[0005] When collecting data through the photosensitive panel, long-term laser irradiation will cause heat accumulation. Since the photocomposite material is affected by temperature, the material curing rate changes nonlinearly, thus affecting the sensitivity of the photosensitive panel. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art that long-term laser irradiation will produce heat accumulation, and the photocomposite material will be affected by temperature, resulting in nonlinear changes in the material curing rate, thereby affecting the sensitivity of the photosensitive panel, and a laser track scanning system is proposed.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions: A laser track scanning system, comprising: a workbench, a photosensitive plate arranged inside the workbench, a sliding frame slidably arranged on the workbench, and a scanning device arranged in the middle of the sliding frame, wherein a mounting groove is opened in the middle of the workbench, the photosensitive plate is installed in the mounting groove, and there is a sliding space between the bottom of the photosensitive plate and the bottom of the mounting groove; Inside the sliding space, a heat dissipation component is provided. The heat dissipation component includes a blower, a telescopic pipe, two heat dissipation pipes, and two connectors. An installation opening is formed in the middle of the installation groove. The blower is installed inside the installation opening, and an upward air flow is formed from bottom to top. The telescopic pipe is fixedly installed on the air outlet of the blower at the upper end. The two heat dissipation pipes are symmetrically and fixedly connected to both ends of the telescopic pipe. The two connectors are symmetrically and fixedly connected to the ends of the two heat dissipation pipes away from each other, and are connected to the sliding frame; A heat dissipation space is formed at the bottom of the photosensitive plate. The heat dissipation pipe is arranged inside the heat dissipation space. The heat dissipation pipe is wavy, and a plurality of heat dissipation strip openings are formed on the upper surface.

[0008] Preferably, the sliding frame includes two electromagnetic sliders, two telescopic side frames, and a top frame. Two sliding grooves are symmetrically formed on both sides of the workbench. The two electromagnetic sliders are symmetrically arranged and slidably arranged inside the two sliding grooves. The two telescopic side frames are respectively fixedly connected to the electromagnetic sliders. The top frame is fixedly connected to the upper ends of the two telescopic side frames. The scanning device is arranged below the top frame.

[0009] Preferably, the scanning device includes a reflective imaging component and a galvanometer component. The reflective imaging component is slidably installed on the sliding frame, and the galvanometer component is arranged on the side of the reflective imaging component.

[0010] Preferably, the photosensitive plate includes a photoresistor layer and a substrate. The substrate is fixedly connected to the bottom side of the photoresistor layer. The heat dissipation space is formed on the bottom side of the substrate.

[0011] Preferably, the connector includes a fixed block and a connecting block. The connecting block is fixedly connected to the end of the heat dissipation pipe. The fixed block is fixedly connected to the side of the connecting block away from the heat dissipation pipe, and a gas guiding space communicating with the heat dissipation pipe is formed inside.

[0012] Preferably, two cleaning components are symmetrically arranged between the two connecting blocks. The area between the two cleaning components is the scanning area. The cleaning components are used to clean the surface of the photosensitive plate.

[0013] Preferably, the cleaning component includes two rotating seats, two communicating pipes, a dust suction pipe, and an air extraction pipe. The two rotating seats are respectively rotatably installed on the two connecting blocks on both sides of the workbench. The communicating pipe is fixedly connected to the rotating seat, and the two communicating pipes are Z-shaped. The dust suction pipe is fixedly connected between the two communicating pipes, and the dust suction port is arranged below. The air extraction pipe is communicated between the connecting block and the lower end of the blower.

[0014] Preferably, cleaning strips are arranged on the sides of the two dust suction pipes away from each other. The cleaning strips are made of elastic materials and are used to clean the surface of the photosensitive plate.

[0015] Preferably, a filtering component is arranged inside the air guiding space. The filtering component is used to filter the particles introduced into the air guiding space by the cleaning component. The filtering component includes a filter plate, a magnetic strip, a scraping strip and a plurality of magnetic blocks. The filter plate is fixedly installed at the position where the air guiding space communicates with the air extraction pipe. The magnetic strip is arranged in a limited sliding manner on the side of the filter plate away from the air extraction pipe. The scraping strip is fixedly connected to the side of the magnetic strip close to the filter plate. A plurality of the magnetic blocks are fixedly connected to the installation groove, and the magnetic blocks are arranged at intervals. The sides of the magnetic blocks close to the magnetic strip have the same magnetism.

[0016] Preferably, a light shielding plate is vertically and fixedly connected to the dust suction pipe. The two symmetrically arranged light shielding plates are used for shielding the scanning area.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. After the fan is started, an upward air flow is generated. Since the position of the heat dissipation strip opening is close to the photosensitive plate, the air is quickly ejected through the heat dissipation strip opening for cooling, forming a heat dissipation area, thereby accelerating the rapid heat exchange at the bottom of the photosensitive plate and avoiding the influence of temperature on the photosensitivity of the photosensitive plate. At the same time, the heat dissipation pipeline will move along with the sliding rack, so as to correspond to the scanning device arranged on the sliding rack. While the scanning device is working, the heat dissipation of the corresponding position of the photosensitive plate is completed, ensuring the effect of accurate heat dissipation. 2. The cleaning components are arranged on both sides directly below the scanning device. Before the scanning device scans, the positions to be scanned can be cleaned. During cleaning, through the suction force generated by the lower fan, the suction ports below the dust suction pipe quickly collect and clean the particles and impurities on the photosensitive plate, ensuring that the scanning device will not be affected during the scanning process and improving the accuracy of the scanning trajectory. 3. Before the object is placed on the photosensitive plate, the cleaning strip is driven by the sliding rack to move, and the surface of the photosensitive plate is pushed and cleaned, avoiding sundries remaining on the surface of the photosensitive plate and ensuring the accuracy of the scanning trajectory of the photosensitive plate. 4. The fan drives the heat dissipation component and the cleaning component at the same time, and the surface of the photosensitive plate can be cleaned while the heat dissipation is completed, optimizing the overall structure and fulfilling various usage requirements through the same power source. 5. The magnetic strip will intermittently approach the magnetic block, and a repulsive force will be generated between the magnetic strip and the magnetic block. The repulsive force will drive the magnetic strip to move upward. During the upward movement of the magnetic strip, the cleaning strip fixed on the magnetic strip will scrape the surface of the filter plate, thereby cleaning the particles blocked on the filter plate and avoiding the blockage of the mesh holes by the particles, which affects the normal flow of air. 6. By arranging two light shielding plates on the dust suction pipe, the whole scanning area can be blocked from light, reducing the influence of external light on the laser beam, thereby improving the accuracy of laser scanning.

Detailed Description of the Invention

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present invention are only for the convenience of description and are not used to limit the scope of implementation of the present invention. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present invention.

[0022] Refer to Figures 1 - 8, a laser trajectory scanning system, comprising: a workbench 1, a photosensitive plate 2 disposed inside the workbench 1, a sliding frame 3 slidably disposed on the workbench 1, and a scanning device 4 disposed in the middle of the sliding frame 3. An installation groove is formed in the middle of the workbench 1. The photosensitive plate 2 is installed inside the installation groove, and there is a sliding space between the bottom of the photosensitive plate 2 and the bottom of the installation groove; A heat dissipation component 5 is disposed inside the sliding space. The heat dissipation component 5 includes a fan 51, a telescopic tube 52, two heat dissipation pipes 53, and two connectors 54. An installation opening is formed in the middle of the installation groove. The fan 51 is installed inside the installation opening, and an upward air flow is formed from bottom to top. The telescopic tube 52 is fixedly installed on the air outlet of the upper end of the fan 51. The two heat dissipation pipes 53 are symmetrically and fixedly connected to both ends of the telescopic tube 52. The two connectors 54 are symmetrically and fixedly connected to the ends of the two heat dissipation pipes 53 away from each other, and are connected to the sliding frame 3; A heat dissipation space is formed at the bottom of the photosensitive plate 2. The heat dissipation pipe 53 is disposed inside the heat dissipation space. The heat dissipation pipe 53 is wavy, and a plurality of heat dissipation strip openings are formed on the upper surface.

[0023] In the embodiments applying the above technical solutions, during the laser scanning process, line laser scanning is formed by the scanning device 4. Long-time laser scanning will affect the change of the material on the photosensitive plate 2, thereby affecting the scanning accuracy. It is necessary to control the temperature of the photosensitive plate 2. By disposing the heat dissipation component 5 inside the space below the photosensitive plate 2, the heat accumulated on the photosensitive plate 2 can be absorbed to maintain the temperature of the photosensitive plate 2; After the fan 51 is started, an upward air flow is generated. Since the heat dissipation strip openings are close to the photosensitive plate 2, air is quickly ejected through the heat dissipation strip openings for cooling to form a heat dissipation area, thereby accelerating the rapid heat exchange at the bottom of the photosensitive plate 2 and avoiding the influence of temperature on the photosensitive sensitivity of the photosensitive plate 2; At the same time, the heat dissipation pipe 53 will move along with the sliding frame 3, so as to correspond to the scanning device 4 disposed on the sliding frame 3. While the scanning device 4 is working, heat dissipation at the corresponding position of the photosensitive plate 2 is completed, ensuring the effect of accurate heat dissipation. The telescopic tube 52 will be stretched along with the movement of the heat dissipation pipe 53 to ensure the connection between the heat dissipation pipe 53 and the fan 51.

[0024] The present invention can control the temperature of the photosensitive plate 2 at the scanning position, thereby ensuring the sensitivity of the photosensitive plate 2.

[0025] The preferred technical solution in this embodiment: Refer to Figure 2, the sliding frame 3 includes two electromagnetic sliders 31, two telescopic side frames 32 and a top frame 33. Two sliding grooves are symmetrically formed on both sides of the workbench 1. The two electromagnetic sliders 31 are symmetrically and slidably arranged inside the two sliding grooves. The two telescopic side frames 32 are respectively fixedly connected to the electromagnetic sliders 31. The top frame 33 is fixedly connected to the upper ends of the two telescopic side frames 32. The scanning device 4 is arranged below the top frame 33.

[0026] When adjusting the position by means of a gear or a runner, certain vibrations will be generated, which will affect the smooth movement of the scanning device 4 on the top frame 33. By arranging the electromagnetic sliders 31 on both sides, the falling of external impurities into the sliding grooves is reduced, ensuring the stable sliding of the electromagnetic sliders 31, thereby reducing the deviation generated during the movement of the sliding frame 3 and ensuring the accuracy of the trajectory scanning.

[0027] Refer to Figure 2 , the scanning device 4 includes a reflective imaging component 41 and a galvanometer component 42. The reflective imaging component 41 is slidably mounted on the sliding frame 3. The galvanometer component 42 is arranged on the side of the reflective imaging component 41; The photosensitive plate 2 includes a photoresistor layer 21 and a substrate 22. The substrate 22 is fixedly connected to the bottom side of the photoresistor layer 21. The heat dissipation space is formed on the bottom side of the substrate 22.

[0028] During the process of trajectory scanning, a laser emitter inside the reflective imaging component 41 emits a laser beam. Through multiple emitting mirrors inside the galvanometer component 42, a two-dimensional line laser is formed, thereby improving the scanning effect.

[0029] The generated laser beam will perform laser scanning on the surface of the photosensitive plate 2, thereby drawing an invisible trajectory record diagram. The generated record diagram will be recognized and saved by the processor, so as to completely and detailedly record and use the scanned trajectory, ensuring the accuracy of processing or analysis using the trajectory.

[0030] Refer to Figure 5 and Figure 8 , the connecting member 54 includes a fixing block 541 and a connecting block 542. The connecting block 542 is fixedly connected to the end of the heat dissipation pipe 53. The fixing block 541 is fixedly connected to the side of the connecting block 542 away from the heat dissipation pipe 53, and a gas guiding space communicating with the heat dissipation pipe 53 is formed inside; Two cleaning components 6 are symmetrically arranged between the two connecting blocks 542. The area between the two cleaning components 6 is the scanning area. The cleaning component 6 is used to clean the surface of the photosensitive plate 2; The cleaning component 6 includes two rotating seats 61, two connecting pipes 62, a dust suction pipe 63 and an air extraction pipe 64. The two rotating seats 61 are respectively rotatably installed on two connecting blocks 542 on both sides of the workbench 1. The connecting pipe 62 is fixedly connected to the rotating seat 61, and the two connecting pipes 62 are Z-shaped. The dust suction pipe 63 is fixedly connected between the two connecting pipes 62, and the dust suction port is arranged below. The air extraction pipe 64 is communicated between the connecting block 542 and the lower end of the fan 51; On one side of the two dust suction pipes 63 away from each other, a cleaning strip 7 is arranged. The cleaning strip 7 is made of an elastic material and is used for cleaning the surface of the photosensitive plate 2.

[0031] After the laser beam is projected onto the photosensitive plate 2, if there are particles or sundries on the upper side of the photosensitive plate 2, it will affect the information collection of the photosensitive plate 2 for the beam, resulting in deviation of the trajectory and affecting the subsequent use of the trajectory. Therefore, before scanning the laser trajectory, it is necessary to clean the particles and impurities on the photosensitive plate 2 to ensure the accurate collection of the laser trajectory by the photosensitive plate 2.

[0032] Since the cleaning component 6 is arranged on both sides directly below the scanning device 4, it can clean the position to be scanned before the scanning device 4 scans. During cleaning, through the suction force generated by the lower fan 51, the suction end of the fan 51 is connected to the air extraction pipe 64, and the dust suction port below the dust suction pipe 63 quickly collects and cleans the particles and impurities on the photosensitive plate 2, ensuring that the scanning device 4 will not be affected during the scanning process and improving the accuracy of the scanning trajectory.

[0033] Since the thicknesses of different scanning objects are different, during the scanning process, in order to avoid contact with the object and cause the position of the object to shift, by setting the rotating seat 61 to drive the connecting pipes 62 on both sides to rotate, the position of the dust suction pipe 63 is changed, so as to adjust according to the thickness of the object and avoid contact with the object.

[0034] Before placing the object, since there may be sundries on the surface of the photosensitive plate 2, when placing the object, this part of the sundries will be pressed under the photosensitive plate 2, and the cleaning component 6 cannot clean this part of the sundries, thus affecting the scanning accuracy. Therefore, before the object is placed on the photosensitive plate 2, the sliding frame 3 drives the cleaning strip 7 to move to push and clean the surface of the photosensitive plate 2, avoiding sundries remaining on the surface of the photosensitive plate 2 and ensuring the accuracy of the scanning trajectory of the photosensitive plate 2.

[0035] By driving the heat dissipation component 5 and the cleaning component 6 simultaneously with the fan 51, the surface of the photosensitive plate 2 can be cleaned while completing heat dissipation, optimizing the overall structure and fulfilling multiple usage requirements with the same power source.

[0036] Refer to Figure 7, a filter assembly 8 is arranged inside the air guide space. The filter assembly 8 is used to filter the particles imported into the air guide space by the cleaning assembly 6. The filter assembly 8 includes a filter plate 81, a magnetic strip 82, a scraping strip 83 and a plurality of magnetic blocks 84. The filter plate 81 is fixedly installed at the position where the air guide space communicates with the heat dissipation pipeline 53. The magnetic strip 82 is arranged in a limited sliding manner on the side of the filter plate 81 away from the heat dissipation pipeline 53. The scraping strip 83 is fixedly connected to the side of the magnetic strip 82 close to the filter plate 81. A plurality of the magnetic blocks 84 are fixedly connected to the installation groove, and the magnetic blocks 84 are arranged at intervals. The sides of the magnetic blocks 84 close to the magnetic strip 82 have the same magnetism.

[0037] During the process of long-term particle adsorption and cleaning, a large number of particles will enter the air guide space. If these particles are not filtered, they will enter the heat dissipation pipeline 53. Due to the blockage of particle accumulation, the heat dissipation effect of the heat dissipation pipeline 53 will be affected. Therefore, it is necessary to filter the air entering the air extraction pipe 64 from the dust suction pipe 63 to reduce the accumulation of particles inside the heat dissipation pipeline 53.

[0038] By arranging the filter plate 81 inside the air guide space, the particles are filtered. However, after long-term filtration, the particles will accumulate on the filter plate 81, affecting the normal flow of air. While reducing the heat dissipation effect of the heat dissipation pipeline 53, the suction force of the dust suction pipe 63 is also reduced. It is necessary to regularly clean the blocked particles on the filter plate 81.

[0039] During the process of the connecting piece 54 sliding along with the sliding frame 3, the magnetic strip 82 will intermittently approach the magnetic block 84, and a repulsive force will be generated between the magnetic strip 82 and the magnetic block 84. The repulsive force will drive the magnetic strip 82 to move upward. During the upward movement of the magnetic strip 82, the cleaning strip 7 fixed on the magnetic strip 82 will scrape the surface of the filter plate 81, thereby cleaning the particles blocked on the filter plate 81 and preventing the particles from blocking the mesh holes and affecting the normal flow of air.

[0040] By arranging the magnetic strip 82 and the magnetic block 84, the cleaning speed can be adjusted along with the scanning speed, while reducing the energy consumption. At the same time, the magnetic strip 82 is set as an inclined downward strip. After the particles accumulate on the magnetic strip 82, they will transfer along the magnetic strip 82. During the up and down movement of the magnetic strip 82, the particles are accumulated and compacted to prevent a large amount of particles from flying up.

[0041] Refer to Figure 8 , a light shielding plate 9 is vertically and fixedly connected to the dust suction pipe 63. The two symmetrically arranged light shielding plates 9 are used for light shielding in the scanning area.

[0042] Since the scanning of the laser trajectory completely relies on the irradiation of the laser beam, when the laser trajectory is affected by the penetration of external light, it is easy to cause the dispersion of the laser beam, thereby affecting the accuracy of laser planning scanning. By setting two light-shielding plates 9 on the dust suction pipe 63, which can block the light in the entire scanning area, the influence of external light on the laser beam can be reduced, thereby improving the accuracy of laser scanning.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
