Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, specifically a coil, and more specifically, a production and testing device for a coil with a magnetic core. Background Technology

[0002] Existing technology uses separate equipment. First, the coil is wound. After winding, the coil often falls into a junction box. The coil is then manually placed into a transport fixture for core assembly. Finally, it undergoes image inspection and screening before qualified products are shipped. In this production process, the coil is easily damaged externally because it falls into the junction box after winding. In addition, the process is inefficient, and human error often leads to product damage. Utility Model Content

[0003] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an automatic assembly and inspection production line for rod coils, characterized by: a transfer fixture conveyor belt with an upper end, a lower end, and a right side end; a magnetic core assembly machine is set above both sides of the right transfer fixture conveyor belt; a robot is set between the winding machine and the magnetic core assembly machine; a drying oven is set at the lower end, and the transfer fixture conveyor belt at the lower end passes through the drying oven and reaches the image inspection machine on the left side; a tray area is set at the upper left end, and a tray robot is set between the tray area and the image inspection machine; a semi-circular groove is set at the upper end of the transfer fixture, and a magnetic column is set at the lower end of the semi-circular groove.

[0004] The magnetic core assembly machine includes a magnetic rod transport fixture, a magnetic rod gripper, a robotic arm, and a coil gripper. The magnetic rod transport fixture is connected to a vibrating hopper via a track, and a propulsion cylinder is provided at the rear end of the magnetic rod transport fixture. It also includes a first positioning rod and a second positioning rod, both of which are mounted on a positioning seat.

The robotic arm is located between the winding machine and the first positioning rod and is capable of inserting the coil wound by the winding machine into the first positioning rod. The coil gripper is mounted on a coil gripper seat with XYZR functionality.

[0005] The transfer fixture is mounted on the lower transfer fixture conveyor belt, and the transfer fixture is positioned below the coil gripper.

[0006] The XYZR function refers to a slider with an X-axis direction, a slider with a Y-axis direction on the slider with the X-axis direction, a slider with a Z-axis direction on the slider with the Y-axis direction, a rotating axis on the slider with the Z-axis direction, and a coil gripper or magnetic rod gripper on the rotating axis; X-axis, Y-axis, and Z-axis refer to three axes that are perpendicular to each other in space.

[0007] The advantages of this invention are: the coil will not be damaged when it falls, and the relative position of the coil and the magnetic rod will not change during drying; in addition, it can insert the coil while the magnetic rod is wobbling, preventing interference between the magnetic rod and the coil; furthermore, a two-stage positioning method is used to ensure the accuracy of the coil insertion position.

[0012] The present invention will now be described in detail with reference to the accompanying drawings. As shown in the drawings, the present invention includes a transfer fixture conveyor belt 16 at the upper end, lower end, and right side end. A magnetic core assembly machine is disposed above both sides of the right transfer fixture conveyor belt. A robot arm 22 is disposed between the winding machine 21 and the magnetic core assembly machine. A drying oven 25 is disposed at the lower end. The transfer fixture conveyor belt at the lower end passes through the drying oven and reaches the image inspection machine 23 on the left side. A tray placement area 24 is disposed at the upper left end. A tray placement robot 26 is disposed between the tray placement area 24 and the image inspection machine 23.

[0013] The transfer fixture 1 has a semi-circular groove 101 at its upper end and a magnetic post 102 at its lower end. The assembled coil is placed in the semi-circular groove, and the position of the coil is fixed due to the action of the magnet.

[0014] The magnetic core assembly machine includes a magnetic rod transport fixture 2, a magnetic rod gripper 7, a robotic arm, and a coil gripper 6. The magnetic rod transport fixture 2 is connected to a vibrating hopper 12 via a track 13. The magnetic rods are placed in the vibrating hopper 12, and the magnetic rods are transported to the magnetic rod transport fixture via the track 13 by the rotational vibration of the vibrating hopper. A propulsion cylinder 14 is provided at the rear end of the magnetic rod transport fixture 2 to ensure that the magnetic rod transport fixture 2 moves forward continuously. It also includes a first positioning rod 9 and a second positioning rod 10, both of which are mounted on a positioning seat 15. The positioning seat is fixed to the frame; the length of the second positioning rod is preset according to the specifications of different coils and magnetic rods; the magnetic rod gripper 7 is fixed on the magnetic rod gripper base 8; the magnetic rod gripper base 8 has XYZR functionality; the XYZR functionality refers to having a slider in the X-axis direction, a slider in the Y-axis direction on the slider in the X-axis direction, a slider in the Z-axis direction on the slider in the Y-axis direction, a rotating axis on the slider in the Z-axis direction, and a coil gripper or magnetic rod gripper on the rotating axis; the X-axis, Y-axis, and Z-axis refer to three axes that are perpendicular to each other in space. Generally speaking, the XYZR functionality is a well-known technology and has been widely used in existing robots, so it will not be elaborated further here.

[0015] The robot's manipulator is located between the winding machine and the first positioning rod, and can insert the coil 5 after winding by the winding machine into the first positioning rod 9; the coil gripper 6 is set on the coil gripper seat 11, which also has XYZR function.

[0016] It also includes a transfer fixture 1, which is disposed below the coil gripper 6.

[0017] The transfer fixture is mounted on the lower conveyor belt 16. The direction of movement of the conveyor belt is parallel to the piston direction of the propulsion cylinder 14.

[0018] The principle of the magnetic core assembly machine is as follows: Magnetic rods are conveyed to the magnetic rod transport fixture 2 via the rotational vibration of the vibrating hopper and track 13. The piston of the push cylinder 14 pushes the magnetic rod transport fixture to the designated position, where the magnetic rod gripper clamps the magnetic rod, allowing it to be inserted into the coil held by the coil gripper. During insertion, the magnetic rod gripper utilizes the XYZR function of the gripper seat to prevent wobbling during insertion, thus avoiding interference between the magnetic rod and the coil. After clamping the coil from the first positioning rod, the coil gripper first rotates 180 degrees, gently placing the coil against the second positioning rod to ensure accurate initial positioning. After inserting the magnetic rod, it rotates 180 degrees again, gently placing the magnetic rod against the second positioning rod to ensure accurate positioning. These two positioning steps ensure accurate coil insertion and prevent damage to the coil during insertion. The inserted coil is then placed onto the transfer fixture 1 by the coil gripper 6.
