Therefore, it is necessary to use a detection device to detect the produced motor components;

[0003] The motor shaft is one of the main components of the motor. When detecting the motor shaft, usually the motor shaft is placed on the platform of the detection device, and a fixed rotation mechanism is used to fix and drive the motor shaft to rotate, so as to facilitate the detection mechanism to comprehensively detect the outer peripheral side of the motor shaft. However, during batch detection, it is necessary to frequently pick up and place single motor shafts onto the detection platform and fix or release the fixation, resulting in low detection efficiency. Therefore, this application proposes a component detection device. Utility Model Content

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0028] like Figures 1-6 As shown, a component detection device proposed in one embodiment of the present application includes:

[0029] The transmission mechanism 1 comprises a base 101, guide rods 102 are rotatably provided at both ends of the base 101, sprocket wheels 103 are fixedly provided at both ends of the guide rods 102, four sprocket wheels 103 correspond to each other in pairs, chains 104 are transmitted and wound around two corresponding sprocket wheels 103, a plurality of supporting rods 105 are connected in an array along the transmission direction of the two chains 104, preferably, a driving motor provided on the base 101 is connected to the end of one of the guide rods 102, the guide rod 102 is driven to rotate under the action of the driving motor, thereby driving the other guide rod 102 to rotate, thereby driving the sprocket wheel 103 to rotate, driving the chain 104 to transmit, when the motor shaft is detected, the motor shaft is placed on two adjacent supporting rods 105, and the two adjacent supporting rods 105 support and transmit the motor shaft;

[0030] The mounting bracket 2 is arranged on the base 101. An industrial camera 3 is arranged on the mounting bracket 2. The image projected by the industrial camera 3 (model: ANPVC2260) through the lens onto the sensor is transmitted to a machine device capable of storing, analyzing, and / or displaying. According to information such as pixel distribution, brightness, and color, it is converted into a digital signal. The image processing system performs various operations on these signals to extract the features of the target, such as area, quantity, position, and length, and then outputs the results according to the preset tolerance and other conditions, including size, angle, number, qualified / unqualified, presence / absence of defects, etc., to achieve the automatic recognition function. Preferably, a machine device supporting the industrial camera 3 is arranged on the base 101. When the motor shaft is transmitted to the lower part of the mounting bracket 2, the industrial camera 3 performs visual inspection on the motor shaft;

[0031] The clamping and rotating mechanism 4 is arranged on the base 101 and below the industrial camera 3. The clamping and rotating mechanism 4 includes two spline rods 401 that rotate through opposite sides of the inner wall of the base 101. Spline sleeves 402 are slidably sleeved on the opposite ends of the two spline rods 401. One end of one spline rod 401 is connected to a first motor 403 arranged on the base 101. A driving member 404 for driving the two spline sleeves 402 to slide synchronously and in opposite directions is arranged on the base 101. When the motor shaft is transmitted to the lower part of the mounting bracket 2 and is located between the two spline rods 401, at this time, the transmission of the motor shaft is stopped. The driving member 404 drives the two spline sleeves 402 to slide synchronously and in opposite directions. When the two spline sleeves 402 slide closer, the two spline sleeves 402 respectively abut against both ends of the motor shaft, thereby clamping and fixing the motor shaft. After the motor shaft is fixed, the first motor 403 does work, driving one of the spline rods 401 to rotate, thereby driving the motor shaft to rotate (since the supporting rod 105 is a rod and the motor shaft is also a rod, the motor shaft can meet the rotation requirement without detaching from the supporting rod 105), so that the industrial camera 3 can comprehensively inspect the circumferential side of the motor shaft. After the inspection of the motor shaft is completed, the driving member 404 drives the two spline sleeves 402 to slide away synchronously, and the fixation of the motor shaft can be released. At this time, the chain 104 continues to transmit, transporting the motor shaft that has been inspected, and then inspecting the subsequent transmitted motor shafts;

[0032] The feeding mechanism 5 is arranged at the input end of the transmission mechanism 1 and is used to sequentially convey components onto the transmission mechanism 1. By arranging the feeding mechanism 5, it sequentially conveys the motor shafts onto the supporting rods 105 and arranges the motor shafts in sequence, facilitating the sequential inspection of the motor shafts;

[0033] The motor shaft is transmitted by means of a sprocket 103, a chain 104 and a supporting rod 105, and then clamped and rotated by a clamping and rotating mechanism 4, so that during the detection of the motor shaft, not only can a comprehensive circumferential detection be carried out, but also it is not necessary to disengage from the supporting rod 105, reducing the time for picking and placing. After the detection is completed, the transmission continues, and the motor shafts are arranged in sequence for transmission and are detected in sequence, thereby improving the detection efficiency.

[0034] As Figure 4 shown, in some embodiments, the driving member 404 includes a second motor 4041 provided on the inner bottom wall of the base 101. A disc 4042 is fixedly provided on the output shaft of the second motor 4041. Two support rods 4043 are eccentrically hinged on the disc 4042. Connecting rods 4044 are slidably provided on the opposite inner walls of the base 101. Preferably, the connecting rod 4044 is configured as a U-shaped rod. One ends of the two connecting rods 4044 are respectively rotatably connected to the two spline cylinders 402, and the other ends of the two connecting rods 4044 are respectively hinged to the free ends of the two support rods 4043. When the second motor 4041 does work, its output drives the disc 4042 to rotate. Since the two support rods 4043 are eccentrically hinged to the disc 4042, when the disc 4042 rotates, the two support rods 4043 respectively pull or abut against the two connecting rods 4044 to drive the two spline cylinders 402 to slide synchronously and in opposite directions. Since the connecting rod 4044 is rotatably connected to the spline cylinder 402, the connecting rod 4044 can drive the spline cylinder 402 to slide along the spline rod 401, but does not affect the normal rotation of the spline cylinder 402.

[0035] As Figure 4 shown, in some embodiments, suction cups 6 are provided at the opposite ends of the two spline cylinders 402. By providing the suction cups 6, when the two spline cylinders 402 respectively abut against the two ends of the motor shaft, the suction cups 6 are in contact with the end faces of the motor shaft, and the adsorption of the suction cups 6 is used to increase the contact friction force between the spline cylinder 402 and the end face of the motor shaft, so that the fixing effect on the motor shaft is better. When the spline cylinder 402 moves away from the motor shaft under the stress of the connecting rod 4044, the adsorption of the suction cup 6 on the motor shaft is automatically released.

[0036] As Figure 2 shown, in some embodiments, a sleeve 7 is rotatably sleeved on the guide rod 102. Preferably, the sleeve 7 is made of a rubber sleeve. By rotatably providing the sleeve 7, during feeding, the collision between the motor shaft and the guide rod 102 is reduced. At the same time, when the motor shaft rotates, it rotates and abuts against the sleeve 7, reducing the rotational resistance and making the rotation of the motor shaft smoother.

[0037] As Figure 5 and Figure 6As shown, in some embodiments, the feeding mechanism 5 includes a feed bin 501 disposed on the base 101. The bottom of the feed bin 501 is communicated with a discharge channel 502. The opposite sides of the inner wall of the discharge channel 502 are rotatably penetrated by a rotating shaft 503. One end of the rotating shaft 503 is connected to a third motor 504 disposed on the feed bin 501. A cylinder 505 is fixedly provided on the rotating shaft 503. A groove 506 is formed on the outer surface of the cylinder 505. When detecting the motor shaft, a batch of motor shafts are neatly placed in the feed bin 501. Preferably, the groove 506 can only accommodate one motor shaft. When discharging materials, the third motor 504 operates, and its output shaft drives the rotating shaft 503 and the cylinder 505 to rotate. When the groove 506 is at the uppermost position, one of the motor shafts in the feed bin 501 drops into the groove 506. As the rotating shaft 503 and the cylinder 505 continue to rotate, and when the groove 506 is at the lowermost position, the motor shaft in the groove 506 drops between two adjacent supporting rods 105, thereby completing single sequential feeding. Moreover, there is a certain distance between two adjacent motor shafts, so that the motor shafts are sequentially fed and arranged for transmission.

[0038] As Figure 5 shown, in some embodiments, the number of grooves 506 is several and they are distributed in a circular array. One end of the rotating shaft 503 is connected to a driven sprocket 8. The output shaft of the third motor 504 is fixedly provided with a transmission dial 9 that is in transmission cooperation with the driven sprocket 8. Preferably, the number of grooves on both the groove 506 and the driven sprocket 8 is four. The transmission dial 9 includes a cut-off disc. A support plate is provided at the notch of the cut-off disc. A dial rod that is in sliding cooperation with the groove is provided on the support plate. The third motor 504 operates, and its output shaft drives the transmission dial 9 to rotate. When the transmission dial 9 rotates, the dial rod on it is in sliding cooperation with the groove. When the transmission dial 9 rotates one circle, the driven sprocket 8 rotates 90 degrees, thereby realizing the function of intermittent transmission. Therefore, when the rotating shaft 503 rotates 90 degrees, it will pause. During the pause time, the motor shafts in the feed bin 501 are more likely to fall into the groove 506, or the motor shafts in the groove 506 are more likely to fall onto the supporting rod 105.

[0039] As Figure 1 shown, in some embodiments, a removal mechanism 10 is provided on the base 101 and at the output end, which is used to remove unqualified components. By providing the removal mechanism 10, the qualified motor shafts continue to be transmitted, while the unqualified motor shafts are removed in sequence, thereby completing the sorting of qualified and unqualified components.

[0040] As Figure 3As shown, in some embodiments, the removal mechanism 10 includes an electric push rod 1001 disposed on one side of the base 101. The piston end of the electric push rod 1001 is connected to a push plate 1002. A discharge opening is formed through the side of the base 101 away from the electric push rod 1001. A material guide plate 1003 communicating with the discharge opening is provided on the base 101. Preferably, the removal mechanism 10 acts synchronously with the industrial camera 3. When the inspection of the unqualified motor shaft is completed, it continues to be transported. At this time, the industrial camera 3 inspects the next motor shaft. During the inspection process, the transport mechanism 1 is in a stopped state. At this time, the products that have been inspected and are unqualified just correspond to the discharge opening. The electric push rod 1001 does work, and its piston end drives the push plate 1002 to move horizontally, so as to push the unqualified motor shaft through the discharge opening onto the material guide plate 1003. A storage box can be provided below the material guide plate 1003, and the unqualified motor shaft rolls into the storage box through the material guide plate 1003.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
