Technical Field

[0001] The invention relates to the field of artwork manufacturing equipment, and in particular to a rotary worktable of a laser engraving machine. Background Art

[0002] Artwork carving is a general term for the three creative methods of carving, engraving and molding. It refers to the use of various plastic materials (such as plaster, resin, clay, etc.) or hard materials that can be carved and engraved (such as wood, stone, metal, jade, agate, etc.) to create a visual and tangible artistic image with a certain space, so as to reflect social life and express the artist's aesthetic feelings, aesthetic emotions and aesthetic ideals. Artwork carving has a long history. As early as the late Paleolithic Age, humans began to use bone, stone and other materials for carving, creating primitive stone carvings, bone carvings and other works. With the passage of time, carving techniques have gradually become richer, forming a variety of schools and styles. In China, carving arts such as jade carving, stone carving and wood carving have been highly developed, and a large number of excellent carving works have emerged. With the increasing demand for artworks, the use of machine carving has become the first choice for expanding production and increasing efficiency.

[0027] Embodiment 1, as Figure 1-Figure 4As shown, a laser engraving machine rotary worktable proposed by the present invention includes a support cylinder 1, a positioning dust removal component 5, a protective cover 3 and a workstation planning frame 4. A rotating operating panel 2 is arranged at the mouth of the support cylinder 1, and an exhaust dust removal component 6 is arranged at the bottom of the cylinder. Multiple groups of positioning dust removal components 5 are arranged on the operating panel 2 around the rotation center, and each group of positioning dust removal components 5 includes a dust removal cylinder 503 that is rotatably connected to the exhaust dust removal component 6, a flip disk 501 that is flipped and arranged on the mouth of the dust removal cylinder 503, and two groups of clamping members 502 located on the flip disk 501; the flip disk 501 can adjust the engraving angle on the one hand by flipping, and promote dust to enter the dust removal cylinder 503 on the other hand; multiple groups of movably installed clamping rods 511 are arranged on the two groups of clamping members 502, and the multiple groups of clamping rods 511 are lifted and translated as a whole, on the one hand On the one hand, the position of the clamping surface is adjusted, and on the other hand, the shape of the clamping surface is adjusted to fit the surface of the artwork and assist in clamping; the protective cover 3 is set as a double-layer rotating opening and closing structure, which is covered on the outer periphery of the tube mouth of the support tube 1 to form an engraving room; the workstation planning frame 4 is located in the protective cover 3, and its position is opposite to the positioning dust removal component 5. The front and rear workstations are respectively used to install the laser engraver 9 and the detector 8, and the left and right workstations are used to install the fan 10 to form a wind wall to isolate the front and rear working spaces. The front working space is used for laser engraving, and the rear working space is used to detect the engraving effect.

[0028] like Figure 4 As shown, the protective cover 3 includes an inner half cover body 302 fixed on the support tube 1 and an outer half cover body 301 which is rotated and arranged on the inner half cover body 302 through the drive of a motor 303 .

[0029] It should be further explained that both the inner half cover body 302 and the outer half cover body 301 are cylindrical structures with a notch; the notch of the inner half cover body 302 faces forward, and a fixed seat 305 for installing the power supply machine 303 is provided on the notch; a rotating seat 304 is provided on the outer half cover body 301, which is rotatably connected to the fixed seat 305 and connected to the main shaft of the motor 303; the fixed seat 305 and the rotating seat 304 are both located on the central axis of the support tube 1 and the operating panel 2.

[0030] Before and after engraving, the motor 303 is driven, and the notches of the inner half cover 302 and the outer half cover 301 are opposite or staggered, so that the opening and closing of the engraving chamber can be controlled.

[0031] like Figure 4 As shown, the workstation planning frame 4 includes a mounting ring 401 which is sleeved on the outer periphery of the motor 303 and connected to the inner half cover 302, and four sets of frames 402 arranged in front, behind, left and right of the mounting ring 401; the four sets of frames 402 distinguish the workstations in the engraving room.

[0032] The laser engraver 9 is slidably mounted on the front frame 402 to laser engrave the artwork on the lower positioning dust removal component 5; the detector 8 is slidably mounted on the rear frame 402 to detect the engraving effect of the artwork on the lower positioning dust removal component 5; the fan 10 spans the mounting ring 401 and extends on the left and right frames 402 to remove dust and cool the artwork on the lower positioning dust removal component 5, while intercepting dust from entering the rear of the engraving room.

[0033] It should be further explained that the detector 8 is an industrial camera, which has high precision, high stability and high reliability, and is suitable for long-term work in harsh industrial environments. Industrial cameras are usually equipped with high-resolution sensors that can capture the subtle details of the engraved works, such as textures, lines and shapes. In this embodiment, by setting up the detector 8, the engraving effect of the engraved artwork can be confirmed. When engraving problems are found, the engraving room can be returned to the front and the laser engraver 9 can be used to correct them.

[0034] It should be further explained that the artwork needs to pass through the wind wall when moving in front and behind the carving room to remove dust. At the same time, the wind wall can reduce the dust from entering the back of the carving room, preventing the detector 8 from being covered by dust and interfering with the field of vision.

[0035] It should be further explained that a motor 2 and a lead screw 1 driven to rotate by the motor 2 are arranged on the frame 402 on the front and rear sides; a slider threadedly connected to the lead screw 1 is arranged on the lead screw 1; the laser engraver 9 and the detector 8 are detachably mounted on the sliders on the front and rear sides to achieve forward and backward movement, thereby increasing the range of engraving and detection.

[0036] It needs to be further explained that if Figure 5 As shown, a driving structure 7 for driving the operating plate 2 and the dust removal cylinder 503 to rotate respectively is arranged on the support cylinder 1. The driving structure 7 comprises a gear 1 704 located at the center of the operating plate 2, a gear ring 1 703 sleeved on the outer periphery of the dust removal cylinder 503, a gear ring 2 701 arranged around the outer periphery of the operating plate 2, and a gear 2 702 located below the gear ring 2 701; the gear 1 704 is driven to rotate by the motor 3 and meshes with the gear ring 1 703 in sequence; the gear 2 702 is driven to rotate by the motor 4 and meshes with the gear ring 2 701.

[0037] By meshing gear 1 704 with gear ring 1 703, the dust removal cylinder 503 can rotate to adjust the engraving or detection angle, and by meshing gear 2 702 with gear ring 2 701, the operating panel 2 can rotate to adjust the position of the dust removal assembly 5 to switch the workstation.

[0038] like Figure 6-Figure 8As shown, the dust collecting cylinder 503 is vertically penetrated and rotatably arranged on the operation panel 2, the cylinder mouth is connected to the through hole 201 and is provided with a dust collecting box 504, and the bottom of the cylinder is connected to the exhaust dust collector 601 on the exhaust dust collecting part 6 through the pipe 603; the flip plate 501 is rotatably arranged on the box mouth of the dust collecting box 504; the dust collecting box 504 is hemispherical, and is connected to the bottom of the dust collecting cylinder 503 through the hollow 506 with a filter screen 1 arranged on the side wall, and the sundries that cannot pass through the screen are received through the bottom space; when the flip plate 501 rotates, one end rises and the other end sinks, and the sinking end extends into the dust collecting box 504, and the dust generated by the engraving is introduced into the dust collecting box 504, and the pipe 603 can suck the dust into the exhaust dust collector 601. The rotation of the flip plate 501 can also adjust the inclination angle of the artwork to meet different engraving requirements.

[0039] It should be further explained that the flip plate 501 is configured as a circular structure that matches the opening of the dust collecting box 504; a filter screen 2 505 is disposed in the center of the circular structure, and a rotating shaft 507 driven to rotate by a motor 3 is disposed along the diameter direction of the flip plate 501 to drive it to flip from both sides; two sets of clamps 502 are located on both sides of the filter screen 2 505.

[0040] It should be further explained that the two groups of clamping members 502 are parallel to each other and perpendicular to the rotation axis 507 .

[0041] As the dust collecting cylinder 503 rotates, the reversing plate 501 turns over, and the artworks clamped by the two sets of clamping members 502 move synchronously. Since the two sets of clamping members 502 are perpendicular to the rotating shaft 507, when the reversing plate 501 turns over, the reversing side is unobstructed, so that the dust can slide along the surface of the reversing plate 501 into the dust collecting box 504. In addition, the second filter 505 can also be used to assist dust collection.

[0042] like Fig. 9 As shown, the clamping member 502 includes a lifting platform 513 that vertically penetrates the flip disk 501; the mounting plate 509 is arranged on the lifting platform 513 and moves up and down synchronously with it; the cylinder 512 is arranged on the mounting plate 509; the clamping seat 508 is driven by the cylinder 512 and moves in front of the mounting plate 509; the clamping rod 511 is horizontally penetrated on the clamping seat 508 and can slide horizontally under the push of external force; a positioning member that acts on the clamping rod 511 is arranged on the clamping seat 508.

[0043] It should be further explained that a lifting seat 514 is set at the bottom of the lifting platform 513; a screw 2 510 threadedly connected to the lifting seat 514 is set; the screw 2 510 is driven to rotate by a motor 4 to drive the lifting platform 513 to move up and down and adjust the clamping height of the clamping rod 511.

[0044] Since the clamping rod 511 can be pushed, before clamping, the cylinder 512 drives the clamping seat 508 to move back close to the mounting plate 509, so that all the clamping rods 511 are all toward the center of the flip plate 501, and the ends of all the clamping rods 511 are on the same horizontal plane. Then the cylinder 512 drives the clamping seat 508 to move forward close to the artwork, and all the clamping rods 511 gradually contact the surface of the artwork. The clamping rods 511 that contact the convex surface stop moving forward, and at the same time, the clamping seat 508 slides along the stationary clamping rods 511, so that the clamping rods 511 that contact the concave surface continue to move forward. Finally, all the clamping rods 511 are in contact with the surface of the artwork, forming a clamping surface consistent with its appearance. The positioning piece fixes the formed clamping surface, and the artwork can be clamped and positioned.

[0045] It should be further explained that the multiple groups of clamping rods 511 are arranged in a matrix shape, with buffer heads provided at both ends, and pressure sensors provided on the buffer heads; through the matrix arrangement and the provision of pressure sensors, the clamping range of the clamping rods 511 is large, and the clamping force is visible and controllable.

[0046] It should be further explained that the positioning member is an electrorheological fluid; the clamping seat 508 is hollow, and a liquid storage cavity filled with electrorheological fluid and through which the clamping rod 511 is sealed and penetrated is arranged inside; when the clamping surface is formed, the electrorheological fluid is energized to change from liquid to solid, so as to fix and seal the clamping rod 511 that penetrates the liquid storage cavity. This clamping method can ensure the clamping fit without causing excessive clamping force, and effectively protect the safety of the artwork.

[0047] like Figure 6 As shown, the exhaust dust collector 6 also includes a base 602 located at the bottom of the exhaust dust collector 601 and a mounting pipe 604 located at the top of the exhaust dust collector 601; the base 602 has a handle 605 and is detachably mounted at the bottom of the support tube 1; the dust inlet end of the pipe 603 is provided with a branch pipe corresponding to the dust collecting tube 503, and the dust collecting end is provided with a main pipe detachably connected to the mounting pipe 604; a negative pressure pump and a filter element are arranged in the exhaust dust collector 601. The dust in the engraving process is collected and filtered through the pipe 603 to reduce dust and odor pollution in the environment.

[0048] Embodiment 2, based on the rotary worktable of the laser engraving machine in Embodiment 1, proposes a laser engraving method, the steps are as follows:

[0049] S1, before engraving, the outer half cover 301 is driven by the motor 303 to rotate to face the notch of the inner half cover 302, and the engraving chamber is opened;

[0051] S3, the artworks to be engraved are placed one by one on the turning plate 501; the cylinder 512 drives the clamping seat 508 to move backward close to the mounting plate 509, and all the clamping rods 511 are all toward the center of the turning plate 501, and the ends of all the clamping rods 511 are on the same horizontal plane; then the cylinder 512 drives the clamping seat 508 to move forward close to the artwork, and all the clamping rods 511 gradually contact the surface of the artwork, and the clamping rods 511 contacting the convex surface stop moving forward, and at the same time the clamping seat 508 slides along the stationary clamping rods 511, so that the clamping rods 511 contacting the concave surface continue to move forward, and finally all the clamping rods 511 are in contact with the surface of the artwork to form a clamping surface consistent with its appearance;

[0052] S4, after the clamping surface is formed, the electrorheological fluid is energized to change from liquid to solid, so as to fix and seal the clamping rod 511 that penetrates the liquid storage cavity;

[0053] S5, the outer half cover 301 rotates to intersect with the notch of the inner half cover 302, and the carving chamber is closed;

[0054] S6, the laser engraver 9 moves forward and backward, the operating panel 2 rotates, and the artwork to be engraved is moved to the bottom of the laser engraver 9 in sequence for laser engraving; during the engraving process, the dust removal cylinder 503 rotates, and the turning plate 501 turns over to further adjust the engraving angle;

[0055] S7, when the flip plate 501 flips, the dust slides along the surface of the flip plate 501 into the dust collecting box 504, and is further cooled, dusted and deodorized when passing through the wind wall;

[0056] S8, the engraved artwork enters the engraving room at the rear, and the detector 8 confirms the engraving effect of the engraved artwork. If any engraving problem is found, it returns to the front of the engraving room and uses the laser engraver 9 to correct it;

[0057] S9. After the carving of multiple groups of artworks is completed in sequence, the outer half cover 301 is rotated to face the notch of the inner half cover 302, and the carving chamber is opened.
