Description

Technical Field

[0001] This application belongs to the field of printing equipment technology, and specifically relates to a product printing positioning device and printing equipment. Background Technology

[0002] Large-size glass structures are now widely used in daily life, especially in automotive center consoles. To meet the demands of intelligent control, the current trend is to integrate the center console display, instrument panel information, and navigation interface into a single touch panel. This requires high-temperature bending of large-size flat glass according to the dimensions of the dashboard and navigation system of different car models. A graphical touch interface is then created using a printing process, replacing traditional physical buttons and achieving fully touch-based intelligent control.

[0003] Currently, planar screen printing technology is widely used in this field, but it cannot meet the printing needs of large-curvature curved glass. Existing curved screen printing equipment is mostly a rotary machine structure, capable of printing only on curved products with a specific curvature. When changing product types, it is necessary to replace the printing actuator, contour screen, and positioning fixture with a matching curvature, and after replacement, precision adjustments must be performed again. This process is cumbersome and time-consuming, hindering production flexibility and overall efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a product printing positioning device and printing equipment to solve the problems that existing flat screen printing technology cannot be applied to the printing needs of large-curvature curved glass and that the operation of curved screen printing equipment is cumbersome and time-consuming when changing products, which restricts the flexibility of production and overall efficiency.

[0005] To achieve the above objectives, the first aspect of this application provides a product printing positioning device, comprising: The fixture module is provided with a flexible product positioning surface, which is a plane, and a group of negative pressure adsorption holes for connecting to an external negative pressure device. A flattening and positioning module includes a lifting module, a convex flattening module disposed on the lifting module, and concave flattening modules distributed on both sides of the convex flattening module along a first direction. The concave flattening module is provided with a first controllable adsorption part and a concave pressure part, and the convex flattening module is provided with a second controllable adsorption part and a convex pressure part. The concave flattening module and the convex flattening module are both located above the flexible product positioning surface. The first direction is parallel to the flexible product positioning surface. The lifting module outputs lifting motion along the second direction, which is parallel to the normal of the flexible product positioning surface.

[0006] As a further improvement to the above technical solution: In some embodiments, the concave flattening module includes: The mounting base is mounted on the lifting module; A rolling assembly is slidably disposed on the mounting base along the first direction. The rolling assembly has a flattening roller, the axis of which is perpendicular to the first direction, and the wheel surface of which forms the concave pressure portion. A first suction cup assembly is slidably disposed on the rolling assembly along the second direction. The first suction cup assembly is provided with a first vacuum suction cup, and the first vacuum suction cup forms the first controllable adsorption part. In the second direction, in the initial state, the surface of the first vacuum chuck is closer to the flexible product positioning surface than the surface of the flattening roller.

[0007] In some embodiments, the concave flattening module further includes a first buffer assembly disposed on the side of the mounting base near the convex flattening module, wherein the first buffer assembly connects the mounting base and the rolling assembly.

[0008] In some embodiments, the concave flattening module further includes a second buffer assembly disposed at the upper end of the first suction cup assembly in the second direction, wherein the second buffer assembly connects the rolling assembly and the first suction cup assembly.

[0009] In some embodiments, the lifting module includes two longitudinal beams spaced apart along a third direction and two transverse beams spaced apart along the first direction, the transverse beams being located between the two longitudinal beams, the longitudinal beams having a first adjustment groove provided along the first direction, and the transverse beams being locked in the first adjustment grooves by a first locking assembly. Each of the crossbeams is provided with at least two concave flattening modules spaced apart along the third direction, and the third direction is parallel to the positioning surface of the flexible product.

[0010] In some embodiments, the crossbeam is provided with a second adjustment groove along the third direction, and the concave flattening module is locked in the second adjustment groove by a second locking component.

[0011] In some embodiments, the convex flattening module includes: A push-drive component is disposed on the lifting module; A convex pressure plate is driven and connected to the push-drive assembly. The convex pressure plate has a pressure pad on the side near the flexible product positioning surface. The side of the pressure pad near the flexible product positioning surface forms the convex pressure part. The second suction cup assembly is disposed on the convex pressure plate. The second suction cup assembly is provided with a second vacuum suction cup, which forms the second controllable adsorption part.

[0012] In some embodiments, the fixture module includes: The alignment platform module has adjustment degrees of freedom in at least one of the X-axis, Y-axis and θ-axis directions; A screen printing fixture module is disposed on the alignment platform module, and the flexible product positioning surface is provided on the side of the screen printing fixture module away from the alignment platform module.

[0013] To achieve the above objectives, a second aspect of this application provides a printing apparatus, including a product printing positioning device according to the first aspect described above.

[0014] As a further improvement to the above technical solution: In some embodiments, the printing equipment further includes a screen printing device, a visual inspection and positioning device, and a transfer device; The screen printing device is provided with a feeding station and a printing station along the first direction; Both the visual inspection and positioning device and the product printing positioning device are arranged at the loading station, with the detection end of the visual inspection and positioning device facing the product printing positioning device. The transfer device drives the connected jig module and transfers the jig module between the loading station and the printing station along the first direction.

[0015] Compared with the prior art, the product printing positioning device and printing equipment provided in this application have at least the following beneficial effects: The product printing positioning device provided in this application is used for printing positioning of flexible products with large curvature surfaces, such as large curvature glass. Since large curvature glass has a certain degree of flexibility, when printing on the concave surface of large curvature glass, the first controllable adsorption part of the concave flattening module in the flattening positioning module adsorbs the two ends of the concave surface of the glass. With the cooperation of the lifting module, the glass is transferred to the positioning surface of the flexible product. Then, the lifting module drives the entire flattening positioning module to descend, and the concave pressure part applies pressure to the two ends of the concave surface of the glass, so that the curved ends of the glass flatten and fit against the positioning surface of the flexible product. At this time, the external negative pressure device is activated, and the glass is adsorbed and positioned through the negative pressure adsorption hole group, so that the positioned glass remains flat, so as to facilitate subsequent printing on the flat surface.

[0016] When printing on the convex surface of large-curvature curved glass, the glass is first transferred to the flexible product positioning surface. Then, the lifting module drives the entire flattening and positioning module to descend. At this time, the first controllable adsorption part stops adsorption, and the second controllable adsorption part adsorbs the convex area in the middle of the glass. The convex pressure part applies pressure to the convex area in the middle of the glass, and under the combined action of the concave pressure part, the glass is flattened. The flattened glass fits against the flexible product positioning surface. At this time, the external negative pressure device is activated, and the glass is adsorbed and positioned through the negative pressure adsorption hole group, so that the positioned glass remains flat, which is convenient for subsequent printing on the flat surface.

[0017] Therefore, the product printing positioning device provided in this application can meet the printing needs of concave / convex surfaces of flat products and flexible products with large arc surfaces, making it more widely applicable. This allows flat printing equipment to print on flexible products with large arc surfaces without the need for additional configuration and adjustment of various functional modules in the printing equipment, saving debugging time, simplifying operation, and greatly improving production flexibility and overall efficiency.

[0021] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0022] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0023] On the one hand, please refer to Figure 1 , Figure 2 and Figure 3This embodiment provides a product printing positioning device 100 for printing positioning of flexible products with large curvature surfaces, such as for positioning when printing patterns on the surface of a large curvature glass for vehicle center console with a thickness of less than or equal to 1.3 mm.

[0024] It should be noted that glass of this thickness has a certain degree of flexibility and will not break during subsequent flattening and positioning. Thus, the product printing positioning device 100 provided in this application can be used to solve the shortcomings of conventional curved screen printing machines, such as low printing accuracy and troublesome product changeover.

[0025] The product printing positioning device 100 provided in this embodiment includes a jig module 110 and a flattening positioning module 120. The jig module 110 is provided with a flexible product positioning surface 1120 (e.g., Figure 3 As shown), the flexible product positioning surface 1120 is a plane. The flexible product positioning surface 1120 is provided with a negative pressure adsorption hole group 1121 that connects to an external negative pressure device. The negative pressure adsorption hole group 1121 is used for adsorption and positioning of the product to be printed, so as to ensure that the product is positioned on the flexible product positioning surface 1120 and prevent the product from moving or returning to its original curved shape.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The flattening positioning module 120 includes a lifting module 121, a concave flattening module 122, and a convex flattening module 123. The convex flattening module 123 is mounted on the lifting module 121. The convex flattening module 123 has at least one concave flattening module 122 on each of its two sides in the first direction. The concave flattening module 122 has a first controllable adsorption part and a concave pressure part. The convex flattening module 123 has a second controllable adsorption part and a convex pressure part. Both the first and second controllable adsorption parts are externally connected to a negative pressure device, and the adsorption can be turned on or off by controlling the negative pressure through a valve.

[0027] Furthermore, both the concave flattening module 122 and the convex flattening module 123 are located above the flexible product positioning surface 1120 to avoid interference with product loading. The first direction is parallel to the flexible product positioning surface 1120, and the lifting module 121 outputs lifting motion along a second direction, which is parallel to the normal to the flexible product positioning surface 1120. To more clearly describe the technical solution of this embodiment, arrow X indicates the first direction, arrow Y indicates the third direction, and arrow Z indicates the second direction in the accompanying drawings.

[0028] Thus, the product printing positioning device 100 provided in this embodiment is used for flexible products A0 with large curvature surfaces (such as...). Figure 5 The printing positioning (as shown) is used for printing positioning of large-curvature curved glass, because large-curvature curved glass has a certain degree of flexibility.

[0029] Please refer to the following: Figure 5 When printing on the concave surface of large-arc curved glass, the first controllable adsorption part of the concave flattening module 122 in the flattening positioning module 120 adsorbs the two ends of the concave surface of the glass. With the cooperation of the lifting module 121, the glass is transferred to the flexible product positioning surface 1120 to realize product suction and feeding.

[0030] After the product is loaded, the two ends of the glass are bent (warped) and do not fit against the flexible product positioning surface 1120. During the flattening operation, the lifting module 121 drives the entire flattening positioning module 120 to descend. The concave pressing part applies pressure to the two ends of the concave surface of the glass (at this time, the first controllable adsorption part maintains adsorption, and the convex pressing part does not participate in the work). Under the action of pressure, the bent ends of the glass are flattened and fit against the flexible product positioning surface 1120. At this time, the external negative pressure device is activated, and the glass is adsorbed and positioned through the negative pressure adsorption hole group 1121, so that the positioned glass remains flat, which is convenient for subsequent printing on the flat surface.

[0031] Please refer to the following: Figure 6 When printing on the convex surface of large-arc curved glass, the glass can be transferred to the flexible product positioning surface 1120 by the adsorption effect of the first controllable adsorption part to achieve product suction and feeding.

[0032] After the product is loaded, both ends of the glass are in contact with the flexible product positioning surface 1120, but the middle of the glass is raised due to bending. During the flattening operation, the lifting module 121 drives the entire flattening positioning module 120 to descend. At this time, the first controllable adsorption part stops adsorption (to ensure that the glass can generate relative displacement with the first controllable adsorption part when deformed). The second controllable adsorption part adsorbs the raised area in the middle of the glass for initial positioning. The convex pressure part applies pressure to the raised area in the middle of the glass, and under the combined action of the concave pressure part, the glass is flattened. The flattened glass fits against the flexible product positioning surface 1120. At this time, the external negative pressure device is activated, and the glass is adsorbed and positioned through the negative pressure adsorption hole group 1121, so that the positioned glass remains flat, so as to facilitate subsequent printing on the flat surface.

[0033] Therefore, the product printing positioning device 100 provided in this embodiment can meet the printing needs of flat products and flexible products A0 with large arc surfaces, including concave / convex surfaces. It has a wider range of applications, enabling flat printing equipment to print on flexible products A0 with large arc surfaces without the need for additional configuration and adjustment of various functional modules in the printing equipment. This saves debugging time, simplifies operation, and greatly improves production flexibility and overall efficiency.

[0034] To more clearly describe the technical solution of this application, the product printing positioning device 100 provided in this embodiment will be described in detail below: Please see Figure 2 and Figure 4 In this embodiment, four sets of concave flattening modules 122 are provided, and two sets of concave flattening modules 122 are provided on both sides of the convex flattening module 123, thereby improving the stability of product suction and flattening operations.

[0035] Please refer to the following: Figure 7 This embodiment describes one of the four concave flattening modules 122. The concave flattening module 122 includes a mounting base 1220, a rolling assembly 1221, and a first suction cup assembly 1222. The mounting base 1220 is disposed on the lifting module 121, that is, the lifting module 121 can drive the mounting base 1220 to move up and down in the vertical direction.

[0036] The rolling assembly 1221 is slidably mounted on the mounting base 1220 along a first direction. For example, a sliding rail and slider can be used for sliding engagement, or a groove and slider can be used. The rolling assembly 1221 includes a flattening roller 1221a, the axis of which is perpendicular to the first direction. The surface of the flattening roller 1221a forms the concave pressure area described above. During flattening and pressure application, the surface of the flattening roller 1221a makes rolling contact with the corresponding surface of the glass. Therefore, the surface of the flattening roller 1221a is covered with a soft rubber sleeve to prevent damage to the glass.

[0037] The first suction cup assembly 1222 is slidably disposed on the rolling assembly 1221 along the second direction. For example, a sliding rail and slider can be used to achieve a sliding engagement, or a sliding groove and slider can be used to achieve a sliding engagement. The first suction cup assembly 1222 is provided with a first vacuum suction cup 1222a, which forms the first controllable adsorption part described above. The first vacuum suction cup 1222a is externally connected to a negative pressure device, and the airflow between the first vacuum suction cup 1222a and the external negative pressure device is controlled by a valve.

[0038] In this embodiment, the second direction is perpendicular to the first direction. Along the second direction, in the initial state (before contacting the glass), the disk surface of the first vacuum suction cup 1222a is closer to the wheel surface of the flattening roller 1221a than the flexible product positioning surface 1120. This arrangement ensures that the first vacuum suction cup 1222a contacts the adsorption surface of the product, which is convenient for adsorbing and positioning the product.

[0039] like Figure 7As shown, the concave flattening module 122 also includes a first buffer component 1223. The first buffer component 1223 is disposed on the side of the mounting base 1220 near the convex flattening module 123. The first buffer component 1223 connects the mounting base 1220 and the rolling component 1221.

[0040] It is understandable that the flexible product positioning surface 1120 is usually set with a recessed groove structure. Therefore, during the rolling process, especially when the rolling assembly 1221 rolls to the step position at the edge of the recessed groove, it is easy to bump and make hard contact with the product in the lateral direction. Thus, by setting the first buffer assembly 1223, the rolling assembly 1221 is provided with buffering and shock absorption in the rolling direction to protect the product and the rolling assembly 1221.

[0041] Optionally, the first buffer assembly 1223 includes a first elastic buffer member and a first connecting plate. The first connecting plate is disposed on the rolling assembly 1221. One end of the first elastic buffer member is connected to the first connecting plate, and the other end is connected to the mounting base 1220. The first elastic buffer member is used to provide elastic buffering.

[0042] Optionally, the first elastic buffer can be a spring, elastic colloid, or sheet, etc.

[0043] like Figure 7 As shown, in some embodiments, the concave flattening module 122 further includes a second buffer component 1224, which is arranged at the upper end of the first suction cup component 1222 in the second direction. The second buffer component 1224 connects the rolling component 1221 and the first suction cup component 1222, thus providing a buffering effect in the second direction for the first suction cup component 1222.

[0044] Specifically, when applying pressure to the glass and flattening it, since the first vacuum suction cup 1222a of the first suction cup assembly 1222 contacts the product first, the roller of the rolling assembly 1221 is not in contact with the glass at this time. When the downward movement and pressure application continue, under the buffering effect of the second buffer assembly 1224, the first suction cup assembly 1222 retracts, and at this time the roller of the rolling assembly 1221 begins to contact the product. The second buffer assembly 1224 can prevent the first suction cup assembly 1222 from applying rigid pressure to the glass, and at the same time prevent excessive pressure from damaging the glass. Furthermore, after the pressure is released, the second buffer assembly 1224 can drive the first suction cup assembly 1222 to reset.

[0045] Optionally, the second buffer assembly 1224 includes a second elastic buffer member and a second connecting plate. The second connecting plate is disposed on the rolling assembly 1221 or the mounting base 1220. One end of the second elastic buffer member is connected to the second connecting plate, and the other end is connected to the end of the first suction cup assembly 1222 away from the first vacuum suction cup 1222a. The second elastic buffer member is used to provide elastic buffering.

[0046] Please see Figure 2 and Figure 4 The aforementioned lifting module 121 includes two longitudinal beams 1212 spaced apart along a third direction and two transverse beams 1213 spaced apart along a first direction. The transverse beams 1213 are located between the two longitudinal beams 1212. The longitudinal beams 1212 have a first adjusting groove 1212a arranged along the first direction, and the transverse beams 1213 are locked in the first adjusting groove 1212a by a first locking assembly. Each transverse beam 1213 has at least two concave flattening modules 122 spaced apart along a third direction. The third direction is parallel to the flexible product positioning surface 1120 and perpendicular to the first direction.

[0047] Understandably, the position of the crossbeam 1213 relative to the longitudinal beam 1212 in the first direction can be adjusted by releasing the locking action of the first locking assembly to accommodate glass of different sizes. Optionally, the first locking assembly may be a bolt and nut assembly.

[0048] Furthermore, the crossbeam 1213 is provided with a second adjustment groove 1213a along a third direction, and the concave flattening module 122 is locked within the second adjustment groove 1213a by a second locking assembly 1214. Specifically, the mounting base 1220 of the concave flattening module 122 is locked within the second adjustment groove 1213a by the second locking assembly 1214. Thus, it can be understood that the position of the concave flattening module 122 relative to the crossbeam 1213 in a third direction can be adjusted by releasing the locking action of the second locking assembly 1214 to accommodate glass of different sizes. Optionally, the second locking assembly 1214 can be a bolt and nut assembly.

[0049] Furthermore, the lifting module 121 also includes a lifting drive assembly 1210 and a lifting frame 1211. Two lifting drive assemblies 1210 are provided, arranged at intervals along a third direction and operating synchronously. A fixture module 110 is located between the two lifting drive assemblies 1210, and the lifting frame 1211 is arranged across the fixture module 110 along a third direction. Two longitudinal beams 1212 are mounted on the lifting frame 1211.

[0050] Optionally, the lifting drive assembly 1210 includes a hydraulic cylinder, a pneumatic cylinder, a linear motor, an electric cylinder, or a motor lead screw structure. It should be understood that the above are merely illustrative examples and should not be construed as limiting the scope of protection of this application.

[0051] Please see Figure 2 , Figure 4 and Figure 8The aforementioned convex flattening module 123 includes a push-drive assembly 1230, a convex pressure plate 1231, and a second suction cup assembly 1232. The push-drive assembly 1230 is mounted on the lifting module 121, specifically on the lifting frame 1211 of the lifting module 121. The convex pressure plate 1231 is driven to connect with the push-drive assembly 1230. A pressure-resistant rubber pad 1233 is provided on the side of the convex pressure plate 1231 near the flexible product positioning surface 1120. The pressure-resistant rubber pad 1233 forms a convex pressure application part on the side near the flexible product positioning surface 1120. The pressure-resistant rubber pad 1233 prevents rigid contact with the glass and also provides cushioning protection for the glass. The second suction cup assembly 1232 is mounted on the convex pressure plate 1231 and includes a second vacuum suction cup 1232a, which forms a second controllable adsorption part.

[0052] Understandably, when printing on the concave side of a large-curvature glass surface, the push-drive assembly 1230 moves the convex pressure plate 1231 upward to its upper limit position to avoid contact with the glass. When printing on the convex side of a large-curvature glass surface, the push-drive assembly 1230 moves the convex pressure plate 1231 downward and brings the second vacuum suction cup 1232a into contact with the glass for adsorption and positioning.

[0053] Optionally, the push drive assembly 1230 includes a hydraulic cylinder, a pneumatic cylinder, a linear motor, an electric cylinder, or a motor lead screw structure. It should be understood that the above are merely illustrative examples and should not be construed as limiting the scope of protection of this application.

[0054] Please see Figure 1 , Figure 2 and Figure 3 The aforementioned fixture module 110 includes a positioning platform module 111 and a screen printing fixture module 112. The positioning platform module 111 has adjustment degrees of freedom in at least one of the X-axis, Y-axis, and θ-axis directions; in this embodiment, the positioning platform module 111 simultaneously possesses adjustment degrees of freedom in all three directions (X-axis, Y-axis, and θ-axis), thus enabling better printing positioning adjustment. Adjustment in the X-axis and Y-axis directions can be achieved through a built-in lead screw and motor structure, while rotational adjustment in the θ-axis direction can be achieved through motor drive, preferably a servo motor or a stepper motor.

[0055] The screen printing fixture module 112 is mounted on the alignment platform module 111, and the side of the screen printing fixture module 112 away from the alignment platform module 111 is provided with a flexible product positioning surface 1120.

[0056] On the other hand, please see Figures 1 to 9 This embodiment also provides a printing device, and more particularly relates to a fully automatic embossing screen printing device. The printing device includes a product printing positioning device 100 provided according to the above embodiment.

[0057] The printing equipment also includes a screen printing unit 200, a vision inspection and positioning device 300, and a transfer device 400. The frame 210 of the screen printing unit 200 has a loading station 211 and a printing station 212 along a first direction. The vision inspection and positioning device 300 and the product printing positioning device 100 are both located at the loading station 211, with the detection end of the vision inspection and positioning device 300 facing the product printing positioning device 100. The transfer device 400 drives the connecting fixture module 110 and transfers the fixture module 110 between the loading station 211 and the printing station 212 along the first direction.

[0058] The screen printing apparatus 200 also includes a screen module 230 and a screen printing execution module 220 arranged above the screen module 230. The screen printing execution module 220 drives a squeegee to reciprocate so as to evenly distribute ink on the screen of the screen module 230.

[0059] The visual inspection and positioning device 300 works in conjunction with the alignment platform module 111. The visual inspection and positioning device 300 determines whether the flexible product positioning surface 1120 is aligned with the product through image acquisition. Otherwise, it controls the alignment platform module 111 to make adjustments through the device's controller (e.g., PLC) to ensure alignment.

[0060] Please see Figure 1 and Figure 9 In this embodiment, the visual inspection and positioning device 300 includes a mounting bracket 310, a camera 320, and an adjustment module 330. Multiple cameras 320 are provided, and at least one camera 320 can be mounted on one adjustment module 330. The imaging end of the camera 320 faces the fixture module 110 located at the loading station 211. The camera 320 may be a CCD camera 320.

[0061] The adjustment module 330 is a fine-tuning displacement stage, which has a Z-axis movement module, a Y-axis movement module, and an X-axis movement module. The lens and light source of the camera 320 are mounted on the Z-axis movement module of the fine-tuning displacement stage, which is then mounted on the Y-axis movement module. The Y-axis movement module is mounted on the X-axis movement module, and the X-axis movement module is mounted on the guide rail clamps to lock and adjust them into position. Thus, the camera 320 can be adjusted in the XYZ directions by utilizing the movement adjustability of the Z-axis, Y-axis, and X-axis movement modules and the guide rail clamps.

[0062] Please see Figure 1 The printing equipment also includes a feeding device 500 and a discharging device 600. The screen printing device 200 is also provided with a discharging station along the first direction, and the printing station 212 is located between the feeding station 211 and the discharging station.
