Rigid-flex board press-fit board surface cleaning device

Abstract

The invention discloses a rigid-flex board press-fit board surface cleaning device which comprises a workbench, a fixing frame is fixedly installed on the workbench, a first fixing plate is fixedly installed at the lower end of the fixing frame through a connecting column, two sets of cleaning brushes are rotatably arranged at the lower end of the first fixing plate, and an electric push rod is fixedly installed on the workbench. A second fixing plate is fixedly installed at one end of a piston rod of the electric push rod, a groove is formed in the second fixing plate, a cleaning roller is rotatably arranged in the groove, an electric sliding table is fixedly installed on the inner wall of the fixing frame, and a supporting plate is fixedly installed on a sliding base of the electric sliding table. Dust and impurities attached to the surfaces of the flexible circuit board and the hard circuit board can be cleaned in time, the surfaces of the circuit boards are smoother, damage to the surfaces of the circuit boards can be reduced in the pressing process, and the product quality can be improved to a certain degree.

Description

technical field [0001] The invention relates to the technical field of rigid-flex boards, in particular to a surface cleaning device for rigid-flex boards. Background technique [0002] Rigid-flex boards are flexible circuit boards and rigid circuit boards, which are combined according to relevant process requirements after pressing and other processes to form a circuit board with FPC characteristics and PCB characteristics. It can be used for some products with special requirements. Among them, there are both a certain flexible area and a certain rigid area, which is of great help to save the internal space of the product, reduce the volume of the finished product, and improve the performance of the product. The production rate is low, the input materials and manpower are more, therefore, its price is more expensive, and the production cycle is longer; the electronic engineer draws the circuit and shape of the flexible board according to the demand, and then sends it to the...

Problems solved by technology

[0002] Rigid-flex boards are flexible circuit boards and rigid circuit boards, which are combined according to relevant process requirements after pressing and other processes to form a circuit board with FPC characteristics and PCB characteristics. It can be used for some products with special requirements. Among them, there are both a certain flexible area and a certain rigid area, which is of great help to save the internal space of the product, reduce the volume of the finished product, and improve the performance of the product. The production rate is low, the input materials and manpower are more, therefore, its price is more expensive, and the production cycle is longer; the electronic engineer draws the circuit and shape of the flexible board according to the demand, and then sends it to the production of the flexible board. After the CAM engineers process and plan the relevant documents, and then arrange the FPC and PCB production lines required for the FPC production line to produce PCBs, after these two soft boards and hard boards come out, according to the planning requirements of the electronic engineer, the FPC It is seamlessly laminated with the PCB through a laminating machine, and the soft and hard board is used in mobile phones, keypads and side buttons, computers and LCD screens, motherboards and displays, etc.

[0003] However, in the prior art, a small amount of dust and impurities will adhere to the surface of the flexible circuit board and the rigid circuit board. If the surfaces of the two circuit boards are not cleaned in time, the surface of the circuit board will be damaged during the process of pressing the two. Cause damage and reduce product quality, so we need to propose a board surface cleaning device for soft and hard bonded boards
