Description

Technical Field

[0001] This utility model relates to the technical field of laser engraving machines, and in particular to a double-sided laser engraving machine. Background Technology

[0002] The atomizing cartridge is one of the core components of an electronic atomizer. It's used to atomize liquids. Currently, most electronic atomizers laser-engrave the surface of the cartridge, such as engraving brand logos, text, or patterns. The two opposite sides of the cartridge are usually designed for laser engraving. The current laser engraving process is as follows:

[0003] First, multiple atomizing cartridges are manually placed into a special fixture in a flat position, with one side of each cartridge facing upwards. Then, this fixture is placed into a laser engraving machine, which then laser engraves one side of each cartridge from top to bottom. After the laser engraving is complete, the fixture is manually rotated 180° so that the other side of each cartridge faces upwards. Then, the laser engraving machine laser engraves the other side of each cartridge from top to bottom.

[0004] However, in order to meet the production requirements of reliably completing automated feeding and unloading of atomizing cartridges, atomizing cartridges are placed vertically into ordinary fixtures in other automated production lines. Therefore, the special fixtures used in laser engraving are different from those used in other automated production processes. This results in operators needing to perform secondary placement of multiple atomizing cartridges (i.e., placing them into ordinary fixtures or special fixtures for laser engraving) throughout the entire production process, leading to lower production efficiency of electronic atomizers. Utility Model Content

[0005] This utility model provides a double-sided laser engraving machine, which mainly solves the technical problem of how to complete the double-sided laser engraving of multiple atomizing bullets without the need for secondary tray placement of multiple atomizing bullets.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A double-sided laser engraving machine includes a frame, a loading and unloading mechanism connected to the frame, and two laser engraving modules respectively disposed on opposite sides of the loading and unloading mechanism. The loading and unloading mechanism is for loading and unloading the two laser engraving modules.

[0008] Both laser engraving modules include a linear module, a rotating mechanism, and a laser engraving machine, each connected to the frame. The linear module drives a fixture to move within the range of motion of the loading and unloading mechanism. The fixture is used to load multiple products. The loading and unloading mechanism places multiple products from the fixture onto the rotating mechanism. The loading and unloading mechanism also returns multiple products from the rotating mechanism back into the fixture. The laser engraving machine is positioned on one side of the rotating mechanism and is used to engrave the sides of multiple products from the rotating mechanism laterally. The rotating mechanism drives multiple products to rotate about a vertical axis, so that the other side of the multiple products can face the laser engraving machine.

[0009] In one of the technical solutions, the loading and unloading mechanism is a robot with multiple degrees of rotational freedom arranged between the two laser engraving modules.

[0010] In one of the technical solutions, the robot includes a base, a first rotating arm, a second rotating arm, a lifting arm, and a material handling module;

[0011] The base is fixed to the frame. The first rotating arm is rotatably connected to the base with a vertical axis as the pivot. The second rotating arm is rotatably connected to the end of the first rotating arm away from the base with a vertical axis as the pivot. The lifting arm and the second rotating arm move up and down longitudinally. The picking module is connected to the lifting arm. The picking module is used to pick up multiple products from the fixture or the rotating mechanism.

[0012] In one of the technical solutions, the material picking module includes a fixed base and two rows of material picking mechanisms connected to the fixed base. The fixed base is fixedly connected to the lifting arm. One row of material picking mechanisms is used to pick up multiple products from the fixture, and the other row of material picking mechanisms is used to pick up multiple products from the rotating mechanism.

[0013] In one of the technical solutions, the rotating mechanism includes a base, a drive assembly, and multiple rotating seats;

[0014] The base is fixedly connected to the frame, and the plurality of rotating seats are rotatably connected to the base with a vertical axis as the pivot. Each of the rotating seats has a placement slot at the top for accommodating a product. The drive assembly is connected to the base and the plurality of rotating seats and is used to drive the plurality of rotating seats to rotate relative to the base.

[0015] In one of the technical solutions, the driving component includes multiple motors fixed on the base, and the multiple motors are connected to multiple rotating seats in a one-to-one correspondence. Each motor is used to drive a corresponding rotating seat to rotate.

[0016] In one of the technical solutions, the rotating mechanism further includes a pressing mechanism, which is connected to the base and located on one side of the plurality of rotating bases. The pressing mechanism is used to apply downward pressure to the products located on the plurality of rotating bases.

[0017] In one of the technical solutions, the pressing mechanism includes a first cylinder, a second cylinder, and a pressure plate connected in sequence;

[0018] The first cylinder is fixed to the base and is used to drive the second cylinder and the pressure plate to move laterally together. The second cylinder is used to drive the pressure plate to move up and down. The descent of the pressure plate is used to apply downward pressure to the top of the products located on the plurality of rotating seats.

[0019] In one of the technical solutions, the laser engraving machine includes a lifting adjustment device and a laser engraving head. The laser engraving head is used to engrave products. The lifting adjustment device is connected to the frame and the laser engraving head respectively and is used to adjust the height of the laser engraving head.

[0020] In one of the technical solutions, the direction in which the linear module drives the fixture toward the loading and unloading mechanism is defined as a first direction. The rotating mechanism is arranged on one side of the linear module along the first direction, and the laser engraving machine is arranged on the side of the rotating mechanism opposite to the loading and unloading mechanism.

[0021] Compared with the prior art, the double-sided laser engraving machine provided by this utility model has at least the following beneficial effects:

[0022] The workflow of the double-sided laser engraving machine in this solution is as follows: First, multiple products (such as atomized bullets) are placed into the fixture. Then, the linear module drives the fixture to move within the range of the loading and unloading mechanism. Next, the loading and unloading mechanism places the multiple atomized bullets from the fixture into the rotating mechanism. Immediately afterwards, the laser engraving machine emits a laser along the horizontal direction to engrave one side of the multiple atomized bullets on the rotating mechanism. After the engraving of a single side is completed, the rotating mechanism drives the multiple atomized bullets to rotate 180° around the vertical axis, so that the other side of the multiple atomized bullets faces the rotating mechanism. The laser engraving machine uses a laser to engrave multiple atomizing bullets on one side in a horizontal direction. After both sides of the multiple atomizing bullets on the rotating mechanism are engraved, the loading and unloading mechanism transfers the multiple atomizing bullets back into the fixture. The above operation process is continuously repeated until all the atomizing bullets in the fixture have been engraved on both sides. Then, the linear module drives the fixture to move away from the fixture so that the operator can take out the multiple double-sided engraved atomizing bullets and replenish the atomizing bullets to be engraved. At this time, the function of double-sided engraving of multiple atomizing bullets is efficiently completed.

[0023] As described above, the laser engraving machine used in this solution emits laser light horizontally to engrave the sides of the atomizing cartridges. Therefore, multiple atomizing cartridges can be placed vertically into the fixture during laser engraving. This solution allows the fixture used for the atomizing cartridges to be identical to those used in other automated production processes, eliminating the need for secondary tray placement before or after laser engraving. In other words, after multiple atomizing cartridges are completed in the previous automated production process, the fixture can be immediately placed into the double-sided laser engraving machine without secondary tray placement. Alternatively, after multiple atomizing cartridges are laser engraved, the operator can quickly transfer the fixture containing the double-sided laser-engraved cartridges to the next automated production process, significantly improving the production efficiency of atomizing cartridges. Furthermore, this solution utilizes two laser engraving modules and designs the loading and unloading mechanisms separately for each module, further enhancing the production efficiency of atomizing cartridges.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] Please refer to the following: Figures 1 to 5This utility model embodiment provides a double-sided laser engraving machine, which mainly includes a frame 1, a loading and unloading mechanism 2 and two laser engraving modules 3. The loading and unloading mechanism 2 is fixed on the frame 1, and the two laser engraving modules 3 are also fixed on the frame 1 and respectively arranged on opposite sides of the loading and unloading mechanism 2, so that the loading and unloading mechanism 2 can load or unload the two laser engraving modules 3 respectively. Each of the two laser engraving modules 3 specifically includes a linear module 31, a rotating mechanism 32, and a laser engraving machine 33, which are fixedly connected to the frame 1. The fixture 4 is used to load multiple products. The linear module 31 is used to drive the fixture 4 to make linear reciprocating motion. Specifically, the linear module 31 is used to drive the fixture 4 to move within the range of the loading and unloading mechanism 2, so that the loading and unloading mechanism 2 can pick up the products to be engraved from the fixture 4. The loading and unloading mechanism 2 is used to place multiple products on the fixture 4 onto the rotating mechanism 32. The loading and unloading mechanism 2 is also used to put multiple engraved products on the rotating mechanism 32 back into the fixture 4. The laser engraving machine 33 is arranged on one side of the rotating mechanism 32. The laser engraving machine 33 is used to engrave the sides of multiple products on the rotating mechanism 32 in the horizontal direction. The rotating mechanism 32 is used to drive multiple products to rotate around a vertical axis, so that the other side of the multiple products can face the laser engraving machine 33. Furthermore, let the direction in which the linear module 31 drives the fixture 4 toward the loading and unloading mechanism 2 be the first direction X. The rotating mechanism 32 is preferably arranged on one side of the linear module 31 along the first direction X, and the laser engraving machine 33 is arranged on the side of the rotating mechanism 32 away from the loading and unloading mechanism 2. By arranging the components in the above-mentioned positions, the overall structure of the double-sided laser engraving machine is made more compact and reasonable.

[0038] The workflow of the double-sided laser engraving machine in this solution is as follows:

[0039] Taking atomized bullets as an example, products requiring laser engraving are first placed into fixture 4. Then, the linear module 31 drives fixture 4 to move within the range of the loading / unloading mechanism 2. Next, the loading / unloading mechanism 2 places the multiple atomized bullets from fixture 4 into the rotating mechanism 32. Immediately afterwards, the laser engraving machine 33 emits a laser along the horizontal direction to engrave one side of the multiple atomized bullets on the rotating mechanism 32. After the engraving of one side of the atomized bullet is completed, the rotating mechanism 32 drives the multiple atomized bullets to rotate 180° around the vertical axis, so that the other side of the multiple atomized bullets faces the laser engraving machine 33. 3. The laser engraving machine 33 performs engraving on the other side of multiple atomizing bullets by emitting laser light horizontally. After both sides of multiple atomizing bullets on the rotating mechanism 32 are engraved, the loading and unloading mechanism 2 transfers multiple atomizing bullets on the rotating mechanism 32 back into the fixture 4. The above operation process is continuously repeated until all atomizing bullets in the fixture 4 have completed double-sided engraving. Then, the linear module 31 drives the fixture 4 to move away from the outside so that the operator can take out multiple double-sided engraved atomizing bullets and replenish the atomizing bullets to be engraved. At this time, the function of double-sided engraving of multiple atomizing bullets is efficiently completed.

[0040] As can be seen from the above, the laser engraving machine 33 used in this solution emits laser light horizontally to engrave the sides of the atomizing bullets. Therefore, multiple atomizing bullets can be placed vertically into the fixture 4 during the laser engraving process. This solution allows the fixture 4 used for the atomizing bullets to be identical to the fixtures used in other automated production processes, eliminating the need for secondary tray placement before or after laser engraving. In other words, after multiple atomizing bullets are completed in the previous automated production process, the fixture 4 can be immediately placed into the double-sided laser engraving machine without secondary tray placement. Alternatively, after multiple atomizing bullets are laser engraved, the operator can quickly transfer the fixture 4 containing multiple double-sided laser-engraved atomizing bullets to the next automated production process, thereby significantly improving the production efficiency of atomizing bullets. Furthermore, this solution, by setting up two laser engraving modules 3 and designing the loading and unloading mechanism 2 to load and unload the two laser engraving modules 3 respectively, further enhances the production efficiency of atomizing bullets.

[0041] Please refer to the following: Figure 1 and Figure 4To enable the loading and unloading mechanism 2 to efficiently load and unload materials from the two laser engraving modules 3, this embodiment preferably designs the loading and unloading mechanism 2 as a robot with multiple rotational degrees of freedom, and this robot needs to be arranged between the two laser engraving modules 3. This robot can be understood to specifically include a base 21, a first rotating arm 22, a second rotating arm 23, a lifting arm 24, and a material-picking module 25. The base 21 is fixed to the frame 1. The first rotating arm 22 is rotatably connected to the base 21 about a vertical axis. The second rotating arm 23 is rotatably connected to the end of the first rotating arm 22 away from the base 21 about a vertical axis. The lifting arm 24 and the second rotating arm 23 can move vertically up and down. The material-picking module 25 is connected to the lifting arm 24. Driven by the lifting arm 24, the material-picking module 25 moves downwards to pick up multiple atomized bullets from the fixture 4 or the rotating mechanism 32. This design ensures that the robot has at least two rotational degrees of freedom and one vertical lifting degree of freedom, enabling the material handling module 25 to achieve efficient material handling.

[0042] Please refer to them again. Figure 1 and Figure 4 The material handling module 25 specifically includes a fixed base 251 and two rows of material handling mechanisms 252 connected to the fixed base 251. The fixed base 251 is fixedly connected to the lifting arm 24. One row of material handling mechanisms 252 is used to pick up multiple atomizing bullets from the fixture 4, and the other row of material handling mechanisms 252 is used to pick up multiple atomizing bullets from the rotating mechanism 32. By setting two material handling mechanisms 252, when multiple atomizing bullets on the rotating mechanism 32 have been laser-engraved, after one material handling mechanism 252 removes the engraved atomizing bullets from the rotating mechanism 32, the other material handling mechanism 252 can immediately replenish multiple atomizing bullets to be engraved into the rotating mechanism 32. This facilitates the efficient supply of products to be engraved to the rotating mechanism 32, thereby further improving the laser engraving efficiency of the atomizing bullets. The material handling mechanism 252 can pick up products by clamping or by negative pressure adsorption.

[0043] Please refer to the following: Figure 1 and Figure 3The rotating mechanism 32 specifically includes a base 321, a drive assembly 322, and multiple rotating seats 323. The base 321 is fixedly connected to the frame 1, and the multiple rotating seats 323 are rotatably connected to the base 321 about a vertical axis. Each rotating seat 323 has a placement slot 3231 on its top for accommodating one product. The drive assembly 322 is connected to the base 321 and the multiple rotating seats 323, and is used to drive the multiple rotating seats 323 to rotate relative to the base 321. During operation, the loading and unloading mechanism 2 places the multiple atomizing bullets from the fixture 4 onto the multiple rotating seats 323 one by one. After one side of the atomizing bullet is engraved, the drive assembly 322 drives the multiple rotating seats 323 to rotate, so that the other side of the multiple atomizing bullets to be engraved faces the laser engraving machine 33, thereby achieving the purpose of rotating the multiple atomizing bullets. Furthermore, since each rotating base 323 rotates independently around its own vertical axis, this design helps ensure that the distance between the multiple atomizing bullets and the laser engraving machine 33 remains constant after rotating 180°. This improves the reliability of the laser engraving machine 33 in engraving multiple atomizing bullets on both sides. Preferably, the drive assembly 322 includes multiple motors 3221, each fixed to the base 321. Each motor 3221 is connected to one of the rotating bases 323, and each motor 3221 drives the rotation of its corresponding rotating base 323. This drive assembly 322 has the advantage of occupying minimal lateral space.

[0044] In other embodiments, the drive assembly 322 may also be designed to include a motor, a rack and multiple gears. The rack is designed to mesh with multiple gears, and the multiple gears are designed to be fixedly connected to multiple rotating seats 323 one by one. Then, the motor drives the rack to move linearly back and forth. This can also realize the function of multiple rotating seats 323 rotating around their own vertical axis.

[0045] Please refer to the following: Figure 1 and Figure 3The rotating mechanism 32 also includes a pressing mechanism 324, which is connected to the base 321 and located on one side of the multiple rotating bases 323. The pressing mechanism 324 is used to apply downward pressure to the atomizing bullets located on the multiple rotating bases 323 to ensure that the multiple atomizing bullets do not move during the laser engraving process and improve the positional accuracy of the laser engraving on the surface of the atomizing bullets. The pressing mechanism 324 specifically includes a first cylinder 3241, a second cylinder 3242, and a pressure plate 3243 connected in sequence. The first cylinder 3241 is fixed on the base 321. During operation, when multiple atomizing bullets are placed on multiple rotating seats 323, the first cylinder 3241 drives the second cylinder 3242 and the pressure plate 3243 to move laterally together, causing the pressure plate 3243 to move above the multiple atomizing bullets. Then, the second cylinder 3242 drives the pressure plate 3243 to move downward. The pressure plate 3243 applies downward pressure to the top of the atomizing bullets located on the multiple rotating seats 323 to compress the multiple atomizing bullets. After the atomizing bullet is engraved on one side, the second cylinder 3242 drives the pressure plate 3243 to rise. Then, the multiple atomizing bullets rotate 180°. The second cylinder 3242 drives the pressure plate 3243 to move downward again to press the multiple atomizing bullets again. When the multiple atomizing bullets are engraved on both sides, the second cylinder 3242 drives the pressure plate 3243 to rise. The first cylinder 3241 drives the second cylinder 3242 and the pressure plate 3243 to move laterally away from the multiple atomizing bullets, so that the pressure plate 3243 is no longer above the multiple atomizing bullets, so that the loading and unloading mechanism 2 can take out the atomizing bullets that have been engraved on both sides from the rotating seat 323 from top to bottom.

[0046] Please refer to the following: Figure 1 and Figure 5 The laser engraving machine 33 specifically includes a lifting adjustment device 331 and a laser engraving head 332. The laser engraving head 332 is used to engrave the surface of the atomized bullet. The lifting adjustment device 331 is connected to the frame 1 and the laser engraving head 332 respectively and is used to adjust the height of the laser engraving head 332 so that the laser engraving head 332 can accurately engrave on the designated position of the atomized bullet. In addition, it is also conducive to the laser engraving needs of atomized bullets of different heights.

[0047] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
