The turntable assembly drives the housing positioning fixture to pass through each station for precise positioning. The housing loading / unloading assembly, through the installation of a material tray conveyor line, a housing flipping assembly, and a clamping loading / unloading assembly, achieves automatic conveying and flipping of the housings, and transports the housings from the material tray to the housing positioning fixture of the turntable assembly for loading and positioning.

Finally, the carbon brush assembly assembly removes the carbon brushes from the wire straightening assembly and automatically assembles them into the housing, completing the carbon brush assembly. The pre-assembled carbon brushes are then transported to the wire pulling assembly to automatically straighten the lead wires at the bottom of the carbon brushes. Next, the lead wire welding clamping assembly welds the lead wires to the pins of the housing. Then, the carbon brush pressure detection assembly presses down on the carbon brush to detect the rebound force, thereby detecting the assembly effect of the carbon brush. After the detection is completed, the wire cutting assembly cuts off the remaining lead wires outside the solder joint and collects the waste material. The carbon brush vision inspection assembly inspects the quality of the solder joints. Finally, the assembled housing returns to the housing loading and unloading assembly station for automatic housing unloading. The entire assembly process requires no manual intervention, realizing automated carbon brush assembly, greatly improving assembly efficiency and quality, and ensuring the pass rate of carbon brush assembly.

[0045] refer to Figure 1 , Figure 4 and Figure 5 Specifically, the turntable assembly 2 includes a rotating disk 21 rotatably connected to the base 1 in the horizontal direction and several housing positioning fixtures 22 evenly spaced and fixedly connected to the rotating disk 21 in the circumferential direction for housing positioning. A rotary motor for driving the rotating disk 21 to rotate is fixedly connected to the base 1. The housing positioning fixture 22 has slot positioning holes 23. Positioning cylinders 24 are fixedly fixed at several stations in the circumferential direction of the base 1. Positioning blocks 25 for inserting into the slot positioning holes 23 to position the housing positioning fixture 22 are fixedly connected to the telescopic end of the positioning cylinders 24. The turntable assembly 2 drives the rotating disk 21 to rotate through the rotary motor, so that the housing positioning fixture 22 passes through each station in sequence. When assembling, in order to ensure the assembly accuracy, the positioning cylinders 24 drive the positioning blocks 25 to insert into the slot positioning holes 23, thereby achieving precise positioning and fixing of the housing positioning fixture 22 at each station, improving the accuracy of carbon brush assembly and the reliability of the assembly process.

[0046] refer to Figures 1 to 3Specifically, the shell loading / unloading assembly 3 includes a tray conveyor line 31 fixedly connected horizontally to the base 1 for conveying trays, and a shell flipping assembly 32 for flipping shells on the tray. A clamping loading / unloading assembly 33 is also fixedly connected to the base 1 for clamping the assembled shells from the shell positioning fixture 22 located at the loading / unloading station into the tray for unloading, and for clamping the shells from the tray into the shell positioning fixture 22 located at the loading station for loading and positioning. The tray is conveyed on the tray conveyor line 31. The tray conveyor line 31 is located at the shell flipping station where the shell flipping assembly 32 is located. The loading and unloading station of the housing, where the clamping and unloading assembly 33 is located, is also equipped with a blocking cylinder to position the material tray; the housing tilting assembly 32 includes a tilting seat 321 fixedly connected to the base 1, a tilting horizontal sliding cylinder 322 fixedly connected to the tilting seat 321 in the horizontal direction, and a tilting vertical lifting cylinder 323 fixedly connected to the extension end of the tilting horizontal sliding cylinder 322 in the vertical direction. A tilting vertical adjustment cylinder 324 is fixedly connected to the lifting end of the tilting vertical lifting cylinder 323, and a tilting horizontal adjustment cylinder is fixedly connected to the tilting vertical adjustment cylinder 324 in the horizontal direction. 325. A first rotary clamping cylinder 326, arranged horizontally, is fixedly connected to the telescopic end of the tilting horizontal adjustment cylinder 325. A first housing clamping block 327 for clamping the housing is fixedly connected to the clamping end of the first rotary clamping cylinder 326. The tilting vertical lifting cylinder 323 and the tilting vertical adjustment cylinder 324 drive the first rotary clamping cylinder 326 to achieve lifting and lowering, and the tilting horizontal adjustment cylinder 325 drives the first rotary clamping cylinder 326 to achieve horizontal movement. The first rotary clamping cylinder 326 drives the first housing clamping block 327 to clamp the housing, thereby causing the housing to tilt from a horizontal state. The housing is positioned vertically so that the carbon brush mounting holes on the housing face upwards. The clamping and unloading assembly 33 includes a loading and unloading screw slide 331 fixedly connected to the base 1 in the horizontal direction and a set of lifting and picking cylinders 332 fixedly connected in parallel to the sliding end of the loading and unloading screw slide 331.

A second housing clamping block 334 is fixedly connected to the clamping end of the housing clamping cylinder 333. The loading and unloading screw slide 331 drives the housing clamping cylinder 333 to move back and forth between the turntable assembly 2 and the loading station, thereby realizing the loading and unloading of the housing.

[0047] refer to Figure 6 and Figure 7Specifically, the spring feeding and conveying assembly 4 includes a conveying fixed base 41 fixedly connected to the base 1 and a conveying lifting cylinder 42 fixedly connected to the conveying fixed base 41 in a vertical direction. A conveying lifting seat 43 arranged in a horizontal direction is fixedly connected to the telescopic end of the conveying lifting cylinder 42. A spring feeding pipe 44 arranged in a vertical direction is adjustablely fixedly connected to the bottom of the conveying lifting seat 43 for the spring to pass through and enter the housing. The spring feeding pipe 44 is externally connected to a spring conveying pipe to realize the spring feeding. The spring conveying pipe is connected to a spring vibrating feeding plate to realize the spring feeding. A clamping and blocking cylinder 45 arranged in a horizontal direction is fixedly connected to the conveying lifting seat 43. A blocking rod 46 that penetrates from the side into the spring feeding pipe 44 to block the spring from passing through is fixedly connected to the clamping end of the clamping and blocking cylinder 45. A laser sensor 47 for detecting the spring feeding status in the spring feeding pipe 44 is also fixedly fixed to the conveying lifting seat 43. The side wall of tube 44 is provided with a blocking hole 48 for the blocking rod 46 to pass through and a detection hole 49 for the laser to pass through. The spring is transported from the spring feeding tube 44 to the carbon brush mounting hole in the housing. When spring feeding is not required, the clamping and blocking cylinder 45 drives the blocking rod 46 to pass into the spring feeding tube 44 to prevent the spring from passing through. When spring assembly is required, the transport lifting cylinder 42 drives the transport lifting seat 43 to descend, so that the spring feeding tube 44 is lowered to directly above the carbon brush mounting hole in the housing. Then, the laser sensor 47 detects whether there is a spring in the spring feeding tube 44. If there is a spring, the clamping and blocking cylinder 45 opens to make the blocking rod 46 disengage from the spring feeding tube 44, so that the spring enters the carbon brush mounting hole. Then, the clamping and blocking cylinder 45 continues to drive the blocking rod 46 to pass into the spring feeding tube 44 to prevent the spring from passing through, thereby ensuring the accuracy of the number of springs fed in at one time and avoiding the error of manual feeding. Based on this, the automatic transport and assembly of springs is realized.

[0048] refer to Figure 8 Specifically, the carbon brush feeding assembly 5 includes a hopper assembly 51 for storing carbon brushes, which is fixedly connected to the base 1, and a straightening assembly 52 for straightening the carbon brush leads.

A carbon brush assembly assembly 54 for assembling the straightened carbon brushes into the housing is also fixedly connected to the base 1. The carbon brush feeding assembly 5 stores carbon brushes by setting the hopper assembly 51 and transports multiple carbon brushes from the hopper assembly 51 to the straightening assembly 52 for positioning by setting the carbon brush transport assembly 53. The straightening assembly 52 straightens the leads at the bottom of the positioned carbon brushes. Finally, the carbon brush assembly assembly 54 removes the carbon brushes from the straightening assembly 52 and automatically assembles them into the housing to complete the carbon brush assembly.

[0049] refer to Figure 9 and Figure 10 Specifically, the hopper assembly 51 includes an empty hopper 511 for storing empty carbon brush trays and a storage hopper 512 for storing carbon brush trays, both fixedly connected in parallel to the base 1. A sliding drawer seat 513 for storing carbon brush trays is slidably disposed within the empty hopper 511 and the storage hopper 512. A tray positioning seat 514 for positioning stacked carbon brush trays is vertically disposed on the sliding drawer seat 513. The tray positioning seat 514 positions the four right-angled sides of the carbon brush tray, thus achieving the positioning of the carbon brush tray. The carbon brush tray containing carbon brushes is placed into the storage hopper 51 by pulling out the sliding drawer seat 513. 2. The empty material tray in the empty material bin 511 is removed. A through hole 515 is provided on the sliding drawer seat 513 for the carbon brush tray to pass through. Rotating blocks 516 are rotatably connected to both sides of the through hole 515 in the empty material bin 511 and the storage bin 512. Triangular blocking blocks 517 for blocking and supporting the carbon brush tray are fixedly connected to the rotating blocks 516. In the initial state, the rotating blocks 516 are drooping, and the upper surface of the right-angled side of the triangular blocking block 517 is in a horizontal state, thereby supporting both sides of the carbon brush tray and preventing the stacked carbon brush tray from falling. The empty material bin 511 and the storage bin 512 are based on the unlocking cylinder 518. A vertically movable unlocking pressing block 519 is connected to the rotating block 516 to cause the triangular blocking block 517 to tilt, thus allowing the carbon brush tray to pass through. When the carbon brush tray needs to be loaded or unloaded, the unlocking cylinder 518 drives the unlocking pressing block 519 to press the top of the rotating block 516, causing the rotating block 516 to rotate and tilt. At this time, the upper surface of the right-angled side of the triangular blocking block 517 disengages from the carbon brush tray, and the hypotenuse of the triangular blocking block 517 rotates to the vertical plane. At this time, the carbon brush tray can automatically pass through the through hole 515 to achieve loading and unloading. Through the cooperation of the rotating block 516 and the triangular blocking block 517, the carbon brush tray can be loaded and unloaded. The automatic support and locking of the brush disc ensures that the rotating block 516 can automatically droop. The center of gravity of the rotating block 516 is lower. A vertically arranged horizontal lead screw slide 5110 is fixedly connected to the base 1. A vertically arranged vertical lead screw slide 5111 is fixedly connected to the sliding end of the horizontal lead screw slide 5110.

A positioning clamping cylinder 524 is fixedly connected to the horizontal winding base 521 for pushing the carbon brush sliding positioning block 522 to slide. The two sets of positioning clamping cylinders 524 respectively drive... The corresponding carbon brush sliding positioning block 522 slides to clamp and fix the carbon brush, which is positioned in the carbon brush positioning groove 523. Sensors for detecting carbon brushes are symmetrically arranged on both sides of the horizontal winding seat 521 located in the carbon brush positioning groove 523 to detect whether a carbon brush exists in the carbon brush positioning groove 523. A horizontal winding screw slide 525 is fixedly connected to the horizontal winding seat 521, and a winding screw arranged vertically is fixedly connected to the sliding end of the horizontal winding screw slide 525.

[0057] Brief description of the usage process: First, the shell loading and unloading assembly 3 starts, and the material tray conveyor line 31 transports the material tray carrying the shell to the designated position. The clamping loading and unloading assembly 33 drives the second shell clamping block 334 through the loading and unloading screw slide 331 and the lifting and picking cylinder 332 to clamp the shell in the material tray into the shell positioning fixture 22 of the turntable assembly 2 to complete the loading. The rotary motor of the turntable assembly 2 drives the turntable 21 to rotate, and the shell positioning fixture 22 is transferred to the next station. The positioning cylinder 24 drives the positioning block 25 to insert into the slot positioning hole 23 to ensure that the shell positioning fixture 22 is accurately fixed.

[0058] Next, the spring feeding and conveying assembly 4 operates. The spring is conveyed through the spring feeding tube 44. After the laser sensor 47 confirms the incoming material status through the detection hole 49, the clamping and blocking cylinder 45 drives the blocking rod 46 to retract. The conveying and lifting cylinder 42 drives the spring feeding tube 44 to descend. The spring falls into the carbon brush mounting hole in the housing. Then the blocking rod 46 resets to block subsequent springs, completing the spring feeding.

The wire straightening screw slide of the wire straightening assembly 52 drives the second rotary clamping cylinder 527 to move. The first V-shaped clamping groove clamps the wire and rotates to straighten it. Finally, the carbon brush assembly assembly 54, through the assembly clamping block 546 and the rotary jaw clamping cylinder 547, assembles the carbon brush and wire into the housing.

[0060] Subsequently, the clamping lifting cylinder 63 of the wire pulling assembly 6 drives the wire clamping claw 64 to clamp the wire, and the wire pulling cylinder 62 drives it to descend and straighten the wire in preparation for welding. The turntable sends the workpiece to the wire clamping and welding assembly 7. The welding horizontal screw adjusting slide 72, welding adjusting cylinder 73 and other components adjust the welding position. The first and second resistance welding heads 79 cooperate to complete the resistance welding of the wire and the lead. Then, the pre-pressure cylinder 82 of the carbon brush pressure detection assembly 8 pre-pressures the carbon brush, and the vertical screw detection slide 84 drives the pressure detection head 87 to press down. The pressure sensor 88 detects the rebound force, screens out products that do not meet the elasticity standard and marks them.
