[0001] This utility model relates to the field of lens assembly technology, specifically a lens assembly positioning and pressing device. Background Technology

[0002] During the lens assembly process, the lens and the panel frame need to be pressed together to make the connection between the lens and the panel frame more secure. Therefore, a pressing device is required.

[0003] A Chinese patent with authorization announcement number CN219005916U discloses a lens assembly pressing device for a display lens, including a positioning platform with a positioning column fixedly mounted on the platform with a vertical central axis; the pressing mechanism includes a pressing head and a positioning cylinder, the pressing head being cylindrical and coaxial with the positioning column; the positioning cylinder being cylindrical and clearance-fitted with the positioning column; and a cylinder being drivenly connected to the pressing head. This utility model can reduce labor, avoid product damage caused by uncontrollable pressure, and improve product quality.

[0004] However, the aforementioned pressing device still has some problems. In practical applications, the tray cannot be replaced according to the shape and size of the panel frame, which will result in the inaccurate position of the panel frame inside the tray, making it impossible for the lens to be correctly installed in the center of the panel frame, thus affecting the lens assembly effect. Therefore, a lens assembly positioning pressing device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a lens assembly positioning and pressing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The lens assembly positioning and pressing device of this utility model includes a worktable, a placement plate installed on the top of the worktable, five mounting plates equally spaced on the top side of the placement plate, a mounting base installed on the top side of the mounting plate, a limiting plate I installed inside the mounting base, a groove opened inside the bottom end of the limiting plate I, a connecting plate movably installed inside the groove, a limiting plate II fixed to one end of the connecting plate, the limiting plate I and the connecting plate being installed inside the mounting base by a pin engagement, a support plate installed on the outer side of both the limiting plate I and the limiting plate II, a return spring fixed between the support plate and the mounting plate, the return spring having a small elastic coefficient, a limiting block being engaged inside the limiting plate I and the limiting plate II, and a support plate installed on the top side of the limiting block, realizing the quick replacement of a suitable support plate according to different sizes and shapes of the lens panel frame, thereby ensuring that the lens can be accurately positioned during assembly, improving pressing accuracy and work efficiency.

[0007] Preferably, five sets of four support columns are equidistantly installed on the top side of the placement plate, wherein each set of support columns is located directly below the pallet and is in contact with the pallet but not connected, providing stable support for the pallet, preventing displacement during the pressing operation, and improving the accuracy of pressing.

[0008] Preferably, the workbench has an internal cavity, a drive motor is installed on the bottom inner wall of the cavity, a sector-shaped disk is installed at the output end of the drive motor, a connecting rod is installed on the bottom side of the sector-shaped disk, a protruding rod is installed on the top side of one end of the connecting rod, a rotating shaft is rotatably installed through the workbench inside the cavity, a disc is installed on the outer side of the middle end of the rotating shaft, and four U-shaped grooves and arc-shaped grooves are respectively opened inside the disc to match the protruding rod and the sector-shaped disk. The placement plate is installed on the top side of the rotating shaft, realizing the continuous rotation of the workbench and realizing the continuous pressing operation between the lens and the panel frame.

[0009] Preferably, an L-shaped frame is installed on the top side of the workbench, a cylinder is installed on the top side of the L-shaped frame, and a pressing component is installed on the working end of the cylinder, which can adapt to panel frames of different heights.

[0010] Preferably, the pressing assembly includes a sleeve mounted on the bottom side of the actuating end of the cylinder. A compression spring is fixedly connected inside the sleeve, and a damping rod is fixedly connected to one end of the compression spring. The bottom end of the damping rod slides to the outside of the sleeve and is fixedly connected to a pressing block, which effectively reduces the impact force during pressing and protects the lens and panel frame from damage.

[0011] Preferably, a control panel is installed on one side of the workbench. The control panel is used to operate and control the electrical components inside the device, thereby realizing centralized control of the electrical components in the device.

[0012] The advantages of this utility model are:

[0013] 1. This utility model selects a suitable tray, places the limiting block above the first limiting plate and the second limiting plate, and presses the limiting block down. The first limiting plate and the second limiting plate will be squeezed outward by the limiting block. Under the action of the return spring, the support plate squeezes the first limiting plate and the second limiting plate inward to lock the limiting block. This realizes the ability to quickly change the suitable tray according to the different sizes and shapes of the lens panel frame, thereby ensuring that the lens can be accurately positioned during the assembly process and improving the pressing accuracy.

[0014] 2. The drive motor of this utility model drives the sector-shaped disk to rotate, and the protruding rod at one end of the connecting rod at the bottom of the sector-shaped disk moves accordingly. When the protruding rod enters the U-shaped groove of the disk, it pushes the disk to rotate at a certain angle. As the drive motor continues to run, the protruding rod continuously cooperates with different U-shaped grooves to realize the intermittent rotation of the disk, thereby driving the rotating shaft and the placement plate to rotate continuously. This enables the continuous pressing operation of the lens and the panel frame. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1 , 2 As shown in Figures 3 and 5, a lens assembly positioning and pressing device includes a worktable 1. A placement plate 2 is mounted on the top of the worktable 1. Five mounting plates 3 are equidistantly mounted on the top side of the placement plate 2. A mounting base 4 is mounted on the top side of the mounting plate 3. A limiting plate 5 is assembled inside the mounting base 4. A groove 6 is formed inside the bottom end of the limiting plate 5. A connecting plate 7 is movably assembled inside the groove 6. A second limiting plate 8 is fixedly connected to one end of the connecting plate 7. The limiting plate 5 and the connecting plate 7 are mounted by a pin. Inside the mounting base 4, support plates 9 are installed on the outer sides of the first limiting plate 5 and the second limiting plate 8. A return spring 10 is fixed between the support plate 9 and the mounting plate 3. The return spring 10 has a small elastic coefficient. A limiting block 11 is inserted inside the first limiting plate 5 and the second limiting plate 8. A support plate 12 is mounted on the top side of the limiting block 11. Five sets of four support columns 13 are installed at equal intervals on the top side of the placement plate 2. Each set of support columns 13 is located directly below the support plate 12 and is in contact with the support plate 12 but not connected.

[0024] An L-shaped frame 23 is mounted on the top side of the workbench 1. A cylinder 24 is mounted on the top side of the L-shaped frame 23. A pressing assembly is mounted on the working end of the cylinder 24. The pressing assembly includes a sleeve 25, which is mounted on the bottom side of the working end of the cylinder 24. A compression spring 26 is fixedly connected inside the sleeve 25. A damping rod 27 is fixedly connected to one end of the compression spring 26. The bottom end of the damping rod 27 slides to the outside of the sleeve 25 and is fixedly connected to a pressing block 28. A control panel 29 is mounted on one side of the workbench 1. In actual use, the tray 12 cannot be replaced according to the shape and size of the panel frame, which will result in the panel frame being inaccurately positioned within the tray 12. This will prevent the lens from being correctly installed in the center of the panel frame, thus affecting the lens assembly effect. First, select a suitable tray 12 according to the different sizes and shapes of the lens panel frame. Place the limiting block 11 directly above the limiting plate 5 and the limiting plate 8, and press the limiting block 11 down to make it enter the interior of the limiting plate 5 and the limiting plate 8. During this process, the first limiting plate 5 and the second limiting plate 8 will be squeezed by the limiting block 11 and open outward at a certain angle. When the limiting block 11 is fully inserted into the space between the first limiting plate 5 and the second limiting plate 8, under the action of the return spring 10, the support plate 9 will squeeze the first limiting plate 5 and the second limiting plate 8 inward. The first limiting plate 5 and the second limiting plate 8 will engage with the limiting block 11, thereby firmly fixing the tray 12 on the mounting plate 3. When removing the tray 12, pull the limiting block 11 upward to open the first limiting plate 5 and the second limiting plate 8 outward, and the limiting block 11 and the tray 12 can be removed. This allows for quick replacement of the appropriate tray 12 according to the different sizes and shapes of the lens panel frame, thereby ensuring that the lens can be accurately positioned during assembly, improving pressing accuracy and work efficiency.

[0025] The panel frame is then placed on the support plate 12, and the lens is placed inside the panel frame. The cylinder 24 is activated, and the actuating end of the cylinder 24 pushes the sleeve 25 downward. The compression spring 26 and the damping rod 27 act as a buffer. When the pressing block 28 contacts the lens and the panel frame, the compression spring 26 is compressed, which effectively reduces the impact force during pressing and protects the lens and the panel frame from damage. During the pressing operation, the support column 13 provides stable support for the support plate 12, preventing the support plate 12 from shifting and ensuring the accuracy of pressing.

[0026] Please see Figure 1 , 5As shown, the workbench 1 has an internal cavity 14. A drive motor 15 is installed on the bottom inner wall of the cavity 14. A sector-shaped disk 16 is installed at the output end of the drive motor 15. A connecting rod 17 is installed on the bottom side of the sector-shaped disk 16. A protruding rod 18 is installed on the top side of one end of the connecting rod 17. A rotating shaft 19 is rotatably installed inside the cavity 14, penetrating the workbench 1. A disc 20 is installed on the outer side of the middle end of the rotating shaft 19. The disc 20 has four U-shaped grooves 21 and arc-shaped grooves 22 inside, which are adapted to the protruding rod 18 and the sector-shaped disk 16. The placement plate 2 is installed on the top side of the rotating shaft 19. During operation, in the lens assembly process, it is necessary to press the lens and the panel frame together. To ensure a more secure connection between the lens and the panel frame, a pressing device is required. For continuous pressing operations, the drive motor 15 drives the sector disk 16 to rotate. The protrusion 18 at one end of the connecting rod 17 at the bottom of the sector disk 16 moves accordingly. When the protrusion 18 enters the U-shaped groove 21 of the disc 20, it pushes the disc 20 to rotate at a certain angle. When the sector disk 16 slides in the arc groove 22, it reduces the inertia of the disc 20 during rotation and does not affect the position of the disc 20. As the drive motor 15 continues to operate, the protrusion 18 continuously engages with different U-shaped grooves 21 to achieve intermittent rotation of the disc 20, thereby driving the rotating shaft 19 and the placement plate 2 to rotate continuously. This allows for continuous pressing operations between the lens and the panel frame.

[0027] Working principle: First, select a suitable support plate 12 according to the different size and shape of the lens panel frame, place the limiting block 11 directly above the limiting plate 5 and the limiting plate 8, and press the limiting block 11 down to make it enter the interior of the limiting plate 5 and the limiting plate 8. During this process, the first limiting plate 5 and the second limiting plate 8 will be squeezed by the limiting block 11 and open outward at a certain angle. When the limiting block 11 is fully inserted into the space between the first limiting plate 5 and the second limiting plate 8, under the action of the return spring 10, the support plate 9 will squeeze the first limiting plate 5 and the second limiting plate 8 inward. The first limiting plate 5 and the second limiting plate 8 will engage with the limiting block 11, thereby firmly fixing the tray 12 on the mounting plate 3. When removing the tray 12, pull the limiting block 11 upward to open the first limiting plate 5 and the second limiting plate 8 outward, and the limiting block 11 and the tray 12 can be removed. This allows for quick replacement of the appropriate tray 12 according to the different sizes and shapes of the lens panel frame, thereby ensuring that the lens can be accurately positioned during assembly, improving pressing accuracy and work efficiency.

[0028] The panel frame is then placed on the support plate 12, and the lens is placed inside the panel frame. The cylinder 24 is activated, and the working end of the cylinder 24 pushes the sleeve 25 downward. The compression spring 26 and the damping rod 27 play a buffering role. When the pressing block 28 contacts the lens and the panel frame, the compression spring 26 is compressed, which effectively reduces the impact force during pressing and protects the lens and the panel frame from damage. During the pressing operation, the support column 13 provides stable support for the support plate 12, prevents the support plate 12 from shifting, and ensures the accuracy of pressing.

[0029] The drive motor 15 drives the sector disk 16 to rotate, and the protruding rod 18 at one end of the connecting rod 17 at the bottom of the sector disk 16 moves accordingly. When the protruding rod 18 enters the U-shaped groove 21 of the disk 20, it pushes the disk 20 to rotate at a certain angle. When the sector disk 16 slides in the arc groove 22, it reduces the inertia of the disk 20 during rotation and does not affect the position of the disk 20. As the drive motor 15 continues to run, the protruding rod 18 continuously cooperates with different U-shaped grooves 21 to realize the intermittent rotation of the disk 20, thereby driving the rotating shaft 19 and the placement plate 2 to rotate continuously. This enables the continuous pressing operation of the lens and the panel frame.
