Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning machine transfer platform and a cleaning machine. Background Technology
[0002] When a glass washing machine grinds glass, it first grinds the CF (Cross-Face) surface. After CF surface grinding, the glass substrate is transported to a transfer platform. This platform then transfers the substrate to the TFT (Thin-Folded TFT) grinding mechanism, where the TFT surface is ground. During this process, water used in the grinding process remains on the substrate surface after CF surface grinding. This residual water is carried to the transfer platform as the substrate moves. When the glass substrate contacts the transfer platform, the residual water fills the space between them. The more water and the larger the contact area, the stronger the adhesion between them. This adhesion problem is particularly pronounced when processing glass substrates larger than 15 inches, potentially preventing the TFT grinding mechanism from properly removing the substrate and triggering a machine alarm.
[0003] To address this issue, the industry's main approach is to adjust the vacuum breaking and blowing time of the transfer platform, extending it from the original 0.5 seconds to 3 seconds. By extending the vacuum breaking time, the blowing duration of the transfer platform is correspondingly increased. This effectively removes residual water between the glass substrate and the transfer platform, reducing the water's contact area and intermolecular adhesion. Furthermore, the continuous blowing applies an upward force to the glass substrate, assisting the TFT polishing mechanism in more easily removing the substrate, thus mitigating the vacuum abnormality problem to some extent.
[0004] However, even if the current solutions can temporarily alleviate vacuum abnormalities, their inherent shortcomings cannot be ignored from a long-term production and efficiency optimization perspective. These shortcomings may even bring new production challenges. First, this measure cannot fundamentally solve the problem of water accumulation on the transfer platform: extending the blowing time can only blow away some of the moisture in the contact area between the glass substrate and the platform. Water that gradually accumulates in other areas of the transfer platform or during long-term operation remains difficult to drain and thoroughly clean. As operation time progresses, the accumulated water may again alter the contact state between the glass substrate and the platform, increasing the risk of adsorption abnormalities. Second, the extended vacuum breaking time directly negatively impacts the machine's cycle time. In industrial production, cycle time is a key indicator of production efficiency. Increased vacuum breaking time directly leads to a longer overall processing cycle for a single glass substrate, thereby reducing the glass grinding output per unit time. Especially in large-scale mass production scenarios, this decrease in production efficiency directly affects the progress of the overall production plan, adversely impacting the achievement of capacity targets. Utility Model Content
[0005] The purpose of this utility model is to provide a transfer platform and a cleaning machine for a cleaning machine, which improves the problem of water accumulation on the transfer platform, shortens the production cycle time of the machine, and has high production efficiency.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] On one hand, a cleaning machine transfer platform is provided, which is used to carry glass substrates. The cleaning machine transfer platform includes a first base part and a second base part. The first base part includes a first bearing plane on the side facing the glass substrate along a first direction. A plurality of air suction holes are provided on the first bearing plane at intervals along a second direction. The second base part includes an inclined first guide surface on the side facing the glass substrate along the first direction. The first base part and the second base part are alternately arranged along a third direction.
[0008] Optionally, the first guide surface includes a first high end located at the center of the second base portion and a first low end located at one end of the second base portion along the second direction. The second base portion also includes a second guide surface. The second guide surface is inclined and includes a second high end located at the center of the second base portion and a second low end located at the other end of the second base portion along the second direction. The first high end coincides with the second high end.
[0009] Optionally, a transition fillet is provided at the junction of the first high-position end and the second high-position end.
[0010] Optionally, the distance between the first high end and the first low end along the first direction is H1, and satisfies 2.5mm≤H1≤3.5mm;
[0011] And / or, the distance between the second high end and the second low end along the first direction is H2, and satisfies 2.5mm≤H2≤3.5mm.
[0012] Optionally, the thickness of the first base portion along the third direction is T1, and satisfies 9mm≤T1≤11mm;
[0013] And / or, the thickness dimension of the second base portion along the third direction is T2, and satisfies 9mm≤T2≤11mm.
[0014] Optionally, a plurality of liquid storage tanks extending along the third direction are provided on the first bearing plane, and the plurality of liquid storage tanks are arranged at equal intervals along the second direction.
[0015] Optionally, the liquid storage tank has a drainage surface on the side facing the glass substrate, and the height of the drainage surface along the first direction gradually decreases from the center of the liquid storage tank toward the direction closer to the second substrate.

[0017] Optionally, the first guide surface includes a first high end located at the center of the second base portion and a first low end located at the end of the second base portion along the second direction.

[0019] The beneficial effects of this utility model are:
[0020] This utility model provides a transfer platform for a cleaning machine. The platform is constructed by a first base portion having a first bearing plane and a second base portion having an inclined first guide surface. The first and second base portions are alternately arranged along a third direction. This reduces the contact area between the transfer platform and the glass substrate, and allows water on the transfer platform to drain through the first guide surface, preventing water accumulation. These two aspects significantly reduce the uncontrollable adsorption force between the glass substrate and the transfer platform. Furthermore, by providing air suction holes on the first bearing plane, controllable suction ensures the glass substrate is stably fixed on the transfer platform. This improves production efficiency by reducing water accumulation on the transfer platform and shortening the machine's cycle time, while also ensuring the stability of the glass substrate on the transfer platform.
[0021] This utility model also provides a cleaning machine that, by applying the aforementioned cleaning machine transfer platform, shortens the production cycle, reduces the overall processing cycle of a single glass substrate, and improves production efficiency in large-scale mass production scenarios.

[0036] Example 1
[0037] Figure 1 This is a schematic diagram of the structure of the cleaning machine transfer platform according to Embodiment 1 of this utility model; Figure 2This is a cross-sectional view of the cleaning machine transfer platform along the AA direction in Embodiment 1 of this utility model; Figure 3 yes Figure 2 Enlarged view of the structure of part X in the middle; as shown Figures 1 to 3 As shown, the transfer platform of the cleaning machine is used to carry glass substrates and includes a first base part 1 and a second base part 2. The first base part 1 includes a first bearing plane 11 on the side facing the glass substrate along a first direction. A plurality of air suction holes 12 are provided on the first bearing plane 11 and spaced apart along a second direction. The second base part 2 includes a first guide surface 21 that is inclined on the side facing the glass substrate along the first direction. The first base part 1 and the second base part 2 are alternately arranged along a third direction.
[0038] By designing a first base portion 1 with a first bearing plane 11 and a second base portion 2 with an inclined first guide surface 21 to form a transfer platform for the cleaning machine, and by alternately arranging the first base portion 1 and the second base portion 2 along a third direction, the contact area between the transfer platform and the glass substrate is reduced on the one hand, and water on the transfer platform can be discharged through the first guide surface 21 on the other hand, avoiding the problem of water accumulation on the transfer platform. Through the above two aspects, the uncontrollable adsorption force between the glass substrate and the transfer platform is significantly reduced. Furthermore, by setting air suction holes 12 on the first bearing plane 11, the glass substrate is stably fixed on the transfer platform through controllable suction. Thus, by improving the problem of water accumulation on the transfer platform, the production cycle time of the machine is shortened, the production efficiency is improved, and the stability of the glass substrate fixed on the transfer platform is ensured.
[0039] In this embodiment, the alternating arrangement of the first base portion 1 and the second base portion 2 along a third direction can be freely selected according to requirements. For example, a second base portion 2 can be arranged between two adjacent first base portions 1, or a first base portion 1 can be arranged between two adjacent second base portions 2. Since the first guide surface 21 is provided on the second base portion 2, the contact area between the cleaning machine transfer platform and the glass substrate is reduced. In order to ensure the stability of the glass substrate fixation, when designing the suction holes 12, three suction holes 12 are provided on the first bearing plane 11, located on both sides of the first bearing plane 11 along the second direction and in the middle of the first bearing plane 11, respectively. The suction holes 12 are connected to the vacuum equipment.
[0040] Optionally, Figure 4 This is a front view of the cleaning machine transfer platform according to Embodiment 1 of this utility model; as shown Figure 4As shown, the first guide surface 21 includes a first high end 211 located at the center of the second base portion 2 and a first low end 212 located at one end of the second base portion 2 along the second direction. The second base portion 2 also includes a second guide surface 23, which is inclined and includes a second high end 231 located at the center of the second base portion 2 and a second low end 232 located at the other end of the second base portion 2 along the second direction. The first high end 211 and the second high end 231 coincide.
[0041] By providing a first guide surface 21 and a second guide surface 23 on the side of the second base portion 2 facing the glass substrate, and making the first high end 211 of the first guide surface 21 and the second high end 231 of the second guide surface 23 coincide, water flows in two different directions to both ends of the transfer platform along the second direction, so as to quickly drain the water accumulated on the transfer platform.
[0042] Optionally, such as Figure 1 , Figure 4 As shown, a transition fillet 24 is provided at the junction of the first high end 211 and the second high end 231. By providing a transition fillet 24 at the junction of the first high end 211 and the second high end 231, the junction of the first high end 211 and the second high end 231 is made smoother, thereby avoiding scratching the glass substrate at the junction of the first high end 211 and the second high end 231.
[0043] In other embodiments, in addition to providing a transition fillet 24 at the junction of the first high end 211 and the second high end 231, a connecting plane can also be provided to connect the first high end 211 and the second high end 231.
[0044] Optionally, such as Figure 4 As shown, the distance between the first high end 211 and the first low end 212 along the first direction is H1, and satisfies 2.5mm≤H1≤3.5mm.
[0045] By limiting the distance H1 between the first high end 211 and the first low end 212 along the first direction, a suitable height difference is ensured between the first high end 211 and the first low end 212. This ensures that the water flow velocity is not too slow due to a small height difference, nor that the solid part of the second base part 2 is too small due to a large height difference, thereby reducing the overall structural strength of the transfer platform.
[0046] The distance H1 between the first high end 211 and the first low end 212 along the first direction can be any value between 2.5mm and 3.5mm or any range between two values, such as 2.5mm, 3mm, 3.5mm, etc., wherein H1=3mm is preferred.
[0047] Optionally, such as Figure 4 As shown, the distance between the second high end 231 and the second low end 232 along the first direction is H2, and satisfies 2.5mm≤H2≤3.5mm.
[0048] By limiting the distance H2 between the second high end 231 and the second low end 232 along the first direction, a suitable height difference is ensured between the second high end 231 and the second low end 232. This ensures that the water flow velocity is not too slow due to an excessively small height difference, nor that the solid part of the second base part 2 is too small due to an excessively large height difference, thereby reducing the overall structural strength of the transfer platform.
[0049] The distance H2 between the second high end 231 and the second low end 232 along the first direction can be any value between 2.5mm and 3.5mm or any range between two values, such as 2.5mm, 3mm, 3.5mm, etc., wherein H2=3mm is preferred.
[0050] Optionally, Figure 5 This is a top view of the cleaning machine transfer platform according to Embodiment 1 of this utility model; as shown Figure 5 As shown, the thickness of the first substrate 1 along the third direction is T1, and it satisfies 9mm≤T1≤11mm. By limiting the thickness T1 of the first substrate 1 along the third direction to satisfy 9mm≤T1≤11mm, the first substrate 1 is ensured to have sufficient thickness. This ensures that the thickness is not too small, resulting in poor structural strength and inability to support a heavy glass substrate, nor too large, resulting in an excessively large contact area between the glass substrate and the first substrate 1, leading to excessively uncontrollable adsorption force and hindering the transfer of the glass substrate.
[0051] The thickness T1 of the first base portion 1 along the third direction can be any value between 9mm and 11mm or a range between any two values, such as 9mm, 10mm, 11mm, etc., with T1=10mm being preferred.
[0052] Optionally, such as Figure 5 As shown, the thickness of the second base portion 2 along the third direction is T2, and it satisfies 9mm≤T2≤11mm. By limiting the thickness T2 of the second base portion 2 along the third direction to satisfy 9mm≤T2≤11mm, it is ensured that the second base portion 2 has sufficient thickness. This ensures that the thickness is not too small, which would result in an insufficient flow area for guiding water flow and thus reduce the flow velocity, nor that the thickness is too large, which would result in an excessively large gap between the two first base portions 1 and reduce the overall structural strength of the transfer platform.
[0053] The thickness T2 of the second base portion 2 along the third direction can be any value between 9mm and 11mm or a range between any two values, such as 9mm, 10mm, 11mm, etc., with T2=10mm being preferred.
[0054] Optionally, such as Figure 1 , Figure 3 As shown, a plurality of liquid storage tanks 13 extending along a third direction are formed on the first bearing plane 11, and the plurality of liquid storage tanks 13 are equally spaced along the second direction. By forming a plurality of liquid storage tanks 13 on the first bearing plane 11, water on the first bearing plane 11 can flow into the liquid storage tanks 13, further reducing the contact area between the glass substrate and the first bearing plane 11, as well as the amount of water between the first bearing plane 11 and the glass substrate, thereby further reducing the uncontrollable adsorption force between the first bearing plane 11 and the glass substrate.
[0055] Optionally, such as Figure 1 , Figure 3 As shown, a drainage surface 14 is provided on the side of the liquid storage tank 13 facing the glass substrate. The height of the drainage surface 14 along the first direction gradually decreases from the center of the liquid storage tank 13 towards the second substrate 2. By providing the drainage surface 14 in the liquid storage tank 13 and making the height of the drainage surface 14 gradually decrease from the center of the liquid storage tank 13 towards the second substrate 2, water on the first bearing surface 11 is drained onto the second substrate 2 using the drainage surface 14.
[0056] In this embodiment, a cleaning machine is also provided, which includes the aforementioned cleaning machine transfer platform. By applying the aforementioned cleaning machine transfer platform, this cleaning machine shortens the production cycle, reduces the overall processing cycle of a single glass substrate, and improves production efficiency in large-scale mass production scenarios.
[0057] Example 2
[0058] Figure 6 This is a schematic diagram of the structure of the cleaning machine transfer platform according to Embodiment 2 of this utility model; Figure 6 Embodiment 2 is shown, wherein components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as those in Embodiment 1. For simplicity, only the differences between Embodiment 2 and Embodiment 1 are described.
[0059] The difference lies in that the first guiding surface 21 includes a first high end 211 located at one end of the second base portion 2 along the second direction and a first low end 212 located at the other end of the second base portion 2 along the second direction. By setting the high end of the first guiding surface 21 at one end of the second base portion 2 and setting the low end of the first guiding surface 21 at the other end of the second base portion 2, the water flow is guided to flow in a single direction, thereby enabling water recovery.
[0060] Example 3
[0061] Figure 7 This is a schematic diagram of the structure of the cleaning machine transfer platform according to Embodiment 3 of this utility model; Figure 7 Embodiment 3 is shown, wherein components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as those in Embodiment 1. For simplicity, only the differences between Embodiment 3 and Embodiment 1 are described.
[0062] The difference is that the first guide surface 21 includes a first high end 211 located at the center of the second base part 2 and a first low end 212 located at the end of the second base part 2 along the second direction. The second base part 2 also includes a second bearing plane 22, which is parallel to the first bearing plane 11 and connected to the first high end 211 of the first guide surface 21.
[0063] On the one hand, by providing a second bearing plane 22 on the side of the second base part 2 facing the glass substrate, the second bearing plane 22 cooperates with the first bearing plane 11 of the first base part 1 to increase the contact area between the transfer platform and the glass substrate and ensure the stability of the support. On the other hand, by providing an inclined first guide surface 21 on the second base part 2, the water flow is guided to flow in a single direction so as to recycle the water flow.
[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
