Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of semiconductor devices, and particularly relates to a fragile material conveying device, in particular to a perovskite glass substrate loading carrier and a use method thereof. BACKGROUND

[0002] Perovskite solar cells (PSCs) are a new generation of thin-film solar cell technology, with extremely high efficiency improvement speed and great application potential. For rigid perovskite solar cells (relative to flexible batteries), glass is the most mainstream and best-performing substrate choice for rigid perovskite solar cells, because glass is essentially a dense inorganic material, which has extremely high air tightness. Moreover, glass has extremely high light transmittance (usually > 90%) in the visible light range (the main absorption band of perovskite), which can ensure that most of the sunlight is successfully transmitted and absorbed by the internal perovskite layer, thereby generating electrical energy.

[0003] However, the fragility of the glass substrate is its most obvious disadvantage, which poses a risk of breakage throughout the manufacturing chain and subsequent assembly installation, transportation and use. Once broken, the entire device is disabled. This not only leads to a decrease in yield, but also increases the cost and complexity of production, so how to smoothly transport the glass substrate during loading is particularly important.

[0004] Patent document 1 discloses a sheet conveying device, which cooperates with several grabbing assemblies to enable the suction member to adsorb the sheet at the corresponding working position and transfer the sheet from one station to the next.

[0005] However, this adsorption method requires the top surface of the sheet to be removed, and when applied to the conveying process of the glass substrate, the upper surface of the glass substrate is easily scratched when in contact with the grabbing assembly. Even a small scratch can damage the integrity of the conductive layer, resulting in increased series resistance or uneven local conductivity, ultimately reducing the performance and life of the battery. In addition, by setting several grabbing assemblies to cooperate together, only a single sheet can be conveyed at a time, and multiple sheets cannot be conveyed together, resulting in low efficiency.

DETAILED DESCRIPTION

[0053] Based on the problems of the glass substrate introduced in the background art, the embodiment mainly uses a "carrier plate" as a component for receiving the glass substrate to reduce the probability of breakage and scratching during the transfer process of the glass substrate. The core function of the carrier plate is to serve as a lightweight, high-precision, and high-stability "supporting component" to provide a flat and stable support plane and an accurate positioning reference for a single glass substrate. This ensures that the glass substrate is easy to position during subsequent handling processes, and the positioning process does not directly contact the glass substrate, which is the basis for improving the "yield". As a "dedicated transportation carrier" for the glass substrate, the carrier plate moves with the glass substrate between various transmission components of the equipment, such as loading, handling, tongue component transmission, and other work processes. This approach avoids direct grabbing by a mechanical hand or frequent contact of a suction cup with the fragile glass surface.

[0054] In addition, in the precision and environment-sensitive tip manufacturing of perovskite solar cells, carbon fiber is generally chosen instead of traditional metal as the carrier plate material because carbon fiber has extremely low density, about 1 / 4 of steel and 1 / 2 of aluminum, but higher strength and modulus. Lightweight carrier plates allow the transfer equipment to operate at higher speeds and accelerations, reducing cycle time and directly improving output per unit time, and are lightweight, facilitating operation during manual or automated intervention and reducing the risk of injury.

[0055] Reference is made to the accompanying drawings Figure 1 which shows a device for loading and unloading glass substrates 1. For ease of understanding, the different positions of the multiple glass substrates 1, carrier plates 3, and carriers 9 on the frame 2 shown in the figure do not represent the simultaneous presence of multiple glass substrates 1 in the frame 2. The core of the device operation process is to place the glass substrates 1 horizontally, and to achieve loading, carrier plate loading, transmission, and handling through automated components, and finally to deliver the carrier plate 3 loaded with the glass substrates 1 to the carrier 9 and to the subsequent process equipment (not shown in the drawing).

[0056] The following embodiments will be specifically illustrated:

[0057] This specific embodiment is only an explanation of the present application, and is not a limitation of the present application. Those skilled in the art can make modifications to this embodiment without creative contribution after reading this specification, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.

[0058] Example 1: Perovskite glass substrate loading carrier plate assembly

[0059] Reference is made to the accompanying drawings Figure 2The loading carrier plate assembly 4 comprises a first lateral limiting assembly 4.1, a longitudinal limiting assembly 4.2, and a loading conveying belt 4.3; wherein the first lateral limiting assembly 4.1 is provided with at least two groups, which are respectively located at two sides of the loading conveying belt 4.3 along the lateral direction and are configured to be symmetrical along the longitudinal central axis of the loading conveying belt 4.3; the longitudinal limiting assembly 4.2 is provided with at least two groups, and the side surfaces of the plurality of groups of the longitudinal limiting assembly 4.2 close to the side of the glass substrate 1 are located on the same horizontal plane.

[0060] In the present embodiment, the glass substrate 1 moves along the longitudinal direction on the loading conveying belt 4.3, and the lateral direction is perpendicular to the longitudinal direction in the horizontal plane. When the glass substrate 1 moves to the longitudinal limiting assembly 4.2, it is stopped by the longitudinal limiting assembly 4.2, and then the first lateral limiting assembly 4.1 approaches the glass substrate 1 along the lateral direction. Since the glass substrate 1 is on the loading conveying belt 4.3, its horizontal height remains unchanged, so that the position of the glass substrate 1 in the three-dimensional space is actually uniquely determined under the limiting of the first lateral limiting assembly 4.1 and the longitudinal limiting assembly 4.2, so as to facilitate the subsequent transfer of the glass substrate 1 whose three-dimensional space position has been determined. In the present embodiment, the longitudinal limiting assembly 4.2 is configured as two rectangular columns with the topmost points higher than the glass substrate 1, and the two rectangular columns are located on the same vertical plane close to the side edge of the glass substrate 1. In the present embodiment, the loading conveying belt 4.3 is configured as two, and the top surfaces of the two loading conveying belts 4.3 are located on the same horizontal plane to support the glass substrate 1 to move forward in a horizontal state.

[0061] In the present embodiment, the first lateral limiting assembly 4.1 comprises a lateral guide rail 4.1.1, a guide rail base 4.1.2, a lifting base 4.1.3, a lateral clamping plate 4.1.5, and a lateral clamping column 4.1.6; wherein the guide rail base 4.1.2 is configured to move laterally along the lateral guide rail 4.1.1, the lifting base 4.1.3 is configured to be connected to the guide rail base 4.1.2, the lateral clamping plate 4.1.5 is configured to be connected to the lifting base 4.1.3, and the lateral clamping column 4.1.6 is configured to be connected to the lateral clamping plate 4.1.5 and at least partially intersect with the glass substrate 1 in the horizontal direction. The lateral guide rail 4.1.1 is one or a set of precisely machined linear guide rails, which are usually firmly installed on the equipment rack or base, with the running direction along the lateral direction. The lateral guide rail 4.1.1 is provided with high-precision ball or roller bearing tracks on the side edges, ensuring that the guide rail base 4.1.2 installed thereon can only move in a strict lateral straight line and cannot deviate or twist. The guide rail base 4.1.2 is a slider or moving base matched with the lateral guide rail 4.1.1, which has a matching receiving assembly inside to accurately clamp and slide along the lateral guide rail 4.1.1. The guide rail base usually has mounting holes for connecting other components, such as the lifting base 4.1.3. The lifting base 4.1.3 is a vertical structural member connected to the guide rail base 4.1.2, used to raise the lateral clamping plate 4.1.5 to the height of the glass substrate 1. The lateral clamping plate 4.1.5 is a plate-shaped structural member connected to the lifting base 4.1.3, which serves as the mounting base plate of the lateral clamping column 4.1.6. It needs to have sufficient rigidity and strength to ensure that it does not deform during clamping. The lateral clamping column 4.1.6 is the component that directly contacts the glass substrate 1, which is installed on the lateral clamping plate 4.1.5. The extension part of the lateral clamping column 4.1.6 overlaps with the edge area of the glass substrate 1 in horizontal projection, and the contact end part can be wrapped or made of flexible materials (such as polyurethane, POM, rubber, etc.) to avoid rigid impact and scratch the glass substrate 1.

[0062] Further, the lifting base 4.1.3 and the lateral clamping plate 4.1.5 are connected through an adjusting member 4.1.4, which is provided with a top end hole 4.1.4.1 and a side end slot 4.1.4.2. The lifting base 4.1.3 is provided with a connecting hole for connecting the side end slot 4.1.4.2, and the lateral clamping plate 4.1.5 is provided with a connecting slot 4.1.5.1 for connecting the top end hole 4.1.4.1. Referring to Figure 4, the adjusting member 4.1.4 is "L-shaped", having a top end horizontal plate and a vertical plate arranged on the top end horizontal plate, the top end hole 4.1.4.1 being arranged on the top end horizontal plate, and the side end slot 4.1.4.2 being arranged on the vertical plate. The top end hole 4.1.4.1 and the connecting slot 4.1.5.1, and the side end slot 4.1.4.2 and the connecting hole can be detachably connected by using a detachable connecting structure, such as a combination of a bolt and a nut, and the height position of the horizontal clamping column 4.1.6 and the distance close to the glass substrate 1 can be adjusted by adjusting the connecting point of the connecting structure on the side end slot 4.1.4.2 and the connecting slot 4.1.5.1, so as to adjust the actual position required according to the position and size of the glass substrate 1.

[0063] Referring to Figure 5 , a schematic view of the substrate transfer assembly 5 is shown. The substrate transfer assembly 5 includes a substrate longitudinal moving member 5.1, a substrate vertical moving member 5.2, and a clamping member 5.3. The substrate vertical moving member 5.2 is configured to move longitudinally along the substrate longitudinal moving member 5.1, and the clamping member 5.3 is configured to move vertically along the substrate vertical moving member 5.2, and the clamping member 5.3 is used to clamp the glass substrate 1.

[0064] In this embodiment, the substrate longitudinal moving member 5.1 is a precision mechanical platform providing linear motion in the longitudinal direction. Specifically, the substrate longitudinal moving member 5.1 is a rigid and precisely machined linear guide rail, which is strictly mounted on the equipment rack and extends in the longitudinal direction. Usually powered by a servo motor or a stepper motor, it cooperates with a ball screw or a synchronous belt to drive the sliding block / moving platform to perform high-precision and programmable linear motion. The sliding block / moving platform moves along the guide rail, and the substrate vertical moving member 5.2 is mounted thereon. The substrate vertical moving member 5.2 is configured to provide an actuator providing linear motion in the vertical direction, and the displacement mode thereof can refer to the substrate longitudinal moving member 5.1. In this embodiment, the specific moving mode of the substrate longitudinal moving member 5.1 and the substrate vertical moving member 5.2 is not further limited.

[0065] Referring to Figure 6 , the clamping member 5.3 includes a clamping rod 5.3.1, a lifting hook 5.3.2, a mounting beam 5.3.3, and a telescopic member 5.3.4. The lifting hook 5.3.2 is arranged at the end of the clamping rod 5.3.1, the telescopic member 5.3.4 is arranged at the end of the mounting beam 5.3.3, and the clamping rod 5.3.1 is arranged at the telescopic end of the telescopic member 5.3.4. The lifting hook 5.3.2 is used to abut against the bottom end edge of the glass substrate 1 and move the glass substrate 1 in the vertical direction.

[0066] In this embodiment, the telescopic member 5.3.4 is a driving unit providing lateral linear motion, which is fixed at the end of the mounting beam 5.3.3, and can be provided by a compact air cylinder or an electric cylinder to provide a short stroke, high precision linear reciprocating motion. The outer shell is fixed on the mounting beam 5.3.3, and the telescopic push rod is fixedly connected with the middle part of the clamping rod 5.3.1. The push rod is driven to extend or retract by air pressure or electric signal, and drives the clamping rod 5.3.1 and the lifting hook 5.3.2 to move "close" and "far" laterally. The lifting hook 5.3.2 is the only part in contact with the glass substrate 1, which is usually an L-shaped hook mounted on both sides of the clamping rod 5.3.1. The contact part of the lifting hook 5.3.2 with the glass substrate 1 is made of or wrapped with flexible scratch-resistant material (such as POM, Teflon, engineering rubber or wrapped soft silicone), so that it forms a "lift" rather than a "clamp" on the glass substrate 1, achieving the purpose of "not directly contacting the upper surface of the glass substrate during the positioning process", which protects the fragile and easily scratched glass substrate and improves the production yield.

[0067] Reference Figure 9 , shows the specific structure of the carrier plate moving assembly 6. The carrier plate moving assembly 6 includes a carrier plate lateral moving member 6.1, a carrier plate vertical moving member 6.2, and a carrier plate grabbing member 6.3; wherein the carrier plate vertical moving member 6.2 is configured to move laterally along the carrier plate lateral moving member 6.1, and the carrier plate grabbing member 6.3 is configured to move vertically along the carrier plate vertical moving member 6.2, and the carrier plate grabbing member 6.3 is used to grab the carrier plate 3. In this embodiment, the carrier plate grabbing member 6.3 uses a suction cup to suck the upper surface of the carrier plate 3, and then places the carrier plate 3 to the designated position by canceling the suction, so that the lifting hook 5.3.2 corresponds to the lifting hook slot 3.3.

[0068] Reference Figure 10, the specific structure of the assembling and feeding assembly 7 is shown. The assembling and feeding assembly 7 comprises a bidirectional conveying member 7.1 and a second lateral limiting assembly 7.2; wherein the second lateral limiting assembly 7.2 is provided with at least two groups, respectively located at two sides of the bidirectional conveying member 7.1 along the lateral direction and configured to be symmetrical along the longitudinal central axis of the bidirectional conveying member 7.1; and the sides of the plurality of longitudinal limiting assemblies 4.2 close to one side of the carrier plate 3 are in the same horizontal plane. In this embodiment, the structure of the bidirectional conveying member 7.1 is basically consistent with that of the feeding conveying belt 4.3, except that the bidirectional conveying member 7.1 can switch between forward and backward operation along the longitudinal direction. The second lateral limiting assembly 7.2 is consistent with the structure of the first lateral limiting assembly 4.1, and the second lateral limiting assembly 7.2 and the first lateral limiting assembly 4.1 are respectively provided at two sides of the longitudinal limiting assembly 4.2 along the longitudinal direction. In use, the carrier plate grabbing member 6.3 places the carrier plate 3 on the bidirectional conveying member 7.1, and the bidirectional conveying member 7.1 runs towards the direction of the longitudinal limiting assembly 4.2, so that the edge of the carrier plate 3 close to the longitudinal limiting assembly 4.2 is abutted against the longitudinal limiting assembly 4.2, and then the glass substrate 1 is placed above the carrier plate 3 by the clamping member 5.3. After placement, the bidirectional conveying member 7.1 runs away from the direction of the longitudinal limiting assembly 4.2, so that the carrier plate 3 is away from the longitudinal limiting assembly 4.2, and is conveyed to the next assembly, such as a perovskite glass substrate feeding carrier, so as to facilitate subsequent processing of the glass substrate 1.

[0069] Embodiment 2: Carrier plate for carrying perovskite glass substrate

[0070] In this embodiment, referring to Figure 7The carrier plate 3 comprises a plate body 3.1, a substrate groove 3.2 and a lifting hook groove 3.3. The substrate groove 3.2 is arranged on the top surface of the plate body 3.1 and used for accommodating the glass substrate 1. The lifting hook groove 3.3 is arranged on the side end of the plate body 3.1 and used for allowing the lifting hook 5.3.2 to pass through in the vertical direction. The plate body 3.1 is the main body and basic frame of the carrier plate 3. It is a plate-shaped object with considerable thickness, rigidity and flatness, usually made of lightweight, high-strength and less-deformable materials, such as carbon fiber composite materials, for carrying the weight of the glass substrate 1 and providing a protective frame for the glass substrate 1. The substrate groove 3.2 is a recessed area precisely machined on the top surface of the plate body 3.1. Its opening contour matches the shape of the glass substrate 1, but the size is slightly larger to facilitate the installation of the glass substrate 1 therein. The lifting hook groove 3.3 is a vertical slot opened on the side end of the plate body 3.1. Its position corresponds to the horizontal position of the lifting hook 5.3.2 on the clamping piece 5.3. The width of the lifting hook groove 3.3 is slightly larger than the thickness of the lifting hook 5.3.2, providing the necessary movement gap. When the clamping piece 5.3 moves to the top of the plate body 3.1 while holding the glass substrate 1, the position of the lifting hook 5.3.2 is aligned with the lifting hook groove 3.3. The substrate vertical moving piece 5.2 drives the glass substrate 1 to move downward into the substrate groove 3.2. The lifting hook 5.3.2 with the glass substrate 1 moves vertically downward through the "passage" of the lifting hook groove 3.3, and finally places the glass substrate 1 stably in the substrate groove 3.2.

[0071] Reference Figure 8 The carrier plate stacking assembly 12 can stack multiple carrier plates 3 together for unified access. The carrier plate stacking assembly 12 comprises a stacking frame 12.1, and the longitudinal width and the transverse width of the stacking frame 12.1 are greater than the longitudinal width and the transverse width of the carrier plate 3, respectively. Multiple carrier plates 3 are placed on the stacking frame 12.1 in a stacked manner

[0072] Further, the carrier plate stacking assembly 12 further comprises a mounting frame 12.2; wherein the mounting frame 12.2 is arranged on the frame 2 and used for mounting the stacking frame 12.1.

In this embodiment, the longitudinal displacement piece 8.6.2 is a magnetic coupling air cylinder with a model of RMT16X450SA to realize the function of driving the tongue plate 8.6.1 to displace in the longitudinal direction. The longitudinal displacement piece 8.6.2 can also be any assembly capable of driving the tongue plate 8.6.1 to displace in the longitudinal direction in the prior art, and the present embodiment is not limited further.

[0077] Further, referring to Figure 13Further, a carrier 9 for installing the plurality of load glass substrates 1 is provided, the carrier 9 comprising a frame 9.1, a plurality of blocks 9.2, and a carrier vertical displacement device 9.3; wherein the frame 9.1 is arranged on the carrier vertical displacement device 9.3 and is configured to move vertically along the carrier vertical displacement device 9.3, the blocks 9.2 are arranged on the inner side of the frame 9.1 and are respectively located on the two lateral sides of the inner side of the frame 9.1, the blocks 9.2 are arranged in pairs on the two lateral sides of the inner side of the frame 9.1, and the upper top surfaces of the two corresponding blocks 9.2 are on the same horizontal plane; the lateral distance between the two corresponding blocks 9.2 is greater than the lateral width of the tongue plate 8.6.1. In the embodiment, the specific steps for the tongue device 8.6 to transfer the carrier 3 of the load glass substrate 1 to the carrier 9 are as follows: adjusting the height of the frame 9.1 by the carrier vertical displacement device 9.3, so that the upper top surfaces of the two uppermost corresponding blocks 9.2 are on the same horizontal plane as the lower bottom surface of the carrier 3 of the load glass substrate 1; then driving the tongue plate 8.6.1 to extend into the frame 9.1, so that the carrier 3 of the load glass substrate 1 is inserted above the upper top surfaces of the two uppermost corresponding blocks 9.2; then adjusting the height of the frame 9.1 upward by the carrier vertical displacement device 9.3, so that the carrier 3 of the load glass substrate 1 is separated from the tongue plate 8.6.1; finally, driving the tongue plate 8.6.1 to withdraw from the frame 9.1, thereby completing the work flow of installing the carrier 3 of the load glass substrate 1 into the carrier. In addition, if it is necessary to continuously complete the work of installing the carriers 3 of a plurality of load glass substrates 1 into the carrier, when the carrier 3 of the load glass substrate 1 is separated from the tongue plate 8.6.1 by adjusting the height of the frame 9.1 upward by the carrier vertical displacement device 9.3, the upper top surfaces of the two corresponding blocks 9.2 on the lower side of the carrier 3 of the load glass substrate 1 are adjusted to be on the same horizontal plane as the lower bottom surface of the carrier 3 of the next load glass substrate 1 to be installed, so that the next installation can be completed by the tongue plate 8.6.1 extending into and withdrawing from the frame 9.1 again.

[0078] Further, with reference to Figure 14Further, a flattening assembly 10 for flattening the carrier plate 3 of the plurality of load glass substrates 1 already installed into the carrier 9 is also included, the flattening assembly 10 comprising a pushing plate 10.1, a pushing plate longitudinal displacement member 10.2, and a fixing frame 10.3; wherein the pushing plate 10.1 is arranged at the movable end of the pushing plate longitudinal displacement member 10.2 and is configured to move longitudinally, and the fixed end of the pushing plate longitudinal displacement member 10.2 is arranged on the fixing frame 10.3. In this embodiment, the method for flattening the carrier plate 3 of the plurality of load glass substrates 1 already installed into the carrier 9 by the pushing plate 10.1 is to push the pushing plate 10.1 inwardly into the frame 9.1 by the pushing plate longitudinal displacement member 10.2, so that the outer end faces of the carrier plate 3 of the plurality of load glass substrates 1 are located on the same vertical plane, facilitating the subsequent operation step of taking out the carrier plate 3. The vertical height of the pushing plate 10.1 is greater than the total height of the carrier plate 3 of the plurality of load glass substrates 1. The material of the pushing plate 10.1 is a flexible material to avoid damage to the carrier plate 3 of the load glass substrates 1.

Wherein, the pushing plate 10.1 is located within the transverse range formed by the auxiliary groove 9.4, which can be understood as being able to just fit into the auxiliary groove 9.4 when the pushing plate 10.1 is pushed inwardly into the frame 9.1, so that the pushing plate 10.1 is not blocked by the edge of the frame 9.1 during the pushing process.

[0080] Further, referring to Figure 15 , a carrying assembly 11 for clamping the carrier 9 and moving the carrier 9 along the longitudinal direction is also included. The function of the carrying assembly 11 is to transfer the carrier plate 3 of the plurality of load glass substrates 1 to the next work site by the carrier 9 to perform the work of preparing perovskite solar cells.

[0081] Embodiment 4: Working process of each component

[0082] In this embodiment, the core goal of the entire running process of the device assembly composed of the components for transferring the glass substrates 1 as shown in embodiments 1, 2, and 3 is to safely and accurately transfer the fragile glass substrates 1 into a dedicated protective carrier plate 3, and stack a plurality of "carrier- substrate" combined units into a carrier 9, and finally transport the whole to the next process equipment. The running mode is as shown in Figure 16 , and the specific steps are as follows:

[0083] The glass substrate 1 is placed on the loading conveyor 4.3 by manual or automated equipment. The loading conveyor 4.3 is activated to transport the glass substrate 1 in the longitudinal direction. When the glass substrate 1 moves to the position of the longitudinal positioning assembly 4.2, its edges will contact the positioning blocks to stop the movement. Then, the first lateral positioning assembly 4.1 starts to work. The guide rail seat 4.1.2 moves along the lateral guide rail 4.1.1, and the lateral clamping column 4.1.6 with flexible material moves from both sides to the glass substrate 1 to gently clamp the glass substrate 1. At this time, the position of the glass substrate 1 in three dimensions is completely determined.

[0084] The substrate transfer assembly 5 moves above the loading station. The substrate longitudinal moving part 5.1 and the substrate vertical moving part 5.2 work together to position the clamping part 5.3 directly above the glass substrate. The telescopic part 5.3.4 pushes the clamping rod 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 moving part 5.2 slightly descends a small distance, so that the lifting hook 5.3.2 sinks into the bottom of the glass substrate 1. Then, the vertical moving part 5.2 rises, and the lifting hook lifts the glass substrate 1 from below.

[0085] At the same time, the carrier plate moving assembly 6 takes the uppermost one from the stacked blank carrier plates 3 by the carrier plate grabbing part 6.3 and places it on the bidirectional conveying part 7.1 of the assembly loading assembly 7. The bidirectional conveying part 7.1 runs forward to convey the carrier plate 3 to the position of the longitudinal positioning assembly 4.2 and stop. The second lateral positioning assembly 7.2 approaches from both sides to position the carrier plate laterally, ensuring the accurate position of the substrate slot 3.2 and the lifting hook slot 3.3 on the carrier plate.

[0086] The transfer assembly 5 holding the glass substrate 1 moves above the positioned carrier plate 3. The vertical moving part 5.2 of the transfer assembly 5 descends, and the lifting hook 5.3.2 moves downward through the lifting hook slot 3.3 on the side of the carrier plate, finally accurately placing the glass substrate into the substrate slot 3.2 of the carrier plate. The telescopic part 5.3.4 drives the lifting hook to move laterally out of the glass substrate 1 and the lifting hook slot 3.3. The transfer assembly rises and returns to the standby position. The bidirectional conveying part 7.1 runs in reverse to send the carrier plate 3 loaded with the glass substrate 1 out of the assembly station.

[0087] The outgoing load carrier plate 3 is transported to the tongue assembly 8. Its elastic conveyor belt 8.5 rotates under the drive of the motor, transporting the load carrier plate 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 current empty layer of the support block 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, stably sends the load carrier plate 3 on it into the carrier frame 9.1, and places it on the two corresponding support blocks 9.2. The carrier frame 9.1 rises, so that the load carrier plate 3 is separated from the tongue plate 8.6.1, and the tongue plate 8.6.1 retreats to the original position, ready to receive the next load carrier plate 3.

[0088] After the load carrier plate 3 is filled in the carrier 9, the push plate 10.1 of the flattening assembly 10 will be driven by the push plate longitudinal displacement member 10.2 to advance forward, and all the load carrier plates 3 will be pushed to the inside of the frame to ensure that the stack is neat, facilitating subsequent operations. The handling assembly 11 clamps the entire carrier 9 and moves it to the inlet of the next process equipment for subsequent perovskite battery manufacturing steps.

[0089] The above process greatly reduces the direct contact of mechanical hands, suction cups and the like with the surface of the glass substrate, significantly reduces the risk of breakage and scratching through load carrier plate bearing, bottom lifting and the like. Multiple assemblies can work in parallel, shortening the tact time, and the automatic process reduces manual intervention. Multiple limiting assemblies and precise motion modules ensure the positioning accuracy between the glass substrate and the load carrier plate, and between the load carrier plate and the carrier, which is the basis for subsequent high-quality manufacturing. Finally, the standardized carrier is used as a unit for handling, which is seamlessly connected to the subsequent production line, realizing the modularization and automation of the manufacturing process.

It needs to be further explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like in the description should be understood broadly, for example, "connection" can be fixed connection, can also be detachable connection, or integral connection; can be directly connected, or indirectly connected through an intermediate medium, or the communication between two elements.
