[0019] The present invention will be further described below in conjunction with the drawings and embodiments.

[0020] Refer to Figures 1 - 5 , a shell making production line includes a slurry dipping bucket 10, a sanding machine 20, and a manipulator assembly 30 for grabbing a workpiece 60. A slurry return mechanism 50 is arranged on one side of the slurry dipping bucket 10. The slurry return mechanism 50 is used for hanging the workpiece 60 so that the slurry drips into the slurry dipping bucket 10.

[0021] The utility model realizes that after the workpiece is dipped in slurry, the workpiece can be hung on the slurry return mechanism for slurry return by setting up a slurry return mechanism. When the workpiece is undergoing slurry return, the manipulator assembly can grab the remaining workpieces for slurry dipping and sanding operations, effectively improving the shell making efficiency.

[0022] See Figure 4 , the slurry return mechanism 50 includes a vertical rod 510 arranged on one side of the slurry dipping bucket 10, and a hook 540 is installed on the vertical rod 510. After the workpiece 60 is dipped in slurry, the manipulator assembly 30 suspends the workpiece on the hook 540, so that the slurry dripping from the workpiece 60 can drip into the lower slurry dipping bucket 10 to realize slurry return.

[0023] See Figure 4 , a first rotating element 520 is installed on the vertical rod 510, a second rotating element 530 is installed on the power output shaft of the first rotating element 520, and the hook 540 is fixedly installed on the power output shaft of the second rotating element 530. In this embodiment, the first rotating element 520 can drive the hook 530 to rotate, so as to drive the workpiece 60 to swing above the slurry dipping bucket 10, facilitating the accurate dripping of the dripping slurry into the slurry dipping bucket 10. At the same time, the second rotating element 530 can drive the hook 540 and the workpiece 60 to rotate. During the rotation process, as the workpiece 60 rotates, the slurry can be on the surface of the workpiece 60, so that the slurry can be more evenly wrapped on the surface of the workpiece 60.

[0024] Furthermore, the rotation axis of the first rotating element 520 is perpendicular to the rotation axis of the second rotating element 530.

[0025] Furthermore, the first rotating element 520 and the second rotating element 530 adopt existing technologies, such as motors.

[0026] See Figure 5 , the manipulator assembly 30 includes a multi-axis manipulator 310, and a gripper assembly 320 for gripping the workpiece 60 is installed at the connection end 311 of the multi-axis manipulator 310.

[0027] See Figure 5 , the gripper assembly 320 includes a fixing frame 321 fixedly arranged at the connection end 311, a gripper base 322 is arranged on the fixing frame 321, hooks 323 are arranged at intervals left and right at one end of the gripper base 322 away from the fixing frame 321, and the workpiece 60 is hung on the hooks 323; the interior of the gripper base 322 is hollow and the upper and lower ends are open, and a pressing rod 324 that can move up and down relative to the gripper base 322 is movably arranged in the gripper base 322, and a cylinder 325 for driving the pressing rod 324 to move up and down relative to the gripper base 322 is arranged on the fixing frame 321.

[0028] The operating principle of the gripper assembly 320 is that after the hanging rod 620 is hooked into the hook 323, under the action of the air cylinder 325, the pressing rod 324 presses against the upper end surface of the hanging rod 610 to complete the clamping. When separating, first drive the pressing rod 324 to separate from the upper end surface of the hanging rod 610 by the air cylinder 325, and then drive the hook 323 to separate from the hanging rod 620 by the multi-axis manipulator 310.

[0029] See Figure 1 The shell making production line further includes a suspension conveyor line 70, and a transfer hook 710 for hanging the workpiece 60 is arranged on the suspension conveyor line 70. The suspension conveyor line 70 uses an existing commercially available product, and its function is to drive a plurality of transfer hooks 710 to move along the movement track. The function of the suspension conveyor line 70 is to drive the workpiece hanging on the transfer hook 710 to move, and the loading or unloading of the workpiece 60 can be realized.

[0030] In the present utility model, the sand spraying machine 20 adopts a shower sand spraying machine or a floating sand spraying machine.

[0031] See Figure 1 and Figure 2 In one embodiment of the present utility model, there are two slurry dipping barrels 10 and the slurry returning mechanism 50, which are respectively the slurry dipping barrel A, the slurry dipping barrel B, the slurry returning mechanism A and the slurry returning mechanism B, and their working principles are as follows:

[0032] Step 1: The manipulator assembly grabs the first workpiece, moves the workpiece to the slurry dipping barrel A for slurry dipping. After the slurry dipping is completed, hang the workpiece on the slurry returning mechanism A so that the excess slurry on the workpiece surface drips back into the lower slurry dipping barrel A to achieve slurry returning;

[0033] Step 2: The manipulator assembly grabs the second workpiece, moves the workpiece to the slurry dipping barrel B for slurry dipping. After the slurry dipping is completed, hang the workpiece on the slurry returning mechanism B so that the excess slurry on the workpiece surface drips back into the lower slurry dipping barrel B to achieve slurry returning;

[0034] Step 3: The manipulator assembly grabs the workpiece located on the slurry returning mechanism A, moves the workpiece into the sand spraying machine for sand spraying. After the sand spraying is completed, transfer the workpiece to the designated position;

[0035] Step 4: The manipulator assembly grabs the third workpiece, moves the workpiece to the slurry dipping barrel A for slurry dipping. After the slurry dipping is completed, hang the workpiece on the slurry returning mechanism A for slurry returning;

[0036] Step 5: The manipulator assembly grabs the second workpiece located on the slurry returning mechanism B, moves the second workpiece into the sand spraying machine for sand spraying. After the sand spraying is completed, transfer the workpiece to the designated position;

[0037] Step 6: The manipulator component grabs the fourth workpiece, moves the workpiece to the slurry dipping bucket B for slurry dipping, and after the slurry dipping is completed, hangs the workpiece on the slurry returning mechanism B for slurry returning.
