Description

Technical Field

[0001] This application relates to the field of conveying machinery, and in particular to a mechanical blocking mechanism. Background Technology

[0002] AGVs, also known as automated guided vehicles, are unmanned intelligent material handling equipment. Due to their high flexibility and safety, they are now widely used in industries such as manufacturing, logistics and warehousing, medical care, and food.

[0003] In related technologies, when using an AGV (Automated Guided Vehicle) to move a workpiece from one stage to the next, the AGV is typically moved to the output side of the previous stage, and the workpiece is conveyed from the previous stage to the top of the AGV via a conveyor belt. Then, the AGV is moved to the input side of the next stage, and the workpiece is conveyed from the top of the AGV to the next stage via a conveyor belt. The top of the AGV is equipped with baffles for the workpiece to abut at both ends, and a controller is installed to control the opening and closing of the baffles. The baffles have interlocked and unlocked positions. When the workpiece is positioned on top of the AGV, the baffles are in the interlocked position; when the workpiece is not on top of the AGV, the baffles are in the unlocked state. Because the baffles are driven by electronic control, system malfunctions or electromagnetic interference can easily cause the baffles to lose their blocking effect.

[0004] In view of the aforementioned technologies, the inventors believe that there is a need to provide a blocking mechanism with relatively ideal reliability. Utility Model Content

[0005] In order to improve the problem of the blocking effect failing due to system failure or electromagnetic interference, this application provides a mechanical blocking mechanism.

[0006] The mechanical blocking mechanism provided in this application adopts the following technical solution:

[0007] A mechanical blocking mechanism includes a first blocking assembly mounted on an AGV (Automated Guided Vehicle) trolley, a second blocking assembly mounted on a platform, a first guide mounted on the AGV trolley, and a second guide mounted on the platform. The first blocking assembly includes a first blocking seat and a first blocking member rotatably mounted on the first blocking seat. The first blocking member has a first blocking plate and a first trigger mounted on the first blocking plate. The second blocking assembly includes a second blocking seat and a second blocking member rotatably mounted on the second blocking seat. The second blocking member has a second blocking plate and a second trigger mounted on the second blocking plate. The first guide is mounted on one side of the first blocking assembly along the AGV trolley's moving direction and is used to abut against the second trigger and drive the second blocking member to flip. The second guide is mounted on one end of the second blocking assembly away from the AGV trolley's moving direction, and the second guide has a guide surface structure for the first trigger to abut against and drive the first blocking plate to flip.

[0008] By adopting the above technical solution, when the AGV moves to the side of the platform, the first trigger of the first blocking component on the AGV abuts against the guide surface structure of the second guide, causing the first blocking plate to flip; at the same time, the second trigger of the second blocking component on the platform abuts against the first guide, causing the second blocking plate to flip. The workpiece is transported from the AGV to the platform by the conveyor belt, thus realizing the connection function when the AGV docks with the platform; after the workpiece is transported, the AGV continues to move, and the first blocking component separates from the second guide, and the second blocking component separates from the first guide, causing the first blocking plate and the second blocking plate to reset, realizing the blocking function after the AGV docks with the platform, which helps to improve the problem of blocking effect failure caused by system failure or electromagnetic interference.

[0009] Optionally, the first trigger includes a first column arranged perpendicular to the AGV's moving direction and a first trigger wheel rotatably mounted on the end of the first column.

[0010] By adopting the above technical solution, the specific structure of the first trigger element is disclosed. The setting of the first trigger wheel helps to reduce the wear when the first trigger element contacts the second guide element, thereby helping to improve the service life of the first trigger element and the second guide element.

[0011] Optionally, the guide surface structure includes a first guide surface and a first horizontal surface along the moving direction of the AGV, wherein the first horizontal surface is connected to the highest point of the first guide surface.

[0012] By adopting the above technical solution, when the first triggering element abuts against the guide surface structure, the first guide surface can guide the first triggering element to move smoothly and make the first blocking plate flip smoothly; the setting of the first horizontal surface provides stable support for the first triggering element, so that the first blocking plate is not easy to swing back and forth after it is flipped into place, which helps to ensure the stability of the mechanical blocking mechanism.

[0013] Optionally, the guide surface structure further includes a second guide surface connected to the first horizontal plane, wherein the first horizontal plane is connected to the highest point of the second guide surface.

[0014] By adopting the above technical solution, the setting of the second guide surface helps to further optimize the flipping process of the first blocking plate, making the transition between blocking and unlocking actions between the AGV and the platform smoother.

[0015] Optionally, the second blocking member further includes a second rotating shaft connecting the second blocking plate and the second trigger member; the second trigger member includes a connecting rod vertically connected to the second rotating shaft and a second abutting portion connected to the end of the connecting rod and used for abutting by the first guide member; the second abutting portion has a second abutting surface for abutting by the first guide member.

[0016] By adopting the above technical solution, the specific structure of the second trigger is disclosed. The second trigger is connected to the second blocking plate and the second trigger by the second rotating shaft, and is vertically connected to the second rotating shaft and the second abutment by the connecting rod, so as to realize that the rotation of the second trigger drives the second blocking plate to rotate coaxially. The setting of the second abutment surface helps the first guide to effectively drive the second blocking member to flip, thereby realizing the blocking and unlocking functions of the mechanical blocking mechanism.

[0017] Optionally, the first guide includes a mounting base installed on the AGV trolley, a second column vertically connected to the mounting base, and a first guide wheel rotatably mounted on the second column and used to abut against the second abutment surface.

[0018] By adopting the above technical solution, the specific structure of the first guide member is disclosed. The first guide wheel, which is rotatably installed, can flexibly abut against the second abutment surface, which helps to drive the second blocking member to flip and realize the action switching of the blocking mechanism.

[0019] Optionally, the first blocking assembly further includes a first buffer block installed on the AGV trolley and used for resetting and abutting against the first blocking plate.

[0020] By adopting the above technical solution, the setting of the first buffer block can make the first abutment plate reset smoothly, which helps to reduce the risk of damage to the components due to large impact between the first buffer plate and the AGV trolley during reset, thereby helping to improve the stability and service life of the first blocking component.

[0021] Optionally, the second blocking assembly further includes a second buffer block mounted on the platform and used for resetting and abutting against the second blocking plate.

[0022] By adopting the above technical solution, the setting of the second buffer block can make the second blocking plate reset smoothly, which helps to reduce the risk of damage to the components due to large impact between the plate and the platform during reset, thereby helping to improve the stability and service life of the second blocking assembly.

[0023] Optionally, the top of the first blocking plate is provided with a first inclined surface, which is in a horizontal state when the first blocking component is in the unlocked state.

[0024] By adopting the above technical solution, a first inclined surface is set at the top of the first blocking plate and the first inclined surface is in a horizontal state when the first blocking component is in the unlocked state, so that the AGV trolley and the platform can be successfully docked and the workpiece can be transported in a directional manner, which helps to ensure the smooth operation of the equipment.

[0025] Optionally, the top of the second blocking plate is provided with a second inclined surface, which is in a horizontal state when the second blocking component is in the unlocked state.

[0026] By adopting the above technical solution, a second inclined surface is set at the top of the second blocking plate and the second inclined surface is in a horizontal state when the second blocking component is in the unlocked state, so that the AGV trolley and the platform can be successfully docked and the workpiece can be transported in a directional manner, which helps to further ensure the smooth operation of the equipment.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0045] The implementation principle of a mechanical blocking mechanism in this application embodiment is as follows: When the AGV trolley 7 moves to the side of the platform 8, the first trigger 123 of the first blocking component 1 located on the AGV trolley 7 abuts against the guide surface structure of the second guide 4, causing the first blocking plate 122 to flip. At the same time, the second trigger 322 of the second blocking component 3 located on the platform 8 abuts against the first guide 2, causing the second blocking plate 323 to flip. The first blocking component 1 and the second blocking component 3 enter the unlocked state. At this time, the first inclined surface 1221 and the second inclined surface 3231 are both in a horizontal state. The first infrared switch 52 and the second infrared switch 62 respectively transmit signals. The workpiece is transferred to the conveying mechanisms located on both sides. The workpiece is then transported from the AGV trolley 7 to the platform 8 via the conveying mechanisms, thus realizing the connection function when the AGV trolley 7 docks with the platform 8. After the workpiece is transported, the AGV trolley 7 continues to move. The first blocking component 1 and the second guide component 4, and the second blocking component 3 and the first guide component 2 are all separated, so that the first blocking plate 122 and the second blocking plate 323 are reset. The first blocking component 1 and the second blocking component 3 enter an interlocked state, realizing the blocking function after the AGV trolley 7 docks with the platform 8. This helps to improve the problem of the blocking effect failing due to system failure or electromagnetic interference.

[0046] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
