Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel production technology, and in particular to a gluing device for the production of solar photovoltaic panels. Background Technology

[0002] With the continuous growth of global demand for renewable energy, the market demand for solar photovoltaic panels, as an important component of clean energy, is also steadily increasing. In the manufacturing process of photovoltaic panels, the adhesive coating process is one of the key steps to ensure the quality and performance of the modules. Adhesive coating not only bonds different modules together but also plays a role in electrical insulation, waterproofing and dustproofing, thermal management, and filling gaps, having a crucial impact on the mechanical strength and durability of the product. To meet increasingly stringent environmental standards and ever-increasing production efficiency requirements, the photovoltaic panel manufacturing industry is developing towards automation and precision.

[0003] Currently, the adhesive coating process for solar photovoltaic panels mainly relies on manual operation or semi-automated equipment. While manual adhesive coating is simple and direct, it requires a large amount of manpower and depends heavily on the skill level of the workers. With technological advancements, automated adhesive coating systems have emerged on the market. These systems can partially automate the adhesive coating process, reducing manual intervention and improving work efficiency. Automated adhesive coating systems typically include a conveyor belt, an adhesive coating head, and a control system. They can complete the adhesive coating task according to a preset program. In addition, some advanced adhesive coating equipment is equipped with a vision recognition system to ensure the accuracy of the adhesive application location.

[0004] Although existing coating technologies and equipment have improved production efficiency to some extent, many problems still exist in practical applications. On the one hand, traditional coating methods, whether manual or semi-automatic, face the challenge of low efficiency and cannot meet the rapid response requirements of large-scale production. On the other hand, in terms of precision, due to the lack of fine coordinate adjustment capabilities, existing coating systems struggle to achieve high-precision coating, which may lead to coating position deviations and affect the quality of subsequent processes. Most importantly, existing equipment lacks flexibility and has poor adaptability to photovoltaic panels of different specifications and shapes, limiting its application in diversified production. Utility Model Content

[0005] The purpose of this invention is to provide a gluing device for the production of solar photovoltaic panels, which can achieve high-precision and automated gluing, adapt to various specifications of photovoltaic panels, and improve production efficiency and product quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gluing device for solar photovoltaic panel production, comprising a frame and a conveying mechanism for conveying photovoltaic panels, characterized in that: the frame includes two columns and a support plate, the support plate is fixed to the top of the two columns, the conveying mechanism is disposed below the support plate, a movable seat capable of moving left and right is disposed above the support plate, an mounting plate is fixed on the movable seat, a lifting plate capable of moving up and down is disposed on the mounting plate, a mixing valve for applying glue is fixed on the lifting plate, the mixing valve is provided with a first glue inlet, a second glue inlet and a glue outlet, a curing chamber with an opening at the lower end is fixed to the lower end of the support plate, and an ultraviolet curing lamp is installed in the curing chamber.

[0007] Preferably, a translation drive mechanism for driving the movable seat to move left and right is provided between the movable seat and the support plate. The translation drive mechanism includes a drive motor, a drive screw, and a nut seat. Two bearing seats are fixed at a distance from the upper end of the support plate. The drive screw is rotatably connected between the two bearing seats. The drive motor is fixed to one side of the support plate through a motor support, and the output shaft of the drive motor is coaxially fixed with the drive screw. The nut seat is threadedly connected to the drive screw and is fixed to the movable seat. A guide assembly is also provided between the movable seat and the support plate.

[0008] Preferably, a lifting mechanism for driving the lifting plate to move up and down is provided between the lifting plate and the movable seat. The lifting mechanism includes a lifting cylinder, which is vertically fixed to one side of the movable seat, and the piston rod of the lifting cylinder is fixed to the lifting plate. A guide unit is also provided between the movable seat and the lifting plate.

[0009] Preferably, the support plate is further provided with a photoelectric sensor for detecting whether there is a photovoltaic panel on the conveying mechanism. The photoelectric sensor is electrically connected to a control module, and an alarm that is electrically connected to the control module is also fixed on the support plate.

[0010] Preferably, the conveying mechanism includes a conveying bracket, a conveying motor, two rollers, and a conveyor belt. The conveying bracket is disposed between two columns and below the support plate. The two rollers are rotatably disposed at both ends of the conveying bracket. The conveyor belt is wound between the two rollers. The conveying motor is fixed on the conveying bracket and is used to rotate one of the rollers.

[0011] Preferably, the curing chamber has openings at both the front and rear ends for the conveyor belt to pass through.

[0012] Preferably, the first glue inlet is connected to the first glue tank via a first glue pump, and the second glue inlet is connected to the second glue tank via a second glue pump.

[0013] Compared with existing technologies, the advantages of this utility model are as follows: This glue coating device forms a stable basic structure through the columns and support plates on the frame, realizing the spatial optimization layout of the glue coating system. Its core innovation lies in the adoption of a dual-axis moving mechanism that combines a movable seat that can move left and right with a lifting plate that can move up and down. This design significantly improves the accuracy and flexibility of the glue coating process. The glue mixing valve on the device has a design with two glue inlets and one glue outlet, which can realize the precise proportioning and mixing of multi-component glues, effectively ensuring the stability of the glue coating quality. A curing chamber is set below the glue coating station and equipped with an ultraviolet curing lamp, forming a complete glue coating-curing process chain. This integrated design not only saves the transfer time between processes, but also ensures that the glue layer is cured in time under optimal conditions. The setting of the conveying mechanism enables the entire process to be carried out continuously, improving production efficiency.

[0014] The significant advantages of this design are: it achieves high-precision control of the adhesive application position, meets the adhesive application requirements of photovoltaic panels of different specifications, greatly reduces manual intervention through automated operation, improves production efficiency and product quality consistency, and the compact integrated design also optimizes the space utilization of the production line.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Example 1: As shown in the figure, a coating device for solar photovoltaic panel production includes a frame 3 and a conveying mechanism 4 for conveying photovoltaic panels. The frame 3 includes two columns 1 and a support plate 2. The support plate 2 is fixed to the top of the two columns 1. The conveying mechanism 4 is located below the support plate 2. A movable seat 5 that can move left and right is provided above the support plate 2. An mounting plate 6 is fixed on the movable seat 5. A lifting plate 7 that can move up and down is provided on the mounting plate 6. A mixing valve 8 for coating is fixed on the lifting plate 7. The mixing valve 8 is provided with a first glue inlet 9, a second glue inlet 10 and a glue outlet 11. A curing chamber 12 with an opening at the bottom is fixed at the lower end of the support plate 2. An ultraviolet curing lamp is installed in the curing chamber 12.

[0023] The working process of this device is as follows: The photovoltaic panel to be coated is conveyed to a designated position below the support plate 2 via the conveying mechanism 4. The system controls the moving seat 5 to move laterally on the support plate 2, while simultaneously controlling the lifting plate 7 to move vertically, thereby achieving precise positioning of the mixing valve 8 in three-dimensional space. When the mixing valve 8 moves to the preset coating start position, two different components of adhesive are input into the mixing valve 8 from the first adhesive inlet 9 and the second adhesive inlet 10, respectively. After being fully mixed inside the mixing valve 8, they are sprayed onto the designated position of the photovoltaic panel from the adhesive outlet 11. As the moving seat 5 continues to move, the mixing valve 8 can complete a continuous and uniform coating operation on the surface of the photovoltaic panel according to the preset coating trajectory. After coating is completed, the conveying mechanism 4 conveys the photovoltaic panel to the curing chamber 12 below. During this process, the ultraviolet curing lamp in the curing chamber 12 is activated to irradiate the area that has just been coated with ultraviolet light, causing the adhesive layer to cure rapidly. Once a photovoltaic panel has been coated and cured, the conveying mechanism 4 transports it out of the curing chamber 12, while simultaneously transporting the next photovoltaic panel to be coated into the working position. This cycle repeats continuously to achieve continuous production.

[0024] Example 2: As shown in the figure, unlike Example 1, a translation drive mechanism 14 for driving the movable seat 5 to move left and right is provided between the movable seat 5 and the support plate 2. The translation drive mechanism 14 includes a drive motor 15, a drive screw 16 and a nut seat 17. Two bearing seats 18 are fixed at intervals at the upper end of the support plate 2. The drive screw 16 is rotatably connected between the two bearing seats 18. The drive motor 15 is fixed to one side of the support plate 2 through a motor support 19, and the output shaft of the drive motor 15 is coaxially fixed with the drive screw 16. The nut seat 17 is threadedly connected to the drive screw 16 and is fixed to the movable seat 5. A guide assembly 20 is also provided between the movable seat 5 and the support plate 2.

[0025] The device employs a precision lead screw drive system to achieve smooth left and right movement of the movable seat 5. Specifically, the drive motor 15 is securely mounted on the side of the support plate 2 via a motor support 19, and its output shaft is coaxially connected to the drive lead screw 16, ensuring direct and efficient power transmission. The two ends of the drive lead screw 16 form a reliable support structure with the support plate 2 via bearing seats 18. This design not only ensures the rotational stability of the lead screw but also effectively reduces vibration during movement.

[0026] When the drive motor 15 is running, it drives the drive screw 16 to rotate. The nut seat 17, which is threaded onto the screw, will move in a horizontal linear motion as the screw rotates. Since the nut seat 17 is fixed to the movable seat 5, it can drive the movable seat 5 to move precisely left and right. At the same time, the guide component 20 further enhances the stability and accuracy of the movement of the movable seat 5, effectively preventing deviation and shaking during the movement.

[0027] The advantages of this transmission structure are: by converting rotary motion into linear motion through lead screw transmission, it not only achieves high-precision position control, but also has a self-locking function to ensure that the position is maintained when the machine stops. At the same time, the adjustable speed of the motor also makes it possible to accurately control the glue application speed.

[0028] Preferably, a lifting mechanism 21 for driving the lifting plate 7 to move up and down is provided between the lifting plate 7 and the movable seat 5. The lifting mechanism 21 includes a lifting cylinder 22, which is vertically fixed on one side of the movable seat 5. The piston rod 23 of the lifting cylinder 22 is fixed to the lifting plate 7. A guide unit 24 is also provided between the movable seat 5 and the lifting plate 7.

[0029] The device employs a pneumatic lifting system to achieve precise vertical movement control of the lifting plate 7. During operation, the lifting cylinder 22 is securely and vertically mounted on one side of the movable seat 5. When the height of the mixing valve 8 needs adjustment, the control system supplies compressed air to the lifting cylinder 22, causing its piston rod 23 to extend and retract. Since the piston rod 23 is fixed to the lifting plate 7, it can drive the lifting plate 7 to move smoothly up and down. In this process, the guide unit 24 plays a guiding and stabilizing role. It not only ensures the precise vertical trajectory of the lifting plate 7 but also effectively prevents possible swaying and deviation during lifting.

[0030] The design of this pneumatic lifting mechanism 21 features fast response, precise control, simple structure, and convenient maintenance. At the same time, the stroke of the cylinder can be adjusted according to actual needs to meet the requirements of different adhesive application heights, providing a reliable height adjustment guarantee for the entire adhesive application process.

[0031] Preferably, the support plate 2 is also provided with a photoelectric sensor 25 for detecting whether there is a photovoltaic panel on the conveying mechanism 4. The photoelectric sensor 25 is electrically connected to a control module 26. An alarm 27 electrically connected to the control module 26 is also fixed on the support plate 2.

[0032] This device integrates a photoelectric sensor 25 and an alarm 27 on the support plate 2, constructing an intelligent real-time monitoring system. During operation, the photoelectric sensor 25 (which can be an Omron E3Z-T61 series or a Keyence PZ-G42 series photoelectric sensor 25) continuously monitors the presence status of the photovoltaic panels on the conveyor mechanism 4. When the photovoltaic panels are correctly positioned, the photoelectric sensor 25 transmits a signal to the control module 26 (which can be a Siemens S7-200 SMART PLC or a Mitsubishi FX3U series PLC) for processing. If an abnormality is detected, such as the photovoltaic panel not being in place, being misaligned, or missing, the control module 26 immediately triggers the alarm 27 (which can be a Panasonic PM-L54 or Banner K50 series warning light) to emit an audible and visual alarm signal, reminding the operator to handle the situation promptly.

[0033] The advantages of this design are: it enables real-time monitoring of the production process, effectively prevents glue application errors caused by inaccurate positioning of photovoltaic panels, significantly improves the level of automation in production and the reliability of product quality, and the timely response of the alarm system greatly reduces the risk of material waste and equipment damage caused by misoperation, thereby improving production efficiency and economic benefits.

[0034] Example 3: As shown in the figure, unlike Example 2, the conveying mechanism 4 includes a transmission bracket 28, a transmission motor 29, two rollers 30, and a transmission belt 31. The transmission bracket 28 is set between two columns 1 and located below the support plate 2. The two rollers 30 are rotatably set at both ends of the transmission bracket 28. The transmission belt 31 is wound between the two rollers 30. The transmission motor 29 is fixed on the transmission bracket 28 and is used to rotate one of the rollers 30.

[0035] In the above design, the transmission bracket 28 is securely installed between the two columns 1 and below the support plate 2, providing a solid foundation for the entire transmission system. Two rollers 30 are respectively installed at both ends of the transmission bracket 28. One roller 30 is directly connected to the transmission motor 29 (either a Teco MS series or a Siemens 1LE0 series geared motor) as the driving wheel, and the other roller 30 is the driven wheel. The two are connected by a synchronous belt (a wear-resistant PVC conveyor belt or a polyurethane synchronous belt can be used) to form a ring transmission system.

[0036] When the transmission motor 29 starts, the drive roller 30 rotates, driving the transmission belt 31 to move continuously, thereby achieving stable transportation of photovoltaic panels. The advantages of this transmission mechanism are: simple and reliable structure, convenient maintenance, and the width and length of the transmission belt 31 can be flexibly customized according to the size of the photovoltaic panels to ensure transportation stability. At the same time, by adjusting the speed of the transmission motor 29, the transportation speed of the photovoltaic panels can be precisely controlled, forming a good match with the gluing process and improving production efficiency. In addition, the surface of the transmission belt 31 can be specially treated with anti-slip treatment as needed to enhance the friction between it and the photovoltaic panels, prevent slippage during transportation, and ensure transportation accuracy.

[0037] Preferably, the front and rear ends of the curing chamber 12 are provided with notches 32 for the conveyor belt 31 to pass through.

[0038] The curing chamber 12 has openings 32 at both its front and rear ends for the conveyor belt 31 to pass through, forming a semi-enclosed curing space structure. This design allows the conveyor belt 31 to continuously pass through the curing chamber 12, achieving uninterrupted transport of photovoltaic panels, while ensuring relatively stable environmental conditions inside the curing chamber 12. When the coated photovoltaic panels enter the curing chamber 12 with the conveyor belt 31, ultraviolet curing lamps irradiate and cure the adhesive layer. The enclosed structure of the curing chamber 12 effectively prevents ultraviolet leakage, protects the safety of operators, and improves curing efficiency.

[0039] Preferably, the first glue inlet 9 is connected to the first glue tank 34 via the first glue pump 33, and the second glue inlet 10 is connected to the second glue tank 36 via the second glue pump 35.

[0040] The device employs an independent glue supply system with dual glue pumps and dual glue tanks, achieving proportional delivery and mixing of two different glue components through precise flow control. Specifically, the glue component in the first glue tank 34 is precisely metered by the first glue pump 33 and delivered to the first glue inlet 9 of the mixing valve 8, while the other component of the glue in the second glue tank 36 is delivered to the second glue inlet 10 by the second glue pump 35.

[0041] Both glue pumps can independently adjust their output pressure and flow rate, ensuring that the two glue components are precisely mixed according to the preset ratio. The advantages of this design are: by storing and transporting the two components separately, the glue is prevented from curing during storage, thus extending the glue's service life; the independent control of the dual pumps makes the mixing ratio more accurate, and the mixing ratio can be flexibly adjusted according to the needs of different products; at the same time, when a certain component of glue is insufficient, it can be replenished separately, improving the flexibility and economy of the production process.

[0042] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
