Description

Technical Field

[0001] The utility model relates to the technical field of gloss measuring instruments, in particular to a contact and non-contact dual-purpose gloss meter. Background Art

[0002] Glossmeter is an optical instrument used to measure the glossiness of the surface of an object in a digital way. The contact glossmeter needs to press the measuring port against the surface of the object to be measured. With the gradual application of automated online testing, non-contact glossmeters have emerged. When measuring, they are suspended above the conveyor belt to keep a fixed distance between the measuring port and the surface of the object to be measured. For example, the continuous movement of plates and coils on the conveyor belt is not affected.

[0003] However, in the early stage of automated application, such as for comparison with standard samples or data comparison with other instruments, and small batch sample debugging, contact measurement is still required in these cases, and non-contact gloss meter is difficult to achieve. Therefore, the problem of switching between the early debugging verification and the later automated online detection application scenarios of gloss meter needs to be solved urgently. Utility Model Content

By setting a magnetic measuring bracket according to the non-contact measuring distance of the gloss meter, the measuring bracket is installed during contact measurement, and the measuring bracket is removed during non-contact measurement to keep the surface of the measuring port at a specified non-contact distance, thereby realizing a contact and non-contact dual-purpose gloss meter. The contact measurement mode and the non-contact measurement mode are conveniently switched, which greatly facilitates the user's switching between the early debugging verification and the later automated online detection application scenarios.

[0005] In order to achieve the above purpose, the following technical solutions are adopted:

Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

The utility model designs a magnetic measuring bracket 1 according to the non-contact measurement distance of the gloss meter, that is, the thickness of the measuring bracket 1 is equal to the distance between the surface of the measuring port 5 and the surface of the measured object 11 during non-contact measurement. The measuring bracket 1 is installed during contact measurement, and the measuring bracket 1 is removed during non-contact measurement to keep the surface of the measuring port 5 at a specified non-contact distance, thereby realizing a contact and non-contact dual-purpose gloss meter. When the instrument needs to be calibrated, the measuring bracket 1 is first installed, and then the calibration standard plate 3 is installed to perform calibration, which is more convenient for regular calibration after automated application.

[0033] The utility model provides a contact and non-contact dual-purpose gloss meter, which integrates the contact measurement mode and the non-contact measurement mode of the gloss meter. The two modes are easy to switch, effectively solving the problem of users switching between early debugging and verification and later automated online detection application scenarios. After actual measurement and comparison, the test data of the contact measurement mode and the non-contact measurement mode are basically consistent under indoor natural light. If there is a strong light source directly shining on the surface of the object to be measured indoors, the non-contact measurement mode can be properly shielded to block the light.

[0034] Wherein, the first magnetic attraction component 4 and the second magnetic attraction component 5 both include a magnetic attraction positioning column and a magnetic attraction block matching the magnetic attraction positioning column.

[0035] The instrument body 2 is provided with a first positioning groove corresponding to each first magnetic component 4, and the magnetic block of each first magnetic component 4 is embedded in a first positioning groove for installation and fixation; the magnetic positioning column of the first magnetic component 4 can extend into the corresponding first positioning groove and be adsorbed and fixed to the magnetic block.

In this embodiment, two second magnetic components 6 are provided, which are respectively placed on the opposite outer sides of the measuring through hole. In the second magnetic component 6, the magnetic positioning column is installed on the calibration standard plate 3. By cooperating with the second positioning groove and the magnetic block therein, the calibration standard plate 3 can be aligned and adsorbed on the measuring bracket 1, and the instrument calibration work can be carried out.

[0037] Furthermore, the magnetic block uses a magnet, and the magnet is placed at the bottom of the first positioning groove and the second positioning groove. When the measuring bracket 1 needs to be installed, the measuring bracket 1 is aligned and brought close to each other, and under the action of the magnetic force, the magnetic positioning column cooperates with the magnet to automatically align and adsorb and fix. Similarly, when the calibration standard plate 3 needs to be installed, the calibration standard plate 3 is aligned and brought close to each other, and under the action of the magnetic force, the magnetic positioning column cooperates with the magnet to automatically align and adsorb and fix.

[0038] The instrument body 2 includes a housing 21, and a light source optical path 22 and a receiving optical path 23 arranged in a mirror image in the housing 21; according to the glossiness-related standards, the light source optical path 22 emits a standard light beam at a certain angle to illuminate the surface of the object 11 to be measured through the measuring port 5, and receives the light reflected from the surface of the object 11 to be measured at a mirror angle through the receiving optical path 23, and the received light signal is processed to obtain the glossiness value. A plurality of mounting holes 7 are provided on the side of the housing 21 for external mounting and fixing. Specifically, the mounting holes 7 are set as screw holes, and the instrument can be installed on the automated detection line through the mounting holes 7.

The display screen 8 is used to display the glossiness value of the object 11 to be measured, and the button 9 can be used for related settings, calibration, manual measurement and other operations. The USB port 10 can be connected to PC software or to the data of the automation equipment. After the measuring bracket 1 and the calibration standard plate 3 are disassembled, the non-contact measuring distance between the surface of the measuring port 5 and the surface of the object 11 to be measured is adjusted, and the instrument is connected to the automation equipment via the USB data cable through the USB port 10 for communication, and non-contact automated online detection can be performed.
