Description

Towable Tray Mobile Equipment

The invention relates to a device, in particular to a towed pallet moving device.

Due to the development of science and technology, various electronic products can be seen everywhere. These electronic products mainly rely on the operation of circuit boards to produce various functions. Although circuit boards have different designs according to different uses and functions, they are usually made of various electronic components and circuit configurations.

Common electronic components include resistors, capacitors, and inductors. After the electronic components are manufactured, a series of testing stations are required to ensure the quality of the electronic components. For example, after the capacitor is manufactured, it is necessary to conduct appearance inspection, long and short leg position inspection, electrical test, environmental test, baking inspection, charging inspection, electrolyte activation inspection, static inspection, parameter inspection and other inspection items. Different testing items are carried out by different testing stations, and different testing stations are usually connected by some equipment with mobile functions, such as rails. In practice, electronic components will be placed on a tray to facilitate transportation between different inspection stations.

Please refer to the first figure to the fourth figure, wherein the first figure shows the schematic diagram of the pallet leaving the first inspection station in the prior art; the second figure shows the schematic diagram of the pallet entering the rotary table in the prior art; the third figure is A schematic diagram showing the rotation of the rotary table in the prior art; and, the fourth figure is a schematic diagram showing the tray in the prior art entering the second inspection station and the rotary table resets. As shown in the figure, a pallet moving device PA1 includes a detection platform PA11 and a rotary table PA12 for moving a pallet PAT, wherein the pallet PAT is used for carrying electronic components.
