[0032] The color correction module includes a color correction block 15 and a second mounting block 14. The color correction block 15 is mounted on the second mounting block 14. The color correction block 15 is arranged close to the jig 26. The second mounting block 14 is connected to a second cylinder mounted on the second mounting base 45. Driven by the second cylinder, the color correction module moves up and down simultaneously with the jig 26.

[0033] like Figure 4 、 5As shown, the upper end surface of the moving block 21 is provided with a scanner 28 bracket, and the scanner 28 bracket is a 7-shaped plate 40.

The moving block 21 is provided with a plurality of first bolt holes arranged in a straight line from left to right. The 7-shaped plate 40 is connected to the moving block by passing the bolt through the first rectangular hole 29 and the first bolt hole. The 7-shaped plate 40 is connected to the scanner mounting plate 20 by passing the bolt through the second rectangular hole 17, and the length of the first rectangular hole 29 and the second rectangular hole 17 is greater than the length of the bolt. The outer diameter facilitates the 7-shaped plate 40 to move forward, backward, left and right to adjust its position, and facilitates the scanner mounting plate 20 to move up and down to adjust its position; the scanner mounting plate 20 is provided with a fixing hole 18 and an arc hole 19, and the scanner 28 is fixed to the scanner mounting plate 20 by bolts passing through the fixing hole 18 and the arc hole 19 respectively, and the position of the bolt on the arc hole 19 can be changed, which is convenient for adjusting the angle of the scanner 28 and suitable for different scanning angles; therefore, the scanner 28 can be moved and adjusted on the moving block 21 in the front and back, left and right, up and down, and even the scanning angle can be adjusted.

[0034] like Figure 6 、 7As shown, the colorimeter module 3 includes a spectrophotometer 31, which is fixedly connected to a mounting bracket 33 fixed to the upper end surface of the electrical cabinet 1 through a fastening bracket 32. There are two fastening brackets 32, which are respectively located at the upper and lower ends of the spectrophotometer 31 to clamp and fix the spectrophotometer 31. A first test aperture 35 and a second test aperture 49 are provided below the spectrophotometer 31, wherein a square hole is provided in the middle of the first test aperture 35 for testing the logo on the product 30, and a round hole is provided in the middle of the second test aperture 49 for testing the product 30, and the area of ​​the round hole is larger than that of the square hole, which is convenient for more comprehensive testing of the product 30. The first test aperture 35 and the second test aperture 49 are detachably mounted on the second bracket 38. The second bracket 38 is connected to the third cylinder 34 through the third bracket 37. The third cylinder 34 is fixed on the third mounting plate. The mounting plate is slidably connected to the mounting support base 36 fixed on the mounting bracket 33, that is, the mounting support base 36 is provided with a slide rail, and the third mounting plate is slidably connected to the slide rail. The lower end of the third mounting plate is provided with a fourth cylinder 16 and a support block 48. Driven by the third cylinder 34 and the fourth cylinder 16, the first test aperture 35 and the second test aperture 49 can be moved left and right and up and down to adjust their positions below the spectrophotometer 31. Moreover, when the third mounting plate is moved upward when the fourth cylinder is not in operation, the third mounting plate abuts against the support block 48, thereby preventing the third mounting plate from abutting against the fourth cylinder for a long time and affecting its service life. One end of the second bracket 38 is fixed to the third bracket 37 by a bolt, and the other end is provided with an opening and closing mouth. Connecting ears 39 are respectively provided on both sides of the opening and closing mouth. The two connecting ears 39 are connected by bolts to facilitate the replacement of the first test aperture 35 and the second test aperture 49.

[0035] The working principle of the present invention is:

[0036] like Figure 1-7As shown, first, the product 30 is placed on the fixture 26 and calibrated with the height calibration block 27 to ensure that the height of the product 30 placed on the fixture 26 meets the test requirements. Then, the height calibration block 27 is removed. Under the control of the controller, the barcode scanner 28 scans the product 30. Then, the first motor 44 is started and drives the first screw 43 to rotate, so that the color calibration block 15 and the product 30 pass under the spectrophotometer 31 in sequence. During this process, the third cylinder 34 drives the first test aperture 35 to move to the spectrophotometer 31. The fourth cylinder 16 then drives the first test aperture 35 upwards to approach the spectrophotometer 31. When the color correction block 15 is located directly below the first test aperture 35, the second cylinder drives the color correction block 15 upwards to approach the first test aperture 35 to perform color correction. That is, the spectrophotometer 31 completes color correction when it detects that the color hue, color saturation, brightness, and color uniformity of the color correction block 15 meet the requirements. Then, when the logo on the product 30 moves to the first test aperture 35, the second cylinder drives the color correction block 15 upwards to approach the first test aperture 35 to perform color correction. When the product 30 is directly below the spectrophotometer 31, the first cylinder 24 drives the product 30 upward to approach the first test aperture 35 for testing. The product 30 then moves downward, and the fourth cylinder 16 drives the first test aperture 35 downward. The third cylinder 34 then drives the second test aperture 49 to move to the testing position directly below the spectrophotometer 31. The fourth cylinder 16 then drives the second test aperture 49 close to the spectrophotometer 31. At the same time, the first cylinder 24 drives the product 30 upward to approach the second test aperture 49, allowing the spectrophotometer 31 to test the product 30. During this process, the first motor 44 drives the product 30 to slowly move to the right, allowing it to perform a more comprehensive test on the product 30. After the test is completed, the first cylinder 24 drives the product 30 downward, and the sensor performs positioning testing during this process. After the product 30 and the logo on the product 30 are tested, the first motor 44 reverses, driving the first screw rod 43 to reverse as well, causing the product 30 to move back and return to the bottom of the photoelectric sensor 50. The product 30 is then removed to complete a test.
