Description

Technical Field

[0001] This application relates to the technical field of reinforcing plate production equipment, and in particular to a reinforcing plate backing adhesive coating device. Background Technology

[0002] The reinforcing plate on a flexible printed circuit board (FPC) is a highly reliable and flexible printed circuit, often simply called a PCB. It features high wiring density, light weight, and thinness, and is primarily used in digital products such as mobile phones, laptops, and digital cameras. In existing technology, gold fingers, composed of numerous golden conductive contacts, are mounted on the front of the FPC end for signal transmission. Because flexible printed circuit boards are relatively soft and difficult to insert, a reinforcing plate is placed on the back of the existing FPC to improve the strength of the insertion points. To facilitate the adhesion of the reinforcing plate to the back of the FPC, adhesive is applied to the back of the reinforcing plate using a coating device. After adhesive application, the reinforcing plate is dried in a drying device. Finally, a film is applied to the adhesive-coated side of the reinforcing plate, and then it is wound up.

[0003] For example, Chinese patent document CN119259382B discloses an integrated adhesive tape coating machine with gluing and drying functions. It includes an unwinding mechanism, a gluing mechanism on one side of the unwinding mechanism, an air-floating drying chamber on the other side of the frame away from the unwinding mechanism, and a winding mechanism on the other side of the air-floating drying chamber away from the gluing mechanism. The gluing mechanism includes a gluing mounting frame, a transfer roller assembly at the bottom of the gluing mounting frame, a gluing unit in the middle of the gluing mounting frame, and a guide roller assembly at the top of the gluing mounting frame. The unit includes a pair of symmetrically arranged moving roller groups. A coating cartridge group is located in front of the moving roller group on the front side, and a similar coating cartridge group is located behind the moving roller group on the rear side. A left support assembly is located at one end of each moving roller group, and a right support assembly is connected to the other end of the moving roller group away from the left support assembly. The coating cartridge group includes a lower coating cartridge, which is movably mounted between two adhesive mounting brackets on both sides. An upper coating cartridge is located above the lower coating cartridge, and a feed plate connects the lower and upper coating cartridges. By using a pair of moving roller groups, adhesive can be applied to both sides of the tape simultaneously while the moving roller groups rotate and transport the tape, ensuring consistent adhesive thickness on both sides.

[0004] In the aforementioned related technologies, a pair of moving rollers rotate to transport the tape, and the coating box with connected upper and lower boxes can simultaneously apply adhesive to both sides of the tape. Then, the tape enters the drying oven for drying. After drying, it is laminated, and then the laminated tape is wound up by the winding roller. However, when applying adhesive to raw materials of different widths, it is necessary to change to a different size of coating device, which will affect the production efficiency of the entire device and increase the workload of the workers. Summary of the Invention

[0005] This application provides a device for coating adhesive on reinforcing plates, which aims to solve the problem in the related art of inconvenience in coating adhesive on reinforcing plates of different widths.

[0006] The reinforcing plate adhesive coating device provided in this application adopts the following technical solution:

[0007] A reinforcing plate adhesive coating device includes a frame and an adhesive supply assembly and an adhesive application assembly mounted on the frame. The adhesive supply assembly supplies adhesive to the adhesive application assembly, which applies the adhesive to the reinforcing plate. The adhesive application assembly includes a fixed roller fixed on the frame and an adhesive application roller sleeved on the fixed roller. The adhesive application roller is rotatably connected to the fixed roller. A mounting assembly is provided on the fixed roller to fix it to the frame. The adhesive application roller has multiple sets of adhesive application channels passing through the center of the roller, and each set of adhesive application channels has adhesive application channels on it. The channels have different lengths; a connecting groove is provided on the fixed roller, which runs through the fixed roller along the center of the fixed roller and is set horizontally. The length of the connecting groove is the same as the length of the longest glue channel on the glue coating roller. When different length glue channels correspond to the connecting groove, different reinforcing plates are glued; a cleaning component is provided on the fixed roller, which is used to clean the glue coating channel after use. The cleaning component includes a mounting block set in the mounting groove, a mounting rod slidably connected to the mounting block, and a cleaning plate fixed to the mounting rod.

[0008] By adopting the above technical solution, when applying adhesive to the reinforcing plate, the adhesive in the adhesive supply channel enters the connecting groove through the adhesive coating channel on the adhesive coating roller, and then enters the corresponding adhesive coating channel from the connecting groove. Finally, the adhesive squeezed out from the adhesive coating channel is applied to the reinforcing plate, thus achieving adhesive coating on the surface of the reinforcing plate. When adhesive needs to be applied to reinforcing plates of different widths, simply rotate the adhesive coating roller so that the adhesive coating channel of the corresponding width on the adhesive coating roller corresponds to the connecting groove on the fixed roller. Then, the adhesive in the adhesive supply assembly enters the connecting groove through the adhesive coating channel on the adhesive coating roller, and then enters the corresponding adhesive coating channel from the connecting groove. Finally, the adhesive squeezed out from the adhesive coating channel is applied to the reinforcing plate. Because the length of the connecting groove is the longest... With the same length of adhesive application channels, the connecting groove can connect adhesive application channels of different lengths, allowing for adhesive application to reinforcing plates of different widths. This makes it more convenient to apply adhesive to the surfaces of reinforcing plates of varying widths. When adjusting the adhesive application channels, the channels containing adhesive are offset from the connecting groove. This results in adhesive residue remaining in the application channels. If not cleaned promptly, the adhesive in the application channels will solidify and clog the channels during later use. When the adhesive application channel containing adhesive rotates to align with the cleaning plate, it pushes the component, causing the mounting rod and the cleaning plate fixed to the mounting rod to move. During the movement of the cleaning plate, the adhesive in the application channels is cleaned, thus reducing adhesive residue.

[0009] Optionally, the mounting assembly includes a mounting ring disposed on the end face of the fixed roller, mounting bolts passing through the mounting ring, and a mounting plate fixed to the mounting ring. The mounting plate is fixed to the frame by bolts, the mounting bolts are threaded onto the fixed roller, and the mounting ring is fixed to the frame by mounting bolts.

[0010] By adopting the above technical solution, when installing the fixed roller, the mounting ring is fixed to the end of the fixed roller by mounting bolts, and then the mounting plate is fixed to the frame, thus making it easy to install the fixed roller.

[0011] Optionally, a push assembly is provided on the frame to move the mounting rod and cleaning plate within the mounting block.

[0012] Optionally, the fixed roller has an installation groove, the cleaning component is set in the installation groove, the installation groove is set along the axial direction of the fixed roller, and one end of the installation groove is provided with an opening. Multiple installation blocks are installed into the fixed roller in sequence from the opening of the installation groove. The end of the fixed roller is provided with a limiting component, which is used to limit the position of the installation blocks in the fixed roller.

[0013] By adopting the above technical solution, when installing the cleaning components, multiple cleaning components are pushed into the installation slot in sequence through the opening of the installation slot. After all the cleaning components are placed in the installation slot, the position of the installation block in the installation slot is limited by the limiting component, which facilitates the installation and removal of the cleaning components on the fixed roller.

[0014] Optionally, the limiting component includes a limiting block inserted into the opening of the mounting groove and a limiting bolt passing through the limiting block. The limiting bolt is threaded onto the end face of the fixed roller. When the limiting block is inserted into the mounting groove, the limiting block abuts against the side of the mounting block.

[0015] By adopting the above technical solution, when multiple mounting blocks are installed in the mounting groove, the limiting block is inserted into the opening of the mounting groove, and then the limiting block is fixed on the fixed roller by the limiting bolt, so that the limiting block abuts against the mounting block, thereby limiting the position of the mounting block.

[0016] Optionally, the pushing assembly includes an air pipe passing through the fixed roller, an air hole opened on the fixed roller, and a pushing ring fixed on the mounting rod. The pushing ring abuts against the inner wall of the mounting chamber, and a connecting hole for connecting with the air hole is provided above the pushing ring. The connecting hole is provided on the mounting block and is used to connect the mounting chamber and the air hole. One end of the air hole is connected to the connecting hole, and the other end is connected to the air pipe. An air pump for inflating or deflating the air pipe is provided on the frame.

[0017] By adopting the above technical solution, when it is necessary to clean the adhesive in the coating channel, air is pumped into the air pipe using an air pump. The gas pumped into the air pipe enters the installation chamber through the air hole and connecting hole, and then pushes the push ring downward. The downward-moving push ring drives the cleaning plate downward, and the cleaning plate enters the coating channel to clean the adhesive in the coating channel. After the adhesive in the coating channel is cleaned, the air pump extracts air. During the extraction process, the air in the installation chamber is extracted, and then the push ring moves in the opposite direction. During the reverse movement, the cleaning plate also moves in the opposite direction. Finally, the cleaning plate will detach from the coating channel. When the remaining coating channels rotate to below the cleaning plate, the downward movement of the cleaning plate can continue to clean the remaining coating channels, making it more convenient to move the cleaning plate.

[0018] Optionally, the mounting block is provided with a mounting chamber, and a return spring is provided in the mounting chamber. One end of the return spring is fixed to the mounting rod, and the other end is fixed to the mounting block.

[0019] By adopting the above technical solution, when the cleaning plate needs to move in the reverse direction, the air pump draws air out. During the air drawing process, the gas in the installation chamber is extracted. Under the action of the reset spring, the push ring is pushed to reset. During the reset process of the push ring, the cleaning plate is moved in the reverse direction, which makes it easier to reset the cleaning plate.

[0020] Optionally, a conveying assembly is provided on the frame for conveying the reinforcing plate; the conveying assembly includes a first conveying roller rotatably connected to the frame and a second conveying roller rotatably connected to the frame, the reinforcing plate to be coated is located between the first conveying roller and the second conveying roller, and a conveying motor is provided on the frame, the output shaft of the conveying motor being fixedly connected to the first conveying roller.

[0021] By adopting the above technical solution, the conveying motor drives the first conveying roller to rotate. Since the reinforcing plate is set between the first and second conveying rollers, it then drives the reinforcing plate to move, thereby enabling the gluing assembly to apply glue to different positions of the reinforcing plate.

[0022] Optionally, the frame is provided with a drive assembly for driving the coating roller to rotate. The drive assembly includes a drive gear ring fixed on the coating roller, a drive gear rotatably connected to the frame, and a drive motor fixed on the frame. The output shaft of the drive motor is fixedly connected to the drive gear, and the drive gear and the drive gear ring mesh.

[0023] By adopting the above technical solution, when it is necessary to adjust the glue application channel, the drive motor drives the drive gear to rotate, the drive gear drives the drive gear ring to rotate, and the drive gear ring drives the drive glue application roller to rotate. Then, glue application channels of different lengths can be aligned with the connecting groove, and glue can be applied to the reinforcing plate positions of different widths.

[0024] Optionally, a collection trough is provided below the cleaning plate, and rotating shafts are fixedly installed at both ends of the collection trough. The collection trough is rotatably connected to the frame through the rotating shafts.

[0025] By adopting the above technical solution, during the downward movement of the cleaning plate, the adhesive in the glue application channel is pushed downward, and the downward-flowing adhesive falls into the collection tank. When it is necessary to clean the adhesive in the collection tank, the collection tank is rotated by the rotating shaft, so that the opening of the collection tank faces downward, which facilitates the cleaning of the adhesive in the collection tank.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When applying adhesive to reinforcing plates of different widths, rotate the adhesive roller so that the adhesive channel of the corresponding width on the adhesive roller corresponds to the connecting groove on the fixed roller. Then, the adhesive in the adhesive supply assembly will enter the connecting groove through the adhesive channel on the adhesive roller, and then enter the corresponding adhesive channel from the connecting groove. Finally, the adhesive squeezed out from the adhesive channel is applied to the reinforcing plate.

[0028] 2. Pushing the component moves the mounting rod and the cleaning plate fixed on the mounting rod. During the movement of the cleaning plate, the adhesive in the adhesive channel is cleaned, which can reduce the amount of adhesive residue in the adhesive channel. Attached Figure Description

[0038] The following combination Figures 1-8 This application will be described in further detail.

[0039] This application discloses an adhesive coating device for reinforcing plates. (Refer to...) Figures 1 to 3 A reinforcing plate adhesive coating device includes a frame 01 and an adhesive supply assembly 1 and an adhesive coating assembly 2 mounted on the frame 01. A conveying assembly is also mounted on the frame 01. The conveying assembly is used to convey the reinforcing plate. The adhesive supply assembly 1 is used to supply adhesive to the adhesive coating assembly 2. Then, the adhesive coating assembly 2 is used to apply adhesive to the surface of the reinforcing plate conveyed by the conveying assembly. The adhesive coating assembly 2 can also apply adhesive to reinforcing plates of different widths. After the adhesive is applied, the conveying assembly conveys the reinforcing plate into a drying oven. After it is removed from the drying oven, it is laminated. After lamination, it is wound up by a take-up roller.

[0040] Reference Figures 1 to 3 The glue supply assembly 1 includes a lower housing 11 fixed on the frame 01, an upper housing 12 hinged to the lower housing 11, and a glue supply pipe (not shown in the figure). A glue supply cavity 13 is provided between the upper housing 12 and the lower housing 11. One end of the glue supply pipe is connected to the glue supply cavity 13. A glue supply pump (not shown in the figure) is provided on the frame 01. The glue supply pump is used to connect with the glue supply pipe. The glue pump liquid is introduced into the glue supply cavity 13 through the glue supply pipe. Then the glue liquid in the glue supply cavity 13 will enter the glue application assembly 2. The glue application assembly 2 applies glue to the conveyed reinforcing plate.

[0041] Reference Figures 2 to 4The glue application assembly 2 includes a fixed roller 21 fixed on the frame 01 and a glue application roller 22 sleeved on the fixed roller 21. The glue application roller 22 is configured as a ring structure and is rotatably connected to the fixed roller 21. The fixed roller 21 is provided with an installation assembly 4, which fixes the fixed roller 21 to the frame 01. Bearings are provided at both ends of the glue application roller 22, and the glue application roller 22 is rotatably connected to the frame 01 through the bearings. Multiple sets of glue application channels 23 are opened on the glue application roller 22. The multiple sets of glue application channels 23 pass through the center of the glue application roller 22, and the length of the glue application channel 23 on each set of glue application roller 22 is different. A connecting groove 24 is opened on the fixed roller 21. The connecting groove 24 passes through the fixed roller 21 along the center of the fixed roller 21 and is horizontally arranged. The length of the connecting groove 24 is the same as the length of the longest glue application channel 23 on the glue application roller 22.

[0042] Adjust the position of the coating roller 22 so that the coating channel 23 on the coating roller 22 is connected to the opening of the glue supply cavity 13. The glue supply pump introduces the glue into the glue supply cavity 13 through the glue supply pipe. Then, the glue in the glue supply cavity 13 is squeezed into the coating channel 23 on the coating roller 22. The glue entering the coating channel 23 will enter the connecting groove 24. The glue entering the connecting groove 24 will flow out through the coating channel 23 of the same width. The outflowing glue will be applied to the back of the reinforcing plate. At this time, the purpose of coating the reinforcing plate can be achieved. After the reinforcing plate is coated, it is transported to the drying oven for drying by the conveying component.

[0043] Since the position of the connecting groove 24 is fixed, when applying glue to reinforcing plates of different widths, it is only necessary to rotate the position of the glue application roller 22 so that the glue application channel 23 on the glue application roller 22 is connected to the connecting groove 24. Since there are multiple glue application channels 23 on the glue application roller 22, and the length of each glue application channel 23 is different, by rotating the glue application roller 22, the required glue application channel 23 is aligned with the connecting groove 24, so that the purpose of applying glue to reinforcing plates of different widths can be achieved.

[0044] Reference Figures 2 to 6 The mounting assembly 4 includes a mounting ring 41 disposed on the end face of the fixed roller 21, a mounting bolt 42 passing through the mounting ring 41, and a mounting plate 43 fixed on the mounting ring 41. The mounting plate 43 is fixed to the frame 01 by bolts, the mounting bolt 42 is threadedly connected to the fixed roller 21, and the mounting ring 41 is fixed to the fixed roller 21 by the mounting bolt 42, thereby fixing the fixed roller 21 to the frame 01. In this embodiment, two mounting assemblies 4 are provided, and the two mounting assemblies 4 are disposed at both ends of the fixed roller 21, which can improve the installation strength of the fixed roller 21.

[0045] When adjusting the glue application channel 23 of different lengths, the glue application channel 23 that originally corresponded to the connecting groove 24 will rotate and no longer correspond to the connecting groove 24. At this time, glue will remain in the glue application channel 23. After a certain period of time, the glue in the glue application channel 23 will solidify and block the glue application channel 23. When used again, it will cause uneven glue application or failure to dispense glue. In this embodiment, a cleaning component 5 is provided on the fixed roller 21. The cleaning component 5 is used to clean the glue application channel 23 after use, reduce the glue residue in the glue application channel 23, and make it more convenient in subsequent use.

[0046] Reference Figures 2 to 5 An installation groove 02 is provided on the fixed roller 21, and the cleaning component 5 is set in the installation groove 02. The installation groove 02 is set along the axial direction of the fixed roller 21, and one end of the installation groove 02 is provided with an opening. At this time, the cleaning component 5 can be installed into the installation groove 02. The installation groove 02 is provided with a clearance groove 03 facing the glue coating roller 22. The cleaning component 5 can move into the glue coating channel 23 through the clearance groove 03, thereby cleaning the glue liquid in the glue coating channel 23.

[0047] Reference Figures 2 to 5 The cleaning component 5 includes a mounting block 51 disposed in the mounting groove 02, a mounting rod 52 slidably connected to the mounting block 51, and a cleaning plate 53 fixed to the mounting rod 52. The side of the cleaning plate 53 facing away from the mounting rod 52 is set as an arc surface, so that one side of the cleaning plate 53 and the fixed roller 21 are on the same circumference, which facilitates the rotation of the glue application roller 22 on the fixed roller 21. A pushing component 7 is provided on the frame 01. The pushing component 7 is used to push the mounting rod 52 and the cleaning plate 53 in the mounting block 51 to move. During the movement, the glue in the glue application channel 23 can be cleaned, thereby reducing the glue residue in the glue application channel 23.

[0048] Reference Figures 2 to 5 An installation chamber 04 is provided inside the installation block 51. A return spring 05 is provided inside the installation chamber 04. One end of the return spring 05 is fixed to the installation rod 52, and the other end is fixed to the installation block 51. When the pushing assembly 7 pushes the installation rod 52 and the cleaning plate 53 downward, the cleaning plate 53 will extend out of the relief groove 03 and enter the glue application channel 23, and then push the glue in the glue application channel 23 downward, and finally detach from the glue application channel 23. In this embodiment, when the cleaning plate 53 moves downward, the relief groove 03 on the installation groove 02 faces downward to connect the glue application channel 23 and the installation groove 02, and then the cleaning plate 53 in the relief groove 03 can be moved into the glue application channel 23.

[0049] Multiple cleaning components 5 are set along the length of the mounting groove 02. The pushing component 7 is used to push multiple cleaning plates 53 to move simultaneously and clean the glue in the glue application channel 23. Since there are two glue application channels 23 in each group, the cleaning component 5 can only clean one downward-facing glue application channel 23 at a time. After one glue application channel 23 in each group is cleaned, the glue application roller 22 rotates 180 degrees and cleans the other glue application channel 23 through the cleaning plate 53, thereby reducing the glue residue in the glue application channel 23 and facilitating the subsequent use of the glue application channel 23.

[0050] When the glue application channel 23 needs to be cleaned, the pushing component 7 pushes multiple mounting rods 52 and cleaning plates 53 to move simultaneously. However, when cleaning a shorter glue application channel 23, the cleaning plate 53 that does not correspond to the glue application channel 23 cannot move downward. The pushing component 7 can only push the cleaning plate 53 and mounting rod 52 corresponding to the glue application channel 23 downward. Then, the downward-moving cleaning plate 53 cleans the glue application channel 23. When cleaning glue application channels 23 of different lengths, the number of downward-moving cleaning plates 53 is also different, thereby achieving the purpose of cleaning glue application channels 23 of different lengths.

[0051] Reference Figures 2 to 6 A limiting component 6 is provided at the end of the fixed roller 21. The limiting component 6 is used to limit the position of the mounting block 51 inside the fixed roller 21. The limiting component 6 includes a limiting block 61 inserted into the opening of the mounting groove 02 and a limiting bolt 62 passing through the limiting block 61. The limiting bolt 62 is threaded to the end face of the fixed roller 21. When the limiting block 61 is inserted into the mounting groove 02, the limiting block 61 abuts against the side of the mounting block 51. When the limiting block 61 is fixed to the end face of the fixed roller 21 by the limiting bolt 62, the position of the mounting block 51 is limited. At this time, the mounting block 51 cannot move along the length direction of the fixed roller 21.

[0052] Reference Figures 2 to 5The pushing component 7 includes an air pipe 71 passing through the fixed roller 21, an air hole 72 formed on the fixed roller 21, and a pushing ring 73 fixed on the mounting rod 52. The pushing ring 73 abuts against the inner wall of the mounting chamber 04, and a connecting hole 74 for connecting with the air hole 72 is provided above the pushing ring 73. The connecting hole 74 is provided on the mounting block 51 and is used to connect the mounting chamber 04 and the air hole 72. One end of the air hole 72 is connected to the connecting hole 74, and the other end is connected to the air pipe 71. In this embodiment, each mounting block 51 is provided with one connecting hole 74, and multiple air holes 72 are provided. Air holes 72 are spaced apart along the length of the fixed roller 21, and multiple air holes 72 and multiple connecting holes 74 correspond one-to-one. At the same time, an air pump (not shown in the figure) is provided on the frame 01. The air pump is used to connect to the air pipe 71. The air pump inflates the air pipe 71. The gas in the air pipe 71 will enter the mounting chamber 04 through the air holes 72 and connecting holes 74. The gas entering the mounting chamber 04 will push the push ring 73 to move down. The moving push ring 73 will push the cleaning plate 53 to move down. The moving cleaning plate 53 will move into the glue application channel 23 to clean the glue in the glue application channel 23.

[0053] During the downward movement of the cleaning plate 53, the return spring 05 is compressed. After the adhesive in the adhesive application channel 23 is cleaned, the air pump draws air out. At this time, the gas in the installation chamber 04 is drawn out, and then the cleaning plate 53 is reset under the action of the return spring 05, which facilitates the subsequent application of adhesive to the adhesive application channel 23.

[0054] Reference Figures 2 to 5 The conveying assembly includes a first conveying roller rotatably connected to the frame 01 and a second conveying roller rotatably connected to the frame 01. The reinforcing plate to be coated with adhesive is located between the first and second conveying rollers. A conveying motor is installed on the frame 01, and the output shaft of the conveying motor is fixedly connected to the first conveying roller. The conveying motor drives the first conveying roller to rotate, and then conveys the reinforcing plate between the first and second conveying rollers. At the same time, a limiting roller 8 is rotatably connected to the frame 01. The limiting roller 8 is used to limit the conveyed reinforcing plate. The limiting roller 8 includes a rotating part 81 and a limiting part 82. Two limiting parts 82 are provided, and the reinforcing plate is located between the two limiting parts 82. The reinforcing plate can be limited during the conveying process.

[0055] Reference Figures 2 to 5An adjustment component 9 is provided on the limiting roller 8. The adjustment component 9 is used to adjust the position of the two limiting parts 82, and then the reinforcing plates of different widths can be limited. The adjustment component 9 includes a moving block 91 fixed on the limiting part 82 and a bidirectional screw 92 rotatably connected to the limiting roller 8. The limiting part 82 is slidably connected to the rotating part 81, and the moving block 91 and the bidirectional screw 92 are threadedly connected. By rotating the bidirectional screw 92, the bidirectional screw 92 drives the two limiting parts 82 to move away from or closer to each other, and then the reinforcing plates of different widths are limited.

[0056] Reference Figures 2 to 6 The frame 01 is provided with a drive assembly 10 for driving the coating roller 22 to rotate. The drive assembly 10 includes a drive gear ring 101 fixed on the coating roller 22, a drive gear 102 rotatably connected to the frame 01, and a drive motor 103 fixed on the frame 01. The output shaft of the drive motor 103 is fixedly connected to the drive gear 102, and the drive gear 102 and the drive gear ring 101 mesh. When the drive motor 103 rotates, it can drive the drive gear 102 to rotate. During the rotation of the drive gear 102, it will drive the drive gear ring 101 to rotate. The drive gear ring 101 drives the coating roller 22 to rotate. In this embodiment, the drive gear ring 101 is fixed to the coating roller 22 by bolts.

[0057] Reference Figures 2 to 5 A collection trough 06 is provided below the cleaning plate 53. Rotating shafts 07 are fixedly installed at both ends of the collection trough 06. The collection trough 06 is rotatably connected to the frame 01 through the rotating shafts 07. When cleaning the glue in the glue application channel 23, the glue pushed by the cleaning plate 53 will flow into the collection trough 06. When it is necessary to clean the glue in the collection trough 06, simply rotate the collection trough 06 so that the opening of the collection trough 06 faces downward, and then it is convenient to clean the glue in the collection trough 06.

[0058] Reference Figures 2 to 8 A locking assembly 3 is provided on the frame 01. The locking assembly 3 is used to fix the position of the rotating shaft 07 and prevent the collection tank 06 from rotating. The locking assembly 3 includes a sliding rod 31 slidably connected to the rotating shaft 07 and a locking rod 32 fixed on the sliding rod 31. A locking groove 33 is provided on the frame 01. When the locking rod 32 is in the locking groove 33, the position of the rotating shaft 07 is fixed, and the position of the collection tank 06 is fixed. When it is necessary to rotate the collection tank 06, the locking rod 32 is pulled out of the locking groove 33. Then, by rotating the locking rod 32, the locking rod 32 will drive the sliding rod 31 and the rotating shaft 07 to rotate, thereby adjusting the position of the collection tank 06.

[0059] The implementation principle of the reinforcing plate adhesive coating device in this application embodiment is as follows: When adhesive needs to be applied to the reinforcing plate, the position of the adhesive roller 22 is adjusted so that the adhesive channel 23 on the adhesive roller 22 corresponds to the connecting groove 24. During the adhesive supply process, the adhesive liquid enters the adhesive channel 23 through the adhesive channel 23 and then enters the connecting groove 24 through the connecting groove 24 into the other half of the adhesive channel 23. Then, the adhesive liquid is applied to the reinforcing plate through the adhesive channel 23. When adhesive needs to be applied to reinforcing plates of different widths, the adhesive roller 22 is rotated by the drive component 10. During the rotation of the adhesive roller 22, the required adhesive channel 23 corresponds to the connecting groove 24. At this time, adhesive can be applied to reinforcing plates of different widths, which makes the adjustment process more convenient.

[0060] After adjustment, the glue application channel 23, which no longer corresponds to the connecting groove 24, will contain glue. At this time, align the glue application channel 23 with the cleaning plate 53, and inflate the air pipe 71 with an air pump. The gas will enter the installation chamber 04 and push the push ring 73 downward. During the downward movement of the push ring 73, the cleaning plate 53 will be pushed downward. During the downward movement of the cleaning plate 53, the glue in the glue application channel 23 will be cleaned. The cleaned glue will fall into the collection tank 06, thereby reducing the glue residue in the glue application channel 23.

[0061] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
