Technical Field

[0001] This utility model belongs to the field of lens mounting technology, and in particular relates to a lens mounting mechanism using frame-shaped adhesive tape. Background Technology

[0002] However, existing mechanisms for attaching lenses to electronic devices using frame-type adhesive tape suffer from potential misalignment during the installation of the upper and lower molds. This affects the accuracy of the installed molds, prolonging the assembly time between the PC lens adhesive and the outer frame, thus impacting the device's production efficiency and increasing costs. In other words, traditional frame-type adhesive tape mechanisms for attaching lenses are difficult to install correctly, consequently affecting production efficiency and increasing costs. Utility Model Content

[0003] This invention addresses the problem in existing technologies where traditional frame-type adhesive tape lens-attaching mechanisms are difficult to install between the upper and lower molds, thus affecting production efficiency and increasing production costs. The following technical solution is proposed:

[0004] A lens-attaching mechanism using frame-shaped adhesive tape includes:

[0005] The upper mold is used to place the adhesive backing of the PC lens to be bonded;

[0006] The lower mold is used to hold the outer frame;

[0007] The positioning component includes a positioning post and a limiting block. The positioning post is connected to the upper mold and is located at the center of the upper mold. The limiting block is connected to the lower mold and is located at the edge of the lower mold. Through the cooperation between the positioning post and the limiting block, the upper mold and the lower mold are vertically aligned.

[0008] As a preferred embodiment of the above technical solution, it also includes:

[0009] A baffle plate is connected to the upper mold, and the baffle plate is located below the limiting block;

[0010] An elastic sheet is connected to the baffle and the upper mold at the middle position, and is used to prevent the end face of the baffle near the elastic sheet from fitting with the upper mold;

[0011] Transmission pipe one is connected to the upper mold, with one end of the transmission pipe one located below the baffle and the other end equipped with a three-way valve;

[0012] Transmission pipe two, one end of which is connected to the three-way valve, and the other end of the transmission pipe two is provided with a chamber;

[0013] An air outlet pipe is connected to the chamber, and a movable rod is provided inside the air outlet pipe. The movable rod is bonded to the adhesive backing of the PC lens.

[0015] As a preferred embodiment of the above technical solution, the upper mold is provided with multiple air vents, and the multiple air vents are arranged in a rectangular pattern around the area where the PC lens backing adhesive is placed, so as to allow air to circulate around and inside the upper mold.

[0016] As a preferred embodiment of the above technical solution, the surface of the movable rod is in contact with the inner wall of the air outlet pipe, and the movable rod is provided with a protrusion located below the movable rod to limit the movement distance of the movable rod.

[0028] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] Example 1: This utility model provides a lens-attaching mechanism using frame-shaped adhesive tape, such as... Figures 1 to 6 As shown, the device includes: an upper mold 1, a lower mold 2, and a positioning assembly. The upper mold 1 has a groove on its surface the same size as the PC lens adhesive, used to place the PC lens adhesive to be pasted onto the product surface inside the groove. The lower mold 2 has a rectangular groove inside its interior, the same size as the outer frame, used to place the outer frame to be processed inside the rectangular groove. The positioning assembly includes positioning pins 3 and limiting blocks 4. The positioning pins 3 are connected to the upper mold 1 and are located at the center of the upper mold 1. There are four positioning pins 3, evenly distributed on both sides of the groove. The lower mold 2 has a positioning groove on its surface at the corresponding position of the positioning pin 3, identical to the positioning pin 3. The opening of the positioning groove has a large diameter. The positioning pin 3 fits into the positioning groove. The limiting block 4 is connected to the lower mold 2 and is located at the edge of the lower mold 2. Through the cooperation between the positioning pin 3 and the limiting block 4, the upper mold 1 and the lower mold 2 are vertically aligned. There are four limiting blocks 4, which are evenly distributed at the four corners of the lower mold 2. The upper mold 1 has a limiting groove at the position of the limiting block 4. The limiting block 4 is slidably connected to the inside of the limiting groove. The upper mold 1 has multiple air vents that run through the upper mold 1 and are arranged in a rectangular pattern around the area where the PC lens backing is placed, so that air can circulate around and inside the upper mold 1.

[0030] The positioning column 3 and the limiting block 4 are used to position the upper mold 1 and the lower mold 2, making the installed upper mold 1 and lower mold 2 more accurate. This avoids the problem that the PC lens adhesive pasted on the outer frame surface will shift when the upper mold 1 and lower mold 2 have slight offsets, thus affecting the production quality of the device.

[0031] In use, the PC lens adhesive is first fixed to the surface of the upper mold 1, and then the outer frame is fixed to the surface of the lower mold 2. The operator then moves the upper mold 1 to a position above the lower mold 2, ensuring that the positioning post 3 and positioning groove are vertically aligned with the limiting block 4 and limiting groove. Next, the operator lowers the upper mold 1, causing the PC lens adhesive and positioning post 3 to move down simultaneously. When the positioning post 3 reaches the inside of the positioning groove, the positioning groove positions the upper mold 1, ensuring that the limiting block 4 is positioned exactly inside the limiting groove. This completes the installation process of the upper mold 1 and lower mold 2. The positioning post 3 and limiting block 4 work together to position the upper mold 1 and lower mold 2, making the installed upper mold 1 and lower mold 2 more precise. This avoids the problem of slight misalignment of the upper mold 1 and lower mold 2 causing the PC lens adhesive to shift on the outer frame surface, thus improving the production quality of the device.

[0032] Specifically, the lower mold 2 is snapped to the bottom of the upper mold 1, and a positioning post 3 is fixedly connected to the middle of the bottom of the upper mold 1. The positioning post 3 is slidably connected to the inside of the lower mold 2, and a limit block 4 is fixedly connected to the top edge of the lower mold 2. The limit block 4 is slidably connected to the inside of the upper mold 1.

[0033] To achieve a more stable connection between the PC lens adhesive and the frame, as shown in the above example, the following solution is proposed: Figures 4 to 6 As shown, a lens-attaching mechanism using frame-shaped adhesive tape further includes: a baffle 5, an elastic sheet 6, a first transmission pipe 7, a second transmission pipe 9, and an air outlet pipe 11. The baffle 5 is connected to the upper mold 1 and slidably connected inside the limiting groove. The baffle 5 is located below the limiting block 4. The elastic sheet 6 is connected between the baffle 5 and the middle of the upper mold 1. The elastic sheet 6 is configured as a spring to prevent the end face of the baffle 5 near the elastic sheet 6 from sticking to the upper mold 1. The first transmission pipe 7 is connected to the upper mold 1 and embedded inside the upper mold 1. One end of the first transmission pipe 7 is located below the baffle 5. A vent pipe 11 is provided at the edge of the limiting groove. A blocking block is provided to limit the movement distance of the baffle 5. A three-way valve 8 is provided at the other end of the transmission pipe 7. One end of the transmission pipe 9 is connected to the three-way valve 8, and the other end of the transmission pipe 9 is provided with a chamber 10. An air outlet pipe 11 is connected to the chamber 10. A moving rod 12 is provided inside the air outlet pipe 11. The moving rod 12 is bonded to the back of the PC lens with adhesive. The surface of the moving rod 12 is bonded to the inner wall of the air outlet pipe 11. The moving rod 12 is provided with a protrusion located below the moving rod 12 to limit the movement distance of the moving rod 12. The number of air outlet pipes 11 is set to multiple, and the air outlet pipes 11 are located at the edge of the chamber 10.

[0034] During the installation process of the upper mold 1 and the lower mold 2, the PC lens adhesive is pushed down, making the PC lens adhesive and the outer frame more tightly installed. This avoids the problem of the PC lens adhesive and the outer frame easily separating after installation if there are impurities on the surface of the upper mold 1 or the lower mold 2, thus improving the stability of the PC lens adhesive and the outer frame after installation.

[0035] During use, when the limiting block 4 slides inside the limiting groove, it pushes the baffle 5 towards the elastic sheet 6 and squeezes the elastic sheet 6, causing it to deform. During this movement, the baffle 5 draws gas from inside the limiting groove into the first transmission pipe 7. Then, the air from the two horizontal transmission pipes 7 enters the second transmission pipe 9 through the same three-way valve 8. This gas then travels along the second transmission pipe 9 into the chamber 10, and through the chamber 10, it is evenly distributed to multiple outlet pipes 11, pushing... The movable rod 12 slides inside the air outlet pipe 11. When the movable rod 12 moves, it pushes the PC lens adhesive towards the outer frame, so that the movable rod 12 can assist in the installation process of the PC lens adhesive and the outer frame. During the installation process of the upper mold 1 and the lower mold 2, the PC lens adhesive is pushed down, so that the PC lens adhesive and the outer frame are installed more tightly. This avoids the problem that the PC lens adhesive and the outer frame are prone to separation when there are impurities on the surface of the upper mold 1 or the lower mold 2, thereby improving the stability of the PC lens adhesive and the outer frame after installation.

[0036] Specifically, baffle 5 is slidably connected to the inside of upper mold 1. One end face of baffle 5 is fixedly connected to elastic sheet 6, and the other end face of elastic sheet 6 is fixedly connected to the inside of upper mold 1. A transmission pipe 7 is provided below baffle 5. Transmission pipe 7 is embedded in the inside of upper mold 1. The other ends of the two horizontal transmission pipes 7 are each sleeved with the same three-way valve 8. Transmission pipe 9 is embedded in the three-way valve 8. The other end of transmission pipe 9 is embedded in the chamber 10. An air outlet pipe 11 is fixedly connected to one end face of chamber 10. A moving rod 12 is slidably connected inside the air outlet pipe 11.

[0037] Working Principle: In use, the PC lens adhesive is first fixed to the surface of the upper mold 1, and then the outer frame is fixed to the surface of the lower mold 2. The operator then moves the upper mold 1 above the lower mold 2, aligning the positioning post 3 and positioning groove vertically with the limiting block 4 and limiting groove. The operator then lowers the upper mold 1, causing the PC lens adhesive, limiting groove, and positioning post 3 to move downwards simultaneously. When the positioning post 3 is inside the positioning groove, the limiting groove fits perfectly onto the outer surface of the limiting block 4. At this point, the limiting block 4 pushes the baffle 5 inside the limiting groove towards the elastic sheet 6, compressing the elastic sheet 6 and causing it to deform. During this movement, the baffle 5 draws gas from inside the limiting groove into the transmission pipe 7. The air in the two horizontal transmission pipes 7 then flows through... The gas enters the transmission pipe 2 9 through the same three-way valve 8, and then enters the chamber 10 along the transmission pipe 2 9. The gas is then evenly distributed to multiple outlet pipes 11 through the chamber 10, pushing the moving rod 12 to slide inside the outlet pipe 11. When the moving rod 12 moves, it pushes the PC lens adhesive towards the outer frame, so that the moving rod 12 can assist the installation process of the PC lens adhesive and the outer frame. Finally, the above steps are reversed to separate the upper mold 1 and the lower mold 2. During the installation process of the upper mold 1 and the lower mold 2, the PC lens adhesive is pushed down, so that the PC lens adhesive and the outer frame are installed more tightly. This avoids the problem of the PC lens adhesive and the outer frame easily separating when there are impurities on the surface of the upper mold 1 or the lower mold 2, thereby improving the stability of the PC lens adhesive and the outer frame after installation.

[0038] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
