Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following description will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and fig. 2, the utility model provides a pair of material loading suction cup module, generally, material loading suction cup module includes suction cup main body 1. The suction cup body 1 includes a non-contact type suction cup 11 and a plurality of vacuum suction cups 12. The non-contact type suction cup 11 is arranged in the middle of the suction cup main body 1, and the plurality of vacuum suction cups 12 are uniformly arranged around the non-contact type suction cup 11. The suction cup main body 1 is provided with an air pipe 13 respectively communicated with the non-contact type suction cup 11 and the vacuum suction cup 12. The air pipe 13 is communicated with an air compressor (not shown) or an air pump (not shown). As shown in fig. 2, the arrow indicates the flow direction of the air flow when the material loading suction cup module is in operation. The non-contact type suction cup 11 is a bernoulli suction cup. In one embodiment, the non-contact suction cup 11 comprises a hollow housing and an internal baffle fixed on the housing, wherein the hollow housing is cylindrical, and a hole is formed in the center of the hollow housing and connected with an air compressor. When the non-contact type sucker 11 works, airflow enters a cavity in the Bernoulli sucker from the air pipe 13, due to the blocking of the inner baffle, the air is rapidly diffused outwards from the center of the circular inner baffle along the radial direction of the inner baffle, thereby the air flow speed at the upper part of the internal baffle is higher than that at the lower part of the internal baffle, and the compressed air takes away the local air to form a closed space, so that the air pressure in the central area and the periphery is lower than the external air pressure, because the air is evenly sprayed out along the horizontal direction after forming a vortex in the sucker cavity before flowing out, the downward acting force of the air flowing out to the solar cell is reduced to the minimum value, the adsorption force formed by the pressure difference between the central area, the peripheral air pressure and the external air pressure is greater than the sum of the gravity of the solar cell and the downward acting force of the air flowing out to the solar cell, and the solar cell is sucked up in the air. The suction is not completely in contact with the non-contact suction cup 11, but rather a very small stratosphere is present between the solar cell and the non-contact suction cup 11, so that a non-contact suction cup is provided. After the solar cell (solar cell) is sucked up in the air, the vacuum suckers 12 around the non-contact sucker 11 contact the solar cell (solar cell), so that the solar cell is firmly sucked by the vacuum suckers 12. The contact adsorption of the vacuum chuck 12 avoids the defect of unstable adsorption caused by the existence of a small stratosphere when the non-contact chuck 11 adsorbs.

Specifically, the sucker main body 1 is mounted on the mechanical arm 2 through a fastener, and when the mechanical arm 2 moves to a position above a solar cell (solar cell), and the sucker main body 1 is at a certain height from the solar cell, the sucker main body can be sucked up through the solar cell below the non-contact sucker 11 in an empty space without reducing the height of the mechanical arm 2; and then the solar cell is adsorbed by the vacuum chuck 12 to ensure firm adsorption, and then the mechanical arm 2 is moved to realize the loading or unloading of the solar cell.

Specifically, the non-contact type suction cup 11 is a bernoulli suction cup, and the vacuum suction cup 12 is an organ type vacuum suction cup. The number of the vacuum chucks 12 is 2 to 10. Preferably, the organ type vacuum chuck is made of silica gel, so as to reduce the breakage rate caused by the adsorption of the solar cell by the vacuum chuck 12.

In another embodiment, as shown in fig. 3, a gap 14 is provided between the non-contact type suction cup 11 and the vacuum suction cup 12, and penetrates through the main body 1 of the suction cup. The gap 14 can be used for flowing out of the air flow of the non-contact type sucker 11, and can also be used for conveniently adjusting the height of the non-contact type sucker 11, so that the sucker surface (front surface) of the non-contact type sucker 11 is higher than the sucker surface of the vacuum sucker 12, that is, the distance between the sucker surface of the non-contact type sucker 11 and the solar cell is slightly larger than the distance between the sucker surface of the vacuum sucker 12 and the solar cell. By the design, the solar cell can be firstly contacted with the vacuum sucker 12 after being sucked up by the non-contact sucker 11 in an air-separating way, so that the non-contact sucker 11 is prevented from being contacted, and the breakage rate of the solar cell is reduced.

As shown in fig. 4, 6 and 7, which are schematic structural diagrams of a material loading suction cup module in actual production, the suction cup main body 1 has a circular structure. The non-contact type suction cup 11 is disposed in the middle of the suction cup main body 1. A plurality of quick-connection and quick-release interfaces of the air pipes are arranged above the sucker main body 1 and are used for conveniently connecting the air pipes.

As shown in fig. 5, the utility model also provides a solar wafer loading attachment. The solar cell piece feeding device comprises the feeding sucker module, a material box 3, a mechanical arm 2 and a driving mechanism 4. The feeding sucker module is fixedly connected to the mechanical arm 2. The driving mechanism 4 adopts a driving motor and is used for driving the mechanical arm 2 to move; the edges of the two ends of the material box 3 are provided with air knife devices 5. The driving mechanism 4 adopts a driving motor.

In practical use, an operator puts 200 stacked solar cells 6 into the feeding box 3 at a time, and the solar cells are conveyed by the conveyor belt, so that the feeding box 3 moves to a feeding station; one end of the mechanical arm 2 is positioned at a certain height above the material box 3, and the air knife device 5 is started to blow air (the wind power blown by the air blowing head is generally 1.8-2 kg/cm)³) After the solar cells 6 stacked together are separated into single pieces, the feeding sucker module is started, air is pressed into the non-contact sucker 11, the non-contact sucker 11 generates suction force, the solar cells 6 are sucked up in an air-isolated mode, and then the vacuum sucker 12 is pumped out, so that the vacuum sucker 12 can firmly suck the solar cells; stopping pressing air into the non-contact type suction cup 11; the driving motor works to rotate the mechanical arm 2, so that the solar cell piece 6 is moved to the next station, and the solar cell piece 6 is arranged on the mechanical armAnd in the material process, after the material is moved to the next station, the vacuum chuck 12 stops being pumped, and the solar cell 6 can be automatically separated from the adsorption of the feeding chuck module.

It should be understood that the utility model discloses a material loading sucking disc module can also be used to the unloading process of solar wafer, and its theory of operation and process are similar.

The utility model provides a pair of material loading sucking disc module and solar wafer loading attachment can realize absorbing solar wafer's the sky, need not to set up the actuating mechanism that actuating mechanism moved to contact solar wafer again on the manipulator, only need set up the rotatory driving motor of an actuating mechanism and can realize the process of taking to solar wafer, the structure is simplified, the cost is reduced, the time that the manipulator removed to contact solar wafer has been reduced, the efficiency of taking of solar wafer has been improved.
