Description

可設定恆速運轉之切割機以及配置切割機結構之方法Cutting machine that can be set to run at a constant speed and method for configuring the structure of the cutting machine

本發明係關於一種可設定恆速運轉之切割機，尤其是指利用一人機介面設定一恆速轉速來控制馬達之轉速，並且在該人機介面顯示該馬達之運轉轉速以及運轉功率或者其他的運轉資訊。The present invention relates to a cutting machine that can be set to run at a constant speed, especially to use a man-machine interface to set a constant-speed rotating speed to control the rotating speed of a motor, and display the running speed and power of the motor on the man-machine interface. Operation information.

目前市面上之切割機，皆使用有刷馬達來做為切割機的驅動馬達，而有刷馬達具有體積過大、重量重，而導致切割機無法隨身攜帶等問題，且有刷馬達無法輕易地改變轉速來切割，若要調整有刷馬達的轉速來進行切割，需外接一個利用控制電流量的方式的調速裝置才能進行調整有刷馬達之轉速，據此，有刷馬達會造成生產時，配裝上的規劃問題。At present, the cutting machines on the market all use a brushed motor as the driving motor of the cutting machine. However, the brushed motor is too large and heavy, so that the cutting machine cannot be carried around, and the brushed motor cannot be easily changed. If the speed of the brushed motor is to be adjusted for cutting, it is necessary to connect a speed control device that controls the amount of current to adjust the speed of the brushed motor. Mounted planning issues.

再者，上述之固定轉速或者是調整後的轉速，皆為空載時的轉速，每當切割機進行切割時，馬達必然會受到待切材料的阻力影響，此時馬達之運轉轉速(負載轉速)必然下降，造成切割的效率不佳，更導致可能無法切斷材料，而市面上的可攜帶式切割機皆無安裝資訊輸出介面提供運轉資訊，讓使用者通常只能藉著自身的經驗控制驅動手把下壓的力道或鋸片的速度，來增加切割的流暢度進行切割，而無經驗之使用者既無法藉自身經驗來控制力度，更無法順暢地切斷待切材料，而上述兩使用者之操作，也都不易判斷該切割時的力度，造成操作上的困難。Furthermore, the above-mentioned fixed rotational speed or adjusted rotational speed are all rotational speeds at no-load. Whenever the cutting machine is cutting, the motor will inevitably be affected by the resistance of the material to be cut. At this time, the operating speed of the motor (load speed ) will inevitably decrease, resulting in poor cutting efficiency, and may not be able to cut the material, and the portable cutting machines on the market are not equipped with an information output interface to provide operation information, so that users can usually only control the drive based on their own experience. The pressing force of the handle or the speed of the saw blade increases the smoothness of the cutting, and inexperienced users can neither control the force with their own experience, nor can they cut the material to be cut smoothly. It is also difficult to judge the strength of the cutting process, resulting in operational difficulties.

另外，在切割時，因使用者不知切割機操作是否已達額定輸出功率，若達額定輸出功率，使用者仍持續操作時，恐造成馬達的燒毀。In addition, during cutting, because the user does not know whether the operation of the cutting machine has reached the rated output power, if the rated output power is reached, if the user continues to operate, the motor may be burned.

據此，本發明希望提供一種能夠克服上述缺點的可設定恆速運轉之切割機以及配置該切割機結構之方法。Accordingly, the present invention wishes to provide a cutting machine capable of setting constant speed operation and a method for configuring the structure of the cutting machine which can overcome the above-mentioned disadvantages.

To adjust the constant speed of the motor, it is no longer necessary to judge the cutting force by your own experience, so as to achieve the effect of convenient operation and energy saving.

本發明的次要目的為利用一補償電流，提供額外的功率於因受到待切材料的阻力影響而下降的負載轉速，其方法是先經由控制模組預先輸入一恆速轉速設定值，該控制模組會計算因阻力影響而下降的轉速還需增加多少的轉速之功率，輸出對應之補償功率到馬達，該馬達因補償功率的添加，使負載轉速能保持一樣於空載轉速，使切割時能保持一定切割力道。The secondary purpose of the present invention is to use a compensation current to provide additional power to the load speed reduced by the resistance of the material to be cut. The module will calculate how much the power of the rotating speed needs to be increased for the speed reduced by the resistance, and output the corresponding compensation power to the motor. Due to the addition of the compensation power, the motor can keep the load speed the same as the no-load speed, so that when cutting Can maintain a certain cutting force.

本發明的另一次要目的為預設一最大功率限制，控制模組會根據馬達之電流信號與電壓信號，進行計算運轉功率，若運轉功率等/大於該最大功率限制，則會於發出警報，提醒使用者過度的操作，而使切割機燒毀。Another secondary purpose of the present invention is to preset a maximum power limit, the control module will calculate the operating power according to the current signal and voltage signal of the motor, if the operating power is equal to/larger than the maximum power limit, an alarm will be issued, Remind the user that excessive operation may cause the cutting machine to burn out.

依據步驟S13，檢測單元62會檢測該馬達40運轉時的電流以及電壓，並產生一電流信號以及一電壓信號回授至該微處理單元61。依據步驟S14，該微處理單元61能根據該電流信號，計算該馬達40即時之運轉轉速。依據步驟S15該微處理單元61將該運轉轉速的數值顯示於該人機介面50之顯示部分52上。依據步驟S16，該微處理單元61會依據該輸入之恆速轉速值，計算以保持該馬達40恆速運轉所需增加或減少之補償功率，並控制該驅動單元63輸出該補償功率給該馬達40，使該馬達40之運轉轉速維持於該恆速轉速值。According to step S13 , the detection unit 62 detects the current and voltage when the motor 40 is running, and generates a current signal and a voltage signal to feed back to the micro-processing unit 61 . According to step S14, the micro-processing unit 61 can calculate the real-time running speed of the motor 40 according to the current signal. According to step S15 , the micro-processing unit 61 displays the numerical value of the running speed on the display portion 52 of the man-machine interface 50 . According to step S16, the micro-processing unit 61 calculates the compensation power to be increased or decreased to keep the motor 40 running at a constant speed according to the input constant-speed rotational speed value, and controls the drive unit 63 to output the compensation power to the motor 40, maintaining the running speed of the motor 40 at the constant speed value.

依據步驟S17，該微處理單元61能根據該電壓信號與電流信號，計算該馬達40之一運轉功率。依據步驟S18，該微處理單元61將該運轉功率的數值顯示於該人機介面50之顯示部分52上。依據步驟S19，該微處理單元61已為驅動單元63預先設置一個最大輸出功率限制，當該驅動單元63的輸出功率高過所預設之最大功率限制時，該微處理單元61會輸出警示信號於該人機介面50之顯示部分52，進行警示於使用者(例如:螢幕閃爍、顯示警語或警示聲等等)，讓使用者能得知若繼續進行切割，勢必會造成該馬達40損毀。According to step S17, the micro-processing unit 61 can calculate an operating power of the motor 40 according to the voltage signal and the current signal. According to step S18 , the microprocessor unit 61 displays the value of the operating power on the display portion 52 of the man-machine interface 50 . According to step S19, the microprocessor unit 61 has preset a maximum output power limit for the drive unit 63, and when the output power of the drive unit 63 exceeds the preset maximum power limit, the microprocessor unit 61 will output a warning signal On the display part 52 of the man-machine interface 50, a warning is given to the user (for example, the screen flashes, a warning message or a warning sound is displayed, etc.), so that the user can know that if the cutting continues, the motor 40 will be damaged. .

此外，藉由該啟動開關212或該馬達40的開啟以及關閉，該微處理單元61切換該顯示部分52的顯示模式，例如該啟動開關212或該馬達40為關閉時，該微處理單元61控制顯示部分52顯示恆速轉速設定之設定頁面，若啟動開關212或該馬達40為開啟時，該微處理單元61控制顯示部分52顯示及時的空載轉速、負載轉速，又或者電流、電壓、輸出功率、消耗功率，其中上述之參數皆可不同方式組合。另外，操作輸入部分51也能以手動方式使該微處理單元61控制顯示部分52切換複數個顯示頁面，而分別顯示前述之所有或部分參數，讓使用者能夠藉由該顯示部分52得知該空轉轉速是否為所輸入之恆速轉速值或者切割機的使用情況等等。In addition, by turning on and off the start switch 212 or the motor 40, the micro-processing unit 61 switches the display mode of the display part 52. For example, when the start switch 212 or the motor 40 is turned off, the micro-processing unit 61 controls The display part 52 displays the setting page of constant speed speed setting. If the start switch 212 or the motor 40 is turned on, the microprocessor unit 61 controls the display part 52 to display the no-load speed, load speed, or current, voltage, output Power, power consumption, the above parameters can be combined in different ways. In addition, the operation input part 51 can also manually make the micro-processing unit 61 control the display part 52 to switch a plurality of display pages, and display all or part of the aforementioned parameters respectively, so that the user can know the parameters through the display part 52 . Whether the idling speed is the input constant speed speed value or the usage of the cutting machine, etc.

當進行切割時，依據驅動手把200所界定之方向，使用者下壓驅動手把200進而帶動側邊之鋸片30位移至待切割物之位置，進行切割，此時因受到待切割物之切割時阻力的影響，該馬達40之轉速必然會減少(以下因阻力影響而下降之轉速都簡稱為:負載轉速)，例如從1300rpm大幅下降至1000rpm等，進而造成切割效率的不良，依據步驟S13，此時檢測單元62會檢測該負載轉速下馬達40運轉的電流與電壓，並產生一電流信號與一電壓信號於該微處理單元61，依據步驟14或步驟S17，該微處理單元61根據該電壓信號與該電流信號，計算馬達40即時的運轉轉速或運轉功率。When cutting, according to the direction defined by the driving handle 200, the user depresses the driving handle 200 and drives the side saw blade 30 to move to the position of the object to be cut for cutting. Due to the influence of resistance during cutting, the rotational speed of the motor 40 will inevitably decrease (the rotational speed of the motor 40 will be reduced due to the influence of resistance hereinafter referred to as load rotational speed), for example, from 1300 rpm to 1000 rpm, etc., thereby causing poor cutting efficiency, according to step S13 , at this time, the detection unit 62 will detect the current and voltage of the motor 40 running at the load speed, and generate a current signal and a voltage signal to the micro-processing unit 61, according to step 14 or step S17, the micro-processing unit 61 according to the The voltage signal and the current signal are used to calculate the real-time running speed or running power of the motor 40 .

在本發明之較佳實施例中，該馬達40採用無霍爾無刷直流電馬達，透過微處理單元61控制驅動單元63的佔空比來控制該馬達40之恆速轉速，例如： 基於該馬達40之100%的額定功率，該微處理單元61控制該驅動單元63只使用約60%的功率來驅動馬達40運轉在設定的恆速轉速，當該馬達40切割時遇到阻力使轉速減少時，該微處理單元61會控制該驅動單元63將其餘的40%功率補上，使該馬達40在遇到阻力的情況下，能夠保持運轉轉速為所輸入之恆速轉速值。當切割硬度較大或者厚度較大的材質時，為了維持該馬達40之恆速轉速，該微處理單元61會控制驅動單元63，進而加大維持恆速之補償功率。In a preferred embodiment of the present invention, the motor 40 adopts a Hallless brushless DC motor, and the duty cycle of the driving unit 63 is controlled by the microprocessor unit 61 to control the constant speed of the motor 40, for example: Based on the motor 40 to 100% of the rated power, the microprocessor unit 61 controls the drive unit 63 to use only about 60% of the power to drive the motor 40 to run at the set constant speed, when the motor 40 encounters resistance when cutting and reduces the speed , the micro-processing unit 61 will control the driving unit 63 to make up the remaining 40% of the power, so that the motor 40 can keep the running speed at the input constant speed value when encountering resistance. In order to maintain the constant speed of the motor 40 when cutting materials with greater hardness or greater thickness, the micro-processing unit 61 controls the drive unit 63 to increase the compensation power for maintaining the constant speed.
