Description

Technical Field

[0001] The utility model relates to the technical field of magnetic block batch detection, in particular to a device for adjusting the position of magnetic blocks to be detected in magnetic block batch detection equipment. Background Art

[0002] Due to their reusable nature, magnets are widely used in consumer applications such as home entertainment, outdoor adventures, and educational toys. The most critical process in magnet production is magnetizing the bulk magnetic material. Consumer magnets are relatively small, and the dimensional accuracy of mass-produced magnets is often inconsistent. This results in some magnetic material failing to reach full saturation during magnetization, leading to magnetic flux leakage. This manifests as insufficient magnetic attraction. Therefore, magnetic testing is a crucial step in magnet production.

[0003] Existing magnetic detection solutions, such as those described in patent document CN113311371A, place a magnet chain consisting of multiple magnetic blocks within a magnet chain slot on a magnet chain mounting platform. A movable guide rail then drives the platform to move, allowing all the magnetic blocks in the chain to pass sequentially through a magnetic field sensor for magnetic detection. However, due to the scattered placement of the magnetic blocks in this existing technology, misalignment of the blocks can easily occur during movement, leading to errors. Utility Model Content

[0006] Furthermore, the gap between the two rollers in the pair of roller devices is slightly smaller than the width of the magnetic block to be transported.

[0007] Furthermore, the transmission channel is specifically a mouth-shaped structure composed of two left and right pieces that are embedded in each other. One of the two pieces is a horizontal bottom panel for supporting the magnetic block to be detected. When the two pieces are in the spliced state, the inner walls of the two pieces respectively press against the left and right sides of the magnetic block to be detected. The top and sides of the mouth-shaped structure are hollowed out to allow multiple driven rollers on both sides and the top of the transmission channel to enter the mouth-shaped structure from the hollowed-out areas to contact the magnetic block.

[0017] The present invention is further described in detail below in conjunction with specific embodiments.

[0018] The magnetic block batch detection device of this embodiment is as follows Figure 1 As shown, the system comprises a horizontal transmission channel for the magnetic blocks to be inspected. The entire transmission channel is composed of multiple sets of two cooperating components, each equipped with a transverse drive to move the components apart or together, thereby adjusting the width of the transmission channel to accommodate the width of the magnetic blocks. The system also includes a controller and, along the magnetic block transmission channel, a loading and shaping conveyor 1, a detection orientation adjustment device 2, a discharge and compacting conveyor 3, and a magnetic block rejection device 4, sequentially arranged along the magnetic block transmission direction. These devices are each connected to the controller of the magnetic block batch inspection equipment.

[0019] like Figure 2 and 3 As shown, a removable vertical baffle is installed at the head end of the transmission channel. Before testing, the baffle is removed. Batches of magnetic blocks C are placed into the transmission channel from the starting point S of the magnetic block batch testing equipment in an engaged state. These magnetic blocks C to be tested are placed in a continuous, long strip on the loading and shaping conveyor 1 at the beginning of the transmission channel. They are contacted laterally by the side adjustment mechanism 11 and vertically by the top adjustment mechanism 12. After all the magnetic blocks C to be tested have been placed in the first section of the transmission channel, the vertical baffle is installed to hold the outermost ends of the blocks. The loading and shaping conveyor 1 is used to limit and convey the batch of magnetic blocks at the top and sides, ensuring that the multiple magnetic blocks pass through the magnetic detector in the testing orientation adjustment device 2 in a neat and continuous manner. The magnetic detector detects the magnetism of each magnetic block and transmits the detected magnetic data to the controller. The controller is also connected to the display 0, which displays the magnetic data. The unloading and compacting conveyor 3 applies pressure to the passing magnetic block queue from both sides to ensure that adjacent magnetic blocks are tightly connected. The controller identifies unqualified magnetic blocks from the received magnetic data according to a preset program and sends an in-place signal of the unqualified magnetic blocks to the magnetic block rejection device 4. The magnetic block rejection device 4 is used to operate according to the received in-place signal to separate the magnetic block corresponding to the in-place signal from the continuous batch of magnetic blocks. A baffle is provided at a small distance from the end of the transmission channel, and the baffle is tilted in the direction of the transmission channel. The magnetic blocks that have not been separated from the batch of magnetic blocks are removed from the transmission channel from the end E of the magnetic block batch detection equipment as qualified magnetic blocks, and fall due to gravity or are blocked by the baffle and fall into the discharge chute below the end of the transmission channel.

[0020] like Figure 3 As shown, the feeding shaping conveying device 1 includes a magnetic block position adjustment device to be detected provided at the first section of the transmission channel, and the magnetic block position adjustment device to be detected includes a side adjustment mechanism 11 for lateral contact and a top adjustment mechanism 12. Figure 4 and 5As shown, the transmission channel is specifically a mouth-shaped structure composed of two interlocking left and right pieces 101 and 102. Of the two pieces, the left piece 101 is an L-shaped structure, with its horizontal bottom panel used to support the magnetic block C to be detected. The right piece 102 is an L-shaped structure rotated 180 degrees. When the two pieces 101 and 102 are in the assembled state, the inner side walls of the two pieces respectively abut the left and right sides of the magnetic block C to be detected. A vertical baffle 103 is installed at the head end of the transmission channel. The top of the vertical baffle 103 is provided with a horizontal protrusion. When installed, the vertical baffle 103 extends into the interior of the transmission channel mouth structure to abut the outermost ends of the magnetic blocks, thereby keeping the entire magnetic block array compact and not easily misaligned.

[0021] In the device for adjusting the position of the magnetic blocks to be tested, the side adjustment mechanism 11 includes driven rollers 13 located on either side of the transmission channel, and the top adjustment mechanism 12 includes multiple driven rollers 14 located at the top of the transmission channel, along with tensioning devices that drive these rollers toward or away from the transmission channel, and rotational devices that drive these rollers. The top and sides of the transmission channel are hollowed out to allow the multiple driven rollers on both sides and the top of the transmission channel to contact the magnetic blocks laterally and vertically, respectively. Driven rollers 13 and 14 are polyurethane rubber friction rollers, providing friction to drive the batch of magnetic blocks toward the end of the transmission channel. The distance from the lowest point of the driven roller 12 located at the top of the transmission channel to the transmission channel floor is slightly less than the height of the magnetic blocks. The driven rollers 13 on either side of the transmission channel are arranged in pairs, with the gap between the two rollers slightly less than the width of the magnetic blocks to be transported, and they rotate in opposite directions. This ensures that the multiple magnetic blocks that pass through the pair of driven rollers in the transmission channel are aligned front-to-back and left-to-right, resulting in a tighter engagement and less likely to misalign.

[0022] like Figure 3 As shown, the middle section of the magnetic block batch inspection equipment is provided with a material unloading and compacting conveying device 3. The material unloading and compacting conveying device 3 is provided with a pair of roller devices on both sides of the magnetic block transmission channel. The gap between the two rollers in the pair of roller devices is slightly smaller than the width of the magnetic block to be transmitted. When the batch of magnetic blocks moves along the transmission channel to the material unloading and compacting conveying device 3, the magnetic blocks are slightly blocked when they reach the roller device, thereby maintaining strong magnetic adsorption and making the connection between adjacent magnetic blocks more compact. If there are unqualified magnetic blocks, then when the unqualified magnetic blocks reach the magnetic block rejection device, they are rejected from the magnetic block queue. The other magnetic blocks are attracted by the magnetic force and will not fall apart, thereby maintaining the continuous attraction state of the remaining magnetic blocks and making them less likely to be misplaced.

[0023] The above is only an embodiment of the invention and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention and still fall within the scope of patent protection.
