[0002] like Figure 1 The copper tube shown is used for welding, and its core function is as a key heat-conducting component in the heat exchange system.

[0003] However, existing copper tube feeding devices have the following defects in actual production: 1. The existing horizontal conveying mechanism for copper tubes uses a chain for linear conveying, which often results in copper tube misalignment during the conveying process, failing to meet subsequent positioning requirements. Furthermore, using a chain to convey copper tubes has led to scratches of varying sizes appearing on the surface of the copper tubes, affecting the product's appearance quality; 2. The existing feeding device cannot automatically detect the orientation of the copper tubes, requiring manual judgment and flipping, increasing the number of processes and uncertainties. Therefore, it is necessary to improve upon the defects of the existing technology. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, this utility model provides an automatic copper tube feeding device for welding, which realizes unmanned operation of the entire process from batch feeding, orderly conveying, precise positioning, intelligent reversal to directional output of copper tubes.

[0008] A material blocking mechanism, a limiting mechanism, and a material pushing mechanism are arranged along the conveying direction of the horizontal conveying mechanism, and the limiting mechanism and the material pushing mechanism are arranged perpendicular to the conveying direction of the horizontal conveying mechanism.

[0009] The unloading mechanism is installed on the side of the horizontal conveying mechanism away from the pushing mechanism. The unloading mechanism includes an unloading frame with a guide groove and an unloading plate installed at the first end of the unloading frame and extending to the horizontal conveying mechanism. A reversing mechanism is arranged at the lower end of the unloading plate. The reversing mechanism has a reversing disk extending to the unloading plate, which can drive the copper sleeve on the reversing disk to change direction by 180°.

[0010] In a preferred embodiment of the present invention, the horizontal conveying mechanism includes a conveying frame mounted on a base, a plurality of conveying rollers rotatably mounted on the conveying frame, and a conveyor belt wound around the conveying rollers, wherein the conveyor belt is made of rubber.

The telescopic end of the limiting cylinder extends into the conveyor frame and is connected to a limiting block. The limiting block is driven by the limiting cylinder to move closer to or away from the copper tube, thereby limiting the lateral displacement of the copper tube.

[0014] In a preferred embodiment of the present invention, the pushing mechanism includes a pushing cylinder installed on one side of the conveyor frame. The telescopic end of the pushing cylinder extends into the conveyor frame and is connected to a pushing plate.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] like Figure 2-4 As shown, an automatic feeding device for welding copper pipes includes a base 1, and a horizontal conveying mechanism 2 is provided on the top of the base 1.

[0041] The feeding mechanism 3 is located on the base 1 and includes a feeding component 31, a feeding hopper 32 and a drive component 33. The feeding hopper 32 is connected to the feeding component 31 to form a hopper. The drive component 33 is connected to the feeding component 31 and is used to drive the feeding component 31 to move up and down to drive the copper pipe in the hopper to be conveyed upward to the horizontal conveying mechanism 2 step by step.

[0042] A material blocking mechanism 4, a limiting mechanism 5, and a pushing mechanism 6 are arranged along the conveying direction of the horizontal conveying mechanism 2. The limiting mechanism 5 and the pushing mechanism 6 are arranged perpendicular to the conveying direction of the horizontal conveying mechanism 2.

[0043] The unloading mechanism 7 is installed on the side of the horizontal conveying mechanism 2 away from the pushing mechanism 6. The unloading mechanism 7 includes an unloading frame 71 with a guide groove and an unloading plate 72 installed at the head end of the unloading frame 71 and extending to the horizontal conveying mechanism 2. A reversing mechanism 8 is arranged at the lower end of the unloading plate 72. The reversing mechanism 8 has a reversing disk 81 extending to the unloading plate 72, which can drive the copper sleeve on the reversing disk 81 to change direction by 180°.

[0044] The working principle and beneficial effects of the above embodiments are as follows:

[0045] This utility model provides an automatic copper tube feeding device for welding. The operator puts copper tubes into the hopper in batches, and the drive component 33 starts to lift the copper tubes from the bottom of the hopper step by step until they are conveyed to the horizontal conveying mechanism 2.

[0046] The copper tubes enter the horizontal conveying mechanism 2 and are conveyed forward one by one. The blocking mechanism 4 initially screens and removes copper tubes with unqualified postures to ensure that only one copper tube is released at a time. The copper tubes are conveyed to the limiting mechanism 5, which is used to accurately position the copper tubes and ensure the operation of the pushing mechanism 6.

[0047] After the copper tube is positioned at the limiting mechanism 5, the pushing mechanism 6 is activated, which smoothly pushes the copper tube through the unloading plate 72 to the reversing plate 81 in a direction perpendicular to its own axis. The direction of the copper tube is adjusted as needed. The next pushing action pushes the copper tube previously placed on the reversing plate 81 to slide into the guide groove of the unloading rack 71, completing the unloading action of the copper tube.

[0048] This utility model achieves continuous and stable feeding by requiring no manual intervention throughout the entire process from batch feeding to directional output. The coordinated operation of the limiting mechanism 5 and the reversing mechanism 8 ensures the positioning accuracy and orientation consistency of the copper tubes.

[0049] In one embodiment,

[0050] like Figure 5 As shown, the above-mentioned horizontal conveying mechanism 2 includes a conveying frame 21 mounted on the base 1, a plurality of conveying rollers 22 rotatably mounted on the conveying frame 21, and a conveyor belt 23 wound around the conveying rollers 22. The conveyor belt 23 is made of rubber.

[0051] Two conveying tracks are provided on the conveying roller 22, and a conveyor belt 23 is installed in each of the two conveying tracks. The cross-section of the conveyor belt 23 is circular, and a bearing cavity for bearing the copper sleeve is formed between the two conveyor belts 23.

[0052] Two circular conveyor belts 23 are installed in two parallel tracks to form a bearing cavity for the copper sleeve. The copper tube is placed in the bearing cavity and will not shift left or right or roll, thus achieving stable centering and conveying. The rubber conveyor belts 23 provide a certain degree of protection for the copper tube and prevent hard contact from damaging the surface of the copper tube.

[0053] In one embodiment,

[0054] The aforementioned material blocking mechanism 4 includes a guide plate 41 mounted on the conveyor frame 21 and a guide frame 42 mounted on the opposite side of the conveyor frame 21 and arranged facing the guide plate 41. The end of the guide frame 42 extends into the aforementioned hopper, and the guide plate 41 has an inclined guide surface facing the guide frame 42.

[0055] The guide plate 41 is designed with an inclined guide surface facing the guide frame 42. Copper pipes with non-compliant postures are blocked by the guide plate 41 and guided along its guide surface to fall into the guide frame 42, and finally slide into the hopper for reloading.

[0056] In one embodiment,

[0057] The aforementioned limiting mechanism 5 includes a limiting cylinder 51 installed on one side of the conveyor frame 21. The telescopic end of the limiting cylinder 51 extends into the conveyor frame 21 and is connected to a limiting block 52. The limiting block 52 is driven by the limiting cylinder 51 to move closer to or away from the copper tube, thereby limiting the lateral displacement of the copper tube.

[0058] When the pushing mechanism 6 needs to push the copper tube, the limiting cylinder 51 pushes the limiting block 52 to axially limit the adjacent copper tube, so as to avoid the continuous displacement of the copper tube affecting the action of the pushing mechanism 6 and ensure the stability of the action of the pushing mechanism 6.

[0059] In one embodiment,

[0060] like Figure 6 As shown, the above-mentioned pushing mechanism 6 includes a pushing cylinder 61 installed on one side of the conveyor frame 21. The telescopic end of the pushing cylinder 61 extends into the conveyor frame 21 and is connected to a pushing plate 62. An L-shaped limiting plate 63 is connected to the pushing plate 62. The L-shaped limiting plate 63 is placed at the conveying end of the horizontal conveying mechanism 2.

[0061] A first photoelectric switch 64 is installed on the L-shaped limiting plate 63 facing the copper tube, and a second photoelectric switch 65 is provided perpendicular to the first photoelectric switch 64 on one side of the conveyor frame 21.

[0062] The second photoelectric switch 65 is used to detect whether the lateral displacement of the copper tube is in place. If the copper tube is in place, that is, one end of the copper tube contacts the L-shaped limit plate 63, the second photoelectric switch 65 sends an electrical signal and feeds it back to the limit mechanism 5. The limit cylinder 51 drives the limit block 52 to abut against the copper tube connected to it, so as to prevent the copper tube that is continuously conveyed after the pushing mechanism 6 pushes the material and continues to move forward.

[0063] The first photoelectric switch 64 is used to detect the placement position of the large and small ends of the copper tube. When the small end size of the copper tube is detected, the pusher plate 62 pushes the copper tube onto the reversing disk 81, driving the reversing disk 81 to rotate the copper sleeve 180°. During the displacement of the copper sleeve, the L-shaped limiting plate 63 moves synchronously with the pusher plate 62 to restrict the copper tube from the side, preventing the copper tube from tilting or deviating during the pushing process, and ensuring that it falls accurately into the reversing disk 81.

[0064] Specifically, the copper tube is conveyed to the end of the conveyor frame 21, with one end contacting the L-shaped limiting plate 63. The second photoelectric switch 65 detects the arrival signal and feeds it back to the limiting mechanism 5. The limiting block 52 extends to block the subsequent copper tube. The first photoelectric switch 64 detects the dimensions of both ends of the copper tube to determine whether the smaller end is facing forward. The pushing cylinder 61 drives the pushing plate 62 forward, and the L-shaped limiting plate 63 moves synchronously to stabilize the copper tube from the side and accurately push it to the reversing plate 81. If the first photoelectric switch 64 detects that the smaller end is facing forward, the reversing mechanism 8 drives the reversing plate 81 to rotate 180° to complete the copper tube orientation correction. If the orientation is correct, it is pushed onto the reversing plate 81 and waits for the next copper tube to push it into the guide groove of the unloading frame 71 for unloading.

[0065] In one embodiment,

[0066] like Figure 7 As shown, the reversing mechanism 8 includes a reversing frame 82 installed on one side of the conveyor frame 21, a lifting cylinder 83 vertically installed on the reversing frame 82, and a reversing cylinder 84 installed at the extension end of the lifting cylinder 83. The reversing plate 81 is installed at the output end of the reversing cylinder 84.

[0067] The feed plate 72 has a through hole through which the reversing disc 81 passes, and the reversing disc 81 has an arc-shaped positioning groove for a copper sleeve, which extends to the feed plate 72.

[0068] In the initial state, the lifting cylinder 83 is in the retracted state, and the upper surface of the reversing plate 81 is basically flat with the upper surface of the unloading plate 72. The copper tube pushed from the pushing mechanism slides along the unloading plate 72 into the arc-shaped positioning groove of the reversing plate 81 to complete the initial positioning.

[0069] When the first photoelectric switch 64 detects that the copper tube needs to be reversed, the piston rod of the lifting cylinder 83 extends, lifting the reversing cylinder 84 and the reversing plate 81 upward. At this time, the copper tube is completely lifted and separated from the support surface of the feeding plate 72. The output shaft of the reversing cylinder 84 rotates 180°, driving the copper tube to rotate synchronously and completing its direction correction. After the rotation action is completed, the lifting cylinder 83 acts again, the piston rod retracts, and the reversing plate 81 and the copper tube descend together, returning to the initial position of the reversing plate 81.

[0070] Through the coordinated action of the lifting cylinder 83 and the reversing cylinder 84, as well as the design of the arc-shaped positioning groove on the reversing plate 81, the copper tube is ensured to be stable in position during the reversing process, and will not slip or deviate, thus ensuring the positional accuracy before and after the reversing.

[0071] In one embodiment,

[0072] Guide strips 73 are installed on the feed plates 72 on both sides of the aforementioned reversing disc 81. The guide strips 73 form a guide structure with a large opening and a small middle, which plays a guiding role. The end of the guide strips 73 extends to the feed rack 71.

[0073] In summary:

[0074] This utility model discloses an automatic copper tube feeding device for welding, which realizes unmanned operation of the entire process from batch feeding, orderly conveying, precise positioning, intelligent reversal to directional output of copper tubes, greatly reducing reliance on manual labor and labor intensity.

[0075] This invention uses a first photoelectric switch to detect the size of the copper tube and automatically determine whether a reversal is needed, thus achieving flexible production. A second photoelectric switch enables precise coordination between the pushing mechanism and the limiting mechanism, avoiding motion interference and improving the overall efficiency and reliability of the device.

[0076] The horizontal conveying mechanism designed in this utility model has two circular conveyor belts installed in two parallel tracks to form a bearing cavity for the copper sleeve, which realizes stable centering and conveying of the copper tube, while avoiding hard contact that could damage the surface of the copper tube.
