[0010] The inner wall of the water storage tank is fixedly connected with a water mist mechanism, and the water mist mechanism includes an atomizer, and the atomizer is fixedly connected to the inner left side of the water storage tank.

The outer wall of the bearing is fixedly connected to the top of the water storage tank, and a sponge board is fixedly connected to the bottom of the rotating rod. The sponge board is plugged into the top of the water inlet bin, and a water spray pipe is fixedly connected to the bottom of the water bin, and the bottom of the water spray pipe is located at the top position of the water inlet bin.

[0013] A welding method for a conveyor frame sheet metal welding device, comprising the following steps: S1. Place the sheet metal parts to be welded on a workbench, on which fixed parts are arranged, and then fix the sheet metal parts on the workbench. The welding machine is powered on to start welding the sheet metal parts on the workbench, and a camera device can be connected to the network to observe the sheet metal parts on the workbench. S2. After a stage of welding, the water pump is powered on and started, the water inlet of the water pump is connected to a water source, and then the water pump draws water from the water source and transports it to the water pipe through a zigzag pipe, and then the water flow is blown out from a high-pressure water nozzle. The arrangement of multiple high-pressure water nozzles corresponds to multiple slag-discharging spikes, respectively. Under the impact of the water flow of the high-pressure water nozzle, the slag-discharging spikes are moved in the placement holes, and the slag-discharging spikes move toward the left side and hit the sheet metal on the workbench. When the slag-discharging spikes hit the welding slag, the water flow is first sprayed from the water outlet of the slag-discharging spikes onto the welding slag of the sheet metal to cool the welding slag; S3. When the slag spurs hit the welding slag, the welding slag is knocked down. The water sprayed from the subsequent water outlet flows onto the welding slag, which also washes the welding slag away. Moreover, the water flow is sprayed toward the left side, so the water flow will guide the welding slag to fall into the water storage tank. S4, the electric slider is powered on and starts to move back and forth on the slide rail, so the position of the high-pressure water nozzle will be changed. When the water flow from the high-pressure water nozzle hits the slag thorn, the impact of the water flow causes the slag thorn to move to the left, and then stops when the slag thorn contacts the sheet metal. When the electric slider changes its position later, the position of the slag thorn is changed, so that multiple slag thorns are discontinuously changed to clean the welding slag on the sheet metal. The second motor is powered on and starts to drive the workbench to rotate, thereby changing the direction of the sheet metal. After the high-pressure water nozzle passes the position of the slag thorn, the elasticity of the spring will pull the slag thorn to reset; S5. The water sprayed from the high-pressure water nozzle will also fall into the water tank, and then be discharged into the water inlet tank through the water spray pipe. The atomizer is powered on and starts to suck the water in the water inlet tank through the first connecting pipe and then squeeze out the water mist. The first motor is powered on and starts to drive the fan blades to rotate and guide the water mist toward the workbench. The water mist falls on the welding slag, quickly cools the welding slag, and the water mist also reduces the smoke generated by welding in the air. S6. The second gear is also driven to rotate by the second motor. The meshing of the second gear and the first gear drives the rotating rod and the sponge plate to rotate. The sponge plate filters the water inlet bin to prevent the welding slag in the water storage tank from falling into the water inlet bin. The rotation of the sponge plate will throw off the welding slag filtered on the sponge plate.

[0014] The present invention provides a conveyor frame sheet metal welding device and a welding method, which have the following beneficial effects: 1. The conveyor frame sheet metal welding device and welding method utilize the impact of water flow to make the slag thorn move in the placement hole. The slag thorn moves toward the left and hits the sheet metal on the workbench. When the slag thorn hits the welding slag, the water flow is first sprayed from the water outlet of the slag thorn onto the welding slag of the sheet metal to cool the welding slag. The flushing of the water flow is combined with an atomizer to cool the welding slag, which is convenient for the subsequent cleaning efficiency of the welding slag.

[0015] 2. The conveyor frame sheet metal welding device and welding method, through the activity of the slag collision spikes to hit the welding slag, the welding slag is knocked down, and the welding slag is treated. The water sprayed from the water outlet flows onto the welding slag, so that the welding slag is washed away. The washing of the water flow has the effect of the welding slag falling, and the treatment efficiency of the welding slag is improved. The water flow is sprayed toward the left side, so the water flow will guide the welding slag to fall into the water storage tank, and the water flow is used to guide the welding slag, thereby avoiding the accumulation of welding slag.

[0016] 3. The conveyor frame sheet metal welding device and welding method use the impact of water flow to move the slag spikes toward the left side, and the slag spikes will stop when they touch the sheet metal. When the electric slider changes its position later, the position of the slag spikes will be changed, so that multiple slag spikes will be discontinuously changed to clean the welding slag on the sheet metal. The impact of water flow is used to make the slag spikes fit the sheet metal, and the setting of multiple slag spikes can also effectively fit sheet metals with different deformations, ensuring the treatment of welding slag.

[0017] 4. The conveyor frame sheet metal welding device and welding method squeeze out water mist through an atomizer, and the first motor guides the water mist toward the workbench. The water mist falls on the welding slag, quickly cools the welding slag, accelerates the cooling of the welding slag, and improves the subsequent processing efficiency of the welding slag. The water mist also reduces the smoke generated by welding in the air, which is convenient for observation of welding.

[0018] 5. The conveyor frame sheet metal welding device and welding method filters the water inlet bin through a sponge plate to prevent welding slag in the water storage tank from falling into the water inlet bin. The rotation of the sponge plate will throw off the welding slag filtered on the sponge plate, ensuring the continuous spraying of water mist. BRIEF DESCRIPTION OF THE DRAWINGS

When the high-pressure water nozzle (58) sprays water to impact the slag thorn (53), the impact of the water causes the slag thorn (53) to move to the left, and then the slag thorn (53) stops when it contacts the sheet metal. When the electric slider (15) changes its position, the position of the slag thorn (53) is changed, so that multiple slag thorns (53) are intermittently changed to clean the welding slag on the sheet metal. The second motor (13) is powered on and started to drive the workbench (1) to rotate, thereby changing the direction of the sheet metal. After the high-pressure water nozzle (58) passes the position of the slag thorn (53), the elasticity of the spring (54) pulls the slag thorn (53) to reset. s5. The water sprayed by the high-pressure water nozzle (58) also falls into the water tank (51), and then is discharged into the water inlet tank (63) through the water spray pipe (10). The atomizer (68) is powered on and started to suck the water in the water inlet tank (63) through the first connecting pipe (67) and then squeeze out the water mist. The first motor (8) is powered on and started to drive the fan blade (7) to rotate and guide the water mist toward the workbench (1). The water mist falls on the welding slag, quickly cooling the welding slag, and the water mist also reduces the smoke generated by welding in the air. s6. The second gear (66) is also driven to rotate by the second motor (13). The meshing of the second gear (66) and the first gear (65) drives the rotating rod (64) and the sponge plate (62) to rotate. The sponge plate (62) filters the water inlet bin (63) to prevent the welding slag in the water storage tank (4) from falling into the water inlet bin (63). The rotation of the sponge plate (62) will throw off the welding slag filtered on the sponge plate (62).
