Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and in particular to a dual-sided collaborative support type intelligent suspension conveying system for arc welding workpieces. Background Technology

[0002] In the automotive production process, many automotive parts require arc welding. Arc welding typically involves multiple steps, and the transfer between welding steps or workstations often requires manual labor or other forms of transport. Currently, robotic transfer is often difficult to implement for some complex workpieces (such as the CCB instrument panel beam), necessitating manual transfer using external transfer racks. However, the separation between processes or equipment, the time consumed by external transfer racks, and the occasional risk of rack stacking and collisions are all issues. Therefore, existing technologies often employ overhead conveyor chains to transport workpieces.

[0003] Existing overhead conveyor systems suspend and transport workpieces via hooks. The workpieces are suspended longitudinally by hanging from hooks near the workstation through a suspension hole at one end. The conveying stops after reaching the designated position, and the workpieces are then manually removed from the hooks. However, using suspension holes to suspend the workpieces from the hooks requires operators to simultaneously adjust the position of both the workpiece and the hook to ensure the hook is precisely aligned with the suspension hole and inserted. This process is cumbersome, and retrieving the workpiece requires positional adjustments to ensure smooth removal, making the operation inconvenient. Summary of the Invention

[0004] In view of this, the purpose of this invention is to propose a dual-sided collaborative support type intelligent suspension conveying system for arc welding workpieces to solve the problem of inconvenient loading, unloading and retrieval operations when using hooks for suspension.

[0005] To achieve the above objectives, the present invention provides a dual-sided collaborative support type intelligent suspension conveying system for arc welding workpieces, including a frame and a guide rail installed on the lower side of the frame. Multiple sets of carriages are slidably arranged on the guide rail. A drive assembly is provided on the frame and the guide rail, which drives the carriages to move along the guide rail. A suspension mechanism is installed at the lower end of the carriage. The suspension mechanism includes a connector installed at the lower end of the carriage, a mounting block connected to the lower end of the connector, and a hanger provided at the lower end of the mounting block.

[0006] A further improvement is that a sliding groove is provided at the lower end of the mounting block, and a bidirectional threaded rod is rotatably installed in the sliding groove. Both ends of the bidirectional threaded rod are threaded with sliding blocks, which are slidably disposed in the sliding groove. Two sets of hangers are provided, and the two sets of hangers are connected to the corresponding sliding blocks.

[0007] A further improvement is that a limit bracket is rotatably connected to one side of the mounting block via a rotating shaft, and a torsion spring is sleeved on the rotating shaft.

[0008] A further improvement is that the surfaces of the hanger and the limiting bracket are covered with protective pads.

[0009] A further improvement is that a mounting bracket is provided on the side of the frame corresponding to the feeding and unloading points of the guide rail, and a sensor is installed on the mounting bracket.

[0010] A further improvement is that the connector includes a connecting sleeve fixedly connected to the lower end of the carriage, a connecting rod slidably installed inside the connecting sleeve, and the lower end of the connecting rod extending out from the connecting sleeve and connecting to the mounting block.

[0011] A further improvement is that the connecting sleeve has vertically equidistant locking holes on its side, and the connecting rod has fixing holes, with the locking holes and fixing holes locked together by fasteners.

[0012] The beneficial effects of this invention are as follows: By setting two sets of hangers for workpiece engagement, the workpiece is engaged between the hangers, and the hangers support the workpiece from below, allowing the workpiece to be placed stably. This replaces the hook suspension method, reduces the process of inserting the hook into the suspension hole, and greatly improves the convenience of suspension. A limiting bracket is set, which flips downward through the action of a torsion spring. The limiting bracket clamps the workpiece from the side and attaches it to the side of the mounting block, ensuring stability during movement. Attached Figure Description

[0018] like Figure 1-4 As shown, this embodiment provides a dual-sided collaborative support type intelligent suspended conveyor system for arc welding workpieces, including a frame 1 and a guide rail 2 installed on the lower side of the frame 1. The guide rail 2 has an O-shaped structure and is installed inside two workstations, between two adjacent workstations, suspended above the workstations, with the bottom space used for workpiece flow. Multiple sets of carriages 3 are slidably arranged on the guide rail 2, with a certain distance maintained between the carriages 3 to allow the two workpieces to avoid each other. A drive assembly 4 is provided on the frame 1 and the guide rail 2, which drives the carriages 3 to move along the guide rail 2. The drive assembly 4 includes a motor installed on the frame 1 and a traction chain installed on the guide rail 2. The drive assembly 4, the guide rail 2, and the carriages 3 form a suspended chain conveyor structure, which is existing technology and is not particularly limited here.

[0019] A suspension mechanism is installed at the lower end of the slide 3. The suspension mechanism includes a connector 5 installed at the lower end of the slide 3. A mounting block 6 is connected to the lower end of the connector 5. A hanger 7 is provided at the lower end of the mounting block 6. There are two sets of hangers 7. The workpiece is engaged between the two sets of hangers 7.

[0020] The connector 5 includes a connecting sleeve 16 fixedly connected to the lower end of the slide 3. A connecting rod 17 is slidably installed inside the connecting sleeve 16. The lower end of the connecting rod 17 extends out from the connecting sleeve 16 and connects to the mounting block 6. Locking holes 18 are vertically and equidistantly opened on the side of the connecting sleeve 16. Fixing holes 19 are opened on the connecting rod 17. The connecting rod 17 slides up and down inside the connecting sleeve 16 so that the fixing holes 19 correspond to the locking holes 18. The fastener 20 passes through the fixing holes 19 and the locking holes 18. The locking holes 18 and the fixing holes 19 are locked together by the fastener 20. The fastener 20 is a bolt or a pin, which can be selected according to the usage requirements.

[0021] The lower end of the mounting block 6 has a sliding groove 8, and a bidirectional threaded rod 9 is rotatably installed in the sliding groove 8. Both ends of the bidirectional threaded rod 9 are rotatably installed in the sliding groove 8 through bearing seats. One end of the bidirectional threaded rod 9 extends outward through the sliding groove 8 and is connected to a rotating handle. The bidirectional threaded rod 9 is driven to rotate by rotating the rotating handle. Both ends of the bidirectional threaded rod 9 are threadedly connected to sliding blocks 10, which are slidably set in the sliding groove 8. Two sets of hangers 7 are connected to the corresponding sliding blocks 10. By rotating the bidirectional threaded rod 9, the sliding blocks 10 are driven to slide in the sliding groove 8, and the distance between the two sets of hangers 7 is adjusted so that the workpiece is stably locked between the hangers 7.

[0022] One side of the mounting block 6 is rotatably connected to a limiting bracket 12 via a rotating shaft 11. The limiting bracket 12 is a T-shaped structure composed of a vertical bracket and a horizontal bracket, with the vertical bracket being an arc-shaped structure. A torsion spring 13 is sleeved on the rotating shaft 11, with both ends of the torsion spring 13 abutting against the mounting block 6 and the limiting bracket 12. The torsion spring 13 drives the limiting bracket 12 to rotate downward along the rotating shaft 11. The limiting bracket 12 clamps the workpiece that is engaged on the hanger 7, so that the workpiece is clamped between the limiting bracket 12 and the mounting block 6.

[0023] Both the hanger 7 and the limit bracket 12 are covered with protective pads made of materials such as rubber. The protective pads protect the hanger 7 and the limit bracket 12 from contact with the workpiece and reduce friction damage.

[0024] A mounting bracket 14 is provided on the side of the frame 1 corresponding to the loading and unloading points of the guide rail 2. A sensor 15 is installed on the mounting bracket 14. The sensor 15 is a photoelectric sensor. The sensor 15 senses the suspension mechanism that has moved to the designated position. When the photoelectric signal is blocked, the drive component 1 stops driving, and the carriage 3 stops moving on the guide rail 2. The equipment is intelligently controlled, which makes it convenient for the staff to load and unload materials.

[0025] In use, the drive assembly 4 is activated, driving the slide 3 to move on the guide rail 2. The sensor 15 senses the suspension mechanism in place. The limit bracket 12 is flipped upward by manual operation to clamp the workpiece between the hangers 7. The limit bracket 12 is slowly released, so that the limit bracket 12 clamps the workpiece against the side of the mounting block 6. After suspension is completed, the drive assembly 4 drives the slide 3 to move on the guide rail 2. It stops moving when it reaches the unloading position. The operator flips the limit bracket 12 to remove the workpiece, which greatly improves the convenience of workpiece suspension and retrieval.

[0026] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the invention is limited to these examples; within the framework of the invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity.
