Description

Method for automatically cutting printed circuit board

The present invention relates to an automatic cutting method of a printed circuit board (PCB), and more particularly to an automatic cutting method of a printed circuit board that can simultaneously cut a substrate having a plurality of the same pattern in a desired shape.

In general, a printed circuit board (PCB) is cut and processed by printed circuit board CAD data on a front substrate made of copper foil, and uniformly mixed with an epoxy resin, a curing agent, a catalyst, and a solvent. After making the vanish and impregnating the glass fiber mat, it is dried at a constant temperature to increase the adhesiveness to proceed a part of the curing reaction, and then cut and aligned to a certain size, followed by pressing under appropriate heating and pressure with the copper thin film. . Finally, cut to the desired panel size and inspect the appearance thickness and weight.

The printed circuit board (PCB) is made through a series of machining and chemical processes and then pattern design using a commercially available substrate design CAD (for example, P-CAD, OR-CAD, CADSTAR, PADS, etc.) After the surface mounting (S / M) process on the patterned substrate is made into a mold, a circuit pattern in which the electronic component is mounted is provided.

In this case, the molded printed circuit board (PCB) has the same circuit pattern on the substrate, and these circuit boards are precisely cut into squares and rectangles to be commercialized by cutting them into one independent printed circuit board (PCB). Will cut.

The molded printed circuit board (PCB) cutting machine is currently being used in place of a silicon wafer cutting machine. The fixed printed circuit board (PCB) mounted on the rotating means is fixed to the cutting means, and one cutting means is applied to the cutting portion. It moves to front and rear ends by about 2mm and cuts one side or one line. In this case, in order to instruct the cutting process to the cutting machine, a program must be written in the form of a complex NC code, and there are many limitations in partial operation, which is inconvenient for the user. In addition, additional costs and time are required when new cutters are installed or when the process is changed, and investment for user training is required.

Therefore, the existing mold printed circuit board (PCB) cutting machine has to program in the form of inconvenient code, which is difficult to write to cut the circuit board, resulting in time and money loss, and additionally the initial installation cost and the process change cost. There is a disadvantage that occurs. In addition, these cutters are not suitable for small quantity production of a large number of varieties, and when it is difficult to prepare a code for operating the cutter from the user's point of view, there is a problem that errors are likely to occur, and actions and corrections are difficult when errors occur.

The present invention has been made to solve the above problems of the prior art, the object of the present invention is easy to use, easy to change the various parameters, the user by creating a cutter operating program that supports more functions than the existing parameters If you input the NC code automatically to operate the cutting machine to operate the cutter efficiently and economically to provide a printed circuit board automatic cutting method to improve the work performance at the same time.

Fig. 16A is a flowchart showing the position and speed display of the automatic cutting method of the printed circuit board. The display of the position and speed is automatically executed in the dialog frame at the bottom left of the main menu, automatically created when the dialog frame is executed, and automatically destroyed when the program is terminated. It is possible and cannot be destroyed or hidden. The update of position and velocity in the dialog frame calls a timer function containing a position velocity update code by setting a timer to 0.1 seconds when the dialog frame is generated (step S1). Position and velocity updates are read out from the register of the motion controller 20 board (step S2) and converted into units of mm taking into account the pitch and motor pulses (step S3) and displayed in the list box (step S4).

16B is a flowchart showing an I / O display of an automatic cutting method of a printed circuit board. The display of I / O and home status is done by a dialog frame in the middle of the bottom of the main menu. Like the position and speed display, it is automatically created when the program is executed and automatically destroyed when it is finished. During the use of the program, the user can move only the position and cannot destroy or hide it. The I / O and home limit update calls the timer function containing the I / O and home limit update code by setting the timer to 0.1 seconds when the dialog frame is generated (step S7). The I / O and limit update reads data from the register of the motion controller board 20 (step S8), finds the specified I / O and home limit data, analyzes the position (step S9), and displays it in a list box ( Step S10).

16C is a flowchart illustrating an external input / output display of an automatic cutting method of a printed circuit board. The external I / O display can be executed separately from other menus and used to check for equipment set-up or failure, and the update of I / O is called by a timer function (step S11) in the register on the motion controller board 20. If the data is read (step S12) and the I / O number is less than 24, the position of each I / O data is analyzed (step S14), and each I / O data is displayed in a list box (step S15). Check if the number is less than 24, and if it is more than 24, end.

16D is a flowchart showing an X, Y, Z, θ axis setting display of an automatic cutting method of a printed circuit board. The X, Y, Z, θ axis setting display reads the data necessary for the ini file by reducing the input error by showing the setting values for the axis (step S18) and checks whether it is the end of the data (step S17). If it is the end of data, the process is terminated. If it is not the end of data, the data is converted (step S19), and the setting, motor setting, home setting, jog setting, limit setting, and limit switch of each axis are displayed in a list box. (Step S20).

On the other hand, the display of the dicing parameters is loaded with the data required in the ini file for the operation information, the initial position, return point, index, cutting distance, cutting depth, multi-stage index, multi-stage cutting, feed speed for each mode on the display screen , Cutting speed, etc. are displayed.

The access algorithm of the motion controller 20 board is composed of a digital input detection algorithm, a digital output detection algorithm, a transfer algorithm, and a homing algorithm. In the digital input detection algorithm, since the external input terminal signal determined through the digital input setting comes in a 24-bit signal, the operation for signal detection is performed on the position of the predetermined terminal number in order to detect the signal set in the 24-bit number. Since the off signal is detected, the number of terminals is detected by masking a binary number and by masking a 24-bit signal. The mask is generated by bit movement of the terminal number. The digital output algorithm, like a digital input, sends out a signal to an output terminal determined by an external output setting. The digital output algorithm makes a 24-bit number, adds a mask to it, and sends the output to the outside. Since the transfer algorithm should wait for the next sensor until the transfer is completed when the table is transferred, it is important to check at the end of the transfer rather than the transfer itself. Perform position control with.

16E is a flowchart illustrating a homing algorithm of an automatic cutting method of a printed circuit board. The homing algorithm is an operation of finding the origin of the home sensor, but may be viewed as a part of the conveyance. However, the homing algorithm is composed of a conveying operation and an operation of finding the origin after passing through the home sensor. The homing operation proceeds with a homing command (step S27), so that the next operation must not be performed until the end of homing, so it is important to find out the homing end, and start homing to find the home sensor's origin (step S28) to determine whether the transfer is over. If it is checked (step S29) or the end of transfer is checked continuously, the end of the transfer, i.e., the end of homing may be applied to the same algorithm as the end of transfer detection. The transfer end algorithm checks whether the transfer end number is greater than 4 by using 4 times (step S30), and checks the transfer end when it is greater than 4, and executes the next operation that has stopped execution if it is 4 or less (step S31).

FIG. 16F is a flowchart illustrating dicing pauses in an automatic cutting method of a printed circuit board. FIG. The automatic and manual modes are divided into initial feed, X axis down, X axis cut, Y index, Z axis down, Z axis cut, and each axis homing, and are programmed to loop according to the data. Each part is programmed to run the cutting water at the time of cutting, the processing ramp at the start of the cutting, and the standby lamp at the end of the operation. The transfer of the table is operated by a transfer algorithm, the homing is used by the homing algorithm, the cutting water and the operation of the beacon etc. are used by the digital output algorithm. In the case of a diagonal index, two axes XY are programmed to move at the same time, and a dicing pause is used to stop the motion by pausing. The dicing pause is generated when the pause button is pressed to check the machining state during the processing (steps S33, S34, S36) (step S35), the cutting water is temporarily turned off, and then the Z axis is returned to the origin (step S37). If it goes to and restarts again (step S38), it moves to the position before pause (step S39), and continues the operation which proceeded from that position (step S40). The dicing pause is generated by pressing the pause button during machining, and the machining continues by pressing the button again (step S47).
