Description

Technical Field

[0001] This utility model relates to the field of glass production equipment technology, specifically to a chamfering trigger mechanism and a chamfering system including the chamfering trigger mechanism. Background Technology

[0002] In chamfering systems, a belt typically moves the glass to a designated position and initiates chamfering upon receiving a chamfering signal. Because the glass requires cooling water during grinding, the signal triggering mechanism in existing technologies exhibits unstable signal output in the presence of water. Furthermore, the glass dust generated during grinding causes existing signal triggering mechanisms to become less flexible after a period of use, and contact corrosion occurs, reducing their lifespan. Utility Model Content

[0003] In view of this, in order to solve the problems of the prior art, the present invention provides a chamfering trigger mechanism to solve the problems of unstable output signal and short service life of the trigger mechanism in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A chamfering trigger mechanism includes a mounting plate and a sensing component, a swing arm assembly, an elastic component, and a limiting component disposed on the mounting plate. The sensing component includes a proximity switch. The swing arm assembly includes a bearing seat fixed to the mounting plate and a swing arm rotatably connected to the bearing seat. A rotating wheel is disposed at the bottom end of the swing arm, and the bottom surface of the rotating wheel is located below the bottom edge of the mounting plate. The top end of the swing arm is located on one side of the sensing component. The limiting component is located on one side of the top end of the swing arm. One end of the elastic component is connected to the swing arm.

[0006] The swing arm assembly has a first state and a second state. When the swing arm assembly is in the first state, one end of the limiting component contacts one side of the top of the swing arm, and the top of the swing arm does not coincide with the orthographic projection of the sensing end of the proximity switch on the mounting plate. When the swing arm assembly is in the second state, there is a gap between one end of the limiting component and one side of the top of the swing arm, and the top of the swing arm at least partially coincides with the orthographic projection of the sensing end of the proximity switch on the mounting plate. The proximity switch has good waterproof performance, and since it has no mechanical movement and does not generate wear, it can reduce downtime; its output signal is more stable, avoiding malfunctions caused by chamfering.

[0007] According to a preferred embodiment of the present invention, the swing arm includes a first part, a second part, an extension part, and a protrusion part. The two ends of the first part are fixedly connected to the protrusion part and the second part, respectively. The end of the second part away from the first part is fixedly connected to one end of the extension part. The first part is perpendicular to the second part, and the extension part is perpendicular to the second part. The protrusion part is close to the top edge of the mounting plate, and the extension part is close to the bottom edge of the mounting plate.

[0008] According to a preferred embodiment of the present invention, the length direction of the protrusion is parallel to the length direction of the first part, the end of the first part away from the protrusion is rotatably connected to the bearing seat, and the rotating wheel is rotatably connected to the extension. The cooperation between the swing arm and the bearing seat can improve the flexibility of the swing arm's swing and reduce wear. The rotating wheel on the extension of the swing arm can rotate with the forward movement of the glass, preventing sliding friction and avoiding scratches to the glass.

[0009] According to a preferred embodiment of the present invention, the sensing component further includes a first fixed base, one side of which is fixedly connected to one side of the mounting plate, the proximity switch is fixedly connected to the other side of the first fixed base, and the sensing end of the proximity switch is located between the two sides of the first fixed base.

[0010] According to a preferred embodiment of the present invention, the protrusion is located between the two sides of the first fixed base, and the distance from the protrusion to the mounting plate is less than the distance from the sensing end of the proximity switch to the mounting plate.

[0011] According to a preferred embodiment of the present invention, when the swing arm assembly is in the second state, the horizontal distance between the protrusion and the sensing end of the proximity switch is less than or equal to 3mm, ensuring that a part of the swing arm can swing into the effective sensing distance of the sensing end of the proximity switch, thereby triggering the proximity switch to generate a signal.

[0012] According to a preferred embodiment of the present invention, the elastic component includes an elastic element, a second fixing seat, and a first bolt and nut assembly. One side of the second fixing seat is fixedly connected to one side of the mounting plate, and the first bolt and nut assembly is connected to the other side of the second fixing seat. One end of the elastic element is connected to one end of the bolt of the first bolt and nut assembly. In some embodiments of the present invention, one end of the bolt of the first bolt and nut assembly has a circular hole, and one end of the elastic element can hook into the circular hole. In addition, one side of the second fixing seat has a threaded hole, which can be threadedly connected to the bolt of the first bolt and nut assembly, thereby adjusting the length of the bolt extension to adjust the stretching length of the elastic element.

[0013] According to a preferred embodiment of the present invention, the first part has a plurality of through holes extending through its thickness direction on the side near the elastic component. The plurality of through holes are arranged at intervals along the length direction of the first part, and the other end of the elastic component is connected to one of the through holes. When the swing arm assembly is in the second state, the elastic component is in a stretched state. The plurality of through holes on the first part are provided to facilitate adjustment of the angle of the elastic component, thereby adjusting the extension and contraction range of the elastic component.

[0014] According to a preferred embodiment of the present invention, the limiting component includes a third fixing seat and a second bolt and nut assembly. One side of the third fixing seat is fixedly connected to one side of the mounting plate, and the second bolt and nut assembly is connected to the other side of the third fixing seat. One end of the bolt of the second bolt and nut assembly faces the side of the second part near the limiting component. In some embodiments of the present invention, a threaded hole is also provided on one side of the third fixing seat, which can be threadedly connected to the bolt of the second bolt and nut assembly. This allows adjustment of the extension length of the bolt of the second bolt and nut assembly, thereby adjusting the distance between the end of the bolt and the side of the second part near the limiting component, ultimately facilitating the adjustment of the return position or angle of the swing arm.

[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0024] Reference Figures 1 to 3 This embodiment provides a chamfering system for chamfering glass. It includes an edge grinding machine, a chamfering trigger mechanism, and a control module. The chamfering trigger mechanism sends a chamfering trigger signal to the control module, which, upon receiving the signal, controls the edge grinding machine to chamfer the glass. The chamfering trigger mechanism includes a mounting plate 1, a rotating wheel 6, and a sensing component 2, a swing arm component 3, an elastic component 4, and a limiting component 5 mounted on the mounting plate 1. The sensing component 2 and the limiting component 5 are located at the top of the mounting plate 1, the rotating wheel 6 is located at the bottom of the mounting plate 1, and the elastic component 4 is located below the limiting component 5.

[0025] Further, the sensing component 2 includes a proximity switch 21 and a first fixing base. In this embodiment, the first fixing base includes a first plate 22, a second plate 23, and a third plate 24 connected in sequence. The first plate 22 is parallel to the third plate 24 and perpendicular to the second plate 23. The second plate 23 is located on the top surface of the first plate 22 and the third plate 24. One side of the first plate 22 is fixedly connected to one side of the mounting plate 1. The two ends of the second plate 23 are fixedly connected to one end of the first plate 22 and one end of the third plate 24, respectively. The proximity switch 21 is fixedly connected to the third plate 24, and the sensing end of the proximity switch 21 is located between the first plate 22 and the third plate 24. In this embodiment, the third plate 24 has an oblong hole 241 extending through its thickness direction. The proximity switch 21 is fixedly connected to the third plate 24 through the oblong hole 241 and two nuts (not shown). The oblong hole 241 facilitates the adjustment of the position of the proximity switch 21 on the third plate 24.

[0026] Furthermore, the swing arm assembly 3 includes a bearing seat 31 fixed on the mounting plate 1 and a swing arm rotatably connected to the bearing seat 31, with the top end of the swing arm located on one side of the sensing assembly 2; the cooperation between the swing arm and the bearing seat 31 can improve the flexibility of the swing arm swing and reduce wear.

[0027] Specifically, the swing arm includes a first part 32, a second part 33, an extension part 34, and a protrusion part 35. The two ends of the first part 32 are fixedly connected to the protrusion part 35 and the second part 33, respectively. The end of the second part 33 away from the first part 32 is fixedly connected to one end of the extension part 34. The first part 32 is perpendicular to the second part 33, and the extension part 34 is perpendicular to the second part 33. The first part 32 has a plurality of through holes 321 extending through its thickness direction on the side near the elastic component 4. The plurality of through holes 321 are arranged at intervals along the length direction of the first part 32. The protrusion part 35 is near the top edge of the mounting plate 1, and the extension part 34 is near the bottom edge of the mounting plate 1. The end of the first part 32 away from the protrusion part 35 is rotatably connected to the bearing seat 31. The length direction of the protrusion 35 is parallel to the length direction of the first part 32. The protrusion 35 is located between the first plate 22 and the third plate 24, and the distance from the protrusion 35 to the mounting plate 1 is less than the distance from the sensing end of the proximity switch 21 to the mounting plate 1. That is, the protrusion 35 is located between the sensing end of the proximity switch 21 and the first plate 22.

[0028] The rotating wheel 6 is located at the bottom end of the extension 34 of the swing arm. The bottom surface of the rotating wheel 6 is below the bottom edge of the mounting plate 1. As the glass moves along the length of the mounting plate 1 to continuously approach the rotating wheel 6 (before chamfering), the upper surface of the glass is 3-5 mm higher than the bottom surface of the rotating wheel 6. This ensures that as the glass continues to move forward, it can contact the bottom surface of the rotating wheel 6 and push the rotating wheel 6 upward to trigger the proximity switch 21. In this embodiment, the rotating wheel 6 is preferably a nylon wheel.

[0029] Furthermore, the elastic component 4 is located on one side of the first part 32 of the swing arm. The elastic component 4 includes an elastic element 41, a second fixing seat 42, and a first bolt and nut assembly 43. One side of the second fixing seat 42 is fixedly connected to one side of the mounting plate 1, and the other side of the second fixing seat 42 has a screw hole. The bolt of the first bolt and nut assembly 43 is threadedly connected to the other side of the second fixing seat 42 through the screw hole, and the position of the bolt is fixed by tightening the nut. In addition, a round hole is opened at the end of the bolt of the first bolt and nut assembly 43 near the first part 32. One end of the elastic element 41 is connected to the round hole, and the other end of the elastic element 41 is connected to one of the through holes 321 on the first part 32. By adjusting the length of the bolt extending from the first bolt and nut assembly 43, the extension length of the entire elastic element 41 can be adjusted. In this embodiment, the elastic element 41 is preferably a spring.

[0030] Furthermore, the limiting component 5 is located on one side of the top end of the first part 32 of the swing arm. The limiting component 5 includes a third fixing seat 51 and a second bolt and nut assembly 52. ​​One side of the third fixing seat 51 is fixedly connected to one side of the mounting plate 1, and the other side of the third fixing seat 51 is also provided with a screw hole. The bolt in the second bolt and nut assembly 52 is threadedly connected to the other side of the third fixing seat 51 through the screw hole, and the position of the bolt can be fixed by tightening the nut. The end of the bolt of the second bolt and nut assembly 52 near the swing arm is set towards the side of the second part 33 near the limiting component 5. In this embodiment, through the threaded connection between the bolt of the second bolt and nut assembly 52 and the third fixing seat 51, the length of the bolt extension of the second bolt and nut assembly 52 can be adjusted, thereby adjusting the distance between the end of the bolt and the side of the second part 33 near the limiting component 5, ultimately facilitating the adjustment of the return position or angle of the swing arm.

[0031] In this embodiment, the swing arm assembly 3 has a first state and a second state. During the transition from the first state to the second state, the swing arm rotates a certain angle away from the limiting assembly 5. Specifically, when the swing arm assembly 3 is in the first state, one end of the bolt of the second bolt and nut assembly 52 contacts the side of the top of the second part 33 near the limiting assembly 5, and the projection of the protrusion 35 onto the mounting plate 1 does not coincide with the projection of the sensing end of the proximity switch 21. When the swing arm assembly 3 is in the second state, there is a gap between one end of the bolt of the second bolt and nut assembly 52 and the side of the top of the second part 33 near the limiting assembly 5, the projection of the protrusion 35 onto the mounting plate 1 coincides with the projection of the sensing end of the proximity switch 21, and the horizontal distance between the protrusion 35 and the sensing end of the proximity switch 21 is less than or equal to 3mm, ensuring that a part of the swing arm can swing into the effective sensing distance of the sensing end of the proximity switch 21, thereby triggering the proximity switch 21 to generate a signal. Meanwhile, when the swing arm assembly 3 is in the second state, the elastic element 41 is still in the stretched state, ensuring that when the glass leaves the rotating wheel 6, the swing arm can return to its original position under the action of the elastic element 41's rebound force.

[0032] The working process of the chamfering trigger mechanism in this embodiment is as follows:

[0033] Mounting plate 1 is mounted on the edge grinding machine on the side away from the swing arm assembly 3. The glass moves horizontally along the length of mounting plate 1 below it, with the upper surface of the glass 5mm higher than the bottom surface of the rotating wheel 6. When the glass continues to move forward until it contacts the rotating wheel 6, it pushes the rotating wheel 6 upward, thereby causing the swing arm to rotate upward around the bearing seat 31. This causes the protrusion 35 to rotate until the horizontal distance between it and the sensing end of the proximity switch 21 is less than 3mm. At this time, the sensing end of the proximity switch 21 will sense the movement of the swing arm and output a trigger signal to the control module. After receiving this signal, the control module will control the edge grinding machine to start operating to chamfer the head of the glass. When the glass continues to move forward until it leaves the rotating wheel 6, the elastic element 41 will pull the swing arm back to the first state, and the protrusion 35 of the swing arm will leave the sensing end of the proximity switch 21. The proximity switch 21 will not output a signal, and the control module will control the edge grinding machine to operate again to chamfer the tail of the glass. At this point, the chamfering of a piece of glass is completed.

[0034] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
