[0027] In the following description, embodiments of the present invention will be described in detail with reference to the accompanying drawings. When describing with reference to the drawings, the same or corresponding constituent elements will be given the same reference numerals, regardless of the drawing numbers, and repeated descriptions thereof will be omitted.

[0028] Figure 1 This is a view used to illustrate a droplet discharging device according to some embodiments of the present invention.

[0029] Figure 2 yes Figure 1 The plan view of the base is shown. Figure 3 yes Figure 1 The bottom view of the component retainer shown. Figure 4 yes Figure 1 A side view of the droplet discharge device.

[0030] Reference Figures 1 to 4 According to some embodiments of the present invention, a droplet discharge device (or discharge module) 1 includes a plurality of heads 10, a base 100, a component retainer 200, guide pins 210a and 210b, guide retainers 110a and 110b, first fastening parts 220a and 220b, and second fastening parts 120a and 120b, etc.

[0031] The base 100 is a component for supporting a plurality of heads 10. For example, the base 100 may have a generally rectangular shape. As shown, the short side of the base 100 may be arranged along a first direction X, and the long side may be arranged along a second direction Y. In addition, the base 100 may have a plate shape.

[0032] A head-fixing region 101 for fixing multiple heads 10 is located near the center of the base 100. The head-fixing region 101 may have, for example, a basic rectangular shape. As shown, the short side of the head-fixing region 101 may be arranged along a first direction X, while its long side may be arranged along a second direction Y. For example, five heads 10 may be fixed in the head-fixing region 101, but it is not limited thereto. Four or fewer heads 10 may also be fixed, or six or more heads 10 may be fixed.

[0033] The component retainer 200 is located above the base 100, and the base 100 and the component retainer 200 are connected to each other. The component retainer 200 includes an opening 201 formed at a position corresponding to the head fixing region 101. When the base 100 and the component retainer 200 are connected to each other, a plurality of heads 10 fixed to the base 100 (i.e., the head fixing region 101) pass through the opening 201 (see [link to relevant documentation]). Figure 4 ).

[0034] Position adjustment members 301 and 302 are disposed on another surface (e.g., the upper surface) of the component retainer 200. Position adjustment members 301 and 302 can move the head component in a first direction X, move in a second direction Y, and / or rotate at an angle (theta rotation).

[0035] Here, in order to connect the base 100 and the component retainer 200, the component retainer 200 is provided with guide pins 210a, 210b and first fastening parts 220a, 220b, and the base 100 is provided with guide retainers 110a, 110b and second fastening parts 120a, 120b.

[0036] Specifically, guide pins 210a and 210b and first fastening portions 220a and 220b protruding toward the base 100 are provided on one surface (e.g., the bottom surface) of the component retainer 200. Guide retainers 110a and 110b protruding toward the component retainer 200 are provided on one surface (e.g., the upper surface) of the base 100 at positions corresponding to the guide pins 210a and 210b, and second fastening portions 120a and 120b are provided at positions corresponding to the first fastening portions 220a and 220b. The guide pins 210a and 210b are fastened to the guide retainers 110a and 110b, and the first fastening portions 220a and 220b are fastened to the second fastening portions 120a and 120b.

[0037] like Figure 2 As shown, the base 100 may be provided with two guide retainers 110a and 110b and two second fastening portions 120a and 120b. For example, compared with the guide retainers 110a and 110b, the second fastening portions 120a and 120b are provided near the edge (i.e., the short side) of the rectangular head fixing region 101.

[0038] Compared to the second fastening portions 120a and 120b, the guide retainers 110a and 110b are positioned near the vertices of the rectangular head fixing region 101. Specifically, as shown, the two guide retainers 110a and 110b can be positioned near two diagonally opposite vertices of the four vertices of the head fixing region 101. Although not shown separately, there can also be four guide retainers, and each of the four guide retainers can be positioned near one of the four vertices of the head fixing region 101.

[0039] like Figure 3 As shown, two guide pins 210a and 210b and two first fastening portions 220a and 220b may be provided on the component retainer 200. For example, compared with the guide pins 210a and 210b, the first fastening portions 220a and 220b are set near the edge (i.e., the short side) of the rectangular opening 201.

[0040] Compared to the first fastening portions 220a and 220b, the guide pins 210a and 210b are positioned near the vertices of the rectangular opening 201. Specifically, as shown in the figure, the two guide pins 210a and 210b can be positioned as two diagonally opposite vertices of the four vertices near the opening 201. Although not shown separately, there can also be four guide pins, and each of the four guide pins can be positioned near the four vertices of the opening 201 respectively.

[0041] Alternatively, the guide retainers 110a and 110b can be pressure latches equipped with release buttons 115a and 115b. Guide pins 210a and 210b are secured to holes inside the pressure latch. The user can separate the guide pins 210a and 210b from the pressure latch by pressing the release buttons 115a and 115b. (See below for further details.) Figure 5 and Figure 6 Describes the connection / disconnection between guide pins 210a, 210b and the pressure latch. Before the first fasteners 220a, 220b and the second fasteners 120a, 120b are fastened, the fastening between guide retainers 110a, 110b and guide pins 210a, 210b can be performed to determine the position of the base 100 and the component retainer 200. As shown, release buttons 115a, 115b are positioned exposed on the bottom surface of the base 100. Therefore, the operator can easily press the exposed release buttons 115a, 115b to disengage the guide pins 210a, 210b from the pressure latch.

[0042] Furthermore, the base 100 and the component retainer 200 are securely connected to each other via first fastening portions 220a and 220b and second fastening portions 120a and 120b. The first fastening portions 220a and 220b are fastened to the second fastening portions 120a and 120b by supplying locking air to either the first fastening portions 220a and 220b or the second fastening portions 120a and 120b. The accompanying drawings show the first fastening portions 220a and 220b as pneumatic clamps receiving locking air, and the second fastening portions 120a and 120b as clamping blocks fastened to the pneumatic clamps, but this is not a limitation. That is, the second fastening portions 120a and 120b could also be pneumatic clamps, and the first fastening portions 220a and 220b could be clamping blocks. The following description will be based on the case where the first fastening parts 220a and 220b are pneumatic clamps and the second fastening parts 120a and 120b are clamping blocks.

[0043] In traditional inkjet equipment, the U-shaped base, which surrounds multiple heads, transfers heat to the heads through the base. Furthermore, convective heat is trapped in the space between the base and the heads, preventing it from dissipating. This heat can potentially disrupt head alignment.

[0044] However, in the droplet discharge device (or discharge module) 1 according to some embodiments of the present invention, since the base does not surround the periphery of the plurality of heads 10, heat cannot be effectively transferred from the base to the heads. Furthermore, convective heat can be easily released to the periphery. Therefore, misalignment of the plurality of heads can be reduced.

[0045] Figure 5 and Figure 6 It is used for explanation Figure 1 A view showing the fastening operation of the guide pin and guide retainer.

[0046] First, refer to Figure 5 Guide pin 210a is disposed on component retainer 200, and guide retainer 110a is disposed on base 100.

[0047] The guide retainer 110a is a pressure latch and includes a retainer body 114a fixed to the base 100, a hole 117a disposed at the tip region of the retainer body 114a, a ball 118a disposed on the side wall (inner peripheral surface) of the hole 117a, a rod 116a disposed within the retainer body 114a, and a release button 115a connected to the rod 116a.

[0048] Align the guide pin 210a and guide retainer 110a, and bring the component retainer 200 and base 100 close to each other. Figure 5The illustration shows the base 100 moving toward the component retainer 200, but is not limited to this.

[0049] like Figure 6 As shown, the guide pin 210a is inserted into the hole 117a of the guide retainer 110a and is fixed by the ball 118a provided on the inner circumferential surface of the hole 117a.

[0050] Figure 7 and Figure 8 It is used for explanation Figure 1 A view showing the fastening operation of the first and second fastening parts.

[0051] First, refer to Figure 7 The first fastening part 220a is provided on the component retainer 200, and the second fastening part 120a is provided on the base 100. The first fastening part 220a may be a pneumatic clamp, and the second fastening part 120a may be a clamping block.

[0052] The first fastening part 220a includes a main body 228a, a piston rod 229a, a spring 226a, a locking port 221a, and a release port 222a.

[0053] The main body 228a has a hole 224a formed on one side thereon. A piston rod 229a is disposed in the main body 228a and includes a support region 2291 and a rod region 2292, the rod region 2292 connecting to the support region 2291 and passing through the hole 224a. A groove 2293 is formed in the rod region 2292. A steel ball 225a is disposed on the main body 228a (i.e., near the hole 224a), the position of which can be changed according to the position of the piston rod 229a. A spring 226a is disposed in the main body 228a and is disposed between the inner wall of the main body 228a and the support region 2291. A locking port 221a is disposed on the main body 228a and is used to provide locking air to the support region 2291. Furthermore, a release port 222a is disposed on the main body 228a and is used to provide release air to the support region 2291.

[0054] On the other hand, as described above, when the component retainer 200 is brought close to the base 100 by aligning the guide pins 210a, 210b with the guide retainers 110a, 110b, the guide pins 210a, 210b and the guide retainers 110a, 110b are secured. At this time, as Figure 7As shown, the first fastening part 220a and the second fastening part 120a are temporarily fastened. In the case of temporary connection, the rod region 2292 of the piston rod 229a pushes the steel ball 225a outward, so that the steel ball 225a contacts the seat surface 121a of the second fastening part 120a. However, a suitable gap may exist between the steel ball 225a and the seat surface 121a.

[0055] Reference Figure 8 When locking air LA is supplied through locking port 221a, piston rod 229a moves under the pressure of locking air LA and spring 226a (refer to symbol 299), thereby bringing steel ball 225a into close contact with seat surface 121a. Piston rod 229a moves in the direction where the spring force decreases. In this way, the first fastening part 220a and the second fastening part 120a are fastened together.

[0056] Figure 9 This is a flowchart illustrating a manufacturing method according to an embodiment of the present invention. Figure 10 It is used for explanation Figure 9 The diagram illustrates step S450. The case where the first fastening part is a pneumatic clamp and the second fastening part is a clamping block will be described below.

[0057] Reference Figure 9 The head assembly and assembly holder 200 are ready for alignment (S410).

[0058] Specifically, such as Figures 1 to 3 As shown, a head assembly including multiple aligned heads 10 is fixed to a head fixing region 101 of a base 100, wherein guide retainers 110a and 110b and clamping blocks 120a and 120b are provided around the head fixing region 101 of the base 100. An opening 201 is provided in the assembly retainer 200, and guide pins 210a and 210b and pneumatic clamps 220a and 220b are provided around the opening 201.

[0059] Next, the head assembly is positioned at the lower end of the assembly holder 200 (S420).

[0060] Subsequently, while connecting the guide pins 210a and 210b to the guide retainers 110a and 110b, the pneumatic clamps 220a and 220b are temporarily connected to the clamping blocks 120a and 120b (manually) (S430).

[0061] Specifically, such as Figure 5 and Figure 6 As shown, the guide pin (e.g., 210a) is secured by ball bearings 118a disposed on the inner circumferential surface of the hole 117a in the guide retainer (e.g., 110a). Figure 7As shown, when the guide pin 210a is fastened to the guide retainer 110a, the rod region 2292 of the pneumatic clamp (e.g., 220a) pushes the steel ball 225a outward, so that the steel ball 225a contacts the seat surface 121a of the clamping block (e.g., 120a).

[0062] Next, locking air is supplied to the pneumatic clamps 220a and 220b to completely secure the pneumatic clamps 220a and 220b to the clamping blocks 120a and 120b, thereby completing the emission module (S440) that ensures precision.

[0063] Specifically, such as Figure 8 As shown, when locking air LA is supplied through locking port 221a, piston rod 229a moves under the pressure of locking air LA and spring 226a (refer to reference numeral 299), thereby causing steel ball 225a to press tightly against seat surface 121a.

[0064] Then, the emission module is mounted on the head frame (S450). For example... Figure 10 As shown, the discharge module 1 is fixed below the head frame 600. The component retainer 200 is located above the base 100. In particular, the release buttons 115a and 115b of the guide retainers 110a and 110b (see...) Figure 1 It is exposed on the bottom surface of the base 100.

[0065] Figure 11 This is a flowchart illustrating a manufacturing method according to another embodiment of the present invention. Figure 11 This is a view used to illustrate the separation and reconnection of the base and component retainers during maintenance operations on multiple components. Figure 12 It is used for explanation Figure 11 The diagram shows step S520. Figure 13 It is used for explanation Figure 11 The diagram shows step S540.

[0066] First, refer to Figure 11 When maintenance is required on multiple components, the user releases air RA to pneumatic clamps 220a and 220b to separate pneumatic clamps 220a and 220b from clamping blocks 120a and 120b (S510).

[0067] Specifically, such as Figure 12As shown, a release port 222a is provided on the pneumatic clamp 220a. When release air RA is supplied to the release port 222a, the release air RA causes the piston rod 229a to move (see reference numeral 298). When the piston rod 229a moves, the steel ball 225a disengages from the seat surface 121a of the clamping block 120a and is placed in the groove 2293 of the piston rod 229a. Thus, the pneumatic clamp 220a and the clamping block 120a are completely separated.

[0068] Then, press the release buttons 115a, 115b exposed on the bottom surface of the base 100 to separate the guide pins 210a, 210b from the guide retainers 110a, 110b (S510).

[0069] Then, in step S530, at least a portion of the plurality of heads disposed on the base 100 is repaired or replaced.

[0070] Next, with the component retainer 200 fixed to the head frame 600, the base 100, which includes the repaired multiple heads 10, is reconnected to the component retainer 200.

[0071] Specifically, such as Figure 13 As shown, during maintenance, the component retainer 200 is not separated from the head frame 600. Only the base 100, to which the head 10 is fixed, can be separated from the component retainer 200 for maintenance.

[0072] When the base 100, including the repaired multiple heads 10, is re-secured to the component retainer 200, the pneumatic clamps 220a, 220b and the clamping blocks 120a, 120b are temporarily secured while the guide pins 210a, 210b and the guide retainers 110a, 110b are secured. The pneumatic clamps 220a, 220b and the clamping blocks 120a, 120b are then fully secured by supplying locking air to the pneumatic clamps 220a, 220b.

[0073] As described above, when using guide pins 210a, 210b and guide retainers 110a, 110b, pneumatic clamps 220a, 220b and clamping blocks 120a, 120b, precision can be maintained regardless of the operator's skill level. Furthermore, during maintenance, since only the base 100 needs to be separated without separating the component retainer 200, maintenance time is shortened.

[0074] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, those skilled in the art should understand that the present invention can be implemented in other specific forms without changing its technical concept or essential features. Therefore, the above embodiments should be understood as exemplary in all respects, and not restrictive.
