Description

Technical Field

[0001] This invention relates to the field of laser marking machine technology, specifically to a laser marking machine capable of precise loading and unloading. Background Technology

[0002] When it is necessary to permanently mark square and round metal plates produced, laser marking machines are usually used. Laser marking machines use high-energy laser beams to irradiate the metal surface, performing intelligent heat treatment on the metal surface, raising its temperature, causing melting, ablation, or evaporation, thereby forming a mark. This results in high-quality marking. However, existing laser marking machines require manual adjustment of the workpiece to place it in the correct marking position when loading the metal plate. This operation is relatively cumbersome. Furthermore, manual adjustment of the workpiece position is not only prone to positional deviations but also has low efficiency, thus affecting the marking efficiency. In addition, existing marking machines require manual loading and unloading, making them inconvenient to use. Summary of the Invention

[0003] The purpose of this invention is to provide a laser marking machine that can achieve precise loading and unloading, so as to solve the problems mentioned in the background art that the existing marking machines require manual adjustment of the workpiece position and are not convenient to use.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A laser marking machine capable of precise loading and unloading includes: a marking machine body, on which a laser emitter is fixedly mounted, and laser is emitted by the laser emitter to perform marking; A feeding assembly is installed on the body of the marking machine, and materials are fed through the feeding assembly. A feeding assembly is installed on the feeding assembly. After the metal sheet is marked, it is fed out through the feeding assembly. A position adjustment component is also installed on the feeding component. During the feeding process, the feeding component drives the position adjustment component to move, thereby adjusting the position of the metal plate to achieve precise feeding.

[0005] Furthermore, a support frame is fixedly installed on the body of the marking machine, and a guide support rod is fixedly installed on the support frame.

[0006] Furthermore, the feeding assembly includes a hydraulic rod, which is fixedly mounted on the support frame; The feeding plate is fixedly installed on the hydraulic rod. The hydraulic rod drives the feeding plate to move, and the feeding plate drives the metal plate to move to complete the loading and unloading.

[0007] Furthermore, the feeding plate is provided with a feeding channel, and the metal sheet slides down from the feeding channel when it is being fed.

[0008] Furthermore, the feeding assembly includes: a movable support block, which is movably mounted on the feeding support plate; A material support plate is movably installed in the material feeding channel.

[0009] Furthermore, a movable connecting rod is fixedly provided at the lower end of the movable support block, a support bottom strip is fixedly provided at the lower end of the movable connecting rod, and a support top block is fixedly provided on the support bottom strip.

[0010] Furthermore, when the support plate is in a horizontal state, it supports the metal plate, and the support plate is supported by the support top block.

[0011] Furthermore, the position adjustment assembly includes: a drive engagement frame, which is movably mounted on the feeding support plate; The first adjusting block, there are two of them, which are symmetrically installed at both ends of the feeding plate and movably connected to the drive frame; The second adjusting block, there are two of them, which are symmetrically installed on both sides of the feeding plate.

[0012] Furthermore, the first adjusting block is moved by the drive frame, and the first adjusting block drives the second adjusting block to move, thereby adjusting the position of the circular metal plate through the cooperation of the first and second adjusting blocks.

[0013] Furthermore, conversion strips are movably mounted on both the first and second adjustment blocks, and the position of the square metal plate is adjusted by the cooperation between the conversion strips, the first adjustment block, and the second adjustment block.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages: 1. When marking metal sheets, the staff only needs to place the metal sheet on the support plate, and the feeding support plate will bring the metal sheet to the marking point. During the feeding process, the metal sheet can be automatically adjusted to be in the correct position without the need for staff to make adjustments. It is very convenient and can achieve accurate and fast feeding.

[0015] 2. After marking is completed, the feeding plate will rotate downwards under the action of gravity as it moves in the opposite direction. This will allow the metal plates on the feeding plate to slide down automatically for collection, eliminating the need for manual unloading and simplifying the work process for staff, thus reducing their workload.

[0016] 3. In addition, the cooperation between the first adjusting block and the conversion strip, as well as the cooperation between the second adjusting block and the conversion strip, enables the positional adjustment of square and round metal plates, achieving precise feeding of both plate types and providing strong adaptability.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] This invention provides a technical solution: like Figure 1 and Figure 2As shown, a laser marking machine capable of precise loading and unloading includes: a marking machine body 1, a feeding component, an unloading component, and a position adjustment component. A laser emitter 11 is fixedly mounted on the marking machine body 1 with screws, and the laser emitter 11 emits laser light for marking. The feeding component is mounted on the marking machine body 1 and moves the metal plate so that it can accurately move below the laser emitter 11 to complete the loading, facilitating the laser emitter 11 to perform the marking operation smoothly. The unloading component is mounted on the feeding component, and the metal plate is unloaded after marking, eliminating the need for manual unloading and greatly reducing the workload of the staff. The position adjustment component is also mounted on the feeding component. During the loading process, the feeding component moves the position adjustment component, which adjusts the position of the metal plate to achieve precise loading and thus ensure the quality of marking.

[0031] like Figure 1 and Figure 2 As shown, a support frame 12 is welded and fixed on the body 1 of the marking machine by welding process. A matching drive bar 13 is integrally formed and fixed on the upper end of the support frame 12. A drive matching ramp 14 is provided on the matching drive bar 13, and the surface of the matching drive bar 13 is smooth and burr-free. In addition, a guide support rod 15 is welded and fixed on the support frame 12 by welding process. A retaining slide 16 is opened on one side of the support frame 12. The inner wall of the retaining slide 16 is smooth and burr-free. A lower convex bearing plate 17 is integrally formed and fixed on the end of the support frame 12. A downward sliding slide 18 is opened at one end of the retaining slide 16. The downward sliding slide 18 is connected to the retaining slide 16 and extends to the lower convex bearing plate 17.

[0032] like Figure 2 and Figure 6 As shown, the feeding assembly includes a hydraulic rod 2 and a feeding plate 3. The hydraulic rod 2 is fixedly installed on the support frame 12 by screws, and the hydraulic rod 2 operates under the control of a controller in the prior art.

[0033] A connecting frame 35 is integrally formed and fixed on one side of the feeding plate 3. A mating plate 36 is welded and fixed on the connecting frame 35. The mating plate 36 is fixedly connected to the hydraulic rod 2 by bolts. The feeding plate 3 is then fixedly installed on the hydraulic rod 2 by the mating plate 36. The hydraulic rod 2 drives the feeding plate 3 to move, and the feeding plate 3 drives the metal plate to move to complete the loading and unloading. In addition, a guide support hole 361 is opened on the mating plate 36. A guide support rod 15 is inserted into the guide support hole 361. The cooperation between the guide support rod 15 and the guide support hole 361 provides guidance and support for the mating plate 36, ensuring the stability of the feeding plate 3 during movement.

[0034] like Figure 6 As shown, a feeding support plate 3 has a feeding channel 31. When the metal plate is fed, it slides down from the feeding channel 31. A matching plate frame 32 is welded and fixed in the feeding channel 31 by welding process. Movable grooves 33 are provided at both ends and sides of the feeding support plate 3. A supporting inner rod 34 is welded and fixed in the movable groove 33 by welding process. A matching support strip 38 is integrally formed and fixed at the lower end of the matching support plate 36. A movable insertion hole 381 is provided on the matching support strip 38.

[0035] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the feeding assembly includes a movable support block 9 and a feeding plate 95. The lower end of the movable support block 9 is welded and fixed with a movable connecting rod 92. The movable connecting rod 92 is inserted into the movable insertion hole 381 on the supporting bar 38. The movable support block 9 is movably installed on the feeding plate 3 through the cooperation of the movable connecting rod 92 and the movable insertion hole 381. A linkage support column 91 is also welded and fixed on the movable support block 9 through a welding process. The surface of the linkage support column 91 is smooth and burr-free.

[0036] The material support plate 95 is hinged to the mating plate frame 32 in the material feeding channel 31. When the material support plate 95 is in a horizontal state, its upper end face is flush with the upper end face of the feeding support plate 3.

[0037] The lower end of the movable connecting rod 92 is welded and fixed with a support bottom strip 93. A support top block 94 is integrally formed and fixed on the support bottom strip 93. The support top block 94 is located on the lower side of the feeding channel 31.

[0038] like Figure 3 , Figure 4 and Figure 5 As shown, when the support plate 95 is in a horizontal state, it supports the metal sheet. The support top block 94 supports the support plate 95, that is, the support top block 94 is in contact with the lower end face of the support plate 95. At this time, the linkage support column 91 is inserted into the retaining slide 16 and is in contact with the inner wall of the retaining slide 16. When the metal sheet is unloaded, the support plate 95 rotates downward and is in an inclined state. In this way, the metal sheet slides off the support plate 95 under its own weight. At this time, the linkage support column 91 is inserted into the downward slide 18 and is in contact with the inner wall of the downward slide 18. When unloading is required, a container should be placed at one end of the marking machine body 1. In this way, when the support plate 95 rotates downward to an inclined state, the metal sheet can slide down from the support plate 95 into the container to achieve automatic unloading and collection.

[0039] like Figure 6As shown, protruding ear plates 37 are symmetrically and integrally formed and fixed on both sides of the upper end of the mating support plate 36. A mating through hole 371 is opened on the protruding ear plate 37. A mating frame 39 is symmetrically welded and fixed on both sides of the feeding support plate 3 by welding process. A moving slide groove 391 is opened on the mating frame 39. The inner wall of the moving slide groove 391 is smooth and burr-free.

[0040] like Figure 3 , Figure 4 and Figure 7 As shown, the position adjustment assembly includes: a drive engagement frame 4, a first adjustment block 5, and a second adjustment block 6. The upper end of the drive engagement frame 4 is equipped with a friction-reducing roller 41, and a movable engagement rod 42 is symmetrically welded and fixed to the lower end of the drive engagement frame 4 by welding. The movable engagement rod 42 is inserted into the engagement through hole 371. The drive engagement frame 4 is movably mounted on the engagement support plate 36 on the feeding support plate 3 by the engagement of the movable engagement rod 42 and the engagement through hole 371. A support base plate 43 is welded and fixed to the lower end of the movable engagement rod 42 by welding. In addition, a first engagement spring 44 is sleeved on the movable engagement rod 42. The first engagement spring 44 is located below the protruding ear plate 37, and the two ends of the first engagement spring 44 are welded and fixed to the support base plate 43 and the protruding ear plate 37, respectively.

[0041] There are two first adjusting blocks 5, which are symmetrically installed at both ends of the feeding support plate 3 and movably connected to the drive engagement frame 4. Specifically, an L-shaped support plate 72 is welded to the first adjusting block 5 by welding process. The L-shaped support plate 72 has a support limiting hole 73, and a support inner rod 34 is inserted into the support limiting hole 73. A first support plate 45 is symmetrically welded to the support base plate 43 on the side of the drive engagement frame 4 near the feeding support plate 3 by welding process. A second support plate 46 is welded to the first support plate 45 by welding process. A push connecting rod 47 is hinged to the second support plate 46. The lower end of the push connecting rod 47 is hinged to the L-shaped support plate 72 on the first adjusting block 5. The movable connection between the first adjusting block 5 and the drive engagement frame 4 is realized through the push connecting rod 47.

[0042] There are two second adjusting blocks 6, which are symmetrically installed on both sides of the feeding support plate 3. Specifically, an L-shaped support plate 72 is also welded and fixed on the second adjusting block 6 by welding process. The L-shaped support plate 72 has a support limiting hole 73. A support inner rod 34 is inserted into the support limiting hole 73, and a second cooperating spring 61 is sleeved on the support inner rod 34 on which the second adjusting block 6 is installed. The two ends of the second cooperating spring 61 are respectively welded and fixed to the inner wall of the moving groove 33 and the L-shaped support plate 72 on the second adjusting block 6.

[0043] like Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, both the first adjusting block 5 and the second adjusting block 6 are integrally formed with mating arc grooves 71. The inner wall of the mating arc grooves 71 is smooth and burr-free. The mating arc grooves 71 can be adjusted and limited by mating with the circular metal plate. Both the first adjusting block 5 and the second adjusting block 6 are symmetrically provided with insertion sockets 74. The L-shaped support plate 72 is symmetrically provided with limiting insertion holes 75. In addition, the L-shaped support plate 72 on the first adjusting block 5 is symmetrically welded and fixed with contact pushers 51 by welding process. The surface of the contact pushers 51 is smooth and burr-free.

[0044] The first adjusting block 5 is moved by the drive mounting bracket 4. When the drive mounting bracket 4 moves up and down, the first adjusting block 5 can move along the inner support rod 34 under the action of the push rod 47. In addition, a rotary drive rod 62 is symmetrically hinged to the L-shaped support plate 72 on the second adjusting block 6. A matching connecting block 63 is welded to the lower end of the rotary drive rod 62. The surface of the matching connecting block 63 is smooth and burr-free. The matching connecting block 63 is inserted into the moving slide 391 and contacts the inner wall of the moving slide 391. The contact pusher 51 on the first adjusting block 5 contacts the rotary drive rod 62. When the first adjusting block 5 moves towards the support plate 95, the contact pusher 51 will push the rotary drive rod 62 to move, thereby realizing that the first adjusting block 5 drives the second adjusting block 6 to move. The position of the circular metal plate is adjusted by the cooperation of the first adjusting block 5 and the second adjusting block 6.

[0045] Both the first adjusting block 5 and the second adjusting block 6 are movably mounted with conversion strips 8. Specifically, one end of the conversion strip 8 is integrally formed and fixedly provided with a filler block 81. The surface of the filler block 81 is smooth and burr-free. The other end of the conversion strip 8 is integrally formed and symmetrically fixedly provided with support protrusions 82. An elastic connecting piece 83 is welded and fixedly provided on the support protrusion 82 by welding process. A locking strip 84 is welded and fixedly provided on the elastic connecting piece 83. The lower end of the locking strip 84 is integrally formed and fixedly provided with a locking insert plate 842. When the filler block 81 is on the upper side of the mating arc groove 71, the locking insert plate 842 is inserted into the insertion socket 74. Through the mating of the locking insert plate 842 and the insertion socket 74... The conversion strip 8 is locked together. A lower support block 85 is integrally formed and fixed at the lower end of the supporting protrusion 82. A mating support hole 86 is opened on the lower support block 85. A mating support column 841 is also welded and fixed on the locking strip 84 by welding process. The mating support column 841 is inserted into the mating support hole 86. The mating support hole 86 and the mating support column 841 provide further support and guidance for the locking strip 84. In addition, a limit guide rod 87 is welded and fixed at the lower end of the supporting protrusion 82 by welding process. The limit guide rod 87 is inserted into the limit insertion hole 75. The mating of the limit guide rod 87 and the limit insertion hole 75 provides a limit function for the conversion strip 8.

[0046] The position of the square metal plate is adjusted by the cooperation between the conversion strip 8, the first adjusting block 5, and the second adjusting block 6. That is, the conversion strip 8 moves downward so that the filling block 81 is inserted into the mating arc groove 71 to fill the mating arc groove 71. In this way, the end faces of the first adjusting block 5 and the second adjusting block 6 with the mating arc groove 71 are in a flat state, so that they can contact the square metal plate to adjust and limit its position.

[0047] When marking metal plates, the metal plates are placed between the first adjusting block 5 and the second adjusting block 6. Then, the hydraulic rod 2 drives the feeding plate 3 to move. As the feeding plate 3 moves, the friction-reducing roller 41 on the drive mating frame 4 will come into contact with the drive mating ramp 14 on the mating drive bar 13. Under the action of the drive mating ramp 14, the drive mating frame 4 will be pushed down. As the drive mating frame 4 moves down, under the action of the push rod 47, the two first adjusting blocks 5 will move towards each other.

[0048] As the first adjusting block 5 moves towards each other, it pushes the rotary drive rod 62 to move and rotate under the action of the contact pusher 51. As the rotary drive rod 62 moves and rotates, it pushes the second adjusting block 6 towards the metal plate, causing the two second adjusting blocks 6 to move towards each other. When both the first adjusting block 5 and the second adjusting block 6 move towards the metal plate, they will contact the metal plate, thus pushing the metal plate to move to the accurate position. At this time, the metal plate is supported by the support plate 95. Then, as the feeding support plate 3 moves, the metal plate can be brought to the bottom of the laser emitter 11 for marking. The metal plate is now in the correct marking position, which is very convenient and accurate, and can fully guarantee the marking quality.

[0049] After marking is completed, the hydraulic rod 2 drives the feeding plate 3 to move in the opposite direction. When the drive engagement frame 4 moves in the opposite direction, during the process of the anti-friction roller 41 contacting the drive engagement ramp 14, the drive engagement frame 4 moves upward under the action of the first engagement spring 44 to reset until the anti-friction roller 41 passes the drive engagement ramp 14, at which point the drive engagement frame 4 is reset. During the upward reset process of the drive engagement frame 4, the push rod 47 pulls the first adjusting block 5 to move in the opposite direction. As the first adjusting block 5 moves in the opposite direction, the rotating drive rod 62 loses its contact with the push frame 51, thereby causing the second adjusting block 6 to lose its restriction. Thus, under the action of the second engagement spring 61, the second adjusting block 6 is pushed to move in the opposite direction to reset. This causes the metal plate to separate from the first adjusting block 5 and the second adjusting block 6. After the anti-friction roller 41 passes the drive engagement ramp 14, the hydraulic rod 2 drives the feeding plate 3 to continue moving, causing the linkage support column 91 on the moving plate 9 to enter the downward slide 18. In this way, with the cooperation of the downward slide 18 and the linkage support column 91, the moving plate 9 will be driven to move downward. As the moving plate 9 moves downward, the support top block 94 will no longer support the material plate 95. Thus, under the action of the gravity of the metal plate and the material plate 95, the material plate 95 will rotate downward and tilt, so that the metal plate can slide down from the material plate 95 into the container, realizing automatic material unloading and collection without the need for personnel to collect it. After the material is placed, the hydraulic rod 2 drives the feeding plate 3 to reset. At this time, with the cooperation of the lower slide 18 and the linkage support column 91, the moving support block 9 will move upward until the linkage support column 91 re-enters the holding slide 16. During this process, as the moving support block 9 moves upward, it will also drive the support top block 94 to move upward. Then, under the action of the support top block 94, the material plate 95 will be pushed upward to rotate into a horizontal state, so that the metal plate can be placed again.

[0050] When it is necessary to feed and mark a square metal plate, pull the locking strip 84 to disengage the locking insert 842 from the insertion socket 74. This unlocks the conversion strip 8, allowing it to move downwards and insert the filling block 81 into the mating groove 71. The filling groove 71 is filled, ensuring that the end faces of the first adjusting block 5 and the second adjusting block 6 with the mating groove 71 are flat. This allows the first adjusting block 5 and the second adjusting block 6 to make good contact with the square metal plate, facilitating its movement and adjustment. Ultimately, this effectively restricts the square metal plate to the correct position, ensuring smooth marking. The operation is simple, convenient, and quick, significantly reducing the workload of workers and improving marking efficiency.
