[0035] Figure 1 The three-dimensional structure of the bolt and gasket press-fitting device of the airbag is shown. Figures 3 to 5 The three-dimensional structure of the bearing mechanism of the bolt and gasket press-fitting device is shown; in order to clearly illustrate the structure of the bearing mechanism, Figure 3 、 Figure 4 、 Figure 5 Some parts of the supporting mechanism are hidden in the figure. Figure 1 、 Figures 3 to 5 As shown, the bolt gasket press-fitting device for the airbag provided by the embodiment of the utility model includes:

[0036] The carrier mechanism 10 includes a carrier assembly 11, a clamping assembly 12, a feed assembly 13, and a sensor assembly. The carrier assembly 11 includes an airbag carrier platform 111, a gasket receiving groove 112 provided on the airbag carrier platform 111, and a feed trough 113 connected to the gasket receiving groove 112. The clamping assembly 12 can move relative to the airbag carrier platform 111, and the feed assembly 13 can move along the feed trough 113. The detection range of the sensor assembly covers the carrier assembly 11 and / or the clamping assembly 12 and / or the feed assembly 13.

[0037] The driving mechanism 20 includes a driving assembly 21 and a bolt pressing head 22 connected to the driving assembly 21 . The driving assembly 21 can drive the bolt pressing head 22 to press into and out of the gasket receiving groove 112 .

[0038] The airbag carrier 111 is used to place the airbag, and the clamping assembly 12 moves relative to the airbag carrier 111 to clamp the airbag placed on the airbag carrier 111, ensuring that the airbag is accurately positioned. The gasket 61 is placed in the gasket receiving groove 112 provided on the airbag carrier 111, so that the gasket 61 is accurately aligned with a specific part of the airbag. The feed trough 113 is connected to the gasket receiving groove 112, and the feeding assembly 13 moves along the feed trough 113 to accurately convey the gasket 61 to the gasket receiving groove 112; by controlling the height of the feed trough 113, it can be ensured that one gasket 61 is conveyed to the gasket receiving groove 112 at a time to avoid overloading. The sensor assembly is used to detect whether the carrier assembly 11 / clamping assembly 12 / feeding assembly 13, etc. are in place, to ensure that the airbag / gasket 61, etc. are in place and accurately aligned, to avoid missing installation and deviation. The bolt press 22 carries the bolt 62, and the driving component 21 drives the bolt press 22 to press into the gasket receiving groove 112, pressing the bolt 62 and the gasket 61 to a specific position of the airbag to achieve accurate press-fitting; then, the driving component 21 drives the bolt press 22 to withdraw from the gasket receiving groove 112, and the press-fitting is completed.

[0039] in, Figure 4 The diagram shows the state of the bolt 62 after press-fitting is completed.

[0040] Therefore, the bolt and gasket press-fitting device for the airbag of the utility model can effectively avoid over-installation or missing installation of the gasket 61, and can achieve accurate alignment between the airbag, the bolt 62, and the gasket 61, thereby achieving accurate press-fitting and improving product yield and processing efficiency.

[0041] In some embodiments, a seat ring pin accommodating hole 114 is provided on the airbag supporting platform 111 , and the clamping assembly 12 includes a clamping claw 121 that cooperates with the seat ring pin accommodating hole 114 .

[0042] The seat pin receiving hole 114 is for receiving the seat pin of the airbag (i.e., the pin provided on the airbag bag), so that the airbag is accurately positioned on the airbag support platform 111. The clamping assembly 12 includes a clamping jaw cylinder 122, whose clamping jaw 121 cooperates with the seat pin receiving hole 114 to clamp and lock the seat pin placed in the seat pin receiving hole 114, thereby stably positioning the airbag on the airbag support platform 111, so that the airbag, gasket 61, and bolt 62 are aligned and press-fitted.

[0043] In some embodiments, the sensing assembly includes a photoelectric sensor 141 whose detection range covers the seat pin receiving hole 114. The photoelectric sensor 141 can be a reference type photoelectric sensor, which is installed on the opposite side of the airbag support platform 111 and is used to detect whether the airbag seat pin is accurately placed in the seat pin receiving hole 114. If so, the clamping cylinder 122 is driven by a PLC (Programmable Logic Controller) to clamp the seat pin.

[0044] In some embodiments, the airbag support platform 111 is further provided with a plurality of movable pressing members 116, which can cover and avoid the edges of the gasket receiving groove 112. When the movable pressing members 116 cover the edges of the gasket receiving groove 112, they can press the gasket 61 and prevent it from falling out of the gasket receiving groove 112; when the movable pressing members 116 avoid the edges of the gasket receiving groove 112, the press-fitted gasket 61 can be removed.

[0045] The movable pressing member 116 can realize the switching between the pressing state and the avoiding state by a spring, or can realize the switching between the pressing state and the avoiding state by a driving member such as a cylinder.

[0046] In some embodiments, the movable pressing member 116 includes a spring 116a and a pressing block 116b connected to the spring 116a. The spring 116a is used to drive the pressing block 116b to press against the edge of the gasket receiving groove 112. The spring 116a can be a torsion spring. In its natural state, the spring 116a drives the pressing block 116b to press against the edge of the gasket receiving groove 112. When the press-fitted gasket 61 (including the bolt 62 and the airbag) is removed, the gasket 61 pushes the pressing block 116b, which rotates to make way for the gasket 61 to exit.

[0047] In some embodiments, the airbag support platform 111 includes a support block 111a and a cover plate 111b stacked on the support block 111a. The gasket accommodating groove 112 and the feed trough 113 are set on the support block 111a. The cover plate 111b exposes the gasket accommodating groove 112 and limits the height of the feed trough 113.

[0048] Cover plate 111b exposes gasket accommodating groove 112, facilitating the insertion of bolt 62 and the removal of gasket 61 after press-fitting. The height of feed trough 113 can be equal to or slightly greater than the thickness of gasket 61, ensuring that only one gasket 61 is delivered to gasket accommodating groove 112 at a time, thus preventing overloading of gaskets 61. Cover plate 111b also exposes seat ring pin accommodating hole 114, facilitating the insertion and removal of the airbag seat ring pin.

[0049] The side walls of the airbag support platform 111 may further be provided with some blocks 117 for limiting the position of the airbag and playing a limiting role for the airbag.

[0050] In some embodiments, the sensing assembly includes a fiber optic sensing assembly, and the detection range of the fiber optic sensing assembly covers the gasket receiving groove 112. The fiber optic sensing assembly may specifically include a fiber optic amplifier 142 and a fiber optic sensor 143. The fiber optic amplifier 142 and the fiber optic sensor 143 cooperate to detect the presence of the gasket 61 in the gasket receiving groove 112. Press-fitting is performed only when the gasket 61 is present to avoid missing the gasket 61.

[0051] In some embodiments, the feed assembly 13 includes a push rod 131 that can extend into the feed trough 113 and a guide rail assembly 132 connected to the push rod 131. The guide rail assembly 132 slides in a direction parallel to the extension direction of the feed trough 113. The guide rail assembly 132 includes a guide rail 132a and a slider 132b. The push rod 131 is connected to the slider 132b to achieve the pushing motion.

[0052] According to the spatial positions between the components, components such as a connecting block 133 may be provided to achieve the connection between the push rod 131 and the slider 132b.

[0053] In some embodiments, the feeding assembly 13 further includes a handle 134 connected to the pushing rod 131 and a limiting mechanism 135 cooperating with the guide rail assembly 132 , wherein the limiting mechanism 135 is used to limit the position of the slider 132 b of the guide rail assembly 132 .

[0054] The push rod 131 can be manipulated by the handle 134 to push the gasket 61. The position of the slider 132b is limited by the limiting mechanism 135 to keep the position of the push rod 131 stable so that the gasket 61 is fixed during press-fitting.

[0055] In some embodiments, the limiting mechanism 135 includes an upper position magnetic portion 135a and an advance position magnetic portion 135b arranged on one side of the guide rail 132a of the guide rail assembly 132, and a magnetic member 135c connected to the slider 132b of the guide rail assembly 132.

[0056] When the magnetic element 135c moves to the upper material position magnetic portion 135a, the push rod 131 exits the feed trough 113, and the gasket 61 can be placed in the feed trough 113 at this time; when the magnetic element 135c moves to the advancing position magnetic portion 135b, the push rod 131 pushes the gasket 61 in the feed trough 113 to the gasket accommodating groove 112.

[0057] The loading magnetic portion 135a and the pushing magnetic portion 135b have an adsorption effect on the magnetic element 135c, so that the magnetic element 135c remains stationary when it moves to the loading magnetic portion 135a and the pushing magnetic portion 135b, thereby keeping the push rod 131 stable at the corresponding position.

[0058] In some embodiments, the sensor assembly includes proximity sensors 144, which are respectively disposed on the loading position magnetic attraction portion 135a and the pushing position magnetic attraction portion 135b. The proximity sensors 144 detect the position of the feeding assembly 13 to control the loading and pressing processes.

[0059] Furthermore, Figure 2 The three-dimensional structure of the bolt gasket press-fitting device is shown in figure. Figure 1 and Figure 2 As shown, in some embodiments, a magnet is provided in the bolt pressing head 22 to magnetically attract the bolt 62. The end of the bolt pressing head 22 can be formed into a hollow structure so that the bolt 62 is partially embedded in the bolt pressing head 22, thereby preventing the bolt 62 from being displaced due to force during the initial stage of press-fitting.

[0060] In some embodiments, the drive assembly 21 includes a cylinder 211, which is connected to an electrostatic sensor 212. When the electrostatic sensor 212 is activated, the cylinder 211 is depressurized. If the cylinder 211 is not fully activated, the on / off switch of the electrostatic sensor 212 can be pressed to depressurize the cylinder 211. At this point, the piston rod 211a of the cylinder 211 can be manually moved to accurately align the bolt 62 with the gasket 61. After manually aligning the bolt 62 with the gasket 61, the on / off switch of the electrostatic sensor 212 can be pressed again, and the cylinder 211 can continue the press-fitting process, achieving accurate press-fitting.

[0061] In some embodiments, the piston rod 211a of the cylinder 211 is connected to the bolt pressing head 22, and the piston rod 211a is also connected to the adjustment handle 211b. The adjustment handle 211b can be formed in the shape of a rotating ball to facilitate manual operation of the piston rod 211a, and the auxiliary bolt 62 is positioned concentrically with the gasket 61.

[0062] In some embodiments, the driving mechanism 20 also includes a buffer limit assembly, which includes a buffer head 232 installed on the movable rod 231 and a limit block 233 installed on the mounting plate 31; wherein, the driving assembly 21 is installed on the mounting plate 31, and the movable rod 231 moves with the driving assembly 21.

[0063] Movable rod 231 is connected to piston rod 211a and can move along lifting rail 213. The buffering and limiting action of buffer head 232 and stop block 233 limits the downward position of cylinder 211, preventing overpressure. Furthermore, the upward position of cylinder 211 can be limited by stop seat 214, ensuring a stable stroke of cylinder 211.

[0064] In some embodiments, the driving mechanism 20 is further provided with any of the following components: a speed regulating joint 215, used to adjust the exhaust speed of the cylinder 211; a one-way check valve 216, used to prevent the cylinder 211 from falling to the bottom after a long period of non-operation under the action of gravity; a position detection sensor 217, which can be a proximity sensor, used to detect the position of the feedback cylinder 211 together with the induction plate 218; an indicator light 24, which lights up to confirm that the bolt and gasket pressing conditions are met.

[0065] Continue to combine Figure 1 and Figure 2 As shown, in some embodiments, the supporting mechanism 10 is mounted on a base 30 , and the driving mechanism 20 is mounted on the base 30 via a support base 32 ; a mounting rail 33 and a knob plunger 34 are also provided on the back of the base 30 .

[0066] The support base 32 is used to provide space for installing the drive mechanism 20. A sensor distributor 145 may also be provided on the support base 32 to enable communication between the sensors.

[0067] The slide rails 33 are installed for the base 30 to slide on the workbench. After the base 30 is positioned, the base 30 can be fixed to the workbench by the knob plunger 34. According to the layout requirements, components such as the connecting seat 35 and the reinforcing plate 36 can also be provided to achieve a stable arrangement of the carrying mechanism 10 and the driving mechanism 20.

[0068] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
