Description

Technical Field

[0001] This invention relates to the field of lens mounting, and particularly to lens mounting mechanisms and mounting methods thereof. Background Technology

[0002] During lens installation, the lens mounting housing must be placed on top of the lens, and external force is used to snap the housing into place. To ensure a secure connection between the lens and the mounting housing, their centers must be aligned during installation. However, in current manual assembly processes, the lens and mounting housing are prone to misalignment, which not only affects the secure connection after assembly but also reduces installation efficiency. Summary of the Invention

[0003] The technical problem solved by this invention is to provide a lens mounting mechanism that improves lens mounting efficiency.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a lens mounting mechanism, including a base, a back plate and a left side plate and a right side plate disposed at both ends of the back plate, and an upper plate connected to the upper ends of the left side plate and the right side plate. A suction cup fixing seat is disposed on the base, a suction cup assembly is disposed at the center of the suction cup fixing seat, a middle plate is disposed above the suction cup fixing seat, a lifting drive mechanism is disposed on the upper plate, the drive end of the lifting drive mechanism is fixedly connected to the middle plate, a clamping and pressure holding mechanism is disposed on the middle plate, a pressure bar is disposed at the bottom of the middle plate, and a lens positioning assembly for positioning the lens is disposed on one side of the suction cup assembly.

[0005] Furthermore, the lens positioning assembly includes a positioning mounting bracket, on which a horizontal drive cylinder is mounted, and at the drive end of the horizontal drive cylinder is a lamp head stop.

[0006] The lamp head stop includes a suction cup seat positioning stop at the bottom for contacting the suction cup fixing seat and a lens stop at the top for positioning the lens when placing the lens.

[0007] Furthermore, the base plate is provided with a left stop block and a right stop block on both sides of the suction cup fixing seat for positioning the two sides of the lens mounting shell.

[0008] Furthermore, the clamping and pressure-holding mechanism includes a clamping cylinder fixed on the side of the middle plate. The two output ends of the clamping cylinder pass through the middle plate and extend to the lower side of the middle plate. It also includes a left clamp and a right clamp. The left clamp and the right clamp are respectively connected to the two output ends of the clamping cylinder. The opposite sides of the left clamp and the right clamp are respectively provided with arc-shaped clamping blocks adapted to the product clamping surface.

[0009] Furthermore, guide posts are provided at the four corners of the upper plate and the base, and the middle plate is slidably connected to the guide posts through guide sleeves.

[0010] Furthermore, a foolproof block is provided on the base on one side of the suction cup fixing seat. When the lens mounting shell is installed backwards, the bottom of the lens mounting shell will be blocked by the foolproof block.

[0011] Furthermore, the base is provided with a foolproof hole that mates with the lens mounting housing. When the lens mounting housing is installed accurately, the protruding end at the bottom of the lens mounting housing can extend into the foolproof hole.

[0012] Furthermore, the base is provided with a sensor mounting hole, and a distance detection sensor for detecting whether the lens mounting housing is in place is installed in the sensor mounting hole.

[0013] Furthermore, gratings are respectively provided on the symmetrical surfaces of the left and right side plates.

[0014] The present invention also discloses a lens mounting method, which employs the lens mounting mechanism described above, and the steps are as follows:

[0015] S100: The horizontal drive cylinder drives the lamp head stop block to move forward until the suction cup seat positioning stop edge contacts the suction cup fixing seat;

[0016] S200: Place the lens on the suction cup holder, with the side of the lens contacting the lens edge in the lamp holder block, and the suction cup assembly will hold the lens firmly.

[0017] S300: The horizontal drive cylinder drives the lamp head block to retract, and the lens mounting shell is placed on the lens. The lifting drive mechanism drives the middle plate to move downward, and the pressure bar contacts the lens mounting shell and presses the lens mounting shell down to engage with the lens.

[0018] S400: The clamping cylinder drives the left and right chucks to move towards the center, clamping the lens mounting housing and the lens and holding the pressure for 4-6 seconds.

[0019] S500: The clamping cylinder drives the left and right chucks to reset, and the lifting drive mechanism drives the middle plate to move upward, taking the product out of the suction cup holder.

[0020] Furthermore, in step S300, when the lens mounting shell is placed on the lens, if the lens mounting shell is placed in the wrong direction, when the lens mounting shell is placed downwards, the lens mounting shell will be blocked by the bottom anti-fooling block, and the protrusion at the bottom of the lens mounting shell cannot be inserted into the bottom anti-fooling hole. The lens mounting shell needs to be taken out and rotated 180 degrees to be reinstalled.

[0021] The beneficial effects of the present invention are:

[0022] 1. The lens positioning component in this structure ensures the correct installation position of the lens during placement, thereby guaranteeing accurate installation when installing the lens and lens mounting housing.

[0023] 2. The left and right stops in this structure enable the positioning of the lens mounting housing, thereby ensuring the accuracy of the lens and lens mounting housing assembly.

[0024] 3. The anti-misfit block in this structure can prevent the lens mounting shell from being installed backwards, thereby ensuring the accuracy of lens installation. Attached Figure Description

Detailed Implementation

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, embodiments of this application disclose a lens mounting mechanism, including a base 1, a back plate and a left side plate 2 and a right side plate 3 disposed at both ends of the back plate, and an upper plate 4 connected to the upper ends of the left side plate 2 and the right side plate 3. A suction cup fixing seat 5 is disposed on the base 1, a suction cup assembly 6 is disposed at the center of the suction cup fixing seat 5, a middle plate 7 is disposed above the suction cup fixing seat 5, a lifting drive mechanism 8 is disposed on the upper plate 4, the drive end of the lifting drive mechanism 8 is fixedly connected to the middle plate 7, and a clamping and pressure holding mechanism is disposed on the middle plate 7. A pressure bar 9 is disposed at the bottom of the middle plate 7, and a lens positioning assembly for positioning the lens is disposed on one side of the suction cup assembly 6.

[0030] Specifically, during assembly, the lens positioning assembly moves forward and then places the lens onto the suction cup holder 5, bringing the lens into contact with the lens positioning assembly. The suction cup assembly 6 then holds the lens in place. Next, the lens positioning assembly retracts, and the lens mounting shell is placed on the lens. The lifting drive mechanism 8 drives the middle plate 7 to move downward, and the pressure bar 9 contacts the lens mounting shell and presses it down to engage with the lens. Then, the clamping and pressure-holding mechanism clamps the lens mounting shell and the lens and holds the pressure for 4-6 seconds. After completion, the clamping and pressure-holding mechanism and the lifting drive mechanism 8 reset, and the operator removes the product from the suction cup holder 5.

[0031] The lens positioning component in this structure ensures the correct installation position of the lens during placement, thereby guaranteeing accurate alignment during lens and lens mounting housing installation.

[0032] In this embodiment, the lens positioning assembly includes a positioning mounting bracket 10, on which a horizontal driving cylinder 11 is provided, and at the driving end of the horizontal driving cylinder 11 is a lamp head stop block.

[0033] The lamp head block includes a suction cup positioning stop 12 located at the bottom for contacting the suction cup fixing seat 5 and a lens stop 13 located at the top for positioning the lens when placing the lens.

[0034] Specifically, when positioning the lens, the horizontal drive cylinder 11 drives the lamp head block to move forward until the suction cup seat positioning edge 12 contacts the suction cup fixing seat 5. Then, the lens is placed on the suction cup fixing seat 5, and the side of the lens contacts the lens edge 13 in the lamp head block. The suction cup assembly 6 then holds the lens firmly.

[0035] The above structure ensures that when the lamp head block moves forward, the lamp head block is in position when the suction cup seat positioning edge 12 contacts the suction cup fixing seat 5. At this time, when the lens is placed on the suction cup fixing seat 5, the side of the lens contacts the lens edge 13 in the lamp head block, which ensures the accuracy of the lens placement and thus the accuracy of subsequent assembly.

[0036] In this embodiment, the base plate is provided with a left stop 14 and a right stop 15 on both sides of the suction cup fixing seat 5 for positioning the two sides of the lens mounting shell.

[0037] Specifically, after the lens is placed, the operator puts the lens mounting shell on the lens. During the lowering process of the lens mounting shell, both ends of the lens mounting shell are restricted between the left stop 14 and the right stop 15, thereby achieving the limiting and guiding function of the lens mounting shell.

[0038] In this structure, the left stop 14 and the right stop 15 are used to position the lens mounting housing, thereby ensuring the accuracy of the lens and lens mounting housing assembly.

[0039] In this embodiment, the clamping and pressure-holding mechanism includes a clamping cylinder 16 fixed on the upper side of the middle plate 7. The two output ends of the clamping cylinder 16 pass through the middle plate 7 and extend to the lower side of the middle plate 7. It also includes a left clamp 17 and a right clamp 18. The left clamp 17 and the right clamp 18 are respectively connected to the two output ends of the clamping cylinder 16. The opposite sides of the left clamp 17 and the right clamp 18 are respectively provided with arc-shaped clamping blocks adapted to the product clamping surface.

[0040] Specifically, after the lens and lens mounting housing are pressed and snapped together, the clamping cylinder 16 drives the left chuck 17 and right chuck 18 to move towards the center and press against the side of the lens mounting housing, clamping the lens mounting housing and lens together and holding the pressure for 4-6 seconds, so that the lens and lens mounting housing are completely clamped together.

[0041] In this structure, the left clamp 17 and the right clamp 18 can be used to fully clamp the clips on both sides of the lens mounting housing to the lens. Then, a 4-6 second pressing and holding process is used to prevent the clips on both sides of the lens mounting housing from popping off the lens, thereby ensuring the firmness of the installation.

[0042] In this embodiment, guide posts 19 are respectively provided at the four corners of the upper plate 4 and the base 1, and the middle plate 7 is slidably connected to the guide posts 19 through guide sleeves.

[0043] In this structure, when the lifting drive mechanism 8 drives the middle plate 7 to move up and down, the middle plate 7 can move up and down along the guide post 19 through the guide sleeve, thus ensuring the stability of its lifting during the lifting process.

[0044] In this embodiment, a foolproof block 20 is provided on the base 1 on one side of the suction cup fixing seat 5. When the lens mounting shell is installed backwards, the bottom of the lens mounting shell will be blocked by the foolproof block 20.

[0045] The base 1 is provided with a foolproof hole 21 that cooperates with the lens mounting shell. When the lens mounting shell is installed accurately, the protruding end at the bottom of the lens mounting shell can extend into the foolproof hole 21.

[0046] Specifically, when placing the lens mounting housing, if the lens mounting housing is placed in the wrong direction, it will be blocked by the bottom anti-fooling block 20 when it is placed downwards. Furthermore, the protrusion at the bottom of the lens mounting housing cannot extend into the bottom anti-fooling hole 21. In this case, the lens mounting housing cannot be placed downwards, and it cannot be accurately fitted onto the lens. Consequently, the lens and lens mounting housing cannot proceed with the subsequent installation process. When this situation is discovered, the operator should remove the lens mounting housing, rotate it 180 degrees, and reinstall it to ensure the accuracy of the lens installation.

[0047] In this embodiment, the base 1 is provided with a sensor mounting hole, and a distance detection sensor 22 for detecting whether the lens mounting shell is placed in place is provided in the sensor mounting hole.

[0048] Specifically, when placing the lens mounting housing, if the lens mounting housing can be accurately fitted onto the lens, the distance detection sensor 22 can accurately detect the obstruction data of the lens mounting housing. At this time, the housing can smoothly proceed to the next pressing installation step. If the distance detection sensor 22 fails to detect the obstruction data of the lens mounting housing, it means that the lens mounting housing is not in place and subsequent installation operations cannot be carried out. The operator needs to adjust the lens mounting housing.

[0049] In this structure, the distance detection sensor 22 can detect whether the lens mounting shell is in place, thereby ensuring the accuracy of subsequent installation.

[0050] In this embodiment, gratings 23 are respectively provided on the symmetrical surfaces of the left side plate 2 and the right side plate 3.

[0051] Specifically, after the operator places the lens and lens mounting housing in place and removes both hands from the work area, if the grating 23 does not detect an obstruction signal, the operator can perform subsequent pressing, clamping and holding pressure operations after activating the start button. If the grating 23 detects an obstruction signal, even if the operator activates the start button, subsequent pressing, clamping and holding pressure operations cannot be performed.

[0052] The grating 23 in the above structure ensures the safety of the device during startup and prevents accidents such as hand injuries.

[0053] The present invention also discloses a lens mounting method, which employs the lens mounting mechanism described above, and the steps are as follows:

[0054] S100: The horizontal drive cylinder 11 drives the lamp head block to move forward until the suction cup seat positioning edge 12 contacts the suction cup fixing seat 5;

[0055] S200: Place the lens on the suction cup mounting base 5, with the side of the lens contacting the lens edge 13 in the lamp head block, and the suction cup assembly 6 clamps the lens.

[0056] S300: The horizontal drive cylinder 11 drives the lamp head block to retract, and puts the lens mounting shell on the lens. The lifting drive mechanism 8 drives the middle plate 7 to move downward. The pressure bar 9 contacts the lens mounting shell and presses the lens mounting shell down to engage with the lens.

[0057] S400: Clamping cylinder 16 drives left chuck 17 and right chuck 18 to move towards the middle, clamping the lens mounting housing with the lens and holding the pressure for 4-6 seconds;

[0058] S500: The clamping cylinder 16 drives the left chuck 17 and right chuck 18 to reset, and the lifting drive mechanism 8 drives the middle plate 7 to move upward, taking the product out of the suction cup fixing seat 5.

[0059] This method enables accurate installation of lenses and lens mounting housings, thereby ensuring a high yield rate for the installed products.

[0060] Specifically, in step S300, when the lens mounting shell is placed on the lens, if the lens mounting shell is placed in the wrong direction, when the lens mounting shell is placed downwards, the lens mounting shell will be blocked by the bottom anti-fooling block 20, and the protrusion at the bottom of the lens mounting shell cannot be inserted into the bottom anti-fooling hole 21. The lens mounting shell needs to be taken out and rotated 180 degrees to be reinstalled.

[0061] The above steps prevent the lens mounting housing from being placed in the wrong direction, thus ensuring the accuracy of lens installation.

[0062] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
