Description

Technical Field

[0001] This utility model belongs to the field of iron filings detection technology, specifically relating to an iron filings detection device on the surface of a starter shaft. Background Technology

[0002] In machining processes, especially after grinding and turning of precision parts such as starter shafts, residual iron filings on the workpiece surface can not only affect the quality of subsequent processes but also potentially damage equipment. Therefore, developing a reliable iron filings detection device for starter shaft surfaces is of paramount importance.

[0003] Currently, an existing iron removal device for mining machinery with dual conveyor belt induction (publication number CN214864372U) includes an iron removal machine. The iron removal machine comprises a frame, a first conveyor belt, a second conveyor belt, and two symmetrical fixed frames. A metal detector is installed inside the first conveyor belt, and a scraper is installed on the outer surface of the second conveyor belt. A placement box is located at one end of each fixed frame. The placement box includes an iron plate, a first chamber, and a second chamber. A telescopic plate is installed inside the first chamber, and a strong magnet is installed inside the second chamber. An opening is provided on the outer surface of the placement box. This utility model, by setting up the first and second conveyor belts, fixed frames, placement box, iron plate, telescopic plate, strong magnet, scraper, and metal detector, achieves the function of removing iron and other metals from the mineral to be ironed, while simultaneously removing iron filings from the surface of the iron removal equipment.

[0004] However, there is a problem: the solution is designed for iron filings that adhere to the surface, but it does not distinguish iron filings embedded in the shaft surface, which cannot be separated by a magnet. Utility Model Content

[0005] This solution provides a device for detecting iron filings on the surface of a starter shaft, which solves the problem of being unable to distinguish which iron filings cannot be separated by a magnet.

[0006] To solve this problem, this solution provides a device for detecting iron filings on the surface of a starter shaft, comprising:

[0007] Conveyor belt: Used to transport the starter shaft;

[0008] Impurity removal mechanism: used to remove iron filings from the outer surface of the starter shaft;

[0009] High-definition camera inspection instrument: used to detect whether the starter shaft contains iron filings;

[0010] The impurity removal mechanism includes an impurity removal housing and an electromagnet. The impurity removal housing is fixedly connected to the conveyor belt, and the electromagnet is fixedly connected to the impurity removal housing, with the electromagnet aligned with the conveyor belt. The starting shaft first passes through the impurity removal mechanism and then through a high-definition camera detector.

[0011] The principle of this solution is as follows: the starting shaft is placed on a conveyor belt. The conveyor belt starts running, smoothly transporting the workpiece forward. The workpiece first passes through a cleaning mechanism installed on the conveyor belt. An electromagnet in the cleaning mechanism is energized, generating a strong magnetic field. Under the action of the magnetic field, magnetic iron filings adsorbed on the outer surface of the starting shaft are attracted and removed.

[0012] The starter shaft then enters the high-definition camera inspection area. After initial impurity removal, the starter shaft continues forward into the working range of the high-definition camera inspection system. The camera inspects the surface of the starter shaft. If iron filings are still present, they are likely embedded in the shaft surface and are difficult to clean, requiring manual removal by specialized personnel. At this point, the high-definition camera inspection system analyzes the signal to determine if any abnormalities are detected. If an abnormality is detected, the high-definition camera inspection system will issue an alarm.

[0013] The beneficial effects of this solution are as follows: by first using an electromagnet to remove the iron filings adhering to the shaft surface, and then using a high-definition camera to detect whether there are embedded iron filings on the shaft surface, the problem of iron filings on the shaft surface is eliminated as much as possible, thus improving the finished quality of the starter shaft.

[0014] Furthermore, it also includes a swing arm, which is rotatably connected to the impurity removal housing and is engaged with the start-up shaft.

[0015] When the starter shaft is conveyed into the cleaning housing, the electromagnet will attract iron filings on the upper surface of the starter shaft, while iron filings on the lower surface of the starter shaft are not easily attracted.

[0016] To solve this problem, when the starting shaft is conveyed to the inside of the impurity removal housing, the starting shaft will contact the swing arm. The swing arm will slightly resist the movement of the starting shaft, causing the conveyor belt and the starting shaft to move relative to each other. Under the friction of the conveyor belt, the starting shaft will rotate, so that the iron filings on all surfaces of the starting shaft can be attracted by the electromagnet.

[0017] When the next starting shaft arrives, the thrust of both shafts will cause the swing arm to rotate, allowing the first starting shaft to pass, and the next starting shaft will continue the above operation.

[0018] This mechanism ensures that iron filings are attracted to all surfaces by electromagnets through the rotation of the starter shaft. This significantly improves the iron filings removal rate, especially solving the problem of iron filings on the lower surface that are difficult to handle with traditional methods.

[0019] Furthermore, it also includes a sticky ball, which is fixedly connected to the end of the swing rod and cooperates with the start-up shaft.

[0020] When the next starting shaft arrives, the thrust of both shafts will cause the swing arm to rotate, allowing the first starting shaft to pass, or possibly both starting shafts to pass at the same time, which may result in some starting shafts being unable to flip.

[0021] The swing arm in this mechanism can swing even with just one starting shaft. When the starting shaft enters the impurity removal housing, it comes into contact with the sticky ball, which adheres to its surface. Driven by the conveyor belt, the starting shaft pushes the swing arm aside, causing it to rotate. Simultaneously, the sticky ball rotates as well. As the starting shaft advances, the adhered portion of the sticky ball is pulled, causing the starting shaft to rotate at a certain angle. Although this rotation is limited (e.g., 90°~180°), it is sufficient to flip the surface that was originally located below to the top, allowing it to enter the electromagnet's attraction area. In this way, the lower surface of the starting shaft flips to the top.

[0022] Once the sticky ball reaches its maximum stretch or rotation angle, it automatically detaches from the starting shaft due to weakened material elasticity or adhesion. The swing arm returns to its original position, ready to receive the next starting shaft.

[0023] The sticky ball provides initial adhesion, which can trigger the swing arm action and cause the flip even if there is only one starting shaft. This avoids the problem that some starting shafts cannot flip when two starting shafts pass through at the same time.

[0024] Furthermore, the conveyor belt includes a belt, a support, rollers, and a motor. The rollers are rotatably connected to the support, the motor is fixedly connected to the support, the motor shaft is fixedly connected to the rollers, and the belt cooperates with the rollers.

[0025] When the motor is powered on, it begins to rotate, driving the rollers connected to it to rotate. As the rollers rotate, the friction between them and the belt causes the belt to move along a predetermined path. The starter shaft, placed on the belt, moves forward along with the belt, passing through processing stages such as a cleanup mechanism and a high-definition camera inspection device.

[0026] Furthermore, it also includes guardrails, which are fixedly connected to the brackets and are used in conjunction with a high-definition camera inspection device.

[0027] Guardrails, typically made of sturdy metal, are installed on both sides and above the conveyor belt, ensuring a secure connection to the support structure. Located on either side of the high-definition camera inspection unit, the guardrails primarily prevent accidental entry of external objects into the inspection area and also prevent interference from the external environment.

[0028] Furthermore, it also includes a collection mechanism, which includes a collection box, a fan, and a ventilation duct. The collection box is fixedly connected to the support, one end of the ventilation duct is connected to the impurity removal shell, and the other end is connected to the collection box. The fan is used to suck the iron filings inside the impurity removal shell into the collection box.

[0029] After the test is completed, the fan starts, creating a high-speed airflow and a localized negative pressure environment within the ventilation duct. When the electromagnet is de-energized, the air pressure inside the cleaning casing decreases, causing air to flow from the outside to the inside, carrying iron filings into the ventilation duct.

[0030] Iron filings are carried by the airflow into the ventilation duct and eventually transported to the collection box. The collection box is equipped with a filter that separates the iron filings from the air, allowing clean air to escape while the iron filings remain inside the box.

[0031] This facility utilizes negative pressure airflow generated by a blower to quickly remove iron filings attracted by electromagnets, reducing manual cleaning time and improving automation. Simultaneously, the iron filings are collected and reused in metal smelting or recycling systems.

[0032] Furthermore, it also includes a fixed suction cup, which is fixedly connected to the bracket. The fixed suction cup provides additional grip, ensuring the stability of the entire device.

[0033] Furthermore, it also includes a controller, which is fixed on a bracket, and the fan, motor, high-definition camera detector, and electromagnet are all electrically connected to the controller. All actuators are centrally managed by a single controller, improving the intelligence level of the equipment and simplifying the operation process. Attached Figure Description

[0037] As attached Figure 1 As shown:

[0038] This solution provides a device for detecting iron filings on the surface of a starter shaft, including a conveyor belt 1, a cleaning mechanism, a high-definition camera detector 4, and a collection mechanism. The conveyor belt 1 includes a belt, a support 9, rollers 11, and a motor 2. A suction cup 10 is provided at the bottom of the support 9 to stabilize its position. The support 9 is rotatably connected to the rollers 11, and there are two rollers 11 located on the same horizontal line. A belt is wrapped around the two rollers 11.

[0039] Motor 2 is fixed on bracket 9. The shaft of motor 2 is coaxially fixedly connected to the right roller 11. The belt runs from left to right.

[0040] The impurity removal mechanism is located to the left of the high-definition camera inspection unit 4, ensuring that the starter shaft 12 passes through the impurity removal mechanism before passing through the high-definition camera inspection unit 4. The high-definition camera inspection unit 4 is fixedly connected to the bracket 9. Guardrails 3 are provided on both sides of the high-definition camera inspection unit 4 to prevent environmental or personnel interference. The high-definition camera inspection unit 4 is equipped with an alarm to alert staff to any difficult-to-handle starter shaft 12. A supplementary light is also provided on the conveyor belt 1 to provide supplementary lighting for the high-definition camera.

[0041] The controller 6 is fixed on the bracket 9, and the fan, motor 2, high-definition camera detector 4 and electromagnet 15 are all electrically connected to the controller 6.

[0042] As attached Figure 1 , Figure 2 As shown:

[0043] The impurity removal mechanism includes an impurity removal housing 5, an electromagnet 15, a swing arm 14, and a sticky ball 13. The impurity removal housing 5 is a door frame type, and the electromagnet 15 is installed inside the housing 5. The electromagnet 15 is aligned with the belt of the conveyor belt 1. The swing arm 14 is rotatably connected to the inside of the housing 5. The sticky ball 13 is fixedly connected to the lower end of the swing arm 14. The sticky ball 13 is made of surface-treated silicone and has a certain degree of stickiness. The length of the swing arm 14 is set according to the height of the starter shaft 12. Those skilled in the art can replace the swing arm 14 with a suitable length for starter shafts 12 of different diameters, so that the swing arm 14 and the sticky ball 13 can contact the starter shaft 12.

[0044] The collection mechanism includes a collection box 7, a fan, and a ventilation duct 8. The collection box 7 is fixed on the bracket 9. The upper end of the collection box 7 is connected to the ventilation duct 8. The side of the collection box 7 is equipped with a filter screen that prevents iron filings from passing through but allows air to pass through. The other end of the ventilation duct 8 is connected to the side of the impurity removal housing 5. The fan is installed inside the ventilation duct 8 to generate suction.

[0045] In actual operation, the material is fed into the conveyor belt 1 by the starting shaft 12. The starting shaft 12 is placed on the belt, and the controller 6 controls the motor 2 to drive the roller 11 to move the belt, so as to achieve smooth transportation.

[0046] The starting shaft 12 first enters the impurity removal housing 5. The controller 6 controls the electromagnet 15 to be energized to generate a magnetic field, which attracts magnetic iron filings on its surface. Then the starting shaft 12 will come into contact with the sticky ball 13, which will adhere to the surface of the starting shaft 12. Under the action of the conveyor belt 1, the starting shaft 12 pushes the swing rod 14 away, and the swing rod 14 rotates. At the same time, the sticky ball 13 will also rotate. As the starting shaft 12 moves forward, the part of the sticky ball 13 that is adhered to is pulled, causing the starting shaft 12 to rotate at a certain angle (such as 90°~180°), so that the originally downward-facing surface is also exposed to the range of action of the electromagnet 15, which then attracts the iron filings.

[0047] Then, axis 12 is activated to enter the high-definition camera detection area, where the high-definition camera performs real-time monitoring. If abnormal reflections are detected (such as embedded iron filings or incomplete removal), the system will issue an alarm.

[0048] After the test is completed, the controller 6 controls the fan to start, creating a negative pressure airflow in the ventilation duct 8, which sucks the loose iron filings inside the impurity removal shell 5 into the collection box 7 for centralized recycling, reducing manual cleaning and improving environmental protection and automation levels.

[0049] The beneficial effects of this solution are as follows: 1. By first using an electromagnet 15 to remove iron filings adhering to the shaft surface, and then using a high-definition camera inspection instrument 4 to detect whether there are embedded iron filings on the shaft surface, the problem of iron filings on the shaft surface is eliminated as much as possible, thus improving the finished product quality of the starter shaft 12. 2. The adhesive ball 13 provides initial adhesion force, so even if there is only one starter shaft 12, it can trigger the swing arm 14 to move and drive it to flip, avoiding the problem that if two starter shafts 12 pass through at the same time, some starter shafts 12 will not be able to flip.

[0050] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
