Description

一种用于CNC生产线的砂纸自动替换装置 技术领域
本发明涉及CNC生产线领域，特别涉及一种用于CNC生产线的砂纸自动替换装置。
背景技术
在CNC生产线中，通常设有CNC打磨机床，对最后加工成型的零部件或结构件进行抛光打磨，使其符合设计的表面光洁度要求，而在现有的CNC打磨机床上，砂纸的剥离及替换较为繁琐，自动化程度低，需要人工辅助的步骤较多，剥离及替换效率低下，且容易出现剥离不净、剥离残留、砂纸替换效率低下、且出现供给设备由于砂纸卡住导致的频繁宕机等问题。有鉴于此，实有必要开发一种用于CNC生产线的砂纸自动剥离机构，用以解决上述问题。
发明内容
针对现有技术中存在的不足之处，本发明的目的是提供一种用于CNC生产线的砂纸自动替换装置，在提高剥离效率的同时，还能够有效解决剥离不净、剥离残留等问题，节省了成本，同时还解决了砂纸供给过程中出现的砂纸卡机等问题，提高了砂纸替换效率及成功率，进而提高了生产率。
为了实现根据本发明的上述目的和其他优点，提供了一种用于CNC生产线的砂纸自动替换装置，包括：
砂纸自动供给机构，该砂纸自动攻击机构包括支架组件、及设于支架组件上的砂纸收纳组件与砂纸取出板；以及
与支架组件相对接的砂纸自动剥离机构，该砂纸自动剥离机构包括安装板、及安装在安装板上的剥离驱动组件与剥离组件，
其中，剥离组件与剥离驱动组件传动连接，剥离组件在剥离驱动组件的驱动下周期性地将打磨头上的废旧砂纸剥离，砂纸取出板周期性地向被剥离 砂纸后的打磨头供给新砂纸。
优选的是，支架组件包括基板及取砂驱动部，砂纸收纳组件及砂纸取出板设于基板上。
优选的是，砂纸收纳组件包括砂纸收纳筒及砂纸压块，砂纸取出板与基板滑动连接，砂纸收纳筒内形成有贯穿其上下的第一贯穿孔从而使得砂纸收纳筒的上端及下端均敞开。
优选的是，砂纸收纳筒的底部形成有贯穿其左右的第二贯穿孔从而使得砂纸收纳筒的底部形成有左贯穿口及右贯穿口，砂纸压块可滑动地设于第一贯穿孔内，砂纸取出板从第二贯穿孔中穿过，砂纸取出板可在取砂驱动部的驱动下沿基板往复滑移。
优选的是，安装板与支架组件相对接且沿竖直方向延伸，剥离组件包括剥离安装板及固定安装于剥离安装板上的剥离板，其中，剥离安装板沿竖直方向延伸，剥离安装板与剥离驱动组件传动连接，剥离板可随剥离安装板在剥离驱动组件的驱动下在竖直平面内往复升降。
优选的是，剥离安装板上固定安装有贴合板，贴合板位于玻璃板的正下方。
优选的是，剥离板与贴合板位于同一竖直平面内且两者间隔设置以形成位于两者之间的砂纸收集空间。
优选的是，剥离板的下沿处设有沿玻璃板内侧斜向上延伸的剥离引导斜面，剥离引导斜面与竖直平面间的夹角为θ，则有3°≤θ≤8°。
优选的是，贴合板的上沿处一体式地形成有横截面呈山形结构的砂纸引导结构，该砂纸引导结构包括：
在贴合板外侧斜向上延伸的第一引导斜面，该第一引导斜面往贴合板的内侧倾斜；以及
在贴合板内侧斜向上延伸的第二引导斜面，该第二引导斜面往贴合板的外侧倾斜，
其中，第一引导斜面与竖直平面间的夹角为α，第二引导斜面与竖直平面间的夹角为β，则有15°≤α≤30°，5°≤β≤15°。
优选的是，砂纸取出板的上表面开设有砂纸取出槽，该砂纸取出槽位于 砂纸取出板的其中一端，在砂纸取出板沿基板往复滑移的过程中，砂纸取出槽选择性地与第一贯穿孔相对接。
本发明与现有技术相比，其有益效果是：
1、由于剥离组件与剥离驱动组传动连接，剥离组件在剥离驱动组件的驱动下周期性地将打磨头上的废旧砂纸剥离，砂纸取出板周期性地向被剥离砂纸后的打磨头供给新砂纸，使得砂纸的剥离与替换一气呵成，省去了中间步骤，提高了砂纸剥离与替换的效率，进而提高了生产效率；
2、由于砂纸压块可滑动地设于第一贯穿孔内，砂纸取出板从第二贯穿孔中穿过，砂纸取出板可在取砂驱动部的驱动下沿基板往复滑移，从而使得砂纸取出板可以从砂纸收纳筒周期性地将砂纸取出；
3、由于砂纸取出板的上表面开设有砂纸取出槽，砂纸取出槽选择性地与第一贯穿孔相对接，从而使得砂纸可以周期性地落入砂纸取出槽中并随砂纸取出槽一同移动到砂纸贴附工位处；
4、由于剥离安装板可在剥离驱动组件的驱动下在竖直平面内往复升降，从而使得剥离板可以周期性地将废旧、破损的砂纸从打磨头上剥离；
5、由于砂纸打磨之后很多会出现翘曲或破损，贴合板能够向打磨头施加一定的压力，使得打磨头上的砂纸被压合平整以便于剥离板能够方便、快捷地侵入砂纸层，从而提高砂纸剥离的成功率；
6、由于剥离板的下沿处设有沿玻璃板内侧斜向上延伸的剥离引导斜面，该剥离引导斜面能够使得剥离后的废砂纸斜向上的被引导至位于剥离安装板与安装板之间的砂纸下落通道内，提高废砂纸的排出效率；
7、砂纸引导结构一方面能够防止贴合板将砂纸上沿压合过紧导致的剥离板不易介入，另一方面能够防止废砂纸碎屑在贴合板的顶部残留，便于废砂纸的有效排出。

具体实施方式
下面结合附图对本发明做进一步的详细说明，本发明的前述和其它目的、特征、方面和优点将变得更加明显，以令本领域技术人员参照说明书文字能够据以实施。在附图中，为清晰起见，可对形状和尺寸进行放大，并将在所有图中使用相同的附图标记来指示相同或相似的部件。在下列描述中，诸如中心、厚度、高度、长度、前部、背部、后部、左边、右边、顶部、底部、上部、下部等用词为基于附图所示的方位或位置关系。特别地，“高度”相当于从顶部到底部的尺寸，“宽度”相当于从左边到右边的尺寸，“深度”相当于从前到后的尺寸。这些相对术语是为了说明方便起见并且通常并不旨在需要具体取向。涉及附接、联接等的术语(例如，“连接”和“附接”)是指这些结构通过中间结构彼此直接或间接固定或附接的关系、以及可动或刚性附接或关系，除非以其他方式明确地说明。
参照图1，用于CNC生产线的砂纸自动替换装置包括：砂纸自动供给机构1与砂纸自动剥离机构2，其中，该砂纸自动攻击机构1包括支架组件11、及设于支架组件11上的砂纸收纳组件13与砂纸取出板113，砂纸自动剥离机构2与支架组件11相对接，该砂纸自动剥离机构2包括安装板21、及安装在安装板21上的剥离驱动组件22与剥离组件23，剥离组件23与剥离驱动组件22传动连接，剥离组件23在剥离驱动组件22的驱动下周期性地将打磨头上的废旧砂纸剥离，砂纸取出板113周期性地向被剥离砂纸后的打磨头供给新砂纸。采用这种结构设计使得砂纸的剥离与替换一气呵成，省去了中间步骤，提高了砂纸剥离与替换的效率，进而提高了生产效率
参照图2及图3，砂纸自动供给机构1包括：支架组件11以及砂纸收纳组件13，其中，该支架组件11包括基板112及取砂驱动部115，砂纸收纳组件13设于基板112上，除此之外，基板112上还设有砂纸取出板113，砂纸收纳组件13包括砂纸收纳筒131及砂纸压块132，砂纸取出板113与基板112滑动连接，砂纸收纳筒131内形成有贯穿其上下的第一贯穿孔134从而使得砂纸收纳筒131的上端及下端均敞开，砂纸收纳筒131的底部形成有贯穿其左右的第二贯穿孔135从而使得砂纸收纳筒131的底部形成有左贯穿口及右 贯穿口，砂纸压块132可滑动地设于第一贯穿孔134内，砂纸取出板113从第二贯穿孔135中穿过，砂纸取出板113可在取砂驱动部115的驱动下沿基板112往复滑移，第二贯穿孔135的贯穿方向与砂纸取出板113的滑移方向相一致。通常可以在砂纸收纳筒131中放入层叠放置的砂纸组，由于砂纸的边缘有些许翘曲，砂纸压块132除了可以将砂纸压的平整外，还可以给砂纸组提供一个竖直向下的推力，使得最底部的砂纸被取走后，剩下的砂纸能够在其自身重力及推力的作用下向下行进一定距离，为下一次砂纸取料做好准备，使得砂纸取出板可以从砂纸收纳筒中周期性且不间断地将砂纸取出。在一实施方式中，砂纸压块132的顶部连接有压块提手1321。在优选的实施方式中，砂纸收纳筒131的侧壁上开设有若干个用于观察砂纸收纳筒131内砂纸余量的观察窗口。
参照图2、图3及图10，第二贯穿孔135中、砂纸取出板113的上方设有砂纸导向板133，砂纸导向板133中设有砂纸导向通孔1331，该砂纸导向通孔1331的孔径尺寸与第一贯穿孔134的孔径尺寸相同，该砂纸导向通孔1331与第一贯穿孔134同心设置，从而使得砂纸收纳筒131中的砂纸经砂纸导向板133的导向后可以顺畅地被导入到砂纸取出板113上。
进一步地，砂纸取出板113的上表面开设有砂纸取出槽1131，该砂纸取出槽1131位于砂纸取出板113的其中一端，在砂纸取出板113沿基板112往复滑移的过程中，砂纸取出槽1131选择性地与第一贯穿孔134相对接。
参照图2～图6，基板112上、砂纸收纳组件13的旁侧设有砂纸隔断组件14，该砂纸隔断组件14包括：
隔断支架；
设于所述隔断支架上的隔断驱动器143；以及
设于所述隔断支架上的隔板145，
其中，隔板145可在隔断驱动器143驱动下选择性地插入砂纸导向板133与砂纸取出板113之间，从而使得当砂纸取出槽1131中导入有砂纸时，隔板145可以将砂纸取出槽1131中的砂纸与该砂纸之上的其余砂纸隔断开，防止砂纸取出槽1131中的砂纸与其余砂纸粘连，而当砂纸取出槽1131中需要导入砂纸时，隔板又可以从砂纸导向板133与砂纸取出板113之间抽离，使得 砂纸能够顺利导入到砂纸取出槽1131中。在一实施方式中，隔断支架包括左支架141及右支架142，左支架141与右支架142平行且间隔设置，左支架141与右支架142之间设有至少两根导柱144，隔断驱动器143滑动套设于导柱144之上。在优选的实施方式中，隔断支架、隔断驱动器143上罩设有可供隔板145进出的防护罩146。
进一步地，基板112上设有砂纸取出导轨114，砂纸取出板113与砂纸取出导轨114滑动配接。
进一步地，砂纸隔断组件14架设于砂纸取出导轨114之上且隔板145与砂纸取出导轨114相隔一定距离，从而可以节省空间，降低设备占地面积。
参照图6～图9，砂纸取出导轨114上沿其延伸方向依次设有砂纸贴附工位P1、以及砂纸隔断工位P2。砂纸取出槽1131在随砂纸取出板113的滑移过程中交替地从砂纸贴附工位P1运动到砂纸隔断工位P2，或者从砂纸隔断工位P2运动到砂纸贴附工位P1，从而当砂纸取出槽1131在砂纸隔断工位P2处取出砂纸后，移动到砂纸贴附工位P1处等待打磨头将砂纸贴附工位P1处上的砂纸取走。
进一步地，砂纸取出槽1131的深度大于单片砂纸的厚度且小于两片砂纸的厚度，由于砂纸的边缘有一定的翘曲度，隔板145能够方便地将砂纸取出槽1131中的砂纸与其他砂纸分隔开，从而进一步保证了单次只取出一片砂纸的成功率。
参照图9，取砂驱动部115包括：
设于基板112上的导向杆1152，其延伸方向与砂纸取出导轨114的延伸方向相一致；以及
滑动套设于导向杆1152上的第一驱动器1151，
其中，第一驱动器1151与砂纸取出板113传动连接，在优选的实施方式中，取砂驱动部115罩设有驱动部防护板111。
参照图3、图4、及图6，砂纸取出槽1131的底部开设有贯穿砂纸取出板113的通孔，基板112的下方、砂纸贴附工位P1处设有用于感应砂纸取出槽1131中是否有砂纸的砂纸检测传感器116，基板112的上方、砂纸贴附工位P1处设有位置传感器1121，且该位置传感器1121位于砂纸取出板113的 旁侧。
参照图2及图3，基板112上还设有打磨头定位组件12，该打磨头定位组件12包括：
设于基板112上的定位底板121；以及
设于定位底板121边缘处的第一定位块122、第二定位块123、及第三定位块124，
其中，第一定位块122、第二定位块123、及第三定位块124环绕构成位于第一定位块122与第二定位块123之间的第一定位通道125及位于第二定位块123与第三定位块124之间的第二定位通道126，第一定位通道125与第二定位通道126相互连通且垂直。由于打磨头与其驱动器的连接是偏心连接，经过第一定位通道125及第二定位通道126的定位之后，其在砂纸贴附工位P1处能够准确地将砂纸贴附于其上。
参照图12，通常，打磨机床上装有打磨头3，打磨头3连接有可更换的砂纸，在实际应用中，我司发现现有技术中砂纸与打磨头3的连接方式不能满足实际应用需求，往往在打磨过程中出现砂纸脱落、砂纸局部磨损严重等现象，为此我司发明了设置于打磨头3与砂纸之间砂纸贴附结构31，参照图16，该砂纸贴附结构31包括缓冲垫312，以及贴附与缓冲垫312其中一个侧面上的砂纸311，缓冲垫312的另一面贴附与打磨头3之上，其中，缓冲垫312与打磨头3及砂纸311间均采用魔术贴的贴附方式。更换了砂纸贴附结构后，由于魔术贴的贴附效果超群，在实际应用中又出现了砂纸311不易从缓冲垫312剥离及剥离不净的问题，为此我司发明了用于CNC生产线的砂纸自动剥离机构2，以用于解决上述问题。
参照图1及图11，砂纸自动剥离机构2包括：安装板21、剥离驱动组件22、及剥离组件23，其中，安装板21沿竖直方向延伸，剥离驱动组件22安装在安装板21上，剥离组件23与剥离驱动组件22传动连接，该剥离组件23包括剥离安装板231及固定安装于剥离安装板231上的剥离板232，剥离安装板231沿竖直方向延伸，剥离安装板231与剥离驱动组件22传动连接，剥离安装板231可在剥离驱动组件22的驱动下在竖直平面内往复升降。在一实施方式中，剥离驱动组件22包括剥离驱动气缸221及与剥离驱动气缸221 的动力输出端相固接的连接块222，剥离驱动气缸221带动连接块222在竖直平面内往复升降，连接块222与剥离安装板231的顶部相固接以使得剥离安装板231与安装板21平行且间隔设置，从而形成位于剥离安装板231与安装板21之间的砂纸下落通道，使得剥离后的废砂纸能够通过该砂纸下落通道毫无阻拦的下落以便于后续对废砂纸的收集。在优选的实施方式中，安装板21上设有左限位块211及右限位块212，左限位块211及右限位块212位于剥离安装板231的最高位置处。通常在剥离组件23及剥离驱动组件22上往往罩设有剥离机构保护罩25。
再次参照图11，剥离安装板231上固定安装有贴合板233，贴合板233位于玻璃板232的正下方，由于砂纸打磨之后或多或少会出现翘曲或破损，贴合板233能够向砂纸施加一定的压力，使得砂纸恢复平整以便于剥离板232能够方便、快捷地侵入砂纸层，从而提高砂纸剥离的成功率。
进一步地，剥离板232与贴合板233位于同一竖直平面内且两者间隔设置以形成位于两者之间的砂纸收集空间。在优选的实施方式中，剥离安装板231呈倒置的U字形结构，剥离安装板231包括与连接块222相固接的顶板以及分别固接于所述顶板两端的左悬臂与右悬臂，左悬臂与右悬臂相互平行且间隔设置以形成位于两者之间的让位空间，剥离板232及贴合板233均安装于所述左悬臂与右悬臂之间，该砂纸收集空间能够收剥离后的废砂纸能够及时、有效地被引导至位于剥离安装板231与安装板21之间的砂纸下落通道内，便于剥离后的废砂纸及时被排出，防止废砂纸对后续的剥离作用产生干扰。
进一步地，剥离板232与贴合板233间的间距为8mm～15mm。在一实施方式中，剥离板232与贴合板233间的间距为8mm。在另一实施方式中，剥离板232与贴合板233间的间距为10mm。在又一实施方式中，剥离板232与贴合板233间的间距为15mm。
参照图13及图14中的局部放大处，剥离板232的下沿处设有沿玻璃板232内侧斜向上延伸的剥离引导斜面2321，剥离引导斜面2321与竖直平面间的夹角为θ，则有3°≤θ≤8°。剥离引导斜面2321能够使得剥离后的废砂纸斜向上的被引导至位于剥离安装板231与安装板21之间的砂纸下落通道内，提 高废砂纸的排出效率。在一实施方式中，θ＝5°。在优选的实施方式中，所述砂纸下落通道内还设有固接于剥离安装板231内侧的砂纸刮板235，砂纸刮板235的末端与安装板21的侧壁相抵，从而在砂纸剥离过程中，砂纸刮板235能够将剥离下的废砂纸及时向下刮走，防止废砂纸过多对所述砂纸下落通道造成堵塞。
进一步地，贴合板233的上沿处一体式地形成有横截面呈山形结构的砂纸引导结构，该砂纸引导结构包括：
在贴合板233外侧斜向上延伸的第一引导斜面2331，该第一引导斜面2331往贴合板233的内侧倾斜；以及
在贴合板233内侧斜向上延伸的第二引导斜面2332，该第二引导斜面2332往贴合板233的外侧倾斜，
其中，第一引导斜面2331与竖直平面间的夹角为α，第二引导斜面2332与竖直平面间的夹角为β，则有15°≤α≤30°，5°≤β≤15°。该砂纸引导结构一方面能够防止贴合板233将砂纸上沿压合过紧导致的剥离板232不易介入，另一方面能够防止废砂纸碎屑在贴合板233的顶部残留，便于废砂纸的有效排出。
参照图11～图15，剥离板232的下沿处设有若干个剥离齿234。
进一步地，剥离齿234沿竖直方向延伸，相邻剥离齿234间平行且间隔设置，采用这种结构能够使得多个剥离齿234形成爪形结构，能够更快、更顺畅的介入砂纸层，从而提高砂纸的剥离效率。
参照图11，剥离安装板231上固定安装有支架213，支架213上设有打磨头定位板214，其中，打磨头定位板214上开设有至少一个打磨头容纳槽2141，支架213与剥离安装板231间形成有允许剥离安装板231及剥离板232通过的剥离通道。
进一步地，安装板21的正下方对接有具有一定容纳空间的废砂纸收纳箱24，该废砂纸收纳箱24在其顶部敞开，废砂纸收纳箱24位于所述剥离通道的正下方，参照图5，剥离后的废砂纸能够通过废砂纸收纳箱24的顶部敞口直接下落至废砂纸收纳箱24内，从而被快速、有效地收集，不会对生产车间及机台造成污染，具有较高的实用价值。
工作原理：首先，砂纸取出板113及隔板145位于如图6～图8所示的状态，此时，砂纸取出槽1131位于砂纸隔断工位P2处，待一片砂纸从砂纸收纳筒131中下落到砂纸取出槽1131中时，隔板145插入砂纸导向板133与砂纸取出板113之间，使得砂纸取出槽1131中的砂纸与其余砂纸分割开并使得其余砂纸不再下落，砂纸取出板113往砂纸贴附工位P1处运动直至砂纸取出槽1131运动到砂纸贴附工位P1处，打磨过后的打磨头经砂纸自动剥离机构2将其上的废旧砂纸剥离，然后经过打磨头定位组件12进行定位，机械手将打磨头夹持只砂纸贴附工位P1处并将砂纸取出槽1131上的砂纸贴附于其上，隔板145在砂纸隔断工位P2处使得砂纸收纳筒131中的砂纸不再下落直至砂纸取出槽1131再次回到砂纸贴附工位P1处；如此往复循环，直至砂纸收纳筒131中的砂纸被全部取出；当砂纸收纳筒131中的砂纸被全部取出后，可按需将下一组砂纸组装入砂纸收纳筒131中。
这里说明的设备数量和处理规模是用来简化本发明的说明的。对本发明的应用、修改和变化对本领域的技术人员来说是显而易见的。
尽管本发明的实施方案已公开如上，但其并不仅限于说明书和实施方式中所列运用，它完全可以被适用于各种适合本发明的领域，对于熟悉本领域的人员而言，可容易地实现另外的修改，因此在不背离权利要求及等同范围所限定的一般概念下，本发明并不限于特定的细节和这里示出与描述的图例。
