Circuit board fixing and overturning device not prone to falling off

Abstract

The invention relates to the technical field of circuit board processing and production equipment, and discloses a circuit board fixing and overturning device not prone to falling off. The circuit board fixing and overturning device comprises a machine body, a transmission belt is slidably connected to the inner wall of the front face of the machine body, a rolling plate is fixedly installed on the surface of the right side of the machine body, and a placing plate is fixedly installed on the surface of the front face of the rolling plate; and fixing assemblies are fixedly installed at top and bottom of the front face of the right side of machine body correspondingly. According to the circuit board fixing and overturning device not prone to falling off, after a sliding block is stressed to be separated from a fixing block, a rolling wheel slides on the inner wall of a top box to make contact with an intercepting column, and the intercepting column drives a piston rod to slide on the inner wall of a negative pressure rod; a negative pressure rod is extruded to drive a push rod to move towards the outer side, the push rod collides with a rotating plate, the rotating plate is stressed to rotate through a torsional spring, then the right side of the top of the rotating plate drives a telescopic rod to move towards the hollow boxes through a guide rod, at the moment, the middle of the circuit board is just located at the crack of the two hollow boxes, and then the hollow boxes clamp the circuit board.

Description

technical field [0001] The invention relates to the technical field of circuit board processing and production equipment, in particular to a circuit board fixing and turning device that is not easy to fall off. [0002] technical background [0003] Circuit boards are also called PCB boards, ceramic circuit boards, high-frequency boards, impedance boards, etc. Circuit boards make circuits miniaturized and intuitive, and play an important role in mass production of fixed circuits and optimizing the layout of electrical appliances. Soldering and other processes combine the relevant process requirements together to form a rectangular FPC circuit board. In the process of circuit board production and processing, it is often mass-produced. During the production process, the rotating board is turned over for processing and production. [0004] However, the general circuit board often has the following two defects during the flipping process: [0005] 1. Most of the circuit boards o...

Problems solved by technology

[0005] 1. Most of the circuit boards often use a side column to move down or use clips to change the processing surface of the circuit board when they are reversed. Using the side column to move often causes the circuit board to fall off during the movement, resulting in a processed circuit. The board will be damaged by collision;

[0006] 2. If clamps are used for refueling and flipping work, because the material of the circuit board is plastic, its strength is low. If the clamping force is too large, it will cause damage to the inside of the circuit board, and seriously cause the edge of the circuit board to break. If the holding force is too small, there will be a state of dry running during the clamping process, that is, the circuit board cannot be effectively driven to turn over;
