Description

A turn over board conveying equipment for circuit board Technical Field The invention relates to the field of plate conveying and turning equipment, in particular to turning plate conveying equipment for a circuit board. Background The PCB turnover machine is special equipment in an electronic manufacturing production line, and is mainly used for realizing 180-degree automatic turnover of a double-sided PCB (printed circuit board) or a PCBA (circuit board assembly with attached elements) so as to meet the double-sided processing requirement; However, in the movement process of the panel turnover equipment, the PCB board can slide off from the conveying channel under the action of gravity, In order to solve the problem, in the prior art, active clamping type panel turnover equipment ‌ is adopted, namely, pneumatic/electric clamping jaws are adopted to fix a panel, but a ‌ connecting piece ‌ such as a gas pipe and a cable which are required to be driven is required to rotate along with the equipment, and the connecting piece is easy to wear and break due to ‌ torsional fatigue ‌ under high-frequency reciprocating motion, so that clamping failure and equipment shutdown are caused; ‌ and another elastic blocking type panel turnover device is to drive a blocking piece to restrict a board through a spring/torsion spring, however, elastic fatigue ‌ of ‌ is very easy to occur under long-term high-frequency action of an elastic element, so that elastic attenuation, reset misalignment or unstable positioning of the blocking piece are caused, and the PCB is caused to slide or scratch the surface. Disclosure of Invention The invention aims to provide a turnover plate conveying device for a circuit board, which solves the problem that the prior art cannot reliably and effectively limit and block a rotating PCB. The invention adopts the following technical scheme that the turnover plate conveying equipment for the circuit board comprises a conveying component capable of rotating around the geometric center of the conveying component, wherein the conveying component is provided with a conveying channel for driving a plate to move, and one side of the conveying channel is provided with a blocking component; The blocking part comprises a blocking part connected with the conveying component and guide rails with two ends provided with a limiting bending groove in advance, and any limiting bending groove is in sliding clamping connection with the blocking part; when the conveying assembly rotates, the blocking piece is driven to be separated from the limiting bent groove, and when the blocking piece is extruded by the guide rail, the blocking piece rotates towards the conveying channel and protrudes out of the conveying channel. Compared with the prior art, the device has the advantages that the blocking piece of the device entirely blocks and restrains the triggering and the restraint of the reset action, the physical limit and the extrusion of the ‌ blocking piece ‌ are conducted through the geometric shape of the ‌ guide rail ‌, no elastic piece ‌ is needed to be used in ‌, and the potential reliability hazard that the elastic piece works by using the elastic piece and fails due to fatigue in the prior art is avoided; in addition, in the whole working process ‌ of the device, no pneumatic or electric driving device is required to be added for the blocking piece ‌, so that the problem of twisting abrasion and breakage of the connecting piece caused by rotation of the conveying component is fundamentally avoided; ‌ and no separate electrical control logic, sensors or drive units are required for the barrier and the guide rail, the device structure is greatly simplified, and the manufacturing cost and the maintenance complexity are reduced.
