Therefore, it should not be understood as a limitation on the present invention.

[0018] In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0019] See also Figure 1 As shown, an embodiment of the utility model provides a non-contact angle detection device, including a base plate 1, a bracket 2 is fixedly installed on the top of the base plate 1, a light source 3 is installed on one side of the top of the bracket 2, and a tilted No. 1 reflector 4 is installed on the other side of the top of the bracket 2. A manually adjustable angle table 5 is also installed on the top of the base plate 1. The manually adjustable angle table 5 uses an existing product available on the market. A No. 2 reflector 8 is installed on the working surface 52 of the manual adjustable angle table 5. The working surface 52 can be driven to deflect by rotating the hand wheel 51, and the No. 2 reflector 8 follows the deflection of the working surface 52, thereby adjusting the angle of the No. 2 reflector 8.

[0020] A telescopic rod 6 is installed on one side of the base plate 1, and a vertically arranged standard part 7 is fixedly installed on the end of the telescopic rod 6 away from the base plate 1. The position of the standard part 7 relative to the No. 1 reflector 4 can be adjusted by extending and retracting the telescopic rod 6 to ensure that the light emitted by the light source 3 can be reflected to the surface of the standard part 7 through the No. 2 reflector 8 and the No. 1 reflector 4 in sequence.

[0021] In one embodiment, the telescopic rod 6 includes a front rod 61, a rear rod 62 and a boat-shaped bolt 63. One end of the front rod 61 is fixedly installed on the side of the base plate 1, and the other end of the front rod 61 is movably inserted into the rear rod 62. One end of the rear rod 62 away from the front rod 61 is fixedly installed with a standard part 7, and the boat-shaped bolt 63 is arranged on the rear rod 62.

[0022] When the boat-shaped bolt 63 is loosened, pushing the rear section rod 62 toward the direction closer to the base plate 1 can make the standard part 7 closer to the No. 1 reflector 4, and pulling the rear section rod 62 toward the direction away from the base plate 1 can make the standard part 7 farther away from the No. 1 reflector 4, thereby adjusting the position of the standard part 7 relative to the No. 1 reflector 4. After adjusting to the appropriate position, tighten the boat-shaped bolt 63 to fix the front section rod 61 and the rear section rod 62 together.

[0023] Furthermore, in one embodiment, a vertical rod 64 is fixedly mounted on one end of the rear section rod 62 away from the front section rod 61 , and the standard component 7 is detachably fixedly mounted on the side of the vertical rod 64 , so as to facilitate the installation and replacement of the standard component 7 .

[0024] Furthermore, in one embodiment, the bracket 2 includes a vertical beam 21 and a horizontal beam 22, the vertical beam 21 is vertically arranged on the top of the base plate 1, and the horizontal beam 22 is horizontally arranged at the top of the vertical beam 21, the light source 3 and the first reflector 4 are respectively arranged on the opposite sides of the horizontal beam 22, and a triangular block 23 with a downward inclined surface is installed on one side of the horizontal beam 22, and the first reflector 4 is arranged on the inclined surface of the triangular block 23, and the inclination angle of the inclined surface of the triangular block 23 is 45°.

[0025] During installation, first fix the manual adjustment angle table 5 on the base plate 1, and install the second reflector 8 on the working surface 52 of the manual adjustment angle table 5, then install the light source 3 and the first reflector 4 on both sides of the beam 22 of the bracket 2 in turn, and finally install the standard part 7 on the vertical rod 64.

[0026] After installation, start the light source 3. The light of the light source 3 is emitted from the upper end to the horizontally placed No. 2 reflector 8, and is reflected by the No. 2 reflector 8 to the No. 1 reflector 4 at an angle of 45° above, and is reflected from the No. 1 reflector 4 to the standard part 7 to form a light spot. Adjust the front and rear positions of the standard part 7 so that the light spot is aligned with the 0° scale on the standard part 7. Manually rotate the hand wheel 51 to rotate the work table 52 on the manual angle adjustment table 5 by 0.1°, and the light spot on the corresponding standard part 7 needs to be offset by 0.1°. If the light spot on the standard part 7 is offset too small, adjust the telescopic rod 6 to extend the standard part 7 to move the standard part 7 backward until the light spot on the corresponding standard part 7 is offset by 0.1°; if the light spot on the standard part 7 is offset too large, adjust the telescopic rod 6 to shorten the standard part 7 to move the standard part 7 forward until the light spot on the corresponding standard part 7 is offset by 0.1°. Similarly, calibrate 0.1°, 0.2°, 0.3°, 0.4°, 0.5°, etc. in sequence, and calibrate according to actual needs.

[0027] After calibration, the measuring piece (product) is placed on the second reflector 8 and aligned with the light spot of the light source 3. The standard piece 7 shows a corresponding angle change, which is the angle of the product. This can detect whether the reflection angle of the measuring piece exceeds the standard.

[0028] In summary, the present application provides a non-contact angle detection device with a simple structure, which can screen products with angles exceeding the standard at the front end and better control the rear-end coupling efficiency and finished product yield.

[0029] This application can better detect product angle problems, avoid contact, and reduce product contamination. At the same time, the accuracy is improved to 0.1°, providing reliable data for subsequent inspections. It can achieve high-precision detection of non-contact angles and help the back-end improve the imaging quality and performance stability of the optical system.

[0030] The above detailed description of the preferred embodiments of the utility model should not be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
