[0026] This invention is mainly used for the process control of the input voice coil motor of the lens assembly in optical image stabilization module products, as well as the UV adhesive application and curing process after completion.

[0027] This invention includes a turntable 25 with a mounting plate and a material holder 3 on the mounting plate. The material holder 3 shown in the figure has four workstations 4. Each workstation 4 on the turntable 25 has a height adjustment device 26, which rotates together with the turntable. To be precise, the height adjustment device 26 is integrated with the workstation 4.

[0028] Along the rotation direction of the turntable 25, there are a level measuring instrument 27, a UV glue dispensing device 28, a UV curing lamp 29, and a black glue dispensing device 30. The height adjustment device 26 can adjust the height of the material in the workstation. The level measuring instrument 27 is used to detect the levelness and height of the material. The UV glue dispensing device 28 is used to apply UV glue to the material. The UV curing lamp 29 is used for applying UV glue to the material. The black glue dispensing device 30 is used for applying black glue to the material.

[0029] The bottom of the workstation 4 of this invention has a through hole that passes through the material seat 3; a secondary rack 7 is provided on the mounting plate, and the secondary rack 7 corresponds to the workstation 4 of the material seat 3. As shown in the figure, there are four secondary racks 7 arranged in parallel. Multiple upright plates 9 are vertically fixed on the mounting plate, and pressure plates 10 are installed between the upright plates 9. The pressure plates 10 are coaxially equipped with a secondary gear 8, which meshes with the secondary rack 7. The pressure plates 10 are arranged corresponding to the workstation 4. When the secondary rack 7 moves, it drives the secondary gear 8 to rotate, thereby driving the pressure plates 10, which are coaxial with the secondary gear 8, to rotate, so that the pressure plates 10 rotate to cover or open the workstation 4. The shape of the pressure plates 10 is not limited, as long as it can fit the material.

[0030] Each rack 7 can be moved back and forth using a cylinder or other drive mechanism.

[0031] As shown in the figure, in order to make each secondary rack 7 move simultaneously, each secondary rack 7 is connected to a drive rod 6, and the drive rod 6 is perpendicular to the secondary rack 7. The mounting plate has a lower main rack 5, one end of the drive rod 6 is fixedly connected to the lower main rack 5, the upper end of the lower main rack 5 is meshed with the main gear 2, and the upper main rack 1 is meshed above the main gear 2. The upper main rack 1, the lower main rack 5, and the secondary rack 7 are placed in parallel.

[0032] A top-feeding motor 11 is installed below the mounting plate. The top of the top-feeding motor 11 drives a lead screw, and a lead screw nut 18 is fitted on the lead screw. A top column 13 is provided at the upper end of the lead screw. An upper top fixture is installed on the top of the top column 13. The upper top fixture passes through the through hole of the station 4. The station 4 can place materials. If the height of the material is insufficient, the top-feeding motor 11 will work to drive the top column 13 to move upward. The bottom of the material will contact the upper top fixture of the top column 13. The top column 13 will continue to rise to the appropriate position. If the position of the station is too high, the top-feeding motor 11 will drive the top column 13 to move downward to the appropriate position, thereby adjusting the height of the material.

[0033] The top column 13 and the upper fixture both have axial holes and external air pipes. Vacuuming is achieved through the air pipes to adsorb materials.

[0034] The top-feeding motor 11 of the present invention has a mounting base 12 installed on its upper part. A connecting column 16 is vertically mounted on the mounting base 12. The connecting column 16 has a guiding and anti-rotation function and is parallel to the rotating shaft of the top-feeding motor 11. The upper end of the top-feeding motor 11 has a fixing plate 17, which has a connecting hole 19 for the connecting column 16 to pass through. A lead screw nut 18 is installed on the upper end face of the fixing plate 17.

[0035] The lower part of the top column 13 of the present invention is connected to a connecting block 14, and a guide column 15 is installed on the connecting block 14. The guide column 15 passes through the mounting plate and is parallel to the top column 13 to keep the top column 13 moving smoothly. The top column 13 and the guide column 15 are perpendicular to the connecting block 14.

[0036] The present invention is equipped with a material detection sensor 21, which is mounted on a slide plate 20. The slide plate 20 is driven by a slide plate cylinder 22. The slide plate 20 is connected to and fixed to the upper main rack 1 through a push rod 23. The slide plate 20 is also equipped with a measuring head 24 for quantitative movement control of the slide plate 20.

[0037] Before the material loading process, the slide plate 20 moves the material detection sensor 21 forward to the station 4. The push rod 23 pushes the upper main rack 1 forward, the main gear 2 rotates, and drives the lower main rack 5 backward. The drive rod 6 is fixedly connected to the lower main rack 5, so the drive rod 6 moves backward. At the same time, the secondary rack 7 is fixed to the drive rod 6, so the secondary rack 7 moves backward. The secondary gear 8 rotates, the pressure plate 10 opens, and the material is loaded into the station 4. The material detection sensor 21 detects whether the material has been loaded into the designated position.

[0038] After the material is fed in, the slide plate 20 moves the material detection sensor 21 backward, the push rod 23 moves backward, and the pressure plate 10 closes.

[0039] A tension spring is installed between the side of the secondary rack 7 and the external machine table. Under the action of the tension spring, the secondary rack 7 can quickly reset, causing the pressure plate 10 to close. The push rod 23 only makes contact with the detection mechanism but is not connected. Therefore, when the push rod 23 moves backward, the pressure plate 10 closes due to the tension of the spring.

[0040] The bottom surface of the auxiliary rack 7 of the present invention is provided with a slide rail.

[0041] The pressure plate 10 of the present invention adopts a V-shaped structure, which can effectively press down the material.

[0042] On one side of the turntable 25 of the machine tool of the present invention, a voice coil motor feeding area and a finished product area are set on one side, and a lens area is set on the other side.

[0043] The voice coil motor feeding area and the finished product area are arranged in parallel.

A finished product picking mechanism 43 is arranged between the finished product hopper 41 and the finished product tray 44. A finished product and voice coil motor transfer station 42 is arranged between the finished product tray 44 and the voice coil motor tray 33. The finished product and voice coil motor transfer station 42 is movable and located below the finished product picking mechanism 43, the voice coil motor picking mechanism 32, and the finished product and voice coil motor picking mechanism 34. The voice coil motor picking mechanism 32 is movable and located above the voice coil motor tray 33 and the finished product and voice coil motor transfer station 42.

The purpose of setting up this station is to increase the machine's product compatibility. When the product is a threaded lens or requires a rotating structure, this station can be used to replace the lens insertion height control assembly.

[0049] The testing instrument includes a light source cavity, a horizontal tube, a CCD mounting base, a corner bracket, and a vertical tube. The horizontal tube connects the light source cavity and the corner bracket horizontally. The CCD mounting base is installed in the middle of the horizontal tube, and the CCD is vertically mounted on the CCD mounting base. A reflector is installed inside the corner bracket, and a vertical tube is vertically mounted on the corner bracket. A lens and an altimeter are installed inside the vertical tube.
