Description

Technical Field

[0001] The present invention relates to the technical field of hot stamping machines, and particularly discloses a hot stamping machine, a transfer platform with a switchable mode thereof, and a working method. Background Art

[0002] In the prior art, multi-station linkage hot stamping machines mostly adopt a setting where the upper and lower stations are directly docked. Often, the next action can only be executed after the workpiece is fixed or transferred, resulting in a high idle rate of the equipment and insufficient multi-process coordination ability. The linkage operation stations need to rely on manual or independent equipment intervention. At the same time, the rigid limit device is prone to uneven pressing due to the thickness error of the material, and the expansion of multiple stations is limited by the mechanical structure interference problem.

[0003] After retrieval, a patent for an invention with the publication number CN112918096B and the theme name of a multi-module hot stamping machine in the prior art includes a feeding mechanism, a feeding roller mechanism, a hot stamping mechanism with a number greater than or equal to 2 groups, a receiving mechanism, and a linkage lifting mechanism that drives multiple hot stamping mechanisms to perform hot stamping simultaneously. The feeding mechanism, the hot stamping mechanism, and the receiving mechanism are sequentially arranged on the frame. In this way, the multi-module hot stamping machine of the present invention can not only achieve overprint hot stamping of different colors but also achieve hot stamping of wide-width printing and multiple surfaces, with strong functionality and high working efficiency.

[0004] However, the above patent for an invention has the following technical defects: the multi-station coordination efficiency is insufficient. Although the linkage lifting mechanism realizes the synchronous lifting of multiple hot stamping mechanisms, each station needs to wait for the completion of the overall action cycle before performing the next process, resulting in a relatively high proportion of ineffective waiting time; the rigid positioning structure is prone to deviation correction lag due to the difference in material ductility during high-speed operation; the linkage lifting mechanism relies on mechanical pull rod transmission, and when adding stations, it is necessary to re-match the connection relationship between the traction rod and the transmission seat, resulting in the need to stop the machine for transformation during mode switching. Summary of the Invention

[0005] In order to overcome the disadvantages and deficiencies existing in the prior art, the purpose of the present invention is to provide a hot stamping machine, a transfer platform with a switchable mode thereof, and a working method to solve the technical problem of insufficient multi-process coordination ability existing in the prior art.

[0006] To achieve the above object, a transfer platform with a switchable mode for a hot stamping machine according to the present invention includes a loading table, a transfer manipulator reciprocally moving on the loading table, a limiting device cooperatively arranged with the transfer manipulator, and a control system electrically cooperating with the limiting device and the transfer manipulator; the loading table is located between the hot stamping device of an external hot stamping machine and the material receiving station, the limiting device includes a limiting member movably arranged relative to the loading table and a linkage control mechanism connected to the limiting member, the loading table is used for loading the workpieces processed by the hot stamping device, and the linkage control mechanism is used for driving the limiting member to switch the workpieces on the loading table between a fixed state and a movable state;

[0007] The control system is configured as follows: when the workpiece on the loading table is in a fixed state, it controls the transfer manipulator to return to the hot stamping device to perform the transfer action of the next workpiece; when the workpiece on the loading table is in a movable state, it controls the transfer manipulator to transfer the workpiece to a linkage operation station cooperating with the hot stamping device of the hot stamping machine.

[0008] Further, the limiting member can be a vacuum adsorption assembly. When the limiting member is a vacuum adsorption assembly, the linkage control mechanism is a vacuum generator.

[0009] Further, the number of the transfer manipulators is at least two. The two transfer manipulators are cooperatively arranged through the control system. The action execution area of one transfer manipulator covers the work material station, the hot stamping device and the loading table, and the action execution area of the other transfer manipulator covers the loading table, the linkage operation station and the material receiving station; one transfer manipulator is used for picking up the workpiece processed by the hot stamping device and transferring it to the loading table, and the other transfer manipulator is used for transferring the workpiece carried by the loading table to the linkage operation station and synchronously transferring the workpiece processed at the linkage operation station to the material receiving station. The workpiece that switches between the fixed state and the movable state is used to cooperate with the execution actions of the two transfer manipulators.

[0010] Further, the loading table includes a support frame, a support plate movably arranged relative to the support frame, and a lifting drive module for driving the support plate to reciprocate. The linkage control mechanism includes a linear drive unit, a connecting rod unit connected to the linear drive unit, and a transmission rod connected to the connecting rod unit. The limiting member is arranged on the transmission rod; the limiting member is a flexible pressing plate, and the linear drive unit drives the transmission rod to swing relative to the support plate through the connecting rod unit so that the flexible pressing plate presses against or disengages from the workpiece on the support plate.

[0011] Furthermore, after the linkage control mechanism drives the limiting part to approach the carrying platform to limit the material transferred by the first transfer robot on the carrying platform, the first transfer robot returns to the hot stamping device to pick up the processed material. At the same time, the linkage control mechanism drives the pressing part away from the carrying platform to release the material. Subsequently, the second robot moves to the carrying platform to pick up the released material under the linkage action of the first robot. The first robot returns to move the picked up material to the carrying platform and limits it through the pressing part. At the same time, the second robot transfers the picked up material to the linkage station and transfers the material processed by the linkage station to the material receiving station (which can be an independent material receiving station or use the transfer platform as a material receiving station).

[0012] By connecting multiple transfer platforms in series, the hot stamping mode of the hot stamping machine can be switched freely. For example, a laminating device can be set between two adjacent transfer platforms, and the laminating of the material after hot stamping can be realized in combination with the linkage of the transfer manipulator. In actual use, a hot stamping device with other pigments can also be set between the two transfer platforms to realize multi-color hot stamping without stopping the machine for waiting.

[0013] Furthermore, the linkage control mechanism also includes a position compensation unit, which includes a sensing element arranged on the support frame and used in conjunction with the pressing plate; the sensing element is electrically connected to the lifting drive module via the control system, and when the pressing plate does not press the material on the support plate, the sensing element detects a pressing plate no-pressing signal and sends the signal to the control system, and the control system regulates the lifting drive module to drive the support plate to move downward until the pressing plate presses the material on the support plate.

[0014] Furthermore, the lifting drive module includes a lifting motor arranged on a support plate, a reducer arranged at an output end of the lifting motor, a first output shaft arranged at an output end of the reducer, a first gear arranged at an output end of the first output shaft, and a first rack arranged on a support frame, the first gear is meshed with the first rack, and the induction element is electrically coordinated with the lifting motor via a control system.

[0015] Furthermore, there are multiple transfer platforms, and a linkage work station used in conjunction with the hot stamping device is set between two adjacent load-bearing platforms. The control system is used to control the transfer robot to make the material flow between the hot stamping device, the load-bearing platform and the linkage work station.

[0016] Furthermore, the transfer robot includes a connecting frame and two adsorption components arranged on both sides of the connecting frame. The transfer robot also includes a first driving module and a second driving module. The connecting frame is reciprocated along a first direction and is arranged on the supporting platform via the first driving module. The connecting frame is reciprocated along a second direction and is arranged on the supporting platform via the second driving module. The first direction and the second direction are arranged to cross each other.

[0017] Further, the first driving module includes a first driving motor, a gear toothed belt transmission assembly connected to the first driving motor, and a first guide rail module arranged in cooperation with the gear toothed belt transmission assembly; the second driving module includes a second driving motor, a cam connecting rod assembly connected to the second driving motor, a transmission plate connected to the output end of the cam connecting rod assembly, and a second guide rail module arranged in cooperation with the transmission plate;

[0018] The first guide rail module and the second guide rail module are arranged perpendicular to each other, the connecting frame is slidably arranged on the supporting platform via the first guide rail module, the connecting frame is connected to the toothed belt of the gear belt assembly, the transmission plate is slidably arranged relative to the first guide rail module via the second guide rail module, the connecting frame is slidably arranged on the transmission plate along the first direction and cooperates with the transmission plate in transmission along the second direction.

[0019] Furthermore, the transmission plate is provided with a first groove, the extension direction of the first groove is parallel to the first direction, and the connecting frame is provided with a rolling element rolling in the first groove. The connecting frame rolls with the transmission plate in the first direction with the help of the rolling element and the first groove, and the connecting frame cooperates with the transmission plate in the second direction with the help of the side wall of the first groove and the stopping contact of the rolling element in the second direction.

[0020] A working method of a transfer platform with switchable modes according to the above-mentioned hot stamping machine of the present invention comprises the following steps:

[0021] S1, start the control system to enable the first transfer robot located at the side of the hot stamping device to pick up the hot stamped material through the adsorption component; this step specifically includes: controlling the first drive module and the second drive module to work together to enable the first transfer robot to transfer the material to the support plate of the carrier along a composite trajectory of the first direction and the second direction;

[0022] S2, using the linkage control mechanism to drive the limiter so that the material on the carrier is in a fixed state (triggering the linear drive unit of the linkage control mechanism, driving the flexible pressing plate to press down and fix the material through the connecting rod unit, and at the same time the lifting drive module of the position compensation unit adjusts the height of the support plate until the triggering member triggers the sensing element), and the control system simultaneously controls the transfer robot to return to the hot stamping device to perform the next transfer action;

[0023] S3, control the first transfer robot to return to the hot stamping station, and at the same time control the second transfer robot on the receiving device (or linkage station) side to move to the loading platform preparation position;

[0024] S4, releasing the fixation of the flexible pressing plate on the material, and picking up the material through the adsorption component of the second transfer robot;

[0025] S5. Control the second transfer robot to transfer the workpiece along a composite trajectory opposite to the transfer direction to the linkage station, and at the same time control the first transfer robot to synchronously transfer the workpiece picked up at the hot stamping station to the carrier table; during this process, the first of the two adsorption components of the second transfer robot adsorbs the front end of the workpiece on the carrier table and transfers it to the linkage station, while the other adsorption component adsorbs the front end of the workpiece processed by the linkage station and transfers it to the material collection station (or another transfer platform).

[0026] S6. Repeat steps S1 - S5 to enable the workpieces processed by the hot stamping device to be continuously transferred or multi-station linked through the transfer of the carrier table. When the number of carrier tables is multiple, the workpieces are sequentially transferred to the target station through the transfer of adjacent carrier tables and transfer robots.

[0027] A hot stamping machine of the present invention includes a feeding station, a hot stamping device, a material collection station, and a transfer platform with a switchable mode of the above hot stamping machine. The transfer platform with a switchable mode of the hot stamping machine is arranged between the hot stamping device and the material collection station for transferring workpieces between the hot stamping device and the material collection station. When there are 2 transfer platforms, the other transfer platform is located after the linkage operation station and is used as the material collection station.

[0028] Furthermore, the feeding station includes a support frame, a moving plate reciprocally arranged on the support frame for carrying external workpieces, a feeding lifting mechanism arranged below the moving plate, and side support plates cross - arranged relative to the bearing surface of the moving plate. The moving plate and the side support plates are arranged opposite to each other in the vertical direction to form a storage space for storing external workpieces.

[0029] The feeding station further includes a feeding robot, a calibration platform, and a temporary storage workbench cooperatively arranged with the feeding robot. The feeding robot is driven by its driving mechanism (for example, a crank - connecting rod mechanism) to move, and uses a vacuum suction cup to pick up the workpiece transferred on the moving plate and transfer it to the calibration platform for preliminary calibration. The calibration platform preliminarily calibrates the workpiece by means of the roller contacting and adsorbing the conveyor belt. After receiving the workpiece, the adsorption conveyor belt transfers it to the temporary storage workbench.

[0030] Furthermore, the feeding station also includes a baffle assembly, which is located at the end of the temporary storage workbench. The baffle assembly includes a baffle motor, a baffle drive shaft connected to the baffle motor, a stop plate connected to the baffle drive shaft, and a position sensor installed on the support frame for detecting the position of the material. The driving device arranged at the feeding station is electrically coordinated with the control system. When the position sensor detects that the material enters the preset position of the temporary storage workbench, the control system regulates the baffle motor to drive the baffle drive shaft to rotate, and the stop plate is linked to swing and protrude from the working end surface of the temporary storage workbench to stop and position the material. The stopping and positioning operation facilitates an adsorption component of the transfer robot to accurately pick up the material on the temporary storage workbench to the hot stamping device. At the same time, another adsorption component of the transfer robot can pick up the material that has been hot stamped in the previous step of the hot stamping device to the support plate, thereby realizing efficient parallel operation.

[0031] Furthermore, the baffle assembly also includes a baffle adjustment unit, which includes a turbine that cooperates with the baffle drive shaft, a worm that meshes with the turbine, and an adjustment knob arranged at the end of the worm. In actual use, the adjustment knob can be manually adjusted by observing the position or tilt angle of the material on the temporary storage workbench, and the initial angle or swing range of the baffle drive shaft can be adjusted through the worm and the turbine, thereby adjusting the stop position or angle of the stop plate, further improving the applicability of the baffle assembly to different materials or precision requirements.

[0032] The transfer platform of a hot stamping machine with switchable modes of the present invention realizes the dynamic flow and multi-mode switching of the material after hot stamping through the coordinated cooperation of the carrier platform, the transfer manipulator, the limit device and the control system. In the initial state, the first transfer manipulator picks up the hot stamped material from the hot stamping device and transfers it to the support plate of the carrier platform along the composite track; the linkage control mechanism drives the flexible pressing plate to press the material through the linear drive unit, triggers the position compensation unit to adjust the height of the support plate to ensure the pressing effect, and at this time the control system controls the first manipulator to return to execute the next material pick-up.

[0033] When the material on the platform needs to be transferred, the limit device releases the material, and the second transfer robot starts synchronously to transfer the material to the linkage operation station or the material receiving station along the reverse composite trajectory. At the same time, the first robot transfers the new material to the platform. By connecting multiple transfer platforms in series, a laminating device or a multi-color hot stamping unit can be added between adjacent platforms. By using the alternating action of the robot and the precise control of the limit device, continuous operation and mode switching between different stations can be achieved, forming a composite process of hot stamping, laminating, and multi-color printing.

[0034] Beneficial effects of the present invention:

[0035] Through the fixed and movable state switching mechanism of the workpiece, the collaborative operation of the dual manipulators combined with the composite trajectory motion design, the present invention shortens the single operation cycle, while avoiding the time waste of the manipulator's no-load return journey, and significantly improves the efficiency and flexibility of the hot stamping operation.

[0036] The position compensation unit of the limit device ensures the pressing accuracy and stability of the workpiece through the closed-loop feedback of the sensing element and the lifting drive module, preventing offset or damage during the transfer process; the modular carrier table design supports the series expansion of multiple platforms, and the linkage operation stations such as film laminating and multi-color hot stamping can be freely configured according to requirements, breaking through the limitations of the single function of the traditional hot stamping machine; the composite transmission structure of the gear belt and the cam link in the drive module realizes the high-precision positioning and synchronous control of the manipulator.

[0037] Combined with the adaptive grasping ability of the vacuum adsorption component, it can be compatible with workpieces of different sizes and materials, greatly improving the versatility and production continuity of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] For the convenience of those skilled in the art to understand, the present invention will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the embodiments does not limit the present invention.

[0052] Please refer to Figures 1 to 11 As shown, a transfer platform with a switchable mode of a hot stamping machine of the present invention includes a carrying platform 1, a transfer manipulator 2 reciprocally moving on the carrying platform 1, a limiting device 3 cooperating with the transfer manipulator 2, and a control system electrically cooperating with the limiting device 3 and the transfer manipulator 2; the carrying platform 1 is located between the hot stamping device 5 of an external hot stamping machine and the material receiving station 7, the limiting device 3 includes a limiting member 31 movably arranged relative to the carrying platform 1 and a linkage control mechanism 32 connected to the limiting member 31, the carrying platform 1 is used for carrying the workpieces processed by the hot stamping device 5, and the linkage control mechanism 32 is used for driving the limiting member 31 to switch the workpieces on the carrying platform 1 between a fixed state and a movable state;

[0053] The control system is configured such that when the workpiece on the carrier table 1 is in a fixed state, the transfer manipulator 2 is adjusted to return to the hot stamping device 5 to perform the transfer operation of the next workpiece; when the workpiece on the carrier table 1 is in a movable state, the transfer manipulator 2 transfers the workpiece to the receiving station 7 or the linkage operation station 6 that cooperates with the hot stamping device 5 of the hot stamping machine.

[0054] In specific implementation, the carrier table 1 is located between the hot stamping device 5 and the receiving station 7, and is composed of a support frame 11, a lifting drive module 13, and a support plate 12 with adjustable height. The support plate 12 realizes vertical displacement through the lifting drive module 13 to match the pressing requirements of the limiting device 3. The limiting device 3 includes two implementation methods: one is a vacuum adsorption component 22, which controls the adsorption force through a vacuum generator to fix the workpiece; the other is a flexible pressing plate structure, in which a linear drive unit 33 (a cylinder in this embodiment) drives a transmission rod 35 to swing through a connecting rod, so that the flexible pressing plate presses down or releases the workpiece.

[0055] The control system adjusts the manipulator action in real time according to the state of the workpiece (fixed / movable): when the workpiece is fixed, the first transfer manipulator 2 returns to the hot stamping device 5 to pick up the hot-stamped workpiece and simultaneously pick up the workpiece at the feeding station 4; when the workpiece is released, the second transfer manipulator 2 transfers it to the linkage operation station 6, and simultaneously transfers the workpiece processed at the linkage operation station 6 in the previous step to the receiving station 7 (in this embodiment, the receiving station 7 is a transfer platform); at the same time, due to the control system adjusting the synchronous displacement of the two transfer manipulators 2, the first transfer manipulator 2 transfers the workpiece picked up from the feeding station 4 to the hot stamping device 5, and simultaneously transfers the workpiece processed at the hot stamping device 5 in the previous step to the carrier table 1; repeating this cycle and setting multiple transfer platforms can realize the multi-mode switching of the hot stamping machine, such as forming a composite process flow of hot stamping, laminating, and multi-color printing.

[0056] This solution realizes the synchronous progress of the hot stamping process and other processing technologies through the state switching of the carrier table 1 and the collaborative operation of multiple manipulators. After adopting the modular series design, a single production line can complete the full-process operation such as hot stamping - laminating - quality inspection - sorting, further shortening the production beat and significantly improving the performance compared with traditional segmented equipment.

[0057] Specifically, the linkage control mechanism 32 includes a linear drive unit 33, a connecting rod unit 34 connected to the linear drive unit 33, and a transmission rod 35 connected to the connecting rod unit 34. The limiting member 31 is arranged on the transmission rod 35; the limiting member 31 is a flexible pressing plate, and the linear drive unit 33 drives the transmission rod 35 to swing relative to the support plate 12 through the connecting rod unit 34, so that the flexible pressing plate presses or disengages from the workpiece on the support plate 12.

[0058] In this embodiment, the linear drive unit 33 is a servo cylinder, and its output end is rigidly connected to the transmission rod 35 through a hinge-type link unit 34. The middle of the transmission rod 35 is installed on the side wall of the support frame 11 of the carrier 1 through a rotary bearing, and a pressing plate is installed at the end. A detachable silica gel gasket is installed on the end face of the pressing plate close to the support plate 12 to prevent unnecessary damage to the material after hot stamping.

[0059] During specific operation, when the first transfer manipulator 2 transfers the hot-stamped material to the support plate 12, the control system sends an extension instruction to the servo cylinder, driving the link unit 34 to push the transmission rod 35 to rotate clockwise around the rotary bearing, so that the flexible pressing plate swings to the edge of the material at a uniform speed and presses it tightly. When the second transfer manipulator 2 needs to pick up the material, the servo cylinder retracts, driving the transmission rod 35 to rotate counterclockwise, and the flexible pressing plate is completely separated from the material.

[0060] The linkage control mechanism 32 adopts a rigid-flexible coupling pressing method, which not only ensures the positioning accuracy of the material but also avoids the surface indentation problem caused by traditional rigid jigs, especially suitable for easily damaged materials such as gold and silver cardboard. The closed-loop control cooperation between the servo electric push rod and the lifting drive module 13 further shortens the state switching response time and further speeds up compared with the traditional pneumatic mechanism. The elastic deformation characteristic of the flexible pressing plate can adaptively compensate for the thickness fluctuation of the material, improving the equipment compatibility. The coordinated operation of this mechanism and the double manipulators realizes the seamless connection between the continuous feeding of the hot stamping device 5 and the synchronous processing of the linkage operation station 6, further reducing the single-process beat time and further improving the overall production efficiency.

[0061] Specifically, the linkage control mechanism 32 further includes a position compensation unit. The position compensation unit includes a sensing element 36 arranged on the support frame 11 and used in cooperation with the pressing plate; the sensing element 36 is electrically connected to the lifting drive module 13 via the control system. When the pressing plate does not tightly press the material on the support plate 12, the sensing element 36 detects the signal that the pressing plate is not pressed and sends this signal to the control system, and the control system regulates the lifting drive module 13 to drive the support plate 12 to move down until the pressing plate tightly presses the material on the support plate 12.

[0062] The lifting drive module 13 includes a lifting motor 131 arranged on the support plate 12, a reducer 132 arranged at the output end of the lifting motor 131, a first output shaft 133 arranged at the output end of the reducer 132, a first gear 134 arranged at the output end of the first output shaft 133, and a first rack 135 arranged on the support frame 11. The first gear 134 meshes with the first rack 135, and the sensing element is electrically coordinated with the lifting motor 131 via the control system.

[0063] During the specific implementation process of the position compensation unit, two groups of photoelectric proximity sensors can be symmetrically installed on both sides of the top of the support frame 11 as the sensing element 36, and their detection ends are aligned with the preset pressing positions of the flexible pressing plates at the ends of the transmission rods 35. When the flexible pressing plates are driven by the transmission rods 35 to press down, if the thickness of the workpiece is insufficient or there is a position deviation, resulting in the pressing plates not reaching the preset height, the proximity sensors will detect that the reflected light intensity of the pressing plates is lower than the threshold value, and then send an uncompressed signal to the control system.

[0064] According to the received signal, the control system outputs a pulse signal to the lifting motor 131 of the lifting drive module 13. After driving the speed reducer 132 to reduce the speed, the first output shaft 133 drives the first gear 134 to mesh with the first rack 135 on the support frame 11 for transmission, so that the support plate 12 moves downward at a speed of 1 mm / s. This downward movement continues until the proximity sensors detect that the flexible pressing plates reach the preset pressing positions (the reflected light intensity meets the standard) and then automatically stops. At this time, the pressing force between the support plate 12 and the pressing plates reaches 1.8 - 2.2 N / cm 2 of the process requirement value. This compensation process forms a closed-loop control with the swinging action of the transmission rod 35 to ensure that the workpiece is always in a pressed state during the lifting process of the support plate 12.

[0065] The position compensation unit solves the problem of pressing failure caused by the thickness tolerance of the workpiece or the mechanical transmission gap through real-time detection and feedback adjustment, significantly improving the pressing qualification rate. The design of the gear-rack transmission mechanism combined with the precision speed reducer 132 realizes a height adjustment accuracy of millimeter level, reducing the backlash error compared with the traditional lead screw module. The linkage control of the photoelectric sensor and the lifting motor 131 controls the compensation response time within 0.2 seconds. Combining with the elastic deformation characteristics of the flexible pressing plates, it can automatically adapt to the workpiece thickness fluctuation within the range of 0.05 - 3 mm, further improving the equipment compatibility. This structure effectively avoids the production line downtime caused by manual intervention and adjustment.

[0066] Specifically, a plurality of transfer platforms are provided, and a linkage operation station 6 for cooperating with the hot stamping device 5 is arranged between two adjacent carrying platforms 1. The control system is used to control a plurality of transfer manipulators 2 to transfer the workpiece between the hot stamping device 5, the carrying platform 1, and the linkage operation station 6.

[0067] In actual implementation, for example, three loading platforms 1 are arranged at equal intervals along the conveying direction of the hot stamping device 5, and the distance between adjacent loading platforms 1 is set to 1.2 times the maximum arm span of the transfer manipulator 2. A linkage operation station 6 is arranged between the second and third loading platforms 1, and this station is integrated with a rotary powder removal mechanism and an infrared drying device. The first transfer manipulator 2 is responsible for transferring the workpieces processed by the hot stamping device 5 to the first loading platform 1; the second transfer manipulator 2 is responsible for transferring the workpieces after being pressed and positioned on the first loading platform 1 to the linkage operation station 6 for surface treatment; the third transfer manipulator 2 is responsible for transferring the workpieces that have completed the linkage operation to the third loading platform 1 to wait for subsequent processes.

[0068] The control system synchronously controls each transfer manipulator 2 and the lifting drive module 13 of the loading platform 1. Specifically, when the flexible pressing plate of the first loading platform 1 completes the pressing action, the PLC sends a material taking instruction to the second manipulator, and at the same time, the powder removal fan of the linkage operation station 6 is started; when the second manipulator executes the material taking action, the third loading platform 1 has been lowered in advance to the material receiving height through the lifting drive module 13 to form a continuous feeding rhythm. The movement trajectories of each manipulator are planned by the RRT algorithm to ensure interference-free collaborative operation with a positioning accuracy of ±0.5 mm.

[0069] The multi-station transfer system improves the utilization rate of the hot stamping device 5 through the parallel operation mode, and reduces the idle stroke waiting time compared with the single loading platform 1 structure. The coordinated control of the linkage operation station 6 and the loading platform 1 realizes the continuous production of hot stamping, powder removal, and drying processes, and further shortens the single-batch processing cycle compared with the traditional process. The modular design of the loading platform 1 structure supports the rapid replacement of support plates 12 of different specifications, making the equipment compatible with a variety of printing materials.

[0070] Specifically, the transfer manipulator 2 includes a connecting frame 21 and two adsorption components 22 arranged on both sides of the connecting frame 21. The transfer manipulator 2 further includes a first drive module 23 and a second drive module 24. The connecting frame 21 is reciprocally moved along a first direction on the loading platform 1 via the first drive module 23, and the connecting frame 21 is reciprocally moved along a second direction on the loading platform 1 via the second drive module 24, and the first direction and the second direction are arranged to intersect each other.

[0071] During actual use, the control system adjusts the actions of the manipulator in real time according to the state of the workpiece (fixed / movable): when the workpiece is fixed, one adsorption component 22 of the first transfer manipulator 2 returns to the hot stamping device 5 to pick up the hot-stamped workpiece, and the other adsorption component 22 picks up the workpiece at the feeding station 4; when the workpiece is released, one adsorption component 22 of the second transfer manipulator 2 transfers it to the linkage operation station 6, and the other adsorption component 22 synchronously transfers the workpiece processed at the linkage operation station 6 in the previous step to the material receiving station 7 (in this embodiment, the material receiving station 7 is a transfer platform); at the same time, since the control system adjusts the synchronous displacement of the two transfer manipulators 2, one adsorption component 22 of the first transfer manipulator 2 transfers the workpiece picked up from the feeding station 4 to the hot stamping device 5, and the other adsorption component 22 synchronously transfers the workpiece processed by the hot stamping device 5 in the previous step to the carrier table 1; by repeating this process and setting multiple transfer platforms, multi-mode switching of the hot stamping machine can be achieved, such as forming a composite process flow of hot stamping, laminating, and multi-color printing.

[0072] In this embodiment, the connection frame 21 of the transfer manipulator 2 is made of a lightweight alloy material to form a frame body, and adsorption components 22 are symmetrically arranged on both sides thereof. Each adsorption component 22 includes multiple groups of vacuum suction cups and a supporting pneumatic control system. The first driving module 23 includes a gear and belt transmission system driven by a first driving motor 231 (servo motor). The belt is arranged parallel to the long side direction of the carrier table 1, and the connection frame 21 is guided by a linear guide rail to move linearly in the first direction. Adjustable tensioning mechanisms are provided at both ends of the belt. (The gear and belt transmission system has higher positioning accuracy compared with the traditional chain transmission, and the tensioning mechanism can effectively eliminate the transmission gap)

[0073] The second driving module 24 uses a cam-link mechanism 242 driven by a second driving motor 241 (stepper motor). A disc cam with a specific eccentricity is installed on the camshaft, and the transmission plate 243 is driven by a connecting rod to move along a second guide rail perpendicular to the first direction. A two-way transmission cooperation is realized between the transmission plate 243 and the connection frame 21 through a rolling friction mechanism. Guide grooves with an extension direction parallel to the first direction are machined on its surface, and rolling elements 211 installed at the bottom of the connection frame 21 are embedded in the grooves to form a kinematic pair.

[0074] The rolling element 211 is made of bearing steel and is installed at the bottom of the frame through a slewing bearing assembly. The contact surface between the side wall of the groove and the rolling element 211 is hardened. When the first driving module 23 works, the rolling element 211 rolls freely along the groove to achieve displacement in the first direction; when the second driving module 24 drives, the rolling element 211 forms a pressure contact surface with the side wall of the groove, and the driving force in the second direction is transmitted through friction. This two-way transmission separation design avoids motion interference, and the hardening treatment improves the wear resistance of the contact surface.

[0075] Through the collaborative drive of the gear and belt assembly and the cam link assembly 242, combined with the rolling friction guiding mechanism, this solution realizes the composite motion control of the transfer manipulator 2 in the plane. When the two drive systems operate independently, they respectively complete single-axis precise positioning. When linked, complex path motion is achieved through the synthesis of motion trajectories. Compared with the traditional cross slide table structure, this design reduces the number of mechanical components, reduces space occupancy, and at the same time improves the transmission efficiency through the rolling friction pair. The overall structure has the characteristics of high rigidity and low wear, and is particularly suitable for high-frequency and high-precision material handling scenarios.

[0076] Specifically, in actual implementation, a vision recognition camera can be installed at the front end of the transfer manipulator 2. The camera is an industrial-grade high-definition camera, featuring high resolution and wide viewing angle. The camera is connected to the control system through a data cable, and an image recognition algorithm is built into the control system. When the adsorption assembly 22 approaches the workpiece to prepare for picking, the camera takes an image of the workpiece and transmits it to the control system. The control system analyzes and processes the image, and judges information such as the position, shape, and surface state of the workpiece through the image recognition algorithm. According to the recognition result, the control system automatically adjusts the motion trajectory of the robotic arm so that the suction cup of the vacuum adsorption assembly 22 can accurately align with the adsorption position of the workpiece.

[0077] At the same time, the control system can also adjust the suction force of the vacuum generator according to information such as the material and surface hardness of the workpiece to ensure firm adsorption without damaging the workpiece. For example, for workpieces with relatively fragile surfaces, the suction force is appropriately reduced; for workpieces with flat and hard textures, the suction force is increased. This vision recognition linkage system improves the adaptability of the device to different types of workpieces, especially suitable for the processing of workpieces with irregular shapes or special surface requirements, making the device more intelligent and automated, and further enhancing its creativity and technological advancement.

[0078] The transfer platform of the present invention is placed between the hot stamping device 5 and the material receiving station 7, and cooperates with the first and second transfer manipulators 2 and the linkage control mechanism 32 to realize the efficient transfer and circulation of workpieces.

[0079] The specific process is as follows: The first transfer manipulator 2 picks up the workpiece that has been hot stamped and transfers it along the composite trajectory to the carrier table 1. The carrier table 1 fixes the workpiece through the flexible pressing plate in the linkage control mechanism 32, and the manipulator returns to the hot stamping station to perform the next pick-up. Subsequently, the second transfer manipulator 2 takes over the operation, releases the pressing state and transfers the workpiece to the linkage operation station 6 or the material receiving station 7. At the same time, the workpiece completed in the previous step of the linkage operation is synchronously recycled to the material receiving station 7, and the first manipulator also synchronously sends a new workpiece to the hot stamping station. Multiple carrier tables 1 can be connected in series to form a multi-level transfer platform, realizing continuous and efficient circulation between hot stamping - linkage - material receiving. The switchability (fixed / movable) of the transfer platform state enables it to adapt to various production rhythms and multi-station composite process flows.

[0080] By setting a transfer platform with a switchable state, and combining the collaborative operation of dual manipulators, flexible limit and closed-loop control technologies, the present invention realizes the continuous transfer and dynamic connection of workpieces among processes such as hot stamping, linkage, and material collection. Its structure is modular, the operation cycle is short, and the adaptability is strong. It can effectively improve the multi-mode integration ability of hot stamping equipment, significantly shorten the production cycle, enhance the flexibility and automation degree of the production line, and is especially suitable for the efficient batch processing of high-precision and vulnerable materials. The overall manufacturing efficiency and product yield are significantly better than the prior art.

[0081] A working method of a transfer platform with a switchable mode for a hot stamping machine according to the present invention specifically comprises the following steps:

[0082] Dual-axis composite transfer stage: When the first transfer manipulator 2 picks up the hot stamping workpiece through two adsorption components 22, the gear and belt mechanism of the first drive module 23 and the cam link mechanism of the second drive module 24 receive synchronous instructions from the control system, and drive the connection frame 21 to move along the composite trajectory in the first direction (X-axis) and the second direction (Y-axis), so that the workpiece is accurately positioned at the central area of the support plate 12 of the carrier table 1. During this process, the rolling element 211 rolls along the composite path in the groove of the transmission plate 243, avoiding trajectory deviation caused by sliding friction.

[0083] Linkage positioning and synchronous reset stage: After the workpiece is positioned, the linear drive unit 33 of the linkage control mechanism 32 pushes the limiting member 31 downward, and the flexible pressing plate uniformly presses and fixes the edge of the workpiece through elastic deformation; simultaneously, when the flexible pressing plate does not tightly press the edge of the workpiece, the lifting drive module 13 of the position compensation unit finely adjusts the height of the support plate 12 until the trigger contacts the sensing element 36 and feeds back the in-place signal. At this time, the control system immediately controls the first transfer manipulator 2 to return to the hot stamping station along the original path, and at the same time, the second transfer manipulator 2 moves to the standby position of the carrier table 1.

[0084] Dual-manipulator alternating operation stage: When the adsorption component 22 of the second transfer manipulator 2 picks up the fixed workpiece, its drive module transfers the workpiece to the linkage station along the reverse composite trajectory, and at the same time, the other adsorption component 22 of this manipulator synchronously grabs the semi-finished product processed at the linkage station to the material collection position. During this process, the two adsorption components 22 of the first transfer manipulator 2 respectively suck the workpiece at the feeding station 4 to the hot stamping device 5, and suck the workpiece processed by the hot stamping device 5 to the support plate 12 of the carrier table 1. The independent air circuit control system of the two adsorption components 22 switches the adsorption state according to the process requirements to avoid air flow interference.

[0085] Multi-carrier 1 extended operation stage: When the system is configured with multiple carriers 1, each carrier 1 receives materials in a preset order, and the adjacent carriers 1 are transferred by the transfer robot 2 to achieve secondary positioning transfer of materials. The control system automatically allocates the robot movement path according to the carrier 1 number to ensure that there is no conflict in the path when multiple materials are transferred continuously.

[0086] A hot stamping machine of the present invention comprises a feeding station 4, a hot stamping device 5, a material receiving station 7 and a transfer platform with switchable modes of the hot stamping machine. The transfer platform with switchable modes of the hot stamping machine is arranged between the hot stamping device 5 and the material receiving station 7, and is used to transfer materials between the hot stamping device 5 and the material receiving station 7.

[0087] Specifically, the feeding station 4 includes a support frame 40, a movable plate 41 reciprocatingly arranged on the support frame 40 for carrying external materials, a feeding lifting mechanism arranged below the movable plate 41, and a side support plate 42 arranged to cross the bearing surface of the movable plate 41. The movable plate 41 and the side support plate 42 are arranged opposite to each other in a vertical direction to form a storage space for storing external materials.

[0088] The feeding station 4 also includes a feeding manipulator 43, a calibration platform 44 and a temporary storage workbench 45 which are arranged in cooperation with the feeding manipulator 43. The feeding manipulator 43 is driven to move by its driving mechanism (for example, a crank connecting rod mechanism), and uses a vacuum adsorption plate to pick up the material transferred on the moving plate 41, and transfers it to the calibration platform 44 for preliminary calibration. The calibration platform 44 performs preliminary calibration on the material by means of roller contact and adsorption of the conveyor belt, and transfers the material to the temporary storage workbench 45 after receiving the material on the adsorption conveyor belt.

[0089] Specifically, the feeding station 4 further includes a baffle assembly 46, which is located at the end of the temporary storage workbench 45. The baffle assembly 46 includes a baffle motor 461, a baffle drive shaft 462 connected to the baffle motor 461, a stop plate 463 connected to the baffle drive shaft 462, and a position sensor installed on the support frame 40 for detecting the position of the material. The driving device provided in the feeding station 4 is electrically coordinated with the control system. When the position sensor detects that the material enters the preset position of the temporary storage workbench 45, the control system controls the baffle motor 461 to drive the baffle drive shaft 462 to rotate, and the stop plate 463 is linked to swing and protrude from the working end surface of the temporary storage workbench 45 to stop and position the material.

[0090] The stopping and positioning operation facilitates an adsorption component 22 of the transfer robot 2 to accurately pick up the material on the temporary storage workbench 45 to the hot stamping device 5. At the same time, another adsorption component 22 of the transfer robot can pick up the material after the hot stamping process of the hot stamping device 5 in the previous step to the support plate 12, realizing efficient parallel operation.

[0091] In this embodiment, an adsorption-type distance adjustment component is provided at the end of the temporary storage workbench 45. After the stop plate 463 stops and positions the material, the adsorption-type distance adjustment component performs a secondary calibration on the material to further improve the positioning accuracy of the material before entering the hot stamping device 5.

[0092] Specifically, the baffle assembly 46 further includes a baffle adjustment unit 464, which includes a turbine 465 that cooperates with the baffle drive shaft 462, a worm 466 that meshes with the turbine 465, and an adjustment knob 467 disposed at the end of the worm. In actual use, the adjustment knob 467 can be manually adjusted by observing the position or tilt angle of the material on the temporary storage workbench 45, and the initial angle or swing range of the baffle drive shaft 462 can be adjusted through the worm 466 and the turbine 465, thereby adjusting the stop position or angle of the stop plate 463, further improving the applicability of the baffle assembly 46 to different materials or precision requirements.

[0093] This method constructs a closed-loop transfer system through dual manipulator collaborative control, real-time feedback of linkage positioning mechanism and path planning of multiple carriers. Its core lies in:

[0094] The compound trajectory motion and synchronous reset mechanism of the dual manipulators eliminates the waiting idleness of the traditional single manipulator; the linkage positioning of flexible pressing and position compensation ensures the accuracy of material fixation; the dynamic path allocation of the multi-carrier 1 realizes the flexible expansion of the production line.

[0095] Compared with the single-station direct delivery mode of traditional hot stamping machines, this solution significantly improves the overall efficiency of the equipment and further reduces the drive energy consumption due to the optimization of the robot path.
