Description

Technical Field

[0001] This invention relates to the field of photovoltaic EL testing technology, and in particular to a testing device and testing method for solar photovoltaic panel production. Background Technology

[0002] Electroluminescence (EL) testing of solar photovoltaic (PV) panels is a non-destructive testing technique used to assess the internal quality and defects of PV modules. It captures the weak light signals emitted by the PV module when it is powered on (electroluminescence phenomenon) to generate high-contrast images, thus visually displaying the distribution of defects inside the module.

[0003] Solar photovoltaic (PV) panels generate electricity from numerous matrix-type photovoltaic modules. Failure of these modules can affect the overall performance of the PV panel. Currently, direct current (DC) is supplied to the PV panels, causing the power modules within to produce a faint light. Infrared cameras can record this light, but they can only determine if there are defects and their approximate location. They cannot pinpoint the exact location of the defects (for example, precise location of defects is required when repairing or disassembling the panel to analyze the cause of the malfunction). Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a testing device and method for the production of solar photovoltaic panels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a testing device for solar photovoltaic panel production, comprising: two photovoltaic panel conveying units, each photovoltaic conveying unit comprising: a frame, the frame being installed on the ground as a structural framework, a conveying component being installed on the frame, the conveying component including a mounting base, the mounting base being detachably fixed to the frame, a conveyor belt being installed inside the mounting frame, a motor being installed inside the mounting frame, the motor cooperating with a belt roller to drive the conveyor belt transmission (i.e., the existing conveyor belt structure), wherein the photovoltaic panel is placed above the conveyor belt, and the photovoltaic panel is horizontally conveyed under the rotation of the conveyor belt; A guide component is located between two photovoltaic panel conveying sections. The transmission component in the guide component can spray marking powder downwards. The marking powder is thinly coated on the surface of the photovoltaic panel (the marking powder is laser powder, and the laser powder changes color when irradiated by a high-energy laser, which is a conventional technology. Therefore, the laser powder ratio will not be described in detail here). A detection component is placed on one of the photovoltaic panel conveying sections. The detection component includes: a square cover installed on the photovoltaic panel conveying section; an infrared camera located inside the square cover, wherein the photovoltaic panel is fed into the square cover by the photovoltaic panel conveying section, and the infrared camera captures images of the photovoltaic panel connected to a DC power supply; a laser matrix evenly distributed inside the square cover, wherein the laser matrix emits lasers towards the faulty part of the photovoltaic panel to activate marking powder to mark the photovoltaic panel; and light-shielding parts are provided at both ends of the square cover, wherein the light-shielding parts can be multiple opaque flexible fabrics, using the flexible fabrics for light shading.

[0006] The aforementioned components achieve the following effect: The solar photovoltaic panel to be tested is placed on a conveyor belt on a conveyor component (it can be placed manually or by a robotic arm). The conveyor belt is driven by a motor to transport the photovoltaic panel. When the photovoltaic panel is transported between two photovoltaic panel transport sections, a guide component evenly sprays marking powder downwards. The marking powder adheres to the photovoltaic panel. Then, the photovoltaic panel is transported again by a conveyor belt on another photovoltaic transport section. The photovoltaic panel is transported into a square cover (at which point the conveyor belt stops working). Then, DC power is connected to the solar photovoltaic panel (it can be manually connected). The square cover serves to cover the photovoltaic panel to shield it from external light and prevent it from affecting the monitoring. An infrared camera captures images of the photovoltaic panel with DC power applied. By importing the data captured by the infrared camera into a computer, the color spots (abnormal brightness locations) are analyzed, and a high-energy laser is generated at the corresponding position of the laser matrix to irradiate the surface of the photovoltaic panel (since computer color judgment is a conventional procedure, and the laser matrix consists of multiple high-energy laser probes evenly arranged, it will not be elaborated on here). This causes the laser powder on the surface to change color, melt, and adhere to the surface of the photovoltaic panel for marking. The marked position can accurately indicate the location of the fault.

[0007] Preferably, the guide member includes: A guide frame, which is detachably mounted on the photovoltaic panel conveying section, wherein the guide frame serves as a vertical support; The top frame is inclined, with one side of the top frame closer to the square cover being lower than the other side. Guide wheels are rotatably installed below the top frame, which can clamp the photovoltaic panel and restrict the direction of photovoltaic panel transportation. The diameter of the guide wheels gradually increases from the bottom to the top. This structure can clamp both sides of the photovoltaic panel and also abut against the top of the photovoltaic panel. The surface of the guide wheels is uniformly covered with annular silicone rings to increase the friction of the photovoltaic panel. The guide wheels are made of flexible material to avoid damaging the photovoltaic panel.

[0008] The effects achieved by the above components are as follows: the flexible guide wheels can clamp the photovoltaic panel, which can restrict the position of the photovoltaic transmission. The inclined top frame ensures that the guide wheels of the photovoltaic panels clamped on both sides of the photovoltaic panel are also inclined, so that the photovoltaic panel is also inclined. When the laser powder is applied to the inclined photovoltaic panel, the laser powder can slide freely and be applied relatively evenly, thereby avoiding the accumulation of laser powder.

[0009] Preferably, the transmission component includes: A core tube, the inside of which contains marking powder, wherein the surface of the core tube has a powder outlet; The cylindrical shell is fitted onto the surface of the core tube, and a material leakage groove is provided at the bottom of the cylindrical shell. The marking powder leaks out from the material leakage groove along the powder outlet to coat the surface of the photovoltaic panel. A core tube is inserted into and fixed to a core cylinder. Holes are provided on the surface of the core tube, and air is blown from the core tube into the core cylinder to spray out marking powder.

[0010] The effect achieved by the above components is as follows: an air pump can be connected to the core tube port, and the air pump blows air into the core tube. The side of the core tube is provided with an openable material door, through which laser powder is added into the core tube. The core tube blows air into the core tube, thereby increasing the air pressure in the core tube and causing the laser powder to be sprayed out from the powder outlet. The sprayed laser powder is sprinkled on the surface of the photovoltaic panel being transported.

[0011] Preferably, the upper end of the top frame is provided with a gear set, wherein the output end of the gear set drives the core cylinder to rotate through a pulley and belt. The gear set includes two meshing bevel gears, one of which is fixed by a round shaft and a guide wheel. The rotation of the guide wheel drives the bevel gear to rotate. The other bevel gear is equipped with a pulley. The inner wall of the belt is provided with anti-slip teeth. The surface of the core cylinder is provided with pulleys. The belt is sleeved on the surface of the two pulleys to transmit power. Both bevel gears are rotatably connected to the top frame. The upper end of the top frame is detachably installed with a cylinder seat. The cylinder seat and the core cylinder are rotatably connected. Both ends of the cylinder shell are fixed to the cylinder seat. The material leakage grooves are evenly opened on the surface of the core cylinder. The surface of the cylinder shell is provided with an upwardly curved lifting rod at a position relative to the material leakage groove. The free end of the lifting rod abuts against the surface of the core cylinder. The two ends of the core cylinder are sealed, and the core tube and the seal are rotatably assembled by means of a sealing bearing.

[0012] The effect achieved by the above components is as follows: when the photovoltaic panel is conveyed between the two sets of guide wheels, it drives the conveyor wheel to rotate. The rotation of the conveyor wheel drives the input end of the bevel gear set to rotate (i.e., one of the bevel gears rotates). Through the output end of the bevel gear set (i.e., the central shaft of the other bevel gear rotates), it drives the pulley. The pulley drives the pulley on the surface of the core cylinder to rotate through the belt, thereby making the core cylinder rotate. During the rotation of the core cylinder, the lifting rod continuously scrapes and scrapes to ensure the vibration of the core cylinder (reducing the probability of laser powder blockage), allowing the laser powder in the core cylinder to be continuously discharged from the powder outlet at the lower end.

[0013] Preferably, a lifting member is provided between the two photovoltaic panel conveying sections, the lifting member comprising: Two sets of telescopic rods that can be lifted upwards, each telescopic rod including a sliding rod, with a pressure rod slidably inserted into the upper end of the sliding rod, and a spring provided between the sliding rod and the pressure rod. A cylinder is installed on the ground, and an assembly plate is fixedly connected to the output end of the cylinder. The assembly plate is fixedly connected to the sliding rod, and a mounting plate is fixedly connected to the surface of the cylinder. The sliding rod and the mounting plate are slidably connected. A conveying component is provided, with its bottom and a set of telescopic rods rotatably connected by a rotating seat. The lower part of the conveying component and another set of telescopic rods are slidably connected by a rotating seat. A mounting base and a rotating seat of a set of telescopic rods are mounted on the mounting base. A track is mounted on the bottom of the mounting base, and the track and the rotating seat of the other set of telescopic rods slide together.

[0014] The effect achieved by the above components is as follows: when a photovoltaic panel is being transported from one photovoltaic panel conveyor to another (i.e., when the photovoltaic panel is between the two photovoltaic panel conveyors, the conveyor belts in the two photovoltaic panel conveyors stop), the cylinder pushes the assembly plate upward, the assembly plate drives the slide bar to move upward, and thus the conveying component carries the photovoltaic panel upward, allowing the photovoltaic panel to press against the inclined top frame, thereby causing the photovoltaic panel to tilt, that is, the telescopic rod on one side retracts (the photovoltaic panel can slide downward between the guide wheel and the conveyor belt under the action of gravity).

[0015] Preferably, the photovoltaic transmission section is provided with a buffer component, the buffer component comprising: The assembly frame is detachably mounted on the photovoltaic conveyor unit. The assembly frame includes a buffer frame that is detachably fixed to the frame, and a V-belt frame is installed on the buffer frame. A support frame, wherein the support frame mounts two rollers on a V-belt bracket; A compression member, wherein the compression member is detachably mounted on a V-belt frame; The buffer belt is sleeved on the pressure-bearing component and the two rollers to form a triangular structure. The triangular structure of the buffer belt can cause the pressure-bearing component to deform under force. An electric motor, wherein the motor is detachably mounted on an assembly frame, and the output end of the motor is connected to a chain and roller drive via a sprocket.

[0016] The effect achieved by the above components is as follows: the buffer belt blocks one side of the inclined photovoltaic panel. When the photovoltaic panel needs to be transported, the motor is started, the motor drives the roller to rotate, the roller drives the buffer belt to rotate, and the buffer belt squeezes the pressure component with the friction between it and the photovoltaic panel, so that the buffer belt deforms and tilts downward to transport the photovoltaic panel. The frame is equipped with a buffer part, which can be an inflatable ball. The inclined photovoltaic panel falls into the buffer part for cushioning to avoid the photovoltaic panel directly hitting the conveyor belt.

[0017] Preferably, the pressure-bearing component includes: a cylinder, the cylinder being fixed on an assembly frame, a round rod being slidably inserted into the cylinder, a cylinder frame being installed at the free end of the round rod, a pressure-bearing cylinder being rotatably installed in the cylinder frame, and a spring being fixedly installed between the cylinder and the round rod.

[0018] The effect achieved by the above components is that the buffer belt is an elastic ring belt, which shrinks and deforms when the round rod retracts into the cylinder.

[0019] A testing method for solar photovoltaic panel production, using the aforementioned testing device for solar photovoltaic panel production.

[0020] Compared with the prior art, the advantages and positive effects of the present invention are as follows: In this invention, an infrared camera captures images of a photovoltaic panel with direct current applied. The data captured by the infrared camera is imported into a computer, and the color spots (abnormal brightness locations) are analyzed. The corresponding positions of the laser matrix are then driven to generate high-energy lasers that irradiate the surface of the photovoltaic panel, causing the laser powder on the surface to change color, melt, and adhere to the surface of the photovoltaic panel for marking. The location of the markings can accurately indicate the location of the fault. Attached Figure Description

[0023] Example 1, as Figure 1 , Figure 2 and Figure 10As shown, a testing device for solar photovoltaic panel production includes: two photovoltaic panel conveying sections, each including: a frame 1, which is installed on the ground as a structural frame; a conveying component 2 installed on the frame 1; the conveying component 2 including a mounting base 21, which is detachably fixed to the frame 1; a conveyor belt 22 installed inside the mounting base; a motor installed inside the mounting base; the motor, in conjunction with a belt roller, drives the conveyor belt 22 (i.e., an existing conveyor belt structure); the photovoltaic panels are placed above the conveyor belt 22 and are horizontally conveyed under the rotation of the conveyor belt 22; and a guide component 4, located between the two photovoltaic panel conveying sections. A transmission component 45 in the guide component 4 can spray marking powder downwards, which is thinly coated on the surface of the photovoltaic panels. The marking powder is laser powder. Laser powder changes color when irradiated by a high-energy laser, which is a conventional technology, so the laser powder ratio will not be elaborated here. Detection component 7 is placed on one of the photovoltaic panel conveying parts. Detection component 7 includes: a square cover 71 installed on the photovoltaic panel conveying part; an infrared camera 73 located inside the square cover 71, wherein the photovoltaic panel is fed into the square cover 71 by the photovoltaic panel conveying part, and the infrared camera 73 photographs the photovoltaic panel connected to the DC power supply; a laser matrix 72 evenly distributed inside the square cover 71, wherein the laser matrix 72 emits lasers toward the faulty part of the photovoltaic panel to activate the marking powder to mark the photovoltaic panel; and light-shielding parts 74 are provided at both ends of the square cover 71, wherein the light-shielding parts 74 can be multiple opaque flexible fabrics, which are used to block light. The solar photovoltaic panel to be tested is placed on the conveyor belt 22 of the conveying component 2 (this can be done manually or by a robotic arm). The conveyor belt 22 is driven by a motor to transport the photovoltaic panel. When the photovoltaic panel is transported between two photovoltaic panel transport sections, the guide component 4 sprays marking powder downwards evenly. The marking powder adheres to the photovoltaic panel. Then, the photovoltaic panel is transported again using the conveyor belt 22 on another photovoltaic transport section. The photovoltaic panel is transported into the square cover 71 (at this time, the conveyor belt 22 stops working). Then, DC power is connected to the solar photovoltaic panel (this can be done manually). The square cover 71 serves to cover the photovoltaic panel to block light and prevent external light from affecting the monitoring. The infrared camera captures images of the photovoltaic panel with DC power. By importing the data captured by the infrared camera into the computer, the color spots (abnormal brightness locations) are analyzed, and the laser matrix 72 is driven to generate high-energy lasers at the corresponding positions to irradiate the surface of the photovoltaic panel (since computer color judgment is a conventional procedure, and the laser matrix 72 consists of multiple high-energy laser probes evenly arranged, it will not be described in detail here). This causes the laser powder on the surface to change color, melt, and adhere to the surface of the photovoltaic panel for marking. The location of the marking can accurately indicate the location of the fault.

[0024] like Figure 5-7As shown, the guiding component 4 includes: a guide frame 41, which is detachably mounted on the photovoltaic panel conveying section, serving as a vertical support; and a top frame 42, which is inclined, with one side of the top frame 42 closer to the square cover 71 being lower than the other side. A guide wheel 43 is rotatably mounted below the top frame 42, which clamps the photovoltaic panel and restricts its conveying direction. The diameter of the guide wheel 43 gradually increases from the bottom to the top. This structure can clamp both sides of the photovoltaic panel while also abutting the top of the panel. A uniformly fitted silicone ring is present on the surface of the guide wheel 43 to increase the friction of the photovoltaic panel. The guide wheel 43 is made of a flexible material to prevent damage to the photovoltaic panel. The flexible guide wheel 43 clamps the photovoltaic panel, restricting its conveying position. The inclined top frame 42 ensures that the guide wheels 43 clamping the photovoltaic panels on both sides are also inclined, causing the photovoltaic panel to be inclined as well. When applying laser powder to the inclined photovoltaic panel, the laser powder can slide freely and be applied relatively evenly, thus preventing laser powder accumulation.

[0025] like Figure 5-7 As shown, the transmission component 45 includes: a core cylinder 452, which contains marking powder and has a powder outlet on its surface; a cylinder shell 451, which is fitted onto the surface of the core cylinder 452 and has a material leakage groove at its bottom, through which the marking powder leaks out along the powder outlet to coat the photovoltaic panel surface; and a core tube 453, which is inserted into and fixed to the core cylinder 452 and has holes on its surface, through which the core tube 453 blows air into the core cylinder 452 to spray out the marking powder. An external air pump can be connected to the port of the core tube 453. The air pump blows air into the core tube 453. The side of the core cylinder 452 is provided with an openable material door. Laser powder is added into the core cylinder 452 through the material door. The core tube 453 blows air into the core cylinder 452, thereby increasing the air pressure in the core cylinder 452 and causing the laser powder to be sprayed out from the powder outlet. The sprayed laser powder is sprinkled on the surface of the photovoltaic panel being transported.

[0026] like Figure 5-7As shown, a gear set 44 is provided at the upper end of the top frame 42. The output end of the gear set 44 drives the core cylinder 452 to rotate through a pulley and belt. The gear set 44 includes two meshing bevel gears. One bevel gear is fixed by a round shaft and a guide wheel 43. The rotation of the guide wheel 43 drives the bevel gear to rotate. The other bevel gear is equipped with a pulley. The inner wall of the belt is provided with anti-slip teeth. The surface of the core cylinder 452 is provided with pulleys. The belt is wrapped around the surface of the two pulleys to transmit power. Both bevel gears are rotatably connected to the top frame 42. A cylinder seat 46 is detachably installed at the upper end of the top frame 42. The cylinder seat 46 is rotatably connected to the core cylinder 452. Both ends of the cylinder shell 451 are fixed to the cylinder seat 46. The material leakage grooves are evenly opened on the surface of the core cylinder 452. An upwardly curved lifting rod is provided on the surface of the cylinder shell 451 relative to the material leakage groove. The free end of the lifting rod abuts against the surface of the core cylinder 452. The two ends of the core cylinder 452 are sealed, and the core tube 453 and the seal are rotatably assembled by means of a sealing bearing. When the photovoltaic panel is conveyed between the two sets of guide wheels 43, it drives the conveyor wheel to rotate. The rotation of the conveyor wheel drives the input end of the bevel gear set 44 to rotate (i.e., one of the bevel gears rotates). The output end of the bevel gear set 44 (i.e., the central shaft of the other bevel gear rotates) drives the pulley. The pulley drives the pulley on the surface of the core cylinder 452 to rotate through the belt, thereby making the core cylinder 452 rotate. During the rotation of the core cylinder 452, the lifting rod continuously scrapes and scrapes to ensure that the core cylinder 452 vibrates (reducing the probability of laser powder blockage), so that the laser powder in the core cylinder 452 is continuously discharged from the powder outlet at the lower part.

[0027] like Figure 3-4As shown, a lifting component 3 is provided between the two photovoltaic panel conveying sections. The lifting component 3 includes two sets of telescopic rods that can be lifted upwards. Each telescopic rod includes a slide rod 33. A pressure rod 35 is slidably inserted into the upper end of the slide rod 33. A spring is provided between the slide rod 33 and the pressure rod 35. A cylinder 31 is installed on the ground. An assembly plate 34 is fixedly connected to the output end of the cylinder 31. The assembly plate 34 and the slide rod 33 are fixedly connected. An mounting plate 32 is fixedly connected to the surface of the cylinder 31. The slide rod 33 and the mounting plate 32 are slidably connected. A conveying component 2 is provided. The bottom of the conveying component 2 and a set of telescopic rods are rotatably connected by a rotating seat 37. The bottom of the conveying component 2 and another set of telescopic rods are slidably connected by a rotating seat 37. A mounting seat 21 is installed on the rotating seat 37 of the set of telescopic rods. A track 36 is installed on the bottom of the mounting seat 21. The track 36 and the rotating seat 37 of the other set of telescopic rods slide together. When a photovoltaic panel is being transported from one photovoltaic panel conveyor to another (i.e., when the photovoltaic panel is between the two photovoltaic panel conveyors, the conveyor belts 22 in both photovoltaic panel conveyors stop), the cylinder 31 pushes the assembly plate 34 upward. The assembly plate 34 drives the slide bar 33 to move upward, thereby causing the conveying component 2 to carry the photovoltaic panel upward, so that the photovoltaic panel rests against the inclined top frame 42, thereby causing the photovoltaic panel to tilt, i.e., one side of the telescopic rod retracts (the photovoltaic panel can slide downward between the guide wheel 43 and the conveyor belt 22 under the action of gravity).

[0028] like Figure 8-9As shown, the photovoltaic conveying section is equipped with a buffer component 5, which includes: an assembly frame, which is detachably assembled on the photovoltaic conveying section and includes a buffer frame 51 that is detachably fixed to the frame 1, on which a V-belt frame 52 is installed; a support frame 53, wherein the support frame 53 mounts two rollers 54 on the V-belt frame 52; a pressure-bearing component 57, wherein the pressure-bearing component 57 is detachably mounted on the V-belt frame 52; a buffer belt 56, which is sleeved on the pressure-bearing component 57 and the two rollers 54 to form a triangular structure, and the triangular structure of the buffer belt 56 can cause the pressure-bearing component 57 to deform under force; and a motor, wherein the motor is detachably mounted on the assembly frame, and the output end of the motor is connected to the rollers 54 by means of a sprocket and a chain 55. A buffer belt 56 is positioned on one side of the inclined photovoltaic panel. When the photovoltaic panel needs to be transported, the motor is started, driving the roller 54 to rotate. The roller 54 drives the buffer belt 56 to rotate, and the buffer belt 56, through friction with the photovoltaic panel, squeezes the pressure-bearing component 57, causing the buffer belt 56 to deform and tilt downwards to transport the photovoltaic panel. A buffer section 6, which can be an inflatable sphere, is provided on the frame 1. The inclined photovoltaic panel falls onto the buffer section 6 for cushioning, preventing the photovoltaic panel from directly impacting the conveyor belt 22. The pressure-bearing component 57 includes: a cylinder 571, which is fixed on the assembly frame. A round rod 572 is slidably inserted into the cylinder 571. A cylinder frame 573 is installed at the free end of the round rod 572. A pressure-bearing cylinder 574 is rotatably installed in the cylinder frame 573. A spring is fixedly installed between the cylinder 571 and the round rod 572. The buffer belt 56 is an elastic ring belt that contracts and deforms when the round rod 572 retracts into the cylinder 571.

[0029] Working principle: The solar photovoltaic panel to be tested is placed on the conveyor belt 22 of the conveying component 2 (it can be placed manually or by a robotic arm). The conveyor belt 22 is driven by a motor to transport the photovoltaic panel. When the photovoltaic panel is transported between two photovoltaic panel conveying sections, the guide component 4 sprays marking powder downwards evenly. The marking powder adheres to the photovoltaic panel. Then, the photovoltaic panel is transported again by the conveyor belt 22 on another photovoltaic conveying section. The photovoltaic panel is transported into the square cover 71 (at this time, the conveyor belt 22 stops working). Then, DC power is connected to the solar photovoltaic panel (it can be manually connected). The square cover 71 covers the photovoltaic panel to shield it from external light and prevent it from affecting the monitoring. An infrared camera captures images. A photovoltaic panel powered by direct current is photographed. Data captured by an infrared camera is imported into a computer. Analysis of color spots (abnormal brightness locations) drives a laser matrix 72 to generate high-energy lasers at corresponding positions, irradiating the photovoltaic panel surface. (Since computer color judgment is a standard procedure, and the laser matrix 72 consists of multiple evenly arranged high-energy laser probes, details are omitted here.) This causes the laser powder on the surface to change color, melt, and adhere to the photovoltaic panel surface for marking. The marked location accurately indicates the fault location. Flexible guide wheels 43 can clamp the photovoltaic panel, restricting the photovoltaic delivery position. The tilted top frame 42 ensures that the guide wheels 43 clamping the photovoltaic panels on both sides are also tilted, causing the photovoltaic panel to tilt as well. The tilted photovoltaic panel is coated... When applying laser powder, it allows the powder to slide freely and spread relatively evenly, thus preventing powder accumulation. An external air pump can be connected to the core tube 453 port, blowing air into the core tube 453. The core cylinder 452 has an openable material door on its side, through which laser powder is added. Air is blown into the core cylinder 452 from the core tube 453, increasing the air pressure and causing the laser powder to spray out from the powder outlet. The sprayed laser powder coats the surface of the transported photovoltaic panel. When the photovoltaic panel is transported between the two sets of guide wheels 43, it drives the conveyor wheels to rotate. The rotation of the conveyor wheels drives the input end of the bevel gear set 44 to rotate (i.e., one bevel gear rotates), which in turn drives the output end of the bevel gear set 44 (i.e., the central shaft of the other bevel gear rotates). A pulley, driven by a belt, rotates the core cylinder 452. During this rotation, the core cylinder 452 vibrates due to continuous scraping by the lifting rod (reducing the probability of laser powder clogging). This allows the laser powder in the core cylinder 452 to continuously exit from the lower powder outlet. When a photovoltaic panel is being conveyed from one photovoltaic panel conveyor to another (i.e., when the photovoltaic panel is between two photovoltaic panel conveyors, the conveyor belts 22 in both conveyors stop), the cylinder 31 lifts the assembly plate 34 upwards. The assembly plate 34 drives the sliding rod 33 upwards, causing the conveying component 2 to carry the photovoltaic panel upwards. This allows the photovoltaic panel to rest against the inclined top frame 42, causing the photovoltaic panel to tilt.When one telescopic rod retracts (the photovoltaic panel can slide downwards between the guide wheel 43 and the conveyor belt 22 under gravity), the buffer belt 56 blocks one side of the inclined photovoltaic panel. When the photovoltaic panel needs to be conveyed, the motor is started, and the motor drives the roller 54 to rotate. The roller 54 drives the buffer belt 56 to rotate. The buffer belt 56, with the friction between itself and the photovoltaic panel, squeezes the pressure member 57, causing the buffer belt 56 to deform and tilt downwards to convey the photovoltaic panel. The frame 1 is equipped with a buffer part 6, which can be an inflatable sphere. The inclined photovoltaic panel falls onto the buffer part 6 for cushioning, preventing the photovoltaic panel from directly impacting the conveyor belt 22.
