The material to be packaged is placed in the female mold of the hot pressing mold, and the female mold of the hot pressing mold is heated by the heater 33. The telescopic rod of the hydraulic cylinder 31 drives the male mold of the hot pressing mold to press down, so as to realize hot pressing packaging of the material to be packaged.

[0024] The loading and unloading assembly 7 includes a sleeve 73 provided on the surface of the workbench 1, a movable rod 78 inserted in the sleeve 73, a spring 710 provided below the movable rod 78 and a T-shaped mounting platform 71 fixedly connected to the movable rod 78, and the movable rod 78 is located at the center position of the T-shape of the mounting platform 71. The outer wall of the movable rod 78 is provided with a slider 79, and the inner wall of the sleeve 73 is provided with a limiting groove cooperating with the slider 79. The slider 79 cooperates with the limiting groove to realize torque transmission between the sleeve 73 and the movable rod 78. When the movable rod 78 moves downward, the spring 710 is forced to contract. After the force driving the movable rod 78 to move downward disappears, the spring 710 automatically rebounds, pushing the movable rod 78 to move upward and reset. The loading and unloading assembly 7 realizes longitudinal movement and cooperates with the horizontal rotation movement driven by the driving assembly provided inside the workbench 1 to complete the loading and unloading work.

[0025] The material picking and unloading mechanism arranged on the top of the three claws of the T-shaped mounting platform 71 includes three suction cups 76 fixed to the bottom surface of the top of the three claws, three micro air pumps 74 corresponding to the three suction cups 76 and arranged on the top surface of the mounting platform 71, and three driving rods 72 corresponding to the claw arm positions of the three claws and fixed to the bottom surface of the top plate 22.

The height difference is less than or equal to the radius of the universal ball bearing 77. The three suction cups 76 are respectively connected to their corresponding micro air pumps 74 through air pipes 75.

[0026] The driving assembly used in the present invention includes a servo motor fixedly arranged inside the workbench 1. The output shaft of the servo motor passes through the workbench 1 and is transmission-connected to the sleeve 73. When the servo motor is running, it can drive the sleeve 73 to rotate, and in turn drive the movable rod 78 and the mounting platform 71 to rotate.

[0027] The servo motor, hydraulic cylinder 31 and micro air pump 74 are respectively connected to the control system circuit and are controlled by the control system.

[0028] The working principle and working process of this utility model are as follows:

[0029] When the present invention is used, a conveyor belt is used for loading and conveying. The output end of the conveyor belt is aligned with the loading port 4. The lower substrate and the upper substrate are arranged alternately on the conveyor belt. The antenna and the chip are pre-fixed on the lower substrate. The loading port 4 is an open slot whose shape and size match the shape and size of the lower substrate and the upper substrate. Therefore, the lower substrate and the upper substrate will not be misplaced or rotated at an angle during the conveying process. The driving component set inside the workbench 1 drives the mounting table 71 to rotate until the first suction cup in the three claws reaches the top of the loading port 4 and stops rotating. The top surface of the mounting table 71 contacts the universal ball bearing 77 and is subjected to pressure from the driving rod 72, forcing the mounting table 71 to move downward. When the mounting table 71 moves downward, the movable rod 78 moves downward synchronously, and the spring 710 is forced to contract. The three suction cups 76 move synchronously with the mounting table 71. The first suction cup is pressed down into the loading port 4. The first suction cup fits the lower substrate on which the antenna and the chip are fixed, and the corresponding first micro air pump is controlled to start, and the first suction cup is driven through the corresponding air pipe. A negative pressure environment is formed inside the disk, and the lower substrate is adsorbed and fixed by the negative pressure. Then the mounting platform 71 continues to rotate, the claw arm of the mounting platform 71 separates from the universal ball bearing 77, and the spring 710 automatically rebounds, pushing the movable rod 78 to move upward, driving the mounting platform 71 and the suction cup 76 to move upward. The mounting platform 71 pauses after rotating 90 degrees, and the first suction cup reaches the top of the mold mounting groove 32. At the same time, the second suction cup reaches the top of the loading port 4. The driving rod 72 is pressed against the claw arm of the mounting platform 71 again, forcing the mounting platform 71 to move downward. The control system controls the first micro air pump to close, and the first suction cup has no suction. The first suction cup is adsorbed and fixed. The lower substrate is fed into the mother mold of the hot pressing mold, and the second suction cup enters the interior of the feeding port 4 at the same time. The second suction cup is fitted with the upper substrate, and the control system controls the corresponding second micro air pump to start. After the upper substrate is adsorbed and fixed, the mounting table 71 continues to rotate, and the mounting table 71 is separated from the universal ball bearing 77. The mounting table 71 moves upward and resets. The mounting table 71 rotates 90° and pauses again. The second suction cup reaches the top of the mold mounting groove 32, and the second micro air pump is controlled to be closed, and the upper substrate adsorbed and fixed by the second suction cup is sent to the top of the lower substrate transported for the first time. At this time, the third suction cup reaches the top of the feeding port 4, and the corresponding third The first micro air pump is not started, the third suction cup does not absorb and fix the upper or lower substrate, the mounting platform 71 rotates 45 degrees and pauses, the hot pressing assembly 3 starts hot pressing, the heater 33 heats the female mold of the hot pressing mold and the lower and upper substrates inside it, the telescopic rod of the hydraulic cylinder 31 drives the male mold of the hot pressing mold to move downward for hot pressing, after the hot pressing is completed, the telescopic rod of the hydraulic cylinder 31 drives the male mold of the hot pressing mold to move upward and reset, the mounting platform 71 continues to rotate 45 degrees and pauses, the third suction cup reaches the top of the mold mounting groove 32, at this time the driving rod 72 is pressed against the claw arm of the mounting platform 71 again, forcing the mounting platform 71 to move downward,The third suction cup is attached to the RFID electronic tag that has completed hot pressing, and the third micro air pump is started. After the third suction cup adsorbs and fixes the RFID electronic tag that has completed hot pressing, the mounting platform 71 continues to rotate, and the mounting platform 71 is separated from the universal ball bearing 77. The mounting platform 71 moves upward and resets, and then pauses after rotating 90°. The third suction cup reaches the top of the discharge port 6, and the third micro air pump is controlled to be closed, and the RFID electronic tag that has completed hot pressing adsorbed and fixed by the third suction cup is sent to the discharge port 6. The opening side of the discharge port 6 adopts a downward tilt design, and the RFID electronic tag that has completed hot pressing automatically slides down, completing the discharge. Every time the mounting platform 71 rotates 360°, the loading, hot pressing and unloading work can be completed once. When the third suction cup is transferred to the position of the discharge port 6, the first suction cup returns to the top of the loading port 4 and begins to adsorb the lower substrate. This cycle is repeated. The utility model realizes automated packaging work.

[0030] According to production requirements, the loading and unloading components 7 can also adopt various structural forms such as single claw, double claws, etc., and suck the lower substrate and the upper substrate twice at the loading port 4 and move them to the mold mounting groove 32. After the hot pressing process is completed, the RFID electronic tag that has been hot-pressed is sucked again and moved to the unloading port 6.

[0031] The drive rod 72 is used to achieve longitudinal movement in conjunction with the mounting platform 71. It can also be fixed to the mounting platform 71 and rotate with it. Accordingly, the area of the circular motion trajectory on the top plate 22 is provided with through holes or semi-through holes that match the universal ball bearing 77, except for the three positions corresponding to the loading port 4, the unloading port 6, and the mold mounting slot 32. As the drive rod 72 rotates with the mounting platform 71, when it rotates to the loading port 4, the unloading port 6, and the mold mounting slot 32, the drive rod 72 cooperates with the movable rod 78 to move the mounting platform 71 downward to complete the corresponding operation. When the drive rod 72 continues to rotate away from the working position, the mounting platform 71 is lifted and reset.

[0032] Other structural forms such as micro hydraulic cylinders can also be used to achieve longitudinal movement of the mounting platform 71, but the corresponding manufacturing cost is relatively high, which increases the production cost of the enterprise, is not conducive to the development of the enterprise, and the cost-effectiveness is lower than the drive rod 72 designed in this embodiment.
