Description

Technical Field

[0001] This utility model relates to a central tube fixed-angle feeding mechanism. Background Technology

[0002] Currently, in the production process of RO membranes, a welding device is needed to weld the flow guide cloth onto the central tube. For example, Chinese patent CN209666299U discloses a welding device that can weld the flow guide cloth onto the central tube using an ultrasonic welding gun. When welding the flow guide cloth and the central tube, it is necessary to avoid pointing the water outlet on the central tube directly at the ultrasonic welding gun. This is because if the water outlet is directly facing the ultrasonic welding gun, the ultrasonic welding gun will weld the flow guide cloth to the location of the water outlet on the central tube, which can cause partial blockage of the water outlet and thus affect the water output efficiency.

[0003] To ensure that the water outlet on the central tube does not face the ultrasonic welding gun, the feeding mechanism needs to feed the central tube at a fixed angle when transporting it to the welding device. This ensures that the angle of the water outlet on the central tube is offset from that of the ultrasonic welding gun. However, most existing feeding mechanisms cannot achieve this fixed-angle feeding. For example, Chinese Patent CN221070015U discloses a central tube feeding mechanism for a fully automated RO membrane roll production line. In this mechanism, a lifting cylinder first drives a lifting frame to lift a central tube in the hopper, and then a gripping robot moves the lifted central tube for feeding. However, the lifting frame cannot control the angle of the water outlet on the lifted central tube when lifting it. Therefore, when the gripping robot moves the central tube to the welding device, the angle of the water outlet on the central tube is random and uncontrollable, thus failing to achieve fixed-angle feeding. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a central tube fixed-angle feeding mechanism, which can drive the central tube to rotate to adjust the angle of the water outlet on the central tube, thereby realizing fixed-angle feeding of the central tube.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a central tube fixed angle feeding mechanism, including a frame, a hopper, a lifting bracket, a lifting drive mechanism, an angle adjustment mechanism, a detection sensor, a controller, and a handling robot;

[0006] The hopper is used to store the central tube, and the bottom of the hopper is provided with a support channel;

[0007] The lifting bracket is connected to the lifting drive mechanism, which drives the lifting bracket to rise so that the lifting bracket extends upward into the storage channel and lifts the central tube stored in the hopper.

[0008] The angle adjustment mechanism is connected to the frame and is used to clamp the central tube supported by the lifting bracket and drive the central tube to rotate.

[0009] The detection sensor is connected to the controller, and the detection sensor is used to send a signal to the controller when it detects that the central tube driven to rotate in the angle adjustment mechanism has rotated to a specified angle.

[0010] The controller is connected to the angle adjustment mechanism. After receiving the signal sent by the detection sensor, the controller controls the angle adjustment mechanism to stop driving the central tube to rotate and controls the angle adjustment mechanism to release the central tube so that the central tube is supported on the lifting bracket.

[0011] The handling robot is used to grab the central tube that has been rotated to a specified angle on the lifting bracket and move the central tube to feed the material.

[0012] Furthermore, the lifting drive mechanism includes at least one linear module, the lifting bracket is connected to the linear module, the linear module is connected to the frame and is used to drive the lifting bracket to rise so that the lifting bracket extends into the storage channel during the lifting process and lifts the central tube stored in the hopper.

[0013] Furthermore, the lifting drive mechanism includes two parallel linear modules, both of which are synchronous belt type linear modules and are connected to each other by a synchronous transmission shaft, with a drive motor connected to one of the linear modules.

[0014] Furthermore, the angle adjustment mechanism includes a first slide, a first top shaft, a second slide, a second top shaft, a clamping drive mechanism, and a rotation drive mechanism;

[0015] The first slide and the second slide are slidably connected to the frame along the axial direction of the central tube on the lifting bracket, with the first slide located on one side of the central tube on the lifting bracket and the second slide located on the other side of the central tube on the lifting bracket.

[0016] The first top shaft is rotatably connected to the first slide, and the second top shaft is rotatably connected to the second slide;

[0017] The clamping drive mechanism is connected to the frame and is connected to the first slide and the second slide respectively. The clamping drive mechanism is used to drive the first slide to move toward the central tube on the lifting bracket, thereby driving the first top shaft to press against one end of the central tube on the lifting bracket. The clamping drive mechanism is also used to drive the second slide to move toward the central tube on the lifting bracket, thereby driving the second top shaft to press against the other end of the central tube on the lifting bracket, thereby causing the first top shaft and the second top shaft to clamp the central tube on the lifting bracket.

[0018] The rotary drive mechanism is connected to the first slide and to the first top shaft, and is used to drive the first top shaft to rotate, thereby driving the central tube clamped by the first top shaft and the second top shaft to rotate.

[0019] The controller is connected to the rotary drive mechanism and the clamping drive mechanism respectively. After receiving the signal sent by the detection sensor, the controller controls the rotary drive mechanism to stop driving the first top shaft to rotate and controls the clamping drive mechanism to drive the first slide and the second slide to move away from the central tube on the lifting bracket respectively.

[0020] Furthermore, the rotary drive mechanism includes a rotary motor, a driving wheel, a driven wheel, and a transmission component;

[0021] The drive wheel is connected to the rotary motor;

[0022] The driven wheel is connected to the first top shaft;

[0023] The transmission component is connected to the driving wheel and the driven wheel;

[0024] The rotary motor is connected to the first slide and is used to drive the drive wheel to rotate, which in turn drives the driven wheel and the first top shaft to rotate through the transmission component.

[0025] Furthermore, a protective cover is connected to the first slide block to cover the outside of the driving wheel, the driven wheel, and the transmission component.

[0026] Furthermore, the clamping drive mechanism includes a first cylinder and a second cylinder;

[0027] The cylinder body of the first cylinder is connected to the frame, and the piston rod of the first cylinder is connected to the first slide. The first cylinder is used to drive the first slide to move toward or away from the central tube on the lifting bracket.

[0028] The cylinder body of the second cylinder is connected to the frame, and the piston rod of the second cylinder is connected to the second slide. The second cylinder is used to drive the second slide to move toward or away from the central tube on the lifting bracket.

[0029] The thrust of the first cylinder is different from that of the second cylinder.

[0030] Furthermore, the detection sensor is a laser sensor and is used to emit a detection beam into the central tube that is driven to rotate in the angle adjustment mechanism. When the central tube in the angle adjustment mechanism is driven to rotate to a specified angle, the water outlet on the central tube is aligned with the detection beam emitted by the detection sensor, and then the detection sensor sends a signal to the controller.

[0031] Furthermore, a mounting bracket is connected to the hopper, and the detection sensor is connected to the mounting bracket.

[0032] Furthermore, the lifting bracket includes a frame and at least one support block connected to the top of the frame, the support block being provided with a V-shaped groove;

[0033] The frame is connected to the lifting drive mechanism, which drives the frame to rise and thus lifts the support block to extend into the storage channel and lift the central tube stored in the hopper.

[0034] After adopting the above technical solution, the hopper stores multiple central tubes. First, the lifting drive mechanism drives the lifting bracket to rise, so that the lifting bracket extends upward into the storage channel and lifts the central tubes stored in the hopper. Then, the angle adjustment mechanism clamps the central tube lifted by the lifting bracket and drives the central tube to rotate. During this process, the detection sensor detects the angle of the rotating central tube in the angle adjustment mechanism. When the detection sensor detects that the central tube has rotated to a specified angle, it sends a signal to the controller. Then, the controller controls the angle adjustment mechanism to stop driving the central tube to rotate, and then controls the angle adjustment mechanism to release the central tube so that the central tube is back on the lifting bracket. Then, the handling robot grabs the central tube that has rotated to the specified angle on the lifting bracket and moves the central tube for loading. During the feeding process, each central tube in the hopper is rotated to a designated angle by the angle adjustment mechanism to adjust the orientation of its water outlet. This ensures that the water outlets on each central tube picked up and transported by the handling robot face the same direction. Therefore, after each central tube is loaded, the orientation of its water outlet is identical, achieving fixed-angle feeding of the central tubes. Thus, by simply adjusting the position of the ultrasonic welding gun to match the feeding angle of the central tubes, it can be ensured that the water outlet of each central tube is not aligned with the ultrasonic welding gun after loading.

[0042] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0043] like Figures 1-6 As shown, a central tube fixed-angle feeding mechanism includes a frame 1, a hopper 2, a lifting bracket 3, a lifting drive mechanism 4, an angle adjustment mechanism 5, a detection sensor 6, a controller, and a handling robot 7.

[0044] The hopper 2 is used to store the central tube 8, and the bottom of the hopper 2 is provided with a support channel 9;

[0045] The lifting bracket 3 is connected to the lifting drive mechanism 4. The lifting drive mechanism 4 is used to drive the lifting bracket 3 to rise so that the lifting bracket 3 extends upward into the storage channel 9 and lifts the central tube 8 stored in the hopper 2.

[0046] The angle adjustment mechanism 5 is connected to the frame 1 and is used to clamp the central tube 8 that is supported by the lifting bracket 3 and drive the central tube 8 to rotate.

[0047] The detection sensor 6 is connected to the controller, and the detection sensor 6 is used to send a signal to the controller when it detects that the central tube 8 driven to rotate in the angle adjustment mechanism 5 has rotated to a specified angle.

[0048] The controller is connected to the angle adjustment mechanism 5. After receiving the signal sent by the detection sensor 6, the controller controls the angle adjustment mechanism 5 to stop driving the central tube 8 to rotate and controls the angle adjustment mechanism 5 to release the central tube 8 so that the central tube 8 is supported on the lifting bracket 3.

[0049] The handling robot 7 is used to grab the central tube 8 on the lifting bracket 3 and rotate it to a specified angle, and then move the central tube 8 to load the material.

[0050] Specifically, the hopper 2 contains multiple central tubes 8. First, the lifting drive mechanism 4 drives the lifting bracket 3 to rise, so that the lifting bracket 3 extends upward into the storage channel 9 and lifts the central tubes 8 stored in the hopper 2. Then, the angle adjustment mechanism 5 clamps the central tube 8 lifted by the lifting bracket 3 and drives the central tube 8 to rotate. During this process, the detection sensor 6 detects the angle of the rotating central tube 8 in the angle adjustment mechanism 5. When the detection sensor 6 detects that the central tube 8 has rotated to a specified angle, it sends a signal to the controller. Then, the controller controls the angle adjustment mechanism 5 to stop driving the central tube 8 to rotate, and then controls the angle adjustment mechanism 5 to release the central tube 8 so that the central tube 8 is once again supported on the lifting bracket 3. Then, the handling robot 7 grabs the central tube 8 that has rotated to the specified angle on the lifting bracket 3 and moves the central tube 8 to be loaded. In this embodiment, each central tube 8 in the hopper 2 is rotated to a specified angle by the angle adjustment mechanism 5 during the feeding process to adjust the angle of the water outlet 22. This ensures that the water outlet 22 on each central tube 8 picked up and transported by the handling robot 7 faces the same direction. Therefore, the angle of the water outlet 22 is the same after each central tube 8 is transported and fed, thus achieving fixed-angle feeding of the central tube 8. Therefore, it is only necessary to adjust the position of the ultrasonic welding gun to match the feeding angle of the central tube 8 to ensure that the water outlet 22 of each central tube 8 will not face the ultrasonic welding gun after being transported and fed. In this embodiment, the lifting bracket 3 can only lift one central tube 8 at a time, the hopper 2 is connected to the frame 1, the handling robot 7 can be an articulated robot or a gantry robot, and the controller can be a PLC controller.

[0051] like Figure 1 , 2 As shown in Figures 3 and 5, the lifting drive mechanism 4 includes at least one linear module 10. The lifting bracket 3 is connected to the linear module 10. The linear module 10 is connected to the frame 1 and is used to drive the lifting bracket 3 to rise so that the lifting bracket 3 extends into the storage channel 9 during the rising process and lifts the central tube 8 stored in the hopper 2. Specifically, the linear module 10 is also used to drive the lifting bracket 3 to descend. When the lifting bracket 3 descends to the position, the upper end of the lifting bracket 3 is still located in the storage channel 9 to prevent the central tube 8 in the hopper 2 from falling out of the storage channel 9.

[0052] like Figure 1 , 2As shown in Figures 3 and 5, the lifting drive mechanism 4 includes two parallel linear modules 10. Both linear modules 10 are synchronous belt type linear modules and are connected to each other by a synchronous transmission shaft 11. One of the linear modules 10 is connected to a drive motor 12 so that the drive motor 12 drives one of the linear modules 10 to move, thereby driving the other linear module 10 to move synchronously through the synchronous transmission shaft 11, thus enabling the lifting bracket 3 to move up and down.

[0053] like Figure 1 , 2 As shown in Figures 6 and 7, the angle adjustment mechanism 5 may include a first slide block 13, a first top shaft 14, a second slide block 15, a second top shaft 16, a clamping drive mechanism, and a rotation drive mechanism.

[0054] The first slide block 13 and the second slide block 15 are slidably connected to the frame 1 along the axial direction of the central tube 8 on the lifting bracket 3. The first slide block 13 is located on one side of the central tube 8 on the lifting bracket 3, and the second slide block 15 is located on the other side of the central tube 8 on the lifting bracket 3.

[0055] The first top shaft 14 is rotatably connected to the first slide block 13, and the second top shaft 16 is rotatably connected to the second slide block 15;

[0056] The clamping drive mechanism is connected to the frame 1 and is connected to the first slide 13 and the second slide 15 respectively. The clamping drive mechanism is used to drive the first slide 13 to move toward the center tube 8 on the lifting bracket 3, thereby driving the first top shaft 14 to press against one end of the center tube 8 on the lifting bracket 3. The clamping drive mechanism is also used to drive the second slide 15 to move toward the center tube 8 on the lifting bracket 3, thereby driving the second top shaft 16 to press against the other end of the center tube 8 on the lifting bracket 3, thereby causing the first top shaft 14 and the second top shaft 16 to clamp the center tube 8 on the lifting bracket 3.

[0057] The rotary drive mechanism is connected to the first slide block 13 and connected to the first top shaft 14, and is used to drive the first top shaft 14 to rotate, thereby driving the central tube 8 clamped by the first top shaft 14 and the second top shaft 16 to rotate.

[0058] The controller is connected to the rotary drive mechanism and the clamping drive mechanism respectively. After receiving the signal sent by the detection sensor 6, the controller controls the rotary drive mechanism to stop driving the first top shaft 14 to rotate and controls the clamping drive mechanism to drive the first slide 13 and the second slide 15 to move away from the central tube 8 on the lifting bracket 3, thereby causing the first top shaft 14 and the second top shaft 16 to release the central tube 8 so that the central tube 8 can be reloaded on the lifting bracket 3.

[0059] like Figure 1 , 2 As shown in Figures 6 and 7, the rotary drive mechanism may include a rotary motor 17, a drive wheel, a driven wheel, and a transmission component;

[0060] The drive wheel is connected to the rotary motor 17;

[0061] The driven wheel is connected to the first top shaft 14;

[0062] The transmission component is connected to the driving wheel and the driven wheel;

[0063] The rotary motor 17 is connected to the first slide block 13 and is used to drive the drive wheel to rotate, which in turn drives the driven wheel and the first top shaft 14 to rotate through the transmission component, thereby driving the central tube 8 clamped by the first top shaft 14 and the second top shaft 16 to rotate. In this embodiment, both the drive wheel and the driven wheel can be synchronous pulleys, the transmission component can be a synchronous belt, and the controller is connected to the rotary motor 17 in the rotary drive mechanism. When the controller controls the rotary motor 17 to rotate, it can drive the first top shaft 14 to rotate, which in turn can drive the central tube 8 to rotate. When the controller receives the signal sent by the detection sensor 6, it will control the rotary motor 17 to stop rotating, which will cause the first top shaft 14 to stop rotating, which will cause the central tube 8 to stop rotating.

[0064] like Figure 1 , 2 As shown in Figures 6 and 7, a protective cover 18 is connected to the first slide block 13 for covering the outside of the driving wheel, the driven wheel and the transmission component.

[0065] In this embodiment, the clamping drive mechanism includes a first cylinder 19 and a second cylinder 20. The cylinder body of the first cylinder 19 is connected to the frame 1, and the piston rod of the first cylinder 19 is connected to the first slide block 13. The first cylinder 19 drives the first slide block 13 to move towards or away from the central tube 8 on the lifting bracket 3. The cylinder body of the second cylinder 20 is connected to the frame 1, and the piston rod of the second cylinder 20 is connected to the second slide block 15. The second cylinder 20 drives the second slide block 15 to move towards or away from the central tube 8 on the lifting bracket 3. The thrust of the first cylinder 19 and the thrust of the second cylinder 20 are different. Specifically, the controller is connected to the first cylinder 19 via a first electromagnetic reversing valve, and the controller is connected to the second cylinder 20 via a second electromagnetic reversing valve. When the first cylinder 19 extends, it drives the first slide block 13 to move toward the central tube 8, thereby causing the first top shaft 14 to press against one end of the central tube 8. When the second cylinder 20 extends, it drives the second slide block 15 to move toward the central tube 8, thereby causing the second top shaft 16 to press against the other end of the central tube 8. Thus, the central tube 8 can be clamped by the first top shaft 14 and the second top shaft 16. Then, the rotary motor 17 in the rotary drive mechanism drives the driving wheel to rotate, which in turn drives the driven wheel and the first top shaft 14 to rotate through the transmission component, thereby driving the central tube 8 clamped by the first top shaft 14 and the second top shaft 16 to rotate. When the controller receives the signal sent by the detection sensor 6, the controller controls the first cylinder 19 to retract through the first electromagnetic reversing valve and controls the second cylinder 20 to retract through the second electromagnetic reversing valve, thereby causing the first top shaft 14 and the second top shaft 16 to release the central tube 8 so that the central tube 8 can be re-supported on the lifting bracket 3. More specifically, the force of the first top shaft 14 pressing against the central tube 8 comes from the thrust of the first cylinder 19, and the force of the second top shaft 16 pressing against the central tube 8 comes from the thrust of the second cylinder 20. Therefore, each time the first top shaft 14 and the second top shaft 16 clamp the central tube 8, the one with the larger thrust of the first cylinder 19 and the second cylinder 20 can always extend into place, thereby ensuring that the axial position of the central tube 8 remains the same each time it is clamped by the first top shaft 14 and the second top shaft 16.

[0066] Of course, in some embodiments, the clamping drive mechanism may also have the following structure: the clamping drive mechanism may include a bidirectional lead screw, a first nut, a second nut, and a clamping motor; wherein, the first nut is connected to the first slide 13, the second nut is connected to the second slide 15, the bidirectional lead screw is rotatably connected to the frame 1, one end of the bidirectional lead screw is provided with a right-hand threaded portion that engages with the first nut, and the other end of the bidirectional lead screw is provided with a left-hand threaded portion that engages with the second nut, the clamping motor is connected to the bidirectional lead screw and is used to drive the bidirectional lead screw to rotate, thereby driving the first nut and the second nut to move towards each other, thereby causing the first slide 13 to move toward the central tube 8 and the second slide 15 to also move toward the central tube 8.

[0067] like Figure 1 , 2As shown in Figure 6, the detection sensor 6 can be a laser sensor and is used to emit a detection beam 21 to the central tube 8 that is driven to rotate in the angle adjustment mechanism 5. When the central tube 8 in the angle adjustment mechanism 5 is driven to rotate to a specified angle, the water outlet 22 on the central tube 8 is aligned with the detection beam 21 emitted by the detection sensor 6, and then the detection sensor 6 sends a signal to the controller. Specifically, after the lifting drive mechanism 4 drives the lifting bracket 3 to rise, the lifting bracket 3 will lift a central tube 8 in the hopper 2. Then, the first top shaft 14 and the second top shaft 16 can clamp the lifted central tube 8. Then, the rotation drive mechanism drives the first top shaft 14 to rotate, thereby driving the central tube 8 clamped by the first top shaft 14 and the second top shaft 16 to rotate, so as to adjust the angle of the water outlet 22 on the central tube 8. During the rotation of the central tube 8, the detection sensor 6 emits a detection beam 21 towards the central tube 8. When the central tube 8 rotates to a specified angle, the detection beam 21 emitted by the detection sensor 6 aligns with the water outlet 22 on the central tube 8, thereby triggering the detection sensor 6 to generate a signal and send the signal to the controller. After receiving the signal sent by the detection sensor 6, the controller first controls the rotation drive mechanism to stop driving the first top shaft 14 to rotate, then controls the first cylinder 19 in the clamping drive mechanism to retract to drive the first slide 13 to move away from the central tube 8 on the lifting bracket 3, and controls the second cylinder 20 in the clamping drive mechanism to retract to drive the second slide 15 to move away from the central tube 8 on the lifting bracket 3, thereby causing the first top shaft 14 and the second top shaft 16 to release the central tube 8 so that the central tube 8 is once again supported on the lifting bracket 3. Then the handling robot 7 will grab the central tube 8 that has rotated to the specified angle on the lifting bracket 3 and move the central tube 8 for loading. In this embodiment, the detection sensor 6 can specifically be a diffuse reflection laser sensor.

[0068] like Figure 1 , 2 As shown in Figures 6 and 7, a mounting bracket 23 is connected to the hopper 2, and the detection sensor 6 is connected to the mounting bracket 23.

[0069] like Figures 2-5 As shown, the lifting bracket 3 may include a frame 24 and at least one support block 25 connected to the top of the frame 24, and the support block 25 is provided with a V-shaped support groove;

[0070] The frame 24 is connected to the lifting drive mechanism 4, which drives the frame 24 to rise, thereby lifting the support block 25 to extend into the storage channel 9 and lift the central tube 8 stored in the hopper 2. In this embodiment, the angle adjustment mechanism 5 is used to clamp the central tube 8 on the support block 25 and drive the central tube 8 to rotate. After the angle adjustment mechanism 5 releases the central tube 8, the central tube 8 will be supported on the support block 25 again. The handling robot 7 is used to grab the central tube 8 rotated to a specified angle on the support block 25 and move the central tube 8 to move it for loading. The frame 24 is connected to the linear module 10. When the lifting bracket 3 is lowered into position, the support block 25 in the lifting bracket 3 is still located in the storage channel 9 to prevent the central tube 8 in the hopper 2 from falling out of the storage channel 9.

[0071] In summary, the hopper 2 contains multiple central tubes 8. First, the lifting drive mechanism 4 drives the lifting bracket 3 to rise, so that the lifting bracket 3 extends upward into the storage channel 9 and lifts the central tubes 8 stored in the hopper 2. Then, the angle adjustment mechanism 5 clamps the central tube 8 lifted by the lifting bracket 3 and drives the central tube 8 to rotate. During this process, the detection sensor 6 detects the angle of the rotating central tube 8 in the angle adjustment mechanism 5. When the detection sensor 6 detects that the central tube 8 has rotated to a specified angle, it sends a signal to the controller. Then, the controller controls the angle adjustment mechanism 5 to stop driving the central tube 8 to rotate, and then controls the angle adjustment mechanism 5 to release the central tube 8 so that the central tube 8 is once again supported on the lifting bracket 3. Then, the handling robot 7 grabs the central tube 8 that has rotated to the specified angle on the lifting bracket 3 and moves the central tube 8 to be loaded. During the feeding process, each central tube 8 in the hopper 2 is rotated to a designated angle by the angle adjustment mechanism 5 to adjust the orientation of the water outlet 22. This ensures that the water outlet 22 on each central tube 8 picked up and transported by the handling robot 7 faces the same direction. Therefore, the orientation of the water outlet 22 is the same after each central tube 8 is loaded, thus achieving fixed-angle loading of the central tube 8. Therefore, by simply adjusting the position of the ultrasonic welding gun to match the loading angle of the central tube 8, it can be ensured that the water outlet 22 of each central tube 8 will not face the ultrasonic welding gun after being loaded.
