Next, a process of executing the printing process on the substrate S while the printing device 20 cleans the screen mask M will be described. FIG. 5 is a flowchart showing an example of a print processing routine executed by the CPU of the control unit 21. 6 and 7 are explanatory views of the operations of the first board working unit 30, the second board working unit 40, and the processing unit 50, and are explanatory views of a series of operations in the printing process. 6 (a) is an initial state, FIG. 6 (b) is a cleaning process of the substrate S in the first lane, and FIG. 6 (c) is an explanatory diagram of acquiring the position of the substrate S in the first lane. Further, FIG. 7A shows the printing of the substrate S in the first lane and the cleaning process of the substrate S in the second lane, and FIG. 7B shows the printing of the substrate S in the first lane and the position of the substrate S in the second lane. FIG. 7 (c) is an explanatory diagram of acquisition, printing of the substrate S in the second lane, and position acquisition processing of the substrate S in the first lane. Here, the printing process and the cleaning process will be specifically described with reference to FIGS. 6 and 7.

The print processing routine is stored in the HDD of the control unit 21, and is executed after the operator instructs the printing device 20 to perform the printing process. In the initial position, the first substrate working unit 30 and the second substrate working unit 40 are arranged downward, and the processing unit 50 is arranged in a retracted area outside the area of the mask fixing unit 27 (FIG. 6A). When the print processing routine is executed, the CPU of the control unit 21 conveys the board S to the first board work unit 30 (first lane) (step S100). At this time, the first substrate working unit 30 drives the conveyor 31 to carry in the substrate S (FIG. 6A).

Next, the control unit 21 moves the processing unit 50 upward (first lane) of the first substrate working unit 30 (step S110). Next, the control unit 21 determines whether or not it is the cleaning timing of the area (pattern hole 11) of the screen mask M used in the first lane (step S120). When it is the cleaning timing of the screen mask M on the first lane side, the control unit 21 causes the area of the screen mask M used in the first lane to be cleaned (step S130). The cleaning timing is appropriately set at a timing at which the printing process can be appropriately performed, for example, when a predetermined number of substrates S are printed or when a predetermined time has elapsed. At this time, the cleaning unit 60 moves to a position on the Y axis where the wiping member 63 is located in the lower region of the pattern hole 11, raises the pressing member 64, and presses the wiping member 63 against the lower surface of the screen mask M. .. In this state, the processing unit 50 moves on the Y-axis slider 54 and wipes the entire area of the pattern hole 11 with the wiping member 63 (FIG. 6B). The wiping member 63 is wound around the winding roller 62 by rotationally driving the winding roller 62 with or after the processing unit 50 moves.

After step S130, or when it is not the cleaning timing on the first lane side in step S120, the first substrate working unit 30 raises the support member elevating portion 35 so that the upper surface of the substrate S is aligned with the upper surface of the substrate guide 32. The board guide 32 is moved to the board S side to fix the board S. Next, the control unit 21 causes the processing unit 50 to execute the imaging process of the substrate S and the screen mask M in the first lane (step S140, FIG. 6C). At this time, the processing unit 50 images the identification unit formed at a predetermined position on the substrate S by the first imaging unit 56. Further, the control unit 21 acquires the captured image from the first imaging unit 56, and obtains the positional deviation of the substrate S in the first substrate working unit 30 based on the position of the identification unit. As shown in FIG. 6C, the first imaging unit 56 is arranged in front of the carriage 51, and does not easily interfere with the processing of the second substrate working unit 40 when imaging the first substrate working unit 30. ..

After step S140, the control unit 21 moves the processing unit 50 upward (second lane) of the second substrate working unit 40 (step S150). Next, the control unit 21 adjusts the positions of the substrate S fixed to the first substrate working unit 30 and the pattern hole 11 of the screen mask M so as to be at appropriate positions, and first on the lower surface of the screen mask M. The substrate working portion 30 is attracted and fixed (step S160). The control unit 21 causes the mask working unit 26 to adjust the position based on the information of the positional deviation obtained from the imaging result of the first imaging unit 56 described above, so as to eliminate the positional deviation. Further, the first substrate working unit 30 supplies a negative pressure to the suction unit 33 to bring the screen mask M and the substrate guide 32 into close contact with each other. By doing so, even if the processing (cleaning processing, etc.) is performed in parallel on the second lane side, the correct printing result can be obtained on the first lane side (see FIG. 7A described later). ). Subsequently, the control unit 21 starts printing in the first lane (first substrate working unit 30 side) (step S170, FIG. 7B). At this time, the printing processing unit 22 moves the printing head 23 on the screen mask M on the first lane side, pressurizes and discharges the solder paste from the printing head 23, and moves the squeegee 25 back and forth to transfer the solder paste to the substrate. Print on S.

When the printing process in the first lane is started, the control unit 21 determines whether or not the production process is completed based on whether or not there is a substrate S to be printed next (step S180), and the production process is performed. When is not completed, the control unit 21 conveys the substrate S to the second substrate working unit 40 (second lane) (step S190), and at the same time, the area of the screen mask M used in the second lane (pattern hole 12). It is determined whether or not it is the cleaning timing of (step S200). When it is time to clean the screen mask M on the second lane side, the control unit 21 causes the area of the screen mask M used in the second lane to be cleaned (step S210, FIG. 7A). Here, the second substrate working unit 40 performs the same processing as the first substrate working unit 30 described above, and a specific description thereof will be omitted below. The control unit 21 may execute two or more processes that can be combined in parallel, such as a printing process, a transfer process of the substrate S, an imaging process of the substrate S, and a cleaning process of the screen mask M. After step S210, or when it is not the cleaning timing on the second lane side in step S200, the control unit 21 causes the second substrate working unit 40 to support and fix the substrate S. Next, the control unit 21 causes the processing unit 50 to execute the imaging process of the substrate S and the screen mask M in the second lane (step S220, FIG. 7B). As shown in FIGS. 7A and 7B, the second imaging unit 57 is arranged behind the carriage 51, and when the second substrate working unit 40 is imaged, the first substrate working unit 30 It does not interfere with the processing. In the same manner as described above, the control unit 21 acquires the captured image from the second imaging unit 57 and obtains the positional deviation of the substrate S in the second substrate working unit 40 based on the position of the identification unit.

After step S220, the control unit 21 determines whether or not the production process is completed (step S230), and when the production process is not completed, the processing unit 50 is placed above the first substrate working unit 30 (first). (Lane) (step S240). Next, the control unit 21 adjusts the positions so that the substrate S fixed to the second substrate working unit 40 and the pattern hole 12 of the screen mask M are at appropriate positions, and the second substrate M is placed on the lower surface of the screen mask M. The substrate working portion 40 is attracted and fixed (step S250). At this time, the second substrate working unit 40 supplies a negative pressure to the suction unit 43 to bring the screen mask M and the substrate guide 42 into close contact with each other. By doing so, even if the processes (cleaning process, etc.) are performed in parallel on the first lane side, a correct print result can be obtained on the second lane side.

Subsequently, the control unit 21 starts printing in the second lane (second substrate work unit 40 side) (step S260, FIG. 7C), and executes the processes after step S120. That is, the control unit 21 performs an imaging process and a cleaning process in the first lane in parallel with the printing process in the second lane. In the printing process in the second lane, the print processing unit 22 moves the print head 23 on the screen mask M on the second lane side, pressurizes and discharges the solder paste from the print head 23, and moves the squeegee 25 back and forth. The solder paste is printed on the substrate S. On the other hand, when the production process is completed in step S180 or step S230, the control unit 21 moves the first board work unit 30 and the second board work unit 40 downward, and moves the processing unit 50 to the evacuation area. (Step S270), this routine is terminated as it is.

Here, the correspondence between the components of the present embodiment and the components of the present invention will be clarified. The mask fixing portion 27 of the present embodiment corresponds to the fixing portion of the present invention, the first substrate working portion 30 corresponds to the first substrate working portion, and the second substrate working portion 40 corresponds to the second substrate working portion. The processing unit 50 corresponds to the processing unit, and the control unit 21 corresponds to the control unit. Further, the first imaging unit 56 corresponds to the first imaging unit, the second imaging unit 57 corresponds to the second imaging unit, the carriage 51 corresponds to the moving unit, and the suction unit 33 corresponds to the first suction unit. The suction unit 43 corresponds to the second suction unit, and the cleaning unit 60 corresponds to the cleaning unit. In the present embodiment, an example of the printing method of the present invention is also clarified by explaining the operation of the printing device 20.

The printing apparatus 20 of the embodiment described above includes a plurality of board working parts, one board working part executes a printing process, and the other board working part performs an imaging process of an identification part of the board S in parallel. And execute. In this printing apparatus, since the identification unit of another substrate S can be imaged to prepare for the next printing process during printing of the substrate S, the time required for the entire printing process can be further shortened. Further, in the printing apparatus 20, the processing unit 50 performs the imaging process of the substrate S in the first substrate working unit 30 and the imaging process of the substrate S in the second substrate working unit 40 in combination, which is required for the printing process. The device configuration can be further simplified while further reducing the time. Further, in the printing apparatus 20, the second imaging unit 57 is arranged on the first substrate working unit 30 side in a state where the carriage 51 is arranged between the first substrate working unit 30 and the second substrate working unit 40. The first imaging unit 56 is arranged on the second substrate working unit 40 side. In this printing device 20, when the first imaging unit 56 images the substrate S of the first substrate working unit 30 during the printing process by the second substrate working unit 40, the carriage 51 is on the first substrate working unit 30 side. Located in. On the other hand, when the second imaging unit 57 images the substrate S of the second substrate working unit 40 during the printing process by the first substrate working unit 30, the carriage 51 is located on the second substrate working unit 40 side. Therefore, in the printing apparatus 20, the first substrate working portion 30 and the second substrate working portion 40 can be brought closer to each other, and the time required for the printing process can be further shortened, and the apparatus can be made more compact. Can be done.

Further, in the printing apparatus 20, the screen mask M and the second substrate working unit 40 are brought into close contact with each other by the suction unit 43 when printing in the second lane, and the screen mask M and the first screen mask M are brought into close contact with each other by the suction unit 33 when printing in the first lane. Since the substrate working portion 30 is brought into close contact with the substrate working portion 30 to be attracted and supported, the bending of the screen mask M can be further suppressed, and a stable printing process can be performed. In particular, when the cleaning process is performed on one substrate working portion, the screen mask M bends upward, and in the other substrate working portion, the substrate S and the screen mask M are likely to be separated or misaligned, resulting in poor print quality. Although it is easy to do, the suction portions 33 and 43 can further suppress such deterioration of print quality. Further, in the printing apparatus 20, the mask working unit 26 fixes and holds the screen mask M in which the pattern for the first substrate working unit 30 and the pattern for the second substrate working unit 40 are formed on one sheet, and the mask working unit 26 moves the screen mask M based on the imaging result of the substrate position acquisition unit 55 to correct the position between the screen mask M and the substrate S. In this printing apparatus 20, since the relative position correction between the substrate S and the screen mask M can be performed with one configuration, the apparatus configuration can be further simplified while further shortening the time required for the printing process. Furthermore, since the printing apparatus 20 can also perform the cleaning process of the screen mask M in parallel with the printing process, the time required for the entire printing process can be further shortened. Further, since the printing apparatus 20 has a cleaning unit 60 that moves along the moving direction of the substrate S, the cleaning unit 60 moves along the direction orthogonal to the moving direction of the substrate S. It is possible to make it more compact.

Further, in the printing device 20, since the printing device can be dual-laned by adding the second board working unit 40, two single-lane printing devices and a plurality of transfer devices for sorting the boards are provided. The system configuration can be further simplified as compared with the conventional configuration such as combining, which is preferable in terms of space efficiency and cost.

Also in this printing apparatus 20B, since the identification unit of another substrate S can be imaged to prepare for the next printing process during printing of the substrate S, the time required for the printing process can be further shortened. From the viewpoint of simplifying the configuration, it is preferable that the printing apparatus includes one mask working unit.

In the above-described embodiment, the processing unit 50 is provided with the cleaning unit 60, but the present invention is not particularly limited to this, and the cleaning unit 60 may be omitted from the processing unit 50. Also in this printing apparatus, since the identification unit of another substrate S can be imaged to prepare for the next printing process during printing of the substrate S, the time required for the printing process can be further shortened. Further, in the above-described embodiment, the screen mask M is cleaned by the other substrate working unit during the printing process by one substrate working unit, but this parallel processing may not be performed.

In the above-described embodiment, the first substrate working unit 30 is provided with the suction unit 33 and the second substrate working unit 4 is provided with the suction unit 43, but the screen mask M and the substrate working unit can be closely fixed to each other. If so, the present invention is not particularly limited to this, and for example, a clamp mechanism may be used. Alternatively, the suction units 33 and 43 may be omitted. If the processing unit 50 does not include the cleaning unit 60, the printing apparatus can easily omit the suction units 33 and 43.

In the above-described embodiment, the cleaning unit 60 moves in the moving direction (X-axis direction) of the substrate S to clean the screen mask M, but the present invention is not particularly limited to this, and is orthogonal to the moving direction of the substrate S. The screen mask M may be cleaned by moving in the direction of cleaning. Also in this printing apparatus, since the identification unit of another substrate S can be imaged to prepare for the next printing process during printing of the substrate S, the time required for the printing process can be further shortened.

In the above-described embodiment, the present invention has been described as the printing apparatus 20, but for example, a printing method or a program in which a computer executes the above-described processing may be used. In this printing method, various aspects of the above-mentioned printing apparatus may be adopted, or steps may be added to realize each function of the above-mentioned printing apparatus.
