AI Technical Summary
In existing technologies, the sorting accuracy of small springs is poor, which affects subsequent processes. In particular, small springs are prone to tangling and deformation, making it difficult to achieve efficient individual sorting.
A three-stage sorting logic is adopted: initial sorting by a vibratory feeder, further sorting by a centrifugal separation component, and detection by a vision sensor and feedback from an air nozzle. The vision sensor detects the small springs and compares them with standard parts. Qualified springs move along the track, while unqualified springs are blown back into the vibratory feeder hopper for re-sorting.
This significantly improves the sorting accuracy of small springs, ensures the accuracy of individual spring sorting, avoids spring tangling and deformation, and meets the requirements of subsequent processes.

Abstract
Description
Technical Field
[0001] This utility model pertains to spring sorting equipment, specifically a small spring sorting device for sorting small springs into individual units. Background Technology
[0002] Springs are mechanical parts that utilize elasticity and have many applications in daily life and production. However, because many springs are stacked together, and because their shape is helical with hooks, they easily become entangled under physical compression. Separating them is difficult, time-consuming, and laborious, and can easily deform or even destroy the springs, especially smaller ones. Currently, small springs are sorted using a single type of vibratory feeder. However, the sorted springs are often not individual units, resulting in poor sorting accuracy and affecting subsequent processes. Therefore, improvements to the vibratory feeder are needed to enhance its sorting accuracy and meet the requirements of subsequent processes. Utility Model Content
[0003] The purpose of this invention is to overcome the problem of low sorting quality of small springs in the prior art and to provide a small spring sorting device that can improve the sorting accuracy of small springs.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a small spring sorting device, including a vibratory plate, a centrifugal separation component for dispersing the spiral spring is connected in series in the middle and rear section of the spiral track of the vibratory plate, a visual sensor and an air nozzle with a control valve are provided above the rear section of the spiral track of the vibratory plate, the air nozzle is connected to an air source, and the vibratory plate, the centrifugal separation component, the visual sensor and the air nozzle are connected to a controller.
[0005] Optionally, the air nozzle consists of a stop air nozzle for stopping small springs and a sorting air nozzle for blowing unqualified small springs into the vibrating plate hopper.
[0006] Optionally, the centrifugal separation assembly mainly consists of a centrifugal chamber and a centrifugal disc. The centrifugal disc is placed horizontally inside the centrifugal chamber. A motor is fixed at the bottom of the centrifugal chamber and connected to the centrifugal disc. A baffle with a spiral pattern in its longitudinal section is placed on the centrifugal disc and is fixedly connected to the centrifugal chamber. The centrifugal chamber has an inlet and an outlet. The inlet is located directly above the middle of the baffle, and the outlet is located at the spiral end of the baffle. The spiral track of the vibrating disc is located in the middle of the centrifugal chamber and at the outlet. The outlet has a gathering chamber for gathering the small springs that have been thrown out to the spiral track.
[0007] The usage and principle of this utility model are as follows: Small spring materials are poured into the hopper of a vibrating plate. Under the action of the vibrating plate, the small springs rise along the spiral track to obtain preliminary sorting. Then, they enter the centrifugal separation component for further sorting. Next, a vision sensor detects the small springs and compares them with standard parts in the silo. Qualified small springs continue to move forward along the spiral track to the next process, while unqualified ones are blown back into the hopper of the vibrating plate by air nozzles for re-sorting. The three-level sorting logic of "vibrating plate preliminary sorting - centrifugal physical separation - visual secondary screening" is adopted to improve the sorting accuracy through multiple screenings.
[0008] Compared with the prior art, the present invention has at least the following beneficial effects: the present invention can effectively improve the sorting accuracy of small springs. Attached Figure Description
[0009] Figure 1 This is a side view of the structure of this utility model;
[0010] The components described in the attached diagram are labeled as follows: vibratory plate 1, centrifugal separation component 2, vision sensor 3, and air nozzle 4. Detailed Implementation
[0011] Example 1, in conjunction with the following Figure 1 To further illustrate this utility model, the small spring sorting device includes a vibratory plate 1. A centrifugal separation component 2 for dispersing the spiral springs is connected in series in the rear section of the spiral track of the vibratory plate. A vision sensor 3 and an air nozzle 4 with a control valve are provided above the rear section of the spiral track of the vibratory plate. The air nozzle is connected to an air source and consists of a stop air nozzle for stopping the small springs and a sorting air nozzle for blowing unqualified small springs into the hopper of the vibratory plate. By adjusting the blowing angle and blowing pressure of the air nozzle, the small springs can be stopped on the track and fall back into the hopper of the vibratory plate. The vibratory plate, the centrifugal separation component, the vision sensor and the air nozzle are connected to a controller, which coordinates and controls the operation of the entire process.
[0012] There are many forms of centrifugal separation components, as long as they can centrifuge and separate small springs. However, for ease of understanding, one form of centrifugal separation component is provided. This centrifugal separation component mainly consists of a centrifugal chamber and a centrifugal disc. The centrifugal disc is placed horizontally in the centrifugal chamber. A motor is fixed at the bottom of the centrifugal chamber and connected to the centrifugal disc. A baffle with a spiral pattern in its longitudinal section is placed on the centrifugal disc and is fixedly connected to the centrifugal chamber. The centrifugal chamber has an inlet and an outlet. The inlet is located directly above the middle of the baffle, and the outlet is located at the spiral end of the baffle. The spiral tracks of the vibrating disc are located in the middle of the centrifugal chamber and at the outlet. The outlet has a gathering chamber for gathering the small springs that have been thrown out to the spiral track.
