Description

Technical Field

[0001] This utility model belongs to the field of automotive headlight adhesive coating technology, specifically relating to an adhesive coating assembly for a three-station adhesive station. Background Technology

[0002] In the automotive manufacturing industry, headlights are a key component for ensuring driving safety. Their sealing performance, structural stability, and appearance quality directly affect the vehicle's safety and market competitiveness. The headlight adhesive coating process is the core link to achieve sealed connection of various headlight components and prevent moisture and dust from penetrating. At the same time, the uniformity and aesthetics of the adhesive lines also have an important impact on the overall appearance of the headlights.

[0003] Currently, the methods for applying adhesive to automotive headlights mostly rely on manual operation or relatively simple automated equipment. However, manual application has certain drawbacks. On the one hand, adhesives usually release harmful gases, and long-term inhalation poses a great threat to the health of operators. On the other hand, manual operation makes it difficult to ensure the stability and consistency of the application, and problems such as uneven application, adhesive overflow, and incomplete sealing are very likely to occur, which seriously affect product quality. Moreover, manual application is inefficient and cannot meet the needs of large-scale, high-efficiency modern production. Utility Model Content

[0004] The purpose of this invention is to provide a coating assembly for a three-station glue station to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glue application assembly for a three-station glue station, comprising:

[0006] The base contains a first servo motor and a rotating platform is connected to the output shaft of the first servo motor. As the basic support component of the entire glue application assembly, the base can provide a stable installation platform for all the structures above. The first servo motor inside has high-precision speed and position control capabilities. When the first servo motor is working, it can drive the rotating platform to rotate within a 360-degree range, thereby driving the robotic arm and glue application assembly mounted on the rotating platform to adjust the overall working position to adapt to the glue application needs of different workstations.

[0007] A robotic arm, which is mounted on a rotating platform and includes a first joint arm connected to the rotating platform, and a second joint arm rotatably connected to the first joint arm.

[0008] The adhesive application assembly, located at one end of the robotic arm, is used to apply adhesive to the vehicle lights. The assembly includes a mounting plate and a connector connected to the mounting plate. One end of the connector is connected to a fixing plate, and a fixing post is attached to the fixing plate. A bracket is also connected to the fixing plate, and an adhesive gun is mounted on the bracket. The adhesive application assembly directly performs the adhesive application operation. The mounting plate connects the robotic arm to other components of the adhesive application assembly, ensuring the stability of the connection between the assembly and the robotic arm. The connector is made of high-strength alloy material, possessing excellent load-bearing capacity and corrosion resistance, ensuring the reliability of the connection between the fixing plate and subsequent components. The fixing post on the fixing plate enhances the structural strength of the fixing plate, preventing deformation due to stress during the adhesive application process. The adhesive gun evenly and stably applies the adhesive to the preset position of the vehicle lights, making it the core component for the adhesive application operation.

[0009] Preferably, a third joint arm is rotatably connected to the top of the second joint arm, and a fourth joint arm is rotatably connected to one end of the third joint arm, with one end of the fourth joint arm connected to the mounting plate. The rotatable connections between the second and third joint arms, and between the third and fourth joint arms, both employ precision rotating shaft structures and wear-resistant bearings, ensuring smooth rotation and high positioning accuracy between the joint arms. The fourth joint arm is connected to the mounting plate using bolt fastening, facilitating the disassembly and replacement of the mounting plate and the adhesive application assembly. Through the sequential connection and rotation of these multiple joint arms, a multi-degree-of-freedom robotic arm structure is formed, enabling flexible adjustment of the adhesive gun's spatial position and posture. This allows the adhesive gun to reach various complex adhesive application areas of the vehicle headlights, meeting the adhesive application requirements of headlights with different shapes and structures.

[0010] Preferably, the first articulated arm is provided with a second servo motor and the output shaft of the second servo motor is connected to the second articulated arm. The second servo motor is installed at a suitable position on the first articulated arm, and its output shaft is firmly connected to the second articulated arm through a coupling or other connecting parts. The second servo motor can precisely control the rotation angle and speed of the output shaft according to the instructions issued by the control system, thereby driving the second articulated arm to rotate around the connection point with the first articulated arm.

[0011] Preferably, the second articulated arm is equipped with a third servo motor, and the output shaft of the third servo motor is connected to the third articulated arm. The third servo motor is fixedly mounted on the top of the second articulated arm, and its function is to control the rotation of the third articulated arm. Similar to the second servo motor, the third servo motor also has high-precision control performance, and can accurately adjust the rotation angle and speed of the third articulated arm according to the requirements of the glue application trajectory. By controlling the third articulated arm through the third servo motor, the spatial position of the glue application gun can be further adjusted, and more complex glue application trajectories can be achieved in coordination with the movement of other articulated arms.

[0012] Preferably, the third articulated arm is equipped with a fourth servo motor and the output shaft of the fourth servo motor is connected to the fourth articulated arm. Since the fourth articulated arm is directly connected to the glue application assembly, the control of the fourth servo motor can realize the fine adjustment of the fourth articulated arm, ensuring that the glue application gun can be accurately aligned with the glue application position.

[0013] Preferably, the base has several fixed feet connected to its bottom, and reinforcing ribs connect the fixed feet to the base. The number of fixed feet is set reasonably according to the size and weight of the base, and is four in total. They are evenly distributed on the bottom edge of the base to ensure that the base is subjected to uniform force. The fixed feet are made of sturdy gray cast iron metal material and are fixed to the base by welding or bolting. The reinforcing ribs are triangular in structure and connected between the fixed feet and the base. Triangles have the characteristics of good stability and can effectively enhance the strength and rigidity of the connection between the fixed feet and the base, preventing the fixed feet from loosening or the base from deforming due to vibration or other reasons during equipment operation.

[0014] Preferably, the fixing foot is provided with a plurality of fixing holes.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) This component achieves precise control through multiple servo motors. The first servo motor in the base drives the rotating table to rotate, which can accurately adjust the overall working position. The second servo motor on the first joint arm, the third servo motor on the second joint arm, and the fourth servo motor on the third joint arm control the rotation angle of the corresponding joint arm respectively. This multi-joint collaborative control mode can make the glue gun move stably according to the preset trajectory, avoiding problems such as uneven glue dispensing and glue overflow caused by hand shaking and uneven force during manual operation. It ensures that the amount of glue and the shape of the glue line at each glue application point are highly consistent, significantly improving the sealing performance and appearance quality of the product.

[0017] (2) The installation of components such as mounting plate, fixing plate, and bracket makes the glue gun firmly and stably installed, which can adapt to the glue application needs of different models and specifications of vehicle lights. Only by changing the corresponding glue gun can the glue application operation of different products be completed, which has strong versatility and adaptability. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] This utility model provides, for example Figure 1-3 The three-station glue station glue application assembly shown includes:

[0025] Base 1, wherein a first servo motor is provided inside the base 1 and a rotating table 3 is connected to the output shaft of the first servo motor;

[0026] The robotic arm, model Yaskawa GP25, is mounted on a rotating platform 3 and includes a first joint arm 4 connected to the rotating platform 3, and a second joint arm 5 rotatably connected to the first joint arm 4.

[0027] The adhesive application assembly, located at one end of the robotic arm, is used to apply adhesive to the vehicle lights. The assembly includes a mounting plate 8 and a connector 13 connected to the mounting plate 8. One end of the connector 13 is connected to a fixing plate 10, and a fixing post 11 is connected to the fixing plate 10. A bracket 12 is also connected to the fixing plate 10, and an adhesive application gun 9 is mounted on the bracket 12. The connections between the adhesive application gun 9 and the bracket 12, the bracket 12 and the fixing plate 10, and the fixing plate 10 and the connector 13 are all detachable using bolts, clips, or other detachable connection methods. When the adhesive application gun 9 needs maintenance or replacement with a different model, simply disassembling the fasteners at the corresponding connection points allows for quick removal of the adhesive application gun 9 and related components. The operation is simple and convenient. The adhesive application gun 9 is a Nordson H20T-SOLENOID adhesive gun.

[0028] The top of the second articulated arm 5 is rotatably connected to a third articulated arm 6, and one end of the third articulated arm 6 is rotatably connected to a fourth articulated arm 7, and one end of the fourth articulated arm 7 is connected to the mounting plate 8.

[0029] The first articulated arm 4 is provided with a second servo motor 14 and the output shaft of the second servo motor 14 is connected to the second articulated arm 5.

[0030] The second articulated arm 5 is equipped with a third servo motor 15, and the output shaft of the third servo motor 15 is connected to the third articulated arm 6.

[0031] The third articulated arm 6 is equipped with a fourth servo motor 16, and the output shaft of the fourth servo motor 16 is connected to the fourth articulated arm 7.

[0032] The base 1 has several fixed feet 17 connected to its bottom, and a reinforcing rib 18 connects the fixed feet 17 to the base 1. The fixed feet 17 are provided with several fixing holes 19. The fixing holes 19 on the fixed feet 17 are the key to the fixed connection between the base 1 and the mounting surface. During installation, fasteners such as bolts and screws can be passed through the fixing holes 19 to firmly fix the fixed feet 17 to the mounting surface, thereby stably installing the entire base 1 and the adhesive application assembly in the preset position.

[0033] This three-station glue application assembly uses a base 1 as its supporting foundation. The first servo motor installed inside provides the power for overall orientation adjustment. When the working direction needs to be adjusted, the first servo motor starts, and its output end is connected to the rotary table 3, transmitting power to the rotary table 3 and causing it to rotate smoothly. The rotation of the rotary table 3 synchronously drives the first articulated arm 4 connected above and all subsequent components to change their orientation until they are aligned with the workpiece to be glued, thus establishing a basic position for subsequent glue application. One end of the first articulated arm 4 is fixed to the rotary table 3. After the rotary table 3 completes the initial orientation adjustment, the second servo motor 14 starts according to a preset command. The second servo motor 14 is installed at the end of the first articulated arm 4 furthest from the rotary table 3, and its output shaft is connected to one end of the second articulated arm 5. After starting, it drives the second articulated arm 5 to rotate around the connection point between the two. The axis rotates, and by changing the direction and duration of rotation, the second joint arm 5 can be raised, lowered, or tilted. A third servo motor 15 is installed at the end of the second joint arm 5 away from the first joint arm 4. The output shaft of the third servo motor 15 is connected to the third joint arm 6. When the third servo motor 15 is running, it will drive the third joint arm 6 to rotate around the connection point, further adjusting the overall working height and horizontal distance. A fourth servo motor 16 is installed at the end of the third joint arm 6, and its output shaft is connected to the fourth joint arm 7. The operation of the fourth servo motor 16 can drive the fourth joint arm 7 to make a final stage of fine adjustment, so that the glue gun 9 installed on the mounting plate 8 at the end of the fourth joint arm 7 can accurately approach the glue application position. Under the drive of their respective servo motors, these four joint arms make progressive position adjustments to ensure that the glue gun 9 can reach the preset glue application point.

[0034] When the glue gun 9 reaches the glue-to-be-applied position under the linkage of the multi-joint arm, it begins to dispense glue. During the glue application process, each servo motor operates continuously according to the preset glue application trajectory program. By adjusting the rotation angle of the joint arm driven by itself, the glue gun 9 is driven to move smoothly along the path where glue needs to be applied to the workpiece. During the movement, the rotation speed of the joint arm is adjusted in real time according to the glue application requirements to ensure that the glue line is continuous and uniform. When the glue application is completed, the glue gun 9 stops dispensing glue. Then, each servo motor will run in reverse according to the preset reset program, driving the corresponding joint arm to gradually return to the initial position. The rotating table 3 also rotates back to the initial position under the drive of the first servo motor, preparing for the glue application of the next workpiece and waiting for the next round of instructions to start.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
