[0002] Laser engraving is based on CNC technology and uses laser as the processing medium. The physical transformation of the processing material into instant melting and vaporization under the irradiation of laser engraving can enable laser engraving to achieve the processing purpose. Laser engraving is to use laser technology to write words on objects. The words engraved by this technology have no scratches, the surface of the object is still smooth, and the words will not be worn.

[0003] In the process of laser engraving, the existing wooden frames are often processed simultaneously on multiple wooden frames. However, during the processing of the frames, the existing laser engraving machine for processing wooden frames usually clamps and fixes the frames side by side on the same horizontal plane before performing laser engraving.

[0004] However, since there are certain deviations in the length and thickness of each frame, the length of the frame is not aligned after being fixed, or the processing surface is not on the same level, or there is a deviation in the levelness of the processing surface, which leads to different positions and depths of laser engraving on each frame, affecting the aesthetics of the frame.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0034] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0036] like Figure 1-Figure 8 As shown, a laser engraving machine for processing a wooden mirror frame provided by the present invention comprises a workbench 1, wherein the upper end surface of the workbench 1 is fixedly connected with a plurality of positioning seats 2 in parallel, and the side walls of each positioning seat 2 are inclinedly arranged, and one end of the workbench 1 is fixedly connected with a No. 1 fixing frame 9, and the No. 1 fixing frame 9 is fixedly connected with a plurality of No. 3 electric telescopic rods 10 in parallel, and the telescopic ends of the No. 3 electric telescopic rods 10 are fixedly connected with laser emitting tubes 11, and each laser emitting tube 11 is arranged on one side of a positioning seat 2, and a No. 2 fixing frame 12 is arranged on the side of each positioning seat 2 away from the laser emitting tube 11, and the No. 2 fixing frame 12 is fixedly connected with a No. 4 electric telescopic rod 13 that can be lifted and lowered vertically, and the telescopic part of the No. 4 electric telescopic rod 13 is fixedly connected with a fixing plate 14;

[0037] The lower end surface of the fixed plate 14 is connected to two pressure mechanisms 4, and the two pressure mechanisms 4 can cooperate with the posture adjustment mechanism 3 to adjust and fix the posture of the frame. The fixed plate 14 is connected with the posture adjustment mechanism 3, and the posture adjustment mechanism 3 can adjust the inclination of the frame in the positioning seat 2 relative to the horizontal plane; the fixed plate 14 is provided with a power component 5, and the power component 5 can drive the two pressure mechanisms 4 on the fixed plate 14 to move relative to or towards each other at the same time, and all the pressure mechanisms 4 are connected to a dust removal mechanism 6, and the dust removal mechanism 6 can absorb and filter the dust around the frame through the pressure mechanism 4; the fixed plate 14 is connected with a suction mechanism 7, and the suction mechanism 7 can adsorb and fix the center of the upper surface of the frame;

[0038] The lower end faces of the fixing plates 14 are fixedly connected to the limiting plates 15 , and the other side of the positioning seats 2 away from the limiting plates 15 is provided with limiting mechanisms 8 , which can simultaneously push one end of the mirror frames on all the positioning seats 2 to abut against the limiting plates 15 .

[0039] In this embodiment, multiple frames are placed in each positioning seat 2 at the same time, and the sides of the frames are in contact with the side walls of the positioning seat 2. The limiting mechanism 8 is activated, and the limiting mechanism 8 simultaneously pushes the multiple frames to move horizontally in each positioning seat 2 until one end of each frame is in contact with each limiting plate 15, so that one end of each frame is aligned.

[0040] Then, the pressure mechanism 4 is started, and the pressure mechanism 4 and the positioning seat 2 clamp the frame together. At this time, the posture adjustment mechanism 3 is started to adjust the upper and lower surfaces of the frame to the horizontal direction. Then, the posture adjustment mechanism 3 and the pressure mechanism 4 are started to clamp the frame to rise. The suction mechanism 7 can adsorb and fix the center of the upper surface of the frame, thereby preventing the frame from being horizontally offset in the future; until all the frames compress the suction mechanism 7 to the extreme, at which time the upper surfaces of all the frames are at the same horizontal position;

[0041] Through the cooperation of the posture adjustment mechanism 3, the pressure mechanism 4, the suction mechanism 7 and the limiting mechanism 8, one end of all the frames are aligned and the upper surfaces of all the frames are in the same horizontal position. Furthermore, the suction mechanism 7 can adsorb and fix the center of the upper surface of the frame.

[0042] Start each laser emitting tube 11 to laser engrave each frame, and at the same time start each No. 3 electric telescopic rod 10 to drive each laser emitting tube 11 to move along the length direction of the frame; during the laser engraving process of the frame, start the dust removal mechanism 6 to absorb and filter the dust around the frame.

[0043] like Figure 6 As shown, a laser engraving machine for processing wooden mirror frames provided by the present invention, the posture adjustment mechanism 3 includes a first electric telescopic rod 31, a support frame 32, a rotating shaft 33, a conveyor belt 34 and a first motor 35;

[0044] The lower end surface of the pressure mechanism 4 is fixedly connected to two No. 1 electric telescopic rods 31, and the telescopic ends of the No. 1 electric telescopic rods 31 are fixedly connected to support frames 32. The inclination of the support frames 32 is the same as the side wall of the positioning seat 2. Both ends of the support frames 32 are rotatably connected to rotating shafts 33. The two rotating shafts 33 are commonly connected to a conveyor belt 34 on the outside. The support frame 32 is fixedly connected to a No. 1 motor 35, and the output shaft of the No. 1 motor 35 is fixedly connected to the rotating shaft 33.

[0045] In this embodiment, the No. 1 electric telescopic rod 31 is started, so that the two support frames 32 are aligned with the side walls of the positioning seat 2 respectively. At this time, the side walls of the frame are in contact with the two support frames 32 at the same time, and the No. 1 motor 35 is started. The No. 1 motor 35 drives the rotating shaft 33 to rotate, and the conveyor belt 34 moves around the two rotating shafts 33. At this time, the conveyor belt 34 drives the frame to rotate through friction, thereby adjusting the upper and lower surfaces of the frame to a horizontal position.

[0046] like Figure 7 and Figure 8 As shown, a laser engraving machine for processing wooden mirror frames provided by the present invention, the pressure mechanism 4 includes a second electric telescopic rod 41, a rotating seat 42, a rotating sleeve 43 and a rubber roller 44;

[0047] The lower end surface of the fixed plate 14 is slidably connected with two No. 2 electric telescopic rods 41, and the telescopic ends of the No. 2 electric telescopic rods 41 are both embedded with a rotating seat 42, and a pressure sensor is arranged between the upper end surface of the rotating seat 42 and the No. 2 electric telescopic rod 41, and the rotating seat 42 is rotatably connected with a rotating sleeve 43, and a driving component for driving the rotating sleeve 43 to rotate is arranged in the rotating seat 42 (the driving component is composed of a motor and a gear transmission pair, and the motor drives the rotating sleeve 43 to rotate through the gear transmission pair), and the rotating sleeve 43 is fixedly connected with a rubber roller 44, and the outer side wall of the rubber roller 44 is provided with a plurality of rubber scrapers in the same spiral direction.

[0048] In this embodiment, the two second electric telescopic rods 41 are started to extend synchronously, and the telescopic ends of the two second electric telescopic rods 41 respectively drive the rubber rollers 44 connected thereto to move downward, and the bottoms of the two rubber rollers 44 are kept at the same level. The two rubber rollers 44 are in contact with the mirror frame. At this time, under the reverse thrust of the mirror frame, the two rubber rollers 44 drive the rotating seat 42 to squeeze the second electric telescopic rod 41, and the pressure difference between the two pressure sensors can be used to determine whether the upper surface of the mirror frame is horizontal.

[0049] When the pressure difference between the two pressure sensors exceeds a set pressure difference threshold, the posture adjustment mechanism 3 is activated to accurately adjust the horizontality of the frame.

[0050] like Figure 5 As shown, a laser engraving machine for processing wooden mirror frames provided by the present invention, the power assembly 5 includes a No. 2 motor 51 and a bidirectional screw 52, ​​the fixed plate 14 is fixedly connected with the No. 2 motor 51, the output shaft of the No. 2 motor 51 is fixedly connected with the bidirectional screw 52, ​​and the bidirectional screw 52 is threadedly connected to two No. 2 electric telescopic rods 41 slidably connected to the fixed plate 14.

[0051] In this embodiment, firstly, the two No. 2 electric telescopic rods 41 on the upper side of each mirror frame are started to extend, and the No. 2 electric telescopic rods 41 drive the rubber rollers 44 connected thereto to move downward until the two rubber rollers 44 on the upper side of each mirror frame are in contact with the mirror frame;

[0052] Then, the No. 2 motor 51 is started, and the No. 2 motor 51 drives the connected bidirectional screw 52 to rotate, and the bidirectional screw 52 drives the two connected No. 2 electric telescopic rods 41 to move horizontally through thread transmission, and the two No. 2 electric telescopic rods 41 can drive the connected rubber rollers 44 to move from the middle of the mirror frame to both sides. At this time, under the push of the two rubber rollers 44, the upper surface of the mirror frame in the positioning seat 2 is gradually adjusted to a direction parallel to the horizontal plane; in this process, the driving component is started to drive the rotating sleeve 43 to rotate, and the rotating sleeve 43 drives the rubber roller 44 to rotate, so that when the rubber roller 44 moves along the upper surface of the mirror frame, the rubber roller 44 can remove dust from the upper surface of the mirror frame;

[0053] When the two rubber rollers 44 move to the positions on both sides of the upper surface of the frame, the pressure difference between the two pressure sensors is observed. When the pressure difference between the two pressure sensors exceeds the set pressure difference threshold, the posture adjustment mechanism 3 is activated to accurately adjust the horizontality of the frame.

[0054] like Figure 3 As shown, a laser engraving machine for processing wooden mirror frames provided by the present invention, the dust removal mechanism 6 includes a filter box 61, a No. 1 air pump 62 and a No. 1 hose 63;

[0055] The filter box 61 is fixedly connected to the No. 4 electric telescopic rod 13, and the filter box 61 is connected to the No. 1 air pump 62. The No. 1 air pump 62 is connected to all the rotating sleeves 43 through the No. 1 hose 63. The rubber scrapers on the rubber rollers 44 are all provided with guide grooves 16, and the guide grooves 16 are all connected to the rotating sleeves 43.

[0056] In this embodiment, when the rotating sleeve 43 drives the rubber roller 44 to rotate, the No. 1 air pump 62 is started to inhale air, and the dust on the upper surface of the frame and nearby is sucked into the rotating sleeve 43 through the guide groove 16, and then the dust is sent to the filter box 61 through the No. 1 hose 63 for filtration and collection; under the action of the dust removal mechanism 6, the dust and impurities on the upper surface of the frame can be removed, thereby facilitating the suction mechanism 7 to adsorb the upper surface of the frame, and at the same time facilitating the laser engraving accuracy of the frame by the laser emitting tube 11.

[0057] like Figure 3 and Figure 4 As shown, a laser engraving machine for processing wooden mirror frames provided by the present invention, the suction mechanism 7 includes an elastic telescopic sleeve 71, a rubber suction cup 72, a second air pump 73 and a second hose 74;

[0058] The fixed plates 14 are all fixedly connected with elastic telescopic sleeves 71 , and the telescopic ends of the elastic telescopic sleeves 71 are all fixedly connected with rubber suction cups 72 . The filter box 61 is connected with a No. 2 air pump 73 , and the No. 2 air pump 73 is connected to all the elastic telescopic sleeves 71 through a No. 2 hose 74 .

[0059] In this embodiment, after the upper surface of the frame is adjusted to a horizontal position, the two No. 2 electric telescopic rods 41 and the two No. 1 electric telescopic rods 31 are simultaneously started to contract, and under the clamping force of the support frame 32 and the rubber roller 44, the frame is lifted upward, and then the upper surface of the frame contacts the rubber suction cup 72 until the elastic telescopic sleeve 71 is compressed to the extreme. At this time, the upper surfaces of all the frames are at the same water level, and at the same time, each rubber suction cup 72 is adsorbed and fixed at the center position of the upper surface of each frame.

[0060] like Figure 2As shown, a laser engraving machine for processing wooden mirror frames provided by the present invention, the limiting mechanism 8 includes a fixing seat 81, a telescopic cylinder 82, a rubber disc 83, a No. 3 air pump 84 and a No. 3 hose 85;

[0061] A plurality of fixing seats 81 are arranged side by side on the upper end surface of the workbench 1, and each of the fixing seats 81 is fixedly provided with a telescopic cylinder 82, and the telescopic ends of the telescopic cylinder 82 are fixedly connected with a rubber disk 83, and the rubber disk 83 is directly opposite to the positioning seat 2, and all the rubber disks 83 are connected to the No. 3 air pump 84 through the No. 3 hose 85.

[0062] In this embodiment, the No. 3 air pump 84 is started, and the No. 3 air pump 84 inflates all the telescopic cylinders 82 at the same time. All the telescopic cylinders 82 push the rubber disks 83 forward at the same time. At this time, each rubber disk 83 pushes one end of each frame to contact each limit plate 15 at the same time with the same air pressure, so that one end of each frame is flush.

[0063] Working principle:

[0064] Put multiple frames in each positioning seat 2 at the same time, and the sides of the frames are in contact with the side walls of the positioning seat 2. Start the third air pump 84, and the third air pump 84 will inflate all telescopic cylinders 82 at the same time. All telescopic cylinders 82 will push the rubber discs 83 forward at the same time. At this time, each rubber disc 83 pushes one end of each frame to contact with each limit plate 15 at the same time with the same air pressure, so that one end of each frame is flush.

[0065] Then, the two second electric telescopic rods 41 on the upper side of each mirror frame are first started to extend, and the second electric telescopic rods 41 drive the rubber rollers 44 connected thereto to move downward until the two rubber rollers 44 on the upper side of each mirror frame are in contact with the mirror frame;

[0066] Then, the No. 2 motor 51 is started, and the No. 2 motor 51 drives the connected bidirectional screw 52 to rotate, and the bidirectional screw 52 drives the two connected No. 2 electric telescopic rods 41 to move horizontally through thread transmission, and the two No. 2 electric telescopic rods 41 can drive the connected rubber rollers 44 to move from the middle of the mirror frame to both sides. At this time, under the push of the two rubber rollers 44, the upper surface of the mirror frame in the positioning seat 2 is gradually adjusted to a direction parallel to the horizontal plane; in this process, the driving component is started to drive the rotating sleeve 43 to rotate, and the rotating sleeve 43 drives the rubber roller 44 to rotate, so that when the rubber roller 44 moves along the upper surface of the mirror frame, the rubber roller 44 can remove dust from the upper surface of the mirror frame;

[0067] When the two rubber rollers 44 move to the positions on both sides of the upper surface of the frame, the pressure difference between the two pressure sensors is observed. When the pressure difference between the two pressure sensors exceeds the set pressure difference threshold, the No. 1 electric telescopic rod 31 is started, so that the two support frames 32 are respectively aligned with the side walls of the positioning seat 2. At this time, the side walls of the frame are in contact with the two support frames 32 at the same time, and the No. 1 motor 35 is started. The No. 1 motor 35 drives the rotating shaft 33 to rotate, and the conveyor belt 34 moves around the two rotating shafts 33. At this time, the conveyor belt 34 drives the frame to rotate by friction, so that the upper and lower surfaces of the frame are accurately adjusted to a horizontal position;

[0068] Start the pressure mechanism 4, which clamps the frame together with the positioning seat 2. At this time, start the posture adjustment mechanism 3 to adjust the upper and lower surfaces of the frame to the horizontal direction. Then start the posture adjustment mechanism 3 and the pressure mechanism 4 to clamp the frame to rise. The suction mechanism 7 can adsorb and fix the center of the upper surface of the frame, thereby avoiding subsequent horizontal deviation of the frame; until all the frames compress the suction mechanism 7 to the extreme, at this time the upper surfaces of all the frames are in the same horizontal position, and then start the limiting mechanism 8 to further limit and fix all the frames horizontally.

[0069] When the upper surface of the mirror frame is adjusted to a horizontal position, the two No. 2 electric telescopic rods 41 and the two No. 1 electric telescopic rods 31 are simultaneously activated to contract, and the mirror frame is lifted upward under the clamping force of the support frame 32 and the rubber roller 44, and then the upper surface of the mirror frame contacts the rubber suction cup 72 until the elastic telescopic sleeve 71 is compressed to the extreme, at which time the upper surfaces of all the mirror frames are at the same water level, and at the same time, each rubber suction cup 72 is adsorbed and fixed at the center position of the upper surface of each mirror frame;

[0070] Through the cooperation of the posture adjustment mechanism 3, the pressure mechanism 4, the suction mechanism 7 and the limiting mechanism 8, one end of all the frames are aligned, and the upper surfaces of all the frames are at the same horizontal position. Furthermore, the suction mechanism 7 can adsorb and fix the center of the upper surface of the frame;

[0071] When the two rubber rollers 44 move to the positions on both sides of the upper surface of the frame respectively, the driving assembly is started to drive the rotating sleeve 43 to rotate, and the rotating sleeve 43 drives the rubber scraper on the rubber roller 44 to elastically squeeze the side wall of the frame, and the two sides of the frame are elastically limited by the rubber scraper, and the rubber suction cup 72 is adsorbed on the center position of the upper surface of each frame, which effectively improves the stability of the frame and prevents the frame from being displaced due to external vibration during the laser engraving process; in the above scheme, the posture adjustment mechanism 3, the pressure mechanism 4, the suction mechanism 7 and the limiting mechanism 8 are used to achieve effective fixation of multiple frames at the same time, while avoiding rigid extrusion of the upper and lower surfaces of the frame to cause indentations, thereby effectively protecting the surface of the frame.

[0072] Start each laser emitting tube 11 to laser engrave each frame, and at the same time start each No. 3 electric telescopic rod 10 to drive each laser emitting tube 11 to move along the length direction of the frame; during the laser engraving process of the frame, start the dust removal mechanism 6 to absorb and filter the dust around the frame.
