[0041] When the sliding rod 213 moves along the feeding groove 232, each feeding push plate 211 is inserted between two adjacent carbon brush holder assemblies 9 in sequence, and pushes each carbon brush holder assembly 9 to move forward.

[0042] When the sliding rod 213 moves along the reset groove 231, each feed push plate 211 is located below the feed track 22, and the feed frame 21 moves backward to prepare for the next push of the carbon brush holder assembly 9 forward.

[0043] When the sliding rod 213 moves along the connecting groove 233 , the feeding frame 21 only moves longitudinally, and the feeding push plate 211 enters or leaves the feeding track 22 .

[0044] When the rotating frame 24 rotates, the feed slide groove 241 will drive the sliding rod 213 to slide along the circular groove 230, and then the feed frame 21 moves synchronously. With the cyclic movement of the feed frame 21, the feed push plate 211 gradually pushes each carbon brush frame assembly 9 forward in an orderly manner.

[0045] The transfer station 3 also includes a reciprocating frame 32 rotatably connected to the fixed plate 31; the transfer frame 39 is coaxially provided with a transfer gear 391; the reciprocating frame 32 is provided with an arc-shaped reverse rack 323 and a forward rack 322 respectively located on both sides of the reverse rack 323; the forward rack 322 and the reverse rack 323 are used to drive the transfer gear 391 to rotate, and the transmission directions are opposite; the rotating shaft of the reciprocating frame 32 is parallel to the rotating shaft of the transfer frame 39 and does not overlap; the reciprocating frame 32 is coaxially provided with a reciprocating gear 321; the fixed plate 31 is longitudinally slidably connected with a reciprocating rack 33 meshing with the reciprocating gear 321; the reciprocating rack 33 is provided with a horizontal slide groove 331 parallel to the feed groove 232; the feed frame 21 is provided with a rack slide column 212 sliding in the horizontal slide groove 331.

[0046] The reverse rack 323 is coaxially distributed with the forward rack 322 , and the reverse rack 323 drives the transfer gear 391 to rotate 180°, and the forward rack 322 drives the transfer gear 391 to rotate 90°.

[0047] In the initial state, the transfer frame 39 is vertically upward, and the transfer gear 391 is meshed with an end of a forward rack 322 away from the reverse rack 323 .

[0048] The transfer rack 39 is provided with two symmetrically distributed sliding chambers 392; a sliding chamber 392 is sealed and slidably connected with a butt head 395; a sealing chamber 393 is provided on the transfer rack 39; the sealing chamber 393 is connected with each sliding chamber 392 through a connecting hole 394; a partition 36 capable of closing the connecting hole 394 is slidably connected in the sealing chamber 393; a piston body 34 for changing the air pressure in the sealing chamber 393 is sealed and slidably connected in the sealing chamber 393.

[0049] When the air pressure in the sliding chamber 392 changes, the abutting heads 395 slide. When the air pressure in the sliding chamber 392 increases, the two abutting heads 395 move toward each other to clamp the carbon brush holder assembly 9. When the air pressure in the sliding chamber 392 decreases, the two abutting heads 395 move away from each other to release the carbon brush holder assembly 9.

[0050] The transfer frame 39 is rotatably connected to a ratchet 37 that drives the piston body 34 to reciprocate; the transfer station 3 also includes a first ratchet plate 381 fixed to the cabinet 1 near the detection station 4 and a second ratchet plate 382 near the feed station 2; the first ratchet plate 381 is connected to the ratchet 37 by one-way transmission and drives the ratchet 37 to rotate 180°; the second ratchet plate 382 is connected to the ratchet 37 by one-way transmission and drives the ratchet 37 to rotate 180°.

[0051] The transfer station 3 also includes a rotating body 35 rotatably connected to the transfer frame 39 and coaxially arranged with the piston body 34; the inner periphery of the rotating body 35 is provided with a threaded groove 351 transmission-connected to the piston body 34; the rotating body 35 is provided with radial grooves 352 distributed along the radial direction; and an eccentric column 371 slidingly connected to the radial groove 352 is provided at an eccentric position on the ratchet 37.

[0052] When the ratchet wheel 37 rotates, the eccentric column 371 drives the rotating body 35 to swing back and forth through the radial sliding groove 352 , and then the rotating body 35 drives the piston body 34 to slide back and forth axially through the threaded groove 351 .

[0053] A return spring 361 is arranged between the partition 36 and the sealing cavity 392 to drive the partition 36 to close the connecting hole 394; a support frame 362 extending to the outside of the sealing cavity 392 is arranged on the partition 36; a first support plate 3811 capable of resisting the support frame 362 is arranged on the first ratchet plate 381; and a second support plate 3821 capable of resisting the support frame 362 is arranged on the second ratchet plate 382.

[0054] When the transfer frame 39 rotates toward the first pawl plate 381, after the ratchet 37 contacts the first pawl plate 381, the first pawl plate 381 drives the ratchet 37 to rotate. As the ratchet 37 rotates, the piston body 34 moves, changing the air pressure in the sealing chamber 393. When the rotating frame 39 rotates to face the brush holder assembly 9, the first abutment plate 3811 contacts the abutment 362 and drives the abutment 362 to move, the partition plate 36 is separated from the connecting hole 394, and then the sealing chamber 393 is connected with each sliding chamber 392, and the air pressure in the sliding chamber 392 changes. Similarly, when the transfer frame 39 moves toward the second pawl plate 381, the second pawl plate 381 drives the ratchet 37 to rotate, and the second abutment plate 3821 drives the abutment 362 to move.

[0055] The detection station 4 includes a capacitance detection unit 41, a spring detection unit 42, a plug detection unit 43, and a protector detection unit 44; a visual detector 46 is respectively provided on one side of the capacitance detection unit 41, the spring detection unit 42, the plug detection unit 43, and the protector detection unit 44; a fill light 45 is provided on one side of the protector detection unit 44.

[0056] A transfer station 3 is arranged between one side of the capacitance detection unit 41, the elastic detection unit 42, the plug detection unit 43, and the protector detection unit 44 and the feeding station 2; the transfer station 3 moves the carbon brush holder assembly 9 between the feeding station 2 and the capacitance detection unit 41, the elastic detection unit 42, the plug detection unit 43, and the protector detection unit 44.

[0057] The capacitor detection unit 41 is used to detect whether a capacitor is installed in the carbon brush holder assembly 9, whether the capacitor pins are skewed, and whether the capacitor pins are inserted into the slots.

[0058] The spring detection unit 42 is used to detect whether a spring is installed in the carbon brush holder assembly 9 and whether the spring is installed in place.

[0059] The plug detection unit 43 is used to detect whether the plug in the carbon brush holder assembly 9 is skewed.

[0060] The protector detection unit 44 is used to detect the relative position of the protector in the carbon brush holder assembly 9 and the color of the protector insulating paper. The fill light 45 can increase the brightness of the protector insulating paper to facilitate observation of its color.

[0061] The clamping station 5 includes a clamping cylinder 53 for clamping the carbon brush holder assembly 9 on the feed track 22, a longitudinal electric rail 52 for driving the clamping cylinder 53 to move longitudinally, and a moving electric rail 51 for driving the longitudinal electric rail 52 to move horizontally.

[0062] The waste station 6 includes a unloading conveyor belt 61 and a waste motor 62 for driving the unloading conveyor belt 61; the recycling station 7 includes a support frame 71, trays 72 evenly arranged longitudinally in the support frame 71, and a lifting cylinder 73 for pushing the trays 72 up and down; a unloading electric rail 8 is fixedly connected to the bottom of the support frame 71, and a movable frame 81 installed on the unloading electric rail 8 for driving the tray 72 to move.

[0063] The capacitance detection unit 41, the spring detection unit 42, the plug detection unit 43, and the protector detection unit 44 respectively have claws for clamping the carbon brush holder assembly 9; when the capacitance detection unit 41, the spring detection unit 42, the plug detection unit 43, and the protector detection unit 44 detect the carbon brush holder assembly 9, the transfer frame 39 is vertically upward, and the transfer frame 39 will not block the detection of the carbon brush holder assembly 9.

[0064] In the initial state, the transfer rack 39 is vertically upward, and the transfer gear 391 is meshed with one end of a forward rack 322 away from the reverse rack 323. At this time, the rotating gear 391 has a tendency to move toward the feeding station 2, and the two abutting heads 395 are away from each other. The sliding rod 213 is located in the feeding groove 232.

[0065] During work, the worker places the carbon brush holder assemblies 9 one by one at the end of the feed track 22. As the motor 25 drives the rotating frame 24 to move, the feed frame 21 circulates along the circular groove 230. During this process, the sliding rod 213 moves along the feed groove 232, and the feed push plate 211 pushes each carbon brush holder assembly 9 to move forward.

[0066] When the sliding rod 213 moves from the feed slot 232 through the connecting slot 233 to the reset slot 231, the feed frame 21 moves downward. At this time, the rack slide 212 drives the reciprocating rack 33 to move downward to the limit position, and each carbon brush holder assembly 9 does not move during this process.

[0067] As the reciprocating rack 33 moves downward, the reciprocating rack 33 drives the reciprocating gear 321 to rotate, and the reciprocating frame 32 rotates synchronously. Then, the forward rack 322 drives the transfer frame 39 to rotate 90° in the direction of the feed station 2 through the transfer gear 391, and the transfer frame 39 is directly opposite to a carbon brush holder assembly 9 on the feed track 22. During the process of the transfer frame 39 rotating 90°, the ratchet 37 contacts the second ratchet plate 382. The second ratchet plate 382 drives the ratchet 37 to rotate 180°, and the eccentric column 371 on the ratchet 37 drives the rotating body 35 to rotate, and then the threaded groove 351 on the rotating body 35 drives the piston body 34 to move into the sealing chamber 393, and the air pressure in the sealing chamber 393 increases.

[0068] When the transfer frame 39 rotates 90°, the second abutment plate 3821 abuts against the abutment frame 362 and forces the abutment frame 362 to move, so that the partition plate 36 no longer closes the connection hole. The sealing chamber 393 is connected to the sliding chamber 392, and the air pressure in the sliding chamber 392 increases, forcing the two abutment heads 395 to approach each other, and then the two abutment heads 395 clamp a carbon brush holder assembly 9.

[0069] Then the reciprocating frame 32 continues to rotate, the reverse rack 323 meshes with the transfer gear 391, and the transfer frame 39 rotates 180° toward the detection station 4, and the transfer frame 39 clamps a carbon brush holder assembly 9 into the detection station 4. Finally, the transfer frame 39 moves into the detection station 4. In this process, the ratchet 37 is first separated from the second ratchet plate 382, ​​at which time the second ratchet plate 382 does not drive the ratchet 37 to rotate, the support frame 362 is separated from the second support plate 3821, and the partition plate 36 closes the connecting hole 394. After that, the ratchet 37 contacts the first ratchet plate 381, and the first ratchet plate 3811 drives the ratchet 37 to rotate 180°. The ratchet 37 drives the rotating body 35 to rotate, and the rotating body 35 drives the piston body 34 to move away from the sealing chamber 393, and the air pressure in the sealing chamber 393 decreases.

[0070] After that, the support frame 362 contacts the first support plate 3811, and the first support plate 3811 drives the support frame 362 to move, and the partition plate 36 is separated from the connecting hole 394. The sealing chamber 393 is connected with the sliding chamber 392, and the air pressure in the sliding chamber 392 is reduced, and the two abutting heads 395 move away from each other, and then the abutting heads 395 no longer clamp the carbon brush holder assembly 9, so that the carbon brush holder assembly 9 is placed on the detection station 4.

[0071] Then the reciprocating frame 32 continues to rotate, the other positive rack 322 meshes with the transfer gear 391, and the transfer frame 39 rotates 90° in the direction away from the detection station 4. The transfer frame 39 moves vertically upward. During this process, the first pawl plate 381 does not drive the ratchet wheel 37 to rotate, and the partition plate 36 closes the connecting hole 394 again. The detection station 4 detects the carbon brush holder assembly 9. At this point, the sliding rod 213 moves into the reset groove 231 through the connecting groove 233.

[0072] The rotating frame 24 continues to move, the feed frame 21 moves backward along the reset groove 231, and the feed push plate 211 moves backward synchronously under each carbon brush holder assembly 9. Then the sliding rod 213 moves from the reset groove 231 through the connecting groove 233 to the feed groove 232. During this process, the feed frame 21 moves upward, and the feed push plate 211 is inserted between each carbon brush holder assembly 9. At the same time, the rack slide column 212 on the feed frame 21 drives the reciprocating rack 33 to move upward to the limit position.

[0073] As the reciprocating rack 33 moves upward, the reciprocating rack 33 drives the reciprocating frame 32 to rotate. The forward rack 322 on the reciprocating frame 32 drives the transfer frame 39 to rotate 90° in the direction of the detection station 4. During this process, the ratchet 37 contacts the first pawl plate 381, and the first pawl plate 381 drives the ratchet 37 to rotate 180°, and the piston body 34 moves toward the inside of the sealing chamber 393, and the air pressure in the sealing chamber 393 increases. Finally, the first abutment plate 3811 drives the partition plate 36 to move, and the sealing chamber 393 is connected to the sliding chamber 392. The air pressure in the sliding chamber 392 increases, and the two abutment heads 395 clamp the carbon brush holder assembly 9 on the detection station 4.

[0074] Then the reciprocating frame 32 continues to rotate, and the reverse rack 323 drives the transfer frame 39 to rotate 180°. The transfer frame 39 will drive the carbon brush holder assembly 9 on the detection station 4 to move to the feeding station 2, and then put the carbon brush holder assembly 9 back to the feeding station 2. In this process, the ratchet 37 contacts the second pawl plate 382, ​​the ratchet 37 rotates 180°, the piston body 34 moves away from the sealing chamber 393, and the air pressure in the sealing chamber 393 decreases. Finally, the second abutment plate 3821 drives the partition plate 36 to move, the sealing chamber 393 is connected to the sliding chamber 392, the air pressure in the sliding chamber 392 decreases, and the two abutments 395 loosen the carbon brush holder assembly 9, and then the carbon brush holder assembly 9 is placed back on the feeding station 2.

[0075] Then the reciprocating frame 32 continues to rotate, and the forward gear 322 drives the transfer frame 39 to rotate 90°, and the transfer station 3 returns to the initial state. At the same time, the sliding rod 213 moves into the feed groove 232, and the feed station 2 returns to the initial state. At this time, the motor 25 drives the rotating frame 24 to rotate 360°, completing a cycle.

[0076] Then the cycle is repeated, the feeding station 2 gradually drives each carbon brush holder assembly 9 to move forward, and at the same time the transfer station 3 transfers the carbon brush holder assembly 9 from the feeding station 2 to the inspection station 4. After the inspection station 4 completes the inspection of the carbon brush holder assembly 9, the transfer station 3 again places the carbon brush holder assembly 9 from the inspection station 4 to the feeding station 2.

[0077] By performing the above steps, each transfer station 3 places the carbon brush holder assembly 9 on the capacitor detection unit 41, the spring detection unit 42, the plug detection unit 43, and the insulating paper detection unit 44, and the visual sensor 46 performs corresponding detection on the carbon brush holder assembly 9 in turn to determine whether the carbon brush holder assembly 9 is a qualified product or a failed product.

[0078] The unloading electric rail 8 drives the moving frame 81 to move below the support frame 71. The lifting cylinder 73 drives each tray 72 to descend, and the lowermost tray 72 is placed on the upper end of the moving frame 81. Then the unloading electric rail 8 drives the moving frame 81 to move, and the moving frame 81 will drive the lowermost tray 72 to leave the support frame 71 together. The remaining trays 72 in the support frame 71 fall onto the lifting cylinder 73. Then the lifting cylinder 73 pushes the remaining trays 72 to move upward for the next use.

[0079] As the feeding station 2 continues to work, each carbon brush holder assembly 9 moves toward the clamping station 5. The clamping station 5 works, and the clamping cylinder 53 clamps a carbon brush holder assembly 9 on the feeding track 22. The longitudinal electric rail 52 drives the clamping cylinder 53 and the carbon brush holder assembly 9 to move upward together. The moving electric rail 51 drives the carbon brush holder assembly 9 to move horizontally. If the carbon brush holder assembly 9 is a qualified product, the carbon brush holder assembly 9 will be placed on the tray 72. If the carbon brush holder assembly 9 is a defective product, the carbon brush holder assembly 9 will be placed on the unloading conveyor belt 61.

[0080] When the carbon brush holder assembly 9 on the tray 72 is fully laid, the worker takes away the tray 72. The moving frame 81 takes a tray 72 in a supporting frame 71 again.
