By controlling the mechanical arm and the supporting arm by the controller and under the linkage of the mechanical arm and the supporting arm, the welder can be driven to move and the position of the welder can be adjusted, so as to facilitate welding processing of automobile parts in different positions by the welder.

[0005] Preferably, the first camera and the second camera are installed at the same height, and the first camera and the second camera are electrically connected to the controller.

[0006] Preferably, the support column is installed vertically, and the annular extension edge and the roller are concentric circles.

[0007] Preferably, the rotary feeding mechanism includes a rotating worktable, the central axis of the bottom of the rotating worktable is rotatably installed with the middle of the top of the machine body, a material trough is opened on the side of the top of the rotating worktable, and a right-angled groove is opened on the inner side of the material trough, and a semicircular elastic sheet is fixedly connected to the edge of the surface of the rotating worktable and close to the opening of the material trough, and the inner side of the semicircular elastic sheet is fixedly connected to a clamping block, and the bottom of the semicircular elastic sheet is fixedly connected to a curved spring sheet, and the end of the curved spring sheet away from the semicircular elastic sheet is fixedly connected to an L-shaped hook, and the automobile parts blank that need to be welded is placed inside the material trough, and the automobile parts blank is embedded between the L-shaped hook and the clamping block, so that the automobile parts blank can be preliminarily positioned so that the automobile parts blank will not move or fall at will, and the rotating worktable is turned on to work, and the automobile parts blank can be fed to the bottom of the welder by rotating the rotating worktable clockwise.

[0008] The first camera is used to capture information about the automobile parts blanks being fed remotely from the top of the rotating worktable, and the collected information is transmitted to the controller in the form of electrical signals. The controller analyzes and processes the signals to determine the situation of the automobile parts blanks in the material trough at the top edge of the rotating worktable. When there are no automobile parts blanks in the material trough, the external device robot is used to reload the materials, and there will be no missing or missed materials. When there are automobile parts blanks in the material trough, the position of the automobile parts blanks can be accurately located. As the rotating worktable continues to rotate, when the automobile parts blanks rotate to the bottom of the welder, the rotating worktable is paused and the automobile parts blanks stop moving, so that the welder can perform welding work in sequence.

[0009] Preferably, there are five material troughs, and the five material troughs are evenly distributed on the sides of the top of the rotating workbench, and the semicircular elastic sheet and the material trough are installed at the same height.

[0010] When the welder has completed welding the auto parts blank, the mechanical arm and the supporting arm can be used to lift the welder again, and the workbench can be rotated clockwise to move the welded auto parts out. The squeezing force of the semicircular elastic sheet due to the roller disappears, and under the elastic force of the semicircular elastic sheet, the semicircular elastic sheet drives the curved spring sheet and the L-shaped hook to move outward for reset, and the L-shaped hook can be used to apply pulling force to the auto parts, so that the auto parts are displaced outward for subsequent removal of the auto parts.

[0011] The surface of the semicircular elastic sheet is fitted with the surface of the roller, so that the semicircular elastic sheet is subjected to the pushing force of the roller. The roller rolls and installs the semicircular elastic sheet, so that the semicircular elastic sheet is elastically deformed under pressure, so that the clamping block can fit with the automobile parts blank in the material trough, so that the automobile parts blank can be clamped and fixed.

When the auto parts have been welded, the rotating workbench can continue to rotate clockwise. When the auto parts have not been welded, the rotating workbench can be rotated counterclockwise to return to the welding position, and the welder can be used again to re-weld the auto parts to avoid welding errors and omissions.

[0013] Preferably, a unloading mechanism is installed at the side of the body surface, and the unloading mechanism includes a support frame, which is fixed to the side of the body surface by screws, an active circular roller is rotatably installed on one end of the top of the support frame, a driven circular roller is rotatably installed on the top of the support frame and at one end away from the active circular roller, a conveyor belt is installed between the active circular roller and the driven circular roller, a servo motor is fixedly installed on the top of the support frame surface and at one end close to the active circular roller, and a material picking assembly is installed on the top of the support frame and at one end close to the driven circular roller.

[0014] Preferably, one end of the active circular roller is fixedly mounted to the output end of the servo motor via a coupling, and the driven circular roller and the active circular roller are mounted at the same height.

[0015] Preferably, the material-picking assembly includes a strip guide rail, which is fixedly mounted on the top of the support frame surface and close to one end of the driven circular roller, and a right-angle frame is slidably mounted on the surface of the strip guide rail through a slider, and a return spring is fixedly connected between the slider surface at the bottom of the right-angle frame and the inner wall of the strip guide rail, a hydraulic cylinder is fixedly mounted on the side of the top of the right-angle frame, and the telescopic end of the hydraulic cylinder is fixedly connected to an air pump, and a right-angle air pipe is installed at the air port at the bottom of the air pump surface, and a connecting square rod is fixedly connected to the slider surface at the bottom of the right-angle frame and the side away from the return spring, and the bottom end of the connecting square rod and the end of the slider away from the bottom of the right-angle frame A force-bearing wheel is installed by rolling a pin shaft. As the rotating workbench rotates the welded auto parts clockwise to just below the air pump, the rotating workbench can be paused again. The air pump can be pushed downward by extending the telescopic end of the hydraulic cylinder, so that the right-angle air pipe moves downward together. The air port at the bottom of the right-angle air pipe is fitted with the top of the auto parts, and the air in the right-angle air pipe is sucked out by the suction of the air pump. The auto parts can be sucked up by forming a negative pressure in the right-angle air pipe, and the air pump and auto parts can be lifted by contracting the telescopic end of the hydraulic cylinder, thereby unloading the auto parts for subsequent batch processing.

[0016] Preferably, there are two strip guide rails, and the two strip guide rails are symmetrically installed along the central axis in the middle of the conveyor belt, the hydraulic cylinder is installed vertically, the air port of the right-angle air pipe is facing downward, and the return spring is installed in the middle of the inside of the strip guide rail, and the rotating workbench is used to drive the semicircular elastic sheet to rotate, and the surface of the semicircular elastic sheet contacts the surface of the force wheel, so that the force wheel is subjected to a driving force, and under the connection of the connecting square rod, the slider at the bottom end of the right-angle frame is subjected to a driving force, and combined with the elastic force of the semicircular elastic sheet is greater than the elastic force of the return spring, so that the right-angle frame drives the lifted auto parts to move to the side away from the rotating workbench, and the return spring is compressed. When the auto parts move out of the top of the L-shaped hook, the telescopic end of the hydraulic cylinder is extended to lower the auto parts onto the conveyor belt, and the air pump is turned off, so that the auto parts fall onto the conveyor belt, and then they can be unloaded.

[0017] The present invention provides an error-proof and leak-proof welding device for automobile parts. It has the following beneficial effects: 1. This error-proof automobile parts welding device controls the mechanical arm and the supporting arm through the controller. Under the linkage of the mechanical arm and the supporting arm, the welder can be driven to move and the position of the welder can be adjusted, thereby facilitating the welding of automobile parts in different positions through the welder.

[0018] Second, the error-proof automobile parts welding device places the automobile parts blanks that need to be welded in the material trough between the mechanical arm and the support frame, and the automobile parts blanks are embedded between the L-shaped hook and the clamping block, so that the automobile parts blanks can be preliminarily positioned to prevent them from moving or falling at will. The rotating workbench is then turned on to work, and the automobile parts blanks can be loaded to the bottom of the welder by rotating the rotating workbench clockwise.

[0019] 3. The error-proof automobile parts welding device uses a first camera to capture information about automobile parts blanks and uses a controller to analyze and process the signals to determine the status of automobile parts blanks in a material trough at the top edge of a rotating worktable. When there are no automobile parts blanks in the material trough, the external device robot is used to reload the materials, and there will be no missing or vacant materials.

[0020] 4. The error-proof automobile parts welding device utilizes the surface of the semicircular elastic sheet to fit with the surface of the roller, so that the semicircular elastic sheet is pushed by the roller, and the roller rolls the semicircular elastic sheet to make it elastically deformed under pressure, so that the clamping block can fit with the automobile parts blank in the material trough, so that the automobile parts blank can be clamped and fixed. After being squeezed, the clamping block is deformed to fill the gap between the inner side of the semicircular elastic sheet and the surface of the automobile parts blank, so that the automobile parts blank can be clamped stably without loosening.

[0021] 5. The error-proof automobile parts welding device uses the linkage of the mechanical arm and the supporting arm to lift the welder and move the welded automobile parts out by rotating the workbench clockwise. The squeezing force of the semicircular elastic piece by the roller disappears, and under the elastic force of the semicircular elastic piece, the semicircular elastic piece drives the curved spring piece and the L-shaped hook to move outward for reset. The L-shaped hook can then apply a pulling force to the automobile parts, causing the automobile parts to move outward so that the automobile parts can be removed later.

[0022] 6. This error-proof auto parts welding device, when the workbench is rotated to move the auto parts out, the second camera captures and collects information about the removed auto parts, and transmits the information collected by the second camera to the controller in the form of an electrical signal. The controller can then process and analyze the signal. If it detects that the auto parts are not welded, the workbench is rotated counterclockwise to return to the welding position, and the welder is used again to re-weld the auto parts, thereby avoiding welding errors and omissions.

[0023] 7. The error-proof automobile parts welding device uses the extension of the telescopic end of the hydraulic cylinder to push the air pump downward, causing the right-angle air pipe to move downward together. The air port at the bottom of the right-angle air pipe is fitted with the top of the automobile part, and the air pump suctions the air in the right-angle air pipe. The negative pressure formed in the right-angle air pipe can be used to suck up the automobile parts, and the air pump and automobile parts can be lifted by contracting the telescopic end of the hydraulic cylinder, thereby unloading the automobile parts for subsequent batch processing.

[0024] 8. The error-proof automobile parts welding device, through the contact between the surface of the semicircular elastic sheet and the surface of the force wheel, causes the force wheel to be pushed, and the slider at the bottom end of the right-angle frame to be pushed. Combined with the elastic force of the semicircular elastic sheet being greater than the elastic force of the return spring, the right-angle frame drives the lifted automobile parts to move to the side away from the rotating workbench, and the return spring is compressed. When the automobile parts move out from above the L-shaped hook, the telescopic end of the hydraulic cylinder is extended to lower the automobile parts onto the conveyor belt, and the air pump is turned off, so that the automobile parts fall onto the conveyor belt and can be unloaded.

A second camera 46 is installed, and a support column 47 is fixedly installed on the side of the top of the controller 41. A roller 48 is rotatably installed on the top of the support column 47, and a circular extension edge 49 is fixedly connected to the edge of the top of the roller 48. The controller 41 controls the mechanical arm 42 and the supporting arm 43, and under the linkage of the mechanical arm 42 and the supporting arm 43, the welder 44 can be driven to move and the position of the welder 44 can be adjusted, so as to facilitate the welding of automobile parts in different positions through the welder 44.

[0029] The first camera 45 and the second camera 46 are installed at the same height, and the first camera 45 and the second camera 46 are electrically connected to the controller 41 .

[0030] The support column 47 is installed vertically, and the annular extension edge 49 and the roller 48 are concentric circles.

[0031] The second embodiment, based on the first embodiment, see Figures 1 to 6 As shown: The rotary feeding mechanism 3 includes a rotating workbench 31, the central axis of the bottom of the rotating workbench 31 is rotatably installed with the middle of the top of the machine body 1, a material trough 32 is opened on the side of the top of the rotating workbench 31, and a right-angled groove 33 is opened on the inner side of the material trough 32. A semicircular elastic piece 34 is fixedly connected to the edge of the surface of the rotating workbench 31 and near the opening of the material trough 32. A clamping block 35 is fixedly connected to the inner side of the semicircular elastic piece 34. A curved elastic piece 36 is fixedly connected to the bottom of the semicircular elastic piece 34. The curved elastic piece 36 is away from the semicircular elastic piece 34. One end of the circular elastic sheet 34 is fixedly connected to an L-shaped hook 37. The staff controls the manipulator of the external equipment and places the automobile parts blank that needs to be welded into the material trough 32 through the manipulator. The automobile parts blank is embedded between the L-shaped hook 37 and the clamping block 35, so that the automobile parts blank can be preliminarily positioned so that the automobile parts blank will not move or fall at will. The rotating workbench 31 is then turned on to work. By rotating the rotating workbench 31 clockwise, the automobile parts blank can be loaded to the bottom of the welder 44.

[0032] The first camera 45 is used to capture information about the automobile parts blanks being fed remotely from the top of the rotating worktable 31, and the collected information is transmitted to the controller 41 in the form of electrical signals. The controller 41 analyzes and processes the signals to determine the situation of the automobile parts blanks in the material slot 32 at the top edge of the rotating worktable 31. When there are no automobile parts blanks in the material slot 32, the external device robot is used to reload the materials, and there will be no missing or vacant materials. When there are automobile parts blanks in the material slot 32, the position of the automobile parts blanks can be accurately located. As the rotating worktable 31 continues to rotate, when the automobile parts blanks rotate to the bottom of the welder 44, the rotating worktable 31 is paused, and the automobile parts blanks stop moving, so that the welder 44 can perform welding work in sequence.

[0033] There are five material troughs 32, and the five material troughs 32 are evenly distributed on the sides of the top of the rotating workbench 31. The semicircular elastic sheet 34 is installed at the same height as the material trough 32. When the rotating workbench 31 rotates, it will drive the semicircular elastic sheet 34 to rotate together. The surface of the semicircular elastic sheet 34 is fitted with the surface of the roller 48, so that the semicircular elastic sheet 34 is pushed by the roller 48. The roller 48 rolls the semicircular elastic sheet 34, so that the semicircular elastic sheet 34 is elastically deformed under pressure, so that the clamping block 35 can fit with the automotive parts blank in the material trough 32, so that the automotive parts blank can be clamped and fixed. The clamping block 35 is deformed after being squeezed, filling the gap between the inner side of the semicircular elastic sheet 34 and the surface of the automotive parts blank, and stably clamping the automotive parts blank.

[0034] The L-shaped hook 37 is slidably installed between the right-angled groove 33. The material of the clamping block 35 is rubber. The curved spring piece 36 is installed directly below the clamping block 35. When the welder 44 completes the welding of the automobile parts blank, the mechanical arm 42 and the supporting arm 43 can be used again to lift the welder 44, and the workbench 31 can be rotated clockwise to move the welded automobile parts out. The semicircular elastic piece 34 is squeezed by the roller 48 and the squeezing force disappears. Under the elastic force of the semicircular elastic piece 34, the semicircular elastic piece 34 drives the curved spring piece 36 and the L-shaped hook 37 to move outward for reset, and the L-shaped hook 37 can be used to apply pulling force to the automobile parts, and the automobile parts are displaced outward.

[0035] After the rotating workbench 31 moves the auto parts out, the second camera 46 captures the removed auto parts and collects information, and uses the information collected by the second camera 46 to transmit to the controller 41 in the form of an electrical signal, and the controller 41 can then process and analyze the signal. When the auto parts have been welded, the rotating workbench 31 can continue to rotate clockwise. When the auto parts have not been welded, the rotating workbench 31 can be rotated counterclockwise to return to the welding position, and the welder 44 can be used again to perform re-welding processing to avoid welding errors and omissions of auto parts.

[0036] The third embodiment, based on the first and second embodiments, see Figures 1 to 8 As shown: A discharge mechanism 5 is installed on the side of the surface of the body 1. The discharge mechanism 5 includes a support frame 51, which is fixed to the side of the surface of the body 1 by screws. A driving roller 52 is rollingly installed on one end of the top of the support frame 51, and a driven roller 53 is rollingly installed on the top of the support frame 51 and away from the driving roller 52. A conveyor belt 54 is installed between the driving roller 52 and the driven roller 53. A servo motor 55 is fixedly installed on the top of the surface of the support frame 51 and close to the driving roller 52. A material-taking component 56 is installed on the top of the support frame 51 and close to the driven roller 53. As the workbench 31 rotates, the welded steam When the auto parts rotate clockwise to just below the air pump 565, the rotating workbench 31 can be paused again, and the hydraulic cylinder 564 can be started to work. The extension of the telescopic end of the hydraulic cylinder 564 can be used to push the air pump 565 downward, causing the right-angle air pipe 566 to move downward together. The air port at the bottom end of the right-angle air pipe 566 is used to fit with the top of the auto parts, and the air in the right-angle air pipe 566 is sucked out by the suction of the air pump 565. The negative pressure is formed in the right-angle air pipe 566, which can suck up the auto parts. The telescopic end of the hydraulic cylinder 564 is contracted to lift the air pump 565 and the auto parts, and the auto parts are unloaded.

[0037] One end of the driving roller 52 is fixedly mounted to the output end of the servo motor 55 via a coupling, and the driven roller 53 is mounted at the same height as the driving roller 52 .

[0038] The material picking assembly 56 includes a strip guide rail 561, which is fixedly mounted on the top of the support frame 51 surface and close to one end of the driven circular roller 53. A right-angle frame 562 is slidably mounted on the surface of the strip guide rail 561 through a slider. A return spring 563 is fixedly connected between the slider surface at the bottom of the right-angle frame 562 and the inner wall of the strip guide rail 561. A hydraulic cylinder 564 is fixedly mounted on the side of the top of the right-angle frame 562. The telescopic end of the hydraulic cylinder 564 is fixedly connected to an air pump 565. A right-angle air pipe 566 is installed at the air port at the bottom of the surface of the air pump 565. A connecting square rod 567 is fixedly connected to the slider surface at the bottom of the right-angle frame 562 and on the side away from the return spring 563. A force wheel 568 is rollingly mounted on the bottom end of the connecting square rod 567 and one end of the slider away from the bottom of the right-angle frame 562 through a pin shaft.

[0039] There are two strip guide rails 561, and the two strip guide rails 561 are symmetrically installed along the central axis in the middle of the conveyor belt 54. The hydraulic cylinder 564 is installed vertically, the air port of the right-angle air pipe 566 is facing downward, and the return spring 563 is installed in the middle of the strip guide rail 561. When the bottom end of the right-angle air pipe 566 sucks up the auto parts and completes the material collection, the rotating workbench 31 is used again to drive the semicircular elastic sheet 34 to rotate. The surface of the semicircular elastic sheet 34 contacts the surface of the force wheel 568, so that the force wheel 568 is pushed, and under the connection of the connecting square rod 567, the slider at the bottom end of the right-angle frame 562 is pushed, and combined with the elastic force of the semicircular elastic sheet 34 being greater than the elastic force of the return spring 563, the right-angle frame 562 drives the lifted auto parts to move to the side away from the rotating workbench 31, and the return spring 563 is compressed. When the auto parts move out from above the L-shaped hook 37, the telescopic end of the hydraulic cylinder 564 is extended to lower the auto parts onto the conveyor belt 54, and the air pump 565 is turned off so that the auto parts fall onto the conveyor belt 54 for unloading. The servo motor 55 is turned on to work, and the output end of the servo motor 55 is used to drive the active circular roller 52 to roll. Under the rolling support of the driven circular roller 53, the conveyor belt 54 is operated to move the auto parts out. As the semicircular elastic sheet 34 separates from the force wheel 568, the pushing force of the semicircular elastic sheet 34 on the force wheel 568 disappears, and under the elastic force of the reset spring 563, the right-angle frame 562 drives the air pump 565 to move to the side close to the rotating workbench 31 for reset, so as to facilitate the subsequent unloading of auto parts.

[0040] During use, the staff first controls the manipulator of the external device to place the automobile part blank that needs to be welded into the material slot 32 between the mechanical arm 42 and the support frame 51 through the manipulator, and the automobile part blank is embedded between the L-shaped hook 37 and the clamping block 35, so that the automobile part blank can be preliminarily positioned to prevent it from moving or falling at will. Then, the rotating table 31 is turned on to work, and the automobile part blank can be loaded onto the bottom of the welder 44 by rotating the rotating table 31 clockwise. At this time, the first camera 45 captures and collects information about the automobile parts blanks being fed remotely from the top of the rotating worktable 31, and transmits the collected information to the controller 41 in the form of electrical signals. The controller 41 analyzes and processes the signals to determine the situation of the automobile parts blanks in the material slot 32 at the top edge of the rotating worktable 31. When there are no automobile parts blanks in the material slot 32, the external device manipulator reloads the materials, and there will be no vacant or missed materials. When there are automobile parts blanks in the material slot 32, the position of the automobile parts blanks can be accurately located. As the rotating worktable 31 continues to rotate, when the automobile parts blanks rotate to just below the welder 44, the rotating worktable 31 is paused and the automobile parts blanks stop moving. At the same time, the surface of the semicircular elastic piece 34 is fitted with the surface of the roller 48, so that the semicircular elastic piece 34 is pushed by the roller 48, and the roller 48 rolls and installs the semicircular elastic piece 34, so that the semicircular elastic piece 34 is elastically deformed under pressure, so that the clamping block 35 can fit with the automobile part blank in the material trough 32, so that the automobile part blank can be clamped and fixed. The clamping block 35 is deformed after being squeezed, filling the gap between the inner side of the semicircular elastic piece 34 and the surface of the automobile part blank, and stably clamping the automobile part blank; Furthermore, by controlling the mechanical arm 42 and the supporting arm 43 through the controller 41 and by the linkage between the mechanical arm 42 and the supporting arm 43, the welder 44 can be moved and the position of the welder 44 can be adjusted, thereby facilitating the welding of automobile parts at different positions through the welder 44. When the welder 44 has completed welding the automobile part blank, the mechanical arm 42 and the supporting arm 43 can be used to lift the welder 44 again, and the rotating table 31 can be rotated clockwise to remove the welded automobile part. The squeezing force of the semicircular elastic piece 34 by the roller 48 disappears, and under the elastic force of the semicircular elastic piece 34, the semicircular elastic piece 34 drives the curved spring piece 36 and the L-shaped hook 37 to move outward to reset. The L-shaped hook 37 can then apply a pulling force to the automobile part, causing the automobile part to move outward. After the rotating workbench 31 moves the auto parts out, the second camera 46 captures and collects information about the removed auto parts. The information collected by the second camera 46 is transmitted to the controller 41 in the form of an electrical signal, which is then processed and analyzed by the controller 41. When the auto parts have been welded, the rotating workbench 31 can be rotated clockwise. When the auto parts have not been welded, the rotating workbench 31 can be rotated counterclockwise to return to the welding position, and the welder 44 can be used to re-weld them, thereby avoiding welding errors and omissions of auto parts. Moreover, as the rotating workbench 31 rotates the welded automobile parts clockwise to just below the air pump 565, the rotating workbench 31 can be paused again, and the hydraulic cylinder 564 can be started to work. The extension of the telescopic end of the hydraulic cylinder 564 can push the air pump 565 downward, so that the right-angle air pipe 566 moves downward together, and the air port at the bottom end of the right-angle air pipe 566 is fitted with the top of the automobile parts, and the air in the right-angle air pipe 566 is sucked out by the suction of the air pump 565. The negative pressure is formed in the right-angle air pipe 566, and the automobile parts can be sucked up. The telescopic end of the hydraulic cylinder 564 is contracted to lift the air pump 565 and the automobile parts, and the automobile parts are unloaded. When the bottom end of the right-angle air pipe 566 sucks up the automobile parts and takes out the materials, the rotating workbench 31 is used again to drive the semicircular elastic piece 34 to rotate. The surface of the semicircular elastic piece 34 contacts the surface of the force-bearing wheel 568, so that the force-bearing wheel 568 is pushed, and under the connection of the connecting square rod 567, the slider at the bottom end of the right-angle frame 562 is pushed, and combined with the elastic force of the semicircular elastic piece 34 being greater than the elastic force of the return spring 563, the right-angle frame 562 drives the lifted automobile parts to move to the side away from the rotating workbench 31, and the return spring 563 is compressed. When the automobile parts move out of the top of the L-shaped draw hook 37, the telescopic end of the hydraulic cylinder 564 is extended, The auto parts are lowered onto the conveyor belt 54, and the air pump 565 is turned off so that the auto parts fall onto the conveyor belt 54 and can be unloaded. The servo motor 55 is turned on to work, and the output end of the servo motor 55 is used to drive the active circular roller 52 to roll, and under the rolling support of the driven circular roller 53, the conveyor belt 54 is operated to move the auto parts out. As the semicircular elastic piece 34 separates from the force wheel 568, the pushing force of the semicircular elastic piece 34 on the force wheel 568 disappears, and under the elastic force of the reset spring 563, the right-angle frame 562 drives the air pump 565 to move to the side close to the rotating workbench 31 for reset, so as to facilitate the subsequent unloading of auto parts.
