Description

Technical Field

[0002] High-density lasers can be used to permanently mark the surface of alloy materials for identification purposes, and laser marking machines and material conveying mechanisms are used.

[0003] According to the publication (announcement) number: CN114393321A, the publication (announcement) date: 2022-04-26, a laser marking system for automatic defect location detection is disclosed.

[0004] In the prior art, including the aforementioned patent, the marking process for tubular alloy materials typically involves placing the tubular components one by one at a specific location on a machine tool and marking them sequentially. However, to improve processing efficiency, a continuous conveying mechanism is also used to mark the sidewalls of the tubular components. Before this, a surface defect inspection of the sidewalls of the tubular components is required to ensure that the components themselves are qualified before marking. However, since the continuous conveying mechanism generally only clamps the tubular components horizontally, the entire curved surface of the sidewalls of the tubular components cannot be fully identified by the detection camera. Therefore, the efficiency of surface defect inspection is not high, resulting in defective products among the marked tubular components and affecting the overall pass rate of the batch of tubular components.

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-4 As shown, a laser positioning and correction device for surface defects of alloy materials includes a conveyor belt 1 with an alloy tube 11, and a detection frame 2 is provided on the upper surface of the conveyor belt 1. It also includes a clamping shell 3 fixedly installed on the surface of the conveyor belt 1 and arranged at equal intervals, and a symmetrically arranged rotating ring 4 is rotatably arranged in the clamping shell 3.

[0031] The rotating ring 4 is provided with an arc toothed ring 5 that has radial expansion movement;

[0032] The arc tooth ring 5 is also provided with an elastic band 53 arranged in a circle and deformed and stretched by the insertion and engagement of the alloy tube 11;

[0033] It also includes movable frames 6 that move on both sides of the conveyor belt 1, and toothed rods 61 that mesh with the arc toothed ring 5 are fixedly installed on the movable frames 6.

[0034] Specifically, the conveyor belt 1 is used to circulate the gripping shells 3 on its surface. During this period, a robotic arm or manual labor is used on one side of the conveyor belt 1 to place the alloy tube 11 between the two gripping shells 3. A detection frame 2 with an identification camera is installed at a specific position above the conveyor belt 1. The placement method of the alloy tube 11, the detection method of the detection frame 2 and its electrical connection method, the driving method of the conveyor belt 1 itself, and the subsequent rejection of defective alloy tubes 11 are all existing technologies and will not be described in detail here.

[0035] Furthermore, the arc tooth ring 5 is a combination of arc-shaped racks arranged in a circle, and the rotating ring 4 is located on both sides of the arc tooth ring 5 to ensure the stable rotation of the arc tooth ring 5.

[0036] By placing the alloy tube 11 on a set of clamping shells 3 on the production line of conveyor belt 1, the alloy tube 11 is clamped by the inner wall of multiple arc-shaped toothed racks, and the elastic band 53 is stretched by radial tension, so that the alloy tube 11 is stably clamped until the alloy tube 11 is conveyed to the bottom of the inspection frame 2. At this time, the arc toothed ring 5 meshes with the transmission toothed rod 61, so that the alloy tube 11 rotates under the camera, so that the outer wall of the alloy tube 11 can be covered by the recognition range of the camera, thereby achieving the purpose of efficient judgment. During the process, the alloy tube 11 can also maintain a stable rotation state, improving the recognition accuracy. Afterwards, defective products are removed manually or mechanically to ensure the pass rate of the entire batch of pipe fittings.

[0037] As a further embodiment of this utility model, the inner side of the arc tooth ring 5 is provided with symmetrically arranged rounded surfaces 51.

[0038] By rounding the corners of the inner sidewall of the arc-shaped rack to obtain a rounded surface 51, the alloy tube 11 can be inserted into the arc-shaped gear ring 5 more smoothly and with less resistance.

[0039] As another embodiment further provided in this utility model, the arc tooth ring 5 is also provided with a plurality of arc insertion rods 52 that cooperate with the elastic band 53.

[0040] Specifically, the arc-shaped rack is also provided with arc-shaped holes for the arc-shaped insertion rod 52 to be inserted, and the diameter of the arc-shaped holes is larger than the diameter of the arc-shaped insertion rod 52 in order to accommodate the displacement deviation of the arc-shaped rack. In addition, the multiple arc-shaped racks are non-circular by default, but become circular after clamping the alloy tube 11.

[0041] The arc-shaped insert rod 52 provides support and limit for the elastic band 53, ensuring that the arc-shaped toothed ring 5 formed after the multiple arc-shaped toothed racks are unfolded is regular.

[0042] As another embodiment further provided by this utility model, a side notch 31 is provided on the side of the clamping shell 3 for the movable frame 6 to pass through.

[0043] Specifically, the side notches 31 on the two clamping shells 3 are arranged facing away from each other.

[0044] The side notch 31 ensures that the clamping shell 3 is not disturbed by the movable frame 6 during operation, thus ensuring stable equipment operation.

[0045] As another embodiment provided by this utility model, a symmetrically arranged slider 54 is fixedly installed on the arc tooth ring 5, and a sliding hole 41 is provided on the rotating ring 4 for the slider 54 to slide.

[0046] The sliding hole 41 with a radial movement path ensures stable movement of the arc-shaped rack, facilitating the clamping of the alloy tube 11 after the arc-shaped ring 5 is unfolded.

[0047] As another embodiment of this utility model, the detection frame 2 is fixedly installed with symmetrically arranged side rods 21, and the movable frame 6 is fixedly installed with a driven rod 62 that abuts against the side rods 21.

[0048] Furthermore, the vertically moving lower toothed rod 61 disengages from the meshing arc toothed ring 5.

[0049] Specifically, an electric push rod is fixedly installed on the inspection frame 2. The purpose is to bring the camera close to the alloy tube 11, while still being able to cover the entire outer wall of the alloy tube 11 for identification. This allows the camera to identify inconspicuous defects on the outer wall of the alloy tube 11 more efficiently at close range. The electric push rod and its electrical connection method are existing technologies and will not be described in detail here.

[0050] The side rod 21 moves down synchronously to push the driven rod 62, so that one end of the movable frame 6 equipped with the toothed rod 61 moves in the side notch 31, and the meshing transmission is decoupled, so that the camera can focus on identifying the outer wall of the alloy tube 11 with inconspicuous defects.

[0051] As another embodiment of this utility model, limit frames 7 are also provided on both sides of the conveyor belt body 1, and multiple plug rods 71 ​​that are inserted and slidably connected to the movable frame 6 are fixedly installed on the limit frames 7.

[0052] Specifically, the movable frame 6 has holes for inserting the rod 71.

[0053] Multiple insert rods 71 ​​provide vertical movement guidance for the movable frame 6, ensuring smooth decoupling of the toothed rod 61. The movable frame 6 also has a long rod arranged relative to the toothed rod 61 with the driven rod 62 as the center, which ensures the stable movement of the movable frame 6.

[0054] As another embodiment further provided in this utility model, the limiting bracket 7 is movable in the side notch 31.

[0055] Specifically, the limit frame 7 is fixedly installed on the main housing that provides the conveyor belt 1 for operation, and the main housing is existing technology and will not be described in detail here.

[0056] The side notch 31 is wider than the sum of the ranges of the fixed limit frame 7 and the movable frame 6, which is used to ensure that there is no interference during the operation of the conveyor belt 1.

[0057] As another embodiment of this utility model, a spring located outside the insertion rod 71 is fixedly installed between the limiting frame 7 and the movable frame 6.

[0058] Springs are used to ensure the vertical movement and reset capability of the movable frame 6.

[0059] As another embodiment further provided in this utility model, the elastic band 53 is specifically a rubber tether.

[0060] The use of the rubber elastic band 53 reduces operating costs, and the arc-shaped rack and pinion provides better moving connection.

[0061] Working principle: The alloy tube 11 is placed on a set of clamping shells 3 on the production line of the conveyor belt 1. The inner walls of multiple arc-shaped toothed racks are used to clamp the alloy tube 11. At the same time, the elastic band 53 is stretched by radial tension, so that the alloy tube 11 is stably clamped until the alloy tube 11 is conveyed to the bottom of the detection frame 2. At this time, the arc toothed ring 5 meshes with the transmission toothed rod 61, so that the alloy tube 11 rotates to be below the camera, so that the outer wall of the alloy tube 11 can be covered by the recognition range of the camera, achieving the purpose of efficient judgment.

[0062] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
