Description

A primer coating device for corner window glass processing Technical Field

[0001] This utility model relates to the field of glass processing technology, specifically to a primer coating device for processing corner window glass. Background Technology

[0002] Corner window glass is widely used as an important component in modern automobile manufacturing and architectural decoration. Before subsequent processes such as coating and bonding, corner window glass usually needs to be primed. The purpose of priming is to improve the adhesion between the glass surface and the subsequent coatings or adhesives, thereby ensuring the overall quality and performance of the product.

[0003] Currently, there are various methods for applying primer to corner window glass. Early on, many manufacturers used manual brushing for primer application. In this method, workers would hold a brush, dip it in the primer, and then apply it to the corner window glass surface. This method has several drawbacks. First, because workers' techniques and pressure are inconsistent, the primer coating thickness on the glass surface is uneven, affecting the subsequent coating or bonding effects and potentially causing coating peeling or weak adhesion. Second, manual operation is inefficient, making it difficult to meet the needs of large-scale production, and the high labor costs increase the company's production costs.

[0004] With technological advancements, some companies have begun adopting automated primer coating equipment. However, most existing automated primer coating equipment is designed for ordinary flat glass and is poorly suited for irregularly shaped corner windows. Corner windows typically have complex geometries, making it difficult for existing automated equipment to accurately and evenly apply primer to their edges and corners. While some equipment can apply primer to glass, it lacks effective adjustment mechanisms when dealing with corner windows of different sizes and shapes, making it impossible to flexibly adjust the position and range of the primer application. This results in poor primer coating effects, with blind spots or wasted primer. Furthermore, existing primer coating equipment also has shortcomings in the delivery and distribution of primer, making it difficult to precisely control the amount used. This easily leads to problems of too much or too little primer; too much causes waste and contamination, while too little fails to achieve a good primer coating effect.

[0005] Therefore, there is an urgent need for a base coating device for corner window glass processing that can adapt to the complex shape of corner window glass, precisely control the amount of base coating agent, and improve the efficiency and quality of base coating, so as to meet the needs of modern production. Summary of the Invention

A third electric cylinder is fixedly connected to the top of the base plate. The output end of the third electric cylinder is fixedly connected to the movable plate.

[0011] In a preferred embodiment of this invention, a glue storage cylinder is fixedly connected to the top of the base plate via a bracket, and a delivery pump is connected to the bottom of the glue storage cylinder. The delivery pump and the nozzle are connected via a pipeline.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model employs a movable frame that can move back and forth on the top of the base plate, which, in conjunction with a first motor driving a threaded rod, enables precise back-and-forth movement of the support plate and clamping assembly.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] As shown in Figures 1 to 4, a primer coating device for corner window glass processing includes a base plate 1. A drive box 2 is fixedly connected to the top of the base plate 1 via a bracket. A threaded rod 3 is rotatably connected inside the drive box 2. A movable frame 4 is slidably connected inside the drive box 2 and threadedly connected to the threaded rod 3. A first motor 5 is fixedly connected to the front of the drive box 2, and the output end of the first motor 5 is fixedly connected to the threaded rod 3. A groove is provided on the right side of the movable frame 4, and a sliding column 6 is slidably connected inside the groove. A mounting bracket 7 is fixedly connected to the right side of the sliding column 6. A first electric cylinder 8 is fixedly connected to the right side of the moving frame 4. The output end of the first electric cylinder 8 is fixedly connected to the mounting frame 7. A support plate 9 is fixedly connected to the right side of the mounting frame 7. A clamping assembly 10 is provided on the surface of the support plate 9. A lifting assembly 11 is provided on the top of the base plate 1. A support block 12 is provided above the lifting assembly 11. A spraying frame 13 is rotatably connected inside the support block 12. A second motor 15 is fixedly connected to the right side of the support block 12. The output end of the second motor 15 is fixedly connected to the spraying frame 13. A spray nozzle 14 is fixedly connected to the left side of the spraying frame 13.

[0023] Referring to Figure 3, the clamping assembly 10 includes a second electric cylinder 16 fixedly connected to the top and bottom of the right side of the support plate 9. The output end of the second electric cylinder 16 is fixedly connected to a clamping plate 17, which is in contact with the support plate 9.

[0024] As a technical optimization of this utility model, the clamping assembly 10 employs a structure design where the second electric cylinder 16 drives the clamping plate 17. This allows for flexible adjustment based on the size of the corner window glass, ensuring that the clamping force of the clamping plate 17 on the glass is moderate and uniform. This design effectively solves the problem of insecure fixing in traditional primer coating devices when processing glass of different sizes, preventing displacement or shaking of the glass during the primer coating process, thereby ensuring the accuracy and stability of the primer coating. The rubber pad 18 fixed to the surface of the clamping plate 17 and its anti-slip texture design further enhance the friction with the glass surface, preventing damage to the glass during clamping and improving the reliability of clamping. Through this clamping assembly 10, the device can adapt to various specifications of corner window glass, expanding the scope of application of the equipment, improving production efficiency, reducing primer coating quality problems caused by improper glass fixing, and saving production costs for enterprises.

[0025] Referring to Figure 3, a rubber pad 18 is fixedly connected to the surface of the clamping plate 17. The surface of the rubber pad 18 is provided with anti-slip texture, and there are several anti-slip textures. The rubber pad 18 is attached to the support plate 9.

[0026] As a technical optimization of this utility model, the rubber pad 18 and its anti-slip texture structure provided on the surface of the clamping plate 17 have multiple beneficial effects. First, the elastic properties of the rubber pad 18 effectively buffer the clamping force of the clamping plate 17 on the glass, preventing scratches or breakage caused by rigid contact and protecting the integrity and surface quality of the glass. Second, the anti-slip texture design significantly increases the friction between the rubber pad 18 and the glass surface, ensuring the glass is firmly fixed during the primer coating process. Even when the spray nozzle 14 performs multi-angle spraying or moves, the glass will not shift, ensuring the accuracy of the primer coating. Furthermore, the material of the rubber pad 18 has a certain degree of chemical corrosion resistance, resisting the erosion of the primer, extending the service life of the clamping plate 17, and reducing equipment maintenance costs. In addition, this anti-slip structure can adapt to glass with different surface roughness, improving the versatility of the device and enabling it to better meet diverse production needs.

[0027] Referring to Figure 1, the lifting assembly 11 includes a sleeve 19 fixedly connected to the front and rear sides of the top of the base plate 1. A movable column 20 is slidably connected inside the sleeve 19. A movable plate 22 is fixedly connected to the top of the movable column 20. The movable plate 22 is fixedly connected to the support block 12. A third electric cylinder 21 is fixedly connected to the top of the base plate 1. The output end of the third electric cylinder 21 is fixedly connected to the movable plate 22.

[0028] As a technical optimization of this utility model, the lifting assembly 11 employs a sliding structure between the sleeve 19 and the movable column 20, and the movable plate 22 is raised and lowered by the third electric cylinder 21, achieving stable vertical adjustment of the support block 12 and the spray head 14. This design allows the device to be flexibly adjusted according to the height of the corner window glass, thereby ensuring uniform distribution of the primer. The stability design of the lifting assembly 11 effectively avoids uneven primer thickness caused by equipment shaking during spraying, improving the consistency of primer quality. Simultaneously, the structure is simple and reliable, easy to maintain and operate, reducing equipment failure rate and improving production efficiency. By precisely controlling the height of the spray head 14, the device can adapt to corner window glass of different specifications, expanding the applicability of the equipment and providing enterprises with a more flexible production solution.

[0029] Referring to Figure 1, a glue storage cylinder 23 is fixedly connected to the top of the base plate 1 by a bracket, and a delivery pump 24 is connected to the bottom of the glue storage cylinder 23. The delivery pump 24 and the nozzle 14 are connected by a pipe.

[0030] As a technical optimization of this utility model, the system of the glue storage tank 23 and the delivery pump 24 achieves stable supply and precise control of the primer. The large-capacity design of the glue storage tank 23 reduces the frequent addition of primer, improves production efficiency, and ensures the continuity of primer during the spraying process. The use of the delivery pump 24 can precisely control the delivery amount of primer according to the spraying requirements, avoiding the problems of too much or too little primer in traditional equipment, thus reducing waste and ensuring the primer effect. The pipeline connection method ensures that the primer can be smoothly delivered from the glue storage tank 23 to the nozzle 14, avoiding problems such as blockage or leakage, and improving the reliability of the equipment. In addition, the system is easy to clean and maintain, and can replace different types of primer in a timely manner to adapt to diverse production needs, providing enterprises with more convenient and efficient production support. The delivery pump 24 is a metering pump, which can precisely control the delivery amount. The aforementioned delivery pump 24 is a common existing technology and will not be described in detail in this application.

[0031] Referring to Figure 2, a bearing is fixedly connected inside the drive box 2, and the outer ring of the bearing is fixedly connected to the drive box 2, while the inner ring of the bearing is fixedly connected to the threaded rod 3.

[0032] As a technical optimization of this utility model, a bearing structure installed inside the drive box 2 provides stable support for the rotation of the threaded rod 3, reducing frictional resistance during rotation and improving the rotational efficiency and service life of the threaded rod 3. The outer ring of the bearing is fixedly connected to the drive box 2, and the inner ring is fixedly connected to the threaded rod 3. This structural design ensures the stability of the threaded rod 3 during high-speed rotation and avoids the problem of decreased transmission accuracy due to shaking or offset. By improving the rotational accuracy of the threaded rod 3, the movement of the movable frame 4 is more stable and precise, thereby ensuring the positioning accuracy of the nozzle 14 in the horizontal direction and further improving the quality and consistency of the primer. In addition, the use of bearings also reduces noise and vibration during equipment operation, improves the working environment, reduces the frequency and cost of equipment maintenance, and improves the overall performance and reliability of the equipment.

[0033] The working principle and usage process of this utility model are as follows: First, place the corner window glass to be primed between two clamping plates 17. Activate the second electric cylinder 16 in the clamping assembly 10 to bring the upper and lower clamping plates 17 closer together until they firmly clamp the glass. Next, based on the height of the corner window glass, drive the lifting assembly 11 via the third electric cylinder 21 to adjust the vertical height of the support block 12 and the spray nozzle 14. Then, use the first motor 5 to drive the threaded rod 3 to rotate, causing the movable frame 4, mounting frame 7, support plate 9, clamping plates 17, and corner window glass to move back and forth, ensuring the spray nozzle 14 is at a suitable distance from the glass edge. Simultaneously, the left and right positions of the mounting frame 7 can be finely adjusted via the first electric cylinder 8 to ensure accurate distance between the spray nozzle 14 and the corner window glass. Then, turn on the delivery pump 24 at the bottom of the glue storage cylinder 23 to deliver the primer to the spray nozzle 14. Finally, activate the second motor 15 to rotate the spray frame 13 and the spray nozzle 14 to a suitable angle, beginning the primer spraying of the corner window glass.

[0034] The method for spraying the corner window glass with the nozzle 14 is as follows: The first motor 5 drives the threaded rod 3 to rotate, causing the movable frame 4 to move the glass in the front-to-back direction, adjusting the front-to-back distance between the nozzle 14 and the edge of the glass; the third electric cylinder 21 drives the lifting assembly 11 to adjust the vertical height of the nozzle 14; the second motor 15 drives the spraying frame 13 to rotate, changing the spraying position of the nozzle 14. This device adjusts the position of the nozzle 14 from multiple dimensions, so that the nozzle 14 can comprehensively and evenly spray the base coat on the corner window glass. The movement of the electrical appliances in the device is controlled by an external controller and they cooperate with each other. The nozzle movement path is set by the external controller, thereby achieving a high-quality base coat on the corner window glass. The above-mentioned controller is a common existing technology and will not be described in detail in this application. The controller is not shown.
