Description

Technical Field

[0001] This invention belongs to the field of motor component testing technology, and relates to a fully automatic visual inspection device for brush holders. Background Technology

[0002] As a critical conductive component of a motor, the dimensional accuracy, appearance defects, and assembly quality of the brush holder directly determine the motor's operational reliability. Traditional inspection methods rely on manual visual inspection and measuring tools, which are inefficient, prone to large errors, and have a high rate of missed inspections, making them unsuitable for large-scale production. Existing semi-automatic brush holder inspection equipment can only perform single-parameter inspections, has low levels of automation and integration, and lacks standardized inspection standards. Current similar equipment generally suffers from inaccurate workpiece positioning, poor algorithm adaptability, and poor multi-station coordination, failing to meet the requirements for high-precision and high-stability inspection.

[0003] Chinese patent CN210982679U discloses a testing fixture for the electrical performance of an automotive sunroof motor brush holder. The fixture includes a testing cabinet containing a testing center and a base plate. The testing cabinet includes a testing platform and a back panel. The front edge of the testing platform has a raised strip with a detachable slider that can slide left and right. A master switch is mounted on the slider and connected to the testing center. A viewing window is installed in the middle of the upper part of the front surface of the back panel, and a signal input connector is installed at the lower left corner of the front surface. Bases are detachably mounted at the center of both ends of the top surface of the base plate. A support block is installed at the front left end of the top surface of the base plate. The support block is integrally formed from a bottom horizontal block, a vertical block, and a top horizontal block. A first testing rod is mounted on the top horizontal block and connected to a first testing input line. Two springs are installed between the two bases on the top surface of the base plate. Guide rods are sleeved inside the springs, and the bottom of the guide rods is fixedly connected to the top surface of the base plate.

[0004] The patent provides a fixed manual tooling for testing the electrical performance of a car sunroof motor brush holder. It lacks an automatic loading and unloading structure and an automatic workpiece transfer structure. The workpiece clamping, alignment, disassembly, and placement are all done manually, resulting in low work efficiency and making it unsuitable for mass industrial production lines.

The spraying lifting module is fixedly installed on the upper part of the support platform. An installation plate is connected to the spraying lifting module. The spraying execution head is fixedly connected to the installation plate.

[0010] In the aforementioned fully automatic brush holder visual inspection equipment, a second tooling fixture is fixedly installed on the upper end of the support platform, and the second tooling fixture is located near the qualified product discharge mechanism.

[0011] In the aforementioned fully automatic brush holder visual inspection equipment, a qualified product dispensing and gripping mechanism is fixedly installed on the worktable surface on one side of the support platform and the qualified product dispensing mechanism.

[0012] In the aforementioned fully automatic brush holder visual inspection equipment, a plurality of through holes are provided on the worktable, and a first L-shaped connecting plate is fixedly installed on one side of the worktable. A first longitudinal ring light source is installed at the lower end of the first L-shaped connecting plate, and a first filter component is installed at the upper end of the first L-shaped connecting plate.

[0013] In the aforementioned fully automatic brush holder visual inspection equipment, a second L-shaped connecting plate is fixedly installed on the worktable surface at the outer periphery of the rotating material loading mechanism.

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0020] like Figures 1 to 4 As shown, this embodiment includes a frame assembly 1 and a testing equipment assembly integrated thereon. The upper end of the frame assembly 1 has a flat worktable 110 integrally formed, which provides a stable installation reference for each functional mechanism. The testing equipment assembly integrates a rotating material loading mechanism 2, a feeding mechanism 3, a vision inspection mechanism 4, a QR code spraying mechanism 8, a qualified product discharge mechanism 5, a non-qualified product discharge mechanism 6, and a sorting robot mechanism 7 in sequence according to the operation process, so as to realize the fully automated testing and circulation of the brush holder.

[0021] like Figures 1 to 4As shown, the rotating material loading mechanism 2 is the core indexing unit for the entire machine's workpiece flow, including a cam divider 21, a material loading turntable 22, an indexing drive motor 23, an output flange 25, a support turntable 26, and a support bracket 27. The indexing drive motor 23 is fixedly installed on the side of the cam divider 21, and the output shaft of the indexing drive motor 23 is driven by the internal transmission structure of the cam divider 21, providing high-precision intermittent indexing power for the material loading turntable. The upper output end of the cam divider 21 is coaxially fixedly connected to the output flange 25. The upper end of 25 is coaxially connected and fixed with a support turntable 26. The rigid connection structure of the flange effectively eliminates transmission gap and assembly eccentricity error, ensuring the overall transmission coaxiality. The material-carrying turntable 22 is coaxially sleeved and fixed to the upper end of the cam divider 21. Several first tooling fixtures 24 are evenly arranged on the outer circumferential surface of the material-carrying turntable 22 and locked with bolts. The first tooling fixture 24 has a limiting positioning groove that matches the shape of the brush holder, which can accurately limit and fix the brush holder to be tested, ensuring the consistency of the workpiece's posture throughout the entire process of the turntable's rotation.

[0022] like Figures 1 to 4 As shown, the loading mechanism 3 corresponds to the initial loading station layout of the rotating loading mechanism 2, including a loading conveyor line 31 and a loading transfer mechanism 32. The loading conveyor line 31 is fixedly installed on the upper end of the worktable 110 on one side of the rotating loading mechanism 2 by anchor bolts. Several loading positioning fixtures 311 are fixedly arranged at intervals on the conveyor belt of the loading conveyor line 31. The loading positioning fixtures 311 are used to carry the original workpiece to be inspected and provide a unified and standardized initial positioning reference for the transfer and gripping process. The loading transfer mechanism 32 is fixedly installed on the upper end of the worktable 110 on the side of the discharge end of the loading conveyor line 31. It is used to automatically grip and smoothly transfer the workpiece to be inspected in the loading positioning fixture 311 to the first tooling fixture 24 of the loading turntable 22.

[0023] To elaborate further, such as Figure 4As shown, the loading and transfer mechanism 32 is a two-axis pneumatic transfer structure, including a mounting base 321, support columns 322, a transverse transfer drive module 323, a longitudinal lifting drive module 324, and pneumatic clamping jaws 325. The mounting base 321 is fixed to the upper end of the worktable 110 by locking bolts, and the two support columns 322 are vertically fixed to the upper end face of the mounting base 321. The transverse transfer drive module 323 is horizontally fixed at the top of the support columns 322 to achieve the overall horizontal direction of the mechanism. The vertical lifting drive module 324 is slidably connected to the sliding end of the horizontal transfer drive module 323, enabling vertical lifting motion. The pneumatic clamping jaw 325 is locked and fixed to the bottom execution end of the vertical lifting drive module 324, and achieves stable clamping and unloading of the workpiece through pneumatic opening and closing. At the same time, the end of the horizontal transfer drive module 323 is equipped with a stroke limit component to accurately limit the transfer stroke, calibrate the two key stopping points of picking up and unloading, and ensure the workpiece transfer positioning accuracy.

[0024] like Figures 1 to 2 As shown, the visual inspection mechanism 4 is arranged around the inspection station of the material carrier turntable 22, including a visual acquisition component 41 and a visual light source component 42. The visual acquisition component 41 is equipped with an industrial camera and an optical lens. A mounting bracket 43 is welded and fixed on the worktable surface 110 on one side of the outer circumference of the material carrier turntable 22. The visual acquisition component 41 is fixed to the mounting bracket 43 near the top by locking components. The visual light source component 42 is installed on the mounting bracket 43 directly below the visual acquisition component 41, forming a coaxial imaging layout to ensure the clarity of image acquisition.

[0025] To elaborate further, such as Figures 1 to 2 As shown, a plurality of through holes 120 are provided on the worktable 110. A first L-shaped connecting plate 10 is fixedly installed on the worktable 110 on the side of the through holes 120 by means of corner brackets. A first ring light source 11 arranged longitudinally is installed at the lower end of the first L-shaped connecting plate 10, and a first filter component 12 is installed at the upper end of the connecting plate. A second L-shaped connecting plate 13 is fixedly installed on the worktable 110 on the outer rear side of the rotating material loading mechanism 2. A second ring light source 14 oriented horizontally is installed at the rear end of the second L-shaped connecting plate 13, and a second filter component 15 is installed at the front end of the connecting plate. In this embodiment, a longitudinal and horizontal dual-angle light source layout structure is adopted. The two sets of ring light sources are adapted to the lighting requirements of different shapes of the brush holder. The matching filter components can effectively filter the mirror reflection of the metal workpiece surface and the ambient light glare, eliminate the problem of overexposure in imaging, and greatly improve the imaging clarity of the workpiece appearance defects and size contours, avoiding the problems of false detection and missed detection in visual inspection.

[0026] To elaborate further, such as Figures 1 to 3As shown, the upper end of the cam divider 21 is fixedly connected to the output flange 25 by bolts. The upper end of the output flange 25 is coaxially connected to the support turntable 26. The upper end of the support turntable 26 is welded and fixed to the support bracket 27, which is used to install the spring pressure detection mechanism.

[0027] To elaborate further, such as Figures 1 to 2 As shown, the qualified product unloading mechanism 5 and the unqualified product unloading mechanism 6 are respectively arranged on the left and right sides of the sorting robot mechanism 7. With the central vertical axis of the sorting robot mechanism 7 as the symmetry reference, the whole structure forms a left-right mirror symmetry structure. The sorting robot mechanism 7 can accurately clamp and divert the inspected workpieces according to the judgment result of the detection system. Qualified workpieces are transported to the qualified product unloading mechanism 5, and unqualified workpieces are transported to the unqualified product unloading mechanism 6, so as to achieve complete isolation and diversion of good and bad products and eliminate the risk of workpiece mixing in batch production.

[0028] To elaborate further, such as Figure 1 and Figure 4 As shown, a QR code spraying mechanism 8 is fixedly installed on the workbench 110 corresponding to the qualified product transfer station. The QR code spraying mechanism 8 includes a support platform 81, a spraying execution head 82, a spraying lifting module 83, a mounting plate 84, and a second tooling fixture 85. The support platform 81 is fixed to the upper end of the workbench 110 on one side of the qualified product discharge mechanism 5 by anchor bolts. The spraying lifting module 83 is vertically locked and fixed to the upper end of the support platform 81. The sliding end of the spraying lifting module 83 is fixedly connected to the mounting plate 84. The spraying execution head 82 is rigidly fixedly connected to the mounting plate 84. The spraying lifting module can drive the spraying execution head to complete the vertical height adjustment. The second tooling fixture 85 is fixedly installed at the upper end of the support platform 81 near the qualified product discharge mechanism 5. The fixture has a dedicated positioning reference inside, which is used for precise positioning during workpiece spraying operations, ensuring accurate and unified QR code spraying position and realizing the unique identification code spraying binding of qualified workpieces.

[0029] To elaborate further, such as Figures 1 to 2 As shown, a qualified product dispensing gripping mechanism 9 is fixedly installed on the worktable 110 between the support platform 81 and the qualified product dispensing mechanism 5. The qualified product dispensing gripping mechanism is a linear slide transfer structure, which can smoothly clamp and transfer the qualified electric brush frame that has completed the QR code spraying operation to the conveyor line of the qualified product dispensing mechanism 5, smoothly connect the spraying station and the final dispensing station, match the overall machine operation rhythm, and ensure that the entire process is automated and uninterrupted.

[0030] The working principle of this invention is as follows: The feeding conveyor line 31 transports the brush holder to be inspected to the feeding station. The feeding transfer mechanism 32 then grabs the workpiece and transfers it to the first tooling fixture 24 of the loading turntable 22 to complete automated feeding. The indexing drive motor 23 drives the cam divider 21 to run, driving the loading turntable 22 to rotate intermittently with high precision, and sequentially transporting the workpiece to each inspection station. When the workpiece arrives at the visual inspection station, the dual ring light sources and matching filter components simultaneously illuminate and extinct the light, and the visual acquisition component completes the inspection of the workpiece's appearance and dimensional defects. Subsequently, the workpiece flows to the spring pressure inspection station, where the spring pressure inspection mechanism presses down to complete the mechanical performance inspection of the internal springs of the brush holder. The control system summarizes all inspection data and completes the workpiece's qualification level determination. The subsequent sorting robot arm 7 performs a diversion action based on the system's judgment result: unqualified workpieces are directly transferred to the unqualified product discharge mechanism 6 for discharge; qualified workpieces are transferred to the QR code spraying mechanism 8 to complete the traceability QR code spraying, and then the qualified product discharge gripping mechanism 9 smoothly transfers the workpiece to the qualified product discharge mechanism 5 to complete the finished product discharge.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.

[0032] Although this document uses a variety of terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of the invention; interpreting them as any additional limitation would contradict the spirit of the invention.
