Description
Technical Field
[0001] This invention relates to the field of welding technology, specifically to a welding device for automotive parts that prevents errors and omissions. Background Technology
[0002] With the continuous development of technology and the rapid progress of society, automobiles are increasingly used in daily life. Automotive parts processing comprises the various units that make up the entire automotive parts processing system and the products that serve it. As the foundation of the automotive industry, automotive parts are a necessary factor supporting its continued healthy development. In the automotive industry, welding is a crucial link in the manufacturing of automotive parts and the car body, playing a special role in connecting the two processes. During the automotive manufacturing process, many parts require welding; therefore, welding equipment is essential.
[0003] Currently, the welding of existing automotive parts is affected by batch processing and assembly line operations, making it inconvenient to weld in sequence. This can easily lead to errors and omissions in the welding of automotive parts, affecting the overall welding quality of the batch. Summary of the Invention
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] A welding apparatus for preventing errors and omissions in automotive parts, comprising:
[0006] The machine body, and the base fixedly installed at the bottom of the machine body, wherein a rotary feeding mechanism is installed at the middle of the top of the machine body;
[0007] A processing mechanism for welding automotive parts, the processing mechanism being mounted on the side of the body surface;
[0008] The processing mechanism includes a controller, a mechanical arm, and a supporting arm. The controller is fixedly installed on the side of the machine body. The mechanical arm is installed at the center of the top of the controller. The supporting arm is installed at the top of the mechanical arm. A welder is installed on the surface of the supporting arm away from the mechanical arm. A first camera is fixedly installed on the supporting arm away from the mechanical arm and close to the welder. A second camera is fixedly installed on the side of the surface of the welder. A support column is fixedly installed on the side of the top of the controller. A roller is rotatably installed on the top of the support column. An annular extension edge is fixedly connected to the edge of the top of the roller. By controlling the mechanical arm and the supporting arm through the controller, and with the linkage of the mechanical arm and the supporting arm, the welder can be moved and its position adjusted, thereby facilitating the welding processing of automotive parts in different locations.
[0009] 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.
[0010] Preferably, the support column is installed vertically, and the annular extension edge is concentric with the roller.
[0011] Preferably, the rotary feeding mechanism includes a rotating worktable, which is rotatably mounted at the midpoint between the central axis of its bottom and the top of the machine body. A material trough is provided on the side of the top of the rotating worktable, and a right-angled groove is provided on the inner side of the material trough. A semi-circular elastic sheet is fixedly connected to the edge of the rotating worktable surface near the opening of the material trough. A clamping block is fixedly connected to the inner side of the semi-circular elastic sheet. A curved spring is fixedly connected to the bottom of the semi-circular elastic sheet, and an L-shaped hook is fixedly connected to the end of the curved spring away from the semi-circular elastic sheet. When the automotive part blank to be welded is placed inside the material trough and embedded between the L-shaped hook and the clamping block, the automotive part blank can be initially positioned, preventing it from moving or falling off. The rotating worktable is then turned on for operation. By rotating the worktable clockwise, the automotive part blank can be fed to the bottom of the welder.
[0012] The first camera captures images of the automotive part blanks fed remotely from the top of the rotating worktable, and transmits the collected information to the controller in the form of electrical signals. The controller analyzes and processes the signals to determine the status of the automotive part blanks in the material trough at the top edge of the rotating worktable. When there are no automotive part blanks in the material trough, an external robotic arm refills the trough, ensuring no gaps or omissions. When there are automotive part blanks in the material trough, the position of the automotive part blanks can be accurately located. As the rotating worktable continues to rotate, when the automotive part blanks rotate to a position directly below the welder, the rotating worktable stops working, and the automotive part blanks stop moving, allowing the welder to perform welding operations in sequence.
[0013] Preferably, there are five material troughs, and the five material troughs are evenly distributed on the side of the top of the rotating worktable, and the semi-circular elastic sheet is installed at the same height as the material troughs.
[0014] After the welding machine finishes welding the automotive part blank, the welding machine can be lifted again by the linkage of the mechanical arm and the supporting arm. The welded automotive part is then removed by rotating the worktable clockwise. The pressure of the roller on the semi-circular elastic plate disappears, and under the elastic force of the semi-circular elastic plate, the semi-circular elastic plate drives the curved spring and L-shaped pull hook to move outward to reset. The L-shaped pull hook can then apply a pulling force to the automotive part, thereby causing the automotive part to move outward so that it can be removed later.
[0015] By utilizing the contact between the surface of the semi-circular elastic sheet and the surface of the roller, the semi-circular elastic sheet is pushed by the roller. The roller rolls the semi-circular elastic sheet, causing it to deform elastically under pressure. This allows the clamping block to contact the automotive part blank in the material tank, thus clamping and fixing the automotive part blank. When the clamping block is compressed, it deforms and fills the gap between the inner side of the semi-circular elastic sheet and the surface of the automotive part blank, thus providing stable clamping of the automotive part blank without loosening.
[0016] Preferably, the L-shaped hook is slidably installed between the right-angled groove and the clamping block is made of rubber. The curved spring is installed directly below the clamping block. When the rotating worktable moves the car parts out, the second camera captures information of the moved car parts and transmits the information captured by the second camera to the controller in the form of an electrical signal. The controller can then process and analyze the signal. When the car parts have been welded, the rotating worktable can continue to rotate clockwise. When the car parts have not been welded, the rotating worktable can be rotated counterclockwise to return to the welding position and re-welded using the welding machine to avoid welding errors and omissions of car parts.
[0017] Preferably, a material unloading mechanism is installed on the side of the machine body surface. The material unloading mechanism includes a support frame, which is fixedly installed to the side of the machine body surface by screws. A drive roller is rotatably installed at one end of the top of the support frame, and a driven roller is rotatably installed at the top of the support frame away from the drive roller. A conveyor belt is installed between the drive roller and the driven roller. A servo motor is fixedly installed at the top of the support frame surface near the drive roller, and a material picking component is installed at the top of the support frame near the driven roller.
[0018] Preferably, one end of the driving roller is fixedly installed to the output end of the servo motor via a coupling, and the driven roller and the driving roller are installed at the same height.
[0019] Preferably, the material handling assembly includes a strip guide rail, which is fixedly installed on the top of the support frame surface and near the driven roller. A right-angle frame is slidably mounted on the surface of the strip guide rail via a slider. 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 installed on the side of the top of the right-angle frame. An air pump is fixedly connected to the telescopic end of the hydraulic cylinder. A right-angle air pipe is installed at the air port at the bottom of the air pump surface. A connecting square rod is fixedly connected to the slider surface at the bottom of the right-angle frame and away from the return spring. The bottom end of the connecting square rod and away from the slider at the bottom of the right-angle frame... A force-bearing wheel is mounted on a pin. As the rotating worktable rotates clockwise, the already welded automotive parts are positioned directly below the air pump. The worktable can then be paused again. By extending the telescopic end of the hydraulic cylinder, the air pump is pushed downwards, causing the right-angle air tube to move downwards as well. The air inlet at the bottom of the right-angle air tube is brought into contact with the top of the automotive parts. The air pump draws air out of the right-angle air tube, creating a negative pressure that lifts the automotive parts. The retraction of the telescopic end of the hydraulic cylinder then lifts the air pump and the automotive parts, unloading them for subsequent batch processing.
[0020] Preferably, there are two strip guide rails, and the two strip guide rails are symmetrically installed along the central axis of the middle of the conveyor belt. The hydraulic cylinder is installed vertically, the air port of the right-angle air pipe faces downward, and the return spring is installed in the middle of the inside of the strip guide rail. The rotating worktable drives the semi-circular elastic plate to rotate. The surface of the semi-circular elastic plate contacts the surface of the force wheel, so that the force wheel is pushed. Under the connection of the connecting square rod, the slider at the bottom of the right-angle frame is pushed. Combined with the fact that the elastic force of the semi-circular elastic plate is greater than the elastic force of the return spring, the right-angle frame moves the lifted car parts together to the side away from the rotating worktable, and the return spring is compressed. When the car parts move out of the L-shaped hook, the extension of the telescopic end of the hydraulic cylinder lowers the car parts onto the conveyor belt, and the air pump is turned off, so that the car parts fall onto the conveyor belt and can be unloaded.
[0021] This invention provides a welding device for automotive parts that prevents errors and omissions. It has the following beneficial effects:
[0022] I. This error-proof automotive parts welding device controls the mechanical boom and the supporting arm through a controller. With the linkage between the mechanical boom and the supporting arm, the welding machine can be moved and its position adjusted, thus facilitating the welding of automotive parts in different locations.
[0023] 2. This error-proof automotive parts welding device places the automotive parts blanks to be welded inside the material trough between the mechanical arm and the support frame. The automotive parts blanks are embedded between the L-shaped hooks and the clamping blocks, which can initially position the automotive parts blanks, preventing them from moving or falling off at will. The rotating worktable is then turned on to start working. By rotating the worktable clockwise, the automotive parts blanks can be fed to the bottom of the welding machine.
[0024] Third, the automotive parts welding device that prevents omissions and errors collects information by taking pictures of the automotive parts blanks with the first camera. The controller analyzes and processes the signals to determine the status of the automotive parts blanks in the material trough at the top edge of the rotating worktable. When there are no automotive parts blanks in the material trough, the external robotic arm will refill the material, preventing any omissions or gaps in the material loading.
[0025] IV. This error-proof automotive parts welding device utilizes the contact between the surface of a semi-circular elastic sheet and the surface of a roller, allowing the semi-circular elastic sheet to be pushed by the roller. The roller rolls the semi-circular elastic sheet, causing it to deform elastically under pressure. This allows the clamping block to contact the automotive parts blank in the material trough, thus clamping and fixing the automotive parts blank. When the clamping block is compressed, it deforms and fills the gap between the inner side of the semi-circular elastic sheet and the surface of the automotive parts blank, thus providing stable clamping of the automotive parts blank without loosening.
[0026] 5. This error-proof automotive parts welding device uses the linkage of the mechanical arm and the supporting arm to lift the welding machine. By rotating the worktable clockwise, the welded automotive parts are removed. The pressure of the roller on the semi-circular elastic plate disappears, and under the elastic force of the semi-circular elastic plate, the semi-circular elastic plate drives the curved elastic plate and the L-shaped pull hook to move outward for resetting. The L-shaped pull hook can then apply a pulling force to the automotive parts, thereby causing the automotive parts to move outward so that they can be removed later.
[0027] VI. In this error-proof automotive parts welding device, after the rotating worktable moves the automotive parts out, the second camera captures and collects information from the moved-out automotive parts. The information collected by the second camera is transmitted to the controller in the form of an electrical signal. The controller can then process and analyze the signal. If it is detected that the automotive parts have not been welded, the rotating worktable is rotated counterclockwise to return to the welding position, and the welding machine is used to re-weld the parts, thus avoiding welding errors and omissions of automotive parts.
[0028] VII. This error-proof automotive parts welding device utilizes the extension of the hydraulic cylinder's telescopic end to push the air pump downwards, causing the right-angle air tube to move downwards as well. The air port at the bottom of the right-angle air tube is brought into contact with the top of the automotive parts, and the air pump draws air out of the right-angle air tube. The negative pressure created inside the right-angle air tube lifts the automotive parts. The retraction of the hydraulic cylinder's telescopic end then lifts the air pump and the automotive parts, thereby unloading the automotive parts for subsequent batch processing.
[0029] 8. This error-proof automotive parts welding device uses the contact between the surface of the semi-circular elastic plate and the surface of the force-bearing wheel to generate a pushing force on the force-bearing wheel and the slider at the bottom of the right-angle frame. Combined with the fact that the elastic force of the semi-circular elastic plate is greater than the elastic force of the return spring, the right-angle frame moves the lifted automotive parts together to the side away from the rotating worktable, and the return spring is compressed. When the automotive parts move out of the L-shaped hook, the extension of the telescopic end of the hydraulic cylinder lowers the automotive parts onto the conveyor belt, and the air pump is turned off, allowing the automotive parts to fall onto the conveyor belt for unloading.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0040] First embodiment, such as Figures 1 to 4 As shown, the present invention provides a technical solution:
[0041] A welding apparatus for preventing errors and omissions in automotive parts, comprising:
[0042] The machine body 1, and the base 2 fixedly installed at the bottom of the machine body 1, and the rotary feeding mechanism 3 installed at the middle of the top of the machine body 1;
[0043] The machining mechanism 4 is used to weld automotive parts, and the machining mechanism 4 is installed on the side of the surface of the body 1.
[0044] The processing mechanism 4 includes a controller 41, a mechanical arm 42, and a supporting arm 43. The controller 41 is fixedly installed on the side of the surface of the machine body 1. The mechanical arm 42 is installed at the center of the top of the controller 41. The supporting arm 43 is installed at the top of the mechanical arm 42. A welder 44 is installed on the surface of the supporting arm 43 away from the mechanical arm 42. A first camera 45 is fixedly installed on the side of the surface of the welding device 44. Equipped with a second camera 46, a support column 47 is fixedly installed on the top side of the controller 41. A roller 48 is rotatably installed on the top of the support column 47. An annular extension edge 49 is fixedly connected to the top edge of the roller 48. By controlling the mechanical arm 42 and the support arm 43 through the controller 41, and under the linkage of the mechanical arm 42 and the support arm 43, the welder 44 can be moved and its position adjusted, so as to facilitate the welding of automotive parts in different positions through the welder 44.
[0045] 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.
[0046] The support column 47 is installed vertically, and the annular extension edge 49 and the roller 48 are concentric circles.
[0047] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 6 As shown:
[0048] The rotary feeding mechanism 3 includes a rotating worktable 31. The central axis of the bottom of the rotating worktable 31 is rotatably mounted at the midpoint between the top of the machine body 1. A material trough 32 is provided on the side of the top of the rotating worktable 31. A right-angled groove 33 is provided on the inner side of the material trough 32. A semi-circular elastic piece 34 is fixedly connected to the edge of the surface of the rotating worktable 31 near the opening of the material trough 32. A clamping block 35 is fixedly connected to the inner side of the semi-circular elastic piece 34. A curved spring piece 36 is fixedly connected to the bottom of the semi-circular elastic piece 34. The curved spring piece 36 is located away from the semi-circular elastic piece 34. One end of the circular elastic sheet 34 is fixedly connected to an L-shaped hook 37. The operator controls the robotic arm of the external equipment to place the automotive part blank that needs to be welded into the material tank 32. The automotive part blank is embedded between the L-shaped hook 37 and the clamping block 35, which can initially position the automotive part blank so that it will not move or fall off at will. Then, the rotating worktable 31 is turned on to start working. By rotating the rotating worktable 31 clockwise, the automotive part blank can be fed to the bottom of the welding machine 44.
[0049] The first camera 45 captures images of the automotive part blanks 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 status of the automotive part blanks in the material trough 32 at the top edge of the rotating worktable 31. When there are no automotive part blanks in the material trough 32, the external robotic arm will refill the material to prevent any omissions. When there are automotive part blanks in the material trough 32, the position of the automotive part blanks can be accurately located. As the rotating worktable 31 continues to rotate, when the automotive part blanks rotate to a position directly below the welder 44, the rotating worktable 31 stops working, and the automotive part blanks stop moving so that the welder 44 can perform welding operations in sequence.
[0050] There are five material troughs 32, which are evenly distributed on the top side of the rotating worktable 31. The semi-circular elastic sheet 34 is installed at the same height as the material troughs 32. When the rotating worktable 31 rotates, it will drive the semi-circular elastic sheet 34 to rotate together. The surface of the semi-circular elastic sheet 34 is in contact with the surface of the roller 48, so that the semi-circular elastic sheet 34 is pushed by the roller 48. The roller 48 rolls the semi-circular elastic sheet 34, so that the semi-circular elastic sheet 34 is compressed and deformed elastically. This allows the clamping block 35 to be in contact with the automotive part blank in the material trough 32, so that the automotive part blank can be clamped and fixed. After being squeezed, the clamping block 35 deforms and fills the gap between the inner side of the semi-circular elastic sheet 34 and the surface of the automotive part blank, so as to clamp the automotive part blank stably.
[0051] The L-shaped hook 37 is slidably installed between the right-angled groove 33 and the clamping block 35 is made of rubber. The curved spring piece 36 is installed directly below the clamping block 35. After the welder 44 finishes welding the automotive part blank, the welder 44 can be lifted again by the linkage of the mechanical arm 42 and the supporting arm 43. The welded automotive part is removed by rotating the worktable 31 clockwise. The pressure of the roller 48 on the semi-circular elastic piece 34 disappears. Under the elastic force of the semi-circular elastic piece 34, the semi-circular 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 be used to apply a pulling force to the automotive part, causing the automotive part to move outward.
[0052] After the rotating worktable 31 removes the automotive parts, the second camera 46 captures images of the removed automotive parts and transmits the information collected by the second camera 46 to the controller 41 in the form of electrical signals. The controller 41 can then process and analyze the signals. When the automotive parts have been welded, the rotating worktable 31 can continue to rotate clockwise. When the automotive parts have not been welded, the rotating worktable 31 can be rotated counterclockwise to return to the welding position, and the welding machine 44 can be used to re-weld the parts, thus avoiding welding errors and omissions of automotive parts.
[0053] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 1 to 8 As shown:
[0054] A material unloading mechanism 5 is installed on the side of the surface of the machine body 1. The material unloading mechanism 5 includes a support frame 51, which is fixedly installed to the side of the surface of the machine body 1 by screws. A drive roller 52 is rolled on one end of the top of the support frame 51, and a driven roller 53 is rolled on the top of the support frame 51 away from the drive roller 52. A conveyor belt 54 is installed between the drive 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 near the drive roller 52. A material picking component 56 is installed on the top of the support frame 51 near the driven roller 53. As the worktable 31 rotates, the already welded steam... When the car parts are rotated clockwise to be directly below the air pump 565, the operation of the rotating worktable 31 can be paused again, and the hydraulic cylinder 564 can be activated. By extending the telescopic end of the hydraulic cylinder 564, the air pump 565 can be pushed downward, causing the right-angle air pipe 566 to move downward as well. The air port at the bottom of the right-angle air pipe 566 is brought into contact with the top of the car parts, and the air pump 565 sucks out the air inside the right-angle air pipe 566. The negative pressure created inside the right-angle air pipe 566 can lift the car parts. By retracting the telescopic end of the hydraulic cylinder 564, the air pump 565 and the car parts are lifted, and the car parts are unloaded.
[0055] One end of the driving roller 52 is fixedly installed to the output end of the servo motor 55 via a coupling, and the driven roller 53 is installed at the same height as the driving roller 52.
[0056] The material handling assembly 56 includes a strip guide rail 561, which is fixedly installed on the top of the support frame 51 and near one end of the driven roller 53. A right-angle frame 562 is slidably mounted on the surface of the strip guide rail 561 via 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 installed on the side of the top of the right-angle frame 562. An air pump 565 is fixedly connected to the telescopic end of the hydraulic cylinder 564. 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 away from the return spring 563. A force-bearing wheel 568 is rolled on the bottom end of the connecting square rod 567 and away from the slider end at the bottom of the right-angle frame 562 via a pin.
[0057] Two strip guide rails 561 are installed symmetrically along the central axis of the conveyor belt 54. The hydraulic cylinder 564 is installed vertically, and the air inlet of the right-angle air pipe 566 faces downwards. The return spring 563 is installed in the middle of the inside of the strip guide rail 561. After the bottom end of the right-angle air pipe 566 has finished picking up the car part, the rotating worktable 31 drives the semi-circular elastic plate 34 to rotate again. The surface of the semi-circular elastic plate 34 contacts the surface of the force-receiving wheel 568, causing the force-receiving wheel 568 to receive a pushing force. Furthermore, with the connection of the connecting square rod 567, the slider at the bottom of the right-angle frame 562 receives a pushing force. Combined with the fact that the elastic force of the semi-circular elastic plate 34 is greater than the elastic force of the return spring 563, the right-angle frame 562 moves the lifted car part away from the rotating worktable 31. The return spring... When the car parts are compressed and moved above the L-shaped hook 37, the extension of the telescopic end of the hydraulic cylinder 564 lowers the car parts onto the conveyor belt 54. The air pump 565 is then turned off, allowing the car parts to fall onto the conveyor belt 54 for unloading. The servo motor 55 is then activated, and its output drives the active roller 52 to roll. With the support of the driven roller 53, the conveyor belt 54 rotates, allowing the car parts to be removed. As the semi-circular elastic plate 34 separates from the force-bearing wheel 568, the pushing force of the semi-circular elastic plate 34 on the force-bearing wheel 568 disappears. Under the elastic force of the return spring 563, the right-angle frame 562 drives the air pump 565 to move towards the side closer to the rotating worktable 31 for reset, facilitating the subsequent unloading of the car parts.
[0058] In use, the operator first controls the robotic arm of the external equipment to place the automotive part blank to be welded into the material trough 32 between the robotic arm 42 and the support frame 51. The automotive part blank is embedded between the L-shaped hook 37 and the clamping block 35, which can initially position the automotive part blank so that it will not move or fall off at will. Then, the rotating worktable 31 is turned on to start working. By rotating the rotating worktable 31 clockwise, the automotive part blank can be fed to the bottom of the welder 44.
[0059] At this time, the first camera 45 captures information on the automotive part blanks 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 status of the automotive part blanks in the material trough 32 at the top edge of the rotating worktable 31. When there are no automotive part blanks in the material trough 32, the external robotic arm will refill the material to prevent any omissions. When there are automotive part blanks in the material trough 32, the position of the automotive part blanks can be accurately located. As the rotating worktable 31 continues to rotate, when the automotive part blanks rotate to the position directly below the welder 44, the operation of the rotating worktable 31 is paused and the automotive part blanks stop moving.
[0060] Simultaneously, by utilizing the contact between the surface of the semi-circular elastic sheet 34 and the surface of the roller 48, the semi-circular elastic sheet 34 is pushed by the roller 48. The roller 48 rolls the semi-circular elastic sheet 34, causing it to deform elastically under pressure. This allows the clamping block 35 to contact the automotive part blank in the material trough 32, thus clamping and fixing the automotive part blank. After being squeezed, the clamping block 35 deforms, filling the gap between the inner side of the semi-circular elastic sheet 34 and the surface of the automotive part blank, thus clamping the automotive part blank stably.
[0061] Furthermore, 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 moved and its position adjusted, so as to facilitate the welding of automotive parts in different positions through the welder 44.
[0062] After the welding machine 44 finishes welding the automotive part blank, the welding machine 44 can be lifted again by the linkage of the mechanical arm 42 and the supporting arm 43. The welded automotive part is removed by rotating the worktable 31 clockwise. The squeezing force of the semi-circular elastic plate 34 by the roller 48 disappears. Under the elastic force of the semi-circular elastic plate 34, the semi-circular elastic plate 34 drives the curved elastic plate 36 and the L-shaped pull hook 37 to move outward to reset. The L-shaped pull hook 37 can then apply a pulling force to the automotive part, causing the automotive part to move outward.
[0063] After the rotating worktable 31 removes the automotive parts, the second camera 46 captures images of the removed automotive parts and transmits the information collected by the second camera 46 to the controller 41 in the form of electrical signals. The controller 41 can then process and analyze the signals. When the automotive parts have been welded, the rotating worktable 31 can continue to rotate clockwise. When the automotive parts have not been welded, the rotating worktable 31 can be rotated counterclockwise to return to the welding position and re-weld using the welder 44 to avoid welding errors and omissions in the automotive parts.
[0064] Furthermore, as the rotating worktable 31 rotates the already welded automotive parts clockwise to directly below the air pump 565, the worktable 31 can be paused again, and the hydraulic cylinder 564 can be activated. By extending the telescopic end of the hydraulic cylinder 564, the air pump 565 can be pushed downward, causing the right-angle air pipe 566 to move downward as well. The air port at the bottom of the right-angle air pipe 566 is brought into contact with the top of the automotive parts, and the air pump 565 draws air out, creating a negative pressure inside the right-angle air pipe 566, which lifts the automotive parts. By retracting the telescopic end of the hydraulic cylinder 564, the air pump 565 and the automotive parts are lifted, and the automotive parts are unloaded.
[0065] After the bottom end of the right-angle air pipe 566 has finished picking up the car part, the rotating worktable 31 drives the semi-circular elastic plate 34 to rotate again. The surface of the semi-circular elastic plate 34 contacts the surface of the force-receiving wheel 568, causing the force-receiving wheel 568 to receive a pushing force. Furthermore, under the connection of the connecting square rod 567, the slider at the bottom end of the right-angle frame 562 receives a pushing force. Combined with the fact that the elastic force of the semi-circular elastic plate 34 is greater than the elastic force of the return spring 563, the right-angle frame 562 moves the lifted car part away from the rotating worktable 31, and the return spring 563 is compressed. When the car part moves out of the L-shaped hook 37, the extension of the telescopic end of the hydraulic cylinder 564... The car parts are placed onto the conveyor belt 54, and the air pump 565 is turned off, allowing the car parts to fall onto the conveyor belt 54 for unloading. The servo motor 55 is then turned on, and its output drives the active roller 52 to roll. With the support of the driven roller 53, the conveyor belt 54 rotates, removing the car parts. As the semi-circular elastic plate 34 separates from the force-bearing wheel 568, the pushing force of the semi-circular elastic plate 34 on the force-bearing wheel 568 disappears. Under the elastic force of the return spring 563, the right-angle frame 562 drives the air pump 565 to move towards the side closer to the rotating worktable 31 for reset, facilitating the subsequent unloading of the car parts.
