Description

Technical Field

[0001] This utility model belongs to the field of laser technology, specifically relating to a novel 360-degree linear laser source structure. Background Technology

[0002] Existing laser line light sources with 360-degree linear light energy adjustment all use an integrated outer cylinder structure and achieve this through adjusting a translational conical mirror. A glass tube bonding hole is located at the head of the laser source's outer cylinder. After the glass tube is bonded, the symmetry of the line light source is adjusted by the gap between the glass tube and the conical mirror. Then, adhesive is applied for curing and fixing, thus bonding the conical mirror to the glass tube. After the glass tube is bonded to the outer cylinder, the 360-degree light energy achieves a state of symmetrical bright spots at both ends and symmetrical dark spots at both ends. The biggest drawback of this precision adjustment method is that it generates significant stress during the adjustment process. After product debugging and assembly, this stress gradually releases, and the light energy changes accordingly. Secondly, the glass tube is glued to the outer cylinder, which is detrimental to product repair and maintenance, thus increasing the product's processing and repair costs.

[0003] The existing laser source outer tube and lens tube are fixed with glue, and the light energy symmetry is adjusted by manually adjusting the conical lens to align the lines. This method is difficult to control the force, and the adjustment angle is fixed, which may result in failure to meet the light energy symmetry and leads to low product efficiency.

[0004] Therefore, developing a novel 360-degree linear laser source structure has great market potential. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of the prior art and provide a novel 360-degree linear laser source structure.

[0006] To solve the technical problem, the technical solution of this utility model is: a novel 360-degree linear laser source structure, including a conical lens assembly, an outer cylinder, a set screw, a lens barrel, and a rear seat.

The outer wall of the rear side of the lens barrel is provided with an arc-shaped protrusion, the inner wall of the outer cylinder is provided with a mating support arc surface, and the inner wall of the rear seat is provided with an edge. The lens barrel is installed inside the outer cylinder from the rear end, and the arc-shaped protrusion mates with the mating support arc surface. The rear seat is threadedly installed inside the rear end of the outer cylinder, and the edge abuts against the arc-shaped protrusion. The outer wall of the outer cylinder is threadedly connected with a set screw, which passes through the outer cylinder and abuts against the front outer wall of the lens barrel.

[0007] Preferably, the conical lens assembly includes a conical lens, a glass tube, and a lens mount. The conical lens is coaxially mounted inside the glass tube, the glass tube is coaxially mounted inside the front end of the lens mount, and the lens mount is threadedly mounted inside the front end of the outer cylinder.

[0008] Preferably, the outer cylinder is provided with four threaded holes in the circumference and four set screws, which pass through the four threaded holes and abut against the outer wall of the lens barrel.

[0009] Preferably, a lens is installed at one end of the lens barrel near the conical lens assembly, the lens is fixedly installed inside the front end of the lens barrel by a pressure cap, and a laser light source is installed at the rear end of the lens barrel.

[0010] Preferably, the inner wall of the outer cylinder is provided with a first threaded section, a first step, a transition hole, a mating support arc surface, a second step, and a second threaded section in sequence, and the inner diameter of the transition hole gradually decreases as it approaches the second step;

[0011] The first threaded segment is threadedly connected to the cone mirror assembly and confines the cone mirror assembly at the first step;

[0012] The front end of the lens barrel passes through the transition hole, and the front side of the arc surface protrudes and mates with the supporting arc surface;

[0013] The second threaded section is threadedly connected to the rear seat and limits the rear seat to the second step, while the edge abuts against the rear side of the arc-shaped protrusion.

[0014] Preferably, the size of the mating support arc surface is 1.5~2mm.

An arc-shaped protrusion is provided on the outer wall of the lens barrel, a matching support arc surface is provided on the inner wall of the outer barrel, and a ridge is provided on the inner wall of the rear seat. The matching support arc surface and the ridge act on the arc-shaped protrusion from the front and rear respectively to form a movable space.

At the same time, the set screw acts on the outer wall of the front end of the lens barrel, so that it moves around the formed movable space as the axis, so that the beam changes through the conical mirror surface, thereby achieving the effect of an adjustable linear light source.

[0027] Example 1

[0028] like Figures 1-3 As shown, this utility model discloses a novel 360-degree linear laser source structure, including a conical lens assembly, an outer cylinder 3, a set screw 4, a lens barrel 5, and a rear seat 6.

The outer wall of the outer cylinder 3 is threadedly connected with a set screw 4, which passes through the outer cylinder 3 and abuts against the front outer wall of the lens barrel 5.

[0029] Example 2

[0030] Preferred, such as Figure 2As shown, the conical lens assembly includes a conical lens 1, a glass tube 2, and a lens mount 10. The conical lens 1 is coaxially mounted inside the glass tube 2, the glass tube 2 is coaxially mounted inside the front end of the lens mount 10, and the lens mount 10 is threadedly mounted inside the front end of the outer cylinder 3.

[0031] The mirror base 10 is externally threaded to the outer cylinder 3, so the mirror base 10 can be disassembled, repaired or replaced. The glass tube 2 and the conical mirror 1 are bonded to the mirror base 10.

[0032] Preferred, such as Figure 1 , 2 As shown, the outer cylinder 3 is provided with four threaded holes 13 in the circumference, and there are four set screws 4. The four set screws 4 pass through the four threaded holes 13 respectively and abut against the outer wall of the lens barrel 5.

[0033] The spot in the lens barrel 5 is adjusted in 360 degrees by the force of the top screw 4, thus avoiding the instability of the linear light energy change caused by the failure of the glue to cure in time after the glue is used for bonding during the product processing.

[0034] Example 3

[0035] Preferred, such as Figure 2 As shown, a lens 12 is installed at one end of the lens barrel 5 near the conical lens assembly. The lens 12 is fixedly installed inside the front end of the lens barrel 5 by a pressure cap 11. A laser light source is installed at the rear end of the lens barrel 5.

[0036] The pressure cap 11 is interference-fitted with the front end of the lens barrel 5 and is used to fix the lens 12 to the front end of the lens barrel 5.

[0037] Example 4

[0038] Preferred, such as Figure 2 As shown, the inner wall of the outer cylinder 3 is sequentially provided with a first threaded section 14, a first step 15, a transition hole 16, a mating support arc surface 8, a second step 17, and a second threaded section 18. The inner diameter of the transition hole 16 gradually decreases as it approaches the second step 17.

[0039] The first threaded section 14 is threadedly connected to the cone lens assembly and confines the cone lens assembly at the first step 15;

[0040] The front end of the lens barrel 5 passes through the transition hole 16, and the front side of the arc protrusion 7 cooperates with the supporting arc surface 8.

[0041] The second threaded section 18 is threadedly connected to the rear seat 6 and limits the rear seat 6 to the second step 17, while the edge 9 abuts against the rear side of the arc protrusion 7.

[0042] Preferably, the size of the mating support arc surface 8 is 1.5~2mm.

[0043] The size of the supporting arc surface 8 is small, and it only needs to serve the functions of support and rotation, which reduces the difficulty of processing.

[0044] Preferably, the angle of the edge 9 is 90 degrees.

[0045] The edge 9 abuts against the arc protrusion 7, and the position between the arc protrusion 7 and the edge 9 can be finely adjusted, while the edge 9 can also maintain the finely adjusted position.

[0046] The working principle of this utility model is as follows:

[0047] like Figures 1-3 As shown, this utility model discloses a novel 360-degree linear laser light source structure, including a conical lens assembly, an outer cylinder 3, a set screw 4, a lens barrel 5, and a rear seat 6. The set screw 4 is threaded onto the outer cylinder 3. The set screw 4 is subjected to force on the lens barrel 5 within the module, causing it to be biased and the beam passing through the conical lens 1 of the conical lens assembly to change, thereby achieving an adjustable linear light source effect. This utility model uses four set screws 4 on the outer cylinder 3 to adjust the coverage area of ​​the emitted light from the lens barrel 5 on the conical lens, thereby adjusting the light energy value of symmetrical bright and dark spots. The set screws 4 are pressed against the outer wall of the lens barrel 5. After determining the light energy value, the lens barrel 5 is fixed. During product assembly, this avoids the instability of linear accuracy caused by glue failure to cure in time after bonding. At the same time, by using the cooperation of the supporting arc surface 8 and the edge 9 to cooperate with the arc surface protrusion 7, the angle can be finely adjusted, and the edge can also maintain the position after the fine-tuning angle, improving the adjustment efficiency.

[0048] This utility model discloses a novel 360-degree linear laser light source structure. An arc-shaped protrusion is provided on the outer wall of the lens barrel, a supporting arc-shaped surface is provided on the inner wall of the outer barrel, and an edge is provided on the inner wall of the rear seat. The supporting arc-shaped surface and the edge act on the arc-shaped protrusion from the front and rear respectively, forming a movable space. The edge provides limitation and support to the arc-shaped protrusion. Simultaneously, a set screw applies force to the outer wall of the front end of the lens barrel, causing it to move around the formed movable space as an axis. This causes the beam to change as it passes through the conical mirror, thereby achieving an adjustable linear light source effect.

[0049] The front side of the arc-shaped protrusion on the outer wall of the lens tube of this utility model cooperates with the supporting arc surface, and the rear side of the arc-shaped protrusion abuts against the edge. The position between the arc-shaped protrusion and the edge can be finely adjusted, and the edge can also maintain the position after fine adjustment. The fine adjustment structure is simple, the fine adjustment deflection is small, and the accuracy adjustment speed is improved.

[0050] This invention fixes the lens barrel by engaging the threaded hole of the outer cylinder with the set screw and the outer wall of the lens barrel, replacing the original bonding method. This reduces the uncertain stress release caused by adhesive bonding, thereby adjusting the symmetry of light energy and replacing the bonding method.

[0051] This utility model's conical mirror assembly is threaded inside the front end of the outer cylinder, adding a detachable and repairable mirror mount, reducing the processing and repair costs of the original structure.

[0052] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.

[0053] Many other changes and modifications can be made without departing from the concept and scope of this utility model. It should be understood that this utility model is not limited to the specific embodiments, and the scope of this utility model is defined by the appended claims.
