Description

Technical Field

[0001] This utility model belongs to the field of microphone manufacturing technology, specifically relating to a microphone cable bonding fixture. Background Technology

[0002] A microphone is an energy conversion device that converts sound signals into electrical signals. The ribbon cable, or FPC cable, is used internally by the microphone due to its high flexibility and stable signal transmission characteristics. It is responsible for transmitting the electrical signals converted from sound signals from the microphone's pickup section to the amplifier circuit or audio processing equipment. During microphone assembly, to prevent the ribbon cable from shifting or vibrating during use, which could lead to unstable signal transmission or damage, the ribbon cable is usually fixed inside the microphone.

[0003] In related technologies, the microphone includes a housing, and the inner wall of the housing is provided with a mounting position for fixing the ribbon cable. When attaching the microphone to the ribbon cable, glue is applied to the surface of the ribbon cable manually, and then the ribbon cable is inserted into the housing. The ribbon cable is bonded to the inner wall of the housing at the mounting position.

[0004] However, since the housing is usually cylindrical, it is difficult to ensure that the ribbon cable is pasted in a specific mounting position when manually inserting it, which affects the efficiency and accuracy of the microphone cable pasting operation. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a microphone cable attaching fixture, which is easy to operate and ensures that the ribbon cable is attached to the mounting position, thereby improving the efficiency and accuracy of microphone cable attaching operations.

[0006] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0007] This utility model provides a microphone cable mounting fixture, including an adsorption element for adsorbing ribbon cables; and a positioning mold with a cable passage, wherein one end of the ribbon cable is adsorbed and positioned by the adsorption element, and the other end passes through the cable passage; the positioning mold is driven by a driving element, which drives the positioning mold to move closer to or away from the adsorption element; a housing is sleeved on the outside of the positioning mold and the adsorption element, the driving element drives the positioning mold away from the adsorption element, and the positioning mold presses the housing to bring the mounting position closer to the adsorption element.

[0008] In some implementations, the positioning mold has an adsorption groove, and the adsorption element enters or leaves the adsorption groove.

[0009] In some implementations, when the adsorption element is inserted into the adsorption tank, the cable is adsorbed and positioned in the adsorption tank by the adsorption element, and the adsorption tank is adapted to the cable.

[0010] In some implementations, the adsorption element has a vacuum hole, and the adsorption element vacuum adsorbs the cable at the vacuum hole.

[0011] In some implementations, the wire-passing channel includes an open section and a narrow section, and the cable passes through the open section into the narrow section.

[0012] In some implementations, a base is provided on one side of the adsorption element, the adsorption element is detachably connected to the base, and the positioning mold is slidably disposed on the base.

[0013] In some implementations, a guide component is provided between the positioning module and the base to guide the positioning module to slide.

[0014] In some implementations, an adjustment component is provided between the positioning module and the base to limit and adjust the movement distance of the positioning module.

[0015] In some implementations, the adjusting component includes an adjusting rod connected to the positioning mold. The adjusting rod includes an adjusting section that passes through the base and is slidably connected to the base. A first limiting member is provided at the beginning of the adjusting section in the sliding direction, and a second limiting member is provided at the end. The first limiting member and the second limiting member are respectively provided on both sides of the base, and the first limiting member and the second limiting member adjust the length of the adjusting section.

[0016] In some implementations, elastic pads are provided on the side of the first limiting member near the base and the side of the second limiting member near the base.

[0017] In summary, this utility model has at least the following advantages:

[0018] The microphone cable attaching fixture provided by this utility model allows for the placement of the microphone cable. One end of the cable is attracted by an adsorption element, and the other end is then inserted into a cable passage, thus positioning the cable. A housing is fitted over the adsorption element and positioning mold. When the driving element moves the positioning mold away from the adsorption element, the positioning mold presses against the housing, causing it to move relative to the adsorption element. This movement brings the mounting position closer to the adsorption element. Once the cable is attached to the mounting position, the housing is pulled out from the positioning mold and adsorption element. Because the end of the cable attached to the mounting position is fixed, the end of the cable inserted into the cable passage can be pulled out of the passage and inserted into the housing as the positioning mold is removed, completing the cable attaching operation.

[0019] Compared to traditional manual wire bonding, the suction device can position the wires during the bonding process. At the same time, the positioning mold and the suction device work together to perform automatic wire bonding, which helps to ensure the accuracy of wire bonding and improve the efficiency of microphone wire bonding.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this utility model, not all embodiments.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] Example 1:

[0040] Please see the appendix Figure 1 and Figure 2 The microphone cable attaching fixture of this utility model can be used in microphone assembly equipment to automatically insert and attach the ribbon cable 7, which helps to improve the efficiency and accuracy of assembling the ribbon cable 7 and the housing 6.

[0041] This utility model discloses a microphone cable mounting fixture, including an adsorption component 1. The adsorption component 1 adsorbs and positions the ribbon cable 7. Specifically, the adsorption component 1 can be a horizontally positioned long rod, which facilitates the placement of the flat ribbon cable 7 on its surface. The ribbon cable 7 includes an adhesive end 71 and a free end 72. The adhesive end 71 is coated with adhesive and can be adhered to the mounting position 61 inside the housing 6. When the ribbon cable 7 is inserted into the housing 6, the free end 72 extends out of the housing 6 to connect to the plug. The ribbon cable 7 can be electrically connected to the PCBA through the plug. When the adsorption component 1 adsorbs the ribbon cable 7, it adsorbs the side of the adhesive end 71 that is not coated with adhesive.

[0042] A positioning mold 2 is provided on one side of the adsorption component 1. Specifically, the positioning mold 2 includes a mold body 24 and a seat body 25. The shape of the mold body 24 is adapted to the shape of the shell 6. When the mold body 24 is inserted into the shell 6, there is a gap between it and the inner wall of the shell 6.

[0043] The mold body 24 has a threading channel 21. Before the ribbon cable 7 is assembled with the housing 6, the free end 72 of the ribbon cable 7 is inserted into the threading channel 21. In some specific embodiments shown, the threading channel 21 is a square channel arranged parallel to the adsorption member 1, and the free end 72 can smoothly pass into the threading channel 21. When positioning the ribbon cable 7, the adhesive end 71 is adsorbed and fixed by the adsorption member 1, and the free end 72 is wound around to the threading hole and inserted into the threading hole. The adsorption member 1 and the positioning mold 2 fix the ribbon cable 7 during the threading process to improve the problem of the ribbon cable 7 moving randomly and affecting the threading accuracy.

[0044] The positioning mold 2 is connected to a drive component 22. Specifically, the drive component 22 is preferably, but not limited to, a cylinder. The output end of the drive component 22 is connected to the base 25. As shown in some specific embodiments, the drive component 22 can drive the positioning mold 2 to move up and down by changing its stroke, so that the positioning mold 2 is closer to or away from the adsorption component 1.

[0045] Before attaching the microphone cable, apply glue to the adhesive end 71 of the ribbon cable 7. The suction member 1 attaches to the side of the adhesive end 71 that is not coated with glue, and the free end 72 is inserted into the cable passage 21. Then, the housing 6 is placed on the outside of the suction member 1 and the positioning mold 2. The suction member 1 is located inside the housing 6 and is opposite to the mounting position 61, that is, the mounting position 61 and the adhesive side of the adhesive end 71 are in a relative position.

[0046] The driving component 22 drives the positioning mold 2 away from the adsorption component 1. The positioning mold 2 presses the housing 6 to move the housing 6 away from the adsorption component 1. The mounting position 61 inside the housing 6 then approaches the adsorption component 1. When the adsorption component 1 and the inner wall of the housing 6 at the mounting position 61 come into contact, the inner wall of the housing 6 at the mounting position 61 and the adsorption component 1 cooperate to squeeze the adhesive end 71, so that the adhesive end 71 is bonded to the mounting position 61 and the adhesive end 71 is fixed inside the housing 6.

[0047] When the housing 6 is pulled out, it moves away from the suction element 1 and the positioning mold 2. The ribbon cable 7 is pulled out from the wire passage 21 and inserted into the housing 6, completing the wire bonding operation. The free end 72, pulled out from the wire passage 21, extends out of the housing 6 and can be connected to a plug. Compared with the traditional manual wire bonding method, the positioning mold 2 is moved by the driving element 22 to achieve automatic bonding, which helps improve the efficiency of microphone wire bonding. At the same time, the suction element 1 and the positioning mold 2 can work together to fix the ribbon cable 7, ensuring that the ribbon cable 7 is accurately bonded to the mounting position 61, thus guaranteeing the accuracy of the wire bonding operation.

[0048] Example 2:

[0049] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the adsorption element 1 and the positioning mold 2 of this utility model. Please refer to [link / reference]. Figures 2-7 .

[0050] See Figures 2-5 In this embodiment, the adsorption component 1 has a vacuum hole 11, which is specifically an L-shaped hole. The adsorption component 1 uses the vacuum hole 11 to vacuum-adsorb the adhesive end 71. Specifically, the adsorption component 1 is connected to the vacuum hole 11 via a vacuum pipe 12, which is connected to a vacuum generator 13. The vacuum generator 13 uses the vacuum pipe 12 to evacuate the vacuum hole 11.

[0051] See Figure 6 In a preferred embodiment, the positioning mold 2 has an adsorption groove 23. The adsorption component 1 enters or leaves the adsorption groove 23. Before the microphone cable is attached, the adsorption component 1 is located in the adsorption groove 23, which facilitates the simultaneous insertion of the adsorption component 1 and the positioning mold 2 into the housing 6 for microphone cable attachment. Specifically, the adsorption component 1 is adapted to the adsorption groove 23. When the adsorption component 1 is inserted into the adsorption groove 23, the ribbon cable 7 is adsorbed and positioned in the adsorption groove 23 by the adsorption component 1. The adsorption groove 23 is adapted to the ribbon cable 7 and can limit the ribbon cable 7, so that the ribbon cable 7 maintains the correct pasting position when it is adsorbed and positioned, that is, the ribbon cable 7 can be accurately pasted to the installation position 61 when it is attached, making the operation convenient.

[0052] As shown in some specific embodiments, the positioning mold 2 has a wire placement port 231 at the opening of the adsorption groove 23. The wire placement port 231 is a notch opened on the surface of the positioning mold 2. The setting of the wire placement port 231 is conducive to improving the convenience of operation, making it easier for the operator to put the cable 7 into the adsorption groove 23 so that the adsorption component 1 adsorbs the cable 7.

[0053] See Figure 7 In a preferred embodiment, the wire passage 21 includes an open section 211 and a narrow section 212. When positioning the wire 7, the free end 72 passes through the open section 211 into the narrow section 212, which facilitates the wire 7 to pass smoothly into the wire passage 21 and improves the convenience of operation.

[0054] See Figure 2 , Figure 6 and Figure 7 Before attaching the microphone cable, the adsorption component 1 is located in the adsorption groove 23. The adhesive end 71 is placed into the adsorption groove 23, with the adhesive end 71 on the surface of the adsorption component 1. The adsorption component 1 uses vacuum holes 11 to vacuum-adsorb the adhesive end 71. The housing 6 is fitted over the outside of the adsorption component 1 and the positioning mold 2. The driving component 22 drives the positioning mold 2 to descend relative to the adsorption component 1. The adsorption component 1 is exposed and gradually detaches from the adsorption groove 23. The positioning mold 2 presses down on the housing 6 to bring the mounting position 61 closer to the adsorption component 1. The adsorption component 1 and the inner wall of the housing 6 at the mounting position 61 abut against each other. The adhesive end 71 is attached to the mounting position 61. The positioning mold 2 continues to descend and drives the housing 6 to press down on the adsorption component 1. There is further pressing pressure between the housing 6 at the mounting position 61 and the adsorption component 1, which helps to improve the stability of the adhesive end 71.

[0055] Example 3:

[0056] The difference between this embodiment and the above embodiments is that this embodiment further optimizes the structure of the positioning module 2 of this utility model. Please refer to [link / reference]. Figure 8 and Figure 9 .

[0057] See Figure 8 In this embodiment, a base 3 is provided on one side of the adsorption component 1. The adsorption component 1 and the base 3 are detachably connected. Specifically, the adsorption component 1 and the base 3 can be assembled by screws, which is conducive to timely replacement of damaged adsorption components 1.

[0058] The base 25 of the positioning mold 2 is slidably connected to the base 3. In a preferred embodiment, a guide component 31 for guiding the positioning mold 2 to slide is provided between the base 25 and the base 3. Specifically, the guide component 31 may include a guide rail 311, which is disposed on the base 3. A guide block 312 is slidably disposed on the guide rail 311. The guide block 312 is detachably connected to the base 25. When the driving member 22 drives the positioning mold 2 to move up and down, the guide block 312 slides along the guide rail 311 to guide and limit the sliding direction of the positioning mold 2.

[0059] In a preferred embodiment, an adjustment component 4 for limiting and adjusting the movement distance of the positioning mold 2 is provided between the base 25 and the base 3. As shown in some specific embodiments, the adjustment component 4 includes an adjustment rod 41, which is specifically arranged vertically and connected to the base 25. The adjustment rod 41 includes an adjustment section 411, which passes through the base 3 and is slidably connected to the base 3.

[0060] The adjusting section 411 has a first limiting member 42 at the beginning of the sliding direction and a second limiting member 43 at the end. Both the first limiting member 42 and the second limiting member 43 are sleeved on the adjusting rod 41 and are located on opposite sides of the base 3. Specifically, the adjusting rod 41 is a threaded rod, and both the first limiting member 42 and the second limiting member 43 can be double nuts, which helps reduce the possibility of the first limiting member 42 and the second limiting member 43 loosening and falling off.

[0061] Specifically, the first limiting member 42 and the second limiting member 43 are arranged vertically. The length of the adjustable section 411 can be adjusted by the first limiting member 42 to limit the downward distance of the adjusting rod 41, and the second limiting member 43 to limit the upward distance of the adjusting rod 41. At this time, the first limiting member 42 and the second limiting member 43 limit the stroke of the driving member 22 through the adjustable section 411.

[0062] Furthermore, elastic pads 44 are provided on the side of the first limiting member 42 near the base 3 and on the side of the second limiting member 43 near the base 3. Specifically, the elastic pads 44 are preferably, but not limited to, rubber pads, such as polyurethane pads. The provision of elastic pads 44 helps to reduce the wear of the first limiting member 42 and the second limiting member 43, thereby reducing the error in the lifting and positioning of the adjusting section 411.

[0063] The adjustment component 4 can adjust the length of the adjustment section 411 according to the specifications of the housing 6 and the ribbon cable 7, thereby adjusting the stroke of the drive component 22 so that the ribbon cable 7 can be smoothly pasted at the mounting position 61. When the microphone is pasted, the drive component 22 drives the positioning mold 2 to descend, thereby causing the housing 6 to descend. The adjustment section 411 passes through the base 3 and descends relative to the base 3. When the first limiting member 42 descends to abut against the base 3, the drive component 22 stops working. At this time, the adsorption member 1 is in the state of being detached from the adsorption groove 23, while the positioning mold 2 presses down on the housing 6 so that the housing 6 and the adsorption member 1 are pressed against each other at the mounting position 61, and the pasting end 71 is pasted to the mounting position 61. After the wire is attached, the housing 6 is pulled out from the adsorption component 1 and the positioning mold 2. The driving component 22 drives the positioning mold 2 to rise. The adjusting section 411 passes through the base 3 and rises relative to the base 3. When the second limiting component 43 rises to the state of abutting against the base 3, the positioning mold 2 returns to its position. The first limiting component 42 and the second limiting component 43 adjust the length of the adjusting section 411 to achieve the effect of adjusting the stroke of the driving component 22, which is flexible in use.

[0064] See Figure 9 In a preferred embodiment, an operation box 5 is provided on one side of the base 3. The base 3 is disposed on the outer wall of the operation box 5. The drive unit 22 and the vacuum generator 13 are both disposed inside the operation box 5, which serves a protective function. As shown in some specific embodiments, the operation box 5 is provided with a power switch 51 for connecting or disconnecting the power supply, and a start switch 52 for starting and stopping the drive unit 22. The power switch 51 and the start switch 52 are electrically connected to the drive unit 22. The control methods of the power switch and the start switch 52 are known to those skilled in the art and are achievable, and will not be described in detail in this embodiment.

[0065] Specifically, the control box 5 is equipped with a display screen 53, through which the pressure holding time can be set. Similarly, the configuration of the display screen 53 is known to those skilled in the art and is achievable, and will not be described in detail in this embodiment.
