Description

Technical Field

[0001] This utility model relates to the field of printer technology, and in particular to a flexible circuit mounting structure for a printer and a printer. Background Technology

[0002] In existing printers, flexible circuit boards (such as FPCs) are often fixed to the housing using clips, screws, or positioning posts. However, in devices such as portable printers and mini printers, or in printers where space is limited, such fixing structures often fail to meet actual installation requirements. Utility Model Content

[0003] To solve the above technical problems, this utility model provides a flexible circuit mounting structure for a printer and a printer, wherein the flexible circuit mounting structure for the printer includes: Printer housing, the printer housing has a mounting part; A flexible circuit board, wherein at least one side of the flexible circuit board is adhesively bonded to the mounting portion; A padding layer is provided on the other side of the flexible circuit board; A pressure shaft is disposed on the surface of the pad layer, and the pressure shaft presses the pad layer toward the flexible circuit board.

[0004] Preferably, the mounting portion has a groove structure.

[0005] Preferably, the surface of the pad layer near the pressure shaft is smooth.

[0006] This utility model also provides a printer that adopts any of the printer flexible circuit mounting structures described above.

[0007] The flexible circuit mounting structure for printers provided by this utility model directly fixes the flexible circuit board to the housing by adhesive bonding, eliminating the space required by traditional mechanical structures such as clips, screws, and positioning posts. This greatly reduces the three-dimensional space required for installation, making it particularly suitable for miniaturized and portable printers with compact internal layouts. Furthermore, through the combination of a pad and a pressure roller, the pressure roller presses against the flexible circuit board through the pad, while the adhesive provides bonding force across the entire plane, and the pressure roller provides vertical pressure. The combination of these two forces ensures that the flexible circuit board will not fall off or shift under vibration or movement conditions, greatly enhancing the connection strength of the adhesive part of the flexible circuit board. The elasticity of the pad ensures uniform pressure distribution, providing good buffering and protection for the flexible circuit board. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0011] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0012] This utility model provides a flexible circuit mounting structure for a printer and a printer, wherein the flexible circuit mounting structure for the printer includes: Printer housing 10, printer housing 10 is provided with mounting part 11; The flexible circuit board 12 is at least partially bonded to the mounting portion 11 on one side. A padding layer 13 is disposed on the other side of the flexible circuit board 12; A pressure shaft 14 is disposed on the surface of the pad 13, and the pressure shaft 14 presses the pad 13 against the flexible circuit board 12.

[0013] In specific implementation, such as Figures 1-3 The printer's flexible circuit mounting structure includes: The printer housing 10 is a conventional printer housing structure, which will not be described in detail here. The printer housing 10 is provided with a mounting part 11, which includes, but is not limited to, a groove structure. Setting the mounting part as a groove structure provides a natural positioning reference and placement space for the installation of the flexible circuit board. During assembly, the operator can quickly and accurately place the FPC into the groove, avoiding alignment deviations during pasting and improving assembly accuracy and efficiency. A flexible circuit board 12, one side of one end of which is glued to the mounting portion 11; A padding layer 13 is disposed on the other side of the flexible circuit board 12, and the padding layer 13 is adhesively bonded to the side wall of the printer housing 10 or the other side of the flexible circuit board 12; the padding layer 13 is made of insulating rubber or sponge materials, including but not limited to. The pressure shaft 14 is disposed on the surface of the pad 13. The pressure shaft 14 presses the pad 13 against the flexible circuit board 12. During installation, the pad 13 can be installed first or the pad 13 can be squeezed into the space between the pressure shaft 14 and the flexible circuit board 12.

[0014] The flexible circuit mounting structure for printers provided in this embodiment of the utility model directly fixes the flexible circuit board to the housing by adhesive bonding, eliminating the space required by traditional mechanical structures such as clips, screws, and positioning posts. This greatly reduces the three-dimensional space required for installation, making it particularly suitable for miniaturized and portable printers with compact internal layouts. Furthermore, through the combination of a pad and a pressure roller, the pressure roller presses against the flexible circuit board through the pad, the adhesive provides bonding force across the entire plane, and the pressure roller provides vertical pressure. The combination of these two forces ensures that the flexible circuit board will not fall off or shift under conditions of vibration or movement, greatly enhancing the connection strength of the adhesive part of the flexible circuit board. The elasticity of the pad ensures uniform pressure distribution, providing good buffering and protection for the flexible circuit board.

[0015] In practice, the flexible circuit board is installed on one side of the existing rotating shaft (e.g., as a paper feeding roller, pressure roller, cover opening connecting roller, etc.), and this rotating shaft replaces the pressure shaft 14, reducing the number of pressure shaft 14 components and reducing production costs.

[0016] In specific implementation, the surface of the pad 13 near the pressure shaft 14 is smooth. Release paper can be placed on the surface, and the release paper is connected to the pad 13 by means including but not limited to adhesive bonding. The smooth surface design of the pad 13 greatly reduces the friction between the pressure shaft 14 and the pad 13. When the pressure shaft 14 is a rotating shaft in the existing structure, the smooth surface ensures that the pressure shaft 14 can rotate smoothly and will not be "locked up" by the pad due to excessive friction, resulting in poor rotation, jamming, or damage to the drive motor, thus ensuring the normal function of the printer.

[0017] This utility model also provides a printer that adopts any of the printer flexible circuit mounting structures described above.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
