Abstract
Description
Technical Field
[0001] The utility model relates to the field of stud processing equipment, in particular to a visual recognition mechanism for loading stud fasteners. Background Art
[0002] The thread manufacturing process for stud fasteners requires consistent orientation during the feeding process. Because the ends and shapes of the stud fastener shanks are extremely similar, the mechanical feeding mechanism often leads to incorrect orientation of the parts during sorting. If a part is misoriented and then fed into the threading die, the resulting threaded part will, at best, have substandard shape or dimensions. In severe cases, it can damage the machine's transmission mechanism, requiring major repairs. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides a visual recognition mechanism for loading stud fasteners.
[0004] The technical solution of the utility model is: a visual recognition mechanism for stud fastener feeding, comprising:
[0005] A frame, a vibrating loading tray is provided on the frame, a loading track is provided on the vibrating loading tray; a detection track is provided in communication with the loading track; a detection mechanism is provided on one side of the vibrating loading tray, the detection mechanism comprising:
[0006] A detection bracket is vertically arranged, and a camera is arranged on the detection bracket, and the camera faces the detection track;
[0007] A detection pusher, which is arranged outside the detection track and has a working end extending into the interior of the detection track;
[0008] A detection chassis is communicatively connected to the detection pusher and the camera, and detection software is set in the detection chassis, and the detection software is visual recognition software.
[0009] Furthermore, the detection mechanism further includes a detection light source, which is located directly below the camera and faces the detection track. By setting the detection light source, the success rate of detection can be improved and detection errors caused by insufficient light can be avoided.
[0010] Furthermore, the camera is a CCD industrial camera. This effectively reduces costs and allows for better adaptation to the detection mechanism during subsequent repairs and replacements. The fanless industrial vision camera is equipped with a fanless heat dissipation design, making it suitable for use in harsh environments.
[0011] Furthermore, the detection bracket includes a detection upright pole, the detection upright pole being arranged vertically, a detection crossbar mounted on the detection upright pole via a fixing clamp, and a detection element mounted on the detection crossbar. Generally, the camera and detection light source are arranged to ensure that they are both vertically and horizontally arranged. The specific angle and height can be adjusted according to actual needs. The height can be adjusted according to the clarity of the image, thereby ensuring stable imaging.
[0012] Furthermore, the fixing clamp is a cross fixing clamp. The setting of the cross fixing clamp can ensure stability in vertical and horizontal directions, and the angle and height can be adjusted according to actual conditions.
[0013] Furthermore, the inspection pusher can be any one of an inspection cylinder, an inspection electric cylinder, an inspection hydraulic cylinder, an inspection blower, or an inspection motor. Generally speaking, an inspection electric cylinder can be used, with the drive end of the inspection cylinder, inspection electric cylinder, or inspection hydraulic cylinder extending into the inspection track to push out unqualified products. When using an inspection blower, it is necessary to ensure that the wind force can push the product out of the inspection track, and it can work in conjunction with a solenoid valve. This method of blowing parts with wind can reduce the modification of existing mechanisms. When using an inspection motor, it is necessary to provide a lever at the end of the motor's conveyor shaft to move the workpiece and push it off the inspection track.
[0014] Further, the detection pusher is located just below the camera head. This is a common setting position, and at this moment, it is necessary to ensure timely identification and push work.
[0015] Furthermore, the detection pusher is located behind the detection position. Generally speaking, it only needs to be one position away from the detection position. After the camera completes the detection, the visual recognition software needs a certain amount of time to perform a comparison. If it fails, a signal is transmitted to the detection pusher, which can improve the efficiency of the detection and ensure that the detection can be carried out continuously.
[0016] Furthermore, the detection chassis is also communicatively connected to a detection display screen. The setting of the detection display screen can effectively display the detection process and detection quantity, can facilitate the user to make reasonable adjustments, and ensure reasonable work efficiency.
[0017] Furthermore, the visual recognition software includes:
[0018] A storage module having built-in qualified sample photos;
[0019] A temporary storage module, wherein the temporary storage module stores photos taken by the camera;
[0020] A comparison module, which compares the captured photo with the sample photo and transmits the comparison result;
[0021] If the result is qualified, no operating signal is output; if the result is unqualified, an operating signal is transmitted to the detection pusher, which receives the detection signal and pushes the sample off the detection track. The control logic of visual recognition software is a common control method and is generally purchased off-the-shelf. The specific setting of recognition points needs to be adjusted according to actual conditions.
[0022] Furthermore, the camera takes a picture of the inspection track again to determine whether to push the unqualified sample off the inspection track.
[0023] Furthermore, the feeding track is arranged in a spiral shape, which can effectively improve the feeding stability of the stud fasteners.
[0024] The beneficial technical effect of the present utility model is as follows: an independent detection mechanism is set on one side of the vibrating loading tray, and the detection mechanism is set independently without changing the original structure of the vibrating loading tray, which can realize the identification of parts with the wrong direction while vibrating loading, and send a signal through the system to push the material and re-sort it, and exclude the stud fasteners that do not conform to the conveying direction, so as to ensure that the direction of the conveyed stud fasteners is completely consistent. The device has a simple structure, high reliability and low cost. It is characterized by 100% accurate identification of incorrectly sorted parts through the use of high-definition cameras and AI systems. It can effectively prevent incorrectly sorted parts from entering the mold, avoiding economic losses caused by rework of large quantities of parts and damage to equipment. At the same time, the independent setting of this detection mechanism can be applied to the same type of part recognition scenarios, which is convenient for modular assembly and improves the efficiency of the detection mechanism.

[0045] Furthermore, camera 6 is a CCD industrial camera. This effectively reduces costs and allows for better adaptation to the inspection mechanism during subsequent repairs and replacements. Equipped with a fanless industrial vision camera, the fanless heat dissipation design allows it to be used in harsh environments.
[0046] Furthermore, the detection bracket 5 includes a detection upright 51, which is arranged vertically. A detection crossbar 53 is mounted on the detection upright 51 via a fixing clamp 52, and a detection element is mounted on the detection crossbar 53. Generally, the camera 6 and the detection light source 9 are arranged to ensure that they are both vertically and horizontally arranged. The specific angle and height can be adjusted according to actual needs. The height can be adjusted according to the clarity of the image, thereby ensuring stable imaging.

Generally speaking, an inspection electric cylinder can be used, and the driving end of the inspection cylinder, inspection electric cylinder, or inspection oil cylinder extends into the inspection track 4 to push out unqualified products. When using an inspection blower, it is necessary to ensure that the wind force can push the product out of the inspection track 4, and it can work in conjunction with a solenoid valve. This method of blowing parts with wind force can reduce the modification of existing mechanisms.

It is characterized by 100% accurate identification of incorrectly sorted parts through a high-definition camera in conjunction with an AI system. It can effectively prevent incorrectly sorted parts from entering the mold, avoiding economic losses caused by rework of large quantities of parts and damage to equipment.
