The directional terms used are used to illustrate and understand the present invention, and are not used to limit the present invention.

[0033] In the figures, structurally similar elements are denoted by the same reference numerals.

[0034] Please refer to Figure 1In this embodiment, the PCB board cutting device 10 includes a cutting table 20, a cutting mechanism 30, a plurality of manipulator mechanisms 40, a pressing mechanism 50, and a feeding and discharging mechanism 60. A plurality of support bars 21 are arranged on the cutting table 20, and the plurality of support bars 21 are arranged in parallel on the upper surface of the cutting table 20, and a gap 22 is arranged between two adjacent support bars 21. The upper surface of the support bar 21 is used to place the PCB board 70, and the length direction of the support bar 21 is consistent with the conveying direction of the PCB board 70.

[0035] The feeding and discharging mechanism 60 is arranged on one side of the cutting workbench 20, and is used to convey the PCB board 70 to be cut to a set position and convey the cut PCB board 70 out. The cutting mechanism 30 is set above the cutting workbench 20, and is used to cut the PCB board 70 below it. Multiple sets of manipulator mechanisms 40 are arranged at intervals on the other side of the cutting workbench 20. The multiple sets of manipulator mechanisms 40 are used to cooperate with the clamping PCB board 70 to drag along the direction of the cutting mechanism 30 and fix one end of the PCB board 70 during cutting.

[0036] Each set of manipulator mechanisms 40 is correspondingly arranged in a gap 22, and is used to drag the PCB board 70 toward the cutting mechanism 30 and fix the PCB board 70 during cutting. The pressing mechanism 50 is arranged on the side of the cutting mechanism 30 away from the manipulator mechanism 40, and the pressing mechanism 50 is arranged on the side close to the feeding port of the PCB board 70, and is used to cooperate with the manipulator mechanism 40 to press the PCB board 70 during cutting.

[0037] When at least one electronic component is arranged on the PCB board 70, the manipulator mechanism 30 corresponding to the position of the electronic component is separated from the PCB board 70, and other manipulator mechanisms 30 staggered with the electronic components are clamped with the PCB board 70, thereby improving the compatibility of the equipment and thus improving the cutting efficiency.

[0038] In this embodiment, please refer to Figure 2 , Figure 3 , Figure 4 The manipulator mechanism 40 includes a first cylinder 41, a manipulator 42, a second cylinder 43 and a connecting rod 44. The output shaft of the first cylinder 41 is fixedly connected to the manipulator 42. The manipulator 42 is used to clamp the PCB board 70 and drag it along the direction of the cutting mechanism 30. The first driving cylinder 41 is used to drive the manipulator 42 to clamp the PCB board 70 and drag it along the direction perpendicular to the cutting direction. The structure is compact and the cost is low. The second cylinder 43 is arranged obliquely upward, one end of the second cylinder 43 is connected to the end of the first cylinder 41 away from the manipulator 42, and the output shaft of the second cylinder 43 is connected to one end of the connecting rod 44.

[0039] The connecting rod 44 is configured as an L-shaped structure, wherein one end of the connecting rod 44 connected to the output shaft of the second cylinder 43 is vertically configured, and one end of the connecting rod 44 connected to the manipulator 42 is horizontally configured, so as to reasonably utilize space and save costs.

[0040] The manipulator 42 includes a fixed base 421, a first clamping arm 422 and a second clamping arm 423. One end of the first clamping arm 422 and one end of the second clamping arm 423 are both rotatably connected to the fixed base 421, the first clamping arm 422 is located above the second clamping arm 423, and the other end of the connecting rod 44 is connected to the first clamping arm 422 and the second clamping arm 423, and is used to simultaneously drive the other ends of the first clamping arm 422 and the second clamping arm 423 to open or clamp. The structure is simple and cost-saving.

[0041] A position sensor 424 is also provided on the side of the other end of the second clamping arm 423. The position sensor 424 is arranged on the lower surface of the PCB board 70. The position sensor is used to detect whether there is a PCB board 70 above it, thereby improving the working efficiency and stability of clamping.

[0042] The spacing between two adjacent sets of manipulator mechanisms 30 is equal, which improves the compatibility of the equipment and the stability of cutting. Specifically, a set of manipulator mechanisms 40 is arranged in each gap 22, which improves the compatibility of the equipment and the stability of cutting.

[0043] Alternatively, in order to save costs and improve the compatibility of the equipment, the spacing between two adjacent groups of manipulator mechanisms 30 is partially set differently, which can save costs. Specifically, the cutting table 20 is sequentially provided with a first cutting area 23, a second cutting area 24 and a third cutting area 25 along the cutting direction. The distance between the two adjacent groups of manipulator mechanisms 30 located in the second cutting area 24 is set to the first spacing, and the distance between the two adjacent groups of manipulator mechanisms 30 located in the first cutting area 23 and the third cutting area 25 is set to the second spacing. The first spacing is smaller than the second spacing, which increases the center layout density, thereby improving the clamping stability of the PCB board.

[0044] The areas of the first cutting area 23 , the second cutting area 24 , and the third cutting area 25 are all set to be the same, and the second spacing is twice the first spacing, which saves costs.

[0045] Please refer to Figure 1 , Figure 2 In this embodiment, 12 gaps 22 are provided, 8 groups of manipulator mechanisms 40 are provided, and four gaps 22 are provided in the second cutting area 24. Four gaps 22 are provided in the first cutting area 23 and the third cutting area 25, and one group of manipulator mechanisms 40 is provided for each gap 22, so as to improve the compatibility of the equipment and adapt to PCB boards 70 of different sizes.

[0046] Please refer to Figure 5 , Figure 6 , Figure 7 The cutting mechanism 30 includes a lifting platform 31, a cutting tool 32 and a cutting drive assembly 33. The lifting platform 31 is mounted above the cutting workbench 20, the cutting tool 32 is slidably arranged on the lifting platform 31, and the cutting drive assembly 33 is used to drive the cutting tool 32 to slide along the length direction of the lifting platform 31 and cut the PCB board 70.

[0047] Please refer to Figure 5 , Figure 6 , Figure 7 The pressing mechanism 50 includes a lifting assembly 51 and a pressing plate 52. The lifting assembly 51 is arranged on the side of the lifting platform 31 away from the manipulator 42. The lifting assembly 51 is connected to the pressing plate 52 to drive the pressing plate 52 to move up and down along the cutting direction of the PCB board 70. The structure is compact and can also improve the pressing effect of the PCB board 70. The cutting tool 32 and the pressing plate 52 are both located on the same side of the lifting platform 31, which improves the pressing effect and cutting accuracy.

[0048] When in use, the output shaft of the second cylinder 43 retracts, driving the connecting rod 44 to rotate counterclockwise, so that the first clamping arm 422 rotates and clamps the PCB board 70 with the second clamping arm 423. When multiple manipulators 42 drag the PCB board 70 to the cutting area, the control system loosens the manipulator 42 corresponding to the cutting position, that is, the output shaft of the second cylinder 43 extends, thereby driving the connecting rod 44 to rotate clockwise, and the end of the connecting rod 44 loosens the first clamping arm 422 and separates from the end of the second clamping arm 423. The end of the first clamping arm 422 is located above the PCB board 70, and the second clamping arm 423 is connected to the lower surface of the PCB board 70 and fixes the end of the PCB board 70 with other manipulators 42 holding the PCB board 70. The lifting assembly 51 drives the pressing plate 52 to move downward and causes the pressing plate 52 to press and flatten the other side of the PCB board 70 to be cut. The cutting drive assembly 33 drives the cutting tool 32 to cut at the set position.

[0049] Since the pressing plate 52 and the manipulator 42 fix the PCB board 70 at the same time, the fixing performance of the PCB board 70 is good and the stability performance is higher. In addition, since the manipulator 42 is used to fix the edge of the PCB board 70, the pressing area of ​​the manipulator 60 on the PCB board 70 can be adjusted. Therefore, the user can use the manipulator 42 to press different pressing areas based on the need to avoid the position of the cutting port. If the area of ​​the cutting port is small, the manipulator 42 corresponding to the cutting port can be released to vacate the cutting port and improve the efficiency of cutting. If the area of ​​the cutting port is large, while ensuring that the PCB board 70 is fixed and stable, the number of manipulators 60 used to clamp the PCB board 70 at the cutting port position can be reduced accordingly, thereby reducing the pressing area, increasing the cutting area, and improving the accuracy and efficiency of cutting.

[0050] In this embodiment, the utility model relates to a PCB board cutting device, which includes a cutting table, a cutting mechanism, a plurality of sets of manipulator mechanisms and a pressing mechanism. The feeding and discharging mechanism is arranged on one side of the cutting table, and the feeding and discharging mechanism is used to convey the PCB board to be cut to a set position and convey the cut PCB board out. The cutting mechanism is set above the cutting table, and is used to cut the PCB board below it. The plurality of sets of manipulator mechanisms are arranged at intervals on the other side of the cutting table. The plurality of sets of manipulator mechanisms are used to cooperate with the clamping PCB board to drag along the direction of the cutting mechanism and fix one end of the PCB board during cutting. The pressing mechanism is arranged above one side of the feeding and discharging mechanism close to the cutting table, and is used to press the other end of the PCB board. During cutting, the manipulator mechanism plays a dragging role, and the manipulator mechanism presses together with the pressing mechanism, and the manipulator mechanism presses together with the pressing mechanism, which significantly improves the stability of the PCB board and the efficiency of cutting, and solves the problem of poor stability caused by the pressing plate pressing cutting in the prior art.

[0051] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention.
