Description

Technical Field

[0001] This disclosure relates to the field of testing equipment technology, and in particular to an online testing device for the surface morphology of rolls. Background Technology

[0002] Micro-machining of the current collector surface can enhance the adhesion of the positive and negative electrode materials of the battery to the current collector, thereby improving battery life and other performance.

[0003] Common methods for micro-machining of current collector surfaces include texturing rolling. The principle is to use a special pulsed laser to preheat and strengthen the surface of the roll, forming a tiny molten pool at the aggregation point. At the same time, a side-blowing device is used to make the molten material in the molten pool accumulate as much as possible to the edge of the molten pool to form an arc-shaped boss. The boss is rapidly cooled under the self-conducting heat of the roll to form a hardening zone. Then, through cold rolling, the boss on the roll is formed into a three-dimensional surface structure on the foil surface.

[0004] Therefore, the micro-morphology and distribution of the roll surface directly affect the performance of the current collector. Thus, it is necessary to conduct online detection of the micro-morphology on the roll surface during the micro-morphing process. This will allow for timely detection of problems, timely adjustment and repair of the micro-morphing process, saving processing time and improving production efficiency.

[0005] Existing methods for micro-morphological inspection include two approaches: one involves workers using a handheld microscope to observe and inspect the micro-morphological features on the roll surface. This method not only lacks precise positioning and measurement capabilities but also requires significant physical exertion from the workers. The other approach is offline inspection, which involves removing the roll after it has been fully processed and inspecting it using a digital microscope. However, due to the limited space in the base of the digital microscope, there are certain limitations on the roll diameter. Once the roll diameter reaches a certain value, it becomes impossible to inspect the roll, resulting in low inspection efficiency. Summary of the Invention

[0006] One of the technical problems that this disclosure aims to solve is that existing methods for detecting the micro-morphology of roll surfaces suffer from inaccurate detection results, limited detection range, and low detection efficiency.

[0044] Reference Figure 1 and Figure 2 According to a preferred embodiment of this application, an online inspection device for the surface morphology of a roll can be used to inspect the micro-morphology of the roll surface, thereby improving inspection accuracy and production efficiency. The device includes: a microscope 1 for inspecting the surface morphology of the roll; an X-axis sliding assembly 2 configured to allow the microscope 1 to slide lockably along the X-axis; a Y-axis sliding assembly 3 configured to allow the microscope 1 to slide lockably along the Y-axis; and a Z-axis sliding assembly 4 configured to allow the microscope 1 to slide lockably along the Z-axis. Any one of the X-axis sliding assembly 2, Y-axis sliding assembly 3, and Z-axis sliding assembly 4 can be mounted as a mounting base around a roll laser processing center so that the microscope 1 can approach the roll to inspect the surface morphology of the roll.

[0045] Preferably, microscope 1 is a digital microscope. A digital microscope can be connected to electronic equipment, allowing the image within microscope 1 to be directly displayed on an LCD screen. When observing an object, the digital microscope can generate an upright three-dimensional image and magnify the image before displaying it on a computer screen. With measurement software, various data can be measured, recorded, and saved. Of course, to further improve the detection of the micro-morphology of the roll surface, microscope 1 can also be selected from other types of microscopes with higher precision.

[0046] Reference Figure 1 and Figure 2 When inspecting the surface micro-shape of the roll during its processing, the microscope 1 is moved according to the size of the roll and the changes in the processing position. By continuously moving the microscope 1, it is positioned at a reasonable inspection location. While ensuring inspection accuracy, the surface micro-shape of the roll is recorded, allowing workers to promptly identify and adjust any abnormalities. If unprocessed parts exist on the roll, they can be precisely located and repaired using a digital microscope. Furthermore, this application has the advantages of simple structure and easy installation, further saving time and improving production efficiency. For rolls of different sizes and specifications, since the microscope 1 in this application can move simultaneously in the X, Y, and Z directions, it can inspect rolls of various sizes and specifications, significantly expanding its applicability.

[0047] Reference Figure 2 and Figure 3 In some embodiments, the X-axis sliding assembly 2 includes an X-axis guide rail 21, an X-axis sliding base 22 lockable along the X-axis guide rail 21, and a drive unit capable of driving the X-axis sliding base 22 to slide, with the microscope 1 mounted on the X-axis sliding base 22; the Z-axis sliding assembly 4 includes a Z-axis guide rail 41, a Z-axis sliding base 42 lockable along the Z-axis guide rail 41, and a drive unit capable of driving the Z-axis sliding base 42 to slide, with the X-axis guide rail 21 mounted on the Z-axis sliding base 42; the Y-axis sliding assembly 3 includes a Y-axis guide rail 31, a Y-axis sliding base 32 lockable along the Y-axis guide rail 31, and a drive unit capable of driving the Y-axis sliding base 32 to slide, with the Z-axis guide rail 41 mounted on the Y-axis sliding base 32, wherein the Y-axis guide rail 31 is configured to be mounted around the perimeter of the roll laser processing center.

[0048] Reference Figure 2 and Figure 3Specifically, the drive unit preferably uses a servo motor to enable each sliding base to reciprocate along its respective guide rail, thereby adjusting the position of the microscope 1. In a preferred embodiment, both the X-axis guide rail 21 and the Z-axis guide rail 41 are made of lead screws, and both the X-axis sliding base 22 and the Z-axis sliding base 42 are provided with nuts that cooperate with the lead screws. The rotation of the lead screws driven by the servo motor drives the movement of the X-axis sliding base 22 and the Z-axis sliding base 42, thereby adjusting the X-axis and Z-axis positions of the microscope 1. The Y-axis guide rail 31 is made of a track, and the Y-axis sliding base 32 is connected to the track. The reciprocating motion of the track adjusts the Y-axis position of the microscope 1.

[0049] In another preferred embodiment, the online inspection device for the surface morphology of the rolls may further include a control center. The control center can control the start / stop, speed, and direction of the servo motors to achieve rapid and accurate positioning of the microscope 1 in the X, Y, and Z directions. Furthermore, the control center can also coordinate the location of the microscope 1, making the positioning and inspection results more accurate and effective.

[0052] Specifically, both the first connecting block 2241 and the second connecting block 2242 are square blocks. Since the first connecting block 2241 needs to rotate later, its size should not be too large to avoid affecting subsequent rotation. The connection between the connecting rod 2243 and the first and second connecting blocks 2241 can be detachable, facilitating adjustment of the microscope 1's rotation range. The rotatable structure 226 expands the microscope 1's usability, enabling comprehensive testing of the microstructure morphology and data on the rolls.

[0053] A groove is formed on the peripheral wall of the mounting shaft 225 along its axial direction. A mounting cylinder is provided on the body of the microscope 1, which can be inserted into the mounting shaft 225. A slider that mates with the groove is provided on the inner wall of the mounting cylinder to prevent the microscope 1 from rotating. A fixing member is provided on the outer wall of the mounting cylinder to fix the mounting cylinder and the mounting shaft 225, for example, a fixing bolt that can be inserted into the mounting cylinder and the mounting shaft 225 in sequence.

[0054] Reference Figure 4 and Figure 5 In some embodiments, the rotatable structure 226 includes a plurality of first connecting holes 2261 spaced apart from each other circumferentially along the first connecting block 2241, a first annular groove 2262 cooperating with the first connecting holes 2261, and a fixing pin passing through the first connecting holes 2261 and abutting against the first annular groove 2262. The first annular groove 2262 is formed on the peripheral wall of the fixing shaft 223 and is formed circumferentially thereafter. The plurality of first annular grooves 2262 are spaced apart from each other axially along the fixing shaft 223. The fixing pin enables the first connecting block 2241 to rotate clockwise / counterclockwise around the axial direction of the fixing shaft 223 to adjust the position of the microscope 1.

[0055] In such Figure 5 In a preferred embodiment shown, a first connecting hole 2261 is provided at the center of each of the three sides of the first connecting block 2241. Three annular grooves are provided at equal intervals along the axial direction of the fixed shaft 223. The fixing pin passes through the first connecting hole 2261 and abuts against the first annular groove 2262. The fixing pin can rotate along the first annular groove 2262. In order to ensure the stability of the rotation process, the fixing pin and the first connecting hole 2261 can be set as an interference fit, or a connecting key can be provided between the fixing pin and the first connecting hole 2261.

[0056] In some embodiments, the bottom of the mounting surface is provided with a bolt with the screw facing the fixed shaft 223, and the end face of the fixed shaft 223 is provided with a threaded hole for threaded connection with the bolt;

[0057] The X-axis sliding base 22 also includes two L-shaped fasteners 227 arranged opposite to each other. The horizontal plate of the L-shaped fastener 227 is fixed to the mounting surface of the L-shaped component 222. The vertical plate of the L-shaped fastener 227 protrudes into the L-shaped flared opening of the L-shaped fastener 227 to form an arc-shaped fastening groove. The two arc-shaped fastening grooves can surround and fix the fixed shaft 223.

[0058] In such Figure 5 In a preferred embodiment shown, the nut portion of the bolt is connected to a flat plate for fixing. The flat plate is fixed within the horizontal plate of the L-shaped component 222, thereby increasing the stability of the connection between the bolt and the fixing shaft 223. More preferably, a keyway is provided between the arc-shaped retaining groove and the fixing shaft 223 to further fix the L-shaped retaining member 227 to the fixing shaft 223.

[0059] Reference Figure 5 In some embodiments, the mounting shaft 225 and the second connecting block 2242 are fixed together by a fixing structure 228. The fixing structure 228 includes two keyways that are respectively opened on the wall of the through hole of the second connecting block 2242 and the peripheral wall of the mounting shaft 225, and a connecting ring 2281 disposed on the top of the second connecting block 2242.
