Description

Technical Field

[0001] This application relates to the field of audio equipment manufacturing technology, and in particular to an audio cone processing production line. Background Technology

[0002] A speaker, also known as a loudspeaker, is composed of various parts, one of which is the paper cone.

[0003] The paper cone, also known as the speaker cone, is an important component of a loudspeaker. When an audio signal is applied to the voice coil, it vibrates violently in a magnetic field. The voice coil is fixed to the paper cone, and the vibration of the voice coil simultaneously drives the vibration of the paper cone. The vibration of the paper cone forces the air to vibrate, thereby producing sound.

[0004] During the manufacturing process, speaker cones are formed using molds. When formed, the cone is shaped like a frustum, with a folded ring at the bottom and a conical wavy opening at the top, and a conical surface in the middle. Grease adheres to the surface of the cone. When bonding it to the speaker, the presence of grease can cause the bonding to be weak, so the grease on the cone needs to be removed. Generally, the grease is removed manually, which is inefficient and has high labor costs. Summary of the Invention

[0005] To address the aforementioned problems, this application provides a speaker cone processing production line.

[0006] The audio cone processing production line provided in this application adopts the following technical solution:

[0007] A speaker cone processing production line includes a conveying device, placement components, and a laser folding and degreasing mechanism. The conveying device is equipped with several placement components for placing the speaker cones, and the placement components are detachably connected to the conveying device. The placement components are sequentially transported along the conveying path of the conveying device, which operates intermittently. The laser folding and degreasing mechanism is located on the conveying path of the conveying device. When the conveying device intermittently transports the placement components to the laser folding and degreasing mechanism, the laser end of the laser folding and degreasing mechanism moves along the speaker cone and degreases the surface of the speaker cone.

[0008] By adopting the above technical solution, when the transmission equipment intermittently transmits the placement part to the laser folding and degreasing mechanism, the laser end of the laser folding and degreasing mechanism moves to the paper basin to fold the paper basin surface. The laser end generates photothermal heat, and when it moves along the folding surface, it can remove the grease on the folding surface, thereby achieving the effect of automatically removing the grease from the paper basin.

[0009] Optionally, the transmission path of the transmission device is further provided with a laser wave oil removal mechanism; the laser wave oil removal mechanism is located behind the laser folding ring oil removal mechanism.

[0010] By adopting the above technical solution, the laser wave degreasing mechanism is set behind the laser folding degreasing mechanism, so that after the paper basin is degreased by the laser folding degreasing mechanism, the transmission equipment intermittently travels a preset distance, and the laser wave degreasing mechanism turns on the laser at the conical wave opening of the paper basin to generate photothermal effect to provide degreasing.

[0011] Optionally, the transmission path of the transmission device is further provided with an acetone degreasing mechanism; the acetone degreasing mechanism is located behind the laser wave degreasing mechanism.

[0012] By adopting the above technical solution, in order to avoid grease residue after laser degreasing, an acetone degreasing mechanism is set after the laser wave degreasing mechanism. According to the properties of acetone, acetone is applied to the paper basin so that the residual grease on the surface of the paper basin is removed by acetone, thereby further improving the thoroughness of degreasing.

[0013] Optionally, a protective layer forming mechanism is also provided on the transmission path of the transmission device; the protective layer forming mechanism has a built-in treatment agent and is located behind the acetone degreasing mechanism.

[0014] By adopting the above technical solution, the treatment agent is applied to the surface of the paper basin using the protective layer forming mechanism, which enables the treatment agent to contact the surface of the paper basin more stably and corrode or penetrate the surface of the paper basin to form a stable protective layer.

[0015] Optionally, the placement component includes a placement seat and a fixing part; the placement seat is in the shape of a rectangular plate and is located on the transmission path of the transmission device, and the fixing part is located at the center of the placement seat and has a protruding protrusion in the vertical direction.

[0016] By adopting the above technical solution, the placement seat is rectangular plate-shaped, which is convenient to confine within the transmission equipment, avoids transmission position deviation, and is also convenient to take out or put in. The fixing part and the ejector protrusion can be adapted to the conical wave mouth of the paper basin. The ejector protrusion pushes out in the direction of the conical wave mouth to limit the position of the paper basin and prevent the paper basin from shifting position during the conveying process.

[0017] Optionally, the placement base is further provided with a positioning part, and a plurality of positioning parts are provided, which are respectively located around the placement base.

[0018] By adopting the above technical solution, the fixing part can be embedded in several positioning parts to achieve the limiting function, further providing stable limiting for the paper tray, and ensuring accurate conveying position during conveying and degreasing processes.

[0019] Optionally, the transmission device is provided with a turning point, and the turning point is further provided with a conversion mechanism to convert the travel path of the placement component.

[0020] By adopting the above technical solution and setting a conversion mechanism at the turning point, the position and travel path of the placed item can be changed, while preventing the placed item from being pushed out of the transmission equipment by other placed items that are continuously being transmitted from behind.

[0021] Optionally, the conversion time of the conversion mechanism is during the interval of the transmission device.

[0022] By adopting the above technical solution, the conversion time of the conversion mechanism is within the interval, so that the transmission equipment will not transmit the next placement item to move, thus avoiding interference with the conversion mechanism.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the transmission equipment intermittently transmits the placed part to the laser folding and degreasing mechanism, the laser end of the laser folding and degreasing mechanism moves to the paper basin to fold the paper basin surface. The laser end generates photothermal heat, and when it moves along the folding surface, it can remove the grease on the folding surface, thereby achieving the effect of automatically removing the grease from the paper basin.

[0025] 2. The laser wave degreasing mechanism is set behind the laser folding degreasing mechanism, so that after the paper basin is degreased by the laser folding degreasing mechanism, the transmission equipment intermittently travels a preset distance, and the laser wave degreasing mechanism turns on the laser at the conical wave opening of the paper basin to generate photothermal effect to provide degreasing.

[0026] 3. To avoid grease residue after laser degreasing, an acetone degreasing mechanism is installed after the laser wave degreasing mechanism. Based on the properties of acetone, acetone is applied to the paper basin to remove the residual grease on the surface of the paper basin, thereby further improving the thoroughness of degreasing.

[0027] 4. By using a protective layer forming mechanism to apply the treatment agent to the surface of the paper basin, the treatment agent can be more stably contacted with the surface of the paper basin and corrode or penetrate the surface of the paper basin to form a stable protective layer.

[0037] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0038] This application discloses a production line for processing speaker cones.

[0039] A production line for processing audio paper cones, in which the paper cones are manufactured and formed using molds. During the forming process, the paper cones are shaped into frustum cones, forming a bottom folded ring and a top conical wave opening, with a conical surface in the middle. The specific dimensions are determined according to the requirements.

[0040] refer to Figure 1 and Figure 2 As shown, it includes a transmission device 1, placement components 2, and a laser folding ring degreasing mechanism 3; the transmission device 1 is provided with several placement components 2 for placing paper basins, the transmission device 1 can be a conveyor belt, and the transmission path can be U-shaped to extend the degreasing path, so that the transmission device 1 can support more placement components 2.

[0041] The placement component 2 moves sequentially along the transmission path of the transmission device 1, and the transmission device 1 is an intermittent conveyor. Intermittent conveying means that after conveying a certain distance, it stops for a preset time, such as 5s or 10s, and then continues to convey. This conveying method can reserve enough time for the work of other mechanisms. The placement component 2 and the transmission device 1 are detachably connected. The detachable connection can be a placement abutment, where the placement component 2 is placed on the transmission device 1. When it needs to be disassembled, the placement component 2 can be taken out of the transmission device 1. The detachable connection method makes it easy to replace the placement component 2 to adapt to the removal of grease from paper basins of different sizes.

[0042] The laser degreasing mechanism 3 is located on the transmission path of the transmission device 1. The laser degreasing mechanism 3 can perform laser degreasing on the folds of the paper cone. The folds of the paper cone are the main parts that come into contact with the speaker. When connecting, adhesive needs to be applied to the surface of the folds of the paper cone. However, if there is grease on the surface of the folds, the bonding effect will be reduced, or even cause the paper cone and the speaker to fall off and separate, affecting the quality of the speaker. Therefore, when the paper cone is transported to the laser degreasing mechanism 3 along the transmission device 1 through the placement part 2, the folds of the paper cone can be degreased by the laser degreasing mechanism 3.

[0043] The laser folding ring degreasing mechanism 3 may include a laser end and a driving end. The laser end is the laser emitting end, which can emit laser light to generate photothermal effect, thereby removing oil. The driving end can drive the laser end to rise and fall to the folding ring on the surface of the paper basin. The driving end includes a driving structure for the X, Y and Z axes. The driving structure is a driving element such as an electric push rod or a cylinder. The laser end moves along the surface of the folding ring of the paper basin during the driving process of the driving end to remove oil.

[0044] Specifically, when the transmission device 1 intermittently transmits the placement piece 2 to the laser folding ring degreasing mechanism 3, the laser end of the laser folding ring degreasing mechanism 3 moves to the paper basin to fold the surface of the paper basin. The laser end generates photothermal energy, and when it moves along the folding ring surface, it can remove the grease on the folding ring surface, thereby achieving the effect of automatically removing the grease from the paper basin. At the same time, when the laser degreases the folding ring of the paper basin, the laser can also roughen the folding ring surface, making the folding ring surface no longer smooth and making it easier for the adhesive to adhere to the folding ring.

[0045] The transmission device 1 may also be equipped with a positioning sensor to check whether the moving position of the placement component 2 is accurate.

[0046] In some embodiments, reference Figure 1 and Figure 2 As shown, the transmission path of the transmission device 1 is also equipped with a laser wave degreasing mechanism 4. The structure of the laser wave degreasing mechanism 4 is similar to that of the laser folding ring mechanism, both including a laser end and a driving end. The difference lies in the path of the driving end. The path and distance of the driving end are controlled by the background programming. The laser end performs laser degreasing on the top of the paper basin and the conical wave opening according to the path driven by the driving end.

[0047] The conical spout of the paper cone needs to be bonded to the voice coil of the speaker. To avoid grease buildup at the conical spout, the laser spout degreasing mechanism 4 is positioned behind the laser folding degreasing mechanism 3. This allows the paper cone to be degreased by the laser folding degreasing mechanism 3, and the transmission device 1 to travel a preset distance intermittently. The laser spout degreasing mechanism 4 then activates the laser at the conical spout of the paper cone to generate photothermal effect and remove grease.

[0048] In some embodiments, reference Figure 1 and Figure 2 As shown, the transmission path of the transmission device 1 is also equipped with an acetone degreasing mechanism 5; the acetone degreasing mechanism 5 is located behind the laser wave degreasing mechanism 4. Acetone is an organic solvent that can be used for degreasing. Because acetone has low polarity, according to the principle of like dissolves like, non-polar substances are more easily dissolved by non-polar acetone. Therefore, the degreasing speed is fast and it does not corrode metals and other materials.

[0049] The acetone degreasing mechanism 5 may include a spraying end, a driving end, and a liquid storage end. The spraying end is a smear head, and a liquid delivery tube is connected inside the smear head so that acetone can be delivered to the smear head. The driving end includes a driving structure for the X, Y, and Z axes. The driving structure, such as an electric push rod or a cylinder, can drive the spraying end to move along the X, Y, and Z axes, that is, to move forward and backward, to move left and right, and to move up and down. The liquid storage end is a storage cylinder for storing acetone and may be equipped with a delivery pump to provide sufficient delivery pressure to deliver acetone to the spraying end.

[0050] Specifically, after laser degreasing, in order to avoid grease residue, an acetone degreasing mechanism 5 is set after the laser wave degreasing mechanism 4. According to the properties of acetone, acetone is applied to the paper basin so that the residual grease on the surface of the paper basin is removed by acetone, further improving the thoroughness of degreasing.

[0051] In some embodiments, reference Figure 1 and Figure 2 As shown, a protective layer forming mechanism 6 is also provided on the transmission path of the transmission device 1. The structure of the protective layer forming mechanism 6 is similar to that of the acetone degreasing mechanism 5, both including a spraying end, a driving end, and a liquid storage end. The difference is that the liquid stored in the liquid storage end is a treatment agent, such as 6303 treatment agent. The treatment agent is applied to the surface of the paper basin, such as the surface of the folding ring and the conical corrugated nozzle, through the spraying end. The treatment agent can penetrate into the paper basin and form a protective film. The protective film formed by the treatment agent comes into contact with the adhesive, making the adhesion more stable and the connection stronger.

[0052] The protective layer forming mechanism 6 is located behind the acetone degreasing mechanism 5. After multiple layers of degreasing using laser degreasing and acetone degreasing, there is no more grease on the surface of the paper basin. At this time, the protective layer forming mechanism 6 is used to apply the treatment agent to the surface of the paper basin, which enables the treatment agent to contact the surface of the paper basin more stably and corrode or penetrate the surface of the paper basin to form a stable protective layer.

[0053] In some embodiments, reference Figure 3 As shown, the placement component 2 includes a placement seat 21 and a fixing part 22; the placement seat 21 is in the shape of a rectangular plate and is located on the transmission path of the transmission device 1. The rectangular plate shape of the placement seat 21 makes it easy to confine within the transmission device 1, avoid transmission position deviation, and also makes it easy to take out or put in.

[0054] Several placement seats 21 can be placed consecutively along the transmission path, and adjacent placement seats 21 can contact each other, so that the degreasing mechanism can match the placement seat 21 each time it travels. The fixing part 22 can be a placement plate, which is located at the center of the placement seat 21 and has a push-out protrusion 221 in the vertical direction. The push-out protrusion 221 can be rod-shaped, and the style of the rod-shaped push-out protrusion 221 is adapted to the conical aperture of the paper basin. The push-out protrusion 221 pushes out in the direction of the conical aperture to limit the position of the paper basin and prevent the paper basin from shifting during the conveying process.

[0055] Further reference Figure 3As shown, the placement seat 21 is also provided with a positioning part 23. Several positioning parts 23 are provided and are located around the placement seat 21. The paper tray is placed in the positioning part 23. The positioning part 23 can be a bending block. The bending block has a bending groove. The corner of the fixing part 22 can be placed in the bending groove to achieve the limiting function, and further provide stable limiting for the paper tray, so as to ensure accurate conveying position during conveying and degreasing.

[0056] In some embodiments, the transmission device 1 is provided with a bend, which can be adapted to different degreasing environments, such as site limitations. The bend can reduce the horizontal setting length. A conversion mechanism 7 is also provided at the bend, which can convert the position and travel path of the placement component 2 so that the placement component 2 will not be pushed out of the transmission device 1 by other placement components 2 continuously being transmitted from behind.

[0057] Further reference Figure 2 and Figure 3 As shown, the conversion mechanism 7 includes a lifting drive unit and a conversion push unit; the lifting drive unit is located below the transmission device 1 and has a lifting end that penetrates the transmission device 1. The lifting drive unit can be a lifting electric push rod or a lifting cylinder, and the lifting end can be a lifting seat. The lifting seat is connected to the lifting electric push rod or the lifting cylinder, so that the lifting seat can be driven by the lifting electric push rod or the lifting cylinder to rise and fall.

[0058] The conversion push unit is connected above the transmission device 1 and is level with the height of the lifting end after it is lifted. The conversion push unit can be an electric push rod or a cylinder. The conversion push unit can push the lifted placement piece 2 in the direction after turning, thereby ensuring the stability of the conversion.

[0059] The conversion time is within the interval, that is, the lifting and pushing are within the interval. Therefore, during the lifting and pushing process, the transmission device 1 will not transmit the movement of the next placement piece 2.

[0060] In some embodiments, reference Figure 2 As shown, a blowing and exhaust system is also provided above the transmission device 1 to prevent the treatment agent from burning.

[0061] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
