The two-component glue can be mixed according to the actual amount, thereby reducing the waste of glue.

[0028] 3. The glue coating mechanism in the present invention can adjust the size of the glue outlet according to the width of the main layer bridge plate through the cooperation of the first driving block, the second driving block and the driving unit, and can meet the glue coating needs of the main layer bridge plates of different specifications.

[0029] 4. In the main layer bridge plate glue coating device of the present invention, the coating platform and the conveying platform can be used in combination or the coating platform can be used alone, which has high flexibility in use. Through the cooperation of the conveying platform and the coating platform, continuous coating operation of the main layer bridge plate can be realized, which is suitable for large-scale coating operations.

[0030] 5. The present invention also provides a method for coating glue on a main layer bridge plate, wherein three glue lines are formed on the surface of the main layer bridge plate by a glue coating mechanism, wherein the thickness of the middle glue line is greater than the thickness of the glue lines on both sides. When the main layer bridge plate is installed between the main layer insulation modules, the glue in the middle glue line diffuses outward to ensure that the installation surface of the main layer bridge plate is fully covered with glue, while preventing excess glue from overflowing, which results in the main layer bridge plate being unable to maintain flatness with the upper surface of the main layer insulation module after installation.

[0063] Specifically, the mobile roller 2 includes a plurality of rollers, a motor and a transmission mechanism. The rollers are arranged in parallel on the coating platform frame 1. The motor drives the rollers to rotate synchronously through the transmission mechanism. The transmission mechanism can be a gear drive, a chain drive, or a sprocket drive. In this embodiment, a transmission wheel is arranged at the end of the roller, and the motor drives the transmission wheel to rotate through a chain or a transmission belt.

[0064] As a preference, Figure 4 and Figure 5 As shown, the glue coating tube 502 includes an upper cover plate 503, a tube body 504 with an opening, a glue mixer 501 connected to the upper cover plate 503, the upper cover plate 503 and the opening 505 of the tube body 504 are detachably connected, and the glue outlet is arranged on the tube body 504. In this embodiment, the glue mixer 501 is a hollow pipeline, the glue mixer 501 is connected to one side of the upper cover plate corresponding to the opening 505 of the tube body, the upper cover plate 503 is connected to the opening 505 by screws or the like to form a relatively closed glue cavity, and the detachable connection between the upper cover plate 503 and the tube body 504 facilitates opening the glue cavity to clean and maintain the inside of the glue cavity.

[0065] Preferably, in order to facilitate the adjustment of the size of the glue outlet, a first driving block 506 and a second driving block 507 are respectively arranged at both ends of the glue cavity near the glue coating tube 502, and the first driving block 506 and the second driving block 506 are respectively connected to a driving unit 508 for driving the first driving block 506 and the second driving block 507 to move in the glue cavity along the length direction of the glue coating tube 502, and the driving unit 508 is such as a cylinder; the first driving block 506 and the second driving block 507 are arranged in contact with the inner wall of the glue cavity.

[0067] Preferably, the width of the third glue outlet 511 is greater than the width of the first glue outlet 509 and the second glue outlet 510. When glue is discharged at the same time, the amount of glue discharged from the third glue outlet 511 is greater than the amount of glue discharged from the first glue outlet 509 and the second glue outlet 510, thereby forming three glue lanes on the surface of the main layer bridge plate, and the glue thickness of the middle glue lane is greater than the glue thickness of the glue lanes on both sides. When the main layer bridge plate is subsequently installed between the main layer insulation modules, the glue lanes are squeezed, and the glue in the middle glue lane overflows to both sides, so that the position between the glue lanes is filled with glue, thereby ensuring the bonding quality of the main layer bridge plate installation.

[0068] In one embodiment, the lengths of the three glue outlets are the same, all of which are 85 mm, that is, the maximum width of the glue path formed by the first glue outlet 509 and the second glue outlet 510 is 85 mm, and the spacing between adjacent glue outlets is 10 mm.

[0069] Preferably, a waste collection box 10 is provided below the moving roller, and the waste collection box corresponds to the position below the glue coating mechanism 5.

When the main layer bridge plate is detected on the mobile roller, the mechanical arm is controlled by PLC to flip the third positioning plate to a higher surface than the conveyor roller 12, blocking the main layer bridge plate on the conveyor roller 12 from transferring to the mobile roller 2. When the main layer bridge plate is detected on the mobile roller, the third positioning plate is flipped to a lower surface than the conveyor roller 12, so that the main layer bridge block on the conveyor roller 12 is transferred to the mobile roller 2 for the next coating operation.

[0073] Preferably, a cleaning device 16 for removing dust from the surface of the main layer bridge plate is also provided above the middle area of ​​the conveying roller 12.

When both the barcode reader 20 and the barcode reader 21 exist, one of them can be selected for use. The barcode reader 20 and the barcode reader 21 can be a handheld barcode scanner or a fixed barcode scanner.

[0078] The coating platform can also be equipped with a control box 22, which is equipped with a control switch. Semi-automatic glue coating of the main layer bridge plate can be achieved by operating the control box, including manual adjustment of the position of the coating mechanism, the size of the glue outlet, the start and end time of coating, etc.

[0079] This embodiment also provides a method for applying glue to the main layer bridge plate, the method using the above-mentioned glue applying device, the method comprising:

[0080] Step 1, the PLC control system of the coating mechanism obtains the coating information of the main layer bridge plate to be coated, including the length, width, thickness and coating parameters of the main layer bridge plate, and adjusts the lateral position of the coating mechanism through the slide rail adjustment mechanism according to the width of the main layer bridge plate to be coated, so that the center of the coating mechanism is aligned with the width center of the main layer bridge plate;

[0081] During alignment, one side of the width of the main layer bridge plate remains in contact with the first positioning plate. Taking the first positioning plate as a reference, the width of the main layer bridge plate is W, and the distance between the width center of the main layer bridge plate and the first positioning plate is W / 2. The coating mechanism moves under the action of the sliding rail adjustment mechanism 7, so that the distance between the center of the coating mechanism and the first positioning plate is equal to W / 2.

[0082] Step 2: When the main layer bridge plate to be coated with glue moves along the moving roller to approach the bottom of the glue coating mechanism, the height of the glue coating mechanism is adjusted according to the thickness of the main layer bridge plate so that the glue coating mechanism is close to the upper surface of the main layer bridge plate;

[0083] When adjusting the height, the thickness D of main layer bridge plates of different specifications is different, but the height of the moving roller where the main layer bridge plates are located is consistent. The height position of the coating mechanism is adjusted by the slide rail adjustment mechanism 7 based on the height of the upper surface of the moving roller.

[0084] Step 3: When the main layer bridge plate moves to below the glue coating mechanism, the glue coating mechanism releases glue toward the upper surface of the main layer bridge plate. The glue is a two-component polyurethane glue, and the two components are mixed in the glue mixer 501 .

[0085] During the glue release process, the main layer bridge plate moves at a constant speed under the action of the moving roller, and the glue coating mechanism forms three glue paths 23 on the upper surface of the main layer bridge plate. Fig.10 As shown, the thickness of the middle rubber channel 23 is greater than the thickness of the rubber channels 23 on both sides. The rubber channels 23 extend from one end of the main layer bridging plate to the other end along the length direction of the main layer bridging plate 9. The rubber channels 23 on both sides have a margin gap from the width edge of the main layer bridging plate.

[0086] Step 4: After the main layer bridge plate completely passes under the glue coating mechanism, the glue coating mechanism stops dispensing glue and moves upward to reset through the slide rail adjustment mechanism, and executes step 3 when the next main layer bridge plate moves under the glue coating mechanism.

[0087] The coated main bridge plate enters the next process for installation. During installation, Fig.11 As shown, the main layer insulation module 25 is prefabricated on the secondary layer insulation module 24, a rigid secondary shield 26 is laid between the main layer insulation module 25 and the secondary layer insulation module 24, a flexible secondary shield 27 is laid between adjacent secondary layer insulation modules 24, the flexible secondary shield 27 and the rigid secondary shield 26 form a complete secondary layer shield, a gap for installing the main layer bridging plate 9 is formed between adjacent main layer insulation modules 25, the glued side of the main layer bridging plate 9 coated with three lines of glue is facing the flexible secondary shield 27, the main layer bridging plate 9 is embedded and installed between the main layer insulation modules, the main layer bridging plate is squeezed so that the upper surface of the main layer bridging plate is flush with the upper surface of the main layer insulation module, and the main layer bridging plate is temporarily fixed, such as adding a pressure block to keep the pressure on the main layer bridging plate until the glue is cured.
