Description

Technical Field

[0001] This utility model relates to the field of welding torch nozzle production technology, and more specifically, to a copper tube sorting and testing device. Background Technology

[0002] Spring clip assembly is a crucial step in nozzle manufacturing, involving the precise assembly of copper tubes and spring clips to ensure the product meets process requirements and performance specifications. Traditional spring clip assembly relies primarily on manual operation, which is slow, inefficient, and unsuitable for large-scale production. While automation technology has led to the introduction of some automated assembly equipment, existing equipment still has limitations. Because copper tubes need to be distinguished between their beginning and end, and spring clips are inserted from the end, traditional vibratory feeder systems, although capable of feeding individual copper tubes, lack precise directional sorting capabilities, failing to ensure consistency in the direction of the tubes. This limits the efficiency of subsequent assembly processes. Utility Model Content

[0029] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Example

[0031] The present invention will now be further described with reference to the accompanying drawings.

[0032] like Figures 1 to 3 As shown, the copper tube sorting and detection device provided in this embodiment includes a mounting base 10, a copper tube feeding channel 11, a copper tube sorting carrier 12 and a machine vision component 13 installed on the mounting base 10. The copper tube sorting carrier 12 is located near the discharge end of the copper tube feeding channel 11, and the machine vision component 13 is used to collect image information of the copper tubes in the copper tube sorting carrier 12.

[0033] The working principle and beneficial effects of the above technical solution are as follows:

[0034] This utility model discloses a copper tube sorting and detection device. A copper tube feeding vibratory feeder sends individual copper tubes into the copper tube feeding channel 11. After each copper tube falls into the copper tube sorting carrier 12, the machine vision component 13 collects image information of the copper tubes in the copper tube sorting carrier 12 to determine the head and tail orientation of the copper tubes in the copper tube sorting carrier 12. If the orientation is inconsistent, a robotic arm grasps the copper tubes and adjusts the head and tail orientation during the handling process. This utility model provides a copper tube sorting and detection device for sorting copper tubes by their head and tail orientation to ensure consistency in the head and tail orientation.

[0035] In one embodiment, a copper tube rotary cylinder 14 is installed on a copper tube feeding channel 11, and a discharge roller is located at the discharge end of the copper tube feeding channel 11 for discharging a single copper tube. The discharge roller is installed at the actuating end of the copper tube rotary cylinder 14.

[0036] The working principle and beneficial effects of the above technical solution are as follows:

[0037] The copper tube feeding vibratory feeder feeds individual copper tubes into the copper tube feeding channel 11. The copper tubes are temporarily located in the copper tube feeding channel 11. The copper tubes closest to the discharge end of the copper tube feeding channel 11 rest on the discharge roller. Then, the copper tube rotary cylinder 14 installed on the copper tube feeding channel 11 works, thereby driving the discharge roller located at the discharge end of the copper tube feeding channel 11 to rotate. This drives the copper tubes that are attached to the discharge roller to rotate at a low speed. After the discharge roller stops rotating, the copper tubes automatically roll out from the discharge end of the copper tube feeding channel 11 and fall into the copper tube sorting carrier 12.

[0038] In one embodiment, the copper tube sorting carrier 12 includes:

[0039] The carrier base is mounted on the mounting base 10, and the top of the carrier base is formed with a cavity for accommodating the copper tube.

[0040] Sorting limit cylinder 15, the sorting limit cylinder 15 is installed on the mounting base 10;

[0041] Limiting block 16 is installed on the actuating end of sorting limiting cylinder 15, and the limiting block 16 is adapted to the head end of the copper tube.

[0042] The working principle and beneficial effects of the above technical solution are as follows:

[0043] The copper tube automatically rolls out from the discharge end of the copper tube feeding channel 11 and falls into the cavity located at the top of the carrier base. The sorting and limiting cylinder 15 works, thereby driving the limiting block 16 to abut against the copper tube in the cavity, thereby limiting the copper tube in the cavity so that the machine vision component 13 can collect image information of the copper tube in the cavity.

[0044] In one embodiment, the machine vision component 13 includes:

[0045] The longitudinal movement track 17 is fixedly installed on the mounting base 10;

[0046] The longitudinal sliding block 18 is slidably mounted on the longitudinal sliding rail 17.

[0047] Pneumatic lifting frame 19 is mounted on longitudinal sliding block 18;

[0048] Industrial camera 20 is mounted on pneumatic lifting frame 19 and is used to collect image information of copper tubes in copper tube sorting carrier 12.

[0049] The working principle and beneficial effects of the above technical solution are as follows:

[0050] The copper tube automatically rolls out from the discharge end of the copper tube feeding channel 11 and falls into the cavity located at the top of the carrier base. The limiting block 16 abuts against the copper tube in the cavity, thereby limiting the copper tube in the cavity. Then, the longitudinal sliding block 18 works, thereby driving the pneumatic lifting frame 19 and the industrial camera 20 mounted on the pneumatic lifting frame 19 to move along the longitudinal track 17 towards the cavity. The industrial camera 20 collects image information of the copper tube in the cavity, and the PLC analyzes the image to determine the direction of the copper tube. If the direction is incorrect, the robot arm will adjust the direction of the copper tube during the handling process. It only needs to rotate 180° and swap the head and tail to ensure the consistency of the head and tail direction. The industrial camera 20 collects image information and the PLC analyzes the image. It is a mature vision inspection technology, which will not be described in detail here.

[0051] In one embodiment, the machine vision component 13 further includes:

[0052] Lower mounting base 21 is mounted on mounting base 10;

[0053] Drive motor 22 is mounted on lower mounting base 21;

[0054] Cam 23 is mounted on the actuating end of drive motor 22;

[0055] Top block 24 is mounted on the top of longitudinal slide block 18 via side adjustment bracket 25, and cam 23 abuts against top block 24;

[0056] The return spring rod is connected between the longitudinal slide block 18 and the lower mounting base 21.

[0057] The working principle and beneficial effects of the above technical solution are as follows:

[0058] Copper tubes in the copper tube feeding channel 11 roll into the copper tube sorting carrier 12. The drive motor 22 mounted on the lower mounting base 21 works, thereby driving the cam 23 mounted on the actuating end of the drive motor 22 to rotate. The large radius end of the cam 23 abuts against the top block 24, thereby driving the side adjustment frame 25 connected to the top block 24 and the longitudinal slide block 18 connected to the side adjustment frame 25 to slide along the longitudinal track 17 in the extension direction of the reset spring rod. When the large radius end of the cam 23 is released from abutting against the top block 24, under the reset of the reset spring rod, the longitudinal slide block 18 slides towards the lower mounting base 21.

[0059] In one embodiment, an observation port 26 is provided at the top of the copper tube feeding channel 11.

[0060] The beneficial effects of the above technical solution are as follows:

[0061] The observation port 26 is designed to facilitate observation of the copper tubes inside the copper tube feeding channel 11.

[0062] In one embodiment, the top block 24 is arranged in a circular shape and rotatably mounted on the side adjustment bracket 25. The side adjustment bracket 25 has two screw holes 1 arranged side by side at the end away from the top block 24. The adjustment screw 27 is installed in the screw hole 1. The longitudinal slide block 18 has at least three sets of screw holes 28. Each set of screw holes 28 consists of two screw holes 28 and is adapted to the adjustment screw 27.

[0063] The working principle and beneficial effects of the above technical solution are as follows:

[0064] The top block 24 is mounted on the side adjustment bracket 25, which is detachably mounted on the longitudinal slide block 18 through the cooperation of the adjustment screw 27. The screw hole 28 is provided in three sets to facilitate the adjustment of the installation position of the side adjustment bracket 25 on the longitudinal slide block 18, thereby facilitating the adjustment of the lateral distance between the top block 24 and the cam 23. Specifically, the shorter the lateral distance between the top block 24 and the cam 23, the longer the lateral movement distance of the longitudinal slide block 18, and the longer the lateral distance between the top block 24 and the cam 23, the shorter the lateral movement distance of the longitudinal slide block 18. In this way, the position of the industrial camera 20 can be adjusted for copper tubes of different lengths and models to facilitate the acquisition of image information of the copper tubes in the cavity.

[0065] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
