Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, a PCB finished product cleaning device includes a tin plate cleaning section 1, a gold plate cleaning section 2 and a water inlet pipe, wherein the tin plate cleaning section 1 and the gold plate cleaning section 2 are both a box body and are all provided with cleaning cavities. In order to prevent the gold on the PCB from reacting when the water after tin washing is used for washing and removing the gold again, the tin plate washing section 1 and the gold plate washing section 2 are provided with independent water inlet and independent water outlet, namely the tin plate washing section 1 is provided with a tin washing water inlet 11 and a tin washing water outlet 12, the gold plate washing section 2 is provided with a gold washing water inlet 21 and a gold washing water outlet 22, and the tin washing water outlet 12 is not communicated with the gold washing water inlet 21. The tin washing water inlet 11 and the gold washing water inlet 21 are both used for being connected with a water inlet pipe.

Here, it should be noted that: the inlet and outlet structures of the tin plate cleaning section 1 and the gold plate cleaning section 2 are the same, so the tin plate cleaning section 1 is taken as an example for explanation. In tin plate cleaning section 1, still include first inlet tube 13 and second inlet tube 14, wash the quantity of tin water inlet 11 and be two, and the two sets up on tin plate cleaning section 1 with the interval, wash tin water inlet 111 and second respectively for first tin water inlet 112 and the second. The first tin washing water inlet 111 is communicated with the first water inlet pipe 13, and the second tin washing water inlet 112 is communicated with the second water inlet pipe 14. Both the first inlet conduit 13 and the second inlet conduit 14 are used for supplying cleaning liquid. In this embodiment, the first tin washing inlet 111 can be disposed at the upper part of the tin plate cleaning section 1, and the first tin washing inlet 111 is used for providing the cleaning liquid for a long time. In order to control the amount of the cleaning liquid entering the tin plate cleaning section 1, the electromagnetic valve 3 can be installed at the first water inlet pipe 13, so that the opening and closing of the electromagnetic valve 3 can be controlled through the controller, and the effect of controlling the flow is achieved. The second tin washing water inlet 112 can be arranged at the middle upper part of the tin plate cleaning section 1, and the second tin washing water inlet 112 is used for providing cleaning liquid in a short period, namely when the cleaning liquid in the first water inlet pipe 13 is in the replacement process or the first water pipe is maintained, the cleaning liquid can be provided through the second tin washing water inlet 112, so that the continuous flow of the cleaning liquid in the tin plate cleaning section 1 is ensured. The production efficiency is effectively improved. The tin washing water outlet 12 is arranged on the side wall of the tin plate washing section 1 close to the bottom, so that the washing liquid after washing can flow out conveniently. In this implementation, the water at the tin washing water outlet 12 can be directly discharged, and impurities can be filtered through the filter, and then the filtered clean cleaning liquid is introduced into the first water inlet pipe 13 again for recycling.

When the PCB is cleaned, tap water or pure water may be generally used, and the PCB may be cleaned at a low cost using the tap water, but the cleaned PCB may have some other substances due to impurities contained in the tap water. The cleaning quality of the PCB class can be effectively improved by using the pure water, but the cost of the pure water is higher than that of tap water. Therefore, tap water or pure water is required to be selected and used according to actual requirements in the production process. In order to select which water is used for cleaning conveniently, one end of the second water inlet pipe 14 far away from the second tin washing water inlet 112 can be connected with a tee joint 4 in a threaded manner, the other two outlets of the tee joint 4 are respectively connected with a third water inlet pipe 15 and a fourth water inlet pipe 16 in a threaded manner, the third water inlet pipe 15 is used for introducing a first cleaning solution, and the fourth water inlet pipe 16 is used for introducing a second cleaning solution. The first cleaning liquid and the second cleaning liquid are tap water and pure water respectively. In order to facilitate the control of the introduction of the first cleaning liquid or the second cleaning liquid into the second water inlet pipe 14 or the non-introduction of the cleaning liquid, valves 7 may be disposed on the second water inlet pipe 14, the third water inlet pipe 15 and the fourth water inlet pipe 16. This allows the cleaning liquid used to be controlled by opening or closing the valve 7.

In order to facilitate observation of the PCB cleaning condition, the cleaning solution is prevented from splashing from the top of the tin plate cleaning section 1 in the PCB cleaning process, the top surface of the tin plate cleaning section 1 can be hinged with an observation door body 5 which can be opened and closed relative to the tin plate cleaning section 1, and the observation door body 5 can be made of toughened glass. Correspondingly, the top surface of the gold plate cleaning section 2 is provided with an observation door body 5 which can be opened and closed relative to the gold plate cleaning section 2.

As shown in fig. 1, in order to facilitate transporting the PCB from the tin plate cleaning section 1 to the gold plate cleaning section 2, the PCB finished product cleaning device may further include a transmission mechanism 5, and the transmission mechanism 5 is configured to transport the PCB from the tin plate cleaning section to the gold plate cleaning section. In this embodiment, transport mechanism 5 can be the transmission band, and the transmission band passes tin board cleaning section 1 and gold plate cleaning section 2 in proper order, and the transmission band is used for the transmission to wait to wash the PCB board when rotating, compares in manual transport, and this kind of mode is more convenient, and the effect is better moreover.

The implementation principle of the embodiment is as follows: through wasing section 1 and gold plate washing section 2 with the tin plate and setting up independent feed liquor respectively and independently go out liquid, effectively prevent that the tin-containing cleaning solution from wasing section 2 at the gold plate and wasing the PCB board, effectively prevent that the tin from leading to the quality of PCB board to descend with the gold replacement, in addition, can also change the cleaning solution through tee bend 4 and use running water or pure water, under the quality and the cost of guaranteeing the PCB board, it is more nimble.

Here, it should be noted that: in the case of no conflict, a person skilled in the art may combine the related technical features in the above examples according to actual situations to achieve corresponding technical effects, and details of various combining situations are not described herein.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
