Description

Plate rack conveying method

The invention relates to a conveying method, in particular to a conveying method of a plate rack.

In the process of making a circuit board, it is necessary to dry the printed material on the circuit board through a drying operation. In the current existing technology, when the circuit board is baked, the circuit board is first placed on a board rack. The board holder has a plurality of clamps to clamp the sides of the circuit board. Then place the board rack on the conveyor mechanism of the oven, and drive the board rack and the circuit board into the oven for drying. After drying, the circuit board is separated from the board rack, and the board rack passes through a recycling and conveying mechanism in the oven. Move to the entrance of the oven to combine with the unbaked circuit board. The conveying mode of the plate rack and circuit board in the oven can be roughly divided into two modes: horizontal conveying and vertical conveying. Horizontal conveying can improve the conveying efficiency, but the space utilization rate inside the oven is low, which means that more circuit boards cannot be baked at the same time. The vertical conveying can effectively improve the space utilization rate inside the oven, so that the oven can bake a large number of circuit boards at the same time, but the conveying speed is much slower, making the work efficiency poor. Therefore, there is room for improvement in the above two methods.

Therefore, the object of the present invention is to provide a pallet conveying method that improves the aforementioned problems.

The pallet conveying method of the present invention is executed by a conveying system of a machine, the machine further includes a body having an entrance and an exit opposite to the entrance, and the conveying system includes an entrance provided at the entrance A feeding device, a first conveying device arranged in the body, a second conveying device arranged in the body below the first conveying device, and a discharging device arranged at the outlet, the feeding device having An entrance turnover mechanism. The method for conveying a plate rack includes the following steps: providing a plate rack, placing the plate rack on the second conveying device in a state extending along a horizontal direction, and the second conveying device conveying the plate rack To the inlet turning mechanism of the feeding device; the inlet turning mechanism turns the plate rack from a state extending along the horizontal direction to a state extending along a vertical direction; an inlet capturing mechanism of the feeding device captures Take a workpiece and combine the workpiece with the plate rack; a feeding mechanism of the feeding device conveys the plate rack in a state extending along the vertical direction together with the workpiece into the machine body; the first conveying device The pallet is conveyed to an outlet turning mechanism of the discharging device in a state of extending along the vertical direction together with the workpiece; the outlet turning mechanism turns the pallet from the state extending along the vertical direction to being along the The state extended in the horizontal direction; an outlet capturing mechanism of the discharging device captures the workpiece to separate the workpiece from the plate rack; and the plate rack is conveyed to the second conveying state in a state extending along the horizontal direction Device.

In some embodiments, the plate frame has a plurality of clamps for clamping the workpiece, and before the workpiece is combined with the plate frame, a first clamping mechanism of the feeding device presses the clamps against the clamps. The clamps are opened. After the entry picking mechanism places the workpiece on the plate rack, the first clamping mechanism moves away from the clamps so that the clamps are clamped again to clamp and fix the workpiece, completing the workpiece and the Combination of plate frame.

In some embodiments, the plate frame has a plurality of clamps for clamping the workpiece, and before separating the work piece from the plate frame, a second clamping mechanism of the discharging device presses the clamps against the clamps. The clamps are opened, so that the exit picking mechanism can pick up the workpiece away from the plate frame and separate the workpiece from the plate frame.

In some embodiments, after the inlet turning mechanism turns the plate frame, it further includes a step of lifting the plate frame, and a lifting mechanism of the feeding device will drive the plate frame to move upward to separate the plate frame from the inlet turning mechanism.

In some embodiments, in the step of conveying the pallet to the second conveying device, a descending mechanism of the discharging device drives the pallet to move downward to a position connected to the second conveying device and to the second conveying device. On the return mechanism with the same level of the two conveying devices, the return mechanism conveys the plate rack to the second conveying device.

The present invention has at least the following effects: through the entrance turning mechanism, the plate frame can be converted from a state extending along a horizontal direction to a state extending along a vertical direction, and then the plate frame together with the workpiece can be transferred through the feeding mechanism Transported to the machine body for drying operation, the plate rack and the workpiece are transported to the exit turnover mechanism through the first conveying device to leave the machine body to complete the drying operation, and then the plate shelf is converted to the edge by the outlet turnover mechanism In the horizontally extended state, after separating the workpiece from the plate rack, the plate rack is finally transported to the second conveying device, and the second conveying device can send the plate rack book to the entrance turning mechanism to form A conveying cycle. Through the above process, the conveying method of the plate rack on the second conveying device can be horizontal conveying to obtain the advantage of improving the conveying efficiency, but the plate rack is combined with the workpiece by turning over before entering the machine body. Entering the body by vertical conveying also has the advantage of improving the space utilization rate inside the body, enabling the body to bake a large number of circuit boards at the same time, which means that it has the advantages of both horizontal and vertical conveying methods. , So that the overall process strikes a balance between the conveying efficiency and the space utilization rate of the machine, and has been improved to a considerable extent.
