A kind of holding mechanism used on the pcb board furnace carrier

Abstract

The invention discloses a pressing and holding mechanism used on PCB stove-passing carriers, comprising a pressure plate, a convex block, a T-type pressure rod, a nut, an I-shaped pressure block, a fixing stud, a retaining disk, a guide rod, a pressure spring, washers, and the like. The convex block is arranged on the pressure plate, and a clamping slot is arranged in the convex block. Through clamping fit between the clamping slot and a clamping strip on the I-shaped pressure block, the pressure plate can be rotated. The fixing stud is driven to rotate by rotating the I-shaped pressure block, so that the fixing stud can be screwed into a threaded hole in a stove-passing carrier. Thus, the whole pressing and holding mechanism can be rotated and positioned, a PCB can be pressed and clamped easily, and the service life of the whole device is prolonged. A positioning slot is arranged on the pressure plate. The position of the T-type pressure rod can be adjusted according to PCBs of different sizes and fixed by the nut. Thus, the pressing and holding mechanism can meet the requirement for pressing and holding operation on PCBs of different sizes, and is of wide applicability. The device has the advantages of simple structure, convenient operation and high practicability, and is suitable for large-scale production and use.

Description

Technical field: [0001] The invention belongs to the technical field of furnace passing carriers, and in particular relates to a pressing and holding mechanism for a PCB board furnace passing carrier. Background technique: [0002] With the development of the electronic technology industry, the assembly of electronic products is developing towards high density, high precision, automation, miniaturization and low cost. Among related technologies, surface mount technology is a new generation of electronic assembly technology that adapts to technological development. In SMT production, in order to save costs, people usually design the printed circuit board (PCB) of electronic products as a single board without board edges. During SMT printing and placement, precise positioning cannot be performed, resulting in the inability to achieve accurate printing. patch. In order to solve the problem that the PCB board cannot be accurately printed and mounted, it is usually used to make...

Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is that in the prior art, the fixed end of the pressure rod used for the furnace carrier needs to be tightened for a long time, which is easy to cause slippage, and then leads to damage to the furnace carrier, thus proposing a Used for the holding mechanism on the PCB board furnace carrier
