Description

Technical Field

[0001] The present invention relates to the field of laser cutting equipment, in particular to a laser cutting equipment for anti-counterfeiting printing. Background Art

[0002] An anti-counterfeiting label is a mark that can be pasted, printed, or transferred to the surface of an object, its packaging, or its accessories. It has anti-counterfeiting features and identification methods. By adopting specific anti-counterfeiting technology, consumers can easily identify the authenticity of the product.

[0003] Steel is widely used in many fields, including construction, machinery manufacturing, and automobile manufacturing. Steel is often valuable and easily targeted by counterfeiters. Printing anti-counterfeiting labels can effectively prevent steel products from being counterfeited, protecting a company's economic interests and market position.

[0004] Laser cutting equipment is required when printing anti-counterfeiting labels on steel. Laser cutting equipment can achieve high-precision cutting and engraving, and can process tiny, fine and complex patterns and texts on the surface of steel. These patterns and texts are difficult to imitate, thereby improving the anti-counterfeiting performance of the anti-counterfeiting label.

[0005] In the prior art, due to the high reflectivity of steel, printing on steel requires that it be done in a closed and dark environment to reduce the reflectivity of the steel. However, in this environment, the dust generated by the laser cutting equipment during printing is difficult to be discharged. Although dust collection equipment can be used for adsorption in the prior art, if the dust is not completely absorbed and the steel is easily adhered to dust during transportation, especially when the anti-counterfeiting labels are printed at different locations on different steels, if the dust on the steel is not cleaned in time, it will cause interference such as reflection and scattering on the laser, so that the laser cannot completely follow the predetermined path and energy distribution. Acting on the surface of steel, it reduces the effective utilization rate of the laser, resulting in uneven edges of printed patterns or texts, reduced accuracy, and even missing or blurred patterns. If the dust suction device is directly set at the position of the laser head, although it can effectively remove dust from the printing position, the dust suction head is close to the printing position. It is not only affected by the high temperature of the laser head and easily damaged, but also interferes with the normal flow and covering effect of the protective gas, causing oxygen, nitrogen, etc. in the air to mix into the area printed by the laser head, resulting in defects such as pores and inclusions, reducing the accuracy of the printed anti-counterfeiting mark, and the processing effect is poor if the distance is far.

[0006] Therefore, a laser cutting device for anti-counterfeiting printing is proposed. Summary of the Invention

[0007] In view of the above or the existing technology, although the dust suction equipment can be used for adsorption, if the dust is not completely absorbed and the steel is easily adhered to dust during the transportation process, especially the positions of anti-counterfeiting labels printed on different steels are different, if the dust on the steel is not cleaned in time, it will cause reflection, scattering and other interference to the laser, so that the laser cannot act on the steel surface completely according to the predetermined path and energy distribution, reducing the effective utilization rate of the laser, resulting in uneven edges of printed patterns or texts, reduced accuracy, and even missing or blurred patterns. If the dust suction device is directly set at the position of the laser head, although the printing position can be effectively removed, the dust suction head is close to the printing position, not only affected by the high temperature of the laser head and easily damaged, but also interferes with the normal flow and covering effect of the protective gas, so that oxygen, nitrogen, etc. in the air are mixed into the area printed by the laser head, resulting in defects such as pores and inclusions, reducing the accuracy of the printed anti-counterfeiting mark, and the processing effect is poor if the distance is far.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Example 1, reference Figures 1 to 5 , which is the first embodiment of the present invention, provides a laser cutting device for anti-counterfeiting printing, which can achieve the effect of printing anti-counterfeiting marks on steel, and includes a cutting mechanism 1, which includes a frame 11, a slide rail 12 is installed on the frame 11, a first slider 13 is installed on the slide rail 12, a laser assembly 14 and an air box 15 are installed on the first slider 13, a first conduit 111 is connected to the air box 15, an end of the first conduit 111 away from the air box 15 is connected to an air pump 16, a nozzle 17 is connected to the air pump 16, and the first slider 13 is away from the nozzle A dust collection assembly 18 is provided at the top of one end of 17, and a second conduit 19 is connected to the dust collection assembly 18. The end of the second conduit 19 away from the dust collection assembly 18 is connected to the dust collection head 110. A dust removal mechanism 2 is installed on the top of the first slider 13. The dust removal mechanism 2 includes a driving assembly 21 provided on the first slider 13. The driving assembly 21 is connected to a switching assembly 22 for switching the gas sprayed by the nozzle 17. The switching assembly 22 is connected to the air pump 16 through a third conduit 23. A sliding assembly 24 for controlling the movement of the dust collection head 110 is provided on the first slider 13;

[0032] Among them, the laser assembly 14 and the dust collection assembly 18 are very mature existing technologies and will not be described in detail here;

[0033] The end of the third conduit 23 away from the nozzle 17 is provided with a filter, so that the air extracted by the nozzle 17 through the third conduit 23 is relatively clean air, thereby improving the treatment effect on the steel.

[0034] By setting the driving component 21, the switching component 22 and the sliding component 24 can be driven to operate. In the initial state, the driving component 21 can first drive the third conduit 23 to spray air and the dust suction head 110 to approach the place where the anti-counterfeiting label needs to be printed. The air pump 16 draws air through the third conduit 23 to blow air to the place where the anti-counterfeiting label needs to be printed, and blows away the dust at the place where the anti-counterfeiting label needs to be printed. At the same time, when blowing air, the dust is directly absorbed by the dust suction head 110, avoiding the problem of dust scattering and affecting the laser emitted by the laser cutting equipment. At the same time, when cleaning is completed, the driving component 21 continues to drive the switching component 22 and the sliding component 24 to operate. At this time, the dust collector head 110 automatically resets, so that the dust collector head 110 is away from the laser assembly 14, so that when the laser assembly 14 performs anti-counterfeiting printing on steel, the dust collector head 110 will not be too close to the laser head, thereby affecting the laser equipment laser assembly 14 to print anti-counterfeiting labels on the surface of steel. At the same time, it also avoids the problem of the high temperature of the laser head affecting the dust collector head 110. During laser printing, the protective gas inside the protective gas box 15 can be sprayed to the printing area through the first conduit 111 and the nozzle 17, which ensures the printing accuracy. At the same time, the generated debris can be directly absorbed by the dust collector head 110.

[0035] In this embodiment, a conventional laser printing device is provided. When the steel to be printed is transported to the appropriate position, the first slider 13 is driven to move by the slide rail 12, so that the first slider 13 drives the laser assembly 14 to move to the appropriate position, and then the air pump 16 is turned on. The air pump 16 extracts the protective gas inside the air box 15 through the first conduit 111, and sprays it on the laser emission point through the nozzle 17, so that the laser assembly 14 prints the anti-counterfeiting mark on the steel, and the dust collection assembly 18 absorbs the dust generated during the printing process through the second conduit 19 and the dust collection head 110.

[0036] Example 2, reference Figures 1 to 5, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a laser cutting device for anti-counterfeiting printing, which can achieve the effect of cleaning the area where printing is required. The driving assembly 21 includes a cylinder 211 fixedly installed on the top of the first slider 13, and the output end of the cylinder 211 is fixedly connected to the support block 212. One side of the support block 212 is fixedly connected to the first cross plate 213. A second slider 214 is provided on the top of the first slider 13, and a first inclined groove 215 is opened on the second slider 214. The end of the first cross plate 213 away from the support block 212 extends to the inside of the first inclined groove 215 and is fixedly connected to the first driving block 216.

[0037] Furthermore, the switching assembly 22 includes a limit plate 221 connected to the bottom of the second slider 214, and a through opening 222 is opened on the limit plate 221. The first conduit 111 and the third conduit 23 are both provided with a notch 223, and the notch 223 matches the limit plate 221. In the initial state, the limit plate 221 blocks the notch 223 of the first conduit 111 and the third conduit 23. As the limit plate 221 moves, the through opening 222 of the limit plate 221 corresponds to the positions of the two notches 223 in turn, so that the nozzle 17 can spray different gases.

[0038] Furthermore, the driving assembly 21 also includes a second horizontal plate 217 connected to the side of the support block 212 away from the second slider 214, a third slider 218 is provided on the top of the first slider 13, the third slider 218 is located on the side of the support block 212 away from the second slider 214, a second inclined groove 219 is provided on the third slider 218, the side of the second horizontal plate 217 away from the support block 212 extends to the inside of the second inclined groove 219 and is connected to the second driving block 2110, and the bottom of the third slider 218 is connected to the third driving block 2111.

[0039] Furthermore, a concave frame 131 is installed on the top of the first slider 13, and an auxiliary groove 132 is opened on the concave frame 131. Two auxiliary blocks 133 are slidingly arranged inside the auxiliary groove 132. One end of the two auxiliary blocks 133 passes through the auxiliary groove 132 and is fixedly connected to the second slider 214 and the third slider 218 respectively. The setting of the auxiliary groove 132 and the two auxiliary blocks 133 ensures that the second slider 214 and the third slider 218 can only move in a straight line, which facilitates the second slider 214 to drive the limit plate 221 to switch the gas ejected by the nozzle 17, and the third slider 218 drives the vacuum cleaner head 110 to move through the sliding assembly 24.

[0040] Furthermore, the sliding assembly 24 includes a fixed plate 241 provided on the top of the first slider 13, and the side of the fixed plate 241 close to the support block 212 is connected to the telescopic rod 242, and a first spring 243 is provided inside the telescopic rod 242. The first spring 243 is used to reset the extended end of the telescopic rod 242, and to form a certain buffer when the extended end of the telescopic rod 242 is reset. One end of the first spring 243 is fixedly connected to the inner wall of the telescopic rod 242, and the other end of the telescopic rod 242 is connected to the extended end of the telescopic rod 242. The end of the telescopic rod 242 away from the fixed plate 241 is connected to the fourth slider 244, and the fourth slider 244 is connected to the vacuum cleaner head 110 through the support rod 245.

[0041] Furthermore, the sliding assembly 24 also includes a fifth slider 246 arranged on the fourth slider 244, a first plane 247 is provided on the fifth slider 246, and a second plane 248 is provided on the third driving block 2111. The positions of the first plane 247 and the second plane 248 correspond to each other, so that when the third driving block 2111 moves, it can squeeze the first plane 247 on the fifth slider 246 through the second plane 248, thereby driving the fifth slider 246 to move.

[0042] Furthermore, the sliding assembly 24 also includes a groove 249 opened on the fourth slider 244, and the end of the fifth slider 246 away from the third slider 218 extends into the interior of the groove 249 and is connected to a second spring 2410, and the end of the second spring 2410 away from the fifth slider 246 is fixedly connected to the bottom inner wall of the groove 249.

[0043] Furthermore, the sliding assembly 24 also includes a first inclined surface 2411 provided on the fifth slider 246 , a limiting frame 2412 is installed on the top of the first slider 13 , a second inclined surface 2413 is provided on the limiting frame 2412 , and a third inclined surface 2414 is provided on the third driving block 2111 .

[0044] Furthermore, the drive assembly 21 also includes a vertical groove 2112 provided on the third slider 218. The setting of the vertical groove 2112 enables, when the second drive block 2110 is located at the connection point between the second inclined groove 219 and the vertical groove 2112, the second drive block 2110 continues to rise and move inside the vertical groove 2112, and no longer drives the third slider 218 to move, thereby reducing wear.

[0045] The rest of the structure is the same as that of Example 1.

[0046] When it is necessary to print an anti-counterfeiting label on steel, the cylinder 211 is turned on, and the cylinder 211 drives the supporting block 212 to rise, and the supporting block 212 drives the first transverse plate 213 and the second transverse plate 217 connected thereto to rise, and the first transverse plate 213 and the second transverse plate 217 drive the first driving block 216 and the second driving block 2110 connected thereto to rise, so that the first driving block 216 and the second driving block 2110 respectively squeeze the groove surface of the first inclined groove 215 and the groove surface of the second inclined groove 219 on the second slider 214 and the third slider 218, thereby making the second slider 214 and the third slider 218 approach each other; when the second slider 214 approaches, it drives the limiting plate 221 to move, so that the opening 222 on the limiting plate 221 corresponds to the position of the notch 223 on the third conduit 23, so that the nozzle 17 can inhale the outside air through the third conduit 23 and the opening 222, and spray it to the place where the anti-counterfeiting label needs to be printed through the nozzle 17, so as to remove dust from the printed anti-counterfeiting label;

[0047] The third slider 218 drives the third driving block 2111 to move, and the third driving block 2111 squeezes the first flat surface 247 on the fifth slider 246 through the second flat surface 248 thereon, thereby causing the fifth slider 246 to move toward the laser assembly 14. The fifth slider 246 drives the fourth slider 244 to move, and the fourth slider 244 drives the extended end of the telescopic rod 242 to pass through the barrel. The extended end of the telescopic rod 242 drives the second spring 2410 to lengthen. At the same time, the fourth slider 244 drives the dust collection head 110 to move toward the laser assembly 14 through the support rod 245. When the air is ejected, the dust collection head 110 is close to the place where the anti-counterfeiting label needs to be printed, so that the dust blown away on the surface of the steel is directly absorbed by the dust collection head 110 without causing the dust to be scattered.

[0048] When the cleaning of the steel material where the anti-counterfeiting label needs to be printed is completed, as the cylinder 211 continues to drive the support block 212 to rise, the support block 212 continues to rise through the first cross plate 213 and the second cross plate 217 and the first driving block 216 and the second driving block 2110 connected to the first cross plate 213 and the second cross plate 217, the first driving block 216 and the second driving block 2110 continue to drive the second slider 214 and the third slider 218 to approach each other, and the second slider 214 drives the limiting plate 221 to continue to move, so that the through port 222 is misaligned with the third conduit 23, thereby making the nozzle 17 no longer inhale external air, and the third slider 218 continues to drive the fifth slider 246 to move through the second plane 248 of the third driving block 2111.

[0049] When the first inclined surface 2411 on the fifth slider 246 contacts the second inclined surface 2413 on the limit frame 2412, as the third driving block 2111 continues to drive, the fifth slider 246 moves, causing the fifth slider 246 to move toward the inside of the groove 249, and the fifth slider 246 squeezes the second spring 2410, causing the second spring 2410 to contract. When the fifth slider 246 and the first plane 247 and the second plane 248 of the third driving block 2111 are misaligned, at this time, under the elastic force of the first spring 243, the extended section of the telescopic rod 242 returns to the inside of the barrel of the telescopic rod 242, the extended section of the telescopic rod 242 drives the fourth slider 244 to reset, and the fourth slider 244 drives the fifth slider 246 to reset. When the fifth slider 246 is misaligned with the second inclined surface 2413 of the limit frame 2412, at this time, under the elastic force of the second spring 2 Under the action of the elastic force of 410, the fifth slider 246 automatically resets, so that the third driving block 2111 will no longer drive the fifth slider 246 to move. At the same time, when the fourth slider 244 resets, it will also drive the dust head to reset through the support rod 245, so that the dust suction head 110 is at a certain distance from the laser assembly 14, so that when the dust suction head 110 absorbs dust generated in the process of printing anti-counterfeiting labels, it will not affect the laser emitted by the laser assembly 14, and will not be affected by the high temperature of the laser assembly 14, thereby causing damage to the dust suction head 110. At the same time, the second driving block 2110 is located at the connection between the second inclined groove 219 and the vertical groove 2112, so that when the second driving block 2110 continues to rise, the second driving block 2110 moves inside the vertical groove 2112 and no longer drives the third slider 218 to move, thereby reducing wear;

[0050] At this time, when the fourth slider 244 is reset, as the limit plate 221 continues to move, the opening 222 gradually corresponds to the incision position of the first conduit 111, so that the nozzle 17 can draw protective gas from the inside of the gas box 15 through the first conduit 111 and the opening 222, so that the nozzle 17 can spray the protective gas and cooperate with the laser assembly 14 to print the anti-counterfeiting label on the steel.

[0051] After the printing of the anti-counterfeiting label is completed, as the cylinder 211 drives the supporting block 212 to descend, the supporting block 212 drives the second slider 214 and the third slider 218 to reset through the first transverse plate 213 and the second transverse plate 217 and the first driving block 216 and the second driving block 2110 connected to the first transverse plate 213 and the second transverse plate 217. The second slider 214 and the third slider 218 respectively drive the limiting plate 221 and the third driving block 2111 to reset, so that the limiting plate 221 returns to its initial state. At the same time, when the third driving block 2111 is reset, when the third inclined surface 2414 on the third driving block 2111 contacts the first inclined surface 2411 on the fifth slider 246, the third inclined surface 2414 on the third driving block 2111 squeezes the first inclined surface 2411 on the fifth slider, and will first pass through the fifth slider 24 6 drives the fourth slider 244 to move in the direction away from the cylinder 211, and the fourth slider 244 squeezes the first spring 243, causing the first spring 243 to contract to a certain extent. When the elastic force of the first spring 243 is greater than the elastic force of the second spring 2410, at this time, the third driving block 2111 will squeeze the first inclined surface 2411 on the fifth slider 246 when continuing to reset, causing the fifth slider 246 to move into the inside of the groove 249. The fifth slider 246 squeezes the second spring 2410, causing the second spring 2410 to contract. When the third inclined surface 2414 on the third driving block 2111 is misaligned with the first inclined surface 2411 on the fifth slider 246, the fifth slider 246 is reset under the action of the elastic force of the second spring 2410, and at the same time, the fourth slider 244 is reset under the action of the elastic force of the first spring 243.

[0052] In summary, unlike the above embodiment, this embodiment provides a structure for cleaning the printing area, so that when laser printing anti-counterfeiting labels, the area where the anti-counterfeiting label needs to be printed can be dusted first, ensuring the cleanliness of the area where the anti-counterfeiting label needs to be printed and avoiding dust affecting the printing accuracy. At the same time, when the printed anti-counterfeiting label needs to be cleaned, the dust suction head 110 automatically resets, so that the laser component 14 will not affect the dust suction head 110 during operation, and the dust suction head 110 will not affect the laser emitted by the laser component 14.
