Description

Technical Field

[0001] This invention belongs to the technical field of chain assembly equipment, specifically relating to an automated device and method for assembling half-joints on roller chains. Background Technology

[0002] In order to ensure the normal operation of roller chains, when the chain is too loose or too tight, a half-mesh connector is often used to connect the chains. For example... Figure 17 As shown, a half-link joint is a special type of transition link, comprising two mirror-image "Z"-shaped chain plates. Each "Z"-shaped chain plate includes a first connecting part that is concave inward and a second connecting part that is convex outward. The first connecting parts of the two "Z"-shaped chain plates are fixedly connected by a sleeve, with a roller fitted around the sleeve. Essentially, this forms half of an inner link, used to connect with the disassembled outer link of the chain. The second connecting parts of the two "Z"-shaped chain plates are fixedly connected by a pin, essentially forming half of an outer link, used to connect with the disassembled inner link of the chain. After connection, the problem of the chain being too loose or too tight can be effectively solved.

[0003] Due to the special shape of the half-mesh connector, it is difficult to achieve automated assembly. There is currently a lack of equipment for automated assembly of half-mesh connectors. The current assembly method mainly relies on manual labor, which has the disadvantages of low assembly efficiency, high labor intensity, safety hazards, significant human factors affecting product quality and delivery time, and poor product consistency. Summary of the Invention

[0004] This invention discloses an automated device and method for assembling half-mesh connectors on roller chains, aiming to automate the assembly of half-mesh connectors on roller chains. It can automatically assemble half-mesh connectors at one end of disassembled sleeve chains (such as 08A, 08B, 10A, 10B), significantly improving production efficiency and ensuring production quality, while avoiding the problems of high labor intensity, safety hazards, and difficulty in guaranteeing quality associated with manual operation.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] An automated device for assembling half-mesh joints of roller chains includes a machine base, a chain conveying guide rail arranged on the upper surface of the machine base in the left-right direction, and a disassembly station, a chain and half-mesh joint assembly station, a riveting station, and a chain removal station arranged sequentially on the upper surface of the machine base along the chain conveying guide rail; the chain and half-mesh joint assembly station includes a half-mesh joint conveying mechanism, a pin conveying mechanism, and an assembly mechanism.

[0007] Preferably, the chain conveyor rail is used to convey the roller chain. A drive sprocket is rotatably connected to the upper surface of the machine platform on one side of the chain conveyor rail. One end of the drive sprocket passes through the side wall of the chain conveyor rail and is engaged with the roller chain. The axle of the drive sprocket passes through the machine platform and is fixedly connected to the output shaft of a servo motor preset below the machine platform. Driven by the servo motor, the roller chain moves to the right along the chain conveyor rail to the disassembly station.

[0008] Preferably, the disassembly station includes a disassembly device located on one side of the chain conveyor guide rail. The disassembly device includes a hydraulic cylinder fixedly mounted on the machine platform via a support frame. The piston rod of the hydraulic cylinder extends downward and is fixedly connected to two disassembly pins arranged side by side at its end. The disassembly pins are used to split the roller chain at the position to be disassembled into two sections. The two removed pins and the lower outer chain plate are discharged outward along the pre-set discharge hole on the machine platform. The other removed upper outer chain plate is discharged from the chain conveyor guide rail by the air blowing mechanism. The air blowing mechanism includes an air blowing pipe opposite to the upper outer chain plate. One end of the air blowing pipe is connected to a high-pressure gas supply device. The side wall of the chain conveyor guide rail away from the air blowing pipe is provided with a groove. Under the blowing of the air blowing pipe, the upper outer chain plate is discharged along the groove. The inner single link at the end of the disassembled chain segment away from the drive sprocket constitutes an installation part for the connection of the half-mesh connector.

[0009] Preferably, the upper surface of the machine platform opposite the disassembly device is further provided with a chain positioning mechanism. The chain positioning mechanism includes a positioning fork and a first cylinder connected to the positioning fork. The cylinder barrel of the first cylinder is fixedly connected to the upper surface of the machine platform, and the piston rod end is connected to the positioning fork. The positioning fork matches the shape of the side surface of the inner single link of the roller chain and is used to insert into the side surface of the inner single link to press the roller chain tightly. A through hole is provided on one side wall of the chain conveyor guide rail for the positioning fork to pass through. A second cylinder is provided on one side of the chain positioning mechanism and directly opposite the disassembly device. The cylinder barrel of the second cylinder is fixedly connected to the upper surface of the machine platform. The piston rod of the second cylinder is connected to a first push plate and a second push plate, which are positioned opposite each other, via a joint. The head of the first push plate forms part of the side wall of the chain conveyor guide rail and is limited by the push of the second cylinder. The head of the second push plate extends towards the disassembly device and forms part of the bottom plate of the chain conveyor guide rail. The chain conveyor guide rail has a U-shaped cross-section. The side of the chain conveyor guide rail facing the second cylinder has a through hole two for the first and second push plates to pass through. The side wall of the chain conveyor guide rail opposite the first push plate has a groove for the upper outer chain plate to be discharged. The head of the second push plate has a through hole three for the pin shaft to pass through. Initially, the roller chain is positioned at the disassembly station. During disassembly, the pin shaft passes through the through hole three and is discharged through the discharge hole on the machine. The piston rod of the first cylinder rises, the second cylinder retracts, and the first and second push plates retract simultaneously. When the second push plate retracts, the discharge hole is exposed, and the lower outer chain plate is discharged from the discharge hole. The upper outer chain plate is blown out of the groove by the air pipe. Afterward, the second cylinder extends, and the first and second push plates reset. Driven by the drive sprocket, the roller chain disassembled on the left continues to move to the right, causing its head to abut against the tail of the disassembled chain segment on the right, and driving the disassembled chain segment on the right to move to the chain and half-joint assembly station.

[0010] Preferably, the chain and half-mesh connector assembly station is provided with a second chain positioning mechanism, which has the same structure as the first chain positioning mechanism and is used to position the roller chain at the chain and half-mesh connector assembly station.

[0011] Preferably, the half-mesh connector conveying mechanism includes a half-mesh connector vibratory feeder connected to a half-mesh connector guide rail. The vibratory feeder conveys the half-mesh connector to one side of the chain conveyor guide rail via the half-mesh connector guide rail. A third cylinder is fixedly mounted on the upper surface of the machine base on the left side of the half-mesh connector guide rail. The cylinder barrel of the third cylinder is fixedly connected to the machine base. A half-mesh connector feeding block is connected to the piston rod along a direction parallel to the side wall of the chain conveyor guide rail. A half-mesh connector conveying guide rail penetrating the side wall of the chain conveyor guide rail is also provided on one side of the chain conveyor guide rail. A limiting block is provided on the side of the half-mesh connector conveying guide rail away from the half-mesh connector feeding block. One end of the half-mesh connector conveying guide rail is fixedly connected to the limiting block, and the shape and size of its cross-section match the spatial shape and size between the two second connecting parts of the half-mesh connector. A fourth cylinder is provided on the outer side of the half-mesh connector conveying guide rail. The cylinder of the fourth cylinder is fixedly connected to the machine base. The piston rod is connected to the upper and lower opposing joint push plates one and two. The half-eye joint feeding block cooperates with the half-eye joint that is conveyed to one side of the chain conveyor rail and is used to convey the half-eye joint to the half-eye joint conveyor rail. The half-eye joint conveyor rail is inserted between the two second connecting parts and slides with the half-eye joint. The ends of the joint push plates one and two are respectively provided with arc-shaped grooves to limit the left and right displacement of the half-eye joint. The fourth cylinder enters the upper and lower parts of the half-eye joint conveyor rail through the joint push plates one and two respectively and pushes the half-eye joint along the half-eye joint conveyor rail to the inner section of the disassembled chain segment, so that the two second connecting parts of the half-eye joint are respectively in contact with the upper and lower surfaces of the inner section. The connecting holes of the second connecting parts are opposite to the connecting holes of the inner section.

[0012] Preferably, the pin conveying mechanism includes a pin vibratory feeder, a dropping seat, a fifth cylinder, and a pin feeding plate. The pin vibratory feeder is connected to a pin dropping tube via a pin guide rail. The dropping seat includes a first seat plate and a second seat plate that are vertically opposite and fixedly connected. The second seat plate has a guide groove that extends through the front and rear ends. The pin feeding plate is inserted into the guide groove and slidably connected to it. The pin dropping tube passes through the first seat plate. The fifth cylinder is located on the side of the dropping seat away from the chain conveying guide rail. The cylinder barrel of the fifth cylinder is fixedly connected to the machine base, and the piston rod is fixedly connected to the tail of the pin feeding plate. The head of the pin feeding plate is provided with a clamping structure. The clamping structure includes a fixed arm on one side of the head of the pin feeding plate and a movable arm on the other side. The movable arm is hinged to the pin feeding plate via a hinge shaft. The pin feed plate has a clearance groove on one side of its head for the movable arm to pass through. The two ends of the hinge shaft are fixedly connected to the groove wall of the clearance groove. A torsion spring is connected between the hinge shaft and the groove wall of the clearance groove. The rear end of the movable arm has an arc-shaped protrusion that passes through the side opening of the clearance groove. When the fifth cylinder retracts, the side wall of the guide groove squeezes the arc-shaped protrusion. The angle between the movable arm and the fixed arm is such that the pin falling through the pin drop tube falls between the movable arm and the fixed arm. As the fifth cylinder extends, when the arc-shaped protrusion disengages from the groove wall of the guide groove, the movable arm returns to its original position under the action of the torsion spring. The movable arm and the fixed arm press the pin together. At this time, the fifth cylinder delivers the pin to the connecting hole above the second connecting part of the half-mesh connector, which is already in the installation position, through the pin feed plate. After the half-mesh connector is assembled, the pin feed plate retracts to the position of receiving the pin.

[0013] Preferably, the assembly mechanism includes a fixed frame, which includes a cylinder fixing plate disposed above the chain conveyor guide rail. The four corners of the cylinder fixing plate are fixedly connected to the machine base via support columns. A guide plate is fixedly connected below the cylinder fixing plate. A second cylinder is fixedly mounted on the cylinder fixing plate. The cylinder barrel of the second cylinder passes through the cylinder fixing plate and is fixedly connected to it. The piston rod of the second cylinder extends vertically downward and is fixedly connected to a first slider. A first linear guide rail is provided vertically on the inner surface of the guide plate. The first slider is slidably connected to the first linear guide rail. The bottom end of the first slider is connected to a pin pressure nail via a striker seat. The inner surface is connected to a first proximity switch via a bracket. The side wall of the first slider is embedded with a sensing block that cooperates with the first proximity switch. A third cylinder is also provided on the right side of the second cylinder. The cylinder barrel of the third cylinder passes through the cylinder fixing plate and is fixedly connected to the cylinder fixing plate. The piston rod of the third cylinder is connected to a second slider. The inner surface of the guide plate is provided with a second linear guide rail that slides and cooperates with the second slider. The bottom of the second slider is connected to a rivet block via a striker seat. The guide plate is located on one side of the third cylinder and is connected to a second proximity switch via a bracket. The side wall of the second slider is embedded with a sensing block that cooperates with the second proximity switch.

[0014] Preferably, the chain removal station includes a sixth cylinder and a seventh cylinder. The sixth cylinder is fixedly connected to the machine base and is connected to a cylinder mounting base via a cylinder connecting plate. A seventh cylinder is located on the top of the cylinder mounting base. The seventh cylinder is connected to a chain push plate mounting base, and a chain push plate is connected to the top of the chain push plate mounting base. A positioning fork is located at the end of the chain push plate. A material-pulling groove for the positioning fork to slide left and right is opened on the top of the side wall of the chain conveying guide. When the sixth cylinder extends, it moves the cylinder mounting base toward the side of the chain conveying guide, causing the positioning fork to insert into the assembled chain segment. Then, the seventh cylinder extends, driving the positioning fork to move to the right, thus pushing the assembled chain to the right. This action is repeated to push the assembled chain out of the chain conveying guide.

[0015] The advantages of the automated equipment and method for assembling half-mesh joints for roller chains according to the present invention are as follows:

[0016] This invention enables automated assembly of roller chains and half-mesh connectors, replacing manual operation, significantly improving work efficiency and reducing labor intensity. At the same time, this invention also improves the safety factor during the assembly process, reduces safety hazards caused by manual assembly, and ensures the quality of assembled half-mesh connectors and the consistency of assembled chains.

[0036] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0037] The following embodiments can be understood as illustrating a part of the structure or method of the present invention individually, or as combining the embodiments to explain the broader structure or method of the present invention.

[0038] Example 1

[0039] An automated device for assembling half-mesh joints on roller chains, such as Figure 1-17 As shown, the machine includes a machine base 9, a chain conveying guide rail 5-4 arranged on the upper surface of the machine base 9 in the left-right direction, and a disassembly station, a chain and half-mesh connector assembly station 11, a riveting station 13, and a chain removal station 14 arranged sequentially on the upper surface of the machine base where the chain conveying guide rail 5-4 is located; the chain and half-mesh connector assembly station includes a half-mesh connector conveying mechanism 7, a pin conveying mechanism 8, and an assembly mechanism.

[0040] In this embodiment, the disassembly station is used to disassemble the chain. When the disassembled right-side chain segment is moved to the chain and half-mesh connector assembly station, the half-mesh connector is assembled. After the half-mesh connector is assembled, the pin is riveted. Then, the chain is taken out through the chain removal station. The left end of the removed chain is equipped with the half-mesh connector, and it can proceed to the next process. The half-mesh connector conveying mechanism is used to convey the half-mesh connector, the pin conveying mechanism is used to convey the pin, and the assembly mechanism is used to connect the half-mesh connector to the inner single link at the left end of the chain through the pin.

[0041] like Figure 16 The diagram shows the structure of the half-joint 17, which includes two mirror-image "Z"-shaped chain plates. Each "Z"-shaped chain plate has a first connecting part 17-2 that is concave inward and a second connecting part 17-1 that is convex outward. The first connecting parts 17-2 of the two "Z"-shaped chain plates are fixedly connected by a sleeve 17-4. A roller 17-3 is fitted to the outer part of the sleeve 17-4 with a clearance, which essentially forms half of an inner link for connecting with the disassembled outer link of the chain. The second connecting parts 17-1 of the two "Z"-shaped chain plates are fixedly connected by a pin, which essentially forms half of an outer link for connecting with the disassembled inner link of the chain. After connection, the problem of the chain being too loose or too tight can be effectively solved.

[0042] Example 2

[0043] Based on Embodiment 1, this embodiment discloses that: the chain conveyor rail 5-4 is used to convey the roller chain 20, and a drive sprocket 4-1 is rotatably connected to the upper surface of the machine base 9 on one side of the chain conveyor rail 5-4. One end of the drive sprocket 4-1 passes through the side wall of the chain conveyor rail 5-4 and is engaged with the roller chain 20. The axle of the drive sprocket 4-1 passes through the machine base and is fixedly connected to the output shaft of a servo motor (not shown in the figure) preset below the machine base. Under the drive of the servo motor, the roller chain moves to the right along the chain conveyor rail 5-4 to the disassembly station.

[0044] In this embodiment, the chain conveyor guide is a common structure, its function being to convey and guide the roller chain, and a servo motor allows it to precisely reach the desired position. For example... Figure 1 As shown, a controller 3 for controlling the servo motor and other electronic control components of the present invention is fixedly connected to the upper end of the machine base 9.

[0045] Example 3

[0046] Based on Example 1, this example discloses: Figure 1-7 As shown, the disassembly station includes a disassembly device 1 located on one side of the chain conveyor guide rail. The disassembly device 1 includes a hydraulic cylinder 1 fixedly mounted on the machine base via a support frame. The piston rod of the hydraulic cylinder 1 extends downward and is fixedly connected to two disassembly pins arranged side by side at its end. The disassembly pins are used to disassemble the roller chain at the position to be disassembled into two sections. The two disassembled pins and the lower outer chain plate are discharged outward along the pre-set discharge holes 5-10 on the machine base 9. The other disassembled upper outer chain plate is blown... The air mechanism blows air out of the chain conveyor guide rail 5-4. The air mechanism includes an air blowing pipe (not shown in the figure) opposite to the upper outer chain plate. One end of the air blowing pipe is connected to a high-pressure gas supply device. The side wall of the chain conveyor guide rail 5-4 away from the air blowing pipe is provided with a groove 5-9. Under the blowing of the air blowing pipe, the upper outer chain plate is discharged along the groove 5-9. The inner single link at the end of the disassembled chain segment away from the drive sprocket 4-1 forms the installation part for the half-mesh connector 17 to be connected.

[0047] Example 4

[0048] Based on Embodiment 3, this embodiment discloses: Figure 1-7 As shown, the upper surface of the machine base 9 opposite the disassembly device is also provided with a chain positioning mechanism 5. The chain positioning mechanism 5 includes: a positioning fork 5-3 and a first cylinder 5-1 connected to the positioning fork 5-3. The cylinder barrel of the first cylinder is fixedly connected to the upper surface of the machine base, and the piston rod end is connected to the positioning fork. The positioning fork 5-3 matches the shape of the side of the inner single link of the roller chain and is used to insert into the side of the inner single link to press the roller chain 20. The side wall of the chain conveying guide rail 5-4 is provided with a through hole for the positioning fork 5-3 to pass through. A second cylinder 5-5 is provided on one side of the chain positioning mechanism 5-5 and directly opposite the disassembly device 1. The cylinder barrel of the second cylinder 5-5 is fixedly connected to the upper surface of the machine base 9. The piston rod of the second cylinder 5-5 is connected to a first push plate 5-7 and a second push plate 5-8 that are opposite each other through a joint. Figure 6As shown, the head of the first push plate 5-7 forms part of the side wall of the chain conveyor guide 5-4 and is limited by the second cylinder 5-5 to the chain link to be disassembled. The head of the second push plate 5-8 extends towards the disassembly device 1 and forms part of the bottom plate of the chain conveyor guide 5-4. The chain conveyor guide 5-4 has a U-shaped cross-section. The side of the chain conveyor guide 5-4 facing the second cylinder 5-5 has a through hole 2 for the first push plate 5-7 and the second push plate 5-8 to pass through. The side wall of the chain conveyor guide 5-4 opposite to the first push plate 5-7 has a groove 5-9 for the outer chain plate above to be discharged. The head of the second push plate 5-8 has a through hole 3 for the pin shaft to pass through (e.g., Figure 6 As shown in the figure (not marked); In the initial state, the roller chain 20 is positioned at the disassembly station. During disassembly, the pin passes through the discharge hole 5-10 on the through-hole three-way machine 9 and is discharged. The piston rod of the first cylinder rises, the second cylinder retracts, and the first push plate 5-7 and the second push plate 5-8 retract simultaneously. When the second push plate retracts, the discharge hole 5-10 is exposed, and the lower outer chain plate is discharged from the discharge hole 5-10. The upper outer chain plate is blown out of the groove by the air pipe. Afterward, the second cylinder 5-5 extends, and the first push plate 5-7 and the second push plate 5-8 reset. Driven by the drive sprocket 4-1, the roller chain removed on the left continues to move to the right, so that its head abuts against the tail of the chain segment removed on the right, and drives the chain segment removed on the right to move to the chain and half-mesh joint assembly station.

[0049] In this embodiment, when the first and second push plates are assembled with the chain conveyor guide rail, they support the bottom of the chain and slide in cooperation with the side end of the roller chain to guide the movement of the chain conveyor guide rail. When the disassembly is completed, the first and second push plates retract, and the discharge hole opens. The air blowing pipe can be fixed to the top of the first push plate to facilitate blowing the disassembled upper outer chain plate out of the chain conveyor guide rail.

[0050] Example 5

[0051] Based on the above embodiments, this embodiment discloses: Figure 8 As shown, the chain and half-mesh connector assembly station is equipped with a chain positioning mechanism 2 16. The chain positioning mechanism 2 16 has the same structure as the chain positioning mechanism 1 and is used to position the roller chain at the chain and half-mesh connector assembly station to facilitate the assembly of the half-mesh connector.

[0052] Example 6

[0053] Based on the above embodiments, this embodiment discloses: Figure 8 , 9As shown, the half-mesh connector conveying mechanism includes a half-mesh connector vibratory feeder 15-1, which is connected to a half-mesh connector guide rail 15-2. The half-mesh connector vibratory feeder 15-1 conveys the half-mesh connector 17 to one side of the chain conveying guide rail 5-4 via the half-mesh connector guide rail 15-2. A third cylinder 15-3 is fixedly installed on the upper surface of the machine base 9 on the left side of the half-mesh connector guide rail 15-2.

A limiting block 15-12 is provided on the side of the half-mesh connector conveying guide rail 21 away from the half-mesh connector feeding block 15-5. One end of the half-mesh connector conveying guide rail 21 is fixedly connected to the limiting block, and the shape and dimensions of its cross-section match the spatial shape and dimensions between the two second connecting parts of the half-mesh connector. A second half-mesh connector conveying guide rail 21 is provided on its outer side. The cylinder of the fourth cylinder 15-7 is fixedly connected to the machine base 9. The piston rod is connected to the upper and lower opposing joint push plates 15-10 and 15-11. The half-mesh joint feeding block 15-5 cooperates with the half-mesh joint 17 conveyed to one side of the chain conveyor guide rail 5-4 to convey the half-mesh joint 17 to the half-mesh joint conveyor guide rail 21. The half-mesh joint conveyor guide rail is inserted between the two second connecting parts and slides with the half-mesh joint. The joint push plate 15-10 and the joint... The ends of the push plate 15-11 are respectively provided with arc-shaped grooves to limit the left and right displacement of the half-eye connector. The fourth cylinder 15-7 enters the upper and lower parts of the half-eye connector conveying guide rail through the first connector push plate 15-10 and the second connector push plate 15-11 respectively, and pushes the half-eye connector 17 along the half-eye connector conveying guide rail 21 to the inner single section at the end of the disassembled chain segment, so that the two second connecting parts 17-1 of the half-eye connector are respectively attached to the upper and lower surfaces of the inner single section, and the connecting holes of the second connecting parts 17-1 are opposite to the connecting holes of the inner single section.

[0054] Example 7

[0055] Based on the above embodiments, this embodiment discloses: Figure 10-12 As shown, the pin conveying mechanism includes a pin vibratory feeder 10-1, a material dropper, a fifth cylinder 10-3, and a pin feeding plate 10-5. The pin vibratory feeder 10-1 is connected to a pin dropper tube 10-10 via a pin guide rail (tubular, for conveying pins stacked vertically downwards). The material dropper includes a first seat plate 10-8 and a second seat plate 10-7 that are vertically opposite and fixedly connected. The second seat plate 10-7 has a guide groove (e.g., through the front and rear end faces) that passes through the guide groove. Figure 12As shown), the pin feed plate 10-5 is inserted into the guide groove and slidably connected to the guide groove. The pin drop tube 10-10 passes through the first base plate 10-8. The fifth cylinder 10-3 is located on the side of the drop seat away from the chain conveyor guide rail 5-4. The cylinder barrel of the fifth cylinder 10-3 is fixedly connected to the machine base 9. The piston rod is fixedly connected to the tail of the pin feed plate 10-5. The head of the pin feed plate 10-5 is provided with a clamping structure. The clamping structure includes a fixed arm on one side of the head of the pin feed plate 10-5 and a movable arm 10-6 on the other side. The movable arm 10-6 is hinged to the pin feed plate 10-5 through a hinge shaft. Figure 13 As shown, the pin-feed plate 10-5 has a clearance groove 10-12 on one side of its head for the movable arm 10-6 to pass through. Both ends of the hinge shaft are fixedly connected to the groove wall of the clearance groove 10-12. A torsion spring connects the hinge shaft to the groove wall of the clearance groove 10-12. Figure 11-13 As shown, the rear end of the movable arm 10-6 is provided with an arc-shaped protrusion 10-11 that passes through the side opening of the clearance groove. When the fifth cylinder 10-3 retracts, the side wall of the guide groove squeezes the arc-shaped protrusion 10-11. The opening angle between the movable arm 10-6 and the fixed arm satisfies the condition that the pin falling through the pin drop tube 10-10 falls between the movable arm and the fixed arm. As the fifth cylinder extends, when the arc-shaped protrusion 10-11 disengages from the guide groove wall, the movable arm 10-6 returns to its original position under the action of the torsion spring. The movable arm 10-6 and the fixed arm press the pin together. At this time, the fifth cylinder conveys the pin to the top of the connection hole of the second connection part of the half-mesh joint, which is already in the installation position, through the pin feed plate 10-5 (e.g., Figure 12 As shown), after the half-eye connector 17 is assembled, the pin feed plate retracts to the position of receiving the pin.

[0061] Working principle of the invention:

[0062] Before processing, the chain is coiled in the material collection area on machine 9. The roller chain moves via the chain conveyor guide rail and, driven by the drive sprocket, moves to the disassembly station. After being positioned by the first chain positioning mechanism, it is disassembled by the disassembly device. As the servo motor drives the drive sprocket to rotate, the disassembled chain continues to move to the chain and half-mesh connector assembly station, where it is positioned by the second chain positioning mechanism. After half-mesh connector feeding, pin feeding, and pin pressing, the half-mesh connector and the inner single link at the end of the disassembled chain segment are assembled together by the pin. Then, the chain moves to the right to the riveting station to rivet the exposed part of the pin. Finally, the assembled chain is moved to the right by the chain removal station to disengage from the chain conveyor guide rail, ready to enter the next process. This repeated action realizes the automated assembly of the roller chain and half-mesh connector.
