Description

Technical Field

[0001] This utility model relates to the field of display materials technology, and in particular to a substrate mounting device. Background Technology

[0002] In the electronic information display industry, substrate glass and carrier glass, as key strategic materials, directly determine the performance and competitiveness of downstream display products, and are core foundational components supporting the high-quality development of the display industry. In the processing of substrate glass and carrier glass, the glass must first be precisely transferred from storage trays to the flow processing station on the production line. This transfer step is a crucial process connecting glass storage and subsequent processing, and its stability and efficiency have a significant impact on the overall production cycle.

[0003] With the continuous iteration of display technology, terminal display products are rapidly developing towards larger sizes and higher resolutions, driving the continuous increase in the size of substrate glass and carrier glass. Simultaneously, the industry's demand for glass production capacity is also increasing, placing higher demands on the technology of the glass input process. Currently, the industry commonly uses robots to complete the glass input process from pallets to the production line. This technology is suitable for the handling and input of small-area glass.

[0004] However, existing robotic deployment technologies for large-size substrate glass and carrier glass have significant limitations: on the one hand, the long travel distance of the robots, the cumbersome operation steps, and the large range of motion result in a significant reduction in the glass deployment speed. It takes about 30 minutes to complete the deployment of a single large-size glass, which seriously slows down the production cycle and makes it difficult to match the current demand for increased production capacity. On the other hand, during the handling of large-size glass, due to its increased size and width, it is prone to shaking due to the range of motion of the robots. Glass is highly brittle, and shaking can easily cause breakage, resulting not only in material loss but also further interruption of the production process, exacerbating the contradiction between production capacity and demand.

[0005] Therefore, there is an urgent need to propose a wafer loading device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve or at least alleviate some or all of the aforementioned problems. Therefore, the purpose of this invention is to provide a glass loading device to adapt to the needs of large-size glass input, reduce the risk of glass breakage, save production costs, avoid production process interruptions due to glass breakage, ensure the stable operation of automated production equipment, increase loading speed, and improve input efficiency.

[0018] In some optional embodiments, the suction cup nozzle is made of rubber; and / or,

[0019] The suction cup holder is made of carbon steel.

[0020] In some optional embodiments, the adsorption assembly further includes a connector disposed at the output end of the lifting drive assembly, the suction cup holder being rotatably connected to the connector, and the transfer mechanism further includes an angle drive assembly disposed on the connector, the angle drive assembly being driven at its output end to the suction cup holder for driving the suction cup holder to rotate.

[0021] In some alternative embodiments, the middle part of the suction cup holder is rotatably connected to the connector, and the angle driving assembly includes at least two angle driving members, which are respectively drivenly connected to both ends of the suction cup holder.

[0022] In some optional embodiments, preparation areas corresponding to the loading area are respectively provided on both sides of the conveyor belt.

[0025] This utility model provides a glass loading device, including a shelf, a conveyor belt, a support, and a transfer mechanism corresponding to each loading area.

The output end of the horizontal drive component is driven by the lifting drive component to drive the lifting drive component to move the adsorption component between the corresponding loading area and the conveyor belt in a horizontal straight line. By setting loading areas on both sides of the conveyor belt, the glass handling journey can be shortened, reducing transfer time. At the same time, with the synergistic effect of the horizontal drive component and the lifting drive component, the glass transfer action is decomposed into horizontal linear displacement and vertical linear displacement, which greatly simplifies the transfer steps, reduces the mechanical movement amplitude, effectively suppresses the shaking phenomenon of large-size glass during the movement, and thus significantly reduces the risk of glass breakage and avoids production process interruption caused by glass breakage. In addition, the improved stability of glass operation provides a safe premise for increasing the transfer speed. At the same time, each transfer mechanism is configured to alternately supply glass to the conveyor belt, thereby achieving continuous feeding. The synergistic effect of the two significantly improves the loading speed and increases the input efficiency. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0041] In this invention, the terms "comprising," "including," "having," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0042] In this invention, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following related objects have an "and / or" relationship.

[0043] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," "fixed," "combined," "coupled," and "installed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can be a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For example, a direct connection refers to two parts or components being connected together without an intermediate component, while an indirect connection refers to two parts or components each being connected to at least one intermediate component, with the connection achieved through the intermediate component. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Furthermore, "connected" and "coupled" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0044] In this invention, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0047] like Figure 1 and Figure 2 As shown, this embodiment provides a glass loading device, including a shelf 1, a conveyor belt 2, a support 4, and a transfer mechanism 5 corresponding to the loading areas 3. The shelf 1 is used to carry glass 100. At least one loading area 3 is provided on each side of the conveyor belt 2 for placing the shelf 1. The support 4 is arranged across the conveyor belt 2. The transfer mechanism 5 is installed on the support 4 and includes a horizontal drive component, a lifting drive component 52, and an adsorption component 53. The adsorption component 53 is configured to absorb or release glass 100. The output end of the lifting drive component 52 is connected to the adsorption component 53 for driving the adsorption component 53 to move vertically. The output end of the horizontal drive component is connected to the lifting drive component 52 for driving the lifting drive component 52 to move the adsorption component 53 between the corresponding loading area 3 and the conveyor belt 2 along a horizontal straight line.

[0048] By setting up upper areas 3 on both sides of the conveyor belt 2, the transport stroke of glass 100 can be shortened, reducing the transfer time. At the same time, with the synergistic effect of the horizontal drive component and the lifting drive component 52, the transfer action of glass 100 is decomposed into horizontal linear displacement and vertical linear displacement, which greatly simplifies the transfer steps and reduces the mechanical movement amplitude. This can effectively suppress the shaking phenomenon of large-size glass 100 during the movement, thereby significantly reducing the risk of glass 100 breakage and avoiding production process interruption caused by glass 100 breakage.

[0049] Furthermore, the improved operational stability of the glass 100 provides a safe premise for increasing the transfer speed. At the same time, each transfer mechanism 5 is configured to alternately supply glass 100 to the conveyor belt 2, thereby achieving continuous feeding. The synergistic effect of the two significantly improves the loading speed and increases the input efficiency.

[0050] Each transfer mechanism 5 is connected to the control system via signals. The control system can control the working sequence of each transfer mechanism 5 to coordinate with each other, so as to alternately supply glass 100 to the conveyor belt 2. Optionally, the control system includes, but is not limited to, a PLC or an industrial computer, which is not limited here.

[0051] In some optional embodiments, the horizontal drive assembly includes a horizontal drive component 51 and a threaded screw and nut. The axis of the screw is parallel to the horizontal movement direction of the adsorption component 53. The nut is fixedly connected to the lifting drive assembly 52. ​​The output end of the horizontal drive component 51 is connected to the screw for driving the screw to rotate, thereby driving the lifting drive assembly 52 to move via the nut, so that the adsorption component 53 is transferred between the corresponding upper area 3 and the conveyor belt 2 along a horizontal straight line. The screw and nut use a precision threaded meshing transmission, with controllable clearance and high transmission rigidity, which can effectively suppress the shaking caused by the movement between components during transmission. The screw axis is parallel to the horizontal movement direction of the adsorption component 53, ensuring that the driving force is accurately transmitted along the preset movement direction, avoiding lateral shaking caused by force direction deviation, so that the adsorption component 53 always maintains a stable posture when moving with the nut, effectively reducing the shaking amplitude of the large-size glass 100 during horizontal movement and reducing the risk of breakage.

[0052] The horizontal drive component 51 includes, but is not limited to, a motor or electric motor, which is not specified herein.

[0053] Optionally, the lifting drive assembly 52 may include, but is not limited to, a pneumatic cylinder or a hydraulic cylinder, which is not limited herein.

[0054] In some optional embodiments, the transfer mechanism 5 further includes a guide assembly comprising a slidingly engaged guide rail 54 and a guide block. The guide rail 54 is arranged parallel to the lead screw, and the guide block is fixedly connected to the lifting drive assembly 52. ​​This provides guidance for the horizontal linear movement of the lifting drive assembly 52 and the adsorption assembly 53, further improving the stability of the large-size glass 100 during horizontal movement and reducing the risk of breakage.

[0055] Each transfer mechanism 5 can share a guide rail 54 or have its own independent guide rail 54; similarly, each transfer mechanism 5 can share a lead screw or have its own independent lead screw, and there is no limitation here.

[0056] like Figure 1 and Figure 4 As shown, in some optional embodiments, the loading device further includes a positioning component 6, which includes a first positioning element 61 and a second positioning element 62. The bracket 4 is provided with a first positioning element 61 corresponding one-to-one with the conveyor belt 2 and each loading area 3, and each lifting drive component 52 is provided with a second positioning element 62. One of the first positioning element 61 and the second positioning element 62 is a sensor, and the other is a first detection element used to detect the sensor. Through the combination of the sensor and the first detection element, the position information of the adsorption component 53 can be fed back in real time and accurately, avoiding errors in film picking and placing due to positional deviations. This effectively ensures the positioning consistency of the adsorption component 53 when switching between different working areas, reducing the accumulation of positional errors. Simultaneously, the sensing detection method has a rapid response and strong anti-interference capability, which can improve the stability of positioning signal transmission, thereby ensuring the overall accuracy and reliability of the loading device and reducing the risk of operational failures.

[0057] For example, the sensing element is a metal block, and the first detection element is an inductive proximity switch, which triggers the signal by detecting changes in the electromagnetic field caused by the metal object; or, the sensing element is a permanent magnet, and the first detection element is a magnetoresistive sensor, which triggers the signal by detecting changes in the resistance value caused by changes in the magnetic field.

[0058] Furthermore, a second detection element is provided on the conveyor belt 2 for detecting the glass 100. When the second detection element detects the glass 100, the conveyor belt 2 runs and feeds the glass 100 into the input port of the downstream equipment; when the second detection element does not detect the glass 100, the conveyor belt 2 stops running and waits for the transfer mechanism 5 to load the glass, so as to ensure the stability of the loading process and further reduce the risk of breakage.

[0059] The conveyor belt 2 and its driving mechanism are existing technologies and will not be described in detail here.

[0060] Optionally, the second detection element may include, but is not limited to, a weight sensor or a photoelectric sensor, which is not limited here.

[0061] like Figure 1 and Figure 3As shown, in some optional embodiments, the adsorption assembly 53 includes a suction cup frame 531, multiple suction cup nozzles 532, and a negative pressure source. The suction cup frame 531 is disposed at the output end of the lifting drive assembly 52. ​​The multiple suction cup nozzles 532 are arranged in an array on the suction cup frame 531, and each suction cup nozzle 532 is connected to the negative pressure source through an air passage for adsorbing the glass 100. The arrayed multiple suction cup nozzles 532, in conjunction with the negative pressure source, can form a uniform and multi-point adsorption force on the large-sized glass 100, effectively dispersing the stress on the glass 100 and avoiding excessive local stress that could cause the glass 100 to break. The suction cup frame 531 provides a stable mounting base for the suction cup nozzles 532, ensuring the consistency of the array layout, making the adsorption force distribution even, reducing deformation or shaking of the glass 100 due to uneven force during handling, and ensuring the safety and stability of the glass 100 during handling. The negative pressure source is connected to each suction cup nozzle 532 through the air passage, which can quickly establish and maintain a stable negative pressure, ensuring the reliability of adsorption, while facilitating unified control of adsorption and release actions and improving the ease of operation.

[0062] In some optional embodiments, the suction cup nozzle 532 is made of rubber. Rubber has good elasticity and sealing properties; when in contact with the surface of glass 100, it can deform to conform to the surface of glass 100, enhancing the airtightness of negative pressure adsorption, improving adsorption stability, and reducing the risk of adsorption failure due to air leakage. Furthermore, the soft texture of rubber can buffer the impact force during the adsorption process, preventing hard contact from causing scratches or damage to the surface of glass 100, thus protecting the appearance quality of glass 100.

[0063] In some optional embodiments, the suction cup holder 531 is made of carbon steel, which has high strength and rigidity, and can stably support the weight of multiple suction cup nozzles 532 and glass 100, effectively resisting external forces and deformations during operation, and ensuring the stability of the overall structure of the adsorption assembly 53.

[0064] In addition, carbon steel, while ensuring structural strength, has a relatively moderate density, which can achieve the weight reduction of suction cup 531 while meeting the load-bearing requirements of suction cup 531. This reduces the load on the horizontal drive component and the lifting drive component 52, reduces power loss, improves drive efficiency, and reduces inertia during movement, making the suction component 53 start and stop more smoothly. This reduces the shaking or positional deviation of glass 100 caused by excessive inertia, and improves operational stability.

[0065] like Figure 5 and Figure 6As shown, the glass 100 shelf 1 includes a flat shelf 1a and an A-type shelf 1b. The glass 100 is stored horizontally on the flat shelf 1a and tilted on the A-type shelf 1b. Due to the difference in the storage angle of the glass 100 on the two types of shelves 1, operational obstacles easily occur during the retrieval and placement process, affecting work efficiency. To solve the above problem, the adsorption component 53 also includes a connector 533, which is disposed at the output end of the lifting drive component 52. The suction cup frame 531 is rotatably connected to the connector 533, giving the suction cup frame 531 a degree of freedom for angle adjustment. The transfer mechanism 5 also includes an angle drive component, which is disposed on the connector 533 and its output end is drively connected to the suction cup frame 531 to drive the suction cup frame 531 to rotate, thereby adjusting the angle of the suction cup frame 531. When picking up glass 100 from shelf 1, the angle drive component can drive the suction cup holder 531 to rotate to a position that perfectly matches the storage angle of glass 100, ensuring that the suction cup is stably attached to glass 100 and improving the reliability of the picking. When the suction component 53 moves above the conveyor belt 2, the angle drive component can drive the suction cup holder 531 to rotate again, adjusting the glass 100 to a horizontal position, so that the glass 100 is arranged parallel to the conveyor belt 2, meeting the posture requirements for the smooth transfer of glass 100 to the conveyor belt 2. The above settings can flexibly adapt to different shelves 1, expanding the applicability of the loading device and improving its flexibility and practicality.

[0066] In this embodiment, the middle part of the suction cup holder 531 is rotatably connected to the connector 533. The angle driving assembly includes at least two angle driving components 55, which are respectively connected to both ends of the suction cup holder 531. The two components work together to drive the suction cup holder 531 to rotate around the connector 533 to adjust the adsorption angle. The arrangement of at least two angle driving components 55 ensures a balanced distribution of driving torque, which improves the stability and response speed of angle adjustment. The synergistic effect at both ends enhances the rigidity of angle adjustment, reduces shaking during adjustment, ensures precise matching between the suction cup holder 531 and the glass 100 storage angle, guarantees adsorption reliability, and reduces glass 100 shaking. At the same time, this structure can provide sufficient driving force to adapt to the angle adjustment requirements of glass 100 of different weights, and the design of at least two angle driving components 55 has a certain degree of redundancy, improving the stability and fault tolerance of the equipment operation.

[0067] In other alternative embodiments, one end of the suction cup holder 531 is rotatably connected to the connector 533, and the angle driving component includes an angle driving component 55, which is drively connected to the other end of the suction cup holder 531, and can also drive the suction cup holder 531 to rotate around the connector 533, which is not limited here.

[0068] The angle driving component 55 includes, but is not limited to, a pneumatic cylinder or a hydraulic cylinder, which is not specified here.

[0069] like Figure 2 As shown, in some optional embodiments, preparation areas 7 corresponding to the loading areas 3 are respectively provided on both sides of the conveyor belt 2. The loading device also includes a conveyor track 8 and a positioning drive component. The conveyor track 8 connects the loading areas 3 and the corresponding preparation areas 7. The bottom of the shelf 1 is provided with rollers. The output end of the positioning drive component can act on the shelf 1 to drive the shelf 1 to move, so that the rollers enter the conveyor track 8. The conveyor track 8 is configured to drive the shelf 1 to transfer between the preparation areas 7 and the loading areas 3. After the transfer mechanism 5 has transferred all the glass 100 on the shelf 1, the conveyor track 8 conveys the empty shelf 1 to the preparation area 7 and replaces it with a new shelf 1. When the new shelf 1 is transported to the preparation area 7, the positioning drive component drives the new shelf 1 to move to the position where its rollers are aligned with the conveyor track 8. The conveyor track 8 then conveys the new shelf 1 to the loading area 3 to continue loading. The positioning drive component drives the shelf 1 to move, so that the roller enters the conveyor track 8, ensuring the shelf 1 is accurately positioned, thereby ensuring the accuracy and consistency of the shelf 1 in the upper area 3, providing a reliable guarantee for the glass picking accuracy of the transfer mechanism 5, and helping to ensure the glass 100 input accuracy.

[0070] The conveyor track 8 includes a belt, a belt drive assembly, and a limiting track. The limiting track connects the upper area 3 with the corresponding preparation area 7. The belt is set in the limiting track, and the track drive assembly can drive the belt to run so as to drive the shelf 1 to move between the preparation area 7 and the upper area 3.

[0071] The specific structure of the belt drive assembly is existing technology and will not be described in detail here.

[0072] In some optional embodiments, the positioning drive assembly includes at least four positioning drive members 9. At least two of the positioning drive members 9 are spaced apart on both sides of the preparation area 7, and the force direction of the positioning drive members 9 is perpendicular to the extension direction of the conveyor track 8. The output end of the positioning drive member 9 can extend toward the preparation area 7 to abut and push the shelf 1 located in the preparation area 7 from both sides, so that the shelf 1 moves to a position where its rollers are aligned with the conveyor track 8. By providing at least two drive members on both sides of the preparation area 7, and applying a force perpendicular to the conveyor track 8 from both sides of the shelf 1, the multi-point coordinated abutment and push of the shelf 1 can ensure balanced force application and avoid tilting or positioning deviation of the shelf 1 caused by unilateral force.

[0073] Meanwhile, multi-point drive can adapt to possible initial positional deviations of shelf 1, and through coordinated action, precisely adjust the posture of shelf 1, ensuring accurate alignment between the rollers of shelf 1 and the conveyor track 8, providing a reliable benchmark for subsequent conveying. This design offers high positioning stability, effectively eliminating human placement errors, improving the positioning efficiency and accuracy of shelf 1, ensuring smooth subsequent conveying processes, and reducing the risk of jamming.

[0074] In this embodiment, the positioning drive 9 includes, but is not limited to, a pneumatic cylinder or a hydraulic cylinder, and is not limited thereto.

[0075] 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 other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations 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.
