The protection component 20 has a light filtering member 21 for surrounding the workpiece. The protection component 20 is used to move along with the welding position of the workpiece so that the light filtering member 21 filters the strong welding light; the gas collection component 30 is arranged on the base 10 and is located on the side of the welding table 13 away from the welding robot 14. The gas collection component 30 is used to collect welding waste gas towards the welding table 13.

[0024] It should be noted that a clamping and positioning component can be provided on the welding table 13 to fix the workpiece placed inside the welding table 13 and prevent the workpiece from shifting during the welding process, resulting in welding errors; the welding robot 14 can be an arc welding robot, which can achieve continuous path control and point position control under the control of a computer, and has the characteristics of being able to perform welding operations for a long time, ensuring high productivity, high quality, and high stability of welding operations; the light filtering member 21 can be an electric welding light filter, which can make the observed brightness at the welding position darker and can observe the welding effect during the welding operation; the light filtering member 21 can be annular, enabling technicians to observe the welding effect at any position around the welding table 13 area; the air inlet of the gas collection component 30 is located above the workpiece, facilitating the inhalation of waste gas generated during welding.

[0025] The beneficial effects of the robot welding protection device provided by the present utility model are as follows: Compared with the prior art, the present utility model adopts a protection component 20 slidably connected to the fixing seat 11, enabling the light filtering member 21 to change its relative position with respect to the fixing seat 11. When the welding position changes, the position of the light filtering member 21 is moved to always block the strong light generated during the welding process. The operator can directly observe the welding effect through the light filtering member 21 without observing after stopping the machine, which can improve the welding efficiency while protecting the health of the operator's eyes; the gas collection component 30 is connected to the fixing seat 11, can collect the waste gas generated inside the welding table 13 during the welding process, prevent the operator from inhaling the waste gas, is beneficial to protecting the physical health of the operator, and improves the safety of device use.

[0026] In a possible implementation manner, please refer to Figure 2 and Figure 3, the protection component 20 includes a sliding seat 22, a telescopic driving member 23, and a light filtering member 21; the sliding seat 22 has two sliding ends, and the two sliding ends are respectively slidably connected to the two sliding grooves 12. An installation hole 221 is provided on the sliding seat 22, and the installation hole 221 is aligned with the soldering station 13; the telescopic driving member 23 is arranged on the base 10, and the output end is connected to the sliding seat 22; the light filtering member 21 is connected in the installation hole 221 and extends upward.

[0027] It should be noted that the sliding seat 22 slides inside the sliding groove 12 under the driving action of the telescopic driving member 23, which can change the relative position between the light filtering member 21 and the fixed seat 11. When the welding position changes, the position of the light filtering member 21 can be adjusted in time, so that the light filtering member 21 can surround the welding position, enabling the operator to directly observe the welding effect during welding observation, protecting the health of the operator's eyes while improving the welding efficiency.

[0028] In a possible implementation, please refer to Figure 3 , the telescopic driving member 23 includes a lead screw 231 and a driving motor 232; the lead screw 231 is rotatably connected to one of the fixed seats 11, and the lead screw 231 is in threaded cooperation with the sliding seat 22; the output end of the driving motor 232 is connected to one end of the lead screw 231.

[0029] It should be noted that there can be two telescopic driving members 23, both having a lead screw 231 and a driving motor 232. The two lead screws 231 are respectively rotatably connected to the two fixed seats 11; the driving motor 232 provides rotational power for the lead screw 231, causing the lead screw 231 to rotate on the base 10, and enabling the sliding seat 22 in threaded cooperation with the lead screw 231 to slide along the direction of the lead screw 231. When it is necessary to change the welding position, the relative position between the sliding seat 22 and the workpiece is controlled by the forward and reverse rotation of the driving motor 232, so that the light filtering member 21 can shield the welding position and improve the welding efficiency.

[0030] In a possible implementation, please refer to Figure 3 , the light filtering member 21 is slidably connected up and down to the installation hole 221; at least one lifting driving member 24 is provided on the sliding seat 22, and the lifting driving member 24 is connected to the light filtering member 21, and the lifting driving member 24 is used to drive the light filtering member 21 to slide up and down.

[0031] It should be noted that the filter element 21 can be slidably connected to the mounting hole 221, capable of moving along with the slide base 22 within the sliding groove 12 and also capable of moving in the vertical direction. When the welding robot 14 welds the workpiece, the filter element 21 can slide downward along with the slide base 22 to shield the welding position. When it is necessary to change the welding position, the filter element 21 slides upward and horizontally driven by the slide base 22. The slidably arranged filter element 21 can effectively shield the welding position and avoid touching the workpiece when changing the shielded welding position, which can improve the welding efficiency.

[0032] In a possible implementation, please refer to Figure 3 , the lifting drive member 24 includes a rotary power member 241, a gear 242, and a rack 243. The rotary power member 241 is arranged on the slide base 22. The gear 242 is connected to the output end of the rotary power member 241. The rack 243 is vertically arranged on the side wall of the filter element 21 and is meshed with the gear 242.

[0033] It should be noted that the rotary power member 241 can be a servo motor, capable of controlling the rotation speed to achieve the purpose of controlling the height of the filter element 21. A receiving groove for accommodating the rack 243 can be provided on the inner wall of the mounting hole 221, which can avoid affecting the close fit between the filter element 21 and the mounting hole 221, and enable the filter element 21 to be clamped in the receiving groove of the mounting hole 221 for vertical movement, preventing the filter element 21 from rotating and being misaligned, which may affect the normal use of the device. The rack 243 is located in the receiving groove and can slide within the receiving groove to drive the filter element 21 to move vertically. The gear 242 is connected to the output end of the rotary power member 241 and is meshed with the rack 243. By controlling the forward and reverse rotation of the gear 242, the rack 243 can move up and down. Both the gear 242 and the rack 243 can be provided in two groups, respectively located on the opposite sides of the slide base 22, so that the filter element 21 is balanced in force during the up and down sliding process, enabling the filter element 21 to smoothly shield the welding position.

[0034] In a possible implementation, please refer to Figure 1 and Figure 2 , a plurality of suction holes 15 are provided on the fixed base 11. The suction holes 15 are all located above the welding table 13 and are all connected to the gas collection assembly 30.

[0035] It should be noted that the suction holes 15 are arranged at intervals in the horizontal direction, capable of sucking the air inside the entire welding table 13. The suction holes 15 are located between the welding table 13 and the filter element 21. When welding the workpiece, while the filter element 21 shields the workpiece, the harmful gases generated by high-temperature welding above the workpiece can be extracted, and the harmful gases are collected through the gas collection assembly 30, which is beneficial to protecting the personal health of the operators exposed to the welding environment.

[0036] In a possible implementation, please refer to Figure 1 and Figure 2 , a limiting plate 16 is provided on the fixing base 11. The limiting plate 16 is located above the air suction hole 15 and is used to abut against the bottom of the light filtering member 21.

[0037] It should be noted that when the bottom end of the light filtering member 21 is at the lowest position, it abuts against the limiting plate 16, so that there is a certain distance between the light filtering member 21 and the soldering station 13, which helps the waste gas generated by welding to disperse from the bottom of the light filtering member 21 and prevents the light filtering member 21 from blocking the soldering station 13 and unable to discharge the waste gas.

[0038] In a possible implementation, please refer to Figure 1 and Figure 2 , the gas collecting assembly 30 includes a gas collecting pipe 31 and a gas collecting box 32; the gas collecting pipe 31 has a plurality of air inlet ports, and each air inlet port is respectively communicated with each air suction hole 15, and the gas collecting pipe 31 is communicated with the gas collecting box 32; the gas collecting box 32 is used for collecting and filtering the waste gas collected in the gas collecting pipe 31.

[0039] It should be noted that the gas collecting pipe 31 has a plurality of air inlet ports and an air outlet. The plurality of air inlet ports are uniformly distributed above the soldering station 13 area, which can effectively collect the waste gas generated inside the soldering station 13 area and prevent the waste gas from leaking. The collected waste gas enters the gas collecting box 32 through the air outlet for filtering, and the waste gas in the gas collecting pipe 31 is retained in the gas collecting box 32.

[0040] In a possible implementation, please refer to Figure 4 , a filter element 321 is provided inside the gas collecting box 32.

[0041] It should be noted that the waste gas enters the gas collecting pipe 31 through each air suction hole 15 and converges and then enters the gas collecting box 32 together. The filter element 321 inside the gas collecting box 32 can be activated carbon. When the waste gas enters the gas collecting box 32, it is adsorbed by the filter element 321 and retained in the filter element 321. The filtered air is discharged from the gas collecting box 32 to complete the filtration of the waste gas and protect the physical health of the operator.

[0042] In a possible implementation, please refer to Figure 4 , a fan 322 is provided on the gas collecting box 32, and the fan 322 is used to form a negative pressure inside the gas collecting box 32.

[0043] It should be noted that the fan 322 is provided on one side of the gas collecting box 32 away from the gas collecting pipe 31. The high-speed rotating fan 322 can suck the air inside the gas collecting box 32 and extract the waste gas generated during welding through the gas collecting pipe 31 and the air suction hole 15, so that the air inside the soldering station 13 enters the air suction hole 15, avoiding the operator from inhaling the waste gas, being beneficial to protecting the physical health of the operator and improving the safety of the device during use.

[0044] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
