Description

Technical Field

[0001] This invention relates to the field of pipe processing equipment, and in particular to a flute-shaped pipe processing equipment. Background Technology

[0002] Flute tubes are commonly used for connecting air conditioning pipes. Due to their numerous openings, their manufacturing process is quite complicated. Furthermore, baffles and filters need to be installed inside the flute tubes to ensure the filtration effect of the medium flowing inside the pipes.

[0003] Furthermore, due to the complexity of the internal structure of air conditioning pipes, when using a flute-shaped pipe as one section of the air conditioning pipe, it is usually used as the main pipe to ensure that the air conditioning pipe as a whole can adapt to a more complex environment. When the flute-shaped pipe is used as the main air conditioning pipe, it is necessary to add baffles and filter screens inside the flute-shaped pipe to ensure that the flute-shaped pipe can filter the air conditioning pipe.

[0004] However, the current processing of flute tubes usually requires sequential steps such as cutting and shaping, punching, installing partitions, positioning partitions, installing filters, positioning filters, and sealing. Each of these steps typically requires multiple specialized equipment. The transfer between these equipment platforms significantly reduces the overall processing efficiency of the flute tubes and makes it difficult to ensure that the positioning accuracy of each piece of equipment is matched.

[0005] Furthermore, since flute-shaped tubes are mainly used in the main pipelines of air conditioning systems, they usually need to be connected to other pipelines. Therefore, the processing precision of flute-shaped tubes is relatively high to ensure normal connection with other pipelines and to prevent abnormalities in the air conditioning system. Summary of the Invention

[0006] The purpose of this invention is to provide a flute-shaped tube processing device that solves the above-mentioned technical problems.

[0007] To solve the above-mentioned technical problems, the present invention provides a flute-shaped tube processing equipment, including a chipless cutting assembly, a punching and flanging component, a partition and positioning mechanism, a filter and positioning mechanism, and a sealing component arranged in sequence; the chipless cutting assembly includes a feed seat that is movably arranged, a feed clamping mold arranged on the feed seat, and a cutting disc that is rotatably arranged on one side of the feed clamping mold. A through hole is opened at the axial position of the cutting disc, and a plurality of slide rods are arranged around the cutting disc. The slide rods can move radially along the cutting disc, and a cutting blade is arranged on one of the slide rods.

[0008] Furthermore, the partition plate mounting and positioning mechanism includes a material channel for conveying the partition plate and a partition plate pressing assembly disposed on one side of the material channel. The partition plate pressing assembly includes a cavity, a pressure rod passing through the inside of the cavity, and a partition plate clamping mold located on one side of the cavity. A material groove is provided on the side of the cavity near the partition plate clamping mold. The material groove matches the discharge end of the material channel and is located on one side of the end of the pressure rod. A first elastic element is connected between the cavity and the pressure rod so that after one end of the cavity abuts against the pipe, the pressure rod can extend into the inside of the pipe.

[0009] Furthermore, a vacuum suction connector is provided at the end of the pressure rod away from the material trough, and a negative pressure cavity communicating with the vacuum suction connector is provided on the inner side of the pressure rod, so that when one end of the pressure rod abuts against the partition, the negative pressure cavity adsorbs the side of the partition.

[0010] Furthermore, a limiting annular groove is provided on the side of the cavity near the partition clamping mold, so that when the cavity abuts against the pipe, the pipe end is fastened in the limiting annular groove; the discharge end of the material channel is provided with a blocking cylinder for blocking the movement of the partition, so that after the previous partition enters the material channel, the next partition is blocked and limited by the blocking cylinder.

[0011] Furthermore, the partition plate and positioning mechanism also includes a flaring assembly, which is jointly disposed on the shifting seat with the partition plate pressing assembly, so that when the shifting seat moves, the processing position of the flaring assembly and the partition plate pressing assembly relative to the pipe fitting is adjusted; the flaring assembly includes a movable die base and a punch connected to the die base near the partition plate clamping die, so that the punch flares the pipe end.

[0012] Furthermore, the partition plate and positioning mechanism also includes a grooving assembly for grooving the outer circumference of the pipe fitting. The grooving assembly includes a grooving mold, a movable seat movably disposed on one side of the grooving mold, and a sleeve rotatably mounted on one side of the movable seat. The sleeve has several sliding blocks arranged circumferentially on the side near the grooving mold, and the sliding blocks can move radially relative to the sleeve. A roller is rotatably disposed on one side of the sliding block, and the outer circumference of the roller has a grooving ring. After the movable seat drives the sliding block to approach the grooving position of the pipe fitting, the sliding block drives the roller to approach the pipe fitting and perform grooving to form a grooving groove, and the grooving groove limits the annular groove on the outer circumference of the partition plate.

[0013] Furthermore, the filter screen loading and positioning mechanism includes a vibratory feeder for loading the filter screen, a filter screen pressing assembly located on one side of the vibratory feeder, a first picking gripper for picking up material from the discharge end of the vibratory feeder, and a second picking gripper for conveying the filter screen from the first picking gripper to the filter screen pressing assembly, so that the filter screen passes sequentially through the vibratory feeder, the first picking gripper, and the second picking gripper before entering the filter screen pressing assembly for pressing. The filter screen pressing assembly includes a movable pressing rod, a movable outer sleeve fitted around the outer periphery of the pressing rod, a second elastic element for connecting the pressing rod and the outer sleeve, and a filter screen clamping mold located on one side of the pressing rod. A filter screen mounting position is formed between the end of the pressing rod and the end of the outer sleeve, so that when the filter screen is placed in the filter screen mounting position, the outer sleeve is fitted around the outer periphery of the filter screen, and the mesh portion of the filter screen is placed inside the pressing rod.

[0014] Furthermore, the outer sleeve has a pipe end limiting groove at one end near the pipe fitting, so that when the outer sleeve abuts against the pipe fitting, the pipe end is fastened in the pipe end limiting groove.

[0015] Furthermore, a dotting seat is provided on the outer periphery of the pressing rod. Several sliders are provided circumferentially on the side of the dotting seat near the filter screen clamping mold. The sliders can move radially along the dotting seat, and a dotting needle is connected to one side of the slider so that when the slider moves radially relative to the dotting seat and approaches the pipe, the dotting needle performs dotting processing on the outer periphery of the pipe to form positioning points, and the positioning points limit the circumferential movement of the filter screen.

[0016] Furthermore, a sliding sleeve is provided on the outer periphery of the dotting seat. The sliding sleeve can move axially relative to the dotting seat, and the sliding sleeve and the slider are connected by an inclined surface, so that when the sliding sleeve moves axially relative to the dotting seat, the slider moves radially relative to the dotting seat. The end of the pressing rod is provided with several clearance grooves that match the dotting needles, so that when the dotting needles are used to dot the pipe fitting, the dotting needles pass through the clearance grooves.

[0017] The beneficial effects of this invention are as follows: 1. By integrating processes such as cutting, punching, installing partitions and positioning, installing filters and positioning, and sealing into one machine, the conveying and transfer between processes becomes more efficient, and the positioning accuracy between processes is improved. 2. The punching and flanging components are used to punch holes from the inside to the outside of the pipe fitting, so that the flanging structure can be formed simultaneously during punching, ensuring the convenience of connecting the flute-shaped pipe to other pipelines. 3. The cavity positions the pipe end of the fitting, and the pressure bar presses the partition plate into the inside of the fitting, so that the pressing depth of the pressure plate is accurate enough and the axis of the pressure plate coincides with the axis of the fitting. 4. The outer circumference of the pipe is grooved by the grooving assembly so that the position of the grooving groove matches the annular groove of the partition plate. The position of the grooving groove is then used to position the annular groove to ensure the stability of the partition plate. 5. The outer sleeve and pressing rod limit the outer periphery and mesh of the filter screen respectively, improving the pressing accuracy of the filter screen. At the same time, the outer sleeve positions the tube end during the pressing process of the filter screen, further improving the pressing accuracy of the filter screen relative to the tube fitting. 6. By making several dots on the outer periphery of the pipe fitting, positioning points are formed so that the positioning points limit the outer periphery of the filter screen, thereby improving the stability of the filter screen.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0046] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0047] 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 another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0048] like Figure 1-26The present invention provides a flute-shaped tube processing equipment, comprising a chipless cutting assembly 6, a punching and flanging component 2, a partition and positioning mechanism 3, a filter and positioning mechanism 4, and a sealing component 5 arranged sequentially; wherein the tube 1 is conveyed between the components by a robotic arm gripping and moving the tube 1.

[0049] Specifically, the pipe fittings in this solution undergo a series of processes including cutting, punching and flanging, installing baffles, grooving, installing filters, marking, and sealing, ultimately forming a flute-shaped tube filled with baffles and a filter. In actual processing of the flute-shaped tube, the following steps can be used: Step 1: Feed the pipe material to cut it into several pipe fittings 1, and then convey each pipe fitting 1 in sequence. Step 2: The pipe fitting 1 is transported to the punching and flanging component 2, so that the punching and flanging component 2 punches the position to be punched on the pipe fitting 1 from the inside out, so that the punching position forms a flanging structure 11 on the outside of the pipe fitting 1. The punching and flanging component uses the same punching and flanging process for pipe fittings from the inside out, which is consistent with the existing punching and flanging process and will not be described in detail here.

[0050] Step 3: Transport the pipe fitting 1 to the partition plate and positioning mechanism 3, so that the partition plate and positioning mechanism 3 presses the partition plate 12 into the inner side of the pipe fitting 1, and performs a rotary groove 13 along the outer periphery of the pipe fitting 1, so that the rotary groove 13 matches the annular groove 14 on the outer periphery of the partition plate 12. Step 4: Transport the pipe fitting 1 to the filter screen and positioning mechanism 4. Press the filter screen 15 into the inside of the pipe fitting 1 through the filter screen and positioning mechanism 4, so that one side of the filter screen 15 is tightly attached to the partition plate 12. Make several dots along the outer periphery of the pipe fitting 1 so that the positioning points 16 formed by the dotting process limit the circumference of the filter screen 15. Step 5: Transport pipe fitting 1 to sealing component 5, and seal both ends of pipe fitting 1 through sealing component 5.

[0051] In one embodiment of this solution, the cutting and sizing process in step one is performed by a chipless cutting assembly 6 on the pipe (usually a coiled pipe). The chipless cutting assembly 6 includes a movable feeding seat 61, a feeding clamping mold 62 disposed on the feeding seat 61, and a cutting disc 63 rotatably disposed on one side of the feeding clamping mold 62. The cutting disc 63 has a through hole 64 at its axial position, and several sliding rods 65 are arranged circumferentially on the cutting disc 63. The sliding rods 65 can move radially along the cutting disc 63, and a cutting blade 66 is disposed on one of the sliding rods 65. After the end of the pipe moves through the feeding clamping mold 62 for a certain distance, the feeding clamping mold 62 cuts the pipe. The pipe is clamped and moved by the feed seat 61, so that the end of the pipe passes through the through hole 64 until the pipe moves to the specified distance. At this time, the distance between the end of the pipe and the cutting blade 66 is the set length of the pipe 1. Then, the pipe is clamped by the fixed clamping mold and moved radially along the cutting blade disk 63 by the slide rod 65, so that the cutting blade 66 moves closer to the part of the pipe to be cut. Then, by the rotating cutting blade disk 63, the cutting blade 66 pre-cuts the part of the pipe to be cut in the circumference. At this time, the cutting blade 66 only pre-cuts the circumference of the pipe to form a groove, and does not directly cut the pipe.

[0052] The feeding seat 61 is moved by a servo motor and a lead screw drive structure. The cutting disc 63 is rotated by a servo motor and a synchronous belt drive structure. The sliding rod 65 and the cutting disc 63 are radially slidingly engaged by a sliding groove, and a spring is connected between the sliding rod 65 and the cutting disc 63 to ensure the stable return of the sliding rod 65. It is worth mentioning that the outer moving sleeve of the cutting disc 63 is equipped with a sliding outer sleeve 67. The sliding outer sleeve 67 and the sliding rod 65 are connected by an inclined plane. When the sliding outer sleeve 67 moves axially relative to the cutting disc 63, the inclined plane drives the sliding rod 65 to move radially relative to the cutting disc 63. A rolling bearing is provided between the sliding outer sleeve 67 and the cutting disc 63, so that when the cutting disc 63 rotates, the sliding outer sleeve 67 remains relatively stationary to ensure the stable drive of the sliding outer sleeve on the sliding rod 65. The axial movement of the sliding outer sleeve 67 relative to the cutting disc 63 is controlled by a cylinder.

[0053] The chipless cutting assembly 6 also includes a break-off clamping mold 68 movably disposed on one side of the cutting disc 63. After the pipe is pre-cut by the cutting blade 66, the feeding seat 61 continues to move the pipe to the break-off clamping mold 68. Then the feeding seat 61 stops moving. At this time, the fixed clamping mold and the break-off clamping mold 68 clamp the two sides of the pre-cut pipe respectively, and the break-off clamping mold 68 moves so that the pipe is broken at the pre-cut position, thereby completing the cutting process of the pipe 1. Since the pipe 1 is formed by break-off, no flying chips will be generated during its end face formation process, so as to ensure chipless processing of the pipe cutting process. At the same time, after the chipless processing of the pipe 1 is completed, the break-off clamping mold 68 maintains the clamping action until the robot arm picks up the pipe 1. After the fixed clamping mold clamps the pipe, the feeding clamping mold 62 releases the clamping action on the pipe. At the same time, the feeding seat 61 moves back to its original position so as to continue to pull the subsequent pipes to move, so as to ensure the processing stability of the next pipe.

[0054] The pull-off clamping mold 68 is controlled to move by a cylinder in conjunction with a guide rail, and all clamping mold structures in this solution include at least two oppositely arranged clamping blocks, which are clamped or released by the cylinder.

[0055] In another embodiment of this solution, a straightening component 7 is also provided in the process before the chipless cutting assembly 6. The straightening component 7 straightens the bent pipe to ensure that the pipe 1 obtained in subsequent processing is straight enough. The straightening component 7 includes several horizontal straightening wheels 71 arranged in an alternating manner, several vertical straightening wheels 72 arranged in an alternating manner, a horizontal rounding wheel group 73 arranged in opposite directions, and a vertical rounding wheel group 74 arranged in opposite directions. The bent pipe passes through the above-mentioned straightening wheels and rounding wheel groups in sequence for straightening. At the same time, a support wheel 75 is also provided on the side of the straightening component 7 near the feeding seat 61. When the pipe is fed, the lower side of the pipe contacts and is supported on the support wheel 75. The bottom of the support wheel has a micro switch, which can be used to detect whether the pipe is in place or missing material.

[0056] Preferably, the partition plate mounting and positioning mechanism 3 includes a material channel 31 for conveying the partition plate 12 and a partition plate pressing assembly disposed on one side of the material channel 31. The partition plate pressing assembly includes a cavity 32, a pressure rod 33 passing through the inside of the cavity 32, and a partition plate clamping mold 34 located on one side of the cavity 32. A material groove 35 is provided on the side of the cavity 32 near the partition plate clamping mold 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 pressure rod 33. A first elastic element is connected between the cavity 32 and the pressure rod 33 so that after one end of the cavity 32 abuts against the pipe 1, the pressure rod 33 can extend into the inside of the pipe 1.

[0057] Specifically, the partition moves from the material channel to the material trough for initial positioning, while one end of the pressure rod abuts against the side of the partition. The pipe fitting 1 is placed in the partition clamping mold for clamping and fixing. Then, the pressure rod moves towards the partition clamping mold and pushes the cavity to move synchronously through the first elastic element until one end of the cavity abuts against the pipe fitting. At this point, the cavity and the pipe fitting abut against each other to ensure accurate positioning of the pipe end. The pressure rod continues to move to push the partition into the inside of the pipe fitting, so that the partition is pressed into the designated position inside the pipe fitting. The pressing depth of the partition is controlled by the moving distance of the pressure rod. Then, the pressure rod and the cavity move and reset, waiting for the next pipe fitting.

[0058] The first elastic element adopts a spring structure to ensure the connection between the cavity and the pressure rod; the pressure rod is controlled to move by a cylinder in conjunction with a guide rail.

[0059] In one embodiment of this solution, the partition is initially fed by a vibratory feeder, and the discharge end of the vibratory feeder is connected to the material channel. A linear vibrator is laid at the bottom of the material channel so that the partition can move along the material channel.

[0060] Preferably, the end of the pressure rod 33 away from the material trough 35 is provided with a vacuum suction joint 36, and the inner side of the pressure rod 33 has a negative pressure cavity 37 that communicates with the vacuum suction joint 36, so that when one end of the pressure rod 33 abuts against the partition 12, the negative pressure cavity 37 adsorbs the side of the partition 12.

[0061] Specifically, by connecting the negative pressure device to the vacuum suction connector, a negative pressure is generated in the negative pressure chamber, which in turn allows the side of the partition to be held in place by the negative pressure when one end of the pressure rod is pressed against the side of the partition, thus ensuring that the partition will not tilt when the pressure rod pushes against it.

[0062] Preferably, a limiting annular groove 38 is provided on the side of the cavity 32 near the partition clamping mold 34, so that when the cavity 32 abuts against the pipe 1, the pipe end is fastened in the limiting annular groove 38; the discharge end of the material channel 31 is provided with a blocking cylinder 39 for blocking the movement of the partition 12, so that after the previous partition 12 enters the material groove 35, the subsequent partition 12 is blocked and limited by the blocking cylinder 39.

[0063] Specifically, when the cavity abuts against the pipe fitting, the pipe end is fastened by the limiting ring groove, so that the axis of the cavity and the pipe fitting are aligned. Then, the cavity guides the pressing direction of the pressure rod to ensure that the moving direction of the pressure rod is along the axis of the pipe fitting, so that the partition can be accurately pressed into the inside of the pipe fitting along the axis of the pipe fitting.

[0064] Meanwhile, due to the setting of the material blocking cylinder, after the front partition enters the material trough, the extension rod of the material blocking cylinder extends and limits and blocks the rear partition in the material channel, so as to prevent the partition from falling down when the pressure rod drives the cavity to move and causes the material trough and material channel to be misaligned, thus preventing the partition from accurately entering the material trough.

[0065] Preferably, the partition plate mounting and positioning mechanism 3 further includes a flaring assembly, which is jointly disposed on the shifting seat 310 with the partition plate pressing assembly, so that when the shifting seat 310 moves, the processing position of the flaring assembly and the partition plate pressing assembly relative to the pipe fitting 1 is adjusted; the flaring assembly includes a movable punching die seat 311 and a punch 312 connected to the punching die seat 311 near the partition plate clamping die 34, so that the punch 312 flares the pipe end.

[0066] Specifically, since the partition plate and the inner side of the pipe fitting are tightly fitted in this solution, it is difficult for the partition plate to enter the pipe end position. Therefore, this solution is equipped with a flaring assembly. Before pressing the partition plate, the flaring assembly and the partition plate pressing assembly are first switched by the shifting seat so that the punch is aligned with the pipe end position. At this time, the die holder drives the punch to move closer to the pipe end and performs flaring treatment on the pipe end by the punch, so that the pressing plate can enter the pipe end position more easily.

[0067] The shifting seat is controlled by a cylinder in conjunction with a guide rail for shifting and movement, and the punching die seat is controlled by a cylinder in conjunction with a guide rail for movement.

[0068] It is worth mentioning that when the shifting seat moves the flaring assembly and the partition pressing assembly, it will also cause the material channel and the material trough to misalign. Therefore, when the flaring assembly is flaring, it is also necessary to use the material blocking cylinder to block the partition at the material channel.

[0069] Preferably, the partition plate and positioning mechanism 3 further includes a grooving assembly for grooving the outer periphery of the pipe fitting 1. The grooving assembly includes a grooving mold 313, a movable seat 314 movably disposed on one side of the grooving mold 313, and a sleeve 315 rotatably mounted on one side of the movable seat 314. The sleeve 315 is provided with a plurality of slides 316 circumferentially on the side near the grooving mold 313, and the slides 316 can move radially relative to the sleeve 315. A roller 317 is rotatably disposed on one side of the slides 316, and the outer periphery of the roller 317 has a grooving ring 318. After the movable seat 314 drives the slides 316 to approach the grooving position of the pipe fitting 1, the slides 316 drive the rollers 317 to approach the pipe fitting 1 and perform grooving to form a grooving groove 13, and the grooving groove 13 limits the annular groove 14 on the outer periphery of the partition plate 12.

[0070] Specifically, after the partition plate is pressed into the inside of the pipe fitting, the pipe fitting is transported to the grooving mold for clamping and fixing. Then, the moving seat drives the sleeve to move towards the pipe fitting until the roller moves to the position corresponding to the annular groove on the outer circumference of the partition plate. Then, the sleeve rotates relative to the moving seat, while the slide moves radially along the sleeve, so that the roller moves closer to the outside of the pipe fitting while rotating. The grooving ring performs grooving on the outer circumference of the pipe fitting, so that the formed grooving groove is recessed into the inside of the pipe fitting and locked in the annular groove, so that the grooving groove positions the partition plate.

[0071] The movable seat is controlled to move via a servo motor and a lead screw drive, while the sleeve is controlled to rotate via a servo motor on one side of the movable seat. A sliding sleeve 319 is mounted on the outside of the sleeve 315. The sliding sleeve 319 is connected to the slide block 316 via an inclined plane, allowing the sliding sleeve 319 to move axially relative to the sleeve 315, which in turn drives the slide block 316 to move radially relative to the sleeve 315. A rolling bearing is provided between the sliding sleeve 319 and the sleeve 315, ensuring that the sliding sleeve 319 remains relatively stationary while the sleeve 315 rotates, thus guaranteeing stable driving of the sliding sleeve 319 on the slide block 316. The axial movement of the sliding sleeve 319 relative to the sleeve 315 is controlled by a servo motor and a lead screw drive. A spring connects the slide block 316 and the sleeve 315, allowing the slide block 316 to reset via the spring after the sliding sleeve 319 has moved and reset.

[0072] Preferably, the filter screen loading and positioning mechanism 4 includes a vibratory feeder 41 for feeding the filter screen 15, a filter screen pressing assembly 42 disposed on one side of the vibratory feeder 41, a first picking-up air gripper 43 for picking up material from the discharge end of the vibratory feeder 41, and a second picking-up air gripper 44 for conveying the filter screen 15 from the first picking-up air gripper 43 to the filter screen pressing assembly 42, so that the filter screen 15 enters the filter screen pressing assembly 42 after passing through the vibratory feeder 41, the first picking-up air gripper 43, and the second picking-up air gripper 44 in sequence. Press-fitting process; the filter press-fitting assembly 42 includes a press-fitting rod 45 that is movably disposed, an outer sleeve 46 that is movably sleeved on the outer periphery of the press-fitting rod 45, a second elastic element 47 for connecting the press-fitting rod 45 and the outer sleeve 46, and a filter clamping mold 48 disposed on one side of the press-fitting rod 45. A filter mounting position is formed between the end of the press-fitting rod 45 and the end of the outer sleeve 46, so that when the filter 15 is placed in the filter mounting position, the outer sleeve 46 is sleeved on the outer periphery of the filter 15, and the mesh portion of the filter 15 is placed inside the press-fitting rod 45.

[0073] Specifically, the filter screen is fed by a vibratory feeder. Then, the first pick-up gripper clamps the filter screen from the discharge end of the vibratory feeder, and the second pick-up gripper transports the filter screen from the first pick-up gripper to the filter screen pressing assembly. The filter screen is placed in the filter screen mounting position and is fitted onto the outer periphery of the filter screen by an outer sleeve. At the same time, the mesh part of the filter screen is placed inside the pressing rod to facilitate the positioning of the filter screen. At this time, the pipe is clamped at the filter screen clamping mold. Then, 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 to the inside of the pipe. 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 plate.

[0074] The pressing rod is controlled to move by a servo motor in conjunction with a lead screw drive, and the second elastic element adopts a spring structure.

[0075] It is worth mentioning that when feeding the filter screen using the first and second picking air grippers, the first picking air gripper first clamps and grabs both sides of the filter screen, which is placed horizontally at the discharge end of the vibratory plate. The first picking air gripper then moves the filter screen upward to detach it from the vibratory plate. Subsequently, the first picking air gripper rotates 90° counterclockwise to make it vertical. At this time, the second picking air gripper moves to one side of the filter screen and supports and fixes the filter screen by means of an internal brace, so as to move the filter screen from the first picking air gripper to the second picking air gripper. Then, the second picking air gripper moves and descends to the side of the pressing rod and places the filter screen in the filter screen installation position.

[0076] The movement, rotation, and lifting of the first and second picking grippers are all controlled and driven by cylinders or servo motors in conjunction with guide rails.

[0077] Preferably, the outer sleeve 46 has a pipe end limiting groove 49 at the end near the pipe fitting 1, so that when the outer sleeve 46 abuts against the pipe fitting 1, the pipe end is fastened in the pipe end limiting groove 49.

[0078] Specifically, when the outer sleeve abuts against the fitting, the circumferential of the pipe end is limited by the pipe end limiting groove so that the axis of the fitting coincides with the outer sleeve, thereby ensuring that the filter screen is accurately pressed into the inside of the fitting.

[0079] Preferably, a dotting seat 410 is provided on the outer periphery of the pressing rod 45. A plurality of sliders 411 are provided circumferentially on the side of the dotting seat 410 near the filter screen clamping mold 48. The sliders 411 can move radially along the dotting seat 410, and a dotting needle 412 is connected to one side of the slider 411. When the slider 411 moves radially relative to the dotting seat 410 and approaches the pipe 1, the dotting needle 412 performs dotting processing on the outer periphery of the pipe 1 to form positioning points 16, and the positioning points 16 limit the circumferential movement of the filter screen 15.

[0080] Specifically, after the filter screen is pressed in, the pressing rod maintains the pressing action on the filter screen to ensure that the filter screen is against the partition. Then, several sliders move radially relative to the dotting seat, so that the dotting needles approach and dot the outer periphery of the pipe to form positioning points. The positioning points limit the outer periphery of the filter screen to ensure the stability of the filter screen.

[0081] Preferably, the outer periphery of the dotting seat 410 is fitted with a sliding sleeve 413, which can move axially relative to the dotting seat 410. The sliding sleeve 413 and the slider 411 are connected by an inclined surface, so that when the sliding sleeve 413 moves axially relative to the dotting seat 410, the slider 411 moves radially relative to the dotting seat 410. The end of the pressing rod 45 is provided with a plurality of clearance grooves 414 that match the dotting needle 412, so that when the dotting needle 412 performs dotting processing on the pipe fitting 1, the dotting needle 412 passes through the clearance grooves 414.

[0082] Specifically, since the outer movable sleeve of the marking base 410 is equipped with a sliding sleeve 413, and the sliding sleeve 413 and the slider 411 are connected by an inclined plane, when the sliding sleeve 413 moves axially relative to the marking base 410, the slider 411 moves radially relative to the marking base 410 by the inclined plane drive. The axial movement of the sliding sleeve 413 relative to the marking base 410 is controlled by a cylinder. Furthermore, a spring is connected between the slider 411 and the marking base 410, so that after the sliding sleeve 413 moves and resets, the slider 411 can be reset by the spring.

[0083] It is worth mentioning that after the filter screen and pipe fittings are pressed together, the pipe fittings are transported to the sealing component 5 by a robotic arm for sealing at both ends. The sealing process here is the same as the existing sealing process, so it will not be described in detail. In particular, after one end of the pipe fitting is sealed, the robotic arm grabs the pipe fitting and rotates it 180° so that the other end of the pipe fitting faces the sealing component, and then both ends of the pipe fitting can be sealed by the same sealing component.

[0084] This invention is not limited to the preferred embodiments described above. Anyone can derive other forms of products under the guidance of this invention. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
