The vacuum suction unit 74 communicates with the groove. After the camera module is placed into the groove, the camera module is enabled to be more smooth through the negative pressure adsorption of the vacuum adsorption unit 74. In addition, whether the camera module is arranged in the groove can be judged through the pressure value change of the vacuum adsorption unit 74. It is determined by the pressure value change of the vacuum suction unit 74 that the camera module is placed in the groove, and the upper cover 722 of the clamp 72 is closed after a preset time interval.

In this embodiment, a gripper module 7 includes two grippers 72. The jig module 7 is provided with a plurality of jigs 72, and the apparatus volume and the apparatus cost can be reduced.
Since the plurality of clamps 72 of the same clamp module 7 are in a same-motion relationship, one clamp module 7 simultaneously clamps the plurality of camera modules to move. If some camera modules are unqualified in the plurality of camera modules clamped by the clamp module 7, the camera modules which are determined to be unqualified do not participate in the subsequent process, and the rest camera modules continue to complete the subsequent process to obtain the qualified camera modules. If the plurality of camera modules clamped by the clamp module 7 are all determined to be unqualified, the clamp module 7 clamps the plurality of camera modules, subsequent processes are not carried out, and the camera modules directly return to the initial positions.
For example, the clamp module 7 clamps A, B two camera modules, the process is N processes, m is less than or equal to N, that is, if the camera module a detects a failure in the process m, the camera module a in the subsequent N-m processes does not participate, the camera module B continues the subsequent N-m processes, and the clamp module 7 does not return to the initial position until the camera module B detects a failure or all the detection/processing processes are completed.
Alternatively, when there are a plurality of camera modules in the jig module 7, it is designed according to the production efficiency calculation that the jig module 7 is returned to the start position when how many of the plurality of camera modules are detected as being defective.
According to an alternative solution of the present application, the number of gripper modules 7 is multiple. The plurality of jig modules 7 are arranged in parallel, and the plurality of jig guide rails extend in the X direction. Each clamp module 7 may include a plurality of clamps 72, thereby greatly improving the working efficiency of the focusing and dispensing apparatus of the present application. The focusing dispensing apparatus of the present embodiment includes four clamp modules 7.
