Description

Technical Field

[0001] This utility model relates to the field of photovoltaic glass laser mold removal technology, specifically a dust removal device for photovoltaic glass laser mold removal. Background Technology

[0002] During the laser removal of mold from photovoltaic glass, a large amount of submicron-sized mixed powder is generated when the high-energy laser beam vaporizes the mold spots. Its main components are mold cell wall fragments and anti-mold powder residue. If it is not removed in time, these electrostatically charged dust particles will re-settle on the photovoltaic glass, forming a light-blocking shadow area, thereby affecting the light transmittance of the photovoltaic glass.

[0003] Currently, the dust removal method used in the laser mold removal production line for photovoltaic glass is an open negative pressure method. Specifically, a dust suction hood is installed above the conveyor roller to perform negative pressure dust suction. When the photovoltaic glass passes through the dust suction hood, the dust is extracted. However, this method has poor sealing and is prone to dust leakage. Moreover, the distance between the dust suction port and the glass surface is relatively far (generally more than 100mm), resulting in poor suction effect. Utility Model Content

It adopts an online dust removal method and uses an air seal to dynamically blow and perform close-range negative pressure dust suction on the glass part that moves into the inner cavity of the sealed cover.

[0017] 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.

[0018] Please see Figure 1-4This utility model provides a technical solution: a dust removal device for laser mold removal on photovoltaic glass, including a sealing cover 1. Both ends of the sealing cover 1 are provided with ventilation grooves, and both ends of the inner side of the sealing cover 1 are provided with uniformly distributed air jet holes 3. The upper and lower end faces of the middle of the inner side of the sealing cover 1 are provided with uniformly distributed dust suction holes 2, and the middle of the sealing cover 1 corresponding to the dust suction holes 2 is provided with a dust suction chamber connecting all the dust suction holes 2. Two symmetrically arranged blowing pipes 4 are rotatably arranged inside the upper end of the sealing cover 1. The bottom of the blowing pipes 4 is provided with uniformly distributed blowing holes 41, and the side of the sealing cover 1 is provided with a driver to drive the blowing pipes 4 to rotate. The opening of the sealing cover 1 is sealed by air jet holes 3, and then the dust on the sealing cover 1 is extracted by dust suction holes 2 and dust suction pipes 21. The high-pressure gas ejected from the blowing holes 41 blows away the dust attached to the photovoltaic glass, making the dust float up and helping it to be extracted by the dust suction holes 2.

[0019] Furthermore, the sealing cover 1 is provided with a vent pipe 31 that communicates with the vent groove, and the vent pipe is connected to an external high-pressure air pump.

[0020] Furthermore, the sealing cover 1 is provided with a suction pipe 21 that communicates with the suction chamber. The suction pipe 21 is used to connect to an external suction device. The external suction device extracts the dust inside the sealing cover 1 through the suction pipe 21 and the suction hole 2, thereby performing dust removal and cleaning operations on the photovoltaic glass after laser mold removal.

[0021] Furthermore, one end of the purge pipe 4 is provided with a connecting pipe for connecting to an external high-pressure air pump.

[0022] Furthermore, the driver includes a motor 6, a drive plate 7, and a connecting plate 5. The connecting plate 5 is mounted on the blow pipe 4, and both ends of the drive plate 7 are rotatably connected to the two connecting plates 5 respectively. The motor 6 is mounted on the sealing cover 1. A turntable 61 is provided on the output shaft of the motor 6, and an eccentric rod 62 is provided on the turntable 61. A limit hole 71 is opened on the drive plate 7, and the eccentric rod 62 is movably inserted inside the limit hole 71. The motor 6 drives the turntable 61 to rotate. When the turntable 61 drives the eccentric rod 62 to rotate, the eccentric rod 62 drives the drive plate 7 to move. The drive plate 7 drives the blow pipe 4 to reciprocate within a certain range through the connecting plate 5. When the blow pipe 4 rotates, it drives the blow hole 41 to oscillate back and forth within a certain angle, thereby blowing the surface of the photovoltaic glass from different angles and improving the dust removal and cleaning effect of the photovoltaic glass.

[0023] The motor 6 used in this utility model is a commonly used electronic component in the prior art. Its working method and circuit structure are well-known technologies and will not be described in detail here.

[0024] When using:

[0025] The sealing cover 1 is placed between two roller conveyors so that when the roller conveyors transport the mold-free photovoltaic glass, the photovoltaic glass passes through the inside of the sealing cover 1.

[0026] An external high-pressure air pump delivers high-pressure air to the vent pipe 31 and the connecting pipe respectively. The high-pressure air in the vent pipe 31 is ejected through the jet hole 3, thereby sealing the internal space of the sealing cover 1. The high-pressure air inside the purge pipe 4 is ejected through the purge hole 41, thereby purging the surface of the photovoltaic glass.

[0027] The control motor 6 works, and the motor 6 drives the turntable 61 to rotate. When the turntable 61 drives the eccentric rod 62 to rotate, the eccentric rod 62 drives the drive plate 7 to move. The drive plate 7 drives the blowing pipe 4 to reciprocate within a certain range through the connecting plate 5. When the blowing pipe 4 rotates, it drives the blowing hole 41 to swing back and forth within a certain angle, thereby blowing the surface of the photovoltaic glass from different angles and improving the dust removal and cleaning effect of the photovoltaic glass.

[0028] At the same time, the external dust collection device is controlled to work. The external dust collection device extracts the dust inside the sealing cover 1 through the dust collection pipe 21 and the dust collection hole 2, thereby performing dust removal and cleaning operations on the photovoltaic glass after laser mold removal.

[0029] This invention employs an online dust removal method, using an air seal to dynamically blow and perform close-range negative pressure dust suction on the glass portion that moves into the inner cavity of the sealing cover 1, achieving fully enclosed dust removal in the work area. This prevents dust from escaping, improves the dust suction effect, and is easy to use.

Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
