Description

Technical Field

[0001] This application relates to the field of marking technology, and more particularly to a marking device. Background Technology

[0002] Marking devices are used to create persistent markings such as serial numbers, codes, or QR codes on product surfaces to meet traceability and quality management needs. In mass production of automotive parts, metal pipes, and electronic product casings, marking devices often need to be used in rotation between multiple workstations to achieve multi-tasking with a single machine.

[0003] Existing marking devices mainly include handheld marking guns and track-assisted robotic arm marking systems. Handheld marking guns have a simple structure but rely on manual handling; track-assisted robotic arms use pneumatic or servo-driven mechanisms to move the marking head along a fixed track, which can reduce the operator's workload.

[0004] However, handheld jab guns are heavy due to the large weight of the engraving head, and the high frequency of operation causes serious physical exhaustion for the operator, making it difficult to meet the needs of batch continuous operation; while track-assisted robotic arms are limited by fixed tracks, and the equipment cannot be flexibly moved between multiple workstations, and the track laying cost is high and occupies a lot of space.

[0042] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0043] As described in the background section, existing marking devices mainly include handheld marking guns and track-assisted robotic arm marking systems. Handheld marking guns have a simple structure but rely on manual handling; track-assisted robotic arms use pneumatic or servo-driven mechanisms to move the marking head along a fixed track, reducing the operator's workload.

[0044] However, handheld jab guns are heavy due to the large weight of the engraving head, and the high frequency of operation causes serious physical exhaustion for the operator, making it difficult to meet the needs of batch continuous operation; while track-assisted robotic arms are limited by fixed tracks, and the equipment cannot be flexibly moved between multiple workstations, and the track laying cost is high and occupies a lot of space.

[0045] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0046] Reference Figures 1 to 3 This application provides a marking device, comprising: a moving component 100, a cantilever component 200, a marking component 300, and a positioning component 400. One end of the cantilever component 200 is disposed on the moving component 100. The cantilever component 200 is configured to be adjustable to a preset state under external force and automatically maintain the preset state when the external force is removed. The marking component 300 is disposed on the other end of the cantilever component 200 and is used to mark the target object. The positioning component 400 is disposed on the marking component 300 and is used to position the marking component 300.

[0047] Specifically, the movable component 100 is used to support the other functional components of the marking device and to enable the overall equipment to move within the work area. The movable component 100 can be constructed with a set of wheels at the bottom. One end of the cantilever component 200 is located on the movable component 100. The cantilever component 200 can flexibly change its spatial posture when driven by external force. The movable component 100 is equipped with a control system, which controls the operation of the movable component 100, the cantilever component 200, and the marking component 300. It also has a touch screen electrically connected to the control system for human-machine interaction. The touch screen is tilted to facilitate operation and is more ergonomic.

[0048] Furthermore, the connection between the movable component 100 and the cantilever component 200 can adopt a rotatable connection structure. The rotatable connection structure includes a mounting base fixedly disposed on the upper surface of the movable component 100 and a rotating shaft disposed at one end of the cantilever component 200. The rotating shaft passes through a shaft hole in the mounting base, allowing the cantilever component 200 to rotate relative to the movable component 100 about a vertical axis. One end of the cantilever component 200 is pivotally connected to the movable component 100 through this rotatable connection structure, while the other end of the cantilever component 200 extends away from the movable component 100.

[0049] During operation, the operator first moves the marking device to the vicinity of the target workpiece location using the moving component 100. Then, the operator applies an external driving force to the cantilever assembly 200, causing it to adjust its posture in space until the marking component 300 connected to the other end of the cantilever assembly 200 is roughly aligned with the marking area on the workpiece surface. Once the cantilever assembly 200 is adjusted to the preset state, the operator removes the external driving force, and the cantilever assembly 200 automatically maintains this preset posture. Subsequently, the operator precisely calibrates the position of the marking component 300 relative to the workpiece surface using the positioning component 400. After confirming the marking position is accurate, the operator starts the marking component 300 to perform the marking operation.

[0050] This embodiment utilizes the moving component 100 to transfer the marking device between different workstations, enabling a single device to serve multiple production stations. The cantilever component 200 is adjustable in posture under external force and automatically maintains its posture when the external force is removed. This allows the operator to apply force only during adjustment, eliminating the need for continuous force to maintain the cantilever component 200's posture after adjustment, thus reducing operator fatigue. The positioning component 400 positions the marking component 300, calibrating the relative position between the marking component 300 and the target object before marking, resulting in more accurate marking.

[0051] In some other possible embodiments, the moving component 100 may adopt a track-type moving platform structure. This track-type moving platform includes a platform body and track wheels disposed at the bottom of the platform body. The track wheels roll in contact with a pre-laid track on the ground, and the platform body moves along the extension direction of the track. The track-type moving platform is suitable for production line scenarios where workstations are arranged in a straight line. In this embodiment, the track-type moving platform enables the marking device to travel along a preset track, reducing the workload of the operator manually moving the equipment.

[0052] Reference Figure 2 and Figure 3 In some embodiments of this application, the cantilever assembly 200 includes: a horizontal adjustment component 210 and a height adjustment component 220. One end of the horizontal adjustment component 210 is rotatably connected to the moving assembly 100, and the horizontal adjustment component 210 can rotate about a first axis extending in a first direction. One end of the height adjustment component 220 is rotatably connected to the other end of the horizontal adjustment component 210, and the height adjustment component 220 can rotate about a second axis extending in the first direction. The other end of the height adjustment component 220 is connected to the marking assembly 300 for adjusting the height of the marking assembly 300.

[0053] Specifically, the horizontal adjustment component 210 is an arm-shaped structural member used to adjust the spatial position of the marking assembly 300 in the horizontal plane. One end of the horizontal adjustment component 210 is rotatably connected to the moving assembly 100, allowing the horizontal adjustment component 210 to swing about a first axis in the horizontal plane. The first axis extends along a first direction, which is the vertical direction (i.e.,...). Figure 2 and Figure 3 (Z-axis direction in the text). The height adjustment component 220 is an arm-shaped structural member used to adjust the vertical height of the marking assembly 300. One end of the height adjustment component 220 is rotatably connected to the other end of the horizontal adjustment component 210, allowing the height adjustment component 220 to swing about a second axis in the vertical plane, which also extends along the first direction. The other end of the height adjustment component 220 is connected to the marking assembly 300, and the swinging motion causes the marking assembly 300 to rise and fall vertically.

[0054] Understandably, the horizontal adjustment component 210's swing in the horizontal plane is a first-level adjustment, with a relatively large swing amplitude, belonging to coarse adjustment; while the height adjustment component 220's swing in the horizontal plane is a second-level adjustment, with a smaller swing amplitude, but more precise, belonging to fine adjustment.

[0055] Furthermore, one end of the horizontal adjustment component 210 may be provided with a first shaft hole, and the moving assembly 100 is provided with a first rotating shaft that mates with the first shaft hole. The first shaft hole is fitted onto the first rotating shaft, allowing the horizontal adjustment component 210 to rotate around a first axis. The other end of the horizontal adjustment component 210 is provided with a second rotating shaft, and one end of the height adjustment component 220 is provided with a second shaft hole. The second shaft hole is fitted onto the second rotating shaft, allowing the height adjustment component 220 to rotate around a second axis. The horizontal adjustment component 210 may adopt a hollow tubular structure to reduce its own weight while ensuring structural strength.

[0056] During use, when the operator needs to adjust the horizontal position of the marking assembly 300, the operator applies a horizontal force to the horizontal adjustment component 210, causing the horizontal adjustment component 210 to rotate relative to the moving assembly 100 in the horizontal plane around the first axis, thereby first moving the marking assembly 300 to a roughly horizontal area above the workpiece. Then, by rotating and adjusting the marking assembly 300, it can be moved to a more precise horizontal area.

[0057] Then, when the operator needs to adjust the vertical height of the marking assembly 300, the operator applies a vertical force to the height adjustment component 220, causing the height adjustment component 220 to swing about the second axis relative to the horizontal adjustment component 210 in the vertical plane, thereby driving the marking assembly 300 to rise or fall to a height position close to the workpiece surface.

[0058] In this embodiment, the rotation of the horizontal adjustment component 210 around the first axis and the rotation of the height adjustment component 220 around the second axis achieve precise adjustment of the marking component 300's position in the horizontal plane. The vertical height adjustment of the marking component 300 is achieved by the oscillation of the height adjustment component 220 around the second axis. The coordinated operation of these two components allows the marking component 300 to be flexibly positioned in both the horizontal and vertical planes. The horizontal adjustment component 210 employs a hollow tubular structure, which reduces its weight while ensuring structural strength, thus lowering the force required for the operator to drive the horizontal adjustment component 210 to rotate.

[0059] In some other possible embodiments, the horizontal adjustment component 210 can be configured as a multi-section telescopic arm structure. This multi-section telescopic arm structure includes a fixed arm and a movable arm. One end of the fixed arm is rotatably connected to the moving component 100, and the movable arm is slidably fitted inside the fixed arm, extending or retracting along the axial direction of the fixed arm. A locking member is provided between the fixed arm and the movable arm; when the movable arm extends to the desired length, the relative position of the movable arm and the fixed arm is locked by the locking member. This embodiment, through the multi-section telescopic arm structure, further expands the adjustment range of the horizontal adjustment component 210 in the horizontal plane.

[0060] Reference Figure 4 In some embodiments of this application, the height adjustment component 220 includes: a first hinge seat 221, a second hinge seat 222, a hinge rod 223, a slider 224, and a telescopic component 225. The first hinge seat 221 is rotatably connected to the horizontal adjustment component 210; the second hinge seat 222 is connected to the marking assembly 300; one end of the hinge rod 223 is hinged to the first hinge seat 221, and the other end is hinged to the second hinge seat 222; the slider 224 is slidably disposed on the hinge rod 223; one end of the telescopic component 225 is hinged to the first hinge seat 221, and the other end is hinged to the slider 224.

[0061] Specifically, the hinge rod 223 is a long strip-shaped connecting rod used to connect the first hinge seat 221 and the second hinge seat 222. The sliding member 224 is sleeved on the outside of the hinge rod 223 and can slide freely along the axial direction of the hinge rod 223. One end of the telescopic member 225 is hinged to the first hinge seat 221, and the other end of the telescopic member 225 is hinged to one end of the adjusting member 226. The other end of the adjusting member 226 is fixedly connected to the sliding member 224. The telescopic member 225 drives the adjusting member 226 to move through telescopic movement, and the adjusting member 226 drives the sliding member 224 to slide along the hinge rod 223.

[0062] Furthermore, one side of the first hinge seat 221 is rotatably mounted on the end of the horizontal adjustment component 210, and the other side of the first hinge seat 221 is provided with two spaced-apart opposing first side plates, with first hinge holes coaxially formed on the two first side plates. One end of the hinge rod 223 is provided with a first hinge shaft, which passes through both the first hinge holes on the two first side plates and the first through hole on the hinge rod 223, hinged to one end of the hinge rod 223 with the first hinge seat 221.

[0063] One side of the second hinge seat 222 is fixedly mounted on the marking assembly 300. The other side of the second hinge seat 222 is provided with two spaced-apart and opposite second side plates, and the two second side plates are coaxially provided with second hinge holes. The other end of the hinge rod 223 is provided with a second hinge shaft, which passes through the second hinge holes on the two second side plates and the second through hole on the hinge rod 223, hinged to the other end of the hinge rod 223 with the second hinge seat 222.

[0064] The sliding member 224 is constructed as a slider structure, with a groove in the middle. The inner wall of the groove slides in contact with the outer circumferential surface of the hinge rod 223, allowing the sliding member 224 to slide freely along the hinge rod 223. The adjusting member 226 can be constructed as a connecting rod structure. One end of the adjusting member 226 is fixedly connected to the sliding member 224, and the other end of the adjusting member 226 is hinged to the piston rod end of the telescopic member 225 via a third hinge shaft. The cylinder end of the telescopic member 225 is hinged to the first hinge seat 221 via a fourth hinge shaft.

[0065] During use, when the operator needs to raise the marking assembly 300, the operator controls the piston rod of the telescopic component 225 to extend outward. The piston rod pushes the adjusting component 226 to move. The adjusting component 226 drives the sliding component 224 to slide along the hinge rod 223 in a direction away from the first hinge seat 221. During the sliding process, the sliding component 224 drives the hinge rod 223 to rotate upward around the first hinge axis, so that the second hinge axis end of the hinge rod 223 is raised upward, and the marking assembly 300 is raised synchronously through the second hinge seat 222.

[0066] When the operator needs to lower the marking assembly 300, the operator controls the piston rod of the telescopic component 225 to retract inward. The piston rod pulls the adjusting component 226 to move. The adjusting component 226 drives the sliding component 224 to slide along the hinge rod 223 toward the direction close to the first hinge seat 221. During the sliding process, the sliding component 224 drives the hinge rod 223 to rotate downward around the first hinge axis, causing the second hinge axis end of the hinge rod 223 to descend, and the marking assembly 300 descends accordingly.

[0067] In this embodiment, the telescopic movement of the telescopic member 225 drives the adjustment member 226 to move. The adjustment member 226 causes the sliding member 224 to slide along the hinge rod 223. The sliding of the sliding member 224 causes the hinge rod 223 to rotate around the first hinge seat 221, thereby converting the linear motion of the telescopic member 225 into the oscillating motion of the hinge rod 223, thus realizing the height adjustment of the marking assembly 300. The adjustment member 226 is located between the telescopic member 225 and the sliding member 224, serving as an intermediate connection for power transmission and motion direction conversion, allowing the driving force of the telescopic member 225 to be transmitted to the sliding member 224 more smoothly. The telescopic member 225, as a driving element, can provide a stable and controllable driving force, making the height adjustment process smooth and reliable.

[0068] Reference Figure 2 and Figure 5 In some embodiments of this application, a station adjustment component 500 is also included, which is disposed between the cantilever component 200 and the marking component 300; the station adjustment component 500 is used to switch between the first station and the second station to adjust the position of the marking component 300.

[0069] Specifically, the station adjustment component 500 is positioned between the end of the cantilever assembly 200 and the marking assembly 300. The station adjustment component 500 can switch between the first station and the second station, specifically by causing the marking assembly 300 to change its position relative to the cantilever assembly 200, thereby changing the position of the marking assembly 300 in space.

[0070] This embodiment configures the workstation adjustment component 500 to switch between a first workstation and a second workstation, enabling the application to mark different parts of the vehicle according to different situations, greatly expanding the scope of application. Of course, this embodiment is not limited to a first and second workstation; it may also include a third and fourth workstation, etc. The number of workstations is not specifically limited and can be set according to actual conditions.

[0071] Reference Figure 1 and Figure 5 In some embodiments of this application, an angle compensation component 600 is provided between the workstation adjustment component 500 and the cantilever component 200. The angle compensation component 600 includes: a first compensation component 610 and a second compensation component 620. The first compensation component 610 is connected to the cantilever component 200 and can rotate around a third axis. The third axis extends along a second direction, which is perpendicular to the first direction. One end of the second compensation component 620 is rotatably connected to the first compensation component 610, and the other end is connected to the workstation adjustment component 500. The second compensation component 620 can drive the workstation adjustment component 500 to rotate around a fourth axis. The fourth axis extends along a third direction, which is perpendicular to both the first and second directions.

[0072] Specifically, the angle compensation component 600 is used to compensate for the angle deviation generated by the cantilever assembly 200 during attitude adjustment. The second direction refers to... Figure 1 In the Y-axis direction, the third direction refers to Figure 1 The X-axis direction in the diagram.

[0073] Furthermore, the first compensation component 610 includes a connecting seat 611 and a first compensation bushing 612 rotatably connected to the connecting seat 611. The first compensation bushing 612 is rotatable relative to the connecting seat 611 about a third axis. A connecting flange is provided on the side of the connecting seat 611 away from the first compensation bushing 612. The connecting flange is fixedly connected to the other end of the cantilever assembly 200 by bolts.

[0074] The second compensation component 620 includes a first compensation shaft 621 and a second compensation bushing 622 connected to each other. The first compensation shaft 621 is rotatably disposed inside the first compensation bushing 622, and the workstation adjustment component 500 is rotatably disposed inside the second compensation bushing 622. The second compensation bushing 622 can rotate relative to the first compensation shaft 621 about a fourth axis, thereby driving the workstation adjustment component 500 to rotate about the fourth axis.

[0075] In this embodiment, the marking assembly 300 achieves angle compensation in the second direction through the rotation of the first compensation component 610 around the third axis, and achieves angle compensation in the third direction through the rotation of the second compensation component 620 around the fourth axis. The two compensation directions are perpendicular to each other, enabling independent correction of angular deviations in different directions generated during the adjustment of the cantilever assembly 200. After angle compensation, the marking assembly 300 can be aligned with the workpiece surface in the correct posture, thereby improving marking accuracy.

[0076] In some other possible embodiments, an angle indicating dial can be provided between the first compensation component 610 and the second compensation component 620. This angle indicating dial includes an arc-shaped scale fixedly mounted on the first compensation component 610 and an indicating pointer fixedly mounted on the second compensation component 620. When the second compensation component 620 rotates relative to the first compensation component 610 about a third axis, the indicating pointer moves on the arc-shaped scale, indicating the current rotation angle value. This embodiment, through the setting of the angle indicating dial, allows the operator to intuitively read the angle compensation amount.

[0077] Reference Figure 1 and Figure 5 In some embodiments of this application, the workstation adjustment assembly 500 includes: a support frame 510 and a locking component 520. The support frame 510 is rotatably connected to the second compensation component 620, and the support frame 510 is used to fix the marking assembly 300. The locking component 520 is disposed between the support frame 510 and the second compensation component 620. The locking component 520 is used to switch between a locked state and an unlocked state. In the locked state, the support frame 510 and the second compensation component 620 are locked to each other. In the unlocked state, the support frame 510 can rotate relative to the second compensation component 620.

[0078] Specifically, the workstation adjustment assembly 500 includes a support frame 510 and a locking component 520. The support frame 510 is used to fix the marking assembly 300 and is rotatably connected to the second compensating bushing 622. The locking component 520 is disposed between the support frame 510 and the second compensating bushing 622, and can switch between a locked state and an unlocked state. When the locking component 520 is in the locked state, the support frame 510 and the second compensating bushing 622 are locked together, and the support frame 510 cannot rotate relative to the second compensating bushing 622. When the locking component 520 is in the unlocked state, the support frame 510 can rotate freely relative to the second compensating bushing 622.

[0079] During use, when it is necessary to switch the workstation of the marking component 300, the operator first operates the locking component 520 from the locked state to the unlocked state, that is, the operator pulls the locking pin out of the locking hole of the second compensating bushing 622, allowing the carrier frame 510 to rotate freely relative to the second compensating bushing 622. Then, the operator applies rotational force to the carrier frame 510, causing the carrier frame 510 to rotate around the rotation axis to the angular position corresponding to the target workstation. Finally, the operator inserts the locking pin into the locking hole corresponding to the target workstation, the locking component 520 switches back to the locked state, and the carrier frame 510 is locked at the target workstation.

[0080] This embodiment achieves the switching and locking of the marking assembly 300 between different workstations through the rotatable connection between the support frame 510 and the second compensating bushing 622, and the locking and unlocking switching of the locking component 520. In the locked state, the locking component 520 relatively fixes the support frame 510 and the second compensating bushing 622, ensuring the stability of the marking assembly 300's position during marking. In the unlocked state, the locking component 520 allows the support frame 510 to rotate freely, making the workstation switching operation convenient and quick.

[0081] In some other possible embodiments, the locking component 520 may employ a friction locking structure. The friction locking structure includes a friction plate and a clamping member. The friction plate is disposed at the rotatable connection between the support frame 510 and the second compensating bushing 622, and the clamping member passes through the support frame 510 and abuts against the friction plate. When the clamping member is tightened, it presses against the friction plate, generating friction between the friction plate and the second compensating bushing 622, thus locking the support frame 510 and the second compensating bushing 622 relative to each other. When the clamping member is loosened, the friction decreases, and the support frame 510 can rotate freely relative to the second compensating bushing 622. This embodiment, through the provision of the friction locking structure, allows the locking angle of the support frame 510 to be continuously adjusted.

[0082] Reference Figure 5 and Figure 6In some embodiments of this application, the support frame 510 has a rotating part 511, which is rotatably connected to the second compensating bushing 622; the locking component 520 includes: a first locking member 521, a second locking member 522, and a driving member 523. One end of the first locking member 521 is rotatably connected to the second compensating component 620 and is located on one side of the rotating part 511; one end of the second locking member 522 is rotatably connected to the second compensating component 620 and is located on the other side of the rotating part 511; the driving member 523... A moving member 523 is disposed between the first locking member 521 and the second locking member 522, and is used to drive the first locking member 521 and the second locking member 522 to open and close, so as to limit or release the rotation part 511; wherein, when the first locking member 521 and the second locking member 522 limit the rotation part 511, the locking member 520 is in a locked state; when the first locking member 521 and the second locking member 522 release the limit on the rotation part 511, the locking member 520 is in an unlocked state.

[0083] Specifically, the rotating part 511 can be constructed as a cylindrical boss structure protruding upward from the support frame 510, and the outer peripheral surface of the cylindrical boss structure is a cylindrical surface. The second compensating bushing 622 is provided with a circular groove or a circular through hole adapted to the cylindrical boss structure. The cylindrical boss structure is embedded in the circular groove or passes through the circular through hole, so that the support frame 510 can rotate relative to the second compensating bushing 622 about the central axis of the cylindrical boss structure.

[0084] The first locking member 521 and the second locking member 522 can be constructed as arc-shaped claw structures, with the inner arc surface of the claws matching the arc of the outer circumferential surface of the rotating part 511. One end of the first locking member 521 is hinged to the second compensating bushing 622 via a first hinge pin, and the first locking member 521 is located on one radial side of the rotating part 511. One end of the second locking member 522 is hinged to the second compensating bushing 622 via a second hinge pin, and the second locking member 522 is located on the other radial side of the rotating part 511, that is, the first locking member 521 and the second locking member 522 are arranged opposite each other in the radial direction of the rotating part 511. The driving member 523 can be a bidirectional telescopic cylinder, with the first piston rod end of the bidirectional telescopic cylinder hinged to the other end of the first locking member 521, and the second piston rod end of the bidirectional telescopic cylinder hinged to the other end of the second locking member 522.

[0085] During use, when it is necessary to switch the locking component 520 from the unlocked state to the locked state, the driving component 523 drives the first locking component 521 and the second locking component 522 to move towards each other. The first locking component 521 and the second locking component 522 approach the outer peripheral surface of the rotating part 511 from both sides until the inner arc surfaces of the first locking component 521 and the second locking component 522 are tightly fitted with the outer peripheral surface of the rotating part 511, clamping the rotating part 511 between them, and the support frame 510 cannot rotate relative to the second compensating bushing 622. At this time, the first locking component 521 and the second locking component 522 limit the rotating part 511, and the locking component 520 is in the locked state.

[0086] When it is necessary to switch the locking component 520 from the locked state to the unlocked state, the driving component 523 drives the first locking component 521 and the second locking component 522 to move away from each other. The inner arc surfaces of the first locking component 521 and the second locking component 522 disengage from the outer peripheral surface of the rotating part 511, releasing the clamping and limiting effect on the rotating part 511. The support frame 510 can then rotate freely relative to the second compensating bushing 622. At this time, the first locking component 521 and the second locking component 522 release the limiting effect on the rotating part 511, and the locking component 520 is in the unlocked state.

[0087] In this embodiment, the first locking member 521 and the second locking member 522 simultaneously clamp or release the rotating part 511 from both radial sides, respectively, thus achieving the switching between the locked and unlocked states of the locking component 520. When the first locking member 521 and the second locking member 522 clamp the rotating part 511, the locking force is symmetrically distributed on the outer circumferential surface of the rotating part 511, providing a balanced clamping force and reliably locking the support frame 510 in its current position. One end of each of the first locking member 521 and the second locking member 522 is rotatably connected to the second compensating bushing 622, so that the opening and closing actions of the first locking member 521 and the second locking member 522 are supported by the second compensating bushing 622, making the fulcrum of the opening and closing action stable and the action more reliable.

[0088] The driving component 523 is positioned between the first locking component 521 and the second locking component 522 and drives both components to move simultaneously, ensuring the synchronicity of their movements and preventing locking deviation or jamming caused by asynchronous movements. The inner arc surface of the arc-shaped pawl forms a surface contact with the outer peripheral surface of the cylindrical rotating part 511, increasing the contact area and providing greater locking friction under the same clamping force.

[0089] In some other possible embodiments, friction pads can be fixedly disposed on the inner arc surfaces of the arc-shaped claws of the first locking member 521 and the second locking member 522. The friction pads can be made of polyurethane elastomer or rubber, and are fixed to the inner arc surfaces of the arc-shaped claws by vulcanization bonding or riveting. When the first locking member 521 and the second locking member 522 clamp the rotating part 511, the friction pads are in direct contact with the outer peripheral surface of the rotating part 511. The high coefficient of friction of the polyurethane or rubber material increases the locking friction force, while elastic deformation makes the clamping force more evenly distributed on the outer peripheral surface of the rotating part 511. This embodiment improves the locking reliability of the locking component 520 and reduces wear on the outer peripheral surface of the rotating part 511 by using friction pads.

[0090] Reference Figure 2 and Figure 7 In some embodiments of this application, the marking cover 700 and the smoke treatment component 800 are further included. The marking cover 700 has a first channel 710 inside and a plurality of through holes 720 on its side wall. One end of the marking cover 700 is disposed on the support frame 510 and is correspondingly disposed with the marking component 300 so that the marking path of the marking component 300 passes through the first channel 710. The smoke treatment component 800 is disposed at the other end of the marking cover 700. The smoke treatment component 800 has a second channel 811 inside and the marking path of the marking component 300 passes through the second channel 811. The smoke treatment component 800 is used to discharge the smoke generated by the marking component 300 into the second channel 811.

[0091] Specifically, the marking cover 700 can be constructed as a cylindrical shell structure, with an upper connecting flange at the upper end and a lower connecting flange at the lower end. The upper connecting flange is fixedly connected to the support frame 510 by bolts, allowing the marking cover 700 to be suspended below the support frame 510. The marking assembly 300 is fixedly mounted on the support frame 510, with the marking head of the marking assembly 300 located above the support frame 510 or passing through a mounting hole in the support frame 510. The light outlet of the marking head and the upper port of the marking cover 700 are vertically opposite and spaced apart, with a gap between the marking head and the upper port of the marking cover 700.

[0092] The lower connecting flange at the bottom of the marking cover 700 is fixedly connected to the upper end of the fume treatment assembly 800 by bolts, so that the first channel 710 of the marking cover 700 and the second channel 811 of the fume treatment assembly 800 are vertically aligned and connected. During marking, the lower port of the fume treatment assembly 800 is in contact with or close to the surface of the workpiece to be marked, allowing the marking laser to pass through the second channel 811 and directly irradiate the workpiece surface. Several through holes 720 are formed on the side wall of the marking cover 700, connecting the first channel 710 to the external atmospheric environment.

[0093] During use, the operator moves the marking device to the workpiece position, adjusts the orientation of the marking component 300 so that the marking laser is aligned with the marking area on the workpiece surface, and brings the lower port of the fume treatment component 800 into contact with the workpiece surface. The marking laser emitted from the marking component 300 exits through the light outlet of the marking head, first passing through the gap between the upper port of the marking cover 700 and the marking head into the first channel 710, then through the first channel 710 into the second channel 811 of the fume treatment component 800, and finally through the second channel 811 to irradiate the workpiece surface, completing the marking operation.

[0094] During the marking process, the workpiece surface material vaporizes under laser irradiation, generating smoke. This smoke is first generated and accumulates inside the smoke treatment component 800. After the smoke treatment component 800 is activated, it collects and treats the smoke in the second channel 811, preventing the smoke from escaping upwards from the second channel 811 into the first channel 710. Simultaneously, the through-hole 720 on the side wall of the marking cover 700 connects the first channel 710 to the external atmosphere. If a small amount of smoke enters the first channel 710, external air enters through the through-hole 720 to dilute the smoke and assist in its discharge.

[0095] In this embodiment, the first channel 710 of the marking cover 700 and the second channel 811 of the fume treatment component 800 are vertically aligned and connected, allowing the marking laser emitted by the marking component 300 to pass sequentially through the first channel 710 and the second channel 811 before reaching the workpiece surface. The marking cover 700 and the marking component 300 are spaced apart, ensuring that the marking laser does not need to pass through any solid structure before entering the first channel 710, thus avoiding laser energy attenuation and optical path deviation, and ensuring that the marking laser reaches the workpiece surface with complete energy and an accurate optical path.

[0096] The lower port of the fume treatment component 800 is close to or in contact with the workpiece surface, allowing the fume generated during marking to be directly generated and collected within the fume treatment component 800. This treatment at the source of fume generation effectively prevents the fume from escaping upwards into the marking cover 700 or spreading into the external environment. The through-hole 720 on the side wall of the marking cover 700 connects the first channel 710 to the external atmosphere, preventing airflow disturbances caused by pressure discrepancies between the inside and outside of the marking cover 700 from affecting the stability of the marking laser. It also assists in the removal of any small amount of fume entering the first channel 710.

[0097] Reference Figure 2 and Figure 7In some embodiments of this application, the smoke treatment assembly 800 includes: a hood 810, an air blowing component 820, and an air suction component 830. The hood 810 has a second channel 811 inside and is connected to the marking cover 700. One side of the hood 810 has an air inlet 812 and the other side has an air outlet 813. The air blowing component 820 is located on one side of the hood 810 and is used to blow air into the air inlet 812 so that the smoke inside the second channel 811 flows to the air outlet 813. The air suction component 830 is located on the other side of the hood 810 and is used to suck air into the air outlet 813 so that the smoke is discharged through the air outlet 813 to the outside of the second channel 811.

[0098] Specifically, the fairing 810 can be constructed as a shell structure, with an upper mounting flange at the upper end of the shell. The upper mounting flange is fixedly connected to the lower end of the marking cover 700 by bolts, so that the second channel 811 of the fairing 810 communicates with the first channel 710 of the marking cover 700. An air inlet 812 is located on one side wall of the fairing 810, and an air outlet 813 is located on the other side wall of the fairing 810. The air inlet 812 and the air outlet 813 are arranged opposite each other in the horizontal direction. The blowing component 820 and the suction component 830 are respectively connected to the fan system 900, and the fan system 900 provides blowing and suction power.

[0099] In this embodiment, the blowing component 820 blows airflow into the second channel 811 from the air inlet 812, creating a directional airflow within the second channel 811 that flows from the air inlet 812 towards the air outlet 813. This directional airflow carries smoke towards the air outlet 813. The suction component 830 draws air into the second channel 811 through the air outlet 813, creating a negative pressure area at the air outlet 813 and actively extracting the smoke that has reached the air outlet 813. The combined action of blowing and suction ensures unidirectional directional flow of smoke within the second channel 811, preventing backflow of smoke within the second channel 811.

[0100] In some other possible embodiments, the top of the marking cover 700 is provided with a baffle plate, which is disposed on the top of the air blowing component 820. The air blowing port 821 of the air blowing component 820 is inclined upward and aligned with the baffle plate. When the airflow from the air blowing component 820 is blown out, it is changed to an inclined downward flow direction by the baffle plate and enters the interior of the second channel 811, thereby having a downward impact on the flue gas inside the second channel 811 and preventing the flue gas in the second channel 811 from extending upward into the interior of the first channel 710.

[0101] In some embodiments of this application, a gas cut-off protection component is also included, which is used to suspend the cantilever assembly 200 in a preset state in the event of a loss of control of the cantilever assembly 200.

[0102] Specifically, the air shortage protection component is installed in the power system of the cantilever assembly 200. The air shortage protection component is used to keep the cantilever assembly 200 suspended in a preset state in the event of loss of control of the cantilever assembly 200. That is, the air shortage protection component can automatically lock the cantilever assembly 200 in the attitude position at the moment of air shortage when the cantilever assembly 200 loses power control, so that the cantilever assembly 200 will not fall due to gravity or swing under the action of external force.

[0103] Furthermore, the air supply interruption protection assembly may include an air pressure detection unit and a locking actuator. The air pressure detection unit is installed in the air supply line of the cantilever assembly 200 to detect the air pressure value in the air supply line in real time. The locking actuator is installed at the joint of the cantilever assembly 200 and includes an elastic reset member and a braking member. The elastic reset member always applies a spring force toward the braking position to the braking member. When the air pressure in the air supply line is normal, the air pressure overcomes the spring force of the elastic reset member, causing the braking member to move away from the braking position; when the air pressure in the air supply line is abnormal or there is an air supply interruption, the elastic reset member releases its spring force to drive the braking member to actuate and lock the joint.

[0104] During use, when the air pressure in the air supply line of the cantilever assembly 200 is within the normal operating range, the brake is away from the braking position, and the joint of the cantilever assembly 200 can rotate freely, allowing the operator to adjust the posture of the cantilever assembly 200 normally. When the air supply line is interrupted or the air pressure value is lower than the preset threshold, the elastic reset component releases its elastic force to drive the brake to move, locking the joint at the current rotation angle, so that the cantilever assembly 200 as a whole remains in the posture at the moment of air interruption.

[0105] This embodiment, through the inclusion of an air shortage protection component, automatically locks the cantilever assembly 200 in its current posture when the power system of the cantilever assembly 200 experiences an air shortage or abnormal air pressure, preventing the cantilever assembly 200 from falling or swinging uncontrollably. The elastic reset component uses mechanical elasticity as the locking power source, eliminating the need for an external power source and ensuring reliable operation even in the event of a complete air shortage, thus allowing the cantilever assembly 200 to suspend in a preset state in the event of loss of control.
