Description

Technical Field

[0001] This utility model relates to the field of airbag production equipment for mattresses, and in particular to a highly adaptable air nozzle welding machine. Background Technology

[0002] Air mattresses use airbags as internal support or massage layers. Each airbag is composed of multiple airbags connected in a straight line. During operation, a sealed nozzle at one end of the airbag connects to an adjustable air pump via an air supply pipe, inflating or deflating the airbag cavities to provide massage or elastic support. Currently, the nozzle connected to one end of the airbag is assembled using a welding process. During welding, the nozzle is placed on a welding position at the end of the airbag, located in a cavity extending from the end of the airbag. The nozzle, along with the end of the airbag where the welding position is located, is placed on a welding platform. During welding, the welding nozzle approaches the welding platform and clamps the end of the airbag and the nozzle. Simultaneously, the welding nozzle and the welding platform are energized to weld and fix the nozzle to one end of the airbag. To position the airbag strap and prevent it from shifting relative to the welding station, thus affecting the welding quality, a strap positioning device is also set on the side of the welding station. Specifically, it is a concave cavity that can hold the airbag on the airbag strap. As long as the airbag closest to the end of the airbag strap is placed into the concave cavity, the concave cavity can limit the adjacent end of the airbag strap by cooperating with the airbag, thereby positioning the airbag strap. The existing welding station and bladder positioning device are all fixed on a welding platform. Once the welding of the airbag belt and nozzle changes, such as the diameter of the airbag belt and the specification of the nozzle, the original bladder positioning device and welding station will no longer be applicable and need to be replaced and rematched. If there are multiple welding stations and matching bladder positioning devices on the welding platform at the same time, the replacement is very troublesome. Whether it is replacing the welding station and bladder positioning device separately from the welding platform or replacing the entire welding platform with the new welding station and bladder positioning device, it is very time-consuming and labor-intensive. After the replacement, it is also necessary to ensure that the position of the welding station and bladder positioning device matches, and the position of the welding station matches the welding nozzle. If the position is incorrect, it will affect the subsequent welding operation between the welding nozzle and the welding station, resulting in poor welding effect of the nozzle and decreased welding quality stability. Utility Model Content

[0003] To address the technical problems of existing air nozzle welding machines where the welding station and air bag positioning device are directly mounted on the welding platform, making them inflexible in adapting to changes in air bag and air nozzle specifications, and requiring time-consuming and labor-intensive replacement of each welding station and air bag positioning device, as well as the need for recalibration after each replacement, this invention provides a highly adaptable air nozzle welding machine. This machine allows for flexible replacement of the welding station and air bag positioning device according to processing needs. Not only is the replacement of the welding station and air bag positioning device convenient, but the relative positions between the replaced welding station and air bag positioning device are accurate and require no calibration, effectively ensuring consistent welding results and stable welding quality. Furthermore, two movable welding platforms are used alternately with the welding nozzle for welding operations, shortening the waiting time for the welding nozzle and improving the production efficiency of the air nozzle welding machine. While one welding platform is welding, the other welding platform can perform loading and unloading operations. Loading involves placing new air bag strips and air nozzles to be welded, while unloading involves removing air bag strips with welded air nozzles.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: A highly adaptable gas nozzle welding machine includes a frame, on which welding platforms and a welding main unit are arranged vertically. The welding main unit has a lifting and movable welding nozzle. The welding platform has a welding station matching the welding nozzle and a bladder positioning device that engages with the welding station. The welding nozzle performs welding operations by lifting and cooperating with the welding station. The characteristic feature is that the welding platform has a detachable mounting frame, and the welding station and bladder positioning device are mounted on the mounting frame. This utility model places the welding station and bladder positioning device on a mounting frame that can be detachably connected to the welding platform. The mounting frame, welding station, and bladder positioning device form a whole, facilitating replacement and flexibly adapting to different specifications of air bladders and nozzles. When the specifications of the air bladder and nozzle change, the mounting frame with the corresponding welding station and bladder positioning device can be directly replaced, improving the adaptability of the gas nozzle welding machine. The specifications and positions of the welding station and bladder positioning device on the same mounting frame are fixed, eliminating the need for frequent adjustments and disassemblies, ensuring consistent welding results and stable welding quality.

[0005] As a further improvement and supplement to the above technical solution, this utility model adopts the following technical measures: the bladder positioning device is a positioning block provided on the mounting frame. The positioning block is on the side of the welding station, and its top surface has a cavity for matching the bladder. The bladder positioning device is a positioning block with a cavity on its top surface. The positioning block is also provided on the mounting frame and located on the side of the welding station. During operation, the positioning block accommodates the bladder closest to the end of the airbag belt through the cavity on its top surface, so that the airbag belt is limited on the welding station, preventing the airbag belt from shifting and affecting the welding process of the air nozzle.

[0006] The soldering station and positioning block are detachably connected to the mounting bracket. All connections between the soldering station / positioning block and the mounting component are detachable, preventing the need to replace the entire mounting bracket and remaining soldering stations / positioning blocks due to damage to individual soldering stations or positioning blocks. Problematic soldering stations or positioning blocks can be replaced individually, which is not only convenient but also reduces operating costs. The detachable connection can be achieved using common screws or pins, and the mounting bracket should have several pre-drilled matching mounting holes.

[0007] The positioning block has a vertically positioned limiting post on the outside of the cavity. The limiting post can be inserted through a positioning hole on the airbag belt to limit its position. The limiting post passing through the pre-drilled positioning hole on the airbag belt further limits the airbag belt, preventing it from shifting and affecting the welding of the air nozzle. To cooperate with the limiting post, a section extends from the side of the airbag belt and has a pre-drilled positioning hole to match the limiting post.

[0008] The welding host is equipped with a welding nozzle mounting base that is driven to move up and down via a drive mechanism. The bottom of the welding nozzle mounting base has multiple welding nozzles arranged in a straight line on a horizontal plane. The mounting frame has multiple welding stations arranged in a straight line on a horizontal plane and positioning blocks that match each welding station. The welding nozzles, welding stations, and positioning blocks are arranged in parallel directions, and the adjacent spacing between welding stations is the same as the adjacent spacing between welding nozzles. The arrangement of multiple welding nozzles, welding stations, and positioning blocks along parallel straight lines increases the number of gas nozzles that can be welded, improving the production efficiency of gas nozzle welding. The consistent adjacent spacing between welding stations and welding nozzles makes it possible to align and weld multiple welding stations and multiple welding nozzles.

[0009] The welding platform has multiple parallel airbag strap placement slots and corresponding positioning blocks. Each airbag strap placement slot is located on the side of the corresponding positioning block furthest from the welding platform, and all slots are located on the same mounting bracket, which is fixed to the welding platform. The function of the airbag strap placement slots is to accommodate the remaining portion of the airbag strap, excluding the welding end and the first airbag near the adjacent end, thus limiting the airbag strap's position and preventing it from shifting and affecting the welding of the air nozzle at the end of the airbag strap. During use, the mounting bracket with a suitable welding platform and positioning blocks can be replaced according to the airbag strap specifications, enabling quick switching and improving ease of use.

[0010] The welding platform is movably mounted on the machine frame, and the number of welding stations on the platform exceeds the number of welding nozzles. Increasing the number of welding stations allows for the placement of more nozzles and air bags on the platform at once. During processing, the welding platform moves back and forth, giving each welding station a chance to move under the nozzle and wait to cooperate with it for welding operations, thus welding more nozzles and improving production efficiency. In use, the number of welding stations can be set to an integer multiple of the number of welding nozzles. Each time the welding platform moves, a set of welding stations is positioned to match the nozzle, avoiding individual welding stations repeatedly matching nozzles or individual nozzles being idle during welding.

[0011] The frame is equipped with two welding platforms, and the welding stations on the two platforms can alternately cooperate with the welding nozzle to perform welding operations. During welding operations, the two welding platforms alternately move to the bottom of the welding main unit. Using two welding platforms to cooperate with the welding nozzle in turn can shorten the idle waiting time of the welding nozzle and improve the production efficiency of welding operations. During operation, the two welding platforms alternately move to the bottom of the welding main unit to complete the welding operation in conjunction with the lifting and lowering welding nozzle, or the two welding platforms are fixed, and the welding nozzle moves back and forth between the two welding platforms. After moving to the top of one welding platform, it moves up and down to complete the welding operation. After the operation is completed, the welding nozzle moves to the top of the other welding platform, and so on, with the welding nozzle repeatedly moving and rising and falling in cooperation with the welding stations on the two welding platforms.

[0012] The frame is equipped with a horizontal slide rail. The welding host is located above the middle section of the horizontal slide rail. The two welding platforms are located at both ends of the horizontal slide rail and are alternately moved to the middle section of the horizontal slide rail under the drive of an independent drive mechanism. The drive mechanism includes a motor and a transmission pair driven by it, and the transmission pair is connected to the corresponding welding platform. The two independent drive mechanisms can drive the two welding platforms to move along the horizontal slide rail respectively. During operation, the two welding platforms alternately move to the middle section of the horizontal slide rail to cooperate with the welding host above. The two drive mechanisms work independently, each driving one welding platform to move, which is reliable and stable. Each drive mechanism includes a separate motor and a matching transmission pair. The welding platform moves by connecting to the transmission pair.

[0013] A conductive block is installed on the frame below the welding host. When the welding platform moves to the middle section of the horizontal slide rail, it comes into contact with the conductive block. The welding nozzle is energized through an elastic conductive sheet. The purpose of the conductive block is to improve safety during energized welding operations. The welding platform, welding station, and welding nozzle are all made of metal. The welding platform only contacts the conductive block when it moves to the middle section of the horizontal slide rail, allowing energization for welding operations. When the welding platform is at the end of the parallel slide rail, away from the conductive block, the welding platform and welding station are de-energized, eliminating concerns about electric shock. The welding nozzle is energized through an elastic conductive sheet, which is a thin, highly deformable elastic sheet capable of meeting the high-frequency voltage requirements of the welding nozzle during welding operations.

[0014] The beneficial technical effects of this utility model are as follows: the welding station and the bladder positioning device are set on a mounting frame that can be detachably connected to the welding platform, so that the mounting frame, the welding station and the bladder positioning device are integrated into a whole for easy replacement and flexible adaptation to different specifications of airbag belts and nozzles; the specifications and positions of the welding station and the bladder positioning device on the mounting frame are fixed, eliminating the need for repeated disassembly and adjustment, further ensuring consistent welding effect and stable welding quality of the nozzles.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1-9As shown, this utility model is a highly adaptable gas nozzle welding machine, including a frame 6. The frame 6 has a welding platform 2 and a welding main unit 1 arranged vertically on it. The welding main unit 1 has a lifting and movable welding nozzle 3. The welding platform 2 has a welding station 5 that matches the welding nozzle 3 and a capsule positioning device that mates with the welding station 5. The welding nozzle 3 performs welding operations in conjunction with the welding station 5 through lifting and movable movement. The welding platform 2 has a detachable mounting frame 16. The welding station 5 and the capsule positioning device are both mounted on the mounting frame 16. In this embodiment, the capsule positioning device... The positioning device is a positioning block 14 on the mounting frame 16. The positioning block 14 is on the side of the welding station 5 and has a cavity 13 on the top surface that matches the air bag 21-1. During the welding operation, the end of the air bag 21 closest to the air nozzle is placed in the cavity 13 to position the air bag 21. The welding station 5 and the positioning block 14 are detachably connected to the mounting frame 16. The positioning block 14 has two symmetrical vertical limiting posts 15 on the outside of the cavity 13. The limiting posts 15 can limit the air bag by passing through the positioning holes on the air bag.

[0027] This invention integrates the welding station and the airbag positioning device onto a mounting frame that can be detachably connected to the welding platform. This allows the mounting frame, welding station, and airbag positioning device to form a replaceable unit, flexibly adapting to different specifications of airbag straps and nozzles. When the specifications of the airbag strap and nozzle change, simply replace the mounting frame with the matching welding station and airbag positioning device for quick replacement, improving the adaptability of the nozzle welding machine. Since the welding station and airbag positioning device are pre-installed on the mounting frame, no further adjustments are needed. The relative positions of the welding station and airbag positioning device only need to be adjusted once for repeated use, ensuring a good match between them and avoiding the positioning hassle of repeated disassembly and reassembly. Multiple mounting frames can be prepared in advance, each equipped with a welding station of a specific specification and a matching airbag positioning device. The appropriate mounting frame is then installed on the welding platform according to the specifications of the airbag strap and nozzle to be welded.

[0028] To ensure proper placement of the airbag strap and prevent displacement from affecting welding, the positioning block 14 is equipped with grooves 22 and notches 19. Two grooves 22 are located on the front and rear sides of the positioning block 14 to accommodate the air tubes connecting to the airbag on the airbag strap. The grooves 22 connect to the cavity where the airbag mounting position 13 is located. Two notches 19 are located on the left and right sides of the positioning block 14 to accommodate connecting pieces extending from both sides of the airbag strap. These connecting pieces are used to weld adjacent airbag straps together, allowing multiple adjacent airbag straps to be connected to form a single airbag pad. Before welding, the air nozzle 20 is placed at the welding position 21-2 at the end of the airbag strap 21. The entire end of the airbag strap 21 on the welding side, including the welding position, is placed on the welding station 5.

[0029] Furthermore, the welding host 1 is provided with a welding nozzle mounting base 4 that is driven to move up and down by a drive mechanism. The bottom of the welding nozzle mounting base 4 is provided with multiple welding nozzles 3 arranged in a straight line on the horizontal plane. The mounting frame 16 is provided with multiple welding stations 5 arranged in a straight line on the horizontal plane and positioning blocks 14 that match each welding station 5 one by one. The welding nozzles 3, welding stations 5 and positioning blocks 14 are arranged in parallel directions, and the adjacent spacing of welding stations 5 is the same as the adjacent spacing of welding nozzles 3. The welding platform 2 is also provided with multiple parallel airbag belt placement slots 18 and each positioning block 14 that matches one by one. The airbag belt placement slots 18 are on the side of the corresponding positioning block 14 away from the welding station 5. All airbag belt placement slots 18 are opened in the same fixed frame 17, which is set on the welding platform 2. The welding platform 2 is movably set on the frame 6. The number of welding stations 5 on the welding platform 2 is more than the number of welding nozzles 3. Preferably, the number of welding stations is an integer multiple of the number of welding nozzles.

[0030] Multiple welding nozzles, welding stations, and positioning blocks arranged in parallel along a straight line effectively increase the number of gas nozzles for welding, improving welding efficiency. The spacing between adjacent welding stations is the same as that between adjacent welding nozzles, allowing multiple welding stations and nozzles to be aligned and welded synchronously. All airbag mounting slots are located on the same fixed frame. These slots accommodate the remaining portion of the airbag strip, excluding the welding end and the first airbag near the adjacent end, limiting its position and preventing displacement that could affect the welding and installation of the gas nozzle at the end of the airbag strip. During use, the mounting slots can be wider to accommodate more airbag strips of various sizes. The mounting frame with appropriate welding stations and positioning blocks can be replaced according to the airbag strip specifications. More matching gas nozzles and welding stations improve production efficiency. When the number of welding stations is an integer multiple of the number of welding nozzles, each movement of the welding station ensures that one set of welding stations is in place to match an equal number of welding nozzles, preventing individual welding stations from repeatedly matching welding nozzles or individual welding nozzles from being left unattended during welding.

[0031] Furthermore, the frame 6 is equipped with two welding platforms 2. The welding stations 5 on the two welding platforms 2 can alternately cooperate with the welding nozzles 3 to perform welding operations. During welding operations, the two welding platforms 2 alternately move to below the welding host 1. To achieve the movable movement of the welding platforms, the frame 6 is equipped with a horizontal slide rail 8. The welding host 1 is located above the middle section of the horizontal slide rail 8, and the two welding platforms 2 are located at both ends of the horizontal slide rail 8. Figure 7 The welding platform 2 shown is mounted on the common slide rail 8 by means of six sliders 8-1. Figure 7 To clearly demonstrate the common parallel slide rail and six sliders, one welding platform was removed. Each of the two welding platforms 2 is driven by an independent set of drive mechanisms, alternately moving along the horizontal slide rail 8 to the middle section of the horizontal slide rail. Each drive mechanism includes a separate motor 7 and its driven transmission pair, which is connected to the corresponding welding platform 2. In this embodiment, the transmission pair is a belt drive pair, and the welding platform 2 is fixedly connected to the belt of the belt drive pair 9 via a moving block 10. Figure 6As shown, the welding platform 2 is fixedly connected to the belt of the belt drive pair 9 via the movable block 10. The movable block 10 has a slot to accommodate and clamp the belt of the belt drive pair, allowing the movable block to move synchronously with the belt. The welding platform 2 and the movable block 10 are fixedly connected, and the motor drives the belt to move, thus driving the welding platform to move along the horizontal slide rail. Alternatively, a chain drive pair can also be used as the transmission pair.

[0032] Two welding platforms are driven by independent mechanisms to alternately move to the middle position of the horizontal slide rail, cooperating with the welding nozzle that moves up and down with the nozzle mounting seat to complete the welding operation. When one welding platform is performing welding operations, the other welding platform remains at the end of the horizontal slide rail. The welding stations on the two welding platforms take turns matching the welding nozzle to perform welding operations, effectively shortening the waiting time of the welding nozzle and improving the production efficiency of the gas nozzle welding machine.

[0033] Furthermore, a conductive block 11 is also provided on the frame 6 below the welding host 1. When the welding platform 2 moves to the middle section of the horizontal slide rail 8, it comes into contact with the conductive block 11. The welding nozzle 3 is energized through an elastic conductive sheet 12. The conductive sheet 12 is fixed to the welding nozzle mounting seat 4 and energizes the welding nozzle through the welding nozzle mounting seat. The welding nozzle mounting seat 4, the welding nozzle 3, the conductive block 11, the welding platform 2, and the welding station 5 are all made of metal. When the welding platform moves to the middle section of the horizontal slide rail and contacts the conductive block, the welding platform and the welding station on it can be energized for welding operations. When the welding platform is at both ends of the horizontal slide rail, it is away from the conductive block, and the welding platform and the welding station are de-energized. This allows for safe operation without the risk of electric shock, thereby improving the safety of the gas nozzle welding machine.
