Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of splicing mechanism, in particular to a curved edge splicing mechanism suitable for flexible materials. BACKGROUND

[0002] The main bearing structure of the aerostat is called a capsule, which is an ellipsoidal body formed by splicing a plurality of capsule petals. The material of the capsule petals is mostly flexible composite material, and the edges of the capsule petals are irregular curves. The process of splicing adjacent capsule petals is actually a process of splicing and hot melting two curved edges of adjacent capsule petals. The splicing quality greatly determines the hovering time of the aerostat and affects the maximum pressure-bearing capacity of the capsule.

[0003] In the current processing process, adjacent flat capsule petals are gradually spliced into a curved surface by edge-to-edge splicing. The whole curved edge (the length may exceed 100 meters) is first fitted into several "straight edges" by manual operation, and then the segmented "straight edges" are spliced edge-to-edge and tensioned one by one. Finally, the "straight edges" are spliced by hot melting. In the above operation process, when the curved edge is fitted into the "straight edge" for butt joint, it may cause inconsistent gaps, material overlapping, wrinkles and other quality problems, which may cause air leakage or stress concentration after the capsule is inflated. In addition, manual operation is difficult and the processing efficiency is low.

[0035] The visual inspection module 6 is composed of two groups of parallel lasers with a distance of 1 mm, which can determine and confirm the relative position of the valve leaflets. After the hot melting is completed, the two valve leaflets pass through the visual inspection module with the curved edge splicing mechanism, and when the distance between the valve leaflets is less than the distance between the two groups of parallel lasers, it is determined that the quality of the hot melted valve leaflets is qualified.

[0036] The pre-heating melting mechanism 10 is short-time and short-distance heating.

[0040] The positioning mechanism 8 can control the relative position of the capsule flaps and the mechanism, control the flatness of the capsule flaps, and have a discharging function. During the movement of the curved edge splicing mechanism, the hot-melted area can be transported to the area outside the mechanism. The upper side of the positioning mechanism 8 is connected to the bottom of the rack 5 through the positioning support 801, and the lower side of the positioning support 801 is provided with a rotary bearing 802. One side of the rotary bearing 802 is provided with a second optical fiber sensor 803, and the lower side of the second optical fiber sensor 803 is provided with an angle control motor 804. One side of the angle control motor 804 is provided with a roller 805, and the inner side of the roller 805 is provided with a roller motor 806. The second sensor support 807 is provided on the side away from the angle control motor 804, and the lower side of the second sensor support 807 is connected with the compression spring 808. The lower side of the compression spring 808 is connected with the optical fiber sensor roller head 809, and the lower side of the optical fiber sensor roller head 809 is connected with the optical fiber sensor roller 810.

[0041] The upper side of the edge matching mechanism 11 is connected to the bottom of the rack 5 through the edge matching support 111, and the lower side of the edge matching support 111 is provided with an edge matching motor 112. The lower side of the edge matching motor 112 is provided with an edge matching motor support 113, and the two sides of the edge matching motor support 113 are respectively provided with a first adapter plate 114 and a second adapter plate 115. One side of the first adapter plate 114 is connected with a third sensor support 116, and the third sensor support 116 is provided with a third optical fiber sensor 117. The lower side of the edge matching motor support 113 is provided with a roller support 118, and the lower side of the roller support 118 is provided with a limiting screw 119. The lower side of the limiting screw 119 is provided with a positioning roller 120.

[0042] The edge matching mechanism 11 is provided with multiple groups. The edge matching mechanism 11 has a positioning function, can identify the edge line of the capsule flap in real time, and control the edge line of the capsule flap to always be on the set reference line. Figure 5 As shown in the drawings, the edge matching mechanism 11 has a tension control function, which can control the flatness of the capsule flaps. The edge matching mechanism 11 also has an interactive function, which interacts with the computer, and alarms in time when an abnormality occurs.

[0043] The hot sealing belt 12 and the capsule flap surface are attached with hot melt adhesive. When the adjacent capsule flap edges dynamically contact on the center line of the curved edge splicing mechanism, the hot sealing belt 12 is pasted and fixed by the hot pressure roller. The hot sealing belt 12 always maintains tension during the pasting process.

[0044] The lower side of the movement wheel 2 is provided with a track 14 matched with the movement wheel 2. The track 14 is used for the movement of the whole curved edge splicing mechanism.

[0045] As shown in the drawings, the lower side of the movement wheel 2 is provided with a track 14 matched with the movement wheel 2. The track 14 is used for the movement of the whole curved edge splicing mechanism. Figure 3The schematic diagram of the adjacent capsule lobe pair edges is shown. As Figure 4 The overall layout diagram when the curved edge splicing mechanism is in use is shown. When in use, the capsule lobe material is manually placed on both sides of the curved edge splicing mechanism in advance, and the position of the capsule lobe material is adjusted so that the edges of the adjacent capsule lobe materials to be heat-fused are symmetrical to the center line of the mechanism;

[0046] The curved edge splicing mechanism is started, and the two sides of the capsule lobe remain relatively static when the mechanism advances on the track. A plurality of edge alignment mechanisms 11 dynamically position and tension the edges through laser ranging, and finally pull the two capsule lobe edges (i.e., the parts to be heat-fused) to the center line. During the advancing process, the curved edge splicing mechanism advances while identifying, and the relative position of the capsule lobe is kept or adjusted in real time.

[0047] After the edges of the adjacent capsule lobes contact on the center line, the adjacent capsule lobes are preliminarily fixed and preliminarily heat-fused by the heat-fusion belt 12 and the sealing strip 13 through the pre-heat-fusion mechanism 10, and then the mechanism advances to the area where the material is not heat-fused. The pre-heat-fusion material reaches the heat-fusion mechanism area and continues to be pre-heat-fused.

[0048] After the pre-heat-fusion is completed, the heat-fusion belt, the capsule lobe, and the sealing strip advance with the mechanism to the heat-fusion mechanism, and the heat-fusion mechanism presses down to heat-weld the heat-fusion belt, the capsule lobe, and the sealing strip together, thereby completing the preliminary heat-fusion.

[0049] The capsule lobe after the heat-fusion advances with the mechanism to the cross-lobe heat-fusion mechanism 7 and is heat-fused again, thereby finally forming one capsule lobe from the two capsule lobes through heat-fusion, and the heat-fused capsule lobe is transported to an area outside the mechanism as the mechanism advances.

[0050] During the advancing process of the splicing mechanism, the visual inspection module 6 can judge and confirm the position of the capsule lobe through laser ranging, and the positioning mechanism 8 can provide tension to control the relative position of the capsule lobe and the splicing mechanism.

[0051] Therefore, the curved edge splicing mechanism for flexible materials can solve the problem of continuous edge alignment splicing of flexible curved edge materials and improve the edge alignment splicing quality and efficiency. The profile data of the arc edges / straight edges with different curvatures are uploaded in real time by the visual camera, the system controls the alignment gap of the two adjacent arc edges through the driving device, the arc edges are immediately heat-fused and fixed at the moment of dynamic contact, and the splicing efficiency is high.

[0052] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application but not to limit them. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
