The sliders 31 on both sides of the mobile frame 30 are respectively provided with screw holes 32 for connecting the screw rod 52 and connecting holes 33 for connecting the connecting rod, which drive the connected mobile frame 30; the cleaning mechanism is arranged at the bottom of the inner side of the mobile frame 30, including a vacuum cleaner 61 and a dust cover 62 connected to the vacuum cleaner 61, and a dust suction port is provided at the bottom of the dust cover 62, and a roller brush 63 is provided at the dust suction port; the dust-proof curtain 20 is arranged on one side of the mobile frame 30 perpendicular to the slide rail 40, and the width of the dust-proof curtain 20 is greater than or equal to the distance between the two slide rails 40.

[0031] The working principle of the above technical solution is as follows:

[0032] The initial position of the movable frame 30 is at the left end of the slide rail 40, that is, the dust curtain 20 is outside the spot welding table 10. When cleaning the spot welding table 10, start the first motor 51, and the screw rod 52 rotates to drive the movable frame 30 to translate along the slide rail 40. When moving, the roller brush 63 of the cleaning mechanism brushes the dust, and the vacuum cleaner 61 can absorb dust through the dust hood 62. When spot welding is required, the movable frame 30 returns to the initial position after cleaning is completed. After spot welding is completed, the above steps can be repeated and the movable frame 30 is moved to the other end of the slide rail 40. When moving, the dust curtain 20 can cover the spot welding table 10 to reduce the accumulation of dust on the spot welding table 10, thereby playing a dust prevention role.

[0033] In another embodiment, if Figure 3 As shown, the mobile frame 30 is provided with three spring clips 34 for clamping and connecting the dust curtain 20; the three spring clips 34 are respectively provided on both sides and the middle of the mobile frame 30, and the spring clip 34 in the middle is higher than the spring clips 34 on both sides. The dust curtain 20 is easy to disassemble, and the higher spring clip 34 in the middle can make the middle part of the dust curtain 20 away from the suction of the vacuum cleaner 61.

[0034] In another embodiment, if Figure 1 and Figure 4 As shown, a dovetail groove 41 is further provided on the top side of the opposite surface of the slide rail 40, and a limit strip 21 slidably connected to the dovetail groove 41 is provided on both sides of the dust curtain 20, and the limit strip 21 can be made of silicone. The dovetail groove 41 can cooperate with the limit strip 21 to support the edge of the dust curtain 20 to ensure that the dust curtain 20 completely covers the spot welding station 10.

[0035] In another embodiment, if Figure 5 As shown, the roller brushes 63 include two rollers, both of which are rotatably connected to the dust cover 62. Gears are respectively provided at one end of the two roller brushes 63, and the two gears mesh with each other. A second motor 64 is provided on the dust cover 62 to drive and connect one of the roller brushes 63; the bristles of the two roller brushes 63 are arranged staggered with each other. The second motor 64 can drive the two roller brushes 63 to rotate in opposite directions through the gears, so that the bottom sides of the two roller brushes 63 rotate in the direction between the two roller brushes during cleaning, which is conducive to brushing dust to concentrate between the two roller brushes 63, making it convenient for the vacuum cleaner 61 to collect dust and improving the dust collection efficiency; the staggered bristles prevent the bristles of the two rollers from interfering with each other to form resistance and affect dust collection.

[0036] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model.
