Description

Technical Field

[0001] The present application relates to the technical field of stamping production, and particularly relates to a stamping production process for a high-density arrangement of speaker centering supports. Background Art

[0002] The centering support is an important component of the speaker system, also known as the spider and positioning support. The centering support can keep the voice coil in the correct position in the magnetic gap, reduce the friction or collision between the voice coil and the upper clamping plate and the center post, and at the same time play a certain dust-proof role, reducing the entry of dust and other impurities into the magnetic gap and avoiding adverse effects on the performance of the speaker.

[0003] During the production process of the centering support, it is necessary to punch holes in the centering support. At present, laser cutting is often used. After punching holes by laser cutting, carbonization and blackening will occur around the punched holes of the centering support, which will affect the subsequent assembly and performance of the centering support. Summary of the Invention

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

[0005] A stamping production process for a high-density arrangement of speaker centering supports provided by the present application adopts the following technical solutions: A stamping production process for a high-density arrangement of speaker centering supports includes: S1: Feeding: Vertically stack multiple centering supports on the top surface of the lifting frame; S2: Material taking: Start the material taking mechanism, and the lifting drive assembly drives the first suction cup assembly and the second suction cup assembly to move downward until the first suction cup assembly and the second suction cup assembly respectively suck the two ends of the topmost centering support to complete the material taking of the centering support; S3: Material separation: After the first suction cup and the second suction cup suck the top centering support, separate the sucked centering support from the remaining stack of centering supports; S4: Feeding: Transfer one end of the centering support to the top surface of the lower die; S5: Punching: After the centering support is placed on the top surface of the lower die, the upper die moves downward. After the upper die and the lower die are pressed against each other, punch holes in the centering support, and move the centering support through the material moving mechanism to punch the other parts of the centering support in sequence; S6: Discharging: Transfer the punched centering support to the discharging frame for discharging.

[0006] By adopting the above technical solution, the present application successively sucks a plurality of centering support pieces stacked on the top surface of the lifting frame through the first suction cup assembly and the second suction cup assembly. Then, the sucked centering support pieces are moved to the top surface of the lower die. Through the pressing of the upper die and the lower die, holes are punched in the centering support pieces. Then, the material transfer mechanism discharges the centering support pieces that have completed the hole punching. Compared with the prior art where holes are punched by laser cutting, carbonization and blackening will occur around the holes punched in the centering support pieces. The present application can reduce the carbonization and blackening of the centering support pieces after hole punching, thereby reducing the impact on the subsequent assembly and performance of the centering support pieces.

[0007] Preferably, in the processing step of material taking, when the first suction cup assembly and the second suction cup assembly are in contact with the top surface of the topmost centering support piece, during the continuous downward pressing process of the first suction cup assembly and the second suction cup assembly, the lifting frame moves downward by a corresponding distance synchronously. After the first suction cup assembly, the second suction cup assembly and the lifting frame stop moving, the first suction cup assembly and the second suction cup assembly suck the centering support piece.

[0008] By adopting the above technical solution, during the continuous downward pressing process of the first suction cup assembly and the second suction cup assembly, the lifting frame moves downward synchronously, so that the acting time of the first suction cup assembly and the second suction cup assembly on the centering support piece can be extended, thereby reducing the impact force of the first suction cup assembly and the second suction cup assembly on the centering support piece, and further reducing the situation that the centering support piece is damaged by a large impact force. At the same time, the situation that the first suction cup and the second suction cup are damaged can also be reduced.

[0009] Preferably, in the processing step of material taking, the four first suction cups in the first suction cup assembly respectively suck the two corners at one end of the centering support piece. At the same time, the four second suction cups in the second suction cup assembly respectively suck the two corners at the other end of the centering support piece, so that the centering support piece is in a flat state.

[0010] By adopting the above technical solution, the four second suction cups in the second suction cup assembly respectively suck the two corners at the other end of the centering support piece, so that the centering support piece is sucked more stably, reducing the situation of the centering support piece falling. And it can make the centering support piece in a flat state, which is convenient for subsequently feeding the centering support piece flat into the lower die for hole punching.

[0011] Preferably, in the step of material separation, after the first suction cup assembly and the second suction cup assembly suck the top centering support piece, the first suction cup assembly and the second suction cup assembly drive the sucked centering support piece to "point" twice on the top surface of the centering support piece stack, and then drive the sucked centering support piece to move upward to separate the sucked centering support piece from the bottom centering support piece stack.

[0012] By adopting the above technical solution, the stacked centering support pieces generate static friction due to surface contact, making it difficult to separate the top sheet alone. When the first suction cup and the second suction cup smoothly suck the top centering support piece, it is easier to cause the subsequent centering support pieces to be moved along. In this application, during the material separation step, when separating the top centering support piece from the stack of bottom centering support pieces, the top centering support piece is "tapped" twice on the top surface of the stack of bottom centering support pieces. When the situation occurs that the bottom centering support pieces are taken away simultaneously, the taken-away centering support pieces can be sent back to the top surface of the stack of bottom centering support pieces. At this time, the static friction generated between the sucked centering support piece and the taken-away centering support piece has been destroyed. Therefore, after the sucked centering support piece is "tapped" twice, when the sucked centering support piece moves away from the stack of bottom centering support pieces again, the situation of the bottom centering support pieces being taken away simultaneously can be reduced.

[0013] Preferably, in the punching step, after punching one end of the centering support piece, start the conveying drive assembly to drive the conveying assembly to drive the telescopic drive assembly to move towards the punching machine end. Then, drive the first moving suction cup to move downward through the telescopic drive assembly. After the first moving suction cup sucks one end of the centering support piece, the telescopic drive assembly drives the first moving suction cup to move upward, and the conveying drive assembly drives the telescopic drive assembly to move away from the lower die end to complete the movement of the centering support piece.

[0014] By adopting the above technical solution, the punching of the entire centering support piece is completed in several parts. When one part of the centering support piece is punched, the centering support piece is moved through the conveying drive assembly and the telescopic drive assembly for the next part of punching. Completing the punching in multiple parts can improve the punching accuracy.

[0015] Preferably, there are four first moving suction cups. Two first moving suction cups suck one end of the centering support piece, and the other two first moving suction cups suck along the other end of the wide side of the centering support piece.

[0016] By adopting the above technical solution, two first moving suction cups suck one end of the centering support piece, and the other two first moving suction cups suck along the other end of the wide side of the centering support piece, thereby making the movement of the centering support piece more stable, reducing the situation of the centering support piece shaking and being unstable during the movement, and further affecting the punching position.

[0017] Preferably, after moving the centering support piece, make the next part of the centering support piece to be punched correspond to the through hole, and then press the part of the centering support piece to be punched against the top surface of the lower die through the first moving suction cup.

[0018] By adopting the above technical solution, the four first moving suction cups press against the part of the centering support piece that needs to be punched and fit with the top surface of the lower die, reducing the situation where the part of the centering support piece that needs to be punched does not fit with the lower die, and further reducing the situation where the non-fitting between the centering support piece and the lower die affects the punching quality.

[0019] Preferably, in the blanking step, after the centering support piece 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 piece, and the first moving suction cup and the second moving suction cup suck the centering support piece flat.

[0020] By adopting the above technical solution, 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 piece, making the suction of the centering support piece more stable. Moreover, the first moving suction cup and the second moving suction cup suck the centering support piece flat, facilitating subsequent blanking, and the centering support pieces can be stacked flat after blanking.

[0021] Preferably, in the blanking step, after the first moving suction cup and the second moving suction cup suck the centering support piece, the conveying drive assembly drives the telescopic drive assembly to move away from the punching machine until the centering support piece is transferred to the top of the blanking frame, and the centering support piece is placed in the blanking frame.

[0022] By adopting the above technical solution, after the first moving suction cup and the second moving suction cup suck the centering support piece, the centering support piece is moved to the top of the blanking frame, and then the centering support piece is placed in the blanking frame, and the blanking frame stores the centering support piece.

[0023] Preferably, in the blanking step, after the centering support piece is transferred to the top of the blanking frame, the telescopic drive assembly is started again. The telescopic drive assembly drives the first moving suction cup and the second moving suction cup to move downward. After the centering support piece is sent into the blanking frame, the centering support piece is blanked.

[0024] By adopting the above technical solution, during the blanking process of the centering support piece, the centering support piece is sent into the blanking frame and then blanked, thereby reducing the influence on the stacking neatness of multiple centering support pieces when the centering support piece falls into the blanking frame from a relatively high position, and also reducing the situation where the centering support piece is damaged during the blanking process.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. In this application, the first suction cup assembly and the second suction cup assembly are used to sequentially suck multiple centering support pieces stacked on the top surface of the lifting frame. Then, the sucked centering support pieces are moved to the top surface of the lower mold. Through the pressing of the upper mold and the lower mold, holes are punched in the centering support pieces. Then, the material transfer mechanism discharges the centering support pieces that have completed hole punching. Compared with the prior art where laser cutting is used for hole punching, carbonization and blackening will occur around the holes punched in the centering support pieces. This application can reduce the carbonization and blackening of the centering support pieces after hole punching, thereby reducing the impact on the subsequent assembly and performance of the centering support pieces.

[0026] 2. Due to the static friction generated by the surface contact of the stacked multiple centering support pieces, it is difficult to separately separate the top sheet material. When the first suction cup and the second suction cup suck the topmost centering support piece flatly, it is easier to move the subsequent centering support pieces together. In this application, through the material separation step, when separating the top centering support piece from the bottom centering support piece stack, the top centering support piece is "tapped" twice on the top surface of the bottom centering support piece stack. When the bottom centering support pieces are taken away simultaneously, the taken-away centering support pieces can be sent back to the top surface of the bottom centering support piece stack. At this time, the static friction generated between the sucked centering support piece and the taken-away centering support piece has been destroyed. Therefore, after the sucked centering support piece is "tapped" twice and then moves away from the bottom centering support piece stack again, the situation of the bottom centering support pieces being taken away simultaneously can be reduced.

[0031] The following Figures 1-3 further elaborates on this application in conjunction with the attached

[0032] The embodiment of the present application discloses a stamping production process for a high-density arranged speaker centering support piece.

[0033] Refer to Figure 1 , a stamping production process for a high-density arranged speaker centering support piece, comprising the following steps: feeding, picking, material separation, feeding, punching and blanking.

[0034] Refer to Figure 1 and Figure 2 , feeding: Vertically stack a plurality of centering support pieces 6 on the top surface of the lifting frame 1.

[0035] Specifically, first stack a plurality of centering support pieces 6 neatly in the vertical direction. After the stacking of the plurality of centering support pieces 6 is completed, the long sides of the plurality of centering support pieces 6 are in the same vertical plane, and correspondingly, the wide sides of the plurality of centering support pieces 6 are in the same vertical plane. Then, place the stacked plurality of centering support pieces 6 on the top surface of the lifting frame 1. Moreover, the wide side of the centering support piece 6 is parallel to the wide side of the lifting frame 1, the long side of the centering support piece 6 is parallel to the long side of the lifting frame 1, and the centering support piece 6 is located at the bottom of the output end of the picking mechanism 2, thereby completing the feeding of the plurality of centering support pieces 6.

[0036] , picking: Start the picking mechanism 2, and the lifting drive assembly 21 drives the first suction cup assembly 23 and the second suction cup assembly 24 to move downward until the first suction cup assembly 23 and the second suction cup assembly 24 respectively suck the two ends of the topmost centering support piece 6, completing the picking of the centering support piece 6.

[0037] Specifically, start the picking mechanism 2, and the lifting drive assembly 21 drives the mounting seat 22 to move downward, thereby driving the first suction cup assembly 23 and the second suction cup assembly 24 located at the bottom of the mounting seat 22 to move downward until the first suction cup assembly 23 and the second suction cup assembly 24 are in contact with the top surface of the centering support piece 6. When the first suction cup assembly 23 and the second suction cup assembly 24 are in contact with the top surface of the topmost centering support piece 6, during the continuous downward pressing process of the first suction cup assembly 23 and the second suction cup assembly 24, the lifting frame 1 moves downward synchronously, so as to extend the acting time of the first suction cup assembly 23 and the second suction cup assembly 24 on the centering support piece 6, thereby reducing the impact force of the first suction cup assembly 23 and the second suction cup assembly 24 on the centering support piece 6, and further reducing the situation that the centering support piece 6 is damaged by a large impact force. At the same time, it can also reduce the situation that the first suction cup and the second suction cup are damaged.

[0038] Refer to Figure 1 and Figure 2, after the first suction cup assembly 23 and the second suction cup assembly 24 move downward by a corresponding distance synchronously with the lifting frame 1, the first suction cup assembly 23, the second suction cup assembly 24 and the lifting frame 1 stop moving. After that, the four first suction cups in the first suction cup assembly 23 respectively suck the two corners at one end of the centering support piece 6, and at the same time, the four second suction cups in the second suction cup assembly 24 respectively suck the two corners at the other end of the centering support piece 6, so that the four corners on the top surface of the top centering support piece 6 are adsorbed, making the centering support piece 6 in a flat state, and completing the material taking of the top centering support piece 6.

[0039] Material separation: After the first suction cup and the second suction cup suck the top centering support piece 6, the sucked centering support piece 6 is separated from the remaining stack of centering support pieces 6.

[0040] Specifically, after the first suction cup and the second suction cup suck the top centering support piece 6, the lifting drive assembly 21 drives the first suction cup and the second suction cup to move upward, so that the centering support piece 6 sucked flat by the first suction cup and the second suction cup leaves the stack of centering support pieces 6 at the bottom. At this time, the distance that the first suction cup and the second suction cup move upward is short. After that, the lifting drive assembly 21 drives the first suction cup and the second suction cup to move downward again, and the first suction cup and the second suction cup drive the sucked centering support piece 6 to move downward, so that the sucked centering support piece 6 abuts against the stack of centering support pieces 6 at the bottom.

[0041] Refer to Figure 1 and Figure 2 , after that, repeat the above up and down movement actions. The number of repetitions depends on the specific situation. In the embodiment of the present application, the first suction cup and the second suction cup drive the centering support piece 6 to reciprocate up and down twice. When the second downward movement is completed, the lifting drive 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 support piece 6 to move upward until the sucked centering support piece 6 is higher than the horizontal plane of the operation platform.

[0042] That is, after the first suction cup and the second suction cup drive the sucked centering support piece 6 to "point" twice on the top surface of the stack of centering support pieces 6, they drive the sucked centering support piece 6 to move upward to separate the sucked centering support piece 6 from the stack of centering support pieces 6 at the bottom.

[0043] Multiple stacked centering support pieces 6 generate static friction due to surface contact, making it difficult to separate the top sheet alone. When the first suction cup and the second suction cup smoothly suck the top centering support piece 6, it is easier to drive the subsequent centering support pieces 6 away together. Through the material separation step of this application, when separating the top centering support piece 6 from the stack of bottom centering support pieces 6, the top centering support piece 6 is "tapped" twice on the top surface of the stack of bottom centering support pieces 6. When the situation where the bottom centering support pieces 6 are taken away simultaneously occurs, the taken-away centering support pieces 6 can be sent back to the top surface of the stack of bottom centering support pieces 6. At this time, the static friction generated between the sucked centering support piece 6 and the taken-away centering support pieces 6 has been destroyed. Therefore, after the sucked centering support piece 6 is "tapped" twice and then moves away from the stack of bottom centering support pieces 6 again, the situation where the bottom centering support pieces 6 are taken away simultaneously can be reduced.

[0044] Feeding: Move one end of the centering support piece 6 to the top surface of the lower die 32.

[0045] Specifically, after the first suction cup and the second suction cup drive the centering support piece 6 to one 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 further drives the first suction cup and the second suction cup that suck the centering support piece 6 to move horizontally until the centering support piece 6 is moved to the top surface of the operation platform. When one end of the centering support piece 6 is located at the top of the lower die 32, the moving drive assembly 25 pauses moving, the first suction cup and the second suction cup release the suction on the centering support piece 6, and place the centering support piece 6 on the top surface of the workbench. And one end of the centering support piece 6 is located on the top surface of the lower die 32. After that, the moving drive assembly 25 is started again, and the moving drive assembly 25 drives the lifting drive assembly 21 to return to its original position, completing the feeding of the centering support piece 6.

[0046] Refer to Figure 1 and Figure 3 , Punching: After the centering support piece 6 is placed on the top surface of the lower die 32, the upper die 31 moves downward. After the upper die 31 abuts against the lower die 32, the centering support piece 6 is punched, and the centering support piece 6 is moved by the material transfer mechanism 4 to punch the other parts of the centering support piece 6 in sequence.

[0047] Specifically, after one end of the centering support piece 6 is placed on the top surface of the lower die 32, at this time, the part of one end of the centering support piece 6 that needs to be punched corresponds to the through hole of the lower die 32. Start the punching machine 3, the upper die 31 moves downward, after the cutting column of the upper die 31 cuts the centering support piece 6, the cutting column passes through the centering support piece 6 and enters the through hole, completing the punching of one end of the centering support piece 6. Then, the upper die 31 moves upward, and then start the conveying drive assembly 41. The conveying drive assembly 41 drives the telescopic drive assembly 42 to move towards one end of the punching machine 3 until the first moving suction cup assembly 43 is located at the top of one end of the centering support piece 6. Then start the telescopic drive assembly 42, and the telescopic drive assembly 42 drives the first moving suction cup assembly 43 to move downward. After that, the four first moving suction cups suck the top surface of one end of the centering support piece 6. Then start the telescopic drive assembly 42, and the telescopic drive assembly 42 drives the first moving suction cup to move upward. The first moving suction cup lifts the sucked one end of the centering support piece 6. Then start the conveying drive assembly 41, and the conveying drive assembly 41 drives the telescopic drive assembly 42 to move away from one end of the punching machine 3, thereby driving the first moving suction cup that sucks one end of the centering support piece 6 to move. After that, the first moving suction cup releases the suction on the centering support piece 6, completing the movement of the centering support piece 6.

[0048] After moving the centering support piece 6, make the next part of the centering support piece 6 that needs to be punched correspond to the through hole. Then start the conveying drive assembly 41, and the conveying drive assembly 41 drives the telescopic drive assembly 42 to move towards one end of the punching machine 3 again until the four first moving suction cups are located at the top of the next part of the centering support piece 6 that needs to be punched. After that, start the telescopic drive assembly 42, and the telescopic drive assembly 42 drives the first moving suction cup to move downward. The four first moving suction cups are in contact with the top surface of the centering support piece 6, and the four first moving suction cups press the part of the centering support piece 6 that needs to be punched against the top surface of the lower die 32 to fit, reducing the non-fitting situation between the part of the centering support piece 6 that needs to be punched and the lower die 32, and further reducing the situation that the non-fitting between the centering support piece 6 and the lower die 32 affects the punching quality.

[0049] Refer to Figure 1 and Figure 3 After the first moving suction cup presses the centering support piece 6 of the part that needs to complete punching, the telescopic drive assembly 42 drives the first moving suction cup to move upward. Then start the conveying drive assembly 41, and the conveying drive assembly 41 drives the telescopic drive assembly 42 to move away from one end of the punching machine 3 until the first moving suction cup is far away from the punching machine 3. After that, repeat the above punching steps until all the places on the whole centering support piece 6 that need to be punched are completed.

[0050] Material discharging: Transfer the centering support piece 6 that has completed punching to the discharging frame 5 for material discharging.

[0051] Specifically, after the centering support piece 6 is completely punched, start the conveying drive assembly 41. The conveying drive assembly 41 drives the telescopic drive assembly 42 to move towards one end close to the punching machine 3 until the first moving suction cup is located at the top of one end of the centering support piece 6 and the second moving suction cup is located at the top of the other end of the centering support piece 6. Then start the telescopic drive assembly 42. The telescopic drive assembly 42 drives the first moving suction cup and the second moving suction cup to move downward until the first moving suction cup and the second moving suction cup respectively suck the two ends of the long side of the centering support piece 6. After that, start the telescopic drive assembly 42. The telescopic drive assembly 42 drives the first moving suction cup and the second moving suction cup to move upward. The first moving suction cup and the second moving suction cup suck the centering support piece 6 flatly. Then start the conveying drive assembly 41. The conveying drive assembly 41 drives the telescopic drive assembly 42 to move away from one end of the punching machine 3 until the centering support piece 6 is transferred to the top of the blanking frame 5. Then start the telescopic drive assembly 42. The telescopic drive assembly 42 drives the first moving suction cup and the second moving suction cup to move downward. After that, the first moving suction cup and the second moving suction cup release the suction on the centering support piece 6 and place the centering support piece 6 in the blanking frame 5.

[0052] The above are all the preferred embodiments of the present application. This embodiment is only an explanation of the present application and does not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
