The loading and unloading tool of the utility model will be further explained below by taking the example of the loading and unloading tool auxiliary slicer for cutting silicon rod workpieces in the wire cutting system of the utility model. The working process of the loading and unloading tool provided by the utility model is as follows:

The silicon rod is carried to the side of the slicing machine 8 by using the stacking truck 7, and the vertical and horizontal positions of the suspension arm 11 are adjusted by adjusting the lifting table and rotating the rocking handle, so that the positioning plate 113 on the suspension arm 11 is abutted against the corresponding structure of the slicing machine 8. In this process, the work piece table 3 is fixed to the carriage assembly 2, the carriage assembly 2 is positioned at the innermost (rearmost) side of the boom assembly 1, and at the same time, referring to fig. 2, the locking member 12 is inserted into the first positioning groove 22, ensuring that the carriage assembly 2 does not fall off on the boom assembly 1, which is the first state. Then, the locking piece 12 is pulled up and rotated by a certain angle, so that the locking piece 12 is placed on the fixing seat 13 through the guide block, and the pulled locking piece 12 is kept in a state of always being separated from the positioning groove. The carriage assembly 2 is then moved forward along the first rail 114 until the workpiece is brought to the clamping position and the support bar 25 is withdrawn outwardly to disengage the workpiece table 3 from the mounting rail on the carriage assembly 2. The carriage assembly 2 is moved backwards until it is reset to the innermost position of the boom assembly 1, and the locking member 12 is turned such that the locking member 12 falls into the first detent 22. And removing the piling car to finish the rod loading work of the silicon rods.

After slicing the silicon rod, the silicon wafer needs to be taken down from the slicing machine 8 by using a loading and unloading tool to carry out the next procedure. According to the operation of the silicon rod on the rod, the suspension arm 11 is fixed at the same position, and the locking piece 12 is pulled up to be separated from the positioning groove. The carriage assembly 2 is pushed forward along the first rail 114 into the interior of the cutting chamber until the second stop 26 contacts the workpiece table 3, and the support bar 25 is inserted into the carriage plate 23 to secure the workpiece table 3 to the carriage assembly 2. The locking piece 12 is rotated, so that the guide block on the locking piece 12 is aligned with the guide groove 131 on the fixing seat 13, the locking piece 12 naturally falls under the action of gravity, and the lower end of the locking piece 12 is positioned in the first track 114 of the suspension arm 11. The water pan assembly 4 is fixed in the first working position, the sliding box 42 is pulled out forwards, then the bracket assembly 2 is slowly pulled out of the slicing machine 8 backwards, the bracket assembly 2 is moved backwards continuously, the second guide surface 121 of the locking piece 12 moves relatively along the upper edge of the bracket plate 23, and the lower end of the locking piece 12 falls into the second positioning groove 21 first, and referring to fig. 3, the second state is shown. During the backward movement of the bracket assembly 2, the locking member 12 is guided by the first guide surface 211, is ejected out of the second positioning groove 21, and continuously falls into the first positioning groove 22 along the upper edge of the bracket plate 23, and at this time, the rear end of the bracket assembly 2 contacts with the first limiting member 15, so as to complete the bar feeding operation. It should be noted that dropping the locking member 12 before resetting the cradle assembly 2 reduces the probability of forgetting the insertion operation of the locking member 12.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been shown and described herein in detail, many other variations or modifications of the utility model consistent with the principles of the utility model may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the utility model. Accordingly, the scope of the present utility model should be understood and deemed to cover all such other variations or modifications.
