Description

Equipment for intangible cultural heritage shell carving art Technical Field

[0001] This application relates to the field of laser engraving technology, for example to a device for intangible cultural heritage shell carving art. Background Technology

[0002] Shell carving, an intangible cultural heritage, is a unique treasure of traditional Chinese arts and crafts, imbued with a maritime spirit. Its development is deeply marked by maritime trade and the fusion of civilizations, with "Beihai Shell Carving," which was included in the fifth batch of national intangible cultural heritage representative projects in 2021, being a prime example. Laser engraving equipment, a new type of processing tool developed based on laser technology, has become an important bridge connecting traditional crafts with modern technology.

[0003] Among related technologies, laser engraving equipment is used to process seashells at a much faster speed than hand-carving, significantly reducing the production cycle for complex patterns. Furthermore, laser engraving causes less material deformation to the seashells, better preserving their natural shape and thus providing more avenues for the inheritance and innovation of intangible cultural heritage techniques.

[0004] In implementing the embodiments of this disclosure, at least the following problems were found in the related technology: Shells come in a wide variety of types, such as thin shells, thick shells, and brittle shells, and their textures are generally uneven. When a laser is applied to the surface of a shell, its organic components are prone to carbonization, easily resulting in black marks remaining at the engraving point. This not only damages the shell's natural color and warm texture but also seriously affects the overall aesthetics of the work.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

As shown in FIG3, the bottom wall interlayer of the clamping groove 210 is provided with independent first space 211 and second space 212, and the second space 212 is arranged around the first space 211. The side wall interlayer of the clamping groove 210 is provided with a third space 213. The first space 211 is provided with a first air intake 2111, and the lower end of the support tube 220 is connected to the first air intake 2111. The second space 212 is provided with a plurality of second air intakes 2121 arranged around the first air intake 2111, and the second air intakes 2121 are connected to the groove of the clamping groove 210. The third space 213 is provided with a water inlet 2131, which is connected to the groove of the fixture slot 210. A laser device 300 is movably mounted above the worktable 100. The laser device 300 includes a laser slot 310 and an emitter 320. The opening of the laser slot 310 faces downwards toward the fixture slot 210, and the emitter 320 is located within the laser slot 310. A fourth space 311 is provided within the interlayer of the laser slot 310, and the fourth space 311 has multiple air blowing ports 3111. As shown in Figure 4, the air circulation system 400 includes a first air pipe 410, a second air pipe 420, a third air pipe 430, an inert gas tank 440, and an air pump 450. The first air pipe 410 is connected at both ends to the first space 211 and the inlet of the air pump 450, respectively. The second air pipe 420 is connected at both ends to the second space 212 and the inlet of the air pump 450, respectively. The third air pipe 430 is connected at both ends to the fourth space 311 and the outlet of the air pump 450, respectively. The outlet of the inert gas tank 440 is connected to the inlet of the air pump 450. As shown in Figure 6, the water circulation system 500 includes a first water pipe 510, a second water pipe 520, a third water pipe 530, a solution tank 540, and a water pump 550. The first water pipe 510 is connected at both ends to the second space 212 and the inlet of the water pump 550, respectively. The second water pipe 520 is connected at both ends to the third space 213 and the outlet of the water pump 550, respectively. The third water pipe 530 is connected at both ends to the outlet of the water pump 550 and the external environment, respectively. The outlet of the solution tank 540 is connected to the inlet of the water pump 550. The switching device 600 is used to control the opening and closing of the second air intake 2121. It should be noted that the multiple pipelines included in the air circulation system 400 and water circulation system 500 are arranged according to different types of workbenches 100, and are not limited here.

[0023] In this embodiment, the clamping groove 210 is used to place the shell to be carved, and the support tube 220 is used to support the suction cup 230, which is used to adsorb the non-carving area of ​​the shell. The laser groove 310 is used to house the emitter 320, which is used to emit laser light for carving. The gas circulation system 400 is used to supply inert gas into the clamping groove 210. The inert gas has an antioxidant effect, and the circulation of the inert gas helps to reduce the temperature of the laser focal point, thereby inhibiting the carbonization reaction of the shell. The water circulation system 500 is used to inject a solution for dissolving carbides into the clamping groove 210, thereby cleaning the carbonized black edges that have already occurred. In this way, the problem of residual carbonized black edges on the shell is solved from the perspectives of inhibiting the carbonization reaction and dissolving carbides, respectively, during and after carving.

[0024] Optionally, a first air control valve is provided on the first air pipe 410, which is used to control the opening and closing of the first air pipe 410.

[0025] Optionally, a second air control valve is provided on the second air pipe 420, which is used to control the opening and closing of the second air pipe 420.

[0026] Optionally, a third air control valve is provided on the third air pipe 430, which is used to control the opening and closing of the third air pipe 430.

[0027] Optionally, a first water control valve is provided on the first water pipe 510, which is used to control the opening and closing of the first water pipe 510.

[0028] Optionally, a second water control valve is provided on the second water pipe 520, which is used to control the opening and closing of the second water pipe 520.

[0029] Optionally, a third water control valve is provided on the third water pipe 530, which is used to control the opening and closing of the third water pipe 530.

[0030] Optionally, the equipment includes an engraving mode, which corresponds to: the air circulation system 400 being activated and the water circulation system 500 being deactivated; the first air pipe 410 being open; the second air pipe 420 being open; the third air pipe 430 being open; the inert gas tank 440 being opened; and the second air intake 2121 being opened, so that inert gas is blown from the air outlet 3111 into the fixture slot 210, and then enters the second space 212 from the second air intake 2121 for recirculation. The airflow circulation is shown in Figure 4.

[0031] In this embodiment, with the first air tube 410 open, a negative pressure is formed within the suction cup 230, effectively securing the shell. Inert gas stored in the inert gas tank 440 enters the third space 213 and is blown from the air outlet 3111 into the clamping groove 210 below. With the second air inlet 2121 open, the gas in the clamping groove 210 enters the second space 212 from the second air inlet 2121, and then flows along the second air tube 420 to the inlet of the air pump 450 for reuse, thus continuously supplying inert gas to the clamping groove 210. Furthermore, the concentration of inert gas can be adjusted by regulating the opening of the inert gas tank 440.

[0032] Optionally, the equipment includes a cleaning mode, which includes a water injection stage and a drainage stage. As shown in Figure 5, the water injection stage corresponds to: the air circulation system 400 being deactivated and the water circulation system 500 being activated, wherein the water pump 550 is turned on, the first water pipe 510 is blocked, the second water pipe 520 is open, the solution tank 540 is opened, and the second air intake 2121 is closed, so that the solution flows into the fixture groove 210 from the water injection port 2131. As shown in Figure 6, the drainage stage corresponds to: the air circulation system 400 being deactivated and the water circulation system 500 being activated, wherein the water pump 550 is turned on, the first water pipe 510 is open, the second water pipe 520 is blocked, the third water pipe 530 is open, the solution tank 540 is closed, and the second air intake 2121 is opened, so that the solution enters the second space 212 from the second air intake 2121 and then is discharged from the third water pipe 530.

[0033] In this embodiment, with the air circulation system 400 disabled, the suction cup 230 supports the shell, and as the water level in the clamping groove 210 gradually rises, the shell floats or sinks without damage due to the buffering effect of the liquid. Here, the cleaning process first involves a water injection stage followed by a drainage stage. During the water injection stage, the solution stored in the solution tank 540 enters the third space 213 through the second water pipe 520 and then enters the clamping groove 210 through the water injection port 2131. Since the second air intake port 2121 is closed, the water level in the clamping groove 210 gradually rises until it covers the shell. During the drainage stage, since the second air intake port 2121 is open, the solution flows into the second space 212 through the second air intake port 2121 and is discharged to the external environment through the first water pipe 510 and the third water pipe 530 in sequence.

[0034] Optionally, as shown in Figure 7, the switching device 600 includes a turntable 610, a rotating shaft 620, and a motor 630. The surface of the turntable 610 is provided with multiple switching holes 611 corresponding to the second air intake 2121. The turntable 610 is mounted against the bottom wall of the clamping groove 210. The first end of the rotating shaft 620 is connected to the rotation center of the turntable 610. The drive shaft 631 of the motor 630 is connected to the second end of the rotating shaft 620, thereby driving the turntable 610 to rotate via the rotating shaft 620. The turntable 610 has a first rotation position and a second rotation position. The first rotation position corresponds to the switching holes 611 being connected to the second air intake 2121, while the second rotation position corresponds to the switching holes 611 being misaligned and blocked from the second air intake 2121.

[0035] In this embodiment, the motor 630 drives the turntable 610 to rotate via the rotating shaft 620. When the turntable 610 is in the first rotation position, the second air intake 2121 is open, and the clamping groove 210 is connected to the second space 212. When the turntable 610 is in the second rotation position, the second air intake 2121 is blocked by the turntable 610, and the clamping groove 210 and the second space 212 are independent of each other. In this way, the opening and closing state of the second air intake 2121 can be controlled by the motor 630.

[0036] Optionally, the second space 212 is provided with a first connecting port 2122, and the third space 213 is provided with a second connecting port 2132. The first connecting port 2122 and the second connecting port 2132 are respectively located on both sides of the clamping groove 210. The first end of the first water pipe 510 is provided with a first slider interface 511, which is movably configured, and when moved to the docking position, the first water pipe 510 is connected to the first connecting port 2122. The first end of the second water pipe 520 is provided with a second slider interface 521, which is movably configured, and when moved to the docking position, the second water pipe 520 is connected to the second connecting port 2132.

[0037] In this embodiment, when the first slider interface 511 is in the docking position, the solution in the second space 212 can be discharged through the first water pipe 510. When the first slider interface 511 is in the non-docking position, the solution cannot be discharged. When the second slider interface 521 is in the docking position, the solution can be introduced into the third space 213 through the second water pipe 520. When the second slider interface 521 is in the non-docking position, the solution cannot be introduced into the third space 213 through the second water pipe 520.

[0038] Optionally, as shown in Figures 7 and 8, the device further includes a linkage device 700. The first side of the linkage device 700 is connected to the first slider interface 511, the second side is connected to the second slider interface 521, and the middle part of the linkage device 700 is connected to the drive shaft 631 of the motor 630. The linkage device 700 has a first linkage state and a second linkage state. The first linkage state corresponds to: when the turntable 610 is in the first rotation position, the linkage device 700 drives the first slider interface 511 to the docking position and the second slider interface 521 to the non-docking position. The second linkage state corresponds to: when the turntable 610 is in the second rotation position, the linkage device 700 drives the first slider interface 511 to the non-docking position and the second slider interface 521 to the docking position.

[0039] In this embodiment, the turntable 610, the first slider interface 511, and the second slider interface 521 are linked together by the linkage device 700. When solution needs to be discharged, the linkage device 700 is driven to the first linkage state by the motor 630. At this time, the second air intake 2121 is opened, and the solution enters the second space 212 through the second air intake 2121, and then is discharged sequentially through the first water pipe 510 and the third water pipe 530. When solution needs to be stored, the linkage device 700 is driven to the second linkage state by the motor 630. At this time, the second air intake 2121 is closed, and the first slider interface 511 is also closed, with double closure to prevent solution discharge. In addition, solution is continuously injected into the fixture groove 210 through the second water pipe 520. Here, during the engraving process, the linkage device 700 is also in the first linkage state, and closing the first water control valve can prevent gas from flowing to the third water pipe 530.

[0040] Optionally, the linkage device 700 includes a first linkage part 710 and a second linkage part 720. The first linkage part 710 includes a first link assembly 711, a first gear and rack assembly 712, and a second link assembly 713. The first link assembly 711 includes a first rod and a second rod, the first gear and rack assembly 712 includes a first gear condition, a first gear, and a first guide member, and the second link assembly 713 includes a third rod and a fourth rod. The first end of the first rod is connected to a first side of the drive shaft 631, the second end of the first rod is hinged to the first end of the second rod, the second end of the second rod is hinged to the first gear condition, and the first gear condition meshes with the first gear. A first mounting post is provided on the eccentric side of the first gear, the first end of the third rod is hinged to the mounting post, the second end of the third rod is hinged to the first end of the fourth rod, and the second end of the fourth rod is hinged to the first slider interface 511. The second linkage part 720 includes a third link assembly 721, a second gear and rack assembly 722, and a fourth link assembly 723. The third linkage assembly 721 includes a fifth and a sixth linkage; the second gear and rack assembly 722 includes a second gear condition, a second gear, and a second guide; and the fourth linkage assembly 723 includes a seventh and an eighth linkage. The first end of the fifth linkage is connected to the second side of the drive shaft 631, the second end of the fifth linkage is hinged to the first end of the sixth linkage, and the second end of the sixth linkage is hinged to the second gear condition. The second gear condition meshes with the second gear. A second mounting post is provided on the eccentric side of the second gear. The first end of the seventh linkage is hinged to the second mounting post, the second end of the seventh linkage is hinged to the first end of the eighth linkage, and the second end of the eighth linkage is hinged to the second slider interface 521. The eccentric side of the first and second gears refers to the non-central position. Both the first slider interface 511 and the second slider interface 521 move along the guide structure.

[0041] In this embodiment, through the ingenious structural design of the linkage device 700, a multi-stage motion transition is achieved, sequentially from the rotational motion of the drive shaft 631, the planar motion of the first link assembly 711, the linear motion of the first gear, the rotational motion of the first gear, the planar motion of the second link assembly 713, to the linear motion of the first slider interface 511. Simultaneously, a multi-stage motion transition is also achieved, sequentially from the rotational motion of the drive shaft 631, the planar motion of the third link assembly 721, the linear motion of the second gear, the rotational motion of the second gear, the planar motion of the fourth link assembly 723, to the linear motion of the second slider interface 521.

[0042] Optionally, when the drive shaft 631 of the motor 630 rotates forward by a first angle, it drives the turntable 610 to a first rotation position and the linkage device 700 to a first linkage state. When the drive shaft 631 of the motor 630 rotates backward by a first angle, it drives the turntable 610 to a second rotation position and the linkage device 700 to a second linkage state.

[0043] In this embodiment, when the drive shaft 631 of the motor 630 rotates in the forward direction, the first gear condition moves along the first guide member towards the drive shaft 631 via the first linkage assembly 711. The movement of the first gear condition drives the first gear component to rotate, and the rotation of the first gear component drives the first slider interface 511 to move to the docking position via the second linkage assembly 713. Simultaneously, the second gear condition moves along the second guide member towards the drive shaft 631 via the third linkage assembly 721. The movement of the second gear condition drives the second gear component to rotate, and the rotation of the second gear component drives the second slider interface 521 to move to the non-docking position via the fourth linkage assembly 723. It can be understood that when the drive shaft 631 of the motor 630 rotates in the reverse direction, the movement process of the linkage device 700 is reversed.
