The gluing device is movably mounted on the frame and is used to move to contact the first roller to obtain uniform glue on the first roller, and to move to the tooling fixture to apply the glue to the workpiece to be coated.

[0006] In one specific embodiment, the processing platform includes a processing base, a first limiting member, and a second limiting member. The first limiting member and the second limiting member are movably disposed on the processing base. The first limiting member and the second limiting member are disposed facing each other and far apart from each other, and are used to contact the two opposite inner sidewalls of the workpiece to be coated to limit the position of the workpiece to be coated.

[0007] In one specific embodiment, the first roller includes a power roller, and the second roller includes a follower roller. The power roller is drivenly connected to the follower roller to make the follower roller rotate. Alternatively, the first roller may include a first powered roller, and the second roller may include a second powered roller, with the first powered roller and the second powered roller rotating in opposite directions.

[0008] In one specific embodiment, the base is provided with a cover plate that covers the second roller; the cover plate has a scraping part that extends from the second roller toward the first roller and abuts against the end of the second roller and the bottom side of the first roller, respectively.

[0009] In one specific embodiment, the radius of the first roller is greater than the radius of the second roller, the central axis of the second roller is in the same plane as the central axis of the first roller and does not intersect, and the distance between the central axis of the second roller and the central axis of the first roller is equal to the sum of the radii of the first roller and the radii of the second roller.

[0010] In one specific embodiment, the ratio of the radius of the first roller to the radius of the second roller is between 1.2 and 4.

[0011] In one specific embodiment, the gluing device has a support plate, on which a gluing shaft and a rotating motor are provided, and the gluing shaft is configured to be driven by the rotating motor.

[0012] In one specific embodiment, a fine-tuning mechanism is also included, which is connected to the machining platform and is used for five-axis adjustment of the position of the machining platform on the frame.

[0013] In one specific embodiment, the frame includes a substrate and a moving platform.

[0015] This application has at least the following beneficial effects: This application relates to the field of adhesive coating technology, specifically proposing an adhesive coating machine, comprising: a frame; a processing platform mounted on the frame for mounting the workpiece to be coated; an adhesive dipping device including a base, a first roller, and a second roller; the base being mounted on the frame and having a supply groove for holding adhesive; the first roller being mounted on the base and at least partially located within the supply groove for dipping in adhesive during rolling; and the second roller being mounted on the base and located above the supply groove; the second roller abutting against and pressing against the first roller to evenly spread the adhesive on the first roller; and an adhesive application device movably mounted on the frame for moving to contact the first roller to obtain uniform adhesive on the first roller, and moving to a tooling fixture to apply the adhesive to the workpiece to be coated. This application automates the adhesive coating process through the cooperation between the processing platform, the adhesive dipping device, and the adhesive application device, improving coating efficiency. Furthermore, the cooperation between the base of the adhesive dipping device and the first and second rollers ensures more uniform adhesive application to the workpiece, thereby improving coating quality. Specifically, by setting a supply groove in the base, the first roller is partially immersed in it, which can continuously and stably obtain glue. Compared with traditional glue supply methods, this avoids problems such as glue application interruption or uneven glue amount caused by unstable glue supply, ensuring the continuity of the glue application process. Furthermore, by the second roller abutting and pressing against the first roller, the relative rolling and pressing action of the two rollers can more evenly spread the glue on the first roller, making the glue obtained by the glue application device more uniform, improving the glue application quality, and reducing problems such as weak adhesion and poor sealing caused by uneven glue distribution.

Detailed Implementation

[0019] 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.

[0020] 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.

[0021] like Figure 1-8As shown, this application relates to the field of adhesive coating technology, specifically proposing an adhesive coating machine, including: a frame 1, a processing platform 2, which is mounted on the frame 1 for mounting the workpiece 6 to be coated; an adhesive dipping device 3, including a base 31, a first roller 32, and a second roller 33, the base 31 being mounted on the frame 1 and having a supply groove 311 for placing adhesive, the first roller 32 being mounted on the base 31 and at least partly located within the supply groove 311 for dipping into adhesive during rolling; the second roller 33 being mounted on the base 31 and located above the supply groove 311; the second roller 33 abutting against and pressing the first roller 32 for evenly spreading the adhesive on the first roller 32; and an adhesive application device 4, movably mounted on the frame 1, for moving to contact the first roller 32 to obtain uniform adhesive on the first roller 32, and moving to a tooling fixture to apply the adhesive to the workpiece 6 to be coated.

[0022] This application automates the glue application process by cooperating with the processing platform 2, the glue dipping device 3, and the glue application device 4, thereby improving glue application efficiency. Furthermore, the cooperation between the base 31, the first roller 32, and the second roller 33 of the glue dipping device 3 ensures more uniform glue application to the workpiece 6, thus improving the coating quality. Specifically, by providing a supply groove 311 in the base 31, the first roller 32 is partially immersed in it, allowing for a continuous and stable supply of glue. Compared to traditional glue supply methods, this avoids interruptions or uneven glue application caused by unstable glue supply, ensuring the continuity of the glue application process. Moreover, the second roller 33 abuts against and presses against the first roller 32. The relative rolling and pressing action of the two rollers allows for more even distribution of glue on the first roller 32, resulting in more uniform glue application by the glue application device 4, improving the coating quality, and reducing problems such as weak adhesion and poor sealing caused by uneven glue distribution.

[0023] like Figure 1-8 As shown, the processing platform 2 includes a processing base 23, a first limiting member 21 and a second limiting member 22. The first limiting member 21 and the second limiting member 22 are movably disposed on the processing base 23. The first limiting member 21 and the second limiting member 22 are disposed facing each other and far apart from each other, and are used to contact the two opposite inner sidewalls of the workpiece 6 to be coated in order to limit the position of the workpiece 6 to be coated.

[0024] This application uses a movable first limiting member 21 and a second limiting member 22 on the processing base 23 to flexibly adjust according to the different shapes and sizes of the workpiece 6 to be coated. By contacting the two opposite inner sidewalls of the workpiece, the position of the workpiece is precisely limited, ensuring that the workpiece is in the correct position when applying glue, thus improving the accuracy and consistency of glue application.

[0025] like Figure 1-8As shown, the first roller 32 includes a power roller, and the second roller 33 includes a follower roller. The power roller and the follower roller are connected in a transmission connection to make the follower roller rotate; or the first roller 32 includes a first power roller, and the second roller 33 includes a second power roller, with the first power roller and the second power roller rotating in opposite directions.

[0026] This application provides two roller drive methods: one is that the power roller drives the follower roller to rotate, which is simple in structure and easy to control; the other is that the first power roller and the second power roller are driven independently and in opposite directions, which can meet the diverse requirements of the adhesive coating process.

[0027] In this embodiment, the first roller 32 includes a driven roller, and the second roller 33 includes a follower roller. The driven roller and the follower roller are connected by a drive mechanism to rotate the follower roller. A reasonable roller drive method can ensure that the rollers rotate at an appropriate speed, allowing the adhesive to be applied evenly and quickly to the workpiece, improving the adhesive application efficiency and shortening the production cycle. Specifically, the driven roller consists of two parts: a drive component 322 and a roller component 321. The roller component 322 is driven to roll by the drive component 322.

[0028] like Figure 1-8 As shown, a cover plate 312 is provided on the base 31, covering the second roller 33. The cover plate 312 has a scraping part 3121, which extends from the second roller 33 toward the first roller 32 and abuts against the end of the second roller 33 and the bottom side of the first roller 32, respectively. The cover plate 312 of this application can protect the second roller 33 on the one hand, and the scraping part 3121 of the cover plate 312 abuts against the bottom side of the second roller 33 and the first roller 32 on the other hand. Its purpose is to scrape the ink on the side of the first roller 32 and the second roller 33, preventing the ink in the oil tank from overflowing above the intersection of the first roller 32 and the second roller 33 as the first roller 32 rotates.

[0029] In one embodiment, the scraper part 3121 is a silicone scraper.

[0030] like Figure 7 As shown, the radius R1 of the first roller 32 is greater than the radius R2 of the second roller 33. The central axis of the second roller 33 and the central axis of the first roller 32 are located in the same plane and do not intersect. The distance d between the central axis of the second roller 33 and the central axis of the first roller 32 is equal to the sum of the radii of the first roller 32 and the radii of the second roller 33.

[0031] This application uses a design where the radius of the first roller 32 is larger than the radius of the second roller 33, and the central axes of the two rollers satisfy a specific positional relationship. This design allows the second roller 33 to more effectively and evenly spread the glue on the first roller 32 when it squeezes the first roller 32, thereby improving the glue evenness and ensuring the quality of the glue obtained by the glue application device 4.

[0032] like Figure 7 As shown, the ratio of the radius R1 of the first roller 32 to the radius R2 of the second roller 33 is between 1.2 and 4. By limiting the ratio of the radius of the first roller 32 to the radius of the second roller 33 to between 1.2 and 4, this application can more precisely control the degree of compression and spreading of the adhesive on the first roller 32 by the second roller 33, so that the adhesive achieves the best uniformity, thereby ensuring the stability and consistency of the adhesive coating quality.

[0033] A spacing adjustment component (not shown in the figure) is provided between the base 31 and the second roller 33 to adjust the distance between the second roller 33 and the first roller 32. By providing this spacing adjustment component between the base 31 and the second roller 33, the distance between the second roller 33 and the first roller 32 can be flexibly adjusted according to different adhesive types, coating requirements, and workpiece characteristics. This changes the squeezing pressure of the second roller 33 on the adhesive on the first roller 32, achieving optimal adhesive evenness. Furthermore, by adjusting the spacing, the equipment can adapt to a wider variety of workpieces and coating processes, expanding its application range and improving its versatility and flexibility.

[0034] Specifically, the spacing adjustment assembly includes a fixed plate and a threaded rod. The fixed plate is mounted on the base 31, and the threaded rod passes through the fixed plate and is threadedly connected to the second roller 33.

[0035] like Figure 8 As shown, the gluing device 4 has a support plate 41, on which a gluing shaft 42 and a rotating motor 43 are provided. The gluing shaft 42 is configured to be driven by the rotating motor 43, so that the gluing shaft 42 rotates, thereby better absorbing the glue from the dipping device 3 or better coating the glue onto the workpiece 6 to be coated.

[0036] like Figure 6 As shown, it also includes a fine-tuning mechanism 5, which is connected to the processing platform 2 and used to adjust the position of the processing platform 2 on the frame 1. This application uses the fine-tuning mechanism 5 to move the processing platform 2 along the length, width, or height of the frame 1 via a direction adjustment component, and can also adjust the angle of the workpiece to be coated in multiple directions. This allows for minute position adjustments to the workpiece 6 mounted on the processing platform 2, further improving the workpiece's positioning accuracy and ensuring the accuracy of the adhesive application position.

[0037] Specifically, the fine-tuning mechanism 5 includes a fixed seat 51, a first adjusting seat 52, a second adjusting seat 53, a third adjusting seat 54, and a fourth adjusting seat 55 arranged in sequence, with the processing platform 2 disposed on the fourth adjusting seat 55.

[0038] Among them, the fixed seat 51, the first adjusting seat 52, the second adjusting seat 53, and the third adjusting seat 54 are all equipped with a push motor 56. The push motor 56 on the fixed seat 51 abuts against the first adjusting seat 52. The first adjusting seat 52 is configured to be driven by the push motor 56 on the fixed seat 51 to move relative to the fixed seat 51 along the left side of the frame 1. The second adjusting seat 53, the third adjusting seat 54, the fourth adjusting seat 55 and the processing platform 2, which are located above the first adjusting seat 52, move along the left side of the frame 1 along with the first adjusting seat 52.

[0039] The drive motor 56 of the first adjustment seat 52 abuts against the second adjustment seat 53, which is configured to be driven by the drive motor 56 of the first adjustment seat 52 to move relative to the first adjustment seat 52 along the right side of the frame 1; while the third adjustment seat 54, the fourth adjustment seat 55 and the processing platform 2, which are disposed above the second adjustment seat 53, move along the right side of the frame 1 with the second adjustment seat 53.

[0040] The drive motor 56 of the second adjustment seat 53 abuts against the third adjustment seat 54, which is configured to be driven by the drive motor 56 of the second adjustment seat 53 to move relative to the second adjustment seat 53 along the front side of the frame 1; while the fourth adjustment seat 55 and the processing platform 2, which are disposed above the third adjustment seat 54, move along the front side of the frame 1 with the third adjustment seat 54.

[0041] The drive motor 56 of the third adjustment seat 54 abuts against the fourth adjustment seat 55, which is configured to be driven by the drive motor 56 of the third adjustment seat 54 to move relative to the third adjustment seat 54 along the rear side of the frame 1; while the processing platform 2 disposed above the fourth adjustment seat 55 moves along the rear side of the frame 1 with the fourth adjustment seat 55.

[0042] The fourth adjustment seat 55 is equipped with a lifting motor, and the processing platform 2 is configured to be driven by the lifting motor on the fourth adjustment seat 55 to move along the height direction of the frame 1.

[0043] like Figure 1-8As shown, the frame 1 includes a base 11 and a moving platform 12. The dipping device 3, the processing platform 2, and the moving platform 12 are all mounted on the base 11, and the gluing device 4 is mounted on the moving platform 12 and moves relative to the base 11 via the moving platform 12. This application divides the frame 1 into a base 11 and a moving platform 12. The dipping device 3 and the processing platform 2 are mounted on the base 11, and the gluing device 4 is mounted on the moving platform 12. The movement of the moving platform 12 relative to the base 11 allows the gluing device 4 to more flexibly reach different positions for gluing operations, adapting to workpieces of different shapes and sizes, thus improving the flexibility and efficiency of gluing. Furthermore, this structural design makes the layout of the various components of the equipment more rational, facilitating the installation, debugging, and maintenance of the equipment, while also improving the stability and reliability of the equipment.

[0044] like Figure 1-8 As shown, the mobile platform 12 includes a support 121, a first moving device 122, and a second moving device 123. The support 121 extends along the height direction of the base 11. The first moving device 122 is mounted on the support 121 and configured to move along the height direction of the base 11. The second moving device 123 is mounted on the first moving device 122 and configured to move along the length or width direction of the base 11. The gluing device 4 is mounted on the second moving device 123 and cooperates with the first moving device 122 and the second moving device 123 to move along the height and length directions or along the height and width directions of the base 11, thereby achieving multi-axis linkage.

[0045] This application, through the cooperation of the first moving device 122 and the second moving device 123, enables the gluing device 4 to move along the height and length directions or the height and width directions of the substrate 11, achieving flexible movement of the gluing device 4 in three-dimensional space. This meets the gluing needs of workpieces with various complex shapes, improving the comprehensiveness and accuracy of gluing. The flexible movement in multiple directions allows the gluing device 4 to quickly and accurately reach the required gluing position, reducing pauses and adjustment time during the gluing process, improving gluing efficiency, and ensuring the uniformity and quality of the gluing.

[0046] Specifically, a first guide structure is provided between the first moving device 122 and the support 121 to allow the first moving device 122 to move along the extension direction of the support 121, thereby allowing the first moving device 122 to move along the height direction of the base 11. The first moving device 122 includes a first lead screw, a first nut, and a first stepper motor. The first lead screw is vertically mounted on the support 121 along the height direction of the base 11, and the first nut is sleeved on the first lead screw and connected to the first moving device 122. 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 122 to move.

[0047] Similarly, a second guide structure is provided between the second moving device 123 and the first moving device 122 to allow the second moving device 123 to move along the first moving device 122, thereby moving the second moving device 123 along the length or width direction of the base 11. The second moving device 123 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 122 (i.e., the length or width direction of the base 11), and the second nut is sleeved on the second lead screw and connected to the second moving device 123. 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 123 to move.
