Description

Technical Field

[0001] This invention belongs to the field of welding technology, specifically a pre-positioning welding integrated device for fork hooks. Background Technology

[0002] A fork hook is a key structural component installed on the forklift forks to achieve a connection function. During the manufacturing process, fork hooks are often fixed to the forks by welding.

[0003] In existing technologies, the automated welding of fork hooks and forks typically employs a collaborative approach between a welding robot and a loading robot. The loading robot picks up the fork hooks and forks from the production line, places them in a designated position, and joins them together. Subsequently, the welding robot welds the joint.

[0004] However, in actual production, there are significant differences in the feeding methods for forks and fork hooks. Because forks are large and heavy, they are usually arranged in an orderly manner in a dedicated box for easy handling and gripping, and the entire box of forks is delivered to the welding station manually or by AGV. Fork hooks, on the other hand, are relatively small, and each fork typically requires the welding of multiple hooks, resulting in a large number of hooks and making them difficult to organize. Therefore, in actual production, hooks are often piled up randomly in collection boxes or transported in a disorderly manner via conveyor lines.

[0005] Although the loading robot is equipped with a vision positioning system to assist in gripping the workpiece, when the hooks are fed in an disordered manner, the vision system cannot guarantee that it can accurately identify and stably grasp the workpiece every time. The gripping accuracy and positioning accuracy are easily affected by factors such as messy hook postures and stacking obstruction, which in turn reduces the welding quality and hinders the continuous and stable progress of welding operations.

[0020] Preferably, it includes a uniformly distributed auxiliary component;

[0021] The uniform distribution auxiliary component includes two winding rollers, on which a filling cloth is wound.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. The fork hook pre-positioning welding integrated equipment of the present invention utilizes a hook pre-positioning auxiliary component. During the entire welding process, multiple hooks can be separated and arranged in a line on the conveyor belt. The hooks to be clamped have only four orientation states. The loading robot can accurately clamp the hooks according to the preset path, avoiding the impact of factors such as messy hook postures and stacking obstruction on clamping accuracy and positioning accuracy, thereby ensuring welding quality and continuous and stable welding operation.

[0026] 3. The fork hook pre-positioning welding integrated equipment of the present invention utilizes uniformly distributed auxiliary components. When the hook is on the upper surface of the flip plate, the flip plate can be rotated back and forth in a regular manner. The hook on the flip plate will slide to both sides, so that multiple hooks are evenly distributed on the flip plate. The hooks can slide from multiple areas to the rectangular placement surface, thereby making reasonable use of the placement area of ​​the rectangular placement surface, which is conducive to improving the feeding speed and continuous welding efficiency.

[0027] In addition, when the flip plate rotates, its ends will pull the filling cloth on both sides to move. At the same time, the winding roller rotates and the spring deforms, so that the filling cloth can fill the gaps on both sides of the flip plate caused by the rotation, preventing the hook from falling out through the gaps.

[0050] like Figure 2 and Figure 7 As shown, it includes a height-limiting push-down component;

A cylinder 26 is fixedly connected to one side of the outer wall of the feeding frame 5. The piston end of the cylinder 26 is fixedly connected to one side of the push plate 15.

[0052] Specifically, in existing technologies, when automating the welding of fork hooks and forks, a welding robot 3 and a loading robot 2 typically work together. The loading robot 2 picks up the fork hooks and forks from the production line, places them in the designated position and joins them together, and then the welding robot 3 welds the joint.

[0053] However, in actual production, there are significant differences in the feeding methods for forks and fork hooks. Because forks are large and heavy, they are usually arranged in an orderly manner in a dedicated box for easy handling and gripping, and the entire box of forks is delivered to the welding station manually or by AGV. Fork hooks, on the other hand, are relatively small, and each fork typically requires the welding of multiple hooks, resulting in a large number of hooks and making them difficult to organize. Therefore, in actual production, hooks are often piled up randomly in collection boxes or transported in a disorderly manner via conveyor lines.

[0054] Although the loading robot 2 is equipped with a vision positioning system to assist in gripping workpieces, when the hooks are fed in an disordered manner, the vision system cannot guarantee that it can accurately identify and stably grasp the workpieces every time. The gripping accuracy and positioning accuracy are easily affected by factors such as messy hook postures and stacking obstruction, which in turn reduces the welding quality and hinders the continuous and stable progress of welding operations.

[0055] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0056] This solution is applied to welding fork hooks and forks of the same specifications in the same batch, where both the fork hooks and forks are L-shaped, and the length of the hook's long and short arms is greater than its own width.

[0057] First, the box containing multiple forks is placed on the support plate 36. The loading robot 2 picks up the forks from the box and places them on the welding table 4, with the bottom of the forks positioned between clamping block 1 34 and clamping block 2 35. Then, the cylinder 6 33 drives clamping block 1 34 to move laterally, thus fixing the forks in place under the action of clamping block 1 34 and clamping block 2 35.

[0058] Since the upper surfaces of pallet 17 and pallet 28 cooperate to form a rectangular placement surface for supporting the hook, the width of the placement surface can be adjusted by using cylinder 3 25 to slide pallet 28 on pallet 17 according to the length of the hook's short arm. This width is made the same as the length of the hook's short arm. Furthermore, when pallet 28 moves, cylinder 1 6 moves the material placement plate 7, keeping one edge of the material placement plate 7 in contact with the surface of pallet 28. Similarly, cylinder 5 28 moves the baffle 12 laterally, adjusting the distance between one end face of the baffle 12 and the upper edge of the loading frame 5, ensuring this distance is also equal to the length of the hook's short arm.

[0059] After the above adjustments are completed, connect one end of the chain conveyor 1 to the hook conveyor line, or pour all the hooks from the collection box onto the chain conveyor 1. Then, the chain conveyor 1 transports the hooks to the upper material frame 5 and onto the tilting plate 8. Because the tilting plate 8 is tilted, the hooks will slide down the surface of the tilting plate 8 under the action of gravity until they are blocked by one side of the upper material frame 5. Initially, the rectangular placement surface is aligned with the surface of the material plate 7, so some hooks will fall onto the rectangular placement surface. Then, the lifting rod 16 is raised by the cylinder 37, and the rectangular placement surface will also rise accordingly. Since the width of the rectangular placement surface is equal to the length of the short arm of the hook, the hook can only be stably supported by the rectangular placement surface when the long arm of the hook is completely within the area of ​​the rectangular placement surface. Otherwise, the hook will fall off the rectangular placement surface due to imbalance. This is the first screening of the hook orientation.

[0060] As the rectangular placement surface rises, it stops rising when the distance between the rectangular placement surface and the bottom edge of the push plate 15 is equal to the width of the hook. At this point, cylinder 4 26 drives the push plate 15 to move laterally until the push plate 15 has completely passed the rectangular placement surface. Since the distance between the rectangular placement surface and the bottom edge of the push plate 15 is equal to the width of the hook, if the hook is upright or overlapped, it will be dislodged by the push plate 15. At this point, only the flat hooks are on the rectangular placement surface, and the long arm of the hook is aligned with the length of the rectangular placement surface. The hooks are arranged in a straight line on the rectangular placement surface, which is the second screening.

[0061] Then, the push plate 15 resets, and the rectangular placement surface continues to rise. When the rectangular placement surface reaches the upper edge of the loading frame 5, the hooks on the rectangular placement surface will slide towards the conveyor belt 11 due to the removal of the obstruction from the inner wall of the loading frame 5. Since the distance between the baffle 12 and the upper edge of the loading frame 5 is equal to the length of the hook's short arm, multiple hooks will still be placed on the conveyor belt 11 in a straight line. The conveyor belt 11 drives the multiple hooks to move until the hooks are blocked by the stop block 29. At this time, the hooks on the conveyor belt 11 have only four orientations. The orientation of the hook blocked by the stop block 29 can be identified by the vision sensor 14, and the orientation information is uploaded to the control system of the loading robot 2. The loading robot 2 can then accurately pick up a single hook according to the preset path, adjust the hook to a suitable angle according to the orientation information, and then splice the hook with the fork. At this time, the welding robot 3 can weld the joint between the hook and the fork. Then repeat the above operation. As the rectangular placement surface continuously pushes the hooks onto the conveyor belt 11, the loading robot 2 can continuously clamp multiple hooks and splice them with the forks. After welding, the loading robot 2 places the welded forks into the collection box.

[0062] Throughout the welding process, with the help of the hook pre-positioning auxiliary component, multiple hooks can be separated and arranged in a line on the conveyor belt 11. The hooks to be picked up have only four orientation states. The loading robot 2 can accurately pick up the hooks according to the preset path, avoiding the impact of hook posture disorder, stacking and obstruction on the picking accuracy and positioning accuracy, thereby ensuring the welding quality and the continuous and stable progress of the welding operation.

[0063] Example 2:

[0064] like Figure 5 and Figure 6 As shown, it includes an integrated component for material lifting assistance and anti-jamming;

[0065] The integrated lifting and anti-jamming component includes a connecting plate 21. Multiple rotating columns 19 are rotatably arranged on one side of the connecting plate 21, and the bottom of the support plate 2 18 is provided with through holes through which the multiple rotating columns 19 can pass.

[0066] like Figure 6 As shown, a cylinder 20 is fixedly connected to one side of the support plate 21. The piston end of the cylinder 20 is fixedly connected to one side of the connecting plate 21. A worm wheel 24 is fixedly connected to one end of the rotating column 19. The worm wheel 24 is rotatably mounted on the connecting plate 21. A worm 22 is rotatably mounted at both ends on one side of the connecting plate 21. The worm 22 has multiple worm teeth, and each worm tooth meshes with a worm wheel 24. A motor 23 is fixedly connected to one side of the connecting plate 21. The output end of the motor 23 is fixedly connected to one end of the worm 22.

[0067] Specifically, in the above embodiments, although the hooks can be arranged and fed onto the conveyor belt 11 in cooperation with the rectangular placement surface and the feeding frame 5, if some hooks continue to have only their ends resting on the rectangular placement surface, they will not be able to be lifted, thus affecting subsequent feeding operations. In addition, when multiple hooks are clustered on the tilting plate 8, the hooks are prone to getting stuck on the tilting plate 8, thus affecting the normal sliding of the hooks, which also affects subsequent normal feeding.

[0068] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0069] Whenever the rectangular placement surface is flush with the upper edge of the feeding frame 5, the rotating column 19 will be higher than the upper surface of the flip plate 8. At this time, some hook ends will be in contact with the surface of the rotating column 19. Then, the motor 23 drives the worm gear 22 to rotate, and under the transmission of the worm gear 22 and worm wheel 24, multiple rotating columns 19 will rotate simultaneously. The friction between the rotating column 19 and the hook will cause the hook to deflect, thereby actively changing the angle of the hook. After the rectangular placement surface is reset, the hook can more easily slide onto the rectangular placement surface in the correct posture. At the same time, when the rotating column 19 contacts the hook, the cylinder 20 can drive the connecting plate 21 to move, so that multiple rotating columns 19 pass through the through hole at the bottom of the support plate 18, which can push the hook in the opposite direction of the sliding direction, thereby clearing the stuck hook. Thus, under the action of the rotation of the rotating column 19 and the pushing action, the hook can more easily slide onto the rectangular placement surface in the correct posture, further ensuring the stable progress of subsequent feeding operations.

[0070] Example 3:

[0071] like Figure 2 , Figure 9 , Figure 10 As shown, it includes uniformly distributed auxiliary components;

[0072] The uniform distribution auxiliary component includes two winding rollers 30, with a filling cloth 32 wound around the winding rollers 30. The filling cloth 32 slides through one side of the material placement plate 7, and the ends of the two filling cloths 32 are respectively fixedly connected to the two sides of the flip plate 8.

[0073] like Figure 2 , Figure 9 , Figure 10 As shown, a motor 9 is fixedly connected to one side of the material placement plate 7. The output end of the motor 9 is fixedly connected to one side of the flipping plate 8. A spring 31 is sleeved on one end of the winding roller 30. One end of the spring 31 is fixedly connected to the end of the winding roller 30, and the other end is fixedly connected to the inner wall of the material placement plate 7.

[0074] Specifically, in the above embodiments, although the hooks can slide along the flip plate 8 to the rectangular placement surface, when multiple hooks are on the upper surface of the flip plate 8, they are prone to local accumulation. As a result, multiple hooks can only slide from a fixed range to the rectangular placement surface, and the area of ​​the rectangular placement surface cannot be reasonably utilized, which restricts the feeding speed to a certain extent and affects the continuous welding efficiency.

[0075] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0076] When the hook is on the upper surface of the flip plate 8, the flip plate 8 can be driven by the motor 9 to rotate back and forth in a regular manner. The hook on the flip plate 8 will slide to both sides, so that multiple hooks are evenly distributed on the flip plate 8. The hook can slide from multiple areas to the rectangular placement surface, thus making reasonable use of the placement area of ​​the rectangular placement surface, which is conducive to improving the feeding speed and continuous welding efficiency.

[0077] In addition, when the flip plate 8 rotates, its ends will pull the filling cloth 32 on both sides to move. At the same time, the winding roller 30 rotates and the spring spring 31 deforms. The filling cloth 32 can fill the gaps on both sides of the flip plate 8 caused by the rotation, preventing the hook from falling out through the gap.

[0078] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
