[0002] Laser engraving is a technique that uses a high-energy laser beam to precisely process the surface or interior of a material. Through the thermal, photochemical, or mechanical effects of the laser, permanent patterns, text, textures, or outlines are formed on the material. It is widely used in industrial manufacturing, artistic creation, and anti-counterfeiting labeling.

[0003] Existing technologies, such as the utility model patent with publication number CN206084146U, disclose a laser engraving machine, relating to the field of engraving technology. This laser engraving machine includes a motion mechanism, a motor drive device electrically connected to the motion mechanism for driving the motion mechanism, a laser engraving component mounted on the motion mechanism, a control box for housing the motion mechanism, and a fixing plate mounted inside the control box for fixing the processing material. The motion mechanism specifically includes: a transverse slide rail for supporting the left-right sliding of the laser engraving component; a longitudinal slide rail for supporting the up-down sliding of the laser engraving component; and a forward sliding rail for supporting the back-and-forth sliding of the laser engraving component. The laser engraving machine provided by this utility model controls the motion mechanism to move in multiple directions via a control plate and fixes the processing material inside the control box, avoiding the defect of unstable clamping of the processing material as it moves with the motion mechanism. It offers high precision, facilitates fine engraving work, and ensures consistent appearance of the finished product.

[0004] Regarding the above-mentioned issues, the following technical defects were found: During the operation of the plate engraving machine, due to the lack of positioning and clamping devices in general plate engraving machines, when engraving plates of different specifications, the plates are prone to shifting and shaking during the engraving process, which leads to a decrease in the engraving accuracy and product qualification rate. Utility Model Content

A fixed block is rotatably connected to the side of the two connecting rods that are close to each other. A pressure plate is fixedly connected to the lower surface of the fixed block.

[0007] The effect achieved by the above components is as follows: the clamping device set on the upper surface of the machine body can be used to fix plates of different lengths, which helps to prevent the plates from shifting during the engraving process, thereby ensuring the stability of the plates during engraving and improving the qualification rate of the engraved plates.

[0008] Preferably, an anti-slip pad, which is a rubber pad, is fixedly connected to the lower surface of the pressure plate.

[0009] The aforementioned components achieve the following effects: by using anti-slip pads and auxiliary pressure plates to fix the printing plate on the upper surface of the machine body, the pressure plates are prevented from damaging the printing plate and the friction between the pressure plates and the printing plate is increased, thereby improving the fixing effect.

[0010] Preferably, the inner wall of the support plate is provided with a plurality of sliding grooves, and a sliding plate is slidably connected to the inner wall of the sliding grooves. The long arm end of the sliding plate is fixedly connected to the upper surface of the pressure plate.

[0011] The effect achieved by the above-mentioned components is to guide the downward movement of the pressure plate and prevent the pressure plate from shaking when moving downward.

[0012] Preferably, a driven bevel gear is fixedly connected to one end of the double-grooved screw, a motor is fixedly connected to one side of the machine body, and a driving bevel gear is fixedly connected to the output end of the motor, wherein the driving bevel gear meshes with the driven bevel gear.

[0013] The effect achieved by the above components is that the double-threaded screw can be rotated quickly, which is beneficial for the rapid movement of the support plate and makes it easy to fix the plate to the upper surface of the machine body.

[0014] Preferably, one of the support plates is provided with a cleaning device on one side. The cleaning device includes two sliding grooves, which are opened on one side of the support plate. A movable plate is slidably connected to the inner wall of the sliding groove. Two welding plates are fixedly connected to the lower surface of the movable plate.

An electric push rod is fixedly connected to one side of the support plate. The output end of the electric push rod is fixedly connected to the upper surface of the movable plate.

[0015] The effect achieved by the above components is as follows: the cleaning device set on one side of the moving plate cleans the plate material placed on the upper surface of the machine body, avoids the interference of impurities on the upper surface of the plate material with the laser engraving machine, ensures the engraving accuracy, improves the processing stability, and reduces the rework rate.

[0016] Preferably, a fixing plate is fixedly connected to one side of the movable plate, and a blade is fixedly connected to the lower surface of the fixing plate.

[0017] The effect achieved by the above-mentioned component is that it allows for the convenient cutting of a portion of the adhesive paper after use using a blade.

[0018] Preferably, a protective sleeve is slidably connected to one side of the fixing plate, and the length of the protective sleeve is adapted to the length of the blade.

[0019] The effect achieved by the above-mentioned components is to protect the blade, prevent the blade from causing scratches to the operator when not in use, and improve the safety of operation.

[0020] Compared with related technologies, the plate positioning laser engraving machine provided by this utility model has the following advantages:

[0021] Beneficial effects:

[0022] By operating the clamping device, the engraving plate is positioned and fixed. The double-threaded screw drives the two support plates to move, and by rotating the bidirectional screw, the pressure plate moves up and down with the help of the moving block, connecting rod and fixed block. This is beneficial for fixing plates of different sizes and facilitates the engraving of the engraving machine.

[0023] By operating the cleaning device, the surface of the engraving plate is cleaned. The moving plate is pushed by the electric push rod, and the dust-adhesive paper on the arc surface of the rotating shaft is used to clean the surface of the plate when the plate is pushed into the upper surface of the machine body through the end near the dust-adhesive paper. This helps to ensure the engraving accuracy of the plate. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figure 1 The present invention provides a plate positioning laser engraving machine, comprising: linear guide rails 2 fixedly connected to both sides of the machine body 1, a movable seat 3 slidably connected inside the linear guide rails 2, a transverse guide rail 4 installed on the upper surface of the movable seat 3, two bellows covers 9 fitted on the side of the transverse guide rails 4, a laser engraving head 5 installed on the side of the two bellows covers 9 that are close to each other, a control box 6 installed on one side of the machine body 1, a clamping device 7 provided on the upper surface of the machine body 1, and a cleaning device 8 provided on one side of one of the support plates 702.

[0033] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The clamping device 7 includes two slide rails 701. The lower surface of the slide rails 701 is fixedly connected to the upper surface of the machine body 1. Two support plates 702 are slidably connected inside the slide rails 701. The support plates 702 are U-shaped. A double-threaded screw 703 is rotatably inserted through the inner wall of one of the slide rails 701. The arc surfaces at both ends of the double-threaded screw 703 are threaded with opposite threads. The arc surfaces of the double-threaded screw 703 are threadedly connected to the support plate 702. A bidirectional screw 704 is rotatably inserted through the inner wall of the support plate 702. The arc surfaces at both ends of the bidirectional screw 704 are threaded with opposite threads. Two moving blocks 705 are threadedly connected to the arc surfaces of the bidirectional screw 704. Connecting rods 706 are rotatably connected to both sides of the moving blocks 705. A fixed block 707 is rotatably connected to the side of the two connecting rods 706 that are close to each other. A pressure plate 708 is fixedly connected to the lower surface of the fixed block 707. The clamping device 7, located on the upper surface of the machine body 1, can accommodate plates of varying lengths, preventing displacement during engraving and ensuring stability, thus improving the yield rate of finished engraved products. An anti-slip pad 709, made of rubber, is fixedly connected to the lower surface of the pressure plate 708. This pad assists the pressure plate 708 in fixing the plate to the upper surface of the machine body 1, preventing damage and increasing friction between the pressure plate 708 and the plate, thereby enhancing the fixing effect. Several grooves 710 are formed on the inner wall of the support plate 702. A sliding plate 711 is slidably connected to the inner wall of each groove 710, with its long arm fixedly connected to the upper surface of the pressure plate 708. This guides the downward movement of the pressure plate 708, preventing it from wobbling. One end of the double-grooved screw 703 is fixedly connected to a driven bevel gear 712, and a motor 714 is fixedly connected to one side of the machine body 1. The output end of the motor 714 is fixedly connected to a driving bevel gear 713, which meshes with the driven bevel gear 712. This allows the double-grooved screw 703 to rotate quickly, which facilitates the rapid movement of the support plate 702 and makes it easier to fix the printing plate to the upper surface of the machine body 1.

[0034] In the embodiments of this utility model, please refer to Figure 4 and Figure 5The cleaning device 8 includes two sliding grooves 81, which are located on one side of the support plate 702. A movable plate 82 is slidably connected to the inner wall of the sliding groove 81. Two welding plates 83 are fixedly connected to the lower surface of the movable plate 82. A rotating shaft 84 is rotatably connected to the side of the two welding plates 83 that is close to each other. Adhesive paper 85 is fitted onto the arc surface of the rotating shaft 84. An electric push rod 86 is fixedly connected to one side of the support plate 702, and its output end is fixedly connected to the upper surface of the movable plate 82. The cleaning device 8, located on one side of the movable plate 82, effectively cleans the printing plate placed on the upper surface of the machine body 1, preventing impurities on the printing plate from interfering with the laser engraving machine, ensuring engraving accuracy, improving processing stability, and reducing rework rate. A fixed plate 87 is fixedly connected to one side of the movable plate 82, and a blade 88 is fixedly connected to the lower surface of the fixed plate 87. This allows for convenient cutting of a portion of the adhesive paper 85 after use using the blade 88. A protective sleeve 89 is slidably connected to one side of the fixed plate 87. The length of the protective sleeve 89 is adapted to the length of the blade 88. This protects the blade 88, preventing it from causing cuts to the operator when not in use and improving operational safety.

[0035] The working principle of the laser engraving machine for plate positioning provided by this utility model is as follows: During the engraving process of the plate using the laser engraving machine, because laser engraving will cause slight displacement of the plate, in order to prevent the plate from moving and causing engraving failure, a clamping device 7 is required. First, the plate is placed on the upper surface of the machine body 1, the plate is moved and adjusted to a suitable position, and then the motor 714 is turned on. The rotation of the motor 714 drives the active bevel gear 713 to rotate. The rotation of the active bevel gear 713 drives the driven bevel gear 712, which meshes with the active bevel gear 713, to rotate. The rotation of the driven bevel gear 712 drives the double-threaded screw... Rotating rod 703 causes the two support plates 702 to move closer together along slide rail 701. Once the support plates 702 are in the correct position, rotating the bidirectional screw 704 causes the two moving blocks 705 connected by the arc thread of the bidirectional screw 704 to move closer together. The two moving blocks 705 moving closer together cause the connecting rod 706 to rotate and press down, pushing the pressure plate 708 to move downward along the slide groove 710 with the help of the sliding plate 711 to press the plate to be engraved. After the plate is engraved, rotating the bidirectional screw 704 again causes the two moving blocks 705 to move away, causing the connecting rod 706 to rotate, causing the pressing plate 708 to rise and release the processed plate.

[0036] During laser engraving of the plate, dust on the plate surface can affect the engraving accuracy. To reduce dust on the plate surface, the cleaning device 8 is used. First, the electric push rod 86 is turned on, and the electric push rod 86 pushes the moving plate 82 down along the sliding groove 81. When the moving plate 82 moves down to a suitable height, the plate is pushed into the machine body 1 from the side near the control box 6. At this time, the adhesive paper 85 will roll due to the pushed plate. By utilizing the continuous contact during the rolling process, the adhesive surface can pick up as much debris as possible. A layered structure is adopted. When the surface adhesive layer is full of debris, the outermost dirty adhesive paper of the adhesive paper 85 can be cut off with the blade 88 to expose a new adhesive layer for continued use, which is convenient for reuse and maintains the adsorption effect. When the plate surface is cleaned, the electric push rod 86 is turned off and retracted, causing the moving plate 82 to move upward.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
