[0035] In one embodiment of the utility model, two sensors are provided on both sides of the jig. In other embodiments, two sensors can be arranged on both sides of the workbench 2. The two sensors are used to distinguish between the first jig 21 and the second jig 22 so that the two grippers of the robot 5 can accurately grip the blank and place the workpiece.

[0036] In one embodiment of the present invention, referring to Figure 1 As shown, the feeding port 31 faces the second direction X, the second direction X and the first direction Y are vertically arranged, and the first direction Y and the second direction X are both directions on a horizontal plane.

[0037] In one embodiment of the present invention, referring to Figure 1 As shown, the first fixture 21 and the second fixture 22 are distributed along the second direction X, that is, the first fixture 21 is closer to the lathe 3, and the waste trough 71 is arranged close to the second fixture 22. The positions of the first fixture 21 and the second fixture 22 correspond to the positions of the two clamps, so as to reduce the stroke of the robot 5.

[0038] In one embodiment of the present invention, referring to Figure 1 As shown, in order to prevent the manipulator 5 from accidentally injuring the operator, it includes a safety fence 4 fixedly connected to the ground, the safety fence 4 is arranged around the workbench 2, the safety fence 4 is provided with an open side 46, the safety fence 4 consists of four side surfaces, one of which is arranged as the open side 46, that is, the open side 46 is not provided with a fence, the lathe 3 is arranged on the open side 46 and the feeding port 31 is arranged opposite to the open side 46.

[0041] In one embodiment of the present invention, referring to Figure 1 As shown, rollers 9 are provided at the bottom of the frame to push the workbench 2 and the frame through the loading port 45.

[0042] The working principle of the automatic loading and unloading device of the utility model is:

[0043] At the loading station 8, the operator puts multiple blanks into the first fixture 21 and presses the start button. The stepper motor drives the first fixture 21 and the second fixture 22 to the material picking station 6. The first clamp 51 of the manipulator 5 clamps the blank on the first fixture 21 and transfers it to the chuck of the lathe 3. The lathe 3 starts to process the blank. At the same time, the second clamp 52 clamps the processed workpiece. The manipulator 5 transfers the workpiece to the top of the waste trough 71. At this time, the first air outlet and the second air outlet begin to blow air to clean the workpiece, and blow the fine chips and cutting fluid on the surface of the workpiece into the waste trough 71. The workpiece is then placed on the discharge position of the second fixture 22. This cycle is repeated until the second fixture 22 is full of workpieces. The stepper motor 1 drives the first fixture 21 and the second fixture 22 to move to the loading station 8. The operator unloads the workpiece on the second fixture 22 and loads multiple blanks onto the first fixture 21. This cycle is repeated.

[0044] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
