[0002] At present, in the mobile phone camera industry and other electronic semiconductor industries, in order to pursue lightweight and stable products, it is necessary to fix the lens assembly to the voice coil motor during the assembly process of the camera module. Although the lens and the voice coil motor are assembled and fixed with threads, the gap between the two needs to be reinforced with glue to improve the stability of the entire camera module. Therefore, the adjacent structural parts of the lens and the voice coil motor are fixed with glue.

[0003] The working principle of the dispensing equipment used in the camera module is to use air pressure to press the glue in the needle tube out, and cooperate with the movement of the placement platform below to draw a line of glue on the surface of the bonded parts. However, there are often bubbles in the glue in the needle tube, which often causes the glue line to be disconnected during the glue application, affecting the dispensing quality, thereby affecting the bonding quality of the adjacent structural parts of the lens and the voice coil motor, and even causing the quality of the entire camera module product to be abnormal.

[0043] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0044] The present invention provides a method for improving the quality of dispensing glue, such as Figure 1 As shown, the method comprises the following steps:

[0045] Step S110, creating a dispensing simulation model; bubbles of a preset size exist in the dispensing simulation model.

[0046] In one embodiment, creating a dispensing simulation model includes:

[0047] Create a 3D fluid model with bubbles, glue and air of preset sizes;

[0048] Based on the relative positions of the 3D needle assembly, the 3D valve assembly, the 3D placement platform assembly and the 3D fluid model, the 3D needle assembly, the 3D valve assembly, the 3D placement platform assembly and the 3D fluid model are combined to obtain the dispensing simulation model.

[0049] Specifically, before creating the dispensing simulation model, the present invention needs to first create a 3D model of the dispensing device based on a 3D modeling software, such as Figure 2 As shown, the 3D model of the glue dispensing equipment includes: a 3D needle tube assembly 21, a 3D needle head assembly 22 and a 3D placement platform assembly 23, the 3D needle head assembly 22 is connected and located below the 3D needle tube assembly 21, and is used for drawing glue; a glue assembly 24 is placed in the 3D needle tube assembly 21 and the 3D needle head assembly 22, wherein the glue dispensing position of the 3D needle head assembly 22 is located at the connection position between the lens of the camera module and the voice coil motor.

[0050] It should be noted that after the 3D model of the dispensing equipment is created, the coordinates of each component in the 3D model are fixed, and the relative positional relationship between the components is also fixed.

[0051] Generally speaking, if there are bubbles inside the glue, the bubbles will eventually reach the needle assembly 22 over time. Therefore, when analyzing the effect of bubbles on the dispensing quality, the present invention only needs to analyze the bubbles in the needle assembly 22, and then the 3D model of the dispensing equipment needs to be simplified. Figure 3 As shown, the present invention can retain the 3D needle assembly 22 and the 3D placement platform assembly 23, and add a 3D valve assembly 25 on the upper part of the 3D needle assembly 22, and the 3D valve assembly 25 is used to provide dispensing pressure.

[0052] Then, a 3D fluid model is created to simulate the scene where there are bubbles in the glue. The 3D fluid model contains bubbles, glue and air of preset sizes.

[0053] In one embodiment, creating a 3D fluid model includes:

[0054] Add an air domain component to the periphery of the glue component, and use Boolean operations to combine the air domain component and the glue component into a geometric body;

[0055] Meshing the geometric body to obtain glue mesh cells and air mesh cells;

[0056] Based on the preset bubble size and bubble position, a corresponding number of glue grid cells at the corresponding position are set as air grid cells to form a 3D fluid model.

[0057] Specifically, in the actual dispensing scene, the glue is fluid and will flow around. In the 3D modeling software, such as Figure 4 As shown, the newly imported glue component 24 can be received in a new modeling interface, such as Figure 5 As shown, an air domain component 42 is added to the periphery of the glue component 24, and the glue component 24 and the air domain component 42 are combined by Boolean operation, and finally as shown in Figure 5 As shown, a 3D fluid model is formed. Among them, Boolean operation refers to the operation of generating new geometric features or geometric bodies by adding, subtracting or intersecting two or more geometric bodies in geometric modeling features. The glue component represents the glue in the real dispensing device, and the air domain component represents the air in the real dispensing device.

[0058] from Figure 5 It can be seen that the 3D fluid model is actually a geometric body. In order to clearly distinguish the glue and air domains in the 3D fluid model, each component in the 3D fluid model needs to be defined. For example, in the property interface of the simulation software, the required components can be added or deleted according to the needs. Therefore, component 1 and component 2 can be added in the property interface of the simulation software. Component 1 can be set as the glue component of the 3D fluid model, and component 2 can be set as the air domain component in the 3D fluid model.

[0059] Then import this geometry into the meshing software and use the meshing software to mesh the geometry. The meshed 3D fluid model is as follows: Figure 6 shown.

[0060] In this way, after the geometry is meshed, the reference Figure 7 , a glue grid unit 71 and an air grid unit 72 can be obtained.

[0061] Then, based on the received component movement command, the glue grid unit 61 is removed, which is equivalent to the presence of bubbles in the original continuous glue. Figure 7 As shown in the mark 73 in.

[0062] The size of the bubble can be determined based on the number of removed glue grid units 61. The more removed glue grid units 61 are, the larger the bubble size is. Generally speaking, the bubble size can be set to 0.5 to 0.9 mm. Of course, the bubble size can also be set based on the actual glue dispensing equipment, which is not limited here.

[0063] As described above, after the 3D fluid model is created, bubbles, glue and air of preset sizes are set in the 3D fluid model.

[0064] Then the 3D needle assembly 22, the 3D placement platform assembly 23, the 3D valve assembly 25 and the 3D fluid model are imported into the simulation platform, and based on the relative positions of the 3D needle assembly 22, the 3D valve assembly 25, the 3D placement platform assembly 23 and the 3D fluid model, they are combined to obtain a dispensing simulation model.

[0065] It can be understood that in the simplified 3D model, the relative positions among the 3D needle assembly 22, the 3D valve assembly 25, and the 3D placement platform assembly 23 are fixed. Therefore, after being imported into the simulation platform, the positional relationship among the 3D needle assembly 22, the 3D valve assembly 25, and the 3D placement platform assembly 23 will not change.

[0066] Similarly, since the relative position relationship between the 3D needle assembly 22 and the glue assembly 24 is also fixed, the relative position between the glue assembly 24 and the air domain assembly 42 is also fixed, after the 3D needle assembly 22, the 3D valve assembly 25, the 3D placement platform assembly 23 and the 3D fluid model are imported into the simulation platform, each component can be combined in sequence based on its relative position with other components to form a dispensing simulation model.

[0067] Among them, the dispensing simulation model can be Figure 8 shown.

[0068] Step S111, obtaining each group of simulation parameters, simulating the dispensing simulation model under each group of simulation parameters, and outputting corresponding simulation results; the simulation parameters include: dispensing pressure and glue flow speed.

[0069] After the dispensing simulation model is determined, the dispensing simulation model can be simulated under each set of simulation parameters.

[0070] However, it should be noted that before the simulation, before simulating the dispensing simulation model under each set of simulation parameters, the method further includes:

[0071] Get the material type, material parameters, and simulation type of each component of the dispensing simulation model, and set simulation constraints.

[0072] Specifically, during the simulation process, different materials need to be set to different types. Since both air and glue can flow, the present invention sets the material type to "Euler body".

[0073] Similarly, the material parameters corresponding to different components are also different. For the 3D needle assembly (hereinafter referred to as the needle assembly), the 3D placement platform assembly (hereinafter referred to as the placement platform assembly) and the 3D valve assembly (hereinafter referred to as the valve assembly), the material parameters include: density, Young's modulus and Poisson's ratio. Among them, the material parameters of the 3D needle assembly 22, the 3D placement platform assembly 23 and the 3D valve assembly 25 are shown in Table 1:

[0074] Table 1

[0075]

[0076] The material parameters of the 3D glue component 24 (referred to as glue component) are shown in Table 2:

[0077] Table 2

[0078]

[0079] Among them, EOS refers to the parameter value specified by the equation of state, which is the speed at which sound propagates in the glue, in m / s.

[0080] After the material parameters are set, the simulation type needs to be set. The glue path is drawn using a dispensing device, which belongs to dynamic analysis. Therefore, the present invention will determine the simulation type as the "display dynamic analysis" type.

[0081] It is understandable that if there are no corresponding constraints on the placement platform, the glue will penetrate the placement platform during the downward flow. Therefore, after the simulation type is set, it is also necessary to set corresponding constraints for the glue dispensing simulation model. The constraint is "general contact", which is mainly used to prevent the glue from penetrating the placement platform when it flows downward. Under the action of the constraints, the glue will remain on the placement platform after flowing to the placement platform, and then effective simulation can be performed.

[0082] After the above simulation conditions are determined and set, each set of simulation parameters can be obtained and the fluid can be redefined. The dispensing simulation model is simulated under each set of simulation parameters to output the corresponding simulation results; the simulation parameters include: dispensing pressure and glue flow speed.

[0083] Specifically, the dispensing pressure can be achieved by applying pressure to the valve assembly, and the glue flow rate can be achieved by applying speed or displacement to the needle assembly.

[0084] In the present invention, multiple groups of simulation parameters may be preset, and the simulation parameters may be determined based on empirical parameters of an actual dispensing process, which is not limited herein.

[0085] Under each set of simulation parameters, the dispensing simulation model is simulated to obtain the corresponding simulation results, where the simulation results are the dispensing results.

[0086] Step S112, determining target simulation parameters from the groups of simulation parameters based on the simulation results, and dispensing the components to be bonded using the target simulation parameters as actual dispensing parameters; the simulation results corresponding to the target simulation parameters are results that meet the dispensing quality requirements.

[0087] In one embodiment, determining target simulation parameters from each group of simulation parameters based on the simulation results includes:

[0088] For any simulation result, it is determined whether there is glue break in the simulation result. If it is determined that there is no glue break, the corresponding simulation parameter is determined as the target simulation parameter.

[0089] Alternatively, the target simulation parameters are determined from each set of simulation parameters based on the simulation results, including:

[0090] For any simulation result, determine whether there is glue breakage in the simulation result;

[0091] If it is determined that there is glue breakage, it is further determined whether the current glue length is less than the preset glue breakage length threshold. If it is determined that the current glue breakage length is less than the glue breakage length threshold, the corresponding simulation parameter is determined as the target parameter.

[0092] Specifically, since each set of simulation parameters corresponds to a set of simulation results, if the simulation results meet the requirements of dispensing quality, it means that this set of simulation parameters is appropriate; if the simulation results do not meet the requirements of dispensing quality, it means that the corresponding simulation parameters are inappropriate. Therefore, the present invention can screen out target simulation parameters that meet the dispensing quality according to the simulation results.

[0093] In practical applications, when dispensing glue, a continuous glue path is a relatively ideal situation. Therefore, when there is no glue break in the simulation results, the corresponding simulation parameters can be used as target simulation parameters.

[0094] Of course, if glue breakage occurs, but the length of the break is short and will not affect the actual bonding quality, this situation also meets the requirements of glue dispensing quality.

[0095] Therefore, if the glue cut length is less than the glue cut length threshold, the corresponding simulation parameter can also be determined as the target parameter. The glue cut length can be set according to actual conditions, for example, it can be 0.5-0.8 mm.

[0096] In this way, by creating a dispensing simulation model, defining bubbles of preset sizes in the simulation model, and then simulating the dispensing simulation model to determine the target simulation parameters, during actual dispensing, even if there are bubbles in the glue in the syringe, appropriate actual dispensing parameters can be set according to the simulation results to ensure the quality of dispensing, thereby improving the bonding quality of adjacent structural parts of the camera module and improving the overall quality of the camera module product.

[0097] Based on the same inventive concept as in the above-mentioned embodiment, this embodiment also provides a device for improving the dispensing quality, such as Fig. 9 As shown, the device comprises:

[0098] A creation unit 91 is used to create a dispensing simulation model; there are bubbles of a preset size in the dispensing simulation model;

[0099] The simulation unit 92 is used to obtain each set of simulation parameters, simulate the dispensing simulation model under each set of simulation parameters, and output corresponding simulation results; the simulation parameters include: dispensing pressure and glue flow speed;

[0100] The determination unit 93 is used to determine the target simulation parameters from the groups of simulation parameters based on the simulation results, and to perform glue dispensing on the components to be bonded using the target simulation parameters as actual glue dispensing parameters; the simulation results corresponding to the target simulation parameters are results that meet the glue dispensing quality requirements.

[0102] Creating a 3D fluid model, wherein bubbles, glue, and air of preset sizes exist in the 3D fluid model;

[0103] The dispensing simulation model is obtained by combining the position coordinates of the 3D needle model, the 3D valve model, the 3D placement platform model and the 3D fluid model.
