Description

Technical Field

[0001] The utility model relates to the technical field of pad printing equipment, in particular to a double-station four-treadle high-speed intelligent pad printing equipment. Background Art

[0002] Pad printing equipment is a special printing device that uses a copper or steel gravure and a pad printing head made of silicone rubber to accurately transfer patterns or text from the printing plate to the substrate (such as the surface of an irregularly shaped object) through transfer printing.

[0003] Existing pad printing equipment is generally a double-station turntable or a double-station dual-treadmill. However, the accuracy of the turntable pad printing machine cannot reach ±0.03mm, and the double-station dual-treadmill pad printing machine requires the pad printing mechanism to wait for each product loading and unloading and visual correction process, resulting in low processing efficiency.

[0027] In the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0028] The present invention provides a dual-station four-treadmill high-speed intelligent pad printing device, comprising a workbench 100, a conveyor line 112 provided on the outer surface of the workbench 100, a loading and unloading mechanism 200 provided between the conveyor line 112 and the workbench 100, the conveyor line 112 being used to convey a material storage tray, and the loading and unloading mechanism 200 being used to load the material in the material storage tray and return the printed material to the material storage tray. A first bracket 101 is mounted on the upper surface of the workbench 100, two CCD modules 102 are mounted on the lower surface of the first bracket 101, and two double-sided reverse moving modules 103 are mounted on the upper surface of the workbench 100, both sides of the double-sided reverse moving modules 103 are mounted with cantilevered treadmills 105 via a lifting device 104, and the double-sided reverse moving modules 103 can drive the two cantilevered treadmills 105 to move relative to each other. Since the two cantilevered treadmills 105 can be adjusted in height by the lifting device 104 to achieve a height difference, the purpose of position exchange can be achieved. A UVW platform module 106 is mounted on the upper surface of the bilateral counter-moving module 103, corresponding to the CCD module 102. A lifting mechanism 104 drives the cantilevered treadmill 105 to a designated height. At this point, the CCD module 102 above the material and the UVW platform module 106 below the material perform CCD calibration. A second bracket 107 is mounted on the upper surface of the workbench 100. Two pads 109 are mounted on this bracket via a first translation and lifting module 108. An ink cup module 110 and a cleaning module 111 are mounted on either side of the upper surface of the workbench 100. The first translation and lifting module 108 drives the pads 109 into contact with the ink pattern on the ink cup module 110, which then contacts the material, completing the printing process. Both sides of the upper surface of the workbench 100 are provided with inclined lifting mechanisms 300, which are used to provide support for the bottom of the cantilever treadmill 105. A lifting block 600 and two lifting adsorption members 601 are installed at the bottom of the conveyor line 112. The lifting block 600 and the lifting adsorption members 601 are both driven by cylinders. When the conveyor line 112 conveys the storage tray, the lifting block 600 pushes upward to block the storage tray, thereby ensuring the accuracy of the storage tray position. Then, the two lifting adsorption members 601 push upward and lift the two pieces of material on the storage tray and adsorb them. When the first pair of mechanical claws 202 grab the material, the first pair of mechanical claws 202 first moves to one side of the material, then moves to the bottom of one of the materials for adsorption, and then moves to the other side of the material, and then moves to the bottom of the other material for adsorption, thereby achieving the purpose of simultaneously adsorbing two pieces of material.

[0029] See also Figure 3 and Figure 4The loading and unloading mechanism 200 includes a second translation and lifting module 201 installed on the conveyor line 112, a first pair of mechanical claws 202 are installed at the movable end of the second translation and lifting module 201, a material transfer platform 203 is installed on the upper surface of the workbench 100, and a correction device 204 is provided at the bottom of the material transfer platform 203. A second pair of mechanical claws 206 are installed on the upper surface of the workbench 100 through a third translation and lifting module 205. When loading, the first pair of mechanical claws 202 are driven by the second translation and lifting module 201 to grab two pieces of material and place the two pieces of material on the material transfer platform 203. The position of the material is corrected by the correction device 204 to ensure the accuracy of the position. During the placement process, the first pair of mechanical claws 206 are driven by the third translation and lifting module 205 to grab two pieces of material and place the two pieces of material on the material transfer platform 203. The position of the material is corrected by the correction device 204 to ensure the accuracy of the position. The double mechanical claws 202 first places one of the materials on one of the suction cup groups on the material transfer platform 203 and adsorbs it. Then the first pair of mechanical claws 202 moves horizontally, driving the material to move to another suction cup group on the material transfer platform 203 and adsorb it. Then the first pair of mechanical claws 202 moves horizontally to the middle position of the material transfer platform 203. At this time, the length of the first pair of mechanical claws 202 is less than the distance between the two pieces of material, so the first pair of mechanical claws 202 can be lifted upward, and then the third translation and lifting module 205 drives the second pair of mechanical claws 206 to adsorb the two pieces of material and place them on the two cantilever runners 105 on both sides, thereby completing the loading. Similarly, the printed materials can also be collected.

[0030] See also Figure 1 and Figure 2 The inclined lifting mechanism 300 includes a base plate 301 mounted on the upper surface of the workbench 100, a servo motor 302 is mounted on the upper surface of the base plate 301, the output shaft of the servo motor 302 is connected to a screw rod 304 through a transmission belt 303, a first wedge block 305 is mounted on the outer surface of the screw rod 304, and the first wedge block 305 is slidably connected to the upper surface of the base plate 301, a vertical guide rail 306 is mounted on the upper surface of the base plate 301, a second wedge block 307 is slidably mounted on the outer surface of the vertical guide rail 306, and the second wedge block 307 is slidably mounted on the outer surface of the second wedge block 30 7 is adapted to the first wedge block 305. The servo motor 302 drives the screw rod 304 to rotate, driving the first wedge block 305 to move horizontally along its length. Because the second wedge block 307 is limited by the vertical guide rail 306, it can move upward under the pressure of the first wedge block 305 and abut against the lower surface of the cantilever platform 105 to provide support. This prevents the downward pressure generated by the rubber head 109 during printing from causing deformation of the cantilever platform 105, thereby ensuring the service life and accuracy of the equipment. Furthermore, by converting rotational motion into linear motion, the extrusion generated by this linear motion drives the second wedge block 307 upward, thus providing a highly precise travel distance for the second wedge block 307 and ensuring effective support for the cantilever platform 105.

[0031] See also Figure 1 and Figure 2 Two groups of hollow tubes 400 are installed on the lower surface of the second bracket 107. Each group of hollow tubes 400 includes two symmetrically arranged hollow tubes 400. A hot air device is provided inside the hollow tube 400. A plurality of nozzles 401 are installed on the opposite surfaces of the two hollow tubes 400. A lifting suction cup (not shown in the figure) is also provided in the cantilever treadmill 105. The lifting suction cup is driven by a cylinder and is used to adsorb and fix the material. When the material is printed, the lifting suction cup drives the material to rise so that the material is between the nozzles 401 on both sides. Then the hot air device in the hollow tube 400 generates hot air and blows it to the material through the nozzle 401, so that the printed pattern on the material can be quickly dried. After drying is completed, the lifting suction cup descends, and the two cantilever treadmills 105 on the bilateral reverse moving module 103 exchange positions. Two fourth translation and lifting modules 500 are provided on the lower surface of the second bracket 107, and the movable end of the fourth translation and lifting module 500 is provided with a sampling mechanical claw 501. Two sampling platforms 502 are installed on the upper surface of the workbench 100, and the two sampling platforms 502 correspond to the two sampling mechanical claws 501 respectively. When it is necessary to conduct sampling inspection on the printed materials during the production process, the fourth translation and lifting module 500 can be used to drive the sampling mechanical claw 501 to move and adsorb the material on the jacking suction cup, and then the material is transferred to the sampling inspection platform 502 through the fourth translation and lifting module 500, and the staff can take out the material on the sampling inspection platform 502 for inspection.

[0032] The specific workflow and working principle of this device are as follows.

[0033] When in use, the storage tray is transported by the conveyor line 112. After arriving at the specified position, the lifting block 600 is pushed out upward to block the storage tray. The two materials are grabbed at the same time by the loading and unloading mechanism 200 and placed in the two cantilever treadmills 105 respectively. The cantilever treadmill 105 is driven to rise to the specified height by the lifting device 104. At this time, the CCD module 102 above the material and the UVW platform module 106 below the material perform CCD calibration on it, and then the two cantilever treadmills 105 are driven to move relative to each other by the bilateral reverse moving module 103. Since there is a height difference between the two cantilever treadmills 105 at this time, the purpose of position exchange can be achieved. After the position exchange is completed, the cantilever treadmill 105 is driven by the lifting device 104 to descend to the specified height, and then the first translation lift The lowering module 108 drives the rubber head 109 to move to the top of the oil cup module 110, and then makes the rubber head 109 descend and contact with the ink with the pattern on the oil cup module 110. Then the first translation and lifting module 108 drives the rubber head 109 to move to the top of the cantilever treadmill 105, and makes the rubber head 109 descend and contact with the material in the cantilever treadmill 105, thereby completing the printing. Finally, the bilateral reverse moving module 103 exchanges the position, and the printed material is placed on the material storage tray through the loading and unloading mechanism 200. Due to the alternating up and down operation of the double-station four-treadmill, the loading and unloading time and CCD correction time can be saved, and the production efficiency can be improved while ensuring the accuracy of the original linear treadmill equipment, and the labor cost can be saved. The number of similar equipment layouts can be reduced while ensuring the production line capacity. After the pad 109 finishes printing ink, the first translation and lifting module 108 drives the pad 109 to move directly above the ink cup module 110. The cleaning module 111 then moves horizontally to directly below the pad 109. The first translation and lifting module 108 drives the pad 109 downward, bringing it into contact with the cleaning film on the cleaning module 111, completing the cleaning of the pad 109. The cleaning module 111 is equipped with a material sensor. When it senses the presence of material on the cleaning film, the cleaning film reels in and releases the clean film for the next cleaning step. While the pad 109 is printing, the inclined lifting mechanism 300 supports the bottom of the cantilever platform 105, ensuring that the cantilever platform 105 does not deform during pad printing.
