DETAILED DESCRIPTION

[0029] The specific implementation of the utility model will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

[0030] As Figures 1 to 4 shown, the light source adjusting mechanism of the laser irradiation instrument of the utility model comprises:

[0031] Drive assembly 1 for providing power;

[0032] Adjusting assembly 2 is connected with drive assembly 1, and the adjustment of light source 4 is realized through the power of drive assembly 1;

[0033] Control assembly 3 is electrically connected with drive assembly 1, and is used for controlling the operation of drive assembly 1;

[0034] In the working process, the driving assembly 1 serves as the power source of the entire adjusting mechanism and can generate power, which can be in the form of rotary power, linear motion power, etc. When the driving assembly 1 generates power, the power is transmitted to the adjusting assembly 2, which adjusts the light source 4 according to the received power. The control assembly 3 sends instructions to the driving assembly 1 to control the operating state of the driving assembly 1, such as starting, stopping, changing the power size and direction, etc., so as to realize accurate control of the light source 4. Because the operation of the driving assembly 1 can be flexibly adjusted according to actual needs, the parameters of the light source 4 can be accurately adjusted to meet the requirements of precise material processing, high-end scientific research experiments, and other scenes with high requirements for light source parameters.

[0035] The driving assembly 1 includes a motor 11, a lead screw 121, and a nut 122. The output shaft of the motor 11 is connected to the lead screw 121, and the nut 122 is fixedly connected to the adjusting assembly 2. The lead screw 121 is screwed with the nut 122. The motor 11 serves as a power source. After being powered on, the electromagnetic action inside the motor makes the motor output shaft rotate, thereby generating rotary power. The rotation of the motor output shaft directly drives the lead screw 121 to rotate synchronously. The lead screw 121 and the nut 122 form a screw transmission pair. When the lead screw 121 rotates, the nut 122 moves linearly along the axis of the lead screw 121 due to the action of the screw thread, thereby converting the rotary power of the motor 11 into the linear motion power of the nut 122. The linear motion of the nut 122 drives the adjusting assembly 2 to move. The adjusting assembly 2 is associated with the light source 4, and its movement changes the position, angle, spot size, etc. of the light source 4, thereby realizing the adjustment of the light source. The transmission of the lead screw 121 and the nut 122 has high precision. The pitch of the lead screw 121 can be accurately machined, and the precise control of the motor is realized to achieve high-precision adjustment of the light source. Compared with some other transmission methods, the return error of the transmission of the lead screw 121 and the nut 122 is small, and accurate positioning can be achieved when adjusting in the forward and reverse directions, thereby ensuring the repeatability and stability of the adjustment.

[0036] Preferably, the adjusting assembly 2 includes at least one adjusting component 21 for adjusting at least one of the position, spot size, or illumination angle of the light source 4. The adjusting assembly 2 realizes the adjustment of the light source 4 through a specific mechanical structure and movement mode. The number of adjusting components 21 can be increased or decreased to realize the adjustment of one parameter or even the simultaneous adjustment of multiple parameters, thereby adapting to various application requirements and technical developments.

[0037] Specifically, the adjusting component 21 for adjusting the position of the light source 4 comprises a sliding block 211 and a guide rail 212, the sliding block 211 is slidingly installed on the guide rail 212, the light source 4 is arranged on the sliding block 211, and the position of the light source 4 is adjusted by sliding the sliding block 211 on the guide rail 212; the combination of the sliding block 211 and the guide rail 212 is a relatively basic and simple mechanical structure, the simple structure makes the manufacturing and installation of the adjusting component 21 relatively low in difficulty and relatively low in cost, at the same time, the simple structure reduces the number of parts, reduces the probability of failure, and improves the reliability and stability of the equipment; the nut 122 in the driving assembly 1 is fixedly connected with the sliding block 211, the screw rod 121 rotates to drive the nut 122 to move linearly, and then drives the sliding block 211 to slide on the guide rail 212; the guide rail 212 plays a role in guiding and restricting the movement track of the sliding block 211, so as to ensure that the light source 4 can be adjusted in position according to a predetermined straight line direction, reduce the shaking and deviation of the sliding block 211 in the sliding process, and stable movement characteristics can ensure that the light source 4 will not shake or jump during the position adjustment process, so as to ensure the accuracy and accuracy of the position adjustment of the light source 4; the length of the guide rail 212 can be designed and customized according to actual needs, so as to determine the sliding range of the sliding block 211, that is, the position adjustment range of the light source 4, and different lengths of the guide rail 212 can be designed according to different application scenarios to meet the diversified needs of the position adjustment range of the light source 4.

[0038] The adjusting component 21 for adjusting the size of the light spot comprises an adjustable lens group 213, the adjustable lens group 213 changes the size of the light spot by adjusting the distance or angle between the lenses 2131, and the principle is based on the lens imaging law in the optical principle; when the distance between the lenses 2131 is adjusted, the refraction of light passing through the lens group 213 will change, taking a lens group composed of two convex lenses as an example, changing the distance between the lenses will affect the convergence or divergence degree of light, when the distance between the lenses increases, the convergence point of light will change, so that the size of the light spot formed in the target position changes, on the contrary, reducing the distance between the lenses will also have a corresponding effect on the size of the light spot; when the angle of the lenses 2131 is adjusted, the incident angle of light will change, and then the refraction direction of light after passing through the lens will change, different refraction directions will lead to different distributions of light at the target position, so as to change the size of the light spot, taking the slight inclination of the lens as an example, the originally parallel incident light will exit at different angles after passing through the lens, so that the light spot becomes larger or smaller in a certain direction; the adjustable lens group 213 can be conveniently integrated into the overall structure of the laser irradiation instrument, and through cooperation with the driving assembly 1 and the control assembly 3, automatic control can be realized, the distance or angle between the lenses can be conveniently set, so as to realize automatic adjustment of the size of the light spot, improve the convenience and efficiency of operation.

[0039] The adjusting component 21 for adjusting the irradiation angle of the light source 4 comprises a mirror adjusting group 214, which changes the irradiation direction of the light source 4 by adjusting the angle of the mirror 2141; the principle is based on the law of reflection of light, that is, the reflected light and the incident light are in the same plane with the normal, and the reflected light and the incident light are located on the two sides of the normal, and the reflection angle is equal to the incidence angle; during the adjusting process, the driving assembly 1 generates power and transmits it to the mirror adjusting group 214, and converts the rotary motion of the motor 11 into the rotating action of the mirror 2141, so as to change the normal direction of the mirror 2141; when the light emitted by the light source 4 irradiates on the mirror 2141, due to the change of the normal direction of the mirror 2141, the direction of the reflected light will also change accordingly, and finally the adjusting direction of the light source 4 is realized; by accurately controlling the rotation angle of the mirror 2141, the irradiation direction of the light source 4 is accurately adjusted, and the light is accurately directed to the target position; compared with some other ways of changing the direction of light such as refraction, the use of the mirror adjusting group 214 can effectively reduce the loss of light energy, ensure that the energy of the light source 4 can be more efficiently transmitted to the target area, and improve the energy utilization efficiency of the laser irradiation instrument.

[0040] In order to further improve the adjusting precision, a position detection assembly 5 is arranged, which comprises a sensor 51 arranged on the adjusting assembly 2 or a component cooperating with the adjusting assembly 2, for detecting the position of the adjusting assembly 2 in real time; when the adjusting assembly 2 moves under the action of the driving assembly 1, the sensor 51 can sense the position change of the adjusting assembly 2 in real time; for example, the slider 211 in the adjusting assembly 2 slides on the guide rail 212, and the sensor 51 is installed on the slider 211, and the position information of the adjusting assembly 2 is obtained by sensing the position of the slider 211; the sensor 51 converts the detected position information into an electrical signal or other transmittable signal form, and transmits it to the control assembly 3; after receiving these signals, the control assembly 3 analyzes and processes them, compares the signals from the sensor 51 with the pre-set target position, judges the deviation between the actual position of the adjusting assembly 2 and the target position, and according to the judgment result of the control assembly 3 on the position deviation, the control assembly 3 will issue corresponding control instructions to the driving assembly 1, such as changing the rotating speed and direction of the motor 11, so that the adjusting assembly 2 moves towards the target position, realizes the accurate control of the position of the adjusting assembly 2, and ensures the accuracy and timeliness of the adjusting process.

[0041] The control assembly 3 comprises a controller 31 and an operation interface 32. The controller 31 is electrically connected with the driving assembly 1 and the position detection assembly 5. The operation interface 32 is used for inputting an adjustment instruction. The controller 31 controls the driving assembly 1 to operate according to the adjustment instruction and adjusts according to the information fed back by the position detection assembly 5. The operation interface 32 can be a touch screen, a button, a knob or the like, which provides a convenient interactive mode for an operator. According to different application scenarios and requirements, the adjustment instruction is input through the operation interface 32. The operation interface 32 transmits the input adjustment instruction electrical signal to the controller 31. The controller 31 analyzes and processes the received adjustment instruction, converts the instruction into a specific control signal, controls the operation of the driving assembly 1, drives the adjustment assembly 2 to move, and thus adjusts the light source 4, reduces the operation difficulty, and improves the work efficiency. Meanwhile, the controller 31 receives the position information of the adjustment assembly 2 fed back by the position detection assembly 5, compares the received actual position information with a preset target position, calculates a deviation value, and if there is a deviation, the controller 31 sends an adjustment instruction to the driving assembly 1 again according to the size and direction of the deviation, fine-tunes the operation state of the driving assembly 1, until the adjustment assembly 2 reaches the target position, and thus accurately controls the light source 4. This closed-loop control mode can effectively reduce the adjustment error, ensure that the position, spot size and irradiation angle and other parameters of the light source can accurately reach the set value, and meet the requirements of various high-precision applications, such as precision machining and high-end scientific research experiments.

[0042] External vibration and impact may cause the adjustment assembly 2 to displace or sway, thereby affecting the adjustment accuracy of the light source 4. In order to isolate external vibration and reduce the vibration interference of the adjustment assembly 2, a damping assembly 6 is arranged. The damping assembly 6 comprises a damping pad 61 and a damping spring. The damping pad 61 is arranged between the adjustment assembly 2 and the support structure 7, and the damping spring is arranged in the damping pad 61 or cooperates with the damping pad 61. When the laser irradiation instrument is subjected to external vibration or impact, the damping pad 61 first contacts and absorbs part of the energy. The damping pad 61 is made of a material with elasticity, such as rubber or silicone. When subjected to external force, these materials will elastically deform, converting mechanical energy into their own elastic potential energy, thereby slowing down the transmission of vibration and impact. The damping spring further buffers. The damping spring has good elasticity and resilience. After the damping pad 61 absorbs part of the energy, the remaining energy will be transmitted to the damping spring, causing it to compress or stretch. In this process, the damping spring also converts mechanical energy into elastic potential energy, further dissipating vibration and impact energy, and reducing the vibration impact on the adjustment assembly 2. Through the synergistic effect of the damping pad 61 and the damping spring, the influence of external vibration and impact on the adjustment assembly 2 is reduced, so that the adjustment assembly 2 can maintain a relatively stable state.
