[0018] The implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0019] In this embodiment: Reference Figure 1-2 As shown, a preferred embodiment of the present invention is provided.

[0020] The hoisting loading and unloading device of this embodiment includes a processing platform 1 and a processing station 2, wherein the processing station 2 includes a plurality of annularly distributed processing grooves, the processing platform 1 is located around the processing station 2 and is equipped with a hoisting plate 3 through a bracket 21, and a hoisting assembly 4 is guided on the hoisting plate 3, and the hoisting assembly 4 can move on the hoisting plate 3, and the hoisting assembly 4 includes a suction cup 49 for fixing the workpiece, and the hoisting assembly 4 drives the workpiece to turn and tilt. The four sides of the lifting tray 3 are respectively provided with a loading lifting rail 31, a first unloading lifting rail 32 and a second unloading lifting rail 33. A switching component 35 is installed near the second unloading lifting rail 33 of the lifting tray 3. The switching component 35 is used to switch the guide route between the lifting tray 3 and the second unloading lifting rail 33. The lifting component 4 moves into the annular lifting tray 3 through the loading lifting rail 31, so that the workpiece fixed on the lifting tray 3 is processed by the processing station 2, and leaves from the first unloading lifting rail 32. In this process, when it is detected that the quality of the workpiece on the lifting tray 3 is unqualified, the second unloading lifting rail 33 will be opened by the switching component 35, and the lifting tray 3 will be closed, so that the lifting component 4 will leave the second unloading lifting rail 33 in advance, thereby improving the processing efficiency; A sinker assembly 34 penetrating the hoisting plate 3 is installed on the processing station 2 , and the sinker assembly 34 is used to position the hoisting assembly 4 and drive the workpiece on the hoisting assembly 4 to realize lifting operation above the processing station 2 .

[0021] Furthermore, in the attached Figure 5 In the figure, guide wheels 45 are installed at the bottom of both sides of the lifting seat 41, and a guide motor 451 is also installed on the lifting seat 41. The guide motor 451 drives the two guide wheels 45 to rotate through a belt. The two guide wheels 45 are driven to rotate by the guide motor 451, thereby driving the lifting component 4 to move on the lifting plate 3, the first unloading lifting rail 32 and the second unloading lifting rail 33.

[0022] See attached Figure 4 As shown, the sinking assembly 34 includes a support rod 341 installed in the middle of the processing station 2, and the top of the support rod 341 is connected to an electric telescopic machine 342, the telescopic end of the electric telescopic machine 342 penetrates and extends to the top outer side of the hoisting plate 3, and a pressure plate 343 is fixed to the telescopic end, and a plurality of positioning probes 344 corresponding to the processing station 2 are installed on the pressure plate 343, and the pressure plate 343 is located below the positioning probe 344 and is also provided with a ring-shaped pressure head 345. When the hoisting assembly 4 moves to the processing groove on the processing station 2 and is identified by the positioning probe 344, the telescopic end of the electric telescopic machine 342 contracts to drive the pressure plate 343 to sink, and then the pressure head 345 is used to sink the workpiece fixed on the hoisting assembly 4 into the processing groove for processing. After the workpiece is processed, the pressure plate 343 rises, takes the workpiece out again, and then continues to enter the next processing groove for continuous processing; In the attached Figure 3In the figure, the switching component 35 includes a rotating shaft 354 and an electromagnetic lock 351 arranged at the bottom of the lifting plate 3, the electromagnetic lock 351 has a lock core 352 telescopically arranged inside, the lock core 352 is arranged in an arc shape, the outside of the rotating shaft 354 is respectively sleeved with a push-pull plate 356 and a gate rod 355, the end of the lock core 352 is connected to the end of the push-pull plate 356, and a first return spring 353 is arranged between the electromagnetic lock 351 and the push-pull plate 356, and the gate rod 355 is placed between the lifting plate 3 and the second unloading lifting rail 33. When the workpiece fixed on the hoisting assembly 4 is detected to be unqualified during the processing, the electromagnetic lock 351 is powered on to generate magnetic attraction to pull the gate rod 355 at the end of the lock core 352, thereby driving the gate rod 355 outside the rotating shaft 354 to rotate, and the gate rod 355 originally placed horizontally in the second unloading hoisting rail 33 is turned into the hoisting plate 3, which closes the passage of the hoisting plate 3 and opens the passage of the second unloading hoisting rail 33, allowing the hoisting assembly 4 to leave in advance under the guidance of the second unloading hoisting rail 33. After the unqualified workpiece leaves, the electromagnetic lock 351 is powered off and reset under the action of the first reset spring 353, at which time the gate rod 355 will be rotated back to the second unloading hoisting rail 33, allowing the subsequent hoisting assembly 4 to continue to move and process on the hoisting plate 3 with qualified workpieces.

[0023] It is worth noting that, referring to Figure 4 As shown, the hoisting assembly 4 also includes a hoisting seat 41, the internal bearing of the hoisting seat 41 is connected to a rotating drum 42, a steering motor 422 is installed on one side of the hoisting seat 41, and the steering motor 422 drives the rotating drum 42 to rotate through a belt, and a telescopic rod 43 is arranged inside the rotating drum 42, and a slide groove 431 is opened on one side of the telescopic rod 43. A limit block 421 is arranged on the inner wall of the end of the rotating drum 42, and the limit block 421 slides in the slide groove 431. In the process of the steering motor 422 driving the rotating drum 42 to rotate, the limit block 421 thereof is limited by the slide groove 431 of the telescopic rod 43, and pushes the telescopic rod 43 to rotate, thereby adjusting the workpiece fixed by the suction cup 49 at the end of the telescopic rod 43.

[0024] In the attached Figure 5 In the embodiment, the telescopic rod 43 is located at one end of the top of the hanging seat 41 and is provided with a force head 432. The telescopic rod 43 is located between the force head 432 and the hanging seat 41 and is also provided with a second return spring 44. When the force head 432 is squeezed by the pressure plate 343, the telescopic rod 43 is also pushed downward and compresses the second return spring 44. At the same time, the slide groove 431 of the telescopic rod 43 can slide in the rotating drum 42 through the limit block 421, and the telescopic rod 43 can be raised and lowered in the rotating drum 42 without affecting the rotation of the telescopic rod 43 driven by the rotating drum 42.

[0025] For further information, see Attachment Figure 6As shown, a weighing sensor 46 is installed at the bottom of the telescopic rod 43, and the weighing sensor 46 is used to perform real-time weighing operation on the workpiece adsorbed by the suction cup 49. When the workpiece enters the processing groove of the processing station 2 for cutting, grinding and polishing, once there is a large difference between the quality of the workpiece and the corresponding quality of the standard part, the system determines that the workpiece is a defective product and can be sent away in advance through the second unloading hoisting rail 33; The force-bearing part of the weighing sensor 46 is provided with a connecting rod 48, and a universal connecting ball 481 is provided at the end of the connecting rod 48. The top of the suction cup 49 is provided with a bite groove for connecting the universal connecting ball 481, so that after the suction cup 49 absorbs the workpiece, the multi-directional offset operation of the workpiece can be achieved through the cooperation of the universal connecting ball 481 and the bite groove; In order to realize the above-mentioned multi-directional offset operation of the workpiece, refer to the attached Figure 4 and attached Figure 6 As shown, the outer bearing at the end of the connecting rod 48 is connected to the reversing shaft 47, and a reversing motor 471 is installed on one side of the end of the telescopic rod 43. The output shaft of the reversing motor 471 drives the reversing shaft 47 to rotate through a belt. A tilting telescopic machine 472 is installed on the inner wall of one side of the reversing shaft 47, and a pulling block 473 is installed on the telescopic end of the tilting telescopic machine 472. An annular groove is opened on the top of the suction cup 49, and a slider 475 is slidably installed inside the annular groove. The pulling block 473 and the slider 475 are connected to each other. A pulling rod 474 is connected to the rotating shaft 75. Under the drive of the reversing motor 471, the reversing shaft 47 can drive the tilting and telescopic machine 472 to rotate axially along the connecting rod 48, so that the slider 475 at the end of the pulling rod 474 slides in the annular groove of the suction cup 49. This makes it possible for the tilting and telescopic machine 472 to rotate with the reversing shaft 47, and the slider 475 can be at different positions above the suction cup 49. At this time, the pulling rod 474 is pulled by the telescopic part of the tilting and telescopic machine 472 to enable the workpiece to complete the offset operation at different angles and directions.

[0026] The lifting and unloading device includes two lifting rails for unloading, and the lifting assembly 4 also includes a steering motor 422, a telescopic rod 43, a force head 432 and a weighing sensor 46. The steering motor 422 adjusts the rotation and lifting of the telescopic rod 43 through a limit block 421. The weighing sensor 46 is used to weigh and judge the quality of the workpiece in real time. When an unqualified workpiece is detected, the electromagnetic lock 351 controls the activity of the gate rod 355 through the lock core 352, so that the lifting assembly 4 with the unqualified workpiece fixed thereon leaves in advance through the second lifting rail 33 for unloading; The lifting and loading and unloading device includes a processing platform 1 and a processing station 2. The processing station 2 includes a plurality of annularly distributed processing grooves. The processing platform 1 is located around the processing station 2 and is equipped with a lifting plate 3 through a bracket 21. A lifting component 4 is guided on the lifting plate 3. A suction cup 49 for adsorbing zirconium dioxide blocks is provided on the lifting component 4. The lifting component 4 can deliver the zirconium dioxide blocks into different processing grooves by driving the workpiece to lift, turn and tilt, and adjust the state of the zirconium dioxide blocks according to the processing procedures during processing, without the need for additional manipulators or clamping components.
