Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of iron core packaging, and specifically relates to a packaging device for iron core production. Background Technique
[0002] In the field of motor manufacturing, the packaging of the magnetic steel of the motor rotor iron core is a crucial link. The existing automatic packaging devices for the magnetic steel of the motor rotor iron core usually adopt the injection molding method for packaging, that is, injecting liquid glue into the slots of the iron core magnetic steel to achieve the purpose of fixing and protecting the magnetic steel. However, this traditional injection molding method has exposed some problems in practical applications.
[0003] First of all, due to the high viscosity of the glue itself, especially in some packaging applications that require high precision, it is difficult for the glue to quickly and evenly penetrate into the slots of the iron core magnetic steel. This problem of slow penetration speed not only affects the packaging efficiency but also may lead to unstable packaging quality. For example, if the glue is unevenly distributed in the slots, it may cause the magnetic steel to be fixed insecurely or have voids, thereby affecting the performance and life of the motor. Therefore, we propose a packaging device for iron core production. Content of the Utility Model
[0004] A technical problem to be solved by this application is: how to design a structure to solve the problems of slow penetration speed and easy overflow of glue in the injection molding method of the existing automatic packaging device for the magnetic steel of the motor rotor iron core.
[0005] To solve the above technical problems, the embodiment of this application provides a packaging device for iron core production, including an injection molding component, a base, and a tooling fixture. The tooling fixture is longitudinally movably arranged at a position directly below the injection molding component on the base;
[0006] It also includes an elastic jitter component, which is installed on the base and is located below the tooling fixture. A trigger is arranged at the bottom of the tooling fixture. When the tooling fixture moves downward, the elastic jitter component is driven by the trigger to jitter the workpiece.
[0007] In some embodiments, a telescopic rod is arranged at the bottom of the tooling fixture, and the tooling fixture is longitudinally movably installed on the base by using the telescopic rod.
[0008] In some embodiments, the elastic jitter component includes a mounting shaft rotatably installed on the base by using a bearing seat. A lever is fixed on the mounting shaft, and a torsion spring with both ends fixed to the lever and the mounting shaft respectively is sleeved on the mounting shaft;
[0009] The trigger contacts one end of the lever, and during the continuous downward movement of the tooling fixture, the trigger continuously drives the end of the lever to press down and then disengages from the lever.
[0010] In some embodiments, the lever includes two connecting rods that rotate together using a rotating shaft. Each of the two connecting rods is respectively arranged on the base using a mounting shaft, and the actuating member contacts the end of any one of the connecting rods that is away from the other connecting rod.
[0011] In some embodiments, a striking head is provided at one end of the connecting rod that is away from the actuating member.
[0012] In some embodiments, the actuating member includes a ejector rod installed at the bottom of the tooling fixture. An extrusion block is provided at the end of the ejector rod. The diameter of the extrusion block is larger than that of the ejector rod, and the connecting rod does not contact the ejector rod in the horizontal state.
[0013] In some embodiments, the side of the extrusion block is chamfered.
[0014] The utility model has at least the following beneficial effects:
[0015] Through the longitudinal movement design of the tooling fixture, the position of the iron core magnet can be accurately controlled to ensure its stability during the potting process. At the same time, the introduction of the elastic jitter component can slightly jitter the workpiece during the potting process, helping the glue to penetrate into the magnet groove more quickly and evenly, significantly improving the encapsulation efficiency, and avoiding problems such as loose magnet fixation or voids caused by uneven glue distribution.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0021] Embodiment 1
[0022] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a packaging device for iron core production. This device realizes the efficient and stable packaging of the iron core magnet through a combination of glue injection and jitter. The device mainly consists of a glue injection component 1, a base 2, a tooling fixture 3, an elastic jitter component 5, etc., ensuring that the glue can uniformly and quickly penetrate into the magnet groove during the packaging process, thereby improving the packaging efficiency and product quality. Its main components are as follows:
[0023] Glue injection component 1: Responsible for injecting liquid glue into the groove of the iron core magnet to fix and protect the magnet. The glue injection component 1 needs to have the ability to precisely control the glue injection volume and speed to ensure the packaging quality. In addition, it should be noted that the glue injection component 1 is installed on a glue injection machine (not involved in the content protected by this solution and not shown in the figure). The glue injection is carried out by pressing down through the glue injection drive unit on the glue injection machine to contact the workpiece;
[0024] Base 2: As the support structure of the device, it is installed on a glue injection machine (not involved in the content protected by this solution and not shown in the figure), bearing and fixing other components. The base 1 needs to have sufficient strength and stability to ensure the smoothness and safety of the device during operation;
[0025] Tooling fixture 3: Used to clamp the iron core magnet and realize its longitudinal movement during the packaging process. The tooling fixture 3 needs to have the ability to precisely control the position of the iron core magnet to ensure its stability during the glue injection process. An expansion rod 6 is provided at the bottom of the fixture, and it is connected to the base 1 through the expansion rod 6 to realize the longitudinal movement of the fixture;
[0026] Elastic jitter component 4: Located below the tooling fixture 3, used to jitter the iron core magnet during the packaging process. The jitter component includes a mounting shaft 7, a lever 8, a torsion spring 9, etc. The mounting shaft 7 is rotatably installed on the base 1 through a bearing seat. The lever 8 is fixed on the mounting shaft 7, and the torsion spring 9 is sleeved on the mounting shaft 7, with both ends fixed to the lever 8 and the mounting shaft 7 respectively, providing a restoring force for the lever 8;
[0027] It should be noted that the lever 8 includes two connecting rods 81 that are rotatably connected together by a rotating shaft. Both connecting rods 81 are respectively arranged on the base 2 by using a mounting shaft 7, and any one or both of the connecting rods 81 can be of telescopic design, so that the connecting adjacent segments can be telescopic. In this way, during the deflection angle process of the two connecting rods 81, the telescopic amount can be compensated to ensure its stable deflection angle. The actuating part 5 contacts the end of any connecting rod 81 away from the other connecting rod 81. In this way, when the tooling fixture 3 moves downward, it drives the knocking section of the lever 8 to press down, so that the torsion spring 9 can be used to drive it to bounce up to knock the bottom of the tooling fixture 3, so as to vibrate the workpiece to accelerate the glue injection;
[0028] Trigger part 5: Installed at the bottom of the tooling fixture 3, used to drive the elastic jitter part 4 to jitter the workpiece when the fixture moves downward. The trigger part 5 includes a push rod 11 and a pressing block 12. The push rod 11 is installed at the bottom of the fixture, and the pressing block 12 is fixed at the end of the push rod 11. The diameter of the pressing block 12 is larger than that of the push rod 11 to ensure that it does not contact the push rod 11 in the horizontal state of the lever 8, so as not to interfere with the rapid reset of the connecting rod 81, thereby ensuring effective knocking vibration. In addition, the side of the pressing block 12 is chamfered to facilitate the contact and separation from the lever 8.
[0029] Specifically, during the encapsulation process, the tooling fixture 3 clamps the iron core magnet and moves vertically downward to the lower part of the glue injection component 1. When the fixture moves downward to a certain position, the pressing block 12 on the push rod 11 contacts one end of the lever 8 and drives the end of the lever 8 to press down. As the fixture continues to move downward, the pressing block 12 continuously drives the lever 8 to press down until the lever 8 separates from the pressing block 12. During this process, the other end of the lever 8 generates a reset action under the action of the torsion spring 9, thereby driving the knocking head 10 to jitter the iron core magnet. This jitter helps the glue to penetrate into the magnet groove more quickly and evenly, improving the encapsulation efficiency and product quality.
[0030] Embodiment 2
[0031] Based on the above Embodiment 1, a position sensor can also be installed between the tooling fixture 3 and the glue injection component 1 to monitor the longitudinal movement position of the tooling fixture 3 in real time. By connecting the sensor to the control system, precise glue injection timing control can be achieved. When the tooling fixture 3 moves to the preset position, the control system automatically starts the glue injection component 1 to start the glue injection operation.
[0032] In addition, an acceleration sensor can be installed on the elastic jitter part 4 to monitor the acceleration change during the jitter process in real time. By analyzing the acceleration data, the intensity and frequency of the jitter can be evaluated, and then the jitter parameters can be optimized to further improve the encapsulation efficiency and quality.
[0033] In this way, during the encapsulation process, the tooling fixture 3 clamps the iron core magnet and moves longitudinally to the preset position. After the position sensor detects that the fixture reaches the predetermined position, the control system starts the glue injection component 1 to start the glue injection operation. At the same time, the elastic jitter part 4 jitters the iron core magnet according to the preset jitter parameters during the glue injection process. The acceleration sensor monitors the acceleration change during the jitter process in real time and transmits the data to the control system. The control system adjusts the jitter parameters according to the acceleration data to ensure the best jitter effect.
