Battery piece bearing table and regularizing mechanism

Abstract

The application provides a battery piece bearing table and a regularizing mechanism. The bearing surface of the battery piece bearing table is provided with glue-avoiding hole rows in a first direction at intervals. Each glue-avoiding hole row comprises a plurality of glue-avoiding holes distributed in a second direction at intervals. When the battery piece is borne on the battery piece bearing table, each glue-avoiding hole is used for avoiding a glue point on the battery piece. The second direction is perpendicular to the first direction. The bearing surface of the battery piece bearing table is also provided with suction holes. The bearing surface of the battery piece bearing table of the application is provided with glue-avoiding hole rows and suction holes at the same time. The bearing surface can bear and suck the battery piece, and can also avoid the glue points on the battery piece through the glue-avoiding holes. Since the glue points are avoided through the glue-avoiding holes, the area between the two adjacent glue-avoiding holes can still bear the battery piece, so that the effective contact area of the bearing surface and the battery piece is larger. The way of processing the glue-avoiding holes on the bearing surface can also more easily ensure the flatness of the bearing surface, thereby improving the bearing effect of the battery piece bearing table on the battery piece.

Description

Technical Field

[0001] This application relates to the field of photovoltaic module production equipment, specifically a cell support platform and organizing mechanism. Background Technology

[0002] For grid-less solar cells, one stringing process involves first applying adhesive dots 101 (e.g., ...) to designated locations on the solar cell 100 using a solar cell adhesive applicator. Figure 1 (As shown), the solder ribbons are then strung together with the battery cells.

[0003] During or after the adhesive application process, the solar cells with adhesive dots on their lower surface need to be transferred to a solar cell support platform for the next step, such as straightening or inspection. To prevent the solar cell support platform from scraping against the adhesive dots on the lower surface of the solar cells, existing solar cell support platforms have several upward-protruding support strips 200 on their support surface (e.g., Figure 2 As shown, the printed solar cells are supported on the support strips 200, and each support strip 200 is located between two adjacent rows of adhesive dots on the solar cells. The area between two adjacent support strips 200 is used to avoid a row of adhesive dots.

[0004] Existing solar cell support platforms rely on upward-protruding support strips to support the solar cells. For solar cells with dense adhesive dots, the number of support strips on the solar cell support platform is large, the width of the support strips is narrow, and the spacing between adjacent support strips is small. The processed solar cell support platform is easily deformed, and it is difficult to ensure that the support surfaces of all support strips are on the same plane. Ultimately, this makes it difficult for the solar cells to be stably supported on the solar cell support platform. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a battery cell support platform, the detailed technical solution of which is as follows:

[0006] A battery cell support platform is used to support battery cells whose lower surface has been coated with adhesive. The lower surface of the battery cell has a number of adhesive dots, and each row of adhesive dots includes multiple spaced adhesive dots.

[0007] On the bearing surface of the battery cell support platform, there are several rows of adhesive-avoiding holes spaced apart along the first direction. Each row of adhesive-avoiding holes includes several adhesive-avoiding holes spaced apart along the second direction. When the battery cell is supported on the battery cell support platform, each adhesive-avoiding hole is used to avoid an adhesive dot on the battery cell. The second direction is perpendicular to the first direction.

[0008] Several adsorption holes are also provided on the bearing surface of the battery cell support platform.

[0009] The solar cell support platform provided in this application has both adhesive-avoiding holes and adsorption holes on its support surface. The support surface can both support and adsorb solar cells, and the adhesive-avoiding holes can avoid adhesive dots on the solar cells. Because the adhesive dots are avoided through the adhesive-avoiding holes, the area between two adjacent adhesive-avoiding holes can still support solar cells, making the effective contact area between the support surface and the solar cells larger. The method of processing adhesive-avoiding holes on the support surface also makes it easier to ensure the flatness of the support surface, thereby improving the support effect of the solar cell support platform on the solar cells and ensuring the support stability.

[0010] In some embodiments, the adhesive-avoiding hole is a through hole that penetrates the cell support platform, or the adhesive-avoiding hole is a blind hole that does not penetrate the cell support platform, and the depth of the blind hole is greater than the height of the adhesive dot.

[0011] Setting the adhesive-avoiding hole as a through hole that penetrates the cell support platform or a blind hole with a depth greater than the height of the adhesive dot can ensure that the adhesive dot is suspended in the adhesive-avoiding hole and prevent the adhesive dot from contacting the bottom of the adhesive-avoiding hole.

[0012] In some embodiments, the projected area of ​​the adhesive dots on the bearing surface is smaller than the projected area of ​​the adhesive avoidance holes on the bearing surface.

[0013] Ensure that the adhesive-avoiding hole can fully accommodate the adhesive dots, and prevent the adhesive dots from contacting the sidewall of the adhesive-avoiding hole.

[0014] In some embodiments, the adsorption holes are arranged in several rows at intervals along a first direction, and each row of adsorption holes includes several adsorption holes distributed at intervals along a second direction. The adsorption holes are staggered from the adhesive-avoiding holes. The battery cell support platform is provided with a gas path communicating with each adsorption hole, and the gas path is connected to an external vacuum generator.

[0015] Several rows of adsorption holes work together at different positions to adsorb the solar cells, ensuring stable adsorption and preventing damage due to uneven force. The vacuum generator evacuates air from the solar cell support platform, thereby generating adsorption force in the adsorption holes. The adsorption holes and adhesive avoidance holes are staggered, resulting in a more compact structure that effectively avoids densely packed adhesive dots while ensuring adsorption performance.

[0016] In some embodiments, at least one adhesive avoidance groove is provided on the bearing surface of the battery cell carrier platform. The adhesive avoidance groove extends along a second direction. When at least two adhesive avoidance grooves are provided, each adhesive avoidance groove is arranged at intervals along a first direction. Each adhesive avoidance groove is used to avoid at least one row of adhesive dots on the battery cell. The adhesive avoidance groove divides the bearing surface of the battery cell carrier platform into at least two bearing areas. Each bearing area has at least one row of adhesive avoidance holes and at least one adsorption hole on its bearing surface.

[0017] By setting adhesive-avoiding grooves on the bearing surface of the cell carrier platform to avoid at least one row of adhesive dots on the cell, the number of adhesive-avoiding holes can be reduced while ensuring the bearing effect of the cell, thereby reducing the structural complexity and cleaning difficulty of the cell carrier platform.

[0018] In some embodiments, the length of the cell support platform is smaller than the length of the cell, and / or the width of the cell support platform is smaller than the width of the cell; when the cell is supported on the cell support platform, some adhesive dots on the cell are located on the outside of the cell support platform.

[0019] By configuring the dimensions of the solar cell support platform in this way, the size of the platform is reduced, thus lowering its manufacturing cost. Furthermore, by allowing the ends of the solar cells supporting the platform to extend beyond the platform in either the length or width direction, the solar cell transfer device can lift the cells from below for transfer, reducing the risk of damage.

[0020] This application also provides a straightening mechanism, which includes a straightening drive unit and at least one cell support platform, wherein: the cell support platform is connected to the drive end of the straightening drive unit and is used to support the cell after the lower surface has been coated; the straightening drive unit is used to drive the cell support platform to translate and / or rotate in the horizontal plane to straighten the cell.

[0021] By driving the cell support platform to translate and / or rotate in the horizontal plane through the alignment drive unit, the alignment mechanism of this application realizes the alignment of the position and angle of the cell after the lower surface has been coated.

[0022] In some embodiments, the alignment drive unit includes a translation drive assembly and a rotation drive assembly, wherein: the rotation drive assembly is connected to a movable part of the translation drive assembly, and the cell support platform is connected to the movable part of the rotation drive assembly; the rotation drive assembly is used to drive the cell support platform to rotate in a horizontal plane; and the translation drive assembly is used to drive the cell support platform to translate along a first direction and / or a second direction.

[0023] The positioning and angle alignment of the battery cells are performed by the translation drive component and the rotation drive component respectively, which improves the alignment flexibility and alignment accuracy.

[0024] In some embodiments, the alignment mechanism includes at least two cell support platforms arranged side by side along a second direction, each cell support platform being used to support one cell.

[0025] When there are at least two cell support platforms, the sizing mechanism can simultaneously size at least two cells each time, thereby improving sizing efficiency.

[0026] In some embodiments, the spacing between the cell support platforms is configured to be adjustable.

[0027] By adjusting the spacing between the cell support platforms, the need for regularizing cells with different spacings can be met. Attached Figure Description

[0041] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0042] As described in the background section, existing solar cell support platforms rely on upward-protruding support strips to support the solar cells. For solar cells with dense adhesive dots, the number of support strips on the solar cell support platform is large, and the width of the support strips is narrow, and the spacing between adjacent support strips is small. The processed solar cell support platform is easily deformed, and it is difficult to ensure that the support surfaces of all support strips are on the same plane, which ultimately makes it difficult for the solar cells to be stably supported on the solar cell support platform.

[0043] Therefore, this application provides a battery cell support platform for supporting, such as Figure 1 The battery cell 100 shown has a number of adhesive dots applied to its lower surface. Each row of adhesive dots includes multiple spaced adhesive dots 101.

[0044] like Figures 3 to 6 As shown, the battery cell support platform 1 of this application has a plurality of glue-avoiding hole rows 11 spaced apart along a first direction (such as the X direction) on its support surface. Each glue-avoiding hole row 11 includes a plurality of glue-avoiding holes 12 spaced apart along a second direction (such as the Y direction), wherein the second direction is perpendicular to the first direction.

[0045] When the solar cell 100 is supported on the solar cell support platform 1, each adhesive avoidance hole 12 is used to avoid an adhesive dot 101 on the solar cell 100.

[0046] In addition, several adsorption holes 13 are provided on the bearing surface of the battery cell support platform 1.

[0047] The battery cell support platform 1 provided in this application has both adhesive-avoiding hole rows 11 and adsorption holes 13 on its support surface. The support surface can both support and adsorb the battery cell 100, and can also avoid adhesive dots 101 on the battery cell 100 through the adhesive-avoiding holes 12. Since the adhesive dots 101 are avoided through the adhesive-avoiding holes 12, the area between two adjacent adhesive-avoiding holes 12 can still support the battery cell 100, making the effective contact area between the support surface and the battery cell 100 larger. In addition, the way the adhesive-avoiding holes 12 are processed on the support surface makes it easier to ensure the flatness of the support surface, thereby improving the support effect of the battery cell support platform 1 on the battery cell 100 and ensuring the support stability.

[0048] like Figure 5 As shown, optionally, the adhesive-avoiding hole 12 is a blind hole that does not penetrate the cell support platform 1, and the depth of the blind hole is greater than the height of the adhesive dot 101. In this way, the adhesive dot can be suspended in the adhesive-avoiding hole 12, preventing the adhesive dot 101 from contacting the bottom of the adhesive-avoiding hole 12. Of course, the adhesive-avoiding hole 12 can also be a through hole that penetrates the cell support platform 1.

[0049] like Figure 6As shown, optionally, the projected area of ​​the adhesive dot 101 on the bearing surface is smaller than the projected area of ​​the adhesive-avoiding hole 12 on the bearing surface, thereby preventing the adhesive dot 101 from contacting the sidewall of the adhesive-avoiding hole 12.

[0050] like Figures 3 to 6 As shown, optionally, the adsorption holes 13 are arranged in several rows at intervals along a first direction (e.g., the X direction), and each row of adsorption holes 13 includes several adsorption holes 13 distributed at intervals along a second direction (e.g., the Y direction). The adsorption holes 13 are staggered from the adhesive-avoiding holes 12. The battery cell support platform 1 is provided with a gas passage communicating with each adsorption hole 13, and the gas passage is connected to an external vacuum generator.

[0051] Several rows of adsorption holes 13 work together at different positions to adsorb the battery cell 100, ensuring stable adsorption of the battery cell 100 and preventing damage to the battery cell 100 due to uneven force. The vacuum generator evacuates air from the air passage in the battery cell support platform 1, thereby causing the adsorption holes 13 to generate adsorption force to adsorb the battery cell 100. The adsorption holes 13 and the adhesive avoidance holes 12 are staggered, making the structure more compact and effectively avoiding densely arranged adhesive dots while ensuring adsorption effect.

[0052] like Figures 3 to 6 As shown, optionally, at least one adhesive avoidance groove 14 is also provided on the bearing surface of the battery cell support platform 1, and the adhesive avoidance groove 14 extends along a second direction (such as the Y direction). Each adhesive avoidance groove 14 is used to avoid at least one row of adhesive dots 101 on the battery cell 100.

[0053] By providing a non-adhesive groove 14 on the bearing surface of the cell carrier 1 to avoid at least one row of adhesive dots 101 on the cell 100, the number of non-adhesive holes 12 can be reduced while ensuring the bearing effect on the cell 100, thereby reducing the structural complexity and cleaning difficulty of the cell carrier 1.

[0054] To ensure that the solar cell 100 can be omnidirectionally adsorbed and fixed on the bearing surface of the solar cell carrier 1, when at least two adhesive-avoiding grooves 14 are provided (e.g., the two in the figure), each adhesive-avoiding groove 14 is arranged at intervals along a first direction (e.g., the X direction). The adhesive-avoiding grooves 14 divide the bearing surface of the solar cell carrier 1 into at least two (e.g., the three in the figure) bearing areas, and each bearing area has at least one row of adhesive-avoiding holes 11 and at least one adsorption hole 13 on its bearing surface.

[0055] like Figure 6 As shown, in one embodiment, the length of the battery cell support platform 1 is smaller than the length of the battery cell 100, and the width of the battery cell support platform 1 is smaller than the width of the battery cell 100. When the battery cell 100 is supported on the battery cell support platform 1, some adhesive dots on the battery cell 100 are located on the outer side of the battery cell support platform 1.

[0056] This configuration, on the one hand, can further reduce the risk of the adhesive dots on the solar cell 100 being scratched by the solar cell support platform 1. On the other hand, since both ends of the solar cell 100, which is supported on the solar cell support platform 1, extend out of the solar cell support platform 1 in both the length and width directions, the solar cell transfer device can lift the solar cell 100 from below to transfer the solar cell 100, thereby reducing the risk of damage to the solar cell 100.

[0057] Of course, in other embodiments, the length of the battery cell support platform 1 may be set to be less than the length of the battery cell 100, so that both ends of the battery cell 100 extend out of the battery cell support platform 1 along the length direction. Alternatively, the width of the battery cell support platform 1 may be set to be less than the width of the battery cell 100, so that both ends of the battery cell 100 extend out of the battery cell support platform 1 along the width direction.

[0058] This application also provides a regulating mechanism. For example... Figure 7 As shown, the alignment mechanism includes an alignment drive unit 2 and at least one cell support platform 1, wherein the cell support platform 1 is connected to the drive end of the alignment drive unit 2 and is used to support the cell 100 whose lower surface has been coated with adhesive. The alignment drive unit is used to drive the cell support platform 1 to translate and / or rotate in the horizontal plane to align the cell 100.

[0059] By driving the cell support platform 1 to translate and / or rotate in the horizontal plane through the alignment drive unit 2, the alignment mechanism of this application realizes the alignment of the position and angle of the cell 100 after the lower surface has been coated, which facilitates the subsequent processing of the cell 100.

[0060] like Figure 7 As shown, optionally, the alignment drive unit 2 includes a translation drive assembly 21 and a rotation drive assembly 22, wherein: the rotation drive assembly 22 is connected to the movable part of the translation drive assembly 21, and the battery cell support platform 1 is connected to the movable part of the rotation drive assembly 22. The rotation drive assembly 22 is used to drive the battery cell support platform 1 to rotate in the horizontal plane. The translation drive assembly 21 is used to drive the battery cell support platform 1 to translate along a first direction (such as the X direction) and / or a second direction (such as the Y direction).

[0061] When the translation drive assembly 21 only needs to adjust the position of the battery cell 100 in the first or second direction, it can employ various existing linear drive mechanisms. For example, a lead screw drive mechanism consisting of a motor, lead screw, and nut, or a synchronous belt drive mechanism consisting of a motor, synchronous pulley, and synchronous belt. When the translation drive assembly 21 needs to adjust the position of the battery cell 100 in both the first and second directions, it can consist of a first translation drive unit and a second translation drive unit. The first translation drive unit is used to adjust the position of the battery cell 100 in the first direction, and the second translation drive unit is used to adjust the position of the battery cell 100 in the second direction. Both the first and second translation drive units can employ various existing linear drive mechanisms.

[0062] The rotary drive assembly 22 can be any existing rotary drive module capable of driving the battery cell support platform 1 to rotate in the horizontal plane, such as a DD motor, a servo motor, or a complete structure consisting of a servo hydraulic cylinder and a crank connecting rod.

[0063] Optionally, the organizing mechanism of this application includes at least two solar cell support platforms 1 arranged side by side along a second direction (such as the Y direction), each solar cell support platform 1 being used to support one solar cell 100.

[0064] The cell support platform 1 is configured to have at least two, so that the straightening mechanism of this application can straighten at least two cells 100 at the same time each time, thereby improving the straightening efficiency.

[0065] For example, Figure 7 The straightening mechanism in the illustrated embodiment includes three battery cell support platforms 1 arranged side by side along the second direction, so that it can simultaneously straighten three battery cells 100 each time.

[0066] Optionally, the spacing between the cell support platforms 1 is configured to be adjustable.

[0067] By adjusting the spacing between the battery cell support platforms 1, the alignment mechanism of this application can meet the alignment requirements of battery cells 100 with different spacings.

[0068] In one optional embodiment, a horizontal mounting plate is connected to the drive end of the alignment drive unit 2. The mounting plate has oblong holes extending in the second direction, each corresponding to a cell support 1. Each cell support 1 is mounted on the mounting plate in an adjustable position via bolts passing through the corresponding oblong holes.

[0069] This application provides a sufficiently detailed and specific description.

The scope of protection claimed in this application is defined by the claims, not by the above descriptions in the embodiments. Without contradiction, some optional components in one embodiment can also be used in another embodiment, and some preferred structures of the same component in one embodiment are also applicable to another embodiment.
