Description

Technical Field

[0001] The utility model relates to the field of quality inspection devices, in particular to a quality inspection system for a motor shaft. Background Art

[0002] The motor shaft is a cylindrical component that extends from the motor and its housing. It serves as the primary support and connector for the armature in the motor and the output of the motor's power. Its purpose is to convert the motor's energy into its final form. Precision pins and the motor shaft provide the motor's speed and torque, making them essential components. After machining, the motor shaft must be inspected for overall dimensions and surface finish. The motor shaft's ends are designed to connect to the motor's main body, such as tapping, so internal defects must also be inspected. Therefore, after machining, the motor shaft requires multi-angle inspection. Existing motor shafts are primarily inspected in large quantities on assembly lines. However, due to imperfect spatial distribution and inspection angles of the inspection equipment, large-scale inspections suffer from limited inspection angles and a narrow inspection range, making it impossible to quickly identify surface defects. Furthermore, if defects are not detected on the motor shaft, they cannot be removed promptly, leading to quality issues during motor assembly and operation. Utility Model Content

[0051] like Figure 1-3 , a motor shaft quality inspection system, comprising: a detection and transmission mechanism 1, a feeding mechanism 2 and a detection mechanism 3;

[0052] The detection and conveying mechanism 1 is provided with a transparent rotating disc 11, which rotates around the center of the circle, driving the feeding troughs 111 distributed along the circumference of the transparent rotating disc 11 to rotate;

[0053] The output end of the feeding mechanism 2 is connected to the feeding trough 111, and is used to output the horizontally placed motor shaft to the feeding trough 111;

[0054] The detection mechanism 3 includes: a vertical size detection component 31, an end tilt detection device 32, a vertical multi-angle detection component 33 and a horizontal side detection device 34;

[0055] The detection ends of the vertical size detection component 31, the end tilt detection device 32, the vertical multi-angle detection component 33 and the horizontal side detection device 34 are distributed within the rotation range of the transparent rotating disk 11;

[0056] The vertical size detection assembly 31 includes: a vertical size detection device 311 and a vertical baffle 312; the detection end of the vertical size detection device 311 is located directly above the feeding trough 111, and is used to detect the size of the motor shaft in the feeding trough 111; the vertical baffle 312 is provided below the feeding trough 111;

[0057] The detection end of the end tilt detection device 32 is tilted downward toward the feeding trough 111, and is used to detect the structure of the motor shaft at the end in the feeding trough 111;

[0058] The vertical multi-angle detection component 33 includes: a vertical detection industrial camera 331 and a prism module 332;

[0059] The detection end of the vertical detection industrial camera 331 is downwardly directed toward the feeding trough 111; the prism module 332 is located below the transparent rotating disk 11; the prism module 332 is provided with a plurality of reflective prisms 3321 around the motor shaft of the feeding trough 111;

[0060] The detection end of the horizontal side detection device 34 is horizontally oriented toward the motor shaft of the feeding trough 111 , and is used to detect the surface structure of the motor shaft in the feeding trough 111 .

[0061] The present solution provides a quality inspection system for a motor shaft, which transmits a horizontally placed motor shaft through a transparent rotating disc 11, driving the motor shaft to pass through a vertical dimension detection device 311, an end tilt detection device 32, a vertical multi-angle detection component 33 and a horizontal side detection device 34 in sequence. Based on the angular distribution of the detection ends of the vertical dimension detection device 311, the end tilt detection device 32, the vertical multi-angle detection component 33 and the horizontal side detection device 34, the present solution can realize multi-angle detection of the motor shaft, solving the problem that the existing motor shaft cannot identify surface defects in a short time during large-scale inspection.

[0062] Specifically, the transparent rotating disc 11 is used to receive the motor shaft continuously output by the feeding mechanism 2. The motor shaft remains horizontally flat, and the slot wall of the feeding trough 111 can limit the position of the motor shaft, which can prevent the transparent rotating disc 11 from shifting during rotation, thereby improving the detection stability. In this way, the transparent rotating disc 11 drives each motor shaft to be transmitted to the detection mechanism 3 under the action of rotation; the detection mechanism 3 includes: a vertical size detection device 311, an end tilt detection device 32, a vertical multi-angle detection component 33 and a horizontal side detection device 34. The arrangement order of the four on the transparent rotating disc 11 can be distributed according to actual conditions; Figure 1In one embodiment, the vertical size detection device 311, the end tilt detection device 32, the vertical multi-angle detection component 33 and the horizontal side detection device 34 are distributed in sequence on the outer circumference of the transparent rotating disk 11; for the vertical size detection device 311, its detection end is vertically facing the motor shaft of the feed trough 111. Since the motor shaft is horizontally placed, when the detection end of the vertical size detection device 311 is downwardly facing the motor shaft, the outer contour features of the motor shaft can be directly obtained. The vertical baffle 312 is arranged below the feed trough 111 to block the light below, so that the outer contour features of the motor shaft are displayed on the upper surface of the vertical baffle 312, thereby highlighting the identification features of the motor shaft, and then the length, diameter and dimensions of different steps of the motor shaft can be obtained; if the acquired parameters of the motor shaft are significantly different from the preset standard parameters, the detected motor shaft is recorded as unqualified. For the end tilt detection device 32, its detection end is tilted downward toward the motor shaft of the feed trough 111; the motor shaft generally has an end hole milled on the end, and a tooth structure may also be further processed in the end hole. Therefore, when the detection end of the end tilt detection device 32 is tilted from top to bottom to illuminate the end hole, the contour features of the end hole can be obtained, thereby identifying whether the end features of the motor shaft are standard. For the vertical multi-angle detection component 33, this solution uses a vertical detection industrial camera 331 in conjunction with a prism module 332 to detect the motor shaft. The detection end of the vertical detection industrial camera 331 is downward toward the motor shaft of the feed trough 111, and the prism module 332 is located below the transparent rotating disk 11. The prism module 332 is provided with multiple reflective prisms 3321 around the outer circumference of the motor shaft. In addition to obtaining vertical downward images, the vertical detection industrial camera 331 can also obtain multiple images of the outer side of the motor shaft reflected by the reflective prism 3321 below the motor shaft, thereby obtaining multi-angle images of the motor shaft; in this regard, the vertical detection industrial camera 331 can directly or indirectly compare the obtained image with the preset standard image to identify whether there is a defect, and record it if so. The horizontal side detection device 34 has its detection end oriented horizontally, specifically toward the motor shaft. This allows for horizontal acquisition of images of the motor shaft's surface structure, thereby supplementing the motor shaft inspection. This primarily addresses the blind spots encountered by the vertical multi-angle detection assembly 33 when inspecting from top to bottom. Furthermore, it can further supplement the inspection of the tapping structure for defects, which, in the most optimal embodiment, can serve as the final inspection step. This solution enables multi-angle inspection of the motor shaft, resolving the issue of existing large-scale inspections of motor shafts, which prevent the rapid identification of surface defects.

[0063] The detection device in the detection mechanism 3 of this scheme is a well-known device capable of identifying surface defects, such as an industrial camera and a light source cooperating with the industrial camera, which can obtain visual images of different positions of the motor shaft and identify image differences based on well-known means such as algorithms and image processing, for example, by comparing with a preset standard image to determine whether there are defects.

[0064] Optimally, the detection end of the horizontal side detection device 34 and the circumferential diameter direction of the transparent rotating disk 11 are located in the same plane.

[0065] When the detection end of the horizontal side detection device 34 and the circumferential diameter direction of the transparent rotating disk 11 are located in the same plane, that is, when the detection end of the horizontal side detection device 34 is facing the center of the transparent rotating disk 11, it is equivalent to the detection end of the horizontal side detection device 34 being directly opposite the center of the transparent rotating disk 11; and the feeding trough 111 of this scheme is distributed along the circumference of the transparent rotating disk 11, so the feeding trough 111 can drive the motor shaft to pass through the detection end of the horizontal side detection device 34 at an angle close to 90 degrees, and the horizontal side detection device 34 can obtain the entire side of the motor shaft; especially when the motor shaft rotates to maintain 90 degrees with the detection end of the horizontal side detection device 34, in addition to obtaining images at 90 degrees, the images at greater than 90 degrees and less than 90 degrees are symmetrically distributed, so this scheme can also obtain more images between angles of 90±5 degrees, and then according to the decolorization and graying treatment, the angle difference can better highlight surface defects, thereby maximizing the supplementation of the blind area of ​​the vertical multi-angle detection component 33 and improving the detection accuracy.

[0066] Optimally, the motor shaft is provided with an end hole at the front end in the conveying direction; the detection end of the end tilt detection device 32 is tilted downward toward and tangent to the feeding trough 111.

[0067] The feed trough 111 of the present solution is distributed along the circumference of the transparent rotating disc 11. Therefore, when the detection end of the end tilt detection device 32 is tilted downward toward and tangent to the feed trough 111, the detection end of the end tilt detection device 32 can be aligned straight downward with the end hole of the motor shaft at the front end of the transmission, so that the end hole can expose a larger range of the inner wall at this angle, so that the color difference between the inside and outside of the end hole of the obtained image after decolorization and graying processing is most obvious, and the tapping structure of the end hole is clearest, thereby facilitating the identification of defects.

[0068] Optimally, the feeding mechanism 2 further includes: a feeding channel 21 and a feeding limit block 22;

[0070] The feed channel 21 is connected to the feed trough 111 and is used to continuously output the motor shaft to the feed trough 111; the feed trough 111 is provided with a pair of feed limit blocks 22, and a feed guide port 221 is formed between the two feed limit blocks 22, which can be used to limit the path of the motor shaft from the feed channel 21 to the feed trough 111, so that the motor shaft is output to the feed trough 111 according to a preset path; the feed limit block 22 is provided with an inclined surface 222, and the inclined surface 222 is provided at the feed guide port 221, so that the motor shaft in the feed guide port 221 can be output to the feed trough 111 along the inclined surface 222; and the input end of the feed channel 21 can be connected to the vibration disk 23, and the vibration disk 23 can continuously input the horizontally placed motor shaft into the feed channel 21.

[0071] Optimally, the feeding mechanism 2 further includes: a vibration plate 23;

[0072] The vibration disk 23 is used to store the motor shaft. The output end of the vibration disk 23 is connected to the input end of the feeding channel 21 for outputting the motor shaft to the feeding channel 21 .

[0073] This solution preferably uses a vibration plate 23 to provide feeding for the feeding channel 21. The vibration plate 23 can arrange the motor shafts in an orderly manner and output them to the feeding channel 21, thereby realizing the fully automatic output of the motor shafts to the feeding trough 111.

[0074] Optimally, the detection mechanism 3 further includes: a main control device and an in-place detection component 36;

[0075] The main control device is communicatively connected to the detection and conveying mechanism 1, the feeding mechanism 2 and the detection mechanism 3;

[0076] The in-place detection component 36, the vertical size detection device 311, the end tilt detection device 32, the vertical multi-angle detection component 33 and the horizontal side detection device 34 are sequentially distributed within the rotation range of the transparent rotating disc 11;

[0077] The in-position detection assembly 36 includes: an in-position horizontal frame 361, an in-position vertical frame 362, a laser in-position emitting device 363 and a laser in-position sensing device 364;

[0078] The in-position horizontal frame 361 is arranged above the transparent rotating disc 11; the in-position vertical frames 362 are connected to the in-position horizontal frame 361 in pairs, one of the in-position vertical frames 362 is installed with the laser in-position emitting device 363, and the other in-position vertical frame 362 is installed with the laser in-position sensing device 364; the emitting end of the laser in-position emitting device 363 is linearly aligned with the sensing end of the laser in-position sensing device 364, and the motor shaft of the feeding trough 111 passes between the emitting end of the laser in-position emitting device 363 and the sensing end of the laser in-position sensing device 364, and the laser in-position sensing device 364 is communicatively connected to the main control device.

[0079] The in-place detection component 36 is arranged at the first station of the detection mechanism 3, and is mainly used to identify each motor shaft passing through, so as to feed back to the main control device, so that the main control device can call the detection transmission mechanism 1, the feeding mechanism 2 and the detection mechanism 3 according to the in-place signal; specifically, the in-place vertical frames 362 are arranged in pairs on the in-place horizontal frames 361, one in-place vertical frame 362 is installed with a laser in-place emitting device 363, and the other in-place vertical frame 362 is installed with a laser in-place sensing device 364. The in-place horizontal frame 361 can make the laser in-place emitting device 363 and the laser in-place sensing device 364 suspended above the transparent rotating disc 11, so as not to affect the normal rotation and material transmission of the transparent rotating disc 11, so that the motor shaft of the feeding trough 111 passes horizontally between the emitting end of the laser in-place emitting device 363 and the sensing end of the laser in-place sensing device 364; under normal conditions, the laser The emitting end of the light-in-place emitting device 363 emits a laser to the sensing end of the laser-in-place sensing device 364. When the motor shaft of the feed trough 111 rotates to pass between the emitting end of the laser-in-place emitting device 363 and the sensing end of the laser-in-place sensing device 364, the motor shaft of the feed trough 111 will block the laser, so that the sensing end of the laser-in-place sensing device 364 cannot receive the laser, indicating that the motor shaft has passed. The laser-in-place sensing device 364 feeds back to the main control device, and the main control device then mobilizes the detection and transmission mechanism 1, the feeding mechanism 2 and the detection mechanism 3 to start, for example, controlling the transparent rotating disc 11 to rotate one unit, the feeding mechanism 2 outputs a motor shaft to the feed trough 111, and the vertical size detection device 311, the end tilt detection device 32, the vertical multi-angle detection component 33 and the horizontal side detection device 34 are initialized.

[0080] Optimally, the detection mechanism 3 further includes: a position adjustment component 35;

[0081] The position adjustment assembly 35 includes: an adjustment frame 351, a detection horizontal track 352, a detection horizontal slider 353, a detection vertical track 354 and a detection slider 355;

[0085] Optimally, it further comprises: a rejecting device 5;

[0086] The feeding mechanism 2, the detecting mechanism 3 and the rejecting device 5 are sequentially distributed along the rotation direction of the transparent rotating disc 11;

[0087] The rejecting device 5 includes: a discharge receiving container 51 and a classification driving mechanism 52;

[0088] Multiple discharge receiving containers 51 are distributed along the outer circumference of the transparent rotating disc 11, and each discharge receiving container 51 corresponds to a classification drive mechanism 52; the classification drive mechanism 52 is communicatively connected to the detection mechanism 3; the output end of the classification drive mechanism 52 is toward the feeding trough 111, and is used to drive the motor shaft of the feeding trough 111 to move, so that the motor shaft is output to the input end of the discharge receiving container 51.

[0089] When the feed trough 111 rotates the motor shaft to the input end passing through the discharge receiving container 51, the classification drive mechanism 52 can be activated. The output end of the classification drive mechanism 52 can drive the motor shaft of the feed trough 111 to move, so that the motor shaft of the feed trough 111 is output to the input end of the discharge receiving container 51, thereby automatically outputting the motor shaft to the discharge receiving container 51, achieving the effect of automatically discharging the motor shaft. The classification drive mechanism 52 is communicatively connected to the detection mechanism 3. Based on the detection results of the detection mechanism 3, the classification drive mechanism 52 outputs the motor shaft to a certain discharge receiving container 51 when each motor shaft moves to the discharge receiving container 51, thereby achieving automatic classification of the motor shafts.

[0090] In one embodiment, the classification drive mechanism 52 may be a mechanism for driving linear movement, such as a well-known linear drive device such as an air cylinder, an oil cylinder, or a manipulator.

[0091] Optimally, the classification drive mechanism 52 is an air blowing device, and the classification drive mechanism 52 is used to blow air toward the motor shaft of the feeding trough 111 to move the motor shaft to the input end of the discharge receiving container 51 .

[0092] The classification drive mechanism 52 is an air blowing device, which can drive the motor shaft to move without moving the output end back and forth.

The airflow pushes the motor shaft to the input end of the discharge receiving container 51, and the motor shaft can roll to the discharge receiving container 51.

[0093] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
