[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0029] Embodiment 1

[0030] Reference Figure 1-Figure 6 As shown, the utility model discloses a device for reducing leakage of soaking liquid, comprising:

[0031] A support assembly 1, the support assembly 1 comprises a first support frame 11 and a second support frame 12 arranged opposite to each other, a first shaft sleeve 13 is clamped in the second support frame 12, and a first shaft sleeve 13 is provided with a first shaft hole 131 and a U-shaped groove 132;

[0032] The rolling assembly 2 includes a plurality of first rotating shafts 21 and a plurality of second rotating shafts 22, wherein the axial direction of the first rotating shaft 21 is arranged parallel to the axial direction of the second rotating shaft 22, and the second rotating shaft 22 is arranged on the top of the first rotating shaft 21; one end of the first rotating shaft 21 and the second rotating shaft 22 is penetrated in the first supporting frame 11, the first rotating shaft 21 is penetrated in the first shaft hole 131, and the end of the second rotating shaft 22 is penetrated in the U-shaped groove 132;

[0033] The water blocking ring 3 is sleeved on one end of the second rotating shaft 22 close to the second supporting frame 12 , and the outer diameter of the water blocking ring 3 is greater than the width of the U-shaped groove 132 .

[0034] It can be seen that the structure of the support assembly 1 in the utility model is composed of a first support frame 11 and a second support frame 12, and a plurality of first rotating shafts 21 and second rotating shafts 22 are arranged between the first support frame 11 and the second support frame 12, and the product passes between the first rotating shafts 21 and the second rotating shafts 22. The first rotating shafts 21 and the second rotating shafts 22 are directly inserted into the first support frame 11, and the first sleeve 13 arranged on the second support frame 12 is used to install the other ends of the first rotating shafts 21 and the second rotating shafts 22, wherein the first rotating shaft 21 is inserted into the first shaft hole 131 at the bottom of the first sleeve 13, and the end of the second rotating shaft 22 is inserted into the U-shaped groove 132 at the top, and the second rotating shaft 22 at the top is made into an open shape, which is convenient for disassembly on the one hand and convenient for the passage of the product on the other hand.

[0035] The water blocking ring 3 is sleeved on one end of the second rotating shaft 22 close to the second support frame 12, and the water blocking ring 3 is arranged closely against the second support frame 12. Specifically, since the water blocking ring 3 is sleeved on the inner side of the second support frame 12, the outer diameter of the water blocking ring 3 is larger than the width of the U-shaped groove 132, and a seal is formed on the U-shaped groove 132. During use, the immersion liquid 5 can be prevented from leaking from the U-shaped groove 132, thereby ensuring the liquid level height of the immersion tank 4 and effectively improving the product yield.

[0036] Furthermore, a second shaft sleeve 14 is disposed on the first support frame 11 , and a second shaft sleeve 14 is disposed on the second shaft sleeve 14 to match the first rotating shaft, and an inner diameter of the second shaft hole 141 is equal to a diameter of the first rotating shaft 21 .

[0037] Specifically, the first rotating shaft 21 is disposed at the bottom of the second rotating shaft 22 and plays a supporting role during use. The first rotating shaft 21 will not be radially displaced, so both ends of the first rotating shaft 21 are inserted into the first shaft hole 131 and the second shaft hole 141 .

[0038] Furthermore, a blind hole 142 matching with the second rotating shaft 22 is disposed on the second shaft sleeve 14 , and an inner diameter of the blind hole 142 is larger than a diameter of the second rotating shaft 22 .

[0039] Specifically, the end of the second rotating shaft 22 close to the second support frame 12 is openly installed through the U-shaped groove 132. When a product passes through, the height of the entire second rotating shaft 22 will be raised. Therefore, the diameter of the second rotating shaft 22 and the matching blind hole 142 in the second sleeve 14 is larger than the diameter of the second rotating shaft 22, so that the two ends of the second rotating shaft 22 can be adjusted synchronously. It should be noted that since the second rotating shaft 22 will be adjusted when the product passes through, the setting of the blind hole 142 can form a seal for the soaking liquid 5 in the soaking tank 4. In the utility model, the first sleeve 13 and the second sleeve 14 are all detachably connected to the second support frame 12 and the first support frame 11, which is convenient for the assembly of the entire equipment and the disassembly for later maintenance.

[0040] Furthermore, the first rotating shaft 21 is provided with a plurality of first rollers 23 along the axial direction, and the second rotating shaft 22 is provided with a plurality of second rollers 24 along the axial direction, and the first rollers 23 and the second rollers 24 are in contact with each other.

[0041] Specifically, the first roller 23 and the second roller 24 are made into multiple sections, and any two adjacent first rollers 23 or any two adjacent second rollers 24 are mutually engaged.

[0042] Furthermore, it also includes a soaking tank 4, which is arranged at the bottom of the first rotating shaft 21 and the second rotating shaft 22. The soaking tank 4 is provided with a soaking liquid 5, and the liquid level of the soaking liquid 5 is higher than the contact point between the first roller 23 and the second roller 24.

[0043] Specifically, the soaking tank 4 is used to store the soaking liquid 5, and the soaking tank 4 is arranged at the bottom of the first rotating shaft 21 and the second rotating shaft 22. In order to ensure that all the products passing through are immersed in the soaking liquid 5, the liquid level of the soaking liquid 5 is at least higher than the height of the joint between the first roller 23 and the second roller 24.

[0044] Furthermore, it also includes a first water jet 6 and a second water jet 7, wherein the first water jet 6 is arranged between any two adjacent first rotating shafts 21, and the water outlet of the first water jet 6 faces the second roller 24; the second water jet 7 is arranged between any two second rotating shafts 22, and the water outlet of the second water jet 7 faces the first roller 23.

[0045] Specifically, the chemical solution in the soaking tank 4 contains multiple components. In order to effectively contact the chemical solution with the circuit board, it is necessary to circulate the chemical solution in the soaking tank 4 through a water jet in the area where the circuit board passes. The first water jet 6 and the second water jet 7 are respectively facing the second roller 24 and the first roller 23 to shield the impact of the soaking liquid 5, reduce the fluctuation of the liquid level in the soaking tank 4, and reduce the generation of bubbles.

[0046] Furthermore, the water outlets of the first water jet 6 and the second water jet 7 are both immersed in the soaking liquid 5 .

[0047] Specifically, the water outlets of the first water jet 6 and the second water jet 7 are immersed in the soaking liquid 5 to prevent the soaking liquid 5 sprayed by the water jets from impacting the soaking liquid 5 in the soaking tank 4 to generate bubbles.
