The first adjustment structure 22 can clamp the two wide sides of the multi-layer rectangular mesh through two first clamping parts. The second adjustment structure 23 can clamp the two long sides of the multi-layer rectangular mesh through two second clamping parts.

[0022] In some embodiments, the first adjustment structure 22 may be implemented as follows: Figures 1 to 3 See the structure shown. Figures 1 to 3The first adjustment structure 22 includes: a first connection block 221, a sliding block 222, a first vertical plate 223, a first telescopic structure 224 and a first clamping block 225. The first connection block 221 is fixed on the rotating seat 21, and rotates with the rotating seat 21. The first connection block 221 is provided with a first slide groove arranged along the spacing direction of the two wide sides of the multi-layer rectangular mesh to be clamped. The sliding block 222 is slidably arranged in the first slide groove along the extension direction of the long side of the multi-layer rectangular mesh to be clamped. There are two first vertical plates 223, and the two first vertical plates 223 are spaced apart on both sides of the sliding block 222 along the spacing direction of the two wide sides of the multi-layer rectangular mesh to be clamped.

Each first clamping block 225 is arranged on the protruding end of the corresponding first telescopic structure 224, and the corresponding first telescopic structure 224 and the corresponding first clamping block 225 together constitute the first clamping part.

[0023] The first connecting block 221 can be fixed on the rotating seat 21, and the sliding block 222 can slide through the first sliding groove arranged along the spacing direction of the two wide sides of the multi-layer rectangular mesh to be clamped.

[0024] In a specific implementation, the first telescopic structure 224 may be a cylinder. The cylinder is a device that converts the pressure energy of compressed air into mechanical energy and is used to drive the mechanism to perform linear reciprocating motion. The cylinder is a prior art and will not be described in detail here.

[0025] In some embodiments, the first clamping block 225 may be configured as follows: Figure 3 , Figure 4 , Figure 6 , Figure 7 See the structure shown. Figure 3 , Figure 4 , Figure 6 , Figure 7Each first clamping block 225 includes: a fixed slide rail 2251 and a damping slider 2252. The fixed slide rail 2251 is fixedly mounted on the protruding end of the corresponding first telescopic structure 224, and is arranged along the extension direction of the wide side of the multi-layer rectangular mesh. The damping slider 2252 is slidably mounted on the fixed slide rail 2251, and the damping slider 2252 is an L-shaped slider for positioning the multi-layer rectangular mesh.

[0026] The fixed rail 2251 allows the damping slider 2252 to slide along the extension direction of the wide side of the multi-layer rectangular mesh. The damping slider 2252 is L-shaped, and can simultaneously position the length direction and width direction of the multi-layer rectangular mesh. Since the L-shaped has a certain thickness, it can avoid the welding position of the multi-layer rectangular mesh, and avoid the welding point and the damping slider 2252 from being too close.

[0027] The damping slider 2252 can change its position on the fixed slide rail 2251 by sliding to adapt to the clamping of multi-layer rectangular meshes of different sizes.

[0028] It should be noted that a damper is provided on the damping slider 2252. As a core component, the damper can adjust the magnitude of the damping torque through changes in the internal viscous resistance and the force-bearing area.

[0029] In some embodiments, the second adjustment structure 23 may be implemented as follows: Figure 1 , Figure 2 , Figure 3 , Figure 5 See the structure shown. Figure 1 , Figure 2 , Figure 3 , Figure 5 The second adjustment structure 23 includes: a second connection block 231, a second vertical plate 232, a second telescopic structure 233 and a second clamping block 234. The second connection block 231 is fixed on the first connection block 221 and rotates with the rotating seat 21. There are two second vertical plates 232, and the two second vertical plates 232 are spaced apart on both sides of the second connection block 231 along the spacing direction of the two long sides of the multi-layer rectangular mesh to be clamped. There are two second telescopic structures 233, and the two second telescopic structures 233 are arranged in a one-to-one correspondence with the two second vertical plates 232, and each second telescopic structure 233 has an extended end extending toward the positioning space. There are two first clamping blocks 225, and the two second clamping blocks 234 are arranged in a one-to-one correspondence with the two second telescopic structures 233, and each second clamping block 234 is arranged on the extended end of the corresponding second telescopic structure 233, and the corresponding second telescopic structure 233 and the corresponding second clamping block 234 together constitute the second clamping part.

[0030] The second connection block 231 can be fixed on the first connection block 221 and rotate with the rotating seat 21. The two second vertical plates 232 can be understood as connecting plates arranged along the spacing direction of the two long sides of the multi-layer rectangular mesh to be clamped, arranged at intervals on both sides of the second connection block 231 and arranged along the vertical direction, and the two second vertical plates 232 are integrally connected to the second connection block 231. The second telescopic structures 233 can be respectively arranged on the two second vertical plates 232, and the corresponding long sides of the multi-layer rectangular mesh can be abutted by the second clamping blocks 234 on each second telescopic structure 233.

[0031] In a specific implementation, the second telescopic structure 233 may be a cylinder. The cylinder is a device that converts the pressure energy of compressed air into mechanical energy and is used to drive the mechanism to perform linear reciprocating motion. The cylinder is a prior art and will not be described in detail here.

[0032] In some embodiments, the second clamping block 234 may be configured as follows: Figure 3 See the structure shown. Figure 3 Each first clamping block 225 includes: a fixed block 2341 and a contact block 2342. The fixed block 2341 is fixedly mounted on the protruding end of the corresponding first telescopic structure 224. Two contact blocks 2342 are provided, and the two contact blocks 2342 are arranged on the fixed block 2341 at intervals along the extending direction of the long side of the multi-layer rectangular mesh, and the two contact blocks 2342 are used to contact the corresponding long sides of the multi-layer rectangular mesh.

[0033] The fixed block 2341 is integrally connected with the two abutment blocks 2342. The two abutment blocks 2342 can abut on the corresponding long sides of the multi-layer rectangular mesh. The space between the two abutment blocks 2342 can avoid the welding position of the multi-layer rectangular mesh, thereby preventing the welding point from being too close to the fixed block 2341 and the abutment block 2342.

[0034] In some embodiments, the positioning mechanism 20 may be configured as follows: Figures 4 to 7 See the structure shown. Figures 4 to 7Each positioning mechanism 20 also includes a sliding structure 24, which is used to make the sliding block 222 drive the two first clamping blocks 225 to slide along the extension direction of the long side of the multi-layer rectangular mesh when the rotating seat 21 rotates. The sliding structure 24 includes: a fixed cam 241 and a reset spring 242. The fixed cam 241 is fixed on the positioning turntable 11 and is located in the first slide groove. It is used to abut against the sliding block 222 when the rotating seat 21 rotates, so that the sliding block 222 slides along the extension direction of the long side of the multi-layer rectangular mesh to be clamped, so as to reach the welding point of the multi-layer rectangular mesh. There are two reset springs 242, each reset spring 242 is respectively connected to the first vertical plate 223 and the second connecting block 231, and is used to reset the sliding block 222 when the fixed cam 241 does not abut against the sliding block 222.

[0035] The sliding block 222 is provided with a sliding groove for the fixed cam 241 to be placed, and the first connecting block 221 is provided with an arc groove for the fixed cam 241 to pass through when the rotating seat 21 rotates, and the arc groove is connected to the first sliding groove.

[0036] The sliding structure 24 can make the sliding block 222 drive the two first clamping blocks 225 to slide along the extension direction of the long side of the multi-layer rectangular mesh when the rotating seat 21 rotates, so as to adapt to the welding point of the multi-layer rectangular mesh. The fixed cam 241 can be fixed on the positioning turntable 11, and can abut against the sliding block 222 when the rotating seat 21 rotates, so that the sliding block 222 slides along the extension direction of the long side of the multi-layer rectangular mesh to be clamped, so as to reach the welding point of the multi-layer rectangular mesh. The reset spring 242 can reset the sliding block 222 when the fixed cam 241 does not abut against the sliding block 222.

[0037] When the rotating seat 21 rotates, the sliding structure 24 can drive the two first clamping blocks 225 clamping the multi-layer rectangular mesh to move through the abutment between the fixed cam 241 and the sliding block 222. This structure can move the multi-layer rectangular mesh while the rotating seat 21 rotates, avoiding the driving of the first telescopic structure 224 and saving the driving cost of the first telescopic structure 224.

[0038] In some embodiments, the second connecting block 231 may be configured as follows: Figure 3 See the structure shown. Figure 3 A pad 2311 is provided at the top of the second connecting block 231 for placing the multi-layer rectangular mesh, and the pad 2311 is made of copper.

Its main function is to weld after being installed on the outside to protect the appearance quality of the sheet metal. The copper backing plate 2311 is a prior art and will not be described in detail here.

Figure 1 , Figure 8 The spot welding mechanism 40 includes: a fixed frame 41, a lifting structure 42 and a welding gun 43. The fixed frame 41 is fixed on the frame 10. The lifting structure 42 is arranged on the fixed frame 41 and is located above the positioning turntable 11. The lifting structure 42 has an extended end extending downward in the vertical direction. The welding gun 43 is fixed on the extended end of the lifting structure 42 and is used to perform spot welding processing on the midpoint positions of each long side and each wide side of the multi-layer rectangular mesh in the positioning space.

[0041] The fixing frame 41 can be used to install the lifting structure 42, and the lifting structure 42 can drive the welding gun 43 fixed on the extended end of the lifting structure 42 to move in the vertical direction, so as to perform spot welding on the midpoints of the long sides and wide sides of the multi-layer rectangular mesh in the positioning space.

[0042] It should be noted that the welding gun 43 can be understood as a columnar electrode that is powered on. The columnar electrode is an important welding material in resistance welding and is used to transmit current and pressure during the welding process to form a weld.

[0043] The feeding mechanism 30 can be understood as a feeding robot, which can be used as follows: Figure 1 , Fig. 9 See the structure shown.
