Detailed implementation manners
[0024] To make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.
[0025] As Figures 1-8 shown, a phase light detection device for vehicle-mounted silk-screened glass covers proposed by the present utility model mainly includes a protective installation outer frame 1, an FFU cleaning unit 2, an operation table 10, a double-rotor linear motor module 3, a detection carrier 4 and a mobile detection component 9;
[0026] The protective installation outer frame 1 serves as the external support structure of the entire device. The FFU cleaning unit 2 is installed on its top to provide a clean working environment inside the device. The operation table 10 provided on one outer wall is used for operating and controlling the device;
[0027] A pair of dual-rotor linear motor modules 3 are installed on the inner bottom plate of the protection and installation outer frame 1. The detection carrier 4 is movably arranged on the dual-rotor linear motor module 3. The dual-rotor linear motor module 3 is drivingly connected to the support chassis 40, and can drive the detection carrier 4 to move linearly.
[0028] A rotating frame 43 is movably arranged in the support chassis 40 of the detection carrier 4. The first rotary servo motor 41 on the outer wall of a support rod on one side of the support chassis 40 is connected to one end of the rotating frame 43 through the first rotary shaft reducer 42, so as to drive the rotating frame 43 to rotate. The second rotary servo motor 44 on the outer wall of one side of the rotating frame 43 is connected to the width adjustment assembly 5 through the second rotary shaft reducer 45.
[0029] One end of the fixed plate 51 of the width adjustment assembly 5 is arranged at the output end of the second rotary shaft reducer 45, and the other end is movably arranged on the rotating frame 43. A bidirectional lead screw 53 is movably arranged between a pair of bearing seats 50 on the fixed plate 51. The knob 56 at one end of the bidirectional lead screw 53 can be used to adjust the rotation of the lead screw. A pair of fixed rods 54 on the bidirectional lead screw 53 are movably arranged on a pair of first guide rails 52 on the fixed plate 51 through the sliders one 55 at both ends of the bottom. A convex bracket 6 is arranged at the top of one group of fixed rods 54, and a concave bracket 7 is arranged at the top of the other group of fixed rods 54. A plurality of vacuum adsorption holes 8 at the tops of the concave bracket 7 and the convex bracket 6 are connected to a vacuum pump for adsorbing and fixing the arc glass cover plate.
[0030] The linear motor drive module 91 in the mobile detection assembly 9 is arranged in the protection and installation outer frame 1. A second guide rail 93 is arranged on the inner wall of one side of the protection and installation outer frame 1. The linear motor drive module 91 drives the moving plate 92 to move. The slider two 94 at the bottom of one side of the moving plate 92 is slidably arranged on the second guide rail 93. The lifting electric cylinder 95 arranged downward at the top of the moving plate 92 can drive the telescopic rod to drive the phase light imaging module 90 at the top to move up and down after passing through the moving plate 92. A plurality of guide rods 97 at the top of the phase light imaging module 90 are movably arranged in a corresponding plurality of guide sleeves 96 at the top of the moving plate 92 to play a guiding role.
[0031] When using this device, first, it is necessary to determine whether to rotate the handle 56 forward or backward according to the width of the arc-shaped glass cover plate. By rotating the handle 56, the two fixed rods 54 can be adjusted to move inward or outward simultaneously. After adjusting them to the appropriate width, place the arc-shaped glass cover plate on the two convex brackets 6. Then, turn on the vacuum pump for evacuation. At this time, several vacuum adsorption holes 8 will adsorb and fix the cover plate. Subsequently, start the lifting electric cylinder 95 of the top moving detection component 9 to lower the phase light imaging module 90, which will take pictures and detect the arc-shaped glass cover plate. Then, turn on the linear motor drive module 91 to drive the moving plate 92 to move forward. When it moves to both ends of the arc-shaped glass plate, the two ends of the arc-shaped glass cover plate can be rotated to directly below the phase light imaging module 90 for taking pictures and detection by rotating the second rotary servo motor 44 forward or backward;
[0032] After the detection is completed, reset all components. Then, rotate the first rotary servo motors 41 of the two detection carriers 4 in opposite directions to rotate the rotating frame 43 by 90 degrees. Then, by controlling the double-rotor linear motor module 3, move the two support chassis 40 synchronously inward until the convex brackets 6 fit against the arc-shaped glass cover plate and then stop. Subsequently, turn on the vacuum pump of the concave bracket 7 and turn off the vacuum pump of the convex bracket 6 at the same time, so that the arc-shaped glass cover plate can be transferred to another detection carrier 4. After that, reset the device and take pictures and detect the other side of the arc-shaped glass cover plate according to the above steps, thus completing the automatic detection of both sides of the arc-shaped glass cover plate.
