Description

Technical Field

[0001] The utility model relates to the technical field of glasses splicing machines, in particular to a machine for splicing plastic glasses. Background Art

[0002] The plastic glasses head splicing machine is a special equipment used to splice the heads of plastic plate glasses with frames or lenses. It achieves fast and firm splicing through vibration and friction, and has the advantages of automatic feeding, accurate positioning, fast processing speed, high yield rate, etc. It can effectively improve production efficiency and reduce labor intensity.

[0003] Ultrasonic welding is an effective method to improve the firmness of the connection between the eyeglass head and the frame. In the specific operation, the lens is first placed in the placement groove of the processing and assembly device, and then the head is placed on the frame, and it is ensured that the first positioning groove of the head is tightly abutted against the first positioning block, and the positioning plate is fitted with both sides of the inner wall of the hinge groove, so as to accurately limit and fix the head, and finally, the head is firmly welded to the frame using an ultrasonic welding machine, so as to achieve a stable connection between the head and the frame;

[0032] As a further implementation of the present invention, the top of the chassis 21 is fixedly connected to a frame 22, the inner side of the frame 22 near the upper end is fixedly connected to a first electric telescopic rod 23, the rear end of the first electric telescopic rod 23 is fixedly connected to a linear motor 24, the bottom end of the linear motor 24 is fixedly connected to a second electric telescopic rod 25, and the lower end of the second electric telescopic rod 25 is fixedly connected to an ultrasonic welding device 26. Through the above arrangement, the existing displacement drive technology is used to control the position of the ultrasonic welding device 26, so as to achieve real-time adjustment of the welding position between the eyeglass frame 5 and the eyeglass pile head 6;

[0033] The rear end of the controller 1 is fixedly connected to the front end of the chassis 21, the controller 1, the first electric telescopic rod 23, the second electric telescopic rod 25 and the ultrasonic welding device 26 are electrically connected, the second servo motor 28, the first servo motor 27 and the controller 1 are electrically connected, the chassis 21 is provided with a mounting groove on the inner side close to the first servo motor 27 and the second servo motor 28, the first servo motor 27 is embedded and installed inside the mounting groove of the chassis 21, the second servo motor 28 protrudes from the mounting groove of the chassis 21, the gear 29 and the toothed disc 32 are in the same horizontal plane, and a gap is set between the bottom end of the mold disc 31 and the top end of the gear 29. Through the above settings, the driving device can be controlled by the controller 1, thereby realizing the position adjustment and welding of the glasses frame 5 and the glasses pile head 6;

[0034] As a further implementation of this solution, the upper end of the glasses frame 5 and the glasses stump 6 are welded and fixed, the mold groove 37 passes through the upper end of the mold plate 31, the glasses frame 5 is embedded and installed in the mold groove 37, the inner side of the toothed plate 32 is penetrated with a threaded hole, the inner side of the mold plate 31 is provided with a threaded hole, the mold plate 31 is fixedly connected to the toothed plate 32 by a bolt 33, the outer side of the limiting shaft 36 is fixedly connected with a bearing, and the limiting shaft 36 is rotatably connected to the inner side of the station plate 41 through the bearing.

At the same time, the toothed plate 32 and the mold plate 31 are provided with a detachable structure, and the mold plate 31 can be replaced according to different batches of glasses frames 5, thereby improving the flexibility of the device.

[0035] As a further implementation scheme of the present scheme, the outer through groove 42 passes through the horizontal outer side of the work station disk 41, and the opening shape of the outer through groove 42 is cylindrical. The outer through groove 42 passes through the upper end of the work station disk 41, and the toothed disk 32 is embedded and installed inside the outer through groove 42. The first permanent magnet block 35 and the second permanent magnet block 43 are magnetically attracted to each other, and a gap is set between the bottom end of the mold disk 31 and the top end of the work station disk 41. Through the above-mentioned arrangement, the toothed disk 32 and the mold disk 31 are limited when they rotate. At the same time, through the magnetic attraction of the second permanent magnet block 43 and the first permanent magnet block 35, the mold disk 31 and the toothed disk 32 are prevented from rotating when the eyeglass frame 5 and the eyeglass pile head 6 are displaced, thereby ensuring the accuracy of the position adjustment of the eyeglass frame 5.

[0036] Working process: when ultrasonically welding the eyeglass frame 5 and the eyeglass pile head 6, the eyeglass frame 5 is embedded and installed in the inside of the mold groove 37, and then a little colloid is applied to the bottom end of the eyeglass pile head 6 near the center, and then the eyeglass pile head 6 is glued to the upper end of the eyeglass frame 5 to achieve a temporary limiting effect. After the installation is completed, the position of the toothed disc 32 is adjusted so that the first permanent magnet block 35 fixed on the inner side of the toothed disc 32 and the second permanent magnet block 43 fixed on the work station disk 41 generate magnetic attraction, which can prevent the toothed disc 32 from rotating when the work station disk 41 rotates. At this time, the first servo motor 27 is started to drive the external shaft 44 and the work station disk 41 to rotate. When the toothed disc 32 corresponding to the eyeglass frame 5 and the eyeglass pile head 6 is installed and meshes with the gear 29, the first servo motor 27 is stopped. At this time, the linear motor 24 is driven to move backward by the first electric telescopic rod 23. The linear motor 24 adjusts the left and right positions of the second electric telescopic rod 25, and the ultrasonic welding equipment 26 is controlled to move downward by the second electric telescopic rod 25. The ultrasonic welding equipment 26 performs ultrasonic welding between the eyeglass frame 5 and the eyeglass head 6. After the welding of the eyeglass head 6 near the front end of the eyeglass frame 5 is completed, the eyeglass head 6 near the rear end of the eyeglass frame 5 is welded. When the welding surface needs to be adjusted, the gear 29 is driven to rotate by the second servo motor 28, and the gear 29 drives the outer meshing toothed disc 32 to rotate. The toothed disc 32 drives the limiting shaft 36 and the mold disc 31 to rotate. The limiting shaft 36 is rotatably connected to the work station disc 41 through the bearing, which plays a role in limiting the rotation of the toothed disc 32 and the mold disc 31. The rotation of the mold disc 31 drives the eyeglass head 6 and the eyeglass frame 5 to rotate as a whole through the mold groove 37, and then the other surfaces of the eyeglass frame 5 and the eyeglass head 6 are welded. In summary, the device can adjust the position of the eyeglass frame 5 and the eyeglass head 6. This adjustment method does not require the eyeglass frame 5 and the eyeglass head 6 to be moved. In this way, problems such as misalignment or offset of the welding points when the eyeglass frame 5 and the eyeglass head 6 are welded can be solved, thereby improving the quality of the final welding.
