[0002] Photovoltaic panel coating is a key step in improving the performance of photovoltaic modules. It involves coating the surface of cells or modules with thin films such as anti-reflective coatings, passivation layers and conductive layers. Anti-reflective coatings such as silicon dioxide and titanium dioxide are designed to reduce light reflection, increase light absorption and improve conversion efficiency. Passivation layers such as hydrogenated amorphous silicon and silicon nitride are used to reduce surface defects, reduce carrier recombination rates and improve cell performance. Conductive layers such as transparent conductive oxides are used for current collection. These thin films are precisely deposited through physical vapor deposition, chemical vapor deposition and other technologies to ensure film thickness, uniformity and quality to achieve the best performance of photovoltaic modules.

[0014] 1. The external photovoltaic panel workpiece is conveyed from right to left to the surface of the U-shaped roller conveyor line through the workpiece conveyor belt. The third electric telescopic rod drives the support rod to rotate upward, so that the roller bottom plate moves obliquely upward out of the inner cavity of the second trough shell to form a docking state with the U-shaped roller conveyor line.

The driving motor drives the internal sprockets of the front and rear two sets of chain assemblies to rotate synchronously under the coordinated drive of the gear, belt assembly and rotating shaft. The front and rear two sets of chain assemblies drive their own outer mounting plates to move circumferentially, and the inner mounting plate of the mounting frame keeps moving upward. After the outer mounting plate rotates to the inside, the support plate falls along the limiting groove to the lower position of the inner side of the mounting plate under the action of its own gravity, and then the photovoltaic panel workpiece is stored from top to bottom on the support plate surface inside the mounting frame.

[0015] 2. The AGV robot drives the chassis through the first grating sensor and enters the inner side of the feeding mechanism slot shell under the cooperation of the lifting module. The driving motor drives the two sets of chain assemblies to drive the inner mounting plate upward under the cooperation of the gear, belt assembly and rotating shaft, so as to move the photovoltaic panel workpiece from bottom to top to the position below the first three-axis grasping module. The first three-axis grasping module grasps the photovoltaic panel workpiece above the chassis and moves it to the feeding end position of the coating machine to complete the loading operation. The coating machine performs single-sided coating operation on the internal photovoltaic panel workpiece and moves to the rear discharge port position. The first electric telescopic rod drives the receiving plate to flip upward, and the driving module drives the ground rail platform to drive the base frame to move forward, and the electric flip The seat drives the mounting base plate to drive the bracket to flip, and the second electric telescopic rod drives the pushing frame to push the photovoltaic panel workpiece from the rear side of the bracket to the front side of the receiving plate. The left and right side lateral clamping modules clamp and fix the photovoltaic panel workpiece laterally, and the first electric telescopic rod drives the receiving plate to flip downward to a horizontal state, thereby completing the flipping operation of the photovoltaic panel workpiece after coating. The AGV robot drives the base frame after loading through the second grating sensor to enter the inner side of the outer shell of the unloading mechanism trough with the cooperation of the lifting module, and the second three-axis grasping module moves to the top of the receiving plate, and the lateral clamping module releases the clamping and fixation of the photovoltaic panel workpiece. The second three-axis grasping module grasps the photovoltaic panel workpiece above the receiving plate and moves it to the inside of the transfer mechanism for storage.

[0016] In summary, the present invention can coat both the upper and lower surfaces of the photovoltaic panels according to actual needs, improve the performance of the photovoltaic modules, overcome the limitations of single-sided coating and single-sided feeding and unloading of photovoltaic panel workpieces, and adopt automated feeding and unloading as well as loading and unloading methods, so that the production line can be flexibly configured, and the photovoltaic panels can be flipped and adjusted in coordination during the feeding and unloading process, assisting in the double-sided coating mode and reducing production time.

[0031] Step 1: The pre-made program inside the main control terminal 5 controls the AGV robot 61 to start remotely, and the AGV robot 61 moves along the predetermined route to the inside of the guide frame 10. The AGV robot 61 controls the lifting module 62 to disconnect from the base frame 63 to place the base frame 63 at a designated position inside the guide frame 10. The AGV robot 61 moves to the outside to wait or tow the base frame 63 at other positions.

[0032] Step 2: The external conveying device places the photovoltaic panel workpiece to be coated on the surface of the workpiece conveyor belt 7, and the workpiece conveyor belt 7 conveys the photovoltaic panel workpiece from right to left to the surface of the U-shaped roller conveyor line 8;

[0033] Step 3: The third electric telescopic rod 620 extends to drive the support rod 618 at the corresponding position to rotate upward, and drives the push rod 619 to move upward under the limiting effect of the support rod 618 on the other side.

[0039] Step nine: The AGV robot 61 drives the bottom frame 63 after loading to pass through the second grating sensor 32 and enter the inner side of the unloading mechanism trough shell 31 with the cooperation of the lifting module 62. The second grating sensor 32 senses the AGV robot 61 below and sends a signal to the inside of the main control terminal 5. The second positioning modules 33 on the left and right sides move inward to clamp and fix the bottom frame 63 on the left and right sides.
