[0067] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. For the embodiments applied to the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0068] To solve the technical problem in the prior art that when powder materials are filled, it is difficult to fill the later - filled part of the materials, and the materials in the cavity cannot be filled compactly, the present invention provides a vibration and dispersion plate. It presses the carrier plate onto the vibration assembly through a blanking fixture, and performs blanking through the blanking fixture. It uses the vibration assembly to vibrate the powder materials already filled in the cavity of the carrier plate, and uses a combination of vibration and angle adjustment to try to vibrate and compact the powder materials already injected into the cavity, so that the materials added later can smoothly and quickly enter the cavity.

[0069] Please refer to Figures 1-6In a specific embodiment, the present invention provides a dispersion plate for filling powder material 100, the dispersion plate comprising a vibration component 1, a blanking fixture 2 and a controller; wherein the vibration component 1 responds to a vibration mode instruction and vibrates according to a preset strategy; the blanking fixture 2 is fixed above the vibration component 1 and vibrates with the vibration component 1; a carrier plate 3 to be filled with material is pressed between the vibration component 1 and the blanking fixture 2, and a feeding port 21 is provided on the blanking fixture 2, and the bottom end of the feeding port 21 is connected to a material model cavity 31 of the carrier plate 3; the controller is used to generate a vibration mode instruction according to the vibration duration of the vibration component 1 and a preset vibration time, and the vibration mode instruction is used to control the vibration component 1 to vibrate according to a preset vibration strategy.

[0070] The vibration modes of the vibration component 1 include low-frequency, high-frequency and other modes, and the vibration mode can be set according to the working conditions. In actual use scenarios, the vibration frequency can also be set in an increasing form, and the control mode can be arranged and combined in the dimensions of vibration direction, vibration duration, etc., so that the powder filling unit density in the cavity can be effectively increased through the combined vibration of low frequency and high frequency, freeing up the volume in the cavity so that the last 1% of filling can be quickly filled.

[0071] In some embodiments, the vibration component 1 includes a base 11, a power component and a vibration plate 13; wherein, there are at least two power components, each of which is dispersedly installed on the base 11, and the controller is used to control each of the power components to act according to a preset action strategy, so that the vibration component 1 vibrates according to the preset vibration strategy; the vibration plate 13 is located above the base 11, and the vibration plate 13 is transmission-connected to the power component.

[0072] In the vibration-dispersion disk provided by the present invention, there are at least two power components, and each of the power components is dispersedly installed on the base 11. Specifically, the power component can be a voice coil motor 12 (VCM). The voice coil motor 12 has low noise and can vibrate in both directions to achieve a gathering and dispersion effect, which is more suitable for the use scenario of the vibration-dispersion disk. Theoretically speaking, the power component is not limited to the voice coil motor 12, and it can also use a servo motor and a cam transmission structure to replace the voice coil motor 12.

[0073] In some embodiments, the dispersion disk is generally configured as a rectangular structure. In order to adapt to the rectangular structure, the power components of the dispersion disk include a first voice coil motor 12, a second voice coil motor 12, a third voice coil motor 12 and a fourth voice coil motor 12 respectively installed at the four corners of the vibration plate 13.

[0074] Further, the distance between the positions of the 4 VCMs (voice coil motors 12) relative to the outer edge of the carrier plate 3 of the upper material mold is 0; specifically, the calculation is based on the material mold cavity of the material; that is, in order to achieve an ideal vibration and dispersion effect, it is necessary to minimize the installation spacing of the voice coil motors 12 and concentrate the vibration energy on the carrier plate 3.

[0075] In some embodiments, the feeding port 21 has a funnel structure, and the opening of the feeding port 21 at one end close to the mold cavity 31 is smaller than the opening at the end far from the mold cavity 31; that is to say, the upper opening of the feeding port 21 is larger than its bottom opening, and the larger upper opening is set to ensure the smooth entry of the material. The volume of the feeding port 21 is greater than or equal to 2 times the volume of the mold cavity 31. In this way, the feeding amount of the feeding port 21 is calculated based on the multiple of the volume of the mold cavity, which can effectively prevent dust from flying. Generally, the capacity of the feeding funnel should be designed to be not less than 2 times the volume of the mold cavity to prevent dust from flying caused by overflow during vibration.

[0076] On the basis of the above specific embodiments, in order to further improve the filling effect of the cavity, while the vibration assembly 1 is vibrating, angle adjustment can also be added, so that the vibration and the swing of the angle adjustment cooperate with each other.

[0077] In some embodiments, the vibration and dispersion plate further includes a support base 4 and an angle adjustment mechanism. The angle adjustment mechanism is disposed between the support base 4 and the vibration assembly 1. The angle adjustment mechanism acts in response to an angle adjustment instruction to rotate the vibration assembly 1 relative to the support base 4 by a preset angle; the controller is further configured to generate an angle adjustment instruction according to the vibration duration and the preset vibration time, and the angle adjustment instruction is used to control the action of the angle adjustment mechanism.

[0078] In this way, during the vibration of the vibration assembly 1, the angle value can also be adjusted according to the vibration duration, so that the powder material 100 in the cavity can swing through angle adjustment while vibrating, improving the compaction effect.

[0079] It should be understood that the vibration of the vibration assembly 1 and the angle adjustment of the angle adjustment mechanism can be controlled separately, and there is no exclusion relationship between the two; that is to say, whether the vibration assembly 1 vibrates does not affect the action of the angle adjustment mechanism, and vice versa.

[0080] Specifically, the angle adjustment mechanism includes an angle adjustment oil cylinder 51. The cylinder barrel of the angle adjustment oil cylinder 51 is rotatably connected to the support base 4, and the telescopic rod of the angle adjustment oil cylinder 51 is fixedly connected to the vibration assembly 1.

[0081] The angle adjustment mechanism further includes a first mounting seat, a second mounting seat, and a third mounting seat. Among them, the first mounting seat and the second mounting seat are arranged on the support seat 4, the third mounting seat is arranged on the base 11, the bottom of the cylinder barrel of the angle adjustment oil cylinder 51 is hinged to the first mounting seat, the middle or top of the cylinder barrel is hinged to the second mounting seat, and the mounting height of the cylinder barrel on the second mounting seat is higher than the mounting height of the cylinder barrel on the first mounting seat. The end of the telescopic rod of the angle adjustment oil cylinder 51 (i.e., the end far from the cylinder barrel) is hinged to the third mounting seat, and the mounting height of the telescopic rod on the third mounting seat is higher than the mounting height of the cylinder barrel on the second mounting seat. In this way, through the above mounting structure, the angle adjustment oil cylinder 51 is inclinedly arranged between the vibration assembly 1 and the support seat 4. When the telescopic rod extends relative to the cylinder barrel, it can push the vibration assembly 1, the carrier plate 3 on the vibration assembly 1, and the jig to tilt synchronously, so as to provide an appropriate tilt angle for the material in the cavity of the carrier plate 3, enabling the material to move towards the lower side and cooperate with vibration to achieve material compaction. Moreover, when the angle adjustment oil cylinder 51 reciprocates, it can provide a reciprocating swinging motion for the carrier plate 3. Through vibration plus swinging, the filling powder can be effectively filled into every corner of the cavity.

[0082] Further, in order to improve the structural stability of the vibration-dispersing plate, a support structure can also be arranged between the vibration assembly 1 and the support seat 4, and the support structure should not interfere with the swinging of the vibration assembly 1 relative to the support seat 4. For example, as Figure 5 shown, the support structure includes a mounting seat, a rotating shaft, and a rotating block. Among them, the mounting seat is fixed on the support seat 4, the rotating shaft is installed on the mounting seat through a bearing, the rotating block is fixedly connected to the rotating shaft and can rotate with the rotating shaft, and the rotating block is fixed to the bottom of the vibration assembly 1. When the vibration assembly 1 rotates relative to the support seat 4 under the drive of the angle adjustment oil cylinder 51, the rotating shaft will follow without interfering with the angle adjustment. Two groups of support structures can be arranged, respectively on both sides of the angle adjustment oil cylinder 51.

[0083] In some embodiments, the angle adjustment mechanism further includes a horizontal limit member 52 and an angle limit member 53. There are two horizontal limit members 52, both of which are installed between the support seat 4 and the vibration assembly 1 and are respectively arranged on both sides of the angle adjustment oil cylinder 51; the angle limit member 53 is arranged between the cylinder barrel of the angle adjustment oil cylinder 51 and the support seat 4 to limit the maximum rotation angle of the vibration assembly 1.

[0084] In a specific usage scenario, the maximum rotation angle can be 22.5°. After feeding at the feeding port 21, the vibrating and spreading plate is in a horizontal state and preferentially enters the vibration mode. At this time, the vibrating powder jumps above the funnel and freely falls just above and inside the funnel opening, effectively preventing spillage. When vibrating horizontally for a certain period of time, the powder in the funnel has less than half of the original feeding amount left. At this time, combined with the reciprocating tilting motion, when tilted to the maximum angle of 22.5°, the powder in the funnel is just horizontal, so as not to spill.

[0085] Furthermore, the vibrating and spreading plate further includes a pressing mechanism, and the blanking fixture 2 is pressed against the vibration assembly 1 through the pressing mechanism. In order to ensure a firm connection between the carrier plate 3 and the vibration assembly 1, an external force needs to be applied to the carrier plate 3 during the production process to achieve pressing of the carrier plate 3. In this embodiment, the pressing mechanism can be at least one external cylinder assembly, and the pressing cylinder 6 is used to provide a downward pressing force.

[0086] In the above specific embodiment, the vibrating and spreading plate provided by the present invention for powder material 100 filling includes a vibration assembly 1, a blanking fixture 2, and a controller; wherein, the vibration assembly 1 responds to a vibration mode command and vibrates according to a preset strategy; the blanking fixture 2 is fixed above the vibration assembly 1 and vibrates with the vibration assembly 1; the carrier plate 3 of the material to be filled is pressed between the vibration assembly 1 and the blanking fixture 2, and a feeding port 21 is formed on the blanking fixture 2, and the bottom end of the feeding port 21 is communicated with the material model cavity 31 of the carrier plate 3; the controller is used to generate a vibration mode command according to the vibration duration of the vibration assembly 1 and the preset vibration moment, and the vibration mode command is used to control the vibration assembly 1 to vibrate according to a preset vibration strategy. In this way, during the filling process of the powder material 100, by applying vibration to the blanking fixture 2 and the carrier plate 3, the powder material 100 that has fallen into the material model cavity 31 can be compacted as much as possible; and the powder material 100 near the feeding port 21 can be quickly dropped into the material model cavity 31 through vibration, ensuring the filling efficiency and filling amount of the material. It solves the technical problems that when filling the powder material 100 in the prior art, it is difficult to fill the later-fed part of the material, and the material in the cavity cannot be filled solidly.

[0087] In addition to the above vibrating and spreading plate, the present invention also provides a mode control method for controlling the vibrating and spreading plate, as Figure 7 shown, the method includes the following steps:

[0088] S710: Obtain the vibration duration and preset vibration moment of the vibrating and spreading plate;

[0089] S720: Generate a start instruction when the duration of the vibration reaches a duration threshold, where the start instruction is used to control the vibration component to start vibrating;

[0090] S730: Generate an angle adjustment instruction when the vibration component starts vibrating and the preset vibration moment reaches a preset moment node, where the angle adjustment instruction is used to control the angle adjustment mechanism to act according to a preset adjustment strategy.

[0091] Specifically, when the vibration component starts vibrating and the preset vibration moment reaches a preset moment node, generating an angle adjustment instruction, where the angle adjustment instruction is used to control the angle adjustment mechanism to act according to a preset adjustment strategy, specifically including:

[0092] The preset moment nodes sequentially include a first moment node t1, a second moment node t2, a third moment node t3, and a fourth moment node t4 from first to last;

[0093] The duration of the vibration includes a first vibration duration T1, a second vibration duration T2, a third vibration duration T3, a fourth vibration duration T4, and a fifth vibration duration T5;

[0094] When the first vibration duration T1 reaches a first threshold, start the vibration component and the angle adjustment mechanism so that the vibration component rotates a first preset angle in a first direction;

[0095] When the preset vibration moment reaches the first moment node t1, generate a first angle adjustment instruction, where the first angle adjustment instruction is used to control the angle adjustment mechanism to stop moving;

[0096] Obtain the second vibration duration T2, and when the second vibration duration T2 reaches a second threshold, start the angle adjustment mechanism so that the vibration component rotates a second preset angle in the first direction;

[0097] When the preset vibration moment reaches the second moment node t2, generate a second angle adjustment instruction, where the second angle adjustment instruction is used to control the angle adjustment mechanism to stop moving;

[0098] Obtain the third vibration duration T3, and when the third vibration duration T3 reaches a third threshold, start the angle adjustment mechanism so that the vibration component rotates the second preset angle in a second direction, where the second direction is the opposite direction of the first direction;

[0099] When the preset vibration moment reaches the third moment node t3, generate a third angle adjustment instruction, where the third angle adjustment instruction is used to control the angle adjustment mechanism to stop moving;

[0100] Obtain the fourth vibration duration T4, and when the fourth vibration duration T4 reaches the fourth threshold, activate the angle adjustment mechanism to rotate the vibration assembly by the first preset angle in the second direction;

[0101] Obtain the fifth vibration duration T5, and when the fifth vibration duration T5 reaches the fifth threshold, control the vibration assembly to stop vibrating.

[0102] For ease of understanding, the following takes a specific usage scenario as an example to briefly describe the implementation process of the control method provided by the present invention.

[0103] First of all, in principle, the natural frequency of an object is its inherent characteristic. The vibration frequency of an object is the response vibration generated after being affected by a certain excitation source. The response frequency is related to the excitation frequency and can be higher or lower than the natural frequency. If it coincides with the natural frequency, resonance occurs. When the vibration frequency of an object is equal to its natural frequency, the amplitude of vibration will be amplified, which is resonance. Before application, the resonance frequency of the vibrating powder can be tested. In the actual application of vibration filling, the upper edge or lower edge frequency of the resonance frequency or a combined application can be used. The upper edge frequency is called high-frequency vibration, and the lower edge is called low-frequency vibration.

[0104] Therefore, during the process of material filling and inclination adjustment, as Figure 8 and Figure 9 shown, according to the size of the filling powder inlet and the fluidity of the powder, the time T0 for filling the first half of the powder can be tested. During application, first set the time T1 for vibrating and filling, and it is required that T1 > T0. When starting the vibrating and filling operation, when the vibrating time reaches T1, the cylinder for angle control is triggered to start. At this time, vibrating is accompanied by tilting, and the cylinder moves slowly. When tilting to half of the maximum angle, the cylinder stops moving after moving for t1, vibrates for T2, the cylinder continues to move to increase the tilting angle, stops moving after moving for t2, vibrates for T3, the cylinder moves in the reverse direction for t3, returns to half of the maximum angle, vibrates for T4, the cylinder continues to move for t4, and returns to the horizontal position, vibrating for T5. The above is a combined process of filling in an inclined vibrating mode, and the filling time is T = T1 + t1 + T2 + t2 + T3 + t3 + T4 + t4 + T5.

[0105] As Figure 10 shown, according to the state of the filled cavity, the above combined modes can be flexibly used: such as low-frequency inclined vibrating filling + high-frequency inclined vibrating filling, low-frequency inclined vibrating filling + high-frequency inclined vibrating filling + low-frequency inclined vibrating filling; high-frequency inclined vibrating filling + low-frequency inclined vibrating filling + high-frequency inclined vibrating filling, etc.

[0106] The vibration and dispersion mode of the vibration and dispersion plate can be set to low-frequency vibration and dispersion or high-frequency vibration and dispersion. Also, an appropriate vibration mode can be selected according to the characteristics of the product cavity. For example, there can be 12 filling modes including left, right, up, down, upper left, upper right, lower left, lower right, centered left and right, centered up and down, vibration and dispersion, and gathering.

[0107] In the above specific implementation manner, the mode control method provided by the present invention is used to adjust the vibration mode of the vibration and dispersion plate. The method generates a start command by obtaining the vibration duration of the vibration and dispersion plate and a preset vibration moment. When the vibration duration reaches the duration threshold, the start command is used to control the vibration component to start vibrating. When the vibration component starts vibrating and the preset vibration moment reaches the preset time node, an angle adjustment command is generated, and the angle adjustment command is used to control the angle adjustment mechanism to act according to a preset adjustment strategy. In this way, by adjusting the vibration mode and realizing angle adjustment at an appropriate vibration node, the unit density of the powder filling in the cavity can be effectively increased. Through vibration and swing, the filled powder can effectively fill all corners of the cavity, creating a volume for the final 1% filling to be quickly filled. This not only improves the filling efficiency but also ensures that the cavity can be filled solidly, improving the filling effect.

[0108] In addition to the above method, the present invention also provides a mode control device, as Figure 11 shown. The device includes:

[0109] A parameter acquisition unit 1101 for acquiring the vibration duration of the vibration and dispersion plate and a preset vibration moment;

[0110] A first command generation unit 1102 for generating a start command when the vibration duration reaches the duration threshold, and the start command is used to control the vibration component to start vibrating;
