[0001] This invention relates to the field of adhesive application equipment technology, and more specifically, to an automatic adhesive application and bonding device for automobile headliners. Background Technology

[0002] A car roof generally refers to the decorative interior trim on the roof of a car, which serves to absorb sound, insulate heat, and decorate.

[0003] Chinese patent application number CN202420048883.2 discloses an adhesive applicator for an automotive headliner, comprising a main frame, a base below the main frame, a crossbar on the main frame, a base plate on the crossbar, a connecting rod on a first pressing part, a second hydraulic rod driving a first connecting plate to fix one end of the headliner between a first support frame and a first fixing block, a fourth hydraulic rod driving a second fixing block to fix the other end of the headliner between a second fixing block and a second support frame, a third hydraulic rod driving a first moving plate to move up and down, the first moving plate driving an adhesive applicator head to move up and down, allowing the adhesive to be better distributed on the headliner more evenly, the first hydraulic rod driving the first fixing frame to move left and right, the first fixing frame driving the connecting rod and the second pressing part to move left and right, and thus driving the headliner to move left and right.

The lead screw is threadedly connected to the movable block.

[0008] Preferably, a rotatable magnetic driven disk is provided on one side of the slide, a through shaft is rotatably connected to one end surface of the slide, one end of the shaft is fixedly connected to the magnetic driven disk, and the other end of the shaft is fixedly connected to one end of a lead screw. A magnetic driving disk matching the magnetic driven disk is provided on the inner side of the trapezoidal frame, and a motor is fixedly installed on the outer surface of the trapezoidal frame. The output end of the motor is fixedly connected to the magnetic driving disk.

[0009] Preferably, vertical frames are fixedly installed on the bottom surfaces of both trapezoidal frames, fixed seats are fixedly installed on the surfaces of both support frames, and linkage blocks are slidably connected inside the two fixed seats. The two linkage blocks are respectively fixedly connected to the surfaces of the two vertical frames, and the vertical frames are slidably connected to the fixed seats through the linkage blocks.

[0010] Preferably, a threaded rod is rotatably connected inside one of the fixed seats, the threaded rod is threadedly connected to one of the linkage blocks, and a driving device is fixedly mounted on one end surface of one of the fixed seats, the output end of the driving device being fixedly connected to the threaded rod.

[0011] Preferably, position sensors for detecting the position of the canopy body are fixedly installed on the bottom surfaces of both ends of the follower frame, and a controller is fixedly installed on the surface of one of the vertical frames. The controller is electrically connected to the position sensor through a wire, the controller is electrically connected to the drive device through a wire, and the controller is electrically connected to the motor through a wire.

[0012] Preferably, a top block is fixedly installed on the bottom surface of the carriage, and movable grooves are opened on the four sides of the follower frame. One of the movable grooves is located above the magnetic driven disk and the magnetic driving disk, and the movable groove is located between the magnetic driven disk and the magnetic driving disk.

[0013] Preferably, a common glue box is provided above the surface of the follower frame, and multiple support rods are fixedly installed between the common glue box and the follower frame. Four glue dispensing solenoid valves connected to the common glue box are fixedly installed on the surface of the common glue box. A through pipe is provided inside any one of the movable slots. The through pipe is a rubber hose. The long side glue applicator is sealed and connected to the glue dispensing solenoid valve through the through pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1) When this automatic adhesive application and bonding device for car roofs is in use, as the moving block completes one stroke inside the slide, the slide carriage moves inside the slide groove. The movement of the slide carriage carries the two long-side adhesive application heads and the follower plate, causing one of the short-side adhesive application heads to apply adhesive to the edge surface of the roof body. When the slide carriage moves and the top block contacts the movable plate, as the slide continues to move, the movable plate moves the other short-side adhesive application head from one end of the mounting rail to the other end, thus applying adhesive to the other edge surface of the roof body. The two long-side adhesive application heads also complete the application of adhesive to the two corresponding long-side surfaces of the roof body. Compared with the traditional method of applying adhesive to the car roof sequentially by using a robotic arm with adhesive nozzles, this adhesive application device completes the application of adhesive to the edge surface of the roof body in one stroke, improving the adhesive application speed of the car roof and thus improving the efficiency of subsequent processing of the car roof.

[0016] 2) When this automatic adhesive application and bonding device for automotive headliners is in use, when the short-side adhesive application head and the long-side adhesive application head are reset, the linkage block slides and resets inside the fixed seat, causing the vertical frame to move. The vertical frame moves and resets, causing the trapezoidal frame and the follower frame to reset. When the linkage block moves to the initial position, the short-side adhesive application head and the long-side adhesive application head are reset, and the conveying equipment continues to convey the next headliner body to be coated. When the two position sensors detect the position of the next headliner body at the same time, the above adhesive application steps are continued. This realizes that the adhesive is applied to the edge surface of the headliner body during the continuous conveying of the headliner body, further improving the adhesive application efficiency of the headliner body.

[0019] Please see Figure 1 - Figure 11An automatic adhesive application and bonding device for automotive headliners includes two corresponding support frames 1 and a conveyor 2 disposed between them. The conveyor 2 is a conventional conveyor belt in the prior art, and the headliner body 3 to be coated with adhesive is placed on the surface of the conveyor 2. The headliner body 3 is a conventional headliner body 3 in the prior art, and the headliner body 3 is sequentially placed onto the surface of the conveyor 2 by a robotic arm. A follower frame 4 is provided above the middle of the conveyor 2, and a fixed frame 5 is fixedly installed on the bottom surface of the follower frame 4. The inner sides of the two fixed frames 5 are provided with grooves 6, and the interiors of the two grooves 6 are slidably connected to matching slides 7. Long side adhesive heads 8 for applying adhesive to the long side of the headliner body 3 are fixedly installed on both ends of the slides 7. The long side adhesive heads 8 are conventional... The existing technology uses a conventional long-side adhesive applicator 8. Two mounting rails 9 are fixedly installed on the inner sides of two fixed frames 5, located at the inner ends of the fixed frames 5. Each mounting rail 9 has a matching slider 10 slidably connected inside. Short-side adhesive applicators 11 for applying adhesive to the short sides of the ceiling body 3 are fixedly installed on the surfaces of both sliders 10. The two short-side adhesive applicators 11 are diagonally arranged. The short-side adhesive applicators 11 are conventional short-side adhesive applicators in the prior art. Trapezoidal frames 23 are fixedly installed on the bottom surfaces of both ends of the follower frame 4. Through slots 24 are formed on the surfaces of both trapezoidal frames 23. Matching follower plates 12 and movable plates 13 are slidably connected inside the two through slots 24. The surfaces of the follower plates 12 and movable plates 13 are inclined. The groove 14 has two short-side adhesive applicators 11 extending through it to the top of the follower plate 12 and the movable plate 13, respectively. One end of the follower plate 12 is fixedly connected to the surface of the carriage 7. The surface of the follower plate 12 has a connecting groove 15 that communicates with the inclined groove 14. The two long-side adhesive applicators 8 continue to follow the movement of the carriage 7 to apply adhesive to the two corresponding long-side surfaces of the canopy body 3. At this time, one of the short-side adhesive applicators 11 passes through the connecting groove 15 and the two arc-shaped blocks 16. The surface of the follower plate 12 is fixedly installed with arc-shaped blocks 16 corresponding to the position of the connecting groove 15. The arrangement of the two arc-shaped blocks 16 allows the short-side adhesive applicator 11 to better enter the interior of the connecting groove 15 when the follower plate 12 is reset, and the two arc-shaped blocks 16 are located on both sides of the connecting groove 15. When the moving block 20 completes one stroke inside the slide 19, the slide 7 moves inside the slide groove 6. The movement of the slide 7 drives the two long-side adhesive applicators 8 to move, and the movement of the slide 7 also drives the follower plate 12 to move, causing one of the short-side adhesive applicators 11 to move and apply adhesive to the edge surface of the headliner body 3. When the slide 7 moves and the top block 32 moves to contact the movable plate 13, as the slide 7 continues to move, the movement of the movable plate 13 causes the other short-side adhesive applicator 11 to move from one end of the mounting rail 9 to the other end, thereby applying adhesive to the edge surface of the other end of the headliner body 3. The two long-side adhesive applicators 8 also complete the application of adhesive to the two corresponding long-side surfaces of the headliner body 3. Compared with the traditional method of using a robotic arm to sequentially apply adhesive to the car headliner, this method is more efficient.This adhesive application equipment completes adhesive application to the edge surface of the headliner body 3 in a single stroke, increasing the adhesive application speed of the car headliner and thus improving the efficiency of subsequent processing. When the short-side adhesive head 11 and the long-side adhesive head 8 reset, the linkage block 27 slides and resets inside the fixed base 26, moving the vertical frame 22. The vertical frame 22 then resets, moving the trapezoidal frame 23 and the follower frame 4. When the linkage block 27 returns to its initial position, the short-side adhesive head 11 and the long-side adhesive head 8 have completed their reset, and the conveyor 2 continues to transport the next headliner body 3 to be coated. When both position sensors 30 simultaneously detect the position of the next headliner body 3, the above adhesive application steps continue. This allows adhesive application to be completed on the edge surface of the headliner body 3 during continuous transport, further improving the adhesive application efficiency of the headliner body 3.

The glue pump 39 is electrically connected to the controller 31 through a wire.

[0029] The steps of using this invention are as follows: When using this automatic car roof adhesive application and bonding device, the roof body 3 to be adhesiveped is first placed on the surface of the conveying device 2 using an existing robotic arm (the conveying device 2 is driven by an existing drive motor). The conveying device 2 conveys the roof body 3. When the roof body 3 moves directly under the follower frame 4, the two position sensors 30 simultaneously detect the position of the roof body 3 and transmit the signal to the controller 31. The controller 31 receives the signal and controls the drive device 29 to rotate the threaded rod 28 in the forward direction, causing the linkage block 27 to slide inside the fixed seat 26, moving the vertical frame 22. The movement of the vertical frame 22 moves the trapezoidal frame 23 and the follower frame 4 simultaneously (it should be noted that the movement of the follower frame 4...). (The speed is the same as the conveying speed of the canopy body 3). While the drive device 29 is working, the motor 25 and the glue pump 39 work simultaneously. The rotation of the motor 25 drives the magnetic drive disk 41 to rotate, and the rotation of the magnetic drive disk 41 drives the magnetic driven disk 42 to rotate (the combination of the magnetic drive disk 41 and the magnetic driven disk 42 is a conventional magnetic coupling in the prior art. The magnetic coupling is a conventional technology and will not be described in detail here). The rotation of the magnetic driven disk 42 drives the lead screw 21 to rotate, causing the movable block 20 to move inside the slide 19, which in turn drives the slide 7 to move inside the slide groove 6. The movement of the slide 7 drives the two long-side glue application heads 8 to move, and the movement of the slide 7 also drives the follower plate 12 to move. The movement of the follower plate 12 causes the inclined groove 14 to move, which in turn causes one of the sliders 10 to move. The short-side adhesive applicator 11 moves along the mounting rail 9. (At the moment the two long-side adhesive applicators 8 and one short-side adhesive applicator 11 move, the controller 31 controls the dispensing solenoid valve 36 to open. At this time, the adhesive pump 39 operates to extract the adhesive from the storage tank 38, which enters the common adhesive box 35 through the inlet 37, and then is dispensed through the opened dispensing solenoid valve 36. Finally, the adhesive enters the two long-side adhesive applicators 8 and one short-side adhesive applicator 11 through the pipe 34.) When one short-side adhesive applicator 11 moves from one end of the mounting rail 9 to the other end, it has completed the application of adhesive to one short side of the ceiling body 3. At this time, the dispensing solenoid valve 36, which supplies adhesive to one short-side adhesive applicator 11, closes. The two long-side adhesive applicators 8 continue to move with the slide 7, applying adhesive to the two corresponding long-side surfaces of the ceiling body 3. Meanwhile, one of the short-side adhesive applicators 11 exits between the connecting groove 15 and the two arc-shaped blocks 16. When the slide 7 moves, carrying the top block 32, it contacts the movable plate 13. As the slide 7 continues to move, the top block 32 presses against the movable plate 13 (at this time, the solenoid valve 36 controlling the adhesive supply to the other short-side adhesive applicator 11 opens). The movable plate 13 moves, carrying the connecting frame 17 and stretching the spring 18. The movement of the movable plate 13 causes the other short-side adhesive applicator 11 to move from one end of the mounting rail 9 to the other end, thus applying adhesive to the other side surface of the ceiling body 3. Once the other short-side adhesive applicator 11 has finished applying the adhesive...At this time, the two long-side adhesive heads 8 have also completed the adhesive application to the two corresponding long-side surfaces of the ceiling body 3. After the adhesive application is completed, the ceiling body 3 continues to be conveyed by the conveying device 2, while the adhesive application device is reset. In this scheme, when the movable block 20 completes one stroke inside the slide 19, the slide 7 moves inside the slide groove 6. The movement of the slide 7 carries the two long-side adhesive heads 8, and the movement of the slide 7 also carries the follower plate 12, causing one of the short-side adhesive heads 11 to apply adhesive to the edge surface of the ceiling body 3. When the slide 7 moves and the top block 32 moves to contact the movable plate 13, as the slide 7 continues to move, the movement of the movable plate 13 causes the other short-side adhesive head 11 to move from one end of the mounting rail 9 to the other end, thereby applying adhesive to the edge surface of the other end of the ceiling body 3. The two long-side adhesive heads 8 have also completed the adhesive application to the two corresponding long-side surfaces of the ceiling body 3. Compared with the traditional method, this method is more efficient. A robotic arm, carrying adhesive nozzles, sequentially applies adhesive to the car roof. This adhesive application equipment completes the application of adhesive to the edge surfaces of the roof body 3 in a single stroke, increasing the adhesive application speed and consequently improving the efficiency of subsequent processing. When the short-side adhesive head 11 and the long-side adhesive head 8 reset, the linkage block 27 slides and resets within the fixed base 26, moving the vertical frame 22. The vertical frame 22 then resets, moving the trapezoidal frame 23 and the follower frame 4 back to their original positions. When the linkage block 27 returns to its initial position, the short-side adhesive head 11 and the long-side adhesive head 8 have completed their reset, and the conveyor 2 continues to transport the next roof body 3 to be adhesiveped. When both position sensors 30 simultaneously detect the position of the next roof body 3, the adhesive application process continues. This allows for adhesive application to the edge surfaces of the roof body 3 during continuous transport, further improving the adhesive application efficiency.
