Description

Technical Field

[0001] This invention relates to the field of edge banding processing technology, and in particular to an automatic edge banding machine and its corresponding edge banding method. Background Technology

[0002] In furniture manufacturing, edge banding is a crucial step. Edge banding not only enhances the appearance of the furniture but also prevents the boards from warping or deforming during use or transportation. However, when edge banding boards with V-shaped sides, grooves must first be cut into the edge banding tape to allow for bending and better fit against the V-shaped sides, facilitating subsequent bonding. Existing cutting equipment for beveled edge banding tape requires readjusting the cutting blade position each time, resulting in low processing efficiency and poor compatibility. Summary of the Invention

[0003] In order to address the technical deficiencies mentioned in the background section, the present invention aims to provide a laser device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic edge banding machine includes a conveyor frame, a pressing device, a pressing and cutting device, a laser device, and a storage platform. It is characterized by further including a bevel grooving device, which is disposed at the discharge port of the storage platform. The bevel grooving device includes a reference base, a cutting blade, a cutting motor, and a blade adjustment assembly. The reference base is disposed on one side of the edge banding strip, and the side of the reference base in contact with the edge banding strip is configured as a reference surface with an arc structure. The cutting blade is disposed on the other side of the edge banding strip. The output shaft of the cutting motor is fixedly connected to the cutting blade, and the cutting blade is used to groove the edge banding strip. The blade adjustment assembly is used to adjust and fix the distance between the cutting blade and the reference surface to allow for the thickness of the edge banding strip between the side of the reference surface and the bottom of the groove on the grooved side of the edge banding strip.

[0006] By adopting the above technical solution, the edge banding tape is adhered to the reference surface, which is set as an arc surface structure, allowing for a tighter fit and improving grooving accuracy. The distance between the cutting blade and the reference surface is adjusted based on the remaining uncut thickness of the edge banding tape at the grooving position. Only the initial adjustment of the distance between the cutting blade and the reference surface is required, accommodating grooving operations with edge banding tapes of different thicknesses. This ensures that the remaining uncut thickness of edge banding tapes of different thicknesses remains consistent at the grooving position, improving equipment compatibility and grooving efficiency.

[0007] Furthermore, the bevel grooving device also includes a pressure strip support, a push rod, and a pressing block. The pressure strip support protrudes from the upper end of the reference base, the push rod is slidably mounted on the pressure strip support, and the pressing block is fixed below the push rod. The lower surface of the pressing block abuts against the upper side of the sealing strip, thereby ensuring that the sealing strip is stably attached to the reference surface during grooving. This ensures that the grooving position of the sealing strip is on the same horizontal line, preventing height differences, guaranteeing the sealing effect, and improving the accuracy and quality of grooving.

[0008] Furthermore, the reference base has a guide groove along its height direction facing the cutting blade. The pressing block is configured with an inverted L-shaped structure, with one side of the pressing block located in the guide groove and the other side of the pressing block located above the sealing strip. This ensures the horizontality of the pressing surface of the pressing block and its verticality during the lifting and lowering adjustment process, thereby improving the cutting accuracy.

[0009] Furthermore, the bevel grooving device also includes a cutting table. The tool adjustment assembly includes a lifting screw, a horizontal adjusting screw, and a lifting base. One end of the lifting screw passes through the cutting table and connects to the lifting base. One end of the horizontal adjusting screw passes through the lifting base and is fixed to the lifting cutting motor. The cutting motor is fixed to the outer side of the other side of the lifting base, and the output shaft of the cutting motor vertically passes through the cutting table and connects to the cutting blade. The horizontal adjusting screw can drive the cutting motor and the cutting blade to adjust the distance between the cutting blade and the reference surface in the horizontal direction. The lifting screw rotates in both directions to drive the lifting base, the horizontal adjusting screw, the cutting motor, and the cutting blade to rise and fall synchronously, thereby adjusting the height of the cutting blade. This design is convenient to operate, compact in structure, and improves the efficiency and accuracy of adjustment.

[0010] Furthermore, the tool adjustment assembly also includes two guide rods and two sliders. The two guide rods are fixedly positioned at a distance below the cutting table, and each guide rod is fitted with a slider. Each end of the lifting seat is connected to a slider and moves along the length of the guide rod, improving adjustment efficiency and stability.

[0011] Furthermore, the laser device includes a base, a lifting assembly disposed within the base, a laser assembly disposed above the base, and a rotation adjustment assembly. The lifting assembly includes a fixing member and a connecting rod unit. One end of the fixing member is fixed to the plate, and the other end of the fixing member is fixed to one end of the connecting rod unit. The other end of the connecting rod unit is hinged to the laser assembly. The lifting of the plate drives the fixing member to lift, which in turn drives the laser assembly to lift via the connecting rod unit. The laser beam of the laser assembly is located at the contact position between the edge banding and the plate. The laser beam of the laser assembly scans up and down to heat the adhesive on the edge banding based on the center position of the edge banding. The rotation adjustment assembly rotates in and out to rotate the laser assembly. The plate and the connecting rod unit are connected by the fixing member. Depending on the size of the edge banding, when adjusting the height of the plate, the fixing member pulls the connecting rod unit to automatically adjust the height of the laser assembly, ensuring that the laser starting point remains at the center of the edge banding. The adjusted laser component's laser scanning point is located at the center of the edge sealing tape and scans up and down based on the center of the edge sealing tape. This shortens the scanning stroke of the laser component, reduces the time it takes for the dry adhesive to heat up and adhere, and makes the dry adhesive on the edge sealing tape heat up more evenly during adhesion, thus improving the adhesion quality.

[0012] Furthermore, the linkage unit includes a swing arm, a support shaft, and a fixed arm. The upper end of the fixed arm is fixedly connected to the laser assembly, and the lower end of the fixed arm is hinged to one end of the swing arm. The other end of the swing arm is fixedly and rotatably connected to the other end of the fixing member. One end of the support shaft is fixed to the base, and the other end of the support shaft is rotatably connected to the center of the swing arm. Through the transmission of the linkage, a linked adjustment is achieved, improving the efficiency and accuracy of the adjustment.

[0013] Furthermore, the lifting assembly also includes two guide columns, a second lifting plate, and at least one pull rod. The two guide columns are fixedly disposed within the base, and both ends of the second lifting plate are fitted onto the corresponding guide columns. At least one pull rod is disposed on the second lifting plate, with its upper end fixed to the laser assembly. The lower end of the support shaft is fixed to the second lifting plate. The swing arm oscillates up and down via the support shaft to drive the second lifting plate, the pull rod, and the laser assembly to move up and down, improving stability and verticality during adjustment, thereby ensuring the accuracy of the adjustment.

[0014] An edge-banding method using an automatic edge-banding machine, comprising applying edge-banding tape to a board using any of the aforementioned automatic edge-banding machines, including:

[0015] Step S1: Adjust the height of the board and the laser irradiation angle of the laser device based on the width of the edge banding tape, so that the laser scanning point is located at the bonding point of the board and the edge banding tape; adjust the height of the cutting blade in the bevel grooving device based on the grooving position of the edge banding tape; adjust the pressing and cutting device to press the edge banding tape during the conveying process.

[0016] Step S2: The conveying component in the pressing and cutting device pulls the edge banding tape towards the board material direction, and the pressing component of the pressing and cutting device is adjusted to press and fix the edge banding tape.

[0017] Step S3: During the conveying process, the cutting blade of the bevel grooving device rotates to perform grooving on the edge banding; the distance between the cutting blade and the reference surface of the reference seat is fixed so that the thickness of the uncut portion of the edge banding at the grooving is the same.

[0018] Step S4: The laser scanning point of the laser device scans up and down from the center of the sealing tape to heat the dry adhesive at the bonding point of the sealing tape.

[0019] Step S5: The pressing device presses and adheres the melted edge banding tape onto the board. When the conveying length of the edge banding tape meets the edge banding length, the cutting component of the pressing and cutting device cuts the edge banding tape to complete the edge banding operation.

[0020] Furthermore, step S1 specifically includes:

[0021] Step S11: The conveyor frame for conveying the sheet material raises or lowers the sheet material to a set height according to the width of the edge banding tape; the fixing component of the laser device rises or falls together with the sheet material; the adjustment of the fixing component drives the linkage unit and the laser component on it to adjust the height, and under the action of the linkage unit, the height of the laser component is adjusted to half the height of the sheet material; the laser component is manually rotated based on the rotation adjustment component so that the laser scanning point is located at the contact point between the sheet material and the edge banding tape.

[0022] Step S12: According to the groove position of the edge banding tape, manually adjust the horizontal adjustment screw to drive the lifting seat and its cutting motor and cutting blade to move up and down synchronously, so that the cutting blade is located in the groove position of the edge banding tape, and lock the horizontal adjustment screw.

[0023] Step S13: The pressing and cutting device presses the sealing tape onto the conveyor table.

[0024] In summary, the beneficial effects of the present invention are as follows:

[0025] This invention uses an edge-sealing tape adhered to a reference surface, which is designed with an arc surface structure. This allows for a tighter fit of the edge-sealing tape, improving grooving accuracy. The distance between the cutting blade and the reference surface is adjusted based on the remaining uncut thickness of the edge-sealing tape at the grooving position. Only the initial adjustment of the distance between the cutting blade and the reference surface is required. This invention adapts to grooving operations with edge-sealing tapes of different thicknesses, ensuring that the remaining uncut thickness at the grooving position remains consistent across different thicknesses, thus improving equipment compatibility and grooving efficiency.

[0051] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0052] An automatic edge banding machine 1, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, it includes a conveyor frame 2, a pressing device 3, a pressing and cutting device 4, a laser device 5, a beveled grooving device 6, and a storage platform 7. The beveled grooving device 6 is located at the discharge port of the storage platform 7. The beveled grooving device 6 includes a reference base 61, a cutting blade 62, a cutting motor 63, and a blade adjustment assembly 64. The reference base 61 is located on one side of the edge sealing strip 8, and the side of the reference base 61 that contacts the edge sealing strip 8 is set as a reference surface 611 with an arc structure. The cutting blade 62 is located on the other side of the edge sealing strip 8. The output shaft of the cutting motor 63 is fixedly connected to the cutting blade 62, and the cutting blade 62 is used to groove the edge sealing strip 8. The blade adjustment assembly 64 is used to adjust the distance between the fixed cutting blade 62 and the reference surface 611 to reserve the thickness between the side of the edge sealing strip 8 located on the reference surface 611 and the bottom of the groove on the grooved side of the edge sealing strip 8.

[0053] The edge banding tape 8 is adhered to the reference surface 611, which is designed with an arc surface to ensure a tighter fit and improve grooving accuracy. The distance between the cutting blade 62 and the reference surface 611 is adjusted based on the remaining uncut thickness of the edge banding tape 8 at the grooving position. Only the initial adjustment of the distance between the cutting blade 62 and the reference surface 611 is required to accommodate grooving operations with edge banding tape 8 of different thicknesses. This ensures that the remaining uncut thickness of the edge banding tape 8 remains consistent at the grooving position, improving equipment compatibility and grooving efficiency.

[0054] In some embodiments, please refer to Figure 4 , Figure 5The beveled grooving device 6 also includes a pressure strip support 65, a push rod 66, and a pressing block 67. The pressure strip support 65 protrudes from the upper end of the reference base 61, the push rod 66 is slidably mounted on the pressure strip support 65, and the pressing block 67 is fixed below the push rod 66. The lower surface of the pressing block 67 abuts against the upper side of the sealing strip 8, thereby ensuring that the sealing strip 8 is stably attached to the reference surface 611 during grooving, so that the grooving position of the sealing strip 8 is on the same horizontal line, without any height difference, ensuring the sealing effect, and improving the accuracy and quality of grooving.

[0055] The reference base 61 has a guide groove 612 along its height direction facing the cutting blade 62. The pressing block 67 is configured with an inverted L-shaped structure, with one side of the pressing block 67 located in the guide groove 612 and the other side of the pressing block 67 located above the sealing strip 8. This ensures the horizontality of the pressing surface of the pressing block 67 and its verticality during the lifting and lowering adjustment process, thereby improving the cutting accuracy.

[0056] A groove 613 is provided below the guide groove 612, with the length of the groove 613 extending along the height direction. The groove 613 is positioned opposite to the cutting blade 62 to prevent damage to the cutting blade 62 due to operational errors. Specifically, the cutting edge of the cutting blade 62 is configured with a toothed structure, and the center of the cutting blade 62 is fitted onto the output shaft of the cutting motor 63.

[0057] In some embodiments, please refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 The bevel grooving device 6 also includes a cutting table 68. The tool adjustment assembly 64 includes a lifting screw 641, a horizontal adjustment screw 642, and a lifting base 643. One end of the lifting screw 641 passes through the cutting table 68 and connects to the lower end of the lifting base 643. One end of the horizontal adjustment screw 642 passes through the lifting base 643 and is fixed to the side of the cutting motor 63. The cutting motor 63 is fixed to the outer side of the other side of the lifting base 643, and the output shaft of the cutting motor 63 vertically passes through the cutting table 68 and connects to the cutting blade 62. The horizontal adjustment screw 642 can drive the cutting motor 63 and the cutting blade 62 to adjust the distance between the cutting blade 62 and the reference surface 611 in the horizontal direction. The lifting screw 641 rotates forward and backward to drive the lifting base 643, the horizontal adjustment screw 642, the cutting motor 63, and the cutting blade 62 to rise and fall synchronously, thereby adjusting the height of the cutting blade 62. This design is convenient to operate, compact in structure, and improves the efficiency and accuracy of adjustment.

[0058] Specifically, an anti-loosening nut 644 is provided at one end of the horizontal adjusting screw 642 that is fixed to the lifting seat 643. The anti-loosening nut 644 is fixed to the inner side of the other side of the lifting seat 643. The anti-loosening nut 644 is threadedly connected to the horizontal adjusting screw 642, which can effectively improve the stability of the structure and prevent the horizontal adjusting screw 642 from separating from the lifting seat 643 or from having a connection gap, thus affecting the adjustment effect.

[0059] The cutting motor 63 and the lifting seat 643 are connected by a motor support plate 650, and the end of the horizontal adjusting screw 642 is fixedly connected to the motor support plate 650. To improve the stability of the horizontal adjustment, multiple horizontal guide bars 649 are connected between the motor support plate 650 and the lifting seat 643. In this embodiment, four horizontal guide bars 649 are provided. One end of the horizontal guide bar 649 is fixed to the motor support plate 650, and the other end of the horizontal guide bar 649 is fixed inside the lifting seat 643. The motor support plate 650 and the cutting motor 63 move back and forth along the length direction of the horizontal guide bars 649 under the forward and reverse rotation of the horizontal adjusting screw 642 to adjust the distance between the cutting blade 62 and the reference surface 611.

[0060] In some embodiments, please refer to Figure 4 The tool adjustment assembly 64 also includes two guide rods 645 and two sliders 646. The two guide rods 645 are fixedly arranged at intervals below the cutting table 68, and a slider 646 is fitted on each guide rod 645. A slider 646 is connected to each end of the lifting seat 643 and moves along the length of the guide rod 645, improving the efficiency and stability of the adjustment.

[0061] An adjustment joint 647 is provided at one end of the horizontal adjustment screw 642 located on the outside of the lifting base 643 and at the upper end of the lifting screw 641. Users can use tools to lock the adjustment joint 647 to rotate the horizontal adjustment screw 642 or the lifting screw 641, making the adjustment operation more convenient and less labor-intensive.

[0062] Furthermore, a locking valve 648 can be provided at the end of both the horizontal adjusting screw 642 and the lifting screw 641 to facilitate fixing the horizontal adjusting screw 642 and the lifting screw 641 after adjustment, thereby improving the stability of the structure and the accuracy after adjustment, and preventing relative positional movement.

[0063] In some embodiments, please refer to Figure 4The upper end of the cutting table 68 includes a first cutting plate 681, a second cutting plate 682, and four bolt sets 683. The first cutting plate 681 and the second cutting plate 682 are arranged vertically at intervals. A reference base 61 is set on the first cutting plate 681, and one end of the lifting screw 641 passes through the first cutting plate 681 and the second cutting plate 682 in sequence and is connected to the lifting base 643. The output shaft of the cutting motor 63 passes through the first cutting plate 681 and the second cutting plate 682 in sequence and is connected to the cutting blade 62. The four corners of the first cutting plate 681 and the second cutting plate 682 are fixedly connected by a set of bolt sets 683, thereby adjusting the distance between the first cutting plate 681 and the second cutting plate 682 to adapt to different applications, and also adjusting the levelness of the first cutting plate 681 to improve the cutting accuracy and quality.

[0064] In some embodiments, please refer to Figure 5 The reference surface 61 of the reference base 61 is provided with a set of limiting and bonding components 69 on both sides. The bonding components 69 include a main pressure roller 691, a support column 692, a connecting shaft 693, a torsion spring 694, and a torsion block 695. The support column 692 is vertically arranged on one side of the reference base 61, the torsion block 695 is fixed to the support column 692, one end of the connecting shaft 693 is rotatably arranged on the support column 692, and the other end of the connecting shaft 693 is fixedly connected to the upper end of the main pressure roller 691. The side of the main pressure roller 691 and the reference surface 611 cooperate to clamp and limit the edge sealing strip 8. One end of the torsion spring 694 is fixed to the connecting shaft 693, and the other end of the torsion spring 694 is fixed to the torsion block 695. The elastic deformation force of the torsion spring 694 causes the connecting shaft 693 to drive the main pressure roller 691 to press and bond the edge sealing strip 8 to the reference surface 611, thereby improving the accuracy and efficiency of grooving.

[0065] In some embodiments, please refer to Figure 8 , Figure 9 , Figure 10 The pressing and cutting device 4 includes a conveying platform 41, a conveying assembly 42, a pressing assembly, and a cutting assembly 44. The conveying assembly 42 is used to convey the edge sealing tape 8, and the cutting assembly 44 is disposed on one side of the conveying assembly 42 for cutting the edge sealing tape 8. The pressing assembly includes multiple first pressing rods 431, a first lifting plate 432, and a lifting drive unit 433. The first lifting plate 432 is disposed below the conveying platform 41, and the multiple first pressing rods 431 are arranged at intervals along the conveying direction of the edge sealing tape 8. One end of the first pressing rod 431 is located above the edge sealing tape 8 to press the edge sealing tape 8, and the other end of the first pressing rod 431 passes through the conveying platform 41 and is fixed to the first lifting plate 432. The lifting drive unit 433 is disposed below the conveying platform 41 and is used to drive the first lifting plate 432 and the multiple first pressing rods 431 on it to move up and down synchronously to press the edge sealing tape 8.

[0066] Multiple first pressure rods 431 are arranged at intervals along the conveying direction of the sealing strip 8. The lower ends of the multiple first pressure rods 431 are fixed to the first lifting plate 432 below the conveying table 41. The lifting drive unit 433 drives the first lifting plate 432 and the multiple first pressure rods 431 on it to lift and lower synchronously to fix and press the sealing strip 8. The synchronous adjustment of the multiple first pressure rods 431 is more efficient and improves the overall pressing accuracy. Moreover, the up-and-down adjustment method is more compact, reduces the space occupied, and saves costs.

[0067] In some embodiments, please refer to Figure 10 , Figure 11 , Figure 12 The lifting drive unit 433 includes a mounting base 4331, a handle 4332, a first lead screw 4333, a steering mechanism 4334, and a second lead screw 4335. The mounting base 4331 is fixedly connected to the lower end of the conveyor table 41. The handle 4332 is connected to one end of the first lead screw 4333. The other end of the first lead screw 4333 passes through the mounting base 4331 and is connected to one side of the steering mechanism 4334. The steering mechanism 4334 converts the horizontal force of the first lead screw 4333 into a vertical force to drive the second lead screw 4335 to rotate. One end of the second lead screw 4335 is connected to the lower side of the steering mechanism 4334, and the other end is threaded to the first lifting plate 432. The length direction of the first lead screw 4333 is horizontal, and the length direction of the second lead screw 4335 is vertical. The structure is simple, and adjustment and operation are more convenient.

[0068] In use, manually rotate the handle 4332 in both directions. The handle 4332 drives the first lead screw 4333 to rotate. The horizontal force is converted into a vertical force through the steering device 4334 to drive the second lead screw 4335 to rotate. The forward and reverse rotation of the second lead screw 4335 drives the first lifting plate 432 and its multiple first pressure rods 431 to rise and fall synchronously.

[0069] To improve stability during the lifting process, the lifting drive unit 433 also includes a balance plate 4336 and multiple guide rods 4337. The balance plate 4336 is fixed below the mounting base 4331. The multiple guide rods 4337 are spaced apart between the balance plate 4336 and the first lifting plate 432. One end of each guide rod 4337 is fixed to the balance plate 4336, and the other end passes through the first lifting plate 432. The multiple guide rods 4337 guide the lifting motion of the first lifting plate 432. The other end of the second lead screw 4335 passes through the balance plate 4336 and connects to the first lifting plate 432, improving the efficiency, verticality, and accuracy of the lifting process.

[0070] Specifically, the balance plate 4336 is designed with an L-shaped structure and three guide rods 4337. One guide rod 4337 is set at each end of the balance plate 4336 and at the corner. The three guide rods 4337 are arranged in a triangle, which is compact and cost-effective. It can ensure that the periphery of the first lifting plate 432 can be raised and lowered synchronously, thereby improving the efficiency and accuracy of the lifting.

[0071] In some embodiments, please refer to Figure 11 The first pressure rod 431 includes a vertical rod 4311, a pressing shaft 4312, and a clamping block 4313. One end of the vertical rod 4311 passes sequentially through the conveyor table 41 and the first lifting plate 432, and is fixedly mounted on the first lifting plate 432 by the clamping block 4313. One end of the pressing shaft 4312 is fixed to the other end of the vertical rod 4311, and the length direction of the pressing shaft 4312 is perpendicular to the length direction of the vertical rod 4311. The pressing shaft 4312 is used to press the edge sealing tape 8. The structure is simple and improves space utilization.

[0072] A pressure roller 435 is also provided on the side of the first pressure rod 431 located near the conveying direction. The pressure roller 435 cooperates with the side wall of the guide table 411 protruding from the conveying table 41 to tension the sealing strip 8, thereby improving the conveying quality and efficiency of the sealing strip 8.

[0073] In some embodiments, please refer to Figure 11 , Figure 12 The edge-pressing assembly also includes a second pressing rod 434 disposed on one side of the cutting assembly 44. The second pressing rod 434 includes a rod body 4341, a pressing plate 4342, and a connecting block 4343. One end of the connecting block 4343 is fixed to the first lifting plate 432, and the other end of the connecting block 4343 protrudes from the first lifting plate 432. One end of the rod body 4341 passes through the conveyor table 41 and is fixed to the connecting block 4343, while the other end of the rod body 4341 is provided with the pressing plate 4342. The length direction of the pressing plate 4342 is the same as the length direction of the edge-sealing tape 8, increasing the pressing area of ​​the edge-sealing tape 8 at the position of the cutting assembly 44, thereby improving the stability of the pressing and improving the efficiency and quality of cutting. Specifically, there are two first pressing rods 431 and one second pressing rod 434.

[0074] In some embodiments, please refer to Figure 9The pressing and cutting device 4 is also equipped with an anti-tipping component 45, which includes a fixed column 451, a limiting block 452, a swing block 453, and a rotating wheel 454. The fixed column 451 is set on the conveyor table 41. One end of the limiting block 452 is fixed to the fixed column 451, and the other end of the limiting block 452 is provided with a movable groove. One end of the swing block 453 is rotatably set in the movable groove along the conveying direction. The length direction of the swing block 453 is inclined along the conveying direction of the sealing strip 8. The rotating wheel 454 is rotatably set at the other end of the swing block 453. The circumference of the rotating wheel 454 is in contact with the side of the sealing strip 8, which can effectively ensure the quality of the conveyed sealing strip 8 and prevent the sealing strip 8 from falling back due to external force, thus affecting the quality of the previous sealing strip 8.

[0075] In some embodiments, please refer to Figure 10 , Figure 11 , Figure 12 The conveying assembly 42 includes a conveying motor 421, a first gear 422, a second gear 423, a connecting plate 424, and a conveying wheel 425. The output shaft of the conveying motor 421 passes through the first gear 422 and is connected to the connecting plate 424 by a bearing. The circumference of the first gear 422 meshes with the circumference of the second gear 423. One end of the conveying wheel 425 passes through the connecting plate 424 and is fixedly mounted on the upper side of the second gear 423, and is connected to the connecting plate 424 by a bearing. The first gear 422, the second gear 423, and the conveying wheel 425 are cylindrical structures. The side of the conveying wheel 425 is in frictional contact with the side of the sealing strip 8, which facilitates the stable movement of the sealing strip 8 along the conveying direction and also ensures that the conveying wheel 425 will not damage the sealing strip 8, thereby improving the conveying quality of the sealing strip 8.

[0076] Among them, a fixed wheel 426 is provided on the side of the conveyor wheel 425 at intervals. The sealing strip 8 is located between the fixed wheel 426 and the conveyor wheel 425. Under the driving force of the conveyor motor 421, the first gear 422 drives the second gear 423 to rotate, the second gear 423 drives the conveyor wheel 425 to rotate, and the friction between the conveyor wheel 425 and the side of the sealing strip 8 causes the sealing strip 8 to move along the conveying direction.

[0077] In some embodiments, a lug 427 protrudes from one end of the connecting plate 424 near the conveyor wheel 425. The conveying assembly 42 also includes a cylinder 428 and a fixing block 429. The cylinder 428 is disposed below the conveyor table 41, and the output shaft of the cylinder 428 is connected to one end of the fixing block 429, while the other end of the fixing block 429 is hinged to the lug 427. The cylinder 428 is used to drive the connecting block 4343 and the conveyor wheel 425 to rotate about the center of the output shaft of the conveyor motor 421 to move away from or close to the sealing strip 8, which facilitates the adjustment of the position of the conveyor wheel 425 to accommodate sealing strips 8 of different thicknesses, improves compatibility, and facilitates the initial laying of the sealing strip 8 along the conveying direction.

[0078] In some embodiments, please refer to Figure 9 , Figure 10 The cutting assembly 44 is positioned between the conveying assembly 42 and the second pressure bar 434. A material sensor 442 is installed on one side of the second pressure bar 434 to detect whether the edge sealing tape 8 has been conveyed to the correct position, thereby improving cutting efficiency. The cutter 441 of the cutting assembly 44 can cut the edge sealing tape 8 according to actual needs.

[0079] In some embodiments, such as Figure 13 , Figure 14 As shown, the laser device 5 includes a base 51, a lifting assembly 52 disposed within the base 51, and a laser assembly 53 disposed above the base 51. The lifting assembly 52 includes a fixing member 521 and a connecting rod unit 522. One end of the fixing member 521 is fixed to the plate 9, and the other end is fixed to one end of the connecting rod unit 522. The other end of the connecting rod unit 522 is hinged to the laser assembly 53. The lifting of the plate 9 drives the fixing member 521 to lift, which in turn drives the laser assembly 53 to lift via the connecting rod unit 522. The laser of the laser assembly 53 is located at the contact point between the sealing tape 8 and the plate 9. The laser of the laser assembly 53 scans up and down to heat the adhesive on the sealing tape based on the center position of the sealing tape. The plate 9 and the connecting rod unit 522 are connected by the fixing member 521. Depending on the size of the sealing tape 8, when adjusting the height of the plate 9, the fixing member 521 pulls the connecting rod unit 522, causing the laser assembly 53 to automatically adjust its height, ensuring that the laser starting point remains at the center of the sealing tape 8. The laser scanning point of the adjusted laser component 53 is located at the center of the edge sealing tape 8 and scans up and down based on the center of the edge sealing tape 8. This can shorten the scanning stroke of the laser component 53, shorten the time for the dry adhesive to heat up and stick, and make the dry adhesive on the edge sealing tape 8 heat up more evenly during sticking, thus improving the sticking quality.

[0080] In some embodiments, please refer to Figure 14 , Figure 15 , Figure 16 The linkage unit 522 includes a swing arm 5221, a support shaft 5222, and a fixed arm 5223. The upper end of the fixed arm 5223 is fixedly connected to the laser assembly 53, and the lower end of the fixed arm 5223 is hinged to one end of the swing arm 5221. The other end of the swing arm 5221 is fixedly and rotatably connected to the other end of the fixing member 521. One end of the support shaft 5222 is fixed to the base 51, and the other end of the support shaft 5222 is rotatably connected to the center of the swing arm 5221. Through the transmission of the linkage, the adjustment is linked, improving the efficiency and accuracy of the adjustment.

[0081] In some embodiments, please refer to Figure 15 , Figure 16The support shaft 5222 is vertically arranged, and the other end of the support shaft 5222 is provided with a first thread. The other end of the support shaft 5222 is also provided with a first connector 5224. One end of the first connector 5224 is threaded to the first thread, and the other end of the support shaft 5222 is rotatably connected to the inner hole on the swing arm 5221, which facilitates the adjustment of the height of the swing arm 5221, adapts to different needs, and has stronger compatibility.

[0082] Specifically, the first connecting part 5224 includes a threaded portion and a movable portion. The threaded portion is a cylindrical structure and is fitted onto the support shaft 5222. Both ends of the threaded portion are threadedly connected to the first thread by nuts to fix it to the support shaft 5222. A mounting shaft protrudes from the side of the threaded portion facing the swing arm 5221. The movable portion is a wheel-shaped structure, and its center is fitted onto the mounting shaft, making the connection more stable. Furthermore, the movable portion is rotatably disposed within an inner hole, reducing friction and allowing it to swing at any angle, improving the flexibility and accuracy of the swing.

[0083] In some embodiments, please refer to Figure 14 , Figure 15 The fixing component 521 includes a fixing plate 5211, a fixing rod 5212, and a second connecting component 5213. The fixing plate 5211 is screwed to the plate 9. One end of the fixing rod 5212 is connected to the fixing plate 5211, and a second thread is provided on the periphery of the fixing rod 5212. The second connecting component 5213 is threaded to the second thread on the fixing rod 5212. The side of the second connecting component 5213 is rotatably connected to the other end of the swing arm 5221, which facilitates the adjustment of the position of the lifting component 52 and the rough adjustment of the height of the laser component 53 according to the actual installation height, resulting in stronger compatibility and a wider adjustable range. The structure of the second connecting component 5213 is the same as that of the first connecting component 5224, and the specific details can be found in the relevant content of the first connecting component 5224 described above.

[0084] In some embodiments, please refer to Figure 15 , Figure 16The lifting assembly 52 also includes two guide posts 523, a second lifting plate 524, and at least one pull rod 525. The two guide posts 523 are fixedly installed within the base 51, and both ends of the second lifting plate 524 are fitted onto the corresponding guide posts 523. The lower ends of the guide posts 523 are fixedly connected to the bottom of the base 51, and the upper ends are fixed to the mounting plate 511 with screws. At least one pull rod 525 is provided on the second lifting plate 524, and the upper end of the pull rod 525 is fixed to the laser assembly 53. The lower end of the support shaft 5222 is fixed to the second lifting plate 524. The swing arm 5221 swings up and down via the support shaft 5222 to drive the second lifting plate 524, pull rod 525, and laser assembly 53 to move up and down, improving the stability and verticality of the adjustment process and ensuring the accuracy of the adjustment. Specifically, there are two pull rods 525, located between the two guide posts 523. The upper end of the pull rod 525 passes through the mounting plate 511 and is fixed to the lower end of the encapsulation shell 531.

[0085] In some embodiments, the lower end of the support shaft 5222 passes through the second lifting plate 524 and is fixedly connected to a limiting member 526, which can prevent damage to parts due to over-adjustment, extend service life, and improve safety. Specifically, the limiting member 526 includes a limiting block 452 and a limiting wheel. The limiting block 452 is fixed to the lower end of the support shaft 5222, and the limiting wheel is rotatably disposed at the lower end of the limiting block 452, serving as a buffer.

[0086] In some embodiments, please refer to Figure 15 A mounting plate 511 is disposed above the base 51. The laser assembly 53 includes a housing 531 and a laser. The laser is used to emit laser light and is fixed inside the housing 531. The side of the housing 531 is provided with mounting holes 5311 for the laser to pass through. The mounting plate 511 is disposed on the base 51, and the lower end of the housing 531 is connected to the mounting plate 511 by a bearing, which facilitates rotation and adjustment of the angle of the laser emitted by the laser so that the scanning point of the laser is more closely aligned with the contact point between the sealing tape 8 and the plate 9.

[0087] In some embodiments, please refer to Figure 14 , Figure 15 , Figure 16To improve the efficiency and accuracy of laser angle adjustment, the laser device 5 also includes a rotary adjustment assembly 54. The rotary adjustment assembly 54 includes an adjustment lever 541, an adjustment seat 542, and a swing plate 543. The adjustment seat 542 is fixed to the mounting plate 511, and the adjustment lever 541 is fixed to the adjustment seat 542. One end of the adjustment lever 541 passes through the adjustment seat 542 and connects to one end of the swing plate 543. The other end of the swing plate 543 is fixed to the outside of the encapsulation shell 531. Rotating the adjustment lever 541 in and out drives the encapsulation shell 531 and the laser inside it to rotate, thereby improving the efficiency and accuracy of adjustment.

[0088] The other end of the adjusting rod 541 can be equipped with a handle 544 and a locking rod 545. After the handle 544 rotates the adjusting rod 541 to its final position, the locking rod 545 is locked to prevent the adjusting rod 541 from rotating, thus improving the stability after adjustment. Simultaneously, a digital display base 546 is provided on the adjusting rod 541 to facilitate understanding of the current adjustment status and the orientation of the laser's scanning point, thereby improving adjustment efficiency.

[0089] The upper end of the encapsulation shell 531 is provided with an air blowing hole 5312, which is connected to an external air blowing device to improve the heat dissipation effect inside the encapsulation shell 531. The air blowing device blows gas into the air blowing hole 5312, then flows through the interior of the encapsulation shell 531 and flows out through the mounting hole 5311 to the outside, which can carry away the internal heat and achieve good cooling and dust removal effects.

[0090] First, based on the width adjustment of the edge banding tape 8 and the height of the board 9, the raising or lowering of the board 9 causes the fixing part 521 to rise or fall, which can realize that the adjustment height of the laser component 53 is half the adjustment height of the board 9, improving the adjustment efficiency, saving costs and space, and making the structure more compact.

[0091] Specifically, when plate 9 rises, fixing member 521 rises, and the end of the swing arm connected to fixing rod 5212 lifts upward. Since fixing arm 5223 is fixed to mounting plate 511, swing arm 5221 drives support shaft 5222 to move upward, and support shaft 5222 pulls second lifting plate 524, pull rod 525, and laser component 53 to rise simultaneously. When plate 9 falls, fixing member 521 falls, and the end of the swing arm connected to fixing rod 5212 moves downward. Since fixing arm 5223 is fixed to mounting plate 511, swing arm 5221 presses support shaft 5222 downward, and support shaft 5222 pulls second lifting plate 524, pull rod 525, and laser component 53 to fall simultaneously.

[0092] Secondly, based on the bonding point position of the board 9 and the edge banding tape 8, the scanning point position of the laser is manually adjusted so that the laser scanning point is closer to the bonding point.

[0093] Specifically, the adjusting lever 541 is rotated according to the current scanning point position. Rotating the adjusting lever 541 in and out can push the swing plate 543 to rotate clockwise or counterclockwise, thereby driving the encapsulation shell 531 and the laser on it to rotate around the bearing connected to the mounting plate 511 as the axis. This makes the scanning point of the laser after adjustment located at the bonding point between the plate 9 and the edge sealing tape 8. The scanning point of the laser heats and melts the soft adhesive coated on the edge sealing tape 8, and then promptly applies it to the plate 9, improving the bonding quality.

[0094] An edge-sealing method for an automatic edge-sealing machine 1 is described in the following reference: Figure 17 The edge banding machine 1 described above is used to attach the edge banding tape 8 to the board 9, which includes:

[0095] Step S1: Adjust the height of the board 9 and the laser irradiation angle of the laser device 5 based on the width of the edge banding 8 so that the laser scanning point is located at the bonding point of the board 9 and the edge banding 8; adjust the height of the cutting blade 62 in the bevel grooving device 6 based on the grooving position of the edge banding 8; adjust the pressing and cutting device 4 to press the edge banding 8 during the conveying process.

[0096] Step S2: The conveying component 42 in the pressing and cutting device 4 pulls the edge banding 8 towards the board 9, and the pressing component of the pressing and cutting device 4 is adjusted to press and fix the edge banding 8.

[0097] Step S3: During the conveying process, the cutting blade 62 of the bevel grooving device 6 rotates to perform grooving on the edge sealing strip 8; the distance between the cutting blade 62 and the reference surface 611 of the reference seat is fixed so that the thickness of the uncut part of the edge sealing strip 8 at the grooving is the same.

[0098] Step S4: The laser scanning point of the laser device scans up and down with the center of the sealing tape 8 as the starting point, heating the dry adhesive of the sealing tape at the bonding point.

[0099] Step S5: The pressing device 3 presses and adheres the edge banding tape 8, which has been melted with dry adhesive, onto the board 9; when the conveying length of the edge banding tape 8 meets the edge banding length, the cutting component 44 of the pressing and cutting device 4 cuts the edge banding tape 8 to complete the edge banding operation.

[0100] The laser device 5 can automatically adjust its height according to the width of the edge banding tape 8, ensuring that the scanning point of the laser device 5 always starts from the center of the edge banding tape 8. This ensures more uniform heating of the dry adhesive on the bonding surface of the edge banding tape 8 and ensures the degree of melting of the dry adhesive on the top and bottom sides of the edge banding tape 8, resulting in a better bonding effect. The beveled grooving device 6 can perform grooving operations on the edge banding tape 8. The cutting blade 62 only needs to adjust its distance from the reference surface 611 during initial use, which can adapt to edge banding tapes 8 of different thicknesses, thus enhancing compatibility. The pressure feeding and cutting device 4 can simultaneously raise and lower multiple pressing points to press and fix the edge banding tape 8, preventing it from warping or bending during transportation and improving the efficiency of board application.

[0101] In some embodiments, step S1 specifically includes:

[0102] Step S11: The conveyor frame 2, which transports the sheet material 9, raises or lowers the sheet material 9 to a set height according to the width of the edge banding tape 8. The fixing component 521 of the laser device 5 rises or falls together with the sheet material 9, automatically adjusting for higher efficiency. The adjustment of the fixing component 521 drives the linkage unit 522 and its laser component 53 to adjust their height. Under the action of the linkage unit 522, the height of the laser component 53 is adjusted to half the height of the sheet material 9, resulting in a compact structure and space saving. The laser component 53 is manually rotated based on the rotation adjustment component 54 so that the laser scanning point is located at the joint between the sheet material 9 and the edge banding tape 8, making the dry adhesive at the joint more even and improving the bonding quality.

[0103] Step S12: According to the slotting position of the edge banding tape 8, manually adjust the horizontal adjusting screw 642 to drive the lifting seat 643 and its cutting motor 63 and cutting blade 62 to move up and down synchronously, so that the cutting blade 62 is located in the slotting position of the edge banding tape 8. Lock the horizontal adjusting screw 642. The height of the cutting blade 62 can be adjusted according to the actual required slotting height. The operation is simple and the compatibility is stronger.

[0104] Step S13: The pressing and cutting device 4 presses the sealing strip 8 onto the conveyor table 41. Rotating the first lead screw 4333 drives the second lead screw 4335 to pull the second lifting plate 524, causing the two first pressure rods 431 and second pressure rods 434 to descend. This presses the sealing strip 8 onto the conveyor table 41, allowing for synchronous adjustment, higher efficiency, and improved overall pressing accuracy. Furthermore, the up-and-down adjustment method results in a more compact structure, reducing space requirements and saving costs.

[0105] In step S2, the conveying component 42 in the pressing and cutting device 4 pulls the edge sealing strip 8 towards the plate 9, and the pressing component of the pressing and cutting device 4 is adjusted to press and fix the edge sealing strip 8.

[0106] The following is a detailed explanation of this step.

[0107] The manual forward and reverse rotation handle 4332 drives the first lead screw 4333 to rotate, which in turn converts the horizontal force into a vertical force through the steering mechanism 4334, thereby driving the second lead screw 4335 to rotate. The forward and reverse rotation of the second lead screw 4335 drives the second lifting plate 524 and its multiple first pressure rods 431 and second pressure rods 434 to rise and fall synchronously along the length of the guide rod, so that the pressing plate 4342 and the pressing shaft 4312 are pressed tightly against the upper side of the sealing strip 8. The cylinder 428 drives the connecting block 4343 and the conveyor wheel 425 to rotate around the center of the output shaft of the conveyor motor 421 to fit tightly against the sealing strip 8, making the sealing strip 8 fit more tightly against the conveyor wheel 425, improving the transmission of force and the stability of the conveying of the sealing strip 8. Then, under the driving force of the conveyor motor 421, the first gear 422 drives the second gear 423 to rotate, the second gear 423 drives the conveyor wheel 425 to rotate, and the friction between the conveyor wheel 425 and the side of the sealing strip 8 causes the sealing strip 8 to move along the conveying direction.

[0108] In step S3, during the conveying process, the cutting blade 62 of the bevel grooving device 6 rotates to perform grooving on the edge sealing strip 8. The distance between the cutting blade 62 and the reference surface 611 of the reference base is fixed so that the thickness of the uncut portion of the edge sealing strip 8 at the grooving is uniform.

[0109] The following is a detailed explanation of this step.

[0110] Users can use tools to lock the adjusting joint 647 to rotate the horizontal adjusting screw 642 or the lifting screw 641 to adjust the position of the cutting blade 62. Rotating the horizontal adjusting screw 642 can drive the cutting motor 63 to move horizontally, thereby adjusting the distance between the cutting head of the cutting blade 62 and the reference surface 611. Through multiple grooving tests, the remaining uncut thickness is checked to determine whether the cutting blade 62 is properly adjusted. Then, by closing the locking valve 648 on the horizontal adjusting screw 642, the horizontal adjusting screw 642 is fixed to fix the horizontal position of the cutting blade 62.

[0111] Users can use tools to lock the adjusting joint 647 on the lifting screw 641 to rotate it in both directions, thereby driving the horizontal adjusting screw 642, lifting seat 643, cutting motor 63, and cutting blade 62 to move up and down synchronously along the lifting screw 641, thus adjusting the height of the cutting blade 62. Once the appropriate height is reached, the locking valve 648 on the lifting screw 641 is closed to fix the lifting screw 641, thereby locking the position of the cutting blade 62.

[0112] After the position of the cutting blade 62 is adjusted, the cutting motor 63 starts and drives the cutting blade 62 to rotate. The cutting blade 62 performs grooving operation on the edge banding tape 8 that is attached to the reference seat 61. The edge banding tape 8 is cut and then conveyed towards the board 9 under the traction of the conveyor wheel 425.

[0113] In step S4, the laser scanning point of the laser device scans up and down with the center of the sealing strip 8 as the starting point, heating the dry adhesive of the sealing strip located at the bonding point.

[0114] The following is a detailed explanation of this step.

[0115] First, when the plate 9 rises, the fixing member 521 rises, and the end of the swing arm connected to the fixing rod 5212 lifts upward. Since the fixing arm 5223 is fixed to the mounting plate 511, the swing arm 5221 drives the support shaft 5222 to move upward, and the support shaft 5222 pulls the second lifting plate 524, the pull rod 525, and the laser component 53 to rise simultaneously. When the plate 9 falls, the fixing member 521 falls, and the end of the swing arm connected to the fixing rod 5212 moves downward. Since the fixing arm 5223 is fixed to the mounting plate 511, the swing arm 5221 presses the support shaft 5222 to move downward, and the support shaft 5222 pulls the second lifting plate 524, the pull rod 525, and the laser component 53 to fall simultaneously. The support shaft 5222 is located at the center of the swing arm 5221, which allows the adjustment height of the laser component 53 to be half the adjustment height of the plate 9, thereby improving the adjustment efficiency, saving costs and space, and making the structure more compact.

[0116] Secondly, the adjusting lever 541 is rotated according to the current scanning point position. The rotation of the adjusting lever 541 can drive the swing plate 543 to rotate clockwise or counterclockwise, thereby driving the encapsulation shell 531 and the laser on it to rotate around the bearing connected to the mounting plate 511 as the axis. This makes the scanning point of the laser after adjustment located at the bonding point between the plate 9 and the edge sealing tape 8. The scanning point of the laser heats and melts the soft adhesive coated on the edge sealing tape 8, and then promptly applies it to the plate 9, improving the bonding quality.

[0117] In step S5, the pressing device 3 presses the edge banding tape 8, with the molten adhesive just applied, onto the board 9. When the edge banding of the board 9 is almost finished, according to the set length of the edge banding tape 8, the cutter 441 of the cutting component 44 of the pressing and cutting device 4 cuts the edge banding tape 8, the conveying motor 421 stops working, and the pressing device 3 applies the remaining edge banding tape 8 onto the board 9, completing this edge banding operation.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
