[0041] The working principle of this utility model is:

[0042] When the utility model is in use, the AGV trolley is first used to transport the Cassette body 8 to the Cassette loading platform 3. The positioning Pin 4 in the Cassette loading platform 3 performs three-point positioning. The three first photoelectric sensors 5 work together to detect whether the Cassette body 8 is placed flat. After the detection is completed, the linear module 1 drives the Cassette loading platform 3 and the Cassette body 8 thereon to move downward. After the Cassette loading platform 3 descends to the specified position, the Cassette body 8 on the Cassette loading platform 3 cooperates with the limit block 11 in the Cassette workbench 10 to perform positioning. At the same time, the Cassette The four second photoelectric sensors 12 in the e workbench 10 work together to detect whether the Cassette body 8 is placed flat. After the detection is completed, the linear module 1 in the Cassette translation mechanism drives the Cassette workbench 10 to move linearly, and the Cassette body 8 is sent into the test loader. After being sent into the test loader, the first position sensor 13 will detect whether the Cassette workbench 10 has reached the working position in the test loader. The second position sensor 14 will detect whether the Cassette body 8 is placed on the Cassette workbench 10 when it reaches the working position in the test loader. At the same time, the linear module 1 in the loading platform elevator drives the Cassette workbench 10 to move linearly. The cassette loading platform 3 moves upwards and arrives at the material receiving waiting position, and the linear module 1 in the unloading platform elevator drives the Cassette unloading platform 6 to move downwards and arrive at the Cassette recycling waiting position. During the movement of the Cassette workbench 10, the Cassette handle plate 7 in the unloading platform elevator will level the handle 9 erected on the Cassette body 8 to prevent collision. Then the AGV trolley transports the Cassette body 8 to the Cassette loading platform 3, automatically locates and detects whether the Cassette body 8 is placed flat, and then the linear module 1 drives the Cassette workbench 10 to move the empty Cassette body 8 from the test loading platform The machine transports the Cassette to the recycling waiting position of the unloading platform elevator. The Cassette unloading platform 6 automatically positions and detects whether the Cassette body 8 is placed flat. After the detection is completed, the linear module 1 drives the Cassette unloading platform 6 and the empty Cassette body 8 on it to move upward and return to its original position. Then the linear module 1 drives the Cassette workbench 10 to continue moving and return to the material receiving area. Repeat the above steps to receive the next Cassette body 8, and then send the Cassette body 8 into the test loader. The AGV car takes away the empty Cassette body 8 on the unloading platform elevator, and then adds a new Cassette body 8 to the loading platform elevator.
