AI Technical Summary
Existing anti-spatter robotic welding platforms cannot adjust their protection range when the robot's welding position changes, resulting in blind spots or obstruction of the welding path. Furthermore, traditional protective devices are prone to instability due to uneven force distribution.
The protective components, including connecting arms, connecting rods, and limiting grooves, are used to adjust the angle of the protective cover. The screw drive driven by pulleys and synchronous belts ensures that the protective components move smoothly along the welding table. Combined with the limiting block and sliding groove guide, precise control is achieved.
It enables real-time adjustment of the angle and position of the protective cover, which can effectively block spatter without obstructing the welding path, ensuring the stability and accuracy of the welding operation.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of welding protection, and in particular to an anti-spatter robotic welding platform. Background Technology
[0002] With the development of industrial automation, robotic welding has been widely used in automobile manufacturing, machining and other fields due to its high efficiency and stable precision. However, the welding process generates a large amount of high-temperature spatter, which can damage the surface of the robot. Therefore, there is a special need for an anti-spatter robotic welding platform.
[0003] Existing welding protection measures, such as fixed baffles or protective covers, can only cover specific areas. When the robot's welding position changes, the protection range cannot be adjusted accordingly, which can easily lead to blind spots. Traditional protective covers have fixed angles. If the angle is too large, it can easily block the welding path. If the angle is too small, it cannot effectively block spatter. It is difficult to balance the protection effect and the welding operation space. Some movable protective devices use single rails or single screw drives, which can easily cause the protective components to shift or jam due to uneven force, affecting the stability of movement and thus reducing the protection accuracy.
[0004] To address the aforementioned issues, an anti-spatter robotic welding platform is proposed. Utility Model Content
[0005] The purpose of this invention is to provide an anti-spatter robotic welding platform to address the problems of existing anti-spatter robotic welding platforms mentioned in the background section.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an anti-spatter robotic welding platform, comprising a welding table, a protective component being provided above the welding table, and movable components being provided on both sides of the welding table; The protective assembly includes side plates arranged on both sides of the welding table, a protective cover rotatably connected between the side plates, a connecting arm between the side plates and the protective cover, and the top end of the connecting arm rotatably connected to the protective cover. A first limiting groove is opened on the surface of the side plate, and a connecting rod is passed through the end of the connecting arm, and the connecting rod passes through the first limiting groove and is slidably connected to the first limiting groove.
[0007] Preferably, the protective component further includes a groove formed on one side of the side plate, and a limiting block is integrally formed on one side of the side plate.
[0008] Preferably, the moving component includes lead screws installed on both sides of the welding table, a second limiting groove is provided on both sides of the welding table, a baffle is integrally formed on both sides of the welding table, a pulley is installed on the connecting end of the lead screw, and a synchronous belt is provided on the outer side of the pulley.
[0009] Preferably, there are two sets of baffles, each located above the lead screw, and the width of the baffle is greater than the diameter of the lead screw.
[0010] Preferably, the baffle is disposed in the slide groove, and the baffle is slidably connected to the slide groove.
[0011] Preferably, the limiting block is disposed in the second limiting groove, and the limiting block is slidably connected to the second limiting groove.
[0012] Preferably, the side plate and the lead screw are connected by a helical drive.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The protective cover achieves angle adjustment through the cooperation of the connecting arm, connecting rod and the first limiting groove. The angle of the protective cover can be adjusted according to the posture of the welding arm. It can increase the protection range and block low-altitude splashes when the welding arm is close to the workpiece, and reduce the angle to avoid blocking the welding path when the welding arm is raised. 2. The two sets of lead screws are driven to rotate by pulleys and synchronous belts. With the double guidance and constraint of limit blocks and second limit grooves, baffles and slides, the protective components can be smoothly translated along the welding table axis.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0017] Example like Figure 1-3As shown, the assembly includes a welding table 1, a protective component 2 above the welding table 1, and movable components 3 on both sides of the welding table 1. The protective component 2 includes side plates 201 on both sides of the welding table 1, a protective cover 202 rotatably connected between the side plates 201, a connecting arm 203 between the side plates 201 and the protective cover 202, and the top end of the connecting arm 203 rotatably connected to the protective cover 202. A first limiting groove 204 is opened on the surface of the side plate 201, and a connecting rod 205 is passed through the end of the connecting arm 203. The connecting rod 205 passes through the first limiting groove 204 and is slidably connected to the first limiting groove 204. The protective component 2 also includes a sliding groove 206 opened on one side of the side plate 201, and a limiting block 207 integrally formed on one side of the side plate 201.
[0018] It should be noted that in this embodiment, the welding table 1 is used as the basic supporting structure, and a protective component 2 is arranged on top to block the spatter generated during welding. The protective cover 202 is an arc-shaped transparent high-temperature resistant plate, and its two ends are rotatably connected to two sets of side plates 201 through pivots, covering the area above the welding table 1 to directly block the spatter. The top of the connecting arm 203 is rotatably connected to the middle of the protective cover 202 through a hinge, and the end has a through hole. The first limiting groove 204 is opened on the surface of the side plate 201 to limit the sliding trajectory of the connecting rod 205. The connecting rod 205 passes through the through hole at the end of the connecting arm 203 and the first limiting groove 204, and its two ends protrude outward from the side plate 201 and are connected to the driving component at the bottom of the side plate 201, which can drive the connecting arm 203 to slide along the first limiting groove 204. The slide groove 206 is a rectangular groove opened on the inner side of the side plate 201 to accommodate the baffle 303 of the moving component 3. The limiting block 207 is a rectangular block integrally formed on one side of the side plate 201. The protective cover 202 is shaped and matches the second limiting groove 302. It is slidably connected to the second limiting groove 302 of the welding table 1. During the welding process, the robot welding arm will swing up and down. The protective component 2 needs to adjust the angle of the protective cover 202 in real time so that it does not block the welding arm and can block the spatter. A distance sensor can be installed inside the protective cover 202 to monitor the position of the welding arm and transmit the data to the main controller. The controller calculates the required angle of the protective cover 202 according to the position of the welding arm and controls the driving component at the bottom of the side plate 201 to drive the connecting rod 205 to slide along the first limiting groove 204. The connecting rod 205 drives the end of the connecting arm 203 to move. The top of the connecting arm 203 pulls or pushes the protective cover 202, so that the protective cover 202 rotates around the axis of the side plate 201 until the target angle is reached. During the welding process, the above adjustment is continuously performed to ensure that the protective cover 202 is always in the optimal protective position. After the welding is completed, the protective cover 202 is reset for easy loading and unloading of workpieces. In this anti-splash robotic welding platform, the control of sensors and drive components by the main controller is within the scope of existing technology. Its core function is to receive signals, process information and issue instructions, which will not be elaborated on here. This section will only describe the mechanical structure linkage and working process of the device.
[0019] like Figure 4 , 5 As shown, the moving component 3 includes a lead screw 301 installed on one side of the welding table 1. The welding table 1 has second limiting grooves 302 on both sides. The welding table 1 has baffles 303 integrally formed on both sides. The connecting end of the lead screw 301 is equipped with pulleys 304. The outer side of the pulleys 304 is provided with a synchronous belt 305.
[0020] It should be noted that in this embodiment, the moving component 3 is used to drive the protective component 2 to move along the length of the welding table 1 to adapt to different welding positions. The lead screw 301 is installed on both sides of the welding table 1, and the two sets of lead screws 301 are arranged in parallel. The second limiting groove 302 is a rectangular groove opened on both sides of the welding table 1 to accommodate the limiting block 207 on one side of the side plate 201 and limit the movement direction of the side plate 201. The width of the baffle 303 integrally formed on both sides of the welding table 1 is greater than the diameter of the lead screw 301 to prevent welding spatter from entering the lead screw 301. A pulley 304 with the same number of teeth is installed on the same end of each lead screw 301. A synchronous belt 305 is sleeved on the outside of the pulley 304 to ensure that the two sets of lead screws 301 rotate synchronously. When the robot's welding position changes, the moving component 3 drives the protective component 2 to move synchronously. First, the drive motor at the end of one set of lead screws 301 is started. The drive motor drives one set of lead screws 301 to rotate, and the pulley 305 rotates through the belt. The meshing transmission of wheel 304 and synchronous belt 305 causes another set of lead screws 301 to rotate synchronously. When the two sets of lead screws 301 rotate, the two side plates 201 connected to them move linearly along the axis of the lead screws 301 under the action of thread friction. Since the two sets of lead screws 301 rotate synchronously and have the same thread parameters, the moving speed and direction of the two side plates 201 are consistent, and the error can be ignored, ensuring that the protective component 2 moves smoothly as a whole. The limiting block 207 at the bottom of the side plate 201 slides along the second limiting groove 302, restricting the side plate 201 to move only axially. At the same time, the baffles 303 on both sides of the welding table 1 are still set in the sliding groove 206 of the side plate 201, further enhancing the stability of the movement process and preventing the protective component 2 from deviating during translation. By controlling the number of rotations of the drive motor, the rotation angle of the lead screw 301 can be precisely controlled, thereby achieving precise control of the moving distance of the protective component 2 and ensuring that it can accurately reach the preset welding position. Optionally, a servo motor can be used as the drive motor, and a braking component, such as an electromagnetic brake, can be installed at the connection between the drive motor and the lead screw 301 to further improve the control accuracy and operational safety of the moving component 3.
[0021] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-5When the robot's welding position changes, the moving component 3 drives the protective component 2 to move synchronously. First, the drive motor at the end of a set of lead screws 301 is started. The drive motor drives one set of lead screws 301 to rotate. Through the meshing transmission of pulley 304 and synchronous belt 305, the other set of lead screws 301 rotates synchronously. When the two sets of lead screws 301 rotate, the two side plates 201 connected to them move linearly along the axis of lead screws 301 under the action of thread friction. Since the two sets of lead screws 301 rotate synchronously and have the same thread parameters, the moving speed and direction of the two side plates 201 are consistent, and the error can be ignored, ensuring that the protective component 2 moves smoothly as a whole. The limiting block 207 at the bottom of the side plate 201 slides along the second limiting groove 302, restricting the side plate 201 to move only axially. At the same time, the baffles 303 on both sides of the welding table 1 are still located in the sliding groove 206 of the side plate 201, further enhancing the stability of the movement process and preventing the protective component 2 from shifting during translation. By controlling the number of rotations of the drive motor, the rotation angle of the lead screw 301 can be precisely controlled, thereby achieving precise control of the moving distance of the protective component 2 and ensuring that it can accurately reach the welding position. During the welding process, the robot welding arm swings up and down. The protective component 2 needs to adjust the angle of the protective cover 202 in real time so that it neither obstructs the welding arm nor blocks spatter. A distance sensor is installed inside the protective cover 202 to monitor the position of the welding arm and transmit the data to the main controller. The controller calculates the required angle of the protective cover 202 based on the position of the welding arm and controls the driving component at the bottom of the side plate 201 to drive the connecting rod 205 to slide along the first limiting groove 204. The connecting rod 205 drives the end of the connecting arm 203 to move. The top of the connecting arm 203 pulls or pushes the protective cover 202, causing the protective cover 202 to rotate around the axis of the side plate 201 until the target angle is reached. During the welding process, the aforementioned connecting arm is continuously adjusted to ensure that the protective cover 202 is always in the optimal protective position. After welding is completed, the protective cover 202 is reset to facilitate the handling of workpieces.
