[0002] In industrial production, the adhesive application process is an indispensable part of the manufacturing of many products, and its quality directly affects the product's performance, appearance, and lifespan. For example, in industries such as electronic component packaging, wood processing, and automotive interior manufacturing, precise and uniform adhesive application plays a crucial role in ensuring the product's sealing, bonding strength, and overall quality.
[0003] However, traditional glue application methods mainly include manual application and simple mechanical glue application equipment. Manual glue application relies on the skills and experience of operators, which is not only labor-intensive and inefficient, but also makes it difficult to guarantee the uniformity and consistency of glue application. There may be significant differences between different batches of products, making it difficult to meet the requirements of product quality stability for large-scale industrial production.
[0004] While existing mechanical adhesive application equipment has improved adhesive application efficiency to some extent, it still has many shortcomings. Some equipment only has basic adhesive supply functions, applying adhesive directly to the workpiece through a single outlet. This method makes it difficult to control the flow and distribution of adhesive, easily leading to adhesive accumulation or uneven application, which affects product quality. Utility Model Content

The lifting device cooperates with the mounting base to place the mounting base in the closed state during lifting and in the open state during lowering, so as to internally support and secure the workpiece to be coated.
[0008] In one specific embodiment, the mounting base includes a plurality of protrusions, which are arranged in a circular array at intervals, and the plurality of protrusions close inward in the closed state and open outward in the open state. A cavity is defined between the inner sides of the plurality of protrusions, and the end of the lifting device faces the cavity for passing through the cavity and squeezing the plurality of protrusions outward during descent, and for closing the plurality of protrusions inward away from the cavity during ascent.
[0009] In one specific embodiment, the outer side of the protrusion is provided with a mounting groove, and the mounting grooves of the plurality of protrusions cooperate to install the workpiece to be coated in the closed state.
[0010] In one specific embodiment, the glue supply device further includes a glue storage tank and a delivery pipe, the glue storage tank being disposed above the glue outlet, and the delivery pipe being connected to the glue storage tank and the glue outlet respectively.
[0011] In one specific embodiment, the impregnation device further includes a base, a first drive member, and a glue storage box. The glue storage box is disposed on the base and located below the impregnation roller, and is used to receive the glue material falling from the impregnation roller. The first drive member is disposed on the base and is drivenly connected to the impregnation roller, and is used to make the impregnation roller roll.
[0012] In one specific embodiment, the glue storage box has an open end facing the dip roller, the glue storage box is provided with a cover plate that seals the open end, a portion of the dip roller is placed inside the glue storage box, and the remaining portion of the glue storage box extends out of the cover plate.
[0013] In one specific embodiment, the frame is provided with a CNC system and a moving module. The moving module platform is connected to the gluing device. The CNC system is used to make the gluing device move along a curved trajectory and make the gluing axis of the gluing device move at a specific speed and feed to roll the adhesive onto the workpiece to be coated.
[0014] In one specific embodiment, the gluing device includes a gluing base, a gluing shaft, and a second driving member. The gluing shaft and the second driving member are disposed on the gluing base, and the gluing shaft is configured to be driven to rotate by the second driving member.
[0015] In one specific embodiment, the surfaces of the coating shaft and the dip roller both have microporous structures for absorbing adhesive.

[0020] Various embodiments of this application will be described more fully below. This application may have various embodiments, and adjustments and changes may be made therein. However, it should be understood that there is no intention to limit the various embodiments of this application to the specific embodiments disclosed herein, but rather this application should be understood to cover all adjustments, equivalents, and / or alternatives falling within the spirit and scope of the various embodiments of this application.
[0021] In the following, the terms “comprising” or “may include” as used in the various embodiments of this application indicate the presence of the disclosed functions, operations, or elements, and do not limit the addition of one or more functions, operations, or elements. Furthermore, as used in the various embodiments of this application, the terms “comprising,” “having,” and their cognates are intended only to indicate a particular feature, number, step, operation, element, component, or combination of the foregoing, and should not be construed as primarily excluding the presence of one or more other features, numbers, steps, operations, elements, components, or combinations of the foregoing, or the possibility of adding one or more combinations of features, numbers, steps, operations, elements, components, or combinations of the foregoing.

For example, the expression "A or B" or "at least one of A and / or B" may include A, may include B, or may include both A and B.
[0023] The terms used in the various embodiments of this application (such as "first," "second," etc.) may modify various constituent elements in the various embodiments, but do not limit the corresponding constituent elements. For example, the above terms do not limit the order and / or importance of the elements. The above terms are only used for the purpose of distinguishing one element from other elements. For example, a first user device and a second user device refer to different user devices, although both are user devices. For example, without departing from the scope of the various embodiments of this application, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.
[0024] like Figure 1 As shown, this application relates to the field of adhesive coating technology, specifically to a CNC adhesive coating machine, including a frame 6 and a workpiece clamp 1, an adhesive supply device 2, an adhesive dipping device 3, and an adhesive application device 4 mounted on the frame 6. The workpiece clamp 1 is used to clamp the workpiece 7 to be coated; the end of the adhesive supply device 2 has an adhesive outlet head 21 for discharging adhesive material; the adhesive dipping device 3 has a rollable adhesive dipping roller 33, and the adhesive outlet head 21 abuts against the adhesive dipping roller 33 to discharge adhesive material so that the adhesive dipping roller 33 is fully wetted; the adhesive dipping device 3 also has a leveling roller 35, which abuts against and squeezes the adhesive dipping roller 33, and the leveling roller 35 is located parallel to the adhesive outlet head 21 along the rolling direction of the adhesive dipping roller 33, for evenly spreading the adhesive material on the adhesive dipping roller 33; the adhesive application device 4 is movable relative to the frame 6, for moving to the adhesive dipping roller 33 to obtain uniform adhesive material on the adhesive dipping roller 33, and moving to the workpiece clamp 1 to apply the adhesive material to the workpiece 7 to be coated.
[0025] The CNC glue applicator of this application integrates a workpiece fixture 1, a glue supply device 2, a glue dipping device 3, and a glue application device 4 through a frame 6. Through the clear division of labor and mutual cooperation among these devices, the entire process from workpiece fixing, glue supply, glue dipping and even application to glue application is fully automated, greatly improving glue application efficiency, reducing manual intervention, and lowering labor intensity. Furthermore, the positional arrangement of the glue dipping roller 33, the glue outlet 21, and the even application roller 35 improves the stability and consistency of the glue application process, thereby enhancing the glue application quality. Specifically, the glue outlet 21 at the end of the glue supply device 2 abuts against the glue dipping roller 33 to output glue material. This not only allows for precise control of the glue output, ensuring the glue dipping roller 33 is fully wetted and avoiding glue waste, but also ensures that the surface of the glue dipping roller 33 always has an appropriate and uniform amount of glue. The even application roller 35 abuts against and squeezes the glue dipping roller 33, and is located parallel to the glue outlet 21 along the rolling direction of the glue dipping roller 33, enabling timely and even spreading of the glue material during the rolling process of the glue dipping roller 33. This further improves the uniformity of the adhesive material obtained by the adhesive application device 4.
[0026] like Figure 4-6 As shown, the workpiece fixture 1 includes a mounting base 11 and a lifting device 12. The mounting base 11 has a closed state and an open state. When the mounting base 11 is in the closed state, the workpiece 7 to be coated is mounted on it. When the mounting base 11 is in the open state, the workpiece 7 to be coated is clamped. The lifting device 12 cooperates with the mounting base 11 to keep the mounting base in the closed state during lifting to release the workpiece to be coated, and to keep the mounting base in the open state during lowering to support the workpiece to be coated.
[0027] The workpiece fixture 1 of this application adopts a structure in which a mounting base 11 and a lifting device 12 cooperate. The mounting base 11 has two states: closed and open. In the closed state, the workpiece 7 to be coated is installed; in the open state, the workpiece is clamped, making the installation and removal of the workpiece more convenient and quick, and improving production efficiency. At the same time, because the mounting base 11 has a fixed inner frame for the workpiece to be coated, it can accurately position the workpiece to be coated. With the addition of the internal support mechanism, the cooperation between the lifting device 12 and the mounting base 11 can precisely control the state transition of the mounting base 11, ensuring that the workpiece is stably clamped during the glue coating process, avoiding the problem of uneven glue coating caused by workpiece shaking, and improving the glue coating quality.
[0028] like Figure 4-6 As shown in Figure 8, the mounting base 11 includes a plurality of protrusions 111, which are arranged in a circular array at intervals. The protrusions 111 close inward in a closed state and open outward in an open state. A cavity 112 is defined between the inner sides of the plurality of protrusions 111. The end of the lifting device has an action part 121 facing the cavity 112. The action part 121 is used to pass through the cavity 112 and squeeze the plurality of protrusions 111 to open outward and secure the workpiece to be coated when descending, and to move away from the cavity 112 when rising and cause the plurality of protrusions 111 to close inward and release the workpiece to be coated.
[0029] The action part 121 has a shape that is wider at the top and narrower at the bottom. When the action part 121 descends, it passes through the cavity 112 and squeezes multiple protrusions 111 to open outward and fasten the workpiece to be coated. When the action part 121 rises, it moves away from the cavity 112 and causes the multiple protrusions 111 to close inward and loosen the workpiece to be coated.
[0030] The mounting base 11 of this application includes a plurality of protrusions 111 arranged in a circular array at intervals. These protrusions close inwards in the closed state and open outwards in the open state. This structure can adaptively adjust according to the shape and size of the workpiece, better conforming to the workpiece surface and providing a more uniform clamping force, ensuring the stability of the workpiece during the adhesive application process. The cavity defined inside the plurality of protrusions 111 and the fitting design between the end of the lifting device 12 and the cavity enable the lifting device 12 to accurately apply force, achieving precise opening and closing of the mounting base 11, further improving the reliability and ease of operation of the workpiece clamp 1.
[0031] like Figure 6 As shown, the outer side of the protrusion 111 is provided with a mounting groove 1111, and the mounting grooves 1111 of the multiple protrusions 111 cooperate to install the workpiece 7 to be coated in the closed state.
[0032] This application utilizes mounting grooves 1111 on the outer side of the protrusions 111. The mounting grooves 1111 of multiple protrusions 111 cooperate with each other, allowing the workpiece 7 to be coated to be installed in the closed state. This enables the workpiece to be quickly and accurately placed in the correct position during installation, reducing installation time and errors. Simultaneously, the cooperation between the mounting grooves 1111 and the workpiece also provides guidance and fixation, preventing displacement of the workpiece during adhesive application and ensuring the accuracy and quality of the adhesive application.
[0033] like Figure 4 As shown, the glue supply device 2 also includes a glue storage tank 23 and a delivery pipe 22. The glue storage tank 23 is located above the glue outlet 21, and the delivery pipe 22 is connected to the glue storage tank 23 and the glue outlet 21 respectively.
[0034] This application uses a glue supply device 2 with a glue storage tank 23 and a delivery pipe 22. The glue storage tank 23 is positioned above the glue outlet 21, and the delivery pipe 22 connects both the glue storage tank 23 and the glue outlet 21. This allows the glue to flow naturally towards the glue outlet 21 using gravity, reducing energy consumption while ensuring continuous and stable glue supply. The glue storage tank 23 can store a certain amount of glue, reducing the frequency of glue additions and improving production efficiency. The selection and layout of the delivery pipe 22 ensures that the glue is not contaminated or leaked during transport, guaranteeing the quality of the glue.
[0035] A closable valve is installed at the connection between the glue storage tank 23 and the delivery pipe 22. The opening degree can be precisely adjusted through the valve, thereby achieving precise control over the amount of glue flowing out. During the glue application process, different workpieces or different glue application areas may have different requirements for the amount of glue used. By adjusting the valve, it can be ensured that the appropriate amount of glue is provided each time glue is applied, avoiding glue waste and ensuring the consistency of glue application quality.
[0036] like Figure 3 , 5 As shown, the impregnation device 3 also includes a base 31, a first drive member 32, and an adhesive storage box 34. The adhesive storage box 34 is disposed on the base 31 and located below the impregnation roller 33, and is used to receive the adhesive material falling from the impregnation roller 33. The first drive member 32 is disposed on the base 31 and is drivenly connected to the impregnation roller 33, and is used to make the impregnation roller 33 roll.
[0037] This application provides stable support for other components of the dipping device 3 via the base 31, ensuring the installation accuracy and operational stability of the dipping roller 33 and the drive component. The first drive component 32 is driven by the dipping roller 33, enabling precise control of the rolling speed and direction of the dipping roller 33 to meet the requirements of different coating processes. The glue storage box 34 can collect the glue falling from the dipping roller 33 in a timely manner, avoiding glue waste and environmental pollution, while facilitating the recycling and reuse of the glue.
[0038] like Figure 3 , 5 As shown, the glue storage box 34 has an open end 341 facing the glue dipping roller 33. The glue storage box 34 is provided with a cover plate 36, which blocks the open end 341. A part of the glue dipping roller 33 is placed inside the glue storage box 34, and the rest of the glue storage box 34 extends out of the cover plate 36.
[0039] The glue storage box 34 of this application has an open end 341 facing the glue dipping roller 33. The open end 341 is sealed by a cover plate 36. A part of the glue dipping roller 33 is placed inside the glue storage box 34, and the rest extends out of the cover plate 36. This ensures that the glue dipping roller 33 can fully contact the glue material in the glue storage box 34 to replenish the glue material. At the same time, the cover plate 36 prevents the evaporation of the glue material and the entry of external impurities, maintaining the purity and stability of the glue material in the glue storage box 34, which is beneficial to improving the glue coating quality.
[0040] like Figure 1 , 4As shown, the frame 6 is equipped with a CNC system and a moving module platform 5. The moving module platform 5 is connected to the gluing device 4, which is used to move the gluing device 4 relative to the frame 6. The CNC system is used to move the gluing device 4 according to a trajectory curve and to roll the glue application axis of the gluing device 4 to apply the glue to the workpiece to be coated. The CNC system has a pre-stored NC program that controls the gluing device 4 to move according to the trajectory curve. The G code and M code of the pre-stored NC program drive the gluing device 4 to move according to the trajectory curve, thereby making the glue better and more evenly applied to the workpiece to be coated.
[0041] This application connects the gluing device 4 to a movable module platform 5 mounted on the frame 6, enabling the gluing device 4 to move relative to the frame 6. The movable module platform 5 provides the gluing device 4 with flexible movement, allowing for precise adjustment of its position according to the workpiece's location and gluing requirements. This enables multi-point, multi-position gluing operations, improving the adaptability and flexibility of the gluing process. It can meet the gluing needs of workpieces of different shapes and sizes, expanding the equipment's application range.
[0042] Specifically, the mobile module platform 5 includes a support 51, a first moving device 52, and a second moving device 53; the support 51 extends along the height direction of the frame 6; the first moving device 52 is mounted on the support 51 and configured to move along the height direction of the frame 6; the second moving device 53 is disposed on the first moving device 52 and configured to move along the length direction or the width direction of the frame 6; the gluing device 4 is disposed on the second moving device 53 and cooperates with the first moving device 52 and the second moving device 53 to move along the height and length direction or along the height and width direction of the frame 6.
[0043] Specifically, the first moving device 52 and the support 51 have a first guide structure for moving the first moving device 52 along the extension direction of the support 51, so that the first moving device 52 moves along the height direction of the frame 611. The first moving device 52 also includes a first lead screw, a first nut, and a first stepper motor. The first lead screw is vertically mounted on the support 51 along the height direction of the frame 611, and the first nut is sleeved on the first lead screw and connected to the first moving device 52. When the first stepper motor rotates, it drives the first lead screw to rotate. Due to the threaded engagement between the first nut and the first lead screw, the first nut will move linearly along the first lead screw, thereby driving the first moving device 52 to move.
[0044] Similarly, a second guide structure is provided between the second moving device 53 and the first moving device 52 to allow the second moving device 53 to move along the first moving device 52, thereby moving the second moving device 53 along the length or width direction of the frame 611. The second moving device 53 also includes a second lead screw, a second nut, and a second stepper motor. The second lead screw is installed along the extension direction of the first moving device 52 (i.e., the length or width direction of the frame 611), and the second nut is sleeved on the second lead screw and connected to the second moving device 53. When the second stepper motor rotates, it drives the second lead screw to rotate. Due to the threaded engagement between the second nut and the second lead screw, the second nut will move linearly along the second lead screw, thereby driving the second moving device 53 to move.
[0045] The first guide structure and the second guide structure are concave-convex structures.
[0046] like Figure 7 As shown, the gluing device 4 includes a gluing base 41, a gluing shaft 42, and a second drive member 43. The gluing shaft 42 and the second drive member 43 are disposed on the gluing base 41, and the gluing shaft 42 is configured to be driven by the second drive member 43 to rotate.
[0047] The adhesive applicator 41 of this application provides a stable mounting base for the adhesive applicator 42 and the drive component, ensuring the stability and accuracy of the adhesive applicator 42 during rotation. The second drive component 43 can precisely control the rotation speed and direction of the adhesive applicator 42, enabling the adhesive applicator 42 to uniformly apply adhesive to the workpiece, thereby improving the quality and efficiency of adhesive application.
[0048] The surfaces of the coating shaft 42 and the dipping roller 33 both have microporous structures for absorbing adhesive material (not shown in the figure).
[0049] The microporous structure of this application increases the contact area between the adhesive material and the shaft surface, improving the adhesion of the adhesive material and allowing it to be distributed more evenly on the shaft surface. During the impregnation process, the microporous structure can better absorb and store the adhesive material, ensuring that there is always sufficient adhesive material supply on the surface of the impregnation roller 33; during the coating process, the microporous structure enables the adhesive material to be transferred more evenly to the workpiece, improving the uniformity and quality of coating and reducing adhesive material waste.
[0050] In this embodiment, the adhesive material includes glue.
