Description

Technical Field

[0001] This utility model relates to the field of air conditioning heat exchanger manufacturing and processing technology, and in particular to an automatic copper tube supply device for the refrigeration industry. Background Technology

[0002] As a core component of air conditioning systems, heat exchangers typically consist of U-shaped copper tubes and fins. Traditionally, before the fins are inserted into the U-shaped copper tubes, workers must coordinate with the production rhythm to retrieve the tubes from the storage area and transport them to the designated work area for insertion. This manual handling results in low production efficiency, high labor intensity, and increased labor costs. Summary of the Invention

[0003] This utility model discloses an automatic copper pipe supply device for the refrigeration industry, which provides a reliable copper pipe supply device to replace manual handling operations, improve production efficiency, and reduce the labor intensity of workers.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] An automatic copper tube supply device for the refrigeration industry includes: a conveyor line and a plurality of clamping modules disposed on the conveyor line;

[0006] The clamping module includes a first clamping member and two second clamping members symmetrically arranged on the first clamping member. The first clamping member and each of the second clamping members can form a clamping groove with an opening, which can clamp a straight section of a U-shaped copper tube.

[0007] The second clamping member is rotatably connected to the first clamping member via a rotating shaft, and an elastic element is provided between the end of the second clamping member away from the opening and the first clamping member;

[0008] The elastic element enables the opening to remain closed after the straight pipe section is inserted into the clamping groove from the opening;

[0009] The clamping module further includes a limiting pin fixed on the first clamping member, the axis of the limiting pin being parallel to the axis of the rotating shaft, the second clamping member having an oblong hole, the limiting pin being located in the oblong hole, and the second clamping member being able to swing relative to the first clamping member through the oblong hole.

[0010] Furthermore, the elastic element is a return spring;

[0011] As the straight pipe section is inserted into the clamping groove from the opening, the end of the second clamping member away from the return spring rotates toward the side away from the first clamping member, the return spring is compressed, and the opening is in the open state;

[0012] After the straight pipe section is inserted into the clamping groove, the reset spring releases its elastic force, keeping the opening closed.

[0013] Furthermore, the first clamping member is provided with a positioning pin, the second clamping member is provided with a positioning groove opposite to the positioning pin, one end of the return spring is sleeved on the positioning pin, and the other end of the return spring is placed in the positioning groove.

[0014] Furthermore, the first clamping member has a first guide slope at the end near the opening, and the second clamping member has a second guide slope at the end near the opening, with the first guide slope and the second guide slope being arranged opposite to each other.

[0015] Furthermore, the clamping module and the conveyor line are detachably connected.

[0016] Furthermore, the conveyor line is a chain conveyor line, and the chain of the conveyor line is provided with chain plates, and each chain plate is provided with two clamping modules.

[0017] Furthermore, positioning mechanisms are symmetrically arranged on the conveyor line;

[0018] The positioning mechanism includes a first cylinder, a mounting plate, and a roller bearing. The first cylinder is fixed on the frame of the conveyor line, and the stroke direction of the first cylinder is horizontal and perpendicular to the conveying direction of the conveyor line. The mounting plate is fixed on the piston rod of the first cylinder, and the roller bearing is mounted on the mounting plate. The axial direction of the roller bearing is vertical and perpendicular to the conveying direction of the conveyor line.

[0019] The chain plate has positioning blocks at both ends, and the positioning blocks have bearing positioning grooves that match the outer ring of the roller bearing.

[0020] Furthermore, the conveyor line is equipped with an alignment device;

[0021] The alignment device includes a second cylinder and a push plate. The second cylinder is fixed on the frame of the conveyor line, and the push plate is fixed on the piston rod of the second cylinder. The stroke direction of the second cylinder is horizontal and perpendicular to the conveying direction of the conveyor line.

[0022] Furthermore, along the conveying direction of the conveyor line, the conveyor line is equipped with multiple matrix fiber optic sensors, which are used to detect whether there is a U-shaped copper tube on the clamping module.

[0023] Beneficial effects:

[0024] This utility model provides an automatic copper tube supply device for the refrigeration industry. By setting a clamping module on the conveyor line, the clamping module can move synchronously with the conveyor line. The clamping module forms two clamping slots with the first clamping member and two second clamping members, which respectively clamp two straight sections of U-shaped copper tube. By setting an elastic member, the opening of the straight section is kept closed after being inserted into the clamping slot, thereby ensuring that the U-shaped copper tube will not fall off the clamping module during the conveying process. This replaces the traditional manual handling method, realizes the automated feeding of copper tubes, and effectively improves production efficiency.

[0025] By setting limit pins and waist-shaped holes, the range of motion of the second clamping member is limited, avoiding excessive deformation of the elastic member, thus ensuring the reliability of the clamping module and improving the reliability of the copper tube supply device.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0042] This embodiment provides an automatic copper pipe supply device for the refrigeration industry chain, such as... Figure 1 and Figure 2 As shown, it includes: a conveyor line 2 and several clamping modules 1 disposed on the conveyor line 2;

[0043] like Figures 5 to 7As shown, the clamping module 1 includes a first clamping member 11 and two second clamping members 12 symmetrically arranged on the first clamping member 11, as follows: Figure 7 As shown, the first clamping member 11 and each of the second clamping members 12 can form a clamping groove 4 with an opening 3, the clamping groove 4 being able to clamp such as Figure 12 The straight section A1 of the U-shaped copper pipe A shown;

[0044] like Figure 7 As shown, the second clamping member 12 is rotatably connected to the first clamping member 11 via a rotating shaft 14, and an elastic member is provided between the end of the second clamping member 12 away from the opening 3 and the first clamping member 11.

[0045] In this embodiment, the rotating shaft 14 is fixed on the second clamping member 12, the first clamping member 11 is provided with a shaft hole for mounting the rotating shaft 14, and shaft clips are provided at both ends of the rotating shaft 14 to limit the axial displacement of the rotating shaft 14.

[0046] The elastic element enables the straight pipe section A1 to be inserted into the clamping groove 4 through the opening 3, and the opening 3 remains closed.

[0047] like Figure 7 As shown, the clamping module 1 further includes a limiting pin 13 fixed on the first clamping member 11, the axis of the limiting pin 13 being parallel to the axis of the rotating shaft 14, as shown. Figure 10 As shown, the second clamping member 12 has a waist-shaped hole 16, and the limiting pin 13 is located in the waist-shaped hole 16. The second clamping member 12 can swing relative to the first clamping member 11 through the waist-shaped hole 16.

[0048] This embodiment provides an automatic copper tube supply device for the refrigeration industry. By setting a clamping module 1 on the conveyor line 2, the clamping module 1 can move synchronously with the conveyor line 2. The clamping module 1 forms two clamping grooves 4 with the first clamping member 11 and the two second clamping members 12, respectively clamping the two straight pipe sections A1 of the U-shaped copper tube A. By setting an elastic element, the opening 3 of the straight pipe section A1 is kept closed after being inserted into the clamping groove 4, thereby ensuring that the U-shaped copper tube A will not fall off the clamping module 1 during the conveying process. This replaces the traditional manual handling method, realizes the automated feeding of copper tubes, and effectively improves production efficiency.

[0049] By setting the limit pin 13 and the waist-shaped hole 16, the range of motion of the second clamping member 12 is limited, so as to avoid excessive deformation of the elastic member and affect the life of the elastic member, thereby ensuring the reliability of the clamping module 1 and improving the reliability of the copper tube supply device.

[0050] In this embodiment, the conveyor line 2 is a chain conveyor line. The conveying speed of the chain conveyor line is adjustable and can be matched with the production cycle, such as... Figure 2 and Figure 4 As shown, the chain of the conveyor line 2 is equipped with chain plates 21. Two clamping modules 1 are fixed to each chain plate 21 by bolts to stably clamp the U-shaped copper tube A. In actual production, since the U-shaped copper tube A is relatively long, it can be fixed to one side of the conveyor line frame 22 as shown in the diagram. Figure 1 and Figure 2 The support frame 5 shown is designed to better support the U-shaped copper tube A.

[0051] In actual production, a robotic arm can be set up in the storage area to grab the U-shaped copper tube A and place it on the clamping module 1 for clamping. After the conveyor line 2 transports the U-shaped copper tube A to the designated working area, the robotic arm set up in the designated working area can grab the U-shaped copper tube A and remove it from the clamping module 1 for the next insertion operation.

[0052] In a specific embodiment, such as Figure 2 As shown, positioning mechanisms 6 are symmetrically arranged on the conveyor line 2;

[0053] like Figure 3 As shown, the positioning mechanism 6 includes a first cylinder 61, a mounting plate 62, and a roller bearing 63. The roller bearing 63 is a bolt-type roller bearing. The first cylinder 61 is fixed on the frame 22 of the conveyor line 2. The stroke direction of the first cylinder 61 is horizontal and perpendicular to the conveying direction of the conveyor line 2. The mounting plate 62 is fixed on the piston rod of the first cylinder 61. The roller bearing 63 is mounted on the mounting plate 62. The axial direction of the roller bearing 63 is vertical and perpendicular to the conveying direction of the conveyor line 2.

[0054] like Figure 4 As shown, the two ends of the chain plate 21 are fixed with positioning blocks 23 by bolts, and the positioning blocks 23 are provided with bearing positioning grooves 24 that match the outer ring of the roller bearing 63;

[0055] When the chain deviates from its proper position, the conveyor line 2 stops conveying and activates the symmetrically arranged first cylinder 61. The first cylinder 61 drives the roller bearing 63 to insert into the bearing positioning groove 24, which in turn drives the chain plate 21 to move, thereby driving the chain to move and thus correcting the position of the chain and achieving deviation correction.

[0056] In a specific embodiment, the conveyor line 2 is provided with an alignment device, such as... Figure 2As shown, the alignment device includes a second cylinder 71 and a push plate 72. The second cylinder 71 is fixed on the frame 22 of the conveyor line 2, and the push plate 72 is fixed on the piston rod of the second cylinder 71. The stroke direction of the second cylinder 71 is horizontal and perpendicular to the conveying direction of the conveyor line 2.

[0057] Along the conveying direction of the conveyor line 2, the conveyor line 2 is provided with a plurality of matrix fiber optic sensors 8, which are used to detect whether there is a U-shaped copper tube A on the clamping module 1;

[0058] In this embodiment, eight U-shaped copper tubes A are grouped together. The conveyor line 2 is equipped with eight matrix fiber optic sensors 8. When the eight matrix fiber optic sensors 8 detect eight U-shaped copper tubes A, the conveyor line 2 stops conveying. The second cylinder 71 drives the push plate 72 to move, and the push plate 72 pushes the ends of the eight U-shaped copper tubes A together, so that the entire group of U-shaped copper tubes A can be uniformly grasped by the robot arm.

[0059] In a specific embodiment, such as Figure 7 As shown, the elastic element is a return spring 15;

[0060] During the process of the straight pipe section A1 being inserted into the clamping groove 4 from the opening 3, the second clamping member 12 is squeezed by the straight pipe section A1, causing the end of the second clamping member 12 away from the return spring 15 to rotate toward the side away from the first clamping member 11, the return spring 15 is compressed, and the opening 3 is in the open state.

[0061] After the straight pipe section A1 is inserted into the clamping groove 4, the reset spring 15 releases its elastic force, keeping the opening 3 in a closed state.

[0062] In a specific embodiment, such as Figure 7 As shown, the first clamping member 11 is provided with a positioning pin 17, the second clamping member 12 is provided with a positioning groove 18 opposite to the positioning pin 17, one end of the return spring 15 is sleeved on the positioning pin 17, and the other end of the return spring 15 is placed in the positioning groove 18.

[0063] The positioning pin 17 and positioning groove 18 provide a mounting base for the return spring 15, ensuring that the return spring 15 can effectively release its elastic force.

[0064] In a specific embodiment, such as Figure 8 and Figure 9 As shown, the first clamping member 11 has a first guide slope 111 at one end near the opening 3, such as... Figure 10 and Figure 11 As shown, the second clamping member 12 has a second guide slope 121 at one end near the opening 3, and the first guide slope 111 and the second guide slope 121 are arranged opposite to each other;

[0065] The first guide slope 111 and the second guide slope 121, which are set opposite to each other, can guide the straight pipe section A1 into the opening 3, ensuring that the straight pipe section A1 is smoothly inserted into the clamping groove 4.

[0066] In a specific embodiment, the clamping module 1 and the conveyor line 2 are detachably connected. In this embodiment, the clamping module 1 is fixed to the chain plate 21 of the conveyor line 2 by bolts.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
