Description

Technical Field

[0001] This utility model relates to the field of motor assembly equipment technology, and in particular discloses a carbon brush feeding mechanism and a carbon brush machine with position adjustment function. Background Technology

[0002] Existing carbon brush assembly equipment has significant defects in the feeding process: after being sorted by a vibratory feeder, the spring structure of the carbon brushes is prone to deflection during transport, resulting in inaccurate posture upon arrival at the transfer station. Traditional solutions rely on manual intervention or mechanical baffle correction, which is inefficient and cannot adapt to the pace of high-speed production lines. Some automated equipment attempts to add visual correction at the transfer station, but secondary positioning prolongs the cycle time, and vibration during carbon brush transfer can cause new posture deviations. Especially for miniature carbon brushes with bending springs, existing technology cannot correct the posture in real time during transfer, causing jamming of the assembly needle mechanism or misalignment of the carbon brush in the slot, resulting in a low yield rate. Utility Model Content

[0003] In order to overcome the technical problems of existing carbon brush assembly equipment, such as difficulty in real-time posture correction during transfer, resulting in jamming of the assembly needle mechanism or misalignment of the carbon brush in the slot and low yield, the purpose of this utility model is to provide a carbon brush feeding mechanism and carbon brush machine with position adjustment function to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model provides a carbon brush feeding mechanism with a position adjustment function, comprising a picking robot, a detection unit used in conjunction with the picking robot, and a control unit. The picking robot includes a picking clamp, a first drive module and a second drive module respectively connected in conjunction with the picking clamp. The first drive module is used to drive the picking clamp to move between the feeding mechanism and the transfer mechanism of the external carbon brush machine and to pick up and place carbon brushes. The second drive module is used to drive the picking clamp to rotate. The control unit is electrically connected to the detection unit, the first drive module and the second drive module. The detection unit is used to detect the posture information of the carbon brush picked up by the picking clamp and transmit it to the control unit. The control unit is used to adjust the posture of the carbon brush by the second drive module according to the posture information before the picking clamp moves to the external transfer mechanism, and to control the first drive module to transfer the external carbon brush adjusted to the preset posture to the transfer mechanism of the external carbon brush machine.

[0005] The detection unit, electrically coupled with the second drive module, is used to detect the attitude data of the carbon brush picked up by the pick-up clamp relative to the external transfer platform. The detection unit uploads the detected attitude data to the control unit. The control unit compares the attitude data with the attitude data required by the built-in transfer platform. When the attitude data of the carbon brush picked up by the pick-up clamp matches the attitude data required by the transfer platform, the control unit controls the first drive module to drive the pick-up clamp to move the carbon brush to the external transfer platform. When the attitude data of the carbon brush picked up by the pick-up clamp does not match the attitude data required by the transfer platform, the control unit controls the second drive module to drive the pick-up clamp to rotate and adjust the carbon brush to the required position on the transfer platform, and controls the first drive module to move the carbon brush adjusted to the required position to the transfer platform.

[0006] Furthermore, the first drive module includes a first support member, a first movable member reciprocatingly mounted on the first support member, and a first drive member for driving the first movable member to reciprocate; the first support member is used to be mounted on an external frame, and the first drive module also includes a second movable member reciprocatingly mounted on the first movable member, a second drive member for driving the second movable member to reciprocate, and a third drive member mounted on the second movable member; the movement direction of the first movable member and the movement direction of the second movable member are intersecting each other, and the material picker is located at the output end of the third drive member, and the third drive member is used to drive the material picker to pick up and put down carbon brushes.

[0007] Furthermore, the third driving component is a gripper cylinder, and the gripper includes two parallel fingers that are relatively movably disposed at the output end of the gripper cylinder. The gripper cylinder is used to drive the two parallel fingers to move closer or further away to grip or release the carbon brush.

[0008] Furthermore, the first drive module also includes a first slide rail slider assembly and a second slide rail slider assembly. The first moving member is slidably mounted on the first support member via the first slide rail slider assembly, and the second moving member is slidably mounted on the first moving member via the second slide rail slider assembly.

[0009] Furthermore, the second drive module includes a fourth drive component and a rotating component connected to the output end of the fourth drive component. The rotating component is disposed on the second moving component. The third drive component is connected to the rotating component. The fourth drive component is used to drive the rotating component to rotate so that the third drive component rotates in conjunction with the material handling clamp.

[0010] Furthermore, the rotating assembly includes a mounting base disposed on the second moving member, a shaft disposed on the mounting base, and a gear disposed on the shaft; the fourth driving member includes a feeding cylinder and a gear condition disposed at the output end of the feeding cylinder, the gear is meshed with the gear condition for transmission, the fourth driving member is used to drive the gear condition to reciprocate and drive the shaft to rotate via the gear, and the free end of the third driving member is connected to the shaft.

[0011] Furthermore, the second drive module also includes a rotation limiting member, which is disposed at the end of the shaft component away from the material picker. The rotation limiting member has a stop portion, the extension direction of which is intersected with the extension direction of the rotation axis of the shaft component. The maximum rotation radius m of the stop portion around the shaft component is less than the closest distance n between the central axis of the shaft component and the second moving component.

[0012] Furthermore, the first drive module also includes a first limiting member and a second limiting member disposed at both ends of the movement direction of the second moving member, and the second drive member is used to drive the second moving member to move between the first limiting member and the second limiting member.

[0013] Furthermore, a first mounting plate is provided on one side of the material handling clamp, and the detection unit includes a laser displacement sensor detachably mounted on the first mounting plate. The laser emission direction of the laser displacement sensor is parallel to the opening and closing direction of the material handling clamp, and the center of the laser spot of the laser displacement sensor is aligned with the central axis of the material handling clamp.

[0014] This utility model discloses a carbon brush machine, comprising a feeding mechanism, a sorting mechanism, a transfer mechanism, a stator limiting mechanism, and an assembly mechanism. The carbon brush machine further includes a carbon brush feeding mechanism with position adjustment function. The feeding mechanism sorts multiple external carbon brushes and arranges them in a first posture before conveying them to the sorting mechanism. The sorting mechanism separates the multiple external carbon brushes conveyed by the feeding mechanism into individual carbon brushes. The control unit of the carbon brush feeding mechanism with position adjustment function coordinates the first drive module, the second drive module, and the detection unit to pick up the individual carbon brushes and adjust them to a preset posture before conveying them to the transfer mechanism. The external stator is fixed by the stator limiting mechanism. The transfer mechanism includes a picking component and a pressing pin assembly used in conjunction with the picking component. The picking component picks up the carbon brushes in the preset posture and transfers them to the assembly mechanism. The pressing pin assembly abuts against the carbon brushes in the preset posture, pressing them into the assembly mechanism. The assembly mechanism presses the carbon brushes pressed in by the pressing pin assembly into the external stator fixed by the stator limiting mechanism.

[0015] The beneficial effects of this invention are as follows: This invention achieves in-situ posture correction of the carbon brush throughout the entire process from gripping to placement, eliminating the cycle time loss of traditional secondary positioning and further improving assembly efficiency; the closed-loop control of laser detection and rotation compensation improves the alignment accuracy of the carbon brush posture and solves the problem of press-fit jamming caused by spring interference; the modular design adapts to carbon brushes of different sizes, and is especially suitable for high-speed assembly of carbon brushes for micro motors. Meanwhile, the hard-limit design of the rotation limit block and limit baffle eliminates the risk of over-adjustment and ensures the stability of continuous equipment operation.

[0018] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0019] Please see Figures 1 to 6 As shown, this utility model discloses a carbon brush feeding mechanism with position adjustment function, comprising a picking robot 1, a detection unit 2, and a control unit. The picking robot 1 is integrally mounted on the frame of an external carbon brush machine and fixed to the frame by a first support member 41. The core component of the picking robot 1 is the picking clamp 3, which is located at the end of the entire mechanism and is used to directly clamp the carbon brush. The picking clamp 3 is connected to a first drive module 4 and a second drive module 5, respectively. The first drive module 4 is responsible for the translational movement of the picking clamp 3, enabling the picking clamp 3 to move along multiple axes (X-axis and Y-axis in this embodiment) between the feeding mechanism 100 and the transfer mechanism 300 of the carbon brush machine; the second drive module 5 is responsible for the rotational movement of the picking clamp 3, enabling the clamped carbon brush to adjust its posture as needed during the transfer process.

[0020] Specifically, the detection unit 2 is fixed on one side of the material handling clamp 3, preferably a laser displacement sensor 21, which is mounted on a detachable first mounting plate 32. The first mounting plate 32 is screwed or pinned to one of the parallel fingers 31. The laser emission direction of the laser displacement sensor 21 is parallel to the opening and closing direction of the parallel fingers 31 of the material handling clamp 3, and the center of the laser spot is precisely aligned with the central axis of the material handling clamp 3 to ensure the accuracy of posture information acquisition.

[0021] Specifically, the detection unit 2 is electrically connected to the control unit via signal lines or a bus. The control unit is connected to both the first drive module 4 and the second drive module 5 via cables and solenoid valves, enabling motion control of the two drive modules. Compared to existing technologies, this structure highly integrates movement, rotation, and detection functions into the same robotic arm unit, allowing posture adjustment and transfer to be completed synchronously within the same stroke, reducing additional workstations and cycle time losses.

[0022] Specifically, the first drive module 4 includes a first support member 41, a first moving member 42, a first drive member 43, a second moving member 44, a second drive member 45, and a third drive member 46. The first support member 41 is an integral profile bracket, made of rectangular cross-section aluminum profile or welded steel plate, rigidly mounted on the frame. The first moving member 42 is slidably connected to the first support member 41 via a first slide rail slider assembly 47, which is a precision linear guide rail, ensuring that the first moving member 42 moves smoothly along a first direction (e.g., the horizontal X-axis).

[0023] The first driving component 43 is preferably a cylinder, mounted on the first supporting component 41, with its piston rod fixedly connected to the first moving component 42, driving the first moving component 42 to reciprocate in the X-axis direction. The second moving component 44 is mounted on the first moving component 42 via a second slide rail slider assembly 48, the sliding direction of the second slide rail slider assembly 48 being perpendicular to the first slide rail slider assembly 47 (Y-axis direction). The second driving component 45 is preferably a cylinder, mounted on the first moving component 42, with its piston rod fixedly connected to the second moving component 44, driving the second moving component 44 to reciprocate along the Y-axis direction.

[0024] The third drive unit 46 is mounted on the mounting base 521 of the second moving unit 44, and its output end is connected to the pick-up clamp 3. The third drive unit 46 is preferably a gripper cylinder, which drives two parallel fingers 31 to move relative to each other to clamp and release the carbon brushes. Through the combined control of the first drive unit 43 and the second drive unit 45, the pick-up clamp 3 can cover the loading position and the transfer position in the X and Y planes, achieving precise pick-up and drop of carbon brushes. Compared with the prior art, this multi-axis combined translational structure can cover a larger working range in a limited installation space, reduce additional handling mechanisms, and improve the overall layout compactness.

[0025] Specifically, the second drive module 5 is used for the rotational adjustment of the material handling clamp 3, and mainly includes a fourth drive component 51, a rotating assembly 52, and a third drive component 46 that cooperates with the rotating assembly 52. ​​The rotating assembly 52 is mounted on the second moving component 44 and includes a mounting base 521, a shaft component 522, and a gear component 523 mounted on the shaft component 522. The shaft component 522 is mounted on the mounting base 521 by bearings and can rotate around its own axis. The third drive component 46 is coaxially fixed to the shaft component 522 by a flange or positioning sleeve, thereby driving the entire material handling clamp 3 to rotate when the shaft component 522 rotates.

[0026] The fourth driving component 51 is preferably a cylinder, with a rack fixed to the end of its piston rod. The rack meshes with a gear 523 on the shaft component 522. When the fourth driving component 51 drives the rack to perform linear reciprocating motion, it drives the gear 523 and the shaft component 522 to rotate. To prevent excessive rotation, a rotation limiting component 53 is provided at the other end of the shaft component 522. The limiting component includes a stop portion 531, which extends in a direction perpendicular to the axis of the shaft component 522. Its rotation radius is smaller than the closest distance between the central axis of the shaft component 522 and the second moving component 44, to ensure that the rotation range is controlled and does not interfere with surrounding components.

[0027] Compared to existing technologies, this rack and pinion transmission combined with cylinder-driven rotation has a compact structure, high transmission efficiency, and the rotation angle can be precisely set through the cylinder stroke, enabling rapid adjustment of the carbon brush posture without the need for a complex servo system.

[0028] Specifically, the detection unit 2 is a laser displacement sensor 21, mounted on the first mounting plate 32 on one side of the pick-up clamp 3. This sensor can detect the posture information of the carbon brush held by the pick-up clamp 3 in real time, including the relative direction of the carbon brush contact block and the spring. The detected information is transmitted to the control unit in the form of a digital signal. The control unit compares the detected posture with the standard posture required by the transfer mechanism 300. When the detection result shows that the posture is consistent, the control unit directly issues a command to drive the first drive module 4 to move the carbon brush to the transfer mechanism 300; when the detection result shows that the posture is inconsistent, the control unit first controls the fourth drive component 51 to rotate the pick-up clamp 3 to the standard posture, and then controls the first drive module 4 to move the carbon brush to the transfer mechanism 300.

[0029] The entire inspection and adjustment process is completed while the pick-up clamp 3 is moving from the loading position to the transfer position, without adding any extra cycle time. Compared with existing technologies, this method of moving and adjusting simultaneously avoids the need to set up a separate attitude correction station, significantly shortens the production cycle time, and reduces the risk of secondary attitude deviation of the carbon brush during the transfer process.

[0030] Specifically, in terms of workflow, the operation steps of this mechanism are as follows: the first drive module 4 controls the material picker 3 to move to the position of the feeding mechanism 100, and the third drive component 46 drives the material picker 3 to clamp a single carbon brush; the laser displacement sensor 21 detects the posture information of the clamped carbon brush and transmits it to the control unit; the control unit determines whether posture adjustment is required, and if so, controls the second drive module 5 to rotate and adjust. After the adjustment is completed, the first drive module 4 continues to drive the material picker 3 to move to the position of the transfer mechanism 300; after it is in place, the third drive component 46 releases the parallel finger 31 to release the carbon brush to the transfer mechanism 300 of the external carbon brush machine, and the material picker component 301 of the transfer mechanism 300 takes over and sends it into the assembly mechanism 500 to complete the subsequent pressing.

[0031] Throughout the process, the multi-axis movement of the first drive module 4 and the rotation of the second drive module 5 can be executed in an overlapping manner, improving cycle efficiency. Compared with existing technologies, this control strategy integrates detection, adjustment, and transfer into a continuous action sequence, reducing waiting time and idle travel, and improving the overall production efficiency and carbon brush feeding consistency.

[0032] This utility model discloses a carbon brush machine, comprising a feeding mechanism 100, a dispensing mechanism 200, a transfer mechanism 300, a stator limiting mechanism 400, and an assembly mechanism 500. It also includes a carbon brush feeding mechanism with position adjustment function mounted on one side of the frame. The feeding mechanism 100 is a vibratory feeder or linear feeding structure, with its outlet end connected to the inlet of the dispensing mechanism 200. The feeding mechanism 100 sorts multiple external carbon brushes via a spiral track, arranging them in a first orientation (carbon brush contact blocks facing downwards or in the same direction) and conveying them to the dispensing mechanism 200. The dispensing mechanism 200 uses a pusher-plate or sliding plate separation device to sequentially separate the multiple carbon brushes conveyed by the feeding mechanism 100 into individual carbon brushes, and then sends the individual carbon brushes to the picking position of the carbon brush feeding mechanism.

[0033] The carbon brush feeding mechanism includes a picking robot 1, a detection unit 2, and a control unit mounted on a fixed bracket of the frame. The picking robot 1 has a picking clamp 3 at its end, which is driven by a third drive component 46 to clamp or release the carbon brushes. In this embodiment, the third drive component 46 is a gripper cylinder controlled by an air source and a solenoid valve. The picking clamp 3 is mounted at the front end of a second moving component 44, which can move along the Y-axis and is driven by a second drive component 45, a double-acting cylinder mounted on a first moving component 42. The first moving component 42 moves along the X-axis and is driven by a first drive component 43, also a double-acting cylinder mounted on a first support component 41.

[0034] The first support member 41 is bolted to the column of the frame and guided to linear motion by the first slide rail slider assembly 47. The second moving member 44 is guided to linear motion by the second slide rail slider assembly 48. A second drive module 5 is also mounted on the second moving member 44. The second drive module 5 includes a fourth drive member 51 and a rotating assembly 52. ​​The fourth drive member 51 is a double-acting cylinder with a rack fixed to the end of its piston rod. The rack meshes with a gear 523 mounted on a shaft member 522. The shaft member 522 is supported on a mounting base 521 by bearings, and the mounting base 521 is fixedly connected to the second moving member 44. The third drive member 46 is coaxially mounted with the shaft member 522. Therefore, when the shaft member 522 rotates, it drives the material picker 3 to rotate, achieving carbon brush posture adjustment.

[0035] In this embodiment, the detection unit 2 is a laser displacement sensor 21, mounted on a first mounting plate 32 on one side of the second moving member 44. The mounting plate is fixedly connected to the second moving member 44 by screws. The laser emission direction of the sensor is parallel to the opening and closing direction of the parallel fingers 31 of the pick-up clamp 3, and the center of the laser spot is aligned with the central axis of the pick-up clamp 3 to accurately detect the positional relationship between the contact block and the spring when the carbon brush is clamped. The detection unit 2 is connected to the control unit through a shielded signal line, and the output attitude signal is a digital quantity to meet the detection requirements of high-speed feeding.

[0036] The control unit is a PLC (Programmable Logic Controller), installed in the electrical control cabinet of the carbon brush machine. The PLC has built-in multiple digital input / output interfaces and analog input interfaces. The digital signals of the detection unit 2 are acquired through the high-speed input terminal of the PLC. The solenoid valves of the first drive unit 43, the second drive unit 45, the third drive unit 46, and the fourth drive unit 51 are respectively connected to the digital output ports of the PLC, and the cylinder action is controlled through intermediate relays.

[0037] The PLC program logic is as follows: When the positioning sensor of the feeding mechanism 200 sends a single carbon brush positioning signal, the PLC outputs a signal to drive the solenoid valve of the third driving component 46 to open, and the gripper cylinder closes to clamp the carbon brush; after clamping, the detection unit 2 is immediately triggered to collect posture data and send the data to the PLC comparison unit for comparison with the pre-stored standard posture data; if the comparison results are consistent, the PLC directly outputs a signal to drive the solenoid valves of the first driving component 43 and the second driving component 45, controlling the first moving component 42 and the second moving component 44 to cooperate and move the picking clamp 3 along with the carbon brush to the feeding position of the transfer mechanism 300; if the comparison results are inconsistent, the PLC first outputs a signal to drive the solenoid valve of the fourth driving component 51, controlling the gear condition 512 to drive the gear component 523 and the shaft component 522 to rotate, adjusting the carbon brush posture to the standard position, and then controlling the first driving component 43 and the second driving component 45 to send the carbon brush to the transfer mechanism 300. Upon reaching the transfer mechanism 300, the PLC outputs a signal to drive the solenoid valve of the third drive component 46 to reverse, causing the gripper cylinder to open and release the carbon brush, which is then taken over by the material handling component 301 of the transfer mechanism 300.

[0038] The transfer mechanism 300 includes a picking assembly 301 and a pressing needle assembly 302 mounted on the frame. The picking assembly 301 is guided by a linear slide rail and drives the picking clamp 3 to descend to the carbon brush position along the Z-axis (vertical direction) to pick up the carbon brush and deliver it to the pressing position of the assembly mechanism 500. The pressing needle assembly 302 is mounted above the assembly mechanism 500 and is driven by a servo motor-driven lead screw or a cylinder. The pressing needle moves downward along the Z-axis, pressing against the contact block of the carbon brush, so that the spring end of the carbon brush is accurately inserted into the stator slot fixed in the stator limiting mechanism 400. The stator limiting mechanism 400 is a fixture with a positioning pin and a clamping device, used to fix the stator to prevent movement during the pressing process. After the carbon brush pressing is completed, the assembly mechanism 500 lifts the pressing needle and releases the stator, completing one cycle.

[0039] In this embodiment, the control unit uses program control to establish interlocking logic among the first drive component 43, the second drive component 45, the third drive component 46, and the fourth drive component 51. This prevents attitude adjustment from being initiated before the gripper is fully closed, or prevents translational transfer from being initiated before attitude adjustment is completed, thereby avoiding carbon brush drop or attitude deviation. All drive cylinders are equipped with limit switches, and the limit switch signals are connected to the PLC for real-time monitoring of the position status of each drive component, ensuring safe and reliable operation.

[0040] Compared to existing technologies, the carbon brush machine in this embodiment integrates carbon brush picking, posture detection, posture adjustment, and translation into a single carbon brush feeding mechanism. The electrical coordination between the control unit, detection unit 2, and each driving component is clearly defined, and the signal acquisition and motion control operate in a closed loop, ensuring the posture consistency of the carbon brushes during high-speed production. This reduces the need for additional posture correction stations, significantly improves production cycle time and assembly yield, and simplifies the overall machine layout while reducing maintenance costs.

[0041] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
