[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. However, the present invention is not limited to these embodiments. Any similar structures and similar variations of the present invention should be included within the scope of protection of the present invention. The use of directions such as up, down, front, back, left, and right in the present invention is only for the convenience of description and is not intended to limit the technical solution of the present invention.

[0017] Example 1

[0018] like Figures 1-7As shown, an AGV trolley fully automatic sample feeding device of the present invention includes a base 1, on which two guide rails 2 and a driving device are arranged. The two guide rails 2 are arranged in parallel and extend from left to right. A worktable 3 is arranged on the guide rails 2. The power output end of the driving device is connected to the worktable 3. A sample rack 4 is arranged on the worktable 3. Four first cylinders 5 are fixedly arranged on the lower side of the worktable 3. The piston rods of the first cylinders 5 all pass upward through the worktable 3 and are connected to the sample rack 4. A positioning frame 6 is arranged on the right side of the base 1. An opening is provided on the front side of the positioning frame 6. An AGV trolley 7 is arranged inside the positioning frame 6. Four second cylinders 8 are arranged on the positioning frame 6. A placement frame 9 is arranged above the positioning frame 6. The piston rods of the second cylinders 8 are all connected to the placement frame 9. Four brackets 10 are arranged on the placement frame 9. The driving device, the first cylinders 5, the AGV trolley 7, and the second cylinders 8 are all connected to the input and output end of a controller.

[0019] Furthermore, the bottom of the sample holder 4 is provided with four first positioning holes 11, and the piston rod of the first cylinder 5 is positioned with the first positioning hole 11 by a first positioning pin 12.

[0020] Furthermore, a positioning plate 13 is provided above the positioning frame 6, and the placement rack 9 is placed on the positioning plate 13. The positioning plate 13 is provided with four second positioning holes 14, and the piston rod of the second cylinder 8 is positioned with the second positioning hole 14 through a second positioning pin 15.

[0021] Furthermore, each of the aforementioned supports 10 is provided with a third positioning pin 17, and the bottom of the sample holder 4 is provided with a third positioning hole 18 that cooperates with the third positioning pin 17.

[0022] Specifically, in this embodiment, the guide rail 2, drive device, sample rack 4, first cylinder 5, AGV trolley 7, second cylinder 8, controller, etc., all adopt well-known solutions in the prior art, which are already known to those skilled in the art, and will not be described in detail here.

[0023] The working principle of this embodiment:

[0024] This device is used for trolley-type fully automatic thin plate tensile testing. During the test, the specimen is placed on the testing machine trolley. The testing machine trolley only performs cross-sectional measurement of the specimens, that is, all specimens on the testing machine trolley are measured on the cross-sectional measurement mechanism 16 at one time. After the measurement is completed, the specimens are placed on the specimen rack 4 on the worktable 3. Then, the AGV trolley 7 reaches the positioning frame 6 through the automatic path setting; the piston rod of the second cylinder 8 extends upward, positioning and lifting the placement frame 9 through the second positioning pin 15. Then, the piston rod of the first cylinder 5 on the worktable 3 extends upward, positioning and lifting the specimen rack 4 through the first positioning pin 12. The drive device drives the worktable 3 to move to the right along the guide rail 2, moving the specimen rack 4 above the placement frame 9. Then, the first cylinder 5 retracts, and the height of the bracket 10 is higher than that of the worktable 3, so that the specimen rack 4 falls on the bracket 10 and disengages from the worktable 3; then, the drive device drives the worktable 3 back to its original position along the guide rail 2; the AGV trolley 7 delivers the specimen rack 4 to the tensile testing machine through the automatic path setting.

[0025] The present invention discloses an AGV trolley fully automatic sample delivery device, which separates the cross-sectional measurement function and the tensile function on the testing machine trolley and uses the AGV trolley 7 for fully automatic storage, retrieval and transportation. This not only saves the sample waiting time, but also reduces the errors that may be caused by manual operation. In particular, when multiple devices need to be tested, the cross-sectional measurement process is carried out in a centralized manner, while the other devices only perform tensile tests, which significantly improves the testing efficiency and greatly saves costs.
