[0043] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0044] See also Figure 1-10 The present invention provides a magnetic core detection device for realizing multi-directional visual comparison and identification, including a magnetic core straightening conveying component 1 and a turntable conveying mechanism 2, characterized in that: the turntable conveying mechanism 2 is evenly distributed with a plurality of magnetic core positioning grooves 3 around the central circumference of the turntable conveying mechanism 2, a control structure 4 for clamping or adjusting the magnetic core is arranged in the magnetic core positioning groove 3, a plurality of photographing mechanisms 5 for photographing different surfaces of the magnetic core are arranged on the turntable conveying mechanism 2, an angle control mechanism 6 for driving the control structure 4 to drive the magnetic core to rotate the angle is arranged on the turntable conveying mechanism 2, and one of the magnetic cores A transverse channel 7 is arranged above the positioning groove 3, a longitudinal channel 11 connected to the output end of the magnetic core straightening conveying assembly 1 is vertically arranged in the middle of the transverse channel 7, a blanking through hole 10 which can be connected to one of the magnetic core positioning grooves 3 is arranged at one end of the transverse channel 7, an elastic pressing mechanism 9 is arranged above the blanking through hole 10, a transverse push piece 8 is arranged at the other end of the transverse channel 7, a connecting rod mechanism 12 which can move in turn toward the direction of the blanking through hole 10 is arranged between the elastic pressing mechanism 9 and the transverse push piece 8, and a reciprocating connecting rod mechanism 13 is arranged between the turntable conveying mechanism 2 and the elastic pressing mechanism 9;

[0045] When the turntable conveying mechanism 2 rotates, the reciprocating connecting rod mechanism 13 is driven to move and drive the elastic pressing mechanism 9 to reciprocate up and down;

[0046] Workflow:

[0047] The batches of magnetic cores are placed in the magnetic core alignment and conveying assembly 1 for alignment and conveying;

[0048] The magnetic cores are transported one by one into the longitudinal channel 11. When the magnetic cores enter the intersection of the longitudinal channel 11 and the transverse channel 7, they stop moving, and multiple magnetic cores are arranged backward along the longitudinal channel 11 to prevent too many or too few magnetic cores from entering the turntable conveying mechanism 2 and affecting the uniform arrangement;

[0049] The continuously rotating turntable conveying mechanism 2 drives the plurality of magnetic core positioning grooves 3 to simultaneously rotate around the center of the turntable conveying mechanism 2;

[0050] The rotation process of the turntable conveying mechanism 2 will drive the reciprocating connecting rod mechanism 13 to continue to move;

[0051] When the reciprocating connecting rod mechanism 13 moves, it will drive the elastic pressing mechanism 9 to move up and down.

[0052] The elastic pressing mechanism 9 drives the connecting rod mechanism 12 to move during the up and down reciprocating movement, so that the horizontal push member 8 moves left and right along the direction of the horizontal channel 7;

[0053] When one of the magnetic cores in the middle of the transverse channel 7 is pushed by the transverse pusher 8, it will enter the end of the transverse channel 7. At this time, the transverse pusher 8 is reset. During the reset process, the elastic pressing mechanism 9 will press down the magnetic core at the end, assisting in pressing the magnetic core to enter the blanking through hole 10, and finally press it into the magnetic core positioning groove 3 just moved below;

[0054] The elastic pressing mechanism 9 is elastic, which can keep the magnetic core in a better pressed state when it falls into the magnetic core positioning groove 3, so that the downward pressure of the magnetic core can be maintained before the magnetic core positioning groove 3 below moves to the position of the blanking through hole 10;

[0055] After the horizontal pusher 8 is reset, the frontmost magnetic core arranged on the longitudinal channel 11 will enter the front of the horizontal pusher 8 to perform the ejection work, completing a cycle action;

[0056] The magnetic core in the magnetic core positioning groove 3 will be taken away by the turntable conveying mechanism 2, and the magnetic core will move to the bottom of the camera mechanism 5 at a different position;

[0057] Before entering one of the photographing mechanisms 5, the angle control mechanism 6 will adjust the magnetic core to complete a 90° rotation, so that each photographing mechanism can complete a photograph at a different angle of each magnetic core;

[0058] The photos of the magnetic cores after taking photos and sampling will be compared with the terminal standard photos to detect defects and integrity. If the magnetic cores do not meet the requirements, they will enter the next photographing mechanism 5 and be unloaded. The unloaded magnetic cores will enter the unqualified product channel;

[0059] The clamping and releasing of the magnetic core are controlled by the control structure 4. When the previous photographing mechanism detects a failed magnetic core, the terminal will issue a command to control the control structure 4 to complete the releasing command. At this time, the magnetic core in the magnetic core positioning groove 3 automatically falls down and is removed.

[0060] The magnetic core alignment and conveying assembly 1 of the present invention includes a first base 101, on which a screening plate 102 and a discharge funnel assembly 103 are arranged, and an inclined feeding channel 104 is arranged between the discharge funnel assembly 103 and the screening plate 102, and an output channel 105 and a vortex channel 106 are arranged on the screening plate 102, and the output channel 105 and the vortex channel 106 are connected, and a screening identification device 107 for detecting whether the chip is aligned is arranged on the screening plate 102.

[0062] The first photographing device 1071 and the blowing device 1072 are communicatively connected with a comparison module;

[0063] The vortex channel 106 is provided with a vibration mechanism.

[0064] The vibration mechanism of the present invention provides vibration for the vortex channel 106, so that the multiple magnetic cores on the vortex channel 106 gradually move toward the output channel 105;

[0065] The magnetic core will pass through the magnet block 1073 and the first camera device 1071 during the movement;

[0066] When the magnetic core reaches the magnet block 1073, the front and back sides of the magnetic core are determined, and like poles repel each other, while opposite poles attract each other; the repelling magnetic cores are pushed back into the screening disk 102 for rescreening;

[0067] When the magnetic core reaches the first photographing device 1071, the standard picture pre-set by the first comparison module is compared with the photographed picture, and an algorithm is used to determine whether they are the same. If the pictures are not the same, the blowing device 1072 is activated to blow the magnetic core with incorrect placement angle out to the screening plate 102 for re-screening.

[0068] The turntable conveying mechanism 2 of the present invention comprises a second base 201, a driving motor 203 is arranged on the second base 201, and an annular conveying plate 202 is arranged on the driving motor 203;

[0069] There are four photographing mechanisms 5, which are respectively used to photograph the four surfaces of the magnetic core rotating around the X-axis; the four photographing mechanisms 5 are respectively arranged on different sides of the magnetic core positioning groove 3, and are arranged with one magnetic core positioning groove 3 spaced apart.

[0070] The control structure 4 of the present invention comprises a rotor assembly 401 arranged in the magnetic core positioning groove 3, the inner end surface of the rotor assembly 401 is provided with a first clamping surface 402, the inner side of the magnetic core positioning groove 3 is provided with a spacer plate 403, a circular through hole 404 is provided on the spacer plate 403, an adjusting column 405 is movably provided in the circular through hole 404, an annular limiting groove 406 is provided on the circumferential outer wall of the adjusting column 405, an axis control ring 407 is rotatably installed in the annular limiting groove 406, a driving rod 408 is provided at the bottom of the axis control ring 407, a push rod motor 409 is provided on the lower surface of the magnetic core positioning groove 3, the output end of the push rod motor 409 is fixedly connected to the driving rod 408, and a second clamping surface 420 is provided on the outer wall of the adjusting column 405;

[0071] The first clamping surface 402 and the second clamping surface 420 are provided with anti-slip material;

[0072] The adjusting column 405 can move axially in the circular through hole 404 to cooperate with the rotor assembly 401 to clamp or loosen the magnetic core;

[0073] The adjusting post 405 can perform circular rotation in the circular through hole 404; when in the state of clamping the magnetic core, the adjusting post 405, the magnetic core and the rotor assembly 401 rotate synchronously;

[0074] The first clamping surface 402 and the second clamping surface 420 are used to clamp the two sides of the magnetic core to maintain the clamping state of the magnetic core, so that when the first clamping surface 402 rotates, the magnetic core can be driven to rotate at an angle by cooperating with the second clamping surface 420;

[0075] When the second clamping surface 420 rotates, the adjusting column 405 will be driven to rotate accordingly;

[0076] The axial movement of the adjustment column 405 will clamp or loosen the magnetic core;

[0077] The axial movement of the adjusting column 405 is completed by the cooperation and control of the annular limiting groove 406 and the axis control ring 407. When the axis control ring 407 moves axially, it will drive the annular limiting groove 406 to follow the axial movement.

[0078] When the annular limiting groove 406 rotates, it cannot affect the axis control ring 407. Therefore, the axis control ring 407 only affects the axial movement of the annular limiting groove 406, but cannot affect the circumferential rotation movement of the annular limiting groove 406, so that the adjustment column 405 at different axial positions can rotate synchronously with the rotor assembly 401.

[0079] The extension and retraction of the push rod motor 409 is made according to the terminal visual analysis, and the qualified magnetic core will remain in the extended state to keep the clamping and conveying of the magnetic core;

[0082] The width and height dimensions of the limiting square column 603 are equal to the width dimension of the limiting annular groove 602. When the limiting square column 603 enters the limiting annular groove 602, it cannot rotate, ensuring the correct angle of the magnetic core when taking pictures. The limiting square column 603 that enters the position of the making way slot 606 and the arc-shaped rack 605 will adjust the angle. The limiting square column 603 will leave the limiting annular groove 602 and enter the making way slot 606 for adjustment. After the adjustment is completed, it will enter the limiting annular groove 602 again to limit rotation.

[0083] In the present invention, when the rotor assembly 401 rotates to the position of the limiting annular groove 602, the limiting square column 603 is installed in the limiting annular groove 602 to limit the angular rotation of the rotor assembly 401;

[0084] When the rotor assembly 401 rotates to the position of the arc-shaped rack 605, the arc-shaped rack 605 cooperates with the driving gear 604 to drive the limiting square column 603 to rotate at the position of the yielding slot 606, and rotates 90° along with the rotor assembly 401;
