[0032] Working principle of the invention:

[0033] The first handling robot 22 transports the magnetic coil column 211 from the magnetic coil column loading bin 21 and places it vertically on the magnetic coil column lifting and fixing plate 531. The wire guide motor 54 starts, and the active wire guide wheel 55 moves the tubing material forward until it is inserted into the wire foot of the magnetic coil column. Then the wire guide motor 54 stops, and the cutter 523 moves downward under the drive of the lower cutting cylinder 522, cutting the tubing material at the second wire guide hole 521. This completes the wire foot sleeve of the magnetic coil column. Then the first handling robot 22 transports the magnetic coil column to the lower magnetic core on the right side of the magnetic coil column feeding tray 31, which is fed by the external feeding tray structure at the beginning of the main conveyor track 3. The upper magnetic core is adapted to be provided on the left side of the magnetic coil column feeding tray 31. Driven by the main conveyor track 3, the magnetic coil column feeding tray 31 first reaches the magnetic coil column horizontal pushing and correction device, where the magnetic coil column is vertically positioned and calibrated. Then, the magnetic coil column feeding tray 31 is conveyed to the magnetic coil column pressing device, where the pressing block 673 descends and cushions the top of the magnetic coil column, thus fixing the magnetic coil column onto the lower magnetic core. The magnetic coil column feeding tray 31 is then conveyed to the air gap gasket assembly machine 23 for air gap gasket installation, followed by air gap gasket dispensing at the air gap gasket dispensing machine 24, and finally air gap gasket installation inspection at the dispensing inspection machine 25. Magnetic coil columns that fail the inspection are transferred to the dispensing failure unloading track 78 by the dispensing failure unloading mechanism, while magnetic coil columns that pass the inspection are conveyed to the upper magnetic core assembly mechanism for upper magnetic core assembly. During the assembly of the upper magnetic core, the pneumatic clamping claw 815 descends and picks up the upper magnetic core 831 placed on the magnetic ring column feeding tray 31. Then, driven by the flipping motor 814, the upper magnetic core 831 is rotated 180 degrees up and down. At this time, the mounting surface of the upper magnetic core 831 is facing down. Then, the second handling robot 26 removes the upper magnetic core 831 from the pneumatic clamping claw 815 and moves it to the top of the magnetic ring column for installation, thus completing the installation of the upper magnetic core and obtaining the transformer product.

[0034] Meanwhile, several jig seats 411 have been loaded onto the jig seat loading track 41 by the external jig seat loading mechanism. Each jig seat 411 is sequentially transported to the bottom of the cover body conveying mechanism by the jig seat loading track 41. At this time, the cover body 412 of the jig seat 411 is picked up by the pneumatic gripper 97 at the end of the cover body. The second handling robot 26 moves the magnetic ring column with the upper magnetic core installed into the jig seat 411. Then the second handling machine... The robotic arm 26 then moves the entire fixture seat 411 to the first end of the inspection unloading track 42. At the same time, the seat cover 412 is moved by the pneumatic gripper 97 at the end of the seat cover to the fixture seat 411 located on the inspection unloading track 42 and is lowered and adapted to be placed on the fixture seat 411. The fixture seat 411 with the seat cover 412 covered is sent to the bottom of the screw tightening sleeve 108 under the transmission of the inspection unloading track 42, and is also placed above the test lifting plate 113. The screw-tightening sleeve 108 is driven to descend and fit onto the connecting screw 413 on the top of the cover body 412. At the same time, the test lifting plate 113 is driven to rise until the pneumatic wire clamping claw 116 aligns with the wire of the magnetic coil column. Then, the pneumatic wire clamping claw 116 moves and clamps the wire of the magnetic coil column. The magnetic coil column positioning fixture 117 moves and presses against the magnetic coil column. The screw-tightening sleeve 108 is driven to rotate and begins to tighten the connecting screw 413, so that the cover body 412 begins to closely connect with the fixture seat 411. During the process, the cover body 412 exerts a downward pressure on the upper magnetic core and the entire transformer. At the same time, the electrical performance of the transformer is tested by the pneumatic wire clamping claw 116, and the data is calculated and displayed by an external test terminal. When the test value reaches the preset range, the transformer product is considered qualified. The screw tightening sleeve 108 stops rotating and rises to its reset position. The pneumatic lead clamping claw 116 and the magnetic coil column positioning fixture 117 both reset, and the transformer product is unloaded from the fixture seat 411 by the inspection unloading track 42. When the test value fails to reach the preset range as the screw tightening sleeve 108 continues to tighten, the product is judged to be unqualified. The screw tightening sleeve 108 stops rotating and rises to its reset position. The pneumatic lead clamping claw 116 and the magnetic coil column positioning fixture 117 both reset, and the transformer product is transferred from the fixture seat 411 to the unqualified product unloading track 121 for loading and unloading.

[0035] This invention is applicable to the production and assembly of TBEA photovoltaic transformers.
