[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figures 1-3 , a simple distance detection device applied to the narrow space of a coating machine includes: a base 1; a benchmark 2, with a detection end 21 and a fixed end 22 at both ends of the benchmark 2, and the fixed end 22 is rotatably mounted on the base 1; an elastic clamping member 4, installed on both sides of the benchmark 2 near the fixed end 22 to elastically clamp the benchmark 2.

[0027] It is understandable that the base 1 is the mounting base of this device. For example, it can be square-shaped, disc-shaped, etc., but not limited to this. The base 1 can be made of stainless steel, aluminum alloy, bakelite, epoxy resin, plastic, etc., but not limited to this. The lever 2 is a component that comes into contact with the object to be measured 6 during the overall rotation of this device and undergoes angular rotation. For example, it can be pointer-shaped, long-rod-shaped, etc., but not limited to this. The elastic clamping member 4 is a component that elastically clamps the lever 2. For example, it can be a spring, a bent elastic piece, elastic rubber, etc., but not limited to this.

[0028] With such a setting, assuming that the distance between the object to be measured 6 and a certain structure is detected, first install the base 1 on the outer wall of this structure, rotate this structure to drive the device to rotate circumferentially, or rotate the device circumferentially along the outer wall of this structure. During the rotation, when the detection end 21 of the lever 2 touches the object to be measured 6, the lever 2 will deflect. Due to the action of the elastic clamping member 4, the lever 2 will be clamped to ensure that the deflection angle of the lever 2 remains unchanged. Then take out this device and measure the distance between the detection end 21 and the rotation axis of the fixed end 22, as well as the distance from the rotation axis of the fixed end 22 to the top surface of the base 1. The sum of the two distances is the distance between the object to be measured 6 and the part. Since the volume of this device is small, the rapid detection of the distance in a narrow space can be realized.

[0029] In some embodiments, the rotation axis of the fixed end 22 is on the same plane as the top surface of the base 1, or is located above the top surface of the base 1. It is understandable that when the rotation axis of the fixed end 22 is located above the top surface of the base 1, it is necessary to measure the distance between the detection end 21 and the rotation axis of the fixed end 22, as well as the distance from the rotation axis of the fixed end 22 to the top surface of the base 1, and calculate the sum of the two distances. When the rotation axis of the fixed end 22 is on the same plane as the top surface of the base 1, the distance between the fixed end 22 and the top surface of the base 1 can be directly measured, and the detection is more rapid.

[0030] In some embodiments, referring to Figure 2 , there is also a connecting shaft 5, and the connecting shaft 5 is rotationally matched with the base 1 and / or the fixed end 22. It is understandable that the connecting shaft 5 is a component for rotatably mounting the fixed end 22. For example, the two ends of the connecting shaft 5 can be rotatably arranged on the base 1, and the fixed end 22 is fixed on the connecting shaft 5; it can also be that the two ends of the connecting shaft 5 are fixed on the base 1, and the fixed end 22 is rotatably sleeved on the connecting shaft 5; it can also be that the connecting shaft 5 is rotationally matched with both the base 1 and the fixed end 22, etc., but not limited to this. In this way, the rotational mounting of the fixed end 22 is realized by using the connecting shaft 5, and the structure is simple and stable. And when the elastic clamping member 4 is a spring, it can be sleeved on the connecting shaft 5 to improve the compactness of the structural cooperation.

[0031] In some embodiments, two spaced crossbeams are detachably mounted on the top surface of the base, and the connecting shaft is mounted between the two crossbeams. Further, a groove is formed on the base below the fixed end 22. The provision of the groove 11 can avoid the fixed end 22 at the bottom of the benchmark 2 and prevent the benchmark 2 from blocking the fixed end 22 during rotation. Of course, when the fixed end 22 is above the base 1, the top surface of the base 1 will not cause contact obstruction to the fixed end 22, and the groove 11 may not be provided. The crossbeam 3 and the base 1 can be installed by sandwiching the two sides of the base 1, or directly installed using fasteners such as screws or bolts, but not limited thereto. Here in the design, the axis of the connecting shaft 5 is set to be flush with the top surface of the base 1, so as to ensure that the rotation axis of the fixed end 22 is flush with the top surface of the base 1. The detachable installation of the crossbeam 3 is convenient for the elastic clamping member 4 to clamp the benchmark 2 during the assembly process.

[0032] In some embodiments, the benchmark 2 is a telescopic structure. It can be understood that the telescopic structure can adopt a telescopic rod structure or a folding structure, etc., but not limited thereto. In this way, during detection, the length of the benchmark 2 can be adjusted according to the length of the detected distance, improving the practicability and accuracy.

[0033] In some embodiments, referring to Figures 3-4 , it further includes a fixing member 7, and the base 1 is mounted on the outer wall of the fixing member 7 to drive the base 1 to perform circular motion or horizontal motion. Further, the top surface of the base 1 is tangent to or flush with the outer wall of the fixing member 7. It can be understood that when detecting the distance between the measured object 6 and a certain structure, the fixing member 7 can be either the structure itself or an externally mounted component. For example, when performing circular motion, referring to Figure 3 , the fixing member 7 can be a roller 9, or a rotating shaft, etc., but not limited thereto. Correspondingly, the top surface of the base 1 is tangent to the outer wall of the fixing member 7. For example, when performing horizontal motion, referring to Figure 4 , the fixing member 7 can adopt a matching structure of a guide rail and a slider or a shaft hole guiding structure of a guide rod and a guide block, etc., but not limited thereto. Correspondingly, the top surface of the base 1 is flush with the outer wall of the fixing member 7. In this way, the distance between the measured object 6 and the fixing member 7 is the distance between the measured object 6 and the top surface of the base 1.

[0034] For example, here an embodiment of the application of this device in a vacuum coating equipment is provided:

[0035] Referring to Figure 1 and Figure 5 , in a vacuum coating equipment, there is a coating cavity 8, a roller 9 in the coating cavity 8, and a measured object 6 on the inner wall of the coating cavity 8. Here, it is necessary to detect the distance between the measured object 6 and the outer wall of the roller 9.

[0036] First, install the base 1 on the outer wall of the drum 9. By rotating the drum 9, the lever 2 is driven to rotate. When the detection end 21 at the top of the lever 2 touches the object to be measured 6, it will deflect. The height to be measured is H, and the actually measured height is the distance h1 between the detection end 21 at the top of the lever 2 and the top surface of the base 1. There is a measurement error ΔH between the height H to be measured and the actually measured height h1.

[0037] It is known that the diameter of the coating chamber 8 is approximately 1650 mm, and the distance between the surface of the object to be measured 6 and the outer wall of the drum 9 is 10 - 20 mm. It is easy to know that the larger the height H to be measured, the larger the measurement error ΔH. According to Hmax ≈ 20 mm, when the height L of the lever 2 is set to be 1.5 times the height H to be measured and 2 times the height H to be measured, it is easy to know that the errors ΔH at this time are 0.31 mm and 0.75 mm respectively.

[0038] When the height L of the lever 2 is selected to be between 1H and 1.5H, the test error ΔH is about 0.00 mm - 0.31 mm. Remove this device, and the actually measured height is h1. Since the height H to be measured is much smaller than the length of the film chamber diameter, the measurement error ΔH is very small and can be ignored. Therefore, the actually measured height h1 can be regarded as the height H to be measured to achieve rapid detection.

[0039] When the height of the lever 2 is greater than 1.5 times the height H to be measured, the telescopic length of the lever 2 can be adjusted so that the height of the lever 2 is between 1 time and 1.5 times the height H to be measured and then test again to reduce the measurement error.

[0040] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
