[0045] Figure 1 The figure shows a schematic diagram of the structure of a wire scraping device in an embodiment of the present invention. For the convenience of description, the figure only shows the structure related to the embodiment of the present invention.

[0046] Referring to the drawings, an embodiment of the present invention provides a wire scraping device 100 including a base 10, a pressing assembly 20 and a wire scraping assembly 30. The wire scraping device 100 of the present application is applied to a yarn casting robot, and in other embodiments, it can also be applied to other devices suitable for the wire scraping device 100, which is not limited here.

[0047] The base 10 has a scraping station for scraping the bobbin, and the bobbin can be positioned at the scraping station. The pressing assembly 20 includes a bracket 21, a clamping mechanism 22, a rotating mechanism 23 and a clamping member 24. The bracket 21 is fixed on the base 10, the clamping mechanism 22 is installed on the bracket 21, the rotating mechanism 23 is arranged on the clamping mechanism 22, and the clamping member 24 is connected to the rotating mechanism 23. The clamping mechanism 22 is used to provide a clamping force for the clamping member 24 to clamp the bobbin in a direction perpendicular to the base 10, and the rotating mechanism 23 is used to provide a driving force for the clamping member 24 to rotate around an axis. Specifically, one end of the bobbin in the axial direction is positioned at the base 10, and the clamping member 24 is axially clamped on the end of the bobbin away from the base 10.

[0048] In the embodiment of the present application, the center of the pressing member 24 coincides with the central axis of the cop, and the pressing member 24 can rotate around its own axis under the driving force of the rotating mechanism 23, thereby driving the cop to rotate around its own axis.

[0049] The wire scraping assembly 30 is located on one side of the pressing assembly 20, and includes a first mounting seat 31 and a scraper 32 arranged on the first mounting seat 31. The first mounting seat 31 is fixed to the base 10, and the scraper 32 can contact the surface of the tube yarn to scrape the wire when the tube yarn is located at the wire scraping station.

[0050] Thus, through the pressing force provided by the pressing mechanism 23, the pressing member 24 presses the cheese on the base 10. Since the pressing member 24 can rotate driven by the rotating mechanism 23, the cheese can rotate driven by the pressing member 24. At this time, by bringing the scraping blade 32 into contact with the surface of the rotating cheese, the thread ends on the surface of the cheese can be quickly integrated into an easily accessible position. In the wire scraping device 100 of the present application, the pressing mechanism 23, the rotating mechanism 23 and the scraping blade 32 have a simple structure and are compact, and the overall occupied space is small.

[0051] In some embodiments, the base 10 includes a support platform 11, a track assembly 12 and a moving unit. The track assembly 12 is provided on the support platform 11. The track assembly 12 has tracks, and the moving unit is slidably connected to the tracks. The cheese is positioned on the moving unit, wherein the tracks have a wire scraping station. Specifically, positioning posts are provided on the moving unit, and the cheese is sleeved on the positioning posts. Further, the bracket 21 of the pressing-down assembly 20 is fixed to the support platform 11, and the wire scraping assembly 30 is fixed to the track assembly 12. In some embodiments, the tracks may also have other stations, which are not limited herein. Thus, the space on the track assembly 12 can be fully utilized, making the structure of the wire scraping device 100 more compact.

[0052] In some embodiments, the wire scraping assembly 30 further includes a first driving member 33 provided on the first mounting seat 31. The first driving member 33 is located on one side of the scraping blade 32, and the first driving member 33 is used to drive the scraping blade 32 to move in a direction close to or away from the cheese. Thus, when the cheese is at the wire scraping station, the first driving member 33 can be used to drive the scraping blade 32 close to the cheese for wire scraping operation. At the same time, when the wire scraping operation is completed, the first driving member 33 can be used to drive the scraping blade 32 away from the cheese and retract to the initial position, thereby avoiding misoperation of the cheese before and after wire scraping and affecting the wire scraping quality.

[0053] In some embodiments, the wire scraping assembly 30 further includes a second driving member provided on the first mounting seat 31. The second driving member is located on one side of the scraping blade 32, and the second driving member is used to drive the scraping blade 32 to move along the axial direction of the cheese. Thus, during the wire scraping process, the wire scraping can be performed along the axial direction of the cheese so that the thread ends can be integrated into an easily accessible position at the next station. In other embodiments, the position of the scraping blade 32 can also be fixed so that the wire scraping position of the cheese is fixed, and this wire scraping position is the position where the thread ends are easily accessible at the next station.

[0054] In some embodiments, the wire scraping assembly 30 further includes a first rotating shaft 34 and a first transmission mechanism 35. The first rotating shaft 34 is fixed to the first mounting seat 31. The first transmission mechanism 35 is rotatably connected to the first rotating shaft 34, and both ends of the first transmission mechanism 35 are respectively connected to the scraper 32 and the first driving member 33. The first driving member 33 drives the scraper 32 to swing around the first rotating shaft 34 through the first transmission mechanism 35. The method of driving the first transmission mechanism 35 by the first driving member 33 to make the scraper 32 swing is simpler, and the structure is more compact, occupying less space.

[0055] Further, the first transmission mechanism 35 includes a first link mechanism. The first link mechanism includes a first link 351 and a second link 352. The first link 351 extends along the longitudinal direction of the first mounting seat 31. The first driving member 33 is used to drive the first link 351 to move along the longitudinal direction of the first mounting seat 31. One end of the second link 352 is rotatably connected to the first link 351, and the other end of the second link 352 is connected to one end of the scraper 32. The first rotating shaft 34 is located on one side of the second link 352 along the width direction of the first mounting seat 31, and the second link 352 is rotatably connected to the first rotating shaft 34. In this way, the transmission method through the first link 351 and the second link 352 is simple, and the positional relationship among the first link 351, the second link 352 and the first rotating shaft 34 makes the structure of the first transmission mechanism 35 compact.

[0056] Furthermore, there are multiple scrapers 32 and multiple second links 352. Each scraper 32 is connected to a corresponding second link 352. The multiple second links 352 are arranged at intervals along the longitudinal direction of the first link 351. Among them, each scraper 32 can contact the surface of a corresponding yarn tube located at the wire scraping station to perform wire scraping. In this way, multiple yarn tubes can be wire-scraped simultaneously, and the multiple scrapers 32 can share the same first link 351 and the same first driving member 33, making the wire scraping assembly 30 more compact in structure and occupying less space.

[0057] Specifically, in one embodiment, the first driving member 33 includes a first driving cylinder and a first telescopic rod. The first driving member 33 is placed along the longitudinal direction of the first mounting seat 31 and is located on one side of the first link 351 along the width direction of the first mounting seat 31. The first link 351 includes a link body and a first connecting portion protruding from the link body along the width direction of the first mounting seat 31. One end of the first telescopic rod is connected to the first connecting portion. In another embodiment, the first driving member 33 can also be located on one side of the first link 351 along the height direction of the first mounting seat 31. The first link 351 includes a link body and a second connecting portion protruding from the link body along the height direction of the first mounting seat 31. One end of the first telescopic rod is connected to the second connecting portion, which is not limited herein.

[0058] In some embodiments, the squeegee 32 includes a squeegee body 321 and a connecting member 322. One end of the connecting member 322 is connected to the squeegee body 321, and the other end of the connecting member 322 is connected to the second connecting rod 352. There is an included angle between the connecting member 322 and the second connecting rod 352. In this way, the swing angle of the squeegee 32 can be further reduced, saving the swing space and reducing the occupied space of the overall structure.

[0059] In some embodiments, the pressing mechanism 22 includes a second driving member 221, a hinge seat 222, a second connecting rod mechanism 223, and a second mounting seat 224. The second driving member 221 and the hinge seat 222 are both provided on the bracket 21. The second connecting rod mechanism 223 is hinged to the hinge seat 222, and both ends of the second connecting rod mechanism 223 are respectively hinged to the second driving member 221 and the second mounting seat 224. The rotating mechanism 23 is provided on the second mounting seat 224. The second driving member 221 drives the second mounting seat 224 to move in a direction perpendicular to the base 10 through the second connecting rod mechanism 223. In this way, when it is necessary to press the cheese, the second driving member 221 drives the second connecting rod mechanism 223 to rotate around the hinge seat 222, and the second mounting seat 224 can swing with the second connecting rod mechanism 223 to move in a direction perpendicular to the base 10. When it is not necessary to press the cheese, the second driving member 221 drives the second connecting rod mechanism 223 to rotate around the hinge seat 222, and the second mounting seat 224 can swing with the second connecting rod mechanism 223 to move in a direction away from the base 10. The method of driving the second connecting rod mechanism 223 by the second driving member 221 to make the second mounting seat 224 swing is simpler, and the space in both the vertical and horizontal directions is fully utilized, with better space utilization rate.

[0060] Further, the second connecting rod mechanism 223 includes two third connecting rods 2231 and a connecting rod. The two third connecting rods 2231 are arranged at intervals and in parallel in the first direction. The connecting rod is located between the two third connecting rods 2231. Both ends of the connecting rod are respectively connected to one end of the two third connecting rods 2231. The second driving member 221 is connected to the connecting rod. The other ends of the two third connecting rods 2231 are respectively hinged to both sides of the second mounting seat 224. The two third connecting rods 2231 are respectively hinged to both sides of the hinge seat 222. In this way, by connecting the two third connecting rods 2231 to the hinge seat 222 and the second mounting seat 224, the movement of the second mounting seat 224 is made more stable, so that the pressing force pressing on the cheese by the pressing member 24 is more reliable.

[0061] Further, the second link mechanism 223 further includes two fourth links 2232. The two fourth links 2232 are arranged at intervals and in parallel along the first direction. The two third links 2231 and the two fourth links 2232 are arranged at intervals and in parallel along a second direction intersecting the first direction. One ends of the two fourth links 2232 are respectively hinged to both sides of the hinge seat 222, and the other ends of the two fourth links 2232 are respectively rotatably connected to both sides of the second mounting seat 224. In this way, the connection between the hinge seat 222 and the second mounting seat 224 is made more reliable, and further improves the movement reliability and smoothness of the second mounting seat 224.

[0062] Specifically, in an embodiment, the third link 2231 includes a first section and a second section. One end of the first section is connected to one end of the second section at the hinge seat 222. The other end of the first section is connected to the connecting rod, and the other end of the second section is rotatably connected to the second mounting seat 224. In this way, the acting force exerted by the second driving member 221 on the third link 2231 through the connecting rod is better, and the pressing force of the pressing member 24 on the yarn package is more sufficient.

[0063] Specifically, in an embodiment, the second driving member 221 includes a second driving cylinder 2211 and a second telescopic rod 2212. A collar 2213 is provided at the end of the second telescopic rod 2212. The collar 2213 is sleeved on the connecting rod. The pressing mechanism 22 further includes two limiting sleeves 225. The two limiting sleeves 225 are both sleeved on the connecting rod and are located on both sides of the collar 2213. Both ends of each limiting sleeve 225 are respectively abutted against the collar 2213 and a corresponding third link 2231 to limit the axial movement of the collar 2213 along the connecting rod. In this way, when the second telescopic rod 2213 makes a telescopic movement, the third link 2231 can be rotated around the hinge seat 222 by pushing the connecting rod 2231.

[0064] In some embodiments, the rotating mechanism 23 includes a third driving member 231 and a third transmission mechanism 232 provided on the pressing mechanism 22. Both ends of the third transmission mechanism 232 are respectively connected to the third driving member 231 and the pressing member 24. The third driving member 231 drives the pressing member 24 to rotate through the third transmission mechanism 232. Specifically, the third driving member 231 and the third transmission mechanism 232 are both mounted on the second mounting seat 224.

[0065] Further, there are multiple pressing members 24. The third transmission mechanism 232 includes multiple pulleys and multiple belts. The third driving member 231 is used to drive one of the pulleys to rotate. At least one belt is used to connect adjacent two pulleys in a transmission manner. Each pressing member 24 is connected to a corresponding pulley. Among them, each pressing member 24 can press a corresponding yarn tube located at the wire scraping station. In this way, multiple yarn tubes can be pressed simultaneously, and the same third transmission mechanism 232 and the third driving member 231 can be shared among multiple pressing members 24, making the pressing assembly 20 more compact in structure and occupying less space.

[0066] In other embodiments, the third transmission mechanism 232 may also include multiple sprockets and multiple chains. The third driving member 231 is used to drive one of the sprockets to rotate. At least one chain is used to connect adjacent two sprockets in a transmission manner. Each pressing member 24 is connected to a corresponding sprocket.

[0067] Based on the same inventive concept, the present application also provides a yarn feeding robot for feeding yarn tubes. The yarn feeding robot includes the above-mentioned wire scraping device 100.

[0068] Specifically, the yarn feeding robot further includes a blanking guiding device, a thread head obtaining device, and a feeding device.

[0069] More specifically, the blanking guiding device is used to guide the yarn tube to the moving unit for blanking. After the wire scraping device 100 performs a wire scraping operation on the surface of the yarn tube to find the thread head of the yarn tube, the thread head obtaining device is used to obtain the thread head of the yarn tube, and the feeding device is used to grab the yarn tube for feeding, such as feeding it into the yarn storage of a winding machine.

[0070] The wire scraping device 100 and the yarn feeding robot provided by the embodiments of the present invention have the following beneficial effects compared with the prior art:

[0071] Through the pressing force provided by the pressing mechanism 23, the pressing member 24 presses the yarn tube on the base 10. And since the pressing member 24 can rotate driven by the rotating mechanism 23, the yarn tube can rotate driven by the pressing member 24. At this time, when the blade 32 is in contact with the surface of the rotating yarn tube, the thread head can be quickly integrated into an easily found position. For the wire scraping device 100 and the yarn feeding robot of the present application, the pressing mechanism 23, the rotating mechanism 23, and the blade have simple structures and are compact, and the overall occupied space is small.

[0072] The technical features of the above-mentioned embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0073] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
