Description

Technical Field

[0001] The utility model relates to the technical field of earphone box processing, in particular to an automatic fixing tool for magnet assembly equipment. Background Art

[0002] Headphone charging boxes are usually used to store and charge headphones or wireless headphones. Such devices usually have a built-in battery and charging port to charge the headphones and facilitate carrying.

[0003] During the production process of the earphone box, magnets need to be installed on the box cover. The function of the earphone box magnet is to absorb the earphones, so that the earphones are fixed in the box and not easy to fall out. At the same time, the magnet also helps the earphones to connect and charge automatically. When the box cover is closed, the magnet will attract the metal contact of the earphones, so that the earphones and the box are connected, and charging will begin.

[0004] In the process of assembling magnets in the earphone charging box, in order to improve the assembly efficiency, most of the current installation methods are in the form of assembly lines. When operating on the assembly line, it is necessary to fix the tooling tray with the earphone charging box shell installed in a fixed position to facilitate the assembly of the magnet. At present, for fixing the tooling tray on the assembly line, most of the methods used are to stop the tooling tray from moving on the track of the assembly line, so as to achieve the effect of positioning it. However, since the assembly line is still in operation at this time, the track will more or less shake, and then the tooling tray will shake, affecting the assembly effect of the magnet. Therefore, we proposed a magnet assembly equipment with automatic fixing tooling to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the defect in the prior art that the operation of the assembly line will cause the tooling tray to vibrate, thus affecting the installation effect of the earphone charging box magnet, and provides an automatic fixing tooling for magnet assembly equipment.

[0006] The utility model is realized through the following technical solutions:

[0007] An automatic fixing tool for magnet assembly equipment, comprising a driving track and a tooling tray slidably mounted on the driving track, a servo motor is arranged on one side of the driving track, a bracket plate is fixed to the bottom of the driving track, a cylinder is mounted on the bracket plate, a top plate is fixedly connected to the telescopic end of the cylinder, and fixing plates are arranged at the four corners above the top plate, and the fixing plates are fixedly connected to the driving track through brackets;

[0008] Both ends of the support plate are provided with blocking cylinders, and the blocking cylinders are fixed on the driving track through a mounting frame.

[0009] In a preferred embodiment of the present invention, anti-collision blocks are provided at both ends of the tooling tray, and a fixture for installing the earphone charging box shell is fixed on the upper surface of the tooling tray.

[0010] In a preferred embodiment of the utility model, a backstop is further provided between the two blocking cylinders. The backstop is located at one end close to the input port of the driving track, and the backstop is used to effectively prevent the tooling pallet from moving back.

[0011] In a preferred embodiment of the utility model, a guide rod is vertically fixed to the bottom of the top plate, the guide rod passes through the bracket plate, and the guide rod and the bracket plate are slidably matched to improve the stability of the top plate when it rises.

[0012] In a preferred embodiment of the utility model, positioning pins are provided at the four corners of the upper surface of the top plate, and pin holes compatible with the positioning pins are provided on the tooling pallet. When the tooling pallet is pushed through the top plate, the stability during pushing is improved by the cooperation between the positioning pins and the pin holes.

[0013] The beneficial effects of the utility model are:

[0014] The device blocks the tooling pallet moving to the installation position through a blocking cylinder. At the same time, the top plate is driven up by the cylinder at the bottom, which pushes the tooling pallet up and positions it together with the fixed plate, so that the tooling pallet is separated from the drive track, thereby reducing the factors causing the tooling pallet to shake due to the operation of the assembly line and improving the installation accuracy of the magnet in the earphone charging box.

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0021] like Figure 1-4 An automatic fixing tool for magnet assembly equipment shown in the figure comprises a driving track 1 and a tooling tray 2 slidably mounted on the driving track 1, a servo motor 3 is arranged on one side of the driving track 1, a sprocket is arranged on the servo motor 3, a chain and a conveyor belt are arranged inside the driving track 1, and the conveyor belt is conveyed by the cooperation of the sprocket and the chain, thereby conveying the tooling tray 2;

[0022] Among them, anti-collision blocks are provided at both ends of the tooling tray 2, and a fixture 4 for installing the housing of the earphone charging box is fixed on the upper surface of the tooling tray 2. The provision of the anti-collision blocks can reduce the damage caused by the impact of the tooling tray 2 during the movement;

[0023] Secondly, a bracket plate 7 is fixed to the bottom of the driving track 1, and a cylinder 8 is installed on the bracket plate 7. The telescopic end of the cylinder 8 is fixedly connected to a top plate 9. A guide rod 10 is vertically fixed to the bottom of the top plate 9. The guide rod 10 passes through the bracket plate 7, and the guide rod 10 and the bracket plate 7 are slidably matched to improve the stability of the top plate 9 when it rises. Positioning pins 91 are provided at the four corners of the upper surface of the top plate 9, and pin holes matched with the positioning pins 91 are provided on the tooling tray 2. When the tooling tray 2 is pushed through the top plate 9, the cooperation between the positioning pins 91 and the pin holes improves the stability during pushing. Fixed plates 5 are provided at the four corners above the top plate 9, and the fixed plates 5 are fixedly connected to the driving track 1 through the bracket;

[0024] Furthermore, blocking cylinders 6 are provided at both ends of the bracket plate 7, and the blocking cylinders 6 are fixed to the driving rail 1 through a mounting frame. At the same time, a backstop 11 is provided between the two blocking cylinders 6, and the backstop 11 is located at one end close to the input port of the driving rail 1. The backstop 11 can effectively prevent the tooling pallet 2 from moving back.

[0025] In this embodiment, the tooling tray 2 is transported by the driving track 1. After it moves to the specified position, it is blocked by the blocking cylinder 6. At the same time, the operation of the cylinder 8 drives the top plate 9 to rise, and pushes the tooling tray 2 to rise so that it fits with the bottom of the fixed plate 5. The tooling tray 2 is positioned by the cooperation of the cylinder 8 and the fixed plate 5, so that the tooling tray 2 is separated from the driving track 1, thereby reducing the factors causing the tooling tray 2 to shake due to the operation of the assembly line and improving the installation accuracy of the magnet in the earphone charging box.
