[0002] In the automated appearance inspection of sensor-welded products, a positioning mechanism is required to hold the product in place during inspection, preventing movement from affecting the inspection results and thus improving inspection accuracy. Traditional clamping and positioning methods typically use rigid grippers. When the product undergoes bending, torsion, or tensile deformation during inspection, this rigid clamping method leads to high stress concentration at the clamping points. This can easily cause hard indentations on the outer sheath of the wire, scratches from the sharp edges of the grippers, or even breakage in extreme cases, directly resulting in product scrap. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a clamping and positioning mechanism for inspecting linear products, which solves the problem that the existing rigid clamping method used in the inspection of welded products of sensor lines is prone to stress concentration and damage to linear products.

[0016] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Various changes can be made to the implementation scheme as long as the effects of the present invention can be achieved.

[0018] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0019] like Figures 1 to 6 As shown in the embodiment of this application, a clamping and positioning mechanism for inspecting linear products is proposed. This clamping and positioning mechanism includes a linear module 1, a connecting frame, and mechanical grippers. Specifically, the connecting frame is fixed to the moving end of the linear module 1, and the mechanical grippers are mounted on the connecting frame. During operation, the linear module 1 drives the mechanical grippers to move linearly in the lateral direction, approaching the root position of the linear product, and directly clamping and positioning the root of the linear product through the mechanical grippers.

[0020] It should also be noted that the linear module 1 is equipped with an assembly plate 2, which is fixed to a fixed object (such as an equipment frame or workbench). To ensure the accuracy of equipment operation, the linear module 1 is preferably a ball screw module, enabling it to accurately deliver the mechanical grippers to the products on the production line. In this embodiment, the mechanical grippers include an electric gripper 5, which is preferably an FSK40XYZ-L type parallel electric gripper.

[0021] In one exemplary embodiment, the connecting frame includes a bracket 3 fixed to the moving end of the linear module 1, and a positioning plate 4 detachably connected to the bracket 3, wherein an electric gripper 5 is fixed to the positioning plate 4. When the linear module 1 moves, the bracket 3 drives the electric gripper 5 to move synchronously, approaching or moving away from the linear product.

[0022] In a preferred embodiment, the bracket 3 has several bolt holes from top to bottom, and the positioning plate 4 is fixed to any longitudinal bolt hole by bolts, thereby adjusting the longitudinal position of the electric gripper 5 on the bracket 3, so that the clamping and positioning mechanism can flexibly adapt to different models or specifications of production line products for clamping and positioning.

[0023] For example, each of the two gripping ends of the electric gripper 5 is fixed with a gripper 6, and a movable sleeve 8 that can move up and down is provided on the opposite surface of the ends of the two grippers 6. When the two grippers 6 are closed, the two movable sleeves 8 on them engage with each other to form a gripping space to grip the production line products.

[0024] To enhance clamping stability, the inner wall of the movable sleeve 8 has several protrusions. These protrusions can be discrete blocks or arc-shaped strips, and their function is to increase the friction with the surface of the product on the production line, preventing slippage or rotation during the inspection process, thereby improving the reliability of clamping.

[0025] In one embodiment, the opposing surfaces of the ends of the grippers 6 have grooves 7 for holding the thread. The aforementioned movable sleeves 8 are disposed in the grooves 7. During implementation, the movable sleeves 8 on the two grippers 6 interlock to form a complete circle in the top view projection, clamping the thread product being inspected. The movable sleeves 8 can also move vertically up and down within the grooves 7. During implementation, when the thread being inspected bends and deforms due to force, the deformation of the thread causes the bottom portion clamped by the movable sleeves 8 to be pulled upward, creating an upward pulling force. At this time, the upward movement of the movable sleeves 8 reduces the pulling force, preventing scratches or breakage of the outer sheath of the thread due to the pulling force.

[0026] In addition, a resistance plate 11 is provided in the groove 7. The material of the resistance plate 11 is preferably a damping plate or a rubber plate. The resistance plate 11 provides stable frictional resistance to the movable sleeve 8 when it moves upward, so that the movable sleeve 8 moves smoothly and slowly during the upward movement, preventing the inertial impact caused by the rapid upward movement of the movable sleeve 8 from causing the line to bear instantaneous impact force.

[0027] Furthermore, a cavity 9 is formed above the groove 7, and the resistance plate 11 is disposed in the cavity 9. The outer wall of the movable sleeve 8 is provided with a side plate 12, which is inserted into the cavity 9 and its outer edge abuts against the resistance plate 11.

[0028] Furthermore, an end cap 10 is fixed to the top of the cavity 9 to cover the cavity 9 and limit the resistance plate 11. The inner edge of the end cap 10 is close to the movable sleeve 8. The cavity 9 is used to allow the side plate 12 to contact the resistance plate 11 and to limit the side plate 12 to prevent the movable sleeve 8 from disengaging from the groove 7.

[0029] The cavity 9 and the side plate 12 include at least two embodiments.

[0030] In the first embodiment, such as Figure 5 As shown, the cavity 9 is T-shaped, and the side plate 12 is adapted to the cavity 9. This arrangement allows the side plate 12 to be engaged in the cavity 9, ensuring the vertical movement of the movable sleeve 8 while preventing it from falling off.

[0031] In the second embodiment, such as Figure 6 As shown, the cavity 9 is semi-circular, and the side plate 12 is adapted to the cavity 9. This arrangement makes the cavity 9 easier to process and assemble. A vertical guide mechanism is provided below the cavity 9, which guides the vertical movement of the movable sleeve 8 and prevents the movable sleeve 8 from falling off.

[0032] Specifically, the vertical guide mechanism includes a cavity 13 and a guide rod 14. The cavity 13 is vertically formed on the gripper 6, with its top facing the cavity 9. The guide rod 14 is fixed to the bottom of the side plate 12 and inserted into the cavity 13. The arrangement of the guide rod 14 inserted into the cavity 13 ensures the vertical movement of the movable sleeve 8 while preventing it from falling off.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
