Description

Technical Field

[0001] This application relates to the technical field of PCB board processing equipment, and in particular to a manual rotary cleaning device for a chemical tank. Background Technology

[0002] In PCB manufacturing, various chemicals are used to treat the board surface, forming circuitry or copper pillars. These chemicals crystallize and easily accumulate dust and dirt. This dust and dirt not only affects the heat dissipation of the equipment but can also corrode it. Therefore, regular cleaning of the equipment is necessary. However, chemicals can splash onto the inner wall of the machine and areas that cannot be sprayed, resulting in incomplete cleaning. This can cause the concentration of new chemicals to differ from the set value, leading to unintended damage to the circuitry or copper pillars formed on the product surface. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides a manual rotary cleaning device for chemical tanks, which has the advantage of ensuring comprehensive cleaning coverage and thus guaranteeing cleaning effectiveness.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A manual rotary cleaning device for a chemical tank includes a plurality of cleaning pipes disposed in the chemical tank and a rotary drive for driving at least one of the cleaning pipes to rotate, wherein a plurality of nozzles are disposed on the cleaning pipes.

[0006] The rotation drive includes an adjustment shaft rotatably mounted on the chemical tank, a worm gear mounted on the adjustment shaft, a worm wheel that engages with the worm gear transmission on the cleaning pipe, and an adjustment wheel mounted on the adjustment shaft.

[0007] The above technical solution is achieved by having the adjusting wheel drive the adjusting shaft to rotate, which in turn causes the worm gear on it to rotate, which in turn drives the worm wheel to rotate, thereby driving the cleaning pipe to rotate. This causes the nozzles on the cleaning pipe to rotate and rinse the periphery of the chemical tank, thus ensuring comprehensive cleaning coverage and thus ensuring the cleaning effect.

[0008] As a preferred embodiment of this application, four cleaning pipes are arranged around the chemical tank, and a transfer water box for interconnection is provided between the cleaning pipes.

[0009] To achieve the above technical solution, only one water inlet is needed for liquid supply, reducing pipeline design and complexity. Four cleaning pipes are set along the four sides of the cleaning tank, thereby ensuring that the cleaning pipes can spray and rinse evenly around the cleaning tank to ensure the cleanliness of the rinsing.

[0010] As a preferred embodiment of this application, the main shaft is transversely inserted into the chemical tank, and two worm gears are provided on the adjusting shaft, with two worm wheels corresponding to each other, and the two worm gears are respectively installed in two cleaning pipes.

[0011] The above technical solution enables the adjustment shaft to drive both cleaning pipes to rotate simultaneously, thus ensuring thorough cleaning. The two worm gears are respectively set to left and right teeth, so that the adjustment shaft can drive the two cleaning pipes to rotate in opposite directions. As a result, when the adjustment wheel rotates, the two cleaning pipes rotate to flush the chemical tank, thus ensuring the cleanliness of the flushing.

[0012] As a preferred embodiment of this application, the cleaning pipe is provided with a wear-resistant bushing, and the wear-resistant bushing is provided with a fixing seat for mounting on the cleaning tank.

[0013] To achieve the above technical solution, the fixing seat is fixed to the side wall of the chemical tank, thereby supporting and fixing the rinsing pipe and ensuring the stability of the worm gear and transmission.

[0014] As a preferred embodiment of this application, a leak-proof V-RING is provided between the cleaning pipe and the connecting water box.

[0015] The above technical solution is implemented for sealing purposes, thereby reducing the occurrence of leaks.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] The adjusting wheel drives the adjusting shaft to rotate, which in turn causes the worm gear on it to rotate, which in turn drives the worm wheel to rotate, thereby driving the cleaning pipe to rotate. This causes the nozzles on the cleaning pipe to rotate and rinse the periphery of the chemical tank, thus ensuring comprehensive cleaning coverage and achieving the desired cleaning effect.

[0023] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0024] This application discloses a manual rotary cleaning device for chemical tanks. (Refer to...) Figure 1 A manual rotary cleaning device for a chemical tank 1 includes several cleaning pipes 2 disposed in the chemical tank 1 and a rotary drive 3 for driving at least one of the cleaning pipes 2 to rotate. Several nozzles 21 are disposed on each cleaning pipe 2. In this embodiment, four cleaning pipes 2 are disposed along the perimeter of the cleaning tank, ensuring that the cleaning pipes 2 can spray and rinse evenly around the perimeter of the cleaning tank, thus guaranteeing the cleanliness of the rinsing. A connecting water box 4 is provided between the four rinsing pipes for interconnection, thereby achieving liquid supply through a single inlet, reducing pipeline design and complexity.

[0025] The rotating drive component 3 includes an adjusting shaft 31 rotatably mounted on the chemical tank 1, a worm gear 32 mounted on the adjusting shaft, a worm wheel 33 on the cleaning pipe 2 that drives the worm gear 32, and an adjusting wheel 34 mounted on the adjusting shaft 31. That is, the adjusting wheel 34 drives the adjusting shaft 31 to rotate, which in turn causes the worm gear 32 to rotate, which in turn drives the worm wheel 33 to rotate, thereby driving the cleaning pipe 2 to rotate. This causes the nozzles 21 on the cleaning pipe 2 to rotate and rinse the periphery of the chemical tank 1, ensuring comprehensive cleaning coverage and thus guaranteeing the cleaning effect.

[0026] In this embodiment, the adjusting shaft 31 is transversely inserted into the chemical tank 1. Two worm gears 32 are provided on the worm 32, and two worm wheels 33 are provided, each corresponding to one of the worm wheels 33. The two worm gears 32 are respectively mounted on the two cleaning pipes 2, so that when the adjusting shaft 31 rotates, it can simultaneously drive the two cleaning pipes 2 to rotate, thus ensuring thorough cleaning. The two worm gears 32 are respectively configured with left and right teeth, so that when the adjusting shaft 31 rotates, it can drive the two cleaning pipes 2 to rotate in opposite directions. Therefore, when the adjusting wheel 34 rotates, the two cleaning pipes 2 rotate to flush the chemical tank 1, thus ensuring the cleanliness of the flushing.

[0027] To ensure the smooth rotation of the cleaning pipe 2, a wear-resistant bushing 35 is provided on the cleaning pipe 2, and a fixing seat 36 is provided on the wear-resistant bushing 35. The fixing seat 36 is fixed on the side wall of the chemical tank 1, thereby supporting and fixing the cleaning pipe and ensuring the stability of the worm gear 32 and worm wheel 33 in terms of force and transmission.

[0028] To prevent leakage when the cleaning pipe 2 rotates, a leak-proof V-RING 5 is installed between the cleaning pipe 2 and the connecting water box 4 for sealing and to reduce the occurrence of leakage.

[0029] The implementation principle of the manual rotary cleaning device for a chemical tank in this application embodiment is as follows: the adjusting wheel 34 drives the adjusting shaft 31 to rotate, which in turn causes the worm gear 32 on it to rotate, which in turn drives the worm wheel 33 to rotate, thereby driving the cleaning pipe 2 to rotate, which in turn causes the nozzle 21 on the cleaning pipe 2 to rotate and rinse the periphery of the chemical tank 1, thereby ensuring the comprehensiveness of the cleaning direction and thus ensuring the cleaning effect.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
