Description

Technical Field

[0001] This utility model relates to an adjustment bracket, specifically a light source lens adjustment bracket, belonging to the field of machine vision technology. Background Technology

[0002] Linear laser light sources are widely used in the field of machine vision for 2D imaging supplementary lighting. Utilizing the high monochromaticity and good collimation of linear laser light sources in combination with line scan machine vision cameras, detailed features of the subject can be captured with high precision. Since the imaging field of view of a line scan camera is a line on the order of micrometers in width, while the spot of a linear laser light source is a linear spot with a width of 10mm-20mm, the linear laser spot needs to be aligned with the imaging field of view of the line scan camera when providing supplementary lighting. The laser must illuminate the imaging field of view to achieve its supplementary lighting effect; therefore, the method of adjusting and aligning the two is particularly important for 2D machine vision imaging.

[0003] A Chinese utility model patent (publication number: CN206450884U) discloses a linear light source lens adjustment bracket, which controls the up-and-down movement of the linear bearing mounting block by adjusting the fine thread pair; locking the fine thread pair locks the position of the linear bearing mounting block, and with the effect of the front fine thread pair, the light source lens sleeve rotates up and down along the two side shafts, which can play the role of fine adjusting the pitch angle and the height of the output axis.

[0004] Although the device has achieved the function of fine adjustment of the pitch angle of the light source lens and the height of the light source lens exit axis, the process of adjusting the height of the light source lens exit axis will cause the existing pitch angle of the light source lens to change, thus requiring the readjustment of the pitch angle of the light source lens. This repeated adjustment process not only greatly increases the cumbersomeness of operation and reduces the overall efficiency, but may also introduce additional errors during multiple adjustments. Therefore, a light source lens adjustment bracket is proposed. Utility Model Content

[0005] In view of this, the present invention provides a light source lens adjustment bracket to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0006] The technical solution of this utility model embodiment is implemented as follows: a light source lens adjustment bracket includes a base, on which an adjustment component is installed. The adjustment component includes a side plate, a side adjustment seat, two side optical axes, a side adjustment screw, a rear adjustment seat, a rear adjustment screw, two rear optical axes, and a light source lens sleeve.

[0007] The side plate is fixedly connected to one side of the upper surface of the base. The two ends of the two side optical axes are fixedly connected to the side plate and the base respectively. The bottom end of the side adjustment screw is rotatably connected to the upper surface of the base. The side adjustment seat is slidably connected to the outer wall of the side optical axis through a linear bearing. A fixed frame is fixedly connected to the rear of the side adjustment seat. The two ends of the two rear optical axes are symmetrically fixedly connected to the inner top wall and inner bottom wall of the fixed frame. The bottom end of the rear adjustment screw is rotatably connected to the inner bottom wall of the fixed frame. The rear adjustment seat is slidably connected to the outer wall of the rear optical axis through a linear bearing. A first rotating shaft is fixedly connected to the front of the outer wall of the light source lens sleeve.

[0008] More preferably, the side adjustment seat is threaded to the outer wall of the side adjustment screw, and the top end of the side adjustment screw passes through the top of the side plate and is rotatably connected to the side plate.

[0009] More preferably, the rear adjustment seat is threaded to the outer wall of the rear adjustment screw, and the top end of the rear adjustment screw passes through the top of the fixed frame and is rotatably connected to the fixed frame.

[0010] More preferably, the first rotating shaft is rotatably connected to the inside of the side plate via a bearing.

[0011] More preferably, the rear part of the outer side wall of the light source lens sleeve is fixedly connected to two second rotating shafts, which are movably connected to the interior of the rear adjustment seat.

[0013] More preferably, a linear laser light source lens is disposed inside the lens sleeve of the light source.

[0014] More preferably, the linear laser light source lens is installed inside the light source lens sleeve by a locking screw.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] This invention adjusts the pitch angle of the linear laser light source lens by rotating a rear adjusting screw, which drives a rear adjusting seat via a thread. The rear adjusting seat, through a second rotating shaft, drives the light source lens sleeve, which in turn rotates through a first rotating shaft. By rotating a side adjusting screw, the side adjusting seat moves upward or downward along the side optical axis, driving the light source lens sleeve and thus adjusting the height of the exit axis of the linear laser light source lens. Compared to existing technologies, this invention allows the light source lens sleeve to move parallel downward or upward when adjusting the height of the exit axis of the linear laser light source lens, thereby maintaining a constant pitch angle. This effectively reduces operational complexity, improves adjustment efficiency, and avoids additional errors during multiple adjustments.

Detailed Implementation

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1-5 As shown, this utility model embodiment provides a light source lens adjustment bracket, including a base 31, on which an adjustment component 101 is installed. The adjustment component 101 includes a side plate 11, a side adjustment seat 12, two side optical axes 13, a side adjustment screw 14, a rear adjustment seat 15, a rear adjustment screw 16, two rear optical axes 17, and a light source lens sleeve 18.

[0028] Side plate 11 is fixedly connected to one side of the upper surface of base 31. The two ends of the two side optical axes 13 are fixedly connected to side plate 11 and base 31 respectively. The bottom end of side adjusting screw 14 is rotatably connected to the upper surface of base 31. Side adjusting seat 12 is slidably connected to the outer wall of side optical axis 13 through linear bearing. Through the cooperation of optical axis and linear bearing, the friction of side adjusting seat 12 during the lifting and lowering process can be reduced. Side adjusting seat 12 is threadedly connected to the outer wall of side adjusting screw 14. The top end of side adjusting screw 14 passes through the top of side plate 11 and is rotatably connected to side plate 11. When side adjusting screw 14 is rotated, side adjusting screw 14 drives side adjusting seat 12 through thread. Side adjusting seat 12 moves up or down along side optical axis 13. When side adjusting seat 12 moves, it drives light source lens sleeve 18. Thus, the height of the emission axis of the linear laser light source lens 20 can be adjusted.

[0029] During the adjustment process, the light source lens sleeve 18 moves parallel downward or upward without changing the pitch angle of the linear laser light source lens 20, thereby reducing the complexity of operation, improving adjustment efficiency, and preventing the introduction of additional errors during multiple adjustments.

[0030] A fixed frame 121 is fixedly connected to the rear of the side adjustment seat 12. The two ends of the two rear optical shafts 17 are symmetrically fixedly connected to the inner top wall and inner bottom wall of the fixed frame 121. The bottom end of the rear adjustment screw 16 is rotatably connected to the inner bottom wall of the fixed frame 121. Thus, the position of the rear optical shaft 17 and the rear adjustment screw 16 can be limited by the fixed frame 121.

[0031] The rear adjustment seat 15 is slidably connected to the outer wall of the rear optical axis 17 via a linear bearing. The rear adjustment seat 15 is threadedly connected to the outer wall of the rear adjustment screw 16. The top end of the rear adjustment screw 16 passes through the top of the fixed frame 121 and is rotatably connected to the fixed frame 121. When the rear adjustment screw 16 is rotated, the rear adjustment screw 16 drives the rear adjustment seat 15 through the thread. The rear adjustment seat 15 moves up or down along the rear optical axis 17. At this time, the pitch angle of the linear laser light source lens 20 can be adjusted.

[0032] Two second rotating shafts 22 are fixedly connected to the rear part of the outer side wall of the light source lens sleeve 18. The second rotating shafts 22 are movably connected to the interior of the rear adjustment seat 15. The interior of the rear adjustment seat 15 is provided with a strip groove that allows the second rotating shafts 22 to slide, so that when the rear adjustment seat 15 moves up or down, it can make way for the second rotating shafts 22.

[0033] A first rotating shaft 19 is fixedly connected to the front of the outer side wall of the light source lens sleeve 18. The first rotating shaft 19 is rotatably connected to the inside of the side plate 11 through a bearing. When the rear adjustment seat 15 moves up or down, the rear adjustment seat 15 drives the light source lens sleeve 18 through the second rotating shaft 22. The light source lens sleeve 18 rotates through the first rotating shaft 19, thereby adjusting the pitch angle of the linear laser light source lens 20.

[0034] In one embodiment, the top of the light source lens sleeve 18 is threaded with two locking screws 21. A linear laser light source lens 20 is provided inside the light source lens sleeve 18. The linear laser light source lens 20 is installed inside the light source lens sleeve 18 by the locking screws 21. The shape of the light source lens sleeve 18 is adapted to the shape of the linear laser light source lens 20. The locking screws 21 facilitate the installation and fixation of the linear laser light source lens 20.

[0035] When this utility model is in operation: the linear laser light source lens 20 is installed inside the light source lens sleeve 18 and fixed with locking screws 21;

[0036] When it is necessary to adjust the pitch angle of the linear laser light source lens 20, the rear adjustment screw 16 is rotated. The rear adjustment screw 16 drives the rear adjustment seat 15 through the thread. The rear adjustment seat 15 moves up or down along the rear optical axis 17. The rear adjustment seat 15 drives the light source lens sleeve 18 through the second rotating shaft 22. The light source lens sleeve 18 rotates through the first rotating shaft 19, thereby adjusting the pitch angle of the linear laser light source lens 20.

[0037] When it is necessary to adjust the height of the emission axis of the linear laser light source lens 20, rotate the side adjustment screw 14. The side adjustment screw 14 drives the side adjustment seat 12 through the thread. The side adjustment seat 12 moves up or down along the side optical axis 13. When the side adjustment seat 12 moves, it drives the light source lens sleeve 18. The light source lens sleeve 18 drives the linear laser light source lens 20. Thus, the height of the emission axis of the linear laser light source lens 20 can be adjusted at this time.

[0038] Compared with the prior art, when adjusting the height of the emission axis of the linear laser light source lens 20, the lens sleeve 18 can move parallel downward or upward, thereby keeping the pitch angle of the linear laser light source lens 20 unchanged, effectively reducing the complexity of operation, improving the adjustment efficiency, and avoiding the generation of additional errors in multiple adjustment processes.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
