After the stamping equipment completes the processing of a single aluminum plate, it is necessary to wait for manual stacking and sorting of the plates before continuing to unload. This causes the stamping equipment to start and stop frequently, resulting in serious interruption of the production rhythm, making it difficult to form continuous operation between the stamping process and subsequent processing stations, greatly reducing the overall efficiency of the production line.

DETAILED DESCRIPTION

[0031] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0032] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0033] In the description of the present invention, "several" means an indefinite quantity, "multiple" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, and "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" is solely for the purpose of distinguishing technical features and should not be understood to indicate or imply relative importance, or to implicitly indicate the number or order of the technical features indicated. "And / or" throughout the text represents three parallel solutions. For example, "A and / or B" means a solution where A satisfies, a solution where B satisfies, or a solution where both A and B satisfy.

[0036] The following combination Figures 1 to 4 Embodiments of the present invention are described.

[0037] A blanking device in this embodiment includes:

[0038] Rack 100;

[0039] A conveying mechanism, which is provided on the frame 100 and is used to transport materials;

[0040] A stacking mechanism is provided on the frame 100, wherein the material receiving surface of the stacking mechanism is provided at the conveying end of the conveying mechanism; the stacking mechanism is capable of adjusting the height of its material receiving surface so that the upper surface of each stacked material remains flush with the conveying surface of the conveying mechanism;

[0041] A picking mechanism is provided on the frame 100 and is located above the stacking mechanism; the picking mechanism moves horizontally and vertically along the horizontal and vertical directions of the frame 100; the picking mechanism is used to pick up materials stacked on the stacking mechanism.

[0042] In the unloading device of the present invention, the frame 100 serves as the basic supporting structure of the entire unloading device, providing a platform for installation and fixing of other mechanisms; the conveying mechanism is installed on the frame 100, and its power source drives the conveying components to operate, transferring the material from the starting position to the conveying end side; the stacking mechanism is also arranged on the frame 100, and its supporting surface is located at the conveying end side of the conveying mechanism; when the material is transported to the supporting surface of the stacking mechanism for stacking, the stacking mechanism adjusts the height of the supporting surface to ensure that the upper surface of each newly stacked material remains flush with the conveying surface of the conveying mechanism, so that subsequent materials can smoothly transition from the conveying mechanism to the stacking mechanism; the picking mechanism is arranged on the frame 100 and is located above the stacking mechanism. When the material on the stacking mechanism is stacked to a certain amount or reaches a specific state, the picking mechanism moves to the designated position, picks up the stacked material, and then transfers the material to a subsequent processing or storage position. The unloading device of the present invention can realize the whole process connection of materials from transmission, dynamic height matching stacking to automatic picking without human intervention through the cooperation of the above-mentioned mechanisms, solving the problems of frequent start and stop of stamping equipment, interruption of production rhythm and inefficient process connection caused by traditional manual unloading, significantly improving the continuous operation efficiency of the production line, reducing labor costs and operational risks, and meeting the needs of modern and efficient production.

[0043] Specifically, the conveying mechanism includes a first connecting member 210, an active belt roller 220, a driven belt roller 230, a conveying belt 240 and a first driving motor 250; the first connecting member 210 is arranged on the frame 100, the active belt roller 220 and the driven belt roller 230 are arranged on the first connecting member 210, and the active belt roller 220 and the driven belt roller 230 are rotatably connected to the first connecting member 210; the first driving motor 250 is transmission-connected to the active belt roller 220, and the conveying belt 240 is wound between the active belt roller 220 and the driven belt roller 230.

[0044] The active belt roller 220 and the driven belt roller 230 can rotate on the first connecting member 210 to provide support for the operation of the conveyor belt 240. The first drive motor 250 is connected to the active belt roller 220 for transmission. When the unloading device starts working, the first drive motor 250 is started, and the power of the first drive motor 250 is transmitted to the active belt roller 220, causing it to start rotating. Since the conveyor belt 240 is sleeved on the active belt roller 220 and the driven belt roller 230, the rotation of the active belt roller 220 will drive the conveyor belt 240 to move, and then the driven belt roller 230 will rotate accordingly; the material to be transported is placed on the conveyor belt 240, and as the conveyor belt 240 moves, the material is transported from the conveying starting point to the conveying end of the conveying mechanism.

[0045] Specifically, the conveying mechanism also includes a bearing seat 270, an adjusting screw 280 and a knob 290; an adjusting slot 260 is opened on the first connecting member 210, and the end of the driven belt roller 230 passes through the adjusting slot 260 and is rotatably connected to the bearing seat 270, and the bearing seat 270 is slidably connected to the adjusting slot 260; a first threaded hole 211 is provided on the first connecting member 210, one end of the adjusting screw 280 passes through the first threaded hole 211 and is fixedly connected to the knob 290, and the adjusting screw 280 is threadedly connected to the first threaded hole 211; the other end of the adjusting screw 280 is provided with an anti-slip member, and the anti-slip member is fixedly connected to the bearing seat 270; by screwing the knob 290 to change the depth of the adjusting screw 280 penetrating into the first threaded hole 211, the bearing seat 270 can be driven to slide along the first connecting member 210, thereby causing the driven belt roller 230 to move along the adjusting slot 260.

[0046] When the tension and position of the conveyor belt 240 need to be adjusted, the operator can manually turn the knob 290. The knob 290 is fixedly connected to one end of the adjusting screw 280, and the adjusting screw 280 forms a threaded fit with the first threaded hole 211 on the first connecting member 210; therefore, turning the knob 290 will directly rotate the adjusting screw 280 in the first threaded hole 211, thereby changing the depth of the adjusting screw 280 penetrating into the first threaded hole 211; the other end of the adjusting screw 280 is fixedly connected to the bearing seat 270 via an anti-slip member, and the anti-slip member is used to prevent the bearing seat 270 from rotating as the screw rotates; thus, by changing the depth of the adjusting screw 280 penetrating into the first threaded hole 211, the bearing seat 270 is driven to slide along the first connecting member 210;

[0047] Because the end of the driven belt roller 230 is rotatably connected to the bearing seat 270, the sliding of the bearing seat 270 causes the driven belt roller 230 to move along the adjustment slot 260. Changes in the position of the driven belt roller 230 stretch or contract the conveyor belt 240, thereby adjusting the tension and position of the conveyor belt 240. Over long-term use, the conveyor belt 240 may become loose. By adjusting the position of the driven belt roller 230, the tension of the conveyor belt 240 can be adjusted promptly to ensure the stability of the conveying process. Furthermore, the position of the conveyor belt 240 can be fine-tuned to meet the conveying requirements of different materials, improving the applicability and flexibility of the unloading device.

[0048] Specifically, the stacking mechanism includes a lifting device and a carrying platform 320 arranged on the frame 100. The carrying platform 320 is transmission-connected to the lifting device. The lifting device drives the carrying platform 320 to perform lifting and lowering movements along the vertical direction of the frame 100. The carrying platform 320 serves as a supporting surface to receive the materials transported by the conveying mechanism.

[0049] The lifting device is installed on the frame 100 and serves as a power source for driving the vertical movement of the carrying platform 320, which can drive the carrying platform 320 to rise and fall vertically along the frame 100; the carrying platform 320 serves as a supporting surface to receive materials delivered by the conveying mechanism; as the materials are continuously stacked, the lifting device adjusts the height of the carrying platform 320 in real time based on the preset or sensor feedback, so that the upper surface of the newly stacked materials remains flush with the conveying surface of the conveying mechanism, ensuring smooth transition and stacking of materials to avoid jamming and slipping; compared with traditional manual adjustment or fixed height stacking methods, the stacking mechanism can better adapt to the stacking needs of materials of different specifications and quantities, reduce manual intervention and operating errors, and improve the degree of automation and stability of production.

[0050] Specifically, the lifting device includes a second connecting member 310, a first guide rail 330, a second drive motor 340, a screw rod 350 and a nut seat 360; the second connecting member 310 is arranged on the frame 100, the first guide rail 330 is vertically arranged on the second connecting member 310, and the two ends of the screw rod 350 are rotatably connected to the two ends of the first guide rail 330; the second drive motor 340 is arranged on the first guide rail 330; the output shaft of the second drive motor 340 is transmission-connected to the screw rod 350, and the nut seat 360 is threadedly connected to the screw rod 350; the supporting platform 320 is arranged on the nut seat 360, and the supporting platform 320 is slidingly connected to the first guide rail 330; the second drive motor 340 drives the screw rod 350 to rotate, so that the nut seat 360 rises and falls along the screw rod 350, and drives the supporting platform 320 to rise and fall along the first guide rail 330.

[0051] In this embodiment, the carrying platform 320 serves as a supporting surface, directly receiving the materials transported by the conveying mechanism; the carrying platform 320 is fixedly connected to the nut seat 360, and its side forms a sliding pair with the first guide rail 330 vertically installed on the frame 100. This structural design can ensure that the carrying platform 320 maintains good stability during the lifting process, effectively reduces shaking and offset, and enables the materials to be stacked stably on the carrying platform 320; the second drive motor 340 adopts a servo motor, which is installed at the bottom of the first guide rail 330; the output shaft of the second drive motor 340 is coaxially connected to the bottom end of the screw rod 350 through a coupling, and the top end of the screw rod 350 is connected to the second connecting member 310 through a coupling; when the second drive motor 340 is started, its power can be transmitted to the screw rod 350, thereby driving the nut seat 360 threaded with the screw rod 350 to perform linear motion, and finally realize the lifting and lowering action of the carrying platform 320;

[0052] The operating principle of the stacking mechanism is as follows: when it is in the initial state of operation, its material-bearing surface is flush with the conveying surface of the conveying mechanism, waiting to receive the first piece of material; when the conveying mechanism conveys the material to the carrying platform 320, the second drive motor 340 is started, driving the screw rod 350 to rotate, and the nut seat 360 moves downward along the screw rod 350, and slides on the first guide rail 330 through the slider, driving the carrying platform 320 to descend, so that the upper surface of the first layer of material is flush with the conveying surface of the conveying mechanism again; for each subsequent layer of material stacked, the carrying platform 320 is height-adjusted to ensure that the upper surface of each newly stacked material is always flush with the conveying surface; when the picking mechanism takes away the entire group of materials, the carrying platform 320 rises to the initial height, waiting for the next round of stacking;

[0053] Regarding the motion control method of the support platform 320, on the one hand, precise control can be performed based on real-time sensor signals. For example, a material quantity sensor, such as a through-beam photoelectric sensor, can be installed at the edge of the upper surface of the support platform 320 or at the discharge end of the conveyor mechanism. The material quantity sensor is electrically connected to the controller of the second drive motor 340, converting the detected material quantity signal into an electrical signal and feeding it back to the controller of the second drive motor 340. The controller then issues corresponding instructions to the second drive motor 340 to precisely control the lifting height of the support platform 320, ensuring that the upper surface of each newly stacked material remains flush with the conveyor surface of the conveyor mechanism. On the other hand, the lifting strategy of the support platform 320 can be preset based on the unloading frequency of the conveyor mechanism or the previous process. For example, if it is known that the conveying mechanism conveys a piece of material at fixed time intervals, then the carrying platform 320 can be pre-set to make corresponding height adjustments at the same time intervals; before the material is conveyed, the carrying platform 320 is adjusted to a suitable height in advance and waits for the arrival of the material; whether based on real-time sensor signals or preset programs, the carrying platform 320 can flexibly and accurately complete the lifting and lowering actions to meet the material stacking requirements in different production scenarios and improve the efficiency and smoothness of the entire feeding process.

[0054] Specifically, the picking mechanism includes a mobile platform and a picking device, the mobile platform is arranged on the frame 100, the picking device is arranged on the mobile platform, and the picking device is transmission-connected to the mobile platform; the mobile platform is used to drive the picking device to move horizontally and vertically along the horizontal and vertical directions of the frame 100; the picking device is used to pick up materials stacked on the stacking mechanism.

[0055] The mobile platform is installed on the frame 100, providing the picking device with driving force for moving in the horizontal and vertical directions of the frame 100; the picking device is connected to the mobile platform in a transmission manner. When the mobile platform moves in the horizontal and vertical directions according to the instructions of the control system, it will drive the picking device to the designated position of the stacking material on the stacking mechanism, and then the picking device will execute the action of picking up the material and complete the transfer of the material from the stacking mechanism to the subsequent workstation; compared with traditional manual picking, the picking mechanism can flexibly pick up materials at different positions, can adapt to production lines with different layouts and a variety of material stacking positions, and effectively improve the flexibility and versatility of the entire feeding system.

[0056] Specifically, the movable platform includes a second guide rail 410, a slide 420, a first cylinder 430 and a second cylinder 440; the second guide rail 410 is horizontally arranged on the frame 100, the slide 420 is arranged on the second guide rail 410, and the slide 420 is slidingly connected to the second guide rail 410; the first cylinder 430 is arranged at one end of the second guide rail 410, and the output end of the first cylinder 430 is transmission-connected to the slide 420; when the first cylinder 430 is extended or retracted, its output part drives the slide 420 to move horizontally along the horizontal direction of the frame 100; the second cylinder 440 is vertically arranged on the slide 420, and the output part of the second cylinder 440 is transmission-connected to the picking device, and when the second cylinder 440 is extended or retracted, its output part drives the picking device to move vertically along the vertical direction of the frame 100.

[0057] When the picking device needs to move in the horizontal direction, the piston rod of the first cylinder 430 is extended and retracted, pushing or pulling the slide 420 to move horizontally along the second guide rail 410, thereby driving the picking device to reach the specified position in the horizontal direction; when the picking device needs to move in the vertical direction, the piston rod of the second cylinder 440 is extended and retracted, driving the third connecting member 450 connected to the output part and the entire picking device to rise or fall in the vertical direction, so as to approach or leave the stacked materials; through the coordinated action of the first cylinder 430 and the second cylinder 440, the movement of the picking device in the horizontal and vertical directions is realized.

[0058] Specifically, the picking device includes a driving device, a third connecting member 450 and two sliding rails 470; the third connecting member 450 is transmission-connected to the output part of the second cylinder 440; rail grooves 460 are respectively provided at both ends of the bottom surface of the third connecting member 450, and the two sliding rails 470 are respectively arranged in the rail grooves 460, and the sliding rails 470 are slidingly connected to the rail grooves 460; each of the sliding rails 470 is provided with a clamping claw; the driving device is arranged on the third connecting member 450, and the driving device is transmission-connected to the two sliding rails 470; the driving device is used to drive the two sliding rails 470 to slide relative to each other in the rail groove 460 to adjust the distance between the two clamping claws.

[0059] In this embodiment, the driving device includes a third driving motor, a gear, a first rack and a second rack; the third driving motor is arranged on the third connecting member 450, serving as the power source of the entire driving device, and the output end of the third driving motor is coaxially connected to the gear; a first rack is provided above the gear, and a second rack is provided below the gear, and the first rack and the second rack are meshed with the gear; the first rack is connected to one of the slide rails 470, and the second rack is connected to the other slide rail 470; when it is necessary to adjust the distance between the two clamping jaws to achieve the clamping or releasing operation of the material, the third driving motor is started and drives the gear connected thereto to start rotating; since the first rack and the second rack are respectively located on the upper and lower sides of the gear and They are all meshed with gears. According to the transmission principle of gears and racks, when the gears rotate, they will drive the first rack and the second rack to make linear motion in opposite directions, thereby driving the two slide rails 470 to slide relative to each other in the track groove 460, so that the clamping claws on the two slide rails 470 gradually approach until the material is clamped; when the material needs to be released, the two slide rails 470 are driven to slide in the opposite direction, the clamping claws open, and the material is released; the cooperation between the slide rails 470 and the track groove 460 is guiding, which makes the opening and closing of the clamping claws more stable and precise, reducing the risk of shaking and falling of the material during the clamping process; the opening and closing of the clamping claws is achieved by the sliding of the slide rails 470 in the track groove 460, and the clamping and release of the material are quickly achieved, thereby improving the picking efficiency.
