[0003] During the dispensing process, several identical workpieces on the dispensing machine will be dispensed with glue one by one. However, due to the errors of the workpieces themselves, the depth of the dispensing grooves of several identical workpieces may be different. Figure 1 As shown, there are certain differences in the amount of glue used during dispensing. Before the existing dispensing operation, the depth of each workpiece dispensing groove is measured by laser height measurement, and the glue output of the dispensing valve is manually adjusted according to the measured depth of the dispensing groove to ensure that the amount of glue in the dispensing groove can meet the process requirements. The operation is complicated and the manual operation precision is low. Moreover, during dispensing, the long-term use of the dispensing valve will leave a certain amount of glue in the valve, the amount of glue output of the dispensing valve will increase, and the dispensing precision will decrease accordingly, reducing the yield rate of the workpiece. Generally, the dispensing precision is improved by manually discharging glue, cleaning the valve, and then re-adjusting the valve parameters, but the dispensing efficiency is slow.

[0060] Embodiment 1: This embodiment of the present application provides a method for compensating for glue distribution, such as Figure 2 As shown, the method comprises the following steps:

[0061] S1, set the working parameters of the dispensing valve, which include: channel number of the dispensing valve, working mode, fixed dispensing parameters and adjustable dispensing parameters, see Figure 3 shown.

[0062] S2, obtaining the standard glue height of the workpiece, and setting the valve parameters of multiple channel numbers of the dispensing valve based on the working parameters and the standard glue height. The valve parameters of each channel number include multiple glue height intervals and the glue output Wn corresponding to the glue height intervals.

[0063] S3, obtaining the actual height of the workpiece dispensing slot and the current number of dispensing times; for example, obtaining the actual height of the workpiece dispensing slot through a distance measuring sensor; counting each dispensing through a counter to calculate the number of dispensing times. Distance measuring sensors include but are not limited to laser rangefinders or radar distance sensors.

[0064] S4, comparing the actual height of the workpiece dispensing groove with multiple glue height intervals, obtaining the glue height interval where the actual height of the workpiece dispensing groove is located, obtaining the corresponding channel number according to the current glue height interval, switching the channel number of the dispensing valve, obtaining the glue output Wn corresponding to the glue height interval, and determining whether to perform glue amount distribution compensation according to the current number of dispensing times;

[0065] If the current number of dispensing times is within the preset value, the dispensing valve is controlled to dispense glue to the dispensing groove of the workpiece based on the glue output Wn corresponding to the glue height interval;

[0066] If the current dispensing times are not within the preset value, weigh the single dispensing amount of the dispensing valve to obtain the single dispensing amount value W 单 , when the glue output Wn corresponding to the glue height range remains unchanged, based on the fixed glue dispensing parameters, according to the single glue dispensing value W 单 Adjust the dispensing adjustable parameters, and control the dispensing valve to dispense glue to the workpiece dispensing groove according to the adjusted dispensing adjustable parameters and the glue output Wn corresponding to the glue height range.

[0067] In practical applications, the shapes of the dispensing grooves include but are not limited to square, U-shaped and V-shaped.

[0068] In this embodiment, see Figure 4 As shown, step S2 specifically includes the following steps:

[0069] Get the standard glue height and get the standard total glue volume W 总 .

[0070] Based on the fixed dispensing parameters and the adjustable dispensing parameters, the standard dispensing frequency P0 of the dispensing valve is obtained, where the fixed dispensing parameters include the valve opening time T K , Rise time T S , Delay time T D And the fall time T X , the dispensing adjustable parameters include compensation delay time T D', in actual application, the delay time will be relatively small at the initial setting to facilitate glue volume distribution compensation and achieve normal dispensing operation. Furthermore, the standard dispensing frequency P0 of the dispensing valve is calculated as follows: P0=1000 / T, T is the dispensing time, T=T K +T S +T D +T X .

[0071] According to the preset number of dispensing points N of the dispensing valve, calculate the standard single dispensing amount W0.

[0072] Set the number of channels, minimum glue height, glue height step and glue amount step.

[0073] The glue height range is automatically set according to the standard glue height, number of channel numbers, minimum glue height and glue height step. Each channel number corresponds to a glue height range.

[0074] According to the glue height range, glue quantity step distance, standard total glue quantity W 总 , standard glue discharge frequency P0 and standard single-point glue quantity W0 automatically set the glue discharge quantity Wn corresponding to each glue height interval.

[0075] It should be noted that among multiple channel numbers, the valve parameter of one channel number is the glue height range corresponding to the standard glue height, and the glue output corresponding to the glue height range is the standard total glue amount; therefore, the number of channel numbers can be 3 to 10, but is not limited to this. The number of channel numbers can be expanded, and the number of channel numbers can be set according to the difference in the depth of the glue dispensing groove. When the difference in the depth of the glue dispensing groove is large, the more channel numbers are set.

[0076] During the dispensing process, the glue output of the dispensing valve is the same, and the dispensing time is the same. Based on the glue output Wn corresponding to the glue height interval, the dispensing valve's dispensing frequency is controlled to achieve control of the glue output Wn, ensuring that the glue output can meet the process requirements when the depths of the dispensing grooves of several identical workpieces are different. Specifically, in step S4, the dispensing valve is controlled to dispense glue to the workpiece dispensing groove based on the glue output Wn corresponding to the glue height interval, including:

[0077] According to the glue output Wn corresponding to the glue height range and the standard glue output, calculate the glue output frequency Pn corresponding to the glue output Wn. The calculation formula is:

[0078] Pn=(Wn / W0)*P0;

[0079] Since the valve opening time T K , Rise time T S And the fall time T X These are fixed dispensing parameters. If the dispensing frequency Pn corresponding to the dispensing amount Wn is known, the delay time T corresponding to the dispensing amount Wn can be calculated. D ;

[0080] Get the delay time T corresponding to the glue output D , the dispensing valve corresponds to the delay time T based on the glue output D To dispense glue to the workpiece dispensing slot, that is, in practical applications, a delay time T is required. D To adjust the glue dispensing frequency of the dispensing valve.

[0081] In step S4, adjusting the dispensing adjustable parameters specifically includes:

[0082] Get the single-point glue volume value W 单 , standard glue frequency P0 and standard single glue amount W0, calculate the single glue amount value W 单 The desired dispensing frequency P of the lower dispensing valve 期望 , the calculation formula is:

[0083] P 期望 =W0*P0 / W 单 ;

[0084] According to the calculated expected glue frequency P 期望 The calculation formula for the glue discharge time T' that needs to be compensated is:

[0085] T'=1000 / P 期望 ;

[0086] Calculate the compensation delay time T based on the glue discharge time T' to be compensated D ', the calculation formula is:

[0087] T D '=T'-T K +T S +T X ;

[0088] By compensating the delay time T D 'Realize glue amount distribution compensation.

[0089] In this embodiment, the channel number is automatically switched through the IO communication protocol, avoiding the problems of low reliability and low efficiency of setting the channel number parameters in the existing serial communication method, and improving the efficiency and reliability of dispensing when the channel number is frequently switched during the operation.

[0090] In summary, a method for distributing and compensating the amount of glue of the present invention can be used to automatically switch the channel number according to the actual height of the workpiece dispensing slot when the depth of the dispensing slot of several identical workpieces is different due to the workpiece's own error by setting the valve parameters of the multiple channel numbers of the dispensing valve. The dispensing valve is controlled to dispense glue at the workpiece dispensing position based on the amount of glue output of the switched channel number, ensuring that the amount of glue can meet the process requirements (such as the same height after filling) when the depth of the dispensing slot of several identical workpieces is different. The dispensing accuracy is high, the operation is simple, and the degree of automation is high. In addition, during the automatic dispensing process, the dispensing amount will be automatically compensated for based on the number of dispensing times, and the amount of glue will be corrected, avoiding the situation where a certain amount of glue will remain in the valve due to long-term use, resulting in low dispensing accuracy, and further improving the dispensing accuracy and efficiency.
