[0014] The automatic assembly and processing equipment for distribution boxes proposed in this invention has the following advantages: The symmetrically arranged conveyor belt assembly enables the movement of the load-bearing box frame, which can be adjusted according to the box width. During the conveying movement, multiple rotating units are arranged in a row, allowing each unit to rotate the box frame 90 degrees. Since two sets of rotating units are arranged on each side of the welding unit, the box frame can be rotated 180 degrees before and after welding, allowing the orientation for alignment with the back panel to be determined using a first camera image. The box frame is clamped, fixed, raised, and rotated through a reversing structure, cooperating with the welding unit to achieve the desired assembly and processing of the distribution box. The welding of the four edges of the frame, along with the left-right movement and the lifting of the suction cups, enables the automatic pickup of the back panels stacked in the carrying unit. This facilitates the adsorption and unloading of the back panels, ensuring their stable fastening to the frame, thus completing the welding of the back panels to the frame on all four sides. The welded box is then fastened to the conveyor belt assembly and rotated 180 degrees again by two additional sets of flipping units, aligning the box with the detection unit. The detection unit fastens the top of the box, illuminating the interior and using a second camera to image and determine if external light sources are present at the weld points, thus identifying defects such as incomplete welds or burn-through. In summary, this invention has the following advantages:

[0015] 1. The symmetrically arranged conveyor belt assembly supports the movement of the box frame and can be adaptively adjusted according to the width of the box. This breaks the limitation of traditional equipment that can only adapt to a single specification of distribution box. It can meet the processing needs of distribution boxes of different sizes without the need to change special tooling, thereby improving the versatility and practicality of the equipment and reducing the equipment investment cost for enterprises.

[0016] 2. Before and after welding, the enclosure frame is rotated 180 degrees using two sets of flipping units. Each flipping unit precisely rotates the frame 90 degrees, with controllable flipping angle and accurate positioning. At the same time, the orientation is determined by the first camera imaging to ensure accurate alignment between the enclosure frame and the back panel. This also provides a guarantee for orientation matching in subsequent post-weld inspection, avoiding docking and welding errors caused by orientation deviations from the source.

[0017] 3. The reversing structure enables the integrated action of clamping, fixing, raising, and rotating the box frame. It works precisely with the welding unit to drive the frame to complete the automated welding of the four edges, replacing the manual operation of flipping, fixing, and adjusting the welding position, and avoiding positional deviations caused by manual operation. Moreover, the frame is firmly fixed during the welding process without shaking or shifting, effectively ensuring uniform weld gaps and no incomplete welds, thus improving the stability and consistency of welding quality.

[0018] 4. By utilizing the left and right movement of the reversing structure and the lifting action of the suction cup, the stacked back panels in the load-bearing unit can be automatically picked up and individually suctioned for unloading, avoiding the labor intensity and positioning deviation of manual handling of back panels; the suction cup suction unloading can ensure the smooth movement of the back panel and accurately fasten it to the box frame, providing a guarantee for the fit of subsequent four-sided welding and further improving the assembly and welding quality.

[0019] 5. After welding, the box is rotated 180 degrees by the flipping unit to precisely align with the detection unit. The detection unit is fastened on top of the box to form a closed, dark environment. Using the imaging of the second camera and the display judgment by the external light source, welding defects such as missing welds and weld penetration are accurately identified. Compared with traditional manual visual inspection, the inspection is more comprehensive and the results are more accurate. It can achieve full inspection instead of sampling inspection, which greatly improves the efficiency of quality control and prevents defective products from flowing into subsequent processes.

[0020] 6. This solution integrates the following processes into a single device: container conveying, first camera imaging to determine whether to flip and calibrate, side welding, automatic back panel pickup and docking, back panel four-sided welding, and precise post-welding inspection. All structural actions are linked and coordinated, eliminating the need for manual transfer and intervention between processes, effectively shortening the processing cycle and improving overall production efficiency. At the same time, it reduces problems such as bumps and scratches caused by manual intervention, ensuring the appearance and structural integrity of the container after processing.

[0021] 7. All core actions are controlled by mechanization and automation, such as the step-by-step precise flipping of the flipping unit, the multi-dimensional movement and fixation of the reversing structure, the single-board adsorption of the suction cup, and the closed imaging of the detection unit. Each operation has controllability and stability, avoiding the randomness and uncertainty of manual operation, greatly reducing the processing error rate and improving the overall processing yield.

Each pair of first electric slide rails 21 is provided with a first slide seat that can move relatively. One end of each pair of conveyor frames 22 is fixedly installed on the first slide seat of the first electric slide rail 21.

The first camera 25 mounted on its lower wall is opposite to the conveyor belt assembly 23 to realize imaging calibration during frame conveying. Two pairs of flipping units 26 are arranged and fixedly mounted on the upper walls of the left and right ends of the base 1, and are located between the two conveyor belt assemblies 23 to provide flipping action for the box frame.

[0035] As a preferred embodiment, the flipping unit 26 further includes a flipping frame 260, a first housing 261, a first motor 262, a second housing 263, a second motor 264, a first support plate 265, a second support plate 266, two pairs of fastening bolts 267, a pair of telescopic plates 268, a roller frame 269, and guide rollers 270; the flipping frame 260 is concave and is fixedly mounted on the upper wall of the base 1, and the first housing 261 is fixedly mounted on one end of the flipping frame 260. Motor 262 is fixedly installed inside the first housing 261, and the drive end of the first motor 262 movably passes through the front side wall of the first housing 261. A shaft 7 is provided at one end of the second housing 263, and the second housing 263 movably passes through the other end of the tilting frame 260 via the shaft 7. A second motor 264 is fixedly installed inside the second housing 263, and the drive end of the second motor 264 movably passes through the rear side wall of the second housing 263. The right rear side wall of the first pallet 265 is fixedly connected to the drive end of the first motor 262. On the moving end, pins are provided on both the front and rear side walls of one end of the second support plate 266. One end of the second support plate 266 is movably fitted into the middle of the right end of the first support plate 265 via the pins, and the pin on the front side of the second support plate 266 moves through the front side of the right end of the first support plate 265. The pin on the front side of the right end of the second support plate 266 is connected to the drive end of the second motor 264. The second support plate 266 and the first support plate 265 can be relatively perpendicular or parallel. Two pairs of fastening bolts 267 are respectively screwed onto the first support plate 265. Inside the front and rear side walls of the left end and the front and rear side walls of the other end of the second support plate 266, a pair of telescopic plates 268 are respectively movably inserted into the left end of the first support plate 265 and the other end of the second support plate 266, and the telescopic plates 268 are fixed by fastening bolts 267. One end of the roller frame 269 is fixedly set on the lower wall of the first support plate 265, and the other end of the roller frame 269 is inclined to the lower left. The guide roller 270 is movably set in the middle of the other end of the roller frame 269, and the guide roller 270 is located on the left side of the first support plate 265.

[0036] More specifically, this flipping unit 26 has two core working modes during equipment operation, which are used to perform corresponding actions in conjunction with the entire process of the equipment.

[0037] Passage mode: When the first camera 25 detects that the upper edge of the box frame is aligned with the back panel alignment side and no flipping or reversing is required, the second motor 264 starts and drives the second pallet 266 to rotate around the pin shaft to a state parallel to the first pallet 265, forming a flat channel that matches the conveying path. The box frame passes smoothly through the flipping unit with the conveyor belt assembly 23 and enters the next welding process without obstruction.

[0038] Flipping mode: When the first camera 25 detects that the orientation of the box frame does not match the back panel alignment side and needs to be reversed, the second motor 264 first drives the second pallet 266 to rotate to an L-shaped state perpendicular to the first pallet 265, forming a circumferential limit on the box frame that has been delivered to the position; then the first motor 262 starts, driving the first pallet 265 and the second pallet 266 to rotate 90 degrees around the coaxial axis, driving the box frame to complete a single 90-degree precise flip; after the box frame passes through two sets of flipping units 26 connected in series, it can complete a 180-degree overall reversal, achieving precise orientation alignment and ensuring the consistency of the benchmark for subsequent back panel docking and welding processes.

[0039] As a preferred embodiment, the detection unit 3 further includes a second detection frame 31, a first hydraulic cylinder body 32, an adapter 33, a second camera 34, and a cover plate 35. One end of the second detection frame 31 is fixedly mounted on the rear side wall of the right end of one of the conveyor belt assemblies 23, and the other end of the second detection frame 31 is located above the middle of a pair of conveyor belt assemblies 23. One end of the first hydraulic cylinder body 32 is fixedly mounted on the other end of the second detection frame 31, and the first cylinder is located above the conveyor belt assemblies 23. The adapter 33 is fixedly mounted on the telescopic end of the first hydraulic cylinder body 32. The second camera 34 is fixedly mounted on the lower wall of one end of the adapter 33. The cover plate 35 is detachably mounted on the lower wall of the adapter 33, and the cover plate 35 is movably fitted onto the second camera 34. The cover plate 35 is a plate of different sizes, and each of them has a hole for fitting the second camera 34.

[0040] More specifically, the detection unit 3 works in conjunction with the overall equipment process, and the specific working process is as follows: The distribution box with the back plate welded is in an inverted state and is conveyed to the right by the conveyor belt assembly 23. After being flipped 180 degrees forward by the two sets of flipping units 26 at the right end of the equipment, the box opening faces upward and is accurately conveyed to the work position directly below the detection unit 3. The conveyor belt assembly 23 stops running, so that the box opening is coaxially aligned with the telescopic axis of the first hydraulic cylinder body 32. Then the first hydraulic cylinder body 32 starts, and its telescopic end drives the adapter 33, the second camera 34 and the cover plate 35 to descend vertically in sync. The cover plate 35 first fits and presses against the edge of the box opening, completely sealing the box opening and creating a closed dark environment inside the box without external light interference. At the same time, the second camera 34 passes through the cover plate 35. The hole smoothly extends into the enclosed space inside the box; the second camera 34 is activated to perform panoramic imaging of the frame splicing welds and back plate joint welds around the box. If there are defects such as incomplete welding, weld penetration, or cracks in the welds, external light will enter the box through the defect gaps, forming obvious bright feature areas in the image captured by the second camera 34. The equipment control system can accurately determine the location, size, and type of welding defects through image recognition algorithms. After the inspection of a single box is completed, the main body 32 of the first hydraulic cylinder drives the adapter 33, the second camera 34, and the cover plate 35 to reset and rise synchronously, detach from the box and return to the avoidance position. The conveyor belt assembly 23 restarts, conveying the box that has completed the inspection out of the box and simultaneously receiving the next box to be inspected, realizing the continuous automated operation of the inspection process.

[0041] As a preferred embodiment, the carrying unit 4 further includes two pairs of carrying frames 41, two pairs of brackets 42, and a pair of baffles 43; one end of each of the two pairs of carrying frames 41 is symmetrically arranged on the conveyor belt assembly 23 and located between the flipping units 26; both pairs of brackets 42 are L-shaped, one end of each pair of brackets 42 is symmetrically arranged on the other end of the carrying frame 41, and the brackets 42 are symmetrical to each other; and a pair of baffles 43 are symmetrically arranged on the right side wall of one pair of brackets 42.

[0042] More specifically, the load-bearing unit 4 works in conjunction with the equipment conveying structure 2 and the reversing structure 5, and the specific working process is as follows:

[0043] Specification adaptation and adjustment: When the equipment is used to process different specifications of distribution boxes, the distance between the two sets of conveyor belt assemblies 23 is adjusted by the first electric slide rail 21. The conveyor belt assembly 23 drives the bearing frame 41 and the bracket 42 to move synchronously, automatically adjusting the support distance between the two pairs of brackets 42 so that it accurately matches the width of the corresponding specification back plate. Without the need to disassemble and adjust the tooling separately, the equipment can quickly change the storage position of the back plate of different specifications.

[0044] Batch loading of back panels: Insert the batch of back panels to be assembled horizontally between two pairs of opposing brackets 42 from the left side of the equipment, so that the bottom edges of the back panels overlap on the horizontal sections of the brackets 42 on both sides. Push the back panels to the right until their right end face is completely in contact with the baffle 43, thus completing the batch stacking and storage of the back panels. After stacking, a working gap is naturally formed between the bottom of the back panels and the conveying plane of the conveyor belt assembly 23, allowing the suction cups 58 of the reversing structure 5 to move up and down.

[0045] For single-plate pickup: After the reversing structure 5 completes the welding of the side wall of the box frame, it moves to the underside of the bearing unit 4 via the second electric slide rail 51. The main body 56 of the second hydraulic cylinder drives the plate frame 57 and the suction cup 58 to rise vertically. The suction cup 58 passes through the above-mentioned working gap and is completely attached to the lower wall of the bottom back plate. The air pump 59 starts to generate negative pressure, so that the suction cup 58 is firmly attached to the bottom back plate. Then, the main body 56 of the second hydraulic cylinder drives the suction cup 58 and the attached single back plate to descend vertically. Using the bracket 42 to support and limit the upper back plate, the single back plate is smoothly separated and extracted from the stacked material, completing the automated pickup of the single back plate. With the movement of the reversing structure 5, the back plate and the box frame are accurately docked.

[0046] As a preferred embodiment, the reversing structure 5 further includes a second electric slide rail 51, a third housing 52, a third motor 53, a third electric slide rail 54, a center seat 55, a second hydraulic cylinder body 56, a plate frame 57, several suction cups 58, an air pump 59, and a pair of fixing components 50. The second electric slide rail 51 is fixedly mounted on the upper wall of the middle part of the base 1, and the second electric slide rail 51 is located between the flipping units 26. The third housing 52 is fixedly mounted on the second electric slide rail 51, and the third housing 52 can move left and right. The third motor 53 is fixedly mounted inside the third housing 52, and the drive end of the third motor 53 moves through the third housing 52. The middle part of the third electric slide rail 54 is fixedly mounted on the drive end of the third motor 53, and the third electric slide rail 54 is symmetrically provided with relatively movable third slide seats. The center seat 55... The second hydraulic cylinder body 56 is fixedly installed in the middle of the third electric slide rail 54 and is fixedly installed on the upper wall of the center seat 55. The second hydraulic cylinder body 56 corresponds to the third motor 53. The disc frame 57 is fixedly installed on the telescopic end of the second hydraulic cylinder body 56. The disc frame 57 can be located below or above the conveyor belt assembly 23 through the second hydraulic cylinder body 56. Several suction cups 58 are fixedly installed on the disc frame 57 and are connected in series through the disc frame 57. The air pump 59 is fixedly installed on the center seat 55 and the air extraction end of the air pump 59 is connected to the disc frame 57 through a pipe. A pair of fixing components 50 are respectively installed on the third slide of the third electric slide rail 54 and are symmetrical to each other. The fixing components 50 can pass through the conveyor belt assembly 23 and can move to the right through the second electric slide rail 51 to be opposite to the bearing unit 4.

[0047] More specifically, the reversing structure 5 works in close coordination with the equipment's conveying structure 2, load-bearing unit 4, and welding unit 6, and has two operating modes. The specific working process is as follows:

[0048] Box frame clamping welding and rotation reversing mode: After the box frame has completed the orientation correction, it is transported by the conveyor belt assembly 23 to the work position directly above the reversing structure 5, and the conveyor belt assembly 23 stops running; the third electric slide rail 54 starts, driving the two fixed components 50 to move towards each other and adjust to the clamping distance matching the width of the box frame; then the fixed components 50 start, and their clamping ends pass vertically upward through the gap between the two sets of conveyor belt assemblies 23, forming a stable clamping on the left and right sides of the box frame, and lifting the box frame away from the conveying plane of the conveyor belt assembly 23, so that the box frame and the welding unit 6 form a suitable welding height.

[0049] Welding unit 6 is activated to weld the joints of the opposite side walls of the box frame. After a single weld is completed, the third motor 53 is activated to drive the third electric slide rail 54, the fixing component 50, and the box frame to rotate 90 degrees precisely, switching the welding side wall of the box frame and cooperating with welding unit 6 to complete the welding of the next weld. This cycle is repeated, and through four precise rotations, the full circumference automated welding of the four side wall joints of the box frame is completed.

[0050] Automated backplate picking and docking assembly mode: After the side wall of the box frame is welded, the second electric slide rail 51 is activated, driving the third chassis 52, the fixing component 50 and the clamped box frame to move to the right as a whole until the box frame is precisely moved to the top of the bearing unit 4, forming a coaxial and directly opposite position with the backplates stacked in the bearing unit 4; then the second hydraulic cylinder body 56 is activated, and its telescopic end drives the plate frame 57 and the suction cup 58 to rise vertically. The suction cup 58 passes through the gap between the conveyor belt components 23 and the inner cavity of the box frame until it is completely attached to the lower wall of the bottom backplate in the bearing unit 4.

[0051] At this time, the air pump 59 starts, and by pumping air, a stable negative pressure is formed between the suction cup 58 and the back plate, firmly adsorbing the bottom back plate onto the suction cup 58; then the second hydraulic cylinder body 56 drives the suction cup 58 and the adsorbed single back plate to descend vertically, and the bracket 42 of the bearing unit 4 supports and limits the upper back plate, realizing the smooth separation of the single back plate from the stacked material; the second electric slide rail 51 synchronously drives the whole to reset to the left to the welding station, and the second hydraulic cylinder body 56 drives the back plate to rise until it is completely in contact with the back plate mounting surface of the box frame, completing the precise docking and fastening of the back plate and the box frame; then, through the rotation and reversal of the third motor 53, the welding unit 6 completes the full circumference welding of the four joint seams between the back plate and the box frame.

[0052] As a preferred embodiment, the fixing component 50 further includes a fixing frame 501, a pair of third hydraulic cylinder bodies 502, a fourth electric slide rail 503, and a pair of clamping arms 504. One end of the fixing frame 501 is fixedly mounted on the third slide block of the third electric slide rail 54. The pair of third hydraulic cylinder bodies 502 are symmetrically mounted on the other end of the fixing frame 501. The fourth electric slide rail 503 is fixedly mounted on the telescopic end of the third hydraulic cylinder body 502, and the fourth electric slide rail 503 is parallel to the conveyor belt assembly 23. The fourth electric slide rail 503 is symmetrically mounted with relatively movable fourth slide blocks. The pair of clamping arms 504 are symmetrically mounted on the fourth slide blocks of the fourth electric slide rail 503, and both clamping arms 504 are L-shaped.

[0053] More specifically, this fixing component 50 works in close coordination with other components of the reversing structure 5, the welding unit 6, and the conveying structure 2 throughout the entire process. The specific working process is as follows:

[0054] Specification adaptation pre-adjustment: For distribution box frames of different widths, the third electric slide rail 54 drives the two fixing components 50 to move synchronously towards / away from each other, completing the overall spacing pre-adjustment of the two sets of fixing components 50; then the fourth electric slide rail 503 drives a pair of clamping arms 504 to move synchronously, adjusting the clamping distance of the two clamping arms 504 so that it accurately matches the width of the box frame to be processed, and can complete the rapid changeover of multiple specifications of products without changing the clamping fixture.

[0055] Clamping, lifting, and positioning: After the orientation of the box frame is completed, it is conveyed by the conveyor belt assembly 23 to the work position directly above the reversing structure 5, and the conveyor belt assembly 23 stops running; the third hydraulic cylinder body 502 starts, and its telescopic end drives the fourth electric slide rail 503 and the clamping arm 504 to rise vertically in sync, so that the clamping arm 504 passes through the gap between the two sets of conveyor belt assemblies 23 upwards until the horizontal section of the clamping arm 504 is higher than the bottom edge of the box frame; then the fourth electric slide rail 503 starts, driving a pair of clamping arms 504 to move towards each other, so that the vertical section of the clamping arm 504 fits tightly against the left and right side walls of the box frame, forming a stable clamping; the third hydraulic cylinder body 502 starts again, driving the clamped box frame to lift as a whole, so that the box frame is completely separated from the conveying plane of the conveyor belt assembly 23 and adjusted to the welding processing height that matches the welding unit 6.

[0056] The welding process is coordinated: During the welding of the box frame side wall by welding unit 6, the box frame can be moved vertically by the extension and retraction of the third hydraulic cylinder body 502, and the welding gun body 64 can achieve continuous welding of the weld seam at the full height. After the welding of a single weld seam is completed, the fixing component 50 is driven by the third motor 53 to complete the precise rotation and reversal, and simultaneously drive the box frame to switch to welding the side wall. During the process, the box is always stably clamped, without loosening or deviation.

[0057] Backplate docking process coordination: After the side wall of the enclosure frame is welded, the fixing component 50 moves synchronously to the right with the drive of the second electric slide rail 51, driving the clamped enclosure frame to move precisely above the bearing unit 4, forming a coaxial and directly opposite position with the stacked backplates; throughout the entire process of backplate picking, transfer, and fastening docking, the fixing component 50 always maintains rigid clamping and positioning of the enclosure frame, ensuring that the mounting surface of the backplate and the enclosure frame are precisely fitted without any misalignment, thus ensuring the fit of the subsequent backplate welding.

[0058] Finished product release and reset: After the back plate welding is completed, the main body 502 of the third hydraulic cylinder drives the box frame to descend and reset to the conveyor belt assembly 23. The fourth electric slide rail 503 drives the clamping arm 504 to move in opposite directions to release the box. The main body 502 of the third hydraulic cylinder drives the clamping arm 504 to descend and reset to below the conveyor belt assembly 23, completing a single processing cycle and waiting for the next box frame clamping processing.

[0059] As a preferred embodiment, the welding unit 6 further includes a pair of rail frames 61, an electric cross-shaped slide rail 62, a gun holder 63, and a welding gun body 64; one end of the pair of rail frames 61 is symmetrically arranged on the upper front wall of the base 1, and the rail frames 61 are opposite to the reversing structure 5; the electric cross-shaped slide rail 62 is fixedly arranged between the rail frames 61; one end of the gun holder 63 is fixedly arranged on the electric cross-shaped slide rail 62, and the gun holder 63 can move left and right and back and forth through the electric cross-shaped slide rail 62; the welding gun body 64 is detachably mounted on the other end of the gun holder 63, and the welding gun body 64 is opposite to the conveyor belt assembly 23.

[0060] More specifically, welding unit 6 works in close coordination with reversing structure 5 and fixing component 50 throughout the entire process, adapting to the two core processes of enclosure frame welding and back panel assembly welding. The specific working process is as follows:

[0061] Pre-adjustment of position before welding: For distribution box enclosures of different specifications, the gun holder 63 and the welding gun body 64 are first driven by the electric cross-shaped slide rail 62 to complete the initial position adjustment, so that the welding end of the welding gun body 64 and the welding seam of the enclosure to be welded by the reversing structure 5 form a precise welding distance and angle match; at the same time, according to the material of the enclosure and the welding process requirements, the appropriate welding gun body 64 is replaced to complete the process preparation before welding.

[0062] Box frame sidewall welding: After the fixing component 50 clamps the box frame and lifts it to the welding station, the electric cross-shaped slide rail 62 is activated, driving the welding gun body 64 to move to the starting position of the sidewall splice seam directly opposite the box frame, and the welding gun body 64 starts to perform welding; during the welding process, the third hydraulic cylinder body 502 of the fixing component 50 drives the box frame to complete the vertical lifting and lowering displacement, and cooperates with the welding gun body 64 to achieve full-height continuous welding of a single weld seam; after the welding of a single weld seam is completed, the third motor 53 drives the box frame to rotate precisely 90 degrees to switch the welding sidewall, and the electric cross-shaped slide rail 62 synchronously adjusts the position of the welding gun body 64, repeating the above welding process. Through four rotations and reversals, the full-circumference automated welding of the four sidewall splice seams of the box frame is completed.

[0063] Welding of the joint between the back panel and the frame: After the back panel and the box frame are precisely aligned and fastened, the electric cross-shaped slide rail 62 drives the welding gun body 64 to move to the joint position between the back panel and the box frame. In conjunction with the third motor 53 driving the rotation and reversal of the box, and the lifting and lowering adjustment of the third hydraulic cylinder body 502, the full-circumference automated welding of the four joints between the back panel and the box frame is completed. During the welding process, the front-back and left-right positions of the welding gun body 64 can be finely adjusted in real time through the electric cross-shaped slide rail 62 to adapt to the changes in the direction of the weld and ensure the weld fit. After all the welds of the box are completed, the electric cross-shaped slide rail 62 drives the gun holder 63 and the welding gun body 64 to return to the initial clearance position to avoid interference with the subsequent transport and flow of the box, and wait for the processing cycle of the next box to be welded.

[0064] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0065] The equipment is placed stably on the base 1. During processing and use, the conveyor belt assembly 23 in the conveying structure 2 moves synchronously and parallelly, carrying the assembled box frame to move (at this time, the box has front, back, left and right side walls, no back panel and box door). According to the processing of box of different sizes, the first electric slide rail 21 can be activated to drive the conveyor belt assembly 23 on the conveyor frame 22 to adjust the spacing, and at the same time drive the corresponding bearing unit 4 to adjust the spacing.

[0066] When the box frame moves from left to right, the first camera 25 on the first detection frame 24 determines whether the upper wall edge of the box frame is aligned with the back panel. If it is the same side, the two flipping units 26 located near the left end are activated. The second motor 264 inside the second housing 263 is activated, and the second motor 264 drives the second pallet 266 to flip to the right on the first pallet 265, so that the first pallet 265 and the second pallet 266 are parallel, and the box frame moves to the right through the conveyor belt assembly 23.

[0067] When the detection indicates that it is not aligned with the back panel, the box frame is blocked by the L-shaped vertical alignment of the second support plate 266 and the first support plate 265. Then, the first motor 262 inside the first chassis 261 is started, which drives the first support plate 265 and the second support plate 266 to rotate 90 degrees on the flipping frame 260 through the shaft column 7. The box frame is rotated 90 degrees after passing through one flipping unit 26. Before welding, it is rotated 180 degrees by passing through two flipping units 26.

[0068] The telescopic plate 268 in the flipping unit 26 can telescopically move within the first support plate 265 and the second support plate 266, and is fixed by fastening bolts 267 to achieve the length of support and limit, which can fit the processing of box bodies of different sizes. At the same time, when the first support plate 265 and the second support plate 266 are flipped, in order to prevent the subsequent box body frame from moving to the flipping unit 26 and affecting the reset of the flipping unit 26, a roller frame 269 and a guide roller 270 are set below the first support plate 265. After the first support plate 265 is flipped 90 degrees, the roller frame 269 drives the guide roller 270 to flip, causing the guide roller 270 to block the subsequent box body to the left.

[0069] Then the box frame moves to the reversing structure 5 and stops driving the conveyor belt assembly 23; then the third hydraulic cylinder body 502 on the fixed frame 501 in the fixed assembly 50 can be activated, driving the fourth electric slide rail 503 to rise, causing the clamping arm 504 to pass through the conveyor belt assembly 23 and rise, and the fourth electric slide rail 503 is activated to cause the clamping arm 504 to move relative to clamp the left and right side walls of the box frame. After clamping, the third hydraulic cylinder body 502 can be activated to drive the box to rise to a certain height, so that the box frame can be separated from the conveyor belt assembly 23.

[0070] At this time, welding unit 6 can be started. The electric cross-shaped slide rail 62 on the rail frame 61 drives the welding gun body 64 on the gun holder 63 to move left and right and back and forth to weld the connection of the side wall of the box frame. Since the box frame has no upper and lower side walls at this time, the welding gun only needs to be driven to rotate by the third motor 53 in the third housing 52 as the box rotates. When adjusting different side walls, it can be moved left and right to adjust the position. The welding at this time is vertical welding, which can be started with the third hydraulic cylinder body 502.

[0071] After the fixed box frame is welded to the side wall, it can also be moved to the right by the second electric slide rail 51, so that the box is opposite to the stacked back plates in the bearing unit 4; that is, the bracket 42 is connected to the conveyor belt assembly 23 through the bearing frame 41, and the spacing adjustment of the conveyor belt assembly 23 synchronously drives the spacing of the bracket 42, thereby changing the size of the back plates used for different boxes; the back plates are supported by L-shaped trays, that is, the stacked back plates are inserted into the brackets 42 to the right, and the placement is achieved by the baffles set on the side wall to block and limit the movement;

[0072] After the housing and back plate are aligned, the second hydraulic cylinder body 56 can be activated to drive the plate frame 57 and suction cup 58 to rise. At this time, the suction cup 58 passes through the housing frame from below the conveyor belt assembly 23 and uses the air pump 59 to generate suction force, causing the suction cup 58 to adsorb the back plate at the bottom. Then it moves to the left to reset, pulls out the back plate for unloading, and the second hydraulic cylinder body 56 retracts to reset, causing the back plate to be fastened to the housing frame for positioning. At this time, through the cooperation of the welding unit 6 and the reversing unit, the housing frame and back plate are rotated to perform welding of the four side walls.

[0073] After the back panel is welded, the box is upside down on the conveyor belt assembly 23. Therefore, the welded box continues to be conveyed to the right and is flipped 180 degrees again by the two flipping units 26 at the right end to achieve upright placement.

[0074] After being placed upright, the box is moved to the detection unit 3. The first hydraulic cylinder body 32 on the second detection frame 31 drives the prefabricated cover plate 35 and the camera on the adapter 33 to descend, causing the cover plate 35 to be fastened on the top of the box. The second camera 34 is located in the box. The inside of the box is blocked by the cover plate 35, forming a dark environment. The second camera 34 can then be used to image the inside and detect whether the weld can be observed by an external light source to determine welding defects.
