[0002] An automated adhesive bonding device is an intelligent machine integrating automated control, precision mechanical transmission, and an adhesive supply system. Its core function is to automatically complete a series of processes—positioning the materials to be bonded, precisely applying the adhesive, bonding the materials, and applying pressure for curing—through preset programs or sensor sensing. This device is widely used in electronics, packaging, automotive, and medical device industries, significantly improving the efficiency and precision of bonding operations, reducing errors and adhesive waste caused by manual operation, and adapting to the bonding needs of different materials through modular design. It is an important piece of equipment in modern automated manufacturing production.

[0003] A search revealed Chinese Patent Publication No. CN220126689U, which discloses an automatic adhesive coating device. The device includes an adhesive tank and a rotatable applicator roller positioned above the adhesive tank. A scraper roller is also rotatably positioned above the adhesive tank, close to the applicator roller, forming a control gap for controlling the adhesive thickness. A scraper blade is positioned above the scraper roller and adheres to its surface to scrape adhesive off the roller. Both ends of the scraper roller are equipped with… The bearing housing is slidably mounted on the external frame to drive the scraper roller to slide, thereby adjusting the gap between the scraper roller and the glue roller. This utility model of automatic glue coating device can effectively achieve the effect of adjustable glue thickness on the glue roller by setting the scraper roller and the bearing housing. However, glue overflows onto the board surface, dirtys the workbench, and generates a large amount of glue-containing waste due to the need to clean the workbench frequently. In addition, rolling can cause the sheet to shift forward, requiring the operator to manually pull the sheet, which is extremely inconvenient. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Reference Figure 1 and Figure 2 This utility model provides an embodiment of an automatic glue bonding device, comprising a front worktable 12, a glue container 18, and a motor 17. The device is characterized in that: a glue inlet valve A19 is installed at the rear end of the glue container 18; a spring-loaded cylinder 20 is installed at the rear end of the glue inlet valve A19; a valve 21 is provided on the outside of the cylinder 20; a glue nozzle 22 is installed at the rear end of the cylinder 20; and a roller is provided on the top of the roller 1. Roller 2 of the second part is equipped with bearing seats 29 at both ends. A cylinder 3 27 is installed on the top of the bearing seat 29 of the second part. A piston 28 is set on the outside of the cylinder 3 27 of the second part. A bearing seat 29 is set on the outside of the piston 28 of the second part. A screw 24 is installed on the top of the cylinder 3 27 of the second part. A screw 25 is set on the bottom left side of the screw 24 of the second part. A screw 26 is set on the bottom right side of the screw 24 of the second part. A rotary encoder 5 is installed at one end of the roller 2 of the second part. Specifically, after the equipment starts, it first executes the power-on, power-on, and air-in procedures. After the equipment completes initialization and enters the reset state, the glue inlet valve A19 remains open, while the air valve 21 corresponding to cylinder 20 is closed. The system is in standby mode, waiting for the glue application command. Once the operator presses the glue application button, the equipment immediately responds and starts the glue application program. The glue inlet valve A19 quickly closes, and the air valve of cylinder 16 opens. Cylinder 16 begins to move, driving the connected glue nozzle 22 towards the board 13. During the movement, the equipment monitors the position of the glue nozzle 22 in real time through the position detection device to ensure that it accurately moves to the designated position on the left side of the board 13 and then stops. Immediately afterwards, the air inlet valve 21 of cylinder 20 opens, and compressed air enters cylinder 20. At the same time, the glue dispensing valve B23 also opens. Under the thrust of cylinder 20, the glue is forced into the glue nozzle 22 through the connected tube and evenly squeezed onto the bonding surface of the board 13, starting the glue application operation. During the process, cylinder 216 continues to drive the dispensing nozzle 22 to move from the left side to the right side of the board 13. The position detection device continues to work, precisely controlling the movement trajectory and position of the dispensing nozzle 22 to ensure that the glue can evenly cover the entire left to right area of ​​the bonding surface of the board 13. When the dispensing nozzle 22 reaches the designated position on the right side of the board 13, the equipment sequentially performs the operation of closing the dispensing valve B23 and the air valve 21 of cylinder 20, stopping the glue extrusion. The glue inlet valve A19 reopens, and cylinder 21... Under the reset action of the internal spring, a negative pressure is formed inside cylinder 20, which draws the glue from the glue inlet channel to reserve glue for the next application. After the glue is drawn in, cylinder 16 drives the dispensing nozzle 22 to return to the initial position along the original path. The entire glue application process is completed, and the equipment enters the standby state again, waiting for the next glue application button to be pressed to start a new round of glue application. The rear end of the front worktable 12 is fixedly connected to the rear worktable 4, and the roller 2 is equipped with a roller 2 rotary encoder 5.

[0016] Reference Figure 1 , Figure 2 and Figure 3 A plate 13 is provided on the top of the front worktable 12 of the dispensing valve A, a sheet 14 is provided on the outside of the plate 13 of the dispensing valve A, a cylinder 16 is installed on the rear side of the top of the front worktable 12 of the dispensing valve A, a roller bearing seat suspension device 3 is installed on both the left and right ends of the top of the front worktable 12 of the dispensing valve A, a dispensing valve A 15 is provided on the left side of the top of the front worktable 12 of the dispensing valve A, a rear worktable 4 is fixedly connected to the rear side of the front worktable 12 of the dispensing valve A, and a roller rotary encoder 5 is installed on the right side of the roller 2 of the dispensing valve A. Specifically, the device includes a mode selection switch, providing three operating modes: calibration mode, straight-through mode, and reciprocating mode. Calibration mode: First, the speed of motor 17 should be adjusted to a low level. Then, the sheet material 13 is pushed into the roller inlet, and the foot switch 11 is pressed and released so that the system records the angle W required for winding the sheet material 13. If changes occur during production, recalibration must be performed. Straight-through mode: In this mode, the sheet material 14 and the glued sheet material 13 are pushed into the roller inlet together. The foot switch 11 is pressed. When the rotary encoder 5 of roller 2 reaches the angle W, cylinder 3 27 will lift, and simultaneously the motor... 17 stops working. After bonding is completed, the product will be sent to the next station, and then this operation process will be repeated. Reciprocating mode: When the rotary encoder 5 of roller 2 counts to angle W, motor 17 will reverse, causing sheet 14 and board 13 to retract. The remaining operations are similar to the straight-through mode and need to be repeated. The right side of the front workbench 12 is equipped with an electrical control box 10, which has a clear functional division on the top and rear side: an indicator light 6 is provided on the left, and a power switch 7 is provided on the right; a mode selection device 8 is specially set on the top right, and a work start button 9 is installed on the front. The bottom of the electrical control box 10 is also connected to a foot switch 11 for control.

[0017] Reference Figure 1 An electrical control box 10 is installed on the right side of the front workbench 12. An indicator light 6 is set on the left side of the top rear side of the electrical control box 10. A power switch 7 is set on the right side of the top rear side of the electrical control box 10. A mode selection 8 is set on the right side of the top of the electrical control box 10. A work start 9 is installed on the front side of the top of the electrical control box 10. A foot switch 11 is set on the bottom of the electrical control box 10. Specifically, an electrical control box 10 is installed on the right side of the aforementioned front workbench 12. An indicator light 6 is provided on the left side of the top rear side of the electrical control box 10, a power switch 7 is provided on the right side of the top rear side, a mode selection 8 is provided on the right side of the top, a work start 9 is installed on the front side of the top, and a foot switch 11 is provided at the bottom.

[0018] Working principle: When the equipment is started, the power and air supply operations are performed first. After the equipment completes initialization, it enters the reset state. At this time, the glue inlet valve A19 is in the open state, while the air valve 21 corresponding to cylinder 20 remains closed. The entire system is in standby state, waiting for the glue application command. When the operator presses the glue application button, the equipment responds immediately and starts the glue application program. The glue inlet valve A19 closes quickly, and at the same time, the air valve of cylinder 16 opens. Cylinder 16 starts to move, driving the glue nozzle 22 connected to it, which contains the glue valve B23, to move towards the board 13. During the movement, the equipment monitors the position of the dispensing nozzle 22 in real time through a position detection device, ensuring that it accurately moves to the designated position on the left side of the board 13 and stops. Immediately afterwards, the air inlet valve 21 of cylinder 20 opens, allowing compressed air to enter cylinder 20. Simultaneously, the dispensing valve B23 also opens. Under the thrust of cylinder 20, the adhesive is forced through the connected tube into the dispensing nozzle 22 and evenly extruded onto the bonding surface of the board 13, initiating the adhesive application process. During this process, cylinder 16 continues to move the dispensing nozzle 22 from the left side of the board 13 to the right side. The position detection device remains operational throughout, precisely controlling the movement trajectory and position of the dispensing nozzle 22 to ensure the adhesive is applied evenly. The device can evenly cover the entire left to right area of ​​the bonding surface of the board 13. When the dispensing nozzle 22 moves to the designated position on the right side of the board 13, the device sequentially performs the operation of closing the dispensing valve B23 and the air valve 21 of cylinder 20, stopping the extrusion of glue. The glue inlet valve A19 reopens. Under the reset action of the spring inside cylinder 20, a negative pressure is formed inside cylinder 20, which draws the glue from the glue inlet channel to reserve glue for the next application. After the glue is drawn in, cylinder 26 drives the dispensing nozzle 22 back to the initial position along the original path. The entire glue application process ends, and the device enters standby mode again, waiting for the next glue application button to be pressed to start a new round of glue application. Calibration Mode: First, adjust the motor speed to a lower setting. Push the sheet material 13 into the roller inlet, then press and release the foot switch 11. The system records the required angle W for winding the sheet material 13. Recalibration is required when production changes occur. Straight-through Mode: Push the sheet material 14 and the glued sheet material 13 together into the roller inlet. Press the foot switch 11. When the rotary encoder 5 of roller two counts to angle W, cylinder three 27 lifts up and motor 17 stops. After bonding, it is sent to the next station. The operation is repeated. Reciprocating Mode: When the rotary encoder 5 of roller two counts to angle W, motor 17 reverses to retract the sheet material 14 and sheet material 13. The remaining operations are similar to the straight-through mode and must be repeated.
