Description

Technical Field

[0001] The invention relates to the field of welding robots, in particular to an industrial intelligent welding robot with positioning and fixing functions. Background Art

[0002] Welding robot: A welding robot is an industrial robot engaged in welding (including cutting and spraying). According to the definition of the International Organization for Standardization, industrial robots belong to standard welding robots. Industrial robots are multi-purpose, reprogrammable automatic control operating machines. In order to adapt to different uses, the mechanical interface of the robot's last axis is usually a connecting flange, which can be connected to different tools or end effectors. The welding robot is an industrial robot with welding tongs or welding (cutting) guns installed on the end axis flange, so that it can perform welding, cutting or thermal spraying.

[0003] The Chinese patent with announcement number CN215432265 U provides an industrial intelligent welding robot with positioning and fixing functions. The clamping plate and the anti-skid pad are driven to move toward each other by the guide block. When the side surfaces of the two sets of anti-skid pads are in close contact with the outer walls of the two sets of steel parts and the two sets of steel parts to be welded are clamped, the knob is stopped and the handle is turned, thereby completing the clamping of the two sets of steel parts to be welded. The two sets of threaded rods move the slider along the surface of the slide groove, and the slider drives the connection part and the welding robot body to move, so that the welding end of the welding robot body moves horizontally and completes the welding of the two sets of steel parts, thereby completing the welding operation of the two sets of steel parts.

[0004] To sum up, the above structure completes the welding of its workpiece through the cooperation of the clamping plate and the slider during operation. During the actual welding process, the staff needs to clean the outer surface of the workpiece to ensure the subsequent welding quality. The common cleaning is through ultrasonic cleaning. After cleaning, it is necessary to wait for the surface of the workpiece to be completely dry before welding. This process greatly reduces the overall welding efficiency, and a large amount of welding slag will be generated during the welding process. The welding slag is difficult to remove after it is completely cooled, and the subsequent cleaning is too wasteful of overall manpower and material resources. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide an industrial intelligent welding robot with positioning and fixing functions to solve the technical problem that it is necessary to wait for the workpiece surface to be completely dry after cleaning, which greatly reduces the overall welding efficiency and the subsequent cleaning of welding slag wastes too much manpower and material resources.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an industrial intelligent welding robot with positioning and fixing functions, comprising a feeding table, a feeding mechanism is rotatably arranged on the inner side of the feeding table, a frame is arranged on the top of the feeding table, and an ultrasonic cleaning mechanism is installed on the other side thereof, a drying box is installed between the frame and the ultrasonic cleaning mechanism, a clamping mechanism is installed on the inner side of the frame, a sliding plate is slidably arranged on the inner side of the frame, and a gear rod cooperating with the sliding plate is slidably arranged in the interlayer of the frame in the vertical direction, a fixed gear is meshed on one side of the gear rod in the frame, and the One side of the fixed gear is rotatably connected to a bidirectional threaded rod through the meshing engagement with the bevel gear by a transmission mechanism, and the other end of the bidirectional threaded rod penetrates into the interior of the ultrasonic cleaning mechanism, and a placement plate that cooperates with the bidirectional threaded rod is slidably arranged in the vertical direction in the ultrasonic cleaning mechanism, a welding assembly is slidably arranged at the bottom of the sliding plate, and an integrated vacuum cleaner is installed on one side of the welding assembly, one end of the integrated vacuum cleaner is connected to an air pipe, and the other end of the air pipe penetrates into a drying box, an arc-shaped filter plate is installed in the drying box, and a welding slag collection box is provided on the side wall of the arc-shaped filter plate.

[0007] By adopting the above technical solution, the bidirectional threaded rod in the ultrasonic cleaning mechanism is driven to rotate under the action of the meshing of the transmission mechanism and the bevel gear, so that the workpiece to be welded can be cleaned during the welding process, and the welding slag and high-temperature gas at the welding point are sucked into the air pipe through the integrated vacuum cleaner. The welding slag will be discharged into the welding slag collection boxes on both sides under the action of the arc filter plate. At the same time, the high-temperature gas will increase the overall diffusion area under the action of the arc filter plate. At this time, the cleaned workpiece located at the through hole is quickly dried under the action of the high-temperature gas.

[0008] The present invention is further configured such that an elastic component is provided on the inner wall of the drying box, and an arc filter plate is connected to the other end of the elastic component, a bracket is fixedly installed on the top of the arc filter plate, and a plug rod cooperating with the arc filter plate is provided at the bottom of the bracket.

[0009] By adopting the above technical solution, when high-temperature gas is blown to the arc filter plate through the air pipe, the arc filter plate itself will move to the bottom. At this time, the insertion rod will slide out of the filter holes of the arc filter plate. After subsequent drying is completed, the insertion rod will be reinserted into the filter holes of the arc filter plate under the resetting action of the elastic component. In this process, the filter holes of the arc filter plate will be cleaned every time the welding slag is collected, which effectively prevents the arc filter plate from being blocked for a long time.

[0010] The present invention is further configured such that the welding assembly includes a bellows, a welding plate and a welding head, the integrated vacuum cleaner is connected to the air pipe via the bellows, a welding plate is slidably provided at the bottom of the sliding plate, and a welding head is provided at the bottom end of the welding plate on one side of the integrated vacuum cleaner.

[0011] By adopting the above technical solution, in the process of the welding plate driving the welding head and the integrated vacuum cleaner to slide back and forth, the setting of the bellows is convenient for ensuring the airtightness of the connection at both ends of the air pipe to prevent air leakage, and the integrated vacuum cleaner is located on one side of the welding head to effectively absorb the high-temperature welding slag during the welding process.

[0012] The present invention is further configured such that a sliding groove is provided on the inner wall of the frame, and sliding blocks cooperating with the sliding groove are connected to both ends of the sliding plate, and one side of the sliding block is connected to the gear rod.

[0013] By adopting the above technical solution, the stability of the sliding plate sliding on the inner wall of the frame is achieved through the cooperation of the slide groove and the slider, thereby ensuring the stability of the welding assembly during operation. At the same time, the slider will also drive the gear rod at one end to move downward during the sliding process in the slide groove.

[0014] The present invention is further configured such that one end of the fixed gear is connected to a transmission mechanism, and the other end of the transmission mechanism is connected to a positive bevel gear, one side of the positive bevel gear is meshed with a side bevel gear, and one end of the side bevel gear is connected to a bidirectional threaded rod.

[0015] By adopting the above technical solution, when the gear rod drives the fixed gear to rotate, the positive bevel gear at the other end is driven to rotate under the action of the transmission mechanism, and the bidirectional threaded rod is rotated by the meshing of the positive bevel gear and the side bevel gear.

[0016] The present invention is further configured such that the outer wall of the bidirectional threaded rod is symmetrically provided with threaded sleeves, and a support rod is hinged on the top of the threaded sleeve, and the other end of the support rod is hinged to the bottom of the placement plate.

[0017] By adopting the above technical solution, during the rotation of the bidirectional threaded rod, the two sets of threaded sleeves on the outer wall will slide symmetrically in opposite directions. Since the top of the threaded sleeve is hinged with a support rod, the support rod will drive the top placement plate to slide up and down in the ultrasonic cleaning mechanism.

[0018] The present invention is further configured such that a cylinder is provided on the top of the frame, and an output end of the cylinder penetrates the frame and is connected to a sliding plate.

[0019] By adopting the above technical solution, it is convenient for the staff to control the working time of the welding assembly under the action of the cylinder, thereby ensuring the stability of the welding assembly sliding on the inner wall of the frame.

[0020] The present invention is further configured such that a feeding motor is provided on one side of the feeding platform, and the feeding motor is used to drive the feeding mechanism at the output end to rotate.

[0021] By adopting the above technical solution, the workpiece on the feeding mechanism is moved stably and orderly under the action of the feeding motor, further improving the stability of the overall welding.

[0022] The present invention is further configured such that a push plate is provided on the top of the feeding platform for transverse sliding at the ultrasonic cleaning mechanism.

[0023] By adopting the above technical solution, after the ultrasonic cleaning mechanism finishes cleaning the workpiece, the workpiece is pushed onto the feeding mechanism by the action of the push plate.

[0024] The present invention is further configured such that an array of cleaning holes is provided on the top of the placement plate, and the tops of the cleaning holes are provided in an open shape.

[0025] By adopting the above technical solution, when the placement plate slides upward to lift the workpiece, the cleaning agent in the ultrasonic cleaning mechanism will flow downward along the cleaning hole, preventing the cleaning agent from splashing during the subsequent pushing process of the push plate. The open setting prevents the cleaning hole itself from being blocked, and at the same time speeds up the flow of the cleaning agent to the bottom.

[0026] In summary, the present invention mainly has the following beneficial effects:

[0027] 1. The present invention moves the workpiece to the bottom of the frame under the action of the gift-giving mechanism, and then limits and fixes it through the clamping mechanism. Under the action of the cylinder, the sliding plate drives the welding assembly to move downward. At this time, the gear rod on one side of the sliding plate drives the fixed gear to rotate, and the two-way threaded rod in the ultrasonic cleaning mechanism is driven to rotate under the action of the meshing of the transmission mechanism and the bevel gear. In this process, the workpiece to be welded on the placement plate will move downward into the ultrasonic cleaning mechanism through the placement plate, so that the workpiece to be welded can be cleaned during the welding process, thereby accelerating the overall processing efficiency;

[0028] 2. The present invention installs an integrated vacuum cleaner on one side of the welding assembly, and one end of the integrated vacuum cleaner is connected to the drying box through an air pipe. During the welding process, the welding slag is in a high temperature state and is relatively loose. The welding slag and the high-temperature gas at the welding point are sucked into the air pipe through the integrated vacuum cleaner. The arc filter plate is arranged inside the drying box, and the welding slag is discharged into the side wall welding slag collection box under the action of the arc filter plate. In this process, the subsequent cleaning burden of the welding slag is greatly reduced. At the same time, the high-temperature gas increases the overall diffusion area under the action of the arc filter plate. At this time, the workpiece cleaned at the through hole is quickly dried under the action of the high-temperature gas, thereby accelerating the overall welding efficiency;

[0029] 3. The present invention elastically provides a bracket at the top of the arc filter plate in the drying box, and the bracket itself is a single rod setting. When the high-temperature gas is blown to the arc filter plate through the air pipe, the arc filter plate itself will move to the bottom. At this time, the insertion rod slides out of the filter holes of the arc filter plate. After subsequent drying is completed, the insertion rod is reinserted into the filter holes of the arc filter plate under the resetting action of the elastic component. In this process, the filter holes of the arc filter plate are cleaned every time the welding slag is collected, which effectively prevents the arc filter plate from being blocked for a long time.

DETAILED DESCRIPTION

[0041] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] The following describes an embodiment of the present invention based on its overall structure.

[0043] Embodiment 1

[0044] An industrial intelligent welding robot with positioning and fixing functions, such as Figure 1-Figure 9 As shown, it includes a feeding table 1, a frame 2, an ultrasonic cleaning mechanism 4, a drying box 3, a filtering mechanism, a welding mechanism and a clamping mechanism 10. A push plate 6 is arranged on the top of the feeding table 1 and is slidably arranged at the ultrasonic cleaning mechanism 4. After the ultrasonic cleaning mechanism 4 finishes cleaning the workpiece, the workpiece is pushed onto the feeding mechanism 27 by the action of the push plate 6. A feeding motor 5 is arranged on one side of the feeding table 1. The feeding motor 5 is used to drive the feeding mechanism 27 at the output end to rotate. The cleaned and dried workpiece is moved to the bottom of the frame 2 by the action of the feeding mechanism 27, and the workpiece is limitedly clamped by the clamping mechanism 10. Then, the workpiece to be welded is placed on the placing plate 13 at the top of the ultrasonic cleaning mechanism 4. Then, the cylinder 8 at the top of the frame 2 is started. Under the action of the cylinder 8, the sliding plate 9 is driven to slide to the bottom of the frame. A slide groove 24 is provided on the inner wall of the frame 2, and sliders 25 cooperating with the slide groove 24 are connected to both ends of the sliding plate 9.

[0045] One side of the slider 25 is connected to the gear rod 20, and the stability of the sliding plate 9 sliding on the inner wall of the frame 2 is achieved through the cooperation of the slide groove 24 and the slider 25, thereby ensuring the stability of the welding assembly 11 during operation. At the same time, the slider 25 will also drive the gear rod 20 at one end to move downward during the sliding process in the slide groove 24, and the transmission mechanism 12 is connected to one end of the fixed gear 19, and the positive bevel gear 15 is connected to the other end of the transmission mechanism 12. A side bevel gear 14 is meshed on one side of the positive bevel gear 15, and one end of the side bevel gear 14 is connected to the bidirectional threaded rod 18, which drives the fixed gear 19 during the downward sliding process of the gear rod 20 When rotating, the positive bevel gear 15 at the other end is driven to rotate by the action of the transmission mechanism 12, and the two-way threaded rod 18 is rotated by the meshing of the positive bevel gear 15 and the side bevel gear 14, and the other end of the two-way threaded rod 18 penetrates into the interior of the ultrasonic cleaning mechanism 4, and a placement plate 13 cooperating with the two-way threaded rod 18 is provided in the ultrasonic cleaning mechanism 4 for sliding in the vertical direction. In the process of the cylinder 8 driving the sliding plate to move downward, the placement plate 13 drives the top workpiece to be cleaned to move into the interior of the ultrasonic cleaning mechanism 4, so that the workpiece to be welded can be cleaned during the welding process, thereby speeding up the overall processing efficiency;

[0046] At the same time, a welding assembly 11 is slidably provided at the bottom of the sliding plate 9, and an integrated vacuum cleaner 29 is installed on one side of the welding assembly 11. During the welding process, the welding slag is in a high temperature state, making it relatively loose. The welding slag and the high-temperature gas at the welding point are sucked into the air pipe 7 through the integrated vacuum cleaner 29, and the other end of the air pipe 7 passes through the drying box 3. An arc filter plate 23 is installed in the drying box 3, and a welding slag collection box 21 is provided on the side wall of the arc filter plate 23. The welding slag will be discharged into the side wall welding slag collection box 21 under the action of the arc filter plate 23, which greatly reduces the subsequent cleaning burden of the welding slag. At the same time, the high-temperature gas will increase the overall diffusion area under the action of the arc filter plate 23. At this time, the workpiece cleaned at the through hole 22 is quickly dried under the action of the high-temperature gas, thereby accelerating the overall welding efficiency. The above-mentioned work process is repeated to achieve rapid welding processing.

[0047] See also Fig. 9The welding assembly 11 includes a bellows 1101, a welding plate 1102 and a welding head 1103, wherein the integrated vacuum cleaner 29 is connected to the air pipe 7 through the bellows 1101, a welding plate 1102 is slidably arranged at the bottom of the sliding plate 9, and a welding head 1103 is arranged at the bottom end of the welding plate 1102 and on one side of the integrated vacuum cleaner 29. In the process of the welding plate 1102 driving the welding head 1103 and the integrated vacuum cleaner 29 to slide back and forth, the setting of the bellows 1101 is convenient for ensuring the airtightness of the connection at both ends of the air pipe 7 to prevent air leakage, and the integrated vacuum cleaner 29 is located on one side of the welding head 1103, which is convenient for effectively absorbing and treating the high-temperature welding slag during the welding process.

[0048] See also Figure 5 , wherein the outer wall of the bidirectional threaded rod 18 is symmetrically provided with a threaded sleeve 17, and a support rod 16 is hinged at the top of the threaded sleeve 17, and the other end of the support rod 16 is hinged to the bottom of the placement plate 13. During the rotation of the bidirectional threaded rod 18, the two groups of threaded sleeves 17 on the outer wall will slide symmetrically in opposite directions. Since the top of the threaded sleeve 17 is hinged with the support rod 16, the support rod 16 will drive the top placement plate 13 to slide up and down in the ultrasonic cleaning mechanism 4.

[0049] Embodiment 2

[0050] like Fig.10 An industrial intelligent welding robot with a positioning and fixing function is shown, and its overall structure is similar to that of the first embodiment, wherein an elastic component is provided on the inner wall of the drying box 3, and an arc-shaped filter plate 23 is connected to the other end of the elastic component, a bracket 28 is fixedly installed on the top of the arc-shaped filter plate 23, and a plug 26 cooperating with the arc-shaped filter plate 23 is provided at the bottom of the bracket 28. When high-temperature gas is blown to the arc-shaped filter plate 23 through the air pipe 7, the arc-shaped filter plate 23 itself will move to the bottom, and at this time the plug 26 slides out of the filter holes of the arc-shaped filter plate 23. After subsequent drying is completed, the plug 26 is reinserted into the filter holes of the arc-shaped filter plate 23 under the resetting action of the elastic component. In this process, the filter holes of the arc-shaped filter plate 23 are cleaned each time the welding slag is collected, which effectively prevents the arc-shaped filter plate from being blocked for a long time.

[0051] The working principle of the present invention is as follows: when in use, the dried workpiece is conveyed to the bottom of the frame 2 through the feeding mechanism 27, and the staff places the new workpiece to be welded on the top of the placement plate 13, and then starts the cylinder 8 on the top of the frame 2, so that the welding assembly 11 slides downward. In this process, the fixed gear 19 is driven to rotate under the action of the gear rod 20, and the placement plate 13 on the ultrasonic cleaning mechanism 4 is driven to move downward under the meshing of the transmission mechanism 12 and the bevel gear. After moving to the specified position, the welding assembly 11 welds its workpiece, and the ultrasonic cleaning mechanism 4 cleans the workpiece on the placement plate 13, thereby speeding up the overall processing efficiency.

[0052] During the welding process of the welding assembly 11, the welding slag and high-temperature gas at the welding point are extracted through the action of the integrated vacuum cleaner 29, which effectively prevents the welding slag from being subsequently fixed on the weld of the workpiece, greatly reducing the burden of cleaning the subsequent welding slag, and then discharged into the drying box 3 through the action of the air pipe 7. Under the action of the arc filter plate 23 in the drying box 3, the welding slag is discharged into the welding slag collection box 21 on the side wall. At the same time, under the action of the arc filter plate 23, the downward spraying area of ​​the high-temperature gas is expanded, so that the workpiece cleaned at the through hole 22 is quickly dried, and the overall welding efficiency is accelerated in this process.

[0053] Although an embodiment of the present invention has been shown and described, this specific embodiment is only an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
