如图16至图18所示,根据本公开实施例的自动称重断胶装置6a包括:称重防风装置2b,称重防风装置2b内限定有第一容纳腔;称重装置1b,称重装置1b设于第一容纳腔内;流体分段装置4b,流体分段装置4b设于称重防风装置2b的上方,流体分段装置4b具有第二容纳腔,第二容纳腔与第一容纳腔相连通;流体接收容器3b,流体接收容器3b设于第二容纳腔内,流体接收容器3b位于称重装置1b的上方,流体接收容器3b具有断胶和称重两种状态,流体接收容器3b位于断胶状态时,流体接收容器3b向上运动以接收胶水,流体接收容器3b位于称重状态时,流体接收容器3b向下运动并置于称重装置1b上,以对胶水进行称重。本公开结构简单,通过将称重装置1b和流体接收容器3b置于容纳腔内,确保了称重过程无干扰,利用流体分段装置4b对胶水进行分段,确保每次测量的点胶量更加精确。
根据本公开一个实施例,如图16所示,称重防风装置2b包括底板21和防风罩22。称重装置1b设于底板21的上表面;防风罩22盖设在称重装置1b的上方,且防风罩22与底板21的边缘密封连接,防风罩22的上端具有开口,流体分段装置4b设于开口上。

根据本公开一个实施例,如图18所示,流体分段装置4b还包括两个第一密封圈43和第二密封圈410,每个环形槽45b内均设有一个第一密封圈43;第二密封圈410设于密封罩47与密封底座411之间,通过设置第一密封圈43和第二密封圈410,确保了断胶和称重两个过程中,密封罩47和防风罩22内始终处于无风状态,避免了外界干扰,确保测量结果准确。

结合图30A和图30B,对本公开提供的贴装模块2进行解释说明。
图30A是本公开一个实施例中提供的贴装模块的结构示意图,图30B是本公开一个实施例中提供的贴装模块的剖视图,图30C是本公开一个实施例中提供的贴装模块的正面示意图,结合图30A至图30C所示,本公开提供的贴装模块b2可以包括负压供气组件、真空吸盘b21、角度调整组件、压力传感器b22、传动组件、传导杆b23、弹簧b24。
负压供气组件的气管接头b251与真空吸盘b21的进气口连通,以向真空吸盘b21提供负压。也就是说,负压供气组件通过气管接头b251向真空吸盘b21提供负压。
真空吸盘b21安装于传动组件的第一端,传动组件的第二端与弹簧b24的第一端相抵设置,弹簧b24的第二端与传导杆b23的第一端相抵设置,传导杆b23的第二端与压力传感器b22相抵设置。这样,当真空吸盘b21吸附散热盖之后,传动组件会通过弹簧b24向压力传感器b22传递压力,使压力传感器b22感知到真空吸盘b21对吸附的散热盖的压力值。
角度调整组件与真空吸盘b21传动连接,角度调整组件带动真空吸盘b21进行角度调节。也就是说,角度调整组件可以带动真空吸盘b21旋转,以调节真空吸盘b21与水平方向上的角度。比如,角度调整组件可以带动真空吸盘b21在360°的方位上进行角度调节。
在一种可能的实现方式中,负压供气组件可以包括气管接头b251、密封腔体b252、密封圈,其中:气管接头b251进入密封腔体b252,密封腔体b252与真空吸盘b21连通,密封腔体b252通过密封圈密封。

气管接头b251进入密封腔体b252,气管接头b251另一端连通至负载提供装置上,这样负载提 供装置会将负压通过气管接头b251导入至密封腔体b252内;又由于花键b26为中空结构,且在密封腔体b252内的部分设置有通孔,因此可以将密封腔体b252内的负压连通至真空吸盘b21,实现对真空吸盘b21的吸附控制。
可选的,花键b26上端与弹簧b24的第一端相抵,花键b26上下运动传递到弹簧b24上,弹簧b24形变产生的压力通过传导杆b23传递到压力传感器b22,也就是说,当真空吸盘b21吸附散热盖之后,花键b26会通过弹簧b24将压力传递到压力传感器b22,压力传感器b22感知压力的大小,从而可以对真空吸盘b21所吸附散热盖时产生的压力进行实时监控。
为了便于调节弹簧b24的初始压缩量,本公开提供的贴装模块b2还可以包括预压力调节座b27,预压力调节座b27安装于压力传感器b22上方,以用于调节弹簧b24的初始压缩量。

皮带套设于第一同步轮b283和第二同步轮b285上,传动套b286套设固定于传动组件的花键b26上。
当传动组件包括上述的花键b26时,这里所讲的传动套b286通常是指花键b26套。
在实际应用中,通常还需要对皮带进行张紧,为了便于调节皮带的张紧度,角度调整组件还可以包括皮带张紧螺丝b288,皮带张紧螺丝b288用于调节皮带的张紧力。
通常,贴装模块b2的吸附面在安装之后可能是倾斜的,为了保证工艺要求,本公开中提供的贴装模块b2还可以包括调平组件,调平组件与真空吸盘b21传动连接,以调节真空吸盘b21的水平角度。

一般来讲,取料定位部b32位于上料部b31和下料部b33之间,以减少第一横移组件b34的移动 行程,且空间排布简单,空间利用率高。
在一种可能的实现方式中,上料部b31可以包括第一顶升板b32、顶升定位传感器b312和第一顶升组件b313,第一横移组件b34包括夹紧气缸和夹块b342。其中,第一顶升组件b313的顶升端上安装第一顶升板b32,第一顶升板b32上方用于承载散热盖承载件b35;夹紧气缸的驱动端与夹块b342连接,以驱动夹块b342开合;第一顶升组件b313顶升散热盖承载件b35到传感器处,夹紧气缸带动夹块b342夹紧散热盖承载件b35。
这里所讲的顶升定位传感器b312可以是光电传感器等,光电传感器通常包括相对安装的光线发射器和光线接收器,当散热盖承载件b35被顶升至光线发射器和光电接收器之间时,光线接收器会产生变化的电信号,从而判定散热盖承载件b35被顶升至光电传感器位置。
可选的,第一顶升组件b313可以包括第一顶升电机b3131、第一顶升导轨b3132和第一顶升丝杠b3133,第一顶升板b32通过第一滑块b3134安装于第一顶升导轨b3132上,第一顶升丝杠b3133安装于第一顶升电机b3131和第一顶升板b32之间,第一顶升电机b3131通过第一顶升丝杠b3133带动第一顶升板b32沿着第一顶升导轨b3132上下移动。
在实际应用中,散热盖承载件b35可以是承载散热盖的Tray上料板b3,也可以承载散热盖的弹夹。
以散热盖承载件b35为Tray上料板b3为例,上料部b31的Tray上料板b3位于第一顶升板b32上方,Tray上料板b3上承载散热盖,第一顶升组件b313通过第一顶升板b32顶升Tray上料板b3,以将Tray上料板b3顶升至顶升定位传感器b312位置处;上料部b31还包括第一横向滑轨b314,Tray上料板b3在外力作用下沿着第一横向滑轨b314上料至第一顶升板b32的正上方。
为了便于操作人员对Tray上料板b3进行操作,可以在Tray上料板b3的端部固定安装有把手b36,操作人员通过操作把手b36作用于Tray上料板b3,以实现在第一横向滑轨b314上的抽拉,对应的,Tray上料板b3在外力作用(通常可以指操作人员的施力,当然也可以通过其他机械施力的形式)下沿着第一横向滑轨b314上料至第一顶升板b32的正上方。
取料定位部b32可以包括多个顶升定位块b321,第一横移组件b34还包括移动件b341、移动件b341驱动模组,夹块b342气缸固定安装于移动件b341上,移动件b341驱动模组驱动移动件b341转动,移动件b341带动夹紧气缸和夹块b342运动,以将夹块b342夹持的散热盖承载件b35移动至顶升定位块b321上方,顶升定位块b321上升插入至散热盖承载件b35的对应插孔,实现散热盖承载件b35的定位固定。
可选的,多个顶升定位块b321分别位于取料定位部b32的两端,以保证对散热盖承载件b35定位时的施力均衡,降低散热盖承载件35的角度偏移。
在散热盖承载件b35上的散热盖被取完后,移动件b341驱动模组驱动移动件b341转动,以将散热盖承载件b35移动至下料部b33,夹块b342打开将散热承载件释放至下料部b33。
这里所讲的移动件b341可以是皮带,对应的移动件b341驱动模组可以包括驱动器(比如电机等)、主动轮、从动轮,主动轮和从动轮分别间隔设置于上料部b31的外侧和下料部b33的外侧,驱动器的驱动端与主动轮连接,皮带缠绕于主动轮和从动轮上,驱动器驱动主动轮,以带动皮带在上料部b31和下料部b33之间转动。
这里所讲的移动件b341也可以是丝杠,对应的移动件b341驱动模组可以驱动电机,驱动电机的驱动端安装丝杠,驱动电机带动丝杠转动。
当散热盖承载件b35是Tray上料板b3时,由于散热盖通常是直接放置于Tray上料板b3上的,散热盖的上方或周边没有遮挡,取料头可以直接从Tray上料板b3上拾取散热盖。而在散热盖承载件b35为弹夹时,由于散热盖被装载于弹夹中,取料头在从弹夹中取料时,通常需要先将散热盖从弹夹中顶出或顶升至弹夹的上端部,以便取料头拾取散热盖。
为了兼容通过弹夹实现散热盖的上料方式,请参见图31C和图31D所示,本公开中提供的取料定位部b32还可以包括顶升上料组件b322,顶升上料组件b322包括上料电机b3221、上料丝杠b3222、顶升杆b3223、第二竖向导轨b3224和同步带,上料电机b3221与上料丝杠b3222上的丝杠螺母传动连接,顶升杆b3223安装于丝杠螺母上,丝杠螺母通过滑块安装于第二竖向导轨b3224上,上料电机b3221带动丝杠螺母沿着第二竖向导轨b3224向上运动,顶升杆b3223将弹夹内的散热盖顶升脱离弹夹。
仍旧参见图31A和图31B所示,下料部b33可以包括:第二顶升板b331和第二顶升组件b332,其中:第二顶升组件b332的顶升端上安装第二顶升板b331,第二顶升板b331上方用于承载取料后 的散热盖承载件b35;第二顶升组件b332带动第二顶升板b331上升或下降。
类似的,第二顶升组件b332可以包括第二顶升电机、第二顶升导轨和第二顶升丝杠,第二顶升板b331通过滑块安装于第二顶升导轨上,第二顶升丝杠安装于第二顶升电机和第二顶升板b331之间,第二顶升电机通过第二顶升丝杠带动第二顶升板b331沿着第二顶升导轨上下移动。
散热盖承载件b35为Tray上料板b3,下料部b33还可以包括第二滑轨b333,Tray上料板b3位于第二顶升板b331上方,第二顶升组件b332通过第二顶升板b331带动取料后的Tray上料板b3下降,以将Tray上料板b3放置于第二滑轨b333上,Tray上料板b3在外力作用下沿着第二滑轨b333移动,以从下料部b33抽出。
在实际应用中,以散热盖承载件b35为Tray上料板b3为例,首先,操作人员将Tray上料板b3放置于上料部b31,比如图31E中将Tray上料板b37推送至上料部b31的顶升板上,上料部b31的第一顶升组件b313将Tray上料板b37顶升至顶升定位传感器b312位置后,加紧气缸驱动夹块b342以夹住Tray上料板b37;然后横移模组通过移动件b341带动加紧气缸和夹块b342横移,进而实现将Tray上料板b37移动至取料定位部b32,如图31F所示,取料定位部b32的顶升定位块b321对Tray上料板b37进行定位;取料头从Tray上料板b37上拾取散热盖,在拾取完成后,横移模组继续将空的Tray上料板b37移动至下料部b33的第二顶升板b331上,如图31G所示。
若散热盖承载件b35为弹夹时,通常在弹夹移动至取料定位部b32并定位后,顶升上料组件b322会顶升弹夹内的散热盖,以便于取料头从弹夹内拾取散热盖。其余的工作流程均与Tray上料板b37类似。
本公开提供的散热盖承载件b3的上下料装置,通过设置横跨于上料部b3、取料定位部b3和下料部b3的第一横移组件b3,通过第一横移组件b3将在上料部b3上料的散热盖承载件b3移动至取料定位部b3进行取料,在取料完成后再通过第一横移组件b3将空的散热盖承载件b3输送至下料部b3进行下料,实现了散热盖承载件b3的自动上下料,避免了停机上料或停机下料的方式,为生产线的连续作业提供了保障。利用通过在取料定位部b3设置顶升上料组件b3,使得散热盖承载件b3的上下料装置可以兼容弹夹式上料的应用,满足了更多的使用需求。
综上所述,本公开提供的散热盖贴装装置,通过设置定位模块,可以对吸取的散热盖进行定位,然后再将散热盖装配至载板内的芯片上,提高了散热盖装配的精度。
另外,在设置贴装模块时,由于设置了角度调整组件,可以比较精确地调整真空吸盘的角度,可满足不同尺寸规格的散热盖贴装,通过设置压力传感器可以实时监控真空吸盘对吸附的工件的压力,实现贴装时的压力反馈,满足了工艺要求的同时,也避免了产品在装配过程中压坏的风险。
通过在输送轨道模块内设置横跨于上料部、取料定位部和下料部的第一横移组件,通过第一横移组件将在上料部上料的散热盖承载件移动至取料定位部进行取料,在取料完成后再通过第一横移组件将空的散热盖承载件输送至下料部进行下料,实现了散热盖承载件的自动上下料,避免了停机上料或停机下料的方式,为生产线的连续作业提供了保障。
图32是本公开一个实施例中提供的热压装置的结构示意图,本公开提供的热压装置可以包括检测部(图32中示出了第一检测部c100和第二检测部c101)、加热保压部c20和输送装置c30。
在一种可能的实现方式中,检测部为一个,检测部设置于加热保压部c20的前道工位或后道工位。
在另一种可能的实现方式中,如图32所示,检测部为两个,两个检测部分别设置于加热保压部c20的前道工位和后道工位,分别为第一检测部c100和第二检测部c101。
在实际应用中,可以根据分析需要将检测部设置在加热保压部c20的前道工位和/或后道工位。
在实际生产中,输送装置c30将装载有工件c50的载物治具c40输送至检测部和加热保压部c20。
检测部对工件c50上至少一处位置的工件额高度进行测量并对工件c50的外观进行检测。
这里所讲的工件额高度是指工件c50上一位置处的高度与载物治具c40上与位置相差预定距离位置处的高度之间的高度差值。
比如,在工件c50的一个位置A处的高度为Ha,载物治具c40上与该位置A相差预定距离位置处A’的高度为ha,则产生的一组工件额高度为△ha=ha-Ha。这里所讲的预定距离通常可以根据工件c50的尺寸来设定,一般来讲,用于计算工件额高度的工件c50上的位置以及载物治具c40上的位置之间距离非常接近,这样产生的计算误差会比较低。
加热保压部c20对位于加热保压部c20位置处的工件c50进行加热保压。
请参见图33所示,其是本公开一个实施例中提供的检测部的结构示意图,检测部可以包括第二横移组件c11、测高传感器头c12和AOI相机C13,测高传感器头c12和AOI相机C13安装于第二 横移组件c11上,并在第二横移组件c11的带动下在水平调节方向上移动,水平调节方向与输送装置c30的输送方向垂直。
测高传感器头c12对工件c50的预定位置处以及载物治具c40上与预定位置相差预定距离的位置处进行测高;AOI相机C13对工件c50的外观进行拍照检测。
在一种可能的实现方式中,如图32所示,检测部为两个,分别为位于加热保压部c20前道工位的第一检测部c100和位于加热保压部c20后道工位的第二检测部c101。
第一检测部c100可以对工件c50上至少一处位置的工件额高度进行测量并对工件c50的外观进行检测,得到第一组检测数据。
比如,测高传感器头c12对工件c50的3个位置(可以多个位置)进行测高(高度数据H1、H2、H3...),并对载物治具c40与工件c50测试点位置相近的点也进行测高(高度数据h1、h2、h3...),对于测试点就产生了工件额高度:(△h1、△h2、△h3...),其中△h1=h1-H1,△h2=h2-H2,△h3=h3-H3…。
第二检测部c101可以对工件c50上至少一处位置的工件额高度进行测量并对工件c50的外观进行检测,得到第二组检测数据。
比如,测高传感器头c12对工件c50的3个位置(可以多个位置)进行测高(高度数据H1’、H2’、H3’...),并对载物治具c40与工件c50测试点位置相近的点也进行测高(高度数据h1’、h2’、h3’...),对于测试点就产生了工件额高度:(△h1’、△h2’、△h3’...)。
通常,热压装置还包括与第一检测部c100和第二检测部c101电性连接的处理器,处理器根据第一组检测数据和第二组检测数据,判定加热保压部c20对工件c50进行加热保压的工艺是否符合要求。
一般来讲,第二组检测数据和第一组检测数据的检测位置相同,这样,可以根据第一组检测数据和第二组检测数据的对比,判定加热保压的工艺是否符合要求。
比如,在加热保压后,工件额高度的变化率要低于预定阈值,根据第二组检测数据和第一组检测数据进行计算,得到的变化率低于预定阈值,则表明加热保压的工艺符合要求;否则,则判定加热保压的工艺不符合要求。
这里的变化率在一种可能的实现中,可以计算第二组检测数据与第一组检测数据之间的差值,将该差值的绝对值除以第一组检测数据,得到变化率。
在实际生产中,当检测出工件c50的外观不合格时,通常需要剔除这些不合格的工件c50,因此,本公开提供的检测部还可以包括移送装置和回收料盒,AOI相机C13在检测到工件c50的外观不合格时,移送装置将工件c50和/或载物治具c40搬运至回收料盒。
综上所述,本公开提供的热压装置,通过在加热保压的工序前后增加对工件额高度以及工件的外观AIO检测,增加了对加热保压效果的判定因素,提高了工件封装的优良率。
其中,在加热保压工序之前增加工件的外观检测,便于直接剔除不良工件,仅对合格的工件进行加热保压,进而避免了对不良工件的加热保压,提高了工件封装的优良率;在加热保压工序之后增加工件的外观检测,便于剔除加热保压后产生质量问题的不良工件,避免了将加热保压后的不良工件流入到后续的封装工序中,也进一步提高了工件封装的优良率;在加热保压工序之前和加热保压工序之后均增加工件的外观检测以及工件额高度检测,从而可以根据工件在加热保压前后的检测数据,分析加热保压工序是否符合要求,进而可以优化加热保压工序中的相应工序、结构或参数。
图34是本公开一个实施例中提供的压力加载装置的结构示意图,图35是本公开一个实施例中提供的压力加载装置的剖视图,结合图34和图35,本公开提供的压力加载装置d1可以包括施压装置底板d11、低摩擦气缸d12、直线轴承d13、压力导向杆d14、隔热工件压板d15、温度传感器头d16和工件压板防转板d17,各部件的安装关系如下:
低摩擦气缸d12的推杆与压力导向杆d14的第一端连接。一般来讲,在对工件进行施压时的施压方向向下,因此低摩擦气缸d12的推杆通常竖向设置,即低摩擦气缸d12位于压力导向杆d14的上方,且低摩擦气缸d12的推杆与压力导向杆d14的第一端连接。
压力导向杆d14安装于施压装置底板d11内且压力导向杆d14的第二端安装有一个隔热工件压板d15,温度传感器安装于隔热工件压板d15的施压面,以便于对所施压的工件的温度进行实时测试。
直线轴承d13设置于施压装置底板d11内,压力导向杆d14容置于直线轴承d13内,直线轴承d13可以对压力导向杆d14进行支撑和导向。
工件压板防转板d17安装于施压装置底板d11的下方,隔热工件压板d15容置于工件压板防转板 d17的防转槽内。
在本公开的一种可能的实施例中,一个低摩擦气缸d12对应一个压力导向杆d14,一个压力导向杆d14下方对应安装一个隔热工件压板d15,每个隔热工件压板d15的施压面均安装一个温度传感器,一个隔热工件压板d15通常用于对一个工件进行施压。
为了保证低摩擦气缸d12的安装和固定,本公开提供的压力加载装置d1还可以包括气缸安装底板d18,低摩擦气缸d12安装于气缸安装底板d18上。
可选的,本公开提供的压力加载装置d1还可以包括连接柱d19,连接柱d19的两端分别安装于气缸安装底板d18和施压装置底板d11上。
为了防止隔热工件压板d15在对工件施压过程中转动,隔热工件压板d15可以为方形设计,工件压板防转板d17的防转槽与隔热工件压板d15的形状匹配。
在一种可能的实现方式中,请参见图36所示,其是本公开一个实施例中提供的气缸施压原理的气路控制示意图,本公开提供的压力加载装置d1还可以包括储气罐d110和气腔管道,储气罐d110通过气腔管道与低摩擦气缸d12的进气口连通。
储气罐d110可以增加回路中的气腔,减少气压变化影响气缸的输出压力值。
压力加载装置d1还可以包括电气控制单元和电气比例阀d111,电气控制单元与电气比例阀d111电性连接,电气比例阀d111安装于气腔管道上,电气控制单元控制电气比例阀d111出口的气压压力值,电气比例阀d111出口的气压进入低摩擦气缸d12,使低摩擦气缸d12的推杆有压力施加。
在实际应用中,电气比例阀d111的压力值通常为设置的预定压力,预定压力根据压力导向杆d14、隔热工件压板d15和温度传感器头d16的总重量以及工件所被施压的压力值设定。
工件所需压力值为:压力导向杆d14、方形隔热工件压板d15、温度传感器头d16的总重量G加上气缸的推力。工件所需压力值F如下:
F=G+Pa*S
其中,F为向工件施压的压力,Pa为电气比例阀d111设定的压力值,S为低摩擦气缸d12的缸径面积。
由上述公式可知,需要调整F的值,只要调整电气比例阀d111设定的压力值来改变。
综上所述,本公开提供的压力加载装置,通过在压力加载装置中设置低摩擦气缸,通过低摩擦气缸的推力实现对工件的施压,解决了在利用砝码对工件施压时的局限,减轻了压力加载装置的重量;通过设置温度传感器头可以对施压的工件的温度进行实时测量,可以随时掌控在施压过程中工件的温度变化。
另外,通过设置电气比例阀,可以根据压力导向杆、所述隔热工件压板和所述温度传感器头的总重量以及所述工件所被施压的压力值来设定电气比例阀的压力,使得电气比例阀出口的气压压力值施加于低摩擦气缸上压力可控,进而可以减少因施压压力过大或过小产生的不良品。
图37是本公开一个实施例中提供的工件施压设备的结构示意图,图38是本公开一个实施例中提供的工件施压设备的剖视图,结合图37和图38,本公开提供的工件施压设备可以包括加热顶升组件d2、工件治具组件d3和压力加载装置d1,这里所讲的压力加载装置d1可以参见图34和图35所示,这里就不再赘述。需要说明的是此处的工件施压设备即是加热保压部c20的其中一种结构。
工件治具组件d3位于加热顶升组件d2的上方,用于承载待施压的工件。
压力加载装置d1与加热顶升组件d2的顶升端相对设置,用于对工件治具组件d3所承载的工件进行施压。
输送机构将工件治具组件d3输送至加热顶升组件d2的上方时,加热顶升组件d2对工件治具组件d3内的工件进行加热,且将工件治具组件d3顶升至压力加载装置d1的下压面,压力加载装置d1中的低摩擦气缸d12推动压力导向杆d14对工件进行施压,压力加载装置d1中的温度传感器头d16对工件上的温度进行感知。
由于加热顶升组件d2对工件有加热作用,因此,本公开提供的工件施压设备还可以包括控制单元,温度传感器头d16与控制单元电性连接,温度传感器头d16检测到工件的温度未处于预定温度范围内时,即对工件的加热温度不合适时,可以利用控制单元调整加热顶升组件d2的加温值,从而更好的监控生产过程。
可选的,压力加载装置d1中的电气控制单元控制电气比例阀d111出口的气压压力值,使低摩擦气缸d12在恒定的压力值下推动压力导向杆d14对工件进行施压。在整个施压过程中,电气比例阀d111设定的压力保持不变,工件的压力值也会保持不变。
在实际应用中,输送机构将工件治具组件d3输送至加热顶升组件d2的上方时,加热顶升组件d2对工件治具组件d3内的工件进行加热,加热顶升组件d2将工件治具组件d3顶升,使工件接触压力加载装置d1的隔热工件压板d15,再继续顶起预定距离以使隔热工件压板d15推动压力导向杆d14来压缩低摩擦气缸d12的推杆,使低摩擦气缸d12的压力施加于工件。
综上所述,本公开提供的工件施压设备,通过在压力加载装置中设置低摩擦气缸,通过低摩擦气缸的推力实现对工件的施压,解决了在利用砝码对工件施压时的局限,减轻了压力加载装置的重量;通过设置温度传感器头可以对施压的工件的温度进行实时测量,可以随时掌控在施压过程中工件的温度变化。
另外,通过设置电气比例阀,可以根据压力导向杆、所述隔热工件压板和所述温度传感器头的总重量以及所述工件所被施压的压力值来设定电气比例阀的压力,使得电气比例阀出口的气压压力值施加于低摩擦气缸上压力可控,进而可以减少因施压压力过大或过小产生的不良品。
