Description

Technical Field

[0001] This utility model relates to the field of welding robot technology, and in particular to a ceiling-rail inverted intelligent welding device. Background Technology

[0002] With the continuous adjustment and transformation and upgrading of industrial structure, the intelligent equipment industry represented by robots has developed rapidly and has become an important benchmark for technological innovation in the new era. Welding robots, as a new type of equipment in the welding industry, replace manual welding work. Visual positioning, as a relatively important technology in industrial robots, enables welding robots to autonomously find workpieces and perform welding work.

[0003] CN117047247B discloses an automated welding robot for automotive sheet metal, including a base, a robotic arm mounted on the base, and a resistance welding device mounted on the output end of the robotic arm. The resistance welding device includes a frame, a large arm mounted on the frame, a first electrode mounted on the end of the large arm away from the frame, and a second electrode mounted on the frame. The first electrode and the second electrode are coaxially arranged, and the second electrode can reciprocate up and down along the central axis of the first electrode. The robot also includes a cleaning unit for cleaning the ends of the first electrode and the second electrode that are in contact with the surface of the weldment. The cleaning unit includes a moving component, the output end of which is connected to the cleaning component. The moving component drives the cleaning component to move in three-dimensional space, so that the cleaning component slides into contact with the ends of the first electrode and the second electrode that are in contact with the surface of the weldment.

[0004] CN106041260B discloses a lightweight track-type five-axis welding robot, which includes X-axis, Y-axis and Z-axis movement modules. The motion output end of the Y-axis movement module is perpendicularly and fixedly connected to the X-axis movement module. It also includes first and second rotation modules. A height adjustment seat is fixed on the X-axis direction motion output end of the X-axis movement module. The Z-axis movement module includes a track, and a transmission rack is fixed on the track along the Z-axis direction. The track can be magnetically attached to the surface of the workpiece to be welded. A Z-axis base is set above the track, and a Z-axis rotation output device is fixed on the Z-axis base. A transmission gear is fixed on the rotation output end of the Z-axis rotation output device, and the transmission gear meshes with the transmission rack. The first rotation module includes a first rotation shaft base fixed on the height adjustment seat, and a second rotation shaft base is rotatably connected to the first rotation shaft base.

[0005] In existing technologies, general building steel structures, bridge steel structures, and other workpieces can be welded using integrated welding workstations. However, when processing long workpieces such as engineering machinery and rail transit lights, a ceiling-mounted welding workstation is required. Currently, welding robots are mounted on sliding tracks for mobile welding. However, during welding, metal shavings may fly onto the sliding tracks, and dust and impurities in the work environment can easily adhere to the sliding tracks, affecting the movement of the welding robot. Therefore, the sliding tracks need to be cleaned. Currently, there are some specialized track cleaning devices, but they cannot provide a direct view of the contamination and cleaning status of the sliding tracks, nor can they control the cleaning time. In addition, setting up a separate cleaning device is costly. Utility Model Content

Detailed Implementation

[0032] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0034] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices. "Fixed" or "fixed connection" generally refers to common mechanical connection methods, such as threaded connections, welding, or bonding.

[0035] In existing technologies, general building steel structures, bridge steel structures, and other workpieces can be welded using integrated welding workstations. However, when processing long workpieces such as engineering machinery and rail transit lights, a ceiling-mounted welding workstation is required. Currently, a welding robot 3 is mounted on a sliding track 2 for mobile welding. However, during welding, iron filings may splatter onto the sliding track 2, and dust and impurities in the work environment can easily adhere to the sliding track 2, affecting the movement of the welding robot 3 on the sliding track 2. Therefore, the sliding track 2 needs to be cleaned. Currently, there are some specialized equipment for cleaning tracks, but it is not possible to intuitively understand the contamination and cleaning status of the sliding track 2, nor can the cleaning time be controlled. In addition, setting up a separate cleaning device is costly.

[0036] This utility model provides a top rail inverted intelligent welding device, such as... Figure 1As shown, in this embodiment, the welding device includes a frame 1, a sliding rail 2 disposed on the frame 1, and a welding robot 3 and a cleaning mechanism 4 slidably disposed on the sliding rail 2; a slider 5 is disposed on the sliding rail 2 and is connected to the welding robot 3; and a driving mechanism is provided to drive the slider 5 to move on the sliding rail 2 to drive the horizontal movement of the welding robot 3; in this embodiment, the welding robot 3 includes at least a robotic arm and a welding torch disposed on the robotic arm.

[0037] In this embodiment, a camera assembly 7 is installed on the side of the slider 5. This camera assembly 7 includes at least a camera and a signal transmission unit, used to remotely transmit the captured image to the controller for monitoring. The camera faces the sliding track 2 to capture real-time images of the sliding track 2. A connecting block 6 is connected to the top of the slider 5 by screws. Horizontally opened slots 61 are provided on both sides of the connecting block 6, and an electromagnetic component 62 capable of controlling the magnetic on / off state is installed inside the slots 61. That is, when the electromagnetic component 62 is energized, it generates a magnetic attraction force; when the electromagnetic component 62 is de-energized, it loses its magnetic attraction force. Two cleaning mechanisms 4 are provided, respectively located at both ends of the sliding track 2. The cleaning mechanisms 4 are slidably mounted on the sliding track 2. Figure 5 and Figure 6 As shown, the cleaning mechanism 4 includes a sliding seat 41, a cleaning component, a plug-in block 42, and an adsorption iron sheet 43. The sliding seat 41 is slidably mounted on the sliding track 2. The cleaning component and the plug-in block 42 are both mounted on the sliding seat 41. The cleaning component starts working to clean the sliding track 2 when the sliding seat 41 moves. The plug-in block 42 is fixed on the side of the sliding seat 41 near the connecting block 6. The end of the plug-in block 42 near the slot 61 is connected to the adsorption iron sheet 43. When the slider 5 moves close to the sliding seat 41, the plug-in block 42 can be at least partially inserted into the slot 61.

[0038] In the image captured by the camera component 7, when a stain is observed on a section of the track that needs cleaning, the slider 5 is moved towards the cleaning mechanism 4 in that track direction until the plug block 42 is inserted into the slot 61. At this time, the electromagnetic component 62 is energized (a position sensor can be set to automatically turn on and off the power, automatically turning on the power when the plug block 42 is detected to be inserted). The electromagnetic component 62 then attracts the adsorption iron sheet 43 on the plug block 42, and then controls the slider 5 to move in the direction to be cleaned. Due to the adsorption force of the electromagnetic component 62, the cleaning component moves together with the slider 5, and then the cleaning component is activated to clean the track. The sliding track 2 that the slider 5 moves through is cleaned. When the slider 5 moves repeatedly on the sliding track 2 once, the sliding track 2 is cleaned twice. After the cleaning is completed, the cleaning mechanism 4 is moved back to its original position, and then the power is turned off to separate the cleaning component from the slider 5.

[0039] It should be noted that, in order to avoid frequent contact between the slider 5 and the cleaning mechanism 4 when the welding robot 3 is working, the movement path of the slider 5 on the sliding track 2 is set to be less than the total length of the sliding track 2 when the welding robot 3 is working. A sliding section is reserved on the side of the cleaning mechanism 4 on the sliding track 2 so that the slider 5 can only enter when cleaning is required. When cleaning is required, the slider 5 enters the sliding block and contacts the cleaning mechanism 4.

[0040] This invention, by setting camera components 7 on both sides of the slider 5, can clearly obtain the real-time status of the track and determine whether cleaning is required; at the same time, a cleaning mechanism 4 is set on the sliding track 2, which is driven by the slider 5 to clean the sliding track 2, eliminating the need for a separate drive mechanism to drive the cleaning components, saving costs, and the cleaning operation of this invention is convenient to control, requiring no manual control of the cleaning.

[0041] To facilitate easy installation and removal of the camera assembly 7, and especially to avoid wiring issues, a battery module is installed within the camera assembly 7 for convenient charging and maintenance; such as Figure 4 As shown, the camera component 7 is detachably mounted on the slider 5. The slider 5 has a mounting groove 51. The end of the camera component 7 near the slider 5 is provided with a sliding mounting block that cooperates with the mounting groove 51. During installation and removal, the camera component 7 can be installed or removed by simply aligning the sliding mounting block with the mounting groove 51 and inserting or pulling it out.

[0042] In order to effectively and thoroughly clean sliding track 2; such as Figure 5 and Figure 6 As shown, the cleaning components are configured as a drive motor 44, a cleaning disc 45, and a dust collection cylinder 46. The drive motor 44 is installed at the upper end of the sliding seat 41, and the cleaning disc 45 is installed at the lower end of the sliding seat 41, with the bottom of the cleaning disc 45 in contact with the surface of the sliding track 2. The motor shaft of the drive motor 44 extends downward and is connected to the center of the cleaning disc 45, driving the cleaning disc 45 to rotate. The dust collection cylinder 46 is located on the side of the cleaning disc 45 and has an opening for the side of the cleaning disc 45 to be inserted. Inside the dust collection cylinder 46, a scraper is provided, which contacts the edge of the cleaning disc 45. When the cleaning disc 45 rotates to clean, the dust and impurities adsorbed on the cleaning disc 45 enter the dust collection cylinder 46 under the action of centrifugal force, and the impurities on the cleaning disc 45 are scraped off into the dust collection cylinder 46 by the scraper, preventing the impurities from returning to the sliding track 2 after cleaning, and scraping and cleaning the edge of the cleaning disc 45 to ensure the cleaning effect of the sliding track 2.

[0043] To prevent dust from adhering to the camera component 7 and ensure the clarity of the captured image, a cleaning groove 47 is provided at the end of the sliding base 41 facing the slider 5. A cleaning cotton is placed in the cleaning groove 47. When the slider 5 is connected to the cleaning mechanism 4 for cleaning, the camera component 7 is inserted into the cleaning groove 47 and comes into contact with the cleaning cotton to clean the camera component 7.

[0044] To improve the stability of the welding robot 3 moving on the sliding track 2, slide rails are provided at both the upper and lower ends of the sliding track 2, and a sliding groove is provided in the middle of the sliding track 2. A limiting protrusion is provided on the mounting plate 8 near the sliding track 2. The limiting protrusion is inserted into the sliding groove and abuts against the sliding track 2. Through the limiting at the upper and lower ends and the middle limiting protrusion, the tilting of the welding robot 3 is prevented when it moves. The multiple limiting measures ensure the stability of the movement.

[0045] To enable the welding robot 3 to be easily installed on various types of sliding surfaces; such as Figure 2 and Figure 3 As shown, the welding robot 3 is fixed on the mounting plate 8. Two sliders 5 are set, located at the upper and lower ends of the sliding track 2 respectively and cooperating with the slide. The sliders 5 are detachably mounted on the mounting plate 8 by bolts. Multiple mounting holes 81 are evenly opened on the mounting plate 8 along its height direction, so that the two sliders 5 can be installed at different heights on the mounting plate 8, so that they can be adapted to the sliding track 2 at different heights.

[0046] In order to improve the service life of the sliding rail 2 and the slider 5, reduce the wear of both, and improve the stability of movement on the sliding rail 2, a wear-resistant layer is provided on the contact surface between the slider 5 and the slide rail. This wear-resistant layer can be made of steel and a wear-resistant coating.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
