Description

Technical Field

[0001] The present invention relates to the technical field of distribution box conveying, and particularly to a conveying device for detecting a distribution box welding production line and a using method thereof. Background Technique

[0002] In electrical and electronic equipment, metal shell distribution boxes usually require welding processes to ensure structural strength, electrical conductivity or sealing performance. Generally, laser welding or resistance welding is used. Through welding, the metal shell distribution boxes can better withstand vibration and impact. In the distribution box welding production line, a large number of distribution boxes need to be welded. In the traditional detection link of the distribution box welding production line, manual conveying is often relied on. To improve the detection efficiency, conveyors for loading or unloading are usually used to automatically convey the distribution boxes; Since during the welding process, it is necessary to accurately weld each component together. During the conveying of the distribution box by using the traditional belt conveying mechanism, it is easy to cause slight displacement of the distribution box and the welding components due to vibration or deviation of the conveying angle, resulting in slight shaking of the distribution box during the conveying process. Moreover, it is difficult to correct the deviation of the distribution box in the detection area, resulting in deviation of the positions of a batch of distribution boxes in the detection area and affecting the accuracy of the detection results.

[0006] As a further solution of the present invention, two support rods are fixedly connected to the outer wall of the clamping sleeve, and the included angle between the two support rods is 90 degrees. At the bottom ends of the two opposite support rods, a rolling rod is rotatably installed. A U-shaped fixing frame is fixedly connected to the support plate. Slideways are respectively opened on both sides of the fixing frame. A cross plate is slidably connected through the two slideways. The cross plate is lapped on the top of the inner wall of the support plate. Buffer springs are respectively fixedly connected to both sides of the bottom of the cross plate, and the bottom ends of the two buffer springs are fixed on both sides of the support plate. The telescopic ends of two electro-hydraulic rods penetrate and slide in the fixing frame and are fixed to the top of the cross plate.

[0007] As a further solution of the present invention, the conveying assembly includes two side plates. Two driving wheels are rotatably connected between the two side plates through bushing sleeves. A conveyor belt is sleeved outside the two driving wheels. One end of one of the driving wheels penetrates through the side plate and is fixed with a motor, and the motor is fixed outside the side plate. A plurality of support wheels are lapped on the top of the inner wall of the conveyor belt, and both ends of the support wheels are rotatably connected between the two side plates through bushing sleeves.

[0008] As a further solution of the present invention, the adjusting assembly includes a bidirectional lead screw. Limiting bearings are respectively sleeved at both ends of the bidirectional lead screw, and the two limiting bearings are respectively clamped in front of and behind the workbench. Nuts are respectively threadedly connected to both sides of the outer wall of the bidirectional lead screw, and a support plate is fixed on the nut. The support plate is fixed to the bottom of the side plate in the conveying assembly.

[0009] As a further solution of the present invention, the limiting assembly includes a sliding rod. Both ends of the sliding rod are fixedly connected to the front and rear sides inside the workbench. Sliding sleeves are respectively sleeved on both sides of the outer wall of the sliding rod, and the top of the sliding sleeve is fixed to the bottom of the side plate in the conveying assembly.

[0010] As a further solution of the present invention, the blanking assembly includes a U-shaped frame. A plurality of guide wheels are rotatably installed on the inner wall of the U-shaped frame. Three sliding seats are fixedly connected to the bottom of the U-shaped frame. Slide holes are respectively opened on the side plate at positions corresponding to the three sliding seats. The sliding seats are designed in a T shape and penetrate and slide in the slide holes. Two support springs are fixedly connected between the sliding seat and the inner wall of the slide hole.

[0011] A method for using a conveying device for testing a distribution box welding production line, the method comprising the following steps: When inspecting the distribution box after welding, place the distribution box on one side of the two conveyor assemblies so that the front and rear sides of the bottom of the distribution box are in contact with the two conveyor belts, and the middle part of the bottom of the distribution box is in contact with the tops of multiple support rollers. When limiting the front and rear sides of the distribution box, turn the handle to drive the bidirectional lead screw to rotate inside the two limit bearings, thereby improving the rotation stability of the bidirectional lead screw on the workbench, and the two nuts outside the bidirectional lead screw will move and drive the two supporting plates to approach each other, and the two supporting plates will respectively drive the two side plates to approach each other, and the side plates will drive the U-shaped frame to approach the distribution box through the slide seat, so that the guide wheel in the U-shaped frame is in contact with the distribution box, and the distribution box is squeezed by the two guide wheels to move the distribution box. The box is pushed to the center of the workbench, and then the front and rear sides of the distribution box are limited to prevent the distribution box from deviating from the angle during transportation. In the process of squeezing the distribution box by the guide wheel, the U-shaped frame is subjected to force to drive the slide to slide in the slide hole, and the T-shaped slide is limited by the slide hole, thereby improving the stability of the U-shaped frame and the slide in the horizontal movement, and the slide will not separate from the slide hole. The slide is supported by the elastic force of the support spring, so that the U-shaped frame drives the guide wheel to flexibly support the distribution box, preventing the distribution box from being deformed due to excessive clamping force, and playing the role of supporting and buffering the distribution box. In addition, by synchronously adjusting the distance between the two U-shaped frames, it can meet the limited transportation requirements of distribution boxes of different specifications. When the distribution box is being transported, the motor in the conveying assembly is controlled to work, and the output shaft of the motor drives one of the transmission wheels to rotate, and the transmission wheel drives the transmission wheel on the other side to rotate through the conveyor belt, so that the conveyor belt drives the distribution box on the workbench to approach the detection bracket. At this time, the conveyor belt drives the guide wheels on the front and rear sides to rotate, and cooperates with the support rollers below to support the distribution box, thereby reducing the friction when the distribution box moves, and the support wheels support the top of the inner wall of the conveyor belt, thereby improving the stability of the horizontal transportation of the distribution box. After the distribution box is transported to the bottom of the detection bracket, the motor is controlled to stop working, so that the conveyor belt no longer drives the distribution box to move; When rectifying the power distribution box in the detection area of the detection bracket, control the two electro-hydraulic rods to extend and drive the rectifying assembly to move downward, so that the support plate in the rectifying assembly drives the rotating shaft to move downward. The rotating shaft drives multiple support rods and two rolling rods to move downward through two clamping sleeves, so that two mutually approaching rolling rods in the two rectifying assemblies contact both sides of the power distribution box. As the support plate continues to move downward, the current two rolling rods drive the rotating shaft to rotate within the support plate through the support rods and the clamping sleeves. At the same time, the clamping sleeve drives the other rolling rod to rotate and contact the side of the power distribution box, so that two mutually separated rolling rods in the two rectifying assemblies push the power distribution box to move horizontally, and the power distribution box is pushed to the center of the detection area in the detection bracket until the power distribution box stops moving. Therefore, the power distribution box is rectified and locked at multiple points, and the guide wheels on the front and rear sides of the power distribution box are used to support and limit it, so as to achieve the purpose of calibrating the center of the power distribution box. During the conveying and detection process of a batch of power distribution boxes, the positions of all power distribution boxes in the detection area have no deviation; During the downward movement of the rectifying assembly, since the telescopic end of the electro-hydraulic rod penetrates through the fixing frame and is fixed to the cross plate, the cross plate supports the fixing frame. The fixing frame drives the two lower rolling rods to move downward through the support plate and contact the power distribution box. When the two rolling rods deflect and rectify and limit the top and side of the power distribution box, the rolling rods will be compressed and push up the rotating shaft through the support rods and the clamping sleeves. The rotating shaft then squeezes two buffer springs and the fixing frame upward through the support plate. Since the cross plate is fixed to the telescopic end of the electro-hydraulic rod, the fixing frame slides upward outside the telescopic end of the electro-hydraulic rod, and cooperates with the elastic force of the two buffer springs to support the support plate. The force received by the support plate acts on the lower rolling rods, playing a role in supporting and buffering the two rolling rods, preventing the welded power distribution box from deforming during the downward pressure of the rolling rods, and playing a role in protecting the power distribution box; After detecting the power distribution box by installing a detection mechanism on the detection bracket, control the two electro-hydraulic rods to contract, so that the electro-hydraulic rods drive the rectifying assembly to move upward, and the rolling rods in the rectifying assembly move upward. During the upward movement of the rolling rods, the clamping sleeve is rotated by the acting force of the torsion spring, so that the clamping sleeve drives the rolling rod to return to the initial position through the support rod. When the two rolling rods on the same side are completely separated from the power distribution box, the central axes of the two rolling rods are in the same horizontal position, which is convenient for the next rectifying and limiting work of the turnover box. Secondly, control the motor to continue working, so that the conveyor belt sends the detected power distribution box out of the detection area in the detection bracket, and at the same time, the power distribution box to be detected is transferred into the detection bracket.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention squeezes the distribution box through two guide wheels, pushes the distribution box to the center of the workbench, and then limits the front and rear sides of the distribution box to prevent the distribution box from deviating in angle during transportation. Control the two electro-hydraulic rods to extend and drive the rectifying assembly to move downward, so that the support plate in the rectifying assembly drives the rotating shaft to move downward. The rotating shaft drives a plurality of support rods and two rolling rods to move downward through two clamping sleeves, so that two mutually approaching rolling rods in the two rectifying assemblies contact the two sides of the distribution box. As the support plate continues to move downward, the first two rolling rods drive the rotating shaft to rotate in the support plate through the support rods and clamping sleeves. At the same time, the clamping sleeve drives the other rolling rod to rotate and contact the side of the distribution box, so that two mutually remote rolling rods in the two rectifying assemblies push the distribution box to move horizontally, and push the distribution box to the center of the detection area in the detection bracket until the distribution box stops moving. Therefore, the distribution box is rectified and locked at multiple points, and is supported and limited by the guide wheels on the front and rear sides of the distribution box, achieving the purpose of calibrating the center of the distribution box. During the transportation and detection of a batch of distribution boxes, the positions of all distribution boxes in the detection area have no deviation, ensuring the accuracy of the detection results; 2. When the present invention limits the front and rear sides of the distribution box, rotate the turning handle to drive the bidirectional lead screw to rotate inside the two limit bearings, improving the stability of the bidirectional lead screw rotating on the workbench. And the two nuts outside the bidirectional lead screw will move and drive the two supporting plates to approach each other. The two supporting plates respectively drive the two side plates to approach each other. The side plates drive the U-shaped frame to approach the distribution box through the sliding seat, so that the guide wheels in the U-shaped frame contact the distribution box. Squeeze the distribution box through the two guide wheels, push the distribution box to the center of the workbench for limiting, and cooperate with the elastic force of the support spring to support the sliding seat, so that the U-shaped frame drives the guide wheels to flexibly support the distribution box, preventing the distribution box from being deformed due to excessive clamping force, playing a role in supporting and buffering the distribution box. Moreover, by synchronously adjusting the distance between the two U-shaped frames, it meets the requirements of limiting and transporting distribution boxes of different specifications.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0017] Please refer to Figures 1-8 , the present invention provides a technical solution: A conveying device for detecting a distribution box welding production line, comprising a workbench 1. A support frame 2 is fixedly connected to the bottom of the workbench 1. A detection support 3 is fixedly connected to the middle of the workbench 1. Two electric hydraulic rods 4 are respectively penetrated and fixed on both sides of the detection support 3. The bottom ends of the two electric hydraulic rods 4 on the same side are fixedly connected with a deviation rectifying component 5; below the deviation rectifying component 5, there are two conveying components 6. There are two partition plates 7 between the two conveying components 6. The two partition plates 7 are fixed on the workbench 1, and a plurality of support rollers 8 are rotatably installed between the two partition plates 7. During the process of the conveying component 6 conveying the distribution box, the support rollers 8 below cooperate to support the distribution box, reduce the friction when the distribution box moves, and improve the stability of the distribution box movement; In the middle of the lower part of the two conveying components 6, an adjusting component 9 is fixedly connected. The adjusting component 9 is penetrated and installed on the workbench 1; on both sides of the adjusting component 9, there are respectively limit components 10. The two ends of the limit component 10 are respectively fixed on the front and rear sides of the inner wall of the workbench 1. The top of the limit component 10 is fixed to the bottom of the two conveying components 6; As a further solution of the present invention, the deviation rectifying component 5 includes a support plate 501. The support plate 501 is designed in a U shape and two support bearings 503 are respectively clamped on both sides. A rotating shaft 502 is sleeved in the two support bearings 503. The support bearings 503 support and limit the rotating shaft 502, and improve the stability of the rotating shaft 502 driven by the sleeve 504 to rotate. On both sides of the outer wall of the rotating shaft 502, there are respectively fixedly connected with sleeves 504. A torsion spring 507 is fixedly connected between the sleeve 504 and the inner wall of the support plate 501. The torsion spring 507 is sleeved outside the rotating shaft 502; on the outer wall of the sleeve 504, there are fixedly connected with two support rods 505. The included angle between the two support rods 505 is ninety degrees, and the bottom ends of the two opposite support rods 505 are rotatably installed with rolling rods 506; During work, the two mutually approaching rolling rods 506 are in contact with both sides of the distribution box. As the support plate 501 continues to move downwards, the current two rolling rods 506 drive the rotating shaft 502 to rotate in the support plate 501 through the support rods 505 and the sleeve 504. At the same time, the sleeve 504 drives the other rolling rod 506 to rotate and be in contact with the side surface of the distribution box, so that the two mutually distant rolling rods 506 in the two deviation rectifying components 5 push the distribution box to move horizontally, and push the distribution box to the center of the detection area in the detection support 3. The distribution box is rectified and locked at multiple points, so that the position of the distribution box in the detection area will not deviate; During the process of the rolling rod 506 moving upwards, the torsion spring 507 drives the sleeve 504 to rotate back through its acting force, so that the sleeve 504 drives the rolling rod 506 to return to the initial position through the support rod 505. When the two rolling rods 506 on the same side are completely separated from the distribution box, the central axes of the two rolling rods 506 are in the same horizontal position, so as to facilitate the next deviation rectifying and limiting work of the turnover box.

[0018] A U-shaped fixing bracket 508 is fixedly connected to the support plate 501. Slideways 509 are respectively formed on both sides of the fixing bracket 508.

Two buffer springs 511 are respectively fixedly connected to both sides of the bottom of the cross plate 510. The bottom ends of the two buffer springs 511 are fixed on both sides of the support plate 501. The telescopic ends of the two electro-hydraulic rods 4 penetrate and slide in the fixing bracket 508 and are fixed to the top of the cross plate 510; During operation, the roller 506 will be pressed and the rotating shaft 502 will be jacked up through the support rod 505 and the ferrule 504. The rotating shaft 502 will then upwardly press the two buffer springs 511 and the fixing bracket 508 through the support plate 501. Since the cross plate 510 is fixed to the telescopic end of the electro-hydraulic rod 4, the fixing bracket 508 slides upward on the outside of the telescopic end of the electro-hydraulic rod 4, and cooperates with the elastic force of the two buffer springs 511 to support the support plate 501. The force received by the support plate 501 acts on the lower roller 506, playing a role in supporting and buffering the two rollers 506 and preventing the welded distribution box from being deformed during the downward pressing of the roller 506.

[0019] As a further solution of the present invention, the conveying assembly 6 includes two side plates 601.

The motor 605 is fixed outside the side plate 601; A plurality of support wheels 604 are lapped on the top of the inner wall of the conveyor belt 603. Both ends of the support wheels 604 are rotatably connected between the two side plates 601 through bushings; During operation, the driving wheel 602 drives the other driving wheel 602 to rotate through the conveyor belt 603, so that the conveyor belt 603 drives the distribution box to approach the detection bracket 3 on the workbench 1. At this time, the conveyor belt 603 drives the guide wheels 112 on the front and rear sides to rotate, and cooperates with the lower support roller 8 to support the distribution box, reducing the friction when the distribution box moves. Moreover, the support wheels 604 support the top of the inner wall of the conveyor belt 603, thereby improving the stability of the horizontal conveying of the distribution box.

The two support plates 903 are respectively fixed to the bottoms of the side plates 601 in the two conveying assemblies 6. One end of the bidirectional lead screw 901 penetrates the workbench 1 and is fixedly connected with a turning handle 905; During operation, the handle 905 is rotated to drive the bidirectional screw rod 901 to rotate inside the two limit bearings 902, thereby improving the stability of the bidirectional screw rod 901 in rotating on the workbench 1; the two nuts 904 outside the bidirectional screw rod 901 will move and drive the two support plates 903 to approach each other, and the two support plates 903 will respectively drive the two conveying components 6 to approach or move away from each other, so as to adjust the distance between the two conveying components 6 according to the specifications of the distribution box.

[0021] As a further solution of the present invention, the limiting assembly 10 includes a slide rod 101, the two ends of which are fixedly connected to the front and rear sides of the workbench 1, and the two sides of the outer wall of the slide rod 101 are respectively sleeved with a slide sleeve 102, and the top of the slide sleeve 102 is fixedly connected to the bottom of the side plate 601 in the conveying assembly 6; During operation, the conveying component 6 will move and drive the sleeve 102 to move outside the slide rod 101. The slide rod 101 will limit the sleeve 102, which will support and limit the conveying component 6 in the horizontal direction, thereby improving the stability of the conveying component 6 in driving the distribution box to move.

[0022] As a further solution of the present invention, a lifting assembly 11 is overlapped on the conveying assembly 6. The lifting assembly 11 includes a U-shaped frame 111. A plurality of guide wheels 112 are rotatably mounted on the inner wall of the U-shaped frame 111. Three slides 113 are fixedly connected to the bottom of the U-shaped frame 111. Slide holes 606 are respectively opened at positions corresponding to the three slides 113 on the side plate 601. The slides 113 are T-shaped and slide through the slide holes 606. Two support springs 114 are fixedly connected between the slides 113 and the inner wall of the slide holes 606. During operation, the two supporting plates 903 respectively drive the two side plates 601 to approach each other, and the side plates 601 drive the U-shaped frame 111 to approach the distribution box through the slide 113, so that the guide wheels 112 in the U-shaped frame 111 contact the distribution box. The two guide wheels 112 squeeze the distribution box and push it to the center of the workbench 1, thereby limiting the front and rear sides of the distribution box to prevent the distribution box from deviating from the angle during transportation; When the guide wheel 112 is squeezing the distribution box, the U-shaped frame 111 is subjected to force and drives the slide 113 to slide in the slide hole 606. The slide 113 with a T-shaped design is limited by the slide hole 606, thereby improving the stability of the horizontal movement of the U-shaped frame 111 and the slide 113, and the slide 113 will not separate from the slide hole 606. The elastic force of the support spring 114 supports the slide 113, so that the U-shaped frame 111 drives the guide wheel 112 to flexibly support the distribution box, preventing the distribution box from being deformed due to excessive clamping force, and playing a role in supporting and buffering the distribution box.

[0023] A method for using a conveying device for testing a distribution box welding production line, the method comprising the following steps: When inspecting the distribution box after welding, the distribution box is placed on one side of the two conveying assemblies 6, so that the front and rear sides of the bottom of the distribution box are in contact with the two conveyor belts 603, and the middle part of the bottom of the distribution box is in contact with the top of multiple support rollers 8. When limiting the front and rear sides of the distribution box, the handle 905 is rotated to drive the two-way screw rod 901 to rotate inside the two limit bearings 902, thereby improving the rotation stability of the two-way screw rod 901 on the workbench 1, and the two nuts 904 outside the two-way screw rod 901 will move and drive the two supporting plates 903 to approach each other, and the two supporting plates 903 will respectively drive the two side plates 601 to approach each other, and the side plates 601 will drive the U-shaped frame 111 to approach the distribution box through the slide 113, so that the guide wheel 112 in the U-shaped frame 111 is in contact with the distribution box, and the distribution box is squeezed by the two guide wheels 112. The U-shaped frame 111 is moved to the center of the workbench 1, and then the front and rear sides of the frame are limited to prevent the frame from deviating from the angle during transportation. In the process of squeezing the frame, the guide wheel 112 drives the slide 113 to slide in the slide hole 606. The slide hole 606 limits the T-shaped slide 113, thereby improving the stability of the U-shaped frame 111 and the slide 113 in horizontal movement, and the slide 113 will not separate from the slide hole 606. The slide 113 is supported by the elastic force of the support spring 114, so that the U-shaped frame 111 drives the guide wheel 112 to flexibly support the frame, preventing the frame from being deformed due to excessive clamping force, and playing the role of supporting and buffering the frame. In addition, the distance between the two U-shaped frames 111 is synchronously adjusted to meet the requirements of limited transportation of distribution boxes of different specifications. When the distribution box is being transported, the motor 605 in the transport assembly 6 is controlled to work, and the output shaft of the motor 605 drives one of the transmission wheels 602 to rotate, and the transmission wheel 602 drives the transmission wheel 602 on the other side to rotate through the conveyor belt 603, so that the conveyor belt 603 will drive the distribution box on the workbench 1 to approach the detection bracket 3. At this time, the conveyor belt 603 will drive the guide wheels 112 on the front and rear sides to rotate, and cooperate with the support rollers 8 below to support the distribution box, thereby reducing the friction when the distribution box moves, and the support wheel 604 supports the top of the inner wall of the conveyor belt 603, thereby improving the stability of the horizontal transportation of the distribution box. After the distribution box is transported to the bottom of the detection bracket 3, the motor 605 is controlled to stop working, so that the conveyor belt 603 no longer drives the distribution box to move; When rectifying the power distribution box in the detection area of the detection bracket 3, control the two electro-hydraulic rods 4 to extend and drive the rectifying assembly 5 to move downward, so that the support plate 501 in the rectifying assembly 5 drives the rotating shaft 502 to move downward. The rotating shaft 502 drives a plurality of support rods 505 and two rolling rods 506 to move downward through two clamping sleeves 504, so that the two mutually approaching rolling rods 506 in the two rectifying assemblies 5 contact both sides of the power distribution box. As the support plate 501 continues to move downward, the current two rolling rods 506 drive the rotating shaft 502 to rotate within the support plate 501 through the support rods 505 and the clamping sleeves 504. At the same time, the clamping sleeve 504 drives the other rolling rod 506 to rotate and contact the side of the power distribution box, so that the two mutually remote rolling rods 506 in the two rectifying assemblies 5 push the power distribution box to move horizontally, and the power distribution box is pushed to the center of the detection area within the detection bracket 3 until the power distribution box stops moving. Therefore, the power distribution box is rectified and locked at multiple points, and the guide wheels 112 on the front and rear sides of the power distribution box are used to support and limit it, so as to achieve the purpose of calibrating the center of the power distribution box. During the conveying and detection process of a batch of power distribution boxes, the positions of all power distribution boxes in the detection area have no deviation; During the downward movement of the rectifying group assembly 5, since the telescopic end of the electro-hydraulic rod 4 penetrates through the fixing frame and is fixed to the cross plate 510, the cross plate 510 supports the fixing frame 508. The fixing frame 508 drives the two lower rolling rods 506 to move downward through the support plate 501 and contact the power distribution box. When the two rolling rods 506 deflect and rectify and limit the top and side of the power distribution box, the rolling rods 506 will be compressed and push up the rotating shaft 502 through the support rods 505 and the clamping sleeves 504. The rotating shaft 502 squeezes the two buffer springs 511 and the fixing frame 508 upward through the support plate 501. Since the cross plate 510 is fixed to the telescopic end of the electro-hydraulic rod 4, the fixing frame 508 slides upward outside the telescopic end of the electro-hydraulic rod 4, and cooperates with the elastic force of the two buffer springs 511 to support the support plate 501. The force received by the support plate 501 acts on the lower rolling rods 506, playing a role in supporting and buffering the two rolling rods 506, preventing the power distribution box after welding from being deformed during the downward pressure of the rolling rods 506, and playing a role in protecting the power distribution box; After the distribution box is detected by installing a detection mechanism on the detection bracket 3, control the two electro-hydraulic rods 4 to contract, so that the electro-hydraulic rods 4 drive the rectification assembly 5 to move upward, causing the roller 506 in the rectification assembly 5 to move upward. During the upward movement of the roller 506, the torsion spring 507 drives the sleeve 504 to rotate, so that the sleeve 504 drives the roller 506 back to the initial position through the support rod 505. When the two rollers 506 on the same side are completely separated from the distribution box, the central axes of the two rollers 506 are in the same horizontal position, facilitating the next rectification and limiting work for the turnover box. Secondly, control the motor 605 to continue working, so that the conveyor belt 603 sends the detected distribution box out of the detection area in the detection bracket 3, and at the same time, the distribution box to be detected is transferred into the detection bracket 3.

A method of using a conveying device for detecting a distribution box welding production line, according to any one of claims 1-7, a conveying device for detecting a distribution box welding production line, characterized in that, The usage method includes the following steps: When performing the inspection work after the distribution box is welded, place the distribution box on one side of the two conveying components (6), so that the front and rear sides of the bottom of the distribution box are in contact with the two conveyor belts (603), and the middle part below the distribution box is in contact with the tops of the multiple support rollers (8). When limiting the front and rear sides of the distribution box, rotate the turning handle (905) to drive the bidirectional lead screw (901) to rotate inside the two limit bearings (902), improving the stability of the rotation of the bidirectional lead screw (901) on the workbench (1). The two nuts (904) outside the bidirectional lead screw (901) will move and drive the two support plates (903) to approach each other. The two support plates (903) will respectively drive the two side plates (601) to approach each other. The side plates (601) will drive the U-shaped frame (111) to approach the distribution box through the sliding seat (113), making the guide wheels (112) in the U-shaped frame (111) contact with the distribution box. Squeeze the distribution box through the two guide wheels (112), and push the distribution box to the center of the workbench (1), thereby limiting the front and rear sides of the distribution box, preventing the distribution box from deviating in angle during the conveying process. And during the process of the guide wheels (112) squeezing the distribution box, the U-shaped frame (111) is stressed and drives the sliding seat (113) to slide in the sliding hole (606). Limit the T-shaped sliding seat (113) through the sliding hole (606), improving the stability of the horizontal movement of the U-shaped frame (111) and the sliding seat (113), and the sliding seat (113) will not break away from the sliding hole (606). Cooperate with the elastic force of the support spring (114) to support the sliding seat (113), making the U-shaped frame (111) drive the guide wheels (112) to support the distribution box flexibly, preventing the distribution box from being deformed due to excessive clamping force, playing a role in supporting and buffering the distribution box. Moreover, by synchronously adjusting the distance between the two U-shaped frames (111), it can meet the requirements of limiting and conveying distribution boxes of different specifications; When conveying the distribution box, control the motor (605) in the conveying component (6) to work. The output shaft of the motor (605) drives one of the transmission wheels (602) to rotate. The transmission wheel (602) drives the transmission wheel (602) on the other side to rotate through the conveyor belt (603), so that the conveyor belt (603) will drive the distribution box to approach the inspection bracket (3) on the workbench (1). At this time, the conveyor belt (603) will drive the guide wheels (112) on the front and rear sides to rotate, and cooperate with the support rollers (8) below to support the distribution box, reducing the friction when the distribution box moves. Moreover, the support wheels (604) support the top of the inner wall of the conveyor belt (603), thereby improving the stability of the horizontal conveying of the distribution box. After the distribution box is conveyed to the lower part inside the inspection bracket (3), control the motor (605) to stop working, so that the conveyor belt (603) no longer drives the distribution box to move; When rectifying the distribution box in the detection area of the detection bracket (3), control the two electro-hydraulic rods (4) to extend and drive the rectifying assembly (5) to move downward, so that the support plate (501) in the rectifying assembly (5) drives the rotating shaft (502) to move downward. The rotating shaft (502) drives a plurality of support rods (505) and two roller rods (506) to move downward through two clamping sleeves (504), so that two mutually approaching roller rods (506) in the two rectifying assemblies (5) contact both sides of the distribution box. As the support plate (501) continues to move downward, the current two roller rods (506) drive the rotating shaft (502) to rotate within the support plate (501) through the support rods (505) and the clamping sleeves (504). At the same time, the clamping sleeve (504) drives the other roller rod (506) to rotate and contact the side of the distribution box, so that the two mutually remote roller rods (506) in the two rectifying assemblies (5) push the distribution box to move horizontally, and the distribution box is pushed to the center of the detection area in the detection bracket (3) until the distribution box stops moving. Therefore, the distribution box is rectified and locked at multiple points, and the guide wheels (112) on the front and rear sides of the distribution box are used to support and limit it, so as to achieve the purpose of calibrating the center of the distribution box. During the conveying and detection process of a batch of distribution boxes, the positions of all distribution boxes in the detection area have no deviation; During the downward movement of the rectifying group assembly (5), since the telescopic end of the electro-hydraulic rod (4) penetrates through the fixing frame and is fixed to the cross plate (510), the cross plate (510) supports the fixing frame (508), and the fixing frame (508) drives the two lower roller rods (506) to move downward and contact the distribution box through the support plate (501). When the two roller rods (506) deflect and rectify and limit the top and side of the distribution box, the roller rods (506) will be pressed and push up the rotating shaft (502) through the support rods (505) and the clamping sleeves (504). The rotating shaft (502) then squeezes two buffer springs (511) and the fixing frame (508) upward through the support plate (501). Since the cross plate (510) is fixed to the telescopic end of the electro-hydraulic rod (4), the fixing frame (508) slides upward outside the telescopic end of the electro-hydraulic rod (4), and cooperates with the elastic force of the two buffer springs (511) to support the support plate (501). The force received by the support plate (501) acts on the lower roller rods (506), playing a role in supporting and buffering the two roller rods (506), preventing the welded distribution box from deforming during the downward pressure of the roller rods (506), and playing a role in protecting the distribution box; After the distribution box is detected by installing a detection mechanism on the detection bracket (3), control the contraction of the two electro-hydraulic rods (4), so that the electro-hydraulic rods (4) drive the deviation rectification assembly (5) to move upward, and the roller (506) in the deviation rectification assembly (5) moves upward. During the upward movement of the roller (506), the collet (504) is driven to rotate by the acting force of the torsion spring (507), so that the collet (504) drives the roller (506) back to the initial position through the support rod (505). When the two rollers (506) on the same side are completely separated from the distribution box, the central axes of the two rollers (506) are in the same horizontal position, which is convenient for the next deviation rectification and limiting work of the turnover box. Secondly, control the motor (605) to continue working, so that the conveyor belt (603) sends the detected distribution box out of the detection area in the detection bracket (3), and at the same time, the distribution box to be detected is transferred into the detection bracket (3).
