DETAILED DESCRIPTION

[0025] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0026] An assembly device for a motor circuit board, such as Figure 1-Figure 6 As shown, it includes a workbench 1, a gantry 11 arranged on the workbench 1, an assembly arm 111 arranged on the gantry 11, a circuit board loading module and a product transplanting module.

[0027] The circuit board loading module includes a loading rack 5 and a material taking module. The material taking module is used to take out the product circuit board in the loading rack 5 to the corresponding position. The loading rack 5 is set on one side of the workbench 1. The transplanting module includes a linear motor module 13 fixedly connected to the workbench 1 and a mobile platform 12 for carrying the product shell. The output end of the linear motor module 13 is fixedly connected to the bottom of the mobile platform 12. The linear motor module 13 is used to control the mobile platform 12 to move in the horizontal direction; the top of the mobile platform 12 is fixedly connected with a plurality of limit plates 121 extending in the vertical direction. The product shell is placed between the plurality of limit plates 121. The setting of the limit plates 121 limits the movement of the product shell in the horizontal direction.

[0028] The material taking module comprises a support frame 2, a lifting arm 23, a material taking plate 31 and a placing plate 32. The support frame 2 is vertically fixedly connected to the workbench 1. Both ends of the support frame 2 are fixedly connected to bearing seats 21. A screw rod 22 is rotatably connected between the two bearing seats 21. A driving block is threadedly connected to the screw rod 22. The driving block is fixedly connected to the lifting arm 23. Vertically arranged lifting guide rails 24 are fixedly connected on both sides of the screw rod 22. Both ends of the lifting arm 23 are fixedly connected to lifting blocks 231 slidably connected to the lifting guide rails 24. The top of the support frame 2 is fixed A first motor 25 is connected, and the output shaft of the first motor 25 extends toward one end of the screw rod 22 and is fixedly connected to the end of the screw rod 22 through a coupling; the first motor 25 is driven to drive the screw rod 22 to rotate. Due to the setting of the lifting guide rail 24 and the lifting block 231, the moving trajectory of the lifting arm 23 is limited, and the rotation freedom of the lifting arm 23 is limited, that is, the rotation freedom of the driving block is limited. The rotation of the screw rod 22 can drive the driving block threaded on the screw rod 22 to move along the axial direction of the screw rod 22, so that the lifting arm 23 is lifted and lowered in the vertical direction.

[0029] A plurality of reinforcing ribs 232 are fixedly connected to the lifting arm 23, and the two ends of the reinforcing ribs 232 extend toward the two sides of the lifting arm 23. A supporting base plate 3 is installed on both sides of the lifting arm 23. The supporting base plate 3 is fixedly connected to the top of the reinforcing ribs 232. A first rodless cylinder 33 is fixedly connected to the top of the supporting base plate 3. The output end of the first rodless cylinder 33 is fixedly connected to the bottom of the feeding plate 31 close to the lifting arm 23. The first rodless cylinder 33 is driven to drive the feeding plate 31 to move along the width direction of the reinforcing ribs 232. The cross-section of the feeding plate 31 is set to be C-shaped. A first slider 34 is fixedly connected to the two sides of the first rodless cylinder 33 at the top of the supporting base plate 3, and the first slider 34 is close to the back of the supporting base plate 3. The first linear guide 311 is fixedly connected to the bottom of the feeding plate 31 and is slidably matched with the first slider 34. The setting of the first slider 34 and the first linear guide 311 limits the movement trajectory of the feeding plate 31, so that the movement of the feeding plate 31 is more stable, and the first linear guide 311 is set at the bottom of the feeding plate 31, so that the feeding plate 31 can move toward the outside of the supporting base plate 3 along the length direction of the lifting arm 23; the top of the supporting base plate 3 is fixedly connected to the supporting roller 35, and the supporting roller 35 is in contact with the bottom of the first linear guide 311. When a part of the feeding plate 31 extends out of the supporting base plate 3, the feeding plate 31 can be well supported by the supporting roller 35, thereby ensuring the service life.

[0030] A second rodless cylinder 312 is fixedly connected to one side of the material picking plate 31, and the output end of the second rodless cylinder 312 is fixedly connected to the placement plate 32. A second linear guide 313 is also fixedly connected to the top of the material picking plate 31, and a second slider 321 that slides with the second linear guide 313 is fixedly connected to the bottom of the placement plate 32. Through the cooperation of the first linear guide 311 and the second slider 321, the movement trajectory of the placement plate 32 is limited, so that the movement of the placement plate 32 is more stable.

[0031] The cross-section of the placement plate 32 is also set to be C-shaped, so that there are two extensions on the placement plate 32 for placing the product circuit board, and each extension is provided with a positioning column 322 that cooperates with the product circuit board, so that the material picking is more accurate, and the movement of the product circuit board can be limited during movement, making the material picking more stable; two photoelectric sensors 36 are fixedly connected to the top of the supporting base plate 3, and a notch that cooperates with the photoelectric sensor 36 is opened on the material picking plate 31. The photoelectric sensor 36 is used to accurately locate the position of the product; a number of hydraulic buffers 4 are fixedly connected to the top of the material picking plate 31 and the top of the supporting base plate 3, which can provide good buffering to prevent the material picking plate 31 and the placement plate 32 from moving too fast and causing collisions, thereby ensuring the service life of the overall structure, and also having a good limiting effect to prevent the material picking plate 31 and the placement plate 32 from continuing to move and causing damage.

[0032] Working principle: drive the first motor 25, the screw rod 22 rotates to drive the drive block threaded on the screw rod 22 to move along the axial direction of the screw rod 22, so that the lifting arm 23 is lifted and lowered to the corresponding position in the vertical direction, drive the first rodless cylinder 33, use the first rodless cylinder 33 to drive the material taking plate 31 to move along the width direction of the reinforcing rib 232, and move toward the inside of the loading rack 5, drive the second rodless cylinder 312, drive the placement plate 32 to move toward the loading rack 5, until the placement plate 32 is located at the bottom of the product circuit board, drive the first motor 25, drive the lifting arm 23 to rise, and the product circuit board is lifted by the slave, continue to control the first rodless cylinder 33 and the second rodless cylinder 312, return to the original position, and the circuit board can be taken out from the loading rack 5; then control the assembly arm 111 to clamp the product circuit board into the product housing on the transplanting module, and use the screw machine on the assembly arm 111 to install and fix the circuit board. The overall structure does not require manual operation, improves work efficiency, and has more accurate positioning and more stable assembly.
