Description

Technical Field

[0001] This invention relates to the field of reed surface treatment technology, and more specifically to a device for processing reeds for music boxes. Background Technology

[0002] The machining of the reeds (also known as comb teeth) in a music box is a core step in the manufacturing process, directly determining the sound quality, pitch, and lifespan of the music box. Therefore, the reed surface needs to be polished and then finely machined to remove any remaining debris and polishing fluid, reducing air friction noise and improving tonal purity. The surface treatment involves two core processes: mirror polishing and zero-residue cleaning. Currently, cleaning methods include solvent immersion.

[0003] According to CN114654368A, a surface polishing device for high-precision hardware parts production and processing includes a machine tool. A positioning mechanism is located in the center of the top of the machine tool. Mounting brackets are fixedly installed on the left and right sides of the top of the machine tool. A drive motor is fixedly installed on the top of the mounting brackets, and a drive shaft is fixedly sleeved at the other end of the output shaft of the drive motor. This invention utilizes a transmission block, limiting springs, and positioning springs. The transmission block facilitates the installation and fixing of multiple polishing discs by the operator, allowing for sequential use during polishing and progressively improving the polishing precision. The limiting and positioning springs, in conjunction with the active and driven toothed discs, allow the transmission block to rotate at a fixed angle, ensuring that each polishing disc rotates to its lowest point, achieving a horizontal top surface for polishing the surface of the workpiece.

[0004] However, in the aforementioned patent, polishing is mainly performed using polishing discs, ensuring that each disc can rotate to its lowest position. Since the reed has slits of varying lengths to produce different sound levels, during the polishing process of the upper and lower surfaces of the reed, the polishing discs completely cover the end faces of the reed, making it difficult for polishing debris to fly out. Instead, the debris accumulates and gets stuck in the slits. Furthermore, the polishing process creates micro-grooves on the reed surface, which also trap dust and other impurities. In subsequent coating processes, the accumulated debris affects the coating effect on the inner walls of the slits, and the debris covering the micro-grooves also results in insufficient coating, thus affecting the actual processing effect of the reed surface. Summary of the Invention

[0005] The purpose of this invention is to provide a device for processing the sound-producing reeds of a music box, in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a music box sound-producing reed processing device, located between a surface polishing station and a coating station, and further including a solvent pool for degreasing and oiling the reed, and a hanger for suspending the reed; A movable unit is vertically positioned above a solvent pool, which moves with a hanger and has a high position and a low position relative to the hanger. The movable unit includes a clamp that adaptively clamps a spring in the low position. The scraper, located on the movement path of the reed and used to scrape the surface of the reed, has its length direction aligned with that of the reed.

[0007] Preferably, a telescopic rod for driving the hanger is also included; A second slider is slidably disposed on the side of the solvent pool and used to drive the moving unit, and the second slider moves synchronously with the extension end of the telescopic rod.

[0008] Preferably, the speed ratio of the second slider to the extension end of the telescopic rod is 2:1.

[0009] Preferably, it also includes a rotating member disposed on the moving unit and used to drive the clamps toward the spring.

[0010] Preferably, the moving unit is provided with a drive motor for driving the clamp to rotate in the low position of the moving unit.

[0011] Preferably, the end face of the scraper is at least 2 cm above the surface of the solvent pool when the moving unit is in a low position.

[0012] Preferably, the scraper has a protrusion facing the spring sheet fixedly provided on its opposing surface, and the upper and lower surfaces of the protrusion are both inclined.

[0013] Preferably, it also includes an air outlet that is opened on the scraper and tilted downwards.

[0014] Preferably, a hot air blower is provided on the scraper.

[0015] Preferably, the clamp maintains a predetermined gap in its default state to guide the spring back to its original position as the moving unit moves from a high position to a low position. In the above technical solution, the music box reed processing device provided by the present invention has the following beneficial effects: The reed is immersed in a solvent pool by a hanger, further treating the surface of the reed, thereby fully cleaning the micro-grooves formed during the polishing process, degreasing and removing oil from the reed surface, reducing the amount of debris retained, and meeting the requirements of subsequent fine processing (such as coating). Furthermore, the clamps keep the reed in a vertical position, ensuring uniform spacing between the reeds and free flow of the solution, avoiding the problem of disordered stacking of the reeds due to buoyancy in the solvent pool.

[0019] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-12 As shown, a music box reed processing device is located between a surface polishing station and a coating station. It includes a solvent pool 1 for degreasing the reeds and a hanger 4 for suspending the reeds (e.g., a solvent pool 1 for degreasing the reeds). Figure 4 (as shown) The movable unit 5 is vertically disposed above the solvent pool 1. It moves with the hanger 4 and has a high position and a low position relative to the hanger 4. The movable unit 5 includes a clamp 52 that adaptively clamps the spring in the low position. The scraper 31, located on the movement trajectory of the reed and used to scrape the surface of the reed, has its length direction aligned with that of the reed.

[0021] Specifically, multiple hooks 41 are linearly arranged and rotatably mounted on the hanger 4. The springs are suspended on the hanger 4 through the hooks 41. The lower end of the hook 41 is a hook-shaped part. The workers hang the polished springs one by one onto the hooks 41, with the minimum spacing between the springs being greater than 5cm to prevent them from colliding with each other.

[0022] The moving unit 5 is slidably mounted on the side of the solvent tank 1 in a vertical direction, and the moving unit 5 can slide up and down relative to the hanger 4 (see below for details of the transmission method). The highest and lowest positions of the moving unit 5 relative to the hanger 4 during movement are respectively the high position and the low position. The moving unit 5 includes a crossbar 51 arranged along the length of the scraper 31, and a clamp 52 is mounted on the crossbar 51 (see below for details of the connection method). The lower end of the clamp 52 extends downward and passes through the scraper 31. In the default state, the hook 41 passes through the crossbar 51 and the scraper 31 sequentially from top to bottom (e.g., ...). Figure 5 (As shown). When the moving unit 5 is in a high position, the crossbar 51 and the clamp 52 are located at the upper end of the hook 41 and are far away from the hook-shaped part. At this time, the operator can manually suspend multiple springs on the hook 41 without the crossbar 51 and the clamp 52 interfering with the suspension process.

[0023] Then the drive bracket 4 moves downward, causing the bracket 4 to immerse the spring in the solvent pool 1 (e.g. Figure 6 As shown), the polished surface of the reed is thoroughly immersed in solvent to remove the debris generated during grinding. The solvent also washes away the micro-grooves formed during the polishing process, effectively removing residual grinding fluid and facilitating further surface processing of the reed. The moving unit 5 moves relative to the hanger 4 to a lower position, at which point the crossbar 51 and clamp 52 are both located below the hook 41 (as shown). Figure 6As shown, the crossbar 51 is located at the opening of the hook-shaped part to prevent the reed from detaching from the hook 41 due to the buoyancy of the solvent pool 1. When the reed is supported by buoyancy, it moves upward relative to the hook-shaped part. At this time, the reed and the hook 41 are not in direct contact, so that the solution in the solvent pool 1 can cover the point where the reed and the hook 41 were originally in contact. During the downward movement, the clamp 52 abuts against the upper end of the reed and finally clamps the reed. The clamp 52 restricts the reed so that it is immersed in the solvent pool 1 in a vertical state. However, if only the hook 41 is used to pull the reed into the solvent pool 1, the reed will form a disordered stack due to the buoyancy of the solvent pool 1, resulting in blind spots between the reeds and parts of the reed that have not been degreased. In this invention, the clamp 52 can avoid the above problems to a large extent, so that the solvent can flow evenly through the neatly arranged reeds.

[0024] Furthermore, a movable frame 3 is slidably provided along the edge of the solvent pool 1, and a scraper 31 is fixedly welded to the movable frame 3. The movable frame 3 is located directly below the moving unit 5. When the moving unit 5 moves down, it pushes the movable frame 3 to move down synchronously. After the reed is degreased, the drive hanger 4 moves the reed upward. During the upward movement, the moving unit 5 moves again relative to the hanger 4 to a higher position so that the clamp 52 moves up and releases the reed. The reed continues to be suspended by the hook 41 and is driven by the hook 41 to pass through the scraper 31 from bottom to top. The scraper 31 scrapes away the solvent liquid and the detached oil film on both sides of the reed, further playing the role of degreasing. Then, the worker removes the reed and sends it to the coating station, and manually lifts the movable frame 3 to reset it.

[0025] In the above technology, the reed is immersed in the solvent pool 1 by the hanger 4, which further treats the surface of the reed, thereby fully washing away the micro-grooves formed during the polishing process, degreasing and removing oil from the surface of the reed, reducing the amount of debris, and meeting the requirements of subsequent finishing operations (such as coating). Furthermore, the clamp 52 keeps the reed in a vertical position, ensuring uniform spacing between the reeds, free flow of the solution, and preventing disordered stacking of the reeds due to buoyancy in the solvent pool 1.

[0026] As a further embodiment of the present invention, it also includes a telescopic rod 11 for driving the hanger 4; The second slider 13 is slidably disposed on the side of the solvent pool 1 and used to drive the moving unit 5, and the second slider 13 moves synchronously with the extension end of the telescopic rod 11.

[0027] Specifically, the speed ratio of the second slider 13 to the extension end of the telescopic rod 11 is 2:1. The extension end of the telescopic rod 11 is fixedly provided with an assembly block 12, and the assembly block 12 is fixedly connected to the hanger 4 by bolt assembly. The second slider 13 is also fixedly connected to the moving unit 5 by bolt assembly.

[0028] A linear motor can be used to drive the second slider 13, so that the second slider 13 remains in the same direction as the end of the telescopic rod 11 and its moving speed is doubled (wherein the second slider 13 drives the moving unit 5 to move at a distance such as...). Figure 6 As shown in L2, the assembly block 12 drives the hanger 4 to move to form a shape as shown in the figure. Figure 6 (As shown in L1), or the following transmission method is adopted: the telescopic rod 11 is set on the side wall of the solvent pool 1, and a first slider 14 fixedly connected to the extension end of the telescopic rod 11 is slidably set on the side wall of the solvent pool 1. The second slider 13 is slidably set on the first slider 14. It also includes a first transmission belt 15 for driving the second slider 13. The first slider 14 is provided with two rollers for supporting the first transmission belt 15, and the first transmission belt 15 is divided into a front side and a rear side according to the line connecting the centers of the rollers. The front side of the first transmission belt 15 is fixed to the side of the solvent pool 1, and the second slider 13 is fixedly set on the rear side of the first transmission belt 15 (as shown in L1). Figure 3 (As shown).

[0029] When the extension end of the telescopic rod 11 moves the assembly block 12 downward, the assembly block 12 moves the hanger 4 downward, and at the same time, the extension end moves the first slider 14 downward. When the first slider 14 moves downward, it drives the first transmission belt 15 to rotate. The rear side of the first transmission belt 15 is restricted, while the front side will drive the second slider 13 to slide down twice the stroke of the first slider 14, thereby causing the moving unit 5 to move downward relative to the hanger 4. That is, in the initial state, the moving unit 5 is located at the upper end of the hook 41. At this time, the distance between the hook and the moving unit 5 is large, allowing the worker to easily suspend the spring. As the telescopic rod 11 moves the assembly block 12 downward, the hanger 4 moves the spring downward and immerses it in the solvent pool 1. At the same time, the moving unit 5 moves from a high position to a low position as the hanger 4 moves downward, and drives the clamp 52 to move downward and clamp the spring, keeping the spring in a vertical state.

[0030] As another embodiment of the present invention, it also includes a rotating member 53 disposed on the moving unit 5 and used to drive the clamp 52 toward the spring.

[0031] Specifically, the rotating component 53 is rotatably mounted on the crossbar 51. A cylinder 521 is fixedly mounted on the upper end of the clamp 52, and a spring is positioned between the two cylinders 521. The rotating component 53 has an arc groove 531 that slides with the cylinder 521. The arc groove 531 has a spirally opening structure. In the default state, the cylinder 521 is located at the end of the arc groove 531 near the circumference. Figure 9 With the indicated direction as a reference, the rotating part 53 is driven to rotate clockwise (see below for details of the driving method). The two cylinders 521 are squeezed by the arc groove 531 to drive the clamps 52 to move closer to each other. The spring contracts and the elasticity of the spring itself keeps the two cylinders 521 vertical.

[0032] As another embodiment of the present invention, the moving unit 5 is provided with a drive motor 55 for driving the clamp 52 to rotate in the low position state of the moving unit 5.

[0033] Specifically, the rotating parts 53 are arranged in a linear array on the crossbar 51, and a second transmission belt 54 is provided between adjacent rotating parts 53, so that the rotating parts 53 move synchronously in pairs. A pulley 57 for driving the end of the second transmission belt 54 is rotatably provided on the moving unit 5, and a third transmission belt 56 (e.g., ...) is provided between the output shaft of the drive motor 55 and the pulley 57. Figure 8 (As shown). The drive motor 55 has a built-in control module. According to the preset program, the drive motor 55 is started when the moving unit 5 approaches the surface of the solvent pool 1. The drive motor 55 drives multiple rotating parts 53 to rotate clockwise, so that the two clamps 52 move closer to each other and clamp the spring. Then the cylinder 521 reaches the end of the arc groove 531 near the center. The displacement of the cylinder 521 reaches its limit. The rotating parts 53 continue to rotate and drive the cylinder 521 to rotate. At this time, the clamps 52 clamp the spring and drive the spring to rotate. Multiple springs rotate at a constant speed in the solvent pool 1. At this time, the solvent in the solvent pool 1 is stirred by the springs to form a vortex, which improves the efficiency of the solvent in removing residual impurities from the surface of the springs. Conventional immersion methods simply involve placing a reed and then lifting it. However, the narrow gaps between the reeds can trap air within the gaps during immersion in the liquid. This air, under the influence of solvent tension, forms bubbles within the gaps, preventing sufficient immersion. Furthermore, these gaps are prone to trapping debris and grinding fluid, necessitating further surface treatment. In this invention, the rotation of the reeds guides the solvent through the gaps between them, allowing the flowing solvent to carry away air bubbles and impurities trapped in the gaps, thus significantly improving the processing efficiency of the reeds.

[0034] As another embodiment of the present invention, the scraper 31 has a protrusion facing the spring sheet fixedly provided on the facing surface, and the upper and lower surfaces of the protrusion are both inclined.

[0035] Specifically, the protruding parts are as follows Figure 11 As shown, the raised portion arches towards the center, and this raised portion can be made of a flexible material with a certain degree of elasticity to adapt to the structure of the spring. The portion of the raised portion facing the spring can be covered with a soft material such as sponge to reduce the scraping force on the spring. During the downward movement of the moving unit 5 relative to the hanger 4, it pushes the movable frame 3 downward, at which point the scraper 31 remains above the spring. When the hanger 4 moves the spring upward, the spring passes through the scraper 31 from bottom to top. At this time, the solvent and grease on the surface of the spring are scraped away by the raised portion, achieving a more thorough cleaning effect.

[0036] As another embodiment of the present invention, it also includes an air outlet 312 that is opened on the scraper 31 and tilted downward.

[0037] Specifically, the inner diameter of the air outlet 312 decreases along the air outlet direction, and the air outlet 312 is as follows: Figure 11 Multiple micro-pores are shown. During the downward movement of the moving unit 5 relative to the hanger 4, it pushes the movable frame 3 downward. When the moving unit 5 reaches its lowest position, the movable frame 3 and the scraper 31 are at least 2 cm above the surface of the solvent pool 1. During immersion, the reed undergoes degreasing and oil removal. These impurities float on the surface of the solvent pool 1, accumulating to form a thin oil film that covers the solvent surface. During the reed lifting process, this oil film may re-adhere to the reed surface under surface tension. In this invention, the air outlet 312 emits air downwards, and the inclined airflow on both sides generates a component force on the liquid surface, forming a horizontal airflow (e.g., below the scraper 31) towards the central axis of the scraper 31. Figure 12 As shown in Figure a), the floating impurities on the surface are guided by the airflow and accumulate directly below the scraper 31. The shearing force of the airflow in the horizontal direction "pulls" the impurities, tearing the continuous oil film and making it difficult for the oil film to form a continuous interface, thus inhibiting its spreading ability. When the reed moves upward, the upper end of the reed cuts and breaks up the previously accumulated impurities. At this time, as the reed extends out of the liquid surface, the airflow at the surface outlet 312 moves downward along the reed surface and is guided to the liquid surface, forming a boundary layer airflow on the reed surface (such as...). Figure 12 As shown in Figure b), the airflow moves downwards and pushes the oil away from the reed at the liquid surface; finally, the reed moves upwards to the protruding part of the scraper 31, where the protruding part, combined with the air outlet 312, further dries and removes impurities from the surface of the reed (as shown in Figure b). Figure 12 (As shown in Figure c).

[0038] Furthermore, an oil collection trough 16 is provided at the edge of the solvent pool 1 (the setting of the oil collection trough 16 is common knowledge to those skilled in the art and will not be described in detail here). After the reed is immersed, it is driven to rotate by the clamp 52. At this time, multiple reeds are equivalent to stirring blades rotating in the solvent pool 1, and the centrifugal effect generated by the eddy current pushes the impurities to the edge of the solvent pool 1, that is, the oil collection trough 16, to achieve the effect of removing impurities.

[0039] As another embodiment of the present invention, a hot air blower 32 is provided on the scraper 31.

[0040] Specifically, the hot air blower 32 has a built-in heating unit to convert outside air into high-speed hot air, which dries the side of the reed while blowing air to remove impurities. The scraper 31 has an air passage 311 for supplying air to the air outlet 312 (e.g., Figure 11 As shown in the figure, the airflow velocity provided by the hot air blower 32 is 8 to 9.6 m / s.

[0041] As another embodiment of the present invention, the clamp 52 maintains a predetermined gap in the default state to guide the spring back to the correct position during the movement of the moving unit 5 from the high position to the low position.

[0042] Specifically, during the process of immersing the reed in the solvent pool 1, the reed is first suspended by the hook 41. As the volume of the reed increases in the solvent pool 1, the buoyancy gradually increases, causing the reed to no longer maintain its original vertical state. At this time, the clamp 52 moves down with the moving unit 5. The gap of the clamp 52 is greater than the width of the reed. During the downward movement, the clamp 52 will push against the tilted reed and make the reed slightly return to its upright position. Then, the clamps 52 move closer together and clamp the reed, making the reed completely return to its upright position. During this process, the reed has a tilting and then returning to its upright position, which is equivalent to the reed making a slight swing, further dislodging the air bubbles present in the gap.

[0043] Working principle: When the extension end of the telescopic rod 11 moves the assembly block 12 downward, the assembly block 12 moves the hanger 4 downward. At the same time, the extension end moves the first slider 14 downward. When the first slider 14 moves downward, it drives the first transmission belt 15 to rotate. The rear side of the first transmission belt 15 is restricted, while the front side will drive the second slider 13 to slide down twice the stroke of the first slider 14, thereby causing the moving unit 5 to move downward relative to the hanger 4. That is, in the initial state, the moving unit 5 is located at the upper end of the hook 41. At this time, the distance between the hook and the moving unit 5 is large, allowing the worker to easily suspend the spring. As the telescopic rod 11 moves the assembly block 12 downward, the hanger 4 moves the spring downward and immerses it in the solvent pool 1.

[0044] When the moving unit 5 approaches the surface of the solvent pool 1, the drive motor 55 is activated. The drive motor 55 drives multiple rotating parts 53 to rotate clockwise, thereby causing the two clamps 52 to approach each other and clamp the spring. Then the cylinder 521 reaches the end of the arc groove 531 near the center. The displacement of the cylinder 521 reaches its limit. After the rotating parts 53 continue to rotate, they drive the cylinder 521 to rotate.

[0045] The movable frame 3 is located directly below the moving unit 5. When the moving unit 5 moves downward, it pushes the movable frame 3 downward simultaneously. When the moving unit 5 reaches its lowest position, the movable frame 3 and the scraper 31 are located at least 2 cm above the liquid surface of the solvent pool 1. The air outlet 312 discharges air downward, and the inclined airflow on both sides splits at the liquid surface to form a horizontal airflow below the scraper 31 towards the central axis of the scraper 31 (e.g., Figure 12As shown in Figure a), the floating impurities on the surface are guided by the airflow and accumulate directly below the scraper 31. The shearing force of the airflow in the horizontal direction "pulls" the impurities, tearing the continuous oil film and making it difficult for the oil film to form a continuous interface, thus inhibiting its spreading ability. When the reed moves upward, the upper end of the reed cuts and breaks up the previously accumulated impurities. At this time, as the reed extends out of the liquid surface, the airflow at the surface outlet 312 moves downward along the reed surface and is guided to the liquid surface, forming a boundary layer airflow on the reed surface (such as...). Figure 12 As shown in Figure b), the airflow moves downwards and pushes the oil away from the reed at the liquid surface; finally, the reed moves upwards to the protruding part of the scraper 31, where the protruding part, combined with the air outlet 312, further dries and removes impurities from the surface of the reed (as shown in Figure b). Figure 12 (As shown in Figure c).

[0046] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
