Description

Technical Field

[0001] This disclosure relates to the field of photovoltaic glass processing equipment technology, and in particular to a photovoltaic glass cleaning device. Background Technology

[0002] The production process of photovoltaic raw glass requires sampling and appearance inspection. The inspection process includes sampling, slicing, cleaning and darkroom inspection. The cleaning process usually uses cleaning equipment.

[0003] A novel solar photovoltaic glass cleaning device (CN 220371739 U) is described in the prior art. It includes a movable plate with a cleaning mechanism mounted on its bottom. The cleaning mechanism comprises a second fixed plate and a first fixed plate, both slidably connected to the left and right sides of the bottom of the movable plate. An L-shaped plate is slidably connected to the top of the second fixed plate. This novel solar photovoltaic glass cleaning device, by setting up a cleaning mechanism, installs the first and second fixed plates on both sides of the photovoltaic module. A rotating threaded rod moves the cleaning roller downwards, making it flush with the photovoltaic glass. During cleaning, a motor drives a gear to rotate, causing the L-shaped plate to move forward or backward, thereby moving the movable plate to wipe the surface of the photovoltaic glass with the cleaning roller. A water pump draws water from a tank, spraying water onto the glass from several nozzles. This eliminates the need for manual cleaning and provides excellent cleaning results.

[0004] For photovoltaic (PV) glass wafers, an automated continuous washing process is typically used. This involves the gripper of the washing equipment removing a cleaned basket (containing the PV glass wafer) from the washing tank, and then placing another basket into the tank for further cleaning. However, during operation, it often happens that the gripper fails to remove the basket from the tank after its initial gripping action (a "blank grip"). This, coupled with the need to place another basket into the tank, can lead to collisions and damage to the PV glass wafers. In other words, a blank grip can disrupt normal production. Therefore, how to avoid blank grips in PV glass washing equipment that could disrupt normal production is a problem that those skilled in the art need to consider. Utility Model Content

[0005] One of the technical problems this disclosure aims to solve is how to avoid the issue mentioned above, where the gripper of the photovoltaic glass cleaning device makes an empty grip, thus affecting normal production.

[0006] To address the aforementioned technical problems, this disclosure provides a photovoltaic glass cleaning device, comprising: a cleaning tank; a vertical slide rail disposed on one side of the cleaning tank; a transfer vehicle including a cantilever, a slider, and a gripper, the cantilever being located above the cleaning tank, the gripper being located between the cantilever and the cleaning tank and suspended on the cantilever, one end of the cantilever being movably connected to the vertical slide rail via the slider, so that the gripper can lift the cleaning basket inside the cleaning tank; and an anti-air grabbing mechanism including a pressure sensor and a support plate, the support plate being connected to the slider and located below the cantilever, the pressure sensor being disposed on the support plate, the bottom surface of the cantilever being able to abut against the top surface of the pressure sensor and generate downward pressure on the pressure sensor, and determining whether the gripper will lift the cleaning basket based on the magnitude of the pressure.

[0007] In some embodiments, the washing tank includes a plurality of grooves for placing washing baskets, the plurality of grooves being distributed along the length direction of the washing tank, and a vertical slide rail being movably disposed on one side of the washing tank along the length direction of the washing tank so that a gripper can pick up the washing baskets in different grooves.

[0008] In some embodiments, the photovoltaic glass cleaning device disclosed herein further includes a horizontal slide, which is disposed above one side of the cleaning tank and has its length direction parallel to the length direction of the cleaning tank. The upper part of the vertical slide is slidably connected to the horizontal slide.

[0009] In some embodiments, the bottom end of the vertical slide is slidably connected to the outer wall of the cleaning tank.

[0010] In some embodiments, the air raid stun gun also includes an alarm connected to a pressure sensor.

[0011] In some embodiments, the slider includes a C-groove and a connecting plate, the connecting plate being connected to the bottom plate of the C-groove, a T-shaped slide bar being provided on the vertical slide rail, the C-groove being slidably disposed on the T-shaped slide bar, and the support plate and the cantilever being connected to the connecting plate.

[0012] In some embodiments, one end of the cantilever is connected to the connecting plate via a pin.

[0013] In some embodiments, the top of the T-shaped slider is provided with an upper stop.

[0014] In some embodiments, limit blocks are provided at both ends of the horizontal slide.

[0015] In some embodiments, the surface of the gripper is covered with an anti-slip material.

[0016] According to the above technical solution, this disclosure provides a photovoltaic glass cleaning device. After the gripper performs the gripping action, the pressure applied by the cantilever to the pressure sensor determines whether the gripper is gripping empty, thereby avoiding the problem of affecting normal production due to empty gripping. Multiple grooves and horizontal slides enable continuous cleaning operations, meeting process requirements while improving production efficiency. The cooperation of T-shaped slide bars and C-shaped grooves enables the sliding connection between the slider and the vertical slide. Stops, limit blocks, and anti-slip materials ensure safe production. Attached Figure Description

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0029] As mentioned in the background section above, photovoltaic glass wafers are typically cleaned using an automated continuous washing process. This involves the gripper of the washing equipment removing a cleaned basket (containing the photovoltaic glass wafer) from the washing tank, and then placing another basket into the tank for further cleaning. However, during operation, the gripper often fails to remove the basket from the tank after its initial gripping action (a "blank grip"). This results in the gripper then placing another basket into the tank, potentially causing the two baskets to collide and damage the glass wafer. In other words, a blank grip can disrupt normal production. To address this, the inventors of this application provide a photovoltaic glass cleaning device in one or more embodiments. After the gripper performs its gripping action, the device determines whether a blank grip has occurred based on the pressure applied by the cantilever to a pressure sensor, thus avoiding the disruption to normal production caused by blank grips. This solves one or more problems in the prior art.

[0030] To address the aforementioned technical problems, this utility model provides a photovoltaic glass cleaning device, such as... Figure 1 and Figure 2 As shown, it includes: a cleaning tank 1; a vertical slide 2, which is located on one side of the cleaning tank 1; a transfer vehicle, which includes a cantilever 3, a slider 4, and a gripper 5. The cantilever 3 is located above the cleaning tank 1, and the gripper 5 is located between the cantilever 3 and the cleaning tank 1 and is suspended on the cantilever 3. One end of the cantilever 3 is movably connected to the vertical slide 2 via the slider 4 so that the gripper 5 can pick up the cleaning basket 6 in the cleaning tank 1; and an anti-air grabbing mechanism, which includes a pressure sensor 7 and a support plate 8. The support plate 8 is connected to the slider 4 and located below the cantilever 3. The pressure sensor 7 is located on the support plate 8. The bottom surface of the cantilever 3 can abut against the top surface of the pressure sensor 7 and generate downward pressure on the pressure sensor 7. The gripper 5 is then used to determine whether to pick up the cleaning basket 6 based on the magnitude of the pressure.

[0031] Specifically, after the cleaning basket 6 containing the photovoltaic glass substrate is cleaned in the cleaning tank 1, the transfer vehicle performs a transfer action, that is: the cantilever 3 moves downward along the vertical slide 2 under the drive of the slider 4. After moving to the gripping position, the gripper 5 performs a gripping action to grab the cleaning basket 6. Then, the cantilever 3 moves upward along the vertical slide 2 under the drive of the slider 4. If the gripping is successful, the cantilever 3 is subjected to a downward pulling force due to the gravity of the cleaning basket 6. Since the cantilever 3 is fixed at one point, the cantilever 3 will generate a certain displacement downward around the connection point with the slider 4, thereby increasing the pressure on the pressure sensor 7. The pressure sensor 7 transmits the pressure value to the pressure sensing controller 16 of the photovoltaic glass cleaning device. The pressure sensing controller 16 determines whether the gripper 5 has successfully gripped the substrate based on the received pressure value. For example, the execution software within the pressure sensor controller 16 is set such that after the gripper 5 performs the gripping action and the cantilever 3 moves upward a certain distance, if the pressure value of the pressure sensor 7 is greater than or equal to a predetermined value (e.g., 10 Newtons), the gripping is considered successful; if it is less than the predetermined value (e.g., 10 Newtons), the gripping is considered a failure. If the gripping fails, the control system of the photovoltaic glass cleaning device instructs the gripper 5 to grip again. If both gripping attempts fail, the photovoltaic glass cleaning device may malfunction and needs to be shut down for maintenance.

[0032] Compared with the prior art, this disclosure provides a photovoltaic glass cleaning device. After the gripper 5 performs the gripping action, the pressure applied by the cantilever 3 to the pressure sensor 7 is used to determine whether the gripper 5 is gripping empty, thereby avoiding the problem of affecting normal production caused by empty gripping.

[0033] In some embodiments, such as Figure 1 As shown, the cleaning tank 1 includes multiple grooves 9 for placing cleaning baskets 6. These grooves 9 are distributed along the length of the cleaning tank 1. A vertical slide 2 is movably positioned on one side of the cleaning tank 1 along its length, allowing the gripper 5 to lift the cleaning baskets 6 from different grooves 9. Specifically, different cleaning solutions can be placed in different grooves 9 according to process requirements. By moving the vertical slide 2 along the length of the cleaning tank 1, the cleaning baskets 6 can be sequentially placed into different cleaning solutions for cleaning, ensuring effective cleaning. Simultaneously, the horizontal movement of the vertical slide 2 and the vertical movement of the cantilever 3 on the vertical slide 2 enable continuous cleaning operations.

[0034] In some embodiments, such as Figure 1As shown, the photovoltaic glass cleaning device of this application also includes a horizontal slide 10, which is disposed above one side of the cleaning tank 1 and its length direction is parallel to the length direction of the cleaning tank 1. The upper part of the vertical slide 2 is slidably connected to the horizontal slide 10. The horizontal slide 10 enables the vertical slide 2 to move along the length direction of the cleaning tank 1. Specifically, each end of the horizontal slide 10 is provided with a column connected to it, forming a stable structural system through the columns.

[0035] In some embodiments, the bottom end of the vertical slide 2 is slidably connected to the outer wall of the cleaning tank 1. This slidable connection between the vertical slide 2 and the side wall of the cleaning tank 1 makes the entire structural system more stable and reasonable, ensuring safety. Specifically, a slide rail can be provided along the length of the side wall of the cleaning tank 1, and the bottom end of the vertical slide 2 is slidably connected to the slide rail.

[0036] In some embodiments, such as Figure 1 As shown, the air raid grabbing mechanism also includes an alarm 11, which is connected to a pressure sensor. Specifically, the alarm 11 is connected to the pressure sensor through a pressure sensor controller 16. When the grabber 5 fails to grab twice in a row, the alarm 11 sounds an alarm to remind the staff that the equipment may be malfunctioning and needs to be stopped for maintenance.

[0037] In some embodiments, such as Figure 2 As shown, the slider 4 includes a C-shaped groove 12 and a connecting plate 13. The connecting plate 13 is connected to the bottom plate of the C-shaped groove 12. A T-shaped slider 14 is provided on the vertical slide rail 2, and the C-shaped groove 12 is slidably disposed on the T-shaped slider 14. The support plate 8 and the cantilever 3 are both connected to the connecting plate 13. The sliding connection between the slider 4 and the vertical slide rail 2 is achieved through the cooperation of the T-shaped slider 14 and the C-shaped groove 12. Specifically, a locking mechanism can also be provided in the C-shaped groove 12. When the gripper 5 grips the cleaning basket 6, during the movement of the vertical slide rail 2 on the horizontal slide rail 10, the locking mechanism can lock the C-shaped groove 12 onto the T-shaped slider 14. In addition, the cantilever 3 and the slider 4 are connected through the connecting plate 13.

[0038] In some embodiments, such as Figure 2 As shown, one end of the cantilever 3 is connected to the connecting plate 13 via a pin 15. The pin 15 enables the cantilever 3 to be hinged to the connecting plate 13, allowing the cantilever 3 to rotate downwards under the gravity of the cleaning basket 6, thereby applying greater pressure to the pressure sensor 7 and further ensuring the accuracy of determining whether the gripper 5 has successfully gripped the basket.

[0039] In some embodiments, an upper stop (not shown) is provided at the top of the T-shaped slide bar 14. The stop prevents the C-shaped groove 12 from sliding off the T-shaped slide bar 14, thus ensuring production safety.

[0040] In some embodiments, limit blocks (not shown in the figure) are provided at both ends of the horizontal slide 10. The limit blocks prevent the vertical slide 2 from sliding off the horizontal slide 10 and also ensure production safety.

[0041] In some embodiments, the surface of the gripper 5 is covered with an anti-slip material (not shown in the figure). The anti-slip material prevents the gripper 5 from slipping off the cleaning basket 6 after it grips the cleaning basket 6.

[0042] In summary, compared with the prior art, this disclosure provides a photovoltaic glass cleaning device. After the gripper 5 performs the gripping action, the pressure applied by the cantilever 3 to the pressure sensor 7 is used to determine whether the gripper 5 is gripping empty, thereby avoiding the problem of affecting normal production due to empty gripping. Multiple grooves 9 and horizontal slides 10 realize the continuous cleaning operation, which meets the process requirements and improves production efficiency. The cooperation of T-shaped slide bar 14 and C-shaped groove 12 realizes the sliding connection between slider 4 and vertical slide 2. The use of stops, limit blocks and anti-slip materials ensures safe production.
