[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figure 1-4 A quality inspection device for the production of a rewinder assembly includes a base plate 1, a clamping assembly is provided on one side of the upper end of the base plate 1, a winding force detection assembly is provided on one side of the clamping assembly, and a locking test assembly is provided on the other side of the clamping assembly.

[0023] The winding force detection assembly includes an L-shaped mounting plate 2. A torque sensor 8 is installed on one side of the vertical section of the L-shaped mounting plate 2. A servo motor 5 is installed on the horizontal section of the L-shaped mounting plate 2. The output end of the servo motor 5 is connected to one end of the torque sensor 8 through a coupling. A flange 15 is connected to the other side of the torque sensor 8 through a coupling. Slot holes 4 are opened on both sides of the horizontal section of the L-shaped mounting plate 2. Hexagon socket bolts 3 are inserted into both slot holes 4. Both hexagon socket bolts 3 are screwed to the base plate 1.

[0024] The clamping assembly includes a fixed rod 11 fixed to the upper end of the base plate 1. A curved clamping rod 9 is hinged to the middle of one side of the fixed rod 11. An electric push rod 10 is rotatably mounted between one end of the curved clamping rod 9 and one end of the fixed rod 11.

[0025] The other end of the fixing rod 11 is provided with a limit slot 16 facing the curved clamp rod 9.

[0026] An information processing module 12 is installed on the upper surface of the seat plate 1, and the information processing module 12 is electrically connected to the torque sensor 8. A display screen is integrated on the information processing module 12.

[0027] A control switch 13 is provided on the upper surface of the base plate 1 and on one side of the information processing module 12.

[0028] The retractor is placed in the limiting slot 16 of the fixed rod 11. The curved clamp rod 9 is rotated by the electric push rod 10, and then the retractor is clamped by the curved clamp rod 9. The position of the L-shaped mounting plate 2 is finely adjusted so that the flange 15 is close to the end of the retractor's spool. The flange 15 is then connected to the end of the retractor's spool. The hex bolts 3 are then tightened to fix the L-shaped mounting plate 2. The torque sensor 8 and the retractor's spool are rotated by the servo motor 5, so that the free end of the seat belt is released. During the rotation, the torque sensor 8 detects the winding force fed back by the retractor's spool and transmits the detected value to the information processing module 12 for analysis and processing, and records it. Multiple tests can be performed, and the obtained winding force data is analyzed to calculate statistical parameters such as the average value and standard deviation. The average value can reflect the overall level of the winding force.

[0029] Example 2 is an optimization based on Example 1, specifically:

[0030] The locking test assembly includes a guide rail 7 fixed to the upper surface of the base plate 1. A T-shaped groove 22 is provided at one top end of the guide rail 7. A T-shaped slider 23 is slidably engaged in the T-shaped groove 22. The top end of the T-shaped slider 23 extends above the guide rail 7 and is connected to a U-shaped rope clip 20. A sleeve 19 is fixed at the top of the guide rail 7 and on one side of the T-shaped slider 23. A push rod 21 is movably inserted into the sleeve 19. An air release valve 18 is installed at the sealed end of the sleeve 19, and an air pipe 6 is connected to one side of the sealed end of the sleeve 19. One end of the air pipe 6 is connected to an air compressor. A U-shaped limit clip 17 is fixed at the end of the T-shaped groove 22. By setting the U-shaped limit clip 17, the T-shaped slider 23 is prevented from disengaging from the T-shaped groove 22. A valve 14 is provided on the air pipe 6 and the valve 14 is fixed on the base plate 1.

[0031] Pull the free end of the seat belt out from the retractor and insert the seat belt into the U-shaped limit clip 17. The buckle of the free end of the seat belt abuts against the outside of the U-shaped limit clip 17, simulating the seat belt being pulled out during normal use. During the test, the valve 14 is opened quickly, so that the high-pressure air in the air compressor enters the sleeve 19 instantly along the air pipe 6, thereby causing the high-pressure air to push the push rod 21 out quickly. The push rod 21 hits the T-shaped slider 23. Observe whether the T-shaped slider 23 slides along the T-shaped groove 22 to pull out the seat belt. If the seat belt is pulled out, it means that the locking function of the retractor is ineffective.

[0032] By releasing the air from the sleeve 19 through the vent valve 18, the push rod 21 can be reset, allowing for the next test.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
