[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1 to 4 A rivet detection and screening device includes: a screening box 1, with a discharge door 101 installed on the side wall of the screening box 1; a screening and impurity removal mechanism 2, which includes a screening screen 201, a stirring assembly 3, and a support assembly 4, wherein the bottom of the screening screen 201 is installed on the inner wall of the screening box 1 through the support assembly 4, and the stirring assembly 3 is installed in the middle of the screening screen 201; and a weighing mechanism 7, which is located at the bottom of the screening box 1, for weighing the rivets after screening and impurity removal.

[0022] The support assembly 4 includes several support blocks 401, several chutes 402, several support rods 403, and several springs 404. The sidewalls of the several support blocks 401 are evenly distributed and fixedly connected to the inner wall of the screening box 1. Several chutes 402 are respectively opened on the top of several support blocks 401. Several support rods 403 are slidably connected to the top of several support blocks 401 by engaging with several chutes 402. The bottom of the screening screen plate 201 is fixedly connected to the top of several support rods 403. The two ends of several springs 404 are fixedly connected to the bottom of the screening screen plate 201 and the top of several support blocks 401, respectively.

[0023] The mixing assembly 3 includes several mixing rods 301, several mixing plates 302, a drive unit 5, and several gyratory units 6. One end of each mixing rod 301 is installed in the middle of the screen plate 201 through the drive unit 5, and one end of each mixing plate 302 is installed on the side wall of each mixing rod 301 through the gyratory units 6.

[0024] The drive unit 5 includes a motor 501, a support shaft 502, and a fixing block 503. The motor 501 is fixedly connected to the bottom center of the screen plate 201. One end of the support shaft 502 is fixedly connected to the output end of the motor 501 by rotating through the middle of the screen plate 201. The bottom of the fixing block 503 is fixedly connected to the other end of the support shaft 502. One end of several stirring rods 301 is symmetrically fixedly connected to the side wall of the fixing block 503.

[0025] The rotary unit 6 includes a rotating frame 601, a rotating block 602, and two torsion springs 603. The bottom of the rotating frame 601 is fixedly connected to the side wall of the stirring rod 301. One end of the stirring plate 302 is rotatably connected to the middle of the rotating frame 601 through the rotating block 602. The two ends of the two torsion springs 603 are fixedly connected to the side wall of the rotating frame 601 and the side wall of the rotating block 602, respectively.

[0026] In the specific implementation process, firstly, randomly selected rivets are loaded into the screening box 1. Then, the screening mesh 201 filters and separates impurities such as metal fragments mixed in with the rivets. Simultaneously, the control system starts the motor 501, which provides force to drive the connected support shaft 502 to rotate in the middle of the screening mesh 201. The rotation of the support shaft 502 drives the connected fixing block 503 to rotate as well. The rotation of the fixing block 503 drives the connected stirring rod 301 to rotate as well. As the pull studs rotate, the stirring rod 301 rotates, which in turn causes the stirring plate 302 to rotate under force. The rotating plate 302 then contacts and collides with the pull studs, causing it to rotate through the rotating block 602 in the center of the rotating frame 601. During rotation, the uneven distribution of the pull studs causes uneven force on the stirring plate 302. The torsion spring 603 provides a reaction force, causing the rotating block 602 to rotate in the center of the rotating frame 601. The rotating block 602 rotates, causing the connected agitator plate 302 to rotate as well. This rotation of the agitator plate 302 further impacts and disperses the contacting rivets, quickly separating metal fragments and other impurities from them. Furthermore, the operation of the motor 501 inevitably generates vibration. This vibration causes the connected screening screen plate 201 to slide up and down within the groove 402 at the top of the support block 401 via the support rod 403 at its bottom. The vibration is simply buffered by the spring 404, and the reaction force of the spring 404 increases the amplitude of the screening screen 201. At this time, the vibration of the screening screen 201 allows metal scraps and other impurities to be quickly filtered and separated by the screening screen 201. This enables automatic and rapid filtration and separation of metal scraps and other impurities mixed in the rivets according to the needs of use, eliminating the need for manual screening and removal. The operation is simple, convenient, time-saving, and labor-saving, effectively improving work efficiency and the accuracy of the final rivet test results.

[0027] Furthermore, after filtering and separating impurities such as metal scraps, the screening box 1 can be opened by opening the unloading door 101 that is hinged or snap-fitted on one side. At this time, the impurities separated by screening can be collected and cleaned out from the screening box 1 by opening the screening box 1.

[0028] Furthermore, the weighing mechanism 7 includes several support columns 701, several pressure sensors 702, and a data display screen 703. The tops of the support columns 701 are fixedly connected to the bottom of the screening box 1 through several pressure sensors 702, and the data display screen 703 is installed on the side wall of the screening box 1.

[0029] Based on the above embodiments, after the impurities separated by screening are removed from the screening box 1, the pressure sensor 702 is activated to detect the weight of the rivets contained in the screening box 1. After the processor analyzes and processes the data signal, the data can be displayed on the data display screen 703. By comparing the weight data when the box is empty with the weight data after the rivets are filled, the weight data of the rivets can be obtained. This allows for direct detection of the weight of the rivets after impurity removal according to usage needs, eliminating the need for other equipment and effectively improving the usability.

[0030] The working principle of the rivet detection and screening device provided by this utility model is as follows:

[0031] In use, firstly, randomly selected rivets are loaded into the screening box 1. Then, the screening mesh 201 filters and separates impurities such as metal fragments mixed in with the rivets. Simultaneously, the control system starts the motor 501, which provides force to drive the connected support shaft 502 to rotate in the middle of the screening mesh 201. The rotation of the support shaft 502 drives the connected fixing block 503 to rotate as well. The rotation of the fixing block 503 drives the connected stirring rod 301 to rotate as well, agitating the rivets. The rotation of the stirring rod 301 further drives the stirring plate 302 to rotate as well, allowing the stirring plate 302 to come into contact with and collide with the rivets. This allows the mixing plate 302 to rotate in the center of the rotating frame 601 under the force of the rotating block 602. During rotation, the uneven distribution of the rivets causes uneven force on the mixing plate 302. The torsion spring 603 provides a reaction force, causing the rotating block 602 to rotate in the center of the rotating frame 601. This rotation of the rotating block 602 drives the connected mixing plate 302 to rotate as well. The rotation and cyclical movement of the mixing plate 302 further disperses the contacting rivets, quickly separating metal fragments and other impurities from them. Furthermore, the operation of the motor 501 inevitably generates vibration, which... The movement causes the connected screening screen 201 to slide and vibrate up and down within the groove 402 at the top of the support block 401 via its bottom support slide rod 403. The vibration force is simply buffered by the spring 404, and the reaction force of the spring 404 increases the amplitude of the screening screen 201. At this time, the vibration of the screening screen 201 allows metal scraps and other impurities to be quickly filtered and separated. This achieves efficient and rapid automatic filtering and separation of metal scraps and other impurities trapped in the rivets according to usage needs, eliminating the need for manual screening. The operation is simple, convenient, time-saving, and labor-saving, effectively improving work efficiency and the accuracy of the final rivet inspection results. The purpose is twofold: firstly, to filter and separate impurities such as metal scraps; secondly, to open the screening box 1 by opening the hinged or snap-fit ​​discharge door 101 on one side. This allows the separated impurities to be collected and removed from the screening box 1. Then, by activating the pressure sensor 702, the weight of the rivets contained in the screening box 1 is detected. The data signal is analyzed and processed by the processor and displayed on the data display screen 703. By comparing the weight data of the empty box with the weight data after filling it with rivets, the weight data of the rivets can be obtained. This allows for effective and convenient direct detection of the weight of the rivets after impurity removal, according to usage requirements.This eliminates the need for additional testing equipment, effectively improving usability.
