[0066] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0067] In the description of the present application, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present application, "plurality" means two or more than two, and at least one means one, two or more than two, unless otherwise clearly and specifically defined.

[0068] It should also be noted that in the drawings of the embodiments of the present application, the arrow marked with X represents the second direction X, and the arrow marked with Y represents the first direction Y. In the description of the embodiments of the present application, the intersecting second direction X and first direction Y are introduced to clearly describe the relative position relationship of the various components of the multi-station handling device. It can be understood that the second direction X and the first direction Y are two relative directions rather than absolute directions. In practical applications, the second direction X and the first direction Y can point to any direction in space depending on the way the device is placed. Optionally, the second direction X and the first direction Y are perpendicular to each other. In some embodiments, based on the placement of the circuit board processing device, the second direction X and the first direction Y are two horizontal directions, and accordingly, the Z direction in the drawings is the vertical direction.

[0069] In the related art, when drilling holes in a board during circuit board processing, the distances between the two pin holes (positioning holes) used for positioning in the drilling operation are different due to the inconsistent cutting sizes of the board. There are two main positioning methods: 1. Pre-implant the pins into the circuit board to be processed, and clamp the two positioning pins of any spacing within the corresponding range through the clamping device on the workbench; 2. Pre-implant the pins into the workbench, pre-drill the pin holes on the circuit board, manually place the circuit board on the workbench and insert the pins into the pin holes. Both methods have disadvantages: First, pins are implanted in the circuit board to be processed in advance, and the operator needs to implant pins for circuit boards of different sizes before putting the board on. After the processing is completed, the pins need to be removed, that is, corresponding upper PIN machine and lower PIN machine are required, which increases the equipment cost and the floor space of the plant; Second, pins are implanted in the workbench in advance, which is not conducive to automation. Every time a circuit board of a different size is replaced, the pins need to be re-implanted. The method currently used is to implant pins in the bakelite board, and the bakelite board needs to be replaced regularly; Third, the bakelite board processing method (the method of implanting pins in the workbench in advance) is adopted. If the number of stacks of processed circuit boards is different, that is, the thickness of the circuit boards is different, the height of the pins is also different. If the pins are too low, the upper board cannot be positioned in place; if the original height of the pins is too high, when processing the holes near the pins, it interferes with the presser foot and other devices, affecting the processing and even causing the pins to break.

[0070] In view of this, an embodiment of the present application provides a circuit board processing device, aiming to overcome at least one of the above technical problems. The circuit board processing device is used to process a circuit board, and the circuit board can be a printed circuit board (PCB).

[0071] Please also read Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 8 and Fig. 20 The circuit board processing device of the embodiment of the present application includes a workbench 100 and a plurality of positioning mechanisms 500 .

[0072] The workbench 100 is used to support the circuit board in the circuit board processing device. The workbench 100 is provided with a bearing area 101. The bearing area 101 is an area formed on the workbench 100 for bearing the circuit board 600. The circuit board can be accurately positioned in the bearing area 101 to ensure that the circuit board can be accurately and stably processed.

[0073] A plurality of positioning mechanisms 500 are arranged on the workbench 100 and on the bearing area 101, and the positioning mechanisms 500 are used to position the circuit board in the bearing area 101. Among them, at least one positioning mechanism 500 is arranged in the assembly area 102 and is fixed relative to the position of the workbench 100. The assembly area 102 is located in the bearing area 101 and is symmetrical about the central axis OO' of the bearing area 101. Among them, the assembly area 102 is an area in the bearing area 101 that can be used to assemble the positioning mechanism 500, that is, the range of the bearing area 101 is larger than that of the assembly area 102, and the edge of the bearing area 101 is located at the periphery of the assembly area 102.

[0074] Specifically, a plurality of bearing areas 101 may be provided on the same workbench 100, each bearing area 101 is provided with a corresponding assembly area 102 and is equipped with a plurality of positioning mechanisms 500, wherein at least one positioning mechanism 500 is provided in the assembly area 102. The assembly positions of the plurality of positioning mechanisms 500 in one bearing area 101 may be different from the assembly positions of the plurality of positioning mechanisms 500 in another bearing area 101, and based on the difference in the assembly positions, the boundary ranges of the plurality of bearing areas 101 may also be different.

[0075] At least one positioning mechanism 500 of the circuit board processing device is arranged in the assembly area 102, and the assembly area 102 is arranged in the bearing area 101 and is symmetrical about the central axis OO' of the bearing area 101, and the position of the positioning mechanism 500 relative to the workbench 100 is fixed, so that the position of the positioning mechanism 500 can match the position of the positioning holes of circuit boards of different sizes, so as to adapt to the arrangement of the positioning holes of circuit board sheets of different sizes, which is conducive to promoting automated production, improving production efficiency, and reducing production difficulty.

[0076] It should be noted that in the description of the embodiments of the present application, at least one positioning mechanism 500 is fixed relative to the workbench 100, which means that the position of the positioning mechanism 500 is fixed in the XY plane coordinate system of the workbench 100. In some embodiments, at least part of the structure of the positioning mechanism 500 is movable relative to the workbench along the Z axis.

[0077] Please also read Figures 1 to 4 , Figure 7 and Fig. 9In some embodiments, the bearing area 101 has two first edges 103 arranged opposite to each other along the first direction Y, and at least one positioning mechanism 500 is arranged at the first edge 103 of the bearing area 101, which can meet the edge positioning requirements of a part of the circuit board 600. The circuit board processing equipment also includes a first stopper 200, which is arranged on the workbench 100 and at the first edge 103. The first stopper 200 is used to limit the circuit board placed in the bearing area 101 along the first direction Y. Therefore, when the circuit board is placed on the workbench 100, by abutting one side edge of the circuit board along the first direction Y against the first stopper 200, the first stopper 200 can be used to limit the circuit board in the bearing area 101 and accurately limit the position of the circuit board along the first direction Y.

[0078] See also Figure 1 and Figure 2 In some embodiments, the bearing area 101 further has two second edges 104 arranged opposite to each other along the second direction X, and at least another positioning mechanism 500 is arranged at the second edge 104 of the bearing area 101, so as to meet the requirements of positioning of a part of the circuit board 600 from two edges. The circuit board processing equipment also includes a second stopper 300, which is arranged on the workbench 100 and at the second edge 104, that is, the second stopper 300 and the first stopper 200 are arranged at different edges. The second stopper 300 is used to limit the circuit board along the second direction X, so that by abutting one side edge of the circuit board along the second direction X against the second stopper 300, the second stopper 300 can be used to limit the circuit board in the bearing area 101, and accurately limit the position of the circuit board along the second direction X. Among them, the first direction Y and the second direction X are two intersecting directions, so that the circuit board can be constrained in two directions.

[0079] Please refer again Fig. 20 , the boundary of the assembly area 102 can be determined in the following manner: a circuit board 600 of the smallest size that can be processed by the circuit board processing device is placed in the load-bearing area 101 and is set close to the edge of the load-bearing area 101. In this state, at least one central axis QQ' of the circuit board 600 corresponds to at least one edge of the assembly area 102 in the thickness direction of the circuit board 600. The circuit board 600 is set close to the edge of the load-bearing area 101 so that the edge contour line of the orthographic projection of the circuit board on the workbench 100 falls on the edge of the load-bearing area 101. The circuit board 600 of the smallest size that can be processed by the circuit board processing device satisfies: the board width d of the circuit board 600 of the smallest size is half of the width D of the load-bearing area 101, that is, d=1 / 2D; the board length h of the circuit board 600 of the smallest size is half of the length H of the load-bearing area 101, that is, h=1 / 2H.

[0080] Please also read Figures 3 to 9 In some embodiments, multiple positioning mechanisms 500 are arranged on the central axis OO' of the bearing area 101. This arrangement can meet the edge+center positioning requirements of some circuit boards, and can also meet the center+center positioning requirements of some circuit boards.

[0081] Please read again Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 8 In some embodiments, the circuit board processing device further includes a plurality of clamping members 400 disposed on the workbench 100, and the plurality of clamping members 400 are used to clamp the circuit board placed in the bearing area 101. Among the two clamping members 400 disposed opposite to each other, at least one clamping member 400 can move relative to the workbench 100 toward the other clamping member 400, so as to clamp the circuit board in the bearing area 101.

[0082] In the above embodiment, by setting the first limiting member 200 and the second limiting member 300 on the workbench 100, the circuit board can be limited in the second direction X and the first direction Y, so that the circuit board can be limited in the bearing area 101. By setting a plurality of clamping members 400 on the workbench 100, the circuit board can be clamped by the clamping members 400 to preliminarily fix the circuit board, and then the positioning mechanism 500 located in the bearing area 101 can cooperate with the positioning hole of the circuit board to achieve accurate positioning of the circuit board. The circuit board processing device can be used for circuit boards of different sizes and with the same relative position of the positioning holes. The first limiting member 200 and the second limiting member 300 are used to limit the circuit boards of different sizes. After the circuit boards are clamped and fixed by the clamping members 400, the positioning mechanism 500 can more accurately insert its pin 510 into the positioning hole, thereby improving production efficiency and facilitating production management.

[0083] Please combine Figure 1 and Figure 2 , the relative positions of the two positioning holes of the circuit boards of different sizes are the same, and one positioning method is to use the edge positioning in both the second direction X and the first direction Y. In this positioning method, the circuit boards of different sizes have two common edge areas, and the two positioning holes can be respectively set at the common edge area (such as Figure 2 ), the relative positions of the two positioning holes of circuit boards of different sizes are the same, so that the positions of the two positioning holes of circuit boards of different sizes can be consistent.

[0084] The distances from the two locating holes to the edge of the circuit board are fixed and consistent, which conforms to the current setting rules for pin locating holes on circuit boards (edge ​​principle). Among them, the coordinates (m1, n1) and (m2, n2) of the two locating holes are set according to the corresponding specifications and will not change. The locating holes of all sizes of circuit boards are set according to these coordinates.

[0085] Accordingly, when a circuit board that meets the above-mentioned design specifications is placed on the workbench 100 of the circuit board processing device of some embodiments of the present application, the first limit member 200 and the second limit member 300 can be used to respectively restrain the circuit board against the side, so that the pin 510 of the positioning mechanism 500 can correspond to the position of the positioning hole of the circuit board. After the circuit board is fixed by the clamping member 400, the pin 510 can be inserted into the corresponding positioning hole to realize the positioning of the circuit board.

[0086] Please combine Figure 3 and Figure 4 Another positioning method is to use a combination of edge positioning and center positioning. For this combination positioning method, the positioning hole positions are set according to the overlapping areas of circuit boards of different sizes (such as Figure 4 ), one of the positioning holes on the circuit boards of different sizes is not set close to the edge. The position of the positioning hole is set according to the smallest compatible circuit board size, so the larger the size of the circuit board, the closer this positioning hole is to the middle area of ​​the sheet. The coordinates of the two pin positioning holes are (m3, n3) and (m4, n4), and in general, m3=m4=0. From the coordinate system, it can be seen that for circuit boards with inconsistent Y dimensions in the first direction, the size of the positioning hole (m4, n4) to the opposite side of the circuit board is not fixed, and the manufacturer needs to layout the circuit board circuit according to the position of this positioning hole.

[0087] Accordingly, when a circuit board that meets the above-mentioned design specifications is placed on the workbench 100 of the circuit board processing device of some embodiments of the present application, the first stopper 200 can be used to constrain the circuit board to the side along the second direction X. In the first direction Y, according to the size of the processed circuit board, the second stopper 300 is adjusted to the corresponding position of the workbench 100, so that the circuit board can be constrained along the first direction Y, so that the pin 510 of the positioning mechanism 500 can correspond to the position of the positioning hole of the circuit board. After the circuit board is fixed by the clamp 400, the pin 510 can be inserted into the corresponding positioning hole to realize the positioning of the circuit board.

[0088] Please also read Figure 5 and Figure 6 The third positioning method is to use a combination of center positioning and center positioning. For this combination positioning method, the positioning hole positions are set according to the overlapping areas of circuit boards of different sizes (such as Figure 6), the location of the locating holes should be set according to the smallest compatible PCB size, so the two locating holes are not set close to the edge, but are set with the center of the board as the origin. The coordinates of the two locating holes are (m5, n5) and (m6, n6), and in general, m5=m6=0. From the coordinate system, it can be seen that for PCBs with inconsistent Y dimensions in the first direction, the dimensions of the two pin holes to the opposite sides of the PCB are not fixed. Manufacturers are required to layout the PCB circuits according to the location of the locating holes.

[0089] Accordingly, when a circuit board that meets the above-mentioned design specifications is placed on the workbench 100 of the circuit board processing device of some embodiments of the present application, according to the different sizes of the processed circuit board, in the second direction X, the first limit member 200 is adjusted to the corresponding position of the workbench 100, and in the first direction Y, the second limit member 300 is adjusted to the corresponding position of the workbench 100. This can realize that the first limit member 200 can be used to restrain the circuit board against the edge along the second direction X, and the second limit member 300 can be used to limit the circuit board along the first direction Y, so that the pin 510 of the positioning mechanism 500 can correspond to the position of the positioning hole of the circuit board. After the circuit board is fixed by the clamping member 400, the pin 510 can be inserted into the corresponding positioning hole to realize the positioning of the circuit board.

[0090] In addition to the above three positioning methods, there is also a combination of side positioning and center positioning, please refer to Fig. 9 , which is different from the aforementioned method, in this positioning method, circuit boards of different sizes share one positioning hole (m3, n3), and the position of the other positioning hole is different, that is, n4≠n41≠n42.

[0091] Please also read Figure 7 and Figure 8 In the fourth embodiment, at least one positioning mechanism 500 of the circuit board processing device can move relative to the workbench 100 to approach or move away from another positioning mechanism 500. Thus, at least one pin 510 can be positionally variable in the two-dimensional coordinate system to adapt to different circuit boards.

[0092] like Figure 8 Optionally, the workbench 100 is provided with a fourth driving unit 140, which is connected to the positioning mechanism 500 and is used to drive the positioning mechanism 500 to move relative to the workbench 100. Fig.19 The fourth driving part 140 can be a linear driving structure such as a cylinder or a linear guide. By connecting the positioning mechanism 500 to the fourth driving part 140, the positioning mechanism 500 can be driven by the fourth driving part 140 to adjust its position.

[0093] Accordingly, the circuit board processing device of the fourth embodiment of the present application can be used to process the circuit board that meets the above-mentioned design rules. The first limiter 200 can be used to constrain the circuit board to the side along the second direction X. In the first direction Y, according to the size of the processed circuit board, the second limiter 300 is adjusted to the corresponding position of the workbench 100, and the corresponding circuit board is constrained. The pin 510 of a positioning mechanism 500 of the circuit board processing device can correspond to the position of the positioning hole close to the side, and the position of another positioning mechanism 500 can be adjusted to make its pin 510 correspond to the position of the corresponding positioning hole. After the circuit board is fixed by the clamp 400, the pin 510 can be inserted into the corresponding positioning hole to realize the positioning of the circuit board.

[0094] Please read again Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 8 In some embodiments, along the second direction X, both sides of the bearing area 101 are provided with clamping members 400, and at least one side of the clamping member 400 can move relative to the workbench 100 along the second direction X; along the first direction Y, both sides of the bearing area 101 are provided with clamping members 400, and at least one side of the clamping member 400 can move relative to the workbench 100 along the first direction Y. Therefore, the clamping members 400 can adapt to circuit boards of different sizes, and realize fixing circuit boards of different sizes on the workbench 100.

[0095] For details, please refer to Figure 8 In some embodiments, the workbench 100 is provided with a first driving unit 130, which is connected to the clamping member 400 and is used to drive the clamping member 400 to move relative to the workbench 100 along the second direction X or the first direction Y. The first driving unit 130 can adopt a linear driving structure such as a cylinder and a linear guide rail. By connecting the clamping member 400 to the first driving unit 130, the clamping member 400 can be driven by the first driving unit 130 to adjust its position.

In this embodiment, the transmission part 541 is connected to the bearing part 530, and the movement of the transmission part 541 can push the bearing part 530, so that the bearing part 530 can move, and the pin 510 can be raised or lowered.
