Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of needle roller screening devices, and in particular to a needle roller quality screening device with detection function. Background Technology
[0002] In the field of machinery manufacturing, needle rollers are an important component of key parts such as bearings, and their quality directly affects the performance, stability, and service life of mechanical equipment. Defects such as dimensional inaccuracies, surface scratches, cracks, and missing pieces in needle rollers can cause abnormal wear and jamming during bearing operation, and even lead to equipment failure, resulting in production stoppages and economic losses.
[0003] Existing technology proposes an intelligent linkage control structure to realize a multi-dimensional composite detection structure, specifically including a multi-modal sensor fusion module: integrating a laser interferometer, a confocal microscope, and an eddy current sensor. A ring-shaped detection chamber is constructed, with 8-12 high-definition line-scan cameras evenly distributed along the circumference, combined with multiple sets of ring lights, backlights, and side lights to form a multi-angle illumination system. When the needle roller passes through the detection chamber, the line-scan cameras acquire images in high-speed scanning mode, and the images are generated into a complete surface image through an image stitching algorithm, ensuring no blind spots and improving the surface defect detection rate. A pneumatic ejection sorting mechanism is also provided, with a multi-stage pneumatic ejector design. Each sorting station is equipped with an independent high-speed solenoid valve and cylinder. When the detection system determines that the needle roller is unqualified, the central controller quickly triggers the solenoid valve at the corresponding station, and the cylinder rapidly extends to eject the needle roller to the defective product collection box. The entire sorting action has a response time of less than 50ms, achieving high-speed sorting.
[0004] Flexible sorting claws are manufactured using shape memory alloys or soft robotics technology, with their surfaces covered in silicone. These claws can adaptively deform according to the size and shape of the needle rollers. Existing screening devices lack flexibility in the conveying process, often employing fixed-gauge conveyor tracks that can only accommodate specific needle roller specifications. If the needle roller specifications change, the entire conveying system requires complex adjustments or even replacement, severely limiting production efficiency and equipment versatility. Therefore, this application proposes a needle roller quality screening device with a variable-gauge conveyor structure, capable of accurately detecting minute dimensional deviations while balancing detection efficiency and stability. Summary of the Invention
[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a needle roller quality screening device with detection function.
[0006] The technical solution of this utility model is as follows: A needle roller quality screening device with detection function includes a support frame and a conveying unit installed in the support frame. The end of the conveying unit is provided with a hopper. The conveying unit includes an inclined plate that is inclined. A conveying track for the needle roller to move is opened on the inclined plate. A spacing adjustment unit is installed in the conveying track. The spacing adjustment unit includes a rotating rod installed below the inclined plate. A track plate connected to the rotating rod is provided in the conveying track.
[0007] Optionally, buffer grooves are provided on both sides of the support frame, and support rods are fixedly connected to both sides of the inclined plate, with the ends of the support rods slidingly disposed within the buffer grooves.
[0008] The top of the support rod is connected to a buffer spring that is connected to the inner wall of the top of the buffer groove.
[0009] Optionally, the spacing adjustment unit further includes a miniature drive motor installed on the lower surface of the inclined plate, the output end of which is fixedly connected to one end of the rotating rod.
[0010] Optionally, the other end of the rotating rod is connected to a fixing block that is fixedly connected to the lower surface of the inclined plate.
[0011] Optionally, the rotating rod is provided with a bidirectional thread at the position corresponding to each set of conveying tracks, and a connecting block sleeved on the outer ring of the bidirectional thread is fixedly connected to the bottom of the track plate.
[0012] The track slab is an arc-shaped slab.
[0013] Optionally, an adjustment port is provided at the corresponding position of the conveying track, and two connecting blocks in the same group pass through one adjustment port.
[0014] Optionally, each of the conveying tracks has multiple material discharge ports that penetrate the inclined plate along its length.
[0015] Optionally, an intelligent detection component is also provided above the conveying unit. The intelligent detection component includes a vision detection module for identifying needle rollers and a sorting actuator for picking up defective needle rollers.
[0016] A sorting roller is rotatably installed inside the hopper, and a sorting motor is installed on the side wall of the hopper at one end of the sorting roller.
[0017] A collection frame is provided below the conveying unit.
[0018] Compared with the prior art, the present invention has the following beneficial technical effects:
[0019] This utility model provides a stable and orderly transmission channel for the needle rollers through the inclined plate and the conveying track in the conveying unit. With the bidirectional thread design of the rotating rod in the spacing adjustment unit and the connecting block connected to it, the spacing of the needle rollers can be precisely adjusted to adapt to the needle roller conveying and screening of different specifications.
[0020] In this utility model's intelligent detection component, the vision detection module can perform comprehensive detection of the roller needles, accurately identify problems such as dimensional deviations and surface defects, while the sorting actuator can quickly grab defective roller needles to achieve accurate sorting. By installing a vibrator component at the bottom of the inclined plate, the roller needles are exposed on multiple sides, ensuring the quality of the roller needles in all aspects, reducing the occurrence of missed detections, and thus improving the detection accuracy of the roller needles.
[0021] In summary, this utility model can precisely adjust the needle roller spacing, adapt to different specifications of needle roller conveying and screening, improve equipment adaptability, and the vibrator assembly exposes the needle rollers on multiple sides, reducing missed detections and improving detection accuracy.

[0040] Example
[0041] like Figure 1-2 As shown, the present invention proposes a needle roller quality screening device with detection function, including a support frame 1 and a conveying unit 5 installed in the support frame 1. A hopper 2 is provided at the end of the conveying unit 5, and an intelligent detection component is also provided above the conveying unit 5. The intelligent detection component includes a visual detection module 3 for identifying needle rollers and a sorting actuator 4 for grasping defective needle rollers. A sorting roller 22 is rotatably installed in the hopper 2, and a sorting motor 21 is provided at one end of the sorting roller 22 and installed on the side wall of the hopper 2. A collection frame 7 is provided below the conveying unit 5.
[0042] like Figure 1-5As shown, the conveying unit 5 includes an inclined plate 51 with an inclination. Buffer grooves 10 are provided on both sides of the support frame 1. Support rods 55 are fixedly connected to both sides of the inclined plate 51. The ends of the support rods 55 are slidably disposed in the buffer grooves 10. A buffer spring 56 connected to the top inner wall of the buffer groove 10 is connected to the top of the support rods 55.
[0043] Combination Figure 3 , Figure 4 and Figure 5 As shown, the inclined plate 51 has a conveying track 52 for the movement of needle rollers. Each conveying track 52 has multiple material discharge ports 53 penetrating the inclined plate 51 along its length. An adjustment port 54 is provided at a corresponding position on each conveying track 52. Two connecting blocks 63 of the same group pass through one adjustment port 54. A spacing adjustment unit 6 is installed inside the conveying track 52. The spacing adjustment unit 6 allows the two track plates 64 in each conveying track 52 to move relative to or away from each other, thereby adjusting the inner diameter of the conveying track to accommodate small-diameter needle rollers. The spacing adjustment unit 6 includes a component installed below the inclined plate 51. The rotating rod 62 has a fixed block at one end that is fixedly connected to the lower surface of the inclined plate 51. The rotating rod 62 has a bidirectional thread at the position corresponding to each set of conveying rails 52. The spacing adjustment unit 6 also includes a micro drive motor 61 installed on the lower surface of the inclined plate 51. The output end of the micro drive motor 61 is fixedly connected to one end of the rotating rod 62. The conveying rail 52 is provided with a rail plate 64 connected to the rotating rod 62. The bottom of the rail plate 64 is fixedly connected to a connecting block 63 that is sleeved on the outer ring of the bidirectional thread. Two connecting blocks 63 in the same set pass through an adjustment port 54. The rail plate 64 is an arc-shaped plate.
[0044] In this embodiment, the needle rollers are arranged and conveyed by the hopper 2. Relying on their own gravity and the electromagnetic vibrator installed below them, high-frequency vibration is generated by electromagnetic force. The vibration frequency and amplitude can be precisely controlled, causing the needle rollers to roll down along the conveying track 52 channel to complete the initial conveying. The support rods 55 on both sides of the inclined plate 51 slide in the buffer groove 10 on the side wall of the support frame 1 to achieve vibration, thereby facilitating the unloading of the needle rollers.
[0045] When performing roller screening operations of different specifications, the inner diameter of the conveying track 52 is adjusted to adjust the track radius. Specifically, the micro drive motor 61 drives the rotating rod 62 to rotate. The bidirectional thread of the rotating rod 62 at the position of each set of conveying tracks 52 drives the connecting block 63 to move, so that the two track plates 64 in one conveying track 52 can move towards or away from each other, thereby precisely adjusting the spacing between the rollers in the conveying track 52.
[0046] During the needle roller conveying process, when the needle roller moves to the underside of the intelligent detection component, the vision detection module 3 performs an all-round inspection of the needle roller. Through image recognition, size measurement and other technologies, it accurately determines whether the needle roller has defects such as size deviation, surface scratches, cracks and so on. If a defective needle roller is detected, the sorting actuator 4 is immediately started. Using mechanical gripping or pneumatic adsorption, the defective needle roller is grabbed from the conveying channel and sorted into the collection box. The collection box 7 set in the embodiment is used to collect the needle rollers that are screened and fall from the discharge port 53.
[0047] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
