Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology, specifically a high-precision horizontal swing spraying device. Background Technology

[0002] In precision manufacturing processes such as developing and etching, the uniformity and stability of the spray system directly determine the surface treatment accuracy and yield of the products. If the spray liquid flow is uneven or the pressure fluctuates, it can easily lead to differences in liquid film thickness, causing local insufficient development, over-etching, or residual defects. These problems are more pronounced when processing micron-scale structures or large-size substrates.

[0003] In precision processes such as developing and etching, the uniformity and coverage of the spray system directly affect the surface treatment quality and yield of the products. Traditional spray systems mostly adopt a fixed structure, and the nozzle position and spray angle are not adjustable, resulting in uneven distribution of spray liquid. This makes it difficult to meet the full surface coverage requirements of complex workpieces or large-sized products. Especially when processing edge areas or three-dimensional structures, the fixed spray direction is prone to liquid accumulation or blind spots, causing problems such as local over-etching or insufficient developing.

[0004] Therefore, a high-precision horizontal swing spraying device is proposed to solve the problem of the non-adjustable nozzle position and spray angle. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a high-precision horizontal swing spraying device, which solves the problem of the inability to adjust the nozzle position and spray angle.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-precision horizontal swing spraying device, comprising spraying components arranged symmetrically in a frame, wherein the spraying components reciprocate laterally within the frame, a spraying area is provided between two spraying components, and a plurality of nozzles facing the spraying area are inclinedly arranged on the spraying components, the nozzles being used to spray liquid into the spraying area.

[0007] Preferably, the spray assembly includes a frame and a plurality of spray pipes. The cross-sectional shape of the frame is U-shaped. The spray pipes are detachably mounted on the frame, and the plurality of spray pipes are distributed at equal intervals on the frame. The nozzles are mounted on the spray pipes, and the hoses, spray pipes and nozzles are connected in sequence.

[0008] Preferably, a drive unit is provided on the frame, the spray assembly is provided on the support unit inside the frame, and the spray assembly moves linearly on the support unit. The drive unit is used to drive the spray assembly to move reciprocally in the lateral direction on the support unit.

[0009] Preferably, the bearing unit includes a support plate, a slide rail, and rollers. The support plate is fixed laterally within the frame, the slide rail is mounted on the support plate, and the rollers are mounted on the side of the spray assembly near the slide rail via a rotating shaft, and the rollers are in a rolling connection with the slide rail.

[0010] Preferably, the drive unit includes a drive motor, a rotating rod, an eccentric wheel, a rotating sleeve, and a support block. The drive motor, the rotating rod, and the support block are connected sequentially from top to bottom. The eccentric wheel is rotatably connected inside the rotating sleeve and fixed to the outside of the rotating rod. The rotating sleeve is detachably connected to the spray assembly through a connector.

[0011] Preferably, the support plate is provided with a mounting bracket, and a lubrication unit is provided on the mounting bracket corresponding to the roller. The lubrication unit is used to reduce the friction between the roller and the slide rail.

[0012] Preferably, the lubrication unit includes a cylinder and a ball bearing. The bottom surface of the cylinder has a connecting hole, and the ball bearing is rotatably connected in the connecting hole. The top surface of the cylinder has an opening, and the cylinder is connected to the cover through the opening. The outer circumferential surface of the roller has an inwardly recessed arc-shaped groove, and the ball bearing is rotatably connected in the arc-shaped groove. The size of the ball bearing is adapted to the size of the arc-shaped groove.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. This high-precision horizontal swing spraying device achieves dynamic coverage through the combination of reciprocating spray components and inclined nozzles, avoiding the problems of liquid accumulation or blind spots caused by fixed nozzle paths. It enables the liquid to cover the material surface more evenly, improving the accuracy and efficiency of spraying, effectively reducing local defects, and avoiding uneven liquid distribution that affects the surface treatment accuracy.

[0015] 2. This high-precision horizontal oscillating spraying device, through its lubrication unit, effectively reduces the friction between the rollers and the slide rail, lowering the motion resistance. The lubricating oil forms a lubricating film on the contact surface between the rollers and the slide rail, reducing dry friction, lessening the load on the drive unit, and improving the response speed and operating efficiency of the spraying components. In addition, the lubrication unit can also extend the service life of the rollers and slide rail, reduce wear and micro-cracks, and lower maintenance costs and component replacement frequency, making it particularly suitable for high-frequency, long-cycle working environments.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figure 1-8 The high-precision horizontal swing spraying device in this embodiment includes a spraying assembly 2 arranged symmetrically in the frame 1. The spraying assembly 2 reciprocates in the horizontal direction in the frame 1. A spraying area 11 is provided between the two spraying assemblies 2. Several nozzles 3 are inclinedly arranged on the spraying assembly 2 facing the spraying area 11. The nozzles 3 are used to spray liquid into the spraying area 11.

[0028] In application, the material is placed in the spraying area 11, and then the spraying assembly 2 is supplied with liquid through the hose 4. The liquid is then sprayed onto the material through the nozzle 3. While the nozzle 3 is spraying the liquid, the spraying assembly 2 will also reciprocate within the frame 1, so that the nozzle 3 reciprocates while spraying the liquid, ensuring that the liquid is sprayed evenly onto the material and avoiding blind spots that could affect the spraying quality.

[0029] Specifically, the hose 4 is a Teflon corrugated hose 4. The hose 4 can be bent as the spray assembly 2 moves, and it is made of Teflon material, which has a low coefficient of friction and excellent chemical resistance, which is beneficial for transporting liquid. In addition, the spray assembly 2 is connected to an external water supply system through the hose 4. The water supply system supplies liquid to the hose 4. Its specific structure is well known to those skilled in the art, and will not be described in detail in this embodiment.

[0030] It should be noted that the two spraying components 2 reciprocate synchronously. After they move, they can spray the material on the upper and lower sides of the spraying area 11 synchronously through the corresponding nozzles 3, so as to improve work efficiency. Synchronous spraying can also ensure the consistency of the spraying quality on the upper and lower sides of the material.

[0031] It is known that when the inclined nozzle 3 sprays liquid, the liquid can spread at a non-vertical angle, effectively covering the edges, grooves or complex three-dimensional surfaces of the material, reducing the blind spot problem of traditional vertical spraying. At the same time, driven by the reciprocating spray assembly 2, the nozzle 3 can form a dynamic coverage of the spray trajectory, avoiding the repetition of fixed paths, making the liquid flow distribution more uniform, reducing the difference in liquid film thickness, and thus improving the consistency of the development and etching processes.

[0032] Furthermore, the spray assembly 2 includes a frame 21 and several spray pipes 22. The cross-sectional shape of the frame 21 is U-shaped. The spray pipes 22 are detachably mounted on the frame 21, and the several spray pipes 22 are distributed at equal intervals on the frame 21. The nozzles 3 are mounted on the spray pipes 22, and the water supply system, hose 4, spray pipes 22 and nozzles 3 are connected in sequence. Specifically, a pressure gauge is mounted on the hose 4.

[0033] It should be noted that during spraying, the liquid is supplied by the water supply system and flows sequentially through the hose 4, spray pipe 22, and nozzle 3. In addition, each spray pipe 22 is installed on the frame 21 via a separate quick-release connector and is connected to the hose 4. The quick-release connector allows for quick installation and removal of the spray pipe 22 without complicated tools or long-term operation, facilitating cleaning or replacement of the spray pipe 22. Furthermore, the individual quick-release connector can prevent all spray pipes 22 from shutting down when cleaning or replacing individual spray pipes 22. It should also be noted that the individual quick-release connector can open and close the communication channel between the spray pipe 22 and the hose 4. The specific structure and connection method are well known to those skilled in the art and will not be described in detail in this embodiment.

[0034] In one specific embodiment, the nozzle 3 is detachably fixed to the spray pipe 22.

[0035] Example 2:

[0036] The basic content is the same as in Example 1, except that:

[0037] Please see Figure 1-4 In this embodiment, a drive unit 5 is provided on the frame 1, and the spray assembly 2 is provided on the support unit 6 inside the frame 1. The spray assembly 2 performs linear motion on the support unit 6, and the drive unit 5 is used to drive the spray assembly 2 to perform reciprocating motion in the lateral direction on the support unit 6.

[0038] It should be noted that after the drive unit 5 is running, it causes the spray assembly 2 to reciprocate on the support unit 6, thereby causing the tilted nozzle 3 to reciprocate when spraying liquid.

[0039] It should also be noted that the drive unit 5 includes, but is not limited to, linear motors, pneumatic cylinders and electric push rods, which are technologies well known to those skilled in the art. The drive unit 5 only needs to enable the spray assembly 2 to perform reciprocating motion, and will not be described in detail in this embodiment. The bearing unit 6 includes, but is not limited to, ball bearing guides, flexible hinge guide mechanisms and air bearing guides, which are technologies well known to those skilled in the art. The bearing unit 6 only needs to enable the spray assembly 2 to perform linear motion, and will not be described in detail in this embodiment.

[0040] Specifically, the bearing unit 6 includes a support plate 61, a slide rail 62, and a roller 63. The support plate 61 is fixed horizontally inside the frame 1, the slide rail 62 is mounted on the support plate 61, and the roller 63 is mounted on the side of the spray assembly 2 near the slide rail 62 via a rotating shaft, and the roller 63 is in rolling connection with the slide rail 62.

[0041] It should be noted that the spray assembly 2 is supported on the slide rail 62 by the roller 63. When the spray assembly 2 moves back and forth, the spray assembly 2 will cause the roller 63 to roll on the slide rail 62. Furthermore, through the cooperation between the roller 63 and the slide rail 62, the spray assembly 2 can also be guaranteed to perform linear movement.

[0042] It is known that the roller 63 is connected to the slide rail 62, which can significantly reduce the motion resistance between the two, making the reciprocating movement of the spray assembly 2 smoother. On the other hand, it can also reduce the load on the drive unit 5, improve energy efficiency, and avoid the spray assembly 2 from jamming or vibrating due to excessive friction, thus ensuring the continuity of liquid spraying.

[0043] Specifically, the drive unit 5 includes a drive motor 51, a rotating rod 52, an eccentric wheel 53, a rotating sleeve 54, and a support block 55. The drive motor 51, the rotating rod 52, and the support block 55 are connected sequentially from top to bottom. The eccentric wheel 53 is rotatably connected inside the rotating sleeve 54 and is fixed to the outside of the rotating rod 52. The rotating sleeve 54 is detachably connected to the spray assembly 2 through a connector 56.

[0044] It should be noted that the operation of the drive motor 51 can cause the rotating rod 52 to rotate. After the rotating rod 52 rotates, the eccentric wheel 53 will rotate synchronously. The eccentric wheel 53 will also rotate in the moving sleeve 54. The moving sleeve 54 is connected to the spray assembly 2 through the connecting piece 56. The spray assembly 2 makes linear motion on the bearing unit 6, which forms support and restriction on the moving sleeve 54. Therefore, after the eccentric wheel 53 rotates, the moving sleeve 54 will make reciprocating linear motion in the lateral direction. When the moving sleeve 54 makes reciprocating linear motion, the spray assembly 2 can make reciprocating motion on the bearing assembly.

[0045] It should also be noted that the number of eccentric wheels 53 corresponds to the number of spray assembly 2. After rotation, the two spray assembly 2 can be operated through the eccentric wheels 53. The two spray assembly 2 are arranged vertically and can also be connected to the corresponding rotating sleeve 54 through the connector 56.

[0046] In a specific embodiment, such as Figure 6-7 As shown, in this embodiment, a limiting plate 57 is provided on the top surface of the eccentric wheel 53. After the limiting plate 57 is connected to the eccentric wheel 53, it is used to limit the rotation sleeve 54 to ensure the connection stability.

[0047] Example 3:

[0048] The basic content is the same as in Example 1, except that:

[0049] Please see Figure 8 In this embodiment, a mounting bracket 7 is provided on the support plate 61, and a lubrication unit 8 is provided on the mounting bracket 7 corresponding to the roller 63. The lubrication unit 8 is used to reduce the friction between the roller 63 and the slide rail 62.

[0050] It should be noted that the lubrication unit 8 stores lubricating oil, which can discharge the lubricating oil onto the roller 63 and the slide rail 62. The lubricating oil forms a lubricating film on the contact surface of the roller 63 and the slide rail 62, which transforms the dry friction between metals into fluid friction or mixed friction, further reducing the coefficient of friction, thereby reducing the load on the drive unit 5 and reducing energy consumption. At the same time, it improves the response speed and operating efficiency of the reciprocating motion of the spray assembly 2. In addition, the lubricating oil can effectively isolate the direct contact between the surfaces of the roller 63 and the slide rail 62, reducing wear and micro-cracks caused by friction. Especially in high-frequency reciprocating motion, it extends the life of the roller 63 and the slide rail 62, reducing the frequency of component replacement and maintenance costs.

[0051] Specifically, the lubrication unit 8 includes a cylinder 81 and a ball bearing 82. The bottom surface of the cylinder 81 is provided with a connecting hole 83, and the ball bearing 82 is rotatably connected in the connecting hole 83. The top surface of the cylinder 81 is formed with an opening, and the cylinder 81 is connected to the cover 84 through the opening. The outer circumferential surface of the roller 63 is recessed with an arc-shaped groove 64, and the ball bearing 82 is rotatably connected in the arc-shaped groove 64. The size of the ball bearing 82 is adapted to the size of the arc-shaped groove 64.

[0052] It should be noted that the cylinder 81 stores lubricating oil, which is injected into the cylinder 81 through a removable cover plate. When the ball 82 rolls, it can discharge the lubricating oil from the cylinder 81. The inner wall of the connecting hole 83 is arc-shaped and matches the outer surface of the ball 82. The connecting hole 83 can limit the ball 82 and prevent it from being removed from the connecting hole 83.

[0053] During application, after the spray assembly 2 moves, the roller 63 will roll on the slide rail 62. When the roller 63 rolls, it can contact the ball bearing 82 through the arc groove 64 and drive the ball bearing 82 to rotate synchronously. After the ball bearing 82 rotates, it absorbs lubricating oil and transfers it to the roller 63. As the roller 63 continues to rotate, a small amount of lubricating oil is continuously discharged from the cylinder 81, thereby wetting the roller 63. Under the rotation of the roller 63, the lubricating oil can also be transferred to the slide rail 62 to lubricate the roller 63 and the slide rail 62.

[0054] It is known that the process of lubricating oil being discharged through the rotation of ball 82 depends on the dynamic sealing and fluid shearing action between ball 82 and connecting hole 83. When roller 63 rolls, its arc groove 64 drives ball 82 to rotate synchronously. The surface of ball 82 and the inner wall of connecting hole 83 form a micron-level gap (10-50um). Lubricating oil is adsorbed onto the surface of ball 82 under viscosity and generates centrifugal force as ball 82 rotates, spreading outward along the radial direction of ball 82. At the same time, the gap between ball 82 and the wall of connecting hole 83 forms a local negative pressure zone due to asymmetrical movement, which can continuously draw lubricating oil from the cylinder 81 into the gap. When ball 82 rotates, the geometric constraint of arc groove 64 causes lubricating oil to form a uniform oil film along the inner wall of arc groove 64, and the oil film is further spread to the entire arc groove 64 by the rotation of roller 63.

[0055] It should also be noted that the geometric matching between the arc groove 64 on the roller 63 and the slide rail 62 forms a physical constraint, ensuring that the roller 63 moves along a predetermined path, preventing the spray assembly 2 from shifting laterally or swaying during high-speed reciprocating motion, maintaining the consistency of the spray trajectory, and avoiding uneven liquid coverage caused by trajectory deviation. At the same time, the curved surface contact between the arc groove 64 and the slide rail 62 will also disperse the concentrated load into surface contact, reduce local stress, reduce wear on the roller 63 and the slide rail 62, and extend the service life of the components, which is especially suitable for high-frequency, long-cycle operation conditions.

[0056] In one specific embodiment, the mounting frame 7 is provided with a mounting groove 85, and the cylindrical body 81 is provided with a connecting groove 71 corresponding to the mounting groove 85. The cylindrical body 81 is detachably connected to the mounting frame 7 through the mounting groove 85 and the connecting groove 71. Under the action of the mounting groove 85 and the connecting groove 71, the cylindrical body 81 can be easily installed and removed from the mounting frame 7.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
