Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, and more specifically to an automated transportation device for photovoltaic panels based on AGV. Background Technology

[0002] AGVs, or Automated Guided Vehicles, are transport vehicles capable of traveling along predetermined paths, possessing safety protection and various transfer functions. In industrial applications, they typically do not require a driver, being controlled by an onboard computer system to automate material handling. In current photovoltaic intelligent manufacturing plants, photovoltaic panels need to be transported from warehouses to production lines and transferred between processes. Manual handling or traditional forklift transport is time-consuming and labor-intensive, and the photovoltaic panels are easily damaged during transport. Therefore, using AGVs to transport photovoltaic panels has become the mainstream transportation method in today's photovoltaic intelligent manufacturing plants. However, existing AGV transport vehicles can only transport photovoltaic panels of a specified size, and the transport volume is small. To transport photovoltaic panels of other sizes, other AGV transport vehicles are required, increasing transportation costs. In addition, dust easily adheres to the surface of photovoltaic panels during the process flow of AGV transport vehicles, requiring cleaning of this dust during precision machining, increasing workload. To address these issues, we propose an AGV-based automated photovoltaic panel transport device. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automated photovoltaic panel transportation device based on AGV to solve the problems existing in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automated photovoltaic panel transportation device based on AGV, comprising a rack assembly, an airflow transmission assembly fixedly connected to the bottom of the rack assembly, the rack assembly comprising an adjustment platform, a main clamping assembly slidably sleeved on the inner side of the bottom of the adjustment platform, an auxiliary clamping assembly slidably sleeved on the inner side of the top of the adjustment platform, and a plurality of turbulence-disrupting components fixedly connected to the inner sides of both the main clamping assembly and the auxiliary clamping assembly;

[0005] The auxiliary clamping component is height-adjustable under the action of the adjustment platform and the main clamping component to adapt to photovoltaic panels of different lengths and specifications, and the photovoltaic panel is fixed by the turbulence component;

[0006] The airflow turbulence assembly includes a clamp plate with two movable tubes fixedly connected to one side. The clamp plate has an arc-shaped air passage inside, with one end of the arc-shaped air passage communicating with the movable tube and the other end located at the top of the clamp plate. One end of the movable tube is slidably sleeved in an air hole, so that the airflow generated by the airflow transmission assembly is ejected from the top of the clamp plate through the arc-shaped air passage to blow away dust on the surface of the photovoltaic panel and assist in fixing the photovoltaic panel.

[0007] Furthermore, the bottom of the airflow transmission component is fixedly connected to a transport vehicle component, the adjustment platform includes three base plates, the three base plates are horizontally stacked, and each of the three base plates is fixedly connected to a connecting plate at both ends.

[0008] Furthermore, the two supports on one side of the movable frame are rotatably connected to one end of the two connecting plates, and the two supports on the other side of the movable frame are slidably sleeved in the movable grooves at one end of the two connecting plates.

A cylinder is fixedly connected to the top of one horizontal side plate, and a telescopic rod is fixedly connected to the top of the other horizontal side plate. One side of the two vertical side plates is fixedly connected to one side of the slide rail.

[0010] Furthermore, a horizontal side plate is fixedly connected to the top of the cylinder and the telescopic rod 1. A vertical side plate is fixedly connected to one end of each horizontal side plate 2. A limiting plate 1 is fixedly connected to one side of each of the two vertical side plates 2. The bottom of the limiting plate 1 is provided with a plate groove, which corresponds to the plate groove of the lower fixed plate. A rack 1 is fixedly connected to the top of the limiting plate 1.

[0011] Furthermore, the auxiliary clamping assembly includes a limiting plate two, the top of the limiting plate two is provided with a plate groove, both sides of the limiting plate two are fixedly connected to vertical side plates three, one side of each of the two vertical side plates three is fixedly connected to a horizontal side plate three, the top of each of the two horizontal side plates three is fixedly connected to a telescopic rod two, the top of each of the two telescopic rod two is fixedly connected to a horizontal side plate four, one side of each of the two horizontal side plates four is fixedly connected to a vertical side plate four, and one side of each of the two vertical side plates four is fixedly connected to an upper fixing plate.

[0012] Furthermore, the upper fixing plate and the lower fixing plate have the same structure, the two sides of the upper fixing plate are fixedly connected to one side of the slide rail, and the bottom of the limiting plate is fixedly connected to the rack.

[0013] Furthermore, two springs are fixedly connected to one side of the clamping plate, and the springs are wrapped around the outside of the movable tube. The other side of the clamping plate is made of soft rubber, and one end of the spring is fixedly connected to the inner wall of the plate groove.

[0014] Furthermore, the airflow transmission assembly includes a rotating shaft, a fan blade fixedly sleeved on the top side of the rotating shaft, an air source housing fixedly connected to the top of the rotating shaft, and both the rotating shaft and the fan blade are located inside the air source housing. A vent is provided at the bottom of the side of the air source housing, an airflow duct is fixedly connected to the side of the air source housing, a plurality of short-range hoses are fixedly connected to the top of the airflow duct, a long-range hose is fixedly connected to the front of the airflow duct, a straight pipe is fixedly connected to one end of the long-range hose, a rectangular tube is fixedly connected to one end of the straight pipe, a plurality of connecting hoses are fixedly connected to the bottom of the rectangular tube, and the connecting hoses are fixedly connected to the air holes of the upper fixed plate.

[0015] Furthermore, the transport vehicle component includes an AGV transport vehicle, on the inner side of the top of the AGV transport vehicle is electrically connected to a wind turbine, the drive end of the wind turbine is fixedly connected to a rotating shaft, and the front of the AGV transport vehicle is provided with an operation control screen.

[0016] The technical effects and advantages of this invention are as follows:

[0017] The cylinder (1022) is used to raise the limiting plate (1023) and squeeze the middle bottom plate (1011), causing the movable frame (1013) to retract and increase its height to accommodate photovoltaic panels of different lengths. The photovoltaic panels are then vertically inserted into the slots of the lower fixed plate (1021) and the upper fixed plate (1032). The bottom or top of the photovoltaic panels is fixed by two clamps (1041) in each slot, so that the photovoltaic panels will not shake and collide with each other during transportation. This solves the problem that the existing AGV transport vehicles can only transport photovoltaic panels of a specified size and have a small transport volume. If other sizes of photovoltaic panels need to be transported, other AGV transport vehicles are required, which increases the transportation cost.

[0018] After the transport vehicle arrives at the designated location, the motor drives the gear to rotate, and the rack one (1024) and rack two (1033) meshing with the gear move in opposite directions respectively. The rack one (1024) and rack two (1033) drive the main clamping assembly (102) and the auxiliary clamping assembly (103) respectively, so that they are separated from the adjustment platform (101) and extend to both sides of the transport vehicle assembly (3), which facilitates the removal of the photovoltaic panel.

[0019] During transportation, the motor drives the fan blades to rotate at high speed, forming an airflow in the air source housing (202). The airflow is then dispersed into the short-range hose (204) through the airflow pipe (203). The airflow enters the lower fixed plate (1021) and the upper fixed plate (1032). The airflow in the lower fixed plate (1021) and the upper fixed plate (1032) is then fed into the clamping plate (1041) through the movable pipe (1042). Finally, the airflow is ejected from the end of the arc-shaped air passage. The end of the arc-shaped air passage is located on the side of the fixed end of the photovoltaic panel, which allows the airflow to blow away the dust near the photovoltaic panel. This prevents dust from adhering to the surface of the photovoltaic panel during the AGV transport vehicle's process flow and transportation, thus solving the problem of increasing the workload of cleaning this dust during precision machining.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The AGV-based photovoltaic panel automated transportation device involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Reference Figure 1 and Figure 2 The present invention provides an automated photovoltaic panel transportation device based on AGV, including a rack assembly 1, an airflow transmission assembly 2 fixedly connected to the bottom of the rack assembly 1, and a transport vehicle assembly 3 fixedly connected to the bottom of the airflow transmission assembly 2.

[0034] In this embodiment, it is necessary to further explain that the shelf component 1 solves the problem that the existing AGV transport vehicle can only transport photovoltaic panels of a specified size and the transport volume is small. If other sizes of photovoltaic panels need to be transported, other AGV transport vehicles are required, which increases the transportation cost. The airflow transmission component 2 avoids the adhesion of dust on the surface of photovoltaic panels during the process flow of the AGV transport vehicle, which solves the problem of cleaning this dust during precision processing and increasing the workload. The specific structure and working principle of the above components will be explained in detail later.

[0035] Reference Figure 3 The shelf assembly 1 includes an adjustment platform 101. A main clamping assembly 102 is slidably sleeved on the inner side of the bottom of the adjustment platform 101, and an auxiliary clamping assembly 103 is slidably sleeved on the inner side of the top of the adjustment platform 101. Several flow-disrupting components 104 are fixedly connected to the inner sides of both the main clamping assembly 102 and the auxiliary clamping assembly 103.

[0036] In this embodiment, it is necessary to further explain that the shelf assembly 1, as the main load-bearing structure of the photovoltaic panel, adjusts the overall height by adjusting the platform 101, thereby changing the distance between the main clamping assembly 102 and the auxiliary clamping assembly 103 to adapt to photovoltaic panels of different lengths. The main clamping assembly 102 and the auxiliary clamping assembly 103 clamp and fix the photovoltaic panel from the bottom and top, respectively. The airflow deflector 104 provided on its inner side can provide flexible clamping force during transportation and use airflow to clean the surface of the photovoltaic panel, preventing dust adhesion. This achieves compatible fixing of photovoltaic panels of different sizes and surface protection during transportation.

[0037] Reference Figure 4 The adjustment platform 101 includes three base plates 1011, which are horizontally stacked. Each base plate 1011 has a connecting plate 1012 fixedly connected to both ends. One end of each connecting plate 1012 has a movable groove. Movable frames 1013 are installed at both ends of adjacent base plates 1011. Two supports of the movable frame 1013 on one side are rotatably connected to one end of each of the two connecting plates 1012, and two supports on the other side are slidably fitted into the movable grooves at one end of each of the two connecting plates 1012. Slide rails 1014 are fixedly connected to both ends of the top of the bottom base plate 1011 and to both ends of the bottom of the top base plate 1011. An installation groove is provided in the middle of the middle base plate 1011, and a stepper motor is fixedly fitted into the installation groove. A gear is fixedly connected to the drive end of the stepper motor.

[0038] In this embodiment, it is necessary to further explain that the adjustment platform 101 forms a scissor-type lifting structure through three horizontally stacked base plates 1011 and movable frames 1013. One end of the movable frame 1013 between adjacent base plates 1011 is rotatably connected, and the other end slides in the movable slot. When the stepper motor on the middle base plate 1011 drives the gear to rotate, the gear meshes with racks 1024 and 1033 on the main clamping assembly 102 and auxiliary clamping assembly 103, respectively. The slide rails 1014 are fixed to the top of the bottom base plate 1011 and the bottom of the top base plate 1011, respectively, to guide the horizontal sliding of the main clamping assembly 102 and auxiliary clamping assembly 103, ensuring that the clamping assembly maintains stable alignment accuracy during height adjustment, thereby enabling the photovoltaic panel to be smoothly inserted and fixed in the panel slot.

[0039] Reference Figure 5The main clamping assembly 102 includes a lower fixing plate 1021. The top of the lower fixing plate 1021 is provided with several plate grooves. Several short-range hoses 204 are fixedly connected to the front of the lower fixing plate 1021. Two air holes are provided on the inner side of each plate groove, and the short-range hoses 204 are connected to the air holes. Vertical side plates are fixedly connected to both sides of the lower fixing plate 1021. Horizontal side plates are fixedly connected to both sides of the two vertical side plates. A cylinder 1022 is fixedly connected to the top of one horizontal side plate, and a telescopic rod is fixedly connected to the top of the other horizontal side plate. One side of the two vertical side plates is fixedly connected to one side of the slide rail 1014.

[0040] The cylinder 1022 and the top of the telescopic rod are fixedly connected to a horizontal side plate 2. One end of each horizontal side plate 2 is fixedly connected to a vertical side plate 2. One side of each vertical side plate 2 is fixedly connected to a limiting plate 1023. The bottom of the limiting plate 1023 is provided with a plate groove, which corresponds to the plate groove of the lower fixed plate 1021. The top of the limiting plate 1023 is fixedly connected to a rack 1024.

[0041] In this embodiment, it is necessary to further explain that the main clamping assembly 102 is used to fix the bottom of the photovoltaic panel. An adjustable clamping space is formed between its lower fixing plate 1021 and the limiting plate 1023. The lower fixing plate 1021 is fixed to the vertical side plate and slidably connected to the adjusting platform 101 via the slide rail 1014, ensuring stable horizontal movement. The limiting plate 1023 is raised and lowered vertically under the drive of the cylinder 1022 and the telescopic rod, thereby adjusting the distance between it and the lower fixing plate 1021 to accommodate photovoltaic panels of different thicknesses. This adjustment is also coordinated with the overall height adjustment of the adjusting platform 101. The bottom positioning of the photovoltaic panel is achieved by providing air holes on the inner side of the groove of the lower fixing plate 1021. The airflow provided by the airflow transmission component 2 is connected through the short-distance hose 204. The airflow enters the turbulence component 104 through the air holes to assist in clamping and cleaning the surface of the photovoltaic panel. The rack 1024 on the top of the limiting plate 1023 meshes with the gear driven by the stepper motor in the adjustment platform 101. When it is necessary to load or unload the photovoltaic panel, the gear drives the rack 1024 to move horizontally, so that the entire main clamping component 102 extends outward along the slide rail 1014, thereby providing sufficient operating space for picking up and placing the photovoltaic panel and realizing the automatic extension and retraction function of the clamping component.

[0042] Reference Figure 6The auxiliary clamping assembly 103 includes a second limiting plate 1031. The top of the second limiting plate 1031 is provided with a plate groove. Vertical side plates 3 are fixedly connected to both sides of the second limiting plate 1031. A horizontal side plate 3 is fixedly connected to one side of each of the two vertical side plates 3. Telescopic rods 2 are fixedly connected to the top of each of the two horizontal side plates 3. Horizontal side plates 4 are fixedly connected to the top of each of the two telescopic rods 2. Vertical side plates 4 are fixedly connected to one side of each of the two horizontal side plates 4. An upper fixing plate 1032 is fixedly connected to one side of each of the two vertical side plates 4. The upper fixing plate 1032 has the same structure as the lower fixing plate 1021. Both sides of the upper fixing plate 1032 are fixedly connected to one side of the slide rail 1014. A rack 2 1033 is fixedly connected to the bottom of the second limiting plate 1031.

[0043] In this embodiment, it is necessary to further explain that the auxiliary clamping component 103 is used to fix the top of the photovoltaic panel, corresponding vertically to the main clamping component 102, together forming a vertical clamping system for the photovoltaic panel. The upper fixing plate 1032 is fixedly connected to one side of the slide rail 1014 to maintain a relatively stable position. Its structure is the same as that of the lower fixing plate 1021, with internal grooves and air holes. It is connected to the airflow transmission component 2 via a connecting hose to supply air to the turbulence component 104 to achieve the top clamping and cleaning functions. The limiting plate 1031 is connected to the upper fixing plate 1032 via the telescopic rod 1032, and can be raised and lowered vertically under the drive of the telescopic rod 1032 to adjust the distance between it and the upper fixing plate 1032. To accommodate photovoltaic panels of varying thicknesses, the groove on the top of the limiting plate 1031 corresponds vertically to the groove on the upper fixing plate 1032, jointly clamping the top area of ​​the photovoltaic panel. The rack 1033 at the bottom of the limiting plate 1031 meshes with the gear driven by the stepper motor in the adjusting platform 101. When it is necessary to load or unload the photovoltaic panel, the gear drives the rack 1033 to move horizontally, causing the auxiliary clamping assembly 103 to extend outward along the slide rail 1014. The direction of movement of the rack 1033 is opposite to that of the rack 1024, enabling the main clamping assembly 102 and the auxiliary clamping assembly 103 to unfold to both sides simultaneously, providing bidirectional operating space for loading and unloading the photovoltaic panel and further improving loading and unloading efficiency.

[0044] After the transport vehicle arrives at the designated location, the motor drives the gear to rotate, and the rack 1024 and rack 2 1033 meshing with the gear move in opposite directions. The rack 1024 and rack 2 1033 respectively drive the main clamping assembly 102 and the auxiliary clamping assembly 103 to disengage from the adjustment platform 101 and extend to both sides of the transport vehicle assembly 3, facilitating the unloading of the photovoltaic panel.

[0045] Reference Figure 7 and Figure 8The turbulence assembly 104 includes a clamping plate 1041. Two movable tubes 1042 are fixedly connected to one side of the clamping plate 1041. Two springs are fixedly connected to one side of the clamping plate 1041, and the springs are wrapped around the outside of the movable tubes 1042. The other side of the clamping plate 1041 is made of soft rubber. One end of the spring is fixedly connected to the inner wall of the plate groove. An arc-shaped air passage is provided inside the clamping plate 1041. One end of the arc-shaped air passage is connected to the movable tube 1042, and the other end of the arc-shaped air passage is located at the top of the clamping plate 1041. One end of the movable tube 1042 is slidably sleeved in the air hole.

[0046] In this embodiment, it is necessary to further explain that the turbulence component 104 has the dual functions of clamping and fixing as well as airflow cleaning. The soft rubber design on one side of the clamping plate 1041 is in direct contact with the photovoltaic panel, which can avoid scratches or stress concentration on the surface of the photovoltaic panel during clamping. At the same time, the soft rubber material has a certain elastic deformation capability, which can adapt to the slight size difference of the edge of the photovoltaic panel, and enhance the fit and stability of the clamping. The spring is sleeved on the outside of the movable tube 1042, with one end abutting against the inner wall of the plate groove and the other end abutting against the clamping plate 1041, providing continuous elastic thrust to the clamping plate 1041, so that the clamping plate 1041 maintains the pre-tight force on the photovoltaic panel in the static state, and plays a buffering and shock absorption role during transportation, preventing the photovoltaic panel from shaking or colliding due to vibration. The movable tube 1042 is slidably fitted into the air hole in the plate groove. It serves as both a guide structure for the clamping plate 1041, allowing the clamping plate 1041 to extend and retract under the action of the spring, and a channel for airflow. When the airflow transmission assembly 2 is working, the airflow enters the internal air passage of the lower fixed plate 1021 or the upper fixed plate 1032 through the short-distance hose 204, enters the movable tube 1042 through the air hole, and is then transported through the movable tube 1042 to the arc-shaped air passage inside the clamping plate 1041. Finally, it is ejected from the end of the arc-shaped air passage located at the top of the clamping plate 1041. The arc-shaped air passage design allows the airflow to blow towards the surface of the photovoltaic panel at a certain angle, effectively dispersing the dust accumulated near the fixed end of the photovoltaic panel and preventing dust from adhering to the surface of the photovoltaic panel during transportation. At the same time, when the airflow flows in the movable tube 1042, it generates an outward thrust on the tube wall and a thrust from the airflow impacting the inner wall of the arc-shaped air passage. The combined force of the two thrusts is transmitted to the clamping plate 1041, further enhancing the clamping force of the clamping plate 1041 on the photovoltaic panel, achieving the effect of airflow-assisted clamping, and improving the overall stability of the photovoltaic panel during transportation.

[0047] The cylinder 1022 is used to raise the limiting plate 1023 and press the middle base plate 1011, causing the movable frame 1013 to retract and increase its height to accommodate photovoltaic panels of different lengths. The photovoltaic panels are then vertically inserted into the slots of the lower fixed plate 1021 and the upper fixed plate 1032. The bottom or top of the photovoltaic panel is fixed by two clamps 1041 in each slot, so that the photovoltaic panels will not shake and collide with each other during transportation. This solves the problem that existing AGV transport vehicles can only transport photovoltaic panels of a specified size and have a small transport volume. If other sizes of photovoltaic panels need to be transported, other AGV transport vehicles are required, which increases the transportation cost.

[0048] Reference Figure 9 and Figure 10 The airflow transmission component 2 includes a rotating shaft 201, with fan blades fixedly sleeved on the top side of the rotating shaft 201. An air source housing 202 is fixedly connected to the top of the rotating shaft 201, and both the rotating shaft 201 and the fan blades are located inside the air source housing 202. A vent is provided at the bottom of the side of the air source housing 202. An airflow duct 203 is fixedly connected to the side of the air source housing 202. Several short-range hoses 204 are fixedly connected to the top of the airflow duct 203. A long-range hose is fixedly connected to the front of the airflow duct 203. A straight pipe is fixedly connected to one end of the long-range hose. A rectangular tube is fixedly connected to one end of the straight pipe. Several connecting hoses are fixedly connected to the bottom of the rectangular tube. The connecting hoses are fixedly connected to the air holes of the upper fixed plate 1032.

[0049] In this embodiment, it should be specifically noted that the rectangular tube and the airflow duct 203 have the same structure, and the connecting hose and the short-distance hose 204 have the same structure.

[0050] The airflow transmission component 2 provides a stable and controllable airflow source for the entire device, while meeting the air path requirements of the main clamping component 102 and the auxiliary clamping component 103. The rotating shaft 201 drives the fan blades to rotate at high speed under the drive of the wind turbine 302, generating compressed airflow inside the air source housing 202. The ventilation port on the side of the air source housing 202 serves as the air inlet to ensure continuous airflow replenishment. The airflow pipe 1 203 divides the airflow generated by the air source housing 202 into two paths: one path delivers the airflow to the air holes of the lower fixed plate 1021 through several short-distance hoses 204 connected at the top, supplying air to the turbulence component 104 in the main clamping component 102; the other path delivers the airflow to the air holes of the upper fixed plate 1032 through the long-distance hose connected at the front, sequentially through a straight pipe, a rectangular tube, and several connecting hoses, supplying air to the turbulence component 104 in the auxiliary clamping component 103. The rectangular tube serves to distribute airflow evenly, ensuring that the air pressure and flow rate at the outlets of multiple connecting hoses remain consistent, so that each turbulence component 104 receives a balanced air supply. Through the above air path design, the airflow transmission component 2 can simultaneously provide cleaning air and auxiliary clamping air to the upper and lower clamping components, thereby achieving effective blowing of dust on the surface of the photovoltaic panel and dynamic enhancement of clamping force during transportation.

[0051] During transportation, the motor drives the fan blades to rotate at high speed, forming an airflow in the air source housing 202. The airflow is then dispersed into the short-range hose 204 through the airflow pipe 203. The airflow enters the lower fixed plate 1021 and the upper fixed plate 1032. The airflow in the lower fixed plate 1021 and the upper fixed plate 1032 is then fed into the clamping plate 1041 through the movable pipe 1042. Finally, the airflow is ejected from the end of the arc-shaped air channel, which is located on the side of the fixed end of the photovoltaic panel. This allows the airflow to disperse the dust near the photovoltaic panel, preventing dust from adhering to the surface of the photovoltaic panel during the AGV transport process. This solves the problem of cleaning this dust during precision machining, which increases the workload.

[0052] When the airflow from the lower fixed plate 1021 and the upper fixed plate 1032 enters the movable pipe 1042, the airflow simultaneously generates a thrust on the pipe wall of the movable pipe 1042, which in turn generates a thrust on the clamping plate 1041, further clamping the photovoltaic panel between the two clamping plates 1041 and improving the stability of the photovoltaic panel during transportation.

[0053] Reference Figure 11 The transport vehicle assembly 3 includes an AGV transport vehicle 301. A wind turbine 302 is electrically connected to the inner side of the top of the AGV transport vehicle 301. A rotating shaft 201 is fixedly connected to the drive end of the wind turbine 302. An operation control screen is provided on the front of the AGV transport vehicle 301.

[0054] In this embodiment, it is necessary to further explain that the transport vehicle component 3 serves as the mobile carrying platform and power core of the entire device, providing walking drive, air source power, and centralized control functions for the automated transportation of photovoltaic panels. The AGV transport vehicle 301 automatically travels along a preset guide path, realizing the transfer and transportation of photovoltaic panels between the warehouse and the production line, as well as between various processes. Its top provides a stable mounting base for the shelf component 1 and the airflow transmission component 2. The wind turbine 302 is fixedly installed on the inner side of the top of the AGV transport vehicle 301, and its drive end is directly connected to the rotating shaft 201, providing an independent power source for the airflow transmission component 2. This ensures that clean air and auxiliary clamping air are continuously generated during transportation, without relying on external air source equipment, thus improving the integration and flexibility of the device. The operation control screen serves as a human-machine interface, integrating functions such as path control of the AGV transport vehicle 301, start / stop and speed regulation of the wind turbine 302, extension and retraction control of the stepper motor in the rack assembly 1, and lifting control of the cylinder 1022. Operators can use the operation control screen to centrally manage the entire process of photovoltaic panel loading and unloading, size adaptation, transportation start-up, and airflow adjustment, thereby improving the intelligence level and ease of operation of the automated transportation device.

[0055] The working principle of this invention is as follows: The cylinder 1022 is used to raise the limiting plate 1023 and squeeze the middle bottom plate 1011, causing the movable frame 1013 to retract and increase its height to accommodate photovoltaic panels of different lengths. The photovoltaic panels are then vertically inserted into the slots of the lower fixed plate 1021 and the upper fixed plate 1032. The bottom or top of the photovoltaic panel is fixed by two clamping plates 1041 in each slot, so that the photovoltaic panels will not shake and collide with each other during transportation. This solves the problem that existing AGV transport vehicles can only transport photovoltaic panels of a specified size and have a small transport volume. If other sizes of photovoltaic panels need to be transported, other AGV transport vehicles are required, which increases the transportation cost.

[0056] During transportation, the motor drives the fan blades to rotate at high speed, forming an airflow in the air source housing 202. The airflow is then dispersed into the short-range hose 204 through the airflow pipe 203. The airflow enters the lower fixed plate 1021 and the upper fixed plate 1032, and is then fed into the clamping plate 1041 through the movable pipe 1042. Finally, the airflow is ejected from the end of the arc-shaped air channel, which is located on the side of the fixed end of the photovoltaic panel. This allows the airflow to disperse the dust near the photovoltaic panel, preventing dust from adhering to the surface of the photovoltaic panel during the AGV transport process. This solves the problem of cleaning this dust during precision machining, which increases the workload.

[0057] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
