Description

Technical Field

[0001] The present invention relates to the technical field of product dispensing, and in particular to a glue quantity dynamic balancing method for a multi-valve dispensing machine and the multi-valve dispensing machine. Background Art

[0002] At present, when a multi-valve dispensing machine uses the same glue to dispense multiple products of the same size, some products fail to match due to damage, dirt, or product vacancies. For products that fail to match, the dispensing operation will be skipped, resulting in different actual dispensing times between multiple dispensing valves, and thus the glue residue in the glue barrel of each dispensing valve is inconsistent. In this regard, when the operator finds or the machine automatically monitors that the glue residue in the glue barrel of any dispensing valve is insufficient, the multi-valve dispensing machine needs to stop the dispensing operation, and replenish or replace the glue barrel with less glue to avoid the phenomenon of insufficient glue in a dispensing valve during the dispensing operation of the multi-valve dispensing machine. This causes the multi-valve dispensing machine to inevitably need to frequently replenish glue or replace the glue barrel during the dispensing operation, and frequent replenishment of glue or replacement of glue barrels also requires frequent stopping of the multi-valve dispensing machine, affecting the operating efficiency of the entire machine; and if the glue barrel is replaced, the remaining glue in the original glue barrel will be wasted, resulting in the problem of glue waste. Summary of the invention

[0003] The present invention provides a glue amount dynamic balancing method for a multi-valve glue dispensing machine, which can dynamically balance the glue in the glue cylinder of each glue dispensing valve, reduce the frequency of frequent shutdown of the glue dispensing valve due to glue replenishment or replacement of the glue cylinder, and improve the glue dispensing production efficiency.

[0004] The method for dynamically balancing the amount of glue used in a multi-valve glue dispensing machine according to an embodiment of the present invention comprises the following steps: S1, filling the glue cylinder of each dispensing valve of the multi-valve dispensing machine with glue; S2, moving the object to be glued to the work platform of the multi-valve glue dispensing machine, dividing the object to be glued into glue dispensing areas according to the arrangement position and number of glue dispensing valves and the glue remaining in the glue cylinder of each glue dispensing valve, and the number of glue dispensing areas corresponds to the number of glue dispensing valves one by one; S3, controlling each dispensing valve to perform dispensing operation according to the corresponding dispensing area; S4, obtaining the amount of glue remaining in each glue cylinder after the dispensing operation; S5, repeating steps S2 to S4, and when the glue remaining in the glue cylinders of the various dispensing valves is in a relatively balanced state and any of the dispensing valves cannot meet the dispensing requirements of the current dispensing operation object, returning to step S1.

[0005] The beneficial effect of the present invention is that the glue amount dynamic balancing method for a multi-valve dispensing machine of the present invention obtains the glue residue in the glue barrel of each dispensing valve, and divides the dispensing area for the dispensing operation object in combination with the glue residue. Each dispensing valve performs dispensing operation according to the divided dispensing area, and dynamically adjusts the remaining glue amount in the glue barrel corresponding to each dispensing valve to reduce the difference in glue residue between each glue barrel, so that the glue residue in each glue barrel is in a relatively balanced state, and the glue residue in each glue barrel can be reduced synchronously, avoiding the situation where the remaining glue amount in each glue barrel is large and frequent glue replenishment or replacement of glue barrels is avoided, so that glue is added to or replaced uniformly for all glue barrels. Since there is no need to frequently suspend the dispensing operation, the dispensing production efficiency is effectively improved, and at the same time, the equipment wear rate of the multi-valve dispensing machine is reduced, and the service life of the multi-valve dispensing machine is increased.

[0006] According to one embodiment of the present invention, in step S2, when the remaining glue in the glue barrel of any dispensing valve exceeds the amount of glue required for the dispensing task of at least one column / row of products in the dispensing operation object, the dispensing areas of each dispensing valve are re-divided, and the dispensing valve with more glue remaining in the glue barrel is allocated more dispensing area, and the dispensing valve with less glue remaining in the glue barrel is allocated less dispensing area or no dispensing area is allocated.

[0007] According to one embodiment of the present invention, the object to be dispensed is composed of a plurality of sub-products arranged in an array.

[0008] According to one embodiment of the present invention, in step S2, when the remaining glue in each glue cylinder is in a relatively balanced state, the object to be glued is divided into a plurality of glue dispensing areas of the same size according to the arrangement position of each glue dispensing valve, the number of glue dispensing valves and the shape of the array arrangement, the size information of each glue dispensing area is the same, and the number of sub-products in each glue dispensing area is the same.

[0009] According to one embodiment of the present invention, in step S2, when the glue residue in each glue cartridge is in a non-relative equilibrium state, that is, when the glue residue in any glue cartridge differs from the glue residue in other glue cartridges by more than the total glue amount required for dispensing of one column / row of sub-products, the object to be dispensing is re-divided into a plurality of dispensing areas of different sizes based on the glue residue in the glue cartridge of each dispensing valve, the arrangement position 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.

[0010] According to one embodiment of the present invention, in step S5, when the difference between the remaining glue amount in any glue cartridge and the remaining glue amount in other glue cartridges exceeds the total glue amount required for dispensing of one column / row of sub-products, the object to be dispensing is divided into multiple dispensing areas based on the remaining glue amount in the glue cartridge and the shape of the array arrangement, the size information of the dispensing area corresponding to the dispensing valve with more glue remaining amount is greater 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 size information is greater than the number of sub-products corresponding to the dispensing area with smaller size information.

[0011] According to one embodiment of the present invention, when the difference between the glue remaining amount in the glue barrel of any dispensing valve and the glue remaining amount in the glue barrel of other dispensing valves exceeds the total glue amount required for dispensing of a column / row of sub-products, the division of the dispensing area specifically includes the following steps: Get the glue remaining in each dispensing valve cylinder and calculate the difference in glue remaining between each cylinder D i ; Get the dispensing amount of a sub-product Q , according to the difference in glue residue between each glue cylinder D i , calculate the difference D i The number of corresponding sub-products m i , the calculation formula is: m i = D i / Q ; Get the number of rows and columns of all sub-products. m i When the number of products is greater than one column / row, the dispensing valve with less glue remaining in the glue cartridge allocates at least one column / row less sub-products or no dispensing sub-products, while the dispensing valve with more glue remaining in the glue cartridge allocates at least one column / row more sub-products.

[0012] According to one embodiment of the present invention, step S3 specifically includes the following steps: Each of the dispensing valves obtains 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 matching; The dispensing valve performs dispensing operations according to the coordinates of the corresponding sub-product.

[0013] According to one embodiment of the present invention, when a plurality of the dispensing valves are arranged in parallel transversely on a three-axis driving mechanism of a multi-valve dispensing machine, the dispensing area is divided into columns based on the shape of the objects to be dispensed being arranged in an array; When a plurality of the dispensing valves are longitudinally arranged in parallel on a three-axis driving mechanism of the multi-valve dispensing machine, the dispensing areas are divided into rows based on the shape of the objects to be dispensed being arranged in an array.

[0014] According to one embodiment of the present invention, the number of the dispensing valves is at least two.

[0015] According to one embodiment of the present invention, step S4 includes: The remaining glue amount in the rubber cylinder is monitored by a liquid level detector arranged on the rubber cylinder to obtain the remaining glue amount in the rubber cylinder; Alternatively, the amount of glue remaining in the glue cylinder can be calculated by obtaining the corresponding number of needle strikes of each dispensing valve during the dispensing operation and combining the glue output of the dispensing valve.

[0016] According to a multi-valve glue dispensing machine of an embodiment of the present invention, the multi-valve glue dispensing machine adopts the glue amount dynamic balancing method for the multi-valve glue dispensing machine as described above.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Example 1 The present application embodiment provides a method for dynamically balancing the amount of glue used in a multi-valve glue dispensing machine, such as Figure 1 As shown, the method comprises the following steps: S1, fill the glue cylinder of each dispensing valve of the multi-valve dispensing machine with glue; the number of dispensing valves is at least two.

[0034] S2, moving the object to be glued to the work platform of the multi-valve glue dispensing machine, dividing the glue dispensing area for the object to be glued according to the arrangement position and the number of each glue dispensing valve, combined with the remaining glue in the glue barrel of each glue dispensing valve, and the number of glue dispensing areas corresponds to the number of glue dispensing valves one by one; further, when the remaining glue in the glue barrel of any dispensing valve exceeds the glue amount required for the glue dispensing task of at least one column / row of products in the object to be glued, the glue dispensing areas of each dispensing valve are re-divided, and the dispensing valve with more glue remaining in the glue barrel is allocated more dispensing area, and the dispensing valve with less glue remaining in the glue barrel is allocated less dispensing area or no dispensing area.

[0035] S3, controls each dispensing valve to perform dispensing operation according to the corresponding dispensing area.

[0036] S4, obtaining the glue remaining amount in each glue cylinder of each dispensing valve after completing the current dispensing operation.

[0037] S5, repeat steps S2 to S4, and when the glue remaining in the glue barrel of each dispensing valve is in a relatively balanced state and any one of the dispensing valves cannot meet the dispensing requirements of the current dispensing operation object, return to step S1. Repeating steps S2 to S4 can dynamically balance the glue remaining in the glue barrel of each dispensing valve. At the same time, when any one of the dispensing valves cannot meet the dispensing requirements of the current dispensing operation object, due to dynamic balance, the difference in the glue remaining in the glue barrel of each dispensing valve is small. When replenishing glue, it is necessary to uniformly replenish glue or replace the glue barrel of each dispensing valve, thereby reducing the frequency of frequent shutdown of the dispensing machine due to replenishing glue or replacing the glue barrel for a certain dispensing valve.

[0038] In this embodiment, the object to be dispensed is composed of a plurality of sub-products arranged in an array. The shape of the array arrangement may be, but is not limited to, a rectangular or square shape. Figure 2 or Figure 3 shown.

[0039] In this embodiment, in step S2, when the glue residue in each glue cylinder is in a relatively balanced state, that is, the difference between the glue residue in each glue cylinder is within the threshold range, the object to be glued is divided into a plurality of glue dispensing areas of the same size according to the arrangement position of each glue dispensing valve, the number of glue dispensing valves and the shape of the array arrangement. The size information of each glue dispensing area is the same, and the number of sub-products in each glue dispensing area is the same. Taking the number of glue dispensing valves as four as an example, a plurality of sub-products are arranged in an 8*8 square array, and the object to be glued is divided into four glue dispensing areas of the same size, see Figure 4 and Figure 5 shown.

[0040] It should be noted that after the dispensing operation, due to the process errors between the various dispensing valves, the remaining glue amount in each glue barrel 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 barrel is within the threshold range, the dispensing area on the object to be dispensing is evenly divided, and there is no need to dynamically balance the glue remaining in the glue barrel, thereby improving the dispensing efficiency.

[0041] When the glue residue in each glue cartridge is in a non-relative equilibrium state, that is, when the glue residue in any glue cartridge differs from the glue residue in other glue cartridges by more than the total glue amount required for dispensing a column / row of sub-products, the object to be dispensing is divided into a plurality of dispensing areas of different sizes based on the glue residue in the glue cartridge, the arrangement position 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 a large glue residue is greater than the size information of the dispensing area corresponding to the dispensing valve with a small glue residue, and the number of sub-products corresponding to the dispensing area with a large size information is greater than the number of sub-products corresponding to the dispensing area with a small size information, see Figure 6 When the glue remaining in each glue barrel is in a non-relatively balanced state, by repeating the above steps once or multiple times, it can be ensured that the glue remaining in each glue barrel is in a relatively balanced state after each dispensing valve completes the current dispensing task.

[0042] Specifically, the division of the dispensing area includes the following steps: Get the glue remaining in each dispensing valve cylinder and calculate the difference in glue remaining between each cylinder D i ; Get the dispensing amount of a sub-product Q , according to the difference in glue residue between each glue cartridge D i , calculate the difference D i The number of corresponding sub-products m i , the calculation formula is: m i = D i / Q ; Get the number of rows and columns of all sub-products. m iWhen the number of products is greater than one column / row, the dispensing valve with less glue remaining in the glue cartridge allocates at least one column / row less sub-products or no dispensing sub-products, while the dispensing valve with more glue remaining in the glue cartridge allocates at least one column / row more sub-products.

[0043] For example, when dispensing valve 1 is full of glue, some sub-products fail to match the glue, resulting in a decrease in the actual number of dispensing times of dispensing valve 1. The actual number of dispensing times of dispensing valve 1 is less, which makes the remaining glue in the glue cylinder of dispensing valve 1 greater than the remaining glue in other glue cylinders. The remaining glue in other glue cylinders is the same. The difference in the remaining glue in the glue cylinder of dispensing valve 1 is calculated as D 1. Based on the difference D 1 Determine the number of sub-products that can be dispensed with this glue volume difference. This number is m 1. If the quantity m 1 is greater than the number of products in a column / row, dispensing valve 1 will allocate an extra column of sub-products, such as Figure 6 As shown, if the quantity m If 1 is greater than the number of products in two columns / rows, one more column of sub-products will be allocated to dispensing valve 1 and dispensing valve 2. When the dispensing area is divided according to the number of columns and rows of sub-products in this embodiment, the number of columns / rows will be evenly allocated to each dispensing valve operation according to the arrangement position of the dispensing valve. If it cannot be evenly divided, it is necessary to ensure that the number of columns / rows in the dispensing area of ​​each dispensing valve is not much different, so as to reduce the difference between the remaining glue in each glue barrel.

[0044] It should be noted that the object to be dispensed is composed of several sub-products arranged in an array. In order to improve the dispensing efficiency and the control of each dispensing valve, the dispensing valves are arranged in sequence on the three-axis drive mechanism of the multi-valve dispensing machine. For example, the dispensing area of ​​dispensing valve 1 must be close to the dispensing area of ​​dispensing valve 2. Furthermore, the three-axis drive structure of the multi-valve dispensing machine determines the division method of the dispensing area in columns or rows. For example, when multiple dispensing valves are arranged horizontally and in parallel on the three-axis drive mechanism of the multi-valve dispensing machine, the dispensing area will be divided by column based on the shape of the array arrangement of the object to be dispensed, see Figure 5 When a plurality of the dispensing valves are longitudinally arranged in parallel on the three-axis drive mechanism of the multi-valve dispensing machine, the dispensing area will be divided into rows based on the shape of the array arrangement of the objects to be dispensed, see Figure 6 shown.

[0045] In this embodiment, step S3 specifically includes the following steps: 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 matching; The dispensing valve performs dispensing operations according to the coordinates of the corresponding sub-products, see Figure 7or Figure 8 As shown. The dispensing track of the dispensing valve is not fixed. It can be a dispensing operation from bottom to top in rows, or a dispensing operation from left to right in rows. At the same time, it can be an S-shaped dispensing track or a Z-shaped dispensing track.

[0046] In this embodiment, obtaining the amount of glue remaining in each glue cylinder after the glue dispensing operation includes: A liquid level detector is provided on the rubber cylinder, and the residual glue in the rubber cylinder is monitored by the liquid level detector to obtain the amount of glue remaining in the rubber cylinder.

[0047] Alternatively, the amount of glue remaining in the glue barrel can be calculated by obtaining the corresponding number of strikes of each dispensing valve during the dispensing operation and combining it with the single glue output of the dispensing valve. If the single glue output of the dispensing valve is G, and the number of strikes of the dispensing valve for the current dispensing area is N, then the amount of glue currently consumed by the dispensing valve in the glue barrel is G*N1. Wait for the next polling and repeat this step. If the number of strikes of the dispensing valve for the next dispensing area is N2, then the amount of glue consumed by the dispensing valve in the glue barrel next time is G*N2. Let the total glue amount be G. 总 , the amount of glue remaining in the glue cylinder is G 总 -G*N1-G*N2.

[0048] In this embodiment, since the size and structure of the dispensing area sub-products are the same, the dispensing parameter settings of each dispensing valve are the same.

[0049] To summarize, the method for dynamic balancing of glue amount for a multi-valve dispensing machine of the present embodiment obtains the glue residue in the glue barrel of each dispensing valve, and divides the dispensing area for the operation object to be dispensed according to the glue residue. Each dispensing valve performs dispensing operation according to the divided dispensing area, and dynamically adjusts the remaining glue amount in the glue barrel corresponding to each dispensing valve to narrow the difference in glue residue between each glue barrel, so that the glue residue in each glue barrel is in a relatively balanced state, and the glue residue in each glue barrel can be reduced synchronously, avoiding the situation where the remaining glue amount in each glue barrel is large and frequent replenishment of glue or replacement of glue barrels is avoided, so that glue is added to or replaced uniformly for all glue barrels. Since there is no need to frequently suspend the dispensing operation, the dispensing production efficiency is effectively improved, and at the same time, the equipment wear rate of the multi-valve dispensing machine is reduced, and the service life of the multi-valve dispensing machine is increased.
