Description of the invention: ψ [Technical field to which the invention pertains] ' The present invention relates to a method and method for detecting a type of inspection, a special wealth and a tool detection system and method. [Prior Art] When the printed circuit board is replaced by a tool, the operator needs to perform two measurement processes. That is, I first make a tool for the tool, and the tool is the tool pointed by the controller, and then the tool. The yaw value is measured to determine whether the tool is eccentric. If the tool diameter does not match, you need to change the tool. If it is found that the tool is yawed, it is necessary to loosen the tool tool to solve the problem, or check the main reduction shirt of the printed circuit board drilling machine, and adjust it accordingly to avoid the tool yaw. Error, resulting in higher machining accuracy. Both of the above measurement steps are performed by a tool measuring instrument, which wastes a lot of work time and leads to inefficient processing. [Summary of the Invention] ❿ Contents, it is necessary to provide __ a fast tool system and method to save working time and improve processing efficiency. A tool inspection m is used for detecting a tool of a machine tool, the tool detection system comprising: a recording device and a controller, the laser sensor comprising a transmitter and a receiver, the transmitter for using a first frequency Transmitting a laser signal, the control thief is used to determine the freshness of the laser signal received by the receiver during the up and down movement between the transmitter (4) and the receiving n, and the frequency of the (4) laser signal received by the receiver is less than the The position of the tool is recorded as the first position, and the position of the tool is recorded at the instant when the frequency of the wrong signal received by the receiver is equal to zero. • The first position, and the first according to the s The coordinate difference between the position and the second position to determine whether the tool is yawed. A tool detecting method comprises the following steps: moving a spindle of a machine tool to move a tool of the machine tool to a position directly above a sound sensor/shell device, and controlling a spindle speed of the tool machine to reach a preset Speed, wherein the β hai iron sensor includes a transmitter and a receiver; 透过 through the control - the transmission of the n [the first fresh emission - Lin signal; the spindle of the machine tool is gradually moved down, the control off Breaking the frequency at which the receiver receives the mis-signal signal, when the frequency at which the receiver receives the mis-signal signal is less than the first frequency, the controller records the position of the tool as the first position at this time; The spindle of the machine continues to move down, and the controller continues to determine the frequency at which the receiver receives the tearing number. When the frequency at which the receiver receives the laser signal is equal to zero, the controller records the position of the tool as a second position; • the controller calculates a coordinate difference between the first and second positions in the vertical direction, the controller determines whether the difference ~ is close to zero, and if the difference ^ does not approach zero, then the judgment The knife at this time Detecting the occurrence of deflection and ends; ~ and if the difference approaches zero, it is determined that at this time the tool does not occur yaw. The tool inspection method, the method and the method for transmitting the riding signal to the tool through the transmitting H and calculating the position of the tool through the controller to calculate the frequency of the surface receiving signal, can quickly perform the tool Inspection saves processing time and improves processing efficiency. 5 201028242 [Embodiment] Please - and _ 1 and ® 2, the preferred embodiment of the tool inspection system of the present invention is used for the detection - printed circuit board drilling machine! Whether the tool 1 产生 has a yaw during the machining process is also used to detect whether the tool radius of the tool 10 is set correctly. The tool inspection system includes - a laser sensor 12 and - control _ 14.12 including - transmitting II 12G and - receiving H 122. The controller 14 includes a processing unit 14A and a memory unit 142. The machine for riding the road board is further provided with a recess 16 s s launcher 12 〇 and a receiver 122 correspondingly disposed at both ends of the recess 16 . The processing unit 140 emits a laser signal at a first frequency of the control signal, and calculates a frequency at which the transmitter 12 transmits the first frequency of the error signal and the receiver 122 receives the laser signal. It is also used to calculate the complex position (coordinate value) of the tool 1〇. The memory unit 142 is used to store the complex position of the tool 1〇. Referring to Fig. 3, a preferred embodiment of the tool detecting method of the present invention comprises the following steps: Step S1: After the printed circuit board drilling machine 1 replaces the tool 1 , the printed circuit board drilling machine 1 is started. Step S2: moving the tool 1〇 directly above the groove 16 by controlling the printed circuit board drilling machine i, and starting the spindle of the printed circuit board drilling machine i to start rotating to drive the tool 1〇 also starts Rotate and check if the spindle speed of the printed circuit board drilling machine reaches a preset measurement speed. If the spindle speed of the printed circuit board drill i has not reached its preset measurement speed, wait. If the printing circuit 201028242. The drilling speed of the board is reduced to 1 and the speed of the inspection is reached, the job step is. . . , the tool 10 is located on the vertical bisector of the line connecting the transmitter 120 and the receiver 122. Step S3: The laser sensor 12 is turned on by the controller 14 to cause the transmitter 120 to emit the laser signal at a first frequency. At this time, the frequency at which the receiver m receives the laser signal is equal to the first frequency. Step S4: The main axis of the printed circuit board drilling machine 1 is gradually moved downward along the z-axis direction of FIG. 2, and the processing unit 14 is operated by the receiver I22 to receive the recorded signal. And the listening signal, when the frequency of the laser signal received by the receiver 122 is just less than the first frequency, the processing unit 140 calculates the position of the tool 10 at this time, and records it as the first position a, and It is stored in the memory unit 142. At this time, the mis-signal signal emitted by the transmitter 12 is just touching the tool 10. Step S5: The processing unit 14 continues to determine that the ❿ 射 红 红 由 由 由 , , , , , , , , , , , , 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 122 And store it in the memory unit M2. At this time, the laser signal emitted by the transmitter 12 is all in contact with the tool 1〇. Step S6: The processing unit 14() calculates the coordinate difference 〜 of the first and second positions & and b in the z-axis direction. Step S7 · The processing unit 14 determines whether the difference ^ is close to zero. Step S8: If the difference value ~ is close to zero, that is, when the wrong signal sent by the transmitter (10) contacts the tool 1 ,, the laser is also moved at the same time as the tool 10 turns 7 201028242 All the contact with the tool 1 〇 'in this case means that the tool 1 〇 is in the process of rotation. The yaw occurs again, that is, the tool 10 coincides with the axis at all positions during the rotation', and then step S10 is performed. Step S9: If the difference value ~ does not approach zero, that is, when the laser signal emitted by the transmitter 12 is just touching the tool 10, the laser cannot simultaneously contact the laser tool during the rotation of the tool button. The tool 10, which means that the tool 1〇 is yawed during the rotation, that is, the axis of the tool 10 at all positions during the rotation is not coincident, the tool detection method ends, and the operator needs to stop and adjust. Step S10: The spindle of the printed circuit board drilling machine i continues to move down the z-axis by a preset distance m, which is smaller than the height of the tool 10. Step S11: The spindle of the printed circuit board drilling machine i stops moving downward, and the processing unit 140 calculates the position of the tool 1 at this time, and records it as the third position c, and stores it in the memory early element 142. At this time, since the tool 1〇 does not yaw during the rotation, the laser signal emitted by the transmitter 120 contacts the positive intermediate position of the tool 1 , that is, the axis position of the tool 10 . Step S12: The spindle of the printed circuit board drilling machine 1 is gradually translated forward along the γ axis in Fig. 2. Step S13: The processing unit 140 determines whether the receiver 122 receives the laser signal transmitted by the transmitter 120. If the receiver 122 does not receive the laser signal, that is, the frequency at which the receiver receives the laser signal is zero, the spindle of the printed circuit board drilling machine 1 continues to translate forward along the Y axis; if the receiver 122 receives To the laser signal 'that is, the frequency at which the receiver 122 receives the laser signal is not zero, then the terminal 201028242 proceeds to step S14. Step S14: The processing unit 14 calculates the position of the tool 10 at the moment when the receiver 122 receives the laser signal, that is, the moment when the receiver 122 receives the frequency of the laser signal is not zero, and records it as the fourth position. d and stored in the memory unit 142. Step S15: the processing unit 14 calculates the seat value r of the third and fourth positions c and d in the γ-axis direction. At this time, since the tool 1 () is not repaired during the rotation, the yaw is generated. When the tool 10 is in the third position c, the laser 12 of the transmitter 12 is mismatched; when the force 1 () is at the fourth position d, the transmitter 120 emits The recording signal has just not touched the edge of the tool (10), so the coordinate difference r represents the spread of the tool, so that the diameter of the tool 10 is 2r. Step S16: The processing unit 140 determines whether the tool diameter set in the drilled board of the printed circuit board is equal to 2r. _ Step S17: If the set tool diameter is equal to 2r, it is known that the selected tool 10 is selected correctly at this time, and the detection is completed. Step Si8: If the set tool diameter is not equal to 2r, it is known that the selected tool 10 is not in the normal state at the time, the detection is completed, and the operator needs to stop the tool change. The step S12 t can also control the spindle of the printed circuit board iron hole machine i to gradually move backward in the γ axis direction. If the receiver 122 does not receive the wrong signal, the printed circuit board drilling machine 1 Continue to move backward; if the receiver 122 receives the clock signal, step S14 is performed. 201028242 • The tool detection system and method of the month 1J illustrate the simultaneous detection of whether the 77 10 is yaw* and the tool radius of the tool is measured. The tool detection system and method can also be used to detect the tool separately. 1〇 Whether yaw is generated or the tool is measured. In the present embodiment, the tool detecting system and method are applied to the tool 1G of the printed circuit board drilling machine 1 as a limping. In other embodiments, the tool detecting system and method can also be used to detect tools of other machine tools. The tool detection system and method transmit a mis-signal signal to the tool 1〇' through the transmitter 12, and calculate the frequency at which the receiver (4) receives the mis-signal signal through the processing unit 14 and the tool is 〇 The position is calculated, so that the tool 10 can be quickly measured whether the yaw is generated during the JL process and whether the tool path of the tool has an error, which saves the processing _ and improves the processing efficiency.
