DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1, reference Figures 1 to 9 , which is the first embodiment of the present invention, provides a roller processing welding device that can achieve the effect of cleaning welding slag, and includes a welding support seat 100, on which a welding gun 102 and a movable mechanism 200 are respectively connected through a welding robot arm 101, and a slag removal mechanism 300, a driving mechanism 400, and a cleaning mechanism 500 are respectively arranged inside the movable mechanism 200, and a rotating fixture 103 is provided on the welding support seat 100, and a roller body 104 is arranged on the outside of the rotating fixture 103.

[0030] Among them, the setting of the welding support seat 100 can effectively support the welding robot arm 101, the welding gun 102 is fixedly connected to the welding robot arm 101, the movable mechanism 200 is rotatably connected to the welding robot arm 101, and there is friction resistance between the movable mechanism 200 and the welding robot arm 101 during rotation, which can ensure that when the movable mechanism 200 rotates to a specified position around the welding robot arm 101, the movable mechanism 200 can be limited by the friction resistance, the setting of the slag removal mechanism 300 can effectively remove welding slag from the welding position, the setting of the cleaning mechanism 500 can perform surface cleaning on the welding position, and the driving mechanism 400 can drive the slag removal mechanism 300 and the cleaning mechanism 500.

[0031] The movable mechanism 200 includes a rotating arm 201 rotatably connected to the welding robot arm 101. A plurality of barrier strips for increasing friction are arranged between the rotating arm 201 and the welding robot arm 101 to ensure that when the rotating arm 201 rotates around the welding robot arm 101 to a specified position, the rotating arm 201 can be limited by the friction resistance of the barrier strips. A containing box 202 is fixedly connected to the bottom of the rotating arm 201. The containing box 202 is made of metal. The metal material has stronger rigidity. The containing box 202 made of metal can protect the components inside it. One side of the containing box 202 is in an open shape. The opening-shaped setting can extend the components inside it, so that the welding position can be cleaned.

[0032] The slag removal mechanism 300 includes a movable plate 301 and a stop column 302. A rectangular groove 303 and a stop groove 304 are respectively provided inside the movable plate 301. Figure 6 The movable plate 301 is slidably connected to the containing box 202 through an arc groove. The setting of the arc groove can effectively limit the movable plate 301, and a gap is left between the bottom of the movable plate 301 and the opening extension of the containing box 202 to prevent the welding slag from contacting the movable plate 301 when cleaning the welding slag. The inside of the rectangular groove 303 is connected to a telescopic plate 306 through a first spring 305. The setting of the telescopic plate 306 can better transmit the thrust on the slide plate 307 to the first spring 305.

[0033] Furthermore, the setting of the stop column 302 can resist the movable plate 301, and the setting of the rectangular groove 303 and the limiting groove 304 can limit the first spring 305 and the slide plate 307 therein. The movable plate 301 is slidably connected to the accommodating box 202, which can ensure that the bottom of the movable plate 301 will not pass over the opening of the accommodating box 202 during the movement, so as to prevent the movable plate 301 from contacting the welding part of the roller body 104 during the movement, and to prevent the movable plate 301 from contacting the welding slag on the roller body 104. The setting of the first spring 305 can limit the telescopic plate 306. When the telescopic plate 306 moves toward the first spring 305, the telescopic plate 306 squeezes the first spring 305, and the first spring 305 accumulates elastic potential energy after contraction. When the driving force of the telescopic plate 306 fails, the elastic potential energy of the first spring 305 is converted into kinetic energy for resetting the telescopic plate 306, so that the telescopic plate 306 can be effectively reset.

[0034] A slide plate 307 is provided between the telescopic plate 306 and the limiting groove 304, and a slag removal plate 308 is fixedly connected to the end of the slide plate 307 away from the telescopic plate 306. The slag removal plate 308 can be set to remove slag from the welding part of the drum body 104. A lifting surface 309 and a contact surface 310 are respectively provided on the movable plate 301 and the slag removal plate 308. The setting of the lifting surface 309 and the contact surface 310 can ensure that the slag removal plate 308 drives the slag removal plate 308 to be lifted when encountering relatively firmly fixed welding slag, so as to avoid damage to the slag removal plate 308. A first A shovel surface 311 and a second shovel surface 312 are provided with a spacing groove 313 between the first shovel surface 311 and the second shovel surface 312. The setting of the spacing groove 313 can ensure that when the first shovel surface 311 passes over relatively solid welding slag, the second shovel surface 312 can scrape it a second time. When the second shovel surface 312 fails, the slag removal plate 308 will rise a second time, so that the relatively solid welding slag passes over this cleaning. When the drum body 104 completes a complete rotation, the first shovel surface 311 and the second shovel surface 312 will clean it a second time, and it can be cleaned twice for each rotation.

[0035] Further, the movable plate 301 is slidably connected to the containing box 202, the support column 302 is fixedly connected to the containing box 202, one end of the slag removal plate 308 is in contact with the containing box 202, and a gap is provided between the other end and the containing box 202, and the gap between the slag removal plate 308 and the containing box 202 allows the welding slag in the spacing groove 313 to be discharged. The telescopic plate 306 is slidably connected to the rectangular groove 303, and the telescopic plate 306 is slidably connected to the slide plate 307, both ends of the slide plate 307 are in contact with the inner wall of the limiting groove 304, the lifting surface 309 is adapted to the contact surface 310, the movable plate 301 is adapted to the support column 302, the cross section of the support column 302 is semicircular, the first shovel surface 311 and the second shovel surface 312 are both planes, and a reset spring 314 is provided between the limiting groove 304 and the slide plate 307, and the setting of the reset spring 314 can better drive the slide plate 307 to reset. There are multiple first springs 305 , which are distributed in a linear array between the telescopic plate 306 and the rectangular groove 303 . The first springs 305 are fixedly connected to the rectangular groove 303 and the telescopic plate 306 , respectively. The arrangement of multiple first springs 305 can increase the resetting ability of the telescopic plate 306 .

[0036] In summary, the slag removal mechanism 300 can effectively remove welding slag from the welding area, the cleaning mechanism 500 can clean the surface of the welding area, and the driving mechanism 400 can drive the slag removal mechanism 300 and the cleaning mechanism 500 to operate.

[0037] Example 2, reference Figure 1 to Figure 4, which is the second embodiment of the present invention. The difference from the previous embodiment is the driving mechanism 400. This embodiment provides a driving mechanism 400 for the roller processing welding device, which solves the driving problem of the slag removal mechanism 300 and the cleaning mechanism 500. It includes a second spring 401 and a rubber column 402 fixed at both ends of the movable plate 301. The other end of the rubber column 402 is fixedly connected to a driven plate 403. The side of the driven plate 403 close to the movable plate 301 is attached with a convex column 404. The side of the outer wall of the container box 202 close to the convex column 404 is fixedly connected to a driving motor 405. The driving end of the driving motor 405 penetrates the container box 202 and is fixedly connected to the convex column 404. The end of the second spring 401 away from the movable plate 301 is fixedly connected to the container box 202.

[0038] Among them, the setting of the second spring 401 can drive the movable plate 301 to reset after it moves. The rubber column 402 is made of elastic material, which can drive the movable plate 301 to move while correcting the movement deviation between the driven plate 403 and the movable plate 301. The movement of the driven plate 403 can drive the movable plate 301 to move, so that the movement trajectory of the movable plate 301 and the movement trajectory of the driven plate 403 can deviate. The driven plate 403 will move to the end away from the movable plate 301 under the resistance of the convex column 404. After the movement, the driven plate 403 will drive the movable plate 301 to follow the movement under the limiting action of the rubber column 402. The setting of the drive motor 405 can drive the convex column 404 to rotate.

[0039] The driving end of the driving motor 405 is located outside the containing box 202 and is fixedly connected to a first gear 406 . The first gear 406 is meshed with a second gear 408 through a toothed chain 407 . The shaft end of the second gear 408 passes through the containing box 202 and is fixedly connected to a rotating column 409 .

[0040] Furthermore, when the driving motor 405 drives the first gear 406 to rotate, it drives the toothed chain 407 to operate, the toothed chain 407 drives the second gear 408 to rotate, and the second gear 408 drives the rotating column 409 to rotate. The rotating column 409 is made of rubber and has a certain deformation ability.

[0041] The rest of the structure is the same as that of Example 1.

[0042] In summary, the driven plate 403 will move to the end away from the movable plate 301 under the resistance of the boss 404, and after moving, the driven plate 403 will drive the movable plate 301 to move with it under the limiting action of the rubber column 402, and the setting of the driving motor 405 can drive the boss 404 to rotate.

[0043] Example 3, reference Figure 1 to Figure 6, which is the third embodiment of the present invention, and is different from the previous embodiment in that the cleaning mechanism 500 is provided. This embodiment provides a cleaning mechanism 500 of a roller processing and welding device, which solves the problem of cleaning the weld surface of the roller body 104. The cleaning mechanism 500 includes a discharge door 501 hingedly connected to the bottom of the accommodating box 202, and also includes a cleaning wire 502 fixedly connected to the circumference of the rotating column 409. The bottom of the open end of the accommodating box 202 is fixedly connected with a leakproof plate 503, and the bottom of the leakproof plate 503 is provided with a concave surface 504 adapted to the accommodating box 202. The side of the accommodating box 202 close to the leakproof plate 503 is fixedly connected with a connecting rod 505, and the connecting rod 505 is fixedly connected with an extrusion column 506 through a torsion spring. The leakproof plate 503 is made of rubber, and the leakproof plate 503 fits the extrusion column 506.

[0044] Among them, the setting of the discharge door 501 can effectively discharge the materials inside the containing box 202, the setting of the cleaning wire 502 can clean the welding points and remove the loose welding slag, the setting of the leakproof plate 503 can block the welding slag and prevent the cleaning wire 502 from throwing out the cleaned welding slag during the rotation process, thereby improving the safety of the device and reducing the release of dust inside it, and the setting of the extrusion column 506 can ensure the position of the leakproof plate 503 so that it can better fit with the drum body 104.

[0045] Furthermore, the arrangement of the lifting surface 309 and the contact surface 310 can ensure that the slag removal plate 308 is lifted when encountering relatively firmly fixed welding slag, thereby avoiding damage to the slag removal plate 308. A first shoveling surface 311 and a second shoveling surface 312 are respectively provided on one side of the slag removal plate 308, and a spacing groove 313 is provided between the first shoveling surface 311 and the second shoveling surface 312. The arrangement of the spacing groove 313 can ensure that when the first shoveling surface 311 passes over the relatively firm welding slag, the second shoveling surface 312 can shovel it a second time. When the second shoveling surface 312 fails, the slag removal plate 308 will rise a second time, so that the relatively firm welding slag passes over this cleaning. When the drum body 104 completes a complete rotation, the first shoveling surface 311 and the second shoveling surface 312 will clean it a second time, and it can be cleaned twice for each rotation.

[0046] The rest of the structure is the same as that of Example 2.

[0047] During operation, the drum body 104 is placed in the rotating fixture 103, the rotating fixture 103 and the welding gun 102 are started, and the welding gun 102 welds the drum body 104 outside the rotating fixture 103. After the rotating fixture 103 drives the drum body 104 to rotate one circle, the welding work can be completed. After the welding is completed, wait for the drum body 104 to cool down for a period of time, and then rotate the movable mechanism 200 downward so that the cleaning box on the movable mechanism 200 fits with the drum body 104. At this time, start the rotating fixture 103, and the rotating fixture 103 drives the drum body 104 to rotate, and the welding part of the drum body 104 fits with the containing box 202.

[0048] The driving motor 405 is started, and the driving motor 405 drives the first gear 406 to rotate, and the first gear 406 drives the toothed chain 407 to operate and drives the second gear 408 to rotate, and the rotation of the second gear 408 drives the rotating column 409 to rotate, and the cleaning wire 502 on the rotating column 409 performs preliminary cleaning of the welding slag at the welding position;

[0049] When the first gear 406 rotates, it drives the boss 404 to rotate. When the convex end of the boss 404 contacts the driven plate 403, the driven plate 403 is resisted and moves to the end away from the boss 404. The movement of the driven plate 403 drives the movable plate 301 to move. The movement of the movable plate 301 drives the second spring 401 to stretch and accumulate elastic potential energy. The movement of the movable plate 301 drives the first spring 305, the telescopic plate 306 and the slide plate 307 to move. The slide plate 307 drives the slag removal plate 308 to move slightly forward for a distance. At this time, the slag removal plate 308 contacts the welding slag. At this time, the welding slag moves toward the slag removal plate The first spring 305 is pressed against the first shovel surface 311 when the welding slag is relatively solid, so that the contact surface 310 on the slag removal plate 308 contacts the lifting surface 309. When the lifting surface 309 contacts the contact surface 310, the movable plate 301 contacts the stop column 302, so that the movable plate 301 is limited. At this time, the slide plate 307 and the slag removal plate 308 move toward the lifting surface 309 and the slide plate 307 presses the reset spring 314, so that the first shovel surface 311 is separated from the welding slag.

[0050] The reset spring piece 314 drives the slide plate 307 to reset, and the first spring 305 drives the telescopic plate 306, the slide plate 307, and the slag removal plate 308 to reset, and drives the second shovel surface 312 to directly impact the welding slag, thereby removing the welding slag. If the welding slag has not been removed at this time, the second shovel surface 312 is driven to move in the direction of the first spring 305, so that the contact surface 310 on the slag removal plate 308 contacts the lifting surface 309. When the lifting surface 309 contacts the contact surface 310, it will drive the movable plate 301 to contact the support column 302, so that the movable plate 301 is limited. At this time, the slide plate 307 and the slag removal plate 308 move toward the lifting surface 309 to separate the second shovel surface 312 from the welding slag. When the drum body 104 rotates into the second circle, it can be cleaned again.

[0051] In summary, the arrangement of the lifting surface 309 and the contact surface 310 can ensure that the slag removal plate 308 is lifted when encountering relatively firmly fixed welding slag, thereby avoiding damage to the slag removal plate 308.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be included in the scope of the claims of the present invention.
