Description

Technical Field

[0001] The invention relates to the field of welding equipment, and in particular to a cross plate welding equipment and an operating method thereof. Background Art

[0002] At present, a Chinese invention with the announcement number CN108817783B discloses a welding device for automatically welding pipes, the welding device includes: a welding robot; a first positioning part, the first positioning part is used to position one end of the pipe; a second positioning part, the second positioning part is used to position the other end of the pipe, and the second positioning part is movably arranged relative to the first positioning part; wherein a positioning space for positioning the pipe is formed between the first positioning part and the second positioning part, the first positioning part and the second positioning part are relatively close to position the pipe in the positioning space, and the welding robot is used to weld the positioned pipe. The welding device of this invention solves the problem that the welding equipment in the prior art cannot meet the welding requirements of pipes of different lengths; Although the existing welding equipment is equipped with a single clamping component that can fix products of different lengths, there are still other problems during use, such as poor welding effect. The cross plate is composed of a long plate and two short plates before welding. The two short plates are welded on both sides of the long plate to form a "cross shape". It is difficult to handle the short plates when the long plates are limited unilaterally. Therefore, personnel are often required to hold the short plates to align and push them toward the long plates, which is time-consuming and labor-intensive, and it is difficult to ensure the quality of the weld. In addition, it does not have dust collection and purification functions. A large amount of smoke will be generated during the welding process. The smoke will carry light-density particles and harmful substances. If it is not collected and treated in time, it will quickly melt into the air and be inhaled by the human body, which will not only pose a great threat to human health, but also damage the surrounding environment and cause pollution, increasing the cleaning burden of personnel. In order to solve the above-mentioned problems, we propose a cross plate welding equipment and its operation method. Summary of the invention

[0012] The present invention is further configured as follows: the top and the bottom of the activated carbon filter are both clamped with a clamping seat, and the other sides of the two clamping seats are bolted to the inner frame and the outer box frame respectively.

[0013] By adopting the above technical solution, the activated carbon filter can be limited by the setting of the holder to prevent the activated carbon filter from shifting and tilting due to the influence of wind after being placed in.

[0022] A cross plate welding equipment operation method comprises the following steps: S1: First, grab the base plate and pull the fixed seat outward. When the fixed seat is pulled outward to the bottom, place the two ends of the long board into the two first limit seats. After the long board is placed, pick up the two short boards and place them into the two second limit seats respectively. After the short boards are placed, hold the handle with your hand to drive the bidirectional screw to rotate. When the bidirectional screw rotates, it will drive the two threaded plates to move inward synchronously through the cooperation of the slide rail and the slider. When the threaded plates move inward, they will drive the second limit seats to move together. When the second limit seats move, they will push the short boards to make close contact with the long boards, and then push the base plate inward again to the bottom to make the first magnetic block and the second magnetic block adsorb; S2: Start the cylinder and the welding head at the same time. After the cylinder is started, it will drive the fixing frame to move downward. When the fixing frame moves downward, it will drive the two welding heads to move downward together. During the downward movement of the two welding heads in the started state, they will weld and fix the two contact surfaces of the short plate and the long plate at the back at the same time; S3: Since the whole needs to be welded on four sides, start the motor after double-sided welding. After starting, the motor will drive the first bevel gear to rotate. When the first bevel gear rotates, it will drive the rotating shaft to rotate through the cooperation of the second bevel gear. When the rotating shaft rotates, it will drive the fixed seat to rotate together through the cooperation of the bearing and the fixed frame. After the fixed seat rotates to an angle of 180 degrees, the two unwelded surfaces will be swapped with the welded surfaces. Then continue to start the cylinder to drive the welding head to weld and fix the remaining two welding surfaces; S4: The product starts the axial flow fan during the welding process. After starting, the axial flow fan will discharge the air in the channel between the outer box frame and the inner frame from the exhaust port. The air will be in a negative pressure state in the channel when it is discharged. In the negative pressure flat pressure state, the smoke generated in the welding process will be sucked into the channel through the suction hole. The dust-containing gas will pass through the activated carbon filter when flowing in the channel. The activated carbon filter will adsorb and intercept impurities and harmful components in the gas. The impurities after interception will fall down into the collection box. The collection box can be taken out of the outer box frame for cleaning by grabbing the pull plate and pulling it outward.

[0023] In summary, the present invention has the following beneficial effects: 1. The present invention places the two ends of the long plate into the two first limit seats first, and then respectively places the two short plates into the two second limit seats after the long plate is placed. After the short plates are placed, the handle is held by hand to drive the bidirectional screw to rotate. When the bidirectional screw rotates, the two threaded plates are driven to move inward synchronously through the cooperation of the slide rail and the slider. When the threaded plate moves inward, it drives the second limit seat and the short plate to move together. Then the base plate is pushed inward to the bottom and the cylinder is started. After the cylinder is started, the two welding heads are driven to move down to weld and fix the two contact surfaces at the same time. Finally, the motor is started to drive the fixed seat to rotate. After the fixed seat rotates, the welded surface and the unwelded surface are adjusted. Finally, the cylinder is started again to make the welding head perform secondary welding, which can achieve good welding effect, accelerate the welding speed of the four sides of the product, reduce the burden of repeated taking and placing and position adjustment of personnel, and ensure the welding quality of the welding surface of the product, so as to achieve compact and seamless welding, and high practicality. 2. The present invention starts the axial flow fan, which will discharge the air in the channels between the outer box frame and the inner frame from the exhaust port. The air will be in a negative pressure state in the channel when it is discharged. The smoke generated in the welding process will be sucked into the channel through the suction hole in the negative pressure flat pressure state. The dust-containing gas will pass through the activated carbon filter when flowing in the channel. The activated carbon filter will adsorb and intercept impurities and harmful components in the gas. The impurities after interception will fall downward into the collection box. The collection box can be taken out of the outer box frame for cleaning by grabbing the pull plate and pulling it outward. It can have the dust collection and purification function, protect the health of the surrounding personnel, improve the surrounding working environment, and facilitate the personnel to clean up the impurities.

After the fixed seat (12) rotates to an angle of 180 degrees, the two unwelded surfaces are exchanged with the welded surfaces. Then, the cylinder (41) is started to drive the welding head (43) to weld and fix the remaining two welding surfaces; S4: During the welding process, the axial flow fan (6) is started. After being started, the axial flow fan (6) will discharge the air in the channel between the outer box frame (1) and the inner frame (2) from the exhaust port (7). When the air is discharged, the channel will be in a negative pressure state. In the negative pressure state, the smoke and dust generated during the welding process will be sucked into the channel through the suction hole (5). When the dust-containing gas flows in the channel, it will pass through the activated carbon filter (8). The activated carbon filter (8) will adsorb and intercept impurities and harmful components in the gas. The impurities that have been intercepted will fall downward into the collection box (9). The collection box (9) can be taken out of the outer box frame (1) for cleaning by grabbing the pull plate (21) and pulling it outward.
