Description

Technical Field

[0001] The present invention relates to the technical field of clamping of copper clad laminates, and particularly to a copper clad laminate clamping system and a clamping and flipping method. Background Art

[0002] A copper clad laminate generally refers to a copper clad laminate, which is a plate-like material made by impregnating an electronic glass fiber cloth or other reinforcing material with resin, and covering one or both sides with a copper foil and then hot pressing. It is simply called a copper clad laminate. Various printed circuit boards with different forms and functions are processed, etched, drilled, and copper plated selectively on the copper clad laminate to make different printed circuits. It mainly plays the roles of interconnection conduction, insulation, and support for the printed circuit board, and has a great influence on the signal transmission speed, energy loss, and characteristic impedance in the circuit. Therefore, the performance, quality, processability, manufacturing level, manufacturing cost, and long-term reliability and stability of the printed circuit board largely depend on the copper clad laminate.

[0003] In the prior art, when the copper clad laminate is flipped after being clamped, the flipping angle of the copper clad laminate cannot be effectively measured before and after flipping, and then the position of the copper clad laminate cannot be judged and controlled and adjusted, resulting in inaccurate flipping during the flipping process of the copper clad laminate, which affects the processing effect of the copper clad laminate. Therefore, the present invention proposes a copper clad laminate clamping system and a clamping and flipping method. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a copper clad laminate clamping system and a clamping and flipping method. The present invention obtains the clamping information during the clamping process of the copper clad laminate, extracts and analyzes the clamping parameters, obtains the distance change during the flipping process of the copper clad laminate, calculates the angle flipping value of the copper clad laminate, and measures the angle during the flipping process of the copper clad laminate. By comparing the measured angle with the calculated angle, the accuracy of flipping is further improved.

[0005] To achieve the above object, the present invention is realized by the following technical solutions: A copper clad laminate clamping system includes a copper plate information acquisition module, a data analysis module, an angle monitoring module, a rotation control module, a server, and a data calculation module; the copper plate information acquisition module, the data analysis module, the angle monitoring module, the rotation control module, and the data calculation module are respectively connected to the server for data connection;

[0006] The copper plate information acquisition module obtains the clamping information during the clamping process of the copper clad laminate, and extracts the clamping parameters in the clamping information; the clamping parameters are sent to the data calculation module to obtain its flipping angle reference value;

[0007] The server transmits the flipping angle reference value to the data analysis module; the angle monitoring module detects the angle change of the marked points on the copper clad laminate, transmits the flipping angle to the server, and the server records the flipping angle.

[0008] The data analysis module receives the flipping angle reference value and the flipping angle recorded in the server, analyzes the flipping position of the copper clad laminate, and transmits the analysis result to the rotation control module. The rotation control module adjusts the flipping angle of the copper clad laminate based on the analysis result.

[0009] Further, when rotating during the clamping process of the copper clad laminate, marking points are set on the clamping piece. The positions of the marking points are on the same plane as the horizontal clamping surface of the copper clad laminate. When the copper clad laminate is horizontally clamped, a measurement point is set at one end of the clamping piece to measure the distance of the copper clad laminate and obtain the initial measurement distance value; obtain the intermediate measurement distance value after the copper clad laminate rotates 90°; obtain the maximum measurement distance value after the copper clad laminate rotates 180°. Set the initial measurement distance value as CLJLzmin; the intermediate measurement distance value: CLJLzzj; the maximum measurement distance value is: CLJLzmax.

[0010] The clamping information includes the marked distance value, the initial measurement distance value, and the distance change value. Analyze the change interval of the distance change value. Set the distance change value as: JLBHz; the marked distance value as: BJJLz; define the marked distance value and the initial measurement distance value as clamping parameters and transmit the clamping parameters to the data calculation module.

[0011] Further, the data calculation module receives the marked distance value and the initial measurement distance value to obtain the flipping angle reference value. Set the flipping angle reference value as: FZJDCKz; connect the two endpoints of the marked distance value and the initial measurement distance value to form a triangle. Thus, the included angle between the marked distance value and the initial measurement distance value is the flipping angle reference value, and the flipping angle reference value is transmitted to the data analysis module.

[0012] Further, when the data analysis module performs data analysis, it is as follows:

[0013] When the angle of the copper clad laminate changes, obtain the distance change value. Arrange the obtained multiple distance change values in the order of acquisition, and select the maximum distance change value. Set the maximum distance change value as: JLBHzmax; if JLBHzmax < CLJLzzj, the angle reference value obtained during data calculation is the flipping angle reference value. If CLJLzzj > JLBHzmax < CLJLzmax, the angle change value obtained during data calculation is the actual angle reference value, and add 90° to the obtained value to get the flipping angle reference value.

[0014] If the calculated JLBHzmax = CLJLzmax, observe whether JLBHzmax is the last one during the arrangement. If it is the last one, the obtained angle change value is 180°. If it is in the middle position, obtain the value that is the same as CLJLzzj. If there is only one group that is the same as CLJLzzj, add 180° to the obtained value to get the reference value of the flipping angle. If there are two groups that are the same as CLJLzzj, add 225° to the obtained value to get the reference value of the flipping angle.

[0015] Further, the angle monitoring module obtains the change value of each flip of the copper clad laminate and transmits the obtained flipping angle to the server. The server calculates the reference value of the flipping angle and compares whether the obtained flipping angle is the same as the reference value of the flipping angle. If they are the same, it means that the measurement of the flipping angle is accurate. If they are different, the maintenance personnel re-measure the flipping angle and calibrate the angle monitoring module or the data calculation module.

[0017] Step S1: Obtain the clamping information during the clamping process of the copper clad laminate and extract the clamping parameters from the clamping information;

[0018] Step S2: Transmit the clamping parameters to the data calculation module to obtain its reference value of the flipping angle;

[0020] Step S3: Monitor the angle change of the marked point position on the copper clad laminate through the angle monitoring module, transmit the flipping angle to the server, and the server records the flipping angle;

[0021] Step S4: The data analysis module receives the reference value of the flipping angle and the flipping angle recorded in the server, analyzes the flipping position of the copper clad laminate, and transmits the analysis result to the rotation control module. The rotation control module adjusts the flipping angle of the copper clad laminate based on the analysis result.

[0022] Further, in the step S1, when clamping the copper plate, the specific steps are as follows:

[0023] Step S11: Set a marked point on the copper clad laminate clamping piece, and the position of the marked point is on the same plane as the horizontal clamping surface of the copper clad laminate;

[0024] Step S12: When the copper clad laminate is horizontally clamped, set a measurement point at one end of the clamping piece, measure the distance of the copper clad laminate, and obtain the initial measurement distance value;

[0025] Step S13: Obtain the intermediate measurement distance value after the copper clad laminate is rotated by 90°; obtain the maximum measurement distance value after the copper clad laminate is rotated by 180°, and set the initial measurement distance value as CLJLzmin; the intermediate measurement distance value: CLJLzzj; the maximum measurement distance value is: CLJLzmax;

[0026] Step S14: Analyze the change interval of the distance change value, set the distance change value as: JLBHz; the marked distance value is: BJJLz; define the marked distance value and the initial measurement distance value as the clamping parameters.

[0027] Further, in step S2, when obtaining the flipping angle reference value, it is specifically as follows:

[0028] Receive the marked distance value and the initial measurement distance value to obtain the flipping angle reference value; connect the two endpoints of the marked distance value and the initial measurement distance value to form a triangle, and the included angle between the marked distance value and the initial measurement distance value is the flipping angle reference value.

[0029] Further, in step S2, when the data analysis module analyzes the flipping angle reference value, the specific steps are as follows:

[0030] Step S21: When the angle of the copper clad laminate changes, obtain the distance change value, arrange the obtained multiple distance change values in the order of acquisition, select the maximum distance change value, and set the maximum distance change value as: JLBHzmax;

[0031] Step S22: If JLBHzmax < CLJLzzj, then the angle reference value obtained during data calculation is the flipping angle reference value;

[0032] Step S23: If CLJLzzj > JLBHzmax < CLJLzmax, then the angle change value obtained during data calculation is the actual angle reference value, and add 90° to the obtained value to get the flipping angle reference value;

[0033] Step S24: If the obtained JLBHzmax = CLJLzmax, observe whether JLBHzmax is the last one during arrangement. If it is the last one, then the angle change value is 180°. If it is in the middle position, obtain the value that is the same as CLJLzzj among them. If there is only one group that is the same as CLJLzzj, then add 180° to the obtained value to get the flipping angle reference value. If there are two groups that are the same as CLJLzzj, then add 225° to the obtained value to get the flipping angle reference value.

[0042] The copper clad laminate information acquisition module obtains the clamping information during the clamping process of the copper clad laminate and extracts the clamping parameters in the clamping information;

[0043] When rotating during the clamping process of the copper clad laminate, marking points are set on the clamping piece, and the position of the marking points is in the same plane as the horizontal clamping surface of the copper clad laminate. When the copper clad laminate is horizontally clamped, a measurement point is set at one end of the clamping piece to measure the distance of the copper clad laminate and obtain the initial measurement distance value; obtain the intermediate measurement distance value after the copper clad laminate rotates 90°; obtain the maximum measurement distance value after the copper clad laminate rotates 180°. Set the initial measurement distance value as CLJLzmin; the intermediate measurement distance value: CLJLzzj; the maximum measurement distance value is: CLJLzmax;

[0044] The clamping information includes a marked distance value, an initial measured distance value, and a distance change value. Analyze the change range of the distance change value, and set the distance change value as: JLBHz; the marked distance value as: BJJLz; define the marked distance value and the initial measured distance value as clamping parameters;

[0045] Send the clamping parameters to the data calculation module to obtain its reference value of the flipping angle;

[0046] The data calculation module receives the marked distance value and the initial measured distance value to calculate the reference value of the flipping angle. Set the reference value of the flipping angle as: FZJDCKz; connect the two endpoints of the marked distance value and the initial measured distance value to form a triangle. Thus, the included angle between the marked distance value and the initial measured distance value is the reference value of the flipping angle.

[0047] ; Thus, obtain the reference value of the flipping angle;

[0048] Send the reference value of the flipping angle to the data analysis module;

[0049] When the data analysis module conducts data analysis, it is as follows:

[0050] When the angle of the copper clad laminate changes, obtain the distance change value. Arrange the obtained multiple distance change values in the order of acquisition, and select the maximum distance change value. Set the maximum distance change value as: JLBHzmax; if JLBHzmax < CLJLzzj, the angle reference value obtained during data calculation is the reference value of the flipping angle. If CLJLzzj > JLBHzmax < CLJLzmax, the angle change value obtained during data calculation is the actual angle reference value. Add 90° to the obtained value to get the reference value of the flipping angle. If the calculated JLBHzmax = CLJLzmax, observe whether JLBHzmax is the last one during the arrangement. If it is the last one, the angle change value is 180°. If it is in the middle position, obtain the value that is the same as CLJLzzj. If there is only one group that is the same as CLJLzzj, add 180° to the obtained value to get the reference value of the flipping angle.

[0052] The angle monitoring module obtains the change value of each flip of the copper clad laminate, and conveys the obtained flip angle to the server. The server calculates the reference value of the flip angle, and compares whether the obtained flip angle is the same as the reference value of the flip angle. If they are the same, it means that the measurement of the flip angle is accurate. If they are different, the maintenance personnel re-measure the flip angle and calibrate the angle monitoring module or the data calculation module.

[0053] The data analysis module receives the reference value of the flip angle and the flip angle recorded in the server, analyzes the flip position of the copper clad laminate, and conveys the analysis result to the rotation control module.
