Description

Technical Field

[0001] This utility model relates to the field of glass chamfering, and in particular to an edge detection device. Background Technology

[0002] The existing glass position detection mechanism used in glass edging machines includes a servo motor, a swing arm, and a pulley. The servo motor is connected to one end of the swing arm, and the other end of the swing arm is equipped with a pulley. The pulley sequentially touches the front, side, and back of the glass, and the servo motor determines the position of the glass based on the swing angle of the swing arm. However, this structure requires the swing arm to rotate a large angle to touch the side, which is inefficient. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an edge detection device.

[0004] The technical solution of this utility model is as follows: it includes a support member that rotates around a rotation axis. The support member is equipped with a first roller and a second roller. The first central axis of the first roller and the second central axis of the second roller are both parallel to the rotation axis. The rotation axis, the first central axis, and the second central axis are all perpendicular to a horizontal plane. On the horizontal plane, the first central axis and the second central axis are both connected to the rotation axis by a line, and there is an included angle A between the two connecting lines.

[0005] When the front edge of the glass touches the first roller, the support can rotate so that the second roller can press against the side edge of the glass. As the glass moves and the second roller disengages from the side edge, the support can continue to rotate so that the second roller can press against the rear edge of the glass.

[0006] The edge detection device of this utility model has at least the following technical effects: by setting a first roller and a second roller on the support member, after the front edge touches the first roller, the second roller can be used to touch the side edge and the back edge of the glass, so as to realize the sequential positioning of the front edge, side edge and back edge of the glass, without the support member needing to rotate a large angle to position the side edge and the back edge, thus improving work efficiency.

[0007] Furthermore, the included angle A is 90°-270°.

[0008] Furthermore, the distance between the first central axis and the rotation axis is the same as the distance between the second central axis and the rotation axis.

[0009] Furthermore, the support member is disc-shaped.

[0010] Furthermore, both the first roller and the second roller are located at the upper or lower edge of the support member.

[0011] Furthermore, the support member is rod-shaped, and the first roller and the second roller are respectively provided at both ends of the support member.

[0012] Furthermore, the support member is capable of rotating in the first direction;

[0013] Alternatively, the support member can rotate along the first direction and a second direction opposite to the first direction.

[0014] Furthermore,

[0015] When the support rotates along the first direction and the second roller presses against the rear edge of the glass, the front edge of the next glass can touch the second roller, and after touching, the support can continue to rotate along the first direction, so that the first roller can sequentially touch the side edge and rear edge of the next glass as the next glass moves. As the support rotates along the first direction, the first roller and the second roller can alternately abut against the front edges of multiple glass pieces.

[0016] Alternatively, when the support rotates in the first direction and the second roller presses against the rear edge of the glass, the support can rotate in the second direction to a position where the first roller can be touched by the front edge of the next glass.

[0017] Furthermore, it also includes a rotating shaft, and the support has a mounting hole, with one end of the rotating shaft installed in the mounting hole.

[0018] Furthermore, the mounting hole is conical, and the shape of one end of the rotating shaft matches the shape of the mounting hole; several support members are provided on both the left and right sides of the glass.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0033] Reference Figure 1-5 As shown, the edge detection device provided in the embodiment of this utility model includes a support member 100, which rotates around a rotation axis. The support member 100 is equipped with a first roller 200 and a second roller 210. The first central axis of the first roller 200 and the second central axis of the second roller 210 are both parallel to the rotation axis. The rotation axis, the first central axis, and the second central axis are all perpendicular to a horizontal plane. On the horizontal plane, the first central axis and the second central axis are both connected to the rotation axis, and there is an included angle A between the two connecting lines. When the front edge 310 of the glass 300 touches the first roller 200, the support member 100 can rotate, so that the second roller 210 can press against the side edge 320 of the glass 300. As the glass 300 moves, after the second roller 210 disengages from the side edge 320, the support member 100 can continue to rotate, so that the second roller 210 can press against the rear edge 330 of the glass 300.

[0034] By providing a first roller 200 and a second roller 210 on the support member 100, after the front edge 310 touches the first roller 200, the second roller 210 can be used to touch the side edge 320 and the rear edge 330 of the glass 300, so that the front edge 310, side edge 320 and rear edge 330 of the glass 300 are positioned sequentially, without the support member 100 needing to rotate a large angle to position the side edge 320 and the rear edge 330, thus improving work efficiency.

[0035] Specifically, the edge detection device also includes a detection drive device (not shown in the figure). The detection drive device includes a controller and a processor. The controller is connected to the support member 100, and the connection between the controller and the support member 100 is located between the first roller 200 and the second roller 210. The controller is used to collect the angular position information of the support member 100 and feed it back to the processor, and to drive the support member 100 to rotate in a direction away from the front edge 310 of the glass 300. The processor is used to calculate the position of the edge of the glass 300 based on the angular position information.

[0036] Specifically, the height of the first roller 200 and the second roller 210 is the same as the height of the glass 300.

[0037] like Figure 1-5 As shown, the detection method includes the following steps:

[0038] S1, Set the initial angle position of the support 100 (so that the first roller 200 is in front of the glass 300) and set a torque for the controller;

[0039] S2, the first piece of glass 300 begins to move towards the support member 100 (forward). When the front edge 310 of the glass 300 hits the first roller 200, due to the torque, the first roller 200 will be in close contact with the front edge 310 of the glass 300. At this time, the processor calculates the position of the front edge 310 of the glass 300 in real time based on the current angle position information of the support member 100 fed back by the controller.

[0040] S3, after calculating the position of the front edge 310 of the glass 300, drive the support 100 to rotate in a direction away from the front edge 310 (counterclockwise);

[0041] S4, when the second roller 210 rotates to the side edge 320 of the glass 300, the second roller 210 cannot continue to rotate because it is blocked by the side edge 320 of the glass 300. The second roller 210 will be in close contact with the side edge 320 of the glass 300. At this time, the processor calculates the position of the side edge 320 of the glass 300 in real time based on the current angle position information of the support member 100 fed back by the controller.

[0042] S5, the glass 300 continues to move forward. When the second roller 210 leaves the side edge 320 of the glass 300, since the second roller 210 is not blocked by the side edge 320 and is driven by the controller, the second roller 210 will be close to the rear edge 330 of the glass 300. At this time, the processor calculates the position of the rear edge 330 of the glass 300 in real time based on the current angle position information of the support member 100 fed back by the controller.

[0043] Furthermore, such as Figure 2 As shown, the included angle A is 90°-270°. Using this angle range improves work efficiency and simplifies the structure.

[0044] Specifically, the included angle A can also be 15°, 30°, 45°, 60°, 75°, 90°, 105°, 120°, 135°, 150°, 165°, 180°, 195°, 210°, 225°, 240°, 255°, or 270°.

[0045] Understandably, while ensuring that the edge of the glass 300 can be detected, the included angle A can be any angle greater than 0° and less than 360°.

[0046] Specifically, such as Figure 1 , 2As shown, the first roller 200 and the second roller 210 are symmetrically distributed (equivalent to an included angle A of 180°). This arrangement of the first roller 200 and the second roller 210 improves work efficiency and simplifies the structure.

[0047] Furthermore, such as Figure 1 As shown, the distance between the first central axis and the rotation axis is the same as the distance between the second central axis and the rotation axis. This simplifies the structure of the edge detection device.

[0048] Furthermore, the support member 100 is disc-shaped or rod-shaped, allowing it to adapt to different working environments.

[0049] Specifically, such as Figure 2 As shown, when the support member 100 is disc-shaped, the first roller 200 and the second roller 210 can be located on the upper or lower side of the edge of the support member 100; for example... Figure 6 As shown, when the support member 100 is rod-shaped, the first roller 200 and the second roller 210 can be respectively located at the ends, bottoms, or tops of the support member 100. It can be understood that the rod-shaped support member 100 can be a straight rod, a curved rod, or composed of two rod segments with an included angle between them. Preferably, the support member 100 is a straight rod, i.e., the included angle A is 180°.

[0050] Furthermore, the support member 100 is capable of rotating in the first direction;

[0051] Alternatively, the support member 100 can rotate in a first direction and a second direction opposite to the first direction.

[0052] For example, such as Figure 1 As shown, the support member 100 can rotate in a counterclockwise direction (first direction), or the support member 100 can rotate in both a counterclockwise (first direction) and a clockwise (second direction).

[0053] Specifically, when the support member 100 rotates in the first direction and the second roller 210 presses against the rear edge 330 of the glass 300, the front edge 310 of the next glass 300 can touch the second roller 210. After touching, the support member 100 can continue to rotate in the first direction so that the first roller 200 can touch the side edge 320 and the rear edge 330 of the next glass 300 in sequence as the next glass 300 moves. As the support member 100 continues to rotate in the first direction, the first roller 200 and the second roller 210 can alternately abut against the front edges 310 of multiple glass 300s.

[0054] Alternatively, when the support 100 rotates in the first direction and the second roller 210 presses against the rear edge 330 of the glass 300, the support 100 can rotate in the second direction so that the support 100 rotates to a position where the first roller 200 can be touched by the front edge 310 of the next glass 300.

[0055] Understandably, when the included angle A is greater than 120°, since the glass 300 does not interfere with the rotation of the support 100, the support 100 can rotate counterclockwise continuously; when the included angle A is less than 120°, since the included angle A is small, the glass 300 may interfere with the rotation of the support 100. Therefore, the support 100 first rotates counterclockwise and then clockwise to return to its original position, and then re-inspects the next glass to avoid the glass 300 interfering with the rotation of the support 100.

[0056] For example, when the included angle A is small, the edge detection device works along steps S1-S5. Before detecting the second glass, the support 100 rotates clockwise so that the first roller 200 returns to its original position, and the edge detection device re-detects the second glass along steps S1-S5.

[0057] When the included angle A is large, after the front edge 310 of the second glass 300 touches the second roller 210, the processor calculates the position of the front edge 310 of the second glass 300, and the controller drives the support 100 to rotate counterclockwise. The first roller 200 touches the side edge 320 and the rear edge 330 in sequence, realizing the position detection of the front edge 310, side edge 320 and rear edge 330 of the glass 300. When it is necessary to detect the third glass 300 or more glass 300, repeat steps S1-S5 and the above steps.

[0058] It is conceivable that a third roller can be set between the first roller 200 and the second roller 210. The third roller has an included angle A with the first roller and the second roller. The first roller 200, the third roller and the second roller 210 are set at intervals in a counterclockwise direction. When the front edge 310 of the first glass 300 touches the first roller 200, the support member 100 rotates. The second roller 210 touches the side edge 320 and the rear edge 330 of the first glass 300 in sequence. When detecting the second glass 300, the front edge 310 of the second glass 300 touches the second roller 210, and the third roller touches the side edge 320 and the rear edge 330 of the second glass in sequence. When detecting the third glass 300, the front edge 310 of the third glass 300 touches the third roller, and the first roller 200 touches the side edge 320 and the rear edge 330 of the third glass in sequence. If more glass needs to be detected, the above steps are repeated.

[0059] Furthermore, such as Figure 1 , 7As shown, it also includes a rotating shaft 400, and the support member 100 has a mounting hole 110, with one end of the rotating shaft 400 installed in the mounting hole 110. Specifically, the rotating shaft 400 is fixed to the support member 100 by screws.

[0060] Specifically, the controller is connected to the other end of the rotating shaft 400.

[0061] Specifically, the rotating shaft 400 is fixed to the support member 100 by screws.

[0062] Furthermore, such as Figure 1 , 7 As shown, the mounting hole 110 is tapered, and the shape of one end of the rotating shaft 400 matches the shape of the mounting hole 110. The tapered mounting hole 110 and the tapered rotating shaft 400 at one end cooperate to ensure that the roller 200 can accurately detect the position of the glass 300.

[0063] Furthermore, the controller is a servo motor (not shown in the figure). The servo motor can drive the support 100 to rotate, and the rotation angle of the support 100 can also be recorded by the encoder inside the servo motor, which facilitates cooperation with the processor.

[0064] Furthermore, several support members 100 are provided on both the left and right sides of the glass 300 to enable simultaneous detection of different edges of the glass 300.

[0065] Specifically, when there is one or more support members 100, the support members 100 are spaced apart in the front-to-back direction.

[0066] Although the technical solutions of this utility model have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these technical solutions without departing from the principles and spirit of this utility model, the scope of which is defined by the claims and their equivalents.
