Description

Technical Field

[0001] This invention relates to the field of photovoltaic production technology, and in particular to a photovoltaic robot. Background Technology

[0002] In silicon wafer processing, a carrier called a "cartridge" is used. After the silicon wafers are placed in the cartridge, they are transferred between different processing equipment using photovoltaic robots. A photovoltaic robot typically consists of a mobile chassis and a storage compartment mounted on the chassis. The storage compartment contains a conveying device. Generally, the mobile chassis moves to the processing equipment, and the conveying device docks with the equipment to load and unload the cartridge.

[0003] Because silicon wafers are thin, brittle, and extremely fragile, they are highly susceptible to breakage during basket transport and robot movement, causing fragments to fall into the conveying device and storage compartment. Furthermore, over long-term operation, dust accumulates on the storage compartment and conveying device, affecting the cleanliness of the silicon wafers; therefore, regular cleaning of the photovoltaic robot is necessary.

[0004] In addition, one end of the photovoltaic robot's conveying device needs to interface with the process equipment. Therefore, the drive mechanism of the conveying device is usually located at the end furthest from the interface, i.e., inside the storage compartment. During long-term operation, the conveying device requires regular or irregular maintenance.

[0005] In summary, photovoltaic robots require maintenance and cleaning. Because the storage compartment has a certain depth along the conveying direction of the transport device, it is inconvenient for operators to directly inspect and clean the interior from the docking end. Therefore, in existing technologies, to perform maintenance and cleaning on photovoltaic robots, it is usually necessary to remove the robot's back panel, inspect and clean the storage compartment and the transport device, and then reinstall the back panel. This method involves a complicated disassembly and assembly process, significantly impacting the efficiency of maintenance and cleaning. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention discloses a photovoltaic robot.

[0007] The technical solution adopted in this invention is as follows:

[0008] A photovoltaic robot, comprising:

[0009] The robot body includes a buffer device and a walking mechanism located at the bottom of the buffer device. The buffer device has openings on both sides, and the internal space of the buffer device is defined as the buffer space.

[0010] A conveying device is horizontally positioned within the buffer space of the buffer device, with both ends of the conveying device extending out of the buffer space from openings on both sides of the buffer device.

[0011] The maintenance window includes a maintenance window that is hinged to the buffer device at an opening on one side of the buffer device, and the maintenance window is recessed from the inside to the outside to form a recessed space.

[0012] In one embodiment of the present invention, a first locking unit disposed at the opening of the buffer device and a second locking unit disposed on the side of the inspection window are further included. The first locking unit and the second locking unit are adapted to each other and are used to lock the inspection window after it is closed.

[0013] In one embodiment of the present invention, the first locking unit includes a first locking bracket fixed to the opening of the buffer device and a locking pin disposed on the first locking bracket;

[0014] The second latching unit includes a second latching bracket fixedly installed on the side of the inspection window, a latching body fixed to the second latching bracket, and a first rotating member and a second rotating member rotatably connected to the latching body and rotatably resetting; the latching body has a first locking groove laterally opened on the side near the first latching unit; the first rotating member includes a locking tongue portion near one end of the second rotating member and a force-applying portion away from the other end of the second rotating member; the side of the second rotating member has a second locking groove and a locking groove respectively; the second latching unit is configured to include a first state and a second state;

[0015] When the second locking unit approaches the first locking unit, the locking pin abuts against the edge of the second locking groove and pushes the second rotating member to rotate until the locking tongue of the first rotating member is locked in the locking groove. At this time, the locking pin is locked in the locking space formed by the overlap of the first locking groove and the second locking groove, and the second locking unit is in the first state.

[0016] When the first rotating member applies an external force to disengage the locking tongue from the locking groove, the second rotating member resets and rotates, opening the locking space and pushing the locking pin away from the locking space, and the second locking unit is in the second state.

[0017] In one embodiment of the present invention, the second locking unit further includes a first rotating member and a second rotating member vertically mounted on the locking body, as well as a first torsion spring sleeved on the first rotating member and a second torsion spring sleeved on the second rotating member; the two ends of the first torsion spring respectively overlap the locking body and the first rotating member; the two ends of the second torsion spring respectively overlap the locking body and the second rotating member.

[0018] In one embodiment of the present invention, one side of the latch body is bent to form a first blocking portion for engaging the first torsion spring and a second blocking portion for engaging the second torsion spring. The second blocking portion is also configured to limit the second rotating member during rotational reset.

[0019] In one embodiment of the present invention, the groove edge of the first locking groove near the first rotating member extends obliquely from the groove opening of the first locking groove towards the side near the second rotating member, so that the groove edge of the first locking groove near the first rotating member forms a preset angle α with the moving plane direction of the second locking unit.

[0020] In one embodiment of the present invention, the direction perpendicular to the extension direction of the latch portion away from the side of the first rotating member points to the rotation center of the first rotating member.

[0021] In one embodiment of the present invention, the first locking bracket includes a first fixing part and a first supporting part, the first fixing part being fixedly connected to the buffer device; the locking pin is detachably installed on the first supporting part;

[0022] The second latch bracket includes a second fixing part fixedly connected to the inner wall of the inspection window and an mounting part fixedly connected to the second fixing part; the latch body is fixedly mounted on the side of the mounting part near the second fixing part; the mounting part has a first relief groove laterally opened on the side of the first latch bracket to avoid the latch pin; the second fixing part has a second relief groove to avoid the force-applying part;

[0023] The side of the inspection window has a through hole for operating the force-applying part.

[0024] In one embodiment of the present invention, an air purification device is also provided on top of the buffer device.

[0025] In one embodiment of the invention, a roller shutter door device is also provided at the opening on the side of the buffer device away from the inspection window.

[0026] The technical solution of the present invention has the following advantages compared with the prior art:

[0027] The photovoltaic robot described in this invention adopts a design where the conveying device extends to both sides of the frame of the buffer device. When the photovoltaic robot needs to be inspected and cleaned, it can be operated from both ends of the conveying device by opening the inspection window, which alleviates the inconvenience caused by the deep internal space of the buffer device.

[0028] Meanwhile, a buffer device extends from one end of the conveying device to facilitate docking with process equipment to convey flower baskets. This invention can reduce the tediousness of maintenance and cleaning and greatly improve the efficiency of maintenance and cleaning. Attached Figure Description

Detailed Implementation

[0043] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0044] The foregoing and other technical contents, features, and effects of the present invention will be clearly presented in the following detailed description of the embodiments with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as up, down, left, right, front, or back, are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the present invention. Furthermore, in all embodiments, the same reference numerals denote the same elements.

[0045] Currently, there is a need for maintenance and cleaning of photovoltaic robots. However, due to the considerable depth of the storage compartment along the conveying direction of the transport device, it is inconvenient for operators to directly perform maintenance and cleaning from the docking end. Therefore, in existing technologies, to perform maintenance and cleaning on photovoltaic flower basket robots, it is usually necessary to remove the rear panel of the photovoltaic flower basket robot, perform maintenance and cleaning on the storage compartment and the transport device, and then reinstall the rear panel after maintenance and cleaning. This method involves a complicated disassembly and assembly process, which greatly affects the efficiency of maintenance and cleaning.

[0046] Example 1

[0047] like Figure 1 As shown, in order to solve the above problems, this embodiment provides a photovoltaic robot.

[0048] Combination Figures 1-3 The photovoltaic robot provided in this embodiment includes a buffer device 100, a walking mechanism 600 located at the bottom of the buffer device 100, a conveying device 200 located inside the buffer device 100, and an inspection window 300 located on one side of the buffer device 100 along the length of the conveying device 200.

[0049] The buffer device 100 includes a frame 101, a housing 102 covering the frame 101, and a partition 103 disposed within the frame 101. The housing 102 is disposed along the width direction of the conveyor 200 on both sides and the top of the frame 101 and is fixedly connected to the frame 101. This creates a cavity structure with openings on both sides in the buffer device 100. The internal space of the buffer device 100 is defined as the buffer space. The conveyor 200 is disposed within the buffer space of the buffer device 100. The buffer space communicates with the outside along the length direction of the conveyor 200. The housing 102 is provided with at least one second observation window 306 made of transparent material, facilitating direct observation of the operation of the conveyor 200 inside the buffer device 100 or the cleanliness of the interior of the buffer device 100.

[0050] In a further embodiment, the buffer device 100 further includes a partition 103 disposed within the buffer space. The partition 103 is mounted on a support structure fixedly connected to the frame 101 or directly fixedly connected to the frame 101. This divides the internal space of the buffer device 100 into multiple independent buffer spaces. In this embodiment, the partition 103 divides the internal space of the buffer device 100 into two independent buffer spaces, one above the other. Furthermore, two conveying devices 200 are arranged side-by-side in each independent buffer space.

[0051] The conveying device 200 is horizontally positioned within the buffer device 100 and fixed to the frame 101. The length direction of the conveying device 200 is aligned with the length direction of the buffer space, and both ends of the conveying device 200 extend out of the buffer space of the buffer device 100. This addresses the issue of the conveying device 200 connecting with external equipment for material transport. Furthermore, by reducing the length of the conveying device 200 within the buffer device 100, it facilitates maintenance and cleaning of both the conveying device 200 and the buffer device 100 from both ends. In this embodiment, the conveying device 200 uses a belt conveyor to transport the flower basket. This belt conveyor structure can also be equivalently replaced by other conveying devices, such as roller conveyors / roller conveyors. The specific structure of the conveying device 200 is irrelevant to the technical problem to be solved in this application and will not be described in detail here.

[0052] The walking mechanism 600 is installed at the bottom of the frame 101 and is used to drive the buffer device 100 to move in any direction. The walking mechanism 600 includes a drive wheel and a driven wheel. The drive wheel has a power input. Specifically, the drive wheel can be a reduction drive integrated wheel connected to a motor, and the driven wheel can be a caster wheel.

[0053] The inspection window 300 is hinged to the frame 101 via a connecting element 301, and the side of the inspection window 300 opposite to the buffer space has a recessed space 302. Specifically, the inspection window 300 is located at the opening of the buffer device 100 away from the end that interfaces with external equipment. The connecting element 301 can be a hinge or a latch and is hinged to the frame 101 of the buffer device 100. The recessed space 302 on one side of the inspection window 300 avoids interference with the conveyor 200 when the inspection window 300 is closed; on the other hand, it compensates for the reduction in buffer space caused by the conveyor 200 extending out of the buffer device 100, ensuring the capacity of the photovoltaic robot's operating basket. The inspection window 300 has an inwardly latched handle 303 on the side opposite to the connecting element 301, which facilitates opening the inspection window 300 without occupying the installation space of the photovoltaic robot.

[0054] Furthermore, the inspection window 300 is provided with at least one first observation window 305 made of transparent material, which, together with the second observation window 306 on the housing 102, serves to observe the internal condition of the buffer device 100 from different perspectives.

[0055] When the photovoltaic robot needs maintenance and cleaning, the maintenance window 300 allows operation from both ends of the conveyor 200, alleviating the inconvenience caused by the deep internal space of the buffer device 100. Simultaneously, the buffer device 100 extends from one end of the conveyor 200, facilitating connection with process equipment for transporting flower baskets; after opening the maintenance window 300, the buffer device 100 extends from the other end of the conveyor 200, facilitating maintenance and cleaning of the conveyor 200. This solution reduces the complexity of maintenance and cleaning, significantly improving efficiency.

[0056] like Figure 4 As shown, in a further embodiment, the photovoltaic robot also includes a first locking unit 400 and a second locking unit 500. The first locking unit 400 is located at the opening of the buffer device 100, and the second locking unit 500 is located on the side of the inspection window 300. The first locking unit 400 and the second locking unit 500 are adapted to each other. The first locking unit 400 and the second locking unit 500 lock the closed inspection window 300 to prevent it from opening without reason. On the one hand, this reduces dust accumulation; on the other hand, it improves the safety of transporting or buffering flower baskets.

[0057] In this embodiment, the first locking unit 400 includes a first locking bracket 401 fixedly installed on the side of the frame 101 and a locking pin 402 disposed on the first locking bracket 401.

[0058] The structure of the first locking bracket 401 is shown in the attached figure. Figure 5 The first locking bracket 401 includes a first fixing part 4011 and a first support part 4012. The first fixing part 4011 and the first support part 4012 are bent relative to each other. The first fixing part 4011 is fixedly connected to the buffer device 100. The locking pin 402 is detachably installed on the first support part 4012. Specifically, the locking pin 402 is provided on the first support part 4012, and one end of the locking pin 402 is threaded. The first support part 4012 has a corresponding threaded hole (not shown). The locking pin 402 is threadedly connected to the first support part 4012, thereby realizing the connection between the locking pin 402 and the first locking bracket 401. If the locking pin 402 is damaged or deformed, causing the first locking unit 400 and the second locking unit 500 to not fit securely, the locking pin 402 can be easily and quickly replaced.

[0059] Combination Figures 6-8 The second locking unit 500 includes a second locking bracket 501 fixedly installed on the side of the inspection window 300, a locking body 502 fixed to the second locking bracket 501, and a first rotating member 503 and a second rotating member 504 rotatably connected to the locking body 502 and rotatably reset.

[0060] The structure of the second locking bracket 501 is shown in the attached document. Figure 6 The second latch bracket 501 includes a second fixing part 5011 and a mounting part 5012. The second fixing part 5011 is fixedly connected to the inner wall of the inspection window 300. The mounting part 5012 is fixedly connected to the second fixing part 5011. The latch body 502 is fixedly mounted on the side of the mounting part 5012 near the second fixing part 5011. A space is left between the second fixing part 5011 and the mounting part 5012 to install the latch body 502, the first rotating member 503, and the second rotating member 504, etc.

[0061] The structure of the locking body 502, the first rotating member 503, and the second rotating member 504 is shown in the attached diagram. Figure 7 and Figure 8The first rotating member 503 and the second rotating member 504 are rotatably connected to the latch body 502; and both the first rotating member 503 and the second rotating member 504 can be rotated back to their original positions. The latch body 502 is fixedly mounted on the mounting portion 5012 of the second latch bracket 501, specifically on the side of the mounting portion 5012 facing the second fixing portion 5011. The top corner of one side of the latch body 502 is bent to form a first blocking portion 5022, and the bottom corner of the latch body 502 on the same side is bent to form a second blocking portion 5023. A first locking groove 5021 is laterally formed on the side of the latch body 502 near the first latch unit 400. The bending angles of the first blocking portion 5022 and the second blocking portion 5023 can be the same or different, and the bending angles are designed according to installation requirements.

[0062] In this embodiment, the second locking unit 500 further includes a first rotating component 506 and a second rotating component 507, as well as a first torsion spring 508 and a second torsion spring 509 sleeved on the first rotating component 506. The first rotating component 506 and the second rotating component 507 are vertically mounted on the side of the locking body 502 facing the second fixing part 5011. Vertical mounting here means that the axes of the first rotating component 506 and the second rotating component 507 are perpendicular to the side of the locking body 502 facing the second fixing part 5011. Preferably, to improve the support performance of the first rotating component 506 and the second rotating component 507 and ensure the locking effect, both the first rotating component 506 and the second rotating component 507 are fixedly connected to the locking body 502. Furthermore, the first rotating component 506 and the second rotating component 507 are arranged vertically. Specifically, in physical space, the second rotating component 507 is located above the first rotating component 506.

[0063] The first rotating member 503 is rotatably connected to the first rotating member 506. A V-shaped locking tongue 5031 is formed at the top of the first rotating member 503. The locking tongue 5031 is located near one end of the second rotating member 504. The bottom of the first rotating member 503 is bent to form a force-applying part 5032. The force-applying part 5032 is located away from the end of the second rotating member 504. A first torsion spring 508 is sleeved on the first rotating member 506, and both ends of the first torsion spring 508 respectively overlap the first blocking part 5022 and the first rotating member 503. The rotational reset of the first rotating member 503 can be achieved through the torsional deformation of the first torsion spring 508.

[0064] The second rotating member 504 is rotatably connected to the second rotating member 507. The second rotating member 504 has a V-shaped locking groove 5042 adapted to the locking tongue 5031, and a U-shaped second locking groove 5041. It is understood that in practical applications, as long as the shapes of the locking tongue 5031 and the locking groove 5042 are complementary, it is not limited to both being V-shaped. The second torsion spring 509 can be sleeved on the first rotating member 506, and its two ends respectively overlap the second blocking part 5023 and the second rotating member 504. The torsional deformation of the second torsion spring 509 enables the rotational reset of the second rotating member 504. In this embodiment, the first torsion spring 508 and the second torsion spring 509 can also be equivalently replaced by elastic components with a rotational reset function, such as a spring.

[0065] The closing and opening process of the inspection window 300 will be explained below with reference to the attached diagram:

[0066] Combination Figure 9 and Figure 10 During the closing of the inspection window 300, the second locking unit 500 approaches the first locking unit 400. The locking pin 402 abuts against the edge of the second locking groove 5041 and pushes the second rotating member 504 counterclockwise until the locking tongue 5031 of the first rotating member 503 is locked in the locking groove 5042. At this time, the locking pin 402 is locked in the locking space 505 formed by the overlap of the first locking groove 5021 and the second locking groove 5041. At this time, the inspection window 300 is locked. The second locking unit 500 is defined as being in the first state at this time, that is, the second locking unit 500 is in the locked state.

[0067] Combination Figures 9 to 11 When the access window 300 needs to be opened, an external force is applied to the force-applying part 5032 of the first rotating member 503, causing the first rotating member 503 to rotate clockwise, and the locking tongue part 5031 disengages from the locking groove 5042. Under the action of the second torsion spring 509, the second rotating member 504 returns to its original rotation, opening the locking space 505 and pushing the latch pin 402 away from the locking space 505. At this time, the access window 300 is unlocked and can be fully opened manually. The second latch unit 500 is defined as being in the second state at this time, that is, the second latch unit 500 is in the unlocked state. In addition, the second blocking part 5023 can limit the rotation angle of the second rotating member 504 after unlocking. When the second rotating member 504 is limited, the first rotating member 503 is also limited.

[0068] In a further embodiment, the groove edge of the first locking groove 5021 near the first rotating member 503 extends obliquely from the groove opening of the first locking groove 5021 towards the side near the second rotating member 504, thereby causing the groove edge of the first locking groove 5021 near the first rotating member 503 to form a preset angle α with the moving plane direction of the second locking unit 500. Figure 9 As shown, the bottom edge of the first locking groove 5021 forms a preset angle α with the horizontal direction of the second locking unit 500. When locking the locking pin 402, the bottom edge of the first locking groove 5021 applies an upward force to the locking pin 402, avoiding the problem of poor locking effect caused by the groove width of the first locking groove 5021 or the second locking groove 5041 being greater than the diameter of the locking pin 402, and preventing loosening.

[0069] In a further embodiment, the vertical direction of the extension direction of the latch 5031 away from the side of the first rotating member 506 points to the rotation center of the first rotating member 503. That is, the extension direction of the latch 5031 away from the side of the first rotating member 506 is consistent with the tangent direction of the circle at that point with the axis of rotation of the first rotating member 506 as the axis of rotation and the distance from that side to the first rotating member 506 as the radius. With this arrangement, when the second locking unit 500 is unlocked and the first rotating member 503 rotates in the opposite direction (clockwise), the latch 5031 can disengage from the locking groove 5042 without overcoming the rotational resistance of the second rotating member 504, thus reducing the unlocking resistance.

[0070] In this embodiment, the mounting portion 5012 of the second locking bracket 501 has a first recessed groove 5013 on its side relative to the first locking bracket 401 to avoid the locking pin 402. This arrangement can compress the size of the second locking unit 500 and reduce the space occupied by the second locking unit 500. The second fixing portion 5011 has a second recessed groove 5014 near its bottom to avoid the force-applying portion 5032. The structural design of the first locking unit 400 and the second locking unit 500 also facilitates the internal installation of the locking units. The locking units are the first locking unit 400 and the second locking unit 500. This is not only aesthetically pleasing but also avoids exposing the locking units, preventing them from being bumped or damaged, thereby protecting the locking units. Specifically, the side of the inspection window 300 is provided with a through hole 304, which is opposite to the force-applying part 5032 of the first rotating member 503. When it is necessary to open the inspection window 300, a force is applied to the force-applying part 5032, so that the first rotating member 503 can be rotated clockwise to open the second locking unit 500.

[0071] Example 2

[0072] This embodiment provides a photovoltaic robot. The structure of the photovoltaic robot is the same as the technical solution in Embodiment 1, and will not be described again here.

[0073] Specifically, in combination Figure 12 The photovoltaic robot provided in this embodiment also includes an air purification device 700 disposed on top of the buffer device 100. The air purification device 700 purifies the air and introduces it into the buffer device 100, thereby creating high pressure inside the buffer device 100, thus preventing external dust from entering the buffer device 100 and keeping the silicon wafers on the basket inside the buffer device 100 clean.

[0074] Example 3

[0075] This embodiment provides a photovoltaic robot. The structure of the photovoltaic robot is based on the technical solution of Embodiment 1 or Embodiment 2, and will not be described again here.

[0076] Specifically, in combination Figure 12 The photovoltaic robot provided in this embodiment also includes a roller shutter door device 800 located on the side of the buffer device 100 away from the inspection window 300. The roller shutter door device 800 consists of multiple articulated door panels connected together. Within a fixed track, the door rotates up and down around a roller at the top of the door. The lifting and lowering of the door and the rolling shutter are controlled by an electric device, which serves to separate the outside world from the interior of the buffer device 100.

[0077] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.
