Description

Technical Field

[0001] This utility model belongs to the field of mechanical automation technology, specifically relating to an auxiliary feeding device for thin steel sheets. Background Technology

[0002] Thin steel sheet feeding refers to the process of continuously and reliably separating and conveying stacked thin steel sheets (typically between 0.3mm and 3.0mm thick) one by one to subsequent processing equipment (such as stamping presses, laser cutting machines, CNC bending machines, and painting lines). It is the first and crucial step in modern metal sheet processing (such as stamping production lines) and is known as the starting point of the "uncoiling line" or "stamping production line".

[0003] Traditional thin steel sheet feeding is mostly done manually, which is not only labor-intensive but also prone to causing workplace injuries due to the sharp steel plates. Furthermore, due to surface flatness and electrostatic adsorption, thin steel sheets tend to stick together when stacked, making individual sheet separation difficult. The surface of thin steel sheets is often coated with anti-rust oil, which affects the adsorption stability of vacuum suction cups, leading to slippage or material falling off. To achieve automated, high-speed, and highly reliable feeding to meet the needs of downstream high-speed processing equipment and replace the traditional, dangerous, and inefficient manual handling and conveying methods, there is an urgent need to design an auxiliary feeding device for thin steel sheets to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary feeding device for thin steel sheets to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary feeding device for thin steel sheets, comprising: A chain conveyor, wherein a crossbar is fixed on the chain of the chain conveyor, and limit bars are fixed at both ends of the frame of the chain conveyor; The storage box is located at the bottom of the chain conveyor. A vibration platform is provided at the bottom of the storage box. An air flotation plate is provided on the inner bottom surface of the storage box. An electric telescopic rod is provided between the bottom two sides of the storage box and the vibration platform. An air pump connected to the air flotation plate is provided on one side of the storage box. The gripping mechanism includes an electric telescopic rod II that is vertically fixed to the bottom of the mounting crossbar. A gripping head is fixed to the bottom end of the electric telescopic rod II. The gripping head is provided with a main gripping unit and an auxiliary gripping unit.

[0006] Furthermore, it also includes a positioning mechanism, which includes a positioning platform disposed on one side of the storage box, fixed plates fixed on the adjacent two sides of the positioning platform, and movable plates on the other two sides. An electric telescopic rod is disposed on one side of the movable plate. The positioning mechanism also includes laser positioners fixed on both sides of the bottom of the gripper head.

[0007] Furthermore, it also includes a testing mechanism, which includes a testing platform set on one side of the positioning platform, and the testing platform is respectively equipped with a thickness testing unit, a flatness testing unit and a surface testing unit.

[0008] Furthermore, it also includes a control mechanism, which is located on one side of the chain conveyor. The control mechanism includes a control cabinet, a touch screen located on the side surface of the control cabinet, and a processor, controller, and communication module located inside the control cabinet.

[0009] Furthermore, a height sensor is provided at the top of the storage box, and a defective product box is provided on one side of the storage box.

[0010] Furthermore, the main gripping unit is located at the center of the bottom of the gripping head and uses an electro-permanent magnet chuck, while the auxiliary gripping units are located at the four corners of the bottom of the gripping head and use pneumatic chucks.

[0011] Furthermore, the vibration platform includes a base frame, rubber springs fixed at the four corners of the top of the base frame, a platform located directly above the base frame and connected to the top of the rubber springs, and a vibration motor fixed to the bottom of the platform.

[0012] Furthermore, the air flotation plate is made of porous ceramic, and the air flotation plate has an equalizing air chamber inside, which is connected to the air outlet of the air pump. A pressure regulating valve and a flow meter are also provided between the air flotation plate and the air pump.

[0013] The technical effects and advantages of this utility model are as follows: The auxiliary feeding equipment for thin steel sheets is advanced in design, compact in structure, easy to use, and reliable in operation. It can effectively solve the problems of high labor intensity, easy to cause work-related injuries, and thin steel sheet adhesion and unstable adsorption that exist in traditional thin steel sheet feeding methods. The chain conveyor ensures continuous equipment operation and stably transports the gripped thin steel sheets to subsequent processing positions. The vibrating platform at the bottom of the storage box, in conjunction with the air flotation plate, effectively separates the adhered thin steel sheets. The electric telescopic rod allows the storage box to tilt at an angle. After the material pile inside the storage box tilts, under the influence of gravity, the loosened steel sheets tend to slide downwards. The tiny gap at the edge of the top layer of steel sheets now becomes an opening, making it easier for external air or airflow seeping in from the bottom to "drill" into this opening. Due to the increased fluid velocity and decreased pressure (Bernoulli's principle / Venturi effect), this gap is automatically sucked in more air and rapidly expands, allowing the gripper head to grab the top steel sheet of the material pile. The main gripping unit of the gripping mechanism uses an electro-permanent magnet chuck, and the auxiliary gripping unit uses a pneumatic chuck. The combination of the two ensures the stability of the gripping and can adapt to the gripping of thin steel sheets of different specifications. The positioning mechanism, driven by a laser positioner and an electric telescopic rod, precisely adjusts the position of the thin steel sheet, ensuring the accuracy of subsequent processing. The detection mechanism, with its thickness, flatness, and surface detection units, comprehensively inspects the thin steel sheet, promptly identifying defective products and collecting them in a defective product box. The control mechanism, via a touchscreen, allows operators to easily set equipment parameters and monitor operation. The processor, controller, and communication module ensure automated operation and data transmission. A height sensor monitors the height of the thin steel sheet in the storage box in real time, facilitating timely replenishment. The vibration platform's rubber springs and vibration motor design ensure effective vibration while minimizing impact on the equipment. The air flotation plate, made of porous ceramic, with its internal pressure equalization chamber, pressure regulating valve, and flow meter, precisely controls the air flotation effect, improving the separation efficiency of the thin steel sheet. In summary, this auxiliary feeding equipment for thin steel sheets, through the coordinated operation of its various mechanisms, achieves automated, high-cycle, and highly reliable feeding of thin steel sheets, effectively improving production efficiency and reducing production costs, and possesses promising market application prospects.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] This utility model provides, for example Figure 1-5 The auxiliary feeding device for thin steel sheets shown includes: Chain conveyor 100, with a mounting crossbar 101 fixed on the chain of chain conveyor 100, and limit stops 102 fixed at both ends of the frame of chain conveyor 100; Storage box 200 is located at the bottom of the chain conveyor 100. Vibration platform 201 is provided at the bottom of storage box 200. Air flotation plate 202 is provided on the inner bottom surface of storage box 200. Electric telescopic rod 203 is provided between the bottom two sides of storage box 200 and vibration platform 201. Air pump 204 connected to air flotation plate 202 is provided on one side of storage box 200. The gripping mechanism 300 includes an electric telescopic rod 301 that is vertically fixed to the bottom of the mounting crossbar 101. A gripping head 302 is fixed to the bottom end of the electric telescopic rod 301. The gripping head 302 is provided with a main gripping unit 303 and an auxiliary gripping unit 304.

[0019] For example, see Figures 1-3 and Figure 5 As shown, it also includes a positioning mechanism 400, which includes a positioning platform 401 disposed on one side of the storage box 200. The positioning platform 401 has fixed plates 402 on its adjacent two sides and movable plates 403 on the other two sides. An electric telescopic rod 404 is provided on one side of the movable plate 403. The positioning mechanism 400 also includes laser positioners 405 fixed on both sides of the bottom of the gripper head 302.

[0020] In this technical solution, the laser positioner 405 can emit a laser beam. Based on the information fed back by the laser, the gripper head 302 can be precisely moved to the top of the storage box 200. After the gripper head 302 grips a thin steel plate and places it on the positioning platform 401, the laser positioner 405 starts working and transmits the detected position information to the control mechanism 600. According to the received information, the control mechanism 600 controls the electric telescopic rod 404 to push the movable plate 403 to move, thereby fine-tuning the position of the thin steel plate so that the thin steel plate is accurately placed in the designated position of the positioning platform 401, preparing for subsequent inspection and processing.

[0021] For example, see Figures 1-3 and Figure 5 As shown, it also includes a testing mechanism 500, which includes a testing platform 501 disposed on one side of the positioning platform 401. The testing platform 501 is provided with a thickness testing unit 502, a flatness testing unit 503 and a surface testing unit 504 respectively.

[0022] In this technical solution, the detection mechanism 500 provides an important guarantee for the quality control of the thin steel sheet. The thickness detection unit 502 can use a high-precision sensor to measure the thickness of the thin steel sheet at different positions to determine whether it meets the production requirements. The flatness detection unit 503 uses optical or mechanical principles to detect the flatness of the surface of the thin steel sheet. If there are unevennesses such as protrusions or depressions, they can be detected in time. The surface detection unit 504 can use image recognition technology to perform a comprehensive scan of the surface of the thin steel sheet to detect defects such as scratches, cracks, and rust. Once a quality problem is detected in the thin steel sheet, the control mechanism 600 will control the gripping mechanism 300 to grab the defective product and place it in the defective product box 206 to prevent the defective product from entering the subsequent processing process.

[0023] For example, see Figure 1 As shown, it also includes a control mechanism 600, which is located on one side of the chain conveyor 100. The control mechanism 600 includes a control cabinet 601, a touch screen 602 located on the side surface of the control cabinet 601, and a processor, controller and communication module located inside the control cabinet 601.

[0024] In this technical solution, the control mechanism 600 serves as the core of the entire equipment, undertaking important tasks such as parameter setting, operation monitoring, and data transmission. Operators can conveniently input the equipment's operating parameters, such as the conveying speed of the chain conveyor 100 and the extension stroke of the electric telescopic rod, through the touch screen 602. The processor analyzes and processes the data fed back by various components of the equipment, and the controller precisely controls the actions of each mechanism according to the processor's instructions. The communication module enables data interaction between the equipment and external systems, facilitating remote monitoring and management of the equipment.

[0025] For example, see Figures 2-4 As shown, a height sensor 205 is provided at the top of the storage box 200, and a defective product box 206 is provided on one side of the storage box 200.

[0026] In this technical solution, the height sensor 205 can monitor the height of the thin steel sheet in the storage box 200 in real time. When the height of the thin steel sheet is lower than the set value, the height sensor 205 will transmit a signal to the control mechanism 600. The control mechanism 600 will remind the operator to replenish the thin steel sheet in time to ensure the continuous operation of the equipment.

[0027] For example, see Figures 2-4 As shown, the main gripping unit 303 is located at the center of the bottom of the gripping head 302 and uses an electro-permanent magnet chuck, while the auxiliary gripping unit 304 is located at the four corners of the bottom of the gripping head 302 and uses a pneumatic chuck.

[0028] In this technical solution, the main gripping unit 303 and the auxiliary gripping unit 304 work together to make the gripping process more stable and reliable. The electro-permanent magnet chuck controls the presence or absence of magnetism by controlling the on / off state of the current, providing strong suction when gripping thin steel sheets to ensure that the steel sheets are firmly adsorbed. Meanwhile, the pneumatic suction cups at the four corners can play an auxiliary fixing role when gripping irregularly shaped or sized thin steel sheets, compensating for the potential problems of insufficient suction or unstable adsorption of the electro-permanent magnet chuck. This dual-suction cup design can adapt to thin steel sheets of various specifications and shapes, greatly improving the versatility and reliability of the equipment.

[0029] For example, see Figures 1-3 As shown, the vibration platform 201 includes a base frame, rubber springs fixed at the four corners of the top of the base frame, a platform set directly above the base frame and connected to the top of the rubber springs, and a vibration motor fixed to the bottom of the platform.

[0030] In this technical solution, the base frame of the vibration platform 201 provides a stable support for the entire vibration system. The rubber springs fixed at the four corners of the top of the base frame play a role in buffering and shock absorption. When the vibration motor starts, the platform will vibrate. The rubber springs can effectively absorb the impact force generated by the vibration, reduce the impact on other parts of the equipment, and also reduce the noise generated during the operation of the equipment.

[0031] For example, see Figure 5 As shown, the air flotation plate 202 is made of porous ceramic. The air flotation plate 202 has an equalizing air chamber inside, which is connected to the air outlet of the air pump 204. A pressure regulating valve and a flow meter are also provided between the air flotation plate 202 and the air pump 204.

[0032] In this technical solution, the air flotation plate 202 is made of porous ceramic. Its internal pressure equalization chamber can ensure that the gas delivered by the air pump 204 is evenly distributed on the surface of the air flotation plate 202. The setting of the pressure regulating valve and flow meter can accurately adjust the gas pressure and flow rate according to different conditions of the thin steel sheet, thereby achieving precise control of the air flotation effect and ensuring that the adhered thin steel sheet can be separated efficiently.

[0033] Working Principle: When using this auxiliary feeding device for thin steel sheets, the operator first sets the operating parameters of the equipment through the touch screen 602 of the control mechanism 600, such as the conveying speed of the chain conveyor 100 and the extension stroke of the electric telescopic rod. After the equipment is started, the chain conveyor 100 starts to run, providing continuous power for the entire feeding process. At this time, the height sensor 205 monitors the height of the thin steel sheets in the storage box 200 in real time. If the height of the thin steel sheets is normal, the vibration platform 201 starts to work, the vibration motor starts, driving the table to vibrate. The rubber spring plays a buffering and shock absorption role, reducing the impact on other parts of the equipment. At the same time, the air pump 204 starts to work, and the gas is regulated... After precise adjustment of the pressure valve and flow meter, the air enters the pressure equalization chamber of the air flotation plate 202 and is then evenly sprayed from the surface of the porous ceramic air flotation plate 202, causing the thin steel sheet in the storage box 200 to be in an air-floating state, effectively separating the adhered thin steel sheet. The laser positioner 405 emits a laser beam, and based on the information fed back by the laser, the gripper head 302 is precisely moved to directly above the storage box 200. The electro-permanent magnet chuck of the main gripping unit 303 is energized and generates magnetism, and the pneumatic chuck of the auxiliary gripping unit 304 begins to suck in air. The two work together to firmly grip a thin steel sheet. After the gripper head 302 grips the thin steel sheet, the electric telescopic rod 301 retracts, lifting the thin steel sheet to a certain height, and then the chain... The conveyor 100 moves the gripper head 302 above the positioning platform 401. The gripper head 302 descends and places the thin steel sheet on the positioning platform. The laser positioner 405 operates again, transmitting the detected position information of the thin steel sheet to the control mechanism 600. Based on the received information, the control mechanism 600 controls the electric telescopic rod 404 to push the movable plate 403 to move, fine-tuning the position of the thin steel sheet so that it is accurately positioned at the designated location on the positioning platform. Then, the gripper mechanism 300 grips the thin steel sheet from the positioning platform 401 and places it on the detection platform 501. The detection mechanism 500 begins operation, with the thickness detection unit 502, flatness detection unit 503, and surface... The detection unit 504 detects the thickness, flatness, and surface quality of the thin steel sheet. If a quality problem is detected, the control mechanism 600 controls the gripping mechanism 300 to grab the defective sheet and place it in the defective sheet box 206. If the thin steel sheet is of acceptable quality, the gripping mechanism 300 grabs it and places it on the next workstation, completing one feeding process of the thin steel sheet. Throughout the process, the height sensor 205 continuously monitors the height of the thin steel sheet in the storage box 200. When the height of the thin steel sheet is lower than the set value, the height sensor 205 transmits a signal to the control mechanism 600, which then reminds the operator to replenish the thin steel sheet in time to ensure the continuous and stable operation of the equipment. Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
