[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0025] like Figures 1-6 As shown, the present invention provides a feeding and testing device for counting steel rings, including a feeding conveyor line 1, a testing component located at the station after the feeding conveyor line 1, and a roller brush 32 component 3 located above the feeding conveyor line 1.

[0026] This solution is mainly used for counting and packaging steel rings with a diameter of 15-70mm. The roller brush assembly 3 is located after the hopper. Material enters from the hopper onto the feeding conveyor line 1, and then the roller brush assembly 3 rotates, spreading the material evenly on the feeding conveyor line 1. Next, it is conveyed to the detection assembly via the feeding conveyor line 1, where mixed materials are detected to remove materials with unacceptable diameters and foreign objects. Materials that pass the detection continue to be conveyed forward to the counting and packaging station for counting and packaging.

[0027] The roller brush assembly 3 adopts a structure commonly used in existing technology, which includes a mounting frame 31, a roller brush 32, a height adjustment assembly 33, and a roller brush drive unit 34. The height adjustment assembly 33 mainly includes a hand crank and a gear module. Rotating the hand crank transmits power, thereby adjusting the height of the roller brush 32. Here, the height of the roller brush 32 is fixed for materials of the same specification. The roller brush drive unit 34 mainly includes a motor, a belt, and a pulley module, which is used to drive the roller brush 32 to rotate and disperse the material.

[0028] The feeding conveyor line 1 includes a frame 11, a main conveyor body 12 mounted on the frame 11, and a supplementary conveyor body located on one side of the main conveyor body 12. The width of the main conveyor body 12 is greater than the width of the supplementary conveyor body. The detection component includes a backlight belt assembly 4 and a vision camera module 6 mounted on the backlight belt assembly 4.

[0029] In the above scheme, the material, after being dispersed and spread by the roller brush assembly 3, is conveyed forward through the main conveyor line 12. A small portion of the material enters the replenishment conveyor line. The main conveyor line 12 and the replenishment conveyor line together convey the material onto the backlight belt. The transition plate 7 set between the feeding conveyor line 1 and the backlight belt assembly 4 allows the material to be smoothly conveyed onto the backlight belt assembly 4. The replenishment conveyor line can replenish material during counting to ensure more accurate counting. How to replenish material will be discussed below.

[0030] The replenishment conveyor line includes a reverse conveyor line 13, a forward conveyor line 14, and a material distribution assembly. The reverse conveyor line 13 is located between the main conveyor line 12 and the forward conveyor line 14, and the rotation direction of the forward conveyor line 14 is the same as that of the main conveyor line 12. Materials are mainly conveyed by the main conveyor line 12. Because the main conveyor line 12 and the reverse conveyor line 13 are adjacent, some of the material on the main conveyor line 12 will enter the reverse conveyor line 13. After being dispersed by the material distribution assembly, the material enters the forward conveyor line 14 in a single row. This allows for sequential replenishment during subsequent replenishment, ensuring replenishment accuracy.

[0031] The material distribution assembly includes a first material distribution block 15, a second material distribution block 16, and a material distribution plate 17. The first material distribution block 15 and the second material distribution block 16 are arranged sequentially along the material conveying direction. The material distribution plate 17 is located at the intersection of the reverse conveying line 13 and the forward conveying line 14 and is located on the side of the second material distribution block 16. An inlet 18 for material passage is formed between the first material distribution block 15 and the material distribution plate 17.

[0032] In the above scheme, both material distribution block 15 and material distribution block 2 16 are wedge-shaped blocks. Material distribution block 15 is located above the reversing conveyor line 13, and material distribution block 2 16 is located on the main conveyor line 12 and close to the reversing conveyor line. When the material on the main conveyor line 12 is conveyed to the position of material distribution block 2 16, it will be blocked by the inclined surface of material distribution block 2 16. Since the material is in a ring shape, it will move along the inclined surface to the reversing conveyor line 13 after being blocked. At the same time, under the obstruction of the material distribution plate 17, it is conveyed back along the reversing conveyor line 13 and comes into contact with material distribution block 15. Then, it enters the forward conveyor line 14 in sequence through the obstruction of the inclined surface of material distribution block 15 and is arranged in a single row on the forward conveyor line 14.

[0033] To ensure that materials can be arranged in a single row, an adjustment assembly 2 is installed on the side frame of the frame 11 to adjust the width of the material conveying channel of the forward-rotating conveyor line 14. The adjustment assembly 2 includes an adjustment support 21, an adjustment plate 22 slidably mounted on the adjustment support 21, and a hand-cranked screw module 23 connected to the adjustment plate 22. During adjustment, by rotating the hand-cranked screw module 23, the screw rotates, causing the adjustment plate 22 to move linearly on the adjustment support 21. The adjustment plate 22 and the material distribution plate 17 together form the material conveying channel of the forward-rotating conveyor line 14. The adjustment movement fixes the position of the material distribution plate 17, thereby realizing the width adjustment of the material conveying channel to accommodate the conveying of materials with different diameters.

[0034] The backlight belt assembly 4 includes a belt drive 41, a light-transmitting belt 42 disposed on the belt drive 41, and a surface light source assembly 43 located below the light-transmitting belt 42. The surface light source assembly 43 is located below the light-transmitting belt 42, which ensures that the light source shines through the belt onto the material on the belt surface, making the material outline clearer. A vision camera module 6 located above the light-transmitting belt 42 performs image detection. The vision camera is an area array camera, a commonly used defect detection camera in the prior art, working in conjunction with a host computer to detect materials or foreign objects of different sizes mixed in. A cleaning roller brush 5 is provided at the bottom of the backlight belt assembly 4 for cleaning the surface of the backlight belt, preventing contamination of the material.

[0035] The feeding process during counting in this scheme is as follows:

[0036] The material is conveyed to the backlight belt assembly 4 through the feeding conveyor line 1. Mixing detection is performed on the backlight belt assembly 4. If an abnormality is detected, the equipment stops running, and the mixed material or foreign object is removed manually. Then the equipment is restarted. If there is no abnormality, the counting work continues. If the target count is 200, initially, the main conveyor line 12, the reverse conveyor line 13, and the forward conveyor line 14 are all running. The main conveyor line 12 and the forward conveyor line 14 feed material onto the backlight belt assembly 4. When the count at the counting station reaches the set value S1 (e.g., 170), the main conveyor line 12, the reverse conveyor line 13, and the forward conveyor line 14 all stop. Then, the backlight belt assembly 4 rotates one belt length, feeding the material on the belt surface into the counting device for replenishment (e.g., replenishing 25 items). If 5 more items need to be replenished, the reverse conveyor line 13 and the forward conveyor line 14 operate simultaneously, replenishing 5 items onto the conveyor belt via the forward conveyor line 14, which then transports them to the counting station, completing the counting of one bag. Then, the feeding conveyor line 1 starts again to count the next bag. The number of items counted per bag and the set value S1 are not unique and are set according to the usage requirements.

[0037] This solution can be used for conveying and detecting foreign objects in steel ring-like materials. Through the combined feeding conveyor line 1, along with the roller brush assembly 32, material dispersion and stable conveying can be achieved. Compared to vibratory conveying, it solves the problem of excessive noise from metal-to-metal impacts. Furthermore, during conveying, precise replenishment can be achieved through the supplementary conveyor line, improving counting accuracy. Material detection components are used before counting to prevent mixing of materials and foreign objects, thus improving product qualification rate.
