Description

Technical Field

[0001] This application relates to the technical field of relay manufacturing, and in particular to a relay spring mounting mechanism. Background Technology

[0002] The relay spring mounting mechanism is used to install the relay springs onto the relay base. It includes a vibrating screen and a clamping robotic arm. The vibrating screen sorts and arranges the springs, and then the conveying device of the vibrating screen transports them to the discharge end of the vibrating screen. At this time, the clamping robotic arm picks up the springs on the discharge end of the vibrating screen and moves them above the base. Then, the clamping robotic arm moves down so that the springs are inserted into the base, completing the installation of the springs.

[0003] However, in the prior art, there is a type of relay in which multiple springs are mounted on the base in a rectangular array. However, because the space for mounting multiple springs on the base is small, the spacing between the multiple springs is small. This causes the gripping end of the gripping robot to contact other springs when it inserts the springs into the base, which may cause other springs to deform, resulting in poor contact or increased resistance of the relay. Therefore, this application proposes a relay spring mounting mechanism. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a relay spring mounting mechanism to prevent the clamping end of the gripping robot arm from contacting other springs and causing deformation of those springs during the installation process.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a relay spring mounting mechanism, including a vibrating screen, a clamping robotic arm, and a limiting component. The vibrating screen is installed on one side of the working position and is used to screen and arrange springs for clamping by the clamping robotic arm. The clamping robotic arm includes a dual-axis robotic arm, a connecting collar, a first clamping air pump, and a first pneumatic gripper. The dual-axis robotic arm is installed between the vibrating screen and the working position and is used to move the first clamping air pump and the connecting collar. The connecting collar is vertically slidably installed on the moving end of the dual-axis robotic arm. The first clamping air pump is vertically slidably installed on the moving end of the dual-axis robotic arm and fixedly connected to the connecting collar. The connecting collar surrounds the first clamping air pump. The first pneumatic gripper is installed on the output end of the first clamping air pump and is used to clamp the spring. The limiting component is installed in the working position and is used to limit the downward movement of the first clamping air pump.

[0006] By adopting the above technical solution, the vibrating screen plate sorts and arranges the spring pieces, which are then transported to the discharge end of the vibrating screen plate by the conveying device. At this time, the moving end of the dual-axis robotic arm drives the first pneumatic gripper to move above the spring pieces at the discharge end of the vibrating screen plate. The output end of the first clamping air pump outputs gas to drive the first pneumatic gripper to clamp the spring pieces. Then, the moving end of the dual-axis robotic arm drives the first pneumatic gripper to move to the base of the relay in the working position, aligning the spring pieces with the mounting holes of the base. Subsequently, the moving end of the dual-axis robotic arm moves down, inserting the spring pieces into the base. During the process, when the moving end of the dual-axis robotic arm moves downward, it will simultaneously drive the connecting collar, the first clamping air pump, and the first pneumatic gripper to move downward. However, due to the limitation of the limiting component, the first clamping air pump will be blocked by the limiting component during the downward movement. This causes the connecting collar to drive the first clamping air pump and the first pneumatic gripper to move upward along the moving end of the dual-axis robotic arm, so that only the bottom end of the spring is inserted into the mounting hole of the base. In this way, the first pneumatic gripper will not squeeze other springs, preventing the clamping end of the robotic arm from contacting other springs and causing other springs to deform.

[0007] Furthermore, the limiting assembly includes two support rods and one limiting rod. The two support rods are installed at a distance from each other in the working position. The two ends of the limiting rod are respectively fixedly connected to the upper ends of the two support rods and are used to abut against the first clamping air pump.

[0008] By adopting the above technical solution, when the moving end of the dual-axis robotic arm moves downward, it synchronously drives the connecting collar, the first clamping air pump, and the first pneumatic gripper to move downward. The first clamping air pump will be blocked by the limiting rod when it moves downward. As the moving end of the dual-axis robotic arm continues to move downward, the connecting collar, the first clamping air pump, and the first pneumatic gripper will slide upward on the moving end due to the limitation of the limiting rod. This allows only the bottom end of the spring to be inserted into the mounting hole of the base. In this way, the first pneumatic gripper will not squeeze other springs, preventing the clamping end of the robotic arm from contacting other springs and causing other springs to deform.

[0009] Furthermore, the clamping end of the first pneumatic gripper is provided with a pressing component for pressing the spring sheet.

[0010] Furthermore, the pressing assembly includes a pressing rod and a connecting rod. The pressing rod is vertically slidably inserted into the middle of the clamping end of the first pneumatic gripper. One end of the connecting rod is fixedly connected to the pressing rod, and the other end of the connecting rod passes through the first pneumatic gripper and is fixedly connected to the moving end of the dual-axis robotic arm. The first pneumatic gripper has a vertically formed moving groove for the connecting rod to move up and down. The connecting rod is located below the connecting collar.

[0011] While the aforementioned technical solution prevents the clamping arm from contacting other springs and causing deformation, the limitation imposed by the limit component restricts the clamping arm to insert only the bottom of the spring into the mounting hole of the base. This necessitates subsequent pressing of the spring to fully install it onto the base, which is inconvenient. The pressing component solves this problem. By using the pressing component, when the connecting collar, the first clamping air pump, and the first pneumatic gripper are stopped by the limit rod... When the limiting mechanism slides upward on the moving end, because the connecting rod is directly fixed to the moving end of the dual-axis robotic arm, the abutment rod connected to the connecting rod will not slide upward with the connecting collar, the first clamping air pump, and the first pneumatic gripper. Instead, it will continue to move downward with the moving end of the dual-axis robotic arm, causing the abutment rod to press against the top surface of the spring piece, pressing the remaining part of the spring piece into the base, so that the spring piece is completely installed on the base. At the same time, because the abutment rod only abuts against the top surface of the spring piece, it will not occupy the space around the spring piece and will not affect other spring pieces.

[0012] Furthermore, the moving end of the dual-axis robotic arm is provided with a reset assembly for resetting the connecting collar, the first clamping air pump, and the first pneumatic gripper.

[0013] Furthermore, the reset assembly includes a reset collar and a reset spring. The reset collar is fixedly sleeved on the upper end of the moving end of the dual-axis robotic arm and located above the connecting collar. One end of the reset spring is fixedly connected to the reset collar, and the other end of the reset spring is fixedly connected to the connecting collar. The reset spring is used to push the connecting collar to reset.

[0014] By adopting the above technical solution, although the limiting component, together with the gripping robot arm, can prevent the gripping end of the gripping robot arm from contacting other springs and causing deformation of those springs, the connecting collar may get stuck after being pushed upward by the limiting component. This could prevent the first pneumatic gripper from resetting, leading to errors in subsequent processing. The reset component solves this technical problem. When the connecting collar slides upward on the moving end, it presses against the reset spring, causing it to contract. After the dual-axis robot arm resets, the connecting collar disengages from the limiting component. At this point, the reset spring releases its elasticity, pushing the connecting collar back to its original position. This causes the connecting collar to reset the first pneumatic gripper and the first gripping air pump, preventing the first pneumatic gripper from failing to reset and causing errors in subsequent processing.

[0015] Furthermore, a positioning mechanism is provided on one side of the gripping robotic arm. The positioning mechanism is positioned relative to the gripping robotic arm and installed on the side of the working position relative to the gripping robotic arm. The positioning mechanism is used to fix the base of the relay.

[0016] Furthermore, the positioning mechanism includes a clamping cylinder, a second clamping air pump, and a second pneumatic gripper. The clamping cylinder is installed on the side of the working position opposite to the clamping robot arm with its output end facing the clamping robot arm. The second clamping air pump is installed on the output end of the clamping cylinder, and the second pneumatic gripper is installed on the output end of the second clamping air pump. The second clamping air pump is used to drive the second pneumatic gripper to perform clamping movements.

[0017] By adopting the above technical solution and setting the positioning mechanism, when the base of the relay moves to the working position and the positioning mechanism and the clamping robot arm are respectively positioned on both sides, the operator can activate the extension of the clamping cylinder, so that the output end of the clamping cylinder pushes the second clamping air pump and the second pneumatic gripper, so that the clamping end of the second pneumatic gripper moves to both sides of the base. Then, the second clamping air pump is activated again, so that the second pneumatic gripper clamps the base and fixes the base, so that the clamping robot arm can work on the base in the future.

[0018] Furthermore, a rolling assembly is provided on one side of the limiting rod, which is used to reduce the wear of the first clamping air pump.

[0019] Furthermore, the rolling assembly includes a connecting shaft and a rolling wheel. The connecting shaft is fixedly mounted on one side of the limiting rod, and the rolling wheel is rotatably mounted on the connecting shaft. The upper end of the rolling wheel is higher than the top surface of the limiting rod.

[0020] By adopting the above technical solution, although the limiting component, together with the gripping robotic arm, can prevent the gripping end of the robotic arm from contacting other springs and causing deformation of those springs, the moving end of the dual-axis robotic arm not only drives the first gripping air pump to move up and down, but also to move it horizontally. This causes the first gripping air pump to rub against the limiting rod, resulting in severe wear of the first gripping air pump and reducing its service life. The rolling component solves this technical problem. When the moving end of the dual-axis robotic arm moves downward, it simultaneously drives the connecting collar, the first clamping air pump, and the first pneumatic gripper downward. Since the upper end of the rolling wheel is higher than the top surface of the limiting rod, the rolling wheel will contact the first clamping air pump, limiting the first clamping air pump and preventing the first pneumatic gripper from moving downward. At the same time, since the rolling wheel is rotatably mounted on the connecting shaft, when the moving end of the dual-axis robotic arm drives the first clamping air pump to move horizontally, the rolling wheel will roll, reducing the friction between the first clamping air pump and the rolling wheel, thereby improving the service life of the first clamping air pump.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By setting up a clamping robotic arm and a limiting component, during the process of installing spring pieces in the clamping robotic arm, the limiting component will restrict the downward movement of the first pneumatic gripper in the clamping robotic arm, so that only the bottom end of the spring piece is inserted into the mounting hole of the base. In this way, the first pneumatic gripper will not squeeze other spring pieces, preventing the clamping end of the clamping robotic arm from contacting other spring pieces and causing other spring pieces to deform, thereby improving the yield rate of relay production.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1 , Figure 2A relay spring mounting mechanism includes a vibrating screen 1, a clamping robotic arm 2, and a limiting assembly 3. The vibrating screen 1 is installed on one side of a working position 8 and is used to screen and arrange springs for clamping by the clamping robotic arm 2. The clamping robotic arm 2 includes a dual-axis robotic arm 20, a connecting collar 21, a first clamping air pump 22, and a first pneumatic gripper 23. The dual-axis robotic arm 20 is installed between the vibrating screen 1 and the working position 8 and is used to move the first gripper. The first clamping air pump 22 and the connecting collar 21 are vertically slidably mounted on the moving end of the dual-axis robotic arm 20. The first clamping air pump 22 is vertically slidably mounted on the moving end of the dual-axis robotic arm 20 and fixedly connected to the connecting collar 21. The connecting collar 21 surrounds the first clamping air pump 22. The first pneumatic gripper 23 is mounted on the output end of the first clamping air pump 22 and is used to clamp the spring. The limiting component 3 is mounted on the working position 8 and is used to limit the downward movement of the first clamping air pump 22.

[0030] The vibrating screening disc 1 is existing technology and will not be described in detail here. The dual-axis robotic arm 20 is a mechanical device with two degrees of freedom, consisting of a base, two movable joints (rotational or translational), and an end effector. It can achieve precise movement in a two-dimensional plane or a specific space. The moving end of the dual-axis robotic arm 20 is the end effector, which can move precisely in a two-dimensional plane or a specific space, carrying the connecting collar 21, the first clamping air pump 22, and the first pneumatic gripper 23. The connecting collar 21 is rectangular in shape and surrounds the moving end of the dual-axis robotic arm 20. The first clamping air pump 22 and the first pneumatic gripper 23 are both existing technologies and will not be described in detail here. The working position 8 is mainly the placement position of the relay base 9, such as on an assembly line or work platform; that is, the working position 8 is the position where the relay base 9 rests or is placed. The limiting component 3 specifically includes two support rods 30 and a limiting rod 31. The two support rods 30 are installed at a relatively interval on the working position 8. The two ends of the limiting rod 31 are respectively fixedly connected to the upper ends of the two support rods 30 and are used to abut against the first clamping air pump 22.

[0031] The spring pieces are sorted and arranged by the vibrating screen 1, and then transported to the discharge end of the vibrating screen 1 by the conveying device of the vibrating screen 1. At this time, the moving end of the dual-axis robotic arm 20 drives the first pneumatic gripper 23 to move above the spring pieces at the discharge end of the vibrating screen 1. The output end of the first clamping air pump 22 outputs gas to drive the first pneumatic gripper 23 to clamp the spring pieces. Then, the moving end of the dual-axis robotic arm 20 drives the first pneumatic gripper 23 to move above the base 9 of the relay at the working position 8, and aligns the spring pieces with the mounting holes of the base 9. Subsequently, the moving end of the dual-axis robotic arm 20 moves down and inserts the spring pieces into the mounting holes of the base 9. During this process, when the moving end of the dual-axis robotic arm 20 moves downward, it will simultaneously drive the connecting collar 21, the first clamping air pump 22, and the first pneumatic gripper 23 to move downward. However, due to the limitation of the limiting component 3, the first clamping air pump 22 will be blocked by the limiting component 3 during the downward movement, causing the connecting collar 21 to drive the first clamping air pump 22 and the first pneumatic gripper 23 to move upward along the moving end of the dual-axis robotic arm 20, so that only the bottom end of the spring is inserted into the mounting hole of the base 9. In this way, the first pneumatic gripper 23 will not squeeze other springs, preventing the clamping end of the clamping robotic arm 2 from contacting other springs and causing other springs to deform.

[0032] In this embodiment, the limiting component 3 includes two support rods 30 and a limiting rod 31. The two support rods 30 are installed at a distance from each other on the working position 8. The two ends of the limiting rod 31 are fixedly connected to the upper ends of the two support rods 30 and are used to abut against the first clamping air pump 22.

[0033] Specifically, two support rods 30 and one limiting rod 31 form a gate-shaped bracket. The two support rods 30 can be installed on both sides of the working position 8 to allow the base 9 of other relays to pass through. Taking an assembly line as an example, the two support rods 30 are installed on both sides of the assembly line, and the limiting rod 31 is fixedly installed on the top of the two support rods 30 to form a gate-shaped bracket. In this way, the base 9 of the assembly line can pass through the gap between the two support rods 30. At the same time, the gate-shaped bracket formed by the support rods 30 and the limiting rod 31 can restrict the first clamping air pump 22.

[0034] When the moving end of the dual-axis robotic arm 20 moves downward, it synchronously drives the connecting collar 21, the first clamping air pump 22, and the first pneumatic gripper 23 to move downward. The first clamping air pump 22 will be blocked by the limiting rod 31. As the moving end of the dual-axis robotic arm 20 continues to move downward, the connecting collar 21, the first clamping air pump 22, and the first pneumatic gripper 23 will slide upward on the moving end due to the limitation of the limiting rod 31. This will cause the spring piece to be inserted into the mounting hole of the base 9 only at its bottom end. In this way, the first pneumatic gripper 23 will not squeeze other spring pieces, preventing the clamping end of the robotic arm 2 from contacting other spring pieces and causing other spring pieces to deform.

[0035] Although the limiting component 3, in conjunction with the gripping robotic arm 2, can prevent the gripping end of the robotic arm 2 from contacting other spring pieces and causing deformation of those spring pieces, the limitation imposed by the limiting component 3 means that the gripping robotic arm 2 can only insert the bottom end of the spring piece into the mounting hole of the base 9. This requires subsequent workers to press the spring piece again to fully install it onto the base 9, which is very inconvenient. To solve this technical problem, this embodiment provides a pressing component for pressing the spring piece in the middle of the gripping end of the first pneumatic gripper 23, as shown in the figure. Figure 3 The pressing component includes a pressing rod 4 and a connecting rod (not shown in the figure). The pressing rod 4 is vertically slidably inserted into the middle of the clamping end of the first pneumatic gripper 23. One end of the connecting rod is fixedly connected to the pressing rod 4, and the other end of the connecting rod passes through the first pneumatic gripper 23 and is fixedly connected to the moving end of the dual-axis robotic arm 20. The first pneumatic gripper 23 has a vertically opened moving groove (not shown in the figure) for the connecting rod to move up and down. The connecting rod is located below the connecting collar 21.

[0036] Specifically, the abutment rod 4 and the connecting rod combine to form an L-shaped rod. The L-shaped rod is located inside the first pneumatic gripper 23, with one end extending vertically downward from the middle of the gripping end of the first pneumatic gripper 23, and the other end extending laterally towards the moving end of the dual-axis robotic arm 20 and fixedly connected to the dual-axis robotic arm 20.

[0037] By setting up the abutment component, when the connecting collar 21, the first clamping air pump 22, and the first pneumatic gripper 23 slide upward on the moving end due to the limitation of the limiting rod 31, since the connecting rod is directly fixed to the moving end of the dual-axis robotic arm 20, the abutment rod 4 connected to the connecting rod will not slide upward with the connecting collar 21, the first clamping air pump 22, and the first pneumatic gripper 23. Instead, it will continue to move downward with the moving end of the dual-axis robotic arm 20, so that the abutment rod 4 abuts the top surface of the spring piece, pressing the remaining part of the spring piece into the base 9, so that the spring piece is completely installed on the base 9. At the same time, since the abutment rod 4 only abuts the top surface of the spring piece, it will not occupy the space around the spring piece and will not affect other spring pieces.

[0038] Although the limiting component 3, in conjunction with the gripping robotic arm 2, can prevent the gripping end of the gripping robotic arm 2 from contacting other springs and causing deformation of those springs, the connecting collar 21 may get stuck after being pushed upwards by the limiting component 3. This could prevent the first pneumatic gripper 23 from resetting, leading to errors in subsequent processing. To solve this technical problem, this embodiment provides a resetting component 5 on the moving end of the dual-axis robotic arm 20 to reset the connecting collar 21, the first gripping air pump 22, and the first pneumatic gripper 23. (Refer to...) Figure 2The reset assembly 5 includes a reset collar 50 and a reset spring 51. The reset collar 50 is fixedly sleeved on the upper end of the moving end of the dual-axis robotic arm 20 and located above the connecting collar 21. One end of the reset spring 51 is fixedly connected to the reset collar 50, and the other end of the reset spring 51 is fixedly connected to the connecting collar 21. The reset spring 51 is used to push the connecting collar 21 to reset.

[0039] With the reset component 5 in place, when the connecting collar 21 slides upward on the moving end, the sliding connecting collar 21 will press the reset spring 51, causing the reset spring 51 to contract. Thus, after the dual-axis robotic arm 20 resets, the connecting collar 21 disengages from the limiting component 3 along with the reset of the dual-axis robotic arm 20. At this time, the reset spring 51 releases its elastic force, pushing the connecting collar 21 to reset, causing the connecting collar 21 to drive the first pneumatic gripper 23 and the first clamping air pump 22 to reset, preventing the first pneumatic gripper 23 from failing to reset and causing errors in subsequent processing.

[0040] Although the limiting component 3, in conjunction with the gripping robotic arm 2, can prevent the gripping end of the robotic arm 2 from contacting other springs and causing deformation of those springs, the moving end of the dual-axis robotic arm 20 not only drives the first gripping air pump 22 to move up and down, but also to move it horizontally. This causes the first gripping air pump 22 to rub against the limiting rod 31, resulting in significant wear on the first gripping air pump 22 and reducing its service life. To solve this technical problem, refer to... Figure 4 In this embodiment, a rolling assembly 7 is provided on one side of the limiting rod 31. The rolling assembly 7 includes a connecting shaft 70 and a rolling wheel 71. The connecting shaft 70 is fixedly disposed on one side of the limiting rod 31, and the rolling wheel 71 is rotatably mounted on the connecting shaft 70. The upper end of the rolling wheel 71 is higher than the top surface of the limiting rod 31.

[0041] When the moving end of the dual-axis robotic arm 20 moves downward, it synchronously drives the connecting collar 21, the first clamping air pump 22, and the first pneumatic gripper 23 to move downward. Since the upper end of the rolling wheel 71 is higher than the top surface of the limiting rod 31, the rolling wheel 71 will contact the first clamping air pump 22, limiting the first clamping air pump 22 and preventing the first pneumatic gripper 23 from moving downward. At the same time, since the rolling wheel 71 is rotatably mounted on the connecting shaft 70, when the moving end of the dual-axis robotic arm 20 drives the first clamping air pump 22 to move horizontally, the rolling wheel 71 will roll, reducing the friction between the first clamping air pump 22 and the rolling wheel 71, thereby improving the service life of the first clamping air pump 22.

[0042] In this embodiment, a positioning mechanism 6 is provided on one side of the clamping robotic arm 2. The positioning mechanism 6 is positioned relative to the clamping robotic arm 2 and installed on the side of the working position 8 relative to the clamping robotic arm 2. The positioning mechanism 6 is used to fix the base 9 of the relay. The positioning mechanism 6 includes a clamping cylinder 60, a second clamping air pump 61, and a second pneumatic gripper 62. The clamping cylinder 60 is installed on the side of the working position 8 relative to the clamping robotic arm 2 and its output end faces the clamping robotic arm 2. The second clamping air pump 61 is installed on the output end of the clamping cylinder 60, and the second pneumatic gripper 62 is installed on the output end of the second clamping air pump 61. The second clamping air pump 61 is used to drive the second pneumatic gripper 62 to perform clamping movement.

[0043] With the positioning mechanism 6 in place, when the base 9 of the relay moves to the working position 8 and the positioning mechanism 6 and the gripping robot arm 2 are respectively positioned on both sides, the operator can activate the extension of the gripping cylinder 60, so that the output end of the gripping cylinder 60 pushes the second gripping air pump 61 and the second pneumatic gripper 62, so that the gripping end of the second pneumatic gripper 62 moves to both sides of the base 9. Then the second gripping air pump 61 is activated again, so that the second pneumatic gripper 62 grips the base 9 and fixes the base 9, so that the gripping robot arm 2 can work on the base 9 in the future.

[0044] The embodiments described in this specific implementation are 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.
