Description

Technical Field

[0001] This utility model relates to the field of automated guided vehicles (AGVs) specifically used for material handling, and more specifically, to a self-locking heavy-duty AGV applied to glass handling. Background Technology

[0002] AGV, short for Automated Guided Vehicle, is an intelligent material handling device that integrates electronic information technology, Internet of Things (IoT) technology, and other advanced technologies. As a mobile platform for automated transportation, the core functionality of AGVs is built upon electronic information technology. By integrating technologies such as computers, sensors, information fusion, communication, and automatic control, it achieves environmental perception, path planning, decision-making, and multi-level auxiliary functions. This integration of technologies endows AGVs with the ability to drive autonomously, navigate autonomously, and automatically transport goods, enabling them to exchange data and share information with other systems. AGVs have been widely used in various industries, including glass processing, construction, and automobile manufacturing. Taking an automated LCD panel production line as an example, AGVs are responsible for transporting glass substrates, ensuring their rapid and safe transport between the production line and specific storage equipment. This not only automates the entire process of material identification, transmission, allocation, storage, and management from production to warehousing but also significantly improves production efficiency and the safety of material handling.

[0003] Given the fragile nature of glass, special measures must be taken to ensure safety during AGV handling. To address this, Chinese Utility Model Patent ZL201921413147.8 discloses a fixing device for a magnetically guided AGV trolley. This device includes multiple positioning devices located on top of the transport trolley, as well as multiple auxiliary devices, also located on top of the trolley. The positioning devices help maintain the stability of the glass during transport, preventing it from slipping and getting damaged; the auxiliary devices facilitate unloading the glass after transport. On the one hand, this promotes rapid glass transfer and improves work efficiency; on the other hand, it protects the glass and reduces scratches during transport. The rotation of the ball bearings transforms the sliding friction of the glass into rolling friction, making glass transport more convenient. The omnidirectional rotation of the ball bearings also facilitates the movement of the glass in all directions. Through cylinders and suction cups, the glass is fixed during transport, thus protecting it and reducing the possibility of damage during trolley transport.

[0004] However, the above method uses a flat-laying method to transport glass, which can only transport one piece at a time, resulting in low transportation efficiency. In addition, for large-sized or heavy glass, it is difficult to guarantee stability during handling. Utility Model Content

[0005] To address the aforementioned technical problems, the purpose of this invention is to provide a self-locking heavy-duty AGV for glass transport. This AGV not only possesses high-efficiency transport capabilities but also ensures the stability and safety of the glass during transport. By employing self-locking technology, it can securely clamp large or heavy glass pieces, preventing shaking and slippage during handling, thereby effectively reducing the glass breakage rate. Simultaneously, this AGV also has heavy-duty capacity, enabling the transport of multiple pieces of glass at once, significantly improving transport efficiency.

[0006] To achieve the above objectives, the specific technical solution adopted by this utility model is as follows:

[0007] A self-locking heavy-duty AGV for glass transfer is characterized by the following: it includes an AGV chassis and a self-locking clamping device mounted on the AGV chassis. The self-locking clamping device includes a plurality of clamping units evenly spaced along the length of the AGV chassis. Each clamping unit includes a pair of self-locking clamps arranged opposite each other in the width direction of the AGV chassis. The distance between the clamps is adjustable, and they cooperate to clamp and fix a piece of glass.

[0008] Furthermore, the self-locking clamp includes a base and two clamping arms hinged to the base. The two clamping arms are arranged opposite each other along the length of the AGV chassis, and a clamping plate is hinged to each end of the two arms. A bearing plate is also elastically connected to the base. The bearing plate is mechanically linked to the two clamping arms through connecting rods, so as to drive the two clamping plates to move towards each other under the action of the glass's own weight, thereby achieving the clamping and fixing of the glass.

[0009] Furthermore, a flexible anti-slip pad is installed on the inside of each of the aforementioned clamps.

[0010] Furthermore, each side of the bearing plate is bent to form a wing plate, one end of the connecting rod is hinged to the wing plate, and the other end is hinged to the clamping arm on the corresponding side.

[0011] Furthermore, a telescopic guide post is installed between the bearing plate and the base, and a spring is sleeved on the telescopic guide post.

[0012] Furthermore, the clamping unit also includes a guide rail and a double-ended threaded screw arranged along the width direction of the AGV chassis. The guide rail is guided and connected to the two bases to restrict the movement direction of the two bases. The positive and negative threads of the double-ended threaded screw are respectively engaged with the two bases to adjust the distance between the two bases. The double-ended threaded screw is also connected to the output shaft of the worm gear reducer motor.

[0013] Furthermore, the worm gear reducers of two adjacent clamping units are arranged in an alternating manner.

[0014] Furthermore, several of the clamping units are integrated into a mounting frame.

[0015] Furthermore, a scissor lift device is also provided between the AGV chassis and the self-locking clamping device.

[0016] Furthermore, the AGV chassis achieves movement and turning along a predetermined path through Mecanum wheels.

[0017] The significant advantages of this invention are:

[0018] (1) The self-locking clamping device ensures stable clamping of large or heavy glass, effectively preventing shaking and slippage during handling, thereby significantly reducing the breakage rate of the glass. In addition, setting multiple clamping units enables the transportation of multiple pieces of glass at one time, significantly improving transportation efficiency;

[0019] (2) The spacing between the two self-locking clamps is designed to be adjustable to accommodate glass of various sizes, thereby enhancing the versatility and flexibility of the equipment. In addition, the spacing of the self-locking clamps in each clamping unit can be controlled individually to ensure that the needs of transporting multiple different sizes of glass in one operation can be met;

[0020] (3) The self-locking clamp is mechanically linked between the elastically connected bearing plate and the clamping arm. When the bearing plate is pressed down by the weight of the glass, the clamping arm will automatically move inward to clamp the glass with the clamping plate, thus realizing the self-locking function. The whole process does not require additional power, and the structure is compact and highly reliable.

[0021] (4) By using a double-headed ball screw and a worm gear reducer motor to adjust the distance between a pair of self-locking clamps, this design not only improves the adjustment accuracy, but also ensures the stability of the adjustment process, making the adjustment of the distance more precise and able to meet the adjustment requirements for small differences in glass size.

[0022] (5) By adopting a scissor lift device, the height of the self-locking clamping device can be adjusted, which facilitates the transfer of glass between worktables or production lines of different heights, further improving the practicality and convenience of AGV.

[0023] (6) The AGV chassis uses Mecanum wheels as the walking and steering mechanism, which enables the AGV to move flexibly in complex environments and easily realize various movement modes such as forward, backward, left and right translation and rotation in place, thereby improving the transfer efficiency and flexibility, making the entire transfer process more automated and intelligent, reducing labor costs and improving production efficiency.

Detailed Implementation

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. 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.

[0035] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] Figures 1 to 8 The first embodiment of the present invention is shown: a self-locking heavy-duty AGV for glass transfer, including an AGV chassis 1 and a self-locking clamping device 2 disposed on the AGV chassis 1, wherein: the self-locking clamping device 2 includes a plurality of clamping units 21 disposed at equal intervals along the length direction of the AGV chassis 1, each clamping unit 21 including a pair of self-locking clamps 211 disposed opposite to each other in the width direction of the AGV chassis 1, the distance between the two is adjustable, and they cooperate to clamp and fix a piece of glass 4.

[0037] like Figure 2 As shown, in a specific implementation, the self-locking clamp 211 includes a base 2111 and two clamping arms 2112 hinged to the base 2111. The two clamping arms 2112 are arranged opposite to each other along the length of the AGV chassis 1, and a clamping plate 2113 is hinged to each end of each arm. A bearing plate 2114 is also elastically connected to the base 2111. The bearing plate 2114 is mechanically linked to the two clamping arms 2112 through connecting rods 2115, so that the two clamping plates 2113 can be driven to move towards each other under the weight of the glass 4, thereby achieving the clamping and fixing of the glass 4. Preferably, a flexible anti-slip pad 2116 is installed on the inner side of each clamping plate 2113.

[0038] Specifically, each side of the support plate 2114 is bent to form a wing plate. One end of the connecting rod 2115 is hinged to the wing plate, and the other end is hinged to the clamping arm 2112 on the corresponding side. A telescopic guide post 2117 is installed between the support plate 2114 and the base 2111, and a spring 2118 is sleeved on the telescopic guide post 2117.

[0039] When the glass 4 is placed on the support plate 2114, its weight compresses the spring 2118, causing the support plate 2114 to descend. This, in turn, pushes the two clamping arms 2112 to rotate in opposite directions via the connecting rod 2115, thereby causing the clamping plate 2113 to move closer to the glass 4 until the flexible anti-slip pad 2116 is tightly pressed against the surface of the glass 4, achieving a stable clamping of the glass 4. This design not only ensures the safety and stability of the glass 4 during transport but also effectively avoids damage caused by shaking or collision. Furthermore, the telescopic guide post 2117 not only provides guidance for the spring 2118 but also enhances the structural strength of the entire self-locking clamp 211, improving its service life.

[0040] Please see Figure 3 and Figure 4 In actual use, the clamping unit 21 also includes a guide rail 212 and a double-ended threaded screw 213 arranged along the width direction of the AGV chassis 1. The guide rail 212 is guided and connected to the two bases 2111 to limit the movement direction of the two bases 2111. The positive and negative threads of the double-ended threaded screw 213 are respectively engaged with the two bases 2111 to adjust the distance between the two bases 2111. The double-ended threaded screw 213 is also connected to the output shaft of the worm gear reducer motor 214 for transmission.

[0041] Driven by the worm gear reducer motor 214, the double-headed lead screw 213 can rotate in both directions, thereby driving the two bases 2111 to move relative to or away from each other along the guide rail 212, achieving precise adjustment of the distance between the two clamping mechanisms. This design not only improves the adaptability and flexibility of the self-locking clamp 211, enabling it to clamp glass 4 of different sizes, but also ensures the stability and safety of the glass 4 during transportation. Simultaneously, the guide rail 212 further enhances the guidance and stability of the base 2111's movement, improving the overall working efficiency and reliability of the self-locking clamp 211. Preferably, to make the weight distribution of the self-locking clamping device 2 more balanced, the worm gear reducers 214 of adjacent clamping units 21 are staggered, and several clamping units 21 are integrated into a mounting frame 22.

[0042] like Figure 5 and Figure 6As shown, in this embodiment, a scissor lift device 3 is also provided between the AGV chassis 1 and the self-locking clamping device 2. The AGV chassis 1 achieves movement and turning along a predetermined path via Mecanum wheels 101. The scissor lift device 3 allows for height adjustment between the AGV chassis 1 and the self-locking clamping device 2, thereby adapting to the needs of transporting glass 4 at different heights. By adjusting the scissor lift device 3, it can be ensured that the self-locking clamping device 2 is always maintained at a suitable height, facilitating stable clamping and transport of the glass 4. At the same time, the use of Mecanum wheels 101 makes the AGV chassis 1 more flexible in movement and turning, easily handling various complex transport scenarios.

[0043] In summary, this utility model employs a self-locking clamping device 2, which ensures stable clamping of large or heavy glass 4, effectively preventing shaking and slippage during handling, thereby significantly reducing the breakage rate of the glass 4. Furthermore, the multiple clamping units 21 enable the simultaneous transport of multiple pieces of glass 4, significantly improving transport efficiency; the spacing between the two self-locking clamps 211 is adjustable to accommodate glass 4 of various sizes, thus enhancing the versatility and flexibility of the equipment. Furthermore, the spacing of the self-locking clamps 211 within each clamping unit 21 can be individually controlled, ensuring that the needs of transporting multiple different sizes of glass 4 in a single operation can be met. The self-locking clamps 211 are mechanically linked to the support plate 2114 and the clamping arm 2112 through a flexible connection. When the support plate 2114 is pressed down by the weight of the glass 4, the clamping arm 2112 automatically moves inward to clamp the glass 4 using the clamping plate 2113, achieving a self-locking function. The entire process requires no additional power, is compact, and has high reliability. By using a double-headed ball screw and a worm gear reducer motor 214 to adjust the spacing of a pair of self-locking clamps 211, this design not only improves the adjustment accuracy but also ensures the smoothness of the adjustment process. This allows for more precise spacing adjustments, meeting the needs for adjusting minute differences in the dimensions of glass 4. The use of a scissor lift device 3 enables height adjustment of the self-locking clamping device 2, facilitating the transfer of glass 4 between workbenches or production lines at different heights, further enhancing the practicality and convenience of the AGV. The AGV chassis 1 employs Mecanum wheels 101 as its walking and steering mechanism, enabling the AGV to move flexibly in complex environments, easily achieving various movement modes such as forward, backward, left and right translation, and rotation in place. This improves transfer efficiency and flexibility, making the entire transfer process more automated and intelligent, reducing labor costs, and increasing production efficiency.

[0044] Finally, it should be noted that the technical solutions disclosed above are only a preferred embodiment of this utility model, and should not be construed as limiting the scope of this utility model. Those skilled in the art can understand that implementing all or part of the processes of the above embodiments and making equivalent changes in accordance with the claims of this utility model still fall within the scope of this utility model.
