Description

Technical Field

[0001] The present invention relates to the field of torsion bar assembly, and in particular to a torsion bar assembly mechanism. Background Art

[0002] With economic and technological development, people's living conditions have improved, and car prices are no longer out of reach. This has led to a surge in the number of private cars, resulting in a rapid growth in the automotive industry. However, with this increase in the number of cars, the number of traffic accidents caused by cars has also increased year by year. Seatbelts are designed to protect drivers and passengers and are a crucial component in ensuring safe driving. When a car collides, brakes suddenly, or tilts, occupants are forced forward or tilted erratically. Seatbelts flexibly and securely secure the body to the seat, protecting it from impact and injury.

[0003] The retractor is the core component of the car seat belt, and the core shaft is the core part of the retractor. The assembly of the core shaft is the key part. The accessories on the core shaft are small in size, and the connection reliability between the components is high. Manual assembly requires the use of tools and takes a lot of time to pick up components, align components, and install components. The manual assembly process results in low efficiency, high cost, and low quality.

[0004] Therefore, the present invention aims to address the deficiencies in the prior art and provide a novel torsion bar assembly mechanism to achieve automatic assembly of the torsion bar. Summary of the Invention

[0023] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0024] Combine Figure 1-Figure 5 As shown, a torsion bar assembly mechanism of the present invention includes a frame 10, a first torsion bar mechanism fixed to the frame 10, a second torsion bar mechanism, an assembly mechanism, and a transfer mechanism 11. The first and second torsion bar mechanisms are used to transfer two torsion bars 12 to the assembly mechanism. The assembly mechanism is used to securely install the two torsion bars 12 together. The transfer mechanism 11 transfers the installed torsion bars 12. The frame is provided with an NG box 13, which is provided with two transfer channels 14. The NG box 14 is used to hold unqualified workpieces to prevent them from flowing into the workstation.

[0025] The first torsion bar mechanism includes a first hoist 15 and a first moving mechanism 16, and the second torsion bar mechanism includes a second hoist 17 and a second moving mechanism 18. The first hoist 15 and the second hoist 17 are both provided with a first detection mechanism. The first hoist 15 and the second hoist 17 are used to transfer different torsion bars 12 one by one to the first detection mechanism. The first detection mechanism realizes the detection of the length of the torsion bar 12, and at the same time facilitates the grasping of the first transfer mechanism 16 and the second moving mechanism 18. Each of the first detection mechanisms includes a placement table 19, a cylinder 20 and a first sensor 21. The cylinder 20 drives the placement table 19 to move back and forth. When it moves to the first elevator 15 and the second elevator 17, it is used to receive the torsion bar 12. Then, when the cylinder 20 drives the placement table 19 to be in the same straight line with the first sensor 21, the first sensor 21 performs a length detection on the torsion bar 12 to detect whether the length of the torsion bar 12 is the same as the preset value. If they are the same, the next step is performed. If they are not the same, the first moving mechanism 16 or the second moving mechanism 18 grabs the torsion bar 12 from the placement table 19 to different transmission pipes 14, and finally flows into the NG box 13.

[0026] The frame 10 is also provided with two second detection mechanisms 22, both of which are arranged close to the first detection mechanism and are used to detect the diameter of the torsion bar 12. When the first detection mechanism completes the detection and the product passes the inspection, the second detection mechanism 22 starts to work, moves to the placement table 19 and clamps the torsion bar 12, thereby measuring the diameter of the torsion bar 12. If the measured diameter is the same as the preset value, the first moving mechanism 16 or the second moving mechanism 18 moves the torsion bar 12 to the assembly mechanism. If the measured diameter is different from the preset value, the first moving mechanism 16 or the second moving mechanism 18 grabs the torsion bar 12 from the placement table 19 to different transmission pipes 14, and finally flows into the NG box 13.

[0027] The assembly mechanism includes a first parallel clamp 23, a second parallel clamp 24, a power source 25 and a fixed seat 26. The first parallel clamp 23 and the second parallel clamp 24 are respectively used to clamp different torsion bars 12. When the torsion bar 12 moves into the first parallel clamp 23 and the second parallel clamp 24 along with the first moving mechanism 16 and the second moving mechanism 17, the first parallel clamp 23 and the second parallel clamp 24 will fix the torsion bar 12 to prevent movement. After fixation, the power source 25 pushes the torsion bar 12 to move toward the fixed seat 26. When the torsion bar 12 contacts the fixed seat 26, the power source 25 applies force again to achieve fixation between the two torsion bars 12.

[0028] A second sensor 27 is provided on the transfer mechanism 11, and a transmission channel 28 is provided below the transfer mechanism 11. The second sensor 27 is used to detect the length of the torsion bar 12 after installation. If the detected length is correct, the transfer mechanism 11 grabs it into the transmission channel 28, thereby transporting it to the next station for installation. If the detected length is incorrect, the transfer mechanism 11 grabs it into the nearby transmission pipe 14, and finally flows into the NG box 13 for scrapping, to prevent it from flowing into the next station and causing more workpieces to be scrapped.

[0029] Preferably, the rack 10 is further provided with a storage table 29 and a cleaning barrel 30. The storage table 29 is used to place torsion bars 12 of different specifications. When the torsion bar 12 needs to be tested, the torsion bar 12 on the storage table 29 is grabbed to complete the test of the set value to prevent errors from occurring, resulting in the production of wrong parts and unnecessary waste. The cleaning barrel 30 is provided with two openings 31. The two openings 31 are arranged near the first hoist 15 and the second hoist 17. When the product needs to be changed, the torsion bar 12 transmitted on the first hoist 15 and the second hoist 17 needs to be replaced. Therefore, the existing torsion bar 12 will be transmitted to the opening 31 and then flow into the cleaning barrel 30. This design makes it more convenient to replace products, improves efficiency, and avoids the danger of manually taking out the torsion bar.

The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
