Description

Technical Field

[0001] The present invention relates to the technical field of ferrite tile magnetism detection, and in particular to a ferrite tile magnetism automatic detection system. Background Art

[0002] The main production process of permanent ferrite magnetic tiles is: ball milling - molding - sintering - grinding - cleaning - sorting. In the tile molding and sintering process, if the molding pressing or sintering is not done properly, it is easy to have the problem of hidden cracks inside the tile. In the tile grinding process, improper grinding is easy to cause product size deviation, resulting in a decrease in the qualified rate of the tile. Therefore, hidden cracks and dimensions need to be further tested to ensure product quality.

[0003] The existing inspection plan is: However, since hidden cracks cannot be visually viewed, specially designed tooling is required to conduct obvious hidden crack and pressure resistance inspections. The tile magnetic products are hit with a cylinder hammer, and products that are not damaged after hammering are qualified products. After the initial inspection is qualified, workers will manually knock or drop them onto special metal blocks for testing. Products with hidden cracks will have different sounds, and those with crisp sounds are qualified products. The size also needs to be manually inspected piece by piece through fixed inspection gauge tooling, and manual sorting is used. Pieces are manually passed through the gauge. If they fail to pass, they are defective products, and the products are pulled out of the gauge and put into the defective product box.

[0004] The existing technology has the following deficiencies:

[0005] 1. When using a cylinder to knock on a tile magnetic product, there are many missed and wrong judgments, and the force cannot be accurately controlled, and it will change due to the change of compressed air provided by the air compressor. There is no mechanism to kick out defective products. Once the product is broken, the equipment will be stuck and need to be cleaned manually.

[0006] 2. Size inspection requires manual inspection of each piece through the gauge, which is very inefficient, and unqualified products are easily stuck in the gauge, further affecting efficiency.

[0007] 3. The hidden cracks inside the tile magnets cannot be seen with the naked eye, and workers judge whether they are qualified by the sound, which is very inefficient.

[0008] Existing technologies such as patent number: CN202022279582.5, a multifunctional magnetic tile overall performance testing tool, which uses this technology to test the overall performance of magnetic tile products without damaging the magnetic tile products; when testing the performance of multiple magnetic tiles, you only need to insert the magnetic tiles into the tooling for testing; the gap between the magnetic tiles in the tooling can be adjusted, and the magnetic properties of the magnetic tiles under different air gaps can be tested, and the magnetic properties of different sizes can be tested; it can be used to detect the inner and outer arcs, thickness, arch height, verticality of the arc, flatness and other shape and position dimensions of magnetic tile products. Manual operation is also required. The above manual detection is inefficient, and is easily affected by work experience and status, so the judgment of the product is easily affected, resulting in low accuracy, and is not suitable for enterprise-based production detection.

[0009] However, automatic production has the following problems:

[0010] 1. Due to the irregular shape of tile magnetic products, how to realize automatic arrangement and transportation of products;

[0011] 2. How to realize automatic passing of magnetic gauges, detect product size, and automatically kick out products stuck in the gauge and unqualified products;

[0012] 3. How to conduct preliminary inspection of obvious dark cracks in tile magnetic products and remove unqualified products;

[0013] 4. How to detect small internal cracks and eliminate unqualified products.

[0014] In summary, the present invention provides a ferrite tile magnetism automatic detection system. Summary of the invention

[0015] The purpose of the invention is to provide a ferrite tile magnet automatic detection system, which solves the problem of how to automatically detect the size and hidden crack defects of ferrite tile magnets.

[0016] The present invention is implemented as follows: a ferrite tile magnetism automatic detection system, the automatic detection system includes a controller and a guide mechanism, a size detection mechanism, a compression detection mechanism and a hidden crack detection mechanism that are communicatively connected to the controller;

[0017] The guide mechanism includes a first conveying structure and a stacking structure disposed below the output end of the first conveying structure, and the guide mechanism is used for automatically arranging the tile magnets and conveying them to the size detection mechanism;

[0018] The size detection mechanism includes a material pushing structure, a through gauge and a first power structure, wherein the material pushing structure cooperates with the bottom of the stacking structure to push the magnet to the through gauge, and the first power structure is used to push defective products in the through gauge out of the through gauge;

[0019] The pressure resistance detection mechanism is connected to the output end of the size detection mechanism, and the pressure resistance detection mechanism includes a servo motor placed above the pressure resistance detection station and a first pressure sensor placed at the output end of the servo motor;

[0020] The hidden crack detection mechanism includes a second conveying structure docked with the output end of the pressure resistance detection mechanism, a flip clamping assembly placed above the second conveying structure, and a hidden crack identification assembly cooperating with the output end of the second conveying structure.

[0021] Each mechanism in the present invention is connected to the controller for communication. The controller is a control system disclosed in the prior art and is used to control the operation of each mechanism in the present invention. Through the cooperation between the stacking structure of the guide mechanism and the first conveying structure, the tile magnets fall into the stacking structure along the first conveying structure for automatic arrangement, which is beneficial for the pushing structure to push the single piece into the through gauge for size detection. Qualified products continue to move forward to the pressure resistance detection mechanism, while unqualified products will be stuck and stay in the through gauge. At this time, the unqualified products are pushed out by the first power structure. The qualified products transported to the pressure resistance detection mechanism are sent to the servo motor for size detection. Drive the first pressure sensor to detect qualified products with different sizes, perform pressure detection on qualified products with different sizes at a set height, and obtain pressure data. If the data is within the set range, the products are qualified and enter the hidden crack detection structure. The qualified products of the tile magnetic compression resistance detection that enter the hidden crack detection structure are flipped over by the flipping clamping assembly, and fall on the hidden crack identification assembly. After collecting the sound, the sound is recognized by the software in the controller to determine whether the product is qualified. The qualified products are output from the hidden crack detection mechanism to the next program under the action of the next qualified product, thereby completing the automatic detection of the tile magnetic products and the three detections in the present invention are highly accurate.

[0022] A further technical solution of the present invention is: the stacking structure includes a stacking groove with openings at the upper and lower ends, and a first photoelectric sensor and a second photoelectric sensor are provided on the stacking groove, the first photoelectric sensor is placed at the set highest position of the tile magnetic stacking, and the second photoelectric sensor is placed at the set lowest position of the tile magnetic stacking, and the first photoelectric sensor and the second photoelectric sensor are both electrically connected to the controller.

[0023] A further technical solution of the present invention is: the width of the stacking groove can be adjusted according to the size of the tile magnet, and the tile magnets fall into the stacking groove in sequence. When the first photoelectric sensor senses that the tile magnet has reached the set highest position, the signal is transmitted to the controller, and the controller controls the first conveying structure to stop conveying. When the second photoelectric sensor senses that the tile magnet has reached the set lowest position, the controller controls the first conveying structure to increase the conveying speed to prevent the tile magnets that fall into the stacking groove from being broken.

[0024] A further technical solution of the present invention is: the pushing structure includes a pushing cylinder, a pushing head located at the output end of the pushing cylinder and cooperating with the magnet, a cylinder magnetic sensor for judging whether the pushing cylinder is completely pushed out, and a second pressure sensor located at the connection between the pushing head and the pushing cylinder.

[0025] The size of the tile magnet meets the requirements and can pass the gauge smoothly. At this time, the pushing cylinder can be fully extended. At the same time, the pressure value detected by the second pressure sensor is within the set range, indicating that the product is qualified and enters the next procedure; if the product is unqualified, the tile magnet cannot pass the gauge. At this time, the pushing cylinder cannot be fully extended. At the same time, the pressure value detected by the second pressure sensor is not within the set range, and it is pushed out through the first power structure.

[0026] A further technical solution of the present invention is that the through gauge is detachable and replaceable. Different products have different corresponding size requirements, and the through gauge in the present invention can be replaced with different through gauges according to different products.

[0027] A further technical solution of the present invention is: the first power structure includes a first lifting cylinder and a first horizontal cylinder connected to the output end of the first lifting cylinder, and the output end of the first horizontal cylinder passes through the through gauge to push defective products in the through gauge.

[0028] A further technical solution of the present invention is: the size detection mechanism also includes a first product automatic recovery structure, the first product automatic recovery structure includes a connecting plate, a sliding plate that can be opened and closed on the connecting plate, a first kicking cylinder that drives the sliding plate to move along the bottom of the connecting plate, and a first recovery box connected by a material guide plate is provided under the sliding plate.

[0029] A further technical solution of the present invention is: the pressure resistance detection mechanism includes a second product recovery structure, the second product recovery structure includes a second connecting plate docked with the output end of the size detection mechanism, a second openable and closable slide plate opened on the second connecting plate, and a second kicking cylinder that drives the second slide plate to move along the bottom of the second connecting plate, and a second recovery box connected by a second material guide plate is provided under the second slide plate.

[0030] The pushing structure is designed to replace manual plugging and unplugging to ensure that the magnet enters the gauge. The pressure sensor and magnetic sensor cooperate with the cylinder to push the magnet forward. When the pressure is abnormal, the cylinder will stop moving immediately to prevent the magnet product from being completely stuck inside the gauge. Unqualified products stuck in the gauge can be pushed out by the first power structure and fall into the first product automatic recovery structure.

[0031] The first horizontal cylinder can push the unqualified products in the through gauge back to the top of the second product automatic recovery structure, and the unqualified products can be recovered by opening the second product automatic recovery structure.

[0032] A further technical solution of the present invention is: the structure of the first product recovery structure is the same as that of the second product recovery structure. When the controller detects that the corresponding position is a defective product, the controller controls the movement of the first kicking cylinder and the second kicking cylinder, thereby driving the movement of the first slide plate and the second slide plate, so that the drop port of the defective product opens, and the defective product enters the corresponding recycling box along the drop port.

[0033] The pressure resistance detection mechanism, using the cooperation of pressure sensor and servo motor, can accurately control the downward pressure distance and real-time pressure feedback, and accurately judge the pressure resistance of the product.

[0034] A further technical solution of the present invention is: the flipping and clamping assembly includes a flipping cylinder, a second lifting cylinder and a translation cylinder connected to the second lifting cylinder for driving the second lifting cylinder to move horizontally, which are arranged in sequence along the conveying direction of the second conveying structure; the output end of the flipping cylinder is provided with a hook for hooking up the tile magnet; the output end of the second lifting cylinder is provided with a clamping member for clamping the tile magnet.

[0035] Since the tile magnet product has an arch height, one end of the tile magnet can be hung by the hook of the flipping cylinder. Under the movement of the second transmission structure, the flipping cylinder is lifted up at the same time, and the tile magnet completes a 180-degree flip. The second lifting cylinder moves and the clamping part clamps the tile magnet. The translation cylinder drives the second lifting cylinder to move to the hidden crack identification component. The cylinder in the clamping part controls the clamping part to release the tile magnet, and the tile magnet falls onto the metal block used to detect hidden cracks.

[0036] A further technical solution of the present invention is: the hidden crack recognition component includes a metal block and a sound recognition module placed on the metal block, and the sound recognition module is electrically connected to the controller.

[0037] The product falling onto the metal block will make a sound, which will be collected by the sound recognition module and the attenuation of the sound will be identified by the software in the controller to determine whether there are hidden cracks inside the magnet. If there are no hidden cracks, the next process will be entered.

[0038] The tile magnetic hidden crack detection mechanism is an ingeniously designed product flipping mechanism. It uses the tile magnetic falling sound instead of the knocking sound. The falling sound can more comprehensively judge the hidden cracks inside the product. At the same time, it uses a fixed frequency sound recognition module to collect sounds, identify the sound attenuation through software, and judge whether there are hidden cracks inside.

[0039] A further technical solution of the present invention is: the hidden crack detection mechanism also includes a third product recovery structure, the third product recovery structure includes a third kicking cylinder, a third material guide piece placed on one side of the hidden crack identification component, and a third recovery box coordinated with the output end of the third material guide piece, the third kicking cylinder is placed on the side of the hidden crack identification component away from the third material guide piece.

[0040] The third kicking cylinder and the third material guide are respectively placed at the two ends of the metal block, and the third kicking cylinder and the third material guide cooperate with each other to kick out defective products on the metal block to the third recycling box.

[0041] Products that fall onto the metal block will make sounds, which will be collected through the sound recognition module. The software in the controller will identify the attenuation of the sound to determine whether there are hidden cracks inside the magnetic tile. If there are no hidden cracks, it will enter the next process. Products with hidden cracks will be recycled through the third product recycling structure.

[0042] A further technical solution of the present invention is: the automatic detection system also includes a magnetic automatic packing mechanism, which includes a third conveying structure that cooperates with the output end of the second conveying structure, a driving assembly placed above the third conveying structure, and a turnover box that cooperates with the output end of the third conveying structure.

[0043] The Wa-Magnetic automatic packing mechanism is used to automatically pack products that have passed size inspection, hidden crack pressure inspection and small hidden crack inspection.

[0044] A further technical solution of the present invention is: the driving assembly includes a third lifting cylinder, a clamping assembly placed at the output end of the third lifting cylinder, a horizontal cylinder driving the third lifting cylinder to move horizontally on the horizontal plane, and a vertical cylinder driving the third lifting cylinder to move vertically on the horizontal plane, and the clamping assembly is used to clamp a group of magnets placed on the third conveying structure.

[0045] During the packing process, since the transfer box does not move, the qualified products can move up and down, front and back, and left and right through the cooperation of the driving components, so that the qualified products can be neatly arranged in the transfer box.

[0046] Beneficial effects of the present invention: each mechanism in the present invention is connected to the controller for communication. The controller is a control system disclosed in the prior art and is used to control the operation of each mechanism in the present invention. The guide mechanism allows the tile magnet to fall into the stacking structure along the first conveying structure for automatic arrangement, which is beneficial for pushing the single piece of the pushing structure into the through gauge for size detection. Unqualified products will not be stuck in the through gauge. At this time, the first power structure is used to push the unqualified products out of the through gauge to avoid affecting the subsequent product detection. In a further solution, the first power structure pushes the unqualified products back to the first product automatic recovery structure. The first product automatic recovery structure can be opened and closed, so that the unqualified products fall into the recovery area. The defective products can be automatically kicked out during the detection.

[0047] The qualified products transported to the compression testing mechanism are tested by the first pressure sensor driven by the servo motor. The qualified products are tested at a set height to obtain pressure data. If they are within the set range, they are qualified and enter the hidden crack detection structure. The unqualified products are recovered by opening the second product automatic recovery structure. The hidden crack compression test is accurate and fast, and the pressure applied is uniform and accurate, which can automatically remove defective products.

[0048] The qualified products of the tile magnetic compression test that enter the hidden crack detection structure are flipped over by the flip clamping component and fall on the hidden crack identification component. After collecting the sound, the sound is recognized by the software in the controller to determine whether the product is qualified. The unqualified products are automatically recycled by the third product recycling structure. The qualified products are output from the hidden crack detection mechanism to the next program under the action of the next qualified product. The internal dark cracks are collected by the fixed frequency sound recognition module, and the sound of the tile magnetic falling is recognized by the software to determine whether there are dark cracks inside, so as to improve the accuracy of product detection as much as possible.

[0049] The present invention realizes the automatic detection of size, hidden crack compression resistance and small hidden cracks, has high efficiency and low labor cost, and can be applied to tile magnetic products of various specifications, and only needs to replace the through gauge and the push head.

[0059] Embodiment 1:

[0060] Figure 1-6A ferrite tile magnetism automatic detection system is shown, the automatic detection system comprises a controller and a guide mechanism 1, a size detection mechanism 2, a compression detection mechanism 3 and a hidden crack detection mechanism 4 which are communicatively connected with the controller;

[0061] The guide mechanism 1 includes a first conveying structure 11 and a stacking structure 12 disposed below the output end of the first conveying structure 11. The guide mechanism 1 is used to automatically arrange the magnetic tiles and convey them to the size detection mechanism 2.

[0062] The size detection mechanism 2 includes a pusher structure 21, a through gauge 22 and a first power structure 23. The pusher structure 21 cooperates with the bottom of the stacking structure 12 to push the magnet to the through gauge 22. The first power structure 23 is used to push defective products in the through gauge 22 out of the through gauge.

[0063] The pressure-resistant detection mechanism 3 is connected to the output end of the size detection mechanism 2, and the pressure-resistant detection mechanism 3 includes a servo motor 32 placed above the pressure-resistant detection station and a first pressure sensor 33 placed at the output end of the servo motor 32;

[0064] The hidden crack detection mechanism 4 includes a second conveying structure 41 docked with the output end of the pressure resistance detection mechanism 3, a flip clamping assembly 42 placed above the second conveying structure 41, and a hidden crack identification assembly 43 coordinated with the output end of the second conveying structure 41.

[0065] In this embodiment, the stacking structure 12 includes a stacking groove with openings at the upper and lower ends, and a first photoelectric sensor 13 and a second photoelectric sensor 14 are provided on the stacking groove. The first photoelectric sensor 13 is placed at the set highest position of the tile magnet stacking, and the second photoelectric sensor 14 is placed at the set lowest position of the tile magnet stacking. The first photoelectric sensor 13 and the second photoelectric sensor 14 are both electrically connected to the controller.

[0066] As a preferred embodiment, the width of the stacking groove can be adjusted according to the size of the tile magnet, and the tile magnets fall into the stacking groove in sequence. When the first photoelectric sensor senses that the tile magnet has reached the set highest position, the signal is transmitted to the controller, and the controller controls the first conveying structure to stop conveying. When the second photoelectric sensor senses that the tile magnet has reached the set lowest position, the controller controls the first conveying structure to increase the conveying speed to prevent the tile magnets from falling into the stacking groove and breaking.

[0067] In this embodiment, the pushing structure 21 includes a pushing cylinder 211, a pushing head 212 located at the output end of the pushing cylinder 211 and cooperating with a magnet, a cylinder magnetic sensor 213 for determining whether the pushing cylinder 211 is completely pushed out, and a second pressure sensor 214 located at the connection between the pushing head 212 and the pushing cylinder 211.

[0068] The size of the tile magnet meets the requirements and can pass the gauge smoothly. At this time, the pushing cylinder can be fully extended. At the same time, the pressure value detected by the second pressure sensor is within the set range, indicating that the product is qualified and enters the next procedure; if the product is unqualified, the tile magnet cannot pass the gauge. At this time, the pushing cylinder cannot be fully extended. At the same time, the pressure value detected by the second pressure sensor is not within the set range, and it is pushed out through the first power structure.

[0069] As a preferred embodiment, the through gauge 22 is detachable and replaceable. Different products have different size requirements, and the through gauge in the present invention can be replaced with different through gauges according to different products.

[0071] In this embodiment, the size detection mechanism also includes a first product automatic recovery structure, and the first product automatic recovery structure 24 includes a connecting plate, a slide plate 241 that can be opened and closed on the connecting plate, and a first kicking cylinder 242 that drives the slide plate 241 to move along the bottom of the connecting plate. A first recovery box connected by a guide plate 243 is provided under the slide plate 241.

[0072] In this embodiment, the pressure resistance detection mechanism includes a second product recovery structure, and the second product recovery structure 31 includes a second connecting plate docked with the output end of the size detection mechanism 2, a second openable and closable slide plate 311 opened on the second connecting plate, and a second kicking cylinder 312 that drives the second slide plate 311 to move along the bottom of the second connecting plate. A second recovery box connected by a second guide plate 313 is provided under the second slide plate 311.

[0073] The pushing structure is designed to replace manual plugging and unplugging to ensure that the magnet enters the gauge. The pressure sensor and magnetic sensor cooperate with the cylinder to push the magnet forward. When the pressure is abnormal, the cylinder will stop moving immediately to prevent the magnet product from being completely stuck inside the gauge. Unqualified products stuck in the gauge can be pushed out by the first power structure and fall into the first product automatic recovery structure.

[0074] The first horizontal cylinder can push the defective products in the through gauge back to the top of the second product automatic recovery structure, and the defective products can be recovered by opening the second product automatic recovery structure.

[0075] In this embodiment, the structure of the first product recovery structure is the same as that of the second product recovery structure. When the controller detects that the corresponding position is a defective product, the controller controls the movement of the first kicking cylinder and the second kicking cylinder, thereby driving the movement of the first slide plate and the second slide plate, so that the defective product drop port opens, and the defective product enters the corresponding recycling box along the drop port.

[0076] The pressure resistance detection mechanism, using the cooperation of pressure sensor and servo motor, can accurately control the downward pressure distance and real-time pressure feedback, and accurately judge the pressure resistance of the product.

[0077] In this embodiment, the flipping and clamping assembly 42 includes a flipping cylinder 421, a second lifting cylinder 422, and a translation cylinder 423 connected to the second lifting cylinder 422 for driving the second lifting cylinder 422 to move horizontally, which are arranged in sequence along the conveying direction of the second conveying structure 41. The output end of the flipping cylinder 421 is provided with a hook for hooking up the tile magnet, and the output end of the second lifting cylinder 422 is provided with a clamping piece for clamping the tile magnet.

[0078] Since the tile magnet product has an arch height, one end of the tile magnet can be hung by the hook of the flipping cylinder. Under the movement of the second transmission structure, the flipping cylinder is lifted up at the same time, and the tile magnet completes a 180-degree flip. The second lifting cylinder moves and the clamping part clamps the tile magnet. The translation cylinder drives the second lifting cylinder to move to the hidden crack identification component. The cylinder in the clamping part controls the clamping part to release the tile magnet, and the tile magnet falls onto the metal block used to detect hidden cracks.

[0079] In this embodiment, the hidden crack recognition component 43 includes a metal block 431 and a sound recognition module 432 disposed on the metal block 431 , and the sound recognition module 432 is electrically connected to the controller.

[0080] The product falling onto the metal block will make a sound, which will be collected by the sound recognition module and the attenuation of the sound will be identified by the software in the controller to determine whether there are hidden cracks inside the magnet. If there are no hidden cracks, the next process will be entered.

[0081] The tile magnetic hidden crack detection mechanism is an ingeniously designed product flipping mechanism. It uses the tile magnetic falling sound instead of the knocking sound. The falling sound can more comprehensively judge the hidden cracks inside the product. At the same time, it uses a fixed frequency sound recognition module to collect sounds, identify the sound attenuation through software, and judge whether there are hidden cracks inside.

[0082] In this embodiment, the hidden crack detection mechanism also includes a third product recovery structure, and the third product recovery structure 44 includes a third kicking cylinder 441, a third material guide member 442 placed on one side of the hidden crack identification component 43, and a third recovery box coordinated with the output end of the third material guide member 442, and the third kicking cylinder 441 is placed on the side of the hidden crack identification component 43 away from the third material guide member 442.

[0083] The third kicking cylinder and the third material guide are respectively placed at the two ends of the metal block, and the third kicking cylinder and the third material guide cooperate with each other to kick out defective products on the metal block to the third recycling box.

[0084] Products that fall onto the metal block will make sounds, which will be collected through the sound recognition module. The software in the controller will identify the attenuation of the sound to determine whether there are hidden cracks inside the magnetic tile. If there are no hidden cracks, it will enter the next process. Products with hidden cracks will be recycled through the third product recycling structure.

[0085] In this embodiment, the automatic detection system also includes a magnetic automatic packing mechanism 5, which includes a third conveying structure 51 that cooperates with the output end of the second conveying structure 41, a driving assembly placed above the third conveying structure 51, and a turnover box that cooperates with the output end of the third conveying structure 51.

[0086] The Wa-Magnetic automatic packing mechanism is used to automatically pack products that have passed size inspection, hidden crack pressure inspection and small hidden crack inspection.

[0087] In this embodiment, the driving assembly includes a third lifting cylinder 52, a clamping assembly 53 placed at the output end of the third lifting cylinder 52, a horizontal cylinder 54 that drives the third lifting cylinder 52 to move horizontally on the horizontal plane, and a vertical cylinder 55 that drives the third lifting cylinder 52 to move vertically on the horizontal plane. The clamping assembly 53 is used to clamp a group of magnets placed on the third conveying structure 51.

[0088] During the packing process, since the transfer box does not move, the qualified products can move up and down, front and back, and left and right through the cooperation of the driving components, so that the qualified products can be neatly arranged in the transfer box.

[0089] In this embodiment, the Wa magnetic automatic packing mechanism 5 also includes a third photoelectric sensor 56, and a blocking plate is provided at the output end of the third conveying structure. When the products accumulate to a set quantity, the third photoelectric sensor 56 transmits a signal to the controller to control the driving component to transfer the products to the transfer box.

[0090] In this embodiment, the first power structure 23 is used to push the defective products in the through gauge 22 to the top of the first product automatic recovery structure 24, and the first product automatic recovery structure 24 can be opened and closed to recover the defective products pushed above it.

[0091] In this embodiment, the second defective product recovery structure is placed at the compression resistance testing station and can be opened and closed to recover defective products.

[0092] Working principle of the present invention: each mechanism in the present invention is communicatively connected with the controller, and the controller is a control system disclosed in the prior art, which is used to control the operation of each mechanism in the present invention; through the cooperation between the stacking structure of the guide mechanism and the first conveying structure, the tile magnets fall into the stacking structure along the first conveying structure for automatic arrangement, which is beneficial to the pushing structure single piece to be pushed into the through gauge for size detection, and the qualified products continue to move forward to the pressure resistance detection mechanism, and the unqualified products will be stuck and stay in the through gauge. At this time, the unqualified products are pushed back to the first product automatic recovery structure through the first power structure, and the first product automatic recovery structure can be opened and closed, so that the unqualified products fall into the recovery area; the qualified products transported to the pressure resistance detection mechanism are detected by the first pressure sensor driven by the servo motor, and the qualified products are pressure-tested at a set height to obtain pressure data. If it is within the set range, it is qualified and enters the dark cracking process. The detection structure is used to recover unqualified products through the opening of the second product automatic recovery structure; qualified products entering the tile magnetic compression test of the dark crack detection structure are flipped over by the flipping clamping component and fall on the dark crack identification component. After collecting the sound, the sound is recognized by the software in the controller to determine whether the product is qualified. Unqualified products are automatically recovered by the third product recovery structure, and qualified products are output from the dark crack detection mechanism to the next program under the action of the next qualified product, thereby realizing automatic detection of size, dark crack compression and small dark cracks, with high efficiency and low labor cost, and can be applied to tile magnetic products of various specifications, only the through gauge and push head need to be replaced; defective products can be automatically kicked out during detection, dark crack compression detection is accurate and fast, and the pressure applied is uniform and accurate. The internal dark cracks are detected through a fixed frequency sound recognition module, which collects the sound of the tile magnetic falling, and the sound attenuation is recognized by the software to determine whether there are dark cracks inside, so as to improve the product detection accuracy as much as possible.
