[0035] The following will be combined with the drawings in this embodiment of the utility model to clearly and completely describe the technical solution in this embodiment of the utility model. Obviously, the described embodiment is one embodiment of the utility model, not all embodiments of the utility model. Based on this embodiment of the utility model, all other embodiments of the utility model obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Please refer to Figures 1 to 14 The utility model provides a plate-shaped PCB cutting device.

[0037] like Figure 1 As shown, the plate-like PCB board 11 is provided with three longitudinal waste materials 12 and two transverse waste materials 12. Two cuttings are required at the same time to obtain the strip-shaped PCB board 13 on the right side. The plate-like PCB board 11 is moved transversely and cut twice more after it is in place to obtain the strip-shaped PCB board 13 on the left side. Among them, the longitudinal waste materials 12 naturally fall into the waste material groove 10, and the transverse waste materials 12 are driven by the transverse driving component 5, pass the lower straight knife 65, and fall into the waste material groove 10.

[0038] like Figure 2 As shown, the cutting device includes a frame 1, and the frame 1 includes three parts, wherein the left part is: a storage part for plate-like PCB boards 11, which can be replaced by manual labor in a certain embodiment, and can also be replaced by automated equipment in another embodiment; the middle part is: a PCB board feeding area 4, and the PCB board feeding area 4 is used to temporarily place and feed the plate-like PCB boards 11; the right part is: a PCB board cutting area 7, and the PCB board cutting area 7 is used to cut the incoming plate-like PCB boards 11 to obtain strip-like PCB boards 13.

[0039] like Figure 6 As shown, a transverse driving assembly 5 is installed below the PCB board feeding area 4, and the transverse driving assembly 5 transversely moves the plate-like PCB board 11 on the PCB board feeding area 4 to the PCB board cutting area 7, thereby realizing automatic feeding of the plate-like PCB board 11.

[0040] like Figure 2As shown, the first cutting assembly 61 and the second cutting assembly 62 are respectively installed on both sides of the PCB board cutting area 7. The first cutting assembly 61 and the second cutting assembly 62 are arranged side by side in a transverse direction, and are used to cut the residual material 12 on the plate-like PCB board 11 and cut it into strip-like PCB boards 13; under the drive of the first cutting assembly 61 and the second cutting assembly 62, the plate-like PCB board 11 is automatically cut, and the plate-like PCB board 11 is cut into strip-like PCB boards 13, thereby reducing the labor intensity of manual labor and improving the PCB board cutting efficiency.

[0041] In one embodiment, the strip PCB board 13 can be taken out manually; in another embodiment, it can also be replaced by automated equipment; specifically, a material taking and transferring component 8 for taking the strip PCB board 13 is arranged between the first cutting component 61 and the second cutting component 62, and a residual material groove 10 is arranged at the end of the PCB board cutting area 7, wherein the residual material 12 in the longitudinal direction naturally falls into the residual material groove 10, and the residual material 12 in the transverse direction, driven by the transverse driving component 5, passes over the lower straight knife 65 and falls into the residual material groove 10.

[0042] Further, such as Fig.14 As shown, the material picking and transferring assembly 8 includes a second longitudinal driving member 81 installed on the frame 1, a fifth vertical driving member 82 transmission-connected to the second longitudinal driving member 81, and a plurality of second vacuum suction nozzles 83 installed at the end of the fifth vertical driving member 82; further, in the present embodiment, the cut strip PCB boards 13 need to be taken out in sequence, and the stroke of each movement of the second longitudinal driving member 81 is different, so the second longitudinal driving member 81 adopts a motor-driven moving module, and the longitudinal stroke of the second longitudinal driving member 81 is accurately controlled by the drive of the motor so as to correspond to each strip PCB board 13; the fifth vertical driving member 82 adopts an ordinary vertical cylinder, and the vertical cylinder is used to drive the second vacuum suction nozzle 83 to move downward, and the vertical stroke is a fixed stroke, and the strip PCB board 13 is sucked, and longitudinally transferred under the drive of the second longitudinal driving member 81.

[0043] The movement mode of the cutting device is as follows: first, the plate-like PCB board 11 is manually placed on the PCB board feeding area 4; secondly, the horizontal driving component 5 below the PCB board feeding area 4 horizontally transfers the plate-like PCB board 11 on the PCB board feeding area 4 to the PCB board cutting area 7; thirdly, the first cutting component 61 and the second cutting component 62 simultaneously cut the plate-like PCB board 11 on the PCB board cutting area 7 to obtain a strip-like PCB board 13; finally, the material taking and transferring component 8 performs multiple longitudinal transfers to transfer the strip-like PCB board 13, specifically, the second longitudinal driving member 81 drives the second vacuum suction nozzle 83 to reach above the strip-like PCB board 13, the fifth vertical driving member 82 drives the second vacuum suction nozzle 83 to move downward, sucks the strip-like PCB board 13, and longitudinally transfers it under the drive of the second longitudinal driving member 81, so as to take out the strip-like PCB board 13.

[0044] like Figure 2 As shown, the storage part of the plate-like PCB board 11 is replaced by automated equipment. Specifically, a PCB board transfer component 3 is installed on one side of the PCB board feeding area 4. The PCB board transfer component 3 can pick up the plate-like PCB board 11 and transfer it to the PCB board feeding area 4.

[0045] In order to further automatically convey, the PCB board transfer component 3 cooperates with the vertical drive component 2 on one side to make the conveying efficiency higher; specifically, the vertical drive component 2 is installed opposite to the PCB board transfer component 3, and a plurality of stacked plate-like PCB boards 11 are arranged inside the vertical drive component 2. The vertical drive component 2 is used to move the plate-like PCB board 11 vertically upward, so that the uppermost plate-like PCB board 11 is always maintained at a certain target height, and cooperates with the PCB board transfer component 3. The PCB board transfer component 3 is also always picked up at a certain target height. Specifically, the picking component 31 on the PCB board transfer component 3 moves to the leftmost end, picks up the plate-like PCB board 11 on the vertical drive component 2, and transfers it horizontally to the PCB board feeding area 4.

[0046] The vertical drive assembly 2 and the PCB board transfer assembly 3 cooperate with each other, which can greatly reduce the labor intensity of manual labor. It is only necessary to place multiple stacked plate-like PCB boards 11 on the vertical drive assembly 2 to achieve automatic conveying and feeding of the plate-like PCB boards 11.

[0047] The vertical drive assembly 2 is described in detail below. Figure 3 As shown, a plate-shaped PCB board 11 is placed inside the vertical drive component 2. In actual use, multiple plate-shaped PCB boards 11 can be placed inside the vertical drive component 2 in a stacked manner; Figure 4As shown, the vertical drive assembly 2 includes a first placement plate 21 fixedly connected to the frame 1, a plate-like PCB board 11 is placed on the first placement plate 21, a plurality of limit rods 25 for limiting the plate-like PCB board 11 are arranged around the first placement plate 21, and the limit rods 25 are also provided with a sensing switch 26 for sensing the height of the surface plate-like PCB board 11.

[0048] like Figure 4 As shown, the vertical drive assembly 2 also includes a first vertical drive member 22 mounted on the frame 1 and a lifting plate 23 connected to the first vertical drive member 22. The first vertical drive member 22 drives the lifting plate 23 to reciprocate vertically. The first vertical drive member 22 adopts a vertical moving module driven by a motor, and the vertical stroke of the first vertical drive member 22 is accurately controlled by the drive of the motor, so that the top plate-like PCB board 11 always maintains a certain target height and senses the sensing switch 26.

[0049] Furthermore, the lifting plate 23 is disposed inside the groove 211 on the first placement plate 21 , lifts the plate-shaped PCB board 11 on the first placement plate 21 , and moves vertically upward together under the drive of the first vertical driving member 22 .

[0050] The PCB board transfer component 3 is described in detail below. Figure 5 As shown, the PCB board transfer assembly 3 includes a first horizontal drive member 32 installed on the frame 1, a second vertical drive member 33 transmission-connected to the first horizontal drive member 32, and a picking component 31 installed at the end of the second vertical drive member 33; the first horizontal drive member 32 can adopt a motor-driven horizontal moving module, and can also adopt a driving cylinder, a screw-driven linear module, a synchronous belt-driven linear module or a linear motor module; the second vertical drive member 33 adopts a vertical driving cylinder, which only requires a vertical reciprocating fixed stroke.

[0051] Furthermore, the picking component 31 includes an L-shaped mounting plate 311 and a plurality of first vacuum suction nozzles 312 mounted on the L-shaped mounting plate 311. The first vacuum suction nozzles 312 suck the plate-like PCB board 11 and, driven by the first horizontal driving member 32 and the second vertical driving member 33, transfer it to the PCB board feeding area 4; the first vacuum suction nozzles 312 cover the entire plate-like PCB board 11, thereby facilitating improving the adsorption force on the plate-like PCB board 11.

[0052] In other embodiments, in addition to vacuum adsorption, mechanical claws can also be used for clamping. The mechanical claws can be used to grab the left and right ends of the plate-like PCB board 11 and move it to the PCB board feeding area 4, but the cost is relatively high.

[0053] like Figure 6 As shown, the transverse driving assembly 5 is installed at the lower part of the PCB board feeding area 4, and the transverse driving assembly 5 includes a second transverse driving member 51 installed on the frame 1 and a pushing block 52 drivingly connected to the second transverse driving member 51. The second transverse driving member 51 drives the pushing block 52 to reciprocate laterally. At the same time, the pushing block 52 is located on one side of the plate-like PCB board 11, and the plate-like PCB board 11 is laterally moved to the PCB board cutting area 7.

[0054] Furthermore, the second transverse driving member 51 has multiple transverse strokes, so the second transverse driving member 51 adopts a transverse moving module driven by a motor, and the transverse stroke of the second transverse driving member 51 is accurately controlled by the drive of the motor, so that the plate-shaped PCB board 11 can enter the PCB board cutting area 7 according to the program. Figure 6 As shown, the push block 52 is in the initial position; Figure 7 As shown, when the push block 52 reaches the side of the lower straight knife 65 and is at the end position, the lateral stroke ends and needs to return to the initial position.

[0055] like Fig.10 and Fig.11 As shown, the first cutting assembly 61 and the second cutting assembly 62 have the same structure and both use a knife-type panel splitting assembly. The knife-type panel splitting assembly is a mature existing technology and can be used directly, or can be directly purchased or customized as a finished product.

The first longitudinal driving member 63 adopts a longitudinal cylinder. The first longitudinal driving member 63 drives the upper circular knife 64 to move longitudinally and cooperates with the lower straight knife 65 below to rotate to cut the remaining material 12 on the plate-like PCB board 11.

[0057] In this embodiment, the vertical height of the lower straight knife 65 is higher than the plate-like PCB board 11. In order to allow the plate-like PCB board 11 to pass through the lower straight knife 65 and enter between the first cutting component 61 and the second cutting component 62, and to transfer the residual material 12 in the lateral direction to the inside of the residual material groove 10; the PCB board feeding area 4 and the PCB board cutting area 7 are both equipped with a PCB board upper component 15, and the PCB board upper component 15 is used to vertically lift the plate-like PCB board 11, so that the height of the plate-like PCB board 11 is higher than the lower straight knife 65, so that it can pass through the lower straight knife 65 and be transferred laterally.

[0058] Specifically, Fig.12As shown, the PCB board upper assembly 15 includes a third vertical driving member 16 installed on the frame 1 and a top plate 17 installed at the end of the third vertical driving member 16. The third vertical driving member 16 adopts a vertical cylinder. The third vertical driving member 16 drives the top plate 17 to vertically lift the plate-like PCB board 11 to above the lower straight knife 65, and under the drive of the horizontal driving assembly 5, the plate-like PCB board 11 is moved horizontally to between the first cutting assembly 61 and the second cutting assembly 62, or the residual material 12 in the horizontal direction is transferred to the inside of the residual material trough 10.

[0059] like Figure 6 As shown, the PCB board feeding area 4 includes a second placement plate 41 and a third placement plate 42 installed on the frame 1, and the second placement plate 41 and the third placement plate 42 are arranged side by side longitudinally for placing and feeding the plate-like PCB board 11; one end of the plate-like PCB board 11 is placed on the second placement plate 41, and the other end is placed on the third placement plate 42.

[0060] Furthermore, the second placement plate 41 and the third placement plate 42 are both equipped with a PCB board top assembly 15, and the third vertical driving member 16 drives the top plate 17 to pass through the second placement plate 41 and the third placement plate 42 to lift the plate-like PCB board 11, and under the drive of the horizontal driving assembly 5, the plate-like PCB board 11 is moved horizontally, so that it can easily pass over the lower straight knife 65 and enter between the first cutting assembly 61 and the second cutting assembly 62 for cutting.

[0061] like Figure 8 As shown, the PCB board cutting area 7 includes a fourth placement plate 71, and PCB board top components 15 are installed on both sides of the fourth placement plate 71. The third vertical driving member 16 drives the top plate 17 to pass through the fourth placement plate 71 to lift the plate-like PCB board 11; and under the drive of the horizontal driving component 5, the plate-like PCB board 11 is moved horizontally, and the residual material 12 in the horizontal direction easily passes over the lower straight knife 65 and moves horizontally to enter the residual material groove 10.

[0062] like Figure 8 and Fig. 9 As shown, the fourth placement plate 71 is provided with a first limiting plate 72 for limiting one side of the plate-like PCB board 11, a second limiting plate 76 for limiting the other side of the plate-like PCB board 11, and a plurality of limiting blocks 73 for limiting the end of the plate-like PCB board 11. Specifically, the first limiting plate 72, the second limiting plate 76, the limiting block 73 and the pushing block 52 limit the four sides of the plate-like PCB board 11.

[0063] In order to further limit the plate-like PCB board 11 , L-shaped grooves 74 for accommodating the plate-like PCB board 11 are formed inside the first limiting plate 72 , the second limiting plate 76 and the limiting block 73 .

[0064] In order to press the plate-like PCB board 11 for easy cutting, the first limiting plate 72 and the second limiting plate 76 are both equipped with a plurality of ball screws 75 for pressing the plate-like PCB board 11. The ball screws 75 are internally installed with springs, and the elastic force of the springs is used to press the plate-like PCB board 11.

[0065] like Fig.13 As shown, a PCB board positioning component 9 for positioning the plate-like PCB board 11 is installed in the middle of the fourth placement plate 71, and the PCB board positioning component 9 is arranged below the fourth placement plate 71; the PCB board positioning component 9 includes a fourth vertical drive member 91 installed on the frame 1 and a plurality of positioning pins 92 installed at the end of the fourth vertical drive member 91, and the fourth vertical drive member 91 is a vertical cylinder, which only needs a fixed stroke; specifically, the fourth vertical drive member 91 drives the positioning pins 92 to move vertically upward, pass through the plate-like PCB board 11, and position the plate-like PCB board 11; and also position the cut strip-like PCB board 13; thereby facilitating the adsorption and transfer of the subsequent material picking and transfer component 8.

[0066] The operation steps of the cutting device are as follows:

[0067] Step S1, manually placing a plurality of plate-shaped PCB boards 11 in a stacked manner on the first placement plate 21, the first vertical driving member 22 drives the lifting plate 23 and the plate-shaped PCB boards 11 to rise vertically to a certain target height, and triggers the induction switch 26;

[0068] Step S2, the second vertical driving member 33 drives the first vacuum suction nozzle 312 vertically downward to suck the plate-shaped PCB board 11; and under the drive of the first horizontal driving member 32, it is moved to the PCB board feeding area 4;
