[0030] Components are the basic units of electronic products. Once a component fails, it will inevitably lead to electronic product or system failure. Therefore, component failure analysis is an important basis for reliability engineering. When it is necessary to perform failure analysis on components, the components need to be cut off from the circuit board.

[0031] In the related art, the circuit board is usually held by hand and the components to be analyzed are cut off by a cutting part. However, when the components on the circuit board are cut by hand, the cutting direction of the circuit board is unstable, which can easily cause the components to be cut by mistake, affecting the cutting quality of the components on the circuit board, thereby causing other failure modes of the components and making it impossible to obtain accurate analysis conclusions.

[0032] In order to solve the above problems, an embodiment of the present application provides a cutting support device and a cutting machine, which can ensure the stability of the moving direction of the circuit board when the cutting machine cuts the circuit board to cut off the components on the circuit board, thereby improving the cutting quality when the components of the circuit board are cut off from the circuit board.

[0033] like Figure 1 See Figure 3The embodiment of the present application proposes a cutting support device 100, which is used to clamp a circuit board. The cutting support device 100 includes a base 10, a first guide assembly 20, and a clamping assembly 30. The base 10 has a support surface 11. The first guide assembly 20 is disposed on the support surface 11. The clamping assembly 30 is disposed on the first guide assembly 20 and has a degree of freedom of movement along the extension direction of the first guide assembly 20. The clamping assembly 30 includes a first clamping portion 31 and a second clamping portion 32, the first clamping portion 31 and the second clamping portion 32 are at least partially spaced and arranged opposite to each other and form a clamping cavity, and the circuit board can at least partially extend into the clamping cavity and be fixed between the first clamping portion 31 and the second clamping portion 32.

[0034] The extension track of the first guide component includes but is not limited to a straight line track, an arc track or a broken line track, and the extension direction of the first guide component can be understood as the extension direction of the extension track of the first guide component.

[0035] The clamping assembly 30 has the freedom of movement along the extension direction of the first guide assembly 20, which can be understood as the clamping assembly can move relative to the clamping assembly along the extension track of the first guide assembly, and the two can be connected in a sliding manner or in a rolling manner. The clamping assembly can be movably connected to the first guide assembly through one of the first clamping portion and the second clamping portion.

[0036] The extension trajectory of the first guide assembly 20 may include at least one of a straight trajectory, a curved trajectory, and a broken line trajectory.

[0037] The first clamping portion 31 and the second clamping portion 32 of the clamping assembly 30 may be a plate-like structure with concave and convex fitting, or a structure with two flat plates fitting together, or a clamp structure.

[0038] The cutting support device 100 provided in the embodiment of the present application, when in use, the clamping cavity formed by the first clamping portion 31 and the second clamping portion 32 of the clamping assembly 30 fixes the circuit board, and the clamping assembly 30 drives the circuit board to move along the extension direction of the first guide assembly 20, and the circuit board is cut during the movement. Since the circuit board does not need to be held by hand, and the clamping assembly 30 can move along the extension direction of the first guide assembly 20, the moving direction of the circuit board when being cut moves along the extension direction of the first guide assembly 20, which avoids the unstable moving direction of the circuit board when the circuit board is cut by holding the circuit board, resulting in unstable cutting direction of the circuit board, thereby causing the components on the circuit board to be cut incorrectly, so that the moving direction of the circuit board can be stable when the circuit board is cut by the cutting machine, thereby improving the quality of the circuit board being cut, and ensuring the stability of the moving direction of the circuit board when the cutting machine cuts the circuit board to cut off the components on the circuit board, thereby improving the cutting quality of the components on the circuit board when being cut off from the circuit board.

[0039] Continue reading Figure 1 In some optional embodiments, the first guide assembly 20 extends along a straight track, the number of the first guide assemblies 20 is more than two, the more than two first guide assemblies 20 are spaced apart along the first direction X, the first direction X intersects with the extension direction, and the circuit board can be synchronously extended into the clamping cavities of two adjacent first guide assemblies 20.

[0040] The number of the first guide assemblies 20 may be two, three or more.

[0041] The angle between the first direction and the extension direction can be 30°-150°, and can be 90°, that is, the first direction and the second direction can be arranged perpendicularly. According to the cutting support device 100 provided in the embodiment of the present application, at least part of the circuit board is extended into the clamping cavity formed by the first clamping part 31 and the second clamping part 32 of the clamping assembly 30 and fixed, and the clamping assembly 30 drives the circuit board to move along the extension direction of the first guide assembly 20. Since the extension track of the first guide assembly 20 is a straight line, the clamping assembly 30 drives the circuit board to move along the straight track, and then the circuit board is cut along the straight track, ensuring the stability of the moving direction of the circuit board when it is cut. At the same time, since the number of the first guide assemblies 20 is more than two, and each first guide assembly 20 is provided with a clamping assembly 30, the two first guide assemblies 20 are distributed along the first direction X, and at least part of the circuit board can be extended into the clamping cavity of the two adjacent first guide assemblies 20 and fixed together, so that the circuit board is fixed more firmly when it is cut, and the reliability of the cutting support tool for clamping the circuit board is improved.

[0042] like Figure 1-Figure 2 As shown, in some optional embodiments, the first clamping portion 31 includes a first clamping area 31a and a first mounting area 31b distributed along the first direction X. The second clamping portion 32 includes a second clamping area 32a and a second mounting area 32b distributed along the first direction X. The first clamping area 31a and the second clamping area 32a are plate-shaped and form a clamping cavity. The first mounting area 31b is slidably connected to the first guide assembly 20, and the second mounting area 32b is connected to the first mounting area 31b. The second mounting area 32b and the first mounting area 31b can be detachably connected by screws, or can be elastically connected by a torsion spring to form a clamp structure.

[0043] According to the cutting support device 100 provided in the embodiment of the present application, the first clamping area 31a of the first clamping portion 31 and the second clamping area 32a of the second clamping portion 32 are both plate-shaped, so that the clamping cavity formed by the first clamping area 31a and the second clamping area 32a is a strip-shaped clamping cavity. Since the circuit board is also plate-shaped, when at least part of the circuit board is inserted into the clamping cavity and fixed, it can be more closely fitted with the clamping surfaces of the first clamping area 31a and the second clamping area 32a, thereby making the clamping and fixing of the circuit board by the clamping cavity more secure.

[0044] like Figure 1-Figure 3 As shown, in some optional embodiments, the first guide assembly 20 includes a first slide rail and a first slider slidably matched with the first slide rail, the first clamping portion 31 is slidably connected to the first slide rail through the first slider, and the second clamping portion 32 is detachably connected to the first clamping portion 31.

[0045] According to the cutting support device of the embodiment of the present application, the first clamping portion 31 is slidably connected to the first slide rail through the first slider, and the first clamping portion 31 and the second clamping portion 32 are detachably connected. The number of the second clamping portions 32 installed on the first clamping portion 31 can be adjusted according to the size of the circuit board, so that the circuit board fixed to the clamping assembly 30 is more stable, and the clamping assembly 30 drives the circuit board to move along the extension direction of the first guide assembly 20, and the movement is more stable when being cut by the cutting machine.

[0046] like Figure 2-Figure 3 As shown, in some optional embodiments, the cutting support device 100 further includes a second guide assembly 40 extending along the first direction X. The second guide assembly 40 is connected between the base 10 and the first guide assembly 20 , and the first guide assembly 20 has a degree of freedom of movement along the first direction X relative to the second guide assembly 40 .

[0047] According to the cutting support device 100 provided in the embodiment of the present application, since the second guide assembly 40 extending along the first direction X is connected between the base 10 and the first guide assembly 20, and the first guide assembly 20 has a degree of freedom of movement relative to the second guide assembly 40 along the first direction X, the clamping assembly 30 of the first guide assembly 20 can move along the extension direction of the first guide assembly 20, and can also move along the first direction X relative to the second guide assembly 40 with the first guide assembly 20. The circuit board is fixed to the clamping cavity of the clamping assembly 30, and the clamping assembly 30 moves along the extension direction of the first guide assembly 20, so that the moving direction of the circuit board when being cut moves along the extension direction of the first guide assembly 20, thereby ensuring the stability of the moving direction of the circuit board when being cut. At the same time, the circuit board can move along the first direction X relative to the second guide assembly 40 with the first guide assembly 20, so that the cutting support device 100 can adjust the cutting position of the circuit board.

[0048] It can be understood that since the number of the first guide assemblies 20 is more than two, when the clamping assemblies 30 of two adjacent first guide assemblies 20 fix the circuit board together, since the first guide assembly 20 has the freedom of movement relative to the second guide assembly 40 along the first direction X, the two adjacent first guide assemblies 20 can adjust the distance between each other in the first direction X according to the size of the circuit board, thereby completing the fixation of circuit boards of different sizes, thereby improving the versatility of the cutting support device 100 for circuit boards of different sizes.

[0049] Continue reading Figure 2 In some optional embodiments, the number of the second guide components 40 is multiple and they are spaced apart along the extension direction, and each first guide component 20 is slidably connected to each second guide component 40 .

[0050] According to the cutting support device 100 provided in the embodiment of the present application, since the number of the second guide components is multiple and spaced apart along the extension direction, and each first guide component 20 is slidably connected to each second guide component 40, the first guide component 20 is more stable when moving relative to the second guide component 40 along the first direction X.

[0051] like Figure 2-Figure 3 As shown, in some optional embodiments, a first limit member 50 is provided at both ends of the second guide assembly 40 and at least one of the support surface 11 along the first direction X to limit the freedom of movement of the first guide assembly 20 relative to the second guide assembly 40 along the first direction X.

[0052] In some optional embodiments, second limit members 60 are respectively provided at both ends of the first guide assembly 20 along the extension direction to limit the freedom of movement of the clamping assembly 30 relative to the first guide assembly 20 along the extension direction.

[0053] According to the cutting support device 100 provided in the embodiment of the present application, first stoppers 50 are provided at both ends of the second guide assembly 40 and the support surface 11 along the first direction X to limit the freedom of movement of the first guide assembly 20 relative to the second guide assembly 40 along the first direction X, and to prevent the first guide assembly 20 from being separated from the second guide assembly 40 when moving relative to the second guide assembly 40 along the first direction X. Similarly, second stoppers 60 are provided at both ends of the first guide assembly 20 along the extension direction to limit the freedom of movement of the clamping assembly 30 relative to the first guide assembly 20 along the extension direction, and to prevent the clamping assembly 30 from being separated from the first guide assembly 20 when moving relative to the first guide assembly 20 along the extension direction.

[0054] Continue reading Figure 2In some optional embodiments, the base 10 is provided with curling edges facing the support surface 11 at both ends along the first direction X. When the first guide component 20 moves along the first direction X relative to the second guide component 40 to the two ends of the base 10 in the first direction, it can abut against the curling edges. The curling edges can limit the freedom of movement of the first guide component 20 relative to the second guide component 40 along the first direction X to prevent the first guide component 20 from detaching from the second guide component 40 when moving along the first direction X relative to the second guide component 40.

[0055] like Figure 4 and continue to refer to Figure 1 In some optional embodiments, the support surface 11 is provided with a knife hole 12 , and the knife hole 12 is recessed from the support surface 11 toward the inside of the base 10 , and at least part of the knife of the cutting machine can be accommodated in the knife hole 12 .

[0056] According to the cutting support device 100 provided in the embodiment of the present application, when the cutting machine needs to cut the circuit board, the cutting support device 100 can be installed on the cutting machine, and at least part of the tool of the cutting machine can be accommodated in the tool hole 12 and protrude from the support surface 11 of the support seat. The circuit board is fixed to the clamping cavity of the clamping assembly 30 and fixed, and the first guide assembly 20 is adjusted to move relative to the second guide assembly 40 along the first direction X to determine the cutting position of the circuit board, so that the cutting position of the circuit board is aligned with the tool, and then the clamping assembly 30 is adjusted to move along the extension direction of the first guide assembly 20, so that the clamping assembly 30 can move along the extension direction of the first wire assembly to complete the cutting of the circuit board, thereby ensuring the stability of the moving direction when the circuit board is cut.

[0057] It should be noted that the shape of the knife hole 12 can be a strip hole, a round hole or other shapes.

[0058] In some optional embodiments, the support surface 11 is further provided with a plurality of through holes 13, which are distributed around the knife hole 12, so that the cooling water of the cutting tool flows away through the through holes 13 around the tool, thereby preventing the cooling water from accumulating on the support surface 11 of the base 10.

[0059] like Figure 4 and continue to refer to Figure 1 In some optional embodiments, the cutting support device 100 further includes a handle 70 , which is connected to the clamping assembly 30 .

[0060] According to the cutting support device 100 provided in the embodiment of the present application, the handle 70 is connected to the clamping assembly 30. When the circuit board fixed to the first clamping assembly 30 moves along the extension direction of the first guide assembly 20 and is cut by the tool of the cutting machine, the clamping assembly 30 can be pushed by holding the handle 70 to drive the circuit board to move along the extension direction of the first guide assembly 20 to complete the cutting of the circuit board by the cutting machine, so that the user stays away from the tool of the cutting machine during operation, thereby improving the safety of the cutting support device 100 during use.

[0061] An embodiment of the present application further provides a cutting machine, comprising the cutting support device 100 according to any one of the above embodiments of the present application.
