[0002] PCB, whose Chinese name is printed circuit board, is also called printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Since it is made by electronic printing, it is called a "printed" circuit board. In the process of processing the circuit board, a punching device is needed to process it. For this reason, China has authorized a utility model patent (Announcement No.: CN220191134U) to disclose a PCB circuit board punching device. In the device, the cooperation of the card slot and the card block can connect and install the chip collection box with the frame. When the device is needed, the chip collection box is first installed to the bottom of the frame, so that the chip collection box can collect the waste chips generated by the circuit board during the drilling process, prevent the waste chips from being exported and splashed, and fall on the ground, thereby affecting the sanitary environment, and it is more time-consuming and laborious to clean up in the later stage.

[0003] The above device still has some shortcomings when in use: in the existing PCB circuit board punching device, when the operator needs to take out the chip box to clean the debris, it is usually necessary to apply downward force to pull the card block out of the card slot. However, in this process, due to improper operation or excessive accumulation of debris in the chip box, it is easy to cause the debris to spill, causing pollution to the working environment. Therefore, a PCB circuit board punching device is proposed to address the above situation. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art that improper operation or excessive accumulation of debris in a chip collecting box easily causes debris to spill and pollute the working environment, and proposes a PCB circuit board punching device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A PCB circuit board punching device comprises two pairs of support columns, a stripping plate, a support plate and a pair of cross bars.

[0007] The crossbar is arranged on a pair of supporting columns, through holes are formed through the crossbar, and one of the crossbars is provided with a pair of positioning holes.

[0008] A pair of damping rotating shafts are arranged on the unloading plate, and both of the damping rotating shafts are matched with the through hole clearances, and one of the damping rotating shafts is fixedly connected with a handle after passing through the through hole.

[0009] The support plate is arranged on two pairs of support columns, and two pairs of collecting boxes are placed on the support plate.

[0010] Preferably, a toggle rod is provided on the handle, and a socket is provided on the toggle rod.

[0011] Preferably, a pin is inserted into the socket, and one end of the pin passes through the socket and extends into the positioning hole.

[0012] Preferably, a workbench is provided on the top of the two pairs of support columns.

[0013] Preferably, the unloading plate is arranged at an angle, and a pair of rectangular protrusions are arranged on the surface of the unloading plate.

[0014] Preferably, a pair of handles are provided on the collection box.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model can accurately guide the debris generated during the punching process into the collection box through the structural design of the cross bar, discharge plate, damping shaft and collection box, effectively avoiding the phenomenon of debris spilling due to improper operation when taking out the chip collection box in the prior art, thereby significantly reducing the pollution of the working environment and the safety risks of the operator. At the same time, the design of two alternately used collection boxes makes it possible to quickly switch to another collection box to continue collecting when one collection box is full, without stopping for cleaning, further improving production efficiency.

[0017] 2. The utility model uses the structural design of the positioning hole, the toggle rod and the latch to further position the unloading plate when the unloading plate is used to guide the debris, thereby ensuring the stability of the unloading plate during operation and further ensuring the smooth collection of the debris during drilling.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4 A PCB circuit board punching device includes two pairs of support columns 1, a discharge plate 4, a support plate 9 and a pair of cross bars 3.

[0025] like Figure 1 As shown, a workbench 2 is provided on the top of the two pairs of support columns 1, and the workbench 2 serves as a platform for punching holes in the PCB circuit board.

[0026] Furthermore, the workbench 2 is a frame structure with a row of hollow grooves on the surface. The workbench 2 is provided with the same punching-related structures and PCB circuit board positioning structures as those in the prior art (Announcement No.: CN220191134U), which will not be elaborated here.

[0027] The crossbar 3 is disposed on a pair of support columns 1 . A through hole 301 is formed through the crossbar 3 . One of the crossbars 3 has a pair of positioning holes 302 .

[0028] A pair of damping shafts 5 are disposed on the discharge plate 4 . The pair of damping shafts 5 are both clearance-matched with the through holes 301 . One of the damping shafts 5 is fixedly connected to a handle 6 after passing through the through hole 301 .

[0029] Further, the unloading plate 4 rotates to Figure 2 In the inclined state shown, a pair of rectangular protrusions are provided on the surface of the discharge plate 4, and the rectangular protrusions can limit the debris to prevent it from falling.

[0030] The support plate 9 is arranged on two pairs of support columns 1 , two pairs of collecting boxes 10 are placed on the support plate 9 , and a pair of handles are arranged on the collecting boxes 10 .

[0031] Through the above structure, the debris generated during the punching process can be accurately guided into the collection box, effectively avoiding the phenomenon of debris spilling due to improper operation when taking out the chip collection box in the prior art, thereby significantly reducing the pollution of the working environment and the safety risks of the operator. At the same time, the design of two alternating collection boxes 10 makes it possible to quickly switch to another collection box 10 to continue collecting when one collection box 10 is full, without stopping for cleaning, further improving production efficiency.

[0032] like Figure 3 and Figure 4 As shown, a toggle rod 7 is provided on the handle 6 , and a plug hole 701 is provided on the toggle rod 7 . A latch pin 8 is inserted into the plug hole 701 , and one end of the latch pin 8 extends into the positioning hole 302 after passing through the plug hole 701 .

[0033] Furthermore, when the discharge plate 4 is used to guide the debris, when one of the collection boxes 10 is full of debris and needs to be cleaned, the discharge plate 4 is rotated counterclockwise so that the discharge plate 4 is tilted toward the other collection box 10. At this time, the toggle rod 7 is rotated from its original position and its position is changed. At this time, after the latch 8 is passed through the socket 701, the latch 8 can enter another positioning hole 302, and the discharge plate 4 can be further positioned to ensure the stability of the discharge plate 4 during operation, thereby ensuring the smooth collection of debris during drilling.
