Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel production technology, and more specifically, to a rapid testing device for photovoltaic panel production. Background Technology

[0002] In the production process of photovoltaic panels, quality control of raw silicon wafers is one of the key aspects. The thickness uniformity of silicon wafers has a significant impact on the photoelectric conversion efficiency of photovoltaic panels. To ensure the accuracy of test results, thorough cleaning of the silicon wafer surface is an essential operation before thickness uniformity testing. Existing testing devices generally use nitrogen purging to clean the silicon wafer surface. Nitrogen has the advantages of chemical stability and is not prone to reacting with silicon wafers, effectively avoiding physical or chemical damage to the silicon wafer surface, thus protecting the surface integrity of the silicon wafer and ensuring the smooth progress of subsequent production processes. However, this seemingly effective cleaning method has serious drawbacks. During nitrogen purging, although dust and other impurities on the silicon wafer surface can be blown away, this blown dust will spread freely in the workshop environment. On the one hand, this causes serious pollution to the production site environment; on the other hand, the spread of dust can easily contaminate adjacent silicon wafer raw materials. In view of this, we propose a rapid testing device for photovoltaic panel production. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a rapid testing device for photovoltaic panel production, so as to solve the technical problem that dust is easily spread during the pre-cleaning process of silicon wafers in the current testing device.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rapid testing device for photovoltaic panel production, comprising a thickness testing equipment body, a conveyor belt at the input end of the thickness testing equipment body, a placement plate on the conveyor belt, a groove for placing silicon wafers on the top of the placement plate, an infrared detection part on one side of the conveyor belt, an output part in the output direction of the conveyor belt, two side plates installed on the top of the conveyor belt, a collection frame on the top of the two side plates, a hydraulic rod fixed to the collection frame embedded inside the side plate, a cavity in the side wall of the collection frame, multiple spoon shells inside the cavity, multiple suction structures in the center of the collection frame, a driving structure in the upper half of the collection frame, and a gas port for connecting to external nitrogen installed on the top of the collection frame.

[0005] Preferably, the collection frame is made of a material that can isolate static electricity, and a guide plate is integrally formed on the bottom edge of the collection frame. The cross-section of the guide plate is a curved structure that guides the gas to the cavity. Filter plates communicating with the cavity are installed on the four sides of the upper half of the collection frame.

[0006] Preferably, the multiple spoon shells are arranged in multiple rows at equal intervals, with each row staggered. Each spoon shell consists of a bottom spoon plate and an inner spoon part. The bottom spoon plate is made of ceramic material, and the inner spoon part is made of nylon material.

[0007] Preferably, the attraction structure includes a central rod rotatably connected to the collection frame, a plurality of connecting posts fixed to the outer periphery of the central rod, the center of the connecting posts being made of metal and the outer surface of the connecting posts being made of rubber, an electrostatic ring being movably connected to the outer periphery of the connecting posts, and a propeller being installed at the bottom of the central rod.

[0008] Preferably, a plurality of electrostatic balls are fixed on the outer periphery of the electrostatic ring, one end of each electrostatic ball is spherical, and the surface of the spherical ball has a plurality of inner dust cavities for accommodating dust. Both the electrostatic ring and the electrostatic balls are made of rubber, and the electrostatic balls can contact the inner spoon when rotating.

[0009] Preferably, the drive structure includes multiple gears, which are fixed to the top of the central rod. The outer four sides of the drive gear mesh with the corresponding central rod, and a drive motor is mounted at the center of the drive gear.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model installs a side plate and a collection frame on the top of the conveyor belt, and uses nitrogen gas to blow away dust on the surface of silicon wafers. With the curved structure of the guide plate, the dust can be guided into the cavity of the collection frame, which prevents the dust from spreading freely in the workshop environment, effectively protects the production site environment, reduces the pollution of adjacent silicon wafer raw materials, and solves the problem of dust diffusion that easily occurs during the pre-cleaning process of silicon wafers by the testing device.

[0012] 2. This utility model also utilizes multiple rows of equally spaced and staggered spoon shells within the cavity to collect and hold falling dust. The spoon shells feature a ceramic bottom plate and a nylon inner spoon. Combined with the static electricity generated by the friction between the electrostatic ball and the inner spoon in the attraction structure, dust is adsorbed into the dust cavity within the spoon shells and the electrostatic ball, preventing it from falling out and achieving centralized dust collection. When cleaning is required, simply stop rotating and remove the collection frame; once the static electricity dissipates, cleaning can proceed. This convenient operation further solves the problem of dust diffusion during the pre-cleaning process of silicon wafers in testing devices.

[0013] 3. This utility model also utilizes a drive structure with multiple meshing gears. The drive motor drives the active gear, which in turn causes multiple central rods to rotate. Adjacent central rods rotate in opposite directions, and adjacent propellers are arranged in opposite directions. This ensures that multiple propellers can effectively attract dust into the cavity, further enhancing the dust collection effect and improving the overall performance of the device.

[0022] like Figures 1 to 7 As shown, the rapid testing device for photovoltaic panel production involved in this utility model is an innovative device specially designed for the needs of silicon wafer thickness testing and surface cleaning in the photovoltaic panel production process.

[0023] The device centers on a thickness detection equipment body 1, which employs an advanced industrial-grade design, boasting high-precision detection performance and stable, reliable operation. A conveyor belt 2 is installed at the input end of the body 1. Made of high-strength, wear-resistant rubber, the conveyor belt 2 ensures no wear or deformation during prolonged operation, guaranteeing the stability of silicon wafer transport. A placement plate 3, made of aluminum alloy, is placed on the conveyor belt 2. Its top has a groove specifically designed for placing silicon wafers; the groove's size and shape are precisely designed to closely conform to the wafer's shape, effectively preventing displacement or shaking during transport. An infrared detection unit 4 is located on one side of the conveyor belt 2. Equipped with a high-sensitivity infrared sensor and sophisticated signal processing circuitry, the unit emits infrared light and detects its reflection height. The infrared detection unit 4 can accurately measure the thickness of the silicon wafer, providing key data support for quality control in the photovoltaic panel production process. The output section 5 is provided in the output direction of the conveyor belt 2. The output section 5 consists of a lifting plate 501, a lifting cylinder 502, a horizontal conveyor belt 503, and a vertical conveyor belt 504. The lifting cylinder 502 adopts high-performance pneumatic components, which have strong thrust and precise control performance. Through the operation of the lifting cylinder 502, the lifting plate 501 can be smoothly raised to the required height, ensuring that the lifting plate 501 is flush with the conveyor belt 2 and achieving seamless docking. Subsequently, the horizontal conveyor belt 503 and the vertical conveyor belt 504 run in sequence, smoothly conveying the placement plate 3 out of the detection area and completing the entire detection process. These basic detection structures all adopt mature existing technologies, and their stable performance and efficient operation lay a solid foundation for the overall function realization of the device.

[0024] Dust collection and treatment structure:

[0025] Collection Frame and Related Structure: To prevent dust from scattering and polluting the production environment during nitrogen purging of the silicon wafer surface, two side plates 6 are installed on the top of the conveyor belt 2. The side plates 6 are made of stainless steel, possessing good strength and corrosion resistance, effectively preventing dust from spreading. A collection frame 7 is installed on top of the two side plates 6. The collection frame 7 is made of a special engineering plastic material that can isolate static electricity, effectively preventing dust from adhering to the surface of the collection frame 7 due to static electricity, thus affecting the collection effect. An air inlet 12 is installed on the top of the collection frame 7, connecting to the external nitrogen supply system via a pressure-resistant and corrosion-resistant pipe, ensuring stable and efficient nitrogen input into the collection frame 7. A hydraulic rod 8, which is fixed to the collection frame 7, is embedded inside the side plates 6. The hydraulic rod 8 is made of high-strength... Made of high-strength alloy steel, the height of the collection frame 7 can be flexibly adjusted by its telescopic movement to adapt to the testing needs of silicon wafers of different thicknesses. The side wall of the collection frame 7 has a cavity, which provides storage space for dust collection. The bottom edge of the collection frame 7 is integrally formed with a guide plate 13, which is made of stainless steel and has a carefully designed curved structure. When nitrogen gas is introduced into the air port 12 to blow away the dust on the surface of the silicon wafer, the dust will be guided into the cavity along the curved structure of the guide plate 13 by the nitrogen gas flow. The upper half of the collection frame 7 is equipped with filter screen plates 14 that communicate with the cavity on all four sides. The filter screen plates 14 are made of stainless steel filter screen, which can effectively filter impurities in nitrogen gas and prevent dust from escaping from the top of the collection frame 7, further improving the efficiency and effect of dust collection.

[0026] Spoon shell structure: To prevent dust from falling back into the cavity, multiple spoon shells 9 are installed inside the cavity. These multiple spoon shells 9 are arranged in multiple rows at equal distances, with each row staggered. The spoon shell 9 adopts a unique structural design, consisting of a bottom spoon plate 901 and an inner spoon part 902. The bottom spoon plate 901 is made of ceramic material, which has good wear resistance and chemical stability, and can withstand the impact and friction of dust, ensuring the service life of the spoon shell. The inner spoon part 902 is made of nylon material, which has high flexibility and static electricity generation characteristics. Through the concave design of the top of the spoon shell 9 and the staggered arrangement of multiple rows at equal distances, the falling dust can be effectively collected and contained, greatly reducing the possibility of dust being re-entrained.

[0027] Attraction Structure: Multiple attraction structures 10 are located at the center of the collection frame 7. Each attraction structure 10 includes a central rod 101 rotatably connected to the collection frame 7. The central rod 101 is made of high-strength alloy steel and is rotatably connected to the collection frame 7 via high-precision bearings to ensure smooth rotation. A propeller 105 is mounted at the bottom of the central rod 101. The propeller 105 is made of lightweight, high-strength carbon fiber composite material, providing excellent aerodynamic performance. When the central rod 101 rotates, the propeller 105 rotates accordingly, generating a powerful airflow that draws dust into the cavity. Multiple connecting posts 102 are fixed to the outer periphery of the central rod 101. The center of each connecting post 102 is made of metal, providing good structural strength, while the outer surface of the connecting posts 102 is made of rubber, which has good insulation and friction properties. The outer periphery of the connecting posts 102 is movably connected... There is an electrostatic ring 103, which is made of rubber. Multiple electrostatic balls 104 are fixed on its outer periphery. One end of the electrostatic ball 104 is spherical, and multiple dust cavities are opened on the spherical surface to collect dust. Both the electrostatic ring 103 and the electrostatic balls 104 are made of rubber. When the central rod 101 rotates, it drives the connecting column 102 to rotate, so that the electrostatic balls 104 come into contact with the inner spoon part 902 and generate friction during the rotation. Due to the frictional characteristics between rubber and nylon, static electricity is generated between the inner spoon part 902 and the rubber material. Combined with the dust cavities of the electrostatic balls 104 and the top depression of the inner spoon part 902, dust can be adsorbed and it is not easy to fall off, thereby realizing the centralized collection of dust. When it is necessary to clean the dust, the operation of the drive motor 113 is stopped, the collection frame 7 is removed, and the static electricity disappears, so the inside of the collection frame 7 can be cleaned easily.

[0028] Drive Structure: To achieve efficient operation of the suction structure 10, a drive structure 11 is provided on the upper part of the collection frame 7. The drive structure 11 includes multiple gears 111. The gears 111 are fixed to the top of the central rod 101 by a key connection to ensure the stability of power transmission. The outer four sides of the drive gear 112 mesh with the gears 111 on the corresponding central rod 101. A drive motor 113 is installed in the center of the drive gear 112. The drive motor 113 is a high-performance AC motor with high power and stable speed. Its bottom is fixed to the top of the collection frame 7 by bolts. Due to the meshing design of multiple gears 111, adjacent central rods 101 will rotate in opposite directions. In order to ensure that multiple propellers 105 can effectively attract dust into the cavity, adjacent propellers 105 are arranged in opposite directions. In this way, no matter the rotation direction of the central rod 101, the propellers 105 can generate airflow to attract dust into the cavity, improving the efficiency and effect of dust collection.

[0029] In humid environments, heating rods can be installed on the top wall of the cavity of collection box 7 to maintain a dry environment and prevent static electricity from being generated.
