Description

Technical Field

[0001] This invention relates to a printing apparatus, and more particularly to a printing apparatus for printing a coating material from a mask onto a substrate using a squeegee. Background Technology

[0002] Previously, printing apparatuses were known to print coating material from a mask onto a substrate using a squeegee. Such printing apparatuses are disclosed, for example, in International Publication No. 2018 / 105016.

[0003] International Publication No. 2018 / 105016 discloses a printing apparatus for printing solder on a screen mask onto a substrate using a squeegee. A squeegee for storage and replacement and a screen mask storage device are disposed in front of this printing apparatus. The printing apparatus moves the squeegee into the storage device and moves a replacement squeegee into the storage device, thereby changing the squeegee. Similarly, the printing apparatus changes the screen mask by moving the screen mask into the storage device and moving a replacement screen mask into the storage device. In this printing apparatus, the squeegee and the screen mask are moved in and out respectively.

[0006] Patent Document 1: International Publication No. 2018 / 105016 Summary of the Invention

[0007] The problem that the invention aims to solve

[0008] However, in the printing apparatus described in International Publication No. 2018 / 105016, because the squeegee and screen mask are loaded and unloaded separately, preparation time is required for separate replacement of the squeegee and screen mask. In this case, there is a problem of increased preparation time.

[0009] The present invention was made to solve the problems mentioned above, and one object of the present invention is to provide a printing apparatus that can effectively reduce preparation time.

[0010] Technical solutions for solving the problem

[0011] A printing apparatus according to one aspect of the present invention comprises: a squeegee for printing coating material on a substrate from a mask; a moving mechanism for moving the squeegee and the mask simultaneously; and a control unit for controlling the moving mechanism to simultaneously move the squeegee and the mask in or out.

[0012] In one aspect of the printing apparatus of the present invention, as described above, a moving mechanism is provided that moves the squeegee and the mask simultaneously, and a control unit is provided that controls the moving mechanism to simultaneously load or unload the squeegee and the mask. Thus, unlike the case where the squeegee and the mask are prepared separately, the squeegee and the mask can be prepared (replaced) simultaneously, thereby effectively reducing preparation time.

[0013] In the printing apparatus described above, preferably, a mounting member is further included, which is mounted on the mask and used for mounting the squeegee. The moving mechanism is configured to simultaneously load the squeegee and the mask by moving the mask on which the mounting member with the squeegee is mounted. With this configuration, the squeegee and the mask can be simultaneously loaded using the moving mechanism simply by mounting the mounting member on the mask, thus achieving a structure that allows for the simultaneous loading of the squeegee and the mask with a simple structure.

[0014] In this case, preferably, the moving mechanism is configured to simultaneously remove the scraper and the mask by moving the mask while the scraper is positioned on the mask or the mounting member. With this configuration, the scraper and the mask can be simultaneously removed by the moving mechanism simply by positioning the scraper on the mask or the mounting member, thus achieving a simple structure for simultaneously removing the scraper and the mask. Furthermore, since the scraper is removed while positioned on the mask or the mounting member, the used scraper and mask with coating material attached can be processed together. As a result, the workability of cleaning the used scraper and mask with coating material attached can be improved. Additionally, when the scraper is removed while positioned on the mask, since the mask is originally a component that needs cleaning, the number of components that need cleaning can be reduced.

[0015] In the aforementioned printing apparatus with a configuration member, preferably, a frame is provided on the mask, and the configuration member is configured to be mounted on the frame. With this configuration, the frame of the mask can be effectively utilized to mount the configuration member onto the mask, thus enabling a structure that mounts the configuration member onto the mask while suppressing an increase in the number of elements.

[0016] In this case, preferably, the mounting component includes: a fitting portion that fits into the frame; and a tray portion disposed on the side opposite to the frame relative to the fitting portion, and for mounting the scraper. With this configuration, the mounting component can be easily installed onto the frame via the fitting portion. Furthermore, by positioning the tray portion on the side opposite to the frame relative to the fitting portion, the tray portion can be positioned on the outside of the frame (the outside of the mask), thus preventing the tray portion from becoming an obstacle to the printing of the coating material on the mask.

[0017] In the above-described configuration member comprising a fitting portion and a tray portion, preferably, the fitting portion is composed of a recess, and the tray portion is composed of a recess that is recessed to the side opposite to the fitting portion. If configured in this way, the configuration member comprising the fitting portion and the tray portion can be realized with a simpler structure.

[0018] In the aforementioned printing apparatus with a configuration member, it is preferable that the configuration member has a marking portion for confirming the center position of the configuration member. If configured in this way, when the configuration member is mounted on the mask, the marking portion allows for easy and accurate alignment of the mask and the configuration member.

[0019] In the aforementioned printing apparatus with a configuration member, preferably, the configuration member includes a positioning part that positions the squeegee on the configuration member along its length. With this configuration, the squeegee can be moved in while the positioning part positions the squeegee on the configuration member along its length, thus allowing for easy and reliable replacement of the moved-in squeegee.

[0020] In the printing apparatus described above, preferably, a squeegee head is further provided, which is capable of detaching and attaching a squeegee. The squeegee head includes a clamping mechanism that clamps the squeegee along its length. The control unit is configured to control the clamping mechanism by clamping or releasing the squeegee. With this configuration, the detachment and attachment of the squeegee to the squeegee head can be performed automatically under the control of the control unit, thus saving the operator's labor and time required for squeegee preparation. Furthermore, when the clamping mechanism is designed such that the squeegee is clamped along its length and rotated about a rotation axis extending along its length, the squeegee can be clamped in a manner that minimizes the influence of squeegee rotation.

[0021] In this case, preferably, the scraper head further includes a detection unit that detects whether the scraper is installed on the scraper head. If configured this way, the installation and removal of the scraper from the scraper head can be reliably detected. Furthermore, it can reliably detect errors such as when the scraper is not installed on the scraper head despite the clamping mechanism being used to engage it, and when the scraper head remains in a state where the scraper is installed despite the clamping mechanism being used to release the scraper from its gripping position.

[0022] In the printing apparatus described above, preferably, a storage section is further provided, which is capable of storing multiple masks. The control section is configured to control the moving mechanism to simultaneously move the squeegee and the mask into the storage section, and to simultaneously move the squeegee and the mask out of the storage section. With this configuration, when performing the replacement operation of moving the used squeegee and mask to the storage section and moving the intended squeegee and mask into the storage section, the replacement operation can be performed while effectively reducing preparation time.

[0024] According to the present invention, as described above, it is possible to provide a printing apparatus that can effectively reduce preparation time. Attached Figure Description

[0042] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0043] Reference Figures 1 to 14 The structure of a printing apparatus 1 according to one embodiment of the present invention will be described. For example... Figure 1 As shown, the printing apparatus 1 transports the substrate B in the X1 direction via a pair of conveyors 12 (see reference). Figure 2 Solder S is printed onto substrate B at the printing location (refer to...). Figure 6 The apparatus comprises a substrate B, which is a printed circuit board for mounting components (electronic components). Solder S is a bonding material used to bond components onto the substrate B. In the following description, the conveying direction (X1 direction) and its opposite direction (X2 direction) of the substrate B based on a pair of conveyors 12 (belt conveyors) are defined as the X direction, and the direction substantially orthogonal to the X direction in the horizontal plane is defined as the Y direction. The direction substantially orthogonal to both the X and Y directions is defined as the Z direction (vertical direction). Furthermore, solder S is an example of the "coating material" claimed in the claims.

[0044] The printing apparatus 1 is configured such that a substrate B is fed in using an infeed conveyor 1a, a printing pattern Pa formed on a mask M is used to print on the surface of the fed substrate B, and then the printed substrate B is removed using an outfeed conveyor 1b. Here, the mask M has a rectangular flat plate shape when viewed from above (from the Z1 direction). The mask M has multiple openings P1 for forming the printing pattern Pa and non-opening areas P2 that are areas other than the multiple openings P1. Furthermore, a frame F is mounted on the outer periphery of the mask M. Additionally, in… Figures 1-3 The diagram illustrates the state in which the mask M is moved from the work position W for performing a printing operation based on the mask M to the mask changing unit 7, which will be described later.

[0045] like Figure 2 As shown, the printing apparatus 1 includes a base 2, a printing worktable unit 3, a camera unit 4, a mask clamping component 5, a squeegee unit 6, a mask changing unit 7, a detection sensor 8, and a control device 9 (see reference). Figure 5 Furthermore, the control device 9 is an example of the "control unit" in the claim. Additionally, the mask changing unit 7 is an example of the "receiving unit" in the claim.

[0046] The printing stage unit 3 is configured to be mounted on the base 2, hold the substrate B, and align it relative to the mask M. Specifically, the printing stage unit 3 includes an X-axis movement mechanism (not shown), a Y-axis movement mechanism (not shown), an R-axis movement mechanism (not shown), a Z-axis movement mechanism (not shown), a printing stage 11, and a pair of conveyors 12 (see reference). Figure 1 ).

[0047] The X-axis moving mechanism has an X-axis drive unit 13 (see reference). Figure 5 The printing table 11 is moved in the X direction as a drive source. The Y-axis movement mechanism has a Y-axis drive unit 14 (see reference). Figure 5 The printing table 11 is moved in the Y direction as a drive source. The R-axis moving mechanism has an R-axis drive unit 15 (see reference). Figure 5 The Z-axis movement mechanism uses a Z-axis drive unit 16 as a driving source to rotate the printing table 11 about a rotation axis extending along the Z direction. Figure 5 () serves as the driving source, causing the printing worktable 11 to move in the Z direction.

[0048] The printing worktable 11 includes a worktable body 21, a pair of support brackets 22 mounted on the worktable body 21, a support plate 23 with multiple support pins 23a, and a support plate drive unit 24 for moving the support plate 23 in the Z direction. A conveyor 12 (see reference) is provided on the upper part of each of the pair of support brackets 22. Figure 1The support pin 23a is configured such that the support plate 23 is moved in the Z1 direction (upward) by the support plate drive part 24, thereby supporting the base plate B from below.

[0049] like Figure 1 As shown, a pair of conveyors 12 are arranged extending along the X direction. Furthermore, the pair of conveyors 12 are arranged parallel to each other, spaced apart by a predetermined distance in the Y direction. Additionally, the pair of conveyors 12 are configured such that the Y-direction spacing can be adjusted according to the width of the substrate B being conveyed. Specifically, the pair of conveyors 12 are configured to be driven by a substrate width axis drive unit 12a (see reference). Figure 5 Use this to adjust the spacing (width) in the Y direction.

[0050] like Figure 2 and Figure 3 As shown, camera unit 4 is configured to photograph mask M and substrate B. Specifically, camera unit 4 has a camera X-axis movement mechanism 31, a camera Y-axis movement mechanism 32, and an imaging unit 33, which includes a substrate camera 33a and a mask camera 33b. The camera X-axis movement mechanism 31 has an X-axis motor 31a and a ball screw 31b extending in the X direction. The camera Y-axis movement mechanism 32 has a Y-axis motor 32a and a ball screw 32b extending in the Y direction. The substrate camera 33a is configured to photograph substrate B and identify the relative position of substrate B with respect to the printing table 11. The mask camera 33b is configured to photograph mask M to identify the position of mask M.

[0051] Thus, in the printing apparatus 1, after identifying the relative position of substrate B with respect to mask M using substrate camera 33a and mask camera 33b, the relative position (position and tilt in the horizontal plane) of substrate B with respect to mask M is accurately positioned by the X-axis moving mechanism, Y-axis moving mechanism, and R-axis moving mechanism of the printing stage unit 3. Furthermore, in the printing apparatus 1, with the relative position of substrate B with respect to mask M accurately positioned, substrate B is raised by the Z-axis moving mechanism of the printing stage unit 3 to abut against the lower surface of mask M.

[0052] like Figure 3 As shown, the mask clamping member 5 is configured to hold the mask M in the working position W when the mask M is used to print solder S on the substrate B using the printing pattern Pa. Specifically, the mask clamping member 5 has a first mask holding part 41 that holds the end of the mask M in the X1 direction, a second mask holding part 42 that holds the end of the mask M in the X2 direction, and a pressing part (not shown) provided in the first mask holding part 41 that presses the mask M toward the X2 direction.

[0053] like Figure 2 and Figure 3As shown, the squeegee unit 6 is configured to scrape and move the solder S supplied to the upper surface of the mask M along the upper surface of the mask M by reciprocating in the Y direction. Specifically, the squeegee unit 6 includes a squeegee 51, a squeegee Y-axis drive unit 52 for moving the squeegee 51 in the printing direction (Y direction), a squeegee Z-axis drive unit 53 for moving the squeegee 51 in the vertical direction (Z direction), and a squeegee R-axis drive unit 54 for rotating the squeegee 51 about a rotation axis extending in the X direction (see reference). Figure 5 ).

[0054] The squeegee 51 is formed to extend along the X direction. The squeegee 51 is configured to print solder S supplied to the mask M while applying a specified printing pressure (load) to the mask M. The squeegee Y-axis drive unit 52 has a Y-axis motor 52a and a ball screw 52b extending along the Y direction. The squeegee Z-axis drive unit 53 has a Z-axis motor 53a, a belt 53b, and a ball screw 53c extending along the Z direction.

[0055] like Figure 2 As shown, the scraper unit 6 includes a mask slider 55, which causes the mask M to slide along the Y direction to perform a mask replacement operation. Here, a single mask slider 55 is provided in the scraper unit 6. The mask slider 55 has a sliding portion 55a that can move along the Z direction (vertical direction) and a receiving portion 55b that accommodates the sliding portion 55a. The mask slider 55 is, for example, constructed from an air cylinder, with the sliding portion 55a formed by the rod of the air cylinder and the receiving portion 55b formed by the cylinder body of the air cylinder. Furthermore, the mask slider 55 is an example of the "moving mechanism" of the claim.

[0056] The mask slider 55 is configured to move the scraper 51 in the Y direction via the scraper Y-axis drive unit 52, thereby moving integrally in the Y direction. Furthermore, in the mask slider 55, the sliding portion 55a moves in the Z2 direction (downward direction) protruding from the receiving portion 55b until it can abut against the frame F of the mask M at the working position W in the horizontal direction (Y direction). In the mask slider 55, the sliding portion 55a moves in the Z1 direction (upward direction) so as to be received within the receiving portion 55b until it no longer abuts against the frame F of the mask M at the working position W in the horizontal direction (Y direction).

[0057] Thus, the scraper 51 and the mask slider 55 are integrally disposed in the scraper unit 6. Furthermore, by moving the scraper unit 6, the scraper 51 and the mask slider 55 are configured to move integrally in the Y direction. Moreover, the sliding portion 55a of the mask slider 55 abuts against the frame F of the mask M from the Y1 direction or the Y2 direction, causing the mask M to move in the Y1 direction or the Y2 direction.

[0058] The scraper unit 6 includes a solder scraping unit 56 for scraping solder S from the mask M. The solder scraping unit 56 has a scraping portion 56a that scrapes and holds the solder S from the mask M. The scraping portion 56a is configured to move along the Z-direction (vertical direction) between a lowered position and a raised position. The lowered position is used to scrape the solder S from the mask M or to place the scraped solder S onto the mask M, while the raised position does not scrape the solder S from the mask M. The solder scraping unit 56 is configured to move integrally in the Y-direction by moving the scraper 51 in the Y-direction using the scraper Y-axis drive unit 52. When the scraping portion 56a is in the lowered position, the solder scraping unit 56 moves in the Y2 direction, thereby scraping and holding the solder S from the mask M in the scraping portion 56a. In addition, when the scooping part 56a is in the lowered position, the solder scooping unit 56 moves in the Y1 direction to drop the scooped solder S from the scooping part 56a onto the mask M.

[0059] like Figure 4 and Figure 5 As shown, the mask changing unit 7 is configured to accommodate multiple (two) masks M. Specifically, the mask changing unit 7 includes a first storage section 61, a second storage section 62, and a lifting section 63. The first storage section 61 and the second storage section 62 are each configured to accommodate one mask M. The first storage section 61 and the second storage section 62 are arranged vertically.

[0060] The first storage section 61 is an upper storage section positioned above the second storage section 62.

[0061] The second storage section 62 is a lower storage section disposed below the first storage section 61. The lifting section 63 is configured to move the first storage section 61 and the second storage section 62 in a vertical direction. In the mask changing unit 7, the lifting section 63 is mounted on the base 2. In the mask changing unit 7, the second storage section 62 is mounted on the lifting section 63. In the mask changing unit 7, the first storage section 61 is mounted on the second storage section 62. Thus, the first storage section 61 and the second storage section 62 move up and down together with the lifting section 63. The first storage section 61 and the second storage section 62 are configured to move in the Z direction (vertical direction) between a lowered position and an raised position, wherein the lowered position is used to allow the mask M to enter or exit the first storage section 61, and the raised position is used to allow the mask M to enter or exit the second storage section 62.

[0062] like Figure 2As shown, the detection sensor 8 is configured to detect the state of the mask M spanning the mask clamping member 5 and the mask changing unit 7. The detection sensor 8 is respectively provided in the first storage section 61 and the second storage section 62. Specifically, the detection sensor 8 provided in the first storage section 61 is configured to detect the mask M stopped in a state spanning the mask clamping member 5 and the first storage section 61 when the mask M is moved between the working position W and the first storage section 61. The detection sensor 8 provided in the second storage section 62 is configured to detect the mask M stopped in a state spanning the mask clamping member 5 and the second storage section 62 when the mask M is moved between the working position W and the second storage section 62. The detection sensor 8 is, for example, a transmissive sensor, having a light-emitting section (not shown) that emits light and a light-receiving section (not shown) that receives light emitted from the light-emitting section.

[0063] In addition, such as Figure 5 As shown, the control device 9 includes a main control unit 9a, a storage unit 9b, a drive control unit 9c, an I / O control unit 9d, and a camera control unit 9e. The main control unit 9a includes a CPU (Central Processing Unit). The storage unit 9b includes ROM (Read Only Memory) and RAM (Random Access Memory), storing substrate data G1, machine data G2, and a printing program. The main control unit 9a has the function of controlling each part of the printing apparatus 1 based on the printing program stored in the storage unit 9b. Here, the substrate data G1 includes information about the type of substrate B, the size of substrate B, the information about the mask M corresponding to the type of substrate B, and the number of prints for each type of substrate B. The machine data G2 includes information about the Y-direction movement limit position of the squeegee unit 6 and the respective X-direction and Y-direction movement limit positions of the camera unit 4.

[0064] The main control unit 9a is configured to control the scraper unit 6 via the drive control unit 9c. Specifically, the drive control unit 9c controls the drive of the scraper Y-axis drive unit 52, the scraper Z-axis drive unit 53, and the scraper R-axis drive unit 54, thereby causing the scraper 51 to move in the Y and Z directions and to rotate the scraper 51 about a rotation axis extending in the X direction.

[0065] The main control unit 9a is configured to control the printing worktable unit 3 via the drive control unit 9c. Specifically, the main control unit 9a drives the X-axis drive unit 13, Y-axis drive unit 14, R-axis drive unit 15, and Z-axis drive unit 16 via the drive control unit 9c, thereby moving the substrate B in the X, Y, and Z directions and rotating the substrate B about a rotation axis extending in the Z direction. Additionally, the main control unit 9a drives the support plate drive unit 24 via the drive control unit 9c, causing the support plate 23 to move, thereby moving the support pin 23a in the Z direction (vertical direction). Furthermore, the main control unit 9a drives the substrate width axis drive unit 12a via the drive control unit 9c, thereby adjusting the Y-direction spacing (width) of the pair of conveyors 12. Finally, the main control unit 9a drives the substrate transport axis drive unit 17 via the drive control unit 9c, causing the substrate B to be transported in the X direction.

[0066] The main control unit 9a is configured to control the camera unit 4 via the drive control unit 9c. Specifically, the main control unit 9a drives the camera X-axis movement mechanism 31 and the camera Y-axis movement mechanism 32 via the drive control unit 9c, so that the camera unit 33 (the substrate camera 33a and the mask camera 33b) moves in the X and Y directions.

[0067] The main control unit 9a is configured to control the camera unit 4 via the camera control unit 9e. Specifically, the main control unit 9a controls the image capture operation of the substrate camera 33a on the substrate B via the camera control unit 9e. The main control unit 9a also controls the image capture operation of the mask camera 33b on the mask M via the camera control unit 9e.

[0068] Furthermore, the main control unit 9a is configured to control the scraper unit 6 via the IO control unit 9d. Specifically, the main control unit 9a controls the lifting and lowering movement of the sliding portion 55a of the mask slider 55 via the IO control unit 9d.

[0069] Furthermore, the main control unit 9a is configured to control the mask changing unit 7 via the IO control unit 9d. Specifically, the main control unit 9a controls the lifting and lowering operation of the lifting unit 63 on the first storage section 61 and the second storage section 62 of the mask changing unit 7 via the IO control unit 9d. Additionally, the main control unit 9a is configured to receive, via the IO control unit 9d, the detection signal from the detection sensor 8 when a mask M is stopped while straddling the mask clamping member 5 and the first storage section 61.

[0070] (Replacement of scraper and mask)

[0071] In this embodiment, as Figure 6As shown, the mask slider 55 is configured to move the scraper 51 and the mask M simultaneously. Furthermore, the control device 9 is configured to control the mask slider 55 to simultaneously move the scraper 51 and the mask M in or out. Specifically, the control device 9 is configured to control the mask slider 55 to simultaneously move the scraper 51 and the mask M from the mask changing unit 7 to the working position W, and to simultaneously move the scraper 51 and the mask M out from the working position W to the mask changing unit 7. For example, when changing the production type of substrate B, the control device 9 is configured to simultaneously move the used scraper 51 and mask M corresponding to the current production type of substrate B to the mask changing unit 7, and simultaneously move the planned scraper 51 and mask M corresponding to the next production type of substrate B into the mask changing unit 7, thereby controlling the replacement of the scraper 51 and mask M.

[0072] In this embodiment, a configuration member 90 is provided in the printing apparatus 1. The configuration member 90 is mounted on the mask M and is configured for placement by the squeegee 51. The configuration member 90 is configured to be mounted on the mask M by a user. The mask slider 55 is configured such that by moving the mask M on which the configuration member 90 is mounted, the squeegee 51 and the mask M are simultaneously moved in, and the configuration member 90 is placed by the squeegee 51. Furthermore, the mask slider 55 is configured such that, in the state where the squeegee 51 is placed on the mask M or on the configuration member 90 (in... Figure 6 In the state where the mask M is positioned, the mask M is moved, and the scraper 51 and the mask M are removed at the same time.

[0073] like Figure 7 and Figure 8 As shown, the configuration member 90 is configured to be mounted on a rectangular frame F. Specifically, the configuration member 90 is formed to extend along the X direction and is configured as a portion F1 extending along the X direction on the Y1 direction side of the frame F. The configuration member 90 includes: a fitting portion 91, which fits into the frame F; and a tray portion 92, which is disposed opposite to the fitting portion 91 on the side opposite to the frame F (Y1 direction side) and is disposed for the scraper 51. The configuration member 90 is composed of a single plate-shaped member, and the fitting portion 91 and the tray portion 92 are formed by bending the single plate-shaped member constituting the configuration member 90.

[0074] like Figure 8 , Figure 10 and Figure 11As shown, the fitting portion 91 is composed of a recess that is recessed from the Z2 direction side toward the Z1 direction side. The fitting portion 91 is configured to fit into the frame F by moving toward the Z2 direction side. The fitting portion 91 has a pair of side plate portions 91a and 91b extending along the Z direction, and a bottom plate portion 91c extending along the Y direction to connect the pair of side plate portions 91a and 91b. The pair of side plate portions 91a and 91b are respectively disposed on the inner side (Y2 direction side) and outer side (Y1 direction side) of part F1 of the frame F. The inner side surface of the side plate portion 91a abuts against the inner side surface of part F1 of the frame F. The inner side surface of the side plate portion 91b abuts against the outer side surface of part F1 of the frame F. The bottom plate portion 91c is disposed on the upper side (Z1 direction side) of part F1 of the frame F. The lower surface of the bottom plate portion 91c abuts against the upper surface of part F1 of the frame F.

[0075] The tray portion 92 is formed by a recess that is recessed to the side opposite to the fitting portion 91 (Z2 direction side). The tray portion 92 is configured such that the scraper 51 is arranged to move from the Z1 direction side to the Z2 direction side via the scraper 51. The tray portion 92 has a pair of side plate portions 92a and 92b extending in the Z direction, and a bottom plate portion 92c extending in the Y direction to connect the pair of side plate portions 92a and 92b. Furthermore, the side plate portions 92a and 91b are common. The pair of side plate portions 92a and 92b are arranged to sandwich the scraper 51 in the middle. The bottom plate portion 92c supports the scraper 51 via the support portion 95 described later.

[0076] In addition, in this embodiment, such as Figure 7 and Figure 8 As shown, a marking portion 93 is formed on the configuration member 90, which is used to confirm the center position of the configuration member 90. The marking portion 93 is formed as a line extending in the Y direction at the center position of the configuration member 90 in the X direction. The marking portion 93 is formed on the upper surface of the base plate portion 91c of the fitting portion 91. The user can use the marking portion 93 as a marker to align the center position of the configuration member 90 in the X direction with the center position of the mask M in the X direction.

[0077] In addition, such as Figures 7-10As shown, a bracket 94 is provided on the configuration member 90, which is used to fix the configuration member 90 to the frame F. The configuration member 90 is fastened to the frame F by screws 94b via an elongated hole 94a formed in the bracket 94 and a threaded hole 91aa formed in the side plate portion 91a of the fitting portion 91. The elongated hole 94a is formed to extend in the X direction. Thus, when the user aligns the center position of the configuration member 90 in the X direction with the center position of the mask M in the X direction, the configuration member 90 can be moved in the X direction. In addition, two elongated holes 94a are arranged in the vertical direction (Z direction). In addition, when viewed from above (Z1 direction), the bracket 94 is formed in an L-shape. The bent portion of the L-shaped bracket 94 is configured to abut against the portion F2 of the frame F that extends in the Y direction. In addition, the bracket 94 is provided at the end in the X1 direction and the end in the X2 direction of the configuration member 90.

[0078] In addition, such as Figure 8 and Figure 11 As shown, a support portion 95 for supporting the scraper 51 is provided on the configuration member 90. The support portion 95 is a cuboid block member. The support portion 95 is configured such that its upper surface, which serves as a support surface 95a, abuts against the scraper surface 51aa of the body 51a of the scraper 51 from below (Z2 direction side), thereby supporting the scraper 51 from below. In addition, two support portions 95 are provided separately in the X direction on the upper surface of the base plate portion 92c. The two support portions 95 are respectively configured to support the scraper 51 from below on the X1 direction side and the X2 direction side side.

[0079] In this embodiment, the support portion 95 also functions as a positioning portion, which positions the squeegee 51 on the mounting member 90 in the longitudinal direction (X direction) of the squeegee 51. The support portion 95 is configured to position the squeegee 51 on the mounting member 90 in the longitudinal direction by abutting against the lateral leakage prevention member 51b of the squeegee 51. In order to prevent lateral leakage of solder S that moves outward in the X direction from the squeegee surface 51aa during the printing operation, lateral leakage prevention members 51b are provided at the ends of both sides of the main body 51a in the X direction of the squeegee 51.

[0080] The support portion 95 on the X1 direction side is configured such that its outer surface (the surface on the X1 direction side) abuts against the inner surface (the surface on the X2 direction side) of the lateral leakage prevention member 51b of the scraper 51, thereby restricting the movement of the scraper 51 towards the X2 direction side. Similarly, the support portion 95 on the X2 direction side is configured such that its outer surface (the surface on the X2 direction side) abuts against the inner surface (the surface on the X1 direction side) of the lateral leakage prevention member 51b of the scraper 51, thereby restricting the movement of the scraper 51 towards the X2 direction side.

[0081] Furthermore, the support portion 95 is fastened to the base plate portion 92c via a threaded hole 95b formed inside the support portion 95 by screws 95c. The threaded hole 95b is formed on the side opposite to the support surface 95a (the lower side, the Z2 direction side). The support portion 95 is fastened to the base plate portion 92c from the side opposite to the support surface 95a by screws 95c.

[0082] In addition, in this embodiment, such as Figure 12 As shown, the scraper unit 6 includes a scraper head 57 capable of detaching and mounting the scraper 51. The scraper head 57 is provided with an R-axis motor 54a, an R-axis power transmission unit 54b, and an R-axis output unit 54c as a scraper R-axis drive unit 54. The R-axis motor 54a is configured to generate a driving force for rotating the scraper 51 about a rotation axis C extending in the X direction. The R-axis power transmission unit 54b includes multiple gears and is configured to transmit the driving force from the R-axis motor 54a to the R-axis output unit 54c. The R-axis output unit 54c is a scraper mounting part for mounting the scraper 51, and is configured to rotate itself about the rotation axis C via the driving force from the R-axis motor 54a through the R-axis power transmission unit 54b, thereby causing the scraper 51 to rotate about the rotation axis C.

[0083] In addition, in this embodiment, such as Figure 12 and Figure 13 As shown, a clamping mechanism 58 is provided in the R-axis output section 54c of the scraper head 57, which clamps the scraper 51 along the length direction (X direction) of the scraper 51. The control device 9 is configured to control the clamping mechanism 58 by clamping or releasing the scraper 51.

[0084] The clamping mechanism 58 includes a cylinder 58a and a clamping plate 58b. The cylinder 58a is configured to drive the clamping plate 58b in the X direction. The clamping plate 58b is configured to move between an engaged position and an unengaged position by the driving force of the cylinder 58a. The engaged position is a position where it engages with a knob 51c, which serves as the mounting part of the scraper 51, and the unengaged position is a position where it does not engage with the knob 51c.

[0085] The clamping plate 58b is L-shaped, having a first portion 58ba and a second portion 58bb. The first portion 58ba is mounted on the rod 58aa of the cylinder 58a. The second portion 58bb extends inward from the first portion 58ba in the X direction and engages with the knob 51c. Additionally, one clamping mechanism 58 is provided at each end of the R-axis output section 54c in the X1 direction and the X2 direction.

[0086] The knob 51c protrudes from the side opposite to the scraper surface 51aa of the body 51a of the scraper 51 (Z1 direction side) towards the Z1 direction. A neck 51ca is formed in the knob 51c, which serves as an engaging portion for engaging with the second part 58bb of the clamping plate 58b. Furthermore, two knobs 51c are provided separately along the X direction on the body 51a of the scraper 51.

[0087] When the scraper 51 is mounted on the scraper head 57, the scraper head 57 first descends toward the scraper 51 disposed on the mounting member 90 via the scraper Z-axis drive unit 53. Furthermore, the second part 58bb of the clamping plate 58b is aligned with the height of the knob 51c of the scraper 51 (the second part 58bb and the knob 51c are opposite each other in the horizontal direction). In this state, the clamping plate 58b is driven inward in the X direction by the cylinders 58a of the two clamping mechanisms 58. As a result, the two knobs 51c of the scraper 51 are clamped in the X direction by the two clamping plates 58b. Thus, the scraper 51 is mounted on the scraper head 57.

[0088] Furthermore, when the squeegee 51 is removed from the squeegee head 57, firstly, the clamping plate 58b is driven outward in the X direction by the cylinders 58a of the two clamping mechanisms 58. As a result, the clamping of the two clamping plates 58b onto the two knobs 51c of the squeegee 51 is released. Then, the squeegee head 57 rises in a manner separating from the squeegee 51 via the squeegee Z-axis drive unit 53. Thus, the squeegee 51 is removed from the squeegee head 57. At this time, the squeegee 51 is either positioned on the mask M or on the mounting member 90. Moreover, whether the squeegee 51 is positioned on the mask M or on the mounting member 90 is preset in the printing apparatus 1 based on user input.

[0089] In addition, in this embodiment, such as Figure 14 As shown, a detection unit 59 is provided in the R-axis output section 54c of the scraper head 57. This detection unit 59 detects whether the scraper 51 is installed in the scraper head 57. The detection unit 59 is a non-contact sensor, positioned close to the scraper 51 when it is installed in the scraper head 57. The presence of the scraper 51 is detected by the detection unit 59 when it is installed in the scraper head 57, thus detecting the presence of the scraper 51. Conversely, the absence of the scraper 51 is detected by the detection unit 59 when it is not installed in the scraper head 57, thus detecting the absence of the scraper 51. The non-contact sensor used in the detection unit 59 is not particularly limited; for example, an optical non-contact sensor can be used. Furthermore, only one detection unit 59 is provided on the X1 direction side of the R-axis output section 54c of the scraper head 57.

[0090] Furthermore, the detection unit 59 is separate from the detection unit 58ab of the cylinder 58a. The detection unit 58ab of the cylinder 58a is a position sensor for detecting the position of the rod 58aa. By detecting the position of the rod 58aa by the detection unit 58ab, it is possible to detect whether the clamping plate 58b is in a clamped state with the scraper 51 engaged or in a non-clamped state with the scraper 51 disengaged. There are no particular limitations on the position sensor for the detection unit 58ab; for example, a magnetic position sensor can be used.

[0091] (Control processes related to printing)

[0092] Reference Figure 15 The control processes related to printing in the printing apparatus 1 of this embodiment will be described based on the flowchart. Furthermore, each process in the flowchart is executed by the control device 9.

[0093] like Figure 15 As shown, firstly, in step S101, a simultaneous loading process of the scraper 51 and the mask M is performed. Then, in step S102, substrate B is produced (printing operation). Then, in step S103, when the production of substrate B is completed, a simultaneous unloading process of the scraper 51 and the mask M is performed. Finally, the control process ends.

[0094] (Moving in process)

[0095] Next, refer to Figure 16 Based on the flowchart Figure 15 The details of the loading process in step S101 will be explained. Furthermore, each process in the flowchart is executed by the control device 9.

[0096] like Figure 16 As shown, in step S111, the scraper 51 and the mask M are simultaneously moved from the mask changing unit 7 to the working position W via the mask sliding member 55. That is, the mask M, on which the configuration member 90 with the scraper 51 is mounted, is moved by the mask sliding member 55, thereby moving the scraper 51 and the mask M simultaneously.

[0097] Then, in step S112, the mask M is clamped and held in place by the mask clamping member 5. This determines the position of the scraper 51 in the Y direction of the working position W. Furthermore, the positioning member 90 is positioned relative to the mask M in the X direction by the marking part 93, and the scraper 51 is positioned relative to the positioning member 90 in the X direction by the support part 95. Therefore, the position of the scraper 51 in the X direction of the working position W is determined. Thus, the scraper 51 can be positioned correctly, and the position of the scraper 51 does not need to be detected by a sensor before it is installed onto the scraper head 57. Therefore, the scraper 51 can be easily installed onto the scraper head 57.

[0098] Then, in step S113, the scraper head 57 is moved to the clamping position of the clamping scraper 51 by the scraper Y-axis drive unit 52. Furthermore, the clamping position refers to the position above the scraper 51 disposed on the mounting member 90.

[0099] Then, in step S114, the scraper head 57 is lowered toward the scraper 51 disposed on the configuration member 90 by the scraper Z-axis drive unit 53.

[0100] Then, in step S115, the scraper 51 is clamped and secured by the clamping mechanism 58. Thus, the scraper 51 is mounted on the scraper head 57.

[0101] Then, in step S116, the scraper head 57 is raised by the scraper Z-axis drive unit 53.

[0102] Then, in step S117, based on the detection result of the detection unit 59, it is determined whether the scraper 51 is installed on the scraper head 57. If the presence of the scraper 51 is detected by the detection unit 59, it is determined that the scraper 51 is installed on the scraper head 57, and the loading process ends.

[0103] Furthermore, if the presence of the scraper 51 is not detected by the detection unit 59, it is determined that the scraper 51 is not installed on the scraper head 57, and the process proceeds to step S118. Then, in step S118, error stop processing is performed. In error stop processing, the operation of the printing device 1 is stopped, and an error notification is sent to the user.

[0104] (Relocation)

[0105] Next, refer to Figure 17 Based on the flowchart Figure 15 The details of the removal process in step S103 will be explained. Furthermore, each process in the flowchart is executed by the control device 9.

[0106] like Figure 17 As shown, in step S121, the scraper head 57 is moved to a non-clamped position where the scraper 51 is not clamped, by the scraper Y-axis drive unit 52. Furthermore, the non-clamped position refers to a position preset by the user between the position above the mask M and the position above the placement member 90.

[0107] Then, in step S122, the scraper head 57 is lowered toward the non-clamping position by the scraper Z-axis drive unit 53.

[0108] Then, in step S123, the clamping mechanism 58 releases the scraper 51 from the clamp, so that the scraper 51 is not clamped. As a result, the scraper 51 is removed from the scraper head 57.

[0109] Then, in step S124, the scraper head 57 is raised by the scraper Z-axis drive unit 53.

[0110] Then, in step S125, based on the detection result of the detection unit 59, it is determined whether the scraper 51 is not installed on the scraper head 57. If the presence of the scraper 51 is not detected by the detection unit 59, it is determined that the scraper 51 is not installed on the scraper head 57, and the process proceeds to step S126.

[0111] Then, in step S126, the scraper 51 and the mask M are simultaneously moved from the working position W to the mask changing unit 7 via the mask slider 55. That is, the mask M is moved by the mask slider 55 while the scraper 51 is positioned on the mask M or on the mounting member 90, thereby simultaneously moving the scraper 51 and the mask M. Then, the moving process ends. Afterwards, when the next scraper 51 and mask M are replaced, the next scraper 51 and mask M are moved in.

[0112] Furthermore, in step S126, if the presence of the scraper 51 is detected by the detection unit 59, it is determined that the scraper 51 is installed on the scraper head 57, and the process proceeds to step S127. Then, in step S127, error stop processing is performed. In error stop processing, the operation of the printing device 1 is stopped, and an error notification is sent to the user.

[0113] (Effects of this implementation method)

[0114] In this embodiment, the following effect can be obtained.

[0115] In this embodiment, as described above, a mask slider 55 is provided that moves the scraper 51 and the mask M simultaneously, and a control device 9 is provided to control the mask slider 55 in a manner that moves the scraper 51 and the mask M in or out simultaneously. Thus, unlike the case where the scraper 51 and the mask M are prepared separately, the scraper 51 and the mask M can be prepared (replaced) simultaneously, thereby effectively reducing preparation time.

[0116] Furthermore, in this embodiment, as described above, the printing apparatus 1 includes a configuration member 90, which is mounted on the mask M and for the squeegee 51 to be configured. The mask slider 55 is configured such that by moving the mask M, on which the configuration member 90 with the squeegee 51 is mounted, both the squeegee 51 and the mask M are simultaneously moved in. Thus, by simply mounting the configuration member 90 on the mask M, both the squeegee 51 and the mask M can be simultaneously moved in via the mask slider 55, thereby achieving a structure that allows for the simultaneous movement of both the squeegee 51 and the mask M with a simple structure.

[0117] Furthermore, in this embodiment, as described above, the mask slider 55 is configured such that, with the scraper 51 disposed on the mask M or the mounting member 90, moving the mask M simultaneously removes both the scraper 51 and the mask M. Thus, by simply disposing the scraper 51 on the mask M or the mounting member 90, the mask slider 55 can simultaneously remove both the scraper 51 and the mask M, achieving a simple structure for simultaneously removing both the scraper 51 and the mask M. Additionally, since the used scraper 51 with solder S attached is removed while disposed on the mask M or the mounting member 90, both the used scraper 51 with solder S attached and the mask M can be processed together. As a result, the workability of cleaning the used scraper 51 with solder S attached and the mask M can be improved. Furthermore, when the scraper 51 is removed while disposed on the mask M, since the mask M is originally a component that needs cleaning, the number of components that need cleaning can be reduced.

[0118] Furthermore, in this embodiment, as described above, a frame F is provided on the mask M. The configuration member 90 is configured to be mounted on the frame F. Therefore, the frame F of the mask M can be used effectively to mount the configuration member 90 on the mask M, thus enabling a structure in which the configuration member 90 is mounted on the mask M while suppressing an increase in the number of elements.

[0119] Furthermore, in this embodiment, as described above, the configuration member 90 includes: a fitting portion 91 that fits into the frame F; and a tray portion 92 disposed opposite to the frame F relative to the fitting portion 91, and for which the scraper 51 is disposed. Thus, the fitting portion 91 allows for easy mounting of the configuration member 90 onto the frame F. Additionally, by disposing the tray portion 92 opposite to the frame F relative to the fitting portion 91, the tray portion 92 can be disposed on the outside of the frame F (the outside of the mask M), thereby preventing the tray portion 92 from becoming an obstacle to the printing of solder S on the mask M.

[0120] Furthermore, in this embodiment, as described above, the fitting portion 91 is composed of a recess. The tray portion 92 is composed of a recess that is recessed to the side opposite to the fitting portion 91. Therefore, the configuration member 90 including the fitting portion 91 and the tray portion 92 can be implemented with a simpler structure.

[0121] Furthermore, in this embodiment, as described above, a marking portion 93 is formed on the configuration member 90, which is used to confirm the center position of the configuration member 90. Therefore, when the configuration member 90 is mounted on the mask M, the marking portion 93 allows for easy and accurate alignment of the mask M and the configuration member 90.

[0122] Furthermore, in this embodiment, as described above, the configuration member 90 includes a support portion 95 that positions the scraper 51 on the configuration member 90 in the longitudinal direction of the scraper 51. Therefore, the scraper 51 can be moved in while the position of the scraper 51 on the configuration member 90 is positioned in the longitudinal direction of the scraper 51 by the support portion 95, thus enabling easy and reliable replacement of the moved-in scraper 51.

[0123] Furthermore, in this embodiment, as described above, the printing apparatus 1 includes a squeegee head 57 capable of detaching and attaching the squeegee 51. The squeegee head 57 includes a clamping mechanism 58 that clamps the squeegee 51 in the longitudinal direction of the squeegee 51. The control device 9 is configured to control the clamping mechanism 58 in a manner that clamps or releases the squeegee 51. As a result, the detachment and attachment of the squeegee 51 to the squeegee head 57 can be performed automatically under the control of the control device 9, thus saving the labor and time required for preparing the squeegee 51. In addition, when the clamping mechanism 58 clamps the squeegee 51 in the longitudinal direction of the squeegee 51, allowing the squeegee 51 to rotate about a rotation axis C extending in the longitudinal direction of the squeegee 51, the squeegee 51 can be clamped in a manner that minimizes the influence of the rotation of the squeegee 51.

[0124] Furthermore, in this embodiment, as described above, the scraper head 57 includes a detection unit 59 that detects whether the scraper 51 is installed on the scraper head 57. This allows for reliable detection of the attachment and removal of the scraper 51 from the scraper head 57. Additionally, it allows for reliable detection in cases where the scraper 51 is not installed on the scraper head 57 despite the clamping mechanism 58 being used to clamp it in, and in cases where the scraper head 57 remains equipped with the scraper 51 despite the clamping mechanism 58 being used to release the scraper 51 from the clamping position.

[0125] Furthermore, in this embodiment, as described above, the printing apparatus 1 includes a mask changing unit 7 capable of accommodating multiple masks M. The control device 9 is configured to control the mask sliding member 55 in a manner that simultaneously moves the squeegee 51 and the mask M into the mask changing unit 7, and to simultaneously move the squeegee 51 and the mask M out of the mask changing unit 7. Therefore, when performing a changing operation of moving the used squeegee 51 and mask M to the mask changing unit 7 and moving the intended-to-be-used squeegee 51 and mask M into the mask changing unit 7, the changing operation can be performed while effectively reducing preparation time.
