Description

Technical Field

[0001] This invention relates to the field of glass tray positioning technology, and more specifically to a glass tray positioning device. Background Technology

[0002] Large-sized substrate glass is typically packaged using vertical A-frames or horizontal boxes. When glass is placed into the workstation for production purposes, forklifts or AGVs are usually used to transport the packaged glass to the placement station, where robots pick up and place the sheets. When glass is placed into the packaging station, forklifts or AGVs are usually used to transport empty vertical A-frames or horizontal boxes to the packaging station, where robots collect and package the sheets.

[0003] Currently, both of these requirements necessitate precise positioning of the vertical A-frame or horizontal packaging box to facilitate robotic wafer receiving and retrieval. However, the weight of a single G8.5 substrate glass packaging box and A-frame is approximately 3 tons, making manual handling, guidance, and precise alignment a time-consuming and labor-intensive process. Furthermore, excessive pushing force during the glass tray alignment process can cause deformation of the tray and positioning device, leading to deformation of the reference surface, requiring manual compensation. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to disclose a positioning device for a glass tray, so as to improve the problem that the existing glass trays are not positioned accurately when entering the work station and are prone to deformation of the glass tray or positioning device.

[0005] To achieve the above and other related objectives, the present invention discloses a positioning device for a glass tray, comprising:

[0006] A base having a horizontal base surface, and a first lifting module being provided on the base;

[0007] Multiple positioning blocks are fixedly connected to the base, and the positioning blocks protrude from the base surface;

[0008] A multi-directional sliding wheel assembly is connected to the first lifting module, and the base surface is located within the lifting area of ​​the multi-directional sliding wheel assembly, and the glass tray plate to be positioned is located on the multi-directional sliding wheel assembly;

[0009] Multiple limiting mechanisms are located on the periphery of the base, and an entrance is reserved between the multiple sets of limiting mechanisms. The limiting mechanisms are used to drive the glass tray to move on the multi-directional sliding wheel assembly.

[0010] Multiple positioning mechanisms are located at the entrance, and a second lifting module is connected to each positioning mechanism. The second lifting module drives the positioning mechanisms to move along the normal direction of the base surface, wherein the positioning mechanisms are used to drive the glass tray to move on the multi-directional sliding wheel assembly; and

[0011] The controller is electrically connected to the first lifting module, the second lifting module, the limiting mechanism, and the positioning mechanism, and the controller controls the on / off state or running state of the first lifting module, the second lifting module, the limiting mechanism, and the positioning mechanism respectively according to the positioning process of the glass tray.

[0012] In one embodiment of the present invention, the base comprises two sets, and the two sets of bases are arranged in parallel.

[0013] In one aspect of the present invention, the plurality of limiting mechanisms comprises two sets, and the two sets of limiting mechanisms are symmetrically arranged.

[0014] In one embodiment of the present invention, a pre-guide plate is further included, and the limiting mechanism is located on the pre-guide plate; wherein, the pre-guide plate includes:

[0015] A horizontal connecting plate and a vertical connecting plate are arranged perpendicularly to each other; and guide surfaces are provided at both ends of the vertical connecting plate, with the guide surfaces forming an angle with the side surface of the vertical connecting plate.

[0016] In one embodiment of the present invention, the limiting mechanism and the positioning mechanism have the same structure, which includes a cylinder and a guide wheel, and the guide wheel is located on the cylinder rod of the cylinder.

[0017] In summary, this invention discloses a positioning device for a glass tray. By arranging a multi-directional sliding wheel assembly vertically and flexibly on a base, the glass tray moves on the substrate in a low-thrust engagement state. Simultaneously, the limiting and positioning mechanisms ensure that the glass tray is gently pushed into place during positioning. Furthermore, there is no relative sliding between the glass tray and the base surface during positioning, enabling precise positioning of the glass tray. This effectively improves upon existing methods that result in inaccurate positioning of glass trays upon entering the workstation, and the tendency for deformation of the glass tray or positioning device.

[0024] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0025] Please see Figures 1 to 3 It should be noted that the structures, proportions, sizes, etc., shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and objectives that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0026] Please see Figure 1As shown, this invention discloses a positioning device for a glass pallet, which can improve the problem of insufficient positioning of the existing glass pallet 10 when entering the workstation, and the tendency to deform the glass pallet 10 or the positioning device. The positioning device for the glass pallet 10 may include a base 2, a multi-directional sliding wheel assembly 3, multiple limiting mechanisms 6, multiple positioning mechanisms 7, and a controller. Specifically, a horizontal surface is formed on the base 2, and the glass pallet 10 is allowed to lie on this horizontal surface. Therefore, the glass pallet 10 pallet for positioning is positioned on the base 2, so that the base 2 can support the glass pallet 10. The multi-directional sliding wheel assembly 3 is located on the base 2, so that the glass pallet 10 can slide in multiple directions on a single plane on the base 2 via the multi-directional sliding wheel assembly 3, thereby adjusting the specific position of the glass pallet 10. Simultaneously, the limiting mechanisms 6 and the positioning mechanisms 7 are used to adjust the position of the glass pallet 10, thereby improving the positioning accuracy of the glass pallet 10. Furthermore, the limiting mechanism 6 and the positioning mechanism 7 are electrically connected to the controller so that the controller can regulate the operating status of the limiting mechanism 6 and the positioning mechanism 7 according to the positioning process of the glass tray 10.

[0027] Please see Figure 1 and Figure 2 As shown, in one embodiment, the base 2 may include two sets, and the two sets of base 2 are symmetrically arranged. Therefore, a transport channel 11 is formed between the two bases 2, serving as the passage for the AGV transport trolley or forklift forks to enter and exit. The base 2 is equipped with a first lifting module and a positioning block 1, and a multi-directional sliding wheel set 3 is connected to the first lifting module. Therefore, the multi-directional sliding wheel set 3 allows for position adjustment via the first lifting mechanism. It should be noted that the specific structure of the second lifting module can be determined according to actual needs. For example, the second lifting module may use a servo electric cylinder or a pneumatic cylinder, but is not limited to these. The positioning block 1 is fixedly connected to the base 2, and the positioning block 1 protrudes from the base surface to achieve positioning processing of the glass tray 10.

[0028] The lifting range of the multi-directional sliding wheel assembly 3 is located on both sides of the base surface on the base 2. For example, the lifting positions of the multi-directional sliding wheel assembly 3 can include a first position and a second position, where the first position is above the base surface and the second position is below the base surface. Therefore, when the multi-directional sliding wheel assembly 3 is in the first position, the glass tray 10 is located on the multi-directional sliding wheel assembly 3, and the glass tray 10 can be moved by the multi-directional sliding wheel assembly 3 without contact with the base surface. After the position of the glass tray 10 is adjusted, the multi-directional sliding wheel assembly 3 is in the second position, at which point the glass tray 10 is located on the base surface of the base 2, thereby achieving the positioning of the glass tray 10.

[0029] Please see Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the limiting mechanism 6 is used to drive the glass tray 10 to move on the multi-directional sliding wheel group 3, and the multiple limiting mechanisms 6 are located on the periphery of the base 2, with an entrance 601 reserved between the multiple limiting mechanisms 6. Therefore, the glass tray 10 enters the upper part of the base 2 through the entrance 601, thereby facilitating the placement of the glass tray 10 on the base 2. The multiple limiting mechanisms 6 may include two sets, and the two sets of limiting mechanisms are symmetrically arranged. Furthermore, the specific number of limiting mechanisms 6 contained within a single set of limiting mechanisms can be determined according to actual needs.

[0030] It should be noted that the limiting mechanism 6 is connected to the pre-guide plate 4, and the pre-guide plate 4 includes at least a transverse connecting plate 402 and a vertical connecting plate 401. The transverse connecting plate 402 and the vertical connecting plate 401 are arranged perpendicularly, and guide surfaces 403 are respectively provided at the ends of the vertical connecting plate 401. The guide surfaces 403 are set at an angle to the side of the vertical connecting plate 401, so that the glass tray 10 can easily enter the area enclosed by the limiting mechanism 6 through the guide surfaces 403. Stainless steel is permissible for the pre-guide plate 4.

[0031] Specifically, it also allows for the inclusion of multiple pre-guide wheels 9, with one set on each side of the pre-guide wheels 9, and each set containing at least one guide wheel 5. Therefore, the pre-guide wheels 9 can effectively adjust the direction of the glass pallet 10 when it enters the positioning device. Thus, the pre-guide wheels 9 and the pre-guide plate 4 can be used in conjunction with the AGV's navigation function to provide auxiliary guidance for pallet handling.

[0032] The limiting mechanism 6 includes a cylinder and a limiting wheel, with the limiting wheel rotatably connected to the cylinder rod. The limiting wheel can be made of either plastic-coated steel or rubber, but is not limited to these materials and can be determined according to actual needs.

[0033] Therefore, when the glass tray 10 enters the area enclosed by the limiting mechanism 6 from the entrance 601 position, the limiting mechanism 6 on both sides can be used to limit the glass tray 10.

[0034] Please see Figure 1 , Figure 2 and Figure 3As shown, in one embodiment, the positioning mechanism 7 is used to drive the glass tray 10 to move on the multi-directional sliding wheel assembly 3, and the positioning mechanism 7 is located at the entrance 601, and the positioning mechanism 7 is allowed to move along the normal direction of the base surface on the base 2. Therefore, by setting the positioning mechanism 7 to a liftable state, the glass tray 10 can enter above the base 2. At the same time, after the limiting mechanisms 6 on both sides of the glass tray 10 perform the limiting treatment of the glass tray 10, the position of the positioning mechanism 7 can be adjusted to achieve the positioning treatment of the glass tray 10.

[0035] Specifically, a second lifting module may be connected to the positioning mechanism 7 to achieve lifting and lowering of the positioning mechanism 7. It should be noted that the specific structure of the second lifting module can be determined according to actual needs. For example, the second lifting module may use a servo electric cylinder or a pneumatic cylinder, but it is not limited to these.

[0036] It should be noted that in one embodiment, the limiting mechanism 6 and the positioning mechanism 7 have the same structure, both including a motor and a guide wheel 5, and the guide wheel 5 is rotatably connected to the cylinder rod of the cylinder. Therefore, it is permissible to drive the guide wheel 5 via an electric cylinder, thereby driving the glass tray 10 into the appropriate position.

[0037] The controller is electrically connected to the first lifting module, the second lifting module, the limit mechanism 6, and the positioning mechanism 7. The controller controls the on / off state or running state of the first lifting module, the second lifting module, the limit mechanism 6, and the positioning mechanism 7 according to the positioning process of the glass tray 10.

[0038] Specifically, the controller's control method in the positioning process of the glass tray 10 includes the following steps.

[0039] S10. Adjust the second lifting module to ensure that the entrance 601 constructed by the multiple limit mechanisms 6 is in a passable state. The passable state of the entrance 601 indicates that the glass tray 10 is allowed to pass through the entrance 601.

[0040] S20. Adjust the first lifting module to ensure that the multi-directional sliding wheel group 3 is higher than the base surface of the base 2, that is, adjust the multi-directional sliding wheel group 3 to be in the first position.

[0041] S30. When the glass tray 10 enters the area enclosed by multiple limiting mechanisms 6, the limiting mechanisms 6 are driven to achieve the initial positioning of the glass tray 10.

[0042] S40. Adjust the second lifting module so that the adjustment mechanism points to the side of the glass tray 10 and drives the positioning mechanism 7 to achieve the final positioning of the glass tray 10.

[0043] S50. After the glass tray 10 is positioned, adjust the first lifting module to ensure that the multi-directional sliding wheel group 3 is lower than the base surface of the base 2, that is, adjust the multi-directional sliding wheel group 3 to be in the second position. At this time, the glass tray 10 is located on the base 2, thus completing the positioning process of the glass tray 10.

[0044] For example, in one embodiment, the glass pallet 10 can be transported by an automatically receiving AGV (Automated Guided Vehicle). When the glass pallet 10 needs to be moved in, the AGV transport vehicle moves the glass pallet 10 to the workstation, and the glass pallet 10 is guided into the glass pallet 10 positioning device after passing through the front pre-guide wheels 9 and the pre-guide plate 4.

[0045] Secondly, after the positioning device of glass pallet 10 detects glass pallet 10, the multi-directional sliding wheel group 3 rises and receives glass pallet 10, and the AGV transport trolley or forklift exits. During the glass pallet 10 transfer process, there is no sliding contact between the bottom of glass pallet 10 and the base surface. The limiting mechanism 6 laterally and precisely aligns the glass pallet 10, and the positioning mechanism 7 rises and longitudinally and precisely aligns the glass pallet 10.

[0046] Furthermore, it is permissible to detect and confirm via photoelectric signals that after the glass tray 10 has reached the designated position, the multi-directional sliding wheel group 3 falls down to make the glass tray 10 land on the base surface, and during this process, there is no sliding contact between the bottom of the glass tray 10 and the base surface when the glass tray 10 is moved out.

[0047] Simultaneously, when the glass in the glass tray 10 needs to be removed, the multi-directional sliding wheel assembly 3 rises, and the glass tray 10 detaches from the base surface. This allows the AGV transport trolley to remove the glass tray 10 from the positioning device, and during this process, there is no sliding contact between the bottom of the glass tray 10 and the base surface.

[0048] In summary, this invention discloses a positioning device for a glass tray. By arbitrarily mounting a multi-directional sliding wheel assembly 3 on a base 2, the glass tray 10 moves on the substrate in a low-push contact state. Simultaneously, the limiting mechanism 6 and the positioning mechanism 7 ensure that the glass tray 10 is in a light-push-alignment state during positioning. Furthermore, there is no relative sliding between the glass tray 10 and the base surface of the base 2 during positioning, thus achieving precise positioning of the glass tray 10. Therefore, this effectively improves upon existing methods that result in inaccurate positioning of the glass tray 10 upon entering the workstation, and the tendency for deformation of the glass tray 10 or the positioning device.

[0049] Therefore, this invention effectively overcomes some practical problems in the prior art, thus having high utilization value and significance.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
