[0006] 3. The collimator lens positioning method is too large and easily causes the collimator lens to deform.
[0007] Therefore, a structure that is convenient for adjusting the collimating mirror is proposed to solve the above problem. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] See also Figure 1-9 In this embodiment, a structure for facilitating adjustment of the collimator lens includes a laser fixing plate 1, a collimator lens 3 extending into the cavity of the laser fixing plate 1 is installed on one side of the laser fixing plate 1, and an adjustment tool 2 is also provided on the laser fixing plate 1. The installation position of the collimator lens 3 is adjusted by the adjustment tool 2. A laser 6 is installed on the other side of the laser fixing plate 1. The straight-line distance LA between the collimator lens 3 and the laser 6 can be adjusted by the adjustment tool 2 (such as Figure 2 As shown), adjust the collimation of the light beam in sequence. When the collimating mirror 3 is adjusted to the optimal position, the adjusting tool 2 can be removed.
[0031] In order to limit the rotation and displacement of the collimator 3 in a static state and realize the positioning of the collimator 3, a groove is opened in the laser fixing plate 1, and an O-ring 4 is embedded in the groove. The outer wall of the collimator 3 contacts the inner ring of the O-ring 4, and the outer wall of the collimator 3 and the inner ring of the O-ring 4 are interference fit. The collimator 3 is made of rigid material and the O-ring 4 is made of flexible material. The interference fit between the two will produce friction, which is sufficient to limit the rotation and displacement of the collimator 3 in a static state, thereby realizing the positioning of the collimator, but the friction force is smaller than the torque applied to the collimator 3 by the adjustment tool 2.
[0032] As for how the adjustment tool 2 adjusts the collimator 3, the collimator 3 is threadedly connected to the laser fixing plate 1, and a pair of claws are fixed on the inner wall of the adjustment tool 2. A pair of grooves cooperating with the claws are provided on the side of the collimator 3 facing the adjustment tool 2. By inserting the claws of the adjustment tool 2 into the grooves of the collimator 3, the adjustment tool 2 can be used to drive the collimator 3 to rotate and adjust the installation position of the collimator 3.
[0033] like Figure 5-9 As shown, since the adjustment tool 2 is a hand-tightening structure, and the size of the adjustment tool 2 is a cylindrical shape with a diameter of 25 mm and a height of 10 mm, the axial distance LB (such as Figure 3 The tool will not interfere with other components even when there are restrictions (as shown) or when the space is small. The axis center of the adjustment tool 2 is a through-hole structure, so when the adjustment tool 2 is twisted, the operator's hand and the adjustment tool 2 will not block the laser beam, and will not affect the real-time adjustment effect. In addition, the front end of the adjustment tool 2 has an anti-error and anti-fool guide structure to prevent the claws of the adjustment tool 2 from contacting the mirror surface of the collimator 3 and causing scratches on the mirror surface. The thread pitch between the collimator 3 and the laser fixing plate 1 is 0.5mm, which can achieve fine adjustment of the collimator 3.
[0034] like Figure 4 As shown, since the collimation of the laser beam is sensitive to temperature changes, a pair of air pipe joints 5 are connected to the bottom end of the laser fixing plate 1 for installing the air inlet pipe and the air outlet pipe respectively, and air paths connected to the pair of air pipe joints 5 are also provided in the laser fixing plate 1. By injecting compressed air into the air paths of the laser fixing plate 1, the high-speed fluidity of the compressed air can be used to take away the heat generated by the laser 6 during operation, thereby achieving heat dissipation and maintaining a constant temperature.
[0035] By adopting the structure that facilitates the adjustment of the collimator lens, the position of the collimator lens can be manually fine-tuned without affecting the laser beam. The specific operation method is as follows:
[0036] Insert the claw of the adjusting tool 2 into the slot of the adjusting tool 2, and turn the adjusting tool 2. The straight-line distance LA between the collimating lens 3 and the laser can be adjusted. When the collimating lens 3 is adjusted to the optimal position, remove the adjusting tool 2, and the laser 6 emits laser, and the laser is emitted from the collimating lens 3.
