[0036] The transmission seat 3 is provided with a width adjustment component for adjusting the distance between the fixed seat 4 and the movable seat 6;

[0037] The fixed seat 4 is provided with a first mounting block 41; the movable seat 6 is provided with a second mounting block 61; the flexible feeding device of the PCBA automatic testing equipment also includes a carrier 7; the carrier 7 is detachably connected to the first mounting block 41 and the second mounting block 61 respectively.

[0038] Specifically, the flexible loading device of the PCBA automatic testing equipment described in this embodiment, when transmitting the PCBA board 11 with burrs, first disassembles the carrier 7, so that the PCBA board 11 with burrs can be directly transmitted between the first transmission component and the second transmission component, and the transmission between the first transmission component and the second transmission component has a stable transmission speed and a large carrying capacity.

[0039] When the burr-free PCBA board 12 is transmitted, since there are electronic components at the edge of the burr-free PCBA board 12, it cannot be directly placed between the first transmission component and the second transmission component. Therefore, the distance between the fixed seat 4 and the movable seat 6 is adjusted by the width adjustment component, and then the carrier 7 is installed on the first mounting block 41 and the second mounting block 61, and then the burr-free PCBA board 12 is placed on the carrier 7, which has the characteristics of stable bearing and precise positioning, ensuring the transmission accuracy of the burr-free PCBA board 12.

[0040] After the burred PCBA board 11 or the burr-free PCBA board 12 is placed on the transmission seat 3, it is driven to the automatic testing equipment for loading through the entry and exit module 2, wherein the entry and exit module 2 can be a motor screw structure, a cylinder oil cylinder structure or a linear module, etc.

[0041] This embodiment can select the most suitable feeding method according to the characteristics of the product itself; for products with burrs, the first transmission component and the second transmission component are used for transmission; for products without burrs, the width adjustment component is first used for adjustment, and then the carrier 7 is used for transmission. The versatility of the feeding device is greatly improved, and it can easily adapt to a variety of different feeding methods. In addition, it can significantly improve production efficiency and effectively reduce production costs. Secondly, it can also greatly simplify the operation process and improve the stability of the production process.
