[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] In the description of the present invention, it should be noted that the terms "vertical", "up", "down", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] See also Figure 1-2 The present invention provides a technical solution: a flatness detection device for surface treatment of aluminum-magnesium alloy plate, comprising a detection platform 1; support columns 2 are installed on the left and right sides of the detection platform 1, a detection frame 3 is installed on the top of the support column 2, and a lifting mechanism is connected to the left and right sides of the detection frame 3; a transverse electric slide rail is installed on the detection frame 3, a transverse electric slider 4 is installed on the transverse electric slide rail, and a detection structure for detecting the flatness of the plate is installed on the transverse electric slider 4;

[0020] The detection structure includes a driving rod 5 installed on the lower surface of the transverse electric slider 4 and a detection roller 6 arranged at the bottom of the driving rod 5; the left and right sides of the detection roller 6 are movably connected with rotating shafts, and the ends of the two rotating shafts away from the detection roller 6 are movably connected with limit baffles 7, and the tops of the two limit baffles 7 are connected with arc-shaped detection baffles 8; a plurality of pressure sensors 9 are installed on the side of the detection baffle 8 opposite to the detection roller 6; a plurality of sensor identification parts 10 are installed at equal intervals on the four sides of the baffle plate to be detected along the side direction of the plate to be detected, and the sensor identification parts 10 and the pressure sensors 9 are connected through wireless signal transmission.

[0021] Furthermore, the pressure sensor 9 is electrically connected to a warning light 11 and a buzzer 12 .

[0022] Furthermore, the pressure sensor 9 and the sensor identification element 10 are both connected to a PLC controller via wireless signal transmission.

[0023] Furthermore, the lifting mechanism includes a longitudinal slide groove 13 installed at the top of the support column 2, a transmission screw 14 is installed inside the longitudinal slide groove 13, a lifting slider 15 is threadedly connected to the transmission screw 14, the lifting slider 15 is connected to the detection frame 3, and a transmission motor 16 is installed at the top of the transmission screw 14.

[0024] Furthermore, a plate positioning and locking structure 17 for limiting the position of the baffle plate to be detected is installed on the detection platform 1 below the detection structure, and the plate positioning and locking structure 17 is connected to a driving mechanism.

[0025] Working principle: Before using the present invention, the operator turns on the power supply, and then places the baffle plate to be detected on the detection platform 1, and then drives the positioning and locking structure 17 through the driving mechanism to position and lock the plate, and then starts the two transmission motors 16 on the left and right sides of the detection frame 3 at the same time. The transmission motor 16 drives the transmission screw 14, so that the transmission screw 14 drives the detection frame 3 and the detection structure on the detection frame 3 to a suitable position through the lifting slider 15. The horizontal electric slide 4 and the detection structure on the horizontal electric slide 4 are driven to a suitable position through the horizontal electric slide rail.

[0026] Then, the detection roller 6 at the bottom of the driving rod 5 is driven by the horizontal electric slider 4 through the driving rod 5 to make a reciprocating rolling motion on the surface to be detected of the plate. During the rolling process, the detection roller 6 generates pressure on the detection baffle 8, so that the pressure value of the pressure sensor 9 on the detection baffle 8 changes. When the surface of the plate is uneven, the corresponding detection result of the pressure sensor 9 changes significantly. At the same time, the pressure sensor 9 sends the detection signal to the sensor identification part 10. When the sensor identification part 10 receives the signal from the pressure sensor 9, it marks the specific station of the plate detection. The operator can view the detection result of the specific station of the plate through the marking result of the sensor identification part 10, and then judge the specific station to be processed on the surface of the plate, and then perform targeted surface treatment or process improvement on the plate, which is more practical. When the detection parameters of the pressure sensor 9 do not meet the detection standards, the alarm light 11 can more intuitively feedback the detection results through different light colors and the buzzer 12.

[0027] It is worth noting that the entire device is controlled by a PLC controller. Since the equipment matched with the PLC controller is a commonly used equipment and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
