[0038] In the prior art, an overflow device is used to filter and purify the liquid medicine in the liquid medicine tank. However, the overflow device is a finished product, and the overflow height cannot be adjusted during use, resulting in low versatility and inconvenient cleaning of the glue slag. In addition, the existing overflow device has a slow overflow speed, resulting in a long time-consuming overflow step and low efficiency.
[0039] To solve the above problems, this embodiment provides an overflow device. Refer to Figures 1-4 , which includes a partition 10, a primary overflow member 20, and a secondary overflow member 30. The partition 10 is disposed inside the liquid medicine tank 100 and is hermetically connected to the bottom of the liquid medicine tank 100. A liquid passing hole 11 is provided on the partition 10. The primary overflow member 20 is detachably disposed on one side of the partition 10 and communicates with the liquid passing hole 11. The primary overflow member 20 and the partition 10 together form a first overflow port and a slag storage end. The first overflow port is located above the primary overflow member 20, and the slag storage end is located below the primary overflow member 20. The secondary overflow member 30 is detachably disposed on the other side of the partition 10 and communicates with the liquid passing hole 11. The secondary overflow member 30 and the partition 10 together form a second overflow port. The second overflow port is located above the secondary overflow member 30, and the height of the secondary overflow member 30 is adjustable. The horizontal height of the first overflow port is higher than the horizontal height of the second overflow port. The liquid medicine can sequentially pass through the first overflow port, the liquid passing hole 11, and the second overflow port and flow out, and the glue slag can precipitate at the slag storage end. By adjusting the height of the secondary overflow member, the versatility of the overflow device is increased; the detachable primary overflow member and secondary overflow member facilitate the cleaning of the glue slag and improve the convenience of the overflow device.
[0040] Specifically, both the primary overflow member 20 and the secondary overflow member 30 are provided as arc-shaped plates, and both the first overflow port and the second overflow port are provided as U-shaped to increase the overflow port and thereby increase the overflow flow rate and improve the overflow efficiency.
[0041] Exemplarily, during use, the liquid medicine is first stored outside the primary overflow member 20. When the liquid level of the liquid medicine gradually increases to be flush with the height of the first overflow port, the liquid medicine flows into the liquid storage cavity between the primary overflow member 20 and the secondary overflow member 30 for storage and precipitation of the glue slag. When the liquid medicine in the liquid storage cavity is flush with the height of the second overflow port, the liquid medicine flows to the outside of the secondary overflow member 30, and at the same time, the glue slag is stored at the slag storage end (the bottom of the liquid storage cavity).
[0042] Further, first through holes are provided on both sides of the liquid passing hole 11 in the horizontal direction, first fixing plates 31 are provided on both sides of the secondary overflow member 30 in the horizontal direction, and a plurality of second through holes 311 are provided on the first fixing plates 31 in the vertical direction. The fixing member 40 can pass through any one of the second through holes 311 and then penetrate into the first through hole to adjust the height of the secondary overflow member 30. Specifically, the fixing member 40 is set as a plastic bolt, and the plastic material can avoid chemical reactions with the liquid medicine. Second fixing plates 21 are provided on both sides of the primary overflow member 20 in the horizontal direction, and threaded holes 211 are provided on the second fixing plates 21. The plastic bolt passes through any one of the second through holes 311 and the first through hole in sequence and is screwed with the threaded hole 211 to fix the primary overflow member 20 and the secondary overflow member 30 to the partition plate 10.
[0043] In other embodiments, a ratchet can also be provided on the first fixing plate 31 and a ratchet bar can be provided on the partition plate 10 to adjust the height of the secondary overflow member 30; or the connection manner between the partition plate 10 and the first fixing plate 31 can be set as a sleeve and slide bar type, and the telescopic marble method is used to adjust the height of the secondary overflow member 30.
[0044] Further, the second through holes 311 in the same vertical column are taken as a group, and two groups of the second through holes 311 are arranged at intervals in the horizontal direction. This increases the adjustability of the width of the secondary overflow member 30 in the horizontal direction and improves the versatility of the overflow device.
[0045] Further, two adjacent second through holes 311 in the same group intersect. Cloud-shaped holes are formed between the plurality of second through holes 311, which will neither affect the fixation of the plastic bolt nor increase the distance between the plurality of second through holes 311, thus saving the material cost of the first fixing plate 31.
[0046] Further, digital scales are provided on the peripheries of all the second through holes 311 to mark the liquid level height of the second overflow port when the fixing member 40 passes through the second through hole 311. This realizes the precise adjustment of the secondary overflow member 30.
[0047] Further, a handle member is provided at one end of the plastic bolt. This facilitates the manual screwing of the plastic bolt and increases the convenience of disassembling the primary overflow member 20 and the secondary overflow member 30.
[0048] Further, since the liquid level difference on both sides of the primary overflow member 20 is relatively large, in order to prevent the primary overflow member 20 from being pressed too hard and falling off the partition plate 10, a reinforcing plate 22 is provided between the second fixing plate 21 and the primary overflow member 20 to increase the stability of the primary overflow member 20.
[0049] Further, a sealing plate 32 is provided at one end of the secondary overflow member 30 away from the second overflow port. The sealing plate 32 can be in close contact with the partition plate 10 to prevent the liquid medicine from flowing out from below the secondary overflow member 30. Further, a silica gel strip or a silica gel pad can be provided between the sealing plate 32 and the partition plate 10 to increase the sealing performance of the sealing plate 32.
[0050] This embodiment also provides a multi-stage overflow system. Refer to Figure 5 , including the above-mentioned overflow device, and a plurality of overflow devices are arranged at intervals along the liquid medicine flow direction.
[0051] Specifically, the medicine tank 100 is divided into a plurality of soaking areas by a plurality of partition plates 10. Here, taking the first-stage soaking area to the sixth-stage soaking area as an example, the circuit board is cleaned from the first-stage soaking area to the sixth-stage soaking area in sequence. Since the glue residues on the circuit board gradually decrease, the liquid medicine from the first-stage soaking area to the sixth-stage soaking area also changes from turbid to clean. In order to prevent the excessive impurities in the liquid medicine in the front soaking area from affecting the soaking effect, in this embodiment, the liquid inlet pipe is connected to the sixth-stage soaking area, and the liquid discharge pipe is connected to the first-stage soaking area. The clean liquid medicine enters the sixth-stage soaking area through the liquid inlet pipe, so that the clean liquid medicine in the sixth-stage soaking area overflows towards the first-stage soaking area, and the liquid discharge pipe discharges the liquid medicine with more impurities in the first-stage soaking area. In this way, the circulation flow is carried out to ensure that the liquid medicine in each soaking area is clean enough and ensure the soaking effect of the circuit board.
[0052] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
