Description

Technical Field

[0001] This invention belongs to the field of laser cutting machine technology, specifically a lens clamping mechanism for a laser cutting machine. Background Technology

[0002] Laser cutting machines use a high-power-density laser beam to irradiate the material being cut, quickly heating the material to its vaporization temperature and causing it to evaporate and form a hole. As the beam moves across the material, the hole continuously forms a very narrow kerf (such as about 0.1 mm), completing the cutting of the material. Laser cutting machines are now frequently used for cutting lenses.

[0003] However, the above technologies often have the following drawbacks: When cutting lenses, laser cutting machines are often used. In order to keep the lenses stable, a cumbersome fixing process is required to fix the lenses, which will affect the cutting efficiency of the lenses and cause the lens processing to be slow.

[0004] Therefore, the present invention provides a lens clamping mechanism for laser cutting machines. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a lens clamping mechanism for a laser cutting machine, comprising a main body of the equipment, a laser cutting component fixedly installed on the surface of the main body of the equipment, a support leg provided on the lower surface of the main body of the equipment, a motor fixedly installed on the surface of the main body of the equipment, the output end of the motor passing through the bottom plate of the main body of the equipment and fixedly installed on a placement plate, a pair of fixing grooves opened on the surface of the placement plate, a lens body disposed inside the fixing grooves, a set of movable grooves opened on the surface of the placement plate, a fixing sleeve slidably installed on the inner wall of each movable groove, a spring strip fixedly installed on the surface of each fixing sleeve, and the other end of the spring strip fixedly connected to the inner wall of the movable groove;

[0007] Lenses are often cut using laser cutting machines. To maintain lens stability, a cumbersome fixing process is required, which affects cutting efficiency and slows down lens processing. The laser cutting machine of this invention, when cutting a lens, pulls a fixing sleeve to the end away from the placement plate. During this movement, the fixing sleeve stretches a spring, placing the lens body into a fixing groove. Releasing the fixing sleeve causes the spring to reset, securing the lens body within the movable groove. This rapid fixation of the lens body improves cutting efficiency. The motor is then started, and its output shaft rotates, causing the placement plate to rotate. This rotation transports the lens body to the laser cutting assembly for cutting. Because the placement plate has a pair of fixing grooves, the cut lens is removed from the end of the placement plate away from the main body of the machine, and an unprocessed lens is repositioned, further saving processing time and improving cutting efficiency.

[0008] Preferably, a fixing frame is fixedly installed on the surface of the placement plate, and a glue tube is fixedly installed on the surface of the fixing frame. Hot melt adhesive is disposed inside the glue tube, and a piston rod is slidably installed on the inner wall of the glue tube. An elastic element is disposed at the end of the piston rod away from the fixing sleeve, and the other end of the elastic element is fixedly connected to the inner wall of the glue tube. A guide tube is fixedly installed on the surface of the glue tube, with the end of the guide tube away from the glue tube located above the fixing sleeve. During the pulling motion of the fixing sleeve, the fixing sleeve contacts the piston rod and drives the piston rod to move, squeezing the elastic element. When the piston rod moves, it squeezes the hot melt adhesive inside the glue tube. The hot melt adhesive is sprayed along the guide tube towards the inner side of the fixing sleeve and adheres to the inner side of the fixing sleeve. When the fixing sleeve returns to its original position, the hot melt adhesive contacts the lens body. After the hot melt adhesive cools, it adheres to the lens body, thereby improving the fixing effect of the fixing sleeve when fixing the lens body. When the fixing sleeve is away from the piston rod, the elastic element drives the piston rod to return to its original position.

[0009] Preferably, a protective pad is fixedly installed on the surface of the fixing sleeve, and the protective pad is made of sponge; when the guide tube sprays hot melt adhesive, the hot melt adhesive will be sprayed onto the protective pad, and the hot melt adhesive will be absorbed by the sponge material of the protective pad and spread within it. When the protective pad squeezes the lens body, the hot melt adhesive overflows and makes uniform contact with the lens body, thereby further improving the fixing effect of the lens body.

[0010] Preferably, a fixing ring is fixedly installed on the surface of the fixing frame, and a threaded rod is threadedly connected to the inner wall of the fixing ring. A replenishment bucket is provided inside the fixing ring, and a connecting pipe is fixedly installed on the surface of the replenishment bucket. The connecting pipe is connected to the inside of the glue cylinder, and a one-way valve is provided on the inner wall of both the connecting pipe and the guide pipe. When the piston rod resets, the one-way valve in the guide pipe closes, the glue cylinder is in a sealed state and a negative pressure is generated. The negative pressure guides the hot melt adhesive in the replenishment bucket into the glue cylinder through the connecting pipe (when the piston rod squeezes the glue cylinder, the one-way valve in the connecting pipe is closed), which can quickly replenish the hot melt adhesive, thereby improving the efficiency of fixing the lens body. After the hot melt adhesive in the replenishment bucket is used up, the threaded rod is rotated to release the fixation of the replenishment bucket, and the replenishment bucket can be removed and replaced. Rotating the threaded rod in the opposite direction causes the threaded rod to move and abut against the replenishment bucket, fixing the replenishment bucket, further improving the efficiency of the equipment during use.

[0011] Preferably, a rotating pad is rotatably mounted on the end of the threaded rod near the refill container. The rotating pad is made of rubber material. The threaded rod drives the rotating pad to move during the process of fixing the refill container. When the rotating pad comes into contact with the refill container, the rotating pad stops rotating, and the threaded rod rotates inside the rotating pad, so as to avoid the threaded rod coming into contact with the refill container when rotating, which would cause damage to the refill container.

[0012] Preferably, a recycling pipe is fixedly installed on the surface of the replenishment tank, and a recycling pad is fixedly installed at the end of the recycling pipe away from the replenishment tank. The recycling pad is cone-shaped and located below the guide pipe. When hot melt adhesive is sprayed from the guide pipe, if the amount of hot melt adhesive is large, it will drip from the protective pad. The dripping hot melt adhesive falls into the cone-shaped recycling pad and enters the replenishment tank along the recycling pipe, thereby avoiding contamination caused by hot melt adhesive dripping and avoiding waste of hot melt adhesive.

[0013] Preferably, an air pipe is fixedly installed on the surface of the main body of the device. The air pipe is connected to an external fan. A guide pipe is fixedly installed on the surface of the air pipe, with the end of the guide pipe away from the air pipe facing the protective pad. When the hot melt adhesive is sprayed onto the protective pad, the fan is turned on, and the fan blows air into the air pipe and along the guide pipe toward the protective pad. This allows the hot melt adhesive to cool and dry quickly after the protective pad fixes the lens body, improving the efficiency of the hot melt adhesive in fixing the lens body.

[0014] Preferably, the surface of the air tube is provided with a transfer box, and the inner wall of the transfer box is provided with a cooling chip (the cooling chip is a semiconductor cooling chip with a cooling surface and a heat dissipation surface), and the cooling surface of the cooling chip faces the air tube; the cooling chip can cool the air passing through the transfer box, so that the air blown toward the protective pad is low temperature air, thereby further accelerating the cooling and drying of the hot melt adhesive and improving the effect of fixing the lens body.

[0015] Preferably, a movable rod is fixedly installed on the heat dissipation surface of the cooling element, an electromagnet is fixedly installed on the surface of the movable rod, a spring is fixedly installed on the surface of the electromagnet, and the other end of the spring is fixedly connected to the surface of the transfer box. When the electromagnet is energized, it attracts the transfer box. When disassembling the lens body, the electromagnet is turned on, and the electromagnet generates magnetism, attracting the transfer box and moving towards the transfer box. When the electromagnet moves, it drives the movable rod to move, and the movable rod drives the cooling element to move inside the transfer box. When the cooling surface of the cooling element contacts the inner wall of the transfer box, the heat dissipation surface of the cooling element faces the air pipe, heating the air passing through the transfer box. The heated air is blown towards the protective pad, causing the hot melt adhesive to melt. After the hot melt adhesive melts, the lens body can be easily disassembled.

[0016] Preferably, a protective film is fixedly installed on the surface of the air duct, and a set of shrinkage holes are provided on the surface of the protective film. When air is ejected from the air duct, the protective film first expands and becomes arc-shaped. The shrinkage holes on its surface open and spray towards the protective pad, thereby improving the efficiency of the hot melt adhesive cooling and melting. After the protective film is reset, it can block the air duct, thereby achieving the effect of protecting the air duct.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The present invention provides a lens clamping mechanism for a laser cutting machine. When the laser cutting machine cuts a lens, it pulls a fixing sleeve to move away from the placement plate. During this movement, the fixing sleeve stretches a spring, placing the lens body into a fixing groove. The fixing sleeve is then released, and the spring causes the fixing sleeve to reset. As the fixing sleeve resets in the movable groove, it secures the lens body, thus quickly fixing it and improving the cutting efficiency. The motor is then started, and its output shaft rotates, causing the placement plate to rotate. As the placement plate rotates, it transports the lens body to the laser cutting assembly for cutting. Because the surface of the placement plate has a pair of fixing grooves, the cut lens is removed from the end of the placement plate away from the main body of the machine, and an unprocessed lens is repositioned, further saving processing time and improving cutting efficiency.

[0019] 2. In the laser cutting machine lens clamping mechanism of the present invention, during the movement of the fixed sleeve, the fixed sleeve contacts the piston rod and drives the piston rod to move and squeeze the elastic element. When the piston rod moves, it squeezes the hot melt adhesive in the glue tube. The hot melt adhesive is sprayed along the guide tube to the inside of the fixed sleeve and adheres to the inside of the fixed sleeve. When the fixed sleeve is reset, the hot melt adhesive contacts the lens body. After the hot melt adhesive cools, it sticks the lens body, thereby improving the fixing effect of the fixed sleeve when fixing the lens body. When the fixed sleeve is away from the piston rod, the elastic element drives the piston rod to reset. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] Example 1: As Figures 1 to 6As shown in the figure, a laser cutting machine lens clamping mechanism according to an embodiment of the present invention includes a device body 1, a laser cutting component 3 fixedly installed on the surface of the device body 1, a support leg 2 provided on the lower surface of the device body 1, a motor 4 fixedly installed on the surface of the device body 1, the output end of the motor 4 passing through the bottom plate of the device body 1 and fixedly installed on a placement plate 5, a pair of fixing grooves 6 opened on the surface of the placement plate 5, a lens body 31 disposed inside the fixing grooves 6, a set of movable grooves 8 opened on the surface of the placement plate 5, a fixing sleeve 7 slidably installed on the inner wall of each movable groove 8, a spring strip 9 fixedly installed on the surface of each fixing sleeve 7, and the other end of the spring strip 9 fixedly connected to the inner wall of the movable groove 8;

[0031] Lenses are often cut using laser cutting machines. To maintain lens stability during cutting, a cumbersome fixing process is required before cutting, which affects cutting efficiency and slows down processing. In this invention, the laser cutting machine pulls the fixing sleeve 7 away from the placement plate 5 during cutting. As the fixing sleeve 7 moves, the elastic bar 9 stretches, placing the lens body 31 into the fixing groove 6. The fixing sleeve 7 is then released, and the elastic bar 9 drives the fixing sleeve 7 to reset. When the fixing sleeve 7 resets in the movable groove 8, it fixes the lens body 31, thus quickly fixing it and improving cutting efficiency. The motor 4 is then started, and its output shaft rotates, driving the placement plate 5 to rotate. As the placement plate 5 rotates, it transports the lens body 31 to the laser cutting assembly 3 for cutting. Because the surface of the placement plate 5 has a pair of fixing grooves 6, the cut lens is removed from the end of the placement plate 5 away from the main body 1, and the unprocessed lens is repositioned, further saving processing time and improving cutting efficiency.

[0032] A fixing frame 10 is fixedly mounted on the surface of the placement plate 5. A glue tube 11 is fixedly mounted on the surface of the fixing frame 10. Hot melt adhesive is disposed inside the glue tube 11. A piston rod 12 is slidably mounted on the inner wall of the glue tube 11. An elastic element is provided at one end of the piston rod 12 away from the fixing sleeve 7. The other end of the elastic element is fixedly connected to the inner wall of the glue tube 11. A guide tube 13 is fixedly mounted on the surface of the glue tube 11. The end of the guide tube 13 away from the glue tube 11 is located above the fixing sleeve 7. Pulling the fixing sleeve 7 moves the glue tube 11. During the process, the fixing sleeve 7 contacts the piston rod 12 and drives the piston rod 12 to move and squeeze the elastic element. When the piston rod 12 moves, it squeezes the hot melt adhesive in the glue tube 11. The hot melt adhesive is sprayed along the guide tube 13 to the inside of the fixing sleeve 7 and adheres to the inside of the fixing sleeve 7. When the fixing sleeve 7 is reset, the hot melt adhesive contacts the lens body 31. After the hot melt adhesive cools, it sticks the lens body 31, thereby improving the fixing effect of the fixing sleeve 7 when fixing the lens body 31. When the fixing sleeve 7 is away from the piston rod 12, the elastic element drives the piston rod 12 to reset.

[0033] A protective pad 14, made of sponge, is fixedly installed on the surface of the fixing sleeve 7. When the guide tube 13 sprays hot melt adhesive, the hot melt adhesive will be sprayed onto the protective pad 14. The hot melt adhesive is absorbed by the sponge material of the protective pad 14 and spreads within it. When the protective pad 14 squeezes the lens body 31, the hot melt adhesive overflows and contacts the lens body 31 evenly, thereby further improving the fixing effect of the lens body 31.

[0034] A fixing ring 15 is fixedly installed on the surface of the fixing frame 10. A threaded rod 18 is threadedly connected to the inner wall of the fixing ring 15. A replenishment tank 16 is provided inside the fixing ring 15. A connecting pipe 17 is fixedly installed on the surface of the replenishment tank 16. The connecting pipe 17 is connected to the inside of the glue cylinder 11. One-way valves are provided on the inner walls of both the connecting pipe 17 and the guide pipe 13. When the piston rod 12 is reset, the one-way valve in the guide pipe 13 is closed, the glue cylinder 11 is in a sealed state and a negative pressure is generated. The negative pressure pushes the hot melt adhesive in the replenishment tank 16. The hot melt adhesive can be quickly replenished by guiding it into the glue cylinder 11 through the connecting pipe 17 (when the piston rod 12 squeezes the glue cylinder 11, the one-way valve in the connecting pipe 17 is closed), thereby improving the efficiency of fixing the lens body 31. After the hot melt adhesive in the replenishment tank 16 is used up, the threaded rod 18 can be rotated to release the fixation of the replenishment tank 16, and the replenishment tank 16 can be removed and replaced. Rotating the threaded rod 18 in the opposite direction will cause the threaded rod 18 to move and abut against the replenishment tank 16, fixing the replenishment tank 16, further improving the efficiency of the equipment during use.

[0035] A rotating pad 19, made of rubber, is rotatably mounted on one end of the threaded rod 18 near the replenishment container 16. During the process of fixing the replenishment container 16, the threaded rod 18 drives the rotating pad 19 to move. When the rotating pad 19 contacts the replenishment container 16, the rotating pad 19 stops rotating, and the threaded rod 18 rotates within the rotating pad 19, thus avoiding contact between the threaded rod 18 and the replenishment container 16 during rotation, which could cause damage to the replenishment container 16.

[0036] A recycling pipe 21 is fixedly installed on the surface of the replenishment tank 16. A recycling pad 20 is fixedly installed at the end of the recycling pipe 21 away from the replenishment tank 16. The recycling pad 20 is conical and located below the guide pipe 13. When hot melt adhesive is sprayed from the guide pipe 13, if the amount of hot melt adhesive is large, it will drip from the protective pad 14. The dripping hot melt adhesive falls into the conical recycling pad 20 and enters the replenishment tank 16 along the recycling pipe 21, thereby avoiding contamination caused by hot melt adhesive dripping and avoiding waste of hot melt adhesive.

[0037] An air pipe 22 is fixedly installed on the surface of the main body 1 of the device. The air pipe 22 is connected to an external fan. A guide pipe 23 is fixedly installed on the surface of the air pipe 22. The end of the guide pipe 23 away from the air pipe 22 faces the protective pad 14. When the hot melt adhesive is sprayed onto the protective pad 14, the fan is turned on. The fan blows air into the air pipe 22 and along the guide pipe 23 toward the protective pad 14. This allows the hot melt adhesive to cool and dry quickly after the protective pad 14 fixes the lens body 31, improving the efficiency of the hot melt adhesive in fixing the lens body 31.

[0038] The surface of the air tube 22 is provided with a transfer box 24, and the inner wall of the transfer box 24 is provided with a cooling chip 25 (the cooling chip 25 is a semiconductor cooling chip 25, which has a cooling surface and a heat dissipation surface). The cooling surface of the cooling chip 25 faces the air tube 22. The cooling chip 25 can cool the air passing through the transfer box 24, so that the air blown toward the protective pad 14 is low temperature air, thereby further accelerating the cooling and drying of the hot melt adhesive and improving the effect of fixing the lens body 31.

[0039] A movable rod 26 is fixedly installed on the heat dissipation surface of the cooling element 25. An electromagnet 27 is fixedly installed on the surface of the movable rod 26, and a spring 28 is fixedly installed on the surface of the electromagnet 27. The other end of the spring 28 is fixedly connected to the surface of the transfer box 24. When the electromagnet 27 is energized, it attracts the transfer box 24. When the lens body 31 is disassembled, the switch of the electromagnet 27 is turned on. The electromagnet 27 generates magnetism and attracts the transfer box 24 and moves in the direction of the transfer box 24. When the electromagnet 27 moves, it drives the movable rod 26 to move. The movable rod 26 drives the cooling element 25 to move inside the transfer box 24. When the cooling surface of the cooling element 25 contacts the inner wall of the transfer box 24, the heat dissipation surface of the cooling element 25 faces the air pipe 22 and heats the air passing through the transfer box 24. The heated air is blown toward the protective pad 14, causing the hot melt adhesive to melt. After the hot melt adhesive melts, it is easy to disassemble the lens body 31.

[0040] Example 2: Figure 7 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a protective film 29 is fixedly installed on the surface of the air guide duct 23, and a set of shrinkage holes 30 are provided on the surface of the protective film 29; when the air guide duct 23 sprays out air, the protective film 29 first expands, and the protective film 29 expands into an arc shape, and the shrinkage holes 30 on its surface open, spraying towards the protective pad 14, thereby improving the efficiency of hot melt adhesive cooling and melting. After the protective film 29 is reset, it can block the air guide duct 23, thereby achieving the effect of protecting the air guide duct 23.

[0041] Working principle: When the laser cutting machine cuts the lens, it pulls the fixing sleeve 7 to move away from the placement plate 5. As the fixing sleeve 7 moves, it stretches the spring strip 9, placing the lens body 31 into the fixing groove 6. Releasing the fixing sleeve 7 causes the spring strip 9 to reset the fixing sleeve 7. When the fixing sleeve 7 resets in the movable groove 8, it fixes the lens body 31, thus quickly fixing the lens body 31 and improving the cutting efficiency. Then, the motor 4 is started, and the output shaft of the motor 4 rotates, driving the placement plate 5 to rotate. As the placement plate 5 rotates, it transports the lens body 31 to the area below the laser cutting assembly 3 for cutting. Because the surface of the placement plate 5 has a pair of fixing grooves 6, the placement plate 5 is then removed and moved away from the main equipment. The cut lens is placed in one end of the body 1 and the unprocessed lens is placed in it, thereby further saving processing time and improving cutting efficiency. During the movement of the fixed sleeve 7, the fixed sleeve 7 contacts the piston rod 12 and drives the piston rod 12 to move and squeeze the elastic element. When the piston rod 12 moves, it squeezes the hot melt adhesive in the glue tube 11. The hot melt adhesive is sprayed along the guide tube 13 to the inside of the fixed sleeve 7 and adheres to the inside of the fixed sleeve 7. When the fixed sleeve 7 is reset, the hot melt adhesive contacts the lens body 31. After the hot melt adhesive cools, it sticks the lens body 31, thereby improving the fixing effect of the fixed sleeve 7 when fixing the lens body 31. When the fixed sleeve 7 is away from the piston rod 12, the elastic element drives the piston rod 12 to reset.

[0042] When the guide tube 13 sprays hot melt adhesive, the adhesive is sprayed onto the protective pad 14. The hot melt adhesive is absorbed by the sponge-material protective pad 14 and spreads within it. When the protective pad 14 presses against the lens body 31, the hot melt adhesive overflows and evenly contacts the lens body 31, thereby further improving the fixing effect of the lens body 31. When the piston rod 12 resets, the one-way valve in the guide tube 13 closes, the glue cylinder 11 is sealed and generates negative pressure. The negative pressure guides the hot melt adhesive in the replenishment container 16 through the connecting tube 17 into the glue cylinder 11 (when the piston rod 12 presses against the glue cylinder 11, the one-way valve in the connecting tube 17 is closed), which can quickly replenish the hot melt adhesive, thereby improving the fixing effect. The efficiency of the fixed lens body 31 is improved. After the hot melt adhesive in the replenishment canister 16 is used up, the threaded rod 18 is rotated to release the fixation of the replenishment canister 16, and the replenishment canister 16 can be removed and replaced. The threaded rod 18 is rotated in the opposite direction, and the threaded rod 18 moves against the replenishment canister 16 to fix the replenishment canister 16, which further improves the efficiency of the equipment during use. During the process of fixing the replenishment canister 16, the threaded rod 18 drives the rotating pad 19 to move. When the rotating pad 19 contacts the replenishment canister 16, the rotating pad 19 stops rotating, and the threaded rod 18 rotates inside the rotating pad 19 to avoid the threaded rod 18 contacting the replenishment canister 16 during rotation, which would cause damage to the replenishment canister 16.

[0043] When hot melt adhesive is sprayed from the guide tube 13, if the amount of hot melt adhesive is large, it will drip from the protective pad 14. The dripping hot melt adhesive falls into the cone-shaped recycling pad 20 and enters the replenishment bucket 16 along the recycling tube 21, thus avoiding contamination caused by hot melt adhesive dripping and avoiding waste of hot melt adhesive. After the hot melt adhesive is sprayed on the protective pad 14, the fan is turned on. The fan blows air into the air pipe 22 and blows it along the air guide 23 towards the protective pad 14. After the protective pad 14 fixes the lens body 31, the hot melt adhesive cools and dries quickly, improving the efficiency of the hot melt adhesive in fixing the lens body 31. The cooling plate 25 can cool the air passing through the transfer box 24, so that the air blown towards the protective pad 14 is low temperature air, thereby further accelerating the cooling and drying of the hot melt adhesive and improving the effect of fixing the lens body 31.

[0044] When disassembling the lens body 31, the switch of electromagnet 27 is turned on. Electromagnet 27 generates magnetism and attracts the transfer box 24, moving towards the transfer box 24. When electromagnet 27 moves, it drives the movable rod 26 to move. The movable rod 26 drives the cooling plate 25 to move inside the transfer box 24. When the cooling surface of the cooling plate 25 contacts the inner wall of the transfer box 24, the heat dissipation surface of the cooling plate 25 faces the air pipe 22, heating the air passing through the transfer box 24. The heated air is blown towards the protective pad 14, causing the hot melt adhesive to melt. After the hot melt adhesive melts, it is easy to disassemble the lens body 31. When the air duct 23 sprays air, it first causes the protective film 29 to expand. After the protective film 29 expands, it becomes arc-shaped, and the shrinkage holes 30 on its surface open, spraying towards the protective pad 14, thereby improving the efficiency of the hot melt adhesive cooling and melting. After the protective film 29 is reset, it can block the air duct 23, thereby protecting the air duct 23.
