Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and in particular relates to a vertical large-caliber vein detector. Background Art

[0002] During the processing and inspection of glass products used in the optical field, some vein stripes are often produced due to the material of the glass itself. These vein stripes will affect the final optical performance of the optical glass product. Therefore, special means are needed to identify them. It is necessary to develop a high-precision vein detector for the detection of extremely difficult slight veins, improve the detection efficiency and stability, and enhance the detection efficiency of the vein detector. Without reducing the detection accuracy, the single-piece detection method can be improved to multi-piece measurement.

[0003] Chinese patent publication number CN102706898A discloses a vein viewer comprising a bracket, an observation platform, and a support. The observation platform is positioned above the bracket, and the support is positioned to one side of the observation platform. A slideway is provided on one side of the support, and a camera, a first collimating lens, a second collimating lens, and a light source are sequentially positioned on the slideway from top to bottom via a fixed block. The camera is connected to a display via a cable, and a zoom lens is positioned below the camera. The center points of the camera, zoom lens, first collimating lens, second collimating lens, and light source are aligned vertically. By adjusting the distance between the light source and the second collimating lens, as well as the distance between the first and second collimating lenses, a map of the veining or surface texture of the sample being inspected can be obtained on the display using the principle of light imaging.

[0004] In actual applications, to facilitate the placement of the inspected object, the placement position is often raised to an appropriate height during the design phase. This, combined with the redundant length required for the light propagation path and the reserved height adjustment, results in a high height for the entire observer. This is not only detrimental to the placement of the observer, but also to its transportation and movement. Summary of the Invention

[0005] In order to overcome the problem that the height of the vein detector in the prior art is often too high, which is not conducive to the placement and transportation of the detector; one purpose of the utility model is to provide a vertical large-aperture vein detector, which, by tilting two reflectors, allows the light emitted vertically upward to enter the camera vertically downward after two reflections, and at the same time, a fine-tuning structure is provided on the reflector to ensure the accuracy of light transmission.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a vertical large-aperture vein detector, comprising a vertically arranged mounting track; the mounting track is sequentially provided with a laser, two plano-convex lenses, and a camera from bottom to top; two reflectors are obliquely provided at the upper end of the mounting track; the two reflectors allow the light emitted upward by the laser to enter downward into the camera; a fine-tuning structure is provided between at least one of the reflectors and the mounting track; the fine-tuning structure comprises three hand screws threadedly connected to the upper end of the mounting track and a spring provided between the mounting track and the corresponding reflector; a ball head is provided at one end of the hand screw facing the reflector; the elastic force of the spring is used to make the reflector and the ball head offset.

[0007] After being reflected and folded, the light emitted by the laser reduces the height of the longitudinal transmission of the light, that is, the overall height of the detector is reduced, making the detector easier to place, arrange, transport and move; at the same time, a fine-tuning structure is provided, and by rotating the three hand screws, the relative angle between the two reflectors is changed, ensuring that the light emitted by the laser enters the camera vertically, thereby improving the accuracy of vein detection.

[0008] Furthermore, a plurality of pin grooves are respectively provided at one end of the mounting plate away from the corresponding reflector and at one end of the reflector away from the mounting plate; each of the pin grooves is evenly distributed between two adjacent hand screws; a through hole is provided in the middle of the pin groove; a pin is provided inside the pin groove; the spring passes through the through hole, and both ends are respectively provided on adjacent pins.

[0009] Specifically, an adjustable aperture is provided on the mounting track above the camera; the laser and the two plano-convex lenses are located in a first vertical axis; the camera and the adjustable aperture are located in a second vertical axis; the first vertical axis and the second vertical axis are staggered with each other; and the two reflectors are respectively located in the first vertical axis and the second vertical axis.

[0010] Specifically, a convex track is longitudinally arranged on the mounting track; mounting parts are respectively provided on the laser, the plano-convex lens, the camera, and the adjustable aperture; the mounting part includes two buckle plates and at least one fastening screw arranged between the two buckle plates; the two buckle plates are clamped on the convex track.

[0011] Furthermore, it also includes a measuring box arranged between the two plano-convex lenses; a plurality of objects to be measured can be placed in the measuring box at the same time; and the objects to be measured are arranged horizontally at intervals.

[0012] Furthermore, a base cabinet is provided at the lower part of the mounting track; an upper cover shell is provided at the upper part of the mounting track; the plano-convex lens located at the lower part is located at the upper end of the base cabinet; the plano-convex lens located at the upper part is located inside the upper cover shell; and the side wall of the upper cover shell is detachably connected with a disassembly plate.

[0013] By removing the disassembly plate, the fine-tuning structure can be easily adjusted, and the positions of the camera, the adjustable aperture, and the plano-convex lens located above can also be adjusted.

[0014] Specifically, a light source adjuster is provided on the mounting track; the light source adjuster is located between the two plano-convex lenses.

[0015] Specifically, cabinet doors are respectively provided on the front and rear sides of the base cabinet; a plurality of Forma wheels are provided at the lower end of the base cabinet; a marble countertop is provided at the upper end of the base cabinet; and the mounting rails are provided on the marble countertop.

[0016] Furthermore, the center of the reflector is opposite to the triangular area formed by the three hand screws; the three hand screws are used to adjust the relative levelness between the reflector and the mounting plate.

[0017] Furthermore, the reflector is provided with three external cut holes which respectively abut against the outer periphery of the corresponding ball head.

[0018] Specifically, a mounting plate is obliquely provided on the upper end of the mounting rail; the hand screws are provided on the mounting plate; the mounting plate is rectangular, and the three hand screws are respectively close to the three corners of the mounting plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. By setting up two reflectors, the light path is folded, thereby reducing the length required for light propagation, that is, reducing the height of the vein detector, making the vein detector easier to place, arrange, and transport.

[0021] 2. By setting up a fine-tuning structure, the relative angle between the two reflectors is fine-tuned to ensure that the light emitted by the laser can enter the camera vertically, preventing slight errors caused during transportation and movement, and ensuring the accuracy of detection.

[0022] 3. By setting up the measuring box, you can choose to perform vein detection on a single or multiple objects at the same time to improve the detection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
