Description

Technical Field

[0001] The utility model relates to the technical field of positioning tooling, and particularly relates to a secondary positioning mechanism for a material box. Background Art

[0002] In the process of electronic product manufacturing, especially in the assembly line operation process, it is often necessary to place products on trays. When placing products on trays, it is necessary to position the material box to ensure the consistency of product placement on the tray. The existing positioning devices have relatively simple structures. When it is necessary to restrict the position of a certain surface, a stop block is added on this surface to meet the restriction. However, when the workpiece to be positioned is relatively complex or has clear surface requirements on the outer side, using a simple combination of multiple stop blocks and multiple cylinders (high cost) to achieve the restriction can no longer meet the requirements. For example, a cosmetic box with a hollow structure has extremely high surface finish requirements and does not allow scratching and extrusion.

[0003] Therefore, to meet such special requirements, it is necessary to develop a type of positioning device that can reduce the extrusion between the workpiece and the outer surface of the positioning device and ensure accurate positioning under uncontrollable conditions.

[0020] Refer to Figures 1 to 3 As shown, the structure of the present utility model is: a secondary positioning mechanism for a material box, including a first linear slide rail 1, a linear servo module 2, and a positioning platform 3 for carrying the material box. The first linear slide rail 1 and the linear servo module 2 are arranged in parallel. One end of the positioning platform 3 is slidably connected to the first linear slide rail 1, and the other end of the positioning platform 3 is fixedly connected to the output end of the linear servo module 2. On the upper surface of the positioning platform 3, a first fixed side 4 and a second fixed side 5 perpendicular to each other are fixedly arranged. On the upper surface of the positioning platform 3, a first moving side 6 and a second moving side 7 parallel to the first fixed side 4 and the second fixed side 5 respectively are movably arranged. At the bottom of the positioning platform 3, two moving side driving members 8 for driving the first moving side 6 and the second moving side 7 to move respectively are arranged. Specifically, the linear servo module 2 drives the positioning platform 3 to move back and forth to facilitate other mechanisms to pick up and place the material box and other mechanisms to arrange the plates. The mechanism is provided with a linear slide rail for guiding the positioning platform 3. The mechanism is provided with 2 fixed sides as the reference for the material box. The moving side driving member 8 includes a servo motor, a synchronous pulley, and a synchronous belt. The bottom of the moving side is fixedly connected to one side of the synchronous belt. Driven by the servo motor, the two moving sides can push the material box for positioning and can also adapt to material boxes of different sizes, with a wider adaptability.

[0021] Refer to Figure 2As shown in the figure, the linear servo module 2 includes a servo motor 201, a ball screw 203 and a second linear slide rail 204. The output end of the servo motor 201 is connected to the ball screw 203 through a coupling 202. A slide table 205 fixedly connected to the positioning platform 3 is slidably arranged on the second linear slide rail 204. A screw nut seat 206 threadedly connected to the ball screw 203 is fixedly installed on the slide table 205. Driving the positioning platform 3 by the linear servo module 2 has the advantages of high precision, simple structure, accurate positioning, fast reaction speed, high sensitivity, safe and reliable operation, long service life, and convenient maintenance.

[0022] Refer to Figure 3 As shown in the figure, a first chute 301 is opened on the positioning platform 3 along the direction parallel to the first fixed side 4, and a second chute is opened along the direction parallel to the second fixed side 5. The first moving side 6 and the second moving side 7 are respectively slidably matched with the first chute 301 and the second chute. Specifically, the first chute 301 and the second chute are opened on the positioning platform 3 to guide the first moving side 6 and the second moving side 7, making the moving sides move more smoothly.

[0023] Furthermore, the first fixed side 4 has an L-shaped structure and a waist-shaped hole is opened at the bottom. Specifically, a bolt threadedly connected to the positioning platform 3 is inserted into the waist-shaped hole. The bolt is used to fix the first fixed side 4.

The positioning sensor is used to sense the position of the positioning platform 3 to ensure that there is no deviation when loading the tray, and the tray inductor is used to sense the tray on the positioning platform 3 to prevent the situation of missing placement.

[0026] During specific use, the linear servo module 2 drives the positioning platform 3 to move back and forth to facilitate other mechanisms to pick up and place the material box and other mechanisms to arrange the trays. When the positioning platform moves to a suitable position, the material box is picked up and placed on the positioning platform 3. There are two fixed sides, which serve as the reference for the material box. Then, the two moving sides can be used to push the material box for positioning and can also adapt to different sizes of the material box.
