Description

[0002] Heat exchange pipes are widely used in refrigerators, air conditioners and other refrigeration appliances. High-temperature fluids and low-temperature fluids flow through different pipes, and heat is transferred between them through the pipe walls. In order to achieve better heat conduction between pipes, two pipes are usually welded in parallel to form a parallel pipe body, and then bent into a parallel coil.

[0003] The common welding method for existing heat exchange pipes is tin soldering, which covers the molten tin liquid in the gap between two parallel pipe bodies, which fixes and increases the heat exchange area. However, in the actual processing process, since the pipe body is relatively slender, a larger gap distance is likely to appear between the parallel pipe bodies during transportation and welding, thereby reducing the stability of welding quality. It is necessary to constantly observe and adjust the pipe body during transportation, which also affects the progress and efficiency of the welding work. Summary of the invention

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] See also Figure 1-5 The embodiment of the present invention provides a parallel coil intelligent welding conveying device, comprising a base platform 1, a welding area on the base platform 1 is provided with a linearly distributed conveying mechanism, and the conveying mechanism comprises:

[0029] The path component 2 comprises a long frame 2.1 crossing the welding area, wherein two parallel partition layers 2.2 are arranged in the long frame 2.1, each partition layer 2.2 is composed of a plurality of rotating rollers 2.3 arranged in parallel, and a transmission channel is formed between the two partition layers 2.2 and the side wall of the long frame 2.1;

[0030] The driving assembly 3 includes a plurality of clamping wheel groups distributed along the length direction of the long strip frame 2.1, each clamping wheel group includes two first driving wheels 3.2 and second driving wheels 3.3 distributed on both sides of the transmission channel, and the first driving wheels 3.2 and the second driving wheels 3.3 can drive the parallel pipes in the transmission channel to move through the welding area when rotating;

[0031] Specifically, the top surface of the base 1 is parallel to the horizontal plane, and a soldering device 14 is installed on the top of the base 1. The soldering device 14 is an existing device and will not be described in detail. The orthographic projection area of ​​the soldering device 14 on the top surface of the base 1 is the welding area. The frame mouth surface of the long frame 2.1 is parallel to the horizontal plane. The axis of each rotating roller 2.3 is perpendicular to the length direction line of the long frame 2.1. The partition layer 2.2 is provided with an open space aligned with the welding area, so that the welding equipment on the base 1 can weld the parallel pipes on the transmission channel. After welding, the parallel pipes become parallel pipes. The wheel plate plane of the first driving wheel 3.2 is parallel to the horizontal plane. The side of the long frame 2.1 is provided with a side opening for the first driving wheel 3.2 and the second driving wheel 3.3 to extend into;

[0032] In actual use, the parallel pipes are extended into the transmission channel formed between the two partition layers 2.2 and the side walls of the long frame 2.1. At this time, the first driving wheels 3.2 located on both sides of the transmission channel apply a clamping force in the horizontal direction to the parallel pipes, so that there is a horizontal squeezing force between the two parallel pipes, thereby keeping the two parallel pipes in a clamping and squeezing state. At the same time, each rotating first driving wheel 3.2 causes the pipes in the transmission channel to move axially, and the gap spacing between the parallel pipe bodies is controlled, so that the gap between the two parallel pipes is welded through the welding area in turn to form a parallel pipe, which is beneficial to improving the stability of welding quality and the progress efficiency of welding work.

[0033] In another embodiment provided by the present invention, both ends of the frame of the long frame 2.1 are provided with plug ports 2.4 corresponding to the cross-sectional contour lines of the parallel pipes, and the parallel pipes are inserted into the transmission channel through the plug port 2.4 at one end of the long frame 2.1, and the parallel pipes after welding are extended from the inside of the transmission channel through the plug port 2.4;

[0034] In another embodiment provided by the present invention, the rotating roller 2.3 includes a roller shaft 2.31, a support tube 2.32 is coaxially fixed on the roller shaft 2.31, a step structure is formed between the circumferential surface of the support tube 2.32 and the circumferential surface of the roller shaft 2.31, and the support tube 2.32 can move axially on the roller shaft 2.31;

[0035] The support tube 2.32 includes a telescopic tube 2.321, which is formed by a plurality of tube bodies being sleeved and stacked in sequence, and its structure is similar to the structure of a signal telescopic antenna pole or a handle of a telescopic umbrella. A clamping piece 2.322 capable of limiting the telescopic tube 2.321 is fixed on the roller shaft 2.31, and the clamping piece 2.322 includes a parallel block 9 parallel to the axis of the roller shaft 2.31, one end of the parallel block 9 is fixed to the roller shaft 2.31 through a connecting block 10, a screw rod 11 is spirally penetrated through the parallel block 9, one end of the screw rod 11 is fixed with a squeezing block 12 capable of squeezing the telescopic tube 2.321, and the other end of the screw rod 11 is fixed with a knob block 13, and the axis of the screw 11 is perpendicular to the axis of the roller shaft 2.31;

[0036] In actual use, the diameters of two parallel pipes usually have a certain diameter difference. For example, the diameter of the pipe with a higher temperature is 1 / 3A, and the diameter of the other pipe with a lower temperature is usually A. Therefore, when arranged in parallel, the pipe with a smaller diameter is in contact with the support pipe 2.32, and the stacking thickness of the telescopic pipe 2.321 can be adjusted according to the actual diameter of the pipe with a smaller diameter. Under the support of the support pipe 2.32, the centers of the two pipes with different diameters are all on the same plane. Then, the screw rod 14 is twisted by the knob block 13 so that the pushing block 15 applies pressure to the side of the telescopic pipe 2.321, so that the pipe walls of the stacked telescopic pipes 2.321 are tightly squeezed against each other, thereby limiting the telescopic direction of the telescopic pipe 2.321, so that the rotating roller 2.3 can make corresponding adjustments according to the actual diameter difference between the two parallel pipes, so that the centers of the two pipes with different diameters are all on the same plane, which is more flexible and easy to operate.

[0037] In another embodiment provided by the present invention, the first driving wheel 3.2 and the second driving wheel 3.3 are of the same structure, the first driving wheel 3.2 includes a wheel body 3.21, the wheel surface of the wheel body 3.21 is parallel to the horizontal direction, a driving shaft 3.22 is rotatably penetrated through the middle of the wheel body 3.21, the axis of the driving shaft 3.22 coincides with the axis of the wheel body 3.21, and the driving shaft 3.22 can provide driving force for the rotation of the wheel body 3.21 through the transmission assembly 4, wherein the start and stop of the driving shaft 3.22 is in a synchronous state with the start and stop of the welding equipment on the base platform 1;

[0038] It should be further explained that the welding equipment on the base 1 is to melt the tin wire to form tin liquid, fill the gap along the parallel movement, and then cool and solidify it with cooling water to complete the soldering process. Therefore, when the soldering of a section of parallel tubes is completed, it is necessary to stop the flow of tin liquid, that is, to suspend soldering. Before the parallel tubes of the next section are inserted into the transmission channel formed by the two partition layers 2.2 and the side walls of the long frame 2.1, the wheel body 3.21 needs to be in a stopped state. During the process of inserting the parallel tubes of the next section into the transmission channel, when the welding starting position on the parallel tubes is aligned with the welding area, the soldering process can be started and the wheel body 3.21 is restored to the running state.

[0039] The wheel body 3.21 has a disc-shaped cavity 3.23 formed inside, the axis of the disc-shaped cavity 3.23 coincides with the axis of the wheel body 3.21, the wheel body 3.21 has an annular groove 3.24 formed on its circumferential surface, the center of which is located on the axis of the wheel body 3.21, an airbag ring 3.25 is fitted and fixed in the annular groove 3.24, the airbag ring 3.25 is a ring-shaped structure made of elastic rubber material, the airbag ring 3.25 is in an expanded state when inflated, and in a contracted state when deflated;

[0040] Further, the transmission assembly 4 includes a plurality of arc-shaped cylinders 4.1 which are fixedly distributed in an annular shape in the disc-shaped cavity 3.23, the center of the arc-shaped cylinder 4.1 is located on the axis of the driving shaft 3.22, the bottom of the arc-shaped cylinder 4.1 is connected to the airbag ring 3.25 through the air guide unit 4.2, a piston block 4.3 is adapted to be arranged in the arc-shaped cylinder 4.1, preferably, the arc-shaped cylinder 4.1 and the piston block 4.3 are connected through a spring 4.6, an arc-shaped rod 4.4 with one end extending out of the arc-shaped cylinder 4.1 is fixed on the piston block 4.3, the center of the arc-shaped rod 4.4 is located on the axis of the driving shaft 3.22, one end of the arc-shaped rod 4.4 is fixed to the driving shaft 3.22 through a cross bar 4.5, the length direction line of the cross bar 4.5 is parallel to the horizontal plane, and the length direction line of the cross bar 4.5 is perpendicular to the axis of the driving shaft 3.22;

[0041] It should be particularly noted that the air guide unit 4.2 includes a hard tube 4.21 fixedly passing through the wall of the disc-shaped cavity 3.23, one end of the hard tube 4.21 is flush with the wall surface of the annular groove 3.24, the other end side of the hard tube 4.21 is fixed to the bottom of the arc-shaped cylinder 4.1, the extension line of the axis of the hard tube 4.21 is perpendicular to the axis of the drive shaft 3.22, the tube body of the hard tube 4.21 located in the disc-shaped cavity 3.23 is fixed to the inner wall of the disc-shaped cavity 3.23, a slider 4.22 is adapted in the tube body of the hard tube 4.21, a first elastic rubber tube 4.23 is fixedly passed through the middle of the slider 4.22, and one end of the first elastic rubber tube 4.23 is fixedly passed through the hard tube 4.21 and is connected to the bottom of the arc-shaped cylinder 4.1;

[0042] A baffle plate 4.24 is fixed on one end of the hard tube 4.21 communicating with the annular groove 3.24, and the baffle plate 4.24 can completely seal and block the hard tube 4.21. A second elastic rubber tube 4.25 communicating with the airbag ring 3.25 is fixedly passed through the baffle plate 4.24, and one end of the second elastic rubber tube 4.25 away from the airbag ring 3.25 is connected to the first elastic rubber tube 4.23, and the first elastic rubber tube 4.23 and the second elastic rubber tube 4.25 are connected to form an air guide channel;

[0043] When the actual wheel body 3.21 returns to the running state, the driving shaft 3.22 drives the wheel body 3.21 to rotate through the transmission assembly 4. Specifically, when the driving shaft 3.22 rotates, the piston block 4.3 moves toward the bottom of the arc tube 4.1 through the cross bar 4.5 and the arc rod 4.4, and the spring 4.6 is compressed and deformed. The air in the arc tube 4.1 enters the airbag ring 3.25 through the air guide unit 4.2. Specifically, the air in the arc tube 4.1 enters the airbag ring 3.25 through the first elastic rubber tube 4.23 and the second elastic rubber tube 4.25, so that the airbag ring 3.25 is inflated, thereby clamping the parallel tube bodies and increasing the friction force of driving the tube bodies until the piston block 4.3 contacts the bottom of the arc tube 4.1, thereby transmitting the driving force of the driving shaft 3.22 to the wheel body 3.21. At this time, the wheel body 3.21 receives the driving shaft 3.22 and rotates synchronously;

[0044] As the rotation speed of the wheel body 3.21 increases, the slider 4.22 moves along the hard tube 4.21 under the action of centrifugal force, so that the first elastic rubber tube 4.23 is elastically deformed to be elongated, and at the same time, the first elastic rubber tube 4.23 and the second elastic rubber tube 4.25 located between the slider 4.22 and the baffle 4.24 are squeezed by the slider 4.22 and bent and deformed, so that the air guide channel is in a closed state, which is conducive to keeping the airbag ring 3.25 in an expanded state, thereby achieving the effect of clamping and fitting with the tube body;

[0045] When the wheel body 3.21 is in a stopped state, the centrifugal force disappears at this time. Therefore, under the action of the elastic restoring force of the first elastic rubber tube 4.23, the slider 4.22 returns to its initial position, the first elastic rubber tube 4.23 returns to its natural state, and the first elastic rubber tube 4.23 and the second elastic rubber tube 4.25 between the slider 4.22 and the baffle 4.24 are no longer folded and restored to conduction, that is, the air guide channel is restored to a conducting state. At this time, under the action of the elastic restoring force of the airbag ring 3.25 itself, or under the elastic restoring force of the spring 4.6, the piston block 4.3 is restored to the tube mouth position of the arc tube 4.1. At this time, the gas in the airbag ring 3.25 is restored to the arc tube 4.1, and the airbag ring 3.25 is switched from an expanded state in which a clamping force is applied to the tube body to a contracted state, thereby facilitating the insertion of the parallel tubes until the welding starting position on the parallel tubes is aligned with the welding area, and then the wheel body 3.21 can be started to be restored to a running state.

[0046] In another embodiment provided by the present invention, an annular separation membrane 5 is fixed on the inner ring wall of the airbag ring 3.25, and a receiving cavity 6 is formed between the annular separation membrane 5 and the circumferential inner wall surface of the outer ring of the airbag ring 3.25. A plurality of evenly distributed separation membranes 7 are arranged in the cavity of the receiving cavity 6, and the space formed between each separation membrane 7 is filled with flowing particles 8;

[0047] In actual use, as the rotation speed of the wheel body 3.21 increases, the flowing particles 11 will also provide moving squeezing force to the pipe under the action of centrifugal force, thereby improving the clamping effect.

[0048] A production line is provided with the above-mentioned conveying equipment for intelligent welding of parallel coils, which can convey parallel pipe bodies through a welding area so that the parallel pipe bodies are converted into parallel pipe bodies, wherein there is a sufficient spacing between the two first driving wheels 3.2 for the parallel pipe bodies to move in a transmission channel, and when the parallel pipe bodies reach a starting welding position, the two first driving wheels 3.2 automatically clamp the parallel pipe bodies transversely, and then the first driving wheels 3.2 convey the parallel pipe bodies through the welding area in sequence until the parallel pipe bodies in this section are completely formed into parallel pipe bodies, that is, when the entire wheel body 3.21 returns to the operating state, the pipe bodies are first clamped, and then they start to rotate to realize the axial drive of the pipe bodies, and the airbag ring 3.25 is kept in an expanded state by the air guide unit 4.2, thereby maintaining stability during drive and conveying.

[0049] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
