[0017] Please see Figures 1-6 As shown, the embodiments of this utility model include: An automatic unloading structure for a centerless grinder gantry robot to move the material tray is used for automatic unloading of workpiece 2 after processing by a centerless grinder 1. It includes an unloading conveyor belt 3, a pushing and rotating assembly, and an unloading robot assembly.

[0018] The feeding end of the unloading conveyor belt 3 corresponds to the centerless grinder 1, and the unloading end corresponds to the unloading robot assembly. After the centerless grinder 1 finishes processing the workpiece 2, it is sent to the unloading robot assembly for collection via the unloading conveyor belt 3.

[0019] The top two sides of the feeding conveyor belt 3 are provided with limiting guards 4 to limit the conveying of the workpiece 2.

[0020] The material pushing and rotating assembly is located at the unloading end of the unloading conveyor belt 3 and is used to adjust the intermediate state of the workpiece 2. It includes a material pushing cylinder 5, a material seat 6, a bearing seat 7, a material lifting cylinder 8, a rotating cylinder 9, and a rotating seat 10.

[0021] The pushing cylinders 5 are laterally distributed and vertically fixed to the side of the unloading conveyor belt 3. The driving end of the pushing cylinders 5 is located above the unloading conveyor belt 3 and is provided with a material seat 6 located on the discharge end side of the limiting stop 4. The bottom center of the material seat 6 is provided with a one-way feeding groove 11 on the side of the limiting stop 4. When the workpiece 2 is sent from the unloading conveyor belt 3 out of the limiting stop 4 to the feeding groove 11 of the material seat 6, the pushing cylinders 5 push out to push the workpiece 2 out of the unloading conveyor belt 3. A third sensor assembly 12 is provided on the top of the material seat 6 at the material groove to sense whether the workpiece 2 has been conveyed to the correct position.

[0022] The bearing seat 7 is positioned on the other side of the feeding conveyor belt 3 relative to the pushing cylinder 5. The top of the bearing seat 7 is provided with a guide groove 13 parallel to the feeding groove 11. After the workpiece 2 is ejected, it falls into the guide groove 13.

[0023] The top-loading cylinder 8 is located on one side of the bearing seat 7 and is horizontally fixed on the side of the unloading conveyor belt 3. The driving end of the top-loading cylinder 8 is flush with the guide groove 13. The workpiece 2 is pushed out along the guide groove 13 by the top-loading cylinder 8.

[0024] The rotary cylinder 9 is located on the other side of the bearing seat 7. The rotary cylinder 9 is horizontally distributed and vertically fixed on the side of the unloading conveyor belt 3. The drive end of the rotary cylinder 9 is provided with a horizontally distributed rotating seat 10. The rotating seat 10 is recessed and has a positioning hole 14 that is flush with the guide groove 13. The workpiece 2 is pushed out by the top cylinder 8 to the positioning hole 14, and after being rotated 90° by the rotary cylinder 9, it is in a vertical state.

[0025] The feeding conveyor belt 3 is also equipped with a blocking mechanism on the front side of the feeding rotation assembly.

[0026] The blocking mechanism is provided in two sets, including a first blocking mechanism 15 and a second blocking mechanism 16 with the same structure. A workpiece 2 body position is provided between the first blocking mechanism 15 and the second blocking mechanism 16 for alternating blocking so that only one workpiece 2 is conveyed backward.

[0027] The first blocking mechanism 15 or the second blocking mechanism 16 includes a blocking cylinder 17 and a blocking block 18.

[0028] The blocking cylinder 17 is longitudinally fixed to one side of the feeding conveyor belt 3. The blocking block 18 has an L-shaped structure. The lateral end of the blocking block 18 is fixed to the driving end of the top of the blocking cylinder 17, and the longitudinal end is located on the conveying side of the top of the feeding conveyor belt 3, corresponding to and limiting the workpiece 2. The blocking cylinder 17 drives the blocking block 18 to lift and lower. When the blocking cylinder 17 is pushed out, the workpiece 2 can move and be conveyed on the feeding conveyor belt 3. When the blocking cylinder 17 is retracted, the longitudinal end of the blocking block 18 descends to limit the workpiece 2, blocking the conveying of the workpiece 2 on the feeding conveyor belt 3.

[0029] The front sides of the first blocking mechanism 15 and the second blocking mechanism 16 are respectively provided with a first sensor assembly 19 and a second sensor assembly 20, which are used to sense whether the workpiece 2 has been conveyed into place.

[0030] The unloading robot assembly includes a work platform 21, a Y-axis moving module 22, a base 23, a moving material tray 24, a mounting frame 25, an X-axis moving module 26, an unloading cylinder 27, and a gripper cylinder 28.

[0031] The working platform 21 is located on one side of the unloading end of the unloading conveyor belt 3. The Y-axis moving module 22 is horizontally fixed on the working platform 21 and has a horizontally distributed base 23 at the top drive end. The top of the base 23 is provided with a horizontally distributed moving tray 24. The moving tray 24 adopts a dot matrix tray. The moving tray 24 is driven by the Y-axis moving module 22 to move and adjust along the Y-axis direction, so as to orderly install the workpiece 2 into the moving tray 24 and ensure installation stability.

[0032] The mounting frame 25 is fixed on the working platform 21 in the form of a square arch structure. The X-axis moving module 26 is horizontally fixed on the top of the mounting frame 25. The unloading cylinder 27 is longitudinally distributed and fixed on the drive end of the X-axis moving module 26. The drive end at the bottom of the unloading cylinder 27 is provided with a downwardly distributed gripper cylinder 28. The X-axis moving module 26 and the unloading cylinder 27 are used to adjust the movement in the X-axis and Z-axis directions. The gripper cylinder 28 clamps the workpiece 2 to the moving material tray 24 for collection.

[0033] Working principle: Centerless grinder 1 grinds workpiece 2. When workpiece 2 is finished grinding, it enters the unloading conveyor belt 3. Workpiece 2 is first conveyed to the designated position. The first sensor assembly 19 detects workpiece 2, and the first blocking mechanism 15 is raised. Workpiece 2 moves sequentially to the second blocking mechanism 16. The second sensor assembly 20 detects workpiece 2, the first blocking mechanism 15 is lowered, and the second blocking mechanism 16 is raised. Workpiece 2 moves to the material seat 6 and is pushed to the bearing seat 7 by the pushing cylinder 5. It is then pushed out to the rotating seat 10 by the top cylinder 8. The rotating cylinder 9 rotates 90° so that workpiece 2 is rotated from horizontal to vertical. The gripper cylinder 28, with the cooperation of the Y-axis moving module 22, the X-axis moving module 26, and the unloading cylinder 27, sends workpiece 2 into the moving material tray 24 for collection. At this point, workpiece 2 completes the collection step and repeats the above operation until the moving material tray 24 is full.

[0034] In summary, the automatic unloading structure for a centerless grinder gantry robot arm that moves the material tray is compact, easy to operate and maintain, and adopts automated operation, effectively ensuring the stability of material collection, eliminating the need for manual operation and reducing labor intensity.
