Description

Technical Field

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

[0002] Air mattresses use airbags as internal support or massage layers. These airbags consist 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 and deflating the airbag cavities to provide massage or elastic support. Currently, the nozzles connected to one end of the airbag are installed using a welding process. During welding, the nozzle is placed on a welding position at the end of the airbag, which is an extension of the end of the airbag. The nozzle, along with the end of the airbag at the welding position, is placed on a welding platform. During welding, the welding nozzle moves close to the welding platform and welds it to one end of the airbag. However, this method of manual welding results in low efficiency, as only one nozzle can be welded at a time. Furthermore, the manual operation of the welding nozzle near the welding platform leads to poor consistency in the fit between the nozzle and the platform, resulting in inconsistent welding quality. Utility Model Content

[0003] To address the technical problems of low efficiency and poor welding quality stability caused by manual welding assembly of air nozzles on existing airbag belts, this utility model provides an air nozzle welding machine. The air nozzle welding machine can weld and process multiple air nozzles at the same time, significantly improving processing efficiency. Moreover, the cooperation between the welding nozzle and the welding station is driven by electric equipment, resulting in good consistency between the welding nozzle and the welding station and stable welding quality.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: A gas nozzle welding machine includes a welding machine equipped with welding nozzles and a welding table equipped with welding stations. The welding machine is characterized by having multiple welding nozzles arranged in a straight line on a horizontal plane, each welding nozzle being mounted on the same welding nozzle mounting seat. The welding machine is equipped with a drive mechanism to drive the welding nozzle mounting seat to move up and down. The welding table is equipped with multiple welding stations arranged in a straight line on a horizontal plane, the arrangement direction of the welding stations being parallel to the arrangement direction of the welding nozzles, and the adjacent spacing of the welding stations being the same as the adjacent spacing of the welding nozzles. The welding table is driven by the drive mechanism to move horizontally on a frame. When welding gas nozzles, the welding table moves horizontally to below the welding nozzle mounting seat, and the welding nozzle mounting seat descends to allow the welding nozzles to cooperate with the welding table to perform welding operations. This invention increases the number of gas nozzles that can be welded in one operation by matching multiple welding nozzles with multiple welding stations, thereby improving the production efficiency of gas nozzle welding. The spacing between adjacent welding stations matches the spacing between adjacent welding nozzles, allowing multiple welding stations to align with multiple welding nozzles above. During welding, the welding station is precisely moved to below the welding nozzle mounting base by a drive mechanism, so that the welding nozzles and welding stations can be aligned vertically. At the same time, the welding nozzle mounting base is raised and lowered by a drive mechanism, causing each welding nozzle to coordinate with the welding station below. Compared with the existing manual operation of welding nozzles to match welding stations, the matching consistency between welding nozzles and welding stations is better, and the quality of gas nozzle welding is more stable. After welding is completed, the welding nozzle mounting base rises to separate the welding nozzles from the welding station.

[0005] As a further improvement and supplement to the above technical solution, this utility model adopts the following technical measures: the number of welding stations arranged in a straight line along the welding platform is greater than the number of welding nozzles. Increasing the number of welding stations allows for the pre-installation of more air nozzles and air bag belts on the welding platform. During processing, the welding platform moves horizontally, allowing each welding station to have the opportunity to move horizontally to the bottom of the welding nozzle mounting seat and align with the welding nozzle. Each welding station can cooperate with the welding nozzle in sequence to perform welding operations, further improving the output and production efficiency of air nozzle welding.

[0006] The frame has a welding table at each end, and two independent drive mechanisms drive the two welding tables to alternately move to the middle section of the frame. The welding machine is located on the side of the middle section of the frame, and the welding nozzle mounting base is located above the middle section of the frame. The two welding tables on the frame are driven by independent drive mechanisms to alternately move to the middle section of the frame, taking turns to cooperate with the welding nozzle on the welding machine to weld the air nozzles on the welding table. When one welding table moves to the middle section of the frame to weld the air nozzle, the other welding table moves back to the end of the frame to unload and remove the already welded air bag strip or load and replace it with the air bag strip and air nozzle to be processed. In this way, the two welding tables work alternately, taking turns to weld the air nozzle and load and unload the air nozzle, saving processing time and improving the production efficiency of air nozzle welding. Moreover, the loading and unloading operations of the welding tables are all carried out at the end of the frame, which is not affected by the welding machine, greatly facilitating the operation of the workers.

[0007] The drive mechanism on the frame includes a motor and a transmission pair driven by it. The transmission pair is connected to the corresponding welding table, and the frame is equipped with a common slide rail matching the two welding tables. Each welding table is driven by a drive mechanism consisting of a motor and a transmission pair, moving horizontally along the shared slide rail. Since the two welding tables are located at opposite ends of the frame and move alternately towards the middle, only the common slide rail on the frame is needed to accommodate both welding tables, allowing them to alternately move to the middle of the frame for welding operations. In practical use, the transmission pair can be a common belt drive or a sprocket drive.

[0008] The transmission pair is a belt drive pair, and the welding table is fixedly connected to the belt of the corresponding belt drive pair via a moving block. Belt drive pairs have low manufacturing and maintenance costs, are sufficient to meet the low-speed translational movement requirements of the welding table, and operate quietly, while also providing shock absorption and vibration damping. In use, the moving block consists of two separate upper and lower parts that clamp and fix the belt to it. The welding table is fixed to one of these separate parts, thus connecting the welding table and the belt. The movement of the belt drives the welding table to move. As shown in the figure, in this embodiment, the welding table is preferably fixedly connected to the upper separate part.

[0009] A conductive block is installed on the frame below the welding nozzle. When the welding table moves to the middle section of the frame, the conductive block contacts the welding table, and the welding nozzle mounting base is connected to an elastic conductive sheet that supplies power. Both the welding table and the welding nozzle mounting base need to be energized during welding operations. The conductive block is designed to improve the safety of energized welding operations. The welding table, welding nozzle mounting base, and welding nozzle are all made of metal. When the welding table moves to the middle section of the frame and contacts the conductive block, the welding table and the welding nozzle on it are energized for welding operations. When the welding table is at the end of the frame, it is away from the conductive block and is de-energized. Workers can safely load and unload materials from the welding table at both ends of the frame. The welding nozzle mounting base is powered through a connected elastic conductive sheet. The conductive sheet is a thin, elastic sheet with high deformation performance to meet the high-frequency voltage required by the welding nozzle during welding operations. During welding operations, the conductive block and the elastic conductive sheet are energized.

[0010] The welding platform is equipped with multiple airbag mounting positions arranged in a straight line on a horizontal plane, each corresponding to a specific airbag mounting position on the welding platform. By placing the airbag closest to the nozzle on the airbag strap at the airbag mounting position, the placement of the airbag strap is limited, allowing the end of the airbag strap and the nozzle to be accurately positioned on the welding platform, facilitating the welding and fixing of the nozzle.

[0011] The welding platform is provided with several positioning blocks arranged in a straight line on a horizontal plane. The arrangement direction of the positioning blocks is parallel to the translation direction of the welding platform. The number of positioning blocks is the same as the number of welding platforms and they can be paired in pairs. Each welding platform has an airbag mounting position on the top surface of the paired positioning block. The number and position of the positioning blocks correspond to the welding platforms on the same welding platform. The positioning blocks and welding platforms are paired in pairs. Each positioning block has an airbag mounting position for placing the airbag body on the side of the paired positioning block, so that the ends of multiple airbags along with the air nozzles can be placed on the corresponding welding platform for welding operations.

[0012] The positioning block has a vertically positioned limiting post on the outer side of the airbag mounting position. The limiting post restricts the airbag strap when the airbag body is placed in the mounting position. The function of the limiting post is to limit the airbag body placed on the positioning block, preventing displacement of the airbag strap from affecting the welding and fixing of the nozzle. To facilitate the use of the limiting post, a dedicated positioning through hole is provided on the airbag strap for the limiting post to pass through.

[0013] The positioning block and the welding station are fixedly connected to the same mounting frame, which is detachably connected to the welding station. The welding station is equipped with a fixing frame with multiple parallel airbag placement slots. The number and position of the airbag placement slots match the positioning block. The positioning block and the welding station form a combination through their fixed connection with the mounting frame. Since the mounting frame and the welding station are detachably connected, if there is a problem with the positioning block and the welding station, the combination can be removed from the welding station and replaced with a spare combination of the positioning block, welding station, and mounting frame, reducing the impact of maintenance waiting on nozzle welding production. The airbag placement slots can accommodate and limit the remaining part of the airbag, further limiting the airbag and preventing it from shifting. The airbag is set on a dedicated fixing frame and is separate from the welding station. When the size and specifications of the airbag change, only the fixing frame with the matching airbag placement slots needs to be replaced, without replacing the entire welding station. The welding station is mounted on the frame and is inconvenient to disassemble.

[0014] The beneficial technical effects of this utility model are as follows: by matching multiple welding nozzles and multiple welding stations, the number of gas nozzles that can be welded in one operation is increased, thereby improving the production efficiency of gas nozzle welding; the spacing between adjacent welding stations matches the spacing between adjacent welding nozzles, allowing multiple welding stations to be aligned with multiple welding nozzles above; during welding operations, the welding station is precisely moved into position by a drive mechanism to align the welding nozzles and welding station vertically, and the welding nozzle mounting base is also raised and lowered by a drive mechanism, with each welding nozzle matching the welding station one by one, resulting in good consistency between the welding nozzles and welding stations and stable quality of gas nozzle welding processing; the welding station is only powered on when welding is performed in the designated area, and is powered off when leaving the designated area, making it safer to use.

[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 gas nozzle welding machine, including a welding machine 1 with welding nozzles 3 and a welding table 2 with welding stations 5. The welding machine 1 has multiple welding nozzles 3 arranged in a straight line on a horizontal plane, each welding nozzle 3 mounted on the same welding nozzle mounting base 4. The welding machine 1 has a drive mechanism that moves the welding nozzle mounting base 4 up and down. The welding table 2 has multiple welding stations 5 arranged in a straight line on a horizontal plane, with the arrangement direction of the welding stations 5 parallel to the arrangement direction of the welding nozzles 3. The spacing between adjacent welding stations 5 is the same as the spacing between adjacent welding nozzles 3. The welding table 2 is driven by the drive mechanism to move horizontally on a frame 6. During gas nozzle welding, the welding table 2 moves horizontally to below the welding nozzle mounting base 4, and the welding nozzle mounting base 4 lowers to allow the welding nozzles 3 to cooperate with the welding stations 5 for welding operations. The welding nozzle mounting base 4 can be moved up and down by a conventional cylinder drive device, which is existing technology. During welding, the nozzle 20 is placed at the welding position 21-2 at the end of the airbag belt 21. The end of the airbag belt, including the welding position, is placed on the welding station 5. The drive mechanism drives the welding station to move horizontally on the frame to below the nozzle mounting seat. Each nozzle and the welding station below are aligned. The nozzle mounting seat is lowered by the cylinder drive device. The nozzle and the corresponding welding station cooperate to fix the nozzle welding at the end of the airbag belt where the welding position is located.

[0027] This invention increases the number of gas nozzles produced in a single welding operation by increasing the number of welding nozzles and welding stations, and ensuring that they are matched one by one, thereby improving the production efficiency of gas nozzle welding. The spacing between adjacent welding stations matches the spacing between adjacent welding nozzles, allowing multiple welding stations to align with multiple welding nozzles above them. During welding, the welding station is precisely moved to the bottom of the welding nozzle mounting base via a drive mechanism, ensuring that the welding nozzles and welding stations are matched one by one and aligned vertically. At the same time, the welding nozzle mounting base is raised and lowered via a drive mechanism, causing each welding nozzle to descend and match the welding station below. Compared with manual welding, the matching consistency between the welding nozzles and welding stations is better, and the gas nozzle welding quality is more stable. After welding is completed, the welding nozzle mounting base rises to separate the welding nozzles and welding stations.

[0028] Preferably, the number of welding stations 5 arranged in a straight line on the welding station 2 is greater than the number of welding nozzles 3. More welding stations can be controlled to move and match the welding nozzles sequentially for welding operations, thereby improving welding output and processing efficiency.

[0029] Preferably, a welding table 2 is provided at each end of the frame 6. Two independent drive mechanisms are provided on the frame 6 to alternately move the two welding tables 2 to the middle section of the frame 6. The welding machine 1 is located on the side of the middle section of the frame 6, and the welding nozzle mounting seat 4 is located above the middle section of the frame 6. The drive mechanisms on the frame 6 include a motor 7 and its driven transmission pair. The transmission pair is connected to the corresponding welding table 2. The frame 6 is provided with a common slide rail 8 matching the two welding tables 2, such as... Figure 4The welding station 2 shown is mounted on a common slide rail 8 via six sliders 8-1. One of the welding stations has been removed from the figure to clearly show the common slide rail and the sliders. The transmission pair is a belt drive pair 9, and the welding station 2 is fixed to the belt of the corresponding belt drive pair 9 via a moving block 10.

[0030] Two welding tables on the frame are driven by independent belt drives, alternatingly moving to the middle section of the frame to work with the welding nozzles on the welding machine. The two welding tables work alternately, performing welding and loading / unloading operations, saving processing time and improving production efficiency. Loading and unloading operations are performed at the ends of the frame, unobstructed by the welding machine, facilitating worker operation. With the two welding tables located at opposite ends of the frame and moving alternately towards the center, only an extended set of common guide rails on the frame is needed to connect the two welding tables, allowing them to alternately move to the middle section of the frame for welding operations.

[0031] Preferably, a conductive block 11 is provided on the frame 6 below the welding nozzle 3. When the welding table 2 moves to the middle section of the frame 6, the conductive block 11 contacts the welding table 2. The welding nozzle mounting base 4 is connected to an elastic conductive sheet 12 that supplies power to it. During welding operations, the conductive block 11 contacts the welding table 2 to energize the welding table. The welding table, welding station, welding nozzle mounting base, and welding nozzle are all made of metal. During welding, both the welding table and the welding nozzle mounting base must be energized. The conductive block improves the safety of energized welding operations and ensures the safe use of the gas nozzle welding machine. During operation, when the welding table moves to the middle section of the frame and contacts the conductive block, the welding table and the welding station on it can be energized for welding operations. When the welding table is at the end of the frame and away from the conductive block, the welding table and the welding station are de-energized, and the worker can safely load and unload materials onto the welding station at both ends of the frame.

[0032] Preferably, the welding table 2 is provided with multiple airbag mounting positions 13 arranged in a straight line on the horizontal plane for placing the airbag body 21-1, and the airbag mounting positions 13 correspond one-to-one with the welding table 5; the welding table 2 is provided with a number of positioning blocks 14 arranged in a straight line on the horizontal plane, the arrangement direction of the positioning blocks 14 is parallel to the translation direction of the welding table 2, the number of positioning blocks 14 is the same as the number of welding tables 5 and they can be paired in pairs, and each welding table 5 has an airbag mounting position 13 on the side of the paired positioning block 14, and the top surface of each positioning block 14 is provided with an airbag mounting position 13. The positioning blocks 14 have two vertical limiting posts 15 on the outer side of the airbag mounting position 13, and the limiting posts 15 can limit the airbag strap 21 when the airbag body 21-1 is placed in the airbag mounting position 13.

[0033] In use, place the airbag body 21-1 closest to the nozzle on each airbag belt into the corresponding airbag mounting position to position each airbag belt, ensuring that the end of each airbag belt and the nozzle are accurately placed on the welding platform for easy welding and fixing of the nozzle. The limiting post further positions the airbag body placed on the positioning block, preventing airbag belt displacement from affecting nozzle welding and fixing. To accommodate the use of the limiting post, a dedicated positioning through hole is provided on the airbag belt for the limiting post to pass through. The positioning block 14 also has a notch 19 on each side of the airbag mounting position 13. The notch 19 is used to accommodate the extended edges of the airbag belt on the left and right sides. These extended edges are used for welding adjacent airbag belts together after overlap, allowing multiple adjacent airbag belts to be connected to form a single airbag pad.

[0034] Preferably, the positioning block 14 and the welding station 5 are fixedly connected to the same mounting frame 16. The mounting frame 16 is detachably connected to the welding station 2. The welding station 2 is provided with a fixing frame 17. The fixing frame 17 has multiple parallel airbag placement slots 18. The number and position of the airbag placement slots 18 match the positioning block 14.

[0035] When there is a problem with the positioning block and welding station, the assembly formed by the positioning block and welding station fixed together by the mounting bracket can be completely removed from the welding station and quickly replaced with a spare positioning block, welding station and mounting bracket assembly, which reduces the impact of delays in nozzle welding production caused by maintenance. The airbag belt placement slot is used to place the remaining part of the limiting airbag belt, further limiting the airbag belt to prevent it from shifting. The airbag belt is set on a special fixed frame and is separate from the welding station. When the size and specifications of the airbag belt change, only the fixed frame with the corresponding matching airbag belt placement slot needs to be replaced, without replacing the entire welding station. The welding station is moved and set on the frame, which is troublesome to disassemble and assemble.
