Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a hot melting device for assembling an optical lens. Background Art

[0002] The role of hot melt processing in optical lens assembly is mainly reflected in the following aspects:

[0003] Welding or connection: The hot melt process heats the material to the melting point and fuses it to achieve welding or connection between the components of the optical lens. This connection method has high strength and stability, which can effectively ensure the performance and life of the optical lens;

[0004] Improve production efficiency: The adhesive curing process in hot melt processing can be carried out in parallel with the pre-positioning and active calibration process, without the need to perform these processes in sequence. This greatly shortens the production cycle and improves production efficiency;

[0005] Improved optical performance: During the hot melt process, the reactive hot melt adhesive melts at high temperature and becomes liquid before being applied to the lens components. Since the hot melt adhesive no longer needs to be baked for further curing (the bonding strength is sufficient), the variation in optical performance caused by baking is reduced compared to UV thermosetting adhesive. In addition, during the low curing reaction stage and / or the normal curing reaction stage, the relative positions between the lens components can be actively calibrated, thereby improving the degradation of optical performance caused by the curing process of the adhesive material;

[0006] Strong flexibility: Hot melt processing can be applied to a variety of materials, such as hot melt adhesive, hot melt powder, hot melt film, etc., which makes the assembly of optical lenses more flexible and different materials and processes can be selected as needed.

[0007] In the process of implementing the solution, the inventors found that the following problems existed in the prior art and have not been well solved: the hot melt tube of the hot melt device rises after the glue discharge is completed. During the rising period, the lens assembly that has been glued needs to be removed from the fixture and the lens assembly that needs to be glued needs to be reinstalled. At the moment when the hot melt tube head rises, glue threads are easily generated. Although the tube body has a certain amount of heat, the position where the threads are discharged will be far away from the tube body, and the heat cannot be transferred, causing it to become cold and hard. When the glue is applied next time, hard glue will be embedded in the lens assembly, which will not only cause defects and debris in the assembly, but also affect the adhesion and tightness after gluing. Utility Model Content

[0008] The main purpose of the utility model is to provide a hot melt device for assembling an optical lens, which can effectively solve the problems in the background technology.

[0009] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0010] A hot melt device for assembling an optical lens comprises a hot melt gun, a rubber hose is connected to the bottom end of the side wall of the hot melt gun, a hot melt tube is connected to the bottom of the hot melt gun, side seats are arranged at both ends below one side of the hot melt gun, a screw rod is rotatably connected to the top end between the side seats, a sliding rod is rotatably connected to the bottom end between the side seats, an internally threaded support tube is threadedly connected to the screw rod, a sliding tube bracket is slidably connected to the sliding rod, a bottom plate is fixed between the internally threaded support tube and the sliding tube bracket and at one end close to the hot melt gun, a bottom box is fixed on the top of the bottom plate, a cover plate is arranged on the top of the bottom box, a cotton pad is embedded in the interior of the bottom box, and a cotton cloth is covered on the outer wall of the cotton pad, a micro motor is fixed to the outside of one of the side seats, and a through cavity is drilled on the top of the cover plate.

[0011] Preferably, one end of the screw rod is in communication with one of the side seats, and one end of the screw rod passing through the side seat is fixedly connected to the output end of the micro motor.

[0012] Preferably, the four corners of the top of the bottom box are all provided with card slots, and the four corners of the bottom of the cover plate are all provided with card blocks, and the card blocks are respectively connected with the card slots at matching positions.

[0013] Preferably, the outer dimensions of the cotton pad match the inner dimensions of the bottom box.

[0014] Preferably, the width of the through cavity is greater than the diameter of the outside of the hot melt tube.

[0015] Preferably, a fixing frame is fixed to the outer wall of the top end of the hot melt gun.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. After the hot melt tube rises to the top of the cover plate, the micro motor drives the screw to rotate after working, and the threaded connection between the internal thread support tube and the screw and the sliding connection between the sliding tube bracket and the sliding rod drive the bottom plate to move to the bottom of the hot melt tube. At this time, the descent of the hot melt tube causes its bottom to drop and insert into the through cavity to contact the cotton cloth. The glue thread can adhere to the cotton cloth and be removed. Then the hot melt tube rises again, and the reverse work of the micro motor moves the bottom plate out from under the hot melt tube. This method can effectively remove the glue thread and residual glue, avoiding the problem of affecting the later hot melt gluing work.

[0018] 2. When the micro motor works and drives the through cavity to different positions under the hot melt tube, the hot melt tube can contact different positions on the top of the cotton cloth to complete the degumming effect, increase the service life of the cotton cloth, and avoid the problem of incomplete degumming caused by long-term use of one part.

[0019] 3. After the cover plate and the bottom box are snapped together and separated, the cotton pad and cotton cloth can be directly taken out from the bottom box and replaced, avoiding the problem of excessive glue sticking and affecting the use. The operation is simple, convenient and low-cost. BRIEF DESCRIPTION OF THE DRAWINGS
