Description

Technical Field

[0001] This utility model generally relates to the field of ultra-thin glass processing, and more particularly to an ultra-thin glass stacking and alignment device. Background Technology

[0002] With the increasing popularity of LCD monitors, smartphones, and tablets, display products are gradually becoming thinner and lighter. The corresponding electronic glass also needs to be thinner and lighter, leading to the development of ultra-thin glass. Ultra-thin glass (UTG), as its thickness decreases, exhibits better mechanical properties such as flexibility, making it potentially valuable for applications in flexible displays and other fields.

[0003] Because ultra-thin glass is brittle and thin, its edges are right-angled after cutting. These right-angled edges are prone to developing micro-cracks due to impacts and other factors during processing, thus affecting the lifespan of the ultra-thin glass. To remove the sharp edges of the glass after cutting and reduce the formation of micro-cracks, the edges of the ultra-thin glass are usually treated to form chamfers, making the edges smoother and effectively improving the aesthetics and safety of the ultra-thin glass. Chamfering the edges of ultra-thin glass can be done using chemical treatment or physical polishing methods. In the physical polishing process, multiple pieces of glass to be polished are manually stacked, fixed together, and then polished with a brush. During manual stacking, it is difficult to achieve a perfectly neat stack of multiple pieces of ultra-thin glass, leading to secondary damage or non-compliant chamfering during polishing.

[0005] In a first aspect, an ultrathin glass stacking alignment device is provided, comprising:

[0006] In the placement area, ultra-thin glass pieces are moved one by one to the placement area for temporary storage.

[0007] A stacking area, the size of which is the same as that of the ultra-thin glass, and which at least partially overlaps with the placement area.

[0008] At least two fixing plates are provided, which are vertically arranged and located on opposite sides of the stacking area.

[0009] At least two push plates are provided, which are arranged vertically and form a rectangular space with the fixed plate. The push plates are used to move towards the fixed plate when the ultra-thin glass is placed in the placement area, thereby pushing the ultra-thin glass to the stacking area.

[0011] As a possible implementation, it also includes: a material receiving area for temporarily storing the ultrathin glass.

[0013] As an implementation method, each of the push plates is connected to a drive mechanism, which drives the push plate to move a preset distance toward or away from the fixed plate.

[0014] As an implementation method, each of the push plates is disposed opposite to one of the fixed plates, and a pressure sensor is provided on the side of the push plate near the fixed plate to detect the pressure between the push plate and the ultra-thin glass.

[0015] As an alternative implementation, a controller is also included, for controlling the glass transfer assembly to pick up the ultra-thin glass from the receiving area and move it to the placement area;

[0016] The drive mechanism is controlled to push the push plate a preset distance toward the fixed plate.

[0017] As an alternative implementation, the controller is also configured to receive a signal from the pressure sensor and control the push plate to stop moving when the signal reaches a set value.

[0030] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Please refer to Figure 1 and Figure 2This embodiment provides an ultra-thin glass stacking alignment device, comprising:

[0033] In placement area A, ultra-thin glass pieces are moved one by one to placement area A for temporary storage.

[0034] Stacking area B, the size of which is the same as that of the ultra-thin glass, and which at least partially overlaps with the placement area A.

[0035] At least two fixing plates 11 are provided, which are arranged vertically and located on two sides of the stacking area B, respectively.

[0036] At least two push plates 12 are arranged vertically and form a rectangular space with the fixing plate 11. The push plates 12 are used to move towards the fixing plate 11 when the ultra-thin glass is placed in the placement area A, pushing the ultra-thin glass to the stacking area B.

[0037] This embodiment provides an apparatus for stacking ultra-thin glass sheets. When the ultra-thin glass is transferred to the placement area A, the pusher plate 12 pushes the ultra-thin glass to place it in the placement area A, and multiple ultra-thin glass sheets are stacked in the placement area A. In this embodiment, the ultra-thin glass sheets are moved to the placement area A one by one, and the pusher plate 12 also pushes the ultra-thin glass sheets one by one, aligning and stacking multiple ultra-thin glass sheets in the stacking area B. The fixing plate 11 fixes the position of the two intersecting edges of the ultra-thin glass sheets, so that multiple ultra-thin glass sheets are neatly stacked. In the subsequent glass edge polishing process, the edge of each glass sheet can be polished to ensure that the glass edge forms a good chamfer shape, and the ultra-thin glass can be bent well without breaking.

[0038] refer to Figure 1 and Figure 2 As shown, the device in this embodiment is provided with a placement area A and a stacking area B, and a [missing information] is provided at the location of the stacking area B. Figure 3The stacked glass fixing device 4 shown is an ultra-thin glass fixture box with two fixed components, one above the other, and connecting plates on both sides connecting the upper and lower components. The upper component 41 can move on the connecting plates to press the stacked ultra-thin glass together with the lower component 42. After a predetermined number of ultra-thin glass stacks are placed, the fixing device presses and fixes the stacked structure and transfers it to a grinding and polishing device for edge polishing. The ultra-thin glass is moved to the placement area A and then moved to the stacking area B under the push of the pusher plate 12. The stacking area B coincides with the support plate, and the center of the stacking area B coincides with the center of the support plate. After the multiple layers of ultra-thin glass are moved to the lower support plate for stacking under the push of the pusher plate 12, the upper support plate moves downward and together with the lower support plate presses the multiple layers of glass together, thus fixing the multiple layers of ultra-thin glass. Since the aforementioned glass stacking device 4 has connecting plate structures on both sides, the push plate 12 used to push the ultra-thin glass needs to be moved to the inside of the connecting plate via the track to push the ultra-thin glass. After the multi-layer glass and the pad are stacked and pressed and fixed, the corresponding push plate 12 is moved to the outside of the glass stacking device 4 via the track to facilitate the movement of the glass stacking device 4.

[0039] In this embodiment, the ultra-thin glass is moved to the placement area A, which partially overlaps with the stacking area B. This allows the glass to be smoothly pushed to the stacking area B when the pusher plate 12 pushes the ultra-thin glass, and the glass layers do not affect each other, and the surface of the ultra-thin glass is not scratched.

[0040] In this embodiment, at least two fixing plates 11 are relatively fixed. That is, during the use of this ultra-thin glass stacking alignment device, the fixing plates 11 remain stationary. The ultra-thin glass is pushed and stacked by the movement of the two push plates 12, and the fixing plates 11 serve a side alignment function. Since this embodiment uses a fixing device to press, fix, and transfer the stacked glass, the position of this fixing device is generally not easily moved. Therefore, the positions of the lower components 41 and 42 on the fixing device are also fixed and not easily moved. Therefore, the two fixing plates 11 are moved accordingly according to the different glass sizes. Each size of ultra-thin glass corresponds to a specific fixing plate 11 position, allowing it to define the position of the two intersecting edges of the ultra-thin glass. Similarly, the position of the fixing plate 11 also determines the range of the stacking area B, and the range of the stacking area B is the same depending on the glass size. (Reference) Figure 2As shown, the fixing plate 11 provided in this embodiment has at least the track in the direction of the arrow in the figure, and moves on the track to avoid obstacles before and after the ultra-thin glass is stacked, so as to facilitate the movement of the fixing device 4 for the next operation. The push plate 12 provided in this embodiment has at least the track in two directions as shown by the arrow in the figure. The push plate moves on the track, and also avoids obstacles to the fixing device 4. During the operation, the fixing device 4 is moved to the location of the stacking area B for fixing and placement. The fixing plate 11 and the push plate 12 move on the track to Figure 2 The subsequent ultrathin glass stacking process is carried out at the location shown in the figure.

[0041] Optionally, the overlapping area of ​​the stacking area B and the placement area A is greater than half the area of ​​the placement area A.

[0042] In this embodiment, the ultra-thin glass is moved to placement area A for temporary placement. Then, two push plates 12 push the glass to stacking area B for stacking. Adjacent glass panes are separated by pads. In this embodiment, pads are first placed on the support plate below the fixing device. These pads are then moved to placement area A for stacking under the push plates 12. Next, a piece of ultra-thin glass is moved to placement area A, and then, under the push plates 12, it moves to stacking area B and stacks with the pads. (Refer to...) Figure 2 As shown, in this embodiment, the stacking area B and the placement area A have a significant overlap, with the overlapping area being at least half the area of ​​the placement area A. Preferably, the overlap area between the stacking area B and the placement area A is 80%-90%, or even more than 90%. Under this condition, when the ultra-thin glass is moved to the placement area A, even if there are many ultra-thin glasses stacked in the placement area A, the next piece of glass can still be placed near the stacking area B, and the surface of the glass will not be scratched during the movement of the pusher plate 12. In this embodiment, the pusher plate 12 has a certain initial position. The driving mechanism drives the pusher plate 12 to move from the initial position to the placement area A to push the ultra-thin glass until the ultra-thin glass moves to the stacking area B.

[0043] Optionally, the rectangular space formed by the push plate 12 and the fixing plate 11 is greater than or equal to the range of the placement area A.

[0044] The initial position of the pusher plate 12 is set at the edge of the placement area A or outside the placement area A, so as not to affect the transfer and temporary storage of the ultra-thin glass.

[0045] Furthermore, it also includes: a material receiving area 3, used for temporarily storing the ultra-thin glass.

[0046] Glass transfer assembly 2, which is equipped with suction cup assembly 21, which picks up a single piece of ultra-thin glass from the receiving area 3 at a time, and moves the ultra-thin glass from the receiving area 3 to the placement area A under the drive of the glass transfer assembly 2.

[0047] like Figure 1 As shown, the device in this embodiment also includes a material receiving area 3. The glass and pads to be stacked are placed in the material receiving area 3. The material receiving area 3 is independent of the placement area A and the stacking area B and can be set up independently. The glass transfer component 2 includes a suction cup component 21, which adsorbs the glass or pad and moves it to the placement area A for stacking. The glass transfer component 2 adsorbs one sheet of ultra-thin glass and moves it to the placement area A for stacking, then adsorbs one pad and moves it to the placement area A for stacking, and then repeats the above steps to achieve a stacked structure of one sheet of glass and one pad. The adsorption force required by the suction cup component 21 when adsorbing the ultra-thin glass and the pad varies and is adjusted according to the actual situation.

[0048] The glass transfer assembly 2 can be configured in different forms, such as a six-axis robotic arm, or as... Figure 1 As shown, a vertical pole is set up, and a first horizontal bar is rotatably installed on the vertical pole. The end of the first horizontal bar is rotatably connected to a second horizontal bar, so that the suction cup assembly can traverse various positions within a certain horizontal plane. The second horizontal bar is connected to a suction cup assembly 21, and the suction cup assembly 21 can move up and down. The ultra-thin glass and the pad are adsorbed by the suction cup assembly 21. This structure is simple but effective.

[0049] Optionally, each of the push plates 12 is connected to a drive mechanism, which drives the push plate 12 to move a preset distance toward or away from the fixed plate 11.

[0050] In this embodiment, the pusher plate 12 moves to push the ultra-thin glass. The driving method of the pusher plate 12 is not limited. For example, a pneumatic device can be used as the driving mechanism. The pneumatic device is set to move a preset distance each time. This distance is adjusted according to the different sizes of the ultra-thin glass, that is, the different ranges of the stacking area B each time. Before use, it is pre-adjusted to ensure that the pusher plate 12 can push the ultra-thin glass to the stacking area B for stacking without causing pressure damage to the ultra-thin glass.

[0051] Optionally, each of the push plates 12 is disposed opposite to one of the fixed plates 11, and a pressure sensor is provided on the side of the push plate 12 near the fixed plate 11 to detect the pressure between the push plate 12 and the ultra-thin glass.

[0052] To improve the automation and digitalization of the device, a pressure sensor is installed on the pusher plate 12. When the pusher plate 12 pushes the ultra-thin glass to the stacking area B, the force applied by the pusher plate 12 to the ultra-thin glass is detected in real time. When the ultra-thin glass moves to the stacking area B and the other two sides contact the fixing plate 11, the drive mechanism stops driving the pusher plate 12 to push the ultra-thin glass and moves back to the initial position of the pusher plate 12.

[0053] Furthermore, it also includes: a controller for controlling the glass transfer assembly 2 to pick up the ultra-thin glass from the receiving area 3 and move it to the placement area A;

[0054] The drive mechanism is controlled to push the push plate 12 to move a preset distance toward the fixed plate 11.

[0055] The device provided in this embodiment is an automated equipment. A controller is configured to control the movement of the glass transfer assembly 2, as well as the moving direction and distance of the pusher plate 12. After the ultra-thin glass is placed in the receiving area 3, the controller controls the glass transfer assembly 2 to pick up a piece of ultra-thin glass from the receiving area 3 and move it to the placement area A. Subsequently, the controller controls the pusher plate 12 to push the ultra-thin glass from two different directions, moving it to the stacking area B for stacking, until the stacking operation is completed. The controller can pre-set the moving distance of the pusher plate 12, with the pusher plate 12 moving the same distance each time, pushing the ultra-thin glass or a pad to the stacking area.

[0056] Furthermore, the controller is also used to receive the signal from the pressure sensor and control the push plate 12 to stop moving when the signal reaches a set value.

[0057] The pressure on the push plate 12 can also be detected in real time by a pressure sensor. The controller receives the detection data from the pressure sensor and determines whether the ultra-thin glass has moved to the stacking area. If it is determined that the ultra-thin glass has moved to the stacking area, the controller controls the push plate 12 to return to the initial position and wait for the next movement.

[0058] Optionally, a clearance space 13 is provided at the intersection of the two fixed plates 11 or at the extended intersection.

[0059] like Figure 1 As shown, the two fixing plates 11 provided in this embodiment are not connected. The intersection of the two fixing plates 11 is set to avoid the sharp corner of the ultra-thin glass. When the ultra-thin glass moves to the stacking area, the top corner will not be hit and break. Alternatively, the two fixing plates 11 are connected, and a hollowed-out space is set at the connection position to avoid the sharp corner of the ultra-thin glass.

[0060] In addition, an elastic sheet is attached to the side of the fixing plate 11 near the stacking area B provided in this embodiment. By using elastic materials such as silicone sheets to flexibly protect the side of the fixing plate 11 that is in contact with the ultra-thin glass, the ultra-thin glass will not be damaged due to contact with the fixing plate 11.

[0061] The ultra-thin glass stacking alignment device provided in this embodiment can be used for ultra-thin glass stacks of different sizes. When the size of the ultra-thin glass is changed, the glass can be stacked by adjusting the position of the fixing plate 11.

[0062] The device provided in this embodiment is used in the edge polishing and grinding step of ultra-thin glass. During the stacking of multiple ultra-thin glass sheets, this device can achieve precise stacking of multiple ultra-thin glass sheets, making it less likely for glass to shift, which is beneficial to the subsequent polishing step, resulting in ultra-thin glass with better quality and higher yield.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0064] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features.
