Description

Technical Field

[0001] This application relates to the field of solar panel sandblasting, and in particular to a solar panel sandblasting device. Background Technology

[0002] In the manufacturing process of new energy batteries (such as lithium-ion batteries and fuel cells), stainless steel battery panels (such as current collectors, casing components, and electrode plates) play a crucial role. Their surface treatment quality, including cleanliness, roughness, microstructure, and residual stress state, directly determines the stability of the electrochemical reaction interface inside the battery, electrolyte wettability, coating adhesion, and even the performance (such as energy density and cycle life) and safety of the final battery product. Therefore, efficient, stable, and high-quality pretreatment of stainless steel battery panels is one of the key steps in improving the overall quality of the battery.

[0003] Currently, the mainstream surface treatment methods for stainless steel solar panels in the industry include mechanical polishing, chemical treatment (such as pickling and passivation), and sandblasting (also known as shot peening). Among these, sandblasting technology has become one of the most widely used technologies in the field of stainless steel solar panel surface pretreatment due to its significant advantages, such as high processing efficiency, relatively low overall cost, better environmental performance (especially dry sandblasting), and the ability to effectively improve the mechanical properties of the material surface (such as increasing surface hardness and introducing beneficial compressive stress). The sandblasting process uses high-speed jet abrasive to impact the material surface, which can effectively remove oxide layers and oil stains, form a uniform and controllable roughness, and optimize the surface stress distribution, providing an ideal foundation for subsequent coating or assembly processes.

[0004] However, existing stainless steel solar panel sandblasting equipment and processes still face significant technical bottlenecks that hinder efficiency improvements in large-scale, high-frequency mass production scenarios. These bottlenecks primarily manifest in poor stability and high wear and tear of the tracked guiding system, easy replacement of the solar panel holding mechanism, low reliability and easy replacement of the solar panel holding mechanism, and unstable processing accuracy of the solar panels. How to solve these problems and improve the accuracy and efficiency of solar panel sandblasting is a question that those skilled in the art need to consider. Summary of the Invention

[0005] To address the problems in the prior art, this application provides a solar panel sandblasting device with higher precision and efficiency.

[0006] This application provides a solar panel sandblasting device, which includes a conveying mechanism, a pressure roller mechanism, and a sandblasting mechanism. The conveying mechanism includes a drive roller, several conveyor belts, and several limiting belts. The conveyor belts and limiting belts are respectively driven by the drive roller. The drive roller has several recessed annular limiting grooves on its rotating circumferential surface. The several conveyor belts and limiting belts are respectively disposed in different limiting grooves. The conveyor belts are used to drive the solar panel along a first direction. The conveyor belts and limiting belts are spaced apart along a second direction perpendicular to the first direction, and there is a height difference between the conveyor belts and limiting belts to limit the solar panel. The pressure roller mechanism includes a pressure roller drive assembly and at least two pressure rods. The pressure rods are located on the same side of the several conveyor belts and limiting belts and extend along the second direction, used to limit the solar panel to the surface of the conveyor belts. The pressure rods are detachably connected to the pressure roller drive assembly via couplings. The sandblasting mechanism includes a spray gun, and the sandblasting point area of ​​the spray gun is configured to be located between the two pressure rods along the first direction.

[0007] Understandably, the conveyor belt and the limiting belt are driven by the drive roller to enable continuous movement of the conveyor belt and the limiting belt and to convey the solar panels along the first direction. The limiting groove is located on the rotating circumference of the drive roller and is a concave ring shape, so that the conveyor belt and the limiting belt are continuously limited by the limiting groove when the drive roller rotates continuously, greatly reducing the risk of the conveyor belt and the limiting belt deviating. Several conveyor belts and several limiting belts are respectively set in different limiting grooves and are spaced apart along the second direction. The position of the conveyor belt and the limiting belt along the second direction is limited by different limiting grooves, which ensures that the conveyor belt and the limiting belt can rotate continuously along the first direction while preventing them from deviating along the second direction, maintaining good conveying accuracy and reducing the frequency of downtime maintenance. There is a height difference between the conveyor belts and the limiting belts spaced apart along the second direction. The space formed by this height difference can accommodate the solar panels for limiting the solar panels, ensuring that the solar panels can be conveyed along the first direction, while preventing the solar panels from deviating or misaligning, maintaining good conveying accuracy. The pressure bars, located on the same side of the conveyor belt and the limiting belt, confine the solar panels to the surface of the conveyor belt. Simultaneously, the sandblasting point of the spray gun is positioned between the two pressure bars, ensuring the solar panels are well-fixed during sandblasting. This prevents the panels from being blown away and shifting abnormally, and also avoids instability in the panel's movement during sandblasting, ensuring uniform sandblasting and thus guaranteeing the precision of the sandblasting process. The pressure bars are detachably connected to the pressure roller drive assembly via a coupling, improving the efficiency of pressure bar assembly and disassembly and reducing maintenance time for the solar panel sandblasting equipment.

[0008] In one embodiment, each conveyor belt is provided with a limiting belt on both opposite sides along the second direction, the thickness of the limiting belt being greater than the thickness of the conveyor belt; the pressure bar includes a main rod and a plurality of thickened rings arranged at intervals around the outside of the main rod, the thickened rings being arranged corresponding to the conveyor belt and at least partially located between the conveyor belt and the limiting belt along the second direction.

[0009] Understandably, the conveyor belt has limiting strips on both sides, and these strips are thicker. This serves two purposes: firstly, to limit the movement of the solar panels during processing and to prevent them from veering off course; secondly, the increased thickness of the limiting strips enhances their durability. The thickened rings, positioned corresponding to the conveyor belt, further compress the solar panels on its surface, improving processing accuracy. Additionally, the areas on the pressure bars with thickened rings are typically near the sandblasting point of the spray gun; these rings improve the overall durability of the pressure bars, reduce maintenance cycles, and increase overall processing efficiency.

[0010] In one embodiment, there is a gap between adjacent conveyor belts and limiting belts, the conveyor belts are provided with several through holes, and the limiting belts are continuous and flat.

[0011] Understandably, the through holes in the conveyor belt and the gaps between adjacent conveyor belts and limiting belts facilitate the rapid removal of abrasive material used in the sandblasting process, preventing abrasive accumulation from negatively impacting the sandblasting process. During sandblasting, the limiting belt, not covered by the solar panels, can be directly hit by the sandblasting; designing the limiting belt as a continuous, flat structure enhances its durability. The conveyor belt, being covered by the solar panels, faces a lower risk of being directly hit by the sandblasting; therefore, it is designed with through holes to facilitate rapid abrasive removal.

[0012] In one embodiment, the conveying mechanism includes two drive rollers spaced apart along a first direction. The two drive rollers have limiting grooves of the same position and number. The conveyor belt and the limiting belt respectively surround the two drive rollers and form a loop that is connected end to end. The conveying mechanism also includes a plurality of limiting rollers. The limiting rollers extend along a second direction and have thickened areas and ordinary areas spaced apart in sequence. The thickened areas are provided corresponding to the conveyor belt, and the ordinary areas are provided corresponding to the limiting belt.

[0013] Understandably, the two drive rollers have identical limiting slots in both position and number. The conveyor belt and the limiting belt cooperate with the two drive rollers to form a ring. Each piece of the conveyor belt and each limiting belt corresponds to the two limiting slots on the two drive rollers, ensuring that the conveyor belt and the limiting belt can rotate continuously with almost no deviation during rotation. The limiting rollers provide support and / or limit the conveyor belt and the limiting belt. The thickened area of ​​the limiting roller corresponds to the conveyor belt, and the normal area corresponds to the limiting belt. The thickness of the thickened area is greater than the thickness of the normal area to achieve uniform support for the conveyor belt and the limiting belt, minimizing the risk of sagging or deviation.

[0014] In one embodiment, the conveying mechanism further includes a tensioning assembly, which includes a plurality of tensioning components that tension the conveyor belt and the limiting belt respectively. The tensioning components include a tensioning connecting frame, a tensioning pushing part, and an elastic element. The tensioning connecting frame is configured to be fixedly installed and located on one side of the conveyor belt or the limiting belt. The tensioning pushing part is slidably connected to the tensioning connecting frame. The elastic element is disposed between the tensioning connecting frame and the tensioning pushing part and is used to drive the tensioning pushing part to squeeze the conveyor belt or the limiting belt to achieve tension.

[0015] Understandably, several tensioning components tension the conveyor belt and the limiting belt respectively, and the tensioning process can be continuously and adaptively adjusted through elastic elements; this maintains the tension of the conveyor belt and the limiting belt, maintains the accuracy of the conveyor belt and the limiting belt, extends the service life of the conveyor belt and the limiting belt, and reduces the maintenance or replacement cycle.

[0016] In one embodiment, the conveying mechanism further includes a thickness detection component, which is located upstream of the sandblasting mechanism along a first direction and is suspended above the conveyor belt to obtain the thickness parameters of the solar panels on the conveyor belt.

[0017] Understandably, if solar panels are stacked, some surfaces will inevitably show processing abnormalities during the sandblasting process. Installing a thickness detection component upstream of the conveyor belt to monitor the thickness parameters of the solar panels will prevent this. When panels are stacked, at least two panels overlap along the thickness direction, resulting in an excessively large thickness parameter. By installing the thickness detection component, potential stacking can be detected promptly, allowing for timely intervention to eliminate potential problems and maintain the required processing accuracy.

[0018] In one embodiment, the pressure roller mechanism further includes a driven component, a pressure rod is drivenly connected to the pressure roller drive component, and the pressure rod is rotatably connected to the driven component; the pressure rod is disposed between the pressure roller drive component and the driven component along a second direction, and each of the two ends of the pressure rod spaced apart along the second direction is detachably connected to the pressure roller drive component and the driven component respectively through a coupling.

[0019] Understandably, the two ends of the pressure rod are connected to the pressure roller drive assembly and the driven assembly, respectively. The pressure roller drive assembly is the active end that outputs rotational torque, while the driven assembly is the passive end that maintains rotation. Fixing both ends makes the rotation of the pressure rod smoother. Simultaneously, each end of the pressure rod is detachably connected to the pressure roller drive assembly and the driven assembly via a coupling, allowing for quick assembly and disassembly during equipment maintenance. This reduces equipment maintenance time and costs, increases the effective usable time of the solar panel sandblasting equipment, and ultimately improves production efficiency.

[0020] In one embodiment, the solar panel sandblasting equipment has a sandblasting processing space, and the sandblasting mechanism is located within the sandblasting processing space; the pressure roller drive assembly includes a transmission rod, a sealing plate, and at least two sealing rings, at least a portion of the transmission rod is located within the sandblasting processing space and connected to the pressure rod via a coupling, and the sealing plate and at least two sealing rings are both located within the sandblasting processing space; an annular groove is provided on the outer periphery of the transmission rod, the sealing plate is sleeved on the outer periphery of the transmission rod and engaged in the annular groove, and at least two sealing rings are sequentially sleeved on the outer periphery of the transmission rod.

[0021] Understandably, the sandblasting mechanism, located within the sandblasting processing space, is used to sandblast the solar panels. This space contains a large amount of abrasive material due to the sandblasting process, some of which may seep into the pressure roller drive assembly, damaging its related drive structure. By installing at least two sealing rings, most of the abrasive material can be effectively isolated. Furthermore, to prevent further seepage due to sealing ring failure or poor sealing, a sealing plate is fitted around the outer circumference of the drive rod. This sealing plate engages with an annular groove on the outer circumference of the drive rod, further preventing abrasive seepage into the pressure roller drive assembly. This double-layer protective structure reduces the probability of abrasive seepage into the pressure roller drive assembly, thus reducing the likelihood of damage. This decreases downtime for maintenance and increases the effective usability of the solar panel sandblasting equipment, ultimately improving production efficiency.

[0022] In one embodiment, the pressure roller drive assembly has a pressurized cavity, a sealing plate is located at the junction of the sandblasting space and the pressurized cavity, and a transmission rod passes through the pressurized cavity and extends into the sandblasting space; the pressure roller mechanism also has a pressurized hole, which communicates with the pressurized cavity and is used to apply a positive pressure to the pressurized cavity that is greater than the air pressure in the sandblasting space.

[0023] Understandably, the pressurized cavity is separated from the sandblasting space by a sealing plate. Theoretically, the sealing structure composed of the sealing plate and at least two sealing rings can prevent sand from entering the drive structure of the pressure roller mechanism. However, in actual use, it is difficult to maintain a high level of sealing effect of the sealing plate and sealing rings. Adding a pressurized cavity at the rear end of the sealing structure formed by the sealing plate and sealing rings, and applying a positive pressure (specifically a slight positive pressure) greater than the air pressure in the sandblasting space through a connecting pressurized hole, can further prevent sand from entering the drive structure of the pressure roller mechanism. This further reduces the probability of damage to the pressure roller mechanism, decreases the number of downtime maintenance operations for the solar panel sandblasting equipment, increases the effective usable time of the solar panel sandblasting equipment, and ultimately improves production efficiency.

[0024] In one embodiment, the sandblasting mechanism further includes a sandblasting bracket, a quick-release link, and a swing rod. The quick-release link and the swing rod are detachably connected. Each side of the sandblasting bracket is detachably connected to a quick-release link. The sandblasting bracket has two spaced mounting holes along a first direction. The spray gun is fitted into the mounting holes and is inclined relative to the first direction.

[0025] Understandably, the spray gun is tilted within the mounting hole via a sandblasting bracket, facilitating pre-adjustment and determination of the sandblasting impact area to ensure sandblasting precision. Both sides of the sandblasting bracket are connected to quick-release rods, providing better stability during swinging. The detachable connection between the sandblasting bracket and the quick-release rods allows for height adjustment, and the detachable connection between the quick-release rods and the swing arm facilitates rapid installation and disassembly, reducing assembly and disassembly time, lowering equipment maintenance costs, increasing the effective usable time of the solar panel sandblasting equipment, and ultimately improving production efficiency.

Detailed Implementation

[0036] The following is in conjunction with the appendix Figures 1 to 9 This application will be described in further detail below.

[0037] In typical continuous conveyor sandblasting equipment, stainless steel solar panels are usually carried and guided through the sandblasting area by wear-resistant tracks (or chain guides). However, the track guiding structure design of existing equipment often has shortcomings. Under the combined effects of high-speed operation and high-intensity abrasive impact, the tracks are prone to guide deviation, misalignment, or abnormal wear. This deviation can not only cause the solar panel conveying trajectory to become inaccurate, affecting the uniformity of sandblasting, but more importantly, the abnormal wear rate of the tracks is extremely fast. According to actual production feedback, such critical consumables need to be replaced on average every two weeks; frequent downtime for track replacement not only directly increases equipment maintenance costs, but also seriously interrupts the continuous production process, significantly reducing the effective operating time of the equipment and overall production efficiency. On the other hand, stainless steel solar panels are usually characterized by large area, thin thickness, and relatively light weight; during the sandblasting process, the high-speed jet of abrasive and the auxiliary airflow generate a strong force. To prevent solar panels from being "blown away" or shifting position by airflow in the sandblasting area, mechanical holding devices such as pressure rollers can be used to hold the panels firmly during the sandblasting process. While this solves the positioning problem to some extent, the pressure rollers themselves are exposed to the harsh sandblasting environment, inevitably leading to problems such as rapid wear on the roller surface and sand ingress into the roller mechanism. As another type of high-wear component, the pressure rollers also face the need for frequent replacement. Replacing the pressure rollers not only incurs additional spare parts costs, but the replacement process also requires machine downtime, further squeezing valuable production time. Coupled with the downtime for track replacement, these two factors together hinder the improvement of overall production line efficiency.

[0038] Therefore, although sandblasting is a highly efficient and preferred solution for the surface treatment of stainless steel solar panels, general sandblasting equipment has significant drawbacks in two major areas: the high frequency and unplanned replacement of the track guiding system, and the reliance on easily damaged holding devices (pressure rollers) leading to external downtime for maintenance. These problems directly result in decreased equipment operational stability, shortened effective production time, and increased maintenance costs, ultimately severely restricting the production efficiency of the stainless steel solar panel sandblasting process and failing to meet the growing demand for large-scale, high-stability, and low-cost manufacturing in the new energy industry. Therefore, there is an urgent need to develop a new type of sandblasting equipment and method that can effectively solve the problem of abnormal track wear, reduce or avoid the use of easily damaged holding components, thereby significantly improving the continuous operation efficiency and production efficiency of the sandblasting process.

[0039] This application provides a solar panel sandblasting equipment with higher precision and efficiency. All vulnerable structures in the solar panel sandblasting equipment are designed to be stable and durable, which can significantly reduce the occurrence of abnormal wear and tear. Some structures are designed to be easy to disassemble, which reduces the frequency of maintenance and the time of each maintenance, increases the effective working time of the solar panel sandblasting equipment per unit time, and improves production efficiency.

[0040] The technical solutions in the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of the present invention, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of the present invention without creative effort are also within the protection scope of the present invention.

[0041] like Figures 1 to 3 As shown in the figure, this application provides a solar panel sandblasting device, which includes a housing 11, a conveying mechanism 12, a pressure roller mechanism 13, a sandblasting mechanism 14, and a sand recovery mechanism 15. The housing 11 serves as the main body supporting and covering the solar panel sandblasting device. The conveying mechanism 12, the pressure roller mechanism 13, the sandblasting mechanism 14, and the sand recovery mechanism 15 are all located in the housing 11 and supported or covered by the housing 11. The housing 11 defines a sandblasting processing space 111. The sandblasting mechanism 14 is mainly located in the sandblasting processing space 111 and performs sandblasting in the sandblasting processing space 111 to ensure that the sand does not seep out as much as possible. The conveying mechanism 12 passes through the sandblasting processing space 111 along its conveying direction to convey unprocessed solar panels. The solar panels are transported to the sandblasting processing space 111 for processing, and then transported outside the sandblasting processing space 111 for further processing. Multiple sand-proof curtains can be provided on the path of the conveying mechanism 12 to prevent sand from seeping out. At least part of the pressure roller mechanism 13 is located in the sandblasting processing space 111 and is used to cooperate with the conveying mechanism 12 to press the solar panels, ensuring that the posture and position of the solar panels are roughly stable when they are sandblasted. The sand recovery mechanism 15 is used to recover the sand, which facilitates centralized processing or reuse of the sand.

[0042] Those skilled in the art will understand that "solar panel (especially stainless steel solar panel)" refers to key thin-plate stainless steel components (such as current collectors, casing components, and electrode plates) used in the manufacture of new energy batteries (such as lithium-ion batteries and fuel cells), which have the physical characteristics of large area, relatively thin thickness, and light weight. Before assembly or coating, this component requires surface sandblasting pretreatment to achieve specific cleanliness, roughness, and microstructure requirements, thereby ensuring the electrochemical performance and lifespan of the battery. During continuous sandblasting, the solar panel, as the transported and positioned processing object, requires stable and efficient surface treatment, which is a crucial step in mass production.

[0043] Further integration Figures 4 to 6As shown, in one embodiment, the conveying mechanism 12 includes a drive roller 1211, a plurality of conveyor belts 1212 and a plurality of limiting belts 1213. The conveyor belts 1212 and the limiting belts 1213 are respectively driven and engaged with the drive roller 1211. The rotating circumferential surface of the drive roller 1211 has a plurality of recessed annular limiting grooves 1214. The plurality of conveyor belts 1212 and the plurality of limiting belts 1213 are respectively disposed in different limiting grooves 1214. The conveyor belts 1212 are used to drive the solar panel to move along the first direction X. The conveyor belts 1212 and the limiting belts 1213 are spaced apart along the second direction Y perpendicular to the first direction X. The conveyor belts 1212 and the limiting belts 1213 have a height difference to limit the solar panel. The pressure roller mechanism 13 includes a pressure roller drive assembly 131 and at least two pressure rods 133. The pressure rods 133 are located on the same side of a plurality of conveyor belts 1212 and a plurality of limiting belts 1213 and extend along a second direction Y, for confining the solar panel on the surface of the conveyor belts 1212. The plurality of pressure rods 133 are detachably connected to the pressure roller drive assembly 131 via couplings 134. The sandblasting mechanism 14 includes a spray gun 141, the sandblasting point area of ​​which is configured to be located between the two pressure rods 133 along a first direction X.

[0044] Understandably, the conveyor belt 1212 and the limiting belt 1213 are respectively driven and cooperate with the drive roller 1211 to enable the conveyor belt 1212 and the limiting belt 1213 to move continuously and convey the solar panel along the first direction X; the limiting groove 1214 is located on the rotating circumferential surface of the drive roller 1211 and is in the shape of a concave ring, so that when the drive roller 1211 rotates continuously, the conveyor belt 1212 and the limiting belt 1213 can be continuously limited by the limiting groove 1214, which greatly reduces the risk of the conveyor belt 1212 and the limiting belt 1213 shifting. Several conveyor belts 1212 and several limiting belts 1213 are respectively disposed in different limiting grooves 1214 and spaced apart along the second direction Y. The conveyor belts 1212 and limiting belts 1213 are each limited in position along the second direction Y by different limiting grooves 1214, ensuring that the conveyor belts 1212 and limiting belts 1213 can rotate continuously along the first direction X while preventing them from deviating along the second direction Y, maintaining good conveying accuracy and reducing the frequency of downtime maintenance. There is a height difference between the conveyor belts 1212 and limiting belts 1213 spaced apart along the second direction Y. The space formed by this height difference can accommodate the solar panels and limit their position, ensuring that the solar panels can be conveyed along the first direction X, while preventing the solar panels from deviating or misaligning, maintaining good conveying accuracy. The pressure bar 133, located on the same side of the conveyor belt 1212 and the limiting belt 1213, can confine the solar panel to the surface of the conveyor belt 1212. Simultaneously, the sandblasting point of the spray gun 141 is located between the two pressure bars 133, ensuring that the solar panel is well fixed during sandblasting. This prevents the solar panel from being blown away and causing abnormal displacement, and also avoids affecting the uniformity of sandblasting due to unstable movement of the solar panel during the sandblasting process, thus ensuring the accuracy of the sandblasting process. The pressure bar 133 is detachably connected to the pressure roller drive assembly 131 via a coupling 134, improving the efficiency of pressure bar assembly and disassembly and reducing the maintenance time of the solar panel sandblasting equipment.

[0045] That is, the solar panel sandblasting equipment provided in this application embodiment can achieve stable conveying and positioning of solar panels, and achieve stable sandblasting processing of solar panels. At the same time, the conveyor belt 1212 (or limiting belt 1213) and the drive roller 1211 cooperate through the limiting groove 1214, so that the conveying mechanism 12 has better stability, reliability and durability; the pressure rod 133, which can cooperate with the conveyor belt 1212 and the limiting belt 1213, further ensures the stability of the solar panel during the conveying and sandblasting process; the spray gun 141, which makes the sandblasting landing area located between the pressure rods 133, can hold the solar panel under the pressure rods 133 during the sandblasting process, avoiding the solar panel from being blown away as much as possible, and ensuring the accuracy and stability of the solar panel sandblasting processing.

[0046] Further integration Figures 3 to 6As shown, in one embodiment, the conveying mechanism 12 includes a transmission assembly 121, a limiting assembly 122, a tensioning assembly 123, and a thickness detection assembly 124. The transmission assembly 121 includes two transmission rollers 1211, a plurality of conveyor belts 1212, and a plurality of limiting belts 1213. The two transmission rollers 1211 are respectively connected to the housing 11 and are configured to rotate. At least one transmission roller 1211 is configured as a drive shaft that is driven and connected to a drive structure (e.g., a motor, not described in detail) and is rotatable. The other transmission roller 1211 can be a drive shaft or a driven shaft. The plurality of conveyor belts 1212 and the plurality of limiting belts 1213 rotate continuously around the two transmission rollers 1211. The limiting assembly 122 includes a linkage rod 1225 and several limiting rollers 1220. The limiting rollers 1220 are respectively connected to the machine housing 11 or to the linkage rod 1225, and are used to limit the several conveyor belts 1212 and several limiting belts 1213 to prevent the several conveyor belts 1212 and several limiting belts 1213 from deviating during rotation or from excessively sagging due to their own weight, which would affect accuracy. The tensioning assembly 123 includes a tension fixing rod 1231 and several tensioning components 1232. The tension fixing rod 1231 is fixedly connected to the machine housing 11 for positioning. The several tensioning components 123 are respectively fixedly connected to the tension fixing rod 1231, and the several tensioning components 1232 respectively tension the conveyor belts 1212 and the limiting belts 1213. The thickness detection component 124 includes a detection bracket 1241 and a detection sensor 1242. The detection sensor 1242 is connected to the housing 11 through the detection bracket 1241. The detection sensor 1242 is located upstream of the transmission component 121 and is used to detect the thickness parameters of the incoming solar panel.

[0047] In this embodiment, the drive roller 1211 is generally cylindrical in shape and is arranged parallel to the second direction Y. The rotation axis of the drive roller 1211 is generally parallel to the second direction Y. A limiting groove 1214 is provided on the circumferential surface of the drive roller 1211 around the rotation axis. The limiting groove 1214 is recessed towards the interior of the drive roller 1211, and the recess depth is generally uniform. Multiple limiting grooves 1214 are provided on the drive roller 1211, and the multiple limiting grooves 1214 are spaced apart along the rotation axis direction of the drive roller 1211. Adjacent limiting grooves 1214 are separated by groove shoulders 1215. The limiting grooves 1214 can be formed during the integral molding process of the drive roller 1211, or they can be manufactured by additive or subtractive processes after the drive roller 1211 is substantially formed; details are omitted here.

[0048] In this embodiment, the conveyor belt 1212 and the limiting belt 1213 extend mainly along the first direction X (the remaining portion surrounds the drive roller 1211); one side of each conveyor belt 1212 is disposed in a limiting groove 1214 of a drive roller 1211, and the other side is disposed in a limiting groove 1214 of another drive roller 1211. The two limiting grooves 1214 on both sides of a conveyor belt 1212 are spaced apart along the first direction X and arranged side by side along the second direction Y, ensuring that each conveyor belt 1212 extends approximately along the first direction X; similarly, one side of each limiting belt 1213 is disposed in a limiting groove 1214 of a drive roller 1211, and the other side is disposed in a limiting groove 1214 of another drive roller 1211. The two limiting grooves 1214 on both sides of a limiting belt 1213 are spaced apart along the first direction X and arranged side by side along the second direction Y, ensuring that each limiting belt 1213 extends approximately along the first direction X.

[0049] Further integration Figures 4 to 6 As shown, in one embodiment, the conveying mechanism 12 includes two drive rollers 1211 spaced apart along a first direction X. The two drive rollers 1211 have limiting grooves 1214 in the same position and number. The conveyor belt 1212 and the limiting belt 1213 respectively surround the two drive rollers 1211 and each form a loop that is connected end to end.

[0050] Understandably, the two drive rollers 1211 are provided with the same number and position of limiting grooves 1214. The conveyor belt 1212 and the limiting belt 1213 are wound in a ring with the two drive rollers 1211. Each conveyor belt 1212 and each limiting belt 1213 corresponds to the position of the two limiting grooves 1214 on the two drive rollers 1211, so that the conveyor belt 1212 and the limiting belt 1213 can rotate continuously during the rotation process with almost no deviation.

[0051] In one embodiment, a limiting belt 1213 is provided between two adjacent conveyor belts 1212, and a plurality of conveyor belts 1212 and a plurality of limiting belts 1213 are arranged alternately and at intervals along the second direction Y.

[0052] In one embodiment, each conveyor belt 1212 has a limiting band 1213 on both opposite sides along the second direction Y, and the thickness of the limiting band 1213 is greater than the thickness of the conveyor belt 1212. Specifically, the conveyor belt 1212 has a bearing surface (upper surface) for carrying solar panels, and the upper wall of the limiting band 1213, which is located on the same side as the bearing surface, is higher than the bearing surface along the direction of gravity. The two sides of the solar panel disposed on the bearing surface are limited by the side walls of the limiting band 1213.

[0053] Understandably, both sides of the conveyor belt 1212 are equipped with limiting strips 1213, and the limiting strips 1213 are thicker. On the one hand, they are used to limit the solar panels to prevent them from deviating during processing; on the other hand, the increased thickness of the limiting strips 1213 enhances their durability. The thickened ring 1332, corresponding to the conveyor belt 1212, can further press the solar panels located on the surface of the conveyor belt 1212, further improving processing accuracy.

[0054] In one embodiment, a gap 1216 exists between adjacent conveyor belts 1212 and limiting belts 1213. The conveyor belts 1212 have several through holes 1217, and the limiting belts 1213 have a continuous, flat structure. Specifically, a shoulder 1215 exists between every two adjacent limiting grooves 1214, thus creating a gap 1216 between the conveyor belts 1212 and the limiting belts 1213 located in the corresponding two adjacent limiting grooves 1214.

[0055] Understandably, the through holes 1217 and gaps 1216 facilitate the rapid removal of abrasive material used in the sandblasting process, preventing abrasive accumulation from negatively impacting the process. During sandblasting, the limiting strip 1213, not covered by the solar panels, can be directly struck by the sand, especially when the spray gun 141 oscillates. Designing the limiting strip 1213 as a continuous, flat structure (without through holes) increases its durability. The conveyor belt 1212, being covered by the solar panels, has a lower risk of being directly struck by sand; therefore, it is designed with through holes 1217 to facilitate rapid abrasive removal.

[0056] In one embodiment, the limiting component 122 includes a linkage rod 1225 and a plurality of limiting rollers 1220. The linkage rod 1225 extends along a first direction X, and the plurality of limiting rollers 1220 extend approximately along a second direction Y. The plurality of limiting rollers 1220 are spaced apart along the first direction X to provide uniform support for the conveyor belt 1212 and the limiting belt 1213. The plurality of limiting rollers 1220 includes a first limiting rod 1221, a second limiting rod 1222, a third limiting rod 1223, and a fourth limiting rod 1224. The first limiting rod 1221 and the pressure rod 133 are located on the same side of the conveyor belt 1212, and the plurality of second limiting rods 1222 are located on the other side of the single-layer conveyor belt 1212 relative to the pressure rod 133. The plurality of second limiting rods 1222 are connected by the linkage rod 1225, and the linkage rod 1225 is further connected to the first limiting rod 1221. The third limiting rod 1223 is disposed within the annular structure formed by the conveyor belt 1212 or the limiting belt 1213, and is close to and provides support and limitation for the conveyor belt 1212 and the limiting belt 1213, which are located above each other in the direction of gravity. The fourth limiting rod 1224 is disposed outside the annular structure formed by the conveyor belt 1212 or the limiting belt 1213, and is located below the conveyor belt 1212 and the limiting belt 1213 in the direction of gravity.

[0057] Understandably, the first limiting rod 1221 and the second limiting rod 1222 are set on both sides of the conveyor belt 1212 used to carry the solar panels, especially corresponding to the area where sandblasting is performed, to limit the conveyor belt 1212 and the limiting belt 1213 in this area, maintain the stability of the conveyor belt 1212 and the limiting belt 1213, and improve the stability of sandblasting and transporting the solar panels.

[0058] In this embodiment, the limiting roller 1220 extends along the second direction Y and has a thickened area 1226 and a normal area 1227 spaced apart in sequence. The thickened area 1226 is provided corresponding to the conveyor belt 1212, and the normal area 1227 is provided corresponding to the limiting belt 1213.

[0059] Understandably, the thickened area 1226 of the limiting roller 1220 corresponds to the conveyor belt 1212 and the ordinary area 1227 corresponds to the limiting belt 1213. The thickness of the thickened area 1226 is greater than the thickness of the ordinary area 1227 in order to achieve uniform support for the conveyor belt 1212 and the limiting belt 1213, and to minimize the possibility of the conveyor belt 1212 and the limiting belt 1213 sagging or shifting.

[0060] Further integration Figures 4 to 7As shown, in one embodiment, the tensioning assembly 123 includes two tensioning fixing rods 1231, which are spaced apart along a first direction X. Both tensioning fixing rods 1231 extend along a second direction Y and are located below the conveyor belt 1212 and the limiting belt 1213 along the direction of gravity. A portion of the tensioning components 1232 is connected to one tensioning fixing rod 1231. This portion of the tensioning components 1232 is spaced apart along the second direction Y and is used to abut against the conveyor belt 1212 to achieve tension. Another portion of the tensioning components 1232 is connected to the other tensioning fixing rod 1231. This portion of the tensioning components 1232 is spaced apart along the second direction Y and is used to abut against the limiting belt 1213 to achieve tension.

[0061] In one embodiment, the tensioning component 1232 includes a tensioning connecting frame 1233, a tensioning pushing part 1234, and an elastic member 1235. The tensioning connecting frame 1233 is configured to be fixedly disposed and located on one side of the conveyor belt 1212 or the limiting belt 1213. The tensioning pushing part 1234 is slidably connected to the tensioning connecting frame 1233. The elastic member 1235 is disposed between the tensioning connecting frame 1233 and the tensioning pushing part 1234 and is used to drive the tensioning pushing part 1234 to squeeze the conveyor belt 1212 or the limiting belt 1213 to achieve tension.

[0062] In this embodiment, the tensioning connecting frame 1233 is fixedly connected to the tensioning fixing rod 1231 by bolts, and the tensioning connecting frame 1233 is generally hollow frame-shaped. The tensioning pushing part 1234 includes a supporting part 1236 with rollers 1238 and a generally rod-shaped connecting part 1237. The connecting part 1237 passes through the tensioning connecting frame 1233 and is movably connected to the tensioning connecting frame 1233. The supporting part 1236 is located outside the tensioning connecting frame 1233 and is in abutting engagement with the conveyor belt 1212 or the limiting belt 1213 through the rollers 1238, so as to tension the conveyor belt 1212 or the limiting belt 1213 while ensuring that the conveyor belt 1212 or the limiting belt 1213 can continuously drive. The elastic element 1235 is sleeved on the outside of the connecting portion 1237. When the elastic element 1235 is in a compressed or stretched state, it can apply a force to the tensioning push portion 1234 to make it press against the conveyor belt 1212 or the limiting belt 1213.

[0063] In this embodiment, the structures of the tensioning pusher 1234 of the tensioning member 1232 for tensioning the conveyor belt 1212 and the tensioning pusher 1234 of the tensioning member 1232 for tensioning the limiting belt 1213 may differ. The side plate of the tensioning pusher 1234 for tensioning the conveyor belt 1212, which is used to fix the roller 1238, does not have a protrusion; however, the side plate of the tensioning pusher 1234 for tensioning the limiting belt 1213, which is used to fix the roller 1238, protrudes upwards along the tensioning direction, thus limiting the two sides of the limiting belt 1213.

[0064] Understandably, several tensioning components 1232 tension the conveyor belt 1212 and the limiting belt 1213 respectively, and the tensioning process can be continuously and adaptively adjusted by the elastic element 1235. This continuously maintains the tension of the conveyor belt 1212 and the limiting belt 1213, maintains the accuracy of the conveyor belt 1212 and the limiting belt 1213, extends the service life of the conveyor belt 1212 and the limiting belt 1213, and reduces the maintenance or replacement cycle.

[0065] Further integration Figure 3 As shown, in one embodiment, the thickness detection component 124 is located upstream of the sandblasting mechanism 14 along the first direction X. The thickness detection component 124 is suspended above the conveyor belt 1212 and is used to obtain the thickness parameters of the solar panels on the conveyor belt 1212.

[0066] In this embodiment, multiple detection brackets 1241 are respectively connected to the housing 11 and spaced apart along the second direction Y. Each detection bracket 1241 can be a sheet metal part. One section of each detection bracket 1241 extends along the first direction X and is used to support a detection sensor 1242. The detection sensor 1242 is connected to the detection bracket 1241 and suspended above the conveyor belt 1212, with its sensing end facing the conveyor belt 1212. The detection sensor 1242 can be a distance sensor used to detect the distance between its sensing end and the surface of the conveyor belt 1212. When no solar panels are placed on the surface of the conveyor belt 1212 or when a single solar panel is normally placed, the distance sensed by the detection sensor 1242 is basically within the normal range compared to the standard parameters, and therefore no fault is detected. However, when the solar panels on the surface of the conveyor belt 1212 are stacked, the distance parameter sensed by the detection sensor 1242 becomes significantly smaller and less than the normal value, triggering a warning from the data processing unit.

[0067] Understandably, if solar panels are stacked, some surfaces will inevitably show processing abnormalities during the sandblasting process. A thickness detection component 124 is installed upstream of the conveyor belt 1212 to detect the thickness parameters of the solar panels. When solar panels are stacked, at least two panels overlap along the thickness direction, resulting in a larger thickness parameter. By installing the thickness detection component 124, potential stacking can be detected promptly, facilitating timely intervention to eliminate potential problems and maintain the corresponding processing accuracy.

[0068] Further integration Figure 8 and Figure 9 As shown, in one embodiment, the pressure roller mechanism 13 includes a pressure roller drive assembly 131, a driven assembly 132, a plurality of pressure rods 133 and a plurality of couplings 134. The pressure roller drive assembly 131 and the driven assembly 132 are spaced apart along the second direction Y and located on opposite sides of the conveying mechanism 12 along the second direction Y.

[0069] In one embodiment, the pressure rod 133 is drivenly connected to the pressure roller drive assembly 131, and the pressure rod 133 is rotatably connected to the driven assembly 132. The pressure rod 133 is disposed between the pressure roller drive assembly 131 and the driven assembly 132 along the second direction Y, and each of the two ends of the pressure rod 133 spaced apart along the second direction Y is detachably connected to the pressure roller drive assembly 131 and the driven assembly 132 respectively through a coupling 134.

[0070] Understandably, the two ends of the pressure rod 133 are connected to the pressure roller drive assembly 131 and the driven assembly 132, respectively. The pressure roller drive assembly 131 is the active end that can output rotational torque, while the driven assembly 132 is the passive end that can maintain rotation. Fixing both ends makes the rotation process of the pressure rod 133 smoother. At the same time, each end of the pressure rod 133 is detachably connected to the pressure roller drive assembly 131 and the driven assembly 132 via a coupling 134. This allows for quick disassembly and assembly during equipment maintenance, reducing equipment maintenance time costs, increasing the effective usable time of the solar panel sandblasting equipment, and thus improving production efficiency.

[0071] In this embodiment, the pressure roller drive assembly 131 includes three output ends, and the driven assembly 132 includes three connection ends. There are three pressure rods 133, which are spaced apart along the first direction X.

[0072] In one embodiment, the pressure bar 133 includes a main bar 1331 and a plurality of thickened rings 1332 arranged around the outside of the main bar 1331 at intervals. The thickened rings 1332 are arranged corresponding to the conveyor belt 1212 and are at least partially located between the conveyor belt 1212 and the limiting belt 1213 along the second direction Y.

[0073] In this embodiment, multiple thickened rings 1332 are spaced apart along the second direction Y. Each thickened ring 1332 corresponds to a conveyor belt 1212. The thickened portion of the thickened ring 1332, which is thicker than the main rod 1331, extends into the space formed by the conveyor belt 1212 and the limiting belt 1213 for accommodating the battery panel, and is used to press the battery panel located on the surface of the conveyor belt 1212 tightly to prevent the battery panel from being blown away by the spray gun 141.

[0074] Understandably, the area of ​​the pressure bar 133 with the thickened ring 1332 is close to the sandblasting point area of ​​the spray gun 141. By setting the thickened ring 1332, the overall durability of the pressure bar 133 can be improved, the maintenance cycle can be reduced, and the overall processing efficiency can be improved.

[0075] In one embodiment, the pressure roller drive assembly 131 includes a pressure roller drive component 1311, a drive rod 1312, a sealing plate 1313, a bushing 1314, and at least two sealing rings 1315. At least a portion of the drive rod 1312 is located within the sandblasting processing space 111 and is connected to the pressure rod 133 via a coupling 134. The sealing plate 1313 and the at least two sealing rings 1315 are both located within the sandblasting processing space 111. An annular groove 1316 is formed on the outer periphery of the drive rod 1312. The sealing plate 1313 is sleeved on the outer periphery of the drive rod 1312 and engaged in the annular groove 1316. The at least two sealing rings 1315 are sequentially sleeved on the outer periphery of the drive rod 1312.

[0076] In this embodiment, the pressure roller drive component 1311 may include a drive motor, belt drive components, bearings, and other mechanisms. One drive motor drives multiple output ends through multiple belt drive components and multiple bearings. The multiple output ends are arranged at intervals approximately along the first direction X. The multiple belt drive components are linked to the multiple output ends and are used to drive and connect with multiple transmission rods 1312 respectively, thereby driving the multiple transmission rods 1312 to rotate and output rotational torque. A sealing plate 1313 is clamped on the outer periphery of the transmission rod 1312, and a bushing 1314 is further disposed on the sealing plate 1313. Two sealing rings 1315 are arranged side by side along the second direction Y on the transmission rod 1312 and located inside the bushing 1314 and fixed by the bushing 1314. The sealing plate 1313 and the two sealing rings 1315 cooperate to seal the boundary portion of the transmission rod 1312 extending into the sandblasting processing space 111.

[0077] Understandably, the sandblasting mechanism 14, located in the sandblasting processing space 111, is used to sandblast the solar panels. Due to the sandblasting process, a large amount of abrasive material exists within the sandblasting space 111. Some of this abrasive material may seep into the pressure roller drive assembly 131, causing damage to its related drive structure. By setting at least two sealing rings 1315, most of the abrasive material can be effectively isolated. Furthermore, to prevent further abrasive material seepage due to sealing ring 1315 failure or poor sealing, a sealing plate 1313 is fitted around the outer periphery of the transmission rod 1312. The sealing plate 1313 engages with the annular groove 1316 on the outer periphery of the transmission rod 1312. This fitted structure further prevents abrasive material from seeping into the pressure roller drive assembly 131. This double-layer protective structure reduces the probability of abrasive material seeping into the pressure roller drive assembly 131, thus reducing the probability of damage to the pressure roller drive assembly 131, minimizing downtime for maintenance of the solar panel sandblasting equipment, increasing the effective usable time of the solar panel sandblasting equipment, and ultimately improving production efficiency.

[0078] In one embodiment, the pressure roller drive assembly 131 has a pressurized cavity 1317, a sealing plate 1313 is disposed at the junction of the sandblasting processing space 111 and the pressurized cavity 1317, and a transmission rod 1312 passes through the pressurized cavity 1317 and extends into the sandblasting processing space 111; the pressure roller drive assembly 131 also has a pressurized hole 1318, which communicates with the pressurized cavity 1317 and is used to apply a positive pressure to the pressurized cavity 1317 that is greater than the air pressure in the sandblasting processing space 111.

[0079] In this embodiment, the pressure port 1318 is used to connect to an external pressure device or component (not shown). The pressure device or component applies pressure to the pressure cavity 1317 through the pressure port 1318, making the air pressure in the pressure cavity 1317 greater than or slightly greater than the air pressure in the sandblasting processing space 111. The positive or slightly positive pressure in the pressure cavity 1317 can prevent abrasive material from entering the pressure roller drive assembly 131 through the gaps on the outer surface of the drive rod 1312. This is especially effective when the sealing effect of the sealing ring 1315 and the sealing plate 1313 on the drive rod 1312 is weakened, further preventing abrasive material from entering the pressure roller drive assembly 131.

[0080] Understandably, the pressurized cavity 1317 is separated from the sandblasting processing space 111 by the sealing plate 1313. Theoretically, the sealing structure composed of the sealing plate 1313 and at least two sealing rings 1315 can prevent sand from entering the drive structure of the pressure roller mechanism 13. However, in actual use, it is difficult to maintain the sealing effect of the sealing plate 1313 and the sealing rings 1315 at a consistently high level. By adding a pressurized cavity 1317 at the rear end of the sealing structure formed by the sealing plate 1313 and the sealing rings 1315, and applying a positive pressure (specifically a slight positive pressure) greater than the air pressure inside the sandblasting processing space 111 through the pressurized hole 1318 connected to it, the pressure difference can further prevent sand from entering the drive structure of the pressure roller mechanism 13, further reducing the probability of damage to the pressure roller mechanism 13, reducing the number of downtime maintenance operations for the solar panel sandblasting equipment, increasing the effective usable time of the solar panel sandblasting equipment, and thus improving production efficiency.

[0081] Further integration Figure 2 and Figure 3 As shown, in one embodiment, the sandblasting mechanism 14 further includes a sandblasting bracket 142, a quick-release connecting rod 143, and a swing rod 144. The quick-release connecting rod 143 is detachably connected to the swing rod 144. Each side of the sandblasting bracket 142 is detachably connected to a quick-release connecting rod 143. The sandblasting bracket 142 has two spaced mounting holes 145 along the first direction X. The spray gun 141 is fitted into the mounting holes 145 and is inclined relative to the first direction X.

[0082] In this embodiment, the sandblasting bracket 142 has a generally symmetrical plate-like structure. Two mounting holes 145 are located on opposite sides of the sandblasting bracket 142 along the first direction X. The two spray guns 141 installed in the two mounting holes 145 are inclined downwards relative to the first direction X, so that the sand outlets of the two spray guns 141 are aligned with the opposite sides of the same pressure rod 133 along the first direction X (i.e., the two areas between the three pressure rods 133). The end of the quick-release connecting rod 143 connected to the sandblasting bracket 142 has a sleeve 1421. The sleeve 1421 is provided with multiple insertion holes 1422 for the insertion of pins. The multiple insertion holes 1422 are arranged at intervals along the direction of gravity. By adjusting the insertion hole 1422 into which the pin is inserted, the height of the sandblasting bracket 142 can be quickly adjusted. The end of the quick-release connecting rod 143 connected to the swing rod 144 is designed with a quick-release structure 1431 fixed by bolts or rivets, which can realize the quick-release connecting rod 143 and the swing rod 144. The swing arm 144 extends approximately along the first direction X. The swing arm 144 can be connected to a swing drive component located outside the housing 11. The swing drive component can drive the swing arm 144 to rotate or swing, thereby driving the sandblasting bracket 142 to swing via the quick-release link 143. The sandblasting bracket 142 can further drive the spray gun 141 to swing, so that the spray gun 141 can achieve uniform processing of the battery panel through swinging.

[0083] Understandably, the spray gun 141 is tilted within the mounting hole 145 via the sandblasting bracket 142, facilitating pre-adjustment and determination of the sandblasting impact area, thus ensuring sandblasting precision. Both sides of the sandblasting bracket 142 are connected to quick-release connecting rods 143, providing better stability during swinging. The detachable connection between the sandblasting bracket 142 and the quick-release connecting rods 143 facilitates height adjustment, and the detachable connection between the quick-release connecting rods 143 and the swing rod 144 enables rapid installation and disassembly, reducing installation and disassembly time, lowering equipment maintenance costs, increasing the effective usable time of the solar panel sandblasting equipment, and ultimately improving production efficiency.

[0084] Further integration Figure 1 As shown, in one embodiment, the sand recovery mechanism 15 includes at least a cyclone tailings recovery component 151 and a collection component 152. The collection component 152 is used to enrich the recovered sand, and the cyclone tailings recovery component 151 is used to guide or conduct the recovered sand into the collection component 152. The cyclone tailings recovery component 151 and the collection component 152 are connected by a relay pipe (not shown), which can be a flexible hose. The end of the cyclone tailings recovery component 151 connected to the relay pipe is provided with a first valve 1511, and the end of the collection component 152 connected to the relay pipe is provided with a second valve 1522. During the recovery process, the first valve 1511 can be opened first and the second valve 1522 can be closed first, allowing at least a portion of the sand in the cyclone tailings recovery component 151 to enter the relay pipe. Then, the first valve 1511 can be closed first and the second valve 1522 can be opened second, allowing at least a portion of the sand in the relay pipe to enter the collection component 152.

[0085] Understandably, if the cyclone tail material recovery component 151 and the collecting component 152 are directly connected, the sand at the end of the cyclone tail material recovery component 151 will impact the cyclone tail material recovery component 151 due to the influence of the return air, making the cyclone tail material recovery component 151 vulnerable to damage. By designing the first valve 1511 and the second valve 1522, the return air can be interrupted to a certain extent, avoiding excessive impact of sand on the cyclone tail material recovery component 151, improving the durability of the cyclone tail material recovery component 151, reducing the frequency of downtime maintenance of the solar panel sandblasting equipment, increasing the effective working time of the solar panel sandblasting equipment, and improving the production efficiency of the solar panel sandblasting equipment.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
