Description

A deformation-resistant, ultra-long industrial line light source fixing mechanism Technical Field

[0001] This utility model belongs to the field of linear light source fixing, specifically relating to a deformation-resistant ultra-long industrial linear light source fixing mechanism. Background Technology

[0002] A line light source generally refers to a light source that emits an extremely narrow, straight strip of light. It can illuminate the surface of the object being measured from the side or at a specific angle, forming a linear light band. This effectively enhances the details of the object's surface, such as textures and scratches, so that surface defects can be captured and detected by a camera. Industrial line light sources are commonly used for printing quality inspection, steel plate surface inspection, and surface defect detection of thin film products such as plastic films.

[0003] Typical industrial line light sources are generally less than 1 meter in length along the axis. The housing is made of aluminum alloy and is usually fixed at both ends, leaving the middle section suspended. However, in certain applications, such as irradiating and inspecting wide plastic films, ultra-long industrial line light sources with an axial length of 2 meters or more are required. For these ultra-long line light sources, if the conventional two-end fixing method is used, the originally straight housing will gradually bend and deform due to the prolonged suspension and gravity in the middle section. Once significant deformation occurs, the light source performance deteriorates, affecting the surface defect detection effect. Summary of the Invention

[0004] This utility model provides a deformation-resistant, ultra-long industrial line light source fixing mechanism, aiming to overcome the above-mentioned shortcomings in the existing technology.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A deformation-resistant ultra-long industrial linear light source fixing mechanism, which includes a light rod, a support base and a fixing clamp. Multiple fixing clamps are provided and are evenly spaced along the axial direction on the top surface of the light source housing. The number of fixing clamps is at least three and the axial distance between two adjacent fixing clamps on the light source housing is 30-60cm. The light rod passes through the fixing clamps in sequence and is clamped and fixed by the fixing clamps. The two ends of the light rod are respectively rotatably connected to the support base, and the support base is provided with locking and positioning bolts. When the locking and positioning bolts are tightened, the light rod and the support base are locked together. The front side of the light source housing is provided with a light emission port, and the rear side is provided with multiple cooling fans evenly spaced.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the fixing clamp includes an upper clamp body, a lower clamp body, a fixing bolt, and a clamping bolt. The lower clamp body is fixedly connected to the top wall of the light source housing by the fixing bolt. The upper clamp body is fixedly connected to the lower clamp body by clamping bolts provided on the front and rear sides. The upper clamp body is provided with a downward-opening semi-circular groove, and the lower clamp body is provided with an upward-opening semi-circular groove. When the upper clamp body and the lower clamp body are fixedly connected by the clamping bolt, a circular through hole is formed in the middle for the light rod to pass through and be clamped and fixed.

[0008] Furthermore, the lower clamp has a countersunk screw hole at the bottom of the semi-circular groove, and the fixing bolt passes through the countersunk screw hole and is fixedly connected to the light source housing.

[0009] Furthermore, the upper clamping body is an arched block, and the lower clamping body is a cuboid block with a semi-circular groove on its top surface.

[0010] Furthermore, the optical rod is a tempered round optical rod with a length of more than 2 meters and a diameter of more than 1.5 cm.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention features multiple evenly spaced fixing clips on the top surface of the housing of an ultra-long industrial line light source. These clips are clamped to a long, straight optical rod. The optical rod is rigid and resistant to deformation, thus the housing connected to it via the multiple fixing clips is also protected from deformation by the limiting and straightening effect of the optical rod. This ensures that the long housing maintains its straightness for a long time during actual use, providing a more durable, high-quality line light source and guaranteeing the detection effect on the illuminated object. The two ends of the optical rod are rotatably connected to the support base, facilitating the adjustment of the illumination angle. After adjustment, the positioning bolts are tightened for easy installation and adjustment. The optical rod and fixing clips are all located on the top surface of the housing, without affecting the installation and heat dissipation effect of the side cooling fan.

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] In the description of this utility model, if terms such as "upper", "lower", "left", "right", "top", "bottom", "inner", and "outer" are used to indicate the orientation or positional relationship, the orientation or positional relationship indicated is based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] As shown in Figures 1 to 4, this utility model provides a deformation-resistant ultra-long industrial line light source fixing mechanism, which includes a light rod 1, a support base 2, and fixing clamps 3. Multiple fixing clamps 3 are provided and are evenly spaced along the axial direction on the top surface of the light source housing 4. The number of fixing clamps 3 is at least three, and the distance between two adjacent fixing clamps 3 along the axial direction of the light source housing 4 is 30-60cm. The light rod 1 passes through the fixing clamps 3 in sequence and is clamped and fixed by the fixing clamps 3. The two ends of the light rod 1 are respectively rotatably connected to the support base 2, and the support base 2 is provided with locking positioning bolts. When the locking positioning bolts are tightened, the light rod 1 and the support base 2 are locked together. The front side of the light source housing 4 is provided with a light emission port 5, and the rear side is provided with multiple cooling fans 6 evenly spaced.

[0022] It should be noted that the fixing clips located on both sides of the light source housing along the axial direction do not necessarily need to be adjacent to the two ends of the light source housing. Instead, they can be spaced 15-30cm apart. This is because if they are adjacent to the two ends of the light source housing, they will be too close to the support base, and it will also be difficult to appropriately reduce the number of fixing clips. Anti-slip rubber pads can be set on the clamping surfaces of the fixing clips used to hold the light rod to ensure a good clamping and positioning effect without damaging the light rod. Similarly, elastic rubber pads can also be set between the end face of the locking positioning bolt used to press the light rod and the outer wall of the light rod to ensure a good clamping and positioning effect without damaging the light rod.

[0023] In one embodiment of this utility model, the fixing clamp 3 includes an upper clamp body 7, a lower clamp body 8, a fixing bolt 9, and a clamping bolt 10. The lower clamp body 8 is fixedly connected to the top wall of the light source housing 4 by the fixing bolt 9. The upper clamp body 7 is fixedly connected to the lower clamp body 8 by the clamping bolts 10 provided on the front and rear sides. The upper clamp body 7 is provided with a semi-circular groove with an opening facing downwards, and the lower clamp body 8 is provided with a semi-circular groove with an opening facing upwards. When the upper clamp body 7 and the lower clamp body 8 are fixedly connected by the clamping bolts 10, a circular through hole is formed in the middle for the light rod 1 to pass through and be clamped and fixed.

[0024] It should be noted that fixing the lower clamp to the light source housing does not necessarily require fixing bolts; welding or bonding can also be chosen depending on the situation.

[0025] In one embodiment of this utility model, the lower clamp 8 has a countersunk screw hole at the bottom of the semi-circular groove, and the fixing bolt 9 passes through the countersunk screw hole and is fixedly connected to the light source housing 4.

[0026] It should be noted that, preferably, a recessed groove is provided along the axial direction in the middle of the top surface of the light source housing, and the fixing bolt is fixedly connected to the bottom of the recessed groove. The front and rear sides of the bottom of the lower clamp are pressed against the area on both sides of the top surface of the light source housing located in the recessed groove, which has a better fixing effect and makes the top surface of the light source housing less prone to deformation.

[0027] In one embodiment of this utility model, the upper clamping body 7 is an arched block, and the lower clamping body 8 is a cuboid block with a semi-circular groove on its top surface.

[0028] It should be noted that the upper clamp is arched and the lower clamp is rectangular, which is aesthetically pleasing and provides good clamping effect for the bare rod.

[0029] In one embodiment of this utility model, the optical rod 1 is a tempered optical rod with a length of more than 2 meters and a diameter of more than 1.5 cm.

[0030] It should be noted that the strength, hardness, corrosion resistance and deformation resistance of the smooth round rod are significantly enhanced through heat treatment, thus better realizing its function.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
