Description

Technical Field

[0001] This utility model relates to VCM driver chip processing equipment, specifically to a VCM driver chip silicone mounting equipment. Background Technology

[0002] VCM driver chip, or voice coil motor in electronics, is a type of motor. Its main principle is to use a permanent magnetic field to control the position of a spring or mover by changing the current in the motor's coil, thereby moving the lens and achieving autofocus. This is illustrated in the high-precision semiconductor base assembly and its manufacturing method disclosed in Chinese invention patent CN115102322A. Figure 2 As shown, commonly used VCM driver chips have a square structure with an inner hole in the middle.

[0003] During the manufacturing process of VCM driver chips, silicone strips need to be attached to their periphery. In existing technologies, this is usually done manually. However, because the VCM driver chip itself is small, manual attachment of silicone strips is difficult and inefficient due to the chip's small size and the need to attach them to multiple sides.

The second moving unit is disposed at the output end of the first moving unit, and the lifting module one is disposed at the output end of the second moving unit. The output end of the lifting module one is connected to the adsorption head one.

[0012] Furthermore, the orientation of the first moving unit and the orientation of the second moving unit intersect each other.

[0013] Furthermore, the VCM driver chip silicone mounting equipment also includes a punching assembly, which includes a lifting frame, a lifting cylinder mounted on the lifting frame, and a cutting frame mounted on the output end of the lifting cylinder.

[0016] The beneficial effects of this invention are as follows: It provides a silicone mounting device for a VCM driver chip, including a pressing component, a holding component, a mounting component, and a drive motor. The pressing component includes a first fixing block and a second fixing block that fit together. This invention axially presses the VCM driver chip by pre-positioning a positioning block on the first fixing block through the inner hole of the VCM driver chip and embedding it into the fixing hole on the second fixing block. This prevents the VCM driver chip from easily shaking when mounting silicone strips on its peripheral sidewalls. Furthermore, the mounting efficiency is improved by simply controlling the rotation of the VCM driver chip via the drive motor. Attached Figure Description

[0029] Specifically, in this embodiment, two clamping pads 222 are provided. The clamping pads 222 are made of silicone material. The VCM driver chip 200 is square. Since the end face of the VCM driver chip 200 has two grooves 201, the clamping pads 222 can be adapted to these two grooves 201, so that the first fixing block 21 and the second fixing block 22 can better clamp the VCM driver chip 200 and improve the clamping effect.

The first abutment block 31 and the second abutment block 32 both abut against the compression assembly 20. One end of the first abutment block 31 away from the compression assembly 20 is rotatably connected to the mounting bracket 33. One end of the compression spring 34 is fixedly connected to the mounting bracket 33, and the other end of the compression spring 34 is connected to the second abutment block 32. Specifically, in this embodiment, the first abutting block 31 is provided with abutting groove 311, the groove wall of the abutting groove 311 abuts against the end of the first fixing block 21 away from the VCM driving chip 200, the end of the first abutting block 31 away from the first fixing block 21 is fixedly connected to the output shaft of the drive motor 50, the end of the second abutting block 32 away from the compression spring 34 is provided with abutting rod 321, the abutting rod 321 and the abutting hole 223 on the second fixing block 22 are engaged, the end of the abutting rod 321 and the abutting hole 223 are conical structures, so that when the second abutting block 32 and the first abutting block 31 cooperate to press the VCM driving chip 200, the first abutting block 31 can drive the pressing assembly 20 and the VCM driving chip 200 to rotate relative to the second abutting block 32.

[0031] The mounting assembly 40 includes a moving unit and an adsorption head 44 disposed at the output end of the moving unit. The adsorption head 44 transfers the silicone strip onto the sidewall of the VCM driver chip 200 via the moving unit for mounting. The moving unit includes a first moving unit 41, a second moving unit 42, and a lifting module 43. The second moving unit 42 is disposed at the output end of the first moving unit 41, and the lifting module 43 is disposed at the output end of the second moving unit 42. The output end of the lifting module 43 is connected to the adsorption head 44. The setting directions of the first moving unit 41 and the second moving unit 42 intersect each other. Specifically, in this embodiment, the first moving unit 41 is disposed along the width direction of the frame 10, the second moving unit 42 is disposed along the length direction of the frame 10, and the lifting module 43 is disposed along the height direction of the frame 10.

[0033] The drive motor 50 is mounted on the frame 10. The output end of the drive motor 50 passes through the mounting bracket 33 and is fixedly connected to the corresponding first support block 31. The drive motor 50 is used to drive the VCM drive chip 200 to rotate so that the side wall of the VCM drive chip 200 that needs to be attached to the silicone strip and the silicone strip adsorbed by the adsorption head 44 are parallel to each other and facing the silicone strip.

[0034] The VCM driver chip silicone mounting equipment 100 also includes a punching assembly 60, which includes a lifting frame 61, a lifting cylinder 62 mounted on the lifting frame 61, and a cutting frame 63 mounted on the output end of the lifting cylinder 62.

Furthermore, the punching assembly 60 also includes mounting protrusions 632 mounted on the cutting frame 63. The mounting protrusions 632 are positioned between two adjacent cutters 631 and correspond to the silicone strip. When the cutters 631 cut the edge of the silicone strip, the mounting protrusions 632 can hold the silicone strip in place, facilitating the cutters 631 to apply force to the edge of the silicone strip and remove waste material, thus improving the cutting efficiency of the cutters 631.

[0035] The VCM driver chip silicone mounting equipment 100 also includes a conveying unit 70, which includes a sliding module 71 and a platform 72 for placing silicone strips. A first moving unit 41 is located above the sliding module 71. The output end of the sliding module 71 is fixedly connected to the platform 72. The sliding module 71 is used to control the platform 72 to move from the punching assembly 60 to the junction of the sliding module 71 and the moving unit.

[0036] The VCM driver chip silicone mounting equipment 100 also includes a feeding unit 80, which includes a second platform 81, a third moving unit 82, and a second lifting module 83 mounted on the frame 10, as well as a plurality of suction heads 84 mounted on the output end of the second lifting module 83. The third moving unit 82 is arranged along the width direction of the frame 10, the second lifting module 83 is arranged along the height direction of the frame 10, the second lifting module 83 is located at the output end of the third moving unit 82, and the suction heads 84 are arranged facing the platform.

[0037] Specifically, in this embodiment, the first moving unit 41, the second moving unit 42, the first lifting module 43, the third moving unit 82, the second lifting module 83, and the sliding module 71 all adopt the lead screw transmission structure in the prior art.

[0038] The VCM driver chip silicone mounting equipment 100 also includes a dispensing machine mounted on the frame 10. The dispensing machine is located on one side of the clamping assembly 20, and the dispensing head of the dispensing machine is positioned towards the side wall of the VCM where the silicone strip needs to be mounted. In this embodiment, the specific structure of the dispensing machine is prior art. Any dispensing machine capable of performing the dispensing function can be used as the dispensing machine in this embodiment of the present invention, and no limitation is imposed in this embodiment.

[0039] The working process of the VCM driver chip silicone mounting device 100 provided in this embodiment is as follows: First, the VCM driver chip 200 is axially pressed in the order of the first fixing block 21, the VCM driver chip 200, and the second fixing block 22, and the pressing pad 222 is pressed on the two corresponding grooves 201 on the VCM driver chip 200. Then, one end of the first fixing block 21 abuts against the abutting groove 311 on the first abutting block 31, and the abutting hole 223 on the second fixing block 22 and the abutting rod 321 on the second abutting block 32 abut against each other. Then, the first abutting block 31 is controlled by the drive motor 50 to drive the side wall of the VCM driver chip 200 that needs to be mounted with silicone strips to rotate from a vertical state to a horizontal state and face upwards. Then, the silicone strip is applied to the side wall of the VCM driver chip 200 that needs to be mounted with silicone strips by the dispensing machine. Next, several uncut silicone strips are placed on the second platform 81. The third moving unit 82 and the second lifting module 83 work together to control the second suction head 84 to transfer the uncut silicone strips to the first platform 72. The sliding module 71 then controls the first platform 72 to move below the cutting frame 63. The lifting cylinder 62 controls the cutting frame 63 to descend until the cutter 631 cuts the edges and waste of each silicone strip. Then, the sliding module 71 controls the first platform 72 to move to the junction with the first moving unit 41. The first moving unit 41, the second moving unit 42, and the lifting module 43 work together to control the adsorption head 44 to adsorb and transfer the silicone strip to the side wall of the VCM driver chip 200 where the silicone strip needs to be attached. The drive motor 50 is started repeatedly to control the first supporting block 31 to rotate the side wall of the VCM driver chip 200 where the silicone strip needs to be attached from a vertical state to a horizontal state, facing upward. After repeating the above steps three times, the silicone strip attachment on the side wall of the VCM driver chip 200 is completed.

[0040] Beneficial effects: This utility model pre-presses the VCM driver chip 200 axially by passing the positioning block 221 on the first fixing block 21 through the inner hole of the VCM driver chip 200 and embedding it into the fixing hole 211 on the second fixing block 22. This makes the VCM driver chip 200 less prone to shaking when attaching silicone strips 300 to the peripheral sidewalls of the VCM driver chip 200. Moreover, the requirement to attach silicone strips 300 to each sidewall of the VCM can be met simply by controlling the rotation of the VCM driver chip 200 through the drive motor 50. Compared with the prior art, the attachment efficiency is improved.
