Technical Field
[0001] This utility model relates to the field of decorative stone processing technology, and in particular to a laser positioning device for decorative stone mosaic patterns. Background Technology
[0002] In the field of architectural decoration, decorative stone mosaics, with their unique artistic charm, are widely used in hotel lobbies, villa floors, high-end office buildings, and other places, becoming an important means of enhancing the decorative effect of spaces. As people's aesthetic standards continue to improve, the demand for the precision, complexity, and diversity of decorative stone mosaic patterns is growing, which places extremely high demands on the positioning technology in the stone mosaic processing.
[0003] Traditional methods for positioning stone mosaics have many limitations. In the past, manual measurement and marking were common practices. Workers relied on experience, using tools such as measuring tapes and ink cartridges to measure and mark lines on the stone surface to determine the position and shape of the mosaic pattern. However, this method is highly susceptible to human error. Different workers have varying operating habits and skill levels, resulting in positioning errors often reaching 1-3mm, making it difficult to meet the processing requirements of complex, high-precision mosaic patterns. For example, when processing mosaics with intricate geometric shapes or continuous patterns, manual positioning errors may prevent precise alignment between mosaic components, severely impacting the overall aesthetics.
[0004] While some early mechanical positioning devices improved positioning accuracy to a certain extent, they lacked flexibility. These devices had fixed structures and were typically only suitable for positioning stone mosaics of specific shapes and sizes, making them ill-suited for diverse design needs. Once a new mosaic pattern or change in stone specifications was encountered, the entire positioning device required large-scale modification or even replacement, which was time-consuming, labor-intensive, and costly. For example, traditional mechanical positioning devices were often ineffective in processing stone mosaics with special angles or irregular shapes.
[0005] In the process of stone mosaic, fixing the stone and adjusting its angle also present challenges. Ordinary clamping devices cannot guarantee the stability of the stone during processing, and displacement can easily occur, leading to deviations in the mosaic pattern. Moreover, traditional devices are complex to operate and difficult to control in terms of precision when adjusting the stone's tilt angle, failing to meet the stringent requirements of high-precision processing techniques such as laser engraving. For example, in laser shadow carving, insufficient precision in adjusting the stone's tilt angle will result in poor shadow effects in the engraved pattern, affecting its artistic expression.
[0006] With the widespread application of laser technology in the industrial field, some laser positioning devices have begun to be used in stone processing. However, existing devices still have defects in structural design and functional implementation. Some devices can only perform simple linear positioning and cannot accurately project complex curved patterns. Some devices with pattern projection functions lack effective fixing and flexible angle adjustment mechanisms for the stone during positioning, which makes the stone prone to displacement or tilting due to external forces during actual processing, affecting positioning accuracy and processing quality.
[0007] In summary, existing technologies cannot simultaneously meet the demands for precise positioning, flexible adjustment, and stable clamping in decorative stone mosaic pattern positioning. There is an urgent need for an innovative laser positioning device to improve the efficiency and quality of decorative stone mosaic processing and promote the development of the industry.

Detailed Implementation
[0033] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0034] Reference Figure 1-6 A laser positioning device for decorative stone mosaic patterns includes a support box 1, a tray 2, multiple ball seats 201, multiple universal balls 202, a support ball 21, a motor 22, four positioning clamps 3, a ring seat 4, and a support ring 41.
[0035] The support ball 21 is omnidirectionally mounted on the tray 2 at the center position. The motor 22 is fixedly mounted on the bottom of the support box 1, and the output shaft of the motor 22 is fixedly connected to the support ball 21. The tray 2 has four guide openings arranged radially around the support ball 21. The four positioning clamps 3 are slidably mounted on the top side of the tray 2. The guide rods 32 are fixedly mounted in the four guide openings. The sliders 31 are slidably mounted on the four guide rods 32. The four positioning clamps 3 are fixedly mounted on the top side of the corresponding sliders 31, which can provide support and guidance for the positioning clamps 3.
[0036] An annular seat 4 and a support ring 41 located on the same axis are fixedly installed on the bottom side of the support plate 2. Four ball screws 5 are rotatably installed on the annular seat 4 and the support ring 41, arranged radially around the support ball 21. Each of the four ball screws 5 is threaded with a sleeve that is fixedly connected to the corresponding slider 31. When the ball screws 5 rotate, the slider 31 can be controlled to move the positioning clamp 3 towards or away from the support ball 21, thereby achieving the positioning and clamping effect of the stone. Four worms 52 are rotatably installed on the annular seat 4. The ends of the four ball screws 5 that are close to each other are fixedly fitted with worm wheels 51. The four worms 52 mesh with the corresponding worm wheels 51 respectively. When the worms 52 rotate, the ball screws 5 can be driven to rotate through the worm wheels 51. At the same time, a self-locking effect can be achieved after adjustment, thereby ensuring the positioning accuracy.
[0037] Each of the four worm gears 52 is fixedly fitted with a transmission gear 53. A double-sided gear disc 54 is rotatably mounted on the bottom of the ring seat 4 and on the inner wall of the bottom of the ring seat 4. The two double-sided gear discs 54 mesh with the corresponding two transmission gears 53 respectively. A second motor 55 is fixedly mounted on the inner wall of the bottom of the ring seat 4 and on the bottom of the ring seat 4. A drive gear 56 is fixedly fitted on the output shaft of the two second motors 55. The two drive gears 56 mesh with the corresponding double-sided gear discs 54 respectively, which can provide driving force for the ball screw 5.
[0038] A strip plate 6 is radially fixed on the output shaft of motor 22. A servo cylinder 61 is hinged to both ends of the strip plate 6. The telescopic ends of the two servo cylinders 61 are hinged to the bottom side of the base, which can adjust the tilt angle of the support plate 2 as needed.
[0039] Multiple ball seats 201 are fixedly installed on the top side of the support plate 2, and multiple omnidirectional balls 202 are omnidirectionally installed in the corresponding ball seats 201. The multiple omnidirectional balls 202 are located in the same plane, which can provide stable support for the stone while allowing it to slide freely in the plane.
[0040] In this embodiment, in order to provide stable support for the strip plate 6 and ensure that the strip plate 6 always remains in a horizontal state, multiple support wheels 62 are rotatably installed at both ends of the bottom side of the strip plate 6, and the multiple support wheels 62 are rolled on the bottom inner wall of the support box 1.
[0041] In this embodiment, in order to ensure the accuracy of adjustment, both motor 22 and motor 55 are servo motors.
[0042] In this embodiment, an anti-slip pad is fixedly attached to the side of the positioning clamp 3 near the support ball 21. A pressure sensor that abuts against the positioning clamp 3 is embedded in the anti-slip pad. This can prevent the stone from slipping after being clamped and positioned, and at the same time facilitate the monitoring of the clamping and positioning force to avoid over-clamping or poor clamping stability.
[0043] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.
[0044] Working principle: In use, first turn on the power and place the stone to be processed on the multiple universal balls 202 on the top of the pallet 2. Then, through the free sliding characteristics of the universal balls 202, the position of the stone is initially adjusted so that it is roughly in the center area. Next, start the second motor 55. The output shaft of the second motor 55 drives the drive gear 56 to rotate. The drive gear 56 meshes with the double-sided gear plate 54, causing the double-sided gear plate 54 to drive the two transmission gears 53 meshing with it to rotate. The transmission gears 53 transmit power to the corresponding ball screw 5 through the cooperation of the worm gear 52 and the worm wheel 51. During the rotation of the ball screw 5, the threaded sleeve on it drives the slider 31 to slide along the guide rod 32, thereby driving the positioning clamp 3 to move closer to the stone. Under the action of the four positioning clamps 3, the stone is gradually clamped and positioned in the center of the pallet 2. During this process, the pressure sensor monitors the clamping force in real time to ensure that the stone is firmly clamped and will not be damaged due to over-clamping.
[0045] When the angle of the stone needs to be adjusted, motor 22 is started. The output shaft of motor 22 drives the strip plate 6 and the support ball 21 to rotate synchronously. The rotation of the strip plate 6 causes the pallet 2 and the stone on it to change angle together to meet the processing requirements of different mosaic patterns. If the tilt angle of the pallet 2 needs to be finely adjusted, the servo cylinder 61 is controlled to extend and retract. The extension and retraction end of the servo cylinder 61 is connected by a hinge to push or pull the strip plate 6, thereby changing the tilt angle of the pallet 2.
[0046] Throughout the operation, the support wheel 62 at the bottom of the strip plate 6 rolls on the inner wall of the bottom of the support box 1, providing stable support for the strip plate 6, ensuring the smooth operation of the device, and reducing the impact of mechanical vibration on positioning accuracy.

Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of this utility model.
