The movement direction of the glass substrate is defined as a first direction, and the axial direction of the rotation shaft 21 is parallel to the first direction. The air flotation assembly 5 is provided on the flip base 3 and below the glass substrate, and is used to float the glass substrate on the flip base 3. The first servo drive assembly 2 is used to drive the flip base 3, the two sets of conveying assemblies 4, the air flotation assembly 5, and the glass substrate to flip by a preset angle via the rotation shaft 21.

[0080] Optionally, the first servo drive assembly 2 includes a first servo motor and a first seat bearing 22. The first seat bearing 22 is fixed on the bottom support base 1.

[0089] Please refer to Figure 3, as another specific embodiment of the above-mentioned compatible component 6, the compatible component 6 includes a fixed rack 61, a rotating gear box 62 and a rotating drive component 64; the fixed rack 61 is arranged on the flip seat 3 and extends along the second direction; the rotating gear box 62 is arranged on the fixed rack 61, and the driven end of the rotating gear box 62 is engaged with the fixed rack 61 for transmission; a first mounting seat 63 is provided on the top of the rotating gear box 62, and the first mounting seat 63 is used to connect the conveying component 4; the power output end of the rotating drive component 64 is connected to the active end of the rotating gear box 62; wherein, the rotating drive component 64 drives the rotating gear box 62 to engage with the fixed rack 61 for transmission, so as to drive the conveying component 4 connected to the first mounting seat 63 to move along the second direction.

[0090] Optionally, the rotating drive assembly 64 includes a rotating motor, which engages with the fixed rack 61 through the rotating gear box 62, so that the rotating gear box 62 drives the rotating motor and the first mounting seat 63 to move along the extension direction of the fixed rack 61, thereby realizing the movement of the first mounting seat 63 along the second direction, thereby changing the movement of the conveying assembly 4 located on the first mounting seat 63 along the second direction to adjust the distance between the two groups of conveying assemblies 4.

[0091] It should be understood that the rotating gearbox 62 is provided with a first gear set for engaging with the power output end of the rotating motor for transmission, a second gear set for speed regulation, and a rotating gear for engaging with the fixed rack 61 for transmission, and the specific setting method and working principle of the rotating gearbox 62 belong to the existing technology and will not be repeated here.

[0092] Please refer to Figure 3. For example, two groups of fixed racks 61 are arranged at intervals along the first direction, and each group of fixed racks 61 is correspondingly engaged with a rotating gear box 62, and an extended coupling 65 is provided between two adjacent rotating gear boxes 62; a first mounting seat 63 is provided on the top of each rotating gear box 62, and the two first mounting seats 63 are respectively connected to the conveying component 4.

[0093] By arranging two sets of fixed racks 61 at intervals at the second end 312, two sets of first mounting seats 63 are correspondingly arranged, thereby facilitating the installation of the conveying component 4; further, by arranging an extended coupling 65, the two rotating gear boxes 62 are connected in power, thereby ensuring the consistency and smoothness of the movement of the two rotating gear boxes 62, thereby improving the consistency and smoothness of the movement of the conveying component 4.

[0094] Please refer to Figure 3. In some possible embodiments, the flip seat 3 includes two groups of flip plates 31, a counterweight rod 32 and two groups of second mounting seats 33; the two groups of flip plates 31 are arranged at intervals along the first direction; each group of flip plates 31 is correspondingly provided with a connecting flange 34; wherein the rotating shaft 21 is passed through and fixed between the two connecting flanges 34; the counterweight rod 32 is connected between the two flip plates 31 and is close to the rotating shaft 21; the two groups of second mounting seats 33 are respectively arranged on the two flip plates 31; the two second mounting seats 33 are both close to the counterweight rod 32, and the two second mounting seats 33 are connected to one group of conveying components 4.

[0095] It should be understood that since two sets of flip plates 31 are provided in parallel and spaced apart in the present application, the ends of the two sets of flip plates 31 close to the rotating shaft 21 jointly form the first end 311 of the above-mentioned flip seat 3, and the ends of the two sets of flip plates 31 away from the rotating shaft 21 jointly form the second end 312 of the above-mentioned flip seat 3.

[0096] Among them, the rotating shaft 21 is arranged between the two groups of flip plates 31 along the spacing direction of the two groups of flip plates 31, and is connected to the flip plates 31 through a connecting flange 34. The counterweight rod 32 is used to ensure that the first end 311 and the second end 312 of the flip plate 31 are relatively parallel and stable during flipping; the second mounting seat 33 is used to facilitate the installation of the conveying component 4.

[0097] Please refer to Figures 1 to 3. For example, a drag chain assembly 7 is further provided between the flip seat 3 and the support seat 1.

The drag chain support plate 72 is connected between the two flip plates 31 and is located below the rotating shaft 21. The two ends of the drag chain support plate 72 are respectively connected to the extended ends of the two groups of drag chains 71. When the flip seat 3 drives the glass substrate to flip, the drag chain support plate 72 drives the extended ends of the two groups of drag chains 71 to move upward and causes the drag chains 71 to slide on the support seat 1.

[0098] By setting the drag chain assembly 7, when the turning seat 3 turns over, the lower end of the drag chain 71 slides on the support seat 1, so as to properly buffer the turning seat 3 through sliding friction to avoid excessive turning speed.

[0099] Specifically, the drag chain assembly 7 also includes a drag chain mounting frame, and the interior of the drag chain mounting frame is also provided with some lines and air paths for connection, which can avoid damage to the air paths and lines.

[0100] Furthermore, buffers are provided at the front and rear positions of the support base 1 along the second direction corresponding to the flip plate 31 , so as to provide timely buffering and limiting when the flip base 3 flips into place.

[0102] Compressed air is introduced into the micro-pores through the compressed air circuit assembly 54 to float the glass substrate above the air floatation guide rail 51. The glass substrate is adsorbed through the vacuum gap 511 to ensure that the glass substrate floats at a specified position above the air floatation guide rail 51, thereby achieving the floating and position limiting of the glass substrate, preventing the middle effective area of ​​the glass substrate from being damaged during transportation, and thus protecting the glass substrate.

[0103] It should be understood that, considering the small size of the micro pores, they are not shown in the drawings.

Specifically, the second servo drive assembly 42 drives the first transmission shaft 411 to rotate through the belt transmission assembly 421. The magnetic wheel 431 can include two groups, namely the first magnetic wheel 431 and the second magnetic wheel 431. For example, the first transmission shaft 411 is provided with multiple first magnetic wheels 431 at intervals, and each roller shaft 43 is provided with a second magnetic wheel 431.
