[0049] The following refers to Figures 1 - 8 Describe the valve pocket positioning device 100 according to an embodiment of the present invention, which has a simple structure, low setting cost, simple operation, can improve the edge matching efficiency and welding efficiency of the valve pockets 4, and ensure the welding quality between the valve pockets 4.

[0050] As Figures 1 - 8 shown, the valve pocket positioning device 100 according to an embodiment of the present invention includes: two positioning base tapes 1 and a slider 3.

[0051] Each positioning base tape 1 is provided with an adhesive tape and teeth 2. The adhesive tapes of the two positioning base tapes 1 are arranged to be adhesively bonded to the two valve pockets 4 respectively. The slider 3 cooperates with the teeth 2 of the two positioning base tapes 1 to pull and fix or pull apart and separate the two positioning base tapes 1. The adhesive tape is configured to be adhesively separated from the corresponding valve pocket 4 when heated during the welding of the two valve pockets 4.

[0052] Among them, the bladder flap positioning device 100 can be used for an aerostat. An aerostat is a type of aircraft that is filled with a light gas (such as helium or hydrogen) inside and relies on or mainly relies on air static buoyancy to achieve lift-off. It is an aircraft that can perform flight missions in the space area 50m to 100km above sea level for a long time. Compared with other aircraft, it has the advantages of high flight altitude, low cost, and long hovering time. The aerostat can use the near-space balloon system to carry corresponding payloads to achieve application purposes such as high-altitude wind power generation, meteorological environment monitoring, regional communication, urban traffic monitoring, earth exploration, space observation, and high-altitude adventure tourism. The use effect is good and it can meet various use requirements.

[0053] Specifically, the bladder flap positioning device 100 is provided with two positioning basebands 1, which can be made of cotton yarn, chemical fiber, or mixed chemical fiber materials, etc. Both of the two positioning basebands 1 can be installed on the bladder flap 4 and can extend along the edge of the bladder flap 4. Each positioning baseband 1 can be provided with an adhesive tape, and the adhesive tape is made of a sticky material. One side of the adhesive tape can be adhesively connected to the positioning baseband 1, and the other side of the adhesive tape can be adhesively connected to the bladder flap 4. Thus, the positioning baseband 1 can be fixedly connected to the bladder flap 4 through the adhesive tape. Two positioning basebands 1 are provided, and both of the two positioning basebands 1 can be adhesively bonded to the edge of the bladder flap 4 through the adhesive tape, and the installation is convenient.

[0054] Furthermore, each positioning baseband 1 can be provided with a zipper tooth 2, which can be made of metal material, nylon material, etc. The zipper tooth 2 can be arranged at the edge of the positioning baseband 1 and is arranged to extend along the length direction of the positioning baseband 1. Two positioning basebands 1 are provided, that is, zipper teeth 2 are arranged at the edges of both of the two positioning basebands 1. Two bladder flaps 4 are provided, and the two bladder flaps 4 and the two positioning basebands 1 are arranged in one-to-one correspondence. Both of the two positioning basebands 1 can be adhesively bonded to the edge of the corresponding bladder flap 4, and the positions where the two positioning basebands 1 are adhesively bonded are close to each other. When the two positioning basebands 1 are adhesively bonded to the corresponding bladder flap 4, the zipper teeth 2 of both of the two positioning basebands 1 need to be distributed on the sides of the two positioning basebands 1 close to each other.

[0055] And the bladder flap positioning device 100 is also provided with a slider 3, which can also be made of metal material, nylon material, etc. The slider 3 can cooperate with the zipper teeth 2 of the two positioning basebands 1. That is, after the two positioning basebands 1 are adhesively bonded to the edges of the two bladder flaps 4, the slider 3 can place parts of the two zipper teeth 2 into the groove-like structures on both sides of the slider 3, so that the slider 3 can clamp the zipper teeth 2 on both sides, and the slider 3 can slide along the length direction of the positioning baseband 1 by means of a pull tab to pull the two zipper teeth 2 together or apart. Thus, the two positioning basebands 1 can be pulled together and fixed or pulled apart and separated. Both of the two positioning basebands 1 are adhesively bonded to the corresponding bladder flap 4. By pulling the two positioning basebands 1 together and fixing them, the edges of the two bladder flaps 4 can be pulled together.

[0056] In addition, the edges of the two flaps 4 can be connected by welding after being pulled together. Hot air positioning welding, etc. can be used to complete the welding of the flaps 4. The operation is simple, and the edge alignment efficiency of the flaps 4 can be improved, the edge alignment accuracy can be improved, and the welding efficiency can be improved.

[0057] At the same time, the positioning base tape 1 can be bonded to the non-welding surface of the flap 4 by the adhesive tape, that is, the welding of the flap 4 is performed on the side of the flap 4 away from the positioning base tape 1, and hot air positioning welding can be used between the two flaps 4, and heat will be generated during welding. The adhesive tape can be constructed to be heated when the two flaps 4 are welded so as to be bonded and separated from the corresponding flap 4, so that the user can remove the positioning base tape 1 from the flap 4 while performing the bonding operation, which is convenient for operation, can improve production efficiency, and can ensure welding quality.

[0058] According to the flap positioning device 100 of the embodiment of the present invention, the slider 3 cooperates with the chain tooth 2 to pull the positioning base belt 1 together to fix or pull it apart to separate it, thereby driving the corresponding flap 4 to align the edges for subsequent welding and other operations. It has a simple structure, low setting cost, and simple operation. It can improve the aligning efficiency and welding efficiency of the flap 4. When the flap 4 is welded, the adhesive tape is heated and bonded to and separated from the corresponding flap 4, thereby ensuring the welding quality between the flaps 4, achieving better use effect and wider application range.

[0059] In some embodiments, the adhesive tape is constructed as a double-sided tape, and the adhesive tape has a first adhesive surface and a second adhesive surface facing away from each other, the first adhesive surface is attached to the positioning base tape 1, and the second adhesive surface is suitable for attaching to the capsule valve 4.

[0060] Specifically, the positioning base tape 1 is adhered to the corresponding capsule flap 4 by means of an adhesive tape, one side of the adhesive tape is connected to the positioning base tape 1, and the other side of the adhesive tape is connected to the capsule flap 4, thereby fixing the positioning base tape 1 to the capsule flap 4, and the adhesive tape is constructed as a double-sided tape, that is, both sides of the adhesive tape are adhesive, one side of the adhesive tape can be bonded and connected to the positioning base tape 1, and the other side of the adhesive tape can be bonded and connected to the capsule flap 4, thereby bonding the positioning base tape 1 to the corresponding capsule flap 4, and the installation method is convenient and can reduce the setting cost.

[0061] Furthermore, the two adhesive surfaces of the adhesive tape are arranged back to back, that is, the two adhesive surfaces are arranged on two surfaces of the adhesive tape that are directly opposite to each other, and the two adhesive surfaces are respectively arranged as a first adhesive surface and a second adhesive surface. The first adhesive surface is in contact with the positioning base tape 1, so that the adhesive tape can be bonded and connected to the positioning base tape 1 through the first adhesive surface, and the second adhesive surface is in contact with the capsule flap 4, so that the adhesive tape can be bonded and connected to the capsule flap 4 through the second adhesive surface, thereby ensuring the reliability of the installation of the positioning base tape 1 on the capsule flap 4, and ensuring that the capsule flap 4 will not shift during welding, thereby ensuring the welding reliability.

[0062] In some embodiments, the width of the first adhesive surface is less than the width of the positioning baseband 1.

[0063] Specifically, the adhesive tape is provided with a first adhesive surface, the first adhesive surface is adhesively connected to the positioning baseband 1, and the width of the first adhesive surface is set to be less than the width of the positioning baseband 1. The positioning baseband 1 extends along the edge of the bladder flap 4, and the adhesive tape can be set to extend along the length direction of the positioning baseband 1. The adhesive tape is adhesively connected to the positioning baseband 1 through the first adhesive surface.

[0064] Further, the positioning baseband 1 is further provided with a zipper tooth 2. The zipper tooth 2 is arranged on one side of the positioning baseband 1 along the width direction and extends along the length direction of the positioning baseband 1. That is, the extending direction of the adhesive tape is the same as the extending direction of the zipper tooth 2. The two zipper teeth 2 of the two positioning basebands 1 can cooperate with the slider 3 to pull and fix or separate the two positioning basebands 1. Setting the width of the first adhesive surface to be less than the width of the positioning baseband 1 can further avoid the zipper tooth 2 and ensure the installation reliability of the zipper tooth 2, and can also avoid the slider 3 and ensure the movement reliability of the slider 3.

[0065] In some embodiments, the width of the first adhesive surface is greater than or equal to half of the width of the positioning baseband 1.

[0066] Specifically, the adhesive tape is adhesively connected to the positioning baseband 1 through the first adhesive surface, and the width of the first adhesive surface is set to be greater than or equal to half of the width of the positioning baseband 1. That is, the width of the first adhesive surface can be set to be greater than half of the width of the positioning baseband 1 or equal to half of the width of the positioning baseband 1. The first adhesive surface can be adhesively bonded to the side of the positioning baseband 1 away from the zipper tooth 2 or located in the middle of the positioning baseband 1.

[0067] Further, when the slider 3 cooperates with the zipper tooth 2 and pulls and fixes the two zipper teeth 2, a pulling force along the width direction of the positioning baseband 1 will be generated on the zipper tooth 2. This pulling force can be conducted along the positioning baseband 1 to the adhesive tape, and the pulling force will cause a relative displacement trend between the positioning baseband 1 and the bladder flap 4. Setting the width of the first adhesive surface to be greater than or equal to half of the width of the positioning baseband 1 can improve the connection reliability between the adhesive tape and the positioning baseband 1, avoid the influence of the pulling force on the bonding position of the positioning baseband 1, and further avoid the change of the welding position between the two bladder flaps 4, improve the welding reliability, and ensure the welding quality.

[0068] In some embodiments, the positioning baseband 1 has a first side edge 11 and a second side edge 12 that face away from each other. The zipper tooth 2 is arranged on the first side edge 11, and the adhesive tape is located in the area of the positioning baseband 1 close to the second side edge 12.

[0069] Specifically, the positioning base band 1 is bonded to the flap 4 by an adhesive tape, and the positioning base band 1 is provided with a chain tooth 2, and the chain tooth 2 is fixedly installed at a side edge of the positioning base band 1 along the width direction, and the chain teeth 2 of the two positioning base bands 1 are arranged on the side of the two positioning base bands 1 close to each other, and the positioning base band 1 is provided with a first side edge 11 and a second side edge 12 which are opposite to each other in the width direction. When the two positioning base bands 1 are respectively bonded to the corresponding flaps 4, the first side edges 11 of the two positioning base bands 1 are arranged close to each other, and the second side edges 12 of the two positioning base bands 1 are arranged away from each other.

[0070] Furthermore, the chain tooth 2 of the positioning base tape 1 can be fixedly installed at the first side edge 11 of the positioning base tape 1, and the chain tooth 2 is arranged along the extension direction of the first side edge 11, the adhesive tape is bonded to the positioning base tape 1, and the adhesive tape is extended along the second side edge 12, the adhesive tape is bonded to the area of ​​the positioning base tape 1 close to the second side edge 12, the first side edge 11 is parallel to the second side edge 12, so that the chain tooth 2 and the adhesive tape are also parallel, and are spaced apart and distributed on both sides of the positioning base tape 1, so that the adhesive tape can avoid the chain tooth 2 to ensure the operational reliability of the chain tooth 2.

[0071] And if Figures 1 - 3 As shown, the link teeth 2 are constructed as tooth structures, the tooth structures of the two link teeth 2 are staggered, and the pull head 3 can clamp the link teeth 2 on both sides, so as to slide between the two link teeth 2 with the help of the pull tab, so that the tooth structures of the two link teeth 2 can be engaged, and then the two positioning base bands 1 can be pulled together and fixed. The structure is simple and the connection reliability of the two positioning base bands 1 can be ensured.

[0072] In some embodiments, the edge of the adhesive tape is flush with the second side edge 12 .

[0073] Specifically, the positioning base tape 1 is provided with a first side edge 11 and a second side edge 12, and the first side edge 11 and the second side edge 12 are distributed in parallel and spaced apart along the width direction of the positioning base tape 1, and the link tooth 2 is fixedly installed along the first side edge 11, and the edge of the adhesive tape is flush with the second side edge 12, so that the link tooth 2 and the adhesive tape are also distributed in parallel and spaced apart along the width direction of the positioning base tape 1.

[0074] When the slider 3 cooperates with the chain tooth 2 and the two chain teeth 2 are pulled together and fixed, a pulling force will be generated on the chain tooth 2 along the width direction of the positioning base tape 1. The pulling force can be transmitted to the adhesive tape through the chain tooth 2. The chain tooth 2 and the adhesive tape are set to be parallel, so that the length of the transmission path of the pulling force transmitted from the chain tooth 2 to the adhesive tape is the same, and then the pulling force at each part of the adhesive tape is the same, avoiding problems such as excessive local force on the adhesive tape, resulting in bonding failure, etc., improving the installation reliability of the positioning base tape 1, and then improving the welding reliability, ensuring the welding effect.

[0075] In some embodiments, the adhesive tape is configured as a heat-sensitive pressure-sensitive adhesive tape.

[0076] Specifically, the positioning base tape 1 can be adhered to the edge of the corresponding bladder flap 4 through the adhesive tape, and the bladder flap 4 is provided with a welding surface and a non-welding surface. The positioning base tape 1 can be installed on the non-welding surface of the corresponding bladder flap 4. Both bladder flaps 4 can be adhered with the positioning base tape 1. And before welding, the two positioning base tapes 1 can be pulled together and fixed through the slider 3 so that the edges of the welding surfaces of the two bladder flaps 4 are fitted and aligned. The user can perform hot air positioning welding on the edges of the two bladder flaps 4 on the welding surface.

[0077] Furthermore, the adhesive tape is configured as a heat-sensitive pressure-sensitive adhesive tape and can be made of materials such as acrylate oligomers. When the temperature of the heat-sensitive pressure-sensitive adhesive tape rises, its adhesive performance decreases. When the user performs hot air welding on the welding surface of the bladder flap 4, the heat can be conducted through the bladder flap 4 to the non-welding surface, and then the heat-sensitive pressure-sensitive adhesive tape can be heated up. At this time, the viscosity of the heat-sensitive pressure-sensitive adhesive tape decreases, and the user can directly remove the heat-sensitive pressure-sensitive adhesive tape. The operation is convenient, the production efficiency can be improved, and the removed heat-sensitive pressure-sensitive adhesive tape can be stored through the release paper or release film so that the adhesive tape can be reused, saving production costs and improving environmental protection.

[0078] The present invention also proposes a method for positioning bladder flaps.

[0079] According to the method for positioning bladder flaps of the embodiments of the present invention, as Figure 4 shown, the method for positioning bladder flaps is applicable to the bladder flap positioning device 100 of any one of the above, and the method for positioning bladder flaps includes:

[0080] S1. Adhere the adhesive tapes of the two positioning base tapes 1 to the two bladder flaps 4 respectively;

[0081] S2. Pull and position the chain teeth 2 of the two positioning base tapes 1 so that the weld edges of the two bladder flaps 4 are aligned;

[0082] S3. Perform positioning welding on the weld edges of the two bladder flaps 4 and separate the adhesive tape from the corresponding bladder flap 4;

[0083] S4. Remove the two positioning base tapes 1 and perform strengthening welding on the two bladder flaps 4.

[0084] Specifically, the aerostat is provided with an envelope which is used to contain gas and is mainly made of ultra-thin flexible composite materials. When the envelope is processed, the envelope material needs to be first cut into the shape of envelope flaps 4, and positioning base tapes 1 can be respectively adhered to two adjacent envelope flaps 4. The positioning base tapes 1 can be connected to the corresponding envelope flaps 4 through adhesive tapes, and the two positioning base tapes 1 are adhered to the edges of the corresponding envelope flaps 4. The teeth 2 of the two positioning base tapes 1 are arranged close to each other, and the slider 3 can be clamped between the two teeth 2. When the slider 3 slides between the two teeth 2, the two positioning base tapes 1 can be pulled together and fixed, and thus the weld edges of the two envelope flaps 4 can be aligned.

[0085] Furthermore, the two positioning base tapes 1 are both adhered to the non-welded surfaces of the envelope flaps 4. After the weld edges of the two envelope flaps 4 are aligned, the two envelope flaps 4 can be turned over to position-weld the weld edges of the welded surfaces of the two envelope flaps 4. During the welding process, the temperature at the welds and the weld edges of the two envelope flaps 4 rises. At this time, the adhesive performance of the adhesive tape decreases, and the user can directly remove the two positioning base tapes 1. After the position-welding is completed, the welds of the two envelope flaps 4 can be strengthened by welding to ensure the reliability of the connection between the two envelope flaps 4. This welding method is simple to operate, can improve production efficiency, and can ensure welding reliability, so as to ensure that the aerostat can stay in the air for a long time and improve the use effect.

[0086] According to the envelope flap positioning method of the embodiment of the present invention, by the cooperation of the slider 3 and the teeth 2, the positioning base tape 1 is pulled together and fixed or pulled apart and separated, and thus the corresponding envelope flap 4 can be driven to be opposite to the edge for subsequent operations such as welding. The structure is simple, the setting cost is low, the operation is simple, the edge alignment efficiency and the welding efficiency of the envelope flap 4 can be improved, and the adhesive tape is thermally separated from the corresponding envelope flap 4 during the welding of the envelope flap 4, and thus the welding quality between the envelope flaps 4 can be ensured, and the use effect is better and the applicable range is wider.

[0087] In some embodiments, as Figure 5 shown, the envelope flap positioning method further includes:

[0088] S5. Before the adhesive tape is adhered to the two envelope flaps 4;

[0089] S6. Turn the non-welded surface of the envelope flap 4 upwards and mark the alignment mark line.

[0090] Specifically, the positioning baseband 1 can be adhesively connected to the corresponding bladder flap 4 through an adhesive tape. The bladder flap 4 is provided with a welding surface and a non-welding surface. The positioning baseband 1 is installed on the non-welding surface of the bladder flap 4. That is, before the adhesive tape is adhered to the two bladder flaps 4, the two bladder flaps 4 need to be flipped to the non-welding surface so that the non-welding surface of the bladder flap 4 faces upward. And before the adhesive tape is adhered to the corresponding bladder flap 4, alignment marking lines need to be marked at the weld edges of the bladder flap 4. The alignment marking lines are generally drawn with a water-based pen or an oil-based pen, which is convenient for the alignment of the welding edges of the two bladder flaps 4, ensuring the accuracy of the installation position of the adhesive tape, thereby improving the welding efficiency. And by drawing the alignment marking lines on the non-welding surface, it can be avoided that the pigments and organic solvents in the alignment marking lines are welded into the welding surface together during welding, which affects the bonding performance of the welding adhesive and the structural strength of the bladder flap 4, and can improve the welding quality.

[0091] In some embodiments, adhesively connecting the adhesive tapes of the two positioning basebands 1 to the two bladder flaps 4 respectively includes: adhesively connecting the adhesive tape to the non-welding surface of the bladder flap 4, and making the chain teeth 2 of the positioning baseband 1 coincide with the weld edge of the bladder flap 4, and making the starting point of the chain teeth 2 coincide with the starting point of the weld edge.

[0092] Specifically, the bladder flap 4 is provided with a welding surface and a non-welding surface. The positioning baseband 1 can be adhesively connected to the welding surface of the bladder flap 4 through an adhesive tape. And after the two positioning basebands 1 are fixed by pulling the pull head 3, the user can perform positioning welding on the welding surface of the bladder flap 4. When the user installs the positioning baseband 1 on the non-welding surface of the bladder flap 4, the two positioning basebands 1 need to be arranged at the weld edges of the two bladder flaps 4, and the chain teeth 2 of the positioning baseband 1 need to coincide with the weld edge of the bladder flap 4, and the starting point of the chain teeth 2 needs to coincide with the starting point of the weld edge. Thus, after the pull head 3 pulls and fixes the two chain teeth 2, all parts of the two weld edges can be accurately joined together, avoiding problems such as gaps or overlaps after the two bladder flaps 4 are welded, and ensuring the welding quality.

[0093] And when the pull head 3 slides between the two chain teeth 2, both of the two chain teeth 2 are subjected to a pulling force in the width direction of the positioning baseband 1. This pulling force can be transmitted to the two bladder flaps 4 through the positioning baseband 1, so that the two bladder flaps 4 can approach each other in the width direction of the positioning baseband 1, thereby avoiding problems such as misalignment of the weld edges caused by the two bladder flaps 4 being stressed in the length direction of the positioning baseband 1, and ensuring the docking accuracy of the weld edges.

[0094] In some embodiments, as Figure 6 shown, the pulling and positioning of the chain teeth 2 of the two positioning basebands 1 includes:

[0095] S21. If the alignment marking lines of the two bladder flaps 4 are not aligned longitudinally;

[0096] S22. Adjust the longitudinal biting position of the teeth 2 of the two positioning base tapes 1 to calibrate the alignment marking lines of the two sac valves 4.

[0097] Specifically, alignment marking lines can be drawn on the non-welded surfaces of the two sac valves 4, and the positioning base tapes 1 can be adhered to the non-welded surfaces of the sac valves 4 according to the alignment marking lines. Then, the slider 3 can be pulled to join the welded edges of the two sac valves 4. If the alignment marking lines of the two sac valves 4 are not aligned longitudinally after the slider 3 pulls and fixes the two positioning base tapes 1, the two positioning base tapes 1 can be separated by pulling the slider 3. After the two teeth 2 are separated, the longitudinal biting position of the teeth 2 can be adjusted to calibrate the alignment marking lines of the two sac valves 4. The calibration method is simple and can be carried out before welding, avoiding repeated welding, improving the welding efficiency, and ensuring the welding quality.

[0098] In some embodiments, as Figure 7 shown, the sac valve positioning method further includes:

[0099] S7. After removing the two positioning base tapes 1;

[0100] S8. Wipe off the alignment marking lines.

[0101] Specifically, the positioning base tape 1 is adhered to the non-welded surface of the corresponding sac valve 4 through an adhesive tape. During welding, the sac valve 4 is heated, and the viscosity of the adhesive tape decreases. The user can remove the positioning base tape 1 relative to the sac valve 4. After the user removes the two positioning base tapes 1 of the two sac valves 4, the alignment marking lines can be wiped with anhydrous alcohol to erase the alignment marking lines. The alignment marking lines are generally drawn with a water-based pen or an oil-based pen. Erasing the alignment marking lines can avoid the alignment marking lines affecting the structural strength of the sac valve 4 and ensure the reliability of the sac valve 4 in use.

[0102] In some embodiments, positioning welding of the weld edges of the two sac valves 4 includes: performing hot air positioning welding on the weld edges of the two sac valves 4 to heat and position the welding surface and the welding tape through hot air welding.

[0103] Specifically, the weld edges of the two sac valves 4 can be aligned and joined through the two positioning base tapes 1. After the two weld edges are aligned and joined, hot air welding can be performed on the weld edges of the two sac valves 4 to weld and position the two weld edges. During welding, the welding tape can be placed between the two weld edges, and as welding progresses, the welding tape melts, and then the two weld edges can be connected. The operation is convenient and can ensure the accuracy of the connection of the two sac valves 4 by welding.

[0104] In some embodiments, strengthening the welding of the two sac valves 4 includes: performing strengthening welding on the two sac valves 4 through hot melt welding or high-frequency welding.

[0105] Specifically, two positioning basebands 1 are both bonded to the non-welded surface of the bladder flap 4. After aligning the weld edges of the two bladder flaps 4, hot air positioning welding can be performed on the weld edges of the welded surfaces of the two bladder flaps 4. After welding, the two positioning basebands 1 can be directly removed. And after the hot air positioning welding is completed, hot melt welding or high-frequency welding can be performed on the welds of the two bladder flaps 4 to strengthen the welds, ensuring the reliability of the connection between the two bladder flaps 4, so as to ensure that the aerostat can stay in the air for a long time and improve the use effect.

[0106] And as Figure 8 shown, it is the complete steps of the bladder flap positioning method, and its specific process is as follows:

[0107] Place the non-welded surface of the bladder flap 4 material upward, and cut the bladder flap 4 with the required shape and size according to the aerostat structure. Draw alignment marking lines at the edges of the non-welded surface of the bladder flap 4 with a water-based pen or an oil-based pen, and lay the bladder flap 4 with the alignment marking lines drawn flat. The alignment marking lines are drawn at the edges of the bladder flap 4. Users can bond the positioning baseband 1 to the corresponding bladder flap 4 according to the alignment positioning lines, and can fix the chain teeth 2 of the two positioning basebands 1 by the pull head 3 to splice the weld edges of the adjacent two bladder flaps 4. And after the weld edges of the adjacent two bladder flaps 4 are spliced, the two bladder flaps 4 can be flipped to place the welded surfaces of the two bladder flaps 4 upward.

[0108] At this time, hot air positioning welding can be performed on the welds of the two bladder flaps 4. At the same time, the viscosity of the adhesive tape decreases due to heat, and users can separate the positioning baseband 1 from the corresponding bladder flap 4. After removing the positioning baseband 1, users can wipe off the alignment positioning lines with anhydrous alcohol, etc. And after the wiping is completed, users can perform hot melt welding or high-frequency welding to strengthen the welds. The overall operation is convenient, which can improve the welding efficiency and qualification rate of the bladder flap 4 and ensure the welding quality.
