Description

Technical Field

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

[0002] Ferrite magnetic tiles or rare earth magnetic tiles are characterized by their shape being part of a rounded arc, including an outer arc surface, an inner arc surface, a large end face, a small end face, chamfers, and other outer surfaces. Ferrite magnetic tiles are characterized by their deep black color (the color may vary slightly depending on the process), while rare earth magnetic tiles exhibit various different glossy colors.

[0003] A magnetic tile inspection device and method (patent number CN201910375791.9) discloses a magnetic tile inspection device, including a conveying mechanism, an inspection mechanism, and a sorting mechanism. The conveying mechanism includes six conveying stations connected sequentially from high to low. Each conveying station includes a conveyor belt and guard plates disposed on both sides of the conveyor belt. The inspection mechanism includes a first inspection unit and a second inspection unit. The first inspection unit is provided above the first and sixth conveying stations, and the second inspection unit is provided above the remaining four output stations. Each output station is equipped with a sorting mechanism. This magnetic tile inspection device uses six conveying stations and more than eight visual inspection cameras to inspect all surfaces of the magnetic tiles, completely eliminating manual re-inspection and improving the inspection efficiency of the magnetic tile appearance. The sequentially decreasing height of the six conveying stations allows the moving magnetic tiles to flip over using gravitational potential energy and inertia, which has the advantages of high efficiency, low cost, and stable reliability.

[0004] However, the magnetic tile detection device requires the magnetic tile to be flipped five times during the detection process. During each flip, there is a probability that the magnetic tile will get stuck. At this time, the magnetic tile detection device must be paused to deal with the stuck magnetic tile before the detection can continue, which has the technical problem of low detection efficiency.

A good product unloading workbench 4 is connected to the other end of the feeding track 3. The frame platform 1 is provided with a first appearance inspection mechanism 5, a first rejection mechanism 6, a flipping mechanism 7, a second appearance inspection mechanism 8, and a second rejection mechanism 9 in sequence along the conveying direction of the feeding track 3 between the vibrating plate 2 and the good product unloading workbench 4. A defective product storage box 10 is provided on one side of the first rejection mechanism 6 and the second rejection mechanism 9.

[0030] In this embodiment, the magnetic tile is fed onto the feeding track 3 via the vibrating disc 2. When the magnetic tile is transported to the area below the first appearance inspection mechanism 5, the front of the magnetic tile is inspected by the first appearance inspection mechanism 5. If a defective product is detected, the magnetic tile is transferred to the defective product storage box 10 at one end of the first rejection mechanism 6 via the first rejection mechanism 6. Good magnetic tiles continue to be transported to the flipping mechanism 7 via the feeding track 3. The flipping mechanism 7 flips the magnetic tile. The flipped magnetic tile continues to be transported to the area below the second appearance inspection mechanism 8 for appearance inspection of the back of the magnetic tile. Defective products are transferred to the corresponding defective product storage box 10 via the second rejection mechanism 9. Qualified magnetic tiles are transferred to the good product unloading workbench 4. The magnetic tile is transported to the end via the feeding track 3 in one go, without the need for multiple transfers and flips, thereby achieving efficient inspection and improving inspection efficiency.

[0031] Preferably, such as Figure 2As shown, the first appearance inspection mechanism 5 and the second appearance inspection mechanism 8 have the same structure, both including a support frame 51, at least four first inspection cameras 52 and at least one second inspection camera 53. The support frame 51 is straddling the feeding track 3 and is bolted to the bottom of the frame platform 1. The four first inspection cameras 52 are respectively fixed on the four sides of the support frame 51, front, back, left, and right, and are all fixed to the support frame 51 by adjusting plates 76. The adjusting plates 76 are provided with arc-shaped adjusting grooves 761. A mounting block is fixedly connected to one side of the first inspection camera 52. The mounting block is provided with a through hole, and bolts are inserted into the through hole and the adjusting groove. The adjustment plate 76 is fixedly connected to the support frame 51, and the detection ends of the four first detection cameras 52 are all facing the same area on the feeding track 3 to perform appearance inspection on the front, back, left and right sides of the magnetic tile in this area. In addition, the second detection camera 53 is fixedly installed on the upper end of the support frame 51 with the detection end of the second detection camera 53 vertically downward facing the end face of the feeding track 3 to inspect the upper end of the magnetic tile. The four first detection cameras 52 and one second detection camera 53 realize the all-round inspection of the magnetic tile (except the bottom). Each detection end of the first detection camera 52 is fixed with a three-color light source.

[0032] Optionally, the structures of the first appearance inspection mechanism 5 and the second appearance inspection mechanism 8 may also be different. The number of the first inspection cameras 52 may be different, or the number of the second inspection cameras 53 may be different, or the inspection angle may be different. No restrictions are imposed here.

[0033] Preferably, such as Figure 3 As shown, the first rejection mechanism 6 and the second rejection mechanism 9 have the same structure, both including a fixed frame 61, two support plates 62, two transmission wheels, and a transmission belt 63. The fixed frame 61 is fixedly installed on the frame platform 1. The two support plates 62 are fixedly installed on the upper end of the fixed frame 61 and are arranged parallel to each other. The two support plates 62 are located above the feeding track 3 and are perpendicular to the conveying direction of the feeding track 3. The two ends of the two support plates 62 are respectively rotatably connected to the two transmission wheels. That is, a connecting plate is fixed at both ends of each support plate 62 and fixed by bolts. Each connecting part is provided with a rotating groove, and the transmission wheel is embedded in the rotating groove. The transmission belt 63 is mounted on two transmission wheels and is rotatably connected. A drive motor is fixedly connected to one side of one of the transmission wheels. The drive motor can be fixedly connected to the fixed frame 61 or to the support plate 62. The motor drives the transmission wheel to rotate, which in turn drives the transmission belt 63 to rotate. Several push blocks 64 are evenly arranged on the outer periphery of the transmission belt 63. The push blocks 64 push the items judged as NG on the feeding track 3 to be lifted out of the feeding track 3. The defective product collection box 10 is located below one end of the transmission belt. The collection box is set below the conveying plane of the feeding track 3 and is generally used to collect the rejected defective products.

[0034] Optionally, the first rejection mechanism 6 includes a transverse drive rail, a telescopic cylinder, and a cylinder gripper. The transverse drive rail spans above the feeding track 3 and is slidably connected to a slider. The telescopic cylinder is fixedly connected to the slider, and the output end of the telescopic cylinder is vertically downward. The output end of the telescopic cylinder is fixedly connected to the cylinder gripper. The cylinder gripper picks up the magnetic tile and transfers it to the defective product storage box 10.

[0035] Optionally, the transverse drive rail can be a linear guide rail or a combination of a lead screw and a motor; the telescopic cylinder can also be replaced with a lead screw and motor drive structure; the cylinder gripper can be replaced with a suction nozzle to transfer the magnetic tile.

[0036] In one feasible embodiment, the first rejection mechanism includes a telescopic cylinder and a pusher plate. The telescopic cylinder is fixedly mounted on one side of the linear track, with its drive end facing the feeding track. The output end of the telescopic cylinder is fixedly connected to the pusher plate, and the pusher plate is driven by the telescopic cylinder to push the magnetic tile out of the feeding track.

[0037] Optionally, the structures of the first rejection mechanism 6 and the second rejection mechanism 9 are different, and both the first rejection mechanism and the second rejection mechanism can be one of the above schemes.

[0038] Preferably, one end of one of the support plates 62 is provided with a photoelectric switch 65, and each pusher block 64 is provided with a baffle 66 on one side of the photoelectric switch 65. The number of pusher blocks 64 that have passed is recorded by the power supply switch so as to determine that the target magnetic tile has been removed and to stop the rotating transmission belt in time.

[0039] Preferably, such as Figure 6 As shown, a defective product transport mechanism 11 is provided on the other side of the feeding track 3 away from the defective product storage box along the conveying direction. A receiving box 12 is provided at the end of the conveying direction of the defective product transport mechanism 11. A square frame is provided below the first rejection mechanism 6 and the second rejection mechanism 9 to prevent the magnetic tiles from flying out. The bottom of the square frame is fixedly connected to one side of the defective product transport mechanism 11 and the bottom is directly above the defective product transport mechanism 11. By rotating the first rejection mechanism 6 and the second rejection mechanism 9 in opposite directions, the magnetic tiles are sorted and rejected, and are rejected onto the defective product transport mechanism 11 and transported to the storage box.

[0040] Preferably, such as Figures 4 to 5As shown, the flipping mechanism 7 includes a guide assembly and a flipping component located at one end of the guide assembly. The guide assembly includes two parallel guide plates 73, which are staggered from one another. The two guide plates 73 are obliquely cut on opposite sides near the end of the first rejection mechanism 6, forming a figure-eight shape to guide the magnetic tile to a preset position. The two guide plates 73 are adjustablely connected to both sides of the feeding track 3. The flipping component has a first guide bar 71 and a second guide bar 72 arranged opposite each other, parallel to each other. An arc-shaped guide portion 711 is provided on the end of the first guide bar 71 near the guide assembly. The arc surface of the arc-shaped guide portion 711 gradually decreases along the transport direction of the feeding track 3. The second guide bar 72 and the first guide bar 71 are arranged parallel to each other. A beveled section 721 is provided on the opposite side of the guide bar 71. The beveled section 721 is located at the end of the second guide bar 72 away from the guide assembly. The first guide bar 71 and the second guide bar 72 are respectively adjustablely connected to both sides of the feeding track 3. The first guide bar 71 and the second guide bar 72 are staggered, with the first guide bar 71 in front and the second guide bar 72 behind. After the magnetic tile is positioned by the guide assembly, it passes through the arc-shaped guide section 711 of the first guide bar 71. The magnetic tile is lifted by the arc-shaped guide section 711 and continues to move forward. As the arc surface component of the arc-shaped guide section 711 decreases, the rising angle of the magnetic tile becomes larger and larger. Finally, it is flipped over and falls through the beveled section 721 component of the second guide bar 72 until it falls smoothly onto the feeding track 3, thus achieving the flipping of the magnetic tile.

[0041] Preferably, such as Figure 5 As shown, the flipping assembly also includes two vertical plates 74, two horizontal plates 75, and two adjusting plates 76. The two vertical plates 74 are fixedly mounted on both sides of the feeding track 3. The two horizontal plates 75 are rotatably connected to the upper ends of the vertical plates 74. Each adjusting plate 76 is provided with multiple adjusting grooves 761. One end of each adjusting plate 76 is bolted to the horizontal plate 75. The bolt passes through the adjusting groove 761 and abuts against the adjusting plate 76. The other end of each adjusting plate 76 is connected to the first guide bar 71 and the second guide bar 72, respectively. The distance between the first guide bar 71 and the second guide bar 72 can be adjusted through the adjusting groove 761. An arc-shaped through groove is provided at one end of the horizontal plate 75, and a corresponding threaded hole is provided at the upper end of the vertical plate 74. The bolt is inserted into the through groove and threadedly connected to the threaded hole. The angle of the first guide bar 71 and the second guide bar 72 can be adjusted through the arc-shaped through groove.

[0042] Optionally, the connection relationship between the first guide plate 73 and the second guide plate 73 and the two sides of the feeding track 3 is similar to the connection relationship between the first guide bar 71 and the second guide bar 72. The position adjustment of the first guide plate 73 and the second guide plate 73 is achieved through the adjustment groove 761 and the arc-shaped through groove.

[0043] Preferably, the feeding track 3 is also arranged across the third rejection mechanism 14 between the first rejection mechanism 6 and the second appearance inspection mechanism 8. The third rejection mechanism 14 has the same structure as the first rejection mechanism 6 and the second rejection mechanism 9, and the third rejection mechanism 14 is used for classification and rejection.

[0044] Preferably, the feeding track 3 is provided with a plurality of encoders 13 in its conveying direction. The code disk of the encoder 13 is located directly above the feeding track 3 and abuts against the magnetic tile. When the magnetic tile passes the code disk of the encoder 13, it drives the code disk to rotate, thereby recording the position of the magnetic tile so as to accurately remove the corresponding defective magnetic tile.

[0045] The feeding track 3 and the defective product transport track can be one of the following: belt conveyor, steel belt conveyor, mesh belt conveyor, scraper conveyor, roller conveyor, roller conveyor, and vibrating conveyor. Specifically, its structure can include two support bars that span the frame platform 1. The two support bars are arranged in parallel, and rollers are rotatably connected to both ends of the support bars. A belt is fitted on the two rollers, and the belt is driven to rotate by a motor.

[0046] Optionally, the vibrating disc 2 can be set inside the frame platform 1 or outside the frame platform 1. The vibrating disc 2 is existing technology and will not be described in detail here.

[0047] The first detection camera 52 and the second detection camera 53 can be one of a charge-coupled device (CCD) camera, a CMOS camera, a black-and-white (monochrome) camera, or a color camera.

[0048] Specifically, the working principle and usage process of this utility model are as follows: The magnetic tile is fed to the feeding track 3 by the vibrating plate 2. When the magnetic tile is transported to the first appearance inspection mechanism 5, the front of the magnetic tile is inspected by the first appearance inspection mechanism 5. If a defective product is detected, the magnetic tile is transferred to the defective product storage box 10 at one end of the first rejection mechanism 6 by the first rejection mechanism 6. The good magnetic tile continues to be transported to the flipping mechanism 7 by the feeding track 3. The flipping mechanism 7 flips the magnetic tile. The flipped magnetic tile continues to be transported to the second appearance inspection mechanism 8 for appearance inspection of the back of the magnetic tile. Defective products are transferred to the corresponding defective product storage box 10 by the second rejection mechanism 9. The qualified magnetic tile is transferred to the good product unloading workbench 4. The magnetic tile is transported to the good product unloading workbench in one stop by the feeding track 3, without multiple transfers and flipping, thereby achieving efficient inspection and improving inspection efficiency.
