After the U-shaped tube 10 is shaped, the carrying platform 220 slides away from the shaping mold 230, and then the robot 400 conveys the shaped U-shaped tube 10 to the collecting mechanism 300. The U-tube material collecting machine provided by the invention can realize automatic feeding, automatic processing and automatic discharging, improves the automation level and the working efficiency of the U-tube 10 shaping processing, and solves the technical problem that the existing U-tube 10 shaping processing needs manual feeding and manual discharging.

The U-tube 10 is formed by bending a straight tube from the middle. The end of the U-tube 10 having the nozzle is referred to as the nozzle end 11 (see fig. 11), and the other end (i.e., the bent position) of the U-tube 10 is referred to as the tube end 12 (see fig. 5).

Because the U tubes 10 in the first and second processes are arranged at different intervals, that is, the intervals between the adjacent U tubes 10 of the U tubes 10 received by the receiving mechanism 100 are different from the intervals between the U tubes 10 required by the shaping mold 230, the U tubes 10 must be adjusted in pitch before being used for shaping. Specifically, a plurality of material receiving grooves 121 of the material receiving assembly 120 receive a plurality of U tubes 10 in a one-to-one correspondence manner, and the distance between two adjacent material receiving grooves 121 is adjustable, so that the distance between the U tubes 10 is adjusted to meet the requirement of the shaping mold 230 on the distance between the U tubes 10. The feeding assembly 130 slides to the receiving assembly 120, the plurality of spaced U-shaped tubes 10 are handed over from the receiving groove 121 of the receiving assembly 120 to the feeding groove 131 of the feeding assembly 130, then the feeding assembly 130 slides to the bearing platform 220, the plurality of spaced U-shaped tubes 10 are handed over from the feeding groove 131 of the feeding assembly 130 to the first clamping groove 221 of the bearing platform 220, the bearing platform 220 slides to the shaping mold 230, and the shaping mold 230 can directly shape and process the plurality of U-shaped tubes 10.

A plurality of first clamping blocks 135 are arranged at intervals on the supporting plate 134, and a feeding groove 131 is formed between two adjacent first clamping blocks 135. A plurality of first clamping blocks 135 are provided on the support plate 134 to form feeding slots 131 at intervals consistent with the first clamping slots 221 of the loading platform 220, so as to facilitate the transportation of the U-tubes 10 from the feeding assembly 130 to the loading platform 220.

Specifically, the first slider 133 is connected to the end of the support plate 134 far from the carrying platform 220, so that although the first slider 133 slides on the first guide rail 132 mounted on the receiving rack 110, the support plate 134 and the U tube 10 located in the feeding chute 131 can slide on the shaping mechanism 200 to convey the U tube 10 to the carrying platform 220, so that the receiving mechanism 100 and the shaping mechanism 200 can be independent from each other without interference, and the support plate 134 can slide between the receiving mechanism 100 and the shaping mechanism 200 to convey the U tube 10.

Further, referring to fig. 5, the feeding assembly 130 further includes a conveying belt 136 rotatably mounted on the receiving rack 110, a conveying direction of the conveying belt 136 is the same as a sliding direction of the first sliding block 133, and the top of the conveying belt 136 bears the supporting plate 134, so as to avoid insufficient support of the first sliding block 133 on the supporting plate 134.

Further, referring to fig. 4, the bearing platform 220 is arranged on the shaping frame 210 in a liftable manner, and when the feeding assembly 130 slides to one side of the bearing platform 220, the bearing platform 220 is lifted, so that the U-shaped tube 10 is conveyed from the feeding assembly 130 to the bearing platform 220.

The bearing platform 220 and the feeding assembly 130 are staggered, when the feeding assembly 130 slides to the shaping frame 210, the feeding assembly 130 is located on one side of the bearing platform 220, the bearing platform 220 cannot block the feeding assembly 130, then, the bearing platform 220 ascends to bear the suspended part of the U tube 10, the U tube 10 falls in the first clamping groove 221 of the bearing platform 220, the bearing platform 220 continuously ascends, and then the U tube 10 is separated from the feeding groove 131 of the feeding assembly 130, so that the U tube 10 is conveyed to the bearing platform 220 from the feeding assembly 130.

Similarly, the receiving assembly 120 is liftably mounted on the receiving bracket 110, and the feeding assembly 130 is located outside the receiving assembly 120. The receiving assembly 120 ascends to receive the U-tubes 10 and adjust the distance between the U-tubes 10. Then, the feeding assembly 130 slides to one side below the receiving assembly 120, the receiving assembly 120 descends, and the U-shaped tubes 10 with the adjusted spacing descend and fall into the feeding groove 131 of the feeding assembly 130.

Specifically, referring to fig. 5, 8 and 9, the receiving assembly 120 includes a tension driving element 122, a second guide rail 123 and a plurality of receiving portions 125, the tension driving element 122 and the second guide rail 123 are both installed on the receiving bracket 110, the receiving portions 125 have receiving slots 121, the receiving portions 125 are installed on the second guide rail 123 through second sliders 126 in a sliding manner, two adjacent receiving portions 125 are connected through a connecting rod 127 in a sliding manner, the tension driving element 122 is connected with a first receiving portion 125 of the receiving portions 125, so as to drive the first receiving portion 125 to slide along the second guide rail 123.

The tension driving member 122 drives the first material receiving portion 125 to slide, and since two adjacent material receiving portions 125 are connected by the connecting rod 127 in a sliding manner, the material receiving portions 125 are linked with each other. If the first receiving portion 125 slides away from the last receiving portion 125, the receiving portions 125 are mutually dispersed, and the distance between the receiving portions 125 and the receiving grooves 121 is increased. On the contrary, the distances between the receiving parts 125 and the receiving grooves 121 decrease.
