Description

Technical Field

[0001] This utility model relates to the field of spraying technology, specifically to an automatic spraying machine for photovoltaic glass glaze. Background Technology

[0002] Photovoltaic glass is a special type of glass used in the field of solar photovoltaic. It has the characteristics of high light transmittance, high strength, and strong weather resistance. It is an important component of solar panels. It is usually made of ultra-white rolled glass or float glass, and the surface is specially treated to reduce light reflection and increase light transmittance, so that solar cells can more effectively absorb light energy and convert it into electrical energy.

[0003] In the production of photovoltaic glass, in order to improve photoelectric conversion efficiency and the durability of glass, it is often necessary to coat the glass surface with a special glaze. This glaze can not only reduce light reflection and improve light absorption rate, but also enhance the corrosion resistance and wear resistance of glass. However, the traditional manual coating method is not only inefficient, but also difficult to guarantee the uniformity and precision of coating. Therefore, the automatic photovoltaic glass glaze spraying machine has emerged. The automatic photovoltaic glass glaze spraying machine is a highly automated device that can spray glaze evenly and quickly on the surface of photovoltaic glass by precisely controlling the movement trajectory of the spray gun and the flow rate of the glaze.

[0004] However, existing automatic photovoltaic glass enamel spraying machines generally use roller conveyors to move the photovoltaic glass into the machine. With increasing usage time, the rollers on the conveyors inside the machine inevitably accumulate enamel. This enamel buildup becomes increasingly thick, making the roller surface rough and uneven, thus affecting the friction between the rollers and the photovoltaic glass. This can lead to the photovoltaic glass shaking, tilting, or even jamming during transport. In severe cases, the photovoltaic glass may even impact the inner wall of the conveyor, causing damage and reducing production efficiency. Therefore, this method does not meet the current requirements. To address this, we propose an automatic photovoltaic glass enamel spraying machine. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic photovoltaic glass glaze spraying machine to solve the problems mentioned in the background art. Existing automatic photovoltaic glass glaze spraying machines generally use roller conveyors to move photovoltaic glass into the machine. With increasing usage time, the rollers on the conveyor inside the machine inevitably accumulate glaze. As the glaze thickens, the roller surface becomes rough and uneven, affecting the friction between the rollers and the photovoltaic glass. This can lead to vibration, tilting, or even jamming of the photovoltaic glass during transport. In severe cases, the photovoltaic glass may even impact the inner wall of the roller conveyor, causing damage and reducing production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic photovoltaic glass glaze spraying machine, comprising a glass spraying machine body, wherein a photovoltaic glass transmission roller conveyor is provided inside the glass spraying machine body, and multiple rollers are fixedly installed inside the photovoltaic glass transmission roller conveyor;

[0007] A stepper motor is fixedly installed on one side of the housing of the photovoltaic glass transmission roller conveyor located inside the main body of the glass spraying machine.

An internal threaded sleeve is installed on one side of the outer surface of the threaded rod through a threaded structure. A connecting plate is fixed to the upper end face of the internal threaded sleeve. Multiple connecting rods are fixedly connected to the upper end face of the connecting plate. A glaze scraping sleeve is fixedly connected to the upper end face of the connecting rod. Multiple glaze scraping sleeves are movably sleeved on the outer surface of the roller located inside the main body of the glass spraying machine, and both sides of the outer surface of the glaze scraping sleeve are shovel-shaped surfaces.

[0008] Preferably, a guide rod is provided below the threaded rod, one side of the outer surface of the guide rod is movably sleeved on the guide sleeve, and the upper end face of the guide sleeve is fixed to the lower end face of the inner threaded sleeve.

[0009] Preferably, a partition is provided above the threaded rod, and the outer surface of the partition is provided with a plurality of strip-shaped through holes.

[0010] Preferably, the outer surface of the connecting rod is in contact with the inner wall of the strip-shaped through hole, and the connecting rod and the strip-shaped through hole are slidably connected.

[0011] Preferably, the threaded rod is located directly below the partition plate, and the positions of the plurality of strip-shaped through holes are all staggered from the threaded rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model enables a stepper motor to drive a glaze scraping sleeve, which is fitted inside the main body of the glass spraying machine, to move back and forth along the outer surface of the roller after the daily work is completed. As the glaze scraping sleeve moves, it will automatically scrape off the glaze adhering to the outer surface of the roller.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] The glass spraying machine body 1 (model jh-01), stepper motor 6 (model DM542), and partition 12 (model FWB-1008) mentioned in this utility model can be obtained from the market or through private customization.

[0026] Please see Figures 1 to 5 An embodiment of this utility model is provided: an automatic photovoltaic glass glaze spraying machine, including a glass spraying machine body 1, a photovoltaic glass transmission roller conveyor 2 is provided inside the glass spraying machine body 1, and multiple rollers 3 are fixedly installed inside the photovoltaic glass transmission roller conveyor 2.

[0027] A stepper motor 6 is fixedly installed on one side of the housing of the photovoltaic glass transmission roller conveyor 2 located inside the main body 1 of the glass spraying machine. The output shaft of the stepper motor 6 is connected to a threaded rod 7 via a coupling. An internal threaded sleeve 8 is installed on one side of the outer surface of the threaded rod 7 via a threaded structure. A connecting plate 16 is fixedly fixed to the upper end face of the internal threaded sleeve 8. Multiple connecting rods 11 are fixedly connected to the upper end face of the connecting plate 16. A glaze scraping sleeve 4 is fixedly connected to the upper end face of the connecting rod 11. Multiple glaze scraping sleeves 4 are movably sleeved on the outer surface of the roller 3 located inside the main body 1 of the glass spraying machine, and both sides of the outer surface of the glaze scraping sleeve 4 are shovel-shaped surfaces 15. A control panel 14 is fixedly installed on one side of the outer surface of the main body 1 of the glass spraying machine, and the main body 1 of the glass spraying machine, the photovoltaic glass transmission roller conveyor 2, and the stepper motor 6 are all electrically connected to the control panel 14. The control panel 14 can control the main body 1 of the glass spraying machine, the photovoltaic glass transmission roller conveyor 2, and the stepper motor 6.

[0028] When the equipment is needed, the photovoltaic glass to be sprayed is placed on the upper end of the photovoltaic glass transmission roller conveyor 2, and then transported to the interior of the glass spraying machine body 1 by the photovoltaic glass transmission roller conveyor 2. After the photovoltaic glass enters the interior of the glass spraying machine body 1, it can be sprayed with glaze by the glass spraying machine body 1.

[0029] When the workday ends, start the stepper motor 6, which will drive the connected threaded rod 7 to rotate.

[0030] A guide rod 9 is provided below the threaded rod 7. One side of the outer surface of the guide rod 9 is movably sleeved on the guide sleeve 10, and the upper end face of the guide sleeve 10 is fixed to the lower end face of the inner threaded sleeve 8. Since the inner threaded sleeve 8, which is installed on the outer surface of the threaded rod 7 through a threaded structure, is fixed to the guide sleeve 10, which is movably sleeved on the outer surface of the guide rod 9, the inner threaded sleeve 8 cannot rotate on its own.

[0031] When the threaded rod 7 rotates, the internal threaded sleeve 8, which is threaded to it but cannot rotate on its own, will move along the outer surface of the threaded rod 7 under the drive of the threaded structure. During the movement of the internal threaded sleeve 8, the glaze scraping sleeve 4, which is connected to it through the connecting plate 16 and multiple connecting rods 11, will move along the outer surface of the roller 3. During the movement of the glaze scraping sleeve 4 on the outer surface of the roller 3, it can scrape off the glaze sprayed on the outer surface of the roller 3 during the operation of the glass spraying machine body 1 through the shovel-shaped surface 15 located on its outer surface. Through the above technical solution, the glaze adhering to the outer surface of the roller 3 can be automatically cleaned, thereby preventing the transmission effect of the roller 3 from being affected by the glaze adhering to its outer surface, ensuring the stability of the equipment during long-term operation, and preventing damage to the photovoltaic glass during transportation.

[0032] A partition plate 12 is provided above the threaded rod 7. The outer surface of the partition plate 12 has multiple strip-shaped through holes 13. The number and position of the multiple strip-shaped through holes 13 correspond to the number and position of the multiple connecting rods 11, and the multiple connecting rods 11 vertically pass through the multiple strip-shaped through holes 13. The outer surface of the connecting rod 11 is in contact with the inner wall of the strip-shaped through hole 13, and the connecting rod 11 and the strip-shaped through hole 13 are slidably connected. The threaded rod 7 is located directly below the partition plate 12, and the positions of the multiple strip-shaped through holes 13 are all staggered from the threaded rod 7. The partition plate 12 located between the roller 3 and the threaded rod 7 can isolate the roller 3 from the threaded rod 7. The partition plate 12 in the above technical solution can prevent the glaze sprayed by the glass spraying machine body 1 from contacting the threaded rod 7 during operation, thereby preventing the external thread structure of the threaded rod 7 from being affected and the internal thread sleeve 8 from moving on the outer surface of the threaded rod 7.

[0033] The glaze scraping sleeve 4 has a receiving groove 5 on one side located on the outer surface of the photovoltaic glass transmission roller conveyor 2, and the receiving groove 5 is larger than the glaze scraping sleeve 4; when the glass spraying machine body 1 is working, the glaze scraping sleeve 4 is moved into the receiving groove 5. Through the above technical solution, it is possible to prevent the photovoltaic glass moving on the roller 3 from contacting the glaze scraping sleeve 4 and causing damage to itself.

[0034] A protective cover plate is provided behind the stepper motor 6 on the outer surface of the photovoltaic glass transmission roller conveyor 2, and the photovoltaic glass transmission roller conveyor 2 is fixed to the protective cover plate by screws; the protective cover plate can seal and protect the stepper motor 6.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
