Description

TECHNICAL FIELD

The automobile rearview mirror is an important safety part, and its mirror surface, shape and operation are quite particular.

[0003] In the production process of the lens, cutting and hot pressing are two steps in close proximity. In the existing production process, the lenses are collected after cutting to a certain amount and then transported to the hot pressing device. The lenses are prone to be knocked or scratched during transportation, which does not meet the efficient and safe production requirements of mechanical automation production. The main shaping step of the lens relies on the implementation of the precision mechanical hot pressing process. After the hot pressing process of the mold is completed, manual demolding is required. In this process, the mold is still in a high temperature state. If manual demolding is directly used, the lens and the mold are directly contacted with the external cold air, which may cause the lens and the mold to be bonded.

[0056] The sealing assembly 7 comprises a compression spring 71, a sealing cover plate 72 and a hot pressing column 73, one end of the compression spring 71 is fixedly connected at the top of the inner wall of the hot pressing box body 11 away from the limiting cylinder 41, the compression spring 71 is slidingly connected with the inside of the limiting sliding groove 93, the sealing cover plate 72 is fixedly connected at the other end of the compression spring 71, and the hot pressing column 73 is fixedly connected at the bottom of the sealing cover plate 72.

[0057] The convex plate assembly 8 comprises a sliding flat plate two 81 and a hot pressing convex plate 82, the sliding flat plate two 81 is fixedly connected at the bottom of the hot pressing column 73, and the hot pressing convex plate 82 is fixedly connected at the bottom of the sliding flat plate two 81; the hot pressing convex plate 82 is adapted in size to the hot pressing concave plate 51.

[0058] The inner wall of the hot pressing box body 11 away from the compression spring 71 is slidingly connected with an electric signal trigger block 14, and there is an electrical connection relationship among the electric signal trigger block 14, the hot pressing concave plate 51, the hot pressing convex plate 82 and the hot pressing box body 11; when the electric signal trigger block 14 is abutted by the sliding flat plate one 53, an electrical signal is sent to heat the hot pressing concave plate 51 and the hot pressing convex plate 82 and to keep the inside of the hot pressing box body 11 warm.

[0059] Working principle: in the initial state,

[0060] The rotating rod 24 is located at the edge of the limiting cylinder 41, the cutting spring 23 is not stretched, the limiting cylinder 41 is not affected by the rotation of the rotating rod 24, the limiting cylinder 41 does not drive the limiting rod 42 to displace, the sliding plate 53 cannot fall along the vertical sliding groove 91, the trigger block 14 affected by the electric signal is not triggered, and the trigger plate 61 located in the falling path of the sliding plate 53 is not triggered, so that the limiting plate 63 does not release the displacement restriction of the sealing cover plate 72, the sealing cover plate 72 does not move along the limiting sliding groove 93, the compression spring 71 is still in the compressed state, and the sliding plate 81 is in the prohibited state with the hot pressing convex plate 82 through the hot pressing column 73.

[0061] At this time, the moving bottom plate 31 does not receive the instruction of the electric signal trigger block 14 to open the moving bottom plate 31, and the moving bottom plate 31 does not open along the track opened at the bottom of the hot pressing box 11.

[0062] At this time, the weight cylinder at the bottom of the demolding spring 54 is not affected by external force, does not drive the demolding spring 54 to rise, and makes the demolding cover plate 52 in a stationary state.

[0063] In work,

[0064] The user places the uncut lens raw material at the cutting slot at the bottom of the cutting box 12, rotates the rotating handle 21 away from the limiting cylinder 41, and drives the rotating rod 24 to move in a circle through the rotating column 22. Because the cutting spring 23 is in a compressed state, the cutting spring 23 always pushes the cutting rod 25 to adhere to the inner wall of the cutting slot of the cutting box 12. Because it is limited by the shape of the cutting slot at the top of the cutting box 12, the cutting rod 25 displaces along the inner wall of the cutting slot, and the cutting rod 25 cuts the lens raw material through the diamond cutting head at the bottom thereof. When the rotating rod 24 moves in a circle to the position of the limiting cylinder 41, the diamond cutting head cuts the lens raw material into the same shape as the cutting slot. At this time, the cut lens is separated from the raw material bottom plate.

[0065] At this time, the rotating rod 24 drives the limiting cylinder 41 to displace, and because the size of the limiting cylinder 41 is greater than the size of the limiting slot on the surface of the cutting box 12, the limiting cylinder 41 will close the limiting slot after displacement. The limiting rod 42 is affected by the displacement of the limiting cylinder 41 and displaces in the same direction as the limiting cylinder 41. At this time, the state of confrontation between the limiting rod 42 and the sliding plate 53 is broken, and the sliding plate 53 begins to displace downward under the guidance of the sliding blocks arranged in the vertical sliding groove 91 on both sides of the sliding plate 53.

[0066] The electric signal trigger block 14 is located in the middle of the falling track of the sliding plate 53, and the trigger plate 61 is located at the bottom of the falling track of the sliding plate 53. The electric signal trigger block 14 is triggered first by the sliding plate 53, and then the electric signal trigger block 14 sends an electric signal to heat the concave plate 51 and the convex plate 82 to start preheating. The trigger plate 61 is triggered later by the sliding plate 53. The side of the trigger plate 61 close to the sliding plate 53 is pressed down, and the side of the trigger plate 61 away from the sliding plate 53 contacts the fixed bottom plate 33. The sliding plate 53 falls to the top surface of the moving chassis and stops falling. Because the size of the falling slot 32 in the bottom assembly 3 is larger than that of the four demolding springs 54 at the bottom of the sliding plate 53, the demolding springs 54 will pass through the falling slot 32 and be suspended, and the sliding plate 53 will block the falling slot 32.

[0067] Due to the influence of the side of the trigger plate 61 close to the sliding plate 53 being pressed down, the vertical plate on the other side of the trigger plate 61 will rise and lift one side of the limiting plate 63 at the top. Due to the influence of the rising force on one side and the limiting spring 64 in the middle of the limiting plate 63, the other side of the limiting plate 63 starts to fall, and the state of confrontation with the sealing cover plate 72 is released. At this time, the compression spring 71 close to one side of the limiting plate 63 pushes the sliding blocks on both sides of the sealing cover plate 72 to slide in the limiting sliding groove 93 under the elastic stretching action of the compression spring 71. The sealing cover plate 72 slides in the opposite direction of the limiting plate 63. When the sealing cover plate 72 slides to the end of the limiting sliding groove 93, the sealing cover plate 72 will block the cutting slot formed by the falling of the hot pressing concave plate 51. At this time, the inside of the hot pressing box body 11 is in a sealed state.

[0068] Because the sliding plate 81 slides in the horizontal sliding groove 92, and the sliding plate 81 is fixedly connected at the bottom of the hot pressing column 73, the sliding plate 81 and the hot pressing convex plate 82 slide in the moving direction of the sealing cover plate 72. When the sealing cover plate 72 reaches the bottom of the limiting sliding groove 93, the sliding blocks on both sides of the sliding plate 81 are connected with the vertical sliding groove 91. Under the influence of gravity, the sliding plate 81 and the hot pressing convex plate 82 slide downward. The hot pressing column 73 starts to apply pressure downward, so that the hot pressing convex plate 82 and the hot pressing concave plate 51 are hot pressed.

[0069] When the preset heat-pressing time of the electric signal trigger block 14 ends, the electric signal trigger block 14 sends a heat preservation instruction, and at this time, the heat-pressing box 11 is in a sealed state, and the heat preservation effect will not be affected by the external temperature. When the preset heat preservation time of the electric signal trigger block 14 ends, at this time, the temperature inside the heat-pressing box 11 is the same as the external temperature, and the formed lens gradually adapts to the change of the environmental temperature, thereby avoiding the lens from being suddenly cooled and shrunk, and the formed lens is not adhered to the mold. At this time, the user pulls the two groups of moving bottom plates 31, and the two groups of moving bottom plates 31 start to open to both sides along the tracks arranged on the heat-pressing box 11. At this time, the heat-pressing rod restricts the falling of the sliding plate two 81 and the heat-pressing convex plate 82, the sliding plate one 53 and the heat-pressing concave plate 51 fall under the influence of gravity and the vertical sliding groove 91, at this time, the heat-pressing convex plate 82 is disconnected from the formed lens, and the sliding plate one 53 and the heat-pressing concave plate 51 continue to fall until they fall to the next assembly plane. At this time, the counterweight cylinder at the bottom of the demolding spring 54 is in contact with the plane, the counterweight spring is compressed and lifts the demolding cover plate 52, and the demolding cover plate 52 drives the formed lens to separate from the heat-pressing concave plate 51. At this time, the demolding is completed.
