[0042] It should be noted that the elastic telescopic member is composed of an existing telescopic rod and a spring.

[0043] In this embodiment, the cooperation between the first conveying unit 211 and the clamping unit 212 can automatically clamp and fix identification plates of different specifications, has strong adaptability, and can drive the processed identification plates to move between different workstations.

[0044] In detail, the first stepper motor drives the first threaded rod 2111 to move the frame 2121 to the specified position through the threaded block 2112, and then the welded sign is manually placed flat in the frame 2121, so that the sign descends along the first extension rod 2123 and the second extension rod 2126 to the bottom door 221, and the first clamping plate 2122 and the second clamping plate 2125 are automatically clamped to the four sides of the sign under the drive of the elastic telescopic parts.

[0045] Further, if Figure 3-Figure 7 As shown, the bottom support assembly 22 includes two groups of bottom doors 221 symmetrically hingedly arranged at the bottom of the frame 2121, a first sliding groove opened on the bottom door 221, a first slider slidingly arranged on the first sliding groove, two groups of shafts 222 symmetrically arranged on both sides of the end of the frame 2121 through L-shaped ear plates, a turntable 223 arranged at one end of the shaft 222, a transmission rod 224 arranged on the turntable 223 and its end hinged to the first slider, a first bevel gear 225 arranged on the shaft 222, a first gear 226 rotatably arranged on the L-shaped ear plate, and a second bevel gear 227 coaxially arranged on the first gear 226 and used to drive the first bevel gear 225.

[0046] In this embodiment, the bottom support assembly 22 and the weld processing mechanism 3 cooperate to support the flat identification plate, making it convenient for the clamping unit 212 to clamp the four sides of the identification plate, and can also be automatically opened to facilitate processing of the lower surface of the identification plate.

[0047] In detail, the welded sign is manually placed flat in the frame 2121, so that the sign descends to the bottom door 221 along the first extension rod 2123 and the second extension rod 2126. The bottom door 221 supports the sign, making it convenient for the clamping unit 212 to clamp the four sides of the sign. Then, during the process of grinding the weld of the sign by the weld processing mechanism 3, the second rack 354 drives the first gear 226 to rotate with the second bevel gear 227, so that the second bevel gear 227 rotates the specified angle with the turntable 223 through the first bevel gear 225 and the shaft 222, so that the turntable 223 drives the two bottom doors 221 to rotate downward and open through the transmission rod 224, the first slider, and the first slide groove, so that the lower surface of the sign is exposed, which is convenient for processing the lower surface of the sign.

[0048] Further, if Figure 4-11 As shown, the weld processing mechanism 3 includes a connecting assembly 31 provided on the U-shaped frame 4121, and a grinding assembly 32, a second puttying assembly 33, a second smoothing assembly 34 and a second polishing assembly 35 installed on the connecting assembly 31; The connecting assembly 31 includes a string rod 311 that passes through and is slidably arranged on the U-shaped frame 4121, a fourth elastic member arranged between one end of the string rod 311 and the U-shaped frame 4121, an L-shaped support plate 312 arranged at the other end of the string rod 311, a second sliding groove provided on the L-shaped support plate 312, a strip plate 313 that is lifted and slidably arranged on the second sliding groove, a fifth elastic member provided between the strip plate 313 and the end of the second sliding groove, two groups of third sliding grooves 314 respectively provided on the strip plate 313 and the L-shaped support plate 312, a third slider slidably arranged on the three sliding grooves, and two groups of inclined rods 315 respectively hingedly provided on the third slider and whose ends are hingedly connected to each other; The grinding assembly 32 includes a through shaft 321 that passes through and is rotatably disposed on the strip plate 313, a grinding disc 322 disposed on the through shaft 321, a third bevel gear 323 disposed on the through shaft 321, an outer frame 324 disposed on the strip plate 313, a second gear 325 rotatably disposed on the outer frame 324 and meshing with the first rack 2124, and a fourth bevel gear 326 disposed on the outer frame 324 and configured to drive the third bevel gear 323, which rotates synchronously with the second gear 325 via a belt and pulley transmission.

[0049] It is worth mentioning that after the two mutually hinged inclined rods 315 are resisted by the edge of the end of the sign, they move along the third slide groove 314 on the strip 313 and the L-shaped support plate 312, and rotate in a mutually hinged manner, pulling the strip 313 closer to the L-shaped support plate 312, that is, pulling the grinding disc 322 tightly against the weld on the upper surface of the sign to ensure that the weld is cleanly processed.

[0050] It should be noted that the cleaning plate 336 can clean the debris on the upper surface of the sign. At the same time, the cleaning plate 336 can be raised and lowered when passing through the concave and convex parts of the upper surface of the sign, which can effectively clean the debris on the upper surface of the sign.

[0051] In this embodiment, by cooperating with the weld processing mechanism 3 and the second conveying unit 411, the weld can be ground, cleaned, puttyed and polished in sequence to grind off the burrs on the weld and ensure that the weld is flat and flush with the plate surface of the sign.

[0052] In detail, after the clamping unit 212 clamps the four sides of the sign, the second conveying unit 411 drives the L-shaped support plate 312 and the strip plate 313 to move forward through the string rod 311, so that the upper edge of the end of the sign passes through the gap between the strip plate 313 and the L-shaped support plate 312, and the upper edge of the end of the sign presses against the inclined rod 315 and moves along the third sliding groove 314, so that the inclined rod 315 drives the strip plate 313 to move closer to the L-shaped support plate 312, that is, pulls the grinding disc 322 to closely adhere to the weld on the upper surface of the sign, and the strip plate 313 and the L-shaped support plate 312 continue to move forward, and the first rack 2124 of the clamping unit 212 drives the second gear 325 to rotate with the fourth bevel gear 326, and the fourth bevel gear 326 rotates through the third bevel gear 323. The through shaft 321 is driven to rotate, and the through shaft 321 rotates with the grinding disk 322 to grind the burrs on the weld. The cleaning plate 336 cleans the waste chips on the surface of the sign in turn. The through shaft 321 intermittently squeezes the third air bag 332 through the eccentric wheel 333, so that the second nozzle 331 intermittently drips liquid putty along the weld. The second scraper plate 341 smoothes the putty along the weld. The air dryer 353 first quickly dries the smoothed putty. The through shaft 321 drives the second hanging shaft 351 to rotate through the transmission method of the belt and pulley, so that the second hanging shaft 351 drives the second polishing disk 352 to polish the putty at the weld until the weld on the upper surface of the sign is processed. During the process, the second rack 354 drives the first gear 226 to rotate and open the two bottom doors 221 downward.

[0056] In this embodiment, by cooperating with the identification component 41 and the knocking component 42, on the one hand, the concave and convex points on the upper and lower surfaces of the signboard can be accurately identified, and the concave and convex points on the upper and lower surfaces of the signboard can be automatically knocked flat, avoiding the uneven surface of the signboard and affecting the painting effect, thereby improving the aesthetics of the signboard; on the other hand, the concave and convex parts of the upper and lower surfaces of the signboard after knocking can be leveled with putty, and the upper and lower surfaces of the signboard can be smooth after polishing, which is conducive to the painting work of the signboard.

[0057] In detail, after the upper edge of the end of the sign moves relatively to the end in the gap between the strip plate 313 and the L-shaped support plate 312, the welding seam processing work is completed, and the second stepper motor drives the second threaded rod 4111 to continue to move forward with the U-shaped frame 4121 through the threaded plate 4112, and the strip plate 313 and the L-shaped support plate 312 no longer move forward, so that the U-shaped frame 4121 continues to move forward along the string rod 311, so that the detection plate 4122 advances to the inner wall and outer wall of the upper and lower surfaces of the sign respectively, and the insertion rod 435 first identifies the concave and convex points on the outer walls of the upper and lower surfaces of the sign. When the insertion rod 435 detects the concave points on the outer walls of the upper and lower surfaces of the sign, the insertion rod 435 descends with the extrusion plate 436, so that the extrusion plate 436 presses the inner wall of the first airbag 432 into the airbag 432. The liquid putty is squeezed into the temporary storage box 434 of the first nozzle 431 for buffering. When the insertion rod 435 detects the convex points on the outer walls of the upper and lower surfaces of the sign, the insertion rod 435 rises with the squeezing plate 436, so that the squeezing plate 436 squeezes the liquid putty in the second air bag 433 into the temporary storage box 434 of the first nozzle 431 for buffering. The deeper the concave point, the more the insertion rod 435 descends with the squeezing plate 436, and the more liquid putty is squeezed from the first air bag 432 to the temporary storage box 434 of the first nozzle 431. According to the different depths of the detected concave points, the amount of liquid putty from the first air bag 432 to the temporary storage box 434 of the first nozzle 431 is controlled, and the amount of liquid putty used is reasonably controlled. Then, after the identification rod 4123 detects the protrusions on the sign, The convex points on the inner and outer walls of the lower two surfaces, when the identification rod 4123 identifies the convex points on the outer wall of the upper surface of the identification plate, the identification rod 4123 rises through the rod cap 4124 against the magnetic plate 422, and the magnetic plate 422 rises synchronously with the hammer of the suspension rod 423. After the identification rod 4123 moves forward and disengages from the convex points, the identification rod 4123 drops and resets, so that the rod cap 4124 of the identification rod 4123 is separated from the first button switch 425 of the magnetic plate 422. After the first button switch 425 loses the squeezing force, the control strip electromagnet 424 is energized and magnetized, so that the strip electromagnet 424 magnetically attracts the magnetic plate 422, that is, when the identification rod 4123 drops, the magnetic plate 422 does not drop at the same time, but drops at intervals. When the identification rod 4123 drops and resets to press the second After the button switch 426 is turned on, the second button switch 426 controls the strip-shaped electromagnet 424 to be de-energized and without magnetism, and the magnetic plate 422 descends with the hammer of the suspension rod 423. That is, after the identification rod 4123 descends and resets, the hammer of the suspension rod 423 descends again to ensure that the hammer can strike the convex point on the outer wall of the upper surface of the identification plate. The convex point is repeatedly struck by multiple groups of striking assemblies 42 in turn until it is flat. Then, when the first nozzle 431 advances to the convex point position, the solenoid valve controls several groups of first nozzles 431 to open at the same time. Only the first nozzle 431 at the convex point position can spray liquid putty because there is liquid putty in the temporary storage box 434 on the first nozzle 431. Then, the first scraper plate 441 smoothes the putty at the convex point position. After the putty is quickly air-dried,The driving member drives the first hanging shaft 451 to carry the first polishing disc 452 to polish the putty at the convex position until the outer walls of the upper and lower surfaces of the sign are leveled in turn.

[0058] Further, if Figure 2 and Figure 16-17 As shown, the cleaning mechanism 5 includes a third rack 51 provided on the frame 1 and used to drive the first gear 226, a washing component 52 provided on the frame 1 and used to wash the upper and lower surfaces of the sign, a drying component 53 provided on the frame 1 and used to dry the upper and lower surfaces of the sign, and a laminating component 54 provided on the frame 1 and used to cover the upper and lower surfaces of the sign.

[0060] In this embodiment, by cooperating with the cleaning mechanism 5 and the first conveying unit 211, on the one hand, the upper and lower surfaces of the sign can be cleaned, and the putty powder generated by the polishing work can be cleaned, thereby ensuring the cleanliness of the upper and lower surfaces of the sign, which is beneficial to the painting work of the sign and improves the adhesion of the paint surface; on the other hand, the upper and lower surfaces of the sign can be dried after cleaning, and a layer of film can be coated on the upper and lower surfaces of the sign to prevent the upper and lower surfaces of the sign from being damaged or adhered to dust during transportation.

[0061] In detail, the first conveying unit 211 drives the clamping unit 212 to carry the processed identification plate to the position of the cleaning mechanism 5. During the movement of the clamping unit 212, the third rack 51 drives the first gear 226 to drive the two bottom doors 221 to rotate downward again and open, exposing the lower surface of the identification plate. The identification plate continues to move forward, and the flushing component 52 sprays water to wash away the dust on the upper and lower surfaces of the identification plate. The drying component 53 dries the upper and lower surfaces of the identification plate. The film pressing roller 542 attaches the film on the film roller 541 to the upper and lower surfaces of the identification plate. The hydraulic component drives the film cutting knife 543 to cut the film in time. Finally, the processed identification plate is manually taken out.
