Description

Technical Field

[0001] The utility model relates to the field of pipe fitting processing equipment, in particular to a positioning mechanism for installing partitions. Background Art

[0002] Flute-shaped pipes are usually used for the connection of air-conditioning pipelines. Due to their many openings, their processing technology is relatively cumbersome. In addition, partitions and filter meshes need to be installed inside the flute-shaped pipes to ensure the filtering effect when the medium flows inside the pipeline.

[0003] Currently, when pressing partitions into flute-shaped pipes, since the partitions need to fit tightly with the inner side of the flute-shaped pipes, it is difficult for the partitions to enter the pipe end position, and it is also difficult to ensure the stability of the partitions relative to the flute-shaped pipes after the partitions are pressed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a positioning mechanism for installing partitions that can improve the pressing effect of partitions.

[0005] To solve the above technical problems, the utility model provides a positioning mechanism for installing partitions, including a material channel for conveying partitions and a partition pressing assembly arranged on one side of the material channel. The partition pressing assembly includes a cavity, a pressing rod penetrating through the inner side of the cavity, and a partition clamping die located on one side of the cavity. A material slot is opened on one side of the cavity close to the partition clamping die. The material slot matches the discharge end of the material channel and is located on one side of the end of the pressing rod. A first elastic member is connected between the cavity and the pressing rod, so that after one end of the cavity abuts against the pipe fitting, the pressing rod can extend into the inner side of the pipe fitting.

[0006] Further, a vacuum suction joint is arranged at one end of the pressing rod away from the material slot, and a negative pressure cavity communicated with the vacuum suction joint is formed inside the pressing rod, so that when one end of the pressing rod abuts against the partition, the negative pressure cavity adsorbs the side of the partition.

[0007] Further, a limiting ring groove is opened on one side of the cavity close to the partition clamping die, so that when the cavity abuts against the pipe fitting, the pipe end is buckled in the limiting ring groove; a stop air cylinder for blocking the movement of the partition is arranged at the discharge end of the material channel, so that after the previous partition enters the material slot, the subsequent partition is blocked and limited by the stop air cylinder.

[0008] Further, the partition installation and positioning mechanism further includes a flaring assembly. The flaring assembly and the partition pressing assembly are jointly arranged on a transposition seat, so that when the transposition seat moves, the processing positions of the flaring assembly and the partition pressing assembly relative to the pipe fitting are adjusted; the flaring assembly includes a movable die holder and a punch connected to the side of the die holder close to the partition clamping die, so that the punch flares the pipe end.

[0009] Further, the partition mounting and positioning mechanism further includes a grooving assembly for grooving the outer periphery of the pipe fitting. The grooving assembly includes a grooving clamping die, a moving seat movably arranged on one side of the grooving clamping die, and a sleeve rotatably mounted on one side of the moving seat. A plurality of sliding seats are arranged on the side of the sleeve close to the grooving clamping die in the circumferential direction, and the sliding seats can move relative to the radial direction of the sleeve. A roller is rotatably arranged on one side of the sliding seat. After the moving seat drives the sliding seat to approach the position of the pipe fitting to be grooved, the sliding seat drives the roller to approach the pipe fitting for grooving to form a groove, and the groove limits the annular groove on the outer periphery of the partition.

[0010] Further, the outer periphery of the roller has a grooved ring.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. The cavity positions the pipe end of the pipe fitting, and the partition is pressed into the inner side of the pipe fitting through the pressure rod, so that the pressing depth of the pressing plate is accurate enough, and the axis of the pressing plate coincides with the axis of the pipe fitting;

[0013] 2. The grooving assembly grooves the outer periphery of the pipe fitting, so that the formed grooving position matches the annular groove of the partition, and then the annular groove is positioned through the grooving position to ensure the stability of the partition.

[0043] It is understood that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "a" should not be understood as a limitation on the quantity.

[0044] As Figure 1 - 26 described, the present utility model provides a positioning mechanism for installing partitions, which is applied to a flute-shaped tube processing device. The flute-shaped tube processing device includes a non-chip cutting and blanking assembly 6, a punching and flanging component 2, a partition installing and positioning mechanism 3, a filter screen installing and positioning mechanism 4, and a sealing component 5 arranged in sequence. Among them, the conveying mode of the pipe fitting 1 between each component is to grab the pipe fitting 1 by a manipulator for movement.

[0045] Specifically, the pipe fittings in this solution are successively subjected to processes such as cutting and blanking, punching and flanging, installing partitions, grooving processing, installing filter screens, dotting, and sealing, and finally form a flute-shaped tube workpiece filled with partitions and filter screens inside. When actually processing the flute-shaped tube, the following steps can be adopted for processing:

[0046] Step 1: Load the pipe material so that the pipe material is cut and formed into a plurality of pipe fittings 1, and convey each pipe fitting 1 in sequence.

[0047] Step 2: Convey the pipe fitting 1 to the punching and flanging component 2, so that the punching and flanging component 2 performs punching processing from the inside to the outside on the position to be punched of the pipe fitting 1, so that a flanging structure 11 is formed on the outside of the pipe fitting 1 at the punching position.

[0048] Among them, the punching and flanging processing method of the punching and flanging component from the inside to the outside of the pipe fitting is the same as the existing punching and flanging method, and no specific description is made here.

[0049] Step 3: Convey the pipe fitting 1 to the partition installing and positioning mechanism 3, so that the partition installing and positioning mechanism 3 presses and installs the partition 12 inside the pipe fitting 1, and performs grooving 13 processing along the outer circumference of the pipe fitting 1, so that the groove 13 matches the annular groove 14 on the outer circumference of the partition 12.

[0050] Step 4: Convey the pipe fitting 1 to the filter screen installing and positioning mechanism 4, and press and install the filter screen 15 inside the pipe fitting 1 through the filter screen installing and positioning mechanism 4, so that one side of the filter screen 15 is closely attached to the partition 12, and perform dotting processing at several positions along the outer circumference of the pipe fitting 1, so that the positioning points 16 formed by the dotting processing limit the circumference of the filter screen 15.

[0051] Step 5: Convey the pipe fitting 1 to the sealing component 5, and perform sealing treatment on both ends of the pipe fitting 1 through the sealing component 5.

[0052] In an embodiment of the present solution, in step one, the cutting and blanking process is performed on the pipe (usually a coiled pipe in a coiled form) by the non-chip blanking assembly 6. The non-chip blanking assembly 6 includes a feed seat 61 movably arranged, a feed clamping die 62 arranged on the feed seat 61, and a cutting tool disc 63 rotatably arranged on one side of the feed clamping die 62. A through hole 64 is provided at the axial position of the cutting tool disc 63, and a plurality of sliding rods 65 are arranged along the circumferential direction of the cutting tool disc 63. The sliding rods 65 can move along the radial direction of the cutting tool disc 63. A cutting tool 66 is arranged on one of the sliding rods 65. When the end of the pipe moves through the feed clamping die 62 for a certain distance, the feed clamping die 62 clamps the pipe, and the feed seat 61 pulls the pipe to move, so that the end of the pipe passes through the position of the through hole 64 until the pipe moves to a specified distance. At this time, the distance between the end of the pipe and the cutting tool 66 is the set length of the pipe fitting 1. Subsequently, the clamping of the pipe is maintained by the fixed clamping die, and the sliding rod 65 moves along the radial direction of the cutting tool disc 63, so that the cutting tool 66 approaches the cutting position of the pipe. Then, through the rotating cutting tool disc 63, the cutting tool 66 pre-cuts the circumferential direction of the cutting position of the pipe. At this time, the cutting tool 66 only pre-cuts the circumferential direction of the pipe to form a groove, and does not directly cut off the pipe.

[0053] Among them, the feed seat 61 is controlled to move through a servo motor cooperating with a lead screw transmission structure, the cutting tool disc 63 is controlled to rotate through a servo motor cooperating with a synchronous belt transmission structure, and the sliding rod 65 and the cutting tool disc 63 form a radial sliding fit through a chute, and a spring is connected between the sliding rod 65 and the cutting tool disc 63 to ensure the stable reset of the sliding rod 65. It is worth mentioning that a sliding outer sleeve 67 is movably sleeved outside the cutting tool disc 63, and the sliding outer sleeve 67 and the sliding rod 65 are connected through an inclined surface. When the sliding outer sleeve 67 moves axially relative to the cutting tool disc 63, the inclined surface drives to drive the sliding rod 65 to move radially relative to the cutting tool disc 63. A rolling bearing is arranged between the sliding outer sleeve 67 and the cutting tool disc 63, so that when the cutting tool disc 63 rotates, the sliding outer sleeve 67 is relatively stationary to ensure the stable driving of the sliding outer sleeve for the sliding rod 65. The sliding outer sleeve 67 is controlled to axially move relative to the cutting tool disc 63 through a cylinder.

[0054] The described non-chip cutting component 6 further includes a breaking clamping die 68 movably arranged on one side of the cutting tool disc 63. After the pipe is pre-cut by the cutting tool 66, the feeding seat 61 continues to drive the pipe to move to the position of the breaking clamping die 68. Subsequently, the feeding seat 61 pauses moving. At this time, the pipe is clamped on both sides of the pre-cut by the fixed clamping die and the breaking clamping die 68 respectively, and the breaking clamping die 68 is moved, so that the pipe is broken at the pre-cut position, thereby completing the cutting and processing of the pipe fitting 1. Since the pipe fitting 1 is formed by breaking, no flying chips are generated during the formation of its end face, so as to ensure non-chip processing of the pipe fitting cutting; at the same time, after the non-chip processing of the pipe fitting 1 is completed, the breaking clamping die 68 maintains the clamping action until the manipulator picks up the pipe fitting 1. After the feeding clamping die 62 clamps the pipe by the fixed clamping die, it releases the clamping action on the pipe. At the same time, the feeding seat 61 moves back to its original position to facilitate pulling the subsequent pipes to move, so as to ensure the stable processing of the next pipe fitting.

[0055] Among them, the breaking clamping die 68 is controlled to move by a cylinder in cooperation with a guide rail, and all the clamping die structures in this solution include at least two relatively arranged clamping blocks, and the cylinder is used to control the two relatively arranged clamping blocks to clamp or release.

[0056] In another embodiment of this solution, a straightening component 7 is also arranged in the front process of the non-chip cutting component 6. The bending pipe is straightened by the straightening component 7 to ensure that the pipe fitting 1 obtained by subsequent processing is straight enough. The straightening component 7 includes a plurality of horizontally staggered straightening wheels 71, a plurality of vertically staggered straightening wheels 72, a pair of relatively arranged horizontal round straightening wheel groups 73, and a pair of relatively arranged vertical round straightening wheel groups 74. After the bending pipe passes through the above-mentioned straightening wheels and round straightening wheel groups in sequence, straightening treatment is carried out. At the same time, a supporting wheel 75 is also arranged on one side of the straightening component 7 close to the feeding seat 61. When the pipe is loaded, the lower side of the pipe contacts and is supported on the supporting wheel 75, and a micro switch is arranged at the bottom of the supporting wheel, which can be used to detect whether the pipe is in place or out of stock.

[0057] Preferably, the partition board loading and positioning mechanism 3 includes a material channel 31 for conveying the partition board 12, and a partition board pressing and loading assembly arranged on one side of the material channel 31. The partition board pressing and loading assembly includes a cavity 32, a pressing rod 33 penetrating through the inner side of the cavity 32, and a partition board clamping die 34 located on one side of the cavity 32. A material groove 35 is opened on one side of the cavity 32 close to the partition board clamping die 34. The material groove 35 matches the discharge end of the material channel 31 and is located on one side of the end of the pressing rod 33. A first elastic member is connected between the cavity 32 and the pressing rod 33, so that after one end of the cavity 32 abuts against the pipe fitting 1, the pressing rod 33 can extend into the inner side of the pipe fitting 1.

[0058] Specifically, the partition plate moves from the material channel to the material trough for preliminary positioning. At the same time, one end of the pressure rod abuts against the side of the partition plate, and the pipe fitting 1 is placed at the partition plate clamping die for clamping and fixing. Subsequently, the pressure rod moves towards the partition plate clamping die, and the cavity is pushed to move synchronously through the first elastic member until one end of the cavity abuts against the pipe fitting. At this time, the accurate positioning of the pipe end is ensured by the cavity abutting against the pipe fitting, and the pressure rod continues to move to push the partition plate into the inner side of the pipe fitting, so that the partition plate is pressed and installed at the specified position inside the pipe fitting, and the pressing depth of the partition plate is controlled by the moving distance of the pressure rod. Subsequently, the pressure rod and the cavity move back to their original positions and wait for the next pipe fitting.

[0059] Among them, the first elastic member adopts a spring structure to ensure the connection between the cavity and the pressure rod; the movement of the pressure rod is controlled by a cylinder in cooperation with a guide rail.

[0060] In an embodiment of this solution, the partition plate is initially fed through a vibrating bowl, and the discharge end of the vibrating bowl is connected to the material channel. A linear vibrator is laid at the bottom of the material channel so that the partition plate can move along the material channel.

[0061] Preferably, a vacuum suction joint 36 is provided at one end of the pressure rod 33 away from the material trough 35, and a negative pressure cavity 37 communicating with the vacuum suction joint 36 is provided inside the pressure rod 33, so that when one end of the pressure rod 33 abuts against the partition plate 12, the negative pressure cavity 37 adsorbs the side of the partition plate 12.

[0062] Specifically, by connecting a negative pressure device to the vacuum suction joint, negative pressure attraction is generated in the negative pressure cavity. Thus, when one end of the pressure rod abuts against the side of the partition plate, the side of the partition plate can be sucked by negative pressure to ensure that the partition plate will not tip over when the pressure rod pushes the partition plate.

[0063] Preferably, a limiting ring groove 38 is provided on one side of the cavity 32 close to the partition plate clamping die 34, so that when the cavity 32 abuts against the pipe fitting 1, the pipe end is buckled in the limiting ring groove 38; a stop air cylinder 39 for blocking the movement of the partition plate 12 is provided at the discharge end of the material channel 31, so that after the previous partition plate 12 enters the material trough 35, the subsequent partition plate 12 is blocked and limited by the stop air cylinder 39.

[0064] Specifically, when the cavity abuts against the pipe fitting, the pipe end is buckled by the limiting ring groove, so that the axes of the cavity and the pipe fitting are kept coincident. Furthermore, the pressing direction of the pressure rod is guided by the cavity to ensure that the moving direction of the pressure rod moves along the axis of the pipe fitting, so that the partition plate can be accurately pressed into the inner side of the pipe fitting along the axis of the pipe fitting.

[0065] At the same time, due to the setting of the stop air cylinder, after the previous partition plate enters the material trough, the telescopic rod of the stop air cylinder extends, and the subsequent partition plate in the material channel is blocked and limited, so as to avoid the situation that the partition plate still falls when the pressure rod drives the cavity to move and causes the dislocation of the material trough and the material channel, resulting in the partition plate being unable to accurately enter the material trough.

[0066] Preferably, the partition mounting and positioning mechanism 3 further includes a flaring assembly, and the flaring assembly and the partition pressing assembly are jointly arranged on the transposition seat 310, so that when the transposition seat 310 moves, the processing positions of the flaring assembly and the partition pressing assembly relative to the pipe fitting 1 are adjusted; the flaring assembly includes a die holder 311 movably arranged, and a punch 312 connected to the die holder 311 close to the partition clamping die 34 side, so that the punch 312 flares the pipe end.

[0067] Specifically, since the partition in this solution is in close fit with the inner side of the pipe fitting, it is difficult for the partition to enter the pipe end position. Therefore, this solution sets a flaring assembly. Before pressing the partition, the transposition seat is used to transpose the flaring assembly and the partition pressing assembly first, so that the punch is aligned with the pipe end position. At this time, the die holder drives the punch to approach the pipe end, and the pipe end is flared by the punch, so that the pressing plate can more easily enter the pipe end position.

[0068] Among them, the transposition seat is controlled to transpose and move through a cylinder cooperating with a guide rail, and the die holder is controlled to move through a cylinder cooperating with a guide rail.

[0069] It is worth mentioning that when the transposition seat drives the flaring assembly and the partition pressing assembly to transpose and move, it will also cause the material channel and the material groove to be misaligned. Therefore, when the flaring assembly performs the flaring process, it is also necessary to block the partition at the material channel through a stop cylinder.

[0070] Preferably, the partition mounting and positioning mechanism 3 further includes a grooving assembly for grooving the outer circumference of the pipe fitting 1. The grooving assembly includes a grooving clamping die 313, a moving seat 314 movably arranged on one side of the grooving clamping die 313, and a sleeve 315 rotatably installed on one side of the moving seat 314. A plurality of sliding seats 316 are arranged along the circumference on the side of the sleeve 315 close to the grooving clamping die 313, and the sliding seats 316 can move relative to the radial direction of the sleeve 315. A roller 317 is rotatably arranged on one side of the sliding seat 316, and a grooving ring 318 is arranged on the outer circumference of the roller 317. After the moving seat 314 drives the sliding seat 316 to approach the grooving position of the pipe fitting 1, the sliding seat 316 drives the roller 317 to approach the pipe fitting 1 and perform grooving to form a groove 13, and the groove 13 limits the annular groove 14 on the outer circumference of the partition 12.

[0071] Specifically, after the partition plate is pressed into the inner side of the pipe fitting, the pipe fitting is conveyed to the rotary groove clamping die for clamping and fixing. Subsequently, the moving seat drives the sleeve to move towards the pipe fitting until the roller moves to a position corresponding to the annular groove on the outer periphery of the partition plate. Then, the sleeve rotates relative to the moving seat, and at the same time, the sliding seat moves along the radial direction of the sleeve, so that the roller approaches the outer side of the pipe fitting while rotating, and the outer periphery of the pipe fitting is processed by the rotary groove ring, so that the formed rotary groove is recessed towards the inner side of the pipe fitting and clamped in the annular groove, so as to position the partition plate by the rotary groove.

[0072] Among them, the moving seat is controlled to move through the cooperation of a servo motor and a lead screw drive, and the sleeve is controlled to rotate by a servo motor on one side of the moving seat; a sliding sleeve 319 is movably sleeved outside the sleeve 315, and the sliding sleeve 319 is connected to the sliding seat 316 through an inclined surface, so that when the sliding sleeve 319 moves axially relative to the sleeve 315, it drives the sliding seat 316 to move radially relative to the sleeve 315 through the inclined surface drive. And a rolling bearing is arranged between the sliding sleeve 319 and the sleeve 315, so that when the sleeve 315 rotates, the sliding sleeve 319 is relatively stationary to ensure the stable drive of the sliding sleeve 319 to the sliding seat 316. The sliding sleeve 319 is controlled to axially move relative to the sleeve 315 through the cooperation of a servo motor and a lead screw drive; and a spring is connected between the sliding seat 316 and the sleeve 315, so that after the sliding sleeve 319 moves and resets, the sliding seat 316 can be pushed to reset by the spring.

[0073] Preferably, the filter screen loading and positioning mechanism 4 includes a vibrating disk 41 for feeding the filter screen 15, a filter screen pressing assembly 42 arranged on one side of the vibrating disk 41, a first picking air gripper 43 for picking up materials from the discharge end of the vibrating disk 41, and a second picking air gripper 44 for conveying the filter screen 15 from the first picking air gripper 43 to the filter screen pressing assembly 42, so that the filter screen 15 enters the filter screen pressing assembly 42 for pressing treatment after passing through the vibrating disk 41, the first picking air gripper 43 and the second picking air gripper 44 in sequence; the filter screen pressing assembly 42 includes a movably arranged pressing rod 45, an outer sleeve 46 movably sleeved on the outer periphery of the pressing rod 45, a second elastic member 47 for connecting the pressing rod 45 and the outer sleeve 46, and a filter screen clamping die 48 arranged on one side of the pressing rod 45. A filter screen installation position is formed between the end of the pressing rod 45 and the end of the outer sleeve 46, so that when the filter screen 15 is placed in the filter screen installation position, the outer sleeve 46 is sleeved on the outer periphery of the filter screen 15, and the grid part of the filter screen 15 is placed inside the pressing rod 45.

[0074] Specifically, the vibrating bowl is used to feed the filter screen. Subsequently, the first picking gripper clamps the filter screen from the discharge end of the vibrating bowl, and the second picking gripper transports the filter screen from the first picking gripper to the filter screen pressing assembly, so that the filter screen is placed at the filter screen installation position. The outer sleeve is sleeved on the outer periphery of the filter screen, and at the same time, the grid part of the filter screen is placed inside the pressing rod to facilitate positioning of the filter screen. At this time, the pipe fitting is clamped at the filter screen clamping die. Subsequently, the pressing rod drives the outer sleeve to move to the pipe end and makes the outer sleeve abut against the pipe end. The pressing rod continues to push the filter screen into the inner side of the pipe fitting, and the pressing depth of the filter screen is controlled by the moving distance of the pressing rod until one side of the filter screen abuts against the side of the partition board.

[0075] Among them, the pressing rod is controlled to move through the cooperation of a servo motor and a lead screw drive, and the second elastic member adopts a spring structure.

[0076] It is worth mentioning that when feeding the filter screen through the first picking gripper and the second picking gripper, first, the first picking gripper clamps and grabs both sides of the filter screen horizontally placed at the discharge end of the vibrating bowl, and drives the filter screen to move upward through the first picking gripper to separate it from the vibrating bowl. Subsequently, the first picking gripper rotates counterclockwise by 90°, making the first picking gripper vertically placed. At this time, the second picking gripper moves to one side of the filter screen and supports and fixes the filter screen by means of internal support, so as to move the filter screen from the first picking gripper to the second picking gripper. Subsequently, the second picking gripper moves and descends to one side of the pressing rod and places the filter screen in the filter screen installation position.

[0077] Among them, the moving, rotating, and lifting modes of the first picking gripper and the second picking gripper are all controlled and driven by a cylinder or a servo motor in cooperation with a guide rail.

[0078] Preferably, one end of the outer sleeve 46 close to the pipe fitting 1 has a pipe end limit groove 49, so that when the outer sleeve 46 abuts against the pipe fitting 1, the pipe end is buckled in the pipe end limit groove 49.

[0079] Specifically, when the outer sleeve abuts against the pipe fitting, the circumferential direction of the pipe end is limited by the pipe end limit groove, so that the axis of the pipe fitting coincides with the outer sleeve, thereby ensuring that the filter screen is accurately pressed into the inner side of the pipe fitting.

[0080] Preferably, a dotting seat 410 is arranged on the outer periphery of the pressing rod 45. A plurality of sliders 411 are arranged along the circumferential direction on one side of the dotting seat 410 close to the filter screen clamping die 48. The sliders 411 can move along the radial direction of the dotting seat 410, and a dotting needle 412 is connected to one side of the sliders 411. When the sliders 411 move relative to the radial direction of the dotting seat 410 and approach the pipe fitting 1, the dotting needle 412 performs dotting processing on the outer periphery of the pipe fitting 1 to form positioning points 16, and the circumferential direction of the filter screen 15 is limited by the positioning points 16.

[0081] Specifically, after the filter screen is press-fitted, the press-fitting rod maintains the press-fitting action on the filter screen to ensure that the filter screen abuts against the partition plate. Subsequently, a plurality of sliders move radially relative to the dotting seat, so that the dotting needle approaches and dots the outer periphery of the pipe fitting to form positioning points, and the positioning points limit the outer periphery of the filter screen to ensure the stability of the filter screen.

[0082] Preferably, a sliding sleeve 413 is movably sleeved on the outer periphery of the dotting seat 410. The sliding sleeve 413 can move axially relative to the dotting seat 410, and the sliding sleeve 413 and the slider 411 are connected by an inclined surface. When the sliding sleeve 413 moves axially relative to the dotting seat 410, the slider 411 moves radially relative to the dotting seat 410; a plurality of avoidance grooves 414 matching the dotting needles 412 are circumferentially formed at the end of the press-fitting rod 45, so that when the dotting needles 412 dot the pipe fitting 1, the dotting needles 412 pass through the avoidance grooves 414.

[0083] Specifically, since a sliding sleeve 413 is movably sleeved outside the dotting seat 410 and the sliding sleeve 413 and the slider 411 are connected by an inclined surface, when the sliding sleeve 413 moves axially relative to the dotting seat 410, the slider 411 is driven by the inclined surface to move radially relative to the dotting seat 410. The sliding sleeve 413 is controlled by a cylinder to move axially relative to the dotting seat 410; and a spring is connected between the slider 411 and the dotting seat 410, so that after the sliding sleeve 413 moves back to its original position, the slider 411 can be pushed back to its original position by the spring.

[0084] It is worth mentioning that after the filter screen and the pipe fitting are press-fitted, the pipe fitting is conveyed to the sealing component 5 by a manipulator for sealing the two pipe ends. The sealing processing method here is the same as the existing sealing processing method, so no specific description is given; particularly, after one end of the pipe fitting is sealed, the pipe fitting is grabbed by the manipulator and flipped by 180°, so that the other end of the pipe fitting faces the sealing component, and then the two pipe ends can be sealed by the same sealing component.

[0085] The present invention is not limited to the above best implementation manner. Any person can obtain other various forms of products under the inspiration of the present invention. However, no matter what changes are made in its shape or structure, as long as it has a technical solution identical or similar to the present application, it falls within the protection scope of the present invention.
