[0042] As Figures 1-10 shown, an embodiment of the present invention provides an automatic supply device for tinned copper wires, including a first mounting plate 1, a second mounting plate 2, and a bottom plate 3. The first mounting plate 1 is slidably mounted on the bottom plate 3, the second mounting plate 2 is fixedly mounted on the bottom plate 3. A plurality of linkage gear disks 101 are arranged in a circular array on the first mounting plate 1. The linkage gear disks 101 are rotatably connected to the first mounting plate 1. A transmission gear ring 102 is rotatably connected to the middle of the first mounting plate 1. The transmission gear ring 102 is meshed with a plurality of linkage gear disks 101. A copper wire roller 103 is snap-connected to the end face of each linkage gear disk 101. A driving motor 104 is fixedly connected to the end face of the second mounting plate 2 close to the first mounting plate 1. A transmission shaft 105 is fixedly connected to the output end of the driving motor 104. The transmission shaft 105 is snap-connected to the inner peripheral wall of the transmission gear ring 102. A plurality of support plates 106 are fixedly connected to the tops of the first mounting plate 1 and the second mounting plate 2. A reciprocating translation assembly is arranged on the support plates 106. A plurality of guiding assemblies are arranged on the end face of the second mounting plate 2 away from the first mounting plate 1. The guiding assemblies are used to guide the releasing trajectory of the copper wires. The guiding assemblies include a traction assembly, and the traction assembly provides traction force for the release of the copper wires.

[0043] Specifically: Install the coiled copper wire coil on the copper wire roller 103, and then start the driving motor 104. The driving motor 104 drives the transmission shaft 105 to rotate. The transmission shaft 105 drives a plurality of linkage gear disks 101 to rotate through the transmission gear ring 102. The linkage gear disks 101 drive the copper wire rollers 103 to rotate, so that the copper wires are released from the copper wire rollers 103, and it is applicable to the simultaneous release of multiple copper wires, and the release rate is consistent, which improves the efficiency of copper wire supply;

[0044] When the twisting process is required for multiple copper wires, the simultaneous release of multiple wires can provide convenience for the twisting process of the copper wires;

[0045] The reciprocating translation assembly is used to control the release direction of the copper wires, so that the copper wires move towards the outside of the first mounting plate 1. Then, through the guiding assemblies, the multiple copper wires are made parallel. Finally, with the traction force of the traction assembly, the copper wires are released completely, so that the multiple copper wires can be released orderly and stably.

[0046] The guiding component further includes a cross plate 4. At the top of one end of the cross plate 4, a first bracket group 401 is fixedly connected. A first wire roller 402 is rotatably connected to the first bracket group 401. A second bracket group 403 is also fixedly connected to the top of the cross plate 4. A second wire roller 404 is rotatably connected to the end of the second bracket group 403.

[0047] The first wire roller 402 and the second wire roller 404 are at the same height.

[0048] The traction component includes a vertical plate 405. An installation frame 406 and an installation plate 407 are sequentially arranged on the vertical plate 405 from top to bottom. An output roller 408 is fixedly connected to the installation frame 406. A rotary motor 409 is also fixedly connected to the side wall of the installation frame 406. The output shaft of the rotary motor 409 is fixedly connected to the output roller 408. An installation block 410 is fixedly connected to the installation plate 407. A V-shaped side plate 417 is fixedly connected to the installation block 410. A linkage roller 411 and a guide roller 412 are respectively rotatably connected to the two ends of the V-shaped side plate 417. A through hole 413 is formed in the vertical plate 405.

[0049] Specifically: Through the first wire roller 402 and the second wire roller 404 at the same height, the released copper wire can be parallel. When the rotary motor 409 is started, it drives the output roller 408 to rotate. The linkage roller 411 provides a bottom support surface for the copper wire. The copper wire passes through between the output roller 408 and the linkage roller 411. Therefore, when the output roller 408 rotates, it can provide a traction force for the copper wire.

[0050] It can be understood that: When the copper wire passes through the space between the output roller 408 and the linkage roller 411, the copper wire is further supported by the guide roller 412, so that the copper wire can be basically in a horizontal state before entering below the output roller 408, thereby reducing frictional losses, ensuring the quality of the copper wire, and the traction is carried out simultaneously with the release of the copper wire, so the losses caused by traction are reduced to the lowest.

[0051] A plurality of grooves are formed in the inner peripheral wall of the through hole 413. A ball 414 is rotatably connected in each groove. The copper wire is supplied through the through hole 413. The ball 414 is used to reduce friction.

[0052] Two mounting ears 418 are symmetrically and fixedly connected to one end of the cross plate 4. A plurality of groups of slide rails are formed on the end face of the second mounting disk 2 away from the first mounting disk 1. Each group of slide rails is composed of two symmetrically arranged chutes 415. The mounting ears 418 slide and abut against the outer side surface of the chutes 415. An insertion hole 416 is formed in the mounting ears 418. A plurality of bayonet holes are formed in the through hole of the chute 415 from top to bottom. A bolt is inserted and connected in the insertion hole 416.

[0053] Specifically, in the copper wire supply work, by moving the height of the transverse plate 4, the overall supply height of the copper wire is changed, so as to adapt to different processing procedures, and the supply height can be adjusted according to actual needs, and it can adapt to various processing machines of different models. The height of the transverse plate 4 is stabilized by inserting a pin through the socket 416 and the bayonet.

[0054] The reciprocating translation assembly includes a lead screw 5, a lead screw sleeve 501 and a lead screw motor 502. The two ends of the lead screw 5 are rotatably connected to the support plate 106. The lead screw motor 502 is installed on the side wall of the support plate 106. The output shaft of the lead screw motor 502 is fixedly connected to the lead screw 5. The lead screw 5 is threadedly connected to the lead screw sleeve 501. A guide block 503 is fixedly connected to the lead screw sleeve 501. A guide port 504 for the copper wire to pass through is provided in the guide block 503.

[0055] Specifically, the lead screw motor 502 rotates reciprocally, thereby controlling the lead screw sleeve 501 and the guide block 503 to perform linear reciprocating movements, so that the guide block 503 can move synchronously with the release position of the copper wire, making the guiding work of the copper wire in the guide block 503 more smooth.

[0056] A plurality of clamping balls 6 are elastically connected to the outer peripheral wall of the transmission shaft 105. A plurality of linkage grooves 601 are provided on the inner peripheral wall of the transmission gear ring 102. The clamping balls 6 are clamped and connected to the linkage grooves 601.

[0057] A guide rail 7 is arranged on the top of the bottom plate 3. A slider 701 is fixedly connected to the bottom of the first mounting plate 1. The slider 701 is slidably connected to the guide rail 7.

[0058] Specifically, the clamping effect of the linkage gear disk 101 on the first mounting plate 1 is the same as the clamping effect of the transmission shaft 105 on the transmission gear ring 102. Then, the first mounting plate 1 can move along the guide rail 7 through the slider 701, so that the first mounting plate 1 and the second mounting plate 2 can be separated, facilitating the disassembly and assembly of the copper wire on the copper wire roller 103.

[0059] An elastic sleeve rod 8 is fixedly connected to the middle of the second support group 403. A tensioning roller 801 is rotatably connected to the end of the elastic sleeve rod 8. The elastic sleeve rod 8 is an elastic telescopic structure composed of two rod bodies and a spring. Under the elastic action, the elastic sleeve rod 8 can make the tensioning roller 801 press against the copper wire, ensuring the tension of the copper wire and making the release of the copper wire more stable.

[0060] Working principle: Install the coiled copper wire coil on the copper wire roller 103, then start the driving motor 104. The driving motor 104 starts to drive the transmission shaft 105 to rotate. The transmission shaft 105 drives a plurality of linkage gear disks 101 to rotate through the transmission gear ring 102. The linkage gear disks 101 drive the copper wire roller 103 to rotate, so that the copper wire is released from the copper wire roller 103, and it is applicable to the simultaneous release of multiple copper wires, and the release rate is consistent, which speeds up the efficiency of copper wire supply. When the twisting process is required for multiple copper wires, the simultaneous release of multiple wires can provide convenience for the twisting process of the copper wire.

[0061] During the wire release process, the lead screw motor 502 rotates reciprocally, thereby controlling the lead screw sleeve 501 and the guide block 503 to perform linear reciprocating movements. Thus, the guide block 503 can move synchronously with the release position of the copper wire, making the guiding work of the copper wire in the guide block 503 smoother. And when the copper wire passes through the space between the output roller 408 and the linkage roller 411, the copper wire is further supported by the guide roller 412, so that the copper wire can be basically in a horizontal state before entering below the output roller 408, thereby reducing frictional losses and ensuring the quality of the copper wire. And the traction is carried out simultaneously with the release of the copper wire, so the loss caused by the traction is reduced to the lowest.

[0062] In the copper wire supply work, by moving the height of the moving cross plate 4, the overall supply height of the copper wire is changed, so as to be able to adapt to different processing procedures, and the supply height can be adjusted according to actual needs, and it can adapt to various processing machines of different models. The height of the cross plate 4 is stabilized by inserting a pin through the socket 416 and the bayonet.

[0063] Finally, the slider 701 enables the first mounting plate 1 to move along the guide rail 7, so that the first mounting plate 1 and the second mounting plate 2 can be separated, facilitating the disassembly and assembly of the copper wire on the copper wire roller 103.

[0064] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
