Description

Technical Field

[0001] This utility model relates to the field of magnetic tile testing technology, and in particular to a novel magnetic tile testing platform. Background Technology

[0002] Magnet tiles are magnetic components widely used in motors, loudspeakers, and other fields, and their quality directly affects product performance. Currently, the testing of magnet tiles is generally characterized by cumbersome procedures and low efficiency.

[0003] Traditional inspection methods rely heavily on manual labor, which is not only labor-intensive and subjective but also prone to missed inspections. Existing automated inspection equipment typically uses specific positioning seats or clamps to hold and position the magnetic tiles to inspect each surface. This method requires precise positioning mechanisms, makes loading and unloading the magnetic tiles difficult, and requires changing the positioning seat for different specifications of magnetic tiles, resulting in poor versatility and high costs. Furthermore, after inspecting one surface, a robotic arm or flipping device is needed to pick up and flip the magnetic tile before placing it back on the positioning seat for the next surface inspection. This significantly increases the mechanical complexity and control difficulty of the equipment, and the flipping and secondary positioning processes can easily cause damage to the magnetic tiles, severely restricting the inspection cycle and affecting overall efficiency.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a new type of magnetic tile testing station to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content

[0006] To overcome the shortcomings of the prior art, the present invention aims to disclose a novel magnetic tile testing station to solve the problems of low efficiency, complex equipment, and easy product damage caused by the reliance on a dedicated positioning seat and the need for flipping operation in the prior art.

[0007] This utility model discloses a novel magnetic tile testing station, including a transparent turntable. The turntable is equipped with a rotary encoder. The outer circumference of the turntable is arranged in sequence along its rotation direction as a first guide unit, a second guide unit, an identification number unit, a lower end face detection unit, a first upper end face detection unit, a second upper end face detection unit, a lateral detection unit, a qualified product unloading unit, and a non-qualified product unloading unit.

[0008] The first guide unit includes a first guide bar disposed horizontally above the turntable. The guide surface of the first guide bar faces the outer side of the turntable, and the distance between the first guide bar and the edge of the turntable gradually decreases along the rotation direction and then remains constant.

[0009] The second guide unit includes a second guide bar positioned horizontally above the turntable. The guide surface of the second guide bar faces the inside of the turntable, and the distance between the guide bar and the edge of the turntable gradually increases along the rotation direction and then remains constant.

[0010] The height of the first guide bar and the second guide bar from the upper surface of the turntable is no greater than the height of the magnetic tile. The projection trajectory formed by the guide surfaces of the first guide bar and the second guide bar when the turntable rotates together defines the conveying channel of the magnetic tile. The width of the conveying channel is no greater than the length of the magnetic tile. Through the cooperation of the first guide unit and the second guide unit, the magnetic tile is accurately guided and positioned on the turntable, ensuring the accuracy of subsequent testing and eliminating the need for a dedicated positioning seat.

[0011] The magnetic tile inspection station also includes a control unit, which is connected to the rotary encoder, counting unit, lower end face inspection unit, first upper end face inspection unit, second upper end face inspection unit, lateral inspection unit, qualified product unloading unit, and unqualified product unloading unit. This control unit coordinates the operation of each unit to achieve automated inspection and sorting.

[0012] A preferred technical solution: The lower end face detection unit includes a first detection camera and a first detection light source located below the turntable. It is used to detect whether there are quality defects on the lower end face of the magnetic tile.

[0013] Preferred technical solution: The first upper surface detection unit includes a second detection camera located above the turntable and a first calibration plate located below the turntable. It is used to detect whether the forward edge dimensions of the magnetic tile are within acceptable limits.

[0014] Preferred technical solution: The second upper surface detection unit includes a third detection camera and a second detection light source located above the turntable. It is used to detect whether there are quality defects on the upper surface of the magnetic tile.

[0015] A preferred technical solution: The lateral detection unit includes a fourth detection camera located on the outside of the turntable and a second calibration plate located on the inside of the turntable. It is used to detect whether the lateral dimensions of the magnetic tiles are within acceptable limits.

[0016] Preferred technical solution: The qualified product unloading unit includes a qualified product collection bin that connects the inlet to the edge of the turntable, and a first jet pipe located on the opposite side of the qualified product collection bin. Qualified products are blown from the turntable into the qualified product collection bin by airflow.

[0017] Preferred technical solution: A qualified product conveying pipe is installed at the bottom of the qualified product collection bin. This facilitates the conveying of qualified products to the next process.

[0018] Preferred technical solution: The non-conforming product unloading unit includes a non-conforming product collection bin that connects the inlet to the edge of the turntable, and a second jet pipe located on the opposite side of the non-conforming product collection bin. Non-conforming products are blown from the turntable into the non-conforming product collection bin by airflow.

[0019] Preferred technical solution: The bottom of the non-conforming product collection bin is equipped with a non-conforming product conveying pipe. This facilitates the collection of non-conforming products.

[0020] Preferred technical solution: A pending product unloading unit is further provided on the outer periphery of the turntable, following the direction of rotation, behind the non-conforming product unloading unit. The pending product unloading unit includes a pending product collection bin connected to the edge of the turntable at the inlet, and a third air jet pipe located opposite the pending product collection bin. This is used to collect and process magnetic tiles with uncertain test results.

[0021] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0022] This invention achieves automatic and precise positioning of magnetic tiles through a combination of turntable conveyor and a unique guiding unit, completely eliminating the need for dedicated positioning seats and clamps, thus improving equipment versatility and loading / unloading efficiency. By arranging the lower, upper, and side detection units sequentially around the turntable, and using a transparent turntable, all surfaces of the magnetic tile can be inspected in a single rotation, completely avoiding cumbersome flipping operations, simplifying the equipment structure, improving inspection efficiency, and preventing product damage that may result from flipping. Integrated control via a control unit enables automated inspection and sorting, reducing manual intervention, lowering production costs, and ensuring a continuous and smooth inspection process. The inclusion of qualified, unqualified, and pending product unloading units enables automatic classification and collection of magnetic tiles, facilitating subsequent processing.

[0036] Example:

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model discloses a novel magnetic tile inspection station, including a motor-driven turntable 1. The turntable 1 is made of transparent material and is equipped with a rotary encoder for real-time monitoring of the rotation angle and speed of the turntable 1. Along the rotation direction, the outer periphery of the turntable 1 is sequentially arranged with a first guide unit 2, a second guide unit 3, an identification numbering unit 4, a lower end face detection unit 5, a first upper end face detection unit 6, a second upper end face detection unit 7, a lateral detection unit 8, a qualified product unloading unit 9, a defective product unloading unit 10, and a pending product unloading unit 11. It also includes a control unit, which can be a PLC or an industrial computer, and is signal-connected to the rotary encoder, identification numbering unit 4, lower end face detection unit 5, first upper end face detection unit 6, second upper end face detection unit 7, lateral detection unit 8, qualified product unloading unit 9, defective product unloading unit 10, and pending product unloading unit 11. The main components of this utility model will be described in detail below:

[0038] The first guide unit 2 includes a first guide bar 21, which is horizontally positioned above the turntable 1 with its guide surface facing the outer side of the turntable 1. The distance between the guide bar 21 and the edge of the turntable 1 gradually decreases and then remains constant along the rotation direction. The second guide unit 3 includes a second guide bar 31, which is horizontally positioned above the turntable 1 with its guide surface facing the inner side of the turntable 1. The distance between the guide bar 31 and the edge of the turntable 1 gradually increases and then remains constant along the rotation direction. The height of both the first guide bar 21 and the second guide bar 31 from the upper surface of the turntable 1 is no greater than the height of the magnetic tile, thus ensuring that the magnetic tile does not enter the gap between the guide bar and the turntable during transport. The projection trajectory formed by the guide surfaces of the first guide bar 21 and the second guide bar 31 when the turntable 1 rotates together defines a transport channel with a width no greater than the length of the magnetic tile, allowing the magnetic tile to be gradually corrected in position on the turntable, i.e., the axis of the magnetic tile is parallel to the tangent of the turntable 1.

[0039] The identification numbering unit 4 can be a photoelectric sensor or a proximity switch, used to count the number of passing magnetic tiles and send the signal to the control unit for numbering, so as to facilitate corresponding recording with subsequent detection results.

[0040] The lower end face detection unit 5 includes a first detection camera 51 and a first detection light source 52 located below the turntable 1. The first detection light source 52 provides illumination, and the first detection camera 51 captures images of the lower end face of the magnetic tile. The control unit analyzes the images to detect defects such as cracks or stains.

[0041] The first upper surface detection unit 6 includes a second detection camera 61 located above the turntable 1 and a first calibration plate 62 located below the turntable 1. It is used to confirm whether the forward contour dimensions of the magnetic tile are qualified. It should be noted that "forward" here refers to the outer contour of the magnetic tile when it is laid flat, not the front and back sides of the magnetic tile itself.

[0042] The second upper surface detection unit 7 includes a third detection camera 71 disposed above the turntable 1 and a second detection light source 72 disposed above the turntable 1. The second detection light source 72 illuminates from above, and the third detection camera 71 supplements the image of the upper surface of the magnetic tile. The control unit analyzes the image to detect defects such as cracks or stains.

[0043] The lateral inspection unit 8 includes a fourth inspection camera 81 located on the outside of the turntable 1 and a second calibration plate 82 located on the inside of the turntable 1. The fourth inspection camera 81 captures lateral surface images of the magnetic tile to confirm whether the lateral dimensions of the magnetic tile are qualified, with its main inspection dimension being the height.

[0044] The qualified product unloading unit 9 includes a qualified product collection bin 91 and a first air jet pipe 92. The inlet of the qualified product collection bin 91 is connected to the edge of the turntable 1, and the first air jet pipe 92 is located on the opposite side of the qualified product collection bin 91. When the control unit determines that the magnetic tile is a qualified product based on the detection result, the first air jet pipe 92 sprays air to blow the magnetic tile into the qualified product collection bin 91. The bottom of the qualified product collection bin 91 is provided with a qualified product conveying pipe 93 for conveying qualified products to packaging or the next process.

[0045] The defective product unloading unit 10 includes a defective product collection bin 101 and a second air jet pipe 102. The inlet of the defective product collection bin 101 is connected to the edge of the turntable 1, and the second air jet pipe 102 is correspondingly located on the opposite side of the defective product collection bin 101. When a magnetic tile is detected as defective, the second air jet pipe 102 ejects airflow to blow the magnetic tile into the defective product collection bin 101. The bottom of the defective product collection bin 101 is provided with a defective product conveying pipe 103 for collecting defective products.

[0046] The pending product unloading unit 11 includes a pending product collection bin 111 and a third jet pipe 112. The inlet of the pending product collection bin 111 is connected to the edge of the turntable 1, and the third jet pipe 112 is correspondingly located on the opposite side of the pending product collection bin 111. When the test result is uncertain, the third jet pipe 112 blows the magnetic tile into the pending product collection bin 111 for subsequent manual re-inspection.

[0047] Work process:

[0048] The magnetic tiles are fed into turntable 1 by upstream equipment and rotate with turntable 1. They first pass through the first guide unit 2 and the second guide unit 3, and are positioned correctly in the conveyor channel. Identification and numbering unit 4 records the number of magnetic tiles and assigns them numbers. Subsequently, the magnetic tiles sequentially pass through the lower end face detection unit 5, the first upper end face detection unit 6, the second upper end face detection unit 7, and the side detection unit 8 for comprehensive inspection. The control unit controls the operation of the qualified product unloading unit 9, the unqualified product unloading unit 10, or the pending product unloading unit 11 based on the inspection results, completing automatic sorting. Throughout the process, a rotary encoder ensures the precise stopping position of turntable 1, ensuring that each magnetic tile is inspected at the correct station.

[0049] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
