Description

Technical Field

[0001] This invention relates to the field of laser engraving technology, and in particular to a laser engraving machine. Background Technology

[0002] In recent years, laser processing technology has been increasingly applied to the field of material surface treatment due to its advantages such as non-contact processing, high precision, and strong controllability. Laser texturing machines, as a new type of surface texture processing equipment, utilize high-energy laser beams to locally ablate or melt the surface of molds or workpieces, thereby forming the desired texture patterns. This technology not only achieves high-precision replication of complex patterns but also enables flexible pattern design and rapid switching through digital control, significantly improving processing efficiency and repeatability. Currently, laser texturing machines are primarily semi-automatic, requiring continuous manual loading and unloading, which can easily lead to fatigue under prolonged manual labor, thus reducing processing efficiency.

[0048] The unloading device 16 includes a third conveying component 161 and an unloading component 162 located at one end of the third conveying component 161. The moving direction of the third conveying component 161 is the same as the moving direction of the second conveying component 141. The unloading component 162 and the loading component 122 are both located on the same side of the machine base 11.

[0049] The flipping device 17 includes a first flipping component installed on one side of the first conveying component 121 and a second flipping component installed on one side of the third conveying component 161;

[0050] The moving device 15 includes a first fixed frame 151 that spans the first conveying assembly 121, the flipping device 17, the second conveying assembly 141, and the third conveying assembly 161 in sequence, and a first suction assembly 152 and a second suction assembly 153 that are respectively mounted on the first fixed frame 151 and movable along the length of the first fixed frame 151. The first suction assembly 152 is used to move the products on the first conveying assembly 121 to the first flipping assembly and the positioning assembly 142 respectively, and the second suction assembly 153 is used to move the products on the positioning assembly 142 to the second flipping assembly and the third conveying assembly 161 respectively.

[0051] The etching device 13 includes a second fixed frame 131 located on one side of the first fixed frame 151 and a laser etching machine 133 mounted on the second fixed frame 131. The positioning device 14 moves on the second conveying assembly 141 to move the positioning assembly 142 away from or closer to the laser etching machine 133.

[0052] The machine base 11 is used to install a feeding device 12, a flipping device 17, a moving device 15, a positioning device 14, a texturing device 13, and a discharging device 16. The feeding device 12 is used for automatic feeding, conveying the tray to one side of the first flipping component. The first suction component 152 picks up the product on the tray and places it on the first flipping component. The first flipping component flips the product to turn it over. The first suction component 152 picks up the flipped product and places it on the positioning component 142. The positioning component 142 positions the product. After the product is positioned, the positioning component 142 moves on the second conveying component 141 towards the texturing device 13. When the product is below the laser etching machine 133, the laser etching machine 133 performs laser processing on the surface of the product. After the product processing is completed, the positioning component 14... 2. The product moves in the initial direction on the second conveying component 141. Further, after the positioning component 142 is in the initial position, the positioning component 142 releases the positioning of the product. The first suction component 152 moves the product on the positioning component 142 to the second flipping component. The second flipping component flips the product again to the position when the product was fed. The second suction component 153 places the product on the second flipping component onto the fixture on the third conveying component 161. The third conveying component 161 moves the fixture to the unloading component 162, thereby completing the automatic feeding, flipping, positioning, engraving, flipping again, and unloading process of the product. This allows the laser engraving equipment to process products continuously, reducing manual operation while effectively improving processing output and efficiency.

[0053] Please refer to Figure 3 and Figure 4 , Figure 3 This is a perspective view of the positioning device of the laser-driven flower-carving machine of the present invention. Figure 4 for Figure 3The enlarged view of part A shows that the positioning assembly 142 includes a fixed base 1411 movable on the second conveying assembly 141, a third fixed frame 1417 mounted on one side of the fixed base 1411, a first fixture 1418 mounted on the third fixed frame 1417 at both ends and rotatable on the third fixed frame 1417, a first motor 1419 mounted on one end of the third fixed frame 1417 for driving the first fixture 1418 to rotate, a first fixed plate 1414 mounted on one side of the third fixed frame 1417, a first cylinder 1415 mounted on the first fixed plate 1414, and a limiting member 1416 mounted on the first cylinder 1415. The first motor 1419 drives the first fixture 1418 to rotate towards the limiting member 1416, and the first cylinder 1415 drives the limiting member 1416 to conform to the product on the first fixture 1418. The fixed base 1411 is used to move on the second conveyor assembly. The third fixed frame 1417 is used to install the first fixture 1418 and the first motor 1419. The first motor 1419 is used to drive the first fixture 1418 to rotate. The first fixed plate 1414 is used to install the first cylinder 1415. The first cylinder 1415 is used to drive the limiting member 1416 to move towards the first fixture 1418. The first motor 1419 drives the first fixture 1418 to rotate to adjust the angle of the product on the first fixture 1418, so that the angle of the product can be adjusted when engraving products of different specifications. The first cylinder 1415 drives the limiting member 1416 to move towards the first fixture 1418, so that the limiting member 1416 fits the product, thereby firmly fixing the product on the first fixture 1418 and preventing the product from shifting position when moving on the second conveyor assembly 141.

[0054] The first cylinder 1415 is inclined. The limiting member 1416 includes a second fixed plate connected to the first cylinder 1415 and limiting blocks symmetrically mounted on the second fixed plate. The first cylinder 1415 drives the second fixed plate to move tilted so that the symmetrical limiting blocks fit against the product on the first fixture 1418. Multiple sets of limiting members 1416 are provided. The first fixed plate 1414 is used to connect to the first cylinder 1415. The first cylinder 1415 is used to drive the second fixed plate to move towards the third fixed frame 1417 to reduce the distance between the limiting block and the third fixture 176. The inclined first cylinder 1415 can reduce the volume of the positioning component 142 and prevent the positioning component 142 from being too wide. At the same time, the symmetrically arranged limiting blocks can limit two products at the same time. Multiple sets of limiting members 1416 are provided, and multiple sets of limiting members 1416 further limit multiple products. During processing, multiple products can be processed continuously to speed up the efficiency of product processing.

[0055] The fixed base 1411 is also provided with a second cylinder 1412, a third fixed plate connected to the second cylinder 1412, and a third cylinder 1413 connected to the third fixed plate. The first fixed plate 1414 is connected to the third cylinder 1413, and the third fixed bracket 1417 is mounted on the third fixed plate. The second cylinder 1412 is used to drive the third fixed plate to move to adjust the position of the first fixture 1418, and the third cylinder 1413 is used to drive the first fixed plate 1414 to move so that the limiting member 1416 moves away from or closer to the first fixture 1418. The second cylinder 1412 is used to drive the third fixing plate to move. The third fixing plate is used to mount the third cylinder 1413 and the third fixing bracket 1417. The third fixing plate is used to drive the third cylinder 1413 and the third fixing bracket 1417 to move, so as to adjust the position of the first fixture 1418, thereby facilitating the etching of the set pattern or graphic on the product. The third mounting plate is mounted on the second cylinder 1412. The second cylinder 1412 is used to drive the limiting member 1416 to move towards the third mounting bracket, so as to further shorten the distance between the limiting member 1416 and the fixture.

[0056] Please refer to Figure 11 , Figure 11 for Figure 8 A partial enlarged view of part B shows that both the first and second flipping assemblies include a first mounting bracket 171, a rotary cylinder 172 fixed to one end of the inner side of the first mounting bracket 171, a second fixture 173 with one end connected to the rotary cylinder 172 and the other end rotatable on the first mounting bracket 171, a fourth cylinder 174 mounted below the first mounting bracket 171, an L-shaped connecting plate 175 mounted above the fourth cylinder 174, and a third fixture 176 mounted on the connecting plate 175. The rotary cylinder 172 drives the second fixture 173 to flip, transferring the product from the second fixture 173 to the third fixture 176. The fourth cylinder 174 drives the third fixture 176 away from or towards the second fixture 173. Mounting bracket 171 is used to mount rotary cylinder 172 and second fixture 173. Rotary cylinder 172 is used to drive second fixture 173 to rotate. Fourth cylinder 174 is used to mount connecting plate 175. Connecting plate 175 is used to mount third fixture 176. L-shaped connecting plate 175 is used to avoid second fixture 173. When rotary cylinder 172 drives second fixture 173 to rotate, the product on the flipped second fixture 173 can fall stably onto third fixture 176. After third fixture 176 receives the product, fourth cylinder 174 drives connecting plate 175 to rise. Connecting plate 175 drives third fixture 176 to rise, so as to reduce the distance between first suction component 152 or second suction component 153 and the product on third fixture 176.

[0057] Please refer to Figure 9 , Figure 9This is a perspective view of the feeding assembly of the laser-engraved flower machine of the present invention. The feeding assembly 122 includes a second mounting frame 1221 fixed on the first conveying assembly 121 for limiting the material tray, a first lifting member 1222 located within the second mounting frame 1221, a placement plate 1223 mounted on the first lifting member 1222 for placing the material tray, a platform 1224 located at the top of the second mounting frame 1221, and clamping members 1225 symmetrically arranged on both sides of the platform 1224 for clamping the material tray. The first lifting member 1222 drives the placement plate 1223 to rise and fall, thereby driving the material tray to rise and fall. The clamping members 1225 are used to clamp empty material trays. The second mounting frame 1221 is used to mount the first lifting member 1222 and the platform 1224. The first lifting member 1222 is used to mount the placement plate 1223. The clamping members 1225 are used to clamp empty material trays. The placement plate 1223 is used to place the material tray filled with products. When a material tray filled with products is placed on the placement plate 1224... When the tray is placed on plate 1223, the first lifting component 1222 is used to move the placement plate 1223, so as to facilitate the placement of the tray filled with products on the first conveying component 121. After the products on the tray on the first conveying component 121 are picked up by the first suction component 152, the first conveying component 121 moves the tray above the placement plate 1223. The first lifting component rises, so that the tray filled with products on the placement plate 1223 pushes the empty tray to move. The tray filled with products pushes the empty tray to move, so that the empty tray passes through the clamping component 1225. The clamping component 1225 clamps the empty tray. The first lifting component descends again, so that the tray filled with products and the empty tray are separated. At the same time, it is also convenient for the first lifting component to place the tray filled with products on the first conveying component 121 to form a cycle, reducing the number of times the empty tray is manually moved. At the same time, the trays filled with products and the empty trays are stacked together, thereby reducing the size of the laser engraving machine.

[0058] Please refer to Figure 10 , Figure 10This is a perspective view of the first conveying component of the laser-engraved flower machine of the present invention. The first conveying component 121 includes symmetrically arranged guide rails 1211, a clamping component movable on the guide rails 1211 for clamping a material tray, and a moving member located inside the guide rails 1211 for driving the clamping component to move on the guide rails 1211. The clamping component includes a fixed frame 1217 with its two sides respectively connected to the guide rails 1211, a fifth cylinder 1212 fixed to one end of the fixed frame 1217, and a third cylinder 1212. The fifth cylinder 1212 is connected to a crossbar 1213, a slide plate 1214 connected to both sides of a fixed frame 1217 and to both ends of the crossbar 1213, and a fixing post fixed to the fixed frame 1217 and passing through the slide plate 1214. The slide plate 1214 is provided with an inclined strip hole 1216, and the inner side of the slide plate 1214 is provided with multiple L-shaped limit hooks 1215 for locking the material tray. The fixing post is connected to the strip hole 1216. The fifth cylinder 1212 drives the slide plate 1212. The crossbar 1213 moves to move the slide plate 1214. When the slide plate 1214 moves according to the movement trajectory of the slot 1216, the limiting hook 1215 clamps or moves away from the tray. The moving component is used to drive the clamping assembly to move on the guide rail 1211, thereby facilitating the clamping assembly to move the tray full of products below the moving device 15 and to move the empty tray into the second mounting bracket 1221. When the clamping assembly needs to clamp the tray, the fifth cylinder 1212 drives the crossbar 1213 to move the tray. 213 moves, and the crossbar 1213 drives the slide plates 1214 at both ends to slide on the fixed frame 1217. When the slide plates 1214 move, the sliding track of the slide plates 1214 is limited by the strip hole 1216, so that the slide plates 1214 at both ends of the crossbar 1213 move relative to each other. When the slide plates 1214 move, they drive the limiting hook 1215 to move, so that the limiting hook 1215 can clamp the material box full of products. Conversely, the limiting hook 1215 separates the empty material tray.

[0059] In this embodiment, the principle of feeding empty trays by the feeding device 16 is the same as that of feeding trays filled with products by the feeding device 12, and will not be repeated. The principle of feeding trays filled with products by the feeding device 16 is the same as that of feeding trays filled with empty products by the feeding device 12, and will not be repeated.

[0060] The positioning device 14 is provided in two sets, which are arranged side by side and located between the first flipping component and the second flipping component, respectively. The two sets of positioning devices 14 are used to stagger the positioning of the product. When the first set of positioning devices 14 has positioned the product and moved it to the laser etching machine 133 for engraving, the first suction component 152 can place the product on the second set of positioning devices 14 for positioning. The first set of positioning devices 14 and the second set of positioning devices 14 engrave alternately, which further increases and speeds up the product processing efficiency.

[0061] The first fixed frame 151 is also provided with a connecting frame and a suction nozzle 134 connected to the connecting frame on the side near the laser etching machine 133. The suction nozzle 134 is inclined and tilted towards the laser etching machine 133. The suction nozzle 134 is used to draw out the smoke from the products processed by the laser etching machine 133, thereby preventing the smoke from drifting into the machine 11 and effectively preventing the operator from inhaling the smoke, so as to effectively protect the safety of the operator.

[0062] The second fixed frame 131 is also provided with a second lifting component 132. The laser etching machine 133 is installed on the second lifting component 132. The second lifting component 132 is used to adjust the height of the laser etching machine 133. The second lifting component 132 is used to raise or lower the height of the laser etching machine 133 so that the laser etching machine 133 can engrave products of different specifications. The laser etching machine can process products of different specifications more conveniently.

[0063] Working principle:

[0064] When engraving the product, firstly, the tray filled with the product is placed on the placement plate 1223 within the second mounting frame 1221. The first lifting component 1222 drives the placement plate 1223 to rise, causing the tray filled with the product at the top of the placement plate 1223 to pass through the fixing frame 1217. The fifth cylinder 1212 is activated, driving the crossbar 1213 to move. The crossbar 1213 pulls the slide plates 1214 at both ends of the crossbar 1213 to move. As the slide plates 1214 move, they follow the movement trajectory of the strip grooves on the slide plates 1214, causing the slide plates 1214 to move towards the tray. Simultaneously, the limiting hooks 1215 on the slide plates 1214 hold the bottom of the tray. At the same time, the first lifting component 1222... The lowering mechanism separates the tray at the top of the placement plate 1223 from the tray below the top of the placement plate 1223. The fixing frame 1217 moves along the guide rail 1211 toward the first flipping assembly. When the fixing frame 1217 is on one side of the first flipping assembly, the first suction assembly 152 moves on the first fixing frame 151, and the first suction assembly 152 sucks the product on the fixing frame 1217 onto the second fixture 173 on the first flipping assembly. The rotary cylinder 172 rotates, driving the second fixture 173 to flip. When the second fixture 173 flips, it flips the product on the second fixture 173 onto the third fixture 176. The fourth cylinder 174 drives the connecting plate 175 to rise. 5. The third fixture 176 is raised to shorten the distance between the third fixture 176 and the first suction component 152. After the product in the tray of the fixed frame 1217 is completely sucked up by the first suction component 152, the fixed frame 1217 moves towards the second mounting frame 1221 on the guide rail 1211. When the fixed frame 1217 is located in the second mounting frame 1221, the fifth cylinder 1212 pushes the crossbar 1213 to move. The crossbar 1213 drives the slide plate 1214 to move away from the fifth cylinder 1212. When the slide plate 1214 moves, it moves according to the movement trajectory of the strip hole 1216, causing the slide plate 1214 to move away from the tray. As the slide plate 1214 moves away, it also drives the limit... The position hook 1215 moves, causing the limit hook 1215 to contact the limit of the empty material tray. When the limit hook 1215 moves away from the empty material tray, the empty material tray falls onto the material tray at the top of the placement plate 1223. The first lifting component 1222 starts and drives the placement plate 1223 to rise. When the placement plate 1223 rises, it drives the material tray to rise. After the empty material tray passes through the platform 1224, the clamping component 1225 extends and penetrates the bottom of the hole material tray to limit the empty material tray on the platform 1224. After the empty material tray is limited on the platform 1224, the first lifting component 1222 descends again, causing the material tray with the product loaded on the top of the placement plate 1223 to move into the fixed frame 1217, so that the feeding component 122 feeds to form a cycle.

[0065] Furthermore, the first suction assembly 152 picks up the flipped product from the third fixture 176 and moves it to the first fixture 1418 on the positioning assembly 142. The third cylinder 1413 is activated, driving the first fixing plate 1414 to move, so that the limiting member 1416 moves closer to the first fixture 1418. When the third cylinder 1413 moves to the set position, the first motor 1419 drives the first fixture 1418 to rotate, adjusting the angle of the product to facilitate processing. The first cylinder 1415 is activated, driving the limiting block to move towards the product and fit against it, thereby positioning the product and preventing it from shaking or moving. After the limiting block limits the product, the fixing seat 1411 is positioned on the second conveying assembly 1412. The laser etching machine 133 moves in the direction of 1, causing the fixed seat 1411 to move below the texturing device 13. When the fixed seat 1411 is below the texturing device 13, the laser etching machine 133 engraves the surface of the product. At the same time as engraving, the second cylinder 1412 drives the third fixed plate to move. The second cylinder 1412 moves the third fixed plate to adjust the lateral direction of the second fixture 173, thereby facilitating engraving at different positions of the product. After the engraving is completed, the second cylinder 1412 drives the third fixed plate to reset. At the same time, the fixed seat 1411 moves on the second conveying assembly 141 to return the fixed seat 1411 to its initial position. Since there are two sets of positioning devices 14, the two sets of positioning devices 14 can move alternately to the bottom of the laser etching machine 133 to engrave the product, thus speeding up the engraving efficiency.

[0066] Furthermore, after the positioning device 14 moves the engraved product to the initial position, the second suction component 153 picks up the engraved product from the positioning device 14 and transfers it to the second flipping component. The second flipping component flips the product again to return it to the position when it was loaded. The second suction component 153 then picks up the product from the second flipping component and places it on the unloading device 16. Since the principle of the unloading device 16 for loading empty trays is the same as the principle of the loading device 12 for loading trays full of products, it will not be repeated here. The principle of unloading when the tray is full of products is the same as the principle of the loading device 12 for unloading empty trays, which will not be repeated here. Through the above method, automatic engraving of products is achieved, so that the laser engraving equipment can process products continuously, which can effectively improve processing output and processing efficiency while reducing manual operation.

[0067] In this preferred embodiment of the laser engraving machine, the material tray is conveyed to one side of the first flipping component by the first conveying component. The first suction component picks up the product and flips it over before moving it to the positioning component. After positioning the product, the positioning component moves it to the bottom of the engraving device for engraving via the second conveying component. The second suction component picks up the engraved product, flips it over, and moves it into the unloading device. This reduces manual operation and effectively improves processing output and efficiency.

[0068] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
