Description

Technical Field

[0001] The invention relates to the field of laser marking, in particular to a continuous laser marking machine for pipe production. Background Art

[0002] Laser marking of metal materials is to locally irradiate the metal material with laser light generated by a laser generator, causing the metal material to locally produce reactions such as oxidation, boiling and ablation, thereby achieving local removal of the metal material and adding identification to the metal material surface. In the pipe production process, it is necessary to add identification to the pipe surface through laser marking. Pipes installed in environments prone to friction and corrosion usually require laser marking to have a certain depth to facilitate the clear identification of the pipe surface.

[0003] During laser marking, a certain amount of smoke will be generated during the process of local oxidation, boiling and ablation of metal materials. Increasing the marking depth requires removing more metal materials, which will lead to more smoke generated during the laser marking process. Increased smoke will lead to more smoke adhesion on the surface of the pipe body. The existing laser marking device is not convenient for blocking the smoke generated by laser irradiation, resulting in more smoke adhering to the parts of the pipe surface that do not need laser marking. In addition, the existing laser marking device is not convenient for removing the smoke adhesion on the pipe surface, which reduces the aesthetics of the laser marking of the pipe. Summary of the Invention

[0017] More preferably, a friction ring is further included, and each limiting wheel is fixedly connected with a friction ring.

[0018] Compared with the prior art, the present invention has the following advantages: 1. The conveying wheel reverses to drive the pipe body to move, and the laser generator performs laser marking on other positions of the pipe body, thereby continuously laser marking the pipe body. The flat part of the bottom of the graphite felt contacts the pipe body. During the laser marking process, the laser generated by the laser generator passes through the through groove on the transmission belt and the limit groove on the graphite felt. The transmission belt and the flat part of the bottom of the graphite felt move synchronously with the pipe body. The flat part of the bottom of the graphite felt will block a small amount of smoke generated on the surface of the pipe body, thereby reducing the smoke adhesion in the area of ​​the pipe body surface that does not need to be marked, so that the surface of the pipe body is more tidy after marking is completed, thereby improving the aesthetics of the laser marking.

[0019] 2. The wiping block contacts the pipe body, and the conveying wheel reverses to drive the pipe body to move. The wiping block wipes the surface of the marked area of ​​the pipe body, thereby wiping and removing part of the smoke attached to the surface of the marked area of ​​the pipe body. When the swing frame contacts the transmission belt, the transmission belt continues to rotate clockwise to squeeze the swing frame and the wiping block to swing upward. The transmission belt continues to rotate clockwise again, and the transmission belt separates from the swing frame. The torsion spring rebounds and resets to drive the swing frame and the wiping block to swing downward and reset. The wiping block contacts the pipe body again, and the wiping block continues to wipe and remove part of the smoke attached to the surface of the marked area of ​​the pipe body. In this way, part of the smoke attached to the surface of the marked area of ​​the pipe body is continuously wiped and removed, further improving the aesthetics of the laser marking.

[0020] 3. When the swing frame contacts the transmission belt, the transmission belt continues to rotate clockwise to squeeze the swing frame and the wiping block to swing upward, the separation ring is separated from the upper end of the guide groove on the swing frame, and the liquid in the storage frame flows downward through the separation ring and the guide groove on the swing frame. The wiping block absorbs the cleaning agent flowing out of the guide groove on the swing frame, and then the transmission belt is separated from the swing frame. The torsion spring rebounds and resets to drive the swing frame and the wiping block to swing downward and reset. The wiping block that absorbs the cleaning agent wipes and removes part of the smoke attached to the surface of the pipe body where the marking is completed, which can more fully remove the smoke attached to the surface of the pipe body and further improve the aesthetics of the laser marking.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1: A continuous laser marking machine for pipe production, such as Figure 1-Figure 7 Shown, including:

[0033] Base 1;

[0034] The mounting frame 2 is connected to the base 1 by bolts;

[0035] Two servo motors 3 are connected to the mounting frame 2 by bolts;

[0036] Two conveying wheels 4 are rotatably connected to the lower part of the mounting frame 2. The output shaft of the servo motor 3 is fixedly connected to the conveying wheels 4. The pipe body 5 is placed on the two conveying wheels 4.

[0037] A marking assembly is provided on the mounting frame 2 and is used to perform laser marking on the pipe body 5;

[0038] The limiting assembly is provided on the base 1 and is used to provide limiting support for the pipe body 5 .

[0039] The marking assembly includes: a support rail 62, welded to the lower part of the mounting frame 2; a laser generator 63, slidingly connected to the upper part of the support rail 62; a support rod 64, welded to the middle part of the mounting frame 2; a partition frame 65, connected to the support rod 64 by bolts, and an exhaust port is provided on the partition frame 65; an air pump 66, connected to the support rod 64 by bolts, the partition frame 65 is fixed to the air pump 66, and the exhaust port on the partition frame 65 is connected to the air pump 66.

[0040] The limiting assembly includes: two limiting brackets 71, which are connected to the base 1 by bolts; four groups of limiting wheels 72 are rotatably connected to the two limiting brackets 71, and each group of limiting wheels 72 has five; a feeding frame 73, which is welded to one side of one of the limiting brackets 71.

[0041] At first, the worker starts the servo motor 3, the laser generator 63 and the vacuum pump 66, and puts the pipe body 5 through the feed frame 73, so that the limiting wheel 72 on one of the limiting brackets 71 limits the pipe body 5, so that the two conveying wheels 4 are in contact with the pipe body 5, and then the output shaft of the servo motor 3 is reversed to drive the conveying wheel 4 to reverse, and the conveying wheel 4 is reversed to drive the pipe body 5 to move, so that the pipe body 5 contacts the limiting wheel 72 on the other limiting bracket 71, and the limiting wheel 72 on the other limiting bracket 71 limits the pipe body 5. During the movement of the pipe body 5, the laser generator 63 intermittently performs laser marking on the surface of the pipe body 5. During the laser marking process, the surface of the pipe body 5 Local heating causes oxidation, boiling, ablation and other reactions to occur locally on the surface of the pipe body 5, and a small amount of smoke is generated on the surface of the pipe body 5, thereby removing part of the metal material on the surface of the pipe body 5 and adding a mark on the surface of the pipe body 5. The vacuum pump 66 sucks a small amount of smoke, allowing a small amount of smoke to pass through the exhaust port on the partition frame 65 and then be discharged through the vacuum pump 66. The worker collects and processes the small amount of smoke discharged by the vacuum pump 66, and then the conveying wheel 4 continues to reverse to drive the pipe body 5 to move, and the laser generator 63 performs laser marking on other positions of the pipe body 5, thereby continuously laser marking the pipe body 5. When the pipe body 5 is separated from the conveying wheel 4, the marking on the surface of the pipe body 5 is completed.

[0042] Example 2: Based on Example 1, Figure 1 and Figure 5As shown, it also includes a fitting component, which is arranged on the mounting frame 2, and the fitting component is used to fit the pipe body 5. The fitting component includes: a large transmission wheel 81, which is rotatably connected to the upper part of the mounting frame 2; two small transmission wheels 82, which are rotatably connected to the middle part of the mounting frame 2; a transmission belt 83 is wound around the large transmission wheel 81 and the two small transmission wheels 82, and a plurality of through grooves are opened on the transmission belt 83; a graphite felt 84 is fixed to the outside of the transmission belt 83, and a plurality of limiting grooves are opened on the graphite felt 84, and the through grooves on the transmission belt 83 are aligned with the limiting grooves on the graphite felt 84; a support seat 85, which is welded to the mounting frame 2; a rotating shaft 86, which is rotatably connected to the support seat 85; a bevel gear 1 87, which is connected to one end of the large transmission wheel 81 through a flat key; a bevel gear 2 88, which is connected to the upper end of the rotating shaft 86 through a flat key; a bevel gear 3 89, which is connected to one end of one of the conveying wheels 4 through a flat key; and a bevel gear 4 810, which is connected to the lower end of the rotating shaft 86 through a flat key.

[0043] When the two conveying wheels 4 are in contact with the pipe body 5, the flat bottom portion of the graphite felt 84 is in contact with the pipe body 5. During the laser marking process, the laser generated by the laser generator 63 passes through the through slot on the transmission belt 83 and the limit slot on the graphite felt 84. When the output shaft of the servo motor 3 reverses to drive the conveying wheels 4 in the reverse direction, the conveying wheels 4 reversely drive the large transmission wheel 81 to rotate clockwise through the rotating shaft 86, bevel gear 1 87, bevel gear 2 88, bevel gear 3 89 and bevel gear 4 810. The large transmission wheel 81 rotates clockwise, driving the transmission belt 83 and the graphite felt 84 to rotate clockwise. The transmission belt 83 rotates clockwise to drive the small transmission wheel 82 to rotate clockwise, so that the large transmission wheel 81 and the conveying wheel 4 rotate synchronously. During the clockwise rotation of the transmission belt 83 and the graphite felt 84, the straight bottom parts of the transmission belt 83 and the graphite felt 84 move synchronously with the pipe body 5. During the laser marking process, the straight bottom part of the graphite felt 84 will block a small amount of smoke generated on the surface of the pipe body 5, thereby reducing the adhesion of smoke to the area on the surface of the pipe body 5 that does not need to be marked, making the surface of the pipe body 5 neater after marking, thereby improving the aesthetics of the laser marking.

[0044] Example 3: Based on Example 2, Figure 6-Figure 8 As shown, it also includes an erasing component, which is arranged on the marking component. The erasing component is used to erase attachments on the surface of the pipe body 5. The erasing component includes: a support block 91, which is connected to the upper part of the partition frame 65 by bolts; a swing frame 92, which is rotatably connected to the support block 91, and a guide groove is provided on the swing frame 92; two torsion springs 93 are connected between the swing frame 92 and the support block 91 by hooks; a wiping block 95, which is fixed to the lower part of the swing frame 92, and the wiping block 95 is located below the guide groove on the swing frame 92.

[0045] When the two conveying wheels 4 contact the pipe body 5, the swing frame 92 separates from the transmission belt 83, the wiping block 95 contacts the pipe body 5, the conveying wheel 4 reverses to drive the pipe body 5 to move, and the wiping block 95 wipes the surface of the area where the marking is completed on the pipe body 5, thereby wiping and removing part of the smoke attached to the surface of the area where the marking is completed on the pipe body 5. When the swing frame 92 contacts the transmission belt 83, the transmission belt 83 continues to rotate clockwise to squeeze the swing frame 92 and the wiping block 95 to swing upward, the wiping block 95 separates from the pipe body 5, the torsion spring 93 is twisted, the transmission belt 83 continues to rotate clockwise, the transmission belt 83 separates from the swing frame 92, the torsion spring 93 rebounds and resets, driving the swing frame 92 and the wiping block 95 to swing downward and reset, the wiping block 95 contacts the pipe body 5 again, and the wiping block 95 continues to wipe and remove part of the smoke attached to the surface of the area where the marking is completed on the pipe body 5, thereby continuously wiping and removing part of the smoke attached to the surface of the area where the marking is completed on the pipe body 5, further improving the aesthetics of the laser marking.

[0046] Example 4: Based on Example 3, Figure 6-Figure 9 As shown, it also includes an auxiliary wiping component, which is arranged on the marking component. The auxiliary wiping component is connected to the erasing component. The auxiliary wiping component is used to assist in wiping the surface of the pipe body 5. The auxiliary wiping component includes: a separating ring 901, which is rotatably connected to the upper end of the swing frame 92; a liquid storage frame 902, which is connected to the upper part of the separating frame 65 by bolts, and the lower part of the liquid storage frame 902 is fixedly connected to the separating ring 901. A discharge outlet is provided at the bottom inner side of the liquid storage frame 902, and the discharge outlet on the liquid storage frame 902 is connected to the separating ring 901.

[0047] 83, the wiping block 95 is rotated to remove the cleaning agent from the surface of the pipe body 5.

[0048] Example 5: Based on Example 4, Figure 1 and Figure 4As shown, a friction ring 10 is also included. Each limiting wheel 72 is fixed with a friction ring 10, and the friction ring 10 is used to limit the rotation of the pipe body 5.

[0049] When the limiting wheel 72 on the limiting bracket 71 supports the pipe body 5, the friction ring 10 contacts the pipe body 5. The friction between the friction ring 10 and the pipe body 5 can limit the rotation of the pipe body 5, thereby reducing the rotation of the pipe body 5 during the movement of the pipe body 5, thereby more stably performing laser marking on the pipe body 5.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
