Description

Technical Field

[0001] The utility model relates to the field of detection equipment, and particularly relates to a vehicle airbag size detection device. Background Art

[0002] With the rapid development of advanced manufacturing technology in China and the reduction of automobile manufacturing costs, automobiles have been widely popularized in people's daily lives, bringing great convenience to people's daily travel. As an important part of an automobile, the production quality of an airbag is of great concern to the driving safety of users. If the size of the airbag exceeds the range, it will affect the normal ejection of the airbag in an emergency. The traditional measurement of the airbag seal size is carried out manually using measuring tools such as vernier calipers, which has the disadvantages of inaccurate detection and low efficiency.

[0003] Therefore, the prior art provides a device for detecting an airbag, including a frame, a transparent flat plate, a plurality of detection cameras, a driving device and an adsorption device. The transparent flat plate and the detection cameras are installed on the frame, and the detection cameras are located above the transparent flat plate. The driving device includes a horizontal sliding mechanism and a lifting cylinder. The horizontal sliding mechanism is installed on the frame, the lifting cylinder is hoisted below the horizontal sliding mechanism, and the cylinder shaft of the lifting cylinder is fixedly connected to the adsorption device. When the device is used, the driving device and the adsorption device cooperate to suck up the airbag to be detected, move it and lay it flat on the transparent flat plate. Then, the driving device drives the adsorption device back to the original position, and the detection cameras photograph the airbag to be detected to determine whether the airbag is qualified. After detection, the driving device and the adsorption device cooperate to suck up the measured airbag on the transparent flat plate, move it to the good product turnover cart or the defective product turnover cart according to the determination result, and then put down the airbag.

[0004] In order to suck up and lay flat the airbag to be detected on the transparent flat plate as a whole, the length and width dimensions of the adsorption device are respectively close to the length and width dimensions of the airbag to be detected, resulting in a relatively large volume and weight of the adsorption device. And the driving device of the device for detecting the airbag is only connected to the adsorption device through the cylinder shaft of a single lifting cylinder, and the weight of the airbag is superimposed on the adsorption device during the conveying process, which will further increase the pressure at the connection between the adsorption device and the cylinder shaft, and may affect the stability of the connection structure between the driving device and the adsorption device, thus resulting in insufficient stability during the airbag conveying process.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] The present invention provides a vehicle airbag size detection device for solving the problem of how to improve the stability of the connection structure between the driving device 6 and the adsorption device 5.

[0038] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 as shown in Figure 1 is a perspective view of the vehicle airbag size detection device in the embodiment, Figure 2 is a schematic diagram of the adsorption device moving above the feeding table in the embodiment, Figure 3 is a schematic diagram of the adsorption device moving between the feeding table and the detection table in the embodiment, Figure 4 is a schematic diagram of the adsorption device moving to the first position above the detection table in the embodiment, Figure 5 is a schematic diagram of the adsorption device moving to the second position above the detection table in the embodiment. The vehicle airbag size detection device includes a frame 1, a feeding table 2, a detection table 3, a vision detection device 4, an adsorption device 5 and a driving device 6.

[0039] Both the feeding table 2 and the detection table 3 are used for placing airbags.

[0040] The vision detection device 4 is installed above the detection table 3 for detecting the outer contour size of the airbag on the detection table 3.

[0041] The adsorption device 5 is used for adsorbing airbags.

[0042] The driving device 6 includes a first driving mechanism 61 and a second driving mechanism 62 mounted on the frame 1. Both the first driving mechanism 61 and the second driving mechanism 62 include a linkage mechanism. The linkage mechanism includes a driving member 63, a crank 64, and a connecting rod 65. The driving member 63 is mounted on the frame 1 and is circumferentially fixed or bolted to one end of the crank 64 through a pin shaft. The other end of the crank 64 is rotatably connected to one end of the connecting rod 65 through a rotating shaft, and the other end of the connecting rod 65 is rotatably connected to the adsorption device 5 through a rotating shaft. Wherein, the driving member 63 is used to drive the crank 64 and the connecting rod 65 to move towards the feeding table 2 or the detection table 3, so as to drive the adsorption device 5 to move between the feeding table 2 and the detection table 3.

[0043] When the vehicle airbag size detection device of the above technical solution is in use, first, the airbag to be tested is laid flat on the feeding table 2. The driving device 6 and the adsorption device 5 cooperate to suck up the airbag to be tested, and then move and lay flat the airbag to be tested on the detection table 3. Then, the adsorption device 5 releases the airbag to be tested, and the driving device 6 drives the adsorption device 5 back to its original position. At the same time, the vision detection device 4 detects the outer contour size of the airbag on the detection table 3. After the detection, the driving device 6 and the adsorption device 5 cooperate to suck up the tested airbag on the detection table 3 and put the tested airbag back on the feeding table 2. Finally, the adsorption device 5 releases the tested airbag. In this way, the driving device 6 of the vehicle airbag size detection device is connected to the adsorption device 5 through at least two connecting rods 65 of the first driving mechanism 61 and the second driving mechanism 62, and works together to drive the adsorption device 5 and the airbag to move towards or out of the detection table 3. Compared with the existing single-point connection, the connection structure between the driving device 6 and the adsorption device 5 of this detection device has better stability, thereby improving the stability of the airbag conveying process.

[0044] The above linkage mechanism may include one or more cranks 64. If there are two or more cranks 64 in the linkage mechanism, the cranks 64 of the linkage mechanism are evenly spaced and are all connected to the output shaft of the same driving member 63. In this way, one driving member 63 can drive multiple cranks 64 to rotate simultaneously. The above driving member 63 can use existing rotary driving devices such as stepping motors.

[0045] The number of cranks 64 and connecting rods 65 of the above linkage mechanism is the same and they are connected one by one. Moreover, the more the number of connecting rods 65, that is, the more connection points between the driving device 6 and the adsorption device 5, the more stable the airbag conveying process can be improved.

[0046] Refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, on the basis of the above embodiments, the driving device 6 further includes a first pull rod 66, a linkage plate 67 and a second pull rod 68. One end of the first pull rod 66 is rotatably connected to the frame 1 through a rotating shaft. The linkage plate 67 is rotatably connected to the rotating connection between the crank 64 and the connecting rod 65 of the first driving mechanism 61 through a rotating shaft. The two ends of the linkage plate 67 are respectively rotatably connected to the other end of the first pull rod 66 and one end of the second pull rod 68 through a rotating shaft. The other end of the second pull rod 68 is rotatably connected to the adsorption device 5 through a rotating shaft. The second pull rod 68 is located between the connecting rod 65 of the first driving mechanism 61 and the connecting rod 65 of the second driving mechanism 62. Among them, the first pull rod 66 and the crank 64 of the first driving mechanism 61 are distributed in parallel, the connecting rod 65 of the first driving mechanism 61 and the second pull rod 68 are distributed in parallel, and the rotating connection points of the second pull rod 68 and the connecting rod 65 with the adsorption device 5 are on the same straight line, so that the adsorption device 5 is horizontally distributed. In this way, the first pull rod 66, the linkage plate 67 and the second pull rod 68 cooperate to keep the adsorption device 5 always horizontally distributed, effectively avoiding the airbag tilting and rubbing against the surface of the detection table 3 or the feeding table 2 during the process of the conveying mechanism moving the airbag away from the detection table 3 or the feeding table 2, resulting in damage. Moreover, the cooperation of the first pull rod 66, the linkage plate 67 and the second pull rod 68 can further improve the stability of the connection structure between the driving device 6 and the adsorption device 5, thereby further improving the stability of the airbag conveying process.

[0047] The first pull rod 66 and the crank 64 of the first driving mechanism 61 are distributed in parallel, and the connecting rod 65 of the first driving mechanism 61 and the second pull rod 68 are distributed in parallel. Therefore, the above-mentioned first pull rod 66, linkage plate 67 and second pull rod 68 are mainly used to improve the conveying process of the airbag by the first driving mechanism 61. The connecting rod 65 of the second driving mechanism 62 can be set thicker than the connecting rod 65 of the first driving mechanism 61 to strengthen the driving process of the second driving mechanism 62.

[0048] Refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in an embodiment of the crank 64, a limiting portion 641 is provided on the crank 64 by integral connection or welding, etc. A limiting block 11 is provided on the frame 1 by threaded connection or welding, etc. The limiting block 11 is located on the rotation path of the limiting portion 641 and is used to abut against the limiting portion 641 to limit the rotation angle of the crank 64. In this way, the limiting block 11 can limit the rotation paths of the crank 64 of the first driving mechanism 61 and the crank 64 of the second driving mechanism 62 from overlapping, effectively avoiding interference and damage to the crank 64 and the connecting rod 65 of the first driving mechanism 61 and the second driving mechanism 62 during rotation, and can also combine to limit the stroke of the adsorption device 5 moving back and forth between the feeding table 2 and the detection table 3.

[0049] The above-mentioned limiting part 641 is arranged on the outer side wall of one end of the crank 64 connected to the driving part 63.

[0050] In this embodiment, each crank 64 corresponds to two limiting blocks 11. One limiting block 11 is arranged horizontally and is set as the horizontal limiting block 111, and the other limiting block 11 is arranged vertically and is set as the vertical limiting block 112. The horizontal limiting block 111 and the vertical limiting block 112 cooperate to limit the crank 64 of the first driving mechanism 61 and the second driving mechanism 62 to only be able to rotate 90°. The specific use process of the vehicle airbag size detection device in this embodiment is as follows: First, as Figure 2 shown, the driving part 63 of the first driving mechanism 61 drives the crank 64 to rotate upward from bottom to top towards the feeding table 2 until the crank 64 abuts against the corresponding vertical limiting block 112. At the same time, the driving part 63 of the second driving mechanism 62 drives the crank 64 to rotate downward from top to bottom towards the feeding table 2 until the crank 64 abuts against the corresponding horizontal limiting block 111, so that the connecting rods 65 of the first driving mechanism 61 and the second driving mechanism 62 cooperate to drive the adsorption device 5 to move towards the feeding table 2 and contact the airbag to be measured on the feeding table 2. After the adsorption device 5 adsorbs the airbag to be measured, as Figure 3 shown, the driving part 63 of the second driving mechanism 62 drives the crank 64 to rotate upward from bottom to top towards the detection table 3 until the crank 64 abuts against the corresponding vertical limiting block 112, so as to drive the adsorption device 5 to move obliquely upward from the feeding table 2 towards the detection table 3, thereby lifting the airbag to be measured and driving the airbag to be measured to move between the feeding table 2 and the detection table 3. Then, as Figure 4 shown, the driving part 63 of the first driving mechanism 61 drives the crank 64 to rotate downward from top to bottom towards the detection table 3, so as to drive the adsorption device 5 to move obliquely downward towards the detection table 3, so as to lower the airbag to be measured and drive the airbag to be measured to move from between the feeding table 2 and the detection table 3 to directly above the detection table 3. At this time, if when the crank 64 of the first driving mechanism 61 rotates downward from top to bottom to abut against the corresponding horizontal limiting block 111, the airbag to be measured is still above the detection table 3 and does not contact the top surface of the detection table 3, then as Figure 5 shown, the driving part 63 of the second driving mechanism 62 drives the crank 64 to rotate downward from top to bottom towards the feeding table 2 by a certain angle, so as to lower the airbag to be measured and place the airbag to be measured flat on the top surface of the detection table 3.

[0051] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, in an embodiment of the inspection table 3 and the vision inspection device 4, a light-emitting panel 31 is installed on the top surface of the inspection table 3 by means of screwing or bonding. The light-emitting panel 31 is used for placing the airbag to be tested and providing backlight for the airbag to be tested. The vision inspection device 4 includes a plurality of CCD cameras 41 arrayed on the frame 1. The shooting areas of the plurality of CCD cameras 41 overlap with each other and combine to form a complete vision inspection range, and the vision inspection range completely covers the light-emitting panel 31. In this way, the vision inspection range formed by combining the plurality of CCD cameras 41 can completely cover the light-emitting panel 31, ensuring that as long as the airbag to be tested is placed on the light-emitting panel 31, the vision inspection device 4 can comprehensively detect the entire outer contour size of the airbag to be tested without restricting the specific placement position of the airbag on the light-emitting panel 31. During the detection process, the light-emitting panel 31 emits light to provide backlight for the airbag to be tested, which can make the contour of the airbag clearer, improve the clarity of vision inspection, and thus improve the accuracy of the detection result.

[0052] The above-mentioned light-emitting panel 31 can use an existing LED light-emitting panel 31.

[0053] Refer to Figure 1 As shown, the vision inspection device 4 further includes a server (not shown in the figure) and a display screen 7. The server is electrically connected to the CCD camera 41 and the display screen 7. The CCD camera 41 transmits the image to the server, and the server compares it with a preset standard size range to determine whether the outer contour size of the airbag meets the requirements. The display screen 7 can display the shooting picture of the CCD camera 41 and the determination result of the server, facilitating the staff to intuitively see the detection result.

[0054] The above-mentioned CCD camera 41, server and display screen 7 can all use existing CCD cameras 41, servers and display screens 7.

[0055] Refer to Figure 1 As shown, in an embodiment of the feeding table 2, the feeding table 2 is located on one side of the inspection table 3. A conveyor belt 21 is installed on the feeding table 2. The conveyor belt 21 is used to convey the airbag to be tested towards the inspection table 3 and convey the tested airbag away from the inspection table 3. In this way, the conveyor belt 21 can automatically move the airbag to be tested to one side of the inspection table 3 so that the driving device 6 can transfer the airbag to be tested on the feeding table 2 to the inspection table 3 for testing. After testing, the conveyor belt 21 can automatically move the tested airbag to the good product turnover cart or the defective product turnover cart according to the test result, thus realizing the automatic loading and unloading of the airbag, greatly saving manpower.

[0056] The above-mentioned conveyor belt 21 can use an existing belt conveyor belt 21, and the conveying direction of the conveyor belt 21 is towards the inspection table 3.

[0057] Refer toFigure 1 As shown, in one embodiment of the adsorption device 5, the adsorption device 5 includes a frame body 51 and a plurality of vacuum suction cups 52 evenly spaced apart. The vacuum suction cups 52 are mounted on the frame body 51 by means of tight connection, screw connection or detachable connection, etc., and are used to adsorb the airbag. In this way, the adsorption device 5 adsorbs the airbag through the combination of a plurality of vacuum suction cups 52, can drive the airbag to move together, and the vacuum suction cups 52 can effectively avoid damaging the airbag.

[0058] The above-mentioned vacuum suction cups 52 can also be slidably connected to the frame body 51 so as to steplessly adjust the position of the vacuum suction cups 52. After adjustment, the vacuum suction cups 52 and the frame body 51 can be fastened by threaded members. The above-mentioned vacuum suction cups 52 can be connected to existing equipment such as a vacuum pump to provide the adsorption force for the vacuum suction cups 52 to adsorb the airbag.

[0059] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
