The mask working unit 26 includes a frame body on which the screen mask M is fixed with a predetermined tension, and a position adjustment unit that adjusts the position of the frame body in the XY directions. The screen mask M is a thin metal plate on which a desired wiring pattern is formed, for example. The substrate working unit 27 is a unit that is disposed below the mask working unit 26, carries in the substrate S, and positions and supports the loaded substrate S. The substrate working unit 27 is a unit for moving the substrate S and the screen mask M in contact with and separating from each other by moving up and down. The substrate working unit 27 includes a transport conveyor 28 that transports the substrate, a support member that supports the substrate from below, and a lifting unit that lifts and lowers the entire substrate working unit 27.

  The holder 30 is where the cartridge 50 is disposed. The printing apparatus 20 includes two holders 30 on the left and right sides of the apparatus, the holder 30 for placing the next cartridge 50 and the holder 30 for placing the cartridge 50 currently in use (see FIG. 1). As shown in FIG. 3, the holder 30 includes a support portion 31 having an opening 32 through which the main body 51 of the cartridge 50 can pass, and a flange portion 52 of the cartridge 50 formed in the support portion 31 to engage the cartridge 30.

The engaging portion 33 is a recess formed at the opening edge of the support portion 31 and into which the portion on the lower surface side of the flange portion 52 is fitted. When the flange portion 52 is fitted to the engaging portion 33, the cartridge 50 is restricted from moving in the XY directions by its own weight. Further, when the cartridge 50 is moved upward and the flange portion 52 is disengaged from the engaging portion 33 (also referred to as a removal position), the movement restriction in the XY direction is released and the cartridge 50 can be removed from the opening portion 32. Become. The operator opens the opening / closing covers 34 (see FIG. 2) provided on the left and right sides of the printing apparatus 20 and places the cartridge 50 in the holder 30.

  The supply exchange device 40 is a device that supplies the solder contained in the cartridge 50 onto the screen mask M. The supply / exchange device 40 also performs processing for automatically exchanging the cartridge 50. The supply exchange device 40 includes a supply head 41 and a supply moving unit 46. The supply head 41 positions and holds the cartridge 50 and discharges the solder. The supply moving unit 46 moves the supply head 41 in the X-axis direction (left-right direction). As shown in FIG. 5 and the like, the supply head 41 includes an air supply unit 42, a clamp unit 43, a rotation motor 44, and a remaining amount sensor 45. Further, as shown in FIG. 3, the supply head 41 includes a back plate portion 41a disposed in the supply moving portion 46, and a fixing member 41b formed to protrude forward from the upper end of the back plate portion 41a. Yes. The supply head 41 is provided with an air supply part 42 and a clamp part 43. The supply head 41 moves between the solder discharge position on the screen mask M and the holder 30 in which the replacement cartridge 50 is disposed. The air supply unit 42 is connected to the cartridge 50 and supplies air for discharging the solder from the cartridge 50 to the cartridge 50. The air supply part 42 has a cylindrical shape and is inserted into a hole-like connection part 56 (see FIG. 3) formed in the cartridge 50. Since the position of the cartridge 50 is fixed by being inserted into the connection portion 56, the air supply portion 42 also serves as a positioning portion for the cartridge 50. This air supply part 42 has an opening below and is disposed on the lower surface of the fixing member 41b. The air supply unit 42 is connected to a pipe 38 (FIG. 4), and discharges air from the opening through the pipe.

  The clamp portion 43 is a member that fixes the cartridge 50. The clamp portion 43 supports and fixes the cartridge 50 from below in a state where the air supply portion 42 is connected to the connection portion 56 of the cartridge 50. The clamp part 43 is formed in a hollow disk shape, and the bottom part of the cartridge 50 is fitted in the hollow part. The clamp portion 43 moves between a fixing position where the cartridge 50 is fixed and a release position where the fixing of the cartridge 50 is released. This clamp part 43 is pivotally supported by the lower side of the back-plate part 41a so that rotation is possible. The clamp portion 43 is in the release position in the same vertical state as the formation direction of the back plate portion 41a, and is in the fixed position in the horizontal state orthogonal to the formation direction of the back plate portion 41a. In the supply exchange device 40, the air supply unit 42 is disposed on the supply head 41 so as to connect to the upper surface (one end side) of the cartridge 50, and the clamp head 43 contacts the lower surface (the other end side) of the cartridge 50. 41. In the supply head 41, when the clamp portion 43 is pivotally moved to the fixed position in the holder 30, the clamp portion 43 pushes up the cartridge 50 and positions the cartridge 50 at the removal position of the holder 30. That is, the fixing operation of the cartridge 50 by the clamp portion 43 also serves as the release operation of the movement restriction of the cartridge 50 from the holder 30.

  The rotation motor 44 rotates the clamp portion 43 between the release position and the fixed position. The remaining amount sensor 45 is a detection unit that detects the amount of solder contained in the cartridge 50. The remaining amount sensor 45 detects the amount of solder by detecting the position of the container 53 containing the solder. The remaining amount sensor 45 may optically detect the position of the storage container 53 (FIG. 4) such as transmitted light or reflected light, or may detect the position of the storage container 53 by magnetic force or the like. Good. Alternatively, the remaining amount sensor 45 may detect the amount of solder accommodated in the cartridge 50 based on the mass of the cartridge 50.

  The supply moving unit 46 is disposed on the front surface of the print head 23. Therefore, the supply head 41 is moved in the Y-axis direction by the printing movement unit 24 and is moved in the X-axis direction by the supply movement unit 46. The supply moving unit 46 includes a guide 47, a drive motor 48, and a ball screw 49. The guide 47 is a rail-shaped member whose longitudinal direction is the left-right direction, and is disposed on the front surface of the print head 23. The drive motor 48 is a motor that rotates the ball screw 49. The supply head 41 moves in the left-right direction along the guide 47 as the ball of the ball screw 49 moves.

  The cartridge 50 has a cylindrical main body 51 and a flange 52 formed with a larger diameter than the main body 51. As illustrated in FIG. 4, the cartridge 50 includes a storage container 53, a lid member 54, a nozzle 55, and a connection portion 56. The storage container 53 is a cup-shaped container in which solder is stored and one end thereof is opened. The container 53 is distributed in a state where a lid (not shown) is attached. In the cartridge 50, the distribution container 53 is directly attached to the main body 51, so that there is no need to move the solder to another container. The lid member 54 is a member that is inserted into the opening of the storage container 53 and inserted. In the center of the lid member 54, a nozzle 55 for discharging the solder to the outside is formed. The connection part 56 is a hole into which the air supply part 42 is inserted and connected, and is formed at the center of the flange part 52. An air supply part 42 is inserted into the connection part 56, and air is supplied into the main body part 51 via the pipe 38. The cartridge 50 discharges the solder from the nozzle 55 by relatively moving the container 53 and the lid member 54 with the air supplied from the connection portion 56 and pushing the lid member 54 into the container 53. In the cartridge 50, the storage container 53 constitutes a piston, and when the solder is discharged, the bottom surface of the storage container 53 is pressed by air, and the storage container 53 moves downward. For this reason, in the cartridge 50, the amount of solder used and the remaining amount can be detected according to the position of the container 53.

  Next, a process in which the printing apparatus 20 prints solder on the substrate S while replacing the cartridge 50 will be described. FIG. 6 is a flowchart illustrating an example of a print processing routine executed by the CPU of the control unit 21. 7A and 7B are explanatory diagrams of the operation of mounting the cartridge 50. FIG. 7A shows the state before the cartridge 50 is fixed, FIG. 7B shows the state when the cartridge 50 is fixed, and FIG. It is explanatory drawing of removal.

  The print processing routine is stored in the HDD of the control unit 21 and is executed after the operator instructs the printing apparatus 20 to perform the print processing. When this routine is started, the CPU of the control unit 21 conveys and fixes the substrate S by the substrate working unit 27 (step S100), and the screen mask M and the substrate S are aligned by the mask working unit 26. The position of M is adjusted (step S110). Next, the CPU determines whether or not it is time to supply solder (step S120). When it is time to supply solder, the CPU executes solder supply processing (step S130). Here, it is determined that it is time to supply solder when the solder on the screen mask M falls below a predetermined amount. This determination may be performed by measuring the amount of solder on the screen mask M, or may be performed by an amount estimated based on the number of movements of the squeegee 25. In the solder supply process, the CPU moves the supply head 41 onto the screen mask M, supplies air from the air supply unit 42, and discharges the solder from the cartridge 50 onto the screen mask M.

  After step S130 or when it is not the solder supply timing in step S120, the CPU performs a printing process (step S140). In the printing process, the CPU lowers the squeegee 25 onto the screen mask M and moves the print head 23 in the front-rear direction. Subsequently, the CPU determines whether or not the cartridge 50 needs to be replaced based on the amount of solder detected by the remaining amount sensor 45 (step S150). Here, it is determined that replacement is required when the solder contained in the cartridge 50 falls below a predetermined threshold. When determining that the cartridge 50 needs to be replaced, the CPU places the cartridge 50 in the empty holder 30 (step S160), and mounts the cartridge 50 placed in the replacement holder 30 on the supply head 41 (step S170). ).

  In releasing the mounting of the cartridge 50, the CPU first moves the supply head 41 to the empty holder 30 and rotates the clamp portion 43 to the release position with the main body portion 51 inserted into the opening portion 32. Then, with the rotation of the clamp portion 43, the cartridge 50 is lowered, and the cartridge 50 is supported by the support portion 31 with the flange portion 52 fitted in the engagement portion 33. Further, when the new cartridge 50 is mounted, the CPU moves the supply head 41 to the holder 30 in which the new cartridge 50 is arranged (FIG. 7A). Next, the clamp part 43 is rotated to the fixed position (FIG. 7B). In the supply head 41, when the clamp portion 43 is positioned at the fixed position, the clamp portion 43 pushes up the cartridge 50 to release the engagement between the flange portion 52 and the engagement portion 33, thereby positioning the cartridge 50 at the removal position. . At this time, in the supply head 41, the air supply part 42 is inserted into the connection part 56, the cartridge 50 is positioned, and air can be supplied to the main body part 51. Then, the CPU moves the supply head 41 so that the main body 51 passes through the opening 32 (FIG. 7C). As described above, since the printing apparatus 20 automatically replaces the cartridge 50, for example, when the operator replaces the cartridge 50, there is no waiting time for replacement of the cartridge 50, and the printing process can be executed continuously. . Further, since the worker only needs to place a new cartridge 50 in the holder 30 when time is available, the degree of freedom of work increases.

  After step S170 or when it is not necessary to replace the cartridge 50 in step S150, the CPU determines whether the production is completed (step S180). When the production is not completed, the CPU executes the processes after step S100, and when the production is completed, the routine is finished as it is.

  Here, the correspondence between the components of the present embodiment and the components of the present invention will be clarified. The air supply part 42 of this embodiment corresponds to the air supply part of the present invention, the clamp part 43 corresponds to the clamp part, the supply head 41 corresponds to the supply head, and the solder paste corresponds to the viscous fluid.

  In the supply exchange device 40 of the embodiment described above, the supply head 41 moves to the holder 30 in which the replacement cartridge 50 is arranged, and the new cartridge 50 is fixed by the clamp portion 43, so that the new cartridge 50 is obtained. Can be exchanged. For this reason, this apparatus can further reduce the work performed by the operator. Further, the cartridge 50 can discharge solder from the cartridge 50 relatively easily by supplying air from the air supply unit 42 to the main body 51. Further, since the air supply unit 42 also serves as a positioning unit for the cartridge 50, a separate member for positioning the cartridge is not required, so that the configuration can be simplified. Furthermore, in the supply / exchange device 40, since the solder can be supplied using the storage container 53 in which the solder is stored as it is, for example, the replacement work of the solder from the storage container to the cartridge can be omitted. .

  Further, in the supply / exchange device 40, when the clamp portion 43 is located at the fixed position in the holder 30, the cartridge 50 is located at a removal position where the holder 30 can be removed. In this apparatus, since the cartridge 50 of the holder 30 can be removed from the movement-restricted state by the movement of the clamp portion 43, the cartridge can be replaced relatively easily. Further, in the supply / exchange device 40, the cartridge 50 can be removed by pushing up the cartridge from the holder by the rotation of the clamp portion 43, and the air can be supplied to the cartridge 50. Therefore, the cartridge 50 can be moved relatively easily. And solder can be supplied. Furthermore, since the supply / exchange device 40 is sandwiched from above and below by the fixing member 41b formed with the air supply portion 42 and the clamp portion 43 to fix the cartridge 50, the cartridge 50 can be supported more reliably. In the supply / exchange device 40, the cartridge can be replaced at a more appropriate replacement timing by detecting the amount of solder by the remaining amount sensor 45.

  It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that the present invention can be implemented in various modes as long as it belongs to the technical scope of the present invention.

  For example, in the above-described embodiment, the air supply unit 42 also serves as a cartridge positioning unit. However, the air supply unit 42 is not particularly limited thereto, and a cartridge 50 positioning member may be provided. Even in this apparatus, the work performed by the operator can be further reduced.

  In the above-described embodiment, the clamp unit 43 is pivotally supported and rotated between the fixed position and the release position. However, the clamp unit 43 moves between the fixed position and the release position. If it does, it will not be limited to this in particular. For example, the clamp unit may be configured to be movable up and down in a horizontal state, and the position of the clamp unit that sandwiches the cartridge 50 may be a fixed position, and the position that does not sandwich the cartridge 50 may be a release position. In the above-described embodiment, the cartridge 50 is sandwiched and supported from the up and down direction. However, the present invention is not limited to this, and the cartridge 50 may be sandwiched and supported from the left and right direction. Furthermore, although the air supply unit 42 is inserted into the upper surface of the cartridge 50, it may be inserted into any surface such as the lower surface or the side surface of the cartridge 50. In the above-described embodiment, the air supply part 42 is formed so as to protrude and is inserted into the hole-like connection part 56 formed in the cartridge 50. However, the air supply part 42 is formed in a hole shape. The connecting portion 56 of the cartridge 50 may be formed to protrude.

  In the above-described embodiment, the cartridge 50 is formed with the flange portion 52, and the holder 30 is formed with the concave engaging portion 33. However, the present invention is not particularly limited thereto, and the flange portion 52 and the engaging portion are formed. 33 may be omitted. Even in this apparatus, the work performed by the operator can be further reduced.

  In the embodiment described above, the supply head 41 is provided with the remaining amount sensor 45, but is not particularly limited thereto, and the remaining amount sensor 45 may be omitted. In this apparatus, for example, the replacement timing of the cartridge 50 may be obtained based on the number of times the solder is supplied.

  In the embodiment described above, the printing apparatus 20 has been described as including the holder 30, but is not particularly limited thereto, and the holder 30 may be included in an external device of the printing apparatus 20. FIG. 8 is a configuration diagram illustrating an example of a schematic configuration of another printing apparatus 20B. The printing apparatus 20 </ b> B does not include the holder 30, and a plurality of holders 30 are disposed on the front surface of the movable exchange cart 70. The supply head 41 places the cartridge 50 in the holder 30 of the exchange cart 70 and mounts the cartridge 50 from the holder 30 of the exchange cart 70. Even in this apparatus, the work performed by the operator can be further reduced.

  In the above-described embodiment, the cartridge 50 includes the storage container 53 and the lid member 54 inserted into the storage container 53. However, if the viscous fluid is supplied by supplying air, this structure is particularly preferable. It is not limited to. In consideration of the fact that refilling work is not required, the cartridge 50 preferably has a structure in which the circulating storage container 53 is used as it is.

  In the embodiment described above, the supply / exchange device 40 has been described as supplying solder by supplying air from the air supply unit 42 to the cartridge 50, but may be a supply / exchange device described below, for example. FIG. 9 is an explanatory diagram of another supply exchange device 40C and a cartridge 50C. In the supply exchange device 40C, the same reference numerals are given to the same components as those in the supply exchange device 40, and the description thereof is omitted. The supply exchange device 40C includes a supply head 41C, a pressure supply unit 42C, and a clamp unit 43C. The supply head 41C is provided with a pressure supply part 42C and a clamp part 43C. The supply head 41C is moved between the discharge position of the viscous fluid 80 such as solder and the holder 30 in which the replacement cartridge 50C is disposed by the supply moving unit 46, for example. The pressure supply unit 42C is connected to the cartridge 50C and applies a vertical pressure to the viscous fluid to discharge the viscous fluid 80 from the cartridge 50C. The pressure supply unit 42C includes a columnar pressing member 142 that presses the lid member 54 that is inserted from the upper opening of the cartridge 50C and disposed on the viscous fluid 80, and an actuator (not shown) that moves the pressing member 142 up and down. Prepare. The clamp portion 43C removes the cartridge 50C from the holder 30 in which the replacement cartridge 50C is disposed, and supports the cartridge 50C from below at a predetermined fixing position (see FIG. 9), thereby fixing the cartridge 50C to the supply head 41C. Is. The clamp portion 43C is substantially the same as the clamp portion 43 except that the cartridge 50C is fixed. As shown in FIG. 9, the cartridge 50 </ b> C is a storage container 53 </ b> C in which a bottomed cylindrical main body 51 </ b> C that contains a viscous fluid 80 and a flange 52 </ b> C formed with a larger diameter than the main body 51 </ b> C are formed. is there. The main body 51C contains a viscous fluid 80, and a discharge hole 55C for discharging the viscous fluid 80 is formed on the bottom surface thereof. The container 53C is distributed in the market with a lid (not shown) attached to the upper opening and a seal or the like attached to the discharge hole 55C. The cartridge 50C discharges the viscous fluid 80 from the discharge hole 55 by inserting the disk-shaped lid member 54C and inserting the pressing member 142 from the upper opening. In this supply exchange device 40C, the usage amount and remaining amount of the viscous fluid 80 can be detected in accordance with the position of the pressing member 142.
