Description

Technical Field

[0001] This invention relates to the field of solar cell experimental workbench technology, specifically to an experimental workbench device for high-efficiency solar cells. Background Technology

[0002] Before solar cells can be put into use, they must undergo a variety of experiments. Among these experiments, the most significant issue is the loss of open-circuit voltage. It is currently suspected that the laser scanning process during manufacturing caused micro-cracks and other damage to the film layer. The damaged film layer reduces its protective capabilities and increases the rate of efficiency degradation, thus leading to a decrease in the open-circuit voltage at the assembly stage.

The jet pipe corresponds to the baffle and is connected to the air intake pipe. The guide groove is opened on the side of the baffle close to the solar cell, and the bottom of the guide groove is an inclined surface.

[0010] Furthermore, a recycling tank is provided on one side of the main body of the workbench. The bottom of the corrosion tank, the cleaning tank and the drying tank are all connected to a drain pipe. The drain pipe extends into the inside of the recycling tank. A control valve is installed at the bottom of the drain pipe. A recycling bucket is installed inside the recycling tank.

[0011] Furthermore, the top of the workbench body is equipped with control button one and control button two. Control button one is electrically connected to telescopic cylinder one, and control button two is electrically connected to the horizontal push assembly.

[0013] By employing the above technical solution, the present invention provides an experimental workbench device for high-efficiency solar cells, which has at least the following beneficial effects: 1. The present invention, through the setting of the battery fixing component, facilitates the expansion of the width of the solar cell placement position when it is necessary to take the solar cell out of the battery fixing box, while pushing the solar cell up, reducing the difficulty of taking the solar cell out of the battery fixing box, and reducing the possibility of damage caused by the solar cell colliding with the battery fixing box during the taking out and placing.

[0014] 2.

[0015] 3. The present invention, through the setting of the jet pipe and guide groove, can not only increase the force required when the solar cell is moved and tilted, and reduce the possibility of damage to the solar cell from collision with the baffle when it is picked up and placed, but also use airflow to promote the detachment of experimental reagents from the solar cell, thereby reducing the amount of water required for subsequent cleaning of the solar cell.

[0016] 4. By using baffles and guide grooves, this invention can provide a larger airflow to the upper half of the solar cell and a smaller airflow to the lower half of the solar cell when the distance between the solar cell and the baffles on both sides is different. This makes the torque of the airflow blowing towards the solar cell from both sides similar, thereby improving the stability of the solar cell after being blown by the airflow from both sides when the baffles on both sides move at different distances.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 To reduce the difficulty of retrieving and placing batteries from the battery holder and minimize the possibility of collisions during battery handling, please refer to... Figures 1-2 This embodiment proposes an experimental workbench device for high-efficiency solar cells, including a workbench body 1. The top of the workbench body 1 is provided with a feeding rack 2, an etching tank 3, a cleaning tank 4, and a drying tank 5. The etching tank 3 is provided with a battery fixing assembly 6. The bottom of the feeding rack 2 is equipped with an airflow positioning assembly 7. The battery fixing assembly 6 includes a concave frame 61, a baffle 62, a horizontal pushing assembly 63, and an upward pushing assembly 64. The two ends of the concave frame 61 are respectively fixed to the two outermost baffles 62. Two adjacent baffles 62 form a group. The solar cell 12 is placed between a group of baffles 62. The upward pushing assembly 64 is fixed on the concave frame 61. The two horizontal pushing assemblies 63 are respectively fixed to one of the baffles 62 in the same group.

[0021] In use, one of the baffles 62 on the left is baffle A, and the one on the right is baffle B. When it is necessary to fix the solar cell 12, one of the horizontal pushing components 63 pushes all the baffles A to the left, and the other horizontal pushing component 63 pushes all the baffles B to the right, thus increasing the distance between the two baffles 62 in the same group. When it is necessary to put the solar cell 12 into the battery fixing component 6, the movable end of the upward pushing component 64 rises to its highest position, at which point the solar cell 12 is placed between baffles A and B, and finally the bottom of the solar cell 12 is supported by the upward pushing component 64. When it is necessary to remove the solar cell 12 from the battery fixing component 6, the movable end of the upward pushing component 64 rises to its highest position, at which point the solar cell 12 is removed from between baffles A and B. When it is necessary to fix the solar panel 12, the horizontal pushing component 63 pushes the A panel and the B panel to move in opposite directions, reducing the distance between the A panel and the B panel until the A panel and the B panel clamp the solar panel 12. This makes it easier to expand the width of the solar panel 12 placement position when it is necessary to take the solar panel 12 out of the battery fixing box. At the same time, it pushes the solar panel 12 up, reducing the difficulty of taking the solar panel 12 out of the battery fixing box, and reducing the possibility of damage caused by the solar panel colliding with the battery fixing box during the taking out and placing process.

[0022] To increase the distance between the two baffles 62 during solar cell handling and reduce the possibility of damage to the solar cells during handling, refer to... Figure 2The lateral push assembly 63 includes a fixed plate 631, a ball screw 632, a motor 633, and a lateral push frame 634. The fixed plate 631 is fixedly connected to the outermost baffle 62. The frame of the ball screw 632 is fixedly connected to the fixed plate 631. The motor 633 is fixed to the frame of the ball screw 632. The output end of the motor 633 is fixed to the screw of the ball screw 632. The lateral push frame 634 is fixed to the nut of the ball screw 632. The two baffles 62 of the set are respectively fixed to the two lateral push frames 634.

[0023] When using, Figure 2 Taking the perspective as an example, when it is necessary to pick up or put down the solar cell, the upper horizontal push component 63 drives plate B to move to the right, and the lower horizontal push component 63 drives plate A to move to the left, thereby increasing the distance between the two baffles 62 in the same group. This makes it easier to pick up or put down the solar cell between the two baffles 62, reducing the possibility of damage from contact between the solar cell and the baffles 62 on both sides when picking up or putting down the solar cell.

[0024] To further reduce the possibility of damage to solar cells during handling, refer to Figure 2 The push-up assembly 64 includes a telescopic cylinder 641, a movable plate 642, a support column 643, and a support plate 644. The telescopic cylinder 641 is fixed on the concave frame 61, the movable plate 642 is fixed on the movable end of the telescopic cylinder 641, the number of support columns 643 corresponds to the number of baffles 62, the support columns 643 are fixed on the side of the movable plate 642 away from the telescopic cylinder 641, and the support plate 644 is fixed to the support column 643.

[0025] When picking up or placing the solar cell, the horizontal push assembly 63 pushes the distance between plate A and plate B to increase, while the telescopic cylinder 641 extends, pushing the moving plate 642, support column 643 and support plate 644 to rise. By moving a short distance, the solar cell can be placed between the two baffles 62, thus completing the picking up and placing of the solar cell.

[0026] To achieve the goal of automating the placement of solar cells into corrosion tank 3 and improve the automation level of solar cell experiments, refer to... Figure 1The bottom of the feeding rack 2 is fixedly connected to a telescopic cylinder 8, the bottom of which is fixedly connected to a lifting rope 9, and the bottom of which is fixedly connected to a hook 10. The battery fixing assembly 6 is fixedly connected to a lifting ring 11 that is compatible with the hook 10. A recycling tank 13 is provided on one side of the workbench body 1. The bottoms of the corrosion tank 3, the cleaning tank 4, and the drying tank 5 are all connected to a drain pipe 14, which extends into the inside of the recycling tank 13. A control valve 15 is installed at the bottom of the drain pipe 14. A recycling bucket 16 is installed inside the recycling tank 13. A control button 17 and a control button 2 18 are installed on the top of the workbench body 1. The control button 17 is electrically connected to the telescopic cylinder 8, and the control button 2 18 is electrically connected to the horizontal push assembly 63. The top of the workbench body 1 is provided with a first transfer area 19 and a second transfer area 20. The first transfer area 19 is located at the end of the workbench body 1 near the corrosion tank 3, and the second transfer area 20 is located on the side of the workbench body 1 near the drying tank 5.

[0027] In use, place the solar cell 12 into the battery fixing assembly 6, then place the battery fixing assembly 6 in the first transfer area 19. Hook 10 onto the lifting ring 11 above the battery fixing assembly 6 placed in the first transfer area 19. Press control button 17, which will retract the telescopic cylinder 8 to lift the battery fixing assembly 6. The discharge rack 2 will then move the battery fixing assembly 6 along the length of the workbench body 1 until it reaches the designated experimental pool. Press control button 17 again to lower the battery fixing assembly 6, allowing it to enter the experimental pool. Repeat this process sequentially. In this activity, experimental reagents are placed in corrosion tank 3, the battery body is washed with water in cleaning tank 4, and the battery body is dried in drying tank 5. When the battery body is placed in, control button 2 18 is pressed, and the horizontal push assembly 63 moves the baffle, increasing the distance between the baffles 62 in the same group. When the battery needs to be fixed, control button 2 18 is pressed again to reverse the movement, reducing the spacing between the plates, making the clamping tighter and less prone to loosening. This facilitates moving the solar cell 12 to the designated position for processing as needed, realizing the function of automatically driving the entire battery device to the designated position.

[0028] Example 2 To further improve the stability of solar cell 12 during placement and removal, refer to Figures 1-3 Based on Embodiment 1, the airflow positioning component 7 includes an air intake pipe 71, an air jet pipe 72, and a guide groove 73. The bottom of the air intake pipe 71 is closed, and the top of the air intake pipe 71 passes through the material feeding rack 2. The air jet pipe 72 corresponds to the baffle 62 and is connected to the air intake pipe 71. The guide groove 73 is opened on the side of the baffle 62 near the solar cell 12, and the bottom of the guide groove 73 is an inclined surface.

[0029] In use, the top of the air intake pipe 71 is connected to an air pipe, and air is continuously sprayed from the jet pipe 72 downwards onto the battery fixing assembly 6 and the solar cell 12. The airflow from the jet pipe 72 is sprayed onto the baffle 62 in an inclined direction, and then blocked by the baffle 62 and changed direction to flow onto the solar cell 12. The airflow pushes the solar cell 12 from both sides, which not only increases the force required when the solar cell 12 is moved and tilted, reducing the possibility of the solar cell 12 being tilted and damaged by collision with the baffle 62 when it is picked up and placed, but also promotes the removal of experimental drugs from the solar cell 12, reducing the amount of water required for subsequent cleaning of the solar cell.

[0030] When the distances that plates A and B move are different, resulting in different distances between the two baffles 62 and the solar cell 12 in the middle, when the airflow blows towards the baffle 62 that is closer to the solar cell 12 along the inclined direction, the airflow contacts the higher position of the baffle 62, and then blows towards the higher position of the solar cell 12 along the guide groove 73 at the higher position of the baffle 62. At this time, because the airflow moves a shorter distance, the airflow pushes the solar cell 12 with greater force, and the position where the airflow pushes the solar cell 12 is a longer distance from the bottom of the solar cell 12.

[0031] When the airflow is blown towards the baffle 62, which is farther away from the solar cell 12, along the inclined direction, the airflow comes into contact with the lower position of the baffle 62, and then blows towards the lower position of the solar cell 12 along the guide groove 73 at the lower position of the baffle 62. At this time, because the airflow has traveled a long distance, the force of the airflow pushing the solar cell 12 is small, and the distance between the position where the airflow pushes the solar cell 12 and the bottom of the solar cell 12 is short.

[0032] Combining the two different situations above, when the distance between the solar cell 12 and the baffles 62 on both sides is different, a larger airflow can be provided to the upper half of the solar cell 12, and a smaller airflow can be provided to the lower half of the solar cell 12. This makes the torque of the airflow blowing towards the solar cell 12 from both sides similar, thereby improving the stability of the solar cell 12 after being blown by the airflow from both sides when the baffles 62 on both sides move at different distances.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
