The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components.

[0033] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention.

In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0034] In the automated production of automotive pressure ring welding, the positioning accuracy of the weld seam directly affects the subsequent grinding and welding quality. Traditionally, the positioning of the weld seam is achieved by manually stacking materials on trays, manually loading and unloading materials, and visually identifying the weld seam position. This method is not accurate enough and is inefficient, resulting in a high product scrap rate. It also causes problems such as time-consuming changeovers and material waste. Existing equipment cannot meet the requirements for efficient and high-precision positioning. Therefore, a high degree of automation, adaptability to multiple models, and high positioning accuracy rapid positioning device for pressure ring weld seams is needed to improve production efficiency and welding quality, and reduce operational complexity and product scrap rate.

[0035] Please see Figures 1 to 5 , Figure 1A rapid weld seam positioning device according to an embodiment of the present invention includes a worktable 100, a limiting unit 200, a clamping drive unit 300, a detection unit 400, and a control unit. The worktable 100 is inclined, allowing the workpiece to slide along the inclined worktable 100 into the limiting unit 200 and slide within the limiting area formed by the limiting unit 200 to avoid displacement. The clamping drive unit 300 includes a clamping part and a driving part. The driving part drives the clamping part to move or rotate according to the control unit signal, thereby the first rotating wheel 310 and the second rotating wheel 320 of the clamping part cooperate to press the inner and outer sides of the workpiece, and drive the workpiece to rotate through rotation. The detection unit 400 performs weld seam detection and positioning during the workpiece rotation, achieving fully automatic high-precision positioning. The overall structure is simple, stable, and the components are easy to adjust and replace. It can adapt to the production of different types of workpieces, shorten changeover time, and achieve high detection accuracy, enabling efficient automated detection and positioning.

[0036] Please see Figures 1 to 5 In one optional embodiment, the worktable 100 is tilted, and the clamping drive unit 300 and the detection unit 400 are mounted on the worktable 100. After the workpiece completes the previous process, it is transported to the worktable 100 for weld seam detection and positioning. Then, it is picked up by a robot and enters the next process. At the same time, the next workpiece continues to enter the worktable 100 for weld seam detection and positioning. During continuous detection, the first rotating wheel 310 and the second rotating wheel 320 of the clamping drive unit 300 cooperate to press the workpiece on both the inner and outer sides of the workpiece and drive it to rotate for weld seam detection. The worktable 100 is provided with a through hole, and the clamping drive unit 300 can pass through the through hole from the bottom to clamp the workpiece without affecting the operation of the detection unit 400 above. It can also automatically avoid obstacles during continuous detection to ensure that the workpiece continuously enters the worktable 100 and ensures the stability of the production cycle.

[0037] Please see Figures 1 to 5 In one optional embodiment, the limiting unit 200 is disposed on the worktable 100 and forms a limiting area. The workpiece slides within the limiting area and is automatically corrected by the limiting unit 200, so that the workpiece can quickly slide to the designated position. The entire positioning process is fast and stable, ensuring the high efficiency of the automated production process. The through hole is located at the end of the limiting unit 200. After the workpiece moves to the end of the limiting unit 200, it is kept stable and rotated under the clamping drive unit 300. During the rotation, the weld is detected and positioned by the detection unit 400.

[0038] Please see Figures 1 to 5In an optional embodiment, the limiting unit 200 includes limiting brackets 210 symmetrically arranged on both sides of the through hole, forming a guide channel with a gradually narrowing opening width. Each limiting bracket 210 includes a first end and a second end. The first end is located at the end of the worktable 100, and the second end extends inwards towards the worktable 100. The opening width of the first end is greater than the opening width of the second end. For example, the limiting bracket 210 includes two stainless steel plate-shaped brackets. The opening width of the first end can be adapted to the width of the worktable 100, ensuring sufficient space is left at the first end for the workpiece to enter. The opening width of the second end... The width of the opening can be determined according to the workpiece model. After the workpiece is conveyed to the worktable 100 from the previous process, due to the inclined setting of the worktable 100, the workpiece slides from the wide opening end to the narrow opening end. During this process, the lateral component force applied by the gradually narrowing inner wall automatically corrects the positional offset, eliminates manual stacking errors, and improves positioning stability. The restriction of the narrow opening end allows the position of the workpiece to automatically adapt to the position of the through hole and the clamping drive unit 300 after sliding to the second end. Then, the clamping drive unit 300 is used to clamp the workpiece, ensuring the speed and accuracy of the entire process and improving automation efficiency. In other embodiments, a groove structure can also be used on the worktable 100 as a limiting unit 200 to guide the workpiece alignment, etc.

[0039] Please see Figures 1 to 5 In an optional embodiment, an adjusting member 220 is also provided on one side of the limiting bracket 210. The adjusting member 220 is arranged near the second end and has an arc-shaped groove. The fixing member passes through the arc-shaped groove to press and fix the limiting bracket 210 onto the worktable 100. When installing the limiting bracket 210, one end is connected to the worktable 100 by bolts, and the other end is, for example, passed through the arc-shaped groove by bolts and pressed and fixed by nuts. The structure is stable and the opening size of the second end of the limiting bracket 210 can be freely adjusted to adapt to various different types of workpieces. When changing the workpiece model, simply loosen the bolts and nuts at both ends, and the second end of the limiting bracket 210 can be adjusted by rotation to adjust the opening size. After adjusting to the appropriate position, the fixing members at both ends can be tightened to fix it.

[0040] Please see Figures 1 to 5 In an optional embodiment, the clamping drive unit 300 includes a clamping part and a drive part. The clamping part includes a first rotating wheel 310 disposed on both sides of the through hole and a second rotating wheel 320 that can pass through the through hole. The drive part includes a first drive part 330 and a second drive part 340. The first drive part 330 drives the first rotating wheel 310 and / or the second rotating wheel 320 to rotate to drive the workpiece to rotate. The second drive part 340 drives the second rotating wheel 320 to move vertically and horizontally relative to the worktable 100 to clamp or release the workpiece. When the first rotating wheel 310 abuts against the outer side of the workpiece and the second rotating wheel 320 abuts against the inner side of the workpiece, the two cooperate to press the workpiece and drive it to rotate, thereby realizing the detection of the weld position.

[0041] Please see Figures 1 to 5 In one optional embodiment, after the workpiece is in place, two first rotating wheels 310 are symmetrically distributed on both sides of the workpiece. The second rotating wheel 320 is designed with a wheel diameter smaller than the inner diameter of the workpiece. Under the action of the second drive unit 340, it performs a compound motion. It moves vertically through the through hole of the worktable 100 and enters the inner ring cavity of the workpiece. It moves horizontally towards the direction of the first rotating wheel 310 and works with the first rotating wheel 310 to press the inner and outer sides of the workpiece. The wheel surface width of the second rotating wheel 320 is greater than the thickness of the workpiece to ensure that the inner ring contact surface is fully wrapped and to provide reliable pressing force. After the workpiece is fixed, the first rotating wheels 310 on both sides rotate synchronously, driving the pressure ring workpiece to rotate through friction transmission. At this time, the second rotating wheel 320 rotates as a driven wheel, maintaining stable pressing while ensuring smooth rotation. During the rotation, the detection unit 400 performs real-time weld position scanning. After the detection is completed, the second rotating wheel 320 retracts horizontally and disengages from the inner ring of the workpiece, then descends vertically and resets to the position below the worktable 100. While the robot arm picks up the positioned workpiece, the next workpiece slides into the workstation along the inclined worktable 100. The avoidance action of the second rotating wheel 320 ensures continuous production cycle, realizes uninterrupted input and detection of workpieces, and supports the operation of a highly efficient automated production line.

[0042] Please see Figures 1 to 5 In one optional embodiment, the first driving unit 330 includes a rotary driving member 331, which is connected to the first rotating wheel 310 via a transmission member 332, driving the first rotating wheel 310 to rotate. Specifically, the driving member is, for example, a servo motor, and the transmission member 332 is a synchronous belt. The servo motor drives the two first rotating wheels 310 to rotate in the same direction via the synchronous belt, thereby driving the workpiece and the internal second rotating wheel 320 to rotate. The synchronous belt tension adjustment mechanism ensures that there is no slippage in the transmission and that the linear speed of the workpiece rotation is stable. In other embodiments, the transmission member 332 can also be a gear set or other structure, as long as it can achieve the synchronous rotation of the first rotating wheel 310.

[0043] Please see Figures 1 to 5In one optional embodiment, the second drive unit 340 includes a horizontal drive member 341 and a vertical drive member 342. The horizontal drive member 341 is fixed to the bottom of the worktable 100, and its output end is connected to the vertical drive member 342 through a connector 343. The output end of the vertical drive member 342 is connected to the workpiece. Specifically, the horizontal drive member 341 is a horizontal cylinder, and the vertical drive member 342 is a vertical cylinder. The vertical cylinder is fixed to the connector 343, and its piston rod is connected to the shaft seat of the second rotating wheel 320, which can push the second rotating wheel 320 to move vertically relative to the worktable 100. The horizontal cylinder pushes the connector 343 to move horizontally relative to the worktable 100. The two work together to control the combined action of lifting and moving forward of the second rotating wheel 320, resulting in fast pressing action response, good stability, and high working efficiency. In other embodiments, the second drive unit 340 can be connected to the output end of the horizontal cylinder, and the vertical cylinder can be fixed to the worktable 100 and connected to the horizontal cylinder through the connector 343. The drive unit can also adopt the structure of a linear motor and a ball screw, which can realize the lifting and forward movement of the second rotating wheel 320.

[0044] Please see Figures 1 to 5 In an optional embodiment, the connector 343 is connected to the worktable 100 via a guide assembly, which includes a guide rail 110 and a slider 3431 that slide against each other. The guide rail 110 is located at the bottom of the worktable 100, and the slider 3431 is located on the connector 343. Furthermore, a self-lubricating bearing can be provided inside the slider 3431 to ensure the straightness error of the movement trajectory of the second rotating wheel 320. When the horizontal cylinder is activated, it pushes the connector 343 to move horizontally along the guide rail 110. The action is fast, precise, and stable, ensuring that the workpiece is clamped without being damaged, thus guaranteeing the reliability and efficiency of the working process.

[0045] Please see Figures 1 to 5 In one optional embodiment, the detection unit 400 includes a colorimetric sensor 410 disposed on the side of the workpiece and a vision positioning component 420 disposed above the workpiece, performing weld detection and positioning when the workpiece rotates. The colorimetric sensor 410 is disposed on one side and achieves rapid initial positioning by identifying the color difference between the weld and the base material. Meanwhile, the vision positioning component 420 above the workpiece includes a light source and an industrial camera. Specifically, for example, a ring LED light source and an integrated industrial camera can be used. The light source coaxially illuminates the weld area, providing good environmental adaptability. The camera acquires images and processes them to complete fine positioning. Through dual detection and positioning, the weld positioning error is ensured to be ≤0.02mm, significantly improving positioning accuracy and efficiency, reducing product defect rate, and improving grinding quality. After positioning is completed, the robot arm picks up the workpiece and transfers it to the grinding process.

[0046] Please see Figures 1 to 5In one optional embodiment, the control unit is communicatively connected to the detection unit 400 and the drive unit, and controls the drive unit to operate in response to signals from the detection unit 400. Specifically, during the detection process, the control unit receives signals from the color sensor 410 (initial positioning trigger) and coordinate data from the industrial camera (fine positioning coordinates and offset). Through coordinated control of the drive unit, it stops the rotation of the servo motor in response to the signal from the color sensor 410. It can also control the servo motor to fine-tune the workpiece rotation angle based on the weld coordinate signal from the camera to compensate for the offset, ensuring accurate positioning. During the workpiece positioning and gripping process, after receiving the workpiece arrival signal, the control unit controls the vertical cylinder to lift the second rotating wheel 320 and the horizontal cylinder to push forward and press. After the detection is completed, it controls the horizontal cylinder to retract and the vertical cylinder to descend and avoid the obstruction. The device can also be equipped with arrival sensors and pressure sensors to provide feedback on the workpiece position and clamping force, achieving safe, accurate, and rapid control.

[0047] Please see Figures 1 to 5 In one optional embodiment, after the workpiece leaves the previous process, it enters the workbench 100 and slides along the inclined workbench 100 into the gradually narrowing limiting bracket 210. After the workpiece is in place, the positioning sensor triggers the vertical cylinder to lift the second rotating wheel 320 and the horizontal cylinder to push the second rotating wheel 320 to press the inner ring of the workpiece. The servo motor drives the first rotating wheel 310 to rotate the workpiece. During the rotation, the color sensor 410 identifies the color difference of the weld and takes a picture with an industrial camera for precise positioning. After the weld position is determined, the rotation stops, the double cylinder retracts the second rotating wheel 320, and at the same time the robot arm picks up the material, and the next workpiece enters, repeating the above process.

[0048] In summary, the weld seam rapid positioning device of this utility model, with its tilting worktable 100 and gradually narrowing limiting bracket 210, enables automatic workpiece entry and position correction. Combined with the dual-wheel cooperative clamping drive, it can adapt to multiple models of pressure rings, has good compatibility, and effectively shortens changeover time. With the dual high-precision detection of color sensor and vision component, it achieves fully automatic rapid positioning of weld seams, improving product quality. Combined with the intelligent lifting and avoidance design of the second rotating wheel, it ensures continuous production cycle, improves efficiency and capacity, guarantees accurate weld seam positioning, and can achieve seamless switching between multiple models, significantly improving production efficiency and realizing full-process automation. The device has a simple structure, good stability, and solves the problems of large errors, poor compatibility, and low efficiency of manual positioning.
