When the word label is placed on the first suction cup, the moving rail moves the first suction cup to the center of the first conveying belt, and then the mounting block drives the first suction cup to rotate by 180°, and then the telescopic rod stably places the word label on the first conveying belt after the word label on the first suction cup is close to the surface of the first conveying belt.
[0007] As a preferred technical solution, the glue attaching mechanism comprises a mounting rod, a second suction cup, a sliding frame, a first lifting rod, a third suction cup, a guide column group and a third mechanical arm.

A guide column group is installed on the second conveying belt, and the guide column group does not contact the second conveying belt. When the production line is operated, the third mechanical arm takes out the automobile word label with one side of the double-sided adhesive tape from the word label box through the second suction cup, then the third mechanical arm places the automobile word label above the third suction cup to adsorb it, then the second suction cup rotates along the mounting rod to tear off the double-sided adhesive tape protective film from the automobile word label, and finally the third suction cup is placed on the guide column group and slides onto the second conveying belt through the first lifting rod.
[0008] As a preferred technical solution, one side of the first conveying belt is provided with a word label adjusting assembly, the word label adjusting assembly detects and adjusts the angle of the word label on the first conveying belt, and the bottom of the word label box is provided with a protective film collecting assembly, which collects and compresses the torn double-sided adhesive tape protective film.
[0009] As a preferred technical solution, the word label adjusting assembly comprises an electric sliding rail, a second lifting rod, a hydraulic push rod, an L-shaped support plate, a detection camera, a rotating shaft, a mounting frame, an arc-shaped sliding groove, a driving ring, a driving groove, a gear ring, a driving motor, a driving wheel, an upper ring cover, a connecting column, a lower ring cover, a hollow shaft, an arc-shaped clamp plate and a gear. An electric slide rail is installed on the side of the first conveyor belt near the first robotic arm. A second lifting rod is slidably mounted on the electric slide rail. A hydraulic push rod is mounted on the second lifting rod. An L-shaped support plate is mounted on the hydraulic push rod. A detection camera is mounted on the L-shaped support plate. A rotating shaft is rotatably mounted on the L-shaped support plate. A mounting bracket is mounted at the bottom of the rotating shaft. An arc-shaped groove is formed inside the mounting bracket. A drive ring is rotatably mounted in the arc-shaped groove. A drive groove is formed on the drive ring. Two chambers are symmetrically formed inside the mounting bracket. A drive wheel is rotatably mounted in each of the two chambers. A drive motor is mounted on the mounting bracket. The output shaft of the drive motor is connected to the rotation shaft of one of the drive wheels. An upper ring cover is installed at the bottom of the mounting bracket. Multiple... The connecting column has a lower ring cover installed at its bottom. Multiple connecting columns are fitted with hollow shafts, and multiple hollow shafts have arc-shaped clamps installed at their bottoms, with each arc-shaped clamp being evenly spaced at a certain angle. Gears are installed at the top of each hollow shaft. A gear ring is installed at the bottom of the drive ring, and the gear ring meshes with the gears. When the label is placed on the first conveyor belt, an electric slide rail drives a detection camera to slide along the first conveyor belt. When an error in the position or orientation of the lettering is detected, a second lifting rod and a hydraulic push rod adjust the position of the mounting frame, placing the label at the center of the drive ring. Then, a drive motor rotates the drive ring, which in turn drives the lower gear ring to drive the arc-shaped clamps on the hollow shafts to converge and clamp the label. Finally, a rotating shaft drives the mounting frame to rotate at a suitable angle, lowering the label and thus completing the angle adjustment of the lettering.
[0010] As a preferred technical solution, the detection camera is electrically connected to the drive motor, and the center of the lens of the detection camera is on the same straight line as the center of the drive ring.
[0011] As a preferred technical solution, the protective film collection assembly includes a mounting platform, a slide bar, a first arc-shaped block, an inner cavity, a negative pressure unit, a pressure plate, and an arc-shaped hole; Multiple nameplate boxes are equipped with mounting platforms at their bottoms. Each mounting platform has an inner cavity. A negative pressure machine is installed on one side of the mounting platform and connected to the inner cavity via a pipe. A pressure plate is slidably installed inside the inner cavity. Both the pressure plate and the top of the mounting platform have arc-shaped holes. A sliding rod is slidably installed at each arc-shaped hole on the top of the mounting platform, and a first arc-shaped block is installed on the sliding rod. When the production line is operating, a third robotic arm moves the double-sided adhesive protective film above the mounting platform and then lowers it. Under the suction force generated by the negative pressure machine, the protective film is sucked into the inner cavity through the arc-shaped holes. Because the surface of the protective film that adheres to the double-sided adhesive is too smooth, it will be difficult to clean after falling to the ground. Collecting the protective film can effectively avoid the problem of cleaning difficulties.
[0012] As a preferred technical solution, it also includes a center hole, a spiral groove, a ball bearing, a spring, a rotating column, a turntable, a second arc block, a hydraulic cylinder, a lever, and a slide rail; The pressure plate has a central hole at its bottom, and a rotating column is rotatably installed in the central hole. Spiral grooves are formed at the contact points between the central hole and the rotating column, and ball bearings are rolled within the spiral grooves. A turntable is installed at the bottom of the rotating column, and a second arc-shaped block and a lever are mounted on the turntable. A slide rail is formed on the side wall of the inner cavity, and the lever is engaged within the slide rail. A hydraulic cylinder is installed on the top of the mounting platform, and the output end of the hydraulic cylinder passes through the top of the mounting platform and connects to the pressure plate. When the protective film in the inner cavity is full, the hydraulic cylinder presses down on the pressure plate to compress the protective film, making it into a disc shape to save space. During the descent of the pressure plate, the lever slides along the slide rail, causing the turntable to rotate. This causes the second arc-shaped block to slide along the wedge-shaped groove into the arc-shaped hole on the pressure plate to complete the sealing, thus preventing leakage of the protective film when the pressure plate compresses the inner cavity. Simultaneously, the pressure plate moves away from its initial position, and the lever loses its support. Under the action of gravity, the first arc-shaped block seals the arc-shaped hole on the mounting platform, preventing any protective film from entering the inner cavity during the compression process.
[0013] As a preferred technical solution, a wedge-shaped groove is provided at the arc-shaped hole at the bottom of the pressure plate, and the wedge-shaped groove smoothly connects into the arc-shaped hole. The top of the second arc-shaped block is a wedge-shaped surface and cooperates with the wedge-shaped groove.
[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This application uses a first robotic arm to drive suction blocks to adsorb the cut letterplates. Multiple suction blocks slide along a slide rail to adjust the distance to accommodate letterplates of different shapes. After the letterplates are placed on a flipping suction mechanism, the flipping suction mechanism places the letterplates onto a first conveyor belt. At the same time, an adhesive applicator takes the car letterplates out of the letterplate box and peels off the double-sided adhesive protective film on the car letterplates. Then, the car letterplates with the protective film removed are placed on a second conveyor belt. At this time, the lifting suction cups on the second robotic arm adsorb and transfer the letterplates from the first conveyor belt to the double-sided adhesive surface of the car letterplates. After the adhesion is completed, the second robotic arm places the adhered car letterplates onto a third conveyor belt. Finally, the packaging machine packages them, realizing fully automated production of car letterplates.
[0015] 2. In this application, the detection camera is driven to slide along the first conveyor belt by an electric slide rail. When the position and orientation of the font are detected to be different, the second lifting rod and the hydraulic push rod adjust the position of the mounting frame so that the font is at the center of the drive ring. Then, the drive ring is rotated by the drive motor. The drive ring drives the lower gear ring to drive the arc-shaped clamp on the hollow shaft to converge and clamp the font. Finally, the rotating shaft drives the mounting frame to rotate at a suitable angle to put the font down, thereby completing the font angle adjustment.
[0016] 3. In this application, the double-sided adhesive protective film is moved to the top of the mounting platform by the third robotic arm and then lowered. Under the suction force generated by the negative pressure machine, the protective film is sucked into the inner cavity through the arc-shaped hole. The protective film is squeezed by the pressure plate of the hydraulic cylinder, making the protective film into a disc shape to save space. During the descent of the pressure plate, the lever slides along the slide rail and drives the turntable to rotate, so that the second arc-shaped block slides into the arc-shaped hole on the pressure plate along the wedge-shaped slide groove to complete the sealing. This prevents the protective film from leaking out when the pressure plate squeezes the inner cavity. At the same time, the pressure plate leaves the initial position, and the slide rod loses its support. Under the action of gravity, the first arc-shaped block seals the arc-shaped hole on the mounting platform, preventing the protective film from entering the inner cavity during the squeezing process.

A packaging machine 110 is mounted above the third conveyor belt 12. When the production line is in operation, the first robotic arm 13 drives the suction block 15 to adsorb the cut letterplates. Then, multiple suction blocks 15 slide on the slide rail 14 to adjust the distance to accommodate letterplates of different shapes. After the letterplate is placed on the flipping suction mechanism 16, the flipping suction mechanism 16 places the letterplate onto the first conveyor belt 1. At the same time, the adhesive applicator 19 takes the car letterplate out of the letterplate box 17 and peels off the double-sided adhesive protective film on the car letterplate. Then, the car letterplate with the protective film removed is placed on the second conveyor belt 11. At this time, the lifting suction cup 181 on the second robotic arm 18 adsorbs and transfers the letterplate on the first conveyor belt 1 to the double-sided adhesive surface of the car letterplate. After the adhesion is completed, the second robotic arm 18 places the adhered car letterplate onto the third conveyor belt 12. Finally, it is packaged by the packaging machine 110, realizing the fully automatic production of car letterplates.
[0021] The flipping adsorption mechanism 16 includes a support plate 161, a moving rail 162, a mounting block 163, a telescopic rod 164, and a first suction cup 165; Two support plates 161 are symmetrically installed on the side of the first conveyor belt 1 away from the first robotic arm 13.

A guide post assembly 196 is installed on the second conveyor belt 11. Without contacting the second conveyor belt 11, when the production line is operating, the third robotic arm 197 uses the second suction cup 192 to remove the car lettering with the double-sided adhesive side from the lettering box 17. Then, the third robotic arm 197 places the car lettering directly above the third suction cup 195 to be attracted. Then, the second suction cup 192 rotates along the mounting rod 191 to peel off the double-sided adhesive protective film from the car lettering. Finally, the third suction cup 195 is adjusted by the first lifting rod 194 to be placed on the guide column assembly 196 and slide onto the second conveyor belt 11.

[0024] like Figures 1-4 and Figure 8 As shown, the character adjustment assembly 2 includes an electric slide rail 21, a second lifting rod 22, a hydraulic push rod 23, an L-shaped support plate 24, a detection camera 25, a rotating shaft 26, a mounting bracket 27, an arc-shaped slide groove 271, a drive ring 28, a drive groove 281, a gear ring 282, a drive motor 29, a drive wheel 291, an upper ring cover 210, a connecting column 211, a lower ring cover 213, a hollow shaft 214, an arc-shaped clamping plate 215, and a gear 216. An electric slide rail 21 is installed on the side of the first conveyor belt 1 near the first robotic arm 13. A second lifting rod 22 is slidably mounted on the electric slide rail 21. A hydraulic push rod 23 is mounted on the second lifting rod 22. An L-shaped support plate 24 is mounted on the hydraulic push rod 23. A detection camera 25 is mounted on the L-shaped support plate 24. A rotating shaft 26 is rotatably mounted on the L-shaped support plate 24. A mounting frame 27 is mounted at the bottom of the rotating shaft 26. An arc-shaped slide groove 271 is opened inside the mounting frame 27. A drive ring 28 is rotatably mounted inside the arc-shaped slide groove 271. A drive groove 281 is opened on the drive ring 28. Two chambers are symmetrically opened inside the mounting frame 27. A drive wheel 291 is rotatably mounted in each of the two chambers. A drive motor 29 is mounted on the mounting frame 27. The output shaft of the drive motor 29 is connected to the rotation shaft of one of the drive wheels 291. An upper ring cover 210 is installed at the bottom of the mounting frame 27. Multiple connecting posts 211 are installed at the bottom of the upper ring cover 210. The device has a lower ring cover 213, and hollow shafts 214 are fitted onto multiple connecting posts 211.

A gear ring 282 is installed at the bottom of the drive ring 28, and the gear ring 282 meshes with the gears 216. When the label is placed on the first conveyor belt 1, the detection camera 25 is driven to slide along the first conveyor belt 1 via the electric slide rail 21. When the movement detects an error in the position and orientation of the font, the second lifting rod 22 and the hydraulic push rod 23 adjust the position of the mounting bracket 27 so that the font is at the center of the drive ring 28. Then, the drive motor 29 rotates the drive ring 28. The drive ring 28 drives the lower gear ring 282 to drive the drive gear 216 to drive the arc-shaped clamping plate 215 on the hollow shaft 214 to converge and clamp the font. Finally, the rotating shaft 26 drives the mounting bracket 27 to rotate at a suitable angle to lower the font, thus completing the font angle adjustment.
[0025] The detection camera 25 is electrically connected to the drive motor 29, and the center of the lens of the detection camera 25 is on the same straight line as the center of the drive ring 28.
[0026] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the protective film collection assembly 3 includes a mounting platform 31, a slide bar 3101, a first arc-shaped block 3102, an inner cavity 32, a negative pressure machine 33, a pressure plate 34, and an arc-shaped hole 35; Multiple nameplate boxes 17 are equipped with mounting platforms 31 at their bottoms. The mounting platform 31 has an inner cavity 32. A negative pressure machine 33 is installed on one side of the mounting platform 31. The negative pressure machine 33 is connected to the inner cavity 32 through a pipe. A pressure plate 34 is slidably installed in the inner cavity 32. Both the pressure plate 34 and the top of the mounting platform 31 have arc-shaped holes 35. A slide rod 3101 is slidably installed at each arc-shaped hole 35 on the top of the mounting platform 31. A first arc-shaped block 3102 is installed on the slide rod 3101. When the production line is operating, the third robotic arm 197 moves the double-sided adhesive protective film above the mounting platform 31 and then lowers it. Under the suction force generated by the negative pressure machine 33, the protective film is sucked into the inner cavity 32 through the arc-shaped holes 35. Since the protective film and the double-sided adhesive are too smooth, it will be difficult to clean after falling to the ground. Collecting the protective film can effectively avoid the problem of cleaning difficulties.
[0027] It also includes a center hole 36, a spiral groove 37, a ball bearing 38, a spring 39, a rotating column 311, a turntable 312, a second arc block 313, a hydraulic cylinder 314, a lever 315, and a slide rail 316; A central hole 36 is provided at the bottom of the pressure plate 34. A rotating column 311 is rotatably installed in the central hole 36. A spiral groove 37 is provided at the contact point between the central hole 36 and the rotating column 311. A ball bearing 38 is rolled in the spiral groove 37. A turntable 312 is installed at the bottom of the rotating column 311. A second arc-shaped block 313 is installed on the turntable 312. A lever 315 is installed on the turntable 312. A slide rail 316 is provided on the side wall of the inner cavity 32. The lever 315 is locked in the slide rail 316. A hydraulic cylinder 314 is installed on the top of the mounting platform 31. The output end of the hydraulic cylinder 314 passes through the top of the mounting platform 31 and is connected to the pressure plate 34. When the inner cavity 32... After the protective film is full, the hydraulic cylinder 314 presses down the pressure plate 34 to squeeze the protective film, making it into a disc shape to save space. During the descent of the pressure plate 34, the lever 315 slides along the slide rail 316, driving the turntable 312 to rotate, causing the second arc-shaped block 313 to slide along the wedge-shaped slide groove 310 into the arc-shaped hole 35 on the pressure plate 34 to complete the sealing. This prevents the protective film from leaking out when the pressure plate 34 squeezes the inner cavity 32. At the same time, the pressure plate 34 leaves the initial position, and the slide rod 3101 loses its support. Under the action of gravity, the first arc-shaped block 3102 seals the arc-shaped hole 35 on the mounting platform 31, preventing the protective film from entering the inner cavity 32 during the squeezing process.
[0028] A wedge-shaped groove 310 is provided at the arc-shaped hole 35 at the bottom of the pressure plate 34, and the wedge-shaped groove 310 smoothly enters the arc-shaped hole 35. The top of the second arc-shaped block 313 is a wedge-shaped surface and cooperates with the wedge-shaped groove 310.
[0029] Working principle of the invention: When the production line is in operation, the first robotic arm 13 drives the suction block 15 to adsorb the cut letterplates. Then, multiple suction blocks 15 slide on the slide rail 14 to adjust the distance to accommodate letterplates of different shapes. After the letterplate is placed on the flipping suction mechanism 16, the flipping suction mechanism 16 places the letterplate onto the first conveyor belt 1. At the same time, the adhesive applicator 19 takes the car letterplate out of the letterplate box 17 and peels off the double-sided adhesive protective film on the car letterplate. Then, the car letterplate with the protective film removed is placed on the second conveyor belt 11. At this time, the lifting suction cup 181 on the second robotic arm 18 adsorbs and transfers the letterplate on the first conveyor belt 1 to the double-sided adhesive surface of the car letterplate. After the adhesion is completed, the second robotic arm 18 places the adhered car letterplate onto the third conveyor belt 12. Finally, it is packaged by the packaging machine 110, realizing the fully automatic production of car letterplates.
[0030] After the label is placed on the first suction cup 165, the moving rail 162 moves the first suction cup 165 to the center of the first conveyor belt 1, and then the mounting block 163 drives the first suction cup 165 to rotate 180°. Then the telescopic rod 164 pushes the label on the first suction cup 165 close to the surface of the first conveyor belt 1 and then puts it down smoothly.
[0031] When the production line is in operation, the third robotic arm 197 takes the car lettering with the double-sided adhesive side attached from the lettering box 17 using the second suction cup 192. Then, the third robotic arm 197 places the car lettering directly above the third suction cup 195 to be attracted. Then, the second suction cup 192 rotates along the mounting rod 191 to peel off the double-sided adhesive protective film from the car lettering. Finally, the third suction cup 195 is adjusted by the first lifting rod 194 to be placed on the guide column assembly 196 and slide onto the second conveyor belt 11.
[0032] After the label is placed on the first conveyor belt 1, the detection camera 25 is driven by the electric slide rail 21 to slide along the first conveyor belt 1. When the position and orientation of the font are detected to be different, the second lifting rod 22 and the hydraulic push rod 23 adjust the position of the mounting bracket 27 so that the label is at the center of the drive ring 28. Then, the drive motor 29 makes the drive ring 28 rotate. The drive ring 28 drives the lower gear ring 282 to drive the drive gear 216 to drive the arc-shaped clamping plate 215 on the hollow shaft 214 to converge and clamp the label. Finally, the rotating shaft 26 drives the mounting bracket 27 to rotate at a suitable angle to put the label down, thereby completing the angle adjustment of the font.
[0033] When the production line is in operation, the third robotic arm 197 moves the double-sided adhesive protective film above the mounting table 31 and then lowers it. Under the suction generated by the negative pressure machine 33, the protective film is sucked into the inner cavity 32 through the arc-shaped hole 35, preventing the protective film from falling to the ground and becoming too slippery to clean.
[0034] When the protective film in the inner cavity 32 is full, the hydraulic cylinder 314 presses down the pressure plate 34 to squeeze the protective film, making the protective film into a disc shape to save space. During the descent of the pressure plate 34, the lever 315 slides along the slide rail 316, driving the turntable 312 to rotate, so that the second arc-shaped block 313 slides along the wedge-shaped slide groove 310 into the arc-shaped hole 35 on the pressure plate 34 to complete the sealing, so that the protective film in the inner cavity 32 will not leak out when the pressure plate 34 squeezes it. At the same time, the pressure plate 34 leaves the initial position, and the slide rod 3101 loses support and, under the action of gravity, causes the first arc-shaped block 3102 to seal the arc-shaped hole 35 on the mounting platform 31, preventing the protective film from entering the inner cavity 32 during the squeezing process.
