Description

Technical Field

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

[0002] The glue dispensing machine is a process equipment used in the field of product production. Its application scope covers the processes of product bonding, potting, coating, sealing, filling, dripping, marking and gluing. The glue dispensing machine has a decisive influence on the efficiency, accuracy, and process of glue dispensing. Many products that need glue dispensing are products arranged in an array in an operating area, and then glue is dispensed on the products through a glue dispensing valve.

[0003] During the operation of the dispensing machine, the dispensing machine may encounter some uncontrollable factors. For example, if the relevant parts of the dispensing head are abnormal, the system will immediately stop dispensing once it detects this situation. This results in the failure to complete the process of some products. Usually, the dispensing process of a product contains multiple tracks, some of which need to be repeatedly dispensed. Since the dispensing process is set in advance in the dispensing machine system, when an abnormality occurs, the dispensing machine will ensure that the current track is complete, that is, the dispensing machine will complete the dispensing operation of the current track. However, the unfinished track may not be able to continue the operation. In the face of this situation, the existing technology mainly relies on manual glue filling. The operator needs to first check which tracks of which products have not completed the dispensing, and then re-compile the process program to fill the missing tracks. This method is not only time-consuming and has low glue filling efficiency, but also requires extremely high carefulness of the operator and is prone to errors. For example, the number of times the missing track is filled is incorrect, the track is inaccurate, and the amount of glue is inappropriate, resulting in a low product yield and high labor costs. Summary of the invention

[0004] The technical problem to be solved by the present invention is: in order to solve the technical problem that the prior art is not only time-consuming, but also has low glue filling efficiency, is prone to errors, and has low product yield, and high labor costs. The present invention provides an automatic glue filling method for a multi-valve glue dispensing machine, which can automatically fill glue, improve glue filling efficiency, reduce labor costs, and improve product yield.

[0005] According to the automatic glue filling method of the multi-valve glue dispensing machine of the embodiment of the present invention, the number of glue dispensing valves is at least two, and each glue dispensing valve is controlled to perform glue dispensing operation on the product to be glued in the corresponding glue dispensing area; The automatic glue filling method comprises the following steps: Collect the dispensing operation information of each dispensing valve in the corresponding dispensing area in real time. When one of the dispensing valves has an abnormality during the dispensing operation, control the abnormal dispensing valve to stop working, and lock the operation information of the dispensing product operated by the abnormal dispensing valve; Obtaining the latched operation information of the abnormal dispensing valve, determining the dispensing area of ​​the abnormal dispensing valve as the area to be filled with glue according to the latched operation information, and obtaining the filling operation parameters of the product to be filled with glue in the area to be filled with glue; Obtain the glue remaining amount in the glue cylinder after each normal dispensing valve completes the dispensing operation in the corresponding dispensing area; According to the glue remaining in the glue cylinder of each normal dispensing valve, select a normal dispensing valve for operation in the area to be filled with glue as the glue filling dispensing valve; Based on the coordinate position of the abnormal dispensing valve and the coordinate position of the glue replenishing dispensing valve, the glue replenishing operation parameters of the product to be replenished are corrected in the operation coordinates, and the glue replenishing dispensing valve is controlled to automatically replenish the product to be replenished based on the glue replenishing operation parameters after the operation coordinate correction.

[0006] The beneficial effect of the present invention is that the automatic glue filling method of the multi-valve dispensing machine of the present invention can avoid the problems of long time consumption, low dispensing efficiency, and easy errors, which lead to poor product quality, compared with the existing manual glue filling method. When an abnormality occurs in a dispensing valve during the dispensing operation, the operation information of the dispensing product can be latched, and glue can be filled based on the glue filling operation parameters of the abnormal dispensing valve through the normally working dispensing valve, thereby improving the glue filling efficiency, reducing labor costs, and improving the product yield.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Example 1 An embodiment of the present application provides an automatic glue filling method for a multi-valve dispensing machine, wherein the number of dispensing valves is at least two, and each dispensing valve is controlled to perform a dispensing operation on a product to be dispensed in a corresponding dispensing area.

[0027] The automatic glue filling method comprises the following steps: The information of the dispensing operation of each dispensing valve in the corresponding dispensing area is collected in real time. When one of the dispensing valves fails during the dispensing operation, the abnormal dispensing valve is controlled to stop operating, and the operation information of the dispensing product of the abnormal dispensing valve is latched.

[0028] It should be noted that in order to ensure the integrity of the ongoing dispensing trajectory, when one of the dispensing valves malfunctions during the dispensing operation, the abnormal dispensing valve will continue to perform a single dispensing operation on the single product to be dispensed that is currently in operation until the dispensing of the current single product to be dispensed is completed, and then the abnormal dispensing valve will be controlled to stop the operation.

[0029] Obtain the latched operation information of the abnormal dispensing valve, determine that the dispensing area of ​​the abnormal dispensing valve is the area to be filled with glue according to the latched operation information, and obtain the filling operation parameters of the product to be filled in the area to be filled with glue; wherein, the latched operation information of the abnormal dispensing valve includes: operation information of abnormal operation of the dispensing product and operation information of non-dispensing operation.

[0030] Obtain the glue remaining amount in the glue cylinder after each normal dispensing valve completes the dispensing operation in the corresponding dispensing area.

[0031] According to the glue remaining amount in the glue barrel of each normal dispensing valve, a normal dispensing valve used for the area to be filled with glue is selected as the glue filling dispensing valve; if the glue remaining amount in the glue barrel of each normal dispensing valve is compared, the normal dispensing valve with the largest glue remaining amount in the glue barrel is selected as the glue filling dispensing valve.

[0032] Based on the coordinate position of the abnormal dispensing valve and the coordinate position of the glue replenishing dispensing valve, the operating coordinates of the glue replenishing operation parameters of the product to be replenished are corrected, and the glue replenishing dispensing valve is controlled to automatically replenish the product to be replenished based on the glue replenishing operation parameters after the operating coordinate correction.

[0033] In this embodiment, the number of dispensing valves is at least two. Figure 2 As shown, the multi-valve dispensing machine includes: a three-axis motion mechanism, which includes a first drive mechanism 31 driven along a first direction, a second drive mechanism 32 driven along a second direction, and a plurality of third drive mechanisms 33 driven along a third direction, the first drive mechanism 31 is slidably arranged on the second drive mechanism 32, and a plurality of third drive mechanisms 33 are slidably arranged on the first drive mechanism 31; each third drive mechanism 33 is connected to a dispensing valve. The first direction is perpendicular to the second direction.

[0034] In this embodiment, the dispensing valves correspond to the third driving mechanisms 33 one by one, and the dispensing valves are installed on the corresponding third driving mechanisms, and the plurality of third driving mechanisms are slidably arranged on the first driving mechanism. At this time, each dispensing valve is on the same horizontal line, so that the synchronous operation of each dispensing valve on the dispensing product can be realized. Based on the coordinate position of the abnormal dispensing valve and the coordinate position of the dispensing valve, the operation coordinate correction of the dispensing operation parameters of the product to be dispensing includes the following steps: The coordinate positions of the abnormal dispensing valve and the glue replenishing dispensing valve in the first direction are obtained, and the coordinate difference between the abnormal dispensing valve and the glue replenishing dispensing valve in the first direction is calculated, and the operation coordinates of the glue replenishing dispensing valve moving to the glue replenishing area are corrected according to the coordinate difference. This embodiment can realize the correction of the operation coordinates of the glue replenishing operation parameters in the first direction (X direction or Y direction) of the glue replenishing product.

[0035] Further, obtaining the coordinate positions of the abnormal dispensing valve and the glue replenishing dispensing valve in the first direction includes: Set a reference point on the dispensing work platform of the multi-valve dispensing machine.

[0036] Move each dispensing valve to a reference point to obtain a first reference coordinate of each dispensing valve.

[0037] Then obtain the starting position of the dispensing area corresponding to each dispensing valve.

[0038] The coordinate position of each dispensing valve in the first direction is obtained based on the first reference coordinate and the starting point position of the dispensing area corresponding to each dispensing valve.

[0039] In this embodiment, the third driving mechanism is a Z-direction driving mechanism. When the first driving mechanism 31 is an X-direction driving mechanism, the second driving mechanism 32 is a Y-direction driving mechanism; or when the first driving mechanism 31 is a Y-direction driving mechanism, the second driving mechanism 32 is an X-direction driving mechanism.

[0040] In this embodiment, the amount of glue in the glue cylinder after each dispensing valve completes the dispensing operation under normal working conditions is obtained, which includes: The remaining amount of glue in the rubber cylinder is obtained through a liquid level detector installed on the rubber cylinder.

[0041] Alternatively, the remaining glue in the glue barrel is calculated by obtaining the number of strikers generated by the dispensing valve during the dispensing operation and the single glue output of the dispensing valve. Specifically, the consumed glue amount in the barrel is calculated based on the number of strikers generated by each dispensing valve during the dispensing operation and the glue output of the dispensing valve, and then the amount of glue remaining in the dispensing valve glue barrel is obtained by subtracting the consumed glue amount from the total glue amount. If the single glue output of the dispensing valve is G, and the number of strikers for the dispensing valve in 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 strikers 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. Assume the total glue amount is G. 总 , the amount of glue remaining in the glue cylinder is G 总 -G*N1-G*N2.

[0042] Compared with the existing manual glue filling method, the automatic glue filling method of the multi-valve dispensing machine of this embodiment can avoid the problems of long time consumption, low dispensing efficiency, and easy errors, which lead to poor product quality. When a certain dispensing valve has an abnormality during the dispensing operation, the operation information of the dispensing product can be latched, and glue can be filled based on the glue filling operation parameters of the abnormal dispensing valve through the normally working dispensing valve, thereby improving the glue filling efficiency, reducing labor costs, and improving the product yield.

[0043] Example 2 The difference between the embodiment of the present application and the embodiment 1 is that, based on the coordinate position of the abnormal dispensing valve and the coordinate position of the dispensing valve for filling glue, the operation coordinate correction of the filling operation parameters of the product to be filled glue further includes the following steps: Each Z-axis mounting assembly of the third driving mechanism 33 is equipped with a fine-tuning mechanism, the adjustment direction of the fine-tuning mechanism is consistent with the driving direction of the second driving mechanism 32, and the dispensing valve is installed on the fine-tuning mechanism. The set fine-tuning mechanism can realize the synchronous and asynchronous operation of each dispensing valve on the dispensing product.

[0044] The coordinate positions of the abnormal dispensing valve and the glue replenishing dispensing valve in the first direction and the second direction are obtained, the angle formed by the straight line formed by the two coordinate positions and the first driving mechanism 31 is determined, and the coordinate difference and angle between the abnormal dispensing valve and the glue replenishing dispensing valve in the first direction and the second direction are calculated, and the operation coordinates of the glue replenishing dispensing valve moving to the area to be glued are corrected according to the coordinate difference and the angle. This embodiment can realize the correction of the operation coordinates of the glue replenishing operation parameters in the first direction and the second direction (X direction and Y direction) of the glue replenishing product, and further improve the accuracy of the operation in the area to be glued.

[0045] It should be noted that when the driving direction of the second driving mechanism 32 is the X direction, the adjustment direction of the fine adjustment mechanism is the X direction; when the driving direction of the second driving mechanism 32 is the Y direction, the adjustment direction of the fine adjustment mechanism is the Y direction.

[0046] Example 3 The difference between the embodiment of the present application and the embodiment 1 or the embodiment 2 is that, based on the coordinate position of the abnormal dispensing valve and the coordinate position of the glue dispensing valve, the operation coordinate correction of the glue filling operation parameters of the glue filling product further includes the following steps: According to the tool setting height difference between the abnormal dispensing valve and the glue replenishing dispensing valve, the coordinate value of the glue replenishing operation parameter of the glue replenishing dispensing valve in the Z direction is corrected to ensure that the height between the abnormal dispensing valve and the glue replenishing dispensing valve is consistent. This embodiment can realize the operation coordinate correction of the glue replenishing operation parameter of the glue replenishing product in the first direction and the third direction (X direction and Z direction) or the first direction, the second direction and the third direction (X, Y, Z three directions).

[0047] Further, the number of dispensing valves is four as an example for further explanation. Figure 2 As shown, taking the first driving mechanism 31 as an X-direction driving mechanism and the second driving mechanism as a Y-direction driving mechanism as an example, four third driving mechanisms 33 are slidably arranged on the first driving mechanism 31, and the third driving mechanism 33 is a Z-direction driving mechanism, and each third driving mechanism 33 includes: a Y-axis fine-tuning mechanism and a Z-axis dispensing mechanism. The Y-axis fine-tuning mechanism is slidably installed on the first driving mechanism 31 and can move along the X direction, the Z-axis dispensing mechanism is installed on the Y-axis fine-tuning mechanism, and the Y-axis fine-tuning mechanism is used to drive the Z-axis dispensing mechanism to move along the Y direction. The Z-axis dispensing mechanism includes: a Z-axis driving module, a Z-axis mounting assembly and a dispensing valve. The Z-axis driving module is connected to the Y-axis fine-tuning mechanism; the Z-axis mounting assembly is connected to the Z-axis driving module, and the Z-axis driving module can drive the Z-axis mounting assembly to move along the Z direction; the dispensing valve is installed on the Z-axis mounting assembly.

[0049] Based on the coordinate position of the abnormal dispensing valve and the coordinate position of the glue dispensing valve, the operation coordinate correction of the glue filling operation parameters of the glue filling product includes the following steps: First, the coordinate positions of the abnormal dispensing valve and the glue replenishing dispensing valve in the first direction are obtained, and the coordinate difference between the abnormal dispensing valve and the glue replenishing dispensing valve in the X direction is calculated. According to the coordinate difference, the X-axis operation coordinate of the glue replenishing dispensing valve moving to the glue replenishing area is corrected.

[0050] Secondly, the coordinate positions of the abnormal dispensing valve and the glue replenishing dispensing valve in the first direction and the second direction are obtained, the angle formed by the straight line formed by the two coordinate positions and the first driving mechanism 31 is determined, and the coordinate difference and angle between the abnormal dispensing valve and the glue replenishing dispensing valve in the X direction and the Y direction are calculated, and the Y-axis operating coordinate of the glue replenishing dispensing valve to move to the area to be glued is corrected according to the coordinate difference and the angle.

[0051] Finally, according to the difference in tool setting height between the abnormal dispensing valve and the replenishing dispensing valve, the coordinate value of the replenishing dispensing valve's dispensing operation parameters in the Z direction is corrected, such as: the tool setting height of the abnormal dispensing valve is H1, the tool setting height of the replenishing dispensing valve is H2, the difference in height between the Z-axis drive module of the abnormal dispensing valve and the Z-axis drive module of the replenishing dispensing valve is H1-H2, when the height of the dispensing track point of the abnormal dispensing valve is Z1, switch to the replenishing dispensing valve for dispensing, and the height of the dispensing track point of the replenishing dispensing valve is: Z2=Z1-(H1-H2).
