Description

Technical Field

[0001] The invention belongs to the technical field of plate detection, and relates to a device for detecting the apparent plate shape of a medium and thick copper alloy plate. Background Art

[0002] With the development of medium and thick plate applications such as power electrodes for new energy vehicles, customer requirements for copper strip surface quality and flatness are increasing year by year. Poor flatness of rolled plate often causes abnormal bonding during bell-type furnace annealing, seriously affecting surface quality.

[0003] Currently, there are two main methods for inspecting the shape of medium and thick plate. The first involves directly using a thin plate shape roller. While this roller can accurately obtain shape information online, it requires contact with the plate's surface to detect the shape. Medium and thick plate is thicker, and during the blanking process, many defects may appear on the plate surface or sides, such as milling cutter marks, which often appear on milled material. These defects can damage the inspection equipment and rapidly reduce its service life. The second method involves manual tapping, which damages the strip's sides, requires high-level technical skills from the workers, and can also lead to subjective evaluation.

[0004] Therefore, it is necessary to find a detection method that is low-cost, convenient to detect, and suitable for medium and thick plates. Summary of the Invention

[0012] Preferably, the laser angle adjustment frame and the reference plate angle adjustment frame are rotatably fixed on the fixing frame via a first rotating shaft and a second rotating shaft respectively.

[0013] Preferably, when the plate surface angle detection vehicle zeroes the laser line emitted by the laser emitting station, the plate type reference plate is perpendicular to the reflected light reflected by the plate.

[0014] Preferably, the fixing frame and the bracket are both aluminum alloy brackets.

[0015] Preferably, the thickness of the plate is 1.0-16.0 mm.

[0016] The present invention has the following beneficial effects: (1) In this application, the laser beam emitted from the laser launch station is irradiated on the plate, and after being reflected by the plate, a clear dot pattern is formed on the plate profile reference plate.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further explained and illustrated by means of specific embodiments below.

[0022] The present application provides a device for detecting the apparent shape of copper alloy medium and thick plates. The device can detect the apparent shape of copper alloy medium and thick plates with a thickness of 1.0-16.0 mm online based on the existing rolling mill equipment. In the embodiment of the present application, the device for detecting the apparent shape of copper alloy medium and thick plates includes a fixing frame 1, a bracket 2, a laser emitting platform 5, a plate shape reference plate 6, and a plate surface angle detection vehicle 7, as shown in the attached figure. Figure 1 shown.

[0023] Both the fixed frame 1 and the bracket 2 are support components in this application, each having different configurations. When testing the apparent shape of a medium and thick copper alloy plate, the fixed frame 1 and the bracket 2 are positioned on the same side of the existing rolling mill equipment, without direct contact with the mill, to facilitate apparent shape testing of the rolled plate 8. The fixed frame 1 and bracket 2 are adaptable to different types of rolling mills.

[0024] The top of the fixed frame 1 is equipped with a laser launch platform 5 and a plate-shaped reference plate 6 via a laser angle adjustment frame 3 and a reference plate angle adjustment frame 4, respectively. The laser angle adjustment frame 3 and the reference plate angle adjustment frame 4 are rotatably fixed to the fixed frame 1 via a first rotating shaft 12 and a second rotating shaft 13, respectively. Thus, adjusting the rotation angles of the laser angle adjustment frame 3 and the reference plate angle adjustment frame 4 respectively can adjust the angles of the laser launch platform 5 and the plate-shaped reference plate 6. Furthermore, the first rotating shaft 12 and the second rotating shaft 13 are both lockable rotating shafts, allowing them to be locked after their angles are adjusted.

[0025] In the embodiment of the present application, a plurality of laser lamps 11 are provided on the laser emitting platform 5. The plurality of laser lamps 11 can emit laser lines in parallel and irradiate the plate 8. Figure 2 The plate type reference plate 6 is a frosted tempered glass plate with an XY axis grid pattern, which can receive the laser line reflected by the plate 8, as shown in the attached figure. Figure 3 Preferably, the grid size of the plate shape reference plate 6 is 2-4 cm, so as to accurately detect the apparent plate shape of the plate 8.

[0026] Mounted on bracket 2 is a panel angle detection vehicle 7. Laser light from a laser emitting station 5 illuminates panel 8. After reflection from panel 8, the laser light forms a clear spot pattern on the panel reference plate 6. By observing the range of movement of the light spot in the spot pattern on panel reference plate 6, apparent panel shape problems can be identified online. A significant deviation in the range of movement between the light spots on both sides and the center of panel reference plate 6 indicates poor panel quality.

[0027] In the embodiment of the present application, in order to enable the fixing frame 1 and the bracket 2 to resist corrosion caused by the emulsion vapor, the fixing frame 1 and the bracket 2 in the embodiment of the present application are both aluminum alloy brackets, and the surface needs to be oxidized.

[0028] In order to enable the apparent plate shape detection device of copper alloy medium and thick plates to detect the apparent plate shape of the plate 8 located between the deflector roller 9 and the winding roller 10, in the horizontal direction, the laser launch platform 5 and the plate shape reference plate 6 are arranged between the deflector roller 9 and the winding roller 10 of the rolling mill; in the vertical direction, the laser launch platform 5 and the plate shape reference plate 6 are both arranged above the deflector roller 9.

[0029] The board surface angle detection vehicle 7 is a component for zeroing the laser line emitted by the laser launch station 5, specifically calibrating whether the center laser point in the laser line emitted by the laser launch station 5 coincides with the center grid point on the board reference plate 6. In the embodiment of the present application, the board surface angle detection vehicle 7 includes a frame 701, a guide wheel 702 arranged at the bottom of the frame 701, and a protractor 703 arranged on both sides of the frame 701, as shown in the attached figure. Figure 4As shown. To ensure that the panel angle detection vehicle 7 is mounted on the bracket 2 and can rotate around the bracket 2, the protractor 703 in this embodiment of the present application is rotated on the mounting bracket 2 via a connecting rod 704, and the end of the connecting rod 704 is mounted on the top of the bracket 2 via a third rotating shaft 705. During use, the four guide wheels 702 of the panel angle detection vehicle 7 must be fully aligned with the plate 8 to prevent angle deviation and, in turn, prevent erroneous angle data readings by the protractor 703.

[0030] When the board surface angle detection vehicle 7 is zeroing the laser beam emitted by the laser emitting platform 5, the four guide wheels 702 of the board surface angle detection vehicle 7 are completely aligned with the board 8, and the angle data is read using the protractor 703. The angle of the reference plate angle adjustment frame 4 is manually coarsely adjusted so that the board type reference plate 6 is perpendicular to the reflected light from the board 8, completing the zeroing operation.

[0031] The use process of the copper alloy medium and thick plate apparent plate shape detection device in the embodiment of the present application is as follows: After the sheet 8 passes through the deflector rollers 9 and tension is established on the take-up rollers 10, the rolling mill enters a stable rolling process. After reducing the mill's operating speed, the third rotating shaft 705 is rotated so that the four guide rollers 702 are fully aligned with the sheet. At this point, the plate angle detection vehicle 7 lands on the sheet 8. After reading the angle data using the protractor 703, the second rotating shaft 13 is manually rotated to adjust the angle of the reference plate angle adjustment frame 4, thereby adjusting the angle of the plate shape reference plate 6. Simultaneously, the laser lamp 11 on the laser launch station 5 is activated. The laser beam emitted by this laser lamp 11 illuminates the sheet 8. The laser beam, reflected from the sheet 8, forms a clear projection point on the plate shape reference plate 6. The second rotating shaft 13 is further rotated so that the center point of the laser beam reflected from the sheet 8 coincides with the center grid point on the plate shape reference plate 6, completing the zeroing operation. After adjusting the mill's operating speed to the standard speed, the operator reads the plate shape information by observing the plate shape reference plate 6.

[0032] During normal production, as the thickness of the plate 8 on the winding roller 10 gradually increases, the points on the plate reference plate 6 will vibrate in the same direction and frequency, forming an attached Figure 5 The graph shown is the plate shape reference plate display diagram when the plate 8 has no apparent plate shape problem. When the plate 8 has an apparent plate shape problem, such as a double-sided wave apparent plate shape problem, the fluctuation frequency, amplitude and direction of the light points on both sides will be different from those of the middle point, and the more severe the side waves are, the greater the fluctuation amplitude will be. Figure 6 shown.

[0033] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
