Description

Technical Field

[0001] This utility model relates to the field of metal sheet processing equipment, and in particular to an automated production device for tower trays. Background Technology

[0002] Trays are key internal components in chemical equipment such as distillation columns and absorption columns, and their manufacturing quality directly affects the efficiency of gas-liquid mass transfer separation. Traditional tray production methods typically rely on multiple independent processing stations, such as separate uncoilers, shearing machines, punch presses, bending machines, and welding stations. Material transfer between these stations mostly depends on manual or semi-automatic handling equipment.

[0003] This segmented production model has significant drawbacks. First, production efficiency is severely constrained by the speed of material flow between processes. Manual handling is not only time-consuming and labor-intensive, but also prone to equipment idleness due to waiting and handover issues, resulting in an inconsistent overall production rhythm and difficulty in meeting the demands of large-scale, fast-paced production. Second, during repeated handling and repositioning, the plates are prone to scratches, bumps, or positioning errors. These accumulated errors directly affect the final processing accuracy and product quality of the trays. Furthermore, the entire production process requires a large investment of manpower, increasing labor costs for enterprises and posing potential safety risks to operators in potentially dangerous processes such as stamping and bending. Therefore, developing a production line that can efficiently integrate all aspects of tray production and achieve full-process automation has become a pressing technical problem for the industry.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by setting up a feeding mechanism, a fixing mechanism, and an anti-loosening mechanism in a coordinated manner, the steel coil feeding process is automated and highly stable. The feeding mechanism uses the combined motion of electric slide rails and cylinders to automatically lift and precisely position the steel coil; the fixing mechanism uses a hydraulically driven linkage clamping structure to achieve rapid automatic centering and firm clamping of the inner hole of the steel coil; at the same time, the pressure roller of the anti-loosening mechanism applies controllable pressure to the outer edge of the steel coil. The linkage of the three mechanisms effectively solves the problems of low efficiency, difficult positioning, and poor safety of traditional manual feeding, and provides a stable and reliable raw material supply for the entire production line.

[0015] 2. In this utility model, by setting up the sequential linkage of the uncoiling and leveling mechanism, the flipping mechanism, and the integrated grinding and leveling machine, the processing quality and process integrity of the sheet metal are improved. The uncoiling and leveling mechanism, utilizing multiple sets of staggered leveling rollers and one-way bearings, can not only effectively eliminate internal stress in the coiled material and ensure the flatness of the sheet metal, but also prevent the sheet metal from springing back and ensure feeding accuracy. The flipping mechanism solves the limitation of single-sided processing of the sheet metal, enabling the subsequent integrated grinding and leveling machine to deburr and finely level the back side of the laser-cut sheet metal, thereby ensuring the double-sided quality of the final finished workpiece and making the process flow more complete.

[0016] 3. In this utility model, articulated robots are used to connect the end processes of the production line, and safety fences are set up to construct an automated and safe production closed loop, which greatly improves production efficiency and safety. After the workpiece completes its pre-processing, the articulated robots seamlessly connect multiple key processes such as bending, nut spot welding, and finished product stacking, replacing heavy and repetitive manual handling and loading / unloading operations, realizing unmanned production processes. At the same time, the safety fences effectively isolate moving equipment from personnel, avoiding potential safety accidents, ensuring the safety of personnel while the entire production line operates efficiently and continuously.

[0019] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-8 This utility model provides an embodiment of an automated tray production device, comprising two sets of conveyor belts 1. The unloading end of each conveyor belt 1 is equipped with a housing 2, a fixing mechanism 3, an anti-loosening mechanism 4, and a feeding mechanism 5. These four parts together constitute the feeding unit of the production line, used to store steel coils, securely and stably clamp them, prevent sudden loosening of the coils during uncoiling, and accurately transport the steel coils to the unloading position, providing a stable and reliable raw material supply for subsequent continuous processing. The top of each conveyor belt 1 is sequentially equipped with an uncoiling and flattening mechanism 6, a laser cutting mechanism 7, and a grinding and flattening integrated machine 9. These three are the main sheet metal processing steps. The uncoiling and flattening mechanism 6 is used to unwind the coil and eliminate internal stress; the laser cutting mechanism 7 is used for high-precision graphic cutting; and the grinding and flattening integrated machine 9 is used to remove cutting burrs and further improve the flatness of the sheet metal. The three work together sequentially to complete the initial processing from raw materials to semi-finished products. The conveyor belt 1 is internally equipped with a turning mechanism 8 for turning the material over. The turning mechanism 8 is used for... The laser-cut sheet metal is flipped 180 degrees to allow the grinding and flattening machine 9 to process the other side of the sheet metal, ensuring the quality of both sides of the workpiece. A bending machine 10 is installed on one side of the discharge end of the conveyor belt 1, and an articulated robot 13 is installed on the other side of the discharge end of the conveyor belt 1. A nut spot welding device 11 is installed at the end of the conveyor belt 1. These three parts constitute the forming and assembly unit of the production line. The articulated robot 13 is used to perform high-precision gripping and transfer of workpieces between these workstations, realizing unmanned operation of bending forming and nut welding. A safety fence 12 is installed outside the conveyor belt 1 to physically isolate the automated operation area from the personnel activity area, thereby effectively preventing the safety risks caused by personnel accidentally entering and ensuring the safety of production. The conveyor belt 1 is used to realize the automated transportation of materials between various processing workstations, thereby connecting independent processing units into a continuous production line, reducing the need for manual handling and improving the continuity of the production cycle.

[0021] The chassis 2 is the core control and support platform of this automated production line. It integrates an industrial computer, a programmable logic controller (PLC), servo drivers, electrical components, and a human-machine interface (HMI). The chassis 2 uses its internal PLC as the main controller to receive production instructions and parameter settings from the HMI. Based on preset control logic, it sends control signals and motion commands to various devices on the production line. The PLC in chassis 2 communicates at high speed with the servo drivers and I / O modules of each substation via the industrial Ethernet protocol. For example, after the operator selects a product model on the HMI, the control system in chassis 2 calls the corresponding processing program, automatically sending material length and speed commands to the servo motor of the feeding mechanism 5, sending clamping or releasing signals to the hydraulic system of the fixing mechanism 3, and transmitting cutting graphic data to the laser cutting mechanism 7. Simultaneously, it is also responsible for receiving feedback signals from various sensors, achieving closed-loop control and fault diagnosis of the production process. By centralizing all control units inside chassis 2 for unified management and scheduling, the entire production line is centrally controlled, information is exchanged, and collaborative operations are achieved, ensuring precise matching of cycle times between each process and a high degree of automation in the production process.

[0022] The fixing mechanism 3 includes a sleeve 301 and a fixing frame 302. The side wall of the fixing frame 302 is welded to the side wall of the housing 2. A hydraulic rod 303 is installed on the side wall of the fixing frame 302. The hydraulic rod 303 is a standard hydraulic actuator used to output a strong and stable linear thrust, providing a power source for the clamping and releasing actions of the fixing mechanism 3. This is existing technology and will not be described in detail here. The output end of the hydraulic rod 303 passes through the fixing frame 302 and is fixedly connected to a slide rod 305. The side wall of the slide rod 305 is slidably connected to the inside of the sleeve 301. The sleeve 301 cooperates with the slide rod 305 to perform linear reciprocating motion, playing a guiding and supporting role, ensuring that the slide rod 305 can move stably along the axial direction under the drive of the hydraulic rod 303. A fixing rod 304 is fixedly connected inside the sleeve 301. One end of the slide rod 305 is slidably connected to the side wall of the fixing rod 304. A first fixing block 306 is fixedly connected to the side wall of the 05, and a second fixing block 307 is fixedly connected to the side wall of the fixing rod 304. A rotating plate 309 is rotatably connected to the side wall of the first fixing block 306, and a clamping plate 308 is rotatably connected to the side wall of the second fixing block 307. A support frame 310 is slidably connected inside the sleeve 301, and a rotating roller 311 is rotatably connected inside the support frame 310. The first fixing block 306 and the second fixing block 307 are arranged in a circular array. The clamping plate 308 and the rotating plate 309 are rotatably connected and staggered. When the hydraulic rod 303 pushes the slide rod 305 to move, it will drive the first fixing block 306 to move. Due to the staggered rotatable connection between the rotating plate 309 and the clamping plate 308, the movement of the first fixing block 306 will force the clamping plate 308 to contract towards the center or expand outward, thereby realizing the automatic centering and clamping function for steel coils with different inner diameters, achieving a fast and stable fixing effect. Meanwhile, the roller 311 is used to support the weight of the steel coil and can rotate freely through the internal bearing structure, thereby reducing frictional resistance during uncoiling and ensuring the smoothness of the feeding process.

[0023] The anti-loosening mechanism 4 is located on the front side of the fixing mechanism 3, including a bending plate 406 and a pressure roller 411. A base 401 is located on the front side of the fixing mechanism 3. A mounting bracket 402 is fixedly connected to the top of the base 401. A connecting seat 1 403 and a connecting seat 2 404 are mounted on the top of the mounting bracket 402. A mounting shaft 405 is rotatably connected inside the connecting seat 1 403. A torsion spring 410 is connected between the connecting seat 2 404 and the mounting shaft 405. The torsion spring 410 provides a preload force, so that the pressure roller 411 can gently press against the outer wall of the steel coil in the initial state. This effectively prevents the steel coil from suddenly loosening and springing open due to the release of residual stress at the moment the packaging tape is cut, thus playing a preliminary limiting safety role. The bending plate 406 is fixedly connected to the side wall of the mounting shaft 405. The pressure roller 411 is rotatably connected inside the bending plate 406. A motor 408 is fixedly connected to the side wall of the machine housing 2. A connecting rod 407 is fixedly connected to the output end of the motor 408. The connecting rod 407 is fixedly connected to the mounting shaft 405. The connecting rod 407 swings in coordination with the motor 408, thereby converting the rotational motion of the motor into the reciprocating rotation of the mounting shaft 405, achieving the effect of driving the pressure roller 411 to lift or press down. A support plate 409 is rotatably connected to the side wall of the connecting rod 407. The lower surface of the support plate 409 is fixedly connected to the upper surface of the base 401. The motor 408 can drive the pressure roller 411 to actively press down, applying controllable pressure to the steel coil, ensuring that the coil will not become excessively loose due to inertia during high-speed feeding, thus ensuring the stability of uncoiling.

[0024] The feeding mechanism 5 and the fixing mechanism 3 are located on the same side. The feeding mechanism includes an electric slide rail 501 and a sliding block 502 that slides with it. The electric slide rail 501 and the sliding block 502 are typically composed of high-precision guide rails, ball screws, and servo motors, used to achieve precise horizontal positioning and rapid movement of the sliding block 502. This is existing technology and will not be described in detail here. The electric slide rail 501 is laid at the bottom of the fixing mechanism 3. A cylinder 503 is installed on the top of the sliding block 502. The cylinder 503 is a standard pneumatic component used to provide vertical lifting power. This is existing technology and will not be described in detail here. A material support plate 504 is fixedly connected to the output end of the cylinder 503, and a rubber pad 505 is fixedly connected to the upper surface of the material support plate 504. Rubber pad 505 is used to increase the friction between the support plate 504 and the steel coil, and at the same time protects the surface of the steel coil from scratches, thereby achieving a stable, non-slip, and damage-free effect during lifting and transportation, reducing the loss of raw materials. An electric feeding frame 506 for transporting steel coils is provided on one side of the support plate 504. The electric feeding frame 506 works in conjunction with the electric slide rail 501 and the cylinder 503. After the electric feeding frame 506 transports the steel coil to the designated position, the electric slide rail 501 drives the support plate 504 to move directly under the steel coil. Then, the cylinder 503 lifts the support plate 504 to lift the steel coil, and the electric slide rail 501 moves it to the center position of the fixing mechanism 3, achieving the effect of automatic feeding of steel coils.

[0025] The unwinding and leveling mechanism 6 includes a slide rail 601 and two sets of sliders 602. A work plate 610 is fixedly connected between the slide rails 601. The slide rails 601 are fixedly connected to the top of the frame. One set of sliders 602 is slidably connected to the side wall of the slide rail 601, and the other set of sliders 602 is fixedly connected to the side wall of the slide rail 601. One-way bearings 603 are provided on opposite sides of each slider 602. The one-way bearings 603 of the two sets of sliders 602 rotate in opposite directions. One set of one-way bearings 603 cooperates with the leveling roller 605 to rotate in the same direction. For forward conveying of the sheet metal, another set of one-way bearings 603 rotating in the opposite direction serves to prevent backflow, ensuring that the sheet metal can only move forward in one direction, thereby avoiding springback and dimensional errors during the feeding process and ensuring feeding accuracy. The one-way bearings 603 installed inside the sliding slider 602 rotate in the opposite direction to the transmission direction of the conveyor belt 1. A rotating shaft 604 is fixedly connected between the inner rings of the same set of one-way bearings 603. A leveling roller 605 is fixedly connected to the side wall of the rotating shaft 604. The leveling roller 605 is composed of... Made of high-hardness wear-resistant alloy steel, its staggered structure, combined with the unidirectional feeding function of the one-way bearing 603, is used to repeatedly bend the uncoiled sheet material, thereby eliminating residual stress inside the material and achieving a leveling effect, improving the flatness of the sheet material. The uncoiling and leveling mechanism 6 is externally covered with a shielding frame 609, which is fixedly connected to the side wall of the conveyor belt 1 frame. A side plate 606 is fixedly connected to the side wall of the sliding slider 602, and a mounting plate 60 is fixedly connected to the side wall of the side slide 601. 7. A hydraulic rod 608 is installed inside the mounting plate 607. The output end of the hydraulic rod 608 is fixedly connected to the side plate 606. By starting the hydraulic rod 608, the slider 602 connected to it is driven to move. During the movement, the leveling roller 605 on this side moves on the surface of the steel coil. Then, the slider 602 is reset by the hydraulic rod 608. During the reset process, the leveling roller 605 is pressed on the surface of the steel coil under the restriction of the one-way bearing 603 to avoid the force generated by friction causing the steel coil to curl.

[0026] The flipping mechanism 8 includes a connecting frame 801 and a rotating roller 802. The connecting frame 801 is fixedly connected between two sets of conveyor belts 1, and the rotating roller 802 is rotatably connected between the connecting frames 801. A second motor 803 is fixedly connected to the side wall of one side of the connecting frame 801. The output end of the second motor 803 is fixedly connected to one end of the rotating roller 802. The second motor 803 is a servo motor with a reducer, which is used to provide controllable rotational power and torque for the rotating roller 802. This is existing technology and will not be described in detail here. Multiple sets of horizontal plates 804 and inclined plates 805 are fixedly connected to the side wall of the rotating roller 802. A gravity sensor is embedded in the horizontal plate 804 to sense whether the material has moved above the horizontal plate 804. When the material moves into position, the second motor 803 starts the rotating roller 802 to rotate, which drives the horizontal plates 804 and inclined plates 805 on the roller to hook the workpiece and flip it 180 degrees. Then, it is placed smoothly on the next section of the conveyor belt, achieving a fast and automatic flipping effect.

[0027] The operation process of this utility model automated tray production device includes the following steps: S1: Loading and fixing First, the operator uses a crane or other equipment to place the steel coil to be processed onto the electric feeding frame 506 of the feeding mechanism 5. After the electric feeding frame 506 transports the steel coil to the designated work position, the feeding mechanism 5 starts working. The electric slide rail 501 at its bottom drives the slide block 502 to move, causing the material support plate 504 at the top of the cylinder 503 to move directly under the steel coil. Then, the piston rod of the cylinder 503 extends, lifting the material support plate 504 and lifting the steel coil. At this time, the electric slide rail 501 starts again, transporting the slide block 502 holding the steel coil. The steel coil is positioned at the bottom of the fixing mechanism 3, and is thus fitted onto the outside of the fixing mechanism 3. At this point, the hydraulic rod 303 of the fixing mechanism 3 is activated, and its output end pushes the slide rod 305 to move inward along the sleeve 301. The slide rod 305 drives the first fixing block 306 to move, and under the combined action of the rotating plate 309 and the clamping plate 308, the clamping plate 308 and the rotating plate 309, which are arranged in a ring, are forced to contract synchronously towards the center, thereby pushing the support frame 310 outward and causing the rotating roller 311 to abut against the inner wall of the steel coil, achieving centering and clamping fixation. At the same time, the motor 408 of the anti-loosening mechanism 4 is activated, and drives the mounting shaft 405 to rotate through the connecting rod 407, causing the pressure roller 411 to press down on the outer edge of the steel coil, applying a pre-tightening pressure to prevent the steel coil from suddenly springing open and loosening when the packaging tape is cut later.

[0028] S2: Unwinding, Leveling, and Transporting After the steel coil is fixed, the conveyor belt 1 is started, and the steel coil head is introduced into the uncoiling and leveling mechanism 6. Under the traction of the conveyor belt 1, the steel coil begins to uncoil. The sheet passes through the bottom of multiple sets of counter-arranged leveling rollers 605 in sequence. When the sheet passes through the staggered leveling rollers 605, it will undergo repeated plastic bending deformation, thereby effectively eliminating the internal stress generated by the steel coil during the winding process, so that the sheet can be restored to flatness. During this process, a set of one-way bearings 603 ensures that the sheet can only be conveyed forward, while another set of counter-arranged one-way bearings 603 plays the role of preventing the sheet from springing back, ensuring the stability of the feeding. After being processed by the uncoiling and leveling mechanism 6, the original coil material becomes a flat sheet material, which is then steadily conveyed forward by the conveyor belt 1.

[0029] S3: Laser cutting After the flat plate moves along the conveyor belt 1 to the bottom of the laser cutting mechanism 7, the laser cutting mechanism 7 performs non-contact cutting on the moving or stationary plate according to the preset program, cutting out the outer contour and internal holes of the tray workpiece according to the drawing requirements, forming a semi-finished workpiece.

[0030] S4: Workpiece flipping The cut workpiece continues to be conveyed forward with the conveyor belt 1 until it reaches the flipping mechanism 8 located between the two conveyor belts 1. When the gravity sensor detects that the workpiece is in place, the motor 803 starts and drives the rotating roller 802 to rotate 180 degrees. The horizontal plate 804 and the inclined plate 805 on the side wall of the rotating roller 802 work together to hook the workpiece from the front conveyor belt 1, flip it, and then slide it onto the rear conveyor belt 1.

[0031] S5: Gripping, Bending and Spot Welding After being flipped, the workpiece first passes through a grinding and leveling machine 9 to remove slag generated during laser cutting and perform secondary fine leveling. Then, the workpiece is conveyed to the discharge end of conveyor belt 1. At this point, an articulated robot 13 located on one side starts, and its end gripper precisely grasps the workpiece. The articulated robot 13 first transports the workpiece to the bending machine 10, where it works in conjunction with the bending machine 10 to complete the predetermined bending and forming process. After bending, the articulated robot 13 again grasps the formed workpiece and places it on the worktable of the nut spot welding device 11. The nut spot welding device 11 automatically feeds the nut and performs efficient spot welding, firmly welding the nut to the designated position on the workpiece.

[0032] S6: Finished Product Stacking Once all the nut spot welding is completed, the articulated robot 13 grabs the finished tower tray for the last time and neatly stacks it onto the designated product rack or the AGV trolley for the next process according to the preset stacking method. At this point, the entire tower tray production is completed.
