[0002] In the manufacturing process of the display device, refer to Figure 1 As shown, for some processes and procedures, the glass substrate 1' needs to be flipped. However, during the flipping process of the glass substrate 1', it is necessary to avoid damage to the glass substrate 1' as much as possible. In the prior art, the glass substrate 1' is first placed flat on the flip bracket of the flip mechanism, and the glass substrate 1' is flipped by flipping the flip bracket to achieve the flipping operation of the glass substrate 1'. However, during the flipping process of the glass substrate 1'. In order to reduce damage to the glass substrate 1', the fixed clamp 2' of the clamping assembly for clamping the glass substrate 1' does not completely clamp the glass substrate 1', and a certain clamping gap 3' is left between the edge of the glass substrate 1' and the fixed clamp 2'. As a result, the glass substrate 1′ still moves toward the corresponding gap under the action of gravity during the flipping process, so that the fixing clamp 2′ scratches the surface of the glass substrate. At the same time, due to the displacement or shaking of the glass substrate 1′ during the flipping process, the support column 4′ on the flip bracket for supporting the glass substrate 1′ may also scratch the surface of the glass substrate 1′, affecting the quality of the glass substrate 1′ and the subsequent production quality of the display device.

[0032] The advantages and features of the present invention and the methods for achieving them will become apparent with reference to the embodiments described in detail below in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various forms. The present embodiments are provided only to complete the disclosure of the present invention and to enable those skilled in the art to fully understand the scope of the present invention, and the present invention is limited only by the scope of the claims. The same reference numerals represent the same constituent elements throughout the specification.
[0033] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
[0034] like Figures 2 to 9As shown, a glass substrate flipping device of the present embodiment comprises a flipping mechanism 2 and a clamping assembly 3. The flipping mechanism 2 comprises a flipping base 21 and a flipping bracket 22. The flipping bracket 22 is rotatably arranged on the flipping base 21. A side of the flipping bracket 22 for supporting a glass substrate 1 is provided with a plurality of supporting columns 221. The clamping assembly 3 is placed on the flipping bracket 22 for clamping the glass substrate 1. The clamping assembly 3 comprises a clamping bottom plate 31. A plurality of fixing clamps 32 for clamping the edge of the glass substrate 1 are provided on the clamping bottom plate 31. The clamping assembly 3 also comprises a pneumatic assembly 4. The pneumatic assembly 4 is arranged on the flipping bracket 22. The pneumatic assembly 4 comprises a plurality of air nozzle components. The air nozzle components comprise a first air nozzle 41 arranged on a side plate surface with an air port facing the glass substrate 1. The first air nozzle 41 and the supporting column 221 are arranged on the same side of the flipping bracket 22 to cooperate with the supporting column 221 to achieve the function of supporting or adsorbing and fixing the glass substrate 1.
[0035] In this embodiment, during the glass substrate 1 flipping operation, the glass substrate 1 is first placed on the flip bracket 22 together with the clamping assembly 3 for clamping and fixing the glass substrate 1 through an external loading device. Among them, because the fixing clamp 32 on the clamping assembly 3 only clamps the edge of the glass substrate 1, when the glass substrate 1 is placed on the flip bracket 22, a plurality of support columns 221 are provided on the flip bracket 22 for providing a certain support to the middle position of the glass substrate 1, so as to prevent the deformation of the glass substrate 1 and wrinkles on the coating on the surface of the glass substrate 1, thereby affecting the quality of the glass substrate 1 and subsequent processing.
[0036] Furthermore, the device further includes a pneumatic component 4, which is arranged on the flip bracket 22, and a plurality of first air nozzles 41 of the pneumatic component 4 are arranged toward one side of the glass substrate 1, so as to blow or inhale air to one side of the glass substrate 1. Specifically, first, when the glass substrate 1 is placed flat on the flip bracket 22, the first air nozzle 41 blows air from bottom to top toward one side of the glass substrate 1, so as to apply a certain vertical upward buoyancy to the glass substrate 1, so as to reduce the collision between the glass substrate 1 and the support column 221 on the flip bracket 22 during the process of feeding the glass substrate 1 to the flip bracket 22. Moreover, by continuously blowing air to the glass substrate 1 through the first air nozzle 41, the pressure of the support column 221 on the flat glass substrate 1 can be reduced, and the damage caused by the support column 221 to the glass substrate 1 and the possibility of causing damage can be reduced, which is conducive to improving the processing quality of the glass substrate 1.
[0037] Secondly, when the flip bracket 22 drives the glass substrate 1 to flip, the first air nozzle 41 is changed to suck air toward one side of the glass substrate 1 to achieve adsorption and fixation of the glass substrate 1, which can effectively prevent the glass substrate 1 from shaking during the flipping process and prevent displacement between the glass substrate 1 and the clamping assembly 3, thereby preventing the glass substrate 1 from colliding and scratching with the clamping assembly 3 or the flip bracket 22, which is beneficial to ensuring the stability of the flipping operation of the glass substrate 1 and ensuring the processing quality of the glass substrate 1.
[0038] In one embodiment, the pneumatic assembly 4 further includes a pneumatic element (not shown), which is disposed on the flip base 21 or the flip bracket 22 and is connected to the first air nozzle 41 through the air delivery pipe 42 to inhale or blow air toward the air port. In actual operation, the pneumatic element is configured as a double-acting cylinder or a double-acting air pump to realize the driving control of the first air nozzle 41 in two modes: blowing and inhaling.
[0039] In one embodiment, the gas delivery pipeline 42 is fixed on the flip bracket 22, and the flip bracket 22 includes a plurality of transverse plates 222 and vertical plates 223 connected at an angle to each other, and a gas delivery gap 224 for the first gas nozzle 41 to pass through is formed between the plurality of transverse plates 222 and vertical plates 223. In actual operation, the flip bracket 22 is provided with a plurality of gas delivery pipelines 42, which are respectively fixed on the transverse plates 222 and vertical plates 223, and a plurality of first gas nozzles 41 are arranged in each gas delivery gap 224 region between the transverse plates 222 and the transverse plates 222, between the transverse plates 222 and the vertical plates 223, and between the vertical plates 223 and the vertical plates 223, so that the first gas nozzle 41 can pass through the gas delivery gap 224 to achieve the effect of adsorption or blowing support for the glass substrate 1 placed on the flip bracket 22.
[0040] In one embodiment, the air nozzle component further includes a plurality of second air nozzles 43, and the air outlet direction of the second air nozzle 43 is arranged opposite to the air outlet direction of the first air nozzle 41, that is, the second air nozzle 43 is arranged in the direction of the flip base 21. Since the present device is applied to the processing field of display devices, and involves direct contact with the glass substrate 1, the core component of the display device, in the field of display device processing, the plate surface of the glass substrate 1 needs to be kept extremely clean and intact. Therefore, it is very important to keep the equipment clean, and in this embodiment, when the present device does not perform the glass substrate 1 flipping operation, the second air nozzle 43 can be used to blow air toward the flip base 21 to achieve the effect of dust blowing and dust removal. In addition, by flipping and rotating the flip bracket 22, the blowing angle of the second air nozzle 43 can be adjusted to blow and dust at various angles of the flip base 21, which is conducive to maintaining the cleanliness of the equipment and avoiding contamination of the glass substrate 1 when the glass substrate 1 is flipped.
[0041] In actual operation, the second air nozzle 43 can be arranged in a direction around the air delivery pipe 42 toward other directions, that is, the second air nozzle 43 and the first air nozzle 41 are arranged at other angles, such as the second air nozzle 43 and the first air nozzle 41 are arranged at angles of 90°, 135°, 150°, etc., so as to perform air blowing and dust removal on the flip mechanism 2 at various angles through the second air nozzle 43. For the present utility model, the angle between the first air nozzle 41 and the second air nozzle 43 is not limited to the various angles of the above-mentioned embodiments, nor is it limited to being arranged in opposite directions. As long as the second air nozzle 43 can be used to blow and dust the flip mechanism 2, such a design belongs to the protection scope of the present utility model.
[0042] In one embodiment, the second air nozzle 43 includes an air outlet pipe 431, and a plurality of auxiliary air holes 432 are provided on the side wall of the air outlet pipe 431 to further assist the second air nozzle 43 in blowing and cleaning the flip base 21. Furthermore, the auxiliary air holes 432 can realize blowing at various angles different from the blowing angle of the second air nozzle 43, which can further improve the cleaning effect.
[0043] Furthermore, a plurality of auxiliary air holes 432 are evenly distributed around the central axis of the air outlet pipe 431 to ensure that the airflow of the air is evenly and directionally output. Moreover, the auxiliary air holes 432 are provided in a plurality of groups, and the plurality of groups of auxiliary air holes 432 are sequentially arranged side by side along the central axis direction of the air outlet pipe 431 to increase the air output of the auxiliary air holes 432 and improve the cleaning effect.
[0044] In one embodiment, the glass substrate flipping device further includes a telescopic positioning assembly 5, which is arranged on the flip bracket 22, and the telescopic positioning assembly 5 includes a plurality of telescopic rods 51 and a telescopic driving member 52 that is transmission-connected to the telescopic rods 51, and a plurality of positioning holes 311 for the telescopic rods 51 to pass through are provided on the clamping base plate 31. Specifically, when the clamping base plate 31 clamps the glass substrate 1 and places it horizontally on the flip bracket 22, the plurality of positioning holes 311 on the clamping base plate 31 correspond to the plurality of telescopic rods 51 one by one, and the telescopic rods 51 are driven by the telescopic driving member 52 to extend through the positioning holes 311, so as to realize the positioning and fixing of the clamping base plate 31 and the flip bracket 22. In addition, when the flip bracket 22 drives the clamping base plate 31 to flip to a vertical state, the connection and fixing of the clamping base plate 31 and the flip bracket 22 can be maintained, and after the flip is completed, the telescopic driving member 52 drives the telescopic rods 51 to retract and leave the positioning holes 311, so that the clamping base plate 31 is transported to the next process.
[0045] In actual operation, the telescopic drive member 52 is set as a driving device such as a telescopic cylinder or a telescopic linear motor. No specific limitation is made in this embodiment. As long as it can drive the telescopic rod 51 to telescopically move to achieve the positioning and fixation of the clamping base plate 31, such designs belong to the protection scope of the present utility model.
[0046] In one embodiment, the glass substrate flipping device further includes a conveying assembly 6, which includes a conveying track 61 disposed on the base. When the flip bracket 22 flips the clamping base plate 31 to a vertical state, the clamping base plate 31 is located directly above the conveying track 61, and then the clamping base plate 31 and the glass substrate 1 clamped and fixed on the clamping base plate 31 are conveyed to the next process through the conveying track 61. A conveying driving member 62 is disposed on one side of the conveying track 61, and the conveying driving member 62 is driven to realize the conveying of the clamping base plate 31 and the glass substrate 1 disposed on the conveying track 61.
[0047] In one embodiment, the conveying assembly 6 further includes a positioning sensor 63, and a sensing component 225 for sensing by the positioning sensor 63 is provided on the flip bracket 22. When the sensing component is located within the sensing range of the positioning sensor 63, the clamping bottom plate 31 is located directly above the conveying track 61. The sensor is used to determine whether the flip bracket 22 is flipped in place, so as to avoid the flip bracket 22 not being flipped in place, resulting in the clamping bottom plate 31 not being able to be firmly placed on the conveying track 61 to complete the conveying, thereby causing the glass substrate 1 to be separated from the conveying track 61 and damaged.
[0048] In one of the embodiments, the conveying track 61 is configured as a magnetic levitation track, and conveying is performed via the magnetic levitation track, thereby avoiding direct contact conveying, so as to prevent the clamping base plate 31 from colliding with the conveying track 61 when being flipped and placed on the conveying track 61, thereby reducing the possibility of the glass substrate 1 being subjected to collision vibration and damage, which is beneficial to ensuring the stability of the flipping of the glass substrate 1.
[0049] In one embodiment, a limiting support rod is provided on the flip bracket 22, and a limiting support for cooperating with the limiting rod to limit the flip angle of the flip bracket 22 is provided on the flip base 21. Specifically, the limiting support includes a horizontal limiting frame 211 and a vertical limiting frame 212, and the flip bracket 22 includes a horizontal limiting rod 226 and a vertical limiting rod 227 respectively arranged corresponding to the horizontal limiting frame 211 and the vertical limiting frame 212. Among them, the horizontal limiting frame 211 is located within the rotation track range of the horizontal limiting rod 226, and the vertical limiting frame 212 is located within the rotation track range of the vertical limiting rod 227. Therefore, when the glass substrate 1 is horizontally placed on the flip bracket 22, the horizontal limiting rod 226 abuts against the horizontal limiting frame 211 to limit the rotation of the horizontal limiting rod 226 through the horizontal limiting frame 211, and at this time, the flip surface of the flip bracket 22 for placing the glass substrate 1 is parallel to the horizontal plane. Similarly, when the flip bracket 22 flips the glass substrate 1 to a vertical state, the vertical limit rod 227 abuts against the vertical limit frame 212 to limit the rotation of the vertical limit rod 227 through the vertical limit frame 212. At this time, the flip bracket 22 is used to place the flip surface of the glass substrate 1 parallel to the vertical plane.
[0050] Although the embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above embodiments, but can be manufactured in various forms, and those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical spirit or basic features of the present invention. Therefore, it should be understood that the above embodiments are exemplary and not restrictive in all aspects.
