Description

Technical Field

[0001] This invention belongs to the field of conveying, and more specifically, relates to a carbon brush holder assembly conveying device. Background Technology

[0002] The carbon brush holder assembly is one of the motor accessories. Internally, it contains components such as capacitors, springs, connectors, and protectors. To ensure proper motor operation, all components within the carbon brush holder assembly must be properly installed, necessitating internal testing to ensure the assembly meets quality standards.

[0003] Currently, during the process of collecting carbon brush holder assemblies, workers need to remove each tray promptly once it is full; otherwise, normal operation cannot continue. This increases labor costs. Summary of the Invention

[0008] As a further improvement of the present invention, the finished product unit further includes a drive gear that is drivenly connected to a lifting plate, an outer ring that is coaxially arranged with the drive gear, and a spring installed between the drive gear and the outer ring; the electric slide rail is provided with a receiving plate for receiving the pallet assembly; driving components are respectively provided on both sides of the upper end of the receiving plate; a driving component is drivenly connected to a finished product unit; the driving component includes a feed pawl that is driven unidirectionally connected to the outer ring.

[0009] As a further improvement of the present invention, a release frame for limiting the rotation of the drive gear is slidably connected to the finished product frame; a limiting protrusion distributed radially is provided at one end of the drive gear; an upper stop plate and a lower stop plate are provided on the release frame that can abut against the limiting protrusion; at the same time, the limiting protrusion abuts against only one of the upper stop plate and the lower stop plate; a release ratchet that drives the release frame to reciprocate is rotatably connected to the finished product frame; the driving component also includes a release pawl bar that is unidirectionally connected to the release ratchet bar; when the receiving plate moves, the feed pawl bar first drives the outer ring to rotate, and then the release pawl bar drives the release ratchet bar to rotate.

[0010] As a further improvement of the present invention, a feed ratchet ring coaxially provided on the outer ring to cooperate with the feed pawl bar; a check ratchet ring coaxially provided on the outer ring; and a check pawl ring cooperating with the check ratchet ring fixedly connected to the finished product frame.

[0011] As a further improvement of the present invention, a reversing frame is rotatably connected to the finished product frame; the reversing frame is rotatably connected to two meshing forward gears and one reverse gear at an eccentric position; the reverse gear and a forward gear close to the driving gear can mesh with the driving gear; a lifting gear is coaxially arranged on the lifting plate, which can mesh with the reverse gear or a forward gear far away from the driving gear.

[0012] As a further improvement of the present invention, the side wall of the reversing frame is provided with non-parallel opposing and forward opposing surfaces; the driving component also includes a reversing part that slides longitudinally on the receiving plate and is driven by the gravity of the pallet assembly; a reversing groove is provided on one side of the reversing part; two parallel and horizontally arranged opposing and forward opposing pressing surfaces are provided in the reversing groove; a reversing spring is provided between the reversing part and the receiving plate to drive the reversing part to return to its upward position.

[0013] As a further improvement of the present invention, the pick-and-place unit includes a movable gripper for holding the carbon brush holder assembly, a longitudinal electric rail for driving the movable gripper to move longitudinally, and a transverse electric rail for driving the longitudinal electric rail to move horizontally; a defective product conveyor belt is provided on one side of the finished product unit; a visual inspection unit for observing the current position of the carbon brush holder assembly is provided on one side of the movable gripper.

[0014] As a further improvement of the present invention, the detection unit includes a capacitance detection unit, a spring detection unit, a plug detection unit, and a protector detection unit; a visual detection unit is respectively provided on one side of the capacitance detection unit, the spring detection unit, the plug detection unit, and the protector detection unit.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the present solution uses the forward or reverse rotation of the lifting plate to make the pallet assembly move downward or upward, so as to complete the process of placing the pallet assembly on the receiving plate or placing the pallet assembly on the receiving plate on the finished product rack. When all the pallets are full of carbon brush rack assemblies, the workers collect the pallets in a centralized manner, reducing the frequency of worker operations and reducing labor costs.

[0016] This solution uses two finished product units, with a receiving plate moving between them. When there are no pallet assemblies on the receiving plate, after the receiving plate moves under the finished product rack, the pallet assemblies from the finished product rack will be placed on the receiving plate. When there are pallet assemblies on the receiving plate, after the receiving plate moves under the finished product rack, the pallet assemblies will be lifted into the finished product rack for storage.

[0017] This solution incorporates a reversing section that utilizes the gravity of the pallet assembly to drive the reversing frame to rotate. This rotation of the drive gear can either drive the lifting plate to rotate in the forward direction via the forward gear, causing each pallet assembly to move downwards and be placed on the receiving plate, or drive the lifting plate to rotate in the reverse direction via the reverse gear, causing each pallet assembly to move upwards and be placed into the finished product rack for storage.

[0018] This solution utilizes the horizontal movement of the receiving plate to drive the pallet assembly, facilitating the placement of the carbon brush holder assembly onto the pallet by the pick-and-place unit. Simultaneously, the feed pawl on the receiving plate drives the outer ring to rotate unidirectionally, forcing the spring to store power for the rotating seat of the drive gear. Furthermore, the release pawl on the receiving plate engages with the release ratchet to drive the release frame, thereby moving the receiving plate below the finished product rack. The drive gear then engages with the release frame, causing the lifting plate to rotate 360°.

[0019] This solution uses only one power element—the electric slide rail—to store and place pallet components at night, reducing the need for additional power elements and saving costs. Attached Figure Description

[0034] Specific Implementation Example 1: Please refer to... Figures 1-12 The carbon brush holder assembly conveying equipment includes a cabinet 11 and a feeding guide rail 12, a detection unit 13, a pick-and-place unit 2, and a finished product unit 4 disposed on the cabinet 11. There are two finished product units 4, symmetrically distributed. Multiple tray assemblies 5 are arranged longitudinally on each finished product unit 4. An electric slide rail 6 for transporting the tray assemblies 5 is disposed on the cabinet 11 between the two finished product units 4. Each tray assembly 5 includes a base 52 and a tray 51 movably mounted on the base 52. Each finished product unit 4 includes a finished product rack 41. Each base 52 slides longitudinally within the finished product rack 41. Lifting mechanisms for driving the base 52 are respectively disposed on both sides of the finished product rack 41. Each lifting mechanism includes two longitudinally arranged lifting plates 42 rotatably connected to the finished product rack 41. The two lifting plates 42 rotate synchronously. An abutment 421 is disposed eccentrically on each lifting plate 42. Lifting bosses 521 capable of contacting the abutment 421 are respectively disposed on both sides of the base 52. The rotation axis 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 by a synchronous shaft 43, and the synchronous shaft 43 is connected to a lifting plate 42 in the lifting mechanism by a transmission belt 431.

[0036] The two lifting plates 42 are connected by a synchronous belt 422. When the abutment 421 is directly above the pivot of the lifting plate 42, it abuts against the lower end of the lifting boss 521. If the lifting plate 42 rotates forward at this time, the horizontal height of the abutment 421 decreases, and the abutment 421 moves below the lifting boss 521, causing the base 52 to move downward synchronously with the descent of the abutment 421. When the abutment 421 moves directly below the pivot of the lifting plate 42, the base 52 also moves to its lower limit position. Afterward, the lifting plate 42 continues to rotate, the abutment 421 separates from the lifting boss 521, and the abutment 421 no longer drives the base 52 to move. When the abutment 421 moves forward and moves again directly above the pivot of the lifting plate 42, the abutment 421 abuts against the upper lifting boss 521, thereby causing each base 52 to descend a certain distance.

[0037] If the lifting plate 42 rotates in the opposite direction at this time, the horizontal height of the abutment column 421 decreases, and the abutment column 421 moves to the outside of the lifting boss 521, no longer contacting the lifting boss 521. Then, the lifting plate 42 continues to rotate. When the lifting plate 42 rotates to the point where the abutment column 421 is directly below the axis of rotation of the lifting plate 42, the abutment column 421 abuts against 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 horizontal height of the abutment column 421 increases, thereby driving the base 52 to move upward. This completes the rising process of each base 52.

[0038] The base 52 is uniformly provided with upwardly extending positioning posts 522 on its outer periphery; the base 52 is provided with multiple 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 part 53 slidably connected to the base 52 to drive the deflection plate 56 to rotate; for two adjacent bases 52, the upper end of one pressing part 53 abuts against the lower end of the pressing part 53 above it; 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 capable of abutting against the pressing part 53 and thus driving the deflection plate 56 to separate from the tray 51.

[0039] The upper end of the positioning post 522 on one base 52 abuts against the lower end of the positioning post 522 on the upper base 52, and the bases 52 are arranged longitudinally in sequence, 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 uppermost base 52 gradually moves upward. When the pressing part 53 in the uppermost base 52 abuts against the top plate 412, the top plate 412 will drive the pressing part 53 to move downward relative to the base 52. At the same time, the pressing part 53 will synchronously drive all the pressing parts 53 below to move synchronously, thereby separating all the deflection plates 56 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 that is slidably connected to the lower end of the base 52 and meshes with the deflection gear 561; the rack 55 has inclined grooves 551 distributed on its side wall; the pressing part 53 has a slide rod 531 that is slidably connected to the inclined grooves 551 on its side wall; and a pressing spring 54 that drives the pressing part 53 to reset is provided between the pressing part 53 and the base 52.

[0042] When the pressing part 53 moves downward, the pressing spring 54 contracts, and the slide rod 531 drives the rack 55 to slide through the inclined groove 551. In turn, the rack 55 drives the deflection plate 56 to rotate, and the deflection plate 56 separates from the tray 51.

[0043] A deflection plate 56 is provided on both sides of the tray 51 on the base 52. By rotating each deflection plate 56, the tray 51 is clamped in the middle of the base 52 by each deflection plate 56, so as to prevent the tray 51 from shaking.

[0044] The finished product unit 4 also includes a drive gear 46 that is drivenly connected to a lifting plate 42, an outer ring 45 that is coaxially arranged with the drive gear 46, and a spring 462 installed between the drive gear 46 and the outer ring 45; the electric slide rail 6 is provided with a receiving plate 61 for receiving the pallet assembly 5; the upper ends of the receiving plate 61 are respectively provided with driving components 60; one driving component 60 is drivenly connected to one finished product unit 4; the driving component 60 includes a feed pawl 63 that is unidirectionally driven connected to the outer ring 45.

[0045] When the electric slide rail 6 is in operation, it will drive the receiving plate 61 to move between the two finished product frames 41.

[0046] The finished product frame 41 is slidably connected to a release frame 48 for limiting the rotation of the drive gear 46; one end of the drive gear 46 is provided with a radially distributed limiting protrusion 461; the release frame 48 is provided with an upper stop plate 482 and a lower stop plate 483 that can abut against the limiting protrusion 461; at the same time, the limiting protrusion 461 abuts against only one of the upper stop plate 482 and the lower stop plate 483; the finished product frame 41 is rotatably connected to a release ratchet 49 that drives the release frame 48 to reciprocate; the drive component 60 also includes a release pawl 64 that is unidirectionally connected to the release ratchet 49; when the receiving plate 61 moves, the feed pawl 63 first drives the outer ring 45 to rotate, and then the release pawl 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 mechanism 48 is at its lower limit position, the upper stop plate 482 abuts against the limiting protrusion 461, preventing the drive gear 46 from rotating. At this time, the release ratchet 49 rotates 180°, and the eccentric column 491 drives the release mechanism 48 to move upward. The upper stop plate 482 gradually moves upward and separates from the limiting protrusion 461, while the lower stop plate 483 moves upward simultaneously. After the upper stop plate 482 separates from the limiting protrusion 461, the drive gear 46 will rotate 180°, and the limiting protrusion 461 will abut against the lower stop plate 483, causing the drive gear 46 to stop moving.

[0049] After the ratchet 49 is released and rotated 180°, the spring 462 will drive the stop gear 46 to rotate 180° quickly.

[0050] The outer ring 45 is coaxially provided with a feed ratchet ring 451 that cooperates with the feed pawl bar 63; the outer ring 45 is coaxially provided with a check ratchet ring 452; and the finished product frame 41 is fixedly connected with a check ratchet ring 47 that cooperates with the check ratchet ring 452.

[0051] After the feed pawl 63 abuts against the feed ratchet ring 451, the feed pawl 63 drives the outer ring 45 to rotate, and the mainspring 462 stores power. When the feed pawl 63 is no longer in contact with the feed ratchet ring 451, the check ratchet ring 452 and the check pawl ring 47 cooperate to prevent the outer ring 45 from rotating in the opposite direction, thus preventing the mainspring 462 from releasing torque through the outer ring 45.

[0052] A reversing frame 44 is rotatably connected to the finished product frame 41; the reversing frame 44 is rotatably connected to two meshing forward gears 444 and one reverse gear 443 at an eccentric position; the reverse gear 443 and a forward gear 444 near the driving gear 46 can mesh with the driving gear 46; a lifting gear 423 is coaxially arranged on a lifting plate 42, which 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 to the point where the forward gear 444 meshes with the drive gear 46 and the lifting gear 423 respectively, the rotation of the drive gear 46 will drive the lifting gear 423 to rotate in the forward direction, thereby causing the lifting plate 42 to rotate in the forward direction.

[0054] When the reversing frame 44 rotates to the point where the reverse gear 443 meshes with the drive gear 46 and the lifting gear 423 respectively, the drive gear 46 drives the lifting plate 42 to rotate in the opposite direction.

[0055] The reversing frame 44 has non-parallel opposing surfaces 441 and 442 on its side wall; the driving component 60 also includes a reversing part 65 that slides longitudinally on the receiving plate 61 and is driven by the gravity of the pallet assembly 5; a reversing groove 66 is provided on one side of the reversing part 65; two parallel and horizontally arranged opposing pressure surfaces 661 and 662 are provided in the reversing groove 66; a reversing spring is provided between the reversing part 65 and the receiving plate 61 to drive the reversing part 65 to return to its upward position.

[0056] When the upper end of the receiving plate 61 has the tray assembly 5, the tray assembly 5 presses down on the reversing part 65, so that the reversing part 65 is in the lower limit position, and the reverse pressing surface 661 is directly opposite the reverse abutting surface 441. At this time, the receiving plate 61 moves downward towards the finished product frame 41, the reverse pressing surface 661 will contact the reverse abutting surface 441 and force the reverse abutting surface 441 to move to the horizontal, and then the reversing frame 44 rotates, and the reverse gear 443 meshes with the driving gear 46 and the lifting gear 423 respectively.

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

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

[0059] The pick-and-place unit 2 includes a movable gripper 23 for holding the carbon brush holder assembly, a longitudinal electric rail 22 for driving the movable gripper 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; a visual inspection unit 18 for observing the current position of the carbon brush holder assembly is provided on one side of the movable gripper 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 leads are crooked, and whether the capacitor leads are inserted into the slot.

[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 crooked.

[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's insulating paper.

[0065] In the initial state, one finished product rack 41 does not contain a tray assembly 5, while another finished product rack 41 contains multiple tray assemblies 5. The pressing part 53 in the uppermost tray assembly 5 abuts against the top plate 412, and each deflection plate 56 is separated from the tray 51. None of the trays 51 contain a carbon brush holder assembly. The receiving plate 61 does not have a tray assembly 5, and the reversing part 65 is located at its upper limit position.

[0066] Before the equipment starts working, place a tray assembly 5 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 pallet assembly 5 until the receiving plate 61 moves directly below the pallet assembly 5. During this process, the forward pressing surface 662 contacts the forward abutting surface 442 and drives the reversing frame 44 to rotate. The forward gear 444 meshes with the drive gear 46 and the lifting gear 423 respectively. At the same time, the feed pawl 63 cooperates with the feed ratchet ring 451, causing the outer ring 45 to rotate and the spring to store power.

[0068] After the feed pawl 63 separates from the feed ratchet ring 451, the release pawl 64 contacts the release ratchet 49, and the release ratchet 49 rotates 180°. At this time, the receiving plate 61 moves to directly below the pallet assembly 5, the reversing slot 66 separates from the reversing frame 44, and the reversing frame 44 remains in its current state. At the same time, the release frame 48 cooperates with the limiting protrusion 461, and the drive 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° clockwise, the abutment column 421 rotates downwards, causing each tray assembly 5 to move downwards. The lowest tray assembly 5 is placed on the receiving plate 61, and the guide port 523 on the base 52 of the lowest tray assembly 5 slides into the guide column 62. Then, after passing below the pivot of the lifting plate 42, the abutment column 421 no longer contacts the limiting protrusion 461 and moves upwards. Finally, the abutment column 421 abuts against the two tray assemblies 5 that are not at the lowest position.

[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 pallet assembly 5 to leave the finished product rack 41.

[0071] When inspecting the carbon brush holder assembly, the feed guide 12 moves the carbon brush holder assembly 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 assembly onto the defective product conveyor belt 3, and sequentially places the qualified carbon brush holder assembly onto the tray 51 on the receiving plate 61.

[0073] Once 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, as follows.

[0074] At this point, the receiving plate 61 has a tray assembly 5, and the reversing part 65 moves to its lower limit position under the gravity of the tray assembly 5, with the reverse pressure surface 661 facing the reverse abutment surface 441. The electric slide rail 6 drives the receiving plate 61 to move towards another finished product rack 41 until the receiving plate 61 moves directly below the finished product rack 41. During this process, the reverse pressure surface 661 drives the reverse abutment surface 441 to move to a horizontal position, and the reversing frame 44 rotates. The reverse gear 443 meshes with the drive gear 46 and the lifting gear 423 respectively. At the same time, the feed pawl 63 drives the feed ratchet ring 451 to rotate, and the spring stores power.

[0075] Next, the release pawl 64 engages with the release ratchet 49, driving the release ratchet 49 to rotate 180°. At this time, the receiving plate 61 is directly below the finished product frame 41, the reversing slot 66 separates from the reversing frame 44, and the reversing frame 44 remains in its current state. Subsequently, as the release ratchet 49 rotates 180°, the release frame 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 pallet assembly 5 on the receiving plate 61 to move upward into the finished product rack 41, thereby completing the recycling of the pallet assembly 5.

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

[0078] Finally, all the tray assemblies 5 on one finished product rack 41 are removed, while the other finished product rack 41 is filled with tray assemblies 5, and the trays 51 within it are filled with carbon brush holder assemblies. Since the other finished product rack 41 is now full of tray assemblies 5, the pressing parts 65 in the uppermost tray assembly 5 abut against the top plate 412. The top plate 412 then drives each pressing part 65 to move downwards relative to the base 52, and the deflecting plates 56 no longer abut against the trays 51. At this point, the worker removes the trays 51 filled with carbon brush holder assemblies from the base 52 and places the empty trays 51 back onto the base 52. Thus, both finished product units 4 are restored to their initial state.
