Technical Field

[0001] This utility model belongs to the field of dispensing equipment, and in particular relates to a glue-wiping device. Background Technology

[0002] Dispensing equipment is an automated device that precisely applies a specific amount of liquid material (such as glue, paint, silicone, grease, epoxy resin, etc.) to a target location. However, problems such as excessive / insufficient dispensing, misalignment, bubbles, stringing, leakage, and dripping can easily occur during the dispensing process. Therefore, in practice, it is usually necessary to wipe the dispensing needle clean. Traditional methods typically involve manual wiping, which is inefficient, time-consuming, and labor-intensive. Utility Model Content

[0003] The technical objective of this utility model is to provide a glue-wiping device, which aims to solve the technical problem that the needles of glue-wiping equipment are usually wiped manually, which is inefficient and time-consuming.

[0004] To solve the above-mentioned technical problems, this utility model is implemented as follows: a glue-wiping device for wiping the needle of a glue-dispensing device. The glue-wiping device includes a base frame, a ribbon, a transmission module, a clamping module, a control module, and a sensing module. The transmission module and the clamping module are assembled on the base frame. The ribbon has two fixed ends and a cleaning part located between the two fixed ends. The transmission module includes a driving wheel, a driven wheel, and a first driving member. The first driving member is electrically connected to the control module and connected to the driving wheel. The needle is orthogonally arranged with the ribbon, and the two fixed ends are respectively wound around the driving wheel and the driven wheel. The clamping module is connected to the control module to drive the cleaning part to conform to the needle. The sensing module includes a sensing shaft rotatably connected to the base frame and a sensor disposed on the sensing shaft. The ribbon is disposed on the outer periphery of the sensing shaft to drive the sensing shaft to rotate. The sensor is used to detect the rotation angle of the sensing shaft. The sensor is electrically connected to the control module.

[0005] Furthermore, in some embodiments, the adhesive application device further includes three auxiliary shafts, which are rotatably connected to the base frame and parallel to the sensing shaft. The ribbon is connected from the driving wheel to the driven wheel through the sensing shaft and each of the auxiliary shafts. The three auxiliary shafts are arranged in a triangular array at intervals so that the ribbon passing through the auxiliary shafts forms a cavity, which is used to place the needle.

[0006] Furthermore, in some embodiments, the adhesive applicator further includes a receiving cup, which is positioned directly opposite the cavity along a direction orthogonal to the ribbon, and the opening of the receiving cup communicates with the cavity.

[0007] Furthermore, in some embodiments, the adhesive application device further includes a clamping module, which includes two push blocks and a second driving member, wherein one push block abuts against one side of the ribbon away from the cavity, and the other push block abuts against the other side of the ribbon away from the cavity, and the second driving member is electrically connected to the control module; and the second driving member is connected to the push blocks to bring the two push blocks closer to each other or separate them from each other.

[0008] Furthermore, in some embodiments, the adhesive application device further includes two buffers, one of which is disposed on the side of the pusher block away from the ribbon, and the other buffer is disposed on the side of the other pusher block away from the ribbon.

[0009] Furthermore, in some embodiments, the pusher is provided with a mounting groove having an opening facing the ribbon, and the buffer is fitted into the mounting groove and protrudes from the opening.

[0010] Furthermore, in some embodiments, the adhesive application device further includes a cleaning module disposed near the fixed end of the cleaning section, for spraying cleaning agent onto the ribbon.

[0011] Furthermore, in some embodiments, the cleaning module includes a cleaning agent nozzle, the axis of which is arranged parallel to the sensing axis, and the cleaning agent nozzle is fixedly mounted on the base frame.

[0012] Furthermore, in some embodiments, the cleaning module further includes a solenoid valve for controlling the opening or closing of the cleaning agent nozzle, the solenoid valve being electrically connected to the control module.

[0013] Furthermore, in some embodiments, the adhesive application device further includes a damper, which is coaxially arranged with the driven wheel.

[0014] The adhesive application device in this invention has the following advantages compared with related technologies:

[0015] In this invention, the control module activates the first driving component, which in turn controls the rotation of the drive wheel. The two fixed ends of the ribbon are wound around the drive wheel and the driven wheel, respectively. This causes the drive wheel to move the ribbon, which in turn drives the driven wheel to rotate, thus cleaning the needle tip and automating the adhesive application process. Furthermore, this invention includes a sensing module. As the ribbon moves, it drives a sensing shaft to rotate. The sensor detects the rotation angle of the sensing shaft and transmits it to the control module, allowing the control module to determine the length of the ribbon's movement. This precise control of the ribbon's movement prevents the fixed ends from completely detaching from the drive wheel. Attached Figure Description

[0023] Please see Figures 1 to 2 This utility model provides an adhesive wiping device for wiping the needle of an adhesive dispensing device. The adhesive wiping device includes a base frame 1, a ribbon 2, a transmission module, a clamping module, a control module, and a sensing module. The transmission module and the clamping module are assembled on the base frame 1. The ribbon 2 has two fixed ends and a cleaning part located between the two fixed ends. The transmission module includes a driving wheel 3, a driven wheel 4, and a first driving member 5. The first driving member 5 is electrically connected to the control module and connected to the driving wheel 3. The needle is orthogonally arranged with the ribbon 2, and the two fixed ends are respectively wound around the driving wheel 3 and the driven wheel 4. The clamping module is connected to the control module to drive the cleaning part to adhere to the needle. The sensing module includes a sensing shaft 6 rotatably connected to the base frame 1 and a sensor 7 disposed on the sensing shaft 6. The ribbon 2 is disposed on the outer periphery of the sensing shaft 6 to drive the sensing shaft 6 to rotate. The sensor 7 is used to detect the rotation angle of the sensing shaft 6. The sensor 7 is electrically connected to the control module.

[0024] In this embodiment of the invention, the control module controls the first driving component 5 to open, causing the first driving component 5 to control the rotation of the driving wheel 3. The two fixed ends of the ribbon 2 are respectively wound around the driving wheel 3 and the driven wheel 4, so that the driving wheel 3 drives the ribbon 2 to move and the ribbon 2 drives the driven wheel 4 to rotate. In this way, the needle tip can be cleaned, realizing an automated glue-wiping process. In addition, this embodiment of the invention also includes a sensing module. During the movement of the ribbon 2, it can drive the sensing shaft 6 to rotate. The sensor 7 can detect the rotation angle of the sensing shaft 6 and transmit it to the control module, so that the control module can obtain the moving length of the ribbon 2. This allows for precise control of the moving length of the ribbon 2, preventing the transmission module from continuing to operate even after the ribbon 2 has been used up.

[0025] 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.

[0026] Understandably, in some embodiments, the adhesive application device also includes a control panel 16, so that the user can control whether the first drive unit 5 is turned on by operating the control panel 16.

[0027] For example, the first driving component 5 can be a motor or a cylinder, etc.

[0028] In some specific embodiments, the driving wheel 3 and the driven wheel 4 can be fixedly mounted to the base frame 1 by a knob.

[0029] Furthermore, in some embodiments, the adhesive application device further includes three auxiliary shafts 8, which are rotatably connected to the base frame 1 and parallel to the sensing shaft 6. The ribbon 2 is driven by the driving wheel 3 and connected to the driven wheel 4 through the sensing shaft 6 and each of the auxiliary shafts 8. The three auxiliary shafts 8 are arranged in a triangular array at intervals so that the ribbon 2 passing through the auxiliary shafts 8 forms a cavity, which is used to set the needle.

[0030] Specifically, one fixed end of the ribbon 2 is wound around the driving wheel 3 multiple times. The middle portion of the ribbon 2 then passes through the sensing shaft 6 and the auxiliary shaft 8, and finally the remaining ribbon 2 is wound around the driven wheel 4. The auxiliary shaft 8 keeps the ribbon 2 straight and prevents it from loosening. Furthermore, by arranging the three auxiliary shafts 8 in a triangular array, the ribbons 2 passing through these three shafts sequentially form a cavity, allowing the needle to be placed inside. This ensures that the outer periphery of the needle contacts the ribbon 2, enabling the ribbon 2 to more effectively wipe away the needle. Additionally, as the ribbon 2 moves, it drives the auxiliary shaft 8 to rotate, ensuring synchronized movement between the ribbon 2 and the auxiliary shaft 8. This further enhances the movement and wiping effect of the ribbon 2, preventing it from loosening.

[0031] Understandably, the number of auxiliary shafts 8 in this embodiment of the present invention is not limited and can be greater than or equal to 3.

[0032] It should be noted that in some embodiments, the ribbon 2 can move along the winding path from the driven wheel 4 to the driven wheel 3. In this case, during the erasing process, the ribbon 2 accumulates more and more on the driven wheel 3 and less and less on the driven wheel 4. After erasing is completed, the ribbon 2 moves in the opposite direction to retract it. In some embodiments, the ribbon 2 can move along the winding path from the driven wheel 3 to the driven wheel 4. In this case, during the erasing process, the ribbon 2 accumulates more and more on the driven wheel 3 and more on the driven wheel 4. After erasing is completed, the ribbon 2 moves in the opposite direction to retract it.

[0033] Furthermore, in some embodiments, the adhesive applicator further includes a receiving cup 9, which is positioned directly opposite the cavity along a direction orthogonal to the ribbon 2, and the opening of the receiving cup 9 communicates with the cavity.

[0034] Specifically, with the ribbon 2 on top, a receiving cup 9 can be placed below the cavity so that the wiped-off glue can fall into the receiving cup 9.

[0035] Furthermore, in some embodiments, the adhesive application device further includes a clamping module, which includes two push blocks 10 and a second drive member 11, wherein one push block 10 abuts against one side of the ribbon 2 away from the cavity, and the other push block 10 abuts against the other side of the ribbon 2 away from the cavity, and the second drive member 11 is electrically connected to the control module; and the second drive member 11 is connected to the push blocks 10 so that the two push blocks 10 are brought closer to each other or separated from each other.

[0036] Specifically, two push blocks 10 are respectively provided on both sides of the ribbon 2 away from the cavity. The control module can control the second drive component 11, so that the second drive component 11 can control the push blocks 10 to move closer or further apart. In this way, during the wiping process, the needle can be placed in the cavity first, and then the two push blocks 10 can be driven to move closer together, so that the ribbon 2 can contact the needle. Then, by controlling the movement of the ribbon 2, the glue on the needle can be cleaned. After cleaning is completed, the control module first controls the first drive component 5 to stop the movement of the ribbon 2; then controls the second drive component 11, which controls the two push blocks 10 to move further apart, so that the ribbon 2 is away from the needle. The cleaned needle can then be removed from the glue-wiping device for glue dispensing.

[0037] For example, the second drive component 11 can be a cylinder or a motor, etc.

[0038] Furthermore, in some embodiments, the adhesive application device further includes two buffer members 12, one buffer member 12 being disposed on the side of the push block 10 facing away from the ribbon 2, and the other buffer member 12 being disposed on the side of the other push block 10 facing away from the ribbon 2. By providing the buffer member 12 between the ribbon 2 and the push block 10, the two push blocks 10 can be cushioned by the buffer member 12 during the process of approaching and moving away from each other; at the same time, the ribbon 2 can also be cushioned during the pulling process.

[0039] For example, the buffer 12 can be a sponge or a flexible silicone part, etc.

[0040] Furthermore, in some embodiments, the push block 10 is provided with a mounting groove having an opening facing the ribbon 2, and the buffer member 12 is mounted in the mounting groove and protrudes from the opening. The mounting groove allows the buffer member 12 to be stably mounted to the push block 10. The buffer member 12 partially protrudes from the mounting groove, allowing it to contact the ribbon 2 and thus providing a cushioning effect.

[0041] Furthermore, in some embodiments, the adhesive removal device further includes a cleaning module disposed near the fixed end of the cleaning section, for spraying cleaning agent onto the ribbon 2. By disposing of the cleaning module near the fixed end of the cleaning section, the ribbon 2 can be sprayed with cleaning agent before passing through the needle, thereby more thoroughly cleaning the dried adhesive on the needle.

[0042] For example, the cleaning agent can be alcohol.

[0043] Furthermore, in some embodiments, the cleaning module includes a cleaning agent nozzle 13, the axis of which is parallel to the sensing shaft 6, and the cleaning agent nozzle 13 is fixedly mounted on the base frame 1. Cleaning agent can be sprayed through the cleaning agent nozzle 13. In some embodiments, the cleaning agent nozzle 13 can directly contact the ribbon 2, allowing the ribbon 2 to be soaked in cleaning agent. In some embodiments, the cleaning agent nozzle 13 can be spaced apart from the ribbon 2, but the liquid outlet of the cleaning agent nozzle 13 faces the ribbon 2, so that the cleaning agent reaches the ribbon 2 directly after being sprayed.

[0044] Furthermore, in some embodiments, the cleaning module also includes a solenoid valve 14 for controlling the opening or closing of the cleaning agent nozzle 13, the solenoid valve 14 being electrically connected to the control module. The control module can control whether the cleaning agent nozzle 13 sprays cleaning agent by controlling the opening or closing of the solenoid valve 14.

[0045] Furthermore, in some embodiments, the adhesive application device also includes a damper 15, which is coaxially arranged with the driven wheel 4. By providing the damper 15 at the driven wheel 4, the ribbon 2 is less likely to loosen during the pulling process.

[0046] 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 needle to the cavity, the control module controls the solenoid valve 14 to open, and simultaneously controls the first drive module. The first drive module drives the drive wheel 3 to rotate, causing the ribbon 2 to move. Then, the second drive module is controlled to bring the two push blocks 10 closer together, so that the needle is clamped between the ribbons 2, and the ribbon 2 contacts the needle to clean the needle. After the adhesive application is completed, the control module controls the first drive module to stop the ribbon 2 from moving; at the same time, it controls the second drive module to move the two push blocks 10 away from each other; then the dispensing equipment can move the needle out of the cavity. Finally, the control system can control the first drive module to rotate the drive wheel 3 in the opposite direction, and the ribbon 2 moves back, thus retracting the ribbon 2.

[0047] 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.

[0048] 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.

[0049] The above is a description of the technical solution provided by this utility model. For those skilled in the art, based on the ideas 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.
