Description
Technical Field
[0001] The utility model relates to the technical field of board separators, in particular to a dust collection system for board separators. Background Art
[0002] During the depaneling process of an assembled printed circuit board assembly (PCBA), a milling cutter is used to separate the nodes on the PCBA. However, when the milling cutter cuts the nodes on the PCBA, it will produce dust, which can be trapped on the PCBA or the depaneling jig. To prevent dust from remaining on the PCBA and damaging it, the operator must vacuum the dust remaining on the PCBA or the depaneling jig. In addition, because the width of the stop block on the depaneling machine's vacuum head is 10mm, vertical vacuum leakage occurs if the depaneling hole is larger than 10mm, reducing suction force and resulting in incomplete dust removal. As a result, dust remains on the product (PCBA or depaneling jig), affecting product quality.
[0003] In view of this, there is an urgent need to provide a dust collection system for a board separator. Summary of the Invention

The panel splitter jig is used to carry the PCBA board, and the panel splitter jig is arranged below the milling cutter, and a panel splitter hole is provided corresponding to the bottom of the milling cutter. The dust collection device is used to suck in dust generated when the milling cutter cuts the PCBA board, and the dust collection device is arranged below the panel splitter jig, and has a dust collection head, a dust collection hood and a dust collection tube, and the dust collection hood is arranged between the dust collection head and the dust collection tube. The dust suction head has a dust suction inlet and two stop blocks. The dust suction inlet is arranged between the stop blocks, and the dust suction inlet is arranged corresponding to and directly below the board separation hole, so that the dust generated when the milling cutter cuts the PCBA board is sucked into the dust suction inlet from the board separation hole, and the dust in the dust suction inlet is sucked into the dust suction hood, and the dust in the dust suction hood is sucked into the dust suction pipe.
[0006] Particularly, the board dividing jig further comprises an opening to avoid dust remaining on the PCBA board from being sucked into the dust suction inlet through the opening, the blocking block is arranged below the opening and is used to shield the opening, and the dust suction inlet is arranged below the board dividing hole.

[0015] In order to make the technical problems, technical solutions, and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention. Before describing the present invention in detail, it should be noted that similar components are represented by the same reference numerals in the following description.
[0016] Figure 1 A schematic cross-sectional view of an embodiment of a dust collection system 10 for a panel splitter according to an embodiment of the present invention at an angle. The dust collection system 10 for a panel splitter according to an embodiment of the present invention is suitable for sucking in dust generated after a milling cutter device 110 cuts a PCBA board 100, and has a milling cutter 111. The dust collection system 10 for a panel splitter includes a panel splitter jig 120 and a dust collection device 130. The panel splitter jig 120 is used to carry the PCBA board 100. The panel splitter jig 120 is arranged below the milling cutter 111, and a panel splitting hole 121 is arranged corresponding to the area directly below the milling cutter 111. The dust collection device 130 is used to suck in dust generated when the milling cutter 111 cuts the PCBA board 100. The dust collection device 130 is arranged below the panel splitter jig 120 and has a dust collection head 131, a dust collection hood 132, and a dust collection pipe 133. The dust collection hood 132 is arranged between the dust collection head 131 and the dust collection pipe 133. The dust collection head 131 has a dust collection inlet 134 and two stop blocks 135. The dust collection inlet 134 is disposed between the two stop blocks 135 and is positioned directly below the depaneling hole 121. This allows dust generated when the milling cutter 111 cuts the PCBA board 100 to be drawn through the depaneling hole 121 and circulated into the dust collection inlet 134. The dust in the dust collection inlet 134 is then drawn into the dust collection hood 132 and the dust collection tube 133. It should be noted that the milling cutter device 110 is conventional technology and will not be specifically described. In this case, it is sufficient to note that the milling cutter 111 is disposed directly above the depaneling hole 121 and the dust collection inlet 134 is disposed directly below the depaneling hole 121. In this case, dust generated when the milling cutter 111 cuts the PCBA board 100 can be absorbed by the dust collection device 130. Of course, the shape, appearance, color, function, etc. of the milling cutter device 110 do not need to be particularly concerned about or limited in this case. As long as the milling cutter device 110 has a milling cutter 111, the milling cutter 111 can be used to cut the PCBA board 100 to achieve the purpose of absorbing the dust generated after cutting the PCBA board 100, greatly reducing the product pollution caused by dust residue. In detail, when the milling cutter 111 cuts the PCBA board 100, the dust generated is sucked from the board separation hole 121 of the board separation jig 120 and circulated to the dust suction inlet 134 of the dust suction device 130 (such as Figure 1 S1 in the figure), after the dust in the dust suction inlet 134 is sucked into the dust suction cover 132 (as shown in FIG. Figure 1S2 in the dust collecting cover 132 is sucked into the dust collecting pipe 133 (as shown in FIG. Figure 1 S3 in the figure) to reduce the impact of residual dust on the quality of the PCBA board 100, but the present invention is not limited thereto.
[0017] In order to describe in detail the cooperation between the milling cutter device 110 and the board separation fixture 120 of the dust collection system 10 of the present invention, please refer to Figure 1 and Figure 2 , Figure 2 According to another embodiment of the panel separator dust collection system 10 in another embodiment of the present invention, a cross-sectional schematic diagram at a certain angle. In one embodiment of the present invention, a milling cutter 111 is installed on the milling cutter device 110, and the panel separator jig 120 has a panel separator hole 121, wherein the PCBA board 100 is carried on the upper surface of the panel separator jig 120. It should be noted that the panel separator jig 120 is arranged below the milling cutter 111, and the panel separator hole 121 is correspondingly arranged directly below the milling cutter 111, so that the dust generated by the milling cutter 111 when cutting the PCBA board 100 is sucked into the panel separator hole 121. By the way, there are often many nodes on the PCBA board 100 that need to be cut. It is only necessary to align the moving trajectory of the milling cutter 111 along the direction of the node trajectory, so that the PCBA board 100 can be cut out with the help of the milling cutter 111. Specifically, a splitting hole 121 is provided below each node on the PCBA board 100 that needs to be cut, so that the dust generated when the milling cutter 111 cuts the PCBA board 100 is sucked into the splitting hole 121 and flows to reduce the amount of dust remaining on the PCBA board 100, thereby affecting the quality of the PCBA board 100 and causing product defects. In other words, each node on the PCBA board 100 that needs to be cut is aligned with the splitting hole 121, in order to reduce the amount of dust remaining on the PCBA board 100 through the splitting hole 121, so that the dust generated when the milling cutter 111 cuts the PCBA board 100 is sucked into the dust inlet 134 of the dust collection device 130 through the splitting hole 121 (such as Figure 1 、 Figure 2 Of course, in actual practice, the dust generated when the milling cutter 111 cuts the PCBA board 100 cannot be completely avoided, and the dust cannot be completely avoided from remaining on the PCBA board 100. However, compared with the prior art, the dust remaining on the PCBA board 100 is reduced, thereby reducing the possibility of product defects, but the present invention is not limited to this.
[0018] In order to describe in detail the cooperation between the board separation jig 120 and the dust collection device 130 of the dust collection system 10 of the present invention, please refer to Figure 1. In one embodiment of the present invention, the dust collection device 130 has a dust collection head 131, a dust collection hood 132 and a dust collection tube 133, wherein the dust collection head 131 has a dust collection inlet 134 and two blocking blocks 135, and a dust collection inlet 134 is provided between the two blocking blocks 135, and the dust collection inlet 134 is provided corresponding to the bottom of the partition hole 121. Among them, the opening width of the dust collection inlet 134 is greater than the opening width of the partition hole 121. Simply put, in order to prevent the existence of a dead angle on the dust collection inlet 134 and causing dust to remain on the dust collection inlet 134, the opening width of the dust collection inlet 134 is greater than the opening width of the partition hole 121, so that the dust in the partition hole 121 can be sucked into the dust collection inlet 134. The blocking block 135 is straight cylindrical. The upper end of the dust hood 132 is larger than the lower end, and the cross-section of the dust hood 132 is trapezoidal, thereby sucking the dust belonging to the PCBA board 100 in the dust inlet 134 and circulating it to the dust hood 132. The dust pipe 133 is connected to the lower end of the dust hood 132, thereby sucking the dust belonging to the PCBA board 100 in the dust hood 132 and circulating it to the dust pipe 133. It should be noted that, based on the above, the dust collection device 130 is arranged below the panel separation jig 120, and the dust collection inlet 134 is correspondingly arranged directly below the panel separation hole 121. When the milling cutter 111 cuts the PCBA board 100, the dust generated is sucked from the panel separation hole 121 and circulates to the dust collection inlet 134 (such as Figure 1 S1 in the figure), after the dust in the dust suction inlet 134 is sucked into the dust suction cover 132 (as shown in FIG. Figure 1 S2 in the dust collecting cover 132 is sucked into the dust collecting pipe 133 (as shown in FIG. Figure 1 S3 in the figure). Incidentally, since the height of the baffle 135 is the same as that of the dust collector head 131, the baffle 135 is prevented from having a height difference when it is close to the dust collector head 131 due to the height inconsistency between the baffle 135 and the dust collector head 131, and dust may remain in the height difference between the baffle 135 and the dust collector head 131, but it is not limited to this. It should be noted that there is a height difference between the height of the baffle 135 and the height of the dust collection inlet 134, so the dust in the plate hole 121 will only be sucked into the dust collection inlet 134. The dust hood 132 is arranged between the dust collection head 131 and the dust collection pipe 133, and the dust at the dust collection inlet 134 is sucked into the dust collection pipe 133 by the dust hood 132.
[0019] See also Figure 2In another embodiment of the present invention, the panel separation jig 120 further includes an opening 122. The opening 122 is used to prevent dust remaining on the PCBA board 100 from being sucked through the opening 122 and flowing into the dust suction inlet 134. A blocking block 135 is disposed below the opening 122 to block the opening 122, and a corresponding dust suction inlet 134 is disposed directly below the panel separation hole 121. This allows the blocking block 135 to block the opening 122 while not blocking the panel separation hole 121. In short, the panel separation jig 120 often has openings 122 surrounding the panel separation hole 121, and the blocking block 135 is too short to block the opening 122. As a result, dust from the dust suction inlet 134 enters not only through the panel separation hole 121 but also through the opening 122, resulting in vacuum leakage and causing the dust suction device 130 to fail to cleanly absorb dust. Therefore, it is necessary to increase the width of the blocking block 135 so that the blocking block 135 can cover the opening 122, prevent the dust from not being completely sucked out due to vacuum leakage, and reduce the dust residue on the PCBA board 100, but this is not limited to this. By the way, since the operator counted all the existing panel splitting jigs 120, when the width of the blocking block 135 is 10mm, the panel splitting hole 121 will be larger than 10mm, and there will be a vertical opening 122 that causes vacuum leakage, and no vertical opening 122 exceeding 100mm has been found. Therefore, in another embodiment of the present invention, the width of the blocking block 135 is set to 100mm, hoping to block the opening 122 through the blocking block 135 to prevent the dust residue in the opening 122 from being sucked into the dust suction inlet 134, and the cross-section of the blocking block 135 is rectangular, but this is not limited to this.
[0020] In order to describe in detail the coordination of the components in the dust collection system 10 of the present invention, please refer to Figure 1 and Figure 2In one embodiment of the present invention, when the milling cutter 111 cuts the PCBA board 100, the panel splitting jig 120 is disposed below the milling cutter 111, and the dust suction device 130 is disposed below the panel splitting jig 120. Furthermore, the panel splitting hole 121 is disposed corresponding to directly below the milling cutter 111, and the dust suction inlet 134 is disposed corresponding to directly below the panel splitting hole 121, to prevent the blocking block 135 from blocking the panel splitting hole 121. In addition, if there is an opening 122 around the panel splitting hole 121, the blocking block 135 can block the opening 122 without blocking the panel splitting hole 121, thereby allowing the dust on the panel splitting hole 121 to be sucked into and circulated to the dust suction inlet 134, and preventing the dust in the panel splitting hole 121 from being affected by the opening 122, thereby preventing the dust remaining in the opening 122 from being sucked into and circulated to the dust suction inlet 134. If there is no opening 122 around the board splitting hole 121, there is no need to consider the problem of the opening 122. It is only necessary to make the blocking block 135 not block the board splitting hole 121, so that the dust on the board splitting hole 121 is sucked into the dust suction inlet 134. When the milling cutter 111 cuts the PCBA board 100, the dust generated is sucked into the dust suction inlet 134 from the board splitting hole 121 (such as Figure 1 、 Figure 2 S1 in the figure), the dust in the dust suction inlet 134 is sucked into the dust suction cover 132 (as shown in FIG. Figure 1 、 Figure 2 The dust in the dust collecting cover 132 is then sucked into the dust collecting pipe 133 (eg Figure 1 、 Figure 2 S3 in the figure) is used to improve the dust remaining on the PCBA board 100, thereby preventing the phenomenon of product defects, etc., but the present invention is not limited thereto.
[0021] By the way, in some embodiments of the present invention, the width of the blocking block 135 suitable for the opening 122 in the different splitting jigs 120 can be modified according to actual conditions, so that the blocking block 135 can block the opening 122 and does not block the splitting hole 121, and a dust suction inlet 134 is installed directly below the splitting hole 121. In other words, the splitting hole 121 is provided directly above the opening width of the dust suction inlet 134, so that the dust generated when the milling cutter 111 cuts the PCBA board 100 can be first sucked into the dust suction inlet 134 from the splitting hole 121 (such as Figure 1 、 Figure 2 S1 in the figure), the dust in the dust suction inlet 134 is sucked into the dust suction cover 132 (as shown in FIG. Figure 1 、 Figure 2 The dust in the dust collecting cover 132 is then sucked into the dust collecting pipe 133 (eg Figure 1 、 Figure 2 S3 in the figure) to reduce dust residue on the PCBA board 100, but the present invention is not limited thereto.
[0022] In summary, in the dust collection system 10 of the panel splitter of the present invention, when the milling cutter 111 cuts the PCBA board 100, the panel splitter jig 120 is arranged below the milling cutter 111, and the panel splitting hole 121 is correspondingly arranged directly below the milling cutter 111. The dust collection device 130 is arranged below the panel splitter jig 120, and the dust collection inlet 134 is correspondingly arranged directly below the panel splitting hole 121. Since the opening width of the dust collection inlet 134 is larger than the opening width of the panel splitting hole 121, the dust generated when the milling cutter 111 cuts the PCBA board 100 is sucked from the panel splitting hole 121 and circulated to the dust collection inlet 134 (such as Figure 1 、 Figure 2 After S1 in the dust collection inlet 134 is sucked into the dust collection cover 132 (as shown in FIG. Figure 1 、 Figure 2 The dust in the dust collecting cover 132 is then sucked into the dust collecting pipe 133 (eg Figure 1 、 Figure 2 S3 in the figure further avoids the dust generated when the milling cutter 111 cuts the PCBA board 100 and causes product contamination due to the dust collection device 130 not being able to cleanly collect the dust, thereby causing adverse effects on the product. In addition, when the panel splitting jig 120 also includes an opening 122, a blocking block 135 is provided below the opening 122 and is used to block the opening 122, and a dust collection inlet 134 is provided directly below the panel splitting hole 121. In short, it is necessary to keep the area directly below the opening 122 away from the dust collection inlet 134, and to block the opening 122 and not block the panel splitting hole 121. The above-mentioned setting method reduces the situation of dust residue, is easy to use, and has good practicality, thereby further improving the ease of use of the panel splitting machine dust collection system 10. Furthermore, other purposes and advantages of the present invention can be further understood from the technical features disclosed in the present invention.
[0023] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
