The feeding device includes a base, a first picking mechanism and a second picking mechanism. The first picking mechanism is arranged on the base and used for picking and placing the workpiece, and the second picking mechanism is arranged on the base and used for picking and placing the protective part. The above feeding device utilizes the first picking mechanism to pick and place the workpiece accommodated in the protective part, and can utilize the second picking mechanism to pick and place the protective part after removing the workpiece. The same feeding device can realize picking and placing both the workpiece and the protective part, which is beneficial to simplifying the structure of the feeding device and improving the picking and placing efficiency.

In some of the embodiments, the base includes a first fixed plate and a second fixed plate perpendicular to the first fixed plate, the first picking mechanism is connected with the first fixed plate, and the second picking mechanism is connected with the second fixed plate. In this way, a space utilization rate of the base can be increased.

In some of the embodiments, the first picking mechanism includes at least two first picking and clamping jaws, all the first picking and clamping jaws are distributed side by side in a first direction and have an adjustable distance in the first direction, and the first direction is a width direction of the workpiece. In this way, the distance between the first picking and clamping jaws in the first direction can be adjusted, and when the plurality of workpieces are distributed side by side in the first direction, the first picking mechanism can simultaneously pick and place the plurality of workpieces at one time, thereby greatly improving the picking and placing efficiency of the workpieces.

In this way, the first driving part is utilized to drive the track plate to move, so as to drive all the first picking and clamping jaws to move in the first direction. The different positions of the guide wheels in the sliding grooves will result in different distances between the first picking and clamping jaws, thereby making operation convenient.

According to some embodiments of the present application, please refer to FIG. 4 and FIG. 1, in the first direction, a dimension L2 of the probe rods 420 is greater than or equal to a dimension L1 of the protective part 10.

It can be understood that, in the first direction, if the dimension L2 of the probe rods 420 is smaller than the dimension L1 of the protective part 10, when the probe rods 420 are in the pressing state, the probe rods 420 can only be partially pressed on the top side of the protective part 10, and the ends of the probe rods 420 are easily placed on the workpiece 20 inside the protective part 10, so that the workpiece 20 is abraded or damaged.

Through the above arrangement, in the first direction, the dimension L2 of the probe rods 420 is greater than or equal to the dimension L1 of the protective part 10, so that when the probe rods 420 are in the pressing state, probe end portions are located on two sides of the protective part 10, thereby reducing the probability of the ends of the probe rods 420 crushing the workpiece 20.

According to some embodiments in the present application, please refer to FIG. 2, the auxiliary picking mechanism 400 further includes a position detecting part arranged on the base 100, the position detecting part is used for detecting the positions of the probe rods 420, and the position detecting part sends out a warning signal when the probe rods 420 descend to a limit position.

It can be understood that, when the probe rods 420 are in the pressing state, the lifting assembly drives the probe rods 420 to ascend and descend in the second direction. In addition to controlling the probe rods 420 to descend to the limit position through the lifting assembly, the position detecting part can also assist in controlling the positions of the probe rods 420. When the probe rods 420 descend to the limit position, the position detecting part can send out a warning signal, so as to prevent the probe rods 420 from crushing the workpiece.

Optionally, the position detecting part is a sensor, and the sensor may be a position sensor or a composite sensor, and the type of the sensor is not limited here.

Through the above arrangement, a situation that the workpiece will be crushed due to the descending of the probe rods 420 can be relieved.
