Description

Technical Field

[0001] This utility model relates to the field of printing technology, and specifically to a surface treatment device for planar optical elements. Background Technology

[0002] After the window film hardens, a hardened film adheres to its surface. Screen printing has poor adhesion to the hardened film, so the window film needs to be plasma-treated before printing. However, plasma-treated window films and untreated window films cannot be distinguished by the naked eye, which leads to the printing of untreated window films during printing, resulting in the film being removed after the window films are delivered to the customer. In addition, the existing equipment prints on single pieces, which affects the output. Utility Model Content

[0003] The purpose of this invention is to provide a surface treatment device for planar optical elements.

[0004] This utility model provides the following technical solution:

[0005] This utility model proposes a surface treatment device for planar optical elements, including a tooling platform, a plasma generator and a screen printing machine disposed on the tooling platform, and a pair of parallel double guide rails disposed below the screen printing plate of the screen printing machine on the tooling platform. A first worktable driven by a first slide module is disposed between the upper guide rails of the double guide rails, and a second worktable driven by a second slide module is disposed between the side guide rails of the double guide rails. The vertical height of the first worktable is higher than that of the second worktable. The plasma generator is used for plasma treatment of the optical elements on the worktable before printing.

[0006] Furthermore, the first workbench has a plurality of first adsorption ports on its upper surface and a first connecting hole on its rear end face, the first connecting hole being connected to the first adsorption ports; the second workbench has a plurality of second adsorption ports on its upper surface and a second connecting hole on its rear end face, the second connecting hole being connected to the second adsorption ports.

[0007] Furthermore, it also includes a tooling frame set on the tooling platform, on which a third slide module is horizontally fixed, and a fourth slide module is vertically fixed on the slide of the third slide module, and the plasma generator is fixed on the slide of the fourth slide module.

[0008] Furthermore, the dual guide rails are a guide block with rails on both the upper surface and the sidewalls.

[0009] Furthermore, it also includes a first slide block that cooperates with the upper guide rail of the dual guide rails and a second slide block that cooperates with the side guide rails of the dual guide rails. The first worktable is fixed on the first slide block, and the second worktable is fixed on the second slide block.

[0010] Furthermore, a slot parallel to the dual guide rails is provided on the tooling platform. The slot is located below the second slide block. The second slide block extends with a protrusion that passes through the slot. The second slide module is fixed to the back of the tooling platform, and the slide of the second slide module is fixedly connected to the protrusion.

[0011] Furthermore, the first slide module is fixed on the tooling platform, the first slide module is located outside the double guide rails and parallel to the double guide rails, and the slide of the first slide module is fixedly connected to the first slide base.

[0012] Compared with existing technologies, this utility model combines plasma printing and screen printing, allowing direct printing on the plasma-printed window film, thus avoiding direct printing on un-plasma-printed window films and reducing the inflow of defective products to customers; at the same time, by utilizing a dual-station structure, plasma printing and screen printing can be carried out in cycles, improving work efficiency and reducing the need for one plasma printing operator, thereby reducing labor costs.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] See Figure 1 and Figure 6 In one embodiment of this utility model, a planar optical element surface treatment device includes a tooling platform 1, a plasma generator 2 and a screen printing machine 3 disposed on the tooling platform 1. A pair of parallel double guide rails 4 are also disposed on the tooling platform 1 below the screen printing screen 32 of the screen printing machine. A first worktable 6 driven by a first slide module 5 is disposed between the upper guide rails of the double guide rails 4, and a second worktable 8 driven by a second slide module is disposed between the side guide rails of the double guide rails 4. The vertical height of the first worktable 6 is higher than that of the second worktable 8. The plasma generator 9 is used for plasma treatment of the optical element 00 on the worktable before printing. In practical application, the operator places the optical element 00 on the second worktable 8. After plasma treatment by the plasma generator 9, the second slide module moves the second worktable 8 and the optical element on the platform to below the screen printing screen 32 for printing by the screen printing machine 3. Simultaneously, the first slide module 5 moves the first worktable 6 below the screen printing screen 32 to below the plasma generator 9. The first and second working platforms alternate between printing and plasma processing. The staff only needs to pick up and put down the optical components on the first and second working platforms, which improves work efficiency and reduces the number of plasma processing staff, thus reducing labor costs.

[0023] See Figures 2-5In one embodiment of this utility model, the upper surface of the first workbench 6 is provided with a plurality of first adsorption ports 61, and the rear end face of the first workbench 6 is provided with a first connecting hole 62, which is connected to the first adsorption ports 61; the upper surface of the second workbench 8 is provided with a plurality of second adsorption ports 81, and the rear end face of the second workbench 8 is provided with a second connecting hole 82, which is connected to the second adsorption ports 81; in practical applications, both the first connecting hole 62 and the second connecting hole 82 are connected to an external adsorption device to ensure the firm adsorption of the optical element 00 on the platform and to ensure the quality of the optical element after plasma processing and printing.

[0024] See Figure 6 In the above embodiments, the tooling platform 1 is further provided with a first negative pressure button 16 for activating the adsorption of the first working platform 6; the tooling platform 1 is also provided with a second negative pressure button 17 for activating the adsorption of the second working platform 8; this facilitates the operator's control of the platform's adsorption. The circuit connection is a conventional connection and will not be described in detail; only the protective structure is considered.

[0025] See Figure 1 In one embodiment of this utility model, a tooling frame 10 is further provided on the tooling platform 1. A third slide module 11 is horizontally fixed on the tooling frame 10, and a fourth slide module 12 is vertically fixed on the slide of the third slide module 11. The plasma generator 9 is fixed on the slide of the fourth slide module 12. The slide of the third slide module 11 drives the lateral movement of the plasma generator of the fourth slide module 12. The slide of the fourth slide module drives the longitudinal movement of the plasma generator 9. This realizes the mobility of the plasma generator 9 and increases the flexibility of plasma processing.

[0026] See Figure 3 In one embodiment of this utility model, the double guide rail 4 is a guide block 42 with rails 41 on both the upper surface and the side wall; it can realize the first worktable 6 and the second worktable 8 moving alternately on the double guide rail 4 at the same time, while effectively utilizing space and materials.

[0027] See Figure 3 In one embodiment of this utility model, it further includes a first slide block 13 that cooperates with the upper guide rail of the double guide rail 4 and a second slide block 14 that cooperates with the side guide rail of the double guide rail 4. The first worktable 6 is fixed on the first slide block 13 and the second worktable 8 is fixed on the second slide block 14. The double guide rail 4 and the worktable are connected through the slide block, which is convenient and ensures that the worktable does not derail.

[0028] See Figure 6 and Figure 7In the above embodiment, a slot 15 parallel to the double guide rails 4 is opened on the tooling platform 1. The slot 15 is located below the second slide block 14. The second slide block 14 extends with a protrusion 140 passing through the slot 15. The second slide module 7 is fixed to the back of the tooling platform 1, and the slide of the second slide module 7 is fixedly connected to the protrusion 140. The second slide block 14 and the second worktable 8 are moved by the slide of the second rodless cylinder 7.

[0029] See Figure 1 and Figure 5 In the above embodiment, the first slide module 5 is fixed on the tooling platform 1. The first slide module 5 is located outside the double guide rail 4 and parallel to the double guide rail 4. The slide of the first slide module 5 is fixedly connected to the first slide block 13. The slide of the first slide module 5 drives the movement of the first slide block 13 and the first worktable 6.

[0030] In practical applications, the operator places the optical element on the second working platform, presses the first negative pressure button to turn on the negative pressure, and performs plasma treatment by the plasma generator. Then, the second slide module moves the second working platform and the optical element on the platform to below the screen printing plate (at the same time, the first slide module moves the first working platform below the screen printing plate to below the plasma generator). The optical product on the second working platform is printed by the screen printing machine (at the same time, the operator presses the second negative pressure button to turn off the negative pressure, removes the optical element from the second working platform, and places a new optical element for plasma treatment). The reverse is also true, so that the first and second working platforms alternately perform printing and plasma treatment.

[0031] In this utility model, the screen printing stencil 32, screen clamp 34, fan 33, control panel 35, machine head 31, and some unmarked components (such as the lower housing structure, wheels, etc.) are all existing structures of screen printing machines and belong to prior art, so they will not be described in detail in this utility model. The design features of this utility model are the two alternating worktables below the screen printing stencil and the movable plasma generator installed above the worktables.

[0032] In this utility model, the plasma generator, slide module and other equipment are existing equipment and will not be described in detail.

[0033] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
