[0034] Reference Figure 1 , Figure 4 The mounting device of the embodiment of the utility model includes a mounting head 41, a nozzle assembly 5, a vacuum structure and a vacuum breaking structure. An air passage 42 is provided inside the mounting head 41 to provide a gas passage for vacuuming and vacuum breaking. The nozzle assembly 5 is installed at the end of the mounting head 41 and communicated with one end of the air passage 42 to facilitate the flow of gas.

[0035] The vacuum structure is installed on one side of the mounting head 41, and includes a first vacuum tube 21, a second vacuum tube 23 and a first air filter 22, wherein the first air filter 22 is disposed between the first vacuum tube 21 and the second vacuum tube 23. The vacuum structure is used to provide a vacuum state for the nozzle assembly 5, and to adsorb the filter glass 7 onto the nozzle assembly 5. In actual situations, a solenoid valve is connected to one end of the first vacuum tube 21 away from the first air filter 22 to control and adjust the vacuuming process.

[0036] For example, when a vacuum operation is required, the solenoid valve is opened so that air is drawn out along the second vacuum tube 23, the first air filter 22, and the first vacuum tube 21. At the same time, the drawn air can be filtered through the first air filter 22. The second vacuum tube 23 is connected to the airway 42 at one end away from the first air filter 22. When the vacuum operation is completed, the solenoid valve is closed to continue to maintain the vacuum state. At this time, most of the air stays in the second vacuum tube 23 and has not been filtered by the first air filter 22, and contains impurities. Maintaining the vacuum state inside the vacuum structure and the mounting head 41 can prevent the impure air staying in the second vacuum tube 23 from flowing back to the surface of the optical effective area 71 to cause damage, resulting in product scrapping.

[0037] The vacuum breaking structure is installed on one side of the mounting head 41, and includes a first vacuum breaking tube 31, a second vacuum breaking tube 33 and a second air filter 32, wherein the second air filter 32 is arranged between the first vacuum breaking tube 31 and the second vacuum breaking tube 33. The vacuum breaking structure is used to separate the filter glass 7 from the nozzle assembly 5 and mount the filter glass 7 on the substrate. In actual situations, a solenoid valve is connected to the end of the first vacuum breaking tube 31 away from the second air filter 32 to control and adjust the vacuum breaking process.

[0038] For example, when it is necessary to perform a vacuum tube breaking operation, the solenoid valve is opened so that the air is blown out along the first vacuum tube 31, the second air filter 32, and the second vacuum tube 33. At the same time, all the blown air can be filtered through the second air filter 32. The second vacuum tube 33 is connected to the airway 42 at one end away from the second air filter 32. The filtering of the second air filter 32 can ensure that the air entering the mounting head 41 and the nozzle assembly 5 is clean air. The clean air entering the mounting head 41 carries a certain air pressure, and a part of the clean air enters the second vacuum tube 23, and through the pressure of its air pressure, the unclean gas in the vacuum state in the second vacuum tube 23 is prevented from entering the mounting head 41, polluting the vacuum-breaking gas, and preventing the product from being scrapped due to the unclean vacuum-breaking gas, thereby improving the product yield.

[0039] In some embodiments, the mounting device further includes a pressure control structure 1. The pressure control structure 1 is disposed above the mounting head 41, and the lower portion thereof extends into the mounting head 41. The pressure control structure 1 has a pressure conversion board and a pressure control board, which are used to control the pressure of the mounting head 41, so that the mounting process control is more precise. According to actual conditions, a varistor may be disposed on the mounting head 41, and the varistor may be electrically connected to the pressure conversion board of the pressure control structure 1. The pressure conversion board converts the varistor signal into a voltage and feeds it back to the pressure control board. The pressure control board in turn controls the mounting pressure and mounting time required for the mounting head 41 to be pressed down through the voltage.

[0040] For example, when mounting the filter glass 7 downward, the pressure control board sets the mounting pressure to 1N and the mounting time to 50ms. When the suction nozzle assembly 5 presses the sucked filter glass 7 in contact with the substrate, the pressure conversion board converts the pressure received by the varistor into voltage and feeds it back to the pressure control board. When the pressure reaches 1N, the pressure control board controls the mounting head 41 to stop pressing down. The mounting head 41 stops for 50ms before breaking the vacuum and lifts up the mounting head 41 to separate the filter glass 7 from the suction nozzle assembly 5, completing the mounting of the filter glass 7.

[0041] In some embodiments, reference Figure 2 , a hollow access piece 43 is installed on one side of the mounting head 41, and the access piece 43 is connected to the end of the airway 42 away from the suction nozzle assembly 5, and one side of the access piece 43 is respectively connected to the second vacuum tube 23 and the second vacuum-breaking tube 33, and the mounting head 41 is connected to the second vacuum tube 23 and the second vacuum-breaking tube 33 through the access piece 43. That is, the access piece 43 connects the vacuum structure and the vacuum-breaking structure with the mounting head 41 through the second vacuum tube 23 and the second vacuum-breaking tube 33. When the vacuum pumping operation and the vacuum-breaking operation are performed, the gas flows in the mounting head 41 and the suction nozzle assembly 5 through the access piece 43. Since the internal passages of the airway 42 and the suction nozzle assembly 5 connected thereto are relatively narrow, and during the vacuum pumping process, the gas in the mounting head 41 moves to the side of the second vacuum tube 23 to form a vacuum state, most of the unclean gas is in the second vacuum tube 23. Therefore, the unclean gas staying in the airway 42 and the suction nozzle assembly 5 can be ignored.

[0042] In some embodiments, the nozzle assembly 5 includes a nozzle 51, a contact portion 52, a fixture 53, and a connector 54. The upper end of the nozzle 51 is connected to the fixture 53, and the fixture 53 is used to connect with other structures to fix the nozzle 51. The upper end of the connector 54 is connected to the mounting head 41, and the lower end is connected to the fixture 53, which is used to connect the mounting head 41 with the nozzle 51. However, it should be understood that in some embodiments, the nozzle assembly 5 may not include the connector 54. That is, the nozzle assembly 5 may include the nozzle 51, the contact portion 52, and the fixture 53.

[0043] A contact portion 52 is provided at the lower end of the suction nozzle 51. The shape of the contact portion 52 is adapted to the shape of the filter glass 7 and is used to contact the filter glass 7 and cooperate with the mounting head 41 to achieve the suction and mounting of the filter glass 7. The contact portion 52 includes an avoidance groove 55 with a bottom opening. Figure 3 Schematic diagram of the structure of the filter glass 7, the avoidance groove 55 has an area larger than the optically effective area 71 of the filter glass 7 in the horizontal cross section, and is used to avoid the optically effective area 71, so that the contact portion 52 only contacts the ineffective area 72, thereby preventing the optically effective area 71 from being damaged due to the contact of the contact portion 52 to the optically effective area 71.

[0044] In some embodiments, the horizontal cross-sectional shape of the contact portion 52 includes a rectangle, and the horizontal cross-sectional shape of the avoidance groove 55 includes a rectangle, which is used to adapt to the shapes of the ineffective area 72 and the optically effective area 71 to avoid contact between the contact portion 52 and the optically effective area 71 and damage to the optically effective area 71.

[0045] In some embodiments, the first air filter 22 and the second air filter 32 are one-way filters. The one-way filter can better filter the gas in the pipeline separately during vacuuming and breaking the vacuum, and avoid the impurity particles filtered out by the two-way airflow being disturbed by the two-way airflow during bidirectional filtering, thereby polluting the clean gas after filtration. The one-way filter can be used for separate filtering to improve the filtering effect of the first air filter 22 and the second air filter 32 during vacuuming and breaking the vacuum, protect the optical effective area 71 from being affected, and improve the product yield.

[0046] In some embodiments, the mounting device further comprises a mounting frame 61, the upper end surface of which is mounted with the pressure control structure 1, and the lower end surface of which is mounted with the mounting head 41. The mounting frame 61 is used to protect and limit the positions of the pressure control structure 1 and the mounting head 41, so that they become a whole.

[0047] In some embodiments, at least one side plate 62 is connected to the side of the mounting frame 61 for mounting and positioning components disposed on the side of the pressure control structure 1. The first air filter 22 and the second air filter 32 are respectively mounted on at least one side plate 62. According to actual conditions, one side plate 62 may be provided to position the first air filter 22 and the second air filter 32, or multiple side plates 62 may be provided to mount other components, such as positioning a portion of the first vacuum tube 21 and the first vacuum-breaking tube 31, so as to obtain a smoother gas flow effect and improve production efficiency.

[0048] The embodiment of the present application provides a filter glass mounting device, in which the pipelines of the vacuum structure and the vacuum-breaking structure are separately arranged to prevent the unclean gas remaining in the pipeline from being carried out by the vacuum-breaking gas and contaminating the vacuum-breaking gas during vacuuming, so that the unclean vacuum-breaking gas affects the optical effective area of ​​the filter glass. At the same time, the bidirectional air filter is changed into a unidirectional first filter and a second filter, and they are respectively arranged in the vacuum structure and the vacuum-breaking structure, so that the gas in a single air filter flows unidirectionally, which improves the air filtering effect in the pipeline and improves the overall yield.

[0049] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
