Abstract
Description
Technical Field
[0001] This invention relates to the field of machining technology, and in particular to a semi-automatic, high-efficiency welding device for sound-absorbing cotton panels. Background Technology
[0002] In ventilation engineering applications, ventilation ducts with internal sound-absorbing cotton are required in special locations such as subway tunnels. The sound-absorbing cotton needs to be pre-fixed to the surface of the duct panels. This is usually done by welding the cotton to the panels with nails that have round plates. However, the welding position must not affect the appearance and surface coating of the other side of the panel. Currently, this operation is done manually, one by one, which is inefficient. Moreover, the position of the nails and the quality of the welds are inconsistent during the welding process, affecting the appearance and quality of the ventilation duct. Summary of the Invention
[0003] To address the shortcomings of existing technologies, the present invention aims to provide a semi-automated, high-efficiency welding device for sound-absorbing cotton panels. By automating key processes, the device achieves standardized operations, improves work efficiency, and ensures product appearance and quality.
[0004] The technical solution adopted by this invention to solve its technical problem is:

[0006] The material storage and feeding system is used to transport nails one by one to the mobile platform. The mobile platform is slidably assembled on the equipment bracket along the welding operation direction, and the electrode working part on the mobile platform welds and fixes the nails to the ventilation duct plate of the base platform.
[0007] It also includes a switch handle for controlling the execution of welding actions, the switch handle being mounted on the mobile platform and positioned away from the mobile platform.
[0008] The electrode working section of the basic platform has a slender structure, and the surface of the electrode working section is covered with an electrode plate that is connected to the distribution box.
[0009] The electrode working part of the mobile platform adopts an electrode block structure, and a magnet is installed inside the electrode working part, with the magnet positioned close to the bottom surface of the electrode working part.
[0010] The electrode working part is mounted and fixed at the bottom of a linear drive mechanism and is vertically slidable.
[0011] The material storage and supply system includes a feeder, a conveying mechanism, and a feeding mechanism. The feeder, through its own action, conveys the nails one by one through the conveying mechanism to the feeding mechanism, which then feeds the nails into the lower part of the electrode working section for welding.
[0012] The feeder is a vibratory feeder, which is installed and fixed on the upper part of the equipment support.
[0013] The conveying mechanism includes a split-structure first conveying plate and a second conveying plate. The interior of the first conveying plate and the second conveying plate are respectively provided with a channel for the movement of the nail disc and a clearance channel for the movement of the nail.
[0014] The first conveyor plate is located at the top and is fixed on the equipment bracket. The top of the first conveyor plate is connected to the discharge port of the feeder, and the bottom of the first conveyor plate is sealed by an openable baffle.
[0015] The second conveyor plate is located at the bottom and is fixed on the moving platform. The bottom end of the second conveyor plate is connected to the feed inlet of the feeding mechanism. The top end of the second conveyor plate is correspondingly set to the bottom end of the first conveyor plate. The side of the second conveyor plate is provided with a lever for opening the baffle.
[0016] The feeding mechanism is installed and fixed on the mobile platform. The feeding mechanism includes a slider, a track and a linear drive mechanism. The linear drive mechanism and the track are respectively installed and fixed on the mobile platform. The slider is slidably disposed in the track. The outer end of the slider is connected to the drive rod of the linear drive mechanism to drive the slider to slide in the track. The inner end of the slider is provided with a discharge port, and the track is also provided with a feeding port communicating with the discharge port. When the slider slides to the working position, the discharge port is located directly below the electrode working part on the mobile platform.
[0017] The outer edge of the feed port of the slider is also provided with a limiting piece connected thereto. The limiting piece is rotatably connected to the slider and is in contact with the inner wall of the track and cannot be rotated.
[0018] The beneficial effects of this invention are: the structure is reasonably designed and the high-efficiency welding equipment can realize semi-automatic operation of nails and ventilation duct plates. The operation process is completed by the cooperation of various functional mechanisms, with a high degree of standardization. There is no need to make operation judgments based on human experience. Once the process is verified, it can realize assembly line operation, and the product quality is guaranteed. At the same time, with the help of the material storage and supply system, multiple nails can be continuously welded, which improves work efficiency. Attached Figure Description

Detailed Implementation
[0032] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.
[0033] according to Figures 1 to 12As shown: This embodiment provides a semi-automated high-efficiency welding device for sound-absorbing cotton panels, including a device support, a material storage and feeding system, a base platform 100 with an electrode working section, and a moving platform 300 installed on the device support;
[0034] The material storage and supply system includes a feeder 400, a conveying mechanism, and a feeding mechanism. The system transports nails 800 one by one to the moving platform 300. The moving platform 300 is mounted and fixed to the upper part of the equipment support via a slide rail mechanism 200 and slides along the welding direction. The second electrode working part 700 on the moving platform 300 welds and fixes the nails 800 to the ventilation duct plate 900 of the base platform 100. The second electrode working part 700 performs point-like operations, completing the welding of one nail 800 with each action. The base platform 100 is mounted and fixed to the lower part of the equipment support, directly below the sliding stroke of the moving platform 300. The upper plane of the base platform 100 forms the first electrode working part 101, which has a larger area and length to facilitate welding operations with the second electrode working part 700 during movement. All the above actions are actively controlled mechanically, with manual assistance for positioning, switching signals, etc. The specific implementation structure of each component is described below.
[0035] The equipment support frame is constructed by welding profiles. In addition to the necessary support components, it mainly includes two sets of parallel crossbeams. The two sets of crossbeams are arranged vertically. The moving platform 300 is installed on the upper crossbeam, and the base platform 100 is installed on the lower crossbeam. During the sliding process of the moving platform 300 through the slide rail mechanism 200, it is always located directly above the base platform 100. The two can work together to complete the welding operation.
[0036] A power distribution box 102 is also installed on the outside of the left side of the equipment bracket. The power distribution box 102 is connected to the first electrode working part 101 and the second electrode working part 700 to provide electrical energy to meet the welding operation.
[0037] The feeder 400 of the material storage and feeding system is also installed on the upper crossbeam and located at the outer end. The feeder 400 uses a vibratory plate, and its bottom is assembled through a shock-absorbing support to prevent the vibration of the feeder 400 from affecting other components installed on the equipment support.
[0038] The conveying mechanism of the material storage and feeding system includes a first conveying plate 501 and a second conveying plate 502 with a split structure. The first conveying plate 501 is installed on the upper crossbeam, and the second conveying plate 502 is installed on the moving platform 300. At the same time, the feeding mechanism of the material storage and feeding system is installed at the bottom of the moving platform 300 and cooperates with the second electrode working part 700 to complete the feeding action of the nail 800.
[0039] The mobile platform 300 is a box structure, which mainly houses a pressurized gas supply system. The pressurized gas supply system is a conventional technology and will not be described in detail here. The pressurized gas supply system is connected to an external pressurized gas pump system to meet the power needs of the first linear drive mechanism 602 and the second linear drive mechanism 701. The first linear drive mechanism 602 and the second linear drive mechanism 701 are cylinders, and their extension and retraction actions are met by supplying pressurized gas.
[0040] A second linear drive mechanism 701 is installed on the right side of the mobile platform 300. The second linear drive mechanism 701 is vertically distributed. The second electrode working part 700 is installed at the end of the drive rod at the lower part of the second linear drive mechanism 701. The second electrode working part 700 is a cylindrical block electrode plate structure. Its side is connected to the power distribution box 102 through a cable. A magnet 702 is installed inside the second electrode working part 700. The magnet 702 is set close to the bottom surface of the electrode working part. Under the premise that the second electrode working part 700 is capable of welding, it can attract the circular piece 801 of the nail 800 through its magnet 702. Then, the second linear drive mechanism 701 will drive the nail 800 into the sound-absorbing cotton layer 901 and into contact with the ventilation duct plate 900, thus meeting the welding conditions.
[0041] At the bottom of the mobile platform 300, i.e., on the left side of the second electrode working section 700, the feeding mechanism of the material storage and feeding system is installed. The feeding mechanism includes a slider 600, a track 601, and a first linear drive mechanism 602. The first linear drive mechanism 602 and the track 601 are respectively fixed on the bottom surface of the mobile platform 300. The slider 600 is slidably disposed within the track 601, wherein:
[0042] The working end of the slider 600 is connected to the drive rod of the first linear drive mechanism 602, which is used to drive the slider 600 to slide within the track 601. The right end of the slider 600 is provided with a feeding port 604, which is an L-shaped opening structure. The side of the feeding port 604 is sealed by the track 601. A limiting piece 605 is provided at the right opening of the feeding port 604 and is rotatably connected to it. The limiting piece 605 is rotatably connected to the slider 600 and is in contact with the inner wall of the track 601 and cannot rotate. When the slider 600 slides away from the inner wall of the track 601, the limiting piece 605 can open outward to allow the nail 800 to be sent out.
[0043] To ensure that the nail 800 can be normally transported between the track 601, the slider 600, and the conveying mechanism, the track 601 is also provided with a feeding port 603 that communicates with the discharge port 604. The feeding port 603 includes two sections: one section is set for the nail 800 in the conveying mechanism to enter the discharge port 604, and the other section is used to facilitate the sliding of the nail 800 in the discharge port 604, so that the two sections together form a right-angled L-shaped structure.
[0044] In the overall structure formed by the second electrode working unit 700 and the feeding mechanism, in order to better understand the cooperation effect between the components, the specific working process includes:
[0045] The nail 800 enters the feed inlet 604 behind the track 601 and eventually reaches the initial position of the feed inlet 603. At this time, the main body of the nail 800 is located in both the feed inlet 604 and the feed inlet 603, while the disc 801 of the nail 800 is located on the upper part of the track 601. When the slider 600 slides, the nail 800 slides from left to right simultaneously in both the feed inlet 604 and the feed inlet 603. Since the position of the feed inlet 603 is fixed, the nail 800 disengages from the feed inlet 603 during this process but remains within the feed inlet 604. The disc 801 of the nail 800 is also located on the upper part of the slider 600. After the sliding action is completed, the nail 800 is located directly below the second electrode working part 700. At this time, because the disc 801 of the nail 800 is close to the second electrode working part 700, the nail 800... The circular piece 801 can be adsorbed onto the bottom of the second electrode working part 700, the position of the nail 800 is fixed, and then the slider 600 slides into the track 601 to the initial position. At this time, the limiting piece 605 contacts the nail 800, and the limiting piece 605 will automatically open outward. Then the back side of the limiting piece 605 will contact the inner wall of the track 601, so that the limiting piece 605 rotates and resets to the initial position inside the feed port 604, sealing the right opening of the feed port 604, which can prevent other nails 800 from sliding out and falling at this position. At this time, a feeding action is completed. The second electrode part can slide downward under the drive of the second linear drive mechanism 701 and insert the nail 800 into the sound-absorbing cotton layer 901. The end of the nail 800 contacts the ventilation duct plate 900 to complete the welding action.
[0046] Furthermore, to better facilitate operator operation, a switch handle 301 is provided on the upper part of the mobile platform 300 and rotated therewith. The switch handle 301 is used to control the execution of welding actions. The switch handle 301 is mounted via a long support rod, allowing it to be positioned away from the mobile platform 300. This allows the operator to use the handle from any location around the equipment and provide an actionable switch signal to initiate welding operations. This ensures a good field of vision during the operation, guaranteeing the accuracy and safety of the welding work. Additionally, the switch handle 301 can be used to slide the mobile platform 300 along the slide rail mechanism 200, thereby changing the position of the welding operation.
[0047] The base platform 100 has a slender structure. The surface of the first electrode working part 101 is the top surface of the entire base platform 100. An electrode plate connected to the distribution box 102 is laid flat on the surface of the first electrode working part 101. The first electrode working part 101 can meet the welding operations of multiple welding potentials in a straight line. In cooperation with the sliding second electrode working part 700, the operator controls the sliding platform 300 to slide through the switch handle 301. During this sliding process, welding operations are performed on multiple nails 800 in a straight line. Then, the ventilation duct plate 900 is moved to perform welding operations on the next position.
[0048] The specific structure of the nail 800 material storage and feeding system, as well as the nail 800 conveying process within the system, are described below, including:
[0049] The feeder 400 uses a vibratory feeder, which continuously conveys the nails 800 from inside to outside through a conveying process. During the conveying process, the disc 801 of the nails 800 faces downwards, and the ends of the nails 800 are located at the top.
[0050] The conveying mechanism includes a split-structure first conveying plate 501 and a second conveying plate 502. The first conveying plate 501 and the second conveying plate 502 are respectively composed of a base plate 503 and a front plate 504 bolted together. A gap is maintained between the base plate 503 and the front plate 504, forming a channel 505 for the movement of the circular piece 801 of the nail 800. The front plate 504 has two sets distributed left and right, with a gap also maintained between the two sets of front plates 504, forming a clearance channel for the movement of the nail 800. When the nail 800 is conveyed inside the first conveying plate 501 and the second conveying plate 502, the circular piece 801... 01 is located in the channel 505 between the base plate 503 and the front plate 504, and the nail 800 is exposed on the outside of the front plate 504 at the clearance channel position; the specific implementation shape of the first conveyor plate 501 and the second conveyor plate 502 are vertically distributed as a whole, but the end of the first conveyor plate 501 near the feeder 400 and the end of the second conveyor plate 502 near the feeding mechanism are both arc-shaped, and are bent to the feeder 400 and the feeding mechanism respectively, so as to ensure that the positions of the nails 800 entering and exiting are correspondingly distributed and interconnected, and the nails 800 can be conveyed between different components;
[0051] The first conveyor plate 501 is located at the top and is fixed on the equipment bracket. The top of the first conveyor plate 501 is connected to the discharge port of the feeder 400. The bottom of the channel 505 of the first conveyor plate 501 is sealed by an openable baffle 507.
[0052] Furthermore, the baffle 507 is rotatably connected to the front plate 504 of the first conveyor plate 501, and is also pulled upward by a tension spring 508 to maintain the sealing effect on the opening of the channel 505 of the first conveyor plate 501. The outer side of the baffle 507 is provided with a first working part 509 and a second working part 510 protruding outward. The first working part 509 is located at the bottom end of the channel 505 and plays a sealing role. The second working part 510 is located at the lower part of the baffle 507 and is used to contact the second conveyor plate 502. In this way, the baffle 507 can be rotated so that the first working part 509 leaves the position of the channel 505, thus opening the channel 505 of the first conveyor plate 501 and allowing the nail 800 to be conveyed downward into the channel 505 of the second conveyor plate 502.
[0053] The second conveyor plate 502 is located at the bottom and is fixed on the mobile platform 300. The bottom end of the second conveyor plate 502 is connected to the feed inlet of the feeding mechanism. The top end of the second conveyor plate 502 is correspondingly set to the bottom end of the first conveyor plate 501. The side of the second conveyor plate 502 is provided with a lever 506 for opening the baffle 507. The lever 506 is located at the front left side of the second conveyor plate 502. Considering the operating accuracy of the equipment, there is a small gap in height between the first conveyor plate 501 and the second conveyor plate 502. However, this gap can meet the smooth conveying effect of the nail 800 between the first conveyor plate 501 and the second conveyor plate 502.
[0054] During use, after the nail 800 enters the channel 505 of the first conveyor plate 501 and the second conveyor plate 502, it is conveyed downwards by gravity. It achieves autonomous feeding by utilizing the gap between the working points, thus meeting the usage requirements. However, the conveying effect between the first conveyor plate 501 and the second conveyor plate 502 is described in detail below, based on the above structure:
[0055] After the nail 800 enters the first conveyor plate 501, the number of nails 800 will remain saturated because the bottom end of the channel 505 of the first conveyor plate 501 is sealed by the baffle 507. The number of nails 800 inside the channel 505 of the second conveyor plate 502 is limited and will gradually decrease during use. It is necessary to periodically obtain nails 800 from the position of the first conveyor plate 501. When needed, the operator slides the moving platform 300, at which time the second conveyor plate 502 slides towards the position of the first conveyor plate 501 until it is directly below the first conveyor plate 501. At the same time, the lever 506 and... When the baffle 507 contacts, the baffle 507 rotates 90 degrees. At this time, the channel 505 of the first conveyor plate 501 opens, and the nail 800 enters the channel 505 of the second conveyor plate 502 from the bottom of the channel 505. When the number of nails 800 inside the channel 505 of the second conveyor plate 502 is saturated, the second conveyor plate 502 can slide in the opposite direction. At this time, the paddle 506 disengages from the baffle 507, and the baffle 507 resets under the action of the tension spring 508. The channel 505 of the first conveyor plate 501 is sealed, and the nail 800 will not continue to fall. The second conveyor plate 502 will also leave and continue the welding operation.
[0056] In the above description of the semi-automatic high-efficiency welding equipment for sound-absorbing cotton panels, during the welding operation, the operator only needs to slide the moving platform 300 and give a switch signal to the control system of the control box 103 to carry out the welding operation. The control of key factors such as the welding position of the nail 800 and the welding current are all executed by the pre-programmed system of the equipment. This technical solution has been verified in conjunction with the specific precision of the equipment. By using appropriate technical parameters to operate the equipment, the welding quality can be guaranteed to meet the relevant requirements. Its overall use saves manpower to a certain extent, improves work efficiency, enhances the level of standardized management, and avoids the impact of human factors on the process flow.
[0057] The above description is only a preferred embodiment of the present invention. Any technical solution that achieves the purpose of the present invention by essentially the same means shall fall within the protection scope of the present invention.
