Description

Technical Field

[0001] This invention relates to the field of automated marking technology, and more specifically, to a marking system and method for marking digital sleeves. Background Technology

[0002] Laser marking technology has been widely used in the marking of various industrial products due to its advantages such as clear, permanent, efficient, and non-contact marking. For tubular or sleeve-shaped workpieces, it is usually necessary to mark scale lines, characters, or codes at specific angles on the circumferential surface, which places high demands on the consistency of the workpiece's posture after loading.

[0003] However, the relevant technology has at least one of the following problems: the existing sleeve-type workpiece marking system is prone to posture deviation during the conveying and positioning process, making it difficult to continuously guarantee the marking position accuracy. Summary of the Invention

[0004] The technical problem solved by this invention is that the existing sleeve-type workpiece marking system is prone to posture deviation during the conveying and positioning process, making it difficult to continuously guarantee the marking position accuracy.

[0005] To address the aforementioned problems, this invention provides a marking system for marking digital sleeves. The marking system includes an inlet end, an outlet end, and a track connecting the inlet end and the outlet end. The marking system further includes: a first adjusting mechanism located at the inlet end, used to receive a horizontally positioned digital sleeve and adjust it from a horizontal to a vertical position; a second adjusting mechanism located to one side of the first adjusting mechanism, used to adjust the angle of the vertically positioned digital sleeve around its axis to a first preset angle; a transport trolley located at one end of the track near the inlet end, used to transport the digital sleeve to the outlet end; and a marking positioning mechanism located at the outlet end, equipped with an ejection mechanism for engaging with the digital sleeve to disengage it from the transport trolley. When the ejection mechanism engages with the digital sleeve, the angle of the digital sleeve around its axis is the first preset angle.

[0006] Compared with existing technologies, the technical effects achieved by this solution are as follows: The first adjustment mechanism uniformly flips horizontal sleeves with different postures into a vertical state, providing a stable benchmark for circumferential angle adjustment; the second adjustment mechanism adjusts the angle of the vertical sleeve around the axis to a first preset angle, achieving preliminary circumferential positioning; the conveyor car completes high-speed transport from the inlet to the outlet; the marking and positioning mechanism uses an ejection mechanism to smoothly detach the sleeve from the conveyor car and enter the marking station at a preset angle. Each mechanism has a clear division of labor and works in sequence, gradually adjusting the sleeve to the target posture through multi-stage posture correction, effectively solving the problem of inaccurate marking position caused by posture deviation on the production line.

[0007] In one embodiment of the present invention, the digital sleeve includes a first end and a second end disposed opposite to each other. The horizontal state includes a forward state and a reverse state. In the forward state, the first end of the digital sleeve faces a first direction, and in the reverse state, the first end of the digital sleeve faces a second direction opposite to the first direction. The first adjustment mechanism includes: a first rotating arm disposed on the test platform at the feed end; a first gripper disposed at one end of the first rotating arm for gripping the digital sleeve; and a first sensor for detecting whether the digital sleeve is in the forward or reverse state. When the first gripper grips the digital sleeve in the forward state and drives the digital sleeve to rotate around a first rotation direction, the digital sleeve is adjusted to a vertical state. When the first gripper grips the digital sleeve in the reverse state and drives the digital sleeve to rotate around a second rotation direction opposite to the first rotation direction, the digital sleeve is adjusted to a vertical state.

[0008] Compared with existing technologies, the technical effects achieved by this solution are as follows: The first sensor automatically detects whether the digital sleeve is in a forward or reverse orientation, and controls the first rotating arm to rotate in different directions based on the detection result. This ensures that regardless of the sleeve's horizontal orientation when entering the system, it can be uniformly adjusted to a vertical position. This solution achieves adaptive forward and reverse rotation without manual intervention or additional reversing devices, improving the automation and compatibility of the feeding process.

[0009] In one embodiment of the present invention, the digital sleeve has a positioning hole on its body and a first opening at its first end; the second adjustment mechanism includes: a second rotating arm, which is installed at the feed end and located on one side of the platform to be tested; an elastic positioning member, which is installed at one end of the second rotating arm and includes multiple claws and a clamp on the outer periphery of the multiple claws, the outer diameter formed by the multiple claws corresponding to the first opening, and the clamp being used to limit the opening range of the multiple claws; and a second sensor, which is installed at the feed end and located on one side of the second adjustment mechanism, and is used to locate the positioning hole; wherein, when the laser emitted by the second sensor matches the positioning hole, the angle of the digital sleeve around its axis is a first preset angle.

[0010] Compared with existing technologies, the technical effects achieved by this solution are as follows: Multiple claws of the elastic positioning element extend into the first opening of the sleeve and restrict the opening amplitude with clamps. This reliably supports the inner wall of the sleeve to transmit rotational driving force while preventing damage to the inner wall due to excessive supporting force, achieving non-destructive clamping and rotational drive. Simultaneously, a second sensor detects the positioning holes on the sleeve body; rotation stops when the laser aligns with the positioning holes, achieving automatic coarse positioning of the sleeve around its axis, providing an accurate reference for subsequent fine positioning.

[0011] In one embodiment of the present invention, the feed end is provided with a third rotating arm, which is located above the transfer vehicle. One end of the third rotating arm is provided with a suction cup that mates with the second end. The transfer vehicle includes: a mounting base mounted on a track; a positioning seat mounted on the mounting base, the positioning seat having a positioning space for mates with the first end, a positioning post on the inner wall of the positioning space, and a mating hole communicating with the positioning space; and a telescopic post mounted on the feed end, the telescopic post being provided corresponding to the first opening, and the telescopic post mates with the first opening to allow the digital sleeve to be fitted onto the telescopic post. The first end has a first positioning notch that mates with the positioning post, the first end including a first top surface forming the first positioning notch and a first inclined surface, the first inclined surface abutting against the positioning post. When the first top surface abuts against the positioning post, the angle of the digital sleeve around its axis is a first preset angle.

[0012] Compared with existing technologies, the technical effects achieved by this solution are as follows: The mechanical engagement between the positioning post on the positioning seat and the first positioning notch at the first end of the sleeve enables circumferential positioning of the sleeve on the transport vehicle; the suction cup of the third rotating arm adsorbs the second end of the sleeve and drives its rotation, causing the first top surface to finally abut against the positioning post, achieving precise angle locking of the sleeve on the transport vehicle. The telescopic post plays an auxiliary guiding and centering role during the positioning process, ensuring that the sleeve accurately enters the positioning space. This solution further refines the coarse positioning, and the two-stage progressive adjustment significantly reduces angular errors.

[0013] In one embodiment of the present invention, a second opening is provided at the second end, and a first opening is connected to the second opening. A second positioning notch is provided at the first end to cooperate with the ejection mechanism. The first end includes a second top surface and a second inclined surface forming the second positioning notch. An elastic pin is provided above the marking positioning mechanism, facing the second opening. The ejection mechanism includes: a mounting base, which is disposed on the telescopic mechanism at the discharge end to drive the mounting base to move up and down. The mounting base is also provided with a first positioning plate that cooperates with the second top surface; a fixing column, which is installed above the mounting base and facing the first opening. The end of the fixing column is provided with a third opening that cooperates with the elastic pin, and the lower end of the fixing column is provided with a positioning liner that cooperates with the first opening; and an elastic fork, which is sleeved on the mounting base. The elastic fork is provided with a second positioning plate that cooperates with the second inclined surface. A return spring is connected between the elastic fork and the mounting base to subject the second positioning plate to an elastic force away from the first positioning plate.

[0014] Compared with existing technologies, the technical effects achieved by this solution are as follows: By extending the fixed post into the first opening, the third opening at the end of the fixed post can engage with the elastic pin, and the positioning liner at the lower end of the fixed post engages with the first opening, achieving axial height positioning and circumferential locking of the sleeve at the marking station; by the first positioning plate abutting against the second top surface, and the second positioning plate of the elastic fork abutting against the second inclined surface, anti-deviation constraint is achieved during the sleeve's removal from the transport vehicle. The return spring ensures that the second positioning plate is always subjected to an elastic force away from the first positioning plate, guaranteeing stable contact between the elastic fork and the second inclined surface, thereby ensuring the sleeve's positional accuracy before marking.

[0015] On the other hand, the present invention also provides a marking method for marking digital sleeves. The marking method is applied to the marking system in any of the above examples. The feeding end is also provided with a conveying mechanism. The marking method includes: acquiring the state information of the digital sleeve in a horizontal state; conveying the digital sleeve to a first adjusting mechanism; driving the first adjusting mechanism to adjust the digital sleeve from a horizontal state to a vertical state according to the state information; driving the conveying mechanism to transport the digital sleeve to a second adjusting mechanism; driving the second adjusting mechanism to adjust the angle of the digital sleeve around the axis to a first preset angle; driving the conveying mechanism to transport the digital sleeve to a transfer vehicle; conveying the digital sleeve to the discharge end via the transfer vehicle; driving the ejection mechanism on the marking positioning mechanism to eject the digital sleeve; adjusting the digital sleeve to a preset posture via the marking positioning mechanism; and marking the digital sleeve.

[0016] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: it can achieve the technical effects corresponding to any of the above examples, which will not be elaborated here.

[0017] In one embodiment of the present invention, driving the first adjustment mechanism to adjust the digital sleeve from a horizontal state to a vertical state according to state information includes: detecting whether the digital sleeve in the horizontal state is in a forward or reverse state by a first sensor; when the forward state is detected, driving the digital sleeve to rotate around a first rotation direction to adjust the digital sleeve from a horizontal state to a vertical state; when the reverse state is detected, driving the digital sleeve to rotate around a second rotation direction opposite to the first rotation direction to adjust the digital sleeve from a horizontal state to a vertical state.

[0018] In one embodiment of the present invention, the driving and transporting mechanism transports the digital sleeve to the second adjusting mechanism, and drives the second adjusting mechanism to adjust the angle of the digital sleeve around the axis to a first preset angle, including: driving the transporting mechanism to transport the digital sleeve onto the elastic positioning member, driving the digital sleeve to rotate around its axis through the elastic positioning member, determining whether the detection light of the second sensor is aligned with the positioning hole on the digital sleeve; if so, controlling the elastic positioning member to stop rotating, and determining that the angle of the digital sleeve at this time is the first preset angle.

[0019] In one embodiment of the present invention, the driving and handling mechanism transports the digital sleeve to the transfer vehicle, and the transfer vehicle transports the digital sleeve to the discharge end, including: controlling the telescopic column to rise and extend out of the mating hole on the positioning seat; driving the handling mechanism to disengage the digital sleeve from the elastic positioning member and then fitting it onto the telescopic column; controlling the telescopic column to descend and drive the digital sleeve into the positioning seat so that the positioning column first abuts against the first inclined surface; controlling the telescopic column to descend and disengage from the digital sleeve; using a suction cup to adhere to the second end of the digital sleeve, so that the digital sleeve rotates until the first top surface abuts against the positioning column; and controlling the suction cup to disengage from the digital sleeve.

[0020] In one embodiment of the present invention, the ejector mechanism on the driving marking and positioning mechanism ejects the digital sleeve. After the digital sleeve is adjusted to a preset posture by the marking and positioning mechanism, the digital sleeve is marked. This includes: driving the transmission vehicle to move to a preset position on the track near the discharge end, controlling the ejector mechanism to rise so that the fixed post extends into the first opening through the mating hole, controlling the elastic pin to descend and extend into the second opening to engage with the third opening of the fixed post, and the positioning liner engaging with the first opening so that the digital sleeve is adjusted to a first preset height; wherein, when the ejector mechanism rises, the elastic fork and the first positioning plate are controlled to move to the position corresponding to the second positioning notch so that when the elastic pin engages with the third opening, the first positioning plate abuts against the second top surface of the second positioning notch, and the elastic fork abuts against the second inclined surface of the second positioning notch so that the angle of the digital sleeve around its axis is adjusted to the first preset angle.

[0021] By adopting the technical solution of the present invention, the following technical effects can be achieved: (1) Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The first adjustment mechanism flips the horizontal sleeves with different postures into a vertical state, providing a stable reference for circumferential angle adjustment; the second adjustment mechanism adjusts the angle of the vertical sleeve around the axis to the first preset angle, realizing the initial circumferential positioning; the conveyor completes the high-speed conveying from the inlet end to the outlet end; the marking and positioning mechanism makes the sleeve smoothly leave the conveyor through the ejection mechanism and enter the marking station at the preset angle. Each mechanism has a clear division of labor and takes turns to work in sequence. Through multi-level posture correction, the sleeve is gradually adjusted to the target posture, which effectively solves the problem of inaccurate marking position caused by posture deviation on the production line. (2) The first sensor automatically detects whether the digital sleeve is in a forward or reverse state, and controls the first rotating arm to rotate in different directions based on the detection result, so that the sleeve can be uniformly adjusted to a vertical state regardless of its horizontal orientation when entering the system. This solution achieves forward and reverse adaptive flipping without manual intervention or additional reversing devices, improving the automation and compatibility of the feeding process; (3) By extending the fixed post into the first opening, the third opening at the end of the fixed post can engage with the elastic pin, and the positioning liner at the lower end of the fixed post engages with the first opening, thus achieving axial height positioning and circumferential locking of the sleeve at the marking station; by the first positioning plate abutting against the second top surface, and the second positioning plate of the elastic fork abutting against the second inclined surface, anti-deviation constraint is achieved during the sleeve's removal from the transport vehicle. The return spring ensures that the second positioning plate is always subjected to an elastic force away from the first positioning plate, guaranteeing stable contact between the elastic fork and the second inclined surface, thereby ensuring the positional accuracy of the sleeve before marking.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] See Figures 1 to 15The marking system 1 also includes: a first adjustment mechanism 200, a second adjustment mechanism 300, a transmission vehicle 400, and a marking positioning mechanism 500. A first adjusting mechanism 200 is located at the feed end 10. The first adjusting mechanism 200 is used to receive the digital sleeve 100 in a horizontal state and adjust the digital sleeve 100 from a horizontal state to a vertical state. A second adjusting mechanism 300 is located on one side of the first adjusting mechanism 200 and is used to adjust the angle of the digital sleeve 100 in a vertical state around its axis to a first preset angle. A conveyor 400 is located at one end of the track 30 near the feed end 10 and is used to convey the digital sleeve 100 to the discharge end 20. A marking and positioning mechanism 500 is located at the discharge end 20 and is provided with an ejection mechanism 510 for cooperating with the digital sleeve 100 to disengage the digital sleeve 100 from the conveyor 400. When the ejection mechanism 510 cooperates with the digital sleeve 100, the angle of the digital sleeve 100 around its axis is the first preset angle.

[0026] Preferably, the marking system 1 further includes a test platform 40 and a hopper, the hopper being used to transport the digital sleeve 100 to the test platform 40 after adjusting it to a horizontal state.

[0027] Preferably, the marking system 1 in this application further includes a transport mechanism 50, which is provided with a clamping member for holding the digital sleeve 100 and a transmission mechanism for driving the transport mechanism 50 to move, so as to transport the digital sleeve 100 from the first adjustment mechanism 200 to the second adjustment mechanism 300, or from the second adjustment mechanism 300 to the transfer vehicle 400.

[0028] The first adjustment mechanism 200 uniformly flips the horizontal sleeves with different postures into a vertical state, providing a stable reference for circumferential angle adjustment; the second adjustment mechanism 300 adjusts the angle of the vertical sleeve around the axis to a first preset angle, achieving preliminary circumferential positioning; the transfer carriage 400 completes high-speed conveying from the inlet end 10 to the outlet end 20; the marking and positioning mechanism 500, through the ejection mechanism 510, smoothly detaches the sleeve from the transfer carriage 400 and enters the marking station at a preset angle. Each mechanism has a clear division of labor and works in sequence, gradually adjusting the sleeve to the target posture through multi-stage posture correction, effectively solving the problem of inaccurate marking position caused by posture deviation on the production line.

[0029] Further, the digital sleeve 100 includes a first end 110 and a second end 120 disposed opposite to each other. The horizontal state includes a forward state and a reverse state. In the forward state, the first end 110 of the digital sleeve 100 faces a first direction; in the reverse state, the first end 110 of the digital sleeve 100 faces a second direction opposite to the first direction. The first adjustment mechanism 200 includes a first rotating arm 210, a first gripper 220, and a first sensor 230. The first rotating arm 210 is disposed on the test platform 40 of the feed end 10; the first gripper 220 is disposed on the first rotating arm 210. One end of the 0 is used to clamp the digital sleeve 100; the first sensor 230 is used to detect whether the digital sleeve 100 is in a forward or reverse state; wherein, when the first gripper 220 clamps the digital sleeve 100 in the forward state and drives the digital sleeve 100 to rotate around the first rotation direction, the digital sleeve 100 is adjusted to a vertical state; when the first gripper 220 clamps the digital sleeve 100 in the reverse state and drives the digital sleeve 100 to rotate around the second rotation direction opposite to the first rotation direction, the digital sleeve 100 is adjusted to a vertical state.

[0030] Specifically, in one embodiment of this application, when the first sensor 230 is working, the detection position of the acquisition end of the first sensor 230 is located directly in front of the digital sleeve 100 and between the digital sleeve 100 and the first gripper 220. Therefore, before controlling the first gripper 220 to grip the digital sleeve 100, it is necessary to control the first sensor 230 to move from the detection position to a position outside the first gripper 220 and the digital sleeve 100.

[0031] The first sensor 230 automatically detects whether the digital sleeve 100 is in a forward or reverse orientation, and controls the first rotating arm 210 to rotate in different directions based on the detection result. This ensures that the sleeve is uniformly adjusted to a vertical position regardless of its horizontal orientation when entering the system. This solution achieves adaptive forward and reverse rotation without manual intervention or additional reversing devices, improving the automation and compatibility of the feeding process.

[0032] Furthermore, the digital sleeve 100 has a positioning hole 130 on its body, and the first end 110 of the digital sleeve 100 has a first opening 111.

[0033] The second adjustment mechanism 300 includes a second rotating arm 310, an elastic positioning member 320, and a second sensor 330. The second rotating arm 310 is installed at the feed end 10 and located on one side of the platform 40 to be tested. The elastic positioning member 320 is installed at one end of the second rotating arm 310. The elastic positioning member 320 includes multiple claws 321 and a clamp 322 disposed on the outer periphery of the multiple claws 321. The outer diameter formed by the multiple claws 321 corresponds to the first opening 111. The clamp 322 is used to limit the opening range of the multiple claws 321. The second sensor 330 is installed at the feed end 10 and located on one side of the second adjustment mechanism 300. The second sensor 330 is used to locate the positioning hole 130. When the laser emitted by the second sensor 330 matches the positioning hole 130, the angle of the digital sleeve 100 around its axis is a first preset angle.

[0034] Preferably, the end of the elastic positioning member 320, which is composed of multiple claws 321, has a chamfer to make it easier for the elastic positioning member 320 to enter the first opening 111 of the digital sleeve 100.

[0035] Multiple claws 321 of the elastic positioning element 320 extend into the first opening 111 of the sleeve, and the opening range is limited by the clamp 322. This not only reliably supports the inner wall of the sleeve to transmit the rotational driving force, but also avoids damage to the inner wall of the sleeve due to excessive supporting force, thus achieving non-destructive clamping and rotational drive. At the same time, the positioning hole 130 on the sleeve body is detected by the second sensor 330. When the laser is aligned with the positioning hole 130, the rotation stops, realizing automatic coarse positioning of the sleeve around its axis angle, providing an accurate reference for subsequent fine positioning.

[0036] Furthermore, the feed end 10 is provided with a third rotating arm 60, and the third rotating arm 60 is located above the transfer vehicle 400. One end of the third rotating arm 60 is provided with a suction cup 61 that cooperates with the second end 120.

[0037] The transfer vehicle 400 includes a mounting base 410, a positioning seat 420, and a telescopic column 430. Mounting base 410 is mounted on track 30; positioning seat 420 is mounted on mounting base 410, positioning seat 420 is provided with positioning space 421 for cooperating with first end 110, positioning post 422 is provided on inner wall of positioning space 421, positioning seat 420 is also provided with mating hole 423 communicating with positioning space 421; telescopic post 430 is mounted on feed end 10, telescopic post 430 is provided corresponding to first opening 111, and telescopic post 430 cooperates with first opening 111 so that digital sleeve 100 is sleeved on telescopic post 430; wherein, first end 110 is provided with first positioning notch 112 cooperating with positioning post 422, first end 110 includes first top surface 1121 forming first positioning notch 112 and first inclined surface 1122, first inclined surface 1122 abuts against positioning post 422; when first top surface 1121 abuts against positioning post 422, the angle of digital sleeve 100 around its axis is a first preset angle.

[0038] Preferably, in one embodiment of this application, the transmission vehicle 400 is a magnetic levitation vehicle.

[0039] Specifically, after the positioning seat 420 receives the digital sleeve 100, the transfer vehicle 400 needs to move on the track 30 to below the suction cup 61 so that the suction cup 61 can be attracted to the second end 120 of the digital sleeve 100. The digital sleeve 100 is rotated by the third rotating arm 60, so that the first top surface 1121 abuts against the positioning post 422, and the angle of the digital sleeve 100 is adjusted to the first preset angle.

[0040] The circumferential positioning of the sleeve on the transfer vehicle 400 is achieved through the mechanical engagement between the positioning post 422 on the positioning seat 420 and the first positioning notch 112 on the first end 110 of the sleeve. The suction cup 61 of the third rotating arm 60 adsorbs the second end 120 of the sleeve and drives its rotation, causing the first top surface 1121 to finally abut against the positioning post 422, thus achieving precise angle locking of the sleeve on the transfer vehicle 400. The telescopic post 430 plays an auxiliary guiding and centering role during the positioning process, ensuring that the sleeve accurately enters the positioning space 421. This scheme further refines the coarse positioning, and the two-stage progressive approach significantly reduces angular errors.

[0041] Furthermore, the second end 120 is provided with a second opening 121, and the first opening 111 is connected to the second opening 121. The first end 110 is provided with a second positioning notch 113 that cooperates with the ejection mechanism 510. The first end 110 includes a second top surface 1131 and a second inclined surface 1132 forming the second positioning notch 113. An elastic pin 520 is provided above the marking positioning mechanism 500, which is positioned opposite the second opening 121.

[0042] The ejection mechanism 510 includes a mounting base 512, a fixing post 513, and an elastic fork 514. The mounting base 512 is mounted on the telescopic mechanism 511 of the discharge end 20 to drive the mounting base 512 to move up and down. The mounting base 512 is also provided with a first positioning plate 5121 that cooperates with the second top surface 1131. The fixing post 513 is mounted above the mounting base 512 and is positioned directly opposite the first opening 111. The end of the fixing post 513 is provided with a third opening 5131 that cooperates with the elastic pin 520. The lower end of the fixing post 513 is provided with a positioning liner 5132 that cooperates with the first opening 111. The elastic fork 514 is sleeved on the mounting base 512. The elastic fork 514 is provided with a second positioning plate 5141 that cooperates with the second inclined surface 1132. A return spring 515 is connected between the elastic fork 514 and the mounting base 512 so that the second positioning plate 5141 is subjected to an elastic force away from the first positioning plate 5121.

[0043] Specifically, the elastic fork 514 is provided with a hook 5142, one end of the return spring 515 is connected to the hook 5142, and the other end is fixedly connected to the mounting base 512.

[0044] By extending the fixing post 513 into the first opening 111, the third opening 5131 at the end of the fixing post 513 can engage with the elastic pin 520, and the positioning liner 5132 at the lower end of the fixing post 513 engages with the first opening 111, thus achieving axial height positioning and circumferential locking of the sleeve at the marking station. Through the contact between the first positioning plate 5121 and the second top surface 1131, and the contact between the second positioning plate 5141 of the elastic fork 514 and the second inclined surface 1132, anti-deviation constraint is achieved during the sleeve's removal from the transfer carriage 400. The return spring 515 ensures that the second positioning plate 5141 is always subjected to an elastic force away from the first positioning plate 5121, guaranteeing stable contact between the elastic fork 514 and the second inclined surface 1132, thereby ensuring the sleeve's positional accuracy before marking.

[0045] On the other hand, the present invention also provides a marking method for marking digital sleeves.
