Description

Technical Field

[0001] This invention relates to the field of conductive slip ring manufacturing technology, and more specifically, to an integrated device for detecting the bending of conductive slip ring brush filaments. Background Technology

[0002] As a core component in spacecraft, the performance of conductive slip rings directly determines the stability and reliability of the system. Among these, angle control during the bristle bending process is crucial to the stability and lifespan of the slip ring. Current manufacturing processes for conductive slip rings suffer from poor process consistency and low efficiency due to manual bending. Therefore, it is necessary to develop automated bending and inspection devices for conductive slip rings to improve the consistency of bristle bending and increase manufacturing efficiency.

[0003] Patent document CN110492331B discloses a conductive slip ring brush filament forming device, which achieves controllable brush filament angle forming through a rotary table and a displacement guide rail. However, its disadvantages are that it can only achieve segmented bending of brush filaments on one side, and cannot perform simultaneous bending on both sides, resulting in low brush filament bending efficiency and low consistency of brush filament bending on both sides of the brush filament assembly.

[0004] Patent document CN219535142U discloses a conductive slip ring brush filament angle forming device, which uses manual rotation of a handle to drive a cam to press and fix the brush filaments by pressing a clamping plate. However, its disadvantages are that it lacks multi-module series connection and automatic transmission, and processing and inspection cannot be connected in series, which requires increasing the number of clamping and disassembly operations, resulting in low processing efficiency and accuracy.

[0005] Patent document CN117895304B discloses an integrated device and method for conductive slip ring brush bristle forming and deformation detection. It uses a bristle angle forming unit to ensure high consistency in bristle forming, and a bristle deformation detection unit to measure and monitor the bristle deformation. However, its drawback is the lack of a bristle cutting module, making it unable to process bristle assemblies with inconsistent initial bristle lengths, resulting in low processing adaptability.

[0021] As shown in the figure: Detailed Implementation

[0022] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0023] This invention proposes an integrated device for detecting the bending of conductive slip ring brush filaments. Figures 1 to 8 One embodiment is shown.

[0024] Figure 1 A general schematic diagram of the integrated conductive slip ring brush filament bending detection device according to an embodiment of the present invention is shown. The integrated conductive slip ring brush filament bending detection device of the present invention mainly includes an optical platform base plate 1, a linear motion platform 2, a filament cutting module 3, a bending module 4, a pressure detection module 5, and a vision inspection module 6. The optical platform base plate 1 has a first direction, a second direction, and a third direction that are perpendicular to each other. The first direction can be the length direction, the second direction can be the width direction, and the third direction can be the height direction.

[0025] A linear motion platform 2 is fixed on an optical platform base plate 1. A filament cutting module 3, a bending module 4, a pressure detection module 5, and a vision inspection module 6 are sequentially mounted on the optical platform base plate, and also located above the linear motion platform 2. The linear motion platform 2 drives the brush filament assembly 7 to move between different stations: at the filament cutting station, the filament cutting module 3 cuts the brush filaments 72 of the brush assembly 7 to a specified length; at the bending station, the bending module 4 bends the brush filaments 72; at the pressure detection station, the pressure detection module 5 detects the simulated ring brush contact pressure of the bent brush filaments 72; at the vision inspection station, the vision inspection module 6 detects the bending angle of the brush filaments 72. This invention integrates the brush filament forming and detection modules into a single device, combining filament cutting, bending, pressure detection, and vision inspection into one unit, achieving efficient and high-precision manufacturing of the brush filament assembly 7, and providing a solution for the manufacturing of long-life, high-reliability conductive slip rings.

[0026] like Figure 2 As shown, the linear motion platform 2 includes a linear slide 21 and a loading platform 22. The linear slide 21 includes a linear slide guide rail 211, a left linear slide baffle 212, a right linear slide baffle 213, a linear slide limit block 214, a linear slide stepper motor 215, a linear slide coupling 216, a linear slide slider 217, and a linear slide ball screw 218.

[0027] The linear slide rail 211 can be fixedly mounted on the optical platform base plate 1 using aluminum profile corner fittings, serving as both the base of the linear slide 21 and a guide rail for the linear slide slider 217. The extension direction of the linear slide rail 211 is parallel to the first direction of the optical platform base plate 1. The left baffle 212 and the right baffle 213 of the linear slide are fixedly disposed at both ends of the linear slide rail 211. The linear slide limiting block 214 is disposed between the left baffle 212 and the right baffle 213 of the linear slide, and can be closer to the right baffle 213. All three are securely connected to the linear slide rail 211.

[0028] A linear slide stepper motor 215 is securely connected to the right baffle 213 of the linear slide. The first end of the linear slide ball screw 218 is rotatably connected to the left baffle 212 of the linear slide via a bearing, and the second end extends towards the right baffle 213 and is rotatably connected to the linear slide limit block 214 via a bearing. A linear slide coupling 216 connects the second end of the linear slide ball screw 218 to the output shaft of the linear slide stepper motor 215, causing the output shaft of the linear slide stepper motor 215 to drive the linear slide ball screw 218 to rotate. A linear slide slider 217 is slidably connected to the linear slide guide rail 211, which restricts the rotation direction of the linear slide slider 217, allowing it to move only in a first direction parallel to the optical platform base plate 1. The linear slide stepper motor 215 drives the linear slide ball screw 218 to rotate, thereby driving the linear slide slider 217 to move linearly. The linear slide block 217 has an opening at the top, which is fastened to the loading platform 22, driving the loading platform 22 to move synchronously along the linear slide guide rail 211, thereby driving the brush assembly 7 to reciprocate between modules along the first direction.

[0029] The linear motion platform 2 can be controlled by a precision controller to move accurately in the first direction of the optical platform base plate 1, ensuring the precise position of the brush assembly 7. At the same time, as the core serial structure, the linear motion platform 2 can connect functional modules such as wire cutting, bending, pressure detection, and vision inspection, and work with computer programs to drive each module to automatically perform processing and inspection. It also collects detection data through sensors, realizing an integrated automated manufacturing process for the brush assembly 7 from processing to inspection.

[0030] like Figure 3As shown, the loading platform 22 includes a loading platform base plate 221, a positioning block 222, a clamp 223, an electric push rod 224, a bending rod fastener 225, and a bending rod 226. The positioning block 222, clamp 223, and electric push rod 224 are fastened to the loading platform base plate 221. The positioning block 222 specifically abuts against the side of the brush bristle assembly 7 along the second direction, precisely determining the installation position of the brush bristle assembly 7 on the loading platform 22 through this side abutment, avoiding accuracy errors caused by positional deviation of the brush bristles 72 during subsequent processing. The clamp 223 clamps the brush bristle plates 71 from both sides of the brush bristle assembly 7, further securing the brush bristle assembly 7. The positioning block 222 can be replaced with different sizes to accommodate brush bristle assemblies 7 of different volumes, meeting the manufacturing needs of multiple specifications of brush bristle assemblies 7.

[0031] Two sets of electric actuators 224 are provided, located on both sides of the brush assembly 7 in the second direction of the optical platform base plate 1, with the extended ends of the two sets of electric actuators 224 facing each other. A bending rod fastener 225 is securely connected to a hole at the front end of the electric actuator 224. The bending rod 226 and the bending rod fastener 225 are interference-fitted. The opening at the front end of the bending rod fastener 225 is clamped by a screw to prevent the bending rod 226 from slipping. Simultaneously, the stroke and installation height of the electric actuators 224 are precisely calibrated to ensure that the bending rod 226, fixed at its extended end, is precisely aligned with the connection point between the brush filament 72 and the brush filament plate 71 in the third direction, providing a precise force support point for subsequent bending of the brush filament 72 in conjunction with the bending module 4.

[0032] When the brush filament assembly 7 is mounted on the loading platform 22, the brush filaments 72 are arranged in two columns along the first direction of the optical platform base plate 1, and these two columns of brush filaments 72 are arranged along the second direction, that is, one column is located on the left side of the second direction and the other column is located on the right side of the second direction, with each column of brush filaments 72 arranged sequentially along the first direction. At the same time, the brush filaments 72 of the brush filament assembly 7 are arranged in multiple groups along the first direction, with each group having two brush filaments 72 aligned along the second direction.

[0033] like Figure 4 As shown, the wire cutting module 3 includes a wire cutting module fixing column 31, a wire cutting module fixing plate 32, a horizontal moving module 33, a vertical moving module 34, a wire cutting pliers fixing bracket 35, and wire cutting pliers 36.

[0034] The wire cutting module fixing posts 31 are fixedly installed on both sides of the linear moving platform 2 in the second direction of the optical platform base plate 1, and the wire cutting module fixing plate 32 is fixedly connected to the top of the wire cutting module fixing posts 31. The bottom end of the wire cutting module fixing posts 31 can be provided with threaded posts of the same diameter as the holes in the optical platform base plate 1 to achieve a stable connection. The wire cutting module fixing plate 32 can be made of carbon fiber plate, with holes for connecting the wire cutting module fixing posts 31. Simultaneously, a horizontal moving module 33 can be fixedly installed on the wire cutting module fixing plate 32, and a vertical moving module 34 is fastened to the slide of the horizontal moving module 33 and moves synchronously with the horizontal moving module 33. The moving direction of the horizontal moving module 33 is parallel to the second direction of the optical platform base plate 1.

[0035] The wire cutter fixing bracket 35 can be fixedly connected to the slide of the vertical moving module 34, and the handle of the wire cutter 36 is fixedly installed on the wire cutter fixing bracket 35. The moving direction of the vertical moving module 34 is parallel to the third direction of the optical platform base plate 1. The opening and closing direction of the wire cutter 36 is parallel to the first direction, which facilitates cutting the brush filaments 72 from the cross-sectional direction. The wire cutter driving module drives the wire cutter 36 to reciprocate along the second and third directions through the coordinated action of the horizontal moving module 33 and the vertical moving module 34: when it is necessary to cut different columns of brush filaments 72, the horizontal moving module 33 drives the wire cutter 36 to move along the second direction, switching to align with the left or right column of brush filaments 72. When it is necessary to adjust the cutting length of the brush filaments 72, the vertical moving module 34 drives the wire cutter 36 to move along the third direction, aligning with the different length positions on the brush filaments 72 that need to be cut, thereby accurately controlling the cutting length of the brush filaments 72 and adapting to different specification requirements.

[0036] like Figure 5 As shown, the bending module 4 includes a bending module fixing post 401, a bending module fixing plate 402, a bending module stepper motor 403, a bending module support plate 404, a detachable base 405, a bending module coupling 406, a bending module ball screw 407, a ball screw base frame 408, a bending module guide rail 409, a bending module slider 410, a slider connecting plate 411, a connecting rod connecting plate 412, a first connecting rod 413, a second connecting rod 414, a third connecting rod 415, and a fourth connecting rod 416. The bending module fixing post 401 is fixedly installed on both sides of the linear moving platform 2 in the second direction, and the bending module fixing plate 402 is fixedly installed on the top of the bending module fixing post 401. The bottom of the bending module fixing post 401 can be provided with a threaded post with the same hole diameter as the optical platform base plate 1 to achieve a stable connection. The bending module fixing plate 402 can be made of carbon fiber plate, with holes on the plate for fixed connection to the bending module fixing post 401. The bending module fixing plate 402 can be equipped with a bending module stepper motor 403 at the top. The bending module fixing plate 402 has a central hole so that the output shaft of the bending module stepper motor 403 extends downward to the bottom of the bending module fixing plate 402.

[0037] The bending module support plate 404 can be made of stainless steel. Its first end is securely connected to the bottom of the bending module fixing plate 402, and its second end extends away from the bending module fixing plate 402, with a detachable base 405 at the second end. Two bending module guide rails 409 can be fixedly mounted on the bending module support plate 404, spaced vertically, with their guide planes higher than the surface of the bending module fixing plate 402. A channel is formed between the two bending module guide rails 409. A bending module ball screw 407 is positioned parallel to the guide rails within this channel. Its first end is connected to the output shaft of the bending module stepper motor 403 via a bending module coupling 406, and its second end is rotatably connected to the screw base 408 via a bearing. The screw base 408 provides axial and radial support for the ball screw.

[0038] The slider connecting plate 411 is fastened to the bending module slider 410. The bending module slider 410 is screwed to the bending module ball screw 407 and engages with the bending module guide rail 409 to form a sliding connection, restricting the degree of rotational freedom. When the bending module stepper motor 403 drives the ball screw to rotate, it drives the bending module slider 410, along with the slider connecting plate 411, to move synchronously in a straight line along the axis of the bending module ball screw 407.

[0039] The upper part of the connecting plate 412 is connected to the slider connecting plate 411, and the lower part has a circular hole with a metal pin fixedly connected to it. The metal pin is coaxially rotatably connected to the first end of the first connecting rod 413 and the second connecting rod 414. The second end of the first connecting rod 413 is rotatably connected to the first end of the third connecting rod 415, and the second end of the second connecting rod 414 is rotatably connected to the first end of the fourth connecting rod 416. The first connecting rod 413 and the second connecting rod 414 are of the same length, and the third connecting rod 415 and the fourth connecting rod 416 are of the same length. The second ends of the third connecting rod 415 and the fourth connecting rod 416 are rotatably connected to two through holes in the detachable base 405, respectively.

[0040] The third link 415 and the fourth link 416 are arranged along the second direction of the optical platform base plate 1, and each has an initial position and a bending position. In the initial position, they are parallel to the third direction, and the distance between them is less than the distance between the two rows of brush filaments 72, ensuring that when the brush filament assembly 7 moves, the two rows of brush filaments 72 can correspond to the outer sides of the third and fourth links respectively. When the bending module slider 410 moves away from the bending module fixing plate 402 along the bending module ball screw 407, the third link 415 and the fourth link 416 are converted from the initial position to the bending position through the transmission of the first link 413 and the second link 414. During the conversion, they are symmetrically and synchronously tilted outward along the second direction, cooperating with the bending rod 226 on the loading platform 22. The bending rod 226 abuts against the inner side of the brush filament 72, and the third link 415 and the fourth link 416 push the inner side of the brush filament 72 outward in the second direction, thus achieving the bending of the brush filament 72.

[0041] Simultaneously, the bending module lead screw module precisely controls the movement distance of the bending module slider 410, driving the third link 415 and the fourth link 416 to rotate to a preset bending angle. This preset bending angle is calculated in advance based on the material and diameter of the brush bristles 72, reserving springback allowance after bending to ensure that the final actual bending angle of the brush bristles 72 meets the design requirements. During the bending process, the loading platform 22 is driven to move along the first direction by the linear slide 21, realizing the relative movement between the loading platform 22 and the bending module 4. This allows different groups of brush bristles 72 arranged along the first direction to align one by one with the third and fourth links in their initial state, completing a cycle of bending one group, resetting the link, aligning the next group, and then bending again, until all groups of brush bristles 72 are bent.

[0042] like Figure 6 As shown, the pressure detection module 5 is fixedly installed on the optical platform base plate 1, located above the linear motion platform 2, and includes a pressure detection module fixing column 51, a pressure detection module fixing plate 52, a servo motor fixing bracket 53, a servo motor 54, a pressure sensor fixing bracket 55, a pressure sensor 56, and a pressure sensor contact 57.

[0043] Pressure detection module mounting posts 51 are distributed on both sides of the linear motion platform 2 in the second direction. The lower end has threaded posts that are securely connected to the optical platform base plate 1, supporting the pressure detection module mounting plate 52. The mounting plate 52 can be made of acrylic sheet, with holes for connecting the top of the mounting posts. A servo motor mounting bracket 53 is fixedly mounted in the center. The servo motor 54 is securely connected to the servo motor mounting bracket 53 and suspended at the bottom of the mounting plate 52. Its rotation axis is parallel to the first direction, ensuring that the rotation plane of the pressure sensor contact 57 is perpendicular to the first direction. The pressure sensor mounting bracket 55 is fixedly mounted on the servo disk of the servo motor 54. The pressure sensor 56 is fixed on the bracket 55, and the pressure sensor contact 57 is fixedly mounted at the bottom. The bottom of the contact 57 is arc-shaped, with the arc curvature equal to the curvature of the arc surface where the conductive ring contacts the brush bristles. A groove in the middle guides the brush bristles 72 to remain within the contact.

[0044] During testing, the linear motion platform 2 moves the brush bristle assembly 7 below the pressure detection module 5, aligning a set of brush bristles 72 with the pressure sensor contact 57 in the first direction. Then, the servo motor 54 rotates to the left in the second direction, moving the pressure sensor contact 57 closer to the left column of brush bristles 72 until the pressure sensor contact 57 is tangent to the bent section of the left brush bristle 72. At this point, the pressure sensor 56 detects and outputs the simulated ring brush contact pressure data of the left brush bristle. Next, the servo motor 54 rotates to the right in the second direction, similarly aligning the pressure sensor contact 57 with the bent section of the right column of brush bristles 72, detecting and outputting the pressure data of the right brush bristle. After completing one set of tests, the servo motor 54 returns to its initial angle, i.e., the pressure sensor contact 57 is parallel to the third direction and vertically downwards. The loading platform 22 moves to the next set of brush bristles 72, repeating the above operation until all sets of brush bristles 72 have been tested.

[0045] The pressure sensor contact 57 can be replaced with different sizes to simulate the brush contact pressure on conductive rings of different diameters, thereby improving the device's adaptability to conductive slip rings of different specifications.

[0046] like Figure 7 As shown, the visual inspection module 6 is fixedly installed on the optical platform base plate 1 and located on both sides of the linear motion platform 2. It includes multiple sets of cameras (e.g., left camera 613 and right camera 623) and multiple sets of light sources (e.g., left light source 616 and right light source 626). The left camera 613 and left light source 616 are arranged on the left side of the linear motion platform 2 in the second direction, and the right camera 623 and right light source 626 are arranged on the right side of the linear motion platform 2 in the second direction, forming a "two-sided corresponding" inspection structure.

[0047] The bottom end of the left camera mounting post 611 is fastened to the left side of the optical platform base plate 1 via a threaded post, supporting the left camera mounting plate 612. The left camera mounting plate 612 can be made of acrylic sheet, with an opening to connect to the top of the mounting post. The left camera 613 is fastened to the top of the mounting plate, with its lens always facing the fixing area of ​​the left column of brush filaments 72 on the linear motion platform 2. The left light source mounting post 614 is located on the left side of the optical platform base plate 1, supporting the left light source mounting plate 615. The left light source 616 is fixed on the left light source mounting plate 615, with its emitting surface facing the left column of brush filaments 72, providing supplemental light for shooting. The right camera mounting post 621 is fixedly installed on the right side of the optical platform base plate 1, supporting the right camera mounting plate 622. The right camera 623 is fixed on the right camera mounting plate 622, with its lens facing the fixing area of ​​the right column of brush filaments 72 on the linear motion platform 2. The right light source fixing post 624 is located on the right side of the optical platform base plate 1, supporting the right light source fixing plate 625. The right light source 626 is fixed on the right light source fixing plate 625 to illuminate the right row of brush filaments 72.

[0048] During inspection, the linear motion platform 2 moves the brush filament assembly 7 to the designated position of the vision inspection module 6, and the left light source 616 and the right light source 626 are simultaneously turned on. The left camera 613 is specifically designed to capture images of the brush filament 72 on the left side of the linear motion platform 2, and the right camera 623 is specifically designed to capture images of the brush filament 72 on the right side. The two sets of cameras synchronously acquire images of the oblique side of each brush filament 72. Subsequently, the image processing system of the vision inspection module 6 calls preset algorithms, such as edge detection and angle calculation algorithms, to process the image of each brush filament 72, accurately calculate and output the bending angle data of each brush filament 72, compare it with the preset angle range, and determine whether it is qualified.

[0049] like Figure 8 As shown, the processed bristle assembly includes a bristle plate 71 and bristles 72. The ends of the bristles 72 are fixedly connected to the bristle plate 71. Before bending, the bristles 72 extend from the bristle plate 71 in a direction away from the plate body, with the extension direction perpendicular to the bristle plate 71. After bending, the bristles 72 form a vertical section and a bent section. The vertical section connects the bristle plate 71 and the bent section, and the bent section bends outward in a second direction. Specifically, the left row of bristles bends to the left in the second direction, and the right row of bristles bends to the right in the second direction.

[0050] Working principle During operation, the controller controls the linear slide 21 to move the loading platform 22 to the initial end of the wire cutting module 3, and places the wire brush assembly 7 on the loading platform 22. The position is determined by the side of the wire brush assembly 7 abutting against the positioning block 222, and the wire brush plate 71 is clamped with the frog pliers 223 to complete the fixation.

[0051] After the brush bristle assembly 7 is installed, the bristle cutting process is performed. The controller drives the loading platform 22 to move below the bristle cutting module 3, aligning the first set of brush bristles 72 with the bristle cutter 36. The horizontal movement module 33 of the bristle cutter drive module drives the bristle cutter 36 to move along the second direction, aligning it with the left column of brush bristles 72. The vertical movement module 34 drives the bristle cutter 36 to move along the third direction to the preset cutting position. The bristle cutter 36 closes to cut the left-side brush bristles. Then, the horizontal movement module 33 drives the bristle cutter 36 to switch to the right column to cut the right-side brush bristles. After one set is completed, the loading platform 22 moves along the first direction to the next set of brush bristles 72, repeating the operation until all brush bristles are cut.

[0052] The bending process is then performed. The loading platform 22 moves below the bending module 4, and the first set of brush filaments 72 aligns with the third and fourth connecting rods in their initial state. The two sets of electric push rods 224 extend, and the bending rods 226 move towards each other, abutting against the connection between the brush filaments 72 and the brush filament plate 71. The stepper motor 403 of the bending module starts, driving the slider 410 of the bending module to move. The third and fourth connecting rods symmetrically and synchronously tilt outwards to open to the preset bending angle, with a springback allowance reserved at the preset angle, cooperating with the bending rods 226 to complete the bending. Subsequently, the connecting rods reset, the electric push rods 224 retract, and the loading platform 22 moves to switch to the next set of brush filaments until all brush filaments are bent.

[0053] Perform the pressure testing procedure. The loading platform 22 moves to the bottom of the pressure testing module 5, and the servo motor 54 rotates to both sides in the second direction, so that the pressure sensor contact 57 is tangent to the bending section of the brush bristles on both sides, and the pressure data of each group of brush bristles is detected and recorded.

[0054] Visual inspection is performed. The loading platform 22 moves to the visual inspection module 6, multiple light sources are turned on, and cameras on both sides simultaneously capture images of the oblique side of the brush bristles 72 on the brush bristle assembly 7. The visual inspection module 6 calculates the bending angle of each brush bristle using an image processing algorithm to determine whether it is qualified. After the inspection is completed, the frog clamps 223 are manually released, the brush bristle assembly 7 is removed, and the entire processing and inspection process is completed.
