Description

[Correction by Rule 26.03.2019] Airbag manufacturing management system for vehicles

The present invention relates to a vehicle airbag manufacturing management system, and more specifically, in order to manufacture a vehicle airbag, displays a stacking order of parts in a process of stacking a plurality of parts, and detects a defect by detecting the thickness and color of the laminated parts. By discriminating and detecting in real time the supply amount of parts required for airbag manufacturing and the actual supply state of the sewing machine sewing the laminated parts, it is possible to suppress the occurrence of defects in the manufacturing process, increase productivity, and reduce manufacturing cost. It relates to a vehicle airbag manufacturing management system.

The airbag system for vehicles is a representative passenger protection device in addition to the seat belt. The airbag system consists of a detection system and an airbag module. The detection system consists of a sensor, battery, and diagnostic device, and the airbag module detects airbags and shocks. It consists of a system and an expansion device.

Therefore, when a vehicle body shock is detected by the sensor, the air bag module's expansion device explodes, and the explosive gas is injected into the air bag instantaneously, so that the air vehicle rapidly expands between the passenger's body and the main part inside the vehicle, causing the vehicle body shock to It is to protect passengers by absorbing and alleviating the direct transmission.

At this time, the airbag expands in a short time, usually about 50 / 1,000 seconds, by the explosive gas generated by the explosion of the expansion device, and is installed in a state folded in the main part of the vehicle along with the strength to withstand the explosion force of the expansion device. Then, rapid and accurate expansion and deployment performance is required by the explosive force of the expansion device.

Therefore, in order to provide the above-mentioned stiffness and accurate expansion and deployment performance, a normal airbag is a sewing type airbag in which fabrics of various thicknesses, colors, and materials (hereinafter referred to as `` parts '') with different characteristics for each part or function are joined or sewn. Mainly used.

However, in order to manufacture such a sewing type airbag, it is necessary to perform a sewing operation in a state in which a large number of parts are stacked in the correct position, and the number of laminated parts is different or stacked due to the operator's mistake by laminating parts manually by an operator. It is often the case that sewing is performed in a stacked state in a different order.

Particularly, the parts constituting the airbag have almost the same thickness, but most of the materials and shapes are slightly different, so that the worker performing the sewing operation stacks the parts in the wrong number or in the wrong order due to the illusion or mistake of the moment. It is often sewn.

As described above, if the number or order of laminated components constituting the airbag is changed, the airbag cannot be satisfied with rapid, accurate expansion and deployment performance, resulting in malfunction of the airbag.

This will be described with reference to FIGS. 1 to 2.

The vehicle airbag manufacturing management system of the present invention includes a supply module 10, an inspection module 20, a sewing module 30, and a control module 40.

The supply module 10 loads a plurality of components constituting an airbag, and includes a shelf unit 101, a display unit 102, and a sensor unit 103 to guide the discharge order of each component.

The shelf 101 is composed of a multi-stage parts loading table 101a in which a plurality of parts constituting an airbag are sorted and stacked by type.

The display unit 102 is installed on one side of each component loading table 101a to display the order of components to be discharged.

That is, the display unit 102 is provided with a display means such as a lamp to enable the operator to recognize the order of discharging the parts loaded on each of the parts loading table (101a).

Therefore, the lamp is lit according to the order in which the parts are discharged, so that the operator discharges the parts from the parts loading table 101a in which the lamps are lit, thereby preventing errors and mistakes in the order of discharging parts and enabling accurate discharge of parts. .

The sensor unit 103 is installed on one side of each component loading table 101a to detect a state in which parts are discharged from each component loading table 101a.

The control module 40 controls the operation of the display unit 102 in a pre-stored order.

That is, when a plurality of display units 102 are installed on the plurality of component loading racks 101a, the discharge order of the components loaded on each of the component loading racks 101a is pre-stored in the control module 40, thereby controlling the control module ( 40) as the control of the operation of the display unit 102 installed on each component loading base 101a, the display unit 102 is displayed in order.

In addition, when the display unit 102 is displayed, the sensor unit 103 detects the component discharge and provides the detection signal to the control module 40 as the worker discharges the component from the corresponding component loading table 101a. , The control module 40 determines the discharge state of the parts and controls the extinguishing of the corresponding display unit 102 and the lighting of the next display unit 102, thereby enabling the sequential display of the display unit 102.

3 is an exemplary view showing the configuration of an inspection module according to an embodiment of a vehicle airbag manufacturing management system of the present invention.

This will be described with reference to FIGS. 1 to 3.

The inspection module 20, the actuator 201, the thickness sensor in order to determine whether the lamination state is defective by sensing the thickness and color of parts stacked on the sewing table 301 of the sewing module 30 for sewing. 202.

The actuator 201 is installed on one side of the sewing head 302 of the sewing module 30, but it is desirable to use a pneumatic cylinder to vertically lift the piston rod, but it is not limited thereto.

The thickness sensor 202 is provided on the actuator 201 and is vertically installed on one side of the bracket installed at the lower end of the piston rod vertically elevating.

Therefore, when the stacked parts are loaded on the sewing table 301 for sewing, the thickness sensor 202 is lowered by the actuator 201 prior to sewing by the sewing module 30 to be stacked on the sewing table 301. The thickness of the parts stacked on the sewing table 301 is sensed by being in close contact with the top of the parts, and the sensing value is provided to the control module 40.

The thickness sensor 202 may be replaced with a non-contact type optical sensor.

That is, the optical sensor is installed on one side of the sewing module 30 to measure the thickness of the parts stacked on the sewing table 301 by emitting measurement light vertically downward, the reflection reflected on the surface of the stacked parts It is also possible to measure the thickness of the laminated parts through time measurement of light.

In the measurement of the thickness of the laminated parts using the optical sensor as described above, pressurizing means for vertically pressing the laminated parts to suppress the volume of parts made of fabric or the like so that the thickness of the laminated parts is accurately achieved. It may be further provided.

The pressing means is stacked in multiple layers by measuring the thickness using an optical sensor while using the actuator 201 or by installing a separate compressed air injection nozzle and pressing the laminated parts using compressed air injected at high pressure. The thickness of the part is accurately measured.

The inspection module 20 is characterized in that it further comprises a color sensor (203).

The color sensor 203 is installed on one side of the thickness sensor 202, detects the color of the parts stacked for sewing and provides the sensing value to the control module 40.

The color sensor 203 is preferably installed on one side of the bracket installed at the lower end of the piston rod of the actuator 201 for lifting of the thickness sensor 202 so that the color sensor 203 and the thickness sensor 202 can be elevated together. Do.

Therefore, when the parts stacked on the sewing table 301 for sewing are loaded, the color sensor 203 is also lowered by the actuator 201 prior to sewing, so that the upper part of the parts stacked on the sewing table 301 is spaced apart. In the spaced apart state, the color of the parts stacked on the sewing table 301 is detected, and the sensing value is provided to the control module 40.

On the other hand, it is revealed in advance that the inspection module 20 may further include a sensor for determining whether to attach various parts such as fixtures for installing the airbag inside the vehicle, as well as the thickness and color of the laminated parts.

The control module 40 compares at least one or more sensing values provided by the thickness sensor 202 and the color sensor 203 with a pre-stored reference value to determine whether or not the parts stacked for sewing are defective.

That is, the control module 40 pre-stores a thickness reference value in a predetermined range for the thickness of a component to be stacked for manufacturing an airbag, and a color reference value in a predetermined range for the color of the component.

Therefore, the control module 40 compares the sensing values provided by the thickness sensor 202 and the color sensor 203 with the pre-stored reference value, and determines that the sensing value is normal, and the sensing value is not included in the reference value. Otherwise, it is judged as defective.

Thus, the determination result according to whether the component is defective or not is output to the display 405 of the control module 40.

Therefore, when the normal judgment result is displayed on the display 405 of the control module 40, the worker proceeds to the sewing operation, and when the bad judgment result is displayed on the display 405, the worker is in a state of lamination or color of parts. By rechecking, it is prevented that the defective airbag is manufactured by sewing the parts as they are in a poorly stacked state.

This will be described with reference to FIGS. 1 to 4.

The sewing module 30, the sewing table 301, the sewing head 302, the upper thread detection sensor 303, the bobbin rotation detection sensor 305, for sewing the laminated parts for the airbag manufacturing to be integrally configured It includes a lower thread remaining amount detection sensor (306).

The sewing table 301 is placed on the upper portion of the sewing module 30 so that the components constituting the airbag are loaded and the sewing operation proceeds. At this time, the sewing table 301 can be rotated in place or moved in the X-axis or Y-axis direction.

The sewing head 302 is installed on the upper portion of the sewing table 301, a sewing needle module for performing a sewing operation is provided, and the sewing operation is performed by the sewing needle module.

That is, when the upper thread and the lower thread are supplied to the sewing needle module of the sewing head 302, the airbag component stacked on the sewing table 301 while the sewing needle module vertically elevates by the head driving unit provided in the sewing head 302. Weaving with the upper thread and the lower thread is performed.

The upper thread detection sensor 303 detects the supply state of the upper thread supplied to the sewing needle module for sewing and provides it to the control module 40.

That is, the upper thread detection sensor 303 is installed on the upper thread supply path on one side of the sewing head 302 to detect whether the upper thread is supplied, and provides the detection signal to the control module 40.

The bobbin rotation detection sensor 305 detects the supply state of the lower thread supplied to the sewing needle module for sewing and provides it to the control module 40.

That is, the bobbin rotation detection sensor 305 detects the rotational state of the bobbin 304 that is rotated under the sewing head 302 by winding a predetermined amount of the bobbin thread to supply the bobbin thread to the sewing needle module, thereby supplying the bobbin thread. The state is detected, and the detection signal is provided to the control module 40.

The lower thread is wound on the bobbin 304, and the bobbin 304 is rotatably installed under the sewing table 301, and as the bobbin 304 rotates, the bobbin 304 is wound and the sewing thread is released. It is supplied to the module.

Therefore, the bobbin rotation detection sensor 305 is installed on one side of the bobbin 304 that is rotatably installed under the sewing head 302 to detect the number of rotations of the bobbin 304, thereby detecting the supply state of the bobbin thread.

* In other words, a certain amount of the bobbin thread is wound on the bobbin 304 initially, and as the amount of the bobbin thread wound on the bobbin 304 gradually decreases as the sewing operation progresses, the circumferential speed of the bobbin 304 installed rotatably increases. Will increase.

In addition, when the bobbin 304 is unscrewed in the process of supplying the bobbin 304 to the sewing needle module, or when the bobbin thread is cut, the rotational speed of the bobbin 304 changes accordingly.

Therefore, when the bobbin rotation detection sensor 305 installed on one side of the bobbin 304 detects the number of revolutions of the bobbin 304 and provides the sensing value to the control module 40, the control module 40 pre-stores the bobbin ( The normal rotation speed reference value of 304) is compared with the rotation speed sensing value of the bobbin 304 provided by the bobbin rotation detection sensor 305 to determine whether the lower thread is normally supplied.

The remaining thread detection sensor 306 detects the remaining amount of the lower thread wound inside the bobbin 304 and provides it to the control module 40.

The lower thread remaining amount sensor 306 is preferably provided with a displacement sensor on one side of the bobbin 304 in order to detect the remaining amount of the lower thread wound inside the bobbin 304.

That is, the probe portion of the displacement sensor probes the winding portion of the bobbin 304 where the lower thread is wound, senses the remaining amount of the lower thread remaining in the winding portion, and then provides the sensing value (displacement value) to the control module 40.

Therefore, the control module 40 determines whether or not the bobbin 304 has a bobbin thread left by comparing the sensing value provided by the bobbin thread remaining amount sensor 306 with a reference value previously stored in the control module 40, and the determination result By displaying on the display 405, the sewing worker can check the remaining amount of the bobbin thread through the display 405 without having to check the bobbin 304 one by one.

The displacement sensor selectively selects any one of a contact type in which the probe part directly contacts the bobbin thread to sense the remaining amount of the bobbin thread, and a non-contact displacement sensor that senses the remaining amount of the bobbin thread without directly contacting the bobbin 304 through the optical method. Of course it can be used.

In addition, the contact displacement sensor is installed by using the actuator 201 to be able to elevate from the bottom of the bobbin 304, so that when the bobbin 304 is rotated, the probe unit descends so as not to contact the bobbin 304's lower thread, and then the bobbin ( When the rotation of 304) is stopped, the probe portion is raised to contact the bobbin 304 to check the remaining amount of the bobbin, thereby preventing the bobbin 304 from rotating from being cut by friction while contacting the probe. It becomes possible.
