Description

Technical Field

[0001] The utility model relates to the technical field of precision grinding, in particular to a loading and unloading device for a full-automatic circular table surface grinder. Background Art

[0002] Metal circular saw blades are discs with a large diameter-to-thickness ratio. To ensure performance and improve appearance, both sides must be ground with a high level of precision. Currently, the most commonly used equipment for grinding circular saw blades is a circular table surface grinder, which clamps the saw blade (workpiece) onto an electromagnetic chuck, which drives the saw blade in rotation. The grinding head uses the end face or circumference of a large-diameter disc grinding wheel for grinding. As the grinding head moves up and down and left and right, it can grind the entire side of the saw blade. However, the loading and unloading process of existing surface grinders is generally manual. Some workpieces are heavy, which can easily lead to loading and unloading difficulties and low efficiency. The workpiece surface is also easily scratched, reducing production efficiency. Utility Model Content

[0005] Technical Solution

[0006] In order to solve the above problems, the technical solution provided by the present invention is as follows:

[0007] A loading and unloading device for a fully automatic circular table surface grinder includes a truss, a movable seat and a slide rail, wherein the movable seat is provided with a lifting column; a manipulator is connected to the lower end of the lifting column, and the manipulator is provided with a magnetic coil; a workstation assembly line includes a blank station, a finished product station, an inspection station, a cleaning station, a flipping station and a grinding station arranged in sequence in a straight line, and each station is arranged corresponding to the slide rail. The manipulator can be moved to any station, and the flipping station includes a connected rotating shaft and a flipping suction cup, and the flipping suction cup corresponds to the grinding station after flipping.

[0008] The truss serves as the supporting structure for the entire system, ensuring stable operation of other components. The mobile base moves along rails, providing the robot with the necessary freedom of movement, enabling it to reach different workstations and perform its tasks. Lifting columns mounted on the mobile base allow the robot to move up and down to accommodate varying heights. The robot is equipped with magnetic coils that can attract workpieces, such as metal circular saw blades, for easy handling. The robot's design allows for flexible movement between different workstations, performing both loading and unloading tasks. The workstation assembly line includes multiple stations, including rough workstations, finished product stations, inspection stations, cleaning stations, flipping stations, and grinding stations, each responsible for a specific processing step. The flipping station, in particular, utilizes a rotating axis and flipping suction cups to flip workpieces to the desired angle for further processing or inspection. This system features a high degree of automation, reducing manual labor, improving production efficiency, and offering excellent stability. The robot's precise control and the strategic layout of the workstations ensure consistent and high-quality workpiece handling. The optimized clamping and handling methods reduce the risk of surface scratches and damage to the workpiece.

[0009] Optionally, the manipulator also includes a suction cup frame, a buffer column and a sensor. The suction cup frame is provided with two plates arranged upper and lower, the buffer column is elastically arranged between the two plates, the sensor is fixed to the upper plate, and the lower plate is provided with an empty slot for passing the sensor probe.

[0010] The suction cup holder design consists of two plates arranged one above the other. This design not only increases the stability of the robot when grasping the workpiece, but also provides installation space for other components such as buffer columns and sensors. The buffer column is elastically arranged between the two plates, which can absorb the impact force when the robot grasps or places the workpiece, preventing damage or position shifting of the workpiece due to sudden collisions. This helps to protect the workpiece and the robot itself while improving the accuracy of the operation. The sensor is fixed to the upper plate, and the lower plate is provided with an empty slot for the sensor probe to pass through. This means that the sensor can directly monitor the status or position of the workpiece, such as detecting whether the workpiece is correctly adsorbed or released, to ensure that each operation is accurate. In addition, the sensor can also be used to detect environmental changes such as temperature and humidity, further improving the intelligence level of the system.

[0011] Optionally, a contact block is provided on the lower surface of the lower plate.

[0012] The contact block helps the robot achieve more precise positioning when placing a workpiece. When the robot places the workpiece at the target location, the contact block first contacts the workpiece or workstation surface. Sensor feedback ensures that the workpiece's placement and orientation meet the requirements. The contact block acts as a buffer during placement, reducing the possibility of the robot directly impacting the workpiece or workstation surface, thereby preventing damage or displacement.

[0013] Optionally, a center positioning rod is provided at the center of the blank workstation and the finished product workstation, and supporting blocks are provided around the center positioning rod.

[0014] The centering rod provides a stable support point, preventing the workpiece from shifting or tilting during handling or machining. Support blocks positioned around the centering rod evenly support the workpiece, ensuring balanced force in all directions. This helps prevent workpiece deformation or damage. The support blocks can be adjusted or replaced to accommodate workpiece sizes and shapes, allowing the system to accommodate a wide variety of workpiece types and enhancing the versatility and flexibility of the equipment.

[0015] Optionally, the cleaning station is arranged above the cleaning box, and a connected water tank is provided on the top of the cleaning box. The detection station and the cleaning station are both arranged at the position of the water tank, and the detection station includes a bracket with a sensor.

[0016] A cleaning tank is located below the cleaning station to store cleaning fluid, ensuring that workpieces are fully exposed to the cleaning fluid during the cleaning process, removing surface dirt and impurities. Both the inspection and cleaning stations are located near the sink. This layout allows workpieces to enter the cleaning station directly after inspection, reducing intermediate transfer steps and improving production efficiency. The inspection station includes a bracket with a sensor. The bracket is designed to allow workpieces to be inspected at different heights to accommodate different types of inspection equipment and methods. The adjustable bracket also helps adjust the position of the workpiece to ensure the accuracy of the inspection results.

[0017] Optionally, a lifting block, a lifting slide rail and a lifting screw are provided inside the movable seat. The lifting block is slidably matched with the lifting slide rail, and a thread is provided inside the lifting block.

[0018] The lifting block is a component installed inside the moving base, responsible for connecting the robot and the lifting system. The lifting block is equipped with a threaded hole inside, which cooperates with the lifting screw to achieve precise vertical movement. The lifting rail is a guide rail fixed inside the moving base, which is used to guide the up and down movement of the lifting block. The lifting rail ensures the stability and linearity of the lifting block in the vertical direction, avoiding shaking and deviation during movement. The lifting screw is a rotating shaft with a thread that is driven to rotate by a motor. When the lifting screw rotates, the lifting block that cooperates with it will move in the vertical direction under the guidance of the lifting rail. The design of the lifting screw can achieve precise displacement control, ensuring that the robot is accurately positioned between workstations at different heights.

[0019] Optionally, a grinding movable platform is provided at the bottom of the grinding station, and the grinding movable platform is slidably matched with a grinding slide rail, and the end of the grinding slide rail is matched with the position of the grinding mechanism.

[0020] The grinding table is a platform installed at the bottom of the grinding station, used to carry the workpiece and move it horizontally. The design of the grinding table allows the workpiece to be precisely positioned during the grinding process, ensuring the accuracy and consistency of the grinding operation. The grinding slide is a guide rail fixed to the bottom of the grinding station, used to guide the horizontal movement of the grinding table. The grinding slide ensures the stability and linearity of the grinding table in the horizontal direction, avoiding shaking and deviation during movement. The grinding mechanism is a grinding tool installed above or on the side of the grinding station, used to grind the workpiece. The end of the grinding slide matches the position of the grinding mechanism to ensure that the workpiece on the grinding table can be accurately moved into the working range of the grinding mechanism.

[0021] Optionally, a partition is provided on the periphery of the grinding station.

[0022] The partition can effectively isolate the grinding area, prevent the debris, dust and splashes generated during the grinding process from flying out, and protect the safety of operators and other equipment.
