Description

Technical Field

[0001] This invention relates to the field of automated production equipment technology, and in particular to a labeling device. Background Technology

[0002] In the packaging box production process, labels need to be affixed to the boxes. However, manual labeling makes it difficult to ensure that the labels are straight, flat, and smooth, affecting the appearance of the packaging box. In existing technology, a turntable mechanism can be used to affix labels to improve efficiency. The turntable mechanism has a turntable and fixed components rotatably mounted on it. For ease of operation, the packaging box is typically folded into a flat sheet and secured using the fixed components. Then, labels are affixed to the front and back of the packaging box using a suction nozzle.

[0003] However, the turntable is prone to vibration during rotation, and the fixed component tends to rotate around its own axis of rotation when it rotates with the turntable. This causes the fixed component to have an angle deviation when it reaches the work position that needs to be flipped, making it impossible for the fixed component to flip or the angle is incorrect after flipping, which affects the labeling operation. Summary of the Invention

[0004] The purpose of this invention is to provide a labeling device that ensures the rotating shaft does not rotate, thereby ensuring the stability of the fixing component during the rotation of the turntable.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A labeling device, comprising:

[0007] Machine tool;

[0008] A turntable mechanism is provided on the machine base. The turntable mechanism includes an anti-rotation ring and a turntable. The turntable is provided with multiple sets of fixing components spaced apart along the circumference. The fixing components are configured to fix the workpiece. The fixing components are rotatably connected to the turntable. The fixing components include a rotating shaft. The rotating shaft has an anti-rotation plane. When the fixing components rotate with the turntable, the anti-rotation plane slides against the anti-rotation ring.

[0009] At least two sets of labeling components are disposed on the machine tool. The at least two sets of labeling components are located on the outer periphery of the turntable and are arranged sequentially along the rotation direction of the turntable. The labeling components are configured to affix labels to the workpiece.

[0010] As an optional embodiment of the above-mentioned labeling device, the labeling device further includes an inspection component disposed downstream of at least two sets of labeling components. The inspection component includes an upper inspection member and a lower inspection member. When the fixing component passes between the upper inspection member and the lower inspection member, the upper inspection member and the lower inspection member can inspect the label on the workpiece.

[0011] As an optional embodiment of the above-mentioned labeling device, the labeling device further includes a pressure holding assembly, which includes an upper pressure holding head and a lower pressure holding head. The upper pressure holding head can move downward and press the label on the upper surface of the workpiece against the workpiece and hold pressure. The lower pressure holding head can move upward and press the label on the lower surface of the workpiece against the workpiece and hold pressure.

[0012] As an optional embodiment of the labeling device described above, the labeling device further includes a feeding assembly, which is disposed upstream of at least two sets of the labeling assemblies. The feeding assembly includes a feeding bin, a feeding beam, a feeding slider, and a feeding nozzle. Multiple workpieces are stacked inside the feeding bin. The top of the feeding bin is open. The feeding slider is slidably disposed on the feeding beam in a horizontal direction. The feeding nozzle is movably disposed on the feeding slider in a vertical direction and can adsorb the workpiece through the opening.

[0013] As an optional embodiment of the above-mentioned labeling device, the labeling device further includes a feeding assembly disposed downstream of at least two sets of the labeling assemblies. The feeding assembly includes a feeding beam, a feeding slider, and a feeding nozzle. The feeding slider is slidably disposed on the feeding beam in a horizontal direction, and the feeding nozzle is disposed on the feeding slider to adsorb the workpiece fixed by the fixing assembly.

[0014] As an optional solution for the above-mentioned labeling device, the labeling device further includes an opening and closing drive component. The fixing component includes a base and a cover plate. The base is fixedly connected to the rotating shaft. The base has a positioning groove for placing the workpiece. The cover plate is slidably disposed on the base and located above the base. The cover plate closes onto the base to press the workpiece into the positioning groove. The opening and closing drive component is disposed on the machine base. The output end of the opening and closing drive component can push and move the cover plate above the opening and closing drive component to drive the cover plate to rise and fall.

[0015] As an optional solution for the above labeling device, the fixing component further includes a guide post and a limiting member. One end of the guide post is fixedly connected to the cover plate, and the other end of the guide post passes through the base and is fixedly connected to the limiting member. The output end of the opening and closing drive is located below the limiting member and can push the limiting member.

[0016] As an optional solution for the above-mentioned labeling device, the turntable mechanism further includes a fixed platform and a drive assembly. The turntable is rotatably mounted on the fixed platform, and the anti-rotation ring is fixedly mounted on the fixed platform. The drive assembly includes a flipping drive component, which is rotatably mounted on the fixed platform. The flipping drive component has a drive groove, and the rotating shaft can abut against the inner wall of the drive groove so that the flipping drive component can drive the rotating shaft to rotate.

[0017] As an optional solution for the above-mentioned labeling device, the anti-rotation ring has an avoidance notch, and when the flipping drive drives the rotating shaft to rotate, the rotating shaft is located at the position of the avoidance notch.

[0018] As an optional embodiment of the labeling device described above, the fixed platform is provided with two sets of driving components, which are spaced apart circumferentially along the fixed platform, and the labeling component is provided upstream of the two sets of driving components and between the two sets of driving components.

[0019] The beneficial effects of this invention are:

[0020] This invention provides a labeling device. During the rotation of the turntable, the anti-rotation plane of the rotating shaft of the fixing component slides against the anti-rotation ring of the fixing table. The anti-rotation ring ensures that the rotating shaft will not rotate, thereby ensuring the stability of the fixing component during the rotation of the turntable. When the fixing component moves to a workstation that needs to be flipped, it can be flipped to a suitable angle, so that at least two sets of labeling components can affix labels to the workpiece fixed by the fixing component.

[0046] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0047] During the production of packaging boxes, labels need to be affixed. However, manual labeling makes it difficult to ensure that the labels are straight, flat, and smooth, affecting the appearance of the packaging boxes. In existing technology, labeling devices can be used to apply labels in order to improve efficiency.

[0048] In this embodiment, the workpiece is illustrated using a packaging box that requires labeling as an example. Figure 1 and Figure 2 As shown, the labeling device includes a machine base 1 and a turntable mechanism 2. The turntable mechanism 2 is disposed on the machine base 1 and includes a turntable 22. Multiple sets of fixing components 23 are spaced apart along the circumference of the turntable 22. The fixing components 23 are rotatably connected to the turntable 22. For ease of operation, the packaging box 100 is typically folded into a flat sheet and fixed using the fixing components 23. Then, the fixing components 23 rotate so that the side of the packaging box 100 to be labeled 101 faces the labeling nozzle 32, and the labeling nozzle 32 is used to apply the label 101 to the packaging box 100. It is worth noting that in this embodiment, after the packaging box 100 is fixed by the fixing components 23, the side facing upwards is called the front, and the side facing away is called the back.

[0049] However, the turntable 22 is prone to vibration during rotation, and the fixed component 23 is prone to rotate around its own rotation axis when rotating with the turntable 22. This causes the fixed component 23 to have an angle deviation when it reaches the work position that needs to be flipped, making it impossible for the fixed component 23 to flip or the angle is incorrect after flipping, which affects the operation of attaching the label 101.

[0050] like Figures 1-3 As shown, in order to solve the above problems, in this embodiment, the turntable mechanism 2 further includes an anti-rotation ring 211, and the fixing component 23 includes a rotating shaft 231. The rotating shaft 231 has an anti-rotation plane 2311. When the fixing component 23 rotates with the turntable 22, the anti-rotation plane 2311 slides against the anti-rotation ring 211.

[0051] During the rotation of the turntable 22, the anti-rotation plane 2311 of the rotating shaft 231 of the fixed component 23 slides and abuts against the anti-rotation ring 211 of the fixed table 21. The anti-rotation ring 211 can ensure that the rotating shaft 231 will not rotate, thereby ensuring the stability of the fixed component 23 during the rotation of the turntable 22. When the fixed component 23 moves to the work position that needs to be flipped, it can be flipped to a suitable angle, so as to attach the label 101 to the workpiece fixed by the fixed component 23.

[0052] like Figure 1As shown, in order to improve the accuracy of affixing labels 101 to packaging boxes 100, the labeling device further includes at least two sets of labeling components 3. The at least two sets of labeling components 3 are disposed on the machine base 1. The at least two sets of labeling components 3 are located on the outer periphery of the turntable 22 and are arranged sequentially along the rotation direction of the turntable 22. The labeling components 3 are configured to affix labels 101 to the workpiece.

[0053] For ease of setup, the labeling components 3 can only affix labels 101 to the upward-facing side of the packaging box 100. Therefore, when a set of labeling components 3 needs to affix labels 101 to the reverse side of the packaging box 100, the fixing component 23 needs to be rotated 180° before moving to the labeling component 3, so that the reverse side of the packaging box 100 faces upward. Then, the labeling component 3 can directly affix the label 101 to the packaging box 100. After the labeling is completed, the fixing component 23 can be rotated back to its initial state as needed to facilitate subsequent operations.

[0054] like Figure 4 and Figure 5 As shown, in order to improve the accuracy of the position of the packaging box 100, in this embodiment, the fixing component 23 further includes a positioning structure 233. The positioning structure 233 includes a positioning slider 2331, which is slidably disposed on the base 232. The cover plate 234 has a driving part 2341. During the process of the cover plate 234 covering the base 232 to press the packaging box 100 into the positioning groove 2321, the driving part 2341 can drive the positioning slider 2331 to approach the packaging box 100 and abut against one side edge of the packaging box 100.

[0055] The packaging box 100 is located in the positioning groove 2321. As the cover plate 234 slides towards the base 232, the driving part 2341 on the cover plate 234 can drive the positioning slider 2331 to approach the packaging box 100 and abut against one edge of the packaging box 100, thereby positioning the packaging box 100. When the cover plate 234 closes to the base 232, it can press the packaging box 100 in the positioning groove 2321, thereby ensuring that the packaging box 100 remains stable during the movement of the fixing component 23. Moreover, since the positioning process of the packaging box 100 does not require the operator to manually press the packaging box 100 to ensure its stability, there is no problem that the operator's hand will be removed from the positioning groove 2321, which would cause the packaging box 100 to be moved and affect the positional accuracy of the packaging box 100. This greatly improves the accuracy of the position of the packaging box 100 in the positioning groove 2321, ensuring the accuracy of the subsequent labeling 101 operation.

[0056] Understandably, to avoid affecting the labeling operation 101, both the base 232 and the cover 234 are provided with clearance structures 2342, and the clearance structures 2342 correspond to the positions on the packaging box 100 where the label 101 needs to be applied, so as to ensure that the labeling operation 101 can be completed without opening the cover 234 and the base 232. In this embodiment, the clearance structure 2342 can be a clearance groove or a clearance hole.

[0057] In this embodiment, the fixing component 23 includes two positioning structures 233. The sliding directions of the positioning sliders 2331 of the two positioning structures 233 are set at an angle. That is, the two positioning sliders 2331 can position the packaging box 100 in different directions to ensure the accuracy of the position of the packaging box 100 in the positioning groove 2321.

[0058] like Figure 6 As shown, the drive unit 2341 has a drive ramp 23411. During the process of the cover plate 234 covering the base 232, the drive ramp 23411 slides against the positioning slider 2331 and drives the positioning slider 2331 to abut against one side edge of the packaging box 100.

[0059] In this embodiment, when the cover plate 234 is above the base 232, the driving inclined surface 23411 is inclined in the direction away from the packaging box 100 in the downward direction. This arrangement enables the driving part 2341 to move downward, and the contact portion between the driving inclined surface 23411 and the positioning slider 2331 moves closer to the packaging box 100 in the horizontal direction, that is, the driving positioning slider 2331 moves closer to the packaging box 100.

[0060] In this embodiment, the positioning structure 233 further includes a fixed base 2332, which is fixedly connected to the base 232. The positioning slider 2331 is slidably disposed on the fixed base 2332. A first elastic element is disposed between the positioning slider 2331 and the fixed base 2332. The first elastic element is configured to drive the positioning slider 2331 to move away from the packaging box 100. The first elastic element facilitates the insertion of the packaging box 100 into the positioning groove 2321 or the removal of the packaging box 100 from the positioning groove 2321 when the cover plate 234 is not engaged with the base 232.

[0061] Furthermore, the fixing base 2332 is provided with a limiting block 2333. When the positioning slider 2331 moves away from the packaging box 100, it can abut against the limiting block 2333 to be limited by the limiting block 2333. The limiting block 2333 can prevent the positioning slider 2331 from disengaging from the fixing base 2332 under the drive of the first elastic element, and can also ensure that when the cover plate 234 is fastened to the base 232, the driving inclined surface 23411 can abut against the positioning slider 2331 to drive the positioning slider 2331 closer to the packaging box 100.

[0062] It is worth noting that, in order to achieve the above purpose, when the positioning slider 2331 abuts against the limiting block 2333, at least part of the positioning slider 2331 is located within the range of the driving inclined surface 23411 in the vertical direction.

[0063] In this embodiment, the positioning slider 2331 has a driven inclined surface 23311. During the process of the cover plate 234 being fastened to the base 232, the driven inclined surface 23311 of the positioning slider 2331 slides and abuts against the driving inclined surface 23411 of the driving part 2341 to prevent the sharp corner structure from scratching the driving inclined surface 23411. Specifically, the inclination direction and slope of the driven inclined surface 23311 are the same as those of the driving inclined surface 23411.

[0064] In this embodiment, the driving unit 2341 further includes a retaining surface 23412, which is connected to the driving inclined surface 23411 and is arranged in the vertical direction. After the positioning slider 2331 slides along the driving inclined surface 23411, it slides and abuts against the retaining surface 23412. The arrangement of the retaining surface 23412 ensures that the positioning slider 2331 no longer moves in the horizontal direction when the cover plate 234 is not fully engaged with the base 232, thus completing the positioning of the packaging box 100. At this time, the cover plate 234 can continue to approach the base 232 and engage with the base 232.

[0065] like Figure 7 As shown, in this embodiment, the labeling assembly 3 includes a connector 31, an application nozzle 32, and an application bracket 33. The application bracket 33 is mounted on the machine base 1. The connector 31 is vertically movable on the machine base 1 and can rotate around the vertical axis. The application nozzle 32 is fixedly mounted on the connector 31. By rotating, the connector 31 can adjust the relative angle between the label 101 and the packaging box 100. After the angle is adjusted to the correct position, the connector 31 moves downward to attach the label 101 to the packaging box 100. Then, the application nozzle 32 stops adsorbing, the connector 31 moves upward, and the turntable 22 continues to rotate, allowing the packaging box 100 to enter the next workstation.

[0066] Specifically, the labeling assembly 3 includes an angle adjustment member 34, a timing belt 35, a drive wheel 36, and a driven wheel 37. The angle adjustment member 34 is disposed on the attachment bracket 33 and is used to drive the drive wheel 36 to rotate. The timing belt 35 is tensioned by the drive wheel 36 and the driven wheel 37. The driven wheel 37 is sleeved outside the connector 31. The connector 31 and the driven wheel 37 are circumferentially locked and can move axially relative to each other.

[0067] The angle adjustment component 34 drives the driven wheel 37 to rotate via the driving wheel 36 and the synchronous belt 35. Since the driven wheel 37 is circumferentially locked to the connector 31, the connector 31 can rotate, thereby adjusting the relative angle between the label 101 and the packaging box 100. The connector 31 and the driven wheel 37 can move axially relative to each other, ensuring that the connector 31 can rise and fall, so that the application nozzle 32 can descend, thereby completing the label application operation.

[0068] In this embodiment, the driven wheel 37 includes a through hole, and a locking boss extending axially is provided on the inner wall of the through hole. The connecting member 31 passes through the through hole, and a locking groove 311 extending axially is provided on the side wall of the connecting member 31. The locking boss is slidably disposed in the locking groove 311. Through the cooperation between the locking boss and the locking groove 311, the connecting member 31 and the driven wheel 37 can only move relative to each other axially, and when the driven wheel 37 rotates, the connecting member 31 will also rotate accordingly.

[0069] Understandably, the labeling nozzle 32 needs to pick up the label 101 from the feeding position of the label 101 in order to attach the label 101 to the packaging box 100. In order to facilitate the picking up of the label 101 from the feeding position, the labeling assembly 3 also includes a rotating arm 38, which is rotatably mounted on the labeling bracket 33. The connector 31 is vertically movable on the rotating arm 38 and can rotate around the vertical axis.

[0070] like Figure 1 As shown, the labeling device also includes at least two sets of label supply components 9, which are arranged in a one-to-one correspondence with the labeling components 3. The rotating arm 38 rotates to have a label suction position 101 and a label application position 101. When the rotating arm 38 is in the label suction position 101, the application nozzle 32 suctions the label 101 from the label supply component 9. When the rotating arm 38 is in the label application position 101, the application nozzle 32 applies the label 101 to the workpiece.

[0071] The rotating arm 38, by rotating, moves the attachment nozzle 32 to the label supply assembly 9 to adsorb the label 101, and moves it above the packaging box 100. After the angle adjustment component 34 adjusts the relative angle between the label 101 and the packaging box 100, the connecting component 31 descends to attach the label 101 to the packaging box 100. To facilitate the supply of the label 101, in this embodiment, the label supply assembly 9 can be a feeder.

[0072] like Figure 2 , Figure 3 and Figure 8As shown, the turntable mechanism 2 also includes a fixed platform 21 and a drive assembly 24. The turntable 22 is rotatably mounted on the fixed platform 21, and the anti-rotation ring 211 is fixedly mounted on the fixed platform 21. The drive assembly 24 includes a tilting drive member 241, which is rotatably mounted on the fixed platform 21. The tilting drive member 241 has a drive groove 2411, and the rotating shaft 231 can abut against the inner wall of the drive groove 2411 so that the tilting drive member 241 can drive the rotating shaft 231 to rotate. The drive assembly 24 is fixedly mounted on the fixed platform 21. When the fixed assembly 23 rotates with the turntable 22 to the drive assembly 24, the rotating shaft 231 is engaged in the drive groove 2411, and the rotating shaft 231 can abut against the inner wall of the drive groove 2411. At this time, the tilting drive member 241 can drive the rotating shaft 231 to rotate, completing the tilting of the fixed assembly 23.

[0073] In this embodiment, the fixed platform 21 is provided with two sets of driving components 24, which are arranged at intervals along the circumference of the fixed platform 21, and labeling components 3 are provided upstream of the two sets of driving components 24 and between the two sets of driving components 24.

[0074] The drive assembly 24 located upstream in the rotation direction of the turntable 22 is used to flip the reverse side of the packaging box 100 to the upward direction, and the drive assembly 24 located downstream in the rotation direction of the turntable 22 is used to flip the reverse side of the packaging box 100 to the downward direction, so that the loading and unloading states of the packaging box 100 are consistent.

[0075] In this embodiment, two labels 101 need to be affixed to the front of the packaging box 100 and one label 101 needs to be affixed to the back of the packaging box 100. Therefore, the labeling device is provided with three sets of labeling components 3, and two sets of labeling components 3 are located upstream of two sets of driving components 24, and one set of labeling components 3 is located between two sets of driving components 24.

[0076] In this embodiment, the inner wall of the drive groove 2411 abuts against the anti-rotation plane 2311, and the rotating shaft 231 is driven to rotate through the anti-rotation plane 2311. The structure is simple and does not add any additional structure or cost.

[0077] In this embodiment, the rotating shaft 231 has two anti-rotation planes 2311, which are located on opposite sides of the rotating shaft 231 in the radial direction. The two anti-rotation planes 2311 ensure that the fixing assembly 23 remains stable after being flipped over by the anti-rotation ring 211.

[0078] Since the rotating shaft 231 has two anti-rotation planes 2311, when the rotating shaft 231 is inserted into the drive groove 2411, the inner wall of the drive groove 2411 simultaneously abuts against the two anti-rotation planes 2311, which can further improve the synchronization of rotation between the rotating shaft 231 and the flipping drive component 241, and avoid the relative sliding between the rotating shaft 231 and the drive groove 2411 from affecting the synchronization of the rotating shaft 231 and the flipping drive component 241.

[0079] In this embodiment, the rotating shaft 231 is a quadrangular prism, and two opposite sides of the quadrangular prism form two anti-rotation planes 2311. The quadrangular prism can also be fixedly connected to the base 232 without relative rotation, ensuring the accuracy of the angle when the fixing component 23 is flipped. In some embodiments, the rotating shaft 231 can also be a cylinder, with two anti-rotation planes 2311 symmetrically machined on the sidewalls of the cylinder. It can also cooperate with the drive groove 2411 and be driven by the flipping drive component 241.

[0080] In this embodiment, the flipping drive 241 is axially telescopically mounted on the fixed platform 21. When the fixed component 23 moves to the position of the drive component 24, the flipping drive 241 extends out to the drive groove 2411 where the rotating shaft 231 is inserted, and at this time the flipping drive 241 can drive the rotating shaft 231 to rotate.

[0081] like Figure 8 As shown, the drive assembly 24 includes a telescopic cylinder 242 and a rotary cylinder 243. The telescopic cylinder 242 is fixedly mounted on the fixed platform 21. The rotary cylinder 243 is connected to the piston rod of the telescopic cylinder 242. The flipping drive component 241 is connected to the piston rod of the rotary cylinder 243. The telescopic cylinder 242 and the rotary cylinder 243 can complete the telescopic and rotary movements of the flipping drive component 241.

[0082] In some embodiments, the drive groove 2411 extends to at least one end along a direction perpendicular to the rotation axis of the flip drive member 241 and penetrates the surface of the flip drive member 241. In this case, the opening of the drive groove 2411 on the surface of the flip drive member 241 is located on the rotation path of the fixing component 23. When the fixing component 23 rotates to the position of the drive component 24, the rotating shaft 231 enters the drive groove 2411 through one opening. After the flip drive member 241 drives the rotating shaft 231 to rotate, the rotating shaft 231 will again exit the drive groove 2411 through the aforementioned opening.

[0083] It is understandable that, due to the sliding contact between the anti-rotation plane 2311 and the anti-rotation ring 211, the rotating shaft 231 and the rotating drive 241 will interfere with the anti-rotation ring 211 when the rotating shaft 231 is rotated. Figure 3As shown, to solve the above problem, the anti-rotation ring 211 has a clearance notch 2111. When the flip drive 241 drives the rotating shaft 231 to rotate, the rotating shaft 231 is located at the clearance notch 2111. Since the clearance notch 2111 is small and the turntable 22 has already decelerated to a stop when the rotating shaft 231 moves to the clearance notch 2111, the fixed component 23 will not rotate on its own. Therefore, interference between the rotating shaft 231 and the flip drive 241 and the anti-rotation ring 211 can be avoided when the flip drive 241 drives the rotating shaft 231.

[0084] In this embodiment, the anti-rotation ring 211 is spaced apart from the fixed platform 21, and the anti-rotation plane 2311 slides against the side of the anti-rotation ring 211 that is away from the turntable 22. This structure ensures that there is a certain gap between the rotating shaft 231 and the fixed platform 21, so that the flipping drive component 241 will not contact the fixed platform 21 when it is sleeved outside the rotating shaft 231, thus facilitating the rotation of the rotating shaft 231.

[0085] like Figure 2 As shown, to ensure the stability of the turntable 22 during rotation, the turntable mechanism 2 also includes a support assembly 25. The support assembly 25 is mounted on the machine base 1 and includes a support column 251 and rollers 252. The support assembly 25 is located below the turntable 22. The height of the support column 251 is adjustable, and the rollers 252 are rotatably mounted on the support column 251 and roll against the turntable 22. By adjusting the height of the support column 251, the rollers 252 abut against the bottom surface of the turntable 22. During the rotation of the turntable 22, the rollers 252 always provide support, ensuring the stability of the turntable 22 during rotation.

[0086] like Figure 9 As shown, the turntable mechanism 2 includes multiple sets of support components 25, which are spaced apart circumferentially along the turntable 22. These multiple sets of support components 25 can support the turntable 22 from multiple positions, ensuring uniformity of support force while reducing the pressure on each set of support components 25, thus improving the stability of the turntable 22 and extending the service life of the support components 25.

[0087] To enable the turntable 22 to rotate, the turntable mechanism 2 further includes a rotation drive 26, which is located below the turntable 22 and is used to drive the turntable 22 to rotate. Furthermore, the rotation drive 26 is a rotary motor. To reduce the rotational speed of the turntable 22 and ensure stability, the turntable mechanism 2 also includes a reducer 27, which is driveably connected to the rotation drive 26 and the reducer 27, and the reducer 27 is driveably connected to the turntable 22.

[0088] like Figure 2 and Figure 10As shown, the turntable mechanism 2 also includes a locking component 28, which includes a locking frame 282 and a locking element 281. The locking frame 282 is fixedly mounted on the fixed platform 21. The fixed component 23 includes a support, and the rotating shaft 231 is rotatably mounted on the support. The support is fixedly mounted on the turntable 22. The support has a locking hole, and the locking element 281 can pass through the locking frame 282 and the locking hole in sequence to lock the fixed component 23 and the turntable 22.

[0089] Specifically, the locking member 281 is a rod, and a limiting rod 283 is connected to the upper end of the locking member 281. After the locking member 281 passes through the locking frame 282, the limiting rod 283 abuts against the locking frame 282. The limiting rod 283 can limit the locking member 281, ensuring that the locking member 281 can be inserted into the locking hole without abutting against the turntable 22. Moreover, if the limiting rod 283 abuts against the locking frame 282, it also indicates that the locking member 281 is at the correct depth in the locking hole, ensuring the locking effect.

[0090] Furthermore, the locking assembly 28 also includes a sensor 284, which is disposed on the locking frame 282 and is used to sense the locking member 281. Specifically, when the sensor 284 senses the locking member 281, it indicates that the locking member 281 has been locked, and the turntable 22 cannot rotate at this time; when the sensor 284 cannot sense the locking member 281, it indicates that the locking member 281 has been removed, and the turntable 22 can be started at this time.

[0091] Understandably, after affixing label 101, it is necessary to check label 101 on packaging box 100 to ensure that label 101 on packaging box 100 is in the correct position. For example... Figure 11 As shown, in order to achieve the above objective, the labeling device further includes an inspection component 4, which is disposed downstream of at least two sets of labeling components 3. The inspection component 4 includes an upper inspection member 41 and a lower inspection member 42. When the fixing component 23 passes between the upper inspection member 41 and the lower inspection member 42, the upper inspection member 41 and the lower inspection member 42 can inspect the label 101 of the packaging box 100.

[0092] Specifically, both the upper inspection component 41 and the lower inspection component 42 are vision components. They determine whether the position of the label 101 on the packaging box 100 is correct by taking a picture of the packaging box 100 and comparing the picture with a correct image. In this embodiment, the vision component can be a camera.

[0093] like Figure 12As shown, the labeling device also includes a pressure holding assembly 5, which includes an upper pressure holding head 51 and a lower pressure holding head 52. The upper pressure holding head 51 can move downward and press the label 101 on the upper surface of the packaging box 100 against the packaging box 100 and maintain pressure. The lower pressure holding head 52 can move upward and press the label 101 on the lower surface of the packaging box 100 against the packaging box 100 and maintain pressure.

[0094] Since the driving component 24 has flipped the fixing component 23 to its initial position, the upper surface of the packaging box 100 is now the front, and the lower surface is the back. By applying pressure, the label 101 can be more firmly attached to the packaging box 100, preventing the label 101 from falling off.

[0095] Furthermore, the upper pressure head 51 includes an upper slider 511, an upper elastic member 512, and an upper pressure holding member 513. The upper slider 511 is vertically movably disposed on the machine base 1. The upper pressure holding member 513 is slidably connected to the upper slider 511. The upper elastic member 512 is disposed between the upper pressure holding member 513 and the upper slider 511 and drives the upper pressure holding member 513 to move away from the upper slider 511.

[0096] When the upper pressure-holding member 513 abuts against the label 101 on the front of the packaging box 100, the upper elastic member 512 is compressed, causing the pressure of the upper pressure-holding member 513 on the label 101 to gradually increase. This ensures sufficient pressure while preventing excessive pressure at initial contact that could damage the label 101. In this embodiment, two upper pressure-holding heads 51 are provided to maintain pressure on two labels 101 respectively.

[0097] Similarly, the upper pressure head 51 includes a lower slider 521, a lower elastic element 522, and a lower pressure holding element 523. The lower slider 521 is vertically movable on the machine base 1. The lower pressure holding element 523 is slidably connected to the lower slider 521. The lower elastic element 522 is disposed between the lower pressure holding element 523 and the lower slider 521 and drives the lower pressure holding element 523 to move away from the lower slider 521. In this embodiment, one lower pressure holding head 52 is provided to hold pressure on one label 101.

[0098] like Figure 13 As shown, the labeling device also includes a feeding component 6, which is located upstream of at least two sets of labeling components 3. The feeding component 6 includes a feeding bin 61, a feeding beam 62, a feeding slider 63, and a feeding nozzle 64. Multiple packaging boxes 100 are stacked inside the feeding bin 61. The top of the feeding bin 61 is open. The feeding slider 63 is slidably disposed on the feeding beam 62 in the horizontal direction. The feeding nozzle 64 is moved vertically on the feeding slider 63 and can adsorb the packaging boxes 100 through the opening.

[0099] The feeding bin 61 can store multiple packaging boxes 100 at the same time. The feeding nozzle 64 picks up the packaging box 100 through the opening at the top of the feeding bin 61. Then, the feeding slider 63 moves the feeding nozzle 64 to the top of the fixing component 23 by sliding. The feeding nozzle 64 then descends to place the packaging box 100 on the fixing component 23 and fix it in place.

[0100] Furthermore, the feeding assembly 6 also includes a feeding bracket 65 and a slide table 66. The slide table 66 is provided with multiple feeding bins 61. The slide table 66 is slidably disposed on the feeding bracket 65 in the horizontal direction so that each feeding bin 61 can move to the bottom of the feeding beam 62 and be picked up by the feeding suction nozzle 64.

[0101] Because multiple feeding bins 61 are provided, once all the packaging boxes 100 in one feeding bin 61 have been sucked out by the feeding nozzle 64, the other feeding bins 61 can be moved below the feeding beam 62 by the sliding table 66. The feeding nozzle 64 can then continue to suck up packaging boxes 100, ensuring the operating rate and efficiency of the labeling device. Specifically, to ensure that each feeding bin 61 can move below the feeding beam 62, the moving direction of the feeding slider 63 is set at an angle to the moving direction of the sliding table 66.

[0102] Furthermore, the feeding assembly 6 also includes a lifting member 67, which is vertically movable on the feeding bracket 65. The bottom of the feeding bin 61 is provided with a clearance opening 611. The lifting member 67 can move up and down through the clearance opening 611 and inside the feeding bin 61 to adjust the height of the packaging box 100.

[0103] The lifting component 67 is fixed in the horizontal direction. When the feeding bin 61 moves with the slide table 66 to below the feeding beam 62, the lifting component 67 is located below the feeding bin 61. When the lifting component 67 rises, it passes through the clearance opening 611 and abuts against the lowest packaging box 100 in the feeding bin 61, thereby pushing all the packaging boxes 100 upward so that the highest packaging box 100 is close to or moves out of the opening, making it easier for the feeding nozzle 64 to pick up the packaging box.

[0104] like Figure 1 and Figure 4 As shown, the labeling device also includes an opening and closing drive component 8. The fixing component 23 includes a base 232 and a cover plate 234. The base 232 is fixedly connected to the rotating shaft 231. The base 232 has a positioning groove 2321 for placing the workpiece. The cover plate 234 is slidably disposed on the base 232 and located above the base 232. The cover plate 234 covers the base 232 to press the workpiece into the positioning groove 2321. The opening and closing drive component 8 is disposed on the machine base 1. The output end of the opening and closing drive component 8 can push and move to the cover plate 234 above the opening and closing drive component to drive the cover plate 234 to rise and fall.

[0105] By setting an opening and closing drive 8, each fixed component 23 that moves above the opening and closing drive 8 can be opened, thereby facilitating the feeding component 6 to move the packaging box 100 between the cover plate 234 and the base 232 of the fixed component 23. Specifically, when the cover plate 234 and the base 232 are opened, the feeding nozzle 64 descends to move the packaging box 100 to the height between the cover plate 234 and the base 232. Then, the feeding slider 63 moves horizontally to move the packaging box 100 between the cover plate 234 and the base 232. At this time, the feeding nozzle 64 descends to make the packaging box 100 abut against the base 232. The feeding nozzle 64 stops adsorbing, allowing the packaging box 100 to fall onto the base 232. At this time, the feeding nozzle 64 is removed, and the opening and closing drive 8 descends to make the cover plate 234 close onto the base 232.

[0106] like Figure 1 As shown, the machine 1 has a loading station 11, the loading component 6 is set at the loading station 11, and the loading station 11 is provided with an opening and closing drive component 8 to facilitate opening the fixing component 23.

[0107] Furthermore, the fixing assembly 23 also includes a guide post 235 and a limiting member 236. One end of the guide post 235 is fixedly connected to the cover plate 234, and the other end of the guide post 235 passes through the base 232 and is fixedly connected to the limiting member 236. The output end of the opening and closing drive member 8 is located below the limiting member 236 and can push the limiting member 236. The guide post 235 can provide guidance for the relative movement between the cover plate 234 and the base 232, ensuring that the cover plate 234 can accurately cover the base 232. The limiting member 236 can, on the one hand, prevent the cover plate 234 from moving too far and causing the guide post 235 to detach from the base 232, and on the other hand, ensure that the pushing force of the opening and closing drive member 8 on the cover plate 234 is evenly applied to the cover plate 234, preventing the cover plate 234 from deflecting.

[0108] Furthermore, the fixing component 23 also includes a second elastic element 237, which is disposed between the limiting member 236 and the base 232. The second elastic element 237 is configured to drive the limiting member 236 away from the base 232. The second elastic element 237 enables the cover 234 to close onto the base 232 and provides a certain holding force, so that the cover 234 and the base 232 will not open when moved or flipped, ensuring the stability of the packaging box 100.

[0109] like Figure 14 As shown, in order to improve the efficiency of the labeling device, the labeling device also includes a feeding assembly 7, which is located downstream of at least two sets of labeling assemblies 3. The feeding assembly 7 includes a feeding beam 71, a feeding slider 72 and a feeding nozzle 73. The feeding slider 72 is slidably disposed on the feeding beam 71 in the horizontal direction, and the feeding nozzle 73 is disposed on the feeding slider 72 to adsorb the workpiece fixed by the fixing assembly 23.

[0110] Understandably, an opening / closing drive 8 is also needed below the unloading component 7 to open and close the fixing component 23. Conversely to the loading operation of the packaging box 100, during unloading, the opening / closing drive 8 needs to lift the cover plate 234, then the unloading nozzle 73 descends and suctions the packaging box 100. As the unloading slider 72 moves horizontally, the packaging box 100 moves out of the base 232. The other end of the unloading beam 71 is a collection component or subsequent workstation, thus completing the unloading of the packaging box 100.

[0111] like Figure 1 As shown, the machine 1 has a feeding station 12, the feeding component 7 is set at the feeding station 12, and the feeding station 12 is also equipped with an opening and closing drive component 8 to facilitate opening the fixing component 23.

[0112] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
