[0022] Please see Figures 1 to 2 This utility model provides an adhesive wiping device for wiping the nozzle of an adhesive dispensing device. The adhesive wiping device includes a base frame 1, a ribbon 2, a transmission module, a control module, and a cleaning module. The transmission module and the cleaning module are both assembled on the base frame 1. The ribbon 2 has two fixed ends and a cleaning part located between the two fixed ends, and the cleaning part is formed as a cleaning surface. The transmission module includes a driving wheel 3, a driven wheel 4, and a driving member 5. The driving member 5 is electrically connected to the control module and connected to the driving wheel 3. The two fixed ends are respectively wound around the driving wheel 3 and the driven wheel 4. The cleaning surface is used to conform to the contact surface of the nozzle. The cleaning module is disposed around the cleaning part and is used to spray cleaning agent to the cleaning part.

[0023] In this embodiment of the invention, the control module controls the drive component 5 to open, causing the drive component 5 to control the rotation of the drive wheel 3. The two fixed ends of the ribbon 2 are respectively wound around the drive wheel 3 and the driven wheel 4, so that the drive wheel 3 drives the ribbon 2 to move and the ribbon 2 drives the driven wheel 4 to rotate. Furthermore, the cleaning part of the ribbon 2 is in contact with the nozzle, thus cleaning the nozzle and realizing an automated glue-wiping process. In addition, a cleaning module is provided around the cleaning part, which can spray cleaning agent onto the cleaning part of the ribbon 2, so that the ribbon 2 is soaked in cleaning agent, which can more thoroughly wipe away residual glue on the nozzle.

[0024] It should be noted that the fixed ends are the two outermost edges of the ribbon 2, which are respectively wound and fixed to the driving wheel 3 and the driven wheel 4. However, the cleaning part of the ribbon 2 is also partially wound on the driving wheel 3 and / or the driven wheel 4 in the initial state of the device. The movement of the ribbon 2 means that the ribbon 2 moves from the driving wheel 3 to the driven wheel 4, or from the driven wheel 4 to the driving wheel 3.

[0025] Understandably, in some embodiments, the adhesive application device also includes a control panel 13, so that the user can control whether the first drive unit 5 is turned on by operating the control panel 13.

[0026] For example, the cleaning agent can be alcohol, etc. The drive component 5 can be a motor or cylinder, etc.

[0027] Furthermore, in some embodiments, the cleaning module includes a cleaning agent spray block, a cleaning part is attached to the cleaning agent spray block to form a cleaning surface, and the side of the cleaning surface facing away from the cleaning agent spray block is used to attach to the contact surface of the nozzle.

[0028] Specifically, the cleaning module may include a cleaning agent spray block having at least one flat surface, allowing it to support the cleaning portion of the ribbon 2. The cleaning portion of the ribbon 2 has a cleaning surface that can be fitted and connected to the contact surface of the nozzle, enabling the ribbon 2, soaked in cleaning agent, to clean the nozzle. This configuration allows the cleaning agent spray block to spray cleaning agent to improve the cleaning effect of the ribbon 2 while also providing support for it.

[0029] In some embodiments, the cleaning agent spray block can be disposed around the periphery of the cleaning part and spaced apart from the cleaning part, as long as the sprayed cleaning agent is directed toward the cleaning part.

[0030] Furthermore, in some embodiments, the cleaning agent spray block is screwed, connected to the base frame 1 via a tongue-and-groove joint, or bonded.

[0031] Specifically, the cleaning agent spray block can be detachably connected to the base frame 1, for example, by means of screw connection, snap-fit, or adhesive.

[0032] Furthermore, in some embodiments, the cleaning module also includes a solenoid valve 7 for controlling the opening or closing of the cleaning agent spray block, the solenoid valve 7 being electrically connected to the control module. The control module can control whether the cleaning agent spray block sprays cleaning agent by controlling the opening or closing of the solenoid valve 7.

[0033] Furthermore, in some embodiments, the adhesive application device also includes a sensing module electrically connected to the control module. The sensing module is used to acquire the moving length of the ribbon 2. By acquiring the moving length of the ribbon 2 through the sensing module, the moving length of the ribbon 2 can be controlled, preventing the fixed end from completely disengaging from the drive wheel 3, and preventing the transmission module from continuing to operate even after the ribbon 2 has been used up.

[0034] Furthermore, in some embodiments, the sensing module includes a sensing shaft 8 rotatably connected to the base frame 1 and a sensor 9 disposed on the sensing shaft 8; a ribbon 2 is disposed on the outer periphery of the sensing shaft 8 for driving the sensing shaft 8 to rotate; the sensor 9 is used to detect the rotation angle of the sensing shaft 8; the sensor 9 is electrically connected to the control module.

[0035] Specifically, during the movement of the ribbon 2, the sensing shaft 8 can be rotated, and the sensor 9 can detect the rotation angle of the sensing shaft 8 and transmit it to the control module, so that the control module can obtain the moving length of the ribbon 2. Because of the sensor 9 and the sensing shaft 8, the moving length of the ribbon 2 can be accurately grasped, avoiding the situation where the ribbon 2 is used up while the transmission module is still running.

[0036] Furthermore, in some embodiments, the adhesive application device also includes several auxiliary shafts 10, which are rotatably connected to the base frame 1, and the ribbon 2 is connected to the driven wheel 4 via each of the auxiliary shafts 10 via the driving wheel 3.

[0037] Specifically, the central axis of the auxiliary shaft 10 is orthogonal to the direction of movement of the ribbon 2. The ribbon 2 is connected to the driving wheel 3 and the driven wheel 4 through the auxiliary shaft 10. The driving wheel 3 rotates under the drive of the driving component 5 and drives the ribbon 2 to move. The ribbon 2 drives the auxiliary shaft 10 and the driven wheel 4 to rotate. Through the auxiliary shaft 10, the ribbon 2 can be stretched during the movement, so that the ribbon 2 can move and wipe better and is not easy to loosen.

[0038] In some specific embodiments, the ribbon 2 is connected to the driven wheel 4 via the sensing shaft 8, the cleaning agent spray block and each auxiliary shaft 10. That is to say, the sensing shaft 8 and the cleaning agent spray block can also spread the ribbon 2.

[0039] Furthermore, in some embodiments, the adhesive application device also includes a damper 11, which is coaxially arranged with the driven wheel 4. By providing the damper 11 at the driven wheel 4, the ribbon 2 is less likely to loosen during the pulling process.

[0040] Furthermore, in some embodiments, the adhesive application device further includes a buffer 12, which is disposed on the side of the cleaning surface away from the contact surface.

[0041] For example, the buffer 12 can be a sponge or a flexible silicone part, etc. By providing the buffer 12 on the side of the ribbon 2 away from the nozzle, the ribbon 2 can be cushioned to a certain extent, thereby moving the ribbon 2 better.

[0042] In some specific embodiments, the buffer 12 is disposed between the ribbon 2 and the cleaning agent spray block, so that the ribbon 2 can be cushioned during movement.

[0043] Furthermore, in some specific embodiments, the adhesive application device is electrically connected to the dispensing equipment. The specific working process of the adhesive application device can be as follows: after the dispensing equipment completes the dispensing and moves the nozzle's contact surface to adhere to the clean surface of the ribbon 2, the control module controls the solenoid valve 7 to open, and simultaneously controls the drive module. The drive module drives the drive wheel 3 to rotate, causing the ribbon 2 to move. After the adhesive application is completed, the control module controls the drive module to stop the ribbon 2 from moving; subsequently, the dispensing equipment removes the nozzle, and finally, the control system can control the drive module to rotate the drive wheel 3 in the opposite direction, causing the ribbon 2 to move back, thus retracting the ribbon 2.

[0044] Understandably, the control module can be multiple controllers that are electrically connected to each other and interact with each other, or it can be a single controller that enables multiple controls.

[0045] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0046] The above is a description of the technical solution provided by this utility model. For those skilled in the art, based on the idea of ​​the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
