Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy ingot stacking devices, specifically an aluminum alloy ingot flipping and clamping device. Background Technology

[0002] The stacking of aluminum alloy ingots requires a combination of automation technology and safety regulations. It is mainly divided into two methods: manual and mechanical. When stacking manually, it is necessary to ensure that the aluminum ingots are cooled before operation, the stacking layer does not exceed 11 layers, and double hook tools are used to ensure stability. At the same time, protective equipment should be worn to avoid burns.

[0003] Currently, aluminum alloy ingots require stacking during production. Traditional aluminum alloy ingots have two sides and a trapezoidal cross-section. During stacking, alternating sides for each layer helps reduce the space occupied. However, in actual stacking, operators need to place the aluminum alloy ingots on a conveyor belt, and then use a robotic arm to clamp and flip them, with each layer of ingots placed alternately. This results in poor stacking convenience and low efficiency, mainly because the stacking efficiency is limited by the operating speed of the robotic arm. Therefore, the inventor urgently needs to design a flipping and clamping mechanism for aluminum alloy ingots to improve the convenience and efficiency of stacking. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an aluminum alloy ingot flipping and clamping device to solve the technical problems of low flipping efficiency and poor convenience during the stacking of aluminum alloy ingots.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum alloy ingot flipping and clamping device, comprising... A conveyor chain, which is mounted on a support frame via a motor drive; A flipping mechanism, comprising a flipping plate, one side of which is hinged to a support frame, and the other side of which is hinged to a first pneumatic push rod for flipping aluminum alloy ingots; A limiting mechanism, the limiting mechanism including an adjusting plate, a limiting plate adjustablely disposed above the adjusting plate, and a second pneumatic push rod installed between the adjusting plate and the support frame below the adjusting plate; A baffle is used to limit the maximum displacement of an aluminum alloy ingot. A visual recognition system, the visual recognition system including a mounting bracket and a visual camera; The clamping mechanism includes two sets of movable plates. Two parallel connecting rods are hinged between the lower part of the movable plates and the support frame. A hydraulic rod is hinged to one side of one of the connecting rods. The two sets of movable plates are mirror images of each other on both sides of the flipping clamping device. A clamping plate is installed on the inner side of the movable plates via a third pneumatic push rod. A scissor lift, wherein the scissor lift is located at the transport end of two sets of tilting clamping devices, and a stacking base plate is placed above the scissor lift; A height detection system, comprising a mounting rod and an infrared sensor, is used to detect the height of the uppermost aluminum alloy ingot located above the stacking base plate.

[0006] By adopting the above technical solution and through integrated multi-mechanism collaborative design, the entire process of aluminum alloy ingots from conveying to stacking is automated. The conveyor chain combined with baffles ensures that the ingot is accurately positioned to the flipping station. The vision camera automatically identifies the front and back states to trigger subsequent operations, greatly reducing the need for manual intervention. The flipping plate of the flipping mechanism is driven by the first pneumatic push rod to complete the flipping, which is suitable for the requirements of trapezoidal cross-sections for alternating front and back stacking.

[0007] Furthermore, the surface of the flip plate is provided with fine friction texture.

[0008] By adopting the above technical solution, the friction of the contact surface is increased, which effectively prevents the aluminum alloy ingot from sliding or tipping over during the flipping process. Especially for aluminum ingots with smooth surfaces, this structure can offset the risk of displacement caused by inertia when the first air push rod drives the flipping.

[0009] Furthermore, both the limiting plate and the adjusting plate are provided with two sets of straight grooves, and the limiting plate and the adjusting plate are adjustable by bolts and straight grooves.

[0010] By adopting the above technical solution, the straight groove adjustable structure of the limiting plate and the adjusting plate can flexibly adjust the limiting height with bolts to adapt to the thickness difference of aluminum alloy ingots of different specifications. When the second air pusher pushes the adjusting plate up and down, this setting can accommodate dimensional fluctuations within the tolerance range.

[0011] Furthermore, the shooting axis of the visual camera is opposite to the longitudinal position of the flip plate, and is used to detect the front and back states of the aluminum alloy ingot.

[0012] By adopting the above technical solution, the axial alignment of the vision camera with the flip plate ensures that the captured image covers the entire surface of the aluminum alloy ingot before it is flipped. By directly identifying the front and back states, the flipping mechanism's action decision is accurately triggered.

[0013] Furthermore, the movable plate, the two sets of connecting rods, and the support frame are in the form of a parallelogram hinge structure, and the movable plates and clamping plates on both sides move synchronously.

[0014] By adopting the above technical solution, the parallelogram hinge structure of the movable plate, connecting rod and support frame ensures that the clamping units on both sides maintain absolute synchronous movement under the drive of the hydraulic rod, ensuring that the aluminum alloy ingot is subjected to balanced force. When the clamping action is triggered, the clamping force on both sides of the ingot is always symmetrical, avoiding skewing or falling off caused by unilateral squeezing.

[0015] Furthermore, the infrared sensor is pre-installed at any height position on the mounting rod.

[0016] By adopting the above technical solution, the infrared sensor is designed with an adjustable height on the mounting rod, allowing for flexible setting of the detection benchmark according to the expected number of stacking layers. By presetting different height thresholds, it can dynamically adapt to the stacking status monitoring needs from single layer to full stack.

[0017] Furthermore, the first, second, and third pneumatic actuators are all connected to an external air source via solenoid valves, and the solenoid valves, scissor lift, infrared sensor, and vision camera are all electrically connected to an external power source via a controller.

[0018] By adopting the above technical solution, the pneumatic actuator is supplied with air centrally through a solenoid valve, and combined with the unified scheduling and execution logic of the controller, it can achieve millisecond-level coordinated response of flipping, limiting, and clamping actions.

[0019] In summary, the present invention has the following main advantages: This invention achieves precise positioning of aluminum alloy ingots through the cooperation of a conveyor chain and a baffle. Simultaneously, a visual camera automatically identifies the front and back of the ingot, providing a basis for decision-making during the flipping operation and reducing the need for manual intervention. Secondly, the flipping plate of the flipping mechanism is driven by a first pneumatic push rod to complete the flipping, adapting to the staggered stacking rules of the trapezoidal cross-section. Subsequently, the hydraulic rod of the clamping mechanism drives the connecting rod, causing the movable plate to retract synchronously along a parallelogram trajectory. At the same time, a third pneumatic push rod controls the clamping plate to apply a balanced clamping force, ensuring transfer stability. Finally, a scissor lift receives the clamped ingots and stacks them on the stacking base plate. Meanwhile, an infrared sensor monitors the stacking status in real time at a preset height on the mounting rod, forming a closed-loop height feedback control for the lifting action. Compared to the clamping, flipping, and stacking operations of a robotic arm, this invention further improves the stacking efficiency of aluminum alloy ingots. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In this embodiment: Aluminum alloy ingot flipping and clamping device, such as Figure 1-4 As shown, including Conveyor chain 1 is mounted on a support frame via a motor drive; The flipping mechanism 2 includes a flipping plate 201, one side of which is hinged to a support frame, and the other side of which is hinged to a first pneumatic push rod 202 for flipping aluminum alloy ingots. The limiting mechanism 3 includes an adjusting plate 302, a limiting plate 301 is adjustablely provided above the adjusting plate 302, and a second pneumatic push rod 303 is installed between the adjusting plate 302 and the support frame below the adjusting plate 302. Baffle 4 is used to limit the maximum displacement of the aluminum alloy ingot; A visual recognition system, comprising a mounting bracket 10 and a visual camera 11; The clamping mechanism 5 includes two sets of movable plates 501. Two parallel connecting rods 502 are hinged between the lower part of the movable plate 501 and the support frame. A hydraulic rod 505 is hinged to one side of one of the connecting rods 502. The two sets of movable plates 501 are mirror images of each other on both sides of the flipping clamping device. The clamping plate is installed on the inner side of the movable plate 501 via a third pneumatic push rod 504. The scissor lift 6 is located at the end of the transport of the two sets of tilting clamping devices, and a stacking base plate 7 is placed on top of the scissor lift 6. The height detection system, comprising mounting rod 8 and infrared sensor 9, is used to detect the height of the top aluminum alloy ingot located above the stacking base plate 7. Through integrated multi-mechanism collaborative design, the entire process from conveying to stacking of aluminum alloy ingots is automated. The conveyor chain 1, combined with baffle 4, ensures that the ingot is accurately positioned to the flipping station. The vision camera 11 automatically identifies the front and back states to trigger subsequent operations, significantly reducing the need for manual intervention. The flipping plate 201 of the flipping mechanism 2 is driven by the first pneumatic push rod 202 to complete the flipping, adapting to the requirements of trapezoidal cross-section for alternating front and back stacking. At the same time, the parallelogram hinge structure of the clamping mechanism 5 is linked by hydraulic rod 505, combined with the third pneumatic push rod 504 to control the clamping plate to clamp the ingot synchronously, avoiding deviation during flipping or transfer. The scissor lift 6 works in conjunction with the infrared sensor 9 of the height detection system to dynamically monitor the stacking height of the stacking base plate 7, realizing automated adjustment of layered stacking. The entire system is seamlessly connected through pneumatic, hydraulic and sensor control, significantly improving stacking efficiency and stability.

[0024] See Figure 1 , Figure 2 , Figure 4 The surface of the flip plate 201 is provided with fine friction texture. By increasing the friction of the contact surface, it effectively prevents the aluminum alloy ingot from sliding or tipping over during the flipping process. Especially for aluminum ingots with smooth surfaces, this structure can offset the risk of displacement caused by inertia when the first air push rod 202 drives the flipping. At the same time, the friction texture is distributed in the form of fine grooves to avoid damage to the surface of the aluminum ingot due to excessive roughness. While ensuring the stability of the flipping, it also takes into account the integrity of the product and reduces the quality degradation caused by surface scratches.

[0025] See Figure 1 , Figure 2 , Figure 4 Both the limiting plate 301 and the adjusting plate 302 are provided with two sets of straight grooves. The limiting plate 301 and the adjusting plate 302 are adjustable by bolts and straight grooves. The adjustable structure of the straight grooves of the limiting plate 301 and the adjusting plate 302 allows for flexible adjustment of the limiting height by bolts to adapt to the thickness differences of aluminum alloy ingots of different specifications. When the second pneumatic push rod 303 pushes the adjusting plate up and down, this setting can accommodate dimensional fluctuations within the tolerance range. At the same time, the longitudinal slotting form of the straight groove allows the limiting plate to be quickly adjusted and locked, avoiding the production line stagnation problem caused by changes in the size of aluminum ingots in traditional fixed limiting devices, and significantly improving the equipment versatility and production line flexibility.

[0026] See Figure 1 , Figure 2The shooting axis of the vision camera 11 is opposite to the longitudinal position of the flip plate 201, and is used to detect the front and back states of the aluminum alloy ingot. The setting of the vision camera 11 aligning with the flip plate 201 ensures that the captured image covers the complete surface of the aluminum alloy ingot before flipping. By directly identifying the front and back states, the flipping mechanism 2 is accurately triggered to make action decisions. At the same time, this axial positioning avoids misjudgment caused by shooting angle deviation. Especially for reflective metal surfaces, it can reduce the impact of ambient light interference on the recognition accuracy and provide reliable data support for subsequent flipping and clamping.

[0027] See Figure 1 , Figure 2 , Figure 3 The movable plate 501, two sets of connecting rods 502, and the support frame are in a parallelogram hinge structure. The movable plates 501 and clamping plates 503 on both sides move synchronously. The parallelogram hinge structure of the movable plate 501, connecting rods 502 and support frame ensures that the clamping units on both sides maintain absolute synchronous movement under the drive of the hydraulic rod 505, ensuring that the aluminum alloy ingot is subjected to balanced force. When the clamping action is triggered, the clamping force on both sides of the ingot is always symmetrical, avoiding skewing or falling off caused by unilateral squeezing. At the same time, the rigid trajectory constraint of the parallelogram structure improves the clamping positioning accuracy.

[0028] See Figure 1 The infrared sensor 9 is pre-installed at any height on the mounting rod 8. The height of the infrared sensor 9 on the mounting rod 8 is arbitrarily adjustable, allowing the detection benchmark to be flexibly set according to the expected number of stacking layers. By pre-setting different height thresholds, it can dynamically adapt to the stacking status monitoring needs from single layer to full stack. At the same time, this adjustability solves the problem of false alarms caused by differences in aluminum ingot thickness or bottom plate settlement, ensuring that the lifting action of the scissor lift 6 strictly responds to the actual stacking height changes.

[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The first pneumatic actuator 202, the second pneumatic actuator 303, and the third pneumatic actuator 504 are all connected to an external air source via solenoid valves. The solenoid valves, scissor lift, infrared sensor 9, and vision camera 11 are all electrically connected to an external power source via a controller. The pneumatic actuators are centrally supplied with air through the solenoid valves. Combined with the unified scheduling and execution logic of the controller, millisecond-level coordinated responses to flipping, limiting, and clamping actions are achieved. At the same time, the electrical signals of the vision camera 11, infrared sensor 9, and scissor lift 6 are integrated and processed by the controller to construct a closed-loop control system: for example, visual recognition results trigger flipping, and infrared height feedback regulates the lift, forming a fully unmanned operation chain and eliminating efficiency bottlenecks caused by delays due to manual operation.

[0030] The implementation principle of this embodiment is as follows: The aluminum alloy ingot is first conveyed to the working position by the conveyor chain 1, and the baffle 4 restricts its displacement endpoint; at this time, the vision camera 11 identifies the front and back of the ingot, and at the same time, the second pneumatic push rod 303 of the limiting mechanism 3 pushes the height of the adjusting plate 302 and the limiting plate 301 to center and position the ingot. Subsequently, the flipping mechanism 2 is activated: the first pneumatic push rod 202 drives the flipping plate 201 to rotate around the hinge point, completing the front and back of the ingot. Then, the clamping mechanism 5 is activated: the hydraulic rod 505 pushes and pulls the connecting rod 502, which in turn moves the mirrored moving parts on both sides. The moving plate 501 moves inward synchronously along the parallelogram trajectory, and the clamping plate 503 is pushed by the third pneumatic push rod 504 to clamp the spindle. The clamped spindle is then transferred to the end scissor lift 6 and stacked on the stacking base plate 7. The height detection system monitors the stacking height in real time through the infrared sensor 9 preset on the mounting rod 8. The feedback signal controls the scissor lift to descend layer by layer. The entire process is automated and cyclical, achieved by the controller in coordination with pneumatic components and sensors. The core is to ensure accurate flipping, stable clamping, and efficient layered stacking through the integration of mechanical structure linkage and sensor feedback.
