Description

Technical Field

[0001] This utility model relates to the field of material handling equipment technology, and specifically to a material handling device. Background Technology

[0002] In the production of LCD panels, panel handling is a crucial step. During handling, panel connecting mechanisms sometimes pick up panels from a platform and transfer them to their designated positions. However, if there is a misalignment between the platform and the connecting mechanism, the mechanism may fail to accurately pick up the panel, leading to poor panel adhesion and the risk of panel drop. To mitigate this risk, current methods primarily rely on operators visually observing whether the connecting mechanism can accurately pick up the panel, then adjusting the position of the mechanism or platform. However, this approach impacts both handling and production efficiency. Utility Model Content

[0003] In view of the problems in the prior art, the purpose of this utility model is to provide a handling device that can automatically detect whether there is misalignment between the panel connection mechanism and the support platform, thereby improving the handling efficiency of the panel and saving manpower.

[0004] This utility model embodiment provides a conveying device, including:

[0005] The panel connection mechanism includes a fixed bracket and a positioning pin, wherein the positioning pin is movably connected to the fixed bracket along a first direction;

[0006] A support platform is disposed opposite to the panel connection mechanism along the first direction; the support platform is provided with positioning holes;

[0007] A sensor is disposed on at least one of the fixed bracket or the support platform; the sensor is configured to detect whether the positioning pin passes through the positioning hole when the fixed bracket moves toward the support platform.

[0008] The conveying device provided by this utility model has the following advantages:

[0009] By using sensors to detect whether the positioning pins pass through the positioning holes, the system can automatically detect whether the panel connecting mechanism and the support platform are aligned in the first direction. When the sensor detects that the panel connecting mechanism and the support platform are misaligned in the first direction, it can promptly prompt the operator to adjust the position of the support platform or the panel connecting mechanism to align them, thereby improving the efficiency of panel handling and saving manpower.

[0028] To address the problems in the prior art, this utility model provides a handling device, comprising: a panel connecting mechanism including a fixed bracket and a positioning pin, wherein the positioning pin is movably connected to the fixed bracket along a first direction; a support platform disposed opposite to the panel connecting mechanism along the first direction; the support platform having a positioning hole; and a sensor disposed on at least one of the fixed bracket or the support platform; wherein the sensor is configured to detect whether the positioning pin passes through the positioning hole when the fixed bracket moves toward the support platform.

[0029] This invention utilizes a sensor to detect whether the positioning pin passes through the positioning hole, thereby automatically detecting whether the panel connecting mechanism and the support platform are aligned in the first direction. When the sensor detects that the panel connecting mechanism and the support platform are misaligned in the first direction, it can promptly prompt the operator to adjust the position of the support platform or the fixed bracket to align them, thereby improving the efficiency of panel handling and saving manpower.

[0030] The conveying device provided by this utility model will be explained in detail below with reference to specific embodiments.

[0031] Figure 1 A schematic diagram of a conveying device provided in an embodiment of the present invention is shown; Figure 2 This is a schematic diagram of a support platform provided in an embodiment of the present utility model; Figure 3 This is a schematic diagram of a panel connection mechanism provided in an embodiment of the present utility model; Figure 4 This is a partial schematic diagram of a panel connection mechanism provided in an embodiment of this utility model. Figures 1 to 4 As shown, the conveying device includes a panel connection mechanism 10, a support platform 20, and a sensor 30.

[0032] Specifically, the panel connecting mechanism 10 includes a fixed bracket 11 and a positioning pin 12, with the positioning pin 12 movably connected to the fixed bracket 11 along a first direction. Here, the first direction is the up-down direction as seen on paper. The support platform 20 is arranged opposite to the panel connecting mechanism 10 along the first direction, and the support platform 20 is provided with a positioning hole 21; the sensor 30 is located on the side of the fixed bracket 11 away from the support platform 20; the sensor 30 is configured to detect whether the positioning pin 12 passes through the positioning hole 21 when the fixed bracket 11 moves toward the support platform 20.

[0033] Specifically, when the fixed bracket 11 moves towards the support platform 20, the positioning pin 12 moves along with it. When the positioning pin 12 aligns with the positioning hole 21, it passes through the hole 21 as the fixed bracket 11 approaches the support platform 20. However, when the positioning pin 12 is misaligned with the hole 21, the positioning pin 12 abuts against the support platform 20 as the fixed bracket 11 moves closer to it. In this case, the positioning pin 12 no longer moves with the fixed bracket 11 towards the support platform 20, and the end of the positioning pin 12 away from the support platform 20 moves further away from both the fixed bracket 11 and the support platform 20.

[0034] Therefore, in some embodiments, the sensor 30 can determine whether the positioning pin 12 moves continuously with the fixing bracket 11 as the positioning pin 12 moves closer, and thus determine whether the positioning pin 12 passes through the positioning hole. If the positioning pin 12 descends a certain distance and does not move downward with the fixing bracket 11, it indicates that the positioning pin 12 has not passed through the positioning hole 21; otherwise, it indicates that the positioning pin 12 has passed through the positioning hole 21.

[0035] Furthermore, such as Figure 4As shown, in some embodiments, the sensor 30 is disposed on the side of the fixed bracket 11 opposite to the support platform 20. The sensor 30 includes a transmitter and a receiver disposed opposite to each other. When the fixed bracket 11 moves along the first direction and the positioning pin 12 does not pass through the positioning hole 21, at least a portion of the structure of the positioning pin 12 is placed between the transmitter and the receiver. When a portion of the structure of the positioning pin 12 is placed between the transmitter and the receiver, the receiver is obstructed when receiving the signal transmitted by the transmitter. The signal received by the receiver changes, indicating that the positioning pin 12, after descending a certain distance, does not descend further but instead abuts against the support platform 20. Therefore, it can be determined that there is a misalignment between the panel connecting mechanism 10 and the support platform 20.

[0036] Furthermore, in another embodiment, the sensor 30 is disposed on the side of the support platform 20 away from the fixed bracket 11.

[0037] refer to Figure 1 When the positioning pin 12 passes through the positioning hole 21, part of the structure can pass through the positioning hole 21. When the sensor 30 located on the side of the support platform 20 away from the fixed bracket 11 detects the positioning pin 12, it can be determined that the positioning pin 12 passes through the positioning hole 21. Conversely, if the sensor 30 does not detect the positioning pin 12, it can be determined that the positioning pin 12 does not pass through the positioning hole 21.

[0038] Specifically, when the sensor 30 is located on the side of the support platform 20 away from the fixed bracket 11, the sensor 30 includes a transmitter and a receiver arranged opposite each other. When the fixed bracket 11 moves along the first direction and the positioning pin 12 passes through the positioning hole 21, at least a portion of the structure of the positioning pin 12 is positioned between the transmitter and the receiver. When a portion of the structure of the positioning pin 12 is positioned between the transmitter and the receiver, the receiver is obstructed when receiving the signal transmitted by the transmitter. The change in the signal received by the receiver indicates that the positioning pin 12 has passed through the positioning hole 21. Therefore, it can be determined that the panel connecting mechanism 10 corresponds to the support platform 20 and there is no misalignment.

[0039] It should be noted that the sensor 30 can be installed on at least one of the fixed bracket 11 and the support platform 20, depending on the specific actual needs. When the sensor 30 is installed on both the fixed bracket 11 and the support platform 20, it can also prevent the inability to automatically detect whether the positioning pin 12 has passed through the positioning hole 21 if one of the sensors 30 is damaged, thus providing a double guarantee for the automatic detection of whether the positioning pin 12 has passed through the positioning hole 21.

[0040] Furthermore, in this embodiment of the invention, the sensor 30 is a photoelectric sensor. For example, the photoelectric sensor 30 can be an active infrared sensor, in which the transmitter emits infrared light signals, but it is not limited to this.

[0041] Furthermore, such as Figure 4 As shown, in some embodiments, the fixed bracket 11 is provided with a mounting hole, and the positioning pin 12 includes a positioning rod 121 and a first protrusion 122 extending outward along the axial direction away from the positioning rod 121. The first protrusion 122 is located at the first end of the positioning rod 121; the second end of the positioning rod 121 passes through the mounting hole, and the first protrusion 122 abuts against the side of the fixed bracket 11 away from the support platform 20. The first protrusion 122 is mainly provided to confine the positioning rod 121 within the mounting hole before it contacts the support platform 20. Further, the diameter of the first protrusion 122 is larger than the diameter of the mounting hole, and the diameter of the positioning rod 121 is smaller than the diameter of the mounting hole, thereby enabling the positioning pin 12 to be movably connected to the fixed bracket 11 in the first direction.

[0042] Furthermore, in some embodiments, the positioning hole 21 is a circular hole or a rectangular hole. However, the shape of the positioning hole 21 is not limited to this and can be set according to actual needs.

[0043] Furthermore, in some embodiments, the positioning pin 12 further includes a second protrusion (not shown in the figure), disposed at the second end of the positioning rod 121, and extending outward along the axial direction away from the positioning rod 121; when the fixed bracket 11 moves in the first direction, the first protrusion 122 abuts against the fixed bracket 11; or, the second protrusion abuts against the fixed bracket 11. As can be seen from the above description, the first protrusion 122 and the second protrusion are respectively disposed on both sides of the mounting hole. When the positioning pin 12 is not abutting against the support platform 20, the first protrusion 122 abuts against the first side of the mounting hole, and the second protrusion does not directly contact the fixed bracket 11; while when the positioning pin 12 abuts against the support platform 20, when the fixed bracket 11 moves downward a certain distance, the first protrusion 122 will move relative to the first side away from the mounting hole, and thus no longer abut against the fixed bracket 11, while the second protrusion will move relative to the second side closer to the mounting hole, and thus abut against the fixed bracket 11. The second protrusion can limit the upward movement of the positioning rod 121. When the second protrusion abuts against the fixed bracket 11, the movement of the fixed bracket 11 can be stopped, so that when the positioning pin 12 abuts against the bearing platform 20, it does not need to move downward excessively.

[0044] Furthermore, in some embodiments, the second protrusion is detachably connected to the positioning rod 121. When assembling the positioning pin 12 onto the fixed bracket 11, the positioning rod 121 is first passed through the mounting hole, and then the second protrusion is installed, which can improve the efficiency of installing the positioning pin 12.

[0045] Furthermore, in some embodiments, the diameter of the second protrusion is larger than the diameter of the mounting hole of the fixing bracket 11. The second protrusion can act as a limit, so that the fixing bracket 11 does not need to move down excessively to determine that the positioning pin 12 has abutted against the support platform 20.

[0046] Furthermore, in some embodiments, the panel connecting mechanism 10 also includes a plurality of suction cups (not shown in the figure) evenly arranged on the fixed bracket 11. The suction cups provide uniform suction force when picking up the liquid crystal panel, improving the stability of picking up the liquid crystal panel.

[0047] The conveying device provided by this utility model has the following advantages:

[0048] By using sensors to detect whether the positioning pins pass through the positioning holes, the system can automatically detect whether the panel connecting mechanism and the support platform are aligned in the first direction. When the sensor detects that the panel connecting mechanism and the support platform are misaligned in the first direction, it can promptly prompt the operator to adjust the position of the support platform or the fixed bracket to align them, thereby improving the efficiency of panel handling and saving manpower.

[0049] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
