Description

Technical Field

[0001] The utility model relates to the field of glass fine carving equipment, in particular to a high-precision glass fine carving machine. Background Art

[0002] There are many types of high-precision glass engraving machines, one of which is the laser glass engraving machine that produces patterns on the glass surface. Usually, this equipment uses a high-energy laser beam to irradiate the glass surface, causing the glass material to quickly melt, vaporize or reach the ignition point, and at the same time blows away the molten or burning material with a high-speed airflow, thereby achieving the purpose of engraving patterns.

[0003] When existing high-precision glass engraving machines are engraving on the outer surface of glass, due to the interaction between the laser and the glass material during the processing, they will produce high-brightness light. These high-brightness lights are mainly caused by the reflection and scattering of the laser beam and the melting and vaporization of the glass material during the processing. These high-brightness lights can cause damage to the retina and even lead to permanent vision loss or blindness. Even if it is not directly irradiated, long-term exposure to high-brightness light can cause fatigue and discomfort to the eyes. Moreover, high-brightness light can interfere with the operator's vision and reduce the comfort and safety of the working environment. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a high-precision glass engraving machine to solve the technical problem that the traditional high-precision glass engraving machine has potential safety hazards during use.

[0005] To achieve the above object, the utility model provides the following technical solutions: a high-precision glass engraving machine, comprising a machine base and a mounting plate, wherein a laser engraver is detachably connected to the outer surface of the mounting plate, and protective mechanisms are arranged on both sides of the laser engraver, wherein the protective mechanisms include a fixing plate, wherein a fixing hole is provided on the outer surface of the fixing plate, and a fixing bolt is connected to the inner thread of the fixing hole, and the fixing plate is detachably connected to the mounting plate through the fixing bolt;

[0006] Two fixing plates are provided, a first protective plate is provided between the two fixing plates, a first card is provided on the inner side of the first protective plate, a second card is provided above the first card, the first card is used to clamp the second card, a second protective plate is provided on the inner side of the second card, and the second protective plate can be slidably connected on the inner side of the first protective plate.

[0007] By adopting the above technical solution, the second protective sheet can be slidably connected to the inner side of the first protective sheet through the design of the first card clamping the second card. This design provides flexibility in the protection range, allowing the operator to easily adjust the position and coverage area of ​​the protective sheet according to the engraving requirements or the working status of the laser engraver. This adjustability not only optimizes the safety protection effect, but also improves the adaptability of the equipment to different processing scenarios.

[0008] Furthermore, a counterweight block is provided at the bottom of the second protective sheet, and the counterweight block is used to ensure the stability of the second protective sheet when sliding on the glass.

[0009] By adopting the above technical solution, the counterweight block effectively enhances the stability of the second protective sheet when it slides on the glass by increasing the bottom weight of the second protective sheet. This design can reduce the movement or offset of the protective sheet caused by external interference such as airflow and vibration, thereby ensuring the consistency and reliability of the protective effect. This stability is particularly important in scenarios such as high-speed engraving or long-term continuous work, as it can prevent accidental leakage of the laser and protect the safety of the operator and equipment.

[0010] Furthermore, the first protective sheet and the second protective sheet are made of black glass plates, and are used to block laser highlights.

[0011] By adopting the above technical solution, the ink-colored glass plate has good light-shielding properties and can effectively absorb and block the high-intensity light generated during the laser engraving process. The choice of this material ensures that the protective sheet can provide sufficient protection during the laser engraving operation to prevent the high-brightness laser light from directly shining on the operator or the surrounding environment, thereby reducing safety risks.

[0012] Furthermore, first mounting frames are provided at both the front and rear ends of the machine base, the inner sides of the two first mounting frames are detachably connected with first linear motors, a moving platform is provided at the moving end of the first linear motor, and a negative pressure mechanism is provided on the top of the moving platform.

[0013] By adopting the above technical solution, the machine base serves as the basic supporting structure of the entire equipment, ensuring the stability and durability of the equipment. By arranging the first mounting frame at the front and rear ends of the machine base, a solid and accurate installation position is provided for the first linear motor. This layout not only ensures the stability and accuracy of the first linear motor during operation, but also enables the movable table to move along a precise trajectory, thereby improving the processing accuracy and consistency of glass carving.

[0014] Furthermore, the negative pressure mechanism includes a connecting port, which is used to connect an exhaust pipe, and an exhaust device is provided at the other end of the exhaust pipe.

[0015] By adopting the above technical solution, the vacuum pipe connected to the pipe port and the vacuum equipment work together to quickly form a negative pressure environment on the moving table. This negative pressure adsorption force can effectively fix the glass workpiece to ensure that it will not move or warp during the processing. This efficient fixing method not only improves the processing accuracy, but also shortens the preparation time and improves the overall processing efficiency.

[0016] Furthermore, a plurality of negative pressure suction cups are arranged on the top of the movable platform, and the plurality of negative pressure suction cups are arranged in a rectangular array. Air suction ports are opened inside the plurality of negative pressure suction cups, and the air suction ports are all connected with the connecting pipe ports.

[0017] By adopting the above technical solution, multiple negative pressure suction cups are arranged in a rectangular array, ensuring that the glass workpiece is subjected to uniform and stable adsorption force during the processing. This layout avoids the warping or deformation of the workpiece that may be caused by single-point adsorption, thereby improving the processing accuracy and product quality. At the same time, the evenly distributed adsorption force also helps to reduce the vibration and displacement of the workpiece during the processing, further improving the stability of the processing.

[0018] Furthermore, the negative pressure suction cup is made of rubber, and is used to absorb the glass to be processed.

[0019] By adopting the above technical solution, the rubber material has good elasticity and sealing properties, so that the negative pressure suction cup can form a tight fit when in contact with the glass surface, thereby effectively creating a negative pressure environment. This tight fit ensures the uniform distribution and continuous stability of the adsorption force, avoids the movement or falling of the glass during the processing, and improves the safety and precision of the processing.

[0020] Furthermore, second mounting frames are arranged on both sides of the machine base, and a second linear motor is arranged on the inner side of the second mounting frame.

[0021] By adopting the above technical solution, by arranging a second mounting frame on both sides of the machine base and installing a second linear motor, additional degrees of freedom of movement can be provided for the glass engraving machine. This design enables the processing head or related components to move precisely on an axis perpendicular to the movement direction of the moving table, thereby achieving a more complex processing trajectory and higher processing accuracy.

[0022] Furthermore, a lead screw motor is installed at the moving end of the second linear motor, and a mounting plate is provided at the output end of the lead screw motor.

[0023] By adopting the above technical solution, the lead screw motor can achieve high-precision linear motion through its unique lead screw transmission mechanism. When it is combined with the second linear motor, it can ensure the precise positioning of the mounting plate in three-dimensional space. This precise position control is crucial for glass precision carving because it can ensure that the laser engraver or other processing tools accurately act on the predetermined position of the glass, thereby improving the processing accuracy and quality of the product.

[0024] Furthermore, the laser engraver, the first linear motor, the second linear motor and the lead screw motor are all electrically connected to an external controller.

[0025] By adopting the above technical solution, by electrically connecting all key components to an external controller, the operator can monitor and adjust the working status of the laser engraver and the motion parameters of the first linear motor, the second linear motor and the lead screw motor through a single control interface or system. This centralized control method simplifies the operation process, improves work efficiency, and reduces the risk of misoperation caused by decentralized control.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] 1. The utility model sets a protective mechanism, wherein the protective mechanism includes fixed plates, which have fixing holes. The fixed plates can be detachably connected to the mounting plate by fixing bolts, which provides convenient installation and disassembly functions. A first protective plate is set between the two fixed plates. This is a static protective plate, and its position is fixed. The second protective plate is designed to slide inside the first protective plate. Therefore, the operator can adjust the position of the protective plate according to the position of the engraving head to ensure that the normal operation of the engraving head is not hindered while providing necessary protection. At the same time, a counterweight block is set at the bottom of the second protective plate. The function of this counterweight block is to ensure the stability of the second protective plate during the sliding process. In addition, the first protective plate and the second protective plate are both made of ink-colored glass plates, which can effectively absorb and block the high light generated during laser engraving, and protect the operator's eyesight and the safety of the surrounding environment.

[0028] 2. The utility model provides a negative pressure mechanism, wherein the negative pressure mechanism forms a stable adsorption force on the top of the movable platform through a plurality of negative pressure suction cups, thereby ensuring that the glass to be processed will not move or shake during the engraving process. Such stability is essential for ensuring the engraving accuracy, and a plurality of negative pressure suction cups are arranged in a rectangular array, so that the adsorption force is evenly distributed on the glass surface, thereby avoiding deformation or breakage of the glass that may be caused by single-point adsorption. In addition, the connecting port is connected to the exhaust pipe and the exhaust equipment, thereby ensuring that negative pressure can be quickly formed inside the negative pressure suction cup, thereby improving the adsorption speed and efficiency.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] Embodiment 1:

[0037] A high-precision glass engraving machine, such as Figure 1-Figure 4As shown, it includes a machine base 1 and a mounting plate 10. The outer surface of the mounting plate 10 is detachably connected to a laser engraver 11. Both sides of the laser engraver 11 are provided with protective mechanisms 8. The protective mechanisms 8 include a fixing plate 801. The outer surface of the fixing plate 801 is provided with a fixing hole 802. The internal thread of the fixing hole 802 is connected with a fixing bolt, and the fixing plate 801 is detachably connected to the mounting plate 10 through the fixing bolt. Two fixing plates 801 are provided. A first protective plate 803 is provided between the two fixing plates 801. A first card 804 is provided on the inner side of the first protective plate 803. A second card 806 is provided above the first card 804. Card 804 is used to clamp the second card 806. A second protective sheet 805 is provided on the inner side of the second card 806. The second protective sheet 805 can be slidably connected to the inner side of the first protective sheet 803. The fixing sheet 801 is detachably connected to the mounting plate 10 by fixing bolts, which means that the installation and disassembly process of the protective mechanism 8 is simple and quick. When maintenance or replacement of the protective sheet is required, the operator can quickly remove the fixing bolts and remove the protective mechanism 8 to perform necessary operations. This design not only reduces maintenance time, but also reduces maintenance costs, while improving the operator's work efficiency. In addition, the detachable connection design also facilitates the transportation and storage of the equipment.

[0038] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A counterweight block 807 is provided at the bottom of the second protective sheet 805. The counterweight block 807 is used to ensure the stability of the second protective sheet 805 when it slides on the glass. Since the counterweight block 807 ensures the smooth movement of the second protective sheet 805, this also helps to improve the working accuracy of the glass engraving machine. During the engraving process, the stable position of the protective sheet can reduce the error caused by the movement of the protective sheet, ensuring that the laser engraver 11 can accurately act on the predetermined position. This improvement in accuracy not only improves product quality, but also reduces material waste and the need for subsequent processing, further improving production efficiency and cost-effectiveness.

[0039] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The first protective sheet 803 and the second protective sheet 805 are made of ink-colored glass plates. The first protective sheet 803 and the second protective sheet 805 are used to block laser highlights. Although the ink-colored glass plates can block laser highlights, they still have a certain degree of transparency. This means that when the operator observes the engraving process through the protective sheets, he can maintain a relatively clear field of vision without causing too much interference to the operation. This design is particularly important when it is necessary to monitor the engraving progress in real time or adjust equipment parameters, which helps to improve work efficiency and operation accuracy.

[0040] Embodiment 2:

[0041] See also Figure 1 , Figure 2 , Figure 3 A first mounting frame 2 is provided at both the front and rear ends of the machine base 1, and a first linear motor 3 is detachably connected to the inner side of the two first mounting frames 2. A moving table 4 is provided at the moving end of the first linear motor 3, and a negative pressure mechanism 5 is provided on the top of the moving table 4. The design of the negative pressure mechanism 5 on the top of the moving table 4 enables the glass workpiece to be quickly and firmly fixed on the moving table, avoiding shaking or displacement during the processing. At the same time, the first linear motor 3 drives the moving table 4 to move efficiently and accurately along a straight line trajectory, which greatly improves the processing efficiency and finished product quality of glass carving. This design is particularly suitable for large-scale and high-precision glass processing needs.

[0042] See also Figure 1 , Figure 2 , Figure 3 The negative pressure mechanism 5 includes a pipe connection port 501, which is used to connect the exhaust pipe, and an exhaust device is provided at the other end of the exhaust pipe. The design of the pipe connection port 501 is standardized, and it can be conveniently connected to different types of exhaust devices. This design makes the negative pressure mechanism 5 have good flexibility and expansibility. Different exhaust devices and parameter settings can be selected according to different processing requirements to achieve the best processing effect. In addition, the standardized design also helps to reduce maintenance costs and facilitate replacement of parts.

[0043] See also Figure 1 , Figure 2 , Figure 3 A plurality of negative pressure suction cups 502 are arranged on the top of the movable platform 4, and the plurality of negative pressure suction cups 502 are arranged in a rectangular array. Air suction ports 503 are opened inside the plurality of negative pressure suction cups 502, and the air suction ports 503 are all connected with the connecting ports 501. Through the connecting design of the air suction ports 503 and the connecting ports 501, the negative pressure suction cups 502 can quickly form a negative pressure environment to achieve rapid fixation of the glass workpiece. This fixing method is not only easy to operate and efficient, but also suitable for glass workpieces of different sizes and shapes. In addition, since the negative pressure suction cups 502 are detachable, the number and layout of the suction cups can be flexibly adjusted according to specific processing requirements to meet processing requirements in different scenarios.

[0044] See also Figure 1 , Figure 2 , Figure 3The negative pressure suction cup 502 is made of rubber. The negative pressure suction cup 502 is used to absorb the glass to be processed. Rubber is a soft material with a certain friction. It can reduce scratches or damage to the glass surface when absorbing the glass. Compared with hard materials, the rubber negative pressure suction cup 502 is gentler when fixing and moving the glass, which helps to protect the smoothness and overall quality of the glass, which is particularly important for glass processing that requires high precision and high surface quality.

[0045] See also Figure 1 , Figure 2 , Figure 3 A second mounting frame 6 is arranged on both sides of the machine base 1, and a second linear motor 7 is arranged on the inner side of the second mounting frame 6. The existence of the second linear motor 7 expands the functionality and flexibility of the glass engraving machine. It can cooperate with the moving table 4 and the first linear motor 3 to realize a variety of complex processing operations, such as beveling, curve cutting, multi-dimensional engraving, etc. This design enables the glass engraving machine to adapt to a wider range of processing needs, improves the overall utilization rate of the equipment and the return on investment, and at the same time, for situations where special processing tasks need to be performed, the second linear motor 7 also provides the necessary hardware support.

[0046] See also Figure 1 , Figure 2 , Figure 3 A screw motor 9 is installed at the moving end of the second linear motor 7, and a mounting plate 10 is provided at the output end of the screw motor 9. The mounting plate 10, as the output end of the screw motor 9, provides a stable and adjustable platform for the installation of equipment such as a laser engraver 11. By adjusting the position and angle of the mounting plate 10, the spatial posture of the processing tool can be easily adjusted to meet different processing requirements. This design not only simplifies the installation and adjustment process of the equipment, but also improves the adaptability and flexibility of the equipment, so that it can better cope with various complex glass processing tasks.

[0047] See also Figure 1 , Figure 2 , Figure 3 The laser engraver 11, the first linear motor 3, the second linear motor 7 and the lead screw motor 9 are all electrically connected to the external controller. The external controller can accurately control the power, frequency and engraving path of the laser engraver 11, and coordinately adjust the movement speed and position of the first linear motor 3, the second linear motor 7 and the lead screw motor 9 to ensure the precise coordination of each component during the processing. This coordinated control not only improves the processing accuracy and consistency of glass carving, but also enables the equipment to perform more complex processing tasks to meet diversified product needs.

[0048] The implementation principle of the utility model is as follows: first, place the glass plate to be processed on the moving table 4, ensure that the glass plate is flat and fully in contact with the negative pressure suction cup 502, then start the negative pressure mechanism 5, connect the suction device through the pipe port 501, so that negative pressure is formed inside the negative pressure suction cup 502, so as to firmly adsorb the glass plate;

[0049] Subsequently, the operator sets the processing parameters of the laser engraver 11, such as laser power, engraving speed, engraving depth, etc., through the external controller to ensure that specific processing requirements are met, and adjusts the motion parameters of the first linear motor 3 and the second linear motor 7 as needed to determine the processing range and moving path of the glass plate;

[0050] During the processing, the first protective sheet 803 and the second protective sheet 805 can effectively block the laser highlights and protect the operator's eyes from being hurt.
