Technical Field

[0001] The invention relates to the technical field, and in particular to a controllable cleaning device for a PCB board. Background Art

[0002] PCB cleaning is an important part of the electronic manufacturing and maintenance process. Cleaning the PCB with a cleaning device can prevent short circuits and improve the heat dissipation of the PCB. Putting the PCB into a cleaning device filled with a suitable cleaning liquid can effectively remove impurities on the surface and gaps of the PCB through ultrasonic vibration. Technical inspiration for the cleaning device; Research on cleaning devices found the following problems: The cleaning device places multiple PCB boards in a cleaning tank and then removes impurities on the surface of the PCB boards through ultrasonic vibration. Since the PCB boards are stacked on top of each other, the cleaning device needs to perform ultrasonic vibration on the PCB boards for a long time, which makes the cleaning time of the PCB boards uncontrollable. Therefore, incomplete cleaning is likely to occur, and the cleaning device cannot separate and clean the PCB boards during the cleaning process. At present, CN202410858597.7 in the prior art discloses a PCB board hole slag cleaning device, in which the support frame platform described in the invention is horizontally arranged, and two mounting platforms are respectively provided at both ends of the support frame platform, and a horizontally arranged linear drive is provided on the top of each mounting platform, and a movable frame is provided on the movable ends of the two linear drives, and the PCB board lifting component is arranged on the support frame platform and the PCB board lifting component and the support frame platform are slidably matched, and the cleaning movable component is arranged on the movable frame and the cleaning movable component and the movable frame are slidably matched, and two multi-angle cleaning components are provided, and the two multi-angle cleaning components are respectively arranged on the two movable ends of the cleaning movable component, which can realize multi-angle cleaning of waste slag on the PCB board, so that the PCB board is cleaned more cleanly; The present invention can mainly solve the problem that the cleaning time of a cleaning device for a PCB board is uncontrollable. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a controllable cleaning device for a PCB board to solve the problems described in the above background technology.

[0004] The purpose and efficacy of a controllable cleaning device for a PCB board of the present invention are achieved by the following specific technical means: a controllable cleaning device for a PCB board comprises an ultrasonic machine, a cleaning tank is provided on the side of the ultrasonic machine, rollers are rotatably penetrated on both sides of the cleaning tank, and side arms are distributed on the outer side of the rollers.

[0005] Furthermore, the ultrasonic machine is connected to a power supply circuit via a power line, and an ultrasonic generator is provided on a side of the ultrasonic machine close to the cleaning tank.

[0006] Furthermore, the cleaning tank is arranged in a concave shape, and a drainage valve is provided at the lower end of the cleaning tank.

[0007] Furthermore, the rollers are arranged transversely, and the side arms are grouped in pairs, and 3-4 groups of side arms are provided, and a slide groove is provided on one side of the side arms.

[0008] Furthermore, one end of the side arm away from the roller shaft is swingably connected to the rotating shaft, and one end of the rotating shaft is swingably connected to the blade.

[0009] Furthermore, the rotating shaft is matched with the blades, and the blades are arranged vertically.

[0010] Furthermore, a sliding shaft is slidably connected between each group of side arms, a sleeve is rotatably sleeved on the outer side of the sliding shaft, a telescopic plate is swingably connected to the lower end of the sleeve, and a bracket is provided at the lower end of the telescopic plate.

[0011] Furthermore, the two ends of the sliding shaft slide in the sliding groove of the side arm, and the collar rotates 360 degrees on the outer side of the sliding shaft.

[0012] Furthermore, the telescopic plates are arranged in two sections, and the telescopic plates are slidably nested in a vertical direction. When the telescopic plates slide, the brackets slide synchronously.

[0013] Furthermore, the bracket is arranged in a concave shape, and a plurality of holes are penetrated inside the bracket, and the diameter of the holes is 1-2 cm, and the PCB board is placed on the upper end of the bracket.

[0014] Furthermore, cross bars are arranged between the telescopic plate and the bracket, and two cross bars form a group. A through rod is slidably connected between each group of cross bars, and a cleaning ring surrounds the outer side of the through rod.

[0015] Furthermore, a groove is provided on the inner side of the cross bar, and the groove is arranged in a transverse direction. Both ends of the through-rod slide inside the groove, and the through-rod is located above the bracket.

[0016] Furthermore, the cleaning ring is in a circular ring shape, and the lower end of the cleaning ring is in vertical contact and friction with the upper end of the PCB board.

[0017] Beneficial effects: 1. Since both ends of the sliding shaft slide inside the slide groove of the side arm, when the side arm is at different positions outside the roller shaft, the sliding shaft can slide in different directions inside the slide groove. Due to the different positions of the sliding shaft inside the side arm, when the side arm is at the lower end of the roller shaft, the sliding shaft can slide to the lower end of the side arm. At this time, the sliding shaft drives the bracket to slide toward the end away from the roller shaft. When the side arm is at the upper end of the roller shaft, the side arm slides toward the end close to the roller shaft. Therefore, a weight difference can be generated between the side arms outside the roller shaft, thereby assisting the side arm to rotate outside the roller shaft; 2. Repeat the above steps, the side arm as a whole can be vibrated by the clean water, and the sliding shaft slides on the inner side of the side arm, and the auxiliary side arm as a whole can rotate 360 ​​degrees on the outer side of the roller shaft, so that the PCB board on the upper end of the bracket can be adjusted in the cleaning tank for cleaning, thereby avoiding the accumulation of PCB boards inside the existing cleaning device, resulting in the cleaning device taking a lot of time to clean the PCB board. At the same time, the mobility of the bracket can shorten the cleaning time of the PCB board, thereby making the cleaning efficiency of this cleaning device controllable; 3. When the side arm rotates as a whole through the roller shaft, the collar rotates on the outside of the sliding shaft, and the telescopic plate slides and retracts in the vertical direction as a whole. The bracket can be in a horizontal state as a whole through the telescopic plate and the collar, avoiding the PCB board from tipping over at the upper end of the bracket during the tilting and rotation of the bracket; 4. The cleaning tank is filled with clean water. Due to the drive of the ultrasonic machine, the clean water is in low-frequency vibration as a whole. Due to the vibration of the clean water, the clean water can impact one side of the blade. The blades are arranged vertically, so the blades drive one side of the side arm to swing in a vertical direction through the rotating shaft. At this time, the side arms are driven by the blades, so the side arms can swing through the roller shaft. BRIEF DESCRIPTION OF THE DRAWINGS

Example

[0028] As attached Figure 1 To Attachment Figure 8 As shown: Embodiment 1: A controllable cleaning device for a PCB board comprises an ultrasonic machine 1, a cleaning tank 101 is provided on the side of the ultrasonic machine 1, rollers 2 are rotatably penetrated on both sides of the cleaning tank 101, and side arms 201 are distributed on the outer side of the rollers 2; Wherein: the ultrasonic machine 1 is connected to the power supply circuit through a power line, and an ultrasonic generator is provided on the side of the ultrasonic machine 1 close to the cleaning tank 101, which converts the mains electricity into a high-frequency alternating current signal matching the ultrasonic transducer, drives the ultrasonic transducer to work, and thus cleans the PCB board inside the cleaning tank 101; The cleaning tank 101 is arranged in a concave shape, and a drainage valve is provided at the lower end of the cleaning tank 101; The roller shaft 2 is arranged horizontally, and the side arms 201 are arranged in groups of two each. There are 3-4 groups of side arms 201, and a slide groove is provided on one side of each side arm 201. Figure 4 As shown; Wherein: the PCB board is placed inside the cleaning tank 101, and an ultrasonic generator is provided on the side of the ultrasonic machine 1 close to the cleaning tank 101, which converts the mains electricity into a high-frequency AC signal matching the ultrasonic transducer, drives the ultrasonic transducer to work, and thus cleans the PCB board inside the cleaning tank 101. After cleaning, the sewage is discharged through the drainage valve at the lower end of the cleaning tank 101, and the PCB board is manually taken out from the inside of the cleaning tank 101; Example 2: Refer to the attached manual Figure 1-6It can be seen that the difference between Example 2 and Example 1 is that one end of the side arm 201 away from the roller shaft 2 is swingably connected to the rotating shaft 3, and one end of the rotating shaft 3 is swingably connected to the blade 301; Wherein: the rotating shaft 3 is matched with the blades 301, and the blades 301 are arranged vertically; Wherein: the cleaning tank 101 is filled with clean water, and the clean water is driven by the ultrasonic machine 1, and the clean water is in low-frequency vibration as a whole. Due to the vibration of the clean water, the clean water can impact one side of the blade 301, and the blade 301 is arranged vertically, so the blade 301 drives one side of the side arm 201 to swing in a vertical direction through the rotating shaft 3. At this time, the side arm 201 is driven by the blade 301, so the side arm 201 can swing through the roller 2; Example 3: Refer to the attached manual Figure 1-8 It can be seen that the difference between Example 3 and Examples 1 and 2 is that a sliding shaft 202 is slidably connected between each group of side arms 201, a collar 203 is rotatably sleeved on the outer side of the sliding shaft 202, a telescopic plate 204 is swingably connected to the lower end of the collar 203, and a bracket 205 is provided at the lower end of the telescopic plate 204; Wherein: both ends of the sliding shaft 202 slide inside the sliding groove of the side arm 201, and the collar 203 rotates 360° outside the sliding shaft 202; Both ends of the sliding shaft 202 slide inside the slide groove of the side arm 201, so when the side arm 201 is at different positions outside the roller shaft 2, the sliding shaft 202 can slide in different directions inside the slide groove. Due to the different positions of the sliding shaft 202 inside the side arm 201, a weight difference can be generated between the side arms 201 outside the roller shaft 2, thereby assisting the side arm 201 to rotate outside the roller shaft 2; The telescopic plates 204 are arranged in two sections, and the telescopic plates 204 are vertically slidably nested between each other. When the telescopic plates 204 slide, the brackets 205 slide synchronously. The telescopic plate 204 is used to adjust the vertical distance of the bracket 205, so that the bracket 205 can be moved outside the roller 2. Figure 4 As shown; The bracket 205 is concavely arranged, and a plurality of holes are penetrated inside the bracket 205, and the diameter of the holes is 1-2 cm. The PCB board is placed on the upper end of the bracket 205; Wherein: since both ends of the sliding shaft 202 slide inside the slide groove of the side arm 201, when the side arm 201 is at different positions outside the roller shaft 2, the sliding shaft 202 can slide in different directions inside the slide groove. Due to the different positions of the sliding shaft 202 inside the side arm 201, when the side arm 201 is at the lower end of the roller shaft 2, the sliding shaft 202 can slide to the lower end of the side arm 201. At this time, the sliding shaft 202 drives the bracket 205 to slide toward the end away from the roller shaft 2. When the side arm 201 is at the upper end of the roller shaft 2, the side arm 201 slides toward the end close to the roller shaft 2. Therefore, a weight difference can be generated between the side arms 201 outside the roller shaft 2, thereby assisting the side arm 201 to rotate outside the roller shaft 2. Repeat the above steps, the side arm 201 as a whole can be vibrated by the clean water, and the sliding shaft 202 slides on the inner side of the side arm 201, and the auxiliary side arm 201 can be rotated 360 degrees on the outer side of the roller shaft 2, so that the PCB board on the upper end of the bracket 205 can be adjusted in the cleaning tank 101 for cleaning, thereby avoiding the accumulation of PCB boards in the existing cleaning device, resulting in the cleaning device taking a lot of time to clean the PCB board. At the same time, the mobility of the bracket 205 can shorten the cleaning time of the PCB board, thereby making the cleaning efficiency of this cleaning device controllable; When the side arm 201 rotates as a whole through the roller shaft 2, the collar 203 rotates on the outside of the sliding shaft 202, and the telescopic plate 204 slides and retracts in the vertical direction as a whole. The bracket 205 can be in a horizontal state as a whole through the telescopic plate 204 and the collar 203, so as to avoid the PCB board from tipping over at the upper end of the bracket 205 during the tilting and rotating process of the bracket 205. Please refer to the attached manual for details. Figure 4 As shown; Example 4: Refer to the attached manual Figure 4-7 It can be seen that the difference between Example 4 and Examples 1-3 is that a cross bar 4 is arranged between the telescopic plate 204 and the bracket 205, and each two cross bars 4 form a group. A through rod 401 is slidably connected between each group of cross bars 4, and a cleaning ring 402 surrounds the outer side of the through rod 401. Among them: the inner side of the crossbar 4 is provided with grooves, which are arranged transversely, and the two ends of the through rod 401 slide inside the grooves, and the through rod 401 is located above the bracket 205; The cleaning ring 402 is in a circular ring shape, and the lower end of the cleaning ring 402 is vertically fitted and rubbed against the upper end of the PCB board. The cleaning ring 402 is made of a cleaning material, such as a sponge material; Wherein: the PCB board is placed on the upper end of the bracket 205, and the vibration of the clean water and the vibration generated when the bracket 205 moves are used to slide the penetrating rod 401 inside the groove of the cross bar 4, and the penetrating rod 401 drives the cleaning ring 402 to clean the upper end of the PCB board, thereby assisting the cleaning device to quickly clean the surface of the PCB board.
