***動作之說明*** ***Description of action***

使用圖6,對可將載置有工件99之印刷台70進行旋轉地加以安裝之印刷裝置100之網版印刷方法進行說明。 Using FIG. 6 , the screen printing method of the printing apparatus 100 which can rotatably install the printing table 70 on which the workpiece 99 is placed will be described.

此處,對印刷具有前平坦部991、屈曲部992及後平坦部993之工件99之方法進行說明。 Here, a method of printing a workpiece 99 having a front flat portion 991 , a bent portion 992 and a rear flat portion 993 will be described.

又,對印刷裝置100朝向左方向之印刷動作進行說明。 In addition, the printing operation of the printing apparatus 100 in the left direction will be described.

*準備步驟S10* *Preparation step S10*

若印刷裝置100之電源導通(ON),控制部60便開始進行以下之初始動作。 When the power supply of the printing apparatus 100 is turned on (ON), the control unit 60 starts the following initial operations.

控制部60使滑台561之齒條562朝右側之初始位置移動,並如圖7所示般,使印刷台70以前半部成為水平之方式旋轉。 The control unit 60 moves the rack 562 of the slide table 561 to the initial position on the right side, and rotates the printing table 70 so that the front half thereof becomes horizontal as shown in FIG. 7 .

左邊的擋止器55禁止印刷台70大幅地朝左旋轉。 The left stop 55 prevents the printing table 70 from being rotated substantially to the left.

控制部60藉由未圖示之搬出搬入裝置,將工件99載置於印刷台70,並將工件99配置於網版91之下方。 The control unit 60 places the workpiece 99 on the printing table 70 and arranges the workpiece 99 under the screen 91 by means of a loading/unloading device not shown.

控制部60藉由未圖示之抽吸機構,將工件99抽吸於印刷台70,而將工件99固定於印刷台70。 The control unit 60 sucks the workpiece 99 onto the printing table 70 by a suction mechanism not shown, and fixes the workpiece 99 on the printing table 70 .

控制部60使右邊的汽缸54之桿上升。 The control unit 60 raises the rod of the right cylinder 54 .

右邊的汽缸54,在工件99之前平坦部991與網版91形成為平行之狀態下支撐前平部711之下表面。 The right air cylinder 54 supports the lower surface of the front flat portion 711 in a state where the front flat portion 991 of the workpiece 99 is parallel to the screen 91 .

控制部60使刮刀92朝右側之印刷開始位置移動。 The control unit 60 moves the squeegee 92 to the printing start position on the right side.

*前半印刷步驟S20* *The first half printing step S20*

圖7係顯示前半印刷之圖。 Figure 7 is a diagram showing the first half of printing.

前半印刷步驟S20係將載置有工件99之前平坦部991之印刷台70之前半部固定為與印刷方向平行,並印刷前平坦部991之步驟。 The first half printing step S20 is a step of fixing the front half of the printing table 70 on which the front flat portion 991 of the workpiece 99 is placed parallel to the printing direction, and printing the front flat portion 991 .

控制部60開始刮刀92朝左方向之移動而開始進行印刷。 The control unit 60 starts the movement of the squeegee 92 to the left to start printing.

於前半印刷中,控制部60鎖定滑台561,來禁止印刷台70之旋轉。 In the first half of printing, the control unit 60 locks the slide table 561 to prohibit rotation of the printing table 70 .

於前半印刷中,控制部60停止移動台52之移動。 In the first half of printing, the control unit 60 stops the movement of the moving table 52 .

於前半印刷中,由於右邊的汽缸54支撐前平部711之下表面,因此即便於前平坦部991施加有印刷壓力,印刷台70亦不會進行右旋轉、印刷台70亦不會變形。 In the first half of printing, since the right cylinder 54 supports the lower surface of the front flat portion 711, even if printing pressure is applied to the front flat portion 991, the printing table 70 will not rotate to the right and the printing table 70 will not be deformed.

前半印刷步驟S20會於印刷完工件99之前平坦部991之時間點結束。 The printing step S20 in the first half ends at the time point when the flat portion 991 is printed before the workpiece 99 is printed.

*屈曲印刷步驟S30* *Buckling printing step S30*

圖8係顯示前半印刷後之屈曲印刷之圖。 Figure 8 is a graph showing buckled printing after the first half of printing.

屈曲印刷步驟S30係一邊以工件99之屈曲部992之中心線C為中心使印刷台70旋轉,且一邊使印刷台70朝印刷方向移動一邊印刷屈曲部992之步驟。 The bending printing step S30 is a step of printing the bending portion 992 while rotating the printing table 70 around the center line C of the bending portion 992 of the workpiece 99 and moving the printing table 70 in the printing direction.

控制部60於印刷工件99之屈曲部992之情形時,同時地進行以下之控制。 The control unit 60 simultaneously performs the following controls when printing the bent portion 992 of the workpiece 99 .

(1)使滑台561之齒條562朝左滑動。藉由使齒條562移動而使齒輪77旋轉,從而使印刷台70以旋轉軸75(中心線C)為中心旋轉。 (1) Slide the rack 562 of the slide table 561 to the left. When the gear 77 is rotated by moving the rack 562, the printing table 70 is rotated around the rotation shaft 75 (center line C).

(2)使移動台52相對於框體51朝左方向(印刷方向)移動。 (2) The moving stage 52 is moved in the left direction (printing direction) relative to the housing 51 .

(3)繼續刮刀92朝向左方向(印刷方向)之移動。 (3) Continue to move the scraper 92 toward the left direction (printing direction).

(4)使右側之汽缸54之桿下降。 (4) The rod of the cylinder 54 on the right is lowered.

(5)使左側之汽缸54之桿上升。 (5) Make the rod of the cylinder 54 on the left rise.

於屈曲印刷步驟S30中,藉由使具有較屈曲部992之半徑R大之半徑L之齒輪77旋轉,而使印刷台70旋轉。 In the bending printing step S30 , the printing table 70 is rotated by rotating the gear 77 having a radius L larger than the radius R of the bending portion 992 .

屈曲部992之下表面雖為間隙部76,但由於即便於屈曲部992施加有印刷壓力屈曲部992仍呈凸曲面,因此屈曲部992不會變形。 Although the lower surface of the flexed portion 992 is the gap portion 76 , the flexed portion 992 is still a convex surface even when printing pressure is applied to the flexed portion 992 , so the flexed portion 992 will not be deformed.

屈曲印刷步驟S30會於印刷完工件99之屈曲部992之時間點結束。 The flexure printing step S30 ends when the flexure portion 992 of the workpiece 99 is printed.

*後半印刷步驟S40* *Second half printing step S40*

圖9係顯示屈曲印刷後之後半印刷步驟之圖。 Figure 9 is a diagram showing the second half printing step after flex printing.

後半印刷步驟S40將載置有工件99之後平坦部993之印刷台70之後半部固定為與印刷方向平行,並印刷後平坦部993之步驟。 The second half printing step S40 is a step of fixing the rear half of the printing table 70 on which the rear flat portion 993 of the workpiece 99 is placed parallel to the printing direction, and printing the rear flat portion 993 .

控制部60繼續刮刀92朝向左方向之移動。 The control unit 60 continues the movement of the scraper 92 toward the left.

於後半印刷中,控制部60鎖定滑台561,而禁止印刷台70之旋轉。 In the second half of printing, the control unit 60 locks the slide table 561 and prohibits the rotation of the printing table 70 .

於後半印刷中,控制部60停止移動台52之移動。 In the second half of printing, the control unit 60 stops the movement of the moving table 52 .

於後半印刷中,由於左側之汽缸54支撐後平部713之下表面,因此即便施加有印刷壓力,印刷台70也不會進行左旋轉、印刷台70也不會變形。 In the second half of printing, since the cylinder 54 on the left side supports the lower surface of the rear flat portion 713, even if printing pressure is applied, the printing table 70 will not rotate to the left and the printing table 70 will not be deformed.

後半印刷步驟S40會於印刷完工件99之後平坦部993之時間點結束。 The second half of the printing step S40 ends when the workpiece 99 is printed on the flat portion 993 .

若印刷結束,控制部60便藉由未圖示之搬入搬出裝置,將已結束印刷之工件99搬出。 When the printing is finished, the control unit 60 unloads the printed workpiece 99 by a loading and unloading device (not shown).

控制部60於工件99之搬出後,判斷是否有下一個印刷,於存在有下一個印刷之情形時,返回準備步驟S10。 After the workpiece 99 is unloaded, the control unit 60 judges whether there is a next printing, and if there is a next printing, it returns to the preparation step S10.

控制部60若無下一個印刷,便結束印刷。 If there is no next printing, the control unit 60 ends printing.

●屈曲印刷步驟S30之控制 ●Control of buckling printing step S30

使用圖5,對屈曲印刷步驟S30之細節進行說明。 The details of the buckling printing step S30 will be described using FIG. 5 .

於屈曲部992之圓弧之半徑為R且內角為K度之情形時,屈曲部992之圓弧長度E將成為如下。 When the radius of the arc of the flexing portion 992 is R and the inner angle is K degrees, the length E of the arc of the flexing portion 992 will be as follows.

圓弧長度E=直徑×圓周率×圓弧相對於圓周之比=(2×半徑R)×3.14×(K度÷360度) Arc length E = diameter × pi × ratio of arc to circumference = (2 × radius R) × 3.14 × (K degree ÷ 360 degree)

作為具體例,於半徑R=5mm、K度=35度之情形時,屈曲部992之圓弧長度E將成為如下。 As a specific example, in the case where the radius R=5mm and the degree K=35 degrees, the arc length E of the bending portion 992 will be as follows.

圓弧長度E=(2×5mm)×3.14×(35度÷360度)=10×3.14×35÷360=3.05277≒3.05mm Arc length E=(2×5mm)×3.14×(35°÷360°)=10×3.14×35÷360=3.05277≒3.05mm

控制部60具體地進行以下之控制。 The control unit 60 specifically performs the following control.

(1)以使齒輪77順時針地旋轉35度之方式使滑台561之齒條562朝左滑動。藉由使齒輪77順時針旋轉35度之程度,來使旋轉台70以旋轉軸75為中心順時針地旋轉35度之程度。 (1) Slide the rack 562 of the slide table 561 to the left so that the gear 77 is rotated clockwise by 35 degrees. By rotating the gear 77 clockwise by 35 degrees, the turntable 70 is rotated clockwise by 35 degrees around the rotation shaft 75 .

(2)使移動台52相對於框體51朝左方向(印刷方向)移動3.05mm。 (2) Move the moving stage 52 to the left (printing direction) by 3.05 mm relative to the housing 51 .

(3)使刮刀92朝向左方向(印刷方向)移動3.05mm。 (3) Move the squeegee 92 to the left (printing direction) by 3.05 mm.

***實施形態1之效果的說明*** ***Description of Effects of Embodiment 1***

習知之曲面印刷機構係對平緩之曲面進行處理者,但存在有不適合於具有較小半徑之曲面之印刷的情形。 The known curved surface printing mechanism deals with gentle curved surfaces, but there are situations where it is not suitable for printing on curved surfaces with small radii.

根據實施形態1,可對具有較小半徑之圓弧之屈曲部進行印刷。 According to Embodiment 1, it is possible to print the curved portion having a circular arc with a small radius.

根據實施形態1,由於齒輪77之半徑M較工件99之屈曲部992之半徑R大,因此可使其進行高精度之旋轉。 According to Embodiment 1, since the radius M of the gear 77 is larger than the radius R of the bending portion 992 of the workpiece 99, it can be rotated with high precision.

根據實施形態1,藉由僅製作彎曲角度與工件99之彎曲角度相同之底板71,而可與印刷台70之其他零件共同使用。 According to Embodiment 1, by making only the bottom plate 71 whose bending angle is the same as that of the workpiece 99, it can be used in common with other parts of the printing table 70.

連桿機構30將曲柄軸211之直線運動轉換為以屈曲部992之中心線C為中心之印刷台70之旋轉運動。 The link mechanism 30 converts the linear motion of the crank shaft 211 into the rotational motion of the printing table 70 centered on the center line C of the flexure portion 992 .

***動作之說明*** ***Description of action***

藉由圖16,對屈曲印刷步驟S30進行說明。 Referring to FIG. 16 , the buckling printing step S30 will be described.

*屈曲印刷步驟S30* *Buckling printing step S30*

圖16係顯示前半印刷後之屈曲印刷之圖。 Figure 16 is a graph showing flex printing after the first half of printing.

控制部60於印刷工件99之屈曲部992之情形時,使曲柄軸211朝左上滑動。 The control unit 60 slides the crank shaft 211 upward and leftward when the bent portion 992 of the workpiece 99 is printed.

控制部60藉由使曲柄軸211朝左上前進移動,將支承部220朝上方上推。 The control unit 60 pushes the support unit 220 upward by moving the crank shaft 211 upward and leftward.

支承部220以旋轉軸75(中心線C)為中心朝順時針方向進行旋轉,使印刷台70以旋轉軸75(中心線C)為中心朝順時針方向旋轉。 The support unit 220 rotates clockwise about the rotating shaft 75 (center line C), and rotates the printing table 70 clockwise about the rotating shaft 75 (center line C).

汽缸接頭212由於藉由U型掛鉤230可相對於移動台52旋轉地被安裝,因此若支承部220朝上方被上推,曲柄汽缸210之相對於水平方向之傾斜角度變大。 Since the cylinder joint 212 is rotatably attached to the moving table 52 by the U-shaped hook 230, when the supporting part 220 is pushed upward, the inclination angle of the crank cylinder 210 relative to the horizontal direction becomes large.

由於曲柄軸211係藉由支承部220而可旋轉地安裝於印刷台70,因此若朝上方推壓支承部220,曲柄軸211相對於水平方向之傾斜角度便會變大。 Since the crankshaft 211 is rotatably attached to the printing table 70 via the support part 220, when the support part 220 is pushed upward, the inclination angle of the crankshaft 211 relative to the horizontal direction increases.

於屈曲印刷步驟S30中,利用曲柄機構200將印刷台70上推,藉此使印刷台70旋轉。 In the bending printing step S30 , the printing table 70 is pushed up by the crank mechanism 200 , thereby rotating the printing table 70 .

於將支承部220之銷221與中心軸C之距離設為L、且使印刷台70旋轉K度之情形時,銷221會移動之圓弧長度P將成為如下。 When the distance between the pin 221 of the supporting portion 220 and the central axis C is L and the printing table 70 is rotated by K degrees, the arc length P over which the pin 221 moves is as follows.

圓弧長度P=直徑×圓周率×圓弧相對於圓周之比=(2×半徑L)×3.14×(K度÷360度) Arc length P = diameter × pi × ratio of arc to circumference = (2 × radius L) × 3.14 × (K degrees ÷ 360 degrees)

控制部60當銷221移動圓弧長度P時,以銷221等速地進行移動之方式使曲柄軸211前進移動。 When the pin 221 moves by the arc length P, the control unit 60 moves the crankshaft 211 forward so that the pin 221 moves at a constant speed.

如於實施形態1中所述般,在屈曲部992之圓弧半徑為R且內角為K度之情形時,藉由銷221移動圓弧長度P,圓弧長度E之屈曲部992會被印刷。 As described in Embodiment 1, when the radius of the arc of the flexion portion 992 is R and the inner angle is K degrees, the flexion portion 992 of the arc length E is moved by the pin 221 by the arc length P. print.

***實施形態2之變形例1*** **Modification 1 of Embodiment 2****

●驅動部56之配置 ●Arrangement of the driving unit 56

於圖13中,驅動部56雖與屈曲部992交叉而被配置,但也可僅被配置於屈曲部992之左側、或僅被配置於屈曲部992之右側。 In FIG. 13 , although the drive unit 56 is arranged to intersect the flexure portion 992 , it may be arranged only on the left side of the flexure portion 992 or only on the right side of the flexure portion 992 .

於圖14中,驅動部56亦可並非印刷台70之下表面的左側,而被配置於下表面中央。 In FIG. 14 , the drive unit 56 may be arranged not on the left side of the lower surface of the printing table 70 but in the center of the lower surface.

***實施形態2之變形例2*** **Modification 2 of Embodiment 2****

●連桿機構30 Link mechanism 30

連桿機構30不限定為曲柄機構200,只要為將直線運動轉換為以屈曲部992之中心線C為中心之印刷台之旋轉運動的機構即可。 The link mechanism 30 is not limited to the crank mechanism 200 , and any mechanism may be used as long as it converts linear motion into rotational motion of the printing table centered on the centerline C of the flexure portion 992 .
