DETAILED DESCRIPTION

[0024] The embodiments of the present invention are described in detail below. Figures 1 to 4 An embodiment of the present invention provides a magnet feeding mechanism, comprising a magnet magazine 100, a magnet turntable 200, a detection magnetic pole 220, and a detection sensor 230. The magnet magazine 100 is used to store magnets and is vertically mounted on a frame. The magnets in the magnet magazine 100 can slide downward along a slide within the magnet magazine 100 under the action of gravity. The magnet turntable 200 is rotatably mounted below the magnet magazine 100. The distance between the upper surface of the magnet turntable 200 and the lower end of the magnet magazine 100 is less than the height of a single magnet. The magnet turntable 200 is provided with at least one magnet transfer hole 210. The magnet transfer hole 210 can only accommodate one magnet, ensuring that the magnet transfer hole 210 can only receive and separate one magnet from the magnet magazine 100 at a time. The magnet turntable 200 can rotate under the drive of the rotary drive mechanism 300, causing the magnet transfer hole 210 to move back and forth between the material removal position, the detection position, and the feeding position. The detection pole 220 is arranged below the magnet turntable 200, and the detection sensor 230 is arranged above or below the magnet turntable 200. When the magnet transfer hole 210 is in the material removal position, the magnets in the magnetic magazine 100 can slide into the magnet transfer hole 210 under the action of gravity; when the magnet transfer hole 210 moves to the detection position, the detection pole 220 aligns with the magnet transfer hole 210; when the magnet transfer hole 210 moves to the feeding position, the detection sensor 230 aligns with the magnet transfer hole 210, and can detect whether the magnet transfer hole 210 contains magnets.

[0025] The feeding process of the magnet feeding mechanism of the embodiment of the present invention is as follows: first, the magnet turntable 200 rotates to make the magnet transfer hole 210 come to the material taking position, and the magnet at the bottom end of the magnet magazine 100 just falls into the magnet transfer hole 210 under the action of gravity, and the second magnet at the lower end of the magnet magazine 100 does not completely leave the slide of the magnet magazine 100; then the magnet turntable 200 rotates a certain angle to separate the magnet that falls into the magnet transfer hole 210 from the magnet in the magnet magazine 100, and makes the magnet transfer hole 210 come to the detection position. As long as the direction of the detection pole 220 below the detection position is set to be the same as the direction of the magnetic pole of the required magnet installation, if the magnet in the magnet transfer hole 210 The direction of the magnetic pole is opposite to the required direction. The magnet in the magnet transfer hole 210 will generate a repulsive force with the detection magnetic pole 220 due to the repulsion of the same poles, so that the magnet with the wrong magnetic pole direction is ejected from the magnet transfer hole 210, thereby ensuring that the magnetic pole direction of the magnet fed to the installation mechanism is consistent; finally, the magnet transfer hole 210 arrives at the feeding position as the magnet turntable 200 rotates, and the detection sensor 230 above or below the feeding position detects whether there is a magnet in the magnet transfer hole 210. If there is a magnet, the magnet turntable 200 remains stationary until the magnet installation mechanism removes the magnet in the magnet transfer hole 210; if no magnet is detected, the magnet turntable 200 rotates to return the magnet transfer hole 210 to the material removal position. The magnet feeding mechanism of the embodiment of the utility model can realize the automatic separation and feeding of magnets, and can ensure that the magnetic pole direction of the supplied magnets is consistent, avoiding the installation of magnets with the wrong direction on the product to cause quality problems.

[0026] Reference Figures 1 to 4 In some embodiments, to prevent the magnet from sliding out of the bottom of the magnetic magazine 100 directly after the entire magnet is installed in the magnetic magazine 100, thereby making the magnetic magazine 100 with the magnet installed difficult to move, a certain amount of static friction is required between the inner wall of the magnetic magazine 100 and the magnet to prevent the magnet from sliding out of the magnetic magazine 100 under its own weight. In this case, additional downward pressure is required to be applied to the magnet in the magnetic magazine 100 to allow the magnet to slide out of the magnetic magazine 100. In this embodiment, a counterweight 110 is provided at the top end of the magnet in the magnetic magazine 100. The counterweight 110 can slide downward under the action of gravity, applying pressure to the magnet in the magnetic magazine 100, allowing the magnet to slide smoothly out of the bottom end of the magnetic magazine 100. The counterweight 110 can apply sufficient downward pressure to the magnets in the magnetic magazine 100 to prevent the magnets from sliding out of the magnetic magazine 100 due to insufficient gravity after the number of magnets in the magnetic magazine 100 decreases.

[0027] Reference Figures 1 to 4In some embodiments, in order to reduce the loading frequency of the magnetic magazine 100, multiple magnetic magazines 100 are arranged side by side on the magazine changing mechanism 400. The magnetic magazines 100 can be moved along a tangential direction of the magnetic turntable 200 under the drive of the magazine changing mechanism 400, so that the multiple magnetic magazines 100 are sequentially brought to the top of the material extraction position. Figures 2 to 4 In this embodiment, the magazine changing mechanism 400 includes a magazine changing guide rail 420, a magazine changing screw assembly 440, and a magazine changing drive motor 430. Four magnetic magazines 100 are vertically arranged side by side on a magazine holder 410. The magazine changing guide rail 420 is horizontally arranged on one side of the magnetic turntable 200 along a tangential direction of the magnetic turntable 200. The magazine holder 410 is connected to the slider of the magazine changing guide rail 420. The magazine holder 410 is also connected to the screw nut of the magazine changing screw assembly 440. The output shaft of the magazine changing drive motor 430 is connected to the screw shaft of the magazine changing screw assembly 440. When the magnets in the previous magnetic magazine 100 are completely used up, the magazine changing mechanism 400 drives the next magnetic magazine 100 to the top of the material removal position and feeds the counterweight 110 in the previous magnetic magazine 100 from the upper end into its slideway.

[0028] Reference Figure 1 In this embodiment, to improve the feeding efficiency of the magnet feeding mechanism, four magnet transfer holes 210 are provided on the magnet turntable 200. The four magnet transfer holes 210 are arranged at equal angles on the magnet turntable 200 and are equidistant from the rotation center of the magnet turntable 200. This magnet turntable 200 ensures that after each operation, there are magnet transfer holes 210 above the material removal position, the detection position, and the feeding position. Each time the magnet mounting mechanism removes a magnet from the magnet turntable 200, the magnet turntable 200 rotates 90 degrees, allowing the next magnet transfer hole 210 containing a magnet to reach the feeding position, thereby achieving continuous feeding of the magnet mounting mechanism.

[0029] Reference Figure 1 In this embodiment, in order to facilitate the magnet installation mechanism to absorb the magnet from the magnet transfer hole 210, a through hole is provided at the bottom of the magnet transfer hole 210. The size of the through hole is smaller than the size of the magnet to ensure that the atmospheric pressure on the upper and lower end surfaces of the magnet in the magnet transfer hole 210 is the same. It is understandable that the detection sensor 230 can use light, ultrasound or detection of the magnetic field of the magnet to detect whether there is a magnet in the magnet transfer hole 210 at the feeding position. Figure 3 In this embodiment, the detection sensor 230 adopts an optical fiber sensor. The optical fiber probe of the optical fiber sensor is arranged below the magnet turntable 200. The light emitted by the optical fiber probe can be injected into the magnet transfer hole 210 through the through hole at the bottom of the magnet transfer hole 210, thereby realizing the detection of the magnet in the magnet transfer hole 210.

[0030] Reference Figure 5 and Figure 6 The magnetic glue dispensing machine of the present invention comprises the magnetic feeding mechanism and the magnetic glue dispensing installation platform. The magnetic glue dispensing installation platform is arranged on one side of the magnetic feeding mechanism and is used to absorb the magnet from the feeding position of the magnetic feeding mechanism and install the magnet to a specific position on the product. Figure 5 and Figure 6 In this embodiment, the magnet dispensing installation platform includes a transport track 600, a three-axis worktable 500, a magnet pickup head 700, a dispensing head 900, and a positioning camera 800. The transport track 600 is used to connect with upstream and downstream equipment, receiving products to be processed from upstream equipment and transporting them to the next process equipment after magnet installation. The three-axis worktable 500 is mounted above the transport track 600. The magnet pickup head 700, the dispensing head 900, and the positioning camera 800 are arranged side by side on the three-axis worktable 500, capable of moving along the X, Y, and Z axes in response to the movement of the three-axis worktable 500. The magnet pickup head 700 is used to pick up magnets from the magnet feeding mechanism and install them on the product. The dispensing head 900 is used to apply adhesive to the location on the product where the magnets need to be installed. The positioning camera 800 is used to take photos of the product to determine the magnet installation position.

[0031] Reference Figure 6 In this embodiment, the three-axis work platform includes a Y-axis drive mechanism 510, a gantry support 520, an X-axis drive mechanism 530, and a Z-axis drive mechanism 540. The Y-axis drive mechanism 510 is disposed below the transmission track 600. The gantry support 520 straddles the transmission track 600, and the lower end of the gantry support 520 is connected to the Y-axis drive mechanism 510. The X-axis drive mechanism 530 is horizontally disposed on the gantry support 520, and the Z-axis drive mechanism 540 is disposed on the X-axis drive mechanism 530. In order to improve the installation efficiency of the magnet, the Z-axis drive mechanism 540 includes a dispensing lifting drive mechanism 541 and a suction lifting drive mechanism 542. The dispensing lifting drive mechanism 541, the suction lifting drive mechanism 542 and the positioning camera 800 are arranged vertically side by side on the X-axis drive mechanism 530. The dispensing head 900 is arranged on the dispensing lifting drive mechanism 541, and the magnet suction head 700 is arranged on the magnet lifting drive mechanism, so that the heights of the magnet suction head 700 and the dispensing head 900 can be adjusted independently, avoiding the frequent lifting and lowering movements of the magnet suction head 700 and the dispensing head 900 in order to avoid interference during the movement of the three-axis workbench 500, thereby slowing down the action rhythm of the magnet installation.

[0032] Reference Figure 6In this embodiment, to accommodate products of varying widths, the transport track 600 includes two conveyor belt mechanisms 610 and a spacing adjustment mechanism 620. The two conveyor belt mechanisms 610 are arranged parallel to the spacing adjustment mechanism 620 along the product transport direction. The two conveyor belt mechanisms 610 support the two sides of the product being processed and drive the product through the conveyor belts. The spacing adjustment mechanism 620 is used to adjust the spacing between the two conveyor belt mechanisms 610. In this embodiment, the left conveyor belt mechanism 610 is fixed to one end of the spacing adjustment mechanism 620.
