DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The invention discloses an indoor vacuum circuit breaker assembly line, which mainly assembles indoor vacuum circuit breakers and parts thereon, and automatically loads and unloads materials. Indoor vacuum circuit breakers are a type of electric switch. Automatically assembling indoor vacuum circuit breakers reduces assembly costs and helps to improve production and assembly efficiency.

[0025] like Figure 1 , Figure 2 As shown, the indoor vacuum circuit breaker includes a base 1, on which a circuit breaker body 11 is fixedly provided, on which an array-distributed insulating sleeve 13 is fixedly connected, and on which a circuit breaker housing 12 is fixedly provided, and the circuit breaker housing 12 is fixedly connected to the bottom of the insulating sleeve 13, and is connected to the insulating sleeve 13 by passing bolts through the circuit breaker housing 12.

[0026] A support tube is fixedly provided on the insulating sleeve 13 . Due to the existence of the support tube, it is inconvenient to assemble and clamp during actual installation, which affects the assembly accuracy of the circuit breaker housing 12 and the insulating sleeve 13 .

[0027] like Figure 3 As shown, the assembly line includes a bracket 2 , on which a top plate 3 is fixedly mounted, on which a material moving component 4 is fixedly mounted, and on the top of the bracket 2 , an assembly component 5 is fixedly mounted, and the assembly component 5 is located on one side of the top plate 3 .

[0028] In this embodiment, the bracket 2 serves as the main body of the assembly line, and the top plate 3 is used to control the installation of a driving component for controlling the movement of the material moving component 4 to translate the material moving component 4 to move multiple insulating sleeves 13. The material moving component 4 clamps multiple insulating sleeves 13 in batches, thereby reducing the number of loading and unloading times and improving the efficiency of automatic loading.

[0029] The automatic screw driving structure on the assembly component 5 is used to automatically drive the screws used to connect the circuit breaker housing 12 and the insulating sleeve 13 into the insulating sleeve 13, and the assembly is automatically assembled, and then the assembly test is performed. The test operation uses multiple swing rods 502 to move back and forth alternately to impact the circuit breaker body 11, so that the circuit breaker body 11 vibrates, simulating a reasonable vibration condition during the actual use of electrical equipment, so as to detect the firmness of the assembly of the insulating sleeve 13 and the circuit breaker body 11.

[0030] If the connection between the circuit breaker housing 12 and the insulating sleeve 13 is loose, the screws can be reinforced to improve the connection firmness between the circuit breaker housing 12 and the insulating sleeve 13. If reinforcement is not possible, defective products are rejected, which helps to reduce the assembly strength of subsequent assembly processes, simplify the assembly process of defective products, and reduce assembly costs.

The output end of cylinder 2 46 is telescopically moved to control the rotation of the swing arm 461, so that the moving rod 44 is translated on the cross groove 42, and the moving rod 44 moves horizontally along the direction of the cross groove 42.

[0036] Side plates 47 are fixedly provided on both sides of the material moving assembly 4 . Guide grooves 48 are provided on the side plates 47 . The guide grooves 48 are slidably connected to the cross bars 45 located on both sides of the material moving assembly 4 . The cross bars 45 are guided and supported by the guide grooves 48 .

[0037] The bottom of the material moving assembly 4 is fixedly provided with pneumatic clamps 49 distributed in an array. The pneumatic clamps 49 are arranged corresponding to the vertical grooves 41 and are used to clamp the insulating sleeve 13 to facilitate the movement of the insulating sleeve 13.

[0039] A cylinder three 404 is fixedly installed on the fixture 40, and a pressure plate 405 is fixedly connected to the output end of the cylinder three 404. A V-shaped block 406 is fixedly provided at the bottom of the fixture 40. Through grooves 407 are opened on both sides of the V-shaped block 406. A support plate 408 is slidably provided in the through groove 407. A spring two 409 is fixedly connected to the bottom of the support plate 408. The spring two 409 is fixedly connected to the bottom of the V-shaped block 406 to lift the support plate 408 so that the support plate 408 supports the support tube of the insulating sleeve 13.

[0040] The output end of the pneumatic clamp 49 is used to push the pressure plate 405 to press down the insulating sleeve 13. The pressure plate 405 and the support plate 408 clamp and fix the support tube of the insulating sleeve 13. The V-shaped block 406 limits the two sides of the support tube to lock the direction of the insulating sleeve 13, making it easier for the pneumatic clamp 49 to lock and fix the insulating sleeve 13.

[0041] like Fig.10 , Fig.11 , Fig.12 As shown, the assembly component 5 includes a connecting block 51, which is fixed on the top frame 21 and is threadedly connected to the top frame 21 by bolts passing through the connecting block 51 to lock the assembly component 5. A cylinder four 52 is fixedly provided on the connecting block 51, and a movable plate 53 is fixedly connected to the output end of the cylinder four 52. A motor seat 55 is fixedly installed on the movable plate 53. A motor one 56 is fixedly provided in the motor seat 55, and a screwdriver 57 is fixedly connected to the output end of the motor one 56. The screwdriver 57 is driven to rotate by the motor one 56, and the screw is quickly passed through the circuit breaker housing 12 and threadedly connected to the insulating sleeve 13, thereby completing the assembly and fixation of the insulating sleeve 13.

[0042] Positioning blocks 54 are fixedly provided on both sides of the movable plate 53, and the positioning blocks 54 are connected to the positioning holes 26. When the cylinder 52 pushes the movable plate 53 to move vertically, the positioning blocks 54 cooperate with the positioning holes 26, and the movable plate 53 is positioned and fixed on the top of the mounting frame 24, thereby improving the working accuracy and stability of the screwdriver 57 and improving the assembly accuracy of the indoor vacuum circuit breaker.

[0043] A vertical plate 58 is fixedly provided at one end of the movable plate 53, a motor 2 59 is fixedly provided at one side of the vertical plate 58, a cam 505 is fixedly connected to the output end of the motor 2 59, an array of through slots 500 are provided at one end of the vertical plate 58, a detection rod 50 is rotatably provided in the through slot 500, a detection block 501 is fixedly connected to one end of the detection rod 50, and a pendulum rod 502 is fixedly connected to the other end, the pendulum rod 502 is vertically connected to the detection rod 50, a spring 3 504 is fixedly provided between the pendulum rod 502 and the through slot 500, and the spring 3 504 is used to fix the pendulum rod 502 and the vertical plate 58.

[0044] An inclined surface 503 is fixedly provided at one end of the swing rod 502 away from the detection rod 50, and the inclined surface 503 is symmetrically arranged on the side of the swing rod 502 close to the vertical plate 58. When the cam 505 rotates, the cam 505 is slidably connected with the inclined surface 503, pushing the swing rod 502 to rotate in the direction away from the vertical plate 58, and the detection block 501 on the detection rod 50 rotates upward and gradually moves away from the circuit breaker body 11. When the cam 505 is separated from the swing rod 502, the spring three 504 applies a pulling force to the swing rod 502 to reset the swing rod 502, and the detection block 501 moves toward the circuit breaker body 11 and hits the circuit breaker body 11 to vibrate the circuit breaker body 11, so as to detect the firmness of the assembly of the insulating sleeve 13 and the circuit breaker body 11.

[0045] In this embodiment, the model of the slide 1 31 and the slide 2 32 are both TEB17D, and the model of the pneumatic clamp 1 27 and the pneumatic clamp 2 49 are both YMP20-25.

[0046] Here’s how it works: Indoor vacuum circuit breakers are large in size. They are currently fixed with assembly brackets, which makes manual assembly difficult, with low assembly efficiency and high labor costs. Assembly lines are used for assembly operations to improve the assembly efficiency of indoor vacuum circuit breakers, which is suitable for mass production. The specific assembly process is as follows: The produced insulating sleeves 13 are arranged in sequence on a conveyor belt 22, and the conveyor belt 22 feeds the insulating sleeves 13 so that the insulating sleeves 13 are transported to one side of the material transfer assembly 4. The slide 2 32 is moved by the slide 1 31 to move the slide 2 32 to one side of the conveyor belt 22, and then the slide 2 32 is used to control the material transfer assembly 4 to move toward the conveyor belt 22, and a pneumatic clamp 2 49 is moved toward the insulating sleeve 13 to clamp the insulating sleeve 13.

[0047] During this process, the V-shaped block 406 limits the two sides of the support tube, locks the direction of the insulating sleeve 13, and uses the output end of the pneumatic clamp 49 to push the pressure plate 405 to press down the insulating sleeve 13. The pressure plate 405 and the support plate 408 clamp and fix the support tube of the insulating sleeve 13 to fix the insulating sleeve 13.

[0048] By repeating this operation, the three insulating sleeves 13 are fixed to one side of the material moving component 4, and then the three insulating sleeves 13 are moved in batches using slide 2 32 and slide 1 31 to improve the material moving efficiency. The output end of cylinder 2 46 is telescopically moved to control the rotation of the swing arm 461, so that the moving rod 44 is translated on the transverse groove 42, and the moving rod 44 moves horizontally along the direction of the transverse groove 42. The driven shaft 403 slides on the upper inclined surface of the inclined rod 43 to adjust the height of the three insulating sleeves 13, keep the movement of the three insulating sleeves 13 synchronous, and improve the accuracy of material moving and loading.

[0049] Then, the pneumatic clamp 27 is moved by the pneumatic clamp 27 to splice and assemble the circuit breaker body 11 and the insulating sleeve 13 to be assembled. After the assembly is completed, the automatic screwing operation is performed. The positioning block 54 cooperates with the positioning hole 26, and the movable plate 53 is positioned and fixed on the top of the mounting frame 24, thereby improving the working stability of the screwdriver 57 and improving the assembly accuracy.

[0050] After the insulating sleeve 13 is fixed, the cam 505 is driven to rotate. When the cam 505 is separated from the swing rod 502, the spring three 504 applies a pulling force to the swing rod 502, so that the swing rod 502 is reset and moved. The detection block 501 moves toward the circuit breaker body 11 and hits the circuit breaker body 11 to make the circuit breaker body 11 vibrate, so as to detect the firmness of the assembly of the insulating sleeve 13 and the circuit breaker body 11.

[0051] Then, the pneumatic clamp 27 loosens the circuit breaker body 11, and uses a slide 31 to move the assembled indoor vacuum circuit breaker to another conveyor belt 22 to discharge the finished indoor vacuum circuit breaker and perform automated assembly operations.

[0052] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
