Description

测试PCB钻铣削温度的红外热像仪定位装置及定位方法 Infrared testing PCB positioning apparatus and a positioning method of drilling Milling Temperature

技术领域 FIELD

[0001] 本发明涉及机加工领域,更具体的说,涉及一种测试PCB板钻铣削温度的红外热像仪定位装置及定位方法。 [0001] The present invention relates to the field of machining, more particularly, to a test temperature of PCB milling drill infrared camera positioning device and positioning method.

背景技术 Background technique

[0002] 在PCB制造业中,虽然已发展出各种不同的孔径加工工艺,但目前仍有90%以上的PCB板是通过切削加工制成。 [0002] In manufacturing PCB, although a variety of different pore sizes developed processing technology, but there are still more than 90% of the PCB are formed by cutting. 在切削过程中,机床做功转换为切削热,这些切削热除少量逸散到周围介质中以外,其余热均传入刀具、切屑和PCB板中,刀具、PCB板和机床温升将加速刀具磨损,损坏PCB内部线路,严重时甚至引起刀具断裂报废加工的PCB板材。 During the cutting process, machine cutting work is converted to heat, in addition to a small amount of cutting heat which escapes into the surrounding medium, the rest of the incoming hot isostatic tool, chip and the PCB, the tool, PCB board and machine tool wear will accelerate the temperature rise , damage to the internal wiring PCB, causing serious or even scrap processing tool breakage PCB material.

[0003] 测定切削加工的温度的方法有很多种,现有的方法中,以红外热像仪较为突出。 [0003] There are many ways of measuring the temperature of cutting, the conventional method, the infrared camera is more prominent. 红外热像仪通过光机扫描机构探测工件(或刀具)表面辐射单元的辐射能量,并将每个辐射单元的辐射能量转换为电子视频信号,通过对信号进行处理,以可见图像的形式进行显示, 显示的热像图代表被测表面的二维辐射能量场,若辐射单元的表面辐射率已知,则可通过斯蒂芬-波尔兹曼定律求出辐射单元表面的温度分布场及动态变化。 Infrared radiant energy detecting the workpiece (or the tool) surface of the radiating element by a ray scanning mechanism, and converts the radiant energy of each radiating element is an electronic video signal, by processing signals for display as a visible image , two-dimensional radiation heat energy field as shown in FIG representative of the sensed surface, if the surface emissivity of the radiating element is known, by Stephen can - temperature distribution field radiating unit and dynamics determined surface Boltzmann's law. 红外热像仪测温法具有直观、简便、可远距离非接触监测等优点,在恶劣环境下测量物体表面温度时具有较大优越性。 Infrared thermometry is intuitive, simple, non-contact distance can be monitored, etc., having a large surface temperature measured superiority in harsh environments. 但是,红外热像仪的镜头需要准确定位到检测刀具(或是工件)上才能得到更准确的温度值,若是在定位中存在误差,将影响测定温度值的精确度。 However, the infrared camera lens must be accurately positioned to detect the tool (or workpiece) in order to obtain a more accurate value of the temperature, if there is an error in the positioning, will affect the accuracy of temperature measurement.

[0004] 在PCB加工领域,加工PCB板的刀具多为硬质合金微型刀具,不同加工参数、不同加工板材、不同PCB盖板用硬质合金微型刀具加工时产生的热量不同,加工时温度过高容易对加工刀具和PCB板造成不利影响,因此对微型刀具的实时温度的监测将尤为重要,对于微型刀具,红外热像仪的定位难度也较高。 [0004] In the field of processing of PCB, the PCB tooling plurality of micro-carbide cutting tools, different processing parameters, the different sheet metal processing, different from the heat generated during machining carbide PCB cover different micro-tool, machining temperature is too highly likely to cause adverse effects on the machining tool and the PCB, so real-time temperature monitoring of micro-tool will be particularly important for micro-tool, infrared camera positioning and more difficult. 目前,红外热像仪一般通过三脚架进行定位, 如图1所示,红外热像仪的定位装置包括:三脚架15、与三脚架15通过铰链连接的支撑架16,以及与支撑架16通过铰链连接的吊架17,而红外热像仪9则固定在与吊架17相连的旋台7上。 Currently, the infrared camera is generally positioned by the tripod, shown in Figure 1, the infrared camera positioning apparatus comprising: a tripod 15, the support frame 15 and the tripod 16 is connected by a hinge, and a support frame 16 is connected by a hinge hanger 17, and the infrared camera 9 is fixed on a rotary table 177 attached to the hanger. 支撑架16及吊架17的延伸较长,通过调整支撑架16及吊架17的角度及高度来实现红外热像仪9的位置定位比较困难,测试过程中机床主轴会发生移动,红外热像仪不仅需移动调整位置,影响定位的精度,还很难调整高度和角度使两个参数相互配合达到准确重复定位。 And the support frame 16 is elongated in the hanger 17, the position of the infrared camera positioned to achieve 9 more difficult, during the test spindle will move the infrared thermal image occurs by adjusting the angle and height of the support frame 16 and the hanger 17 need only adjust the position of the mobile device, affect the accuracy of the positioning, but also difficult to adjust the height and angle of the two parameters with each other to achieve accurate repeatability.
