Description

Technical Field

[0001] This invention relates to the field of carrier technology, and in particular to a universal transport carrier for photovoltaic modules and its method of use. Background Technology

[0002] Compared to traditional battery structures, back-contact batteries have higher energy density and lower internal resistance, resulting in improved safety and lifespan, as well as reduced production costs. Back-contact batteries often require a protective backplate on their back side.

[0003] Currently, during the production of back-contact solar modules, the backsheet needs to be transferred through multiple workstations. Due to the low strength of the backsheet, it is prone to bending and unevenness during transfer, which reduces the flatness of the backsheet. To ensure the flatness of the backsheet, a backsheet leveling process is required. Since the backsheet is a stacked module, relative sliding will occur between the stacks during transfer, which will also cause misalignment between the back-contact cells and the backsheet, ultimately greatly reducing the quality of the back-contact solar module. Therefore, this invention proposes a universal transfer carrier for photovoltaic modules and its usage method to solve the problems existing in the prior art. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a universal transfer carrier for photovoltaic modules and its usage method, which prevents the backsheet from bending or warping during the transfer process at the workstation.

[0005] To achieve the objectives of this invention, the invention is implemented through the following technical solution: A universal transfer carrier for photovoltaic modules, comprising a carrier plate, a vacuum generating device, and a vacuum breaking mechanism. The carrier plate has an upper panel and a lower panel on its upper and lower surfaces, respectively. The upper panel, carrier plate, and lower panel are all made of aluminum alloy and are fixed with glue to form an inner cavity. The four corners of the upper panel, carrier plate, and lower panel are fixed with pins. The upper panel has an adsorption hole communicating with the inner cavity. The bottom of the lower panel has a carrier plate support frame, and the inner side of the carrier plate support frame has five compartments. The vacuum generating device is installed inside each of the five compartments, and the vacuum breaking mechanism is installed in each of the compartments at both ends. The bottom of the lower panel has end positioning plates at both ends of the short side, and the bottom of the lower panel has a storage tank section. The storage tank section includes a gas storage tank and a small gas storage tank, and multiple sets of gas storage tanks are provided. One end of the bottom of the lower panel has a bottom inflation block.

[0006] The bottom inflation block is connected to the storage tank, and the storage tank is connected to the inner cavity through a vacuum generator. The vacuum breaking mechanism is connected to the storage tank to control gas emission.

[0007] A further improvement is that the vacuum breaking mechanism includes a main valve on / off mechanism, an automatic latch, and a mechanical valve. The automatic latch is connected to the mechanical valve, and the mechanical valve is connected to a small gas storage tank. The main valve on / off mechanism is connected to the gas storage tank.

[0008] A further improvement is that the end positioning base plate is provided with a vacuum breaking control pin hole, a vacuum breaking air hole and a positioning pin hole inside. The vacuum breaking control pin hole is connected to the automatic pin, the vacuum breaking air hole is connected to the inner cavity through a conduit and a solenoid valve is provided on the conduit, and the positioning pin hole is used for positioning.

[0009] A further improvement is that an inflation detection mechanism is installed on the carrier plate support frame, and the inflation detection mechanism is connected to the storage tank section to provide feedback on the capacity of compressed gas entering the storage tank and the small storage tank.

[0010] A further improvement is that: a sensing plate is installed at one end and on one side inside the carrier plate support frame, and the sensing plate is compatible with the sensors on the production line.

[0011] A further improvement is that foot plates are provided on both sides of the bottom of the carrier plate support frame and at the bottom of the two sets of end positioning seats.

[0012] A further improvement is that the vacuum generating device is equipped with a manual valve switch.

[0013] A further improvement is that the inner cavity includes a first cavity, a second cavity, a third cavity, a fourth cavity, and a fifth cavity, and the first cavity, the second cavity, the third cavity, the fourth cavity, and the fifth cavity are respectively connected to five sets of vacuum generating devices.

[0014] A method for using a universal transport vehicle for photovoltaic modules includes the following steps:

[0015] S1: In the initial stage, the industrial gas source introduces sufficient compressed gas into the storage tank and small storage tank through the inflation port of the bottom inflation block. The inflation detection mechanism provides feedback on the volume of compressed gas entering the storage tank and small storage tank.

[0016] S2: The air tank provides air to the inner cavity, and once the small air tank is filled with compressed gas, the main air tank's main air supply input is directly opened through the main valve on / off mechanism;

[0017] S3: Compressed gas in the gas tank flows through the vacuum generator, controlling the inner cavity to have a certain degree of vacuum, so that the upper panel firmly adheres to the battery back plate, thereby preventing slippage between the back plates.

[0018] S4: When the carrier is transferred to the last station, the sensor on the production line receives the signal from the induction plate, the clamp pin is inserted into the vacuum control pin hole, the automatic pin pushes the mechanical valve switch, the small air tank compressed gas control is invalid, the air tank compressed gas is immediately disconnected, reducing gas emissions;

[0019] S5: The vacuum vent is filled with compressed gas into the inner cavity, which accelerates the removal of negative pressure from the inner cavity. The vacuum level of the inner cavity instantly returns to zero, and then the photovoltaic cell module is transferred to the next work station, while the carrier is transferred back to the initial position for repeated use.

[0020] A further improvement is that, in step S3, during the adsorption process, the flow of compressed gas generating negative pressure in the first, second, third, fourth, and fifth chambers is directly controlled by a manual valve switch.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. The upper panel, carrier plate, and lower panel of this invention are made of aluminum alloy. The four corners are fixed with pins to ensure processing accuracy and the flatness of the upper panel after installation, thereby supporting the battery back panel and preventing the back panel from bending or warping during the transfer process at the work station.

[0023] 2. The upper panel of this invention has uniformly distributed adsorption holes, which is different from the commonly used rubber suction cup. This increases the adsorption area, enhances the ability of the inner cavity to adsorb the back plate, reduces vacuum leakage, and ensures that the back plate is firmly attached to the upper panel during transportation, thus avoiding bending and deformation of the back plate and slippage between the layers.

[0024] 3. This invention has five chambers. The middle second, third, and fourth chambers form one group, and the first and fifth chambers at both ends form another group. The vacuum generator that circulates compressed gas is equipped with a manual valve switch, which can control the corresponding chamber to work independently according to the size of the photovoltaic module, reducing the waste of gas source and avoiding the need to replace carriers of different specifications due to size incompatibility. Moreover, all actuators use gas source as energy source and do not use power supply, thus preventing power supply from damaging the photovoltaic cells.

[0025] 4. The bottom of the carrier plate support frame and the bottom of the end positioning seat plate of the present invention are equipped with foot plates with high flatness to ensure stability during workstation transfer. Attached Figure Description

[0033] Example 1

[0034] according to Figure 1 , 2 As shown in Figures 3, 4, and 5, this embodiment proposes a universal transport carrier for photovoltaic modules, including a carrier plate 1, a vacuum generating device 2, and a vacuum breaking mechanism 3.

[0035] The bottom inflation block 10 is connected to the storage tank, and the storage tank is connected to the inner cavity through the vacuum generator 2. The vacuum breaking mechanism 3 is connected to the storage tank to control gas emission. The upper panel 4, carrier plate 1, and lower panel 5 are fixed together with special glue, placed on a flat marble, and pressed together with a single metal plate.

[0038] Induction plates 18 are installed at one end and on one side inside the carrier support frame 6, and the induction plates 18 are compatible with the sensors on the production line.

[0041] according to Figure 1 , 2As shown in Figures 3, 4, and 5, this embodiment proposes a universal transport carrier for photovoltaic modules, including a carrier plate 1, a vacuum generating device 2, and a vacuum breaking mechanism 3. The carrier plate 1 has an upper panel 4 and a lower panel 5 on its upper and lower surfaces, respectively. The upper panel 4, carrier plate 1, and lower panel 5 are all made of aluminum alloy and are fixed with glue to form an inner cavity. The four corners of the upper panel 4, carrier plate 1, and lower panel 5 are fixed with pins. The upper panel has an adsorption hole that connects to the inner cavity.

[0045] Example 3

[0046] according to Figure 1 , 2 As shown in Figures 3, 4, and 5, this embodiment proposes a method for using a universal transport vehicle for photovoltaic modules, including the following steps:

[0047] S1: In the initial stage, the industrial gas source introduces sufficient compressed gas into the gas storage tank 8 and the small gas storage tank 9 through the inflation port of the bottom inflation block 10. The inflation detection mechanism 17 provides feedback on the volume of compressed gas entering the gas storage tank 8 and the small gas storage tank 9.

[0048] S2: The gas storage tank 8 provides the gas source for the inner cavity, and once the small gas storage tank 9 is filled with compressed gas, the main valve on / off mechanism 11 directly opens the input of the main gas source of the gas storage tank 8.

[0049] S3: Compressed gas in the gas storage tank 8 flows through the vacuum generator 2, controlling the inner cavity to have a certain degree of vacuum, so that the upper panel 4 firmly adheres to the battery back plate, thereby preventing slippage between the back plates; during the adsorption process, the manual valve switch 20 directly controls the opening and closing of the compressed gas that generates negative pressure in the first chamber 21, the second chamber 22, the third chamber 23, the fourth chamber 24 and the fifth chamber 25.

[0050] S4: When the carrier is transferred to the last station, the sensor on the production line receives the signal from the sensing plate 18, the clamp pin is inserted into the vacuum breaking control pin hole, the automatic pin 12 pushes the mechanical valve 13 to open and close, the small gas tank 9 compresses the gas control and the gas tank 8 is immediately disconnected to reduce gas emissions.

[0051] S5: The vacuum hole 15 is filled with compressed gas into the inner cavity, which accelerates the removal of negative pressure in the inner cavity. The vacuum degree of the inner cavity instantly returns to zero, and then the photovoltaic cell module is transferred to the next station, while the carrier is transferred back to the initial position for repeated use.

[0052] The upper panel 4, carrier plate 1, and lower panel 5 of this invention are made of aluminum alloy. The four corners are fixed with pins to ensure processing accuracy and the flatness of the upper panel 4 after installation, thus supporting the battery backsheet and preventing bending or warping during transport. Furthermore, the upper panel 4 has evenly distributed suction holes, a departure from commonly used rubber suction cups, increasing the suction area and enhancing the inner cavity's ability to adsorb the backsheet, reducing vacuum leakage. During transport, the backsheet adheres firmly to the upper panel 4, preventing bending deformation and slippage between layers. Simultaneously, this invention has five chambers: the middle second chamber 22, third chamber 23, and fourth chamber 24 form one group, while the end chambers 21 and fifth chamber 25 form another group. The vacuum generator 2, which circulates compressed gas, is equipped with a manual valve switch 20, allowing for individual control of the corresponding chambers based on the photovoltaic module's size, reducing gas waste and avoiding the need to replace carriers of different sizes due to size incompatibility. All actuators are powered by gas, eliminating the need for electrical power and preventing damage to the photovoltaic cells from electrical power.
