DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1 As shown, an ink thickness measuring device based on a dual-probe spectral confocal displacement sensor according to an embodiment of the utility model comprises a detection platform 1, a support seat 11, a screw 21, a slider 22 and a motor 23. Two support seats 11 are provided, and the two support seats 11 are respectively located on the left and right sides of the detection platform 1. The screw 21 is provided between the two support seats 11 and is rotatably connected to the two support seats 11. The slider 22 is sleeved on the screw 21. The slider 22 is used to be connected to the dual-probe spectral confocal displacement sensor 3. The motor 23 is provided on the detection platform 1. The output shaft of the motor 23 is connected to the screw 21 and is coaxially distributed.

[0019] In this embodiment, a detection platform 1, a support seat 11, a screw rod 21, a slider 22 and a motor 23 are arranged, and the motor 23 is used to drive the screw rod 21 to rotate, thereby driving the slider 22 to move on the screw rod 21. Since the slider 22 is connected to the dual-probe spectral confocal displacement sensor 3, the dual-probe spectral confocal displacement sensor 3 can be driven to move on the detection platform 1, which is convenient for positioning the dual-probe spectral confocal displacement sensor 3 and the oil cup, so that the dual-probe spectral confocal displacement sensor 3 can accurately measure the ink thickness.

[0020] At the same time, by providing two support seats 11, it is convenient to provide the screw rod 21, ensuring the stability of the transmission of the screw rod 21. By providing the motor 23, the screw rod 21 can be driven to rotate by the motor 23, which is convenient for realizing automatic adjustment.

[0021] Alternatively, if Figure 1 As shown, the ink thickness measuring device based on the dual-probe spectral confocal displacement sensor also includes a track 12, which is arranged on the detection platform 1, and the extension direction of the track 12 is parallel to the axial direction of the screw rod 21. The slider 22 is arranged in the track 12 and is slidably connected to the track 12.

[0022] In this embodiment, by setting a track 12 on the detection platform 1, and setting the extension direction of the track 12 to be parallel to the axial direction of the screw rod 21, and the slider 22 is slidably connected to the track 12, it can be ensured that during the rotation of the screw rod 21, the slider 22 can accurately move along the left and right directions, and the slider 22 is connected to the dual-probe spectral confocal displacement sensor 3, so as to ensure the accuracy of the position adjustment of the dual-probe spectral confocal displacement sensor 3.

[0023] Alternatively, if Figure 1 As shown, the ink thickness measuring device based on the dual-probe spectral confocal displacement sensor also includes a first connecting plate 41 and a first fastening screw 42. The first connecting plate 41 is connected to the support seat 11, and the first fastening screw 42 is rotatably connected to the first connecting plate 41, and the lower end is used to abut against the upper end surface of the detection platform 1.

[0024] In this embodiment, by providing the first connecting plate 41 and the first fastening screw 42, the first fastening screw 42 is vertically arranged, and by tightening the first fastening screw 42 so that the lower end of the first fastening screw 42 abuts against the upper end surface of the detection platform 1, the slider 22 can be positioned to prevent the dual-probe spectral confocal displacement sensor 3 from shifting when measuring the ink thickness. At the same time, loosening the first fastening screw 42 can drive the slider 22 to move, which is convenient for adjusting the position of the dual-probe spectral confocal displacement sensor 3.

[0025] Alternatively, if Figure 1 As shown, the ink thickness measuring device based on the dual-probe spectral confocal displacement sensor further includes a rubber head 43 , and the lower end of the first fastening screw 42 is provided with the rubber head 43 , and the rubber head 43 abuts against the upper end surface of the detection platform 1 .

[0026] In this embodiment, a rubber head 43 is provided at the lower end of the first fastening screw 42, and when the first fastening screw 42 is tightened, the rubber head 43 is used to abut against the upper end surface of the detection platform 1. Compared with directly using the lower end of the first fastening screw 42 to abut against the upper end surface of the detection platform 1, it can reduce the wear of the first fastening screw 42 and the detection platform 1.

[0027] Alternatively, if Figure 1 As shown, the ink thickness measuring device based on the dual-probe spectral confocal displacement sensor also includes a second connecting plate 51 and a rotating shaft. Two second connecting plates 51 are provided. The two second connecting plates 51 are respectively arranged on the left and right sides of the upper end of the support seat 11. The two second connecting plates 51 are both provided with connecting holes. The two ends of the rotating shaft are respectively arranged in the two connecting holes. The rotating shaft is used to sleeve the dual-probe spectral confocal displacement sensor 3.

[0028] In this embodiment, by setting the second connecting plate 51 and the rotating shaft, specifically, the axial direction of the rotating shaft is parallel to the axial direction of the screw rod 21, and the dual-probe spectral confocal displacement sensor 3 is sleeved on the rotating shaft, the dual-probe spectral confocal displacement sensor 3 can be rotated to adjust the angle and height of the dual-probe spectral confocal displacement sensor 3, and further make the dual-probe spectral confocal displacement sensor 3 accurately correspond to the oil cup, which is beneficial for the dual-probe spectral confocal displacement sensor 3 to accurately measure the ink thickness.

[0029] Alternatively, if Figure 1 As shown, the ink thickness measuring device based on the dual-probe spectral confocal displacement sensor also includes a second fastening screw 52, ​​which is rotatably connected to the second connecting plate 51, and the end of the second fastening screw 52 is used to be inserted into the connecting hole and abut against the rotating shaft.

[0030] In this embodiment, by providing a second fastening screw 52 and tightening the second fastening screw 52, ​​the end of the second fastening screw 52 can be used to abut the rotating shaft to limit the rotation of the rotating shaft, that is, the rotation of the dual-probe spectral confocal displacement sensor 3 can be limited, thereby ensuring the stability of the dual-probe spectral confocal displacement sensor 3, so that the dual-probe spectral confocal displacement sensor 3 can accurately measure the ink thickness.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
