The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art.

As shown in fig. 1 and 2, an embodiment of the present application provides an electrode replacement device, which includes a housing 101, a mounting unit 201, and a rotating unit 301.

The casing 101 accommodates the mounting unit 201 and the rotating unit 301 inside, so that the mounting unit 201 and the rotating unit 301 form a position-stable whole, the electrode 102 is detached as a welding consumable at the whole formed by the mounting unit 201 and the rotating unit 301, manual operation is not needed, and the automation degree is high.

In some examples, the electrode replacing apparatus further includes a frame 501, where the frame 501 is on the ground, and keeps the position stable, and the housing 101 is mounted to the frame 501, so that the housing 101 and the mounting unit 201 and the rotating unit 301 inside are position stable. The housing 101 can protect the mounting unit 201 and the rotating unit 301 on the premise of ensuring the positions of the mounting unit 201 and the rotating unit 301.

Further, the mounting unit 201 is provided with a jack 202, and the aperture of the jack 202 is slightly larger than the outer diameter of the electrode 102, so that the electrode 102 can be conveniently inserted. The electrode 102 can be automatically removed after being inserted into the receptacle 202.

Wherein, a plurality of clamping structures 203 are disposed on the mounting unit 201, each clamping structure 203 is movably connected with the mounting unit 201, and each clamping structure 203 can clamp or release the electrode 102 through movement on the mounting unit 201. It can be appreciated that when the electrode 102 needs to be disassembled, each clamping structure 203 clamps the electrode 102, and applies a pre-tightening force to the electrode 102; when the removal of the electrode 102 is completed, each of the gripping structures 203 releases the electrode 102, facilitating the removal of the discarded electrode 102 from the electrode changing device.

Specifically, the clamping structures 203 are approximately uniformly distributed at the edge of the jack 202, so that the contact positions of the clamping structures 203 and the electrode 102 are relatively uniformly positioned on the side wall of the electrode 102, and the electrode 102 is prevented from being locally stressed too much to hinder the disassembly of the electrode 102.

Meanwhile, the rotation unit 301 is disposed in parallel with the mounting unit 201 in the housing 101, and the rotation unit 301 is approximately coaxial with the mounting unit 201. The mounting unit 201 is fixedly connected to the inside of the housing 101, and the rotating unit 301 can rotate inside the housing 101, thereby achieving relative rotation of the rotating unit 301 and the mounting unit 201.

The rotation unit 301 drives each of the holding structures 203 by rotation with respect to the mounting unit 201 so that each of the holding structures 203 approaches or separates from each other. It will be appreciated that when the clamping structures 203 are brought into close proximity to one another, each clamping structure 203 clamps an electrode 102 within the receptacle 202; when the clamping structures 203 are moved away from each other, each clamping structure 203 releases the electrode 102 within the receptacle 202.

As shown in fig. 4, in some examples, the electrode replacement apparatus further includes a first power unit 304, where the first power unit 304 drives the rotating unit 301 to rotate, thereby driving the clamping structures 203 toward and away from each other.

Further, the first power unit 304 is disposed on the housing 101, and an output end of the first power unit 304 extends into the housing 101 by using a device that outputs linear motion. Meanwhile, the rotating unit 301 is provided with an extension portion 302, and the extension portion 302 extends to the position of the output end of the first power unit 304 and is hinged to the output end of the first power unit 304. With the linear motion of the output end of the first power unit 304, the inclination angle of the extension portion 302 changes, that is, the rotation unit 301 rotates.

As shown in fig. 5, in some examples, the clamping unit includes a working end 204, the working end 204 for abutting the electrode 102 within the receptacle 202. Each of the clamping structures 203 is rotatably connected with the mounting unit 201, and the clamping structures 203 are configured as non-revolution bodies, and when the clamping structures 203 rotate, the inclination angle of the clamping structures 203 changes, so that the working end 204 gradually enters the range of the jack 202 or gradually leaves the range of the jack 202.

It can be understood that the shape of the working end 204 corresponds to the shape of the outer wall of the electrode 102, and when each working end 204 clamps the electrode 102 in the jack 202 in an abutting manner, the contact area between the working end 204 and the electrode 102 is increased, so as to ensure the effectiveness of the clamping effect.

In some examples, the clamping structure 203 further includes a mating end 205, and the clamping structure 203 can be rotated by manipulating the mating end 205, as the mating end 205 is integral with the working end 204, during which the working end 204 can clamp or release the electrode 102 within the receptacle 202.

Further, the rotation unit 301 is provided with a fitting hole, and each of the holding structures 203 is within the range of the fitting hole. When the rotating unit 301 rotates relative to the mounting unit 201, the inner wall of the mating hole mates with each mating end 205, so that the rotating unit 301 and each clamping structure 203 are linked, and each clamping structure 203 is driven to rotate.

Specifically, to enable the rotation unit 301 and each clamping structure 203 to form a linkage, the inner wall of the mating hole is provided with a plurality of driving grooves 303, the number of the driving grooves 303 is equal to that of the clamping structures 203, and the mating ends 205 of each clamping structure 203 are respectively embedded into each driving groove 303. When the rotation unit 301 rotates relative to the mounting unit 201, the inner wall of the driving groove 303 applies a force to the mating end 205 to rotate the grip structure 203.

In addition, since the clamping structure 203 needs to have a certain rotational stroke to complete clamping and releasing of the electrode 102, the size of the driving groove 303 is larger than that of the mating end 205, leaving a margin for rotation of the clamping structure 203.

In some examples, the electrode replacing device further comprises an electrode containing unit 401, the rotating unit 301 is matched with the mounting unit 201 to complete the disassembly of the electrode 102, the electrode containing unit 401 is used for storing unused new electrode 102, and the welding equipment can mount the new electrode 102 at the position of the electrode containing unit 401, so that the electrode replacing device covers the disassembly process and the mounting process of the electrode 102, and the automation level of the replacement of the electrode 102 is further improved.

The electrode housing unit 401 is also disposed on the housing 101, and draws in the position where the electrode 102 is detached from the electrode 102. The electrode accommodating unit 401 is hollow, a plurality of electrodes 102 are positioned in the electrode accommodating unit 401, and each electrode 102 can sequentially move out of the range of the electrode accommodating unit 401, so that the electrodes 102 are installed, the electrodes 102 are not required to be frequently installed in an electrode replacing device, the labor cost is reduced, and the working efficiency is improved.

Specifically, the electrode housing unit 401 is formed in a substantially tubular structure, and a plurality of electrodes 102 are arranged in a linear array inside the electrode housing unit 401 and are removed at the ends of the electrode housing unit 401.

In some examples, one end of the electrode housing unit 401 is provided with an opening, and as the electrodes 102 inside the electrode housing unit 401 are sequentially mounted, each electrode 102 inside the electrode housing unit 401 is sequentially conveyed to the outside along the opening, that is, to a position to be used, in preparation for a subsequent electrode mounting work.

Further, a pushing component is disposed inside the electrode accommodating unit 401, and the pushing component is disposed at one end of the electrode accommodating unit 401 far away from the opening, and pushes the electrodes 102 in the electrode accommodating unit 401, so that each electrode 102 sequentially reaches the position to be used.

It can be understood that when the pushing assembly moves inside the electrode housing unit 401, each electrode 102 inside the electrode housing unit 401 moves as a whole.

In some examples, the pushing assembly includes a slider 402, a resilient structure 403. The elastic structure 403 may be a spring, and the shape of the slider 402 corresponds to the shape of the inner wall of the electrode housing unit 401. The elastic structure 403 is connected to the slider 402 on the one hand, and the elastic structure 403 is connected to an end of the electrode housing unit 401 remote from the opening on the other hand. The slider 402 abuts against the electrode 102 inside the electrode housing unit 401, facilitating the application of the urging force.

Further, when the electrode 102 is loaded inside the electrode housing unit 401, the elastic structure 403 is compressed. The compressed elastic structure 403 tends to return to its original state, and further provides a pushing force to the slider 402 in the opening direction, so that the electrode 102 in the electrode housing unit 401 is also subjected to a force in the same direction.

In some examples, the inner wall of the electrode housing unit 401 may be provided with a track, and the slider 402 is embedded in the track, so as to ensure that the slider 402 can perform linear motion along the track, and further ensure that the direction of the pushing force applied to the electrode 102 is stable.

In some examples, two electrode housing units 401 are provided, and the two electrode housing units 401 are respectively located at both sides of the case 101, and the number of electrode 102 loaded by the electrode replacement apparatus is increased. In addition, there is a difference in the directions of the openings of the two electrode housing units 401, facilitating the welding apparatus to mount the electrodes 102 in a plurality of directions.

In some examples, the position of the opening is provided with a clamping structure 404, the clamping structure 404 is hinged with the electrode containing unit 401, and the end shape of the clamping structure 404 is adapted to the shape of the outer wall of the electrode 102. When the electrode 102 is delivered to the location to be used, the electrode 102 is partially embedded in the clamping structure 404. It is understood that the clamping structure 404 can provide a pressing force toward the opening direction, so as to prevent the electrode 102 from falling off the electrode accommodating unit 401 in a clamping manner.

As shown in fig. 3, in some examples, a dust-proof assembly 503 is provided on the frame 501, and the dust-proof assembly 503 can cover the top of the electrode replacement apparatus, avoiding excessive dust in the external environment from entering the electrode replacement apparatus.

Specifically, the dust-proof assembly 503 includes a cover plate, and a connection structure, through which the cover plate is connected to the frame 501.

In some examples, the connection structure in the dust assembly 503 is rotatably coupled to the housing 501, and fig. 3 illustrates different positions of the dust assembly 503. When the electrode replacing device is idle, the connecting structure drives the cover plate to the top of the electrode replacing device through rotation; when the electrode replacing device is used, the cover plate is taken away from the top of the electrode replacing device by the connecting structure through rotation, and the connecting space between the external structure and the electrode replacing device is avoided.

Further, to drive the connection structure to rotate, a second power unit 502 is provided on the frame 501, and the second power unit 502 is hinged to the connection structure.
