Abstract
Description
Technical Field
[0001] The utility model relates to the field of magnetic core processing equipment, in particular to an RM type magnetic core feeding direction adjusting mechanism. Background Technique
[0002] Before leaving the factory, magnetic cores need to be screened and detected by a CCD vision detection system to quickly batch detect various surface defects of magnetic cores using vision recognition algorithms. In order to improve the CCD detection efficiency, it is necessary to arrange magnetic core products neatly and in a unified direction. Especially for irregular products such as RM type magnetic cores, during the feeding process, after simple sorting, RM type products will naturally present a densely misaligned arrangement. In this arrangement, the mutual occlusion between magnetic cores is very serious, which is not conducive to the normal progress of machine vision recognition. Therefore, a device is needed to automatically adjust the misaligned and irregularly shaped RM type magnetic core products into a state of unified direction and neat arrangement for subsequent CCD vision detection processes.

[0006] According to one aspect of the utility model, the inlet end bar is shorter than the outer side bar; an inlet is arranged on the side of the inlet end bar away from the brush disk.
[0007] According to one aspect of the utility model, the inlet end bar is parallel to the outer side bar; the outlet end bar is parallel to the outer side bar.
[0008] According to one aspect of the utility model, the inlet end bar and the outlet end bar are provided with inclined surfaces with the hypotenuse facing the brush disk on the side facing the brush disk.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] Example 1
[0019] like Figure 1As shown, an RM type magnetic core feeding direction adjustment mechanism includes a conveyor belt 1, a product channel and a direction adjustment mechanism, the product channel includes an outer baffle 21, an inlet baffle 22 and an outlet baffle 23; the inlet baffle 22 and one side of the outer baffle 21 form an inlet channel 24; the outlet baffle 23 and the other side of the outer baffle 21 form an outlet channel 25; the direction adjustment mechanism is arranged between the inlet baffle 22 and the outlet baffle 23, and includes a brush disk 31 and a drive motor; the brush disk 31 is disc-shaped, its rotation axis is perpendicular to the conveyor belt 1 and is connected to the drive shaft of the drive motor; the width of the outlet channel 25 is narrower than the inlet channel 24; when the brush disk 31 rotates, the bristles close to the side of the transmission belt swing from the inlet baffle 22 to the outlet baffle 23;
[0020] The direction of travel of the conveyor belt 1 is from the entry-end baffle 22 to the exit-end baffle 23; the entry-end baffle 22 is shorter than the outer baffle 21; the side of the entry baffle 22 away from the brush plate 31, that is, the gap formed by the entry baffle 22 being shorter than the outer baffle 21, just forms the feed port 26, and the densely staggered RM type magnetic core products are transferred from the feed port 26 to the conveyor belt 1. Under the drive of the conveyor belt 1 and the constraint of the feed channel 24, they are roughly arranged in a straight line. At this time, the orientation of the magnetic core products is roughly uniform but they are densely staggered. The mutual obstruction of the magnetic cores is relatively serious, which is not conducive to batch machine vision recognition and detection, and will affect the accuracy and speed of surface quality detection, and reduce the production efficiency of the magnetic cores.
[0021] When densely staggered single-row core products (such as Figure 1 On the left side of the middle brush disc 31, when the magnetic core arrangement shown in the feeding channel 24 passes through the brush disc 31, under the tossing of the rotating brush disc 31, the magnetic core product is biased towards a corner of the brush disc 31 and is forced to swing toward the outer baffle 21. Its direction returns to the right and at the same time, it is distanced from the adjacent magnetic core behind and enters the discharge channel 25. The width of the discharge channel 25 is slightly wider than the width of the magnetic core product, thereby constraining the direction of the magnetic core, so that the magnetic core can be arranged in a straight state (that is, the length direction of the magnetic core product is parallel to the forward direction of the conveyor belt 1 and is connected end to end and lined up in a row, as shown in FIG. Figure 1 On the right side of the middle brush disc 31, the magnetic core arrangement shown in the discharge channel 25 is convenient for the subsequent CCD visual inspection procedure and improves the inspection accuracy and efficiency.
[0022] The inlet baffle 22 is parallel to the outer baffle 21; the outlet baffle 23 is parallel to the outer baffle 21; the bristles of the brush disk 31 need to be of a certain length, wherein the width of the inlet channel 24 is just enough to allow the staggered magnetic cores to pass through in a single row, and the width of the outlet channel 25 is slightly wider than the width of the magnetic core products, which is just enough to allow the magnetic cores connected end to end and arranged in a line to pass through in a single row, so as to ensure that every magnetic core product passing by the brush disk 31 can contact the bristles and be moved by the bristles.
[0023] When the staggered magnetic cores pass through the brush disk 31, the bristles of the brush disk 31 are soft and elastic, and the weight difference between the magnetic cores is very small. When the speed of the brush disk 31 is appropriate, the swinging bristles can instantly straighten the tilted and staggered magnetic cores to a straight arrangement state, which is stable and efficient. Moreover, since the bristles are soft, the short-term friction with the magnetic cores will not damage the surface of the magnetic cores.
[0024] In order to reduce interference with the brush disc 31 , the inlet stop bar 22 and the outlet stop bar 23 are provided with an inclined surface with the oblique edge facing the brush disc 31 on the side facing the brush disc 31 , so as to make space for the rotation of the brush disc 31 .
[0025] Example 2
[0026] like Figure 2 As shown, an RM type magnetic core feeding direction adjustment mechanism includes a conveyor belt 1, a product channel and a direction adjustment mechanism, the product channel includes an outer baffle 21, an inlet baffle 22 and an outlet baffle 23; the inlet baffle 22 and one side of the outer baffle 21 form an inlet channel 24; the outlet baffle 23 and the other side of the outer baffle 21 form an outlet channel 25; the direction adjustment mechanism is arranged between the inlet baffle 22 and the outlet baffle 23, and includes a brush disk 31 and a drive motor; the brush disk 31 is disc-shaped, its rotation axis is perpendicular to the conveyor belt 1 and is connected to the drive shaft of the drive motor; the width of the outlet channel 25 is narrower than the inlet channel 24; when the brush disk 31 rotates, the bristles close to the side of the transmission belt swing from the inlet baffle 22 to the outlet baffle 23;
[0027] The direction of travel of the conveyor belt 1 is from the entry-end baffle 22 to the exit-end baffle 23; the entry-end baffle 22 is shorter than the outer baffle 21; the side of the entry baffle 22 away from the brush plate 31, that is, the gap formed by the entry baffle 22 being shorter than the outer baffle 21, just forms the feed port 26, and the densely staggered RM type magnetic core products are transferred from the feed port 26 to the conveyor belt 1. Under the drive of the conveyor belt 1 and the constraint of the feed channel 24, they are roughly arranged in a straight line. At this time, the orientation of the magnetic core products is roughly uniform but they are densely staggered. The mutual obstruction of the magnetic cores is relatively serious, which is not conducive to batch machine vision recognition and detection, and will affect the accuracy and speed of surface quality detection, and reduce the production efficiency of the magnetic cores.
[0028] A pushing device is set here to move the densely staggered magnetic core products in batches to the conveyor belt 1 in rows. Under the obstruction of the outer baffle 21 and the drive of the conveyor belt 1, the densely staggered arrangement is maintained and the products enter the feeding channel 24 in a straight queue. When the densely staggered single-row magnetic core products (such as Figure 2On the left side of the middle brush disc 31, when the magnetic core arrangement shown in the feeding channel 24 passes through the brush disc 31, under the tossing of the rotating brush disc 31, the magnetic core product is biased towards a corner of the brush disc 31 and is forced to swing toward the outer baffle 21. Its direction returns to the right and at the same time, it is distanced from the adjacent magnetic core behind and enters the discharge channel 25. The width of the discharge channel 25 is slightly wider than the width of the magnetic core product, thereby constraining the direction of the magnetic core, so that the magnetic core can be arranged in a straight state (that is, the length direction of the magnetic core product is parallel to the forward direction of the conveyor belt 1 and is connected end to end and lined up in a row, as shown in FIG. Figure 2 On the right side of the middle brush disc 31, the magnetic core arrangement shown in the discharge channel 25 is convenient for the subsequent CCD visual inspection procedure and improves the inspection accuracy and efficiency.
[0029] The inlet baffle 22 is parallel to the outer baffle 21; the outlet baffle 23 is parallel to the outer baffle 21; the bristles of the brush disk 31 need to be of a certain length, wherein the width of the inlet channel 24 is just enough to allow the staggered magnetic cores to pass through in a single row, and the width of the outlet channel 25 is slightly wider than the width of the magnetic core products, which is just enough to allow the magnetic cores connected end to end and arranged in a line to pass through in a single row, so as to ensure that every magnetic core product passing by the brush disk 31 can contact the bristles and be moved by the bristles.
[0030] When the staggered magnetic cores pass through the brush disk 31, the bristles of the brush disk 31 are soft and elastic, and the weight difference between the magnetic cores is very small. When the speed of the brush disk 31 is appropriate, the swinging bristles can instantly straighten the tilted and staggered magnetic cores to a straight arrangement state, which is stable and efficient. Moreover, since the bristles are soft, the short-term friction with the magnetic cores will not damage the surface of the magnetic cores.
[0031] In order to reduce interference with the brush disc 31 , the inlet stop bar 22 and the outlet stop bar 23 are provided with a concave arc surface with the arc edge facing the brush disc 31 on the side facing the brush disc 31 , so as to make space for the rotation of the brush disc 31 .
[0032] Advantages of the implementation of this utility model:
[0033] By cleverly utilizing the constraints of the feeding and discharging channels and cooperating with the rotating brush disk, the densely staggered magnetic cores can be automatically adjusted to a state of being connected end to end and arranged in a straight line, while maintaining an appropriate distance between adjacent magnetic cores. This is efficient and stable, improving the degree of automation in magnetic core production, and facilitating the subsequent use of machine vision recognition to detect the surface quality of magnetic core products, thereby improving detection and recognition accuracy and efficiency.
