Description

Technical Field

[0001] This invention relates to the field of adhesive coating technology for sheet materials, and more specifically to an adhesive coating device. Background Technology

[0002] In existing adhesive coating equipment, multiple adhesive coating mechanisms are typically set up to simultaneously coat materials with multiple adhesive surfaces. However, in existing devices, the adhesive coating mechanisms are often arranged in parallel or in the same direction, which occupies a large space. The switching paths between the adhesive coating mechanisms are also long. Furthermore, if the adhesive coating shaft on the first adhesive coating mechanism cannot be quickly switched to the adhesive coating shaft of the second adhesive coating mechanism after finishing coating, the residual adhesive on the board is easily exposed to the air for too long, resulting in the formation of a dry film on its surface. This not only affects the adhesion performance of the adhesive layer but may also cause poor bonding of subsequent products and reduce processing consistency.

[0003] Therefore, optimizing the layout of each glue-applying mechanism while ensuring the glue-applying function, and achieving a compact arrangement and efficient switching between the glue-applying mechanisms, has become one of the technical problems that urgently need to be solved in this field. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides an adhesive application device in which the first adhesive application shaft and the second adhesive application shaft are close to each other, achieving a compact layout in space.

The first adjusting shaft is provided with a first protrusion. When the first driving member is activated, it can drive the first adjusting shaft to rotate so that the first protrusion moves closer to or further away from the first adhesive shaft, thereby changing the adhesive coating thickness on the first adhesive shaft. The second base is also provided with a second adjusting shaft and a second driving member connected to the second adjusting shaft. The second adjusting shaft is provided with a second protrusion. When the second driving member is activated, it can drive the second adjusting shaft to rotate so that the second protrusion is close to or away from the first adhesive shaft, thereby changing the adhesive coating thickness on the second adhesive shaft.

[0020] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] like Figure 1-11The adhesive applicator shown includes a frame 1, a first adhesive applicator 2 and a second adhesive applicator 3, with the first adhesive applicator 2 and the second adhesive applicator 3 respectively mounted on the frame 1.

[0024] The first adhesive application mechanism 2 includes a first base 21 and a first adhesive application shaft 22 disposed on one side of the first base 21. The first adhesive application shaft 22 is used to apply adhesive to the vertical surface of the workpiece. The second adhesive application mechanism 3 includes a second base 31 and a second adhesive application shaft 32 disposed thereon, used to apply adhesive to the inclined surface of the workpiece. The first adhesive application mechanism 2 is arranged laterally, so that the first adhesive application shaft 22 is in a vertical state; the second adhesive application mechanism 3 is arranged vertically at an inclined angle, so that the second adhesive application shaft 32 is in an inclined state, thereby adapting to the adhesive application requirements of different surfaces of the workpiece.

[0025] Through the above structural design, the first glue-applying shaft 22 and the second glue-applying shaft 32 are spatially close to each other, achieving a more compact mechanism arrangement without increasing the overall space occupied by the equipment. This effectively shortens the switching path of the workpiece between the two glue-applying mechanisms, reduces the time the glue is exposed to air, avoids the problem of dry film forming on the glue surface due to air oxidation, improves the adhesion and bonding stability of the glue layer, and thus improves the consistency of glue-applying quality.

[0026] During use, when the edge of a workpiece contains both vertical and inclined surfaces, simultaneous glue application can be performed using a first glue application mechanism 2 arranged horizontally and a second glue application mechanism 3 arranged vertically at an inclined angle. The first glue application mechanism 2 has a vertically arranged first glue application shaft 22 for precisely applying glue to the vertical edge of the workpiece; the second glue application mechanism 3 has a second glue application shaft 32 arranged at a certain angle for attaching and applying the edge sealing tape located on the inclined surface.

[0027] Because the first adhesive application mechanism 2 and the second adhesive application mechanism 3 are arranged in a staggered manner in space, and their corresponding first adhesive application shaft 22 and second adhesive application shaft 32 are close to each other, the transmission distance of the workpiece between the two adhesive application mechanisms is significantly shortened, effectively reducing the time that the adhesive is exposed to air during the process from application to bonding. This structure not only avoids the problem of dry film forming on the adhesive surface due to air oxidation, but also ensures the freshness and adhesion performance of the adhesive layer, improving the stability and overall quality of subsequent edge sealing processes.

[0028] In this embodiment, the second base 31 and the second adhesive application shaft 32 are inclined relative to the horizontal plane. The inclination angle can be any angle greater than 0 degrees and less than 90 degrees, such as 30 degrees, 45 degrees, or 60 degrees, preferably 45 degrees, to balance the adhesive coverage area and the rationality of the structural arrangement. Although this embodiment does not primarily set the angle at 0 degrees or 90 degrees, this mechanism is also applicable to scenarios with 0 degrees (horizontal arrangement) or 90 degrees (vertical arrangement). It can be flexibly adjusted according to actual application needs, making it highly adaptable and unrestricted in use.

[0029] Based on the above structural design, the inclined second gluing mechanism 3 and the horizontally arranged first gluing mechanism 2 can work together to enable the device to simultaneously perform multi-angle gluing on irregularly shaped workpieces with both inclined and vertical surfaces, effectively improving processing efficiency and reducing the time cost of multiple clamping operations. Furthermore, the two gluing mechanisms can also work independently, respectively for gluing workpieces with a single vertical or inclined surface, further enhancing the system's adaptability and flexibility. This structure not only improves the feasibility of gluing irregularly shaped workpieces but also enhances the overall equipment's operational capability and stability under complex working conditions.

[0030] In this embodiment, the first base 21 can be selected as either a one-piece molded structure or a combined structure composed of multiple base pieces, depending on the specific application requirements. When using a multi-base piece assembly, the first glue inlet channel 211 consists of multiple interconnected channels, each channel segment being arranged inside each base piece, forming a complete and continuous glue inlet path after assembly. This ensures that the glue can be uniformly and stably delivered to the coating area, exhibiting good modular adaptability and ease of maintenance. Similarly, the second base 31 can also be a one-piece structure or composed of multiple base pieces. When using an assembly structure, the second glue inlet channel 311 also consists of multiple interconnected channels, each channel segment being arranged on a corresponding base piece. By assembling, a smooth glue supply channel is formed, ensuring the continuity and reliability of the coating process.

[0031] Furthermore, to accommodate the varying amounts of adhesive required at different locations on the workpiece, the surface of the first adhesive application shaft 22 is provided with a smooth surface area and a concave surface area, each comprising at least one segment. During rotation, the smooth surface area and the concave surface area adhere to different amounts of adhesive, allowing the first adhesive application shaft 22 to provide different adhesive distributions according to different parts of the workpiece during operation. This achieves a more precise and efficient adhesive application effect, avoiding over- or under-adhesion and improving overall processing quality. The surface structure of the second adhesive application shaft 32 is similar to that of the first adhesive application shaft 22, also featuring a smooth surface area and a concave surface area, also comprising at least one segment. This design not only enhances the device's adaptability to adhesive application on complex surfaces but also strengthens the process control capabilities for diverse workpiece structures, exhibiting excellent processing consistency and flexibility.

[0032] participate Figure 5 , Figure 9 A first glue inlet channel 211 is provided within the first base 21. The first glue inlet channel 211 includes a first channel inlet 2111 and a first channel outlet 2112 communicating with it. The first channel inlet 2111 is located at the top of the first base 21 and is connected to a first glue inlet valve 24. The first channel outlet 2112 faces the first glue application shaft 22 and is used to accurately introduce glue into the first glue application shaft 22, thereby achieving quantitative glue supply to the surface glue layer and effectively ensuring glue coating uniformity and process stability.

[0033] Similarly, the second base 31 is also provided with a second glue inlet channel 311, a second inlet channel 3111 connected to it, and a second outlet channel 3112. The second inlet channel 3111 is connected to the second glue inlet valve 34 at the top of the second base 31, and the second outlet channel 3112 faces the second glue application shaft 32, thereby achieving stable glue supply to the second glue application shaft 32, meeting the glue application needs of different processing positions, and further improving the multi-station adaptability of the equipment.

[0034] Preferably, the first glue inlet valve 24 is a switching valve used to control whether glue enters the first glue inlet channel 211. Specifically, the switching valve adopts a cylinder structure, and the telescopic rod of the cylinder is inserted into the first glue inlet channel 211 to play an adjustment role. When the telescopic rod is fully extended and inserted into the first glue inlet channel 211, it can block the glue passage, thereby closing the first glue inlet channel 211 at that position; when the telescopic rod is fully retracted and away from the first glue inlet channel 211, the first glue inlet channel 211 is in the maximum open state, realizing the maximum glue supply. By adjusting the depth of the cylinder telescopic rod inserted into the first glue inlet channel 211, the opening of the channel can be precisely controlled, thereby realizing continuous and adjustable glue supply, effectively improving the response speed and quantitative control accuracy of the glue application process.

[0035] Similarly, the second glue inlet valve 34 also adopts the same structure and working principle. By adjusting the extension and retraction state of its internal cylinder, the opening of the second glue inlet channel 311 is controlled in real time to adjust the glue supply amount of the second glue application shaft 32. The above structure not only improves the automation level of the glue supply system, but also enhances the adaptability and processing consistency of the equipment in response to different glue application requirements.

[0036] In other embodiments, the first glue inlet valve 24 and / or the second glue inlet valve 34 can also be selected as motor-driven structures. Specifically, an electric actuator (such as a stepper motor or servo motor) equipped with angle control function can be used to drive the rotary valve core or slide valve to achieve the opening and closing control of the first glue inlet channel 211 and the second glue inlet channel 311. The rotation angle of the motor can be precisely set by the control system, thereby indirectly adjusting the opening degree of the first glue inlet channel 211 and the second glue inlet channel 311, achieving high-precision adjustment of the glue feed rate. Compared with the cylinder structure, the motor-driven method has a faster response speed, higher control accuracy, and is easier to link with the glue application program for control, making it suitable for automated glue application production lines with high requirements for glue supply consistency, repeatability, and process flexibility. By designing the glue inlet valve as an optional motor or cylinder-driven structure, not only is the versatility and adaptability of the system enhanced, but the design also provides convenience for flexibly selecting the drive method according to the production environment, improving the modularity and maintenance convenience of the whole machine.

[0037] Specifically, to enhance the installation flexibility and adaptability of the adhesive application mechanism, a first slide 4 extending laterally is provided on one side of the frame 1. The first adhesive application mechanism 2 is mounted on this first slide 4 and can move laterally along its trajectory to precisely align with the vertical surface of the workpiece and complete the adhesive application operation on the corresponding edge. On the other side of the frame 1, a second slide 5 arranged at a preset tilt angle is provided. The second adhesive application mechanism 3 can move along the second slide 5 in the tilt direction to smoothly conform to the tilted surface of the workpiece, achieving efficient and continuous adhesive application. These features significantly enhance the equipment's adaptability to multi-angle and multi-boundary structures, expanding its application range.

[0038] Furthermore, both the first slide 4 and the second slide 5 are equipped with sliders and guide rails that cooperate with the sliders. Stepper motors or servo motors can be respectively equipped on the first slide 4 and the second slide 5 as drive sources, and the first glue-applying mechanism 2 and the second glue-applying mechanism 3 are driven by a screw drive mechanism to achieve precise movement. Specifically, the drive motor is connected to a ball screw through a coupling. The rotation of the motor drives the screw to rotate, thereby driving the glue-applying mechanism mounted on the slider to move smoothly along the guide rail, achieving high-precision positioning operations at different positions and angles. The screw drive structure not only has high transmission efficiency and strong positioning accuracy, but also has good load-bearing capacity, ensuring the operational stability and repeatability of the glue-applying process.

[0039] More importantly, by setting up a central controller, all drive motors can be electrically connected to the central controller. The controller presets motion commands based on the size and edge structure of the workpiece, and automatically controls the start, stop, speed and movement distance of each motor, forming a programmable and automated glue coating control system. This makes the entire glue coating process responsive and precise in positioning, which not only improves the automation level of the equipment, but also effectively reduces manual intervention, and improves production efficiency and glue coating consistency.

[0040] See Figure 1 To avoid interference during the adhesive application process, a clearance zone 314 is provided at the top of the second base 31. This clearance zone 314 is constructed by cutting or chamfering the protruding angle formed by the inclined arrangement of the second base 31, ensuring that it is close enough to avoid the workpiece or workpiece conveying device, thus preventing equipment collisions or operational restrictions caused by structural interference. This design not only ensures the normal operation of the equipment in a compact arrangement but also improves the overall structural adaptability and safety of the device, contributing to the continuity and stability of the adhesive application operation.

[0041] Furthermore, the first glue application mechanism 2 also includes a first glue quantity sensor 27 disposed on the other side of the first base 21, and the second glue application mechanism 3 also includes a second glue quantity sensor 37 disposed on the other side of the second base 31. The glue quantity sensor preferably employs a non-contact sensor based on the principle of laser diffuse reflection (such as a BGX40NGW laser detector) for real-time monitoring of the glue application status. Specifically, the sensor can determine whether the glue is being output normally by emitting a laser beam and receiving the light signal reflected from the glue surface. When the glue quantity is insufficient, glue is interrupted, or glue accumulation is abnormal, the intensity of the reflected light and the feedback signal will change, and the system will issue a prompt or adjust the glue application parameters accordingly. This structural design not only achieves high-precision detection of the glue output status but also improves the closed-loop control capability of the glue application process, enabling the detection of glue abnormalities at an early stage, preventing defective products from flowing into subsequent processes, thereby effectively ensuring the consistency of glue application and the stability of finished product quality.

[0042] To facilitate workpiece positioning, a first backing plate 23 is provided on one side of the first base 21 for contacting the vertical surface of the workpiece, and a second backing plate 33 is provided on one side of the second base 31. The first backing plate 23 includes an abutment plate 332 for contacting the inclined surface of the workpiece, and a fixing plate 331 that is perpendicular to the abutment plate 332 and connected to the second base 31, which helps to stably support and position the workpiece during the glue application process.

[0043] See Figure 6-7 , Figure 10-11To achieve flexible adjustment of the adhesive coating thickness, the first base 21 is also provided with a first adjusting shaft 28 and a first driving member 25 connected to the first adjusting shaft 28. The first adjusting shaft 28 is provided with a first protrusion. When the first driving member 25 is activated, it can drive the first adjusting shaft 28 to rotate, so that the first protrusion moves closer to or away from the first adhesive coating shaft 22, thereby changing the adhesive coating thickness on the first adhesive coating shaft 22. Similarly, the second base 31 is provided with a second adjusting shaft 38 and a second driving member 35 connected to the second adjusting shaft 38. The second adjusting shaft 38 is provided with a second protrusion. When the second driving member 35 is activated, it can drive the second adjusting shaft 38 to rotate, so that the second protrusion moves closer to or away from the second adhesive coating shaft 32, thereby changing the adhesive coating thickness on the second adhesive coating shaft 32, thus enhancing the adjustment capability of the device under different process requirements.

[0044] The first adjusting shaft 28 and the first base 21 are rotatably connected via bearings. This allows the first base 21 to provide stable support for the first adjusting shaft 28 without affecting the independent rotation of the first adhesive application shaft 22. This ensures smooth operation and sensitive response of the first adhesive application shaft 22, improving adhesive application accuracy and device reliability. The top end of the first adjusting shaft 28 is connected to the drive end of the first driving component 25 via a first connecting rod 26, facilitating efficient transmission of driving force to the first adjusting shaft 28 and enabling dynamic rotation of the first adjusting shaft 28.

[0045] Similarly, the second adjusting shaft 38 is also rotatably connected to the second base 31 via a bearing, enabling the second base 31 to stably support the second adjusting shaft 38 while ensuring the normal rotation of the second adhesive application shaft 32 without interference, further improving the synchronization and stability of the equipment in dual-station adhesive application operations. The top end of the second adjusting shaft 38 is connected to the drive end of the second drive component 35 via a second connecting rod 36, ensuring the accuracy and response speed of its adjustment action.

[0046] Furthermore, the first base 21 has an opening structure, at which both the first adhesive application shaft 22 and the first adjustment shaft 28 are located. This structure provides necessary support for the first adjustment shaft 28 and avoids interference between the first base 21 and the first adjustment shaft 28, improving the overall assembly's compactness and structural compatibility. Similarly, the second base 31 also has a corresponding opening, where both the second adhesive application shaft 32 and the second adjustment shaft 38 are arranged. This rational spatial design ensures non-interference and independent operation during assembly, thereby optimizing the overall structural layout and effectively improving the operating efficiency and space utilization of the dual-axis adhesive application system.

[0047] In this embodiment, the first driving component 25 is exemplified by a cylinder. The tail end of the cylinder is rotatably connected to the first base 21 via a hinge, and the cylinder's telescopic rod is also rotatably connected to one end of the first connecting rod 26 via a hinge. The other end of the first connecting rod 26 is fixedly connected to the top end of the first adjusting shaft 28. With this connection structure, the cylinder body can rotate appropriately during the driving process, thereby maintaining stability and guidance during extension and retraction. When the cylinder's telescopic rod extends outward, the first adjusting shaft 28 is driven to rotate in the forward direction via the connection of the first connecting rod 26; conversely, when the telescopic rod retracts, the first adjusting shaft 28 is driven to rotate in the reverse direction via the connection of the first connecting rod 26. By setting the stroke range of the cylinder's telescopic rod, the rotation angle of the first adjusting shaft 28 can be precisely limited, thereby improving the flexibility and positioning accuracy of the equipment adjustment.

[0048] Similarly, the second drive component 35 and the second adjustment shaft 38 also adopt the same structural design and drive principle. The second adjustment shaft 38 is rotated bidirectionally by a cylinder to ensure the synchronization and controllability of the dual-channel glue application system.

[0049] In other embodiments, the first driving element 25 may also be a motor, preferably an angle-controlled motor capable of forward and reverse rotation. In this case, the motor's output shaft is directly connected to the top end of the first adjusting shaft 28, and the first adjusting shaft 28 is driven to rotate in the corresponding direction by the forward or reverse rotation of the motor. The forward and reverse rotation angles of the motor can be limited by program control, thereby precisely setting the rotation range of the first adjusting shaft 28, which not only improves the adjustment response speed but also further enhances the degree of automation and repeatability accuracy.

[0050] Similarly, the second drive unit 35 can also be driven by a motor, and cooperate with the second adjustment shaft 38 to achieve the same functional effect and control method, which is suitable for multi-station glue application scenarios with high requirements for structural compactness and response accuracy.

[0051] Based on the above structural design, during the forward rotation of the first adjusting shaft 28, the first protrusion on it gradually moves away from the first adhesive application shaft 22, thereby gradually increasing the gap between them. This results in a gradual increase in the thickness of the adhesive layer formed on the surface of the first adhesive application shaft 22, meeting the requirement for a larger amount of adhesive. Conversely, when the first adjusting shaft 28 rotates in the reverse direction, the first protrusion gradually moves closer to the first adhesive application shaft 22, causing the gap to gradually decrease, and the thickness of the adhesive applied to its surface to decrease accordingly. When the first protrusion finally abuts against the first adhesive application shaft 22, the gap tends to be minimal, and the amount of adhesive applied is at its lowest. This structure allows for precise control of the adhesive thickness on the surface of the first adhesive application shaft 22, ensuring flexible adaptation to different adhesive thickness requirements during the adhesive application process on vertical workpieces, improving the uniformity of adhesive application and processing consistency.

[0052] Similarly, during forward rotation of the second adjusting shaft 38, the second protrusion on it gradually moves away from the second adhesive application shaft 32, increasing the gap between them and thus increasing the thickness of the adhesive layer. Conversely, when the second adjusting shaft 38 rotates in the reverse direction, the second protrusion gradually moves closer to the second adhesive application shaft 32, reducing the gap and decreasing the adhesive thickness. Finally, when the second protrusion fully contacts the second adhesive application shaft 32, the adhesive application amount reaches its minimum. This adjustment mechanism enables the second adhesive application shaft 32 to have excellent controllability of the adhesive layer thickness, adapting to the individualized needs of workpieces at different angles, especially inclined surfaces, during the adhesive application process. This effectively improves the equipment's adaptability under complex working conditions and the stability of processing quality.

[0053] Through the above-mentioned forward and reverse adjustment process, the device can achieve precise control of adhesive application on different workpieces and at different positions, avoiding poor bonding, glue waste or appearance defects caused by excessively thick or thin adhesive layers, thereby improving overall processing efficiency and finished product quality.

[0054] The first outlet 2112 of the first glue inlet channel 211 is located outside the rotation range of the first adjusting shaft 28, meaning that the rotation of the first adjusting shaft 28 during adjustment will not affect the size or shape of the first outlet 2112. Similarly, the second outlet 3112 of the second glue inlet channel 311 is also located outside the rotation range of the second adjusting shaft 38, ensuring that the rotation of the second adjusting shaft 38 does not affect the opening state of the second outlet 3112. This arrangement effectively avoids interference from the adjustment action on the glue outlet flow rate, resulting in higher glue dispensing stability and ensuring uniform and reliable glue output in each glue application operation, thereby improving the consistency of glue application quality and the stability of the finished product bonding effect.

[0055] See Figure 7 , Figure 11 To prevent glue dripping and contaminating the equipment or workpiece surface, the first base 21 is provided with a first receiving groove 212 located at the bottom of the first coating shaft 22. The first receiving groove 212 is connected to the first guide plate 29 through a first guide port 213 to guide excess glue on the first coating shaft 22 to drain. The second base 31 is also provided with a second receiving groove 312, a second guide port 313, and a second guide plate (not shown in the figure) corresponding to the second coating shaft 32, so as to effectively recover excess glue on the second coating shaft 32 and keep the working environment clean.

[0056] In terms of power transmission, the device also includes a drive motor 6. The first adhesive application shaft 22 is connected to the drive motor 6 via a first universal joint drive shaft 7, and the second adhesive application shaft 32 is connected to the same drive motor 6 via a second universal joint drive shaft 8, thereby simplifying the drive structure and reducing the complexity and cost of the drive system. The bottom of the first adhesive application shaft 22 is provided with a first connecting shaft 221, and the bottom of the second adhesive application shaft 32 is provided with a second connecting shaft 321, which are respectively connected to one end of the first universal joint drive shaft 7 and one end of the second universal joint drive shaft 8.

[0057] To achieve synchronous transmission, the frame 1 is equipped with a first transmission gear 71 connected to the other end of the first universal joint drive shaft 7, a second transmission gear 81 connected to the other end of the second universal joint drive shaft 8, and a third transmission gear 61 mounted on the drive shaft of the drive motor 6. These three gears are connected by a chain 9. Specifically, the frame 1 is also equipped with a tensioning wheel 91 to ensure a secure connection between the first transmission gear 71, the second transmission gear 81, and the third transmission gear 61 via the chain 9. This transmission structure ensures both the synchronicity of the two adhesive application shafts and provides good transmission efficiency and reliability.

[0058] In this embodiment, at least one heating tube (not shown in the figure) is provided on the first base 21 to indirectly heat the adhesive in the first adhesive inlet channel 211 in the adjacent area. This avoids the adhesive viscosity from increasing or the fluidity from decreasing due to low ambient temperature, thereby ensuring that the adhesive is always in a suitable working state during the coating process and improving the uniformity and stability of the coating. And / or, at least one heating tube may also be provided on the body of the first adhesive shaft 22. By heating the first adhesive shaft 22, the adhesive in contact with it maintains good fluidity, effectively reducing adhesive breakage, stringing, or solidification during the coating process, and further ensuring the continuity and adhesion quality of the adhesive layer.

[0059] Similarly, at least one heating tube may be provided on the second base 31 to indirectly heat the glue in the second glue inlet channel 311 in the adjacent area to achieve temperature regulation and control; and / or, a heating tube may be provided on the second glue application shaft 32 to maintain the coatability and adhesion of the glue by heating the second glue application shaft 32, which is particularly suitable for continuous glue application operations on workpieces of different materials or structural surfaces.

[0060] The above-mentioned heating structure configuration can effectively adjust the glue temperature under different working conditions, making the glue application process more environmentally adaptable and process stable. This not only improves the glue application quality but also helps to extend the service life of the glue and reduce the processing defect rate.

[0061] In this embodiment, the heating tube is preferably an electric heating tube with an internal electric heating wire. By electrically driving the heating wire, continuous heating of the surrounding structure can be achieved, thereby indirectly maintaining a constant temperature for the adhesive. This structure offers advantages such as fast heating response and high temperature control accuracy, helping to maintain the adhesive within a suitable viscosity range, ensuring fluidity and stability during the application process, and further improving the uniformity of application, adhesion, and processing reliability. Simultaneously, the electric heating tube has a simple structure and is easy to integrate, facilitating a compact design and easier maintenance of the overall device.

[0062] See also Figure 1-3 In this embodiment, the device further includes an edge banding grooving mechanism 11 for grooving the edge banding. Specifically, when the device performs edge banding on a workpiece, if the edge of the workpiece includes both vertical and inclined surfaces, the edge banding needs to be pre-grooved to allow it to fold smoothly during subsequent rolling and simultaneously adhere to the workpiece edges of both the vertical and inclined surfaces, improving the integrity and aesthetics of the edge banding.

[0063] To achieve stable conveying and precise cutting of the edge banding tape, the frame 1 is equipped with guide wheels 111 for guiding the tape's forward path and a cutting blade 121 for cutting the tape. The cutting blade 121 is driven to move by a third drive unit 12, thereby achieving fixed-length cutting of the edge banding tape. Furthermore, the frame 1 is also equipped with a fixed base 13, which has a through hole through which the edge banding tape can pass. When the third drive unit 12 drives the cutting blade 121 to move along the set path and engage with the through hole of the fixed base 13, the cutting operation of the edge banding tape can be completed efficiently, ensuring that the length of the edge banding tape matches the edge of the workpiece, thereby improving edge banding efficiency and finished product accuracy.

[0064] Furthermore, to further enhance the bonding strength and adaptability between the edge banding tape and the workpiece edge, the device also includes a mounting base 15 mounted on the frame 1. The mounting base 15 is equipped with at least one rolling roller 14 for rolling the edge banding tape. Preferably, the rolling roller 14 is arranged at an angle to accommodate the edge banding processing needs of inclined surfaces on irregularly shaped workpieces. To enhance the versatility of the edge banding structure, multiple rolling rollers 14 can be provided according to actual processing requirements. For example, rolling rollers 14 suitable for both inclined and vertical surfaces can be simultaneously provided on the mounting base 15 to effectively roll the workpiece edges at different angles, further improving the uniformity and firmness of the edge banding.

[0065] The mounting base 15 is connected to the frame 1 via the fourth drive component 151, enabling vertical adjustment to accommodate workpieces of different thicknesses or edge-sealing heights, thereby enhancing the equipment's adaptability in multi-specification edge-sealing operations. The rolling roller 14 is connected to the rotary motor 16 on the frame 1 via the third universal drive shaft 17. The drive shaft of the rotary motor 16 is equipped with a fourth transmission gear 161, and the third universal drive shaft 17 is equipped with a fifth transmission gear 171. Synchronous transmission is achieved between the two via a drive chain 162. This transmission structure not only ensures the stable rotation of the rolling roller 14 but also continuously outputs uniform rolling pressure at complex angles, allowing the edge-sealing tape to be firmly pressed onto the workpiece edge after pre-cutting and positioning, thus effectively improving the overall quality and processing reliability of the edge-sealing.

[0066] To achieve automatic matching of the edge banding tape and the workpiece length, the device may further include a workpiece length detection unit. This detection unit acquires workpiece length information in real time through a laser rangefinder sensor. The control system precisely controls the feed length of the edge banding tape based on the detection results, and when the set value is reached, the third drive component 12 drives the tape cutter 121 to cut the edge banding tape, thereby ensuring that the edge banding tape and the workpiece edge length are consistent, improving edge banding efficiency and avoiding material waste.

[0067] In summary, the adhesive applicator of the present invention achieves a compact integration by arranging the first adhesive applicator 2 laterally and the second adhesive applicator 3 at an inclined angle, making the first adhesive applicator shaft 22 vertical and the second adhesive applicator shaft 32 at an inclined angle. This arrangement significantly shortens the movement path of the workpiece between the two adhesive applicators, improves the efficiency and continuity of workpiece switching, reduces the risk of adhesive evaporation and dry film formation during exposure, further ensures the adhesion stability and bonding reliability of the adhesive layer, and effectively improves the adhesive application efficiency and product processing cycle time.

[0068] The adhesive application device of this invention features a first adhesive application shaft 22 arranged vertically, suitable for efficient adhesive application to the vertical surfaces of workpieces; and a second adhesive application shaft 32 arranged at a preset angle, capable of precisely matching the adhesive application requirements of inclined or angled surfaces of workpieces. Through this axial combination arrangement, the device can achieve simultaneous adhesive application to surfaces in multiple directions, making it particularly suitable for processing workpieces with complex structures and irregular edges. This broadens the device's applicability, enhances its compatibility with various workpiece shapes, and improves the adaptability and operational flexibility of the equipment in customized and irregularly shaped adhesive application tasks.

[0069] This invention relates to a glue-applying device. The spatial arrangement of two glue-applying mechanisms, coupled with a sliding block, drive motor, and lead screw transmission structure, enables high-precision control of the movement path of the glue-applying mechanisms. This ensures that the workpiece completes multi-sided glue application under consistent rhythm and trajectory, thereby significantly improving the bonding consistency and appearance quality of the product. Simultaneously, this structure possesses good scalability and a foundation for automation upgrades, facilitating the promotion and application of the equipment in intelligent manufacturing and continuous production lines, demonstrating excellent practical value and engineering application prospects.
