[0015] The present invention also discloses a wire laying method for precious metal wire processing, the specific steps of which are: The relative driven wheels are controlled to move away from each other by the positioning assembly, so that the winding drum can roll from one side of the bottom plate to the bottom plate and the lifting platform; The lifting platform is controlled by the lifting control component to lift the winding drum so that the upper part of the winding drum exceeds the height of the driving wheel and the driven wheel; The driving wheel and the driven wheel are controlled to approach each other through the clamping assembly so that the distance between the driving wheel and the driven wheel is smaller than the diameter of the winding drum; The relative driven wheels are controlled to approach each other by the positioning assembly so that the connecting plate contacts the side of the winding drum; The lifting platform is controlled to descend through the lifting control component, so that the driven wheel is mounted on the driving wheel and the driven wheel, and then the wire on the winding drum is pulled to the processing equipment through the tension balance mechanism.

[0016] Compared with the prior art, the present invention provides a wire-paying device and a wire-paying method for precious metal wire processing, which have the following beneficial effects: 1. The wire-releasing device is convenient for controlling the relative driven wheels to approach and move away from each other by setting a yielding component, so that when the winding reel is replaced, the winding reel can pass between the relative driven wheels and move to the lifting platform. By setting a lifting control component, it is convenient to lift the winding reel on the lifting platform. In conjunction with the setting of the clamping component, the driving wheel and the driven wheel can be controlled to approach and move away from each other, so that the winding reel lifted by the lifting platform can be quickly and conveniently set on the driving wheel and the driven wheel, and the rotation of the driving wheel drives the winding reel to rotate and release the wire, thereby facilitating accurate control of the wire-releasing speed of the winding reel.

[0017] 2. The wire-releasing device is convenient for controlling the rear bracket and the front bracket to move closer to and farther from each other by arranging guide rails, sliders, screw rods, clamping control motors and transmission short shafts, thereby realizing the spacing control of the driving wheel and the driven wheel, so as to support the winding drum rising upward from between the driving wheel and the driven wheel. The spacing between the front bracket and the connecting plate is conveniently controlled by arranging the front bracket, the connecting plate, the screw rods, the guide rods and the internal threaded tube. The relative driven wheels can be controlled to move closer to and farther from each other by coordinating the transmission long shaft and the yielding control motor. At the same time, due to the arrangement of the transmission short shaft and the transmission long shaft, the structures in the clamping assembly and the yielding assembly will not hinder the movement of the winding drum on the bottom plate, and the height of the bottom plate is too high due to too many structures on the lower surface of the bottom plate, thereby preventing the winding drum from being too difficult to move onto the bottom plate.

[0018] 3. The wire-releasing device can control the up and down movement of the lifting platform by arranging a threaded vertical rod, a lifting control motor and a nut. By arranging a through hole, a fixed shaft and a supporting wheel, the winding drum can be limited between the driving wheel and the driven wheel when it moves between the supporting wheels. When the winding drum rises to a suitable height, it can be simultaneously contacted by the driving wheel and the driven wheel that are close to each other, so that the winding drum will not fall or collide when the lifting platform descends and separates from the winding drum. At the same time, by arranging a positioning block and a spring, the supporting wheel is spaced apart from the side wall of the through hole when not affected by external force, so that when the driven wheels approach each other, the connecting plates on both sides push the winding drum to translate, so that the two ends of the winding drum are respectively in contact with the connecting plates on both sides, so that the winding drum will not undergo axial displacement during the rolling wire-releasing process.

[0021] 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.

[0022] Embodiment 1 See also Figure 1 , Figure 4 and Figure 6 The present invention provides a wire-releasing device, including a bottom plate 1 and a winding drum 9, the bottom plate 1 is provided with a driving wheel 2, a driven wheel 3, a lifting platform 4, a clamping assembly 5, a yielding assembly 6 and a lifting control assembly 7, the driving wheel 2 and the driven wheel 3 are both arranged on the bottom plate 1, the driven wheels 3 are respectively arranged on both sides of the bottom plate 1, the lifting platform 4 is arranged between the driving wheel 2 and the driven wheel 3, a rear bracket 21 is rotatably mounted on the driving wheel 2, a front bracket 31 is arranged on the driven wheel 3, a connecting plate 32 is slidably arranged on the front bracket 31, and the connecting plate 32 is rotatably connected to the driven wheel 3; The clamping assembly 5 is used to control the rear bracket 21 and the front bracket 31 to move closer to or farther from each other, so that the winding drum 9 can be supported by the driving wheel 2 and the driven wheel 3. The yielding assembly 6 is used to control the relative connecting plates 32 to move closer to or farther from each other, so that the winding drum 9 can pass between the relative driven wheels 3. The lifting control assembly 7 is used to control the lifting platform 4 to move up and down, so that the winding drum 9 placed on the lifting platform 4 can move above the driving wheel 2 and the driven wheel 3, and be supported by the driving wheel 2 and the driven wheel 3 when they are close to each other; A tension balancing mechanism 8 is also provided on the bottom plate 1 , and the tension balancing mechanism 8 is used to control the tension of the wire released from the winding drum 9 .

[0023] As can be seen from the above, the wire-releasing device, by setting a yielding component 6, is convenient for controlling the relative driven wheels 3 to approach and move away from each other, so that when the winding drum 9 is replaced, the winding drum 9 can pass between the relative driven wheels 3 and move to the lifting platform 4. By setting a lifting control component 7, it is convenient to lift the winding drum 9 on the lifting platform 4, and in conjunction with the setting of the clamping component 5, it is possible to control the driving wheel 2 and the driven wheel 3 to approach and move away from each other, so that the winding drum 9 lifted by the lifting platform 4 can be quickly and conveniently erected on the driving wheel 2 and the driven wheel 3, and the rotation of the driving wheel 2 drives the winding drum 9 to rotate and release the wire, thereby facilitating the control of the wire-releasing speed of the winding drum 9.

[0024] When the device is used, the relative driven wheels 3 are controlled to move away from each other by the yielding component 6, so that the winding drum 9 can roll from one side of the base plate 1 to the base plate 1 and the lifting platform 4; the lifting control component 7 is used to control the lifting platform 4 to lift the winding drum 9, so that the upper part of the winding drum 9 exceeds the height of the driving wheel 2 and the driven wheel 3; the clamping component 5 is used to control the driving wheel 2 and the driven wheel 3 to approach each other, so that the distance between the driving wheel 2 and the driven wheel 3 is smaller than the diameter of the winding drum 9; the relative driven wheels 3 are controlled to approach each other by the yielding component 6, so that the connecting plate 32 contacts the side of the winding drum 9; the lifting control component 7 is used to control the lifting platform 4 to descend, so that the driven wheel 3 is mounted on the driving wheel 2 and the driven wheel 3, and then the wire on the winding drum 9 is pulled to the processing equipment after passing through the tension balancing mechanism 8.

[0025] Embodiment 2 like Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 9 and Figure 10 As shown, the difference between this embodiment and the above embodiment is that the clamping assembly 5 includes a guide rail 51, a slider 52, a screw rod 53 and a clamping control motor 54. The guide rail 51 is fixedly mounted on the base plate 1 in a rectangular array, the slider 52 is slidably mounted on the guide rail 51, the rear bracket 21 and the front bracket 31 are respectively fixedly mounted on the guide rails 51 on both sides, the two ends of the screw rod 53 are respectively rotatably connected to the guide rails 51 on both sides, and the two sides of the screw rod 53 are provided with threads with opposite rotation directions, the opposing sliders 52 are respectively threadedly connected to the two sides of the screw rod 53, the clamping control motor 54 is fixedly mounted on the base plate 1, and the driving end of the clamping control motor 54 is connected to one of the screw rods 53 through a transmission pulley.

[0026] As can be seen from the above, since the slider 52 is slidably installed on the guide rail 51, the screw rod 53 is rotationally connected to the guide rail 51 and is threadedly connected to the slider 52. When the screw rod 53 rotates, since the sliders 52 on both sides have a threaded connection relationship with the threads on the screw rod 53 that rotate in opposite directions, the slider 52 moves in the opposite direction, thereby driving the rear bracket 21 and the front bracket 31 to move closer to or away from each other.

[0027] The clamping assembly 5 also includes a transmission short shaft 55, which is rotatably mounted on the lower surface of the base plate 1. The base plate 1 is provided with a connecting hole 11 that passes through its upper and lower surfaces. The transmission short shaft 55 is connected to the screw rod 53 through a transmission pulley, and the transmission short shafts 55 are connected to each other through a transmission pulley.

[0028] As can be seen from the above, by setting the transmission short shaft 55, the transmission belt connecting the two screw rods 53 is set below the base plate 1 instead of above the base plate 1, thereby preventing the winding drum 9 from colliding with the transmission belt linking the two screw rods 53 when moving on the base plate 1, and by setting the connecting hole 11, the transmission short shaft 55 and the screw rod 53 can be transmitted.

[0029] A driving motor 22 is fixedly mounted on one of the rear brackets 21 , and a driving end of the driving motor 22 is connected to the driving wheel 2 via a driving pulley.

[0030] As can be seen from the above, by installing the driving motor 22 on one of the rear brackets 21 , the rotation of the driving wheel 2 can be stably controlled.

[0031] The yield assembly 6 includes a screw rod 61, a guide rod 62, an internal threaded tube 63 and a limit plate 64. The screw rod 61 and the guide rod 62 are both rotatably connected to the front bracket 31, and the screw rod 61 and the guide rod 62 are both fixedly connected to the connecting plate 32. An upper mounting plate 311 is fixedly mounted on the front bracket 31. The internal threaded tube 63 is rotatably mounted on the upper mounting plate 311, and the internal threaded tube 63 is threadedly connected to the screw rod 61. The limit plate 64 is fixedly connected to the screw rod 61 and the guide rod 62.

[0032] As can be seen from the above, since the screw 61 and the guide rod 62 are fixedly connected to the connecting plate 32, and the screw 61 and the guide rod 62 are connected to the front bracket 31, the connecting plate 32 and the front bracket 31 are slidingly arranged, and the screw 61 cannot rotate. Since the internal threaded tube 63 is rotatably connected to the front bracket 31 through the upper mounting plate 311, when the internal threaded tube 63 rotates, it can drive the screw 61 threadedly connected thereto to move linearly, thereby achieving the effect of controlling the distance between the connecting plate 32 and the front bracket 31.

[0033] A sliding hole 12 is provided on the base plate 1, and a lower mounting plate 312 is fixedly mounted on the front bracket 31. The lower mounting plate 312 passes through the sliding hole 12 and extends to the bottom of the base plate 1. The yielding assembly 6 also includes a transmission long shaft 65 and a yielding control motor 66. The two ends of the transmission long shaft 65 are respectively rotatably connected to the lower mounting plate 312. The yielding control motor 66 is fixedly mounted on one of the front brackets 31. The driving end of the yielding control motor 66 is transmission-connected to one of the internal threaded tubes 63, and the driving end of the yielding control motor 66 is transmission-connected to one end of the transmission long shaft 65, and the other internal threaded tube 63 is transmission-connected to the other end of the transmission long shaft 65.

[0034] As can be seen from the above, since the yield control motor 66 is installed on one of the front brackets 31, the yield control motor 66 is carried to move when the front bracket 31 moves. Since the transmission long shaft 65 is rotatably connected to the front bracket 31 through the lower mounting plate 312, the front bracket 31 moves with the transmission long shaft 65. Therefore, the transmission long shaft 65 and the yield control motor 66 cannot be displaced relative to the front bracket 31. Since the two ends of the transmission long shaft 65 are respectively connected to the driving end of the yield control motor 66 and the other internal threaded tube 63 for transmission, the yield control motor 66 can drive the internal threaded tube 63 on the same side that is directly connected to it for transmission to rotate, and can also drive the internal threaded tube 63 on the other side to rotate synchronously.

[0035] Embodiment 3 like Figure 1 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the difference between this embodiment and the above embodiment is that the lifting control component 7 includes a threaded vertical rod 71, a lifting control motor 72 and a nut 73. The threaded vertical rod 71 is rotatably installed on the base plate 1 in a rectangular array, and the lower end of the threaded vertical rod 71 passes through the base plate 1 and extends to the bottom of the base plate 1. The lower ends of all the threaded vertical rods 71 ​​are synchronously driven, the lifting control motor 72 is fixedly installed on the base plate 1, and the driving end of the lifting control motor 72 is transmission-connected to one of the threaded vertical rods 71. The nut 73 is fixedly installed on the lifting platform 4, and the nut 73 is threadedly connected to the threaded vertical rod 71.

[0036] As can be seen from the above, since all the threaded vertical rods 71 ​​are synchronously driven by the transmission pulley, all the threaded vertical rods 71 ​​have the same rotation speed. Since the threaded vertical rods 71 ​​are threadedly connected to the nuts 73 fixed on the lifting platform 4, when the threaded vertical rods 71 ​​rotate, the lifting platform 4 is driven to move up and down.

[0037] A through opening 41 is provided in the middle of the lifting platform 4, and a fixed shaft 42 is symmetrically fixed between the two ends of the through opening 41. Support wheels 43 are sleeved on both sides of the fixed shaft 42, and the support wheels 43 can slide and rotate on the fixed shaft 42. A positioning block 44 is also rotatably installed in the middle of the fixed shaft 42, and a spring 45 is fixedly installed between the positioning block 44 and the support wheel 43. The top of the support wheel 43 is highly aligned with the upper surface of the lifting platform 4. A notch 13 is provided on the bottom plate 1, and the support wheel 43 is arranged on the inner side of the notch 13.

[0038] As can be seen from the above, by providing the through opening 41, the fixed shaft 42 and the supporting wheel 43, the winding drum 9 can be limited in the middle of the driving wheel 2 and the driven wheel 3 when it moves between the supporting wheels 43. When the winding drum 9 rises to a suitable height, it can be simultaneously contacted by the driving wheel 2 and the driven wheel 3 that are close to each other, so that the winding drum 9 will not fall or collide when the lifting platform 4 descends and separates from the winding drum 9. At the same time, by providing the positioning block 44 and the spring 45, the supporting wheel 43 is spaced from the side wall of the through opening 41 when not affected by external force, so that when the driven wheels 3 are close to each other, the connecting plates 32 on both sides push the winding drum 9 to move horizontally, so that the two ends of the winding drum 9 are respectively contacted and clamped with the connecting plates 32 on both sides. In this embodiment, the side wall of the connecting plate 32 close to the winding drum 9 can be set to a smooth plane or a ball bearing can be installed on the surface, so as to prevent the winding drum 9 from undergoing a large axial displacement of a long length during rotation while avoiding the generation of large resistance, so that the winding drum 9 will not undergo axial displacement during the rolling and unwinding process.

[0039] Embodiment 4 like Figure 11 As shown, the difference between this embodiment and the above embodiment is that the tension balancing mechanism 8 includes a support frame 81, a fixed pulley 82, a guide wheel 83 and a movable pulley 84, the fixed pulley 82 and the guide wheel 83 are both rotatably mounted on the support frame 81, and the movable pulley 84 is vertically slidably mounted on the support frame 81.

[0040] As can be seen from the above, when the pay-off device is used, the wire extending from the winding drum 9 is passed around the fixed pulley 82 and then around the movable pulley 84, and then the pay-off device is extended from the guide wheel 83, and the wire can be wound multiple times between the fixed pulley 82 and the movable pulley 84 as needed.

[0041] Embodiment 5 See also Figure 1 - Figure 11 The present invention also discloses a wire laying method for precious metal wire processing, the specific steps of which are: The relative driven wheels 3 are controlled to move away from each other by the letting assembly 6, so that the winding drum 9 can roll from one side of the bottom plate 1 to the bottom plate 1 and the lifting platform 4; The lifting platform 4 is controlled by the lifting control component 7 to lift the winding drum 9 so that the upper part of the winding drum 9 exceeds the height of the driving wheel 2 and the driven wheel 3; The driving wheel 2 and the driven wheel 3 are controlled to approach each other by the clamping assembly 5, so that the distance between the driving wheel 2 and the driven wheel 3 is smaller than the diameter of the winding drum 9; The relative driven wheels 3 are controlled to approach each other by the letting assembly 6, so that the connecting plate 32 contacts the side of the winding drum 9; The lifting platform 4 is controlled to descend by the lifting control assembly 7 so that the driven wheel 3 is mounted on the driving wheel 2 and the driven wheel 3 , and then the wire on the winding drum 9 is pulled to the processing equipment through the tension balance mechanism 8 .

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
