Description

Technical Field

[0001] This utility model relates to the field of substrate cleaning technology, and more specifically, to a horizontally tilting oscillating spraying device. Background Technology

[0002] With the rapid development of high-performance electronic devices and artificial intelligence servers, the performance requirements for printed circuit boards (PCBs) are increasing, especially in high-impedance and high-current applications, where higher standards are being set for the precision of circuit line width and spacing. Spraying devices, as key equipment in PCB manufacturing processes such as etching and cleaning, must ensure uniform distribution of the chemical solution to achieve high-quality circuit processing. However, traditional spraying equipment is gradually showing its limitations in handling high-precision circuit processing, failing to meet the demands of the modern electronics industry for refined and uniform processes, prompting the industry to continuously explore more advanced spraying technologies.

[0003] Currently, horizontal oscillating nozzles are commonly used in the spraying process, with a fixed angle between the nozzle and the product surface. This causes the treatment solution to accumulate in certain areas, forming a "pool effect," which affects the flow and exchange of the etching solution. Consequently, it affects the accuracy of line width and line spacing control, and can easily lead to spraying blind spots. This results in slow and uneven etching reactions in these areas, affecting the overall processing consistency.

[0004] Therefore, there is a need to provide a horizontally tilting oscillating spraying device to solve the problem of blind spots that easily occur in existing spraying devices. Utility Model Content

[0005] The main objective of this invention is to provide a horizontally tilting and swinging spraying device, which aims to solve the technical problems mentioned in the background section.

[0006] The present invention adopts the following technical solution:

[0007] A horizontally tilting oscillating spraying device, comprising:

[0008] A guide rail and a swing frame, wherein the swing frame is slidably connected to the guide rail, and a plurality of parallel nozzles are rotatably connected within the swing frame;

[0009] A horizontal swing assembly includes a horizontal drive motor, the output shaft of which is connected to a push rod, and the end of the push rod away from the horizontal drive motor is movably connected to the swing frame so that the swing frame slides along the guide rail.

[0010] A tilting and swaying assembly includes a swaying drive motor, the output shaft of which is connected to a swaying rod, and several nozzles are respectively hinged to the swaying rod to drive the nozzles to tilt and sway around their axes.

[0011] Furthermore, several guide wheels are rotatably connected to opposite sides of the swing frame, and the guide wheels are rollingly connected to the guide rail so that the swing frame swings horizontally along the length of the guide rail.

[0012] Furthermore, a plurality of nozzles are provided on the bottom side of the nozzle, and the plurality of nozzles are evenly distributed along the axial direction of the nozzle. Each nozzle has a spray hole, and the lower end face of the nozzle has a guide that penetrates the spray hole.

[0013] Furthermore, each end of the nozzle is fitted with a limiting ring, which is fixedly connected to the swing frame to prevent the nozzle from moving along its axis. The limiting ring is rotatably connected to the nozzle via a bearing.

[0014] Furthermore, the horizontal swing assembly also includes a horizontal motor spindle, an eccentric wheel is sleeved on the outer side of the horizontal motor spindle, a connecting arm is rotatably connected to the outer side of the eccentric wheel, and the connecting arm is rotatably connected to the push rod to drive the swing frame to reciprocate horizontally along the guide rail.

[0015] Furthermore, a swing connector is connected to the side of the swing frame away from the main shaft of the horizontal motor. A rotating rod is rotatably connected inside the swing connector. The rotating rod is fixedly connected to the push rod so that the push rod is rotatably connected to the swing connector.

[0016] Furthermore, a rocking eccentric block is fixedly provided on the outer side of the nozzle, and a hinge groove is provided at the upper end of the rocking eccentric block. A hinge arm is rotatably connected in the hinge groove, and the hinge arm is fixedly connected to the rocking rod.

[0017] Furthermore, several of the nozzles are arranged at an angle to the swing frame.

[0018] Beneficial effects:

[0019] This invention provides a horizontally tilting oscillating spraying device. A guide rail and an oscillating frame are used, with a horizontal drive motor driving a push rod to drive the oscillating frame to slide horizontally back and forth along the guide rail. This causes the spray nozzle to oscillate horizontally. During the horizontal oscillation, the nozzle array reciprocates along the width of the workpiece, ensuring the liquid is evenly distributed throughout the working area. This provides a consistent liquid supply, effectively reducing the pooling effect caused by prolonged local dwell time, enhancing the fluidity and exchange capacity of the treatment liquid, and improving the uniformity and precision of the overall etching and cleaning. Furthermore, the spray nozzle, hinged to a oscillating rod and driven by an oscillating drive motor, achieves tilting oscillation around its own axis. This allows the nozzles to dynamically change angles during the oscillation, breaking the tendency for liquid to accumulate in a specific direction and ensuring the spray direction covers multiple angle areas. This significantly improves the spray coverage between spray nozzles, achieving comprehensive and uniform spraying of the liquid. Attached Figure Description

[0030] Reference Figures 1 to 4 This utility model proposes a horizontal tilting swing spraying device, including: a guide rail 1 and a swing frame 2, wherein the swing frame 2 is slidably connected to the guide rail 1, and a plurality of parallel spray pipes 3 are rotatably connected inside the swing frame 2.

[0031] A horizontal swing assembly 4 includes a horizontal drive motor 410. The output shaft of the horizontal drive motor 410 is connected to a push rod 420. One end of the push rod 420 away from the horizontal drive motor 410 is movably connected to the swing frame 2 so that the swing frame 2 slides along the guide rail 1.

[0032] The tilting and swaying assembly 5 includes a swaying drive motor, the output shaft of which is connected to a swaying rod 510. Several nozzles 3 are respectively hinged to the swaying rod 510 to drive the nozzles 3 to tilt and sway around its axis.

[0033] In the above embodiment, the device includes a guide rail 1, a swing frame 2, several nozzles 3, a horizontal swing assembly 4, and a tilting swing assembly 5. The guide rail 1 is mounted on the main body of the device and serves as the sliding reference for the swing frame 2. The swing frame 2 is slidably connected to the guide rail 1 and can reciprocate horizontally under the guidance of the guide rail 1. The multiple nozzles 3 are arranged parallel to each other at uniform intervals within the swing frame 2 and are rotatably connected to the swing frame 2 to facilitate tilting and swinging of each nozzle 3 around its own axis while maintaining horizontal movement. The horizontal swing assembly 4 includes a horizontal drive motor 410 and a push rod 420 connected to its output shaft. The other end of the push rod 420 is movably connected to the swing frame 2. When the horizontal drive motor 410 is running, the push rod 420 reciprocates by pushing and pulling, thereby driving the swing frame 2 to slide along the guide rail 1, realizing the overall reciprocating swinging motion of the nozzles 3 in the horizontal direction.

[0034] The tilting and swaying assembly 5 consists of a swaying drive motor, an output shaft, and a swaying rod 510 hinged to the nozzle 3. The output shaft of the swaying drive motor drives the swaying rod 510 to reciprocate, pushing and pulling. Through the hinge between the nozzle 3 and the swaying rod 510, the nozzle 3 performs a periodic tilting and swaying motion around its axis. This allows the nozzle to slide back and forth horizontally with the entire swaying frame 2 during operation, ensuring comprehensive coverage of the entire workpiece width and guaranteeing complete coverage of the spray area. This is especially beneficial in high-density circuit areas, achieving efficient and uniform liquid supply, mitigating the pooling effect caused by liquid accumulation, and improving the dynamic exchange efficiency of the treatment liquid. Simultaneously, the nozzle 3 itself can dynamically adjust the nozzle angle through tilting and swaying, continuously changing the spray direction, increasing the scouring angle and coverage path of the liquid flow, further improving spray uniformity. This is particularly effective in the gap areas between the nozzles 3, increasing the liquid contact density and cleaning depth, avoiding spray dead zones, and ensuring the uniformity and consistency of the etching reaction on the entire workpiece surface. This makes it suitable for the printed circuit board manufacturing environment, which demands extremely high spraying precision and process stability.

[0035] refer to Figure 1 and Figure 2In one embodiment, a plurality of guide wheels 6 are rotatably connected to opposite sides of the swing frame 2, and the guide wheels 6 are rolledly connected to the guide rail 1 so that the swing frame 2 swings horizontally along the length direction of the guide rail 1.

[0036] In the above embodiment, multiple guide wheels 6 are respectively provided on the left and right sides of the swing frame 2, and each guide wheel 6 is rotatably connected to the swing frame 2 via a rotating shaft. The guide wheel 6 contacts the rolling surface of the guide rail 1 and maintains a rolling engagement relationship. Thus, during the movement of the swing frame 2, the guide wheel 6 rolls along the guide rail 1, significantly reducing the frictional resistance when the frame slides and improving the stability and smoothness of the swing. Compared with the traditional slider or direct sliding structure, the rolling connection between the guide wheel 6 and the guide rail 1 can effectively reduce positioning errors caused by friction and wear on the guide rail 1, thereby improving the service life and maintenance efficiency of the equipment. In addition, this structure can maintain good straightness control under high-speed working conditions, ensuring the precise repeatability of the spray path and helping to further improve the uniformity of spraying and processing consistency.

[0037] refer to Figure 1 In one example, a plurality of nozzles 7 are provided on the bottom side of the nozzle 3. The plurality of nozzles 7 are evenly distributed along the axial direction of the nozzle 3. Each nozzle 7 has a spray hole and a flow guide groove penetrating the spray hole is provided on the lower end face of the nozzle 7.

[0038] In the above embodiments, each nozzle 3 is equipped with multiple nozzles 7 at its bottom. The nozzles 7 are arranged at equal intervals along the axial direction of the nozzle 3, thus forming a continuous and uniform spray array. Each nozzle 7 has a spray hole on its central axis to atomize the liquid and spray it onto the surface of the workpiece to be treated, ensuring that there are no dead corners in the spray area. To improve the falling path and distribution consistency of the liquid, a guide groove penetrating the spray hole is provided on the lower end face of each nozzle 7. The geometric design of the guide groove allows the sprayed liquid to quickly form a directional liquid flow after leaving the spray hole, effectively reducing the deviation and diffusion of the atomized liquid in the air, improving the spray hit rate, not only improving the utilization efficiency of the liquid and avoiding waste, but also strengthening the impact force and cleaning ability below the nozzle 7.

[0039] In one embodiment, limiting rings 8 are fitted at both opposite ends of the nozzle 3. The limiting rings 8 are fixedly connected to the swing frame 2 to prevent the nozzle 3 from moving along its axis. The limiting rings 8 are rotatably connected to the nozzle 3 through bearings.

[0040] In the above embodiment, limit rings 8 are installed at both ends of the nozzle 3. The limit rings 8 are tightly fitted onto the nozzle 3 and fixedly connected to the swing frame 2 by an interference fit. The inner hole of the limit ring 8 is rotatably connected to the outer wall of the nozzle 3 through a bearing, allowing the nozzle 3 to rotate within the limit ring 8. This structure ensures that the nozzle 3 only rotates and does not move axially when it tilts and swings, preventing axial movement from affecting the alignment position of the nozzle 7 array. On the one hand, it maintains the spray area of ​​the nozzle in the designed position, avoiding spray deviation caused by offset; on the other hand, it also reduces vibration and resonance during the swinging process, improving the dynamic stability and structural reliability of the entire device.

[0041] refer to Figures 1 to 3 In one embodiment, the horizontal swing assembly 4 further includes a horizontal motor spindle 430, an eccentric wheel 440 is sleeved on the outer side of the horizontal motor spindle 430, a connecting arm 450 is rotatably connected to the outer side of the eccentric wheel 440, and the connecting arm 450 is rotatably connected to the push rod 420 to drive the swing frame 2 to reciprocate horizontally along the guide rail 1.

[0042] In the above embodiment, the output end of the horizontal drive motor 410 is connected to a horizontal motor main shaft 430. An eccentric wheel 440 is sleeved on the main shaft. The outer ring of the eccentric wheel 440 is rotatably connected to a connecting arm 450. One end of the connecting arm 450 is rotatably connected to a push rod 420. The push rod 420 is movably connected to the swing frame 2. When the motor main shaft rotates, the eccentric wheel 440 rotates around its central axis, causing the connecting arm 450 to perform periodic eccentric motion, thereby driving the push rod 420 to perform reciprocating linear movement. The movement of the push rod 420 then causes the swing frame 2 to slide back and forth along the guide rail 1, realizing the overall horizontal swing of the nozzle 3. The advantage of using the eccentric wheel 440 for driving is that the structure is compact, the operation is smooth, and the driving force is evenly distributed. It can avoid the impact and speed change caused by uneven motor load, and maintain the stability and continuity of the spraying process.

[0043] refer to Figure 1 and Figure 2 In one embodiment, a swing connector 460 is connected to the side of the swing frame 2 away from the horizontal motor spindle 430. A rotating rod is rotatably connected inside the swing connector 460. The rotating rod is fixedly connected to the push rod 420 so that the push rod 420 is rotatably connected to the swing connector 460.

[0044] In the above embodiment, to further improve the connection stability and operational reliability of the pushing mechanism, a swing connector 460 is connected to the end of the swing frame 2 away from the horizontal motor main shaft 430. The swing connector 460 is fixed to the swing frame 2 by screwing or welding, and has a shaft hole inside that rotatably connects to a rotating rod. The push rod 420 is fixed to one end of the rotating rod by a key connection or pin. The rotating rod can rotate freely within the swing connector 460, realizing the rotational connection of the push rod 420 relative to the swing frame 2. This structural design enhances the flexible linkage capability of the push rod 420 during movement, effectively compensating for attitude deviations caused by minor unevenness of the guide rail 1, assembly errors of the connector, or eccentricity of the motor rotation, reducing the risk of structural jamming or linkage failure, and ensuring smooth overall swinging process.

[0045] refer to Figure 1 , Figure 2 and Figure 4 In one embodiment, a rocking eccentric block 520 is fixedly provided on the outer side of the nozzle 3. A hinge groove is provided at the upper end of the rocking eccentric block 520. A hinge arm 530 is rotatably connected in the hinge groove. The hinge arm 530 is fixedly connected to the rocking rod 510.

[0046] In the above embodiment, a rocking eccentric block 520 is fixedly installed on the outer wall of each nozzle 3. A hinge groove is machined at the upper end of the rocking eccentric block 520. The hinge arm 530 connected to the rocking rod 510 is inserted into the hinge groove for rotatable connection. As the rocking drive motor drives the rocking rod 510 to reciprocate, the hinge arm 530 causes the eccentric block to produce a small-amplitude periodic sway, thereby driving the nozzle 3 to tilt and rock around its own axis. Without affecting the spray direction along the axis of the nozzle 3, the angle coverage capability of the nozzle 7 is enhanced by continuous changes in a small angle, allowing the liquid to impact the surface to be treated from multiple directions, effectively destroying the surface liquid film and bubble deposition.

[0047] In one embodiment, several of the nozzles 3 are arranged at an angle to the swing frame 2.

[0048] In the above embodiment, the multiple nozzles 3 are not orthogonally arranged to the swing frame 2, but rather at a certain angle to it. This angle is a preset angle and can be adjusted within the range of 5° to 30° according to the spraying requirements. This inclined arrangement allows the nozzles to form an oblique angle relative to the workpiece surface during spraying, thereby enhancing the shear flow effect of the liquid and helping to improve the penetration and coverage density of the spray. Especially when processing workpieces with micro-cracks or grooves on the surface, it can more effectively guide the liquid into them for full action. The angle setting can also be combined with the tilting and swinging motion to generate a composite spray path, increasing the diversity of the liquid trajectory on the workpiece surface, avoiding flow marks or insufficient rinsing caused by spraying in a single direction, and improving the processing quality and consistency.

[0049] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
