Description

Technical Field

[0001] This utility model relates to the field of flatness detection technology for aluminum composite panels, and in particular to a flatness detection device for aluminum composite panels. Background Technology

[0002] The laser scanning flatness meter for aluminum composite panels is a non-contact optical measuring device based on the principle of laser triangulation. It emits a laser line and scans the surface of a moving aluminum plate, acquiring real-time three-dimensional contour data of the surface to accurately calculate its flatness index. Some existing laser scanning flatness testers on the market have their laser scanning and receiving systems directly exposed to ambient light. However, changing light sources such as workshop lighting and sunlight entering through windows will act as "noise" superimposed on the laser signal, causing the measurement data to be distorted.

A ball bearing body is movably embedded at equal intervals at the bottom of the auxiliary cover, and multiple flexible rubber strips are also installed at equal intervals along the edge of the auxiliary cover. Multiple magnet blocks are fixedly installed at equal intervals on the lower part of the outer wall of the fixed cover, and C-shaped connectors are slidably arranged on the magnet blocks. On the upper part of the outer wall of the movable cover and at the corresponding magnet block, a magnet block with the opposite polarity to the magnet block is fixedly installed, and the fixed cover and the movable cover are limited by the C-shaped connectors.

[0005] Furthermore, in a preferred configuration, the C-type connector includes a sliding plate and a limiting plate. T-shaped guide blocks are fixedly installed on the adjacent surfaces of the sliding plate and the limiting plate. A connecting plate is fixedly installed between the sliding plate and the limiting plate on the side away from the first magnet block. A guide groove for sliding the T-shaped guide block is provided inside the first magnet block at the corresponding T-shaped guide block.

[0006] In addition, a preferred structure is that the bottom of the second magnet block has a guide groove for the T-shaped guide block to pass through at the corresponding T-shaped guide block.

[0007] In addition, a preferred structure is that a magnet cover is fixedly installed on the side of the movable cover away from the auxiliary cover, and a movable cavity is opened in the fixed cover at the location of the movable cover.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figure 1-4The flatness testing device for aluminum composite panels includes a flatness testing device body 1, which includes a worktable 11. A laser testing mechanism 12 is mounted on the worktable 11, and a light-shielding component 2 is mounted on the outside of the laser testing mechanism 12. It is worth noting that the specific structure, connection method, and working principle of the flatness testing device body 1, the worktable 11, and the laser testing mechanism 12 are all existing technologies that are currently publicly available on the market, so they will not be described in detail.

[0015] The light-shielding component 2 includes a fixed cover 21 and a movable cover 22. One end of the movable cover 22 is vertically slidably disposed inside the fixed cover 21, and an auxiliary cover 221 is fixedly connected to the bottom of the movable cover 22. A ball bearing body 222 is movably embedded at equal intervals at the bottom of the auxiliary cover 221, and multiple flexible rubber strips 223 are also installed at equal intervals along the edge of the auxiliary cover 221. The ball bearing body 222 enables rolling friction between the auxiliary cover 221 and the aluminum composite plate, preventing scratches on the top of the aluminum composite plate. At the same time, the flexible rubber strip fills the gap between the bottom of the cover and the surface of the aluminum plate to a certain extent, forming a soft seal to prevent the intrusion of external ambient light.

[0016] Multiple magnet blocks 211 are fixedly installed at equal intervals on the lower part of the outer wall of the fixed cover 21, and C-shaped connectors 212 are slidably arranged on the magnet blocks 211. A magnet block 225 with opposite polarity to the magnet blocks 211 is fixedly installed on the upper part of the outer wall of the movable cover 22 at the corresponding magnet blocks 211, and the fixed cover 21 and the movable cover 22 are limited by the C-shaped connectors 212.

[0017] The C-type connector 212 includes a sliding plate and a limiting plate. T-shaped guide blocks 213 are fixedly installed on the adjacent surfaces of the sliding plate and the limiting plate. A connecting plate is fixedly installed between the sliding plate and the limiting plate on the side away from the magnet block 211. A guide groove for sliding the T-shaped guide block 213 is opened in the magnet block 211 at the corresponding T-shaped guide block 213.

[0018] The bottom of the magnet block 225 is provided with a guide groove for the T-shaped guide block 213 to pass through at the corresponding T-shaped guide block 213.

[0019] A magnetic cover 224 is fixedly installed on the side of the movable cover 22 away from the auxiliary cover 221, and a movable cavity is opened inside the fixed cover 21 at the location of the movable cover 22.

[0020] The inner wall of the active cavity on the side away from the auxiliary cover 221 is provided with a magnetic layer with the opposite polarity to that of the magnet cover 224. The magnetic layer, the magnet cover 224, and the first and second magnet blocks are all treated with anti-corrosion measures.

[0021] The fixed cover 21 is fixedly fitted onto the outside of the laser detection mechanism 12.

[0022] Furthermore, the inner walls of the housing components are all coated with matte black paint. It is also worth noting that the specific structure, connection method, and working principle of the flatness testing device body 1, the worktable, and the laser testing mechanism are all based on commercially available aluminum plate laser scanning flatness testers, and therefore will not be elaborated upon further.

[0023] In this embodiment, the aluminum composite plate to be tested is placed on the workbench 11, and the auxiliary cover 221 is held in hand. The C-shaped connector 212 is moved away from the magnet block 225 until the C-shaped connector 212 is located on one side of the magnet block 225. Then the auxiliary cover 221 is held in hand and moved towards the top of the aluminum composite plate until its ball bearing body presses against the aluminum composite plate.

[0024] Then, the flatness of the top of the aluminum composite panel is tested by the laser detection mechanism 12. A closed dark room is formed between the laser detection mechanism and the aluminum composite panel to be tested by the light shielding component to reduce the interference of external ambient light.

[0025] After the test is completed, hold the auxiliary cover 221 and move it towards the fixed cover until it can no longer move. At this time, its magnetic cover is magnetically attracted to the inner wall of the movable cavity. Then, hold the C-shaped connector and move it towards the second magnet 225 until its support plate is at the bottom of the second magnet, and its corresponding T-shaped guide block is inserted into the corresponding guide groove, thereby completing the connection between the movable cover and the auxiliary cover and the fixed cover, so as to replace the aluminum composite plate to be tested later.

[0026] In this invention, the flatness of the top of the aluminum composite panel is detected by the laser detection mechanism 12 in the flatness detection device. At the same time, a light-shielding component forms a closed dark room between the laser detection mechanism and the aluminum composite panel to be tested, reducing the interference of external ambient light.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
