Detailed Implementation

[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] A moisture-proof packaging device for electronic boards, such as Figures 1-6As shown, the device includes a conveying mechanism 1, a feeding mechanism 101, a shielding box 102, a desiccant feeding device 2, an upper winding roller 3, an upper winding film 31, a lower winding roller 4, a lower winding film 41, an unwinding motor 5, a belt 6, a packaging box 7, a second cylinder 8, a sealing plate 9, a take-up roller 10, a take-up motor 11, and a pressing mechanism 12. The feeding mechanism 101 is located on the left side of the conveying mechanism 1, and the desiccant feeding device 2 is located on the upper left end of the conveying mechanism 1. The upper winding roller is rotatably mounted on the upper and lower sides of the conveying mechanism 1. 3 and lower winding roller 4, upper winding roller 3 and lower winding roller 4 are wrapped with belts 6 on the outer rear ends. A shielding box 102 is provided at the rear of the transmission mechanism 1, which wraps the belts 6 inside. An unwinding motor 5 is installed at the rear of the shielding box 102. The output shaft of the unwinding motor 5 extends into the shielding box 102 and is connected to the lower winding roller 4. A packaging box 7 is provided in the middle of the transmission mechanism 1. A second cylinder 8 is installed on the upper side inside the packaging box 7. The piston of the second cylinder 8 is connected to the plastic sealing plate 9. A rotating winding mechanism is provided at the right end of the transmission mechanism 1. The winding roller 10 and the right end of the transmission mechanism 1 are equipped with a take-up motor 11, the output shaft of which is connected to the take-up roller 10. Pressing mechanisms 12 are installed at both ends inside the packaging box 7. A plastic sealing plate 9 is located between the two pressing mechanisms 12. An upper film 31 is wound around the outside of the upper winding roller 3, starting from the upper winding roller 3, passing through the two pressing mechanisms 12 and the underside of the plastic sealing plate 9, and connecting to the take-up roller 10. A lower film 41 is wound around the outside of the lower winding roller 4, starting from the lower winding roller 4. After passing the left end of the transmission mechanism 1, it is closely attached to the upper side of the transmission mechanism 1 and finally connected to the take-up roller 10. The desiccant feeding device 2 includes a mounting frame 21, a storage frame 22, a first cylinder 23 and a push block 24. The mounting frame 21 is provided on the upper side of the transmission mechanism 1. The storage frame 22 is provided on the mounting frame 21. The desiccant is placed in the storage frame 22. The first cylinder 23 is installed in the mounting frame 21. The piston of the first cylinder 23 is connected to the push block 24. The push block 24 is slidably connected to the storage frame 22.

[0027] In use, the feeding mechanism 101 transports the electronic board to the transmission mechanism 1. The transmission mechanism 1 drives the electronic board to move to the right. When the electronic board passes the desiccant feeding device 2, the first cylinder 23 drives the push block 24 to move. The push block 24 pushes the desiccant out of the storage box 22, and the desiccant falls onto the electronic board. The electronic board and the desiccant move together and are located between the upper roll film 31 and the lower roll film 41. The unwinding motor 5 drives the lower roll roller 4 to rotate and unwind. The lower roll roller 4 drives the upper roll roller 3 to unwind synchronously through the belt 6. The winding motor 11 drives the winding roller 10 to wind up. Under the action of the upper roll roller 3, the lower roll roller 4 and the winding roller 10, the upper roll film 31 and the lower roll film 41 move to the right. After the electronic board moves below the sealing plate 9, the second cylinder 8 drives the sealing plate 9 to move downward to package the electronic board and the desiccant. The pressing mechanism 12 will press down the upper roll film 31 to prevent the upper roll film 31 from being too far away from the electronic board and affecting the packaging effect.

[0028] like Figure 3 As shown, the desiccant feeding device 2 also includes an inclined plate 25. An inclined plate 25 is provided on the lower front side of the storage frame 22, and the lower end of the inclined plate 25 is located at the center of the transmission mechanism 1. The inclined plate 25 helps the desiccant to slide more smoothly and land on the electronic board after being pushed by the pusher block 24.

[0029] Both sides of the inclined plate 25 are equipped with baffles. The height of the baffles is higher than the height of the desiccant. The baffles can prevent the desiccant from deviating during the sliding process and ensure that the desiccant can fall accurately onto the electronic board.

[0030] like Figure 6 and Figure 7 As shown, the pressing mechanism 12 includes an adjusting screw 121, a connecting plate 122, a telescopic rod 123, and a pressure roller 124. The adjusting screw 121 is threadedly connected to the middle of both ends of the packaging box 7. The upper end of the adjusting screw 121 is provided with grooves to facilitate rotation. The lower side of the adjusting screw 121 is rotatably connected to the connecting plate 122. The pressure roller 124 is slidably connected to both ends of the packaging box 7. The telescopic rod 123 is connected to the front and rear of the connecting plate 122 and the pressure roller 124. The height of the connecting plate 122 and the pressure roller 124 can be adjusted by rotating the adjusting screw 121 to accommodate electronic boards of different thicknesses.

[0031] like Figure 7 As shown, the pressing mechanism 12 also includes guide rods 126 and a fixing plate 127. Guide rods 126 are provided at both the front and rear ends of the upper side of the connecting plate 122. The upper sides of the two guide rods 126 are connected to the fixing plate 127. Two through holes are provided at both the left and right ends of the upper side of the packaging box 7. The guide rods 126 are slidably connected to the through holes of the packaging box 7. The fixing plate 127 is rotatably connected to the adjusting screw 121. The guide rods 126 and the fixing plate 127 provide stable support and guidance for the adjusting screw 121 and the connecting plate 122, preventing the pressure roller 124 from shifting and affecting the packaging effect.

[0032] like Figure 7 As shown, it also includes an elastic element 125, and the elastic element 125 is connected between the telescopic rod 123 and the connecting plate 122; the elastic element 125 can provide a certain buffering effect to prevent the pressure roller 124 from causing excessive pressure on the upper rolled film 31 during the pressing process and causing it to break.

[0033] like Figure 4 As shown, it also includes guide blocks 13. Guide blocks 13 are provided on both the front and rear sides of the upper side of the transmission mechanism 1. The left side of the opposite side of the two guide blocks 13 is a symmetrical inclined surface. The opposite sides of the two guide blocks 13 are combined to form a Y-shaped channel. The guide blocks 13 can guide the electronic board to maintain the correct position during the transmission process, ensuring that the electronic board can accurately enter the packaging box 7.

[0034] The lower side of the pressure roller 124 of the right-side pressing mechanism 12 is slightly higher than the upper side of the electronic board; this ensures that the electronic board can be smoothly removed from the packaging box 7 after packaging without being blocked by the pressure roller 124 on the right side, thus improving the efficiency and smoothness of material feeding.

[0035] The storage box 22 and the front center of the packaging box 7 are made of transparent material; the transparent material design allows operators to clearly observe the quantity of desiccant and the packaging status of the electronic board, and to replenish the desiccant in a timely manner or to find and resolve problems that occur during packaging.
