Description
本發明係提供一種真空吸盤,尤指使用以真空吸引預設物件之吸盤,其於座體下方底座之入氣通道設有往復位移之加壓閥片,藉由加壓閥片中央穿孔來縮小面積以增大真空吸力及減少因未能吸附到預設物件時的真空損失。 The invention provides a vacuum suction cup, in particular to a suction cup which is used for vacuum attracting a preset object, and the inlet passage of the base below the seat body is provided with a reciprocating displacement pressure valve piece, which is reduced by the central perforation of the pressure valve piece. Area to increase vacuum suction and reduce vacuum loss due to failure to adsorb to preset objects.
按,在現今產業的加工或運送上越來越頻繁的運用真空吸盤,真空吸盤的技術主要可分為兩種,一種為接觸式真空吸盤,另一種為非接觸式真空吸盤,普遍而言,較為常見且應用層面較廣泛的為接觸式真空吸盤技術。 According to the vacuum suction cup, the vacuum suction cup technology is mainly used in the processing or transportation of the current industry. The vacuum suction cup technology can be mainly divided into two types, one is a contact vacuum suction cup, and the other is a non-contact vacuum suction cup. Generally speaking, relatively Common and applicable applications are contact vacuum chuck technology.
以接觸式真空吸盤而言,其原理係直接在吸盤進氣口處直接施加負壓,在吸盤出氣口產生吸力以達到吸附工件之作用,但吸盤的吸附面必須覆蓋在實體範圍內否則將導致真空流失無法吸取工件。 In the case of a contact vacuum chuck, the principle is to directly apply a negative pressure directly at the suction port of the suction cup, and generate suction at the air outlet of the suction cup to achieve the function of adsorbing the workpiece, but the adsorption surface of the suction cup must be covered in the physical range or it will cause Vacuum loss cannot pick up the workpiece.
再者,吸盤的固定方式一般是以吸盤的吸附面大小為基礎而製作一個固定框架,其吸盤的數量有限,且無法隨機自動調整,須以人工調整,徒增操作上的不方便性。 Furthermore, the fixing method of the suction cup is generally based on the size of the suction surface of the suction cup to make a fixed frame. The number of suction cups is limited, and it cannot be automatically and randomly adjusted, and must be manually adjusted to increase the inconvenience in operation.
以非接觸式吸盤而言,其吸附工件時吸附面與工件表面仍有一段微小的距離,所以無法將工件緊密吸住,當吸盤高速移動或旋轉時 會因加速度而產生的慣性力將工件甩出,且非接觸式吸盤之吸附面一般以硬性的材料製作,如工程塑膠或鋁合金,又因其與吸附工件存在一段距離,為了加強吸力而無法設置一個較柔軟的緩衝墊,倘若吸盤的吸附面與工件接觸時容易造成工件的刮傷。 In the case of a non-contact type suction cup, the suction surface is still slightly spaced from the surface of the workpiece when the workpiece is sucked, so that the workpiece cannot be closely sucked, when the suction cup moves or rotates at a high speed. The inertial force generated by the acceleration will pull out the workpiece, and the suction surface of the non-contact suction cup is generally made of a hard material, such as engineering plastic or aluminum alloy, and because it has a distance from the adsorption workpiece, in order to enhance the suction force, Set a softer cushion, which will cause scratches on the workpiece if the suction surface of the suction cup contacts the workpiece.
上述習用之兩種真空吸盤,仍存在缺失有待改善,所以如何解決上述問題讓接觸式真空吸盤應用層面較廣泛,此即為本發明人與從事此行業者所亟欲改善之目標所在。 There are still some shortcomings in the above-mentioned vacuum suction cups to be improved, so how to solve the above problems makes the contact vacuum suction cups have a wider application level, which is the goal that the inventors and those engaged in the industry desire to improve.
故,發明人有鑑於上述缺失,乃蒐集相關資料,經由多方評估及考量,並以從事於此行業累積之多年經驗,經由不斷試作及修改,始設計出此種真空吸盤的發明專利者。 Therefore, in view of the above-mentioned shortcomings, the inventors have collected relevant materials, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, the invention patents of such vacuum chucks were designed.
本發明之主要目的乃在於該真空吸盤使用時,加壓閥片便會受到空氣推動而位移,則入氣通道連通處便會縮小到僅剩加壓閥片中央穿孔的面積,藉此讓氣流穿透處之面積縮小,以增大真空吸力,便可讓預設物件被真空吸盤穩固吸引,高速移動時預設物件也不會甩落。 The main purpose of the present invention is that when the vacuum chuck is used, the pressurized valve piece is displaced by the air, and the inlet passage portion is reduced to the area where only the central portion of the pressure valve plate is perforated, thereby allowing the air flow. The area of the penetration is reduced to increase the vacuum suction, so that the preset object is stably attracted by the vacuum suction cup, and the preset object does not fall when moving at high speed.
本發明之次要目的乃在於,利用加壓閥片抵持於升降空間與銜接通道之間的止擋面,讓升降空間與銜接通道之間的連通處縮小到僅剩加壓閥片之穿孔,便可減少進入氣槽之空氣,當真空吸盤吸引具多個鏤空處或呈不規則狀之預設物件時,真空吸引裝置排除空氣的速度為大於空氣經過穿孔進入氣槽的速度,所以氣槽之真空度就可減少損失,進而可讓真空吸盤增大使用範疇,及提升真空吸引之穩定性。 A secondary object of the present invention is to use a pressure valve plate to abut against a stop surface between the lifting space and the connecting passage, so that the communication between the lifting space and the connecting passage is reduced to the perforation of only the pressurized valve plate. The air entering the air trough can be reduced. When the vacuum suction cup attracts a plurality of hollow places or irregular shaped objects, the speed of the vacuum suction device excluding air is greater than the speed at which the air passes through the perforations into the air trough, so the gas The vacuum of the groove reduces the loss, which in turn increases the vacuum suction cup and improves the stability of the vacuum suction.
本發明之另一目的乃在於該底座底面設置接觸軟墊,接觸 軟墊為利用橡膠或矽膠等軟性發泡材質所製成,作為底座及預設物件之間的隔離,以防止兩者之間因摩擦而造成刮傷,且其各吸引孔道之間均不連通,使得各吸引孔道形成獨立吸盤之效果,又可避免產生破真空之情況,進而可提升加工或運輸之穩定性。 Another object of the present invention is to provide a contact pad on the bottom surface of the base to contact The cushion is made of a soft foaming material such as rubber or silicone rubber, and is used as a separation between the base and the preset object to prevent scratching due to friction between the two, and the suction holes are not connected to each other. Therefore, each attracting channel forms the effect of independent suction cup, and can avoid the situation of vacuum breaking, thereby improving the stability of processing or transportation.
本發明之又一目的乃在於該底座之入氣通道內裝設有濾網來濾除微小異物,以避免異物進入升降空間、銜接通道或氣槽產生阻塞,且座體頂面具有清潔槽口及其鎖固之清潔螺絲,可拆除清潔螺絲並由清潔槽口施以正壓吹氣,便可將阻塞之異物吹出真空吸盤,進而達到提升使用之穩定性、減少維修次數及快速排除阻塞之效果。 Another object of the present invention is to provide a filter screen in the air inlet passage of the base to filter out minute foreign matter, so as to prevent foreign matter from entering the lifting space, the connecting passage or the air groove to block, and the top surface of the seat body has a cleaning slot and The locking screw can be removed, and the cleaning screw can be removed and the positive air blow is applied by the cleaning slot, so that the blocked foreign matter can be blown out of the vacuum suction cup, thereby improving the stability of use, reducing the number of maintenance and quickly eliminating the blocking effect. .
本發明之再一目的乃在於該座體頂面具有固定部及其周圍設有至少四個固定孔,讓預設載具可對正真空吸盤的中心並形成穩固定位,進而達到精準定位之目的。 A further object of the present invention is to provide at least four fixing holes on the top surface of the base body and the periphery thereof, so that the preset carrier can be aligned with the center of the vacuum chuck and form a stable fixed position, thereby achieving accurate positioning. .

The inner side of the stopping surface 213 is further provided with an engaging passage 214 connected to the air groove 10, and is inflated. The channel 21 is provided with a filter 22 having an outer diameter larger than the inner diameter of the lifting space 212 and abutting against the step 211. The outer space of the lifting space 212 is smaller than the inner diameter of the lifting space 212 and larger than the inner diameter of the connecting channel 214.

該接觸軟墊3為對應設置於底座2底面,且接觸軟墊3下方具有接觸預設物件4之吸附底面31,吸附底面31則朝上貫穿設有對 正連通各入氣通道21之複數吸引孔道32。 The contact pad 3 is correspondingly disposed on the bottom surface of the base 2, and has an adsorption bottom surface 31 contacting the preset object 4 under the contact pad 3, and the adsorption bottom surface 31 is provided with the pair facing upward. The plurality of suction holes 32 that are connected to the respective intake passages 21 are being communicated.
上述之底座2對正座體1氣槽10以外處設有複數固定元件25,藉此將底座2以鎖固到座體1,且底座2於複數入氣通道21外側接觸座體1之壁面處設有密封墊圈26,利用座體1或底座2凹設有凹槽容納並擠壓密封墊圈26形成密閉狀態,亦可於座體1與真空吸引裝置12連接處設置密封墊圈26,然而有關固定及密封之技術係為習知之技術,且該細部構成非本案發明要點,茲不再贅述。 The base 2 is provided with a plurality of fixing elements 25 at the outer side of the air box 10 of the right seat body 1 , whereby the base 2 is locked to the seat body 1 , and the base 2 contacts the wall surface of the seat body 1 outside the plurality of air inlet passages 21 . A sealing gasket 26 is provided. The seat body 1 or the base 2 is recessed with a recess to receive and press the sealing gasket 26 to form a sealed state. The sealing gasket 26 can also be disposed at the joint of the seat body 1 and the vacuum suction device 12, but the fixing is fixed. And the technology of sealing is a well-known technique, and this detail constitutes a non-inventive point of the invention, and will not be described again.
請參閱第一、二、三、四、五、六、七圖所示,由圖中可以清楚看出,該真空吸盤未使用(真空吸引裝置12未啟動)時,加壓閥片23為下落抵靠於濾網22上表面,此時空氣可經由加壓閥片23外周緣與升降空間212內壁面之間的間隙連通流動,該真空吸盤使用時,為先將接觸軟墊3抵持於預設物件4之上表面,再啟動真空吸引裝置12將氣槽10內之空氣排到外部,此時,入氣通道21、升降空間212及銜接通道214之空氣為朝氣槽10移動,則加壓閥片23便會受到空氣之推動,由抵靠於濾網22上表面朝上位移至抵持於止擋面213,則升降空間212與銜接通道214之間的連通處便會縮小到僅剩加壓閥片23中央穿孔231的面積,此時,座體1之氣槽10內部空氣排出後為呈真空狀態,而僅有加壓閥片23之穿孔231為穿透處,藉此讓氣流穿透處之面積縮小,以增大真空吸力,便可讓預設物件4被真空吸盤穩固吸引,高速移動時預設物件4也不會甩落。 Please refer to the first, second, third, fourth, fifth, sixth and seventh figures. It can be clearly seen from the figure that when the vacuum chuck is not used (the vacuum suction device 12 is not activated), the pressure valve piece 23 is dropped. Abutting against the upper surface of the filter screen 22, the air can flow through the gap between the outer peripheral edge of the pressure valve plate 23 and the inner wall surface of the lifting space 212. When the vacuum chuck is used, the contact cushion 3 is firstly resisted. Presetting the upper surface of the object 4, the vacuum suction device 12 is further activated to discharge the air in the air tank 10 to the outside. At this time, the air of the air inlet passage 21, the lifting space 212 and the connecting passage 214 is moved toward the air tank 10, and then The pressure valve piece 23 is pushed by the air, and is displaced upward against the upper surface of the screen 22 to abut against the stop surface 213, so that the communication between the lifting space 212 and the connecting passage 214 is reduced to only The area of the central perforation 231 of the pressurized valve piece 23 is left. At this time, the air inside the air groove 10 of the seat body 1 is in a vacuum state, and only the through hole 231 of the pressure valve piece 23 is a penetration portion, thereby allowing The area of the airflow penetration is reduced to increase the vacuum suction, so that the preset object 4 is vacuumed. A firm base to attract, default object moving at high speed 4 will not be thrown off.
由於底座2之入氣通道21及接觸軟墊3之吸引孔道32為穿孔型式,而非一般橡膠吸盤之大面積接觸型式,所以在固定的底座2 面積下就可以增加吸引處數量,如圖示實施立為在底座2直徑141mm的圓形面上設置156個入氣通道21,相較於一般接觸式真空吸盤的4、8或16個吸盤,若要裝設相同於本發明數量的吸盤,其面積對比於本發明將需增加數十倍,是以,本發明在固定框架的面積下增加吸盤數量以提高吸附實體面積的機率,因此不受預設物件4的部分鏤空而影響吸附力,上述實施例之面積大小及孔道數量僅為舉例說明,非因此即侷限本發明之專利範圍。 Since the air inlet passage 21 of the base 2 and the suction passage 32 of the contact cushion 3 are of a perforated type, instead of the large-area contact type of the general rubber suction cup, the fixed base 2 is fixed. The number of suction points can be increased under the area. As shown in the figure, 156 air inlet passages 21 are provided on the circular surface of the base 2 with a diameter of 141 mm, compared with 4, 8 or 16 suction cups of the general contact vacuum suction cup. In order to install the same number of suction cups as the present invention, the area thereof needs to be increased by several tens of times compared with the present invention. Therefore, the present invention increases the number of suction cups under the area of the fixed frame to increase the probability of adsorbing the solid area, and thus is not The portion of the predetermined object 4 is hollowed out to affect the adsorption force. The area size and the number of holes in the above embodiment are merely illustrative and are not intended to limit the scope of the invention.
再者,當真空吸盤使用於吸引具多個鏤空處或呈不規則狀之預設物件4時(現今有很多精密物件為了縮小體積或與其他物件共同組合成一個產品,往往在精密物件本身會有大面積被挖空),接觸軟墊3之局部複數吸引孔道32為對正於鏤空處,此時吸引孔道32無法形成密閉,所以真空吸引裝置12啟動後,外部空氣會依序經過吸引孔道32、入氣通道21、升降空間212及銜接通道214後進入氣槽10,但因為升降空間212與銜接通道214之間的連通處縮小到僅剩加壓閥片23之穿孔231,便可減少進入氣槽10之空氣,且真空吸引裝置12排除空氣的速度為大於經過複數加壓閥片23之穿孔231進入氣槽10的速度,所以氣槽10之真空度就可減少損失,進而可讓真空吸盤增大使用範疇,及提升真空吸引之穩定性。 Furthermore, when the vacuum chuck is used to attract a predetermined object 4 having a plurality of hollows or irregular shapes (there are many precision objects in order to reduce the volume or combine with other objects into one product, often in the precision object itself. If a large area is hollowed out, the partial plurality of suction holes 32 contacting the cushion 3 are aligned with the hollow, and the suction hole 32 cannot be sealed at this time, so that after the vacuum suction device 12 is started, the external air passes through the suction hole sequentially. 32. The air inlet passage 21, the lifting space 212, and the connecting passage 214 enter the air tank 10, but since the communication between the lifting space 212 and the connecting passage 214 is reduced to only the through hole 231 of the pressing valve piece 23, the reduction can be reduced. The air entering the air tank 10, and the speed of the vacuum suction device 12 excluding the air is greater than the speed of entering the air tank 10 through the through holes 231 of the plurality of pressure valve sheets 23, so that the vacuum degree of the air tank 10 can reduce the loss, thereby allowing Vacuum chucks increase the range of use and enhance the stability of vacuum suction.
該接觸軟墊3為利用橡膠或矽膠等軟性發泡材質所製成,其各吸引孔道32之間均不連通,所以外部空氣僅能透過吸引孔道32進入座體1之氣槽10,不僅讓各吸引孔道32形成獨立吸盤之效果,又可減少因未吸附到實體物件時的真空流失之情況;另,因為是利用接觸軟墊 3作為底座2及預設物件4之間的隔離,接觸軟墊3底部之吸附底面31接觸預設物件4表面,由於接觸軟墊3為軟性發泡材質,便不會刮傷預設物件4表面,進而可讓加工或運輸之穩定性提升;此外,因為接觸軟墊3為軟性發泡材質,且真空吸盤所產生的吸力大,所以接觸軟墊3接觸預設物件4並進行真空吸引時,其接觸軟墊3可彈性變形,所以可讓接觸軟墊3確實的接觸預設物件4表面,即便預設物件4表面有不平整處,真空吸盤亦可確實的吸引住預設物件4,且真空吸盤不須調整位置就可吸引住預設物件4。 The contact pad 3 is made of a soft foaming material such as rubber or silicone rubber, and the suction holes 32 are not connected to each other. Therefore, the outside air can only enter the air groove 10 of the seat body 1 through the suction hole 32, not only Each of the suction channels 32 forms the effect of an independent suction cup, and reduces the loss of vacuum when the physical object is not adsorbed; and, because the contact cushion is utilized 3 As the isolation between the base 2 and the preset object 4, the suction bottom surface 31 of the bottom of the contact pad 3 contacts the surface of the preset object 4, and since the contact pad 3 is a soft foam material, the preset object 4 is not scratched. The surface, in turn, can improve the stability of processing or transportation; in addition, since the contact cushion 3 is a soft foaming material and the suction force generated by the vacuum chuck is large, the contact cushion 3 contacts the preset object 4 and is vacuum-attracted. The contact pad 3 is elastically deformable, so that the contact pad 3 can surely contact the surface of the preset object 4, and even if the surface of the preset object 4 is uneven, the vacuum cup can surely attract the preset object 4, And the vacuum chuck can attract the preset object 4 without adjusting the position.
該底座2之入氣通道21內裝設有濾網22,透過濾網22可濾除微小異物,以避免異物進入升降空間212、銜接通道214或氣槽10內產生阻塞之問題,進而可提升使用之穩定性並減少維修;此外,座體1頂面具有清潔槽口13及其鎖固之清潔螺絲131,當產生阻塞時,則可拆除清潔螺絲131,並由清潔槽口13朝氣槽10內施以正壓吹氣,便可將阻塞之異物吹出真空吸盤,由於排除動作簡單、方便,就可達到快速排除問題之目的。 The air inlet passage 21 of the base 2 is provided with a filter screen 22, and the filter net 22 can filter out minute foreign matter to prevent foreign matter from entering the lifting space 212, the connecting passage 214 or the air tank 10 to cause blockage, thereby improving The stability of the use is reduced and the maintenance is reduced; in addition, the top surface of the base body 1 has a cleaning notch 13 and a locking cleaning screw 131 thereof. When the blockage occurs, the cleaning screw 131 can be removed and the cleaning slot 13 faces the air groove 10 By applying a positive pressure blow, the blocked foreign matter can be blown out of the vacuum chuck, and the elimination action is simple and convenient, so that the problem of rapid elimination can be achieved.
該座體1頂面具有固定部14及其周圍設有至少四個固定孔15,預設載具(圖中未示出)為與固定部14組裝,再鎖固於至少四個固定孔15形成穩固定位,讓預設載具的中心可與真空吸盤的中心對正,進而達到精準定位之功能。 The top surface of the base body 1 has a fixing portion 14 and a periphery thereof, and at least four fixing holes 15 are provided. The preset carrier (not shown) is assembled with the fixing portion 14 and then locked to the at least four fixing holes 15 . Forming a stable fixed position allows the center of the preset carrier to be aligned with the center of the vacuum chuck to achieve precise positioning.
請參閱第一、二、三、四、五、六、七圖所示,由圖中可以清楚看出,該座體1所裝設真空吸引裝置12之實施例可為外接式之真空產生器或真空馬達,透過真空產生器或真空馬達直接將氣槽10內之空 氣抽出,便可具有真空吸引之效果,但由於真空產生器及真空馬達需額外設置且成本高昂,故,真空吸引裝置12之另一實施例則具有位於座體1氣槽10內之至少一個U型流道121,其U型流道121具有連通到氣槽10之複數通孔1210,且U型流道121二端分別連接於座體1之穿槽11及一般空壓機(圖中未示出),透過空壓機將空氣打入U型流道121,則利用白努利定理讓氣槽10中流速慢壓力大之空氣經由複數通孔1210進入U型流道121,便可讓氣槽10中的空氣排出而形成真空狀態,藉此讓廠商運用工廠內普遍具有的空壓機即可使用真空吸盤,廠商便不須另外購買真空產生器或真空馬達,進而可節省成本。 Please refer to the first, second, third, fourth, fifth, sixth and seventh figures. It can be clearly seen from the figure that the embodiment of the vacuum suction device 12 of the base 1 can be an external vacuum generator. Or vacuum motor, directly emptying the gas tank 10 through a vacuum generator or a vacuum motor The gas extraction can have the effect of vacuum suction, but since the vacuum generator and the vacuum motor need to be additionally arranged and costly, another embodiment of the vacuum suction device 12 has at least one of the air cells 10 in the seat body 1. The U-shaped flow channel 121 has a U-shaped flow channel 121 having a plurality of through holes 1210 connected to the gas groove 10, and the two ends of the U-shaped flow channel 121 are respectively connected to the through grooves 11 of the base body 1 and a general air compressor (in the figure) Not shown), the air is driven into the U-shaped flow passage 121 through the air compressor, and the air with a slow flow velocity in the air tank 10 is entered into the U-shaped flow passage 121 through the plurality of through holes 1210 by using the Bainuuli theorem. The air in the gas tank 10 is discharged to form a vacuum state, thereby allowing the manufacturer to use the vacuum chuck by using the air compressor generally available in the factory, so that the manufacturer does not need to purchase a vacuum generator or a vacuum motor, thereby saving costs.
再者,U型流道121為具有水平排列之至少一個漸擴流道1211,且漸擴流道1211二端分別設有對應連接各穿槽11之進氣流道1212及排氣流道1213,再於穿槽11裝設有伸出到座體1上方外部之對接組件122,進氣流道1212對應之對接組件122為連接於空壓機,讓空壓機之空氣先打入進氣流道1212,再經由漸擴流道1211及排氣流道1213後排出到外部,由於漸擴流道1211具有減速增壓的效果,便可將空氣確實的推動排出到外部。 Furthermore, the U-shaped flow passage 121 is at least one diverging flow passage 1211 having a horizontal arrangement, and the two ends of the diverging flow passage 1211 are respectively provided with an intake flow passage 1212 and an exhaust flow passage 1213 corresponding to the respective through grooves 11. The docking unit 11 is further provided with a docking component 122 extending to the outside of the seat body 1. The docking unit 122 corresponding to the air inlet runner 1212 is connected to the air compressor, so that the air of the air compressor is first driven into the air inlet. The flow path 1212 is further discharged to the outside through the diverging flow path 1211 and the exhaust flow path 1213. Since the diverging flow path 1211 has the effect of decelerating and supercharging, the air can be reliably pushed to the outside.
故,本發明為主要針對真空吸盤進行設計,而可於座體底部氣槽於複數穿槽處裝設真空吸引裝置,底座於底面凹設複數入氣通道,入氣通道內設有中央具穿孔之加壓閥片,使用時升降空間與銜接通道之間僅有穿孔連通以縮小面積來增大真空吸力及減少進入氣槽的空氣,且氣槽也不會破真空,以穩固吸引、高速移動時不會甩落及增大使用範疇為主要保護重點,惟,以上所述僅為本發明之較佳實施例而已,非因此即侷限本 發明之專利範圍,故舉凡運用本發明說明書及圖式內容所為之簡易修飾及等效結構變化,均應同理包含於本發明之專利範圍內,合予陳明。 Therefore, the present invention is mainly designed for a vacuum chuck, and a vacuum suction device can be installed at a plurality of slots in the bottom air groove of the base body, and the base is recessed with a plurality of air inlet passages on the bottom surface, and the center air passage is provided in the air inlet passage. The pressure valve piece has only perforation communication between the lifting space and the connecting passage to reduce the vacuum suction force and reduce the air entering the air groove, and the air groove does not break the vacuum, so as to stably attract and move at high speed. The scope of use will not be degraded and the scope of use will be the main protection focus.
