[0040] With the development of the electronics industry, the existing PCB circuit boards have higher and higher requirements for density and aperture. At present, the market generally adopts ultrasonic horizontal conveying to immerse PCB boards. The horizontal conveying method drives the PCB board to move by friction between the rolling reel and the PCB board, and the ultrasonic device is set at the top and bottom of the rolling reel to clean the PCB board on the rolling reel.

[0041] During the conveying process, part of the roller blocks the PCB board, resulting in insufficient cleaning of the PCB board, affecting the cleaning effect. In addition, since the roller is in contact with the PCB board, the surface of the PCB board is easily scratched and the thin board is easily folded.

[0042] In view of the above technical problems, the present application optimizes the direction of action of the ultrasonic cleaning equipment, changing the traditional horizontal ultrasonic cleaning method into a vertical ultrasonic cleaning method to solve the problems caused by the above-mentioned roller blocking the PCB board and the contact between the roller and the PCB board surface.

[0043] The main purpose of this technical solution is to propose an ultrasonic immersion cleaning mechanism, which aims to solve the technical problems that in the existing ultrasonic horizontal conveying immersion cleaning process, the PCB board is blocked by the roller, resulting in insufficient cleaning, and the PCB board surface is easily scratched due to the surface contact between the roller and the PCB board, and the thin plate is easily folded.

[0044] See also Figure 1-Figure 4 In one embodiment of the ultrasonic cleaning mechanism of the present application, the ultrasonic cleaning mechanism comprises:

[0045] Box 30;

[0046] A conveying device 31, the conveying device 31 is used to clamp the plate-shaped workpiece and drive the workpiece to move in the box 30;

[0047] A plurality of ultrasonic vibration plates 7 are perpendicular to the bottom surface of the box body 30 and connected to two sides of the box body. The ultrasonic vibration plates 7 are used to clean the two side surfaces of the workpiece moving in the box body 30 .

[0048] In this embodiment, the box 30 is filled with liquid for cleaning the workpiece, and an opening is provided at the top of the box 30. The conveying device 31 is provided at the top of the box 30, and the conveying device 31 clamps one end of the workpiece so that the length direction or width direction of the workpiece is perpendicular to the bottom surface of the box, or the length direction or width direction of the workpiece is inclined to the bottom surface of the box by clamping the workpiece. While the conveying device clamps the workpiece, the conveying device drives the workpiece into the box through the opening, and drives the workpiece to move in the box 30 along the length direction of the box. During the movement, since the multiple ultrasonic vibrating plates 7 are perpendicular to the bottom surface of the box and are located on both sides of the box, the ultrasonic vibrating plates 7 generate cavitation through ultrasonic waves to clean the moving workpiece located between the ultrasonic vibrating plates 7 on both sides.

[0049] The ultrasonic cleaning mechanism of the present technical solution clamps the workpiece through a conveying device and drives the workpiece to move in a box, and cleans both side surfaces of the workpiece moving in the box through a plurality of ultrasonic vibration plates. Since there is no roller between the ultrasonic vibration plate and the workpiece, not only the effective area of ​​the ultrasonic vibration plate on the workpiece is maximized and the cleaning efficiency is improved, but also the phenomenon of the roller scratching the workpiece and causing the workpiece to fold is avoided.

[0050] Furthermore, the conveying device 31 includes a transmission belt (not shown) and a plurality of grippers (not shown) connected to the transmission belt, and the grippers are used to grip the workpiece. The conveying device drives the transmission belt through a driving member to rotate the transmission belt, and while the transmission belt rotates, the grippers on the transmission belt are driven, so that the grippers and the workpieces gripped by the grippers move together in the box.

[0051] It is worth noting that the driving member structure of the conveying device 31 of this embodiment, the method of driving the transmission belt, the structure of the transmission belt and the structure of the gripper all adopt existing conventional technologies and will not be described in detail here.

[0052] Conventional horizontal ultrasonic immersion cleaning drives the workpiece to be transported through the friction of the reel. When the workpiece enters the water tank, the water retaining pressure reel must be lifted up. Due to the limited width of the workpiece, a single workpiece cannot cover the conveying surface of the reel. At this time, water leakage will inevitably occur at the water retaining position. Especially when producing thick plates, the water leakage problem is particularly serious, and water leakage will affect the height of the water tank. When the liquid level of the water tank does not reach the required working liquid level, the ultrasonic vibration plate cannot work normally, which in turn affects production efficiency. If you want to solve this problem, you need to lengthen the length of the water tank, increase the total capacity of the water tank, increase the amount of water replenishment, and use a more powerful water replenishment pump. Therefore, this approach is bound to increase the total length of the machine body and the power consumption of the unit.

[0053] In order to solve the above-mentioned technical problems, the ultrasonic immersion cleaning mechanism of the present application is provided with a buffer zone, which buffers the transition and effectively avoids the low liquid level phenomenon, thereby ensuring continuous plate production. At the same time, by adding a gate between the buffer zone and the ultrasonic immersion cleaning zone, the phenomenon of water leakage is effectively prevented.

[0054] Specifically, the box body is connected with a first buffer gate 13, a first immersion gate 14, a second immersion gate 15, and a second buffer gate 16 in sequence, a first buffer zone 1 is formed between the first buffer gate 13 and the first immersion gate 14, an immersion zone 2 is formed between the first immersion gate 14 and the second immersion gate 15, and a second buffer zone 3 is formed between the second immersion gate 15 and the second buffer gate 16.

[0055] Furthermore, the bottom of the first buffer zone 1 is connected to a first buffer water inlet pipeline and a first buffer water discharge pipeline, the first buffer water inlet pipeline is provided with a first buffer water inlet pump 10, and the first buffer water discharge pipeline is provided with a drain valve 6. The bottom of the second buffer zone 3 is connected to a second buffer water inlet pipeline and a second buffer water discharge pipeline, the second buffer water inlet pipeline is provided with a second buffer water inlet pump 12, and the second buffer water discharge pipeline is provided with a drain valve. The bottom of the immersion zone 2 is connected to an immersion water inlet pipeline, and the immersion water inlet pipeline is provided with an immersion water inlet pump 11.

[0056] During operation, the immersion area 2 and the second buffer area 3 are filled with liquid medicine through the immersion water pump 11 and the second buffer water pump 12 provided at the bottom of the immersion area 2 and the second buffer area 3, respectively, and the liquid levels of the immersion area 2 and the second buffer area 3 are made the same. Subsequently, the first buffer area gate 13 is opened, and the workpiece is clamped by the conveying device 31 provided on the box body 30, so that the workpiece enters the first buffer area 3 in a manner perpendicular to the box body. Subsequently, the first buffer area 3 is filled with liquid medicine through the first buffer water pump 10, so that the liquid level of the first buffer area 3 is the same as the liquid level of the immersion area 2. Subsequently, the first immersion gate 14 is opened to allow the workpiece to enter the immersion area 2. The workpiece is cleaned in the immersion area 2 by a vertically arranged ultrasonic vibration plate. After the cleaning is completed, the second immersion gate 15 is opened to allow the workpiece to leave the immersion area 2 and enter the second buffer area 3. Subsequently, the second immersion gate 15 between the immersion area 2 and the second buffer area 3 is closed to discharge the liquid medicine in the second buffer area 3. Finally, the second buffer gate 16 is opened to drive the workpiece to leave the second buffer zone 3 .

[0057] In summary, by adding the first buffer zone 1 and the second buffer zone 3 on both sides of the ultrasonic immersion zone, since the liquid levels of the first buffer zone 1 and the second buffer zone 2 are the same as the liquid level of the immersion zone 2 during the process of conveying the workpiece into the immersion zone 2 and conveying the workpiece out of the immersion zone 2, it is possible to ensure that the liquid level in the immersion zone 2 is always maintained at the working height to avoid the phenomenon of liquid level reduction, thereby ensuring the normal operation of the ultrasonic vibration plate and ensuring the continuous production of workpieces and improving production efficiency; and since the first immersion gate 14 and the second immersion gate 15 are respectively arranged between the immersion zone 2 and the first buffer zone 1 and between the immersion zone 2 and the second buffer zone 3, it is possible to effectively avoid leakage of the liquid and water leakage.

[0058] It is worth noting that the first immersion gate 14, the second immersion gate 15, the first buffer gate 13, and the second buffer gate 16 of this embodiment all adopt a movable switch gate structure, and the gate is driven by the cylinder to achieve the effect of controlling the switch. The above-mentioned gate structure and the connection and installation method between the gate and the cylinder all adopt existing conventional technologies, which will not be described one by one here.

[0059] Preferably, when the conveying device 31 drives the workpiece to move in the immersion zone 2, in order to ensure the stability of the workpiece movement, avoid the workpiece from shifting in the immersion zone 2, and avoid the workpiece from escaping from the grip of the conveying device's clamps, the ultrasonic immersion mechanism is also provided with a guide device 9.

[0060] For details, please refer to Figure 2, the guide device 9 is provided with two rows of mutually parallel guide members, the guide members are vertically connected to the box body and are located in the immersion area 2. A guide gap 44 is provided between the two rows of mutually parallel guide members, and the guide gap 44 extends along the length direction of the box body 30. In this embodiment, since the two rows of guide members are parallel to each other and vertically arranged, the conveying device can use the guide gap 44 between the two rows of guide members to limit the workpiece moving in the immersion area to prevent the workpiece from shifting during the movement. In this embodiment, the guide member is made of Teflon wire. The use of a linear structure guide member can not only ensure the limiting effect, but also because the linear contact area is smaller, it does not affect the cleaning of the workpiece by the ultrasonic vibration plate 7.

[0061] In addition, in order to ensure the stability of the workpiece in the process of the conveying device 31 driving the workpiece to move in the first buffer zone 1 and the second buffer zone 3, to prevent the workpiece from being offset in the first buffer zone 1 and the second buffer zone 3, and to prevent the workpiece from being separated from the grip of the gripper of the conveying device, the ultrasonic immersion cleaning mechanism is also provided with a limiting device 8. The limiting device 8 is provided with two rows of mutually parallel limiting members, and the limiting members are vertically connected to the box body and are located in the first buffer zone 1 and the second buffer zone 3. A limiting gap 41 is provided between the two rows of limiting members, and the limiting gap 41 extends along the length direction of the box body. In this embodiment, since the two rows of limiting members are parallel to each other and vertically arranged, the conveying device can use the limiting gap 41 between the two rows of limiting members to limit the workpiece moving in the first buffer zone 1 and the second buffer zone 3, and prevent the workpiece from being offset during the movement. In this embodiment, the limiting member adopts a row of rollers.

[0062] Since the ultrasonic vibration plate of the existing ultrasonic cleaning equipment is fixed and cannot be adjusted, the ultrasonic vibration plate cannot achieve the best immersion effect when producing workpieces of different types and sizes. In order to solve this problem, the ultrasonic immersion cleaning mechanism of the present application is provided with an adjustment component, which can freely adjust the distance from the ultrasonic vibration plate to the workpiece according to different workpiece types.

[0063] For details, please refer to Figure 3-Figure 4 The adjustment assembly includes a guide rod 23 and a transmission rod. The guide rod 23 is transmission-connected to the transmission rod. The guide rod 23 is rotatably connected to the box body 30, and the ultrasonic vibration plate 7 is movably connected to the transmission rod.

[0064] Further, one end of the guide rod 23 is connected to a rotating handle 24, and the rotating handle 24 can facilitate the user to rotate the guide rod 23. The guide rod 23 is connected to a first fixing member 18, and a bearing is arranged in the first fixing member 18. The first fixing member 18 is fixedly connected to one side of the box body, and the guide rod 23 is rotatably fixed to one side of the box body by passing through the bearing. The transmission rod includes a first screw rod 21 and a second screw rod 22, and the first screw rod 21 and the second screw rod 22 are located at the bottom of the box body and are arranged perpendicular to the guide rod 23. One end of the first screw rod 21 and the second screw rod 22 is connected to a cylindrical gear 17, and the cylindrical gear 17 is meshed with the other end of the guide rod 23, so that the first screw rod 21 and the second screw rod 22 are transmission-connected with the guide rod 23. Under the drive of the guide rod 23, the first screw rod 21 and the second screw rod 22 rotate with the rotation of the guide rod 23. Since the ultrasonic vibration plates 7 are located on both sides of the immersion area and are arranged opposite to each other, the first screw 21 is connected to the ultrasonic vibration plate on one side of the box, and the second screw 22 is connected to the ultrasonic vibration plate on the other side of the box. The bottom of the ultrasonic vibration plate 7 is fixedly connected to a support plate 19, and a nut is provided on the support plate 19. The first screw 21 and the second screw 22 are respectively threadedly connected to the nuts on the support plates on both sides, so that the support plate 19 moves with the rotation of the guide rod 23 under the transmission of the first screw 21 and the second screw 22.

[0065] Preferably, since the second screw 22 is longer than the first screw 21, the second screw 22 is connected to the second fixing member 20. A bearing is arranged inside the second fixing member 20, and the second fixing member 20 is fixedly connected to the bottom of the box body. The second screw 22 is rotatably fixed to the bottom surface of the box body by passing through the bearing, thereby improving the stability of the rotation of the second screw 22. In addition, in order to improve the stability of the ultrasonic vibration plate 7 when moving, the first slide rail 42 and the second slide rail 43 are connected to the two sides of each group of relatively arranged ultrasonic vibration plates 7, respectively. The first slide rail 42 and the second slide rail 43 are arranged parallel to the first screw 21 and the second screw 22, and the two ends of the first slide rail 42 and the second slide rail 43 are respectively fixedly connected to the box body. With such an arrangement, under the limiting action of the first slide rail 42 and the second slide rail 43, the movement of the ultrasonic vibration plate 7 is more stable and accurate. In addition, a distance scale is installed on the box body, and the distance moved by the ultrasonic vibration plate 7 can be accurately grasped by the scale.

[0066] This embodiment also provides an ultrasonic vertical immersion cleaning method, including the above-mentioned ultrasonic immersion cleaning mechanism, and the ultrasonic immersion cleaning method includes the following steps:

[0067] S10: The workpiece enters the ultrasonic immersion zone through the conveying device;

[0068] S20: cleaning the two sides of the workpiece by means of a vertically arranged ultrasonic vibration plate;

[0069] S30: Make the workpiece leave the ultrasonic immersion zone.

[0070] Furthermore, the step of S10: allowing the workpiece to enter the ultrasonic immersion zone through the conveying device specifically includes:

[0071] S1: Separate the box into a first buffer zone, an ultrasonic immersion zone, and a second buffer zone in sequence through gates, and fill the ultrasonic immersion zone and the second buffer zone with liquid medicine so that the liquid levels of the ultrasonic immersion zone and the second buffer zone are the same;

[0072] S2: Open the gate of the first buffer zone, and clamp the workpiece by the conveying device to allow the workpiece to enter the first buffer zone;

[0073] S3: Filling the first buffer area with liquid medicine so that the liquid level of the first buffer area is the same as the liquid level of the ultrasonic immersion area;

[0074] S4: opening the gate between the first buffer area and the ultrasonic immersion area to allow the workpiece to enter the ultrasonic immersion area.

[0075] Furthermore, the step of making the workpiece leave the ultrasonic immersion zone in S30 includes:

[0076] S31: opening the gate between the ultrasonic immersion zone and the second buffer zone, so that the workpiece leaves the ultrasonic immersion zone and enters the second buffer zone;

[0077] S32: closing the gate between the ultrasonic immersion area and the second buffer area to discharge the liquid in the second buffer area;

[0078] S33: Open the second buffer gate to allow the workpiece to leave the second buffer.

[0079] The ultrasonic vertical immersion method of this embodiment clamps the workpiece by a conveying device and drives the workpiece to move in the box in a manner perpendicular to the box, and cleans the workpiece moving in the box by an ultrasonic vibration plate. Since there is no roller between the ultrasonic vibration plate and the workpiece, not only the effective area of ​​the ultrasonic vibration plate on the workpiece is maximized, the cleaning efficiency is improved, but also the phenomenon of the roller scratching the workpiece and the workpiece bending can be avoided. In addition, by adding a first buffer zone and a second buffer zone on both sides of the ultrasonic immersion zone, the liquid levels of the first buffer zone and the second buffer zone are the same as the liquid level of the ultrasonic immersion zone during the process of the workpiece entering and leaving the ultrasonic immersion zone, so the liquid level of the ultrasonic immersion zone can be ensured to always maintain at the working height, avoiding the phenomenon of liquid level reduction, thereby ensuring the normal operation of the ultrasonic vibration plate, ensuring the continuous production of workpieces, and improving production efficiency. In addition, since gates are respectively provided between the ultrasonic immersion zone and the first buffer zone, and between the ultrasonic immersion zone and the second buffer zone, the leakage of the liquid and the phenomenon of water leakage can be effectively avoided.

[0080] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
