[0027] In another embodiment of the present invention, the upper mold structure further includes a sliding plate 8, a first guide post 6 and a second guide post 7. The first guide post 6 and the second guide post 7 are symmetrically connected to the frame 1 and are respectively located on both sides of the sliding plate 8. One side of the sliding plate 8 is slidably connected to the first guide post 6, and the other side of the sliding plate 8 is slidably connected to the second guide post 7. The pressure holding plate 21 is disposed at the bottom of the sliding plate 8.

[0028] In another embodiment of the present invention, the bottom of the pressure plate 21 is provided with a pressure block 11 protruding out. The pressure block 11 abuts against the double-sided adhesive sticker 5. The bottom of the pressure plate 21 is provided with a fourth positioning post 23, which is connected to the fourth positioning hole 22 provided on the tray 3.

[0029] In another embodiment of this utility model, the frame 1 is provided with a driving device 9, the output end of the driving device 9 is connected to the top of the sliding plate 8, and the driving device 9 drives the sliding plate 8 to move in the vertical direction.

[0030] This utility model provides a lens double-sided adhesive pressure-holding device. When assembling the device, the lower mold structure is first assembled. Multiple first locking holes 14 are provided on the base 2. The support block 16 is placed in the first locking holes 14. The first locking holes 14 are designed according to the size of the support block 16 to fix the support block 16 in the first locking holes 14. Then, the tray 3 is placed above the base 2 and positioned and fixed by the first positioning post 13. Simultaneously, a second positioning post 18, which is an elastic positioning post, is also provided on the base 2. After the tray 3 is placed, the support block 16 is engaged between the first locking holes 14 and the second locking holes 15. It should be noted that the top surface height of the support block 16 is lower than the top surface height of the tray 3; the space between the two is used to place the lens 4. A third positioning post 19 protrudes from the tray 3. When placing the double-sided adhesive sticker 5, the third positioning hole 20 is matched with the third positioning post 19 to achieve the positioning of the double-sided adhesive sticker 5. After assembling the lower mold structure, the base 2 is connected to the bearing connection of the frame 1 via the first positioning post 13, and the base 2 is installed at the operating position. The advantage of this design is that after the lens 4 and double-sided adhesive sticker 5 are paired with the lower mold structure, only the entire lower mold structure needs to be replaced during the pressure-holding operation to complete the pressure-holding operation for lenses 4 of different sizes, without requiring further structural adjustments, making the operation more flexible and convenient.

[0031] The drive device 9 is connected to the frame 1. The drive device 9 can be a cylinder or a motor. The two sides of the sliding plate 8 are respectively connected to the first guide post 6 and the second guide post 7. The first guide post 6 and the second guide post 7 are both vertically arranged. The pressure plate 21 is set at the bottom of the sliding plate 8, and the pressure block 11 protrudes from the bottom of the pressure plate 21. The pressure plate 21 needs to be set above the tray 3. The support block 16, the lens 4, the double-sided adhesive on the double-sided adhesive sticker 5, and the pressure block 11 should be located in the same vertical plane to achieve the adhesion and pressing of the double-sided adhesive. In order to make the overall matching more accurate, the fourth positioning post 23 is also set at the bottom of the pressure plate 21, which is positioned by inserting into the fourth positioning hole 22 of the tray 3. The frame 1 is also provided with a relay mounting hole 10 for installing a relay to control the operation of the device.

[0032] During production, the lens 4 is placed on top of the support block 16, in the second slot 15 of the tray 3. Then, a matching double-sided adhesive sticker 5 is taken, and the third positioning hole 20 is used to position the double-sided adhesive sticker 5 and the lens 4 against the third positioning post 19. At this time, due to the presence of the elastic second positioning post 18, the double-sided adhesive sticker 5 and the lens 4 on the support block 16 will not immediately stick together. After the lens 4 and the double-sided adhesive sticker 5 are placed, the lower mold structure is installed on the frame 1. The start button is pressed, and the drive device 9 drives the upper mold structure to press downward. When the pressure plate 21 contacts the tray 3, the tray 3 is subjected to downward force. After reaching the limit height, the lens 4 and the double-sided adhesive are stuck together. At the same time, the pressure block 11 maintains pressure on the sticking position of the double-sided adhesive and the lens 4. After the set time is reached, the drive device 9 drives the upper mold structure to move upward. The lower mold structure can be replaced to perform the pasting and pressure maintenance work again.

[0033] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
