[0036] In this embodiment, see Figure 4 and combined Figure 1 and Figure 2 As shown, the first transfer unit 2 includes a first linear drive assembly 21 and a transfer platform 22. The first linear drive assembly 21 is connected to the rack platform 100. A first end of the first linear drive assembly 21 extends below the flipping platform 1, and a second end extends below the second transfer unit 3. The transfer platform 22 is movably connected to the first linear drive assembly 21.

The first end of the second linear drive assembly 31 extends above the first transfer unit 2, and the second end of the second linear drive assembly 31 extends outside the second end of the frame platform 100. The gripping assembly 32 is movably connected to the second linear drive assembly 31 and is configured to grip and move the glass cover plate. The gripping assembly 32 grips the glass cover plate from the first transfer unit 2 and, driven by the second linear drive assembly 31, first sends the glass cover plate to the top of the cleaning unit 4 for dust removal and cleaning, and then sends the glass cover plate to a downstream working device, specifically an automatic bonding device for explosion-proof film and glass cover plate.

[0039] In this embodiment, see Figure 6 and Figure 7 and combined Figure 1 and Figure 2 As shown, the cleaning unit 4 includes an unwinding mechanism 41, a winding mechanism 42, a roller assembly 43, a pressing assembly 44, and a cleaning cloth 45. The cleaning cloth 45 is arranged in a roll within the unwinding mechanism 41. The cleaning cloth 45 is released from the unwinding mechanism 41, tensioned above the roller assembly 43, and then wound back into the winding mechanism 42. The pressing assembly 44 is vertically and vertically positioned below the roller assembly 43. The pressing assembly 44 is configured to press the cleaning cloth 45 upwards against the glass cover plate to clean it. It should be noted that... Figure 6 The cleaning cloth 45 is not shown in the image.

[0040] As described above, the cleaning unit 4 can be configured with the winding mechanism 42 as an active rotating mechanism and the unwinding mechanism 41 as a driven rotating mechanism. During the cleaning process of the glass cover plate, the cleaning cloth 45 is gradually transferred from the unwinding mechanism 41 to the winding mechanism 42. Specifically, when the second transfer unit 3 feeds the glass cover plate above the roller assembly 43, the pressing assembly 44 presses the cleaning cloth 45 upwards onto the lower surface of the glass cover plate. By controlling the lateral movement of the glass cover plate and the transmission of the cleaning cloth 45 from the unwinding mechanism 41 to the winding mechanism 42, the cleaning cloth 45 performs dust removal and cleaning treatment on the lower surface of the glass cover plate (the bonding surface for subsequent bonding processes) by wiping.

[0041] In the cleaning unit 4, a first guide roller group 46 is arranged between the unwinding mechanism 41 and the idler roller assembly 43 along the transmission path of the cleaning cloth 45, and a second guide roller group 47 is arranged between the idler roller assembly 43 and the winding mechanism 42. The cleaning cloth 45 released from the unwinding mechanism 41 is connected to the idler roller assembly 43 through the first guide roller group 46, and then connected to the winding mechanism 43 through the second guide roller group 47.

[0042] In a preferred embodiment, the idler assembly 43 includes a first idler 431, a second idler 432, a third idler 433, and a fourth idler 434 arranged sequentially on a first horizontal plane, and also includes a tension roller 435 located below the first horizontal plane and between the second idler 432 and the third idler 433.

The tension roller 435 is used to adjust the tension of the cleaning cloth 45 so that the cleaning cloth 45 is tautly connected to the first idler 431, the second idler 432, the third idler 433, and the fourth idler 434.

[0043] Furthermore, below the first horizontal plane, a top-pressing assembly 44 is respectively provided between the first idler roller 431 and the second idler roller 432, and between the third idler roller 433 and the fourth idler roller 434. Thus, the cleaning unit 4 can perform two separate cleaning processes on the lower surface of the glass cover, achieving a better cleaning effect.

[0044] The top-pressing assembly 44 includes a lifting drive module 441 and a top-pressing structural member 442. The top-pressing structural member 442 is vertically and flexibly connected to the output end of the lifting drive module 441 on the side facing the cleaning cloth 45. The top-pressing structural member 442 is an elongated plate extending along the width direction of the cleaning cloth 45.

[0045] Furthermore, the cleaning unit 4 also includes a cleaning agent spraying mechanism 48 disposed below the idler roller assembly 43 and located on the side of the top pressing assembly 44. The cleaning agent spraying mechanism 48 is used to spray cleaning agent onto the cleaning cloth 45 to further improve the cleaning effect.

[0046] In summary, the glass cover plate feeding device provided in this utility model embodiment can automatically feed the glass cover plate to the downstream explosion-proof film and glass cover plate automatic bonding equipment, and can perform dust removal and cleaning treatment on the bonding surface of the glass cover plate during the feeding process to ensure that the glass cover plate can be firmly bonded to the explosion-proof film in the subsequent bonding process.

[0047] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
