Description

Technical Field

[0001] The invention relates to the field of baling machine preparation, in particular to a baling machine manufacturing welding visual recognition marking machine. Background Art

[0002] At present, when manufacturing a baler, it is necessary to first prepare the various panels of the baler, and then weld the various panels to form a baler. When selecting the welding method, an adaptive intelligent welding method is adopted, which can realize automatic tracking of welds, automatic adjustment of welding parameters, intelligent operation, and adapt to the complex welding requirements of the baler.

[0003] Converting welding process parameters into visually identifiable symbols is a key foundation for visual recognition of welding processes. To enable welding robots to autonomously identify different welds and weld trajectories, the current approach is to convert various welding postures (welding positions) and weld width parameters into visual recognition lines of different colors. These lines are then drawn at different locations on the plate for the welding robot to autonomously identify. Traditional line drawing methods, however, require manual labor and are relatively inefficient.

[0004] Patent CN201920624590.3 mentions an automatic line marking device based on visual recognition. In the above patent, its brush drawing component uses a single drawing pen for drawing lines, which can only draw monochrome lines. If welding lines of different colors need to be drawn, it is necessary to stop the machine and replace the drawing pen, which is very troublesome; in addition, the drive used for its translation is achieved by the cooperation of a pulley, a slide rail and a slider. In addition, the entire drawing component is installed on the same side of the slide rail, which will inevitably lead to the risk of the brush tilting.

[0005] Patent CN105500328A also mentions a leather marking device. The pen-changing mechanism in the above patent realizes the pen-changing action through the mutual cooperation of components such as an electromagnet, a first ratchet, a second ratchet, a rotating shaft, and an end cam. It adopts an action process similar to that of a press-type pen. This action method requires the use of many parts, and the entire action process is relatively complicated. Moreover, under this action principle, only adjacent pens can be changed in sequence. That is, if there are other pens between the pen that needs to be used later and the previously used pen, it is necessary to first switch from the previous pen to the middle pen, and then switch from the middle pen to the pen that needs to be used, which is very troublesome.

[0029] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0030] like Figures 1-9 A packaging machine manufacturing welding visual recognition line drawing machine shown, comprising The welding conveying assembly 1 includes a platform frame 11 and a conveying roller 12 installed on the platform frame 11 and used to convey the baler plate. The two sides of the conveying roller 12 are respectively installed on the platform frame 11 through the cooperation of bearings and bearing seats. A linkage sprocket is also installed at the end of the conveying roller 12. A linkage chain that cooperates with the linkage sprocket is also provided between adjacent conveying rollers 12. The synchronous and unidirectional rotation of all the conveying rollers 12 is achieved through the cooperation of the linkage sprocket and the linkage chain. Any one of the linkage chains is driven to rotate by a motor installed on the platform frame 11, thereby driving all the conveying rollers 12 to rotate, thereby realizing the transportation of the baler plate 13. The conveying direction of the conveying roller 12 is limited to a first direction, and the other horizontal direction perpendicular to the first direction is a second direction.

[0031] The self-propelled line drawing component 2 includes a self-propelled frame 20 that is arranged on a platform frame 12 and reciprocates along a first direction. The walking coordination between the self-propelled frame 20 and the platform frame 12 is as follows: a pair of self-propelled guide rails 14 distributed in parallel along a second direction are installed on the platform frame 11. The self-propelled guide rails 14 extend along the first direction. Self-propelled rollers 201 that roll on the self-propelled guide rails 14 are also installed at the bottom end of the self-propelled frame 20. There are four self-propelled rollers 201 in total, two in each group, distributed on the self-propelled frame 20, and The two self-propelled rollers 201 in the same group are matched with the same self-propelled guide rail 14. There is also a running groove recessed toward the inside of the self-propelled roller 201 in the middle position of the circumferential outer wall of the self-propelled roller 201. The self-propelled roller 201 is supported on the self-propelled guide rail 14, and the self-propelled guide rail 14 is placed in the running groove of the self-propelled roller 201. The design of the running groove is used to relatively limit the position of the self-propelled roller 201 on the self-propelled guide rail 14, so as to avoid the self-propelled roller 201 from running off when running on the self-propelled guide rail 14.

[0032] On the sides of the two self-propelled guide rails 14 of the platform frame 11, there are also two parallel self-propelled racks 15, which also extend along the first direction. A self-propelled gear 202 meshing with the self-propelled rack 15 is also installed at the bottom end of the self-propelled frame 20. The two self-propelled gears 202 are respectively driven by independent motors installed on the self-propelled frame 20 to rotate, thereby driving the self-propelled frame 20 to reciprocate along the first direction on the platform frame 11. For the travel coordination between the self-propelled frame 20 and the platform frame 12, the self-propelled guide rails 14 and the self-propelled rollers 201 are used to achieve travel, and the self-propelled racks 15 and the self-propelled gears 202 are used to provide travel drive. This can not only achieve smooth travel of the self-propelled frame 20, but also facilitate the installation and coordination between the self-propelled frame 20 and the platform frame 12. It is only necessary to hang the entire self-propelled frame 20 on the two self-propelled guide rails 14, which is very convenient.

[0033] A brush assembly is mounted on the self-propelled frame 20 and moves back and forth along the second direction. Figure 2 As shown in the schematic diagram, the brush assembly includes a brush traveling frame 211 arranged on the self-propelled frame 20 and reciprocating along the second direction. A brush lifting assembly, a brush rotating assembly, a brush ink supply assembly, a brush traveling drive assembly and a pen changing assembly are also installed on the brush traveling frame 211.

[0034] The reciprocating movement of the brush travel frame 211 on the self-propelled frame 20 is achieved through the cooperation of the brush travel drive assembly. Specifically, the brush travel drive assembly includes a brush travel slider 213, a brush travel gear 214 and a brush travel motor 212. The self-propelled frame 20 includes a pair of self-propelled seats 203 and a pair of self-propelled beams 204 installed on the self-propelled seats 203. The two sides of the self-propelled beams 204 are respectively supported on the two self-propelled seats 203. There is a gap between the two self-propelled beams 204. A brush travel guide rail 205 distributed in parallel along a first direction is respectively installed on the two self-propelled beams 204. The brush travel guide rail 205 extends along a second direction and is installed on the brush travel frame 211. There is a brush travel slider 213 that cooperates with the two brush travel guide rails 205. A brush travel rack 206 is also provided on the self-propelled beam 204 next to the self-propelled guide rail 205. The brush travel rack 206 also extends along the second direction. At the same time, a brush travel gear 214 that meshes with the brush travel rack 206 is installed on the brush travel frame 211. The two brush travel gears 214 are respectively driven to rotate by independent brush travel motors 212 installed on the brush travel frame 211, thereby driving the brush travel frame 211 to reciprocate along the second direction on the self-propelled frame 20. A gear bearing socket 215 is also provided between the brush travel gear 214 and the brush travel motor 212. The self-propelled frame 20 adopts a combination of a self-propelled seat 203 and a pair of self-propelled beams 204. When coordinated with the brush traveling frame 211, both sides of the brush traveling frame 211 are respectively supported on the self-propelled beams 204, thereby achieving stable support for the brush traveling frame 211, and providing an excellent foundation for the subsequent stable movement of the brush traveling frame 211 and the stable movement of the brush lifting assembly, brush rotating assembly, pen changing assembly and other components on the brush traveling frame 211.

[0035] like Figure 4-Figure 9 As shown in the schematic diagram, the pen replacement assembly includes a pen set mounting frame 3, a brush selection assembly, an inner pen holder assembly, an outer pen holder assembly and a welding brush 331.

[0036] The brush selection component, the inner pen holder component, the outer pen holder component and the weld brush are all installed on the pen group mounting frame 3. The inner pen holder component has several inner array brushes 311, and the outer pen holder component has several outer array brushes 321. There is a drawing position on the pen group mounting frame 3. By rotating the inner pen holder component or the outer pen holder component, different inner array brushes or outer array brushes can be switched to the drawing position. In the drawing position, the weld brush 331, the inner array brush 311 and the outer array brush 321 are distributed in sequence. The cooperation of the brush selection component realizes the grabbing and synchronization of the inner array brush 311 and the outer array brush 321 in the drawing position.

[0037] Specifically, such as Figure 6 As can be seen from the schematic diagram shown, the pen set mounting frame 3 includes an upper frame plate 301 and a lower frame plate 302 distributed up and down, and an upper and lower frame plate connecting rod 303 for connecting the upper frame plate 301 and the lower frame plate 302. The upper frame plate 301 and the lower frame plate 302 are both a flat plate structure, and the upper frame plate 301 and the lower frame plate 302 are balanced with each other. There are four upper and lower frame plate connecting rods 303, which are distributed in the shape of a U between the upper frame plate 301 and the lower frame plate 302, and the upper and lower sides of the upper and lower frame plate connecting rods 303 are fixed between the upper frame plate 301 and the lower frame plate 302 respectively.

[0038] An opening 304 is provided on one side of the upper frame plate 301, and a groove 305 with a notch opposite to the other side of the opening 304 is inlaid on the upper frame plate 301, and the two grooves 305 cooperate to form a pen-taking reciprocating slide. A brush assembly mounting seat 306 is installed on the lower frame plate 302. The brush assembly mounting seat 306 is a stepped structure composed of a first mounting seat and a second mounting seat. The size of the first mounting seat is larger than that of the second mounting seat. The first mounting seat is used to cooperate with the outer pen holder assembly, and the second mounting seat is used to cooperate with the inner pen holder assembly. A weld brush mounting hole 307 is also provided on the lower frame plate 302 below the opening 304 of the upper frame plate 301. The weld brush mounting hole 307 is used to realize the installation of the weld brush 331.

[0039] The weld brush 331 is disposed in the weld brush mounting hole 307 and is directly fixed to the lower frame plate 302 , thereby moving along with the entire pen assembly mounting frame 3 .

[0040] A pen group mounting frame lifting guide rod 309 and a pen holder replacement mounting seat 308 are also provided on the pen group mounting frame 3. The pen group mounting frame lifting guide rod 309 and the pen holder replacement mounting seat 308 are both installed on the upper frame plate. Among them, the pen group mounting frame lifting guide rod 309 is used for guiding during the lifting process of the pen group mounting frame, and the pen holder replacement mounting seat 308 is used for connecting the pen group mounting frame 3 with the marking machine. Through the joint cooperation of the pen group mounting frame lifting guide rod 309 and the pen holder replacement mounting seat 308, it is convenient for the marking machine to drive the pen group mounting frame 3 to move up and down stably.

[0041] like Figure 7 As shown in the schematic diagram, the inner pen holder assembly includes an inner brush swing plate 312 and an inner array brush 311 installed on the inner brush swing plate 312. There are several inner array brushes 311 distributed in an arc shape on the inner brush swing plate 312. At the same time, the inner brush swing plate 312 is also provided with through holes for each inner array brush 311 to pass through and move up and down. A first return spring 313 is installed on the outer wall of the inner array brush 311.

[0042] The inner brush swing plate 312 is installed below the lower frame plate 302, and a gap is left between the inner brush swing plate 312 and the lower frame plate 302. The inner brush swing plate 312 is driven to rotate by a first motor 314 installed on the brush assembly mounting seat 306 and a gear pair. The first motor 314 is installed on the second mounting seat of the brush assembly mounting seat 306. The gear pair includes a driving gear 315 arranged inside the second mounting seat and a driven gear 316 installed inside the first mounting seat. The driving gear 315 and the driven gear 316 are engaged with each other, wherein the driving gear 315 is driven to rotate by the first motor 314, and the driven gear 316 is connected to the inner brush swing plate 312 through the cooperation of the connecting shaft, and drives the inner brush swing plate 312 to rotate.

[0043] A first arcuate groove 317 is further provided on the inner brush swing plate 312 for allowing the weld brush 331 to pass through and move. The first arcuate groove 317 is provided to avoid the weld brush 331. Since the weld brush 331 is directly installed in the weld brush mounting hole 307, and the weld brush mounting hole 307 is a fixed mounting hole, that is, the position of the weld brush 331 installed in the weld brush mounting hole 307 remains unchanged. When spraying later, the brush swing plate needs to call different brushes by swinging. Therefore, in order to avoid the weld brush 331 affecting the calling of the inner brush, the first arcuate groove 317 is provided on the inner brush swing plate 312 for avoidance, so as to ensure that the inner brush swing plate 312 rotates smoothly without mutual interference caused by the weld brush 331.

[0044] like Figure 8 As shown in the schematic diagram, the outer pen holder assembly includes an outer brush swing plate 322 and an outer array brush 321 installed on the outer brush swing plate 322. There are several outer array brushes 321 distributed in an arc shape on the outer brush swing plate 322. At the same time, the outer brush swing plate 322 is also provided with through holes to allow each outer array brush 321 to pass through and move up and down. A second return spring 323 is installed on the outer wall of the outer array brush 321.

[0045] The outer brush swing plate 322 is installed below the inner brush swing plate 312, and a gap is left between the outer brush swing plate 322 and the inner brush swing plate 312. The outer brush swing plate 322 is driven to rotate by a second motor 324 installed on the brush assembly mounting seat 306. The second motor 324 is installed on the first mounting seat of the brush assembly mounting seat 306. The output shaft of the second motor 324 is connected to the outer brush swing plate 322 through a connecting shaft, and drives the outer brush swing plate 322 to rotate. The outer brush swing plate 322 is provided with a second arc groove 325 for allowing the weld brush 331 to pass through and move, and a third arc groove 326 for allowing the inner array brush 321 to pass through and move. The design of the second arc groove 325 and the third arc groove 326 is also to avoid the weld brush 331 and the inner array brush 321 to ensure the smooth rotation of the outer brush swing plate 322 and avoid interference with the weld brush 331 and the inner array brush 321.

[0046] The brush selection component includes a pen fork 341, and a groove for accommodating the inner array brush 311 and the outer array brush 321 is opened on one side of the pen fork 341, so that the entire pen fork 341 is U-shaped. The pen fork 341 is driven up and down by a pen lifting cylinder 342, and the pen lifting cylinder is installed on a reciprocating slide 343. The reciprocating slide 343 is a flat plate structure. The two sides of the reciprocating slide 343 are respectively embedded in the two grooves 305 that constitute the pen reciprocating slide, and the reciprocating slide 343 is driven by a pen reciprocating cylinder 344 installed on the upper frame 301 to move back and forth along the pen reciprocating slide.

[0047] The weld brush 331, the inner array brush 311 and the outer array brush 321 have the same structure. Figure 9The weld brush 331 shown in the figure is taken as an example, which includes a brush body 351, a hose is connected to the top of the brush body 351, and a hose connector 352 connected to the hose is also provided at the top of the brush body 351. A limiting nut 353 is connected to the upper and lower sides of the brush body 351, and the limiting nut 353 on the upper side is located above the lower frame 302, and the limiting nut 353 on the lower side is located below the outer brush swing plate 322. The brush body 351 is used to pass through the weld brush mounting hole 307 or the first arc groove 317 or the second arc groove 325 or the third arc groove 326, and the limiting nut 353 The diameters of the first and second arc grooves 317, 325 and 326 are larger than the sizes of the weld brush mounting hole 307, the first arc groove 317, the second arc groove 325 and the third arc groove 326, so as to limit the up and down movement of the brush body 351. The first return spring 313 and the second return spring 323 are mounted on the outer wall of the brush body 351 and are located between the two limiting nuts 353. The upper ends of the first return spring 313 and the second return spring 323 both rest on the bottom surface of the limiting nut 353 on the upper side, and the lower end of the first return spring 313 rests on the top of the inner brush swing plate 312, and the lower end of the second return spring 323 rests on the top of the outer brush swing plate 322. The design of the weld brush 331, the inner array brush 311 and the outer array brush 321 structures, through the cooperation of the upper and lower limit nuts 353, serves the purpose of hard limit protection for the up and down lifting stroke of the brush, thereby preventing the brush from exceeding the stroke limit and causing the brush to detach, thereby affecting the automatic drawing of the line marking machine and the smooth operation of pen changing.

[0048] The weld brush 331 is different from the inner array brush 311 and the outer array brush 321 in that the weld brush 331 is directly fixed in the weld brush mounting hole 307, so there is no need to install a reset spring. When the weld brush 331 is fixed, a locking nut 354 is required to be added to the upper side of the brush body 351 of the weld brush 331 to fix the weld brush 331. The locking nut 354 is located above the lower frame plate 302, and the bottom surface of the upper limit nut 353 and the top surface of the locking nut 354 are respectively fitted with the upper and lower sides of the lower frame plate 302. The weld brush 331 is fixed to the lower frame plate 302 through the cooperation of the locking nut 354 and the upper limit nut 353.

[0049] The brush lift assembly includes an inverted brush lift cylinder 221. The bottom end of the piston rod of the brush lift cylinder 221 is connected to the pen holder mounting base 308. The bottom end of the cylinder body of the brush lift cylinder 221 is connected to a guide sleeve mounting plate 222. The guide sleeve mounting plate 222 has a guide hole through which the pen assembly mounting frame lifting guide rod 309 passes and moves up and down. At the same time, a lifting guide sleeve 223 is also installed in the guide hole of the guide sleeve mounting plate 222 to cooperate with the pen assembly mounting frame lifting guide rod 309. The cooperation of the guide sleeve mounting plate 222, the lifting guide sleeve 223, and the pen assembly mounting frame lifting guide rod 309 allows the pen assembly mounting frame 3 to be guided when the brush lift cylinder 221 drives the pen assembly mounting frame 3 to move up and down, ensuring the stable lifting of the pen assembly mounting frame 3 and preventing the pen assembly mounting frame 3 from deviating.

[0050] The brush rotating assembly includes a brush rotating swing plate 231 arranged below the brush traveling frame 211. The top end of the brush lifting cylinder 221 is connected to the brush rotating swing plate 231 and rotates with the rotation of the brush rotating swing plate 231. The brush rotating swing plate 231 is driven by the rotating motor 232 installed on the brush traveling frame 211 and the gear pair 233 to rotate, thereby driving the brush lifting cylinder 221 and the pen group mounting frame 3 to rotate as a whole, thereby ensuring that the visual recognition line group always keeps the welding path close to the weld.

[0051] The brush ink supply assembly includes an ink bottle 241 installed on the brush traveling frame 211 and a control valve group 242. There are several ink bottles 241, which are distributed in parallel on the brush traveling frame 211, and each ink bottle 241 is connected to the feed side of the control valve group 242 through the cooperation of a hose. The discharge side of the control valve group 242 is connected to the hose connector 352 on the weld brush 331, the inner array brush 311 and the outer array brush 321 through the cooperation of a hose, thereby supplying the weld brush 331, the inner array brush 311 and the outer array brush 321.

[0052] A laser edge-finding assembly is also provided on the self-propelled frame 20, and the laser edge-finding assembly includes a laser edge-finding device 251 mounted on the pen assembly mounting frame 3. The laser edge-finding device 251 is used to detect the position and contour of the baler plate 13 conveyed on the conveyor roller 12, providing a basis for subsequent automatic inkjet printing based on the position of the baler plate 13. When controlling, the marking machine also needs to be equipped with a controller. The laser edge-finding device 251 detects the baler plate 13 and transmits the detection result to the controller. The controller then controls the operation of multiple components of the marking machine, such as the self-propelled frame 20, the brush traveling frame 211, and the brush lifting cylinder 221, thereby realizing automatic inkjet printing on the surface of the baler plate 13.

[0053] When performing inkjet printing, first, the inner brush swing plate 312 is driven to rotate by the first motor 314. When the required inner array brush 311 moves to the front of the pen picking fork 341, the first motor 314 stops, and then the outer brush swing plate 322 is driven to rotate by the second motor 324. When the required outer array brush 321 moves to the front of the pen picking fork 341, the second motor 324 stops, and then the pen picking reciprocating cylinder 344 drives the reciprocating slide rail 343 to move, pushing the pen picking fork 341 outward, so that the fork groove of the pen picking fork 341 is inserted into the neck and shoulder part of the inner array brush 311 and the outer array brush 321 at the drawing position, that is, the position of the upper end surface of the limit nut 353 on the upper side, and then the pen picking lifting air cylinder 344 is used to lift the pen picking fork 341. The cylinder 342 drives the pen fork 341 to move downward, and the pen fork 341 presses down the limit nut 353 on the upper side, thereby driving the inner array brush 311 and the outer array brush 321 to move downward synchronously, so that the positions of the inner array brush 311, the outer array brush 321 and the weld brush 331 are consistent, and enter the line drawing standby state. Then, the entire pen changing device moves and draws lines under the drive of the line drawing machine. After the line drawing is completed, the pen lifting cylinder 342 drives the pen fork to move upward, and the inner array brush 311 and the outer array brush 321 are reset under the drive of the first reset spring 313 and the second reset spring 323. Then the pen reciprocating cylinder 344 drives the pen fork 341 to retract inward, and enters the next round of pen selection and line drawing. As the weld path changes, the rotation of the brush rotating assembly causes the weld brush and the weld position to deviate. The travel motors in the first and second directions perform position compensation in the first and second directions based on the rotation amount of the brush rotating assembly, thereby ensuring the correctness of the drawing position.
