Description

TECHNICAL FIELD

[0001] The application relates to the technical field of stamping production, in particular to a high-density arrangement loudspeaker centering support stamping production process. BACKGROUND

[0002] The centering support is an important component of a loudspeaker system, also known as a dome and a positioning support, and can make a voice coil in a magnetic gap be in a correct position, reduce friction or collision of the voice coil with an upper clamping plate and a center column, and also play a certain dustproof role, so that dust and impurities are prevented from entering the magnetic gap and adversely affecting the performance of the loudspeaker.

[0003] In the production process of the centering support, the centering support needs to be punched, at present, laser cutting is usually used, and after punching by the laser cutting mode, carbonization and blackening can occur around the centering support, thereby affecting subsequent assembly and performance of the centering support. SUMMARY

[0004] In order to reduce the carbonization and blackening of the centering support after punching, the application provides a high-density arrangement loudspeaker centering support stamping production process.

[0005] The high-density arrangement loudspeaker centering support stamping production process provided by the application adopts the following technical scheme:

[0006] The high-density arrangement loudspeaker centering support stamping production process comprises the following steps:

[0007] S1: discharging: a plurality of centering supports are vertically stacked and placed on the top surface of the lifting frame;

[0008] S2: taking material: starting the material taking mechanism, the lifting driving assembly drives the first suction disc assembly and the second suction disc assembly to move downward until the first suction disc assembly and the second suction disc assembly respectively suck the two ends of the topmost centering support, and the taking of the centering support is completed;

[0009] S3: separating materials: after the first suction disc and the second suction disc suck the topmost centering support, the sucked centering support is separated from the remaining centering support stack;

[0010] S4: feeding: moving one end of the centering support to the top surface of the lower die;

[0011] S5: punching: after the centering support is placed on the top surface of the lower die, the upper die moves downward, the upper die abuts against the lower die, the centering support is punched by stamping, and the centering support is moved by the material moving mechanism, so that other parts of the centering support are sequentially punched;

[0012] S6: discharging: moving the punched centering support to the discharging frame for discharging.

[0013] By adopting the technical scheme, the first suction cup assembly and the second suction cup assembly sequentially suck the multiple centering vanes stacked on the top surface of the lifting frame, then move the sucked centering vanes to the top surface of the lower mold, press the upper mold and the lower mold to punch the centering vanes, and then the material moving mechanism discharges the punched centering vanes. Compared with the prior art, the carbonization and blackening of the centering vanes around the punching hole can be reduced, thereby reducing the impact on the subsequent assembly and performance of the centering vanes.

[0014] Preferably, in the material taking step, when the first suction cup assembly and the second suction cup assembly abut against the top surface of the topmost centering vane, the lifting frame moves downward by a corresponding distance synchronously during the continuous downward pressing of the first suction cup assembly and the second suction cup assembly, and the first suction cup assembly and the second suction cup assembly stop moving after the first suction cup assembly, the second suction cup assembly and the lifting frame stop moving, and then the first suction cup assembly and the second suction cup assembly suck the centering vane.

[0015] By adopting the technical scheme, the lifting frame moves downward synchronously during the continuous downward pressing of the first suction cup assembly and the second suction cup assembly, so that the action time of the first suction cup assembly and the second suction cup assembly on the centering vane can be prolonged, the impact force of the first suction cup assembly and the second suction cup assembly on the centering vane can be reduced, and the damage of the centering vane caused by the large impact force can be reduced, and at the same time, the damage of the first suction cup and the second suction cup can be reduced.

[0016] Preferably, in the material taking step, the four first suction cups in the first suction cup assembly suck two corners at one end of the centering vane, and the four second suction cups in the second suction cup assembly suck two corners at the other end of the centering vane, so that the centering vane is in a flat state.

[0017] By adopting the technical scheme, the four second suction cups in the second suction cup assembly suck two corners at the other end of the centering vane, so that the centering vane is sucked more stably, the falling of the centering vane is reduced, and the centering vane can be in a flat state, which facilitates the subsequent feeding of the centering vane into the lower mold for punching.

[0018] Preferably, in the material separation step, after the first suction cup assembly and the second suction cup assembly suck the topmost centering vane, the first suction cup assembly and the second suction cup assembly drive the sucked centering vane to move upward after "pointing" twice on the top surface of the centering vane stack, and then separate the sucked centering vane from the bottom centering vane stack.

[0019] By adopting the technical scheme, the stacked multiple centering vanes generate static friction force due to surface contact, which makes it difficult to separate the top sheet alone. When the first suction cup and the second suction cup suck the topmost centering vane flat, it is easier to move the subsequent centering vanes. The application separates the top centering vane from the bottom centering vane stack by "pointing" the top centering vane on the top surface of the bottom centering vane stack twice. When the bottom centering vanes are taken away at the same time, the centering vanes can be returned to the top surface of the bottom centering vane stack. At this time, the static friction generated between the sucked centering vanes and the taken away centering vanes has been destroyed. Therefore, by "pointing" the sucked centering vanes twice, the bottom centering vanes can be taken away at the same time when the sucked centering vanes are moved away from the bottom centering vane stack.

[0020] Preferably, in the punching step, after one end of the centering vane is punched, the conveying driving assembly is started to drive the conveying assembly to move the telescopic driving assembly to one end of the punch press. After the first moving suction cup is moved downward by the telescopic driving assembly and sucks one end of the centering vane, the telescopic driving assembly moves the first moving suction cup upward, and the conveying driving assembly moves the telescopic driving assembly away from the one end of the lower die to complete the movement of the centering vane.

[0021] By adopting the technical scheme, the punching of the whole centering vane is completed in several parts. After one part of the centering vane is punched, the conveying driving assembly and the telescopic driving assembly move the centering vane to punch the next part. Punching in multiple parts can improve the punching precision.

[0022] Preferably, the first moving suction cup has four, two of which suck one end of the centering vane, and the other two suck the other end along the wide edge of the centering vane.

[0023] By adopting the technical scheme, two first moving suction cups suck one end of the centering vane, and the other two first moving suction cups suck the other end along the wide edge of the centering vane, so that the movement of the centering vane is more stable, reducing the shaking of the centering vane during movement, and thus affecting the punching position.

[0024] Preferably, after the centering vane is moved, the next part of the centering vane that needs to be punched corresponds to the through hole, and then the first moving suction cup is pressed against the part of the centering vane that needs to be punched to fit the top surface of the lower die.

[0025] By adopting the technical scheme, the four first moving suction cups abut against the punching portions of the centering support sheet that need to be punched and the top surface of the lower die, thereby reducing the situation that the punching portions of the centering support sheet that need to be punched are not abutted against the lower die, and further reducing the situation that the centering support sheet is not abutted against the lower die and affects the punching quality.

[0026] Preferably, in the blanking step, after the centering support sheet is punched, the first moving suction cup assembly and the second moving suction cup respectively suck the two ends of the long side of the centering support sheet, and the first moving suction cup and the second moving suction cup suck the centering support sheet flat.

[0027] By adopting the technical scheme, the first moving suction cup assembly and the second moving suction cup respectively suck the two ends of the long side of the centering support sheet, thereby making the sucking of the centering support sheet more stable, and the first moving suction cup and the second moving suction cup suck the centering support sheet flat, facilitating subsequent blanking, and the blanked centering support sheet can be placed flat.

[0028] Preferably, in the blanking step, after the centering support sheet is sucked by the first moving suction cup and the second moving suction cup, the conveying driving assembly drives the telescopic driving assembly to move away from the end of the punch press until the centering support sheet is moved to the top of the blanking frame and placed in the blanking frame.

[0029] By adopting the technical scheme, after the centering support sheet is sucked by the first moving suction cup and the second moving suction cup, the centering support sheet is moved to the top of the blanking frame, and then the centering support sheet is placed in the blanking frame, and the blanking frame stores the centering support sheet.

[0030] Preferably, in the blanking step, after the centering support sheet is moved to the top of the blanking frame, the telescopic driving assembly is started again, and the telescopic driving assembly drives the first moving suction cup and the second moving suction cup to move downward, and after the centering support sheet is fed into the blanking frame, the centering support sheet is blanked.

[0031] By adopting the technical scheme, in the process of blanking the centering support sheet, the centering support sheet is fed into the blanking frame before blanking, thereby reducing the influence of the centering support sheet falling from a high position on the neatness of the stacked centering support sheets, and also reducing the damage of the centering support sheet during blanking.

[0032] In summary, the present application has at least one of the following beneficial technical effects:

[0033] 1、The application is through the first suction cup assembly and the second suction cup assembly to place in the lifting frame top surface stacked multiple centering vane in turn for suction, after the suction centering vane is moved to the lower die top surface, through the upper die and the lower die of the pressure, the centering vane is punched, and then the material moving mechanism is punched to the centering vane, compared with the prior art, through laser cutting, the carbonization and blackening of the centering vane punching around will appear, the application can reduce the carbonization and blackening of the centering vane after punching, so as to reduce the influence on the subsequent assembly and performance of the centering vane.

[0034] 2、Stacked multiple centering vane due to surface contact static friction, resulting in the top sheet is difficult to separate alone, the first suction cup and the second suction cup will be the top centering vane flat suction, more easy to produce the subsequent centering vane with the movement of the situation, the application through the step of separating the material, when the top centering vane and the bottom centering vane stack are separated, the top centering vane is "pointed" on the top surface of the bottom centering vane stack, when the bottom centering vane is taken away at the same time, the centering vane can be taken away again and sent back to the top surface of the bottom centering vane stack, at this time, the static friction between the suction centering vane and the taken away centering vane has been destroyed, therefore, after the suction centering vane is "pointed" twice, the suction centering vane is away from the bottom centering vane stack again, which can reduce the situation that the bottom centering vane is taken away at the same time.

DETAILED DESCRIPTION

[0039] The application is further described in detail below. Figures 1-3

[0040] ​​​The embodiment of the application discloses a high-density arrangement loudspeaker centering support sheet stamping production process.

[0041] Referring to Figure 1 A high-density arrangement loudspeaker centering support sheet stamping production process comprises the following steps: feeding, taking, material separation, feeding, punching and blanking.

[0042] Referring to Figure 1 And Figure 2 Feeding: a plurality of centering support sheets 6 are vertically stacked on the top surface of the lifting frame 1.

[0043] Specifically, the plurality of centering support sheets 6 are sequentially and neatly stacked along the vertical direction, so that the long edges of the plurality of centering support sheets 6 are in the same vertical plane after the plurality of centering support sheets 6 are stacked, and correspondingly, the wide edges of the plurality of centering support sheets 6 are in the same vertical plane. Then, the plurality of centering support sheets 6 that are stacked are placed on the top surface of the lifting frame 1, and the wide edges of the centering support sheets 6 are parallel to the wide edges of the lifting frame 1, the long edges of the centering support sheets 6 are parallel to the long edges of the lifting frame 1, and the centering support sheets 6 are located at the bottom of the output end of the taking mechanism 2, so that the feeding of the plurality of centering support sheets 6 is completed.

[0044] Taking: the taking mechanism 2 is started, the lifting driving assembly 21 drives the first suction disc assembly 23 and the second suction disc assembly 24 to move downward until the first suction disc assembly 23 and the second suction disc assembly 24 suck the two ends of the topmost centering support sheet 6, and the taking of the centering support sheet 6 is completed.

[0045] Specifically, the taking mechanism 2 is started, the lifting driving assembly 21 drives the mounting seat 22 to move downward, so as to drive the first suction disc assembly 23 and the second suction disc assembly 24 located at the bottom of the mounting seat 22 to move downward until the first suction disc assembly 23 and the second suction disc assembly 24 abut against the top surface of the centering support sheet 6. When the first suction disc assembly 23 and the second suction disc assembly 24 abut against the top surface of the topmost centering support sheet 6, the lifting frame 1 moves downward synchronously in the process that the first suction disc assembly 23 and the second suction disc assembly 24 continuously press downward, so as to prolong the action time of the first suction disc assembly 23 and the second suction disc assembly 24 on the centering support sheet 6, thereby reducing the impact force of the first suction disc assembly 23 and the second suction disc assembly 24 on the centering support sheet 6, and further reducing the damage of the centering support sheet 6 caused by the large impact force, and simultaneously, the damage of the first suction disc and the second suction disc can be reduced.

[0046] Referring to Figure 1 And Figure 2When the first suction cup assembly 23 and the second suction cup assembly 24 are synchronously moved downward by a corresponding distance, the first suction cup assembly 23 and the second suction cup assembly 24 stop moving with the lifting frame 1, and then the four first suction cups in the first suction cup assembly 23 respectively suck two corners at one end of the centering vane 6, and at the same time, the four second suction cups in the second suction cup assembly 24 respectively suck two corners at the other end of the centering vane 6, so that the four corners of the top surface of the topmost centering vane 6 are sucked, and the centering vane 6 is in a flat state, and the topmost centering vane 6 is completed.

[0047] Separation of the material: After the first suction cup and the second suction cup suck the topmost centering vane 6, the sucked centering vane 6 is separated from the remaining centering vane 6 stack.

[0048] Specifically, after the first suction cup and the second suction cup suck the topmost centering vane 6, the lifting driving assembly 21 drives the first suction cup and the second suction cup to move upward, so that the centering vane 6 sucked by the first suction cup and the second suction cup is separated from the bottom centering vane 6 stack. At this time, the first suction cup and the second suction cup move upward by a short distance, and then the lifting driving assembly 21 drives the first suction cup and the second suction cup to move downward, and the first suction cup and the second suction cup drive the sucked centering vane 6 to move downward, so that the sucked centering vane 6 abuts against the bottom centering vane 6 stack.

[0049] Referring to Figure 1 and Figure 2 Then, the above-mentioned up-and-down movement is repeated, and the number of repetitions is determined according to specific conditions. In the embodiment of the present application, the first suction cup and the second suction cup drive the centering vane 6 to move up and down twice. After completing the second downward movement, the lifting driving assembly 21 drives the first suction cup and the second suction cup to move upward again, and the first suction cup and the second suction cup drive the sucked centering vane 6 to move upward until the sucked centering vane 6 is higher than the horizontal plane of the operation platform.

[0050] That is, the first suction cup and the second suction cup drive the sucked centering vane 6 to “touch” the top surface of the centering vane 6 stack twice, and then drive the sucked centering vane 6 to move upward to separate the sucked centering vane 6 from the bottom centering vane 6 stack.

[0051] The stacked plurality of centering vanes 6 generates static friction due to surface contact, making it difficult to separate the top sheet alone. When the first and second suction cups evenly suck the topmost centering vane 6, it is easier to move the subsequent centering vanes 6 together. The present application separates the top centering vane 6 from the bottom centering vane 6 stack by "tapping" the top centering vane 6 twice on the top surface of the bottom centering vane 6 stack. When the bottom centering vane 6 is also moved, the centering vane 6 can be returned to the top surface of the bottom centering vane 6 stack. At this time, the static friction between the sucked centering vane 6 and the moved centering vane 6 has been destroyed, so that by "tapping" the sucked centering vane 6 twice, the sucked centering vane 6 can be moved away from the bottom centering vane 6 stack, reducing the likelihood of the bottom centering vane 6 being moved together.

[0052] Feeding: moving one end of the centering vane 6 to the top surface of the lower mold 32.

[0053] Specifically, after the first and second suction cups move the centering vane 6 to the side of the operation platform, the moving drive assembly 25 is started, the moving drive assembly 25 drives the lifting drive assembly 21 to move horizontally, so that the lifting drive assembly 21 drives the mounting seat 22 to move horizontally, and then drives the first and second suction cups that have sucked the centering vane 6 to move horizontally, until the centering vane 6 is moved to the top surface of the operation platform. When one end of the centering vane 6 is located on the top of the lower mold 32, the moving drive assembly 25 stops moving, the first and second suction cups release the suction of the centering vane 6, and the centering vane 6 is placed on the top surface of the workbench, and one end of the centering vane 6 is located on the top surface of the lower mold 32. Then, the moving drive assembly 25 is started again, the moving drive assembly 25 drives the lifting drive assembly 21 to return to the original position, completing the feeding of the centering vane 6.

[0054] Referring to Figure 1 and Figure 3 Punching: After the centering vane 6 is placed on the top surface of the lower mold 32, the upper mold 31 moves downward, and after the upper mold 31 and the lower mold 32 abut and press, the centering vane 6 is punched, and the centering vane 6 is moved by the material moving mechanism 4 to punch other parts of the centering vane 6 in turn.

[0055] Specifically, after the one end of the centering piece 6 is placed on the top surface of the lower die 32, the position of the centering piece 6 that needs to be punched corresponds to the through hole of the lower die 32 at this time, the punch 3 is started, the upper die 31 moves downward, the cutting column of the upper die 31 cuts the centering piece 6, and then the cutting column penetrates into the through hole after passing through the centering piece 6, thereby completing the punching of the one end of the centering piece 6. After that, the upper die 31 moves upward, the conveying driving assembly 41 is started again, the telescopic driving assembly 42 is driven by the conveying driving assembly 41 to move towards the one end of the punch 3, until the first moving suction cup assembly 43 is located on the top of the one end of the centering piece 6, the telescopic driving assembly 42 is started again, and the first moving suction cup assembly 43 is driven by the telescopic driving assembly 42 to move downward. After that, the four first moving suction cups suck the top surface of the one end of the centering piece 6, the telescopic driving assembly 42 is started again, and the first moving suction cup is driven by the telescopic driving assembly 42 to move upward. The first moving suction cup lifts the sucked one end of the centering piece 6, the conveying driving assembly 41 is started again, the telescopic driving assembly 42 is driven by the conveying driving assembly 41 to move away from the one end of the punch 3, thereby driving the first moving suction cup that sucks the one end of the centering piece 6 to move. After that, the first moving suction cup releases the suction of the centering piece 6, and the movement of the centering piece 6 is completed.

[0056] After the centering piece 6 is moved, the next part of the centering piece 6 that needs to be punched corresponds to the through hole, the conveying driving assembly 41 is started again, the telescopic driving assembly 42 is driven by the conveying driving assembly 41 to move towards the one end of the punch 3 again, until the four first moving suction cups are located on the top of the part of the centering piece 6 that needs to be punched, then the telescopic driving assembly 42 is started, and the first moving suction cup is driven by the telescopic driving assembly 42 to move downward. The four first moving suction cups abut against the top surface of the centering piece 6, the part of the centering piece 6 that needs to be punched is pressed against the top surface of the lower die 32, thereby reducing the situation that the part of the centering piece 6 that needs to be punched does not fit the lower die 32, and further reducing the situation that the centering piece 6 does not fit the lower die 32 and affects the punching quality.

[0057] Referring to Figure 1 and Figure 3 , after the first moving suction cup presses the centering piece 6 that needs to be punched, the telescopic driving assembly 42 drives the first moving suction cup to move upward, the conveying driving assembly 41 is started again, the telescopic driving assembly 42 is driven by the conveying driving assembly 41 to move away from the one end of the punch 3, until the first moving suction cup is away from the punch 3, and then the above punching steps are repeated until the punching of the whole centering piece 6 is completed.

[0058] Blanking: The centering piece 6 that has been punched is moved to the blanking frame 5 for blanking.

[0059] Specifically, when the punching of the whole centering piece 6 is completed, the conveying driving assembly 41 is started, the telescopic driving assembly 42 is driven by the conveying driving assembly 41 to move towards the end close to the punch 3, until the first moving suction cup is located on the top of one end of the centering piece 6, and the second moving suction cup is located on the top of the other end of the centering piece 6, then the telescopic driving assembly 42 is started, the first moving suction cup and the second moving suction cup are driven by the telescopic driving assembly 42 to move downwards, until the first moving suction cup and the second moving suction cup respectively suck the two ends of the long side of the centering piece 6, then the telescopic driving assembly 42 is started, the first moving suction cup and the second moving suction cup are driven by the telescopic driving assembly 42 to move upwards, the first moving suction cup and the second moving suction cup suck the centering piece 6 flat, then the conveying driving assembly 41 is started, the telescopic driving assembly 42 is driven by the conveying driving assembly 41 to move away from the end of the punch 3, until the centering piece 6 is moved to the top of the discharging frame 5, then the telescopic driving assembly 42 is started, the first moving suction cup and the second moving suction cup are driven by the telescopic driving assembly 42 to move downwards, then the first moving suction cup and the second moving suction cup release the suction of the centering piece 6, and the centering piece 6 is placed in the discharging frame 5.

[0060] The above are preferred embodiments of the present application, and the embodiments are only explanations of the present application, and do not limit the protection scope of the present application, therefore: equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
