[0002] The automatic wire feeding device of a semi-automatic electric motor soldering machine is an automated mechanical component used to assist the soldering process. Its main function is to accurately and stably deliver solder wire to the soldering point, and work with the soldering gun or soldering head to complete the soldering operation.

[0003] Utility model disclosure (CN202571521U) discloses an automatic wire feeding device for a semi-automatic soldering machine, including a frame and a servo motor. A wire feeding bracket is fixedly mounted on the frame, and a wire feeding roller is fitted onto the wire feeding bracket. Solder wire is wound on the wire feeding roller, with one end of the solder wire passing through a hole in the middle of the frame. A servo motor is fixedly mounted on one side of the hole in the frame, and a transmission wheel is fixedly mounted on the shaft of the servo motor. A pressure roller is located above the transmission wheel, and a soldering head is fixedly mounted on one side of the servo motor. This utility model offers fast soldering speed and ease of use.

Furthermore, after prolonged use, the wire feeding function is prone to instability, resulting in low efficiency. Therefore, we propose an automatic wire feeding device for a semi-automatic soldering machine powered by a motor. Utility Model Content

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] like Figures 1-4As shown, this embodiment proposes an automatic wire feeding device for a semi-automatic soldering machine for motors, including a base plate 1, a support column 2 fixedly connected to the bottom of the base plate 1, a foot pad 3 fixedly connected to the bottom of the support column 2, a feeding box 4 fixedly connected to the bottom of the base plate 1, a control panel 5 provided on the side of the feeding box 4, a button 6 provided on the side of the control panel 5, and a wire feeding device 7 provided inside the feeding box 4.

[0028] The wire feeding device 7 includes a connecting plate 701, which is fixedly connected to the inner wall of the feeding box 4. A support plate 702 is fixedly connected to the side of the connecting plate 701. A rotating plate 703 is fixedly connected to the top of the support plate 702. A rotating column 704 is rotatably connected to the side of the rotating plate 703. A feeding wheel 705 is fixedly connected to one end of the rotating column 704. A feeding hole 706 is opened on the side of the feeding box 4. A conveying plate 707 is fixedly connected to the side of the feeding box 4. A wire feeding tube 708 is fixedly connected to the side of the conveying plate 707. A motor 709 is fixedly connected to the top of the bottom plate 1. A transmission wheel 710 is fixedly connected to the output shaft of the motor 709. An auxiliary wire feeding shaft 711 is rotatably connected to the inner side of the feeding box 4.

[0029] A wire feeding wheel 8 is fixedly connected to the circumference of the auxiliary wire feeding shaft 711. An auxiliary wire feeding tube 9 is fixedly connected to the side of the feeding box 4. Its function is to increase the stability of wire feeding.

[0030] The circumferential surface of the rotating column 704 penetrates the side surface of the rotating plate 703, and the output shaft of the motor 709 penetrates the side surface of the conveying plate 707. Their function is to make the equipment run more stably.

[0031] The circumferential surface of the auxiliary wire feeding shaft 711 penetrates the side of the feeding box 4. The number of motors 709 and transmission wheels 710 is set in groups of three, symmetrically arranged along the central axis of the conveyor plate 707, which increases the efficiency of the work.

[0032] In this embodiment, the motor 709 is started by the control panel 5. The output shaft of the motor 709 drives the transmission wheel 710 to rotate, which in turn drives the wire feeding device 7 to start working. The feeding wheel 705 rotates under the drive of the rotating column 704, pulling the wire out from the feeding box 4 through the feeding hole 706 and conveying it along the conveying plate 707 and the wire feeding tube 708. At the same time, the wire feeding wheel 8 on the auxiliary wire feeding shaft 711 cooperates with the wire feeding tube 708 to assist in the conveying of the wire.

[0033] Example 2

[0034] like Figures 1-4As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a tension adjustment device 10. The tension adjustment device 10 is provided on the top of the feeding box 4. The tension adjustment device 10 includes a contact plate 101. The bottom of the contact plate 101 is fixedly connected to the top of the feeding box 4. A return spring 102 is fixedly connected to the side of the contact plate 101. A contact rod 103 is fixedly connected to the end of the return spring 102 away from the contact plate 101. A trigger plate 104 is fixedly connected to the circumferential surface of the contact rod 103. A second motor 105 is fixedly connected to the inner side of the feeding box 4. A threaded rod 106 is fixedly connected to the output shaft of the second motor 105. An adjustment plate 107 is threadedly connected to the circumferential surface of the threaded rod 106. A limit post 108 is fixedly connected to the inner side of the feeding box 4. An adjustment switch 109 is provided on the side of the second motor 105. The tension is adjusted by adjusting the adjustment switch 109 according to the wire slack and the degree of advancement of the contact rod 103.

[0035] A slide plate 11 is fixedly connected to the inner side of the feeding box 4. The end of the threaded rod 106 away from the motor 105 is rotatably connected to a limit sleeve 12, which restricts its working position.

[0036] The end of the limiting sleeve 12 away from the threaded rod 106 is fixedly connected to the inner side of the feeding box 4, which makes the equipment run more stably.

[0037] The trigger end of the regulating switch 109 is located on the displacement trajectory of the side of the contact rod 103. The side cross section of the contact rod 103 is set in an L shape, which is used to increase the efficiency of the operation.

[0038] In this embodiment, when the wire allowance is too large or too small, the contact rod 103 will be squeezed or released by the wire, and thus move under the action of the return spring 102. The movement of the contact rod 103 will drive the trigger plate 104 to move together. When the trigger plate 104 touches the trigger end of the adjustment switch 109, it will trigger the adjustment switch 109 to act. After the adjustment switch 109 is triggered, the motor 105 will be started. The output shaft of the motor 105 will drive the threaded rod 106 to rotate. Since the threaded rod 106 and the adjustment plate 107 are connected by a thread, the rotation of the threaded rod 106 will drive the adjustment plate 107 to move. The movement of the adjustment plate 107 will change its distance from the inner side of the feed box 4, thereby adjusting the tightness of the wire.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
