Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and in particular relates to a transmission inspection device for a chip mounter. Background Art

[0002] The placement machine, also known as the "mounting machine", is a device that accurately places surface mount components on the PCB board by moving the placement head in the production line. After the components are mounted on the PCB board, they are conveyed to the inspection device in the online Aoi inspection equipment through a conveyor. The inspection device is installed in the online Aoi inspection equipment. The PCB board conveyed to the back is photographed and inspected by the high-speed camera on the inspection device to check whether the PCB board patch is qualified.

[0003] When the existing SMT equipment transmission inspection device is in use, the nut seat two in the mobile cross frame moves up and down on the left screw rod, thereby causing the high-speed camera to move up and down, and the nut seat one in the mobile cross frame moves left and right under the action of the right screw rod, driving the high-speed camera to move left and right, thereby adjusting the up and down, left and right positions of the high-speed camera, which is convenient for inspecting the PCB board. However, during use, the left and right screw rods are exposed to the outside, and some foreign matter is easy to fall on the outer walls of the left and right screw rods. If they are not cleaned in time, more and more foreign matter will be attached. When the nut seat one moves left and right on the right screw rod, the foreign matter will wear the right screw rod. When the nut seat two moves on the left screw rod, it will wear the left screw rod, reducing the service life of the left and right screw rods. For this reason, we propose a SMT equipment transmission inspection device. Utility Model Content
