Description

Technical Field

[0001] The utility model relates to the field of lens processing, and more specifically, to a clamping and fixing structure for molded lens coating. Background Art

[0002] When the lens is processed, the surface of the mirror needs to be coated in advance to improve the corresponding properties of the mirror, such as anti-fog, anti-fouling, and wear resistance.

[0003] When processing existing lenses, most of them adopt a point-to-point clamping method of "one hole, one lens", that is, a number of clamping holes are opened in the mold, and the corresponding lenses are placed in the corresponding holes. The number of lenses is equivalent to the number of holes. Although this method can improve the stability of lens clamping, it takes extra time to operate each time the lens is replaced. The reason is that the "one hole, one lens" mold requires relatively independent clamping parts and a large number of them. Utility Model Content

[0028] The utility model provides Figure 1-Figure 7 The clamping and fixing structure for coating molded lenses shown in the figure mainly includes a bearing mechanism 1, a clamping mechanism 2 and a threaded column 3. The bearing mechanism 1 mainly bears the lens, the clamping mechanism 2 clamps the lens in the bearing mechanism 1, and the threaded column 3 is used to drive the clamping mechanism 2 to clamp the lens in time.

[0029] Example 1

[0030] One configuration of the supporting mechanism 1 is as follows: it includes a supporting plate 11, side clamps 12 and a baffle 13. The supporting plate 11 is a disc-shaped body. A baffle 13 is fixed to the outer edge of the supporting plate 11 to prevent the lens from falling off the supporting plate 11 when clamped by the clamping mechanism 2. A plurality of pairs of side clamps 12 are fixed on the supporting plate 11. A placement groove for placing the lens is formed between each pair of side clamps 12. The placement groove can be set to a fixed width or a gradually changing width.

[0031] Among them, a hollow shell 14 is set between the two placement grooves, and the shell 14 is fixed on the supporting plate 11. A hose is used to connect the shell 14 and the external fan. Absorption holes are opened on the side wall of the shell 14 and the corresponding side clamping plate 12. The negative pressure of the fan can absorb the excess coating material sprayed on the lens, thereby reducing the pollution of the coating material to the entire structure.

[0032] Another arrangement of the supporting mechanism 1 is as follows: it includes a supporting plate 11, side clamps 12, baffles 13, locking pins 15 and a rotating shaft 16. The supporting plate 11 is a disc-shaped body. A baffle 13 is fixed at the outer edge of the supporting plate 11 to prevent the lens from falling off the supporting plate 11 when it is pushed and clamped by the clamping mechanism 2. A plurality of rotating shafts 16 are fixed on the supporting plate 11. Each rotating shaft 16 is rotatably connected to two side clamps 12 with telescopic capability. The side clamps 12 include a telescopic section 1 and a telescopic section 2. The telescopic section 1 is used for being rotatably connected to the rotating shaft 16. The telescopic section 2 is provided with a card slot for being slidably connected to the baffle 13. The telescopic section 1 and the telescopic section 2 can slide relative to each other. In this way, when the side clamps 12 rotate around the rotating shaft 16, the slot width of the placement slot can be changed, thereby improving the adjustment flexibility of the slot width of the placement slot.

[0033] Furthermore, a locking pin 15 is fixed on the end of the telescopic section 2, and the locking pin 15 passes through the limiting groove provided on the supporting plate 11. By utilizing the threaded connection between the locking pin 15 and the locking nut located on both sides of the limiting groove, the position of the side clamp 12 can be temporarily fixed, thereby improving the stability of the placement slot during use.

[0034] Example 2

[0035] Based on any one of the configuration structures of the supporting mechanism 1 in Embodiment 1, the following three configuration modes of the clamping mechanism 2 are also provided.

[0036] Specifically, the clamping mechanism 2 includes a support block 21, a cavity 22, a top block 23 and a clamping block 24. The support block 21 is placed at the center of the supporting plate 11. A cavity 22 is opened in the support block 21. The bottom of the cavity 22 is slidably connected to the top block 23. The side of the cavity 22 is slidably connected to the clamping block 24. The clamping block 24 slides along the extension direction of the corresponding placement groove. When the top block 23 moves upward, the clamping block 24 extends outward.

[0037] A driving member with up and down movement characteristics is arranged below the carrier plate 11, which is a threaded column 3. The threaded column 3 is transmission-connected to an internal thread opened at the center of the carrier plate 11. The threaded column 3 is fixedly connected to an output shaft of a motor. The motor is installed in the coating machine. A controller electrically connected to the motor is also arranged in the coating machine for controlling the operation of the motor after receiving instructions.

[0038] One structure: both the top block 23 and the clamping block 24 are wedge-shaped blocks. There is no specially set medium in the cavity 22. The motor is used to drive the threaded column 3 to rotate and move upward. The threaded column 3 moves upward by squeezing the top block 23. The squeezing and pushing effect between the wedge-shaped blocks is used to push the corresponding clamping block 24 to move outward, so that the clamping block 24 pushes the lens in the corresponding placement groove onto the baffle 13 on the corresponding side. The clamping effect between the baffle 13 and the clamping block 24 is used to improve the clamping stability of the lens.

[0039] Another structure is as follows: the cavity 22 is filled with liquid medium, the top block 23 moves upward in contact with the inner wall of the cavity 22, and the clamping block 24 is in airtight sliding connection with the cavity 22. The so-called liquid medium can be compressed oil, etc. By utilizing the pressure transmission effect of the medium, when the top block 23 squeezes the oil, the oil will transmit force to the clamping block 24, thereby achieving the purpose of pushing out the clamping block 24, so that the clamping block 24 pushes the lens in the corresponding placement groove to the baffle 13 on the corresponding side, and utilizes the clamping effect between the baffle 13 and the clamping block 24 to improve the clamping stability of the lens.

[0040] There is another structure: a plurality of electric cylinders, a control module and a pressure sensor are installed in the cavity 22, the cylinder seat of the electric cylinder is fixedly connected to the side wall of the cavity 22, and the telescopic end of the electric cylinder is fixedly connected to the clamping block 24, the pressure sensor is fixed to the bottom of the top block 23, and the pressure sensor is located on the upward movement path of the threaded column 3, the pressure sensor, the electric cylinder and the control module are electrically connected, and when the pressure sensor is pressurized, the control module controls the telescopic end of the electric cylinder to extend. Under this structure, according to the pressure of the threaded column 3 on the pressure sensor, the pressure signal is converted into an electrical signal and transmitted to the electric cylinder through the data processing function of the control module, and then the control unit in the electric cylinder controls the telescopic end to drive the clamping block 24 to extend, so as to achieve the purpose of clamping the lens.

[0041] It should be noted that, in this structure, the pressure applied to the pressure sensor is positively correlated with the extension distance of the telescopic end of the electric cylinder. The greater the pressure applied to the pressure sensor, the greater the extension distance of the telescopic end of the clamping block 24.

[0042] It should be noted that the electric cylinder includes a cylinder base, a telescopic end and a control unit. The cylinder base and the telescopic end are slidably connected. The control unit installed in the cylinder base is electrically connected to the control module in the cavity 22 for controlling the extension time and length of the telescopic end.

[0043] In the above embodiment, more lenses can be placed by changing the length of the placement groove at the beginning of the setting.

[0044] In summary, the technical solution of the utility model can be summarized as follows: by changing the width of the placement groove, lenses of different sizes can be placed in the groove, or multiple lenses of the same size can be placed in the groove, and the extrusion between the lenses can be utilized to reduce the number of clamping parts while still ensuring the stability of the clamping.

[0045] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
