Description

Technical Field

[0001] This utility model relates to the field of glass substrate packaging rack technology, and in particular to an unpacking platform for a glass substrate packaging rack. Background Technology

[0002] In the LCD panel industry, the packaging racks for glass substrates from different glass suppliers generally have similar shapes, as shown in the attached image. Figure 1 Type A and attached Figure 2 The Type B glass substrate packaging rack shown (Type A and Type B are not actual model names) basically includes a base plate 210, a side plate 220, and a slanted plate 230. The side plate 220 is perpendicular to the base plate 210. The slanted plate 230 is angled and connected to the base plate 210 and the side plate 220 at both ends. The slanted plate 230 is used to place glass substrates. After a specified number of glass substrates are placed on the slanted plate 230, the glass substrate packaging rack is wrapped with a film or other covering. When LCD panel manufacturers use glass substrates, they need to unpack the glass substrate packaging rack. That is, first, the glass substrate packaging rack is fixed and positioned on the unpacking platform, then the film is removed, and finally, the glass substrate is taken out.

[0003] Because glass substrate packaging racks on the market come in various sizes, the unpacking platforms used to unpack them must be compatible. However, the different sizes of glass substrate packaging racks necessitate the use of multiple unpacking platforms; that is, one unpacking platform can only hold one type of glass substrate packaging rack, and one platform cannot be compatible with multiple types of glass substrate packaging racks. To unpack glass substrate packaging racks of different sizes, multiple unpacking platforms are required, leading to inconvenience in use. Utility Model Content

[0004] In view of the above problems, this utility model solves the problem that an unpacking platform cannot be compatible with multiple glass substrate packaging frames by setting multiple air-floating platforms to support the glass substrate packaging frame on the unpacking platform and fixing glass substrate packaging frames of different sizes by using moving parts.

[0005] The unpacking platform for a glass substrate packaging rack provided by this utility model adopts the following technical solution: An unpacking platform for a glass substrate packaging rack, comprising: The unpacking platform workbench is configured to be supported and placed on the ground for placing glass substrate packaging racks; Multiple air-floating platforms are disposed on the worktable of the unpacking platform to support the glass substrate packaging racks to be unpacked. When the air passage of each air-floating platform is open, the air-floating platform is configured to move in a suspended state within a set plane range; when the air passage of each air-floating platform is closed, the air-floating platform is configured to self-lock and fix itself. Multiple adjustment devices are mounted on the worktable of the unpacking platform. Each adjustment device is equipped with a movable component capable of linear motion within a set stroke. When the glass substrate packaging rack is unpacked, the base plate of the glass substrate packaging rack can be supported on the worktable of the unpacking platform. The air passage of the air-floating platform is open, and the moving part moves to push the glass substrate packaging rack to a set position. After the glass substrate packaging rack can be pushed to the set position, the air passage of the air-floating platform is closed, and the moving part can abut against the base plate of the glass substrate packaging rack to fix the glass substrate packaging rack.

[0006] Furthermore, the plurality of adjustment devices are arranged in pairs opposite to each other.

[0007] Furthermore, the plurality of adjusting devices includes a first adjusting device and a second adjusting device. The first set of adjustment devices is arranged in pairs facing each other longitudinally on the workbench of the unpacking platform. The set of second adjustment devices are arranged in pairs facing each other on the horizontal side of the workbench of the unpacking platform, and the horizontal side is perpendicular to the vertical side.

[0008] Furthermore, the unpacking platform workbench includes a first workbench and a second workbench. The first workbench and the second workbench are arranged at an interval, and the tabletops of the first workbench and the second workbench are connected by a first connecting beam. A control cabinet is provided in the space between the two first workbenches and the second workbench. The control cabinet is used to control the movement of the moving part and the opening and closing of the air circuit of the air flotation table.

[0009] Furthermore, the set of first adjustment devices includes a first adjustment section, a second adjustment section, a third adjustment section, and a fourth adjustment section. The first adjustment part and the second adjustment part are spaced apart and disposed on side A of the first worktable, and the third adjustment part and the fourth adjustment part are spaced apart and disposed on side B of the second worktable, with the first adjustment part and the third adjustment part facing each other, and the second adjustment part and the fourth adjustment part facing each other; and A second adjusting device includes a fifth adjusting section, a sixth adjusting section, a seventh adjusting section, and an eighth adjusting section. The fifth adjustment part is located on the C side of the first worktable, the sixth adjustment part is located on the D side of the first worktable, and the fifth adjustment part is opposite to the sixth adjustment part; the seventh adjustment part is located on the E side of the second worktable, and the eighth adjustment part is located on the F side of the second worktable, and the seventh adjustment part is opposite to the eighth adjustment part. The first adjustment part, the second adjustment part, the third adjustment part, the fourth adjustment part, the fifth adjustment part, the sixth adjustment part, the seventh adjustment part, and the eighth adjustment part are all provided with the moving part.

[0010] Furthermore, a position sensor is also installed on the workbench of the unpacking platform. The position sensor is used to detect the position of the glass substrate packaging frame and / or the moving part. When the position sensor detects that the glass substrate packaging rack or the moving part is in a set position, the moving part stops moving.

[0011] Furthermore, the moving component is equipped with wheels and a pivot perpendicular to the surface of the unpacking platform's worktable. The wheel has a degree of freedom to rotate about the axis of rotation. The moving part contacts the base plate of the glass substrate packaging frame via the wheels.

[0012] Furthermore, the adjustment device converts the rotational motion of the servo motor output shaft into the linear motion of the moving part through a screw and nut pair.

[0013] Furthermore, the unpacking platform workbench has limit posts at its edge.

[0014] Furthermore, it also includes: Lateral guiding and limiting devices, wherein the lateral guiding and limiting devices are arranged opposite each other on the ground and located in front of the unpacking platform workbench; and A forward limiting device, wherein the two forward limiting devices are arranged opposite each other on the ground and are located directly in front of the lateral guiding limiting device.

[0015] Beneficial effects: The movable component of the unpacking platform workbench provided by this utility model can move to the outer periphery of the glass substrate packaging rack base plate and push the glass substrate packaging rack, which is floatingly supported on the air-bearing platform, to a set position, thereby achieving the effect of position adjustment of the glass substrate packaging rack. After the position adjustment of the glass substrate packaging rack is completed, the movable component can fix the glass substrate packaging rack to the outer periphery of the glass substrate packaging rack base plate. For glass substrate packaging racks of different sizes, the movable component and the air-bearing platform can cooperate to push the glass substrate packaging rack placed on the unpacking platform to a suitable position and fix it, solving the technical problem that one unpacking platform cannot be compatible with multiple glass substrate packaging racks.

Detailed Implementation

[0021] The technical solutions in the embodiments of this utility model are described clearly and in detail below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used in this utility model specification is for the purpose of describing particular embodiments only and is not intended to limit the utility model.

[0022] The embodiments of the present invention will now be described in detail. However, the present invention may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that the present invention may be thoroughly and completely conveyed to those skilled in the art.

[0023] Please refer to the following: Figures 3 to 4 This embodiment provides an unpacking platform 100 for a glass substrate packaging rack, which includes an unpacking platform workbench, a set of first adjustment devices, a set of second adjustment devices, and multiple air-floating platforms 70.

[0024] In this embodiment, the unpacking platform workbench is generally square and is fixed to the ground by support legs. The unpacking platform workbench is used to support the glass substrate packaging rack 200. A set of first adjustment devices is installed on two opposite sides of the unpacking platform workbench, and a set of second adjustment devices is installed on the other two opposite sides of the unpacking platform workbench.

[0025] A set of first adjusting devices is installed perpendicular to the direction of a set of second adjusting devices. The first adjusting devices can adjust the position of the glass substrate packaging rack 200 along a first direction, and the second adjusting devices can adjust the position of the glass substrate packaging rack 200 along a second direction. The first and second directions are perpendicular to each other. In this embodiment, the first direction is referred to as longitudinal, and the second direction as transverse.

[0026] The unpacking platform workbench includes a first workbench 101, a second workbench 13, and a first connecting beam 15. The first workbench 101 and the second workbench 13 are separate workbenches connected by the first connecting beam 15. The glass substrate packaging rack 200 is supported and placed on the first workbench 101 and the second workbench 13. In other embodiments, the unpacking platform workbench may be a single, integrated workbench, rather than a combination of the first workbench 101 and the second workbench 13.

[0027] A set of first adjustment devices includes a first adjustment part 31, a second adjustment part 33, a third adjustment part 35, and a fourth adjustment part 37. The first adjustment part 31 and the second adjustment part 33 are spaced apart on the first side (denoted as side A) of the first worktable 101, and the third adjustment part 35 and the fourth adjustment part 37 are spaced apart on the second side (denoted as side B, which is opposite to side A) of the second worktable 13, with the first adjustment part 31 and the third adjustment part 35 facing each other, and the second adjustment part 33 and the fourth adjustment part 37 facing each other.

[0028] A second set of adjustment devices includes a fifth adjustment unit 51, a sixth adjustment unit 53, a seventh adjustment unit 55, and an eighth adjustment unit 57. The fifth adjustment unit 51 and the sixth adjustment unit 53 are disposed opposite each other on the third side (denoted as side C) and the fourth side (denoted as side D) of the first worktable 101. Side C and side D are opposite sides, and both sides C and D are perpendicular to sides A and B. The seventh adjustment unit 55 and the eighth adjustment unit 57 are disposed opposite each other on the fifth side (denoted as side E) and the sixth side (denoted as side F) of the second worktable 13. Side E and side F are opposite each other, and both sides E and F are perpendicular to sides A and B.

[0029] The eight adjustment units, from the first adjustment unit 31 to the eighth adjustment unit 57, each have a moving component, namely the first moving component, the second moving component, the third moving component, the fourth moving component, the fifth moving component, the sixth moving component, the seventh moving component, and the eighth moving component. Each of the eight adjustment units also has a servo motor, namely the first servo motor, the second servo motor, the third servo motor, the fourth servo motor, the fifth servo motor, the sixth servo motor, the seventh servo motor, and the eighth servo motor. The eight adjustment units convert the rotational motion of the output shaft of their respective servo motors into linear motion of their respective moving components within a set stroke through a screw-nut pair. The servo motors offer high control precision, enabling accurate control of the movement of the moving components.

[0030] Specifically, when the first moving member of the first adjusting part 31 and the second moving member of the second adjusting part 33 move toward the glass substrate packaging frame 200, they can push the glass substrate packaging frame 200 along the longitudinal positive direction (see attached diagram). Figure 3 When the moving parts on the third adjustment section 35 and the fourth adjustment section 37 move toward the glass substrate packaging frame 200 (marked as longitudinal +), they can push the glass substrate packaging frame 200 in the negative longitudinal direction (attached). Figure 3 The middle part is marked as longitudinal (-). When the fifth moving member of the fifth adjusting unit 51 and the seventh moving member of the seventh adjusting unit 55 move toward the glass substrate packaging frame 200, they can push the glass substrate packaging frame 200 in the positive direction of the transverse direction (see attached). Figure 3 The sixth moving member of the sixth adjusting unit 53 and the eighth moving member of the eighth adjusting unit 57 move toward the glass substrate packaging frame 200, which is marked as a horizontal +), can push the glass substrate packaging frame 200 in the negative horizontal direction (attached) when they move toward the glass substrate packaging frame 200. Figure 3 The movement is marked as horizontal (-). The movement of the eight moving parts pushes the glass substrate packaging rack 200 on the air-floating platform 70 to move horizontally and vertically, thereby adjusting the planar position of the glass substrate packaging rack 200. In this embodiment, four adjustment parts are provided in both the horizontal and vertical directions, so that when the moving parts on the adjustment parts push the glass substrate mounting rack 200, the glass substrate mounting rack 200 is subjected to balanced force, is not prone to rotation, and the position adjustment is easier to control. In other embodiments, the number of adjustment devices and their corresponding orientation can be set according to specific needs. For example, if the positional requirements of the glass substrate packaging rack 200 are not very high, only one set of first adjustment devices can be provided to adjust only the vertical position of the glass substrate packaging rack 200. As another example, each of the first adjustment device and the second adjustment device can include only two opposing adjustment parts, in which case only four adjustment parts are needed in total.

[0031] An air-bearing stage 70 is disposed on the worktable of the unpacking platform to support the glass substrate packaging rack 200 to be unpacked. When the air passage of the air-bearing stage 70 is open, the air-bearing stage 70 is configured to move in a suspended state within a set plane range; when the air passage of the air-bearing stage 70 is closed, the air-bearing stage 70 is configured to self-lock.

[0032] During unpacking, the base plate 210 of the glass substrate packaging rack 200 is placed on the unpacking platform workbench in the area enclosed by a set of first adjustment devices and a set of second adjustment devices (the enclosed area refers to the area enclosed by a circle formed by connecting the moving parts on the set of first adjustment devices and the set of second adjustment devices). That is, the set of first adjustment devices and the set of second adjustment devices are located on the outer periphery of the base plate 210 of the glass substrate packaging rack 200 (more precisely, the moving parts on the set of first adjustment devices and the set of second adjustment devices are located on the outer periphery of the base plate 210 of the glass substrate packaging rack 200). The air passage of the air-floating platform 70 is opened, and the moving parts on the first and second adjusting devices move linearly in the longitudinal and transverse directions, respectively, thereby pushing the glass substrate packaging rack 200 to the set position. After the glass substrate packaging rack 200 is pushed to the set position, the air passage of the air-floating platform 70 is closed, and the first and second adjusting devices abut against the base plate 210 of the glass substrate packaging rack 200. That is, the glass substrate packaging rack 200 is fixed around its perimeter by the first and second adjusting devices, thus fixing the glass substrate packaging rack 200 on the unpacking platform worktable. After the glass substrate packaging rack 200 is fixed on the unpacking platform worktable, the outer covering of the glass substrate packaging rack 200 can be removed by a robotic arm or other automated or non-automated means, and the glass substrate on the glass substrate packaging rack 200 can be picked up.

[0033] In this embodiment, with the air passage of the air-floating platform 70 open, the linear motion of the moving parts on the first and second adjusting devices allows for the relatively small force to push the glass substrate packaging frame 200 supported on the air-floating platform 70 to a set position, thus achieving the function of adjusting the position of the glass substrate packaging frame 200. After the position of the glass substrate packaging frame 200 is adjusted, the air passage of the air-floating platform 70 can be closed, causing the air-floating platform 70 to self-lock and fix, preventing the glass substrate packaging frame 200 from shaking. Simultaneously, the first and second adjusting devices fix the glass substrate packaging frame 200 from the outer periphery of the glass substrate packaging frame base plate 210. Because the moving parts on the first and second adjusting devices are movable, they can be moved to different positions to form areas of different sizes. Therefore, this unpacking platform 100 is suitable for unpacking glass substrate packaging frames 200 of different sizes, solving the problem that one unpacking platform 100 cannot be compatible with multiple glass substrate packaging frames 200.

[0034] Taking type A and type B glass substrate packaging racks of different sizes as examples, the area S2 of the base plate 210 of the type A glass substrate packaging rack is defined as being larger than the area S3 of the base plate 210 of the type B glass substrate packaging rack. In this case, a first stop position, a second stop position, and a third stop position can be set within the linear motion stroke of the moving parts of the first adjustment section 31 to the eighth adjustment section 57. When the moving part is at the first stop position, the area enclosed by the moving part is equal to S1; when the moving part is at the second stop position, the area enclosed by the moving part is equal to S2; and when the moving part is at the third stop position, the area enclosed by the moving part is equal to S3. S1 is larger than the base plate area S2 of the type A glass substrate packaging rack and also larger than the base plate area S3 of the type B glass substrate packaging rack.

[0035] When the moving part is at the first stop position, it waits for either the Type A or Type B glass substrate packaging frame 200 to be placed on the unpacking platform worktable. After the Type A glass substrate packaging frame is placed on the air-floating platform 70 of the unpacking platform worktable, the moving part moves from the first stop position to the second stop position. During the movement, the position of the Type A glass substrate packaging frame can be adjusted. When the moving part reaches the second stop position, the position adjustment of the Type A glass substrate packaging frame is complete. At this time, the moving part abuts against the base plate 210 of the Type A glass substrate packaging frame, thus fixing the Type A glass substrate packaging frame. Similarly, after the Type B glass substrate packaging frame is placed on the air-floating platform 70 of the unpacking platform worktable, the moving part moves from the first stop position to the third stop position. During the movement, the position adjustment of the Type B glass substrate packaging frame can be completed. When the moving part reaches the third stop position, the position adjustment of the Type B glass substrate packaging frame is complete. At this time, the moving part abuts against the base plate 210 of the Type B glass substrate packaging frame, thus fixing the Type B glass substrate packaging frame. It should be noted that in this embodiment, the linear movement of the moving member is bidirectional; that is, the moving member can move linearly from the first stop position to the second and third stop positions, and also from the second and third stop positions to the first stop position. Furthermore, if the unpacking platform 100 is configured to accommodate glass substrate packaging racks of three or more sizes, corresponding third and fourth stop positions can also be provided.

[0036] In this embodiment, the moving part has a preset stop position. Depending on the model of the glass substrate packaging frame, the moving part can move to the stop position corresponding to that model of glass substrate packaging frame. During the process of moving to the corresponding stop position, the moving part can push the glass substrate packaging frame 200 to move, thereby adjusting the position of the glass substrate packaging frame 200. When the moving part moves to the corresponding stop position, the moving part abuts against the bottom plate 210 of the glass substrate packaging frame 200, thereby fixing the glass substrate packaging frame 200 on the unpacking platform workbench.

[0037] More specifically, in this embodiment, the unpacking platform workbench is further equipped with eight first position sensors, eight second position sensors, and eight third position sensors. The eight first position sensors are respectively located at the first stop positions of the first adjustment section 31 to the eighth adjustment section 57, the eight second position sensors are located at the second stop positions of the first adjustment section 31 to the eighth adjustment section 57, and the third position sensors are located at the third stop positions of the first adjustment section 31 to the eighth adjustment section 57. By detecting whether the moving part has moved to the set stop position using position sensors, it is unnecessary to detect the position of the glass substrate packaging rack 200, thus reducing the complexity of the device. The sensor type can be a photoelectric sensor. In this case, a light-shielding plate can be provided on the moving part, and the light-shielding plate moves with the moving part. When the moving part moves to the first stop position, the second stop position, or the third stop position, the photoelectric sensor at the corresponding stop position can detect the moving part, thereby enabling the control device to control the moving part to stop moving.

[0038] In other embodiments, a position sensor mounted on the unpacking platform workbench can detect the position of the glass substrate packaging rack 200 instead of the moving part. When the position sensor detects that the glass substrate packaging rack 200 is in a set position, the control device stops the moving part. In this way, different types of glass substrate packaging racks 200 can be preset with corresponding positions on the unpacking platform workbench 20 according to their type. The position sensor can then detect whether the position of the glass substrate packaging rack 200 meets the preset position. If not, the moving part can be used to push the glass substrate packaging rack 200 to adjust its position. This control method is relatively easy to implement. For example, it can specifically detect whether the edge of the base plate 210 of the glass substrate packaging rack 200 meets the preset position requirements.

[0039] More specifically, in this embodiment, the moving part is provided with wheels, which can rotate around the pivot of the vertical unpacking platform workbench. The moving part directly contacts the bottom plate 210 of the glass substrate packaging rack 200 through the outer peripheral surface of the wheels. Different areas of the outer peripheral surface of the wheels can abut against the bottom plate 210 of the glass substrate packaging rack 200, avoiding the moving part from always contacting the glass substrate packaging rack 200 in a fixed position and reducing the wear of the moving part.

[0040] As an improvement, refer to Figure 3 and Figure 4The unpacking platform 100 is also equipped with a limiting post 300. The limiting post 300 is located on one edge of the unpacking platform workbench and extends vertically upwards. The limiting post 300 is used to prevent the glass substrate packaging rack from exceeding the edge of the unpacking platform workbench 10 when placed. Specifically, the limiting post 300 is located on one edge of the first workbench 101 (A side mentioned above). When the glass substrate packaging rack 200 is forked from one side of the second workbench 13 (B side mentioned above) onto the unpacking platform workbench 10 by a forklift, the glass substrate packaging rack 200 may exceed the edge of the first workbench 101. The limiting post 300 can avoid this problem and improve safety.

[0041] Reference Figure 3 and Figure 4 In this embodiment, a control cabinet is installed in the space between the first workbench 101 and the second workbench 13, that is, below the first connecting beam 15. The control cabinet can control the movement of the moving parts in the eight adjustment sections and the opening and closing of the air passage of the air flotation platform 70. Because the unpacking platform workbench support legs are often equipped with a second connecting beam, if only one workbench is set, it is inconvenient for personnel to enter under this workbench to install the control cabinet. Even if the control cabinet is installed under this workbench in advance, it is inconvenient for maintenance personnel to enter under this workbench later because of the obstruction of the second connecting beam. In this embodiment, two spaced first workbench 101 and second workbench 13 are set up, which can make full use of the space between the two workbench to install the control cabinet. At this time, it is not affected by the second connecting beam, and the installation and maintenance of the control cabinet are very convenient.

[0042] As a further improvement, refer to Figures 3 to 4The unpacking platform 100 also includes two lateral guide limiting devices spaced apart on both sides of the ground. These devices limit the wheels on both sides of the forklift, ensuring that the forklift travels between them when transporting the glass substrate packaging rack 200 to the unpacking platform workbench. Each lateral guide limiting device includes a side baffle 510 and a spring 520 connected to the side of the side baffle 510. When the forklift deviates from the set travel path, one wheel of the forklift presses against the side baffle 510 on the same side, compressing the spring 520 connected to the pressed side baffle 510. When the glass substrate packaging rack 200 is transported to the unpacking platform 100 by a forklift, the forklift driver's direct view is easily obstructed by the large glass substrate packaging rack 200, making it difficult to park the forklift at a suitable distance from the unpacking platform 100. This results in the glass substrate packaging rack 200 being improperly positioned on the unpacking platform workbench. The side guide limit device can limit the wheels when the forklift driver's driving path deviates. Moreover, when the wheels collide with each other, the driver can feel the wheels hitting the obstacle, thus allowing him to adjust the driving direction in time and bring the forklift back to the correct preset route, improving the accuracy of placing the glass substrate packaging rack on the unpacking platform.

[0043] In addition, in this embodiment, the unpacking platform 100 also includes two forward limiting devices 600 disposed opposite to each other on the ground, located directly in front of the two lateral guiding limiting devices. When the forklift transports the glass substrate packaging rack 200 to the unpacking platform workbench, it can stop in time when the forklift wheels contact the forward limiting device 600. Thus, the lateral guiding limiting device ensures that the driving route does not deviate from the correct direction, and the forward limiting device 600 ensures that the forklift stops at a preset suitable position. This ensures that even when the forklift driver's field of vision is limited, he can still place the glass substrate packaging rack 200 at a suitable position on the unpacking platform workbench. This suitable position refers to a position with a small deviation from the final position where the glass substrate packaging rack 200 is fixed by the moving part. In this case, subsequent adjustments to the position of the glass substrate packaging rack 200 and its final position fixing are only required according to the aforementioned method using the moving part in the adjusting device. Furthermore, through the detailed description of the technical solution in this embodiment, it can be seen that the unpacking platform 100 provided in this embodiment can easily realize an automated workflow and reduce the workload of personnel.

[0044] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
