[0019] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0021] The glue gun 100 of the present invention is described below with reference to the accompanying drawings.

[0022] According to an embodiment of the present invention, the glue gun 100, such as Figure 1As shown, the glue applicator 100 includes: a glue applicator body 1 and a visual component 2. The glue applicator body 1 includes a glue applicator head 11. The visual component 2 is mounted on the glue applicator body 1 and includes a camera 21 and a display screen 22. The camera 21 is positioned close to the glue applicator head 11 and facing the glue outlet 111 of the glue applicator head 11. The camera 21 and the display screen 22 are connected by a signal. The display screen 22 is used to receive and display the video information collected by the camera 21 in real time.

[0023] In automobile manufacturing, applying sealant to welds is a key process for preventing leaks and corrosion. Manual application requires workers to hold a glue gun, watch the weld seam with their eyes, control the nozzle to move along the weld seam at a constant speed, and squeeze out glue strips to seal the weld.

[0024] In related technologies, there are situations where manual application of adhesive to the vehicle body structure makes it impossible to visually inspect the weld seams. For example, if the rear door of a car uses a flip-down door that opens by tilting it, the weld seam between the rear door and the rear floor cannot be visually inspected during manual adhesive application. Whether the adhesive is applied inside the passenger compartment by workers or after removing the door, the production process becomes cumbersome, inefficient, and has room for improvement.

[0025] Therefore, the present invention provides a glue applicator 100, wherein the glue applicator body 1 has a glue applicator head 11, and the glue outlet 111 of the glue applicator head 11 is used to extrude glue strips. The glue applicator 100 is also provided with a viewing component 2, which is mounted on the glue applicator body 1. The viewing component 2 includes a camera 21 and a display screen 22. The camera 21 is mounted near the glue applicator head 11 and is positioned facing the glue outlet 111 of the glue applicator head 11.

[0026] The display screen 22 is connected to the camera 21 via a signal transmission line or wirelessly via a Wi-Fi module. The display screen 22 is used to receive and display the video information captured by the camera 21 in real time, thereby displaying the video image intuitively.

[0027] The camera 21 can capture image information near the glue outlet 111 of the glue application gun head 11 in real time. When applying glue, the operator holds the glue application gun body 1 and points the glue application gun head 11 toward the weld. The camera 21, which is set on the glue application gun body 1, is positioned toward the glue outlet 111 of the glue application gun head 11. During the glue application process, the camera 21 naturally faces the weld, thus enabling the camera 21 to capture and transmit information about the area around the weld in real time, presenting a detailed image of the weld area to be glued on the display screen 22.

[0028] In this way, when operators need to apply adhesive to weld seams that are not visually visible, they can directly extend the adhesive gun body 1 to the weld area. The camera 21 can then capture and transmit video information of the area around the weld, presenting a detailed view of the weld area on the display screen 22. Operators can then perform the adhesive application based on the video information displayed on the screen 22. Using this real-time video information, operators can accurately determine whether the adhesive gun head 11 is correctly positioned on the weld seam where manual application is not possible. Using the visual component 2 eliminates the need to remove structures obstructing the view, and users do not need to painstakingly find a location where the weld can be seen, thus reducing the difficulty of the adhesive application operation, streamlining the production process, and improving overall efficiency.

[0029] Furthermore, during the adhesive application process, operators can also check the quality of the adhesive applied to the weld seam through the video information displayed on screen 22, confirming whether the adhesive evenly covers the weld area, thereby improving the accuracy and efficiency of the adhesive application work. Additionally, after the adhesive application process is completed, operators can also use the video information displayed on screen 22 to meticulously confirm and inspect the quality of the adhesive application. In this way, various defects that may occur during the adhesive application process can be detected and corrected in a timely manner, effectively reducing the failure rate caused by adhesive quality problems and improving overall production efficiency and product quality.

[0030] According to an embodiment of the present invention, the glue application gun 100, by providing a visual component 2, allows operators to directly extend the glue application gun body 1 to the weld area when they need to apply glue to weld seams that are not visually visible. The camera 21 can then capture and transmit video information of the area surrounding the weld seam, presenting a detailed view of the weld area on the display screen 22. Operators can directly apply glue based on the video information displayed on the display screen 22 without removing structures obstructing the view, and users do not need to painstakingly locate a position where the weld seam can be seen. This reduces the difficulty of the glue application operation, streamlines the production process, and improves overall efficiency.

[0031] In some embodiments of the present invention, the distance between the camera 21 and the glue outlet 111 of the glue gun head 11 is 10-50mm.

[0032] When the camera 21 is too close to the glue outlet 111 of the glue application gun head 11, the field of view of the camera 21 is too narrow, making it easy to miss the observation target. During the glue application process, the weld seam is easily missed after the glue application gun head 11 moves, resulting in poor operation continuity and reduced operation efficiency. When the camera 21 is too far from the glue outlet 111 of the glue application gun head 11, it is not easy to observe the weld seam, which also leads to reduced operation efficiency.

[0033] Therefore, the present invention preferably designs the distance between the camera 21 and the glue outlet 111 of the glue gun head 11 to be 10-50mm, which achieves a balance between close-range fine observation and wide-angle field of view, making the observation of the weld seam clearer and improving the efficiency of glue application.

[0034] Optionally, the distance between the camera 21 and the glue outlet 111 of the glue gun head 11 can be 12mm, 15mm, 20mm, 25mm or 30mm, etc.

[0035] In some embodiments of the present invention, a replaceable transparent protective sheet or cover is provided at the front end of the lens of the camera 21, and the protective sheet is snapped or screwed onto the camera housing. During continuous glue application, if glue mist or splatter contaminates the protective sheet and causes the image to become blurry, the operator can quickly replace the protective sheet by hand without disassembling the entire camera or interrupting the operation for too long, ensuring the continuous effectiveness of the visual components and reducing the difficulty of maintenance operations.

[0036] In other embodiments of the present invention, a ring-shaped air-blowing cleaning device is provided around the lens of the camera 21. The air-blowing cleaning device is connected to the compressed air pipeline of the glue gun 100 through a miniature air guide tube. When the operator observes that the image on the display screen 22 becomes blurry due to glue mist, dust, etc., the operator can press the air valve button located near the handle 12 to allow compressed air to be sprayed out from the ring-shaped air-blowing cleaning device through the miniature air guide tube to clean the lens surface of the camera 21.

[0037] In this way, during continuous glue application, when glue mist or splatter contaminates the protective film and causes the image to become blurry, the clear image can be quickly restored without the operator stopping the machine or manually wiping the lens, ensuring the reliability of monitoring and the continuity of operation during continuous glue application.

[0038] In some embodiments of the present invention, the camera 21 is fixedly connected to the glue gun body 1.

[0039] In this way, the distance between the camera 21 and the glue outlet 111 of the glue gun head 11 is relatively fixed, and the glue gun 100 can be used directly without adjusting the position of the camera 21 each time it is used, which is convenient.

[0040] In some specific embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the camera 21 and the display screen 22 are connected by a signal transmission line. The visual component 2 also includes a protective shell 23. The signal transmission line passes through the channel inside the protective shell 23 to connect the camera 21 and the display screen 22. The camera 21 is fixedly connected to the end of the protective shell 23, thereby fixing the camera 21, improving the stability of the camera 21's arrangement, and helping to improve the stability of the captured image.

[0041] The glue application gun body 1 includes a glue application gun barrel 13 and a glue delivery tube 14. The glue delivery tube 14 is connected to the glue application gun head 11 and is used to deliver glue to the glue application gun head 11. The glue application gun barrel 13 is covered by the glue delivery tube 14. The glue application gun barrel 13 has high structural strength, which can protect the glue delivery tube 14 and improve the working reliability of the glue application gun body 1.

[0042] The protective shell 23 is inserted through the glue gun barrel 13. The glue gun barrel 13 can protect the protective shell 23 and can stably limit the protective shell inside. The glue gun barrel 13 is fixedly connected to the protective shell 23, thereby fixing the camera 21 on the protective shell 23 to the glue gun body 1, improving the reliability of the glue gun 100.

[0043] In some other embodiments of the present invention, the camera 21 is slidably disposed relative to the glue gun body 1.

[0044] The camera 21 is set to slide relative to the glue gun body 1, that is, the camera 21 can slide relative to the glue outlet 111 of the glue gun head 11. The distance between the camera 21 and the glue outlet 111 can be dynamically adjusted according to actual needs to improve the observation clarity of the camera 21.

[0045] In some specific embodiments of the present invention, the camera 21 is fitted onto the glue gun body 1 via retaining rings, and the spacing between the retaining rings is adjusted by screws. Tightening the screws securely connects the retaining rings to the glue gun body 1, thereby stabilizing the shooting and improving the working reliability of the glue gun 100; while loosening the screws drives the retaining rings to move relative to the glue gun body 1, thereby changing the installation position of the camera 21 and altering the position of the camera 21 relative to the glue outlet 111 of the glue gun head 11.

[0046] In some embodiments of the present invention, such as Figure 3 As shown, the glue gun body 1 includes a handle 12 and a glue gun barrel 13. The glue gun head 11 is installed at the end of the glue gun barrel 13. The handle 12 is connected to the other end of the glue gun barrel 13 away from the glue gun head 11. The display screen 22 is connected to the handle 12 or the glue gun barrel 13.

[0047] When using the glue application gun 100, the operator holds the handle 12, which improves the operator's comfort. The glue application gun barrel 13 is the outer shell of the glue application gun 100 and provides protection.

[0048] The display screen 22 can be connected to the handle 12, or it can be connected to the glue gun barrel 13. The handle 12 and the glue gun barrel 13 are close to the operator relative to the glue gun head 11. By connecting the display screen 22 to the handle 12 or to the glue gun barrel 13, the display screen 22 can be positioned close to the operator, allowing the operator to observe the image on the display screen 22 more clearly.

[0049] Furthermore, the grip 12 and the glue gun barrel 13 have strong structural stability. Connecting the display screen 22 to the grip 12 or to the glue gun barrel 13 helps to improve the installation stability of the display screen 22.

[0050] In some embodiments of the present invention, such as Figure 1 As shown, the glue gun 100 also includes a snap-fit ​​component 3, and the display screen 22 is connected to the glue gun tube 13 via the snap-fit ​​component 3.

[0051] When the operator uses the glue gun 100, he holds the handle 12. Therefore, the display screen 22 is mounted on the glue gun barrel 13, which can reduce the interference between the operator holding the glue gun 100 and the display screen 22, and make it easier for the operator to observe the image on the display screen 22.

[0052] By using the snap-fit ​​connector 3 to connect the display screen 22 to the glue gun barrel 13, it is easy to assemble and disassemble the display screen 22 and the glue gun barrel 13. This not only improves the assembly efficiency of the display screen 22 and the glue gun barrel 13, but also allows the display screen 22 to be removed from the glue gun body 1, making it easier to replace or maintain the glue gun body 1.

[0053] Of course, it is not limited to this. The display screen 22 can also be fixedly connected to the glue gun barrel 13 to improve the installation stability of the display screen 22, reduce the shaking of the display screen 22, and help improve the stability of the image displayed on the display screen 22.

[0054] In some embodiments of the present invention, such as Figure 5 As shown, the snap-fit ​​component 3 includes: a fixed base 31 and an elastic buckle 32. The fixed base 31 defines a limiting groove, and the display screen 22 is installed in the limiting groove. The elastic buckle 32 is connected to the side of the fixed base 31 opposite to the limiting groove. There are two elastic buckles 32, which are arc-shaped and have their free ends spaced apart. The elastic buckle 32 clamps the glue gun barrel 13.

[0055] The connector 3 includes a fixing base 31, which is used to support the display screen 22 and limit the position of the display screen 22. The fixing base 31 defines a limiting groove, and the display screen 22 is installed in the limiting groove, which can improve the installation stability of the display screen 22, reduce the shaking of the display screen 22, and help improve the stability of the image displayed on the display screen 22.

[0056] The elastic buckle 32 is used to connect with the glue gun barrel 13. Setting the elastic buckle 32 on the side of the fixed base 31 away from the limiting groove can reduce the interference to the display screen 22 when the elastic buckle 32 is connected to the glue gun barrel 13, and can also reduce the obstruction of the display screen 22.

[0057] Two elastic clips 32 are arc-shaped. The elastic clips 32 use elastic force to firmly clamp the elastic clip 32 to the glue application gun barrel 13, thus ensuring a stable connection between the snap-fit ​​component 3 and the glue application gun barrel 13. The free ends of the two elastic clips 32 are spaced apart, and the elastic deformation of the elastic clips 32 allows the gap between the free ends of the elastic clips 32 to accommodate the glue application gun barrel 13, thereby enabling convenient assembly and disassembly of the snap-fit ​​component 3 and the glue application gun barrel 13.

[0058] In some embodiments of the present invention, the free ends of the two elastic clips 32 are connected by fasteners. When it is necessary to stably connect the clip 3 to the glue gun barrel 13, the fasteners tighten the two elastic clips 32, so that the elastic clips 32 stably clamp the glue gun barrel 13, thereby stably connecting the display screen 22 to the glue gun barrel 13. When it is necessary to change the position of the display screen 22, the fasteners are loosened, so that the two elastic clips 32 can move relative to the glue gun barrel 13. Thus, the clip 3 can be moved along the length of the glue gun barrel 13, thereby changing the installation position of the display screen 22. When it is necessary to remove the display screen 22 from the glue gun barrel 13, the fasteners are removed from the elastic clips 32, and the gap between the free ends of the elastic clips 32 is made to allow the glue gun barrel 13 to pass through, thereby separating the clip 3 from the glue gun barrel 13.

[0059] In some embodiments of the present invention, the display screen 22 is connected to the glue gun barrel 13, and the distance between the display screen 22 and the grip 12 is 300-500mm.

[0060] When the operator uses the glue gun 100, he holds the handle 12. Therefore, the display screen 22 is mounted on the glue gun barrel 13, which can reduce the interference between the operator holding the glue gun 100 and the display screen 22, and make it easier for the operator to observe the image on the display screen 22.

[0061] When the distance between the display screen 22 and the handle 12 is too close, the operator will obstruct the display screen 22 when holding the handle 12, resulting in poor observation. In addition, the operator's hand movements may be affected when trying to observe the display screen 22, which will increase the difficulty of operation and reduce work efficiency. When the distance between the display screen 22 and the handle 12 is too far, it will increase the difficulty of observation and also reduce the efficiency of operation.

[0062] Therefore, in some embodiments of the present invention, the distance between the display screen 22 and the grip 12 is preferably designed to be 300-500mm, so that the operator can clearly observe the image on the display screen 22 while holding it in a normal operating posture. This allows for simultaneous gripping and screen observation, achieving a synergistic effect between fine hand operation and comfortable eye monitoring, which is beneficial to improving the efficiency of adhesive application.

[0063] Optionally, the distance between the display screen 22 and the grip 12 can be 300mm, 350mm, 400mm, 450mm or 500mm, etc.

[0064] In some embodiments of the present invention, the glue gun barrel 13 is provided with a sliding groove extending along the length direction of the glue gun barrel 13, and the display screen 22 is slidably disposed in the sliding groove; the glue gun 100 also includes a locking mechanism, which is used to limit the movement of the display screen 22.

[0065] The display screen 22 is slidably positioned relative to the glue gun barrel 13, allowing the operator to adjust the distance between themselves and the display screen 22 as needed. Operators can adjust the position of the display screen 22 according to their own usage habits, improving ease of use and enhancing the clarity of the display screen 22 for observation.

[0066] By providing a sliding groove extending along the length direction on the glue gun barrel 13, the movement reliability of the display screen 22 can be improved by moving the display screen 22 relative to the sliding groove.

[0067] The glue gun 100 also includes a locking mechanism, which can limit the movement of the display screen 22, thereby locking the display screen 22 relative to the glue gun tube 13. The display screen 22 can be locked at any position during its movement along the slide, which facilitates the adjustment of the position of the display screen 22. The connection stability of the display screen 22 when locked by the locking mechanism is strong, which can reduce the shaking of the display screen 22 and help improve the stability of the image displayed on the display screen 22.

[0068] In some embodiments of the present invention, the locking mechanism is a claw connected to the glue gun barrel 13, which can lock and limit the movement of the slider, thereby fixing the display screen 22 relative to the glue gun barrel 13.

[0069] In other embodiments of the present invention, the display screen 22 is connected to the glue gun barrel 13 via a flexible shaping support arm, which can be bent in any direction and maintain the bent shape.

[0070] In this way, the display screen 22 can be moved relative to the glue gun barrel 13, thereby adjusting its position relative to the operator. The operator can adjust the position of the display screen 22 according to their own usage habits, improving ease of use and enhancing the clarity of the operator's observation of the display screen 22.

[0071] Furthermore, the flexible shaping arm can maintain its bent position, resulting in greater stability of the display screen 22, reducing its wobbling and improving the stability of the displayed image. It also eliminates the need for additional positioning components to hold the display screen 22 in place, simplifying the structure and reducing manufacturing costs.

[0072] In some embodiments of the present invention, the glue gun body 1 is provided with a folding mechanism for storing the display screen 22. When glue application is not required to be monitored using a visual component, the operator can fold the display screen 22 close to the glue gun body 1 using the folding mechanism, reducing the overall space occupation and facilitating operation or storage in narrow spaces; when needed, the display screen 22 can be unfolded to a position that is easy to observe, realizing flexible use in multiple working conditions.

[0073] In some embodiments of the present invention, the visual component 2 further includes a battery, which is integrated with the display screen 22 and connected to the camera 21 wiring harness.

[0074] By integrating the battery with the display screen 22, the battery can be used to directly power the display screen 22 and the camera 21, which reduces the introduction of external wiring harnesses and reduces interference to the operation of the glue gun 100.

[0075] In some embodiments of the present invention, the battery is designed with large capacity and long battery life, which can meet the needs of long-term continuous glue application operations, reduce production interruptions caused by frequent battery replacements, and improve overall production efficiency.

[0076] In some embodiments of the present invention, the visual component 2 further includes a switch, which is disposed on the side of the housing of the display screen 22, or integrated with the display screen 22 as a touch-sensitive virtual switch. The switch is connected in series in the power supply circuit of the battery, camera 21, and display screen 22, and is used to control the power supply and de-energization of the camera 21 and the display screen 22. In this way, the operator can conveniently turn the entire visual component 2 on or off with one hand, without cumbersome operation, and effectively avoids wasting power due to the continuous operation of the camera and screen during non-adhesive application periods.

[0077] In some other embodiments of this application, the switch can also be located on the handle 12 of the glue gun body 1, in a position easily accessible to the operator's fingers when holding the gun normally. This allows the operator to control the working state of the visual components without interrupting their work posture by pressing or tossing the switch while holding and operating the glue gun with one hand, further reducing interference and improving operational smoothness.

[0078] In some embodiments of the present invention, the display screen 22 is connected to the glue gun barrel 13 via a mounting base, and the display screen 22 and the mounting base are rotatably connected via a ball joint.

[0079] In this way, the display screen 22 can rotate relative to the glue gun barrel 13, and the operator can adjust the orientation angle of the display screen 22 according to their own usage habits, which helps to improve the clarity of the operator's observation of the display screen 22.

[0080] In other embodiments of the present invention, the display screen 22 may be flipped or mirrored. When the operator holds the glue gun 100 from an unconventional angle due to limitations in the glue application orientation, resulting in the image captured by the camera 21 being inconsistent with the operator's natural viewing angle, flipping or mirroring the image can make the direction displayed on the display screen 22 consistent with the operator's intuitive direction, reducing the risk of misoperation caused by misalignment.

[0081] In some embodiments of the present invention, the visual component 2 further includes at least one illumination lamp, which is positioned close to the camera 21 and projects light toward the dispensing area of ​​the dispensing port 111. In low-light operating environments, the illumination lamp provides auxiliary lighting for the camera 21, enabling the display screen 22 to display a bright, high-contrast image, allowing the operator to clearly see the dispensing path and the shape of the adhesive strip, thus improving operational reliability.

[0082] In some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the glue gun body 1 includes a glue gun barrel 13 and a glue delivery tube 14. The glue delivery tube 14 is connected between the end of the glue gun barrel 13 and the glue gun head 11. The glue delivery tube 14 includes a first section 141 and a second section 142 connected together. The first section 141 extends along the length direction of the glue gun barrel 13, and the second section 142 is connected to the glue gun head 11 and is bent and connected to the first section 141.

[0083] The glue application gun body 1 includes a glue application gun barrel 13 and a glue delivery tube 14. The glue delivery tube 14 is connected to the glue application gun head 11 and is used to deliver glue to the glue application gun head 11. The glue application gun barrel 13 is covered by the glue delivery tube 14. The glue application gun barrel 13 has high structural strength, which can protect the glue delivery tube 14 and improve the working reliability of the glue application gun body 1.

[0084] By setting the glue delivery tube 14 to have a first section 141 and a second section 142 that bends to each other, the glue application gun head 11 connected to the second section 142 can be extended into a position that is not visible to the operator. With the help of the visual component 2, the glue application operation can be performed on the weld stop in a position that is not visible to the operator.

[0085] The structure and operation of a specific embodiment of the present invention are described below with reference to the accompanying drawings.

[0086] The glue applicator 100 includes a glue applicator body 1 and a visual component 2. The glue applicator body 1 includes a handle 12, a glue applicator tube 13, and a glue applicator head 11. The glue applicator head is installed at the end of the glue applicator tube 13, and the handle 12 is connected to the other end of the glue applicator tube 13 away from the glue applicator head 11. The visual component 2 is installed on the glue applicator body 1 and includes a camera 21 and a display screen 22. The camera 21 is positioned close to the glue applicator head 11 and facing the glue outlet 111 of the glue applicator head 11. The camera 21 and the display screen 22 are connected by a signal transmission line. The signal transmission line passes through the glue applicator tube 13 to connect the camera 21 and the display screen 22. The display screen 22 is used to receive and display the video information collected by the camera 21 in real time.

[0087] This invention uses an example of a vehicle model whose structure is such that the weld joint between the rear panel and the rear floor cannot be visually inspected due to the downward tilting structure of the door, which makes manual application of adhesive impossible.

[0088] When applying adhesive to the weld seam between the rear panel and the rear floor, which is not directly visible to the operator, the operator must first firmly grip the handle 12 of the adhesive application gun 100. After picking up the adhesive application gun 100, the operator slowly moves it to the predetermined position near the weld seam of the rear panel.

[0089] Then, the equipped display screen 22 is turned on. The display screen 22 captures and displays video information in real time through the camera 21. With the help of this clear information, the operator can accurately align the glue gun head 11 of the glue gun 100 with and place it on the stop that cannot be directly seen. By lightly squeezing the handle 12, the operator can flexibly turn the glue application function on or off.

[0090] When the adhesive application function is turned on, the adhesive will flow smoothly through the adhesive delivery pipe 14 and through the adhesive application gun head 11, and be evenly applied to the stop of the weld between the rear panel and the rear floor.

[0091] Throughout the adhesive application process, the operator can still carefully observe the specific status of the previous adhesive application through the real-time information provided on the display screen 22 to ensure that the adhesive can completely and without omission cover the entire stop. After the stop is completely coated, when the adhesive application is completed, the operator can also conduct a comprehensive adhesive quality inspection through the display screen 22 to carefully check for any adhesive defects, so as to determine in time whether rework is required.

[0092] Furthermore, the display screen 22 is securely fixed to a dedicated mounting clip, ensuring it will not shift during use. When the battery needs to be replaced, the operator can easily remove the display screen 22 and quickly replace the old battery on the back, thus ensuring the continuous and efficient operation of the equipment.

[0093] During operation, the video information displayed on the screen 22 is high-definition and real-time, enabling operators to accurately control the glue application process even in complex environments. Meanwhile, the overall design of the glue gun 100 conforms to ergonomic principles; the shape and material of the handle 12 are carefully chosen to ensure operator comfort during extended use, effectively reducing workload. The glue gun barrel 13 is meticulously designed to ensure both a reasonable layout of the internal signal transmission lines and glue delivery tube 14, and the overall structural stability.

[0094] The glue application gun head 11 is made of a special material, possessing excellent wear resistance and corrosion resistance. It can adapt to the coating needs of different types of adhesives and ensures the uniformity of the adhesive during the coating process. The signal transmission line has good anti-interference capabilities, ensuring that video information is not distorted or delayed during transmission, providing operators with accurate and reliable visual feedback.

[0095] The battery features a large capacity and long battery life design, which can meet the needs of long-term continuous gluing operations, reduce production interruptions caused by frequent battery replacements, and improve overall production efficiency.

[0096] The ingenious design of the fixing clips not only securely fixes the display screen 22, but also allows operators to quickly disassemble and install it when needed, facilitating equipment maintenance and upkeep.

[0097] Furthermore, the glue application gun 100 of this invention demonstrates strong adaptability to different vehicle models and complex structures. Since the position and shape of the weld seam between the rear bumper and rear floor may vary between different vehicle models, this glue application gun 100, with its flexible operation and precise positioning capabilities, can quickly adapt to various changes. Operators only need to fine-tune the angle and position of the glue application gun 100 according to the actual situation to ensure that the glue application gun head 11 accurately overlaps the weld seam, achieving high-quality glue application.

[0098] In terms of the production environment, this glue gun 100 also fully considers the diversity of actual working conditions. Whether in a well-lit workshop or a dimly lit corner, the high-definition video information on the display screen 22 provides operators with clear visual feedback. Even in environments with dust or slight oil contamination, the display screen 22 and camera 21 can maintain good working condition, ensuring the accuracy and real-time nature of the video information.

[0099] Furthermore, the glue applicator 100 is very easy to maintain and service. Besides the aforementioned fixing clips that facilitate the disassembly and installation of the display screen 22, other components such as the glue delivery tube 14 and the glue applicator head 11 also adopt a modular design, making it convenient for operators to replace and clean them. This design not only extends the service life of the glue applicator 100 but also reduces maintenance costs, further improving production efficiency.
