Description

Technical Field

[0001] The present application relates to the technical field of dispensing and mounting, and in particular, to a dispensing and mounting device. Background Art

[0002] Optical lenses need to be mounted on the barrel of a lidar. During installation, glue needs to be dispensed between the lens and the barrel to achieve fixation.

[0003] The barrel is provided with a mounting surface and a glue injection surface. The glue injection surface is located on both sides of the mounting surface. The glue injection surface is adjacent to the mounting surface and is perpendicular to the mounting surface. The mounting surface is provided with mounting holes for mounting the lens, and the glue injection surface is provided with glue dispensing grooves for fixing the lens to the barrel. The glue dispensing grooves communicate with the mounting holes. The area in the mounting hole opposite to the glue dispensing groove is the glue dispensing groove area. When mounting the lens, the lens is placed in the mounting hole, and then glue is injected into the glue dispensing groove area through a glue dispensing valve to achieve the dispensing and mounting of the lens. In the automated glue dispensing process, in order to improve the accuracy of automated glue injection, it is necessary to perform visual guidance and positioning of the position of the glue dispensing groove before glue injection through vision technology.

[0004] In the existing dispensing and mounting device, the vision mechanism and the suction component are integrated together. The vision mechanism and the suction component move synchronously in the horizontal and vertical directions. When performing dispensing and mounting, generally, the barrel is photographed and recognized on multiple sides first to locate the position of the barrel and the glue dispensing groove, and then the position information is transmitted to the suction mechanism and the glue dispensing valve. The lens is installed into the barrel through the suction component, and then the barrel equipped with the lens is conveyed to the glue dispensing operation position, and the glue dispensing groove is recognized and positioned through the vision mechanism. There are some drawbacks in this dispensing and mounting process. On the one hand, during the movement of the barrel, there may be displacement errors, which may lead to poor dispensing accuracy. On the other hand, first, the glue dispensing groove on one side is positioned by the camera, and then the position information of the glue dispensing groove obtained by the camera is transmitted to the glue dispensing valve for glue injection. In order to prevent the glue from flowing out when the barrel is flipped, it needs to be cured and then the barrel is flipped. The glue dispensing groove on the other side is positioned by the camera, and then glue is injected and cured, resulting in a complex glue injection process for the barrel and low mounting efficiency.

[0037] Example 1

[0038] Reference Figures 1-7 , a dispensing and mounting device, including a cross beam 1, a driving mechanism, a suction mechanism 2, a vision mechanism 3 and a dispensing mechanism 4. The driving mechanism is arranged on the cross beam 1, and the suction mechanism 2, the vision mechanism 3 and the dispensing mechanism 4 are all integrated on the driving mechanism. The driving mechanism controls the suction mechanism 2, the vision mechanism 3 and the dispensing mechanism 4 to move together in the horizontal plane. In this embodiment, the driving mechanism controls the suction mechanism 2, the vision mechanism 3 and the dispensing mechanism 4 to move along the X-axis direction. The suction mechanism 2, the vision mechanism 3 and the dispensing mechanism 4 can all adopt independent structures and move relative to the cross beam 1 along the Z-axis separately. The three independent structures for independently controlling the suction mechanism 2, the vision mechanism 3 and the dispensing mechanism 4 to move along the Z-axis direction are the first Z-axis driving mechanism 21, the second Z-axis driving mechanism 31 and the third Z-axis driving mechanism 41 respectively. The suction mechanism 2 is used to suck the lens and place the lens on the mounting area on the lens barrel. The vision mechanism 3 is used to identify and position the dispensing groove opened on the lens barrel and detect the lens barrel after dispensing.

[0039] As Figure 2 shown, the driving mechanism includes a mounting base 13, a driving component 11 and two guide rails 12 arranged along the Z-axis direction. The guide rails 12 are connected to the cross beam 1, and the length direction of the guide rails 12 is set along the length direction of the cross beam 1. In this embodiment, the cross beam 1 is arranged along the X-axis direction. The mounting base 13 is slidably connected to the two guide rails 12 through sliders. Multiple sliders can be arranged along the X-axis direction for each guide rail 12. The suction mechanism 2, the vision mechanism 3 and the dispensing mechanism 4 are sequentially installed on the mounting base 13 along the X-axis direction. The vision mechanism 3 is located between the suction mechanism 2 and the dispensing mechanism 4. The driving component 11 controls the mounting base 13 to move along the X-axis direction.

[0040] As Figure 3 shown, the suction mechanism 2 includes a suction component 22 and a first Z-axis driving mechanism 21. The first Z-axis driving mechanism 21 is connected to the mounting base 13. The suction component 22 is used to suck the lens. The first Z-axis driving mechanism 21 can be a motor. The first Z-axis driving mechanism 21 controls the suction component 22 to move along the Z-axis direction. After the suction component 22 sucks the lens, it moves the lens above the lens barrel through the control of the driving mechanism, and then puts the lens into the mounting hole through the first Z-axis driving mechanism 21 and keeps it under pressure for a period of time.

[0041] It should be noted that a height measuring device 5 is also provided on the first Z-axis driving mechanism 21. A steering seat is connected to the first Z-axis driving mechanism 21. The height measuring device 5 and the suction component 22 are both connected to the first Z-axis driving mechanism 21 through the steering seat. In other embodiments, the height measuring device 5 can also be arranged on the vision mechanism 3.

[0042] As shown in Figure 4 and Figure 5 shown, the vision mechanism 3 includes a second Z-axis drive mechanism 31 and a vision component 32. The second Z-axis drive mechanism 31 is used to control the vision component 32 to move along the Z-axis direction. The second Z-axis drive mechanism 31 is connected to the mounting base 13. The vision component 32 is used to take pictures of the lens barrel and the dispensing position. Specifically, in this embodiment, the lens is a lens, and the dispensing grooves for bonding the lens on the lens barrel are located on both sides of the mounting holes for mounting the lens. Therefore, the vision component 32 includes a main camera module 321 and two sub-camera modules 322. The main camera module 321 includes a main camera 3211 and a supplementary light module 3212. The supplementary light module 3212 is located below the lens of the main camera 3211. The sub-camera module 322 includes two side cameras 3221 and two imaging components. The lens axes of the main camera 3211 and the two side cameras 3221 are both arranged along the Z-axis direction. The two side cameras 3221 are arranged on both sides of the main camera 3211. The imaging components are adapted to the side cameras 3221. One imaging component corresponds to one side camera 3221. The imaging components are located below the side cameras 3221. The imaging components are used to reflect the image of the lens barrel to the lenses of the side cameras 3221.

[0043] As shown in Figure 5 and Figure 6 shown, the imaging component includes an imaging cylinder 3222, a supplementary light cylinder 3223 and a reflecting mirror 3224. The supplementary light cylinder 3223 is connected to the side of the imaging cylinder 3222 facing the axis of the main camera 3211. The supplementary light cylinder 3223 is cylindrical. The axis of the supplementary light cylinder 3223 is perpendicular to the Z-axis. A plurality of supplementary light lamps arranged in a ring are provided on the inner side wall of the supplementary light cylinder 3223. The reflecting mirror 3224 is installed in the imaging cylinder 3222. The angle between the axis of the reflecting mirror 3224 and the axis of the supplementary light cylinder 3223 is 45 degrees. A light passing hole 3225 is provided on the imaging cylinder 3222. The light passing hole 3225 is directly opposite to the lens of the side camera 3221. The light passing hole 3225 is located directly below the lens of the side camera 3221. The imaging cylinders 3222 in the two imaging components are arranged oppositely.

[0044] Specifically, the vision mechanism 3 further includes a lifting fine adjustment member 34 and a mounting block 33. The mounting block 33 is connected to the second Z-axis drive mechanism 31. The second Z-axis drive mechanism 31 can be a linear slide table controlled by a motor. The main camera 3211, the lifting fine adjustment member 34 and the imaging cylinder 3222 are all connected to the mounting block 33. There are two lifting fine adjustment members 34. The lifting fine adjustment member 34 can be a lead screw-nut structure. Manually adjust the side camera 3221. The two lifting fine adjustment members 34 are respectively arranged on both sides of the main camera 3211. The lifting fine adjustment member 34 controls the side camera 3221 to move in a direction close to or away from the imaging component to adjust the imaging focal length of the side camera 3221.

[0045] When the lens barrel is clamped on the fixture, make its mounting surface vertically upward and perpendicular to the Z-axis. The driving assembly 11 controls the main camera 3211 to confirm the position of the lens in the mounting hole relative to the mounting surface. The second Z-axis driving mechanism 31 controls the mounting block 33, the main camera 3211, and the imaging barrel 3222 to move along the Z-axis towards the lens until the lens of the main camera 3211 moves to a position directly above the lens suitable for recognition. At this time, the two imaging barrels 3222 are opposite to the dispensing grooves on both sides of the lens barrel. Then, control the two lifting fine-tuning members 34 to move along the Z-axis to adjust the distance between the lens of the side camera 3221 and the reflector 3224. The image of the dispensing groove on the side of the lens barrel enters the reflector 3224 in the horizontal direction, and the reflector 3224 reflects the image of the dispensing groove along the Z-axis into the lens of the side camera 3221. The side camera 3221 fine-tunes the focal length along the Z-axis through the lifting fine-tuning member 34 to receive a clear image.

[0046] The vision component 32 simultaneously takes pictures of the lens barrel from different directions, simultaneously identifies the positions of the two dispensing grooves and confirms the position of the lens, so that the position recognition information of the two dispensing grooves can be transmitted to the dispensing valve 43 at the same time. The dispensing valve 43 simultaneously injects glue into the two dispensing grooves, eliminating the intermediate process of flipping the lens barrel and repeating the processes of injecting glue and drying, thus improving the efficiency of glue injection.

[0047] As Figure 7 shown, the dispensing mechanism 4 includes a third Z-axis driving mechanism 41, a rotating assembly 42, and a dispensing valve 43. The third Z-axis driving mechanism 41 is connected to the mounting block 33. The third Z-axis driving mechanism 41 can be a linear slide controlled by a motor, which is used to control the dispensing valve 43 to move along the Z-axis. The rotating assembly 42 is connected to the piston rod end of the third Z-axis driving mechanism 41 through a connecting block, and the dispensing valve 43 is connected to the rotating assembly 42. In this embodiment, the dispensing valve 43 is a piezoelectric valve. During glue injection, the driving mechanism and the third Z-axis driving mechanism 41 control the dispensing valve 43 to move to the side of the dispensing groove, and the rotating assembly 42 controls the dispensing valve 43 to rotate so that the dispensing valve 43 injects glue towards the dispensing groove. After the glue injection of one side of the dispensing groove is completed, the driving mechanism and the third Z-axis driving mechanism 41 control the dispensing valve 43 to move to the side of the other dispensing groove, and the rotating assembly 42 controls the dispensing valve 43 to rotate so that the dispensing valve 43 injects glue towards the dispensing groove to complete the glue injection.

[0048] In this embodiment, the driving mechanism first moves the main camera 3211 to directly above the lens barrel, uses the main camera 3211 to identify and locate the mark points on the lens barrel, determines the deviation value between the current position of the lens barrel and the standard position. This deviation value provides guidance for adjusting the relative position between the vision component 32 and the lens barrel. According to this deviation value, the position of the vision mechanism 3 in the horizontal direction is adjusted so that the lens barrel is located exactly in the middle of the two side cameras 3221, and at the same time, it also guides the dispensing component to perform dispensing. The height measuring device 5 is moved to directly above the lens barrel to measure the current height of the lens barrel, determines the deviation value between the current height and the standard height. This deviation value provides guidance for adjusting the relative position between the vision component 32 and the lens barrel, makes the light supplement cylinder 3223 directly face the dispensing groove, and identifies the position of the dispensing groove.

[0049] The suction component 22 transfers the lens to the lens barrel and places it in the mounting hole. Then, the side cameras 3221 simultaneously take pictures and identify the position of the dispensing groove. Then, the dispensing valve 43 moves to directly above the lens barrel, and the rotation component 42 controls the rotation of the dispensing valve 43. The dispensing valve 43 injects glue into the two dispensing grooves successively. Specifically, the dispensing valve 43 first moves to one side directly above the lens barrel, then the dispensing valve 43 descends to one side of the lens barrel. The rotation component 42 controls the rotation of the dispensing valve 43 so that the dispensing valve 43 faces the dispensing groove, and the dispensing valve 43 is horizontally moved so that the glue outlet of the dispensing valve 43 extends into the dispensing groove to perform dispensing on the dispensing groove area. After completing the dispensing of one dispensing groove, the dispensing valve 43 is moved to the other side of the lens barrel. The rotation component 42 controls the rotation of the dispensing valve 43 so that the dispensing valve 43 faces the dispensing groove on this side, and the dispensing valve 43 is horizontally moved so that the glue outlet of the dispensing valve 43 extends into the dispensing groove to perform dispensing on the dispensing groove area.

[0050] After the dispensing is completed and the glue is allowed to solidify, the vision component 32 is moved to directly above the lens barrel again. The vision component 32 detects the dispensing and curing state of the lens mounted on the lens barrel to check for problems such as glue overflow. During the entire dispensing process, the positions of the lens barrel and the lens remain stationary. Through the driving mechanism, the first Z-axis driving mechanism 21, the second Z-axis driving mechanism 31, and the third Z-axis driving mechanism 41, the suction component 22, the vision component 32, and the dispensing valve 43 are controlled to move to directly above the lens barrel in sequence for operation. The suction component 22, the vision component 32, and the dispensing valve 43 can all move independently along the Z-axis direction. Thus, when performing grasping, photographing, or dispensing, other structural components will not affect the current ongoing operation, and it can also reduce the collision between the suction component 22, the dispensing valve 43 and other structures during the movement of the mounting base 13.

[0051] Embodiment 2

[0052] The combined operation mechanism in Embodiment 1 is applicable to the point-gluing of lenses to the lens barrel.

[0053] Refer toFigure 8 , different from Embodiment 1, in this embodiment, the vision mechanism 3 only includes the main lifting member and the main camera 3211. The dispensing valve 43 in this embodiment is a screw valve, and the combined operating mechanism in this embodiment is applicable to the dotting and mirror sticking of the mirror.

[0054] In this embodiment, the vision assembly 32 is moved above the lens barrel by the driving mechanism. The main camera 3211 takes pictures and identifies the positions on the lens barrel for installing the mirror and the positions where glue needs to be injected. The height measuring device 5 measures the height of the lens barrel. Then, the dispensing valve 43 is moved above the lens barrel for glue injection. Finally, the suction assembly 22 moves the mirror above the lens barrel and places the lens into the mounting hole, and keeps pressing to improve the mirror sticking effect.

[0055] In summary, in the present utility model, the positions of the main camera 3211 and the side camera 3221 are adjusted by the second Z-axis driving mechanism 31 and the lifting fine adjustment member 34 respectively. The second Z-axis driving mechanism 31 can drive the main camera 3211 and the side camera 3221 to move together. Compared with the side camera 3221 moving completely independently of the main camera 3211, the moving distance of the side camera 3221 is saved, the camera position adjustment efficiency is improved, and the cost can be saved. Two dispensing grooves are simultaneously identified by three cameras and the position of the lens is confirmed, and the detected lens barrel positioning structure is transmitted to the suction assembly 22 and the dispensing valve 43 in real time to provide visual guidance for dispensing and mounting.

[0056] During the dispensing and mounting process, the position of the lens barrel remains stationary, reducing the impact on the positioning result, improving the dispensing accuracy, and at the same time transmitting the position identification information of the two dispensing grooves to the dispensing valve 43 to improve the identification efficiency of the dispensing grooves and the lens features. The dispensing valve 43 injects glue into the two dispensing grooves at the same time, eliminating the process of turning the lens barrel in the middle and repeating the glue injection and drying process, improving the glue injection efficiency and the lens mounting accuracy.
