Description

Technical Field

[0001] The present application relates to the field of laser marking technology, and in particular to a fully automatic laser marking production line and method for label production. Background Art

[0002] At present, laser marking is a marking method that uses high-energy-density lasers to partially irradiate workpieces, causing the surface material to vaporize or undergo a chemical reaction that changes color, thereby leaving a permanent mark. Laser marking can produce a variety of text, symbols, and patterns, and the character size can range from millimeters to micrometers, which is of special significance for product anti-counterfeiting.

[0003] The existing Chinese patent with publication number CN217965312U discloses a new type of automatic laser marking machine, including a cabinet, a lifting and moving adjustment device is installed at the left rear of the top of the cabinet, a display screen is installed on the right side of the lifting and moving adjustment device, a driving component is installed on the front side of the top of the cabinet, a conveyor belt is installed on the surface of the driving component, a clamping component and a limit component are respectively installed on the surface of the conveyor belt, a laser marker is installed on the front of the lifting and moving adjustment device, and a control panel is installed on the right rear of the top of the cabinet.

[0004] When using the above-mentioned laser marking machine to mark the label, the staff manually installs the label on the conveyor belt through the clamping component, and then the driving component drives the conveyor belt to rotate. When the label moves with the conveyor belt to the lower side of the laser marker and passes by, the laser marker marks the label, and this cycle is repeated to complete the label marking.

[0005] The staff manually clamps the label on the clamping assembly. During the clamping process, the staff rotates turntable one and turntable two so that the clamping plate and the limit plate clamp the label. During the clamping process, the position of the label is adjusted so that the label can remain centered and the pattern marked by the laser marking machine can be formed in the center of the label. When it is necessary to mark the other side of the label, adjust the clamping assembly to loosen the label, and then flip the label. After the label is flipped, use the clamping assembly again to clamp the label. After the label marking is completed, the staff removes the label from the clamping assembly for packing.

[0006] With respect to the above-mentioned related technologies, the manual clamping, adjustment and packing of labels has a low degree of automation, which reduces the production efficiency of the labels. Summary of the invention

[0012] Through the above technical solution, the label, box body and cover body are prevented from being stored in the storage cavity of the storage box, and then the pushing cylinder drives the pushing block to reciprocate in the pushing channel on the lower side of the storage box. As the pushing block moves, the pushing block pushes the label, box body and cover body out of the corresponding storage box, thereby improving the convenience of pushing the label and box body out of the storage box.

[0013] Furthermore, an adjusting bolt is provided on the push block, one end of the adjusting bolt passes through the piston rod of the push cylinder, and the adjusting bolt passes through one end of the piston rod of the push cylinder to be rotatably connected to the push block.

[0019] Furthermore, the positioning assembly includes a positioning plate, the positioning plate corresponds to the storage box, a limiting groove is provided on the positioning plate, and the limiting groove is connected to the pushing channel.

[0020] Through the above technical solution, after the label, box body and box cover are pushed out of the storage box, the limiting grooves on the positioning plate position the label, box body and box cover, so that the grabbing assembly can accurately grab the label, box body and box cover.

[0021] Furthermore, a positioning block is slidably mounted on the second conveying frame, a positioning slot is formed on the positioning block, a guiding inclined surface is formed on the positioning block, and the guiding inclined surface is inclined toward one side of the positioning slot.

[0022] Through the above technical solution, when the label is placed on the positioning block, the guide bevel positions the label so that the label can be placed in the positioning groove of the positioning block. In addition, the positioning groove can also prevent the label from shifting during the marking process.

[0024] Through the above technical solution, after marking on one side of the label is completed, the two chucks clamp the label in the clamping groove, and then the flip cylinder drives the slider to slide. During the sliding process of the slider, the gear on the flip block engages with the rack on the positioning block. As the slider slides, the flip block drives the label to flip. After the label is flipped, the laser marking machine marks the other side of the label.

[0025] Furthermore, a diaphragm is provided in the flip block, and a first air cavity and a second air cavity are formed on both sides of the diaphragm respectively; a first air pipe and a second air pipe are provided on the flip block, the first air pipe is connected to the first air cavity, and the second air pipe is connected to the second air cavity; a clamp membrane is provided on the chuck, and a clamp cavity is formed between the clamp membrane and the chuck, and a catheter is provided on the chuck, one end of the catheter is connected to the chuck, and the other end is inserted into the flip block, and the catheter is connected to the second air cavity and the clamp cavity.

[0026] Through the above technical solution, the air supply device inflates the first air cavity through the first air pipe. During the inflation process in the first air cavity, the diaphragm slides the clamp to the side away from the flip block through the catheter, and then supplies air to the second air cavity through the second air pipe. The gas in the second air cavity is ventilated to the clamp cavity through the catheter. As the clamp cavity is inflated, the clamp membrane on the clamp deforms to the side close to each other, thereby enabling the label to be clamped.

[0053] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0054] The following combination Figure 1-Figure 7 This application is described in further detail.

[0055] The present application discloses a fully automatic laser marking production line and method for label production.

[0056] Reference Figure 1 A fully automatic laser marking production line for label production includes a frame 1, on which a storage box 2 is installed, and the storage box 2 stores labels, box bodies and lids. A laser marking machine 11 is also provided on the frame 1, and the laser marking machine 11 marks the labels. The frame 1 is provided with a pushing component 3, a grabbing component 4, a conveying component 5, a positioning component 6 and a flipping component 7. The pushing component 3 pushes the label, the box body and the lid out of the storage box 2, the grabbing component 4 grabs the label, the box body and the lid, the conveying component 5 conveys the label, the box body and the lid, and the positioning component 6 positions the label during the conveying process. After the laser marking machine 11 completes marking on one side of the label, the flipping component 7 flips the label.

[0057] The frame 1 is rectangular as a whole, and a processing area 12 and a finished product area 13 are formed on both sides of the frame 1 in the length direction. After the label is marked by the laser marking machine 11 from the processing area 12 of the frame 1, the conveying component 5 conveys the label to one side of the finished product area 13.

[0058] Three material storage boxes 2 are arranged at intervals on the frame 1 , and the three material storage boxes 2 are arranged at intervals along the length direction of the frame 1 . The three material storage boxes 2 store labels, box bodies and box covers in sequence.

[0059] Reference Figure 2-Figure 3 The material storage box 2 is a hollow shell structure as a whole, and a material storage cavity 21 is formed in the material storage box 2, and the cross section of the material storage box 2 is rectangular. Further, the top surface and the bottom surface of the material storage box 2 are set through, and when the corresponding label, box body and cover body are put in from the top of the material storage box 2, the label, box body and cover body will pass through the material storage cavity 21 of the material storage box 2 and fall out from the bottom. A support plate 22 is provided on the frame 1, and the support plate 22 is a rectangular plate as a whole, and the support plate 22 is horizontally installed on the frame 1, and the material storage box 2 is installed on the support plate 22. A groove 221 is formed on the support plate 22, and when a number of labels, box bodies and box covers are put into the corresponding material storage box 2, the labels, box bodies and box covers are placed on the groove 221 of the support plate 22.

[0060] A push channel 23 is provided on one side of the material storage box 2 close to the support plate 22, and the push channel 23 is communicated with the material storage cavity 21. When in use, the label, the box body and the box cover are pushed out from the push channel 23 of the corresponding material storage box 2.

[0061] Reference Figure 2-Figure 3In order to improve the convenience of pushing the label, the box body and the box cover out of the material storage box 2, the pushing assembly 3 includes a pushing cylinder 31, which is installed on the side of the support plate 22 away from the material storage box 2, and the axis of the piston rod of the pushing cylinder 31 is coaxial with the axis of the support plate 22. A pushing block 32 is provided on the pushing cylinder 31, and a slide groove 321 is formed on the pushing block 32. The pushing cylinder 31 drives the pushing block 32 through the slide groove 321 to slide and cooperate with the pushing cylinder 31 through the piston rod.

[0062] A pushing surface 322 is formed on one side of the pushing block 32 close to the pushing cylinder 31, and the pushing surface 322 is perpendicular to the upper surface of the support plate 22. When in use, the pushing cylinder 31 drives the pushing block 32 to reciprocate under the storage box 2. During the movement of the pushing block 32, the pushing surface 322 on one side of the pushing block 32 presses against the corresponding label, box body or cover body, so that the label, box body or cover body slides out of the pushing channel 23 under the storage box 2 along with the pushing block 32.

[0063] When in use, the thickness of the label, the box body and the box cover are different. If the distance between the top of the pushing surface 322 on one side of the push block 32 and the surface of the support plate 22 is too large or too small, the corresponding label, box body or cover cannot be pushed out of the storage box 2. Therefore, an adjusting bolt 323 is provided on the push block 32, and the adjusting bolt 323 is threadedly connected with the piston rod of the push cylinder 31, and one end of the adjusting bolt 323 passes through the piston rod of the push cylinder 31 and is rotatably connected to the push block 32. When in use, the staff rotates the adjusting bolt 323 to adjust the distance between the push block 32 and the upper surface of the support plate 22, so that the push block 32 can be used for labels, box bodies and box covers of different thicknesses.

[0064] Reference Figure 1-Figure 2 , the position of the label, the box body and the box cover after being pushed out of the storage box 2 is then offset, affecting the subsequent marking effect. Therefore, the positioning component 6 includes a positioning plate 61, and the positioning plate 61 corresponds to the storage box 2. A limiting groove 611 is provided on the positioning plate 61, and the cross-section of the limiting groove 611 is rectangular, and one side of the limiting groove 611 in the length direction is open, and the open side of the limiting groove 611 is connected to the pushing channel 23. When the label, the box body and the cover are pushed out of the storage box 2, they are embedded in the limiting groove 611 of the positioning plate 61. This prevents the position of the label, the box body and the cover from being offset on the support plate 22 due to inertia.

[0065] Reference Figure 2-Figure 3Furthermore, a sensor 222 is installed on the support plate 22, and the sensor 222 is connected to the push cylinder 31. A sensing port is provided on the support plate 22, and the sensing port is connected to the limit groove 611. When the label, the box body and the cover body are sensed by the sensor 222 in the limit groove 611, the push cylinder 31 will no longer push out the corresponding label, the box body and the cover body. If the sensor 222 does not sense the label, the box body and the cover body, the sensor 222 will send a push signal to the push cylinder 31, and at this time, the corresponding label, the box body and the cover body are pushed out from the storage box 2.

[0066] Reference Figure 4 The conveying assembly 5 includes a first conveying frame 51, on which a first conveying belt 511 and a first driving motor 512 are provided, and the first conveying belt 511 is rotatably mounted on the first conveying frame 51. The first driving motor 512 is mounted on the first conveying frame 51, and when in use, the first driving motor 512 drives the first conveying belt 511 to rotate on the first conveying frame 51.

[0067] Reference Figure 1 The grab assembly 4 includes a first mechanical arm 41, which is located on the side of the first conveyor frame 51 close to the storage box 2 where the label is placed. In addition, a first suction cup 411 and a first air extraction pipe 412 connected to the first suction cup 411 are installed on the first mechanical arm 41. When the label is pushed out of the storage box 2, the first mechanical arm 41 presses the first suction cup 411 against the label, and then the external air extraction device extracts the air between the label and the first suction cup 411 through the first air extraction pipe 412, and then the first mechanical arm 41 transfers the label to the first conveyor belt 511, and the first drive motor 512 drives the first conveyor belt 511 to rotate on the first conveyor frame 51, and as the first drive motor 512 rotates, the label moves following the first conveyor belt 511.

[0068] Reference Figure 4 , the position of the label is prone to shift during the conveying process of the first conveyor belt 511, in order to further improve the accuracy of the position of the label during transportation. A baffle 62 is installed on the first conveyor frame 51, and the baffle 62 is installed across the first conveyor frame 51 on both sides of the first conveyor belt 511. A retaining groove 621 is provided on the baffle 62, and the retaining groove 621 faces the side relative to the first conveyor belt 511. In addition, a guide arc surface 622 is formed on the baffle 62, and the guide arc surface 622 is inclined toward the inner side of the retaining groove 621. As the label is conveyed on the first conveyor belt 511, the guide arc surface 622 on the baffle 62 guides the label so that the label enters the retaining groove 621 of the baffle 62. In addition, due to the obstruction of the baffle 62, the label will not move with the movement of the first conveyor belt 511.

[0069] The laser marking machine 11 is installed on one side of the conveying direction of the first conveyor belt 511, and the conveying assembly 5 includes a second conveyor frame 52, on which a second conveyor belt 521 and a second drive motor 522 are installed. The second conveyor belt 521 is rotatably installed on the second conveyor frame 52, and the second drive motor 522 is installed on the second conveyor frame 52, and the second drive motor 522 drives the second conveyor belt 521 to rotate.

[0070] Reference Figure 5 A positioning block 14 is slidably mounted on the second conveyor frame 52 , and the positioning block 14 is connected to the second conveyor belt 521 . When in use, the second drive motor 522 realizes the reciprocating movement of the positioning block 14 on the second conveyor frame 52 by forward and reverse rotation.

[0071] Reference Figure 1 , Figure 5-Figure 6 A positioning groove 141 is formed on the positioning block 14, and the label is placed in the positioning groove 141 of the positioning block 14. Then the label follows the positioning block 14 to slide on the second conveyor frame 52. When the positioning block 14 drives the label to move to the lower side of the laser marking machine 11, the laser marking machine 11 marks the label.

[0072] In order to facilitate the placement of the label in the positioning groove 141, a guiding slope 142 is formed on the positioning block 14, and the guiding slope 142 is inclined toward the inner side of the positioning groove 141. When the label is placed in the positioning groove 141, the guiding slope 142 guides the label so that the label can be placed in the positioning groove 141 of the positioning block 14.

[0073] Reference Figure 1 , Figure 4-Figure 6 Furthermore, the grabbing assembly 4 also includes a second robotic arm 42, and the second robotic arm 42 is located between the first conveying frame 51 and the second conveying frame 52. A second suction cup 421 and a second exhaust pipe 422 are installed on the second robotic arm 42, and an external exhaust device exhausts air from the second suction cup 421 through the second exhaust pipe 422. When in use, the second robotic arm 42 places the second suction cup 421 against the label in the retaining groove 621, and then the external exhaust device extracts the gas between the second suction cup 421 and the label through the second exhaust pipe 422, and then the second robotic arm 42 moves the label to above the positioning groove 141 of the positioning block 14, and then blows air between the second suction cup 421 and the label through the second exhaust pipe 422, so that the label falls into the positioning groove 141 of the positioning block 14.

[0074] During the process of marking the labels, some labels need to be marked on both sides. During the marking process, the staff needs to flip the labels, which increases the workload of the staff. The positioning block 14 is rectangular as a whole, and one group of flipping components 7 is installed on both sides of the length direction of the positioning block 14, and the two groups of flipping components 7 are arranged opposite to each other. When in use, the flipping components 7 on both sides flip the labels. The structures and functions of the two groups of flipping components 7 are the same, and only one group of flipping components 7 is described below.

[0075] Reference Figure 6-Figure 7 A mounting plate 71 is provided on one side of the length direction of the positioning block 14, and the mounting plate 71 is tightened on the positioning block 14 by bolts. Clamping openings 143 are provided at both ends of the length direction of the positioning block 14, and the clamping openings 143 on both sides are connected to the positioning groove 141.

[0076] Reference Figure 7 The flip assembly 7 includes a slider 72 and a flip block 73. The slider 72 is slidably mounted on the side of the mounting plate 71 close to the positioning block 14. The flip block 73 is located on the side of the slider 72 close to the positioning block 14. A rotating shaft 731 is mounted on the flip block 73. One end of the rotating shaft 731 is connected to the flip block 73, and the other end passes through the slider 72 and the mounting plate 71 in sequence. The flip block 73 is rotatably connected to the slider 72 through the rotating shaft 731. A gear 732 is mounted on one end of the rotating shaft 731 passing through the mounting plate 71. A rack 74 is mounted on the side of the mounting plate 71 away from the positioning block 14. When the slider 72 drives the flip block 73 to slide, the gear 732 rotates through the rack 74. At this time, the flip block 73 rotates 180 degrees on the slider 72, thereby causing the label to flip.

[0077] The mounting plate 71 is provided with a flip cylinder 75, and two flip cylinders 75 are vertically mounted on the mounting plate 71. The piston rods of the two flip cylinders 75 are connected to the slider 72, and the flip cylinders 75 drive the slider 72 to slide on the mounting plate 71. In addition, a guide groove 711 is provided on the mounting plate 71, and the rotating shaft 731 passes through the guide groove 711 of the mounting plate 71. When the slider 72 slides, the guide groove 711 guides the rotating shaft 731.

[0078] A clamp 76 is provided on the flip block 73 . Two clamps 76 are installed on the flip block 73 at intervals. A clamping groove is formed between the two clamps 76 . The label is clamped in the clamping groove of the clamp 76 .

[0079] In order to improve the convenience of clamping the label by the clamping head 76, a clamping film 761 is installed on each of the two clamping heads 76, and a clamping cavity 762 is formed between the clamping film 761 and the corresponding clamping head 76. Furthermore, a conduit 763 is provided between the clamping head 76 and the flip block 73, one end of the conduit 763 is connected to the clamping head 76, and the other end is inserted into the flip block 73, and the conduit 763 communicates with the interior of the flip block 73 and the clamping cavity 762.

[0080] Furthermore, a diaphragm 733 is provided in the flip block 73 , and a first air cavity 734 and a second air cavity 735 are formed on both sides of the diaphragm 733 , respectively. One end of the conduit 763 extending into the flip block 73 is connected to the second air cavity 735 .

[0081] The flip block 73 is provided with a first air pipe 7341 and a second air pipe 7351 . The first air pipe 7341 is connected to the first air cavity 734 , and the second air pipe 7351 is connected to the second air cavity 735 . When in use, the external hose is connected to the first air pipe 7341 and the second air pipe 7351 respectively.

[0082] When in use, the first air cavity 734 is inflated through the first air pipe 7341. At this time, the diaphragm 733 is deformed toward the side of the second air cavity 735. During the deformation process, the diaphragm 733 pushes the conduit 763 toward the side close to the positioning block 14, so that the clamp 76 enters the clamping opening 143. Since the label is placed between the clamps 761, the second air cavity 735 is inflated through the second air pipe 7351. At this time, the gas enters the clamping cavity 762 of the clamp 76 through the conduit 763. As the clamping cavity 762 is filled with gas, the clamps 761 on the two clamps 76 are deformed toward the side close to each other, so that the clamps 76 can clamp the label.

[0083] One end of the conduit 763 that penetrates the second air cavity 735 is provided with a support spring 764, which is sleeved on the conduit 763, with one end of the support spring 764 pressed against the conduit 763, and the other end pressed against the inner side of the flip block 73. When the chuck 76 moves toward the side close to the positioning block 14 under the action of the diaphragm 733, the support spring 764 is in a compressed state, and after the first air cavity 734 is depressurized, the chuck 76 moves toward the side away from the positioning block 14 under the action of the support spring 764.

[0084] Reference Figure 1 After the label is turned over on the positioning block 14, the laser marking machine 11 marks the other side of the label. After the label is marked, the label needs to be boxed. Therefore, the grabbing assembly 4 also includes a third mechanical arm 43, and the third mechanical arm 43 is located on the side of the second conveying frame 52 away from the first conveying frame 51. The third mechanical arm 43 is equipped with a third suction cup 431 and a third exhaust pipe 432. After the label is marked, the positioning block 14 drives the label to slide to the side close to the third mechanical arm 43.

[0085] An assembly table 15 is provided on one side of the frame 1 close to the third robotic arm 43, and an assembly groove 151 is formed on the assembly table 15. When the label slides toward the third robotic arm 43, the box body and the cover body are respectively pushed out from the corresponding storage box 2. The third robotic arm 43 first places the box body in the device groove of the assembly table 15, and then puts the label into the box body, and then grabs the cover body and puts the cover body on the box body.

[0086] Reference Figure 1 After the label is assembled, the conveying assembly 5 further includes a third conveying frame 53, on which a third conveying belt 531 and a third driving motor 532 are installed, and the third driving motor 532 drives the third conveying belt 531 to rotate on the third conveying frame 53. A transfer block 533 is slidably installed on the third conveying frame 53, and the transfer block 533 is connected to the third conveying belt 531. When in use, the third driving motor 532 drives the transfer block 533 to slide on the third conveying frame 53 by forward and reverse rotation.

[0087] Reference Figure 1 The grab assembly 4 includes a fourth robot arm 44, which is mounted on the transfer block 533. A storage rack 16 is placed on one side of the frame 1 close to the third conveyor rack 53, and a storage slot 161 is formed on the storage rack 16. A plurality of storage slots 161 are formed at intervals on the storage rack 16. After the labels are boxed on the assembly table 15, the fourth robot arm 44 places the labels on the assembly table 15 on the storage rack 16, thereby completing the labeling and storage of the labels.

[0088] A fully automatic laser marking method for label production comprises the following steps:

[0089] The pushing cylinder 31 pushes the label, the box body and the cover body out of the storage box 2; the pushing cylinder 31 is installed on the side of the support plate 22 away from the storage box 2, and a pushing block 32 is provided on the pushing cylinder 31, and a slide groove 321 is formed on the pushing block 32. The pushing cylinder 31 drives the pushing block 32 to slide and cooperate with the pushing cylinder 31 through the slide groove 321 through the piston rod.

[0090] A pushing surface 322 is formed on one side of the pushing block 32 close to the pushing cylinder 31, and the pushing surface 322 is perpendicular to the upper surface of the support plate 22. When in use, the pushing cylinder 31 drives the pushing block 32 to reciprocate under the storage box 2. During the movement of the pushing block 32, the pushing surface 322 on one side of the pushing block 32 presses against the corresponding label, box body or cover body, so that the label, box body or cover body slides out of the pushing channel 23 under the storage box 2 along with the pushing block 32.

[0091] The first mechanical arm 41 grabs the label and places it on the first conveyor belt 511. At this time, the label enters a state to be marked.

[0092] The second robot arm 42 places the label on the first conveyor belt 511 in the positioning groove 141 of the positioning block 14, and the positioning block 14 slides to the lower side of the laser marking machine 11, and the laser marking machine 11 completes marking on one side of the label;

[0093] Gas is introduced into the first gas cavity 734. At this time, the diaphragm 733 moves the clamp 76 to the side close to the positioning block 14. When the label enters the clamping groove between the two clamping blocks, gas is introduced into the second gas cavity 735. The gas enters the gas cavity of the clamp 76 through the conduit 763. With the introduction of gas, the clamp 761 clamps the label;

[0094] The flip cylinder 75 drives the slider 72 to slide upward. As the slider 72 slides, the gear 732 meshes with the rack 74, and the flip block 73 flips on the slider 72. After the flip block 73 flips 180 degrees, the flip cylinder 75 re-places the label in the positioning groove 141 of the positioning block 14.

[0095] The third robot arm 43 places the box body on the assembly table 15, then places the label in the box body, and then covers the box body;

[0096] The fourth robot arm 44 places the label box on the assembly table 15 on the storage rack 16, thereby completing the production of the label.

[0097] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
