Description

Technical Field

[0001] The utility model belongs to the technical field of safety airbags, and in particular relates to a checking tool capable of checking the outer contour of an airbag. Background Art

[0002] As people's consumption level improves, more and more people use cars as a means of transportation, and the potential safety hazards caused by traffic accidents are also increasing significantly. Equipping cars with airbags is an effective way to solve safety problems.

[0003] The working principle of an airbag is inflation, protection, and deflation. To complete the inflation task, the airbag must first be able to deploy smoothly. The folding size of the airbag is one of the factors that directly affects whether the airbag can be deployed smoothly. Therefore, the folding size of the airbag is also listed as a CC / SC characteristic (critical / important characteristic) by customers. For this type of size, customers usually achieve it by controlling the contour after folding.

[0004] However, existing conventional detection tools use template comparison detection, but template comparison detection is greatly affected by external factors, such as deviations caused by improper detection methods, or when the inspectors are visually fatigued, the inspectors are prone to misreading or missing inspections, resulting in abnormal products flowing to customers. Utility Model Content

[0005] The utility model provides a checking tool which can check the outer contour of an air bag and can effectively solve the above-mentioned problem.

[0008] As a further improvement, infrared sensing detectors are installed inside the upper contour receiving and detecting area and the lower contour receiving and detecting area, and the infrared sensing detectors are used to detect the folding contour position of the airbag.

[0009] As a further improvement, the bottom plate is provided with two groups of positioning holes at intervals on one side close to the positioning block, and the positioning holes are equipped with baffles.

[0010] As a further improvement, a barcode scanning area is also provided on the bottom plate, and the barcode scanning area is used to detect the position of the barcode after the airbag is folded.

[0011] As a further improvement, a controller is provided on a short side of the bottom plate away from the positioning block, and the controller is electrically connected to the infrared sensing detector and the barcode scanning area.

[0012] As a further improvement, the controller is provided with a main switch and a counter display screen, the main switch is used to control the switch control of the upper contour receiving detection area, the lower contour receiving detection area and the barcode scanning area, and the counter display screen is used to display the number of airbags scanned by the barcode scanning area and the scanning records of the airbags.

[0013] As a further improvement, the counter display screen is also equipped with a voice alarm.

[0014] The beneficial effects of the utility model are as follows: by setting a positioning block on the bottom plate to ensure that the initial folding position of the airbag detection is the same, and then by setting an upper contour receiving detection area and a lower contour receiving detection area on the bottom plate, an infrared sensing detector installed in the upper contour receiving detection area and the lower contour receiving detection area is used to detect the contour position of the airbag after folding, that is, through automatic detection, the problem of detection deviation or missed detection in manual detection is avoided.

[0022] The bottom plate 1 is a rectangular structure, and an upper contour receiving detection area 2 and a lower contour receiving detection area 3 are respectively arranged on the long sides of both sides of the bottom plate 1. A positioning block 5 is opened on one short side of the bottom plate 1, and the positioning block 5 is located between the upper contour receiving detection area 2 and the lower contour receiving detection area 3.

[0023] Furthermore, infrared sensing detectors are installed inside the upper contour receiving and detecting area 2 and the lower contour receiving and detecting area 3, and the infrared sensing detectors are used to detect the folding contour position of the airbag.

[0024] A positioning block 5 is set on the base plate 1 to ensure that the initial folding position of the airbag detection is the same, and then an upper contour receiving detection area 2 and a lower contour receiving detection area 3 are set on the base plate 1. An infrared sensing detector installed in the upper contour receiving detection area 2 and the lower contour receiving detection area 3 is used to detect the contour position of the airbag after folding. That is, automated detection is used to avoid detection deviations or missed detections in manual detection.

[0025] Furthermore, two groups of positioning holes 6 are arranged at intervals on one side of the bottom plate 1 close to the positioning block 5 , and the positioning holes 6 are equipped with baffles 7 .

[0026] By providing the baffle 7, it can be ensured that the airbag will not slip during the detection process, and it can also be ensured that the initial folding positions of the multiple groups of airbags will not change, thereby better ensuring the detection quality control of the airbag.

[0027] Furthermore, a barcode scanning area 4 is also provided on the bottom plate 1, and the barcode scanning area 4 is used to detect the position of the barcode after the airbag is folded.

[0028] By providing the barcode scanning area 4 , the number of detected airbags can be recorded through the barcode scanning area 4 , and the position of the airbag after folding can be detected through the barcode scanning area 4 to determine whether it meets the standard.

[0029] Furthermore, a controller 8 is provided on a short side of the bottom plate 1 away from the positioning block 5 , and the controller 8 is electrically connected to the infrared sensing detector and the barcode scanning area 4 .

[0030] Furthermore, the controller 8 is provided with a main switch 9 and a counter display screen 10, the main switch 9 is used to control the switch control of the upper contour receiving detection area 2, the lower contour receiving detection area 3 and the barcode scanning area 4, and the counter display screen 10 is used to display the number of airbags scanned by the barcode scanning area 4 and the scanning records of the airbags.
