It forms the mechanism. The lubrication lever (3) lubrication cap (4) 25 The subject is the mechanism of motion. Oil tank and supply pump. (11), feeding of the lubricant to be applied to the lubrication head (4) It provides. X-axis motion system (1) is driven by the X-axis drive motor (6); Y-axis The motion system (2) is driven by the Y-axis drive motor (5). 30 The control unit (8) controls the movement and lubrication of the said drive motors. The camera unit (7) monitors the lubrication application of the head (4). transmits the image to the control unit (8); the infrared temperature sensor (9) transmits the mold image to the control unit (8); 6 It provides the measurement data regarding the temperature to the control unit (8). Workbench / chassis (10) forms the structure that carries the mechanical and other components of the system. In the system's operation, after the mold to be lubricated is placed in the press, X The axis movement system (1) and the Y-axis movement system (2) have a central reference. is brought to position. The camera unit (7) captures at least one image of the mold placed in the press. It obtains. In one application, mold recognition and lubrication reference points. A single image is used for identification. The acquired image is displayed in the control unit. (8) is processed by the image processing algorithm found. The control unit (8) displays the mold surface contours, gaps and It automatically classifies the mold type by analyzing its boundaries. There are 10 types that can be classified. Mold types include Z-rod, rod end, control arm, ball joint, and ball joint arm molds. Determining the mold type involves identifying the lubrication reference points and records for that mold. This is related to selecting the relevant recipe, if applicable. Thus, it belongs to different mold types. lubrication data are stored separately in the memory of the control unit (8). It can be held. 15 The control unit (8) selects one or more of the mold surfaces from the received image. The operator determines the coordinates of the lubrication reference point and the mold-specific movement path. It determines this automatically without needing prior instruction. In the application, six lubrication reference points are determined for the mold surface. The number of reference points is not limited to this application example and can be 20 on the mold surface. This can vary depending on the geometry and the areas to be lubricated. Pixel positions of lubrication reference points determined from the image, Machine coordinates are determined using previously performed camera-axis calibration. It is transformed. As a result of this transformation, the points determined on the image are linked to X. 25 to be accessed by the axis movement system (1) and the Y-axis movement system (2) A coordinate relationship is established between physical locations. Here, pattern-specific pre-teaching takes place. Camera-axis calibration and camera-axis calibration are different processes. calibration involves converting image coordinates to machine coordinates. This is a pre-calibration related to the lubrication path for each mold. It does not require training from the operator. 30 Lubrication reference points converted to machine coordinates, X-axis The movement to be followed by the motion system (1) and the Y-axis motion system (2) 7 It creates the path. The control unit (8) records the movement associated with the classified mold type. and controls the lubrication cycle using lubrication parameters. Each The amount of oil to be applied and / or the lubrication time at the coordinate point will be determined according to the relevant mold. The lubrication parameters belonging to the control unit (8) are used by the mold press. Each time it is installed, the lubrication reference points are recalculated based on the image taken. 5 Since the machine coordinates of the points in question were determined, the actual coordinates of the pattern at that moment It is reconstructed according to its position and size. The recorded movement belonging to the relevant mold type. And the lubrication parameters can be reused in subsequent production cycles. During the movement phase of the lubrication cycle, the X-axis movement system (1) and Y The axis movement system (2) is first returned to the starting (Home) position. Control 10 unit (8) is determined from the image in the relevant production cycle and machine coordinates are assigned to it. The first of the converted lubrication reference points is set as the target position on the X-axis. Lubrication head (4), provides lubrication to the drive system (1) and the Y-axis drive system (2). The lubrication lever (3) is moved to the target position and the lubrication reference They are positioned sequentially along the points. 15 Control unit (8), X-axis movement system (1) and Y-axis movement the speed of movement of the system during its approach to the target coordinate point (2) It lowers automatically. In this movement pattern, the axes are between the coordinates. While moving at a higher speed at the beginning of the movement, towards the target coordinate It moves at a lower speed during the approach. Thus, the distance between the coordinates is 20 Movement time and positioning accuracy at the lubrication point together It is monitored. The speed reduction operation is controlled by the control unit (8) to the servo axes. This is accomplished through movement commands. The lubrication cap (4) is placed at each designated lubrication reference point. Lubrication amount and / or lubrication time determined according to the coordinates 25 The lubrication agent applies. The amount of oil and / or lubrication time is determined according to the lubrication requirements of the relevant mold. It is controlled by the control unit (8) using the parameters. Control unit (8) movement of the lubrication head (4) and lubrication application to the relevant mold. It monitors the machine coordinates and lubrication parameters in relation to lubrication. Article 30 from the oil tank and supply pump (11) to the lubrication head (4) It is fed and applied to the mold surface via the lubrication nozzle (4). 8 The system is designed to monitor the lubrication process depending on the mold temperature. It includes an infrared temperature sensor (9). The infrared temperature sensor (9) is molded It measures the temperature without directly contacting the mold surface. Lubrication cycle During this time, the mold temperature is mentioned before the Y-axis movement system (2) retracts. The subject is measured via the sensor and the obtained temperature data is sent to the control unit (8) 5 is transmitted. The control unit (8) transmits the measured temperature to the predetermined operating temperature. It compares it within the range. The measured mold temperature is outside the specified operating range. In case of a fault, the control unit (8) generates an alarm and stops the lubrication process. It activates the mechanism. Thus, the lubrication application is carried out under temperature conditions of 10 If it is not suitable, it is cut off by the control unit (8) and the operator is warned. In practice, the operating temperature range is defined as 80–250 °C. The temperature range in question is an example value related to the application, and the system has different patterns. and does not limit its use in lubrication conditions. After the lubrication process is completed, the control unit (8), X axis 15 motion system (1) and Y-axis motion system (2) start automatically It returns to the (Home) position. In the next production cycle, the recorded recipe for the relevant mold is used. Lubrication reference points and their associated movements are recalled from memory. The application parameters are reusable. The study is shown in Figure 2. In the workflow, mold image acquisition, image processing and control operations, servo 20 Movement of the axes, lubrication application, lubrication via oil tank and pump. the feeding of the material and the feedback received from the infrared temperature sensor The relationship between them is shown. One application of the invention involves image processing for different types of tattoo dies. The mold type is determined via this method, and the lubrication reference points for the mold surface are 25. The mold boundaries are created each time the mold is placed in the press, based on the image taken. and lubrication reference points are redefined and determined according to the actual position of the mold at that moment and It is recalculated according to the measurement. The pixel positions of the points in question, The machine is used with conversion data related to camera-axis calibration. It is converted to coordinates. Lubrication head (4), X-axis movement system (1) and Y 30 along the coordinates of the machine in question by the movement of the axis of the motion system (2) as it moves; its movement speed is reduced as it approaches the target machine coordinates, and each Lubrication reference point: the amount of oil and / or lubrication time for the relevant mold. 9 is applied. Mold temperature, Y-axis movement system (2) before retraction The measured temperature is measured by the infrared temperature sensor (9); the measured temperature is determined for the working If the temperature is outside the range, the control unit (8) generates an alarm and It stops the lubrication process. In one application, the control unit (8) takes the pattern 5 by the camera unit (7). By processing the image, the outer boundaries, voids, and geometric lines of the mold surface are determined. It determines the relevant regions in the image, such as grayscale transformation, thresholding, and edge. The resulting contours are separated by determination processes; area, perimeter and number of voids. geometric features such as those of mold types recorded in the memory of the control unit (8) The mold type is classified by comparing it with geometric definitions. The control unit (8) is the same 10 The contours define the outer boundaries of the mold surface and the area enclosed by these boundaries; From these boundaries, the boundary box is obtained, which is the smallest rectangle surrounding the mold. Lubrication reference points are determined based on the edge lengths of this boundary box. It is created by placing it in proportioned positions. In an application, the boundary box Three proportional positions are determined along its width and two along its height, and these are 15 Six lubrication reference points are obtained from their intersections. The positions of the points are determined. Since it is calculated proportionally to the size of the mold, different sizes and geometries In molds, the points are distributed by scale on the mold surface automatically, and the mold This ensures even lubrication across the entire surface. In the arrangement, the location of the lubrication points is determined by the operator on the machine 20 As was not taught, the pattern-specific offset or position values were not entered into the system beforehand. No introduction is needed; the points are simply boundaries and areas determined from the image. It is calculated using the boundaries shown in the image each time the mold is placed in the press. Since they were redefined, the lubrication reference points are now based on the actual position of the mold. and recalculated according to its size. 25 The pixel coordinates of each reference point obtained from the image, with camera-axis calibration done beforehand to machine coordinates It is transformed. For example, the mold surface on the calibrated plane. In an application where pixel coordinates (u, v) and machine coordinates (X, Y) are present. The relationship between them can be defined by the relations X = a₁u + a₂v + a₃ and Y = b₁u + b₂v + b₃. 30 Here, the coefficients a₁, a₂, a₃, b₁, b₂, and b₃ represent the distances between the camera and the X and Y axes. These are conversion coefficients determined as a result of prior calibration. The subject is affine transformation, as well as the scale difference between the camera and the axis system. Because it also accommodates rotational and tilting effects, the mold is within the image plane. Even when positioned at different angles, the reference points remain the same on the machine. are converted into coordinates. The control unit (8) uses these coefficients Reference points extracted from the image X-axis motion system (1) and Y-axis Converts to machine coordinates to be accessed by the movement system (2). 5 Control unit (8), sequential lubrication reference points of the lubrication head (4) its movement between them, the machine coordinates for each reference point target By giving the X-axis motion system (1) and the Y-axis motion system (2) in position This is accomplished by the servo drives of these motion systems. The defined maximum speed of movement and acceleration and deceleration acceleration values are 10. within this framework, a positioning velocity profile that will remain on the target coordinate. It applies this profile in the form of a trapezoid in one application and an S-curve in another. This is possible. In this way, the axes can move at a specified speed between two reference points. and as it approaches the target coordinate, its movement speed is automatically reduced. Lubrication head (4) without overshooting the target point and without vibration 15 It is stopped. The control unit (8) stores the movement speed and acceleration in the recipe for each mold type. It uses the values of the lubrication head (4) in different mold geometries; thus, the lubrication head (4) The transition time between points is determined in accordance with the relevant mold, and lubrication is applied. The process is completed within the cycle time. 25
