[0078] Please see Figures 1 to 13 As shown, this is the first embodiment of the present invention. It should be noted that the accompanying drawings and the related quantities and shapes mentioned in this embodiment are only used to specifically illustrate the implementation of the present invention so as to facilitate understanding of the content of the present invention, and are not intended to limit the scope of protection of the present invention.

[0079] like Figure 1 and Figure 2As shown, the first embodiment of the present invention discloses a vacuum packaging machine 100, which can be used to package multiple circuit board groups 300, and each circuit board group 300 includes multiple circuit boards (not shown) stacked together. In this embodiment, each circuit board is preferably a multi-layer PCB, but the present invention is not limited thereto.

[0081] Specifically, the bag feeding device 1 and the bag sealing device 3 are respectively arranged at intervals between the bag filling device 2, while the labeling device 4 and the storage device 5 are respectively located adjacent to the bag sealing device 3. The bag sealing device 3 is located between the bag filling device 2 and the labeling device 4.

[0082] It should be noted that, for ease of explanation and understanding, the following will describe the bag supply device 1, the bag filling device 2, the bag sealing device 3, the labeling device 4, and the storage device 5 in sequence, and explain the relative positional relationship and operation relationship between the above devices as appropriate.

[0083] like Figures 1 to 3 As shown, the bag feeding device 1 includes a first supporting platform 11, a bag feeding arm 12, and a storage platform 13. The bag feeding arm 12 is spaced above the first supporting platform 11, and the storage platform 13 is spaced beside the first supporting platform 11. The storage platform 13 can store multiple packaging bags 200, and the bag feeding arm 12 can move one of the packaging bags 200 onto the first supporting platform 11.

[0084] Furthermore, such as Figure 1 and Figure 13As shown, the first supporting platform 11 includes a plurality of support forks 111, and each support fork 111 has the same length, while the distance between any two support forks 111 is the same. The length of any one support fork 111 is greater than the side length of any side of the packaging bag 200, and the plurality of support forks 111 can be used to support the packaging bag 200, but the invention is not limited thereto. For example, in other embodiments of the invention not shown, the length, shape, number, etc., of the plurality of support forks 111 can be adjusted according to actual needs.

[0085] Furthermore, the bag supply arm 12 includes a moving mechanism 121, a lifting mechanism 122, and a suction mechanism 123. The moving mechanism 121 is connected to the lifting mechanism 122, and the suction mechanism 123 is connected to the end of the lifting mechanism 122 that is relatively far from the moving mechanism 121. The moving mechanism 121 can be used to move the lifting mechanism 122 above the first support platform 11 or the storage platform 13. The lifting mechanism 122 can be used to move the suction mechanism 123 relative to the first support platform 11 and the storage platform 13. The suction mechanism 123 can be used to pick up a plurality of the packaging bags 200 located on the storage platform 13 and place them on the first support platform 11.

[0086] It should be noted that, in this embodiment, each packaging bag 200 is preferably an aluminum foil antistatic bag, but the present invention is not limited thereto. For example, in other embodiments of the present invention, each packaging bag 200 may also be an electroplated aluminum foil antistatic bag or an electronically transparent vacuum bag.

[0087] The bag feeding device 1 has been introduced here. The bag filling device 2 will now be introduced. Figure 1 and Figures 4 to 7 As shown, the bagging device 2 includes a second support platform 21, a bag opening arm 22, a pushing arm 23, and a bag supporting device 24, but the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the bagging device 2 may not include the bag supporting device 24.

[0088] Specifically, such as Figure 1 and Figure 4 As shown, the second support platform 21 is positioned corresponding to the first support platform 11, and the first support platform 11 is located between the second support platform 21 and the storage platform 13. The bag opening arms 22 are spaced apart on the second support platform 21, the pushing arms 23 are spaced apart on one side of the bag opening arms 22, and the bag supporting device 24 is located between the first support platform 11 and the second support platform 21.

[0089] Furthermore, the bag-opening arm 22 can be used to pick up one side of the packaging bag 200 and move it away from the first support platform 11 in a vertical direction P, so that the packaging bag 200 forms a bag opening 201, and the pushing arm 23 can be used to push the circuit board assembly 300 from the second support platform 21 into the packaging bag 200 through the bag opening 201.

[0090] It should be noted that, for ease of explanation and understanding, the individual structures of the second carrying platform 21, the bag opening arm 22, the pushing arm 23, and the bag supporting device 24 will be described in sequence below.

[0091] like Figure 1 and Figures 4 to 7 As shown, the second support platform 21 includes a plurality of support forks 211 and a lifting mechanism 212 mounted on the plurality of support forks 211. The plurality of support forks 211 can be used to support (have) a circuit board assembly 300, and the lifting mechanism 212 can be used to move the plurality of support forks 211 up and down relative to the first support platform 11. The plurality of support forks 211 of the second support platform 21 are similar in structure and function to the plurality of support forks 111 of the first support platform 11, and will not be described in detail here.

[0092] Furthermore, such as Figures 4 to 7 As shown, the bag-opening arm 22 includes a telescopic mechanism 221 and an opening mechanism 222. The telescopic mechanism 221 is located above the second support platform 21, and the opening mechanism 222 is connected to one end of the telescopic mechanism 221 that is relatively adjacent to the second support platform 21. In this embodiment, the opening mechanism 222 preferably includes a plurality of suction nozzles 2221 arranged in a row, and the arrangement direction of the plurality of suction nozzles 2221 is parallel to the arrangement direction of the plurality of support forks 211.

[0093] Thus, the vacuum packaging machine 100 can open the packaging bag 200 by means of the technical means that "the opening mechanism 222 preferably includes a plurality of suction nozzles 2221 arranged in a row, and the arrangement direction of the plurality of suction nozzles 2221 is parallel to the arrangement direction of the plurality of support forks 211".

[0094] It should be noted that, due to Figures 2 to 7 This is a side view, so only one of the multiple suction nozzles 2221 arranged in a row is shown. However, the actual number of suction nozzles 2221 is still multiple. This is hereby noted.

[0095] like Figure 1 and Figures 4 to 7As shown, the pushing arm 23 includes a moving mechanism 231, a lifting mechanism 232, and a pushing mechanism 233. The moving mechanism 231 is connected to the lifting mechanism 232, and the pushing mechanism 233 is connected to the lifting mechanism 232. In this embodiment, the pushing mechanism 233 is preferably L-shaped, but the invention is not limited thereto.

[0096] Furthermore, the moving mechanism 231 can be used to move the lifting mechanism 232 above the second support platform 21, the lifting mechanism 232 can be used to move the pushing mechanism 233 closer to or further away from the second support platform 21 along the vertical direction P, and the pushing mechanism 233 can be used to move toward the first support platform 11 to push the circuit board assembly 300 into the packaging bag 200.

[0097] like Figures 4 to 7 As shown, the bag-holding device 24 includes two bag-holding mechanisms 241 and a conveying mechanism 242. The two bag-holding mechanisms 241 are positioned corresponding to each other and spaced apart, while the conveying mechanism 242 is located between the two bag-holding mechanisms 241. The two bag-holding mechanisms 241 of the bag-holding device 24 are used to insert and open the bag opening 201, while the conveying mechanism 242 is used to convey the circuit board assembly 300.

[0098] Specifically, such as Figures 4 to 7 As shown, each of the bag-supporting mechanisms 241 includes an expansion plate 2411 and a movable plate 2412, with the movable plate 2412 disposed on the side of the expansion plate 2411 relatively away from the bag opening 201, and the length direction of the expansion plate 2411 being perpendicular to the vertical direction P. The two expansion plates 2411 can be inserted into the bag opening 201, and the two movable plates 2412 can be moved away from each other to allow the expansion plates 2411 to enlarge the opening area of ​​the bag opening 201.

[0099] It should be noted that the length direction of the expansion plate 2411 is perpendicular to the vertical direction P, and in this embodiment, when two expansion plates 2411 are inserted into the bag opening 201, the two expansion plates 2411 occupy at most 0.05 times the opening area of ​​the bag opening 201. Therefore, the expansion plate 2411 can insert into the bag opening 201 with minimal volume and expand the opening area of ​​the bag opening 201.

[0100] Specifically, such as Figures 4 to 7As shown, the conveying mechanism 242 includes a support frame 2421 and a plurality of rollers 2422 mounted on the support frame 2421, and the conveying mechanism 242 can be used to convey the circuit board assembly 300. It should be noted that the conveying mechanism 242 in this embodiment is actually a conventional small roller conveyor belt, so it will not be described in detail here.

[0101] The bagging equipment 2 has been introduced here. The bag sealing equipment 3 will now be introduced. Figure 1 and Figures 8 to 12 As shown, the sealing device 3 can be used to vacuum the packaging bag 200 and seal the bag opening 201. The sealing device 3 includes a sealing device 31 and a moving device 32 spaced apart from the sealing device 31. The moving device 32 can be used to move the packaging bag 200 and the circuit board assembly 300 located inside it on the first support platform 11 to the sealing device 31. The sealing device 31 can be used to vacuum the packaging bag 200 and seal the bag opening 201.

[0102] like Figures 8 to 12 As shown, the moving device 32 includes two moving platforms 321 arranged at intervals, and each of the two moving platforms 321 includes a plurality of support forks 3211. The sealing device 31 includes a vacuum packer 311 and a placement platform 312 located inside the vacuum packer 311, and the placement platform 312 includes a plurality of support forks 3121. One of the moving platforms 321 can be used to move the packaging bag 200 and the circuit board assembly 300 located inside it to the placement platform 312, and the vacuum packer 311 can be used to evacuate the packaging bag 200 and seal the bag opening 201.

[0103] It should be noted that the plurality of support forks 111 of the first carrying platform 11, the plurality of support forks 3211 of the two moving platforms 321, and the plurality of support forks 3121 of the placement platform 312 are similar in shape, and the distance between any two adjacent support forks 111, 3121, 3211 is greater than the width of any one support fork 111, 3121, 3211. Each support fork 111, 3121, 3211 can be used to carry the packaging bag 200 and the circuit board assembly 300, and the plurality of support forks 3211 of any one of the moving platforms 321 can pass through the gaps between the plurality of support forks 111 of the first carrying platform 11 or the plurality of support forks 3121 of the placement platform 312.

[0104] The sealing device 3 has been introduced here. The labeling device 4 will now be introduced. Figure 1As shown, the labeling device 4 includes a label supply device 41 and an affixing arm 42 spaced apart from the label supply device 41. The affixing arm 42 can pick up a label (not shown) from the label supply device 41 and affix it to the packaged circuit board assembly 300.

[0105] The label device 4 has been introduced here. The storage device 5 will now be described. Figure 1 As shown, the storage device 5 includes a plurality of storage units 51 and a distributing arm 52 spaced apart from the plurality of storage units 51. The distributing arm 52 is used to place the packaged circuit board assembly 300 into the plurality of storage units 51. In this embodiment, each storage unit 51 may be a storage platform with a plurality of support forks (not shown) or a box-shaped storage platform. The plurality of support forks are structurally similar to the plurality of support forks 111, and therefore will not be described in detail here.

[0106] It should be noted that one of the multiple support forks 3211 of the mobile platform 321 can be used to pass through the storage device 51 on which the multiple support forks are formed. Thus, the packaged and vacuum-sealed circuit board assembly 300 and the packaging bag 200 can be moved to the storage device 51 on which the multiple support forks are formed.

[0107] [Second Embodiment]

[0108] See Figure 14 As shown, this is the second embodiment of the present invention.

Furthermore, for ease of explanation and understanding, this embodiment will be described in conjunction with the accompanying drawings of the first embodiment described above. The quantities and shapes mentioned in the accompanying drawings are only used to specifically illustrate the implementation of the present invention so as to facilitate understanding of the content of the present invention, and are not intended to limit the scope of protection of the present invention.
