Description

Technical Field

[0001] This invention relates to the field of manufacturing technology for freshly brewed tea beverage machines, and in particular to a laser marking machine for manufacturing freshly brewed tea beverage machines. Background Technology

[0002] A freshly brewed tea machine, also known as a smart tea machine, automatic tea maker, or tea and coffee machine, is a commercial device that integrates automation, IoT, and precision fluid control technologies. Its core objective is to produce a standardized and efficient base tea infusion. It is a key piece of equipment in the kitchens of modern tea shops (such as Heytea and Nayuki) and fast-food restaurants (such as McDonald's and KFC). During the manufacturing process, permanent serial numbers, production dates, and batch numbers need to be marked on the machine body and key components. The brand logo, equipment model, and rated parameters also need to be engraved. Marking is also required on some internal metal or plastic parts, necessitating the use of a laser marking machine. Simply place the freshly brewed tea machine on the laser marking machine to perform the marking operation. However, in the actual processing, due to the special nature of the instant tea beverage machine—that is, some parts of the instant tea beverage machine are relatively thin—the laser marking operation generates splatter that can cause dents in other parts of the instant tea beverage machine. Sometimes, a protective sleeve is fitted onto the outside of the laser marking machine's processing head. However, since the position of the protective sleeve is fixed, and because the marking pattern is irregular and complex, and the marking area is relatively large, in order to prevent the protective sleeve from directly contacting the instant tea beverage machine, a certain gap is created between the protective sleeve and the instant tea beverage machine, ultimately resulting in limited protection. Therefore, a laser marking machine for manufacturing instant tea beverage machines is provided. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a laser marking machine for manufacturing freshly brewed tea beverage machines.

[0004] The present invention adopts the following technical solution: A laser marking machine for manufacturing freshly brewed tea beverage machines includes a support frame and a transport assembly. A working arm is fixedly mounted on the support frame via a lifting assembly. A working head is fixedly connected to the side wall of the working arm. A sleeve is slidably fitted onto the working head. A control assembly for controlling the position of the sleeve is fixedly mounted on the working head. An automatic adjustment assembly is mounted on the sleeve. The automatic adjustment assembly includes multiple rotating rods slidably mounted on the lower side of the sleeve. A first spring is fixedly connected between the rotating rods and the sleeve. A rotating frame is rotatably connected to the rotating rods. A rotating shaft is rotatably connected inside the rotating frame. A roller is fixedly connected to the rotating shaft. An obstruction assembly is installed between two adjacent rotating frames.

[0005] Preferably, the control component includes a fixed plate fixedly mounted on the working head, the fixed plate being rotatably connected to a rotating threaded rod, the rotating threaded rod being threadedly connected to a rotating threaded plate, the rotating threaded plate being fixedly connected to two first connecting rods, the two first connecting rods being fixedly connected to a slider, the slider being slidably connected to the working head, and the slider being fixedly connected to a sleeve via a second connecting rod.

[0006] Preferably, the obstruction assembly includes a limiting groove on the side wall of the rotating frame, a sliding rod slidably connected to the limiting groove, a cylinder fixedly connected to the sliding rod, a connecting frame rotatably sleeved on the cylinder, a fixed cylinder fixedly connected to the connecting frame, a middle block slidably sleeved on two adjacent fixed cylinders, a third spring fixedly connected between the middle block and the fixed cylinder, control rods fixedly connected to the upper and lower sides of the middle block, control plates fixedly connected to the control rods, a middle rod fixedly connected to the control plates, two first connecting plates rotatably sleeved on the upper and lower sides of the middle rod, a second connecting plate slidably sleeved on the two first connecting plates, and a rotatably connected second connecting plate to the connecting frame.

[0007] Preferably, a cleaning assembly is fixedly installed inside the sleeve. The cleaning assembly includes a sliding plate that is slidably connected to the sleeve. A second spring is fixedly connected between the sliding plate and the sleeve. A third connecting rod is fixedly connected to the lower side of the sliding plate. An arc-shaped plate is fixedly connected to the side wall of the sliding plate.

[0008] Preferably, a plurality of telescopic rods are fixedly connected inside the sleeve, the positions and number of the plurality of telescopic rods are opposite to the arc plate, a triangular block is fixedly connected to the lower side of the arc plate, a trapezoidal block is fixedly connected to the side wall of the telescopic rod, and a calibration head is fixedly connected to the end of the telescopic rod.

[0009] Preferably, the transport assembly includes a motor fixedly mounted on the side wall of the support, and multiple transport rollers are rotatably connected inside the support. One of the transport rollers is fixedly connected to the output end of the motor, and a transport belt is sleeved on the outer side of the multiple transport rollers.

[0010] Preferably, the lifting assembly includes a square cylinder fixedly installed on the side wall of the bracket, a lifting threaded rod rotatably connected inside the square cylinder, a lifting threaded plate threadedly connected to the outside of the lifting threaded rod, a movable frame slidably connected to the outside of the square cylinder, the movable frame being fixedly connected to the working arm, the lifting threaded plate being fixedly connected to the movable frame, and a turntable being fixedly connected to the upper end of the lifting threaded rod.

[0011] The beneficial effects of this invention are: 1. First, during the laser marking process, the position of the sleeve is adjusted by rotating the threaded rod so that the roller at the bottom of the sleeve is always in contact with the tea dispenser. This maximizes the protection of the sleeve and reduces the possibility of splashing everywhere. 2. Secondly, when using the sleeve for protection, it simply blocks the gap between two adjacent rotating frames, forming a simple seal, further reducing the possibility of splashing onto the outside of the sleeve. In this process, when one of the rollers moves to a higher position, the slide rod, cylinder, first connecting plate, and second connecting plate connected to the roller move accordingly. Therefore, the first connecting plate and the second connecting plate will not interfere with the instant tea machine, ultimately achieving an automatic adjustment effect. 3. Then, during the laser marking process, the curved plate will move up and down, thereby cleaning up any splatter that may stick to the inner wall of the sleeve, so that the sleeve always maintains a suitable working condition. 4. Finally, during the testing process, the up-and-down moving arc plate drives the triangular block to move. The triangular block and the trapezoidal block collide, which drives the calibration head to move back and forth, adjusting the position of the calibration head, thereby improving the monitoring effect.

Detailed Implementation

[0014] See Figures 1-13 A laser marking machine for manufacturing freshly brewed tea drinks includes a support frame 1 and a transport component 2. The transport component 2 includes a motor 21 fixedly installed on the side wall of the support frame 1. Multiple transport rollers 22 are rotatably connected inside the support frame 1. One of the transport rollers 22 is fixedly connected to the output end of the motor 21. A transport belt 23 is sleeved on the outer side of the multiple transport rollers 22. First, when it is necessary to perform coding on the freshly made tea beverage machine, place the freshly made tea beverage machine on the conveyor belt 23, start the motor 21, the motor 21 drives the conveyor roller 22 to rotate, which in turn drives the conveyor belt 23 and the freshly made tea beverage machine placed on the upper side of the conveyor belt 23 to move, so that the freshly made tea beverage machine is moved to the appropriate processing position, and the corresponding coding operation can be started. A working arm 3 is fixedly installed on the upper side of the support 1 via a lifting assembly 4. A working head 5 is fixedly connected to the side wall of the working arm 3. A sleeve 6 is slidably sleeved on the outside of the working head 5. The lifting assembly 4 includes a square tube 41 fixedly installed on the side wall of the support 1. A lifting threaded rod 44 is rotatably connected through the square tube 41. A lifting threaded plate 45 is threadedly connected to the outside of the lifting threaded rod 44. A movable frame 43 is slidably connected to the outside of the square tube 41. The movable frame 43 is fixedly connected to the working arm 3. The lifting threaded plate 45 is fixedly connected to the movable frame 43. A turntable 42 is fixedly connected to the upper end of the lifting threaded rod 44. Before performing the coding operation, adjust the overall height of the working arm 3 and the working head 5 according to the actual height of the freshly brewed tea machine and the position to be coded. First, rotate the turntable 42, which drives the lifting threaded rod 44 to rotate. Since the lifting threaded rod 44 and the lifting threaded plate 45 are threadedly connected, and the moving frame 43 and the square cylinder 41 are slidably connected, and the moving frame 43, the lifting threaded plate 45, and the working arm 3 are all fixedly connected, the rotating lifting threaded rod 44 will drive the working arm 3 and the working head 5 to move up and down relative to the square cylinder 41 until the position of the working head 5 meets the working requirements. Then, start the working arm 3 and the working head 5 to begin the coding operation. Secondly, a control system is fixedly installed inside the working arm 3, which is mainly responsible for: receiving instructions, receiving the text, graphics, serial numbers, QR codes and other content to be marked from the upper computer; signal conversion: converting digital information into analog signals to control the deflection of the galvanometer motor and the switching signals to control the laser output; and collaborative work: precisely synchronizing the "switching" of the laser and the "scanning path" of the galvanometer to ensure that the preset pattern is "drawn" on the workpiece. Furthermore, a galvanometer system is fixedly installed inside the working arm 3, mainly consisting of: X-axis and Y-axis galvanometer motors: each motor is equipped with a reflector, and the deflection angle of the motor can be precisely changed by controlling the computer; field lens: also known as a focusing lens, the parallel laser beam reflected by the galvanometer is focused onto a flat focal plane by the field lens, and the quality of the field lens directly determines the fineness and uniformity of the marking effect; When coding is required, the galvanometer system is activated through the control system, so that the laser is emitted from the working head 5, and then the laser coding operation can begin. A control assembly for controlling the position of the sleeve 6 is fixedly installed on the outside of the working head 5. The control assembly includes a fixed plate 7 fixedly installed on the upper side of the working head 5. The fixed plate 7 is rotatably connected to a rotating threaded rod 8. A rotating threaded plate 9 is threadedly connected to the outside of the rotating threaded rod 8. Two first connecting rods 10 are fixedly connected to the lower side of the rotating threaded plate 9. A slider 11 is fixedly connected to the lower side of the two first connecting rods 10. The slider 11 and the working head 5 are slidably connected. The slider 11 is fixedly connected to the sleeve 6 through a second connecting rod 12. Before performing the coding operation, adjust the position of the sleeve 6 according to the actual work needs so that the lower end of the sleeve 6 will never collide with the freshly made tea beverage machine during the coding process. First, rotate the threaded rod 8. Since the slider 11 and the working head 5 are connected by sliding up and down, and the sleeve 6, the first connecting rod 10, the second connecting rod 12 and the rotating threaded plate 9 are fixedly connected, and the rotating threaded plate 9 and the rotating threaded rod 8 are threadedly connected, the rotating threaded rod 8 will drive the rotating threaded plate 9, the first connecting rod 10, the second connecting rod 12 and the sleeve 6 to move up and down relative to the working head 5 until the position of the sleeve 6 meets the work needs, thus completing the adjustment and fixing operation of the position of the sleeve 6. An automatic adjustment assembly is installed on the lower side of the sleeve 6. The automatic adjustment assembly includes multiple rotating rods 14 that are slidably installed on the lower side of the sleeve 6. A first spring 18 is fixedly connected between the rotating rods 14 and the sleeve 6. A rotating frame 13 is rotatably connected to the lower side of the rotating rods 14. A rotating shaft 16 is rotatably connected inside the rotating frame 13. A roller 17 is fixedly connected to the outer side of the rotating shaft 16. An obstruction assembly is installed between two adjacent rotating frames 13. During the coding operation, the roller 17 abuts against the instant tea machine, and the first spring 18 is in a compressed state. During the coding operation, the roller 17 and the rotating frame 13 are similar to the structure of a caster wheel in real life. Therefore, the multiple rotating frames 13 are in a parallel state. The surface of the instant tea machine is uneven. Under the action of the roller 17, the lower end of the sleeve 6 will never abut against the instant tea machine, so that the sleeve 6 always maintains a good working condition, reduces the splash range, and thus maintains the coding quality. The obstruction assembly includes a limiting groove 15 on the side wall of the rotating frame 13. A sliding rod 30 is slidably connected to the limiting groove 15. A cylinder 31 is fixedly connected to the end of the sliding rod 30 away from the limiting groove 15. A connecting frame 32 is rotatably sleeved on the outside of the cylinder 31. A fixed cylinder 33 is fixedly connected to the side of the connecting frame 32 away from the cylinder 31. A middle block 34 is slidably sleeved on two adjacent fixed cylinders 33. A third spring is fixedly connected between the middle block 34 and the fixed cylinder 33. Control rods 35 are fixedly connected to both the upper and lower sides of the middle block 34. A control plate 36 is fixedly connected to the end of the control rod 35 away from the middle block 34. A middle rod 27 is fixedly connected to the side wall of the control plate 36. Two first connecting plates 28 are rotatably sleeved on both the upper and lower sides of the middle rod 27. A second connecting plate 29 is slidably sleeved on the end of the two first connecting plates 28 away from the middle rod 27. The second connecting plate 29 is rotatably connected to the connecting frame 32. First, because the rotating frame 13 and roller 17 are similar in structure to a real-life omnidirectional wheel, the roller 17 is constantly rotating during the movement of the sleeve 6. Furthermore, the rotating frame 13 and sleeve 6 move in parallel directions. Since the sleeve 6 and working head 5 are connected by a sliding connection, and the laser marking pattern is not regular, the movement of the working head 5 is also irregular. This leads to irregular movement of the sleeve 6, which follows the working head 5. Because the rotating frame 13 is always parallel to the movement of the sleeve 6, it continuously rotates relative to the sleeve 6. Ultimately, this causes the distance between the two nearest limiting grooves 15 of adjacent rotating frames 13 to constantly change. When the rollers 17 on both sides are at the same height, as the two rotating frames 13 move with the sleeve 6, they adaptively rotate their angles, changing the distance between adjacent rotating frames 13. At this time, the slide rods 30 are located at the lower ends of the limiting grooves 15 inside the rotating frames 13 on both sides. The first connecting plate 28 and the second connecting plate 29 can automatically rotate around the middle rod 27, thus automatically adapting to the distance between the two rotating frames 13. The first connecting plate 28 and the second connecting plate 29 then form a simple sealing operation on the gap between the two adjacent rotating frames 13, further reducing the possibility of splashing from the gap between the two rotating frames 13 onto the outside of the sleeve 6, thereby improving the overall protective effect of the sleeve 6. Therefore, the first connecting plate 28 and the second connecting plate 29 will automatically adjust to match the distance between the two rotating frames 13. Furthermore, during this process, when one of the rollers 17 moves to a higher position, i.e., when a height difference appears between two adjacent rollers 17, because the slide bar 30 is located at the lower end of the limiting groove 15, when one of the rollers 17 moves, the slide bar 30 on one side will disconnect from the lower end of the limiting groove 15 of the rotating frame 13 outside the lower roller 17. For example, with Figure 11 From the perspective of the left roller 17, when the left roller 17 is higher than the right roller 17, the left roller 17 drives the rotating frame 13 to move upward under the action of the higher left roller 17. The rotating frame 13 drives the slide rod 30, cylinder 31, first connecting plate 28, and second connecting plate 29 to move together with the left roller 17 through the limiting groove 15. The right slide rod 30 and the lower end of the limiting groove 15 on the outside of the right rotating frame 13 are disconnected, which can prevent the first connecting plate 28 and the second connecting plate 29 from colliding with the instant tea drink machine. Finally, the effect of automatic adjustment is achieved, which ensures the protection effect and prevents collision with the instant tea drink machine, thereby ensuring the coding quality. A cleaning component is fixedly installed inside the sleeve 6. The cleaning component includes a slide plate 19 that is slidably connected to the sleeve 6. A second spring 20 is fixedly connected between the slide plate 19 and the sleeve 6. A third connecting rod 21 is fixedly connected to the lower side of the slide plate 19. An arc plate 22 is fixedly connected to the side wall of the slide plate 19. During the up-and-down movement of the first connecting plate 28 and the second connecting plate 29, the second connecting plate 29 and the third connecting rod 21 abut against each other, which will drive the third connecting rod 21 to move upward. The third connecting rod 21 will drive the slide plate 19 to move upward. While the slide plate 19 stretches the second spring 20, it will drive the arc plate 22 to move up and down, thereby cleaning up any splashes that may stick to the inner wall of the sleeve 6, so that the sleeve 6 always maintains a suitable working state. Multiple telescopic rods 25 are fixedly connected inside the sleeve 6. The position and number of the multiple telescopic rods 25 are opposite to the arc plate 22. A triangular block 23 is fixedly connected to the lower side of the arc plate 22. A trapezoidal block 24 is fixedly connected to the side wall of the telescopic rod 25. A calibration head 26 is fixedly connected to the end of the telescopic rod 25. First, a return spring is fixedly connected to the inner wall of the calibration head 26 and the sleeve 6. Second, the calibration head 26 represents a coaxial vision system: a beam splitter guides a beam of measurement light (or another band of analysis light) and the processing laser to the workpiece along the same path, and then reflects it back to be received by the sensor. It can monitor in real time: plasma / thermal radiation: indirectly determine whether the energy is appropriate; surface morphology: using specific techniques (such as confocal or structured light), the depth and contour of the marking can be measured online and non-contactly. During the inspection process, the up-and-down moving arc plate 22 drives the triangular block 23 to move. The triangular block 23 and the trapezoidal block 24 abut against each other, which will drive the calibration head 26 to move back and forth, adjust the position of the calibration head 26, and thus better exert the monitoring effect.

[0015] In this invention, before the coding operation, the turntable 42 is rotated, which drives the lifting threaded rod 44 to rotate. The rotating lifting threaded rod 44 will drive the working arm 3 and the working head 5 to move up and down relative to the square cylinder 41 until the position of the working head 5 meets the working requirements. Then, the threaded rod 8 is rotated, which drives the rotating threaded plate 9, the first connecting rod 10, the second connecting rod 12, and the sleeve 6 to move up and down relative to the working head 5 until the position of the sleeve 6 meets the working requirements. This completes the preliminary adjustment operation. The working arm 3 and the working head 5 are then started to begin the coding operation. During the coding operation, the roller 17 abuts against the instant tea machine, and the first spring 18 is in a compressed state. During the coding operation, the roller 17 and the rotating frame 13 are similar to the structure of a caster wheel in real life. Therefore, the multiple rotating frames 13 are in a parallel state. The surface of the instant tea machine is uneven. Under the action of the roller 17, the lower end of the sleeve 6 will never abut against the instant tea machine, so that the sleeve 6 always maintains a good working condition, reduces the splash range, and thus maintains the coding quality. During the movement of sleeve 6, roller 17 is constantly rotating, and the movement direction of rotating frame 13 and sleeve 6 is parallel. Since the marking pattern is not regular, the movement of working head 5 and sleeve 6 is irregular. Furthermore, because rotating frame 13 is always parallel to the movement direction of sleeve 6, rotating frame 13 continuously rotates relative to sleeve 6. This ultimately causes the distance between the two nearest limiting grooves 15 of two adjacent rotating frames 13 to constantly change. When the rollers 17 on both sides are at the same height, as the two rotating frames 13 move with the sleeve 6, they adaptively rotate their angles, changing the distance between adjacent rotating frames 13. At this time, the slide rods 30 are located at the lower ends of the limiting grooves 15 inside the rotating frames 13 on both sides. Furthermore, the first connecting plate 28 and the second connecting plate 29 can automatically rotate around the middle rod 27, thus automatically adapting to the distance between the two rotating frames 13. The first connecting plate 28 and the second connecting plate 29 then form a simple sealing operation on the gap between the two adjacent rotating frames 13, further reducing the possibility of splashing from the gap between the two rotating frames 13 onto the outside of the sleeve 6, thereby improving the overall protective effect of the sleeve 6. Furthermore, during this process, when one of the rollers 17 moves to a higher position, i.e., when there is a height difference between two adjacent rollers 17, since the slide bar 30 is located at the lower end of the limiting groove 15, when one of the rollers 17 moves, the slide bar 30 on one side will disconnect from the lower end of the limiting groove 15 of the outer rotating frame 13 of the lower roller 17. This can prevent the first connecting plate 28 and the second connecting plate 29 from colliding with the instant tea machine, and ultimately achieve the effect of automatic adjustment, which ensures the protective effect and prevents collision with the instant tea machine, thereby ensuring the coding quality. During the up-and-down movement of the first connecting plate 28 and the second connecting plate 29, the second connecting plate 29 and the third connecting rod 21 abut against each other, which will drive the third connecting rod 21 and the slide plate 19 to move upward. While the slide plate 19 stretches the second spring 20, it will drive the arc plate 22 to move up and down, thereby cleaning up any splashes that may stick to the inner wall of the sleeve 6, so that the sleeve 6 always maintains a suitable working state. The up-and-down moving arc plate 22 drives the triangular block 23 to move. The triangular block 23 and the trapezoidal block 24 abut against each other, which drives the calibration head 26 to move back and forth, adjusting the position of the calibration head 26, thereby improving the monitoring effect.
