Description

Technical Field

[0001] This utility model relates to the field of fragile material transportation technology, and in particular to a multi-layer glass handling device adapted to AGV. Background Technology

[0002] As a fragile and heavy material, glass usually requires specialized equipment for handling and transshipment during industrial production and logistics to prevent it from tipping over or breaking.

[0003] Traditional glass handling relies primarily on manual labor, using forklifts with specialized protective transfer frames or robotic arms with suction cups for unloading. While these methods address basic glass handling needs to some extent, they suffer from high labor costs, low automation, and significant safety risks. Especially in multi-layered glass handling scenarios, improper handling can easily lead to glass tipping or damage.

[0004] To reduce reliance on manual labor and improve handling efficiency, some semi-automated glass handling devices have emerged in the existing technology. For example, Chinese utility model patent CN120172104A discloses a glass handling and installation device, including a base frame. The base frame includes an external fixing rod, a bottom rod, a top rod, an upright rod, side rods, and a bottom center fixing rod. The upright rod, side rods, and external fixing rod are connected in a triangular formation. A top rod is installed on the upright rod, a fixing mechanism is installed on the side rod, an adjustment mechanism is installed on the bottom center fixing rod, a lifting mechanism is installed on the upright rod, and casters are installed at the four corners of the bottom of the external fixing rod. This device uses suction cups to adhere to the glass and uses handwheels, screws, and other adjustment mechanisms to fine-tune the glass's position on the horizontal plane, and uses the lifting mechanism to change the height of the glass, thereby adapting to the handling and installation of glass of different sizes. However, the shortcomings of this device are: First, the device requires manual operation, such as turning a handwheel or crank to adjust its position and height, making it impossible to achieve fully unmanned handling, and it is especially unsuitable for automated logistics systems such as automated guided vehicles (AGVs).

[0005] Secondly, it mainly focuses on the handling and installation of single-layer glass, without addressing the needs of stacking and handling multi-layer glass, and lacks structural design to accommodate different numbers of glass layers.

[0006] Furthermore, the device's fixing mechanism mainly relies on suction cups for adsorption, and it lacks an adaptive pressure plate angle structure, making it unable to adapt to glass placed at different tilt angles.

[0007] Therefore, there is an urgent need for a handling device that can be adapted to AGVs, realize fully automated unmanned handling, and provide anti-tipping, anti-breakage, and angle adaptive functions for multi-layered glass. Utility Model Content

[0008] The technical problem to be solved by this utility model is how to design a fully automatic glass handling device adapted to AGVs that can adapt to glass stacking at different tilt angles and prevent tipping.

[0009] To solve the above-mentioned technical problems, this utility model provides a multi-layer glass handling device adapted to AGV, including a base assembly connected to and driven by AGV, wherein the base assembly is provided with: The pressure plate telescopic mechanism is configured to move toward or away from the glass stack to adaptively press or release the glass stack; The anti-tipping mechanism of the transfer frame is configured such that before the pressure plate telescopic mechanism presses the glass stack, the anti-tipping mechanism of the transfer frame descends and contacts and fixes itself to the glass transfer frame to stabilize the glass transfer frame.

[0010] Furthermore, the pressure plate telescopic mechanism includes a pressure plate assembly and a telescopic assembly connected to each other, wherein: The telescopic component is fixedly connected to the base assembly; The pressure plate assembly adaptively fits glass stacks at different tilt angles.

[0011] Furthermore, the pressure plate assembly includes a push plate seat and a pressure plate, the pressure plate being rotatably and fixedly connected to the push plate seat, and a spring being provided between the pressure plate and the push plate seat.

[0012] Furthermore, the pressure plate is hinged and fixed to the push plate seat.

[0013] Furthermore, the spring connects the pressure plate and the push plate seat via a spring fixing seat.

[0014] Furthermore, the upper and lower edges of the pressure plate in the vertical direction are provided with edge switches. After the pressure plate comes into contact with and presses against the glass stack, the edge switches respond to stop the telescopic component from moving.

[0015] Furthermore, a foamed rubber protective layer is arranged on the contact surface between the pressure plate and the glass stack.

[0016] Furthermore, the telescopic assembly includes a scissor fork assembly and a hydraulic drive assembly. The scissor fork assembly is provided in two sets, and the hydraulic drive assembly is located in the middle of the two sets of scissor fork assemblies. The hydraulic drive assembly drives the scissor fork assembly to extend or retract, thereby driving the pressure plate assembly to telescopically move.

[0017] Furthermore, the hydraulic drive assembly includes a telescopic cylinder, the oil inlet circuit of which is equipped with a pressure sensor and an overflow valve, and a first balance valve self-locking valve is also provided between the overflow valve and the telescopic cylinder.

[0018] Furthermore, the anti-tipping mechanism of the transfer frame includes at least two grippers and a double-pressing hydraulic cylinder. The grippers are driven to descend by the double-pressing hydraulic cylinder to hold the glass transfer frame in place.

[0019] Furthermore, the oil inlet circuit of the dual downward pressure cylinder is equipped with a second balance valve self-locking valve.

[0020] Compared with the prior art, the embodiments of this utility model have the following beneficial effects: This invention achieves adaptive pressing and flexible contact with glass of different stacking angles and layers through a pressure plate telescopic mechanism, effectively preventing glass breakage during handling. At the same time, the anti-tipping mechanism of the transfer frame actively locks the edge of the transfer frame after pressing, fundamentally solving the risk of glass transfer frame tipping during AGV handling. The two work together to achieve safety, stability and adaptability in the glass handling process. Attached Figure Description

Detailed Implementation

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] The present invention aims to provide a multi-layer glass handling device adapted to AGVs, which can adapt to glass stacking with different tilt angles and different numbers of layers and has an anti-tipping function.

[0026] Please see Figure 1-2 The system mainly includes a base assembly 1000, on which a pressure plate telescopic mechanism 1100 and a transfer frame anti-tipping mechanism 1200 are installed. The base assembly 1000 is fixedly connected to the AGV body via a standard interface and is powered by the AGV. The pressure plate telescopic mechanism 1100 is configured to move toward or away from the glass stack 0001 to adaptively press or release the glass stack 0001. The transfer frame anti-tipping mechanism 1200 is configured to descend and contact and fix with the glass transfer frame 0000 before the pressure plate telescopic mechanism 1100 presses the glass stack 0001, thus stabilizing the glass transfer frame 0000.

[0027] First, please refer to Figure 3-4 The following is a detailed description of the pressure plate telescopic mechanism 1100.

[0028] The pressure plate telescopic mechanism 1100 includes a pressure plate assembly 1110 and a telescopic assembly 1120 connected to each other, wherein the telescopic assembly 1120 is fixedly connected to the base assembly 1000; the pressure plate assembly 1110 adaptively fits the glass stacks 0001 with different tilt angles.

[0029] Regarding pressure plate assembly 1110: The pressure plate assembly 1110 includes a push plate seat 1111 and a pressure plate 1112. The pressure plate 1112 is rotatably and fixedly connected to the push plate seat 1111. A spring 1113 is provided between the pressure plate 1112 and the push plate seat 1111. The spring 1113 connects the pressure plate 1112 and the push plate seat 1111 through a spring fixing seat 1114. Preferably, the pressure plate 1112 is hinged and rotatably fixed to the push plate seat 1111, so that the pressure plate 1112 can swing freely within a certain angle around the hinge point. In a specific embodiment, the angle by which the pressure plate 1112 can rotate around the hinge point is 0-10°.

[0030] During operation, when the pressure plate 1112 contacts the inclined glass stack 0001 surface, the pressure plate 1112 will automatically deflect under the elastic action of the spring 1113 until the entire surface of the pressure plate 1112 is completely in contact with the inclined glass surface. This design transforms traditional line or point contact into uniform surface contact, greatly dispersing the clamping force and avoiding glass breakage caused by stress concentration.

[0031] To further enhance safety, contact switches are installed on the upper and lower edges of the pressure plate 1112 in the vertical direction. After the pressure plate 1112 contacts and presses against the glass stack 0001, the contact switches respond to stop the extension and pushing action of the telescopic component 1120, preventing glass breakage due to overpressure. At the same time, a layer of foamed rubber protective layer 1112a is arranged on the contact surface between the pressure plate 1112 and the glass stack 0001, which can further buffer vibration, absorb impact, and increase friction to protect the glass surface from scratches.

[0032] Regarding telescopic component 1120: The telescopic assembly 1120 includes a scissor fork assembly 1121 and a hydraulic drive assembly. There are two sets of scissor fork assemblies 1121. The hydraulic drive assembly is located in the middle of the two sets of scissor fork assemblies 1121. The hydraulic drive assembly drives the scissor fork assembly 1121 to extend or retract, thereby driving the pressure plate assembly 1110 to telescopically move.

[0033] The hydraulic drive assembly includes a telescopic cylinder 1122, whose oil inlet circuit is equipped with a pressure sensor and an overflow valve. The overflow valve sets the maximum permissible working pressure of the system. When the pressure plate assembly 1110 contacts the glass, the system pressure increases. Once the overflow valve's set value is reached, the oil circuit overflows, ensuring that the pressure of the pressure plate 1112 on the glass does not exceed the safety threshold. This is the core guarantee against glass breakage. The pressure sensor is used to collect the system pressure value in real time and feed it back to the AGV's host computer control system, enabling real-time pressure monitoring.

[0034] In addition, a first balance valve self-locking valve 1123 is provided between the overflow valve and the telescopic cylinder 1122. The function of the first balance valve self-locking valve 1123 is to lock the hydraulic oil in the telescopic cylinder 1122 after the pressure plate 1112 presses the glass, so as to prevent the pressure plate 1112 from accidentally retracting due to oil leakage or pipeline rupture, and to ensure the persistence and stability of the pressing state.

[0035] Next, please refer to Figure 5 The following is a detailed description of the anti-tipping mechanism 1200 for the transfer frame.

[0036] The anti-tipping mechanism 1200 for the transfer frame includes at least two grippers 1210 and dual downward hydraulic cylinders 1220. The grippers 1210 are driven to descend by the downward hydraulic cylinders 1220 to secure the glass transfer frame 0000. In addition, the oil inlet circuit of the downward hydraulic cylinders 1220 is equipped with a second balance valve self-locking valve 1221.

[0037] During operation, after the AGV travels to the target workstation, the first mechanism activated is not the pressure plate telescopic mechanism 1100, but the anti-tipping mechanism 1200 of the transfer frame. The pressing cylinder 1220 drives the gripper 1210 downward until it firmly latches onto the edge of the glass transfer frame 0000 or a specific structure. During this process, the second balance valve self-locking valve 1221 ensures that the pressing cylinder 1220 can be reliably locked after descending to its position, preventing it from retracting under gravity or vibration.

[0038] The anti-tipping mechanism 1200 of the transfer frame ensures that when the pressure plate 1112 applies a forward horizontal thrust to the glass stack 0001, the bottom and rear of the entire glass transfer frame 0000 are stabilized by the constraint mechanism formed by the gripper 1210 and the base assembly 1000, thus completely eliminating the risk of the glass transfer frame 0000 tipping over.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
