Description

Technical Field

[0001] This utility model relates to the technical field of SMT chip cleaning equipment, and in particular to an automatic cleaning machine. Background Technology

[0002] SMT (Surface Mount Technology) assembly involves multiple steps, including printing, mounting, and soldering.

The limiting unit 9 ensures stability during the patch cleaning process.

[0027] The upper end of the cleaning unit 5 is fixedly connected to the water tank 501 at the upper end of the cleaning box 2. A water pump 502 is installed on one side of the water tank 501. An output pipe 503 is fixedly connected to the output end of the water pump 502. A spray pipe 504 is fixedly connected to the end of the output pipe 503 away from the water pump 502. Multiple nozzles 505 are provided at the lower end of the spray pipe 504. The cleaning unit 5 can clean the patch.

[0028] The recycling unit 4 includes a recycling box 401 fixedly connected to the lower end of the workbench 1. Three filter plates 402 are fixedly connected to the inner wall of the recycling box 401. A recycling pump 403 is fixedly connected to one side of the recycling box 401. A return pipe 404 is fixedly connected to the output end of the recycling pump 403. The recycling unit 4 collects the liquid generated during cleaning.

[0029] The end of the return pipe 404 away from the recovery pump 403 is connected to the water tank 501. The filtered liquid is transported to the water tank 501 through the return pipe 404.

[0030] The pore sizes of the three filter plates 402 are divided into large, medium, and small from top to bottom. The collected liquid is filtered through the three filter plates 402 with different pore sizes.

[0031] The collection tank 3 is located at the lower end of the nozzle 504. A baffle is installed on the inner wall of the collection tank 3. A connecting pipe 301 is provided at the lower end of the collection tank 3. The end of the connecting pipe 301 away from the collection tank 3 is connected to the recovery tank 401.

[0034] Working principle: In use, place the patch to be cleaned above the two pads 905. Turning the handle drives the bidirectional lead screw 903 to rotate, causing the two sleeves 904 to move in opposite directions. The movement of the two sleeves 904 adjusts the distance between the two clamping plates 906, facilitating the clamping of patches of different sizes. After clamping, the drive motor 602 can be started to rotate the threaded rod 7, causing the sliding plate 8 to slide along the axial direction of the guide rod 601, sending the patch into the cleaning chamber 2. The water pump 502 is started to draw the cleaning fluid from the water tank 501 and deliver it to the spray pipe 504 through the output pipe 503. Finally, it is evenly sprayed onto the patch through multiple nozzles 505 to clean the patch. The wastewater generated after cleaning is collected through the collection tank 3 and falls into the recycling tank 401 through the connecting pipe 301. The filter plate 402 in the recycling tank 401 removes impurities from the cleaning fluid. The filtered liquid is drawn out by the recycling pump 403 and delivered to the return water tank 501 through the return pipe 404 to achieve recycling.
