[0061] A luggage trolley is a component used to drag travel luggage. It often has a telescopic function and is lightweight and sturdy.

[0062] The luggage rod grinding device used in the luggage production in the related art usually uses a hard grinding piece to grind the luggage rod. However, in order to ensure its light weight, the luggage rod needs to be made into a hollow structure. When it encounters a hard grinding piece, it is easy to deform and cannot be used.

[0063] Based on this, in order to improve the problem in the related art that luggage pull rods are easily deformed due to grinding with hard grinding parts, the embodiments of the present application provide the following solution.

[0064] Please also read Figure 1 and Figure 2 The embodiment of the present application provides a pull rod polishing device 100 for luggage production, the pull rod polishing device 100 for luggage production includes a substrate 10, a flexible polishing mechanism 20, a feeding mechanism 30 and a controller 40, wherein the flexible polishing mechanism 20 is arranged on the substrate 10, and the flexible polishing mechanism 20 includes a flexible polishing piece 201, the flexible polishing piece 201 is used to polish the outer circumferential surface of the luggage pull rod 50, and can be deformed when contacting the luggage pull rod 50; the feeding mechanism 30 is arranged on the substrate 10, and is used to clamp and rotate the luggage pull rod 50 while pushing the luggage pull rod 50 toward the flexible polishing piece 201; the controller 40 is electrically connected to the flexible polishing mechanism 20 and the feeding structure respectively, and the controller 40 is used to control the amplitude of the feeding mechanism 30 pushing the luggage pull rod 50 toward the flexible polishing piece 201 according to the deformation amplitude of the flexible polishing piece 201.

[0065] It can be understood that the substrate 10 is a component used to carry other structures of the luggage production pull rod grinding device 100; the flexible grinding mechanism 20 is a mechanism for grinding the outer surface of the luggage pull rod 50, and the flexible grinding member 201 is a grinding tool that can deform when it contacts the luggage pull rod 50, for example, it can be a soft belt with abrasive particles adhered to it, or it can be sandpaper, but it is not limited to this. The luggage pull rod 50 is a hollow cylindrical rod body, or a rod body with at least one rotating surface. The outer surface of the luggage pull rod 50 needs to be polished to avoid scratching the user during use or causing jamming during the extension and retraction process. The controller 40 is a device that can receive, process information and issue instructions, for example, it can include an MCU, a data processing chip, etc., but it is not limited to this. The deformation amplitude of the flexible polishing member 201 refers to the degree of deformation of the flexible polishing member 201 after contacting the luggage pull rod 50. When the feeding mechanism 30 gradually pushes the luggage pull rod 50 toward the flexible polishing member 201, the deformation amplitude of the flexible polishing member 201 gradually increases under the action of the feeding mechanism 30 and the luggage pull rod 50. The amplitude by which the feeding mechanism 30 pushes the luggage pull rod 50 toward the flexible polishing member 201 can represent the distance by which the feeding mechanism 30 pushes the luggage pull rod 50 toward the flexible polishing member 201.

[0066] From the above, it can be seen that the luggage rod polishing device 100 for luggage production provided in the embodiment of the present application integrates the flexible polishing mechanism 20, the feeding mechanism 30 and the controller 40 on the substrate 10, and the luggage rod 50 is clamped and rotated by the feeding mechanism 30 while being pushed toward the flexible polishing part 201 on the flexible polishing mechanism 20. The controller 40 controls the amplitude of the feeding mechanism 30 to push the luggage rod 50 toward the flexible polishing part 201 according to the deformation amplitude of the flexible polishing part 201, so as to achieve uniform polishing of the outer surface of the luggage rod 50. In this way, the luggage rod 50 is polished using a deformable flexible polishing piece 201, and the force applied by the feeding mechanism 30 to the luggage rod 50 can be changed according to the deformation amplitude of the flexible polishing piece 201, so that the force applied to the luggage rod 50 will not exceed the range it can bear, and the luggage rod 50 is not easy to deform during the polishing process. This can not only ensure that the polishing is uniform and smooth, but also avoid the luggage rod 50 from being damaged due to uneven force during the polishing process, thereby reducing the damage rate of the workpiece, thereby reducing the production cost and effectively improving the production efficiency.

[0067] In some embodiments, please refer to Figures 1 to 3 The flexible polishing mechanism 20 further includes a flexible polishing member bracket 202, one end of which is disposed on the substrate 10. One end of the flexible polishing member 201 is connected to the flexible polishing member bracket 202, and the other end of the flexible polishing member 201 is connected to the substrate 10.

[0068] It can be understood that the flexible polishing member bracket 202 is used to support the flexible polishing member 201, and can be a long rod standing on the base plate 10, or a cantilever beam extending from the wall, but is not limited thereto.

[0069] In this way, the flexible polishing piece 201 is hung up, and then the luggage pull rod 50 is pushed toward the flexible polishing piece 201 for polishing by the feeding mechanism 30. The flexible polishing piece 201 is hung up to provide a larger space for the flexible polishing piece 201 to deform, so that the flexible polishing mechanism 20 can process larger workpieces and can withstand the greater force applied by the feeding mechanism 30, thereby expanding the use scenarios of the flexible polishing mechanism 20, increasing the adaptability of the flexible polishing mechanism 20, and at the same time extending the service life of the flexible polishing mechanism 20, and reducing the cost required for maintenance and replacement of equipment.

[0070] Optionally, in some embodiments, see Figure 1 and Figure 2 The flexible polishing mechanism 20 further includes a vibration generator 203 , which is disposed on the flexible polishing piece bracket 202 and is used to vibrate the flexible polishing piece bracket 202 to clean the flexible polishing piece 201 .

[0071] It can be understood that the vibration generator 203 is a device for generating vibration on the flexible grinding piece support 202 .

[0072] In this way, by arranging a vibration generator 203 on the flexible polishing piece bracket 202, when debris adheres to the flexible polishing piece 201 due to polishing the workpiece, the debris on the flexible polishing piece 201 can be shaken off by starting the vibration generator 203, thereby realizing the function of cleaning the flexible polishing piece 201. By timely cleaning the flexible polishing piece 201, the polishing work efficiency can be improved, and the polishing quality can be guaranteed. The overheating of the workpiece and the flexible polishing piece 201 during the polishing process due to the debris adhering to the flexible polishing piece 201 is effectively avoided, the frequency of maintenance and replacement of the flexible polishing piece 201 is reduced, and the cost required for maintenance equipment is reduced.

[0073] Optionally, in some embodiments, see Figures 1 to 3 The flexible polishing piece 201 includes a polishing belt 2011, a first elastic belt 2012 and a second elastic belt 2013, wherein the polishing belt 2011 is used to polish the outer circumference of the luggage pull rod 50; one end of the first elastic belt 2012 is connected to the flexible polishing piece bracket 202, and the other end of the first elastic belt 2012 is connected to the polishing belt 2011; one end of the second elastic belt 2013 is connected to the substrate 10, and the other end of the second elastic belt 2013 is connected to the polishing belt 2011.

[0074] It is understood that the grinding belt 2011 can be a soft belt with abrasive particles attached thereto, or sandpaper, but is not limited thereto. The first elastic belt 2012 and the second elastic belt 2013 are elastic and retractable components, and can be springs or rubber bands, but are not limited thereto.

[0075] In this way, the polishing belt 2011 is pulled onto the flexible polishing piece bracket 202 and the base through the first elastic belt 2012 and the second elastic belt 2013. After the polishing belt 2011 contacts the luggage pull rod 50, the flexible polishing piece 201 is deformed through the first elastic belt 2012 and the second elastic belt 2013, so that the flexible polishing piece 201 can better fit the polished luggage pull rod 50 and can adapt to luggage pull rods 50 of different sizes. The first elastic belt 2012 and the second elastic belt 2013 buffer the polishing belt 2011, so that the reaction force on the luggage pull rod 50 does not exceed the range it can bear, and it is not easy to deform during the polishing process. In this way, it can ensure that the polishing is uniform and smooth, and the luggage pull rod 50 can be prevented from being damaged due to uneven force during the polishing process, thereby reducing the damage rate of the workpiece, thereby reducing the cost required for production, and effectively improving the production efficiency.

[0076] Optionally, see Figures 1 to 3 The flexible polishing mechanism 20 also includes a tension sensor 204, which is arranged at the connection between the flexible polishing piece bracket 202 and the first elastic band 2012, and the tension sensor 204 is electrically connected to the controller 40, and the tension sensor 204 is used to detect the magnitude of the tension applied to the flexible polishing piece 201; wherein the controller 40 is used to control the feeding mechanism 30 to push the luggage pull rod 50 toward the flexible polishing piece 201 according to the tension signal detected by the tension sensor 204.

[0077] With such a configuration, the controller 40 can control the feeding mechanism 30 according to the tension signal detected by the tension sensor 204. A tension value can be preset by the controller 40. When the tension signal detected by the tension sensor 204 is greater than the preset value, the amplitude of the feeding mechanism 30 pushing the luggage rod 50 toward the flexible polishing member 201 is reduced. When the tension signal detected by the tension sensor 204 is less than the preset value, the amplitude of the feeding mechanism 30 pushing the luggage rod 50 toward the flexible polishing member 201 is increased. In this way, luggage rods 50 of different shapes can be polished with uniform force, so that the surface of the luggage rod 50 is flat and smooth, and the luggage rod 50 will not be deformed due to uneven force during the polishing process, thereby reducing the production scrap rate, reducing the waste caused by improper polishing, reducing the time and resources consumed in repairing scrap parts, and improving production efficiency.

[0078] In some embodiments, see Figure 1 and Figure 3The loading mechanism 30 includes at least one base 301, at least one loading arm 302 and at least one first driving device, the base 301 is movably arranged on the substrate 10; the loading arms 302 are hinged to the base 301 one by one, and the loading arms 302 are used to clamp and rotate the luggage pull rod 50; the first driving device is arranged at the hinge between the loading arm 302 and the base 301, and is used to drive the loading arm 302 to rotate around the base 301, so that the loading arm 302 pushes the luggage pull rod 50 toward the flexible polishing piece 201, and the first driving device is connected to the controller 40; wherein the controller 40 is used to control the rotation of the first driving device according to the tension signal detected by the tension sensor 204, thereby controlling the rotation angle of the loading arm 302.

[0079] It is understandable that the loading arm 302 can clamp the luggage pull rod 50 and rotate the luggage pull rod 50 by providing a rotatable triangular chuck or two opposite rotating disks. The first driving device can be a servo motor or a stepping motor, but is not limited thereto.

[0080] In this configuration, the controller 40 sends a signal to control the rotation of the first driving device according to the tension signal of the tension sensor 204, and then controls the rotation angle of the feeding arm 302, that is, controls the amplitude of the feeding mechanism 30 pushing the luggage rod 50 toward the flexible polishing piece 201. The controller 40 controls and adjusts the feeding mechanism 30 in real time according to the tension signal of the tension sensor 204, and can accurately control the feeding arm 302 according to the shape and flatness of the outer surface of the luggage rod 50, so that the outer surface of the luggage rod 50 is polished evenly and flat, and is smoother and less prone to jamming during the extension and retraction process, and can adapt to more luggage rods 50 of different shapes and sizes. When the luggage rod 50 contacts the polishing piece, it will not collide violently to cause damage to the luggage rod 50 or the feeding mechanism 30, thereby reducing the cost required for maintenance and replacement of equipment.

[0081] Optionally, in some embodiments, there are two bases 301, and the two bases 301 are arranged at intervals along the axial direction of the luggage pull rod 50; there are two loading arms 302, and the two loading arms 302 are hinged to the bases 301 one by one; there are two first driving devices, and the two first driving devices are respectively arranged on the two bases 301, and the power output ends of the first driving devices are connected to the loading arms 302 one by one;

[0082] The loading mechanism 30 also includes an image acquisition device, which is arranged at one end of the loading arm close to the base 301 and is electrically connected to the controller 40; the image acquisition device is used to acquire an image of the luggage pull rod 50; wherein the controller 40 is used to control the two first driving devices respectively according to the image transmitted by the image acquisition device, thereby adjusting the relative angle between the luggage pull rod 50 and the flexible polishing member 201.

[0083] It is understood that the image acquisition device 304 can be a camera or an infrared sensor, but is not limited thereto. By arranging the image acquisition device 304 near the base 301 and facing one end of the luggage pull rod 50, the image acquisition device 304 can rotate with the loading arm 302 and is not blocked by other components, so that the overall structure of the luggage pull rod 50 can be fully and in real time observed. The shape of the luggage pull rod 50 is not always regular, and often has a certain taper, and the grinding angle needs to be changed to adapt to its shape and taper. The controller controls the image acquisition device 304 to acquire the appearance image of the luggage pull rod 50, and uses the shape recognition system to analyze the obtained appearance image; the shape recognition system obtains multiple shaft diameter data and length data of the luggage pull rod 50 through the appearance image, and obtains the shape information and taper data of the luggage pull rod 50 according to the multiple shaft diameter data and length data; the controller 40 controls the two first driving devices to rotate to different angles respectively according to the shape information and taper data of the luggage pull rod 50, thereby adjusting the relative angle between the central axis of the luggage pull rod 50 and the flexible polishing part 201.

[0084] With such a configuration, the controller 40 can control the two feeding arms 302 to push the luggage rod 50 toward the flexible polishing member 201 according to the shape of the luggage rod 50 detected by the image acquisition device 304, thereby changing the relative angle between the flexible polishing member 201 and the luggage rod 50, so that the outer surfaces of the luggage rod 50 at different angles are subjected to the same friction force, so that the conical surface of the luggage rod 50 can also be evenly polished, and after the polishing is completed, the feeding mechanism 30 can be controlled to automatically separate the luggage rod 50 from the flexible polishing member 201. The controller 40 controls the polishing angle of the luggage rod 50, and no manual operation is required. The controller 40 determines the polishing completion of the luggage rod 50, which can avoid errors caused by human factors, make the polishing process more accurate, and make the quality of the workpiece obtained by the process more uniform, which significantly improves the polishing work efficiency.

[0085] Optionally, the feeding mechanism 30 also includes a temperature sensor, which is electrically connected to the controller and is used to detect the surface temperature of the flexible polishing piece 201 and the luggage pull rod 50; the controller 40 controls the feeding mechanism 30 according to the surface temperature of the flexible polishing piece 201 and the luggage pull rod 50 detected by the temperature sensor, so that the flexible polishing piece 201 is in continuous contact or separation with the luggage pull rod 50.

[0086] With such a configuration, the controller 40 can separate the flexible polishing member 201 from the luggage pull rod 50 after the flexible polishing member 201 has been in contact with the luggage pull rod 50 for a certain period of time, and detect the surface temperature of the flexible polishing member 201 and the luggage pull rod 50 with a temperature sensor, and the controller 40 can determine whether to continue polishing according to the surface temperature of the flexible polishing member 201 and the luggage pull rod 50. In this way, it can be avoided that the temperature of the contact part between the flexible polishing member 201 and the luggage pull rod 50 is too high due to long-term polishing or too strong polishing force, which affects the polishing quality, effectively ensures the processing quality of the luggage pull rod 50, reduces the working hours delayed due to improper processing, reduces the cost caused by damage to the workpiece or equipment, and improves the working efficiency of polishing.

[0087] Optionally, in some embodiments, see Figures 1 to 3 The base plate 10 is provided with a slide groove 101 along the axial direction of the luggage pull rod 50, and the feeding mechanism 30 also includes a slide 303 and a linear drive device, wherein the slide 303 is slidably arranged in the slide groove 101, and the slide 303 is connected to the base 301; the linear drive device is used to drive the slide 303 to move in the slide groove 101.

[0088] It can be understood that the linear drive device may include a screw installed in the slide groove 101, a nut installed on the slide 303 and a motor for driving the screw to rotate, and the slide 303 moves in the slide groove 101 through the cooperation of the screw and the nut; it may also include a roller installed on the slide 303 and driven by a motor, and the slide 303 moves in the slide groove 101 through the motor driving the roller, but it is not limited to this.

[0089] In this configuration, the linear drive device drives the slide 303 to move in the slide groove 101 along the axial direction of the luggage tie rod 50, connects the base 301 with the slide 303, and then makes the feeding arm 302 move in the slide groove 101 along the axial direction of the luggage tie rod 50 with the base 301 and the slide 303, so as to clamp the luggage tie rod 50. Under the action of the linear drive device, the feeding mechanism 30 can automatically complete the clamping of the luggage tie rod 50, reduce the demand for manual labor, save manpower, and improve the efficiency of the polishing work.

[0090] Optionally, see Figures 1 to 3The loading arm 302 includes a swing arm 3021, a clamping mechanism 3022 and a second driving device, wherein one end of the swing arm 3021 is hinged to the base 301; the clamping mechanism 3022 is rotatably arranged at the other end of the swing arm 3021, and is used to clamp the luggage pull rod 50; the second driving device is arranged on the swing arm 3021, and the power output end of the second driving device is connected to the clamping mechanism 3022, and the second driving device is used to drive the clamping mechanism 3022 to rotate around the axial direction of the luggage pull rod 50. The first driving device is arranged at the hinge between the swing arm 3021 and the base 301, and the first driving device is used to drive the swing arm 3021 to rotate around the base 301.

[0091] It can be understood that the second driving mechanism is a mechanism for driving the clamping mechanism 3022 to rotate axially around the luggage pull rod 50, and may include a DC motor or an AC motor, but is not limited thereto.

[0092] In this arrangement, the swing arm 3021 is driven to rotate by the first driving device so that the swing arm 3021 rotates toward the polishing belt 2011, pushing the luggage pull rod 50 toward the polishing belt 2011, and at the same time, the second driving device is started to drive the clamping mechanism 3022 to rotate, so as to drive the luggage pull rod 50 to rotate, and polishing is performed through the rotation of the luggage pull rod 50 and contact with the polishing belt 2011. In this way, the luggage pull rod 50 can be evenly contacted with the polishing belt 2011, thereby improving the uniformity and flatness of polishing, and the rotation can improve the efficiency of polishing, avoid polishing the same part for a long time, enhance the heat dissipation effect, and ensure the quality of polishing. Using mechanical equipment for polishing can also reduce the intensity of manual labor and improve safety.

[0093] In some embodiments, see 3 and Figure 4 The clamping mechanism 3022 includes a clamping plate 30221 and a plurality of top fasteners 30222, wherein the clamping plate 30221 is arranged at the other end of the swing arm 3021; ​​a plurality of top fasteners 30222 are movably arranged on the clamping plate 30221, and one end of the top fastener 30222 away from the center of the clamping plate 30221 extends to the outside of the clamping plate 30221, and the end points of the plurality of top fasteners 30222 away from the center of the clamping plate 30221 can be on the same circle concentric with the clamping plate 30221; the end of the plurality of top fasteners 30222 away from the center of the clamping plate 30221 is abutted against the inner surface of the luggage pull rod 50, so that the luggage pull rod 50 is fixed on the clamping plate 30221.

[0094] It can be understood that the clamping disk 30221 is a disk body with a regular shape and central symmetry, so that the center of gravity of the clamping disk 30221 does not deviate during rotation and can maintain stable rotation. Its shape can be square or circular, but is not limited thereto. The clamping disk 30221 is provided with a plurality of through holes on its outer surface perpendicular to the radial direction of the luggage pull rod 50, and a plurality of top fasteners 30222 are arranged in each through hole in a one-to-one correspondence. The diameter of one end of the top fastener 30222 facing the center of the clamping disk 30221 is larger than the diameter of the through hole, so that the top fastener 30222 will not fall out of the clamping disk 30221 from the through hole. The end of the top fastener 30222 away from the center of the clamping plate 30221 is made of tough and deformable material, such as plastic, silicone and the like, and its end is a spherical surface, so that the end of the top fastener 30222 away from the center of the clamping plate 30221 can better fit the inner surface of the luggage pull rod 50, and a plurality of top fasteners 30222 abut against the inner surface of the luggage pull rod 50 to form a stable clamping of the luggage pull rod 50.

[0095] In this arrangement, the clamping mechanism 3022 abuts against the inner surface of the luggage draw rod 50 through a plurality of top fasteners 30222 movably arranged on the clamping plate 30221, so that the luggage draw rod 50 is fixed on the clamping mechanism 3022. The clamping mechanism 3022 arranged in this way can quickly and stably clamp the luggage draw rod 50, and can adapt to luggage draw rods 50 of different diameters and shapes, thereby improving the grinding work efficiency, reducing damage to workpieces or equipment caused by unstable clamping, and thereby reducing the cost of equipment maintenance, reducing the damage rate of workpieces, and reducing the production cost of luggage draw rods 50.

[0096] In some embodiments, see Figure 4 The clamping mechanism 3022 also includes a plurality of elastic members 30223, and the plurality of elastic members 30223 correspond one to one with the plurality of top fixing members 30222. The top fixing members 30222 are connected to the clamping plate 30221 through the elastic members 30223, so that the endpoints of the plurality of top fixing members 30222 away from the center of the clamping plate 30221 can be on circular surfaces of different radii, so that the luggage pull rods 50 with different inner diameters can be fixed on the clamping plate 30221.

[0097] It can be understood that the elastic member 30223 is a member used to push the top fixing member 30222 away from the center of the clamping plate 30221. The elastic member 30223 can be a spring or a rubber body with elasticity, but is not limited thereto.

[0098] With such a configuration, when clamping the luggage tie rod 50, the top fastener 30222 needs to be pressed toward the center of the clamping plate 30221. When the top fastener 30222 is inside the luggage tie rod 50, the elastic member 30223 pushes the top fastener 30222 toward the inner surface of the luggage tie rod 50, thereby fixing the luggage tie rod 50. In this way, the clamping mechanism 3022 can clamp and fix the luggage tie rod 50 simply, quickly, and stably, effectively improving the efficiency of grinding. When the luggage tie rod 50 is subjected to excessive force, the top fastener 30222 can be used to slide against the luggage tie rod 50 to buffer the force, further protecting the luggage tie rod 50 from deformation, significantly reducing the risk of deformation of the luggage tie rod 50 during grinding, reducing the damage rate of the workpiece, and reducing the production cost of the luggage tie rod 50.

[0099] The embodiment of the present application further provides a rod polishing process for luggage production, which is applicable to the rod polishing device 100 for luggage production used in the above embodiment. The rod polishing process for luggage production includes:

[0100] Controlling the feeding mechanism 30 to clamp the luggage pull rod 50 and rotate the luggage pull rod 50;

[0101] The feeding mechanism 30 is controlled to push the luggage rod 50 toward the flexible polishing member 201, so that the flexible polishing member 201 polishes the outer circumferential surface of the luggage rod 50; the flexible polishing member 201 can be deformed when contacting the luggage rod 50, and the controller 40 controls the feeding mechanism 30 to push the luggage rod 50 toward the flexible polishing member 201 according to the deformation amplitude of the flexible polishing member 201;

[0102] After the grinding is completed, the feeding mechanism 30 is controlled to stop rotating the luggage pull rod 50 and push the luggage pull rod 50 away from the flexible grinding member 201;

[0103] The loading mechanism 30 is controlled to lower the luggage pull rod 50 .

[0104] From the above, it can be seen that the luggage rod polishing process for luggage production provided in the embodiment of the present application can use the flexible polishing piece 201 to polish the luggage rod 50, and control the feeding mechanism 30 to clamp the luggage rod 50 through the controller 40, and make the luggage rod 50 rotate and contact the flexible polishing piece 201, and control the feeding mechanism 30 to push the luggage rod 50 toward the flexible polishing piece 201 according to the deformation amplitude of the flexible polishing piece 201, so as to protect the luggage rod 50 from deformation when polishing, and can polish the outer surface of the luggage rod 50 evenly and smoothly, which can not only avoid damage to the workpiece and cause losses, reduce production costs, but also improve the polishing work efficiency.

[0105] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
