[0001] The invention relates to a lens assembly system, in particular to a lens assembly system capable of performing heat pressing and electrification treatment on an aperture module and assembling the aperture module to a lens module. Background Art

[0002] When the lens is in use, it needs to be paired with an aperture module to adjust the amount of light entering. In the current lens assembly production line, the aperture module is assembled to the lens without powering on, and then the assembled lens is tested to check whether the aperture center of the aperture module (the center of the aperture blades) is aligned with the center of the lens (the center of the lens light hole). However, if the aperture center and the lens center are offset during the assembly process, it will affect the quality of the assembled lens. Summary of the invention

[0003] In view of this, a lens assembly system is provided herein, comprising an assembly mechanism, a turntable assembly, at least one visual assembly, a processing module and a power-on mechanism. The assembly mechanism moves between the power-on station and the assembly station. The turntable assembly has a bearing seat for rotating the bearing seat to the power-on station. The visual assembly is used to obtain a first image at the power-on station and a second image at the assembly station. The processing module is used to obtain a first drive signal, a drive position and an aperture center according to the first image, and to obtain a second drive signal and a lens center according to the second image.

[0017] In some embodiments, the lens assembly system further includes a light source module, and the light source module is located between the turntable assembly and the first camera unit.

[0018] In summary, in some embodiments, a lens assembly system transfers an aperture module placed on a carrier to a power-on station through a turntable assembly, and performs power-on movement on the aperture module through a power-on mechanism located at the power-on station to determine the aperture center of the aperture module, and then transfers the aperture module located at the power-on station to the assembly station through the assembly mechanism, and after aligning the aperture center with the lens center at the assembly station, assembles the aperture module to the lens module. Accordingly, the lens assembly system can determine the coordinates of the aperture center and the lens center before the aperture module is assembled to the lens module, thereby improving the concentricity of the assembled lens module and shortening the assembly time and detection time of the lens module.

[0088] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 . Figure 1 is a stereoscopic diagram of a lens assembly system according to some embodiments of the present invention. Figure 2 for Figure 1 The cross-sectional view along the AA direction shows the positional relationship of the power-on mechanism relative to the turntable assembly. Figure 3 A partial top view of a lens assembly system according to some embodiments of the present invention is shown, showing the positional relationship of a power supply station and a heat pressing station relative to a turntable assembly. Figure 4 This is a schematic diagram showing that the center of the aperture circle coincides with the center of the lens circle after the aperture module is assembled to the lens module according to some embodiments of the present invention. Figures 1 to 4As shown, the lens assembly system 10 includes an assembly mechanism 102, a turntable assembly 104, at least one visual component 106, a processing module 108 and an energizing mechanism 110. The assembly mechanism 102 moves between an assembly station P1 and an energizing station P2. The turntable assembly 104 has a support seat 112 for rotating the support seat 112 to an energizing station P2. The visual component 106 is used to obtain a first image at the energizing station P2 and a second image at the assembly station P1. The processing module 108 is used to obtain a first drive signal, a drive position and an aperture center C1 based on the first image, and to obtain a second drive signal and a lens center C2 (to be described later) based on the second image. The energizing mechanism 110 is located at the energizing station P2 and is used to generate an energizing motion based on the first drive signal and the drive position. After the power-on movement is completed, the assembly mechanism 102 is used to generate an assembly movement according to the second driving signal, so as to make the aperture center C1 coincide with the lens center C2 at the assembly station P1 (to be described in detail later).

[0089] In some embodiments, the lens assembly system 10 is disposed in a lens manufacturing production line, and an aperture module 20 can be assembled and fixed to a lens module 30. The lens manufacturing production line may include a loading device, a glue dispensing device, and a unloading device. In some embodiments, the lens assembly system 10 can be disposed adjacent to the glue dispensing device and the unloading device.

[0090] like Figure 4 As shown, the aperture module 20 may be, for example, a variable aperture module, wherein the aperture module 20 has a plurality of aperture blades. When the aperture module 20 is not actuated, the aperture blades are closed. After the aperture module 20 is actuated (for example, after being powered on and driven by a driver), the aperture blades will expand to form an aperture center C1. The lens module 30 may be, for example, a miniature lens (for example, a mobile phone lens module), and the lens module 30 normally exposes a lens center C2.

[0091] like Figures 1 to 4 As shown, in some embodiments, the assembly mechanism 102 can be moved to the assembly station P1 and the power-on station P2 by a slide rail assembly or a robot arm. The assembly mechanism 102 can generate an assembly motion according to a second drive signal, and generate a fixed motion according to a third drive signal (to be described later). The assembly motion can mean that after the processing module 108 obtains the aperture center C1 and the lens center C2, the assembly mechanism 102 can transfer the aperture module 20 located on the support seat 112 from the power-on station P2 to the assembly station P1 (it can mean that the assembly mechanism 102 moves the aperture module 20 located on the support seat 112 from the power-on station P2 to the assembly station P1). Figure 1 The aperture module 20 is assembled and fixed to the lens module 30 (which may refer to the assembly mechanism 102 with the lens center C2) so that the aperture center C1 and the lens center C2 can coincide with each other at the assembly station P1, and the aperture center C1 and the lens center C2 remain coincident with each other. Figure 1 The aperture module 20 is moved in the Y-axis direction to stack the aperture module 20 on the lens module 30). Figure 4 As shown, the aforementioned coincidence of the aperture center C1 and the lens center C2 may mean that the aperture center C1 coincides with an axis L coaxially arranged with the lens center C2. When the assembling mechanism 102 performs the assembling movement, the assembling mechanism 102 may assemble the aperture module 20 to the lens module 30 along the axis L to keep the aperture center C1 coincident with the lens center C2.

[0092] For example Figure 4 As shown, in some embodiments, the lens assembly system 10 further includes an assembly tray 114. The assembly tray 114 is used to place the lens module 30, wherein, before the lens module 30 is placed on the assembly tray 114, the lens module 30 may be firstly glued so that when the aperture center C1 of the aperture module 20 coincides with the lens center C2 of the lens module 30, the aperture module 20 and the lens module 30 may be bonded to each other through a bonding adhesive (e.g., a light-curing adhesive). The assembly tray 114 may be normally located at the assembly station P1, or may be manually or mechanically transported to the assembly station P1 (to be described later).

[0093] In some embodiments, Figure 2 and Figure 3 As shown, the turntable assembly 104 includes a turntable 116 and a rotating seat 118. The supporting seat 112 is connected to the turntable 116. The rotating seat 118 can generate a rotational motion after being actuated, and the rotating seat 118 can drive the turntable 116 to move to the power-on position P2, so that the supporting seat 112 can be located at the power-on position P2. In some embodiments, the turntable assembly 104 can control the rotation of the rotating seat 118 through the processing module 108 or through a control device (for example, a programmable logic controller (PLC)).

[0094] See also Figure 5 , Figure 5 for Figure 3 The partial cross-section in the BB direction shows the relative position of the aperture module in the support seat. Figure 5As shown, in some embodiments, the supporting seat 112 includes a center detection portion 120 and two wings (122, 122'), the two wings (122, 122') radially extend on both sides of the center detection portion 120, and the two wings (122, 122') have an alignment axis L1. The aperture module 20 includes an aperture body 202 and two electrical connection portions (204, 204'). When the aperture module 20 is placed on the supporting seat 112, the aperture body 202 is located at the center detection portion 120, and the two electrical connection portions (204, 204') are respectively located at the two wings (122, 122'). It should be noted that when the aperture module 20 is in the power-on position P2, the two electrical connection portions (204, 204') are substantially located on the alignment axis L1, wherein the alignment axis L1 can be a horizontal line (such as Figure 5 If the two electrical connection parts (204, 204') are not located on the alignment axis L1, the lens assembly system 10 can adjust the angles of the two electrical connection parts (204, 204') by heat pressing so that the two electrical connection parts (204, 204') are located on the alignment axis L1 (to be described in detail later).

[0095] like Figures 1 to 6 shown. Figure 6 for Figure 2 Schematic diagram of a first image captured by the first camera unit at an upward angle. Figures 1 to 6 As shown, the visual component 106 can be, for example, a camera lens. In some embodiments, the visual component 106 includes a first camera unit 124 and a second camera unit 126. The first camera unit 124 is located at the power-on station P2 and is used to obtain a first image. The second camera unit 126 is located at the assembly station P1 and is used to obtain a second image. The first image can refer to the first camera unit 124 at an upward angle (such as when the support seat 112 is located at the power-on station P2). Figure 2 The image of the aperture module 20 placed on the supporting seat 112 is captured in the positive direction of the Y axis. Figure 6 As shown, the first image may include the aperture body 202 and two electrical connection parts (204, 204') of the aperture module 20. Figure 4 As shown, the second image may refer to the second camera unit 126 at a top view angle (such as Figure 4The second image captures an image of the lens module 30 placed on the assembly tray 114 (in the negative direction of the Y axis), so the second image may include the lens body 302 of the lens module 30. The first camera unit 124 and / or the second camera unit 126 may continuously capture images (first images or second images), or a sensor may be provided at the assembly station P1 and the power-on station P2. When the sensor detects that the support base 112 on which the aperture module 20 is placed rotates to the power-on station P2, the first camera unit 124 is activated. When the sensor detects that the aperture module 20 is transferred to the assembly tray 114 of the assembly station P1, the second camera unit 126 is activated.

[0096] like Figures 1 to 6 As shown, the processing module 108 is coupled to the assembly mechanism 102, the turntable component 104, the visual component 106 and the power-on mechanism 110. The processing module 108 may be, for example, an electronic device with computing capabilities such as a computer device or a programmable logic controller, or may be a chip with computing capabilities such as a central processing unit (CPU) or a microcontroller unit (MCU). The processing module 108 may execute a processing program so that after the processing module 108 obtains the image (such as the first image or the second image) captured by the visual component 106, the processing module 108 may further calculate the coordinates of the aperture center C1, the lens center C2 and the drive position from the image, wherein the processing program may be, for example, but not limited to, a quadratic fitting circle algorithm. For example, the aperture module 20 has not yet opened the aperture before the power-on movement. At this moment, the processing module 108 may calculate the drive position (such as the first image) based on the first image. Figure 6 The driving position may refer to the coordinate positions of the two electrical connection parts (204, 204') on both sides of the aperture module 20. During the power-on movement, the aperture module 20 will open the aperture. At this moment, the processing module 108 can calculate the aperture center C1 in the first image. The aperture center C1 may refer to the area covered by the aperture center C1 (such as Figure 6The dotted circular area) or center point. When the lens module 30 is transferred to the assembly station P1, the processing module 108 at this moment can calculate the lens center C2 (which can refer to the area or center point covered by the lens center C2) from the second image. In addition, after the processing module 108 obtains the driving position, the processing module 108 can generate a first driving signal according to the coordinates of the driving position, so that the power-on mechanism 110 performs power-on movement according to the first driving signal and the driving position (the power-on movement will be described in detail later). After the processing module 108 obtains the aperture center C1 and the lens center C2, the processing module 108 can generate a second driving signal according to the coordinates of the aperture center C1 and the lens center C2, so that the assembly mechanism 102 performs assembly movement according to the second driving signal. In this way, the processing module 108 can obtain the corresponding coordinate position based on the first image and / or the second image, and the concentricity can be controlled within ±0.1mm to accurately guide the assembly mechanism 102 and / or the power-on mechanism 110 to move to the correct position.

[0097] Please refer to the combined Figures 1 to 7 . Figure 7 for Figure 1 The cross-sectional view in the AA direction shows the corresponding relationship between the assembly mechanism and the power-on mechanism at the power-on station. Figures 1 to 7 As shown, the power-on mechanism 110 can generate power-on movement after being actuated. The power-on movement may mean that when the aperture module 20 is located at the power-on position P2, after the processing module 108 calculates the driving position according to the first image, the power-on mechanism 110 moves to the driving position, and the two electrical connection parts (204, 204') of the aperture module 20 are powered, so that the aperture module 20 opens the aperture. Figure 8 , Figure 8 This is a schematic diagram of the power-on mechanism performing power-on movement when the aperture module is in the power-on position according to some embodiments of the present invention. Figure 7 and Figure 8As shown, in some embodiments, the power-on mechanism 110 includes a probe seat 128, the probe seat 128 is located on one side of the alignment axis L1, and the two sides of the probe seat 128 are respectively provided with a first probe group 130 and a second probe group 132. The power-on mechanism 110 moves according to the power-on, so that the first probe group 130 and the second probe group 132 are substantially pressed against the alignment axis L1. Specifically, the probe seat 128 can power the aperture module 20, and when the first probe group 130 and the second probe group 132 are located on the alignment axis L1, the first probe group 130 and the second probe group 132 can respectively press against the two electrical connection parts (204, 204') of the aperture module 20, so that the first probe group 130, the second probe group 132 and the two electrical connection parts (204, 204') are in an electrically conductive state, so as to actuate the aperture module 20 to open the aperture to the state closest to a circle, so as to form the aperture center C1. The power-on mechanism 110 further includes a first moving module 134 and a second moving module 136. The first moving module 134 is connected to the probe seat 128 so that the first probe group 130 and the second probe group 132 correspond to the driving positions respectively. The second moving module 136 is connected to the first moving module 134 so that the first probe group 130 and the second probe group 132 substantially abut against the alignment axis L1. The first moving module 134 and the second moving module 136 can be, for example, a motor or a cylinder push rod group. The first moving module 134 can drive the probe seat 128 to move horizontally (such as according to the first driving signal and a horizontal coordinate of the driving position). Figure 7 The second moving module 136 can drive the first moving module 134 and the probe holder 128 to move vertically (such as Figure 7 Y-axis direction).

[0098] Please refer to the combined Figures 1 to 9 , Fig. 9 for Figure 1 The cross-sectional view in the AA direction shows the corresponding relationship between the hot pressing mechanism and the hot pressing station. Figures 1 to 9As shown, in some embodiments, the lens assembly system 10 further includes a hot pressing mechanism 138. The turntable assembly 104 includes a hot pressing station P3. The hot pressing mechanism 138 is located at the hot pressing station P3 of the turntable assembly 104, and the hot pressing mechanism 138 is used to generate a hot pressing movement when the support seat 112 is located at the hot pressing station P3. In some embodiments, after the aperture module 20 is placed on the support seat 112, the support seat 112 can first rotate from the initial position to the hot pressing station P3 for hot pressing, and then rotate to the power-on station P2 for power-on detection to obtain the aperture center C1. Among them, the power-on station P2 and the hot pressing station P3 can differ by 90 degrees, that is, when the support seat 112 is located at the hot pressing station P3 and completes the hot pressing, the rotating seat 118 can drive the turntable 116 to rotate 90 degrees, so that the support seat 112 moves from the hot pressing station P3 to the power-on station P2. The hot pressing movement may mean that when the aperture module 20 is located at the hot pressing station P3, the hot pressing mechanism 138 may heat and press the two electrical connection parts (204, 204') of the aperture module 20, so that the two electrical connection parts (204, 204') are adjusted to an angle that is convenient for the first probe group 130 and the second probe group 132 to be energized after hot pressing, for example, the two electrical connection parts (204, 204') are hot pressed to the alignment axis L1.

[0099] For example Fig. 9 As shown, in some embodiments, the hot pressing mechanism 138 further includes a first hot pressing component 140, a second hot pressing component 142 and a transmission component (144, 144'). The first hot pressing component 140 is located on one side of the alignment axis L1. The second hot pressing component 142 is located on the other side of the alignment axis L1. The transmission component 144 is connected to the first hot pressing component 140, and the transmission component 144' is connected to the second hot pressing component 142. According to the hot pressing movement, the first hot pressing component 140 and the second hot pressing component 142 are driven to substantially stop at the alignment axis L1. Specifically, when the aperture module 20 is located at the hot pressing station P3, the transmission components (144, 144') respectively drive the first hot pressing component 140 and the second hot pressing component 142 to move toward each other, so that the first hot pressing component 140 and the second hot pressing component 142 stop each other at the alignment axis L1, so as to heat and press the two electrical connection parts (204, 204'). During the hot pressing process, the first hot pressing component 140 and the second hot pressing component 142 must first be heated to a default temperature, which is sufficient to heat the two electrical connection parts (204, 204') to shape them, wherein the default temperature may be, for example, 90 degrees Celsius, and the default temperature may be set according to the material characteristics of the two electrical connection parts (204, 204'), but any temperature range that can achieve hot pressing shaping can be implemented, not limited to the aforementioned temperature. Therefore, before the hot pressing process begins, the hot pressing mechanism 138 may first activate the first hot pressing component 140 and the second hot pressing component 142, so that the first hot pressing component 140 and the second hot pressing component 142 are heated to the default temperature before the hot pressing process is performed.

[0100] In some embodiments, the hot pressing movement may be that when the carrier 112 rotates to the hot pressing station P3, the hot pressing mechanism 138 directly or indirectly actuates the transmission component 144. The hot pressing mechanism 138 directly actuates the transmission component 144, which may mean that when the carrier 112 rotates to the hot pressing station P3, the hot pressing mechanism 138 immediately actuates the transmission component 144. It may also mean that when the carrier 112 rotates to the hot pressing station P3, the hot pressing mechanism 138 waits for a preset time before actuating the transmission component 144, wherein the default time may be the time for the first hot pressing component 140 and the second hot pressing component 142 to heat to a default temperature. In some embodiments, the hot pressing mechanism 138 may be provided with a sensor, which may detect that the carrier 112 rotates to the hot pressing station P3, so that the hot pressing mechanism 138 performs the hot pressing movement.

[0101] See also Fig.10 . Fig.10 for Fig. 9 The enlarged view of the middle area 9 shows that the hot pressing mechanism performs hot pressing movement on the aperture module at the hot pressing station. Fig.10 As shown, in some embodiments, one end of the first hot pressing component 140 has a first contact surface 146, and one end of the second hot pressing component 142 has a second contact surface 148. After the first contact surface 146 and the second contact surface 148 are joined, an inclined axis L2 is formed, and there is an angle between the inclined axis L2 and the alignment axis L1. Specifically, when the hot pressing mechanism 138 performs hot pressing movement and the first hot pressing component 140 and the second hot pressing component 142 are stopped at the alignment axis L1, the two electrical connection parts (204, 204') may be slightly reset due to their own elasticity and fail to reach the appropriate power-on angle. Therefore, the first hot pressing component 140 and the second hot pressing component 142 are made to stop at the alignment axis L1 through the inclined first contact surface 146 and the second contact surface 148, so that the first hot pressing component 140 and the second hot pressing component 142 are stopped at the alignment axis L1, and the two electrical connection parts (204, 204') will be bent to the angle of the inclined axis L2. After the first hot pressing component 140 and the second hot pressing component 142 are separated from the two electrical connection parts (204, 204'), the two electrical connection parts (204, 204') can be gradually shaped to an angle suitable for power supply (i.e., parallel to the alignment axis L1) through their own elasticity. In some embodiments, the angle between the tilt axis L2 and the alignment axis L1 is 10 degrees.

[0102] Please refer to the combined Figures 1 to 6 and Fig.11 . Fig.11 This is a schematic diagram of the assembly mechanism moving to a fixed position when the aperture module is powered on according to some embodiments of the present invention. Figures 1 to 6 and Fig.11As shown, in some embodiments, the visual component 106 is used to obtain a third image at the power-on station P2. The processing module 108 is used to obtain a second drive signal and a fixed position based on the third image. The assembly mechanism 102 is used to generate a fixed movement based on the second drive signal and the fixed position after the hot pressing movement is completed. When the fixed movement is completed, the power-on mechanism 110 generates a power-on movement. In some embodiments, the visual component 106 further includes a third camera unit 150. The third camera unit 150 is located at the power-on station P2 and is used to obtain a third image, wherein the third image may refer to the image of the aperture module 20 placed on the support seat 112 captured by the third camera unit 150 when the support seat 112 is located at the power-on station P2, and therefore, the third image includes the aperture body 202. The assembly movement may refer to the assembly mechanism 102 moving to a fixed position according to the second driving signal to fix and calculate the aperture module 20, so that when the power-on mechanism 110 performs the power-on movement, the electrical connection portion (204, 204') can be maintained at the alignment axis L1 and the aperture body 202 can be maintained stationary. The fixed position may refer to the position of the aperture body 202 (such as Figure 6 Therefore, when the assembly plate 114 rotates to the power-on position P2, the third camera unit 150 can generate a third image including the aperture body 202, so that the processing module 108 can obtain the second driving signal and the fixed position according to the third image.

[0103] For example Figure 8 and Fig.11 As shown, in some embodiments, the assembly mechanism 102 further includes a transfer component 152 and two pressing members (154, 154'). The transfer component 152 is located on the other side of the alignment axis L1. The transfer component 152 is used to move toward the center detection portion 120 during the fixed movement, so that the transfer component 152 can press and lift the aperture body 202. The two pressing members (154, 154') are located on both sides of the transfer component 152. The two pressing members (154, 154') are used to extend into the two wing portions (122, 122') respectively during the fixed movement, so that the two pressing members (154, 154') are substantially located on the alignment axis L1. Among them, the transfer component 152 can be, for example, a vacuum suction cup set. When the transfer component 152 performs the fixed movement, the transfer component 152 can press and fix the aperture body 202 on the supporting seat 112 (such as Fig.11As shown in FIG. 1 , when the energizing mechanism 110 completes the energizing movement and the first probe group 130 and the second probe group 132 leave the two electrical connection parts (204, 204'), the aperture module 20 can be prevented from being shaken and causing the aperture center C1 to be offset. The transfer assembly 152 can take out the aperture module 20 from the carrier seat 112 (the transfer assembly 152 can use vacuum to absorb the aperture module 20) and transfer it to the assembly plate 114 of the assembly station P1 so that the aperture module 20 can be assembled on the lens module 30. In addition, before the energizing movement starts, the two top pressing members (154, 154') will be located on the alignment axis L1. When the power-on movement begins, the first probe set 130 and the second probe set 132 will respectively press against the two electrical connection parts (204, 204'), and the two pressing members (154, 154') can stop the first probe set 130 and the second probe set 132, so that the two electrical connection parts (204, 204') are always maintained on the alignment axis L1.

[0104] For example Figure 8 As shown, in some embodiments, the two pressing members (154, 154') are separated by a first distance D1, the first probe group 130 and the second probe group 132 have a second distance D2, and the first distance D1 is substantially equal to the second distance D2. Thus, when the first probe group 130 and the second probe group 132 are respectively pressed against the two electrical connection parts (204, 204'), the pressing member 154 and the first probe group 130 may correspond to a plumb line L3, and the pressing member 154' and the second probe group 132 may correspond to a plumb line L3'. Thus, when the first probe group 130 and the second probe group 132 push against the two electrical connection parts (204, 204'), the first probe group 130 and the second probe group 132 may be prevented from being misaligned with the two pressing members (154, 154') respectively, thereby causing the two electrical connection parts (204, 204') to bend. It should be noted that the top pressing member (154, 154') corresponds to the plumb line (L3, L3'), which may mean that the first probe group 130 and the second probe group 132 are parallel to the plumb line (L3, L3'), and the plumb line (L3, L3') passes through the top pressing member (154, 154'), the first probe group 130 or the second probe group 132. In some embodiments, the probe seat 128 has an array of the first probe group 130 and an array of the second probe group 132, and the array of the first probe group 130 and the array of the second probe group 132 are respectively arranged in an array or staggered on the probe seat 128. Accordingly, when the array first probe group 130 and the array second probe group 132 move to the driving position, even if any group of the first probe group 130 or any group of the second probe group 132 does not directly contact the two electrical connection parts (204, 204'), other first probe groups 130 or other second probe groups 132 can still contact the two electrical connection parts (204, 204') to ensure that the probe seat 128 can smoothly power on the aperture module 20.

[0105] Please refer to the combined Figure 1 , Figure 3 and Fig.12 . Fig.12 This is a schematic diagram of the material picking mechanism performing material picking movement when the aperture module is located at the material picking station according to some embodiments of the present invention. Figure 1 , Figure 3 and Fig.12 As shown, in some embodiments, the lens assembly system 10 further includes a material picking mechanism 156. The material picking mechanism 156 moves a material picking station P4 and a supporting base 112. The visual component 106 is used to obtain a fourth image at the material picking station P4. The processing module 108 is used to obtain a third drive signal and a material picking position based on the fourth image. The material picking mechanism 156 is used to generate a material picking movement based on the third drive signal and the material picking position. In some embodiments, the lens assembly system 10 further includes a material tray 158, and the material tray 158 is located at the material picking station P4. The visual component 106 further includes a fourth camera unit 160. The fourth camera unit 160 is located at the material picking station P4 and is used to obtain a fourth image. Among them, the fourth image may refer to the fourth camera unit 160 at a top view angle (such as when the material tray 158 is located at the material picking station P4). Fig.12 The fourth image may include the aperture body 202 and the two electrical connection parts (204, 204'). The material picking position may refer to the coordinate position of the aperture body 202 placed on the material holding tray 158 when the aperture module 20 is placed on the material holding tray 158. The material picking movement may refer to that after the processing module 108 obtains the material picking position according to the fourth image, the material picking mechanism 156 transfers the aperture module 20 from the material holding tray 158 to the supporting seat 112.

[0106] For example Figure 3 As shown, in some embodiments, the turntable assembly 104 is provided with a plurality of bearing seats (112, 112a, 112b). When the material taking mechanism 156 transfers the aperture module 20 from the material receiving tray 158 to the bearing seat 112, the turntable assembly 104 sequentially rotates the bearing seat 112 to the hot pressing station P3 and the power supply station P2. Figure 3 As shown in , when the turntable assembly 104 rotates once, the carrier 112 will rotate to the hot pressing station P3, and the carrier 112a will rotate to the assembly station P1. At this moment, the assembly mechanism 102 has transferred the aperture module 20 of the carrier 112b to the assembly plate 114 and will leave the power-on station P2. When rotating for the next time, the material taking mechanism 156 can transfer the aperture module 20 of the material tray 158 to the carrier 112b and rotate the carrier 112b to the hot pressing station P3. With the aforementioned cyclic operation, the lens assembly system 10 can meet the continuous operation requirements of the production line under the coordination of the operation sequence of each station.

[0107] See also Fig.13 , Fig.13 for Figure 1 The cross-sectional view in the AA direction shows a schematic diagram of the conveying mechanism performing a conveying motion to convey the lens module to the assembly station. Fig.13 As shown, the lens assembly system 10 further includes a conveying mechanism 162 and a sensor group 164. The sensor group 164 is used to generate a first start signal at one end of the conveying mechanism 162 (which can be determined according to the direction of the production line), and to generate a first end signal at the assembly station P1. The conveying mechanism 162 is used to generate a conveying movement according to the first start signal, and to stop the conveying movement according to the first end signal. Among them, the conveying mechanism 162 can be, for example, a roller group, a track group or a conveyor belt. The sensor group 164 can be, for example, an optical sensor or an ultrasonic sensor. In some embodiments, the two ends of the conveying mechanism 162 can be connected to the dispensing equipment and the unloading equipment respectively. After the dispensing equipment applies the photocuring glue to all the lens modules 30 on the assembly tray 114, the assembly tray 114 can be conveyed to the lens assembly system 10 through the conveying mechanism 162, and the aperture module 20 is assembled on the lens module 30 at the assembly station P1. Furthermore, after the assembly mechanism 102 completes the assembly of all the lens modules 30 in the assembly tray 114 , the conveying mechanism 162 can perform a conveying movement again to convey the assembly tray 114 to the unloading device.

[0108] For example Fig.13As shown, in some embodiments, the sensor group 164 may include a first sensor 166 and a second sensor 168. The first sensor 166 is located at one end of the conveying mechanism 162 and is used to generate a first start signal. The second sensor 168 is located at the assembly station P1 and is used to generate a first end signal. The conveying movement may refer to that when the first sensor 166 senses that the assembly tray 114 is placed on the conveying mechanism 162, the first sensor 166 may generate a first start signal, so that the conveying mechanism 162 conveys the assembly tray 114 to the assembly station P1. When the second sensor 168 senses that the assembly tray 114 is located at the assembly station P1, the second sensor 168 may generate a first end signal, so that the conveying mechanism 162 pauses conveying the assembly tray 114 and stops the conveying mechanism 162 at the assembly station P1. In some embodiments, when the assembly mechanism 102 completes the assembly of all lens modules 30 in the assembly tray 114, the conveying mechanism 162 performs the conveying movement again. For example, when the assembly tray 114 is located at the assembly station P1 and the conveying mechanism 162 suspends the conveying movement, the conveying mechanism 162 can count through a counter, and when the count reaches an assembly time, the conveying mechanism 162 performs the conveying movement again, wherein the assembly time can refer to the time when the assembly mechanism 102 completes the assembly of all the lens modules 30. Alternatively, after the assembly mechanism 102 completes the assembly of all the lens modules 30, the assembly tray 114 is manually removed from the assembly station P1. Alternatively, when the processing module 108 determines that all the lens modules 30 have been assembled according to the first image, the processing module 108 actuates the conveying mechanism 162 to resume the conveying movement.

[0109] For example Figure 4 As shown, in some embodiments, the assembly mechanism 102 further includes an ultraviolet light module 170, and the ultraviolet light module 170 is located on both sides of the transfer component 152. When the transfer component 152 makes the aperture circle center C1 and the lens circle center C2 coincide with each other, the transfer component 152 can assemble the aperture module 20 to the lens module 30. At this time, the assembly mechanism 102 can actuate the ultraviolet light module 170, so that the ultraviolet light module 170 irradiates an ultraviolet light source on the photocuring adhesive, so that the photocuring adhesive can be solidified, thereby fixing the aperture module 20 to the lens module 30.

[0110] For example Figure 2As shown, in some embodiments, the lens assembly system 10 further includes a light source module 172, and the light source module 172 is located between the turntable assembly 104 and the first camera unit 124. When the first camera unit 124 captures the first image, the light source module 172 can be activated to generate an auxiliary light source, so that the first camera unit 124 can still capture a clear first image through the illumination of the auxiliary light source in a low light environment, so that the processing module 108 can accurately calculate the aperture body 202 and the two electrical connection parts (204, 204'). In some embodiments, the lens assembly system 10 can also be equipped with an additional light source module 172, and each light source module 172 is respectively connected to the second camera unit 126, the third camera unit 150 and / or the fourth camera unit 160 to assist the aforementioned camera units (124, 126, 150, 160) in capturing images.

[0111] In summary, in some embodiments, a lens assembly system 10 transfers an aperture module 20 placed on a supporting seat 112 to a power-on station P2 through a turntable assembly 104, and performs power-on movement on the aperture module 20 through a power-on mechanism 110 located at the power-on station P2 to determine the aperture center C1 of the aperture module 20, and then transfers the aperture module 20 located at the power-on station P2 to the assembly station P1 through the assembly mechanism 102, and after the aperture center C1 is aligned with the lens center C2 at the assembly station P1, the aperture module 20 is assembled to the lens module 30.
