Description

Technical Field

[0001] This utility model relates to the field of automated photovoltaic cell production technology, and in particular to a photovoltaic cell spacing transformation mechanism. Background Technology

[0002] With the rapid development of the photovoltaic industry, half-cell technology has become the mainstream process route in the industry due to its significant advantages in reducing internal losses and increasing the power of photovoltaic modules. In the half-cell stringing or layout process, there is often an excessively large and irregular initial spacing between the two half-cells from the upstream material, which needs to be adjusted to meet the requirements of subsequent processes.

[0003] In related technologies, two motors are used to drive the sizing components to sizing the solar cells. This makes the cell spacing adjustment mechanism more complex and costly. Furthermore, when sizing and adjusting the cell spacing, the sizing components need to undertake an excessively long travel distance, which significantly reduces the equipment cycle time and thus reduces production efficiency. At the same time, the excessive sliding distance of the solar cells on the conveyor belt not only increases the risk of cell positional deviation during transmission but also easily causes scratches on the surface of the solar cells, affecting product quality.

[0004] Therefore, there is an urgent need to design a photovoltaic cell spacing transformation mechanism to solve the above technical problems. Utility Model Content

[0015] As an optional technical solution for a photovoltaic cell spacing conversion mechanism, the first connecting component includes a first base, a first connecting plate, and a first locking member. The first base is connected to the alignment component, the first connecting plate is connected to the first base through the first locking member, and a first pressing space is formed between the first connecting plate and the first base. The first upper synchronous belt or the first lower synchronous belt is disposed in the first pressing space.

[0016] The second connecting assembly includes a second base, a second connecting plate, and a second locking member. The second base is connected to the conveyor belt assembly, the second connecting plate is connected to the second base through the second locking member, and a second pressing space is formed between the second connecting plate and the second base.

One end of the driving shaft passes through the first synchronous wheel and the second synchronous wheel in sequence, and the other end of the driving shaft is driven and connected to the output end of the driving motor. The driving shaft is configured to drive the first synchronous wheel and the second synchronous wheel to rotate synchronously.

[0022] As an optional technical solution for a photovoltaic cell spacing adjustment mechanism, the straightening component is provided with a rubber-coated bearing. The rubber-coated bearing is arranged on the side of the straightening component facing the cell on the corresponding conveyor belt component. The rubber-coated bearing is used to abut against the cell to straighten the cell position, and the rubber-coated bearing can rotate synchronously with the cell conveying.

[0023] The beneficial effects of this utility model include at least the following:

[0024] This invention provides a photovoltaic cell spacing changing mechanism, which includes at least two conveyor belt assemblies, at least two straightening assemblies, and a drive assembly. The conveyor belt assemblies are located at the straightening station and are used to transport the cells. The straightening assemblies are arranged on one side of the conveyor belt assemblies, and each conveyor belt assembly corresponds to one of the straightening assemblies. The drive assembly is driven to both the straightening assemblies and the conveyor belt assemblies, and is configured to drive the straightening assemblies to move towards each other and to drive the conveyor belt assemblies to move towards each other, thereby changing the cell spacing on the conveyor belt assemblies.

[0025] The above describes a method for achieving cell positioning by using a single drive component to simultaneously drive the conveyor belt assembly and the positioning assembly in opposite directions. When two cells enter the positioning station, the drive component is activated, and the two positioning components and two conveyor belt assemblies move synchronously towards each other. During this process, the conveyor belt assembly carries the cells towards the center, while the positioning components move synchronously towards the cells. This shortens the distance the cells travel relative to the conveyor belt assembly before reaching their target position. This reduces friction between the cells and the conveyor belt assembly, minimizing scratches and improving product quality. Furthermore, it reduces the travel distance of the positioning components, increasing production efficiency and cycle time. In addition, this invention uses a single drive component to simultaneously drive the conveyor belt assembly and positioning components in opposite directions, eliminating the need for independent drive systems for both. This simplifies the photovoltaic cell spacing adjustment mechanism and reduces manufacturing and maintenance costs. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0044] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] This embodiment provides a photovoltaic cell spacing adjustment mechanism, which has low cost and high production efficiency, while reducing the occurrence of scratches on the cells and improving product quality.

[0046] like Figures 1-2 As shown, the photovoltaic cell spacing changing mechanism mainly includes at least two conveyor belt assemblies 10, at least two straightening assemblies 20, and a drive assembly 30. The conveyor belt assemblies 10 are located at the straightening station and are used to transport the cells. The straightening assemblies 20 are arranged on one side of the conveyor belt assemblies 10, and each conveyor belt assembly 10 corresponds to one straightening assembly 20. The drive assembly 30 is driven by both the straightening assemblies 20 and the conveyor belt assemblies 10, and is configured to drive the straightening assemblies 20 to move towards each other and to drive the conveyor belt assemblies 10 to move towards each other, thereby changing the cell spacing on the conveyor belt assemblies 10.

[0047] Based on the above design, in this embodiment, a single drive component 30 simultaneously drives the conveyor belt assembly 10 and the sizing component 20 to move towards each other, thereby achieving the sizing of the solar cells. When two solar cells enter the sizing station, the drive component 30 is activated, and the two sizing components 20 and the two conveyor belt assemblies 10 move towards each other synchronously. During this process, the conveyor belt assembly 10 carries the solar cells toward the center, while the sizing component 20 moves synchronously toward the solar cells, thus shortening the distance the solar cells travel relative to the conveyor belt assembly 10 before reaching the target position. This reduces friction between the solar cells and the conveyor belt assembly 10, minimizing scratches on the solar cells and improving product quality. Furthermore, it reduces the travel distance of the sizing component 20, increasing production efficiency and cycle time. In addition, this embodiment uses a single drive component 30 to simultaneously drive the conveyor belt assembly 10 and the sizing component 20 to move towards each other, eliminating the need for independent drive systems for both, simplifying the photovoltaic cell spacing transformation mechanism, and reducing the manufacturing and maintenance costs of the equipment.

[0048] Optionally, the battery cell in this embodiment can be a half-size battery cell or a full-size battery cell.

[0049] like Figures 1-2 As shown, the drive assembly 30 in this embodiment includes a first synchronous belt 31, a second synchronous belt 32, a first synchronous pulley 33, and a second synchronous pulley 34. The first synchronous pulley 33 tensions the first synchronous belt 31 and defines the first synchronous belt 31 to move in opposite directions, namely the first upper synchronous belt 311 and the first lower synchronous belt 312. The second synchronous pulley 34 tensions the second synchronous belt 32 and defines the second synchronous belt 32 to move in opposite directions, namely the second upper synchronous belt 321 and the second lower synchronous belt 322.

[0050] In any pair of corresponding alignment components 20 and conveyor belt components 10, the alignment component 20 is connected to the first upper synchronous belt 311, and the conveyor belt component 10 is connected to the second upper synchronous belt 321. Alternatively, the alignment component 20 is connected to the first lower synchronous belt 312, and the conveyor belt component 10 is connected to the second lower synchronous belt 322. Both connection methods are feasible, depending on the overall layout space of the photovoltaic cell spacing transformation mechanism.

[0051] Specifically, based on the characteristics of the reverse motion of the first upper synchronous belt 311 and the first lower synchronous belt 312, and the reverse motion of the second upper synchronous belt 321 and the second lower synchronous belt 322, when the first synchronous pulley 33 and the second synchronous pulley 34 rotate, the first upper synchronous belt 311 and the first lower synchronous belt 312 reversely drive the two side alignment components 20 to move closer together, and the second upper synchronous belt 321 and the second lower synchronous belt 322 reversely drive the two side conveyor belt components 10 to move closer together, thereby achieving the alignment requirement of the solar cells. This eliminates the need for two sets of drive sources, simplifies the structure of the photovoltaic cell spacing transformation mechanism, and saves costs.

[0052] The first synchronous belt 31 and the second synchronous belt 32 are flexible bodies. When they are directly connected to the rigid alignment component 20 or the conveyor belt component 10, stress concentration can easily cause wear of the belt teeth or loosening of the connection.

[0053] Therefore, as Figures 1-2 As shown, the photovoltaic cell spacing transformation mechanism further includes at least two first connecting components 40 and at least two second connecting components 50. The first connecting components 40 are configured one-to-one with the straightening components 20, and the second connecting components 50 are configured one-to-one with the conveyor belt components 10. One end of the first connecting component 40 is connected to the straightening component 20, and the other end is connected to the first upper synchronous belt 311 or the first lower synchronous belt 312; one end of the second connecting component 50 is connected to the conveyor belt components 10, and the other end is connected to the second upper synchronous belt 321 or the second lower synchronous belt 322.

[0054] In this embodiment, by adding a rigid first connecting component 40 and a second connecting component 50 as transition components, the linear motion of the first synchronous belt 31 and the second synchronous belt 32 is smoothly transmitted to the load, avoiding stress concentration or loosening of the first synchronous belt 31 and the second synchronous belt 32.

[0055] Specifically, such as Figure 2 As shown, the first connecting component 40 in this embodiment includes a first base 41, a first connecting plate 42, and a first locking member (not shown in the figure). The first base 41 is connected to the alignment component 20, and the first connecting plate 42 is connected to the first base 41 via the first locking member, forming a first pressing space between the first connecting plate 42 and the first base 41. A first upper synchronous belt 311 or a first lower synchronous belt 312 is disposed within the first pressing space. This converts the tension of the first synchronous belt 31 into internal compressive stress in the first connecting component 40, improving the reliability of the connection. The size of the first pressing space can be adjusted using the first locking member to accommodate first synchronous belts 31 of different thicknesses. Furthermore, this structure is easy to assemble and disassemble; the first synchronous belt 31 can be replaced simply by loosening the first locking member, improving maintenance efficiency.

[0056] Similarly, the second connecting assembly 50 includes a second base 51, a second connecting plate 52, and a second locking member (not shown in the figure). The second base 51 is connected to the conveyor belt assembly 10, and the second connecting plate 52 is connected to the second base 51 via the second locking member. A second pressing space is formed between the second connecting plate 52 and the second base 51, and the second upper synchronous belt 321 or the second lower synchronous belt 322 is disposed in the second pressing space. This allows the tension of the second synchronous belt 32 to be converted into internal compressive stress in the second connecting assembly 50, improving the reliability of the connection. The size of the second pressing space can be adjusted using the second locking member, thereby adapting to second synchronous belts 32 of different thicknesses. Furthermore, this structure is easy to assemble and disassemble; the second synchronous belt 32 can be replaced simply by loosening the second locking member, improving maintenance efficiency.

[0057] For example, both the first locking element and the second locking element can be configured as screws.

[0058] Although both the first and second locking members can provide normal pressure, under high acceleration conditions, slight slippage may still occur between the first synchronous belt 31 and the first connecting plate 42, and between the second synchronous belt 32 and the second connecting plate 52, resulting in the accumulation of positional deviations.

[0059] Therefore, in this embodiment, anti-slip textures 421 are provided on the side of the first connecting plate 42 that contacts the first upper synchronous belt 311 or the first lower synchronous belt 312, and on the side of the second connecting plate 52 that contacts the second upper synchronous belt 321 or the second lower synchronous belt 322. This not only enhances the slip resistance of the first synchronous belt 31 and the second synchronous belt 32, improving stability and reliability, but also prevents excessive tightening force from damaging the first synchronous belt 31 and the second synchronous belt 32, thus extending their service life.

[0060] For example, the anti-slip texture 421 can be a microstructure such as transverse grooves, knurling, or dotted protrusions.

[0061] like Figure 2 As shown, the drive assembly 30 in this embodiment also includes a drive shaft 35 and a drive motor 36. One end of the drive shaft 35 passes through the first synchronous pulley 33 and the second synchronous pulley 34 in sequence, and the other end of the drive shaft 35 is driven to the output end of the drive motor 36. The drive shaft 35 is configured to drive the first synchronous pulley 33 and the second synchronous pulley 34 to rotate synchronously.

[0062] Specifically, one end of the drive shaft 35 passes coaxially through the shaft holes of the first synchronous pulley 33 and the second synchronous pulley 34 in sequence, and is fixed to both by a key or a shrink sleeve; the other end of the drive shaft 35 is directly connected to the output shaft of the drive motor 36 or connected through a coupling. After the drive motor 36 starts, the drive shaft 35 drives the first synchronous pulley 33 and the second synchronous pulley 34 to rotate synchronously.

[0063] In this embodiment, a single drive shaft 35 is connected in series with the first synchronous pulley 33 and the second synchronous pulley 34. The torque output by the drive motor 36 is rigidly transmitted to the first synchronous pulley 33 and the second synchronous pulley 34 through the drive shaft 35. The phase difference between the two is always zero and their angular velocities are equal. This can avoid the synchronization error caused by the setting of multiple drive sources in the prior art and ensure the consistency of the photovoltaic cell spacing change.

[0064] For example, the ratio of the diameter of the first synchronous pulley 33 to the diameter of the second synchronous pulley 34 is set to between 1.5 and 3.5. This ratio corresponds to the speed ratio of the alignment component 20 to the conveyor belt assembly 10. Preferably, this ratio is 2:1, at which point the displacement of the battery cells relative to the conveyor belt assembly 10 is minimized, ensuring both alignment effectiveness and reducing battery cell friction and scratches, thus improving the efficiency of cell spacing changes.

[0065] like Figures 1-2 As shown, the photovoltaic cell spacing adjustment mechanism in this embodiment further includes a support plate 60, a first slide rail 61, and a second slide rail 62. Both the first slide rail 61 and the second slide rail 62 are mounted on the support plate 60, are parallel to each other, and extend in the same direction as the cell alignment direction. The alignment component 20 is slidably connected to the first slide rail 61, and the conveyor belt component 10 is slidably connected to the second slide rail 62.

[0066] By setting the first slide rail 61 and the second slide rail 62, the motion friction resistance of the aligning component 20 and the conveyor belt component 10 is reduced, component wear is reduced, and service life is extended; at the same time, the guiding effect of the first slide rail 61 and the second slide rail 62 ensures the linearity of the motion, improves the positional accuracy, and avoids damage to the battery cells.

[0067] During rapid, toward-each-other movement of two solar cells, the cells may overshoot their target position due to inertia, leading to insufficient spacing between cells or even collision damage. Therefore, as Figure 1 As shown, a stop 63 is also provided on the support plate 60. The stop 63 is located at the axis of symmetry between the two conveyor belt assemblies 10. The stop 63 is configured to limit the battery cells on both sides.

[0068] Specifically, the stop 63 is preferably a vertical plate-like structure, and its installation position is precisely located on the axis of symmetry between the two conveyor belt assemblies 10. When the battery cells on both sides move towards the target position with the conveyor belt assemblies 10, the inner edge of the battery cell contacts the stop 63, thereby limiting the position of the battery cell and improving the alignment effect. At the same time, the stop 63, as a symmetry reference, ensures the symmetry of the stopping positions of the battery cells on both sides, further improving the consistency of the cell spacing. Since the stop 63 does not move with any moving parts, its positional accuracy can be maintained for a long time, unaffected by factors such as the stretching of the first synchronous belt 31 and the second synchronous belt 32.

[0069] For example, the stop 63 can be a plastic stop or a rubber-coated bearing with a bracket.

[0070] like Figures 1-2 As shown, the alignment component 20 in this embodiment is provided with a rubber-coated bearing 21. The rubber-coated bearing 21 is arranged on the side of the alignment component 20 facing the battery cell on the corresponding conveyor belt component 10. The rubber-coated bearing 21 is used to abut against the battery cell to align the position of the battery cell, and the rubber-coated bearing 21 can rotate synchronously with the conveying of the battery cell.

[0071] Specifically, the outer ring of the rubber-coated bearing 21 is wrapped with a flexible material (such as silicone or polyurethane), and its inner ring is rotatably mounted on the mounting bracket of the aligning assembly 20 via a spindle. The mounting bracket of the aligning assembly 20 is located on the first base 41. When the aligning assembly 20 moves toward the solar cell, the flexible outer layer of the rubber-coated bearing 21 abuts against the side of the solar cell, applying a aligning force to the solar cell. As the solar cell continues to move forward under the drive of the conveyor belt assembly 10, the frictional force causes the rubber-coated bearing 21 to roll synchronously. This rolling rotation transforms sliding friction into rolling friction, reducing resistance, protecting the solar cell, and making the aligning process smoother and improving aligning efficiency.

[0072] Optionally, multiple rubber-coated bearings 21 can be evenly spaced on the organizing component 20 according to actual needs. For example, two, three, four, or other numbers of rubber-coated bearings 21 can be provided.

[0073] like Figure 1 As shown, an incoming material assembly 70 is also provided at the upstream end of the regularization station of the photovoltaic cell spacing transformation mechanism. Its function is to receive the cells output from the upstream process and to stably and continuously transport the cells to the downstream conveyor belt assembly 10, thereby ensuring the continuity of the cell transmission path and the consistency of the movement state.

[0074] Specifically, the incoming material assembly 70 is installed on the upstream extension of the support plate 60 and is arranged collinearly with the downstream conveyor belt assembly 10 along the transmission direction of the battery cells. The transmission paths of the two are completely aligned to avoid the battery cells shifting during process connection.

[0075] It should be noted that the feeding assembly 70 and the conveyor belt assembly 10 in this embodiment have the same structure. Both use a motor to drive the belt to rotate, thereby realizing the purpose of transferring the battery cells from the feeding assembly 70 to the conveyor belt assembly 10.

[0076] For example, there are multiple material receiving components 70 and multiple conveyor belt components 10, and the material receiving components 70 and the conveyor belt components 10 are arranged in a one-to-one correspondence and on the same line.
