Description

Technical Field

[0001] This application relates to the technical field of coating surface detection, and in particular to an automatic sheet inspection device for electroplated sheets. Background Art

[0002] As Figure 1 shown, it is a sheet inspection device for electroplated sheets in the prior art. In the roll-to-roll electroplating industry, it is used to detect abnormal conditions such as dirt, missing plating, and color difference on the surface of the electroplated sheet 20. It mainly consists of a sheet inspection table 10, a fixed shaft 5, and a CCD camera assembly 7. The CCD camera assembly 7 takes pictures of the electroplated sheet 20 below, and then uploads them to the computer system for AOI vision inspection and obtains the inspection results. The length of the sheet inspection table 10 is generally only 30 cm. Since the length of the electroplated sheet 20 to be detected is relatively long, about one meter (the circumference of a selective electroplating mold is about 1 meter, and a whole circle needs to be selected for detection). After being placed on the sheet inspection table 10, both ends droop, the middle is high, and the electroplated sheet 20 is prone to bulge upward, generating an arc-shaped reflective surface, which affects the photographing effect of the CCD camera assembly 7 and the accuracy of the detection. In addition, it is necessary to manually move the electroplated sheet 20 horizontally step by step until the entire surface is detected. Manually moving the electroplated sheet 20 is prone to missed detection and may also cause secondary contamination of the surface of the electroplated sheet 20, which also affects the accuracy of the detection. Summary of the Utility Model

[0024] The following will further describe the present application in detail Figure 2-6 in conjunction with the attached drawings.

[0025] Reference Figure 2 and Figure 3 In the embodiment of the present application, an automatic sheet inspection device for electroplated sheets is disclosed, which includes a sheet placement platform 1, a fixed base 2, an X-axis electric moving platform 3, a Y-axis manual moving platform 4, a fixed shaft 5, a lifting adjustment block assembly 6, and a CCD camera assembly 7. The X-axis electric moving platform 3 is arranged on the fixed base 2, the Y-axis manual moving platform 4 is arranged on the X-axis electric moving platform 3, the fixed shaft 5 is arranged on the Y-axis manual moving platform 4, the CCD camera assembly 7 is arranged on the fixed shaft 5 through the lifting adjustment block assembly 6, and the sheet placement platform 1 is located below the CCD camera assembly 7.

[0026] Reference Figure 6 As shown, a plurality of ventilation grooves 11 are arranged in an array on the sheet placement platform 1. The sheet placement platform 1 is preferably a flat platform, and its length and width dimensions should be larger than the dimensions of the electroplated sheet 20 to be detected, so that the flatness of the electroplated sheet 20 will be very high. The plurality of ventilation grooves 11 have two functions. One is to prevent the electroplated sheet 20 from being adsorbed on the sheet placement platform 1 and being difficult to remove. The other is that a finger can lift the electroplated sheet 20 from the side, which is convenient for adjusting the position of the electroplated sheet 20 and taking away the electroplated sheet 20.

[0027] The CCD camera assembly 7 is connected to a computer system, which is used to take pictures of the electroplated sheet 20 and upload them. The AOI vision detection software in the computer system can perform detection and output results. This belongs to the content of the prior art and will not be elaborated here. The X-axis electric moving platform 3 can drive the Y-axis manual moving platform 4, the fixed shaft 5, the lifting adjustment block assembly 6, and the CCD camera assembly 7 to move horizontally, moving according to the set step distance. Each time it moves one step, a picture is taken, and the corresponding area on the electroplated sheet 20 can be detected. When moving from left to right or from right to left once, the entire area of the electroplated sheet 20 is detected.

[0028] Reference Figure 4 and Figure 5 As shown, the X-axis electric moving platform 3 includes an X-axis horizontal slide 31, a first slide rail and slider assembly 32, and a motor screw drive assembly 33. The X-axis horizontal slide 31 is slidably arranged on the fixed base 2 through the first slide rail and slider assembly 32, and the motor screw drive assembly 33 is also arranged on the fixed base 2, which is used to drive the X-axis horizontal slide 31 to move horizontally along the X-axis. The Y-axis manual moving platform 4 includes a Y-axis horizontal slide 41, a second slide rail and slider assembly 42, and a handwheel screw drive assembly 43. The Y-axis horizontal slide 41 is slidably arranged on the X-axis horizontal slide 31 through the second slide rail and slider assembly 42, and the handwheel screw drive assembly 43 is also arranged on the X-axis horizontal slide 31, which is used to drive the Y-axis horizontal slide 41 to move horizontally along the Y-axis.

[0029] For the same electroplated sheet 20, the height and the front-back position of the CCD camera assembly 7 only need to be adjusted once and then locked. Therefore, a manual operation structure is preferably selected. During the detection process, the CCD camera assembly 7 needs to move dynamically in the left-right direction. Therefore, an electric structure is selected to automatically perform a stepping movement operation under program control.

[0030] In this embodiment, the first slide rail slider assembly 32 is a double slide rail slider assembly, and the second slide rail slider assembly 42 is a double slide rail slider assembly, which improves the moving accuracy and smoothness in the X-axis and Y-axis directions.

[0031] Referring to Figure 4 and Figure 5 , the lifting adjustment block assembly 6 includes a lifting block 61 and a locking set screw 62. The lifting block 61 is provided with a vertical sliding hole and a side screw hole (both not shown). The lifting block 61 is slidably arranged on the fixed shaft 5 through the vertical sliding hole. The locking set screw 62 is arranged in the side screw hole and is used to tighten or loosen the fixed shaft 5 to lock or loosen the lifting block 61. A retaining cap 51 is further provided at the upper end of the fixed shaft 5 to prevent the lifting block 61 from sliding out of the fixed shaft 5.

[0032] The implementation principle of this application is as follows: The CCD camera assembly 7 of the automatic sheet inspection device of this application can be adjusted in three directions of X, Y, and Z. Among them, the height and the front-back position of the CCD camera assembly 7 can be manually adjusted to ensure that a suitable area range and clear pictures can be captured; the X-axis electric moving platform 3 can drive the CCD camera assembly 7 to move left and right. By designing a reasonable step distance, all areas of the electroplated sheet 20 can be automatically detected step by step, greatly reducing the degree of manual participation, making the detection efficiency more stable, and significantly improving the situation of secondary pollution; the length of the sheet placing platform 1 is set to be relatively long, preferably covering the length of the electroplated sheet 20, so that the electroplated sheet 20 can be placed flat on the sheet placing platform 1 without generating an arc-shaped reflective surface, resulting in clearer pictures and higher detection accuracy.

[0033] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
