The two sets of tray grabbing components 135 are respectively arranged on two sides of the first detection component 115 and the second detection component 116, so that the tray grabbing components 135 can grab and move the trays 170 on two sides of the first detection component 115 and the second detection component 116 without crossing the first detection component 115 and the second detection component 116.
The first detection assembly 115 is used for shooting from above the tray 170, after the chip 180 is mounted on the tray 170 and moves to the lower part of the moving path of the second transfer mechanism 114, the first detection assembly 115 moves onto the tray 170 and is limited by the limitation of the lens field range, the first detection assembly 115 is set to have a larger field range, and a single shot image can include more chips 180, so that the information of the chips 180 shot by the first detection assembly 115 can be preliminarily analyzed, and further the number of the chips 180 in each row and each column on the tray 170 and the condition of whether vacant positions exist for not placing the chips 180 can be obtained, and the information is used for planning the shooting path of the second detection assembly 116.
The second detection assembly 116 is also used for shooting from above the tray 170, except that after the chip 180 is mounted on the tray 170 and moves to the lower part of the moving path of the second transfer mechanism 114, the second detection assembly 116 moves onto the tray 170 and shoots one by one according to the moving path of the second detection assembly 116 planned by the first detection assembly 115 according to the acquired chip 180 information, so that a clearer image of the chip 180 is shot each time through the second detection assembly 116, meanwhile, shooting of empty positions by the second detection assembly 116 is avoided, deviation of detection data output is reduced, unnecessary shooting operation is avoided, a shorter moving path is obtained, and the whole detection operation efficiency is improved.

It should be noted that the area where the chips 180 are loaded on the tray 170 may be divided into three primary areas 172, and the flat plate on which the chips 180 are placed is placed in the primary area 172, because the sizes and specifications of the chips 180 are not consistent, the flat plate in the three primary areas 172 may be used as a standard specification reference, and the chips 180 with different specifications may be placed on the flat plate at different densities, so that the tray 170 and the flat plate may have universal and relatively fixed sizes, and further, the placement density of the chips 180 on the flat plate may reasonably adapt to different specifications of the chips 180, however, because the sizes and specifications of the chips 180 are different, the chips 180 need to be repositioned in the following detection processes, such as grabbing, detection and the like, so as to ensure that the chips 180 to be detected may be accurately grabbed and effectively detected, and after the first detection assembly 115 shoots and positions the primary areas 172 on the tray 170, the quantity information of the chips 180 in the primary areas 172 is obtained.
Then, with the continuous operation of the displacement assembly 130 of the second transfer mechanism 114, the first detection assembly 115 is removed from the tray 170 containing the chips 180, the space required for the movement of the second detection assembly 116 is provided, and then the second detection assembly 116 moves onto the tray 170 containing the chips 180, and the chips 180 on the tray 170 are detected again by the second detection assembly 116.

The longitudinal lifting device 138 is used to drive the third detecting component 221, the fourth detecting component 222, or the fifth detecting component 223 toward or away from the third platform region 192, so as to achieve the purpose of focus adjustment when detecting the chip 180 on the turntable 200.
Since the sizes and the sizes of the chips 180 to be detected cannot be kept uniform, the chips 180 within a certain size range can be covered by the field of view of the third detecting component 221, the fourth detecting component 222 and the fifth detecting component 223, that is, after the longitudinal heights of the third detecting component 221, the fourth detecting component 222 and the fifth detecting component 223 are adjusted by the longitudinal lifting device 138, the chips 180 can be covered and detection shooting without missing can be realized, but if the chips 180 to be detected are large, the third detecting component 221, the fourth detecting component 222 and the fifth detecting component 223 cannot realize single shooting.
The driving path of the first adjusting part 261 on the third platform region 192 is perpendicular to the driving path of the second adjusting part 262 on the third platform region 192, so that the first adjusting part 261 and the second adjusting part 262 are formed to drive the third detecting component 221, the fourth detecting component 222 or the fifth detecting component 223 to move on the third platform region 192, and further the third detecting component 221, the fourth detecting component 222 or the fifth detecting component 223 can perform region shooting on the chip 180 on the detecting turntable 200, and after the images shot by multiple additional regions are spliced by a processing system, a complete shot image is formed, and the applicability of detection on chips 180 with different specifications is improved.
