At this time, the gas flow rate between the workpiece (including the wafer fixture 8 and the wafer material) placed on the Bernoulli suction cup and the Bernoulli suction cup is greater than the gas flow rate on the top of the workpiece.

[0069] Combination Figures 1 to 18 As shown, taking the loading and unloading of wafer electroplating as an example, the working principle and process of the present invention are as follows:
[0070] (For the convenience of description, the assembly state of the first P-axis flip drive assembly, the first flip support assembly, and the first loading and unloading suction cup assembly is recorded as unit A, and the assembly state of the second flip support assembly, the second flip support assembly, and the second loading and unloading suction cup assembly is recorded as unit B. The structures of unit A and unit B are exactly the same, so the components in unit A and unit B are still described with the same reference numerals.)
[0071] First, the process of loading material from the A unit to the front surface slot 71 of the electroplating rack 7 is described:
[0072] 1. The wafer picking arm 31 of the wafer robot 3 takes out a wafer 200 from the wafer box of the wafer box carrier 21 of the wafer box loading device 2 and moves it to the wafer calibration carrier 41 of the wafer aligner 4;
[0073] 2. The wafer aligner 4 performs positioning and edge finding on the wafer 200;
[0074] 3. The wafer picking arm 31 of the wafer robot 3 moves the wafer on the wafer calibration stage 41 to the first flip suction cup 581 of the flip robot 5;
[0075] 4. When the Z-axis linear module 52 of the flip robot 5 drives the wafer 200 on the first flip suction cup 581 to rise, the V-axis rotation module 56 drives the wafer 200 on the first suction cup 581 to rotate 180°, and the U-axis rotation module 54 drives the wafer 200 on the first suction cup 581 to rotate above the loading and unloading suction cup assembly 66 of the A unit of the installation and disassembly mechanism 6, the Z-axis linear module 52 drives the wafer 200 on the first suction cup 581 to descend, and the wafer 200 is placed on the material suction cup 665 of the loading and unloading suction cup assembly 66 of the A unit, and the outer ring of the wafer 200 is placed on the wafer fixture 8, and the flip robot 5 is reset;
[0076] 5. The fixture suction cup 664 of the loading and unloading suction cup assembly 66 sucks the wafer fixture 8, and the material suction cup 665 sucks the wafer;
[0077] 6. The screw motor 644 of the P-axis flip drive assembly 64 drives the floating plate 645 to rise, driving the flip drive connecting rod 652 to push up, so that the flip support assembly 65 and the loading and unloading suction cup assembly 66 thereon flip 90 degrees around the P-axis flip axis 6422 toward the electroplating hanger 7, as shown in FIG. Figure 8 As shown;
[0078] 7. The X-axis screw motor 632 of the X-axis sliding assembly 63 drives the P-axis flip driving assembly 64 to move along the X-axis linear guide rail 631 to a preset position close to the front of the electroplating rack 7;
[0079] 8. The airbag 662 of the loading and unloading suction cup assembly 66 inflates to push the wafer fixture 8 onto the electroplating hanger 7, and the fastening locks 82 of the wafer fixture 8 are inserted into the fastening lock slots 73 of the corresponding electroplating hanger 7 one by one;
[0080] 9. The linear motor 657 of the flip support assembly 65 drives the push block 658 to drive the push bearing 669 and the rotating support rod 668 of the loading and unloading suction cup assembly 66 to move, so that the loading and unloading suction cup assembly 66 rotates a certain distance around the W rotation axis 656, and the wafer fixture 8 is buckled on the electroplating hanger 7, and the wafer 200 is placed on the electroplating hanger 7;
[0081] 10. The loading and unloading suction cup assembly 66 stops working, the airbag 662 stops taking in air, and under the rebound effect of the spring connector 666, the fixture suction cup 664 is separated from the wafer fixture 8, the material suction cup 665 is separated from the wafer 200, and the flip support assembly 65 drives the loading and unloading suction cup assembly 66 to rotate around the W rotation axis 656 to reset;
[0082] 11. The rotating motor module 681 of the R-axis rotating assembly 68 drives the R-axis rotating base 682 to rotate 180° around the R-axis.
[0083] At this time, the positions of unit A and unit B are swapped, and the flip robot 5 transfers materials to unit B. After unit B receives the materials transferred by the flip robot 5, it feeds the materials to the back trough 71 of the electroplating rack 7. The specific process is the same as the process of unit A feeding the front trough 71 of the electroplating rack 7, and will not be repeated. After the back trough 71 of the electroplating rack 7 is loaded, the rotating motor module 681 of the R-axis rotating assembly 68 drives the R-axis rotating base 682 to rotate 180° around the R-axis to return the electroplating rack 7 to its original position. (Note: The two sides of the electroplating rack are not exactly the same, one side has RFID and the other side does not.)
[0084] When both surface grooves 71 of the electroplating rack 7 are loaded with materials, the overhead crane of the electroplating equipment clamps the electroplating rack 7 away; the unloading process is described below:
[0085] 1. The overhead crane of the electroplating equipment inserts the electroplating hanger 7 with the electroplated wafer into the Y-axis hanger socket 61;
[0086] 2. First, the A unit unloads the material from the front surface slot 71 of the electroplating hanger 7, the unloading and loading suction cup assembly 66 is started, the air bag 662 is inflated, the fixture suction cup 664 and the material suction cup 665 are moved at the same time, the fixture suction cup 664 sucks the wafer fixture 8, and the material suction cup 665 sucks the wafer 200;
[0087] 3. The linear motor 657 of the flip support assembly 65 drives the push block 658 to drive the push bearing 669 and the rotating support rod 668 of the loading and unloading suction cup assembly 66 to move, so that the loading and unloading suction cup assembly 66 rotates a certain distance around the W rotation axis 656, and the wafer fixture 8 is separated from the electroplating hanger 7;
[0088] 4. The airbag 662 of the loading and unloading suction cup assembly 66 stops taking in air. Under the rebound effect of the spring connector 666, the fixture suction cup 664 sucks the wafer fixture 8, and the material suction cup 665 sucks the wafer and separates it from the electroplating hanger 7. The flip support assembly 65 drives the loading and unloading suction cup assembly 66 to rotate around the rotation axis W to reset.
[0089] 5. The X-axis screw motor 632 of the R-axis rotating assembly 68 drives the P-axis flip driving assembly 64 to return to the initial position along the X-axis linear guide rail 631;
[0090] 6. The screw motor 644 of the P-axis flip drive assembly 64 drives the floating plate 645 to descend, driving the flip drive connecting rod 652 to pull back, so that the loading and unloading suction cup assembly 66 flips 90 degrees around the P-axis flip axis 6422 and returns to its original position;
[0091] To improve work efficiency, during the unloading period of unit A or unit B, steps 1 to 3 are repeated so that the transfer of the wafer 200 between every two adjacent workstations can be carried out continuously.
[0092] 7. The Z-axis linear module 52 of the flip robot 5 drives the rotating arm 57 to rise, and the U-axis rotating module 54 drives the rotating arm 57 to rotate to above the loading and unloading suction cup assembly 66 of the A unit, and the Z-axis linear module 52 drives the rotating arm 57 to descend, and the second flip suction cup 582 sucks the plated wafer on the loading and unloading suction cup assembly 66, and the Z-axis linear module 52 drives the rotating arm 57 to rise, and the U-axis rotating module 54 drives the rotating arm 57 to rotate back to its original position, and the V-axis rotating module 56 drives the rotating arm 57 to rotate 180°, and the wafer to be plated and the plated wafer are flipped and exchanged, and the U-axis rotating module 54 drives the rotating arm 57 to rotate back to above the loading and unloading suction cup assembly 66, and the Z-axis linear module 52 drives the rotating arm 57 to descend, and the wafer to be plated on the first flip suction cup 581 is placed on the material suction cup 665, and the outer ring of the wafer to be plated is placed on the upper wafer fixture 8;
[0093] 8. When the wafer fixture 8 and the wafer are placed on the electroplating hanger 7 by the A unit, the flipping manipulator 5 is reset, and the wafer picking arm 31 of the wafer robot 3 moves the electroplated wafer on the second flipping suction cup 582 of the flipping manipulator 5 into the wafer box of the wafer box loading device 2;
[0094] 9. The rotary motor module 681 of the R-axis rotating assembly 68 drives the R-axis rotary base 682 to rotate 180° around the R-axis, so that the positions of the A unit and the B unit are swapped, and the B unit unloads the material from the back station of the electroplating rack 7. The unloading process refers to the unloading process of the A unit. Since the unloading processes of the two are the same, they will not be repeated here;
[0095] 10. The wafer picking arm 31 of the wafer robot 3 moves the plated wafer from the second flip suction cup 582 of the flip robot 5 into the wafer box of the wafer box loading device 2;
[0096] At this point, one cycle of material replacement is completed, and the above steps are repeated until the wafers to be electroplated in the wafer box of the wafer box loading device 2 are processed.
[0097] In addition, the present invention may also include a transfer wafer box device 9. When the wafer robot 3 performs the wafer receiving action, the plated wafer can be transported to the wafer box of the wafer box loading device 2 or the wafer box of the transfer wafer box device 9 through the wafer picking arm 31, which can be selected according to actual needs; in particular, when the wafer vertical electroplating equipment matched with the present invention has the function of detecting plated wafers, when the wafer robot 3 performs the wafer receiving action, the wafer picking arm 31 can transport the plated wafers that have been detected OK to the wafer box of the wafer box loading device 2, and transport the plated wafers that have been detected NG to the wafer box of the transfer wafer box device 9.
[0098] After adopting the above scheme, the automatic loading and unloading equipment of the present invention has the following beneficial effects:
[0099] The loading and unloading equipment of the present invention replaces the original manual loading and unloading operation with automatic loading and unloading of the equipment, realizes automated operation, improves production efficiency, and replaces manual operation to improve the electroplating quality of wafer products; wherein the mounting and disassembly mechanism comprises a Y-axis hanger socket, an X-axis sliding assembly, a P-axis flip drive assembly, a flip support assembly, and a loading and unloading suction cup assembly; the electroplating hanger is inserted into the Y-axis hanger socket; a P-axis flip drive assembly is arranged on the side, and the P-axis flip drive assembly is connected to the Y-axis hanger socket through the X-axis sliding assembly, so that the P-axis flip drive assembly can be driven by the X-axis sliding assembly to move closer to or away from the electroplating hanger along the X direction; the loading and unloading The material suction cup assembly is connected to the P-axis flip drive assembly through the flip support assembly, so that when the P-axis flip drive assembly drives the flip support assembly to flip along the P-axis and move along the X-direction, it can drive the loading and unloading suction cup assembly to align with the material slot of the electroplating rack to complete the loading or unloading of wafer products, thereby realizing automatic loading and unloading, and the equipment operation and control are more flexible. When equipped with an electroplating rack with a double-sided slot, the P-axis flip drive assembly, flip support assembly and loading and unloading suction cup assembly of the installation and disassembly mechanism further include two each, which are respectively arranged on the double-sided slot side of the electroplating rack, and can also realize the loading and unloading of double-sided stations of the electroplating rack, with high efficiency. The flip robot can automatically realize the flipping and transportation of wafer products at two stations. After two suction cups are set, a single swing of the rotating arm can complete the material replacement operation of the wafer to be electroplated and the electroplated wafer at the same station, saving material replacement time and improving production efficiency. The loading and unloading suction cup assembly adopts the Bernoulli principle to suck the wafer fixture and wafer, and puts them onto the electroplating rack or separates them from the electroplating rack under the action of the airbag. The flip support assembly drives the Bernoulli suction cup assembly to rotate slightly around the rotating W axis, realizing the installation and removal of the wafer fixture and wafer from the electroplating rack, replacing the complex operation of manual loading and unloading of the original electroplating rack.
