Description

Technical Field

[0001] The present invention relates to the technical field of product dispensing, and particularly to a glue volume dynamic balance method for a multi-valve dispenser and the multi-valve dispenser thereof. Background Art

[0002] At present, when a multi-valve dispenser uses the same type of glue to dispense glue on multiple products of the same size, since some products fail to match due to damage, dirt, or product vacancy, etc., the products that fail to match will be skipped and no glue dispensing operation is required. As a result, the actual number of glue dispensing times among multiple dispensing valves is different, and further the remaining glue amounts in the glue cylinders of each dispensing valve are inconsistent. In this regard, when the operator checks or the machine automatically monitors that the glue amount in the glue cylinder of any one dispensing valve is insufficient, it is necessary to stop the glue dispensing operation of the multi-valve dispenser, and replenish the glue in the glue cylinder with less glue or replace the glue cylinder, so as to avoid the phenomenon that the glue in a certain dispensing valve is insufficient during the glue dispensing operation of the multi-valve dispenser. This causes the multi-valve dispenser to inevitably need to frequently replenish glue or replace the glue cylinder during the glue dispensing operation, and frequently replenishing glue or replacing the glue cylinder also requires frequently stopping the glue dispensing operation of the multi-valve dispenser, affecting the overall operation efficiency of the machine; moreover, if the glue cylinder is selected to be replaced, the remaining glue in the original glue cylinder will be wasted, resulting in the problem of glue waste. Summary of the Invention

[0003] The present invention provides a glue volume dynamic balance method for a multi-valve dispenser, which can dynamically balance the glue in the glue cylinders of each dispensing valve, reduce the frequency of frequent shutdowns caused by replenishing glue or replacing the glue cylinder for the dispensing valve, and improve the glue dispensing production efficiency.

[0004] The glue volume dynamic balance method for a multi-valve dispenser according to an embodiment of the present invention includes the following steps:

[0005] S1, filling the glue cylinders of each dispensing valve of the multi-valve dispenser with glue;

[0006] S2, moving the object to be dispensed to the working platform of the multi-valve dispenser, and dividing the dispensing area for the object to be dispensed according to the arrangement positions of each dispensing valve and the number of dispensing valves, in combination with the remaining glue amounts in the glue cylinders of each dispensing valve, the number of dispensing areas corresponding one-to-one to the number of dispensing valves;

[0007] S3, controlling each dispensing valve to perform glue dispensing operation according to the corresponding dispensing area;

[0008] S4, obtaining the glue amount remaining in each glue cylinder after the glue dispensing operation;

[0009] S5. Repeat steps S2 to S4. When the remaining glue amounts in the cartridges of all dispensing valves are in a relatively balanced state and any one of the dispensing valves cannot meet the dispensing requirements of the current object to be dispensed, return to step S1.

[0010] The beneficial effect of the present invention is that the glue amount dynamic balance method for a multi-valve dispenser of the present invention obtains the remaining glue amounts in the cartridges of all dispensing valves, divides the dispensing areas of the object to be dispensed in combination with the remaining glue amounts, and each dispensing valve performs dispensing operations according to the divided dispensing areas, dynamically adjusting the remaining glue amounts in the cartridges corresponding to each dispensing valve to reduce the difference in the remaining glue amounts between the cartridges, so that the remaining glue amounts in the cartridges are in a relatively balanced state, enabling the remaining glue amounts in the cartridges to decrease synchronously, avoiding large differences in the remaining glue amounts in the cartridges and frequent glue replenishment or cartridge replacement, facilitating the unified addition of glue or cartridge replacement for all cartridges, effectively improving the dispensing production efficiency since there is no need to frequently pause the dispensing operation, and at the same time reducing the equipment wear rate of the multi-valve dispenser and increasing the service life of the multi-valve dispenser.

[0011] According to an embodiment of the present invention, in step S2, when the remaining glue amount in the cartridge of any one dispensing valve exceeds the glue amount required for the dispensing tasks of at least one column / row of products in the object to be dispensed, re-divide the dispensing areas of each dispensing valve, allocate more dispensing areas to the dispensing valve with more remaining glue in the cartridge, and allocate fewer or no dispensing areas to the dispensing valve with less remaining glue in the cartridge.

[0012] According to an embodiment of the present invention, the object to be dispensed is composed of a number of sub-products arranged in an array.

[0013] According to an embodiment of the present invention, in step S2, when the remaining glue amounts in the cartridges are in a relatively balanced state, divide the object to be dispensed into multiple dispensing areas of the same size according to the arrangement positions of the dispensing valves, the number of dispensing valves, and the shape arranged in an array. The size information of each dispensing area is the same, and the number of sub-products in each dispensing area is the same.

[0014] According to an embodiment of the present invention, in step S2, when the remaining glue amounts in the cartridges are not in a relatively balanced state, that is, when the difference between the remaining glue amount in any one cartridge and the remaining glue amounts in other cartridges exceeds the total glue amount required for dispensing one column / row of sub-products, re-divide the object to be dispensed into multiple dispensing areas of different sizes based on the remaining glue amounts in the cartridges of the dispensing valves, the arrangement positions of the dispensing valves, the number of dispensing valves, and the shape arranged in an array. The size information of each dispensing area is the same, and the number of sub-products in each dispensing area is the same.

[0015] According to an embodiment of the present invention, in the step S5, when the glue remaining amount in any glue cylinder differs from the glue remaining amount in other glue cylinders by more than the total glue amount required for dispensing one column / one row of sub-products, the object to be dispensed is divided into multiple dispensing areas based on the remaining glue amount in the glue cylinders and the shape arranged in an array. The size information of the dispensing area corresponding to the dispensing valve with more glue remaining amount is larger than the size information of the dispensing area corresponding to the dispensing valve with less glue remaining amount, and the number of sub-products corresponding to the dispensing area with larger dispensing area size information is more than the number of sub-products corresponding to the dispensing area with smaller dispensing area size information.

[0016] According to an embodiment of the present invention, when the glue remaining amount in the glue cylinder of any one dispensing valve differs from the glue remaining amount in the glue cylinders of other dispensing valves by more than the total glue amount required for dispensing one column / one row of sub-products, the division of the dispensing area specifically includes the following steps:

[0017] Obtain the glue remaining amount in the glue cylinders of each dispensing valve, and calculate the difference in the glue remaining amount between each glue cylinder D i ;

[0018] Obtain the dispensing amount of one sub-product Q , and according to the difference in the glue remaining amount between each glue cylinder D i , calculate the number of sub-products corresponding to this difference D i , and the calculation formula is: m i = m i = D i / Q ;

[0019] Obtain the number of rows and columns of all sub-products arranged. When m i is greater than the number of products in one column / one row, then the dispensing valve with less glue remaining amount in the glue cylinder is allocated at least one column / one row of sub-products less or no dispensing sub-products, while the dispensing valve with more glue remaining amount in the glue cylinder is allocated at least one column / one row of sub-products more.

[0020] According to an embodiment of the present invention, the step S3 specifically includes the following steps:

[0021] Each of the dispensing valves obtains the row and column information of the sub-products in the corresponding dispensing area, calculates the position of each sub-product in its dispensing area, and obtains the coordinates of each sub-product through visual recognition and matching;

[0022] The dispensing valve performs dispensing operations according to the coordinates of the corresponding sub-products.

[0023] According to an embodiment of the present invention, when multiple dispensing valves are arranged horizontally side by side on the three-axis drive mechanism of a multi-valve dispenser, the dispensing area is divided by columns based on the shape of the object to be dispensed in an array layout.

[0024] When multiple dispensing valves are arranged vertically side by side on the three-axis drive mechanism of a multi-valve dispenser, the dispensing area is divided by rows based on the shape of the object to be dispensed in an array layout.

[0025] According to an embodiment of the present invention, the number of the dispensing valves is at least two.

[0026] According to an embodiment of the present invention, the step S4 includes:

[0027] Monitoring the remaining glue amount in the glue cylinder through the liquid level detector provided on the glue cylinder to obtain the glue amount of the remaining glue in the glue cylinder;

[0028] Or calculating the remaining glue amount in the glue cylinder by obtaining the corresponding number of needle strikes of each dispensing valve during the dispensing operation and combining with the glue output amount of the dispensing valve.

[0029] A multi-valve dispenser according to an embodiment of the present invention adopts the above-mentioned glue amount dynamic balance method for a multi-valve dispenser.

[0046] Embodiment 1

[0047] The embodiment of the present application provides a method for dynamic balance of glue volume for a multi-valve dispensing machine, as Figure 1 shown. The method includes the following steps:

[0048] S1, Fill the glue cartridges of each dispensing valve of the multi-valve dispensing machine with glue; the number of dispensing valves is at least two.

[0049] S2, Move the object to be dispensed to the working platform of the multi-valve dispensing machine. According to the arrangement positions of the respective dispensing valves and the number of dispensing valves, combined with the remaining glue amounts in the glue cartridges of the respective dispensing valves, divide the dispensing areas for the object to be dispensed. The number of dispensing areas corresponds one-to-one with the number of dispensing valves. Further, when the remaining glue amount in any one glue cartridge exceeds the glue amount required for the dispensing task of at least one column / row of products in the object to be dispensed, re-divide the dispensing areas of the respective dispensing valves, allocate more dispensing areas to the dispensing valve with a larger remaining glue amount in the glue cartridge, and allocate fewer or no dispensing areas to the dispensing valve with a smaller remaining glue amount in the glue cartridge.

[0050] S3, Control each dispensing valve to perform a dispensing operation according to the corresponding dispensing area.

[0051] S4, Obtain the remaining glue amounts in the respective glue cartridges of each dispensing valve after completing the current dispensing operation.

[0052] S5, Repeat steps S2 to S4. When the remaining glue amounts in the respective glue cartridges of each dispensing valve are in a relatively balanced state and any one of the dispensing valves cannot meet the dispensing requirements of the current object to be dispensed, return to step S1. Repeating steps S2 to S4 can dynamically balance the remaining glue amounts in the respective glue cartridges of each dispensing valve. At the same time, when any one of the dispensing valves cannot meet the dispensing requirements of the current object to be dispensed, due to the dynamic balance, the difference in the remaining glue amounts in the respective glue cartridges of each dispensing valve is small. When replenishing glue, it is necessary to uniformly replenish glue or replace the glue cartridges for each glue cartridge of each dispensing valve, reducing the frequency of frequent shutdown of the dispensing machine for replenishing glue or replacing the glue cartridge for a certain dispensing valve.

[0053] In this embodiment, the object to be dispensed is composed of a number of sub-products arranged in an array. The shape of the array arrangement can be, but is not limited to, a rectangle or a square, as shown in Figure 2 or Figure 3 shown.

[0054] In this embodiment, in step S2, when the glue remaining amounts in each glue cylinder are in a relatively balanced state, that is, the difference between the glue remaining amounts in each glue cylinder is within the threshold range, the object to be dispensed is divided into multiple dispensing areas of the same size according to the arrangement positions of each dispensing valve, the number of dispensing valves, and the shape of the array arrangement. The size information of each dispensing area is the same, and the number of sub-products in each dispensing area is the same. Taking the number of dispensing valves as four as an example, a number of sub-products are arranged in an 8*8 square array, and the object to be dispensed is divided into four dispensing areas of the same size, as shown in Figure 4 and Figure 5 shown.

[0055] It should be noted that after the dispensing operation, due to the process error between each dispensing valve, the glue remaining amounts in each glue cylinder of the dispensing valve cannot be exactly the same. The threshold range set in this embodiment is less than the total glue amount required for dispensing a column / row of sub-products. If the difference between the glue amounts in each glue cylinder is within the threshold range, the dispensing areas on the object to be dispensed are evenly divided, and it is not necessary to perform dynamic balancing on the glue remaining amounts in the glue cylinders, thereby improving the dispensing efficiency.

[0056] When the glue remaining amounts in each glue cylinder are in a non-relatively balanced state, that is, when the glue remaining amount in any one glue cylinder differs from the glue remaining amounts in other glue cylinders by more than the total glue amount required for dispensing a column / row of sub-products, the object to be dispensed is divided into multiple dispensing areas of different sizes based on the glue remaining amounts in the glue cylinders, the arrangement positions of each dispensing valve, the number of dispensing valves, and the shape of the array arrangement. The size information of the dispensing area corresponding to the dispensing valve with more glue remaining is greater than the size information of the dispensing area corresponding to the dispensing valve with less glue remaining, and the number of sub-products corresponding to the dispensing area with larger size information is more than the number of sub-products corresponding to the dispensing area with smaller size information, as shown in Figure 6 shown. When the glue remaining amounts in each glue cylinder are in a non-relatively balanced state, by repeating the above steps once or multiple times, it can be ensured that the glue remaining amounts in each glue barrel are in a relatively balanced state after each dispensing valve completes the current dispensing task.

[0057] Specifically, the division of the dispensing area includes the following steps:

[0058] Obtain the glue remaining amounts in the glue cylinders of each dispensing valve, and calculate the difference between the glue remaining amounts in each glue cylinder D i ;

[0059] Obtain the dispensing amount of a sub-product Q , according to the difference in the remaining glue amount between each glue cylinder D i , calculate this difference D i The number of sub-products corresponding to it m i , and the calculation formula is: m i = D i / Q ;

[0060] Obtain the number of rows and columns in which all sub-products are arranged. When m i is greater than the number of products in one column / one row, then the dispensing valve with less remaining glue in the glue cylinder distributes at least one column / one row of sub-products less or does not distribute dispensing sub-products, while the dispensing valve with more remaining glue in the glue cylinder distributes at least one column / one row of sub-products more.

[0061] For example: taking the case where when dispensing with the dispensing valve 1 under full glue condition, the dispensing of some sub-products fails to match, resulting in a decrease in the actual dispensing times of the dispensing valve 1 as an example for further explanation. The decrease in the actual dispensing times of the dispensing valve 1 makes the remaining glue amount in the glue cylinder of the dispensing valve 1 greater than the remaining glue amounts in other glue cylinders, and the remaining glue amounts of other glue cylinders are the same. Calculate the difference in the remaining glue amount in the glue cylinder of the dispensing valve 1 as D 1. According to the difference D 1, determine the number of sub-products that can be dispensed with this glue amount difference, and this number is m 1. If the number m 1 is greater than the number of products in one column / one row, the dispensing valve 1 will distribute one more column of sub-products. As Figure 6 shown, if the number m 1 is greater than the number of products in two columns / two rows, the dispensing valve 1 and the dispensing valve 2 will distribute one more column of sub-products. When dividing the dispensing area according to the number of rows and columns of sub-products in this embodiment, first, the number of columns / rows will be evenly distributed to each dispensing valve for operation according to the arrangement position of the dispensing valves. For the situation that cannot be evenly divided, it is necessary to ensure that the difference in the number of columns / rows in the dispensing areas of each dispensing valve is not large, and reduce the difference in the remaining glue amounts in each glue barrel.

[0062] It should be noted that the object to be dispensed is composed of several sub-products arranged in an array. To improve the dispensing efficiency and control of each dispensing valve, the dispensing valves are arranged side by side in sequence on the three-axis drive mechanism of the multi-valve dispenser. For example, the dispensing area of dispensing valve 1 must be adjacent to the dispensing area of dispensing valve 2. Further, the three-axis drive structure of the multi-valve dispenser determines the division method of the dispensing area by column or by row. For example, when multiple dispensing valves are arranged horizontally side by side on the three-axis drive mechanism of the multi-valve dispenser, the dispensing area will be divided by column based on the shape of the object to be dispensed arranged in an array. Refer to Figure 5 as shown; when multiple dispensing valves are arranged vertically side by side on the three-axis drive mechanism of the multi-valve dispenser, the dispensing area will be divided by row based on the shape of the object to be dispensed arranged in an array. Refer to Figure 6 as shown.

[0063] In this embodiment, step S3 specifically includes the following steps:

[0064] Each dispensing valve obtains the row and column information of the sub-products in the corresponding dispensing area, calculates the position of each sub-product in its dispensing area, and obtains the coordinates of each sub-product through visual recognition and matching.

[0065] The dispensing valve performs dispensing operations according to the coordinates of the corresponding sub-products. Refer to Figure 7 or Figure 8 as shown. The dispensing trajectory of the dispensing valve is not fixed. It can be dispensing row by row from bottom to top, or row by row from left to right. At the same time, it can be an S-shaped dispensing trajectory or a Z-shaped dispensing trajectory.

[0066] In this embodiment, obtaining the remaining glue volume in each glue cylinder after the dispensing operation includes:

[0067] A liquid level detector is provided on the glue cylinder to monitor the remaining glue in the glue cylinder and obtain the remaining glue volume in the glue cylinder.

[0068] Alternatively, by obtaining the corresponding number of needle strikes of each dispensing valve during the dispensing operation and combining with the single-time glue output of the dispensing valve, calculate the remaining glue volume in the glue cylinder. For example, if the single-time glue output of the dispensing valve is G and the number of needle strikes of the dispensing valve for the current dispensing area is N, then the glue volume consumed by the dispensing valve in the current glue cylinder is G*N1. Wait for the next polling and repeat this step. If the number of needle strikes of the dispensing valve for the next dispensing area is N2, then the glue volume consumed by the dispensing valve in the next time is G*N2. Let the total glue volume be G 总 , and the remaining glue volume in the glue cylinder is G 总 -G*N1 - G*N2.

[0069] In this embodiment, since the sizes and structures of the sub-products in the dispensing area are the same, the dispensing parameters of each dispensing valve are set identically.

[0070] In summary, for the glue volume dynamic balance method of the multi-valve dispenser in this embodiment, by obtaining the remaining glue volume in the glue buckets of each dispensing valve and combining the remaining glue volume to divide the dispensing area of the object to be dispensed, each dispensing valve performs dispensing operations according to the divided dispensing area, dynamically adjusts the remaining glue volume in the glue bucket corresponding to each dispensing valve, reduces the difference in the remaining glue volume between each glue bucket, makes the remaining glue volume in each glue bucket in a relatively balanced state, enables the remaining glue volume in each glue bucket to decrease synchronously, avoids the large difference in the remaining glue volume in each glue bucket and the situation of frequently replenishing glue or replacing glue buckets, facilitates the unified addition of glue or replacement of glue buckets to all glue buckets, effectively improves the dispensing production efficiency because there is no need to frequently pause the dispensing operation, and at the same time reduces the equipment wear rate of the multi-valve dispenser and improves the service life of the multi-valve dispenser.
