Description

Technical Field

[0001] This invention relates to the field of laser marking, specifically to a vision-based three-axis laser marking machine with recyclable material feeding. Background Technology

[0002] Visual three-axis laser marking uses a laser beam to create permanent marks on the surfaces of various materials. The marking effect is achieved by evaporating the surface material to expose the deeper material, by causing chemical and physical changes in the surface material through light energy to "etch" a mark, or by burning away part of the material to reveal the desired pattern or text. Currently, laser marking machines are mainly used in applications requiring higher precision or for the outer surfaces of products, such as electronic components, integrated circuits (ICs), electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, eyeglasses and watches, jewelry, automotive parts, plastic buttons, building materials, PVC pipes, temperature switch controllers, and other products.

[0003] The advantages of laser marking include: non-contact operation, no cutting force, and minimal heat-affected zone, ensuring the original precision of the workpiece. It is particularly suitable for industries requiring high precision. The laser marking process is highly flexible, and the use of automated marking lines can meet the requirements of large-scale industrial production. Laser engraving can achieve fine lines at the meter to micrometer level. Marks made using laser marking technology are extremely difficult to counterfeit and alter, making them crucial for product anti-counterfeiting. The combination of laser processing systems and computer numerical control technology can form automated processing equipment that can print various texts, symbols, and patterns. It is easy to design marking patterns and modify marking content using software, adapting to the fast pace of modern production. Compared to traditional inkjet printing, laser processing is a green and environmentally friendly processing technology with no pollution source. It has a wide range of material adaptability, can mark extremely fine marks on the surface of various materials, and has very high durability.

[0004] However, existing vision-based three-axis laser marking machines require manual placement of the temperature switch controller on the conveyor belt surface. Furthermore, the temperature switch controller must be rotated to a uniform orientation to prevent labels from being applied to other parts of the controller, thus affecting product sales. The conveyor belt then transports the product to the area below the laser head, allowing the laser head to mark the product surface. Therefore, workers need to continuously place products on the conveyor belt surface to achieve continuous marking. Consequently, existing vision-based three-axis laser marking machines are not suitable for automatic, cyclical product feeding. Summary of the Invention

[0005] The purpose of this invention is to provide a vision-based three-axis laser marking machine with recirculating feeding, which solves the following technical problems: the vision-based three-axis laser marking machine automatically feeds products in a recirculating manner, realizing automatic continuous marking processing of products.

[0006] The objective of this invention can be achieved through the following technical solution: a recyclable three-axis laser marking machine, comprising: a laser marking mechanism and a feeding mechanism, wherein the feeding mechanism is fixedly installed at the top end of the laser marking mechanism; the interior of the feeding mechanism includes a feeding section and a discharging section, wherein the discharging section is fixedly installed at the bottom end of the feeding section;

[0008] The discharge section is internally equipped with a second support frame. A discharge shaft is rotatably engaged at the top center of the second support frame. Discharge plates are uniformly fixedly connected to the outer surface of the discharge shaft. A material feeding shaft is rotatably engaged at the top of the second support frame and on one side of the discharge shaft. A drive shaft is rotatably engaged at the top of the second support frame and on the other side of the discharge shaft. Second transmission sprockets are fixedly installed at both ends of the discharge shaft and the drive shaft. First transmission sprockets are fixedly installed at both ends of the material feeding shaft and the discharge shaft. A first transmission chain is meshed with the outer surfaces of the first and second transmission sprockets. A second transmission chain is meshed with the outer surface of one end of the discharge shaft. A drive motor is fixedly installed at the top of the second support frame and at one end of the drive shaft.

[0009] As a further aspect of the present invention: a support frame is welded to the four corners of the bottom surface of the product feeding hopper, a discharge port is opened at the center of the bottom surface of the product feeding hopper, a winding reel is fixedly installed at the end of the transmission shaft away from the second transmission gear, a connecting rope is fixedly connected to the outer surface of the winding reel, and a counterweight is fixedly connected to the bottom end of the connecting rope.

[0010] As a further aspect of the present invention: a first support frame is fixedly installed inside the laser marking mechanism, a conveyor belt is rotatably installed on the top of the first support frame, a collection box is provided at one end of the first support frame, a pouring plate is provided on the top of the first support frame and at one end of the conveyor belt, a protrusion is provided inside the end of the conveyor belt away from the pouring plate, a display is fixedly installed on the side of the first support frame, and a laser head is movably installed on the side of the first support frame and at the edge of the display.

[0011] As a further aspect of the present invention: the side of the counterweight block is slidably engaged with one end face of the second support frame, the transmission shafts are rotatably connected to each other through the first transmission gear, and the gear shaft is meshed with the second transmission gear through a half gear.

[0012] As a further aspect of the present invention: the feeding shaft is rotatably connected to the gear shaft via a second transmission chain, the feeding shaft is rotatably connected to the drive shaft via a first transmission chain, and the drive motor is rotatably connected to one end of the conveyor belt via the drive shaft.

[0013] As a further embodiment of the present invention: the drive spindle is rotatably connected to both ends of the feeding shaft via a first transmission chain, the feeding shaft is uniformly provided with L-shaped feeding plates on its outer surface, and the feeding shaft is rotatably engaged with the center of the discharge port via the feeding feeding plate in the middle.

[0014] As a further embodiment of the present invention: the limiting inclined plate is inclined inside the product feeding hopper, and the discharge port is aligned with one end of the upper surface of the conveyor belt.

[0015] As a further aspect of the present invention: the weight of the counterweight is twice the weight of the product inside the top of the product feeding hopper, and one end of the drive spindle is fixedly connected to one end of the drive motor.

[0016] The beneficial effects of this invention are:

[0017] (1) By setting a discharge section at one end of the laser marking mechanism and controlling the drive motor to rotate, the present invention enables the flip plate to deflect downward intermittently in the product feeding hopper, thereby discharging the product intermittently downward. Moreover, the discharge shaft will rotate and transport the falling product through the discharge deflector plate on the outer surface, discharging the product onto the upper surface of the conveyor belt, thereby achieving the purpose of circulating the product inside the product feeding hopper.

[0018] (2) By setting a winding reel and a counterweight at one end of the transmission shaft, the present invention enables the counterweight to provide power for the resetting and flipping of the flipping plate under the action of gravity, thereby ensuring that the flipping plate provides stable support for the product inside the product feeding hopper. Therefore, when the half gear drives the second transmission gear to deflect intermittently, the flipping plate can discharge material intermittently inside the product feeding hopper, thereby avoiding the product from accumulating at the bottom of the product feeding hopper and hindering the normal rotation of the feeding plate. Therefore, by circulating and discharging the product in small quantities, a stable circulating material supply to the upper surface of the conveyor belt can be ensured.

[0019] (3) By setting a material-pushing shaft at the top of the conveyor belt, the bottom side of the product will be lifted when the product passes over the protrusion. At the same time, the L-shaped plate on the outer surface of the material-pushing shaft will rotate and push the product side to flip, so that the top of the product is facing upward. When the top of the product passes over the top of the protrusion, it will not contact the L-shaped plate on the outer surface of the material-pushing shaft, thus preventing the product from being blocked by the conveyor belt. At the same time, it avoids the need for manual flipping of the products one by one, thereby improving the efficiency of marking the top of the product. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-7 As shown, the present invention is a vision three-axis laser marking machine with recyclable material supply, including: a laser marking mechanism 1 and a feeding mechanism 2, wherein the feeding mechanism 2 is fixedly installed at the top end of the laser marking mechanism 1; the feeding mechanism 2 includes a feeding part 21 and a discharging part 22 inside, wherein the discharging part 22 is fixedly installed at the bottom end of the feeding part 21.

[0031] The feeding section 21 is equipped with a product feeding hopper 212. Both sides of the product feeding hopper 212 are equipped with limiting inclined plates 213. The product feeding hopper 212 is symmetrically and rotatably mounted with a transmission shaft 2113. A first transmission gear 219 is fixedly mounted on the outer surface of one end of the transmission shaft 2113. A flipping plate 214 is fixedly connected to the outer surface of the middle part of the transmission shaft 2113. A second transmission gear 2112 is fixedly connected to one end of the transmission shaft 2113. A gear shaft 2110 is rotatably engaged at one end of the product feeding hopper 212 and at the bottom of the second transmission gear 2112. A half gear 2111 is fixedly connected to one end of the gear shaft 2110. The upper surface of the side end of the flipping plate 214 overlaps with the bottom side end of the limiting inclined plate 213.

[0032] Through the above technical solution, the second transmission gear 2112 can rotate intermittently with small amplitude under the drive of the half gear 2111. Since the transmission shafts 2113 are connected by the meshing of the first transmission gear 219, the two sets of tilting plates 214 will rotate synchronously in opposite directions inside the product feeding hopper 212, and at the same time discharge the product on the upper surface intermittently, thereby ensuring that the product falls smoothly onto the upper surface of the conveyor belt 11.

[0033] The discharge section 22 is internally equipped with a second support frame 221. A discharge shaft 226 is rotatably engaged at the top center of the second support frame 221. Discharge plates 227 are uniformly fixedly connected to the outer surface of the discharge shaft 226. A material feeding shaft 222 is rotatably engaged at the top of the second support frame 221 on one side of the discharge shaft 226. A drive spindle 228 is rotatably engaged at the top of the second support frame 221 on the other side of the discharge shaft 226. The discharge shaft 226 and the drive spindle... A second transmission sprocket 225 is fixedly installed at both ends of the 228. A first transmission sprocket 223 is fixedly installed at both ends of the feeding shaft 222 and the unloading shaft 226. A first transmission chain 224 is meshed with the outer surfaces of the first transmission sprocket 223 and the second transmission sprocket 225. A second transmission chain 229 is meshed with the outer surface of one end of the unloading shaft 226. A drive motor 230 is fixedly installed on the top of the second support frame 221 and at one end of the drive shaft 228.

[0034] Through the above technical solution, the drive spindle 228, the unloading spindle 226 and the feeding spindle 222 can rotate synchronously. At the same time, the drive spindle 228 can control the conveyor belt 11 to rotate, the unloading feeder 227 can unload the falling products at a uniform speed, and the feeding spindle 222 can flip the falling products to ensure that the products are in an upward position, and facilitate the laser head 14 to mark the products.

[0035] The bottom of the product feeding hopper 212 is welded with support frames 211 at the four corners. The bottom of the product feeding hopper 212 is provided with a discharge port 215. A winding reel 216 is fixedly installed at the end of the transmission shaft 2113 away from the second transmission gear 2112. A connecting rope 217 is fixedly connected to the outer surface of the winding reel 216. A counterweight block 218 is fixedly connected to the bottom end of the connecting rope 217.

[0036] The laser marking mechanism 1 has a first support frame 12 fixedly installed inside. A conveyor belt 11 is rotatably installed on the top of the first support frame 12. A collection box 17 is provided at one end of the first support frame 12. A pouring plate 16 is provided on the top of the first support frame 12 and at one end of the conveyor belt 11. A protrusion 13 is provided inside the end of the conveyor belt 11 away from the pouring plate 16. A display 15 is fixedly installed on the side of the first support frame 12. A laser head 14 is movably installed on the side of the first support frame 12 and at the edge of the display 15.

[0037] The side of the counterweight 218 is slidably engaged with one end face of the second support frame 221. The transmission shafts 2113 are rotatably connected to each other through the first transmission gear 219. The gear shaft 2110 is meshed with the second transmission gear 2112 through the half gear 2111.

[0038] Through the above technical solution, the side of the counterweight 218 can be slidably engaged with one end face of the second support frame 221, thereby ensuring the stable lifting and lowering of the counterweight 218. Moreover, the transmission shafts 2113 are rotatably connected to each other through the first transmission gear 219, thereby enabling the two sets of flipping plates 214 to flip synchronously in opposite directions. The gear shaft 2110 is meshed with the second transmission gear 2112 through the half gear 2111, which enables the half gear 2111 to intermittently drive the second transmission gear 2112 to rotate.

[0039] The feeding shaft 226 is rotatably connected to the gear shaft 2110 via the second transmission chain 229. The feeding shaft 226 is rotatably connected to the drive shaft 228 via the first transmission chain 224. The drive motor 230 is rotatably connected to one end of the conveyor belt 11 via the drive shaft 228.

[0040] Through the above technical solution, the feeding shaft 226 can be rotatably connected to the gear shaft 2110 via the second transmission chain 229, so that when the drive motor 230 rotates, it can synchronously drive the tilting plate 214 to rotate in a small-amplitude cycle. The feeding shaft 226 is rotatably connected to the drive main shaft 228 via the first transmission chain 224, so that the drive motor 230 can control the feeding plate 227 to rotate at the bottom of the product feeding hopper 212, thereby continuously conveying the product. The drive motor 230 is rotatably connected to one end of the conveyor belt 11 via the drive main shaft 228, so that the drive motor 230 can synchronously control the rotation of the conveyor belt 11 when it is running.

[0041] The drive spindle 228 is rotatably connected to both ends of the feeding shaft 222 via the first transmission chain 224. The feeding shaft 222 is uniformly provided with L-shaped baffles on its outer surface. The feeding shaft 226 is rotatably engaged with the center of the discharge port 215 via the feeding baffle 227 in the middle.

[0042] Through the above technical solution, the drive spindle 228 can be rotatably connected to both ends of the feeding shaft 222 via the first transmission chain 224, thereby controlling the feeding shaft 222 to rotate synchronously. Since the feeding shaft 222 is uniformly provided with L-shaped baffles on its outer surface, when the feeding shaft 222 rotates, the L-shaped baffles will flip and adjust the product, thereby ensuring that the product is in an upward position. The unloading shaft 226 is rotatably engaged with the center of the discharge port 215 via the unloading baffle 227 in the middle, thereby limiting the rotation of the unloading shaft 226.

[0043] The limiting inclined plate 213 is inclined inside the product feeding hopper 212, the discharge port 215 is aligned with one end of the upper surface of the conveyor belt 11, the weight of the counterweight 218 is twice the weight of the product inside the top of the product feeding hopper 212, and one end of the drive spindle 228 is fixedly connected to one end of the drive motor 230.

[0044] Through the above technical solution, the limiting inclined plate 213 is inclined inside the product feeding hopper 212, which enables the product on the upper surface to slide down automatically. The discharge port 215 is aligned with one end of the upper surface of the conveyor belt 11, which can ensure that the product falls onto the upper surface of the conveyor belt 11. The weight of the counterweight 218 is twice the weight of the product inside the top of the product feeding hopper 212, which can ensure that the tilting plate 214 provides stable support for the product inside the product feeding hopper 212. One end of the drive main shaft 228 is fixedly connected to one end of the drive motor 230, which can control the rotation of the conveyor belt 11.

[0045] The working principle of this invention is as follows: First, a large number of small-volume products are added to the top of the product feeding hopper 212. Simultaneously, the drive motor 230 is started and rotates. The drive motor 230 drives the conveyor belt 11 to rotate synchronously through the drive shaft 228 at one end. The rotation of the drive shaft 228 drives the unloading shaft 226 to rotate synchronously through the first transmission chains 224 at both ends. The rotation of the unloading shaft 226 drives the feeding shaft 222 to rotate synchronously through the first transmission chains 224 at both ends. When the unloading shaft 226 rotates, it drives the gear shaft 2110 to rotate through the second transmission chain 229 at one end. When the gear shaft 2110 rotates, it drives the second transmission gear 2112 to rotate synchronously through the half gear 2111. Therefore, when the half gear 2111 rotates one revolution, it will drive the second transmission gear 2112 to deflect slightly. Moreover, the transmission shaft 2113 will wind up the connecting rope 217 through the winding reel 216 at one end. When the connecting rope is wound up 217, it will cause the counterweight 218 to rise. At the same time, the second transmission gear 2112 will drive the tilting plate 214 to deflect synchronously by a small amount through the transmission shaft 2113, so that the two sets of tilting plates 214 will deflect downward synchronously. Meanwhile, the products inside the product feeding hopper 212 will fall to the bottom of the product feeding hopper 212 under the action of gravity. The falling products will fall between the feeding plates 227, and as the feeding shaft 226 rotates, the feeding plates 227 will rotate and transport the products downward, and the products will fall through the discharge port 215 onto the upper surface of the conveyor belt 11. The rotation of the conveyor belt 11 will transport the products on the upper surface. When the products pass the upper surface of the protrusion 13, the rotating feeding shaft 222 will flip the bottom-up products through the L-shaped plates on the outer surface, so as to ensure that all products are placed on the upper surface of the conveyor belt 11 with the top facing up, avoiding marking processing on the bottom surface of the products.As the conveyor belt 11 transports the product to the bottom of the laser head 14, the laser head 14 marks the top outer surface of the product. Finally, the product is conveyed by the conveyor belt 11 through the guide plate 16 and into the collection box 17 for collection. Simultaneously, as the half gear 2111 separates from the second transmission gear 2112, the counterweight 218, under the influence of gravity, pulls the transmission shaft 2113 to rotate and reset via the connecting rope 217. This causes the transmission shaft 2113 to cause the outer surface tilting plate 214 to contact the bottom side of the limiting inclined plate 213, preventing the product from falling further. As the drive motor 230 rotates, the half gear 2111 intermittently drives the second transmission gear 2112 to deflect slightly. Therefore, the tilting plate 214 repeatedly deflects inside the product feeding hopper 212, causing the product to be intermittently discharged downwards. This simultaneously achieves cyclical feeding of products to the bottom of the laser head 14 and prevents products from accumulating at the bottom of the product feeding hopper 212, thus ensuring smooth product discharge. This invention, by setting a feeding mechanism 2 at the top of one end of the laser marking mechanism 1, enables automatic cyclic feeding of products by the vision three-axis laser marking machine, achieving automatic continuous marking processing.

[0046] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
