Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of semiconductor packaging, and in particular to a fantasy light source packaging method, device and equipment based on dispensing parameter adjustment. BACKGROUND

[0002] The fantasy light source is a kind of light-emitting device capable of presenting a variety of color change effects, and is widely used in stage lighting, smart home, advertising signs and consumer electronics fields. In order to realize high brightness, multi-color, high consistency of light-emitting effect, the packaging quality of the fantasy light source has a direct impact on its light-emitting performance. Especially in the packaging process, as one of the key processes, dispensing needs to accurately control parameters such as glue amount, glue speed and glue path to ensure uniform glue layer, pad without shielding, consistent light, and avoid affecting the light-emitting efficiency and stability. Therefore, how to realize accurate dispensing control of different types of fantasy light sources has become an important research direction to improve product yield and performance.

[0003] At present, fixed dispensing parameters are mostly used in the packaging process of fantasy light sources for batch operation, and the dynamic adjustment of dispensing parameters still depends on manual experience judgment, which is difficult to accurately adapt to individual differences of different light source types. At the same time, in the existing packaging process, dispensing often lacks effective feedback mechanism for correcting dispensing process parameters, resulting in problems such as uneven brightness, wavelength shift or excessive leakage current in some packaged products; in addition, the setting of dispensing path and glue discharge height, speed and other parameters is mainly based on static configuration, which is difficult to intelligently optimize in combination with actual light-emitting performance, resulting in poor product consistency and difficult to guarantee yield. There are three key problems in the existing technology in dispensing control: first, there is a lack of comprehensive adaptation strategy for light source types and packaging structure, which cannot automatically generate effective dispensing path and parameters according to structure parameters; second, there is no closed-loop feedback between dispensing process and light-emitting performance test, which cannot dynamically adjust dispensing parameters based on test results; third, it is impossible to realize targeted optimization of light-emitting deviation of different color channels in the light path, resulting in that the packaging consistency and optical performance cannot meet the needs of high-end applications.

[0004] Therefore, how to improve the accuracy of dispensing control in the packaging process based on the structure characteristics of the light source and the feedback of the light-emitting performance is a problem to be solved. SUMMARY

[0013] Embodiment 1 Please refer to Figure 1 Embodiment 1 of the present application discloses a fantasy color light source packaging method based on dispensing parameter adjustment, which comprises the following steps: According to the light source type of the fantasy color light source to be packaged, the preset packaging size information, the preset pad size information and the preset pad layout information are determined. Specifically, first, according to the light source type of the fantasy color light source to be packaged, such as RGB three-in-one lamp beads, four-in-one lamp beads or high-density micro-LEDs, by calling the pre-constructed light source type database, the packaging structure characteristic parameters corresponding to the light source type are automatically matched, including the preset packaging size information, the preset pad size information and the preset pad layout information. The packaging structure characteristic parameters specifically include: the light source shape size (such as length, width and height), the packaging shell type (such as flip chip, SMD, COB, etc.), the geometric size of the pads (such as circular, rectangular and their specific values), the distance between the pads, and the specific layout mode of the pads on the substrate (such as linear arrangement, matrix arrangement or staggered arrangement). Through this process, structural basic data support is provided for the subsequent generation of dispensing path and dispensing amount allocation.

[0014] According to the preset packaging size information, the preset pad size information and the preset pad layout information, initial dispensing parameters corresponding to the fantasy light source type are obtained; Specifically, according to the preset packaging size information, the preset pad size information and the preset pad layout information determined in the previous step, initial dispensing parameters adapted to the structural characteristics of the fantasy light source are obtained. The packaging size information refers to the three-dimensional physical dimensions of the lamp bead body and its packaging shell, such as length, width and height, which determines the overall boundary of the dispensing area and the glue coverage range; the pad size information refers to the area, shape (such as circular, rectangular), boundary profile and the like of the metal pad, which directly affects the area that needs to be avoided by the glue and the dispensing precision that needs to be accurately positioned; the pad layout information refers to the arrangement form of the pads on the packaging bottom or substrate, such as linear, L-shaped, annular or matrix distribution, which affects the dispensing path planning and sequence control. Based on the above information, the initial dispensing path (for example: edge U-shaped distribution, central point distribution or matrix uniform distribution) and the dispensing amount parameter (such as the dispensing amount of each point, dispensing time, needle height, speed and the like) can be automatically generated. Through this process, the dispensing parameters under different light source structures can be quickly and intelligently matched, avoiding errors and repeated trial-and-error processes of manual parameter setting, improving the success rate and efficiency of the initial dispensing, and laying a foundation for subsequent closed-loop calibration and accurate control.

[0015] In an embodiment, referring to Figure 2 , the obtaining, according to the preset packaging size information, the preset pad size information and the preset pad layout information, of the initial dispensing parameters corresponding to the fantasy light source type comprises: According to the preset packaging size information, the preset pad size information and the preset pad layout information, the pad avoidance area and the non-pad avoidance area in the dispensing path are divided to obtain the dispensing effective area and the dispensing avoidance area; Specifically, according to the position, size and arrangement form of the pads in the packaging structure, the dispensing area is accurately classified to divide the pad avoidance area and the dispensing effective area; the pad avoidance area refers to an area that is not allowed to be dispensed, which is usually a metal pad for electrical connection and its surrounding safety buffer area to prevent the glue from covering the pad and affecting the welding or causing short circuit; and the dispensing effective area is the packaging space range that allows glue deposition, mainly concentrated in the non-conductive area between the pads and the packaging edge. For example, for an RGB lamp bead with a three-pad annular layout, the system will mark the central area and the rectangular area on the pad connection line as the avoidance area through coordinate calibration and packaging atlas analysis, and the remaining area as the effective area. This classification not only realizes high-precision avoidance control of dispensing operation, but also avoids glue pollution of the pads, improves the subsequent welding quality and stability of photoelectric performance, and is the basis for realizing a high-reliability packaging process.

[0016] According to the dispensing effective area and the dispensing avoidance area, a dispensing path is planned, and dispensing path coordinate information is obtained; Specifically, in the dispensing effective area, an optimized dispensing trajectory is generated according to the avoidance area contour and the package shape, and dispensing path coordinate information is output. The dispensing path coordinate information includes the accurate path nodes and sequence of the dispensing needle head moving in the X-Y plane, usually arranged in a curve, polyline or dot matrix to cover the entire effective area and ensure uniform dispensing; for example, in the case of avoiding three pads distributed in a "pin" shape, the path planning can adopt a surrounding U-shaped path or a peripheral circumferential path, and the start and stop point and turning point coordinates of each path segment are automatically planned. This path planning ensures complete coverage of the dispensing area and precise avoidance of the pad area, reduces errors and inconsistencies caused by manual path setting, and improves the efficiency of automated packaging, providing a standardized input basis for subsequent closed-loop control.

[0017] According to the package height parameter in the preset package size information, the vertical height of the dispensing is adjusted, and a dispensing height value is obtained; Specifically, the package height parameter usually refers to the thickness or height value of the light source shell or substrate, which is an important factor in determining the dispensing head drop distance and glue spraying precision. According to the package height parameter in the preset package size information, the appropriate height value between the dispensing head and the workpiece surface is automatically set, usually between 0.1mm and 0.5mm, to ensure accurate glue landing and natural glue forming. For example, for a 5050 LED lamp bead with a package height of 1.6mm, the needle height is set to 1.7mm, thereby realizing non-contact dispensing and avoiding needle collision with the surface of the component. Through height adjustment, dispensing precision can be significantly improved, preventing glue splashing or uneven accumulation, while ensuring the safety of the equipment operation and the consistency of the product, which is one of the key parameters for high-precision packaging control.

[0018] According to the dispensing path coordinate information and the dispensing height value, combined with the preset glue layer thickness and the preset glue dispensing speed of the dispensing equipment, the dispensing speed and the dispensing amount are calculated; Specifically, considering the dispensing path coordinate information, dispensing height value, preset glue layer thickness and preset dispensing speed of the dispensing equipment comprehensively, the optimal dispensing speed and dispensing amount parameters are calculated to realize the glue deposition effect with high precision and consistency. Among them, the dispensing path coordinate information determines the moving track and path length of the needle, the dispensing height value affects the drop point precision and diffusion radius of the glue deposition, and the preset glue layer thickness sets the glue coverage thickness according to the light source packaging demand, such as for moisture-proof, enhancing optical lens effect or fixing light source position. By inputting these parameters into the model and combining the glue discharge characteristics of the dispensing head, the matching needle moving speed (such as 3 mm / s) and glue discharge amount per unit time (such as 0.02 ml / s) are calculated. For example, for a 10 mm long path, the target glue layer thickness is 0.3 mm, and according to the dynamic matching of glue viscosity and equipment response characteristics, a reasonable moving speed and glue discharge rate are matched to ensure uniform glue distribution and avoid glue breakage or overflow. The introduction of this calculation step can greatly improve the dispensing precision and consistency, avoid the deviation caused by manual parameter adjustment, and realize adaptive dispensing control based on structure and process requirements.

[0019] In an embodiment, referring to Figure 3 , the calculating the dispensing speed and dispensing amount according to the dispensing path coordinate information and the dispensing height value, combining the preset glue layer thickness and the preset glue discharge speed comprises: calculating the total length of the dispensing path according to the dispensing path coordinate information to obtain the total length of the dispensing path; Specifically, by analyzing each trajectory point recorded in the dispensing path coordinate information, geometric algorithms (such as line segment distance accumulation or spline curve fitting) are used to calculate the length of the entire dispensing path to obtain the total length of the dispensing path. The dispensing path coordinate information is usually composed of multiple consecutive coordinate points, reflecting the moving track of the dispensing head in the X-Y plane; through this step, the path span of the entire packaging area is mastered, providing a basis for subsequent glue amount and speed calculation. For example, for complex packaging structures such as irregular annular or polygonal structure pad avoidance paths, accurate calculation of path length can avoid the problem of excessive or insufficient glue amount, thereby improving the uniformity of dispensing and packaging reliability.

[0020] calculating the dispensing volume required for unit path length according to the dispensing height value and the preset glue layer thickness to obtain the unit path glue amount; Specifically, the spatial volume is estimated by using the dispensing height value (referring to the vertical distance between the dispensing needle and the packaging surface) and the preset glue layer thickness (referring to the thickness covered by the target glue), so as to deduce the glue volume required per unit path length. The unit path glue amount is regarded as the glue output amount required per millimeter or per pixel on the path, which takes into account the expansion behavior on the packaging surface after the actual glue deposition; for example, a larger dispensing height may cause the glue diffusion area to become larger, which may correspondingly reduce the unit path glue output amount to prevent glue overflow. This calculation can make the dispensing more in line with the target thickness requirement, effectively ensuring the uniformity and consistency of the optical performance of the packaging glue layer.

[0021] According to the unit path glue amount and the total length of the dispensing path, the dispensing amount is calculated. Specifically, the unit path glue amount is multiplied by the total length of the dispensing path to obtain the total glue output amount required for the light source packaging task. The dispensing amount is the glue output amount target that the equipment needs to complete in the subsequent dispensing process, which directly affects the quantitative setting of the glue output control module. For example, for a longer path or a complex packaging structure, the dispensing amount will increase accordingly, and sufficient glue can be prepared in advance and the equipment glue output program can be optimized to avoid problems such as glue interruption, packaging loss, etc. due to insufficient glue amount. This step can significantly improve the utilization efficiency of glue and reduce material waste.

[0022] According to the unit path glue amount and the preset glue output speed, the moving speed of the dispensing head is calculated to obtain the dispensing speed.

[0023] Specifically, according to the unit path glue amount and the glue output speed supported by the equipment (i.e. the glue volume that can be output per second), the moving speed of the dispensing head is deduced. If the glue amount required per unit path is large and the glue output speed is limited, the moving speed of the dispensing head will be slowed down to ensure that the glue covers sufficiently; otherwise, the speed can be appropriately increased to improve efficiency. For example, the precise white light packaging area requires a higher glue thickness, so the moving speed should be lower to ensure uniform deposition. By dynamically adjusting the dispensing speed, real-time matching of the glue output amount and the path travel is realized, which significantly improves the packaging consistency and the yield of finished products.

[0024] According to the dispensing path coordinate information, the dispensing speed, the dispensing height value and the dispensing amount, the initial dispensing parameters are determined.

[0025] Specifically, according to the four core parameters of dispensing path coordinate information, dispensing speed, dispensing height value and dispensing amount, the entire dispensing process is preliminarily modeled, and then the initial dispensing parameters are determined. These initial dispensing parameters include key execution instructions such as dispensing head moving trajectory, moving speed, glue dispensing rhythm and height control strategy. The dispensing path coordinate information defines the movement route of the dispensing head in three-dimensional space; the dispensing speed ensures that the glue dispensing rhythm is synchronized with the path progress; the dispensing height value controls the gap between the needle and the packaging surface, thereby affecting the precision of glue deposition; and the dispensing amount is the total material distribution target to be achieved by the glue dispensing system. Taking the packaging of RGB three-color color-changing LED as an example, different color blocks may differ in path, thickness and optical requirements, so through this multi-parameter fusion modeling, the differentiated setting of dispensing strategies for different regions can be realized, thereby improving the precision and adaptability of the initial dispensing scheme, and laying a foundation for subsequent closed-loop parameter adjustment and light emitting performance feedback optimization.

[0026] According to the initial dispensing parameters, the color-changing light source is subjected to initial dispensing processing and die bonding, and the color-changing light source after die bonding is subjected to light emitting performance detection to obtain detection values of preset light emitting parameters; Specifically, first, according to the initial dispensing parameters, the color-changing light source is subjected to dispensing processing, and the packaging glue is accurately deposited to the specified effective area to meet the requirements of structure fixation and optical control; after dispensing is completed, the die bonding stage is entered, and the glue is cured through heating or ultraviolet curing, thereby ensuring stable connection between the chip and the packaging structure, and providing a reliable basis for subsequent performance detection. After the glue curing is completed, the color-changing light source after die bonding is subjected to light emitting performance detection to obtain detection values of key optical parameters such as brightness, color coordinates and luminous flux of the color-changing light source under preset driving conditions such as current and voltage. Through this process, the effective connection from dispensing to detection is realized, which provides a basis for subsequent parameter optimization and improves the packaging consistency and light emitting quality.

[0027] In an embodiment, referring to Figure 4 , the initial dispensing processing and die bonding of the color-changing light source according to the initial dispensing parameters, and the light emitting performance detection of the color-changing light source after die bonding to obtain detection values of preset light emitting parameters include: obtaining preset forward driving current values and reverse bias voltage values; Specifically, the standard electrical driving conditions matched with the type of the color-changing light source are extracted from a preset database or an experience parameter library, including forward driving current values and reverse bias voltage values. The forward driving current value is the current size required by the light source when it is working normally, which is used to excite the LED or other light emitting unit to generate light; the reverse bias voltage value is the voltage applied when testing its reverse electrical characteristics, which is used to evaluate the reverse leakage of the device. By obtaining these standard test electrical conditions, the consistency and comparability of subsequent detection can be ensured, which is helpful to establish a unified evaluation standard.

[0028] The forward driving current value is taken as a test condition to obtain a forward voltage detection value, a luminous brightness detection value, and a luminous detection wavelength of the target power supply; Specifically, the forward driving current is applied to the encapsulated fantasy color light source to simulate its actual working state. Under this driving condition, the forward voltage value (i.e., voltage drop when turned on), luminous brightness (unit: cd or lm, reflecting light output intensity), and luminous wavelength (representing color characteristics) exhibited by the target light source are collected by a test device. For example, for an RGB fantasy color LED, the main emission wavelengths and their corresponding brightness of the red, green, and blue channels can be measured respectively. This process can realize accurate evaluation of key performances such as photoelectric conversion efficiency and color shift.

[0029] The reverse bias voltage value is taken as a test condition to obtain a reverse leakage current detection value of the target power supply; Specifically, under the condition of no light output, a reverse bias voltage is applied to the target light source to evaluate its reverse conduction performance, i.e., the leakage current of the device in a non-working state. In an ideal state, the LED and other light sources should have almost no current passing through under reverse bias voltage, so the level of the leakage current value directly reflects the electrical integrity and insulation quality of the chip and the package. If an abnormally high leakage current is detected, it may indicate that the chip has defects, the dispensing is improper, or the package is short-circuited, which helps to identify potential failure risks as soon as possible.

[0030] According to the forward voltage detection value, the luminous brightness detection value, the luminous detection wavelength, and the reverse leakage current detection value, a detection value of the preset luminous parameter is determined.

[0031] Specifically, the above four key test indicators are summarized to form the luminous performance detection value of the current sample, and are compared with the preset target value. These detection values not only cover electrical characteristics (such as forward voltage and reverse leakage current), but also cover optical performance (such as brightness and luminous wavelength), which can comprehensively reflect the influence of dispensing and die bonding quality on the luminous effect. Through this comprehensive evaluation, the system can judge whether the current packaging parameters meet the standards, provide quantitative basis for subsequent dispensing parameter optimization or abnormal analysis, and thus realize precise closed-loop control based on performance feedback.

[0032] According to the deviation value between the detection value and the target value of the preset luminous parameter, the initial dispensing parameter is adjusted to obtain a target dispensing parameter; Specifically, the detected light-emitting performance parameters (such as forward voltage, brightness, wavelength, leakage current) are compared with the preset target performance parameters, and the deviation value between the two is calculated. If the deviation exceeds the acceptable range, the system will analyze the corresponding dispensing problem (such as insufficient dispensing amount leading to reduced brightness, uneven glue layer leading to wavelength shift, etc.) according to the deviation type and trend, and automatically adjust the initial dispensing parameters (such as modifying the dispensing speed, glue amount, path coverage area, etc.) to generate more optimized target dispensing parameters. This adjustment mechanism based on performance feedback can improve the adaptability and accuracy of dispensing, and realize dynamic optimization of light source packaging performance.

[0033] In an embodiment, referring to Figure 5 Before the adjustment of the initial dispensing parameters according to the deviation value between the detection value and the preset value to obtain the target dispensing parameters, it further includes: According to the light source type of the color-changing light source, the target value of the preset light-emitting parameter is obtained, wherein the target value includes the forward voltage target value, the light-emitting brightness target value, the light-emitting target wavelength, and the reverse leakage current target value. Specifically, first, identify the type of the color-changing light source being processed, such as RGB packaged LED, white LED, or multi-chip integrated LED, etc. Different types of light sources have different internal chip structures, electrode layouts, and material properties, and their target light-emitting performance parameters also differ. Retrieve the ideal light-emitting performance indicators corresponding to this light source type from the database as the target value, including: forward voltage target value (representing the voltage that the chip should exhibit under forward driving), light-emitting brightness target value (indicating the light intensity under normal driving), light-emitting target wavelength (indicating the main wavelength value that the color output should reach), and reverse leakage current target value (representing the minimum leakage behavior it should have under reverse bias). This step provides a benchmark for subsequent error judgment and dispensing parameter adjustment.

[0034] According to the forward voltage target value and the forward voltage detection value, a forward voltage deviation value is calculated; Specifically, by comparing the forward voltage detection value obtained after packaging testing with the target voltage value of this light source type, the voltage deviation is obtained. For example, if the target voltage is a certain value, and the actual detection value is higher, it may mean that the dispensing thickness is too large, there are problems such as electrode connection defects or increased thermal resistance, etc. This deviation value is an important indicator for evaluating the consistency of electrical performance, and can be used to judge the matching degree of the packaging process.

[0035] According to the light-emitting brightness target value and the light-emitting brightness detection value, a light-emitting brightness deviation value is calculated; Specifically, by comparing the target luminance with the measured luminance, the difference is calculated. For example, if the measured luminance is lower, it may be due to uneven dispensing, glue blocking, insufficient die bonding accuracy, or impurities in the package. This deviation value helps to determine whether the dispensing coverage is appropriate and whether it affects the light energy output, thereby providing feedback for adjusting the glue amount, path density, or thickness, effectively improving product consistency and yield.

[0036] According to the light-emitting target wavelength and the light-emitting detection wavelength, a light-emitting deviation wavelength is calculated; Specifically, by comparing the target wavelength with the actually detected main light-emitting wavelength, a wavelength deviation value is obtained. For example, the target main wavelength of a blue light LED may be a certain nanometer value, while the measured wavelength is longer or shorter, reflecting the interference of glue material on the spectrum, chip position error, or scattering problems of the light channel during packaging. This deviation value can be used as a basis for adjusting the dispensing path optimization (such as avoiding key light paths), glue selection (such as low absorption materials), etc.

[0037] According to the reverse leakage current target value and the reverse leakage current detection value, a reverse leakage current deviation value is calculated; Specifically, by comparing the target reverse leakage current value (generally lower) with the measured value, the electrical insulation performance after packaging is determined. If the measured leakage current is much higher than the target, it may indicate glue leakage, lead short circuit, or contamination problems during dispensing. This deviation value can guide the system to detect whether the dispensing is out of bounds, whether the glue amount is too much and causes abnormal connection of the conductive path, and helps to improve the electrical reliability of the overall device.

[0038] According to the forward voltage deviation value, the light-emitting luminance deviation value, the light-emitting deviation wavelength, and the reverse leakage current deviation value, the deviation value is determined.

[0039] Specifically, the above four types of deviation data are aggregated and analyzed, which can use a weighted model or a rule matching model to quantitatively evaluate the overall deviation degree. This deviation value can be understood as the degree of deviation of the overall light-emitting performance from the expected target, which is used to drive the adaptive optimization and adjustment of the dispensing parameters. Through this closed-loop evaluation mechanism, the system can accurately identify the key factors affecting the packaging quality and improve the precision and product consistency of automatic packaging.

[0040] In an embodiment, the adjustment of the initial dispensing parameters according to the deviation value between the detection value and the target value of the preset light-emitting parameter includes: The forward voltage deviation value, the light-emitting luminance deviation value, and the light-emitting deviation wavelength are classified respectively to determine the deviation value corresponding to each light channel respectively; Specifically, in the color-changing light source, usually contains multiple light channels (such as R, G, B channels), each channel represents the light emitted by different color chips. Therefore, each channel is analyzed independently. The overall deviation data obtained previously is classified by channel and attributed to the corresponding red, green and blue light channels respectively to determine the deviation values of each light channel respectively. For example, the voltage deviation value, brightness deviation value and wavelength deviation value of the red light channel will be managed separately from the green and blue light channels. This classification processing method facilitates the system to accurately identify the specific light-emitting state of each sub-channel, and helps to analyze and optimize the dispensing quality or position consistency of each chip.

[0041] Obtain the preset forward voltage tolerance interval, light-emitting brightness tolerance interval and light-emitting wavelength tolerance interval corresponding to each light channel, and obtain the preset maximum reverse leakage current value; Specifically, the performance tolerance interval set for different light channels is extracted from the database, that is, the allowed deviation range of voltage, brightness and wavelength of each channel. For example, the brightness of the red light channel may be allowed to fluctuate within a small range, while the wavelength deviation cannot exceed a certain nanometer range. At the same time, the maximum allowable value of the reverse leakage current applicable to the entire device is also extracted. The purpose of obtaining these tolerance ranges is to establish a set of objective detection standards, so that the judgment process has clear basis and facilitates automated screening.

[0042] Select any target light channel in each light channel. If the forward voltage deviation value corresponding to the target light channel is not within the forward voltage tolerance interval corresponding to the target light channel, and / or the light-emitting brightness deviation value corresponding to the target light channel is not within the light-emitting brightness tolerance interval corresponding to the target light channel, and / or the light-emitting deviation wavelength corresponding to the target light channel is not within the light-emitting wavelength tolerance interval corresponding to the target light channel, and / or the reverse leakage current deviation value is greater than the maximum reverse leakage current value, then it is identified as abnormal light emission; Specifically, the detection value of each light channel is compared with the corresponding preset tolerance interval one by one to determine whether there is an abnormality. If the forward voltage deviation value corresponding to any target light channel in each light channel is not within the forward voltage tolerance interval corresponding to the target light channel, and / or the light-emitting brightness deviation value corresponding to the target light channel is not within the light-emitting brightness tolerance interval corresponding to the target light channel, and / or the light-emitting deviation wavelength corresponding to the target light channel is not within the light-emitting wavelength tolerance interval corresponding to the target light channel, and / or the reverse leakage current deviation value is greater than the maximum reverse leakage current value, then it is considered that the light-emitting performance of the channel is abnormal. For example, although the brightness of the blue light channel is normal, its wavelength deviation is too far, which may cause visual color difference; or although the wavelengths of the three channels are normal, the overall leakage current is too large, which may also affect the stability. By comparing and checking each item one by one, the abnormality recognition has high precision and high robustness.

[0043] adjust the initial dispensing parameters to obtain target dispensing parameters when the light-emitting abnormality is identified.

[0044] Specifically, once the light-emitting abnormality is found, the adjustment mechanism of dispensing parameters is triggered. The adjustment is based on the deviation trend presented by the abnormal channel, such as the fact that a certain channel wavelength is generally longer, which means that the dispensing thickness or position is too thick or deviated; or the fact that the brightness is too low, which means that too much light-blocking glue or bubbles interfere with the light-emitting channel. Through the attribution analysis of these deviation types, the dispensing path coordinates, dispensing speed, dispensing height and other parameters are reset to achieve a dispensing effect closer to the target value in subsequent production. This process establishes a closed-loop mechanism of detection-feedback-correction, which helps to improve product consistency and stability of light-emitting quality.

[0045] In an embodiment, referring to Figure 6 , the adjusting the initial dispensing parameters to obtain target dispensing parameters when the light-emitting abnormality is identified comprises: if the forward voltage deviation value corresponding to the target light channel is not within the forward voltage tolerance interval corresponding to the target light channel, then the dispensing height value is reduced to obtain a target dispensing height value; Specifically, the deviation of the forward voltage is often related to the heat conduction or electrical conduction environment between the chip and the glue. When the dispensing height is high, the glue forms a thicker isolation layer between the chip and the support, which may affect the heat dissipation efficiency of the chip during the power-on process and the formation of the current path, thereby causing the forward voltage to rise or deviate. By reducing the dispensing height value, that is, making the dispensing head closer to the substrate, the glue layer thickness can be thinned while maintaining the coverage of the glue, thereby improving the heat conduction and electrical connection between the chip and the packaging structure, and finally achieving fine control of the voltage deviation. This method does not need to change the materials or the structure on a large scale, but only needs to adjust the process parameters to achieve rapid response and compensation, thereby improving the flexibility of the production line.

[0046] if the light-emitting brightness deviation value corresponding to the target light channel is not within the light-emitting brightness tolerance interval corresponding to the target light channel, then the dispensing amount is increased to obtain a target dispensing amount value; Specifically, if the light-emitting brightness deviation value corresponding to the target light channel is not within the light-emitting brightness tolerance interval corresponding to the target light channel, one of the common reasons is that the coverage is uneven or the glue thickness is insufficient during the dispensing process, which reduces the diffuse reflection effect of light in the packaging glue, thereby reducing the overall light-emitting efficiency. By moderately increasing the dispensing amount, the uniformity and integrity of the glue above the chip can be improved, forming a more ideal optical packaging environment. Good filling of the glue can enhance the light shaping ability in the chip light-emitting path, improve the light concentration and transmittance, and thus improve the brightness. In addition, in a multi-chip array, appropriately increasing the dispensing amount can also help to offset the small mounting height error and improve the light-emitting consistency. This strategy optimizes the optical performance through quantity control, which has the advantages of high compatibility and low intervention.

[0047] If the light-emitting deviation wavelength corresponding to the target light channel is not within the light-emitting wavelength tolerance interval corresponding to the target light channel and / or the reverse leakage current deviation value is greater than the preset maximum reverse leakage current value, the dispensing path coordinate information is adjusted to obtain target dispensing path coordinate information. Specifically, the deviation of the light-emitting wavelength is often related to the stress on the chip, uneven heat dissipation, or the distribution of the optical properties of the glue. If the light-emitting deviation wavelength corresponding to the target light channel is not within the light-emitting wavelength tolerance interval corresponding to the target light channel and / or the reverse leakage current deviation value is greater than the preset maximum reverse leakage current value, the high reverse leakage current may be caused by the stress on the chip edge, short-circuit hazards caused by dispensing deviation, or electrical pollution. Such problems require more in-depth dispensing position adjustment. By optimizing the dispensing path coordinate information, such as adjusting the starting or ending coordinates, optimizing the relative position of the glue line and the chip center, or appropriately bypassing the edge of the key light-emitting area, the glue distribution area can be accurately controlled, thereby reducing stress concentration, improving packaging consistency, and improving the electrical insulation of the device. Such coordinate-level fine-tuning scheme has very high controllability and can be finely adapted to different chip layouts and sizes to improve overall product yield.

[0048] If the light-emitting brightness deviation value corresponding to the target light channel is not within the light-emitting brightness tolerance interval corresponding to the target light channel, the dispensing speed is adjusted to obtain a target dispensing speed. Specifically, the abnormality of light-emitting brightness usually reflects problems of light extraction efficiency or packaging uniformity. In the dispensing process, dispensing speed is one of the key factors affecting the uniformity of glue deposition and the actual glue distribution. If the dispensing speed is too fast, it may cause glue tailing, incomplete coverage, or thin thickness, thereby affecting the light refraction path and reducing the light-emitting brightness. On the contrary, slow speed may cause local glue accumulation, leading to abnormal optical scattering. Therefore, when the brightness deviation exceeds the tolerance interval, fine adjustment of the dispensing speed can indirectly control the unit path glue distribution state, achieve more uniform and reasonable optical packaging effect, and thus calibrate the brightness deviation. This strategy does not involve replacing materials or devices and only requires software-level adjustment in the dispensing process parameters, with the advantages of fast response and strong adaptability.

[0049] According to the target dispensing path coordinate information, the target dispensing speed, the target dispensing height value, and the target dispensing amount, a target dispensing parameter is determined.

[0050] Specifically, after adjusting a single parameter (such as speed), it is still necessary to re-integrate all process parameters related to dispensing of the light channel to form a set of dispensing setting values that are coordinated and have high matching, i.e. target dispensing parameters. These parameters are interdependent: path coordinate information determines the position and shape of the glue distribution, dispensing height affects the accuracy of the glue drop and thickness control, dispensing speed determines the glue output rhythm per unit time, and dispensing amount determines the volume of the encapsulated glue. Therefore, a set of balanced parameters needs to be fitted again under new process conditions to ensure that the glue can cover the effective area and guarantee the stability and consistency of the light emitting performance in actual application. Through this step of parameter integration, the chain deviation caused by adjusting a single parameter can be effectively avoided, and the overall process can be re-optimized.

[0051] In an embodiment, the determining the target dispensing parameters according to the target dispensing path coordinate information, target dispensing speed, target dispensing height value and target dispensing amount comprises: According to the target dispensing path coordinate information, target dispensing speed, target dispensing height value and target dispensing amount, dispensing processing and die bonding are performed on the Fantasia light source to determine the encapsulated Fantasia light source; Specifically, first, the dispensing operation is performed based on the obtained target dispensing path coordinate information, target dispensing speed, target dispensing height value and target dispensing amount. The dispensing path coordinate information refers to the accurate position sequence of the nozzle moving on the substrate during dispensing, which determines the distribution trajectory of the glue in space; the dispensing speed refers to the rate of the nozzle moving along the path, which affects the continuity and density of the glue deposition; the dispensing height value is the vertical distance between the nozzle and the target base surface, which directly affects the drop shape and diffusion area of the glue drop; the dispensing amount is the output volume of the glue per unit time, which determines the material coverage thickness in the dispensing area. The fantasy light source usually refers to a LED light source with multi-channel light emitting capability, which can present dynamic or gradient color, such as RGB three-color chip or RGBW four-color combination chip, etc. After the fantasy light source is dispensed according to the target dispensing path coordinate information, target dispensing speed, target dispensing height value and target dispensing amount, the purpose is to accurately apply glue to the target area and complete die bonding (i.e. fixing the LED chip on the substrate) under the premise of ensuring the qualified light emitting performance (such as forward voltage, wavelength, etc.), so as to realize preliminary packaging. This is the basic link for subsequent light efficiency detection and optimization; before dispensing, the coordinate system on the target substrate usually needs to be recognized through a visual positioning system, then the nozzle is controlled to move in three dimensions according to the predetermined path and accurately apply glue; after dispensing is completed, the die bonding link is entered, which can be completed through hot pressing, cold pressing or ultraviolet curing to fix the chip and solidify the glue. Through this step, it can ensure that the initial packaging quality of the fantasy light source is high and the parameter consistency is good, which provides a reliable basis for subsequent light efficiency detection, and also avoids problems such as chip offset, color difference or brightness abnormality caused by uneven glue application, improves the overall yield and stability.

[0052] According to the light source type of the packaged fantasy light source, the preset light efficiency requirement parameter corresponding to the light source type is determined; Specifically, the light source type is divided according to the structure and functional characteristics of the fantasy light source, including: Figure 7The three-channel breakpoint resume 5V series shown, the first light-emitting chip 1 is a chip inside the device for emitting light, emitting light of a specific wavelength (such as red, green or infrared light), for optical detection, communication or lighting functions; The first metal electrode pad 2 is a metal pad connected to the first light-emitting chip 1, which is used to transmit external electrical signals to the chip, provide power or control signals, and at the same time play a supporting role for the chip and electrical connection. The first soldering point 3 is the position of the electrode of the first light-emitting chip welded to the electrode pad through a metal lead (such as gold wire or aluminum wire), realizing the electrical connection between the chip and the packaged circuit; The first bottom soldering leg 4 is a metal lead-out end at the bottom of the device, which is used to transmit the electrical signal of the first light-emitting chip to the external circuit board (such as PCB), and is connected to the mainboard through reflow soldering; The photosensitive sensor 5 is a device that receives light signals, which can sense ambient light or reflected light, etc., for building closed-loop feedback control, detecting user status or identifying the surrounding environment; As Figure 8 The four-channel 5V series shown, the second light-emitting chip 6 can emit light of different wavebands (such as red, green, white, infrared), for realizing multi-waveband measurement, or enhancing detection accuracy; The second soldering point 7 is used to connect the metal lead soldering point between the second light-emitting chip and its electrode pad, realizing stable electrical path; The second bottom soldering leg 8 is used to connect the second light-emitting chip signal to the external metal soldering leg, ensuring that the working voltage and signal output of the second chip can be normally conducted; And as Figure 9The third metal electrode pad 9 is a metal surface for connecting the second light emitting chip, and forms a connection point with an external circuit to provide power supply and control signal interface for the chip. The third light emitting chip 10 is a chip inside the device for emitting light, emitting light of a specific wavelength (such as red, green or infrared), for optical detection, communication or lighting function. The third soldering point 11 is a lead soldering point for connecting the third light emitting chip and its metal electrode pad, ensuring stable operation of the chip and maintaining the integrity of the electrical path. The packaging shell 12 is the external structural part of the entire device, used for mechanical protection of the internal chip, lead and electrode, with certain optical transparency, thermal conductivity and structural stability. The third bottom lead foot 13 provides electrical connection for the third light emitting chip, and is soldered to the main circuit board through the patch technology, realizing signal transmission and power supply between the chip and the main board. Different types of color-changing light sources have significant differences in light emission mode, control method and expected effect. The three-channel break-point continuation 12V color-changing series refers to each light source module having three independent control channels (RGB) of red, green and blue, which can realize multi-color light emission effect, and uses 12V direct current power supply. The break-point continuation function of this series can ensure that the subsequent light beads can still receive signals and operate normally in the case of damage or communication interruption of a certain light bead, effectively improving the system stability. Since 12V voltage has strong pressure drop resistance, it is particularly suitable for large-scale lighting engineering, outdoor lighting projects or advertising signs and other scenes that require longer wiring distance. The three-channel break-point continuation 5V series is similar in function and structure to the 12V series, with red, green and blue color control channels and break-point continuation capability, which can realize rich color changes and good fault tolerance performance. However, it uses 5V low voltage power supply, which is safer and more compact in circuit design, suitable for short wiring environment. Due to its low power consumption and easy-to-drive characteristics, this type of light source is commonly used in indoor intelligent lighting systems, wearable devices, DIY lighting projects and other small or delicate application scenarios. The four-channel 5V series adds a white light channel (W) based on the traditional RGB three-channel, forming an RGBW structure, which can provide more realistic and soft white light performance while maintaining color-changing dynamic effect. This four-channel configuration not only enhances the color mixing precision, but also meets the needs of occasions with higher requirements for natural light effect. This series also uses 5V low voltage power supply, which is more suitable for delicate and safe electronic environments, and is commonly used in film and television lighting settings, indoor high-end decoration, music atmosphere lamps and other scenes that require both white and colored light. Light effect requirement parameters refer to the requirements for the final light effect performance, including target light intensity, target color temperature and target light emission angle.First, the light source type of the finished encapsulated fantasy light source is obtained, for example, the product code of the encapsulated fantasy light source is read; then the light source type is determined according to the read product code, and the pre-set light effect demand template in the pre-collected light effect template parameter database is matched according to the light source type to determine the light effect demand parameter corresponding to the light source type, and the light effect template parameter database can be derived from experience data, user feedback, or lighting industry standards, etc.

[0053] The finished encapsulated fantasy light source is subjected to light effect detection to obtain light effect detection parameters; Specifically, the light effect detection refers to the process of objective quantitative analysis of the visual light emitting effect of the finished encapsulated fantasy light source in the lighting state. When the finished encapsulated fantasy light source is subjected to light effect detection, a multi-point detection method based on a photosensitive resistor or a photodiode module is adopted to obtain key light effect detection parameters, and the specific method includes: lighting the finished encapsulated fantasy light source under the condition of a standard constant current, and arranging multiple photosensitive devices at calibrated positions in front of and at different angles of the finished encapsulated fantasy light source for collecting light intensity values in different directions to calculate the actual light emitting intensity and the actual light emitting angle distribution information; at the same time, by arranging photosensitive elements responding to different wavelengths at these detection points, the actual color temperature of the light source is calculated, and the actual light emitting intensity, the actual light emitting angle distribution information and the actual color temperature are taken as the light effect detection parameters. This scheme can quickly output the light effect detection parameters to provide basic data support for subsequent light effect optimization and ensure that the fantasy light source reaches the expected visual effect of the user in terms of brightness, color and light emitting angle.

[0054] According to the light effect demand parameter and the light effect detection parameter, a light effect deviation parameter is calculated; Specifically, after obtaining the light efficiency requirement parameters and the light efficiency detection parameters, the two are compared and analyzed item by item, so as to calculate the light efficiency deviation parameters, which are used to quantify the difference between the light efficiency performance of the current fantasy light source and the target requirement. Specifically, first, the detection parameters and their corresponding target values are standardized, for example, the luminous intensity is uniformly converted into unit light intensity, the color temperature is uniformly converted into Kelvin unit, and the luminous angle is converted into a group of angle-light intensity pair distribution functions; then, the error analysis method is used to calculate the deviation value: the luminous intensity deviation is represented by the difference or percentage error between the actual luminous intensity and the target luminous intensity; the color temperature deviation is measured by the color temperature drift value or the color difference index; the luminous angle deviation can be obtained by integrating the difference of the angle-light intensity distribution to obtain the angle deviation score, or extracting the key indicators such as the offset of the main light emission direction and the edge attenuation trend. In order to improve the comprehensive judgment of the overall light efficiency deviation degree, the three types of deviations can be respectively assigned weights, and a comprehensive deviation score value is calculated, for example, using weighted average deviation or a normalized score model; the final light efficiency deviation parameter will form a set of clear numerical set, which can be used to judge whether the current light source meets the product standard or user demand, and can also be used as the basis for point glue process optimization or personalized correction, supporting subsequent automatic adjustment of point glue parameters according to different light source types, so as to continuously improve the consistency, aesthetics and user visual experience of the light source without increasing the hardware complexity.

[0055] According to the light efficiency deviation parameter and the preset light efficiency deviation threshold, it is judged whether the target point glue path coordinate information, the target point glue speed, the target point glue height value and the target point glue amount need to be fine-tuned and optimized; Specifically, after obtaining the light efficiency deviation parameter, it is compared with the preset light efficiency deviation threshold to judge whether the packaged fantasy light source has significant deviation, and whether the target point glue path coordinate information, the target point glue speed, the target point glue height value and the target point glue amount need to be fine-tuned and optimized. Specifically, first, call the deviation threshold template matched with the current light source type, which sets the acceptable error range of different light efficiency dimensions based on product standards, user experience requirements or historical process experience, for example: the brightness deviation is not more than ±10%, the color temperature deviation is not more than ±300K, and the luminous angle deviation is not more than ±5 degrees. Then, compare the current light efficiency deviation parameter with these thresholds item by item, if any item exceeds the tolerance range, it is determined that the light source packaging effect is not up to standard, and the fine-tuning mechanism is triggered.

[0056] If the target point glue path coordinate information, the target point glue speed, the target point glue height value and the target point glue amount need to be fine-tuned and optimized, the light efficiency deviation type is determined according to the light efficiency deviation parameter; Specifically, if fine-tuning optimization of the target dispensing path coordinate information, target dispensing speed, target dispensing height value and target dispensing amount is required, under the premise of determining that fine-tuning optimization of the dispensing parameters is required, the light efficiency deviation is first classified in order to formulate an optimization strategy accordingly; the light efficiency deviation data is converted into identifiable light efficiency deviation types, the light efficiency deviation types including brightness deviation, color temperature deviation, and light emitting angle deviation, each type of deviation reflecting specific problems that may exist in the packaging process; based on the comparison difference between the obtained light efficiency detection parameters and the preset target value, the numerical deviation is extracted and classified according to the dimension. For example: if the actual brightness is significantly lower than the target brightness (such as a deviation of more than ±10%), it is identified as a brightness deviation type; if the detected color temperature deviates from the target value by a large margin (such as a deviation of more than ±300K to the cold or warm side), it is classified as a color temperature deviation type; if the brightness distribution in different directions detected by the photosensitive device is abnormal, the light emitting angle deviates from the target or the phenomenon of too narrow / too wide occurs, it is determined as a light emitting angle deviation type. In addition, composite deviation types can also be identified by analyzing multi-dimensional deviation combinations, for example: low brightness + narrow light emitting angle, which may be due to insufficient glue layer coverage or insufficient packaging glue height, etc. After classification is completed, the deviation type is transmitted as input to the subsequent optimization decision module to realize the linkage logic of the dispensing parameter correction strategy corresponding to the deviation type. Such a structure not only improves the pertinence of system response, but also makes the process adjustment more precise and efficient.

[0057] According to the light efficiency deviation type, fine-tuning optimization is performed on the target dispensing path coordinate information, target dispensing speed, target dispensing height value and target dispensing amount, and the dispensing path information, dispensing speed, dispensing height value and dispensing amount after optimization are taken as the target dispensing parameters; Specifically, after the light efficiency deviation type is determined, the dispensing process parameters are fine-tuned and optimized accordingly based on the light efficiency deviation type to reduce the key process errors of the final light efficiency performance. Specifically, if it is identified as a brightness deviation type (such as low brightness), the light source packaging is insufficient due to insufficient dispensing height or too little dispensing amount, which is compensated by moderately increasing the target dispensing height value and / or the target dispensing amount; if it is a color temperature deviation type (such as cold or warm), the dispensing path coordinate information and the dispensing speed are fine-tuned to ensure consistent light refraction of chips of different colors, thereby improving the color mixing effect, due to uneven packaging thickness of chips of different colors and deviation of the packaging glue penetration path. All adjustments use fine-grained change values to ensure micro-correction without affecting the overall structure. Finally, the fine-tuned and optimized dispensing path, dispensing speed, dispensing height and dispensing amount are output as new target dispensing parameters and applied to the next round of packaging operation to realize closed-loop self-optimization control and significantly improve the consistency and light output quality of the product.

[0058] In an embodiment, the target dispensing path coordinate information, the target dispensing speed, the target dispensing height value and the target dispensing amount are fine-tuned and optimized according to the light effect deviation type, and the dispensing path information, the dispensing speed, the dispensing height value and the dispensing amount after the optimization are included as the target dispensing parameters. If the light effect deviation type is the brightness deviation type, the actual brightness value and the brightness demand value are obtained according to the light effect demand parameter and the light effect detection parameter. Specifically, if the light effect deviation type is the brightness deviation type, the current actual brightness value and the brightness demand value are obtained according to the light effect demand parameter and the light effect detection parameter. The actual brightness value and the brightness demand value together constitute the basic data for evaluating the light effect deviation, both of which are expressed in a unified brightness unit and are ensured to be completely aligned in spatial position between the detection area and the demand area, so as to ensure the consistency and comparability of the data.

[0059] According to the actual brightness value and the brightness demand value, the brightness deviation value between the actual brightness and the expected brightness demand is calculated. Specifically, the actual brightness value and the corresponding brightness demand value are calculated by difference to obtain the brightness deviation value; the deviation value is represented as ΔL = L_actual - L_target, where L_actual is the actual brightness and L_target is the brightness demand value. In order to improve the sensitivity and stability of the adjustment, the brightness deviation value can be further normalized or a weighting factor can be introduced to reflect the sensitivity of the human eye to different brightness changes.

[0060] According to the brightness deviation value, the brightness deviation is divided into a mild deviation interval and a severe deviation interval in combination with a preset first brightness deviation threshold and a second brightness deviation threshold, wherein the first brightness deviation threshold is less than the second brightness deviation threshold. Specifically, in order to realize the differentiated adjustment of different brightness deviation situations, two preset brightness deviation thresholds, i.e., a first brightness deviation threshold L_th1 and a second brightness deviation threshold L_th2, are obtained, wherein L_th1 < L_th2. When L_th1 < |ΔL| ≤ L_th2, it is determined as mild brightness deviation; and when |ΔL| > L_th2, it belongs to severe brightness deviation. The classification provides a basis for hierarchical execution of the control strategy, ensuring that the adjustment under different deviation levels is targeted, energy-saving and stable.

[0061] If it is divided into the mild deviation interval, the dispensing adjustment amount is calculated according to a preset linear function model and the brightness deviation value. Specifically, when the luminance deviation value is in the slight deviation interval, a preset linear function model is called to respond to the adjustment of the deviation; the linear function model takes the luminance deviation value as an input variable and outputs a dispensing adjustment amount ΔQ, which represents the amount of glue that should be increased or decreased; for example, , wherein is a linear adjustment coefficient. The linear function model can be obtained through empirical data or pre-training and is suitable for small adjustment scenarios to achieve optimized control with low energy consumption and high response.

[0062] According to the dispensing adjustment amount, the target dispensing amount and the target dispensing height value are adjusted to determine the fine-tuned and optimized dispensing amount and the fine-tuned and optimized dispensing height value, wherein the dispensing height and the dispensing amount maintain a fixed proportional relationship; Specifically, after the linear function model calculates the dispensing adjustment amount ΔQ, the current target dispensing amount Q is added to ΔQ to obtain the fine-tuned and optimized dispensing amount Q′. At the same time, the dispensing height H and the dispensing amount Q have a fixed proportional relationship (such as H = αQ, wherein α is a preset proportional constant), and the target dispensing height value is updated synchronously to H′ = αQ′. This strategy of maintaining a proportional relationship between the height and the amount of glue can avoid glue overflow or uneven glue coating caused by uncoordinated dispensing height and ensure stable and reliable adjustment process.

[0063] If it is divided into the severe deviation interval, the target dispensing amount is supplemented non-linearly according to an exponential function model, and the target dispensing height value is adjusted non-linearly synchronously according to the dispensing amount change value to determine the fine-tuned and optimized dispensing amount and the fine-tuned and optimized dispensing height value; Specifically, if the luminance deviation value exceeds the second luminance deviation threshold (i.e., ΔL > L_th2), the dispensing amount is non-linearly supplemented and adjusted by calling an exponential function model; the exponential function form is as follows , wherein A is a reference increment, and β is an exponential adjustment coefficient. This model can more effectively deal with large luminance deficiency and achieve rapid compensation. After the dispensing amount change value ΔQ is calculated, the dispensing height is adjusted accordingly based on the non-linear relationship function H = β√Q between the dispensing amount and the height, and is updated to This non-linear adjustment mechanism makes the glue coverage more accurately match the actual light-emitting demand area, avoiding local excessive glue coating that causes color spots or halos.

[0064] If the light efficiency deviation type is a color temperature deviation type, then according to the light efficiency demand parameter and the light efficiency detection parameter, a color temperature difference value between an actual color temperature value and a color temperature demand value is obtained; ​Specifically, if the light efficiency deviation type is a color temperature deviation type, first, according to the light efficiency requirement parameter and the light efficiency detection parameter, an actual color temperature value (T_actual) and a corresponding target color temperature requirement value (T_target) are extracted, a color temperature deviation value ΔT is obtained through a difference calculation formula ΔT=T_actual-T_target, and the color temperature difference value directly reflects the degree of deviation of the current color temperature from the target. This step provides a basic quantitative basis for the subsequent color temperature correction strategy and is the first link to achieve accurate adjustment.

[0065] According to the color temperature difference value, the color temperature deviation direction is determined. Specifically, after obtaining the color temperature difference value ΔT, the sign and the value range thereof are further identified to determine the deviation direction and the deviation level. If ΔT>0, it is determined that the color temperature deviation is in the cold direction, that is, the cold color component is too much. If ΔT < 0, it is determined that the color temperature deviation is in the warm direction, that is, the warm color component is too much. This step ensures that the adjustment not only has directionality but also has grading control capability to prevent over-adjustment or insufficient adjustment.

[0066] When the color temperature deviation direction is the cold direction, the target dispensing path coordinate information is offset to the warm color chip region according to a path offset distance to obtain fine-tuned and optimized dispensing path coordinate information, wherein the path offset distance is calculated based on the color temperature difference value and a preset proportion coefficient. Specifically, when it is determined that the deviation direction is the cold direction, that is, ΔT is positive, the target dispensing path coordinate information is adjusted to deviate to the warm color chip region. The specific operation is as follows: a path offset distance d_offset =k_path×ΔT is calculated according to the product of ΔT and a preset proportion coefficient k_path, and then the current target path coordinate point (x, y) is translated to a new coordinate point (x', y'), wherein (x', y')=(x+dx, y+dy), and (dx, dy) is the offset direction quantity towards the warm color chip region. This strategy realizes the increase of the proportion of the warm light chip in light emission through physical position adjustment, thereby effectively neutralizing the cold light color temperature and achieving the purpose of color temperature balance.

[0067] When the color temperature deviation direction is the warm direction, the target dispensing path coordinate information is offset to the cold color chip region according to the path offset distance to obtain fine-tuned and optimized dispensing path coordinate information. Specifically, when the color temperature deviation direction is the warm direction, that is, ΔT is negative, it indicates that the current light-emitting area is insufficient in cold color component; similarly, according to |ΔT| and a preset proportion coefficient k_path, the offset distance d_offset=k_path×|ΔT| is calculated, but this time the offset direction is towards the cold color chip area, and the coordinate point is updated as (x', y')=(x+dx, y+dy), dx and dy correspond to the offset direction amount of the cold color area. This path coordinate fine-tuning makes more cold color glue be applied to the light-emitting area, effectively enhancing the cold color light output, so as to realize overall color temperature recall.

[0068] According to the fine-tuned and optimized dispensing path coordinate information, the target dispensing height value is adjusted synchronously to determine the fine-tuned and optimized dispensing height value, wherein the synchronous adjustment of the dispensing height adjustment value is positively correlated with the path offset distance, and a path-height coupling function is formed; Specifically, after obtaining the fine-tuned and optimized dispensing path coordinate information, the target dispensing height value (H_target) is further adjusted synchronously according to the path offset distance (d_offset). Since the path offset means that the spatial structure of the dispensing target area has changed slightly (such as moving from the chip edge to the center or moving from the cold-warm junction to a specific color gamut), the dispensing height needs to be adjusted synchronously to ensure that the dispensing thickness is uniform and the light efficiency is consistent. Therefore, a path-height coupling function H_adj=H_target+k_h×d_offset is constructed, wherein k_h is a height adjustment proportion coefficient. This model realizes the dynamic cooperation of path change and height change, avoiding new deviations in color temperature or brightness caused by height mismatch.

[0069] According to the dispensing path offset distance and the dispensing height adjustment value, a dispensing area change rate is calculated; Specifically, when the dispensing path is offset and the height is changed, the effective area of the dispensing area may also change, thereby affecting the glue distribution density and the light color output characteristics. Through the formula S_ratio=(S_new−S_origin) / S_origin, the dispensing area change rate (S_ratio) caused by the path offset and the height linkage adjustment is calculated. Wherein, S_origin is the original dispensing area, S_new is the adjusted dispensing area, and the dispensing area is calculated from the dispensing path offset distance and the dispensing height adjustment value. This change rate serves as a key indicator for judging whether subsequent speed linkage adjustment is needed, which helps to prevent problems such as excessive coverage or dispensing sparseness.

[0070] When the area change rate is greater than a preset area change rate threshold, according to the area change rate, a dispensing speed adjustment amount is determined, wherein the dispensing speed adjustment amount is negatively correlated with the area change rate; Specifically, when the area change rate S_ratio exceeds a pre-set area change rate threshold S_th, it indicates that the geometric characteristics of the dispensing area have changed significantly. At this time, the dispensing speed adjustment amount is calculated by a negative correlation model V_adj = V_target x (1-k_v x S_ratio), where V_target is the target dispensing speed, and k_v is the speed adjustment proportion coefficient. This strategy is based on the principle that the dispensing area needs to be slowed down when it expands, and the dispensing area can be moderately accelerated when it shrinks, ensuring that the deposition density of the dispensing glue per unit time remains stable, and avoiding uneven light performance caused by movement path adjustment.

[0071] According to the dispensing speed adjustment amount, the target dispensing speed is adjusted to obtain a fine-tuned and optimized dispensing speed.

[0072] Specifically, finally, based on the dispensing speed adjustment amount calculated above, the current target dispensing speed is updated synchronously to obtain the fine-tuned and optimized dispensing speed V_opt. This step ensures that the path, dispensing height, and speed form a closed-loop adjustment, so that the continuity, uniformity, and control accuracy of light output during color temperature correction are comprehensively improved. The entire control process can be embedded in the dispensing control module in real time, and combined with the online light efficiency detection system to form a closed-loop feedback adjustment system, ensuring product consistency.

[0073] If the target dispensing path coordinate information, target dispensing speed, target dispensing height value, and target dispensing amount do not need to be optimized, the target dispensing path coordinate information, target dispensing speed, target dispensing height value, and target dispensing amount are taken as the target dispensing parameters.

[0074] According to the target dispensing parameters, a light source of the same type as the fantasy light source is dispensed and die-bonded to complete the packaging process of the fantasy light source.

[0075] Specifically, after the target dispensing parameters are set, they can be applied to the mass production process of the same batch or the same type of fantasy light source product. Since the process conditions of the light source chip in the manufacturing process are basically the same, the structural parameters and optoelectronic characteristics of the same model product are also basically the same, so the target dispensing parameters have good replicability and generalization ability. When dispensing is implemented, using the target dispensing parameters can significantly improve the packaging consistency, avoid the random occurrence of problems such as brightness, color difference, and current abnormality, and thus improve the light performance yield of the entire batch of products. In addition, the target dispensing parameters can also be used as an experience template in the process database to provide a quick initialization scheme for subsequent other batches or similar models, shorten the debugging period, and improve production efficiency.

The device introduces a structure parameter recognition and parameter matching mechanism based on the light source type, first automatically determines the packaging size, pad size and pad layout information corresponding to the fantasy light source to be packaged according to the type of the fantasy light source to be packaged, and then acquires the adaptive initial dispensing parameters to realize accurate matching of dispensing control and light source structure. Subsequently, the light emitting performance of the light source after initial dispensing is detected, the detection values of key light emitting parameters such as forward voltage, luminous brightness, wavelength and reverse leakage current are collected, and the detection values are compared with the preset target values to obtain the performance deviation information of each light channel. The dispensing parameters are dynamically adjusted based on the deviation result to form a closed-loop control process of structure parameter driving-dispensing execution-performance detection-parameter feedback-optimization adjustment, and finally the fine control of the fantasy light source dispensing process and the consistency guarantee of the light emitting performance are realized, and the accuracy of dispensing control in the packaging process is improved.
