[0032] The application will be further described below in combination with the drawings and embodiments. In addition, the technical features involved in the different embodiments of the application described below can be combined with each other as long as they do not conflict with each other.

[0033] A control method for full-automatic new energy silicone glue dispensing, which is used for new energy battery fireproof silicone glue dispensing operation, controls the mold to be dispensed to a fixed point position for dispensing, and the dispensing process includes:

[0034] (1) The glue dispensing scheme is automatically or manually determined according to the type of the mold to be dispensed, and the PLC control system calls the stored glue dispensing scheme for glue dispensing;

[0035] (2) Based on the dispensing scheme, the PLC control system calls new energy liquid silicone A glue and new energy liquid silicone B glue and mixes them online in the dispensing arm;

[0036] (3) Based on the dispensing scheme, the PLC control system uses the mixed silicone to dispense the mold;

[0037] (4) The system is reset after dispensing.

[0038] The method described in this application is applicable to, for example... Figure 1 The illustrated fully automated dispensing system enables production control of dispensing processes on an assembly line. The system includes a dispensing platform 100, an automatic feeding unit 200, an automatic dispensing unit 300, and a main unit 400 of a PLC control system. The automatic feeding unit 200, dispensing platform 100, and automatic dispensing unit 300 are all connected to the main unit 400 of the PLC control system. Each of these units receives control signals from the PLC control system and operates accordingly, achieving fully automated control of the dispensing production process. This reduces manual labor, improves dispensing accuracy, and enhances dispensing quality stability.

[0039] The dispensing platform 100 includes a conveyor belt, and the automatic dispensing unit 300 includes a gantry 320, a dispensing arm 330, and a three-axis motion assembly 310. The three-axis motion assembly 310 includes an X-axis assembly, a Y-axis assembly, and a Z-axis assembly. The Z-axis assembly is equipped with a fixed frame, and the dispensing arm 330 is fixed to the fixed frame. The Z-axis assembly is fixed to the Y-axis assembly, and the Y-axis assembly is fixed to the X-axis assembly. The gantry 320 supports and fixes the dispensing arm 330 above the conveyor belt, so that the dispensing arm 330 is supported above the conveyor belt. Driven by the three-axis motion assembly 310, the dispensing arm 330's outlet can perform silicone dispensing at any position above the mold 500.

[0040] In one embodiment, the process of automatically determining the dispensing scheme is as follows:

[0041] Step 1: First, obtain the image information of the mold at the fixed position;

[0042] Step 2: The PLC control system receives the mold image information at the fixed position and determines the mold type corresponding to the mold.

[0043] Step 3: The PLC control system calls the dispensing scheme that matches the mold based on the determined mold type.

[0044] In the embodiment, the mold image information is obtained at the fixed point position, ensuring the certainty of the source of the mold image information, reducing or eliminating errors in the mold image information caused by other objects or light changes, and the PLC control system confirms the dispensing scheme to realize the automation of dispensing scheme selection.

[0045] In the embodiment, the mold image information is obtained by a camera unit on the dispensing arm. When the dispensing arm is in a reset state, the camera unit is above the fixed point position. After the PLC control system receives the mold arrival signal, the PLC control system controls the camera unit to take a picture of the mold at the fixed point position and inputs the mold image information into the PLC control system. The camera unit is fixed on the dispensing arm, and the camera unit can always be in the same position when the dispensing arm is reset. The camera unit is used to take pictures of the mold to ensure the consistency of the shooting position and angle, facilitate the analysis and verification of the mold image information by the PLC control system, reduce the variables in the dispensing process control, and ensure the stable progress of the dispensing process.

[0046] In another embodiment, the dispensing scheme can also be manually selected directly, so that the PLC control system calls the stored dispensing scheme. The diversified calling confirmation mode increases the confirmation backup form and improves the applicability of the device and method.

[0047] In an embodiment, the dispensing scheme includes the type of dispensing mold, the feeding flow rate of each cycle of new energy liquid silicone A glue and new energy liquid silicone B glue, the dispensing scheme of the dispensing ratio of new energy liquid silicone A glue and new energy liquid silicone B glue, the dispensing trajectory of the mixed silicone, the extrusion speed of the silicone, and the amount of the silicone. The present application directly retrieves the corresponding parameter scheme, reduces the parameter setting of the production personnel, reduces the production error, reduces the production time, and improves the dispensing production efficiency. Generally, at least 200 dispensing scheme files can be stored in the PLC control system.

[0048] Different molds 500 often need different dispensing schemes due to differences in shape or specifications, wherein the feeding flow rate of the respective circulation flow feeding of new energy liquid silicone glue A and new energy liquid silicone glue B, the dispensing trajectory of the mixed silicone glue, the extrusion speed of the silicone glue, and the amount of the silicone glue generally correspond to the type of dispensing mold. The dispensing arm 330 is fixed on the three-axis motion assembly 310, and the X-axis assembly, the Y-axis assembly, and the Z-axis assembly enable the dispensing arm 330 to move in any direction in three dimensions. The PLC control system controls the movement of the three-axis motion assembly 310 to change the shape of the silicone glue dispensing on the mold 500, i.e., the silicone glue dispensing trajectory control. The present application has multiple dispensing scheme selection options, which can be used for silicone glue dispensing production on various dispensing molds, and has good applicability. A production line can be used for dispensing operations of different products.

[0049] The dispensing platform 100 has a conveyor belt, and the mold 500 to be dispensed is placed on the conveyor belt and moves linearly with the conveyor belt. In an embodiment, before dispensing, the PLC control system controls the movement of the conveyor belt on the dispensing platform to drive the mold to be dispensed on the conveyor belt to a fixed position. The mold arrival signal is obtained by detecting the photoelectric sensor on the dispensing platform. The photoelectric sensor is arranged at the fixed position. When the conveyor belt moves, the mold to be dispensed on the conveyor belt moves in the direction of the assembly line. When the photoelectric sensor detects the mold, the photoelectric sensor sends a mold arrival signal to the PLC control system. The PLC control system controls the conveyor belt to stop moving, so that the mold to be dispensed stays at the fixed position.

[0050] In an embodiment, the PLC control system is provided with a storage module, and the storage module stores multiple dispensing schemes. One mold corresponds to one dispensing scheme. The PLC control system compares the received mold image information with the stored mold image information, calls the dispensing scheme corresponding to the received mold image information, and sets the control parameters of feeding and dispensing.

[0051] In an embodiment, after the system is started, the new energy liquid silicone A glue and the new energy liquid silicone B glue are respectively and respectively circulated and fed, so that the new energy liquid silicone A glue and the new energy liquid silicone B glue are respectively transported from the corresponding storage barrels to the mixing cavity on the glue dispensing arm, and part of the new energy liquid silicone A glue and part of the new energy liquid silicone B glue required for mixing enter the mixing cavity, and the new energy liquid silicone A glue and the new energy liquid silicone B glue not required for use return to the corresponding storage barrels. The new energy liquid silicone A glue and the new energy liquid silicone B glue respectively flow in the pipeline between the storage barrel of the automatic feeding unit 200 and the glue dispensing arm of the automatic glue dispensing unit 300 to circulate and feed, and the new energy liquid silicone A glue and the new energy liquid silicone B glue are both liquid media with high viscosity. The circulation can effectively improve the flowability of the viscous liquid, reduce its blockage and accumulation in the pipeline or equipment, and ensure the smooth progress of the automatic feeding and glue dispensing production process. At the same time, it can also reduce the wear of the new energy liquid silicone A glue and the new energy liquid silicone B glue on the inner wall of the equipment and the pipeline, which is beneficial to prolong the service life of the equipment and helps to reduce the risk of accumulation and leakage of viscous liquid in the pipeline or equipment, and improve the safety of the production process.

[0052] The mixing cavity is in communication with the feeding passage of the new energy liquid silicone A glue and the feeding passage of the new energy liquid silicone B glue. The flow rate of the new energy liquid silicone A glue in the feeding passage of the new energy liquid silicone A glue is greater than the sampling amount of the A glue sampling pump, and the flow rate of the new energy liquid silicone B glue in the feeding passage of the new energy liquid silicone B glue is greater than the sampling amount of the B glue sampling pump. The unused A glue and B glue respectively circulate in the feeding passages thereof. The flow rate of the new energy liquid silicone A glue in the feeding passage is much greater than the sampling amount required by the A glue sampling pump, which ensures that the A glue sampling pump smoothly completes the set sampling amount and also ensures the circulation of the feeding. Similarly, the flow rate of the new energy liquid silicone B glue in the feeding passage is much greater than the sampling amount required by the B glue sampling pump.

[0053] In the embodiment, the new energy liquid silicone raw materials are the new energy liquid silicone A glue and the new energy liquid silicone B glue, which are both stable liquid media. Separate feeding ensures that the raw material liquid does not condense and ensures continuous automatic supply of the raw material liquid. The circulation feeding feeding mode is stable and facilitates the control of the PLC control system.

[0054] In an embodiment, the PLC control system controls the process of mixing new energy liquid silicone A glue and new energy liquid silicone B glue online: the PLC control system calls out the glue dispensing scheme, according to the glue dispensing scheme, the A glue sampling pump and the B glue sampling pump start working at the same time, the A glue sampling pump draws new energy liquid silicone A glue into the mixing chamber, and the B glue sampling pump draws new energy liquid silicone B glue into the mixing chamber; when the total volume of new energy liquid silicone A glue and new energy liquid silicone B glue reaches the set volume, the A glue sampling pump and the B glue sampling pump stop working at the same time, and then new energy liquid silicone A glue and new energy liquid silicone B glue are stirred and mixed uniformly. In this embodiment, the sampling flow rate ratio of the two kinds of original liquid of A glue and B glue entering the mixing chamber can realize the volume ratio of A glue and B glue sampled in the mixing chamber, realize the control of different proportions of the components of the silicone, and adjusting the proportion of A glue and silicone B glue changes the formula of the silicone. Different formula silicones have different viscosities, which can meet the sealing requirements of parts with different design structures.

The starting glue dispensing position setting and the glue dispensing arm resetting facilitate the control cycle of the PLC control system control, facilitate the glue dispensing production of the next mold to be dispensed, realize the flow production, and improve the production efficiency.

[0056] In an embodiment, the PLC control system is provided with a data analysis module, the data analysis module receives the photoelectric sensing and / or magnetic sensing sensor information on the glue dispensing equipment, processes and analyzes the received signals, obtains the equipment state information, and then the data analysis module stores the equipment state information to the storage module or transmits it to the network cloud end, forms an Internet of Things network, so as to realize the remote monitoring of the equipment; the data analysis module records the production information of the new energy battery fireproof silicone glue dispensing operation, and the production information includes production time, output, calling record of the glue dispensing scheme and user information.
