[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] To solve the problem in the prior art that it is difficult to ensure that there are no attachments on the parts within the replacement cycle, the embodiment of the present utility model provides an oil film treatment device for the solution tank 1, Figure 1 It is a three-dimensional structural schematic diagram of the oil film treatment device for the solution tank provided by the embodiment of the present utility model, as Figure 1 shown. The device includes: a seesaw 2, which is fixed to the top of the solution tank 1 through a vertical shaft 8 and is provided with an opening corresponding to the mouth of the solution tank 1; slide rails 3, slide rails 3 are respectively provided on the two long sides of the seesaw 2, and each slide rail 3 is provided with a slider 4; a scraper 5, both ends of the scraper 5 are respectively connected to the two sliders 4, and the bottom passes through the opening of the seesaw 2 and contacts the solution surface; supports 6, supports 6 are respectively provided on the two short sides of the seesaw 2; a sliding beam 7, both ends of the sliding beam 7 are respectively connected to the two supports 6, and a sliding hammer 10 that can slide along the sliding beam 7 is provided on the sliding beam 7.

[0023] As Figure 1 , Figure 2 shown, the oil film treatment device for the solution tank needs to be installed above each solution tank of the electroplating production line. Specifically, the seesaw 2 is a frame structure, that is, a rectangular structure with an opening in the middle, and its opening is adapted to the top opening of the solution tank 1, which can ensure that the parts can enter and can ensure that the scraper 5 can move from one side of the solution tank 1 to the other side without obstruction. The seesaw 2 is fixed to the upper part of the solution tank 1 through a vertical shaft 8, and the seesaw 2 and the vertical shaft 8 are connected by an axis, so the left and right sides of the seesaw 2 can tilt up and down.

[0024] On each long side of the seesaw 2, a slide rail 3 is installed. The direction of the slide rail 3 is the same as the long side direction of the seesaw 2, and each slide rail 3 is provided with a slider 4. The slider 4 can reciprocate along the slide rail 3. The two sliders 4 are respectively connected to both ends of the scraper 5. The bottom of the scraper 5 can pass through the opening of the seesaw 2 and enter the solution tank 1, and the bottom surface of the scraper 5 should at least touch the solution surface in the solution tank 1. Thus, when the left side of the seesaw 2 tilts upward, the scraper 5 can slide from the left side to the right side of the seesaw 2; when the right side of the seesaw 2 tilts upward, the scraper 5 can slide back from the right side to the left side of the seesaw 2. Then, during this process, the scraper 5 can scrape the impurities or oil film floating on the surface layer of the solution in the solution tank 1 to the other side, and this can be repeated.

[0025] Furthermore, in order to facilitate the control of the movement of the scraper 5, a sliding beam 7 is longitudinally arranged on the seesaw 2. Both ends of the sliding beam 7 are fixed by brackets 6 arranged on the short sides of the seesaw 2. A sliding weight 10 is sleeved on the sliding beam 7. The sliding weight 10 can slide along the sliding beam 7. The position where the sliding weight 10 is located is the position where gravity is generated, that is, the seesaw 2 will tilt towards the side where the sliding weight 10 is located, thereby driving the scraper 5 to slide towards the tilted side, and at the same time scraping the impurities or oil film on the solution surface from one side to the other side. At this time, there are no impurities and oil film on the solution surface of the solution tank 1. Control the parts to be processed in this state. When the parts are processed or about to be processed, then move the sliding weight 10 to the other side, and use the scraper 5 to process the solution surface layer again. When the scraper 5 moves to the other side, the parts after surface treatment can be taken out. During this process, the phenomenon of secondary contamination of the parts by impurities or oil film is reduced or avoided during the two main processes of immersing the parts in the solution and taking out the solution. Therefore, the appearance quality and coating quality of the parts after surface treatment are greatly improved.

[0026] As an alternative implementation, the device further includes a hanging rod 9. The hanging rod 9 is connected to the bottom of the seesaw 2 and is used for hanging the workpiece to be processed.

[0027] As Figure 1 、 Figure 2 shown, the device further includes a hanging rod 9. The hanging rod 9 is arranged at the bottom of the seesaw 2 and is fixedly connected to the bottom surface of the seesaw 2. When processing parts, the parts can be hung on the hanging rod 9, which is convenient for batch processing.

[0028] As an alternative implementation, the hanging rod 9 includes an integrally formed connecting portion and a hanging portion; both ends of the hanging portion are respectively provided with a connecting portion. The end of the hanging portion extends obliquely upward and is connected to the corresponding connecting portion. The connecting portion is connected to the bottom of the seesaw 2, and the hanging portion is used for hanging the workpiece to be processed.

The two connecting portions are respectively connected to the bottom surfaces of the two short sides of the rocker plate 2, and a hanging portion is provided between the two connecting portions. The two ends of the hanging portion extend obliquely and are connected to the connecting portions respectively, and the hanging portion can be closer to the solution in the solution tank 1.

[0030] As an alternative embodiment, there are two vertical shafts 8, and each vertical shaft 8 is provided at the middle of the long side of the solution tank 1 where it is located.

[0031] At the middle of each long side of the solution tank 1, a vertical shaft 8 is provided. The rocker plate 2 is connected to the solution tank 1 through the vertical shafts 8 on both sides of the long side, and the axis of the vertical shaft 8 is connected to the centers on both sides of the rocker plate 2 to ensure uniform force on both sides of the rocker plate 2.

[0032] As an alternative embodiment, the vertical shaft 8 is of an L-shaped structure, one folded edge of which is fixed on the solution tank 1, and the other folded edge is movably connected to the side edge of the rocker plate 2 through a pin shaft.

[0033] As Figure 1 As shown, the vertical shaft 8 is of an L-shaped structure, including two mutually perpendicular folded edges. One of the folded edges is fixed on the long side of the solution tank 1, and preferably, the vertical shaft 8 is fixed by means of screws. The other folded edge is movably connected to the long side of the rocker plate 2 through a pin shaft.

[0034] As an alternative embodiment, the direction of the sliding beam 7 is the same as the longitudinal central axis of the rocker plate 2, and it is provided above the longitudinal central axis of the rocker plate 2.

[0035] The sliding beam 7 is provided above the longitudinal central axis of the rocker plate 2, and the direction of the sliding beam 7 is the same as the direction of the longitudinal central axis of the rocker plate 2, ensuring uniform force on the rocker plate 2 and not affecting the normal movement of the rocker plate 2.

[0036] As an alternative embodiment, the sliding hammer 10 is cylindrical, and the sliding beam 7 passes through the axis of the sliding hammer 10.

[0037] As Figure 1 As shown, the sliding hammer 10 is cylindrical, the axis of the sliding hammer 10 passes through the sliding beam 7, and by moving the sliding hammer 10, the position of the sliding hammer 10 on the sliding beam 7 is changed, thereby changing the position generated by the gravity of the rocker plate 2, and the rocker plate 2 also tilts with the sliding hammer 10. Since the axis of the sliding hammer 10 coincides with the sliding beam 7, uniform force is ensured and the rocker plate 2 is not affected.

[0038] As an alternative embodiment, the scraper 5 includes a cross beam and a connecting plate; the two ends of the cross beam are respectively connected to the corresponding sliders 4; the connecting plate is provided at the bottom of the cross beam.

The two ends of the cross beam are respectively connected to the top surfaces of the two sliders 4, and the connecting plate is connected to the bottom surface of the cross beam. The material of the connecting plate should be a metal material or a wooden board that will not be affected by the solution.

[0040] As an alternative embodiment, an installation groove is provided at the bottom of the cross beam; one side of the connecting plate is detachably connected in the installation groove.

[0041] An installation groove is provided at the bottom of the cross beam, and one side of the connecting plate is connected to the cross beam through the installation groove. In this way, it can be ensured that the connecting plate can be easily disassembled and assembled from the cross beam, so as to clean the surface of the connecting plate and ensure that the squeegee has a high scraping quality each time it scrapes the surface layer of the solution. In addition, connecting plates of different sizes can be prepared and corresponding-sized connecting plates can be replaced when the depth of the solution is different.

[0042] As an alternative embodiment, an opening corresponding to the hanging rod 9 is provided in the middle of the connecting plate.

[0043] As Figure 1 shown, an opening is provided in the middle of the squeegee 5. The position of the opening is the same as that of the hanging rod 9, and the size of the opening is slightly larger than the diameter of the hanging rod 9.
