DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] refer to Figure 1 and Figure 3 The assembly equipment of the wide-angle lens module in the embodiment of the utility model may include a stage 100, a lens carrier plate 200, a sensor pressing mechanism 300, a lens adjustment mechanism 400, a backlight plate 500 and an image driving module 600 arranged on the stage 100. The above assembly equipment can be used to assemble the wide-angle lens module, which includes a lens assembly 10 and an optical sensor 20. The lens assembly 10 includes a lens 11 and a bracket 12. The lens 11 is fixed to the bracket 12.

[0032] The lens carrier 200 is used to place the lens assembly 10 and position the lens assembly 10. Figures 1 to 3, the lens carrier plate 200 is arranged parallel to the carrier stage 100, and a positioning groove 210 with an opening at one end is provided on one side of the lens carrier plate 200, and the positioning groove 210 can be used to accommodate the lens 11, and the positioning groove 210 can penetrate the lens carrier plate 200 along the thickness direction of the lens carrier plate 200, so that when the lens 11 is located in the positioning groove 210, a part of the lens 11 can be exposed from the carrier plate surface. In addition, the opening of the positioning groove 210 is located on the side plate of the lens carrier plate 200 parallel to the thickness direction of the lens carrier plate 200, that is, when the lens assembly 10 is placed in the positioning groove 210, the lens assembly 10 can be pushed into the positioning groove 210 from the side like a drawer.

[0033] In addition, a support groove 220 for supporting the bracket 12 is provided on the side of the lens carrier 200 facing away from the carrier 100. The side wall of the support groove 220 is arranged around the positioning groove 210. When the lens 11 is placed in the positioning groove 210, the bracket 12 is located in the support groove 220. The bottom of the support groove 220 is used to support the side surface of the bracket 12 facing the lens 11. The side wall of the support groove 220 is used to abut against the side of the bracket 12, thereby positioning the lens assembly 10. Further, at least two positioning columns 221 are provided at the bottom of the support groove 220. The positioning columns 221 can be arranged corresponding to the positioning holes provided on the bracket 12. When the bracket 12 is placed in the support groove 220, the bracket 12 can be accurately positioned by the positioning columns 221 and the support groove 220. It can be understood that in the present embodiment, when the lens assembly 10 is placed on the lens carrier 200, the lens assembly 10 is in an inverted state, and the lens 11 is located on the side of the bracket 12 facing the carrier 100. At this time, although the diameter of the bracket 12 is smaller than the diameter of the lens 11, since the bracket 12 is on top, it is convenient for the operator to observe the part of the lens carrier 200 used to position the lens assembly 10, thereby making it easier to achieve precise positioning between the lens assembly 10 and the lens carrier 200.

[0034] like Figure 3 As shown, the lens carrier 200 is further provided with a positioning assembly 230, which may include a lens fastening block 231 and a driving module 232. The lens fastening block 231 is located on the side of the lens carrier 200 facing the carrier, and the lens fastening block 231 is located next to the positioning groove 210. The lens fastening block 231 is provided with an arc abutting surface. When the lens assembly 10 is placed on the lens carrier 200, the driving module 232 can drive the lens fastening block 231 to rotate, so that the arc abutting surface of the lens fastening block 231 can be directly opposite to the side of the lens 11. The outer contour of the lens 11 is circular, and the arc abutting surface can abut against the side of the lens 11, so as to cooperate with the support groove 220 to complete the positioning of the lens assembly 10 as a whole.

[0035] The driving module 232 can be fixed to the lens carrier 200. The driving module 232 can be, for example, a cylinder. One end of the lens fastening block 231 can be connected to the driving module 232, so that the driving module 232 can drive the lens fastening block 231 to rotate. The other end of the lens fastening block 231 can be connected to the lens carrier 200 through a rotating shaft, so that the lens fastening block 231 can always be connected to the lens carrier 200 and can rotate relative to the lens carrier 200. After the assembly of the lens module is completed, the lens fastening block 231 can also rotate relative to the lens carrier 200, so that the arc abutting surface is away from the lens 11, thereby facilitating the removal of the lens module.

[0036] refer to Figure 4 The sensor pressing mechanism 300 may include a first moving module 320 and a sensor pressing plate 310, wherein the sensor pressing plate 310 is located on a side of the lens carrier 200 away from the stage 100, and the sensor pressing plate 310, the lens carrier 200 and the stage 100 are arranged in sequence along a first direction, where the first direction may also be understood as a z direction. The side of the sensor pressing plate 310 facing the lens carrier 200 may be used to grab the optical sensor 20, and the first moving module 320 may be used to drive the sensor pressing plate 310 to move relative to the lens carrier 200 along the first direction, so that the sensor pressing plate 310 can be close to the lens carrier 200, and the optical sensor 20 can be attached to the lens assembly 10 positioned on the lens carrier 200.

[0037] In order to ensure that the sensor pressing plate 310 can firmly grasp the optical sensor 20 and ensure that the optical sensor 20 remains stable when moving along the first direction, illustratively, a plurality of adsorption holes (not shown in the figure) may be provided on the side of the sensor pressing plate 310 facing the lens carrier plate 200, and the plurality of adsorption holes may adsorb the optical sensor 20, so that the optical sensor 20 can be closely attached to the sensor pressing plate 310. After the optical axes of the optical sensor 20 and the lens assembly 10 are adjusted to be consistent, the adsorption force of the adsorption holes may be canceled, so that the optical sensor 20 is separated from the optical sensor 20 under the action of gravity, so as to facilitate the subsequent assembly of the optical sensor 20 and the lens assembly 10.

[0038] For reference Figure 4 and Figure 5 The backlight panel 500 is arranged between the lens carrier 200 and the platform 100, so that when the optical sensor 20 and the lens assembly 10 are attached, the lens module can capture the image of the backlight panel 500, thereby facilitating the adjustment of the optical axis between the optical sensor 20 and the lens 11 according to the captured image.

[0039] Continue to refer Figure 4 and Figure 5, a fixed carrier 800 is also connected to one side of the lens carrier 200, and the fixed carrier 800 includes a fixed carrier 810 and a cover plate 820. The fixed carrier 810 can be used to place the image driving module 600, and the image driving module 600 can include a driving circuit board body 610 and a connecting circuit board 620 for connecting with the optical sensor 20. Specifically, a fixing groove 811 is provided on the side of the fixed carrier 810 away from the carrier 100, and the fixing groove 811 is adapted to the shape of the driving circuit board body 610, so that when the driving circuit board is placed in the fixing groove 811, the fixing groove 811 can position the driving circuit board body 610. The cover plate 820 can be rotatably connected to the fixed carrier 810 relative to the fixed carrier 810. When the driving circuit board body 610 is located in the fixing groove 811, the cover plate 820 can cover the fixing groove 811, thereby fixing the driving circuit board body 610 to the fixed carrier 810. In addition, the connecting circuit board 620 extends out of the fixing groove 811 and is close to the supporting groove 220. When the optical sensor 20 is attached to the lens assembly 10, the connecting circuit board 620 can be accurately electrically connected to the optical sensor 20, so that the image driving module 600 drives the lens module to shoot.

[0040] refer to Figure 5 and Figure 6 The lens adjustment mechanism 400 is located on the side of the lens carrier 200 facing the stage 100. Specifically, the lens adjustment mechanism 400 includes two groups of adjustment modules 410, and the two groups of adjustment modules 410 are respectively connected to the opposite sides of the lens carrier 200. Each group of adjustment modules 410 includes a first adjustment module 411 and a second adjustment module 412, wherein the first adjustment module 411 can be used to drive the lens carrier 200 to move along the second direction relative to the stage 100, and the second adjustment module 412 is used to drive the lens carrier 200 to move along the third direction relative to the stage 100. The first direction, the second direction and the third direction are perpendicular to each other. Here, the second direction can also be understood as the x direction, and the third direction can be understood as the y direction.

[0041] The first adjustment module 411 may include an x ​​micrometer, and the second adjustment module 412 may include a y micrometer, so that when the first adjustment module 411 and the second adjustment module 412 adjust the position of the lens carrier 200, the position can be adjusted accurately. In this embodiment, since the lens assembly 10 and the lens carrier 200 are relatively fixed, the position of the lens assembly 10 is adjusted by adjusting the position of the lens carrier 200.

[0042] The first adjustment module 411 and the second adjustment module 412 may be stacked along the first direction, the second adjustment module 412 is located between the first adjustment module 411 and the lens carrier 200, and the lens carrier 200 is connected to the second adjustment module 412. When adjusting the position of the lens carrier 11, the first adjustment module 411 may be activated first to adjust the position of the lens carrier 200 and the second adjustment module 412 in the x direction, and then the second adjustment module 412 may be activated to adjust the position of the lens carrier 200 in the y direction, so as to achieve the position adjustment of the lens carrier 200 in the x direction and the y direction.

[0043] like Figure 6 As shown, the large wide-angle large lens module assembly equipment in this embodiment may also include a second moving module 700, which can be used to drive the lens carrier 200 to move in the horizontal direction, thereby changing the relative position of the lens carrier 200 and the sensor pressing plate 310 in the horizontal direction. It can be understood that when the lens carrier 200 is away from the sensor pressing plate 310, it is convenient for the operator to position the lens assembly 10 and the lens carrier 200, and then use the second moving module 700 to drive the lens carrier 200 to move to the bottom of the sensor pressing plate 310 to assemble the lens assembly 10 and the optical sensor 20.

[0044] Specifically, the second driving module includes a moving plate 710 and a horizontal moving module, wherein two groups of adjustment modules 410 are respectively connected to opposite ends of the moving plate 710, the backlight plate 500 is also fixedly connected to the moving plate 710, and the backlight plate 500 is located between the two groups of adjustment modules 410. The horizontal moving module is connected to the moving plate 710 to drive the moving plate 710 to move in a horizontal direction, for example, the moving plate 710 moves in a third direction. Since the lens carrier 200 is connected to the adjustment module 410, when the moving plate 710 moves relative to the carrier 100, the lens carrier 200, the adjustment module 410 and the backlight plate 500 can be driven to move synchronously.

[0045] The horizontal moving module may include a driving device 720 and two parallel guide rails 730, wherein the guide rails 730 extend along a third direction. The two groups of adjustment modules 410 may be respectively connected to the two guide rails 730 through sliders. The driving device 720 may be, for example, a translational driving cylinder. When the driving device 720 drives the moving plate 710 to move relative to the carrier 100, the adjustment module 410 may be moved along the third direction relative to the guide rails 730, thereby driving the lens carrier plate 200 to move along the third direction to directly below the sensor attachment plate 310.

[0046] In this embodiment, Figure 6As shown, the second moving module 700 may also include a buffer 740, which may be arranged on the side of the adjustment module 410 away from the moving plate 710, so as to buffer the lens carrier 200 during the movement process. Specifically, the lens carrier 200 includes a first station and a second station. The first station can be understood as a position where the lens carrier 200 is located away from the sensor pressing plate 310 and is convenient for the operator to place the lens assembly 10. The second station can be understood as a position where the lens carrier 200 is located directly below the sensor pressing plate 310, that is, the horizontal moving module can be used to drive the lens carrier 200 to move from the first station to the second station. The buffer 740 is arranged close to the second station. When the lens carrier 200 moves from the first station to the second station and approaches the second station, the buffer 740 can contact the adjustment module 410, thereby slowing down the moving speed of the lens carrier 200, so that when the driving device 720 stops working, the lens carrier 200 is just below the sensor pressing plate 310.

[0047] In some embodiments, the sensor pressing plate 310 is made of a transparent material, that is, when the operator looks down from the top of the sensor pressing plate 310, the lens assembly 10 fixed on the lens carrier 200 can be seen through the sensor pressing plate 310. The optical sensor 20 and the bracket 12 are provided with a plurality of sets of screw holes corresponding to each other. When the optical sensor 20 and the lens 11 are coaxial, the optical sensor 20 and the bracket 12 can be screwed together by screws to complete the assembly of the lens module.

[0048] Based on this, the image driving module 600 in this embodiment can also be connected to the test equipment through a connecting line. The test equipment is, for example, a computer, and the connecting line can be a USB line. After the optical sensor 20 is electrically connected to the image driving module 600, the test equipment can drive the image driving module 600 to work, thereby driving the lens module to capture the image of the backlight panel 500. The test equipment can also obtain the image captured by the lens module to determine whether the optical sensor 20 and the lens 11 are coaxial. When the two are not coaxial, the test equipment can calculate the distance that the lens 11 needs to move in the x direction and the y direction by processing the image. The operator can start the first adjustment module 411 and the second adjustment module 412 according to the calculated distance to accurately adjust the position of the lens 11 until the lens 11 and the optical sensor 20 are coaxially arranged.

[0049] In addition, reference Figure 5The sensor pressing plate 310 may also be provided with locking holes 311 corresponding to the screw holes of the optical sensor 20. The locking holes 311 penetrate the sensor pressing plate 310 along the first direction. The diameter of the locking holes 311 may be slightly larger than the diameter of the screw holes. When the optical sensor 20 is adsorbed on the sensor pressing plate 310, the screw holes of the optical sensor 20 and the locking holes 311 may be coaxially arranged in a one-to-one correspondence. After adjusting the position of the lens 11 so that the lens 11 and the optical sensor 20 are coaxial, the operator may assemble and fix the lens assembly 10 and the optical sensor 20 with screws through the locking holes 311 to ensure the assembly accuracy between the two.

[0050] refer to Figure 7 The first moving module 320 may include, for example, a pressure plate driving cylinder 321 and a pressure plate buffer cylinder 322. The pressure plate driving cylinder 321 is connected to the sensor pressing plate 310 to drive the sensor pressing plate 310 to move along the first direction. The pressure plate buffer cylinder 322 is connected to the sensor pressing plate 310. When the sensor pressing plate 310 moves toward the lens carrier 200 along the first direction, the pressure plate buffer cylinder 322 can be used to buffer the sensor pressing plate 310 when the sensor pressing plate 310 drives the optical sensor 20 to move to the point where the optical sensor 20 is about to contact the lens assembly 10, so that the optical sensor 20 can slowly approach the lens assembly 10. In this way, when the sensor pressing plate 310 attaches the optical sensor 20 to the lens assembly 10, there will be no excessive impact force. As an optional implementation scheme, when the lens carrier 200 is in the second working position, the pressure plate driving cylinder 321 drives the sensor pressing plate 310 to move toward the lens carrier 200. At the same time, the pressure plate buffer 740 moves so that the optical sensor 20 and the bracket 12 maintain a spacing of about 0.5 mm. Then, the position of the lens assembly 10 is adjusted by the first adjustment module 411 and the second adjustment module 412, and at the same time, it is observed through the transparent locking hole 311 until the screw hole of the bracket 12 and the screw hole of the optical sensor 20 are basically concentric. Then, the pressure plate driving cylinder 321 drives the optical sensor 20 toward the lens carrier 200 again until the optical sensor 20 is tightly attached to the bracket 12. At this time, it is possible to start testing whether the optical sensor 20 and the lens 11 are coaxial.

[0051] Furthermore, a pitch angle adjustment component 900 is provided on the carrier 100, and the sensor pressing mechanism 300 is arranged on the pitch angle adjustment component 900. The pitch angle adjustment component 900 can be used to adjust the pitch angle of the sensor pressing mechanism 300 relative to the carrier 100, so that the sensor pressing plate 310 and the lens carrier plate 200 can always remain parallel. When the optical sensor 20 and the lens assembly 10 are subsequently assembled, the assembly accuracy of the two can be guaranteed, thereby ensuring the good optical performance of the lens module.

[0052] In addition, the assembly equipment in this embodiment is also provided with a control box 1000, which is provided with a start button and an emergency stop button, and a program for moving each component in a certain order is preset in the control box 1000, and when the start button is pressed, each component can proceed according to the preset program. When an emergency occurs during the operation, the operator can press the emergency stop button, and unlock the emergency stop button after eliminating the fault, and then continue to work according to normal operation.

[0053] Based on the specific introduction of the large wide-angle large lens module assembly equipment in the above embodiment, when using the assembly equipment to assemble the lens module, the following steps can be referred to:

[0054] Step 1: first push the lens 11 into the positioning groove 210 along the horizontal direction, and then place the bracket 12 in the support groove 220 according to the position of the positioning column;

[0055] Step 2: Press the start button, and the driving module 232 drives the lens fastening block 231 to rotate, so that the lens fastening block 231 clamps the lens 11;

[0056] Step 3: The horizontal moving module drives the lens carrier 200 to move to the position directly below the sensor pressing plate 310;

[0057] Step 4: The pressure plate driving cylinder 321 drives the sensor pressing plate 310 to move toward the lens carrier plate 200, and starts the pressure plate buffer cylinder 322 to cooperate with the pressure plate driving cylinder 321 to align the optical sensor 20 and the bracket 12, so that the optical sensor 20 is tightly attached to the bracket 12;

[0058] Step 5: Start the image driving module 600, connect the test equipment, adjust the coaxiality between the optical sensor 20 and the lens 11 through the test equipment and the lens adjustment mechanism 400, and finally use screws to lock the bracket 12 and the optical sensor 20, and the operation is completed.
