Technical Field

[0001] The invention belongs to the technical field of seat belt retractor production equipment, and in particular relates to a noise reduction ring installation device for a seat belt retractor. Background Art

[0002] The noise reduction ring of a seat belt retractor is a component used to reduce the noise generated by the seat belt retractor during operation. It is generally installed around the reel, the core mechanical component of the retractor, and is adjacent to the gear set, ratchet mechanism, etc. inside the retractor; it controls the noise generated by actions such as the rotation of the reel, the engagement of the gears, and the locking and releasing of the ratchet.

[0003] Noise reduction rings play an important role in automobile safety systems. First, during the driving of the vehicle, if the seat belt retractor generates noise, it will interfere with the driver and passengers, affecting the driving experience and ride comfort; the noise reduction ring can effectively reduce this noise and make the interior environment of the vehicle quieter; for example, during long-distance driving, a quiet interior environment can allow the driver to be more focused and reduce fatigue. Secondly, automobile manufacturers have strict requirements for the NVH (noise, vibration and harshness) performance of the vehicle; the noise reduction ring of the seat belt retractor is an important part of meeting these quality standards. If the retractor noise is too loud, it may cause the overall NVH performance of the vehicle to fail to meet the standards, affecting the vehicle's market competitiveness.

[0004] The existing technology blindly installs the noise reduction ring in the seat belt retractor. Due to the influence of the mutual contact between the belt sensor component, vehicle sensor component and lock cover component in the seat belt retractor, the noise reduction ring is easily installed out of position, affecting production efficiency and product quality.

[0007] A storage and delivery module, storing the noise reduction ring and delivering the noise reduction ring;

[0008] A monitoring module, monitoring the position and circumferential angle of the noise reduction ring;

[0009] a clamping and adjusting module, clamping the noise reduction ring delivered by the storage and delivery module, and adjusting the circumferential angle of the noise reduction ring according to the circumferential angle of the noise reduction ring monitored by the monitoring module; a cone cover is provided on the clamping and adjusting module, and when the clamping and adjusting module clamps the noise reduction ring, the cone cover is located at the center of the noise reduction ring;

[0010] a transfer module, configured to transfer the clamping and adjusting module according to the position of the noise reduction ring monitored by the monitoring module;

[0011] A turntable module is provided with the seatbelt retractor body, the transfer module transfers the clamping adjustment module to the top of the turntable module, and the turntable module rotates;

[0013] As described above, the noise reduction ring installation device for a seat belt retractor of the present invention has at least the following beneficial effects:

[0014] The noise reduction ring installation equipment of this seat belt retractor realizes the automation of noise reduction ring installation through the design of mutual cooperation between the storage and conveying module, the clamping and adjustment module, the transfer module, the assembly module and the assembly module, thereby improving the overall production efficiency of the seat belt retractor; at the same time, the position and circumferential angle of the noise reduction ring are monitored by the monitoring module, the circumferential angle of the noise reduction ring is adjusted by the clamping and adjustment module, and the position of the noise reduction ring is adjusted by other modules.

[0029] The following embodiments are for illustration only and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0030] See also Figure 1 The present invention provides a device for installing a noise reduction ring of a seat belt retractor. The device uses an automated method to install the noise reduction ring 21 of a car seat belt retractor. Compared with the prior art of blindly installing the noise reduction ring 21 in the seat belt retractor, the device significantly improves the installation efficiency and quality. The device includes:

[0031] like Figure 1 The storage and conveying module 11 shown stores the noise reduction ring 21 and conveys the noise reduction ring 21 out. The storage and conveying module 11 selects a structure of a combination of a vibration plate and a straight vibration track, and the specific content will be introduced in the following embodiments.

[0032] like Figure 1 The monitoring module shown monitors the position and circumferential angle of the noise reduction ring 21 .

[0033] like Figure 1 and Figure 3 The clamping and adjustment module 12 shown clamps the noise reduction ring 21 transported out by the storage and conveying module 11, and adjusts the circumferential angle of the noise reduction ring 21 according to the circumferential angle of the noise reduction ring 21 monitored by the monitoring module; a cone cover 124 is provided on the clamping and adjustment module 12, and when the clamping and adjustment module 12 clamps the noise reduction ring 21, the cone cover 124 is located at the center of the noise reduction ring 21.

[0034] like Figure 1 The transfer module 13 shown moves the clamping and adjusting module 12 clamping the noise reduction ring 21 to a designated position according to the position of the noise reduction ring 21 monitored by the monitoring module.

[0035] like Figure 1 The turntable module 14 shown is installed with the body of the seat belt retractor, which includes a frame, a belt sensor component 22 and a core shaft. The belt sensor component 22 is located above the frame of the seat belt retractor, and the core shaft of the seat belt retractor passes through the center of the belt sensor component 22.

[0036] like Figure 1 and Figure 3 The assembly module 15 shown, the transfer module 13 transfers the clamping and adjustment module 12 to the turntable module 14, the turntable module 14 rotates until the cone cover 124 and the core shaft are coaxial, the clamping and adjustment module 12 releases the noise reduction ring 21, and the assembly module 15 installs the noise reduction ring 21 on the belt sensor component 22.

[0037] That is, the noise reduction ring 21 installation equipment of the seat belt retractor realizes the automation of the installation of the noise reduction ring 21 through the mutual cooperation design between the storage and conveying module 11, the clamping and adjustment module 12, the transfer module 13, the assembly module 15 and the assembly module 15, thereby improving the overall production efficiency of the seat belt retractor; at the same time, the position and circumferential angle of the noise reduction ring 21 are monitored by the monitoring module, the circumferential angle of the noise reduction ring 21 is adjusted by the clamping and adjustment module 12, and the position of the noise reduction ring 21 is adjusted by other modules, especially the design corresponding to the cone cover 124 provided on the clamping and adjustment module 12 and the core shaft of the seat belt retractor, which ensures that the noise reduction ring 21 can be accurately installed on the belt sensor component 22; through the above two designs, the present equipment solves the problem of blindly installing the noise reduction ring 21 in the seat belt retractor in the prior art, because the noise reduction ring 21 is easily installed out of position due to the influence of the mutual cooperation and contact between the belt sensor component 22, the vehicle sensor component and the lock cover component 23 in the seat belt retractor, thereby affecting production efficiency and product quality.

[0038] In another embodiment, see Figure 1 and Figure 2 The storage and conveying module 11 includes a vibration disk component 111 and a direct vibration track component 112, and the noise reduction ring 21 is stored in the vibration disk component 111; the vibration disk component 111 is an automatic feeding device used to store and sort small parts such as the noise reduction ring 21 for subsequent installation processes; the working principle of the vibration disk component 111 can be briefly described as: through the internal vibration motor to generate periodic vibration, the disordered noise reduction rings 21 are gradually arranged in a neat direction in the hopper, and transported to the designated position through the track; its core principle is to use vibration and friction to make the parts move along the set trajectory in the hopper.

[0039] like Figure 1 and Figure 2 As shown, one end of the direct vibration track component 112 is connected to the vibration disk component 111; the other end is located below the clamping adjustment module 12 and is provided with an in-position detection sensor 113; the direct vibration track component 112 is used to smoothly and orderly transport the noise reduction ring 21 output by the vibration disk component 111 to the subsequent workstation 141, and baffles are provided on both sides to prevent the noise reduction ring 21 from moving sideways or tipping over; when the in-position detection sensor 113 detects that the noise reduction ring 21 is transmitted to the end of the direct vibration track component 112, the clamping adjustment module 12 grabs the noise reduction ring 21.

[0040] In another embodiment, see Figure 1The monitoring module includes a monitoring camera and a camera position adjustment component, which adjusts the pitch angle, circumferential angle and height position of the monitoring camera; thereby enabling the monitoring camera to monitor the position, posture and integrity of the parts in real time to ensure the accuracy and reliability of the production process. It is installed above the rotating disk; the monitoring camera identifies the position and direction of the noise reduction ring 21 through a preset template, extracts the outline of the noise reduction ring 21, determines whether it is complete or deformed, distinguishes different types of noise reduction rings 21, trains a neural network model, and realizes complex posture recognition or defect classification; the monitoring camera is triggered to shoot by sensors installed on other modules, and can shoot continuously, and effective images are filtered by software to reduce storage pressure; the detection results (such as position and direction) are transmitted to the control system for sorting or adjusting equipment parameters.

[0041] In another embodiment, see Figure 1 The clamping and adjusting module 12 includes the following components connected in sequence from bottom to top:

[0042] like Figure 3 There are two clamping arms 121 that are arranged opposite to each other, and the cone cover 124 is located between the two clamping arms 121.

[0043] like Figure 3 The first opening and closing cylinder 122 drives the two clamping arms 121 to close or separate.

[0044] like Figure 3 The rotating motor 123 drives the first opening and closing cylinder 122 to rotate, and drives the two clamping arms 121 to rotate.

[0045] The clamping and adjusting module 12 has a simple structure and works reliably.

[0047] like Figure 4 As shown, the lifting component 131 and the transverse moving component 132 can both be realized by using an electric telescopic cylinder to drive a slider to slide along a slide rail. This technology is mature and reliable.

[0048] In another embodiment, see Figure 1 and Figure 5 The turntable module 14 is provided with a plurality of workstations 141, and the frame and lock cover assembly 23 of the same seat belt retractor are located in the same workstation 141 and are arranged separately; the transfer module 13 transfers the clamping adjustment module 12 to the turntable module 14, and the turntable module 14 rotates to the core shaft of the seat belt retractor on the workstation 141 and is coaxial with the cone cover 124, and the clamping adjustment module 12 releases the noise reduction ring 21, and the assembly module 15 installs the noise reduction ring 21 on the belt sensing component 22; the moving module moves the clamping adjustment module 12 back to the direct vibration track component 112, re-grabs the noise reduction ring 21, and the turntable module 14 rotates, and the next workstation 141 rotates to the assembly position of the noise reduction ring 21, and the next work process starts, realizing the full automation of the installation of the noise reduction ring 21.

[0049] In other embodiments, Figure 1 and Figure 5 As shown, the assembly module 15 includes a lifting assembly part 151 and a clamping assembly part 152; the lifting assembly part 151 is installed on the turntable module 14 and drives the clamping assembly part 152 to move in the vertical direction; the clamping assembly part 152 includes two oppositely arranged semicircular clamping rings 1521 and a second opening and closing cylinder 1522 that drives the two clamping rings 1521 to be closed or separated; when the two clamping rings 1521 are closed, the noise reduction ring 21 lowered by the clamping adjustment module 12 is pressed onto the belt sensor component 22; the lifting assembly part 151 can be raised or lowered with the clamping assembly part 152 in time according to the rotation of the turntable module 14, so as to avoid interference between different components.

[0050] In summary, the present invention realizes the automation of the installation of the noise reduction ring 21 through the design of mutual cooperation between the storage and conveying module 11, the clamping and adjustment module 12, the transfer module 13, the assembly module 15 and the assembly module 15, thereby improving the overall production efficiency of the seat belt retractor; at the same time, the position and circumferential angle of the noise reduction ring 21 are monitored by the monitoring module, the circumferential angle of the noise reduction ring 21 is adjusted by the clamping and adjustment module 12, and the position of the noise reduction ring 21 is adjusted by other modules. In particular, the design of the cone cover 124 provided on the clamping and adjustment module 12 and the corresponding core shaft of the seat belt retractor ensures that the noise reduction ring 21 can be accurately installed on the belt sensor component 22, solving the problem that the noise reduction ring 21 is easily misplaced during installation, affecting production efficiency and product quality. Therefore, the present invention effectively overcomes the shortcomings of the prior art and has a high industrial utilization value.
