Background

It is known that in the SMT industry, many products (or workpieces) such as PCB boards are mostly processed by a double-sided process with A, B sides, such as: the processing technologies of marking, code spraying, marking, labeling, carving, cutting, welding, dispensing, detecting and the like; in this process, the operation of turning the board over the product is an indispensable operation step. In the prior art, the plate turnover operation of a product is completed by adopting the following two modes:

1. the plate turning operation of the product is finished by an external plate turning machine, namely: connecting two pieces of process treatment equipment by using an external panel turnover machine to form a flow production line; the product is conveyed to a designated operation area of the process treatment equipment at the front stage in the form of the surface A, after the process treatment equipment finishes the process treatment of the surface A of the product, the product is conveyed to an external plate turnover machine for plate turnover, then the product is conveyed to the designated operation area of the process treatment equipment at the rear stage in the form of the surface B, and after the process treatment equipment finishes the process treatment of the surface B of the product, the product is output. This method requires high equipment and site investment cost, management and maintenance cost, and the like, and the economic benefit is not significant.

The flap frame assembly 100 is primarily used as a carrier for the flap mechanism to perform a 180 degree turning motion, and is disposed within the work area of the work machine (e.g., the area below the work head); the plate turnover frame device 100 is a frame structure similar to a square shape and mainly composed of a workpiece feeding frame arm 110, a first positioning frame arm 120, a workpiece discharging frame arm 130 and a second positioning frame arm 140 which are sequentially connected end to end; wherein, an auxiliary rotating shaft 150 is provided at an outer center region of the second positioning frame arm 140.

The workpiece holding device 200 is mainly used for holding and fixing two opposite edges of a workpiece a (in this embodiment, the workpiece a is represented by a PCB) conveyed into the flap frame device 100 through the workpiece feeding frame arm 110, so as to ensure that the workpiece a does not move or slide off during the process of being processed or being turned; the workpiece clamping device 200 includes a first clamp 210 disposed inside the first positioning frame arm 120 and a second clamp 220 disposed inside the second positioning frame arm 140, wherein the first clamp 210 and the second clamp 220 are disposed in parallel and opposite to each other, so that the first clamp 210 and the second clamp 220 clamp and fix the edge of the workpiece a.

The rotation driving device 300 is mainly used for driving the flap frame device 100 to rotate around the auxiliary rotating shaft 150 as an axis, for example, a workpiece a clamped and fixed in the flap frame device 100 is turned 180 degrees and changed from a front side to a back side, so that a working head of the working machine can perform process treatment on the surface of the workpiece a; the rotation driving device 300 includes a rotation driver 310 disposed at an outer side of the first positioning frame arm 120 and a bearing support 320 disposed at an outer side of the second positioning frame arm 140; wherein, the rotating shaft of the rotating driver 310 is fixedly connected with the outer central area of the first positioning frame arm 120, and the body of the rotating driver 310 is fixed on the body fixing device 500; the bearing support 320 is fixed on the mechanism fixing device 500 and rotatably sleeved with the auxiliary shaft 150, and the rotary driver 310, the bearing support 320 and the auxiliary shaft 150 are coaxially distributed.

In some embodiments, the positions and the number of the electromagnetic attractors 420 and the limit baffles 410 can be changed, for example, the limit baffles 410 are disposed at four corners of the flap frame device 100, and two electromagnetic attractors 420 are disposed on the mechanism fixing device 500 to be approximately distributed diagonally.

The material guide connection device 800 is arranged on the feeding end side and the discharging end side of the turnover frame device 100 and is mainly used for conveying the workpiece a into the turnover frame device 100 or outputting the workpiece a from the turnover frame device 100; in this embodiment, the material guiding and connecting device 800 is integrated with other related devices through the mechanism fixing device 500; in other embodiments, the material guiding connection device 800 may be disposed only on the feeding end side or the discharging end side of the flap frame device 100, or may not be disposed according to the practical application of the flap mechanism; in addition, in some embodiments, the material guiding and connecting device 800 may also be a workpiece conveying mechanism of the working machine itself or a separately configured conveying mechanism.
