Description

Technical Field

[0001] The utility model relates to the technical field of AOI detection devices, in particular to an AOI detection device for an SMT production line. Background Art

[0002] AOI inspection equipment, also known as optical automated inspection (AOI) equipment, has become a crucial tool for ensuring product quality and controlling process quality in the electronics manufacturing industry. The general process for AOI inspections is similar, often using pattern recognition. This involves comparing a standard digitized image stored in the AOI system with the actual image being inspected to determine the inspection result. AOI equipment is widely used in SMT production lines.

[0003] Chinese patent publication number CN220772956U discloses an AOI inspection device for an SMT patch production line, comprising an inspection component, a first-direction drive component, and a second-direction drive component. The first-direction drive component is disposed on the second-direction drive component, and the inspection component is disposed on the second-direction drive component. The inspection component comprises a fixed block b, a connecting bracket, and a camera, the camera being fixed to the fixed block b, one end of which is fixed to the connecting bracket. A mounting plate is provided with an escape slot, through which a slider of a first screw member is connected to the connecting bracket. The second-direction drive component drives the first-direction drive component to move in the second direction, and the first-direction drive component then drives the inspection component in the first direction, thereby achieving horizontal movement of the camera. This improves the cost of the AOI inspection device, which requires multiple cameras to repeatedly capture and inspect multiple areas of a printed circuit board.

[0004] The AOI inspection device of the existing SMT patch production line moves the inspection and shooting camera through a drive member and a screw rod. However, the first square drive component is easily restricted by the movement of the mounting plate opening during the moving operation, resulting in a reduced movement range. At the same time, the first and second drive components have complicated structures and a certain weight, and they shake during movement, which affects the inspection work and reduces the inspection efficiency.

The driver is mounted on side plates 202, and the driver end moves along the opening. The opening in mounting plate 203, which accommodates the driver and mounting bracket 4, is provided along mounting plate 203. This opening increases the range of the driver's movement, improving the usability of the AOI inspection device on the SMT production line.

[0032] Further explanation: the driving part includes a motor b204, a screw rod b205, a fixed block b206, a guide rod 207, and a guide block 208.
