Technical Field
[0001] This utility model relates to the field of magnetic core production technology, and more specifically, to a magnetic core stacking and powder spreading device. Background Technology
[0002] In existing technologies, magnetic cores are formed by pressing together powdered raw materials. After pressing, they need to be sintered. High-temperature treatment densifies the material and optimizes its microstructure. In production, magnetic cores are sintered by stacking them on trays. When stacking magnetic cores, some talcum powder needs to be spread between them to prevent the two magnetic cores from sticking together during sintering. Currently, the powder is spread manually, which is rather casual and can still cause the magnetic cores to stick together. Therefore, a technical solution is needed to solve the above problems. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art, to provide a magnetic core stacking and powder spreading device that can spread powder quantitatively and uniformly.

Detailed Implementation
[0021] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0022] like Figures 1-4 As shown, this embodiment discloses a magnetic core stacking and powder spreading device, including a conveyor belt 1 and a powder spreading device 2. There are two conveyor belts 1, which support trays 3 from both sides. Two baffles 4 are provided between the two conveyor belts 1. The two baffles 4 are distributed at both ends of the conveying direction of the conveyor belt 1. The upper end of the baffle 4 is higher than the upper end surface of the conveyor belt 1. The conveyor belt 1 is used to reciprocate the trays 3 located on the conveyor belt 1. Magnetic cores 101 can be stacked layer by layer on the trays 3. The powder spreading device 2 is located in the moving direction of the trays 3. After the conveyor belt 1 drives the trays 3 to place one layer of magnetic cores 101 at one end, the conveyor belt 1 sends the trays 3 to the other end. The powder spreading device 2 spreads powder on the upper end surface of this layer of magnetic cores 101 at the other end. The baffles 4 at both ends can position the extreme positions of the moving ends of the trays 3.
[0023] The powder spreading device 2 includes a powder spreading component 23 that can be raised and lowered. The powder spreading device 2 includes a lifting device 21 and a translation device 22. The lifting device 21 can drive the translation device 22 to move up and down. The powder spreading component 23 is installed on the translation device 22. The translation device 22 drives the powder spreading component 23 to move along the direction of the conveyor belt 1. The lifting device 21 is an electric lifting device that can be adjusted according to the stacking height of the magnetic cores 101 on the tray 3 to control the height of the powder falling from the template 232. Since the powder falling hole 2321 on the template 232 corresponds to a row of magnetic cores 101, after spreading powder on a row of magnetic cores 101, it moves to the top of the next row of magnetic cores 101 through the translation device 22 to spread powder.
[0024] The powder spreading assembly 23 includes two side plates 231, a template 232, a sliding box 233, and a powder storage box 234. The side plates 231 include a plug-in part 2311. Both ends of the template 232 are plugged into the plug-in part 2311. The plug-in part 2311 is provided with a slot 2312. The template 232 is partially inserted into the slot 2312. The plug-in part 2311 is equipped with a locking rod 2313. The locking rod 2313 can fix the template 232 located in the slot 2312. Since the magnetic cores 101 have different shapes and different spacing when arranged, the powder dropping holes 2321 on the template 232 will also be different. The plug-in installation structure of the template 232 can make the template 232 replaceable and suitable for different magnetic cores 101 for powder spreading.
[0025] The template 232 is provided with multiple powder dropping holes 2321, which are arranged to form a ring shape with the same shape as the upper end face of the magnetic core 101. For example, in this embodiment, the magnetic core 101 is a ring shape, and the powder dropping holes 2321 are arranged in a ring. When the powder in the powder dropping holes 2321 falls, it will spread out and fall evenly on the upper end face of the ring of the magnetic core 101 below. The amount of powder falling each time is fixed and related to the thickness of the template 232 and the powder dropping holes 2321.
[0026] The sliding box 233 is slidably connected to the template 232. The sliding box 233 is located on one side of the template 232. The sliding box 233 includes a powder receiving box 2331 and a powder baffle 2332. The template 232 is partially located between the powder receiving box 2331 and the powder baffle 2332. The sliding box 233 is capable of translation. The sliding box 233 is slidably connected to the side plate 231. The powder spreading component 23 includes a cylinder 235. The cylinder 235 drives the sliding box 233 to translate. When the sliding box 233 moves, the powder receiving box 2331 and the powder baffle 2332 are slidably connected. When 332 is positioned above and below the powder discharge hole 2321 respectively, the powder in the powder receiving box 2331 enters the powder discharge hole 2321. The powder discharge hole 2321 is sealed below by the powder baffle plate 2332, so that the powder discharge hole 2321 contains powder. When the cylinder 235 drives the sliding box 233 to retract, the sliding box 233 is offset from the powder discharge hole 2321, and the powder baffle plate 2332 leaves the bottom of the powder discharge hole 2321, so that the powder can fall directly from the powder discharge hole 2321 onto the upper surface of the magnetic core 101.
[0027] Template 232 includes guide plate 2322, which extends toward sliding box 233. A guide groove 2333 is formed between powder receiving box 2331 and powder baffle plate 2332. Guide plate 2322 is located in guide groove 2333. An insertion structure is formed between guide plate 2322 and powder receiving box 2331. Since guide plate 2322 is thin, the guide groove 2333 and guide plate 2322 are always inserted to prevent template 232 from deforming and bending downward in the middle.
[0028] The powder storage box 234 is located above the sliding box 233. The powder storage box 234 includes a powder storage groove 2341 and is used to pre-store powder. The powder receiving box 2331 includes a powder receiving groove 23311 and a powder blocking end face 23312. When the cylinder 235 pushes out the sliding box 233, the powder receiving groove 23311 is aligned with the powder drop hole 2321, and the powder blocking end face 23312 closes the lower end of the powder storage groove 2341, which can seal the lower end of the powder storage groove 2341 to prevent powder leakage. When the cylinder 235 retracts the sliding box 233, the lower end of the powder storage groove 2341 is connected to the powder receiving groove 23311, which can replenish the powder receiving groove 23311.
[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
