[0052] Step S60, controlling the pressing plate structure to simultaneously press the third plate, the fourth plate and the fifth plate;

[0053] Step S70, controlling the splicing correction structure to simultaneously clamp the upper end of the third plate, the upper end of the first plate, and the upper end of the second plate, so that the upper end of the third plate is perpendicular to the upper end of the first plate and the upper end of the second plate, respectively, wherein the upper end of the first plate is close to the third plate, and the upper end of the second plate is close to the third plate;

[0054] Step S80, controlling the welding device to weld the first splicing portion, the second splicing portion, the third splicing portion, the fourth splicing portion, the fifth splicing portion and the sixth splicing portion respectively.

[0055] Specifically, refer to Figure 3 The support frame 100 of the embodiment of the present application is formed with multiple side surfaces by multiple support rods, and different side surfaces can provide a support basis for the splicing and welding process of plates of different sizes.

[0056] Specifically, in some embodiments, each side of the support frame 100 of this embodiment is provided with a solenoid valve, Figure 3 The first solenoid valve 114 is disposed on the first side of the support frame 100, and the fourth solenoid valve 144 is disposed on the fourth side of the support frame 100. The solenoid valves serve as a trigger structure basis for driving the positioning structure disposed on the same side of the support.

[0057] In addition, the embodiment of the present application does not limit the specific number of solenoid valves arranged on each side of the support frame 100, which can be one or more. Since the solenoid valves are communicatively connected to the control device, when the number of solenoid valves on a certain side of the support frame 100 is multiple, the solenoid valves can be evenly distributed on the corresponding side of the support frame 100 (the specific installation position of the solenoid valves is not restricted here) to more accurately detect whether the placed plates are in place, and the control device needs to receive the trigger signals of all the solenoid valves on the same side before driving the corresponding positioning structure on the same side.

[0058] Exemplarily, for the solenoid valves and positioning structures arranged on the same side, since the control device is respectively connected to the solenoid valves and positioning structures located on the same side of the support frame 100, when the control device receives the first trigger signal from the first solenoid valve 114, it indicates that the first plate 113 is currently placed in place on the first side of the support frame 100, and sends a driving instruction to the driving device corresponding to the first positioning structure to drive the first positioning structure to fix the first plate 113 on the first side of the support frame 100.

[0059] Specifically, the pressure plate structure of this embodiment is used to press the surface of the plate after all the plates constituting the air chamber of the ring main unit are placed in place and fixed on the corresponding side of the support frame 100 respectively, so that each plate is more firmly positioned on the corresponding side of the support frame 100 before welding the joints between the plates.

[0060] Specifically, since each positioning structure is triggered and driven in sequence in the order of steps S10 to S50 and fixes the corresponding plates in place, the triggering condition for driving the pressure plate structure to press the third plate 132, the fourth plate 143 and the fifth plate 153 is that the first positioning structure completes the fixation of the fifth plate 153.

[0061] Specifically, the splicing correction structure of this embodiment is used to, after the pressing plate structure presses the surface of the plate, refer to Figure 2 , clamp the two upper ends of the third plate 132 away from the pressure plate structure, the upper end of the first plate 113 close to the third plate 132, and the upper end of the second plate close to the third plate 132, so that the upper end of the third plate 132 is perpendicular to the upper end of the first plate 113 and the upper end of the second plate, respectively, and the edges are aligned with each other, avoiding subsequent welding misalignment and providing protection for the welding quality of the ring network cabinet air chamber.

[0062] In addition, it should be noted that the present embodiment does not limit the specific method of placing the first plate 113, the second plate 132, the fourth plate 143 and the fifth plate 153 on the corresponding side of the support frame 100 respectively. The present embodiment is based on a loading robot arm with a camera. The image of the support frame 100 and the plate image are obtained by the camera to plan the movement path of the loading robot arm, and the loading robot arm is controlled to grab each plate and place it on the corresponding side of the support frame 100 in turn based on the planned movement path, in preparation for plate splicing and welding; or a corresponding loading robot arm is provided on each side of the support frame 100, and each loading robot arm places the plate one-to-one on the corresponding position of the support frame 100.

[0063] It should be noted that the present embodiment does not involve any improvement to the welding device. Those skilled in the art may select the specific structure of the welding device according to actual needs. The present embodiment may use a movable welding device with a camera to obtain images corresponding to the first splicing part, the second splicing part, the third splicing part, the fourth splicing part, the fifth splicing part and the sixth splicing part through the camera to determine the position of the splicing parts, plan the moving path of the welding device based on the positions of each splicing cloth, and control the welding device to weld each splicing part in sequence based on the planned moving path.

[0064] In addition, after determining that the plate welding of the ring network cabinet air chamber is completed, a ring network cabinet air chamber shell is obtained. The method provided in this embodiment also includes: sequentially controlling the driving device corresponding to the pressure plate structure, the fifth solenoid valve, the fourth solenoid valve 144, the third solenoid valve, the second solenoid valve, the first solenoid valve 114 and the driving device corresponding to the splicing correction structure to be powered off. Since the power-on of each solenoid valve is a trigger condition for driving the corresponding positioning structure to start, therefore, powering off the solenoid valve can make the driving device corresponding to the corresponding positioning structure and the splicing correction structure and the pressure plate structure return to the standby position, so that each plate is separated from the corresponding positioning structure, as well as the positioning function of the splicing correction structure and the pressure plate structure. After that, the welded ring network cabinet air chamber shell is removed by controlling the unloading robot arm to complete the unloading; when there is a new ring network cabinet air chamber plate welding demand, the plate welding method of the ring network cabinet air chamber of the above embodiment is re-executed to realize the loading, splicing, welding and unloading of the plate to complete the production of the next ring network cabinet air chamber shell.

Compared with manual operation, the plate welding accuracy and welding efficiency of the ring main unit air chamber can be effectively improved.

[0066] Specifically, this embodiment does not limit the specific structure of the positioning structure arranged on different sides of the support frame 100. For example, referring to Figure 3 The first positioning structure on the first side of the support frame 100 is a first core-pulling shaft 112 and a first suction cup 111, and the fourth positioning structure on the fourth side of the support frame 100 is composed of a column 141 and a rotating block 142 movably connected to the column 141, which can realize the positioning of the plate placed on the corresponding side of the support frame 100.

[0067] In addition, in some embodiments, the first plate is provided with a plurality of first through holes, the first positioning structure includes a plurality of first suction cups and a plurality of first mandrel-pulling shafts, the size of each first through hole matches the size of the first mandrel-pulling shaft, and the number of the first through holes is the same as the number of the first mandrel-pulling shafts. Figure 1 Step S10 includes but is not limited to the following steps:

[0068] Step S11, controlling each first suction cup to adsorb the first plate;

[0069] Step S12, controlling each first core-pulling shaft to extend from the first side by a first preset distance and pass through the corresponding first through hole.

[0070] Understandably, reference Figure 2 and Figure 3 In the case where the first plate 113 includes a plurality of first through holes, and the first positioning structure includes a plurality of first suction cups 111 and a plurality of first core-pulling shafts 112, each of the first suction cups 111 is controlled to adsorb the first plate 113 to provide a lateral force for the first plate 113, and each of the first core-pulling shafts 112 is controlled to extend a first preset distance from the first side and pass through the corresponding first through holes to provide gravity support for the first plate 113, thereby enabling the first plate 113 to be stably fixed on the first side of the support frame 100.

[0071] It should be noted that the embodiment of the present application does not limit the distribution and specific number of the first suction cup 111 and the first core-pulling shaft 112 on the first side of the support frame 100. Figure 3As shown, five first suction cups 111 are evenly distributed along the first side edge of the support frame 100, and the setting position of the first core-pulling shaft 112 is determined by the position of the first through hole of the first plate 113 corresponding to the first side of the support frame 100. For example, since two first through holes are set at the front end edge of the first plate 113, the first core-pulling shaft 112 matching the aperture of the first through hole is set as shown in FIG. Figure 3 The corresponding positions shown.

[0072] In addition, in some embodiments, the second plate is provided with a plurality of second through holes, the second positioning structure includes a plurality of second suction cups and a plurality of second mandrel-pulling shafts, the size of each second through hole matches the size of the second mandrel-pulling shaft, and the number of the second through holes is the same as the number of the second mandrel-pulling shafts. Figure 1 Step S20 includes but is not limited to the following steps:

[0073] Step S21, controlling each second suction cup to adsorb the second plate;

[0074] Step S22, controlling each second core-pulling shaft to extend from the second side by a second preset distance and pass through the corresponding second through hole.

[0075] Specifically, the first plate and the second plate of this embodiment have the same size, and the second positioning structure has the same specific structure as the first positioning structure. The difference is that they are arranged on different corresponding sides of the support frame. The technical principle of controlling the second positioning structure to fix the second plate on the second side of the support frame can refer to the specific embodiments of steps S11 to S12, and will not be elaborated here.

[0076] In addition, in some embodiments, the third plate is provided with a plurality of third through holes, the third positioning structure includes a plurality of third mandrel-pulling shafts, the number of the third through holes is the same as the number of the third mandrel-pulling shafts, and the size of each third through hole matches the size of the third mandrel-pulling shaft. Figure 1 Step S30 includes but is not limited to the following steps:

[0077] Step S31, controlling each third core-pulling shaft to extend from the third side by a third preset distance and pass through the corresponding third through hole.

[0078] Understandably, reference Figure 2 In this embodiment, the third plate 132 is placed on the top side (i.e., the third side) of the support frame 100. After the third plate 132 is placed on the third side of the support frame 100, the bottom of the third plate 132 is supported by a support rod. By controlling the third core-pulling shaft 131 to pass through the through hole of the third plate 132, the third plate 132 can be positioned on the third side of the support frame 100.

[0079] It should be noted that the embodiments of the present application do not limit the specific first preset length, second preset length and third preset length, and those skilled in the art may adjust them according to actual conditions.

[0080] In addition, in some embodiments, the fourth plate includes a plurality of fourth through holes, the number of the fourth positioning structures is multiple, the number of the fourth through holes is the same as the number of the fourth positioning structures, each fourth positioning structure includes a column and a rotating block, the rotating block is rotatably connected to the column through a rotating shaft, and the rotating shaft is communicatively connected to the control device through a corresponding driving device. Figure 1 Step S40 includes but is not limited to the following steps:

[0081] Step S41 , driving the rotating shaft to rotate by a preset angle to drive each rotating block to rotate relative to each corresponding column, so that the rotating block presses the corresponding edge of the fourth through hole.

[0082] It can be understood that the fourth plate 143 of this embodiment is in the shape of an L-shaped plate. Figure 2 and Figure 3 , the fourth plate 143 is placed on the other side of the top of the support frame 100 (i.e., the fourth side). After the fourth plate 143 is placed on the fourth side of the support frame 100, since the bottom of the fourth plate 143 is supported by a support rod, the rotating shaft is controlled to rotate by a preset angle so that each rotating block 142 rotates relative to each corresponding column 141, so that the rotating block 142 presses the corresponding fourth through hole edge, thereby fixing the fourth plate 143 on the fourth side of the support frame 100. When welding is completed, the rotating shaft is controlled to rotate in the opposite direction by a preset angle so that the rotating block 142 and the corresponding fourth through hole edge are separated from each other, so that the fourth positioning structure releases the positioning effect on the fourth plate 143, and prepares for unloading.

[0083] It should be noted that the embodiments of the present application do not limit the specific rotation angle, and those skilled in the art may adjust it according to actual conditions.

[0084] In addition, in some embodiments, the fifth plate is provided with a fifth through hole, the fifth positioning structure includes a plurality of fifth suction cups and a stopper, and each of the fifth suction cups and the stopper is communicatively connected to the control device through a corresponding driving device. Figure 1 Step S50 includes but is not limited to the following steps:

[0085] Step S51, controlling each fifth suction cup to adsorb the fifth plate onto the fifth side of the support frame;

[0086] Step S52, controlling the limiting member to clamp the edge of the fifth through hole.

[0087] It should be noted that this embodiment does not limit the specific structure of the limiter. Figure 2As shown, the size of the limiting member 152 is smaller than the fifth through hole. After the fifth suction cup 151 adsorbs the fifth plate 153, the limiting member 152 is controlled to clamp the edge of the fifth through hole. Under the action of the fifth suction cup 151 and the limiting member 152, the fifth plate 153 can be stably fixed on the fifth side of the support frame 100.

[0088] In addition, in some embodiments, the third plate, the fourth plate and the fifth plate form a stepped structure, and the pressure plate structure includes a stepped pressure rod and a push plate. Figure 1 Step S60 includes but is not limited to the following steps:

[0089] Step S61, controlling the push plate to press toward the fifth plate through the corresponding driving device, so that the push plate abuts against the fifth plate;

[0090] Step S62: Control the stepped pressure rod to press the third plate, the fourth plate and the fifth plate simultaneously through the corresponding driving device, so that the stepped pressure rod abuts against the third plate, the fourth plate and the fifth plate simultaneously.

[0091] Specifically, refer to Figure 2 and Figure 3 The pressing plate structure of this embodiment includes a stepped pressing rod 171 and a push plate 172. The push plate 172 is slidably connected to a guide rail 173 connected to the bottom cross bar of the support frame 100. After determining that the fifth plate 153 is placed in place, a pressing plate instruction is sent to a driving device corresponding to the push plate 172 to control the push plate 172 to press the fifth plate 153 along the guide rail 173, so that the push plate 172 and the fifth plate 153 are abutted, thereby making the splicing between the fifth plate 153 and the third plate 132, the first plate 113 and the second plate tighter; then the stepped pressing rod 171 is controlled to press Towards the surface of the third plate 132, the fourth plate 143 and the fifth plate 153, since the stepped pressure rod 171 is composed of four sections of mutually perpendicular rod bodies, after the stepped pressure rod 171 is pressed against the surfaces of the third plate 132, the fourth plate 143 and the fifth plate 153 that are spliced ​​to each other, the different rod bodies of the stepped pressure rod 171 respectively abut against the surfaces of the third plate 132, the fourth plate 143 and the fifth plate 153, which can ensure that the splicing edges between the third plate 132, the fourth plate 143 and the fifth plate 153 are perpendicular to each other and at the same time play the role of overlapping.

[0092] It should be noted that the driving device of the push plate 172 of this embodiment can be as follows: Figure 2 and 3 The cylinder 174 is shown, but no further limitation is given here.

[0093] In addition, in some embodiments, the splicing correction structure includes a first gripping clamp and a second gripping clamp, and the upper end of the third plate includes a first end and a second end, the first end is close to the first plate, and the second end is close to the second plate. Figure 1 Step S70 includes but is not limited to the following steps:

[0094] Step S71, controlling the first gripper to simultaneously clamp the first end and the upper end of the first plate, so that the first end and the upper end of the first plate are perpendicular to each other, and the edge of the first end is flush with the edge of the upper end of the first plate;

[0095] Step S72, controlling the second gripper to simultaneously clamp the second end and the upper end of the second plate so that the second end and the upper end of the second plate are perpendicular to each other, and the edge of the second end is flush with the edge of the upper end of the second plate.

[0096] Specifically, since the welded product of this embodiment is the air chamber shell of the ring network cabinet, it is necessary to ensure that the joints between the plates constituting the air chamber shell of the ring network cabinet are aligned and the joint angle meets the requirement of 90 degrees. Figure 2 and Figure 3 After the pressing operation of the third plate 132, the fourth plate 143 and the fifth plate 153 is completed by the pressing plate structure, the splicing edges of the third plate 132, the fourth plate 143 and the fifth plate 153 are made perpendicular to each other, thereby ensuring the splicing effect of the end of the ring network cabinet air chamber shell close to the pressing plate structure. However, the third plate 132 after the pressing operation of the pressing plate structure may be misaligned with the first plate 113 and the second plate, resulting in the third plate 132 being not flush with the edge of the first plate 113 or the second plate at the end away from the pressing plate structure. In order to ensure the overall splicing effect, this embodiment clamps the upper end of the third plate 132, the upper end of the first plate 113 and the upper end of the second plate through a splicing correction structure including a first gripping clamp 161 and a second gripping clamp 162, so that the upper end of the third plate 132 is perpendicular to the upper end of the first plate 113 and the upper end of the second plate, respectively. Specifically, the first gripping clamp 161 is controlled to clamp the first end and the upper end of the first plate 113 at the same time, so that the first end is perpendicular to the upper end of the first plate 113, and the edge of the first end is flush with the edge of the upper end of the first plate 113; the second gripping clamp 162 is controlled to clamp the second end and the upper end of the second plate at the same time, so that the second end is perpendicular to the upper end of the second plate, and the edge of the second end is flush with the edge of the upper end of the second plate, thereby ensuring the overall splicing effect between the spliced ​​plates.
