當右方向印刷時，將左側之印刷結束位置直接作為左側之印刷開始位置，且以與右方向印刷時相反的動作進行印刷。 When printing in the right direction, the printing end position on the left side is directly used as the printing start position on the left side, and printing is performed in the reverse operation of the printing in the right direction.

控制部70若判斷為無下一印刷，則結束印刷。 When the control unit 70 determines that there is no next printing, it ends the printing.

***第一實施形態之特徵*** ***Features of the first embodiment***

於第一實施形態中，於2個刮刀之間配置刮板，且於2個刮刀 與刮板之間配置漿料。因此，於左右方向之任一印刷中，皆於印刷方向之前方配置有刮板，且於後方配置有刮刀。 In the first embodiment, the squeegee is arranged between the 2 squeegees, and the 2 squeegee The slurry is arranged between the scraper. Therefore, in any printing in the left-right direction, the squeegee is arranged in front of the printing direction, and the squeegee is arranged in the rear.

左右之刮刀與刮板之間的漿料，在去程印刷時一側之漿料被利用在刮板之塗佈，而另一側之漿料被利用在刮刀之印刷，在回程印刷時另一側之漿料被利用在刮板之塗佈，而一側之漿料被利用在刮刀之印刷。 The slurry between the left and right squeegees and the squeegee is used for the coating of the squeegee during the outgoing printing, and the slurry on the other side is used for the printing of the squeegee. The paste on one side is used for squeegee coating, and the paste on one side is used for squeegee printing.

***第一實施形態之功效之說明*** ***Description of the effect of the first embodiment***

根據第一實施形態，在去程及回程可印刷，從而可提高印刷效率。 According to the first embodiment, printing can be performed on the outgoing pass and the return pass, so that the printing efficiency can be improved.

根據第一實施形態，左方向之印刷之印刷開始位置與右方向之印刷之印刷結束位置相同，且左方向之印刷之印刷結束位置與右方向之印刷之印刷開始位置相同。因此，當朝左右方向切換時，只要進行左右刮刀之升降動作，不需要左右移動頭部110，此外，無須使刮板30上下，可提高印刷效率。 According to the first embodiment, the printing start position of the printing in the left direction is the same as the printing end position of the printing in the right direction, and the printing end position of the printing in the left direction is the same as the printing start position of the printing in the right direction. Therefore, when switching in the left-right direction, the head 110 does not need to be moved left and right as long as the left and right squeegees are moved up and down, and the printing efficiency can be improved without moving the squeegee 30 up and down.

***比較例*** ***Comparative Example***

對第一實施形態之構成與在刮刀之後方具有刮板而在去程時進行塗佈而在回程時進行印刷之構成進行比較。 The constitution of the first embodiment is compared with the constitution in which a squeegee is provided behind the squeegee, and the coating is performed on the outgoing route and the printing is performed on the return route.

如第一實施形態，僅在去程時或僅在回程時進行塗佈並進行印刷之情況，與在去程時進行塗佈而在回程時進行印刷之情況比較，具有如下之特徵。 As in the first embodiment, the case where coating and printing are performed only on the outgoing journey or only the return journey has the following characteristics compared with the case where the coating is performed on the outgoing journey and printing is performed on the return journey.

1.於第一實施形態中，由於以一次之移動動作進行塗佈及印刷，因此，與在去程時進行塗佈而在回程時進行印刷之情況比較， 漿料不會乾燥，可提高印刷精度。 1. In the first embodiment, since the coating and printing are performed in one moving operation, compared with the case where the coating is performed on the outgoing journey and the printing is performed on the return journey, The paste does not dry out, which improves printing accuracy.

2.於第一實施形態中，印刷方向與塗佈方向相同，與此相對，在去程時進行塗佈而在回程時進行印刷之情況，印刷方向與塗佈方向相反。 2. In the first embodiment, the printing direction is the same as the coating direction. On the other hand, when coating is performed on the outgoing route and printing is performed on the returning route, the printing direction is opposite to the coating direction.

3.於第一實施形態中，於刮刀與刮板之間始終具有漿料，因此可將去程之印刷結束位置與回程之印刷開始位置設為相同，相對於此，在去程時進行塗佈而在回程進行印刷之情況，由於印刷後之漿料在刮刀之外側，因此需要使刮板上升而越過漿料，從而產生不必要之動作。 3. In the first embodiment, there is always a paste between the squeegee and the squeegee, so the printing end position of the outgoing pass and the printing start position of the return pass can be set to be the same. In the case of printing on the return process, since the paste after printing is outside the squeegee, it is necessary to raise the squeegee to pass over the paste, resulting in unnecessary movement.

4.在去程時進行塗佈而在回程進行印刷之情況，由於刮板位於刮刀之後方，因此刮板有可能對離網產生影響。於第一實施形態中，由於刮刀之後方無任何構件，因此可提供與普通之印刷相同的離網。 4. In the case of coating on the outgoing route and printing on the return route, since the squeegee is located behind the squeegee, the squeegee may have an impact on the off-screen. In the first embodiment, since there is no member behind the squeegee, it can provide the same off-screen as ordinary printing.

根據第一實施形態，可一面塗佈一面進行印刷，無須一面進行印刷一面進行用以下一印刷的塗佈，因此可完成高品質之印刷。 According to the first embodiment, it is possible to perform printing on one side of the coating, and it is not necessary to perform the coating for the next printing while performing the printing on one side, so that high-quality printing can be accomplished.

***第一實施形態之第一變形例*** ***First modification of the first embodiment***

(感測器80) (sensor 80)

圖8之網版印刷裝置100具有感測器80。 The screen printing apparatus 100 of FIG. 8 has the sensor 80 .

感測器80係計測刮板30之下端部39與網版90之間隔的間隙檢測感測器。 The sensor 80 is a gap detection sensor for measuring the gap between the lower end 39 of the squeegee 30 and the screen 90 .

於右方向印刷時，右側之感測器80計測右側之銳角部32之下端與網版90之間隔，且傳送至控制部70。 When printing in the right direction, the sensor 80 on the right side measures the distance between the lower end of the acute corner portion 32 on the right side and the screen 90 , and transmits it to the control unit 70 .

於左方向印刷時，左側之感測器80計測左側之銳角部32之下 端與網版90之間隔，且傳送至控制部70。 When printing in the left direction, the sensor 80 on the left side measures under the acute corner 32 on the left side The distance between the terminal and the screen 90 is transmitted to the control unit 70 .

控制部70以刮板30之下端部39與網版90之間隔成為零之方式驅動刮板上下驅動部53，於印刷中動態地調整刮板30之上下位置。 The control unit 70 drives the squeegee upper and lower drive unit 53 so that the distance between the lower end 39 of the squeegee 30 and the screen 90 becomes zero, and dynamically adjusts the upper and lower positions of the squeegee 30 during printing.

如圖8所示，印刷時，由於網版90藉由刮刀而朝下方被按壓，因此網版90於印刷位置朝下方下降，且網版90於印刷位置之左右產生傾斜。 As shown in FIG. 8 , during printing, since the screen plate 90 is pressed downward by the squeegee, the screen plate 90 descends downward at the printing position, and the screen plate 90 is inclined to the left and right of the printing position.

印刷時之網版90之下降距離係依據網版90與工件900的距離。此外，印刷時之網版90之傾斜角度係隨印刷位置之移動而變化。 The descending distance of the screen 90 during printing depends on the distance between the screen 90 and the workpiece 900 . In addition, the inclination angle of the screen plate 90 during printing changes with the movement of the printing position.

因此，若刮板30之位置被固定，則刮板30之下端部39有可能與網版90分離。 Therefore, if the position of the squeegee 30 is fixed, the lower end portion 39 of the squeegee 30 may be separated from the screen 90 .

感測器80係於頭部110之移動中計測刮板30之下端部39與網版90的間隔。 The sensor 80 measures the distance between the lower end 39 of the squeegee 30 and the screen 90 during the movement of the head 110 .

控制部70驅動刮板上下驅動部53，於頭部110之移動中及時地調整刮板30之上下位置。 The control part 70 drives the upper and lower driving part 53 of the scraper to adjust the upper and lower positions of the scraper 30 in time during the movement of the head 110 .

因此，於印刷中，刮板30之下端部39與網版90始終可保持接觸或接近的狀態。 Therefore, during printing, the lower end portion 39 of the squeegee 30 and the screen plate 90 can always be kept in contact or close to each other.

刮板30之上下位置係被調整在網版90之高度位置T1與工件900之高度位置T3之間的高度位置T2。 The upper and lower positions of the squeegee 30 are adjusted at a height position T2 between the height position T1 of the screen plate 90 and the height position T3 of the workpiece 900 .

當右方向印刷時，T2自左側之印刷開始位置朝向右側之印刷結束位置而逐漸增高。 When printing in the right direction, T2 gradually increases from the printing start position on the left to the printing end position on the right.

當左方向印刷時，T2自右側之印刷開始位置朝向左側之印刷結束位置而逐漸增高。 When printing in the left direction, T2 gradually increases from the printing start position on the right side toward the printing end position on the left side.

***第一實施形態之第二變形例*** ***Second modification of the first embodiment***

(2個刮板30) (2 scrapers 30)

圖9之網版印刷裝置100具有2個刮板30。 The screen printing apparatus 100 of FIG. 9 has two squeegees 30 .

2個刮板30於初始設定時被設定在設定高度位置T2。 The two scrapers 30 are set at the set height position T2 at the time of initial setting.

右側之刮板30被固定於第一刮刀10，因此若第一刮刀上下驅動部51將右側之刮板30設定於印刷高度位置T3，則右側之刮板30被設定於設定高度位置T2。 The right squeegee 30 is fixed to the first squeegee 10. Therefore, if the first squeegee vertical drive unit 51 sets the right squeegee 30 at the printing height position T3, the right squeegee 30 is set at the set height position T2.

左側之刮板30被固定於第二刮刀20，因此若第二刮刀上下驅動部52將左側之刮板30設定於印刷高度位置T3，則左側之刮板30被設定於設定高度位置T2。 The left squeegee 30 is fixed to the second squeegee 20. Therefore, if the second squeegee up-down drive unit 52 sets the left squeegee 30 at the printing height position T3, the left squeegee 30 is set at the set height position T2.

於本例中，不需要刮板上下驅動部53。 In this example, the upper and lower driving parts 53 of the scraper are not required.

***第一實施形態之第三變形例*** ***The third modification of the first embodiment***

(印刷壓力變更印刷) (Printing pressure change printing)

亦可變更左方向之印刷壓力及右方向之印刷壓力。 The printing pressure in the left direction and the printing pressure in the right direction can also be changed.

於變更左方向之印刷壓力及右方向之印刷壓力之情況下，亦可於圖4之工件設置步驟S1及S4中，配合印刷壓力變更刮板30之設定高度位置T2。印刷壓力大之情況，相較於印刷壓力小之情況，只要降低刮板30之設定高度位置T2即可。 In the case of changing the printing pressure in the left direction and the printing pressure in the right direction, the set height position T2 of the squeegee 30 can also be changed in accordance with the printing pressure in the workpiece setting steps S1 and S4 in FIG. 4 . In the case of high printing pressure, compared with the case of low printing pressure, it is only necessary to lower the set height position T2 of the squeegee 30 .

***第一實施形態之第四變形例*** ***Fourth modification of the first embodiment***

(重疊印刷) (overlapping printing)

亦可對相同之工件進行左方向與右方向之重疊印刷。 It is also possible to perform overlapping printing in the left and right directions on the same workpiece.

於進行重疊印刷之情況下，只要於圖4之工件設置步驟S4中，不交換工件900而直接對同一工件900進行即可。 In the case of performing overlapping printing, in the workpiece setting step S4 of FIG. 4 , the workpiece 900 may be directly performed without exchanging the workpiece 900 .

***第一實施形態之第五變形例*** ***Fifth modification of the first embodiment***

(曲面印刷) (curved printing)

亦可對具有曲面的工件進行印刷。 Workpieces with curved surfaces can also be printed.

於對具有曲面的工件進行印刷之情況下，只要於圖4之右方向印刷步驟S3中，控制部70以沿工件900之曲面之方式使第一刮刀10之印刷高度位置T3與刮板30之設定高度位置T2變化即可。同樣地，只要於圖4之左方向印刷步驟S6中，控制部70以沿工件900之曲面之方式使第二刮刀20之印刷高度位置T3與刮板30之設定高度位置T2變化即可。 In the case of printing a workpiece with a curved surface, as long as in the printing step S3 in the right direction of FIG. 4 , the control unit 70 makes the printing height position T3 of the first squeegee 10 and the squeegee 30 close to each other along the curved surface of the workpiece 900 . The set height position T2 can be changed. Similarly, in the printing step S6 in the left direction of FIG. 4 , the control unit 70 can change the printing height position T3 of the second squeegee 20 and the set height position T2 of the squeegee 30 along the curved surface of the workpiece 900 .

即使工件900之曲面之形狀左右不同而左右非對稱，只要預先記憶工件900之曲面形狀，控制部70仍可從工件900之曲面之形狀計算印刷高度位置T3及設定高度位置T2。 Even if the shape of the curved surface of the workpiece 900 is different and asymmetrical, the control unit 70 can still calculate the printing height position T3 and set the height position T2 from the shape of the curved surface of the workpiece 900 as long as the shape of the curved surface of the workpiece 900 is memorized in advance.

或者，只要藉由未圖示之形狀檢測感測器檢測工件900之曲面形狀，控制部70即可從工件900之曲面形狀計算印刷高度位置T3及設定高度位置T2。 Alternatively, the control unit 70 can calculate the printing height position T3 and set the height position T2 from the curved surface shape of the workpiece 900 as long as the shape of the curved surface of the workpiece 900 is detected by a shape detection sensor not shown.

***第一實施形態之第六變形例*** ***Sixth modification of the first embodiment***

(雙工件印刷) (Double workpiece printing)

如圖10所示，亦可將第一刮刀10與第二刮刀20之位置於寬度方向上錯開。 As shown in FIG. 10 , the positions of the first scraper 10 and the second scraper 20 can also be staggered in the width direction.

印刷工作台910係於寬度方向具有2個，可於寬度方向配置2 個工件900。印刷工作台910可上下移動或者可於寬度方向移動，未圖示之工件搬出搬入裝置進行交換工件900。 The printing table 910 has two in the width direction, and can be arranged in two in the width direction 900 workpieces.
