Description

Technical Field

[0001] This invention relates to the field of sheet metal testing devices, specifically a flatness testing device for the surface treatment of aluminum-magnesium alloy sheets. Background Technology

[0002] The surface treatment quality of aluminum-magnesium alloy sheets is a crucial aspect of their overall quality. The appearance quality of aluminum-magnesium alloy sheets not only reflects their protective and decorative properties but is also a significant factor in their product value. Since aluminum-magnesium alloy sheets require surface treatments such as coating during processing, any defects in the sheet's flatness before these treatments can severely impact processing quality and efficiency. Therefore, it is essential to pre-test the flatness of the sheet surface and implement targeted technical improvements and treatments for any substandard workpieces. Summary of the Invention

[0003] The purpose of this invention is to provide a flatness detection device for the surface treatment of aluminum-magnesium alloy plates, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a flatness testing device for surface treatment of aluminum-magnesium alloy plates, comprising a testing platform; support columns are installed on the left and right sides of the testing platform, a testing frame is installed at the top of the support columns, and a lifting mechanism is connected to both the left and right sides of the testing frame; a transverse electric slide rail is installed on the testing frame, a transverse electric slider is installed on the transverse electric slide rail, and a testing structure for testing the flatness of the plate is installed on the transverse electric slider;

[0005] The detection structure includes a drive rod mounted on the lower surface of a transverse electric slider and a detection roller located at the bottom of the drive rod. Rotary shafts are movably connected to the left and right sides of the detection roller, and limit baffles are movably connected to the ends of the two rotating shafts away from the detection roller. Arc-shaped detection baffles are connected to the tops of the two limit baffles. Several pressure sensors are mounted on the side of the detection baffle opposite to the detection roller. Several sensor markers are evenly spaced along the edges of the baffle plate to be detected, and the sensor markers and pressure sensors are connected via wireless signal transmission.

[0006] Preferably, the pressure sensor is electrically connected to an alarm light and a buzzer. When testing the board material, if the detection parameters of the pressure sensor do not meet the detection standards, the alarm light and buzzer can provide more intuitive feedback on the detection results.

[0007] Preferably, both the pressure sensor and the sensor identifier are connected to a PLC controller via wireless signal transmission.

[0008] Preferably, the lifting mechanism includes a longitudinal slide groove installed at the top of the support column, a transmission screw installed inside the longitudinal slide groove, a lifting slider threadedly connected to the transmission screw, the lifting slider being connected to the detection frame, and a transmission motor installed at the top of the transmission screw. The transmission motor drives the transmission screw to rotate, and the threaded structure on the transmission screw drives the lifting slider and the detection frame on the lifting slider to perform vertical linear displacement movements, thereby achieving the purpose of adjusting the height of the detection mechanism.

[0009] Preferably, a plate positioning and locking structure for limiting the plate to be tested is installed on the detection platform below the detection structure, and the plate positioning and locking structure is connected to a drive mechanism for driving the positioning and locking structure.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. This invention uses a detection structure mounted on a detection frame to detect the surface flatness of aluminum alloy sheets. During the detection process, when a workstation is found where the sheet flatness does not meet the actual production requirements, the pressure sensor sends a detection signal to a sensor identifier. When the sensor identifier receives the signal from the pressure sensor, it marks the specific workstation of the sheet. Operators can view the detection results of the specific workstation of the sheet through the markings on the sensor identifier, thereby determining the specific workstation on the sheet surface that needs to be processed, and then carrying out targeted surface treatment or process improvement on the sheet. This invention has strong practicality.

[0012] 2. The present invention has a transverse electric slider and a transverse electric slide rail installed on the testing frame for adjusting the transverse position of the testing structure. A transmission motor, a transmission screw and a lifting slider are installed on the left and right sides of the testing frame for adjusting the height of the testing mechanism. The structure is simple and highly flexible. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0019] Please see Figure 1-2 The present invention provides a technical solution: a flatness detection device for surface treatment of aluminum-magnesium alloy sheet, including a detection platform 1; support columns 2 are installed on the left and right sides of the detection platform 1, and a detection frame 3 is installed on the top of the support columns 2. Lifting mechanisms are connected to both 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 sheet is installed on the transverse electric slider 4.

[0020] The detection structure includes a drive rod 5 mounted on the lower surface of the transverse electric slider 4 and a detection roller 6 located at the bottom of the drive rod 5; the left and right sides of the detection roller 6 are movably connected to rotating shafts, and the ends of the two rotating shafts away from the detection roller 6 are movably connected to limit baffles 7, and the tops of the two limit baffles 7 are connected to arc-shaped detection baffles 8; several pressure sensors 9 are mounted on the side of the detection baffle 8 opposite to the detection roller 6; several sensor markers 10 are evenly spaced along the side of the baffle to be detected, and the sensor markers 10 and the pressure sensors 9 are connected by wireless signal transmission.

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

[0022] Furthermore, both the pressure sensor 9 and the sensor identification element 10 are connected to the 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 installed inside the longitudinal slide groove 13, a lifting slider 15 threadedly connected to the transmission screw 14, the lifting slider 15 being connected to the detection frame 3, and a transmission motor 16 installed at the top of the transmission screw 14.

[0024] Furthermore, a plate positioning and locking structure 17 for limiting the plate to be tested is installed on the detection platform 1 below the detection structure. The plate positioning and locking structure 17 is connected to a drive mechanism.

[0025] Working Principle: Before using this invention, the operator connects the power supply and places the plate to be inspected on the inspection platform 1. The drive mechanism then positions and locks the plate using the positioning and locking structure 17. Simultaneously, the two drive motors 16 on the left and right sides of the inspection frame 3 are activated. These motors drive the lead screw 14, which in turn moves the inspection frame 3 and the inspection structure on it to the appropriate position via the lifting slider 15. The transverse electric slide rail then moves the transverse electric slider 4 and the inspection structure on it to the appropriate workstation.

[0026] Next, the horizontal electric slider 4 drives the detection roller 6 at the bottom of the drive rod 5 to reciprocate on the surface of the board to be inspected via the drive rod 5. During the rolling process, the detection roller 6 exerts pressure on the detection baffle 8, causing the pressure value of the pressure sensor 9 on the detection baffle 8 to change. When the surface of the board is uneven, the detection result of the corresponding pressure sensor 9 changes significantly. At the same time, the pressure sensor 9 sends the detection signal to the sensor identification component 10. When the sensor identification component 10 receives the signal from the pressure sensor 9, it marks the specific work station of the board inspection. The operator can view the detection result of the specific work station of the board through the marking result of the sensor identification component 10, and thus determine the specific work station to be processed on the board surface, and then carry out targeted surface treatment or process improvement on the board, which is highly practical. When the detection parameters of the pressure sensor 9 do not meet the detection standards, the alarm light 11 can provide more intuitive feedback on the detection result 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 common device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
