[0029] At present, the method commonly used for positioning the front and rear angles of glass is to set a photoelectric switch near the glass running route, when the front side of the glass moves to the position of the photoelectric switch, the photoelectric switch will send an induction signal, so as to position the front angle position of the glass, and the glass continues to move forward until the whole leaves the photoelectric switch, at this time, the photoelectric switch will give a leaving signal, so as to position the rear angle position of the glass, however, the glass needs to be water cooled in the processing process, which leads to the water accumulation on the surface of the glass, thereby affecting the detection accuracy of the photoelectric switch.
[0030] In order to solve the above problems, the present application provides a position detection mechanism, which aims to solve the problem of low detection accuracy of the existing detection mechanism using a separate photoelectric switch.
[0031] As Figure 1 and Figure 2 In an embodiment, the position detection mechanism 100 comprises a mounting seat 10, a detection piece 20 and a detection rod 30, the detection piece 20 is installed on the mounting seat 10, the detection rod 30 is rotationally connected to the mounting seat 10, two ends of the detection rod 30 are respectively a detection end 31 and a contact end 32, the contact end 32 of the detection rod 30 is used for abutting with the external glass 80, and the detection rod 30 has a first state and a second state.
[0032] In the embodiment, the position detection mechanism 100 is installed near the running direction of the external glass 80, one end of the detection rod 30 is used as the contact end 32 and extends out of the mounting seat 10 to contact the external glass 80, and the other end is used as the detection end 31 and located above the detection piece 20, when the external glass 80 abuts with the contact end 32 of the detection rod 30, the detection rod 30 is driven to rotate relative to the mounting seat 10, and then the detection end 31 of the detection rod 30 changes the position relative to the detection piece 20. When the detection end 31 is opposite to the detection position of the detection piece 20, the detection rod 30 is in the first state, and when the detection end 31 deviates from the detection position of the detection piece 20, the detection rod 30 is in the second state.
[0033] The position detection mechanism 100 detects that the detection rod 30 is in the first state in the initial state, when the outer glass 80 moves until the front angle abuts against the contact end 32 of the detection rod 30, at this time, the glass 80 drives the detection rod 30 to rotate relative to the mounting base 10, and then drives the detection end 31 of the detection rod 30 to deviate relative to the first detection position, so that the detection rod 30 changes from the first state to the second state, at this time, the detection piece 20 senses the position change of the detection rod 30 through the inductive element, and sends a position signal to the external control system, so as to position the front angle of the outer glass 80; when the outer glass 80 continues to move until the whole is separated from the position detection mechanism 100, at this time, the detection rod 30 is reset, and changes from the second state to the first state, at this time, the detection piece 20 sends another position signal to position the back angle of the outer glass 80, so as to realize accurate positioning of the front and back angles of the outer glass 80.
[0034] The position detection mechanism 100 judges the positions of the front and back angles of the glass 80 by detecting the position relationship between the detection end 31 of the detection rod 30 and the detection piece 20, reduces the influence of the environment on the detection result, and improves the positioning accuracy.
[0035] As Figure 1 and Figure 2 In an embodiment, the position detection mechanism 100 further comprises a rotating piece 40, the rotating piece 40 comprises a fixed column 41 and a bearing 42, the fixed column 41 is inserted and mounted in the mounting base 10 and partially extends out of the mounting base 10, the bearing 42 is sleeved on the outer circumferential side of the fixed column 41, and the detection rod 30 is provided with a mounting hole, and the detection rod 30 is sleeved on the outer circumferential side of the bearing 42 through the mounting hole.
[0036] In the embodiment, the rotating piece 40 comprises a fixed column 41 and a bearing 42, the fixed column 41 is partially fixedly installed in the mounting base 10 and serves as a rotating fulcrum of the detection rod 30, and the other part extends out of the mounting base 10, the inner ring of the bearing 42 is sleeved on the extended part of the fixed column 41, and the detection rod 30 is sleeved on the outer ring of the bearing 42 through the mounting hole. The setting of the rotating piece 40 improves the rotating fluency of the detection rod 30, so that the detection piece 20 can more accurately detect the position change of the detection rod 30, and the detection accuracy of the position detection mechanism 100 is improved.
[0037] As Figure 1 and Figure 2 In an embodiment, the position detection mechanism 100 further comprises a reset piece 50, one end of the reset piece 50 is mounted on the mounting base 10, and the other end is connected with the detection rod 30.
[0038] In the embodiment, the reset member 50 can restore the detection rod 30 to the initial predetermined position, i.e. the first state, after the position detection mechanism 100 completes a position detection operation. Specifically, one end of the reset member 50 is fixedly installed on the mounting base 10, and the other end is connected with the detection rod 30. When the detection rod 30 deviates from the initial position due to the action of the external glass 80 during the detection process, the reset member 50 stores energy. Once the action force applied by the external glass 80 disappears, the reset member 50 releases the stored energy to pull the detection rod 30 back to the initial position. The arrangement of the reset member 50 ensures that the detection rod 30 is in the same position before each detection, so that the detection result has high consistency, and the detection accuracy is improved.
[0039] In an embodiment, the reset member 50 is a spring. Figure 1 Figure 2 In an embodiment, the reset member 50 is a spring.
[0040] In the embodiment, the spring has simple structure, low cost, and is easy to maintain. The use of the spring as the reset member 50 can effectively reduce the production cost of the reset member 50. Meanwhile, the reset action of the spring is fast and reliable, which can meet the demand of high-frequency detection of the position detection mechanism 100, and improve the detection practicability of the position detection mechanism 100.
[0041] In other embodiments, the reset member 50 can also be a spring cord.
[0042] In an embodiment, the position detection mechanism 100 further comprises a limiting member 60 installed on the mounting base 10. When the detection rod 30 is in the first state, one side of the detection rod 30 abuts against the limiting member 60. Figure 1 Figure 2 In an embodiment, the position detection mechanism 100 further comprises a limiting member 60 installed on the mounting base 10. When the detection rod 30 is in the first state, one side of the detection rod 30 abuts against the limiting member 60.
[0043] In the embodiment, the limiting member 60 is usually made of hard material, such as metal, plastic or other wear-resistant material, to ensure that it can reliably limit the movement of the detection rod 30. The limiting member 60 can be a protrusion, a stop block or a special limiting pin fixed on the mounting base 10. When the detection rod 30 is reset, the arrangement of the limiting member 60 can prevent excessive displacement of the detection rod 30, and ensure that the detection rod 30 does not exceed the designed position range during the reset process, thereby improving the service life of the position detection mechanism 100.
[0044] In an embodiment, the detection member 20 is an optical sensor. Figure 1 Figure 2 In an embodiment, the detection member 20 is an optical sensor.
[0045] In the embodiment, the detecting member 20 is a photoelectric sensor, which can emit laser light. When the detection rod 30 is in the first state, the emitted laser light can be blocked by the detecting end 31. When the detection rod 30 is in the second state, the emitted laser light can directly reach the external space. The detecting member 20 can emit corresponding signals to the external control system through the change of the laser light path, so as to realize the front and rear angle positioning of the external glass 80.
[0046] As Figure 1 and Figure 2 , the detection rod 30 is arranged in a telescopic manner.
[0047] In the embodiment, the detection rod 30 includes a fixed part and a telescopic part. The telescopic part is inserted into the fixed part. A driving member is installed in the telescopic part. The two ends of the driving member are connected with the fixed part and the telescopic part respectively, so as to drive the telescopic part to extend or retract along the length direction of the fixed part, so as to adapt to external glasses of different sizes, and ensure that the glasses 80 of different sizes can be detected, thereby improving the versatility of the position detection mechanism.
[0048] As Figure 1 and Figure 2 In an embodiment, the position detection mechanism 100 further includes a grinding wheel 70. The grinding wheel 70 is rotationally connected to the contact end 32 of the detection rod 30. The grinding wheel 70 is used to abut against the external glass 80 and chamfer the external glass 80.
[0049] In the embodiment, the position detection mechanism 100 further includes the grinding wheel 70. After the detecting member 20 detects the front angle position of the external glass 80, the external control system controls the external glass 80 to stop moving, and simultaneously starts the grinding wheel 70 installed on the contact end 32 to rotate, so as to chamfer the external glass 80. Similarly, the grinding wheel 70 can also chamfer the rear angle of the external glass 80. The grinding wheel 70 is arranged, so that the position detection mechanism 100 can not only position the front and rear angles of the glass 80, but also process the glass 80, thereby reducing the subsequent processing steps of the glass 80, and improving the practicability of the position detection mechanism 100. The material of the grinding wheel can be diamond. The diamond has high hardness. The diamond grinding wheel 70 can grind the glass 80 at a higher speed and pressure, thereby improving the processing efficiency. Meanwhile, the diamond has good wear resistance and long service life, thereby reducing the replacement frequency of the grinding wheel 70 and improving the service life.
[0050] As Figure 1 and Figure 2 In an embodiment, the number of the position detection mechanisms 100 is two. The two position detection mechanisms 100 are arranged in a spaced manner along the width direction of the external glass 80.
[0051] In the embodiment, two position detection mechanisms 100 are arranged at intervals along the width direction of the outer glass 80, so that two front corners / rear corners of the glass 80 can be chamfered at the same time, thereby improving the work efficiency.
