Description

Technical Field

[0001] This application relates to the field of flexible material welding and processing technology, and in particular to a flexible material welding equipment and welding system. Background Technology

[0002] In the field of flexible material welding and processing, the welding of curved components such as airship capsules and large inflatable membrane structures has always been a technical challenge. In the production and manufacturing process of flexible materials such as airship capsules, hot pressing the edges of high-performance material pieces to form welds is a key process step.

[0003] Because the airship capsule is usually a complex curved surface structure such as a sphere or ellipsoid, the heat-sealing area of ​​adjacent pieces is often in the form of mutually opposing curves on the plane, which makes it difficult to locate the weld.

[0004] In the existing technology, the processing of airship capsule welds is mainly completed by intermittent or continuous equipment, which relies on operators to position the edges of the cut pieces. This positioning method is difficult to adapt to curved welds due to the difficulty of manual or traditional mechanical positioning, resulting in technical problems such as large weld deviations, long processing time, and insufficient positioning accuracy.

[0005] To address the aforementioned issues, this application proposes a method that uses zipper bonding and positioning to quickly align the edges of the cut pieces to be welded before welding. However, currently, there is a lack of welding equipment that can integrate zipper opening and closing, weld processing, and zipper removal, which cannot meet the high-efficiency, high-quality welding processing requirements of flexible materials, especially airship capsules.

[0006] Therefore, those skilled in the art urgently need to develop an integrated flexible material welding equipment and system that can achieve high-precision positioning, continuous welding, and rapid removal of zipper tape. Utility Model Content

[0007] The purpose of this invention is to provide a flexible material welding equipment and welding system to solve the problem of rapid welding of flexible material pieces with zippers, achieve high-precision positioning, continuous welding and rapid zipper removal, and meet the processing requirements of high-quality welds.

[0008] The technical solution adopted by this application to solve its technical problem is as follows: On the one hand, a flexible material welding device is provided, wherein the flexible material includes at least two pieces to be welded, and a zipper tape is bonded to the surface edge of the pieces to be welded. The zipper tape and the zipper pull are pulled together to achieve weld seam positioning of the pieces to be welded on the welding device. The welding device includes: a frame; a welding execution mechanism disposed on the frame and a welding table located below the welding execution mechanism; a feeding mechanism located at one end of the welding table and a driving mechanism located at the other end of the welding table; a zipper pull holder disposed on the frame for fixing the zipper pull; a zipper tape groove for accommodating the zipper tape teeth after being pulled together; and a zipper tape removal mechanism disposed below the outlet of the zipper tape groove for separating and removing the heated zipper tape from the weld seam surface.

[0009] Furthermore, the welding equipment is divided into a positioning preparation area, a welding heat sealing area, a cooling and shaping separation area, and a power area along the material conveying direction; the feeding mechanism and the zipper head holder are located in the positioning preparation area, the zipper tape removal mechanism is located in the cooling and shaping separation area, and the driving mechanism is located in the power area.

[0010] Furthermore, the drive mechanism includes a driving wheel and a driven wheel, and the driven wheel is linked to the welding actuator through an elastic component.

[0011] Furthermore, the welding actuator includes a heater located in the welding heat sealing zone and a cooler located in the cooling and shaping separation zone. The heater is located above the zipper belt groove, and the cooler is located between the heater and the driven wheel. A thermal isolation structure is provided between the heater and the cooler.

[0012] Furthermore, the zipper tape groove includes a first groove located in the positioning preparation area and a second groove located in the welding heat sealing area, wherein the length center line of the first groove and the length center line of the second groove are collinear.

[0013] Furthermore, the zipper tape removal mechanism includes at least one zipper separation roller located below the cooling and shaping separation zone. The zipper tape separated from the outlet of the zipper tape groove enters the drive mechanism at the other end of the welding table via the zipper separation roller, and the zipper tape is removed from the weld surface under the drive of the drive mechanism.

[0014] Furthermore, the rotational speed of the zipper separating roller is matched with the speed of the drive mechanism.

[0015] Furthermore, the feeding mechanism includes a welding strip feeding mechanism, which includes a welding strip feeding tray and a limiter for guiding the welding strip. The center plane of the receiving groove of the limiter is in the same vertical plane as the center plane of the first chute and the second chute.

[0016] Furthermore, after being guided by the limiter, the welded strip moves synchronously with the pulled-closed zipper strip along the zipper strip groove, and the center of the weld is positioned by the limiting effect of the zipper strip teeth in the zipper strip groove.

[0017] Furthermore, the welding equipment also includes a guide platform mounted on a frame, and the guide platform is provided with the first chute.

[0018] Furthermore, the welding equipment also includes a first roller group located in the welding heat sealing zone and a second roller group located in the cooling and shaping separation zone. Each roller in the first roller group has a radial annular groove at its axial center, and each radial annular groove forms the second sliding groove.

[0019] This application also provides a flexible material welding system, including the flexible material welding equipment and control system described in any of the above embodiments. The control system is used to coordinate welding parameters with the zipper tape removal rhythm. The welding parameters include, but are not limited to, the operating temperature of the heater and cooler, the operating pressure of the welding actuator, and the rotational speed of the drive mechanism.

[0020] Compared with the prior art, the advantages of the technical solution of this application are as follows:

[0021] The welding equipment, system, method, and process for flexible materials provided in this application first involve bonding a zipper tape to the surface edge of the cut piece to be welded. After two adjacent cut pieces to be welded are pulled together for a certain length using the cooperation of the zipper pull and the zipper tape, the zipper pull is fixed to the puller holder. The pulled zipper tape is then placed in the zipper tape groove, achieving rapid alignment and positioning of the weld seam area of ​​the cut piece. The starting end of the pulled zipper tape extends to the drive wheel of the drive mechanism via the zipper tape removal mechanism, while the cut piece is placed on the welding table. At this point, the welding tape is taken out from the welding tape feeding mechanism and guided by the limiter to be placed on the weld seam, extending to the drive wheel of the drive mechanism.

[0022] Then, control the welding actuator to make the second actuator move downward, and the driven wheel and the driving wheel make pressure contact, pressing the closed welding cut piece starting section, welding strip and separated zipper strip between the driven wheel and the driving wheel, and move to the left under the drive mechanism.

[0023] Secondly, the heater is controlled to heat up and reach the set temperature parameters; the first actuator is controlled to move downward, and at the same time the drive wheel of the drive mechanism rotates. The welding piece moves to the left under the drive mechanism. The zipper pull pulls the zipper tape of the two adjacent pieces to be welded together. The pieces to be welded and the welding tape enter the heater below at the same time. A weld is formed by hot pressing. The weld enters the cooler below for cold pressing and shaping. Simultaneously, the heated zipper tape is separated from the welding piece by the zipper separation roller of the zipper tape removal mechanism. Under the drive mechanism, it moves to the left and enters the collection box.

[0024] Finally, the above welding process continues, enabling rapid and accurate positioning, stable and reliable welding of the cut piece with zipper strap, and simultaneously removing the zipper, resulting in a high-precision, high-quality weld that meets the high-efficiency, high-quality processing requirements of flexible materials such as large airship capsules.

[0048] Example 1

[0049] Please see Figures 1-5 As shown, this embodiment provides a flexible material welding device. The flexible material includes at least two pieces 50 to be welded. A zipper tape is bonded to the edge of one surface of each piece 50. The zipper tape and the zipper pull 51 engage to pre-position the weld seam of the piece 50 to be welded. The welding device includes a frame 1, which includes a frame base and a frame beam for supporting various components of the welding device. Each component includes: a welding actuator 4 and a welding table 7 located below the welding actuator 4; a feeding mechanism located at one end of the welding table 7 and a driving mechanism 3 located at the other end of the welding table 7; a zipper pull holder 5 mounted on the frame 1 for fixing the zipper pull 51; a zipper tape groove 6 for accommodating the zipper tape teeth after engagement; and a zipper tape removal mechanism 53 located below the outlet of the zipper tape groove 6 for separating and removing the heated zipper tape from the weld seam surface.

[0050] It should be noted that the zipper pull clamp 5 in this embodiment is preferably located near the starting end of the zipper tape groove 6. It is a tool for clamping the zipper pull. It can be designed as a hook structure or a spiral clamp structure with clamping force according to the actual situation to fix and clamp the zipper pull. The clamping function is achieved by hooking the zipper pull. This design structure is simple, easy to operate and quickly fix the zipper pull.

[0051] The frame 1 comprises three parts: a frame beam, a frame base, and frame columns. The frame beam is located on the upper part of the frame and, from left to right, is equipped with a feeding mechanism, a control box 8, and a welding execution mechanism 4. The frame beam is made of a high-strength, rigid alloy material, which can effectively resist the impact force during the welding of the capsule body pieces and ensure the quality of the weld. The frame base is located at the bottom of the device and is used to support the normal operation of the device and improve the stability of the equipment. From left to right, the upper surface of the frame base is equipped with a guide platform 60, a first roller group 63, a second roller group 64, and a drive mechanism 3. The frame base is made of a thick metal plate or a rigid frame with good rigidity, and has good pressure resistance and impact resistance, which can withstand the welding pressure and impact force during the welding of the airship capsule body pieces. Casters are installed on the lower surface of the frame base for moving the equipment. The frame columns connect the frame beam and the frame base, and a welding strip feeding tray 21 and a welding strip limiter 22 are fixedly installed on the side of the frame columns.

[0052] The spacing of the zipper groove 6 is adjusted according to the width of the zipper teeth after zipping. The adjustment range is 4mm to 10mm. For example, for zipper #3, the groove spacing is set to 4.0mm to 4.5mm.

[0053] The flexible material in this embodiment is a material with properties such as bendability and foldability, such as plastic film, rubber, flexible circuit board, and airship capsule; the following utilizes the technical solution of the welding equipment in this embodiment, combined with Figure 1 , Figure 3 , Figure 5 As shown, the working principle of welding the flexible material of the airship's capsule is as follows:

[0054] First, a zipper tape is glued to the surface edge of the cut piece to be welded (bag body cut piece). Two adjacent cut pieces 50 to be welded are pulled together from the starting end by a length of 0.3m to 1.5m through the cooperation of the zipper pull and the zipper tape. At this time, the zipper pull 51 is fixed on the puller clamp 5. The pulled zipper tape is placed in the zipper tape groove 6 to achieve quick alignment and positioning of the weld seam area of ​​the bag body cut piece. The starting end of the pulled zipper tape extends to the drive wheel of the drive mechanism 3 through the zipper tape removal mechanism 53. At the same time, the bag body cut piece is placed on the welding table 7. At this time, the welding tape 20 is taken out from the welding tape feeding mechanism and guided and installed on the weld seam, and extends to the drive wheel 31 of the drive mechanism 3.

[0055] Then, control the welding actuator 4 to make the second actuator 42 move downward, and the driven wheel 32 and the driving wheel 31 make pressure contact, pressing the closed capsule piece starting section, welding strip and separated zipper firmly between the driven wheel 32 and the driving wheel 31, and move to the left under the drive of the drive mechanism 3.

[0056] Secondly, the heater 411 is controlled to heat up and reach the set temperature parameters; the first actuator 41 is controlled to move downward, and at the same time the drive wheel 31 of the drive mechanism 3 rotates. The bag body piece moves to the left under the drive mechanism. The zipper pull pulls the zipper tape of the two adjacent pieces to be welded together. The bag body piece and the welding tape enter the heater 411 at the same time and form a weld by hot pressing. The weld enters the cooler 412 for cold pressing and shaping. At the same time, the heated zipper tape is separated from the bag body piece by the zipper separation roller of the zipper tape removal mechanism 53. Under the drive of the drive mechanism 3, it moves to the left and enters the collection box.

[0057] Finally, the above welding process continued, achieving rapid and accurate positioning, stable and reliable welding of the capsule piece with a single-sided zipper, and simultaneously removing the zipper tape, resulting in a high-precision, high-quality weld that meets the high-efficiency and high-quality processing requirements of large airship capsules.

[0058] As a preferred implementation method, such as Figure 3 As shown, the welding equipment is divided into a positioning preparation area A, a welding heat sealing area B, a cooling and shaping separation area C, and a power area D along the material conveying direction. The feeding mechanism and the zipper head holder 5 are located in the positioning preparation area A to realize material feeding and rapid positioning. The zipper tape removal mechanism 53 and the cooler 412 are located in the cooling and shaping separation area C to realize weld cooling and shaping and separation of the zipper tape from the welding piece. The drive mechanism 3 is located in the power area D to realize power operation during the processing.

[0059] like Figure 2 As shown, the drive mechanism 3 includes a drive motor 30, a drive wheel 31, and a driven wheel 32 located above the drive wheel 31. The driven wheel 32 is linked to the welding execution mechanism 4 through an elastic component. The welding execution mechanism moves downward, causing the driven wheel 32 to come into pressure contact with the drive wheel 31.

[0060] It should be noted that the driving wheel 31 is a rubber wheel driven by a motor, and is mounted collinearly on the frame base with the second roller group 64 below the cooler 412 and the first roller group 63 below the heater 411. The driven wheel 32 is a rubber wheel or a toothed steel wheel, mounted directly above the driving wheel 31. By controlling the rapid upward and downward movement of the second actuator, the driven wheel 32 can quickly separate from and make pressure contact with the driving wheel 31. The elastic component has a buffering and suppressing effect for transmitting vertical loads, such as a coil spring or a gas spring.

[0061] Furthermore, such as Figure 1 , Figure 2 and Figure 3As shown, the welding actuator 4 includes a heater 411 located in the welding heat sealing zone B and a cooler 412 located in the cooling and shaping separation zone C. The heater 411 is located above the zipper belt groove 6, and the cooler 412 is located between the heater 411 and the driven wheel 32. A thermal isolation structure is provided between the heater 411 and the cooler 412 to isolate the heater from the influence of the cooler.

[0062] It should be noted that the thermal insulation structure is preferably, but not limited to, a thermal insulation component made of low thermal conductivity materials, such as a thermal insulation component made of glass wool or polyurethane foam with good thermal insulation performance; it can also be a reflective panel made of high reflectivity materials, such as a high reflectivity panel with aluminum foil laid on one side; and it can further be a composite thermal insulation panel made of multiple layers of materials such as ceramic fiber, metal foil and thermal insulation foam.

[0063] The cooler 412 is a metal block with good thermal conductivity, which is located to the left of the heater 411. The lower surface of the cooler is flat and smooth, and it is installed on the same plane as the heater 411 below the first actuator 41. By controlling the up and down movement of the first actuator 41, the contact and separation of the heater 411, the cooler 412 and the weld seam of the bladder body piece can be realized.

[0064] like Figures 1-4 As shown, the zipper tape groove 6 includes a first groove 61 located in the positioning preparation area A and a second groove 62 located in the welding heat sealing area B. The center line of the length of the first groove 61 is collinear with the center line of the length of the second groove 62. The welding equipment also includes a first roller group 63 located in the welding heat sealing area B and a second roller group 64 located in the cooling and shaping separation area C. Each roller in the first roller group 63 has a radial annular groove 620 formed at the axial center of each roller. The welding equipment also includes a guide platform 60 mounted on the frame, on which the first groove 61 is formed.

[0065] It should be noted that the first roller group 63 is preferably composed of silicone rollers arranged closely in sequence. Radial annular grooves 620 are formed on the rubber rollers, and each of the radial annular grooves 620 forms a collinear second sliding groove 62, which facilitates the forward movement of the bag material while accommodating the zipper tape. The width and depth of the radial annular groove 620 match the width and thickness of the zipper tape teeth. During the processing of the bag material weld, the heater presses the welding strip and the bag material onto the first roller group 63. The zipper tape teeth located on the lower surface of the bag material are confined within the radial annular grooves 620 of the first roller group 63, achieving a smooth upper surface of the bag material weld that can evenly withstand the heat and pressure of the heater, thereby obtaining a uniform and reliable weld.

[0066] The second roller group 64 is preferably an idler roller that acts as an intermediate transition. It is located directly below the cooler 412 and above the zipper tape removal mechanism 53. When the first actuator 41 moves downward, the cooler 412 contacts the idler roller, which generates a cooling and pressurizing effect on the weld seam of the bladder piece located therebetween, thereby achieving rapid cooling and shaping of the weld seam after high-temperature fusion. The idler roller is a smooth silicone roller with a width slightly larger than the width of the weld seam area of ​​the bladder piece.

[0067] Furthermore, the center of the radial annular groove 620 of the first roller group 63 is collinear with the center of the first slide groove 61 of the guide platform, and they have the same width. During the processing of the bladder body piece weld, the zipper teeth, after being pulled together on the lower surface of the weld, can smoothly pass through the radial annular groove 620 and be confined within the groove. The depth of the radial annular groove 620 is equal to or slightly greater than the thickness of the zipper teeth. During the processing of the bladder body piece weld, the weld area above the first roller group 63 remains planar, obtaining a uniform heating and pressure zone, avoiding defects such as incomplete welding or inability to weld due to uneven surface of the bladder body piece weld area.

[0068] To improve the cooling and shaping efficiency of the cooler 412 for the weld, a high-pressure airflow channel is provided inside the cooler 412, and a nozzle is also provided on the left side of the cooler. High-speed airflow is formed by compressed air, which on the one hand removes the heat inside the cooler to avoid excessive temperature rise in the cooler, and on the other hand blows the bag body cut piece and weld surface through the nozzle to accelerate the dissipation of heat from the surface of the flexible material and enhance the weld shaping effect.

[0069] The heater 411 includes a metal block with good thermal conductivity and a heating element and temperature sensor disposed within the metal block. Its lower surface is flat and has good thermal conductivity. During the welding process of the capsule body, the lower surface of the heater contacts the weld seam of the capsule body, which can quickly heat the welding strip and the weld seam area of ​​the capsule body, so that the two are fused and firmly welded.

[0070] Furthermore, such as Figure 3 As shown, the zipper tape removal mechanism 53 includes at least one zipper separating roller 531 and a bracket for mounting each zipper separating roller 531. The bracket is fixed on the frame 1. The zipper separating roller 531 is located below the second roller group 64. The zipper tape separated from the outlet of the zipper tape groove 6 passes through each zipper separating roller 531 and enters the drive mechanism at the other end of the welding table. Under the drive of the drive mechanism, the zipper tape is removed from the weld surface.

[0071] It should be noted that the zipper separating roller 531 is preferably not limited to a set of smooth steel wheels. The zipper separating roller 531 is located on the left side of the heater 411 and below the second roller group 64. During the welding process of the capsule body piece, the weld material of the capsule body piece coming out of the heater 411 is separated into two directions by the zipper separating roller 531. One direction is that the weld seam formed by the welding strip and the capsule body piece passes through the cooler 412 and reaches the drive mechanism. The other direction is that the heated zipper strip passes through the zipper separating roller 531 and reaches the drive mechanism. Under the pulling force of the drive mechanism, the zipper strip is removed from the weld seam surface at high temperature.

[0072] Furthermore, the rotational speed of the zipper separating roller is matched with the speed of the drive mechanism. This means that since the diameters of the drive wheel and the zipper separating roller may be different, their rotational speeds may also be different. Therefore, the rotational speed of the zipper separating roller and the speed of the drive mechanism must achieve a suitable proportional match to ensure that the equipment operates efficiently and stably, guaranteeing a smooth separation and conveying process of the zipper belt, and improving work efficiency and accuracy.

[0073] like Figure 1 As shown, the feeding mechanism includes a welding strip feeding mechanism 2, which includes a welding strip feeding tray 21 and a limiter 22 for guiding the welding strip 20. The limiter includes a first limiter 221 and a second limiter 222. The center plane of the receiving groove of the first limiter 221 and the second limiter 222 is in the same vertical plane as the center plane of the first slide groove 61 and the second slide groove 62. After being guided by the limiter 22, the welding strip 20 moves synchronously with the pulled-open zipper strip along the zipper strip slide groove 6. The center positioning of the weld is achieved by the limiting effect of the zipper strip teeth in the zipper strip slide groove 6.

[0074] It should be noted that the welding strip feed tray 21 is an I-beam structure made of lightweight rigid material, installed on the upper right side of the frame column, and is used to store the welding strip 20 for welding the bladder body pieces.

[0075] like Figure 6 As shown, the first limiter 221 is located below the welding strip feed tray 21 and is used for guiding and limiting the welding strip. It adopts a cylindrical structure with an adjustable angle and has a through-hole material receiving groove in the center of the cylinder. The lateral dimension of the material receiving groove is equal to or slightly larger than the width of the welding strip, such as the width of the material receiving groove being 0.5mm to 1mm wider than the width of the welding strip.

[0076] The welding strip, fed from the welding strip feed tray, passes through the receiving groove of the first limiter 221 and enters the second limiter 222, achieving accurate feeding of the welding strip. The second limiter 222 is positioned above the guide platform 60, on the bracket to the right of the heater 411. The limiting groove of the second limiter 222 is the same width as the receiving groove of the first limiter 221, and the center lines of the limiting groove of the second limiter 222, the receiving groove of the first limiter 221, and the first and second slide grooves 61 and 62 are all on the same plane, further ensuring the welding accuracy of the flexible material. During the welding process of the flexible material, the first limiter 221 and the second limiter 222 ensure that the welding strip is accurately guided below the heater, improving the positioning accuracy of the welding strip during the welding process.

[0077] As another implementation, the first limiter 221 can also be other slit structures used for strip limiting, such as... Figure 7 As shown, the first limiter 221 is composed of parallel rollers fixed by a rigid bracket. The gap between the two rollers or the roller diameter can be adjusted to better meet the feeding requirements of the welding strip.

[0078] Example 2

[0079] Combination Figure 1 As shown, this application provides a flexible material welding system, including the flexible material welding equipment and control system described in Embodiment 1 above. The control system includes a control device 8 for coordinating welding parameters with the zipper tape removal rhythm, such as adjusting the working temperature of the heater 411, the working pressure of the actuator 4, and the rotational speed of the drive mechanism 3, to ensure that the entire production or operation process can proceed smoothly and efficiently. The specific coordination control logic is preferably not limited to the following methods:

[0080] First, welding parameters and the speed and position of the zipper tape removal can be collected in real time through various corresponding sensors to accurately grasp the rhythm of the welding process;

[0081] Furthermore, the welding parameters and zipper tape removal data collected by the monitoring are transmitted to the processor of the control system. The processor compares and analyzes the collected data with the preset standard parameters and rhythm, calculates the deviation between the actual data and the standard data, and judges whether the current welding parameters and zipper tape removal rhythm match.

[0082] Then, based on the analysis results, the welding parameters are automatically adjusted by the control device; for example, when the zipper tape removal speed or the drive mechanism speed increases, the heater temperature can be appropriately increased and the working pressure of the welding actuator can be increased to ensure the welding quality; conversely, the corresponding parameters are reduced.

[0083] Throughout the welding and zipper tape removal process, the control system continuously monitors, analyzes, and adjusts, forming a closed-loop control cycle. This continuously optimizes the coordination between welding parameters and the zipper tape removal rhythm to ensure the stability and consistency of welding quality.

[0084] Example 3

[0085] like Figure 8 As shown, another aspect of this application provides a flexible material welding method, which is applied to the flexible material welding equipment described in any one of the above embodiments, and specifically includes the following steps:

[0086] Step S1: Fix the pull tab of the zipper pull 51 to the zipper pull holder 5, so that the adjacent cut pieces 50 to be welded with the zipper tape adhered to the surface edge are placed on the welding table 7. By pulling the zipper pull 51 and the zipper tape 52 together, the pulled zipper tape 52 is placed in the zipper tape groove 6, thereby realizing the weld seam positioning of the cut pieces 50 to be welded on the welding equipment; the end of the pulled zipper tape 52 enters the zipper tape removal mechanism 53 and extends to the drive mechanism 3;

[0087] Step S2: Place the welding strip 20 on the feeding mechanism 10 at one end of the welding table 7 onto the weld and extend it to the drive mechanism 3 at the other end of the welding table 7.

[0088] Step S3: Start the welding execution mechanism 4 and drive mechanism 3 so that the two adjacent pieces 50 to be welded are welded together by the welding strip 20. Under the drive of the drive mechanism 3, the welded flexible material moves toward the drive mechanism 3. The heated zipper strip 52 is separated by the zipper strip removal mechanism 53 and then moves toward the drive mechanism 3.

[0089] Furthermore, during the zipper tape removal process, the rotational speed of the zipper separating roller is matched with the speed of the drive mechanism.

[0090] The alignment of the welding strip with the weld seam is achieved in the following way:

[0091] After being guided by the limiter 22, the welding strip 20 moves synchronously with the pulled-closed zipper strip along the zipper strip groove 6, and the center of the weld is positioned by the limiting effect of the zipper strip teeth in the zipper strip groove 6.

[0092] Specifically, the welding method of this application embodiment is applied to a welding equipment for welding flexible materials of an airship capsule, and its working principle is described below:

[0093] Combination Figure 1 , Figure 2As shown, firstly, a zipper tape is glued to the surface edge of the cut piece to be welded (bag body cut piece). After two adjacent cut pieces 50 to be welded are pulled together from the starting end by a length of 0.3m to 1.5m through the cooperation of the zipper pull and the zipper tape, the zipper pull 51 is fixed on the puller clamp 5. The pulled zipper tape is placed in the zipper tape groove 6 to achieve rapid alignment and positioning of the weld seam area of ​​the bag body cut piece. The starting end of the pulled zipper tape extends to the drive wheel of the drive mechanism 3 through the zipper tape removal mechanism 53. At the same time, the bag body cut piece is placed on the welding table 7. At this time, the welding tape 20 is taken out from the welding tape feeding mechanism 10 and guided and installed on the weld seam, and extends to the drive wheel 31 of the drive mechanism 3.

[0094] Then, control the welding actuator 4 to make the second actuator 42 move downward, and the driven wheel 32 and the driving wheel 31 make pressure contact, pressing the closed capsule piece starting section, welding strip and separated zipper firmly between the driven wheel 32 and the driving wheel 31, and move to the left under the drive of the drive mechanism 3.

[0095] Secondly, the heater 411 is controlled to heat up and reach the set temperature parameters; the first actuator 41 is controlled to move downward, and at the same time the drive wheel 31 of the drive mechanism 3 rotates. The bag body piece moves to the left under the drive mechanism. The zipper pull pulls the zipper tape of the two adjacent pieces to be welded together. The bag body piece and the welding tape enter the heater 411 at the same time and form a weld by hot pressing. The weld enters the cooler 412 for cold pressing and shaping. At the same time, the heated zipper tape is separated from the bag body piece by the zipper separation roller of the zipper tape removal mechanism 53. Under the drive of the drive mechanism 3, it moves to the left and enters the collection box.

[0096] Finally, the above welding process continued, achieving rapid and accurate positioning, stable and reliable welding of the capsule piece with a single-sided zipper, and simultaneously removing the zipper tape, resulting in a high-precision, high-quality weld that meets the high-efficiency and high-quality processing requirements of large airship capsules.

[0097] Example 4

[0098] This application provides a flexible material welding process, including the flexible material welding method described in Embodiment 3 above. The welding process further includes pre-positioning the weld seam of the cut piece 50 by pulling and closing a zipper before welding. Specifically, a zipper tape is adhered to the edge of one surface of the cut piece 50 to be welded, and the zipper tape and zipper pull 51 are used to pre-position the weld seam of the cut piece 50. Then, during the welding process, the welding tape alignment and zipper tape removal are simultaneously completed by the limiter 22 of the welding tape 20, the zipper tape groove 6, and the zipper tape removal mechanism 53; continuous weld seam formation is achieved by combining a welding execution mechanism 4 with a heater 411, a cooler 412, and a drive mechanism 3.
