[0001] The utility model relates to the technical field of glass detection of glass edge grinders, in particular to a high-precision anti-interference detection mechanism. Background Art
[0002] During the process of grinding the edges of glass by a glass edge grinder, the glass is generally conveyed to the workbench one by one. The grinding wheels installed on both sides of the workbench keep rotating to grind the conveyed glass, so as to continuously complete the edge grinding operation of multiple pieces of glass.
[0003] During continuous processing, the glass is fed into the equipment through a conveyor belt and sent out of the equipment. In this process, it is necessary to detect and calculate the number of glasses. The common detection method in the prior art is to set a non-contact sensor (such as a photoelectric sensor, etc.). The sensor emits a light source, and the presence or absence of the glass is detected according to the occlusion of the light beam by the glass. Such a design method has the following defects and deficiencies: affected by factors such as the processing environment and glass raw materials, the processed glass may be contaminated with impurities such as water stains. The existence of these water stains will affect the beam detection of the photoelectric sensor, reduce the detection accuracy of the sensor or even cause the sensor to misdetect, and then lead to misoperation of the equipment, affecting the processing accuracy of the equipment.
[0004] Therefore, there is an urgent need in the prior art to invent a glass detection mechanism that can avoid interference from impurities such as water stains on the glass. Summary of the Utility Model
[0005] In order to overcome at least one of the above-mentioned defects in the prior art, the utility model provides a high-precision anti-interference detection mechanism, which has the characteristics of strong anti-interference ability and high detection accuracy.
[0006] The technical solution adopted by the utility model to solve its problems is as follows:
[0007] A high-precision anti-interference detection mechanism is provided, which includes:
[0008] A bracket, on which a sensor and a rotatable rotating shaft are provided;
[0009] A swing arm, with a touch member and a gravity block respectively provided at both ends of the swing arm. The middle part of the swing arm is fixedly connected to the rotating shaft, so that the swing arm can swing around the rotating shaft as the center;
[0010] Wherein, the swing arm is arranged in the vertical direction in the initial state, and the center of gravity of the swing arm biases towards the gravity block, so that the touch member and the gravity block are respectively located at the upper and lower ends of the swing arm; and, the sensor is arranged corresponding to the swing arm in the initial state.
[0011] In a preferred embodiment of the present invention, a technical solution for the specific structural setting of the swing arm is provided.
[0012] In this preferred embodiment, the trigger is a pulley structure, and the pulley structure and the swing arm are rotatably connected.
[0013] Furthermore, the top of the pulley structure is higher than the top of the swing arm.
[0014] In another preferred embodiment of the present invention, a technical solution for the specific structural setting of the sensor is provided.
[0015] In this preferred embodiment, the sensor is fixed to the bracket via a mounting bracket, and the sensor is arranged corresponding to the swing arm region between the trigger and the rotating shaft.
[0016] Furthermore, the sensor is a displacement sensor or a proximity switch, and a sensing surface of the displacement sensor or the proximity switch is arranged toward the swing arm.
[0017] In another preferred embodiment of the present invention, a technical solution for the specific structural arrangement of the trigger and the gravity block is provided.
[0018] In this preferred embodiment, the weight of the gravity block is greater than the weight of the triggering member, so that the center of gravity of the swing arm is biased toward the gravity block.
[0019] Furthermore, the distance between the gravity block and the rotating shaft is greater than the distance between the triggering member and the rotating shaft, so that the center of gravity of the swing arm is biased toward the gravity block.
[0020] In another preferred embodiment of the present invention, a technical solution for the transmission design and waterproof design of the rotating shaft is provided.
[0021] In this preferred embodiment, a bearing seat is fixedly provided on the bracket, at least a part of the structure of the rotating shaft is inserted into the bearing seat, and a bearing is provided between the rotating shaft and the bearing seat.
[0022] Furthermore, the swing arm is also provided with a water retaining cover, and the water retaining cover is located on the top of the rotating shaft and the bearing seat.
[0023] Furthermore, a waterproof ring is sleeved on the rotating shaft, and the waterproof ring is arranged close to the bearing seat.
[0024] In summary, the working principle of the high-precision anti-interference detection mechanism provided by the utility model is as follows:
[0025] The high-precision anti-interference detection mechanism is installed below the device through a bracket. In the initial state, the center of gravity of the swing arm biases towards the gravity block. The trigger and the gravity block are respectively located at the upper and lower ends of the swing arm. Under the action of the gravity of the gravity block, the swing arm is arranged in the vertical direction, and the top of the trigger slightly protrudes above the conveyor belt of the device. At this time, the sensor is facing the swing arm, and its sensing surface can sense the presence of the metal swing arm. When glass passes on the conveyor belt, the glass contacts the trigger, driving the swing arm to swing in the direction of glass conveyance. When the swing arm swings to a certain amplitude, the sensor cannot sense the swing arm and obtains a corresponding electrical signal. After the glass passes, the swing arm returns to the initial vertical state under the action of the gravity of the gravity block, and the sensor faces the swing arm again, sensing the presence of the swing arm again. By cycling in this way, the front and rear positions of the glass passing on the device can be detected, and the number of passing glasses can be counted and memorized by detecting the swing state of the swing arm through the sensor.
[0026] Compared with the prior art, the above structural design method has at least the following technical effects:
[0027] The present utility model converts the movement of the glass on the conveyor belt into the swing of the swing arm, and detects the swing state of the swing arm through the sensor, thereby obtaining the front and rear positions and the passing quantity information of the glass. Compared with the design method of directly detecting the glass by emitting light sources through photoelectric sensors in the prior art, the sensor of the present utility model is only used to detect the position information of the swing arm, so it will not be affected by impurities such as water stains on the glass, has high detection accuracy and will not have false detection situations, improving the processing accuracy of the device.

[0036] Embodiment 1
[0037] See Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the high-precision anti-interference detection mechanism includes a bracket 1 and a swing arm 3. A sensor 4 is fixedly installed on the bracket 1, and a rotatable rotating shaft 2 is provided on the bracket 1. Touching members 31 and gravity blocks 32 are respectively provided at both ends of the swing arm 3, and the middle part of the swing arm 3 is fixedly connected to the rotating shaft 2 so that the swing arm 3 can swing around the rotating shaft 2. Among them, the "middle part of the swing arm 3" described in this embodiment does not refer to the exact middle position of the swing arm 3, but refers to the middle area of the swing arm 3 between the touching member 31 and the gravity block 32, that is, the swing center of the swing arm 3 can be located at the exact middle of the swing arm 3, or can be set close to the touching member 31 or close to the gravity block 32, and the specific setting position is determined according to the actual installation situation.
[0038] See Figure 2 As shown, the swing arm 3 is arranged in the vertical direction in the initial state, and the center of gravity of the swing arm 3 is biased towards the gravity block 32, so that the touching member 31 and the gravity block 32 in the initial state are respectively located at the upper and lower ends of the swing arm 3, and the sensor 4 is arranged corresponding to the swing arm 3 in the initial state.
[0039] The working principle of the high-precision anti-interference detection mechanism of the present utility model is as follows:
[0040] 1) The high-precision anti-interference detection mechanism is installed below the conveyor belt of the processing equipment through the bracket 1. In the initial state, the center of gravity of the swing arm 3 is biased towards the gravity block 32. Under the action of the gravity of the lower gravity block 32, the swing arm 3 is arranged in the vertical direction, and the top of the touching member 31 above the swing arm 3 slightly protrudes above the conveyor belt of the equipment. At this time, the sensor 4 on the bracket 1 is facing the swing arm 3, and the sensing surface of the sensor 4 can sense the presence of the swing arm 3.
[0041] 2) When glass passes on the conveyor belt, the glass contacts the trigger member 32, driving the swing arm 3 to swing in the direction of glass conveyance. When the swing arm 3 swings to a certain amplitude, the sensor 4 cannot sense the swing arm 3, and at this time, the sensor 4 generates a corresponding electrical signal.
[0042] 3) After the glass passes, the swing arm 3 swings back to its initial upright state under the gravity of the gravity block 32, the sensor 4 faces the swing arm 3 again, and the presence of the swing arm 3 is sensed again.
[0043] 4) In this cycle, when multiple pieces of glass pass, the front and back positions of the glass passing on the device and the counting and memorization of the number of passing glass can be realized by detecting the swing state of the swing arm 3 by the sensor 4.
[0044] Therefore, the high-precision anti-interference detection mechanism of the present utility model converts the movement of the glass on the conveyor belt into the swing of the swing arm 3, and detects the swing state of the swing arm 3 through the sensor 4, thereby obtaining the front and back positions and the passing quantity information of the glass. Compared with the design method of directly detecting the glass by emitting light sources through photoelectric sensors in the prior art, the detection mechanism of the present utility model is only used to detect the position information of the swing arm 3, so it will not be affected by impurities such as water stains on the glass, has high detection accuracy and will not have false detection situations, improving the processing accuracy of the device.
[0045] Embodiment 2
[0046] In the second embodiment of the present utility model, on the basis of the first embodiment, a technical solution for the specific structural setting of the swing arm 3 is provided.
[0047] When the glass on the conveyor belt passes, the edge and bottom surface of the glass directly contact the trigger member 3. During the movement of the glass, the trigger member 3 continuously rubs against the glass, which easily causes frictional damage to the glass. Therefore, in the technical solution of this embodiment, refer to Figure 1 and Figure 2 As shown, the trigger member 31 is set as a pulley structure, and this pulley structure is rotatably connected to the swing arm 3. Specifically, the outer surface of the pulley structure is smoothly arranged. When the glass on the conveyor belt passes, the friction between the glass and the pulley structure is sliding friction, which can greatly reduce the frictional loss of the glass edge and bottom surface.
[0048] In a preferred solution of this embodiment, the top end of the pulley structure is set higher than the top end of the swing arm 3, ensuring that in the initial state, the glass can contact the pulley structure when passing on the conveyor belt, rather than directly contacting the swing arm 3, avoiding the influence and interference of the swing arm 3 on the sliding friction between the pulley structure and the glass, and avoiding the swing arm 3 directly contacting the glass, playing a role in protecting the glass.
[0049] Embodiment 3
[0050] In the third embodiment of the present utility model, on the basis of the first embodiment, a technical solution regarding the specific structural arrangement of the sensor 4 is provided.
[0051] See Figure 1 As shown, in an alternative solution of this embodiment, the sensor 4 is fixed to the bracket 1 through the mounting bracket 41, and the sensor 4 is arranged corresponding to the swing arm 3 area between the trigger member 31 and the rotating shaft 2, that is, the sensor 4 corresponds to the upper area of the swing arm 3 in the initial state. Since the gravity block 32 is heavy and large in volume, the gravity block 32 requires a relatively large installation space. If the sensor 4 is arranged in the swing arm 3 area between the sensor 4 and the gravity block 32 and the rotating shaft 2, that is, corresponding to the lower area of the swing arm 3, it will occupy too much of the lower installation space, resulting in an overly long lower half of the swing arm 3. Therefore, considering the space design factors, the sensor 4 of the present utility model is arranged at a position corresponding to the upper area of the swing arm 3. In addition, arranging the sensor 4 in the upper area can also facilitate operations such as maintenance and replacement by the user.
[0052] In another alternative solution of this embodiment, the sensor 4 can adopt a displacement sensor or a proximity switch, and the sensing surface of the displacement sensor or the proximity switch is arranged facing the swing arm 3 in the initial state for detecting the swinging state of the swing arm 3. In the initial state, the sensing surface can sense the presence of the swing arm 3. When glass passes on the conveyor belt, the glass contacts the trigger member 31 and drives the swing arm 3 to swing in the direction of glass conveyance. When the swing arm 3 swings to a certain amplitude, the sensing surface can no longer sense the swing arm 3, thereby generating a corresponding electrical signal to achieve the detection of the front and rear positions and the passing quantity of the glass.
[0053] Embodiment 4
[0054] In the fourth embodiment of the present utility model, on the basis of the first embodiment, a technical solution regarding the specific structural arrangement of the trigger member 31 and the gravity block 32 is provided.
[0055] In an alternative solution of this embodiment, the weight of the gravity block 32 is greater than the weight of the trigger member 31, so that the center of gravity of the swing arm 3 biases towards the gravity block 32. Through the above structural design method, it can be ensured that in the case of no glass passing, the swing arm 3 in the initial state can be arranged vertically under the action of the gravity block 32 with a relatively large weight, preventing the swing arm 3 from having excessive swinging phenomena, and further avoiding the phenomenon that the swing arm 3 accidentally triggers the sensor 4, thereby further improving the detection accuracy.
[0056] In another optional solution of this embodiment, the center of gravity of the swing arm 3 can be offset by setting different arm lengths in the upper and lower sections. Specifically, the distance from the gravity block 32 to the rotating shaft 2 is set to be greater than the distance from the trigger 31 to the rotating shaft 2, so that the center of gravity of the swing arm 3 is biased toward the gravity block 32. Similarly, through the above structural design, when the weight of the gravity block 32 is not much greater than that of the trigger 31 or the weight of the gravity block 32 is close to that of the trigger 31, it can still be ensured that the swing arm 3 in the initial state can be set in the vertical direction to prevent the swing arm 3 from swinging excessively.
[0057] Example 5
[0058] In the fifth embodiment of the present utility model, a technical solution for the transmission design and waterproof design of the rotating shaft 2 is provided on the basis of the first embodiment.
[0059] See also Figure 1 - Figure 3 As shown, in the technical solution of this embodiment, a bearing seat 5 is also fixedly provided on the bracket 1, at least part of the structure of the rotating shaft 2 is inserted in the bearing seat 5, and a bearing 51 is provided between the rotating shaft 2 and the bearing seat 5. Among them, one end of the bearing seat 5 is fixedly installed on the bracket 1, and the other end is provided with an opening for the rotating shaft 2 to be inserted, and a plurality of bearings 51 are provided inside. After the rotating shaft 2 is inserted into the bearing seat 5, it cooperates with the bearings 51, so that the rotating shaft 2 can be rotatably mounted on the bracket 1, that is, the swing arm 3 can be swingably mounted on the processing equipment. In addition, the bearing seat 5 and the bearing 51 are used to provide structural support for the rotation and swing of the rotating shaft 2, thereby reducing the wear on the rotating shaft 2.
[0060] See also Figure 1 and Figure 2 As shown, in a preferred solution of this embodiment, the swing arm 3 is also provided with a water retaining cover 6, and the water retaining cover 6 is located on the top of the rotating shaft 2 and the bearing seat 5. The water retaining cover 6 is set as an arc-shaped cover structure, which is used to block the entrance area of the rotating shaft 2 inserted into the bearing seat 5. Specifically, since the high-precision anti-interference detection mechanism of the utility model is installed below the conveyor belt, an opening needs to be opened for the trigger 31 on the swing arm 3 to extend. When the glass passes by, if there are impurities such as water stains, it is easy to fall from the opening onto the rotating shaft 2 and the bearing seat 5, thereby affecting the swinging motion of the swing arm 3 and even affecting the service life of the transmission structure. Therefore, by setting the water retaining cover 6, impurities such as sewage can be effectively prevented from falling into the rotating shaft 2 and the bearing seat 5, thereby improving the service life of the structure.
[0061] In order to further enhance the waterproof performance of the rotating shaft 2 and the bearing seat 5, in another preferred embodiment of the present invention, see Figure 3 As shown, a waterproof ring 7 is sleeved on the rotating shaft 2, and the waterproof ring 7 is arranged close to the bearing seat 5. Specifically, the waterproof ring 7 is used to seal the gap between the rotating shaft 2 and the entrance of the bearing seat 5, thereby preventing external liquids and other impurities from entering the interior of the bearing seat 5 and the bearing 51.
[0062] In summary, the high-precision anti-interference detection mechanism provided by the present utility model converts the movement of the glass on the conveyor belt into the swing of the swing arm 3, and detects the swing state of the swing arm 3 through the sensor 4, thereby obtaining the front and rear positions and the passing quantity information of the glass. Compared with the design method of directly detecting the glass by emitting light sources through photoelectric sensors in the prior art, the sensor of the present utility model is only used to detect the position information of the swing arm 3, so it will not be affected by impurities such as water stains on the glass, has high detection accuracy and will not have false detection situations, significantly improving the processing accuracy of the equipment.
[0063] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
