Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a pad printing device. Background Technology

[0002] Pad printing machines are printing equipment suitable for plastics, glass, metals, ceramics, and electronics. Pad printing is an indirect, concave pad printing technology that has become a major method for printing and decorating various object surfaces.

[0003] In related technologies, pad printing machines typically use an ink cup to apply ink to an etched plate, and the cup scrapes off excess ink as it moves. However, for substrates with curved surfaces, the flexible printing head cannot adjust its angle according to the curvature of the substrate, leading to uneven printing and distorted patterns, thus affecting product quality. This problem is particularly pronounced when the substrate is large or the printing surface is wide. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a pad printing device that avoids uneven printing and pattern distortion caused by misalignment between the printing mechanism and the substrate.

[0005] The technical effect to be achieved by this utility model is realized through the following technical solution:

[0006] This utility model provides a pad printing device, comprising:

[0007] The printing mechanism is slidably set along the first horizontal direction;

[0008] An ink application mechanism includes an etching plate and an ink container, wherein the etching plate is located below the printing mechanism, and the ink container is slidably disposed on the upper surface of the etching plate along a first horizontal direction; and

[0009] The carrier mechanism includes a fixed base and a carrier plate. The fixed base is located downstream of the printing mechanism, and the carrier plate is rotatably connected to the fixed base. The carrier plate has a placement area for placing the printing substrate.

[0010] The carrier plate rotates relative to the fixed base so that the front of the substrate faces the printing mechanism, and the printing mechanism absorbs the ink on the etching plate and prints the ink onto the substrate.

[0011] In some implementations, the pad printing device further includes a first slide rail, a slider, and a first driving member. The slider is slidably connected to the first slide rail, and the fixed base is connected to the slider. The first driving member is used to drive the fixed base to slide along a second horizontal direction, which is perpendicular to the first horizontal direction.

[0012] When the slider slides closer to the printing mechanism, the carrier plate rotates to a position where the front of the substrate faces the printing mechanism; when the slider slides away from the printing mechanism, the carrier plate rotates back to a preset angle.

[0013] In some implementations, the supporting mechanism further includes a plurality of positioning blocks, which surround the supporting plate, and the placement area is formed between the plurality of positioning blocks.

[0014] In this implementation, the substrate is placed in the placement area and its outer periphery is limited by multiple positioning blocks, thereby fixing the substrate in the placement area.

[0015] In some implementations, the bearing mechanism further includes a pressure block and a second driving member, the second driving member being driven to the pressure block so that the pressure block presses the substrate onto the bearing plate in a vertical direction.

[0016] In this implementation, after the substrate is placed in the placement area, the second driving member drives the pressure block to approach the substrate, thereby pressing and fixing the substrate onto the carrier plate.

[0017] In some implementations, the bearing mechanism further includes a first rotating block and a second rotating block, the first rotating block being rotatably connected to a first side of the fixed base, the second rotating block being rotatably connected to a second side of the fixed base, and the opposite sides of the bearing plate being connected to the first rotating block and the second rotating block, respectively.

[0018] In some implementations, the supporting mechanism further includes a third driving member, which is driven to connect to the first rotating block and / or the second rotating block.

[0019] In this implementation, the third driving component drives the first rotating block to rotate, thereby causing the bearing plate and the second rotating block to rotate. The first rotating block and the second rotating block make the bearing plate more balanced during rotation.

[0020] In some implementations, the printing mechanism includes a connecting plate, a flexible rubber head, and a fourth driving member, wherein the flexible rubber head is connected to the connecting plate, and the fourth driving member is driven to be connected to the connecting plate.

[0021] In this implementation, the fourth driving component drives the connecting plate to move, which in turn drives the soft rubber head to move, so that the soft rubber head can move along the first horizontal direction to approach or move away from the carrier mechanism, thereby printing on the substrate.

[0022] In some implementations, a fifth driving member is provided between the connecting plate and the flexible rubber head, and the fifth driving member is driven to be connected to the flexible rubber head so that the flexible rubber head can move in the vertical direction.

[0023] In some implementations, the connecting plate is provided with a second slide rail, and the fifth driving member has a groove that cooperates with the second slide rail, so that the soft rubber head can move along the second horizontal direction.

[0024] In some implementations, the pad printing apparatus further includes an ink removal mechanism located between the ink spreading mechanism and the carrier mechanism, for removing ink from the printing mechanism.

[0025] In this implementation, after the printing mechanism completes the printing of the substrate, it slides along the first horizontal direction to above the ink removal mechanism. The fifth driving member drives the soft rubber head to descend, so that the soft rubber head comes into contact with the ink removal mechanism to remove the ink.

[0026] In summary, this utility model has at least the following advantages:

[0027] The pad printing device provided by this utility model places the substrate in the placement area of ​​the carrier plate. The carrier plate rotates relative to the fixed seat, thereby causing the substrate to rotate so that the front of the substrate faces the printing mechanism. The printing mechanism slides along the first horizontal direction, absorbs the ink on the etching plate, and then prints the ink onto the substrate. Since the carrier plate can rotate relative to the fixed seat, the curved surface of the substrate can face the printing mechanism, avoiding the problems of uneven printing and pattern distortion caused by the printing mechanism and the substrate not being aligned. Even if the size and position of the curved surface of the substrate are not fixed, the curved surface of the substrate can be made to face the printing mechanism by adjusting the rotation angle of the carrier plate.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0042] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0043] Example 1:

[0044] Please see the appendix Figure 1 ~Appendix Figure 3 The pad printing device of this utility model includes a printing mechanism 100, an ink spreading mechanism 200, and a carrier mechanism 300.

[0045] In this regard, please combine Figure 1 and Figure 2 , Figure 1 The diagram illustrates the structural relationship between the printing mechanism 100, the ink spreading mechanism 200, and the carrier mechanism 300 in this embodiment of the present invention. Figure 2The diagram illustrates the specific structures of the ink spreading mechanism 200 and the carrier mechanism 300 in this embodiment of the present invention. Specifically, the printing mechanism 100 is slidably disposed along a first horizontal direction; the ink spreading mechanism 200 includes an etching plate 210 and an ink container 220, with the etching plate 210 located below the printing mechanism 100 and the ink container 220 slidably disposed on the upper surface of the etching plate 210 along the first horizontal direction; the carrier mechanism 300 includes a fixing base 310 and a carrier plate 320, with the fixing base 310 located downstream of the printing mechanism 100 and the carrier plate 320 rotatably connected to the fixing base 310, and the carrier plate 320 having a placement area 321 for placing the substrate 800. The carrier plate 320 rotates relative to the fixing base 310 so that the front of the substrate 800 faces the printing mechanism 100, and the printing mechanism 100 absorbs the ink on the etching plate 210 and prints the ink onto the substrate 800.

[0046] In this embodiment, when the ink cup 220 of the ink spreading mechanism 200 slides along the first horizontal direction, the ink is applied to the etching plate 210, and excess ink on the etching plate 210 is scraped off during the sliding process of the ink cup 220. The printing mechanism 100 is located above the ink spreading mechanism 200 and is used to absorb the ink on the etching plate 210 and print the ink on the substrate 800. The supporting mechanism 300 is located downstream of the printing mechanism 100 and is used to support the substrate 800, so that the front of the substrate 800 with the curved surface faces the printing mechanism 100, thereby making the printing surface of the substrate 800 face the printing mechanism 100, avoiding the problem of uneven printing and pattern distortion caused by the curvature of the printing surface.

[0047] Specifically, during printing, the substrate 800 is placed in the placement area 321 of the carrier plate 320. The carrier plate 320 rotates relative to the fixed base 310, thereby causing the substrate 800 to rotate, so that the front of the substrate 800 faces the printing mechanism 100. At the same time, the ink cup 220 slides along the first horizontal direction toward the carrier mechanism 300 to coat the etching plate 210 with ink, and then slides again along the first horizontal direction away from the carrier mechanism 300 to scrape off the excess ink on the etching plate 210. The printing mechanism 100 slides along the first horizontal direction, and after absorbing the ink on the etching plate 210, prints the ink onto the substrate 800.

[0048] It is understandable that, since the carrier plate 320 can rotate relative to the fixed base 310, the substrate 800 can adjust its angle according to the printing requirements. Even if the size and position of the curved surface of the substrate 800 are not fixed, the printing surface of the substrate 800 can be adjusted to face the printing mechanism 100. In this way, even if the volume of the substrate 800 is large, the printing effect is uniform.

[0049] In the aforementioned pad printing apparatus, the substrate 800 is placed in the placement area 321 of the carrier plate 320. The carrier plate 320 rotates relative to the fixed base 310, thereby causing the substrate 800 to rotate so that the front of the substrate 800 faces the printing mechanism 100. The printing mechanism 100 slides along the first horizontal direction, absorbs the ink on the etching plate 210, and then prints the ink onto the substrate 800. Since the carrier plate 320 can rotate relative to the fixed base 310, the curved surface of the substrate 800 can face the printing mechanism 100, avoiding the problems of uneven printing and pattern distortion caused by the printing mechanism 100 and the substrate 800 not being aligned. Even if the size and position of the curved surface of the substrate 800 are not fixed, the curved surface of the substrate 800 can be made to face the printing mechanism 100 by adjusting the rotation angle of the carrier plate 320.

[0050] In some preferred embodiments, please refer to Figure 1 , Figure 1 The diagram illustrates the structural relationship between the first slide rail 400, the slider 500, and the supporting mechanism 300 in this embodiment of the present invention. Specifically, the pad printing device further includes the first slide rail 400, the slider 500, and the first driving member 600. The slider 500 is slidably connected to the first slide rail 400, and the fixed seat 310 is connected to the slider 500. The first driving member 600 is used to drive the fixed seat 310 to slide along a second horizontal direction, which is perpendicular to the first horizontal direction. When the slider 500 slides closer to the printing mechanism 100, the supporting plate 320 rotates to a position where the front of the substrate 800 faces the printing mechanism 100. When the slider 500 slides away from the printing mechanism 100, the supporting plate 320 rotates back to a preset angle.

[0051] In this embodiment, the first slide rail 400 extends along the second horizontal direction. The fixed base 310 is slidably connected to the first slide rail 400 via the slider 500. The first driving member 600 drives the fixed base 310 to move, so that the carrying mechanism 300 slides along the second horizontal direction closer to the printing mechanism 100. The carrying plate 320 rotates to a position where the front of the substrate 800 faces the printing mechanism 100, allowing the printing mechanism 100 to print on the substrate 800. After printing is completed, the first driving member 600 drives the fixed base 310 to slide away from the printing mechanism 100, and the carrying plate 320 rotates back to a preset angle, facilitating the vertical removal and placement of the substrate 800 by an external mechanism. Thus, when the substrate 800 is large, the method of vertical removal and placement of the substrate 800 is more labor-saving and saves space.

[0052] In some preferred embodiments, please refer to Figure 3 , Figure 3The diagram illustrates the structural relationship between the positioning block 330 and the carrier plate 320 in this embodiment of the invention. Specifically, the carrier mechanism 300 further includes multiple positioning blocks 330, which surround the carrier plate 320, and a placement area 321 is formed between the multiple positioning blocks 330. The substrate 800 is placed in the placement area 321, and its outer periphery is limited by the multiple positioning blocks 330, thereby fixing the substrate 800 within the placement area 321. Furthermore, the positioning blocks 330 have positioning grooves, and the outer periphery of the substrate 800 is engaged in the positioning grooves, thereby ensuring the stability of the substrate 800.

[0053] In some preferred embodiments, the carrier mechanism 300 further includes a pressure block 340 and a second driving member 350. The second driving member 350 is driven and connected to the pressure block 340 so that the pressure block 340 presses the substrate 800 onto the carrier plate 320 in a vertical direction. After the substrate 800 is placed in the placement area 321, the second driving member 350 drives the pressure block 340 closer to the substrate 800, thereby pressing and fixing the substrate 800 onto the carrier plate 320. After printing is completed, the second driving member 350 drives the pressure block 340 away from the substrate 800, thereby releasing the pressing state of the substrate 800 so that an external device can remove the substrate 800 from the placement area 321.

[0054] In some preferred embodiments, the supporting mechanism 300 further includes a first rotating block 360 and a second rotating block 370. The first rotating block 360 is rotatably connected to a first side of the fixed base 310, and the second rotating block 370 is rotatably connected to a second side of the fixed base 310. The opposite sides of the supporting plate 320 are respectively connected to the first rotating block 360 and the second rotating block 370. The opposite sides of the supporting plate 320 are rotatably connected to the fixed base 310 via the first rotating block 360 and the second rotating block 370. When the first rotating block 360 and the second rotating block 370 rotate, they drive the supporting plate 320 to rotate, ensuring the balance and stability of the supporting plate 320 during rotation.

[0055] In some more preferred embodiments, the support mechanism 300 further includes a third driving member 380, which drives the first rotating block 360 and / or the second rotating block 370 to rotate. The third driving member 380 drives the first rotating block 360 and / or the second rotating block 370 to rotate, thereby causing the support plate 320 to rotate. In this embodiment, the third driving member 380 drives the first rotating block 360 to rotate, thereby driving the support plate 320 and the second rotating block 370 to rotate. The first rotating block 360 and the second rotating block 370 make the support plate 320 more balanced during rotation, and by driving only one rotating block to rotate while the other rotating block is driven, the support plate 320 can rotate smoothly while saving energy.

[0056] Example 2:

[0057] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the pad printing device of this utility model. Please refer to the appendix. Figure 4 .

[0058] The printing mechanism 100 includes a connecting plate 110, a flexible rubber head 120, and a fourth driving member 130. The flexible rubber head 120 is connected to the connecting plate 110, and the fourth driving member 130 is driven to be connected to the connecting plate 110.

[0059] In this embodiment, the fourth driving member 130 drives the connecting plate 110 to move, which in turn drives the flexible ink head 120 to move, so that the flexible ink head 120 can move along the first horizontal direction to approach or move away from the carrier mechanism 300, thereby printing on the substrate 800.

[0060] In some preferred embodiments, a fifth driving member 140 is further provided between the connecting plate 110 and the flexible ink pad 120. The fifth driving member 140 is driven to connect to the flexible ink pad 120 so that the flexible ink pad 120 can move vertically. The fifth driving member 140 drives the flexible ink pad 120 closer to the etching plate 210. After absorbing ink, the fifth driving member 140 drives the flexible ink pad 120 away from the etching plate 210. The fourth driving member 130 drives the flexible ink pad 120 closer to the carrier mechanism 300. The fifth driving member 140 drives the flexible ink pad 120 down to abut against the substrate 800, thereby realizing the printing on the substrate 800.

[0061] In some more preferred embodiments, the connecting plate 110 is provided with a second slide rail 111, and the fifth driving member 140 has a groove 141 that cooperates with the second slide rail 111, so that the flexible printing head 120 can move along the second horizontal direction. This allows the flexible printing head 120 to be adjusted in position relative to the substrate 800 along the second horizontal direction, thereby meeting more different printing needs.

[0062] Example 3:

[0063] The difference between this embodiment and Embodiment 2 is that this embodiment further optimizes the structure of the pad printing device of this utility model. Please refer to the appendix. Figure 4 .

[0064] The pad printing apparatus also includes an ink removal mechanism 700, which is located between the ink spreading mechanism 200 and the carrier mechanism 300, and is used to remove ink from the printing mechanism 100.

[0065] In this embodiment, after the printing mechanism 100 completes the printing of the substrate 800, it slides along the first horizontal direction above the ink removal mechanism 700. The fifth driving member 140 drives the flexible rubber head 120 to descend, so that the flexible rubber head 120 abuts against the ink removal mechanism 700 to remove ink. Then, the fifth driving member 140 drives the flexible rubber head 120 to rise and move above the etching plate 210 for the next printing operation. In this way, the flexible rubber head 120 maintains good printing performance during repeated use, and avoids excess ink accumulating on the flexible rubber head 120, thereby affecting the printing effect.

[0066] In some preferred embodiments, the ink removal mechanism 700 includes a mounting frame with an adhesive layer. The adhesive layer is used to remove excess ink from the flexible printing head 120, preventing excess ink from accumulating on the flexible printing head 120 and thus affecting the printing effect.

[0067] In this pad printing device, the substrate 800 is placed in the placement area 321 of the carrier plate 320. The carrier plate 320 rotates relative to the fixed base 310, thereby causing the substrate 800 to rotate so that the front of the substrate 800 faces the printing mechanism 100. The printing mechanism 100 slides along the first horizontal direction, absorbs the ink on the etching plate 210, and then prints the ink onto the substrate 800. Since the carrier plate 320 can rotate relative to the fixed base 310, the curved surface of the substrate 800 can face the printing mechanism 100, avoiding the problems of uneven printing and pattern distortion caused by the printing mechanism 100 and the substrate 800 not being aligned. Even if the size and position of the curved surface of the substrate 800 are not fixed, the curved surface of the substrate 800 can be made to face the printing mechanism 100 by adjusting the rotation angle of the carrier plate 320.

[0068] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0070] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0071] In this invention, unless otherwise expressly specified and limited, "above or below" the first feature may include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on" the first feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the first feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0072] Although the description of this utility model has been given in conjunction with the specific embodiments described above, it is obvious to those skilled in the art that many substitutions, modifications, and variations can be made based on the above description. Therefore, all such substitutions, modifications, and variations are included within the spirit and scope of the appended claims.
