Description

Technical Field

[0001] The invention belongs to the technical field of laser printing, in particular to a laser printing device with an intelligent temperature control system. Background Art

[0002] Laser printing equipment is a device that uses laser technology to achieve functions such as marking and printing on the surface of objects. It emits a high-energy-density laser beam and focuses it on the surface of the object, causing the material to instantly absorb the laser energy, thereby forming clear and permanent text, patterns, logos or QR codes and other information. It has the advantages of high precision, fast speed, strong reliability and wide applicability.

[0003] In the existing technology, the laser marking machine uses a laser generator to generate a high-energy laser beam, which is then focused onto the surface of the object to be marked through an optical system. The computer control system controls the marking according to the pre-designed marking content. When the laser beam acts on the surface of the object, its high energy density causes the material to quickly absorb the laser energy, causing physical or chemical changes, thereby forming a permanent mark on the surface of the object.

[0004] The above solution still has some problems in practical application. Although the existing technology can complete the double-sided marking of window frames, as important components of buildings or doors and windows, the markings on window frames need to be clearly visible at different angles or in different environments to avoid information omissions due to installation direction or viewing angle. Therefore, double-sided marking is required for window frames. However, the marking head position of some marking machines on the market is fixed, and objects can only be marked from a single direction. This requires additional operations to complete the double-sided marking process, making the marking process cumbersome, extending the marking time of a single window frame, and thus reducing the marking efficiency. Secondly, since laser marking uses a high-energy-density laser beam to act on the surface of an object, causing the material to instantly melt, vaporize, or undergo chemical changes, thereby forming a permanent mark on the surface of the object, the material will undergo drastic physical and chemical changes during this process, and some of the material will fall off from the surface of the object in the form of tiny particles. In subsequent work, these tiny particles will scratch the surface of the object, thereby reducing the smoothness and flatness of the marked area and surrounding surfaces.

[0005] To this end, the present invention provides a laser printing device with an intelligent temperature control system. Summary of the Invention

[0009] Preferably, the rotating ratchet wheel is affected by the fixed ratchet bar to rotate when it rises. Since the fixed ratchet bar and the rotating ratchet wheel are both ratchet teeth structures, there will be no reversal when the rotating ratchet wheel descends.

[0010] Preferably, an L-shaped pressing block is fixedly connected to the bottom of the sliding block, a guide groove is provided on the upper portion of the workbench, a pressing hole is provided on the upper portion of the workbench, and a guide block is slidably connected inside the guide groove.

[0012] Preferably, the setting of the guide groove can ensure that the subsequent components maintain linear movement during the movement process, and the L-shaped lower pressure block is composed of a vertical rod and a transverse rod. One end of the transverse rod of the L-shaped lower pressure block has an oblique structure, and the inclination of the oblique structure of the L-shaped lower pressure block is adapted to the oblique structure of the oblique rod. The setting of the lower pressure hole facilitates the downward movement of the L-shaped lower pressure block.

[0014] Preferably, a downward-pressing cleaning mechanism for air jetting is provided on the side of the lifting and rotating mechanism, and the downward-pressing cleaning mechanism includes a fixed plate, which is fixedly connected to the side of the sliding block, and an air storage frame is fixedly connected to the upper part of the workbench, an inner cavity is opened inside the air storage frame, and a piston rod is slidably connected through the top of the air storage frame, a third spring is provided on the outer ring surface of the piston rod, and a piston plate is fixedly connected to the bottom of the piston rod.

[0015] Preferably, a second spring is fixedly connected to the bottom of the piston plate, one end of the second spring is fixedly connected to the bottom of the inner cavity of the air storage frame, an air inlet hole is opened through the bottom of one side of the air storage frame, an air guide tube is opened through and fixedly connected to the other side of the air storage frame, the other end of the air guide tube is opened through and fixedly connected to an injection block, an air outlet hole is opened through one side of the injection block, and the injection block is fixedly connected to the top of the placement table.

[0016] Preferably, the fixed plate will abut against the piston rod when it moves downward, and a one-way valve is provided inside the air inlet and the air outlet. The air outlet is an inclined spray hole, and the piston rod consists of a vertical rod and a cone sliding on the outer ring surface of the vertical rod. One end of the third spring is fixed to the outer ring surface of the piston rod cone, and the other end is fixed to the top of the air storage frame. A vertical rod with a cylindrical hole diameter larger than the piston rod is provided inside the fixed plate, and is on the same vertical plane as the piston rod vertical rod.

[0017] The beneficial effects of the present invention are as follows: 1. The laser printing device with an intelligent temperature control system described in the present invention, when the rotating ratchet wheel rises, it will drive the lower horizontal frame to flip over. When the side of the lower horizontal frame without marking is flipped to the top, the electric guide rail will move downward. Since the fixed ratchet bar and the rotating ratchet wheel are both ratchet structures, the rotating ratchet wheel does not engage with the teeth of the fixed ratchet bar when moving downward. At this time, the rotating ratchet wheel does not rotate. When the bottom surface of the lower horizontal frame contacts the upper part of the placement table, the rotating ratchet wheel will stop moving. Through the cooperation of the rotating ratchet wheel and the fixed ratchet wheel, the lower horizontal frame that needs double-sided marking can be flipped, thereby shortening the processing time of a single product and further improving the overall production efficiency.

[0018] When the two ends of the two first rotating rods are aligned with the planar surface of the second rotating rod, the other ends of the two first rotating rods will converge inwards, thereby driving the limiting columns fixed on the top thereof to perform synchronous convergence work. When the bottom of the lower horizontal frame contacts the top of the placing platform, it will contract. When the outer ring surfaces of the two limiting columns clamp the lower horizontal frame, the sliding block will stop moving. The downward pressing work of the L-shaped lower pressing block can drive the two limiting columns to converge, and at the same time, the lower horizontal frame can be limited, thereby improving the marking accuracy.

[0019] 3. The laser printing device with an intelligent temperature control system described in the present invention, when the second spring is compressed to the extreme, since the length of the vertical rod of the piston rod is greater than the height of the air storage frame, when the sliding block continues to press down, the piston rod will extend along the hole opened through the inside of the fixed plate, and the cone sliding on the outer ring surface of the vertical rod of the piston rod will move from the top of the vertical rod of the piston rod to the junction of the vertical rod and the top of the air storage frame. At this time, it is in a compressed state. Since its elasticity is greater than that of the second spring, when the fixed plate is pressed down, it can adapt to the overall operation of the lifting and rotating mechanism without affecting the air outlet to spray the placement table. At the same time, the air jet to the placement table can blow away the fine particles generated by the laser marking on the upper side, thereby preventing the particles from rolling and rubbing on the surface of the placement table or window frame, avoiding scratching the surface, and keeping the marking area and the surrounding surface smooth and flat.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] Example 1 like Figures 1 to 8 As shown, a laser printing device with an intelligent temperature control system according to an embodiment of the present invention includes a marking machine 1, wherein the marking machine 1 includes a workbench 101, a marking laser lamp 102 is provided on the top of the workbench 101, a placement table 103 is fixedly connected to the middle of the top of the workbench 101, and a lifting and rotating mechanism 2 is provided on the upper part of the marking machine 1; The lifting and rotating mechanism 2 includes a rotating ratchet 204 rotatably arranged on the upper part of the workbench 101, and a fixed ratchet bar 205 is engaged with the side of the rotating ratchet 204. The cooperation between the rotating ratchet 204 and the fixed ratchet bar 205 can drive the lower horizontal frame of the window frame to complete the flipping work.

[0024] Specifically, although the existing technology can complete the double-sided marking work of the window frame, the window frame is an important component of the building or doors and windows, and its markings need to be clearly visible at different angles or environments to avoid information omissions due to the installation direction or observation angle. Therefore, it is necessary to perform double-sided marking on the window frame. However, the marking head position of some marking machines 1 on the market is fixed, and the object can only be marked from a single direction. This requires additional operations to complete the double-sided marking work during the double-sided marking process, thereby making the marking process cumbersome, extending the marking time of a single window frame, and further reducing the efficiency of the marking work; Therefore, the present invention solves this problem by setting up a corresponding structure. The laser printing device with an intelligent temperature control system described in the present invention, when it is necessary to perform double-sided marking on the lower horizontal frame of the window frame, first place the lower horizontal frame on the placement table 103, and ensure that the marking area and the marking laser light 102 on the workbench 101 are consistent in the same vertical plane, and at the same time start the intelligent temperature control system to make the device work at a suitable temperature. At this time, start the placement table 103 to mark the surface of the lower horizontal frame. However, since the marking head position of some marking machines 1 on the market is fixed, objects can only be marked from a single direction, which will require additional operations to complete the double-sided marking process. The double-sided marking work is completed, which makes the marking process cumbersome, prolongs the marking time of a single window frame, and further reduces the efficiency of the marking work. At this time, the upward movement of the rotating ratchet 204 drives the synchronous upward movement of the lower horizontal frame. Since the rotating ratchet 204 and the fixed ratchet bar 205 are both ratchet structures, the rotating ratchet 204 is affected by the fixed ratchet bar 205 when it moves upward, and the rotating ratchet 204 rotates. When the first marking surface of the lower horizontal frame faces downward, the rotating ratchet 204 drives the lower horizontal frame to move downward. At this time, the rotating ratchet 204 does not rotate, thereby completing the flipping of the lower horizontal frame, reducing the complexity of the double-sided marking work, and thus improving production efficiency.

[0025] Example 2 like Figures 2 to 8 As shown in Comparative Example 1, another embodiment of the present invention is: like Figure 3 As shown, the lifting and rotating mechanism 2 described in this embodiment includes an electric guide rail 201, which is fixedly connected to the top of the workbench 101. A sliding block 202 is slidably connected inside the electric guide rail 201. The middle part of the sliding block 202 is rotatably connected to a first rotating shaft 203. One end of the first rotating shaft 203 is fixedly connected to a rotating ratchet 204. The fixed ratchet bar 205 is fixedly connected to the top of the workbench 101, and the side of the rotating ratchet 204 is fixedly connected to an electric telescopic rod 217.

[0026] Specifically, when the marking work on one side of the lower horizontal frame of the window frame is completed, the electric telescopic rod 217 is started to fix the two ends of the lower horizontal frame, and the electric guide rail 201 fixed on the top of the workbench 101 is started. When the electric guide rail 201 is started, it will drive the sliding block 202 sliding inside it to move linearly, and at the same time drive the first rotating shaft 203 and the rotating ratchet 204 to move synchronously. Since the rotating ratchet 204 is engaged with the fixed ratchet bar 205, the electric telescopic rod 217 will drive the lower horizontal frame to flip during the rising process of the rotating ratchet 204. When the lower horizontal frame is not marked, When one side is flipped to the top, the electric guide rail 201 will move downward. Since the fixed ratchet bar 205 and the rotating ratchet 204 are both ratchet structures, the rotating ratchet 204 does not engage with the teeth of the fixed ratchet bar 205 when it moves downward. At this time, the rotating ratchet 204 will not rotate. When the bottom surface of the lower horizontal frame contacts the upper part of the placement table 103, the rotating ratchet 204 will stop moving. Through the cooperation of the rotating ratchet 204 and the fixed ratchet bar 205, the lower horizontal frame that needs double-sided marking can be flipped, thereby shortening the processing time of a single product and thus improving the overall production efficiency.

[0027] like Figure 3 and Figure 5 As shown, the bottom of the sliding block 202 of this embodiment is fixedly connected to an L-shaped pressing block 206, the upper part of the workbench 101 is provided with a guide groove 210, the upper part of the workbench 101 is provided with a pressing hole 211, and the guide block 209 is slidably connected inside the guide groove 210.

[0028] like Figure 4 and Figure 5 As shown, in this embodiment, the top of the guide block 209 is fixedly connected to an oblique rod 207, one end of the oblique rod 207 is fixedly connected to a triangular block 208, the inclined surface of the triangular block 208 abuts against the first rotating rod 212, and a second rotating rod 213 is provided in the middle of the first rotating rod 212. The second rotating rod 213 is fixedly connected to the top of the workbench 101, and the first rotating rod 212 is rotatably connected to the outer ring surface of the second rotating rod 213.

[0029] like Figure 4 As shown, in this embodiment, the top of the other end of the first rotating rod 212 is fixedly connected to the limiting column 214, the side of the first rotating rod 212 is fixedly connected to the first spring 215, and the other end of the first spring 215 is fixedly connected to the fixed baffle 216, and the fixed baffle 216 is fixedly connected to the top of the workbench 101.

[0030] Specifically, when the sliding block 202 drives the L-shaped pressing block 206 to move downward, since the vertical rod length of the L-shaped pressing block 206 is greater than the radius length of the rotating ratchet 204, and the oblique structures of the L-shaped pressing block 206 and the oblique rod 207 are located on the same vertical plane, the oblique structure on the horizontal rod at the bottom of the L-shaped pressing block 206 will fit into the oblique structure at one end of the oblique rod 207. At this time, the L-shaped pressing block 206 will continue to move in the direction of the downward pressing hole 211, and at the same time, the oblique rod 207 is driven to move linearly along the guide of the guide groove 210 through the cooperation of the guide groove 210 and the guide block 209. Since the size of the downward pressing hole 211 is adapted to the size of the horizontal rod of the L-shaped pressing block 206, the L-shaped pressing block 206 will not be blocked when it continues to move downward. When the oblique rod 207 moves along the guide groove 210 toward the placement table 103, it will synchronously drive the triangular block 208 fixed at one end thereof to move synchronously. Since both sides of the triangular block 208 are oblique structures and one end of the two first rotating rods 212 is provided with an arc-shaped opening, when the triangular block 208 moves, it will continuously push the ends of the two first rotating rods 212 with openings to expand outward. Synchronously, since the first rotating rod 212 rotates on the outer ring surface of the second rotating rod 213, at this time the two first rotating rods 213 are connected to each other. The other end of the movable rod 212 will converge inward, thereby driving the limiting column 214 fixed on its top to perform synchronous convergence work. Since the electric telescopic rod 217 will contract when the bottom of the lower horizontal frame contacts the top of the placement table 103, the sliding block 202 will stop moving when the outer ring surface of the two limiting columns 214 clamps the lower horizontal frame. The downward pressing work of the L-shaped lower pressing block 206 can drive the two limiting columns 214 to converge, and at the same time, the lower horizontal frame can be limited, thereby improving the marking accuracy.

[0031] like Figure 8 As shown, the side of the lifting and rotating mechanism 2 in this embodiment is provided with a downward pressure cleaning mechanism 3 for air jetting, and the downward pressure cleaning mechanism 3 includes a fixed plate 301, and the fixed plate 301 is fixedly connected to the side of the sliding block 202. The upper part of the workbench 101 is fixedly connected to an air storage frame 305, and an inner cavity is opened inside the air storage frame 305. The top of the air storage frame 305 is slidably connected with a piston rod 302, and the bottom of the piston rod 302 is fixedly connected to a piston plate 303.

[0032] like Figure 7 and Figure 8As shown, the bottom of the piston plate 303 in this embodiment is fixedly connected to a second spring 304, one end of the second spring 304 is fixedly connected to the bottom of the inner cavity of the air storage frame 305, an air inlet hole 306 is opened through the bottom of one side of the air storage frame 305, an air guide tube 307 is opened through the other side of the air storage frame 305 and is fixedly connected, the other end of the air guide tube 307 is opened through and fixedly connected to an injection block 308, an air outlet hole 309 is opened through one side of the injection block 308, and the injection block 308 is fixedly connected to the top of the placement table 103.

[0033] Specifically, when the sliding block 202 moves downward, it will synchronously drive the fixed plate 301 fixed to its side to move synchronously. When the bottom of the fixed plate 301 contacts the top of the piston rod 302, the sliding block 202 will continue to move downward and squeeze the piston plate 303 through the piston rod 302 while moving. At this time, the air stored in the air storage frame 305 will flow into the jet block 308 through the air guide pipe 307 and spray the air to the surface of the placement table 103 through the inclined hole of the air outlet 309. At this time, the second spring 304 is in a contracted state, and the sliding block 202 will continue to move downward. When the second spring 304 is compressed to the extreme, since the vertical rod length of the piston rod 302 is greater than the height of the air storage frame 305, the sliding block 202 will continue to move downward. The plug rod 302 will extend along the hole opened through the inside of the fixed plate 301, and the cone sliding on the outer ring surface of the vertical rod of the piston rod 302 will move from the top of the vertical rod of the piston rod 302 to the junction of the vertical rod and the top of the gas storage frame 305. At this time, the third spring 310 is in a compressed state. Since the elasticity of the third spring 310 is greater than that of the second spring 304, when the fixed plate 301 is pressed down, it can not affect the air outlet 309 to spray the placement table 103 while also adapting to the overall operation of the lifting and rotating mechanism 2. At the same time, the air jet to the placement table 103 can blow away the fine particles generated by the laser marking on the upper side, thereby preventing the particles from rolling and rubbing on the placement table 103 or the window frame surface, avoiding scratching the surface, and keeping the marking area and the surrounding surface smooth and flat.

[0034] Working principle: when the marking work on one side of the lower horizontal frame of the window frame is completed, the electric telescopic rod 217 is started to fix the two ends of the lower horizontal frame, and the electric guide rail 201 fixed on the top of the workbench 101 is started. When the electric guide rail 201 is started, it will drive the sliding block 202 sliding inside it to move linearly, and at the same time drive the first rotating shaft 203 and the rotating ratchet 204 to move synchronously. Since the rotating ratchet 204 is engaged with the fixed ratchet bar 205, the electric telescopic rod 217 will drive the lower horizontal frame to flip during the rising process of the rotating ratchet 204. When the lower horizontal frame is not marked, When one side is flipped to the top, the electric guide rail 201 will move downward. Since the fixed ratchet bar 205 and the rotating ratchet 204 are both ratchet structures, the rotating ratchet 204 does not engage with the teeth of the fixed ratchet bar 205 when it moves downward. At this time, the rotating ratchet 204 will not rotate. When the bottom surface of the lower horizontal frame contacts the upper part of the placement table 103, the rotating ratchet 204 will stop moving. Through the cooperation of the rotating ratchet 204 and the fixed ratchet bar 205, the lower horizontal frame that needs double-sided marking can be flipped, thereby shortening the processing time of a single product and thus improving the overall production efficiency.

[0035] When the sliding block 202 drives the L-shaped pressing block 206 to move downward, since the vertical rod length of the L-shaped pressing block 206 is greater than the radius length of the rotating ratchet wheel 204, and the oblique structures of the L-shaped pressing block 206 and the oblique rod 207 are located on the same vertical plane, the oblique structure on the horizontal rod at the bottom of the L-shaped pressing block 206 will fit into the oblique structure at one end of the oblique rod 207. At this time, the L-shaped pressing block 206 will continue to move in the direction of the downward pressing hole 211, and at the same time, the oblique rod 207 is driven to move linearly along the guide of the guide groove 210 through the cooperation of the guide groove 210 and the guide block 209. Since the size of the downward pressing hole 211 is adapted to the size of the horizontal rod of the L-shaped pressing block 206, the L-shaped pressing block 206 will not be blocked when it continues to move downward. When the oblique rod 207 moves along the guide groove 210 toward the placement table 103, it will synchronously drive the triangular block 208 fixed at one end thereof to move synchronously. Since both sides of the triangular block 208 are oblique structures and one end of the two first rotating rods 212 is provided with an arc-shaped opening, when the triangular block 208 moves, it will continuously push the ends of the two first rotating rods 212 with openings to expand outward. Synchronously, since the first rotating rod 212 rotates on the outer ring surface of the second rotating rod 213, at this time the two first rotating rods 213 are connected to each other. The other end of the movable rod 212 will converge inward, thereby driving the limiting column 214 fixed on its top to perform synchronous convergence work. Since the electric telescopic rod 217 will contract when the bottom of the lower horizontal frame contacts the top of the placement table 103, the sliding block 202 will stop moving when the outer ring surface of the two limiting columns 214 clamps the lower horizontal frame. The downward pressing work of the L-shaped lower pressing block 206 can drive the two limiting columns 214 to converge, and at the same time, the lower horizontal frame can be limited, thereby improving the marking accuracy.

[0036] When the sliding block 202 moves downward, it will synchronously drive the fixed plate 301 fixed to its side to move synchronously. When the bottom of the fixed plate 301 contacts the top of the piston rod 302, the sliding block 202 will continue to move downward and squeeze the piston plate 303 through the piston rod 302 while moving. At this time, the air stored in the air storage frame 305 will flow into the jet block 308 through the air guide pipe 307 and spray the air to the surface of the placement table 103 through the inclined hole of the air outlet 309. At this time, the second spring 304 is in a contracted state, and the sliding block 202 will continue to move downward. When the second spring 304 is compressed to the extreme, since the vertical rod length of the piston rod 302 is greater than the height of the air storage frame 305, when the sliding block 202 continues to press downward, the piston rod 302 will extend along the hole opened through the inside of the fixed plate 301, and the cone sliding on the outer ring surface of the vertical rod of the piston rod 302 will move from the top of the vertical rod of the piston rod 302 to the junction of the vertical rod and the top of the gas storage frame 305. At this time, the third spring 310 is in a compressed state. Since the elasticity of the third spring 310 is greater than that of the second spring 304, when the fixed plate 301 is pressed down, it can not affect the air outlet 309 to spray the placement table 103 while also adapting to the overall operation of the lifting and rotating mechanism 2. At the same time, the air jet to the placement table 103 can blow away the fine particles generated by the laser marking on the upper side, thereby preventing the particles from rolling and rubbing on the placement table 103 or the window frame surface, avoiding scratching the surface, and keeping the marking area and the surrounding surface smooth and flat.
