[0002] An aerostat is a flexible aircraft that relies mainly on buoyancy gas to achieve lift and flight. The flap welding of the aerostat capsule is a process of aligning the straight or curved flaps made of special reinforced flexible composite fabrics or plastic films in pairs and then hot-pressing and bonding them with welding equipment. The area where the edges of the two flaps are heat-sealed together is the weld. Weld accuracy, also known as welding accuracy, is one of the important factors in evaluating welding quality, and mainly includes weld width, seam size, flap misalignment size, etc.
[0003] At present, in the processing of aerostat bladders at home and abroad, the bladder welding quality inspection generally relies on manual visual or manual inspection, and there is a lack of proprietary automated bladder welding precision quality inspection equipment. Especially for medium and large-scale aerostat bladder weld inspection operations such as tens of meters or hundreds of meters in length, the shortcomings are mainly reflected in the following aspects:
[0004] First, the manual inspection data such as the slit size and misalignment size have large errors, and the measurement accuracy cannot be guaranteed.
[0005] Second, the shuttle-shaped curved capsule flaps that are tens of meters long are prone to irregular arc bulging when unfolded after welding. The arc bulging of the capsule body weld causes local deformation, which is not convenient for the precise detection of the capsule flap welds, especially for tiny seam defects and misalignment defects that exceed the standard by 0.1mm, and the detection efficiency is low.

[0029] The following is a clear and complete description of the technical solution in the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, the utility model airship bladder profiling welding detection system mainly includes an arc detection platform 1, a detection camera 2, an arc slide rail 3, a camera frame 4, an alarm 5, and a digital display control unit 6; the arc slide rail 3 is parallel to the arc detection platform 1 along the length direction, the detection camera 2 is installed at the lower end of the camera frame 4 to identify and detect the seam size and misalignment size of the bladder weld 7, the alarm 5 is fixed on the camera frame 4, and the digital display control unit 6 is connected to the detection camera 2, the alarm 5, a servo motor 8 for controlling the operation of the camera frame 4, and a vacuum pump for controlling the opening and closing of the vacuum adsorption hole 9 through cables or wires.
[0031] The arc detection platform 1 is used to carry and fix the capsule weld 7 and position the capsule weld 7 along the length direction. The arc detection platform 1 is a long arc shape. Through this contour design, it can adapt to the arc arching of the capsule weld 7 after it is unfolded, thereby ensuring that the capsule weld area is fully flattened. The span of the arc detection platform 1 is 10m, and the arch height of the arc detection platform 1 measured by the ground horizontal line is 1.5m. Based on this, the corresponding arc radius of the arc detection platform 1 can be calculated to be 13.1m. In order to make the capsule weld 7 with local arching on the detection table surface of the arc detection platform 1 The arc detection platform 1 is fully fitted and unfolded, and can be applied to the detection of the capsule weld 7 with a curvature radius ≥ 13.1m.

The arc detection platform 1 is made of tempered glass material to enhance the recognition and detection effect of the detection camera 2 on the capsule weld 7.
[0032] Vacuum adsorption holes 9 are distributed on the arc-shaped detection platform 1 . The diameter of the vacuum adsorption holes 9 is 8 mm. Each vacuum adsorption hole 9 is connected to a vacuum pump through an air pipe. The arc-shaped detection platform 1 fixes the capsule weld 7 through vacuum adsorption.
[0033] The detection camera 2 is used to identify and detect the size of the opening and the misalignment of the capsule weld 7. The detection camera 2 uses an industrial camera with a pixel of not less than 1000W and a frequency of not less than 5fps. The light source provides sufficient illumination for the industrial camera to make the detection information clearer and more accurate. The detection accuracy of the opening and the misalignment of the capsule weld 7 by the detection camera 2 can reach 0.1mm.
[0034] The arc-shaped slide rail 3 is used to carry the camera frame 4 so that the detection camera 2 can realize the arc motion trajectory operation. The arc-shaped slide rail 3 is placed on one side of the arc-shaped detection platform 1, and the two are precisely parallel along the length direction. The arc-shaped slide rail 3 and the arc-shaped detection platform 1 are not co-centered, but the arc-shaped slide rail 3 and the arc-shaped detection platform 1 have the same curvature. The span of the arc-shaped slide rail 3 is 10.5m and the arch height is 2m. This design can leave enough space for large capsules and capsule petals to move up to the arc-shaped detection platform 1.
[0035] The camera frame 4 is used to fix the detection camera 2. The camera frame 4 is an L-shaped beam frame that can be extended and retracted up and down, so that the vertical distance between the detection camera 2 and the table surface of the arc-shaped detection table 1 can be adjusted. The vertical beam of the L-shaped beam frame can move up and down along the guide hole of the horizontal beam. The maximum adjustable displacement up and down is 800mm. When the vertical beam is positioned at the height on the horizontal beam, it is locked with a locking screw; a servo motor 8 and a slider trolley 14 for driving the camera frame 4 to move are installed on the horizontal beam of the L-shaped beam frame. The camera frame 4 is installed on the slider trolley 14, and the output shaft of the servo motor 8 is connected to the driving wheel 10. The four driving wheels 10 of the slider trolley 14 are connected to the arc-shaped slide rail 3 rollers. A limit rod 15 is provided between the slider trolley 14 and the arc-shaped slide rail 3, one end of the limit rod 15 is fixed at the bottom of the slider trolley 14, and the ball at the other end of the limit rod 15 contacts the arc-shaped slide rail 3, so that the slider trolley 14 can run smoothly on the arc-shaped slide rail 3; the driving wheel 10 of the slider trolley 14 is driven by the servo motor 8 to realize the sliding of the camera frame 4 along the arc track of the arc-shaped slide rail 3, the sliding linear speed of the slider trolley 14 is 12m / min, and the movement speed of the servo motor 8 and the slider trolley 14 corresponds to the detection speed V of the precision quality of the capsule weld 7, and V is adjustable within 0~15m / min.
[0036] The alarm 5 uses a voice broadcaster with recording storage function and RS232 serial port control, which is fixed to the camera frame by a clamp, and is used to give a voice alarm prompt for the section where the seam size, misalignment size or excessive defects of the capsule weld 7 are detected. The voices such as "abnormal seam", "abnormal misalignment" and "abnormal detection" can be pre-recorded in the alarm 5. When the detection camera 2 detects that the seam size and misalignment size of the capsule weld 7 are abnormal, the alarm 5 can immediately receive the voice alarm command of the digital display control unit 6, and issue corresponding voice prompts: "abnormal seam" and "abnormal misalignment". When the above two abnormalities appear at the same position of the capsule weld 7 at the same time, a voice prompt is issued: "abnormal detection". When the size of the capsule weld is detected to be normal, no alarm prompt is issued.
[0037] The digital display control unit 6 adopts an industrial control host computer, such as a Senke brand SK-19GBQX industrial control host computer with a 19-inch screen, a hard disk capacity of 128G, and a memory of 4MB. It can realize two modes: automatic scanning detection mode and manual scanning detection operation for local detection. It can issue corresponding instructions to the servo motor 8 and the detection camera 2 to perform scanning monitoring tasks; it can issue information instructions of "opening abnormality", "misalignment abnormality", and "detection abnormality" to the alarm 5 online; it can generate a curve with the detection displacement length of the capsule weld 7 as the horizontal coordinate and the opening size or misalignment size as the vertical coordinate, and the position of the defect of the capsule weld 7 can be quickly found through the curve combined with the length scale on the arc detection platform 1; the digital display control unit 6 is provided with "capsule fixing" and "capsule releasing" buttons. Clicking the "capsule fixing" button controls the start of the vacuum pump, and the capsule weld 7 is fully fixed on the arc detection platform 1 through the vacuum adsorption hole 9. After the detection is completed, click the "capsule releasing" button to release the capsule 11 by stopping the operation of the vacuum pump, so as to carry out the detection of the next section of the capsule 11.
[0038] In order to clearly describe the inspection process of the bladder body weld 7, in this embodiment, the welding accuracy inspection of the bladder body weld 7 between the first bladder flap 12 and the second bladder flap 13 of the spherical bladder 11 is taken as an example. The welding point between the first bladder flap 12 and the second bladder flap 13 is provided with a splicing misalignment marking line 19, and serial number 20 is the seam edge line between the first bladder flap 12 and the second bladder flap 13.
[0039] The span of the arc detection platform 1 is 10m, the arch height is 1.5m, the arc radius of the arc detection platform 1 is 13.1m, and the arc length is 15.8m; the diameter of the capsule 11 is 30m, then the radius is 15m≥the arc radius of the arc detection platform 1 13.1m, so it can be ensured that the capsule weld 7 is fully fitted with the arc detection platform 1 without arching deformation; the length of the capsule weld area is about 47m, which can be scanned and detected three times, among which the weld width = weld strip width = 50mm, which is a fixed value, and the weld accuracy quality inspection criteria are: the seam size ≤1.5mm is qualified, and the seam size>1.5mm is an abnormality that exceeds the standard (i.e., a seam defect); the misalignment size ≤2.5mm is qualified, and the misalignment size>2.5mm is an abnormality that exceeds the standard (i.e., a misalignment defect).
[0040] The detection process of the aerostat bladder welding quality profiling detection system of the utility model is as follows:
[0041] (a) Move the first section of the flap weld 7 to the table of the arc-shaped inspection table 1 and unfold it so that the flap weld 7 just falls within the inspection area. The length of the first section of the flap weld 7 to be inspected = the arc length of the arc-shaped inspection table 1 = 15.8 m;
[0042] (b) Press the "capsule fixing" button on the digital display control unit 6 to open the vacuum adsorption hole 9 to adsorb and fix the capsule 11 on the surface of the arc-shaped detection table 1;
[0043] (c) adjusting the camera frame 4, and adjusting the vertical distance from the bottom lens of the detection camera 2 to the capsule weld 7 on the surface of the arc-shaped detection platform 1 to 20 mm;
[0044] (d) entering the code and weld batch of the capsule 11 on the digital display control unit 6;
[0045] (e) Input the detection speed V as 10 m / min on the digital display control unit 6;
[0046] (f) Select "auto scan" on the digital display control unit 6, and after pressing the run button, the detection camera 2 completes the scanning detection of the seam size and misalignment size of the capsule weld 7 within 95 seconds. During the detection process, the alarm 5 is immediately activated to issue an online voice alarm prompt when the seam size is greater than 1.5 mm and the misalignment size is greater than 2.5 mm, otherwise the alarm prompt is not activated; synchronously with the detection, the digital display control unit 6 generates the detection length displacement-seam size curve and the detection length displacement-misalignment size curve online, and the weld defect location of the capsule weld 7 can be traced on the spot based on the curve;
[0047] (g) After scanning this section, the following data are automatically generated on the digital display control unit 6: the detection length of the first section of the flap weld 7, the cumulative length of the seam defect, the seam defect PPM, and the misalignment defect PPM;
[0048] (h) Press the pause button on the digital display control unit 6 to detect that the horizontal axis length displacement in the length displacement-slit size curve is not cleared to zero;
[0049] (i) Repeat the above steps (a) to (h) to inspect the second and third sections of the valve welds 7, and then complete the precision inspection of the valve welds 7 of a batch of valves.
[0050] It is not difficult to see from the above embodiments that the pure scanning detection of the accuracy of the bladder weld 7 takes less than 5 minutes, which is more than five times more efficient than manual visual caliper detection, the detection work intensity is significantly reduced, and the detection accuracy is effectively guaranteed. In addition, quality inspection PPM data and inspection reports can be completed simultaneously.
