DETAILED DESCRIPTION

[0034] Specific embodiment 1: Please refer to Figure 1-Figure 12 The carbon brush holder assembly conveying device comprises a cabinet 11 and a feed guide rail 12, a detection unit 13, a pick-and-place unit 2, and a finished product unit 4 arranged on the cabinet 11; the finished product unit 4 has two and is symmetrically distributed; a plurality of tray assemblies 5 are arranged longitudinally on each of the finished product units 4; an electric slide rail 6 for conveying the tray assembly 5 is arranged between two finished product units 4 on the cabinet 11; the tray assembly 5 comprises a base 52 and a tray 51 movably mounted on the base 52; the finished product unit 4 comprises a finished product rack 41; each base 52 slides longitudinally in the finished product rack 41; lifting mechanisms for driving the base 52 to move are respectively arranged on both sides of the finished product rack 41; the lifting mechanism comprises two lifting plates 42 arranged longitudinally and rotatably connected to the finished product rack 41; the two lifting plates 42 rotate synchronously; a support column 42 is arranged at an eccentric position on the lifting plate 42; lifting bosses 521 capable of contacting the support column 421 are respectively arranged on both sides of the base 52; the rotating shaft of the lifting plate 42 and one end of the lifting boss 521 are located in the same vertical plane.

[0035] The two lifting mechanisms are connected to each other through a synchronous shaft 43 , and the synchronous shaft 43 is connected to a lifting plate 42 in the lifting mechanism through a transmission belt 431 .

[0036] The two lifting plates 42 are connected by a synchronous belt 422. When the support column 421 is located directly above the rotating shaft of the lifting plate 42, the support column 421 abuts against the lower end of the lifting boss 521. At this time, if the lifting plate 42 rotates forward, the horizontal height of the support column 421 decreases, and the support column 421 moves to the bottom of the lifting boss 521, and then the base 52 moves downward synchronously with the descent of the support column 421. When the support column 421 moves to the bottom of the rotating shaft of the lifting plate 42, the base 52 also moves to the lower limit position, and then the lifting plate 42 continues to rotate, the support column 421 separates from the lifting boss 521, and the support column 421 no longer drives the base 52 to move. When the support column 421 moves forward and moves again to the top of the rotating shaft of the lifting plate 42, the support column 421 abuts against the upper lifting boss 521, thereby achieving the descent of each base 52 by a certain distance.

[0037] At this time, if the lifting plate 42 rotates in the opposite direction, the level of the support column 421 decreases, and the support column 421 moves to the outside of the lifting boss 521 and no longer contacts the lifting boss 521. Thereafter, the lifting plate 42 continues to rotate, and when the lifting plate 42 rotates until the support column 421 is directly below the rotating shaft of the lifting plate 42, the support column 421 contacts the lower end of the lifting boss 521 on the base 52 below the lifting plate 42. Then, the lifting plate 42 continues to rotate in the opposite direction, and the level of the support column 421 increases, and then the support column 421 drives the base 52 to move upward, thereby completing the lifting process of each base 52.

[0038] The outer periphery of the base 52 is evenly provided with positioning columns 522 extending upward; the base 52 is provided with a plurality of clamping mechanisms; the clamping mechanism includes a deflection plate 56 rotatably connected to the base 52 and capable of abutting against the tray 51, and a pressing portion 53 longitudinally slidably connected to the base 52 and driving the deflection plate 56 to rotate; for two adjacent bases 52, the upper end of a pressing portion 53 abuts against the lower end of the pressing portion 53 above; the finished product rack 41 is provided with a longitudinally arranged guide plate 411; the upper part of the guide plate 411 is provided with a top plate 412 which can abut against the pressing portion 53 and thereby drive the deflection plate 56 to separate from the tray 51.

[0039] The upper end of the positioning column 522 on one base 52 abuts against the lower end of the positioning column 522 on the upper base 52 , so that the bases 52 are arranged in sequence longitudinally, and a space for placing the tray 51 is formed between two adjacent bases 52 .

[0040] As the number of bases 52 in the finished product rack 41 increases, the top base 52 gradually moves upward. When the pressing portion 53 in the top base 52 abuts against the top plate 412, the top plate 412 will drive the pressing portion 53 to move downward relative to the base 52, and at the same time, the pressing portion 53 drives each pressing portion 53 below to move synchronously, so that all the deflection plates 56 are separated from the tray 51. At this time, the worker can remove the tray 51 from the base 52 or place a new tray 51 on the base 52.

[0041] The deflection plate 56 is coaxially provided with a deflection gear 561; the clamping mechanism also includes a rack 55 slidably connected to the lower end of the base 52 and meshing with the deflection gear 561; the side wall of the rack 55 is provided with an inclined groove 551; the side wall of the pressing portion 53 is provided with a sliding rod 531 slidably connected to the inclined groove 551; a pressing spring 54 is provided between the pressing portion 53 and the base 52 to drive the pressing portion 53 to return to its original position.

[0042] When the pressing portion 53 moves downward, the pressing spring 54 contracts, and the slide bar 531 drives the rack 55 to slide through the inclined groove 551 , and then the rack 55 drives the deflection plate 56 to rotate, and the deflection plate 56 is separated from the tray 51 .

[0043] Deflection plates 56 are provided on both sides of the tray 51 on the base 52. Through the rotation of each deflection plate 56, the tray 51 is clamped in the middle of the base 52 by each deflection plate 56 to prevent the tray 51 from shaking.

[0044] The finished product unit 4 also includes a driving gear 46 that is transmission-connected to a lifting plate 42, an outer ring 45 that is coaxially arranged with the driving gear 46, and a clockwork spring 462 installed between the driving gear 46 and the outer ring 45; a receiving plate 61 for receiving the tray assembly 5 is provided on the electric slide rail 6; driving components 60 are respectively provided on both sides of the upper end of the receiving plate 61; a driving component 60 is transmission-connected to a finished product unit 4; the driving component 60 includes a feed ratchet bar 63 that is unidirectionally transmission-connected to the outer ring 45.

[0045] When the electric slide rail 6 works, the electric slide rail 6 drives the receiving plate 61 to move between the two finished product racks 41 .

[0046] The finished product rack 41 is slidably connected with a release rack 48 for limiting the rotation of the driving gear 46; one end of the driving gear 46 is provided with a radially distributed limit protrusion 461; the release rack 48 is provided with an upper stop plate 482 and a lower stop plate 483 that can abut against the limit protrusion 461; at the same time, the limit protrusion 461 only abuts against one of the upper stop plate 482 and the lower stop plate 483; the finished product rack 41 is rotatably connected with a release ratchet 49 that drives the release rack 48 to reciprocate; the driving component 60 also includes a release pawl bar 64 that is unidirectionally connected to the release ratchet 49; when the receiving plate 61 moves, the feed pawl bar 63 first drives the outer ring 45 to rotate, and then the release pawl bar 64 drives the release ratchet 49 to rotate.

[0047] The release frame 48 is provided with a horizontally arranged slide groove 481; the release ratchet 49 is provided with an eccentric column 491 slidably connected to the slide groove 481 at an eccentric position; when the release ratchet 49 rotates, the eccentric column 491 drives the release frame 48 to slide longitudinally. The upper stop plate 482 is located above the lower stop plate 483.

[0048] When the release frame 48 is at the lower limit position, the upper stop plate 482 abuts against the limit protrusion 461, and the driving gear 46 cannot rotate; at this time, the release ratchet 49 rotates 180°, the eccentric column 491 drives the release frame 48 to move upward, the upper stop plate 482 gradually moves upward and then separates from the limit protrusion 461, and the lower stop plate 483 moves upward synchronously. After the upper stop plate 482 separates from the limit protrusion 461, the driving gear 46 will rotate 180°, and the limit protrusion 461 will abut against the lower stop plate 483, so that the driving gear 46 will no longer move.

[0049] After the release ratchet 49 rotates 180°, the mainspring 462 will drive the stop gear 46 to quickly rotate 180°.

[0050] A feed ratchet ring 451 coaxially arranged on the outer ring 45 and cooperating with the feed ratchet bar 63 ; a non-return ratchet ring 452 coaxially arranged on the outer ring 45 ; and a non-return ratchet ring 47 cooperating with the non-return ratchet ring 452 is fixedly connected to the finished product rack 41 .

[0051] After the feed pawl bar 63 contacts the feed ratchet ring 451, the feed pawl bar 63 drives the outer ring 45 to rotate, and the spring 462 accumulates force. When the feed pawl bar 63 is no longer in contact with the feed ratchet ring 451, the non-return ratchet ring 452 cooperates with the non-return pawl ring 47 to prevent the outer ring 45 from rotating in the opposite direction, thereby preventing the spring 462 from releasing torque through the outer ring 45.

[0052] The finished product rack 41 is rotatably connected to a reversing rack 44; the reversing rack 44 is rotatably connected to two mutually meshing forward gears 444 and a reverse gear 443 at an eccentric position; the reverse gear 443 and a forward gear 444 close to the driving gear 46 can mesh with the driving gear 46; a lifting gear 423 is coaxially arranged on one of the lifting plates 42 and can mesh with the reverse gear 443 or a forward gear 444 away from the driving gear 46.

[0053] When the reversing frame 44 rotates until the forward gear 444 is respectively meshed with the driving gear 46 and the lifting gear 423 , the driving gear 46 rotates to drive the lifting gear 423 to rotate forward, thereby rotating the lifting plate 42 forward.

[0054] When the reversing frame 44 rotates until the reverse gear 443 is respectively meshed with the driving gear 46 and the lifting gear 423 , the driving gear 46 drives the lifting plate 42 to rotate in the reverse direction.

[0055] The side wall of the reversing frame 44 is provided with a reverse abutment surface 441 and a positive abutment surface 442 which are non-parallel to each other; the driving component 60 also includes a reversing portion 65 driven by the gravity of the tray assembly 5 which slides longitudinally on the receiving plate 61; a reversing groove 66 is provided on one side of the reversing portion 65; two parallel and horizontally arranged reverse pressure surfaces 661 and positive pressure surfaces 662 are provided in the reversing groove 66; a reversing spring is provided between the reversing portion 65 and the receiving plate 61 to drive the reversing portion 65 to return to its original position upward.

[0056] When the upper end of the receiving plate 61 has the tray assembly 5, the tray assembly 5 presses down the reversing portion 65, so that the reversing portion 65 is located at the lower limit position, and the reverse pressure surface 661 is directly opposite to the reverse abutment surface 441. At this time, the receiving plate 61 moves downward to the finished product rack 41, and the reverse pressure surface 661 will contact the reverse abutment surface 441 and force the reverse abutment surface 441 to move to the horizontal, so that the reversing rack 44 rotates, and the reverse gear 443 is respectively engaged with the driving gear 46 and the lifting gear 423.

[0057] When there is no tray assembly 5 on the upper end of the receiving plate 61, the reversing portion 65 is located at the upper limit position, and the positive pressure surface 662 is directly opposite to the positive abutment surface 442. At this time, the receiving plate 61 moves downward to the finished product rack 41, and the positive pressure surface 662 drives the positive abutment surface 442 to rotate to the horizontal, and then the reversing rack 44 rotates, and the positive gear 444 is respectively engaged with the driving gear 46 and the lifting gear 423.

[0058] The upper end of the receiving plate 61 is provided with a guide column 62 extending upward; the base 52 is provided with a guide opening 523 slidably connected to the guide column 62; through the cooperation between the guide column 62 and the guide opening 523, the base 52 can only slide longitudinally relative to the receiving plate 61.

[0059] The pick-and-place unit 2 includes a mobile clamp 23 for clamping the carbon brush holder assembly, a longitudinal electric rail 22 for driving the mobile clamp 23 to move longitudinally, and a transverse electric rail 21 for driving the longitudinal electric rail 22 to move horizontally; a defective product conveyor belt 3 is provided on one side of the finished product unit 4; and a visual inspection unit 18 for observing the current position of the carbon brush holder assembly is provided on one side of the mobile clamp 23.

[0060] The detection unit 13 includes a capacitance detection unit 14, a spring detection unit 15, a plug detection unit 16, and a protector detection unit 17; a visual detection unit 18 is respectively provided on one side of the capacitance detection unit 14, the spring detection unit 15, the plug detection unit 16, and the protector detection unit 17.

[0061] The capacitor detection unit 14 is used to detect whether a capacitor is installed in the carbon brush holder assembly, whether the capacitor pins are skewed, and whether the pins inside the capacitor are inserted into the slots.

[0062] The spring detection unit 15 is used to detect whether a spring is installed in the carbon brush holder assembly and whether the spring is installed in place.

[0063] The plug detection unit 16 is used to detect whether the plug in the carbon brush holder assembly is skewed.

[0064] The protector detection unit 17 is used to detect the relative position of the protector in the carbon brush holder assembly and the color of the protector insulating paper.

[0065] In the initial state, one finished product rack 41 does not contain a tray assembly 5, and another finished product rack 41 contains multiple tray assemblies 5, the pressing portion 53 in the uppermost tray assembly 5 abuts against the top plate 412, and each deflection plate 56 is separated from the tray 51, and each tray 51 does not contain a carbon brush holder assembly. There is no tray assembly 5 on the receiving plate 61, and the reversing portion 65 is located at the upper limit position.

[0066] Before the equipment is put into operation, a tray assembly 5 is placed on the receiving plate 61. The specific operation is as follows.

[0067] The electric slide rail 6 drives the receiving plate 61 to move below the finished product rack 41 with the tray assembly 5 until the receiving plate 61 moves to the right below the tray assembly 5. In this process, the positive pressure surface 662 contacts the positive abutment surface 442 and drives the reversing rack 44 to rotate, and the positive gear 444 is respectively engaged with the driving gear 46 and the lifting gear 423. At the same time, the feed pawl bar 63 cooperates with the feed ratchet ring 451, so that the outer ring 45 rotates and the spring accumulates power.

[0068] After the feed pawl bar 63 separates from the feed ratchet ring 451, the release pawl bar 64 contacts the release ratchet 49, and the release ratchet 49 rotates 180°. At this time, the receiving plate 61 moves to the bottom of the tray assembly 5, and the reversing groove 66 separates from the reversing frame 44, and the reversing frame 44 remains in the current state. At the same time, the release frame 48 cooperates with the limiting protrusion 461, and the driving gear 46 rotates 180° under the action of the spring 462. Through the transmission of the forward gear 444, the lifting plate 42 rotates 360° in the forward direction.

[0069] As each lifting plate 42 rotates 360° in the forward direction, the supporting column 421 rotates downward and drives each tray assembly 5 to move downward, and the tray assembly 5 at the bottom will be placed on the receiving plate 61, and the guide opening 523 on the base 52 of the bottom tray assembly 5 will slide and plug with the guide column 62. Then, after the supporting column 421 passes under the rotating shaft of the lifting plate 42, the supporting column 421 no longer contacts the limiting protrusion 461, and the supporting column 421 moves upward. Finally, the supporting column 421 abuts against the two tray assemblies 5 that are not at the bottom.

[0070] Then the electric slide rail 6 drives the receiving plate 61 to move between the two finished product racks 41 , and the receiving plate 61 drives a tray assembly 5 to leave the finished product rack 41 .

[0071] When the carbon brush holder assembly is inspected, the feed guide rail 12 drives the carbon brush holder assembly to move to the inspection unit 13. The inspection unit 13 inspects the carbon brush holder assembly and determines whether the carbon brush holder assembly is a qualified product or a defective product.

[0072] The pick-and-place unit 2 places the defective carbon brush holder assemblies on the defective conveyor belt 3 , and places the qualified carbon brush holder assemblies in the tray 51 on the receiving plate 61 in sequence.

[0073] When the tray 51 is filled with carbon brush holder assemblies, the tray assembly 5 filled with carbon brush holder assemblies is placed on another finished product rack 41. The specific process is as follows.

[0074] At this time, the receiving plate 61 has a tray assembly 5, and then the reversing part 65 moves to the lower limit position under the gravity of the tray assembly 5, and the reverse pressure surface 661 faces the reverse abutment surface 441. The electric slide rail 6 drives the receiving plate 61 to move in the direction of another finished product rack 41 until the receiving plate 61 moves to the bottom of the finished product rack 41. During this process, the reverse pressure surface 661 drives the reverse abutment surface 441 to move to the horizontal, and then the reversing rack 44 rotates, and the reverse gear 443 engages with the driving gear 46 and the lifting gear 423 respectively. At the same time, the feed ratchet bar 63 drives the feed ratchet ring 451 to rotate, and the spring accumulates power.

[0075] Then the release pawl bar 64 cooperates with the release ratchet 49 to drive the release ratchet 49 to rotate 180°. At this time, the receiving plate 61 is located directly below the finished product rack 41, and the reversing groove 66 is separated from the reversing rack 44, and the reversing rack 44 remains in the current state. Thereafter, as the release ratchet 49 rotates 180°, the release rack 48 moves, the limiting protrusion 461 is no longer restricted, and the driving gear 46 will rotate 180° under the action of the spring 462. And through the transmission of the reverse gear 443, the lifting plate 42 rotates 360° in the opposite direction.

[0076] As the lifting plate 42 rotates 360° in the opposite direction, the lifting plate 42 drives the tray assembly 5 on the receiving plate 61 to move upward into the finished product rack 41 , thereby completing the recovery of the tray assembly 5 .

[0077] Repeat the above process, the receiving plate 61 takes the tray assembly 5 without carbon brush holder assembly from one finished product rack 41, and after the operation of the pick-and-place unit 2, the tray assembly 5 is filled with carbon brush holder assembly. The tray assembly 5 filled with carbon brush holder assembly is placed on another finished product rack 41.

[0078] Finally, all the tray assemblies 5 on one finished product rack 41 are removed, and the other finished product rack 41 is filled with tray assemblies 5, and the tray 51 therein is filled with carbon brush holder assemblies. Since the other finished product rack 41 is filled with tray assemblies 5 at this time, the pressing part 65 in the uppermost tray assembly 5 abuts against the top plate 412, and the top plate 412 drives each pressing part 65 to move downward relative to the base 52, and each deflection plate 56 no longer abuts against the tray 51. At this time, the worker removes each tray 51 filled with carbon brush holder assemblies from the base 52, and puts an empty tray 51 on the base 52. At this point, the two finished product units 4 are restored to their initial state.
