Description

Technical Field

[0001] This utility model relates to the field of seal technology, specifically to a seal error prevention device. Background Technology

[0002] Currently, during the production of automotive airbags, a stamp is used to mark the surface of the airbag. This is usually to identify relevant information about the airbag, such as the manufacturer, production date, batch number, or specific safety certification marks.

[0003] Because multiple different stamps are often needed on the surface of the airbag, in order to ensure the uniformity of the stamps, the stamps are usually placed on a stamp holder and the airbag is placed at the bottom for stamping. However, because there are many stamps and they are similar in shape, it is easy to place them incorrectly during the placement process, resulting in stamping errors. Utility Model Content

[0004] This utility model proposes a seal error prevention device, which solves the problems in related technologies where seals are easily used incorrectly and cannot be distinguished from one another.

[0005] The technical solution of this utility model is as follows:

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stamp error prevention device, including a base, the top of the base is provided with a limiting seat, the limiting seat is provided with a plurality of limiting grooves, the top of the base is welded with a positioning fixture, the positioning fixture is provided with a plurality of positioning grooves, the positioning grooves correspond to the limiting grooves, the positioning grooves are provided with a positioning block inside, and the positioning block is provided with a magnet inside.

[0007] It also includes an outer shell, the inside of which is provided with a square groove, and the inside of which is slidably connected to the stamp body. A connecting post is welded to the stamp body, and a pressure block is welded to the top of the connecting post. A fixing block is welded to the inner wall of the square groove, and two parallel reset springs are welded together between the fixing block and the pressure block.

[0008] The outer shell is provided with a limiting block, the limiting block has a straight groove inside, a slider is slidably connected inside the straight groove, a limiting spring is welded between the slider and the straight groove, the slider has a sliding groove inside, a locking block is slidably connected inside the sliding groove, and the stamp body has a locking slot inside, the shape and size of the locking slot and the locking block are matched.

[0009] Preferably, the top of the limiting block is provided with a protrusion, and the outer shell is provided with a limiting groove that matches the protrusion.

[0010] Preferably, the slider has an internal suction block made of metal, which is used to move the slider downwards to release the seal body from its constraints.

[0011] Preferably, the outer shell has a positioning groove, and the shape and size of the positioning groove match those of the limiting block.

[0012] Preferably, both sides of the base are fixedly connected with handles by screws.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] 1. This utility model sets sliders and matching magnets at different positions on different stamps. After the correct stamp is placed on the correct positioning block, the magnet will attract the slider, causing the block to detach from the stamp body and remove its restriction. Only then can the stamp be pressed to stamp, ensuring that the stamp is the correct one every time, thus guaranteeing the quality of the airbag product.

[0015] 2. This utility model allows personnel to easily distinguish and arrange different stamps by setting raised blocks at different positions on different stamps. Attached Figure Description

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] like Figures 1-5 As shown, this embodiment proposes a stamp error prevention device, including a base 1, a limiting seat 3 is provided on the top of the base 1, the limiting seat 3 is provided with a plurality of limiting grooves 4, a positioning fixture 5 is welded on the top of the base 1, the positioning fixture 5 is provided with a plurality of positioning grooves 6, the positioning grooves 6 and the limiting grooves 4 are corresponding, a positioning block 7 is provided inside the positioning groove 6, and a magnet 8 is provided inside the positioning block 7.

[0025] It also includes a housing 10, with a square groove inside the housing 10. A stamp body 11 is slidably connected inside the square groove. A connecting post is welded to the stamp body 11. A pressure block 9 is welded to the top of the connecting post. A fixing block 12 is welded to the inner wall of the square groove. Two parallel reset springs 13 are welded together between the fixing block 12 and the pressure block 9.

[0026] The outer casing 10 is provided with a limiting block 15. The limiting block 15 has a straight groove inside. A slider 16 is slidably connected inside the straight groove. A limiting spring 18 is welded between the slider 16 and the straight groove. The slider 16 has a sliding groove 19 inside. A locking block 17 is slidably connected inside the sliding groove 19. The stamp body 11 has a locking slot 14 inside. The shape and size of the locking slot 14 and the locking block 17 are matched.

[0027] like Figures 1-5 As shown, the top of the limiting block 15 is provided with a protrusion 20, and the upper part of the outer shell 10 is provided with a limiting groove 4 that matches the protrusion 20.

[0028] like Figures 1-5 As shown, the slider 16 has an attraction block inside. The attraction block is made of metal and is used to move the slider 16 downward to release the restriction of the stamp body 11. The outer shell 10 has a positioning groove 6. The positioning groove 6 and the limiting block 15 are matched in shape and size. Both sides of the base 1 are fixedly connected to the handle 2 by screws.

[0029] In this embodiment, by setting matching magnets 8 and attraction blocks inside different stamps and limiting blocks 15, when stamping the surface of the airbag sheet, the airbag sheet is first placed between the limiting seat 3 and the positioning fixture 5 and the stamp is placed inside the positioning groove 6. The limiting block 15 is placed in the positioning groove 6. If the positions of the magnet 8 and the attraction block match at this time, the attraction block will drive the slider 16 to move downward under the attraction of the magnet 8. During the downward movement of the slider 16, the locking block 17 connected therein will move along the direction of the slide groove 19, that is, move to the right until it is completely moved out of the locking slot 14 inside the slide groove 19, and finally release the limitation on the stamp body 11. At this time, the pressing block 9 can be pressed down. The pressing block 9 will drive the stamp body 11 to move downward to stamp the upper surface of the airbag sheet located at the bottom.

[0030] When the positions of magnet 8 and attraction block are mismatched, the card block 17 is still inside the card slot 14, which serves to limit the stamp body 11. At this time, the stamp body 11 cannot be pressed down to prevent the stamp from being stamped incorrectly. In addition, personnel can also distinguish each stamp according to the different positions of the protrusion 20.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
