Technical Field

[0001] The utility model relates to the technical field of nanocrystalline magnetic core dispensing, in particular to a dispensing machine for producing and processing nanocrystalline magnetic cores. Background Art

[0002] Nanocrystalline cores feature high permeability, high full magnetic induction, low coercivity, and low losses. They are suitable for use in common-mode inductors for EMC / EMI filters, high-frequency transformers, inverters, and current transformers. They are also widely used in new energy applications such as solar inverters and wind power generation. Like conventional amorphous alloys, nanocrystalline materials are primarily used in the manufacture of transformer cores. The nanocrystalline material is first wound into a roll, then wrapped with a coil, and finally encapsulated in an insulating casing. The core encapsulation process typically involves dispensing glue using a dispenser.

When dispensing glue on large quantities of magnetic cores, the workload is large and the dispensing efficiency is low. Utility Model Content

[0023] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-5 The utility model provides a technical solution: a dispensing machine for the production and processing of nanocrystalline magnetic cores, including a conveying mechanism 1 and a dispensing mechanism 2, the dispensing mechanism 2 includes a frame 21, a first linear slide 22 is provided on the frame 21, a second linear slide 23 is provided on the first linear slide 22, a third linear slide 24 is provided on the second linear slide 23, a dispensing assembly 25 is provided on the third linear slide 24, the dispensing assembly 25 includes a dispensing gun 252 and a CCD visual camera 255, the conveying mechanism 1 includes a conveying frame 11 and a conveyor belt 13, a plurality of through holes 15 are provided on the conveyor belt 13, and a negative pressure connecting pipe 16 is provided on the conveying frame 11.

[0025] The nanocrystalline magnetic cores to be glued are placed on the conveying mechanism 1 , and multiple groups of nanocrystalline magnetic cores are conveyed by the conveying mechanism 1 , forming a glue dispensing area between the conveying mechanism 1 and the glue dispensing mechanism 2 .

[0026] When a part of the magnetic core is conveyed to the dispensing area, the conveying mechanism 1 brakes and the CCD vision camera 255 is used as a visual positioning system. The CCD vision camera 255 obtains the image information of the magnetic core, collects the image information and processes the image, and performs position calculations to determine the actual position of the magnetic core. The actual offset value of the magnetic core is calculated by comparing it with the previously set reference position. By controlling the movement of each linear slide, the dispensing gun 252 is driven to the specified position, and the multiple groups of magnetic cores in the dispensing area are sequentially dispensed.

[0027] After the dispensing is completed, the conveying mechanism 1 continues to work, driving the next part of the magnetic core to the dispensing area, and at the same time moving the magnetic core after the dispensing is completed, repeating the above actions to realize continuous dispensing processing of multiple groups of magnetic cores. When performing continuous dispensing processing on the magnetic cores, there is no need to clamp the magnetic cores or position the magnetic cores. It is only necessary to ensure that the surface of the magnetic core to be dispensed is facing up, which saves the time required for clamping and disassembling the magnetic cores, reduces the workload, and improves the dispensing processing efficiency. It is suitable for dispensing processing of large quantities of nanocrystalline magnetic cores.

[0028] The negative pressure connecting pipe 16 of the conveying mechanism 1 is connected to the negative pressure vacuum pump assembly, and the gas is extracted through the pump group, so that the multiple groups of through holes 15 of the conveyor belt 13 generate a certain negative pressure adsorption force. The multiple groups of magnetic cores placed on the conveyor belt 13 are fixed by relying on this negative pressure adsorption force, ensuring the stability of the magnetic cores during the dispensing process, thereby improving the dispensing quality of the magnetic cores.

[0029] There are two groups of first linear slides 22 , which are located on both sides of the frame 21 , and the second linear slide 23 is installed between the two groups of first linear slides 22 .

[0030] The first linear slide 22 is used as a Y-axis slide, the second linear slide 23 is used as an X-axis slide, and the third linear slide 24 is used as a Z-axis slide. The position of the dispensing gun 252 in the Y-axis direction is flexibly adjusted through the first linear slide 22, the position of the dispensing gun 252 in the X-axis direction is flexibly adjusted through the second linear slide 23, and the position of the dispensing gun 252 in the Z-axis direction is flexibly adjusted through the third linear slide 24.

[0031] Among them, the glue dispensing component 25 includes a mounting frame 251, and the mounting frame 251 is fixedly connected to the third linear slide 24 by screws. The glue dispensing component 25 and the third linear slide 24 are detachably connected, which facilitates the installation and disassembly of the glue dispensing component 25 and facilitates maintenance.

[0032] The mounting frame 251 is welded with a side plate 254 , and the CCD visual camera 255 is mounted and fixed on the side plate 254 . The image information of the magnetic core is obtained by the CCD visual camera 255 , and the image information is collected and processed.

[0033] One end of the glue dispensing gun 252 is connected to the glue feeding hose 253 , and the glue liquid required for the glue dispensing operation is delivered to the glue dispensing gun 252 through the glue feeding hose 253 .

[0034] Among them, the conveying mechanism 1 includes a stopper 17, which is fixedly connected to the conveying frame 11. The stopper 17 is located on one side of the conveying mechanism 1. The setting of the stopper 17 makes the position of the conveyor belt 13 outside the stopper 17 have no adsorption force, which is convenient for conveying the magnetic core after the dispensing is completed to the subsequent equipment.

[0035] Among them, a motor reducer 14 is fixedly installed on the conveying frame 11, and the output shaft of the motor reducer 14 is connected to the conveying roller 12. When the motor reducer 14 is working, it drives the conveying roller 12, and drives the conveyor belt 13 to move through the conveyor roller 12, and the magnetic core is transported through the conveyor belt 13.

[0036] The conveying frame 11 is provided with multiple groups of conveying rollers 12 , and the conveying rollers 12 are connected to the conveying frame 11 via bearings.

[0037] A chamber is formed between the conveying frame 11 and the conveying belt 13. The conveying mechanism 1 is connected to a negative pressure vacuum pump assembly, which extracts gas inside the chamber through the pump assembly, so that the multiple groups of through holes 15 of the conveying belt 13 generate a certain negative pressure adsorption force.

[0038] Working principle: When in use, the nanocrystalline magnetic core to be glued is placed on the conveying mechanism 1, and multiple groups of nanocrystalline magnetic cores are conveyed by the conveying mechanism 1. When a part of the magnetic cores is conveyed to the glue-dispensing area, the conveying mechanism 1 brakes, and the CCD vision camera 255 is used as a visual positioning system. The CCD vision camera 255 obtains the image information of the magnetic core, collects the image information, processes the image, and performs position calculations to determine the actual position of the magnetic core. The actual offset value of the magnetic core is calculated by comparing it with the previously set reference position, and the glue gun 252 is driven to the specified position by controlling the movement of each linear slide. The glue dispensing gun 252 is sequentially glued to the multiple groups of magnetic cores in the glue-dispensing area. After the glue-dispensing is completed, the conveying mechanism 1 continues to work, drives the next part of the magnetic cores to the glue-dispensing area, and removes the magnetic cores after the glue-dispensing is completed. The above actions are repeated to achieve continuous glue-dispensing processing of multiple groups of magnetic cores.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
