Description

Technical Field

[0001] This application relates to the field of conveying and positioning technology, and in particular to a thin-film solar cell leveling and positioning mechanism. Background Technology

[0002] In the laser marking, scribing, and edge cleaning processes of thin-film solar cells such as perovskite, telluride, and copper indium gallium selenide (CIGS) cells, the conveying of large-size glass products is involved to achieve precise positioning and processing. These large glass products can reach dimensions of 1600mm*2000mm or 1200mm*2400mm. During manufacturing, dimensional deviations occur in both length and width, resulting in natural warping of the product surface relative to the horizontal direction. The product surface is not an ideal plane. In automated processing, especially during laser marking, scribing, and edge cleaning, the Z-axis flatness of the product needs to be within ±0.05mm. Existing positioning mechanisms only position the product around its perimeter in the X-axis and / or Y-axis directions, which cannot meet the high-precision flatness requirements of large-size glass products. Utility Model Content

[0003] The purpose of this invention is to solve the aforementioned technical problems by providing a thin-film solar cell leveling and positioning mechanism, thereby meeting the high-precision flatness requirements of large-size glass products. To achieve the above objective, the technical solution of this invention is as follows:

[0004] A thin-film solar cell leveling and positioning mechanism includes a fixed frame, a movable frame, and a leveling component. The leveling component is disposed on the fixed frame and includes a support module and a liftable adsorption module. The support module is disposed along the Z-axis direction, and the adsorption module adsorbs the product so that it abuts against the support module. The fixed frame is provided with a liftable movable frame, which can be lowered to below the support module.

[0005] Specifically, the adsorption module is vertically and flexibly mounted on the support module.

[0006] Specifically, the support module includes a support plate and support members disposed on the support plate and near its two ends; the support members are provided to protrude relative to the surface of the support plate, and the support members are rolled within the support plate.

[0007] Specifically, the support module includes a support base and a support shaft disposed on the support base; the support plate is disposed on the support shaft, and the support base is mounted on the fixing frame.

[0008] Specifically, the adsorption module includes a lifting plate and suction cups disposed on the lifting plate and near its two ends; the suction cups penetrate the support plate, and the lifting plate is disposed on the support base.

[0009] Specifically, the suction cup is located between the support members arranged at both ends of the support plate, and the suction cup and the support members are located in the same straight line direction.

[0010] Specifically, it also includes a straightening component, which includes several groups of first positioning elements arranged along the Y-axis direction, with a first adjustment distance for positioning the product formed between two groups of first positioning elements.

[0011] Specifically, the alignment component includes several groups of second positioning elements arranged along the X-axis, and a second adjustment distance for positioning the product is formed between two groups of second positioning elements.

[0012] Specifically, the first adjustment distance and / or the second adjustment distance can adjustably adjust the product.

[0013] Specifically, the mobile frame includes a frame body and a plurality of transmission modules disposed on the frame body; the transmission module includes a transmission shaft and a plurality of rubber wheels mounted on the transmission shaft and spaced apart along its axial direction.

[0014] Compared with the prior art, the advantages of this utility model's thin-film solar cell leveling and positioning mechanism are mainly reflected in:

[0015] By setting up a liftable mobile frame, the product can be lowered below the support module to transfer it onto the support module. The product's own weight positions it on the support module, maximizing its fit and balance. This accommodates the deformation that occurs during the transfer from the mobile frame to the support module. Then, the adsorption module holds the product in the direction of gravity, ensuring that any naturally warped areas of the product are firmly against the support module, achieving a thorough leveling effect.

[0028] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0029] Example 1

[0030] This embodiment provides a thin-film solar cell leveling and positioning mechanism for positioning and transporting large-size glass products. It effectively levels the product surface to meet high-precision flatness requirements. The following is a detailed description, in which… Figure 1 The center line indicates that the X-axis represents the lateral direction, the Y-axis represents the longitudinal direction, and the Z-axis represents the vertical direction.

[0031] like Figures 1-4 As shown, a thin-film solar cell leveling and positioning mechanism includes a fixed frame 1, a movable frame 2, a leveling component, and a straightening component.

[0032] The fixed frame 1 is equipped with several leveling components and straightening components. The leveling components include a support module 3 and a liftable adsorption module 4. The support module 3 is arranged along the Z-axis so that the product can be positioned on the support module 3 by its own weight. The adsorption module 4 is used to adsorb the product so that the product is against the support module 3 in the direction of its gravity. The fixed frame 1 is equipped with a liftable movable frame 2, which can be lowered to below the support module 3.

[0033] The alignment component includes a first positioning module and a second positioning module. The first positioning module is located near both ends of the fixed frame, and the second positioning module is located near both sides of the fixed frame.

[0034] The first positioning module includes several sets of first positioning elements 5 arranged along the Y-axis. Two relatively spaced first positioning elements 5 are arranged on the same straight line along the Y-axis, forming a group. Multiple sets of first positioning elements 5 can be installed on the fixing frame 1. A first adjustment distance for positioning the product is formed between the two first positioning elements 5 in a group. The multiple sets of first positioning elements 5 can achieve stable positioning of the two ends of the product. In each group, one of the two first positioning elements 5 can be fixed to the fixing frame 1, while the other can be movable relative to the fixed first positioning element 5. It is understood that one of the first positioning elements 5 can be mounted on the fixing frame 1 using a driving component such as a cylinder, and this first positioning element 5 is elastic, meaning it can be mounted on the cylinder using an elastic component such as a spring. The two first positioning elements 5 clamping the product relative to each other can provide a certain degree of buffering and adjustment. When the product is positioned at the first adjustment distance, one first positioning element 5 abuts against one end of the product, while the other first positioning element 5 elastically abuts against the other end of the product, thereby effectively and adaptively positioning both ends of the product.

[0035] The second positioning module includes several sets of second positioning elements 6 arranged along the X-axis. Two relatively spaced second positioning elements 6 are arranged along the same straight line of the X-axis, forming a group. Multiple sets of second positioning elements 6 can be installed on the fixing frame 1. A second adjustment distance for positioning the product is formed between two grouped second positioning elements 6. The multiple sets of second positioning elements 6 can achieve stable positioning of the two side edges of the product. It is understood that the second positioning module has the same structure as the first positioning module, and the first and second adjustment distances at least partially overlap. This is used to regulate the perimeter of the product's plane. For example, if the product is a rectangular sheet structure, the long and wide sides of the product are regulated by the first and second positioning modules. In this embodiment, the first positioning element 5 and the second positioning element 6 are rollers.

[0036] The process of transporting products in a thin-film solar cell leveling and positioning mechanism is as follows: The product is placed on the movable frame 2, and the movable frame 2 gradually descends and approaches the fixed frame 1 until the movable frame 2 descends below the leveling component. The product is positioned on the support module 3 of the leveling component by its own weight. The leveling component straightens the four edges of the product. The adsorption module 4 of the leveling module rises and adsorbs the product, so that it completely abuts against the support module 3 along the Z-axis direction, thereby realizing the leveling operation of the product.

[0037] In this embodiment, a liftable movable frame 2 is provided, which can be lowered below the support module 3 to transfer the product onto the support module 3. The product's own weight is used to position it on the support module 3, so that the product achieves a maximum fit and balance on the support module 3 to accommodate the deformation that occurs when transferring from the movable frame 2 to the support module 3. Then, the adsorption module 4 is used to adsorb the product in the direction of gravity, so that the part of the product that is naturally warped is close to the support module 3, achieving a full leveling effect.

[0038] Example 2

[0039] This embodiment optimizes a thin-film solar cell leveling and positioning mechanism based on the above embodiments, and in particular provides a specific implementation of a leveling component:

[0040] like Figure 4 , Figure 5 As shown, the leveling assembly includes a support module 3 and a liftable adsorption module 4. The support module 3 is equipped with the adsorption module 4. The support module 3 includes a support base 33, a support shaft 34 disposed on the support base 33, a support plate 31 disposed on the support shaft 34, and a support member 32 disposed on the support plate 31.

[0041] The support base 33 includes a first fixing block 331 and a second fixing block 332. The bottom of the first fixing block 331 is provided with the second fixing blocks 332 arranged at intervals. The second fixing blocks 332 are detachably mounted on the fixing frame 1. The top of the first fixing block 331 is provided with support shafts 34 arranged at intervals. The support shafts 34 are located near the two ends of the first fixing block 331. The structure composed of the support base 33 and the support shafts 34 can achieve stable installation of the adsorption module 4.

[0042] The support plate 31 is provided with spaced-apart support members 32. There can be multiple support members 32. Each support member 32 protrudes from the surface of the support plate 31 and rolls within the support plate 31, enabling it to roll into contact with the bottom surface of the product. The support members 32 can be omnidirectional balls. In this embodiment, support members 32 are respectively provided near both ends of the support plate 31, ensuring balanced force distribution on the support members 32 and guaranteeing the stability of point contact between the support members 32 and the bottom surface of the product.

[0043] A liftable adsorption module 4 is provided on the support base 33, specifically on the first fixed block 331. The adsorption module 4 includes a lifting plate 41 and a suction cup 42 disposed on the lifting plate 41. The suction cup 42 penetrates the support plate 31. The lifting plate 41 is disposed on the support base 33. Under normal conditions, the height of the suction cup 42 extending out of the support plate 31 does not exceed the height of the support member 32. When the suction cup 42 is needed for adsorption, the height of the suction cup 42 can extend beyond the height of the support member 32. After adsorbing the product, the suction cup 42 can descend to the height equal to that of the support member 32, so that the product rests against the top of the support member 32. The lifting plate 41 is connected to a first driving member 43 that drives its lifting and lowering. The first driving member 43 can be an electric driving member, a hydraulic driving member, or a pneumatic driving member. In this embodiment, the first driving member 43 is a pneumatic driving member, specifically a cylinder. Suction cups 42 are respectively provided on the lifting plate 41 near its two ends, so that the suction cups 42 can be installed in a balanced manner on the lifting plate 41. At the same time, the suction cups 42 are located between the support members 32 arranged at both ends of the support plate 31, specifically, the suction cups 42 and the support members 32 are located in the same straight line direction.

[0044] In this embodiment, both the support member 32 and the suction cup 42 are arranged upwards along the Z-axis, acting to position and adsorb the bottom surface of the product. The suction cup 42 is externally connected to a vacuum generator to achieve the function of vacuum adsorption. The adsorption component and the support component are integrated into one unit. On the one hand, this facilitates the installation of the leveling component on the fixed frame 1, saving unnecessary drive component arrangement; on the other hand, the support member 32 of the support component and the suction cup 42 of the adsorption component are located in the same straight line direction, and the installation positions of the support member 32 and the suction cup 42 are close. The point of action of the suction cup 42 on the bottom surface of the product is located between the points of action of the support member 32 on the bottom surface of the product, improving the leveling accuracy of the product.

[0045] Example 3

[0046] This embodiment optimizes a thin-film solar cell leveling and positioning mechanism based on the above embodiments, and in particular provides a specific implementation of a movable frame:

[0047] like Figure 3 As shown, the mobile frame 2 includes a frame body 21 and several transmission modules disposed on the frame body 21; a drive module connected to the transmission modules is disposed on the side of the frame body 21.

[0048] The transmission module includes a transmission shaft 22 and a number of rubber wheels 23 mounted on the transmission shaft 22 and spaced apart along its axial direction. When the transmission shaft 22 rotates, it drives the rubber wheels 23 to rotate, thereby realizing the function of conveying products.

[0049] The drive module can be a structure of motor and transmission chain to drive several drive shafts 22 to rotate synchronously.

[0050] The mobile frame 2 also includes several auxiliary lifting modules for driving its lifting and lowering. Each auxiliary lifting module includes an auxiliary plate 24 and a second driving component 25 connected to the auxiliary plate 24. The auxiliary plate 24 is connected to the frame body 21 to achieve balanced lifting and lowering of the mobile frame 2. The second driving component 25 can be an electric drive, a hydraulic drive, or a pneumatic drive. In this embodiment, the second driving component 25 is a pneumatic drive, specifically a cylinder. The second driving component 25 is mounted on the fixed frame 1 to achieve lifting and lowering of the mobile frame 2 relative to the fixed frame 1.

[0051] In this embodiment, the product can be transported on the mobile frame 2 via a transmission module. After the product is transported to the designated position on the mobile frame 2, the transmission module pauses to keep the product stationary. The designated position is understood to be the product located directly above the space where the first adjustment distance and the second adjustment distance are located, so as not to cause the product to collide with the leveling component when it descends with the mobile frame 2, thus enabling the mobile frame 2 to accurately transfer the product to the leveling component.
