In the present embodiment, the number of the fixing cylinders 231 is two.
[0045] Reference Figure 2 Since the workpiece is formed by die casting, there will be flash after forming. The flash is easy to break and fall off during the positioning and coding process. In order to collect the flash, it also includes a guide cover 4 and a collection box 5. The guide cover 4 is welded and fixed to the frame 1. The workpiece is located directly above the guide cover 4, and the upper end of the guide cover 4 is opened. The lower end of the guide cover 4 is provided with a blanking port 41, and the orifice size of the blanking port 41 is smaller than the size of the upper end opening of the guide cover 4.
[0046] Reference Figure 2 The material collecting box 5 is connected to the frame 1, the top of the material collecting box 5 is opened, and the material dropping port 41 is located directly above the material collecting box 5, so that all the flash falling from the material dropping port 41 can be stored in the material collecting box 5; in order to facilitate the removal and dumping of the flash in the material collecting box 5, two guide strips 6 are welded on the frame 1, the two guide strips 6 are arranged in parallel, and a sliding cavity for the material collecting box 5 to be inserted is reserved between the two guide strips 6, and the material collecting box 5 can be slidably connected with the guide strips 6.

[0049] The implementation principle of a coding device for die-cast workpieces in an embodiment of the present application is as follows: the workpiece is placed on a frame 1 by a manipulator, and then the workpiece is moved until the positioning unit 2 recognizes that the workpiece has reached the coding position. The positioning unit 2 transmits an electrical signal to the coding unit 3, and the coding unit 3 works to code the workpiece. During the positioning and coding process, the burrs that fall from the workpiece enter the guide cover 4, and then flow into the collection box 5 through the confluence effect of the guide cover 4 for unified collection. When the burrs in the collection box 5 accumulate to a certain volume, force is applied to the collection box 5 so that the collection box 5 slides in the sliding groove 61 along the long side direction of the guide strip 6. At this time, the round head locking column 64 is disengaged from the locking hole 51, and the collection box 5 is taken out for dumping the burrs.
[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
