[0035] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0037] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] Combination Figure 1 , Figure 2 and Figure 9 The grinding and marking device 100 of the present invention can be used in welding equipment having a welding device 700, for example, in welding such as Figure 2 When welding product 900 as shown, before welding, that is, before welding the workpiece 91 to be ground and scribed to a vertical plate 92, the surface of the workpiece 91 to be ground and scribed needs to be ground first to remove rust and repair unevenness on the surface of the workpiece 91 to be ground and scribed. This results in several relatively flat welding areas 9101 for the vertical plate being welded on the surface of the workpiece 91 to be ground and scribed. Then, a marking line 9102 is drawn at the center of the welding area 9101. Therefore, when welding product 900, the center of the thickness surface of the vertical plate 92 can be aligned with the marking line 9102, and the workpiece 91 to be ground and scribed and the vertical plate 92 can be welded together along the grinding direction S of the welding area 9101, ensuring the welding quality of product 900. However, it should be noted that the scope of application of the grinding and scribing device 100 of the present invention includes, but is not limited to, this; only a detailed application example is shown here to help those skilled in the art understand the present invention.

[0040] Combination Figure 3 and Figure 4 A preferred embodiment of the present invention, a grinding and marking device 100, will be described in detail below, wherein the grinding and marking device 100 includes a conveying mechanism 10, a grinding mechanism 20 and an inkjet mechanism 30.

[0041] Preferably, combined with Figure 3 The conveying mechanism 10 has a conveying surface 101 for conveying the workpiece 91 to be polished and scribing along the polishing direction S.

[0042] The grinding mechanism 20 includes at least one grinding component 21, which has a rotatable grinding wheel 211. The grinding wheel 211 is disposed above the conveying surface 101, thereby cooperating with the conveying mechanism 10. When the workpiece 91 to be ground and scribing is conveyed past the grinding wheel 211, the workpiece 91 to be ground and scribing is rotated and ground, thereby forming the vertical plate welding area 9101 extending along the grinding direction S on the upper surface of the workpiece 91 to be ground and scribing.

[0043] Combination Figure 3 and Figure 4 The inkjet mechanism 30 includes at least one inkjet assembly 31, which has an inkjet pen 311. The inkjet pen 311 is disposed above the conveying surface 101 and downstream of the grinding wheel 211, thereby cooperating with the conveying mechanism 10 and the grinding wheel 211. When the workpiece 91 to be ground and scribing is conveyed past the inkjet pen 311 after grinding, a marking line 9102 extending along the grinding direction S is drawn in the vertical plate welding area 9101.

[0044] Therefore, combined Figure 3 and Figure 4 The present invention provides a grinding and scribing method, which uses the grinding and scribing device 100 described above to grind and scribing the workpiece 91 to be ground and scribed, including the following steps:

[0045] S10: The workpiece 91 to be ground and scribing is conveyed along the grinding direction S by the conveying mechanism 10.

[0046] S20: When the workpiece 91 to be ground and scribing is conveyed below the grinding wheel 211, the grinding wheel 211 is driven to rotate, thereby forming the vertical plate welding area 9101 extending along the grinding direction S on the upper surface of the workpiece 91 to be ground and scribing.

[0047] S30: When the workpiece 91 to be polished and marked is conveyed below the inkjet pen 311, the inkjet pen 311 is driven to spray ink, thereby marking a line 9102 extending along the polishing direction S in the vertical plate welding area 9101.

[0048] Therefore, the grinding and scribing device 100 of the present invention realizes automatic grinding and scribing of the workpiece 91 to be ground and scribed, with high efficiency and low cost.

[0049] Furthermore, there may be multiple grinding components 21 and inkjet components 31, and the multiple grinding components 21 and inkjet components 31 are distributed at intervals along a direction perpendicular to the grinding direction S, and the multiple grinding components 21 and inkjet components 31 are arranged in a one-to-one correspondence, thereby further improving the grinding and scribing efficiency of the workpiece 91 to be ground and scribing.

[0050] According to some preferred embodiments of the present invention, in combination with Figure 5 The grinding assembly 21 also includes a grinding drive motor 212, an annular transmission belt 213, and at least two transmission shafts 214.

[0051] At least two drive shafts 214 are rotatably fitted inside the annular drive belt 213, and at least one of the drive shafts 214 is connected to the grinding drive motor 212, and at least another drive shaft 214 is connected to the grinding wheel 211. Thus, the grinding drive motor 212 drives the grinding wheel 211 to rotate, thereby grinding the upper surface of the workpiece 91 to be ground to form the vertical plate welding area 9101.

[0052] In other words, after the driving motion is output from the grinding drive motor 212, it is transmitted to the grinding wheel 211 through the annular transmission belt 213 and at least two transmission shafts 214, thereby realizing the automatic rotation of the grinding wheel 211. The belt drive has low noise, smooth movement, and low vibration, which helps to ensure the smooth operation of the grinding wheel 211 during the grinding process.

[0053] According to some preferred embodiments of the present invention, the grinding mechanism 20 includes at least one grinding lifting component 22, the grinding lifting component 22 including a lifting slide rail 221, a lifting slide block 222 and a lifting drive component 223.

[0054] The lifting slide rail 221 extends vertically and is located above the conveying surface 101. The lifting slide block 222 is slidably disposed within the lifting slide rail 221, and the grinding component 21 is mounted on the lifting slide block 222. For example, the grinding drive motor 212 is directly fixedly mounted on the lifting slide block 222. The lifting drive component 223 is connected to the lifting slide block 222, thereby driving the lifting slide block 222 to slide along the lifting slide rail 221, thereby driving the grinding component 21 to rise and fall. This allows the component to either descend to approach the workpiece 91 to be ground and grind it, or rise away from the workpiece 91 and cease grinding it.

[0055] Therefore, the present invention can adjust the height of the grinding wheel 211 through the grinding lifting component 22, thereby adjusting the grinding thickness of the grinding wheel 211 and enabling the grinding wheel 211 to grind the workpiece 91 to be ground with different thicknesses, thus improving the grinding applicability of the grinding wheel 211.

[0056] According to some examples of the present invention, the lifting slide 222 is configured as a nut seat, and the lifting drive component 223 may include a lifting drive motor 2231 and a threaded rod 2232. The lifting drive motor 2231 is connected to the threaded rod 2232, and the threaded rod 2232 is threadedly connected in the lifting slide 222, thereby enabling the automatic sliding of the lifting slide 222 by the lifting drive motor 2231.

[0057] According to other embodiments of the present invention, the lifting drive component 223 may also be a lifting drive cylinder, and the lifting slide rail 221 may extend inclined in the vertical direction. Thus, the lifting drive cylinder provides a small driving force to tilt and pull the workpiece 91 to be polished and scribing to achieve the lifting and lowering of the polishing wheel 211.

[0058] According to some preferred embodiments of the present invention, in combination with Figure 5 and Figure 6The grinding assembly 21 includes a grinding clamping assembly 23. The upper end of the grinding clamping assembly 23 is connected to the grinding assembly 21, for example, directly and fixedly connected to the transmission housing outside the annular transmission belt 213 or the housing of the grinding drive motor 212. The lower end is a free end, and the grinding clamping assembly 23 is extendable in the vertical direction. When the grinding clamping assembly 23 moves away from the workpiece 91 to be ground as the grinding assembly 21 moves away from the workpiece 91, the grinding clamping assembly 23 is in an extended state, and the height of the lower end of the grinding clamping assembly 23 is lower than the height of any point on the grinding wheel 211. When the grinding clamping assembly 23 approaches and contacts the workpiece 91 to be ground as the grinding assembly 21 moves closer to the workpiece 91, the grinding clamping assembly 23 retracts and presses the workpiece 91 to be ground onto the conveying surface 101 before grinding. In this way, the entire weight of the grinding assembly 21 can be supported on the workpiece 91 to be ground and scribing. On the one hand, this effectively prevents the grinding assembly 21 from wobbling due to prolonged suspension. On the other hand, the weight of the grinding assembly 21 itself can automatically press the workpiece 91 to be ground and scribing, preventing it from shaking during grinding. In addition, the grinding clamping assembly 23 can also ensure the grinding stability and reliability of the grinding wheel 211 during subsequent grinding, and it has a compact structure and occupies little space.

[0059] Furthermore, combined Figure 6 and Figure 7 The grinding and clamping assembly 23 includes an outer cylinder 231, a clamping inner rod 232, and an elastic element 233. The outer cylinder 231 is connected to the grinding assembly 21 and extends vertically. The clamping inner rod 232 is axially movable within the outer cylinder 231. The elastic element 233 connects the clamping inner rod 232 and the outer cylinder 231. When the grinding and clamping assembly 23 descends closer to the workpiece 91 to be ground and scribed, the clamping inner rod 232 contacts the workpiece 91 and retracts within the outer cylinder 231, and the elastic element 233 is subjected to force. Consequently, when the grinding and clamping assembly 23 rises away from the workpiece 91 to be ground and scribed, the elastic element 233 provides elastic force to drive the clamping inner rod 232 to move away from the top wall of the outer cylinder 231, thereby restoring the grinding and clamping assembly 23 to its extended state. Therefore, the grinding and pressing assembly 23 can automatically switch between the extended state and the contracted state, with high extension efficiency and automation.

[0060] Specifically, the elastic element 233 can be a spring sleeve.

[0061] According to some preferred embodiments of the present invention, in combination with Figure 3 , Figure 5 and Figure 6 The grinding mechanism 20 includes a grinding adjustment component 24, which includes at least a grinding adjustment seat 241, a grinding adjustment rack 242, at least a grinding adjustment gear 243 and at least a grinding adjustment motor 244.

[0062] The grinding lifting assembly 22 is mounted on the grinding adjustment base 241. For example, the lifting slide rail 221 of the grinding lifting assembly 22 is directly fixedly mounted on the grinding adjustment base 241. The grinding adjustment rack 242 extends in a direction perpendicular to the grinding direction S. The grinding adjustment gear 243 meshes with the grinding adjustment rack 242. The grinding adjustment motor 244 is connected to the grinding adjustment gear 243 and is mounted on the grinding adjustment base 241, thereby driving the adjustment of the grinding position of the grinding wheel 211.

[0063] Therefore, the present invention drives the grinding adjustment gear 243 to move along the extension direction of the grinding adjustment rack 242 by the grinding adjustment motor 244, thereby driving the grinding adjustment seat 241, which is equipped with the grinding lifting component 22 and the grinding component 21, to move. This achieves the adjustment of the position of the grinding wheel 211 in the grinding component 21, thereby forming the vertical plate welding area 9101 in different areas of the workpiece 91 to be ground and scribing, improving the grinding applicability of the grinding wheel 211, and helping to ensure that the grinding wheel 211 and the inkjet pen 311 can cooperate with each other during operation.

[0064] In addition, the above-mentioned configuration also allows the position between the two grinding wheels 211 to be adjustable, thereby enabling the adjustment of the interval distance between the two vertical plate welding areas 9101.

[0065] Furthermore, combined Figure 5 The grinding mechanism 20 includes a grinding adjustment slide rail 245, which is spaced apart from the grinding adjustment rack 242 and extends in the same direction. The grinding adjustment seat 241 is slidably engaged with the grinding adjustment slide rail 245. Therefore, the grinding adjustment slide rail 245 can guide the grinding adjustment seat 241 to slide stably in a direction perpendicular to the grinding direction S, thereby ensuring the smooth progress of the adjustment process.

[0066] According to some preferred embodiments of the present invention, in combination with Figure 8The inkjet assembly 31 includes an inkjet lifting component 312. The inkjet lifting component 312 is connected to the inkjet pen 311, thereby driving the inkjet pen 311 to descend closer to the workpiece 91 to be ground and scribing, so as to scribing the center of the vertical plate welding area 9101, or to rise away from the workpiece 91 to be ground and scribing, and thus stop scribing.

[0067] Specifically, the inkjet lifting component 312 can be an inkjet lifting cylinder.

[0068] According to some preferred embodiments of the present invention, in combination with Figure 8 The inkjet mechanism 30 includes an inkjet positioning assembly 32, which includes at least one inkjet positioning base 321, an inkjet positioning rack 322, at least one inkjet positioning gear 323, and at least one inkjet positioning motor 324. The inkjet assembly 31 is mounted on the inkjet positioning base 321. The inkjet positioning rack 322 extends in a direction perpendicular to the polishing direction S. The inkjet positioning gear 323 meshes with the inkjet positioning rack 322. The inkjet positioning motor 324 is connected to the inkjet positioning gear 323 and is installed on the inkjet positioning base 321. The inkjet positioning motor 324 drives the inkjet pen 311 to adjust the inkjet position, thereby forming the marking line 9102 in different areas of the workpiece 91 to be polished and scribbled. This improves the inkjet application range of the inkjet pen 311 and helps to ensure that the polishing wheel 211 and the inkjet pen 311 can cooperate accordingly.

[0069] Therefore, the present invention drives the inkjet positioning gear 323 to move along the extension direction of the inkjet positioning rack 322 via the inkjet positioning motor 324, thereby moving the inkjet positioning base 321 on which the inkjet assembly 31 is mounted, and thus realizing the adjustment of the position of the inkjet pen 311 in the inkjet assembly 31. In addition, the above arrangement also makes the position between the two inkjet pens 311 adjustable.

[0070] Furthermore, the inkjet mechanism 30 includes an inkjet positioning slide rail 325, which is spaced apart from the inkjet positioning rack 322 and extends in the same direction. The inkjet positioning seat 321 is slidably engaged with the inkjet positioning slide rail 325. Thus, the inkjet positioning slide rail 325 can guide the inkjet positioning seat 321 to slide stably in a direction perpendicular to the polishing direction S, thereby ensuring the smooth progress of the positioning process.

[0071] According to some preferred embodiments of the present invention, in combination with Figure 1 and Figure 3 The grinding and marking device 100 includes a dust collection mechanism 40, which includes a dust collection hood 41 and an exhaust fan 42.

[0072] The dust collection hood 41 includes a dust collection hood body 411 and a dust collection hood door 412. The dust collection hood body 411 forms a dust collection inlet chamber 4101, which is used to cover the outside of the polishing mechanism 20. The side of the dust collection hood body 411 away from the inkjet assembly 31 forms a portion that communicates with the dust collection inlet chamber 4101 and is aligned with an inlet 4102 of the conveying mechanism 10. The dust collection hood door 412 is rotatably connected to the dust collection hood body 411, thereby opening or closing the inlet 4102 by rotation. The exhaust fan 42 is connected to both the dust collection inlet chamber 4101 and the dust collection and treatment system.

[0073] Therefore, before grinding the workpiece 91 to be ground and scribing, the workpiece 91 can be placed on the conveying surface 101 of the conveying mechanism 10 through the feed port 4102, and then the dust collection hood 412 can be closed. In this way, when the grinding mechanism 20 grinds the workpiece 91, the dust collection mechanism 40 will collect the dust generated on the surface of the workpiece 91 and hand it over to the dust treatment system for unified treatment, avoiding dust flying around in the production workshop and improving the cleanliness of the production workshop.

[0074] According to some preferred embodiments of the present invention, in combination with Figure 3 The conveying mechanism 10 includes a conveying machine tool 11 and a plurality of conveying rollers 12. The plurality of conveying rollers 12 are rotatably mounted on the conveying machine tool 11 and are spaced apart along the grinding direction S. The roller surfaces of the plurality of conveying rollers 12 constitute the conveying surface 101. Thus, when the conveying rollers 12 rotate, the workpiece 91 to be ground and scribing placed on the conveying rollers 12 is driven to move along the grinding direction S.

[0075] The present invention also provides a welding device, including the grinding and marking device 100 and the welding device 700 as described above, wherein the welding device 700 is mounted on both sides of the conveying mechanism 10. Thus, after the workpiece 91 to be ground and marked is ground and marked, the welding torch of the welding device can weld the workpiece 91 and the vertical plate 92 together in the vertical plate welding area 9101 along the grinding direction S. In this way, because the present invention performs sufficient welding accuracy work before welding, it can ensure the fit and position of the two parts during welding, thereby ensuring the welding quality.

[0076] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments; without departing from these principles, the implementation of the present invention may be modified or altered in any way.
