Description

Technical Field

[0001] This utility model relates to the field of glass product manufacturing technology, and in particular to a screen printing base for flat sheets. Background Technology

[0002] In today's watch industry, flat glass watch cases still have a significant market share. During assembly, watch cases require multiple layers of ink printing, and the current printing process primarily uses screen printing. Screen printing is a crucial and widely used technology in watch manufacturing. It utilizes a screen printing plate, using a squeegee to force ink through the mesh, thus precisely printing patterns, text, markings, brand logos, luminous markers, etc., onto a substrate (usually the watch case, dial, bezel, hands, or case back). Currently, the screen printing base for flat watch lenses is an integrated, single-piece printing unit, fixed to the machine platform with screws. Alternatively, as disclosed in patent document CN211683960U, entitled "A Multi-Piece Glass Base," a multi-piece glass base is designed to eliminate the need for manual printing of individual glass pieces. Instead, multiple glass covers are placed simultaneously into the grooves of this invention. Different grooves can accommodate glass covers of different sizes. The invention is then fixed to the screen printing machine, the machine is started, and printing begins. The printed product and base can then be directly fed into the watch drying line and baking line for baking.

[0003] However, the above-mentioned technical solutions involve complex and inefficient installation and disassembly of the base plate and subframe. Furthermore, they cannot quickly switch between different shaped flat glass covers during production. Therefore, it is necessary to develop a solution that employs a newer technical design, has a simple structure, and allows for cleaning of the base, reducing material waste, thereby addressing these issues.

[0035] To further understand the utility model content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings: like Figure 1-4 As shown, the screen printing base for flat glass covers includes a base 1 for fixing to the processing platform of a screen printing equipment and a screen printing stencil 2 for supporting the flat glass cover. The base 1 is equipped with a vacuum suction structure 3. The screen printing stencil 2 is detachably connected to the base 1 via the screen printing stencil 2. The screen printing stencil 2 is equipped with a screen printing groove 21 for placing the flat glass cover. In this embodiment, by setting up a vacuum suction structure, which is connected to an external vacuum suction device, during installation, the vacuum suction device starts working, creating a vacuum state inside the vacuum structure, allowing the screen printing stencil and base to be fixedly connected. When the vacuum suction device stops working, air enters the vacuum structure, creating a non-vacuum state inside the vacuum structure, allowing the screen printing stencil and base to be disassembled. This allows for the replacement of different screen printing stencils for flat glass covers of different shapes, and facilitates the removal and cleaning of the screen printing stencil, improving cleaning efficiency. Only the screen printing stencil needs to be replaced each time, while the base can be used for a long time, greatly saving material waste. Of course, it is not limited to this; it can be any other device that allows for a detachable connection between the screen printing stencil and the base.

[0036] Specifically, such as Figure 3 , 4As shown, the vacuum suction structure 3 includes a vacuum chamber 31 and a base suction port 32. Both the vacuum chamber 31 and the base suction port 32 are disposed on the base 1, and the base suction port 32 is connected to an external vacuum suction device. In this embodiment, when the vacuum suction device starts working, it creates a vacuum in the vacuum chamber through the base suction port, thereby fixing the screen printing stencil to the base. When the vacuum suction device stops working, air enters the vacuum chamber, and the vacuum chamber is in a non-vacuum state, allowing the screen printing stencil to be detached from the base. Of course, this is not limited to this; any other device capable of detachably connecting the screen printing stencil and the base can be used.

[0037] Specifically, the screen printing groove 21 is provided with a screen plate suction hole 22, which is connected to the vacuum chamber 31 and the base suction hole 32. In this embodiment, by providing the screen plate suction hole, the vacuum suction device starts working, creating a vacuum state between the flat glass cover plate placed on the screen printing groove and the screen printing groove, thus fixing the flat glass cover plate on the screen printing groove. When the vacuum suction device stops working, air enters the space between the flat glass cover plate placed on the screen printing groove and the screen printing groove, creating a non-vacuum state, allowing the flat glass cover plate on the screen printing groove to be removed. Of course, this is not limited to this; other devices capable of vacuum suction fixing and disassembly of the flat glass cover plate on the screen printing groove can be used.

[0038] Specifically, such as Figure 1 , 2 As shown, at least one screen printing groove 21 is provided. In this embodiment, nine screen printing grooves are provided. This arrangement allows for the simultaneous processing of nine flat glass cover plates, effectively improving processing efficiency. Of course, the number of screen printing grooves is not limited to this; any other groove capable of processing multiple flat glass cover plates simultaneously can be used.

[0039] Specifically, the base 1 is provided with a mounting groove 11 for mounting the screen printing stencil 2, and the mounting groove 11 matches the screen printing stencil 2. In this embodiment, the mounting groove facilitates the operator's installation of the screen printing stencil, and the upper surface of the screen printing stencil and the upper surface of the base are on the same horizontal plane, which facilitates the screen printing processing of the flat glass cover. Of course, it is not limited to this; any other design that facilitates the operator's installation of the screen printing stencil and the screen printing processing of the flat glass cover can be used.

[0040] Specifically, the base 1 is provided with a screen printing stencil loading and unloading slot 12 for easy loading and unloading of the screen printing stencil 2. In this embodiment, the screen printing stencil loading and unloading slot facilitates the operator's loading and unloading of the screen printing stencil. Of course, it is not limited to this; it can be any other slot that facilitates the operator's loading and unloading of the screen printing stencil.

[0041] Specifically, the screen printing stencil 2 is provided with a glass loading and unloading slot 23 for easy handling of the flat glass cover. In this embodiment, the glass loading and unloading slot facilitates the operator's handling of the flat glass cover. Of course, it is not limited to this; any other design that facilitates the operator's handling of the flat glass cover is acceptable.

[0042] Specifically, such as Figure 1 , 2 As shown, the screen printing groove 21 can be circular, rectangular, hexagonal, or octagonal. In this embodiment, the screen printing groove is circular. Different shapes of screen printing grooves are suitable for flat glass covers of different shapes. Of course, the shape of the screen printing groove is not limited to this; it can be any other shape or structure that can meet the processing needs of products of different shapes.

[0043] Specifically, the screen printing stencil 2 is made of Teflon or silicone. In this embodiment, the screen printing stencil is made of Teflon. Choosing this material effectively reduces the risk of scratching the product. Of course, the material of the screen printing stencil is not limited to this; it can be any material that effectively reduces the risk of scratching the product. Specifically, the base 1 and the screen printing equipment processing platform are connected by a threaded connection. In this embodiment, the threaded connection makes the base and the processing platform more securely fixed. Of course, the connection method between the base and the screen printing equipment processing platform is not limited to this; other connection methods that can improve the connection strength between the two can be used.

[0044] Working Principle: During operation, the operator fixes the base onto the processing platform of the screen printing equipment. A matching screen printing stencil is selected based on the flat glass cover to be processed. The stencil has nine printing slots. The stencil is placed in the mounting slot, and the flat glass cover to be processed is placed in the printing slot. An external vacuum suction device is connected through the suction port of the base. The vacuum suction device creates a vacuum state between the vacuum chamber, the flat glass cover, and the printing slots, thus fixing the stencil and the flat glass cover. For disassembly, the vacuum suction device stops working, and air enters the space between the vacuum chamber, the flat glass cover, and the printing slots, creating a non-vacuum state, allowing for disassembly of the vacuum chamber, the flat glass cover, and the printing slots. The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
