[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0042] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0043] Depending on the context, the words “if” or “suppose” as used here can be interpreted as “when” or “in response to determination” or “in response to detection.” Similarly, depending on the context, the phrases “if determination” or “if detection (of the stated condition or event)” can be interpreted as “when determination” or “in response to determination” or “when detection (of the stated condition or event)” or “in response to detection (of the stated condition or event).”

[0044] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0045] like Figures 1 to 20 As shown, an automatic straightening roller surface grinding device of the present invention is characterized by comprising an X-axis support device 100, an X-axis large crossbeam 200 and an X-axis small crossbeam 300, a Y-axis moving device 400, a Z-axis lifting device 500 and a grinding camera device 600.

[0046] like Figure 1 and Figure 2 The Z-axis lifting device 500 is slidably disposed on the upper part of the Y-axis moving device 400; the X-axis support device 100 is installed through the Z-axis lifting device 500; the X-axis large crossbeam 200 is slidably disposed on the X-axis support device 100; the X-axis small crossbeam 300 is slidably disposed on the X-axis large crossbeam 200; and the grinding camera device 600 is installed at the front end of the X-axis small crossbeam 300.

[0047] Specifically, in this embodiment, the Z-axis lifting device 500 is installed on top of the Y-axis moving device 400, and the support device 100 is installed inside the Z-axis lifting device 500 for use with it. That is, the X-axis moving support device 100 of this invention is placed inside the Z-axis lifting device 500 and slidably connected to it. The angle between the connection between the X-axis moving support device and the Z-axis lifting device 500 can be adjusted. Since the X-axis main beam is relatively long, it is inevitable that it will bend during operation, which will affect the grinding of the grinding camera device 600. In order to keep the X-axis main beam in a horizontal state and to effectively grind it, the angle between the connection between the X-axis moving support device and the Z-axis lifting device 500 in this invention can be adaptively adjusted. That is, the gap between the two can be adjusted to achieve a compensation effect. The gap can be adjusted by adjusting the screw spacing to ensure that the X-axis main beam 200 always remains in a horizontal state.

[0048] The X-axis small crossbeam 300 is placed inside the X-axis large crossbeam 200 and slidably connected to it. The grinding camera device 600 is installed at the front end of the X-axis small crossbeam 300. The X-axis large crossbeam 200 is placed inside the support device 100 and slidably connected to it. During operation, the Z-axis lifting device 400 drives the support device 100 of the present invention to move up and down to adjust the grinding position of the grinding camera device 600. The drive motor 32 of the support device 100 of the present invention drives the X-axis large crossbeam 200 to move inside it to adjust its grinding position, so as to effectively grind the straightening roller 700.

[0081] This invention is installed at the front end of the small crossbeam of the X-axis of the grinding equipment, and the large crossbeam of the X-axis is installed in the X-axis support device and slides within it to achieve position adjustment in the X-axis direction. Through the cooperation between the Y-axis moving device and the Z-axis lifting device, the grinding camera device can be precisely moved to the position of the straightening roller to be ground, realizing the effect of automatic damage finding and automatic grinding; reducing the labor intensity of manual labor and improving the safety of operation for safe production.

[0082] The usage parameters of this invention are as follows:

[0083] Assuming there is a protruding object on one straightening roller (referred to as the roller), the roller diameter is Φ360mm, the detection length of the high-definition camera on the roller is limited to 100mm, the surface linear velocity of the roller is 12000mm / min (200mm / s), one rotation of the roller takes 6 seconds, and the minimum identification point diameter is ≥1mm, the time required to detect one roller is 30 seconds. Detecting 5 rollers takes 150 seconds. The time required for the 4×800mm Y-axis movement is 10×4=40s, totaling 150s+40s=190s. After finding the roller with the protruding object, the grinding time is 15s (including the grinding head movement time), and the camera re-inspection time after grinding is 15s.

[0084] The total time is 190s + 15s + 15s = 220s. The X-axis entry time is 30s and the exit time is 30s, for a total of 220s + 60s = 280s (4 minutes and 40 seconds). The equipment is then ready for use. If only one or two rollers are being inspected, the above time will be significantly reduced.

[0085] The above 4 minutes and 40 seconds is the time required for a high-definition camera to detect 5 rollers with a minimum identification point diameter of ≥1mm. If a roller can be ground in advance, the required time is: Y-axis travel time 10s + X-axis travel time 30s + sensor detection time 30s + grinding time 15s + camera re-inspection time 15s = 10 + 30 + 30 + 15 + 15 = 100s (1 minute and 40 seconds).

[0086] If the minimum identification point diameter is ≥0.5mm, the total time is 18 minutes. Grinding only one roller takes about 4 minutes.

[0087] If the minimum identification point diameter is ≥0.1mm, the total time is 32 minutes. Grinding only one roller takes about 8 minutes.

[0088] In this embodiment, the endoscope, or high-definition camera, is a Cognex 5-megapixel industrial-grade camera used to monitor the roller surface in real time.

[0089] The new ultra-compact, standalone vision system delivers industry-leading vision tool performance at PC speeds, features Power over Ethernet, and provides superior standalone vision capabilities for integration into smaller spaces.

[0090] The present invention relates to a grinding camera device located at the front end of a small crossbeam on the X-axis. A rotating servo motor enables grinding of both the upper and lower sets of straightening rollers. Equipped with a high-definition endoscope and dedicated lighting, it provides more precise damage detection. Through the coordination of the Y-axis moving device and the Z-axis lifting device, the grinding camera device can be quickly and accurately positioned to the location on the straightening roller requiring grinding, achieving automatic damage detection and automatic grinding. This reduces manual labor intensity and improves operational safety for safe production.

[0091] This invention proposes to add an online non-standard fully automatic or semi-automatic surface grinding device for the straightening rollers in the finishing area of ​​the thick plate section, utilizing the existing space and ground outside the straightening machine. This reduces the labor intensity of manual labor and improves operational safety for safe production. The invention features a grinding camera at the front end of the X-axis small crossbeam. Through the coordination of the Y-axis moving device, the Z-axis lifting device, and the X-axis large crossbeam, the device can be precisely moved to the position of the straightening roller to be ground, achieving automatic damage detection and automatic grinding. Furthermore, the connection between the X-axis moving support device and the Z-axis lifting device allows for effective compensation to adjust the position of the X-axis large crossbeam, ensuring the entire X-axis is on the same horizontal line, facilitating equipment maintenance.

[0092] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention. All equivalent changes and modifications made in accordance with the scope of the claims of this invention should fall within the technical scope of this invention.
