Further, the stepped steel mesh includes a first mesh body 1, a second mesh body 2 and an adjustable mechanism 3, the first mesh body 1 and the second mesh body 2 are arranged in sequence along the first direction X, the adjustable mechanism 3 is arranged between the first mesh body 1 and the second mesh body 2, specifically, the first mesh body 1 and the second mesh body 2 are slidably connected to the adjustable mechanism 3 along the third direction Z, and the first mesh body 1 and the second mesh body 2 are telescopically connected to the adjustable mechanism 3 along the first direction X to adjust the relative height of the first mesh body 1 and the second mesh body 2 along the third direction Z.

[0057] According to the step steel mesh of the embodiment of the utility model, the first mesh body 1 and the second mesh body 2 are adjustably connected by the adjustable mechanism 3. Specifically, on the one hand, the first mesh body 1 is slidably connected to the adjustable mechanism 3 along the third direction Z, and is telescopically connected to the adjustable mechanism 3 along the first direction X, so that the first mesh body 1 can move relative to the adjustable mechanism 3 along the third direction Z to adjust the relative height of the first mesh body 1 and the second mesh body 2 along the third direction Z, thereby forming a step-like structure. On the other hand, the second mesh body 2 is slidably connected to the adjustable mechanism 3 along the third direction Z, and is telescopically connected to the adjustable mechanism 3 along the first direction X, so that the second mesh body 2 can move relative to the adjustable mechanism 3 along the third direction Z, and the relative height of the first mesh body 1 and the second mesh body 2 along the third direction Z can also be adjusted, thereby forming a step-like structure. Compared with the prior art, the embodiment of the present application has lower cost and is also convenient for flexible adjustment of the step steel mesh, and is suitable for more usage scenarios.

[0058] According to some embodiments of the present invention, the stepped steel mesh is used as a special mold for printing circuit boards to transfer solder paste to the circuit board. Figures 1 to 5 As shown, the stepped steel mesh of the present embodiment is applied to a circuit board 200 having a stepped surface. Optionally, the first mesh body 1 and the second mesh body 2 of the stepped steel mesh of the present embodiment have the same size along the third direction Z. When the first mesh body 1 and the second mesh body 2 are not adjusted, the first mesh body 1 and the second mesh body 2 are connected by an adjustable mechanism 3 to form a flat structure. When the first mesh body 1 and the second mesh body 2 are adjusted with the aid of the adjustable mechanism 3, the relative height of the first mesh body 1 and the second mesh body 2 along the third direction Z can be adjusted, so that the first mesh body 1 and the second mesh body 2 are connected to form a stepped structure, which is applied to a circuit board 200 having a stepped surface.

[0059] According to some embodiments of the present invention, Figures 1 to 4 As shown, the adjustable mechanism 3 includes a guide assembly 30, a first sliding member 33 and a second sliding member 34, wherein the first sliding member 33 is arranged between the guide assembly 30 and the first net body 1, and the first sliding member 33 has a first end and a second end that are arranged away from each other along the first direction X, the first end is fixedly connected to the first net body 1, and the second end is slidably connected to the guide assembly 30, that is, the first net body 1 is slidably connected to the guide assembly 30 along the third direction Z through the first sliding member 33, so that when the first net body 1 is pulled, the first net body 1 can move relative to the second net body 2 along the third direction Z; the second sliding member 34 is arranged between the guide assembly 30 and the second net body 2, and the second sliding member 34 has a third end and a fourth end that are arranged away from each other along the first direction X, the third end is fixedly connected to the second net body 2, and the fourth end is slidably connected to the guide assembly 30, that is, the second net body 2 is slidably connected to the guide assembly 30 along the third direction Z through the second sliding member 34, so that when the second net body 2 is pulled, the second net body 2 can move relative to the first net body 1 along the third direction Z. The above structural setting can achieve that the relative height of the first net body 1 and the second net body 2 along the third direction Z can be adjusted by pulling the first net body 1 or pulling the second net body 2, thereby forming a stepped structure, and the operation method is simple and flexible.

[0060] Furthermore, if Figures 1 to 4 As shown, the guide assembly 30 includes a first guide rod 301 and a second guide rod 302 arranged at intervals along the second direction Y. The first guide rod 301 extends along the third direction Z, the second end of the first sliding member 33 is slidably connected to the first guide rod 301, and the first guide rod 301 in the adjustable mechanism 3 is slidably matched with the first sliding member 33 to adjust the position of the first mesh body 1 along the third direction Z. The second guide rod 302 extends along the third direction Z, the fourth end of the second sliding member 34 is slidably connected to the second guide rod 302, and the second guide rod 302 in the adjustable mechanism 3 is slidably matched with the second sliding member 34 to adjust the position of the second mesh body 2 along the third direction Z. In addition, by setting the first guide rod 301 and the second guide rod 302 of the guide assembly 30 in a rod shape, the space occupied between the first mesh body 1 and the second mesh body 2 is small, so as to avoid affecting the printing quality when the circuit board 200 is printed.

[0061] Optionally, the first guide rod 301 and the second guide rod 302 are respectively provided with guide grooves extending along the third direction Z; wherein the first sliding member 33 is provided with a first protrusion, which is slidably disposed in the guide groove of the first guide rod 301; and the second sliding member 34 is provided with a second protrusion, which is slidably disposed in the guide groove of the second guide rod 302. Through the structural cooperation between the guide groove and the first protrusion or the second protrusion, it is ensured that the first guide rod 301 and the first sliding member 33, and the second guide rod 302 and the second sliding member 34 are reliably slidably connected.

[0062] Optionally, the first net body 1 has a first top 101 and a first bottom 102 arranged opposite to each other along the third direction Z, and the second net body 2 has a second top 201 and a second bottom 202 arranged opposite to each other along the third direction Z.

[0063] It should be noted that, when the dimensions of the first mesh body 1 and the second mesh body 2 along the third direction Z are the same, and when the first mesh body 1 and the second mesh body 2 are not adjusted, the first mesh body 1 and the second mesh body 2 are connected by the adjustable mechanism 3 to form a flat plate structure, that is, Figure 1 and Figure 6 As shown, the first top 101 is flush with the second top 201 along the first direction X, and the first bottom 102 and the second bottom 202 are flush along the first direction X. It should also be noted that the dimension of the guide groove provided on the first guide rod 301 along the third direction Z is L1, the dimension of the guide groove provided on the second guide rod 302 along the third direction Z is L2, and the dimension L3 of the first net body 1 and the second net body 2 along the third direction Z must satisfy L1≥L3, and L2≥L3, such as Figure 3 and Figure 4 As shown, it is ensured that by moving the first net body 1 along the third direction Z, or by moving the second net body 2 along the third direction Z, the first bottom 102 of the first net body 1 can be flush with the second top 201 of the second net body 2.

[0064] According to some embodiments of the present invention, Figures 1 to 4As shown, the adjustable mechanism 3 further includes a first connecting component 31 and a second connecting component 32, wherein the first net body 1 is telescopically connected to the guide component 30 along the first direction X through the first connecting component 31, and the second net body 2 is telescopically connected to the guide component 30 along the first direction X through the second connecting component 32. By providing the first connecting component 31 and the second connecting component 32, when the first net body 1 is adjusted relative to the guide component 30 along the third direction Z, the second connecting component 32 ensures that the second net body 2 and the guide component 30 are in a stable state, thereby forming a height difference between the first net body 1 and the second net body 2 in the third direction Z; and when the second net body 2 is adjusted relative to the guide component 30 along the third direction Z, the first connecting component 31 ensures that the first net body 1 and the guide component 30 are in a stable state, thereby forming a height difference between the first net body 1 and the second net body 2 in the third direction Z.

[0065] It should be noted that the first connecting component 31 serves to telescopically connect the first net body 1 to the guide component 30, and the second connecting component 32 serves to telescopically connect the second net body 2 to the guide component 30. However, the first connecting component 31 and the second connecting component 32 do not affect the position adjustment of the first net body 1 and the second net body 2 along the third direction Z.

[0066] Optionally, the first connecting component 31 includes a first connecting member 311 and a second connecting member 312. The first net body 1 is telescopically connected to the first guide rod 301 through the first connecting member 311, and is telescopically connected to the second guide rod 302 through the second connecting member 312. When the first net body 1 and the second net body 2 are connected to form a flat plate structure, the first connecting member 311 and the second connecting member 312 are both extended and retractable along the first direction X. The first connecting member 311 is rotatably connected to the first guide rod 301 and the first net body 1, and the second connecting member 312 is rotatably connected to the second guide rod 302 and the first net body 1. When the first net body 1 moves along the third direction Z relative to the first guide rod 301 through the first sliding member 33, the extension direction of the first connecting member 311 and the second connecting member 312 will also change, and the telescopic direction will also change accordingly, so as to ensure that when the first net body 1 is connected to the first guide rod 301 and the second guide rod 302, it does not affect the sliding of the first net body 1 along the first guide rod 301 along the first sliding member 33.

[0067] Optionally, the second connecting assembly 32 includes a third connecting member 321 and a fourth connecting member 322, and the second net body 2 is telescopically connected to the first guide rod 301 through the fourth connecting member 322, and is telescopically connected to the second guide rod 302 through the third connecting member 321. When the first net body 1 and the second net body 2 are connected to form a flat structure, the third connecting member 321 and the fourth connecting member 322 are both extended and arranged along the first direction X and are telescopic. Among them, the fourth connecting member 322 is rotatably connected to the first guide rod 301 and the second net body 2, and the third connecting member 321 is rotatably connected to the second guide rod 302 and the second net body 2. When the second net body 2 moves along the third direction Z relative to the second guide rod 302 through the second sliding member 34, the extension direction of the third connecting member 321 and the fourth connecting member 322 will also change, and the telescopic direction will also change accordingly, so as to ensure that the second net body 2 is connected to the first guide rod 301 and the second guide rod 302, while not affecting the second net body 2 sliding along the second guide rod 302 along the second sliding member 34.

[0068] Alternatively, if Figures 6 to 8 As shown, the first mesh body 1 has a first side portion 103 and a second side portion 104 arranged opposite to each other along the second direction Y, and the second mesh body 2 has a third side portion 203 and a fourth side portion 204 arranged opposite to each other along the second direction Y, wherein the first side portion 103 and the fourth side portion 204 are flush along the first direction X, and along the first direction X, the first guide rod 301 is located between the first side portion 103 and the fourth side portion 204, and the first sliding member 33 is connected to the first side portion 103 of the first mesh body 1; the second side portion 104 and the third side portion 203 are flush along the first direction X, the second guide rod 302 is located between the second side portion 104 and the third side portion 203, and the second sliding member 34 is connected to the third side portion 203 of the second mesh body 2. The above arrangement enables the various components in the adjustable mechanism 3 for guiding the sliding of the first mesh body 1 and the second mesh body 2 to be distributed as much as possible on both sides of the first mesh body 1 and the second mesh body 2 along the second direction Y, avoiding the part on the circuit board 200 where the solder paste is applied.

[0069] Optionally, the first sliding member 33 and the second sliding member 34 are rod-shaped and both extend along the first direction X, wherein one end of the first sliding member 33 is connected to the first side portion 103 of the first net body 1, and the other end is connected to the first guide rod 301; one end of the second sliding member 34 is connected to the third side portion 203 of the second net body 2, and the other end is connected to the second guide rod 302.

[0070] Optionally, the first connector 311 and the second connector 312 are respectively located on both sides of the first mesh body 1 along the second direction Y, that is, the first connector 311 can be connected to the first side portion 103 of the first mesh body 1, and the second connector 312 can be connected to the second side portion 104 of the first mesh body 1. Distributing the first connector 311 and the second connector 312 on both sides of the first mesh body 1 along the second direction Y as much as possible can also avoid the area on the circuit board 200 where solder paste is applied.

[0071] Optionally, the third connector 321 and the fourth connector 322 are respectively located on both sides of the second mesh body 2 along the second direction Y, that is, the third connector 321 can be connected to the third side portion 203 of the second mesh body 2, and the fourth connector 322 can be connected to the fourth side portion 204 of the second mesh body 2. Distributing the third connector 321 and the fourth connector 322 on both sides of the second mesh body 2 along the second direction Y as much as possible can also avoid the area on the circuit board 200 where solder paste is applied.

[0073] Optionally, this embodiment does not impose any restrictions on the specific connection relationship between the sleeve 3001 and the slide rod 3002 of the first connecting member 311 and the first net body 1 and the first guide rod 301, the specific connection relationship between the sleeve 3001 and the slide rod 3002 of the second connecting member 312 and the first net body 1 and the second guide rod 302, the specific connection relationship between the sleeve 3001 and the slide rod 3002 of the third connecting member 321 and the second net body 2 and the second guide rod 302, and the specific connection relationship between the sleeve 3001 and the slide rod 3002 of the fourth connecting member 322 and the second net body 2 and the first guide rod 301, as long as the first connecting member 311, the second connecting member 312, the third connecting member 321 and the fourth connecting member 322 can respectively achieve their respective functions.

[0074] Alternatively, if Fig.10 As shown, the first connecting member 311, the second connecting member 312, the third connecting member 321 and the fourth connecting member 322 are foldable members, and the foldable members include a first connecting portion 3003, a second connecting portion 3004 and a folding portion 3005 connected between the first connecting portion 3003 and the second connecting portion 3004. The folding portion 3005 is folded so that the first connecting member 311, the second connecting member 312, the third connecting member 321 and the fourth connecting member 322 can be shortened or elongated along their own length direction.

[0076] The specific structures of the retractable member and the foldable member according to the embodiment of the utility model are well known to those skilled in the art and will not be described in detail here.
