Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to a quick-change label-absorbing head structure and labeling equipment. Background Technology

[0002] In the product manufacturing process, to achieve full-process tracking and quality control, labeling equipment is usually needed to affix labels to the surface of products (such as printed circuit boards, PCBs, etc.). As the core component of the labeling equipment, the suction head must be precisely matched with the shape and size of the label to be affixed to ensure stable and reliable label suction and affixing, and to avoid problems such as label detachment or misalignment.

[0003] However, existing nozzle replacement structures mostly adopt a single-station design, requiring manual intervention when replacing nozzles. The working nozzle must first be removed from the connected structure, and then the new nozzle must be manually installed. The entire operation process is cumbersome and time-consuming, which seriously interrupts the continuous operation of the production line and cannot keep up with the pace of high-speed automated production. Summary of the Invention

[0004] The main objective of this invention is to propose a quick-change label head structure and labeling device, aiming to solve the technical problem of low replacement efficiency when changing the label head in related technologies.

[0005] To achieve the above objectives, the present invention proposes a quick-change label head structure, comprising: A base, wherein the base is provided with at least two storage stations; At least two suction head modules, each suction head module is located within one of the storage stations, and each suction head module has a first connecting portion; The material handling module includes a drive connector and a suction head connector connected to the drive end of the drive connector. The suction head connector has a second connector that can be detachably engaged with the first connector. The drive connector can drive the suction head connector to move between each of the storage stations so that the second connector can be connected to the first connector in any of the storage stations. The detachment module has a portion of its structure movably mounted on the base, and the detachment module is used to separate the first connecting part from the second connecting part.

[0006] In one embodiment, the suction head module includes a suction head; the first connecting portion includes a release block and a protrusion, the release block being sleeved on one end of the suction head, and the protrusion being disposed on one end of the suction head; the second connecting portion includes a hook portion and a magnetic suction portion, the magnetic suction portion having a movable groove, and the hook portion being rotatably located within the movable groove; each of the release blocks having a magnetic element, the magnetic suction portion being connected to the magnetic element; and the protrusion engaging with the hook portion.

[0007] In one embodiment, the hook portion includes two hook arms, and a space is formed between the two hook arms for limiting each of the suction heads. The two hook arms are respectively engaged with the protrusion. The magnetic suction portion has pivot holes at opposite ends, and a pivot is formed between the two hook arms. The pivot passes through the pivot holes.

[0008] In one embodiment, the detachment module includes at least one auxiliary detachment component and a limiting plate. The limiting plate is movably located above the base and covers part of the structure of each of the storage stations. Each of the auxiliary detachment components is located within the storage station and is detachably connected to the first connecting portion.

[0009] In one embodiment, the first connecting portion includes a release block, the release block having at least one release hole, each of the auxiliary release components being provided corresponding to one release hole and being snapped into one release hole.

[0010] In one embodiment, each of the storage stations is provided with a limiting groove, and the limiting plate is provided with at least two limiting holes, each limiting hole corresponding to a limiting groove; one end of the base is provided with at least one fastener, and the limiting plate is provided with at least one oblong hole, each of the fasteners being movably limited within the oblong hole.

[0011] In one embodiment, the quick-change label head structure further includes a driving component, which is located on the side of the base facing away from the limiting plate, and the driving end of the driving component is connected to the base; the driving component can drive the base to move, thereby driving the fastener to move along the extension direction of the waist-shaped hole, so that each of the limiting holes is fully connected to each of the limiting grooves.

[0012] In one embodiment, the suction head module further includes a suction head and an elastic element, wherein the elastic element is respectively sleeved on the suction head and connected to one end of the first connecting portion; And / or, the suction head module further includes a suction head, a guide pin, and a guide sleeve, the guide sleeve being sleeved on the suction head, the outer peripheral wall of the suction head having a guide hole, and the guide pin passing through the guide hole and being connected and fixed to the guide sleeve.

[0013] In one embodiment, the quick-change label head structure further includes a detection module located at one end of the base and configured to reduce the deviation of the label head after replacement.

Multiple suction head modules can be pre-installed in the station, avoiding temporary adjustments during replacement. The drive connector moves the suction head connector, enabling automatic switching of the suction head modules without manual handling or alignment. The movable structure that detaches the module ensures the smoothness of the separation process between the suction head module and the material handling module, preventing damage to the connection during separation. This configuration significantly improves the efficiency of suction head replacement. The automated movement of the drive connector and the assisted separation of the detachment module shorten the replacement operation time. It also improves the accuracy of suction head replacement; the cooperation structure between the first and second connecting parts, combined with the limiting effect of the storage station, reduces the error of manual alignment. Furthermore, it enhances the versatility and flexibility of the entire structure, allowing multiple suction head modules to adapt to different specifications of standard parts, meeting diverse operational needs through switching. Finally, it reduces the intensity of manual operation; the automated connection and separation process reduces manual intervention steps, improving the safety and stability of the operation.

[0023] This invention proposes a quick-change structure for the label suction head 1000.

[0024] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the quick-change label head structure 1000 includes a base 1, at least two label head modules 4, a material picking module, and a detachment module 3. The base 1 is provided with at least two storage stations 11. Each label head module 4 is confined within a storage station 11, and each label head module 4 has a first connecting portion. The material picking module includes a drive connector and a label head connector 2 connected to the drive end of the drive connector. The label head connector 2 has a second connecting portion that can be detachably engaged with the first connecting portion. The drive connector can drive the label head connector 2 to move between each storage station 11 so that the second connecting portion can be connected to the first connecting portion in any storage station 11. A portion of the detachment module 3 is movably disposed on the base 1, and the detachment module 3 is used to separate the first connecting portion from the second connecting portion.

[0025] In this embodiment, the quick-change label head structure 1000 can be applied to food and beverage packaging production lines, printed circuit boards, 3C products, automotive parts, and other scenarios, without limitation. The base 1 provides an installation carrier. Each storage station 11 contains one label head module 4. The number of storage stations 11 is not limited; it can be two, three, or more. The size and specifications of the label head modules 4 stored in different storage stations 11 can also vary. The first connecting part is used to achieve a detachable connection with the second connecting part in the material handling module, and also cooperates with the storage station 11 of the base 1 to position the label head module 4 within the storage station 11. The material handling module is used to install and remove the label head 41. The drive connector provides power to the label head connector 2. The label head connector 2 is used to install and remove the label head module 4 within the storage station 11. One end of the label head connector 2 is configured to connect to the drive end of the drive connector. The drive connector can be a motor, cylinder, robotic arm, etc., without limitation. The second connecting part is used to cooperate with the first connecting part to achieve a reliable connection between the material handling module and the suction head module 4. It is understood that the connection between the first and second connecting parts can be achieved through snap-fit, magnetic attraction, or plug-in engagement. In one embodiment, the first connecting part is an outwardly protruding elastic hook with a barb structure at the end; the second connecting part is a groove adapted to the hook, with a limiting step on the inner wall of the groove that cooperates with the barb. The driving connector drives the suction head connector 2 to press down, causing the hook to contract under pressure and slide into the groove, where the barb engages with the limiting step to achieve connection; the push rod of the disengagement module 3 pushes the elastic end of the hook upward, causing the barb to disengage from the limiting step, thereby separating the two. In another embodiment, a permanent magnet is embedded in the first connecting part, and a magnetically conductive metal block is embedded in the second connecting part; alternatively, permanent magnets with opposite polarities are embedded in the first and second connecting parts, achieving connection through magnetic attraction. The separation module 3 can be equipped with an electromagnetic coil, which generates a magnetic field with opposite polarity to the permanent magnet after being energized, weakening the magnetic attraction and causing the two to separate; alternatively, a pushing mechanism can be provided to overcome the magnetic force through mechanical pushing to complete the separation. The above two configuration methods are not limited. The separation module 3 is used to separate the first connecting part from the second connecting part. The separation module 3 separates the first connecting part from the second connecting part through mechanical pushing, magnetic field reversal, or fork-like movement. In one embodiment, the separation module 3 uses a mechanical pushing method, with a push rod movably inserted through the bottom of the storage position 11 of the base 1. The lower end of the push rod is connected to a cylinder or electromagnet drive assembly. When separation is required, the drive assembly drives the push rod upward, and the top of the push rod acts on the bottom of the suction head module 4, overcoming the connection force between the first and second connecting parts through upward pushing, thus separating the two. In another embodiment, the disengagement module 3 is operated by a fork. The fork is hinged to the base 1 or the suction head connector 2 via a pivot. One end of the fork extends to the mating point between the first connecting part and the second connecting part, and the other end is connected to the linkage drive mechanism.When separation is required, the linkage drive mechanism drives the shift fork to swing around the pivot. The action end of the shift fork moves the mating parts of the connecting structure such as the hook and pin, breaking the locking or plugging relationship and achieving separation.

[0026] It should be noted that the process of the quick-change label head structure 1000 provided by the present invention is as follows: When the label head connector 2 needs to cooperate with the label head module 4 in the storage station 11, the label head connector 2, under the action of the drive connector, descends to above the storage station 11, and the second connecting part is aligned with the first connecting part through positioning. Subsequently, the drive connector further drives the label head connector 2 to press down, ensuring that the second connecting part and the first connecting part are reliably connected. After the connection is completed, the label head module 4 is firmly fixed on the label head connector 2, so that it can move to the working position with the material picking module for operation. When it is necessary to replace the label head module 4, the disengagement module 3 is activated, which applies force according to a preset method to separate the first connecting part from the second connecting part. The separated label head module 4 remains in the storage station 11, while the label head connector 2 returns to the initial state, ready to perform the next material picking operation.

[0027] The quick-change label head structure 1000 provided by this invention, through the combination of a base 1, at least two label head modules 4, a material handling module, and a disengagement module 3, can solve the problems of low replacement efficiency, complex operation, and easy positioning deviation in traditional label head replacement. Specifically, the base 1 is provided with at least two storage stations 11 for limiting at least two label head modules 4 respectively. Each label head module 4 is equipped with a first connecting part. The material handling module includes a drive connector and a label head connector 2. The second connecting part of the label head connector 2 can be detachably engaged with the first connecting part of the label head module 4. The drive connector can drive the label head connector 2 to move between each storage station 11, so that the second connecting part can selectively and accurately connect with the first connecting part in any storage station 11. Part of the structure of the disengagement module 3 is movably disposed on the base 1. When it is necessary to replace the label head module 4, the disengagement module 3 can apply force to the first connecting part and the second connecting part in the connected state to achieve stable separation between the two. Through the coordinated operation of the above structures, the storage station 11 of the base 1 provides a stable foundation for the placement and positioning of the suction head module 4. Multiple suction head modules 4 can be pre-installed in the station, avoiding temporary adjustments during replacement. The drive connector moves the suction head connector 2, enabling automatic switching of the suction head module 4 without manual handling or alignment. The movable structure of the detachment module 3 ensures the smoothness of the separation process between the suction head module 4 and the material handling module, preventing damage to the connection during separation. The above configuration significantly improves the replacement efficiency of the suction head 41. The automated movement of the drive connector and the assisted separation of the detachment module 3 shorten the replacement operation time. It also improves the accuracy of suction head replacement. The cooperation structure between the first and second connection parts, combined with the limiting effect of the storage station 11, reduces the error of manual alignment. It enhances the versatility and flexibility of the entire structure. Multiple suction head modules 4 can be adapted to different specifications of standard parts, and diverse operational needs can be met by switching. It reduces the intensity of manual operation. The automated connection and separation process reduces manual intervention steps, improving the safety and stability of the operation.

[0028] In one embodiment of the present invention, the suction head module 4 includes a suction head 41, a first connecting part including a release block 42 and a protrusion 43, the release block 42 being sleeved on one end of the suction head 41, and the protrusion 43 being disposed on one end of the suction head 41; the second connecting part including a hook part 21 and a magnetic suction part 22, the magnetic suction part 22 having a movable groove 22a, and the hook part 21 being rotatably located in the movable groove 22a; each release block 42 having a magnetic element, the magnetic suction part 22 being connected to the magnetic element; and the protrusion 43 being engaged with the hook part 21.

[0029] In this embodiment, combined with Figure 2 and Figure 3The hook portion 21 is used to achieve axial rigid contact and limiting with the suction head 41. The hook portion 21 has hook arms 211, and the number of hook arms 211 can be two, three, or more. Each hook arm 211 encloses a space that limits the suction head 41. It can be understood that the hook portion 21 is rotatably disposed in the movable groove 22a of the magnetic suction portion 22. After the magnetic suction portion 22 is attracted to the magnetic component, the hook portion 21 rotates around the pivot point, and the end of the hook portion 21 forms a rigid engagement with the protrusion 43 of the suction head 41, thereby applying a limiting constraint to the suction head 41 axially. The hook portion 21 and the movable groove 22a can be rotatable in the form of a pivot hinge or a torsion spring pivot. In one embodiment, a torsion spring is sleeved on the pivot of the hook portion 21, one end of the torsion spring is engaged with the inner wall of the movable groove 22a, and the other end is engaged with the outer wall of the hook portion 21. The torsion spring provides a continuous preload, driving the hook portion 21 to maintain a tendency to rotate towards the protrusion 43 of the suction head 41. This ensures that after the magnetic suction portion 22 is attracted to the magnetic component, the hook portion 21 can automatically rotate and abut against the protrusion 43. When it is necessary to detach, the external pushing force can overcome the torsion spring preload, causing the hook portion 21 to rotate in the opposite direction and reset. The magnetic suction portion 22 is used to achieve rapid pre-positioning with the suction head 41. It can be understood that the magnetic suction portion 22 includes two magnetic blocks and a connecting block. The connecting block is circular, and a magnetic block is provided at each of the opposite ends of the connecting block. A movable groove 22a is formed between the two magnetic blocks, and the hook portion 21 is confined within the movable groove 22a. The magnetic blocks can be in the form of magnets, electromagnets, etc., and the type of magnet can be neodymium iron boron permanent magnets, ferrite permanent magnets, etc., which can be selected according to specific needs. The connection between the suction head 41 and the release block 42 can be achieved through interference fit, threading, welding, etc. In one embodiment, the inner diameter of the release block 42 is slightly smaller than the outer diameter of the end of the suction head 41, and the release block 42 is tightly fitted onto one end of the suction head 41 by pressure assembly. In another embodiment, the end of the suction head 41 is provided with an external thread, and the inner diameter of the release block 42 is provided with a matching internal thread, and the two are connected by screwing. One end of the suction head 41 protrudes to form a protrusion 43, and the outer diameter of the protrusion 43 is slightly larger than the outer diameter of the suction head 41, so that when the suction head connector 2 is connected to the suction head 41, the outer wall of the protrusion 43 can abut against the hook portion 21. It should be noted that the protrusion 43 can be integrally formed or otherwise protruding from one end of the suction head 41, and the protrusion 43 is located above the release block 42. The release block 42 can be integrally formed or welded to the outer wall of the suction head 41. The release block 42 is equipped with a magnetic component. The type of magnetic component can be set with reference to the type of magnetic suction part 22. The magnetism of the magnetic component and the magnetism of the magnetic suction part 22 are reciprocal. The release block 42 can be connected to the magnetic component by means of bonding, welding, direct positioning, etc., which are not limited here. The magnetic component can be arranged in a ring along the circumference of the release block 42, or it can be arranged in a circle or a square, and connected to one side of the release block 42.

[0030] In one embodiment of the present invention, the hook part 21 includes two hook arms 211, and a space is formed between the two hook arms 211 for limiting each suction head 41. The two hook arms 211 are respectively engaged with the protrusion 43. The magnetic suction part 22 has a rotating shaft hole 22b at its opposite ends, and a rotating shaft is formed between the two hook arms 211. The rotating shaft passes through the rotating shaft hole 22b.

[0031] In this embodiment, combined with Figure 3 and Figure 5 To further enhance connection stability, the two hook arms 211 of the hook part 21 are symmetrically distributed, forming a limiting space between them that matches the protrusion 43 of the suction head 41. After the magnetic suction part 22 and the magnetic component of the release block 42 complete the adsorption and pre-positioning, the two hook arms 211 rotate synchronously around the pivot hole 22b, and their ends form a symmetrical snap-fit ​​engagement with the two sides of the protrusion 43 of the suction head 41, applying bidirectional constraint to the suction head 41 from both radial and axial directions to prevent the suction head 41 from shifting or falling off during operation. The pivot holes 22b at opposite ends of the magnetic suction part 22 form a clearance-fit hinge structure with the rotating ends of the two hook arms 211, providing a stable rotation fulcrum for the hook arms 211. Furthermore, each hook arm 211 has a rotating section 211a and an abutting section 211b connected together. The rotating section 211a is rotatably connected to the magnetic suction part 22, and one end of the rotating section 211a is bent to form the abutting section 211b, which engages with the outer wall of the protrusion 43. The rotating section 211a is connected to the auxiliary release part 31. The rotating section 211a and the abutting section 211b can be connected by integral molding, welding, or other methods. Both the rotating section 211a and the abutting section 211b are L-shaped, and a rotating shaft passes through the connection between the rotating section 211a and the abutting section 211b. Understandably, when the suction head connector 2 needs to replace the suction head 41 it is connected to, the suction head connector 2 descends to the storage station 11 under the action of external force and cooperates with the auxiliary release member 31 of the storage station 11. At this time, the auxiliary release member 31 pushes the rotating section 211a, causing the rotating section 211a to rotate, and at the same time driving the abutment section 211b to rotate synchronously, releasing the axial abutment constraint on the protrusion 43 of the suction head 41.

[0032] In one embodiment of the present invention, the detachment module 3 includes at least one auxiliary detachment component 31 and a limiting plate 32. The limiting plate 32 is movably located above the base 1 and covers part of the structure of each storage station 11. Each auxiliary detachment component 31 is located in the storage station 11 and is detachably connected to the first connecting part.

[0033] In this embodiment, combined with Figure 1The auxiliary release component 31 is used to separate the suction head 41 from the suction head connector 2. The number of auxiliary release components 31 is not limited and can be one, two, etc. The auxiliary release component 31 can take the form of an auxiliary pin, a compression spring and push rod, an electromagnetic coil, etc. In one embodiment, the auxiliary release component 31 can be an elastic buckle, with the first connecting part being a slot. The buckle engages with the slot to achieve connection. During separation, the buckle is opened or disengaged from the slot by external force, causing the first connecting part to separate from the second connecting part. In another embodiment, the release component has a built-in permanent magnet, and the first connecting part is made of magnetic material. The two are connected by magnetic attraction. During separation, separation is achieved by applying a reverse magnetic force or external force to overcome the magnetic attraction force. The limiting plate 32 is used to achieve reverse positioning of the suction head module 4 during separation. It can limit the top or side of the suction head module 4 during separation to prevent the suction head module 4 from moving synchronously with the suction head connector 2. It is understood that the limiting plate 32 can be a translational limiting plate 32, a flip-type limiting plate 32, etc. In one embodiment, the limiting plate 32 is connected to the base 1 via a slide rail and can be translated horizontally. When the suction head module 4 needs to be replaced, the limiting plate 32 moves along the slide rail to open the storage station 11, facilitating the docking of the suction head connector 2. When separated, the limiting plate 32 moves back to its original position, covering the top of the suction head module 4 to achieve limiting. In another embodiment, the limiting plate 32 is connected to the base 1 via a hinge and can be flipped around the hinge. After the suction head module 4 is installed in the storage station 11, the limiting plate 32 flips downward to cover the top of the station. When separated, it remains in a flipped closed state to limit, and when replaced, it flips upward to open.

[0034] In one embodiment of the present invention, the first connecting part includes a release block 42, the release block 42 having at least one release hole 421, each auxiliary release member 31 being provided with a release hole 421 and being snapped into the release hole 421.

[0035] In this embodiment, to enhance the separation force, the release block 42 is integrated into the first connecting part of the suction head module 4. At least one release hole 421 is formed on the release block 42. The auxiliary release member 31 is correspondingly embedded and locked within the release hole 421, forming a stable mechanical connection. When separation is required, the driving connector moves the suction head connector 2 upwards, or the matching driving structure of the release module 3 drives the auxiliary release member 31 to apply downward force. Simultaneously, the limiting plate 32 forms a reverse limiting on the suction head module 4, causing the auxiliary release member 31 to apply a downward pulling force to the release block 42 through the release hole 421, thereby forcing a relative displacement between the first connecting part and the second connecting part, releasing their connection. It is understood that the shape of the release hole 421 of the release block 42 can be circular, square, or other geometric shapes adapted to the auxiliary release member 31 to ensure that the auxiliary release member 31 can be accurately locked in and achieve a stable connection. The number of release holes 421 corresponds to the number of auxiliary release members 31, and can be one or more, with the specific number adjusted according to the needs of the actual application scenario. When the auxiliary release member 31 is inserted into the release hole 421, its end forms a tight fit with the inner wall of the release hole 421, thereby limiting the displacement of the release block 42 during the separation process and preventing displacement or loosening caused by external force.

[0036] In one embodiment of the present invention, each storage station 11 is provided with a limiting groove, and the limiting plate 32 is provided with at least two limiting holes 322, each limiting hole 322 corresponding to a limiting groove; one end of the base 1 is provided with at least one fastener 12, and the limiting plate 32 is provided with at least one waist-shaped hole 321, and each fastener 12 is movably limited within the waist-shaped hole 321.

[0037] In this embodiment, combined with Figure 4The shape of the limiting groove is adapted to the shape of each suction head 41 so that the suction head 41 can be limited and disengaged from the limiting groove. It can be understood that the shape of the limiting hole 322 is adapted to the shape of the limiting groove. When the limiting plate 32 moves under the action of external force, the waist-shaped hole 321 slides along the axial direction of the fastener 12 to realize the translation of the limiting plate 32. When the limiting plate 32 covers the storage station 11, the corresponding limiting hole 322 overlaps with the limiting groove, forming a circumferential wrapping and limiting of the disengagement block 42 of the suction head 41; when the limiting plate 32 moves to expose the storage station 11, the limiting hole 322 aligns with the limiting groove, releasing the limiting constraint on the disengagement block 42 of the suction head 41, ensuring that the suction head connector 2 can smoothly dock with the suction head 41 in the storage station 11. To ensure the stability of the switching of the limiting plate 32, a fastener 12 at one end of the base 1 passes through the oblong hole 321 in the limiting plate 32. The long axis of the oblong hole 321 limits the movement trajectory of the fastener 12, thus constraining the limiting plate 32 to move only in a straight line along the long axis of the oblong hole 321. This ensures that the movement path of the limiting plate 32 is precise and controllable when switching between covering and avoiding the storage station 11, preventing deviation and jamming. It is understood that the number of fasteners 12 is not limited; it can be one, two, or more. The number of fasteners 12 matches the number of oblong holes 321, with each fastener 12 corresponding to one oblong hole 321. The form of the fastener 12 can be a bolt, pin, etc., and is not limited here.

[0038] In one embodiment of the present invention, the quick-change structure 1000 for the suction head also includes a driving member 5. The driving member 5 is disposed on the side of the base 1 facing away from the limiting plate 32, and the driving end of the driving member 5 is connected to the base 1. The driving member 5 can drive the base 1 to move, thereby driving the fastener 12 to move along the extension direction of the waist-shaped hole 321, so that each limiting hole 322 is fully connected to each limiting groove.

[0039] In this embodiment, combined with Figure 4To achieve automated alignment between the limiting plate 32 and the limiting groove and improve quick-change efficiency, the drive component 5 is installed on the side of the base 1 facing away from the limiting plate 32. The drive end is rigidly connected to the base 1, and the linear driving force output by the drive component 5 can be directly transmitted to the base 1, causing the base 1 to reciprocate linearly in a preset direction, providing the power basis for the alignment of the limiting hole 322 and the limiting groove. It can be understood that the type of drive component 5 can be a cylinder, servo motor, electric push rod, etc., which can be set according to specific needs. The fastener 12 on the base 1 is movable within the oblong hole 321 of the limiting plate 32. The long axis of the oblong hole 321 limits the sliding trajectory of the fastener 12. When the drive component 5 moves the base 1, the fastener 12 slides synchronously along the long axis of the oblong hole 321, which not only provides precise guidance for the movement direction of the base 1 and prevents the base 1 from deviating, but also limits the displacement distance of the base 1 through the stroke of the oblong hole 321 to prevent excessive movement that could lead to alignment failure. It should be noted that when the suction head connector 2 is engaged with the suction head module 4, the suction head connector 2 descends into the limiting groove of the storage station 11. The hook part 21 and the magnetic suction part 22 of the suction head connector 2 are respectively connected to the protrusion 43 and the release block 42 in the suction head module 4. At this time, the limiting hole 322 and the limiting groove are fully connected. When the suction head connector 2 needs to be disassembled from the suction head module 4, the suction head connector 2 descends into the limiting groove of the storage station 11. The auxiliary release part 31 of the limiting groove passes through the release hole 421 of the release block 42, pushing open the snap-fit ​​force between the hook part 21 and the protrusion 43, causing the suction head connector 2 to separate from the release block 42. Then, the suction head connector 2 continues to rise under the action of the driving connector. At this time, because the periphery of the limiting hole 322 covers part of the limiting groove, the suction head module 4 is subject to the reverse constraint of the limiting plate 32 and cannot move synchronously with the suction head connector 2, thereby achieving the separation of the two. At this time, the drive unit 5 starts again, driving the base 1 to move along the extension direction of the waist-shaped hole 321, causing the limiting hole 322 to be misaligned with the limiting groove, and the limiting plate 32 to cover part of the structure of the storage station 11 again, ensuring that the suction head module 4 is stably restricted in the storage station 11, and avoiding displacement or tipping due to external interference.

[0040] In one embodiment of the present invention, the suction head module 4 further includes a suction head 41 and an elastic member 44, wherein the elastic member 44 is respectively sleeved on the suction head 41 and connected to one end of the first connecting portion; And / or, the suction head module 4 also includes a suction head 41, a guide pin 46 and a guide sleeve 45. The guide sleeve 45 is sleeved on the suction head 41. A guide hole is opened on the outer peripheral wall of the suction head 41. The guide pin 46 passes through the guide hole and is connected and fixed to the guide sleeve 45.

[0041] In this embodiment, combined with Figure 5To buffer the impact after the release block 42 detaches from the suction head connector 2, an elastic element 44 is fitted onto the suction head 41 and connected to one end of the release block 42. This allows the elastic element 44 to absorb impact energy through its own elastic deformation during suction head replacement, converting rigid impact into elastic buffering force. Simultaneously, the elastic restoring force enables the suction head 41 to quickly reset, preventing the impact load from being transmitted to the release block 42 and the suction head connector 2. Each suction head 41 is equipped with an elastic element 44. It is understood that the elastic element 44 can be in the form of a spring, such as a light-load spring, a stainless steel compression spring, or a polyurethane spring; no limitation is made here. The connection between one end of the elastic element 44 and the release block 42 can be welding, bonding, or other methods, while the other end of the elastic element 44 abuts against the guide sleeve 45 in the next embodiment.

[0042] Combination Figure 5 To prevent the suction head 41 from rotating, a guide sleeve 45 is fitted onto the outer wall of the suction head 41. The suction head 41 has a guide hole that penetrates one of its cross-sections. The shape of the guide hole can be oblong, elongated, etc., and is not limited here. The cooperation between the guide pin 46 and the guide hole provides additional guidance for the axial movement of the suction head 41, making the lifting and lowering process of the suction head 41 smoother and further improving the smoothness of the quick-change action.

[0043] In one embodiment of the present invention, the quick-change label head structure 1000 further includes a detection module 6, which is located at one end of the base 1 and is configured to reduce the deviation of the label head 41 after replacement.

[0044] In this embodiment, combined with Figure 6 To reduce deviations after replacing the suction head 41, the detection module 6 is used to detect the deviation of the suction head 41, improving the operational accuracy after quick replacement. The detection module 6 can take the form of an industrial camera and light source module, a laser displacement sensor, a high-precision probe, and a pressure sensor. In one embodiment, the detection module 6 is in the form of a laser displacement sensor, which is installed on one side of the base 1, with the laser emission end aligned with the side wall or adsorption end face of the suction head 41. The sensor can emit a laser beam and calculate the distance by receiving the time difference or phase difference of the reflected laser. In another embodiment, the detection module 6 uses a high-precision probe and a pressure sensor. The probe is installed on a telescopic mechanism at one end of the base 1, with the probe tip made of wear-resistant ceramic material, and the pressure sensor integrated into the probe tail. After the suction head 41 is replaced, the telescopic mechanism drives the probe to extend, so that the probe tip contacts the standard positioning point of the suction end of the suction head 41. The pressure sensor detects the contact pressure to ensure stable contact between the probe and the suction head 41. By recording the extension and horizontal displacement of the probe, the positional deviation of the suction head 41 is calculated. The control system adjusts the attitude of the suction head 41 according to the deviation value, and after compensation, the probe retracts. The detection module 6 here is preferably in the form of an industrial camera, and can be configured according to specific needs.

[0045] The present invention also proposes a labeling device, which includes the label suction head quick-change structure 1000 described above. The specific structure of the label suction head quick-change structure 1000 is as described in the above embodiments. Since the labeling device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0046] It is understood that the labeling equipment includes a drive connector that connects to the suction head connector 2 in the quick-change label head structure 1000. The drive connector can be in the form of a robotic arm, motor, or bracket; here, a robotic arm is used as an example. The robotic arm connects to the suction head connector 2, enabling it to perform a series of quick-change actions, such as switching, lowering and docking, and raising and disengaging the suction head 41 between different storage stations 11. The end effector of the robotic arm can be connected to the suction head connector 2 using a rigid flange to ensure smooth and undisturbed force transmission during movement, further guaranteeing the positional accuracy of the suction head 41 during replacement. This configuration, using the quick-change label head structure 1000, allows the labeling equipment to automatically disassemble and install the suction head 41 without manual intervention when switching between different label sizes or maintaining and replacing the suction head 41, significantly reducing changeover time.
