Description

Technical Field

[0001] This utility model relates to the field of hardware manufacturing and processing technology, specifically to an automatic sorting device for hardware size detection. Background Technology

[0002] During the production of hardware parts, due to various factors such as processing technology and equipment precision, the dimensions of the produced hardware parts may have certain deviations. In order to ensure product quality, it is necessary to inspect the dimensions of the hardware parts and sort the qualified products that meet the dimensional requirements from the unqualified products that do not.

[0003] Traditionally, the inspection and sorting of hardware parts is primarily done manually. Workers use measuring tools such as calipers and micrometers to measure the dimensions of each hardware part and then manually sort them based on the measurements. However, this method has many drawbacks. On the one hand, manual inspection is slow and inefficient, making it difficult to meet the needs of large-scale production and severely restricting production progress. On the other hand, manual inspection is easily affected by factors such as the inspector's experience, fatigue, and subjective judgment, leading to difficulties in ensuring the accuracy and consistency of the inspection results, and easily resulting in missed or incorrect inspections, thus affecting product quality.

[0004] Therefore, it is necessary to provide an automatic sorting device for hardware parts size detection to solve the above-mentioned technical problems. Utility Model Content

The adjusting block 13 slides on the first vertical rail 12 and is positioned by threaded connection between the wing bolt 16 and different positioning grooves 15, which can adapt to different material detection needs and improve detection accuracy and applicability.

[0034] In one preferred embodiment, the sorting mechanism 9 includes a second vertical rail 18, which is fixedly installed on the top of the sorting machine body 1 on one side of the fixed frame 10.

[0036] In one preferred embodiment, an arc-shaped guide plate 11 is fixedly installed on the back of a fixed frame 10, which can guide the material to move along a preset trajectory, making the sorting process smoother and more efficient.

[0037] In one embodiment, the baffle 6 is made of a transparent material that can both create a protective barrier between the work area and the sorting area to ensure personnel safety and allow staff to observe the sorting process in real time so as to respond promptly.

[0038] In one preferred embodiment, the movable block 21 has a threaded hole that matches the threaded rod 20, and the movable block 21 is threadedly connected to the threaded rod 20 through the threaded hole, which can convert the rotational motion of the threaded rod 20 into the linear motion of the movable block 21, thereby realizing the precise adjustment of the height of the electric telescopic rod 23.

[0039] In one embodiment, the sorting machine body 1 is equipped with a control system, which includes a central processing unit and an operation panel. The central processing unit is connected to the second servo motor 27, the laser displacement sensor 14, the first servo motor 19, and the electric telescopic rod 23. The control system of the sorting machine body 1 connects to each component through the central processing unit, which can realize centralized control and coordinated operation of the second servo motor 27, the laser displacement sensor 14, the first servo motor 19, and the electric telescopic rod 23, effectively improving the automation and accuracy of hardware sorting and inspection.

[0040] The working principle of this utility model is as follows: During the equipment commissioning phase, the completed hardware parts are transported in an orderly manner via the conveyor body 2 and accurately arrive at the sorting tray 3. Simultaneously, the second servo motor 27 is controlled and started. The drive end of this motor drives the first gear 25 to rotate. Through the precise meshing transmission between the first gear 25 and the second gear 26, the turntable 28 rotates in a circular motion. The rotation of the turntable 28 further drives the sorting tray 3 to rotate synchronously. The rotation of the sorting tray 3 allows the hardware parts transported thereon to be conveyed along a pre-set designated path. During the hardware part transport process, the height of the laser displacement sensor 14 needs to be adjusted in advance. Specifically, the wing bolt 16 is turned out of the corresponding positioning slot 15. At this time, the adjusting block 13, having lost the positioning function between the wing bolt 16 and the positioning slot 15, can freely adjust its vertical position on the first vertical rail 12. The laser displacement sensor 14 moves together with the adjusting block 13. After the laser displacement sensor 14 is adjusted to the appropriate detection height, tighten the wing bolt 16 to securely lock the position of the laser displacement sensor 14 by cooperating with the positioning groove 15. When the hardware part enters the detection range below the laser displacement sensor 14 along with the sorting tray 3, the laser displacement sensor 14 quickly performs high-precision detection on the height and width dimensions of the hardware part and transmits the relevant data to the central processing unit in a timely and accurate manner. The central processing unit performs detailed analysis and judgment on the received detection data according to the pre-set size standards. Before the hardware part is conveyed to the sorting mechanism 9, the working height of the electric telescopic rod 23 needs to be pre-adjusted according to the specific specifications of the hardware part. The specific operation process is as follows: control the drive end of the first servo motor 19 to drive the threaded rod 20 to rotate. With the help of the threaded transmission between the threaded rod 20 and the movable block 21, and the sliding guide relationship between the movable block 21 and the second vertical rail 18, the movable block 21 can move vertically stably. The movement of the movable block 21 drives the connecting arm 22 to move, thereby driving the electric telescopic rod 23 to move to the appropriate working height. When the hardware parts conveyed by the sorting plate 3 are determined to be unqualified products by the central processing unit, the central processing unit immediately issues a control command to drive the electric telescopic rod 23 to start working. The driving end of the electric telescopic rod 23 drives the push block 24 to move forward, pushing the unqualified hardware parts on the sorting plate 3 into the left unloading guide plate 7. If the hardware parts are qualified products, the sorting mechanism 9 will not perform the sorting action. The qualified hardware parts will continue to be conveyed along the conveying path and fall into the right unloading guide plate 7 under the guidance of the arc-shaped guide plate 11, thereby realizing continuous and efficient sorting of qualified and unqualified hardware parts.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
