Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic panel production, specifically a photovoltaic panel angle adjustment device with a limiting function. Background Technology

[0002] A photovoltaic (PV) panel is a device that converts solar energy into electrical energy through the photovoltaic effect. It consists of multiple photovoltaic cell units. In the production process of PV modules, the framed modules are usually transported with the back facing up. However, when conducting power tests, the modules need to be flipped. Therefore, in order to facilitate the angle adjustment of the PV panel, an angle adjustment device is required. Existing angle adjustment devices usually require multiple drive structures, which makes the installation and maintenance costs high.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent with publication number CN116692417A, publication date September 5, 2023) provides a photovoltaic panel soft-edge module flipping device, which includes a clamping unit, a rotary cylinder unit, and a rotary unit. The clamping unit is disposed on the rotary unit and is driven to flip by the rotary cylinder unit. The clamping unit is used to clamp the photovoltaic panel soft-edge module. The clamping unit includes a clamping cylinder, a mounting plate, a pressure equalizing plate, and a guide structure. The mounting plate is fixed on the rotary unit, and at least two guide structures are spaced apart on the mounting plate. The cylinder body of the clamping cylinder is fixedly connected to the mounting plate, and the push rod of the clamping cylinder is fixedly connected to the pressure equalizing plate. This device distributes the thrust of the clamping cylinder evenly through the pressure equalizing plate and the pressure plate, and combined with the buffering effect of the rectangular spring, makes the clamping unit clamp more evenly and ensures clamping stability.

[0004] While existing technologies simplify the drive structure by rotating the photovoltaic panel, the numerous clamping unit components increase maintenance difficulty in practical applications. Furthermore, the poor stability of the equalizing plate and rectangular springs can lead to displacement or rotational instability of the photovoltaic panel, thereby affecting overall performance and operational reliability.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on existing photovoltaic panel angle adjustment equipment with limiting functions. Therefore, we propose that photovoltaic panel angle adjustment equipment with limiting functions can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a photovoltaic panel angle adjustment device with a limiting function, in order to solve the problem mentioned in the background art that the current market uses a rotary unit to flip the photovoltaic panel to simplify the drive structure, but in actual application, there are many clamping unit components, which increases the maintenance difficulty. The stability of the pressure equalization plate and rectangular spring is poor, which leads to displacement or rotational instability of the photovoltaic panel, thereby affecting the overall performance and operational reliability.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic panel angle adjustment device with a limiting function, comprising a frame, a flipping mechanism on the frame, the flipping mechanism including a stepper motor and a worm gear reducer, the output end of the stepper motor being connected to a guide frame, a support frame on the guide frame, the support frames being symmetrically arranged, a conveyor roller on the frame, an upper conveyor belt structure and a lower conveyor belt structure on the support frame, and a pneumatic rotary blocking mechanism on the support frame, the pneumatic rotary blocking mechanism including a rotary cylinder and a blocking roller assembly, the pneumatic rotary blocking mechanism being located at the front and rear ends of the support frame.

[0008] Preferably, the support frame is equipped with sensors for monitoring. The sensors are located on the front and rear sides of the support frame and are used to detect the entry of material, as well as to detect the arrival of material and the deceleration of the transmission.

[0009] Preferably, a deceleration mechanism assembly is installed on the support frame, the deceleration mechanism assembly including a hydraulic buffer installed on the support frame.

[0010] Preferably, the support frame is provided with a cylinder clamping mechanism, which includes a support seat mounted on the support frame.

[0011] Preferably, a buffer pad is connected to the support base via a connector. The buffer pad is used to prevent the photovoltaic panel from being damaged by swaying within the upper and lower transmission belt structures.

[0012] Preferably, the support frame is provided with an auxiliary component, the auxiliary component including an auxiliary frame installed on the support frame, the auxiliary frame being connected to the support frame by a bolt structure.

[0013] Preferably, the support frame is equipped with an air pump, the output end of which is connected to a suction cup via a delivery pipe, and the auxiliary frame is equipped with a telescopic cylinder.

[0014] Preferably, a suction cup is installed at the bottom of the telescopic cylinder, the conveying pipe is connected to the inner cavity of the suction cup, a through groove is opened at the bottom end of the suction cup, and a rubber sheet is installed inside the through groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This photovoltaic panel angle adjustment device with limiting function allows for convenient signal transmission via sensors. The rotary cylinder drives the blocking roller assembly to rotate to the working position, forming a blockage from both the front and rear ends. This reduces the problem of poor stability caused by using springs for limiting, improves the overall operational reliability, and has a simple overall structure, solving the problem of increased maintenance difficulty caused by complex components. The specific details are as follows: The equipment uses sensors on the front and rear sides of the support frame to achieve phased identification. When the photovoltaic panel enters about one-third of the way, the presence of material is detected and the conveyor belt is started. When it enters about four-fifths of the way, the material is detected and the conveyor belt is decelerated. Through the coordinated support of the conveyor rollers and the upper and lower conveyor belt structures, the stability of the photovoltaic panel transmission path is ensured, which further improves the accuracy of the overall transmission process.

[0016] The equipment adopts a triple fixing method consisting of a pneumatic rotating blocking mechanism, a cylinder pressing mechanism, and auxiliary components. The auxiliary components use an air pump and conveying pipes to create negative pressure on the suction cups, which, together with the telescopic cylinder, are used to fix the photovoltaic panels in place. This multi-dimensional fixing effectively prevents the photovoltaic panels from swaying between the conveyor belts and reduces the probability of damage to the photovoltaic panels.

[0017] The stepper motor in the flipping mechanism, in conjunction with the worm gear reducer, can precisely control the power output and drive the guide frame and the symmetrical support frame to rotate synchronously. During the flipping process, the hydraulic buffer on the support frame can absorb the inertial force, slow down the rotation speed, and prevent collisions due to excessive speed when flipping into place, thus ensuring the safety of the photovoltaic panel during the angle adjustment process.

[0018] The auxiliary components on the support frame are symmetrically arranged, and the auxiliary frame is connected by a bolt structure. The position can be adjusted according to the size and thickness of the photovoltaic panel. The negative pressure of the air pump and the extension stroke of the telescopic cylinder can be adjusted as needed, which improves the versatility and adaptability of the equipment and reduces the cost of equipment replacement for enterprises.

[0019] This equipment requires minimal human intervention throughout the entire process. All components operate automatically through signal linkage. Sensor signals can automatically trigger the start, stop, and deceleration of the conveyor belt. Automated operation not only reduces errors from manual operation but also shortens the operation time for a single angle adjustment. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: In this example, the rotary cylinder 9 drives the blocking roller assembly 10 to rotate to the working position, forming a barrier from both the front and rear ends to limit the horizontal displacement of the photovoltaic panel. This reduces the instability problem caused by using springs for limiting the position. Figures 1-3The technical solution shown includes a frame 1 with a tilting mechanism 2 mounted on it. The tilting mechanism 2 includes a stepper motor and a worm gear reducer, and the output end of the stepper motor is connected to a guide frame 3. A support frame 4 is mounted on the guide frame 3, and the support frames 4 are symmetrically arranged. A conveyor roller 5 is mounted on the frame 1, and an upper conveyor belt structure 7 and a lower conveyor belt structure 8 are mounted on the support frame 4. A pneumatic rotary blocking mechanism is mounted on the support frame 4, including a rotary cylinder 9 and a blocking roller assembly 10. The pneumatic rotary blocking mechanism is located at the front and rear ends of the support frame 4. Sensors 6 for monitoring are mounted on the support frame 4, located on both the front and rear sides. The sensors 6 are used to detect the entry of material, identify the position, and decelerate the transmission. The photovoltaic panel first enters the equipment area via the conveyor roller 5 on the frame 1, triggering the sensors 6 on both the front and rear sides of the support frame 4. When the photovoltaic panel has entered about one-third of its length, the sensors 6 detect the entry of material and send signals to the upper conveyor belt structure 7 and the lower conveyor belt structure 8. The system starts and supports the photovoltaic panel. When the photovoltaic panel is about four-fifths of the way in, sensor 6 identifies it as in position for the second time and sends a signal to decelerate the upper and lower conveyor belt structures 7 and 8 to prevent the photovoltaic panel from impacting the equipment due to inertia. After the upper and lower conveyor belt structures 7 and 8 stop decelerating, the pneumatic rotating blocking mechanisms at the front and rear ends of the support frame 4 are activated. The rotating cylinder 9 drives the blocking roller group 10 to rotate to the working position, forming a blockage from both ends to limit the horizontal displacement of the photovoltaic panel. This reduces the instability caused by using springs for limiting and improves the overall reliability of operation. After the photovoltaic panel is completely fixed to the auxiliary components by the cylinder clamping mechanism, the flipping mechanism 2 is activated. The stepper motor outputs power, which is decelerated by the worm gear reducer and drives the guide frame 3 to rotate. The guide frame 3 is rigidly connected to the symmetrically arranged support frame 4, thereby driving the photovoltaic panel to flip synchronously. After flipping 180 degrees, the flipping mechanism 2 stops working to ensure accurate positioning of the photovoltaic panel angle. The overall structure is simple and solves the problem of increased maintenance difficulty caused by setting complex components.

[0024] Example 2: In this example, the deceleration mechanism on the support frame 4 functions, and the hydraulic buffer 11 absorbs the inertial force of the flipping motion, slows down the rotation speed, and prevents the photovoltaic panel from colliding due to excessive speed when flipping into position, thus improving the overall stability of the flipping motion. Specifically, as follows... Figures 1-4As shown, a deceleration mechanism assembly is installed on the support frame 4. The deceleration mechanism assembly includes a hydraulic buffer 11 installed on the support frame 4. A cylinder pressing mechanism is provided on the support frame 4. The cylinder pressing mechanism includes a support seat 12 installed on the support frame 4. A buffer pad 14 is connected to the support seat 12 through a connector 13. The buffer pad 14 is used to prevent the photovoltaic panel from swaying and being damaged within the upper conveyor belt structure 7 and the lower conveyor belt structure 8. When the cylinder pressing mechanism on the support frame 4 is working, the support seat 12 drives the buffer pad 14 to move towards the photovoltaic panel through the connector 13, adhering to and pressing the photovoltaic panel frame, preventing it from swaying between the upper conveyor belt structure 7 and the lower conveyor belt structure 8. During the flipping process, the deceleration mechanism assembly on the support frame 4 plays a role. The hydraulic buffer 11 absorbs the inertial force of the flipping, slows down the rotation speed, and prevents the photovoltaic panel from colliding due to excessive speed when flipping into position, thus improving the overall stability of the flipping.

[0025] Example 3: In this example, the rubber sheet 20 in the groove at the bottom of the suction cup 18 increases the friction, making the adsorption more stable and thus making the whole structure more stable. Specifically, as shown below... Figure 1 , Figure 5 and Figure 6 As shown, the support frame 4 is equipped with auxiliary components, including an auxiliary frame 15 mounted on the support frame 4. The auxiliary frame 15 is connected to the support frame 4 by bolts. An air pump 16 is mounted on the support frame 4, and the output end of the air pump 16 is connected to a suction cup 18 via a delivery pipe 17. A telescopic cylinder 19 is mounted on the auxiliary frame 15, and the suction cup 18 is mounted at the bottom of the telescopic cylinder 19. The delivery pipe 17 is connected to the inner cavity of the suction cup 18. A through groove is formed at the bottom of the suction cup 18, and a rubber sheet 20 is installed inside the through groove. The air pump 16 on the support frame 4 draws air into the inner cavity of the suction cup 18 through the delivery pipe 17 to create negative pressure. The telescopic cylinder 19 on the auxiliary frame 15 pushes the suction cup 18 to adhere to the surface of the photovoltaic panel, further enhancing the fixing effect. The rubber sheet 20 in the bottom groove of 18 increases friction, making the adsorption more stable and thus the overall stability more complete. The auxiliary components are symmetrically arranged, making it convenient to use according to the required fixing effect. After the overall flipping is completed, the rotary cylinder 9 of the pneumatic rotary blocking mechanism drives the blocking roller group 10 to reset, the buffer pad 14 of the cylinder pressing mechanism retracts, the suction cup 18 of the auxiliary components is depressurized, and the telescopic cylinder 19 drives the suction cup 18 to rise, releasing the fixation of the photovoltaic panel. Then, the upper conveyor belt structure 7 and the lower conveyor belt structure 8 start in opposite directions, and the photovoltaic panel is conveyed out of the equipment via the conveyor roller 5, completing one angle adjustment operation. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
