[0073] The present invention is further described below with reference to specific embodiments:

[0074] An assembly device for a relay moving contact, such as Figure 1-3 As shown, it includes a frame 1, an assembly base 2, a first assembly device 3 for installing a dynamic retaining spring 74, a second assembly device 4 for installing a dynamic contact piece 73, two third assembly devices 5 for respectively installing an upper spring 75 and a lower spring 72, and a discharge device 6. The frame 1 is generally square in shape, and a mounting surface 11 is formed on its upper surface for mounting the assembly base 2, the first assembly device 3, the second assembly device 4, the third assembly device 5, and the discharge device 6. The assembly base 2 is disposed on the frame 1 and is connected to a fourth feeding assembly 21. The fourth feeding assembly 21 is used to transport the main rod 71 to the assembly base 2 and be positioned in the assembly base 2. The lower spring 72, the dynamic contact piece 73, the retaining spring 74, and the upper spring 75 are then installed in sequence by the first assembly device 3, the second assembly device 4, and the third assembly device 5, and then the main rod is removed from the assembly base 2 by the discharge device 6.

[0075] The structure of this patent is introduced below in the order of assembly. Figure 4 、 5As shown, an assembly groove 22 is provided in the assembly seat 2, and the assembly groove 22 has a loading position 2a and an assembly position 2b. A loading groove 23 is provided at the loading position 2a to intersect with the assembly groove 22, and the loading groove 23 is connected to the fourth feeding component 21; a positioning groove 24 is provided at the assembly position 2b to intersect with the assembly groove 22.

[0076] Specific reference Figure 5 In this embodiment, the fourth feeding assembly 21 is a vibration plate fixed to the frame 1, and the vibration plate is connected to a conveying track adapted to the shape of the main rod 71, and the conveying track is connected to the assembly seat 2. The assembly seat 2 is specifically a profile fixed to the frame 1, and a transverse assembly groove 22 is formed in the profile. One end of the assembly groove 22 is provided with an opening, and a loading push rod 221 is provided on the outside of the assembly groove 22. The loading push rod 221 is driven by a cylinder, and the loading drag rod passes through the opening at one end of the assembly groove 22 to enter the assembly groove 22 and move along the assembly groove 22; the loading push rod 221 is provided with the grabbing notch 2211, which is specifically an arc-shaped notch provided on one side of the loading push rod 221, and the curvature of the arc-shaped notch is adapted to one side of the main rod 71.

[0077] Combine Figure 4 As shown, with the direction of movement of the loading push rod 221 as a reference, when the loading push rod 221 is retracted, the position of the grabbing notch 2211 is the loading position 2a. At this time, the loading position 2a is provided with a loading trough 23 that is connected to the assembly groove 22 and is perpendicular to the assembly groove 22. The outer end of the loading trough 23 is connected to the conveying track of the fourth feeding assembly 21. The main rods 71 ​​can be fed into the loading trough 23 one by one along the conveying track through the vibration plate, and then into the assembly groove 22. Figure 5 As shown, when the loading push rod 221 is extended, the loading push rod 221 is provided with a positioning notch 2411, and the end thereof is basically located at the inner end of the assembly groove 22. At this time, the position of the grabbing notch 2211 is the assembly position 2b. At this time, the assembly position 2b is provided with a positioning groove 24 connected to the assembly groove 22 and perpendicular to the assembly groove 22. A positioning push rod 241 is provided in the positioning groove 24, and a cylinder for driving the positioning push rod 241 to move is provided at the outer end of the positioning groove 24. The end of the positioning push rod 241 is provided with a positioning notch 2411 that is adapted to the shape of the main rod 71.

[0078] When the assembly slot 22 in this patent is working, the fourth feeding assembly 21 first feeds the main rod 71 into the loading slot 23. At this time, the grabbing notch 2211 on the loading push rod 221 is opposite to the loading slot 23. During operation, the fourth feeding assembly 21 feeds the loading push rod 221 into the grabbing notch 2211 of the loading push rod 221. In this embodiment, the size of the loading push rod 221 is adapted to the assembly slot 22. When the main rod 71 is present in the grabbing notch 2211, the loading push rod 221 is actuated and moves toward the assembly position 2b, and at the same time drives the main rod 71 located in the grabbing notch 2211 to move along the assembly slot 22. At this time, the grabbing notch 2211 is no longer opposite to the loading slot 23, but the remaining main rods 71 ​​are restricted in the loading slot 23 by the rod body of the loading push rod 221. Driven by the loading push rod 221, the main rod 71 located in the grabbing notch 2211 is driven to the assembly position 2b. At this time, the main rod 71 in the grabbing notch 2211 is opposite to the positioning groove 24, and the positioning push rod 241 in the positioning groove 24 accordingly moves against the main rod 71 located in the grabbing notch 2211 to realize the positioning of the main rod 71. At this time, the assembly of the remaining components in the moving contact 7 can be carried out.

[0079] To sum up, this patent realizes the one-by-one transportation of the main rods 71 ​​through the structure of the assembly groove 22 and the loading push rod 221, and at the same time, the main rod 71 located in the assembly groove 22 is positioned by the positioning push rod 241, realizing the integration of one-by-one transportation and positioning, reducing the number of components of the overall assembly equipment and streamlining the overall structure of the equipment.

[0080] Furthermore, after the main rod 71 is loaded, the lower spring 72 in this patent is installed through the third assembly device 5.

[0081] like Figure 1 、 7 As shown, the third assembly device 5 includes a third feeding assembly 51 for conveying the lower spring 72 , a dividing seat 52 arranged on the frame 1 , a dividing block 53 arranged in the dividing seat 52 , and a spring push rod 54 .

[0082] Specific as Figure 7As shown, the material distribution seat 52 is connected to a suspension 56 that suspends it on the frame 1. The material distribution seat 52 is driven by a fifth driving member 521 to move forward and backward or up and down. It specifically includes a transverse slide assembly 5211 provided on the suspension 56 and a vertical slide assembly 5212 driven by the transverse slide assembly 5211, and the material distribution seat 52 is driven to move by the vertical slide assembly 5212. In this embodiment, the transverse slide assembly 5211 in the fifth driving member 521 is located directly above the assembly seat 2, and the material distribution seat 52 can be driven by the transverse slide assembly 5211 to move toward the extension direction of the assembly groove 22, while the vertical slide assembly 5212 can drive the material distribution seat 52 up and down close to the assembly seat 2 to achieve assembly.

[0083] like Figure 7 、 8 As shown, the material distribution seat 52 is hollow and is provided with a material distribution inlet 522 and a material distribution outlet 523. The material distribution inlet 522 is provided at the rear end of the material distribution seat 52 and is vertically upward. The material distribution inlet 522 is also connected to a guide frame through a sleeve. A guide channel 571 is provided in the guide frame, which is connected to the third feeding assembly 51 through the guide channel 571. The third feeding assembly 51 is actually a vibrating plate, which feeds the lower springs 72 one by one through the guide frame into the material distribution inlet 522. The material distribution outlet 523 is vertically provided at the front end of the material distribution seat 52 and is downwardly provided to be opposite to the assembly seat 2. The dividing block 53 is movably arranged in the hollow inner cavity of the dividing seat 52, and is communicated with the dividing inlet 522 and the dividing outlet 523. A cylinder is provided on the dividing seat 52 to drive the dividing block 53 to move; a vertical zero-time storage chamber 531 is provided in the dividing block 53, and the zero-time storage chamber 531 is cylindrical as a whole, which is used to adapt to the shape and length of the lower spring 72 and to accommodate a lower spring 72. Driven by the dividing block 53, the zero-time storage chamber 531 can be opposite to the dividing inlet 522 or the dividing outlet 523.

[0084] In this embodiment, the length of the zero-time storage chamber 531 is equivalent to the length of a single lower spring 72, so that only the first lower spring 72 can be placed in the single zero-time storage chamber 531, so as to achieve one-by-one material distribution. Figure 8As shown, when the cylinder driving the distribution block 53 to move is retracted, the upper end of the zero-time storage chamber 531 on the discharge block is opposite to the distribution inlet 522. At this time, the lower spring 72 can fall into the zero-time storage chamber 531 under the action of the third feeding component 51 and gravity, and at the same time, the lower spring 72 located in the zero-time storage chamber 531 is used to prevent the lower spring 72 from continuing to fall; when the cylinder driving the distribution block 53 to move is extended, the lower end of the zero-time storage chamber 531 on the discharge block is opposite to the distribution outlet 523, and the lower spring 72 located in the zero-time storage chamber 531 can be fed out from the distribution outlet 523, while the distribution inlet 522 is still limited by the distribution block 53, thereby realizing distribution one by one.

[0085] In combination with the fifth driving member 521 described in this patent, when the lower spring 72 is loaded, the lower spring 72 is sent into the zero-time storage chamber 531 from the distribution inlet 522, and then the fifth driving member 521 drives the entire distribution seat 52 to be located above the assembly seat 2, and the distribution outlet 523 is opposite to the main rod 71 located in the assembly seat 2. When the zero-time storage chamber 531 moves to be opposite to the distribution outlet 523, the lower spring 72 can be separated from the zero-time storage chamber 531 under the action of gravity, and pass through the distribution outlet 523 and be sleeved on the main rod 71.

[0086] Furthermore, the present invention also provides a spring push rod 54, which is used to push out the lower spring 72 located in the zero-time storage chamber 531 when the zero-time storage chamber 531 is opposite to the material distribution outlet 523; Figure 7 、 8 The spring push rod 54 is disposed above the material dispensing seat 52 and faces downward toward the material dispensing outlet 523. The material dispensing seat 52 also has a push rod inlet 541 opposite to the spring push rod 54. When the lower end of the zero-hour storage chamber 531 faces the material dispensing outlet 523, the zero-hour storage chamber 531 is located between the material dispensing outlet 523 and the push rod inlet 541. When the material dispensing outlet 523 is located above the assembly seat 2, the spring push rod 54 operates to push out the lower spring 72, preventing the lower spring 72 from getting stuck in the zero-hour storage chamber 531.

[0087] Furthermore, the distribution outlet 523 is further connected to a guide sleeve 55; Figure 7 As shown, the guide sleeve 55 is cylindrical and is fixed to the lower end of the material distribution outlet 523. It is used to guide the falling direction of the lower spring 72 when the lower spring 72 falls, and prevent the lower spring 72 from deviating during its falling process and affecting the installation of the lower spring 72.

[0088] In summary, the third assembly device 5 in this patent realizes the loading of the lower springs 72 one by one through the material distribution seat 52, thereby achieving stable and accurate installation of the lower springs 72.

[0089] Furthermore, after the lower spring 72 is installed, the present invention installs the movable contact piece 73 via the second assembly device 4. In this patent, the center of the movable contact piece 73 is provided with a connection hole 731 for connecting to the main rod 71, and stamping grooves 732 are formed at both ends of the movable contact piece 73. The stamping grooves 732 are used to make the front side of the movable contact piece 73 convex and the back side concave inward. The second assembly device 4 is provided on one side of the assembly base 2 and specifically includes a third drive member 41, an assembly fixture 42, and a contact piece feed assembly 43.

[0090] like Figure 12 As shown, the third driving member 41 includes a front and rear slide rail assembly 412 arranged on the frame 1 and a lifting slide rail assembly 411 arranged on the front and rear slide rail assembly 412 and driven thereby. The front and rear slide rail assembly 412 and the lifting slide rail assembly 411 are both driven by cylinders, and the assembly fixture 42 is arranged on the lifting slide rail assembly 411, and the front and rear slide rail assembly 412 and the lifting slide rail assembly 411 are used to realize the front and rear movement or lifting movement of the assembly fixture 42.

[0091] Combine Figure 13 、 14 As shown in Figures 15 and 15, the movable contact piece 73 in this patent is flat, and accordingly the assembly fixture 42 is formed by clamping two upper and lower clamping plates 426. A flat clamping cavity 421 adapted to the shape of the movable contact piece 73 is formed between the two clamping plates 426, and the front ends and sides of the two clamping plates 426 are open to form an assembly inlet 422 located on the side of the assembly fixture 42, and an assembly outlet 423 located on the front end of the assembly fixture 42.

[0092] The contact piece feeding assembly 43 is arranged on the side of the assembly fixture 42 provided with the assembly inlet 422, and is connected to the second feeding assembly 431 for conveying the movable contact piece 73. The contact piece feeding assembly 43 is used to feed the contact pieces one by one from the assembly inlet 422 into the clamping cavity 421. Specifically, the contact piece feeding assembly 43 includes a feeding fixture 432, a fourth driving member 433 and a detection head 434, as shown in FIG. Figure 13 、 14As shown, the feeding fixture 432 is composed of a base 4325 and a sealing plate 4324 covering the base 4325, so that an accommodating space for accommodating a single movable contact piece 73 is formed between the sealing plate 4324 and the base 4325; the sealing plate 4324 is square, and after the sealing plate 4324 is set on the base 4325, a push port 4326, a contact piece outlet 4322 and a contact piece inlet 4321 are formed between the sealing plate 4324 and the base 4325, which are respectively arranged in three directions of the square sealing plate 4324, and the contact piece outlet 4322 is opposite to the assembly fixture 42, and a fourth driving member 433 is provided on the frame 1 outside the pushing port 4326, and the contact piece inlet 4321 is connected to the outside of the conveying track, and is connected to the second feeding component 431 through the conveying track.

[0093] In this embodiment, the push port 4326 and the contact piece outlet 4322 are respectively disposed on the left and right sides of the feed fixture 432. The fourth driving member 433 is specifically a push rod driven by a pneumatic cylinder. During operation, the movable contact piece 73 is fed into the feed fixture 432 by the second feeding assembly 431 and positioned between the push port 4326 and the contact piece outlet 4322. The fourth driving member 433 then pushes the movable contact piece 73 within the feed fixture 432, causing the movable contact piece 73 to be ejected from the contact piece outlet 4322 and enter the assembly fixture 42 through the assembly inlet 422 of the assembly fixture 42, thereby loading the movable contact piece 73. Until the movable contact piece 73 in the assembly fixture 42 is assembled on the main rod 71 by the assembly fixture 42, the contact piece feeding assembly 43 continues to work to convey the movable contact piece 73 to the assembly fixture 42, thereby realizing the one-by-one loading of the movable contact pieces 73 through the contact piece feeding assembly 43.

[0094] Furthermore, the contact sheet feeding assembly 43 further includes a detection head 434, which is arranged outside the feeding fixture 432, and the feeding fixture 432 is provided with a detection hole 4323 corresponding to the detection head 434. Figure 12 As shown, the detection head 434 is fixed to one side of the feed fixture 432 via a bracket. The detection hole 4323 is formed in the cover plate 4324 of the feed fixture 432, and the bracket is used to align the detection hole 4323 with the detection head 434. After the movable contact piece 73 is fed into the feed fixture 432, the front protrusion formed by the punched groove 732 on the movable contact piece 73 is located within the detection hole 4323. The detection head 434 detects the height of the front protrusion and provides feedback through readings to determine whether the dimensions of the punched groove 732 in the movable contact piece 73 are met.

[0095] After the loading of the movable contact piece 73 is completed, the movable contact piece 73 is assembled in the assembly fixture 42. By connecting the assembled third driving member 41, the entire assembly fixture 42 is driven to perform the ascending action, the advancing action, the descending action, and the retreating action in sequence, so that the movable contact piece 73 is completely sheathed outside the main rod 71 to achieve assembly. To achieve assembly, the assembly fixture 42 is further provided with a disengagement slot 424 at the top and bottom. The disengagement slot 424 has a disengagement port toward the front end of the assembly fixture 42. Figure 13 、 14 As shown, the disengagement slot 424 is a U-shaped slot provided on the upper and lower clamping plates 426 of the assembly fixture 42. The bottom of the U-shaped slot is opposite to the connection hole 731 of the movable contact piece 73, and the opening direction of the U-shaped slot is the same as the forward movement direction of the assembly fixture 42. When the assembly fixture 42 moves in sequence to complete the ascending, advancing, and descending movements, the entire movable contact piece 73 is driven by the assembly fixture 42, so that the main rod 71 located on the assembly seat 2 passes through the U-shaped slot and is inserted into the connection hole 731 of the movable contact piece 73. Then, when the assembly fixture 42 completes the retreating movement, the movable contact piece 73 is disengaged from the assembly fixture 42 through the assembly outlet 423 of the assembly fixture 42, and the installation of the movable contact piece 73 is completed.

[0096] In summary, this patent drives the assembly fixture 42 to move the moving contact piece 73 from top to bottom through the third driving member 41 to realize the assembly of the moving contact piece 73, realize the transportation and assembly of flat objects, and realize the full automation of the installation of the moving contact piece 73.

[0097] Furthermore, the assembly fixture 42 is provided with a positioning protrusion 425, which is used to correspond to the working groove on the movable contact piece 73. Figure 14 As shown, the positioning protrusion 425 includes a steel ball arranged on the lower side clamping plate 426 of the assembly fixture 42. The steel ball is embedded in the lower side clamping plate 426 and its position is opposite to the stamping groove 732 so that when the movable contact piece 73 is sent into the assembly fixture 42, the steel ball is inserted into the stamping groove 732 to achieve positioning.

[0098] After the moving contact piece 73 is installed, the clamping spring 74 is installed by the first assembly device 3. Figure 9 As shown, the first assembly device 3 includes:

[0099] A first driving member 311 drives a feeding plate 312 , wherein the feeding plate 312 is provided with a feeding slot 313 adapted to the width of the clamping spring 74 ;

[0100] The second driving member 321 is provided on the first driving member 311 and is synchronously driven by the first driving member 311; the second driving member 321 drives a push plate 322 that slides in the feeding trough 313;

[0101] The feeding guide 33 is arranged above the feeding plate 312. A guide groove 331 is provided in the feeding guide 33. The inlet of the guide groove 331 is connected to a first feeding component 332 for conveying the retaining spring 74. A feeding gap adapted to the size of a single retaining spring 74 is formed between the outlet of the guide groove 331 and the feeding plate 312.

[0102] Specific as Figure 9 、 10 As shown, the first driving member 311 is a slide rail assembly arranged on the frame 1 and driven by a cylinder. The feed plate 312 is driven by a slide plate in the slide rail assembly. Two limit blocks are also fixed on both sides of the surface of the feed plate 312, and the feed trough 313 is formed between the two limit blocks.

[0103] The second driving member 321 is a cylinder fixed to the slide rail assembly. A push plate 322 is connected to the driving end of the cylinder. The push plate 322 is flat and has a thickness substantially the same as that of the retaining spring 74. Driven by the second driving member 321, the push plate 322 slides along the surface of the feed trough 313. The push plate 322 pushes the retaining spring 74 located on the surface of the feed trough 313, causing the retaining spring 74 to move along the feed trough 313, which is adapted to the width of the feed trough 313.

[0104] The loading guide 33 is vertically arranged above the feeding trough 313, and includes a vertically arranged guide plate 334. The guide plate 334 is connected to a guide support frame by screws. The lower end of the guide support frame is fixed on the frame 1, and is used to suspend the guide plate 334 above the feeding plate 312. A concave surface 3341 is provided on one side surface of the guide plate 334, and a guide profile 336 is provided in the concave surface 3341. The cross-section of the guide profile 336 is T-shaped, and the tail of the T-shape is connected to the concave surface 3341, so that a guide groove 331 in the shape of an adaptive retaining spring 74 is formed between the guide profile 336 and the concave surface 3341. The upper end of the guide groove 331 is an inlet, and the upper and lower ends of the guide groove 331 are outlets. In this embodiment, the retaining spring 74 is annular, and engaging protrusions are provided on both sides of the annular retaining spring 74. The engaging protrusions are used to be engaged on both side surfaces of the guide profile 336, such as Figure 11 As shown, the clamping spring 74 can slide down along the guide profile 336 to guide the clamping movement.

[0105] In this patent, the upper end of the guide plate 334 is connected to the first feeding assembly 332. The first feeding assembly 332 is specifically a vibration plate arranged on the frame 1. The vibration plate is connected to a conveying pipe for conveying the retaining spring 74. The retaining spring 74 is sequentially conveyed into the guide groove 331 of the guide plate 334 through the conveying pipe through the vibration plate. Since the guide plate 334 is vertically suspended above the feed trough 313 by the guide plate support frame 335, a feeding gap is formed between the lower end of the guide plate 334 and the feed trough 313. The size of the feeding gap is adapted to the thickness of a single retaining spring 74, so that when the retaining spring 74 is fed into and falls along the guide plate 334 to the feed trough 313, the feed plate 312 works to push the retaining spring 74 located between the feeding gaps; before the feed plate 312 is pushed, the first driving member 311 works to make the entire feed plate 312 close to the assembly seat 2, and then the feed plate 312 works to push the retaining spring 74 so that the retaining spring 74 is directly retained on the main rod 71 to achieve assembly. During the pushing process of the feeding plate 312, since the feeding gap can only accommodate a single retaining spring 74, the remaining retaining springs 74 will be limited by the feeding plate 312 above the feeding gap until the feeding plate 312 is reset, and the retaining springs 74 fall down to facilitate the next assembly. Therefore, the present invention realizes the assembly of the retaining springs 74 through the feeding plate 312 structure, and realizes the unloading of the retaining springs 74 one by one through the feeding guide 33 and the feeding plate 312. The overall result is compact, effectively reducing the volume of the equipment.

[0106] Furthermore, the guide plate 334 is further provided with a guide cover 337 that closes the guide groove 331. The lower end of the guide cover 337 is provided with a guide portion 3371 located in the feed groove 313. A guide gap is formed between the guide portion 3371 and the feed plate 312. Figure 11 As shown, the guide cover 337 is fixed to the lower end of the guide plate 334, that is, the end of the guide plate 334 with the discharge port. The guide portion 3371 extends into the feed trough 313, and the end of the guide portion 3371 is close to the feed trough 313, thereby forming the guide gap. The guide cover 337 closes the guide groove 331 to sequentially limit the position of the retaining spring 74 about to enter the feeding gap, preventing the retaining spring 74 from falling out of the guide groove 331 due to the push of the feed plate 312. At the same time, the movement of the feed plate 312 is guided in advance by the guide gap.

[0107] After the retaining spring 74 is installed, the upper spring 75 is installed using the third assembly device 5. The installation process for the upper spring 75 is the same as that for the lower spring 72. After the upper spring 75 is installed, the assembled movable contact 7 is delivered by the unloading device 6. The unloading device 6 includes an unloading robot 61 and an unloading conveyor 62. The unloading robot 61 clamps the movable contact 7 located in the assembly seat 2 and then transports it to the unloading conveyor 62 for unloading. During the clamping process, the positioning push rod 241 and the loading push rod 221 are simultaneously reset to facilitate the unloading of the movable contact 7.

[0108] The above embodiments are only preferred embodiments of this patent and are not intended to limit the scope of protection of this patent. Therefore, any equivalent changes made based on the structure, shape, and principle of this patent should be covered within the scope of protection of this patent.
