Description

Technical Field

[0001] The utility model relates to the technical field of seat belt buckle and lock pin assembly, in particular to a seat belt buckle and lock pin assembly device based on extrusion deformation and wear prevention. Background Art

[0002] In the existing seat belt manufacturing field, assembling the seat belt lock pin to the seat belt buckle is a crucial step. However, there are significant problems with traditional assembly techniques in this step. Specifically, when the lock pin attempts to cooperate with the seat belt buckle to be assembled, the seat belt buckle often pre-laps on the sliding table, resulting in the seat belt lock pin directly abutting against the outside of the seat belt buckle during assembly. This interference not only increases the assembly difficulty and reduces production efficiency, but more importantly, it often causes the lock pin to jam during assembly and unable to complete the assembly smoothly.

[0003] The seat belt buckle and the seat belt lock pin are prone to jamming during the assembly process. The main reason is that the clearance between the lock pin and the buckle is too small, or the shape and size of the lock pin do not match the buckle, resulting in excessive friction or resistance during the assembly process. This may not only damage the surfaces of the lock pin and the buckle, affecting the appearance quality of the product, but also may damage the overall structure of the product, reducing its service performance and safety.

[0004] The assembly mechanism for an automobile seat belt buckle assembly device with the Chinese patent authorization announcement number CN210731557U includes a frame, a first buckle structure for placing the first buckle mounted on the frame, a second buckle structure for placing the second buckle piece, a first driving and locking structure, and a positioning structure; the first buckle structure includes a first placing plate, and the first placing plate is provided with a through hole; the second buckle structure includes a hollow first limiting frame and a first lifting plate located inside the first limiting frame, one end of the first limiting frame passes through the through hole, and one end of the first lifting plate is used for placing the second buckle piece; the first driving and locking structure includes a first driving member for driving the first lifting plate to approach and / or move away from the first placing plate, a first connecting plate, a second connecting plate, and a second driving member. The above-mentioned prior art can improve the assembly stability of the product, and the product qualification rate is high.

[0005] However, in actual use of the above structure, when assembling the seat belt buckle and the seat belt lock pin, there is a lack of a pre-inclination mechanism for the seat belt buckle, resulting in the seat belt lock pin being easily in direct contact with the seat belt buckle to be assembled and jamming when pushed by the driving mechanism, reducing the assembly efficiency.

Detailed implementation manners

[0029] In order to further understand the features, technical means, specific purposes and functions achieved by the present utility model, the present utility model will be described in further detail below in conjunction with the drawings and specific implementation manners.

[0030] Refer to Figures 1-5 As shown, the seat belt buckle and lock pin assembly device based on extrusion deformation and anti-wear includes a housing 1, a receiving table 2 arranged beside the housing 1, and a sliding table 3 slidably arranged on the top of the receiving table 2 and used to hold the seat belt buckle and lock pin to be assembled. The seat belt buckle and lock pin assembly device further includes an assembling mechanism 4 and an intermittent feeding mechanism 5; the assembling mechanism 4 is arranged beside the housing 1, and the assembling mechanism 4 includes a sliding part 41, a pushing part 42, a rotating contact plate 43 and a contacting part 44; the sliding part 41 is slidably arranged on the top of the housing 1 and beside the sliding table 3, and the sliding part 41 is used to push the seat belt lock pin to be assembled; the pushing part 42 is arranged outside the sliding part 41 and beside the sliding table 3; the rotating contact plate 43 is rotatably arranged on one side of the housing 1 and above the sliding table 3, and the rotating contact plate 43 is used to abut the seat belt buckle to be assembled and make the seat belt buckle to be installed in an inclined state; the contacting part 44 is arranged on one side of the pushing part 42, and the contacting part 44 is in a semi-circular shape; the intermittent feeding mechanism 5 is arranged on the top of the housing 1 and beside the sliding part 41.

[0031] A compression spring is provided on the top of the sliding table 3. The compression spring is used to abut the to-be-assembled seat belt buckle and the to-be-assembled seat belt lock pin against each other. For details, please refer to the attached Figure 4 . In the initial state, the to-be-assembled seat belt buckle is abutted against the top of the sliding table 3. When the sliding part 41 drives the contact part 44 to move, in order to prevent interference between the to-be-assembled lock pin and the abutted to-be-assembled seat belt buckle. The sliding part 41, the pushing part 42 and the contact part 44 move synchronously on the top of the housing 1. When the sliding part 41 moves, the to-be-assembled seat belt lock pin on the top of the housing 1 can be pushed. Since the pushing part 42 and the contact part 44 can contact the to-be-assembled plug pin and the rotating contact plate 43 first, when the contact part 44 contacts the rotating contact plate 43, the rotating contact plate 43 can be lifted first. When the rotating contact plate 43 is in an inclined state, it can abut against the to-be-assembled seat belt buckle and drive the to-be-assembled seat belt buckle to be in a squeezed inclined state. And the rotating contact plate 43 is preferably made of alloy material, which can reduce the contact damage to the to-be-assembled seat belt lock pin. Ensure that the to-be-assembled plug pin can be located below the to-be-assembled seat belt buckle, effectively preventing the phenomenon of jamming that is likely to occur when assembling the seat belt buckle and the seat belt lock pin, thereby improving the assembly efficiency and reliability.

[0032] See Figures 3-5 As shown, the assembly mechanism 4 further includes a telescopic cylinder 45; the telescopic cylinder 45 is provided on the top of the housing 1 and above the sliding table 3, and the sliding part 41 is connected to the output end of the telescopic cylinder 45.

[0033] When the telescopic cylinder 45 is started, it can drive the sliding part 41, the pushing part 42 and the contact part 44 to move synchronously. When the sliding part 41 moves, the to-be-assembled seat belt lock pin on the top of the housing 1 can be pushed. So that when the contact part 44 contacts the rotating contact plate 43, the rotating contact plate 43 can be lifted first.

[0034] See Figures 3-6 As shown, the assembly mechanism 4 further includes a first telescopic spring 46; the first telescopic spring 46 is provided on the top of the housing 1. One end of the first telescopic spring 46 is fixedly connected to the housing 1, and the other end of the first telescopic spring 46 is fixedly connected to the rotating contact plate 43.

[0035] When the contact part 44 abuts against the rotating contact plate 43 and makes it in an inclined state, the first telescopic spring 46 is immediately in a compressed state. Subsequently, after the seat belt buckle and the seat belt lock pin are assembled, and the pushing part 42 and the contact part 44 have moved away from the sliding table 3, the contact part 44 will contact the rotating contact plate 43 again, thereby driving the rotating contact plate 43 to return to the inclined state. This process continues until the contact part 44 no longer abuts against the rotating contact plate 43. After that, the rotating contact plate 43 will return to its initial position by the thrust of the first telescopic spring 46.

[0036] See Figure 7 and Figure 8 As shown, the intermittent feeding mechanism 5 includes a feeding rack 51, mounting blocks 52, a rotation limiting plate 53 and a limiting plate 54; the feeding rack 51 is arranged on the top of the machine housing 1 and beside the telescopic cylinder 45; there are a pair of mounting blocks 52 which are respectively arranged on the top of the feeding rack 51; the rotation limiting plate 53 is rotatably arranged on the top of the mounting block 52 and above the feeding rack 51; the limiting plate 54 is arranged at the bottom of the rotation limiting plate 53, and the limiting plate 54 is used to keep the safety belt lock pins to be assembled in a separated state.

[0037] The safety belt lock pins to be assembled can be placed on the top of the feeding rack 51 by means of a robotic arm. The inclination of the feeding rack 51 ensures that the safety belt lock pins to be assembled can roll stably until they reach below the rotation limiting plate 53. The limiting plate 54 is used to effectively separate the next safety belt lock pin to be assembled, preventing multiple lock pins from passing through the rotation limiting plate 53 simultaneously and staying below the sliding part 41.

[0038] See Figure 8 and Figure 9 As shown, the intermittent feeding mechanism 5 further includes a contact ball 55, a connecting part 56, a flipping part 57 and an abutting part 58; the contact ball 55 is arranged at the bottom of the rotation limiting plate 53; the connecting part 56 is arranged on one side of the sliding part 41 and beside the feeding rack 51; the flipping part 57 is rotatably arranged at the bottom of the connecting part 56; the abutting part 58 is arranged on one side of the flipping part 57, and when the abutting part 58 contacts the contact ball 55, it can drive the abutting part 58 and the flipping part 57 to be in a flipped state.

[0039] When the telescopic cylinder 45 is activated and drives the sliding part 41 to move, it can drive the connecting part 56 to move synchronously during this process. When the connecting part 56 moves, it can drive the flipping part 57 and the abutting part 58 to move until the abutting part 58 contacts the contact ball 55. When contacting, it can turn the contact ball 55 and the rotation limiting plate 53 into a rising and flipped state. At this time, the limiting plate 54 loses the limitation on the safety belt lock pins to be assembled, enabling the safety belt lock pins to be assembled to roll below the sliding part 41, facilitating the next assembly work.

[0040] See Figures 7-9 As shown, the intermittent feeding mechanism 5 further includes a second telescopic spring 59; the second telescopic spring 59 is arranged on the top of the feeding rack 51, and one end of the second telescopic spring 59 is fixedly connected to the feeding rack 51, and the other end of the second telescopic spring 59 is fixedly connected to the rotation limiting plate 53.

[0041] When the abutting portion 58 contacts the contact ball 55 and drives the rotation limiting plate 53 to be in an upward inclined state, the second telescopic spring 59 is in a compressed state. It is ensured that when the rotation limiting plate 53 is in an upward inclination, the second telescopic spring 59 is in a compressed state, and when the abutting portion 58 no longer contacts the contact ball 55, the second telescopic spring 59 releases the energy it stores and pushes the rotation limiting plate 53 back to its initial position. This process enables the rotation limiting plate 53 and the limit plate 54 to quickly separate the next seat belt lock pin to be assembled, thus realizing the intermittent feeding function of the seat belt lock pins to be assembled.

[0042] See Figures 7-10 As shown, the intermittent feeding mechanism 5 further includes a limiting piece 591 and an abutting block 592; the limiting piece 591 is arranged at the top of the flipping portion 57 and there are a pair of them; the abutting block 592 is arranged at the bottom of the connecting portion 56 and beside the flipping portion 57, and when the flipping portion 57 flips, it can drive the limiting piece 591 to be in an abutting state with the abutting block 592 and stop flipping.

[0043] After the abutting portion 58 contacts the contact ball 55, it can trigger the contact ball 55 and the rotation limiting plate 53 to enter an upward flipping state. This process continues until the flipping portion 57 and the limiting piece 591 contact the abutting block 592. At this time, the flipping action stops, the flipping portion 57 reaches a fixed flipping angle, and the contact ball 55 is pushed up, thereby causing the rotation limiting plate 53 to flip, ensuring that a seat belt lock pin to be assembled can pass stably. When the sliding portion 41 moves in a direction away from the sliding table 3, the contact portion 44 will contact the contact ball 55 arranged at the bottom of the rotation limiting plate 53 again. At this time, the flipping portion 57 presents a reverse rotation state away from the abutting block 592 and is no longer restricted by the abutting block 592, so it can continue to flip. The flipping process continues until the flipping portion 57 no longer contacts the contact ball 55 and does not push up the contact ball 55 and the rotation limiting plate 53, thus realizing the intermittent sequential feeding function of the seat belt lock pins to be assembled and ensuring the effect that only one seat belt lock pin to be assembled can pass each time.

[0044] See Figure 9 and Figure 10 As shown, a flipping groove for the flipping portion 57 to flip is provided at the top of the connecting portion 56.

[0045] When the flipping portion 57 flips in the reverse direction, it can flip stably through the flipping groove.

[0046] Working principle: An extrusion spring is provided on the top of the sliding table 3, and the extrusion spring is used to abut the to-be-assembled seat belt buckle and the to-be-assembled seat belt lock pin against each other. When the sliding part 41 drives the contact part 44 to move, the sliding part 41, the pushing part 42 and the contact part 44 move synchronously on the top of the casing 1 to push the to-be-assembled seat belt lock pin on the top of the casing 1, and at the same time prevent interference with the to-be-assembled buckle. The pushing part 42 and the contact part 44 first contact the rotating contact plate 43 and lift it to an inclined state, and then abut against the to-be-assembled seat belt buckle and make it in an inclined state, ensuring that the to-be-assembled plug can be smoothly located below the buckle, effectively preventing jamming phenomena, and improving the assembly efficiency and reliability. When the contact part 44 abuts against the rotating contact plate 43 and makes it inclined, the first telescopic spring 46 is compressed. After the assembly is completed, when the pushing part 42 and the contact part 44 move away from the sliding table 3, the contact part 44 contacts the rotating contact plate 43 again, driving the rotating contact plate 43 to return to the inclined state until it no longer abuts. Thereafter, the rotating contact plate 43 returns to its initial position under the thrust of the first telescopic spring 46. The to-be-assembled seat belt lock pin is placed on the top of the feeding rack 51 by a robotic arm, and the inclination of the feeding rack 51 ensures that the lock pin rolls stably under the rotating limiting plate 53. The limiting plate 54 separates the next lock pin to prevent multiple lock pins from passing through the rotating limiting plate 53 at the same time. When the telescopic cylinder 45 is activated to drive the sliding part 41 to move, the connecting part 56, the flipping part 57 and the abutting part 58 move synchronously until the abutting part 58 contacts the contact ball 55, making the contact ball 55 and the rotating limiting plate 53 in a rising and flipping state, and the limiting plate 54 loses its limiting function, and the lock pin rolls under the sliding part 41 for the next assembly. When the abutting part 58 contacts the contact ball 55 and drives the rotating limiting plate 53 to be inclined, the second telescopic spring 59 is compressed. When the abutting part 58 no longer contacts, the second telescopic spring 59 releases energy and pushes the rotating limiting plate 53 back to its initial position, realizing the intermittent feeding function of the lock pin. During this process, when the flipping part 57 and the limiting piece 591 contact the abutting block 592, the flipping action stops, reaching a fixed flipping angle to ensure that one lock pin passes stably. When the sliding part 41 moves away from the sliding table 3, the contact part 44 contacts the contact ball 55 again, and the flipping part 57 rotates in the reverse direction and is no longer restricted until it no longer contacts and does not lift the contact ball 55 and the rotating limiting plate 53, realizing the intermittent sequential feeding function of the lock pin to ensure that only one lock pin passes each time.
