Description

Technical Field

[0001] This application belongs to the field of welding technology, and in particular relates to a welding device. Background Technology

[0002] Thin-walled cylindrical workpieces have been applied in high-tech fields such as aerospace, automotive industry and medical devices due to their excellent mechanical properties and lightweight characteristics.

[0003] Due to the thin and light nature of thin-walled cylindrical workpieces, it is difficult to align the weld joints of two thin-walled cylindrical workpieces during the welding process, resulting in unstable welds or excessively large weld points. In the existing technology, the thin-walled cylindrical workpieces are usually manually clamped to perform the welding joint docking work, thereby ensuring that the weld joints are completely aligned for welding.

[0004] However, manual docking is inefficient, the welding process can irritate the eyes, and the welding accuracy cannot be guaranteed. Utility Model Content

[0055] Reference Appendix Figures 1 to 4 This application provides a welding device, including a base assembly 100, a dual clamping assembly 200, a carriage assembly 300, a welding torch assembly 400, an image acquisition assembly 500, and a control module.

[0056] Two clamping assemblies 200 are slidably mounted on the base assembly 100 along the first direction, either forward or backward. The two clamping assemblies 200 are used to rotatably clamp two parts to be welded and move closer or further apart from each other via the base assembly 100. The slide assembly 300 is located between the two clamping assemblies 200. The welding torch assembly 400 is rotatably mounted on the slide assembly 300 and moves through the slide assembly 300 in the second and third directions, which are perpendicular to each other. An image acquisition assembly 500 is located between the two clamping assemblies 200 and is used to acquire the docking status of the two parts to be welded. The control module is electrically connected to the base assembly 100, the two clamping assemblies 200, the slide assembly 300, the welding torch assembly 400, and the image acquisition assembly 500.

[0057] The control module aligns the welding joints of the two parts to be welded by the base assembly 100 and the two clamping assemblies 200, improving the docking efficiency. Furthermore, the image acquisition assembly 500, welding torch assembly 400, and slide assembly 300 control the welding torch 401 to move to one side of the welding joint for precise automatic welding without the need for manual monitoring, thus improving the safety factor of the welding operation and ensuring welding accuracy.

[0058] Reference Appendix Figures 1 to 5 In some embodiments, the base assembly 100 includes a guide rail 101, a first motor 103, a transmission component 102, and a limiting component 600. The guide rail 101 extends along a first direction, and two clamping assemblies 200 are slidably disposed on the guide rail 101. At least one first motor 103 is disposed on one side of the guide rail 101 and is electrically connected to a control module. At least one transmission component 102 is connected to the actuating end of the first motor 103, and the transmission component 102 is threadedly connected to the two clamping assemblies 200 respectively. The first motor 103 drives the two clamping assemblies 200 to move closer to or further away from each other through the transmission component 102. At least two limiting components 600 are disposed at both ends of the guide rail 101, and the limiting components 600 are used to limit the sliding stroke of the two clamping assemblies 200 along the first direction.

[0059] Specifically, the guide rail 101 includes two slide rails, the extension direction of the guide rail 101 is the first direction, the two slide rails are fixedly connected by a short beam, and the two ends of the guide rail 101 are provided with a first motor 103 mounting plate, and the first motor 103 is located between the two slide rails through the first motor 103 mounting plate.

[0060] The first motor 103 includes an actuating end and an input end. The input end of the first motor 103 is electrically connected to the power supply and the control module. The actuating end of the first motor 103 is connected to the transmission component 102. The actuating end of the first motor 103 is used to drive the transmission component 102 to rotate relative to the guide rail 101.

[0061] The guide rail 101 is also slidably provided with two clamping component 200 mounting seats. The clamping component 200 mounting seats are threadedly connected to the transmission component 102. The clamping component 200 mounting seats are used to install the clamping components 200.

[0062] The limiting member 600 is fixed at both ends of the guide rail 101. The limiting member 600 is used to limit the sliding stroke of the clamping assembly 200 mounting base relative to the guide rail 101, thereby limiting the sliding stroke of the two clamping assemblies 200 in the forward or reverse direction of the first direction respectively. The limiting member 600 includes, but is not limited to, baffle, stop, and limiting screw.

[0063] The transmission component 102 is a lead screw. When the first motor 103 drives the transmission component 102 to rotate, the mounting base of the two clamping components 200 moves linearly relative to the transmission component 102 based on the external thread on the transmission component 102, so that the two clamping components 200 move closer or further apart on the base assembly 100.

[0064] The transmission component 102 is used to convert the rotation of the output end of the first motor 103 into linear motion of the two clamping components 200 on the base assembly 100.

[0065] In some embodiments, the base assembly 100 includes two first motors 103 and two transmission components 102. The two transmission components 102 are threadedly connected to two clamping assemblies 200 respectively. The two first motors 103 are electrically connected to a control module. The control module controls the two transmission components 102 to rotate by controlling the two first motors 103 respectively, thereby controlling the two clamping assemblies 200 to slide different or the same distance respectively.

[0066] Specifically, the two first motors 103 are respectively connected to two transmission components 102, and the threads on the two transmission components 102 are in opposite directions, so that the two first motors 103 drive the two clamping components 200 to move closer or further away from each other on the base component 100 through the two transmission components 102.

[0067] When the two first motors 103 operate simultaneously, the two clamping components 200 move on the base assembly 100 in a direction that moves closer to or further away from each other.

[0068] When the position of the workpiece to be welded on one of the clamping components 200 does not match the position of the welding gun assembly 400, the corresponding first motor 103 is operated to move the clamping component 200 to the appropriate position for welding.

[0069] The two clamping assemblies 200 are independently controlled by two first motors 103 and two transmission components 102, which improves the flexibility of any clamping assembly 200 and facilitates precise adjustment of the welding position of the workpiece to be welded.

[0070] Reference Appendix Figure 1 , 2 In some embodiments, 3, 4, and 6, two clamping components 200 are slidably disposed on the base assembly 100 along the first direction in either the forward or reverse direction. The two clamping components 200 are used to rotatably clamp two parts to be welded and move closer or further apart from each other through the base assembly 100. The clamping components 200 further include a sliding seat 201, a second motor 204, a chuck 202, a ball nut, and jaws 203. The sliding seat 201 is slidably disposed on the base assembly 100 and slides in the forward or reverse direction in the first direction. The second motor 204 is disposed on the sliding seat 201 and is electrically connected to the control module. The chuck 202 is connected to the actuating end of the second motor 204 and rotates relative to the sliding seat 201 through the second motor 204. At least two jaws 203 are slidably disposed on the chuck 202 and are used to clamp the parts to be welded so that the parts to be welded are relatively fixed or relatively released from the chuck 202.

[0071] Specifically, the two clamping assemblies 200 are used to rotate and clamp the two parts to be welded on the base assembly 100, so that the two parts to be welded are brought close to each other for docking, which facilitates subsequent welding with the welding gun assembly 400.

[0072] The ball nut is fixed on the sliding seat 201, and the sliding seat 201 is threadedly connected to the lead screw through the ball nut. When the first motor 103 drives the transmission component 102 to rotate, the transmission component 102 pushes the sliding seat 201 to slide in the forward or reverse direction along the guide rail 101.

[0073] The chuck 202 is rotatably mounted on the sliding seat 201. At least two jaws 203 are slidably mounted on the chuck 202. The two jaws 203 are used to clamp the workpiece to be welded, so that the workpiece to be welded is fixed or released relative to the chuck 202.

[0074] The gripper 203 is driven by a pneumatic or servo motor. The gripper 203 is also equipped with a pressure sensor, which is electrically connected to the control module to provide real-time feedback of clamping force data to the control module, thereby preventing deformation of the thin-walled workpiece to be welded.

[0075] The second motor 204 is mounted on the sliding seat 201. The second motor 204 includes an actuating end and an input end. The input end of the second motor 204 is electrically connected to the power supply and the control module. The actuating end of the second motor 204 is connected to the chuck 202. The actuating end of the second motor 204 is used to drive the chuck 202 to rotate relative to the sliding seat 201.

[0076] Reference Appendix Figure 1 , 2 In some embodiments, the slide assembly 300 is disposed between the two clamping assemblies 200. The slide assembly 300 further includes a support member 301, a third motor, a fourth motor, and a sliding member 302. The support member 301 is disposed between the two clamping assemblies 200. The third motor is disposed on the support member 301 and is electrically connected to the control module. The sliding member 302 is connected to the actuating end of the third motor and moves along the second direction on the support member 301 via the third motor. The fourth motor is disposed on the sliding member 302 and is electrically connected to the control module. The actuating end of the fourth motor is connected to the welding torch assembly 400 and is used to drive the welding torch assembly 400 to move along the third direction on the sliding member 302.

[0077] Specifically, the carriage assembly 300 is used to mount the welding torch assembly 400 so that the welding torch assembly 400 can move in a second direction and a third direction.

[0078] The bracket 301 further includes two support parts and one mounting part. The two support parts are fixed at both ends of the mounting part. The two support parts are used to mount the mounting part on the base frame assembly. The mounting part is used to mount the third motor, the fourth motor and the sliding member 302.

[0079] The sliding member 302 is slidably disposed on the mounting part of the bracket member 301, and the sliding member 302 can slide on the bracket member 301 along the second direction.

[0080] The third motor is mounted on the mounting part of the bracket 301. The third motor includes an actuating end and an input end. The input end of the third motor is electrically connected to the power supply and the control module. The actuating end of the third motor is connected to the sliding member 302. The actuating end of the third motor is used to drive the sliding member 302 to slide relative to the bracket 301 in the second direction.

[0081] The fourth motor is mounted on the sliding member 302. The fourth motor includes an actuating end and an input end. The input end of the fourth motor is electrically connected to the power supply and the control module. The actuating end of the fourth motor is connected to the welding torch assembly 400. The actuating end of the fourth motor is used to drive the welding torch assembly 400 to slide relative to the sliding member 302 in a third direction.

[0082] Reference Appendix Figure 1 and Figure 7In some embodiments, the welding torch assembly 400 is rotatably mounted on the slide assembly 300. The welding torch assembly 400 moves in a second direction and a third direction via the slide assembly 300, and the first direction, the second direction, and the third direction are perpendicular to each other. The welding torch assembly 400 further includes a fifth motor 403, a welding torch 401, and a connecting seat 402. The fifth motor 403 is mounted on the slide assembly 300 and is electrically connected to the control module. The fifth motor 403 moves in the second direction and the third direction via the slide assembly 300. The welding torch 401 is connected to the actuating end of the fifth motor 403 and is electrically connected to the control module. The welding torch 401 rotates relative to the slide assembly 300 via the fifth motor 403.

[0083] Specifically, the first direction, the second direction, and the third direction are located on three different planes, and the first direction, the second direction, and the third direction are perpendicular to each other, that is, the three different planes are perpendicular to each other.

[0084] When the clamping assembly 200 moves the workpiece to be welded in the first direction, and the slide assembly 300 moves the welding gun assembly 400 in the second and third directions, the welding gun assembly 400 can be controlled to perform precise welding of the workpiece from all directions without any blind spots.

[0085] In addition, the fifth motor 403 is connected to the actuating end of the fourth motor through a connecting seat 402. The actuating end of the fourth motor drives the fifth motor 403 to move relative to the sliding member 302 in a third direction through the connecting seat 402.

[0086] The fifth motor 403 is fixed on the connecting seat 402. The fifth motor 403 includes an actuating end and an input end. The input end of the fifth motor 403 is electrically connected to the power supply and the control module. The actuating end of the fifth motor 403 is connected to the welding torch 401. The actuating end of the fifth motor 403 is used to drive the welding torch 401 to rotate relative to the connecting seat 402 around a third direction, thereby further improving the welding accuracy of the welding torch 401.

[0087] The welding torch 401 is mounted on the connecting seat 402 and connected to the actuating end of the fifth motor 403. The welding torch 401 is electrically connected to the control module. The welding torch 401 is used to spray a high-temperature flame to weld two relatively independent parts into one component. The welding torch 401 rotates relative to the connecting seat 402 in a third direction via the fifth motor 403, that is, the welding torch 401 rotates relative to the sliding part 302 in a third direction via the fifth motor 403, thereby precisely adjusting the welding position of the welding torch 401 within a small range to improve welding accuracy.

[0088] Reference Appendix Figures 1 to 4 In some embodiments, the image acquisition component 500 is disposed between the two clamping components 200, and the image acquisition component 500 is used to acquire the docking status of the two parts to be welded.

[0089] Specifically, the image acquisition component 500 includes a high-resolution industrial camera and a narrowband filter, which actively filters out strong light interference generated by welding arc through multispectral imaging technology, while capturing visible light and near-infrared images.

[0090] The image acquisition component 500 acquires clear, glare-free weld images in real time during the welding process, accurately identifying the gap, misalignment, and bevel shape at the joint of the two parts to be welded, thus avoiding the problem of ineffective image acquisition due to strong light during the welding process.

[0091] In some embodiments, the welding equipment further includes an infrared ranging sensor, which is located on one side of the welding torch 401 and electrically connected to the control module. The infrared ranging sensor is used to monitor the distance between the nozzle of the welding torch 401 and the workpiece to be welded.

[0092] Specifically, the infrared ranging sensor adopts a pulse infrared ranging sensor, which provides real-time feedback of the distance data between the welding torch 401 nozzle and the workpiece to be welded at a frequency of 1kHz, and drives the carriage assembly 300 to quickly compensate in the third direction through a PID algorithm.

[0093] Infrared ranging sensors are used to maintain a constant welding arc length, eliminate weld penetration fluctuations caused by thermal deformation of the workpiece or vibration of the clamping assembly 200, and improve welding accuracy.

[0094] In some embodiments, the control module is electrically connected to the base assembly 100, the dual clamping assembly 200, the carriage assembly 300, the welding torch assembly 400, the infrared ranging sensor, and the image acquisition assembly 500.

[0095] Specifically, the control module is used to coordinate the positional relationship between the workpiece to be welded and the welding torch 401, simulate and formulate a welding plan, reduce errors in the welding process, eliminate the need for manual monitoring, improve the safety factor of the welding operation, and ensure welding accuracy.

[0096] The welding process of the welding equipment in this application is as follows:

[0097] In the docking step, the two parts to be welded are fixed on the two clamping components 200 respectively. The clamping components 200 drive the grippers 203 through pneumatic or servo motors to ensure that the workpiece does not slip or deviate. Based on the built-in pressure sensor, the clamping components 200 feed back the clamping force data to the control module in real time to prevent the thin-walled parts to be welded from deforming.

[0098] The control module drives the two clamping components 200 to move on the base component 100 along the first direction or the opposite direction via the first motor 103, so that the two parts to be welded approach each other at a preset speed to the docking preparation position.

[0099] The image acquisition component 500 captures the gap, misalignment, and bevel angle of the docking area, generates image data of the docking preparation position, and sends the image data to the control module.

[0100] The control module calculates the displacement and rotation angle that the clamping component 200 needs to be adjusted based on the image data, and drives the clamping component 200 to perform fine-tuning through the second motor 204 to correct the docking posture of the two parts to be welded.

[0101] The simulated welding process involves the control module combining the corrected docking posture with 3D point cloud data to generate a preset welding trajectory through B-spline curve interpolation. The welding trajectory includes the welding start point, welding end point, spatial coordinates of the welding torch 401, moving speed, and oscillation parameters.

[0102] The welding torch assembly 400 runs along a preset trajectory, while the two clamping assemblies 200 move the two workpieces to be welded in sync. At the same time, the infrared ranging sensor monitors the real-time distance between the nozzle of the welding torch 401 and the workpiece at a preset frequency and sends the real-time ranging data to the control module.

[0103] The control module performs differential comparison between the real-time ranging data and the theoretical value of the preset trajectory. If the error of multiple consecutive sampling points exceeds the preset error, it is determined that the trajectory does not match. At this time, an alarm is triggered and the system automatically reverts to the docking step to re-collect weld joint data and correct the trajectory. If the error of the sampling points does not exceed the preset error, the actual welding step is entered.

[0104] In the actual welding process, the control module uses the image acquisition component 500 and encoder data to drive the welding gun component 400 and clamping component 200 to accurately reset to the simulated welding starting point.

[0105] The welding torch 401 ignites an arc with a preset current, while the two clamping components 200 move in tandem according to the trajectory speed; the infrared ranging sensor provides real-time feedback of the distance, the control module calculates and fine-tunes the height of the welding torch 401, and adjusts the workpiece tilt angle through the clamping components 200; the image acquisition component 500 monitors the width of the molten pool, thereby enabling dynamic adjustment of the welding speed.

[0106] After welding is completed, the control module releases the pressure of the clamping assembly 200, and the workpiece is removed by the conveyor belt or robotic arm, while the welding parameters are recorded to the database. Specific Implementation Example 2

[0108] This application also provides a welding device, wherein the specific arrangement of the base assembly 100 is different from that in the first embodiment, while the other structures are the same as in the first embodiment, and therefore will not be described again.

[0109] The base assembly 100 includes a first motor 103 and a transmission component 102. The transmission component 102 has two opposite external threads. The transmission component 102 is threadedly connected to the two clamping components 200 through the two opposite external threads. When the actuating end of the first motor 103 drives the transmission component 102 to rotate, the two clamping components 200 slide simultaneously in a direction that moves closer to each other or further away from each other.

[0110] Specifically, the transmission component 102 is provided with two opposite external threads, and the transmission component 102 is threadedly connected to the two clamping components 200 through the two opposite external threads respectively.

[0111] When the first motor 103 drives the transmission component 102 to rotate, based on the different rotation directions of the two threads on the transmission component 102, the two clamping components 200 that are threadedly connected to the transmission component 102 move in opposite directions. That is, if one clamping component 200 moves along the first direction, the other clamping component 200 moves in the opposite direction of the first direction, thereby achieving the effect of making the two clamping components 200 slide towards each other or away from each other at the same time.

[0112] By controlling the simultaneous movement of the two clamping assemblies 200 through a first motor 103 and a transmission component 102, the two parts to be welded on the two clamping assemblies 200 can be driven to quickly move closer or further apart, which improves welding efficiency and saves the manufacturing cost of welding equipment.

[0113] In some embodiments, the carriage assembly 300 is fixed at an intermediate position between the two clamping assemblies 200 so that the distances from the two clamping assemblies 200 to the carriage assembly 300 are equal.

[0114] Specifically, the welding torch assembly 400 is rotatably mounted on the carriage assembly 300. Therefore, the two parts to be welded held on the two clamping assemblies 200 need to be moved to the position of the carriage assembly 300 to align, so that the welding torch assembly 400 can perform subsequent welding operations.

[0115] By fixing the carriage assembly 300 at the middle position between the two clamping assemblies 200, the two clamping assemblies 200 slide towards each other simultaneously based on the transmission member 102 in preparation for docking. During this process, the docking position of the two parts to be welded is close to the carriage assembly 300, which facilitates the rotation of the welding gun assembly 400 on the carriage assembly 300 for welding.

[0116] By fixing the carriage assembly 300 in the middle position between the two clamping assemblies 200, the position of the carriage assembly 300 is not adjusted after the two parts to be welded are joined, thus further improving the welding efficiency.

[0117] This application provides a welding device. The control module aligns the welding joints of two parts to be welded by controlling the base assembly 100 and the two clamping assemblies 200, thereby improving the welding efficiency. Furthermore, the image acquisition assembly 500, welding torch assembly 400, and slide assembly 300 control the welding torch 401 to move to one side of the welding joint for precise automatic welding without manual monitoring, thus improving the safety factor of the welding operation and ensuring welding accuracy. The asynchronous movement of the two clamping assemblies 200 is controlled by the cooperation of two first motors 103 and two transmission components 102, which facilitates the adjustment of the distance between the two parts to be welded. The precise alignment of the welding joints of the two parts to be welded is achieved by the cooperation of the sliding seat 201, the second motor 204, the chuck 202, and the grippers 203.

[0118] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0119] The above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this application or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of this application, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in this application.
