Description

Technical Field

[0001] This utility model relates to the field of light source structure technology, and in particular to a light guide rod fixing device and a light source device. Background Technology

[0002] In the field of machine vision lighting, suitable light sources help highlight product features such as scratches and cracks. Light sources include point light sources, line light sources, and planar light sources. In some applications, light guides are used to converge the light. Generally, a first V-shaped clamp and a second V-shaped clamp are used to clamp the light guide, and the first and second V-shaped clamps are fixedly connected. However, if the outer diameter of the light guide is too large, or if the installation error of the first and second V-shaped clamps is large, then when two or more light guides are connected in parallel at a fixed interval, due to the accumulation of errors, one of the light guides is very likely to be damaged due to excessive clamping force.

[0003] In view of this, it is necessary to design a light guide rod fixing device and a light source device to reduce the possibility of two light guide rods arranged side by side being damaged due to excessive clamping force.

[0004] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A light guide rod fixing device includes a first V-shaped clamp and a second V-shaped clamp arranged opposite to each other, and an adjustment device installed between the first V-shaped clamp and the second V-shaped clamp, wherein the V-shaped grooves of the first V-shaped clamp and the second V-shaped clamp are opposite to each other.

[0008] The adjustment device includes an upper clamping block and a lower clamping block arranged at intervals.

[0020] Optionally, the light guide rod fixing device further includes a fixing shell, and the first V-shaped clamp and the second V-shaped clamp are respectively fixedly connected to the fixing shell.

[0021] Optionally, both the first light guide rod and the second light guide rod are glass light guide rods.

[0022] A light source device includes a light guide rod fixing device as described in any of the preceding claims.

[0040] Example 1

[0041] In view of the defects of the existing light guide rod fixing devices, the applicant, based on years of rich practical experience and professional knowledge in the design and manufacture of such products, and in conjunction with the application of theoretical principles, actively conducted research and innovation in order to create a technology that can solve the defects of the existing technology and make the light guide rod fixing device more practical. After continuous research, design, and repeated prototype production and improvement, this utility model with real practical value has finally been created.

[0042] Please refer to Figure 1This utility model provides a light guide rod fixing device, including a first V-shaped clamp 1 and a second V-shaped clamp 2 arranged opposite to each other, and an adjustment device 3 installed between the first V-shaped clamp 1 and the second V-shaped clamp 2. The V-shaped grooves of the first V-shaped clamp 1 and the second V-shaped clamp 2 are opposite to each other, which facilitates the two light guide rods to be arranged side by side.

[0043] The adjusting device 3 includes an upper clamping block 31 and a lower clamping block 32 spaced apart. The first clamping surface 311 of the upper clamping block 31 and the second clamping surface 321 of the lower clamping block 32 form a first clamping V-groove facing the first V-shaped clamping block 1. The third clamping surface 312 of the upper clamping block 31 and the fourth clamping surface 322 of the lower clamping block 32 form a second clamping V-groove facing the second V-shaped clamping block 2. The distance between the upper clamping block 31 and the lower clamping block 32 is adjustable. In this embodiment, the distance between the upper clamping block 31 and the lower clamping block 32 is adjustable, thereby adapting to the clamping needs of light guide rods of different diameters.

[0044] In this embodiment, the light guide rod fixing device includes a first V-shaped clamping block 1, an adjusting device 3, and a second V-shaped clamping block 2 arranged sequentially from left to right. The V-shaped groove on the first V-shaped clamping block 1 and the first clamping V-groove on the adjusting device 3 can clamp one light guide rod, and the V-shaped groove on the second V-shaped clamping block 2 and the second clamping V-groove on the adjusting device 3 can clamp the other light guide rod. Since the distance between the upper clamping block 31 and the lower clamping block 32 is adjustable, and the two light guide rods simultaneously apply a reaction force to the adjusting device, the adjusting device is always positioned in the middle of the two light guide rods, avoiding excessive force on one of the light guide rods and effectively reducing the possibility of the light guide rods being damaged due to excessive clamping force. Damage refers to being crushed or injured by clamping.

[0045] It should be noted that when one of the light guide rods is subjected to a large clamping force, that light guide rod will transmit pressure to the adjusting device 3, thereby balancing the clamping pressure between the two light guide rods. In this embodiment, the adjusting device 3, by changing the distance between the upper clamping block 31 and the lower clamping block 32, and by being able to move left and right, balances the force between the two light guide rods, reducing the possibility of the two light guide rods, which are arranged side by side with spacing, being damaged due to excessive clamping force.

[0046] Optionally, the light guide rod fixing device further includes a first light guide rod 41 and a second light guide rod 42; the first light guide rod 41 is clamped by the V-groove of the first V-shaped clamping block 1 and the first clamping V-groove, and the second light guide rod 42 is clamped by the V-groove of the second V-shaped clamping block 2 and the second clamping V-groove. In this embodiment, the first light guide rod 41 and the second light guide rod 42 both have a perfectly circular cross-section perpendicular to the center line, which allows the adjusting device 3 to better balance the clamping pressure.

[0047] Optionally, the first V-shaped clamping block 1 and the second V-shaped clamping block 2 are both metal blocks, and the upper clamping block 31 and the lower clamping block 32 are both plastic blocks.

[0048] Specifically, the plastic block is relatively soft and has a certain degree of elastic deformation, which can further reduce the possibility of the light guide rod being damaged due to excessive clamping force.

[0049] Optionally, such as Figure 2 The adjusting device 3 also includes an adjusting bolt 5; the upper clamping block 31 is provided with a first connecting through hole, and the lower clamping block 32 is provided with a second connecting through hole corresponding to the first connecting through hole. The screw of the adjusting bolt 5 passes through the first connecting through hole and the second connecting through hole in sequence, and a nut is installed on the screw passing through the second connecting through hole. In this embodiment, by rotating the adjusting bolt 5 and the nut, the distance between the upper clamping block 31 and the lower clamping block 32 is changed, thereby changing the clamping pressure on the light guide rod and making the clamping pressure more reasonable.

[0050] Optionally, such as Figure 3 An elastic element 6 is installed between the upper clamping block 31 and the lower clamping block 32. One end of the elastic element 6 is connected to the upper clamping block 31, and the other end is connected to the lower clamping block 32. When the two light guide rods exert greater pressure on the adjusting device 3, the elastic element 6 is stretched, thereby increasing the clamping space between the adjusting device 3 and the first V-shaped clamping block 1, and also increasing the clamping space between the adjusting device 3 and the second V-shaped clamping block 2, thus avoiding excessive pressure on the light guide rods. In addition, the elastic element 6 can prevent the light guide rods from vibrating during actual operation.

[0051] Optionally, the V-groove of the first V-shaped clamping block 1 includes a first groove wall 11 and a second groove wall 12; the first clamping surface 311 is parallel to the first groove wall 11, and the second clamping surface 321 is parallel to the second groove wall 12, so that the light guide rod can be located in the middle of the V-groove of the first V-shaped clamping block 1 and the first clamping V-groove.

[0052] Optionally, the V-groove of the second V-shaped clamping block 2 includes a third groove wall 21 and a fourth groove wall 22; the third clamping surface 312 is parallel to the third groove wall 21, and the fourth clamping surface 322 is parallel to the fourth groove wall 22.

[0053] Optionally, the light guide rod fixing device further includes a fixing shell, with the first V-shaped clamp 1 and the second V-shaped clamp 2 respectively fixedly connected to the fixing shell. Preferably, the adjusting device 3 is slidably installed between the first V-shaped clamp 1 and the second V-shaped clamp 2, and the sliding direction is perpendicular to the line connecting the center of the first V-shaped clamp 1 and the center of the second V-shaped clamp 2. Both the upper clamping block 31 and the lower clamping block 32 in the adjusting device 3 can slide independently.

[0054] Optionally, both the first light guide 41 and the second light guide 42 are glass light guides.
