Description

Technical Field

[0001] The invention relates to the technical field of ball cleaning, and in particular to a device for batch cleaning stains on the surface of highly reflective small-diameter balls. Background Art

[0002] Ball bearings are widely used general-purpose mechanical products. They are generally steel balls or ceramic balls. The ball is a sphere and is in great demand. The quality of its surface directly affects the service life of the bearing. Therefore, it is necessary to inspect the surface of the roller bearing for defects before it is put into production.

[0003] At present, when visually inspecting the surface defects of highly reflective small-diameter spheres, the inevitable dust, fingerprints or other stains on the surface of the sphere directly affect the judgment of the inspection results. Therefore, the surface of the sphere needs to be cleaned before inspection. Conventional cleaning methods are mostly to manually wipe the surface of the sphere with a dust-free cloth. Since the size of ball bearings is relatively small, even with a diameter of only 3mm, the cleaning workload is huge and the efficiency is not high. Summary of the invention

[0004] The purpose of the present invention is to propose a batch cleaning device suitable for the surface of highly reflective small-diameter spheres to address the shortcomings of the prior art. The device has a simple structural design and a simple operation process. Compared with the traditional manual dust-free cloth wiping method, it greatly improves the cleaning rate of the surface of small-diameter spheres, lays the foundation for the subsequent visual inspection of global surface defects of reflective small-diameter spheres, improves the detection accuracy, reduces the misjudgment rate, increases reliability, and fills the gap in the lack of automated and batch cleaning equipment for the surface of small-diameter spheres.

[0005] The technical solution to achieve the purpose of the present invention is:

[0006] A batch cleaning device for stains on the surface of a highly reflective small-diameter sphere comprises a driving assembly, a trough that is fixedly arranged obliquely, and a first material tray, a second material tray, a third material tray, and a fourth material tray that are arranged in the trough and are spaced from top to bottom in parallel with the bottom of the trough, wherein the first material tray and the third material tray are both coaxially fixedly connected to the output end of the driving assembly, a ball feeding hole suitable for the passage of a small ball is provided on the first material tray, a plurality of ball rotation holes suitable for the passage of a small ball are uniformly provided on the third material tray along the circumferential direction, and the spacing between the third material tray and the second material tray and the fourth material tray is between the radius and the diameter of the small ball to be measured; the second material tray and the fourth material tray are both fixedly arranged and are respectively provided with a goal hole and a ball outlet hole suitable for the passage of a small ball and having no overlapping areas therebetween, the goal hole is located at the lowest point of the second material tray and is located on the same circumferential surface as the ball rotation hole and the ball outlet hole, a cleaning assembly suitable for surface cleaning of the ball in the ball rotation hole is provided between the third material tray and the second material tray and the fourth material tray, and a ball outlet tube is provided at the bottom of the trough, and the ball outlet tube is connected to the ball outlet hole.

[0007] Furthermore, the distance between the outer peripheral surface of the first material tray and the inner wall of the material trough is smaller than the diameter of the ball to be tested.

[0008] Furthermore, the distance between the outer side of the ball delivery hole and the side wall of the trough is smaller than the radius of the ball to be tested.

[0009] Furthermore, the diameters of the ball delivery hole, the ball rotation hole, the ball entry hole and the ball exit hole are all less than twice the diameter of the ball to be tested.

[0010] Furthermore, the distance between the first material tray and the second material tray is between one and two times the diameter of the ball to be tested.

[0011] Furthermore, the cleaning component is an arc-shaped brush fixedly mounted on the opposite surface of the second material tray or the fourth material tray, and the brush is located on the same circumferential surface as the ball entry hole or the ball outlet hole.

[0012] Furthermore, two ends of the two brushes extend to both sides of the ball inlet and the ball outlet respectively.

[0013] Furthermore, the distance between the ball entry hole and the ball exit hole along the circumferential direction is greater than the diameter of the ball to be tested.

[0014] Furthermore, the driving assembly includes a fixedly installed motor, and a coupling and a rotating shaft are fixedly connected to one side of the output shaft of the motor. The rotating shaft is coaxially fixedly connected to the first material tray and the third material tray, and is coaxially rotationally connected to the second material tray and the fourth material tray.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects:

[0016] The present invention drives the first material tray and the third material tray to rotate simultaneously through a driving component. When the small ball to be tested is poured into the material trough, the ball feeding hole follows the first material tray to make a circular motion to send the small ball to be tested to the second material tray. Due to its own weight, the small ball to be tested rolls to the lowest point, and then falls into the rotating ball hole of the third material tray through the ball entering hole, and follows the rotating ball hole to make a circular motion. At the same time, the cleaning component cleans the surface of the rotating small ball. When the rotating ball hole containing the small ball to be tested overlaps with the ball outlet hole, the small ball to be tested automatically falls into the ball outlet hole and is then discharged through the ball outlet pipe to complete automatic cleaning. The structural design is simple and the operation process is simple. The batch cleaning of stains on the surface of highly reflective small-diameter spheres is realized. Compared with the traditional manual dust-free cloth wiping method, the surface cleaning rate of small-diameter spheres is greatly improved, which lays a foundation for the subsequent visual inspection of global surface defects of reflective small-diameter spheres, improves the detection accuracy, reduces the misjudgment rate, increases the reliability, and fills the gap of no automation and batch cleaning equipment on the surface of small-diameter spheres.

[0017] The present invention limits the distance between the outer peripheral surface of the first material tray and the inner wall of the material trough to be smaller than the diameter of the small ball to be tested, thereby preventing the ball from being stuck or directly falling into the bottom of the material trough, ensuring that each small ball to be tested can flow through the cleaning component to achieve automatic cleaning.

[0018] The present invention limits the distance between the outer side of the ball feeding hole and the side wall of the material trough to be smaller than the radius of the small ball to be tested, thereby ensuring that a small number of small balls, even when there is only one left, can smoothly pass through the ball feeding hole into the next layer without manual intervention.

[0019] The present invention limits the diameters of the ball feeding hole, the ball rotating hole, the ball entry hole and the ball exit hole to be less than twice the diameter of the ball to be tested, thereby preventing two balls from entering at the same time and causing the balls to get stuck and block each channel, thereby improving the operating stability of the device.

[0020] The present invention limits the distance between the first material tray and the second material tray to be between one and two times the diameter of the small ball to be measured, thereby avoiding ball jamming and ensuring that the material tray can rotate smoothly.

[0021] The cleaning component of the present invention adopts an arc-shaped brush, has a simple structure and is low in cost.

[0022] The present invention maximizes the cleaning area and further improves the cleaning effect by limiting the positions of the two ends of the brush. At the same time, the brush is softer than the material tray, which avoids surface wear caused by friction between the small ball to be tested and the fourth material tray at the bottom.

[0023] The distance between the goal hole and the ball outlet hole in the circumferential direction of the present invention is greater than the diameter of the ball to be tested, so as to avoid that when the spacing between the material trays is large, the distance between the goal hole and the ball outlet hole is too close. The diameter of the ball to be tested in the goal hole directly falls into the ball outlet hole through the ball rotating hole, thereby ensuring that each ball to be tested is cleaned.

[0024] The driving assembly of the invention drives the material tray to rotate through a motor, has a simple structure and rotates smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] (Example 1)

[0037] like Figures 1 to 3 The device for batch cleaning of stains on the surface of highly reflective small-diameter spheres shown in the figure comprises a driving assembly 1, a material trough 2, a first material tray 3, a second material tray 4, a third material tray 5 and a fourth material tray 6. The material trough 2 is a cylindrical structure and is fixedly arranged at an angle. The first material tray 3, the second material tray 4, the third material tray 5 and the fourth material tray 6 are all oblate structures, arranged in the material trough 2 and arranged in parallel with the bottom of the material trough 2 from top to bottom. The driving assembly 1 comprises a motor 1-1, a coupling 1-2 and a rotating shaft 1-3, the motor 1-1 is fixedly arranged, the output shaft is fixedly connected to the rotating shaft 1-3 through the coupling 1-2, the first material tray 3 and the third material tray 5 are both coaxially fixedly connected to the rotating shaft 1-3, the second material tray 4 and the fourth material tray 6 are fixedly arranged and are both rotatably connected to the rotating shaft 1-3.

[0038] A ball delivery hole 3-1 is provided on the first material tray 3, a ball scoring hole 4-1 is provided on the second material tray 4, a plurality of ball rotation holes 5-1 are uniformly provided along the circumference of the third material tray 5, and a ball outlet hole 6-1 is provided on the fourth material tray 6. The ball delivery hole 3-1, the ball scoring hole 4-1, the ball rotation hole 5-1 and the ball outlet hole 6-1 are all suitable for small balls to pass through, and the ball scoring hole 4-1, the ball rotation hole 5-1 and the ball outlet hole 6-1 are located on the same circumferential surface, and the ball scoring hole 4-1 is located at the lowest point of the second material tray 4, and does not overlap with the projection of the ball outlet hole 6-1 along the axial direction. The motor 1-1 drives the rotating shaft 1-3 to rotate, thereby driving the first material tray 3 and the third material tray 5 to rotate at the same time. When the ball to be tested is poured into the material trough 2, the ball feeding hole 3-1 follows the first material tray 3 to make a circular motion, and sends the ball to be tested to the second material tray 4. The ball to be tested rolls to the lowest point due to its own weight, and then falls into the ball rotating hole 5-1 of the third material tray 5 through the ball entering hole 4-1.

[0039] The spacing between the third material tray 5 and the second material tray 4 and the fourth material tray 6 is between the radius and diameter of the ball to be tested, so the ball to be tested is trapped by the rotating ball hole 5-1, and thus follows the rotating ball hole 5-1 to make a circular motion. The second material tray 4 and the fourth material tray 6 are respectively fixed with arc-shaped brushes 7 located on the same circumferential surface as the rotating ball hole 5-1 on one side facing the third material tray 5, as a cleaning component, to clean the surface of the rotating ball to be tested. When the rotating ball hole 5-1 containing the ball to be tested rotates to overlap with the ball outlet hole 6-1, the ball to be tested automatically falls into the ball outlet hole 6-1. In order to avoid a situation where the distance between the ball holes 4-1 and the ball outlet holes 6-1 is too close when the spacing between the material trays is large, the diameter of the ball to be tested in the ball hole 4-1 falls directly into the ball outlet hole 6-1 through the ball rotating hole 5-1. In this embodiment, the distance between the ball hole 4-1 and the ball outlet hole 6-1 along the circumferential direction is greater than the diameter of the ball to be tested, ensuring that each ball to be tested is cleaned.

[0040] A ball outlet pipe 2-1 is provided at the bottom of the trough 2, and the ball outlet pipe 2-1 is connected to the ball outlet hole 6-1, and the ball to be tested is discharged through the ball outlet pipe 2-1 to complete automatic cleaning. The two ends of the two brushes 7 extend to both sides of the ball entry hole 4-1 and the ball outlet hole 6-1, respectively, to maximize the cleaning area and further improve the cleaning effect. At the same time, the brush 7 is relatively soft relative to the material tray, which avoids direct friction between the ball to be tested and the fourth material tray 6 at the bottom to cause surface wear. The overall structural design is simple and the operation process is simple, which realizes batch cleaning of stains on the surface of highly reflective small-diameter spheres. Compared with the traditional manual dust-free cloth wiping method, it greatly improves the cleaning rate of the small-diameter sphere surface, lays the foundation for the subsequent visual inspection of the global surface defects of the reflective small-diameter sphere, improves the detection accuracy, reduces the misjudgment rate, and increases reliability, filling the gap of the lack of automated and batch cleaning equipment for the surface of small-diameter spheres.

[0041] In order to avoid ball jamming, the diameters of the ball feeding hole 3-1, the ball entry hole 4-1, the ball rotation hole 5-1 and the ball exit hole 6-1 of the present embodiment and the spacing between the first material tray 3 and the second material tray 4 are between one and two times the diameter of the ball to be tested. The distance between the outer circumference of the first material tray 3 and the inner wall of the material trough 2 is smaller than the diameter of the ball to be tested, which prevents the ball jamming and prevents the ball to be tested from falling directly into the bottom of the material trough 2, ensuring that each ball to be tested can flow through the cleaning component to achieve automatic cleaning.

[0042] In addition, the distance between the outer side of the ball delivery hole 3-1 of this embodiment and the side wall of the material trough 2 is smaller than the radius of the ball to be tested, ensuring that even when there are a small number of balls, or only one left, it can smoothly pass through the ball delivery hole 3-1 and enter the next layer without manual intervention.

[0043] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
