Description

Technical Field

[0002] Laser marking is a high-precision and high-efficiency marking device that plays an important role in modern manufacturing. It uses laser technology to perform fine marking on the surfaces of different materials. It is widely used in electronics, automobiles, medical devices, packaging and printing and other industries. The core of laser marking technology includes the generation of lasers, the conduction and focusing of light paths, and the physical or chemical changes on the surface of materials. Laser marking machines are favored for their non-contact processing, high speed, high precision and environmental protection characteristics.

[0003] Laser marking can be divided into two types: ordinary manual loading and marking one by one and large-scale rapid marking. Ordinary manual loading is usually used for small-scale component marking. Large-scale marking is completed by the stepping method of the conveyor belt and the dwell time of the stepping. This method can continuously mark the components.

[0037] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0038] like Figure 1-Figure 12 As shown, a mobile loading and unloading laser marking device is provided in the embodiment, which is used for high-precision laser marking of sheet materials or mechanical parts. A mobile loading and unloading laser marking device specifically comprises: a loading table 1, a laser marking machine 2 is arranged on the outer side of one end of the loading table 1, an unloading table 3 is arranged adjacent to the laser marking machine 2, a driving push rod 4 is arranged at the end of the loading table 1 away from the laser marking machine 2, the loading table 1 comprises a transmission seat 5 and a transfer plate 6, the transfer plate 6 is rotatably connected to the top surface of the transmission seat 5, the transfer plate 6 is located at the end of the transmission seat 5 close to the laser marking machine 2, the output end of the laser marking machine 2 is located directly above the transfer plate 6, and the output end of the driving push rod 4 is connected to the loading table 1. A push piece 7 and a driving strip 8 are provided, and the loading push piece 7 and the driving strip 8 slide on the inner side of the transmission seat 5. One end of the loading push piece 7 located inside the transmission seat 5 extends to the lower side of the bottom surface of the transfer disk 6. A lifting assembly 9 is provided below the top of one end of the loading push piece 7 located inside the transfer disk 6. The lifting assembly 9 is located on the inner side of the transmission seat 5. A unloading push piece 10 is provided on the side of the bottom surface of the transfer disk 6 away from the lifting assembly 9. One end of the driving strip 8 located inside the transmission seat 5 is drivingly connected to the unloading table 3, the transfer disk 6, the lifting assembly 9 and the unloading push piece 10.

[0039] The present invention provides a mobile loading and unloading laser marking device, which can fully automatically move the sheet material 110 to the bottom of the laser marking machine 2 for high-precision marking, and accurately position each sheet material 110 during the marking process, so that the marking positions of all sheet materials 110 are exactly the same. During the marking process, the loading and unloading can be automatically positioned to ensure that the material is in a synchronized and neat shape after marking, which is convenient for material collection.

[0040] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0041] Example 1

[0042] like Figure 1-Figure 12 As shown, a mobile loading and unloading laser marking device is provided, wherein a transfer disk 6 is provided with annular equidistantly distributed positioning transfer grooves 61, the bottom surface of the positioning transfer grooves 61 is located directly above the top material assembly 9, and a feeding port 62 is provided on the side of the positioning transfer grooves 61 close to the loading push piece 7, and a transfer ratchet gear 63 is fixed at the center of the bottom surface of the transfer disk 6, and the transfer ratchet gear 63 is meshed with the drive bar 8 for transmission.

[0043] A top material transmission cavity 501 is provided at the position where the transmission seat 5 is connected to the top material component 9, the transmission end of the top material component 9 is located inside the top material transmission cavity 501, and a top material lifting groove 502 is provided at the top of the top material transmission cavity 501, which is located directly below the positioning transfer groove 61. The output end of the top material component 9 slides inside the top material lifting groove 502, and the top surface of the transmission seat 5 is located directly below the feed port 62 and is provided with a feed slide 503, one end of the feed slide 503 is connected with one side of the top material lifting groove 502, the sheet material 110 slides inside the feed slide 503, and a drive hole 504 is provided on one side of the feed slide 503, the drive bar 8 is slidably penetrated inside the drive hole 504, one side of the transfer ratchet gear 63 is located inside the drive hole 504, and the side of the transfer ratchet gear 63 located inside the drive hole 504 is meshed with the drive bar 8 for transmission.

[0044] The positioning transfer groove 61 opened inside the transfer disk 6 can accurately limit the material and drive the material to position, rotate and slide. The feed port 62 below the positioning transfer groove 61 can limit the material during the material's advancement and sliding process, allowing the material to accurately slide into the bottom of the positioning transfer groove 61. The transfer ratchet gear 63 can make the drive bar 8 drive the transfer disk 6 in only one direction.

[0045] The setting of the top material transmission chamber 501 allows the top material component 9 to be driven directly below the positioning transfer groove 61, and pushes the material sliding to the bottom of the positioning transfer groove 61 toward the inner side of the positioning transfer groove 61, so that the material can completely enter the inner side of the positioning transfer groove 61. The top material lifting groove 502 can allow the output end of the top material component 9 to be limited and vertically lifted on the inner side. The setting of the feed slide 503 cooperates with the feed port 62 to form a sliding space with the same thickness as the material, so that the material can enter the bottom of the positioning transfer groove 61. The opening of the drive hole 504 can allow the drive bar 8 to slide on the inner side of the transmission seat 5 and complete the meshing drive of the transfer disk 6 and the top material component 9.

[0046] It should be noted that after the material passes through the combined feed port 62 and enters the bottom of the top transfer groove, the end of the material will abut against the inner wall of the top material lifting groove 502. At this time, the top material assembly 9 is driven to push the material upward, and the material can enter the inner side of the positioning transfer groove 61. When the positioning transfer groove 61 rotates, it will not apply shear force to the material to damage the material, thereby ensuring that the material can be moved accurately and safely.

[0047] Further, such as Figure 1-12As shown, the loading push piece 7 includes a push plate 71 inside, one end of the push plate 71 is in contact with the side of the sheet material 110, and the other end of the push plate 71 is connected to a telescopic plate 72 on the inner side for limiting sliding. A lifting plate 73 is provided on one side of the telescopic plate 72, and the lifting plate 73 is in contact with and slides on the outer surface of the push plate 71. A return spring 74 is provided inside the push plate 71, and one end of the return spring 74 is elastically connected to the outer wall of the telescopic plate 72.

[0048] The pushing plate 71 inside the loading pushing piece 7 can push the material so that the material can stably slide on the inside of the feeding port 62 and the feeding slide 503 and enter the bottom of the positioning transfer groove 61. The telescopic plate 72 can shrink the length of the loading pushing piece 7 after the pushing plate 71 pushes the material to the bottom of the positioning transfer groove 61. While ensuring that the sheet material 110 is accurately fixed inside the positioning transfer groove 61, the synchronous transmission driving bar 8 can apply driving force to the lifting assembly 9, completing the lifting of the material after the material is pushed and the transfer of the material after the transfer plate 6 moves up.

[0049] The lifting plate 73 on one side of the telescopic plate 72 can use its own thickness to support the material after the pushing plate 71 pushes the sheet material 110, preventing the sheet material 110 from sliding to the lower side and getting stuck on the surface of the loading push piece 7, thereby ensuring the driving stability of the structure; the reset spring 74 can push the retracted telescopic plate 72 outward, so that the loading push piece 7 can always maintain a sufficient pushing length.

[0050] When the feeding push piece 7 moves, the sheet material 110 located inside the feeding port 62 will be pushed by the pushing plate 71, and then the sheet material 110 will slide through the feeding port 62 to the inside of the ejecting lifting groove 502, at which time the telescopic plate 72 will be retracted into the inner side of the pushing plate 71, and then with the pushing of the feeding push piece 7, the driving bar 8 will drive the ejecting assembly 9 to start, and push the clamped sheet material 110 upward, so that the sheet material 110 is separated from the ejecting lifting groove 502, and then with the continued advancement of the feeding push piece 7, the driving bar 8 will drive the transfer disk 6 to rotate, and transfer the sheet material 110, and with the resetting of the feeding push piece 7, the length of the pushing plate 71 will be reset, and the ejecting assembly 9 will also be reset, and then the sheet material 110 will be continuously pushed and fed according to the above steps.

[0051] Example 2

[0052] The mobile loading and unloading laser marking device provided in Example 1 is further optimized. Specifically, Figure 1-Figure 12The top material assembly 9 includes a transmission gear rod 91 inside, which rotates horizontally on one side of the transmission seat 5 near the transfer ratchet gear 63. One end of the transmission gear rod 91 is located at the bottom inner side of the driving hole 504, and the transmission gear rod 91 is meshed with the driving bar 8 for transmission, and one side of the transfer ratchet gear 63 is meshed with the driving bar 8 for transmission. A top material bent rod 92 is connected to the center of the end face of the other side of the transmission gear rod 91, and the distal end of the top material bent rod 92 is rotatably connected to the inner wall of the top material transmission cavity 501. The outer side of the top material bent rod 92 is sleeved with equidistantly distributed piston rods 93, and the distal end of the piston rod 93 is hinged with a push rod 94. The outer surface of the push rod 94 slides vertically within the transmission seat 5, and the top of the push rod 94 is connected to a push material platform 95, which slides within the push material lifting groove 502.

[0053] The ejection assembly 9 can drive the ejection bent rod 92 to rotate through the transmission gear rod 91, driving the piston rod 93 to move upward, so that the ejection rod 94 connected to the end of the piston rod 93 can vertically push the ejection platform 95 upward, complete the upward propulsion of the material, and complete the complete embedding of the material into the positioning transfer groove 61.

[0054] Further, such as Figure 1-12 As shown, a section of the outer surface of the driving bar 8 located inside the driving hole 504 is fixed with equidistantly arranged transfer driving teeth 81, and the transfer driving teeth 81 are fixed to a side of the driving bar 8 close to the transfer ratchet gear 63, and the transfer driving teeth 81 are meshed with the transfer ratchet gear 63. The bottom surface of the driving bar 8 where the transfer driving teeth 81 are connected is fixed with equidistantly arranged top material driving teeth 82, and the top material driving teeth 82 are located at the front end of the transfer driving teeth 81, and the top material driving teeth 82 are meshed with the transmission gear rod 91. A unloading driving rod 83 is connected to one side of the middle part of one end of the driving bar 8 away from the top material driving teeth 82, and the distal end of the unloading driving rod 83 is fixedly transmitted to the unloading push piece 10, and a unloading driving tooth plate 84 is fixed to the end of the unloading driving rod 83 connected to the unloading push piece 10 close to the unloading table 3, and the unloading driving tooth plate 84 is meshed with the unloading table 3 for transmission.

[0055] When the ejection assembly 9 is working, the ejection driving teeth 82 connected to the outer surface of the driving bar 8 are meshed with the transmission gear rod 91. The movement of the driving bar 8 drives the transmission gear rod 91 to rotate, and then the ejection bent rod 92 connected to the transmission gear rod 91 will rotate, and the rotation and lifting driving principle of the bent rod will be used to drive the ejection platform 95 to push the sheet material 110 upward. When the ejection bent rod 92 drives the ejection platform 95 to move upward and pushes the material to the upper part and separates it from the ejection lifting groove 502, the transfer driving teeth 81 connected to the outer wall of the driving bar 8 will engage with the transfer ratchet gear 63, driving the transfer disk 6 to rotate, so that the transfer disk 6 drives the sheet material 110 to complete the movement.

[0056] When the driving bar 8 is reset, the ejecting driving tooth 82 will drive the ejecting assembly 9 to reset. Since a transfer ratchet gear 63 is used under the transfer disk 6, the transfer driving tooth 81 will only drive the gear outside the transfer ratchet gear 63 to rotate, and the internal ratchet will slide with the gear.

[0057] Example 3

[0058] The mobile loading and unloading laser marking device provided in Example 1 is further optimized. Specifically, Figure 1-Figure 12 A push piece movable groove 102 is provided at the position where the transmission seat 5 is connected to the unloading push piece 10, and a unloading groove opening 101 is provided on one side of the push piece movable groove 102 directly below the positioning transfer groove 61, and the unloading push piece 10 slides inside the push piece movable groove 102, and one end of the unloading push piece 10 slides on the inner surface of the unloading groove opening 101, and a crawler material receiving groove 103 is provided on the side of the unloading groove opening 101 away from the push piece movable groove 102, and one end of the unloading platform 3 is fixed on the inner side of the crawler material receiving groove 103.

[0059] The push-piece movable groove 102 provides sufficient sliding space for the sliding of the unloading push piece 10, so that the unloading push piece 10 has sufficient storage space when preparing to push the sheet material 110. The unloading groove 101 allows the sheet material 110 to fall to the inside after being marked, driven by the stepping rotation of the transfer disk 6, so as to complete the separation of the sheet material 110 and the positioning transfer groove 61. At the same time, after falling, the sheet material 110 can be pushed forward by the unloading push piece 10 to complete the sliding unloading of the sheet material 110 and move to the inside of the crawler receiving groove 103.

[0060] Further, such as Figure 1-12 As shown, the unloading platform 3 includes a driving roller 31, both ends of which are rotatably connected to the inner wall of the crawler receiving groove 103, a conveyor belt 32 is sleeved on the outside of the driving roller 31, the far end of the conveyor belt 32 is located on the outside of the transmission seat 5, and the top surface of the conveyor belt 32 is located below the bottom surface of the unloading groove 101, and one end of the driving roller 31 that is rotatably connected to the inner wall of the crawler receiving groove 103 is fixed with a driven bevel gear 33, and the inside of the transmission seat 5 is located on one side of the driven bevel gear 33 and is rotatably connected with a transmission bevel gear 34 in a vertical direction, the transmission bevel gear 34 is meshed with the driven bevel gear 33, and a transmission ratchet gear 35 is connected below the transmission bevel gear 34, and the transmission ratchet gear 35 is meshed with the unloading drive tooth plate 84 for transmission.

[0061] The setting of the unloading platform 3 inside the crawler receiving trough 103 allows the sheet material 110 pushed by the unloading push piece 10 to slide accurately onto the conveyor belt 32, and then as the unloading drive rod 83 contracts and pulls, the unloading platform 3 is driven to complete the unloading and conveying of the sheet material 110.

[0062] The unloading table 3 is driven by the unloading driving rod 83 to push the unloading push piece 10, and the unloading driving tooth plate 84 is used to drive the rotation of the transmission ratchet gear 35, driving the transmission bevel gear 34 to engage with the driven bevel gear 33 for transmission, driving the driving roller 31 to rotate, and completing the movement of the conveyor belt 32. Since the unloading driving rod 83 is reciprocatingly pushed, the conveyor belt 32 lifted by the unloading will drive the sheet material 110 to be transported to the outside in a stepping manner.

[0063] It should be noted that the transmission ratchet gear 35 can only receive the one-way driving force of the unloading drive rod 83, so the unloading table 3 can only transport the sheet material 110 to the outside. Due to the setting of the transmission ratchet gear 35, the two-way driving force of the unloading drive rod 83 will drive the gear outside the transmission ratchet gear 35 to rotate, and the gear will slide with the internal ratchet.

[0064] When the unloading drive rod 83 is pushed forward in a single stroke, it will drive the unloading platform 3, and will not drive the unloading platform 3 to move during the return stroke. However, during the return stroke, the unloading drive rod 83 will drive the unloading push piece 10 to push the sheet material 110, and push the sheet material 110 to the upper part of the conveyor belt 32 inside the unloading lift, thereby completing a stable progressive unloading structure.

[0065] Example 4

[0066] A mobile loading and unloading laser marking device provided in Example 1, 2 or 3 is further optimized, specifically, as follows: Figure 1-Figure 12 As shown, a loading rack 11 is provided on the top surface of the loading platform 1 at the output end of the loading push piece 7, and the lower part of the center of the loading rack 11 is connected to the front of the loading push piece 7, and a sheet material 110 is provided inside the loading rack 11, and the end of the loading rack 11 slides on the inner surface of the loading rack 11, and a loading seat 12 is provided on one side of the loading rack 11, and the loading seat 12 is transmission-connected to the output end of the driving push rod 4, and a rotating table 121 is rotatably connected to the top surface of the loading seat 12, and a material picking rod 122 is connected to the top of the rotating table 121, and a material picking push rod 123 is vertically fixed to the far end of the material picking rod 122, and a material picking suction cup 124 is connected to the bottom output end of the material picking push rod 123, and a double pump assembly 125 is fixed to the middle of the top surface of the material picking rod 122, and an exhaust pipe 126 is connected to the output end of the double pump assembly 125, and the other end of the exhaust pipe 126 is connected to the inside of the material picking suction cup 124.

[0067] A driving rack 41 is connected to one side of the output end of the driving push rod 4, and a transmission gear 42 is provided on one side of the feeding push piece 7 connected to the driving push rod 4. The transmission gear 42 meshes with the driving rack 41 for transmission, and a pulley 43 is connected to the top of the transmission gear 42. A transmission belt 44 is sleeved on the outside of the pulley 43, and the other end of the transmission belt 44 is sleeved on the outside of the rotating table 121. A driving rack 41 is connected to one side of the output end of the driving push rod 4, and a feeding push piece 7 is connected to one side of the driving push rod 4. The transmission gear 42 meshes with the driving rack 41 for transmission, and a pulley 43 is connected to the top of the transmission gear 42. A transmission belt 44 is sleeved on the outside of the pulley 43, and the other end of the transmission belt 44 is sleeved on the outside of the rotating table 121.

[0068] The loading rack 11 can sort and discharge the placed materials, ensuring that the materials can accurately fall into the inner side of the feed port 62 after being placed, and ensuring that the loading push piece 7 can accurately push each material stably.

[0069] A loading seat 12 is provided on one side of the loading rack 11. When the driving push rod 4 is started, the loading seat 12 can be driven to rotate, and the picking rod 122 on the upper part of the loading seat 12 can be driven to rotate, so that the picking rod 122 can be rotated 180° to the other side. Through the coordinated driving of the picking rod 122 and the double pump assembly 125, the sheet material 110 inside the conveyor belt 32 on one side or the loading platform 1 is adsorbed and fixed, and then the picking rod 122 is driven to rotate in the opposite direction and reset during the return process of the driving push rod 4, thereby completing the automatic loading of the sheet material 110.

[0070] When the driving push rod 4 is working, the driving rack 41 connected to one side of the output end of the driving push rod 4 will drive the transmission gear 42 to rotate, and the rotation of the transmission gear 42 will drive the pulley 43 to rotate, and the rotation of the pulley 43 will drive the transmission belt 44 to rotate, thereby transmitting the rotational force of the pulley 43 to the rotating table 121. When the rotating table 121 rotates, it will drive the material picking rod 122 to rotate, and when the material picking push rod 123 rotates, it will be transferred to the other side, and then the material picking push rod 123 will start to drive the material picking suction cup 124 to move downward, and when the material picking suction cup 124 is in contact with the sheet material 110, the vacuum pump inside the double pump assembly 125 will Start, the sheet material 110 is adsorbed by the material picking suction cup 124, and then the material picking push rod 123 moves up to move the sheet material 110 to a higher place. As the driving push rod 4 returns, the material picking rod 122 rotates, and the sheet material 110 moves to just above the loading rack 11. The material picking push rod 123 starts to move down and moves the sheet material 110 to the inside of the loading rack 11. The vacuum pump inside the double pump assembly 125 is turned off, and the air outlet pump is started to place the sheet material 110 on the inside of the loading rack 11. The material picking push rod 123 starts to move up, and the above steps can be continued to clamp and move the sheet material 110 to realize automatic loading.

[0071] It should be noted that the dual pump assembly 125 includes an air suction pump and an air outlet pump. The air suction pump can provide suction for the material picking suction cup 124 to stably adsorb and fix the sheet material 110, while the air outlet pump is an ordinary air pump that can spray air to the material picking suction cup 124 with suction to separate the material from the material picking suction cup 124.

[0072] The driving rack 41 is fully pushed out to drive the transmission gear 42 to rotate the tooth pitch, and after being transmitted through the pulley 43, it can just drive the rotating table 121 to rotate 180°, so that the driving bar 8 connected to the upper part of the rotating table 121 can rotate to the other side, and the sheet material 110 on the conveying table or conveying equipment on the other side is sucked and fixed. With the return stroke of the driving push rod 4, the material picking suction cup 124 will rotate to the center position just above the loading rack 11, and then the sucked material will be moved down to the inside of the loading rack 11.

[0073] The working principle of a mobile loading and unloading laser marking device provided by the present invention is that when the driving push rod 4 is started, it will simultaneously drive the loading push piece 7 and the driving bar 8 to advance, and the loading push piece 7 will push the sheet material 110 to slide to the inner side of the top material lifting groove 502 inside the transmission seat 5. At this time, the top material driving teeth 82 on the outer wall of the driving bar 8 will move to the position of the top material assembly 9. As the driving push rod 4 continues to advance, the loading push piece 7 will shrink, and the driving bar 8 will drive the top material assembly 9 to work through the top material driving teeth 82, pushing the sheet material 110 upward, and completely pushing the sheet material 110 into the positioning transfer groove 61. At this time, the transfer driving teeth 81 outside the driving bar 8 will engage with the transfer ratchet gear 63, driving the transfer disk 6 to rotate, thereby completing the conveying of the sheet material 110.

[0074] When the transfer disk 6 rotates, the sheet material 110 entering the positioning transfer groove 61 will be driven to the bottom of the laser marking machine 2. Since the driving push rod 4 takes time to return, the laser marking machine 2 will mark the sheet material 110 at this time. The marked sheet material 110 will rotate again and move to the top of the unloading groove 101. At this time, since the driving push rod 4 is pushed to the farthest position, the sheet material 110 will fall to the inside of the unloading groove 101. As the driving push rod 4 returns, the sheet material 110 that falls into the unloading groove 101 will be pushed, completing the function of moving the sheet material 110 to the inside of the unloading table 3.

[0075] When the sheet material 110 moves to the upper part of the conveyor belt 32 inside the unloading platform 3, the conveyor belt 32 of the unloading platform 3 is driven to move along with the advancement of the driving push rod 4, completing the unloading and conveying of the sheet material 110.

[0076] The transfer ratchet gear 63 and the transmission ratchet gear 35 of this embodiment have the function of one-way transmission. When the ratchet gear is subjected to reverse driving force, the outer wheel of the ratchet gear meshing with the meshing teeth will rotate, and the inner ratchet will slide, thereby realizing the function of one-way transmission. When rotating forward, the ratchet will mesh with the outer gear to drive.

[0077] Other technologies of this embodiment adopt existing technologies.

[0078] The present invention is described by preferred embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the claims of this application are within the scope of protection of the present invention.
