Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1 and fig. 2, the dock of the present invention includes a housing 1 having an accommodating cavity, a scan port 11 is disposed at a front end of the housing 1, and the dock further includes a lens assembly and a scan module 4 sequentially disposed from the scan port 11 toward the accommodating cavity.
Further, the lens subassembly includes first lens 2 and the second lens 3 that mutual interval set up, and the image of sweeping the pier scanning is through first lens 2 and the formation of image of second lens 3 on the camera lens of scanning module 4. According to the invention, the first lens 2 and the second lens 3 which are mutually spaced are sequentially arranged at the scanning port 11 towards the accommodating cavity of the shell 1, and an image scanned by the scanning head is imaged on the lens of the scanning module 4 through the first lens 2 and the second lens 3, so that the scanning head has the function of a single-layer lens code scanning gun, has an explosion-proof function, is suitable for high-risk environments such as gas stations, underground mines, mining fields and the like, and has strong adaptability and flexibility.
In one embodiment of the present invention, the second lens 3 is perpendicular to the axis of the lens, and the first lens 2 and the second lens 3 are disposed at an angle. Preferably, the included angle between the first lens 2 and the second lens 3 is 22.6 °, and the code scanning performance of the code scanning head is best, which is embodied in that the code scanning distance, the recognition probability, the response efficiency and the like are relatively ideal. It should be noted that the setting range of the included angle between the first lens 2 and the second lens 3 is related to whether the surfaces of the first lens 2 and the second lens 3 are coated, the number of the coated surfaces, and the distance between the lens and the scanning module 4. For example, when only one side of the first lens 2 and the second lens 3 is coated with the AR film, the minimum value of the included angle between the first lens 2 and the second lens 3 decreases with the increase of the distance between the lens and the lens of the scan module 4, and when the distance between the lens and the lens of the scan module is 25mm, the minimum value of the included angle between the first lens 2 and the second lens 3 is 32 °.
