Description

Technical Field

[0001] The utility model relates to the technical field of heating devices for gluing equipment, in particular to a mobile heating device for gluing equipment. Background Art

[0002] In China, due to the application of industrial robots, some welding and gluing workshops have adopted automated glue spraying. However, due to insufficient early experience in automatic industrial glue spraying, the selection of glue spraying equipment cannot meet the requirements of equipment utilization rate. Therefore, an analysis of common failures of glue spraying equipment shows that most of the reasons are that the heating temperature of the glue spraying equipment cannot meet the process setting requirements, and it is impossible to ensure that the glue has good fluidity. In addition, during the glue spraying process, the equipment error affects the equipment utilization rate. For example, when a certain station process requires a large flow rate of glue spraying per unit time, the dynamic viscosity of the glue inside the glue cylinder is high and the kinematic viscosity is low. When the dosing machine motor drives the piston rod to move, it is unable to squeeze out the glue, resulting in an increase in pressure inside the glue cylinder. At the same time, the feedback pressure of the dosing machine motor increases and exceeds its own threshold, and the equipment will fail. In order to improve this situation, one option is to re-purchase glue coating equipment with heating function, and the other option is to independently improve and design a mobile glue coating heating device for installation to improve the kinematic viscosity of the glue. However, re-purchasing glue coating equipment with heating function is expensive and has a long cycle. Therefore, it is necessary to use components such as thermostats, electromagnetic contactors and fuses to develop a glue coating heating device with extremely high cost performance, which can be installed and disassembled at any time.

[0003] At present, although there are temperature control devices or temperature control systems, or devices with simple temperature heating, these temperature control devices or temperature control systems cannot guarantee that the heating circuit will be disconnected when the thermostat fails, and are not suitable for environments with extremely high integration of industrial robots. Therefore, those skilled in the art provide a mobile heating device for gluing equipment to solve the problems raised in the above background technology. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The present invention provides an embodiment of a mobile heating device for glue coating equipment, comprising an electrical box control cabinet and a switch 4, a distributor 8, a temperature fuse 10 on the L side, a temperature fuse 12 on the R side, a heating tape 15 for the glue barrel, and a thermocouple 16. A main circuit breaker 6 is fixedly installed on the upper side of the inner wall behind the electrical box control cabinet and the switch 4, and twelve branch circuit breakers 7 are fixedly installed on the upper side of the middle of the inner wall behind the electrical box control cabinet and the switch 4.

[0025] Six L-side electromagnetic contactors 9 are fixedly installed in the middle position of the inner wall behind the electrical box control cabinet and the switch 4, and six R-side electromagnetic contactors 11 are fixedly installed in the lower position of the middle of the inner wall behind the electrical box control cabinet and the switch 4. The rubber barrel heating tape 15 and the thermocouple 16 are connected through a cable connector 14.

[0026] A power indicator light 1 is fixedly provided in the middle upper position of the front end face of the electrical box control cabinet and the switch 4, twelve temperature controllers 2 are fixedly provided in the middle position of the upper position of the front end face of the electrical box control cabinet and the switch 4, and the twelve temperature controllers 2 are connected to thermocouples 16, twelve two-speed knob switches 3 are rotatably provided in the middle position of the lower side of the front end face of the electrical box control cabinet and the switch 4, twelve cable quick-connect connectors 5 are fixedly provided on one end face of the electrical box control cabinet and the switch 4, a splitter 8 is fixedly provided on one side of the upper side of the inner wall on the rear side of the electrical box control cabinet and the switch 4, and the splitter 8 is provided on one side of the twelve branch circuit breakers 7.

[0027] The L-side temperature fuse 10 is fixedly set on one side of the middle of the rear inner wall of the electrical box control cabinet and the switch 4. The L-side temperature fuse 10 is set on one side of the six L-side electromagnetic contactors 9. The R-side temperature fuse 12 is fixedly set on one side of the lower side of the rear inner wall of the electrical box control cabinet and the switch 4. The R-side temperature fuse 12 is set on one side of the six R-side electromagnetic contactors 11. Both ends of the rubber barrel heating cable 15 are connected to the power line through cable connectors 14. A cable groove 13 is opened on the front surface of the electrical box control cabinet and the switch 4.

[0028] Specifically, the device requires an external 220V power supply, which is connected to the main circuit breaker 6, and then the power is divided into each branch circuit breaker 7 through the splitter 8. The branch circuit breakers 7 are then connected to the power input end of the temperature controller 2 and the high voltage input end of the electromagnetic contactor through cables. At the same time, the output end of the temperature controller 2 is connected to the control input end of the electromagnetic contactor to control the action of the electromagnetic contactor, and the high voltage output port of the electromagnetic contactor is connected to one end of the temperature circuit breaker. The other end of the temperature circuit breaker is output to the wiring quick plug connector. At the same time, the temperature controller 2 is connected to the power input end of the temperature controller 2 and the high voltage input end of the electromagnetic contactor to control the action of the electromagnetic contactor. The control output end of the controller 2 is connected to the cable of the thermocouple 16 and is also connected to the wiring quick-plug connector. The power cord and the temperature control cable are integrated into the output port of the control cabinet, and the transition is made through the cable quick-plug connector 5. The power cord is connected to the two ends of the glue barrel heating heating tape 15 through the cable connector 14, and the temperature control line is connected to the thermocouple 16 to detect the temperature of the heating heating tape, thereby realizing real-time monitoring, feedback and adjustment of the temperature, more conveniently ensuring the fluidity of the glue, reducing the probability of equipment failure caused by the low kinematic viscosity of the glue, and thus improving the start-up rate of the glue coating equipment.

[0029] The temperature controller 2 outputs a heating on or off instruction to control the action of the electromagnetic contactor, and then controls the operation of the heating heating tape. It uses low-voltage weak electricity to control the input of the heating power supply to each heating heating tape, ensuring the safe use of electricity for the equipment. In order to prevent overload or short circuit in the heating circuit, each channel branch is installed with an air switch circuit breaker, and the main trunk is still installed with an air switch circuit breaker at the same time, thereby ensuring the safe use of electricity for the equipment. The temperature controller 2 has a highly sensitive PID adjustment function and a high-temperature alarm function, which can adjust the heating temperature of the glue barrel, filter, hose and gun head of the glue coating equipment. The internal structure of the temperature control collects the temperature signal of the thermocouple 16 and performs real-time control. If the maximum set temperature is exceeded, the temperature controller will disconnect the output heating instruction to prevent the heating temperature from being too high and causing the glue to deteriorate.

[0030] The temperature fuse is installed between the electromagnetic contactor and the quick-connect connector on the side of the electrical box. It prevents the heating temperature from being too high and damaging the quality of the glue due to a short circuit in the heating tape at a certain position such as the glue barrel, filter, hose and gun head, or failure of the temperature controller 2. Combined with the alarm function of the temperature controller 2 itself, this temperature fuse plays a secondary protection role in preventing the glue from being damaged. If the heating temperature of the gluing equipment cannot meet the process setting requirements, the glue cannot be guaranteed to have good fluidity, and the equipment error during the gluing process affects the equipment start-up rate, the device of the utility model can be installed to improve the fluidity of the glue, which is more cost-effective than replacing the process equipment.

[0031] Working principle: The heating device of the dual-channel glue coating equipment includes an electrical box control cabinet with a safety grade of IP54 made of stainless steel material. A power indicator light 1, twelve control start knobs and a temperature controller 2 are installed in front of the cabinet door. A power cord and a cable quick-connect connector 5 with integrated thermocouple 16 cables are installed on the side of the electrical box control cabinet. The electrical box control cabinet is equipped with a main circuit breaker 6, twelve branch circuit breakers 7, a distributor 8, six L-side electromagnetic contactors 9 and corresponding six L-side temperature fuses 10, six R-side electromagnetic contactors 11 and corresponding six R-side temperature fuses 12, and the internal cable routing is distributed and installed through wiring troughs.

[0032] Secondly, the installation of each component is clipped into the electrical box control cabinet through a dedicated guide rail, and the connection of the components is installed and wired through cables of different square sizes. The heating power line and thermocouple 16 line of the integrated channel of the cable quick connector 5 installed on the side of the electrical box control cabinet are connected to the heating heating tape and thermocouple 16 through the cable connector 14.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
