Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a welding device and welding method for the upper rail tab of a drawer slide. Background Technology

[0002] Drawer slides are common mechanical components widely used in furniture (such as drawer cabinets, tables, etc.), automobiles, and home appliances. Their main function is to support and guide the sliding of drawers, ensuring that drawers can open and close smoothly. In the structure of drawer slides, the upper rail lever is a key component, usually used to adjust or control the gap between the drawer and the slide, and to ensure the stability of the slide during use. Welding is a key process used to fix the lever to the upper rail when manufacturing the slide. Drawer slides are divided into left and right slides, and the left and right slide structures are mirror images. Therefore, existing welding devices can only weld the left slide and lever of one drawer or the right slide and lever of one drawer at a time, which results in low welding efficiency and the need for manual positioning and fixing of the lever.

[0014] A method for welding upper rail tabs of drawer slides using a welding device, the method comprising:

[0015] S1. Adjusting the conveyor group 1 and the conveyor mechanism: Turn the crank, and with the cooperation of the transmission wheel and belt on the same side, make the two threaded rods 1 rotate simultaneously, so that the two guide plates 1 move back and forth on the upper side of the two conveyor belts 1 to the appropriate position, so that the conveyor group 1 can transport drawer slides of different lengths. Turn the transmission component 1, and drive the outer support frame on the front side to slide back and forth on the outer surface of the track 2 to the appropriate position, so that the conveyor mechanism can also be used for drawer slides of different lengths.

[0016] S2. Slide rail loading: Start motor one, and with the cooperation of the transmission wheel and belt, the four rotating shafts one rotate simultaneously, driving two conveyor belts to transport an appropriate amount of drawer slide rails to the left. The front conveyor belt transports the drawer slide rails to the receiving rack two, and the drawer slide rails on the rear conveyor belt one are transported to the receiving rack one. Two machine clamps clamp the drawer slide rails. The sliding part, together with the F-shaped plate, drives the two machine clamps one to move upward to the appropriate position. Start motor two to drive the threaded rod two to rotate, so that the sliding part and the F-shaped plate drive the two machine clamps one to move forward to the appropriate position. Then the sliding part drives the F-shaped plate to move downward to the appropriate position. Finally, the machine clamps place the drawer slide rails to the right side of the outer support frame.

[0017] S3. Slide rail welding: Hydraulic cylinder two works in conjunction with connecting frame, telescopic component, and anti-collision component to move the drawer slide rails on the right side of the inner support frame, which in turn move the receiving frame two and the outer support frame to the left side of the outer support frame. When they reach the middle position, the pushing component pushes the two drawer slide rails in the middle into the welding group for welding. After welding, they are then moved to the left side of the outer support frame by the inner support frame. In conjunction with placement component two, the welded drawer slide rails enter the unloading group for sorting and unloading.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This invention comprises a conveying group, a transfer group, a welding group, and a conveying mechanism. Through the coordinated operation of a motor, a rotating shaft, a transmission wheel, and a belt, a large number of drawer slide rails are conveyed via a single conveyor belt. With the assistance of the transfer group, the drawer slide rails on the front and rear conveyor belts are transported to the conveying mechanism, achieving automatic feeding of the left and right drawer slide rails. Through the coordinated operation of a paddle feeder, a machine clamp, a placement component, a transmission component, and a welding table, the paddles are automatically fed. Simultaneously, with the coordinated operation of a hydraulic rod, a tripod, a welding torch, and an external support frame, a pushing component moves the left and right drawer slide rails below the paddles for accurate welding. This enables welding operations on two sets of drawer slide rails and paddles without manual intervention, shortening working time, improving welding efficiency, enhancing the automation level of drawer slide rail processing, and ensuring consistent processing quality.

[0020] 2. In practical use, the present invention, through the coordinated use of conveyor belt 1, rotating shaft 1, transmission wheel, belt, and outer support frame and inner support frame, not only realizes the transportation of a large number of drawer slides, but also, with the coordinated use of crank handle, threaded rod 1, transmission wheel belt, transmission component 1, and track 2, makes the conveying group 1 and conveying mechanism suitable for drawer slides of different lengths, making the application range of the device wider.

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] Example 1, as Figure 1-2 As shown, a drawer slide rail upper rail pawl welding device includes a support leg 1, a conveying group 2 fixedly connected to the upper right side of the support leg 1, a motor 3 provided at the upper rear of the conveying group 2, a conveying mechanism 6 fixedly connected to the upper left side of the support leg 1, a transfer group 4 provided at the right rear of the conveying mechanism 6, and a welding group 5 provided in the middle of the conveying mechanism 6.

[0034] It should be noted that the specific installation method, circuit connection method, and control method of motor 3 in this invention are all conventional designs and are standard design methods used by designers.

[0035] First, place an appropriate amount of drawer slides on the front and rear sides of conveyor group 2. Then, start motor 3 to drive conveyor group 2. Conveyor group 2 transports the drawer slides to the left. The drawer slides located in front of conveyor group 2 are transported to the right side of conveyor mechanism 6, while the drawer slides located behind conveyor group 2 are transported to the bottom of transfer group 4. Transfer group 4 then transfers the drawer slides to the upper right side of motor 3. Conveyor mechanism 6 then transports them to the left. When they reach the bottom of welding group 5, welding group 5 welds the upper rail tabs to the drawer slides. They are then transported to the left side of conveyor mechanism 6 and unloaded from the far left of conveyor mechanism 6. In addition, by adjusting conveyor group 2 and conveyor mechanism 6, it can be adapted to drawer slides of different lengths, increasing the applicability of the device.

[0036] To enable the transport of drawer slides of different lengths, such as Figure 3 As shown, the conveyor assembly 2 includes a base plate 21. Mounting brackets 23 are fixedly connected to the front and rear sides of the upper end of the base plate 21, with the front mounting bracket 23 positioned slightly to the right. Rotating shafts 22 are rotatably connected to the left and right sides of the inner cavities of both mounting brackets 23. A conveyor belt 28 is wound around the outer surfaces of the two rotating shafts 22 on the same side. Brackets 25 are fixedly connected to the left and right sides of the upper end of both mounting brackets 23. Threaded rods 27 are rotatably connected to the middle of the upper end of both mounting brackets 23. The threaded rod located on the front side... A handle 24 is fixedly connected to the front end of the mounting bracket 23. The outer surfaces of the two brackets 25 and the threaded rod 27 on the same side are provided with guide plates 26. The ends of the two rotating shafts 22 and the two threaded rods 27 on the left side are fixedly connected to transmission wheels 29. The two transmission wheels 29 on the same side are connected by belts. The lower end of the base plate 21 is fixedly connected to the upper left side of the support leg 1. The rear end of the rotating shaft 22 on the left rear side is fixedly connected to the output end of the motor 3.

[0037] First, depending on the length of the drawer slide, turn the crank handle 24, which in turn rotates the threaded rod 27 fixedly connected to the crank handle 24. Through the cooperation of the transmission wheel 29 and belt fixedly connected to the crank handle 24, the transmission wheel 29 located at the rear and the threaded rod 27 rotating with the transmission wheel 29 will rotate together. This causes the two guide plates 26 to slide forward or backward simultaneously on the bracket 25 on the same side to a suitable position, making the distance between the conveyor belt 28 and the guide plate 26 suitable for drawer slides of different lengths. Then... Appropriate drawer slides are placed on the rear side of the two conveyor belts 28 and between the guide plate 26. Then, by starting the motor 3, the motor 3 drives the rotating shaft 22 located on the rear side to rotate. With the cooperation of the transmission wheel 29 and belt on the same side, the rotating shaft 22 on the front side is driven to rotate together. This drives the two conveyor belts 28 to rotate to the left at the same time, so that the drawer slides on the front and rear sides are transported to the left. Finally, the purpose of transporting drawer slides of different lengths is achieved. The two conveyor belts 28 are used to distinguish between left and right slides.

[0038] In order to transfer the drawer slide rail located on the rear conveyor belt 28 to the right side of the conveyor mechanism 6 in real time, such as Figure 4 and Figure 5 As shown, the transfer group 4 includes an F-shaped bracket 41 and two receiving frames 47. A track 48 is fixedly connected to the upper right side of the F-shaped bracket 41. A threaded rod 42 is rotatably connected to the upper left side of the F-shaped bracket 41. A motor 45 is fixedly connected to the rear end of the threaded rod 42. The right end of the motor 45 is fixedly connected to the rear left side of the F-shaped bracket 41. A sliding component 44 is provided on the outer surface of the threaded rod 42 and the outer surface of the track 48. An F-shaped plate 43 is provided on the right side of the sliding component 44. Two machine clamps 46 are fixedly connected to the lower right side of the F-shaped plate 43. The upper right side of the outer surface of the two receiving frames 47 is in contact with the left side of the outer surface of the conveyor belt 28 located at the rear.

[0039] It should be noted that the specific installation method, circuit connection method, and control method of the motor 45 and the machine clamp 46 in this invention are all conventional designs and are the usual design methods of designers. In addition, the sliding component 44 is composed of a sliding sleeve and a cylinder. The cylinder is used in conjunction with an external air pump and air pipe, which is not shown in this invention. The right side of the sliding sleeve can be slidably connected to the outer surface of the track 48, and the left side of the sliding sleeve can be engaged with the outer surface of the threaded rod 42. Through the operation of the cylinder, the F-shaped plate 43, which is fixedly connected to the output end of the cylinder, moves vertically up and down.

[0040] First, the drawer slides on the rear conveyor belt 28 are transported from the left side of the conveyor belt 28 to the upper end of the two receiving racks 47. Then, through the sliding component 44 and the F-shaped plate 43, the two clamping jaws 46 move vertically downwards and clamp the drawer slides on the receiving racks 47. Next, through the sliding component 44 and the F-shaped plate 43, the two clamping jaws 46 move the drawer slides upwards. Then, by starting the motor 45, the motor 45 drives the threaded rod 42 to rotate, thereby causing the drawer slides to move upwards. Component 44 moves forward to a suitable position on the outer surface of threaded rod 42 and track 48. Then, the sliding component 44, in conjunction with F-shaped plate 43 and machine clamp 46, places the drawer slide rail on the right side of the conveying mechanism 6. After placement, the sliding component 44, in conjunction with F-shaped plate 43, drives the two machine clamps 46 to move upward, and the motor 45 drives threaded rod 42 to rotate in the opposite direction, causing the sliding component 44 to slide backward and return to its initial state. Finally, the purpose of transferring the drawer slide rail located on the rear conveyor belt 28 to the right side of the conveying mechanism 6 is achieved.

[0041] Example 2: Based on Example 1, this example involves transporting drawer slides of different lengths to the left to achieve the purpose of unloading materials, such as... Figure 6 and 7 As shown, the conveying mechanism 6 includes two outer supports 64. A base plate 61 is fixedly connected to the lower end of the rear outer support 64. Tracks 67 are slidably connected to the left and right sides of the lower end of the front outer support 64. The lower ends of the two tracks 67 are fixedly connected to the upper end of the base plate 61. A transmission component 68 is provided in the middle of the front outer support 64 and the middle of the upper end of the base plate 61. A feeding assembly 66 is fixedly connected to the left side of the upper end of the base plate 61. Four mounting slots 690 are provided in the middle of the upper end of the base plate 61. Connecting plates 691 are slidably connected to the inner cavities of two mounting slots 690 on the same side. An inner support 63 is fixedly connected to the upper end of the two connecting plates 691. Placement components 65 are fixedly connected to the left side of the two outer supports 64 at their opposite ends. The lower ends of the two connecting plates 691 are fixedly connected to the inner supports 63. A connecting frame 693 is fixedly connected to the base plate 61. A telescopic component 694 is slidably connected to the upper side of the outer surface of the connecting frame 693. A symmetrical anti-collision component 692 is fixedly connected to the lower front side of the lower middle part of the base plate 61. A hydraulic cylinder 695 is fixedly connected to the lower side of the middle part of the outer surface of the left anti-collision component 692. The output end of the hydraulic cylinder 695 is fixedly connected to the left side of the telescopic component 694. A receiving frame 62 is fixedly connected to the right end of each of the two outer support frames 64. The lower end of the base plate 61 is fixedly connected to the upper left side of the support leg frame 1. The lower end of the F-shaped bracket 41 is fixedly connected to the upper right rear part of the base plate 61. The lower ends of the two receiving frames 47 are fixedly connected to the upper right rear part of the base plate 61. The lower right side of the outer surface of the two receiving frames 62 is in contact with the left side of the outer surface of the front conveyor belt 28.

[0042] It should be noted that the specific installation method, circuit connection method, and control method of the hydraulic cylinder 695 in this invention are all conventional designs and are standard design methods used by designers. The placement component 695 consists of a U-shaped locking pin, a fixing plate, and a cylinder. The output end of the cylinder is connected to the U-shaped locking pin, and the lower end of the cylinder is connected to the fixing plate. The fixing plate is fixedly connected to the outer support frame 64. In addition, the telescopic component 694 consists of a sliding plate and a hydraulic cylinder. The sliding plate is slidably connected to the lower end of the base plate 61. The output end of the hydraulic cylinder is fixedly connected to the connecting frame 693. The output end of the hydraulic cylinder 695 is fixedly connected to the left end of the sliding plate. The transmission component 68 consists of a screw, a rotating seat, and a rotating handle. A threaded sleeve that matches the screw in the transmission component 68 is fixedly connected to the lower middle part of the outer support frame 64 located on the front side. The pushing component 69 consists of the hydraulic cylinder 695, a fixing plate, and two support plates. The two support plates can push the two drawer slide rails to slide towards the lower part of the welding group 5. The fixing plate is fixedly connected to the outer support frame 64 located on the front side.

[0043] Two grooves adapted to the drawer slides are provided on the left side of the two opposing outer support brackets 64. A placement component 65 is fixed to one of the opposite ends on the same side. A U-shaped locking pin in the placement component 65 passes through the groove, preventing the drawer slide from sliding downwards within the groove. First, according to the different lengths of the drawer slides, adjust the transmission component 68 so that it drives the outer support bracket 64 located on the front side to move forward or backward on the outer surface of the track 67 to a suitable position, making it suitable for drawer slides of different lengths. When located on the front conveyor belt... The drawer slides on conveyor belt 128 are transported to receiving rack 22. When the drawer slides on conveyor belt 128 are transported to the right side of outer support frame 64 via transfer group 4, the telescopic component 694 drives the connecting frame 693 to work with the connecting plate 691 to move the inner support frame 63 upward. This causes the inner support frame 63 to drag the drawer slides upward. Simultaneously, the hydraulic cylinder 2695 drives the telescopic component 694 to slide to the left. With the combined action of the connecting frame 693, connecting plate 691, and inner support frame 63, the drawer slides move to the left. Then, the telescopic component... 694 drives the connecting bracket 693 and connecting plate 691 to move downwards, which in turn causes the inner support bracket 63 to move the drawer slide downwards, so that the drawer slide is placed back on the outer support bracket 64. Then, the hydraulic cylinder 695 pushes the telescopic component 694 to move to the left to return to its initial position. The anti-collision components 692 installed on the left and right sides play a buffering and anti-collision role. This cycle of operation allows the drawer slide to move to the left on the outer support bracket 64. When it moves to the pushing component 69, the pushing component 69 pushes the two drawer slides to slide backwards until they are welded. At the lower part of the connecting group 5, the upper rail lever is welded to the upper side of the drawer slide rail by the welding group 5. After the welding is completed, the two welded drawer slide rails are pulled forward to return to their initial state by the pushing component 69. Then, they are moved to the left by the inner support frame 63 to the leftmost side of the outer support frame 64. By controlling the placement component 65, the two welded drawer slide rails on the left slide into the unloading group 66. The unloading group 66 drives the drawer slide rails forward to complete the unloading. Finally, the purpose of unloading drawer slide rails of different lengths is achieved by transporting them to the left side.

[0044] To further explain, such as Figure 8 As shown, the unloading assembly 66 includes a mounting frame 662. Rotating shafts 661 are rotatably connected to both the front and rear sides of the inner cavity of the mounting frame 662. A conveyor belt 663 is wound around the outer surfaces of the two rotating shafts 661. Supports 665 are fixedly connected to both the front and rear sides of the upper end of the mounting frame 662. A guide plate 666 is slidably connected to the middle of the outer surfaces of the two supports 665. A motor 664 is fixedly connected to the right end of the rear rotating shaft 661. The left end of the motor 664 is fixedly connected to the rear right end of the mounting frame 662. The lower end of the mounting frame 662 is fixedly connected to the left side of the upper end of the base plate 61.

[0045] In detail, it should be noted that the specific installation method, circuit connection method, and control method of the motor 364 in this invention are all conventional designs and are standard design methods used by designers.

[0046] In detail, when the two welded drawer slides fall behind the second conveyor belt 663, the two drawer slides are separated on the left and right sides of the guide plate 666. Then, the third motor 664 is started to drive the rotating shaft 661 to rotate, so that the second conveyor belt 663 carries the drawer slides forward and drops them from the front side, thus achieving the purpose of unloading.

[0047] To achieve the purpose of welding the drawer slides together, such as... Figure 9 As shown, welding assembly 5 includes a base plate 2 51. A tripod 56 is fixedly connected to the upper end of the base plate 2 51. A hydraulic rod 3 57 is fixedly connected to the middle of the upper end of the tripod 56. The output end of the hydraulic rod 3 57 passes through the tripod 56 and is fixedly connected to symmetrical welding torches 591. Auxiliary rods 58 are fixedly connected to the rear side of the upper end of each of the two welding torches 591. Circular holes 59 are opened on the rear side of the left and right sides of the upper end of the tripod 56. The inner cavities of the two circular holes 59 are slidably connected to the outer surfaces of the two auxiliary rods 58, respectively. The upper end of the base plate 2 51 is fixedly connected to the left... The two transmission components 52 are symmetrically arranged on the right. Each of the two transmission components 52 is equipped with a machine clamp 53 on one side close to each other. Each of the two transmission components 52 is fixedly connected to a placement component 54 on the lower side close to each other. The upper middle part of the base plate 51 is equipped with a welding platform 55 symmetrically arranged on the left and right. The left and right sides of the rear end of the base plate 51 are fixedly connected with a paddle feeder 590. The lower end of the base plate 51 is fixedly connected to the upper middle part of the base plate 61. The lower ends of the two paddle feeders 590 are fixedly connected to the rear side of the upper middle part of the base plate 61.

[0048] It should be noted that the specific installation methods, circuit connections, and control methods of the hydraulic rod 57, the paddle feeder 590, the machine clamp 53, and the welding torch 591 in this invention are all conventional designs and are standard design methods used by designers. The paddle feeder 590 can automatically feed the upper rail paddles, transporting them to the placement component 54. The transmission component 52 consists of an L-shaped plate, a vertically arranged cylinder, a horizontally arranged short hydraulic rod, a cross plate, and a sliding block. The output end of the cylinder is fixedly connected to the upper end of the short hydraulic rod, and the output end of the short hydraulic rod is fixedly connected to the upper end of the cross plate. The outer surface of the cross plate is slidably connected to the front side of the sliding block, and the rear side of the sliding block is slidably connected to the L-shaped plate in the transmission component 52. The lower end of the short hydraulic rod is fixedly connected to the sliding block. The front end of the cross plate near the welding torch 591 is fixedly connected to the machine clamp 53. These components work together to adjust the machine clamp 53 in both the horizontal and vertical directions.

[0049] When the two drawer slides are pushed to the middle of the two welding tables 55 by the pusher component 69, the upper slide plates are transported to the placement component 54 by the two paddle feeders 590. The symmetrical transmission components 52 control the clamping machine 53 on the same side, causing it to clamp the upper slide plates on the placement component 54 and transport them to the welding table 55, positioning them at a suitable position on the upper side of the drawer slides. Then, the two transmission components 52 move the clamping machine 53 away from each other, returning to its initial state. The hydraulic rod 57 drives the two welding torches 591 to move vertically downwards, and the welding torches 591 weld the drawer slides and the upper rail levers. During this process, the auxiliary rod 58 slides in the inner cavity of the round hole 59 to increase the stability of the welding torches 591. After the welding is completed, the hydraulic rod 57 drives the two welding torches 591 to move upwards to return to the initial state. At the same time, the pushing component 69 pulls the two welded drawer slides forward and separates them from the inner cavity of the welding table 55, thus completing the welding of the two drawer slides in one go.
