Description
本發明涉及利用負壓吸附物件的技術，特別有關一種異形薄片物件的負壓吸附器。 The present invention relates to the technology of using negative pressure to adsorb objects, and particularly relates to a negative pressure adsorber for special-shaped sheet objects.
在自動化作業中，常見使用負壓來吸持物件，以便對物件執行搬移、裝配、包裝等動作。 In automated operations, it is common to use negative pressure to hold objects in order to perform actions such as moving, assembling, and packaging the objects.
一般而言，負壓是經由空氣壓縮機等抽氣設備的驅動運作而形成，並且經由負壓管路導引至一個或多個負壓需求端，所述負壓需求端可以是一多軸機械臂的爪頭或是一工作站的桌面，在該爪頭或桌面上通常是憑藉至少一吸盤或一吸附器來對外生成負壓吸附力，用以吸附物件。其中，所述的吸附器常見是由具有多個負壓吸孔的盤狀元件所構成，或者是由一個或多個錐盆式吸盤組成。 Generally speaking, the negative pressure is formed by the driving operation of air extraction equipment such as an air compressor, and is guided to one or more negative pressure demand ends through a negative pressure pipeline, which may be a multi-axis The claw head of a robotic arm or the desktop of a workstation on which a negative pressure adsorption force is usually generated externally by means of at least one suction cup or an adsorber for adsorbing objects. The adsorber is usually composed of a disc-shaped element having a plurality of negative pressure suction holes, or is composed of one or more cone-shaped suction cups.
針對等待接受負壓吸持的物件而言，常見有形體輪廓為四邊形或矩形等較具規則的薄板物件(例如是玻璃板、膠板、PCB等)，還有形體中具有諸多細小彎摺輪廓(例如微米等級的彎曲輪廓)的異形薄片物件(例如是觸控螢幕的邊框遮板、金屬薄膜遮條或導電條、或膠貼用的薄膜等)。 For objects waiting to be held by negative pressure, the shape of the body is usually a regular thin plate such as a quadrangle or a rectangle (such as glass plate, rubber plate, PCB, etc.), and the body has many small curved outlines. (Such as curved contours in micron order) profiled sheet objects (such as bezels for touch screens, metal film masks or conductive strips, or films for adhesives, etc.).
在現有技術中，上述傳統的吸盤或吸附器可牢靠的被應用於吸附形體輪廓等較具規則的薄片物件(例如是玻璃板、膠板、PCB等)；但是，由於傳統錐盆式吸盤受到成型尺寸的限制(通常很難小於毫米)，且傳統吸附器上形成的負壓吸孔，受到傳統機械加工(例如鏜鑽或冲製)的限制，其多個負壓吸孔之間的孔隙最小值只能達到0.5mm，乃至於被用於吸附只具微米等級之細小彎摺 輪廓的異形薄片物件(例如是觸控螢幕的邊框遮板、金屬薄膜遮條或導電條、或膠貼用的薄膜、或複合於離形紙上的膠貼樣件等)時，尤其是當傳統吸盤或吸附器罩附於薄片物件之異形輪廓的邊緣時，所能產生的吸附效果並不理想。 In the prior art, the above-mentioned conventional suction cups or adsorbers can be reliably applied to more regular thin-sheet objects (such as glass plates, rubber sheets, PCBs, etc.), such as contours of suction shapes; Limitation of molding size (usually difficult to be less than millimeters), and the negative pressure suction holes formed on traditional adsorbers are limited by traditional machining (such as boring or punching), and the pores between multiple negative pressure suction holes The minimum value can only reach 0.5mm, and even it is used to adsorb fine bends with only micron level. Contoured shaped sheet objects (such as a touch screen frame shield, a metal film mask or a conductive strip, or a film for adhesive, or an adhesive sample compounded on release paper, etc.), especially when traditional When the suction cup or the adsorber cover is attached to the edge of the profiled profile of a thin object, the adsorption effect that can be produced is not ideal.
進一步的說，請參閱圖9，說明傳統吸盤或吸附器10應用在吸持異形薄片物件90時，吸盤或吸附器10上一部分的負壓吸孔11a能全部罩附到被吸持的異形薄片物件90並產生吸持力；但是，吸盤或吸附器10上另一部分的負壓吸孔11b只能有部分孔域罩附到異形薄片物件90；更細微的說，在異形薄片物件90之異形輪廓的邊緣，由於所述負壓吸孔11b只有部分孔域罩附到所述異形薄片物件90的輪廓邊緣，乃至於因負壓吸孔11b的部分孔域與大氣相通而形成〝破真空〞現象，造成異形薄片物件90的輪廓邊緣無法充分被吸附而發生軟垂現象，而且也影響整個吸盤或吸附器10的吸持力，這是傳統吸盤或吸附器10被應用於吸持異形薄片物件90時所易造成之吸力不足或易使異形薄片物件90受吸持後生成皺紋或變形而影響品質的主因。 Further, referring to FIG. 9, when a conventional suction cup or adsorber 10 is used to hold a shaped sheet object 90, a part of the negative pressure suction holes 11 a on the suction cup or the adsorber 10 can be completely covered to the held shaped sheet. The object 90 also generates a holding force; however, only a part of the hole cover of the negative pressure suction hole 11b on the suction cup or the adsorber 10 can be attached to the special-shaped sheet object 90; more specifically, the special-shaped sheet object 90 is shaped The edge of the contour, because only a part of the hole area of the negative pressure suction hole 11b is attached to the contour edge of the profiled sheet object 90, and even a part of the hole area of the negative pressure suction hole 11b communicates with the atmosphere to form a "broken vacuum". Phenomenon, causing the contoured edge of the shaped sheet object 90 to be unable to be fully absorbed and causing a soft droop phenomenon, and also affect the holding force of the entire suction cup or the adsorber 10, which is the traditional suction cup or the adsorber 10 is used to hold the shaped sheet object At 90 o'clock, the lack of suction is easy to cause the wrinkles or deformation of the shaped sheet object 90 after being held, which is the main reason for affecting the quality.
此外，受到傳統機械加工的拘束，負壓吸孔孔在吸附器10單位面積下分佈的數量難以提高，也是造成上述問題的因素之一。 In addition, due to the constraints of traditional machining, it is difficult to increase the number of negative pressure suction holes distributed per unit area of the adsorber 10, which is also one of the factors causing the above problems.
再者，由傳統應用於車輛進氣、排氣系統所常見的過濾器可知，該過濾器中的濾芯通常可見由高分子聚合物製成，且濾芯上分佈有諸多細小的通氣孔隙，且該等細小的通氣孔隙具備良好的通氣流暢性；但是，現階段技術中並沒有應用該高分子聚合物製成的濾芯技術，來改善上述吸附器10不易吸附異形薄片物件90的問題。 Furthermore, it is known from the filters that are traditionally applied to vehicle air intake and exhaust systems that the filter element in the filter is usually made of a high molecular polymer, and there are many fine ventilation pores distributed on the filter element. Such fine ventilation pores have good ventilation fluency; however, the filter element technology made of the polymer is not applied in the current stage of the technology to improve the problem that the adsorber 10 is not easy to adsorb the shaped sheet object 90.
有鑑於此，本發明旨在改善傳統負壓吸附器不利於吸持異形薄片物件的問題。 In view of this, the present invention aims to improve the problem that the conventional negative pressure adsorber is not conducive to holding the shaped sheet objects.

Wherein, at least one air chamber 21 is formed in the body 20, and at least one opening 22 communicating with the air chamber 21 is formed on the surface of the body 20. At least one inlet 23 communicating with the air chamber 21 is formed on the surface of the body 20. The total ventilation area of the opening 22 is larger than the total ventilation area of the inlet 23. The inlet 23 is connected to a A negative pressure source (not shown), which is formed by the driving operation of air extraction equipment such as an air compressor. The negative pressure source extracts the air in the air chamber 21 through the inlet 23 through the negative pressure pipe 60. The air chamber 21 is brought into a negative pressure state, and the device body 20 generates suction at the opening 22.
該透氣膜30是罩設於器體20的開口22處，該透氣膜30上分佈形成有多個透氣孔31，該器體20內的氣室21是通過透氣膜30上的透氣孔31與外界連通，所述多個透氣孔21的佈設面域是大於異形薄片物件90的形體輪廓，使本發明之負壓吸附器能全部罩附到異形薄片物件90。該透氣膜30在實施上可以是由高分子聚合物(例如高分子塑膠、高分子纖維等)製成，使該透氣膜30上的多個透氣孔呈棉隙狀分佈，且所述多個透氣孔31之間的孔隙為10μm~30μm。此外，所述多個透氣孔31的孔洞形狀是因應透氣膜30所選用材料而定，其並非受限於圓形或其它形狀，例如當選用高分子纖維製成該透氣膜30時，所述多個透氣孔31的孔洞形狀可能呈現為條隙狀或絲隙狀交錯分佈；又例如選用高分子塑膠製成該透氣膜30時，所述多個透氣孔31的孔洞形狀可能呈現接近圓形或其它網狀的孔洞。另一層面的說，該透氣膜30可以如同於一般市面上所見由高分子聚合物製成的過濾棉一樣，具有良好的通氣流暢性。 The ventilating film 30 is covered at the opening 22 of the device body 20. A plurality of ventilating holes 31 are formed in the venting film 30. The air chamber 21 in the device body 20 passes through the venting holes 31 and The outside is connected, and the layout area of the plurality of ventilation holes 21 is larger than the profile of the profiled sheet object 90, so that the negative pressure adsorber of the present invention can be completely attached to the profiled sheet object 90. In practice, the breathable film 30 may be made of a polymer (such as polymer plastic, polymer fiber, etc.), so that a plurality of breathable holes in the breathable film 30 are distributed in a cotton-gap shape, and The pores between the vent holes 31 are 10 μm to 30 μm. In addition, the shape of the holes of the plurality of breathable holes 31 is determined by the material selected for the breathable film 30 and is not limited to a circle or other shapes. For example, when polymer fibers are used to make the breathable film 30, The shape of the holes of the plurality of ventilation holes 31 may be staggered or filament-like staggered; for example, when the polymer film 30 is made of polymer plastic, the shape of the holes of the plurality of ventilation holes 31 may be nearly circular. Or other reticulated holes. On the other hand, the air-permeable membrane 30 can have good ventilation and smoothness, just like the filter cotton made of high-molecular polymers seen in the general market.
該擴散板40是介設於透氣膜30與開口22之間，該擴散板40具有一平坦的端面40a，該透氣膜30是組設於該端面 40a上，使透氣膜30能維持平整狀。進一步的說，該擴散板40的端面40a上分佈形成有多個通孔41，該器體20內的氣室21是依序經由通孔41及透氣孔31而與外界連通，其中由於所述多個通孔41在實施上是以機械加工(例如鏜鑽或冲製)製成，使得所述多個通孔41之間的孔隙最小值在0.5mm以上，因此所述多個透氣孔31在該透氣膜30單位面積下所分佈的數量是大於所述多個通孔41在該擴散板40單位面積下分佈的數量，且所述多個透氣孔31之間的孔隙是小於所述多個通孔41之間的孔隙。 The diffusion plate 40 is interposed between the breathable film 30 and the opening 22. The diffusion plate 40 has a flat end surface 40 a. The breathable film 30 is arranged on the end surface. On 40a, the air-permeable membrane 30 can be kept flat. Further, a plurality of through holes 41 are formed on the end surface 40a of the diffusion plate 40. The air chamber 21 in the device body 20 communicates with the outside through the through holes 41 and the ventilation holes 31 in sequence. In practice, the plurality of through holes 41 are made by machining (such as boring or punching), so that the minimum value of the pores between the plurality of through holes 41 is 0.5 mm or more. Therefore, the plurality of ventilation holes 31 The number distributed in the unit area of the air-permeable membrane 30 is larger than the number distributed in the unit area of the plurality of through-holes 41 in the unit area of the diffusion plate 40, and the pores between the plurality of air-permeable holes 31 are smaller than the number Between the through holes 41.
此外，該器體20在實施上可經由一連接座70而配置於一多軸機械臂的爪頭(未繪示)相連接，藉由該多軸機械臂的帶動而使負壓吸附器具有多軸向位移的能力。 In addition, in practice, the device body 20 can be connected to the claw head (not shown) of a multi-axis robotic arm through a connecting seat 70, and the negative pressure adsorber is provided with the driving of the multi-axis robotic arm. Multi-axial displacement capability.
請合併參閱圖4及圖5，揭露本發明之第二種實施例的配置細節，其與上述第一種實施例的差異處在於：該透氣膜30與擴散板40之間還介設有一透氣軟墊50，該透氣軟墊50在實施上是由矽膠或PU製成。當負壓吸附器憑藉多軸機械臂上爪頭的帶動而吸持異形薄片物件90時，負壓吸附器會對異形薄片物件90施加一推力，此時可經由透氣軟墊50來吸收該推力，讓透氣膜30能夠更緊密的接觸異形薄片物件90，進而提升負壓吸附器在吸持異形薄片物件90的牢固性。進一步的說，該透氣軟墊50上分佈形成有多個穿孔51，所述多個穿孔51經由所述多個通孔41而與該氣室21相連通，且所述多個穿孔51經由所述多個透氣孔31而與外界相連通，使該器體20內的氣室21能依序經由通孔41、穿孔51及透氣孔31而與外界連通。在具體實施上，所述多個透氣孔31在該透氣膜30單位面積下所分佈的數量是大於所述多個穿孔51在該透氣軟墊50單位面積下分佈的數量，且所述多個透氣孔31的孔隙是小於所述多個穿孔51。更進一步的說，所述多個穿孔51在該透氣軟墊50單位面積下所分佈的數量可以是與所述多個通孔41在該擴散板40單位面積下分 佈的數量相同，也可以是小於所述多個通孔41在該擴散板40單位面積下分佈的數量。 Please refer to FIG. 4 and FIG. 5 together to disclose the configuration details of the second embodiment of the present invention. The difference from the first embodiment is that a ventilation is provided between the gas-permeable membrane 30 and the diffusion plate 40. A cushion 50, which is made of silicone or PU in practice. When the negative pressure adsorber holds the special-shaped sheet object 90 by the claw head on the multi-axis robotic arm, the negative pressure adsorber applies a thrust to the special-shaped sheet object 90, and the thrust can be absorbed by the air-permeable cushion 50 at this time. In this way, the air-permeable film 30 can more closely contact the shaped sheet object 90, thereby improving the firmness of the negative pressure adsorber in holding the shaped sheet object 90. Further, a plurality of perforations 51 are formed on the breathable cushion 50, and the plurality of perforations 51 communicate with the air chamber 21 through the plurality of through holes 41, and the plurality of perforations 51 are communicated through the air holes 21. The plurality of ventilation holes 31 communicate with the outside, so that the air chamber 21 in the device body 20 can communicate with the outside through the through holes 41, the perforations 51, and the ventilation holes 31 in this order. In specific implementation, the number of the plurality of ventilation holes 31 distributed in the unit area of the breathable film 30 is greater than the number of the plurality of perforations 51 distributed in the unit area of the breathable cushion 50, and the number of The pores of the ventilation holes 31 are smaller than the plurality of perforations 51.
