DETAILED DESCRIPTION

[0036] In order to further explain the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the utility model will be described in detail as follows in combination with the drawings and preferred embodiments.

[0037] Please refer to Figures 1 to 8 ​As shown, the variable function transfer device of the utility model is the core auxiliary equipment of the gilding machine, and the overall framework is composed of three core modules of supporting base body 1, material transfer mechanism 2 and limiting mechanism 3, and auxiliary modules such as linkage lifting mechanism 4. Among them, the supporting base body 1 is the basic bearing structure of the whole device, and the number is at least two, and each supporting base body 1 has a feeding end and a discharging end connected with the gilding machine. In the actual layout, the feeding end of the supporting base body 1 close to the gilding station 5 is accurately connected with the gilding station 5 of the gilding machine, and the discharging end of the supporting base body 1 away from the gilding station 5 is connected with the material collecting station 7 of the gilding machine, and the space between the adjacent two supporting base bodies 1 is reserved for setting auxiliary operation station 6, such as common film covering, multi-color gilding station, etc. A multi-process continuous operation production chain is constructed.

[0038] Specifically, the material transfer mechanism 2 undertakes the key task of transferring the workpiece between stations. The mechanical arm of the mechanism adopts a composite transmission structure, and the horizontal movement is realized by the first horizontal movement module 23. In the first horizontal movement module 23, the first motor 231 is used as a power source, the output shaft of which is connected with the driving gear in the gear and tooth belt assembly 232 through a shaft coupling, the driving gear rotates to drive the tooth belt to move, and the tooth belt is fixedly connected with the support arm 22 body, so that the support arm 22 body moves horizontally along the first linear guide assembly 233 arranged on the bearing base.

[0039] The vertical movement is realized by the first lifting module 24, and the second motor 241 drives the cam connecting rod 322 assembly 242, the rotation of the cam is converted into the vertical reciprocating movement of the support arm 22 body along the second linear guide assembly 243 through the connecting rod 322, and the second linear guide assembly 243 is connected between the support arm 22 body and the first linear guide assembly 233. The mechanical hand is equipped with at least two groups of interval vacuum suction assemblies 21, each group of vacuum suction assemblies 21 comprises two parallel interval suction disc groups 211 arranged on the power output end of the mechanical arm, and each suction disc group 211 is composed of a plurality of interval suction discs connected with the vacuum generator.

[0040] In actual work, the vacuum generator generates negative pressure, so that the suction disc can firmly adsorb the workpiece, and the mechanical arm moves in the horizontal and vertical directions to accurately transfer the workpiece treated by the gilding station 5 to the supporting base body 1 or between the supporting base bodies 1 and the auxiliary operation station 6.

[0041] Specifically, the limiting mechanism 3 is mainly used for fixing the material on the support base 1, and the first driving assembly 32 is composed of a first cylinder 321, a connecting rod 322 and a transmission rod 323. The first cylinder 321 is preferably a servo cylinder, one end of which is fixed on the rack 11, and the other end is hinged to the connecting rod 322. The extension direction of the connecting rod 322 is crosswise arranged with the driving direction of the transmission rod 323 and the first cylinder 321, and the transmission rod 323 is rotatably installed on the rack 11 through a bearing. A plurality of pressing plate strips 311 of the pressing plate assembly 31 are fixedly arranged on the transmission rod 323, and preferably, a flexible piece (not shown in the figure) is arranged on the pressing plate strip 311. When the first cylinder 321 is started, the connecting rod 322 is pushed to move, and the connecting rod 322 drives the transmission rod 323 to swing relative to the bearing plate 12, so that the pressing plate strip 311 drives the flexible piece to abut and press or release the material on the bearing plate 12.

[0042] Through the cooperation of the above-mentioned mechanisms, the device breaks through the single material transfer mode of the traditional gilding machine, can flexibly adjust the operation mode according to different production needs, and significantly improves the efficiency and flexibility of gilding processing. For example, in the traditional gilding machine, material transfer often needs manual intervention or simple mechanical devices, which is low in efficiency and easy to make errors, while the device realizes automatic and multi-mode material transfer, greatly improving the stability of production and product quality.

[0043] Specifically, the support base 1 is composed of a rack 11 and a bearing plate 12, the rack 11 is welded by high-strength steel material to form a stable frame structure. The bearing plate 12 is distributed with a plurality of through holes 121 arranged in a rectangular array, the diameter of the through holes 121 is 50mm, and the hole spacing is 35mm. In the material flow process, air can contact the material through the through holes 121 to play a good heat dissipation effect, avoiding the influence of heat generated by long-time processing on the quality of the material.

[0044] Specifically, the cooperation of the limiting mechanism 3 and the support base 1 realizes precise regulation and control through the linkage lifting mechanism 4. When the pressing plate strip 311 swings to press the material under the action of the first driving assembly 32, if the pressing plate strip 311 and the bearing surface of the bearing plate 12 are not parallel, the linkage plate 42 arranged on the connecting rod 322 or the transmission rod 323 will not abut the contact of the micro switch 41. The micro switch 41 is of normally closed type, which is electrically connected with the cooperative control unit, and the cooperative control unit can be a PLC controller. At this time, after receiving the signal of the micro switch 41, the cooperative control unit regulates and controls the work of the lifting driving unit 43.

[0045] In specific implementation, the lifting driving unit 43 comprises a lifting motor 431, a first speed reducer 432, a first shaft body 433, two first gear wheels 434 and two first gear racks 435. The output shaft of the lifting motor 431 is connected with the input shaft of the first speed reducer 432, the output shaft of the first speed reducer 432 is fixedly connected with the first shaft body 433, the two ends of the first shaft body 433 are respectively provided with a first gear wheel 434, and the two sides of the rack 11 are correspondingly provided with the first gear racks 435 meshing with the first gear wheels 434. When the lifting motor 431 is started, the first shaft body 433 is driven to rotate after the rotation speed is reduced and the torque is increased by the first speed reducer 432, and then the first gear wheels 434 are rolled on the first gear racks 435, so that the descending of the bearing plate 12 is realized, and the bearing surface is parallel to the pressing plate strip 311.

[0046] Specifically, in order to ensure the stability and accuracy of the movement of the bearing plate 12, the linkage lifting mechanism 4 is further provided with a first sliding rail module 44. The first sliding rail module 44 is composed of a first guide rail 441 arranged on the rack 11 and a first sliding block 442 slidingly arranged on the first guide rail 441, the bottom of the bearing plate 12 is welded with a first support frame 13, the first sliding block 442 is fixed on the first support frame 13 through bolts, the first shaft body 433 is rotatably arranged on the first support frame 13 through a bearing, and the extension direction of the first guide rail 441 is perpendicular to the direction of the material moving device.

[0047] This design ensures that the bearing plate 12 will not deviate during lifting, so that the pressing plate strip 311 can uniformly press the material, avoiding damage to the material or decline in processing quality due to uneven pressure. Compared with the traditional fixed pressing plate structure, the device can automatically adjust the parallelism of the pressing plate and the bearing surface, greatly improving the reliability of the material fixing and the stability of the processing.

[0048] Specifically, in actual production, when a plurality of support bases 1 are used in series, an efficient continuous operation process is formed. Taking two support bases 1 as an example, the mechanical arm of the former support base 1 first uses a group of suction cups of the vacuum suction assembly 21 to suck the material processed by the gilding station 5 through the negative pressure generated by the vacuum generator, and moves the material to the bearing plate 12 of the base. At this time, the first driving assembly 32 of the limiting mechanism 3 is started, the first cylinder 321 pushes the connecting rod 322, drives the transmission rod 323 to swing, and makes the pressing plate strip 311 tightly press and fix the material on the bearing plate 12. Then, the mechanical arm drives another group of suction cups to start the vacuum generator again to suck the fixed material on the bearing plate 12 and move it to the auxiliary operation station 6, such as the film coating station. After the operation is completed at the film coating station, the suction cups of the mechanical arm will suck the processed material again and move it to the bearing plate 12 of the latter support base 1 at the same time. The latter support base 1 repeats the above operation, and the mechanical arm moves the material from the bearing plate 12 to the next auxiliary operation station 6 or directly to the material collecting station 7.

[0049] During the whole transfer process, the double-suction disc group 211 of the vacuum suction assembly 21 works alternately, and through the precise control of the mechanical arm, seamless transfer of the workpiece is realized. The gear and belt assembly 232 of the mechanical arm and the cam connecting rod 322 assembly 242 composite transmission structure ensure the coordinated movement in the horizontal and vertical directions, so that the workpiece can accurately flow between stations.

[0050] For example, when multi-color hot stamping is performed, the workpiece can complete hot stamping of multiple colors between different support bases 1 and auxiliary work stations 6 in turn, without manual intervention, greatly improving production efficiency. Compared with the traditional single-station independent operation mode, the device realizes continuous automatic production of multiple processes, reduces the time loss and human error of the workpiece in the transfer process, can meet the production needs of different complex process combinations, and fully embodies the variable function advantage of the device.

[0051] Specifically, to further enhance the variable function of the device, a modular function expansion interface is designed on the support base 1. The specific structure is that a standardized clamping groove is arranged on the side of the rack 11, the shape of the clamping groove is a dovetail groove, and the size specification is uniform, facilitating the installation and removal of different function modules. At the same time, an electrical interface is arranged near the clamping groove, including a power supply interface and a data interface, for realizing the connection of the function module and the device control system. Taking the addition of the embossing function as an example, a special embossing module is designed, which includes an embossing roller, a driving motor and a control circuit.

[0052] The surface of the embossing roller is engraved with different pattern lines, and the driving motor is used to drive the embossing roller to rotate. When the embossing function needs to be added, the dovetail groove of the embossing module is aligned with the clamping groove on the rack 11 and inserted, and then the electrical interface is connected. Through parameter setting of the control system on the embossing module, the embossing function can be quickly added. This modular design enables the device to flexibly replace or add function modules such as UV curing and embossing according to different production needs, greatly expanding the application range of the device and improving its market competitiveness.

[0053] The variable function transfer device of the utility model realizes the efficient and stable transfer and fixation of the workpiece between multiple stations through the innovative design of the support base 1, the material transfer mechanism 2, the limiting mechanism 3 and other core components, as well as the coordinated cooperation of the linkage lifting mechanism 4, the modular function expansion structure and the visual identification linkage system and other auxiliary modules.

[0054] Specifically, the multiple quantity arrangement of the support base 1 and the modular interface design enable it to adapt to different production process requirements and realize multi-process continuous operation; the composite transmission structure of the material transfer mechanism 2 and the design of the double-suction disc group 211 ensure the accuracy and efficiency of the material transfer; the cooperation of the limiting mechanism 3 and the linkage lifting mechanism 4 ensures the reliability of the material fixing; and the modular functional expansion structure further enhances the variable functions and intelligent degree of the device.

[0055] Compared with the material transfer device of the traditional gilding machine, the overall technical solution has obvious advantages. It improves the automation degree of gilding processing, reduces manual intervention, and reduces production cost; realizes multi-mode operation, can meet the production needs of different complex processes, improves production efficiency and product quality; through the introduction of modular design and intelligent system, the adaptability and market competitiveness of the device are enhanced, providing an innovative and efficient solution for the gilding processing industry.

[0056] The gilding machine of the utility model comprises a variable function transfer device, an input station 8, a gilding station 5, a material receiving station 7, and a variable function transfer device connected between the gilding station 5 and the material receiving station 7. The variable function transfer device is arranged between the output end of the gilding station 5 and the input end of the material receiving station 7, and functions to realize the transfer operation of the material between the gilding station 5 and the material receiving station 7.

[0059] Specifically, the feeding station 8 is also equipped with a feeding mechanical arm 83, and a calibration workbench 84 and a temporary buffer table 85 working in cooperation with the feeding mechanical arm 83. The feeding mechanical arm 83 moves by its own driving mechanism (for example, in the form of a crank linkage), and uses a vacuum suction device to pick up the workpiece conveyed on the moving carrier plate 81, and then sends it to the calibration workbench 84 for preliminary position calibration. The calibration workbench 84 preliminarily calibrates the workpiece by means of roller contact and suction conveying belt, which receives the workpiece and transfers it to the temporary buffer table 85.

[0060] Specifically, the temporary buffer table 85 of the feeding station 8 is provided at the end with a stop assembly 851.

The driving control unit of the feeding station 8 exchanges electrical signals with the main control unit of the gilding machine. When the position sensor detects that the workpiece has reached the preset position of the temporary buffer table 85, the system main control unit instructs the stop motor 852 to drive the stop driving shaft 853 to rotate, driving the stop plate 854 to swing and extend to the working surface of the temporary buffer table 85, thereby achieving accurate stop positioning of the workpiece.

[0061] This stop positioning operation is beneficial for an adsorption and grabbing unit of the material transfer platform to accurately pick up the workpiece from the temporary buffer table 85 and send it to the gilding station 5, while another adsorption and grabbing unit of the material transfer platform can pick up the workpiece processed by the gilding station 5 in the previous step and send it to the support substrate, thereby realizing efficient parallel operation.

[0062] Specifically, the end of the temporary buffer table 85 is also provided with an adsorption fine adjustment assembly. When the stop plate 854 completes the stop positioning of the workpiece, the adsorption fine adjustment assembly performs secondary position fine adjustment on the workpiece, further improving the positioning accuracy of the workpiece before entering the gilding station 5.
