Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic component processing, and in particular to photovoltaic panel cell string welding processing equipment and a welding method thereof. Background Art

[0002] Photovoltaic modules are composed of multiple photovoltaic cells and are used to convert solar energy into electrical energy. They are an important component of photovoltaic power generation systems and are widely used in solar power stations, rooftops of homes and commercial buildings, and various other places.

[0003] When photovoltaic modules are being processed, multiple photovoltaic cells need to be serially soldered. The traditional photovoltaic cell serial soldering process mostly uses a transmission mechanism to transport the photovoltaic cells, cooperates with the wire drawing equipment to pull the tin soldering rod, and places the tin soldering rod on the positive and negative poles of the upper and lower surfaces of two adjacent photovoltaic cells for connection. Then, the tin soldering rod is heated by the heating equipment to realize the serial soldering between the two photovoltaic cells in turn. However, in the process of pulling the tin soldering rod, the tin soldering rod is mostly pulled after cutting, and the end lacks guidance and is easily offset, thereby affecting the subsequent precise serial soldering of the positive and negative poles of the two adjacent photovoltaic cells. For this reason, we propose a photovoltaic panel cell serial soldering processing equipment and a welding method thereof to solve the above problems. Summary of the Invention

[0016] A welding method for photovoltaic panel cell string welding processing equipment comprises the following steps:

[0017] Step 1: Pass the end of the soldering rod in the coiled state through the corresponding plurality of straightening wheels and the corresponding two control wheels in sequence, and clamp it into the two positioning clips in the corresponding positioning piece for positioning;

[0018] Step 2: Control the second motor to drive one of the control shafts to rotate, and cooperate with the two vertical transmission gears to engage and connect, drive the other control shaft to rotate in the opposite direction, thereby driving the corresponding two control wheels to rotate in the opposite direction synchronously, and then drive the tin soldering rod to automatically transmit to one side of the traction mechanism, and straighten it through multiple straightening wheels;

[0019] At the same time, the first motor is controlled to start driving the corresponding transmission shaft to rotate, thereby driving the transmission chain to transmit, and then controlling multiple traction parts to transmit. When multiple traction parts are transmitting, the installation shaft slides in the path guide frame, automatically and stably pulling multiple tin soldering rods, and moving toward the photovoltaic panel cell above the first transmission mechanism. When transmitted to the upper surface of the photovoltaic panel cell, the next traction part will be transmitted to the first rack position, and the corresponding two positioning slides in the multiple positioning parts are placed on the outside of the corresponding tin soldering rod to continue transmitting the traction part. The bottom of the rotating gear in the traction part is engaged with the top of the first rack, and the first rack drives the rotating gear and the first shaft to rotate, thereby controlling the double-headed screws in the multiple positioning parts to rotate, and then controlling the positioning clamps in the multiple positioning parts to move toward each other, positioning the tin soldering rod, and improving the stability of subsequent traction;

[0020] At the same time, the top of the rotating gear in the previous traction member meshes with the top of the second rack, and the transmission continues. The second rack drives the rotating gear and the first shaft to rotate in the opposite direction, thereby controlling the double-headed screws in the multiple positioning members to rotate in the opposite direction, and then controlling the positioning clamps in the multiple positioning members to move backward. The tin soldering rod loses its position, and one end of the tin soldering rod is stably placed on the upper surface of the photovoltaic panel cell.

[0021] The lifting cylinder is controlled to drive the adsorption rack and multiple suction cups to descend, and multiple suction cups adsorb and position the photovoltaic panel cells to be welded in series. Subsequently, the lifting cylinder is controlled to drive the photovoltaic panel cells to move upward. Subsequently, the telescopic cylinder is controlled to drive the photovoltaic panel cells to move above the first transmission mechanism and above the tin welding rod. At the same time, the tin welding rod cutter is placed at the end of multiple tin welding rods and automatically cuts them. The tin welding rod is automatically cut off, one end of which is placed on the upper surface of the previous group of photovoltaic panel cells, and the other end is placed on the lower surface of the next group of photovoltaic panel cells. Subsequently, the photovoltaic panel cells to be welded in series are controlled to descend and press on the upper surface of the tin welding rod to automatically place the photovoltaic panel cells to be welded in series.

[0022] Step 4. Similarly, multiple photovoltaic panel cells to be string-welded are placed alternately between the tin soldering rods in sequence, and with the transmission of the transmission belt in the first transmission mechanism, multiple photovoltaic panel cells to be string-welded are transmitted to the heating equipment to heat the tin soldering rods, and then cooled by the cooling equipment to realize automatic string welding of the photovoltaic panel cells.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. By setting up a traction mechanism and using a guide bar mechanism to automatically straighten and transmit multiple tin soldering rods, and being able to automatically pull multiple tin soldering rods, the end position of the tin soldering rod and the position to be cut can always be positioned during traction to prevent the tin soldering rod from shifting in position during traction, which would affect the string welding quality of multiple photovoltaic panel cells.

[0025] 2. By setting up a loading mechanism, the photovoltaic panel cells to be stringed are controlled to move horizontally and lift up and down, thereby realizing the automatic placement of the photovoltaic panel cells to be stringed, facilitating the subsequent string welding of the photovoltaic panel cells.

The tin soldering rod loses its position, and one end of the tin soldering rod is stably placed on the upper surface of the photovoltaic panel cell.

[0058] Step 3: Control and start the third motor 24 in the second transmission mechanism 52 to drive one of the transmission rollers 22 to rotate, thereby driving the transmission belt 23 in the second transmission mechanism 52 to transmit, thereby automatically transmitting the photovoltaic panel cells placed on the transmission belt 23 in the second transmission mechanism 52, and transporting the photovoltaic panel cells to be stringed to the bottom of the adsorption rack 54 in turn, and control the lifting cylinder 511 to drive the adsorption rack 54 and multiple suction cups 55 to descend, and the multiple suction cups 55 adsorb and position the photovoltaic panel cells to be stringed, and then control the lifting and lowering The cylinder 511 drives the photovoltaic panel cells to move upward, and then the telescopic cylinder 53 is controlled to be opened to drive the photovoltaic panel cells to move above the first conveying mechanism 2 and above the tin soldering rod.
