Description

Technical Field

[0001] This utility model relates to the field of magnetic tile processing, and in particular to a device for quickly removing low-strength magnetic tiles. Background Technology

[0002] The manufacturing process of magnetic tiles is similar to that of ceramics, involving three steps: wet molding, high-temperature sintering, and grinding. During production, invisible micro-cracks may develop inside the magnetic tiles, while small chips and breaks may occur on the outside. Stress concentration occurs at these cracks and breaks, reducing the compressive strength of the magnetic tiles. In the upstream motor assembly process, low-strength magnetic tiles are prone to cracking due to the internal stress propagating along the crack direction caused by rapid heating and cooling during injection molding, or due to excessive assembly force. This reduces product quality and production efficiency for customers. Therefore, it is crucial to quickly and effectively remove these low-strength magnetic tiles during production.

[0003] Such minute cracks and chipping damage cannot be completely avoided in the industry. Currently, the commonly used method for quickly identifying low-strength magnetic tiles is to pass each tile through a static press. However, the effective pressure of a static press is generally only 100-800N, which is limited and cannot effectively identify magnetic tiles with a compressive strength greater than that of the static press. Other methods include two-color flaw detection and ultrasonic flaw detection, but due to their high cost and low efficiency, they cannot be applied to the inspection of large quantities of magnetic tiles. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology, which has high cost and low efficiency in identifying minute cracks and broken pieces on magnetic tiles and cannot be applied to the inspection of large batches of magnetic tiles, and to provide a device for quickly rejecting low-strength magnetic tiles.

[0005] The technical solution adopted by this utility model to solve its technical problem is a device for quickly removing low-strength magnetic tiles, including a lifting platform, a sliding positioning module, a sensor, a load-bearing pushing module, and a push rod; one side of the bottom end of the sliding positioning module is unsupported, and multiple magnetic tiles are placed in a row on the sliding positioning module; the push rod is located on the sliding positioning module to push the magnetic tiles to the side with no bottom support; the sliding positioning module is located on the top of the lifting platform; the sensor is installed on the sliding positioning module to sense whether there are magnetic tiles; the load-bearing pushing module is located on the side of the bottom end of the sliding positioning module with no bottom support, and the sensor and the load-bearing pushing module are located on the same side of the sliding positioning module; the push rod pushes the magnetic tiles to move towards the sensor; when the sensor senses the magnetic tiles, the magnetic tiles are pushed to the load-bearing pushing module; the load-bearing pushing module pushes the magnetic tiles, causing the magnetic tiles to suspend in the air and fall onto the lifting platform.

[0006] Furthermore, the lifting platform includes a drop platform, a collection platform, and a lifting rod for lifting. The drop platform and the collection platform are fixedly connected to each other, and the lifting rod is installed on the drop platform. The magnetic tile falls directly from the suspended position onto the drop platform.

[0007] Furthermore, the sliding positioning module includes a base plate, a middle plate, and a side plate. The middle plate and the side plate are arranged parallel to each other and placed on top of the base plate to form a moving track for the magnetic tile.

[0008] Furthermore, the sliding positioning module also includes a blocking plate, which is arranged perpendicularly to the middle plate. The sensor is mounted on the middle plate or the blocking plate. The length of the bottom plate is less than the length of the middle plate and the side plate so that one side of the bottom of the sliding positioning module is unsupported.

[0009] Furthermore, the side plates are provided in two symmetrical configurations and are located on both sides of the middle plate.

[0010] Furthermore, the sensor is an infrared sensor.

[0011] Furthermore, the bearing and pushing module includes a pushing cylinder and a bearing plate. The pushing cylinder is connected to the bearing plate, and when the telescopic rod of the pushing cylinder extends, the bearing plate covers the unsupported part of the sliding positioning module.

[0012] This utility model has the following beneficial technical effects:

[0013] This invention uses a push rod to move the magnetic tile, causing it to fall at the end of the sliding positioning module. As the magnetic tile falls, it cracks along the direction of the crack, thus enabling drop detection of each magnetic tile and removing those with internal cracks or defects. The structure is simple, low-cost, and highly efficient. The width is adjustable, making it suitable for magnetic tiles of various shapes. The falling direction can be precisely controlled, effectively removing magnetic tiles with internal cracks or defects. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] Reference Figure 1 This embodiment includes a lifting platform 1, a sliding positioning module 2, a sensor 3, a load-bearing pushing module 4, and a push rod 5. The sliding positioning module 2 and the load-bearing pushing module 4 are placed on the lifting platform 1, and the sensor 3 and the push rod 5 are both located on the sliding positioning module 2. In this embodiment, there is another mounting frame as the base for installation, so as to provide a position for the sliding positioning module 2, the load-bearing pushing module 4, and the lifting platform 1 to be installed and fixed.

[0022] Reference Figure 1 and Figure 2 The lifting platform 1 includes a drop platform 11, a collection platform 12, and a lifting rod 13 for lifting. The drop platform 11 and the collection platform 12 are fixedly connected to each other, and the lifting rod 13 is connected to the drop platform 11. In addition, the drop platform 11 has a collection cylinder 14 to push the fallen magnetic tile 6 into the collection platform 12. In this embodiment, the lifting rod 13 consists of two long rods and a fixing plate. The two long rods are hinged to each other at the center position. The two ends of one long rod are fixed to the drop platform 11 and the fixing plate, and the two ends of the other long rod are fixed to the other long rod. The magnetic tile 6 slides within grooves on the drop platform 11 and the fixed plate. In another embodiment, the lifting rod 13 is a cylinder or a telescopic rod. The sliding positioning module 2 is located above the drop platform 11. The magnetic tile 6 falls from the sliding positioning module 2 onto the drop platform 11. Because the magnetic tile 6 is a typical brittle material, it indicates that it undergoes almost no plastic deformation under stress and instead fractures directly. Fracture mechanics studies have shown that there is a critical stress intensity factor. When the stress factor at the crack tip reaches or exceeds the critical value of the material, the crack will undergo unstable propagation. At the moment of impact when the magnetic tile 6 falls, the load is applied rapidly, and the stress intensity factor at the crack tip easily reaches the critical value, causing cracking along the crack direction.

[0023] Reference Figure 3 and Figure 4The sliding positioning module 2 includes a base plate 21, a middle plate 22, side plates 23, and a blocking plate 24. Two side plates 23 are symmetrically arranged on the left and right sides of the middle plate 22. The middle plate 22 and the two side plates 23 are parallel to each other and have the same length. The middle plate 22 and the side plates 23 are perpendicular to the base plate 21. The middle plate 22 and the side plates 23 form a moving track for the magnetic tile 6. The length difference between the base plate 21 and the middle plate 22 is slightly greater than the length of the magnetic tile 6. One end of the base plate 21 is flush with the middle plate 22, leaving the other end unsupported. The blocking plate 24 is located on the unsupported side of the sliding positioning module 2 and is perpendicular to both the middle plate 22 and the base plate 21. There is a protrusion on the blocking plate 24 or the middle plate 22 with a through groove. The sensor 3 is limited to the through groove to sense whether the magnetic tile 6 is present. The push rod 5 is located on the other end of the sliding positioning module 2 relative to the blocking plate 24, and pushes the magnetic tile 6 to move within the moving track.

[0024] Reference Figure 1 and Figure 2 The supporting and pushing module 4 is located on the unsupported side of the sliding positioning module 2. Specifically, it includes a pushing cylinder 41 and a supporting plate 42. The pushing cylinder 41 and the supporting plate 42 are connected to each other. When the telescopic rod of the pushing cylinder 41 extends, the supporting plate 42 covers the unsupported part of the sliding positioning module 2. The push rod 5 pushes the magnetic tile 6 to the surface of the supporting plate 42. At this time, the sensor 3 senses the magnetic tile 6 and sends a signal to the pushing cylinder 41, causing the telescopic rod of the pushing cylinder 41 to retract. The magnetic tile 6 is blocked by the blocking plate 24 and cannot retract with the supporting plate 42, thus falling onto the drop platform 11. Subsequently, it is pushed into the collection platform 12 by the collection cylinder 14 for collection. In addition to being set along the direction of the moving track, the supporting and pushing module 4 can also be set perpendicular to the direction of the moving track. In the case of vertical setting, the side plate 23 blocks the movement of the magnetic tile 6.

[0025] In this embodiment, the sensor 3 is an infrared sensor 3, and includes, but is not limited to, distance and visual sensing.
