Description

Technical Field

[0001] This utility model relates to a mobile spraying device for electroplating, belonging to the technical field of spraying equipment. Background Technology

[0002] In the electroplating industry, spray rinsing is an important step in ensuring product quality. It involves spraying water onto the product surface through spray pipes to remove residual electroplating solution and impurities.

[0003] Previously, sprinkler pipes were mostly fixed installations, limiting the range and angle of water jets and making it difficult to evenly cover the surfaces of products with complex shapes or positional deviations. To improve this situation, the industry has installed nozzles of various shapes, such as fan-shaped and conical, on the pipes to change the water jet pattern, diffusion angle, and impact force, thereby improving the rinsing power and uniformity of the products. However, because the pipes are fixed, the water jet range is still limited by the installation position and the inherent angle of the nozzles. For products with special shapes or large sizes, there are still problems with rinsing dead zones and insufficient rinsing power in some areas, affecting product quality. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a mobile spraying device for electroplating.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a mobile spraying device for electroplating, comprising...

[0006] The spray box is U-shaped, and both sides of the spray box have spray areas for cleaning the workpiece.

[0007] The spray assembly comprises multiple sets, which are slidably mounted on spray boxes on both sides of the spray area, with the spray assemblies on both sides of each spray area arranged opposite each other to spray water onto the workpiece for cleaning. Each set of spray assemblies is fixedly mounted on the rear side with a drive frame. The drive frame has an elliptical opening in the middle, and an eccentric cam is mounted inside the opening. The eccentric cam is mounted on a first rotating shaft for driving its rotation.

[0008] The system includes a drive unit and multiple transmission components. The drive unit is located below the spray box. A main drive shaft is fixedly installed on the output shaft of the drive unit. The multiple transmission components correspond to the positions of multiple spray components. The two ends of the transmission components are respectively connected to the main drive shaft and the corresponding first rotating shaft. The drive unit drives the first rotating shaft to rotate through the transmission components. When the first rotating shaft rotates, it drives the spray components to move up and down within the spray area.

[0009] Preferably, the spray assembly includes two vertically arranged and parallel mounting brackets, a spray pipe horizontally fixed between the two mounting brackets, and a plurality of nozzles evenly arranged on the spray pipe, with the two mounting brackets slidably disposed on the side wall of the spray box.

[0010] Preferably, the side wall of the spray box is provided with two slide rails corresponding to the mounting bracket, and the mounting bracket has a slider that matches the slide rail. The mounting bracket and the spray box cooperate through the slide rail and the slider.

[0011] Preferably, there are multiple spray pipes, which are evenly spaced between two mounting brackets and fixed together with the two mounting brackets. The drive frame is fixed on the multiple spray pipes.

[0012] Preferably, the mounting bracket is provided with a water supply pipe, which is connected to each spray pipe.

[0013] Preferably, the transmission assembly includes a driving gear, a driven gear, and a transmission chain. The driving gear is interference-fixed to the main drive shaft, and the driven gear is interference-fixed to the corresponding first rotating shaft. The driving gear and the driven gear are connected by the transmission chain.

[0014] Preferably, the main drive shaft is provided with a plurality of mounting seats that rotate with it, and the main drive shaft is mounted on the ground through the plurality of mounting seats.

[0015] Preferably, the output shaft of the drive device is connected to the main drive shaft via a coupling.

[0016] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0017] 1. This utility model changes the traditional fixed spray pipe mode. Through the cooperation of the drive device, transmission component, eccentric cam and drive frame, the spray component is driven to move up and down in the spray area, so that the spray range of the nozzle is no longer limited to a fixed position, and can cover a larger workpiece surface area, effectively reducing the dead corners of rinsing.

[0018] 2. Because the spray assembly can move up and down, the nozzles can spray the workpiece from different heights during the movement. For products with complex shapes or positional deviations, it can clean each part more evenly, avoiding insufficient cleaning in some areas, thus ensuring product quality.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] As attached Figure 1-2 As shown, the mobile spraying equipment for electroplating described in this utility model includes a spraying box 1, a spraying assembly 2, a driving device 4, and multiple transmission assemblies 5; wherein, the spraying box 1 is U-shaped, and both sides of the spraying box 1 have spraying areas 11 for cleaning the workpiece.

[0029] There are multiple sets of spray components 2, which are slidably arranged on the spray box 1 on both sides of the spray area 11. The spray components 2 on both sides of each spray area 11 are arranged opposite each other to spray the two sides of the workpiece and achieve water spray cleaning of the workpiece. In this embodiment, each spray area 11 is provided with two sets of spray components 2.

[0030] As attached Figure 3-4As shown, specifically, the spray assembly 2 includes two vertically arranged and parallel mounting brackets 21, a spray pipe 22 horizontally fixed between the two mounting brackets 21, and a plurality of nozzles 23 evenly arranged on the spray pipe 22. The two mounting brackets 21 are slidably arranged on the side wall of the spray box 1. Specifically, the side wall of the spray box 1 is provided with two slide rails 12 corresponding to the mounting brackets 21. The mounting brackets 21 have sliders 211 that match the slide rails 12. The mounting brackets 21 and the spray box 1 cooperate with the slide rails 12 and the sliders 211 to ensure the stability and smoothness of the spray assembly 2 during the up and down movement.

[0031] Furthermore, there are multiple spray pipes 22, which are evenly spaced between two mounting brackets 21 and fixed to the two mounting brackets 21 to ensure that all spray pipes 22 can move synchronously. A water supply pipe 212 is provided on the mounting bracket 21, and the water supply pipe 212 is connected to each spray pipe 22. External water can be delivered to each spray pipe 22 through the water supply pipe 212, and then sprayed out through the nozzle 23 to clean the workpiece. In this embodiment, the water supply pipe 212 can be fixed on any one of the mounting brackets 21 according to the actual situation.

[0032] Furthermore, a drive frame 3 is fixedly installed on the rear side of each spray assembly 2. Specifically, the drive frame 3 is fixed on multiple spray pipes 22. An elliptical opening 31 is opened in the middle of the drive frame 3. An eccentric cam 32 is installed in the opening 31 of the drive frame 3. A first rotating shaft 33 for driving its rotation is installed on the eccentric cam 32.

[0033] As attached Figure 5-6 As shown, the drive device 4 is located below the spray box 1. In this embodiment, the drive device 4 is a motor. A main drive shaft 41 is fixedly installed on the output shaft of the drive device 4. The output shaft of the drive device 4 and the main drive shaft 41 are connected by a coupling 6. The coupling 6 can effectively transmit torque and ensure the stability of power transmission. The main drive shaft 41 is provided with multiple mounting seats 411 that rotate with it. The main drive shaft 41 is installed on the ground through multiple mounting seats 411. The mounting seats 411 provide stable support for the main drive shaft 41 and ensure that it will not deviate during rotation.

[0034] Multiple transmission components 5 are positioned corresponding to multiple sets of spray components 2. The two ends of the transmission components 5 are respectively connected to the main drive shaft 41 and the corresponding first rotating shaft 33. The drive device 4 drives the first rotating shaft 33 to rotate through the transmission components 5. When the first rotating shaft 33 rotates, it drives the spray components 2 to move up and down within the spray area 11.

[0035] Specifically, the transmission assembly 5 includes a drive gear 51, a driven gear 52, and a transmission chain 53. The drive gear 51 is interference-fixed on the main drive shaft 41, and the driven gear 52 is interference-fixed on the corresponding first rotating shaft 33. The drive gear 51 and the driven gear 52 are connected by the transmission chain 53.

[0036] During operation, the drive unit 4 starts, and its output shaft drives the main drive shaft 41 to rotate through the coupling 6. When the main drive shaft 41 rotates, the drive gear 51 fixed on it rotates accordingly. The drive gear 51 drives the driven gear 52 to rotate through the transmission chain 53, which in turn causes the first rotating shaft 33, which is interference-fitted with the driven gear 52, to rotate. When the first rotating shaft 33 rotates, it drives the eccentric cam 32 to rotate. Since the eccentric cam 32 is set in the elliptical opening 31 of the drive frame 3, the rotation of the eccentric cam 32 will push the drive frame 3 to move up and down, thereby driving the spray assembly 2 to move up and down on the slide rail 12 of the spray box 1 through the slider 211. During the movement of the spray assembly 2, the water supply pipe 212 continuously supplies water to the spray pipe 22. The water flows through the nozzle 23 and sprays onto the workpiece located in the spray area 11, realizing the comprehensive cleaning of the workpiece.

[0037] In summary, this invention changes the traditional fixed spray pipe 22-channel mode. Through the cooperation of the drive device 4, transmission component 5, eccentric cam 32 and drive frame 3, the spray component 2 is driven to move up and down within the spray area 11, so that the spray range of the nozzle 23 is no longer limited to a fixed position, and can cover a larger workpiece surface area, effectively reducing the number of cleaning dead corners. Since the spray component 2 can move up and down, the nozzle 23 can spray the workpiece from different heights during the movement. For products with complex shapes or positional deviations, it can clean each part more evenly, avoiding insufficient cleaning in some areas, thereby ensuring product quality.

[0038] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model; all technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of protection of this utility model.
