Description

Technical Field

[0001] The present invention relates to the technical field of semi-automatic assembly lines, in particular to a semi-automatic assembly line. Background Art

[0002] Traditional chain assembly relies heavily on manual labor, which is not only inefficient but also difficult to ensure precision and consistency. Especially in large-scale production scenarios, traditional manual assembly methods are particularly clumsy and unable to meet the efficiency and precision requirements of modern industrial production.

[0003] To overcome this challenge, researchers have begun to incorporate automation technology into the chain assembly process. However, due to the unique characteristics of chains, the assembly process requires a high degree of precision and coordination, making the design of automated assembly lines extremely complex. Currently, most automated chain assembly lines on the market suffer from complex structures and high maintenance costs, making them difficult to achieve ideal results in practical applications. Summary of the Invention

[0004] In order to overcome the above-mentioned defects in the prior art, a semi-automatic assembly line is provided.

[0006] Preferably, the hydraulic system includes a machine body and a hydraulic press head; the hydraulic press head is mounted on the machine body and can be raised and lowered along the height of the machine body. The hydraulic press head is mounted on the machine body to form a compact overall structure, reducing floor space, making the assembly line layout more rational, and also facilitating equipment maintenance and upkeep.

[0007] Preferably, the hydraulic press head includes a connecting head, a hydraulic press cylinder, and a clamp structure; the connecting head is used to connect the hydraulic press head and the machine body, the clamp structure is assembled at the bottom of the connecting head, and the hydraulic press cylinder is assembled on both sides of the clamp structure to drive the clamp structure to clamp the chain parts. The connecting head serves as a bridge between the hydraulic press head and the machine body, ensuring that the hydraulic press head can be stably assembled on the machine body and allowing the hydraulic press head to move up and down along the height direction of the machine body, so that the hydraulic press head can accurately clamp the chain parts and maintain a stable clamping force during the assembly process.

[0008] Preferably, the cylinder feeding device includes a base and a feeder cylinder, a push rod assembly and a storage frame assembled on the base; a push rod assembly connected to the feeder cylinder is installed under the storage frame, and several chain parts are placed in the storage frame; the cylinder feeding device can automatically push the chain parts out of the storage frame for subsequent assembly, thereby improving assembly efficiency.

[0009] Preferably, the push rod assembly includes a groove and a push rod. The groove is used to support a chain component, and one end of the push rod is connected to the groove and the other end is connected to the feeder cylinder. The groove ensures that the component is firmly supported and prevents it from slipping or being damaged during the pushing process. The push rod ensures that it can withstand the required force and pressure during the pushing process and maintains a stable motion trajectory.

[0010] Preferably, a feeder cylinder drives a push rod assembly to transfer the chain components from the storage frame to the fixture structure. This makes the entire feeding process highly automated and precise, significantly improving production efficiency and quality. Furthermore, the use of the feeder cylinder as the driving force, coupled with the precise coordination of the push rod assembly and the fixture structure, ensures the stability and reliability of the chain components during transfer.

[0011] Preferably, the main body is located on one side of the semi-automatic assembly area, while the base matches the main body's position and is located on the other side. The relative positioning of the base and main body ensures smooth, unobstructed transfer of chain components from the storage frame to the fixture structure. This rational layout makes assembly more efficient.

[0012] Preferably, the top surface of the base is lower than the bottom of the fixture structure. This ensures that chain parts can smoothly transition from one position to another during transport. This design helps reduce bumps and collisions during transport, thereby improving transport stability and accuracy.

[0013] Preferably, the conveyor belt device is equipped with a plurality of retaining structures for securing the chain components, and the retaining structures are evenly spaced along the conveyor belt device. The retaining structures are used to secure the chain components, preventing them from shifting or tumbling during conveyance, thereby ensuring that the components are conveyed to their destination along the predetermined path and at the predetermined speed.

[0014] Preferably, multiple chain hoppers are provided, one located in the manual unloading area of ​​the conveyor belt device and one on the side of the robot. The chain hopper located in the manual unloading area of ​​the conveyor belt device is mainly used for manual placement of chain parts; the chain hopper located on the side of the robot is mainly used for automated feeding, improving the flexibility and efficiency of the production line.

[0015] Compared with the prior art, the present invention has the following beneficial effects: A semi-automated assembly line uses a conveyor belt device to continuously and stably transport chain parts, significantly reducing the time required for manual handling. The precise grasping and placement functions of the robot and the automated feeding capabilities of the cylinder feeding device greatly shorten the assembly cycle and improve the efficiency of the overall assembly line.

[0016] Furthermore, a semi-automated assembly line enhances assembly accuracy. The precise grabbing and placement functions of the robot ensure that chain parts can be quickly and accurately placed in the predetermined position. The coordinated work of the hydraulic system and the cylinder feeding device realizes the automatic pressing of chain parts, reducing assembly errors caused by human factors.

[0017] Furthermore, a semi-automatic assembly line has a reasonable layout. The hydraulic system includes a machine body and a hydraulic press head. The hydraulic press head can be raised and lowered along the height direction of the machine body, making the assembly line layout more compact and reasonable and reducing the floor space. The base and the machine body are in a relative position, ensuring that the chain parts can be smoothly transferred from the storage frame to the fixture structure. The layout is reasonable and the assembly efficiency is improved.

[0018] Furthermore, the hydraulic press head's connecting head ensures a stable assembly to the machine body and allows for lifting and lowering motion, thus maintaining a stable clamping force during assembly. The groove and push rod design of the push rod assembly ensures the stability and reliability of the chain parts during transport, reducing bumps and collisions during transport.

[0019] Furthermore, to improve the flexibility of the production line, multiple chain hoppers are provided, which are respectively arranged in the manual discharge area of ​​the conveyor device and on one side of the robot. This design enables the production line to flexibly respond to changes in different production needs. Other features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0022] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0023] like Figures 1 to 5As shown, a semi-automatic assembly line is used to assemble chain parts 6, including a conveyor belt device 1, a manipulator 2, a hydraulic system 3, a cylinder feeding device 4 and a chain hopper 5; the conveyor belt device 1 is divided into a manual discharge area 11, an automatic assembly area 12 and a semi-automatic assembly area 13, the manual discharge area 11 is the manual discharge area at the front end of the conveyor belt device 1, and the operator places the lower half of the chain parts 6 on the manual discharge area 11; in the automatic assembly area 12, the manipulator 2 places the middle part of the chain parts 6 from the chain hopper 5 on the lower half of the chain parts 6 for combination; in the semi-automatic assembly area 13, the hydraulic system 3 and the cylinder feeding device 4 are used to press the lower half of the chain parts 6 and the middle part of the chain parts 6 assembled previously with the upper half of the chain parts 6 to form a complete assembly.

[0024] The conveyor belt device 1 is used to transport chain parts 6 from various locations. It can continuously and stably transport chain parts 6, reducing manual handling time and improving part movement efficiency. A manipulator 2 is located in the automatic assembly area 12 of the conveyor belt device 1 and is used to precisely grasp and place chain parts 6. This precise grasping and placement function allows the manipulator 2 to quickly and accurately place chain parts 6 in the desired location, significantly shortening the assembly cycle. The hydraulic system 3 and the cylinder feeder 4 are located in the semi-automatic assembly area 13 of the conveyor belt device 1. The hydraulic system 3 and the cylinder feeder 4 work together, allowing the cylinder feeder 4 to convey the chain parts 6 to the hydraulic system 3. The hydraulic system 3 is used to press the chain parts 6 together, achieving automated pressing of the chain parts 6 and further improving the efficiency of the overall assembly line. The automated and semi-automated assembly processes reduce reliance on manual labor and reduce the company's labor costs. The introduction of automated assembly lines reduces workers' exposure to dangerous, repetitive, or heavy work and improves their working environment.

[0025] Chain hoppers 5 are located next to the conveyor belt device 1 and are used to place chain parts 6. There are multiple chain hoppers 5, located in the manual discharge area 11 of the conveyor belt device 1 and on one side of the robot 2. The chain hoppers 5 located in the manual discharge area 11 are mainly used for manually placing chain parts, allowing operators to quickly and conveniently add parts to the conveyor belt when needed, thereby ensuring the continuous operation of the production line. The chain hoppers 5 located on the side of the robot 2 are mainly used for automated feeding. The robot 2 can grab chain parts 6 from these chain hoppers 5 and place them in the appropriate position on the conveyor belt, which increases the automation level of the production line, reduces manual intervention, and thus improves production efficiency and accuracy.

[0026] Hydraulic system 3 comprises a body 31 and a hydraulic press head 32. Hydraulic press head 32 is mounted on body 31 and can be raised and lowered along the height of body 31, ensuring a more stable and efficient pressing process for chain components 6. This design, combined with hydraulic press head 32 on body 31, forms a compact overall structure. This reduces floor space, streamlines assembly line layout, and facilitates equipment maintenance.

[0027] The hydraulic press head 32 includes a connecting head 321, a hydraulic cylinder 322, and a clamp structure 323. The connecting head 321 serves as a bridge between the hydraulic press head 32 and the machine body 31, ensuring that the hydraulic press head 32 can be stably assembled on the machine body 31 and allowing the hydraulic press head 32 to move up and down along the height direction of the machine body 31. The clamp structure 323 is assembled at the bottom of the connecting head 321, and the hydraulic cylinder 322 is assembled on both sides of the clamp structure 323 to drive the clamp structure 323 to clamp the chain component 6. The clamp structure 323 can firmly clamp the component and prevent it from moving or being damaged during the assembly process. The hydraulic cylinder 322 provides stable driving force for the clamp structure 323.

[0028] The cylinder feeding device 4 includes a base 41 and a feeder cylinder 42, a push rod assembly 43 and a storage frame 44 assembled on the base 41; the base 41 is the supporting structure of the entire cylinder feeding device 4, providing sufficient stability and load-bearing capacity to ensure that the device can operate smoothly; the feeder cylinder 42 is the power source for driving the push rod assembly 43 to move, and a push rod assembly 43 connected to the feeder cylinder 42 is installed under the storage frame 44, and several chain parts 6 are placed in the storage frame 44.

[0029] The feeder cylinder 42 pushes the push rod assembly 43 to transfer the chain parts 6 in the storage frame 44 to the clamp structure 323; the specific steps are: when feeding is required, the feeder cylinder 42 receives pressure from the hydraulic or pneumatic system and starts to generate thrust, which is transmitted to the chain parts 6 in the storage frame 44 through the push rod assembly 43, causing the chain parts 6 to move along the opening direction of the storage frame 44. As the push rod assembly 43 continues to move, the chain parts 6 are pushed out of the storage frame 44 one by one and sent to the subsequent clamp structure 323 for pressing; once all the chain parts 6 are pushed out, the feeder cylinder 42 stops working and waits for the next feeding instruction.

[0030] The push rod assembly 43 includes a groove 431 and a push rod 432. Groove 431 is the portion of the push rod assembly 43 that supports the chain element 6. The size of groove 431 matches the shape and size of the chain element 6 to ensure that it can be securely supported and prevent it from slipping or being damaged during the pushing process. Groove 431 is used to support a chain element 6. One end of the push rod 432 is connected to groove 431, and the other end is connected to the feeder cylinder 42. The push rod assembly 43 and the feeder cylinder 42 work together to enable the push rod assembly 43 to accurately support the chain element 6 and push it out of the storage frame 44 for subsequent assembly.

[0031] The machine body 31 is located on one side of the semi-automatic assembly area 13, while the base 41 is positioned to match the machine body 31 and is located on the other side of the semi-automatic assembly area 13. This rational layout allows for faster transfer and assembly of chain components, thereby improving production efficiency. Chain components 6 are transferred from the storage frame 44 on the base 41 to the fixture structure 323 on the machine body 31 for subsequent assembly operations, making the process from storage to assembly of chain components 6 more streamlined.

[0032] The top surface height of the base 41 is lower than the bottom height of the clamp structure 323. This ensures that the chain part 6 can smoothly transition from one position to another during the transmission process, helps reduce the bumps and collisions of the chain part 6 during the transmission process, and thus improves the stability and accuracy of the transmission.

[0033] The conveyor belt device 1 is provided with several limiting structures 14 for fixing the chain parts 6 to prevent the chain parts 6 from moving or rolling during the transmission process, reduce collision and friction between parts, and thus reduce the damage rate of parts; several limiting structures 14 are evenly arranged on the conveyor belt device 1. The evenly arranged limiting structures 14 can ensure that each part has enough space on the conveyor belt to avoid excessive crowding or overlapping between them; making the spacing between the chain parts 6 consistent can make it easier to achieve automated processing.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
