Description

Technical Field

[0001] This utility model relates to the field of airbag production equipment for mattresses, and in particular to a high-safety 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 is connected to an adjustable air pump via an air supply pipe to inflate and deflate the airbag cavities in a pre-set manner, providing massage or elastic support. The nozzle is welded to the end of the airbag using a nozzle welding machine. During welding, the nozzle is placed on a welding position at the end of the airbag, which is a receiving 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 processing, the nozzle is close to and cooperates with the welding platform, and both the nozzle and the welding platform are energized during the welding process. Existing nozzle welding machines lack effective protection for the energized nozzle and welding platform, posing a significant safety hazard of electric shock if someone approaches. Utility Model Content

[0003] To address the technical problem of existing gas nozzle welding machines lacking protection during operation due to the live welding nozzle and welding station, which easily leads to electric shock and safety accidents, this utility model provides a highly safe gas nozzle welding machine. The welding machine uses a protective structure to prevent workers from contacting the conductive welding nozzle and welding station, thus avoiding safety accidents caused by electric shock and effectively improving the safety of using the gas nozzle welding machine.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: A high-safety gas nozzle welding machine includes a frame, a welding host and a welding platform mounted on it, and a control box for controlling the welding host and the welding platform. The welding host is equipped with a lifting and movable welding nozzle, and the welding platform is equipped with a welding station that matches the welding nozzle. The welding nozzle and the welding station are conductive during welding operations. The key feature is that the gas nozzle welding machine includes an anti-electric shock protection structure with a baffle, which isolates the welding nozzle and welding station from the outside environment during welding operations. This utility model, through the anti-electric shock protection structure with a baffle, isolates the welding nozzle and welding station from the outside environment during welding operations, preventing personnel from contacting the electrified welding nozzle and welding station and causing electric shock and related safety accidents, thus improving the safety of the gas nozzle welding machine.

[0005] As a further improvement and supplement to the above technical solution, the present invention adopts the following technical measures: the frame is provided with a horizontal slide rail along its length, the welding host is located on the side of the middle section of the frame, the welding platform is movably located at one end of the horizontal slide rail and can move along the horizontal slide rail to below the welding nozzle, and the anti-electric shock protection structure is a barrier surrounding the horizontal slide rail and the welding host along the perimeter of the frame. The barrier consists of an openable and closable movable door and several baffles. The movable door is located on the side of the corresponding end of the horizontal slide rail. The welding platform is mounted on a horizontal slide rail on the frame and can move back and forth along the rail. A perimeter enclosure around the frame isolates the slide rail, welding platform, and welding machine from the outside environment. Whether the welding platform is at the end of the horizontal slide rail or under the welding nozzle, it is protected by the enclosure. The welding machine is also enclosed within the enclosure to prevent contact and accidents. When the welding platform moves back to the end of the horizontal slide rail, the worker can open the movable door to retrieve and place the airbag belt mounted on the welding platform. The airbag belt is placed on the welding platform along with its end set on the welding station. The baffle can also be made into a common movable sliding structure.

[0006] The opening length of the movable door matches the length of the welding platform, and both are parallel to the extension direction of the horizontal slide rail. The opening formed by the movable door, the extension direction of the welding platform, and the horizontal slide rail are all parallel and of similar size, used for loading and unloading the airbag straps. An opening that is too small will make loading and unloading inconvenient, while an opening that is too large will weaken the protective effect of the enclosure on the welding platform and the welding station on it.

[0007] The frame has a conductive block at its middle section. The welding platform moves along a horizontal slide rail to the middle section of the frame and contacts the conductive block. The welding nozzle is energized through a conductive spring. 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 and is energized when it moves along the horizontal slide rail to the middle section of the frame. Only then can the welding platform and the welding station be energized for welding operations. When the welding platform is at the end of the parallel slide rail, it is away from the conductive block, and the welding platform and welding station are de-energized. There is no risk of electric shock when operating on the welding platform. This prevents the safety hazards caused by the welding station being energized for a long time and reduces the energization time, thus reducing energy consumption. The welding nozzle is energized through a conductive spring. The conductive spring can be a thin elastic sheet with high deformation performance to meet the high-frequency voltage required by the welding nozzle during welding operations.

[0008] Each end of the horizontal slide rail is equipped with a welding platform, and the middle section of the frame corresponds to the middle section of the horizontal slide rail. Two independent drive mechanisms on the frame drive the two welding platforms to alternately move to the middle section of the horizontal slide rail. By setting a welding platform at each end of the horizontal slide rail, and having the two welding platforms alternately move to the middle section of the horizontal slide rail, they work in turn with the descending welding nozzle to perform welding operations, shortening the nozzle waiting time and improving the production efficiency of the gas nozzle welding machine. Each welding platform is driven by an independent drive mechanism for its translational movement, eliminating the need for a complex transmission mechanism to share power, resulting in better reliability and stability of the welding platform translation.

[0009] The control box is located in the middle of the frame via a movable robotic arm. The robotic arm can rotate in the horizontal plane, allowing the control box to be moved to the left or right sides of the welding host. The control box, which operates the welding host and welding table, can selectively move to the left or right side of the welding host by rotating the robotic arm in the horizontal plane. It controls the welding table at both ends of the horizontal slide rail to move below the welding nozzle and controls the welding nozzle to descend, coordinating the corresponding welding table and welding nozzle on the same side to complete the welding operation.

[0010] The welding host is equipped with multiple welding nozzles arranged in a straight line on a horizontal plane, each nozzle located at the bottom of the same nozzle mounting base. The welding host has a drive mechanism that moves the nozzle mounting base up and down. The welding platform is equipped with multiple welding stations arranged in a straight line on a horizontal plane, with the welding station arrangement direction and the welding nozzle arrangement direction located in the same vertical plane. The adjacent spacing of the welding stations is the same as the adjacent spacing of the welding nozzles. Matching more nozzles and welding stations increases the number of gas nozzles that can be welded in one operation, improving the gas nozzle welding efficiency. Matching the spacing between adjacent welding stations with the spacing between adjacent welding nozzles makes it possible for multiple nozzles to be simultaneously aligned with an equal number of welding stations. During welding, the welding platform moves horizontally below the nozzle mounting base, aligning the nozzles and welding stations one by one. The drive mechanism moves the nozzle mounting base and the nozzles at its bottom up and down, cooperating with the welding stations below the nozzles to perform the welding operation. The good matching consistency between the nozzles and welding stations ensures stable gas nozzle welding quality. After welding is completed, the drive mechanism raises the nozzle mounting base, separating the nozzles and welding stations.

[0011] The welding platform is provided with several positioning blocks parallel to the welding platform arrangement direction. The number of positioning blocks corresponds to the number of welding platforms and they are paired together. The welding platform is located on the side of the paired positioning block, and the top surface of the positioning block has a cavity for placing the airbag. 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 together, and the welding platform is located on the side of the paired positioning block. Each positioning block has a cavity for placing the airbag. Each airbag belt can place the airbag at the end of the adjacent air nozzle into the cavity of the positioning block to limit the airbag belt, thereby positioning the airbag belt so that its end is correctly limited on the welding platform for welding operations.

[0012] The positioning block has a vertically positioned limiting post on the outside of the cavity. The limiting post can limit the airbag strap when the airbag body is placed in the cavity. The limiting post can limit the airbag body placed on the positioning block to prevent the airbag strap from shifting and affecting the welding and fixing of the air nozzle. To cooperate with the limiting post, the airbag strap needs to be provided with a positioning through hole through which the limiting post passes.

[0013] The positioning block and welding station are detachably connected to the same mounting frame, which is detachably connected to the welding platform. The positioning block and welding station form a single unit through connection with the mounting frame. Because the mounting frame and welding platform are detachably connected, when the specifications of the gas bag to be welded change and the matching positioning block and welding station need to be replaced, the entire unit, including all three, can be removed from the welding platform for replacement. This reduces the time, effort, and inconvenience of disassembling each positioning station and welding station individually. The relative positions of the positioning block and welding station in each unit can be pre-adjusted on the mounting frame to ensure they work in sync. The welding station and positioning block are also detachably connected to the mounting frame, allowing for individual removal and replacement of damaged welding stations or positioning blocks, significantly reducing the subsequent operating costs of the gas nozzle welding machine.

[0014] The beneficial technical effects of this utility model are as follows: The anti-electric shock protection structure with baffles isolates the welding nozzle and welding station from the outside world during welding operations, preventing personnel from coming into contact with the electrified welding nozzle and welding station and causing electric shock, thus improving the safety of the gas nozzle welding machine; The addition of a conductive block on the frame and its contact with the welding station enables the switching on and off of power to the welding station. The welding station will only become energized when it moves to a specific position and contacts the conductive block, which not only prevents the safety hazards caused by the welding station being energized for a long time, but also reduces the energization time and energy consumption.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1-7 As shown, this utility model is a high-safety gas nozzle welding machine, including a frame 6 and a welding host 1 and a welding platform 2 mounted on it, as well as a control box 13 for controlling the welding host 1 and the welding platform 2. The welding host 1 is equipped with a lifting and movable welding nozzle 3, and the welding platform 2 is equipped with a welding station 5 that matches the welding nozzle 3. The welding nozzle 3 and the welding station 5 are conductive during welding operations. The frame 6 is equipped with a horizontal slide rail 8 along its length. The welding host 1 is located on the side of the middle section of the frame 6, and the welding platform 2 is movable at the end of the horizontal slide rail 8 and can move along the horizontal slide rail 8 to below the welding nozzle 3. The gas nozzle welding machine also includes an anti-electric shock protection structure with baffles 22. The anti-electric shock protection structure isolates the welding nozzle 3 and the welding station 5 from the outside world during welding operations. The anti-electric shock protection structure is a barrier that surrounds the horizontal slide rail 8 and the welding host 1 around the perimeter of the frame 6. The barrier consists of an openable and closable movable door 23 and several baffles 22. The movable door 23 is located on the side of the corresponding end of the horizontal slide rail 8. The opening length of the movable door 15 after opening matches the length of the welding station 2 and is parallel to the extension direction of the horizontal slide rail 8.

[0025] A protective enclosure consisting of baffles and a movable door isolates the energized welding nozzle and welding station from the outside environment during welding operations, preventing personnel from touching the nozzle and welding station and thus avoiding electric shock, thereby improving the safety of using the gas nozzle welding machine. The movable door can be opened for easy access to the airbag belt and nozzle.

[0026] To enhance safety, a conductive block 11 is installed in the middle section of the frame 6. The welding platform 2 moves along the horizontal slide rail 8 to the middle section of the frame 6 and contacts the conductive block 11. The welding nozzle 3 is energized through a conductive spring 12. Since the welding platform, welding station, and welding nozzle are all made of metal, they only come into contact with the conductive block and become energized when the welding platform moves along the horizontal slide rail to the middle section of the frame. At this time, the welding platform and the welding station on it are energized for welding operations. When the welding platform is at the end of the parallel slide rail, it is away from the conductive block, and the welding platform and welding station are de-energized. There is no risk of electric shock when operating on the welding platform. The welding nozzle is energized through a conductive spring made of an elastic sheet, which can meet the high-frequency voltage required by the welding nozzle during welding operations.

[0027] To improve the working efficiency of the gas nozzle welding machine and reduce the waiting time of the welding nozzle, a welding platform 2 is provided at each end of the horizontal slide rail 8. The middle section of the frame 6 corresponds to the middle section of the horizontal slide rail 8. Two independent drive mechanisms are provided on the frame 6 to alternately move the two welding platforms 2 to the middle section of the horizontal slide rail 8. Each drive mechanism includes a separate motor 7 and its driven transmission pair. The transmission pair is connected to the corresponding welding platform 2. In this embodiment, the transmission pair is preferably a belt drive pair. The welding platform 2 is fixedly connected to the belt of the belt drive pair 9 via a moving block 10. Figure 4 As 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 pass through the belt and clamp the belt. The welding platform 2 and the movable block 10 are fixedly connected. The movable block 10 can move synchronously with the belt, dragging the welding platform back and forth along the horizontal slide rail 8. In addition, the transmission pair can also be a chain drive pair.

[0028] Two welding platforms alternately move to the middle of the horizontal slide rail, working in turn with the descending welding nozzle to perform welding operations. This reduces the waiting time of the welding nozzle and improves the production efficiency of the gas nozzle welding machine. When one welding platform is performing welding operations, the other welding platform returns to the end of the horizontal slide rail, where the already welded air bag strip is removed or a new air bag strip and nozzle are loaded for welding. The two welding platforms cycle repeatedly, accelerating the production speed and improving the efficiency of the gas nozzle welding machine. Each welding platform is driven by an independent drive mechanism for its translational movement, eliminating the need for a complex transmission mechanism sharing power, effectively improving the reliability and stability of the welding platform's translation.

[0029] Furthermore, the control box 13 is positioned in the middle of the frame 6 via a movable robotic arm 24. The robotic arm 24 can rotate in the horizontal plane, allowing the control box 13 to be moved to the left or right sides of the welding host 1. The rotation of the robotic arm in the horizontal plane allows the control box, which operates the welding host and welding table, to be selectively moved to the left or right side of the welding host. This facilitates the manipulation of the welding tables at both ends of the horizontal slide rail to move below the welding nozzle and controls the descent of the welding nozzle, coordinating the corresponding welding table and welding nozzle on the same side to complete the welding operation. Figure 2 As shown, when the welding platform at the left end of the horizontal slide rail needs to be moved for welding operations, the robotic arm also rotates to the left and moves the control box to the same side of the welding host.

[0030] Furthermore, the welding host 1 is provided with multiple welding nozzles 3 arranged in a straight line on the horizontal plane. Each welding nozzle 3 is located at the bottom of the same welding nozzle mounting base 4. The welding host 1 is provided with a lifting mechanism to drive the welding nozzle mounting base 4 to move up and down. The welding platform 2 is provided with multiple welding stations 5 arranged in a straight line on the horizontal plane. The arrangement direction of the welding stations 5 and the arrangement direction of the welding nozzles 3 are located in the same vertical plane. The adjacent spacing of the welding stations 5 is the same as the adjacent spacing of the welding nozzles 3.

[0031] More welding nozzles and welding stations can be matched to increase the number of gas nozzles that can be welded in one go, thus improving the efficiency of gas nozzle welding. The spacing between welding stations and welding nozzles is matched to ensure that multiple welding nozzles are aligned and adapted to the welding station simultaneously. During welding, the welding station moves horizontally below the welding nozzle mounting base, aligning the welding nozzle and the welding station vertically. The drive mechanism drives the welding nozzle mounting base and the welding nozzle at its bottom to rise and fall, cooperating with the welding station below the welding nozzle to perform the welding operation. The matching consistency between the welding nozzle and the welding station is good, and the quality of gas nozzle welding is stable. After welding is completed, the drive mechanism drives the welding nozzle mounting base to rise, separating the welding nozzle and the welding station. The number of welding stations should ideally be an integer multiple of the number of welding nozzles. This allows for the placement of more nozzles and airbags to be welded at once on the welding station. During processing, the welding station is controlled to move along the horizontal slide rail, ensuring that each welding station has the opportunity to weld with the nozzle. Having several welding stations as many as the number of nozzles not only allows all welding stations to work in batches with the nozzles, but also avoids situations where individual welding stations repeatedly match nozzles or where some nozzles are left unused during welding operations, thereby increasing the output and processing efficiency of nozzle welding.

[0032] like Figure 5 and Figure 6 As shown, the welding platform 2 is provided with a number of positioning blocks 14 parallel to the arrangement direction of the welding stations 5. The number of positioning blocks 14 corresponds to the number of welding stations 5 and they are paired in pairs to form a group. The welding stations 5 are on the side of the paired positioning blocks 14. The top surface of the positioning block 14 is provided with a cavity 14-1 for placing the bladder 21-1. The positioning block 14 is provided with two vertically placed, symmetrically positioned limiting posts 15 on the outside of the cavity 14-1. The function of the limiting posts 15 is to limit the airbag band when the bladder is placed in the cavity 14-1.

[0033] like Figure 7 As shown, the positioning block 14 is also provided with grooves 25 and openings 19. Two grooves 25 are located on the front and rear sides of the positioning block 14 to accommodate the air tubes connecting to the airbag body on the airbag strap 21. The grooves 25 connect to the cavity 14-1. Two openings 19 are located on the left and right sides of the positioning block 14 to accommodate the connecting pieces extending from both sides of the airbag strap. The 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. Each positioning block 14 and welding station 5 can be detachably connected to the same mounting bracket 16, which is detachably connected to the welding platform 2. Detachable connection can be achieved using common screws or pins. The components through which the screws or pins are inserted must have pre-set matching mounting holes; this is existing technology.

[0034] The mounting bracket, welding station, and positioning block form a replaceable unit that can flexibly adapt to different specifications of airbag belts and nozzles. When the specifications of the airbag belt and nozzle change, simply replace the mounting bracket with a matching welding station and positioning block. This quick replacement improves the adaptability of the nozzle welding machine. The welding station and positioning block are pre-installed on the mounting bracket and do not need to be adjusted. The relative positions between the welding station and positioning block only need to be installed once for repeated use. The welding station and positioning block match well, and it also avoids the need to disassemble and replace the welding station and positioning block to match different specifications of airbag belts.

[0035] like Figure 5 As shown, to further position the airbag strap, the welding platform 2 is also equipped with multiple parallel airbag strap placement slots 18 and corresponding positioning blocks 14. The airbag strap placement slots 18 are located on the side of the positioning blocks 14 away from the welding station 5. All airbag strap placement slots 18 are located on the same fixing frame 17, which is detachably mounted on the welding platform 2. The airbag strap placement slots are used to place the remaining part of the airbag strap except for the ends and adjacent parts of the airbag, in order to position the airbag strap and prevent its displacement from affecting the welding operation. When the size and specifications of the airbag strap change, the fixing frame with the corresponding airbag strap placement slot can be replaced without replacing the entire welding platform. The welding platform is moved on a horizontal slide rail, making repeated disassembly and assembly inconvenient.
