Description

Technical Field

[0001] This utility model relates to the field of voice coil motor technology, and more specifically, to a voice coil motor base. Background Technology

[0002] In the manufacturing process of voice coil motors, the base, as the core supporting structure, is typically made of insulating material and contains internal metal circuitry for electrical connections. The coil, as the critical driving component, must be installed on the inner side of the insulating base, while the leads of the metal circuitry are located on the outer surface. This traditional design leads to significant defects in the assembly process: the insulating base must be bent and shaped before the coil can be installed, and the coil leads must be wound from the inside of the insulating base around the edge to the outside to achieve soldering connections with the metal circuitry leads. This winding operation inevitably results in excessive lead length, which easily leads to stress concentration in the bending transition area, causing lead breakage or short circuit risks. Simultaneously, operators must repeatedly manually adjust the direction and position of the leads to ensure soldering reliability. This not only significantly extends the assembly time of a single product but also significantly increases the frequency of manual intervention, leading to a continuous decrease in overall production efficiency and making it difficult to meet the demands of large-scale manufacturing. Utility Model Content

[0003] The problem this invention aims to solve is: how to improve the structure of the voice coil motor base to increase its production efficiency.

[0004] This utility model provides a voice coil motor base, comprising: an insulating base and a metal circuit disposed within the insulating base. The insulating base includes a first injection molding structure and a second injection molding structure, wherein the second injection molding structure is horizontally arranged, and the first injection molding structure includes a first plastic part, a second plastic part, and a third plastic part. The first plastic part, the second plastic part, and the third plastic part are respectively vertically disposed on the outer periphery of the second injection molding structure, and the second plastic part and the third plastic part are disposed opposite to each other. The first plastic part, the second plastic part, and the third plastic part are respectively provided with receiving grooves for mounting coils near the inner sidewall of the second injection molding structure. The receiving grooves include interconnected coil grooves and lead grooves. The coil groove is configured to mount the coil, and the pins of the metal circuit are configured to be exposed on the bottom wall of the lead groove. The lead wires of the coil are used to extend from the coil groove to the lead groove and are soldered to the pins.

[0005] Optionally, the metal circuit includes a first circuit, a portion of which is disposed within the first plastic part and another portion of which is disposed within the second injection molding structure.

[0006] Optionally, the receiving groove includes a first receiving groove formed on the inner sidewall of the first plastic part near the second injection molding structure, and the pins of the first circuit are exposed on the bottom wall of the first receiving groove.

[0007] Optionally, the first receiving slot is provided with multiple slots on the first plastic part, and the multiple pins corresponding to the first circuit are respectively exposed on the bottom wall of the corresponding first receiving slot.

[0008] Optionally, the metal circuit includes a second circuit, a portion of which is disposed within the second plastic part and another portion within the second injection molding structure.

[0009] Optionally, the receiving groove includes a second receiving groove formed in the inner sidewall of the second plastic part facing the third plastic part, and the pins of the second circuit are exposed on the bottom wall of the second receiving groove.

[0010] Optionally, the metal circuit includes a third circuit, a portion of which is disposed within the third plastic part and another portion within the second injection molding structure.

[0011] Optionally, the receiving groove includes a third receiving groove formed on the inner sidewall of the third plastic part facing the second plastic part, and the pins of the third circuit are exposed on the bottom wall of the third receiving groove.

[0012] Optionally, the voice coil motor base further includes a first support element and a second support element, wherein the first support element is disposed within the first injection molding structure; and the second support element is disposed within the second injection molding structure.

[0013] Optionally, a positioning block is provided in the coil slot, and the coil is positioned and installed in the coil slot by the positioning block.

[0014] The voice coil motor base provided by this utility model has, but is not limited to, the following beneficial effects compared with related technologies:

[0015] The voice coil motor base described in this utility model has a second injection-molded structure, which is a horizontally arranged structure formed during the second injection molding process. This structure can be implemented using a flat plate design, for example, serving as a bottom support platform for the base, primarily to provide a stable horizontal foundation. The first injection-molded structure is the structure formed in the first injection molding process, arranged perpendicularly to the outer periphery of the second injection-molded structure, for example, forming a continuous vertical wall around the outer periphery of the second injection-molded structure, primarily to constitute a surrounding mounting area. The first, second, and third plastic parts are three independent plastic part units constituting the first injection-molded structure, designed to provide independent mounting space for the coil. The second and third plastic parts can be understood as symmetrically arranged plastic parts, distributed symmetrically around the outer periphery of the second injection-molded structure, for example, using a 180-degree symmetrical layout. The space enclosed by the first, second, third, and second injection-molded structures is used to mount the voice coil motor body. The first, second, and third plastic parts each have receiving grooves on their inner walls near the second injection molding structure for mounting coils. Each receiving groove is a recessed structure on the inner wall, including a coil groove for mounting the coil and a lead groove for the coil's leads to extend into. The leads of the metal circuit are exposed on the bottom wall of the lead groove. Lead exposure means that during injection molding, the mold controls the lead portion to prevent it from being covered by insulating material. This can be achieved by reserving a recessed area or partially interrupting the injection molding process. For example, a groove matching the lead shape can be provided on the bottom wall of the groove to ensure the lead end face is exposed. This is mainly to enable direct soldering connection of the coil's leads. Therefore, this invention directly exposes the metal circuit leads on the bottom wall of the lead groove, avoiding the step of the lead wire needing to wrap around from the inside to the outside of the insulating base, thus solving the problems of excessively long and easily bent leads.

[0027] In the traditional manufacturing process of voice coil motor bases, the coil leads must be wound from the inside of the insulating base to the outside and soldered to the metal circuit pins, resulting in redundant lead paths and increased exposed length. This problem stems from the spatial isolation between the coil mounting position and the pin position after the insulating base is integrally injection molded. The leads generate an extra extension when winding around the sidewall structure, making them prone to bending and deformation under mechanical vibration or assembly stress. This bending not only causes poor solder joint contact but also forces operators to frequently interrupt the production process for manual adjustments, negatively impacting the production continuity and assembly stability of the base.

[0028] In this regard, such as Figures 1 to 3 As shown in the figure, a voice coil motor base according to an embodiment of the present invention includes: an insulating base and a metal circuit disposed within the insulating base. The insulating base includes a first injection molding structure and a second injection molding structure 1, wherein the second injection molding structure 1 is horizontally arranged, and the first injection molding structure includes a first plastic part 2, a second plastic part 3, and a third plastic part 4. The first plastic part 2, the second plastic part 3, and the third plastic part 4 are respectively vertically disposed on the outer periphery of the second injection molding structure 1, and the second plastic part 3 and the third plastic part 4 are disposed opposite to each other. The first plastic part 2, the second plastic part 3, and the third plastic part 4 are respectively provided with receiving grooves for mounting a coil 100 near the inner sidewall of the second injection molding structure 1. The receiving groove includes a coil groove and a lead groove that are interconnected. The coil groove is configured to mount the coil 100, and the pins of the metal circuit are configured to be exposed on the bottom wall of the lead groove. The lead wire 1001 of the coil 100 is used to extend from the coil groove to the lead groove and be soldered to the pin.

[0029] In this embodiment, the second injection molding structure 1 refers to the horizontally arranged structure formed during the second injection molding process. It can be implemented using a flat plate design, such as serving as a bottom support platform for the base, primarily to provide a stable horizontal foundation. The first injection molding structure refers to the structure formed in the first injection molding, which is arranged perpendicularly to the outer periphery of the second injection molding structure 1, for example, forming a continuous vertical wall around the outer periphery of the second injection molding structure 1, primarily to constitute a surrounding installation area. The first plastic part 2, the second plastic part 3, and the third plastic part 4 refer to three independent plastic part units constituting the first injection molding structure, intended to provide independent installation space for the coil 100. The second plastic part 3 and the third plastic part 4 can be understood as symmetrically arranged plastic parts, symmetrically distributed around the outer periphery of the second injection molding structure 1, for example, using a 180-degree symmetrical layout. The space enclosed by the first plastic part 2, the second plastic part 3, the third plastic part 4, and the second injection molding structure 1 is used to install the voice coil motor body. The first plastic part 2, the second plastic part 3, and the third plastic part 4 each have receiving grooves on their inner sidewalls near the second injection molding structure 1 for mounting the coil 100. Each receiving groove is a recessed structure on the inner sidewall, including a coil groove for mounting the coil 100 and a lead groove for the lead wire 1001 of the coil 100 to extend into. The pins of the metal circuit are exposed on the bottom wall of the lead groove. Pin exposure means that during the injection molding process, the mold controls the pin portion to prevent it from being covered by insulating material. This can be achieved by reserving a recessed area or by partially interrupting the injection molding process. For example, a groove matching the shape of the pin can be provided on the bottom wall of the groove to ensure that the pin end face is exposed. This is mainly to enable direct soldering connection of the lead wire 1001 of the coil 100. Therefore, this invention, by directly exposing the pins of the metal circuit on the bottom wall of the lead groove, avoids the step of the lead wire 1001 needing to wrap around from the inside to the outside of the insulating base, thus solving the problem of excessively long and easily bent lead wires.

[0030] Optionally, the metal circuit includes a first circuit 5, a portion of which is disposed within the first plastic part 2, and another portion of which is disposed within the second injection molding structure 1.

Figure 1 The base portion (in the plane where the XY axis is located) is intended to be combined with the first plastic part 2 to form a complete insulating base, while also accommodating the extension portion of the first circuit 5.

[0032] Specifically, this solution involves segmenting the first circuit 5 into the first plastic part 2 and the second injection molding structure 1. During the first injection molding process, a portion of the first circuit 5 is fixed within the first plastic part 2, thereby stabilizing the circuit position in the vertical direction. During the second injection molding process, the remaining portion of the first circuit 5 is integrated into the second injection molding structure 1, forming a continuous connection in the horizontal direction.

It can be implemented by different cross-sectional shapes such as rectangular groove, U-shaped groove or trapezoidal groove. Its purpose is to provide a precise installation and positioning area for the coil 100 and avoid the lead wire 1001 from going around. The pin of the first circuit 5 is exposed to the bottom wall of the first receiving groove, which means that the pin end is directly exposed on the bottom surface of the groove. It can be implemented by pre-reserving holes or partially embedding during the injection molding process. Its purpose is to enable the lead wire 1001 of the coil 100 to be directly soldered to the pin in the groove and eliminate the extra path.

[0040] Specifically, this solution involves segmenting the second circuit 6 into the second plastic part 3 and the second injection molding structure 1.
