It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0019] As Figures 1 to 6As shown in the figure, the present utility model provides a circuit board cleaning device 100 with an automatic compensation control function, which includes a cleaning table 10, a mounting frame 20, a material grabbing assembly 30, a detection assembly 40, a cleaning liquid supply assembly 50 and an analysis control system (not shown in the figure). A plurality of cleaning tanks 11 with open upper ends are provided on the cleaning table 10. The mounting frame 20 stands on the cleaning table 10. The material grabbing assembly 30 is installed on the mounting frame 20. The detection assembly 40 is installed on the cleaning table 10 and the mounting frame 20. The cleaning liquid supply assembly 50 is installed on the processing table and communicated with each cleaning tank 11. The analysis control system is respectively in signal connection with the material grabbing assembly 30, the detection assembly 40 and the cleaning liquid supply assembly 50. It can be understood that in the present utility model, there are also several power supply structures, air supply structures, driving devices, suction and pumping devices and displacement positioning sensors. Since they are all conventional technical contents in this technical field, they will not be described in detail here.

[0020] The mounting frame 20 includes two groups of vertical frames 21 and a transverse sliding frame 22. The two groups of vertical frames 21 are respectively located on both sides of the cleaning table 10. The two groups of transverse sliding frames 22 are respectively installed transversely in the middle of the two groups of vertical frames 21, and a feeding slide rail 221 is also provided inside the transverse sliding frame 22. The material grabbing assembly 30 is snap-fitted on the feeding slide rail 221 and can slide left and right. The alignment grabbing camera 42 is installed on one of the vertical frames 21. The mounting structure with the vertical frame 21 and the transverse sliding frame 22 can not only realize the sliding feeding function of the material grabbing assembly 30, but also will not interfere with the image grabbing and detection operation of the detection assembly 40.

[0021] The material grabbing assembly 30 includes two groups of material grabbing robotic arms 31 symmetrically arranged front and back. The material grabbing robotic arm 31 includes a transverse telescopic rod 311, a longitudinal telescopic rod 312 and a rotating gripper 313. One end of the transverse telescopic rod 311 is snap-fitted on the feeding slide rail 221 and can slide left and right. One side of the longitudinal telescopic rod 312 is fixedly installed at the other end of the transverse telescopic rod 311 and can move back and forth driven by the transverse telescopic rod 311. The rotating gripper 313 is pivotally connected to the lower end of the longitudinal telescopic rod 312 and can move up and down driven by the longitudinal telescopic rod 312. The rotating gripper 313 can also rotate actively.

[0022] The two groups of material grabbing robotic arms 31 arranged symmetrically can grab both sides of the circuit board, and the circuit board can be loaded and unloaded by synchronously sliding along the feeding slide rail 221. The material grabbing robotic arm 31 that can move horizontally can adjust the distance between each other, so as to realize the grabbing and feeding of circuit boards with different widths. The rotating gripper 313 that can rotate actively can drive the circuit board to flip, so that the circuit board can be double-sided detected.

[0023] The detection component 40 includes a detection table 41 and a positioning and grasping camera 42. The detection table 41 is installed on one side of the cleaning table 10, and the positioning and grasping camera 42 is installed on the mounting frame 20 and is located above the detection table 41. The positioning and grasping camera 42 is also signal-connected to the analysis and control system. The detection table 41 can carry the circuit board, and the positioning and grasping camera 42 above can capture the image on the surface of the circuit board. Then the image will be uploaded to the analysis and control system for analysis and processing, so as to obtain the detection result of the pollution degree of the circuit board. Finally, the analysis system will control the material grasping component 30 to re-grasp the circuit board and put it into the corresponding cleaning tank 11 for cleaning according to the detection result.

The movable lifting block 412 is engaged in the lifting through-hole 411a and can move up and down. The lifting cylinder 413 is fixedly installed in the cleaning table 10 and its upper end is in abutting connection with the movable lifting block 412. A plurality of negative pressure suction holes 411b are also provided on the fixed tabletop 411. After the circuit board is placed on the detection table 41 for detection, the lifting cylinder 413 can drive the movable lifting block 412 to lift, and further drive the circuit board to rise and separate from the fixed tabletop 411, which is more convenient for the material grasping robotic arm 31 to clamp the side of the circuit board. The negative pressure suction holes 411b on the fixed tabletop 411 can firmly adsorb the circuit board, keep the circuit board flat and not deviate during the detection process, and prevent affecting the detection result.

[0025] The cleaning liquid supply component 50 includes a cleaning liquid supply tank 51, a clean water supply tank 52, a plurality of pipes (not shown in the figure) and solenoid valves (not shown in the figure).

Among them, the cleaning liquid supply tank 51 is connected to a plurality of cleaning tanks 11 via a plurality of pipes respectively, and the clean water supply tank 52 is also connected to a plurality of cleaning tanks 11 via a plurality of pipes respectively. A plurality of the solenoid valves are respectively installed on the plurality of pipes and are signal-connected to the analysis and control system respectively. The solenoid valves on the liquid supply pipes can accurately adjust the flow rate under the control of the analysis and control system, so as to realize the adjustment of the cleaning liquid concentration in the cleaning tank 11.

[0026] Specifically, in this embodiment, concentration detection sensors (not shown in the figure), temperature detection sensors (not shown in the figure), and heaters (not shown in the figure) are provided in each of the plurality of cleaning tanks 11. The plurality of concentration detection sensors, temperature detection sensors, and heaters are all signal-connected to the analysis and control system.

Then, the analysis and control system can adjust the concentration and temperature of the cleaning liquid according to the cleaning requirements to achieve the best matching cleaning with the circuit board to be cleaned.

[0027] In summary, the beneficial effects of the circuit board cleaning device 100 with an automatic compensation control function of the present invention are as follows: By designing the detection component 40 to cooperate with the analysis and control system to detect the degree or type of pollution of the circuit board to be cleaned, and then controlling the material grabbing component 30 to send the circuit board into the corresponding cleaning tank 11 for cleaning and processing according to the detection result, not only can each circuit board be cleaned more thoroughly, but also the utilization of the cleaning liquid is more sufficient; The cleaning liquid supply component 50 is designed with multiple solenoid valves to cooperate with the concentration detection sensors in the cleaning tank 11 to accurately control the concentration level of the cleaning liquid in the plurality of cleaning tanks 11, ensuring that circuit boards with different pollution degrees can be cleaned in cleaning liquids with different concentration ranges. The temperature detection sensors in the cleaning tank 11 cooperate with the heaters to accurately control the temperature of the cleaning liquid, so that the cleaning effect of the cleaning liquid is optimized. The present invention has strong practicability and has strong promotion significance.
