Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core processing, and more specifically, to a magnetic core aligning machine. Background Art

[0002] A magnetic core refers to a sintered magnetic metal oxide composed of various iron oxide mixtures. Before production and packaging, its appearance is inspected to confirm whether there are appearance defects such as burrs, chipping, cracking, and deformation.

[0003] The traditional method for inspecting the appearance of magnetic cores is mainly to continuously fork a special fork into the rotating basket of magnetic cores, pierce the magnetic cores onto the fork teeth, and arrange them in a row for inspection. This method has the following problems: 1. It is easy to damage the magnetic cores. Especially during the process of forking the magnetic cores, the fork tip is easy to scratch the plastic spraying layer on the surface of the magnetic cores, and even cause chipping and fracture of the magnetic cores. 2. The process of threading the magnetic cores is relatively long, and the operation efficiency is low. 3. The labor intensity is relatively high. Repeating the process of aligning the magnetic cores for a long period of time is likely to cause physical fatigue and even affect the subsequent appearance inspection. Therefore, it has become an urgent task to invent a device that can replace manual labor to complete the alignment of magnetic cores.

[0004] Currently, the use of an automatic feeding method for magnetic cores can improve production efficiency. Currently, the automatic feeding methods are mainly divided into two types: vibrating bowl feeding and conveyor belt feeding. Since the vibrating bowl feeding has relatively large vibration noise and the vibration force is easy to damage the magnetic cores, the conveyor belt feeding method is mostly selected. However, the conveyor belt feeding method also has the phenomenon of jamming in actual use.

[0005] Therefore, researching and developing a magnetic core aligning machine that is not prone to jamming is an urgent problem that needs to be solved by those skilled in the art. Content of the Utility Model

[0050] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0051] The utility model discloses a magnetic core arrangement machine, comprising:

[0052] Rack 1,

[0053] A material unloading conveyor belt 2, wherein the material unloading conveyor belt 2 is connected to the frame 1;

[0054] A feeding conveyor belt 3, which is connected to the frame 1 and is located at the end of the unloading conveyor belt 2;

[0055] The single-row feeding assembly 4 includes: a guide plate 41 and a baffle plate 42; the guide plate 41 and the baffle plate 42 are both connected to the frame 1 and are arranged above the feeding conveyor belt 3, the guide plate 41 and the baffle plate 42 are arranged in sequence along the moving direction of the magnetic core, and limit the single-layer and single-row feeding of the magnetic core;

[0056] Screening assembly 5, the screening assembly 5 is located behind the material blocking plate 42; the screening assembly 5 includes: a width limiting block 51, a pressing plate 52 and a sorting block 53; the width limiting block 51 and the sorting block 53 are both connected to the frame 1, the pressing plate 52 is placed on the top of the width limiting block 51, and the edge of the pressing plate 52 extends out of the width limiting block 51 and presses the plane end of the magnetic core;

[0057] The turning assembly 6 is arranged at the end of the screening assembly 5 and connected to the frame 1. The magnetic cores are turned over and arranged on the turning assembly 6 and stacked;

[0058] The tray 7 is connected to the frame 1 and is located at the end of the flip assembly 6 to receive the magnetic cores arranged on the flip assembly 6 .

[0059] In order to further optimize the above technical solution, the moving directions of the unloading conveyor belt 2 and the feeding conveyor belt 3 are perpendicular, and the conveying directions of the feeding conveyor belt 3 and the flip conveyor belt 61 are perpendicular.

[0060] In order to further optimize the above technical solution, a return conveyor belt 8 is arranged side by side on one side of the feed conveyor belt 3 close to the sorting block 53. The return conveyor belt 8 is arranged at an angle, with one end located below the sorting block 53 and the other end located above the feed conveyor belt 3. The conveying direction of the return conveyor belt 8 is opposite to that of the feed conveyor belt 3, and a return baffle 9 inclined toward the direction of the feed conveyor belt 3 is provided above the return conveyor belt 8.

[0061] To further optimize the above technical solution, the single-column feeding assembly 4 further includes: a material shortage baffle 43, a material shortage sensor 44, and a counterweight 45; the material shortage baffle 43 is hinged to the frame 1; the counterweight 45 is fixed to the surface of the material shortage baffle 43; the material shortage sensor 44 is connected to the frame 1 and detects the state of the material shortage baffle 43. The swinging of the material shortage baffle 43 can preliminarily limit two or more layers of the magnetic cores to be arranged in a single layer; the distance between the baffle plate 42 and the feeding conveyor belt 3 is greater than the height of a single layer of magnetic cores and less than the height of two layers of magnetic cores, which can further limit the number of layers of the magnetic cores and ensure that the magnetic cores passing through the baffle plate 42 are all arranged in a single layer.

[0062] To further optimize the above technical solution, when the material shortage baffle 43 is in a vertical state, the material shortage sensor 44 will sense the material shortage baffle 43. If the material shortage baffle 43 is sensed for a long time, it means that the feeding conveyor belt 3 is in a material shortage state. The bottom of the material shortage baffle 43 is bent along the moving direction of the magnetic cores.

[0063] To further optimize the above technical solution, the guide plate 41 is composed of multiple guide plates. From the end of the blanking conveyor belt 2 to when entering the screening assembly 5, an inclined guide plate, an arc-shaped guide plate, and an inclined guide plate are sequentially arranged. The purpose is to make the magnetic cores arranged in a single direction when entering the screening assembly 5 and avoid jamming.

[0064] To further optimize the above technical solution, the sorting block 53 is sequentially a guiding section 531, a screening section 532, and a returning section 533 along the moving direction of the magnetic cores; on one side of the top of the guiding section 531 away from the feeding conveyor belt 3, there is a flat guiding block 534, and the magnetic cores are placed on the top of the feeding conveyor belt 3 and the guiding section 531; the screening section 532 is inclined from the top downwards; on the top of the returning section 533, there is a returning block 535 inclined towards the feeding conveyor belt 3. The magnetic cores are rectangular, and two of the ends of the surface of the magnetic cores are flat, and the other two ends are arc-shaped. When the magnetic cores pass through the screening section 532, only 1 / 3 of the part of the magnetic cores is on the feeding conveyor belt 3, and the other part is in a suspended state. When passing through the screening section 532, the pressing plate 52 can press the flat end of the magnetic cores to make the magnetic cores pass through the screening section 532 smoothly. When the arc surface of the magnetic cores is below the pressing plate 52, since the distance between the pressing plate 52 and the width-limiting block 51 protruding is small, the pressing plate 52 cannot press the magnetic cores. Therefore, when the magnetic cores pass through the screening section 532, they will fall from the inclined surface of the screening section 532 onto the return conveyor belt 8 and return to the feeding conveyor belt 3 to continue the arrangement. Since the difference between the long side and the short side of the magnetic cores is 0.7 mm, limiting the arrangement order of the magnetic cores can prevent jamming during the arrangement process.

[0065] In order to further optimize the above technical solution, two screening limit plates 54 arranged in parallel are provided at the end of the top of the feeding conveyor belt 3, and the screening limit plates 54 are placed at the ends of the return section 533 and the width-limiting block 51. An inclined plate 10 is provided between the end of the feeding conveyor belt 3 and the turning conveyor belt 61, and the magnetic core slides from the inclined plate 10 onto the turning conveyor belt 61, so as to ensure that the magnetic core has a certain angle when it falls onto the turning conveyor belt 61, making it flip more smoothly at the turning plate 62 and preventing jamming.

[0066] In order to further optimize the above technical solution, the turning assembly 6 includes: a turning conveyor belt 61, a turning plate 62 and a turning limit plate 63; the turning conveyor belt 61 is placed below the feeding conveyor belt 3; the turning plate 62 and the turning limit plate 63 are arranged along the conveying direction of the turning conveyor belt 61 and are located at the end of the screening limit plate 54; the turning plate 62 is in a continuous turning inclined shape, one end of the turning plate 62 close to the screening limit plate 54 forms an angle of 60° with the horizontal plane, and the other end of the turning plate 62 forms an angle of 90° with the horizontal plane. The turning limit plate 63 can limit the magnetic core during the turning process to make it arranged neatly.

[0067] In order to further optimize the above technical solution, a first pushing plate 64 and a second pushing plate 65 are arranged along the turning conveyor belt 61 at the end of the turning plate 62. The first pushing plate 64 and the second pushing plate 65 are arranged in parallel and correspond to the open end of the tray 7.

[0068] In order to further optimize the above technical solution, a pushing cylinder 66 is arranged outside the first pushing plate 64. The telescopic end of the pushing cylinder 66 is connected to the first pushing plate 64, and the fixed end is connected to the frame 1; the top of the second pushing plate 65 is connected to a blocking cylinder 67. The telescopic end of the blocking cylinder 67 is connected to the second pushing plate 65, and the fixed end is connected to the first pushing plate 64.

[0069] In order to further optimize the above technical solution, a limit block 68 is arranged at the position of the end of the second pushing plate 65 on the turning conveyor belt 61, and the limit block 68 is placed between the first pushing plate 64 and the second pushing plate 65. The limit block 68 limits the magnetic core to stack the magnetic core between the first pushing plate 64 and the second pushing plate 65.

[0070] To further optimize the above technical solution, two transition plates 69 arranged in parallel are provided between the first pusher plate 64 and the turning plate 62. The transition plates 69 are placed on top of the turning conveyor belt 61. A full - material sensor 610 is provided on the frame 1, and a detection hole 611 is opened at a position corresponding to the detection end of the transition plate 69. The detection hole 611 is located at one end of the transition plate 69 close to the first pusher plate 64 and the second pusher plate 65. When the magnetic cores are stacked up to the detection hole 611 and the full - material sensor 610 detects the magnetic cores, it means that the magnetic cores between the first pusher plate 64 and the second pusher plate 65 are full, and then the first pusher operation can be carried out.

[0071] To further optimize the above technical solution, a control box is also provided on the frame 1. The full - material sensor 610, the pusher cylinder 66, the material - blocking cylinder 67, and the material - shortage sensor 44 are all connected to the controller in the control box for signal transmission.

[0072] Working principle:

[0073] Single - layer and single - row feeding of magnetic cores: The magnetic cores move from the blanking conveyor belt 2 to the feeding conveyor belt 3. Under the guiding action of the guiding plate 41, the magnetic cores gradually move towards the edge of the feeding conveyor belt 3, and the magnetic cores are gradually arranged in a single row. The magnetic cores first pass through the material - shortage baffle 43, and then the material - blocking plate 42 limits the height of the magnetic cores, making the magnetic cores in two or more layers arranged in a single layer. The magnetic cores that fall from the feeding conveyor belt 3 during the movement enter the return conveyor belt 8, and are driven by the return conveyor belt 8 and the return baffle 9 to re - enter the feeding conveyor belt 3.

[0074] Screening process of magnetic cores: After passing through the material - blocking plate 42, the magnetic cores gradually move onto the guiding section 531 of the screening block 53, and then continue to move to the screening section 532. When the arc - surface end of the magnetic core moves below the pressing plate 52, the pressing plate 52 cannot press the magnetic core, and the magnetic core will fall from the screening section 532 onto the return conveyor belt 8, and is driven by the return conveyor belt 8 and the return baffle 9 to re - enter the feeding conveyor belt 3. When the flat - surface end of the magnetic core moves below the pressing plate 52, the pressing plate 52 presses the magnetic core and moves with the feeding conveyor belt 3 to the returning section 533, and then under the drive of the returning block 535, all the magnetic cores enter the feeding conveyor belt 3, and then under the limitation of the screening limiting plate 4, the screened magnetic cores continue to move.

[0075] Turning process: The magnetic cores are limited by the screening limiting block 4 and move to the end of the feeding conveyor belt 3 and then enter the turning conveyor belt 61. When the magnetic cores slide off the feeding conveyor belt 3, they have a certain angle, and then through the drive of the turning plate 62, the angle of the magnetic cores is gradually turned to 90°.

[0076] Pushing process: After the magnetic core is flipped by 90°, it continues to move through the transition plate, moves between the first pushing plate 64 and the second pushing plate 65, and stacks materials under the limiting action of the limiting block 68. When the full material sensor 610 detects that the materials between the first pushing plate 64 and the second pushing plate 65 are full, the pushing cylinder 66 drives the first pushing plate 64 and the second pushing plate 65 to move towards the tray 7. When the movement is in place, the blocking cylinder 67 drives the second pushing baffle 65 to rise, and then the pushing cylinder 66 drives the first pushing baffle 64 and the second pushing baffle 65 to return to their original positions, pushing the magnetic core into the tray 7. The second pushing baffle 65 returns horizontally, and at the same time, the blocking cylinder 67 drives the second pushing baffle 65 to move down to its original position, realizing one-time material pushing.
