Working principle: before trademark detection, three-dimensional information of a trademark is firstly input into image analysis software, then when the trademark is required to be detected, the trademark is installed on a fixed part, a controller is enabled to drive a first tripod head motor 11 and/or a second tripod head motor 12 and/or a rolling motor of a rolling driving component to rotate by operating keys of a key area 5, the trademark 1 fixed on the fixed part is enabled to change angles, images of different angles of the trademark 1 are captured through a camera 2 and compared with model parameters of the trademark 1, whether the shape of the trademark 1 is qualified or not is judged, and a result is displayed on a rear end display area 4.
When the trademark is installed, the part of the three-dimensional trademark is clamped between clamping plates of one positioning assembly firstly from one side of the annular shell 9 away from the camera 2, then the trademark 1 is rotated to enable other positions of the trademark to push the trigger part 22 of the positioning adjusting rod 20, the positioning adjusting rod 20 is contracted towards the inside of the annular shell 9, and after the trademark 1 is positioned at the positioning part 21, the positioning parts 21 of the two positioning adjusting rods 20 clamp and fix the trademark in the middle under the action of the reset spring 46.
When the positioning adjusting rod 20 is contracted towards the inside of the annular shell 9, the driving track groove is arranged at the left and right sides, so that the driving head drives the driving tube 41 to rotate forwards, the seventh bevel gear 33 drives the sixth bevel gear 31 and the third rotating shaft 32 to rotate, at the moment, the first ratchet disc 35 and the first clamping gear ring do not limit rotation mutually, and the second ratchet disc 36 and the second clamping gear ring do not limit rotation mutually. When the return spring 46 returns to the left and right, the driving tube 41 does not rotate, and at this time, the driving rod 45 of the driving head rotates to be not matched with the driving track groove until the driving head moves into the first annular groove 47, and then the driving rod 45 returns to the left and right under the torsion spring. Since the rotation axis of the driving rod 45 has an angle with the helix angle of the helical groove 48, the driving head does not rotate when moving in the helical groove 48.
When the adjusting trademark rotates along the third axis, no matter how the second pan-tilt motor 12 rotates, that is, under the cooperation of the first rotating shaft 27, the third bevel gear 26, the second rotating shaft 29, the fourth bevel gear 28, the third rotating shaft 32, the fifth bevel gear 30, the first ratchet disc 35 and the second ratchet disc 36, the third rotating shaft 32 rotates unidirectionally, no matter the flexible shaft 25 rotates forward or rotates reversely, so that the sixth bevel gear 31 can only rotate unidirectionally, and therefore the driving tube 41 rotates forward, and the positioning adjusting rod 20 is driven to release the clamping of the trademark. So that the trademark changing angle is not affected by the acting force of the positioning adjusting rod 20 at all times, and the adjusting error is avoided.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and those skilled in the art should appreciate that the technical scheme and the inventive concept according to the present invention are equivalent or changed within the scope of the present invention.
