Description

Technical Field

[0001] The present invention relates to the technical field of solar cell production, and more particularly to an inclined overflow method and a cleaning device. Background Art

[0002] In the process of preparing photovoltaic cells of solar cells, the photovoltaic cells need to undergo surface treatment processes such as acid washing, alkali washing, water washing, and drying. When the photovoltaic cells are lifted out after being treated in the tank liquid, the surface of the photovoltaic cells tends to carry more water droplets, resulting in traces left on the surface of the photovoltaic cells after drying. Therefore, when cleaning the photovoltaic cells, they are generally lifted obliquely to avoid carrying more water droplets on the surface of the photovoltaic cells and improve production efficiency.

[0003] Most of the existing tilting and lifting methods are to set two driving motors at both ends respectively, and perform lifting and tilting operations through the action sequence of the driving motors. This structure is relatively complex, unstable in operation, and prone to poor synchronization. Summary of the invention

[0063] Figure 1 What is shown is a pre-drying structure in the patent with application number 201920066958.9, which is equipped with a cleaning device. According to the drawings and the description, in this scheme, two independent power sources are required at both ends of the movable bracket, through which the bracket is controlled to be in a horizontal state or an inclined state.

[0064] When performing cleaning work, this solution requires setting control programs for the two power sources to achieve different stages of process operations. This structure is independently driven at both ends, which occupies a large space.

[0065] Figure 2 Another existing slow-lifting device for flower baskets is shown, with publication number CN113345827A. The patent drives one of the first transmission assembly and the second transmission assembly to operate to achieve the tilt of the carrier and reduce the amount of water carried on the surface of the photovoltaic panel. This solution requires improvement of one of the transmission assemblies and changes in its transmission path, which may affect its stability.

[0066] In response to relevant problems in the prior art, this application explores and improves new solutions.

[0067] This embodiment provides a tilt overflow method, the device used includes a bracket 6, a lifting drive mechanism 3, and a tilt mechanism 2, and the bracket 6 in the cleaning tank 1 is used to place a flower basket 7, combined with Figures 3 to 5 The tilting mechanism 2 can drive the lifting driving mechanism 3 to move, so that the two ends of the bracket 6 move in opposite directions and tilt. The process includes the following:

[0068] The lifting drive mechanism 3 pulls the two ends of the bracket 6 through the first lifting belt 41 and the second lifting belt 42, so that the two ends of the bracket 6 can be lifted or lowered synchronously; the lifting drive mechanism 3 is installed on the substrate 22, and can drive the substrate 22 to slide relative to the cleaning tank 1 through the lifting driver 21, driving the lifting drive mechanism 3 to move, and the lifting drive mechanism 3 pulls the first lifting belt 41 and the second lifting belt 42 to move, so that the two ends of the bracket 6 move in the opposite direction and tilt, which can tilt and overflow.

[0069] According to different process requirements, in one embodiment, when the overflow is tilted, the lifting driver 21 drives the substrate 22 to slide relative to the cleaning tank 1, and the tight state of the first pulling belt 41 becomes a relaxed state; the second pulling belt 42 is further pulled to lift one end of the bracket 6, and the bracket 6 becomes tilted; then the lifting drive mechanism 3 is used to lift both ends of the bracket 6, so that the flower basket 7 is higher than the liquid surface, and the overflow is tilted.

[0070] In another way, when the overflow is tilted, the two ends of the bracket 6 are lifted by the lifting drive mechanism 3, and the flower basket 7 is higher than the liquid surface; then the lifting drive 21 drives the substrate 22 to slide relative to the cleaning tank 1, and the tight state of the first lifting belt 41 becomes a relaxed state; the second lifting belt 42 is further pulled to lift one end of the bracket 6, and the bracket 6 becomes tilted to overflow.

[0071] Based on the above methods, combined with Figure 3 , Figure 4, an inclined overflow cleaning device is provided, comprising a bracket 6, a lifting drive mechanism 3, and a tilting mechanism 2. The bracket 6 is arranged in a cleaning tank 1 for placing a flower basket 7. The lifting drive mechanism 3 comprises a motor 31 and a lifting roller shaft 32. The motor 31 adopts a servo motor, and its power output shaft is used to drive the lifting roller shaft 32 to rotate. One end of the first lifting belt 41 and the second lifting belt 42 are connected to the lifting roller shaft 32, and the other ends are respectively connected to the two ends of the bracket 6, so that the two ends of the bracket 6 can be lifted or lowered synchronously.

[0072] Preferably, a plurality of shaft seats 33 are provided on the lifting roller shaft 32 for mounting the lifting belt.

[0073] The tilting mechanism 2 includes a lifting drive 21 and a substrate 22. The substrate 22 is slidably arranged relative to the cleaning tank 1. The motor 31 and the lifting roller shaft 32 are both arranged on the substrate 22. The lifting drive 21 can drive the substrate 22 to slide. When the position of the substrate 22 changes, it can drive the first lifting belt 41 and the second lifting belt 42 to move, so that the two ends of the bracket 6 move in opposite directions and tilt.

[0074] Guide components are provided on the upper and lower sides of the cleaning tank 1, and the first lifting belt 41 and the second lifting belt 42 are both guided to change direction by the guide components; the roller in the guide component on the upper side of the cleaning tank 1 at least partially protrudes from the inner side surface of the cleaning tank 1, so that the first lifting belt 41, the second lifting belt 42 and the inner side surface of the cleaning tank 1 are in a non-contact state.

[0075] In the cleaning device, the cleaning tank 1 is a tank structure with an opening on the upper side to form a rectangular tank. The guide components are arranged at both ends of the length direction of the cleaning tank 1. In order to avoid the contact between the lifting belt and the inner side of the tank side wall and affect the movement stability, the roller in the guide component is required to at least partially protrude from the inner side of the cleaning tank 1. On the one hand, it can be lifted and lowered smoothly. On the other hand, there can be a certain reserved space at its lower end to obtain the possibility of tilting movement.

[0076] The cleaning tank 1 is a tank structure with an opening on the upper side. The tank can be an independent tank or can be equipped with rollers and other structures for movement. Since the focus of this embodiment is on the oblique pulling control during slow pulling, there is no specific restriction on the structure of the cleaning tank.

[0077] In another embodiment, there may be a lifting mechanism, which includes a lifting drive mechanism 3, a first lifting belt 41, and a second lifting belt 42; the lifting drive mechanism 3 leads the first lifting belt 41 to one side and connects it to one end of the bracket 6; the lifting drive mechanism 3 leads the second lifting belt 42 to the side away from the first lifting belt 41, and the second lifting belt 42 is connected to the other end of the bracket 6; the lifting drive mechanism 3 enables the two ends of the bracket 6 to be lifted or lowered synchronously. The first lifting belt 41 and the second lifting belt 42 can be provided in two groups, which can connect the four corners of the bracket 6 for a smoother rise. For some smaller brackets, a single group of lifting belts can also be used to assist in lifting with the bracket guide. The flower basket 7 can be placed on the bracket 6. Photovoltaic panels to be cleaned can be placed in the flower basket 7.

[0078] In one embodiment, the lifting drive mechanism 3 is a motor, and the output shaft of the motor transmits power so that the first lifting belt 41 and the second lifting belt 42 can be rolled up or unrolled, thereby driving the two ends of the bracket 6 to move synchronously. When rolling up, the two lifting belts are tightened and the bracket 6 rises; when unrolling, the bracket 6 falls. The tilting mechanism 2 includes a lifting drive 21 and a base plate 22. The lifting drive mechanism 3 is arranged on the base plate 22. The lifting drive 21 can drive the base plate 22 to slide relative to the cleaning tank 1. When the position of the base plate 22 changes, it can drive the first lifting belt 41 and the second lifting belt 42 to move, so that the two ends of the bracket 6 move in opposite directions and tilt.

[0079] The substrate 22 may be a flat plate structure, with the back side used to set the sliding member and the front side used to install the lifting drive mechanism. For easy installation, a seat plate may be arranged in a direction perpendicular to the plane of the substrate 22 to support the lifting drive mechanism 3.

[0080] The sliding direction of the substrate 22 is consistent with the movement direction of the lifting belt corresponding to the substrate 22 when it is rolled up or unrolled. Therefore, when the substrate moves, one lifting belt is loosened, and due to the gravity of the bracket 6, the corresponding end of the bracket 6 drops; the other lifting belt is tightened, and the corresponding end of the bracket 6 rises, thereby causing the bracket 6 to tilt rapidly.

[0081] Furthermore, in order to prevent the lifting belt from interfering with the cleaning tank 1 during movement, at least two rollers are included in the guide assembly located on the upper side of the cleaning tank 1, and the two rollers are arranged in parallel, and the distance between the distal ends of the two rollers is greater than the thickness of the side wall of the end face of the cleaning tank 1. On this basis, the first lifting belt 41 and the second lifting belt 42 can have a certain degree of freedom of tilt when connected to the lifting drive mechanism 3.

[0082] As a specific implementation, in order to achieve sliding of the substrate, the substrate 22 is directly slidably connected to the cleaning tank 1 .

[0083] Specifically, combined Figure 4A slideway 232 is provided on the back of the base plate 22, and a slide rail 231 is provided on the side of the cleaning tank 1. The slideway 232 cooperates with the slide rail 231, and the telescopic rod of the lifting driver 21 is connected to the base plate 22. The lifting driver 21 can be a cylinder, which is fixedly installed relative to the cleaning tank 1, and the end of the telescopic rod is connected to the base plate 22.

[0084] When the telescopic rod of the cylinder performs telescopic movement, the base plate 22 can slide up and down on the side of the cleaning tank 1. In addition, the slideway 232 and the slide rail 231 referred to in this embodiment are not limited to the structure in the figure. The slideway 232 and the slide rail 231 are mainly capable of realizing sliding connection, which can be a card slot match, or: a round hole or a square hole is set on the slideway 232 to match the slide rail 231, without specific restrictions.

[0085] In other embodiments, the lifting drive 21 may also be a hydraulic cylinder, or a linear motor, etc. It may be directly mounted on the cleaning tank 1, or may be mounted on a bracket of the cleaning tank 1. For stable driving, the lifting drive 21 corresponds to the middle area of ​​the substrate 22.

[0086] In another embodiment, the lifting drive mechanism 3 includes a motor 31 and a lifting roller shaft 32, and the output shaft of the motor 31 is used to drive the lifting roller shaft 32 to rotate; a plurality of shaft seats 33 are provided on the lifting roller shaft 32, and the ends of the first lifting belt 41 and the second lifting belt 42 are connected to the shaft seats 33.

[0087] Combination Figure 4 , Figure 5 The two ends of the lifting roller shaft 32 are mounted on the base plate of the substrate. The motor 31 can be a servo motor. The lifting roller shaft 32 is arranged parallel to the motor shaft. The lifting roller shaft 32 can be driven by a belt, a chain or a gear to rotate. The lifting roller shaft 32 can be a whole structure. Figure 5 In order to facilitate installation, the two shafts can be combined into one lifting roller shaft through a coupling.

[0088] Combination Figure 6 , Figure 7 The first lifting belt 41 and the second lifting belt 42 are both guided and changed in direction by the guide assembly. The base plate 22 is vertically arranged at one end of the cleaning tank 1, the first lifting belt 41 extends upward, changes direction and is connected to one end of the bracket 6; the second lifting belt 42 extends downward, changes direction through the guide assembly, folds around from the lower side of the cleaning tank 1, and is connected to the other end of the bracket 6.

[0089] Specifically, the guide assembly includes an upper guide assembly 51 located on the upper side of the cleaning tank 1, and a lower guide assembly 52 located on the lower side of the cleaning tank 1. Figure 6In the scheme, the first lifting belt 41 extends upward, bypasses the upper guide assembly 51, turns downward, and is connected to the end of the bracket 6. The second lifting belt 42 extends downward, bypasses the first lower guide assembly 52, turns to a horizontal direction, passes through the bottom of the cleaning tank 1, passes through the second lower guide assembly 52 and the upper guide assembly 51, and turns downward to connect to the other end of the bracket 6. A clamping block 66 is provided at the end of the bracket 6 for connecting the lifting belt.

[0090] For the guide assembly, in one embodiment, combined with Figure 7 Taking the guide assembly 51 as an example, it includes a support plate 510 fixed on the cleaning tank, and an adjustment plate 512 mounted on the support plate 510, and the roller is mounted on the adjustment plate 512. A first adjustment slot is opened on the support plate 510, and the adjustment plate 512 is fixed by a first adjustment bolt 511, so that the adjustment plate can be adjusted up and down.

[0091] Furthermore, a backing plate 513 is connected to the adjustment plate 512, and a second adjustment bolt 514 is vertically installed on the backing plate 513 to achieve more stable support. A connecting plate 515 can also be provided on the adjustment plate 512, the connecting plate is parallel to the side wall corresponding to the cleaning tank, and a second adjustment slot is opened on the connecting plate 515, and a third adjustment bolt 516 is installed to fix the adjustment plate 512 from the side.

[0092] As an embodiment, two sets of the first lifting belt 41 and the second lifting belt 42 are provided, and the two sets of lifting belts are symmetrically arranged about the cross section of the cleaning tank 1, and connected to the four corners of the bracket 6, so that the bracket 6 is in a suspended state. Since the lifting drive mechanism 3 drives the two sets of lifting belts synchronously, the stability is good, and no additional guide member of the bracket is required.

[0093] In order to further improve the stability, a limiter is provided on the cleaning tank 1 or the bracket 6 to control the bracket 6 to return to a horizontal state. The limiter can be a mechanical limiter, such as a corresponding blocking member, or a sensor.

[0094] Specifically, in one embodiment, a limit platform 101 is provided on the upper side of the cleaning tank 1, and the limit platform 101 protrudes from the inner edge of the side wall of the cleaning tank 1; a positioner 65 is provided on the bracket 6, and the positioner 65 is a positioning pin, which extends upward. Two limit platforms 101 are provided along the length direction of the cleaning tank 1, and there are two corresponding positioning pins on the bracket to limit the shaking of the bracket 6 and the flower basket 7 on the horizontal plane during the entire process of the bracket 6 being lifted up by the lifting belt, so as to stabilize the flower basket 7 during the lifting process.

[0095] In another embodiment, the lifting drive 21 is provided with a limiter, such as a limit sensor, for controlling the telescopic length of the telescopic rod of the lifting drive 21. Since the lifting belt moves synchronously when the lifting drive 21 drives the substrate to slide, the limit effect can also be achieved. Of course, this method can be combined with the positioning method of the limit table 101 and used simultaneously.

[0096] In combination with the above embodiments, the bracket 6 is used as a bearing member to bear the flower basket 7. In order to avoid moisture residue, the bracket 6 in this embodiment includes a plurality of support beams 61 arranged in parallel to form a frame structure with a hollow space.

[0097] Combination Figure 8 In order to locate the flower basket more quickly, a positioning rod 62 is mounted on the support beam 61; a longitudinal positioning block 64 is disposed on the positioning rod 62. The longitudinal positioning block 64 can prevent the flower basket 7 from moving along the length direction of the bracket.

[0098] Furthermore, the inner side surface of the longitudinal positioning block 64 is an inclined surface, that is, the side facing the flower basket is an inclined surface, which is used to guide the flower basket to be positioned.

[0099] As an optimization, a transverse positioning block 63 is also provided on the positioning rod 62, and the transverse positioning block 63 can cooperate with the slot at the bottom of the flower basket. The transverse positioning block 63 is a wedge-shaped structure, and the slot is stuck on the transverse positioning block 63, so as to avoid the transverse displacement of the flower basket.

[0100] The substrate can be provided at the side end of the cleaning tank, among other possible ways, such as Fig. 9 As shown, it can also be arranged at the bottom of the cleaning tank. In this case, the first lifting belt 41 and the second lifting belt 42 both need to be guided and redirected by the upper guide assembly 51 and the lower guide assembly 52.

[0101] Combined with the above implementation modes, Fig.10 The cleaning of the photovoltaic panels in the flower basket 7 includes the following processes:

[0102] Step 1: Place the flower basket 7 on the bracket 6 in the cleaning tank 1, place it in a low position, and clean the photovoltaic panels in the flower basket 7; as shown in 11, the flower basket is placed on the bracket in a horizontal state, and the flower basket 7 is initially in the lowest position.

[0103] Step 2: The flower basket 7 is lifted and tilted by the lifting drive mechanism 3 and the lifting drive 21, and tilted overflow is performed above the liquid surface.

[0104] The lifting drive 21 is turned on, pushing the base plate 22 upward, so that the lifting mechanism on the base plate 22 moves upward along the slide rail 231. At this time, the first lifting belt 41 moves upward, and the tight state becomes loose, and the bracket in the cleaning tank 1 moves downward due to the weight; the second lifting belt 42 is further pulled after the lifting mechanism moves upward, thereby lifting the other end of the bracket 6, and the bracket 6 becomes tilted, and the flower basket is tilted, such as Fig.12 Status shown.

[0105] Then the motor 31 rotates, driving the lifting belts on both sides to synchronously reel up and lift, and the flower basket bracket 6 rises in an inclined state. A sensor can be set to detect the height. After a certain height, the entire bracket 6 rises above the liquid level in the tank, and the water droplets on the surface of the photovoltaic panels in the flower basket overflow due to the inclined state of the flower basket. At the same time, during the oblique pulling process, the water on the internal rods of the flower basket will also flow to the end face of the flower basket, so that the moisture can be removed.

[0106] Step 3: After overflow, the lifting driver 21 is used to drive the substrate 22 back to its original position, and the bracket 6 returns to a horizontal state.

[0107] During this process, the lifting driver 21 is activated to retract the telescopic rod, and the bracket returns to a horizontal state. Fig.13 In the process of returning, in order to prevent horizontal position deviation, a positioning mechanism, such as a positioning pin, is provided on one side.

[0108] Step 4: The flower basket 7 is taken away and transferred to the next process.

[0109] The flower basket that has completed overflowing is sent to the next station, and the bracket remains stationary waiting for the flower basket from the previous station to be transferred to the bracket, and then the above process is repeated. In this process, the control of rising, falling and tilting is relatively simple, without the need for complex structures and cumbersome procedures, which improves process efficiency.

[0110] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
