When material loading subassembly 10 is used for check out test set, can effectively reduce check out test set's width in the second direction, and material loading subassembly 10 and transfer module 20 can all locate check out test set's box 50, in the second direction, one side of box 50 of keeping away from material loading subassembly 10 can be equipped with the window in order to be used for observing, overhaul etc., because second material loading platform 3 and first material loading platform 2 are suitable for being located transfer module 20 at the homonymy of second direction, and then be convenient for effectively reduce the distance between window and the transfer module 20 on the box 50, effectively promoted operating personnel and carried out the convenience of overhauing etc. to transfer module 20 through the window, the maintenance of check out test set has been made things convenient for.

The second feeding table 3 can move to a predetermined position relative to the first feeding table 2, so that the to-be-detected piece on the second feeding table 3 is conveyed to the first feeding table 2. For example, the second feeding table 3 may be movable between a second loading position and a predetermined position, in the second loading position, the piece to be detected may be conveyed to the second feeding table 3 by a conveying mechanism or by an operator, the second feeding table 3 drives the piece to be detected to move to the predetermined position, and the piece to be detected may be transferred from the second feeding table 3 to the first feeding table 2.

It will be appreciated that, in the predetermined position, the second feeding table 3 and the first feeding table 2 are relatively movable in a first direction to transfer the pieces to be inspected on the second feeding table 3 to the first feeding table 2. For example, when the second feeding table 3 moves to a predetermined position, the second feeding table 3 may remain stationary relative to the frame 1, and the first feeding table 2 may move in a first direction relative to the frame 1, so that the first feeding table 2 may take away the to-be-detected piece on the second feeding table 3; for another example, when the second loading table 3 moves to the predetermined position, the first loading table 2 may remain stationary with respect to the frame 1, and the second loading table 3 may move in the first direction with respect to the frame 1, so that the object to be inspected on the second loading table 3 may be transferred to the first loading table 2.

The following description will be given taking the first direction as the up-down direction as an example: as shown in fig. 3-6, when the second feeding table 3 moves to a predetermined position (as shown in fig. 6), the second feeding table 3 can remain stationary relative to the frame 1, and the first feeding table 2 can move upward to take away the object to be detected on the second feeding table 3; alternatively, when the second feeding table 3 moves to the predetermined position, the first feeding table 2 may remain stationary with respect to the frame 1, and the second feeding table 3 may move downward, so that the to-be-detected object remains on the first feeding table 2 and is separated from the second feeding table 3 due to the blocking action of the first feeding table 2.

In some embodiments, as shown in fig. 5 and 6, the second feeding table 3 can move along the conveying direction, so that the second feeding table 3 has a simple movement mode, which is beneficial to simplifying the structure of the feeding assembly 10; moreover, because the moving direction of second material loading platform 3 is perpendicular with the moving direction of first material loading platform 2, be convenient for guarantee to detect the piece from second material loading platform 3 conveying to the in-process of first material loading platform 2 wait to detect the posture of placing of piece remain unchanged all the time, avoid waiting to detect the piece because of receiving external force to take place to deflect etc. at above-mentioned in-process, influence the detection accuracy that detects the piece, can avoid detecting the piece and receiving frictional force, avoid detecting the piece fish tail that detects in addition.

For example, in the example of fig. 1 and 2, the two ends of the conveying assembly 20 in the conveying direction are respectively a first end and a second end, the first feeding table 2 is adapted to be arranged at the first end of the conveying assembly 20, the second feeding table 3 moves between a second loading position and a preset position, and in the second loading position, the second feeding table 3 and the conveying assembly 20 are arranged in a staggered manner in the conveying direction, so that the second feeding table 3 extends to the side of the first end away from the second end, the occupied amount of the conveying assembly 20 in the peripheral space of the second feeding table 3 can be reduced, and the peripheral space of the second feeding table 3 can have enough operating space to quickly load materials to the second feeding table 3.

It will be appreciated that in the second loading position, the offset distance of the second loading table 3 from the transfer assembly 20 in the transfer direction can be specifically set according to actual requirements.

Of course, the movement manner of the second feeding table 3 is not limited thereto. For example, the second loading table 3 may also be pivotally connected to the frame 1, the second loading table 3 being rotatable between a second loading position and a predetermined position.
