A fifth mounting slot 503g-1 is arranged in the middle of the pressing seat 503g. A stop block 503h is movably arranged in the fifth mounting slot 503g-1. A rotating hole 503h-1 and a clamping hole 503h-2 which are in communication are arranged in the stop block 503h. A rotating rod 503i is fixedly arranged in the rotating hole 503h-1. A torsional spring 503j is arranged in the rotating hole 503h-1. The torsional spring 503j is sleeved on the outer wall of the rotating rod 503i. One end of the torsional spring 503j is fixed to the outer wall of the rotating rod 503i. The other end of the torsional spring 503j is arranged in the clamping hole 503h-2.

[0047] In the embodiment, the inner side of the stop block 503h is an arc surface 503h-3. The top side of the storage box 503 is provided with a buckle plate 503k at a position corresponding to the buckle ring 502e.

[0048] The electrode cap is pressed into the second feeding hole 503a of the storage box 503 in sequence until the second feeding hole 503a is filled with the electrode cap, and then the stop block 503h is prevented from being pushed out of the second feeding hole 503a by the push block 503c under the action of the torsion spring 503j. The two limiting holes 503b on the storage box 503 are aligned with the two insertion rods 502a on the side wall of the material taking box 502, and the two insertion rods 502a are inserted into the two limiting holes 503b. When the storage box 503 is close to the material taking box 502, the pressing seat 503g enters the insertion slot 502d on the material taking box 502, and the inner side of the stop block 503h on the pressing seat 503g is an arc surface 503h-3. Therefore, the arc surface 503h-3 on the stop block 503h is pressed and driven to rotate by the pressing column 502d-2, so that the stop block 503h no longer blocks the electrode cap in the second feeding hole 503a. The electrode cap is pushed into the first feeding hole 502b of the material taking box 502 by the push block 503c, the buckle ring 502e is buckled on the buckle plate 503k, and the material taking box 502 and the storage box 503 are fixed together to ensure that the welding gun can install the electrode cap through the cap taking port 502c.

[0049] Working principle: when the electrode cap on the welding gun needs to be ground, the PLC controller in the operation control box 2 controls the rotation of the motor 201a, the output shaft of the motor 201a rotates and drives the involute cylindrical helical gear 201b to rotate, and then drives the bevel gear 202c to rotate, so the bevel gear 202c drives the first cap removal gear 402 to rotate through the second transmission gear 202b. Since the first cap removal gear 402 is meshed with the second cap removal gear 404 and the first transmission gear 303 on both sides, the first cap removal gear 402 can drive the rotation of the mounting seat 302 in the grinding mechanism 300, and the electrode cap that needs to be ground is inserted into the insertion hole 301d of the plastic sheet 301c and reaches the fan-shaped table 304c in the middle of the tool seat 304a. When the mounting seat 302 rotates, the cutter 304e on the side of the fan-shaped table 304c on the mounting seat 302 grinds the electrode cap. Compressed air is introduced into the air amplifier 305 (which is an existing device, and the principle is not described here), and the compressed air introduced into the air amplifier 305 serves as a power source to drive the surrounding air flow to form high-pressure and high-speed airflow, generating suction. The waste generated by the electrode cap being ground by the cutter 304e is collected in the collection box 1a through the suction channel 301a and the feed pipe 305a. When the electrode cap needs to be replaced after being ground several times, the electrode cap above the welding gun is inserted into the cap removal hole c of the upper cap removal assembly 401 of the upper cap removal assembly 401, and the PLC controller controls the motor 201a to periodically reverse. When the first cap removal gear 402 rotates clockwise, the second cap removal gear 404 will rotate counterclockwise, and the first cap removal gear 402 will rotate clockwise by pressing the swing part 408a of the clamping block 408 around the connecting shaft e through the driving groove h, until the clamping surface 408b on the inner side of the clamping block 408 clamps the electrode cap. At this time, the continuous rotation of the first cap removal gear 402 will clamp the electrode cap with the welding gun by rotating the clamping block 408 and the electrode cap. When the welding gun is lifted up, the electrode cap can be separated from the welding gun. Then the electrode cap below the welding gun is inserted into the cap removal hole c of the lower cap removal assembly 403, the motor 201a is reversed, the first cap removal gear 402 is counterclockwise, and the second cap removal gear 404 is clockwise. The counterclockwise rotation of the first cap removal gear 402 will drive the swing part 408a of the clamping block 408 around the connecting shaft e to rotate counterclockwise and release the electrode cap. The electrode cap falls naturally from the upper cap removal assembly 401 due to gravity. When the second cap removal gear 404 rotates clockwise, the clamping block 408 in the lower cap removal assembly 403 clamps the electrode cap as described above. At this time, the welding gun is pressed down, so that the electrode cap is separated from the welding gun. If the motor 201a is reversed again, the electrode cap in the lower cap removal assembly 403 will fall naturally due to gravity, and the upper cap removal assembly 401 will clamp the electrode cap inserted into the cap removal hole c.Therefore, each reverse rotation of the rotating motor 201a can realize one clamping and one separation of the electrode cap through the upper cap unloading assembly 401 and the lower cap unloading assembly 403, compared with the prior art that realizes the unloading and separation of the electrode cap through one forward rotation and one reverse rotation, the loss of the rotating motor 201a caused by frequent forward and reverse rotation is reduced, and after the electrode cap on the welding gun is unloaded, the welding gun can install the electrode cap through the cap taking port 502c.
