[0046] The technical solutions of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0047] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0048] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0049] like Figures 1 to 3 As shown, this application provides a polishing disc cutting device for cutting polishing discs from a strip 22. The polishing disc cutting device includes a body 05, a winding box 06, a positioning member 16, and a laser cutter 23. The positioning member 16 is fixed to the body 05. The laser cutter 23, the positioning member 16, and the winding box 06 are arranged sequentially from top to bottom in a first direction. A cutting hole 25 is formed on the positioning member 16. A plurality of positioning holes 27 are provided in the length direction of the strip 22. The center of the positioning hole 27 is set in the axial direction of the cutting hole 25. The first direction is the axial direction of the positioning hole 27.
[0050] In this embodiment, the laser cutter 23 can be mounted on a bracket, the bottom of which can be fixed to the ground or to the main body 05.
[0051] The polishing disc cutting device provided in this application, when cutting polishing discs from the material strip 22, sets the material strip 22 on the positioning member 16 and aligns the center of a positioning hole 27 on the material strip 22 with the axial direction of the cutting hole 25. Then, the laser cutter 23 is activated to cut the polishing disc from the material strip 22 according to the size of the polishing disc. The polishing disc falls from the cutting hole 25 into the rewind box 06 under the action of gravity, completing the cutting of one polishing disc. This process is repeated to cut polishing discs one by one from the material strip 22. Compared with the prior art of cutting polishing discs using metal abrasives, this application uses a laser cutter 23 to cut polishing discs from the material strip 22, which does not cause wear on the metal abrasives and thus saves time. The use of a laser cutter 23 in this application avoids the use of metal molds for mold manufacturing and repair, thereby reducing production costs. Furthermore, in the prior art, when using metal molds to punch and cut polishing discs, the powder generated by the metal molds can come into contact with and contaminate the polishing discs, affecting the cutting accuracy and appearance quality of the product edges. This application avoids the powder generated when using metal molds, making the polishing discs less prone to contamination, ensuring high cutting accuracy, and guaranteeing both appearance and quality. At the same time, the cutting holes 25 on the positioning component 16 facilitate the positioning of the cutting position on the strip 22 during cutting, improving cutting accuracy, and allowing the cut polishing discs to fall from the cutting holes 25 into the winding box 06, ensuring a smooth connection between the cutting and product storage processes and improving production efficiency.
[0052] Optionally, the polishing disc cutting device provided in this application embodiment further includes a rotation drive 26, an unwinding roller 01, and a winding roller 09, all mounted on the body 05. The unwinding roller 01, the positioning member 16, and the winding roller 09 are arranged in a second direction. The rotation drive 26 is pulsatorically connected to the winding roller 09 or the unwinding roller 01, and the second direction is perpendicular to the first direction. Thus, the material strip 22 is wound around the unwinding roller 01, and the material for completing the polishing disc cutting is wound around the winding roller 09. The rotation drive 26 drives the winding roller 09 or the unwinding roller 01 to rotate, thereby moving the material strip 22 and the cutting position on the material strip 22. The rotation drive 26 can be a stepper motor or a servo motor, etc.
[0053] Optionally, the polishing disc cutting device provided in this application embodiment further includes an unwinding side roller group located between the unwinding roller 01 and the laser cutter 23 in the second direction. The unwinding side roller group is installed on the body 05. The unwinding side roller group includes a first positioning roller 18 and a second positioning roller 17 arranged parallel to each other. The axial direction of the first positioning roller 18 is perpendicular to both the first direction and the second direction. A first material passage gap is left between the first positioning roller 18 and the second positioning roller 17. At the first material passage gap, both the first positioning roller 18 and the second positioning roller 17 are tangent to the second direction. In the first direction, the first material passage gap is located closer to the laser cutter 23 than the positioning member 16. By setting the first positioning roller 18 and the second positioning roller 17, it is easier to straighten the material strip 22 passing through the first material passage gap in the second direction, thereby making the material strip 22 less prone to curling during the process of cutting the polishing disc from the material strip 22, and improving the cutting accuracy.
[0054] Optionally, the axis of the unwinding roller 01 in the first direction is located above the first positioning roller 18 and the second positioning roller 17. In this way, the top end of the strip unwinding roller 01 extends to the first material passage gap at a certain inclination, and then passes through the first material passage gap in the second direction. This keeps the strip 22 itself in a taut state, making it less likely for the strip 22 to curl when the laser cutter 23 cuts it, thereby improving the cutting accuracy. In this embodiment, the unwinding roller 01 is fixed to the body 05 by the first connecting rod 02.
[0055] Optionally, the unwinding side roller group further includes a first unwinding tension roller 03, a second unwinding tension roller 04, and a third unwinding tension roller 21 arranged sequentially in the second direction. The first unwinding tension roller 03, the second unwinding tension roller 04, and the third unwinding tension roller 21 are all located between the unwinding roller 01 and the first positioning roller 18, with the second unwinding tension roller 04 located below the first unwinding tension roller 03 and the third unwinding tension roller 21. Thus, as... Figure 1 As shown, after the material strip 22 is fed out from the unwinding roller 01, it passes over the first unwinding tension roller 03 from top to bottom, the second unwinding tension roller 04 from bottom to top, the third unwinding tension roller 21 from top to bottom, and then passes through the first material passage gap from the second direction. In this way, the tension of the material strip 22 is further improved, and the accuracy of cutting and polishing discs is improved.
[0056] Optionally, the unwinding side roller group further includes a fourth unwinding tension roller 20 and a fifth unwinding tension roller 19 arranged in the second direction. The fourth unwinding tension roller 20 and the fifth unwinding tension roller 19 are both located between the third unwinding tension roller 21 and the first positioning roller 18. The fourth unwinding tension roller 20 is arranged close to the third unwinding tension roller 21. In the first direction, the distance between the top end of the third unwinding tension roller 21 and the laser cutter 23, the distance between the top end of the fourth unwinding tension roller 20 and the laser cutter 23, the distance between the top end of the fifth unwinding tension roller 19 and the laser cutter 23, and the distance between the first material passage gap and the laser cutter 23 are the same. In this way, after the material strip 22 passes over the third unwinding tension roller 21 from top to bottom, it passes over the fourth unwinding tension roller 20 from bottom to top, and then passes over the fifth unwinding tension roller 19 from top to bottom. After that, it is fed into the first material passage gap. The top of the fifth unwinding tension roller 19 is flush with the first material passage gap, so that the material strip 22 can pass smoothly through the first material passage gap in the second direction. The third unwinding tension roller 21, the fourth unwinding tension roller 20 and the fifth unwinding tension roller 19 are arranged at the same height and are compactly arranged, which further improves the tension of the material strip 22 and improves the accuracy of cutting and polishing discs.
[0057] Optionally, the polishing disc cutting device provided in this application embodiment further includes a take-up side roller group located between the laser cutter 23 and the take-up roller 09 in the second direction. The take-up side roller group is installed on the body 05. The unwinding side roller group includes a third positioning roller 15 and a fourth positioning roller 14 arranged parallel to each other. The axial direction of the third positioning roller 15 is perpendicular to both the first direction and the second direction. A second material passage gap is left between the third positioning roller 15 and the fourth positioning roller 14. At the second material passage gap, both the third positioning roller 15 and the fourth positioning roller 14 are tangent to the second direction. In the first direction, the distance between the laser cutter 23 and the second material passage gap is equal to the distance between the laser cutter 23 and the second material passage gap. This facilitates the positioning and tensioning of the strip 22 from both sides of the positioning member 16 in the second direction, making it difficult for the strip 22 to bend during the laser cutter 23 cutting the strip 22, further improving the accuracy of cutting the polishing disc.
[0058] Optionally, the axis of the take-up roller 09 in the first direction is located above the third positioning roller 15 and the fourth positioning roller 14. In this way, the strip 22, after being cut by the polishing disc, passes through the second feed gap in the second direction and extends towards the top of the take-up roller 09 at a certain inclination, so that the strip 22 itself is in a taut state. This prevents the strip 22 from curling when the laser cutter 23 cuts it, thereby improving the cutting accuracy. In this embodiment, the take-up roller 09 is fixed to the body 05 by the second connecting rod 08.
[0059] Optionally, the take-up side roller group further includes a first take-up tension roller 10, a second take-up tension roller 07, and a third take-up tension roller 11 arranged sequentially in the second direction. The first take-up tension roller 10, the second take-up tension roller 07, and the third take-up tension roller 11 are all located between the take-up roller 09 and the third positioning roller 15. The first take-up tension roller 10 is positioned close to the take-up roller 09, and the second take-up tension roller 07 is located below the first take-up tension roller 10 and the third take-up tension roller 11. In this way, after the material strip 22 is fed out from the second material passage gap in the second direction, it sequentially passes over the third unwinding tension roller 21 from top to bottom, passes over the second unwinding tension roller 04 from bottom to top, passes over the first unwinding tension roller 03 from top to bottom, and then winds onto the take-up roller 09. This further improves the tension of the material strip 22 and enhances the accuracy of cutting and polishing discs.
[0060] Optionally, the take-up side roller group further includes a fourth take-up tension roller 12 and a fifth take-up tension roller 13 arranged in the second direction. The fourth take-up tension roller 12 and the fifth take-up tension roller 13 are both located between the third take-up tension roller 11 and the third positioning roller 15. The fourth take-up tension roller 12 is arranged close to the third take-up tension roller 11. In the first direction, the distance between the top end of the third take-up tension roller 11 and the laser cutter 23, the distance between the top end of the fourth take-up tension roller 12 and the laser cutter 23, the distance between the top end of the fifth take-up tension roller 13 and the laser cutter 23, and the distance between the second material passage gap and the laser cutter 23 are the same. In this way, after the material strip 22 is fed out from the second material passage gap, it passes over the fifth take-up tension roller 13 from top to bottom, then passes over the fourth unwinding tension roller 20 from bottom to top, the third unwinding tension roller 21 from top to bottom, the second unwinding tension roller 04 from bottom to top, the first unwinding tension roller 03 from top to bottom, and finally winds onto the take-up roller 09. The top of the fifth take-up tension roller 13 is flush with the second material passage gap, allowing the material strip 22 to pass smoothly through the second material passage gap in the second direction. The third take-up tension roller 11, the fourth take-up tension roller 12, and the fifth take-up tension roller 13 are arranged at the same height and are compactly arranged, further improving the tension of the material strip 22 and improving the accuracy of cutting the polishing disc. It is understood that in the embodiments of this application, all the rollers included in the polishing disc cutting device are parallel to each other. In this embodiment of the application, preferably, a camera 24 can also be set near the laser to collect images of the positioning component 16 and assist in positioning the positioning hole 27 on the material strip 22; the receiving box can be pulled out and inserted into the body 05 to facilitate the removal of the polishing discs collected by the receiving box.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
