Description
本發明涉及玻璃加工技術領域,具體地涉及一種多模具熱彎成型設備。The invention relates to the technical field of glass processing, in particular to a multi-die hot bending forming equipment.
由於OLED顯示技術的發展,以及曲面玻璃的高顏值、對訊號無屏蔽的優勢,曲面玻璃將成為各顯示領域的主流蓋板產品。如智能手機、智能手表、平板計算機、可穿戴式智能產品、儀表板等,已經明確引導3D曲面玻璃發展方向。3D曲面玻璃輕薄、透明潔淨、抗指紋、防眩光、堅硬、耐刮傷等優點,以及無線充電機能,解決天線佈置空間不足及增強收訊功能,使產品更美觀出色。比如,現有常用的手機3D曲面玻璃基板成型方法步驟為:①室溫下,空氣環境下,人工將2D平面玻璃基板放到成型模具內;②將裝載玻璃的成型模具投入到密封的、充滿氮氣的隔離室內進行除氧;③成型室內分步通過預熱、熱彎、緩冷定形為3D曲面玻璃基板;④再然後冷卻降溫到室溫;⑤室溫下人工分模,取出成型的3D曲面玻璃基板,再進行下一個循環。Due to the development of OLED display technology, as well as the advantages of curved glass with high appearance and no shielding of signals, curved glass will become the mainstream cover product in various display fields. Such as smart phones, smart watches, tablet computers, wearable smart products, dashboards, etc., have clearly guided the development direction of 3D curved glass. 3D curved glass is thin, transparent, clean, anti-fingerprint, anti-glare, hard, scratch-resistant, etc., as well as wireless charging function, which solves the lack of antenna layout space and enhances the reception function, making the product more beautiful and outstanding. For example, the steps of the existing commonly used mobile phone 3D curved glass substrate forming method are: ①At room temperature, in the air environment, manually put the 2D flat glass substrate into the forming mold; ②Put the forming mold loaded with glass into a sealed, nitrogen-filled mold Deaeration in the isolation room of the mold; ③The molding room is shaped into a 3D curved glass substrate through preheating, hot bending, and slow cooling step by step; ④Then cool down to room temperature; ⑤Manually split the mold at room temperature to take out the molded 3D curved surface Glass substrate, and then go to the next cycle.
但是,由於3D曲面玻璃加工難度大,工藝過程複雜,尤其是熱彎成型工藝,是整體良品率的關鍵環節。而現有熱彎設備的自動化水平低、生產效率低、能源消耗高等方面的不足,使得曲面玻璃熱彎設備存在很大的提升空間。However, due to the difficulty of processing 3D curved glass, the process is complicated, especially the hot bending process, which is a key link in the overall yield rate. However, the existing hot bending equipment has a low level of automation, low production efficiency, and high energy consumption, so that there is a lot of room for improvement in curved glass hot bending equipment.

It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not used to limit the present invention.
參考圖1、圖2和圖5所示的一種實施例的結構,該多模具熱彎成型設備包括依次密封連接的進料裝置1(參見圖2所示的結構)、具有加熱通道2的加熱裝置3(參見圖1所示的結構)、具有成型通道4的成型裝置5(參見圖1所示的結構)、具有退火通道6的退火裝置7(參見圖1所示的結構)和具有出料通道8的出料裝置9(參見圖5所示的結構),進料裝置1包括進料隔離倉10和推料單元11,進料隔離倉10內形成有沿著與推料單元11的推料方向(圖2的圖形介面的左右方向)垂直的布料方向(圖3和圖4的圖形介面的左右方向)延伸的布料通道12,布料通道12內具有多個沿著布料方向間隔佈置的模具定位位置,加熱通道2內具有對應的多個加熱位置,成型通道4內具有對應的多個成型位置(比如,如圖3所示的六個加熱位置,圖4所示的六個成型位置,相應地,布料通道12內具有六個模具定位位置),而沿著推料方向,各個模具定位位置、加熱位置、成型位置能夠相通並能夠與退火通道6和出料通道8相通,推料單元11設置為用於將模具定位位置上佈置的模具推入到加熱通道2內相應的加熱位置上。Referring to the structure of an embodiment shown in Figure 1, Figure 2 and Figure 5, the multi-mold hot bending forming equipment includes a feeding device 1 (see the structure shown in Figure 2) and a heating channel 2 that are sealed and connected in sequence. Device 3 (see the structure shown in FIG. 1), a
在該技術方案中,由於進料隔離倉10內形成有沿著與推料單元11的推料方向垂直的布料方向延伸的布料通道12,並且布料通道12內具有多個沿著布料方向間隔佈置的模具定位位置,加熱通道2內具有對應的多個加熱位置,成型通道4內具有對應的多個成型位置,同時,各個模具定位位置、加熱位置、成型位置能夠相通,這樣,操作人員可以將裝載有玻璃片的多個成型模具30沿著布料方向定位在布料通道12內,在進料隔離倉10內經過除氧處理後,推料單元11可以沿著推料方向將各個成型模具30推入到後續的各自對應的加熱位置、成型位置進行後續處理,並能夠被推入到退火通道6,最後從出料通道8出料,因此,該多模具熱彎成型設備能夠一次對多個成型模具30進行處理,顯著提升了設備運行節拍,從而在達到提高單台設備產能目的的同時,提高了設備生產效率、玻璃成型品質和產品良率。In this technical solution, since the
需要理解的是,本發明的多模具熱彎成型設備中,推料單元11可以以多種方式將模具定位位置上佈置的模具推入到加熱通道2內相應的加熱位置上。比如,一種形式中,沿著布料方向,設置有多個對應的推料單元11,比如推料氣缸,每個推料單元11可以將各自對應的成型模具30以一定時間差推入到對應的加熱位置上。It should be understood that, in the multi-mold hot bending forming equipment of the present invention, the pushing
或者,推料單元11設置為用於將各個模具定位位置上佈置的各個模具同時推入到加熱通道2內相應的加熱位置上並能夠通過上一模具推動下一模具的方式沿著推料方向同時推動各個模具,也就是,成型模具30前進是靠後邊的成型模具30的推動,而推料單元11僅負責推定後續新放入的成型模具30即可,這樣,就省略了現有技術中的用於推動成型模具30向前移動的撥叉,從而使得本發明的多模具熱彎成型設備結構簡單,減少了設備的故障率。Alternatively, the pushing
當然,推料單元11可以為多個並可以設置在進料隔離倉10內,或者,為了減少進料隔離倉10的體積,便於控制多個成型模具30同時被推入到各自對應的加熱位置上,優選地,如圖2所示的,推料單元11包括推板13和進料推動缸14,其中,進料推動缸14的缸體設置在進料隔離倉10的外部並且推桿伸入到布料通道12內,當然,推桿與進料隔離倉10的倉壁是密封滑動配合的,而推板13連接於推桿並沿著布料通道12延伸到各個模具定位位置。這樣,在各個模具定位位置上佈置完成型模具30後,進料推動缸14的推桿伸出,通過推板13將全部的成型模具30一次性推入到加熱通道2內各自對應的加熱位置上。Of course, the pushing
另外,為了便於進料隔離倉10內的除氧完畢後的成型模具30被平順地推入到加熱通道2內,優選地,如圖2所示的,進料裝置1和加熱裝置3之間設置有模具推送過渡板15;進料裝置1包括具有多個模具定位位置的承料板16,承料板16能夠取放地設置在進料隔離倉10內;在承料板16放入到進料隔離倉10內時,承料板16和模具推送過渡板15齊平;比如,進料隔離倉10的倉側壁形成有具有封閉門的出料口,模具推送過渡板15從進料隔離倉10內穿過出料口延伸到外部,比如可以延伸進入到加熱通道2內,當然,模具推送過渡板15外露的部分通過防護罩罩住,以避免成型模具30接觸外部空氣,這樣,操作人員可以將承料板16抽出,並將成型模具30放置在模具定位位置上後插裝到進料隔離倉10內,此時,承料板16和模具推送過渡板15齊平,出料口的封閉門開啟後,推料單元11就可以將成型模具30平順地通過模具推送過渡板15從出料口推出並推入到加熱通道2內;和/或,如圖1所示的,沿著推料方向,多模具熱彎成型設備形成有從布料通道12的模具定位位置開始,延伸通過各自對應的加熱位置、成型位置和退火通道6的退火位置的推料引導槽29。比如,加熱通道2、成型通道4和退火通道6的側壁形成有缺口,並且各個通道內形成有沿著推料方向延伸到引導壁,兩個引導壁和缺口將形成推料引導槽29,順著推料引導槽29,推料單元11就能夠推動各個成型模具30依次有序地通過加熱位置、成型位置和退火位置,避免由於相互干涉而形成卡滯。In addition, in order to facilitate the feeding of the forming
另外,為了減少玻璃的表面缺陷,提升玻璃的成型品質,優選地,如圖2所示的,進料裝置1包括進料驅動裝置17和位於進料隔離倉10內的隔離罩18,隔離罩18上形成有通氣介面,進料驅動裝置17能夠帶動隔離罩18在密封罩住模具定位位置的隔離狀態和離開模具定位位置的非隔離狀態之間轉換。這樣,由於隔離罩18位於進料隔離倉10內並具有密封罩住模具定位位置的隔離狀態,在實際使用中,可以將內部放置有玻璃片的密封較好的成型模具30(比如現有技術中未設置有換氣槽的成型模具)放置在模具定位位置上,然後向進料隔離倉10內注入惰性氣體以置換進料隔離倉10內的空氣,並在進料隔離倉10內使用隔離罩18密封罩住成型模具30以形成隔離密封空間,然後使用外部抽真空設備通過通氣介面對隔離密封空間抽真空以排出隔離密封空間內的空氣、成型模具30的腔室內不易排除的空氣以及成型模具30的間隙間的氧氣,同時,成型模具30內的玻璃表面因靜電吸附的灰塵也被抽吸真空時帶走,從而將成型模具30中的氧氣盡可能排完,然後可以通過外部的補氣裝置通過通氣介面補入惰性氣體,同時,由於成型模具30相對比較密封,成型模具30內外氣體交換量比較少,在後續的作業中因補充惰性氣體比如氮氣流動產生的風塵黏附在玻璃及模具表面上較少,從而減少玻璃產生的表面缺陷,提升玻璃的成型品質。In addition, in order to reduce the surface defects of the glass and improve the molding quality of the glass, preferably, as shown in FIG. 2, the
在本發明的多模具熱彎成型設備中,可以採用多種方式通過通氣介面對隔離密封空間抽吸真空並注入惰性氣體,比如,一種方式中,進料驅動裝置17帶動隔離罩18在隔離狀態和非隔離狀態之間轉換,可以通過額外的柔性管穿過進料隔離倉10的倉壁並連接到通氣介面,柔性管的一端可以連接於通氣介面,另一端可以通過轉換接頭與外部的補氣裝置和抽真空裝置連接,這樣,在隔離狀態,轉換接頭將抽真空裝置和柔性管接通以抽真空,抽真空完成後,轉換接頭將補氣裝置和柔性管接通以補入惰性氣體。In the multi-mold hot bending forming equipment of the present invention, a variety of methods can be used to draw vacuum through the ventilating interface and inject inert gas into the isolated sealed space. For example, in one method, the
或者,另一種方式中,可以利用進料驅動裝置17和隔離罩18之間的連接結構進行抽真空和補氣,比如,參考圖2所示的結構,進料驅動裝置17通過連接管帶動隔離罩18在隔離狀態和非隔離狀態之間轉換,並且連接管的一端連接於通氣介面,這樣,進料驅動裝置17可以僅通過連接管帶動隔離罩18動作,同時,連接管可以作為抽真空管和補氣管。Or, in another way, the connection structure between the
當然,進料驅動裝置17可以設置在任何適當的位置處,比如,進料驅動裝置17可以設置在進料隔離倉10內並固定設置在倉頂壁上,或者,如圖2所示的,進料驅動裝置17固定設置在進料隔離倉10的倉頂壁的外部,連接管穿過倉頂壁並與倉頂壁密封滑動配合。這樣,進料驅動裝置17可以通過連接管帶動隔離罩18下降以接觸進料隔離倉10的倉底壁以處於隔離狀態,或者帶動隔離罩18上升遠離倉底壁而處於非隔離狀態。Of course, the feeding
進一步地,為了提升進料驅動裝置17和連接管連接的便捷性,提升連接管運動的可靠性,優選地,如圖2所示的,進料驅動裝置17的動力輸出端連接有端板34,連接管固定設置在端板34上,圖2中端板34與連接管的佈置關係的另一個視角結構可以參考圖5中顯示的端板34與進水管26和出水管27的佈置關係。這樣,連接管的一端連接於隔離罩18上的通氣介面,另一端從端板34上伸出,以用於連接外部的補氣裝置和抽真空裝置。Further, in order to improve the convenience of the connection between the feeding
端板34的設置還便於將多個管與隔離罩18連接,比如,如圖2所示的,為了提升抽真空和注入惰性氣體的便捷性,連接管包括進氣管19和出氣管20,圖2中端板34與進氣管19和出氣管20的佈置結構可以參考圖5中顯示的端板34與進水管26和出水管27的佈置結構,兩者基本相同,通氣介面包括入氣口和排氣口,其中,進料驅動裝置17設置在進料隔離倉10的外部並通過進氣管19和出氣管20與隔離罩18連接,進氣管19和出氣管20密封滑動地與進料隔離倉10的頂倉壁配合,並分別與入氣口和排氣口連接。這樣,在隔離狀態下,可以通過進氣管19和入氣口向隔離密封空間內注入具有除靜電功能的惰性氣體,然後通過出氣管20和排氣口抽真空,然後再通過進氣管19和入氣口注入惰性氣體。The arrangement of the
當然,進料驅動裝置17可以具有多種形式,比如,進料驅動裝置17可以為氣缸,如圖2所示的,氣缸的活塞桿上連接有端板34。或者,進料驅動裝置17包括提拉桿和設置在提拉桿和進料隔離倉10之間的鎖定機構,該鎖定機構包括鎖定把手,向上提起提拉桿,可以使得隔離罩18處於非隔離狀態,向下移動提拉桿,可以使得隔離罩18接觸倉底壁並通過鎖定機構鎖定而使得隔離罩18處於隔離狀態。Of course, the
另外,可以根據需要在進料隔離倉10內設置相應數量的模具定位位置,比如,進料隔離倉10內形成有多個沿著與推料方向垂直的布料方向間隔佈置的多個模具定位位置,隔離罩18能夠同時密封罩住多個模具定位位置。這樣,通過單一的隔離罩18,就能夠同時對多個成型模具30進行除氧除塵操作。In addition, a corresponding number of mold positioning positions can be set in the
另外,如圖1所示的,加熱裝置3、成型裝置5和退火裝置7分別包括多個加熱通道2、成型通道4和退火通道6,並沿著推料方向佈置,也就是,加熱裝置3可以預熱成型模具30,成型裝置5可以熱彎成型模具30,退火裝置7可以對熱彎後的成型模具30進行退火;這樣,該多模具熱彎成型設備包括玻璃模具預熱區域、熱彎成型區域、退火冷卻區域。根據生產工藝需求共可設置11~20個工位單元,其中預熱區域可設置4~12個工位單元,成型區域可設置2~4個工位單元,退火冷卻區域可設置3~8個工位單元,並行設置6個模具通道以形成六模具熱彎成型設備,可使6個成型模具30同時進行熱彎成型。In addition, as shown in FIG. 1, the
該六模具熱彎設備優選的共設置13個工位單元,其中預熱區域設置7個工位單元,熱彎成型區域設置3個工位單元,退火冷卻區域設置3個工位單元。The six-die hot bending equipment preferably has a total of 13 station units, of which 7 station units are installed in the preheating area, 3 station units are installed in the hot bending forming area, and 3 station units are installed in the annealing cooling area.
預熱區域的玻璃模具預熱的七個工位可以將玻璃模具從室溫加熱到700度左右,滿足玻璃變形溫度。比如,成型模具30每經過一段固定的時間,會從前一加熱工位移動至下一加熱工位進行加熱,經過連續加熱,成型模具30在進入第7個加熱工位時,成型模具30的溫度會被加熱至700度左右,此時,成型模具30內玻璃達到軟化點溫度,成型模具30進入熱彎成型區域。如圖3所示的,上加熱板部分採用可升降結構,當成型模具30移動到加熱工位時,上加熱板下降至和成型模具30上表面接觸位置,以提高加熱效率。上加熱板左側三個通道為一組和右側三個通道為一組,使用連接板31進行連接,升降氣缸帶動連接板31升降,使加熱板上下移動。The seven preheating stations of the glass mold in the preheating zone can heat the glass mold from room temperature to about 700 degrees to meet the glass deformation temperature. For example, after a fixed period of time, the forming
熱彎成型區域的壓製成型的三個工位採用比例閥控制氣缸升降加壓模具成型,每個比例閥控制一個氣缸,每個工位三個氣缸合成一組,如圖4所示的,成型模具30在700度左右時進入第一站成型工位,進行加壓成型,成型壓力根據溫度和玻璃性能等參數具體確定,其壓力範圍約為1000N~2000N之間,成型模具30在第一站成型工位進行成型後,進入下一成型工位繼續加壓定型。成型區域的每個成型通道4都設置有成型氣缸,保證成型時有足夠的壓力對玻璃進行熱彎定型,同時左側三個氣缸為一組和右側三個氣缸為一組,每組氣缸之間設置了基本同步的連接桿32,連接桿32為交叉齒插接結構,保證成型氣缸同步連動的同時每個成型氣缸的成型精確度不會相互影響。每個成型氣缸上都設置有位置檢測儀33,精確確定和控制成型氣缸位置,對於成型模具30內的玻璃成型品質將有顯著提升。The three stations of the press forming area of the hot bending forming area adopt proportional valves to control the cylinder lifting and pressurizing mold forming, each proportional valve controls a cylinder, and each station has three cylinders into a group, as shown in Figure 4, forming The
熱彎成型時,採用加熱管進行加熱,最高升溫溫度可以在800度以上,以滿足玻璃熱彎成型溫度。加熱方式是通過加熱管對加熱板進行加熱,加熱板採用碳化矽板材質製作,碳化矽具有良好的導熱性能,同時熱膨脹係數小,加熱不變形,強度高,然後加熱板支撐成型模具30對成型模具30進行加熱,加熱板作為成型模具30加熱和支撐的載體以具有良好的穩定性和熱均勻性,有助於成型模具30內玻璃成型。同時,在加熱板外側設有隔熱板,隔熱板為耐火材料,具有耐高溫、保溫隔熱,保護周圍零部件的同時,也降低了熱量散失。此外,熱彎成型區域外比如爐體四周包有保溫材料,上保溫板、下保溫板、側保溫板,爐體保溫層有效防止了爐內熱量的散失,減少熱損耗,降低能源消耗。During hot bending, a heating tube is used for heating, and the highest temperature can be above 800 degrees to meet the glass hot bending temperature. The heating method is to heat the heating plate through a heating tube. The heating plate is made of silicon carbide plate. The silicon carbide has good thermal conductivity. At the same time, the coefficient of thermal expansion is small, the heating is not deformed, and the strength is high. Then the heating plate supports the forming
在壓製成型時,模具加熱採用加熱板加熱,單個工位採用六個氣缸帶動六塊加熱板升降,成型過程中設有氣缸行程檢測系統,監控玻璃成型狀態。During press molding, the mold is heated by heating plates, and a single station uses six cylinders to drive six heating plates up and down. A cylinder stroke detection system is installed during the molding process to monitor the glass molding state.
退火冷卻區域的緩冷定型設有三個工位,在退火點附近將玻璃冷卻定型。成型模具30在成型區域中成型並定型完成後,進入退火區域開始進行退火去應力工藝,經過3個退火工位單元,成型模具30的溫度逐漸降低,成型模具30內玻璃溫度也隨之降低,從軟化點降溫至退火點以下,完成退火,之後從成型爐進入出料裝置9的出料隔離倉22。There are three work stations for slow cooling and shaping in the annealing cooling zone, and the glass is cooled and shaped near the annealing point. After the forming
和/或,and / or,
當然,加熱裝置3、成型裝置5和退火裝置7可以單獨的裝置並相互密封連接,或者,為了提升結構的緊湊型,優選地,如圖1所示的,多模具熱彎成型設備包括熱彎爐21,熱彎爐21包括加熱裝置3、成型裝置5和退火裝置7。這樣,通過一熱彎爐21就能夠實現成型模具30內玻璃片的加熱、成型和退火。Of course, the
另外,如圖5所示的,成型模具30冷卻退火後,將進入到出料裝置9,為此,出料裝置9包括出料隔離倉22和出料推動缸23,其中,出料推動缸23的缸體設置在出料隔離倉22的外部,出料推動缸23的推桿伸入到出料通道8內並連接有模具出料承接板24;出料推動缸23能夠帶動模具出料承接板24進出退火通道6。In addition, as shown in FIG. 5, after cooling and annealing, the forming
這樣,成型模具30經過退火區域後,出料推動缸23伸出,帶動模具出料承接板24進入退火區域,成型模具30被推送到模具出料承接板24上,出料推動缸23縮回將模具出料承接板24帶到出料隔離倉22內。In this way, after the forming
進一步地,為了提升成型模具30在出料隔離倉22內的冷卻效果,優選地,如圖5所示的,出料裝置9包括內部形成有冷卻通道的冷卻板25,冷卻板25位於出料隔離倉22內並位於模具出料承接板24上方;冷卻板25與進水管26和出水管27連接,進水管26和出水管27通過端板34與出料驅動裝置28連接,進水管26和出水管27與冷卻通道連通並與出料隔離倉22的頂倉壁密封滑動配合。Further, in order to improve the cooling effect of the forming
這樣,出料推動缸23縮回將模具出料承接板24帶到出料隔離倉22內後,出料驅動裝置28帶動上方的冷卻板25下降,對成型模具30進行冷卻,而通過進水管26和出水管27在冷卻板25內流動的冷卻水則能夠增強冷卻效果。In this way, after the discharging pushing
