Description

Technical Field

[0001] The utility model relates to the technical field of lens processing, in particular to a lens gluing device used for producing optical lenses. Background Art

[0002] A cemented lens, also known as an achromatic lens, is a type of optical lens typically made by gluing two single lenses together. Its performance in complex color imaging is significantly improved compared to a single lens. Achromatic lenses are made by gluing two lenses made of different materials together to correct for the dispersion of the glass. In the design and manufacture of optical lenses, when gluing, glue is first applied to one set of lenses, then another lens is placed on the lower lens, applying and maintaining pressure to ensure a better bond.

[0003] When gluing lenses, current lens gluing devices use telescopic rods to directly squeeze the lenses, which may cause the lenses to be damaged by excessive pressure in an instant. In addition, the pressure is controlled by the length of the telescopic rod during the pressing process. Therefore, the accuracy of the pressure applied to the lenses needs to be further improved.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1: Reference Figure 1-Figure 4 , a lens gluing device for optical lens production, comprising: a base plate 1, and also comprising: a plurality of mounting grooves 101, arranged on the base plate 1; a controller 110, fixedly arranged on one side of the base plate 1; a sealing plate 102, sealingly sliding in the mounting groove 101; a first spring 103, fixedly arranged between the sealing plate 102 and the base plate 1; a buffer airbag 104, fixedly arranged on the sealing plate 102; a film pressure sensor 105, fixedly arranged on the upper side of the buffer airbag 104; a top plate 2, arranged on the upper side of the base plate 1; a mounting assembly for mounting the top plate 2 on the base plate 1; a fixing assembly for fixing the lens, arranged on the top plate 2; a connecting pipe 113, arranged in the base plate 1; a connecting pipe 114, arranged between the connecting pipe 113 and the mounting groove 101; and a component for supplying air to the connecting pipe 113.

[0023] The air supply assembly includes an air pump 108 fixedly arranged on one side of the base plate 1. An air storage chamber 107 is provided on one side of the base plate 1. The exhaust end of the air pump 108 is connected to the air storage chamber 107. An exhaust pipe 109 is provided on one side of the air storage chamber 107.

[0024] The installation assembly includes a slide groove 201 arranged on the top plate 2, a suction cup 202 is fixedly connected in the slide groove 201, and multiple suction cups 202 are connected through an exhaust pipe 204. A vacuum pump 203 is provided on one side of the bottom plate 1, and the exhaust end of the vacuum pump 203 is connected to the exhaust pipe 204, and an air inlet pipe 205 is provided on the exhaust pipe 204.

[0025] When gluing the lenses, the corresponding lenses are placed in the mounting groove 101 and the slide groove 201 respectively, and the bottom plate 1 is located at the lower side. The controller 110 controls the vacuum pump 203 to evacuate air. At this time, the suction cup 202 fixes the lens in the slide groove 201. Then, the external glue supply mechanism supplies glue to the lens in the mounting groove 101. The top plate 2 is covered on the bottom plate 1, and the corresponding lenses are aligned. The top plate 2 is fixed to the bottom plate 1 through the fixing assembly. At this time, the lenses press the sealing plate 102 downward, and the sealing plate 102 presses the first spring 103 to cushion the lenses, thereby effectively preventing the lenses from being instantly damaged. To prevent damage caused by excessive force, the controller 110 controls the air pump 108 to supply a fixed amount of gas to the air storage chamber 107, and controls the electromagnetic valve in the connecting pipe 114 to open through the controller 110, so that the gas enters the mounting groove 101. At this time, the lower part of the sealing plate 102 is pressurized to press the lens. At the same time, the pressure on the lens is detected by the film pressure sensor 105. When the pressure reaches the set value, the controller 110 controls the electromagnetic valve in the corresponding connecting pipe 114 to close, thereby effectively ensuring the pressure on the lens and effectively preventing the lens from being damaged by excessive pressure. The gluing and pressing operation can be performed on lenses of different thicknesses.

[0026] It should be noted that solenoid valves are provided in the connecting pipe 114 , the air intake pipe 205 and the exhaust pipe 109 .

[0028] A plurality of positioning grooves 111 are provided on the bottom plate 1 , in which the electromagnetic block 112 is arranged; a limiting groove 3 is provided on the top plate 2 , in which the metal rod 301 is slidably arranged; and a second spring 302 is fixedly connected between the metal rod 301 and the limiting groove 3 .

[0029] A fitting pad 106 is detachably connected to the bottom plate 1 .

[0030] When installing the top plate 2, the two lenses are rubbed against each other by shaking the top plate 2, so that the glue between the lenses is quickly and evenly distributed. Then, the electromagnetic block 112 is energized by the controller 110, and the electromagnetic block 112 adsorbs the metal rod 301 and slides downward. At this time, the metal rod 301 slides into the limit groove 3 to limit the position of the top plate 2, thereby effectively preventing the top plate 2 from shifting.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
