Embodiment Construction

[0011] A dispensing device and a dispensing method using the device will be described below with examples.

[0012] Please refer to Fig. 1, the dispensing device 100 that embodiment one provides, it comprises a first base 20, a second base 30, a first vacuum adsorption device 40, a second vacuum adsorption device 50 and a dispensing device 60.

[0013] The first base 20 includes a first base bracket 210 and a connecting rod 220 . The first base support 210 is used to support the first vacuum suction device 40 . The connecting rod 220 passes through the first base bracket 210 , and a first driving device 22 is connected to one end of the connecting rod 220 . The first driving device 22 can be moved to a certain position on the first base support 210 and fixed, which can drive the connecting rod 220 connected to it to move correspondingly relative to the first base support 210, and fix the connecting rod 220 on the first base bracket 210 . Preferably, a chute can be provided...

Abstract

The invention relates to a dispensing device, which comprises a rotary first vacuum absorption device, a second vacuum absorption device synchronously rotating along the first vacuum absorption device as well as a dispenser. The first vacuum absorption device comprises a first vacuum suction nozzle, the second vacuum absorption device comprises a second vacuum suction nozzle, the first vacuum suction nozzle is arranged relative to the second vacuum suction nozzle and then is used for fixing an awaiting dispersing optical element after coordinating with each other, and the dispenser comprises a soft coating head and is used for being abut with the edge of the fixed awaiting dispersing optical element for dispersing. The invention also relates to a dispersing method of the dispersing device, the first vacuum absorption device and the second vacuum absorption device of the dispersing device are used for fixing and rotating the awaiting dispersing optical element, meanwhile, the dispenser with the coating head is adopted to carry on dispersing, thus not only increasing coating area of bonding adhesive on the awaiting dispersing element, but also realizing uniform and stable coating of bonding adhesive on the awaiting dispersing optical element.

Description

technical field [0001] The invention relates to a glue dispensing device and a glue dispensing method using the device. Background technique [0002] A lens module applied to a camera or an optical instrument usually includes a lens mount, a lens barrel, and a plurality of optical components such as a lens group, a spacer ring, an infrared cut filter, and the like. Wherein, the lens group, the spacer ring and the infrared cut-off filter need to be sequentially fixed in the lens barrel along the direction of the optical axis. [0003] During the assembly process of the lens module, various optical components are generally fixed by a dispensing process. The dispensing process of the existing dispensing method is usually completed in the lens barrel. Taking the fixed infrared cut filter as an example, the lens group and the spacer ring are usually fixed in the lens barrel first, and then the glue is dispensed on the spacer ring by moving the dispensing needle of the dispensin...
