Detailed implementation manners

[0017] The present invention will now be further described in detail with reference to the accompanying drawings.

[0018] Please refer to Figure 1-7 As shown, in this embodiment, a circuit board packaging device is provided, including: a packaging box body 1, a movable table 5 is rotatably fitted in the packaging box body 1, a placing plate 6 is fixedly connected to the upper side of the movable table 5, a sealing cover 2 is arranged in the packaging box body 1, a linear telescopic member 3 fixedly connected to the upper side of the sealing cover 2 is arranged on the upper side of the packaging box body 1, a rectangular cutter 13 and a rectangular heating plate 14 are fixedly connected to the inner side of the sealing cover 2, the rectangular cutter 13 is located outside the rectangular heating plate 14, a vacuum extraction member 11 and a pressure relief member 12 communicated with the sealing cover 2 are arranged on one side of the packaging box body 1, wherein, the linear telescopic member 3 can be any one of a cylinder, a hydraulic cylinder or an electric telescopic rod; A rotating assembly 21 connected to the movable table 5 is arranged inside the side wall of the packaging box body 1, a one-way moving assembly 20 in transmission cooperation with the rotating assembly 21 is arranged on one side of the inner wall of the packaging box body 1, the one-way moving assembly 20 is matched with the sealing cover 2, a filter screen 16 is obliquely arranged below the movable table 5 in the packaging box body 1, and a collection box 15 is arranged below the filter screen 16 in the packaging box body 1; Wherein, a first storage cavity 28 and a second storage cavity 29 are arranged in the collection box 15, and a sponge pad is arranged at the bottom of the first storage cavity 28 to facilitate the protection of the dropped circuit board packaging.

[0019] One application of this embodiment is as follows: When it is necessary to package a circuit board, first place the packaging bottom film on the placement board 6, pick up the circuit board and place it on the packaging bottom film, then place the packaging top film on the circuit board, start the linear telescopic member 3 to drive the sealing cover 2 to move downward. When the sealing cover 2 is above the movable table 5, start the rectangular heating plate 14 and the vacuum extraction member 11. The vacuum extraction member 11 extracts the gas in the sealing cover 2, reducing the air pressure inside the sealing cover 2, causing the packaging bottom film and the packaging top film to adhere to the circuit board. The rectangular heating plate 14 hot-presses and seals the packaging bottom film and the packaging top film, and the rectangular cutter 13 cuts the excess packaging film. After completion, start the pressure relief member 12. After the pressure relief member 12 relieves the negative pressure in the sealing cover 2, the linear telescopic member 3 drives the sealing cover 2 to move upward and reset; When the linear telescopic member 3 drives the sealing cover 2 to move upward and reset, the sealing cover 2 squeezes the one-way moving assembly 20 to drive the rotating assembly 21 to operate, which can drive the movable table 5 to flip inside the packaging box 1, enabling the packaged circuit board on the packaging box 1 and the packaging film corner scraps cut off by the rectangular cutter 13 to automatically fall and discharge. The filter screen 16 screens the packaging film corner scraps and the circuit board packages that fall on the movable table 5, enabling the packaging film corner scraps to fall into the second storage cavity 29 of the collection box 15, and the circuit board packages to fall into the first storage cavity 28. It should be noted that all electrical equipment involved in this application can be powered by a storage battery or an external power source.

[0020] By providing the rectangular cutter 13 and the rectangular heating plate 14 inside the sealing cover 2, when the linear telescopic member 3 drives the sealing cover 2 to move downward, while the heated rectangular heating plate 14 hot-presses and seals the packaging film on the circuit board, the rectangular cutter 13 cuts the excess packaging film, ensuring that the edge of the circuit board package is neat and eliminating the need for secondary edge cutting; by providing the one-way moving assembly 20 inside the packaging box 1, when the linear telescopic member 3 drives the sealing cover 2 to move upward and reset, the sealing cover 2 squeezes the one-way moving assembly 20 to drive the rotating assembly 21 to operate, which can drive the movable table 5 to flip inside the packaging box 1, enabling the packaged circuit board on the packaging box 1 and the packaging film corner scraps cut off by the rectangular cutter 13 to automatically fall and discharge, reducing the need for individual removal, thereby improving the packaging efficiency of the circuit board; by providing the inclined filter screen 16 inside the packaging box 1, when the movable table 5 flips, it can screen the packaging film corner scraps and the circuit board packages that fall on the movable table 5, enabling the packaging film corner scraps to fall into the second storage cavity 29 of the collection box 15, and the circuit board packages to fall into the first storage cavity 28, thus facilitating the classified placement of the circuit board packages and the packaging film corner scraps.

[0021] As Figure 2As shown in the figure, a sealing groove 7 corresponding to the sealing cover 2 is formed on the upper side of the movable table 5 of this embodiment, and a sealing rubber strip 8 is arranged in the sealing groove 7; a cutting groove 9 corresponding to the rectangular cutter 13 is formed on the upper side of the movable table 5, a protective plate is arranged in the cutting groove 9, and a heat-sealing groove 10 corresponding to the rectangular heating plate 14 is formed on the upper side of the movable table 5. Among them, the sealing rubber strip 8 improves the sealing performance between the sealing cover 2 and the movable table 5, and the protective plate can be a rubber plate or a wooden plate, which can protect the blade of the rectangular cutter 13; As Figure 2 shown, specifically, the specific structure of the vacuum extraction member 11 is as follows: an air extraction pump 1102 arranged on one side of the packaging box body 1, and a first telescopic hose 1101 fixedly connected to the air inlet of the air extraction pump 1102 and communicating with the sealing cover 2; the pressure relief member 12 includes a pressure relief valve 1202 arranged on one side of the packaging box body 1, and a second telescopic hose 1201 fixedly connected to the air inlet of the pressure relief valve 1202 and communicating with the sealing cover 2.

[0022] When the linear telescopic member 3 drives the sealing cover 2 to move downward into the sealing groove 7, start the rectangular heating plate 14 and the air extraction pump 1102. The air extraction pump 1102 extracts the gas in the sealing cover 2 through the first telescopic hose 1101, so that the air pressure inside the sealing cover 2 is reduced to form a negative pressure, so that the packaging bottom film and the packaging top film are attached to the circuit board. The rectangular heating plate 14 squeezes the packaging bottom film and the packaging top film into the heat-sealing groove 10, and the rectangular heating plate 14 thermally presses and seals the packaging bottom film and the packaging top film entering the heat-sealing groove 10. The rectangular cutter 13 cuts the extra packaging film. After completion, open the pressure relief valve 1202. After the pressure relief valve 1202 is opened and the negative pressure in the sealing cover 2 is relieved through the second telescopic hose 1201, the linear telescopic member 3 drives the sealing cover 2 to move upward and reset.

[0023] As Figure 3 shown, an inner cavity 18 is arranged inside one side of the packaging box body 1 of this embodiment, a rotating rod 17 fixedly connected to one side of the movable table 5 is rotatably fitted in the inner cavity 18, and the rotating assembly 21 is connected to the rotating rod 17; As Figure 4 shown, specifically, the specific structure of the rotating assembly 21 is as follows: a first gear 2101 in interference fit with the circumferential side of the rotating rod 17, a first toothed plate 2102 located in the inner cavity 18 and meshing with the first gear 2101, the first toothed plate 2102 is in transmission cooperation with the one-way moving assembly 20, and a return spring 22 is fixedly connected between the first toothed plate 2102 and the inner cavity 18. Among them, the return spring 22 can reset the first toothed plate 2102 to drive the movable table 5 to reset in the packaging box body 1; As Figure 4 shown, a through groove 19 communicating with the inner cavity 18 is formed on one side of the inner wall of the packaging box body 1 of this embodiment; As Figure 5-6As shown in the figure, specifically, the specific structure of the unidirectional moving component 20 is as follows: a connecting plate 2001 located in the through groove 19, a limiting groove opening 2002 opened on one side of the connecting plate 2001, a rotating shaft 2003 rotatably and elastically fitted in the limiting groove opening 2002, and a movable plate 2004 fixedly connected to the periphery of the rotating shaft 2003 and corresponding to the sealing cover 2; a return torsion spring 26 is sleeved on the periphery of the rotating shaft 2003, and both ends of the return torsion spring 26 are fixedly connected to the through groove 19 and one side of the movable plate 2004 respectively; a movable rod 24 is rotatably fitted in the through groove 19, a second gear 25 is in interference fit with the periphery of the movable rod 24, a second toothed plate 23 meshing with the second gear 25 is fixedly connected to the upper side of the first toothed plate 2102, and the connecting plate 2001 is fixedly connected to one side of the second gear 25.

[0024] When the linear telescopic member 3 drives the sealing cover 2 to reset upward, the top of the sealing cover 2 presses the movable plate 2004 upward. The upward movement of the movable plate 2004 drives the connecting plate 2001 to flip upward through the reset of the limiting groove opening 2002. The upward flipping of the connecting plate 2001 drives the second gear 25 to rotate through the movable rod 24. The rotation of the second gear 25 drives the second toothed plate 23 to move downward. The downward movement of the second toothed plate 23 drives the first toothed plate 2102 to move downward. The downward movement of the first toothed plate 2102 drives the first gear 2101 to rotate. The rotation of the first gear 2101 drives the rotating rod 17 to rotate. The rotation of the rotating rod 17 drives the movable table 5 to flip in the packaging box body 1, enabling the packaged circuit board on the packaging box body 1 and the packaging film corner materials cut off by the rectangular cutter 13 to automatically fall and discharge. The filter screen 16 screens the packaging film corner materials and circuit board packages falling on the movable table 5, enabling the packaging film corner materials to fall into the second storage cavity 29 of the collection box 15, and the circuit board packages to fall into the first storage cavity 28; After the linear telescopic member 3 drives the sealing cover 2 to be completely reset upward, the return torsion spring 26 drives the movable plate 2004 to reset through the elastic force. The return spring 22 enables the first toothed plate 2102 to reset through the elastic force and drives the movable table 5 to reset in the packaging box body 1, enabling the circuit board to be packaged cyclically, thereby improving the packaging efficiency of the circuit board.
