Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of integrated joint processing, and in particular to an efficiency-enhanced integrated joint quick-clip connection assembly method and system. Background Art
[0002] The one-piece joint is a very common connection structure in modern electrical, mechanical and hydraulic systems. It usually consists of a central pipe and joints at both ends. The joint needs to be pressed together with the pipe to ensure the stability of the connection between the joint and the pipe.
[0003] At present, the quick crimping connection of one-piece joints is mainly achieved by a crimping machine. The crimping machine is usually composed of a crimping mechanism, a hydraulic system and an electrical control system. The electrical control system controls the hydraulic system as a power to make the crimping mechanism push the fastener to punch the pipe wall of the joint.
[0004] However, during the current crimping process of integrated connectors, it is necessary to manually put the connector on the pipe and insert the connector and the pipe into the crimping machine. This has the following disadvantages: low efficiency: the manual splicing, handling, and positioning steps are cumbersome, becoming a bottleneck for speeding up the production line; poor consistency: manual operation can easily introduce alignment deviations between the pipe clamp and the pipe, resulting in uneven crimping or sealing failure; low degree of automation: it relies on manual intervention, is difficult to integrate into an efficient continuous production line, and increases labor costs and safety risks.
[0005] Based on the above shortcomings, at present, the continuous fiber reinforced polyethylene composite pipe hot prefabricated crimping joint and method disclosed in Publication No. CN119036871 B can be provided with a docking correction piece, and the end of the composite pipe to be crimped is placed on the inner side of the movable chain, and the end face of the composite pipe is made to fit with the rectangular blocking rod. Then, the rotating ring is rotated, and the rotation of the rotating ring causes the clamping plate to clamp and limit the composite pipe, thereby achieving the accuracy of the docking between the composite pipe and the professional joint. At the same time, the socket of the composite pipe and the professional joint is exactly located below the crimping plate. By providing a shifting and adjusting piece, after the composite pipe and the joint are limited, the two-way screw is rotated, and the two limit sliders on the two-way screw are moved toward each other by the rotation of the two-way screw, so as to know the overlapping length of the composite pipe and one end of the joint, thereby accurately adjusting the connection length of the composite pipe and the joint. Although the positioning and length adjustment during the crimping process are optimized, it fails to break through the fundamental limitation of "manual pre-assembly". The increase in its structural complexity may even further reduce the convenience of operation. Therefore, there is an urgent need for a crimping connection system that can completely eliminate the manual pre-installation process and realize full process automation to solve the core contradiction between efficiency, precision and automation integration. In view of this, in-depth research on the above issues has led to the emergence of this case. Summary of the Invention

[0023] An efficient integrated connector quick crimping connection assembly method comprises the following steps:
[0024] Step 1: The installation tube is moved to the starting position via a linear conveyor.

The conveyor belt moves the installation tube to the crimping station in a step-by-step manner, and the pressure sensor provides real-time feedback on the positioning status.
[0025] Step 2: Synchronous feeding of pipe clamps: The stepper motor drives the indexer to rotate synchronously through the flange coupling, and the rolling assembly accurately rotates the workstation angle; the pipe clamps of the linear feeder are controlled by the baffle interlock to fall into the positioning groove of the slotted plate, and the indexing plate and the conveyor belt workstation are axially coaxially aligned;
[0026] Step 3: Automatically connect the pipe clamp: The pneumatic clamp grabs the pipe clamp and moves it radially along the lever. The conical guide head is inserted into the end of the mounting pipe to form a primary positioning. The clamp inserts the pipe clamp into the mounting pipe along the conical surface of the insert. The two-stage guide system ensures that the coaxiality error is ≤0.05mm.
[0027] Step 4 Triple mechanical locking: The photoelectric sensor triggers the telescopic cylinder to push the inner tube downward, the guide rod compresses the limit spring to generate travel, the guide column of the mounting plate is inserted into the port of the mounting tube, and the guide block positioning cone is inserted into the inner hole of the pipe clamp to form an axial-radial-circumferential triple lock;
[0028] Step 5: Crimp execution and reset:
[0029] Step 5.1: Initially compress the spring to engage the tapered groove with the tapered surface of the guide block;
[0030] Step 5.2: The conical surfaces are fully engaged in the final pressure stage, generating a radial force component that drives the fastener to synchronously contract centripetally and press the pipe clamp together;
[0031] Step 5.3 After the crimping is completed, the hydraulic cylinder returns and the spring releases energy to push the inner and outer tubes back to their original position and away from the workpiece;
[0032] Step 6: Finished product step-by-step unloading: The conveyor belt moves the crimped components to the unloading station step by step. The indexer rotates synchronously to prepare new pipe clamps. After the pressure sensor confirms that the workpiece has been removed, the system automatically enters the next cycle.
[0033] Beneficial effects
[0034] The present invention provides a method and system for assembling a one-piece quick-crimping joint that improves efficiency. This method and system achieves the following beneficial effects: Through mechanical hard synchronization, the system achieves precise matching between pipe clamp supply and workpiece delivery. A two-stage guide mechanism eliminates manual alignment deviations. The tapered meshing design converts axial thrust into uniform radial pressure, ensuring consistent crimping quality. Fully automated and integrated processes reduce manual intervention, significantly shortening the single-piece operation cycle compared to traditional methods, significantly improving production efficiency and product qualification rates. The system and method also include the following specific beneficial effects.
[0035] 1. Efficiency improvement and beat optimization:
[0036] Based on the flange hard connection structure of the drive shaft and indexer, millisecond-level synchronous response of pipe clamp supply and workpiece transportation is achieved. The three processes of V-shaped straightening guide pre-positioning, pneumatic clamp automatic socketing, and hydraulic crimping operate in parallel, eliminating the time-consuming links of traditional manual handling, positioning, and clamping. After verification by the production line, the single-piece operation cycle is shortened from 25 seconds in manual mode to 8 seconds, and the overall efficiency of the production line is improved by 300%. The synchronous unloading design makes the equipment's idle time close to zero.
[0037] 2. Quality and accuracy assurance mechanism:
[0038] The innovative two-stage positioning system, conical guide head + fastening plate guide column, achieves 0.05mm coaxial accuracy between the pipe clamp and the connecting pipe, completely eliminating the problem of uneven crimping caused by manual alignment deviation. The conical surface engagement mechanism uses a 15° cone angle design to convert the axial thrust of the hydraulic cylinder into 12 sets of synchronous radial contraction force of fasteners. The difference in circumferential compression is controlled within ±0.1mm, the sealing failure rate is reduced from 8% of the traditional process to 0.2%, and the product tensile strength is increased by 25%.
[0039] 3.Automated integration and flexible production:
[0040] The PLC bus system integrates multi-dimensional data streams such as photoelectric sensing, pressure feedback, and position monitoring to achieve "perception-decision-execution" closed-loop control. The quick-change flange structure enables the replacement of mounting plates within 2 minutes. Combined with the 0.02mm-level precision compensation capability of the fine-tuning mechanism, it supports seamless switching of connectors of various specifications. Only a few people are required to monitor and operate the entire line, which reduces manpower requirements compared to traditional production lines. At the same time, it eliminates safety hazards of manual operation and provides underlying technical support for the construction of smart factories. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0052] See also Figure 1-9 The present invention provides an implementation scheme: During the current crimping process of an integrated joint, it is necessary to manually sleeve the joint onto the pipe and insert the joint and the pipe into a crimping machine. This has the following disadvantages: low efficiency: the manual sleeve connection, transportation, and positioning steps are cumbersome, becoming a bottleneck for speeding up the production line; poor consistency: manual operation easily introduces alignment deviation between the pipe clamp and the pipe, resulting in uneven crimping or sealing failure; low degree of automation: reliance on manual intervention makes it difficult to integrate into an efficient continuous production line, and increases labor costs and safety risks.
[0053] Example 1: According to the instructions attached Figure 1-9 It can be seen that in order to solve the above problems, the present application discloses an integrated joint quick-clip connection assembly system with improved efficiency, including a support frame 1, which is a rectangular structure frame. The frame is welded with high-strength steel and internally welded cross ribs to form a stable load-bearing structure.
[0054] A linear conveyor 2 is provided on the support frame 1, and the conveyor is supported by a support leg 24 installed on the support frame 1. Anchor bolts can be provided at the bottom of the support leg 24 to achieve height calibration. The transmission roller 25 installed on the support leg 24 forms a torque transmission connection with the reducer 23 through belt transmission. The conveyor belt 26 sleeved on the transmission roller 25 is made of polyurethane and has anti-slip texture.
[0055] According to the instruction manual Figure 1-9 It can be seen that the linear conveyor 2 is driven by a stepper motor 21, the output shaft of the stepper motor 21 is connected to the input end of the reduction gearbox through a coupling, and the output end of the reduction gearbox is rigidly connected to the drive shaft 27 through multi-stage gear transmission to form a power transmission chain.
[0056] A pair of alignment guides 5 are provided on both sides of the starting end of the linear conveyor 2. The V-shaped adjustable structure of the guide can realize spacing adjustment through the existing screw mechanism. The inner guide rail surface is inlaid with a wear-resistant plastic slider. Several processing stations 22 are evenly arranged on the linear conveyor 2. Several processing stations 22 match the diameter of the installation pipe to facilitate positioning of the installation pipe. The inner side of the guide forms a guiding match with the outer end of the installation pipe to ensure that the installation pipe remains centered after entering the processing station 22.
[0057] According to the instruction manual Figure 1-9 It can be seen that a pair of feeding structures 3 and a pair of pressing structures 4 are symmetrically distributed on both sides of the conveyor, wherein the feeding structure 3 corresponds to the upstream processing station 22, and the pressing structure 4 is located at the adjacent downstream station.
[0058] Specifically, the feeding structure 3 includes a rolling assembly 31, which is a disc structure arranged on the support frame 1. The central shaft 312 of the rolling assembly 31 is supported by a tapered roller bearing for rotation. The indexer 32 connected to the rolling assembly 31 is fixed to the end of the shaft 312 through gear matching. There are no less than four placement stations 33 radially arranged on the surface of the rolling assembly 31. The gear structure of the indexer 32 ensures that during the movement interval of a pair of adjacent processing stations 22, the stepper motor 21 can drive the rolling assembly 31 to rotate an angle of an adjacent placement station 33 to form intermittent motion matching, and when the stepper motor 21 stops, it also stops quickly.
[0059] According to the instruction manual Figure 1-9 It can be seen that the stepped positioning groove opened at the placement station 33 matches the outer contour of the pipe clamp. The specific placement station 33 is kept coaxially aligned with the processing station 22 of the linear conveyor 2 through laser calibration. The drive shaft 27 of the stepper motor 21 outputs torque through the reduction gearbox. The end of the drive shaft 27 is connected to the input shaft of the indexer 32 through a flange bolt. The positioning pin is set on the end face of the flange to ensure coaxial accuracy, forming a mechanical hard synchronization system to achieve consistency in loading the installation pipe and the pipe clamp.
[0060] Furthermore, the supporting shaft seat 311 of the above-mentioned rolling assembly 31 is fixed to the supporting frame 1 by high-strength bolts, and the rotating shaft 312 is assembled in the vertical groove opened on the shaft seat. The top of the rotating shaft 312 is connected to the fixed slot disk 313, and the linear feeder 314 is tangentially arranged on one side of the slot disk 313. Its outlet baffle is linked to the rotation of the dividing disk through a cam mechanism to ensure that the pipe clamp falls into the work position accurately.
[0061] According to the instruction manual Figure 1-9 As can be seen, the crimping structure 4 includes a crimping frame 41, which is vertically mounted on the support shaft seat 311 via a bolt assembly. The crimping telescopic tube 42 provided on the crimping frame 41 comprises an inner tube 421 and an outer tube 425, forming a composite structure. The inner tube 421 forms a sliding fit with the crimping frame 41 via two chrome-plated guide rods 422, with a limit spring 423 installed between the end of the guide rods 422 and the crimping frame 41; the outer tube 425 is coaxially sleeved on the outside of the inner tube 421.
[0062] The truncated cone-shaped mounting plate 43 provided in the mounting expansion tube 42 is connected to the head end flange of the inner tube 421 through positioning pins and bolts. The diameter of the guide socket 431 opened in the center of the mounting plate 43 is larger than the maximum pipe clamp size. The mounting plate 43 is circumferentially milled with a number of mounting grooves 432. The surface-hardened guide block 44 is assembled in the mounting groove 432. The conical surface of the outer side of the guide block 44 is consistent with the cone angle of the mounting plate 43.
[0063] Furthermore, the end face of the guide block 44 forms a plug-in fit with the boss of the fastener 45 and is fastened by an internal screw. The axis of the buckling telescopic tube 42 maintains a coaxial alignment with the downstream processing station 22 of the linear conveyor 2. The buckling controller 46 connected to one side forms a force transmission mechanism with the lever 471 through a hinged support. A pneumatic clamp is installed on the paddle 472 at the end of the lever 471. The V-shaped bayonet of the clamp matches the outer diameter of the pipe clamp. The split connection between the buckling plate 43 and the buckling telescopic tube 42 is achieved by a quick-release flange, and positioning pin holes are evenly distributed around the circumference of the flange.
[0064] The inner tube 421 of the buckling telescopic tube 42 forms a precision sliding pair with the buckling frame 41 through the guide rod 422. The limit spring 423 sleeved on the guide rod 422 provides an initial reset force. The flange plate welded at the head end of the inner tube 421 is positioned and connected to the buckling plate 43 through the stopper. The inner conical surface of the conical groove 427 machined at the end of the outer tube 425 and the outer conical surface of the guide block 44 form a pressure transmission interface.
[0065] When the buckling action is executed, the buckling controller 46 first pushes the inner tube 421 to slide along the guide rod 422. The spring at the top of the guide rod 422 is compressed to produce a stroke, so that the guide column in the center of the buckling plate 43 is inserted into the positioning hole on the end face of the mounting tube. The outer tube 425 continues to advance under the drive of the telescopic cylinder 461. The two-section spring 426 between the outer tube 425 and the inner tube 421 is compressed. At this time, the inner conical surface of the conical groove 427 gradually engages with the outer conical surface of the guide block 44. As the outer tube 425 continues to advance, the radial component force generated by the engagement of the conical surfaces forces the guide block 44 to slide centripetally along the mounting groove 432, driving the fastener 45 to synchronously radially contract and press the pipe clamp. After the crimping is completed, the hydraulic cylinder returns, and the spring releases energy to push the outer tube 425 to reset. The inner tube 421 synchronously retreats and detaches from the workpiece under the action of the spring on the guide rod 422.
[0066] According to the instruction manual Figure 1-9 It can be seen that the double-acting telescopic cylinder 461 of the above-mentioned buckling controller 46 is connected to the control guide block 462 through a threaded connection, the control guide block 462 limits the motion trajectory through a linear guide rail, the shift rod 471 welded to the control guide block 462 forms a linkage with the shift piece 472, and the conical guide head at the front end of the shift assembly 47 and the guide column in the center of the buckling plate 43 form a two-stage positioning system, and the distance between the two-stage guide surfaces is set to a specific proportion of the length of the pipe clamp.
[0067] The fine-tuning component 48 is equipped with a slider in a rectangular guide rail set inside the inner tube 421. The slider is connected to the adjusting screw 482 through the threaded hole 442. A handwheel with a scale ring is installed at the end of the screw. When the handwheel is rotated, the slider is pushed to move through the threaded transmission, and the radial position of the fine-tuning buckle plate 43 is compensated for the wear gap.
[0068] According to the instructions attached Figure 1-9 It can be seen that the photoelectric sensor 6 installed on the support frame 1 corresponding to the crimping station is connected to the control system through a shielded cable. The control box 7 is fixed to the side of the support frame 1 through a mounting plate. The built-in PLC in the control box 7 coordinates each execution unit through the industrial bus. The conveyor belt 26 of the linear conveyor 2 has a vulcanized anti-slip convex pattern on its surface, and the pressure sensor embedded at the bottom of the station plate monitors the status of the workpiece in real time.
[0069] When the system is running, the linear conveyor 2 is driven by the stepper motor 21 to transfer the mounting tube to the processing station 22, and the V-shaped guide rail of the straightening guide 5 automatically corrects the position of the workpiece. The stepper motor 21 drives the indexer 32 to rotate synchronously through the drive shaft 27, so that the pipe clamp station on the slot plate 313 is accurately aligned with the conveyor belt station. After the pneumatic clamp of the toggle component 47 grabs the pipe clamp, it is inserted into the end of the mounting tube under the guidance of the conical plug block 474. The photoelectric sensor 6 triggers the crimping program after detecting the positioning signal: the inner tube 421 first moves down to complete the workpiece positioning, and the outer tube 425 is then pushed forward to drive the fastener 45 to radially press through the conical surface engagement to ensure consistent crimping accuracy each time. The entire process realizes continuous operation of synchronous feeding, synchronous positioning, and synchronous crimping through synchronous mechanical linkage. The conical surface engagement mechanism converts axial motion into uniform radial pressure, and the quick-change structure supports rapid switching of production of products of multiple specifications.
[0070] Example 2: In order to cooperate with the application of the above system, the present application also discloses an efficient one-piece connector quick buckle connection assembly method, comprising the following steps:
[0071] Step 1: The installation tube is moved to the starting position via a linear conveyor. The V-shaped guide rail of the alignment guide automatically corrects the installation tube's position deviation with a positioning accuracy of ±0.1mm. The conveyor belt moves the installation tube to the crimping station in a step-by-step manner, and the pressure sensor provides real-time feedback on the positioning status.
[0072] Step 2: Synchronous feeding of pipe clamps: The stepper motor drives the indexer to rotate synchronously through the flange coupling, and the rolling assembly accurately rotates the workstation angle; the pipe clamps of the linear feeder are controlled by the baffle interlock to fall into the positioning groove of the slotted plate, and the indexing plate and the conveyor belt workstation are axially coaxially aligned;
[0073] Step 3: Automatically connect the pipe clamp: The pneumatic clamp grabs the pipe clamp and moves it radially along the lever. The conical guide head is inserted into the end of the mounting pipe to form a primary positioning. The clamp inserts the pipe clamp into the mounting pipe along the conical surface of the insert. The two-stage guide system ensures that the coaxiality error is ≤0.05mm.
[0074] Step 4 Triple mechanical locking: The photoelectric sensor triggers the telescopic cylinder to push the inner tube downward, the guide rod compresses the limit spring to generate travel, the guide column of the mounting plate is inserted into the port of the mounting tube, and the guide block positioning cone is inserted into the inner hole of the pipe clamp to form an axial-radial-circumferential triple lock;
[0075] Step 5: Crimp execution and reset:
[0076] Step 5.1: Initially compress the spring to engage the tapered groove with the tapered surface of the guide block;
[0077] Step 5.2: The conical surfaces are fully engaged in the final pressure stage, generating a radial force component that drives the fastener to synchronously contract centripetally and press the pipe clamp together;
[0078] Step 5.3 After the crimping is completed, the hydraulic cylinder returns and the spring releases energy to push the inner and outer tubes back to their original position and away from the workpiece;

An efficient integrated connector quick-connection assembly method, applied to an efficient integrated connector quick-connection assembly system according to any one of claims 1 to 8, characterized in that: The method includes the following steps: Step 1: The installation tube is moved to the starting position via a linear conveyor. The V-shaped guide rail of the alignment guide automatically corrects the installation tube's position deviation with a positioning accuracy of ±0.1mm. The conveyor belt moves the installation tube to the crimping station in a step-by-step manner, and the pressure sensor provides real-time feedback on the positioning status. Step 2: Synchronous feeding of pipe clamps: The stepper motor drives the indexer to rotate synchronously through the flange coupling, and the rolling assembly accurately rotates the workstation angle; the pipe clamps of the linear feeder are controlled by the baffle interlock to fall into the positioning groove of the slotted plate, and the indexing plate and the conveyor belt workstation are axially coaxially aligned; Step 3: Automatically connect the pipe clamp: The pneumatic clamp grabs the pipe clamp and moves it radially along the lever. The conical guide head is inserted into the end of the mounting pipe to form a primary positioning. The clamp inserts the pipe clamp into the mounting pipe along the conical surface of the insert. The two-stage guide system ensures that the coaxiality error is ≤0.05mm. Step 4 Triple mechanical locking: The photoelectric sensor triggers the telescopic cylinder to push the inner tube downward, the guide rod compresses the limit spring to generate travel, the guide column of the mounting plate is inserted into the port of the mounting tube, and the guide block positioning cone is inserted into the inner hole of the pipe clamp to form an axial-radial-circumferential triple lock; Step 5: Crimp execution and reset: Step 5.1: Initially compress the spring to engage the tapered groove with the tapered surface of the guide block; Step 5.2: The conical surfaces are fully engaged in the final pressure stage, generating a radial force component that drives the fastener to synchronously contract centripetally and press the pipe clamp together; Step 5.3 After the crimping is completed, the hydraulic cylinder returns and the spring releases energy to push the inner and outer tubes back to their original position and away from the workpiece; Step 6: Finished product step-by-step unloading: The conveyor belt moves the crimped components to the unloading station step by step. The indexer rotates synchronously to prepare new pipe clamps. After the pressure sensor confirms that the workpiece has been removed, the system automatically enters the next cycle.
