[0002] The circuit board laser cutting and printing technology is one of the important technologies in the modern electronic manufacturing field. It combines the high precision, high efficiency and flexibility of lasers and is widely used in the manufacturing and processing of printed circuit boards (PCBs). Laser cutting technology has significant advantages in PCB manufacturing. It processes materials through a high-energy laser beam, enabling high-precision cutting, drilling and engraving. It can achieve a cutting accuracy of the micron level and is suitable for the processing of complex patterns and high-density circuit boards. Laser cutting is non-contact and will not cause physical pressure on the PCB, thus avoiding damage to the PCB caused by mechanical stress; the heat-affected zone (HAZ) generated by laser cutting is extremely small and hardly causes material deformation or delamination; laser cutting is not restricted by shape and can easily meet the cutting requirements of various complex patterns.

Detailed implementation mode
[0018] 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0019] Please refer to Figure 1-7 , the present invention provides a technical solution: a laser cutting and printing device for circuit boards, including a body shell 10, an observation plate 11 is slidably connected to the front side of the body shell 10, a laser cutting mechanism 12 and a two-degree-of-freedom driving mechanism 13 are arranged inside the body shell 10, the two-degree-of-freedom driving mechanism 13 includes a mounting plate 131; a limiting shell 14, which is slidably connected to the top of the mounting plate 131, baffles 141 are slidably connected to both sides of the limiting shell 14, and four positioning rods 143 are slidably connected inside the limiting shell 14; a first ventilation tube 15 and a second ventilation tube 151, which are slidably connected to the rear side of the body shell 10, and a scraper 152 is slidably connected inside the second ventilation tube 151; a recycling module 16, which is arranged inside the body shell 10, and the recycling module 16 is used for collecting cutting waste chips.
[0020] In specific implementation, during operation, the circuit board is placed on the limit plate 142, the hydraulic rod 111 is started to drive the observation plate 11 to block the front side of the body shell 10, and the multiple hydraulic rods 149 are started to drive the limit shell 14 to move up as a whole. After the top of the limit shell 14 is higher than the limit plate 142, the laser cutting mechanism 12 is used to process the circuit board on the top of the limit plate 142. The generated waste chips will be blocked by the limit shell 14 and splashed into the limit shell 14 for preliminary collection. During the process, multiple positioning rods 143 limit the four corners of the limit plate 142 to prevent the circuit board from shifting. When the laser cutting mechanism 12 performs cutting and processing on the circuit board, the observation plate 11 blocks the body shell 10 to concentrate the smoke and dust. Starting the fan 154 inside the ventilation tube 15 can extract the smoke and dust in time and discharge it through the exhaust pipe 159. After the laser cutting mechanism 12 has completed its operation, the dual-axis motor 147 is started to drive the two one-way screws 146 to rotate, thereby driving the two push plates 145 to move closer to each other, separating the push plates 145 from the positioning rod 143, and the positioning rod 143 slides under the reset action of the spring 1441, so that the positioning rod 143 moves and abuts against the inner wall of the limit shell 14 to prevent the positioning rod 143 from blocking the waste chips when the ventilator 151 is blowing, so that the waste chips are not removed thoroughly. The hydraulic rod 4 158 is started to drive the protective plate 156 to move downward, thereby driving the ventilator 1 15 and the ventilator 2 151 to move downward. During the process, the protective plate 156 will block the rear side of the body shell 10, and the open end of the ventilator 2 151 presses down the ventilator 151 to push it downward until the ventilator 151 is closed. 1 is completely docked with the limiting shell 14. At this time, the fan 154 inside the ventilation tube 151 is started to blow air from the outside of the body shell 10 to the inside of the limiting shell 14, so that the waste chips inside the limiting shell 14 are blown to the inside of the docking tube 164 for recovery, and the two hydraulic rods 153 are started to drive the scraper 152 to move back and forth, and the two hydraulic rods 166 are started to drive the fixing frame 163 to drive the docking tube 164 to move upward. The top of the docking tube 164 moves the baffle 141 and pushes it to move upward until the docking tube 164 is aligned with the limiting shell 14, and the scraps adhering to the inner bottom surface of the limiting shell 14 are continuously scraped off by the scraper 152, and brought into the docking tube 164 under the action of the airflow, and then the waste chips fall into the collection cabinet 161 through the docking tube 164 for collection.
[0021] See also Figure 1 Two hydraulic rods 111 are fixedly connected to the front side of the body shell 10 , and the output ends of the hydraulic rods 111 are fixedly connected to the observation plate 11 .
[0022] During specific implementation, through the setting of the observation plate 11, it is possible to block and concentrate the soot in the working environment of the laser cutting mechanism 12, facilitating the centralized removal of the soot by the ventilation pipe 15 in cooperation with the fan 154. Synchronously starting the two hydraulic rods 111 can drive the observation plate 11 to be adjusted in the vertical direction, facilitating personnel operation.
[0023] Refer to Figures 3-5 , four sliders 1411 are slidably connected inside the limiting shell 14. The baffle 141 is fixedly connected to the adjacent slider 1411, and a first spring 1412 is fixedly connected between the slider 1411 and the limiting shell 14; A limiting plate 142 is fixedly connected to the top of the mounting plate 131. The limiting plate 142 passes through the limiting shell 14 and is slidably connected thereto. Four clamping rods 144 are fixedly connected to both inner walls of the limiting shell 14. The clamping rods 144 pass through the adjacent positioning rods 143 and are slidably connected thereto. Two second springs 1441 are fixedly connected between the positioning rods 143 and the limiting shell 14. The clamping rods 144 pass through the adjacent second springs 1441. Two one-way lead screws 146 are rotatably connected to both inner walls of the limiting shell 14. The adjacent two one-way lead screws 146 are symmetrically distributed. Two push plates 145 are slidably connected to both inner walls of the limiting shell 14. The one-way lead screws 146 pass through the adjacent push plates 145 and are threadedly connected thereto. Two double-shaft motors 147 are fixedly connected to both inner walls of the limiting shell 14. Both output ends of the double-shaft motor 147 are fixedly connected to the adjacent one-way lead screw 146; One end of the positioning rod 143 is arc-shaped; Two protective shells 148 are symmetrically fixedly connected to the top of the mounting plate 131. Two hydraulic rods 149 are fixedly connected to the inner walls of the protective shells 148. The output ends of the hydraulic rods 149 are fixedly connected to the outer wall of the limiting shell 14.
[0024] During specific implementation, the vertical sliding limit of the two baffles 141 is realized by the limit of the sliders 1411 by the limiting shell 14. The sliding ranges of the two baffles 141 are different. After placing the circuit board to be cut and processed on the top of the limiting plate 142, the hydraulic rod 149 is used to protect the protective shell 148. Starting multiple hydraulic rods 149 drives the overall upward movement of the limiting shell 14. After the top of the limiting shell 14 is higher than the limiting plate 142, at this time, the laser cutting mechanism 12 is used to process the circuit board on the top of the limiting plate 142. The generated waste chips will be blocked by the limiting shell 14 and splash into the limiting shell 14 for preliminary collection. During the process, multiple positioning rods 143 limit the four corners of the limiting plate 142, thereby preventing the circuit board from shifting; When it is necessary to clean the inside of the limit housing 14, the dual-axis motor 147 is started to drive the two unidirectional lead screws 146 to rotate, thereby driving the two push plates 145 to approach each other, separating the push plates 145 from the positioning rods 143. The positioning rods 143 slide under the reset action of the second spring 1441, so that the positioning rods 143 move to abut against the inner wall of the limit housing 14, preventing the positioning rods 143 from blocking the waste chips when the second ventilation cylinder 151 blows air, resulting in incomplete removal of the waste chips.
[0025] Refer to Figure 6 , two hydraulic rods three 153 are fixedly connected to the inner bottom surface of the second ventilation cylinder 151. The output ends of the hydraulic rods three 153 are fixedly connected to the scraper 152. Air blowers 154 are fixedly connected to the interiors of both the first ventilation cylinder 15 and the second ventilation cylinder 151. The orientations of the two air blowers 154 are opposite. A grid plate 155 is fixedly embedded at one end of the second ventilation cylinder 151; A protective plate 156 is slidably connected to the rear outer wall of the body housing 10. The first ventilation cylinder 15 and the second ventilation cylinder 151 penetrate through the protective plate 156 and are fixedly connected thereto. A sealing strip 157 is fixedly sleeved on the outer wall of the protective plate 156. Two hydraulic rods four 158 are fixedly connected to the rear outer wall of the body housing 10. The output ends of the hydraulic rods four 158 are fixedly connected to the protective plate 156. The top of the first ventilation cylinder 15 is fixedly communicated with an exhaust pipe 159.
[0026] During specific implementation, when the laser cutting mechanism 12 performs cutting and processing operations on the circuit board, the observation plate 11 seals the body housing 10, thereby concentrating the soot. Starting the air blower 154 inside the first ventilation cylinder 15 can timely extract the soot and discharge it through the exhaust pipe 159. After the laser cutting mechanism 12 finishes operating, start the hydraulic rod four 158 to drive the protective plate 156 to move downward, thereby driving the first ventilation cylinder 15 and the second ventilation cylinder 151 to move downward. During the process, the protective plate 156 will seal the rear side of the body housing 10. The open end of the second ventilation cylinder 151 presses down on the second ventilation cylinder 151 to push it downward until the second ventilation cylinder 151 is completely docked with the limit housing 14. At this time, starting the air blower 154 inside the second ventilation cylinder 151 can blow air from the outside of the body housing 10 into the limit housing 14, thereby blowing the waste chips inside the limit housing 14 into the docking cylinder 164 for recycling. And start the two hydraulic rods three 153 to drive the scraper 152 to reciprocate, continuously scraping the waste chips adhering to the inner bottom surface of the limit housing 14 by the scraper 152 and bringing them into the docking cylinder 164 under the action of the air flow.
[0027] Refer to Figure 7 , the recycling module 16 includes a collection cabinet 161. A limit frame 162 is fixedly connected to the inner bottom surface of the body housing 10. A docking cylinder 164 is slidably connected to the inside of the body housing 10. A filter screen 165 is fixedly embedded on one side of the docking cylinder 164; Inside the body housing 10, a fixing frame 163 is provided. The docking cylinder 164 passes through the fixing frame 163 and is fixedly connected thereto. Hydraulic rods five 166 are fixedly connected to both inner walls of the body housing 10. The output ends of the hydraulic rods five 166 are fixedly connected to the adjacent ends of the fixing frame 163. A clamping plate 167 is slidably connected to the front outer wall of the body housing 10. Two springs three 168 are fixedly connected between the clamping plate 167 and the body housing 10.
[0028] During specific implementation, after the laser cutting mechanism 12 finishes its operation, two hydraulic rods five 166 are started to drive the fixing frame 163 to drive the docking cylinder 164 to move upward. The top end of the docking cylinder 164 toggles the baffle plate 141 and pushes it upward until the docking cylinder 164 aligns with the limit shell 14. The fan 154 inside the ventilation cylinder two 151 blows external air into the limit shell 14 and blows the waste chips inside the limit shell 14 into the fan 154. Most of the convective air is discharged through the filter net 165. Then the waste chips fall into the collection cabinet 161 through the docking cylinder 164 for collection. The limit frame 162 is used to position the collection cabinet 161, and the clamping plate 167 is used to limit the collection cabinet 161, thereby preventing the collection cabinet 161 from detaching from the inside of the body housing 10 by itself. After lifting the clamping plate 167, the collection cabinet 161 can be slid out to centrally clean the waste chips inside the collection cabinet 161.
[0029] Working principle: During operation, the circuit board is placed on the limit plate 142. The hydraulic rod one 111 is started to drive the observation plate 11 to block the front side of the body housing 10. Multiple hydraulic rods two 149 are started to drive the limit shell 14 to move upward as a whole. After the top of the limit shell 14 is higher than the limit plate 142, at this time, the laser cutting mechanism 12 is used to process the circuit board on the top of the limit plate 142. The generated waste chips will be blocked by the limit shell 14 and splash into the limit shell 14 for preliminary collection. During the process, multiple positioning rods 143 limit the four corners of the limit plate 142 to prevent the circuit board from shifting. When the laser cutting mechanism 12 cuts and processes the circuit board, the observation plate 11 blocks the body housing 10 to concentrate the smoke and dust. Starting the fan 154 inside the ventilation cylinder one 15 can timely extract the smoke and dust and discharge it through the smoke exhaust pipe 159. After the laser cutting mechanism 12 has completed its operation, the dual-axis motor 147 is started to drive the two one-way screws 146 to rotate, thereby driving the two push plates 145 to move closer to each other, separating the push plates 145 from the positioning rod 143, and the positioning rod 143 slides under the reset action of the spring 1441, so that the positioning rod 143 moves and abuts against the inner wall of the limit shell 14 to prevent the positioning rod 143 from blocking the waste chips when the ventilator 151 is blowing, so that the waste chips are not removed thoroughly. The hydraulic rod 4 158 is started to drive the protective plate 156 to move downward, thereby driving the ventilator 1 15 and the ventilator 2 151 to move downward. During the process, the protective plate 156 will block the rear side of the body shell 10, and the open end of the ventilator 2 151 presses down the ventilator 151 to push it downward until the ventilator 151 is closed. 1 is completely docked with the limiting shell 14. At this time, the fan 154 inside the ventilation tube 151 is started to blow air from the outside of the body shell 10 to the inside of the limiting shell 14, so that the waste chips inside the limiting shell 14 are blown to the inside of the docking tube 164 for recovery, and the two hydraulic rods 153 are started to drive the scraper 152 to move back and forth, and the two hydraulic rods 166 are started to drive the fixing frame 163 to drive the docking tube 164 to move upward. The top of the docking tube 164 moves the baffle 141 and pushes it to move upward until the docking tube 164 is aligned with the limiting shell 14, and the scraps adhering to the inner bottom surface of the limiting shell 14 are continuously scraped off by the scraper 152, and brought into the docking tube 164 under the action of the airflow, and then the waste chips fall into the collection cabinet 161 through the docking tube 164 for collection.
