[0014] The beneficial effects of the present invention are as follows: 1. The present invention provides a wire pulling assembly. When the ejection frame contacts the outer side of the wire paying assembly, the ejection frame drives the piston plate to push the hydraulic oil in the sliding cylinder into the bent pipe, and the wire clamping component can clamp the ear wire out of the wire paying assembly. In this process, the ejection block pushes the clamping block upward during the movement, and finally the clamping block is clamped in the groove opened on the top of the ejection block, thereby locking the position of the ejection block, thereby preventing the ejection frame from resetting when it is separated from the wire paying assembly, and at the same time, the wire clamping component can always maintain a clamping state when the wire pulling assembly is reset, and clamp the ear wire out of the wire paying assembly, thereby providing ear wires for the mask during welding.

[0015] 2. The present invention sets a wire clamping component, and the ejector rod slides out of the bent pipe under the push of hydraulic oil, and at the same time pushes the connecting plate to drive the positioning rod to slide in the limit frame. At this time, the connecting plate approaches the auxiliary roller, and at the same time, under the restriction of the auxiliary roller, the clamping blocks on both sides of the connecting plate approach each other, thereby allowing the wire pulling assembly to automatically clamp and pull out the ear wire during the movement.

[0016] 3. The present invention provides a wire clamping component, guides the connecting plate through a positioning rod, and provides an auxiliary roller to reduce the friction resistance of the clamping block during operation, thereby increasing the service life of the clamping block. The coil spring is provided to drive the clamping block to reset when the ejection rod is reset, and the coil spring is protected by a sliding sleeve so that the coil spring will not bend outward when compressed.

[0017] 4. The present invention sets a wire pulling assembly. After the wire pulling assembly is reset, the protrusion on the top of the limit plate pushes the clamping block to slide upward along the guide rod and disengage from the groove on the top of the ejection block. At this time, under the elastic force of the compression spring, the ejection frame can drive the ejection block to reset, and the wire clamping component can automatically loosen the pulled ear wire, so that when the ear wire is positioned later, the wire clamping component will not tear the ear wire off.

[0018] 5. The present invention arranges a wire pulling assembly. When the ejection frame contacts the outer side of the wire releasing assembly, under the limiting action of the limit block and the insert block, the insert blocks on both sides of the shell drive the two positioning plates to move away from each other, thereby reserving sufficient space for the operation of the wire clamping component. After the wire pulling assembly is reset, the positioning plates on both sides approach each other as the ejection frame is reset, and after the wire clamping component releases the ear wire, the ear wire is auxiliary positioned to prevent the ear wire from rebounding after the ear wire is released by the wire clamping component.

[0019] 6. The present invention provides a pay-off assembly. When the pay-off assembly is in use, the plug plate is slid upward to release the restriction of the take-up shell on the pay-off wheel. Then, the flip plate is rotated upward. At this time, the pay-off wheel can be taken out of the take-up shell, and the ear hook line is wound around the surface of the pay-off wheel. In this way, the ear hook line can be loaded. The operation process is simple and easy to use.

[0020] 7. The present invention provides a wire-paying assembly, guides the ear hook wire through a guiding component, and finally passes the ear hook wire through a threading ring. At this time, the thread end of the ear hook wire is located on the outside of the wire-paying assembly, so that the wire clamping component can clamp the ear hook wire. At the same time, the ear hook wire is guided by providing an elastic sheet. When the ear hook wire breaks, the elastic sheet can prevent the ear hook wire from rebounding and retract into the wire-paying assembly, resulting in the wire clamping component being unable to clamp the ear hook wire.

[0021] 8. The present invention provides a guide component. When in use, the guide component allows the ear hook wire to pass between the guide wheel and the pressure wheel at the top of the support frame. At this time, under the restriction of the mounting plate, the elastic plate presses the limiting ring downward, so that the pressure wheel presses the ear hook wire and the guide wheel tightly. In this way, the ear hook wire can be guided by the guide wheel, and the pressure wheel can prevent the ear hook wire from detaching from the guide wheel.

[0022] 9. The present invention sets a welding device, and the servo motor drives the positioning shell to deflect, so that the elastic clamp block is kept horizontal with the ear line, and then the telescopic cylinder located inside the shell drives the sliding plate to move downward. When the bottom of the elastic clamp block is horizontal with the ear line, the telescopic rod is extended, so that the elastic clamp blocks on both sides are close to each other, and the ear line is fixed. At the same time, as the clamping force of the elastic clamp block increases, the ear line can be clamped off under the mutual squeezing of the elastic clamp blocks on both sides, and then the servo motor drives the elastic clamp block to reset, so that the two ends of the ear line correspond to the position of the mask.

The ear hook line 636 is then wound around the surface of the pay-off wheel 634, and the ear hook line 636 is thereby loaded. The operation process is simple and easy to use. The ear hook line 636 is then guided by the guide component 635, and finally the ear hook line 636 is passed through the threading ring 637. At this time, the thread end of the ear hook line 636 is located on the outside of the pay-off assembly 63, so that the clamping component 660 can clamp the ear hook line 636. At the same time, the ear hook line 636 is guided by the elastic sheet 638. When the ear hook line 636 breaks, the elastic sheet 638 can prevent the ear hook line 636 from rebounding and retracting into the pay-off assembly 63, resulting in the inability of the clamping component 660 to clamp the ear hook line 636.

[0031] The guide component 635 includes a support frame 351, the inner wall of the support frame 351 is rotatably connected to a guide wheel 352, the inner wall of the support frame 351 is slidably connected to a pressure wheel 356, the outer wall of the pressure wheel 356 is rotatably connected to a limit ring 355, the top of the limit ring 355 is fixedly connected to an elastic plate 354, the top of the elastic plate 354 is fixedly connected to a mounting plate 353, the top of the mounting plate 353 is fixedly connected to the inner wall of the take-up shell 631, and the bottom of the inner wall of the take-up shell 631 is fixedly connected to the support frame 35 1, when the guide component 635 is in use, the ear hanging wire 636 passes through between the guide wheel 352 and the pressure wheel 356 at the top of the support frame 351. At this time, under the restriction of the mounting plate 353, the elastic plate 354 presses the limiting ring 355 downward, so that the pressure wheel 356 presses the ear hanging wire 636 and the guide wheel 352 tightly, thereby guiding the ear hanging wire 636 through the guide wheel 352, and preventing the ear hanging wire 636 from being separated from the guide wheel 352 through the pressure wheel 356.

[0032] Working principle: When in use, the base 1 is supported by the support legs 2, and then the mask is placed on the surface of the storage table 3 on the top of the base 1, and then the ear wires are provided for the mask by the ear wire supply device 6, and then the ear wires and the mask are welded by the welding device 5 installed on the outside of the support plate 4, so that the automatic welding process can be completed; When the ear wire supply device 6 is in use, the driving motor 62 drives the screw 64 to rotate, so that the slider 65 slides along the sliding seat 61 to the side close to the wire release assembly 63, and at this time, the wire pulling assembly 66 slides together with the slider 65; When the ejection frame 662 contacts the outer side of the wire-releasing assembly 63, the ejection frame 662 drives the piston plate 664 to slide in the sliding cylinder 663, and pushes the hydraulic oil in the sliding cylinder 663 into the curved pipe 669 through the piston plate 664, so that the wire clamping component 660 can clamp the ear wire out of the wire-releasing assembly 63. In this process, the ejection block 666 moves with the ejection frame 662, and pushes the clamping block 667 upward during the movement, and finally, under the limiting action of the guide rod 668, the clamping block 667 is clamped in the groove opened at the top of the ejection block 666, thereby locking the position of the ejection block 666, thereby preventing the ejection frame 662 from resetting when it is separated from the wire-releasing assembly 63, and at the same time, the clamping component 660 can always maintain a clamped state when the wire-pulling assembly 66 is reset, and clamp the ear wire out of the wire-releasing assembly 63, thereby providing an ear wire for the mask during welding; During this process, the ejector rod 601 slides out of the bent pipe 669 under the push of the hydraulic oil, and at the same time pushes the connecting plate 602 to drive the positioning rod 604 to slide in the limit frame 605. At this time, the connecting plate 602 approaches the auxiliary roller 606. At the same time, under the restriction of the auxiliary roller 606, the clamping blocks 603 on both sides of the connecting plate 602 approach each other, so that the wire pulling assembly 66 can automatically clamp and pull out the ear wire during the movement; The connection plate 602 is guided by providing a positioning rod 604, and the friction resistance of the clamping block 603 during operation is reduced by providing an auxiliary roller 606, thereby increasing the service life of the clamping block 603. The clamping block 603 is driven to reset when the ejection rod 601 is reset by providing a coil spring 608, and the coil spring 608 is protected by a sliding sleeve 607, so that the coil spring 608 does not bend outward when compressed. After the wire pulling assembly 66 is reset, the protrusion on the top of the limit plate 67 can contact the inclined surface of the protrusion on the top of the clamping block 667, and at the same time, the clamping block 667 is pushed to slide upward along the guide rod 668 and disengage from the groove on the top of the ejection block 666. At this time, under the elastic force of the compression spring 665, the ejection frame 662 can drive the ejection block 666 to reset, and the clamping component 660 can automatically loosen the pulled ear wire, so that when the ear wire is positioned later, the clamping component 660 will not tear the ear wire off; When the ejection frame 662 contacts the outer side of the wire-releasing assembly 63, under the limiting action of the limit block 621 and the insert block 625, the connecting rod 624 slides along the surface of the cross bar 622 through the sliding frame 623. At this time, the insert blocks 625 on both sides of the housing 661 drive the two positioning plates 626 to move away from each other, leaving enough space for the operation of the wire clamping component 660. After the wire pulling component 66 is reset, the positioning plates 626 on both sides move closer to each other as the ejection frame 662 is reset, and after the wire clamping component 660 releases the ear wire, the ear wire is auxiliary positioned to prevent the ear wire from rebounding after the ear wire is released by the wire clamping component 660. When the pay-off assembly 63 is in use, the plug plate 633 is slid upward to release the restriction of the take-up shell 631 on the pay-off wheel 634, and then the flip plate 632 is rotated upward, and the pay-off wheel 634 can be taken out from the take-up shell 631, and the ear hook line 636 is wound around the surface of the pay-off wheel 634, so that the ear hook line 636 can be loaded, and the operation process is simple and easy to use; Then, the ear hook wire 636 is guided by the guide component 635, and finally the ear hook wire 636 is passed through the threading ring 637. At this time, the thread end of the ear hook wire 636 is located outside the wire-releasing assembly 63, so that the wire clamping component 660 can clamp the ear hook wire 636. At the same time, the ear hook wire 636 is guided by the elastic sheet 638. When the ear hook wire 636 breaks, the elastic sheet 638 can prevent the ear hook wire 636 from rebounding and retracting into the wire-releasing assembly 63, so that the wire clamping component 660 cannot clamp the ear hook wire 636. When the guide component 635 is in use, the ear hook wire 636 passes between the guide wheel 352 and the pressure wheel 356 at the top of the support frame 351. At this time, the elastic plate 354 presses the limiting ring 355 downward under the restriction of the mounting plate 353, so that the pressure wheel 356 presses the ear hook wire 636 and the guide wheel 352 tightly. In this way, the ear hook wire 636 can be guided by the guide wheel 352, and the pressure wheel 356 prevents the ear hook wire 636 from being separated from the guide wheel 352. After the wire pulling assembly 66 pulls the ear wire out of the wire releasing assembly 63, the servo motor 54 drives the positioning shell 56 to deflect, so that the elastic clamp block 58 is kept level with the ear wire, and then the telescopic cylinder 52 located inside the shell 51 drives the sliding plate 53 to move downward. When the bottom of the elastic clamp block 58 is level with the ear wire, the telescopic rod 57 is extended, so that the elastic clamp blocks 58 on both sides are close to each other to fix the ear wire. At the same time, as the clamping force of the elastic clamp block 58 increases, the ear wire can be clamped off under the mutual squeezing of the elastic clamp blocks 58 on both sides, and then the servo motor 54 drives the elastic clamp block 58 to reset, so that the two ends of the ear wire correspond to the position of the mask, and the mask and the ear wire can be welded by the welding gun 55.
