Description

Technical Field

[0001] The invention relates to the field of glasses processing, in particular to a multi-station copper core punching device for glasses legs. Background Art

[0002] The finished glasses frame is mainly divided into two parts: the frame and the temples. The copper core is to drive the metal copper core into the plastic temples. Its function is equivalent to forming the internal support skeleton of the temples. It is the main process of forming the plastic plate temples. After the copper core is driven into the temples, it is like injecting a backbone into the temples, giving them strength.

[0003] After the glasses frame is assembled, it needs to be adjusted, that is, the glasses frame and the glasses legs can be adjusted to different bending arc shapes of the glasses legs, as well as the inclination angle of the glasses legs, the spacing of the glasses legs, etc. according to the different characteristics of people in different regions, the height of the bridge of the nose, the size of the head, etc., which greatly improves people's wearing comfort and experience. In the prior art, the equipment has a leg handle preheating device and a copper core insertion device, but the loading and unloading between the devices are mainly completed manually. If a manipulator or an automatic conveying device is used, it is mainly aimed at transferring the mold of the glasses legs with the already formed glasses legs on the copper core insertion device, and the empty mold of the leg handle preheating device is conveyed to the part to be heated through the track. The remaining steps of placing the copper core in the preheating part of the copper core insertion device, removing the formed glasses legs from the mold, and transferring the mold with the preheated leg handle to the copper core insertion device must be completed manually. In order to achieve automation, basically no need for manual operation, and further improve the processing efficiency, a multi-station glasses leg copper core punching equipment is needed.

The plurality of transmission members 16 can rotate in planes in different directions to change the position and direction of the mounting seat 13.

[0034] like Figure 11-13 As shown, the material storage device 2 is a material rack for placing copper cores, and the material storage device 2 includes a frame body 21 and a limiting plate 22. The frame body 21 is placed on the frame, and the limiting plate 22 is detachably connected to the frame body 21.

The mold 32 is provided with a slot 321 for placing the glasses leg, the slot 321 opens upward, and is further provided with a first power source 33 and an upper push element 34 connected to the first power source 33.

[0037] like Figure 3-6 As shown, the copper core clamp 11 includes a left clamp arm 111 and a right clamp arm 112 that are relatively arranged, at least one of the left clamp arm 111 and the right clamp arm 112 is connected to a second power source 113, and the second power source 113 drives the left and right clamp arms 112 to perform a clamping action. The left clamp arm 111 has a first limiting portion 1111 that cooperates with the left side of the copper core, and the right clamp arm 112 has a second limiting portion 1121 that cooperates with the right side of the copper core. The first limiting portion 1111 and the second limiting portion 1121 are symmetrical to each other. The front end of the left clamp arm 111 is folded inward to form a first stopper 1112, and the front end of the right clamp arm 112 is folded inward to form a second stopper 1122.

[0038] The first limiting portion 1111 and the second limiting portion 1121 are respectively provided with a first contact surface and a second contact surface, and the first contact surface and the second contact surface are respectively used for directly or indirectly contacting with the left and right side surfaces of the copper core.

[0039] The mold clamp 14 has a protrusion that matches the mold slot and is used to prevent the mold from falling off when the left and right clamp arms are clamped together.

[0040] The leg handle preheating device 5 is arranged adjacent to the storage device 2, and a copper core inserting device 4 is arranged on one side of the leg handle preheating device 5 and one side of the storage device 2. The copper core inserting devices 4 on both sides can be used alternately.

[0041] like Fig.10 As shown, the temple processing mainly includes preheating the copper core 61 and the temple handle 62 respectively, inserting the copper core 61 into the temple blank to obtain the molded temple 6. In the first step, the heating mold with the temple handle 62 is sent into the heating mechanism through the feeder provided by the temple handle preheating device for high-frequency heating, and is automatically sent out through the guide rail of the temple handle preheating device after a period of time; a waiting mechanism is provided under the heating mechanism of the temple handle preheating device, and an empty mold is provided on the waiting mechanism, which is a mold that can be opened and closed, and the temple handle 62 in the heated heating mold is punched down and placed in the mold cavity;

[0042] The copper core clamp of the conveying mechanism 1 clamps the copper core 61 of the storage device 2, wherein the conveying mechanism 1 is a program-controlled robot, and can take the copper core 61 of the storage device 2 from a preset point, and the conveying mechanism 1 conveys the copper core 61 to one of the copper core insertion devices 4 to punch the copper core. During this period, the direction of the mounting seat 13 turns horizontally, and the copper core clamp ensures that the orientation of the copper core 61 is consistent with the rotation direction of the mounting seat 13. The copper core is inserted horizontally into the copper core insertion device 4 for preheating. While preheating, the conveying mechanism 1 moves to the leg handle preheating device 5 to clamp the mold with the preheated leg handle 62 and place it in the processing position of the same copper core insertion device 4. The device will insert the preheated copper core into the preheated leg handle 62, and a certain period of holding time is required after insertion. The copper core 61 and the leg handle 62 of the glasses are cured and shaped; while the curing and shaped are being carried out, the conveying mechanism 1 clamps the mold on the other side and places it on the demolding device 3, and the finished product is pushed out of the outlet. The conveying mechanism 1 transfers the finished product to the material tray, and the robot places the empty mold after demolding on the waiting mechanism of the leg handle preheating device 5. While waiting for the leg handle in the heating device to be heated, the step of taking out the copper core is repeated again, and the taken out copper core 62 is placed in a copper core insertion device 4 that has just been demolded. This cycle is repeated, and the heating time of the leg handle preheating device 5 and the insertion and curing time of the two copper core insertion devices 4 are fully utilized. The two copper core insertion devices 4 are cross-utilized to improve the processing efficiency. The leg handle preheating device 5 can work without interruption, which greatly improves the utilization rate of the equipment.

[0043] The heating time of the leg handle preheating device 5 is about 5 seconds, and the curing time of the copper core insertion device 4 is more than ten seconds, so the purpose of cross-use can be achieved.
