Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to a highly reliable fully automatic switch and latch device. Background Technology

[0002] Currently, all military storage boxes have latches on their lids, which are typically opened and closed manually. This is dangerous for workers operating these latches in the military production area. Compared to traditional manual methods, automating the opening and closing of latches results in inconsistent operation of military storage boxes. While manual methods can quickly learn and adapt to different latch opening and closing mechanisms, machines face difficulties in adapting, potentially leading to a low degree of automation in the opening and closing process. Therefore, there is an urgent need for a highly reliable, fully automatic latch opening and closing device to replace manual labor and make production safer. Summary of the Invention

Detailed Implementation

[0035] To facilitate understanding of the present invention, a more comprehensive description will be given below with reference to the accompanying drawings. Two embodiments of the invention are shown in the drawings. However, the present invention can be implemented with many different types of enclosures and is not limited to the embodiments described herein. Rather, these embodiments serve to provide a more comprehensive and thorough explanation of the invention.

[0036] It should be noted that when a part is described using the terms "installation" or "connection," it means that the part is attached to another part, and other parts or intermediate parts can also be used to fix the two parts together. The fixing method is a connection through bolts and mounting plates, but it is not limited to this method.

[0037] like Figure 1 As shown, this invention provides a highly reliable fully automatic lock and latch device, including a three-axis palletizer and a robot 60 connected to the three-axis palletizer. The three-axis palletizer provides three-dimensional motion for the robot 60, which is used to automatically open and close the box lock and latch. The three-axis palletizer includes a three-axis palletizer support 50 and X-axis linear motion modules, Y-axis linear motion modules, and Z-axis linear motion modules arranged on the support 50 and connected sequentially from bottom to top. The output end of the Z-axis linear motion module is connected to the robot 60 via a robot mounting connector 70. The three-axis palletizer realizes three degrees of freedom for the robot 60 to move along the X-axis guide rail 20, the Y-axis guide rail 30, and the Z-axis guide rail 40.

[0038] During operation, the container is moved to the underside of the three-axis palletizer support 50 via a conveyor. The palletizer controls the orientation of the robotic arm 60, moving it along the X, Y, and Z three-dimensional directions. The top of the robotic arm 60 is connected to the robotic arm mounting connection 70 via an air valve. Disconnecting the air valve allows for quick replacement of the robotic arm 60, or minor adjustments to the robotic arm 60 can achieve versatility for most containers.

[0039] like Figure 2 As shown, in one embodiment of the present invention, the robotic arm 60 includes a rotary robotic arm base 1, a hook 2, a box cover assembly 3, a rotary robotic arm assembly 4, and a locking buckle assembly 5. The top of the rotary robotic arm base 1 is provided with a robotic arm replacement connection 6, which is connected to a robotic arm mounting connection 70 of a three-axis palletizer. The hook 2 is located on one side of the rotary robotic arm base 1 and is used to grip the box cover. The three-axis palletizer moves the hook 2 to open or close the box cover. The rotary robotic arm assembly 4 and the locking buckle assembly 5 are located on the other side of the rotary robotic arm base 1, with the locking buckle assembly 5 positioned above the rotary robotic arm assembly 4. The rotary robotic arm assembly 4 is used to operate the locking lever, and the locking buckle assembly 5 is used to tighten the locking buckle. The box cover assembly 3 is located on the top of the rotary robotic arm base 1 and is used to tighten the box cover.

[0040] like Figure 3 As shown, in an embodiment of the present invention, the hook 2 includes a hook base 201 and a box cover clamping structure 202. The hook base 201 is connected to the rotary robotic arm base 1. Hook rubber blocks are provided at both ends of the bottom of the hook base 201, and the two hook rubber blocks form the box cover clamping structure 202.

[0041] like Figure 4 As shown, in an embodiment of the present invention, the pressure box cover assembly 3 includes a pressure box cover assembly connecting part I 301, a telescopic push rod 302, and a nylon pressure block 303. The pressure box cover assembly connecting part I 301 is connected to the top of the rotary robotic arm base 1. The telescopic push rod 302 is vertically arranged below the pressure box cover assembly connecting part I 301, and the output end of the telescopic push rod 302 is connected to the nylon pressure block 303.

[0042] like Figure 5 As shown, in an embodiment of the present invention, the rotary robotic arm assembly 4 includes a rotary cylinder, a rotary cylinder connecting pair 401, a rotary robotic arm side arm 402, a robotic finger 403, a rotary robotic arm base 404, and a spring assembly I 405. The rotary robotic arm base 404 has rotary robotic arm side arms 402 at both ends, and each rotary robotic arm side arm 402 has a rotary cylinder connecting pair 401. The two rotary cylinder connecting pairs 401 are respectively connected to two rotary cylinders mounted on the rotary robotic arm base 1. The rotary robotic arm base 404 is connected to two robotic fingers 403 via two spring assemblies I 405. The spring assemblies I 405 control the contact force of the robotic fingers 403 during the contact process, ensuring the safety and reliability of the equipment.

[0043] like Figure 6 As shown in the embodiment of the present invention, the pressure-locking assembly 5 includes a cylinder connecting pair 501, a cylinder 502, a spring assembly II 503, a fixed baffle 504, a Z-shaped bracket 505, and a nylon push rod 506. The cylinder 502 is connected to the rotary robotic arm base 1 via the cylinder connecting pair 501. One end of the cylinder connecting pair 501 is connected to the fixed baffle 504, and the output end of the cylinder 502 is connected to the Z-shaped bracket 505. The Z-shaped bracket 505 is connected to the fixed baffle 504 via the spring assembly II 503. The nylon push rod 506 is connected to the Z-shaped bracket 505. The contact force during the contact process of the nylon push rod 506 is controlled by the spring assembly II 503 to ensure the safety and reliability of the equipment.

[0044] like Figure 7As shown, the robotic arm 60 provided in this embodiment is used for the locking switch of the box I 80. A box cover 81 is hinged to the top of the box I 80. The box I 80 is a single-sided lock. A locking hook 82 is provided on the box cover 81. A locking lever 84 is hinged to the upper part of the box I 80, and a locking latch 83 is hinged to the outer side of the locking lever 84. By turning the locking lever 84, the locking latch 83 rotates upward, causing the upper end of the locking latch 83 to fall into the groove of the locking hook 82, thus achieving the locking action. The automatic locking process of the robotic arm 60 is as follows:

[0045] Box 80 is mounted on a box support, with the box cover 81 in the open position. The three-axis palletizer moves the mobile robot 60 to the correct position above the box cover. The robot 60 moves downward, and the box cover 81 falls into the box cover clamping structure 202. The three-axis palletizer moves the robot 60 along the X-axis direction along the guide rail 20 in the positive X-axis direction, and the box cover gradually falls and eventually closes under the action of gravity.

[0046] After the robotic arm 60 moves, it stops moving when the pressure box cover assembly 3 is in the correct position. At this time, the robotic finger 403 on the rotary robotic arm assembly 4 is exactly in the gap between the locking wrench 84 and the box body I 80. Simultaneously, the robotic arm 60 moves 5cm along the positive Z-axis of the three-axis palletizer. Since the robotic finger 403 cannot move while in the locking wrench 84, the spring assembly I 405 below the robotic finger 403 will be compressed. The purpose is that when the locking wrench 83 rotates along the axis of the rotary cylinder connecting pair 401, the spring assembly I 405 will always provide outward support force to the robotic finger 403, keeping the robotic finger 403 extended outward and preventing relative displacement during rotation from causing the robotic finger 403 to fall out of the locking wrench 84, thus causing machine malfunction. Figure 8 As shown. Then, the rotary robotic arm assembly 4 rotates 125° counterclockwise along the rotation axis of the rotary cylinder connecting pair 401. The axis of the locking latch 83 and the axis of the rotary cylinder connecting pair 401 are coaxial, and the locking lever 84 is opened, as shown. Figure 9 As shown. Normally, the upper end of the latch 83 would fall close to the side of the housing I 80 due to gravity. However, to ensure reliability, the latch assembly 5 of this device moves towards the housing I 80, and the nylon push rod 506 presses the latch 83 tightly against the housing I 80. Simultaneously, the spring assembly II 503 applies a pushing force to the nylon push rod 506. Figure 6 , Figure 10 As shown.

[0047] At this time, the robotic arm 60 will move a certain distance away from the latch 83. The relative position of the latch assembly 5 and the latch 83 in the Z-axis direction will retain a certain amount of redundancy. This is to prevent the latch assembly 5 from dislodging the upper end of the latch 83 during the movement of the robotic arm 60 away from the latch 83. Simultaneously, the robotic finger 403 on the rotary robotic arm assembly 4 will be removed from the latch lever 84, and the latch lever 84 will automatically fall under the influence of gravity. Figure 11 As shown. To ensure reliability, the robotic arm 60 will move to the upper surface of the locking lever 84, then rotate 125° clockwise to pull the locking lever 84 downwards, completing the locking action. At this point, the cover-closing and locking actions are complete, and the robotic arm 60 is initialized to its position, as shown. Figure 12 As shown.

[0048] like Figure 13 As shown, in another embodiment of the present invention, the robotic arm 60 includes a rotary robotic arm support 10, a box cover assembly 3, a rotary robotic arm assembly 4, and a locking buckle assembly 5. The box cover assembly 3 is disposed on the top of the rotary robotic arm support 10 and is used to press the box body. Two rotary robotic arm assemblies 4 are symmetrically arranged on both sides of the rotary robotic arm support 10. Each rotary robotic arm assembly 4 is provided with a locking buckle assembly 5 above it. The locking buckle assembly 5 presses the box body lock buckle so that the lock buckle is always connected to the lock hook when the rotary robotic arm 4 turns the lock buckle wrench, preventing the lock buckle from disengaging from the lock hook on the box cover when the rotary robotic arm 4 turns the lock buckle wrench, which would cause the locking to fail. The rotary robotic arm assembly 4 is used to turn the box body lock buckle wrench.

[0049] like Figure 14 As shown, in an embodiment of the present invention, the rotary robotic arm support 10 includes a support connecting pair 101, a gripper base 102, a rotary robotic arm mounting frame 103, and a rotary cylinder 105. The gripper base 102 is connected to a three-axis palletizer via the support connecting pair 101. Two rotary robotic arm mounting frames 103 are connected to each side of the gripper base 102, and two rotary robotic arm mounting frames 103 are connected to each side of the other two rotary cylinders 105. The rotary robotic arm assembly 4 is installed between the two rotary cylinders 105. A locking assembly connecting pair 106 is provided in the middle of each rotary robotic arm mounting frame 103 for installing the locking assembly 5.

[0050] like Figure 15As shown in the embodiment of the present invention, the gripper base 102 includes a Y-axis guide rail 1022, a gear 1023, a slide 1024, a gear set mounting plate 1025, a driven gear 1026, a rack 1028, and a power cylinder. The gear set mounting plate 1025 is connected to the support connecting pair 101. The gear 1023 and two driven gears 1026 are rotatably mounted on the gear set mounting plate 1025, and the two driven gears 1026 mesh with the gear 1023. The two Y-axis guide rails 1022 are connected to the support connecting pair 101, and the Y-axis guide rails 1022 are connected to the two slides 1024. 4. Sliding connection: Two racks 1028 parallel to the Y-axis guide rail 1022 are respectively provided on the two slides 1024. The two racks 1028 are arranged opposite each other and mesh with two driven gears 1026 respectively. The power cylinder is set on the support connecting pair 101, and the output ends on both sides are connected to the two slides 1024 respectively. The power cylinder is used to drive the two slides 1024 to move closer or further away from each other. The gear set formed by the two driven gears 1026 and gear 1023 ensures the synchronicity of the two slides when they move closer or further away. The two slides 1024 are respectively connected to two rotary robotic arm mounting frames 103.

[0051] Furthermore, limit blocks 1021 are installed at the ends of the two Y-axis guide rails 1022 to limit the movement of the two slides 1024.

[0052] In this embodiment, the locking assembly 5 is simplified compared to one embodiment of the present invention, consisting of a push cylinder and a pressure plate. The push cylinder is fixed to the locking assembly connecting part 106 near the rotary robotic arm assembly 4 via a V-shaped mounting connector, and is located on the outside of the rotary robotic arm support 10. The fixing and connection methods at both ends are the same. When the lock is opened, the extension rod of the push cylinder extends, the pressure plate approaches the lock and presses it against the housing. After the lock's degree of freedom is restricted, the rotary robotic arm assembly 4 begins to pull the lock lever to complete the locking and unlocking action.

[0053] It should be added that the pressure box cover assembly 3 and the rotary robotic arm assembly 4 in another embodiment have the same composition and working principle as those in the first embodiment, so they will not be described again in this embodiment.

[0054] like Figure 16 As shown, the robotic arm 60 provided in this embodiment is used to open and close the latches of the box II 90. The box II 90 has symmetrical latches on both sides of the lid, and the opening and closing method is double-sided unlocking. The specific opening and closing process is as follows:

[0055] During operation, housing II 90 is fixed to the housing support. The robotic arm 60 moves above housing II 90 and, once in the correct position, begins to fall. After falling, the power cylinder below the support connecting pair 101 shortens, causing the two slides 1024 to move closer together. The rack 1028 above the two slides 1024 drives the driven gear 1026. Under the action of gear 1023, the two driven gears 1026 cause the two slides 1024 to move closer synchronously, meaning the relative displacement of the two slides 1024 is always equal. This significantly increases the speed at which the rotary robotic arm assembly 4 approaches housing II 90, reducing the number of adjustments required by the robotic arm 60. Subsequently, the pressure cover assembly 3 fixes the housing, preventing it from moving freely. The mechanical finger 403 on the base 404 of the rotary robotic arm extends into the lower locking lever of the latch. The robotic arm 60 moves 5cm along the positive Z-axis of the three-axis palletizer. The spring assembly I 405 in the rotary robotic arm assembly 4 is compressed. During the rotation of the rotary robotic arm assembly 4, the spring assembly 405 applies a supporting force to the mechanical finger 403 to ensure that the mechanical finger 403 does not fall off the locking lever. During the unlocking process, the rotary robotic arm assembly 4 rotates upward 125°, the locking lever is lifted, the cylinder 502 in the locking lever assembly 5 extends, and the nylon push rod 506 at the end presses against the upper part of the latch against the housing II 90. At the same time, the spring assembly II 503 in the locking lever assembly 5 is compressed to prevent the upper part of the latch from moving during the movement, thereby preventing it from falling off. Its principle is the same as that of an embodiment of the present invention.

[0056] During the locking process, the robotic arm 60 moves away from the latch. Once the robotic finger 403 leaves the lower part of the latch, the spring in the latch causes the latch lever to automatically return. To ensure reliability, the robotic arm 60 is designed to move to the upper surface of the latch lever. During this movement, the latch assembly 5 remains stationary, keeping the latch close to the housing II 90 and connected to the locking hook on the lid. Then, the rotary robotic arm assembly 4 rotates downwards by 125° to engage the latch lever against the housing, completing the locking process.

[0057] In this embodiment, the movement of the entire robotic arm 60 is controlled by the slide table 1024. To ensure the synchronization of the movement of the robotic arm 60, the two slide tables 1024 are connected to each other by a gear set. When the power cylinder pushes the two slide tables 1024 to both sides, the gear set ensures that the movement of the robotic arm 60 always remains synchronized, maximizing the closing speed of the lock position of the housing and improving the efficiency of opening and closing the lock.

[0058] This invention provides a simple, efficient, and highly reliable automatic locking and unlocking device. A robotic arm is controlled by a three-axis palletizer to perform the relevant actions, and the locking and unlocking are separated, simplifying the process and improving reliability. Furthermore, by switching robotic arms for different types of locks, it adapts to the different locking and unlocking requirements, providing excellent adaptability.

[0059] The above description is merely an embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, extensions, etc., made within the spirit and principles of the present invention are included within the scope of protection of the present invention.
