Description

Technical Field

[0001] This utility model relates to the field of inkjet mechanism technology, specifically to an inkjet mechanism. Background Technology

[0002] Inkjet printing mechanisms are used to automate inkjet printing operations on product surfaces.

[0003] Existing equipment mostly employs mechanical transmission structures, such as gear meshing or belts driving the clamp rotation. After long-term operation, these are prone to wear, loosening, or increased transmission clearance, leading to uneven product rotation speed, inaccurate start-stop positioning, and resulting in inkjet pattern misalignment, edge trailing, or localized over-spraying or under-spraying. Furthermore, clamping relies on manual adjustment or fixed positioning, resulting in poor repeatability and weak adaptability to model changes. Moreover, most systems lack online recognition and dynamic compensation mechanisms for the actual position and posture of the workpiece, failing to correct turntable indexing errors or clamping misalignments. This leads to low inkjet consistency, significantly impacting production efficiency and product quality stability.

[0004] Therefore, there is an urgent need for an inkjet mechanism to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide an inkjet mechanism to solve the problem of inkjet printing in products.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An inkjet printing mechanism, comprising:

[0008] A turntable, wherein an installation station is provided on the turntable, and a clamping assembly is installed at each installation station;

[0009] The processing station, including a loading station, an identification station, a driving station and an inkjet station, is located around the turntable. The turntable rotates to drive each of the fixture assemblies through the processing station.

[0010] The clamping assembly is used to clamp the product to be inkjet printed, and includes a rotating part and a main magnetic block. The rotating part is used to rotate and position the product to be inkjet printed, and the main magnetic block is connected to the rotating part and rotates synchronously with the rotating part.

[0011] At the loading station, a robotic arm installs the product to be inkjet into the fixture assembly;

[0012] A rotating source and a contour camera are set at the recognition station. The rotating source is retractably mounted at the recognition station, and the contour camera is reciprocally mounted at the recognition station. When the turntable drives each of the clamping components to pass through the recognition station, the rotating source moves along the clamping components to drive the inkjet product to rotate, and the contour camera takes pictures along the length direction of the inkjet product.

[0013] The magnetic block is rotatably mounted on the drive station. When the turntable drives the clamping assembly past the drive station, the magnetic block is magnetically coupled with the main magnetic block to transmit rotational driving force, driving the rotating part to rotate the inkjet product.

[0014] The printhead, installed at the inkjet station, is used to perform surface inkjet printing on the rotating product to be inkjet printed.

[0015] As a preferred embodiment of an inkjet mechanism, the rotating part includes a base and a idling assembly, the idling assembly being idling mounted on the base;

[0016] The idling assembly includes a first rotating shaft and a second rotating shaft oscillatingly mounted at both ends of the base. A gap is left between the first rotating shaft and the second rotating shaft for mounting the inkjet product. The first rotating shaft and the second rotating shaft are respectively mounted with a first clamping block and a second clamping block facing each other to cooperate with the inkjet product. The first clamping block is fixedly mounted on the first rotating shaft, and the second clamping block is rotatably mounted on the second rotating shaft. The main magnetic block is mounted at the end of the first rotating shaft. The second rotating shaft is connected to the base through an elastic element. The second rotating shaft can extend and retract along the direction of the gap to clamp or release the inkjet product.

[0017] As a preferred embodiment of an inkjet mechanism, the clamping assembly further includes a clamping component to clamp the first rotating shaft mounted on the base, thereby keeping the workpiece relatively stationary with respect to the base.

[0018] The drive station is equipped with an unlocking component, which is set along the direction of reciprocating to the clamping component to unlock the clamping component; the mating magnetic block is rotatably mounted on the unlocking component, and the mating magnetic block faces the main magnetic block;

[0019] When the turntable drives the clamping assembly past the drive station, the unlocking component moves along the direction of the clamping component to unlock the clamping component.

[0020] As a preferred embodiment of an inkjet mechanism, the clamping assembly includes a clamping plate and a spring. The clamping plate is movably disposed on the base along the radial direction of the first rotating shaft and abuts against the outer peripheral surface of the first rotating shaft. The spring is disposed between the clamping plate and the base and is used to apply an elastic force toward the first rotating shaft to the clamping plate, so that the clamping plate clamps the first rotating shaft under normal conditions.

[0021] The unlocking component is composed of a push rod. When the push rod moves towards the clamping component, it acts on the clamping plate, pushing the clamping plate to move outward against the elastic force, thereby releasing the clamping of the idling component and restoring the idling component to its rotational freedom.

[0022] As a preferred embodiment of an inkjet printing mechanism, the inkjet printing station includes:

[0023] Support base;

[0024] A lifting drive source is installed on the support base;

[0025] A motion plate is disposed at the output end of the lifting drive source along the lifting direction of the support base, and the lifting drive source drives the motion plate to move up and down along the lifting direction of the support base.

[0026] A tilting drive source is rotatably disposed at the output end of the lifting drive source relative to the support base;

[0027] A bracket is rotatably mounted on the motion plate relative to the support base. The bracket is rotatably connected to the output end of the tilt drive source. The tilt drive source drives the bracket to rotate about the connecting axis between the motion plate and the support base.

[0028] The nozzle is mounted on the bracket, which is movable back and forth relative to the support base via a front and rear drive source.

[0029] As a preferred embodiment of an inkjet mechanism, the tilt drive source and the support base are connected by a connecting plate, one end of the connecting plate is fixedly connected to the moving plate, and the other end of the connecting plate is rotatably connected to the tilt drive source.

[0030] As a preferred embodiment of an inkjet mechanism, the output end of the tilt drive source moves relative to the lifting direction of the support base. The output end of the tilt drive source is connected to the bracket via an auxiliary rotary joint. The auxiliary rotary joint is disposed on the support base, and its two ends are rotatably connected to the output end of the tilt drive source and the bracket, respectively.

[0031] As a preferred embodiment of an inkjet mechanism, the auxiliary rotary joint includes a fixed rod, a connecting rod, and a connecting block. The fixed rod is mounted on the connecting plate, and one end of the fixed rod is rotatably connected to the output end of the tilting drive source. The connecting block is disposed on the bracket, and both ends of the connecting rod are rotatably connected to the fixed rod and the connecting block, respectively.

[0032] As a preferred embodiment of an inkjet mechanism, the surface of the printhead is provided with an encoding camera, and the clamping assembly is provided with a marking code. When the turntable rotates to drive each of the clamping assemblies past the inkjet station, the encoding camera takes a picture to record the position of the marking code in order to adjust the position of the printhead.

[0033] As a preferred embodiment of an inkjet printing mechanism, it also includes a feed belt for conveying the product to be inkjet printed to the loading station.

[0034] The beneficial effects of this utility model are as follows: by setting a main magnetic block in the fixture assembly and configuring a rotatable mating magnetic block at the drive station, when the turntable drives the fixture assembly to the drive station, the main magnetic block and the mating magnetic block automatically align and magnetically couple, transmitting rotational torque in a non-contact manner, thereby driving the rotating part to rotate the product. Since magnetic coupling transmission is used instead of mechanical contact transmission, wear and clamping deviation are avoided, and rotational synchronization and positioning repeatability are improved.

[0035] Meanwhile, a retractable rotating source and a movable contour camera are set up at the recognition station. The rotating source pushes and drives the product to rotate, and the camera scans along the axis to achieve high-precision contour recognition.

[0036] Combined with the continuous operation of the rotary multi-station, the product can be accurately identified and its posture corrected before inkjet printing, ultimately achieving stable rotation and uniform inkjet printing for complex curved surface products. Attached Figure Description

[0067] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0068] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0069] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0070] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0071] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0072] In one embodiment of this utility model, such as Figure 1-8 As shown, an inkjet printing mechanism is provided, including: a turntable 1, a clamping assembly 2, a loading station 501, an identification station 502, a driving station 503, and an inkjet printing station 504. A turntable 1 is provided with installation stations, each equipped with a clamping assembly 2. Processing stations, including a loading station 501, an identification station 502, a drive station 503, and an inkjet station 504, are located circumferentially around the turntable 1. The turntable 1 rotates to drive each clamping assembly 2 through the processing stations. The clamping assembly 2, used to hold the product to be inkjet printed, includes a rotating part 201 and a main magnetic block 202. The rotating part 201 rotates and positions the product, and the main magnetic block 202 is connected to the rotating part 201 and rotates synchronously with it. The loading station 501 uses a robotic arm to install the product into the clamping assembly 2. A rotating source 10 and a contour camera 11 are located at the identification station 502. A rotating source 10 is retractably mounted on the recognition station 502, and a contour camera 11 is reciprocally mounted on the recognition station 502. When the turntable 1 drives each clamping assembly 2 past the recognition station 502, the rotating source 10 moves along the clamping assembly 2 to drive the inkjet product to rotate, and the contour camera 11 takes pictures along the length direction of the inkjet product. The magnetic block 12 is rotatably mounted on the drive station 503. When the turntable 1 drives the clamping assembly 2 past the drive station 503, the magnetic block 12 is magnetically coupled with the main magnetic block 202 to transmit the rotational driving force, driving the rotating part 201 to drive the inkjet product to rotate. The printhead 19 is mounted on the inkjet station 504 and is used to perform surface inkjet operation on the inkjet product that is rotating.

[0073] The inkjet mechanism provided by this utility model sets a main magnetic block 202 in the clamping assembly 2 and a rotatable mating magnetic block 12 in the drive station 503. When the turntable 1 drives the clamping assembly 2 to the drive station 503, the main magnetic block 202 and the mating magnetic block 12 automatically align and magnetically couple, transmitting rotational torque in a non-contact manner, thereby driving the rotating part 201 to rotate the product. Since magnetic coupling transmission is used instead of mechanical contact transmission, wear and clamping deviation are avoided, and rotational synchronization and positioning repeatability are improved.

[0074] Meanwhile, a retractable rotating source 10 and a movable contour camera 11 are set at the recognition station 502. The rotating source 10 pushes and drives the product to rotate, and the camera scans along the axis to achieve high-precision contour recognition.

[0075] Combined with the continuous operation of the rotary table in multiple stations, the product can be accurately identified and its posture corrected before inkjet printing, ultimately achieving stable rotation and uniform inkjet printing for complex curved surface products.

[0076] like Figure 4 As shown, the rotating part 201 further includes a base 211 and an idler assembly 212, which is mounted on the base 211 in an idler manner.

[0077] The idling component 212 includes a first rotating shaft 213 and a second rotating shaft 214, which are idling mounted at both ends of the base 211. A gap is left between the first rotating shaft 213 and the second rotating shaft 214 for mounting the inkjet product. The first rotating shaft 213 and the second rotating shaft 214 are respectively mounted with a first clamping block 215 and a second clamping block 216 facing each other to cooperate with the inkjet product. The first clamping block 215 is fixedly mounted on the first rotating shaft 213, and the second clamping block 216 is rotatably mounted on the second rotating shaft 214. A main magnetic block is mounted at the end of the first rotating shaft 213. The second rotating shaft 214 is connected to the base 211 through an elastic element 6. The elastic element 6 is pre-tightened to make the clamping force for the inkjet product uniform and controllable. The second rotating shaft 214 can extend and retract along the direction of the gap to clamp or release the inkjet product.

[0078] In this embodiment, the second rotating shaft 214 can be driven by the cylinder to overcome the pre-tightening force of the elastic element 6 and move along the gap direction, thereby increasing the size of the gap between the first clamping block 215 and the second clamping block 216, which facilitates the placement of the inkjet product; then the cylinder resets, and under the restoring force of the elastic element 6, the second rotating shaft 214 drives the second clamping block 216 to automatically retract, thereby achieving reliable clamping of the product and effectively improving the repeatability and efficiency of the inkjet process.

[0079] In this embodiment, the loading station 501 can be symmetrically arranged on the circumferential position of the turntable 1 as the unloading station.

[0080] Preferably, the clamping assembly 2 further includes a clamping assembly 8 to clamp the first rotating shaft 213 mounted on the base 211, thereby keeping the workpiece and the base 211 relatively stationary.

[0081] Furthermore, such as Figure 4 As shown, the drive station 503 is equipped with an unlocking component 13, which can be set along the direction of the reciprocating clamping component 8 via a slide table to unlock the clamping component 8; the magnetic block 12 is rotatably mounted on the unlocking component 13, and the magnetic block faces the main magnetic block.

[0082] When the turntable 1 drives the clamping assembly 2 past the drive station 503, the unlocking assembly 13 moves along the direction of the clamping assembly 8 to unlock the clamping assembly 8.

[0083] In this embodiment, the magnetic block 12 can be rotated by installing a motor to drive it.

[0084] By rotatably mounting the mating magnetic block onto the unlocking assembly 13, when the unlocking assembly 13 moves towards the clamping assembly 8, it causes the mating magnetic block to synchronously approach the main magnetic block, thereby achieving magnetic pre-coupling between the two magnetic blocks and establishing a reliable connection for subsequent transmission. After or simultaneously with the establishment of magnetic coupling, the unlocking assembly 13 acts on the clamping assembly 8, releasing the clamp on the idle component 212 and allowing it to enter a rotatable state. Subsequently, the mating magnetic block rotates, causing the main magnetic block and the workpiece to rotate synchronously. During the retraction of the unlocking assembly 13, the magnetic attraction remains, which can suppress the workpiece from unexpected rotation due to inertia or external force until the clamping assembly 8 fully resets and clamps the idle component 212. It achieves coordinated control of "forward pre-engagement, unlocking transmission, and return rotation suppression": During the forward movement, magnetic pre-coupling establishes a reliable torque transmission path in advance to ensure no loss of rotation when starting; unlocking occurs after or simultaneously with the completion of magnetic coupling, avoiding idling due to the clamping component 8 not being released; during the return movement, the maintenance of magnetic force can suppress unexpected rotation of the workpiece, ensuring that the workpiece is in its initial position when the clamping is reset, effectively improving the reliability of the transmission, the controllability of the action, and the repeatability of the workpiece positioning, thereby increasing production speed.

[0085] Furthermore, such as Figure 5 As shown, the clamping assembly 8 includes a clamping plate 801 and a spring 802. The clamping plate 801 is movably disposed on the base 211 along the radial direction of the first rotating shaft 213 and abuts against the outer peripheral surface of the first rotating shaft 213. The spring 802 is disposed between the clamping plate 801 and the base 211 and is used to apply an elastic force toward the first rotating shaft 213 to the clamping plate 801 so that the clamping plate 801 clamps the first rotating shaft 213 under normal conditions.

[0086] like Figure 4 As shown, the unlocking component 13 is composed of a push rod 131. When the push rod 131 moves in the direction of the clamping component 8, it acts on the clamping plate 801, pushing the clamping plate 801 to move outward against the elastic force, thereby releasing the clamping of the idling component 212 and restoring the rotational freedom of the idling component 212.

[0087] Under the elastic force of spring 802, clamping plate 801 normally presses against the outer periphery of the first rotating shaft 213, thereby locking the idle component 212 and keeping the product stationary and stable in loading, identification and other workstations. By configuring push rod 131 type unlocking component 13 at drive station 503, when clamping component 2 reaches drive station 503, push rod 131 moves forward and pushes clamping plate 801 to overcome the force of spring 802 and move radially outward, releasing the clamping of the first rotating shaft 213 and allowing the idle component 212 to regain its rotational freedom. At this time, it is coupled with magnetic block 12 and main magnetic block 202 to realize power transmission.

[0088] Preferred, such as Figure 6-8 As shown, inkjet station 504 includes: support base 14, lifting drive source 15, motion plate 16, tilting drive source 17, bracket 18 and printhead 19.

[0089] A lifting drive source 15 is installed on a support base 14; a moving plate 16 is disposed at the output end of the lifting drive source 15 along the lifting direction of the support base 14, and the lifting drive source 15 drives the moving plate 16 to move up and down along the lifting direction of the support base 14; a tilting drive source 17 is rotatably disposed at the output end of the lifting drive source 15 relative to the support base 14; a bracket 18 is rotatably disposed on the moving plate 16 relative to the support base 14, and the bracket 18 is rotatably connected to the output end of the tilting drive source 17, and the tilting drive source 17 drives the bracket 18 to rotate around the connecting axis between the moving plate 16 and the support base 14; and a nozzle 19 is mounted on the bracket 18 and can move back and forth relative to the support base 14 via a front and rear drive source 20.

[0090] The height of the printhead 19 is adjusted by moving the motion plate 16 and the bracket 18 along the lifting direction via the lifting drive source 15; the tilt drive source 17 drives the bracket 18 to rotate around the connecting axis between the motion plate 16 and the support base 14 to tilt the printhead 19; the front and rear drive source 20 directly drives the printhead 19 to move back and forth relative to the bracket 18 to adjust the spraying distance. The coordinated action of the drive sources forms an all-round adjustment structure for height, angle, and front and rear position, which improves the adaptability of inkjet to products and avoids problems such as blurry ink, uneven ink layer, or missed spraying.

[0091] Furthermore, the tilt drive source 17 and the support base 14 are connected by a connecting plate 21, so that the rotation output end of the tilt drive source 17 and the bracket 18 form a stable torque transmission path. One end of the connecting plate 21 is fixedly connected to the motion plate 16, and the other end of the connecting plate 21 is rotatably connected to the tilt drive source 17.

[0092] Furthermore, the output end of the tilt drive source 17 moves relative to the lifting direction of the support base 14. The output end of the tilt drive source 17 is connected to the bracket 18 through an auxiliary rotary joint 22. The auxiliary rotary joint 22 is disposed on the support base 14, and its two ends are rotatably connected to the output end of the tilt drive source 17 and the bracket 18, respectively. This structure eliminates motion interference between the lifting and tilting movements through the auxiliary rotary joint 22, ensuring smooth rotation and precise angle of the bracket 18.

[0093] Furthermore, such as Figure 8As shown, the auxiliary rotary joint 22 includes a fixed rod 221, a connecting rod 222, and a connecting block 223. The fixed rod 221 is mounted on the connecting plate 21, and one end of the fixed rod 221 is rotatably connected to the output end of the tilting drive source 17. The connecting block 223 is disposed on the bracket 18, and both ends of the connecting rod 222 are rotatably connected to the fixed rod 221 and the connecting block 223, respectively. The bracket 18 experiences balanced force during tilting and lifting movements, effectively eliminating swaying and improving the angle adjustment accuracy of the bracket 18.

[0094] In this embodiment, the movement can be guided by a linear guide module to ensure that the movement proceeds in the expected direction. Alternatively, motors can be installed as drive sources to drive the nozzles 19 to move along a preset path.

[0095] Preferred, such as Figure 3 As shown, the surface of the printhead 19 is provided with an encoding camera 23, and the clamping assembly 2 is provided with a marking code 24. When the turntable 1 rotates to drive each clamping assembly 2 to pass through the inkjet station 504, the encoding camera 23 takes a picture and records the position of the marking code 24 in order to adjust the position of the printhead 19.

[0096] An encoding camera 23 is installed on the printhead 19, and a marking code 24 is set on the fixture assembly 2. When the turntable 1 drives each fixture assembly 2 past the inkjet station 504, the encoding camera 23 captures the position information of the marking code 24 in real time, obtaining the actual coordinate deviation of each fixture assembly 2 relative to the printhead 19. This ensures the accurate relative position of the printhead 19 and the product, avoiding misalignment, ghosting, or offset of the inkjet pattern.

[0097] Furthermore, such as Figure 1 As shown, it also includes a feeding belt 3, which is used to transport the inkjet products to the loading station 501, so that the products can be automatically fed according to the rhythm, thereby achieving synchronous connection with the turntable 1 station.

[0098] In this embodiment, as Figure 1 As shown, a protective cover 4 can be installed around the equipment to isolate the inkjet area from the external environment, thereby preventing ink mist diffusion and reducing pollution and safety risks.

[0099] The working process in this embodiment is as follows:

[0100] Feeding and loading: The feeding belt 3 transports the product to the loading station 501. The turntable 1 stops, and the cylinder drives the second rotating shaft 214 to move outward, widening the clamping block spacing. After the robot arm places the product, the cylinder resets, and the elastic element 6 (such as spring 802) drives the second rotating shaft 214 to retract and clamp the product. The clamping plate 801 in the clamping assembly 8 locks the first rotating shaft 213 in the idle assembly 212, so that the workpiece to be inkjet can remain stationary relative to the base 211, completing the loading.

[0101] Contour recognition: Turntable 1 with clamp assembly 2 stops at recognition station 502, rotating source 10 extends and docks with first rotating shaft 213, driving the product to rotate at a constant speed; contour camera 11 moves along the length of the product, scans 360° and transmits data to the system. After the system plans the inkjet path, rotating source 10 is reset, and turntable 1 sends clamp to drive station 503.

[0102] Drive unlocking: Drive station 503 push rod 131 forward, push clamp plate 801 releases clamping on first rotating shaft 213, idle component 212 resumes rotation; cooperate with magnetic block 12 as push rod 131 approaches, magnetically coupled with main magnetic block 202, establish torque transmission path.

[0103] Inkjet operation: The magnetic block 12 drives the product to rotate at a constant speed. The coding camera 23 takes pictures of the marking code 24. Through the lifting, tilting and front and rear drive sources 20 of the inkjet station 504, the height, angle and distance of the printhead 19 are adjusted. The printhead 19 sprays ink onto the rotating product according to the path to ensure uniform coating.

[0104] Reset and unloading: After inkjet printing, the magnetic block 12 stops rotating, the push rod 131 retracts, and the clamp 801 locks the idle component 212 (magnetic attraction maintains anti-inertia rotation); the clamp cylinder drives the second rotating shaft 214 to release the material, completing the cycle, and the turntable 1 continues to rotate to realize automated production.

[0105] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
