Description

Perovskite glass substrate loading carrier plate assembly and application method thereof

Technical Field

Background

Perovskite solar cells (Perovskite Solar Cells, PSCs) are a new generation of thin film solar cell technology with extremely high efficiency enhancement rates and great application potential. For rigid perovskite solar cells (as opposed to flexible cells), glass is the most popular, best performing substrate choice for rigid perovskite cells because glass is a dense mineral in nature, with extremely high hermeticity. In addition, the glass has extremely high light transmittance (generally > 90%) in the visible light range (the main absorption band of perovskite), and can ensure that most sunlight successfully passes through and is absorbed by an internal perovskite layer, so that electric energy is generated.

However, the fragility of glass substrates is the most obvious disadvantage, and there is a risk of breakage throughout the manufacturing chain and subsequent assembly installation, transportation and use, once broken, the entire device fails. This not only results in reduced yields, but also increases the cost and complexity of production.

Patent document 1 provides a robot positioning device in which a control robot grips a substrate from a conveyor belt through a central controller, and then places the substrate into a destination grid of a carrier plate. However, when this method is applied to the clamping of glass substrates, the glass substrates are easily damaged, and in addition, the upper surfaces of the glass substrates, which are close to the robot hand, are easily scratched, for example, by the robot hand or a contact during the operation of the robot hand, and even a tiny scratch may damage the integrity of the conductive layer, resulting in an increase in series resistance or uneven local conductivity, and eventually reducing the performance and lifetime of the battery.

Detailed Description

Based on the problems of the glass substrate introduced by the background technology, the embodiment mainly adopts a carrier plate as a component for bearing the glass substrate, so as to reduce the probability of possible breakage and scratch in the glass substrate transferring process. The core function of the carrier plate is to be used as a light-weight, high-precision and high-stability 'bearing component' for providing a flat and stable supporting plane and an accurate positioning reference for a single glass substrate. The glass substrate is convenient to position in the subsequent carrying process, and the positioning process is not in direct contact with the glass substrate, so that the glass substrate is the basis for improving the yield. As a "dedicated transport carrier" for the glass substrates, the carrier plate moves with the glass substrates between the various transport components of the apparatus, such as the work flows of loading, handling, tongue component transport, etc., in a manner that avoids direct grasping by the robot or frequent contact of the suction cups with fragile glass surfaces.

In addition, in the fabrication of extremely precision and environmental sensitive tips such as perovskite solar cells, carbon fibers are generally chosen as carrier materials rather than conventional metals, since carbon fiber density is extremely low, about 1/4 of steel, 1/2 of aluminum, but strength and modulus are higher. The light carrier plate allows the transfer equipment to run at higher speed and acceleration, shortens takt time, directly promotes output in unit time, is light in weight, is convenient for operation when manual or automatic intervene, and reduces the risk of industrial injury.

Referring to fig. 1, there is shown an apparatus for loading and unloading glass substrates 1, in which, for convenience of understanding, a plurality of glass substrates 1, a carrier 3 and a carrier 9 are shown at different positions on a frame 2, which does not represent that a plurality of glass substrates 1 are simultaneously present in the frame 2. The core of the operation flow of the device is that the glass substrate 1 is horizontally placed, loading, transporting and carrying of the carrier plate are realized through an automatic assembly, and finally the carrier plate 3 loaded with the glass substrate 1 is sent to a carrier 9 and is sent to subsequent process equipment (the process equipment is not shown in the drawing).

The invention is illustrated in the following examples:

Example 4 workflow of the Components

In this embodiment, the components for transferring glass substrates 1 as shown in embodiments 1,2 and 3, the core of the overall operation of the device assembly, which is constituted by, is to safely and precisely transfer fragile glass substrates 1 into a dedicated protective carrier plate 3, and to stack a plurality of "carrier plate-substrate" combination units into one carrier 9, and finally to transport them in their entirety to the next process equipment. The operation mode is shown in fig. 16, and is specifically as follows:

The glass substrate 1 is placed on the feeding conveyor belt 4.3 by manual or automatic equipment, the feeding conveyor belt 4.3 is started to convey the glass substrate 1 in the longitudinal direction, and when the glass substrate 1 moves to the position of the longitudinal limiting component 4.2, the edge of the glass substrate 1 is contacted with the limiting block, so that the movement is stopped. Subsequently, the first transverse limiting assembly 4.1 starts to work, and the guide rail seat 4.1.2 moves along the transverse guide rail 4.1.1 to drive the transverse clamping columns 4.1.6 filled with flexible materials to be close to the glass substrate 1 from two sides, so as to slightly clamp the glass substrate 1. To this end, the position of the glass substrate 1 in three dimensions is completely determined.

The substrate transfer assembly 5 moves above the loading station and the substrate longitudinal mover 5.1 and the substrate vertical mover 5.2 cooperate to position the clamp 5.3 directly above the glass substrate. The telescopic member 5.3.4 pushes the clamping bar 5.3.1 to move laterally, so that the lifting hook 5.3.2 moves below the edge of the glass substrate 1. The vertical movement 5.2 is slightly lowered a small distance to allow the lifting hook 5.3.2 to submerge into the bottom of the glass substrate 1. Subsequently, the vertical mover 5.2 is raised, and the lifting hook lifts the glass substrate 1 from below.

At the same time, the carrier plate moving assembly 6 sucks the uppermost one from the stacked blank carrier plates 3 with the carrier plate gripper 6.3 and places it on the bi-directional conveyor 7.1 of the assembly loading assembly 7. The bidirectional conveying member 7.1 runs forward, and conveys the carrier plate 3 to the position of the longitudinal limiting assembly 4.2 for stopping. The second transverse limiting component 7.2 is closed from two sides, and is used for transversely positioning the carrier plate, so that the positions of the substrate groove 3.2 and the lifting hook groove 3.3 on the carrier plate are accurate.

The transfer assembly 5 holding the glass substrate 1 moves to the position right above the positioned carrier plate 3, the vertical moving piece 5.2 of the transfer assembly 5 descends, the lifting hooks 5.3.2 move downwards through the lifting hook grooves 3.3 on the side face of the carrier plate, and finally the glass substrate is accurately placed in the substrate grooves 3.2 of the carrier plate. The telescopic piece 5.3.4 drives the lifting hook to move out transversely and separate from the glass substrate 1 and the lifting hook groove 3.3. The transfer assembly is lifted and returned to the standby position. The bi-directional conveyor 7.1 runs in reverse and carries the carrier plate 3 carrying the glass substrates 1 out of the assembly station.

The outgoing load carrier plate 3 is transported to the tongue component 8. The elastic conveyor belt 8.5 is driven by a motor to rotate, and the carrier plate is conveyed to the tongue plate 8.6.1. The carrier 9 is adjusted in height by the carrier vertical displacement member 9.3, so that the top surface of the currently empty layer of supporting blocks 9.2 is flush with the upper surface of the tongue plate 8.6.1. The longitudinal displacement member 8.6.2 pushes the tongue plate 8.6.1 to extend out, and the load carrier plate 3 on the tongue plate is stably conveyed into the carrier frame 9.1 and placed on two rows of corresponding supporting blocks 9.2. The carrier frame 9.1 is raised so that the load carrier plate 3 is disengaged from the tongue plate 8.6.1 and the tongue plate 8.6.1 is retracted to the home position ready to receive the next load carrier plate 3.

After the load carrier plate 3 is fully loaded with the carrier 9, the pushing plate 10.1 of the leveling assembly 10 can be pushed forward under the driving of the pushing plate longitudinal displacement member 10.2, so that all the carrier plates 3 are pushed to the inner side of the frame, the stacking is ensured to be neat, and the subsequent operation is convenient. The carrying assembly 11 clamps the whole carrier 9 and carries it to the feed port of the next process equipment for the subsequent perovskite cell manufacturing step.

The process greatly reduces the direct contact between the mechanical arm, the sucker and the like and the surface of the glass substrate, and obviously reduces the crushing and scratch risks through the modes of carrying by the carrier plate, lifting at the bottom and the like. Multiple components can work in parallel, the beat time is shortened, and the manual intervention is reduced in an automatic process. The multiple limiting assemblies and the precise movement modules ensure the positioning precision between the glass substrate and the carrier plate and between the carrier plate and the carrier, which is the basis of subsequent high-quality manufacturing. Finally, carrying is carried by taking the standardized carrier as a unit, and seamless butt joint is realized with a subsequent production line, so that modularization and automation of the manufacturing process are realized.
