Description

Technical Field

[0001] The invention relates to the technical field of edge grinding machines, and in particular to a residual detection device for edge grinding machines. Background Art

[0002] In the existing glass edge grinding machine, the residual detection device for detecting the width of the glass generally adopts a detection wheel for detection. When the glass passes through, the edge of the glass contacts the detection wheel, driving the detection wheel to move, thereby driving the swing arm to rotate, and the swing arm drives the rotating shaft to rotate, thereby driving the encoder output shaft to rotate, and then the encoder sends the residual data of the glass to the control system. After the glass has completely passed, the detection wheel is reset by the reset spring driving the rotating shaft to reset, thereby driving the swing arm and the detection wheel to reset, waiting for the arrival of the next piece of glass, and repeating the above working process.

[0003] However, since the residual detection action is reciprocating, the reset spring is prone to shaking under the action of external force, affecting the detection accuracy; in addition, the detection wheel will swing back and forth and reset during operation, so the reset spring is prone to stretching and deformation during long-term use. Over time, the elastic force is poor and it is not easy to reset. After the elastic force weakens during use, it also affects the reset position of the detection wheel and affects the detection accuracy of the detection wheel. Summary of the invention

[0004] In order to overcome at least one of the defects of the prior art described above, the present invention provides a residual detection device for an edge grinding machine, which can reset the detection wheel on the swing arm by means of a first magnet and a second magnet that repel each other magnetically.

[0007] A detection seat, wherein a first magnet is provided on the detection seat;

[0008] The detection mechanism comprises an angle detector, a detection wheel, a swing arm and a detection shaft, wherein the detection wheel is rotatably connected to one end of the swing arm, the other end of the swing arm is connected to the detection shaft and drives the detection shaft to rotate during the swinging process; the detection shaft is rotatably connected to the detection seat, the angle detector is mounted on the detection seat and is used to detect the rotation angle of the detection shaft; a second magnet is connected to the detection shaft, and the second magnet and the first magnet have magnetic repulsion;

[0009] The detection wheel is used to contact the glass during the glass conveying process to drive the swing arm to swing and link the detection axis to rotate around the first direction; the second magnet is used to approach the first magnet after the detection axis rotates around the first direction; the second magnet is used to be subjected to the repulsive force of the first magnet after approaching the first magnet, so as to drive the detection axis to rotate around the second direction and link the swing arm to reset.

[0010] Furthermore, a third magnet is provided on the detection seat, and the third magnet and the first magnet are arranged at intervals on the rotation track of the second magnet; the third magnet and the second magnet are magnetically attracted to each other.

[0011] Furthermore, the third magnet is spaced apart from the first magnet on both sides of the rotation track.

[0012] Furthermore, two third magnets are provided, and the two third magnets are spaced apart from the first magnets on both sides of the rotation track.

[0013] Furthermore, the detection seat is provided with a bearing seat, and the outer periphery of the detection shaft is provided with a detection disk, and the detection shaft is rotatably connected to the bearing seat through a first bearing; the top end of the detection shaft extends out through the top end of the detection seat and forms a detection end; the detection end is connected to the angle detector; the detection disk is used to rotatably cover the bottom end of the bearing seat when the detection shaft is connected to the bearing seat; the first magnet is arranged on the bearing seat; the second magnet is arranged on the detection disk.

[0014] Furthermore, the detection wheel is connected to the swing arm via a connecting shaft; one end of the connecting shaft is rotatably connected to the detection wheel via a second bearing; and the other end of the connecting shaft is connected to the swing arm.

[0015] Furthermore, a flat hole is provided on the swing arm; a flat surface is provided on the outer periphery of the connecting shaft, and the connecting shaft is connected to the flat hole so that the flat surface and the flat hole are limitedly abutted.

[0016] Furthermore, it also includes a fixing seat, and the detection seat can be slidably installed on the fixing seat.

[0017] Furthermore, a sliding groove is provided on the fixing seat, and an adjustment hole is provided on the detection seat; a connecting bolt is slidably inserted into the adjustment hole; the connecting bolt passes through the adjustment hole and is used to be screwed to the fixing seat to loosen or fix the detection seat.

[0018] Furthermore, an adjusting screw is provided on the fixing seat, the adjusting screw is threadedly connected to the detection seat, and an adjusting wheel is provided at the end of the adjusting screw away from the detection seat, and the adjusting wheel is used to drive the adjusting screw to rotate.

[0019] In summary, the present invention has the following technical effects:

[0020] In the present application, the magnetic repulsion force between the first magnet and the second magnet is determined by the magnetism of the first magnet and the second magnet themselves. Therefore, the acting force between the two is more stable than the elastic force provided by the spring in the prior art. Therefore, the detection axis needs to overcome the magnetic repulsion force to be stable when the detection wheel detects swing. Therefore, the swing angle of the detection axis will not cause erroneous detection results due to unstable elastic force, thereby improving the detection accuracy.

[0021] In addition, when the detection shaft is reset, the magnetic repulsion between the second magnet on the detection shaft and the first magnet on the detection seat realizes the resetting action of the detection wheel, which is also stable compared to the elastic force provided by the spring. If the elastic force provided by the spring is used to achieve resetting, the elastic force of the spring will weaken during the reciprocating stretching and compression process, and the position after reset will change after long-term use, resulting in affected detection accuracy. However, if resetting is carried out by magnetic repulsion, the force is stable and the reset position is accurate, thereby improving detection accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0031] See also Figure 1-Figure 5 The present invention discloses a residual detection device for an edge grinding machine, comprising a detection seat 10 and a detection mechanism, wherein a first magnet 11 is arranged on the detection seat 10. The detection mechanism comprises an angle detector 50, a detection wheel 30, a swing arm 20 and a detection shaft 40, wherein the detection wheel 30 is rotatably connected to one end of the swing arm 20, and the other end of the swing arm 20 is connected to the detection shaft 40, and the detection shaft 40 is rotatably mounted on the detection seat 10. Since the detection shaft 40 is connected to the swing arm 20, the swing arm 20 can drive the detection shaft 40 to rotate during the swinging process. The above-mentioned angle detector 50 is mounted on the detection seat 10 and is used to detect the rotation angle of the detection shaft 40, and a second magnet 41 is connected to the detection shaft 40, and the second magnet 41 and the first magnet 11 are magnetically repelled from each other.

[0032] Specifically, the detection wheel 30 contacts the glass during the glass conveying process to drive the swing arm 20 to swing, and links the detection shaft 40 to rotate around the first direction; after the detection shaft 40 rotates around the first direction, the second magnet 41 can approach the first magnet 11, and the second magnet 41 is repelled by the first magnet 11 after approaching the first magnet 11, so as to drive the detection shaft 40 to rotate around the second direction, and links the swing arm 20 to reset.

[0033] On the basis of the above structure, when the residual amount detection device of the edge grinding machine of the present invention is used, the residual amount detection device is installed on the body of the glass edge grinding machine and is located on the side of the conveying assembly of the glass edge grinding machine:

[0034] When the glass is being edged normally, a certain margin is required on the side of the glass. When the glass is transported to the edge grinding position by the conveying assembly of the glass edge grinding machine, if the side margin of the glass is consistent with the margin value set by the machine body, the glass is tangent to the wheel surface of the detection wheel 30 when being transported by the conveying assembly of the glass edge grinding machine. The detection wheel 30 and the side of the glass are rolled together to guide the glass to be transported to the edge grinding position.

[0035] If the side margin of the glass exceeds the margin value set by the machine body, the side of the glass will be in close contact with the wheel surface of the detection wheel 30 when it is conveyed to the position of the margin detection device, and will drive the detection wheel 30 to move along the conveying direction during the glass conveying assembly. In this way, the detection wheel 30 will drive the swing arm 20 to swing. After the swing arm 20 swings, the detection shaft 40 at the other end of the swing arm 20 will also rotate relative to the detection seat 10 under the action of the swing arm 20. In this way, the angle detector 50 can detect the rotation of the detection shaft 40, and send an angle detection signal when the rotation angle of the detection shaft 40 is detected, thereby playing a role in detecting the margin of the side of the glass.

[0036] In this embodiment, the detection shaft 40 rotates around the first direction during the swinging process of the swing arm 20, so that the second magnet 41 on the detection shaft 40 can overcome the repulsive force between the first magnet 11, thereby moving close to the first magnet 11. After the residual detection is completed, it is necessary to reset the detection wheel 30 to perform the side residual detection of the next glass. At this time, the detection wheel 30 is not subjected to external force in the absence of the conveying force of the conveying component. The first magnet 11 on the above-mentioned detection seat 10 and the second magnet 41 on the detection shaft 40 magnetically repel each other. Under the action of the magnetic repulsive force, the second magnet 41 on the detection shaft 40 moves away from the first magnet 11, thereby driving the detection shaft 40 to rotate in the second direction (opposite to the first direction), thereby driving the swing arm 20 to reset, and then driving the detection wheel 30 to reset.

[0037] That is, in the present application, the magnetic repulsion force between the first magnet 11 and the second magnet 41 is determined by the magnetism of the first magnet 11 and the second magnet 41 themselves, and thus the acting force therebetween is more stable than the elastic force provided by the spring in the prior art. Therefore, the detection shaft 40 needs to overcome the magnetic repulsion force to be stable when the detection wheel 30 detects the swing. Therefore, the swing angle of the detection shaft 40 will not cause erroneous detection results due to unstable elastic force, thereby improving the detection accuracy.

[0038] In addition, when the detection shaft 40 is reset, the magnetic repulsion between the second magnet 41 on the detection shaft 40 and the first magnet 11 on the detection seat 10 realizes the reset action of the detection wheel 30, which is also stable compared to the elastic force provided by the spring. If the elastic force provided by the spring is used to achieve reset, the elastic force of the spring will weaken during the reciprocating stretching and compression process, and the position after reset will change after long-term use, resulting in the detection accuracy being affected. However, when resetting is performed by magnetic repulsion, the force is stable and the reset position is accurate, thereby improving the detection accuracy.

[0039] It should be noted that how to convert the swing angle of the swing arm 20 driven by the detection wheel 30 into the specific residual value of the glass is implemented by the existing edge grinding machine control system, which is not the content to be protected by this application and will not be described in detail here.

[0040] Furthermore, in this embodiment, a third magnet 14 may be further provided on the detection seat 10, and the third magnet 14 and the first magnet 11 are spaced apart on the rotation track of the second magnet 41, and the third magnet 14 and the second magnet 41 are magnetically attracted to each other. The position where the third magnet 14 is provided is the starting position of the rotation of the detection shaft 40, that is, when the residual detection device is in the initial state of detection, the second magnet 41 on the detection shaft 40 can be magnetically attracted to the third magnet 14 on the detection seat 10, and under the action of the magnetic attraction, the detection shaft 40 remains stationary at this position, so that the swing starting position of the swing arm 20 is relatively stable and is not easy to swing under the action of external force.

[0041] When the side margin of the glass exceeds the margin value set by the machine body, the side of the glass is in close contact with the wheel surface of the detection wheel 30, and the glass can drive the detection wheel 30 to move together, driving the swing arm 20 to swing. After the swing arm 20 swings, the detection shaft 40 at the other end of the swing arm 20 will overcome the magnetic attraction between the third magnet 14 and the second magnet 41 under the action of the swing arm 20. Thereafter, the detection shaft 40 starts to rotate, overcomes the magnetic repulsion between the first magnet 11 and the second magnet 41, and then moves toward the first magnet 11 on the rotation trajectory. In this way, the angle detector 50 can detect the rotation of the detection shaft 40, and send an angle detection signal when the rotation angle of the detection shaft 40 is detected, thereby playing a role in detecting the margin of the side of the glass.

[0042] After the detection action is completed, the second magnet 41 on the detection shaft 40 is reset by the magnetic repulsion force of the first magnet 11 on the detection seat 10, and the magnetic attraction between the second magnet 41 and the third magnet 14 is superimposed, so that the second magnet 41 is subjected to a faster resetting force, and a quick resetting can be achieved. After the detection shaft 40 is reset, the second magnet 41 will not rotate again after being attracted by the third magnet 14, so there will be no excessive resetting rotation. That is, in addition to providing a superimposed force to achieve a quick resetting, the third magnet 14 can also be used as a fixed point for the starting point position. Each detection action of the detection shaft 40 can start from the position of the third magnet 14, so the detection result is more accurate.

[0043] Furthermore, the first magnets 11 can be spaced apart on both sides of the rotation track of the third magnet 14, and the second magnet 41 of the detection shaft 40 can be magnetically matched with the third magnet 14 located in the middle position, so that the glass can move in one direction under the action of the conveying component, driving the swing arm 20 to rotate in one direction, and the second magnet 41 can be separated from the third magnet 14 and move toward the first magnet 11 on one side, and reset by the magnetic repulsion force of the first magnet 11 on the side. If the glass moves in the other opposite direction under the action of the conveying component, driving the swing arm 20 to rotate in another direction, the second magnet 41 can be separated from the third magnet 14 and move toward the first magnet 11 on the other side, and reset by the magnetic repulsion force of the first magnet 11 on the corresponding side, that is, by arranging two first magnets 11 on both sides of the third magnet 14, it can be applied to glass edge grinding machines conveyed in different directions, without adjustment according to the conveying direction, and has a wider range of applications.

[0044] More specifically, there are two third magnets 14, and the third magnets 14 are distributed on both sides of the rotation track of the detection shaft 40, which are symmetrical, and the two third magnets 14 are spaced apart with the first magnets 11 on both sides of the rotation track. The second magnets 41 are provided on both sides of the symmetrical detection shaft 40, so that no matter which direction the detection wheel 30 swings, the symmetrical sides of the detection shaft 40 are acted on by the second magnets 41, the third magnets 14 and the first magnets 11 respectively, and act on both sides at the same time, so that the force distribution is even, and the reset process and rotation detection process of the detection shaft 40 are smoother.

[0045] It should be noted that the first magnet 11 , the second magnet 41 and the third magnet 14 can be permanent magnets in the prior art, or electromagnets in the prior art, and the selection is made according to actual needs.

[0046] Furthermore, since the residual detection is realized by using the angle detector 50 to detect the rotation of the detection shaft 40 linked to the swing arm 20, the rotation process of the detection shaft 40 needs to be kept smooth. Therefore, a bearing seat 12 can be provided on the detection seat 10, and a detection disk 42 is provided on the outer periphery of the detection shaft 40. The above-mentioned detection shaft 40 is rotatably connected to the bearing seat 12 through the first bearing 13. In this way, the rotation of the detection shaft 40 is guided by the first bearing 13, so that the rotation is smooth, the rotation process of the detection shaft 40 is smooth, and the detection result is more accurate.

[0047] Specifically, on the basis of the structure of the bearing seat 12, the top end of the above-mentioned detection shaft 40 extends out through the top end of the detection seat 10 and forms a detection end, and the detection end is connected to the angle detector 50. Taking the angle detector 50 as an encoder as an example, the detection end of the detection shaft 40 can be connected to the shaft of the encoder, so that angle detection can be realized by the encoder.

[0048] A detection disk 42 is provided on the detection shaft 40. When the detection shaft 40 is connected to the bearing seat 12, the detection disk 42 can rotate to cover the bottom end of the bearing seat 12. The detection disk 42 can rotate in a sealed manner with the bottom end of the bearing seat 12 through a seal, so that the inside of the bearing seat 12 can be kept sealed and dustproof.

[0049] Based on this structure, the first magnet 11 is disposed on the bearing seat 12 , and the second magnet 41 is disposed on the detection disk 42 .

[0050] Of course, a bearing cavity may be provided in the bearing seat, the detection shaft passing through the bearing seat is rotatably connected in the bearing cavity by two first bearings spaced apart vertically, the first magnet is provided at the bottom end of the bearing cavity, and the detection disk is sealed at the bottom end of the bearing cavity.

[0051] Furthermore, in order to facilitate the installation of the detection wheel 30 and the swing arm 20, the detection wheel 30 is connected to the swing arm 20 via a connecting shaft 31; one end of the connecting shaft 31 is rotatably connected to the detection wheel 30 via a second bearing 32, and the other end of the connecting shaft 31 is connected to the swing arm 20. In this way, the detection wheel 30 can be pivotally matched with the connecting shaft 31 via the second bearing 32, and the rotation of the detection wheel 30 is smooth.

[0052] Furthermore, a flat hole can be provided on the swing arm 20, and a flat surface 311 can be provided on the outer periphery of the connecting shaft 31 accordingly. When the detection wheel 30 is installed, the connecting shaft 31 is connected to the flat hole so that the flat surface 311 and the flat hole are limitedly abutted against each other, so that the flat surface 311 can prevent the connecting shaft 31 and the swing arm 20 from rotating.

[0053] Furthermore, the margin detection device of the edge grinding machine in this embodiment also includes a fixed seat 70, and the detection seat 10 is slidably mounted on the fixed seat 70. The fixed seat 70 can be mounted on the body of the glass edge grinding machine and is located on the side of the conveying component. The sliding of the detection seat 10 adjusts the distance between the detection wheel 30 and the side of the conveying component. When the required margin is large, the sliding detection seat 10 is away from the side of the conveying component, so that the distance becomes larger, so that the side margin of the reserved glass is larger and can contact the detection wheel 30. When the required margin is small, the sliding detection seat 10 is close to the side of the conveying component, so that the distance becomes smaller, so that the side margin of the reserved glass can contact the detection wheel 30 when it is small.

[0054] More specifically, a sliding groove is provided on the above-mentioned fixing seat 70, and an adjustment hole 15 is correspondingly provided on the detection seat 10. Specifically, a connecting bolt 60 is slidably inserted into the adjustment hole 15. The above-mentioned connecting bolt 60 is passed through the adjustment hole 15 and is used to be screwed to the fixing seat 70 to loosen or fix the detection seat 10.

[0055] When adjusting the position of the detection seat 10, the connecting bolt 60 can be rotated to loosen the detection seat 10 and the fixing seat 70. At this time, the detection seat 10 can guide the stable sliding of the detection seat 10 by the sliding cooperation between the connecting bolt 60 and the adjustment hole 15. After the position of the detection seat 10 is adjusted to the right position, the connecting bolt 60 is rotated to tighten and press the detection seat 10 on the fixing seat 70 to achieve stable assembly.

[0056] Specifically, a gasket may be provided between the connecting bolt 60 and the end surface of the detection seat 10 to increase the friction between the two, so that after the detection seat 10 is fixed, it is not easy to get loose.

[0057] Furthermore, in order to facilitate the adjustment of the sliding of the detection seat 10 on the fixed seat 70, an adjusting screw 80 may be provided on the fixed seat 70, the adjusting screw 80 is threadedly connected to the detection seat 10, and an adjusting wheel 81 is provided at the end of the adjusting screw 80 away from the detection seat 10, and the adjusting wheel 81 is used to drive the adjusting screw 80 to rotate. In this way, the adjusting wheel 81 can be rotated to drive the adjusting screw 80 to rotate, and the adjusting screw 80 and the detection seat 10 are threadedly matched, and at the same time, the connecting bolt 60 and the sliding of the adjusting hole 15 are matched, so that the detection seat 10 can move forward and backward to achieve position adjustment.

[0058] Of course, the adjusting screw 80 and the detection seat 10 can also be rotated together through the third bearing 82, so that the rotation of the adjusting screw 80 is smoother. In addition, when the adjusting screw 80 is not provided, the movement of the detection seat 10 can also be driven by other power output structures such as a cylinder, an oil cylinder or a screw transmission structure.

[0059] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
