[0023] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.
[0024] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0025] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0026] For PCB board edge grinding, manual support is typically used to hold the board in place, followed by the use of a roller cutter to trim and grind the edges. However, because the roller cutter vibrates during operation, manual support can cause the PCB board to shift, resulting in some parts of the PCB board not being fully trimmed and ground, thus reducing the accuracy of the trimming and grinding process.
[0027] To address the aforementioned issues, this application provides a cutting and edge-grinding device that can replace manual hand-holding for fixing PCB boards, improving both cutting and edge-grinding accuracy and efficiency.
[0028] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0029] Please see Figure 1A cutting and edge-grinding device includes a fixing component 600 and a grinding component 700. The fixing component 600 includes a first plate 610, a second plate 620, a connecting block 630, and a plurality of holding members 640. One end of the connecting block 630 is disposed on the first plate 610, and the other end of the connecting block 630 is disposed on the second plate 620. A clearance area 650 is provided between the first plate 610 and the second plate 620. Each holding member 640 is disposed at intervals on the first plate 610. Each holding member 640 includes a first driving part 641 and a holding block 642. The first driving part 641 is disposed on the first plate 610, and the holding block 642 is disposed on the first driving part 641. The first driving part 641 is used to drive the holding block 642 to reciprocate in the direction of approaching or moving away from the second plate 620. The grinding component 700 is located on one side of the second plate 620.
[0030] It should be noted that the connecting block 630 fixes the first plate 610 and the second plate 620. When the PCB board passes through the clearance area 650, several holding members 640 will hold and fix the PCB board, replacing the traditional method of manually supporting the PCB board. This improves the cutting and grinding accuracy, as well as the cutting and grinding efficiency.
[0031] Please see Figure 1 and Figure 2 In one embodiment, the grinding assembly 700 includes a horizontal moving member 710, which includes a second driving part 711, a conveyor belt 712, and a base 713. The second driving part 711 is disposed on the conveyor belt 712, and the base 713 is disposed on the conveyor belt 712. Specifically, the grinding assembly 700 also includes a cutting member 720, which includes a first hob 721, a second hob 722, a first support 723, and a third driving part 724. The first hob 721 and the second hob 722 are respectively spaced apart on the first support 723, which is disposed on the base 713. The third driving part 724 is disposed on the first support 723 and is used to drive the first hob 721 and the second hob 722 to rotate.
[0032] It should be noted that the second drive unit 711 is used to move the conveyor belt, which in turn drives the base 713 to move, thereby driving the first roller cutter 721 and the second roller cutter 722 to cut the edge of the PCB board. Furthermore, the third drive unit 724 drives the first roller cutter 721 and the second roller cutter 722 to rotate and cut via a conveyor wheel.
[0033] Preferably, the third drive unit 724, the second drive unit 711 and the first drive unit 641 are all motors.
[0034] Please see Figure 2 and Figure 4In one embodiment, the cutting member 720 further includes a first cutting portion 725, which is disposed on the first roller cutter 721. Specifically, the cutting member 720 further includes a second cutting portion 726, which is disposed on the second roller cutter 722.
[0035] It should be noted that the first cutting part 725 and the second cutting part 726 are areas that contact the edge of the PCB board. They are annular in shape and have high surface hardness.
[0036] Please see Figure 1 , Figure 2 and Figure 5 In one embodiment, the cutting member 720 further includes a second support 727 and an edge grinding block 728. The second support 727 is disposed on the base 713, and the edge grinding block 728 is disposed on the second support 727.
[0037] It should be noted that after the first roller cutter 721 and the second roller cutter 722 have finished cutting, the second support 727, driven by the base 713, drives the edge grinding block 728 to grind the edges of the cut PCB board, making the edges of the PCB board smoother.
[0038] Please see Figure 1 , Figure 2 and Figure 5 In one embodiment, the polishing assembly 700 further includes a cleaning component 730, which includes a debris channel 731 and a suction nozzle 732. The debris channel 731 is disposed on the second support 727, and the suction nozzle 732 is connected to the debris channel 731.
[0039] It is understandable that PCB boards will generate debris during the cutting process. Therefore, in order to prevent debris from scattering everywhere and polluting the environment, the suction nozzle 732 can be connected to an external suction pump to absorb and recycle the debris that falls into the debris channel 731.
[0040] Please see Figure 3 In one embodiment, the fixing component 600 further includes a first fastening seat 660 and a second fastening seat 670, which are respectively spaced apart on the second plate 620.
[0041] It is understandable that the second board 620 will vibrate strongly during the fixing and cutting process of the PCB board. In order to improve the mechanical strength and shock resistance of the second board 620, the first fastening seat 660 and the second fastening seat 670 are respectively installed on both sides of the second board 620 at intervals.
[0042] Please see Figure 1 In one embodiment, the width of the abutment block 642 is greater than or equal to the width of the second plate 620.
[0043] It should be noted that, in order to ensure that the PCB board can be firmly pressed, the width of the supporting block 642 usually needs to be greater than or equal to the width of the second board 620, so as to ensure that the edge of the PCB board can be tightly pressed against the surface of the second board 620.
