The voice coil is characterized in that the framework is a framework of the whole voice coil, the framework transmits a voice source driving force generated by the voice coil to the outside to form mechanical wave radiation diffusion, and therefore the voice coil framework is required to be light and high in rigidity, and the inner surface of the framework is required to be flat and smooth. In addition, since the voice coil is the main heat source in the speaker, its thermal energy rises as the speaker power rises, and burns out once the endurance limit is exceeded. Therefore, the voice coil is also required to have good high temperature resistance and heat dissipation. And the punching framework can lead hot air generated in the motion process of the voice coil to flow in the voice cavity, thereby reducing the temperature of the voice coil.
The production of the punching voice coil comprises the following main processes: firstly, sleeving a framework, then winding, adhering reinforcing paper, welding a nylon wire, finally demoulding, punching and carrying out inspection and test. At present, in the production of a punching voice coil, the die stripping and punching operation is usually set to two independent positions, manual operation is mostly adopted, the product quality is difficult to ensure on one hand, and the required operation time is long on the other hand.

One skilled in the relevant art will recognize, however, that the embodiments may be practiced without one or more of the specific details, or with other alternative and/or additional methods, materials, or components. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the invention. Similarly, for purposes of explanation, specific numbers, materials and configurations are set forth in order to provide a thorough understanding of the embodiments of the invention. However, the invention is not limited to these specific details. Further, it should be understood that the embodiments shown in the figures are illustrative representations and are not necessarily drawn to scale.
Reference in the specification to "one embodiment" or "the embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.
It should be noted that the embodiment of the present invention describes the process steps in a specific order, however, this is only for the purpose of illustrating the specific embodiment, and does not limit the sequence of the steps. Rather, in various embodiments of the present invention, the order of the steps may be adjusted according to process adjustments.
The present invention is based on the following insight of the inventors: in the production of the existing bobbin coil (also called bobbin voice coil), because the two processes of die stripping and punching are generally considered to be not related to each other, the two processes are performed separately at present, and two independent posts are usually required to be arranged, each post requires an operator, which requires more space and manpower resources. Meanwhile, the mold stripping operation is mostly manually operated by an operator at present. The force and consistency in the manual die stripping operation process are unstable, so that the product is easy to deform, the roundness size is seriously influenced, and the product performance is poor. Meanwhile, the product is blocked in the manual mold stripping process, an operator is difficult to strip the product, the mold stripping speed is further influenced, the operator is extremely easy to hurt, and the working efficiency is further reduced. In addition, although the punching operation is realized by a machine at present, the existing punching equipment has the following problems:
1. the safety control device is lacked, so that potential safety hazards exist, and the risk of injury to operators exists;
2. the residual paper scraps after punching have no fixed recovery device, and the post is messy;
3. the punching position is not accurate, the copper foil on the bonding pad is easy to punch, and the product is seriously scrapped; and
4. the lead wire is easy to break, and the product is scrapped.
The inventor finds the common point of the two procedures through research: firstly, in the production process of the framework coil, the die stripping and the punching are two adjacent procedures; secondly, punching is an operation directly performed on the skeleton coil after the demolding is completed, additional operations such as cooling, transferring and the like are not needed in the middle, and a conveying mechanism can be shared (such as a pushing device is shared to realize demolding and punching at the same time), so that if the punching is combined, the process is greatly simplified. However, through research, the inventor of the present invention has found that if the demolding and punching stations are considered to be combined together, that is, a punching device is disposed on the demolding station, and then an operator places the bobbin coil on the punching device to perform a punching operation after completing the demolding operation, such a process is not substantially improved in terms of efficiency and yield although the need for personnel and space can be reduced. The inventor finds that the main reason of low yield of the existing punching operation in the combined process is that a corresponding auxiliary mechanism is lacked, and the part to be punched is accurately positioned. Because the relative positions of the silk thread, the bonding pad and the part to be punched of the skeleton coil obtained in the previous process are standardized, namely the relative positions are basically fixed, in practice, the accuracy of the position to be punched can be ensured as long as the placing position and the angle of the skeleton coil are correct during punching operation, and therefore, the key for improving the punching yield is to ensure that the skeleton coil to be punched is placed at the correct position and angle. And aiming at the problems of yield and efficiency of the die stripping operation, a machine can be considered to replace the manual work, and further the stable control of the pressure during the die stripping and pressing can be realized. In addition, after the die stripping is finished, the punching operation can be performed without performing other operations on the framework coil, so that the die stripping and punching equipment can be integrated, the operation steps are further reduced, and the production efficiency is improved. In short, the invention not only simplifies the process by combining the working procedures, but also greatly improves the process precision by improving the positioning precision of the components.
Based on the above insights and studies, the present invention provides a framework coil demolding and punching device, and the following scheme of the present invention is further described with reference to the accompanying drawings of the embodiments.
Fig. 1 is a schematic structural diagram of a framework coil stripping and punching device according to an embodiment of the present invention. As shown in fig. 1, the die stripping and punching device for the bobbin coil integrates the die stripping and punching operations into a same device, and comprises a die stripping module and a punching module. The die stripping module is arranged above the punching module, so that the stripped framework coil can just enter the designated position of the punching module.
The demolding module comprises a demolding guide column 101 and a demolding pressing block 102. The die withdrawing guide post 101 is used for placing a framework coil to be withdrawn, and during operation, the framework coil to be withdrawn is sleeved on the die withdrawing guide post 101, so that the outer diameter of the die withdrawing guide post 101 needs to be set to be slightly smaller than the inner diameter of the framework coil to be withdrawn, but the outer diameter of the die withdrawing guide post 101 cannot be too small, the framework coil to be withdrawn is difficult to fix due to the fact that the outer diameter of the framework coil is too small, and further subsequent punching operation positioning is inaccurate; the die stripping pressing block 102 corresponds to the die stripping guide column 101 in the vertical direction, in order to ensure that the framework coil can be stripped from the die when the die stripping pressing block is pressed down, the die stripping pressing block 102 is of a hollow structure, and the inner diameter of the tail end of the die stripping pressing block is slightly larger than the outer diameter of the die stripping guide column 101 but smaller than the inner diameter of the framework coil to be stripped. In the present invention, the term "slightly smaller" or "slightly larger" means smaller or larger than by 10% or less of each other, for example, 1%, 5%, 6%, 7%, 8%, 10%, and the like. In the present invention, the term "anastomosis" means positional correspondence.
In order to ensure that the stripping press block 102 can be vertically pressed downwards, the framework coil to be stripped is uniformly stressed without losing the roundness, and the pressing distance of the stripping press block 102 is better controlled. In one embodiment of the present invention, the demolding module further comprises:
in order to ensure stability, in an embodiment of the present invention, a first support bar 1032 is disposed on the bottom plate, the first support bar 1032 is slidably connected to a first sleeve 1033 at the bottom of the first cross beam 103, and the first cross beam 103 is sleeved outside the first support bar 1032, so that the first cross beam 103 can move up and down along the first support bar 1032 under external force driving. In order to avoid the too large pressing depth of the demolding press block 102, in another embodiment of the present invention, a limiting device is further disposed on the bottom plate, and after the first beam 103 is pressed down to a certain distance, the first beam is blocked by the limiting device and cannot be pressed down further, the limiting device may be, for example, a bolt screwed to an upper bracket of a base, or a limiting block sleeved at the bottom of the first support rod 1032, and for example, the bolt may be screwed to adjust the height of the limiting device to meet the needs of different bobbin coils; and
the first beam 103 is connected to a driving module through a down-pressure rod 104, in one embodiment of the present invention, the driving module is a hydraulic driving unit, and the output pressure of the hydraulic driving unit is adjustable. In an embodiment of the present invention, in order to further ensure the uniformity of the stress, a second beam 105 is further disposed above the first beam 103, the second beam 105 is disposed parallel to the first beam 103, two ends of the bottom of the second beam 105 are respectively connected to the first beam 103 through second springs 1051, and the spring parameters, such as length and spring constant, of the two sides are the same, so as to ensure that the two ends of the second beam are stressed uniformly, and thus the two ends of the second beam are always kept horizontal. Meanwhile, the lower pressing rod 104 is connected to the bottom center position of the second beam 105, and the bottom of the second beam is connected to the driving module. In order to ensure stability, in an embodiment of the present invention, a second support rod 1052 is disposed at the bottom of the second beam 105, and a through hole is disposed at a position of the first beam 103 corresponding to the second support rod 1052, such that the second support rod 1052 can slidably connect with the first sleeve 1033 through the through hole, and the second spring 1051 is sleeved outside the second support rod 1052, and the second beam 103 can move up and down along the first support rod 1032 under the driving of an external force.
The punching module comprises a punching guide column 201 and a punching needle 202. The punching guide post 201 is sleeved at the lower end of the demolding guide post 101, the punching guide post 201 can be of a hollow structure, a plurality of through holes adaptive to the size of a punching needle are formed in the post wall of the punching guide post, and the framework coil is attached to the inner surface of the punching guide post after demolding. This can be achieved, for example, by: the inner diameter of the punching guide post is set to be slightly larger than or substantially equal to the size of the bobbin coil so that the bobbin coil can be stably fixed on the inner surface of the guide post by an elastic force. The punching needle 202 is arranged corresponding to the through hole and can reciprocate along the through hole under the driving of external force, so that the punching operation is completed on the framework coil through the through hole. In one embodiment of the invention, the punching needle is driven by a hydraulic driving unit, and as the die stripping and the punching are not performed synchronously, the punching needle and the die stripping press block can adopt the same hydraulic driving unit, and the hydraulic driving unit is controlled by a control center to sequentially output specified pressure according to an operation time sequence according to the pressure required by the die stripping and the punching.
In order to ensure that no obstacle exists in the operation area during the operation of the die stripping and punching device or both hands of an operator are timely withdrawn from the operation area after the operator places the framework coil to be stripped, in one embodiment of the invention, the die stripping and punching device further comprises a sensing unit 301 which can be connected with the driving module in a communication mode, and when the human hand or other obstacles exist in the operation area during the punching and stripping operation, the driving module is informed to stop working and alarm. The sensing unit can be infrared light curtain for example, infrared light curtain includes a plurality of infrared detector, set up in the both sides of module of punching a hole, during the start, can form infrared light curtain, in case someone's hand or other article appear in the light curtain, then send out the police dispatch newspaper, and control drive module stops work. The sensing unit can also be a proximity sensor, for example, and is arranged on the demolding guide column and/or the punching guide column, and once an obstacle such as a human hand is detected to approach the demolding guide column and/or the punching guide column, the driving module is informed to stop working, and an alarm is given. It should be understood that in other embodiments of the present invention, the sensing unit may also adopt other types of sensors, such as a distance sensor, etc., and the arrangement position thereof may be determined according to the need, and is not limited to the foregoing arrangement manner.
In order to ensure that the copper foil and/or the lead wire of the bonding pad are not damaged during punching operation, in one embodiment of the invention, the demolding punching device further comprises a positioning unit for positioning the framework coil. The positioning unit can perform positioning on the premise that the center line thereof is marked on the bobbin coil to be demoulded in the preceding operation. Based on this, the positioning unit can include, for example, an infrared emission unit, which is arranged on one side of the demolding guide post, so that infrared light emitted by the infrared emission unit points to a center line of the framework coil to be demolded when the framework coil to be demolded is correctly placed, and when an operator places the framework coil to be demolded, the infrared light is aligned with the center line of the framework coil. The positioning unit may further include a marking line disposed on the demolding guide post and/or the punching guide post, for example, and when an operator places a bobbin coil to be demolded, the operator aligns a center line of the bobbin coil with the marking line. It should be understood that in other embodiments of the present invention, the positioning unit is not limited to the foregoing two positioning manners, and may also include other manners, such as a scale.
Because the lead wire line of skeleton coil is longer, probably be drawn into in the guide post that punches a hole when the drawing die operation, even fall into and punch the needle and punch a hole within range, and then lead to being broken by punching when punching the operation. In order to avoid the situation, in an embodiment of the invention, a silk yarn limiting unit is further sleeved outside the demolding guide column, the silk yarn limiting unit comprises a film, a through hole is arranged in the middle of the film, the edge of the through hole is in a tooth shape, the diameter of the through hole is smaller than the inner diameter of the punching guide column but slightly larger than the outer diameter of the demolding guide column, so that the silk yarn can enter the punching guide column along with the framework coil when the demolding press block is pressed downwards, and the silk yarn can be erected along the direction opposite to the pressing direction of the framework coil due to the tooth shape of the through hole, so that the whole silk yarn is prevented from falling into the punching guide column.
During the punching operation, the punched paper scraps may remain inside the punching guide post, and when the paper scraps are too much, the punching guide post may be blocked, and thus the punching operation may fail or even the device may malfunction. To avoid this, in an embodiment of the present invention, the demolding punching device further includes a cleaning unit for periodically cleaning paper scraps left after punching, the cleaning unit includes an air pipe, which is communicated with the demolding press block and is driven by the cleaning driving module, and specifically, the air pipe is driven by the cleaning driving module to blow air while the demolding press block is pressed down. The cleaning driving module is started at regular time, in an embodiment of the present invention, the cleaning driving module is started according to the punching times, specifically, the driving module is started once after the punching operation is completed for a specified number of times, so the cleaning unit further includes a counter for counting the punching times, and the specified number of times is set as required.
