Description

Technical Field

[0001] This invention relates to the fields of industrial automation and product labeling technology, and particularly to an automatic pad printing and labeling production line. Background Technology

[0002] In existing technologies, marking and labeling the surface of workpieces (such as trays) is a crucial downstream process in industrial production. Traditional production methods mainly employ a separate station operation mode, where the pad printing and labeling processes are completed sequentially on two separate machines or at two separate workstations. This separation results in significant waiting and idle time between processes, and prevents synchronous parallel operation, leading to long production cycles, low efficiency, and low equipment utilization. Furthermore, the lack of precise positioning during workpiece transfer between processes makes it difficult to guarantee product accuracy and consistency. Moreover, the independent equipment layout not only occupies more installation space but also increases equipment investment and maintenance costs, making it difficult to meet the demands of efficient automated production. Therefore, there is an urgent need for an automated production line that highly integrates pad printing and labeling functions, enables synchronous operation of each process, continuous flow between processes, and reliable and stable positioning accuracy, to solve the problems of low production efficiency and insufficient accuracy and stability in existing technologies. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides an automatic pad printing and labeling production line.

[0004] The technical solution of the present invention includes:

[0005] Machine tool;

[0006] The tray loading mechanism, clamping and transferring mechanism and tray unloading mechanism are sequentially arranged on the machine tool along the tray conveying direction; the tray conveying direction is defined as the X direction, and the direction perpendicular to the X direction in the horizontal plane is defined as the Y direction;

[0007] A printing mechanism and a labeling mechanism are sequentially arranged along the X direction on the opposite side of the clamping and transfer mechanism;

[0008] The clamping and transfer mechanism includes a transfer linear module with a driving direction along the X direction, and a first clamping device, a second clamping device, and a third clamping device fixed to the output end of the transfer linear module and arranged at intervals along the X direction.

[0009] The initial positions of the pad printing mechanism and the second clamping device are opposite each other along the Y direction, and the initial positions of the labeling mechanism and the third clamping device are opposite each other along the Y direction;

[0010] The corresponding working positions of the pad printing mechanism and the labeling mechanism are provided with a transfer mechanism, which receives and positions the material tray transferred by the clamping and transfer mechanism.

[0011] A further technical solution is as follows: the transfer mechanism includes a lifting drive component, a first transfer clamping component and a second transfer clamping component driven by the lifting drive component to perform lifting and lowering movements, wherein the first transfer clamping component and the second transfer clamping component correspond to the pad printing mechanism and the labeling mechanism, respectively.

[0012] A further technical solution is that both the first transfer clamping assembly and the second transfer clamping assembly include an X-axis clamping assembly for X-axis positioning of the material tray and a Y-axis clamping assembly for Y-axis positioning of the material tray.

[0013] A further technical solution is as follows: the pad printing mechanism includes a support frame, a pad printing Z-axis module fixed on the support frame, a lifting mounting frame driven to rise and fall by the pad printing Z-axis module, a template assembly fixed on the lifting mounting frame and extending above the pad printing station, and an ink coating assembly disposed on the lifting mounting frame for applying ink to the surface of the template assembly.

[0014] A further technical solution is that the labeling mechanism includes a label supply device; the label supply device includes a material supply module for supplying a material tape with a label, and a peeling component for peeling the label off the material tape backing paper.

[0015] A further technical solution is that the label supply device also includes a waste recycling module, which includes a waste recycling roller and a traction drive module for driving the waste recycling roller to rotate and recycle the backing paper of the strip after the label has been peeled off.

[0016] A further technical solution is as follows: the peeling assembly includes a peeling plate and a label tray disposed at the label dispensing end of the peeling plate. The label dispensing end of the peeling plate has a wedge-shaped structure and the upper surface is horizontal. There is a gap between the peeling plate and the label tray to allow the backing paper of the feed tape to pass through.

[0017] A further technical solution is that the labeling mechanism also includes a label picking and attaching device, which includes a vacuum adsorption component for picking up and attaching labels, and a three-axis drive module for driving the vacuum adsorption component to move along the Y, X and vertical directions respectively.

[0018] A further technical solution is that the material tray feeding mechanism includes a conveyor line and a rotary feeding assembly;

[0019] The conveyor line is used to transport the material tray to the predetermined loading position;

[0020] The rotary loading assembly includes a loading Z-axis module for Z-axis lifting, a loading X-axis module for X-axis movement, a rotary module for flipping the tray to a predetermined posture, and a rotary clamping jaw for holding the tray, all connected in sequence.

[0021] A further technical solution is that the structure of the material tray unloading mechanism is the same as that of the material tray loading mechanism, and the two are arranged symmetrically with the clamping and transfer mechanism as the center.

[0022] The beneficial technical effects of this invention are as follows: Through a single reciprocating stroke of the clamping and transfer mechanism, the simultaneous transfer of new material trays from the "loading station" to the "pad printing station," the transfer of already printed material trays from the "pad printing station" to the "labeling station," and the transfer of already labeled material trays from the "labeling station" to the "unloading station" can be completed at three stations simultaneously. Simultaneously, a transfer mechanism is provided at the pad printing and labeling stations to accurately receive and position the material trays transferred by the clamping and transfer mechanism. This allows the clamping and transfer mechanism to reset after releasing the material tray, preparing for the next reciprocating stroke. During this process, the four processes of loading, pad printing, labeling, and unloading operate synchronously and seamlessly, avoiding waiting time and idle time, shortening the production cycle, and significantly improving the overall production line efficiency and equipment utilization. In terms of precision, the transfer clamping mechanism provides bidirectional high-precision clamping and positioning for the pad printing and labeling processes, ensuring the accuracy of the printed pattern and the consistency of the label's position, significantly improving product yield. The entire production line achieves full automation from new material tray loading, posture flipping, process transfer, and finished product unloading, realizing continuous, efficient, high-precision, stable, and flexible automated production. The overall structure is compact and is particularly suitable for batch production of workpieces that undergo continuous surface printing and labeling. Attached Figure Description

[0041] In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0042] like Figure 1 As shown, the automatic pad printing and labeling production line of the present invention includes a machine base 100, a tray loading mechanism 300, a clamping and transferring mechanism 200, and a tray unloading mechanism 400 sequentially arranged on the machine base 100 along the tray conveying direction, and a pad printing mechanism 500 and a labeling mechanism 600 sequentially arranged on the opposite side of the clamping and transferring mechanism 200 along the tray conveying direction. The clamping and transferring mechanism 200 is used to clamp and transfer the tray along the conveying direction; the pad printing mechanism 500 is used to perform pad printing operations on the tray passing through the pad printing station; and the labeling mechanism 600 is used to perform labeling operations on the tray passing through the labeling station.

[0043] The conveying direction of the material tray is defined as the X-axis, the direction perpendicular to the X-axis in the plane is defined as the Y-axis, and the vertical direction is defined as the Z-axis. The working positions on the conveying path of the material tray corresponding to the material tray loading mechanism 300, pad printing mechanism 500, labeling mechanism 600 and material tray unloading mechanism 400 are defined as loading station, pad printing station, labeling station and unloading station, respectively.

[0044] like Figure 2 and Figure 3 The clamping and transfer mechanism 200 includes a transfer linear module 210 driven in the X direction, and a first clamping device 220, a second clamping device 230, and a third clamping device 240 fixed to the output end of the transfer linear module 210. The first clamping device 220, the second clamping device 230, and the third clamping device 240 are arranged at intervals along the X direction and are respectively fixed to the carrier plate 250 driven by the output end of the transfer linear module 210 via mounting brackets. The first clamping device 220, the second clamping device 230, and the third clamping device 240 have the same structure, each including a finger cylinder and a clamping jaw disposed at the output end of the cylinder, used to clamp and fix the material tray. The initial position of the second clamping device 230 is opposite to the pad printing mechanism 500 along the Y direction, and the initial position of the third clamping device 240 is opposite to the labeling mechanism 600 along the Y direction.

[0045] In one reciprocating stroke, the transfer linear module 210, with the first clamping device 220, the second clamping device 230, and the third clamping device 240 in their initial positions, respectively clamps the new material tray at the loading station, the material tray that has completed the pad printing at the pad printing station, and the material tray that has completed the labeling at the labeling station. Driven by the transfer linear module 210, the module moves one station stroke along the X direction to simultaneously transfer the new material tray, the material tray that has completed the pad printing, and the material tray that has completed the labeling to the pad printing station, the labeling station, and the unloading station, respectively, thereby realizing a continuous synchronous operation cycle of multiple stations.

[0046] like Figure 4 The pad printing station and the labeling station are also provided with a transfer mechanism 700, which is used to receive the material trays transferred by the clamping and transfer mechanism 200, and to position the material trays before pad printing and labeling at the corresponding pad printing station and labeling station.

[0047] The transfer mechanism 700 includes a lifting mechanism 710 and two sets of transfer clamping mechanisms 720. The lifting mechanism 710 includes a lifting fixing plate, a lifting drive 711 fixed below the lifting fixing plate, and a lifting platform 712 connected to the output end of the lifting drive 711 and driven by the lifting drive 711 to move up and down in the vertical direction; the two sets of transfer clamping mechanisms 720 are arranged on the lifting platform 712, corresponding to the pad printing station and the labeling station, respectively.

[0048] Preferably, a guide assembly 713 is provided between the lifting platform 712 and the lifting fixed plate to ensure that the lifting platform 712 rises and falls smoothly. The guide assembly 713 includes at least two guide rods fixed vertically below the lifting platform 712 and a guide sleeve fixed to the lifting fixed plate. The guide rods pass through the guide sleeve and form a sliding fit with the guide sleeve, thereby guiding and limiting the lifting movement of the lifting platform 712.

[0049] During the process of the clamping and transfer mechanism 200 transferring the trays to the pad printing station and the labeling station along the conveying direction, the lifting mechanism 710 is in a lowered state, so that the lifting platform 712 and the intermediate clamping mechanism 720 on it are in a low position, avoiding spatial interference with the moving clamping and transfer mechanism 200. When each tray reaches the corresponding station, the lifting mechanism 710 drives the lifting platform 712 to rise, and the intermediate clamping mechanism 720 contacts the tray and performs positioning; then, the clamping and transfer mechanism 200 releases the tray, simultaneously completing the loading, process part transfer and unloading.

[0050] Specifically, each set of transfer clamping mechanisms 720 includes an X-axis clamping assembly for X-axis positioning of the tray and a Y-axis clamping assembly for Y-axis positioning of the tray.

[0051] The X-direction pressing assembly includes a reference plate 721 fixed on the lifting platform 712, a first pressing plate 722 disposed opposite to the reference plate 721, and a first pressing drive member 723 that drives the first pressing plate 722 to move relative to the reference plate 721 in the X direction.

[0052] The Y-axis clamping assembly includes a second clamping drive 724 fixed on a reference plate 721, a second clamping plate 725 driven by the second clamping drive 724 to move along the Y direction, and a third clamping plate 726 disposed opposite to the second clamping plate 725. The third clamping plate 726 achieves relative displacement with the second clamping plate 725 through a third clamping drive 727 disposed on a support plate 250, ultimately achieving clamping and positioning of the material tray along the Y direction.

[0053] Furthermore, a first floating structure 728 is provided between the first pressing plate 722 and the output end of the first pressing drive 723; a second floating structure 729 is provided between the third pressing plate 726 and the output end of the third pressing drive 727. The first floating structure 728 and the second floating structure 729 respectively enable the first pressing plate 722 and the third pressing plate 726 to achieve flexible contact with the corresponding sides of the material tray during the pressing process.

[0054] In this embodiment, the first floating structure 728 includes a plurality of first compression springs arranged along the four corners of the first pressing plate 722. One end of each first compression spring is connected to the output end of the first pressing drive 723, and the other end is connected to the first pressing plate 722. The second floating structure 729 includes a plurality of second compression springs arranged along the four corners of the third pressing plate 726. One end of each second compression spring is connected to the output end of the third pressing drive 727, and the other end is connected to the third pressing plate 726.

[0055] like Figure 5 The pad printing mechanism 500 includes a support frame 510, a pad printing Z-axis module 520, a lifting mounting frame 530, a template assembly 540, and an inking assembly 550. The pad printing Z-axis module 520 is fixed to the support frame 510. The lifting mounting frame 530 is connected to the output end of the pad printing Z-axis module 520 and is driven by the pad printing Z-axis module 520 to move vertically. The template assembly 540 is fixed to the lifting mounting frame 530 and extends along the Y-direction above the pad printing station. The template assembly 540 has a pattern corresponding to the information to be printed.

[0056] The inking assembly 550 includes a pad printing Y-axis module 551, a fine-tuning drive 552, and an inking unit 553 driven by the fine-tuning drive 552. The pad printing Y-axis module 551 is fixed on the lifting mounting frame 530, and its output end drives the fine-tuning drive 552 to move along the Y direction. The inking unit 553 is connected to the output end of the fine-tuning drive 552, and is finely adjusted in the vertical direction under the drive of the fine-tuning drive 552 and applies ink to the surface of the template assembly 540.

[0057] During operation, the Z-axis module 520 drives the lifting mounting frame 530 to descend, bringing the template assembly 540 and inking assembly 550 down to the printing position on the material tray. Then, the fine-tuning drive 552 fine-tunes the inking unit 553, ensuring a preset inking distance between the inking unit 553 and the template assembly 540 in the vertical direction. Next, the Y-axis module 551 drives the inking unit 553 to reciprocate along the Y-axis, evenly coating the pattern surface of the template assembly 540 with ink. During the inking process, the lower surface of the template assembly 540 remains in contact with the surface of the material tray to be printed, thus transferring the pattern onto the tray and completing the printing operation.

[0058] like Figures 6 to 8 The labeling mechanism 600 includes a label supply device 610 that automatically outputs labels and a label picking and attaching device 620 for adsorbing the labels and attaching them to the material tray.

[0059] The label supply device 610 includes a mounting plate 611, and a feeding module and a waste recycling module disposed on one side of the mounting plate 611. The feeding module includes: a feeding roller 612 for winding a strip with labels; a plurality of first guide rollers 613 disposed along the label feeding path for guiding the strip; and a peeling assembly disposed at the end of the label feeding path for peeling the labels off the strip. The peeling assembly includes a peeling plate 614 and a label tray 615 disposed at the label dispensing end of the peeling plate 614. The label dispensing end of the peeling plate 614 has a wedge-shaped structure and its upper surface is horizontal. There is a gap between the peeling plate 614 and the label tray 615 for the backing paper of the feeding strip to pass through.

[0060] The waste recycling module includes: a waste recycling roller 616 for winding the backing paper of the strip after the label has been peeled off; a traction drive module 617 for driving the waste recycling roller 616 to rotate; a plurality of second guide rollers 618 arranged along the recycling path of the backing paper; and a tension roller arranged on the recycling path of the backing paper to keep the backing paper of the strip taut.

[0061] The feeding roller 612, each guide roller, tension roller and waste recycling roller 616 are all arranged in parallel on the mounting plate 611, and the roller shafts of the feeding roller 612 and the waste recycling roller 616 are rotatably mounted on the mounting plate 611 through bearings.

[0062] In this embodiment, the traction drive module 617 employs a servo motor, which is driven by the roller shaft of the waste recycling roller 616 via a transmission structure located on the other side of the mounting plate 611. The transmission structure includes a drive wheel fixed to the motor shaft of the servo motor, a driven wheel fixed to the roller shaft of the waste recycling roller 616, and a synchronous belt wound around the drive wheel and the driven wheel.

[0063] In use, the material strip is manually pulled from the feeding roller 612, passes around multiple first guide rollers 613, then around the gap between the peeling plate 614 and the labeling table from the upper surface of the peeling plate 614, and then back from the lower surface of the peeling plate 614. It then passes through multiple second guide rollers 618 and tension rollers, finally fixing the end of the material strip to the roller shaft of the waste recycling roller 616. When the servo motor is working, the waste recycling roller 616 rotates, driving the material strip to move along the label feeding path. When the material strip passes the label exit end of the peeling plate 614, the backing paper of the material strip passes over the label exit end of the peeling plate 614 and continues to move in the opposite direction. Meanwhile, the label continues to move horizontally along the upper surface of the peeling plate 614 to the label tray 615, thus automatically peeling the label off the backing paper of the material strip. Finally, the label picking and attaching device 620 adsorbs and attaches the peeled label to the tray.

[0064] The labeling and attaching device 620 includes a three-axis drive module and an attachment execution component. The three-axis drive module includes a labeling Y-axis module 621, a labeling X-axis module 622, and a labeling Z-axis module 623. The labeling Y-axis module 621 is fixed to the support frame 510, and its driving direction is along the Y direction. The labeling X-axis module 622 is installed at the output end of the labeling Y-axis module 621, and its driving direction is along the X direction. The labeling Z-axis module 623 is installed at the output end of the labeling X-axis module 622, and its driving direction is along the Z direction.

[0065] The labeling execution component is fixed to the output end of the labeling Z-axis module 623 via a horizontal mounting plate 625. It includes a vacuum adsorption component 624 for picking up labels from the label tray 615 and affixing them to designated positions on the tray. To ensure flexible contact during the picking process, a third floating structure 626 is provided between the vacuum adsorption component 624 and the horizontal mounting plate 625. This third floating mechanism includes a fastener penetrating the horizontal mounting plate 625 vertically and an elastic element fitted around the fastener. The lower end of the fastener is connected to the vacuum adsorption component 624, and both ends of the elastic element abut against the lower surface of the horizontal mounting plate 625 and the upper part of the vacuum adsorption component 624, respectively.

[0066] When the vacuum adsorption component 624 descends and contacts the label, it is displaced upward by the reaction force and compresses the elastic element. Under the elastic force of the elastic element, it floats slightly in the vertical direction to maintain flexible contact with the label and avoid rigid impact.

[0067] Furthermore, a vertical mounting plate extending vertically is provided below the horizontal mounting plate 625, and a linear slide rail 627 extending in the Z direction is provided on the vertical mounting plate. The vacuum adsorption component 624 is slidably connected to the linear slide rail 627 through a slider to maintain stable movement during its floating process.

[0068] like Figures 9 to 11 The material tray feeding mechanism 300 includes a conveyor line 310 and a rotary feeding assembly 320. The conveyor line 310 includes a conveyor support 311 and a first section of the conveyor line and a second section of the conveyor line arranged sequentially and running synchronously along the conveying direction. Both the first section of the conveyor line and the second section of the conveyor line include two sets of parallel synchronous belts, which are installed on the same horizontal plane.

[0069] The conveyor line 310 also includes a conveyor drive device 312 and a drive shaft 313 connected to the output end of the conveyor drive device 312. Two sets of first drive wheels 314 and two sets of second drive wheels 315 are fixedly mounted on the drive shaft 313. The two sets of first drive wheels 314 respectively mesh with two sets of synchronous belts of the first section of the conveyor line; the two sets of second drive wheels 315 respectively mesh with two sets of synchronous belts of the second section of the conveyor line.

[0070] At the beginning of the first section of the conveyor line, a first driven wheel 316 corresponding to each of its two sets of synchronous belts is provided; at the end of the second section of the conveyor line, a second driven wheel 317 corresponding to each of its two sets of synchronous belts is provided. Each of the first driven wheel 316 and the second driven wheel 317 is rotatably mounted on the conveyor support 311.

[0071] Driven by the conveying drive device 312, the drive shaft 313 synchronously drives all the synchronous belts of the first and second conveying lines to run, thereby realizing the continuous and synchronous conveying of the material tray between the first and second conveying lines.

[0072] In this embodiment, the two sets of synchronous belts of the first section of the conveyor line are spaced closer together, so that the two sets of synchronous belts are closer to the center area of ​​the material tray, providing more stable and reliable support for the material tray; while the wider spacing between the two sets of synchronous belts of the second section of the conveyor line provides installation space for the rotary feeding assembly 320.

[0073] The rotary feeding assembly 320 is located at the end of the second conveyor line, between its two sets of synchronous belts. The rotary feeding assembly 320 includes a feeding Z-axis module 321, a feeding X-axis module 322, a rotary module 323, and a rotary clamping jaw 324 for holding the material tray, connected in sequence. The feeding Z-axis module 321 is fixed to the machine base 100 and driven in the Z direction. The feeding X-axis module 322 is installed at the output end of the feeding Z-axis module 321 and driven in the X direction. The rotary module 323 is installed at the output end of the feeding X-axis module 322 and is used to drive the rotary clamping jaw 324 to rotate, thereby causing the material tray to flip to a preset posture.

[0074] In this embodiment, the output end of the feeding X-axis module 322 is driven to connect to a movable plate 325. The movable plate 325 has the rotating module 323 and a bearing seat 326 at its two ends along the Y direction, respectively. One side of the rotating clamping jaw 324 is driven to connect to the output end of the rotating module 323, and the other side is rotatably connected to the bearing seat 326 via a bearing. Preferably, the rotating module 323 is a rotary cylinder.

[0075] During operation, when the material tray is conveyed via the second conveyor line, the rotary clamping jaw 324 is in a lowered position to avoid obstruction. When the material tray reaches the predetermined loading position on the second conveyor line, the loading X-axis module 322 drives the rotary clamping jaw 324 to move below the material tray, and then the loading Z-axis module 321 drives it to rise and clamp the material tray. Afterwards, the loading X-axis module 322 transfers the material tray to the handover station with the clamping and transfer mechanism 200, and the rotary module 323 drives the material tray to flip to a preset posture. After the handover is completed, the loading Z-axis module 321 drives the rotary clamping jaw 324 to descend and reset, entering the next work cycle.

[0076] In this embodiment, the tray unloading mechanism 400 and the tray loading mechanism 300 have the same structure and are symmetrically arranged with the clamping and transferring mechanism 200 as the center. The tray unloading mechanism 400 receives the trays that have completed the pad printing and labeling from the clamping and transferring mechanism 200, flips them over, and transfers them to the corresponding conveyor line 310 below. Further details are omitted here.

[0077] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
