[0032] In some embodiments of the present application, as shown in Figures 1 to 3 The pushing tube mechanism comprises a base 110, a pushing tube clamp 120 and a pushing tube driving member 130. The pushing tube clamp 120 has a clamping groove 121 for clamping the end of the pipe 300. The pushing tube driving member 130 is installed on the base 110, and the output end of the pushing tube driving member 130 is connected with the pushing tube clamp 120, for driving the pushing tube clamp 120 to clamp the pipe 300 and move the pushing tube clamp 120 towards the heat exchanger fin to be penetrated by the pipe. In this way, the pushing tube clamp 120 clamps and drives the pipe 300 to move towards the heat exchanger fin to be penetrated by the pipe, so that the pipe 300 penetrates the heat exchanger fin to be penetrated by the pipe, and the pipe penetration work is completed.

[0033] Optionally, the pushing tube mechanism further comprises a transmission assembly, as shown in Figure 3 and Figure 4 The transmission assembly comprises a rotating shaft 141, an eccentric wheel 142 and a transmission connecting rod 143. The output end of the pushing tube driving member 130 is connected with the rotating shaft 141 to drive the rotating shaft 141 to rotate. The pushing tube driving member 130 can be a motor (for example, a servo motor). The eccentric wheel 142 is fixedly sleeved on the rotating shaft 141. One end of the transmission connecting rod 143 is connected with the eccentric wheel 142, and the other end of the transmission connecting rod 143 is connected with the pushing tube clamp 120. The pushing tube driving member 130 drives the pushing tube clamp 120 to make reciprocating motion in the horizontal direction through the rotating shaft 141, the eccentric wheel 142 and the transmission connecting rod 143, so that the pipe 300 clamped by the pushing tube clamp 120 advances in a shaking manner when penetrating the assembly hole of the heat exchanger fin. The shaking penetration of the pipe 300 into the heat exchanger fin can greatly reduce the resistance during penetration, disperse the instantaneous load of the pushing tube driving member 130, greatly improve the penetration efficiency compared with manual penetration, and will not cause damage to the material. In addition, the shaking advancement of the pipe 300 can timely adjust the direction to accurately penetrate into the assembly hole of the heat exchanger fin, and reduce the penetration failure rate.

In this way, the push tube clamp 120 is elastically connected with the push tube driving member 130, and when the pipe 300 clamped by the push tube clamp 120 is inserted into the assembly hole of the heat exchanger fin, the spring can buffer the pushing force, so as to realize flexible pushing of the pipe 300 into the assembly hole of the heat exchanger fin. In addition, if the pipe 300 is not aligned with the assembly hole of the heat exchanger fin when the pipe 300 is inserted, the spring elastically contracts when the pipe 300 collides with the heat exchanger fin, so as to avoid hard collision between the pipe 300 and the heat exchanger fin, avoid damage of the material, and reduce the failure rate of the pipe insertion operation.

[0035] Optionally, as shown in Figure 4 As shown, the side wall of the end of the first connecting rod 150 connected with the second connecting rod 160 is provided with a strip-shaped hole 151, the side wall of the end of the second connecting rod 160 connected with the first connecting rod 150 is provided with a protrusion 161, and the protrusion 161 is arranged in the strip-shaped hole 151; one end of the protrusion 161 extending out of the strip-shaped hole 151 is provided with a limiting cap 162 for preventing the protrusion 161 from coming out of the strip-shaped hole 151. By arranging the protrusion 161 in the strip-shaped hole 151, the rotation of the second connecting rod 160 relative to the first connecting rod 150 can be prevented, so that the pipe 300 can be accurately inserted into the assembly hole of the heat exchanger fin, the failure rate of the pipe insertion operation is reduced due to the rotation of the second connecting rod 160 and the pipe 300 cannot be aligned with the assembly hole of the heat exchanger fin; at the same time, by arranging the limiting cap 162 to prevent the protrusion 161 from coming out of the strip-shaped hole 151, the second connecting rod 160 can be prevented from coming out of the first connecting rod 150, and the reliability of the push tube mechanism is improved.

The first guide plate 171 plays a guiding role when the first connecting rod 150 moves in the horizontal direction, and the second guide plate 172 plays a guiding role when the transmission connecting rod 143 moves in the horizontal direction.
