Description

Technical Field

[0001] The invention relates to the technical field of laser processing, in particular to a laser edge banding machine with laser marking equipment. Background Art

[0002] Laser edge banding machine is a high-end equipment used in the field of furniture manufacturing. It is mainly used for edge banding of panels to achieve seamless connection and improve the appearance quality of products. Its core technology is to melt the functional layer of the edge banding tape through a laser beam so that it is tightly combined with the panel, thereby achieving efficient, accurate and environmentally friendly edge banding effect. Using a high-energy rectangular laser spot, the functional layer of the edge banding tape is quickly melted, and the edge banding tape is tightly attached to the panel through a pressing wheel. This process does not require traditional glue, reduces material loss and secondary operations, and improves edge banding efficiency and quality. At the same time, the laser edge banding machine is generally equipped with a laser marking device to display the information of the panel.

[0003] The laser edge banding machine in the prior art needs to press the edge banding strip after edge banding to ensure tight adhesion, but this process will also cause the melted adhesive layer polymer to be easily squeezed outward, thereby causing polymer residues on the edge, which will need to be cleaned again later. The operation steps are cumbersome, and there is a certain probability that the edge banding strip will be offset during the extrusion process, and slight offsets cannot be detected in time. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a laser edge banding machine with a laser marking device to solve the problems raised in the above-mentioned background technology. The present invention can connect the edge banding strip that has been cut in advance with the edge of the moved plate at a smaller bending angle, thereby improving the accuracy of the connection and avoiding the problem that the edge banding strip is in a large-angle bending state for a long time, resulting in a decrease in the firmness of the subsequent adhesion. In conjunction with the trace removal monitoring mechanism, the extruded polymer residue can be cleaned and the offset problem caused after the edge banding can be monitored and detected.

[0005] To achieve the above object, the present invention is realized by the following technical solutions: A laser edge-sealing machine with a laser marking device, including a laser edge-sealing machine body.

Cut edge-sealing strips are stacked inside the feeding mechanism, and the plates to be edge-sealed are sequentially moved over the tops of the front-end conveying mechanism and the rear-end conveying mechanism.

[0006] Further, both the front-end conveying mechanism and the rear-end conveying mechanism include a conveyor belt, a motor, and a surrounding plate. The surrounding plate is installed on both sides of the conveyor belt. The motor is screwed to one end of the surrounding plate. Positioning columns are inserted into the inner wall of the surrounding plate. The motor is used to drive the conveyor belt to rotate in a cycle.

[0007] Further, the positioning component includes a first bracket, a pneumatic channel, and a limiting stop rod. The bottom of the first bracket is welded to the surrounding plate of the rear-end conveying mechanism. The pneumatic channel is screwed to the outside of the first bracket. One end of the pneumatic channel is connected to the limiting stop rod, and an air supply pipe is connected to the end of the pneumatic channel.

[0008] Further, the number of side baffles is two, and there is a gap between the two side baffles. The feeding mechanism includes a first electric lifting rod, a second electric lifting rod, a support rod, and a pressing rod. A base is welded to the outside of the side baffle.

[0009] Further, the bottoms of the first electric lifting rod and the second electric lifting rod are both screwed to the surface of the base. End plates are screwed to the tops of the first electric lifting rod and the second electric lifting rod. A strip-shaped hole is opened on the surface of the side baffle. The support rod and the pressing rod both pass through the inside of the strip-shaped hole, and both ends of the support rod and the pressing rod are welded to the side of the end plate.

[0010] Further, the support rod is used to support the bottom of the edge-sealing strip, and the pressing rod is used to press the top of the edge-sealing strip. The number of support rods is two, and the two support rods are always on the same horizontal plane. The number of pressing rods is one.

[0011] Furthermore, a second bracket is provided on the side of the trace removal monitoring mechanism, the bottom of the second bracket is welded to the enclosure, a lifting groove is provided on the surface of the second bracket, the glue removal mechanism includes a glue removal bin and a shovel plate, the top of the glue removal bin is integrally formed with a back plate, a spring rod is inserted on the surface of the back plate, and the end of the spring rod is connected to the shovel plate.

[0012] Furthermore, the bottom of the shovel plate is pressed on the top of the glue removal bin, and conductive wires are inserted into the inside of the shovel plate and the top of the glue removal bin. The top of the glue removal bin is in an open state, and a lifting block is integrally formed at the rear end of the back plate.

[0015] Beneficial effects of the present invention:

[0016] 1. The laser edge banding machine with laser marking equipment can dock the pre-cut edge banding strips with the edge of the moved plate at a smaller bending angle. The plate to be edge-banded at the bottom is moved and controlled by the positioning component at the rear end to ensure that the top edge banding strip can be accurately docked with the end of the plate, which improves the accuracy of docking and avoids the problem of reduced firmness of later bonding due to the edge banding strip being in a large-angle bending state for a long time.

[0017] 2. The laser edge banding machine with laser marking equipment can clean the extruded polymer residues in conjunction with the trace removal monitoring mechanism. Even if a large extrusion force is provided, causing the polymer in some bonding areas to overflow outward, the glue removal mechanism can scrape off the overflowed residues as the plate moves, thereby achieving the purpose of cleaning.

[0018] 3. The laser edge banding machine with laser marking equipment monitors and detects the offset problem after edge banding. When the processed edge banding strip is offset laterally, the scraper part in the glue removal mechanism will shake, which will cause the internal circuit signal to be disconnected, thereby monitoring the offset of the current edge banding strip.

Detailed implementation manners

[0027] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0028] Please refer to Figures 1 to 7, the present invention provides the following technical solutions: A laser edge sealer with a laser marking device, comprising a laser edge sealer body. The laser edge sealer body includes a front-end conveying mechanism 1, a rear-end conveying mechanism 2, a feeding mechanism 4, and a scar removal monitoring mechanism 5. The inner sides of the front-end conveying mechanism 1 and the rear-end conveying mechanism 2 are both sleeved with conveyor belts 7, and the front-end conveying mechanism 1 and the rear-end conveying mechanism 2 are welded and fixed. A side baffle 3 is welded to the top of the front-end conveying mechanism 1. Extension plates 33 are screwed on both sides of the side baffle 3. A laser 34 is screwed to the bottom of one of the extension plates 33, and a marking module 35 is installed at the bottom of the other extension plate 33. The feeding mechanism 4 is inserted through the surface of the side baffle 3. A scar removal monitoring mechanism 5 and a positioning component 6 are built on the surface of the rear-end conveying mechanism 2. The scar removal monitoring mechanism 5 includes a pressing mechanism 17 and a degumming mechanism 18. Cut edge strips are stacked inside the feeding mechanism 4. The plates to be edge-sealed are sequentially moved over the tops of the front-end conveying mechanism 1 and the rear-end conveying mechanism 2. This laser edge sealer is used for edge-sealing plates and can simultaneously perform marking processing on the edge-sealed plates.

[0029] When the present invention is in use, the plates to be edge-sealed are directly placed on the front-end conveying mechanism 1 in a vertical posture, and the plates are conveyed by the conveyor belt 7 in the conveying mechanism until they move inside the side baffle 3. Edge strip materials that have been cut are stacked in the side baffle 3, and the length and width of each edge strip are the same as the size specifications of the top side of the plate. When the plate moves inside the side baffle 3 and aligns its end with the end of the stacked edge strips, the feeding mechanism 4 can be operated to apply a downward pressure to the top of the rear end of the stacked edge strips. With this pressure, the end of the bottommost edge strip is fitted to the edge of the plate. At the same time, the bottom functional layer of the edge strip is irradiated and melted by the laser 34 to form an adhesive liquid polymer. Along with the pressing of the feeding mechanism 4, contact adhesion is generated between the adhesive material and the edge of the plate. Finally, the pasted plate and the edge strip move backward with the front-end conveying mechanism 1 until they move into the scar removal monitoring mechanism 5, where the edge strip is pressed, the edge of the edge strip is scraped and cleaned, and whether the edge strip has shifted is monitored.

[0030] In this embodiment, the front conveying mechanism 1 and the rear conveying mechanism 2 both include a conveyor belt 7, a motor 10 and a guard plate 8. The guard plate 8 is installed on both sides of the conveyor belt 7. The motor 10 is screwed to one end of the guard plate 8. A positioning column 9 is inserted into the inner wall of the guard plate 8. The motor 10 is used to drive the conveyor belt 7 to rotate in a cycle. The positioning assembly 6 includes a first bracket 11, a pneumatic channel 12 and a limiting stop rod 13. The bottom of the first bracket 11 is welded to the guard plate 8 of the rear conveying mechanism 2. The pneumatic channel 12 is screwed to the outside of the first bracket 11. One end of the pneumatic channel 12 is connected to the limiting stop rod 13. The end of the pneumatic channel 12 is connected to an air supply pipe 14.

[0031] Specifically, the front conveying mechanism 1 and the rear conveying mechanism 2 cooperate with each other to convey the board. The position of the board is restricted by the positioning column 9 inside the guard plate 8 to ensure that the board can move along the middle area of the conveyor belt 7. While the motor 10 controls the rotation of the conveyor belt 7, the pneumatic channel 12 is controlled to inflate or deflate through an external control system, so as to adjust the extended state of the limiting stop rod 13, and then block the board during the movement. When the board after edge banding is blocked, the subsequent boards can be blocked synchronously to make them stationary. Therefore, by means of this stationary state, the edge banding strip can be butt - pressed against the bottom board, reducing the offset probability caused by the initial butt joint during the movement.

[0032] In this embodiment, the number of the side baffles 3 is two, and there is a gap between the two side baffles 3. The feeding mechanism 4 includes a first electric lifting rod 37, a second electric lifting rod 38, a supporting rod 40 and a pressing rod 41. A base 36 is welded to the outside of the side baffle 3. The bottoms of the first electric lifting rod 37 and the second electric lifting rod 38 are both screwed to the surface of the base 36. The tops of the first electric lifting rod 37 and the second electric lifting rod 38 are both screwed to an end plate 39. A strip - shaped hole 32 is formed on the surface of the side baffle 3. The supporting rod 40 and the pressing rod 41 both pass through the inside of the strip - shaped hole 32, and both ends of the supporting rod 40 and the pressing rod 41 are welded to the side of the end plate 39. The supporting rod 40 is used to support the bottom of the edge banding strip, and the pressing rod 41 is used to press the top of the edge banding strip. The number of the supporting rods 40 is two, and the two supporting rods 40 are always on the same horizontal plane. The number of the pressing rods 41 is one. The pre - cut edge banding strip can be butted against the edge of the moved board at a small bending angle. The board to be edge - banded at the bottom is controlled to move through the positioning assembly 6 at the rear, ensuring that the edge banding strip at the top can be accurately butted against the end of the board, improving the accuracy of the butt joint and avoiding the problem that the edge banding strip is in a large - angle bending state for a long time, resulting in a decrease in the later sticking firmness.

[0033] Specifically, the first electric lifting rod 37 drives the upper end plate 39 and the supporting rod 40 to lift, so that the edge banding strips stacked inside the side baffle 3 can be lifted synchronously. The second electric lifting rod controls the end plate 39 and the butt - pressed rod 41 to apply a downward pressure, so that a downward extrusion pressure can be applied to the rear - end area of the stacked edge banding strips. With the help of this extrusion pressure, it can be ensured that the end of the lowermost edge banding strip first contacts and fits with the rear end of the moving sheet. At the same time, the bottom of the edge banding strip can be in an inclined state with a small included angle, so that the laser beam generated by the laser 34 can be irradiated onto the bottom surface of the edge banding strip that is about to contact the sheet, for melting the functional layer on the bottom surface to facilitate subsequent bonding.

[0034] In this embodiment, a second bracket 15 is arranged on the side of the trace - removing monitoring mechanism 5. The bottom of the second bracket 15 is welded to the enclosing plate 8. A lifting groove 16 is formed on the surface of the second bracket 15. The degumming mechanism 18 includes a degumming bin 19 and a scraping plate 21. A back plate 20 is integrally formed at the top of the degumming bin 19. A spring rod 22 is inserted on the surface of the back plate 20. The end of the spring rod 22 is connected to the scraping plate 21. The bottom of the scraping plate 21 presses on the top of the degumming bin 19, and conductive wires 23 are inserted into both the inside of the scraping plate 21 and the top of the degumming bin 19. The top of the degumming bin 19 is in an open state. A lifting block 24 is integrally formed at the rear end of the back plate 20. A vertical plate 25 is welded to the rear end of the lifting block 24. A top plate 26 is welded to the top of the vertical plate 25. A first threaded rod 27 is inserted in the middle of the top plate 26. The bottom end of the first threaded rod 27 is movably connected to the surface of the second bracket 15 through a bearing. The pressing mechanism 17 includes a pressing wheel 28 and a linkage plate 29. The bottom of the linkage plate 29 is inserted at both ends of the pressing wheel 28. A guiding rod 31 is welded to the top of the linkage plate 29. A second threaded rod 30 is inserted through the middle of the second bracket 15. The bottom end of the second threaded rod 30 is movably connected to the surface of the linkage plate 29 through a bearing. The guiding rod 31 passes through the top of the second bracket 15. It can cooperate with the trace - removing monitoring mechanism 5 to clean the extruded polymer residue. Even if a large extrusion pressure is provided and part of the polymer in the bonding area overflows outward, as the sheet moves, the degumming mechanism 18 can scrape off the overflowed residue part to achieve the purpose of cleaning.

[0035] Specifically, after the sheet with the edge banding strip pasted on it moves to the bottom of the pressing wheel 28, the pressing wheel 28 can apply a downward pressure to the top of the edge banding strip to improve the firmness after the edge banding strip is pasted. And the pressing height of the pressing wheel 28 can be directly adjusted by rotating the second threaded rod 30 at the top. Cooperating with the guiding rod 31, the pressing wheel 28 can always move vertically up and down.

[0036] The offset problem after edge banding is monitored and investigated. When the processed edge banding strip is laterally offset, the scraper plate 21 in the glue removal mechanism 18 will shake, which will cause the internal circuit signal to be disconnected, thereby monitoring the offset of the current edge banding strip. Specifically, the connection position between the bottom of the shovel plate 21 and the degumming bin 19 is consistent with the height at which the edge banding is bonded to the plate. Therefore, after the edge banding is bonded to the plate, when it moves from the inner side of the degumming mechanism 18, the shovel plate 21 can provide a pressing and scraping effect on the connection position between the edge banding and the plate. After part of the bonded polymer overflows toward the outside due to the pressure applied by the pressing mechanism 17, it can be scraped off by the shovel plate 21 and collected in the degumming bin 19 to the inside. When the bonding position of the edge banding is offset, the edge banding protrudes toward one side, which applies a thrust to the shovel plate 21, thereby compressing the spring rod 22, and the conductive wire 23 on the shovel plate 21 is offset from the conductive wire 23 on the degumming bin 19. Therefore, the monitoring circuit generates a disconnection signal, and the current offset problem of the edge banding is judged by the signal. The entire degumming mechanism 18 can also control the vertical plate 25 to rise and fall by rotating the first threaded rod 27 at the top, so as to be applied to processing plates of different sizes.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
