Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to an online vision high-frequency pulse hot press welding machine. Background Technology

[0002] A high-frequency pulse hot press welding machine is a device that uses the heat energy instantaneously generated by a high-frequency pulse current to heat and pressurize the welding materials, thereby achieving material bonding. By precisely controlling the parameters of the pulse current, this equipment can complete the welding process quickly and efficiently, offering advantages such as high welding quality, a small heat-affected zone, and fast welding speed. It is widely used in various fields such as electronics, new energy, and precision instruments, providing reliable technical support for the welding of various precision components and thin sheet materials.

[0003] However, there are still many shortcomings in existing high-frequency pulse hot pressing welding applications: On the one hand, traditional welding equipment uses manual loading and unloading, which is inefficient and cannot meet the needs of large-scale industrial production. Manual operation is also prone to errors, resulting in poor product consistency and increased defect rate. On the other hand, during the welding process, for complex welding trajectories, operators usually need to manually adjust them online. This not only requires high skill from the operators, but also has limited precision, which cannot guarantee the accuracy and stability of the welding trajectory, seriously affecting welding quality and production efficiency, while also posing operational safety hazards.

[0004] To address the aforementioned technical deficiencies, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an online vision high-frequency pulse hot press welding machine to solve the problems mentioned above.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an online vision high-frequency pulse hot press welding machine, comprising a protective housing, wherein a control panel is provided at the corner of the outer wall of one end of the protective housing, and a support frame is symmetrically provided on the inner walls of both sides of the protective housing. A track feed mounting frame penetrating the protective housing is provided inside one end of the support frame. A visible cover plate is hinged to the top of one end of the protective housing. Slides are symmetrically provided at the bottom of both sides of the track feed mounting frame. An adjustment drive frame cooperating with the slides is provided at the bottom of the end of the track feed mounting frame away from the visible cover plate. The adjustment drive frame includes an adjustment motor and a slide table. A servo motor and several sets of vision sensors are symmetrically provided at the bottom of one side of the track feed mounting frame.

[0007] A hot-welding frame is provided at the top of the end of the support frame away from the track feed mounting frame. The hot-welding frame includes a truss beam and a track frame. A hot-welding mechanism is provided at the end of the truss beam near the track feed mounting frame. The hot-welding mechanism includes a movable frame and a hot-welding sleeve. A re-inspection sensor is provided above the side of the hot-welding sleeve.

[0008] Furthermore, several sets of metal brackets are provided on the bottom inner wall of the protective box, and several sets of cooling fans for air circulation are symmetrically arranged on the bottom walls of both sides of the protective box. Telescopic hydraulic rods that are sleeved with the inner wall of the protective box are provided on the inner walls of both sides of the visible cover, and a ventilation hole is sleeved in the center of the top wall of the protective box.

[0009] Furthermore, a rectangular groove is provided through the middle of both ends of the support frame, and the support frame is composed of two sets of side-by-side splicing, with an anti-fall plate located between multiple sets of sliding platforms between the two sets of support frames.

[0010] Furthermore, the bottom of the inner wall of the track feeding frame is provided with a drive pulley that is sleeved with a servo motor. The top wall of the inner wall of the track feeding frame is sleeved with several sets of guide wheels that cooperate with the drive pulley for transmission. A replaceable conveyor belt is provided between the guide wheels and the drive pulley. The bottom of the inner wall of the track feeding frame is provided with several sets of lifting cylinders. The top of the lifting cylinders is provided with a rotary cylinder. The top of the rotary cylinder is sleeved with an adjustment plate. The top of the track feeding frame is provided with several sets of air suction pads close to the adjustment plate.

[0011] Furthermore, a lead screw is mounted above the slide table, and a detachable synchronous belt drive is provided between the lead screw and the adjustment motor. Limiting guides that are connected to the slide table cross-section are provided at both ends of the lead screw.

[0012] Furthermore, the bottom of both sides of the truss beam is provided with a track frame that is connected to the top of the support frame, the top of one side of the truss beam is provided with a first drag chain that is connected to the inner wall of the protective box, and the end of the truss beam away from the visible cover is provided with a second drag chain that is connected to the inner wall of the protective box. The first drag chain and the second drag chain are staggered vertically and arranged vertically.

[0013] Furthermore, a hot welding module is fitted at the bottom of the hot welding sleeve, a hot pressure cylinder is fitted at the top of the hot welding sleeve, a fixed plate that is connected to the truss beam is fitted at the other end of the movable frame, and multiple sets of fine adjustment cylinders are slidably fitted at one end of the movable frame. The fine adjustment cylinders are cylinder one and cylinder two, and cylinder one and cylinder two are respectively connected to the hot pressure cylinder and the re-inspection sensor.

[0014] Furthermore, the control panel includes a hot-welding acquisition module for real-time acquisition of workpiece transport data and dynamic welding data during the use of the hot-press welding machine. The transport data and dynamic welding data are tagged based on timestamps and acquisition points to build a new source cache library.

[0015] The component loading dynamic analysis module obtains the loading data in the new source cache library and the welding process reference value in the historical database, analyzes and generates abnormal loading status signals and sends them to the time welding decision control module;

[0016] Joint Welding Surface Risk Module: It compares and analyzes the dynamic welding data in the new source cache library with the reference values ​​of welding samples in the historical database, generates welding judgment results, and combines them with the abnormal signal of the carrying status to trigger the hot welding abnormal signal. The welding judgment results and the hot welding abnormal signal are sent to the welding decision control module.

[0017] Upon receiving abnormal signals from the operating status, welding judgment results, and hot welding anomaly signals, the time-based welding decision control module sequentially triggers the corresponding decision plans and generates corresponding operation instructions based on the decision plans to control the hot-press welding machine and remind supervisory personnel.

[0018] The beneficial effects of this invention are:

[0019] 1. This invention replaces the traditional manual loading and unloading mode by connecting the track feeding frame and the feeding conveyor belt, realizing automatic workpiece transfer and positioning, which greatly improves production efficiency and avoids the defect rate fluctuation caused by manual operation. Based on the coordinated operation of vision sensor and adjustment drive frame, workpiece carrying data can be collected in real time and the welding trajectory can be automatically adjusted. The active pulley and guide wheel are driven by servo motor, and the lifting cylinder and rotary cylinder are used to perform three-dimensional posture calibration of workpiece, so that the welding accuracy of complex trajectory can be effectively controlled, and the problem of insufficient accuracy of manual adjustment can be completely solved.

[0020] 2. This invention integrates a hot welding acquisition module and a multi-dimensional analysis module on the control panel. It can build a dynamic data cache based on timestamps and acquisition points, and compare historical welding samples with current process parameters in real time. When the workpiece dynamic analysis module detects that the workpiece transport deviation exceeds the tolerance, it automatically triggers the servo motor to reduce speed and the adjustment plate to straighten the mechanism. The joint weld surface risk module analyzes the surface state before and after welding through re-inspection sensors. If the welding quality is found to exceed the sample fluctuation limit threshold, it immediately links the hot pressing cylinder and the fine-tuning cylinder to correct the process parameters, which greatly improves the welding qualification rate.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figure 1 - Figure 10 As shown, this embodiment is an online vision high-frequency pulse hot press welding machine, including a protective housing 1, and a control panel 2 is provided at the corner of the outer wall of one end of the protective housing 1. Support frames 5 are symmetrically arranged on the inner walls of both sides of the protective housing 1. A track feed mounting frame 3 that penetrates the protective housing 1 is provided inside one end of the support frame 5. A viewing cover 102 is hinged to the top of one end of the protective housing 1. Slides 308 are symmetrically arranged at the bottom of both sides of the track feed mounting frame 3. At the bottom of the end of the track feed mounting frame 3 away from the viewing cover 102, there is an adjustment drive frame 6 that cooperates with the slide 308. The adjustment drive frame 6 includes an adjustment motor 601 and a slide table 604. A servo motor 301 and several sets of vision sensors 303 are symmetrically arranged at the bottom of one side of the track feed mounting frame 3.

[0036] The protective housing 1 is equipped with fixed legs and casters on the metal support at the bottom. The casters are used to move it to the workpiece production line docking area. The fixed legs are then deployed to fix the protective housing 1 in this area, forming a complete automatic workpiece welding production line when spliced ​​with the workpiece production line. It should be noted that the workpiece production line includes a feeding conveyor belt and a return conveyor belt, which are located on both sides of the protective housing 1 and work in conjunction with the track feed frame 3 to replace the traditional manual feeding step and achieve efficient processing of workpiece hot pressing welding.

[0037] Several sets of metal brackets are provided on the bottom inner wall of the protective box 1. Several sets of cooling fans 101 for air circulation are symmetrically provided on the bottom walls of both sides of the protective box 1. Telescopic hydraulic rods 103 that are sleeved with the inner wall of the protective box 1 are provided on the inner walls of both sides of the visible cover 102. A ventilation hole is sleeved in the center of the top wall of the protective box 1.

[0038] Example 2: This example is an online vision high-frequency pulse hot press welding machine, including a support frame 5 with a hot welding frame 4 at the top of the end away from the track feed frame 3. The hot welding frame 4 includes a truss beam 401 and a track frame 402. A hot welding mechanism 7 is provided at the end of the truss beam 401 near the track feed frame 3. The hot welding mechanism 7 includes a movable frame 701 and a hot welding sleeve 705. A re-inspection sensor 704 is provided on the upper side of the hot welding sleeve 705.

[0039] A rectangular groove is provided through the middle of both ends of the support frame 5. The support frame 5 is composed of two sets of side-by-side splicing. An anti-fall plate is provided between the two sets of support frames 5 and located between multiple sets of slides 604.

[0040] The bottom of the inner wall of the track feed mounting frame 3 is provided with a drive pulley that is sleeved with the servo motor 301. The top wall of the inner wall of the track feed mounting frame 3 is sleeved with several sets of guide wheels 304 that cooperate with the drive pulley for transmission. A replaceable conveyor belt is provided between the guide wheels 304 and the drive pulley. The bottom of the inner wall of the track feed mounting frame 3 is provided with several sets of lifting cylinders 305. The top of the lifting cylinders 305 is provided with a rotary cylinder 306. The top of the rotary cylinder 306 is sleeved with an adjusting plate 307. The top of the track feed mounting frame 3 is provided with several sets of air suction pads 302 close to the adjusting plate 307. The bottom of the slide 308 is provided with a slider that cooperates with the slide table 604. The middle frame of the slide 308 is provided with a threaded hole that is sleeved with the lead screw 603.

[0041] After adjustment, the track feed mounting frame 3 is aligned with the feeding conveyor belt and completes the unloading of some workpieces from the same batch. Under the traction of the adjustment drive frame 6, the batch of workpieces is carried close to the hot welding mechanism 7 and the welding processing area. During this process, several sets of vision sensors 303 installed on the track feed mounting frame 3 work together to collect data on the transport status of the workpieces placed on the track feed mounting frame 3. Some of the data sensors are installed on the inner wall of the top of the rectangular groove of the support frame 5. When the workpiece is transported close to the area of ​​the air suction pad 302 and the adjustment plate 307, the servo motor 301 stops driving the drive pulley to rotate. The replaceable conveyor belt that is sleeved on the surface of the drive pulley and the guide wheel 304 stops running at the same time, thereby keeping the workpiece stationary on the track feed mounting frame 3. The lifting cylinder 305 drives the adjustment plate 307 to slide up until the bottom of the workpieces on the side-by-side replaceable conveyor belts comes into contact, which is used to lift and limit the bottom of the workpieces and to cooperate with the hot welding mechanism 7 to perform hot pressure welding on the top area of ​​the workpieces.

[0042] Based on the workpiece's transport status on the replaceable conveyor belt surface and its lifting status by the adjusting platen 307, adjustments are made in conjunction with the control commands of the hot press welding machine's operating system. Specifically, the lifting cylinder 305 drives the adjusting platen 307 to move up and down, lifting the workpiece and keeping it separated from the replaceable conveyor belt surface. During this process, the rotary cylinder 306 drives the adjusting platen 307 to rotate, adjusting the workpiece. After the adjusting platen 307 returns to its reset position and slides down, the adjusted workpiece is placed back on the replaceable conveyor belt surface. The adjusting platen 307 then lifts and limits the bottom of the adjusted workpiece, ensuring that the fit between the workpiece and the hot press welding mechanism 7 is within the specified range, thereby improving the pass rate of the workpiece after hot press welding.

[0043] A lead screw 603 is mounted above the slide table 604. A detachable synchronous belt drive connects the lead screw 603 to the adjusting motor 601. Limiting guides 602, which mate with the cross-section of the slide table 604, are located at both ends of the lead screw 603. The adjusting drive frame 6 starts operating via the adjusting motor 601, which is connected to the lead screw 603 via the detachable synchronous belt. A pulley, which engages with the detachable synchronous belt, is mounted on the lead screw 603. Figure 5As shown, the lead screw 603 is restricted to the slide table 604 by the positioning guide 602. The lead screw 603 rotates and is connected to the slide 308 by the screw hole thread. According to the rotation direction of the lead screw 603, the slide 308 is driven to move axially along the top of the slide table 604. During this process, the lead screw 603 and the slide 308 cooperate to form a transmission line. The slide 308 makes frictional contact with the surface of the slide table 604 through the slider to form a guide trajectory. Accordingly, the position of the track feed mounting bracket 3 on the support frame 5 can be adjusted according to the rotation direction and speed of the positioning motor 601. After the material is picked up, it is used to cooperate with the hot welding mechanism 7 to perform hot pressure welding on the workpiece.

[0044] The bottom of both sides of the truss beam 401 is provided with a track frame 402 that is connected to the top of the support frame 5. The top of one side of the truss beam 401 is provided with a first drag chain 403 that is connected to the inner wall of the protective box 1. The end of the truss beam 401 away from the visible cover plate 102 is provided with a second drag chain 404 that is connected to the inner wall of the protective box 1. The first drag chain 403 and the second drag chain 404 are staggered vertically and arranged vertically.

[0045] The protective housing 1 is provided with a drive element at one end away from the visible cover 102, which is connected to the first drag chain 403 and the second drag chain 404. The first drag chain 403 is used to pull the truss beam 401 to move axially along the two sets of track frames 402, and to approach and move away from the track feed frame 3. The second drag chain 404 is used to drive the hot welding mechanism 7 to move to both sides along the truss beam 401, and to adjust the hot welding mechanism 7 and the adjusting plate 307 to maintain vertical alignment.

[0046] A welding module 706 is fitted onto the bottom of the welding sleeve 705, and a hot-pressing cylinder 703 is fitted onto the top of the welding sleeve 705. A fixed plate 707, which mates with the truss beam 401, is fitted onto the other end of the movable frame 701. Multiple sets of fine-tuning cylinders 702 are slidably fitted onto one end of the movable frame 701. Each fine-tuning cylinder 702 has two cylinders, Cylinder 1 and Cylinder 2, which are respectively connected to the hot-pressing cylinder 703 and the re-inspection sensor 704. Cylinder 1 and Cylinder 2 are arranged vertically. Figure 8 As shown.

[0047] It should be noted that when the hot welding mechanism 7 presses down close to the top of the workpiece, the bottom edge of the hot welding sleeve 705 of the hot welding mechanism 7 contacts the air suction pad 302. The air suction pad 302 is provided with a vertical cavity and a vertical guide post. After the top of the air suction pad 302 contacts the hot welding sleeve 705, as the hot welding sleeve 705 continues to slide down, it pushes the top pad of the air suction pad 302 down. The vertical cavity is compressed and squeezes the spring inside. The pressure sensor provided in the vertical space is triggered by the pressure and generates a feedback signal to determine whether the hot welding mechanism 7 slides down normally along the preset trajectory and performs hot pressure welding on the workpiece. The adjusting plate 307 is located below the two adjacent sets of air suction pads 302, lifting the workpiece from bottom to top. The two sets of air suction pads 302 located on the track feed frame 3 are close to the two ends of the workpiece. The hot welding mechanism 7 contacts the top of the workpiece from top to bottom to perform hot pressure welding.

[0048] The hot welding mechanism 7 is connected to the truss beam 401 via a fixed plate 707. The movable frame 701 is composed of two sets of plates spliced ​​together, and a propulsion cylinder is set on one side between the two sets of plates. The propulsion cylinder drives the front plate connected to the fine-tuning cylinder 702 to slide down, which is used to initially approach the workpiece. The first cylinder of the fine-tuning cylinder 702 further drives the hot-pressing cylinder 703 to slide down. The hot-pressing cylinder 703 cooperates with the first cylinder of the fine-tuning cylinder 702 to achieve high-precision micro-control adjustment of the hot welding sleeve 705. The hot welding sleeve 705 contacts the air suction pad 302 and is positioned on the hot welding sleeve 705. After the 05 continues to slide down, the hot welding module 706 comes into contact with the workpiece surface and performs high-frequency pulse hot pressing welding on it. After the welding is completed, the hot welding mating frame 4 drives the hot welding mechanism 7 to reset, the adjustment drive frame 6 drives the track feed mating frame 3 to reset, and the track feed mating frame 3 drives the welded workpiece to move to the return material conveyor belt. It should be noted that the second cylinder of the fine adjustment cylinder 702 is used to drive the re-inspection sensor 704 to slide down close to the side of the hot welding sleeve 705, and is used to collect dynamic welding data of the workpiece after the hot welding module 706 has been processed.

[0049] Example 3: Please refer to Figure 11As shown, this embodiment is an online vision high-frequency pulse hot press welding machine. The control panel 2 includes a hot weld acquisition module for real-time acquisition of workpiece transport data and dynamic welding data during the use of the hot press welding machine. When the control panel 2 generates instructions for controlling the operation of the hot press welding machine through human-machine interaction with the supervisor, inspection instructions are generated simultaneously. The inspection instructions are used to control sensors that are connected to the control panel 2 by communication or wires, including vision sensors, re-inspection sensors, and pressure sensors. The welding cycle is constructed from the starting point of the inspection instructions to the temporary endpoint of the last set of data acquisition. The welding cycle is divided equally and a timestamp is constructed for time-marking processing of the acquired data. The sensors are numbered according to their installation positions. Based on this, the data acquired by the numbered sensors is marked with a location to form an acquisition point. The timestamp and the acquisition point mark the data simultaneously for easy traceability and back inspection. The transport data and dynamic welding data are marked based on the timestamp and acquisition point to construct a new source cache library. At the same time, the control panel 2 is internally set with pre-stored historical workpiece processing record data to construct a historical database.

[0050] Based on the batch type of workpieces awaiting hot-press welding, a matching processing scheme pre-stored within the control panel 2 is selected. Through peripherals set outside the control panel 2, including a mouse, keyboard, and monitor, human-machine interaction is performed with the supervisor, thereby adjusting the overall operating status of the hot-press welding machine according to the batch type of the workpieces.

[0051] The component dynamic analysis module obtains the load data from the new source cache library and the welding process reference values ​​from the historical database, analyzes and generates an abnormal load status signal, and sends it to the time-based welding decision control module. The processing procedure for its load data is as follows:

[0052] The transport data is collected by several sets of vision sensors, which are used to record the status data of the workpiece from one side to the other after it is placed on the track feed frame 3. The four corner point data of the workpiece placement are extracted separately from the transport data according to each set of timestamps. The four corner point data include point A (ab / ac), point B (ba / bd), point C (ca / cd), and point D (bc / db). Points A and C are closer to the side of the track feed frame 3, and points B and D are closer to the other side of the track feed frame 3. The workpiece Gi range frame value is constructed by combining the marked area on the replaceable conveyor belt surface where the workpiece is placed. G represents the workpiece, i represents the number of workpieces, and i is a natural number greater than zero. The marked area is a set of equidistant color marks pre-made on the replaceable conveyor belt surface.

[0053] The uniform welding process reference value represents the fluctuation range of historical four-corner point data of historical workpieces within a time stamp, as well as the fluctuation coefficient retrieved from the historical database. The fluctuation coefficient represents the possible sensor detection error and shows the continuous difference between the transport data and the uniform welding process reference value. The middle set of four-corner point data within each time stamp of the transport data is compared with the uniform welding process reference value:

[0054] If there is a difference between the Gi range frame value of the transport data and the reference value of the uniform welding process, and the difference is less than the fluctuation coefficient, or if there is no difference between the Gi range frame value of the transport data and the reference value of the uniform welding process, it indicates that the workpiece transport is normal and no signal is generated.

[0055] If there is a difference between the Gi range frame value of the transport data and the reference value of the welding process, and the difference is greater than or equal to the fluctuation coefficient, an abnormal transport status signal is generated and sent to the time welding decision control module. After receiving the abnormal transport status signal, the time welding decision control module triggers the control plan and immediately controls the servo motor 301 to gradually reduce the speed until the group of workpieces moves to the top of the nearest set of adjustment plates 307. The adjustment plate 307 uses the rotary cylinder 306 and the lifting cylinder 305 in conjunction with the replaceable conveyor belt to adjust the position of the workpiece in a multi-dimensional three-dimensional manner and straighten it so that it can be used in conjunction with the hot welding mechanism 7 for high-precision hot pressure welding.

[0056] The joint weld risk module compares and analyzes the dynamic welding data obtained from the new source cache library with the reference values ​​of welding samples in the historical database to generate a weld judgment result. It then combines the abnormal signal of the operating status to trigger a hot welding abnormal signal. The weld judgment result and the hot welding abnormal signal are sent to the time-based welding decision control module. The specific processing procedure is as follows:

[0057] Dynamic welding data includes surface condition data of the workpiece before hot-press welding collected by re-inspection sensors, and surface condition data of the workpiece after hot-press welding. The welding sample reference value is identified as qualified product sample data of the same type of workpiece processed under the same program of the same hot-press welding machine in history. The welding sample fluctuation range limit threshold is retrieved from the historical database. The welding sample fluctuation limit threshold is represented by the difference between the most standard excellent value and the closest unqualified inferior value in the parameters generated by the welding sample reference value. The dynamic welding data is compared with the welding sample reference value:

[0058] If the dynamic welding data is close to the reference value of the welding sample and does not exceed the inferior value of the welding sample fluctuation limit threshold, it indicates that the welding is normal.

[0059] If there is a significant difference between the dynamic welding data and the welding sample reference value, or if the dynamic welding data is close to the welding sample reference value and exceeds the inferior value of the welding sample fluctuation limit threshold, it indicates a welding abnormality, and a hot welding abnormality signal is generated and sent to the welding decision control module.

[0060] When a hot welding anomaly signal is generated, the joint welding surface risk module retrieves the feedback signal generated by the pressure sensor operation from the control panel 2, as well as the results generated by the component dynamic analysis module. If a feedback signal exists and there is no abnormal operation signal, and the data stream contained in the feedback signal is within the controllable error range of the data generated by the calibration contact between the hot welding sleeve 705 and the air suction pad 302 in the historical database, it indicates that the hot welding mechanism 7 and the air suction pad 302 are operating normally in the hot pressure welding process of the workpiece. If the problem is not a quality issue with the workpiece itself, a hot component re-inspection signal is generated and sent to the welding decision control module. When the welding decision control module receives both a hot welding anomaly signal and a hot component re-inspection signal simultaneously, it triggers a regulatory plan. The regulatory plan generates a stop-work order and sends it to the control panel 2 to stop the hot-press welding of subsequent workpieces. It generates a text message in the style of "workpiece anomaly / transportation normal / welding normal / previous re-inspection" and sends it to the smart device worn by the supervisor during their shift. It also includes relevant data of the generated signal. It should be noted that the controllable error is obtained by training or comparing relevant data in the historical database, and the specific error varies according to the actual historical data and welding processing conditions.

[0061] If no feedback signal is received, it indicates that there is a calibration difference between the hot welding mechanism 7 and the air suction pad 302, generating an internal inspection emergency signal. When the time welding decision control module receives the hot welding abnormality signal and the internal inspection emergency signal, the time welding decision control module immediately generates a pause command and feeds it back to the control panel 2. The control panel 2 immediately stops the welding process of subsequent workpieces, generates "Hot welding mechanism 7 calibration abnormality" and sends it along with relevant data to the smart device carried by the supervisor on duty.

[0062] Combining Embodiments 1, 2, and 3, the track feed assembly 3 connects with the feeding conveyor belt to replace manual loading and unloading, achieving automatic workpiece transfer and positioning, significantly improving production efficiency and avoiding fluctuations in the defect rate caused by manual operation. With the assistance of the vision sensor 303 and the positioning drive frame 6, real-time transport data is collected and the welding trajectory is automatically adjusted. The servo motor 301 and lifting cylinder 305, among other components, perform three-dimensional calibration of the workpiece, effectively controlling the welding accuracy of complex trajectories.
