracket 100 is provided with a first lead wheel 120, a second lead wheel 130 and a third lead wheel 140.

[0047] In this embodiment, by providing the first lead wheel 120, the second lead wheel 130 and the third lead wheel 140, when 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 airbags 250 of the guide wheel 220, so as to assist the winding of the copper wire 300 and prevent the pressure of the airbag 250 from hindering the installation of the copper wire 300. That is, the free end of the copper wire 300 can pass through the wire inlet hole 121 of the first lead wheel 120 and be pulled out from the wire outlet hole 122 where it is located, so that the pulled copper wire 300 can be placed in the receiving groove 251 of the guide wheel 220.

[0048] When the copper wire 300 wound on the guide wheel 220 comes to the second lead wheel 130, the second lead wheel 130 can first temporarily separate the two air bags 250 of the guide wheel 220, and assist the operator to pull out the copper wire 300, and pass the free end of the copper wire 300 through the wire inlet hole 121 of the second lead wheel 130, and pull it out from the wire outlet hole 122 where it is located, so that the pulled-out copper wire 300 can be placed in the accommodating groove 251 of the correction wheel 230.

[0049] Similarly, when the copper wire 300 wound on the correction wheel 230 comes to the third lead wheel 140, the third lead wheel 140 can first temporarily separate the two air bags 250 of the correction wheel 230, and assist the operator to pull out the copper wire 300, and pass the free end of the copper wire 300 through the wire inlet hole 121 of the third lead wheel 140, and pull it out from the wire outlet hole 122 where it is located, so that the pulled-out copper wire 300 can be placed in the accommodating groove 251 of the guide wheel 240.

[0050] In a further embodiment, a wire insertion machine capable of automatically winding wires further includes a wire feeding mechanism 400 and a wire insertion mechanism, both of which are prior art. The wire feeding mechanism 400 and the wire insertion mechanism are both mounted 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 alignment line segment can enter the wire feeding mechanism 400. The wire feeding mechanism 400 performs a wire feeding action in a pneumatic conveying manner, and delivers the copper wire 300 to the pin of the wire insertion mechanism, and further blows the copper wire 300 in the pin into the motor wire hole to complete the wire insertion.

[0051] In combination with the above embodiments, the specific working process is as follows: When supplying the wire, the free end of the copper wire 300 is pulled out from the winding wheel 210. After the copper wire 300 is pulled out from the winding wheel 210, the free end of the copper wire 300 is wound upward on the guide wheel 220, that is, the copper wire 300 can be wound on the guide wheel 220 in an overlapping manner without changing the curvature of the copper wire 300. And when passing through the abutment between the guide wheel 220 and the correction wheel 230, the copper wire 300 is wound downward on the correction wheel 230. 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 on the guide wheel 240 in an upward winding manner after passing through the abutment between the guide wheel 240 and the correction wheel 230. See the attached figure for details of the copper wire 300 after winding. Fig.12 shown.

[0052] Since the diameter of the guide wheel 240 is larger than the diameter of the correction wheel 230, the guide wheel 240 can perform a micro-correction on the copper wire 300 at this time. This setting can prevent the correction wheel 230 from over-correcting and causing the copper wire 300 to bend in the reverse direction when reversely straightening the copper wire 300. In addition, the guide wheel 240 with a larger diameter can also guide the copper wire 300, so that the free end of the copper wire 300 naturally faces downward.

[0053] When in use, after the visual laser sensor captures the curvature of the calibration 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 slideway and the adjustment groove 110 at the same time, thereby changing the abutment position of the correction wheel 230 and the guide wheel 240, and then changing the length of the copper wire 300 wound on the correction wheel 230. By increasing or decreasing the length of the copper wire 300 wound on the correction wheel 230, the correction wheel 230 may neutralize the situation that the copper wire 300 may cause the reverse bending of the copper wire 300 and the copper wire 300 cannot be corrected, thereby improving the straightness of the calibration line segment.

[0054] After the free end of the copper wire 300 is sent out from the guide wheel 240, it can enter the wire feeding mechanism 400. The wire feeding mechanism 400 performs the wire feeding action by pneumatic conveying, and sends the copper wire 300 to the pin of the wire insertion mechanism, and further blows the copper wire 300 in the pin into the motor wire hole to complete the wire insertion.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
