Description

Technical Field

[0001] This utility model relates to the field of welding torch equipment technology, and in particular to a welding torch cleaning device. Background Technology

[0002] Currently, arc welding robots are widely used in automated production lines in the automotive, shipbuilding, and container industries. The nozzle and contact tip of an arc welding torch are typically threaded onto the torch body. During use, weld slag can easily adhere to the nozzle and contact tip, affecting welding quality; therefore, regular cleaning or nozzle replacement is necessary.

[0003] Currently, the cleaning and replacement of nozzles on the production line are mainly done manually, which results in high labor costs. Utility Model Content

[0038] The third driving member is driven to the other end of the second shear blade and is used to drive that end of the second shear blade to rotate around the hinge point, so that the second shearing cut and the first shearing cut switch between positions that are misaligned or overlapped.

These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0078] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0079] The welding torch cleaning device 10 provided by this utility model is mainly used for cleaning and replacing the nozzle 21 and the conductive tip 22 of the welding torch 20. For example, the welding torch 20 includes a welding torch body and a conductive tip 22 located at the end of the welding torch body, and a nozzle 21 that is threadedly connected to the welding torch body and located outside the conductive tip 22.

[0080] Please see Figure 1 and Figure 2 As shown, the welding torch cleaning device 10 of this embodiment includes a frame 100, a clamping mechanism 200, a turntable mechanism 300, and a lifting mechanism 400, as well as a disassembly and assembly mechanism 500, a nozzle cleaning mechanism 600, a conductive tip cleaning mechanism 700, a wire cutting mechanism 800, and a liquid spraying mechanism 900. The frame 100 serves as the support for each mechanism, primarily used to support and mount them. The clamping mechanism 200 clamps and fixes the welding torch 20 at a predetermined position on the frame 100.

[0081] The turntable mechanism 300 can rotate to switch the positions of the disassembly / assembly mechanism 500 and the conductive tip cleaning mechanism 700, so that the disassembly / assembly mechanism 500 and the conductive tip cleaning mechanism 700 can perform operations such as disassembling and assembling the nozzle 21 of the welding torch 20 and cleaning the conductive tip 22. The lifting mechanism 400 is used to cooperate with the turntable mechanism 300 to switch the relative positions of the disassembly / assembly mechanism 500, the nozzle cleaning mechanism 600, the conductive tip cleaning mechanism 700 and the welding torch 20 components.

[0082] Specifically, the disassembly / assembly mechanism 500 is used to disassemble or install the nozzle 21 of the welding torch 20. The nozzle cleaning mechanism 600 is used to clean the nozzle 21 on the disassembly / assembly mechanism 500. The conductive tip cleaning mechanism 700 is used to clean the conductive tip 22 of the welding torch 20. The wire cutting mechanism 800 is used to cut the welding wire. The liquid spraying mechanism 900 is used to spray anti-spatter liquid onto the nozzle 21 and conductive tip 22 of the welding torch 20.

[0083] The following will describe in detail the specific embodiments of the various parts of the gun cleaning device 10 of this application with reference to the accompanying drawings.

[0084] like Figure 1 and Figure 2 As shown, the frame 100 can be a box-frame structure. For example, the frame 100 may include a top plate 110 and a bottom plate 120, as well as a plurality of support columns 130 disposed between the top plate 110 and the bottom plate 120. An installation space may be formed between the top plate 110 and the bottom plate 120 for mounting the turntable mechanism 300, the lifting mechanism 400, the disassembly and assembly mechanism 500, the nozzle cleaning mechanism 600, and the conductive nozzle cleaning mechanism 700.

[0085] like Figure 1As shown, the frame 100 may also include multiple side panels 140. The multiple side panels 140, together with the top plate 110 and the bottom plate 120, can form a relatively enclosed installation space. This effectively isolates noise and dust and fumes generated during the cleaning process of the welding torch 20.

[0086] The top of the frame 100 is provided with a fixing position for fixing the welding gun 20. Specifically, the top plate 110 may have an opening for inserting the welding gun 20, and the location of this opening is the fixing position for fixing the welding gun 20.

[0087] See Figure 1 As shown in the embodiments of this application, the clamping mechanism 200 can be fixedly installed on the top plate 110 of the frame 100. The clamping mechanism 200 can be arranged at the socket of the top plate 110 mentioned above. The clamping mechanism 200 can clamp and fix the welding torch 20, so that the welding torch 20 is kept fixed in the fixed position.

[0088] like Figure 1 As shown, in one embodiment, the clamping mechanism 200 may include a pneumatic finger 210. The pneumatic finger 210 uses compressed air as power to clamp or grasp a workpiece. The pneumatic finger 210 has the advantages of safe and reliable use, simple structure, and low cost.

[0089] Specifically, the pneumatic finger 210 has two grippers for gripping workpieces. Further, in one embodiment, the clamping mechanism 200 may also include two extension clamps 220, which are detachably connected to the two grippers respectively. By providing the extension clamps 220, the length of the grippers of the pneumatic finger 210 can be extended, thus widening the gripping range of the pneumatic finger 210.

[0090] It is understood that in other embodiments, the clamping mechanism 200 may also be other structures capable of clamping, such as electric grippers, etc.

[0091] In the embodiments of this application, the torch cleaning device 10 includes a clamping mechanism 200 for clamping and fixing the welding torch 20. However, this application is not limited to this; in other embodiments, the clamping mechanism 200 may be omitted from the torch cleaning device 10. When it is necessary to clean the welding torch 20, the welding robot can position and hold the welding torch 20 at a fixed position at the top of the frame 100, depending on the specific situation.

[0092] See Figure 2 As shown in the embodiment of this application, the turntable mechanism 300 is disposed in the installation space below the top plate 110. Specifically, the turntable mechanism 300 includes a fixed base 310, which is movably mounted on the frame 100 via a lifting mechanism 400.

[0093] In one embodiment, the lifting mechanism 400 can be a structure such as a pneumatic cylinder or a hydraulic cylinder. For example, the cylinder body can be fixedly mounted on the base plate 120 of the frame 100, and the end of the piston rod of the cylinder can be fixed to the bottom surface of the fixed seat 310. Thus, the action of the cylinder can drive the fixed seat 310 to move up and down, thereby driving the turntable mechanism 300 to move up and down as a whole.

[0094] It is understood that the lifting mechanism 400 may also include a lifting frame, and the fixed seat 310 is slidably connected to the lifting frame. The lifting frame can provide sliding support for the entire turntable mechanism 300.

[0095] Of course, in other embodiments, the lifting mechanism 400 can also be other structures that can achieve the purpose of lifting, such as a screw lifting device, etc.

[0096] like Figure 2 As shown, the turntable mechanism 300 also includes a turntable 320 disposed above the fixed base 310, and the turntable 320 is rotatably connected to the fixed base 310 in a horizontal direction. For example, the turntable mechanism 300 may include a rotary assembly disposed between the turntable 320 and the fixed base 310. The turntable 320 is rotatably connected to the fixed base 310 via the rotary assembly. Furthermore, the rotary assembly can drive the turntable 320 to rotate. The rotary assembly may be an electric rotary table.

[0097] Alternatively, in other embodiments, the rotating assembly may include a rotating gear and a rotating driver. The rotating gear may be fixed to the bottom of the turntable 320, and the rotating driver may be fixed to the mounting base 310 and driven to rotate the rotating gear, thereby causing the turntable to rotate. This application does not impose specific limitations on this aspect.

[0098] See Figure 2 As shown in the embodiment of this application, the disassembly / assembly mechanism 500 is disposed on the turntable 320. Since the turntable 320 can rotate horizontally, it can drive the disassembly / assembly mechanism 500 on it to rotate horizontally relative to the frame 100. Thus, the disassembly / assembly mechanism 500 can move to a position corresponding vertically to the welding torch 20 at the fixed position as needed, thereby achieving the purpose of disassembling and assembling the nozzle 21 of the welding torch 20.

[0099] For example, see Figures 4 to 6 As shown, the disassembly and assembly mechanism 500 includes a fixed cylinder 510, a clamping assembly 520, and a first drive member 530. The fixed cylinder 510 is rotatably mounted on the turntable 320. For example, the fixed cylinder 510 may be a cylindrical structure. The top end of the fixed cylinder 510 may be an opening for insertion of the end of the welding torch 20.

[0100] A clamping assembly 520 is mounted on the fixed cylinder 510 and is used to clamp or release the nozzle 21 of the welding torch 20. A first driving member 530 is fixedly mounted on the turntable 320 and is drivenly connected to the fixed cylinder 510. The first driving member 530 is used to drive the fixed cylinder 510 to rotate. The first driving member 530 can be a motor, which can drive the fixed cylinder 510 to rotate via a gear set. For example, a driving gear can be fixedly mounted on the output shaft of the motor, and a driven gear can be fixedly connected to the bottom end of the fixed cylinder 510, with the driven gear meshing with the driving gear. Therefore, the motor can drive the driven gear to rotate via the driving gear, thereby driving the fixed cylinder 510 to rotate.

[0101] In this embodiment, when the disassembly and assembly mechanism 500 is in use, the end of the welding torch 20 is inserted into the fixed cylinder 510, and the clamping assembly 520 clamps the nozzle 21. Then, the first driving member 530 drives the fixed cylinder 510 to rotate, which drives the nozzle 21 to rotate and achieves the purpose of disassembling the nozzle 21.

[0102] The clamping assembly 520 can clamp or release the nozzle 21 in various ways. For example... Figure 5 As shown, in one embodiment, the disassembly and assembly mechanism 500 further includes a sliding cylinder 540, which is slidably disposed inside the fixed cylinder 510. The clamping assembly 520 includes a plurality of clamping blocks 521, each clamping block 521 being movably disposed on the sliding cylinder 540 along the radial direction of the sliding cylinder 540. The upper inner wall of the fixed cylinder 510 forms a downwardly tapering inclined surface 511, one end of each clamping block 521 is used to contact the outer periphery of the nozzle 21 of the welding torch 20, and the other end of each clamping block 521 is used to slide in contact with the inclined surface 511.

[0103] like Figure 6 As shown, the inclined surface 511 of the upper part of the fixed cylinder 510 gradually tapers from top to bottom, that is, the radial dimension of the upper inner wall of the fixed cylinder 510 gradually decreases from top to bottom. When each clamping block 21 slides downward along the inclined surface 511, each clamping block 21 will move radially inward at the same time.

[0104] For example, such as Figure 6 As shown, a receiving groove 511a may be provided at the inclined surface 511 of the fixed cylinder 510 to accommodate the ends of each clamping block 521, and the ends of each clamping block 521 can slide up and down along the receiving groove 511a. That is, the receiving groove 511a can limit and guide the up and down sliding of the clamping block 521.

[0105] In this embodiment, when the welding torch 20 is inserted into the fixed cylinder 510, the front end of the nozzle 21 of the welding torch 20 contacts the sliding cylinder 540 and drives the sliding cylinder 540 to move downward, so that each clamping block 521 can move downward together with the sliding cylinder 540; at the same time, each clamping block 521 can shrink inward along the radial direction of the sliding cylinder 540 under the guidance of the inclined surface 511 and move closer to each other, so as to clamp the nozzle 21.

[0106] See Figure 5 In one embodiment, the disassembly and assembly mechanism 500 further includes an elastic element 550 disposed between the bottom of the sliding cylinder 540 and the bottom wall of the fixed cylinder 510. The elastic element 550 is used to provide an upward elastic restoring force to the sliding cylinder 540.

[0107] The elastic element 550 can be a compression spring or a disc spring, etc. When the front end of the nozzle 21 contacts the sliding cylinder 540 and drives the sliding cylinder 540 to move downward, the elastic element 550 accumulates elastic restoring force. When the disassembly and assembly mechanism 500 disengages from the welding torch 20, the sliding cylinder 540 can return to its original position under the elastic restoring force of the elastic element 550, thereby facilitating the automatic release of the nozzle 21 by the multiple clamping blocks 521.

[0108] In addition, the elastic element 550 allows the sliding cylinder 540 to have a certain amount of floating within the fixed cylinder 510, which in turn allows the multiple clamping blocks 521 to also have a certain amount of floating. Therefore, when the fixed cylinder 510 rotates to remove the nozzle 21, the multiple clamping blocks 521 can clamp the nozzle 21 so that the nozzle 21 can be smoothly removed from the welding gun 20.

[0109] Furthermore, the disassembly and assembly mechanism 500 also includes a limiting cover 560. The limiting cover 560 is fixedly connected to the upper opening of the fixed cylinder 510. The limiting cover 560 may have a through hole for inserting the welding torch 20. In this embodiment, the limiting cover 560 is used to limit the upward sliding range of the sliding cylinder 540, thereby ensuring that the sliding cylinder 540 slides up and down inside the fixed cylinder 510, preventing the sliding cylinder 540 from detaching from the fixed cylinder 510, and improving the reliability of the disassembly and assembly mechanism 500.

[0110] In one embodiment, the fixed cylinder 510 includes a first cylinder 512 and a second cylinder 513 arranged coaxially. An inclined surface 511 is provided on the inner wall of the first cylinder 512. The bottom end of the first cylinder 512 is fixedly connected to the top end of the second cylinder 513, and the bottom end of the second cylinder 513 is rotatably connected to the turntable 320. In this embodiment, by setting the fixed cylinder 510 to include a first cylinder 512 and a second cylinder 513, the installation and arrangement of the internal components of the fixed cylinder 510 can be facilitated, and the manufacturing cost of the device can be reduced.

[0111] like Figure 6 As shown, in one embodiment, the disassembly and assembly mechanism 500 further includes a positioning post 570, which is disposed on the fixed cylinder 510 and extends radially into the sliding cylinder 540. The sliding cylinder 540 is provided with an axially extending groove 541 corresponding to the positioning post 570.

[0112] The number of positioning posts 570 can be multiple, and the multiple positioning posts 570 are arranged at intervals along the circumference of the fixed cylinder 510. In this embodiment, by setting the positioning posts 570, it can be ensured that the sliding cylinder 540 can only slide up and down within the fixed cylinder 510 along the axial direction, and that the sliding cylinder 540 and the fixed cylinder 510 cannot rotate relative to each other.

[0113] It is understood that the positioning post 570 may be omitted in other embodiments. At the same time, limiting grooves and limiting blocks are respectively provided on the surfaces of the fixed cylinder 510 and the sliding cylinder 540 that come into contact with each other. The limiting grooves and limiting blocks cooperate with each other to restrict the sliding cylinder 540 from rotating within the fixed cylinder 510.

[0114] In one embodiment, the end of the positioning post 570 extending into the sliding cylinder 540 is used to elastically contact the nozzle 21 of the welding torch 20. For example, the positioning post 570 can be a spring plunger. The spring plunger not only limits the sliding cylinder 540 to sliding up and down only axially within the fixed cylinder 510, but also maintains elastic contact with the outer periphery of the nozzle 21 of the welding torch 20, thereby providing a certain clamping force to the nozzle 21.

[0115] In this embodiment, when the sliding cylinder 540 is reset upward under the action of the elastic member 550, the multiple clamping blocks 521 move upward with the sliding cylinder 540. At this time, the multiple clamping blocks 521 cannot clamp the nozzle 21. However, because the spring plunger always has a certain clamping force on the nozzle 21, the nozzle 21 can remain fixed inside the fixed cylinder 510 so that the disassembly and assembly mechanism 500 can move together with the nozzle 21 to the nozzle cleaning mechanism 600.

[0116] It is understood that in other embodiments, a flexible structure such as a flexible pad may be provided at the end of the positioning post 570 that extends into the sliding cylinder 540, so that the end of the positioning post 570 can make elastic contact with the nozzle 21.

[0117] See Figure 2As shown in the embodiment of this application, the nozzle cleaning mechanism 600 is disposed above the turntable 320. Since the turntable 320 can rotate horizontally, it can drive the disassembly and assembly mechanism 500 on it to rotate horizontally relative to the frame 100. Thus, the disassembly and assembly mechanism 500 can move to a position corresponding vertically to the nozzle cleaning mechanism 600 as needed, and the nozzle cleaning mechanism 600 can clean the nozzles 21 on the disassembly and assembly mechanism 500.

[0118] like Figure 7 As shown, in one embodiment, the nozzle cleaning mechanism 600 includes a brush head 610, which is fixedly mounted on the frame 100. For example, the brush head 610 can be fixedly mounted on the top plate 110 of the frame 100 via a mounting plate 620. Specifically, the mounting plate 620 has a hole through which the brush head 610 passes. By passing the upper end of the brush head 610 through this hole and simultaneously using a limiting nut to thread a portion of the brush head 610 protruding from the top surface of the mounting plate 620, the brush head 610 can be fixedly mounted.

[0119] Furthermore, an abutment portion 630 may be provided on the bottom surface of the mounting plate 620. The abutment portion 630 is arranged around the outer periphery of the upper end of the brush head 610. The abutment portion 630 is used to abut against the tip of the nozzle 21. Preferably, the abutment portion 630 can be a bearing.

[0120] In this embodiment, after the disassembly mechanism 500 rotates and removes the nozzle 21, the lifting mechanism 400 can drive the turntable mechanism 300 to descend as a whole, thereby causing the fixed cylinder 510 to descend and disengage the nozzle 21 from the welding torch 20. Subsequently, the turntable 320 rotates, causing the disassembly mechanism 500 to move to a position corresponding to the nozzle cleaning mechanism 600. The lifting mechanism 400 then moves the turntable mechanism 300 to rise as a whole, allowing the brush head 610 to extend into the fixed cylinder 510 to clean the nozzle 21 inside the fixed cylinder 510.

[0121] Specifically, when the lifting mechanism 400 drives the turntable mechanism 300 to rise as a whole, the tip of the nozzle 21 inside the fixed cylinder 510 first abuts against the contact part 630. Therefore, as the turntable mechanism 300 continues to rise, the nozzle 21 can be clamped by multiple clamping blocks 520. At the same time, the brush head 610 can be inserted into the nozzle 21 clamped by the multiple clamping blocks 521. Then, the fixed cylinder 510 is driven to rotate by the first driving member 530, causing the nozzle 21 to rotate around the brush head 610, so that the brush head 610 can clean the inner surface of the nozzle 21.

[0122] like Figure 7As shown, preferably, a first slag discharge port 514 is provided at the bottom of the fixed cylinder 510. By providing the first slag discharge port 514, the welding slag falling from the cleaning nozzle 21 of the brush head 610 can be discharged directly downwards, thereby avoiding the accumulation of welding slag, ensuring the cleanliness of the inside of the fixed cylinder 510, and ensuring the normal operation of the disassembly and assembly mechanism 500.

[0123] like Figure 7 As shown, preferably, a through hole can be provided on the driven gear at the bottom end of the fixed cylinder 510 corresponding to the first slag discharge port 514 to facilitate the falling of welding slag.

[0124] See Figure 2 In one embodiment, there are two disassembly and assembly mechanisms 500, which are spaced apart on the turntable 320. The positions of the two disassembly and assembly mechanisms 500 correspond one-to-one with the positions of the fixed position and the nozzle cleaning mechanism 600, such that when one disassembly and assembly mechanism 500 is vertically aligned with the fixed position, the other disassembly and assembly mechanism 500 is vertically aligned with the nozzle cleaning mechanism 600.

[0125] In this embodiment, when one of the disassembly / assembly mechanisms 500 moves to a position corresponding vertically to the nozzle cleaning mechanism 600, the other disassembly / assembly mechanism 500 moves precisely to the position below the welding torch 20 held by the clamping mechanism 200 at the fixed position. Therefore, while the brush head 610 cleans the nozzle 21 removed from one disassembly / assembly mechanism 500, the other disassembly / assembly mechanism 500 can assemble its spare nozzle onto the welding torch 20 with the removed nozzle 21, thus replacing the nozzle 21. Consequently, the torch cleaning device 10 of this application can quickly clean and replace the nozzle 21, effectively improving efficiency and saving time.

[0126] See Figure 2 As shown in the embodiment of this application, the conductive tip cleaning mechanism 700 is disposed on the turntable 320. Since the turntable 320 can rotate horizontally, it can drive the conductive tip cleaning mechanism 700 thereon to rotate horizontally relative to the frame 100. Thus, the conductive tip cleaning mechanism 700 can move as needed to a position corresponding vertically to that of the welding torch 20 fixed at a fixed position, in order to clean the conductive tip 22 of the welding torch 20.

[0127] like Figure 8 As shown, in one embodiment, the conductive nozzle cleaning mechanism 700 includes a cleaning cylinder 710 and a second drive member 720, as well as a plurality of brushes 730.

[0128] The cleaning cylinder 710 is rotatably mounted on the turntable 320. A second driving member 720 is fixedly mounted on the turntable 320 and is motive-connected to the cleaning cylinder 710 to drive its rotation. The second driving member 720 can be a motor, which can drive the cleaning cylinder 710 to rotate via a gear set. For example, a driving gear can be fixedly mounted on the motor's output shaft, and a driven gear can be fixedly connected to the bottom end of the cleaning cylinder 710, with the driven gear meshing with the driving gear. Therefore, the motor can drive the driven gear to rotate via the driving gear, thereby driving the cleaning cylinder 710 to rotate.

[0129] like Figure 8 As shown, multiple brushes 730 are installed at intervals inside the cleaning cylinder 710. The multiple brushes 730 are used to clean the conductive nozzle 22 of the welding torch 20 that extends into the cleaning cylinder 710.

[0130] Specifically, after the disassembly mechanism 500 removes the nozzle 21, the lifting mechanism 400 drives the turntable mechanism 300 to descend as a whole, thereby lowering the fixing cylinder 510 and causing the nozzle 21 to disengage from the welding torch 20. At this time, the conductive tip 22 of the welding torch 20 held by the clamping mechanism 200 is exposed. Subsequently, the turntable 320 rotates, causing the conductive tip cleaning mechanism 700 to move to a position corresponding to the welding torch 20 on the clamping mechanism 200. The lifting mechanism 400 then moves the turntable mechanism 300 upward, allowing the conductive tip 22 to extend between the multiple brushes 730. Then, the second driving member 720 drives the cleaning cylinder 710 to rotate, causing the multiple brushes 730 to rotate around the conductive tip 22, thus cleaning the welding slag on the outer surface of the conductive tip 22.

[0131] In this embodiment, the rotation of the cleaning cylinder 710 drives multiple brushes 730 inside it to rotate around the conductive nozzle 22, which can effectively clean the conductive nozzle 22. Moreover, the conductive nozzle cleaning mechanism 700 has a simple structure, which helps to reduce the manufacturing cost of the device.

[0132] like Figure 8 As shown, in one embodiment, a second slag discharge port 711 is provided at the bottom of the cleaning cylinder 710. By providing the second slag discharge port 711, the welding slag that falls off when the multiple brushes 730 clean the conductive nozzle 22 can be directly discharged downwards, thereby avoiding the accumulation of welding slag, ensuring the cleanliness of the inside of the cleaning cylinder 710, and ensuring the normal operation of the conductive nozzle cleaning mechanism 700.

[0133] like Figure 8 As shown, preferably, a through hole can be provided on the driven gear at the bottom of the cleaning cylinder 710 corresponding to the second slag discharge port 711 to facilitate the falling off of welding slag.

[0134] See Figure 1As shown in the embodiments of this application, the wire cutting mechanism 800 is disposed on the frame 100. For example, the wire cutting mechanism 800 can be fixedly installed on the upper side wall of the frame 100.

[0135] like Figure 9 As shown, the wire cutting mechanism 800 may include a bracket 810, a first cutting blade 820 and a second cutting blade 830, and a third driving member 840. The first cutting blade 820 is fixedly mounted on the bracket 810, and one end of the first cutting blade 820 is provided with a first cutting opening 821.

[0136] The second shear blade 830 is hinged to the bracket 810 at its center. For example, a rotating hole may be provided in the center of the second shear blade 830, and a pin is fixed on the bracket 810, which passes through the rotating hole, so that the second shear blade 830 can be hinged to the bracket 810.

[0137] like Figure 9 As shown, the second shear blade 830 and the first shear blade 820 are stacked together, and one end of the second shear blade 830 is provided with a second shearing opening corresponding to the first shearing opening 821.

[0138] The third driving member 840 is drivenly connected to the other end of the second shear blade 830 and is used to drive that end of the second shear blade 830 to rotate around the hinge point, so that the second shearing opening and the first shearing opening 821 switch between mutually misaligned or mutually overlapping positions. The third driving member 840 may be a cylinder. The piston rod end of the cylinder is hinged to the end of the second shear blade 830.

[0139] In this embodiment, when the wire cutting mechanism 800 is working, the welding wire exposed by the welding gun 20 is inserted into the first cutting port 821 and the second cutting port. The cylinder piston rod extends and drives the second cutting blade 830 to rotate around the pin shaft, so that the second cutting port is misaligned with the first cutting port 821, thereby achieving the cutting of the welding wire.

[0140] like Figure 9 As shown, the wire cutting mechanism 800 may further include a collection box 850, which can be fixedly mounted on the bracket 810 and is correspondingly arranged below the first cutting opening 821 and the second cutting opening. The collection box 850 is used to collect the welding wire that falls off during cutting.

[0141] See Figure 2 As shown, in an embodiment of this application, the spraying mechanism 900 is mounted on the frame 100. Figure 10As shown, the spraying mechanism 900 may include a spraying body 910, a storage tank 920, and a collection tank 930. The spraying body 910 may be fixedly mounted on the upper side wall of the frame 100. For example, the spraying body 910 may be mounted on the same side of the frame 100 as the wire cutting mechanism 800, thereby facilitating the rapid movement of the welding torch 20 to the spraying mechanism 900 after the welding wire is cut. The storage tank 920 may be fixedly mounted on the base plate 120 of the frame 100.

[0142] like Figure 11 As shown, the spray body 910 is hollow inside and has a spray section 911. The spray section 911 has a spray nozzle 912, a first inlet 913, and a second inlet 914. The spray nozzle 912 is used to spray anti-spatter liquid into the welding torch 20 that extends into the spray body 910. The first inlet 913 is connected to the liquid storage tank 920 through a pipeline, and the second inlet 914 is connected to an external air source through a pipeline.

[0143] The external air source can be an air pump, which can be connected to the second inlet 914 through a pipeline to provide compressed air to the injection unit 911.

[0144] like Figure 11 As shown, the liquid collection tank 930 is connected to the bottom of the liquid spraying body 910 and communicates with the inner cavity of the liquid spraying body 910.

[0145] In this embodiment, when the spraying mechanism 900 is working, the end of the welding torch 20 is inserted into the spraying body 910, and the air pump is turned on, allowing compressed air to enter the spraying section 911 from the second inlet 914. The continuously supplied compressed air creates a negative pressure in the spraying section 911, thereby continuously drawing in anti-spatter liquid from the storage tank 920. The anti-spatter liquid mixes with the compressed air in the spraying section 911 and is sprayed from the spray port 912 onto the nozzle 21 and conductive tip 22 of the welding torch 20. Excess anti-spatter liquid can fall directly into the collection tank 930. The spraying mechanism 900 of this application has a simple structure, can spray anti-spatter liquid onto the welding torch 20, is easy to operate, and can also collect excess liquid to avoid waste.

[0146] See Figure 2 As shown, the cleaning process of the welding torch cleaning device 10 in this embodiment is roughly as follows:

[0147] First, the welding torch 20 is aligned and vertically inserted into the fixed cylinder 510 of the disassembly and assembly mechanism 500, either manually or using a robot. The front end of the nozzle 21 of the welding torch 20 contacts the sliding cylinder 540 and drives it downward. Each clamping block 521 moves downward with the sliding cylinder 540. Simultaneously, under the action of the inclined surface 511, each clamping block 521 also undergoes radial inward displacement along the sliding cylinder 540, thereby clamping the nozzle 21 of the welding torch 20. Then, the clamping mechanism 200 actuates, clamping the main body of the welding torch 20 and holding it in its current position. Subsequently, the first driving member 530 drives the fixed sleeve to rotate, thereby disassembling the nozzle 21 of the welding torch 20.

[0148] After nozzle 21 is disassembled, lifting mechanism 400 lowers turntable mechanism 300, disengaging nozzle 21 from welding torch 20. Turntable 320 then rotates 90° clockwise, aligning the cleaning cylinder 710 of conductive nozzle cleaning mechanism 700 with the conductive nozzle 22 at the end of welding torch 20. Lifting mechanism 400 raises turntable mechanism 300, placing cleaning cylinder 710 over the conductive nozzle 22 of welding torch 20. At this point, the conductive nozzle 22 of welding torch 20 extends between multiple brushes 730 inside cleaning cylinder 710. Subsequently, second drive unit 720 drives cleaning cylinder 710 to rotate, allowing multiple brushes 730 to clean the welding slag on conductive nozzle 22. During the cleaning process of conductive nozzle 22, the dislodged welding slag can be discharged from the second slag discharge port 711 at the bottom of cleaning cylinder 710.

[0149] After the conductive nozzle 22 is cleaned, the lifting mechanism 400 lowers to detach the cleaning cylinder 710 from the welding torch 20. Then, the turntable 320 rotates 90° clockwise again, aligning the disassembly / removal mechanism 500, which houses the disassembled nozzle 21, with the nozzle cleaning mechanism 600. The lifting mechanism 400 drives the turntable mechanism 300 to rise, and the contact portion 630 of the nozzle cleaning mechanism 600 contacts the tip of the nozzle 21, providing pressure and causing the nozzle 21 to move downwards and be clamped. After the turntable mechanism 300 reaches its position, the brush head 610 of the nozzle cleaning mechanism 600 extends into the interior of the nozzle 21. Subsequently, the first driving member 530 drives the fixed cylinder 510 to rotate, causing the nozzle 21 to rotate around the brush head 610, thereby cleaning the welding slag from the nozzle 21. During the cleaning process of the nozzle 21, the cleaned-off welding slag can be discharged from the first slag discharge port 514 at the bottom of the fixed cylinder 510. After the nozzle 21 has finished cleaning, the lifting mechanism 400 descends, and the nozzle 21 is separated from the brush head 610 under the clamping force of the spring plunger.

[0150] Since two disassembly and assembly mechanisms 500 are evenly distributed on the turntable 320, when cleaning the disassembled nozzle 21, the other disassembly and assembly mechanism 500 can simultaneously align the loaded spare nozzle with the welding torch 20, and under the drive of the first driving member 530, the spare nozzle is rotated and screwed into the welding torch 20, thereby realizing the replacement of the nozzle 21.

[0151] After nozzle 21 is replaced, clamping mechanism 200 is released, and the robot moves welding torch 20 to wire cutting mechanism 800 to cut the welding wire. When wire cutting mechanism 800 is working, the robot moves welding torch 20, causing the welding wire to be caught in the first cutting port 821 and the second cutting port. Third drive component 840 extends, causing second shear blade 830 to rotate around a pin, thus misaligning the second cutting port with the first cutting port 821 to complete the cutting of the welding wire. The cut welding wire can fall into collection box 850.

[0152] After the welding wire is cut, the robot moves the welding torch 20 to the spraying mechanism 900 to apply anti-spatter liquid. When the spraying mechanism 900 is working, the robot moves the welding torch 20, inserting the nozzle 21 into the inner cavity of the spraying body 910. The air pump is turned on, allowing compressed air to enter the spraying section 911 from the second inlet 914. The continuously supplied compressed air creates a negative pressure inside the spraying section 911, allowing it to continuously draw in anti-spatter liquid from the storage tank 920. The anti-spatter liquid mixes with the compressed air within the spraying section 911 and is sprayed from the spray nozzle 912 onto the nozzle 21 and contact tip 22 of the welding torch 20. Excess anti-spatter liquid falls directly into the collection tank 930.

[0153] Thus, the cleaning device 10 has completed the cleaning and replacement of the nozzle 21 and the cleaning of the conductive tip 22 of the welding torch 20.

[0154] It should be noted that when the nozzle 21 of the welding torch 20 needs to be cleaned or replaced again, the rotation direction of the turntable 320 can be opposite to the previous one to avoid the cables inside the device getting tangled.

[0155] The welding torch cleaning device of this application includes a frame, a turntable mechanism, a lifting mechanism, a disassembly and assembly mechanism, a nozzle cleaning mechanism, and a contact tip cleaning mechanism. The disassembly and assembly mechanism can disassemble or install the nozzle of the welding torch. The nozzle cleaning mechanism can clean the nozzle on the disassembly and assembly mechanism. The contact tip cleaning mechanism can clean the contact tip of the welding torch. The turntable mechanism can rotate and switch the positions of the disassembly and assembly mechanism and the contact tip cleaning mechanism to perform nozzle disassembly, assembly, and contact tip cleaning operations. The lifting mechanism can cooperate with the turntable mechanism to switch the vertical relative positions of the disassembly and assembly mechanism, the nozzle cleaning mechanism, the contact tip cleaning mechanism, and the nozzle and contact tip of the welding torch, thereby realizing the disassembly, assembly, and cleaning of the nozzle and the cleaning of the contact tip.

[0156] Therefore, the welding torch cleaning device of this application can disassemble, clean, assemble, and clean the nozzle of the welding torch as well as the conductive tip, thereby realizing automatic cleaning of the welding torch and nozzle replacement. Its structure is simple and easy to operate, which helps to improve the cleaning efficiency and save labor costs.

[0157] The welding torch cleaning device of this application integrates the disassembly and cleaning of the welding torch nozzle, the cleaning of the conductive tip, the cutting of the welding wire, and the spraying of anti-spatter liquid on the welding torch into one operation, which greatly simplifies the turnover process and improves the cleaning efficiency.

[0158] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.

[0159] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims.
