Description

Technical Field

[0001] This utility model relates to the field of Tin coating technology, specifically to a coating device for Tin coating. Background Technology

[0002] In modern industrial manufacturing, tin coating technology is widely used in electronic components, precision parts, and aerospace due to its excellent conductivity, corrosion resistance, and weldability. However, existing tin coating equipment still has many shortcomings in practical applications, hindering further improvements in efficiency and accuracy. Traditional coating equipment typically employs a fixed-station design, lacking flexibility and failing to adapt to the needs of workpieces of different shapes and sizes, resulting in poor coating uniformity and consistency. Furthermore, existing equipment relies heavily on manual operation or simple mechanical structures for workpiece positioning and clamping, which is not only inefficient but also prone to coating deviations due to human error, affecting product quality.

[0003] Meanwhile, during the coating process, the relative position adjustment between the spraying device and the workpiece is often not precise enough, and there is a lack of automated control methods, resulting in uneven coating thickness or frequent localized missed coatings. Especially in coating complex curved surfaces or irregularly shaped workpieces, existing technologies struggle to achieve precise area positioning and masking protection, making non-target areas prone to mis-coating, increasing the difficulty and cost of subsequent processing. On the other hand, if the heat and volatile substances generated during the coating process are not dissipated and treated in a timely manner, they may adversely affect coating quality and the operating environment. Therefore, developing a device capable of efficient, precise, and automated coating to solve the above-mentioned technical problems has become a key direction urgently needing breakthroughs in the current Tin coating technology field. Utility Model Content

[0004] This utility model relates to the field of tin coating technology, specifically a coating device for tin coating. Addressing the problems of low coating accuracy, complex operation, and coating quality degradation due to heat accumulation in existing technologies, this utility model proposes a coating device with a reasonable structure, convenient operation, and high efficiency.

[0005] This utility model provides a coating device for Tin coating, including a base, a workstation, a coating system, a heat dissipation system, a rotating shielding system, and an automated control system, wherein:

[0006] The base serves as the fundamental support for the entire device. A workstation seat is fixed to its top with bolts. The workstation seat is used to place the workpiece to be coated.

The rack meshes with the drive gear, and the sliding adjustment of the clamping block is realized through gear and rack transmission. A clearance groove is opened on one side of the support base to provide space for the movement of the rack.

[0012] Specifically, the automated control system includes a servo drive system, which is used to drive the sliding of the column, beam, and mounting base. The servo drive system controls the motion trajectory and speed of each component through a preset program to achieve automated adjustment of multiple degrees of freedom. Furthermore, the servo drive system can automatically calculate the spraying path according to the shape and size of the workpiece, and adjust the position and angle of the spraying device through real-time feedback to ensure the efficiency and accuracy of the coating process.

[0013] The technical solution of this utility model achieves the following specific details of its innovative points:

[0018] Through the above technical solution, this utility model achieves the following technical effects:

[0019] First, the design of the multi-degree-of-freedom adjustment mechanism allows the spraying device to flexibly adjust its position in three-dimensional space to adapt to the coating needs of workpieces of different shapes and sizes. Second, the coordinated design of the precise positioning and clamping system effectively avoids uneven coating caused by workpiece movement. Third, the design of the rotating mask protects the parts of the workpiece that do not need to be sprayed by adjusting the masking area, improving the flexibility and accuracy of coating. Finally, the introduction of the efficient heat dissipation system reduces the heat generated during the spraying process, ensuring coating quality and normal operation of the equipment.

[0031] This invention provides a coating device for Tin coatings, the structure and function of which are designed to solve the problems of low coating accuracy, complex operation, and coating quality degradation due to heat accumulation in existing technologies. The following is in conjunction with the appendix... Figure 1To be continued Figure 6 The specific embodiments of this utility model will be described in detail.

[0032] The overall structure of this utility model is as follows: Figures 1 to 6 As shown, the system includes a base 1, a workstation 2, a coating system, a heat dissipation system, a rotating shielding system, and an automated control system. The base 1 serves as the fundamental support for the entire device, with the workstation 2 bolted to its top. The top of the workstation 2 is equipped with a contour positioning block 3 and a clamping block 6. The contour positioning block 3 is fixed to the workstation 2 with screws and is symmetrically arranged to ensure accurate positioning of the workpiece during the coating process. The clamping block 6 is slidably mounted on the top of the workstation 2 and is slidably connected to the workstation 2 via a slide groove 18. The slide groove 18 is symmetrically arranged on the top of the workstation 2, allowing the clamping block 6 to be adjusted horizontally within the slide groove 18 to accommodate workpieces of different sizes. Furthermore, a side plate 12 is welded to one side of the clamping block 6, and a rack 13 is fixed to one end of the side plate 12 with screws. The rack 13 meshes with a drive gear 14, enabling precise adjustment of the clamping block 6 through rack and pinion transmission. This structural design allows the clamping block 6 to be finely adjusted according to the actual shape and size of the workpiece, ensuring that the workpiece remains stable throughout the coating process.

[0033] A clearance groove 11 is provided on one side of the support base 41, and the center of the clearance groove 11 is on the same axis as the center of the rack 13.

[0034] The core components of the coating system include a column 100, a crossbeam 200, a mounting base 7, a storage tank 8, and a spraying device 10. The column 100 is vertically mounted on the base 1 and its position can be adjusted along the length of the base 1 by sliding. The crossbeam 200 is horizontally mounted on the column 100 and can slide up and down along the column 100 to adjust the vertical position of the spraying device 10. The mounting base 7 is slidably mounted on the crossbeam 200 and can slide left and right along the crossbeam 200, thereby achieving precise positioning of the spraying device 10 in three-dimensional space. The spraying device 10 includes a spray cylinder and a nozzle. The nozzle is fixedly mounted on the bottom of the spray cylinder and is used to uniformly spray the Tin coating material onto the workpiece surface. The storage tank 8 is connected to the spraying device 10 through a pipeline, providing a stable supply of coating material to the spraying device 10. This multi-degree-of-freedom adjustment mechanism allows the spraying device 10 to move flexibly in the X, Y, and Z directions to meet the coating requirements of workpieces of different shapes and sizes.

[0035] The heat dissipation system consists of a cooling fan 9, which is fixedly installed on one side of the mounting base 7, next to the spraying device 10. The cooling fan 9 reduces the heat generated during the spraying process by forcing airflow, preventing coating quality degradation or equipment malfunction due to high temperatures. The airflow and direction of the cooling fan 9 can be adjusted according to actual needs to meet the heat dissipation requirements of different workpieces and process conditions. For example, when coating a large area workpiece, the cooling fan 9 can increase the airflow and adjust the airflow direction to ensure the temperature of the sprayed area is maintained within a reasonable range; while when coating small workpieces, the airflow can be appropriately reduced to avoid excessive cooling affecting coating adhesion.

[0036] The design of the rotating masking system further enhances the functionality and flexibility of the coating apparatus. For example... Figure 1 and Figure 4 As shown, the rotating shield system includes a support base 41, a pin, a rotating shield 4, a bevel gear set, a rack 13, and a drive gear 14. The support base 41 is fixed to one side of the top of the workstation 2 with countersunk screws for mounting the pin. The rotating shield 4 is fixedly sleeved on the outside of the pin, and the rotating shield 4 has area positioning holes 5 for marking the shielded area. A first bevel gear 16 is fixedly sleeved on one end of the pin, and the first bevel gear 16 meshes with a second bevel gear 17. The second bevel gear 17 is fixedly sleeved on a rotating shaft 15, and drive gears 14 are fixedly sleeved on the outside of the rotating shaft 15. The rack 13 meshes with the drive gear 14 through a rack and pinion transmission. When the rack 13 moves, the drive gear 14 drives the rotating shaft 15 to rotate, which in turn drives the pin and the rotating shield 4 to rotate through the bevel gear set. The rotation angle and shielded area of ​​the rotating shield 4 can be adjusted according to the actual needs of the workpiece, thereby protecting the parts of the workpiece that do not need to be painted. A clearance groove 11 is provided on one side of the support base 41 to provide space for the movement of the rack 13, while ensuring that the rotation of the rotating cover 4 is smooth and unobstructed.

[0037] The automated control system consists of a servo drive system, which drives the sliding of the column 100, crossbeam 200, and mounting base 7. The servo drive system controls the movement trajectory and speed of each component through a preset program, achieving automated adjustment with multiple degrees of freedom. For example, when coating a specific workpiece, the servo drive system can automatically calculate the spraying path based on the workpiece's shape and size, and adjust the position and angle of the spraying device 10 through real-time feedback to ensure the efficiency and precision of the coating process. Furthermore, the servo drive system can also be linked with the cooling fan 9, dynamically adjusting the operating parameters of the cooling fan 9 based on the heat generated during the spraying process to achieve optimal heat dissipation.

[0038] The specific operating principle and process of this utility model are as follows: First, the workpiece to be coated is placed on the workstation 2, and the workpiece is accurately positioned and stably clamped by the contour positioning block 3 and the clamping block 6. The position of the clamping block 6 can be finely adjusted by gear and rack transmission to adapt to workpieces of different sizes and shapes. Subsequently, the servo drive system is started, and the servo drive system controls the movement of the column 100, the crossbeam 200 and the mounting base 7 according to the preset program, so that the spraying device 10 moves to the initial spraying position. During the coating process, the storage tank 8 provides coating material to the spraying device 10 through pipelines, and the nozzle sprays the coating material evenly onto the surface of the workpiece. At the same time, the cooling fan 9 reduces the heat generated during the spraying process by forced airflow, ensuring coating quality and normal equipment operation. If there are areas on the workpiece that do not need to be sprayed, the shielding area of ​​the rotating shielding plate 4 can be adjusted by the rotating shielding plate system to protect these areas from being covered by the coating material. The rotation of the rotating shielding plate 4 is driven by a bevel gear set, which is linked to the clamping block 6 through gear and rack transmission to ensure that the shielding area is adjusted synchronously with the clamping position.

[0039] Through the above technical solutions, this utility model achieves the following technical effects: the design of the multi-degree-of-freedom adjustment mechanism enables the spraying device 10 to flexibly adjust its position in three-dimensional space, adapting to the coating needs of workpieces of different shapes and sizes; the coordinated design of the precise positioning and clamping system effectively avoids the problem of uneven coating caused by workpiece movement; the design of the rotating mask protects the parts of the workpiece that do not need to be sprayed by adjusting the masking area, improving the flexibility and accuracy of coating; the introduction of the high-efficiency heat dissipation system reduces the heat generated during the spraying process, ensuring coating quality and normal operation of the equipment. In summary, this utility model, through reasonable structural design and functional integration, solves the problems of low coating accuracy, complex operation, and coating quality degradation caused by heat accumulation in the prior art, and has high practicality and promotional value.

[0040] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
