DETAILED DESCRIPTION

[0020] 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.

[0021] The purpose of the present invention is to provide a strong magnet automatic assembly and detection mechanism to solve the problems existing in the above-mentioned prior art, which can complete the automatic assembly and detection in batches, improve production efficiency, and at the same time ensure the stability of the assembly process and improve the quality of the product.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-5 As shown, this embodiment provides a strong magnet automatic assembly detection mechanism, including a base plate 25, an assembly platform, a clip 2, an X-direction pressing cylinder 13, a Y-direction pressing cylinder 3, an electric cylinder 1 and a magnetic flux detection sensor 11. The assembly platform is slidably mounted on the base plate 25, the clip 2 is fixed on the top of the assembly platform, the strong magnets are arranged in the clip 2, the X-direction pressing cylinder 13 and the Y-direction pressing cylinder 3 are respectively used to press the strong magnets from the X direction and the Y direction; the electric cylinder 1 is used to push and press the strong magnet, and a magnetic flux detection sensor 11 for detecting the magnetic flux of the strong magnet is provided on one side of the clip 2. The qualified strong magnet is pressed into the product or workpiece by the electric cylinder 1.

[0024] Specifically, a mobile cylinder 4, a connecting plate 21 and a linear guide rail 24 are provided on the base plate 25; the assembly platform is fixed on the top surface of the connecting plate 21; the bottom surface of the connecting plate 21 is slidably matched with the linear guide rail 24; the telescopic end of the mobile cylinder 4 is used to drive the connecting plate 21 to move relative to the linear guide rail 24; a buffer 22 is provided on the base plate 25; a buffer connecting block 23 is connected to the buffer 22; the end of the buffer connecting block 23 is used to play a buffering role during the movement of the assembly platform along the linear guide rail 24.

[0025] In this embodiment, a clip pressure plate slot 16 is provided above the clip 2, and the strong magnet is loaded into the clip 2 through the clip pressure plate slot 16; a square detection magnet 17 is provided on one side of the inner cavity of the clip 2, and the square detection magnet 17 is used to determine whether the loading direction of the strong magnet is correct. A strong magnet is placed in the clip pressure plate slot 16, and the strong magnet and the square detection magnet 17 attract each other, indicating that the installation magnetic pole of the strong magnet is correct. If they repel each other, the strong magnet needs to be reloaded in the opposite direction. In addition, an elastic partition bar 18 is provided between two adjacent strong magnets in the inner cavity of the clip 2, which is used to separate the strong magnets and prevent the two magnets from being pushed out at the same time during the compression process of the electric cylinder 1. The partition bar 18 is made of elastic material. When the strong magnet is installed in the clip 2, the partition bar 18 located on the outside of the installed strong magnet is deformed and folded back successively under the action of the newly installed strong magnet. After the position of the newly installed strong magnet is fixed, the partition bar 18 rebounds.

[0026] In this embodiment, the X-direction pressing cylinder 13 and the Y-direction pressing cylinder 3 are both rodless cylinders, and the X-direction push plate 14 of the X-direction pressing cylinder 13 and the Y-direction push block 19 of the Y-direction pressing cylinder 3 are used to press the strong magnet in the clip 2 from the X-direction and the Y-direction respectively. A magnet push connection block 15 is installed on the moving part (i.e., the X-direction push plate 14) of the X-direction pressing cylinder 13. In the initial state, the front end of the magnet push connection block 15 is located inside the clip 2. When the strong magnet is installed in the clip 2 through the clip pressure plate groove 16, the moving part retracts, driving the magnet push connection block 15 to move backward. Each time a strong magnet is installed, the magnet push connection block 15 moves backward once, but the magnet push connection block 15 always maintains a pressing state against the strong magnet; similarly, the Y-direction push block 19 of the Y-direction pressing cylinder 3 also always maintains a pressing state against the strong magnet.

[0027] Further, after the strong magnets are arranged in the clip 2, the strong magnets are detected and automatically loaded. Specifically, a connector 5 is provided at the telescopic end of the electric cylinder 1. The connector 5 is installed with a pulling pressure sensor 7 through a connecting block 6. The other side of the pulling pressure sensor 7 is connected to a pressing block 9 through a pressing connecting block 8. The pressing block 9 is used to push the strong magnet to be pressed into the product or workpiece; when the electric cylinder 1 pushes the front-end strong magnet to the position of the clip bottom plate 10, the magnetic flux detection sensor 11 detects the magnetic flux of the strong magnet, and a waste box is provided on the bottom plate 25 at the front side of the clip 2, and the unqualified strong magnets are collected in the waste box; when the strong magnet is qualified after the detection, the moving cylinder 4 drives the assembly platform forward so that the discharge port of the clip 2 is docked with the mounting platform of the product or workpiece, and the electric cylinder 1 is connected to the pulling pressure sensor 7 to drive the pressing forward. During the pressing process, the pulling pressure sensor 7 determines the size of the pressing force and the linear displacement sensor 12 determines whether the pressing displacement is in place, and outputs the force and displacement curve at the same time, and completes the pressing according to the set pressing parameters.
