Abstract

The invention discloses a method for detecting a main shaft cutter of a PCB (printed circuit board) processing machine, which comprises the following steps: providing a detection base, wherein the detection base and the main shaft are respectively conducted with direct current power supplies with different polarities, and the center of the detection base is an initialization measurement zero point; the main shaft clamps the cutter displacement and touches both sides of the detection base, the platform displacement mechanism is utilized to drive the main shaft to displace, so that the cutter clamped by the main shaft can touch both sides of the detection base, the detection base and the main shaft which are conducted with different polarities respectively generate a signal at two touch points, the signal is transmitted to the processing software calculator to be operated, and the signal is recorded into a direction relative value which is compared with the preset cutter size and exceeds the allowable range of the cutter size radius to be set, and an error detection warning is generated; the relative position values of the two sides of the tool displacement touch detection base are interpreted to calculate the size of the tool clamped by the spindle, if the size of the tool is in accordance with the size range of the tool to be processed, the processing operation is carried out, and if the size of the tool exceeds the allowable range of the tool to be set, an error detection warning is generated.

Description

PCB processing machine main axle cutter detection method

Technical field

The present invention relates to a kind of PCB processing machine main axle cutter detection method, be meant a kind of size of main shaft cartridge clip cutter and method of error detection caution of detecting especially.

Background technology

The PCB processing machine is when the processing operation at present, it is previous prepares cutter needs with machining software sets cutter size and conforms to and begin to process operation, the measure that right processing machine mechanism at present itself does not have a cover to cooperate the machining software error detection to handle, therefore in the processing operation, still have artificial careless mistake factor and cause processing faulty materials or scrap, so the measure that the clamping of PCB processing machine main axle cutter detects is very important.

Summary of the invention

The purpose of this invention is to provide a kind of PCB processing machine main axle cutter detection method, to guarantee processing quality.

Above-mentioned purpose of the present invention is achieved in that a kind of PCB processing machine main axle cutter detection method, comprises the following steps:

Provide one to detect pedestal, this detects the dc source of pedestal and each conducting opposed polarity of main shaft, and order detection pedestal center is that initialization measures zero point;

Main shaft clamping tool displacement is touched and is detected the pedestal both sides, to utilize the platform displacement mechanism to drive the main shaft displacement, main shaft clamping cutter is touched detect the pedestal both sides, make the detection pedestal and the main shaft of conducting opposed polarity respectively touch generation one signal in two, and successively transfer to and carry out computing in the machining software calculator, and be recorded as an orientation relative value and another orientation relative value respectively, for comparing with predefined tool dimension, exceed desire and set the radius allowed band of tool dimension, produce error detection caution; Described orientation relative value and another orientation relative value are equal to detection pedestal radius and add tool radius;

Carry out tool displacement and touch the orientation relative value interpretation that detects the pedestal both sides,, promptly process operation, exceed desire and set the tool dimension allowed band, promptly produce error detection caution if meet desire process tool size range to calculate main shaft clamping tool dimension.

For the ease of further understanding above-mentioned order of the present invention, characteristics and technique effect, the present invention is described in detail with instantiation below in conjunction with accompanying drawing.

Description of reference numerals: detect pedestal 1; Main shaft 2; Cutter 3.

The specific embodiment

At first, see also Fig. 1 to Fig. 3, wherein Fig. 1 is the process block diagram of detection method of the present invention, and the step of its Cinematographic process comprises:

First step provides one to detect pedestal 1, and this detects the dc source of pedestal 1 and main shaft 2 each conducting opposed polarity, and to make this detect pedestal 1 center be that initialization measures zero point.Be the anodal dc source of conducting if detect pedestal 1, this main shaft 2 is conducting negative pole dc source, otherwise, detect pedestal 1 and be conducting negative pole dc source, then main shaft 2 is the anodal dc source of conducting.

Second step, 3 displacements of main shaft 2 clamping cutters are touched and are detected pedestal 1 both sides, at first utilize the platform displacement mechanism to drive main shaft 2 and do displacement, main shaft 2 clamping cutters 3 are touched detect pedestal 1 one sides, make the detection pedestal 1 of conducting opposed polarity can produce a signal with main shaft 2, and transfer to and carry out computing in the machining software calculator, and be recorded as an orientation relative value (this orientation relative value equals to detect pedestal 1 radius and adds 3 radiuses of fixing a cutting tool), for comparing with predefined tool dimension, exceed desire and set the radius allowed band of tool dimension, promptly produce error detection caution (as shown in Figure 2), utilize the platform displacement mechanism to drive main shaft 2 again and do displacement, main shaft 2 clamping cutters 3 are touched detect pedestal 1 opposite side, make the detection pedestal 1 of conducting opposed polarity can produce another signal with main shaft 2, and transfer in the machining software calculator and do computing, and be recorded as another orientation relative value (this another orientation relative value also equals to detect pedestal 1 radius and adds 3 radiuses of fixing a cutting tool), and compare with predefined cutter 3 sizes, exceed desire and set the radius allowed band of cutter 3 sizes, promptly produce error detection caution (as shown in Figure 3).

Third step, carry out cutter 3 displacements and touch the orientation relative value interpretation that detects pedestal 1 both sides,, meet desire process tool 3 size ranges and promptly process operation to calculate main shaft 2 clamping cutters 3 sizes, exceed desire and set cutter 3 size allowed bands, promptly produce error detection caution.

In sum, PCB processing machine main axle cutter detection method provided by the present invention, really can reach size and error detection caution that expection detects main shaft cartridge clip cutter, and checkout gear equipment is simple, the procuring equipment cost also reduces relatively, and can mate the error detection processing mode of calculation with machining software, and impel cutter to detect more to become to simplifying easily, overcome artificial careless mistake factor fully and cause processing faulty materials or scrap.
