[0043] Please refer to Figures 1 to 8 As shown, Embodiment 1 of the present utility model is: an automated drive shaft heat treatment processing line, including a loading mechanism 1, a positioning mechanism 2, a transfer mechanism 3, a turning mechanism 4, a workpiece storage mechanism 5, a heat treatment mechanism 6, a marking mechanism 7, and a blanking mechanism 8.

The workpiece storage mechanism 5 includes a fourth frame 51 and a workpiece storage rack 52 arranged on the fourth frame 51. The heat treatment mechanism 6 includes a fifth frame 61 and a heat treatment component 62 arranged on the fifth frame 61.

Position sensing sensors 45 are provided on the third frame 41, the fourth frame 51, the fifth frame 61, the sixth frame 71, and the seventh frame 81. The position sensing sensors 45 are used to detect whether the robot actually grabs a workpiece and places it on the lathe equipment for processing to prevent waste of time due to machining without material, or to detect whether the workpiece is placed in the reverse direction to avoid affecting the accuracy of groove cutting detection and subsequent processing, or to detect whether the center has risen to the appropriate position to prevent interference with the robot's loading and cause equipment damage, or to detect whether the marking needle moves, and then judge whether the marking needle actually operates to avoid missing marking and affecting subsequent traceability.

[0045] The working principle of this embodiment is as follows: During operation, first, the operator only needs to continuously place the workpieces into the loading area. Then, the feeding structure in the loading area will send the workpieces to the blanking induction detection structure one by one. Furthermore, the transfer mechanism 3 clamps the workpiece and places it in the turning area for processing. After processing, the processed finished product is placed into the workpiece storage mechanism, and the above operations are repeated. Then, the transfer mechanism 3 clamps and installs the workpiece on the workpiece storage mechanism into the heat treatment area. After processing, the processed finished product is placed into the marking area. Then, after marking, the transfer mechanism 3 places the processed finished product into the unloading area. Finally, the operator uniformly places the workpieces in the unloading area into the material box. During the process, if various abnormalities are detected by induction, the equipment will alarm and remind, and then the production supervisor will handle it.

[0046] In summary, for the automated drive shaft heat treatment processing line of the present utility model, the structures of each area of the processing line are clear, which can achieve continuous loading and unloading, increase production efficiency. The operator only needs to operate in the loading and unloading areas, and the rest are replaced by robots. It can cooperate with the robots for automated production more efficiently. Since it meets continuous operation, improves production efficiency, reduces the defective rate, and increases the yield rate.
