[0034] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0035] Refer to Figures 1 to 4 As shown, an embodiment of the present utility model provides a stripping device 10 for an electroplating fixture, which includes a liquid storage cylinder 100 and a liquid baffle 200; a liquid storage cavity 110 is provided inside the liquid storage cylinder 100, and the liquid storage cylinder 100 is provided with a liquid inlet 120 communicating with the liquid storage cavity 110; the liquid baffle 200 is provided with a water outlet hole 210, and the liquid baffle 200 is arranged in the liquid storage cavity 110 to divide the liquid storage cavity 110 into a slow flow cavity 111 communicating with the liquid inlet 120 and an immersion cavity 112 for soaking the electroplating fixture 20, and the positive projection of the liquid inlet 120 on the liquid baffle 200 and the positive projection of the water outlet hole 210 are at least partially non - overlapping; wherein, the external stripping liquid is input into the liquid storage cavity 110 from the liquid inlet 120, and the stripping liquid is used to react with the electroplating fixture 20.

[0036] When using the stripping device 10 of this embodiment, the stripping liquid input from the liquid inlet 120 can be blocked by the liquid baffle 200 to avoid the problem of splashing when the stripping liquid enters the liquid storage cavity 110. The stripping liquid that contacts the liquid baffle 200 then enters the liquid storage cavity 110 from the water outlet hole 210 to contact the electroplating fixture 20 and perform stripping. Specifically, by setting the liquid baffle 200 such that the positive projections of the liquid inlet 120 and the water outlet hole 210 on it are at least partially non - overlapping, the stripping liquid entering the slow flow cavity 111 from the liquid inlet 120 can be at least partially blocked by the liquid baffle 200 to reduce the flow rate, and the stripping liquid can slowly enter the immersion cavity 112 through the water outlet hole 210 to avoid the stripping liquid splashing out from the liquid storage cavity 110.

[0037] Specifically, in the stripping device 10 of this embodiment, by setting the cooperation between the liquid baffle 200 and the liquid inlet 120 of the liquid storage cylinder 100, the problem of splashing when pumping the stripping liquid into the liquid storage cavity 110 can be avoided, thereby improving the use safety of the stripping device 10. The structure is simple and the use effect is good.

[0038] In one embodiment, the liquid baffle 200 is arranged at an angle with the inner wall of the liquid storage cavity 110, and the liquid baffle 200 at least partially covers the liquid inlet 120.

[0039] In this embodiment, the liquid baffle 200 and the inner wall of the liquid storage chamber 110 enclose to form a temporary storage space in the liquid storage chamber 110. The stripping liquid pumped in from the liquid inlet 120 can first enter this temporary storage space. At this time, since the liquid baffle 200 covers the opening of the liquid inlet 120, the stripping liquid entering from the liquid inlet 120 will first splash onto the surface of the liquid baffle 200 and be located in the temporary storage space until the stripping liquid flows into the liquid storage chamber 110 from the water outlet hole 210, so that the stripping liquid can be stored in the liquid storage chamber 110 and can contact the electroplating fixture 20 in the liquid storage chamber 110 and react with the surface of the electroplating fixture 20 to achieve the stripping function.

[0040] Specifically, the angle between the liquid baffle 200 and the side wall of the liquid storage chamber 110 can be 0° to 90°, preferably 30°, 45°, 60°. In a preferred embodiment, the included angle between the liquid baffle 200 and the inner wall of the liquid storage chamber 110 can be made as small as possible to avoid the temporary storage space formed by the enclosure of the liquid baffle 200 and the inner wall of the liquid storage chamber 110 occupying too much space of the liquid storage chamber 110, so that the overall structure of the stripping device 10 is more compact.

[0041] Refer to Figure 3 As shown, in one embodiment, the angle between the liquid baffle 200 and the inner wall of the liquid storage chamber 110 is 45°, and the opening direction of the liquid inlet 120 is parallel to the horizontal direction. At this time, when the stripping liquid enters the liquid storage chamber 110 from the liquid inlet 120, the liquid baffle 200 can be arranged on the conveying path of the stripping liquid and block the droplets splashed by the stripping liquid entering from the liquid inlet 120 to achieve the anti-splash function of the stripping device 10.

[0042] Furthermore, the stripping device 10 further includes a reflux assembly 300. The reflux assembly 300 is respectively connected to the liquid storage chamber 110 and the liquid inlet 120, and the reflux assembly 300 is used to transport the stripping liquid in the liquid storage chamber 110 from the liquid inlet 120 back into the liquid storage chamber 110.

[0043] In this embodiment, by setting the reflux assembly 300 in cooperation with the liquid storage cylinder 100, the excessive stripping liquid in the liquid storage chamber 110 can be recovered, and the stripping liquid can form a transport cycle between the liquid storage cylinder 100 and the reflux assembly 300. In some embodiments, a liquid addition bottle can also be provided in the reflux assembly 300 to supplement the concentration of the stripping materials in the stripping liquid, or a filter can be provided to circulate and filter the stripping liquid.

[0044] In one embodiment, the reflux assembly 300 includes an overflow box 310, a liquid inlet pipe 320, and a reflux pipe 330. The reflux pipe 330 is respectively connected to the overflow box 310 and the liquid inlet pipe 320. The overflow box 310 is connected to the liquid storage cylinder 100 and is used to receive the stripping liquid output from the liquid storage chamber 110. The liquid inlet pipe 320 is connected to the liquid inlet 120 and is used to transport the stripping liquid towards the liquid storage chamber 110.

[0045] With this setting, the excess stripping liquid in the liquid storage cavity 110 can be transported to the overflow box 310 and temporarily stored therein. At this time, the stripping liquid in the overflow box 310 can respectively flow back to the liquid pump through the return pipe 330, and be pumped by the liquid pump and then flow back through the liquid inlet pipe 320 and back into the liquid storage cavity 110 through the liquid inlet 120, thereby forming the return circulation of the return assembly 300.

[0046] Refer to Figure 4 In the illustrated embodiment, the return assembly 300 can be provided on one side of the liquid storage cylinder 100 in the horizontal direction. At this time, the excess stripping liquid in the liquid storage cylinder 100 can flow to the overflow box 310 through the side surface of the liquid storage cavity 110. The return pipe 330 is provided at the bottom of the overflow box 310 and is used to output the stripping liquid, and finally the stripping liquid is pumped by the liquid pump and re-transported from the liquid inlet 120 to the liquid storage cavity 110 through the liquid inlet pipe 320; thereby, the stripping device 10 can be arranged along the conveying direction of the electroplating fixture 20, and the overall structure of the stripping device 10 is more compact.

[0047] In a preferred embodiment, the number of the return assemblies 300 can also be two groups, and the two groups of return assemblies 300 are respectively provided at both ends of the liquid storage cylinder 100 in the length direction, thereby enabling the stripping liquid to flow back at both ends of the liquid storage cylinder 100, with a compact structure and good use effect.

[0048] Specifically, the liquid storage cylinder 100 is provided with a side baffle 130, the side baffle 130 is provided with a conveying groove 131, the overflow box 310 is provided on the side of the side baffle 130 away from the liquid storage cavity 110, and the conveying groove 131 is respectively communicated with the liquid storage cavity 110 and the overflow box 310. The conveying groove 131 is used to convey the electroplating fixture 20.

[0049] In this embodiment, by providing the side baffle 130 on the liquid storage cylinder 100, the conveying groove 131 of the side baffle 130 can be used to separate the liquid storage cavity 110 and the overflow box 310. When the liquid level height in the liquid storage cavity 110 is higher than the bottom of the conveying groove 131, the stripping liquid can flow from the conveying groove 131 to the overflow box 310. By providing the side baffle 130 with the conveying groove 131 of the corresponding height, the liquid level height in the liquid storage cavity 110 can be adjusted, so that the stripping device 10 can be applicable to electroplating fixtures 20 of different specifications.

[0050] Furthermore, the stripping device 10 further includes a water baffle 400. The water baffle 400 is of a flexible structure and adheres to one side of the side baffle 130, and at least part of the water baffle 400 covers the conveying groove 131.

[0051] With this setting, the set water baffle 400 can block the stripping liquid, and when the electroplating fixture 20 enters the liquid storage cavity 110 and / or the overflow box 310, the water baffle 400 can deform so that the electroplating fixture 20 can smoothly pass through the water baffle 400; specifically, the water baffle 400 is provided with a movable opening to simultaneously achieve the functions of blocking water and passing the electroplating fixture 20. The water baffle 400 can be a rubber water baffle or a silica gel water baffle, and the specific material is determined according to the applicable environment of the stripping device 10, and is not uniquely limited here; it should be noted that when the electroplating fixture 20 passes through the water baffle 400 and deforms the water baffle 400, part of the stripping liquid can pass through the water baffle 400, but this does not affect the water blocking function of the water baffle 400.

[0052] In one embodiment, the stripping device 10 further includes an air extraction assembly 500. The liquid storage cylinder 100 is provided with an air hole 140 communicating with the liquid storage cavity 110. The air extraction assembly 500 is communicated with the air hole 140 and is used for discharging the waste gas in the liquid storage cavity 110 to the outside.

[0053] In this embodiment, by setting the air extraction assembly 500 to cooperate with the liquid storage cylinder 100, the air extraction assembly 500 can extract the harmful gas in the liquid storage cavity 110, so that the subsequent process can treat the harmful gas, avoid polluting the environment and improve the use safety of the stripping device 10 at the same time.

[0054] Specifically, the air extraction assembly 500 includes an air extraction box 510 and an air extraction pipe 520. The air extraction box 510 is connected to the liquid storage cylinder 100 and covers the air hole 140. The air extraction pipe 520 is respectively connected to the air extraction box 510 and an external vacuum source and is used for outputting waste gas.

[0055] By setting the air extraction box 510 to cooperate with the liquid storage cylinder 100, the air extraction box 510 can temporarily store the waste gas, and connect to the vacuum source through the air extraction pipe 520 to extract the waste gas; in some embodiments, a filter element can also be provided inside the air extraction box 510 to preliminarily filter the waste gas.

[0056] In a preferred embodiment, the opening of the air hole 140 is above the top of the liquid baffle 200, or is set as close as possible to the conveying groove 131. Such a setting can achieve the following effects: when the stripping liquid is stored in the liquid storage cavity 110, when the height of the air hole 140 is too low, part of the stripping liquid will enter the air extraction box 510 from the air hole 140. In order to improve the air extraction effect of the air extraction assembly 500, the air hole 140 can be set as high as possible in the liquid storage cavity 110 to improve the air extraction effect of the air extraction assembly 500.

[0057] In one embodiment, the number of the air holes 140 is multiple. The air extraction box 510 is provided with an air extraction cavity 511, and the air extraction cavity 511 is respectively communicated with the multiple air holes 140.

[0058] In this embodiment, a plurality of air holes 140 are arranged at intervals along the length direction of the liquid storage cylinder 100, and the air extraction boxes 510 are respectively disposed over the plurality of air holes 140 so that the air extraction cavities 511 are respectively communicated with the plurality of air holes 140. At this time, by providing one or more air extraction pipes 520 connected to the air extraction boxes 510, simultaneous air extraction of the plurality of air holes 140 can be achieved, thereby improving the air extraction effect of the stripping device 10.
