Description

Technical Field

[0001] This invention relates to the field of magnetic tile testing technology, specifically to a device for testing the flatness of the four corners of the arch height of magnetic tiles. Background Technology

[0002] Magnet tiles are a type of tile-shaped magnet used in permanent magnet motors, and the domestic production volume of magnet tiles is currently enormous. The raw materials are pre-fired at high temperature, then crushed into 5µm-8µm particles using a dry ball mill. These particles, along with iron oxide mixed with water and steel balls, are then ground into a slurry of 0.8µm-1.2µm using a wet ball mill. The slurry, with a water content controlled at approximately 35% using a sedimentation tower, is then oriented using a mold under a magnetic field. The slurry is then pressed into green blanks by a hydraulic press, sintered at high temperature to form semi-finished products, and finally ground to the required dimensions.

[0003] When green ceramic tiles are sintered at high temperatures, some tiles may exhibit corner warping, meaning the four corners at the bottom of the arch surface are often not on the same horizontal plane, resulting in defective products. Therefore, it is necessary to inspect the flatness of the four corners at the bottom of the arch surface of the formed ceramic tiles. Currently, the flatness inspection of the four corners of the arch surface relies on manual inspection. Manual inspection often results in missed or false detections, making it difficult to guarantee the quality of the ceramic tiles. Furthermore, the workload is large, the process is highly repetitive, and the inspection efficiency is low, making it impossible to perform batch automated inspection. This is no longer suitable for the needs of automated production of ceramic tiles and affects production efficiency. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide a device for detecting the flatness of the four corners of the arch height of magnetic tiles, so as to solve the problems of low efficiency, large error and inability to perform batch testing by manual inspection, which affect the production efficiency of magnetic tiles.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-5 As shown, this embodiment of the invention provides a device for detecting the flatness of the four corners of the arch height of magnetic tiles, including a feeding conveyor belt 1, a detection mechanism 2, and a discharging conveyor mechanism 3. The feeding conveyor belt 1 is driven by a motor, and the motor has a speed regulator that controls the transmission speed of the feeding conveyor belt 1. The feeding conveyor belt 1 sequentially conveys the magnetic tiles to be tested to the detection mechanism 2. The detection mechanism 2 detects the flatness of the four corners of the arch height of the magnetic tiles. The discharging conveyor mechanism 3 sequentially sends the tested tiles out of the detection mechanism 2, and separates the unqualified magnetic tiles from the qualified magnetic tiles. It can be understood that, in order to facilitate the overall control of the equipment by the operator, a PLC controller is set up. The feeding conveyor belt 1, the detection mechanism 2, and the discharging conveyor mechanism 3 are all electrically connected to the PLC controller. The operator can adjust the parameters of each mechanism through the PLC controller, so that the mechanisms cooperate with each other to achieve automatic operation. This is prior art and will not be described in detail here.

[0034] Using this equipment, the flatness of the four corners of the arch height of the magnetic tile can be automatically and systematically detected. It is suitable for large-scale automatic detection, which greatly facilitates production and improves detection efficiency.

[0035] like Figure 2As shown, in one embodiment of the present invention, the detection mechanism 2 includes a horizontal detection platform 21, dial indicators 22, and a limiting conveying device. The horizontal detection platform 21 is located below the discharge end of the feeding conveyor belt 1. The top surface of the horizontal detection platform 21 is machined to achieve a roughness of less than Ra0.04, and the top surface of the horizontal detection platform 21 smoothly transitions to the feeding end of the discharge conveyor mechanism 3. The sleeves of the four dial indicators 22 are respectively fixedly embedded in the through holes opened at the four corners of the horizontal detection platform 21, and the measuring heads of the four dial indicators 22 are all of the same size and protrude from the top surface of the horizontal detection platform 21. The measuring heads of the four dial indicators 22 correspond to the four corners of the arch height of the magnetic tile to be tested. The limiting conveying device is set between the horizontal detection platform 21 and the discharge end of the feeding conveyor belt 1. The limiting conveying device is used to cooperate with the feeding conveyor belt 1 to convey the magnetic tiles to be tested one by one to the top surface of the horizontal detection platform 21 for testing.

[0036] During testing, the feeding conveyor belt 1, in conjunction with the limiting conveyor device, transports the magnetic tile to be tested to the top surface of the horizontal testing platform 21. The four corners of the arch height of the magnetic tile to be tested are pressed against the measuring heads of four dial indicators 22. If the displayed values ​​of the four dial indicators 22 are all within the tolerance range of the drawing, the flatness of the four corners of the arch height of the magnetic tile is qualified and it is classified as a genuine magnetic tile. If the displayed values ​​of one or more dial indicators 22 are not within the tolerance range of the drawing, the flatness of the four corners of the arch height of the magnetic tile is unqualified and it is classified as a defective magnetic tile.

[0037] like Figure 3 As shown, in one embodiment of the present invention, the limiting conveying device includes a magnetic tile passing plate 23, a U-shaped baffle 24, a conveying mechanism 25, and a photoelectric proximity switch 26. The magnetic tile passing plate 23 is aligned with the discharge end of the feeding conveyor belt 1, and a magnetic tile passing port is opened on the magnetic tile passing plate 23. The gap between the four sides of the magnetic tile passing port and the four sides of the magnetic tile to be tested does not exceed 2mm. The U-shaped baffle 24 is disposed on the top of the magnetic tile passing plate 23, and the opening side of the U-shaped baffle 24 is aligned with the discharge end of the feeding conveyor belt 1. The photoelectric proximity switch 26 is disposed at the front end of the U-shaped baffle 24 and is communicatively connected to the conveying mechanism 25. The conveying mechanism 25 is disposed between the magnetic tile passing plate 23 and the horizontal detection table 21, and is used to convey the magnetic tiles to be tested one by one from the magnetic tile passing port to the top surface of the horizontal detection table 21.

[0038] The conveying mechanism 25 includes a guide cylinder 251, a movable partition 252, a fixed guide rod 253, and a folding guide rod 254. The movable partition 252 is fixedly mounted on the telescopic end of the guide cylinder 251 and can slide against the bottom of the magnetic tile passage plate 23. Figure 4As shown, multiple fixed guide rods 253 and one folding guide rod 254 are disposed on the top surface of the horizontal detection platform 21, forming a guide channel adapted to the magnetic tile directly below the magnetic tile passage. The folding guide rod 254 is aligned with the feeding end of the discharge conveying mechanism 3. The folding guide rod 254 includes an upper fixed rod 2541 and a lower movable rod 2542, which are movably connected by a movable joint 2543.

[0039] After the magnetic tile to be tested is transported to the magnetic tile passage opening on the magnetic tile passage plate 23, the photoelectric proximity switch 26 inside the C-shaped baffle 24 receives a signal and sends the signal to the guide cylinder 251. The guide cylinder 251 retracts, pulling the movable partition 252 back from the bottom of the magnetic tile passage plate 23, connecting the magnetic tile passage opening with the guide channel. The magnetic tile to be tested then falls automatically from the guide channel onto the top surface of the horizontal testing platform 21. Figure 5 As shown, the arch height of the tile to be tested is measured by pressing the four corners of the four dial gauges 22.

[0040] Combination Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the discharge conveying mechanism 3 includes a push cylinder 31 and a discharge conveyor belt 32 disposed opposite to each other on both sides of the horizontal inspection platform 21. The push cylinder 31 is used to push the inspected magnetic tiles onto the discharge conveyor belt 32. The discharge conveying mechanism 3 also includes a good product stacking plate 33, which is disposed directly below the discharge end of the discharge conveying mechanism 3. The discharge conveying mechanism 3 also includes a defective product ejection cylinder 34 and a defective product stacking plate 35, which are disposed opposite to each other on both sides of the feed end of the discharge conveyor belt 32. The defective product ejection cylinder 34 is used to push the unqualified magnetic tiles onto the defective product stacking plate 35.

[0041] The working process of this invention:

[0042] First, the staff debugs the equipment using the PLC controller. After debugging, the equipment is started. The staff places the magnetic tiles to be tested one by one at point A on the feeding conveyor belt 1. The feeding conveyor belt 1 transports the magnetic tiles to be tested at point A to point B inside the C-shaped baffle 24 according to the set requirements. At this time, the photoelectric proximity switch 26 receives the signal and sends the signal to the guide cylinder 251. The guide cylinder 251 retracts, pulling the movable baffle 252 back from the bottom of the magnetic tile passage plate 23, so that the magnetic tile passage is connected to the guide channel. The magnetic tile to be tested falls from point B through the guide channel to point C on the top surface of the horizontal testing table 21. The four corners of the arch height of the magnetic tile are pressed against the measuring heads of four dial indicators 22 for measurement and testing. After the test, the push cylinder 31 pushes the tested magnetic tile to the feed end D of the discharge conveyor belt 32. If the flatness of the four corners of the arch height of the magnetic tile is not up to standard, the defective product ejection cylinder 34 is activated to push the defective magnetic tile to the defective product stacking plate 35E. If the flatness of the four corners of the arch height of the magnetic tile is up to standard, the discharge conveyor belt 32 transports the good magnetic tile to the good product stacking plate 33F. The good magnetic tile flips 90° under its own weight and falls to the good product stacking plate 33F. The magnetic tiles are automatically and neatly arranged on the good product stacking plate 33.
