Description

Technical Field

[0001] This invention relates to the field of clamp assembly technology, and more specifically, to a multi-stage clamp integrated assembly machine. Background Technology

[0002] Pipe clamps, as a commonly used pipe connection fastener, are widely used in various fluid transport systems such as hydraulic, pneumatic, water supply, and HVAC systems. Their structure typically includes an upper clamp body and a lower clamp body, which are connected and fastened using bolts or screws. In mass production, the assembly efficiency and accuracy of clamps directly affect product quality and production costs.

[0003] Multi-level clamps are a general term for a series of clamps applicable to various specifications and grades.

[0004] In existing technologies, clamp assembly is mostly completed manually or with semi-automated equipment. Manual assembly is labor-intensive, inefficient, and prone to inconsistent assembly quality due to inconsistent operation. Some existing automated assembly equipment often uses vibratory feeders in conjunction with robotic arms to achieve material feeding and assembly, but the following problems still exist:

[0005] The feeding posture of the upper and lower components of the clamp is strictly required. In particular, the upper clamp body is usually an arc-shaped structure, which is prone to rolling, tipping or jamming during the conveying process, affecting the continuity and stability of feeding.

[0006] Different specifications and sizes of clamps require different tooling or fixtures, making changes and adjustments complicated and resulting in poor equipment versatility;

[0007] During assembly, the positioning of the lower clamp body at the assembly station often relies on a fixed limiting structure, which is difficult to adapt to the precise positioning of clamps of various specifications, and is prone to deviation and tilting, affecting the subsequent screw assembly quality.

[0008] The alignment and assembly process of the upper and lower components lacks coordination, often requiring multiple workstations to complete the process step by step, which occupies a large area and has a long cycle time.

[0009] Therefore, we have made improvements to this and proposed a multi-level clamp integrated assembly machine. Summary of the Invention

[0010] The purpose of this invention is to provide a multi-level clamp assembly machine to solve the problems of unstable upper clamp posture, difficulty in changing multiple specifications, low positioning accuracy, and poor process coordination in the clamp assembly process of the prior art, so as to realize fully automatic, high-efficiency, and high-precision clamp assembly.

[0011] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0012] A multi-stage clamp integrated assembly machine is proposed to improve the above-mentioned problems.

[0013] The application is as follows:

[0014] A multi-stage clamp assembly machine includes an assembly line, a first feeding line for conveying the upper clamp body, and a second feeding line for conveying the lower clamp body, and further includes:

[0015] The first connecting assembly is used to transport the upper hoop from the initial lying state to the standing state from the first feeding line to the assembly line. The first connecting assembly includes a flipping assembly for driving the upper hoop to flip and an inclined slot for facilitating flipping operation. The flipping assembly includes an upper lever for driving the center position of the arc end of the upper hoop to rotate upward and a lower lever for pressing down the two mounting ends of the upper hoop respectively. A linkage assembly for linkage between the upper lever and the lower lever is provided. The linkage assembly includes a linkage rope and a connecting rope track for linkage between the upper lever and the lower lever, and a threaded cylinder and a threaded rod for driving the upper lever to move up and down.

[0016] The second connecting assembly is used to transport the lower hoop from the second feeding line to the assembly line. The second connecting assembly includes a feeding assembly that drives the lower hoop to move down to the assembly line and a limiting assembly that drives the multi-level specification clamps to be positioned on the assembly line. The feeding assembly includes a second feeding hopper and an inclined chute connected to the outlet of the second feeding line and the inlet of the assembly line.

[0017] As a preferred technical solution of this application, the flipping assembly further includes a rotating ring located at the outer end of the upper paddle for driving the upper paddle to rotate and a gear groove embedded at the outer end of the rotating ring. The outer end of the gear groove is provided with a linkage gear for driving the rotating ring to rotate, and a micro motor is provided in the center of the linkage gear and embedded in the first connecting assembly.

[0018] As a preferred technical solution of this application, the upper end of the upper lever is provided with two sets of arc-shaped blocks. The outer end of the arc-shaped blocks is wrapped with an annular groove, which is embedded in the lower inner surface of the threaded cylinder. Two sets of positioning plates are also fixed in the annular groove. The two sets of positioning plates and the two sets of arc-shaped blocks are in contact with each other respectively. The positioning plates and arc-shaped blocks are arranged in pairs in an equally spaced annular array in the annular groove. A linkage spring is provided between the positioning plates and the arc-shaped blocks. The threaded cylinder moves up and down along the threaded rod, and the upper end of the threaded rod is provided with a linkage motor for driving rotation.

[0019] As a preferred technical solution of this application, the upper paddle moves up and down within the first connecting assembly, which is restricted by the connecting rope track. When the upper paddle moves upward, the gear groove and the linkage gear disengage from each other. When the upper paddle moves to the bottom of the connecting rope track, the gear groove and the linkage gear are engaged by the rebound of the linkage spring.

[0020] As a preferred technical solution of this application, the connecting rope track is divided into two parts at the center of the threaded rod and extends outward to the slide groove. The linkage rope is provided with two sets of parallel lines fixed on the threaded cylinder, and the other end of the linkage rope is fixed on the lower lever.

[0021] As a preferred technical solution of this application, the lower lever slides up and down along the slide groove, and a limiting spring is provided between the lower end of the lower lever and the slide groove. During the upward movement of the upper lever, the lower lever moves downward, pushing the two mounting ends of the upper hoop downward.

[0022] As a preferred technical solution of this application, the limiting component includes a pressing structure and a limiting structure. The limiting structure includes a limiting block, a limiting rod, a positioning spring, and a limiting groove located at both ends of each assembly port on the assembly line. The positioning spring is wrapped around the outer end of the limiting rod, and the limiting groove is wrapped around the outer end of the limiting rod. The limiting grooves are evenly spaced and arranged perpendicular to the transport direction of the assembly line. The limiting block is tightly fitted to both ends of the lower hoop that enters the assembly port.

[0023] As a preferred technical solution of this application, the pressing structure is used to press the lower hoop body that enters the assembly port downward and corresponds to the limiting structure. The pressing structure includes a linkage seat fixed to the upper end of the second feeding hopper and a telescopic rod and a rubber hammer installed at the front end of the linkage seat for pressing the lower hoop body. The rubber hammer is in contact with the center of the inner arc surface of the lower hoop body.

[0024] As a preferred technical solution of this application, the lower outlet of the inclined chute corresponds to the first feed port in the assembly line during operation, and the lower outlet of the inclined chute corresponds to the second feed port in the assembly line during operation.

[0025] As a preferred technical solution of this application, each assembly port has a positioning mounting block at its inner end, and the positioning mounting block is located at the four corners of each assembly port for multi-level clamps to run and assemble screw components in the assembly line.

[0026] As a preferred technical solution of this application, a controller is provided between the telescopic rod and the linkage motor. After the rubber hammer at the lower end of the telescopic rod comes into contact with the lower hoop body to be assembled and loaded, the command is transmitted to the linkage motor to push the upper hoop body to be loaded into the inclined slot. When the lower hoop body, which has been limited by the limiting structure, moves to the outlet end of the inclined slot, the upper hoop body to be loaded is already in a standing position and slides into the upper end of the corresponding lower hoop body.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] In the scheme of this application:

[0029] 1. By setting the first connecting component, the upper and lower levers in the flipping component are linked to smoothly flip the flat conveying upper hoop into an upright position, and guide it into the assembly line through the inclined slot. This effectively solves the problem of easy rolling and jamming of arc-shaped parts during the conveying process, improves the success rate and continuity of feeding, and is conducive to the automatic flipping and stable conveying of the upper hoop.

[0030] 2. By setting the limit component, adopting the elastically adjustable limit block structure, and with the pressing action of the push structure, it can automatically center and press the lower hoop of different widths, ensuring that its position in the assembly port is accurate and stable, which greatly improves the versatility of the equipment and the replacement efficiency of multi-level clamps.

[0031] 3. By linking the pressing action of the second connecting component with the flipping feeding action of the first connecting component through the controller, it is ensured that after the lower hoop is positioned, the upper hoop is synchronously conveyed and aligned with it in an upright state for assembly. The degree of automation is high and the assembly efficiency is significantly improved.

[0032] 4. The linkage assembly, consisting of a linkage rope, a connecting rope track, a threaded cylinder, and a threaded rod, enables the synchronous and precise movement of the upper lever rising and the lower lever falling. The clutch design of the gear groove and the linkage gear ensures that the flipping action is triggered only at the required position, and the mechanism operates stably and reliably.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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.

[0052] Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely to illustrate some embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments, features, and technical solutions in the embodiments of the present invention can be combined with each other.

[0053] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0054] like Figure 1 - Figure 3 As shown, this embodiment proposes a multi-stage clamp integrated assembly machine, including an assembly line 1, a first feeding line 2 for conveying the upper clamp body, and a second feeding line 3 for conveying the lower clamp body, and further including:

[0055] Specifically, when it is necessary to first feed the lower hoop into the assembly opening of assembly line 1, such as... Figure 13 and Figure 16 As shown, in a preferred embodiment, based on the above method, the second connecting component 5 is further used to transport the lower hoop from the second feeding line 3 to the assembly line 1. The second connecting component 5 includes a feeding component that drives the lower hoop to move down to the assembly line 1 and a limiting component 6 that drives the multi-level specification clamps to be positioned on the assembly line 1. The feeding component includes a second feeding hopper 51 and an inclined chute 52 connected to the outlet of the second feeding line 3 and the inlet of the assembly line 1.

[0056] The limiting component 6 includes a pressing structure and a limiting structure. The limiting structure includes a limiting block 61, a limiting rod 62, a positioning spring 63, and a limiting groove 64 located at both ends of each assembly port of the assembly line 1. The positioning spring 63 is wrapped around the outer end of the limiting rod 62, and the limiting groove 64 is wrapped around the outer end of the limiting rod 62. The limiting groove 64 is evenly spaced and arranged perpendicular to the transport direction of the assembly line 1. The limiting block 61 is tightly fitted to both ends of the lower hoop that enters the assembly port.

[0057] The pressing structure is used to press the lower hoop body into the assembly port downwards and corresponds to the limiting structure. The pressing structure includes a linkage seat 53 fixed to the upper end of the second feeding hopper 51, and a telescopic rod 54 and a rubber hammer 55 installed at the front end of the linkage seat 53 for pressing the lower hoop body. The rubber hammer 55 is in contact with the center of the inner arc surface of the lower hoop body.

[0058] The lower outlet of the inclined chute 52 corresponds to the first feed port of the assembly line 1 during operation, and the lower outlet of the inclined chute 42 corresponds to the second feed port of the assembly line 1 during operation.

[0059] Each assembly port has a positioning mounting block 7 at its inner end, and the positioning mounting block 7 is located at the four corners of each assembly port for multi-level clamps to run and assemble screw components in the assembly line 1.

[0060] The lower clamp body enters the initial assembly port of the assembly line 1 through the inclined groove 52 via the operation of the second connecting component 5. At this time, the lower clamp body is not completely fixed to the assembly port. It may simply be suspended above the limit blocks 61 at both ends, or the connection with the limit blocks 61 at both ends may not be complete, and the limiting effect may not be perfect. This is not conducive to fixing clamps of different specifications during assembly. At this time, the telescopic rod 54 (such as an electric cylinder) connected to the linkage seat 53 drives the rubber hammer 55 to move downward, squeezing the lower clamp body to be evenly positioned at both ends by the limit blocks 61. The four corners of the lower end of the lower clamp body contact each other with the positioning mounting blocks 7. When installing the screw assembly later, the threaded assembly can be installed through the two adjacent positioning mounting blocks 7 without restriction.

[0061] During this process, after the telescopic rod 54 presses the rubber hammer 55 downwards, it sends a completion limit command to the first feeding line 2, causing the control module in the first feeding line 2 to drive the operation of the first feeding line 2 and the operation of the micro motor and the linkage motor 412.

[0062] Specifically, such as Figure 3 - Figure 12 As shown, in a preferred embodiment, based on the above method, the first connecting component 4 is used to transport the upper hoop from the initial lying state to the standing state from the first feeding line 2 to the assembly line 1. The first connecting component 4 includes a flipping component for driving the upper hoop to flip and an inclined slot 42 for facilitating flipping operation. The flipping component includes an upper lever 43 for driving the center position of the arc end of the upper hoop to rotate upward and a lower lever 414 for pressing down the two mounting ends of the upper hoop respectively. A linkage component for linkage movement is provided between the upper lever 43 and the lower lever 414. The linkage component includes a linkage rope 413 and a connecting rope track 415 for linkage between the upper lever 43 and the lower lever 414, a threaded cylinder 410 and a threaded rod 411 for driving the upper lever 43 to move up and down.

[0063] The flipping assembly also includes a rotating ring 44 located at the outer end of the upper paddle 43 to drive the upper paddle 43 to rotate, and a gear groove 45 embedded at the outer end of the rotating ring 44. The outer end of the gear groove 45 is provided with a linkage gear 46 to drive the rotating ring 44 to rotate, and a micro motor is provided in the center of the linkage gear 46 and embedded in the first connecting assembly 4.

[0064] The upper end of the upper lever 43 is provided with two sets of arc-shaped blocks 49. The outer end of the arc-shaped blocks 49 is wrapped with an annular groove 48. The annular groove 48 is embedded in the inner surface of the lower end of the threaded cylinder 410. Two sets of positioning plates are also fixed in the annular groove 48. The two sets of positioning plates and the two sets of arc-shaped blocks 49 are in contact with each other. The positioning plates and the arc-shaped blocks 49 are arranged in pairs in an equally spaced annular array in the annular groove 48. A linkage spring 47 is provided between the positioning plates and the arc-shaped blocks 49. The threaded cylinder 410 moves up and down along the threaded rod 411. The upper end of the threaded rod 411 is provided with a linkage motor 412 for driving rotation.

[0065] The upper paddle 43 moves up and down within the first connecting assembly 4, which is restricted by the connecting rope track 415. When the upper paddle 43 moves upward, the gear groove 45 disengages from the linkage gear 46. When the upper paddle 43 moves to the bottom of the connecting rope track 415, the gear groove 45 is pushed to mesh with the linkage gear 46 by the rebound of the linkage spring 47.

[0066] The connecting rope track 415 is divided into two at the center of the threaded rod 411 and extends outward to the slide groove 416. The linkage rope 413 has two sets of parallel lines fixed on the threaded cylinder 410, and the other end of the linkage rope 413 is fixed on the lower lever 414.

[0067] The lower lever 414 slides up and down along the slide groove 416, and a limiting spring 417 is provided between the lower end of the lower lever 414 and the slide groove 416. During the upward movement of the upper lever 43, the lower lever 414 moves downward, pushing the two mounting ends of the upper hoop downward.

[0068] After the first feeding line 2 receives the lower hoop and completes its positioning, it will drive the control module of the first feeding line 2 to control the operation of the first feeding line 2, the micro motor, and the linkage motor 412. At this time, the micro motor drives the rotating ring 44 connected to the linkage gear 46 and the gear groove 45 to rotate, thereby driving the upper lever 43 to rotate and enter the lower side of the arc-shaped end of the upper hoop. At this time, the lower levers 414 at both ends also come into contact with the upper surfaces of the corresponding mounting ends of the upper hoop. At this time, the linkage motor 412 operates, and the linkage rope 413... When connected, the upper lever 43 moves upward and the lower lever 414 moves downward, moving the lying upper hoop from a lying state to an upright state. During this process, the upper hoop is also moved forward by the movement of the first feeding line 2, and comes into contact with the inclined slot 42 in the first unloading hopper 41, thereby assisting in pushing it to stand up. The size of the inclined slot 42 gradually decreases, thereby ensuring that the upper hoop stands up successfully and comes into contact with the lower hoop that has completed the limit. It then moves to the next tooling through the assembly line 1 for fixing and assembling the screw assembly.

[0069] A controller is provided between the telescopic rod 54 and the linkage motor 412. After the rubber hammer 55 at the lower end of the telescopic rod 54 comes into contact with the lower hoop body to be assembled and loaded, the command is transmitted to the linkage motor 412 to push the upper hoop body to be loaded into the inclined slot 42. When the lower hoop body that has been limited by the limiting structure moves to the outlet end of the inclined slot 42, the upper hoop body to be loaded is in a standing position and slides into the upper end of the corresponding lower hoop body.

[0070] Furthermore, the straight end of the inclined slot 42 can move left and right to facilitate the feeding of upper hoop bodies of different specifications. When the straight end of the inclined slot 42 moves, it will drive the length of the linkage rope 413 to change.

[0071] Through the above steps, the upper hoop and lower hoop can be easily fed separately, and the tilting of the upper hoop or lower hoop caused by the vertical transportation process is avoided, which would affect the assembly efficiency.

[0072] Meanwhile, the setting of the limiting component 6 facilitates the assembly of clamps of various specifications and grades.

[0073] The upper hoop is processed through: a flipping assembly, using an upper lever 43 and a lower lever 414 linkage design to achieve a smooth flipping of the upper hoop from lying flat to standing; a linkage mechanism: a rigid synchronization system composed of a threaded rod 411, a threaded cylinder 410, and a linkage rope 413 to ensure coordinated movement of the upper and lower levers 414; a clutch-type drive: the clutch design of the gear groove 45 and the linkage gear 46 ensures that the flipping action is triggered only at the required position, avoiding interference; and a guide structure: the inclined slot 42 adopts a tapered design to assist the upper hoop in completing the final posture shaping.

[0074] The lower hoop is processed through: feeding mechanism: the inclined chute 52 and the second feeding hopper 51 form a sliding feeding channel, which is simple in structure and highly reliable; limiting component 6: the limiting block 61 structure with spring support can adapt to lower hoops of different widths and realize automatic centering; pressing mechanism: the telescopic rod 54 cooperates with the rubber hammer 55 to realize the light pressure positioning of the lower hoop and avoid damage to the workpiece surface;

[0075] In the assembly machine, we use a control system to coordinate the assembly operation. Photoelectric sensors or displacement sensors are installed at key locations such as the assembly port, the outlet of the inclined chute 52, and the flipping station to detect the position and status of the workpiece. A PLC or industrial controller is used to receive sensor signals and coordinate the action sequence of mechanisms such as the first feeding line 2, the second feeding line 3, the flipping component, and the limit component 6. An optional touch screen is used to set clamp specifications, adjust process parameters, and display equipment status.

[0076] Specifically, as a preferred embodiment, based on the above method, further:

[0077] Operators select clamp specifications through the human-machine interface, and the control system automatically adjusts parameters such as the width of the inclined slot 42 and the initial position of the limit block 61. When changing specifications, no hardware needs to be replaced, only parameter adjustments are required, enabling rapid changeover.

[0078] The lower hoop slides from the second feeding line 3 into the assembly port via the inclined groove 52; after the photoelectric sensor detects that it is in position, the controller starts the telescopic rod 54 and the rubber hammer 55 presses down, so that the lower hoop falls between the limit block 61 and the positioning mounting block 7; after the positioning is completed, the sensor feeds back a signal to the controller.

[0079] After receiving the signal that the lower hoop has been positioned, the controller starts the first feeding line 2; the upper hoop enters the flipping station, and the micro motor drives the linkage gear 46 to make the upper lever 43 rotate to the lower arc end of the upper hoop; the linkage motor 412 starts, driving the threaded cylinder 410 to move down, and the linkage rope 413 pulls the lower lever 414 down, while the upper lever 43 pushes up, completing the flipping; the flipped upper hoop enters the inclined slot 42, and the gradually narrowing slot guides it to stand completely upright;

[0080] The upright upper clamp slides out of the inclined slot 42 and falls precisely onto the positioned lower clamp; assembly line 1 drives the assembled clamp to the next station for automatic screw assembly; after assembly, the clamp is output and the equipment enters the next cycle.

[0081] Blockage sensors are installed in key channels. Once an abnormality is detected, the machine will stop immediately and an alarm will sound. If the upper hoop fails to flip, the system can perform secondary correction using a spare lever or pneumatic push rod. A material detection sensor is installed at the end of the feeding line to prompt for additional material when the material is insufficient.

[0082] When this application is used:

[0083] First, the lower hoop enters assembly line 1. The lower hoop is output from the second feeding line 3 and slides into the first assembly port of assembly line 1 via the second unloading hopper 51 and the inclined chute 52. The lower hoop is initially placed on the limiting blocks 61 at both ends of the assembly port. At this time, the mechanism is activated, and the telescopic rod 54 drives the rubber hammer 55 to press down, pressing the lower hoop into and securing it within the positioning space formed by the limiting block 61 and the positioning mounting block 7, completing precise positioning. After the positioning action is completed, the sensor or controller inside the telescopic rod 54 sends a signal.

[0084] During the unloading of the upper hoop, after receiving a signal, the controller starts the first feeding line 2, the micro motor, and the linkage motor 412. The micro motor drives the linkage gear 46, which in turn rotates the rotating ring 44 and the upper paddle 43, causing the upper paddle 43 to move to the lower part of the arc-shaped end of the upper hoop. At the same time, the two lower paddles 414 move to the upper part of the two mounting ends of the upper hoop. The linkage motor 412 drives the threaded rod 411 to rotate, which causes the threaded cylinder 410 to move downward. Then, through the linkage rope 413, the lower paddles 414 are pulled down along the slide groove 416 to press down the two mounting ends of the upper hoop. At the same time, the upper paddle 43 pushes up the middle of its arc-shaped end under the restriction of the connecting rope track 415. Under the synergistic effect of the upper paddle 43 pushing up and the lower paddle 414 pressing down, the upper hoop gradually flips from a flat state to an upright state. During the flipping process, the first feeding line 2 continues to convey, so that the upper hoop in the flipping process enters the inclined slot 42. The width of the slanted slot 42 gradually narrows, further guiding and ensuring that the upper hoop is completely upright;

[0085] When the upper and lower clamps are assembled: when the lower clamp moves to the work position below the outlet of the inclined slot 42, the upper clamp, which has been erected, slides out from the inclined slot 42 and, relying on gravity and guidance, falls precisely on the corresponding lower clamp, achieving initial assembly; the assembled clamp assembly continues to move with assembly line 1 to the subsequent work position for automatic screw assembly and fastening.

[0086] The above process is carried out cyclically under the coordination of the controller, realizing continuous, integrated automatic assembly of the lower hoop positioning, upper hoop flipping and feeding, and the alignment and combination of the two;

[0087] The overall assembly is assisted by robots to complete errors and corrections, so as to truly free up workers' hands, realize automated operation, and increase production output;

[0088] The upper and lower hoops are conveyed separately by a dual-line feeding system. The upper hoop is used to change its posture by a flipping component, and the lower hoop is used to achieve adaptive positioning by a limiting component 6. Finally, the two are precisely assembled under the coordination of the control system.

[0089] This invention has the advantages of being fully automatic, adaptable to multiple specifications, high precision, and high efficiency, and is suitable for the batch assembly of clamps in hydraulic, pneumatic, and water supply systems.

[0090] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.
