Description

Technical Field

[0001] The utility model relates to the technical field of FPCB soft circuit board processing, in particular to a FPCB soft circuit board suction nozzle. Background Art

[0002] FPCB (flexible printed circuit board) nozzle technology is usually used in the process of sucking and fixing flexible circuit boards to ensure stability and precision during the manufacturing and assembly process. The nozzle technology can help ensure the correct position of the FPCB on the production line for subsequent processing and assembly work. At present, in the manufacturing process of FPCB soft circuit boards, nozzles are usually required for auxiliary work. The nozzle parts are usually formed in one piece. After the nozzle absorbs the electronic components and moves them to the required position, they are placed. If the placement pressure state is too large, it will directly cause different degrees of damage to the electronic components. Usually, buffering treatment will be adopted, but the spring used for buffering will gradually weaken its elastic effect as the use time goes by, which will lead to the situation that the corresponding effect cannot be achieved. At the same time, the fixed end part of the FPCB soft circuit board nozzle cannot be effectively matched according to the fixed seat part of the equipment, resulting in the situation that it cannot be installed, thereby reducing the versatility of the FPCB soft circuit board nozzle and affecting the use effect of the FPCB soft circuit board nozzle.

[0003] Therefore, it is necessary to develop a FPCB soft circuit board suction nozzle. Utility Model Content

[0006] A pressure seat is installed below the suction nozzle seat.

[0007] Preferably, a suction nozzle is installed at the bottom center of the suction nozzle seat, and an airway A is opened at the inner center of the suction nozzle.

[0008] Preferably, a threaded head is provided at the center position of the bottom end of the gas guide fixing head, the outer wall of the threaded head is threadedly connected to the inner wall of the threaded hole, and an airway B is opened at the inner center position of the gas guide fixing head.

[0009] Preferably, a protective pad is provided at the bottom of the pressure seat, and a fixing seat is installed below the outer walls on both sides of the pressure seat.

[0012] Preferably, a spring is provided below the outer wall of the guide column, and the spring is located between the nozzle seat and the fixing seat.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The air guide fixing head is installed in the threaded hole on the nozzle seat by a threaded connection method through a threaded head, and the pressure seat is connected to the mounting hole on the nozzle seat by a guide column in a sliding manner. The spring on the outer wall of the guide column has an elastic reaction force and a buffering effect. When the nozzle adsorbs electronic components for installation, the pressure seat cooperates with the spring to take buffering measures, thereby reducing the damage to the electronic components caused by excessive pressure on the nozzle. At the same time, the reaction force of the spring also facilitates the installation of electronic components on the FPCB soft circuit board.

[0015] The pressure seat is detachable to facilitate replacement of the spring, and the situation in which the elasticity of the spring is weakened due to long-term use is avoided as much as possible.
