[0048] Refer to Figures 1-14 , a plastic encapsulation device, which includes:

[0049] A bracket 100, the bracket 100 includes two side plates 101 arranged in parallel at intervals. On the top of the bracket 100, a pre - plastic - encapsulation platform 200, a plastic encapsulation machine 300, and a post - plastic - encapsulation platform 400 are sequentially arranged. On the surface of the pre - plastic - encapsulation platform 200, a plastic - encapsulation starting position 201 is provided, and at least one suction cup mechanism 202 is arranged at the bottom of the plastic - encapsulation starting position 201. At the bottom edges of the two side plates 101, several convex edges are provided, which can fix the bracket 100. Fixing the bracket 100 can reduce the vibration of the bracket 100. The pre - plastic - encapsulation platform 200 is the placement position of the plastic - encapsulation film and the original card before plastic encapsulation. The plastic encapsulation machine 300 performs plastic encapsulation, and after plastic encapsulation is completed, it enters the post - plastic - encapsulation platform 400.

[0050] A robotic arm 500, the robotic arm 500 is located on the top of the pre - plastic - encapsulation platform 200 or the post - plastic - encapsulation platform 400. On the one hand, the robotic arm 500 can play the role of picking and placing the original card. At the same time, it can act as a suction cup to suck the upper plastic - encapsulation film, separating the upper plastic - encapsulation film from the lower plastic - encapsulation film. It is a necessary structure to ensure plastic encapsulation and a component to ensure the automatic operation of this device.

[0051] A conveying mechanism 600 feeds the original card and the plastic film into the plastic sealing machine 300 for plastic sealing, and sends out the originally plastic-sealed card. The conveying mechanism 600 can feed the plastic film and the original card on the platform before plastic sealing into the plastic sealing machine 300 for plastic sealing, and at the same time send out the originally plastic-sealed card from the plastic sealing machine 300.

[0052] A telescopic device 700 is installed on the side of the platform 200 before plastic sealing. The telescopic device 700 can extend to the starting position 201 of plastic sealing. The telescopic device 700 mainly functions to keep the upper and lower plastic films separated after they are separated, facilitating the robotic arm 500 to pick up the original card.

[0053] The suction cup mechanism 202 sucks the lower plastic film. The robotic arm 500 sucks the upper plastic film and moves it upward. The telescopic device 700 can extend to block the upper plastic film. The robotic arm 500 inserts the original card between the upper and lower plastic films. The suction cup mechanism 202 sucks the lower plastic film to ensure that the lower and upper plastic films can be separated.

[0054] The working principle of this plastic sealing device is as follows: The robotic arm 500 places the plastic film on the platform 200 before plastic sealing, activates the lower suction cup mechanism 202 to suck the lower plastic film, the robotic arm 500 sucks the tail of the upper plastic film and pushes it forward and upward to make the upper plastic film arch up a certain space, the telescopic device 700 extends to block the upper plastic film, the robotic arm 500 releases the upper plastic film, moves away to pick up the original card, the robotic arm 500 inserts the original card into the sealing position of the plastic film and pushes it into the already activated conveying mechanism 600. The conveying mechanism 600 rolls the original card sandwiched between the plastic films into the plastic sealing machine 300 for plastic sealing. After plastic sealing, it is sent out by the conveying mechanism 600 to the platform 400 after plastic sealing. Then the robotic arm 500 takes away the originally plastic-sealed card, the telescopic device 700 retracts to the initial position, the conveying mechanism 600 stops driving, and waits for the next plastic sealing. This plastic sealing device performs plastic sealing fully automatically, greatly improving the plastic sealing speed and the plastic sealing work efficiency, reducing labor, and lowering the plastic sealing cost.

[0055] As attached Figure 2 to attached Figure 4As shown, in a preferred embodiment, the telescopic device 700 includes a telescopic rod support plate 701, a first motor 702, a telescopic rod 703, a crank 704, a connecting rod 705, a linear guide rail 706, and a slider 707. The bottom end of the telescopic rod support plate 701 is fixed, and the other side extends to the side plate 101 adjacent to it. The first motor 702 is installed on one side of the telescopic rod support plate 701. The crank 704 is connected to the output end of the first motor 702. One end of the crank 704 and the connecting rod 705 are connected by a rolling bearing, and the other end of the connecting rod 705 is connected to the telescopic rod 703 and the slider 707 by a rolling bearing. The first motor 702 drives the slider 707 and the telescopic rod 703 to move linearly. The telescopic device 700 adopts a crank-slider structure. The circular motion of the first motor 702 is converted into the reciprocating motion of the telescopic rod 703 and the slider on the linear guide rail 706 through the crank 704.

[0056] Among them, two opposed sensors 708 are fixed on the telescopic rod support plate 701 on the side where the first motor 702 is installed. The two opposed sensors are respectively located at the starting position and the ending position of the slider 707. Grooves 709 are provided at the bottoms of the two opposed sensors 708. The telescopic rod 703 includes a clamping block 710 that cooperates with the grooves. By inserting the clamping block 710 of the telescopic rod 703 into the grooves 709 of the two opposed sensors 708, the telescopic state of the telescopic rod 703 can be determined. When the clamping block 710 of the telescopic rod 703 is inserted into the opposed sensor 708 at the initial position and the opposed sensor 708 at the initial position is blocked, it is in the retracted state at this time. When the clamping block 710 of the telescopic rod 703 is inserted into the opposed sensor 708 at the ending position and the opposed sensor 708 at the ending position is blocked, it is in the extended state at this time. Fixing two opposed sensors 708 on the telescopic rod support plate 701 can automatically sense the telescopic position, which is convenient for the manipulator and the telescopic rod to perform automatic operations and can be controlled programmatically.

Further, both clamping mechanisms 601 include a roller 603, at least one rubber wheel 604 installed on the roller 603, a floating shaft 605, and a driven wheel 606 installed on the floating shaft 605. The rubber wheel 604 drives the driven wheel 606 to roll. The driven wheel 606 cooperates with the rubber wheel 604 to clamp the original ID card and the plastic film. Pulling springs 607 are fixed at both ends of the floating shaft 605, and the other ends of the pulling springs 607 are fixed on the two side plates 101. The pulling springs 607 make there be a certain pressure between the driven wheel 606 and the rubber wheel 604, so that the original ID card can be rolled in.

[0058] In a specific embodiment, the pulley structure includes a first pulley 608, a second pulley 609, a third pulley 610, and a fourth pulley 611. The output end of the second motor 602 is connected to one end of the roller 603 of the clamping mechanism 601 at the feeding end through the first pulley 608. The roller 603 of the clamping mechanism 601 at the feeding end is connected to one end of the roller 603 of the clamping mechanism 601 at the feeding end through the second pulley 609, the third pulley 610, and the fourth pulley 611.
