Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and in particular to a floating docking device and docking pallet system that is capable of floating and accommodating manufacturing and assembly errors between different pallets and different ground fixtures, and is suitable for AGV conveying and transfer in automated workshops. Background Technology

[0002] AGVs are used to transport pyrotechnics, explosives, and pyrotechnic agents. The equipment used in conjunction with AGVs includes docking pallet fixtures and ground mounting frames. Automated workshops require a large number of pallets and ground mounting frames distributed across different workstations.

[0003] However, these pallets and ground fixtures are manufactured through welding, and there are significant manufacturing and assembly errors between different pallets and ground fixtures, resulting in situations where pallets and fixtures cannot be properly aligned. Secondly, during the transport of pyrotechnics, explosives, and pyrotechnic agents by the AGV, pneumatic clamps are required on the pallets to clamp the materials. After being transported to the workstation, the clamps are released to ensure the safety of the transport process.

[0004] In existing AGV automated transfer processes, due to processing and assembly errors, different pallets may fail to connect with different ground mounting frames. Additionally, there are issues such as the inconvenience of installing pneumatic clamps on the pallets due to limited air supply.

[0005] It is evident that the current manufacturing processes for pyrotechnics, explosives, and pyrotechnic agents suffer from problems such as high labor intensity during manual handling, large manufacturing errors and poor interchangeability of docking pallet tooling, and difficulty in connecting gas lines. Summary of the Invention

[0006] In view of the above problems, the present invention provides a floating docking device and docking tray system for overcoming or at least partially solving the above problems.

[0007] This invention provides the following solution:

[0008] A floating docking device, comprising:

[0009] The first floating assembly includes a first mounting block, a sliding sleeve, a centering clamping mechanism, and a first air passage docking mechanism.

When the sliding sleeve floats in any direction, it drives the corresponding rocker to swing, and simultaneously, the rotating block drives the rotating ring to rotate, causing the three rockers to swing synchronously. After the docking plug and the docking slot are docked, the rockers swing towards the center under the action of the compression spring.

After disengagement, the docking mechanism can maintain pressure in the tray's internal air passages. A centering and clamping mechanism can return the floating sliding sleeve to its initial position. It can be used in conjunction with AGV trolleys to achieve automated transfer of pyrotechnics, explosives, and pyrotechnic agents, avoiding human intervention during material transfer and achieving human-machine isolation.

Detailed Implementation

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0044] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 This is a dynamic docking device provided in an embodiment of the present invention, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, the device may include:

[0045] The first floating component 1 includes a first mounting block 11, a sliding sleeve 12, a centering clamping mechanism 13, and a first air passage docking mechanism. The sliding sleeve 12 has a first annular groove in which a ring of balls 14 are arranged. The sliding sleeve 12 and the balls 14 are confined by the centering clamping mechanism 13 within the cylindrical inner cavity of the first mounting block 11. The inner cavity size is larger than the corresponding step size of the sliding sleeve 12. The first air passage docking mechanism is connected to the sliding sleeve 12. The bottom of the sliding sleeve 12 is open, forming a docking slot.

[0046] The second floating component 2 includes a second mounting block 21 and a second air passage docking mechanism; the second air passage docking mechanism is connected to the second mounting block 21; the second mounting block 21 is provided with a docking plug adapted to the docking slot, the docking plug including a front tapered part and a columnar part;

[0047] During the docking process between the plug and the slot, the tapered front end contacts the inner wall of the slot, and the sliding sleeve 12 can slide in the inner cavity to float in two directions on the plane, so that the columnar part can enter the slot to complete the docking; the centering clamping mechanism 13 is used to reset the sliding sleeve 12 to the center position after the docking plug and the slot are docked, thereby achieving the reset and centering of the sliding sleeve 12;

[0048] The first air path docking mechanism and the second air path docking mechanism achieve air path connection after the docking slot and the docking plug are docked.

[0049] The floating docking device provided in this application embodiment can float in three vertical directions and simultaneously in two planar directions. Even when there are manufacturing errors in the equipment used in the first floating component 1 and the second floating component 2, successful docking can still be achieved, eliminating the docking impact caused by manufacturing and assembly errors. Furthermore, after docking, the first air path docking mechanism included in the first floating component 1 and the second air path docking mechanism included in the second floating component 2 can be connected, thereby achieving unobstructed airflow. This airflow can provide an air source interface for the starting device used on the first floating component 1. After the first floating component 1 and the second floating component 2 separate, the first air path docking mechanism will also separate from the second air path docking mechanism, without affecting the normal transport of components that need to be moved and installed on the first floating component 1.

[0050] The centering clamping mechanism 13 provided in this application embodiment can achieve floating in two directions on the plane without affecting the sliding sleeve 12's ability to slide within the inner cavity, while also resetting the sliding sleeve 12 to the center position after docking, thus achieving centering and resetting of the sliding sleeve 12. To this end, this application embodiment can provide the centering clamping mechanism 13 including a rotating ring 131, rollers 132, three rockers 133, a compression spring 134, three rotating blocks 135, three cantilever pins 136, a third mounting block 137, and a pressure plate 138. The rotating ring 131 has a second annular groove, inside which a ring of balls 14 are fitted, and the pressure plate 138 restricts them within the third mounting block 137. The three rotating blocks 135 are evenly distributed on the rotating ring 131, and each rotating block 135 can rotate around its own axis. The three rockers 133 pass through the three rotating blocks 135 one-to-one and can slide within the corresponding rotating blocks 135. The other end of rod 133 is fixed to one of the three cantilever pins 136; under the action of compression spring 134, roller 132 is pressed against sliding sleeve 12; when sliding sleeve 12 floats in any direction, it drives the corresponding rocker arm 133 to swing, and at the same time, under the action of rotating block 135, it drives rotating ring 131 to rotate, so that the three rocker arms 133 swing synchronously; after the docking plug and docking slot are docked, the rocker arm 133 swings towards the center under the action of compression spring 134, and the three rocker arms 133 swing synchronously through rotating ring 131, so that sliding sleeve 12 is reset to the center position, realizing the reset and centering of sliding sleeve 12.

[0051] Furthermore, embodiments of this application may also provide the first gas path docking mechanism including a first pipe connector 15, a sealing shell 16, a first retaining ring 17, a first retaining ring 18, a first spring 19, a piston 110, a piston sleeve 111, and a first sealing ring 112;

[0052] The piston sleeve 111 and the sealing shell 16 are both fixedly connected to the sliding sleeve 12. The piston sleeve 111 is located inside the sealing shell 16 and forms an airflow gap with the sealing shell 16. The first pipe joint 15 is fixedly connected to the sealing shell 16. The top of the piston sleeve 111 is provided with an inlet and outlet. The piston 110 is confined within the piston sleeve 111 by the first retaining ring 17, the first retaining ring 18, and the first spring 19. The side of the piston sleeve 111 is provided with a plurality of first vent holes. In the initial state of the first spring 19, the piston 110 is used to block the plurality of first vent holes. In the compressed state of the first spring 19, the plurality of first vent holes, the airflow gap, and the first pipe joint 15 form an airflow channel.

[0053] When the first floating component 1 is used in combination with the tray, the first pipe connector 15 can be connected to the pneumatic clamp on the tray to provide the airflow required to drive the pneumatic clamp. In addition, when the first air path docking mechanism is separated from the second air path docking mechanism, the first spring 19 will drive the piston 110 to move down to the initial position. The piston 110 can block several first vent holes to achieve the purpose of maintaining air pressure.

[0054] Furthermore, embodiments of this application may also provide a second gas path docking mechanism including a second sealing ring 22, a second retaining ring 23, a second retaining ring 24, a sliding vent pin 25, a second pipe connector 26, a sealing ring mounting ring 27, a second spring 28, a third retaining ring 29, and a third retaining ring 210;

[0055] The sliding vent pin 25 is confined within the inner cavity of the second mounting block 21 by the second sealing ring 22, the second retaining ring 23, the second retaining ring 24, the sealing ring mounting ring 27, the second spring 28, the third retaining ring 29, and the third retaining ring 210, and can slide up and down along the inner cavity; the interior of the sliding vent pin 25 forms a cavity structure, the second pipe connector 26 is connected to the lower end of the sliding vent pin 25, and the upper end of the sliding vent pin 25 is provided with a plurality of second vent holes; after the docking plug is docked with the docking slot, the first vent hole and the second vent hole are opposite to and connected.

[0056] The second sealing ring 22 includes a Y-shaped sealing ring.

[0057] To eliminate the problem of gaps between the lower mounting block and piston sleeve 111 affecting the sealing performance due to manufacturing and assembly errors causing the first floating upper component and the second floating lower component to be at different heights, this embodiment of the application can also provide that the stiffness coefficient of the second spring 28 is greater than that of the first spring 19. At this time, the sliding vent pin 25 lifts the piston 110, and the compression of the second spring 28 decreases, thereby achieving floating in the docking (vertical) direction.

[0058] It is understood that the floating docking device provided in this application embodiment can be applied to various application scenarios that require temporary docking of two components. For example, in one implementation, such as Figure 11 , Figure 12 , Figure 13 , Figure 14 As shown, this application embodiment can provide a docking pallet system, including a ground fixing frame 4 and a pallet body 3. The ground fixing frame 4 is provided with a plurality of the above-mentioned second floating components 2, and the pallet body 3 is provided with a plurality of the above-mentioned first floating components 1.

[0059] The pallet body and the ground fixing frame 4 achieve structural floating docking and air circuit docking through a number of first floating components 1 and a number of second floating components 2.

[0060] Specifically, the tray body includes a welded rectangular tube frame and a rectangular panel; a plurality of the first floating components 1 are disposed at the four corners of the rectangular panel.

[0061] The ground-fixed frame 4 includes a welded frame and feet. The welded frame includes four support columns, and several second floating components 2 are correspondingly arranged on the top of the four support columns. The bottom of the ground-fixed frame allows the AGV trolley 5 to enter and exit.

[0062] The following section takes the use of the floating docking device provided in the embodiments of this application in a pallet system as an example to provide a detailed description of the structure and usage of the floating docking device provided in the embodiments of this application.

[0063] The pallet system includes a pallet, a floating docking device, and a ground fixing frame 4. The floating docking device includes a first floating component 1 and a second floating component 2.

[0064] The pallet is constructed from a welded rectangular tube frame and a welded panel. The ground mounting frame 4 consists of a welded frame and feet. The ground mounting frame 4 is fixed to the ground with screws. The pallet is transported by an AGV. When the pallet is transported to the ground mounting frame 4, the AGV places the pallet on the ground mounting frame 4. The first floating component 1 and the second floating component 2 of the floating docking device then perform floating docking and complete the air circuit docking.

[0065] The floating docking device mainly includes: a first floating component 1 and a second floating component 2.

[0066] like Figure 2 , Figure 3 As shown, the first floating component 1 includes: a first pipe joint 15, a sealing shell 16, a first mounting block 11, a ball 14, a first retaining ring 17, a first retaining ring 18, a first spring 19, a piston 110, a piston sleeve 111, a first sealing ring 112, a centering clamping mechanism 13, and a sliding sleeve 12.

[0067] The sliding sleeve 12 has an annular groove in which a ring of balls 14 are arranged. The sliding sleeve 12 and the balls 14 are constrained within the cylindrical cavity of the first mounting block 11 by a centering clamping mechanism 13. The cavity size is larger than the corresponding step size of the sliding sleeve 12, thus allowing the sliding sleeve 12 to slide within the cavity and float in two directions on the plane. The first air passage connection mechanism is mainly composed of a first pipe connector 15, a sealing shell 16, a first retaining ring 17, a first retaining ring 18, a first spring 19, a piston 110, a piston sleeve 111, and several first sealing rings 112. This part is all mounted on the sliding sleeve 12 and floats with it. The piston 110 can move up and down within the piston sleeve 111 and is reset by the first spring 19. Piston sleeve 111 has a through hole on the cylindrical surface of the piston 110 in the middle. When piston 110 moves upward a certain distance, the air chamber formed by first pipe joint 15 and sealing shell 16 forms a communication air passage with piston sleeve 111 through the annular hole. When piston 110 moves downward, it is pushed and pressed against piston sleeve 111 by first spring 19, and the air passage is sealed by first sealing ring 112, thus maintaining air pressure in the air chamber formed by first pipe joint 15 and sealing shell 16.

[0068] like Figure 7 , Figure 8 As shown, the second floating assembly 2 includes: a Y-shaped second sealing ring 22, a second retaining ring 23, a second retaining ring 24, a sliding vent pin 25, a second mounting block 21, a second pipe connector 26, a sealing ring mounting ring 27, a second spring 28, a third retaining ring 29, and a third retaining ring 210. The sliding vent pin 25 can slide up and down within the second mounting block 21 and is reset by the second spring 28. The Y-shaped second sealing ring 22, the second retaining ring 23, the second retaining ring 24, and the sealing ring mounting ring 27 are mounted on the upper part of the second mounting block 21 to achieve dynamic sealing of the sliding inner cavity.

[0069] During docking, the first floating component 1 docks downwards with the second floating component 2. First, the sliding sleeve 12 docks with the second mounting block 21 and floats according to the position of the second mounting block 21. The stiffness coefficient of the second spring 28 is greater than that of the first spring 19. The sliding vent pin 25 is inserted into the piston sleeve 111, first lifting the piston 110. After the piston 110 stops against the first retaining ring 18, the second spring 28 is compressed, and the sliding vent pin 25 moves downwards, achieving docking. Figure 9 , Figure 10 As shown.

[0070] When a first floating component 1 and a second floating component 2 in the device are not at the same height position due to manufacturing and assembly errors, a gap will appear between the second mounting block 21 and the piston sleeve 111. At this time, the sliding vent pin 25 will lift the piston 110, and the compression of the second spring 28 will decrease, thereby achieving floating in the docking (vertical) direction.

[0071] After docking, the second pipe connector 26, the sliding vent pin 25, the cylindrical through hole of the piston sleeve 111, the sealing shell 16, and the first pipe connector 15 form a connected air passage, and the air source provides air to the tray from bottom to top.

[0072] When disengaged, piston 110 moves downward and is pressed against piston sleeve 111 by first spring 19, and the air passage is sealed by first sealing ring 112, and the air passage pressure is maintained in the air chamber formed by first pipe joint 15 and sealing shell 16.

[0073] like Figure 4 , Figure 5 , Figure 6 As shown, the centering clamping mechanism 13 consists of a rotating ring 131, rollers 132, rocker arms 133, compression springs 134, rotating blocks 135, cantilever pins 136, a third mounting block 137, and a pressure plate 138. The rotating ring 131 has an annular groove and is fitted with a ring of ball bearings 14. It is confined within the third mounting block 137 by the pressure plate 138, allowing it to rotate. The rotating blocks 135 are evenly distributed on the rotating ring 131 and can rotate around their own axis. The rocker arm 133 passes through the rotating block 135 and can slide within it. The other end of the rocker arm 133 is fixed to the cantilever pin 136. Under the action of the compression spring 134, the rollers 132 are pressed against the sliding sleeve 12. When the sliding sleeve 12 floats in a certain direction, it causes the rocker arm 133 to swing. Simultaneously, the rotating blocks 135 drive the rotating ring 131 to rotate, causing the three rocker arms 133 to swing synchronously. When the docking is completed, the rocker arm 133 swings toward the center under the action of the compression spring 134. The three rocker arms 133 swing synchronously through the rotating ring 131, and the sliding sleeve 12 is reset to the center position, thus realizing the reset and centering of the sliding sleeve 12.

[0074] After the pallet is docked and positioned with the ground fixing frame 4, air can be vented through the air passage inside the pallet. After disengagement, the docking mechanism can maintain pressure in the air passage inside the pallet. The centering clamping mechanism 13 can return the floating sliding sleeve 12 to its initial position.

[0075] In summary, the floating docking device provided in this application can float in three vertical directions, enabling docking between different pallets and different bases, eliminating the impact of manufacturing and assembly errors on docking. After the pallet is docked and positioned with the ground fixing frame, air can be vented through the air passages inside the pallet. After disengagement, the docking mechanism can maintain pressure in the air passages inside the pallet. The centering and clamping mechanism can return the floating sliding sleeve to its initial position. It can be used in conjunction with AGV trolleys to achieve automated transfer of pyrotechnics, explosives, and pyrotechnic agents, avoiding human intervention during material transfer and achieving human-machine isolation.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

The second floating component includes a second mounting block and a second air passage docking mechanism; the second air passage docking mechanism is connected to the second mounting block; the second mounting block is provided with a docking plug adapted to the docking slot, the docking plug including a front tapered portion and a columnar portion; During the docking process between the plug and the slot, the tapered front end contacts the inner wall of the slot, and the sliding sleeve can slide in the inner cavity to float in two directions on the plane, so that the columnar part can enter the slot to complete the docking; the centering clamping mechanism is used to reset the sliding sleeve to the center position after the docking plug and the slot are docked, thereby achieving the reset and centering of the sliding sleeve. After the first air path docking mechanism and the second air path docking mechanism are docked with the docking slot and the docking plug, the air path is connected. The centering clamping mechanism includes a rotating ring, rollers, three rockers, a compression spring, three rotating blocks, three cantilever pins, a third mounting block, and a pressure plate. The rotating ring has a second annular groove, inside which a ring of balls is fitted and confined within the third mounting block by the pressure plate. The three rotating blocks are evenly distributed on the rotating ring and can rotate around their own axes. The three rockers pass through the three rotating blocks one by one and can slide within their respective rotating blocks. The other ends of the three rockers are fixed to the three cantilever pins one by one. Under the action of the compression spring, the rollers are pressed against the sliding sleeve. When the sliding sleeve floats in any direction, it drives the corresponding rocker to swing, and simultaneously, the rotating blocks drive the rotating ring to rotate, causing the three rockers to swing synchronously. After the docking plug and the docking slot are docked, the rockers swing towards the center under the action of the compression spring. The rotating ring synchronizes the swing of the three rockers, resetting the sliding sleeve to the center position, thus achieving centering and resetting the sliding sleeve.
