AI Technical Summary
In solar cell production, it is difficult to balance the relationship between increasing the printing stage to improve efficiency and adjusting the position of the printing stage to ensure printing accuracy. This leads to unstable stage movement and affects the printing accuracy of the solar cells.
Independent first and second adjustment mechanisms are used to drive the first and second printing stages to perform translational and rotational movements respectively. The second printing stage, which is adjusted by rotation, serves as a reference to control the translational adjustment of the first printing stage, thereby reducing the load weight and inertia of the stage. The adjustment accuracy is improved by combining position measurement sensors and DD motors.
This technology enables rapid stabilization of the printing stage, reduces interference from printing stage position adjustments, and improves the accuracy and efficiency of solar cell printing.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of solar cell production equipment, and relates to a cell printing platform and printing device. Background Technology
[0002] Electrode printing is a critical process in solar cell manufacturing, and its quality directly affects cell performance. Excellent electrode printing can improve energy density, cycle life, and reduce self-discharge rate. Screen printing technology, due to its uniformity and precision, is widely used in large-scale production and is suitable for complex electrode structure designs.
[0003] To improve conversion and production efficiency, some manufacturers are trying to add printing stages to a single carrier to produce more solar cells simultaneously. For example... Figure 1 As shown, the printing table is mounted on a carrier, which is driven by a linear motor to reciprocate along the first direction on the frame. When two printing tables are set on the carrier, it cannot be guaranteed that the position of the solar cells on each printing table is aligned with the printing screen. Adjustment mechanisms are needed to adjust the position of each printing table to adjust the position of the solar cells on each printing table. These adjustment mechanisms have a certain weight, which increases the overall weight of the carrier. Under current high production rates, the carrier moves at extremely high speeds in the first direction, often exceeding 2.6 m / s. The high overall weight of the carrier will exacerbate its inertia during movement in the first direction, hindering rapid stabilization and consequently affecting the printing accuracy of the solar cells.
[0004] Therefore, how to balance the relationship between increasing the printing table to improve efficiency and adjusting the position of the printing table to ensure printing accuracy is a technical problem that urgently needs to be solved. Utility Model Content
[0005] The purpose of this application is to provide a battery cell printing platform and printing apparatus that can effectively balance the relationship between increasing efficiency by adding a printing table and adjusting the position of the printing table to ensure printing accuracy.
[0006] The purpose of this application is to achieve the following technical solution:
[0007] On one hand, this application proposes a solar cell printing platform, which includes a stage, a first adjustment mechanism, a second adjustment mechanism, a first printing table, and a second printing table, wherein:
[0008] The first printing table is independently mounted on the carrier via a first adjustment mechanism. The first adjustment mechanism is configured to drive the first printing table to translate in a first direction within a first horizontal plane and to drive the first printing table to translate in a second direction within a second horizontal plane. The first horizontal plane is higher than the second horizontal plane.
[0009] The second printing table is independently mounted on the carrier via a second adjustment mechanism, which is configured to drive the second printing table to rotate in the third horizontal plane.
[0010] The first printing table and the second printing table are arranged sequentially and independently on the carrier along the second direction. The bearing surfaces of the first printing table and the second printing table are coplanar and are used to support a battery cell to be printed.
[0011] In this application's battery cell printing platform, the first and second printing stages complement each other during position adjustment. The second printing stage, capable of rotational adjustment, first rotates to its correct position. Then, using the corrected second printing stage as a reference, the first printing stage, capable of translational adjustment, is controlled to perform translational adjustments in the first and second directions, thereby achieving position adjustment of the first and second printing stages on the battery cell printing platform. By reducing the number of adjustment mechanisms that control the translation and rotation of the same printing stage, the load weight of the platform (i.e., the overall load weight of the battery cell printing platform) is reduced, as is the inertia of the platform in the first direction. This allows the platform to stabilize quickly and without interfering with the position adjustment of the printing stages on the platform.
[0012] Optionally, the first adjustment mechanism includes a first drive source and a second drive source. The first drive source is connected to the first printing table and drives the first printing table to translate relative to the platform in a first horizontal plane along a first direction. The second drive source is connected to the first drive source and drives the first printing table to translate relative to the platform in a second horizontal plane along a second direction.
[0013] By setting two drive sources to drive the first printing table to translate in the first direction in the first horizontal plane and in the second direction in the second horizontal plane respectively, the adjustment of the first printing table in different directions can be controlled independently, which helps to improve the adjustment accuracy and reduce mutual interference when adjusting in the two directions.
[0014] Optionally, the first driving source includes a first driving power supply, a first stator and a first moving part, wherein the first driving power supply drives the first moving part to move on the first stator along a first direction;
[0015] The second driving source includes a second driving power supply, a second stator, and a second mover. The second driving power supply drives the second mover to move along a second direction on the second stator.
[0016] The system employs a power supply, stator, and mover drive mechanism, enabling rapid response to control commands and providing the necessary power to ensure smooth and efficient adjustment of the cell printing platform.
[0017] Optionally, the cell printing platform also includes a first position measuring sensor and a second position measuring sensor. The first position measuring sensor is installed on the movement path of the first mover to sense the first mover; the second position measuring sensor is installed on the movement path of the second mover to sense the second mover.
[0018] By setting position measurement sensors on the movement paths of the two movers respectively, the movement distance of the movers can be measured, which helps to improve the adjustment accuracy.
[0019] Optionally, the first drive source and the second drive source are set at a vertical interval, with the installation position of the first drive source being higher than that of the second drive source.
[0020] After the cell printing platform is installed on the frame of the cell printing device, the first printing table driven by the first drive source moves along the first direction, and the second printing table driven by the second drive source moves along the second direction. The cell printing platform needs to reciprocate at high speed along the first direction on the frame. The installation position of the first drive source is higher than the installation position of the second drive source. That is, the installation position of the second drive source is used to longitudinally isolate the movement of the first printing platform controlled by the first drive source in the first direction from the movement of the cell printing platform in the first direction. This can reduce the interference of the inertia of the cell printing platform when it reciprocates at high speed along the first direction on the first drive source when it adjusts the first printing platform in the first direction.
[0021] Optionally, the second adjustment mechanism is a DD motor, the drive end of which is connected to the second printing table and drives the second printing table to rotate in the third horizontal plane.
[0022] The second adjustment mechanism uses a DD motor, which has a compact structure, can respond quickly, and improves adjustment accuracy.
[0023] Optionally, the sum of the longitudinal heights of the stage and the first printing stage is H1, where 50mm < H1 < 80mm, and the sum of the longitudinal heights of the stage and the second printing stage is H2, where 50mm < H2 < 80mm.
[0024] When a cell printing device is equipped with two or more transversely moving cell printing platforms, the sum of the longitudinal heights of the control platform and the first printing platform (H1) and the sum of the longitudinal heights of the control platform and the second printing platform (H2) are both within the range of 50mm to 80mm. This can effectively solve the interference between the cell printing platforms during their transverse movements.
[0025] Optionally, a square slot is provided on the platform, and a first adjustment mechanism is nested in the square slot; and / or, a circular slot is provided on the platform, and a second adjustment mechanism is nested in the circular slot.
[0026] By setting a square slot on the platform and nesting the first adjustment mechanism within it, the longitudinal space occupied by the first adjustment mechanism can be reduced, making the platform with the first adjustment mechanism as thin as possible, and further improving the stability of the cell printing platform during reciprocating motion in the first direction. Similarly, by setting a circular slot on the platform and nesting the second adjustment mechanism within it, the longitudinal space occupied by the second adjustment mechanism can be reduced, making the platform with the second adjustment mechanism as thin as possible, and further improving the stability of the cell printing platform during reciprocating motion in the first direction.
[0027] Optionally, the cell printing platform also includes a lifting drive mechanism, the drive end of which is connected to the stage transmission and is used to drive the stage to move up and down longitudinally.
[0028] When there are two or more cell printing platforms on the cell printing device, the lifting drive mechanism is used to control the cell printing platforms to rise and fall in the longitudinal direction, which helps the cell printing platforms to avoid each other when they reciprocate along the first direction.
[0029] On the other hand, this application proposes a battery cell printing apparatus, which includes a frame, a translation drive mechanism, a screen printing mechanism, and at least two battery cell printing platforms as proposed in this application, wherein...
[0030] The screen printing mechanism is located above the frame. The screen printing mechanism includes a screen, a fourth drive source, and a fifth drive source. The fourth drive source is connected to the screen drive and drives the screen to rotate in the horizontal plane. The fifth drive source is connected to the screen drive and drives the screen to translate in the second direction.
[0031] The fixed end of the translation drive mechanism is set on the frame, and the drive end of the translation drive mechanism is connected to the platform of each cell printing platform. The translation drive mechanism drives the cell printing platform to translate along the first direction on the frame and pass under the screen printing mechanism.
[0032] The application proposes a cell printing apparatus that uses the cell printing platform proposed in this application, which reduces the inertia of the stage in the first direction, enabling the stage to stabilize quickly and without interfering with the position adjustment of the printing stage on the stage.

[0047] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this invention as detailed in the appended claims.
[0048] In the production process of photovoltaic cells, the silicon wafer to cell stage needs to go through the following stages: silicon wafer inspection (parameters such as appearance, thickness, resistivity, etc.), surface texturing, diffusion, cleaning, etching, anti-reflective coating, screen printing, drying, sintering, and electrical performance testing.
[0049] This application addresses the issue of balancing the number and precision of printing tables in the screen printing stage, and proposes a battery cell printing platform and printing device.
[0050] Firstly, this application proposes a battery cell printing platform 100, such as... Figure 1 , 2 As shown, the battery cell printing platform 100 includes a stage 1, a first adjustment mechanism 2, a second adjustment mechanism 3, a first printing table 4, and a second printing table 5, wherein:
[0051] The first printing table 4 is independently mounted on the platform 1 via the first adjustment mechanism 2. The first adjustment mechanism 2 is configured to drive the first printing table 4 to translate in a first direction within a first horizontal plane and to drive the first printing table 4 to translate in a second direction within a second horizontal plane. The first horizontal plane is higher than the second horizontal plane.
[0052] The second printing table 5 is independently mounted on the platform 1 via the second adjustment mechanism 3. The second adjustment mechanism 3 is configured to drive the second printing table 5 to rotate in the third horizontal plane.
[0053] The first printing table 4 and the second printing table 5 are arranged sequentially and independently on the carrier 1 along the second direction. The bearing surfaces of the first printing table 4 and the second printing table 5 are coplanar and are used to support a battery cell to be printed.
[0054] In this application, the first printing stage 4 and the second printing stage in the battery cell printing platform 100 complement each other during position adjustment. The second printing stage 5, which is capable of rotational adjustment, first rotates to the correct position. Then, using the corrected second printing stage 5 as a reference, the first printing stage 4, which is capable of translational adjustment, is controlled to perform translational adjustments in the first and second directions, thereby achieving position adjustment of the first printing stage 4 and the second printing stage 5 on the battery cell printing platform 100. By reducing the adjustment mechanisms that adjust the same printing stage for translation and rotation, the load weight of the platform 1 (i.e., the overall load weight of the battery cell printing platform 100) is reduced, and the inertia of the platform 1 in the first direction is reduced, enabling the platform 1 to stabilize quickly and without interfering with the position adjustment of the printing stages on the platform 1.
[0055] Optional, such as Figure 3As shown, the first adjustment mechanism 2 includes a first drive source 21 and a second drive source 22. The first drive source 21 is connected to the first printing table 4 and drives the first printing table 4 to move in a first direction relative to the platform 1 in a first horizontal plane. The second drive source 22 is connected to the first drive source 21 and drives the first printing table 4 to move in a second direction relative to the platform 1 in a second horizontal plane.
[0056] By setting two drive sources to drive the first printing table 4 to translate in the first direction in the first horizontal plane and in the second direction in the second horizontal plane respectively, the adjustment of the first printing table 4 in different directions can be controlled independently, which helps to improve the adjustment accuracy and reduce mutual interference when adjusting in the two directions.
[0057] Optional, such as Figure 4 As shown, the first driving source 21 includes a first driving power supply, a first stator 211 and a first mover 212. The first driving power supply drives the first mover 212 to move on the first stator 211 along a first direction. The second driving source 22 includes a second driving power supply, a second stator 221 and a second mover 222. The second driving power supply drives the second mover 222 to move on the second stator 221 along a second direction.
[0058] The drive system, which integrates power supply, stator, and mover, can quickly respond to control commands and provide the necessary power, ensuring that the adjustment of the cell printing platform 100 is smooth and efficient.
[0059] Optionally, the cell printing platform 100 also includes a first position measuring sensor and a second position measuring sensor (not shown in the figure). The first position measuring sensor is installed on the movement path of the first mover 212 and is used to sense the first mover 212. The second position measuring sensor is installed on the movement path of the second mover 222 and is used to sense the second mover 222.
[0060] By setting position measurement sensors on the movement paths of the two movers respectively, the movement distance of the movers can be measured, which helps to improve the adjustment accuracy.
[0061] Optional, such as Figure 4 As shown, the first drive source 21 and the second drive source 22 are arranged longitudinally at intervals, and the installation position of the first drive source 21 is higher than the installation position of the second drive source 22.
[0062] After the cell printing platform 100 is installed on the frame 9 of the cell printing device, the first printing table 4 driven by the first drive source 21 moves along the first direction, and the second printing table 5 driven by the second drive source 22 moves along the second direction. The cell printing platform 100 needs to reciprocate at high speed along the first direction on the frame 9, so that the installation position of the first drive source 21 is higher than the installation position of the second drive source 22. That is, by using the installation position of the second drive source 22, the movement of the first printing platform controlled by the first drive source 21 in the first direction is separated from the movement of the cell printing platform 100 in the first direction in the longitudinal direction. This can reduce the interference of the inertia of the cell printing platform 100 when it reciprocates at high speed along the first direction on the first drive source 21 when it adjusts the first printing platform in the first direction.
[0063] Optionally, the second adjustment mechanism 3 is a DD motor, the drive end of which is connected to the second printing table 5 and drives the second printing table 5 to rotate in the third horizontal plane.
[0064] The second adjustment mechanism 3 uses a DD motor, which has a compact structure, can respond quickly, and improves adjustment accuracy.
[0065] Optionally, the sum of the heights of the stage 1 and the first printing stage 4 in the longitudinal direction is H1, 50mm < H1 < 80mm, and the sum of the heights of the stage 1 and the second printing stage 5 in the longitudinal direction is H2, 50mm < H2 < 80mm.
[0066] like Figure 1 As shown, taking the second printing table 5 as an example, the height of the second printing table 5 in the longitudinal direction is h1, and the height of the platform 1 in the longitudinal direction is h2. The sum of the heights of the platform 1 and the second printing table 5 in the longitudinal direction, H2 (i.e., the sum of h1 and h2), needs to be between 50mm and 80mm to solve the interference between the battery cell printing platforms 100 during their staggered movements.
[0067] When the cell printing apparatus is equipped with two or more cell printing platforms 100 that move laterally in an alternating manner, the sum of the longitudinal heights of the control platform 1 and the first printing platform 4 is H1, and the sum of the longitudinal heights of the control platform 1 and the second printing platform 5 is H2, both of which are within the range of 50mm to 80mm. This can effectively solve the interference between the cell printing platforms 100 during their alternating movements.
[0068] Optional, such as Figure 5 As shown, a square slot 11 is provided on the platform 1, and a first adjustment mechanism 2 is nested in the square slot 11; and / or, a circular slot 12 is provided on the platform 1, and a second adjustment mechanism 3 is nested in the circular slot 12.
[0069] By providing a square slot 11 on the stage 1 and nesting the first adjustment mechanism 2 within it, the longitudinal space ratio of the first adjustment mechanism 2 can be reduced, making the stage 1 with the first adjustment mechanism 2 as thin as possible, further improving the stability of the cell printing platform 100 during reciprocating motion in the first direction. Similarly, by providing a circular slot 12 on the stage 1 and nesting the second adjustment mechanism 3 within it, the longitudinal space ratio of the second adjustment mechanism 3 can be reduced, making the stage 1 with the second adjustment mechanism 3 as thin as possible, further improving the stability of the cell printing platform 100 during reciprocating motion in the first direction.
[0070] Optionally, the cell printing platform 100 also includes a lifting drive mechanism 6, the drive end of which is connected to the stage 1 for driving the stage 1 to move up and down longitudinally. The lifting drive mechanism 6 can be an electric cylinder, a pneumatic cylinder, or a mechanism that combines a motor and a transmission mechanism to achieve linear drive.
[0071] When there are two or more battery cell printing platforms 100 on the battery cell printing device, the lifting drive mechanism 6 is used to control the battery cell printing platforms 100 to rise and fall in the longitudinal direction, which helps the battery cell printing platforms 100 to avoid each other when they reciprocate along the first direction.
[0072] On the other hand, this application proposes a battery cell printing apparatus, such as Figure 6 As shown, the solar cell printing apparatus includes a frame 9, a translation drive mechanism 7, a screen printing mechanism 8, and at least two solar cell printing platforms 100 as proposed in this application, wherein...
[0073] The screen printing mechanism 8 is located above the frame 9. The screen printing mechanism 8 includes a screen 81, a fourth drive source and a fifth drive source. The fourth drive source is connected to the screen 81 and drives the screen 81 to rotate in the horizontal plane. The fifth drive source is connected to the screen 81 and drives the screen 81 to translate in the second direction.
[0074] The fixed end of the translation drive mechanism 7 is set on the frame 9, and the drive end of the translation drive mechanism 7 is connected to the platform 1 of each battery cell printing platform 100. The translation drive mechanism 7 drives the battery cell printing platform 100 to translate along the first direction on the frame 9 and pass under the screen printing mechanism 81.
[0075] It should be noted that the structure of the translation drive mechanism 7 can be a mechanism composed of a motor, a synchronous pulley, and a synchronous belt, with each cell printing platform 100 fixedly installed at a different position on the synchronous belt. Alternatively, it can be a mechanism composed of a motor, a lead screw, and a nut, with each cell printing platform 100 fixedly mounted on a corresponding nut (the number of nuts corresponds to the number of cell printing platforms 100). It can also be a linear motor translation mechanism composed of a stator and a mover, with each cell printing platform 100 fixedly mounted on a corresponding mover (the number of nuts corresponds to the number of cell printing platforms 100). The structure of the translation drive mechanism 7 is not limited to the above mechanisms and can also be other mechanisms capable of achieving translation drive. Furthermore, the number of translation drive mechanisms 7 can be adjusted according to the number of cell printing platforms 100.
[0076] The fourth drive source can be a DD motor, or a mechanism that combines a motor and a transmission mechanism to perform rotary drive; the fifth drive source can be an electric cylinder, a pneumatic cylinder, or a mechanism that combines a motor and a transmission mechanism to perform linear drive.
[0077] The following is combined with Figure 6 The working principle of the battery cell printing platform 100 and battery cell printing apparatus of this application:
[0078] Figure 6 The battery cell printing apparatus shown has four battery cell printing platforms 100. All four battery cell printing platforms 100 can be driven by the translation drive mechanism 7 to move in a first direction on the frame 9. The screen printing mechanism is set at a position above the movement path of the four battery cell printing platforms 100. Each battery cell printing platform 100 includes two printing tables, namely the first printing table 4 and the second printing table 5. Each printing table carries a battery cell to be printed.
[0079] When a cell printing table moves along the first direction to below the screen printing mechanism 81, before the screen printing mechanism 81 performs screen printing on the cell to be printed on the cell printing table, it is necessary to determine whether to start adjusting the position of the cell to be printed based on the position information of the cell to be printed.
[0080] Figure 7 , 8 To illustrate two different states of the battery cells to be printed, for ease of explanation, the battery cells to be printed on the first printing station 4 are marked as 110, and the battery cells to be printed on the second printing station 5 are marked as 120. Furthermore, for clarity, Figure 7 , 8 The positional illustration of the cells to be printed in the image is an enlarged representation of tilt and offset; in actual production, the cells to be printed will not have excessive positional deviations.
[0081] likeFigure 7 As shown in (a), the battery cell 120 to be printed on the second printing table 5 is tilted to the right, and the distance between it and the battery cell 110 to be printed on the first printing table 4 is large. At this time, the second adjusting mechanism 3 is controlled to rotate the second printing table 5 counterclockwise, so that the battery cell 120 to be printed on the second printing table 5 is rotated to the correct position, as shown in (a). Figure 7 As shown in (b), the first adjustment mechanism is then controlled to adjust the battery sheet 110 to be printed on the first printing table 4 along the first direction and / or the second direction, so that the battery sheet 110 and the battery sheet 120 to be printed are parallel and aligned, as shown in (b). Figure 7 As shown in (c).
[0082] like Figure 8 As shown in (a), both the battery sheet 110 to be printed on the first printing table 4 and the battery sheet 120 to be printed on the second printing table 5 are tilted to the left, and the distance between them and the battery sheet 110 to be printed on the first printing table 4 is relatively large. At this time, the second adjusting mechanism 3 is controlled to rotate the second printing table 5 counterclockwise, so that the battery sheet 120 to be printed on the second printing table 5 is parallel to the battery sheet 110 to be printed. Figure 8 As shown in (b), the first adjustment mechanism is then controlled to adjust the battery sheet 110 to be printed on the first printing table 4 along the first direction and / or the second direction, so that the battery sheet 110 and the battery sheet 120 to be printed are parallel and aligned, as shown in (b). Figure 8 As shown in (c).
[0083] After the battery cells 110 and 120 to be printed are adjusted to be parallel and aligned, the screen printing mechanism 81 is adjusted by the fourth and fifth drive sources to align the screen 81 with the battery cells 110 and 120 to be printed, and then printing is performed on the battery cells 110 and 120 to be printed.
[0084] The printed cells will be carried by the corresponding cell printing platform 100 and continue to move along the first direction to the end of the frame 9 to be taken out. The cells to be printed will be loaded onto the cell printing platform 100 again. The cell printing platform 100 needs to move along the first direction again to below the screen printing mechanism 81. There will be interference between it and other cell printing platforms 100 that are moving in the opposite direction. At this time, the lifting drive mechanism 6 can be used to drive any cell printing platform 100 to rise and stagger them in the longitudinal direction.
[0085] The application proposes a cell printing apparatus that uses the cell printing platform 100 proposed in this application, which reduces the inertia of the stage 1 in the first direction, enabling the stage 1 to stabilize quickly and without interfering with the position adjustment of the printing table on the stage 1.
