Description

Technical Field

[0001] This utility model relates to the field of automated production line technology in manufacturing, specifically to a fixture return production line. Background Technology

[0002] In modern manufacturing, assembly line operations are one of the key ways to improve production efficiency and reduce costs. Workpieces need to go through multiple processes on the production line, and the efficiency and smoothness of the movement of the fixtures that carry the workpieces between different processes directly affects the capacity of the entire production line.

[0003] Traditional assembly lines typically employ a unidirectional conveyor system, where fixtures move in a fixed direction along the conveyor belt. After a workpiece completes a process, the fixture must be manually returned to its starting position, or a complex robotic arm device must be used to move the fixture for the next cycle of processing. However, these existing traditional assembly line technologies have several drawbacks. On the one hand, manual fixture handling increases labor costs and is physically demanding, failing to meet the growing demands of large-scale production. On the other hand, while complex robotic arm devices alleviate the burden of manual labor to some extent, they are expensive, require complex maintenance, and occupy a large area. Therefore, small and medium-sized manufacturing enterprises need a simple, efficient, and low-cost fixture return assembly line. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a fixture return production line. By setting up a first production line and a second production line that move in parallel and in opposite directions, and combining a steering rod and a guide, the fixture can be automatically returned between the two production lines, reducing manual intervention, lowering equipment costs and maintenance complexity, improving production efficiency, and meeting the needs of small and medium-sized manufacturing enterprises for efficient and low-cost automated production lines.

[0005] Technical Solution: This utility model provides a jig return flow line including a first flow line and a second flow line, which are parallel and side-by-side, with the first and second flow lines moving in opposite directions. A jig is disposed on both the first and second flow lines and moves with them. A steering rod is disposed on the first flow line to guide the jig from the first flow line to the second flow line. By setting up parallel and oppositely moving first and second flow lines, the jig can circulate between the two flow lines, realizing the back-and-forth transport of materials between different processes. The steering rod plays a crucial guiding role, allowing the jig to slide accurately and smoothly from the first flow line to the second flow line, ensuring the continuity of the entire return process.

[0006] Furthermore, in this application, a jig return assembly line is provided. The first assembly line includes a first conveyor belt, and a first baffle is provided on one side of the first conveyor belt. The second assembly line includes a second conveyor belt, which is adjacent to the first conveyor belt and moves in the opposite direction. A second baffle is provided on the side of the second conveyor belt away from the first baffle. The first conveyor belt carries the fixture and drives its movement, providing stable power support for material transportation and ensuring that the fixture can move along the predetermined route, meeting the basic conveying needs of the production line. Similarly, the second conveyor belt provides power for the fixture transported in the opposite direction, ensuring smooth return flow. The first baffle is set along one side of the first conveyor belt, which can effectively prevent the fixture from slipping off the side due to accidental factors such as shaking and collision during the high-speed movement of the conveyor belt, ensuring that the fixture is always on the conveyor belt and maintaining the order of the production line operation. The second baffle plays an equally crucial role in preventing the fixture from slipping off the second conveyor belt, ensuring the safety of reverse transportation. The opposite movement design of the two conveyor belts, combined with the steering rod, enables the fixture to be precisely diverted between the two production lines, allowing the material to flow in an orderly manner in different process links, meeting the fine control of material flow in complex processes.

[0007] Furthermore, in a jig return assembly line of this application, a separator bar is provided adjacent to the first and second conveyor belts. The separator bar is arranged parallel to the first and second baffles and is positioned above the first and second conveyor belts. An inclined plate is installed on the separator bar, and the edge of the inclined plate extends to the first conveyor belt and is slidably connected to it. One end of a steering rod is installed on the first baffle, and the other end is installed on the inclined plate. The steering rod and the separator bar form a first angle. When the jig approaches the turning area, it first contacts the steering rod. Since the steering rod is at a specific angle to the direction of travel of the first conveyor belt, the conveyor belt's own power is cleverly used to gradually guide the jig to change direction and move closer to the separator bar. This natural and smooth guiding method reduces the impact force of the jig turning momentarily and avoids damage to the jig and materials. The inclined plate and the separator bar form a ramp, and the jig can smoothly climb over the separator bar along the ramp under the drive of the first conveyor belt, achieving a smooth transition from the first assembly line to the second assembly line. The steering rod also plays a certain guiding role.

[0008] Furthermore, a fixture return assembly line according to this application also includes a pair of guide members. The guide members are mounted on a partition rod and include a guide rod and a support rod. One end of the guide rod is mounted on the partition rod, and the other end extends to the first transmission belt and the second conveyor belt respectively, making a sliding connection with the first and second conveyor belts. The guide rod and the partition rod form a second angle. One end of the support rod is mounted on the partition rod, and the other end is connected to the guide rod and is perpendicular to the partition rod. The pair of guide members extend to the first and second conveyor belts respectively, guiding the fixture from both sides during fixture transport, further constraining the fixture's position and direction of movement, enabling it to move more accurately along the predetermined route, avoiding lateral deviations, and enhancing the accuracy of the entire assembly line's turning process. A second angle is formed between the guide rod and the partition rod. By appropriately setting this angle, it can be adapted to different fixture sizes, shapes, and production line speeds, thereby better controlling the guiding force and direction of the guide rod on the fixture. This assists the fixture in smoothly completing turning and transition movements. One end of the support rod is mounted on the partition rod, and the other end is perpendicularly connected to the guide rod, providing a stable support structure for the guide rod. This ensures that the guide rod can maintain a stable position and posture even under long-term conditions of fixture friction and vibration generated by production line operation, continuously and effectively playing its guiding role and maintaining the reliability of the entire guiding system.

[0009] Furthermore, in a fixture return line of this application, the first baffle has a defective placement area and a quality inspection area on the side away from the first conveyor belt. Workers observe the fixtures on the production line and manually inspect the fixtures or the workpieces placed on them. The defective placement area provides a dedicated temporary storage space for the detected defective workpieces, and the quality inspection area is used to store workpieces that need to be re-inspected.

[0010] Furthermore, in one jig return assembly line of this application, both the first included angle and the second included angle are adjustable. The adjustability of the first included angle and the second included angle allows the angles between the steering rod and the partition rod, and between the guide rod and the partition rod, to be flexibly changed according to the actual size and shape of the jig.

[0011] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0012] 1. The fixture return assembly line of this utility model, by setting up a first and second assembly line that move in parallel and opposite directions, combined with structures such as steering rods, separators, inclined plates, and guide components, constructs a highly efficient and precise automatic fixture return system. The fixture can circulate between the two assembly lines without manual handling or complex robotic arm operation, greatly reducing labor costs and the labor intensity of workers. Compared with expensive and complex robotic arm handling devices, this assembly line has a simple structure, low equipment cost, small footprint, and significantly reduced maintenance complexity, providing an economical and practical automation solution for small and medium-sized manufacturing enterprises, effectively improving their production efficiency and economic benefits.

[0013] 2. The jig return assembly line described in this utility model ensures the stability and accuracy of jig and material transportation by setting a series of precise guiding and protective structures in key parts. The first and second baffles prevent the jig from slipping and ensure the order of the assembly line operation; the separator rod, inclined plate, and steering rod work together, using a reasonable angle design to cleverly guide the jig to smoothly turn and cross the assembly line. The guide components further constrain the position of the jig from both sides, adapting to various working conditions. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] like Figure 1 , 2 The jig return production line shown has the following structural composition.

[0020] First production line 1: includes a first conveyor belt 11, made of wear-resistant rubber to ensure sufficient friction to drive the fixture to move smoothly. A first baffle 12, made of aluminum alloy, is provided on one side of the first conveyor belt 11.

[0021] The second production line 2 includes a second conveyor belt 21, which has the same specifications as the first conveyor belt 11, is adjacent to the first conveyor belt 11, and moves in the opposite direction. A second baffle 22 is provided on the side of the second conveyor belt 21 away from the first baffle 12. The material and height of the second baffle 22 are the same as those of the first baffle 12, and it serves the same function of preventing edge detachment.

[0022] A separator bar 13 is provided at the adjacent position of the first conveyor belt 11 and the second conveyor belt 21. The separator bar 13 is a square bar, which is set parallel to the first baffle 12 and the second baffle 22 and is slightly higher than the first conveyor belt 11 and the second conveyor belt 21.

[0023] Fixture 3 is a custom-made plastic tray, measuring 30 cm × 20 cm, with anti-slip texture on the bottom that provides moderate friction with the conveyor belt. It is used to carry workpieces and move them on the first production line 1 and the second production line 2.

[0024] One end of the steering rod 4 is mounted on the first baffle 12, and the other end is mounted on the inclined plate 131. The steering rod 4 and the separator 13 form a first included angle α, initially set to 30°. The steering rod 4 is an aluminum alloy rod, which is lightweight and high-strength, and can withstand the impact and friction of the fixture 3.

[0025] The inclined plate 131 is mounted on the separator bar 13, with its edge extending onto the first conveyor belt 11 and slidingly connected to it. The inclined plate 131 is made of 2 mm thick stainless steel plate with a smooth surface, which facilitates the sliding of the fixture 3.

[0026] The guide member 6 includes a guide rod 61 and a support rod 62. One end of the guide rod 61 is mounted on the partition rod 13, and the other end extends to the first conveyor belt 11 and the second conveyor belt 21 respectively, and is slidably connected to the first conveyor belt 11 and the second conveyor belt 21. The guide rod 61 and the partition rod 13 form a second included angle β, initially set to 20°. The guide rod 61 is a square aluminum alloy rod. One end of the support rod 62 is mounted on the partition rod 13, and the other end is connected to the guide rod 61 and is set perpendicular to the partition rod 13. The support rod 62 is also a square aluminum alloy rod, providing stable support for the guide rod 61.

[0027] The defective placement area 8 and the quality inspection area 9 are located on the side of the first baffle 12 away from the first conveyor belt 11. The defective placement area 8 is a workbench used to place the defective workpieces that have been detected. The quality inspection area 9 is also a workbench used to store workpieces that need to be re-inspected.

[0028] Workflow

[0029] initial state

[0030] Fixture 3 is placed at the beginning of the first production line 1 (generated by the previous process), and each fixture 3 holds a workpiece. The first conveyor belt 11 and the second conveyor belt 21 are both in operation. Figure 1 As shown, the first conveyor belt 11 moves to the left, and the second conveyor belt 21 moves to the right.

[0031] Fixture 3 moves on the first production line 1

[0032] As the first conveyor belt 11 moves to the left, the fixture 3 touches the guide rod 61, guiding it to a position near the first baffle 12. It then passes through the defective placement area 8, where workers inspect the fixture. During this movement, the first baffle 12 prevents the fixture 3 from slipping off the side, ensuring that the fixture 3 remains stable on the conveyor belt.

[0033] Fixture 3 turns to the second production line 2

[0034] As the fixture 3 continues to move to the steering rod 4, the fixture 3 gradually changes direction along the steering rod 4 and moves closer to the separator rod 13 under the action of the conveyor belt's power, since the steering rod 4 forms a first angle α of 30° with the direction of travel of the first conveyor belt 11.

[0035] Next, driven by the first conveyor belt 11, the fixture 3 climbs along the inclined plate 131 and crosses the separator bar 13, transitioning from the first production line 1 to the second production line 2.

[0036] Fixture 3 moves and is used in subsequent processing on the second production line 2.

[0037] After fixture 3 enters the second production line 2, it moves to the right along the second conveyor belt 21, completing the cycle.

[0038] As can be seen from the above embodiments, this jig return assembly line can achieve automatic jig return, reducing manual intervention and improving production efficiency. It also features a simple structure, low cost, and convenient maintenance, making it ideal for small and medium-sized manufacturing enterprises. In practical applications, the dimensions, angles, and other parameters of the assembly line can be appropriately adjusted according to different workpieces and production needs to achieve optimal production results.

[0039] The above embodiments are exemplary and are intended to illustrate the technical concept and features of this utility model, so that those skilled in the art can understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
