Description
Technical Field
[0001] This application relates to the technical field of relay manufacturing, and in particular to a relay assembly mechanism. Background Technology
[0002] A relay assembly mechanism is a mechanism used to combine the relay base and the relay coil together. It mainly consists of a working platform and a clamping robotic arm. The working platform is used to support the relay base and keep it within the working range of the clamping robotic arm, while the clamping robotic arm is used to clamp the relay coil and install it on the base.
[0003] However, due to the small diameter of the relay coil pins, the corresponding diameter of the mounting holes in the relay base for pin insertion is also small. This can lead to the following situation when the gripping robot arm picks up the relay coil and installs it on the base: before being gripped, the small diameter of the relay coil pins, which are usually made of copper, makes them very easy to bend or deform. As a result, when the gripping robot arm picks up the relay coil and installs it on the base, the bent or deformed pins cannot be accurately inserted into the mounting holes of the base, leading to relay assembly errors. Therefore, this application proposes a relay assembly mechanism. Summary of the Invention
[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a relay assembly mechanism that solves the technical problem in the prior art where the pins of the relay coil cannot be accurately inserted into the mounting holes of the base, leading to relay assembly errors.
[0005] The above-mentioned objective of this application is achieved through the following technical solution: a relay assembly mechanism, including a working platform, a clamping robotic arm, and a correction component. The working platform is used to support a relay base, and the clamping robotic arm is used to clamp and transport a relay coil. The clamping robotic arm includes a dual-axis robotic arm, a clamping air pump, and a clamping pneumatic gripper. The dual-axis robotic arm is located on one side of the working platform. The clamping air pump is mounted on the moving end of the dual-axis robotic arm with its output end facing downwards. The clamping pneumatic gripper is mounted on the output end of the clamping air pump with both clamping ends facing downwards. The correction component is used to correct the pins of the relay coil during the clamping process of the clamping robotic arm clamping the relay coil.
[0006] Furthermore, the correction assembly includes a correction air pump, a correction pneumatic gripper, two connecting parts, two correction latches, and a connecting plate. The correction air pump is installed on the side of the work platform near the moving end of the gripping robot arm, with its output end facing upwards. The correction pneumatic gripper is vertically installed on the output end of the correction air pump. The two connecting parts are respectively fixedly installed on the two gripping ends of the correction pneumatic gripper. The correction air pump is used to control the two gripping ends of the correction pneumatic gripper to move closer or further apart. The ends of the two connecting parts away from the correction pneumatic gripper face the work platform. Extending in the direction, the two corrective claws are respectively fixedly installed on the ends of the two connecting parts away from the corrective pneumatic grippers. The connecting plate is located between the two connecting parts and is set on the corrective air pump. The end of the connecting plate away from the corrective air pump is flush with the corrective claws. When the corrective assembly is in the initial state, there is a gap between the two sides of the connecting plate and the connecting parts. The two sides of the connecting plate away from the corrective air pump are provided with corrective notches that are respectively opposite to the two corrective claws. When the corrective assembly is in the corrective state, the corrective notches and the corrective claws are combined together to form a corrective passage.
[0007] By adopting the above technical solution, the clamping robotic arm first picks up the relay coil, then moves the relay coil to above the end of the connecting plate near the straightening air pump. The clamping robotic arm then continues to move the relay coil downwards until the coil's pins insert into the gaps between the connecting plate and the connecting components on both sides. The clamping robotic arm then continues to move the relay coil away from the straightening air pump until the coil's pins abut against the straightening claws. At this point, the operator starts the straightening air pump. The pump outputs gas to drive the two clamping ends of the straightening pneumatic grippers closer together. This causes the two clamping ends of the straightening pneumatic grippers to move the two connecting components closer together. The moving connecting components then move the two straightening claws closer to the sides of the connecting plate, thus connecting the claws and the straightening... The notches combine to form a correction port. At this point, the pins of the relay coil are squeezed by the connecting claws and the connecting plate, which corrects the skewed or deformed pins of the relay coil, allowing them to be inserted into the mounting hole of the relay base. Then, the operator can restart the correction air pump. The air pump outputs gas to drive the two clamping ends of the correction pneumatic gripper away from each other, causing the connecting component to move the two correction claws away from both sides of the connecting plate. Then, the gripping robotic arm continues to move the relay coil above the relay base, and then the relay coil is installed on the relay base. This solves the technical problem in the prior art where the pins of the relay coil cannot be accurately inserted into the mounting hole of the base, causing relay assembly errors, and improves the yield rate of relay assembly production.
[0008] Furthermore, the working platform is equipped with an alignment device, which is used to drive the correction component to move towards the relay base so that the pins of the relay coil are aligned with the mounting holes of the relay base.
[0009] Furthermore, the alignment device includes a mounting plate, a telescopic device, a connecting block, a docking plate, and a support plate. One end of the mounting plate is fixedly installed on the side of the work platform away from the correction component, and the other end of the mounting plate extends away from the work platform. The telescopic device is installed on the end of the mounting plate away from the work platform, with the telescopic end of the telescopic device facing the side of the work platform where the correction component is located. The connecting block is fixedly installed on the telescopic end of the telescopic device. The docking plate is installed on the connecting block and is parallel to the work platform. The support plate is installed on the side of the docking plate near the correction component. The correction air pump is installed on the side of the work platform near the moving end of the gripping robotic arm via the support plate. There is a space between the support plate and the work platform for the support plate to move closer to or further away from the work platform.
[0010] While the above technical solution improves the yield rate of relay assembly production, in actual production, after the clamping robot arm corrects the pins of the relay coil, it is necessary to wait for the correction air pump in the correction assembly to restart, causing the correction claws to move away from the connecting plate or for the clamping robot arm to move upwards before the corrected relay coil can be installed on the relay base. This affects the efficiency of the clamping robot arm in installing the relay coil. The alignment device solves this technical problem. Through the alignment device, as the clamping robot arm moves the relay coil away from the correction air pump, the alignment process is completed. When the telescopic end of the first step is activated and retracted, the telescopic device, through the connecting block, docking plate, and bearing plate, drives the straightening air pump closer to the working platform. The straightening air pump then drives the connecting plate and the straightening claws closer to the working platform, moving the straightening opening formed by the straightening claws and the straightening notch directly above the relay base. Thus, after the relay coil is straightened, the gripping robot arm only needs to move downwards to install the relay coil on the relay base, without waiting for the straightening air pump in the straightening assembly to restart and move the straightening claws away from the connecting plate or control the gripping robot arm to move upwards. This improves the efficiency of installing the relay coil with the gripping robot arm.
[0011] Furthermore, the bottom of the work platform is provided with a positioning device for fixing the relay base.
[0012] Furthermore, the positioning device includes a positioning air pump, a positioning pneumatic gripper, and two positioning plates. The positioning air pump is located at the bottom of the working platform with its output end facing upwards. The positioning pneumatic gripper is installed on the output end of the positioning air pump, and its two clamping ends are located on both sides of the working platform. The top surface of the two clamping ends of the positioning pneumatic gripper is higher than the upper surface of the working platform. The two positioning plates are respectively installed on the top surface of the two clamping ends of the positioning pneumatic gripper.
[0013] While the above technical solution improves the yield rate of relay assembly production, the clamping robot arm generates vibrations during operation. These vibrations can affect the relay base on the work platform, causing it to shift position and preventing the relay coil, after being corrected by the correction component, from being accurately installed on the relay base. The positioning device solves this problem. When the relay base is transported to the work platform, the positioning air pump is activated, driving the positioning pneumatic gripper to bring its two gripping ends closer together. These gripping ends then bring the positioning plate into contact with both sides of the relay base, clamping and fixing it in place. This prevents the relay base from shaking due to the clamping robot arm, improving the accuracy and stability of the relay assembly clamping robot arm.
[0014] Furthermore, a protective component for protecting the relay base is placed on the working platform.
[0015] Furthermore, the protection component includes a protection plate, a limiting block, and a limiting post. The protection plate is placed on the working platform. Multiple limiting blocks are evenly distributed on the protection plate, and the space between the multiple limiting blocks is a placement space. The limiting posts are respectively and correspondingly set on both sides of the two clamping ends of the positioning pneumatic gripper of the protection plate. The limiting posts are vertically fixed on the protection plate. The end face of the positioning plate opposite to the limiting post has a snap-fit notch that matches the limiting post.
[0016] While the positioning device can prevent displacement or shaking of the relay base during assembly, in practical applications, the positioning device directly contacts the relay base via the positioning plate. This can lead to damage or deformation of the relay base when the positioning device clamps it. The protection component solves this problem. Before placing or transporting the relay base to the work platform, the operator can first place the relay base in the placement space composed of multiple limit blocks on the protection plate. Then, the protection plate with the relay base is transported or placed on the work platform. The positioning air pump is then activated, causing it to drive the two positioning plates towards the limit posts on both sides of the protection plate through the positioning pneumatic grippers. This allows the limit posts to engage in the locking notches, fixing the protection plate in place. This also prevents displacement or shaking of the relay base during assembly without direct contact, thus preventing damage or deformation of the relay base that might occur when the positioning device clamps it.
[0017] Furthermore, the working platform is provided with a protective device on the side away from the correction component to prevent the spring on the relay base from shifting or deforming.
[0018] Furthermore, the protective device includes a protective cylinder, a protective air pump, and a protective pneumatic gripper. The protective cylinder is installed on the side of the working platform away from the correction component and its output end faces the working platform. The protective air pump is installed at the output end of the protective cylinder and its output end faces the working platform. The protective pneumatic gripper is installed on the output end of the protective air pump. The two gripping ends of the protective pneumatic gripper are provided with protective notches for accommodating the spring pieces on the relay base.
[0019] By adopting the above technical solution, the existing technology involves installing a spring on the relay base. The core function of this spring is to ensure the reliability of the electrical connection and the stability of the mechanical structure. However, when the gripping robot arm installs the relay coil on the relay base, the proximity of the spring to the relay coil's installation position can cause the relay coil to collide with the spring, leading to spring displacement or deformation. The protective device solves this technical problem. By using the protective device, before the gripping robot arm installs the relay coil, the spring is positioned to prevent the relay base from colliding with the spring. After the relay is placed on the work platform, the output end of the protective cylinder is extended first, causing the protective air pump to drive the protective pneumatic gripper to move. This positions the two gripping ends of the protective pneumatic gripper on both sides of the spring on the relay base. Then, the protective air pump is activated to bring the two gripping ends of the protective pneumatic gripper closer together, causing the spring on the relay base to be wrapped by the protective notch. At this time, the protective pneumatic gripper holds the spring on the relay base, fixing the position of the spring on the relay base. This prevents the spring on the relay base from shifting or deforming, improving the stability of the robotic arm when installing the relay coil.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. By setting up the correction component, the clamping robot arm can promptly correct any misaligned or deformed pins of the relay coil during the process of installing the relay coil onto the relay base. This solves the technical problem in the prior art where the pins of the relay coil cannot be accurately inserted into the mounting holes of the base, leading to relay assembly errors, and improves the yield rate of relay assembly production.
[0022] 2. By setting up the alignment device, as the gripping robot arm moves away from the straightening air pump with the relay coil, the telescopic end of the telescopic device is simultaneously activated to retract. This causes the telescopic device to drive the straightening air pump closer to the work platform via the connecting block, docking plate, and bearing plate. The straightening air pump then drives the connecting plate and the straightening claws closer to the work platform, moving the straightening opening formed by the straightening claws and the straightening notch directly above the relay base. In this way, after the relay coil is straightened, the gripping robot arm only needs to move downwards to install the relay coil on the relay base, without waiting for the straightening air pump in the straightening assembly to restart and move the straightening claws away from the connecting plate or control the gripping robot arm to move upwards. This improves the efficiency of installing the relay coil with the gripping robot arm. Attached Figure Description

[0029] The present application will be further described in detail below with reference to the accompanying drawings.
[0030] Reference Figure 1 , Figure 2 , Figure 3 A relay assembly mechanism includes a working platform 1, a clamping robotic arm 2, and a correction component 3. The working platform 1 is used to support a relay base 8. The clamping robotic arm 2 is used to clamp and transport a relay coil. The clamping robotic arm 2 includes a dual-axis robotic arm, a clamping air pump, and a clamping pneumatic gripper. The dual-axis robotic arm is located on one side of the working platform 1. The clamping air pump is installed on the moving end of the dual-axis robotic arm with its output end facing downward. The clamping pneumatic gripper is installed on the output end of the clamping air pump with both clamping ends facing downward. The correction component 3 is used to correct the pins of the relay coil during the clamping process of the clamping robotic arm 2 clamping the relay coil.
[0031] The correction component 3 includes a correction air pump 30, a correction pneumatic gripper 31, two connecting parts 32, two correction latches 35, and a connecting plate 36. The correction air pump 30 is installed on the side of the work platform 1 near the moving end of the gripping robotic arm 2. The correction pneumatic gripper 31 is vertically installed on the output end of the correction air pump 30. The two connecting parts 32 are respectively fixedly installed on the two gripping ends of the correction pneumatic gripper 31. The correction air pump 30 is used to control the two gripping ends of the correction pneumatic gripper 31 to move closer or further apart. The end of the connecting part 32 away from the correction pneumatic gripper 31 extends towards the work platform 1. The two correction latches 35... The claws 35 are fixedly installed on the ends of the two connecting parts 32 away from the straightening pneumatic grippers 31, respectively. The connecting plate 36 is located between the two connecting parts 32 and is set on the straightening air pump 30. The end of the connecting plate 36 away from the straightening air pump 30 is flush with the straightening claws 35. When the straightening assembly 3 is in the initial state, there is a gap between the two sides of the connecting plate 36 and the connecting parts 32. The two sides of the connecting plate 36 away from the straightening air pump 30 are provided with straightening notches 37 that are respectively opposite to the two straightening claws 35. When the straightening assembly 3 is in the straightening state, the straightening notches 37 and the straightening claws 35 are combined together to form a straightening passage.
[0032] The working platform 1, the gripping robotic arm 2, and the corrective air pump 30 are all existing technologies and will not be described in detail here. Regarding the connecting component 32, it is specifically a long strip-shaped block that can be mounted on the corrective pneumatic gripper 31 using bolts, snap-fit connections, or other detachable fixing methods. Regarding the corrective clamp 35, it is specifically L-shaped, consisting of a corrective connecting rod and a corrective docking rod. One end of the corrective connecting rod is fixedly connected to the connecting component 32, while one end of the corrective docking rod is fixedly connected to the end of the corrective connecting rod furthest from the connecting component 32. The other end of the corrective docking rod extends towards the connecting plate 36. Regarding the initial state of the corrective assembly 3, when the corrective assembly 3 is in its initial state, the two connecting components 32 are far apart, a gap appears between the connecting plate 36 and the connecting component 32, and a wider gap also exists between the corrective pneumatic gripper 31 and the corrective notch 37 to allow the relay coil pins to pass through. Regarding the correction state of the correction component 3, when the correction component 3 is in the correction state, the two connecting parts 32 approach each other, so that the correction claw abuts against the edge of the correction notch 37, and combines with the correction notch 37 to form a correction passage for correcting the pins of the relay coil.
[0033] First, the gripping robotic arm 2 clamps the relay coil. Then, it moves the relay coil to a position above the end of the connecting plate 36 near the straightening air pump 30. Next, the gripping robotic arm 2 continues to move the relay coil downwards until its pins are inserted into the gaps between the sides of the connecting plate 36 and the connecting components 32. The gripping robotic arm 2 then continues to move the relay coil away from the straightening air pump 30 until its pins abut against the straightening claws 35. At this point, the operator starts the straightening air pump 30. The air pump outputs gas to drive the two gripping ends of the straightening pneumatic gripper 31 closer together. This causes the two gripping ends of the straightening pneumatic gripper 31 to move the two connecting components 32 closer together. The moving connecting components 32 then move the two straightening claws 35 closer to the sides of the connecting plate 36, thus connecting the claws and the straightening... The notches 37 are combined to form a correction opening. At this time, the pins of the relay coil are squeezed by the connecting claws and the connecting plate 36, so that the pins of the skewed or deformed relay coil are squeezed and corrected, so that they can be inserted into the mounting hole of the relay base 8. Then, the operator can restart the correction air pump 30. The correction air pump 30 outputs gas to drive the two clamping ends of the correction pneumatic gripper 31 to move away from each other, so that the connecting component 32 drives the two correction claws 35 to move away from the two sides of the connecting plate 36 respectively. Then, the clamping robot arm 2 continues to move the relay coil to the top of the relay base 8, and then installs the relay coil on the relay base 8. This solves the technical problem in the prior art that the pins of the relay coil cannot be accurately inserted into the mounting hole of the base, resulting in relay assembly errors, and improves the yield rate of relay assembly production.
[0034] In other embodiments, the correction component 3 includes a correction platform, a correction through hole, and a correction groove. The correction platform is located on the side of the working platform 1 near the moving end of the clamping robotic arm 2. The correction through hole is opened on the upper surface of the correction platform and its diameter is larger than the diameter of the pin of the relay coil. The correction groove is opened inside the correction platform and one end is connected to the correction through hole. The opening of the correction groove is located on the upper surface of the correction platform. The opening of the correction groove is conical and gradually narrows from the end of the correction groove connected to the correction through hole towards the working platform 1. When the pin of the relay coil needs to be corrected, the clamping robotic arm 2 is activated to clamp the relay coil. Then, the clamping robotic arm 2 moves the relay coil directly above the correction through hole. Subsequently, the clamping robotic arm 2 moves the relay coil downwards, so that the pin of the relay coil is inserted into the correction through hole. Then, the clamping robotic arm 2 moves the relay coil along the correction groove. This allows the relay coil pins to move within the correction groove. During this movement, the opening of the correction groove is tapered and gradually narrows from the end connecting the correction groove to the correction through-hole towards the working platform 1. This causes the relay coil pins to be gradually corrected as they move within the correction groove, thus correcting any misaligned or deformed pins. This solves the technical problem in the prior art where the relay coil pins cannot be accurately inserted into the mounting holes of the base, leading to relay assembly errors. Furthermore, compared to this embodiment, the embodiment using a correction platform, correction through-hole, and correction groove as the correction component 3 has a lower cost, requiring only the corresponding correction through-hole and correction groove to be formed on the correction platform. On the other hand, in the embodiment of the correction component 3 that uses a correction platform, correction through hole, and correction groove, the correction method is to hold the mechanical arm 2 and carry the relay coil pin through the correction groove. As the correction groove gradually shrinks, the pin of the relay coil will rub against the inner wall of the correction groove during the correction process. After a long period of use, the correction groove will expand, affecting the subsequent correction effect. In this embodiment, the correction air pump 30 drives the correction pneumatic grippers 31 to move closer to each other, so that the correction clips 35 and correction notches 37 combine to press the pin of the relay coil. In this process, the correction clips 35 and correction notches 37 will not generate too much wear. Therefore, the correction component 3 in this embodiment has a longer service life than the embodiment of the correction component 3 that uses a correction platform, correction through hole, and correction groove. In actual use, the choice can be made according to the needs. For example, if mass production is possible and the production cost is sufficient, the correction group in this embodiment can be used. If small-batch production is possible and the production cost is low, the embodiment of correction component 3, which adopts a correction platform, correction through hole and correction groove, can be used.
[0035] Although the setting of the straightening component 3 improves the yield rate of relay assembly production, in the actual production process, after the clamping robot arm 2 drives the relay coil to straighten the pins, it is still necessary to wait for the straightening air pump 30 in the straightening component 3 to start again to move the straightening claw 35 away from the connecting plate 36 or control the clamping robot arm 2 to move upward before the straightened relay coil can be installed on the relay base 8. This affects the efficiency of the clamping robot arm 2 in installing the relay coil. In order to solve this technical problem, this embodiment provides an alignment device 4 on the working platform 1. The alignment device 4 is used to drive the straightening component 3 to move towards the relay base 8 so that the pins of the relay coil are aligned with the mounting holes of the relay base 8. The alignment device 4 includes a mounting plate 40, a telescopic device 41, a connecting block 42, and a docking plate 4. 3 and a support plate 44, one end of the mounting plate 40 is fixedly installed on the side of the working platform 1 away from the correction component 3, and the other end of the mounting plate 40 extends away from the working platform 1. The telescopic device 41 is installed on the end of the mounting plate 40 away from the working platform 1, and the telescopic end of the telescopic device 41 faces the side of the working platform 1 where the correction component 3 is located. The connecting block 42 is fixedly installed on the telescopic end of the telescopic device 41. The docking plate 43 is installed on the connecting block 42 and is parallel to the working platform 1. The support plate 44 is installed on the side of the docking plate 43 close to the correction component 3. The correction air pump 30 is installed on the side of the working platform 1 close to the moving end of the gripping robot arm 2 through the support plate 44. There is a space between the support plate 44 and the working platform 1 for the support plate 44 to move closer to or away from the working platform 1.
[0036] The mounting plate 40 can be installed on the work platform 1 by welding, bolting, or other fixing methods. The telescopic device 41 can be a pneumatic cylinder, electric cylinder, or hydraulic cylinder. The connecting block 42 can be installed on the telescopic end of the telescopic device 41 by welding, bolting, or other fixing methods. The docking plate 43 can be installed on the connecting block 42 by welding, bolting, or other fixing methods. The bearing plate 44 is installed on the docking plate 43 by welding, bolting, or other fixing methods. The straightening air pump 30 can be installed on the bearing plate 44 by bolting, snap-fitting, or other detachable fixing methods.
[0037] By setting up the alignment device 4, as the gripping robotic arm 2 moves away from the straightening air pump 30 with the relay coil, the telescopic end of the telescopic device 41 is simultaneously activated to retract. This causes the telescopic device 41 to drive the straightening air pump 30 closer to the working platform 1 via the connecting block 42, the docking plate 43, and the bearing plate 44. The straightening air pump 30 then drives the connecting plate 36 and the straightening claw 35 closer to the working platform 1, so that the straightening passage formed by the straightening claw 35 and the straightening notch 37 moves to the top of the relay base 8. In this way, after the relay coil is straightened, the gripping robotic arm 2 only needs to move down to install the relay coil on the relay base 8, without waiting for the straightening air pump 30 in the straightening assembly 3 to start again to move the straightening claw 35 away from the connecting plate 36 or to control the gripping robotic arm 2 to move up, thereby improving the efficiency of the gripping robotic arm 2 in installing the relay coil.
[0038] Although the setting of the correction component 3 improves the yield rate of relay assembly production, in actual production, the gripping robotic arm 2 will generate a certain amount of vibration during operation. This vibration may affect the relay base 8 on the work platform 1, causing the relay base 8 to shift position, making it impossible for the relay coil after correction by the correction component 3 to be accurately installed on the relay base 8. To solve this technical problem, this embodiment provides a positioning device 5 for fixing the relay base 8 at the bottom of the work platform 1, referring to... Figure 4 The positioning device 5 includes a positioning air pump 50, a positioning pneumatic gripper 51, and two positioning plates 52. The positioning air pump 50 is located at the bottom of the working platform 1 with its output end facing upward. The positioning pneumatic gripper 51 is installed on the output end of the positioning air pump 50, and its two clamping ends are located on both sides of the working platform 1. The top surface of the two clamping ends of the positioning pneumatic gripper is higher than the upper surface of the working platform 1. The two positioning plates 52 are respectively installed on the top surface of the two clamping ends of the positioning pneumatic gripper.
[0039] The working platform 1 specifically consists of a working plate and two support rods. The two support rods are located on the front and rear sides of the bottom of the working plate and are fixedly connected to the working plate. The working plate is used to support the relay base 8. The positioning air pump 50 is specifically located at the bottom of the working plate and between the two support rods, and the positioning air pump 50 is installed in the space relative to the ground at the bottom of the working plate. The positioning plate 52 can be installed on the clamping end of the positioning pneumatic gripper 51 by welding, bolts, or other fixing methods. In other embodiments, the working platform 1 can also be a parallel assembly line output machine.
[0040] With the positioning device 5 in place, when the relay base 8 is transported to the work platform 1, the positioning air pump 50 is activated. The positioning air pump 50 drives the positioning pneumatic gripper 51 so that the two gripping ends of the positioning pneumatic gripper 51 move closer to each other. The two gripping ends move closer to each other and drive the positioning plate 52 to contact the two sides of the relay base 8, so that the positioning plate 52 clamps and fixes the relay base 8, thereby preventing the relay base 8 from shaking due to the influence of the gripping robotic arm 2, and improving the accuracy and stability of gripping the robotic arm 2 to combine the relay.
[0041] Although the positioning device 5 can prevent the relay base 8 from shifting or shaking during assembly, in practical applications, since the positioning device 5 directly contacts the relay base 8 through the positioning plate 52, the positioning device 5 may cause damage or deformation to the relay base 8 when clamping it. To solve this technical problem, this embodiment places a protective component 6 on the working platform 1 to protect the relay base 8. (Refer to...) Figure 5 The protection component 6 includes a protection plate 60, a limiting block 61, and a limiting post 62. The protection plate 60 is placed on the working platform 1. Multiple limiting blocks 61 are evenly distributed on the protection plate 60, and the space between the multiple limiting blocks 61 is the placement space. The limiting posts 62 are respectively set on both sides of the two clamping ends of the positioning pneumatic gripper 51 of the protection plate 60. The limiting posts 62 are vertically fixed on the protection plate 60. The end face of the positioning plate 52 relative to the limiting post 62 has a matching snap-fit notch 53.
[0042] The specific number of the multiple limit blocks 61 can be determined according to the shape of the relay base 8. For example, if the relay base 8 is rectangular, the number of limit blocks 61 can be set to four, and they can be set on the periphery of the protection plate 60 according to the size of the relay base 8 to limit the relay base 8.
[0043] With the protection component 6 in place, before placing or transporting the relay base 8 to the work platform 1, the operator can first place the relay base 8 in the placement space composed of multiple limiting blocks 61 on the protection plate 60. Then, the protection plate 60 with the relay base 8 is transported or placed on the work platform 1. The positioning air pump 50 is then started, which drives the two positioning plates 52 to approach the limiting posts 62 on both sides of the protection plate 60 through the positioning pneumatic gripper 51. This causes the limiting posts 62 to engage in the snap-fit notch 53, thus fixing the protection plate 60. This also prevents the relay base 8 from shifting or shaking during the assembly process, and it does not require direct contact with the relay base 8, preventing damage or deformation of the relay base 8 that may occur when the positioning device 5 clamps it.
[0044] In the prior art, a spring is installed on the relay base 8. The core function of the spring is to ensure the reliability of the electrical connection and the stability of the mechanical structure. However, when the clamping robot arm 2 installs the relay coil on the relay base 8, the spring is close to the installation position of the relay coil. This can cause the relay coil to collide with the spring, resulting in the spring shifting or deforming. Based on this, this embodiment provides a protective device 7 on the side of the working platform 1 away from the correction component 3 to prevent the spring on the relay base 8 from shifting or deforming. The protective device 7 includes a protective cylinder 70, a protective air pump 71, and a protective pneumatic gripper 72. The protective cylinder 70 is installed on the side of the working platform 1 away from the correction component 3 with its output end facing the working platform 1. The protective air pump 71 is installed at the output end of the protective cylinder 70 with its output end facing the working platform 1. The protective pneumatic gripper 72 is installed on the output end of the protective air pump 71. The two clamping ends of the protective pneumatic gripper 72 are provided with protective notches 73 for accommodating the spring on the relay base 8.
[0045] With the protective device 7 in place, before the relay coil is installed on the gripping robotic arm 2, after the relay base 8 is transported or placed on the work platform 1, the output end of the protective cylinder 70 is first extended, causing the protective air pump 71 to drive the protective pneumatic gripper 72 to move. This causes the two gripping ends of the protective pneumatic gripper 72 to be located on both sides of the spring piece on the relay base 8. Then, the protective air pump 71 is activated to bring the two gripping ends of the protective pneumatic gripper 72 closer together, so that the spring piece on the relay base 8 is wrapped by the protective notch 73. At this time, the protective pneumatic gripper 72 holds the spring piece on the relay base 8, fixing the position of the spring piece on the relay base 8, thereby preventing the spring piece on the relay base 8 from shifting or deforming, and improving the stability of the gripping robotic arm 2 when installing the relay coil.
[0046] 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.
