Description

Technical Field

[0001] This invention relates to the field of robotic arm application technology, specifically to an integrated LED strip welding equipment that uses a robotic arm to feed wires. Background Technology

[0002] LED light strips are made by assembling LEDs onto a strip-shaped FPC (flexible printed circuit board) or PCB (rigid PCB), named for their strip-like shape. Due to their long lifespan (typically 80,000-100,000 hours), energy efficiency, and environmental friendliness, they are increasingly popular in various decorative industries. The production process involves joining short and wide LED strips together using a welding device.

[0003] For example, patent document CN119216844B discloses an LED strip welding device, which includes a housing, a placement plate, and a telescopic component. The placement plate is mounted on the telescopic component, which is located on the inner bottom wall of the housing. A mounting ring is provided above the placement plate. The mounting ring can rotate around itself. Several sliding holes are opened on the inner side of the mounting ring. A movable cylinder is slidably connected inside the sliding holes, and a piston is installed on the movable cylinder. In the LED strip welding device of the present invention, when the ends of two LED strips are both below the welding head, the welding head welds the two LED strips.

[0004] Taking the aforementioned welding equipment as an example, during the welding process, workers need to stack the LED strips from bottom to top on the placement plate. This requires workers to operate in a confined space, which is inconvenient. Furthermore, to ensure the safety of workers, the machine needs to be stopped for LED strip stacking, resulting in slow processing speed of the welding equipment. Summary of the Invention

[0036] A welding device consists of a storage mechanism 1, a welding mechanism 2, a feeding mechanism 3, a loading mechanism 4, a gripping robot 5, and two grippers 6. In this application, the directions left and right, front and back, and up and down are described using... Figure 2 For the purposes shown, and since both welding mechanism 2 and feeding mechanism 3 are publicly available technologies, they will not be described in detail here. For more information, please refer to the LED strip welding device disclosed in the patent document with announcement number CN119216844B.

[0037] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 In the storage mechanism 1, the storage box 11 is installed on the ground. Multiple pads 15 are provided on both sides of the storage box 11. A connecting plate 16 is fixedly connected between the multiple pads 15 on the same side. The multiple pads 15 on the same side move synchronously. The connecting plate 16 is set inside the storage box 11. Two guide plates 17 are fixedly connected inside the storage box 11. A reciprocating screw 19 is rotatably connected inside the storage box 11. The reciprocating screw 19 and the two guide plates 17 all pass through the connecting plate 16. The connecting plate 16, which is limited by the two guide plates 17, can only move left and right inside the storage box 11.

[0038] The reciprocating screw 19 is connected to the connecting plate 16 via a nut pair. The two connecting plates 16 are threaded to the threaded structures in two directions on the outside of the reciprocating screw 19, respectively. The output end of the forward and reverse motor 110 fixedly installed on the outside of the storage box 11 is fixedly connected to the reciprocating screw 19. When the forward and reverse motor 110 is controlled to rotate forward, the reciprocating screw 19 rotates clockwise, driving the two connecting plates 16 to move closer to each other, and the multiple pads 15 on the left and right sides to move closer to each other. When the forward and reverse motor 110 is controlled to rotate in reverse, the reciprocating screw 19 rotates counterclockwise, driving the two connecting plates 16 to move closer to each other. Multiple slots 14 are opened on both sides of the placement plate 13. Each slot 14 corresponds to a pad 15. The position of the pad 15 inside the slot 14 is controlled so that the multiple pads 15 support and limit the light strips of different lengths from both sides.

[0039] An electromagnet 18 is fixedly inserted on the connecting plate 16. The electromagnet 18 is in contact with the adjacent guide plate 17. After the electromagnet 18 is controlled to work, the electromagnet 18 is attracted and fixed to the immovable iron guide plate 17 by magnetic force. The connecting plate 16 is limited, ensuring the stable and efficient cooperation between the pad 15 and the placement plate 13.

[0040] The placement plate 13 is located inside the storage box 11. A pneumatic cylinder 111 and two telescopic rods 112 are fixedly connected to the bottom of the inner cavity of the storage box 11. The piston ends of the pneumatic cylinder 111 and the telescopic rods 112 are fixedly connected to the placement plate 13. Controlling the operation of the pneumatic cylinder 111 can control the placement plate 13 to move up and down inside the storage box 11.

[0041] The storage box 11 has a feed inlet 12 on the front side, which provides a channel for the gripping robot 5 to feed material to the top of the placement plate 13.

[0042] Specifically, such as Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 Infrared sensor 42 is fixedly installed on the right side of mounting box 41. Rubber block 43 is set inside mounting box 41. Infrared sensor 42 is used to detect the position of the light strip entering the top of rubber block 43. Rubber block 43 can deform. Metal frame 423 is fixedly connected to the left side inside mounting box 41. 223 provides support for cutting light strip. Support frame 44 is fixedly connected to the left side of mounting box 41 to provide support for cutting light strip.

[0043] In the support assembly, a pneumatic cylinder 412 and two telescopic rods 413 are fixedly mounted on the mounting bracket 3 411. Mounting brackets 410 are fixedly connected to both sides of the mounting bracket 3 411. In the left support assembly, the two mounting brackets 410 are fixedly connected to the support bracket 44. The left mounting bracket 3 411 cannot move. A slot 421 is opened at the bottom of the left mounting bracket 3 411. An L-shaped plate 422 is fixedly connected between the piston end of the left pneumatic cylinder 412 and the telescopic rod 413. The L-shaped plate 422 can move up and down under the action of the pneumatic cylinder 412 and the telescopic rod 413.

[0044] Vacuum pump 63 is fixedly connected to the outlet end of suction nozzle 61 in gripper 6. Solenoid valve 64 is fixedly connected to the outlet end of vacuum pump 63 to control vacuum pump 63 to work. Vacuum pump 63 draws air from inside suction nozzle 61. Rubber pad 62 is fixedly connected to the outside of suction nozzle 61. After rubber pad 62 is pressed onto the light strip, the rubber pad 62 deforms to seal between suction nozzle 61 and light strip. At this time, vacuum pump 63 is controlled to work, and suction nozzle 61 adsorbs light strip through negative pressure. After a period of time, solenoid valve 64 is controlled to work and close, vacuum pump 63 stops working, and gripper 6 clamps and fixes light strip.

[0045] In the right support assembly, the piston ends of the pneumatic cylinder 412 and the telescopic rod 413 are both fixedly connected to the suction nozzle 61 on the right side. The right support assembly can control the up and down movement of the right gripper 6. The top of the mounting bracket 411 in the right support assembly has a slot 414, which provides a channel for the up and down movement of the vacuum pump 63.

[0046] In the positioning assembly, two mounting brackets 45 are fixedly connected to the two sides inside the mounting box 41. The distance between the two mounting brackets 45 is set according to the width of the light strip, so that the front and rear of the light strip are supported and limited. When the light strip bends, the front and rear position of the light strip is restricted. One of the mounting brackets 45 is fixedly connected to the output end of the positive and negative motor 48, which is fixedly connected to the lead screw 47. The lead screw 47 is rotatably installed inside the mounting bracket 45 and can rotate. The other mounting bracket 45 is fixedly connected to the guide rod 46. The guide rod 46 and the lead screw 47 are both fitted with support brackets 49. The lead screw 47 is connected to the outer support brackets 49 through a nut pair. The rotation of the lead screw 47 can drive the support brackets 49 to move left and right. The two support brackets 49 are fixedly connected to the two mounting brackets 410 in the right support assembly. Under the support of the two support brackets 49, the two mounting brackets 410, and the mounting brackets 411, the right support assembly and the gripper 6 fixed to the right support assembly can move left and right to adjust the position of the right gripper 6.

[0047] In the auxiliary components, the piston ends of pneumatic cylinder 3 415 and telescopic rod 420 are fixedly connected to mounting bracket 416. Pneumatic cylinder 3 415 and telescopic rod 420 are respectively fixedly connected to the top of two mounting brackets 1 45. Pneumatic cylinder 3 415 and telescopic rod 420 work stably. Mounting bracket 5 417 is fixedly connected between the two mounting brackets 416. Under the action of pneumatic cylinder 3 415 and telescopic rod 420, mounting bracket 5 417 can move left and right. Pneumatic cylinder 418 and telescopic rod 3 419 fixedly inserted on mounting bracket 5 417 are fixedly connected to the left gripper 6. Under the action of pneumatic cylinder 418 and telescopic rod 3 419, the left gripper 6 can move up and down and can move left and right synchronously with mounting bracket 5 417.

[0048] A convex groove 431 is provided on the top of the metal frame 423. A reversible motor 430 is fixedly connected to the metal frame 423 inside the convex groove 431. One end of a lead screw 429 fixedly connected to the output end of the reversible motor 430 is rotatably connected to the metal frame 423. A blade 427 is fixedly connected to the top of a support frame 428 threaded on the outside of the lead screw 429. The support frame 428 cannot rotate within the convex groove 431, thus controlling the operation of the reversible motor 430. The support frame 428 and the blade 427 move back and forth. The two mounting frames 45 are each provided with a slot 424 on the side that is close to each other. The top of the blade 427 passes through a slot 424. The blade 427 is partially set on the top of the metal frame 423 and does not affect the movement of the light strip between the two mounting frames 45. The cutting assembly, which is composed of forward and reverse motor 430, lead screw 429, support frame 428, blade 427 and other structures, can move to cut the light strip supported by the metal frame 423.

[0049] Specifically, such as Figure 2 , Figure 12 , Figure 13 and Figure 14 The robotic arm and support frame 51 are fixedly connected to the front of the mounting box 41. The piston end of the pneumatic cylinder 53, which is fixedly connected to the top of the support frame 51, is fixedly connected to the track 54. The piston ends of the multiple telescopic rods 52, which are fixedly connected to the top of the support frame 51, are all fixedly connected to the track 54. With the pneumatic cylinder 53 and the multiple telescopic rods 52 moving left and right, the track 54 moves up and down stably.

[0050] A support frame 56 is fixedly connected to a railcar 55 mounted on rail 54. A pneumatic cylinder 57 and two telescopic rods 58 are fixedly mounted on the support frame 56. The piston ends of the pneumatic cylinder 57 and the telescopic rods 58 are fixedly connected to the support frame 59. A pneumatic cylinder 512 and two telescopic rods 511 are fixedly connected to the bottom of the support frame 510 fixedly connected to the support frame 59. The support frame 510 moves back and forth under the action of the pneumatic cylinder 57 and the telescopic rods 58.

[0051] The fixed assembly includes a hollow box 513 fixedly connected between the piston end of the pneumatic cylinder 512 and the piston end of the telescopic rod 511. The hollow box 513 can move up and down under the action of the pneumatic cylinder 512 and the telescopic rod 511. A pressure sensor fixedly connected inside the hollow box 513 detects the surrounding air pressure. Multiple air holes 514 are opened on the bottom of the outer side of the hollow box 513. Vacuum pumps 515 are fixedly connected to both sides of the top of the hollow box 513. An air guide pipe is fixedly connected between the air inlet of the vacuum pump 515 and the hollow box 513. 516. When the hollow box 513 is pressed to the outside of the light strip so that the multiple air holes 514 are covered by the light strip, the vacuum pump 515 is controlled to work and draw air from the inside of the hollow box 513 through the air guide pipe 516. The hollow box 513 adsorbs and fixes the light strip. The outlet end of the vacuum pump 515 is fixedly connected to the solenoid valve 517. When the solenoid valve 517 is closed, the vacuum pump 515 stops working, the inside of the hollow box 513 maintains negative pressure, and the hollow box 513 maintains the state of fixing the light strip. The fixing component can adsorb and fix the light strip.

[0052] The working principle of the welding equipment is as follows:

[0053] First, the auxiliary control component moves the left gripper 6 upward, the left support component moves the L-shaped plate 422 upward, and the right support component moves the right gripper 6 upward, thus completing the preparation work for feeding the light strip.

[0054] The staff then pulls one end of the light strip between the two mounting brackets 45, laying it flat on the metal frame 423 and the support bracket 44, aligning it with the right end of the metal frame 423. The left support component is then activated, causing the L-shaped plate 422 to move downwards onto the light strip. At this point, the L-shaped plate 422 exerts minimal pressure on the light strip, effectively smoothing it out. The right support component is then activated, driving the right gripper 6 to move downwards and press down on the light strip. After the right gripper 6 has secured one end of the light strip, the control... After the positioning component moves the right gripper 6 a certain distance to the right, it stops working. Then, the auxiliary component is controlled to move the left gripper 6 downward to press the light strip. The left gripper 6 limits the movement of the light strip, and the light strip is limited between the two grippers 6. Then, the cutting component is controlled to work. The blade 427 in the cutting component is pressed against the suction nozzle 61 in the left gripper 6. The cutting component is controlled to move the blade 427 back and forth once, and the blade 427 cuts the light strip, completing the light strip cutting work and completing the automatic cutting of the preset length of light strip.

[0055] After the light strip cutting is completed, the left support component is controlled to move the L-shaped plate 422 down and press the light strip. The light strip is limited at one end inside the mounting box 41. Then, the auxiliary component is controlled to move the left gripper 6 up and then to the right a certain distance. After that, the auxiliary component is controlled to move the left gripper 6 down to fit the cut light strip. Then, the positioning component is controlled to drive the right gripper 6 to pull the cut light strip to the right. At this time, the left gripper 6 plays a role in smoothing the cut light strip. During the process of the two grippers 6 working together to transport the cut light strip to the preset position, the warping and bending that may occur due to stress changes during the light strip cutting process are smoothed out, ensuring the quality of the cut light strip in subsequent processing. After the right gripper 6 moves a certain distance, the transport of the cut light strip is completed.

[0056] Subsequently, the auxiliary component drives the left gripper 6 to move to the top of the L-shaped plate 422. At this time, the left gripper 6 and the L-shaped plate 422 are folded together. After the right gripper 6 moves a certain distance, the gripper 6 stops working and releases the cut light strip. The right support component works to move the right gripper 6 upward. The gripper 6 leaves the detection path of the infrared sensor 42. After the infrared sensor 42 locates the right end of the cut light strip, the robotic arm controls the fixing component to move left and right according to the positioning result of the infrared sensor 42, so that the middle part of the hollow box 513 in the fixing component is aligned with the middle part of the cut light strip. Then the robotic arm controls the hollow box 513 to move downward, so that the hollow box 513 moves downward and presses the cut light strip. Since the front and rear sides of the light strip are supported, the rubber block 43 can deform after being subjected to a certain force. Therefore, as the hollow box 513 moves downward, the cut light strip bends and fits against the bottom of the hollow box 513. Then the fixing component works to adsorb and fix the light strip, completing the clamping work of the cut light strip.

[0057] After the fixing component adsorbs and fixes the light strip, the robotic arm drives the hollow box 513 to enter the storage box 11 through the feed port 12. The curvature of the cut light strip is the same as the curvature of the concave part of the placement plate 13. When the hollow box 513 moves to the top of the placement plate 13, the pneumatic cylinder 111 is controlled to work so that the placement plate 13 abuts against the cut light strip. Then the fixing component stops working, and the loading of the cut light strip is completed.

[0058] During the loading of the cut LED strip, the auxiliary component controls the left gripper 6 to move to the top of the L-shaped plate 422, causing the L-shaped plate 422 and the left gripper 6 to fold together, making room for the right gripper 6 to adsorb and fix the free end of the LED strip inside the mounting box 41. Then, the positioning component and the right support component work to press the right gripper 6 onto the free end of the LED strip. After the right gripper 6 adsorbs and fixes the LED strip, the left support component works to move the L-shaped plate 422 upward. The auxiliary component works to move the left gripper 6 and the L-shaped plate 422 upward synchronously, so that the LED strip is no longer limited by the L-shaped plate 422. After the positioning component drives the right gripper 6 to move to the right a certain distance, the auxiliary component works to move the left gripper 6 to the right and then downward to press the LED strip. The left gripper 6 limits the movement of the LED strip, completing the automatic positioning of the LED strip. Then, the above steps are followed in sequence to automatically cut the LED strip of the preset length, transport the cut LED strip, clamp the cut LED strip, and load the LED strip.

[0059] In summary, by cooperating with the feeding mechanism 4 and the gripping robot 5, the automatic circulation of light strips, automatic positioning, automatic cutting of light strips of preset length, conveying of cut light strips, clamping of cut light strips, and feeding can complete the stacking of light strips into the storage mechanism 1. This eliminates the need for personnel to stack light strips inside the confined storage mechanism 1, ensuring the speed of light strip feeding. Furthermore, the light strip feeding and stacking can be completed without stopping the welding equipment, thereby increasing the production capacity of the welding equipment.
