Description

Technical Field

[0001] The present utility model relates to the technical field of automated material feeding and receiving for assembly lines, and specifically relates to an automatic material feeding and receiving device for docking assembly line products. Background Art

[0002] Since its emergence in the early 20th century, the assembly line production mode has become the core method for large-scale production in the manufacturing industry. The material feeding and receiving link serves as the "head and tail hub" of the assembly line, and its automation level directly affects production efficiency and cost control. In the early stage, the material feeding and receiving of assembly lines completely relied on manual operations, where workers needed to manually carry materials to the assembly line stations or retrieve finished products from the stations. This mode was widely applied in the early development stage of the manufacturing industry due to the low equipment threshold. However, with the rise of labor costs and the acceleration of production rhythm, its defects such as severe labor waste, low operation efficiency, and high labor intensity have become increasingly prominent, and it can no longer meet the demands of large-scale production.

[0003] To solve the drawbacks of manual material feeding and receiving, mechanized material feeding and receiving solutions have been gradually introduced in the industry, among which the most representative one is the combined system of "manipulator + special feeder". Such systems realize the grabbing and transferring of materials through the manipulator, and cooperate with the special feeder to complete the sorting and conveying of materials, which greatly reduces manual intervention and improves operation efficiency. However, this combined system has obvious shortcomings: first, the equipment cost is high, the purchase prices of the manipulator and the special feeder are much higher than those of ordinary automation components, and a complex control system is required as a supporting facility; second, the energy consumption is high, the multi-axis driving of the manipulator and the continuous operation of the feeder consume a large amount of electric energy and compressed air; third, the maintenance difficulty is high, the system involves multiple complex components such as manipulator joints and precision sensors, which requires professional and technical personnel to carry out daily operation and maintenance, and the replacement cost is high after the components are damaged; fourth, the failure rate is high, the complex mechanical structure and control logic make the system susceptible to environmental interference (such as dust and vibration), thereby affecting production continuity. To sum up, the existing assembly line material feeding and receiving technology is caught in the dilemma of "low efficiency of the manual mode and high cost of the mechanical combination", and there is an urgent need for an automation solution that takes into account low cost, high reliability and convenient maintenance to overcome the core defects of the prior art.

[0005] To achieve the aforementioned goals of low cost, low failure rate, convenient maintenance, and high degree of automation, this utility model provides the following technical solution: an automatic feeding and receiving device for docking production line products, comprising a main frame, on which a material preparation area and a material distribution area are sequentially arranged along the material transmission direction, and a chain conveying mechanism driven by a motor is connected between the material preparation area and the material distribution area; a top material electric cylinder that moves vertically is installed in the material distribution area, and a horizontally telescopic material distribution cylinder is arranged beside the top material electric cylinder, and the telescopic stroke of the material distribution cylinder covers the material channel of the material distribution area.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1 and Figure 2As shown, an automatic material feeding and receiving device for a production line includes a main frame 1. A material preparation area 11 and a material distribution area 12 are sequentially arranged on the main frame 1 along the material conveying direction. A chain conveyor mechanism 2 driven by a motor connects the material preparation area 11 and the material distribution area 12. A vertically lifting electric cylinder 3 is installed in the material distribution area 12. A horizontally extending material distribution cylinder 4 is arranged beside the lifting electric cylinder 3, and the extension stroke of the material distribution cylinder 4 covers the material channel of the material distribution area 12. Through the coordinated work of the motor-driven chain conveyor mechanism 2, the lifting electric cylinder 3, and the material distribution cylinder 4, automatic material conveying, lifting, and distribution are achieved, significantly reducing manual intervention and improving production efficiency. The material preparation area 11 and the material distribution area 12 are sequentially arranged along the material conveying direction, and the chain conveyor mechanism 2 connects... Both components contribute to a compact overall structure, effectively saving space on the production floor. The top-loading electric cylinder 3 rises and falls vertically, accurately lifting the materials stacked in the preparation area 11 one by one to the distribution position. The distribution cylinder 4 extends and retracts horizontally, precisely pushing the lifted materials to the designated position, achieving efficient and accurate material distribution. Driven by a motor, the chain conveyor mechanism 2 transports the materials from the preparation area 11 to the distribution area 12, preparing for subsequent material distribution operations without the need for manual handling, greatly reducing the labor intensity of workers. The top-loading electric cylinder 3 lifts the stacked materials one by one to the distribution position, and the distribution cylinder 4 pushes the lifted materials to the designated position, achieving accurate material distribution and ensuring that each material can be accurately conveyed to the next process, improving product quality and production efficiency.

[0020] like Figure 2As shown, the chain transmission mechanism 2 includes a first driving sprocket 21, a first driven sprocket 22, and a first transmission chain 23. The first driving sprocket 21 is keyed to the output shaft of the motor. The first driven sprocket 22 is rotatably mounted on the main frame 1 via a bearing seat 24. The first transmission chain 23 is meshed and sleeved on the outside of the first driving sprocket 21 and the first driven sprocket 22. The meshing transmission method of the sprocket and chain has high transmission efficiency, ensuring that the power output by the motor is effectively transmitted to the transmission chain, reducing energy loss and improving overall transmission efficiency. The transmission mechanism consists of only a few components such as sprockets, chains, and bearing seats 24, with a simple and clear structure, making daily maintenance and troubleshooting relatively easy, reducing maintenance costs and time. The meshing transmission between the sprocket and the chain is relatively smooth, reducing impact and vibration during transmission, thereby lowering noise levels, improving the production environment, and enhancing work comfort. The chain conveyor mechanism 2, as a key component of the equipment, is responsible for continuously and stably conveying materials from the preparation area 11 to the distribution area 12 or other designated locations without manual intervention, achieving automated material transfer and improving production efficiency. The chain conveyor mechanism 2 works in conjunction with components such as the top-loading electric cylinder 3 and the distribution cylinder 4 to complete the material feeding and receiving operations. During feeding, the chain conveyor mechanism 2 conveys the material to the distribution area 12; during receiving, it conveys the divided material to the receiving platform or other subsequent processes.

[0021] like Figure 2 and Figure 3As shown, a material support plate 13 is detachably connected to the top of the top material cylinder 3. The top surface of the material support plate 13 is parallel to the conveying surface of the chain conveying mechanism 2, and the length of the material support plate 13 is not less than the width of the material channel of the material distribution area 12. The material support plate 13 and the top material cylinder 3 are detachably connected, which facilitates the quick replacement of different specifications of material support plates 13 according to the size, shape, or material distribution requirements of the material. The top surface of the material support plate 13 is parallel to the conveying surface of the chain conveying mechanism 2, ensuring that the material remains horizontal when it is conveyed from the chain to the material support plate 13, avoiding material slippage, jamming, or positioning deviation due to tilting, which can significantly reduce the damage rate during the transmission process. The length of the material support plate 13 is not less than the width of the material channel of the material distribution area 12, which can fully support the material conveyed by the chain, and prevent the material from being partially suspended or falling due to the material support plate 13 being too short. As the connecting component between the chain conveyor mechanism 2 and the material distribution area 12, the parallel top surface design ensures that the material maintains a horizontal posture during transmission, avoiding tilting or overturning of the material due to height differences or angle deviations, and providing stable support for the precise pushing of the subsequent material distribution cylinder 4. During the material distribution process, the top material cylinder 3 lifts the material support plate 13 along with the material to a designated height. The material support plate 13 covers the material distribution channel with its length, evenly distributing the weight of the material and preventing heavy materials from falling or deforming due to excessive local force, thus ensuring the accuracy of the material distribution action. The top surface of the material support plate 13 is parallel to the material channel of the material distribution area 12, providing a horizontal reference surface for the material distribution cylinder 4. When pushing the material, the material distribution cylinder 4 can use the edge of the material support plate 13 as a positioning reference to achieve precise sorting of the material in the material distribution area 12 and improve the material distribution efficiency.

[0022] like Figure 2As shown, a material distribution block 41 is fixedly connected to the end of the piston rod of the material distribution cylinder 4. The height of the material distribution block 41 is greater than the thickness of a single piece of material and less than the total thickness of two stacks of material. The height of the material distribution block 41 is greater than the thickness of a single piece of material, ensuring that when the top material cylinder 3 lifts the material, the block can reliably block the top layer of material, preventing it from sliding back to the preparation area 11 due to inertia or vibration, thus achieving accurate separation of a single layer of material. The height of the block is less than the thickness of two stacks of material, avoiding the block from simultaneously jamming two layers of material when the material stack in the preparation area 11 is not neat, which could lead to material distribution failure or equipment jamming. When the top material cylinder 3 lifts the stacked material to the material distribution position, the material distribution cylinder 4 drives the block to extend and insert into the gap between the top layer of material and the bottom layer of material. Because the height of the baffle is greater than the thickness of a single layer, the lower layer of material is blocked in the preparation area 11, while the upper layer of material is pushed to the distribution channel by the baffle, completing the single-layer separation. If the height of the baffle is greater than or equal to the thickness of two layers of material, when the material in the preparation area 11 is not stacked neatly, the baffle may jam two layers of material at the same time, causing the distribution cylinder 4 to overload or the material to jam. This solution limits the height of the baffle to ensure that it can only separate a single layer of material, thus avoiding such failures. The distribution baffle 41 works in conjunction with the top material cylinder 3. After the top material cylinder 3 lifts the material to the height where the baffle can be inserted, the distribution cylinder 4 is activated, and the baffle separates the single layer of material. Then the top material cylinder 3 descends, and the remaining material in the preparation area 11 falls back to its original position, waiting for the next top material, thus achieving continuous and stable single-layer feeding.

[0023] like Figure 2 and Figure 4 As shown, height-adjustable support feet 5 are installed at the four bottom corners of the main frame 1. The support feet 5 are connected to the main frame 1 by threads. The height of the support feet 5 can be adjusted by rotating the threads, which can quickly compensate for uneven ground and ensure that the equipment is stably grounded at all four corners, avoiding tilting or vibration of the equipment due to one side being suspended.

[0024] like Figure 4 As shown, a second driving sprocket 7, a second driven sprocket 71, and a second conveying chain 72 are installed on one side of the material distribution area 12. The second driving sprocket 7 is keyed to the output shaft of the material distribution cylinder 4. The second conveying chain 72 is meshed and sleeved on the outside of the second driving sprocket 7 and the second driven sprocket 71. When the output shaft of the material distribution cylinder 4 rotates, it drives the second driving sprocket 7 to rotate, and drives the second driven sprocket 71 to rotate through the chain meshing. At the same time, the chain moves in a straight line, converting the rotational motion of the cylinder into the linear reciprocating motion of the material distribution block 41, thereby realizing the separation or pushing of materials.

[0025] like Figure 1As shown, the material distribution area 12 is connected to the conveyor belt 6 of the production line. The material distribution area 12 is directly connected to the conveyor belt 6 of the production line. The material that has been distributed can immediately enter the conveyor belt without manual handling or intermediate storage, thus eliminating the material stagnation time. The conveyor belt runs at a constant speed, synchronized with the periodic action of the material distribution cylinder 4, to realize the continuous flow operation of "material distribution-conveying" and improve the overall work efficiency.

[0026] like Figure 3 As shown, the material distribution area 12 is also equipped with a material tray limit frame 14; the material tray limit frame 14 uses a three-sided side limit structure to forcibly limit the movement range of the material tray in the X / Y direction, ensuring that the material distribution mechanism can accurately align with the center of the material tray or the designated position; each time material is distributed, the material tray is fixed in the same position by the limit frame, eliminating the material distribution error caused by the placement deviation of the material tray and improving the production yield.

[0027] Working principle: 1. Material feeding process: The stacked materials are manually placed on the first conveyor chain 23 of the preparation area 11. After the equipment is started, the chain conveyor mechanism 2 conveys the materials to the distribution area 12. The top material cylinder 3 rises, and the material support plate 13 lifts the materials off the first conveyor chain 23. Then, the distribution cylinder 4 extends, the distribution block 41 inserts between the stacked material layers, the top material cylinder 3 descends to the initial position, and the lower layer of single material falls onto the conveyor chain. The distribution area 12 then connects to the feed end of the production line to complete the feeding. The top material cylinder 3 rises again to lift the remaining materials, the distribution cylinder 4 retracts, and the above steps are repeated until all the materials in the preparation area 11 are fed.

[0028] 2. Material Receiving Process: Finished materials from the production line are conveyed to the sorting area 12 via the production line conveyor belt 6; the sorting cylinder 4 extends, the sorting block 41 holds the material, and the top material electric cylinder 3 rises to lift the material away from the first conveyor chain 23; when the material receiving quantity reaches the set value, the sorting cylinder 4 retracts, the top material electric cylinder 3 descends, and the material falls onto the first conveyor chain 23, which is then conveyed to the preparation area 11 by the chain conveyor mechanism 2. The finished materials are then manually removed from the preparation area 11, completing one material receiving cycle.

[0029] In summary, this automated feeding and receiving equipment for the production line, with its minimalist combination of "main frame 1 + chain conveyor mechanism 2 + cylinder dispensing mechanism," replaces the complex structure of the traditional "robotic arm + dedicated feeder." The core components are all standard, conventional parts, with procurement costs only 1 / 3 to 1 / 2 of traditional systems. Furthermore, it eliminates the need for complex customized development, significantly lowering the investment threshold. Simultaneously, the standardized components are highly versatile and can be quickly replaced in case of failure, solving the problems of traditional systems requiring specialized personnel for maintenance and difficulty in procuring spare parts. Ordinary on-site maintenance personnel can complete routine maintenance.
