[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] like Figure 1 As shown, an embodiment of the present application provides a method for automatically adjusting the amount of glue in a glue dispensing machine, including a glue dispensing machine, wherein the glue dispensing machine includes a glue dispensing valve 1 and a weighing mechanism 2, and the automatic adjustment of the glue amount of the glue dispensing valve 1 includes the following steps:

[0039] S100: Set the standard glue weight G0 of dispensing valve 1 and calibrate weighing mechanism 2;

[0040] S200: The time from dispensing valve 1 dispensing glue to weighing mechanism 2 is recorded as the actual dispensing time T, and weighing mechanism 2 records the glue weight G;

[0041] S300: Compare the recorded glue weight G with the standard glue weight G0. If G=G0, enter the production mode; otherwise, enter the dispensing parameter calculation mode.

[0042] The dispensing parameter calculation steps include:

[0043] S301: deriving a dispensing parameter T0 according to the actual dispensing time T, the standard glue weight G0 and the recorded glue weight G;

[0044] S302: The precision balance is automatically reset;

[0045] S303: Using the dispensing parameter T0 to control the dispensing time, dispensing the glue, and recording the actual dispensing time T and glue weight G;

[0046] S304: Execute step S300.

[0047] Specifically, the watch shell is assembled on the watch body through the steps of dispensing, assembly, and pressure holding. After dispensing, the integrity and position of the glue path are inspected by the visual inspection mechanism 5. After the watch shell is assembled on the watch body, the visual inspection mechanism 5 is used to inspect whether there is excess glue overflowing from the edge of the product. If the inspection meets the requirements, the airtightness of the product is inspected by the airtightness inspection mechanism to prevent the situation where the amount of glue is small and the airtightness is insufficient. If the inspection result does not meet the requirements, the amount of glue in the dispensing valve 1 needs to be adjusted. In order to meet the requirements of product production quality, it is necessary to automatically adjust the amount of glue discharged by the dispensing valve 1 at regular intervals.

[0048] The motion control module 4 drives the dispensing valve 1 to move to the glue weighing station. The dispensing valve 1 is located above the weighing mechanism 2. The time from the first dispensing of the dispensing valve 1 to the weighing mechanism 2 is recorded as the dispensing time T1. The weighing mechanism 2 records the first glue weight G1. The first glue weight G1 is compared with the standard glue weight G0. If G1=G0, the production mode is entered. Otherwise, the dispensing parameter calculation is entered. The dispensing parameter calculation formula is T0=T1×G0÷G1. The control software uses the dispensing parameter TO to control the dispensing time of the dispensing valve 1, and performs the second dispensing. The second dispensing time T2 and the second glue weight G2 are recorded. The second glue weight G2 is compared with the standard glue weight G0. If G2=G0, the production mode is entered. Otherwise, the dispensing parameter calculation is entered. The dispensing parameter calculation formula is T0=T2×G0÷G2. The control software uses the dispensing parameter T0 to control the dispensing time of the dispensing valve 1, and performs the third dispensing. The third dispensing time T3 and the third weighing weight G3 are recorded. The third weighing weight G3 is compared with the standard glue weight G0. If G2=G0, the production mode is entered. Otherwise, the alarm prompts to enter the manual mode. Among them, the actual dispensing time T is the time from the dispensing valve 1 to the beginning of dispensing to the weighing mechanism 2 to the end of dispensing. The dispensing parameter T0 is the dispensing time of the dispensing valve 1 controlled by the system.

[0049] In the above structure, the dispensing parameter T0 is calculated according to the actual dispensing time T, the standard glue weight G0 and the glue weight G, and the system automatically controls the dispensing time and speed according to the dispensing parameter T0, thereby achieving high-precision adjustment of the glue amount G. This adjustment method is not only simple and convenient, but also fast in adjustment speed, saving labor and time costs, and improving the automation capability of the equipment and the yield rate of the product.

[0050] like Figure 1 As shown, in one embodiment, the dispensing parameter T0 calculation formula of the method for automatically adjusting the glue amount of the dispensing machine is: T0 = T × G0 ÷ G. Through the linear adjustment relationship between the dispensing time T and the standard glue weight G0 and the recorded glue weight G, a new dispensing parameter T0 is obtained, and the dispensing time is controlled by the new dispensing parameter T0, so as to obtain the glue amount G that meets the requirements. This calculation method is simple and convenient, and there is no need to adjust various aspects of the system parameters.

[0051] like Figure 1 As shown, in one embodiment, step S304 of the method for automatically adjusting the glue amount of the glue dispenser further includes accumulating three cycles, and if the standard glue weight condition is not met, an alarm is issued to prompt the manual mode. After three rounds of automatic adjustment, if the standard glue weight condition is still not met, the system alarms and the equipment is manually tested to ensure the normal operation of the equipment.

[0052] like Figure 1As shown, in one embodiment, the method step S100 of automatically adjusting the glue amount of the glue dispenser further includes the following steps:

[0053] S101: A glue weighing container is placed on the weighing mechanism 2, and the weight of the glue weighing container is reset. A glue weighing container is placed on the weighing mechanism 2, and the glue dispensing valve 1 dispenses glue on the glue weighing container. The weighing mechanism 2 weighs the glue amount on the glue container. The weighing mechanism 2 is a precision balance. The use of the weighing mechanism 2 improves the accuracy of the glue amount detection, and the use of the glue weighing container improves the cleanliness when weighing the glue.

[0054] like Figure 2 As shown, in one embodiment, the method step S100 of automatically adjusting the glue amount of the glue dispenser further includes the following steps:

[0055] S102: Setting the glue weighing rhythm, wherein the glue weighing rhythm is the time setting for the glue dispensing valve 1 to enter the glue weighing mode;

[0056] S103: Check the glue weighing rhythm condition, and enter the glue weighing step S200 if it meets the glue weighing rhythm. The glue weighing rhythm time can be set according to user needs. The glue weighing rhythm time can be set to 30 minutes. The dispensing machine is in production mode. When the glue weighing rhythm time is less than 30 minutes, the dispensing valve 1 continues the dispensing operation; when the glue weighing rhythm time is greater than 30 minutes, the dispensing valve 1 enters the glue weighing mode after completing the dispensing work. This operation is convenient for users to set the rhythm of automatically adjusting the glue amount according to their needs to ensure production quality.

[0057] Preferred embodiment:

[0058] S100: Set the standard glue weight G0 of dispensing valve 1 and calibrate weighing mechanism 2;

[0059] S101: placing a weighing container on the weighing mechanism 2, and performing a zeroing operation on the weight of the weighing container;

[0060] S102: Setting the weighing rhythm;

[0061] S103: Detect the glue weighing rhythm condition, and if the glue weighing rhythm is met, enter the glue weighing step S200;

[0062] S200: The time from dispensing valve 1 dispensing glue to weighing mechanism 2 is recorded as the actual dispensing time T, and weighing mechanism 2 records the glue weight G;

[0063] S300: Compare the recorded glue weight G with the standard glue weight G0. If G=G0, enter the production mode. Otherwise, enter the calculation of the glue dispensing parameter T0.

[0064] The calculation steps of dispensing parameter T0 include:

[0065] S301: deriving the dispensing parameter T0 according to the actual dispensing time T, the standard glue weight G0 and the recorded glue weight G. The dispensing parameter T0 is calculated by the formula: T0 = T × G0 ÷ G;

[0066] S302: The precision balance is automatically reset;

[0067] S303: Using the dispensing parameter T0 to control the dispensing time, dispensing the glue, and recording the actual dispensing time T and glue weight G;

[0068] S304: Execute step S300 for a total of three cycles. If the standard glue weight condition is not met, an alarm is triggered to prompt the user to enter manual mode.

[0069] Specifically, first set the standard glue weight G0 (minimum value - maximum value) and the glue weighing cycle. The glue weighing cycle time can be set to 30 minutes. When the glue dispensing work of the glue dispenser is completed and meets 30 minutes, which meets the glue weighing cycle time, the glue dispenser enters the glue weighing mode.

[0070] After entering the glue weighing mode, the motion control module 4 drives the glue dispensing machine to perform the glue weighing station. The time from the first glue discharge from the glue dispensing valve 1 to the glue weighing container of the weighing mechanism 2 is recorded as the glue discharge time T1. The weighing mechanism 2 records the first glue weight G1. The first glue weight G1 is compared with the standard glue weight G0. If G1=G0, the glue dispensing machine enters the production mode. Otherwise, the automatic glue dispensing parameter T0 calculation is entered. The calculation formula of the glue dispensing parameter T0 is T0=T1×G0÷G1.

[0071] The dispensing parameter TO is used to control the dispensing time, and the second dispensing is performed. The second dispensing time T2 and the second glue weight G2 are recorded. The second glue weight G2 is compared with the standard glue weight G0. If G2=G0, the dispensing machine production mode is entered. Otherwise, the automatic dispensing parameter calculation is entered. The dispensing parameter calculation formula is T0=T2×G0÷G2.

[0072] The dispensing parameter T0 is used to control the dispensing time, and the third dispensing is performed. The third dispensing time T3 and the third weighing weight G3 are recorded. The third weighing weight G3 is compared with the standard glue weight G0. If G3=G0, the dispensing machine enters the production mode, otherwise, an alarm prompts to enter the manual mode.

[0073] In the above structure, the dispensing parameter T0 is calculated according to the actual dispensing time T, the standard glue weight G0 and the glue weight G, and the dispensing time and speed are controlled by the dispensing parameter T0, so as to control the dispensing amount of glue with high precision. The method of automatic adjustment of the glue amount of the dispensing machine is not only simple and fast, but also realizes automatic dispensing adjustment, improves the adjustment efficiency, and greatly saves labor and time costs.

The motion control module 4 drives the dispensing valve 1 to enter the production mode, so that the dispensing valve 1 performs dispensing processing on the product along the dispensing path. The motion control module 4 can also drive the dispensing valve 1 to enter the weighing mode, so that the dispensing valve 1 discharges glue to the weighing mechanism 2 for weighing operation. This setting facilitates driving the dispensing valve 1 to perform dispensing and weighing operations, and improves the movement efficiency of the dispensing valve 1.

The first linear module 41 and the second linear module 42 cooperate with each other to realize the glue dispensing movement of the glue dispensing valve 1 along the Y-axis and Z-axis directions, thereby improving the movement efficiency of the glue dispensing valve 1 in all directions.

[0076] like Figure 3 As shown, in one embodiment, the automatic glue quantity adjustment system of the glue dispenser also includes an industrial computer, and the industrial computer is provided with control software for running the adjustment system.
