[0031] As shown in Figures 1 to 5 A slitting device of a PCB, comprising a rack 1, a conveying line 11 for placing a to-be-slitted board 2 is arranged on the rack 1 and is conveyed from an upstream of the rack 1 to a downstream of the rack 1, a cutter die 3 with a preset cutting shape, the cutter die 3 is arranged on the rack 1 in a lifting manner, and the cutter die 3 is used to punch cut the to-be-slitted board 2 on the conveying line 11 when being pressed down, so as to slit the to-be-slitted board 2 into at least one slitted board 21 with the preset cutting shape.

[0032] The cutter die 3 is arranged on the rack 1 in a lifting manner, and the cutter die 3 is used to punch cut the to-be-slitted board 2 on the conveying line 11 when being pressed down, so as to slit the to-be-slitted board 2 into at least one slitted board 21 with the preset cutting shape.

[0033] A first driving member is arranged on the rack 1, and the first driving member is connected with the cutter die 3 to drive the cutter die 3 to lift.

[0034] The guillotine cutter of the traditional slitting machine repeatedly cuts the PCB: for example, when two small PCBs need to be cut, the PCB is cut once by the guillotine cutter; when four small PCBs need to be cut, the PCB is cut twice by the guillotine cutter in sequence, and the whole slitting process is relatively long.

[0035] The scheme is mainly to adjust the cutter on the traditional slitting machine to a die 3, which is driven by the first driving member to rise and fall freely, and the to-be-slitted plate body 2 is moved to the directly below the die 3 by the conveying line 11, and the die 3 only needs to be pressed once to punch the to-be-slitted plate body 2, so that multiple slits 21 can be obtained, without multiple slitting of the to-be-slitted plate body 2, shortening the slitting period and improving the slitting efficiency. And according to the actual demand, the type of the die 3 can be adjusted to slit the to-be-slitted plate body 2 into multiple plate pieces, for example, into two, three or four slits 21.

[0037] As shown in Figure 3 The die 3 is composed of the cutter body 31, the base 32 and the elastic protective pad 33, the cutter body 31 and the elastic protective pad 33 are arranged on the base 32 and move up and down with the base 32, the to-be-slitted plate body 2 is punched by the cutter body 31, and the number of slits 21 punched depends mainly on the shape of the cutter body 31, which is not limited in actual application and can be adjusted according to demand. When the cutter body 31 is pressed, the elastic protective pad 33 will also press the to-be-slitted plate body 2, on the one hand, the to-be-slitted plate body 2 will not move during punching, ensuring cutting accuracy; on the other hand, it also plays a certain protective role on the uncut area.

[0038] Further, the elastic protective pad 33 is a polyurethane foam pad or a sponge pad. The polyurethane foam pad or the sponge pad can be compressed when subjected to pressure, and the compressed polyurethane foam pad or the sponge pad can stably press the to-be-slitted plate body 2 and is not easy to damage the upper surface of the to-be-slitted plate body 2.

[0039] Further, the rack 1 is also provided with a die library 4 and an automatic die changing device, the die library 4 is located on one side of the die 3, a plurality of cutter bodies 31 are arranged in the die library 4, and the automatic die changing device is used to replace the cutter body 31 on the base 32.

[0040] As shown in Figures 3 to 5As shown, a plurality of different types of cutter bodies 31 are stored in the cutter magazine 4. The cutter bodies 31 stored in the cutter magazine 4 are replaced with the cutter bodies 31 on the cutter die 3 by the automatic cutter changing device according to different use requirements. For example, when the number of the slabs 21 to be cut changes, the cutter bodies 31 on the cutter die 3 are replaced. When a slab-shaped cutter body 31 is used to punch the slab 2 once, two small slabs 21 are obtained. When a cross-shaped cutter body 31 is used to punch the slab 2 once, four small slabs 21 are obtained.

[0041] Further, in the horizontal projection plane, the outer contour of the cutter body 31 is in the shape of a line or a cross. The cutter body 31 in the embodiment can be in the shape of a line or a cross, so as to cut the slab 2 into different numbers of slabs 21.

[0043] Further, the conveying line 11 comprises a conveying belt and a second driving member, the output end of the second driving member being connected with the conveying belt to drive the conveying belt to reciprocate along the rack 1.

[0044] The movement of the conveying line 11 is driven by the second driving member. Initially, the conveying line 11 is located at the left side of the cutter die 3 (i.e. the feeding end of the rack 1), so as to facilitate the feeding of the slab 2. During the cutting process, the conveying line 11 is moved to the position directly below the cutter die 3 by the second driving member, so as to cut the slab 2. After the cutting is completed, the conveying line 11 and the slabs 21 are located at the right side of the cutter die 3 (i.e. the discharging end of the rack 1) by the second driving member, so as to facilitate the movement of the slabs 21 to the next process.

[0045] Further, the feeding assembly 5 and the discharging assembly 6 are further included. The feeding assembly 5 is used to move the slab 2 to the conveying line 11. The discharging assembly 6 is used to move the slabs 21 away from the conveying line 11.

[0046] Further, the feeding assembly 5 comprises a feeding conveying belt 51 and a feeding mechanical arm 52. The feeding conveying belt 51 is used to continuously convey the slab 2. The feeding mechanical arm 52 is used to move the slab 2 on the feeding conveying belt 51 to the conveying line 11.

[0047] The discharging assembly 6 comprises a discharging conveying belt 61 and a discharging mechanical arm 62. The discharging mechanical arm 62 is used to move the slabs 21 on the conveying line 11 to the discharging conveying belt 61.

[0048] The continuously transported plate body to be cut 2 on the feeding conveying belt 51 is transported by the feeding manipulator 52 from the feeding conveying belt 51 to the conveying line 11 for subsequent cutting process; when cutting is completed, the conveying line 11 moves to the discharging end on the rack 1, and the separated plate 21 is moved by the discharging manipulator 62 from the conveying line 11 to the discharging conveying belt 61, and the discharging conveying belt 61 transmits the separated plate 21 to the next process, and the entire device has a high degree of intelligence.

[0049] Further, the rack 1 is further provided with a scanning and identifying assembly, which is used to identify whether the plate body to be cut 2 is located at the center position of the conveying line 11.

[0050] The feeding manipulator 52 is further used to move the plate body to be cut 2 to the center position of the conveying line 11 when the scanning and identifying assembly identifies that the plate body to be cut 2 is not located at the center position of the conveying line 11.

[0051] In order to ensure the cutting precision of the plate body to be cut 2, the rack 1 is further provided with a scanning and identifying assembly in the embodiment, which is used to identify whether the plate body to be cut 2 is located at the center position of the conveying line 11; if the plate body to be cut 2 is not located at the center position of the conveying line 11, the cutting may cause the separated plates 21 to have different specifications, which affects the subsequent process; if it is identified that the plate body to be cut 2 is not located at the center position of the conveying line 11, the feeding manipulator 52 is used to move the plate body to be cut 2 to the accurate position, so as to ensure the cutting precision.

[0052] Further, one side of the rack 1 is further provided with a waste conveying machine 71, which is used to convey the remaining PCB plate waste after the separated plate 21 is cut; the discharging end of the waste conveying machine 71 is provided with a waste recycling box 72, which is used to store the remaining PCB plate waste.

[0053] Since the die 3 cuts the plate body to be cut 2 into the separated plate 21 and the remaining PCB plate waste during the cutting process, the PCB plate waste has high recycling value due to containing copper foil and other materials; therefore, the waste conveying machine 71 is arranged at the discharging end of the rack 1, and the remaining PCB plate waste on the conveying line 11 is conveyed to the waste conveying machine 71, and then conveyed to the waste recycling box 72 for collection, which is more energy-saving and environment-friendly.

[0054] The above only describes the preferred embodiments of the present application, and does not limit the patent range of the present application, and any equivalent structural transformation made according to the inventive concept of the present application, or direct / indirect application in other related technical fields is included in the patent protection range of the present application.
