Description

Technical Field

[0001] The present invention relates to the technical field of valve island control, and in particular to a multi-suction nozzle valve island control system. Background Art

[0002] During the assembly or testing of electronic products, there are many small parts of electronic products that need to be quickly picked up and placed. The structures for picking up and placing these parts mostly use assemblies composed of cylinders and vacuum nozzles, and each cylinder and vacuum nozzle must be equipped with independent valves and air circuits. When multiple sets of assemblies composed of cylinders and vacuum nozzles are needed for picking and placing operations, the number of valves and air circuits used is relatively large, and it is easy for valves and air pipes to be placed in a messy manner, which will cause the volume of multiple sets of assemblies to be too large, not only taking up more production space, but also inconvenient for maintenance. Summary of the invention

[0003] The purpose of the present invention is to design a multi-nozzle valve island control system so as to solve the problems mentioned in the background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

The cylinder air circuit assembly is provided with several and matched and connected with the input end of the cylinder, and the nozzle air circuit assembly is provided with several and matched and connected with the input end of the nozzle, and the cylinder air circuit assembly and the nozzle air circuit assembly are both electrically connected to the controller.

[0006] Furthermore, the cylinder air circuit assembly includes a first proportional valve, a second proportional valve and a first solenoid valve electrically connected to the controller, the first proportional valve, the first solenoid valve and the input end of the cylinder are connected in sequence, and the second proportional valve is connected to the input end of the cylinder.

[0007] Furthermore, an ascending speed regulating valve and a descending speed regulating valve electrically connected to the controller are connected in sequence between the first solenoid valve and the input end of the cylinder.

[0011] Furthermore, the suction nozzle is connected to a vacuum sensor electrically connected to the controller.

[0012] Furthermore, a safety valve electrically connected to the controller is installed on the suction nozzle.

[0013] Furthermore, an exhaust muffler is installed on the valve island base.

[0014] Furthermore, the number of the cylinders is 35.

[0015] The beneficial effects of the present invention are:

[0023] like Figure 1 As shown, a multi-nozzle valve island control system includes a valve island base and 35 cylinders 1, a nozzle 2 is installed at the output end of the cylinder 1, a controller, a cylinder air circuit assembly and a nozzle air circuit assembly are arranged inside the valve island base, the controller is a PLC controller, 35 cylinder air circuit assemblies are provided and matched with the input end of the cylinder 1, 35 nozzle air circuit assemblies are provided and matched with the input end of the nozzle 2, and the cylinder air circuit assembly and the nozzle air circuit assembly are both electrically connected to the controller;

[0024] The cylinder gas circuit assembly includes a first proportional valve 3, a second proportional valve 4, a first solenoid valve 5, an ascending speed regulating valve 6 and a descending speed regulating valve 7 which are electrically connected to the controller. The first proportional valve 3, the first solenoid valve 5, the ascending speed regulating valve 6, the descending speed regulating valve 7 and the input end of the cylinder 1 are connected in sequence, and the second proportional valve 4 is connected to the input end of the cylinder 1. The first proportional valve 3 is used to control the descending air pressure of the cylinder 1, and the second proportional valve 4 is used to control the ascending air pressure of the cylinder 1. The first solenoid valve 5 is used to control the descent of the cylinder 1. The ascending speed regulating valve 6 is used to control the ascending speed of the suction nozzle 2 driven by the cylinder 1 to avoid the parts sucked by the suction nozzle 2 falling due to the too fast ascending; the descending speed regulating valve 7 is used to control the descending speed of the suction nozzle 2 driven by the cylinder 1 to avoid the parts to be sucked by the suction nozzle 2 being crushed due to the too fast descending;

[0025] The nozzle air circuit assembly includes a third proportional valve 8, a fourth proportional valve 9, a second solenoid valve 10, a third solenoid valve 11, a vacuum breaking speed regulating valve 12 and a logic valve 13 which are electrically connected to the controller. The third proportional valve 8, the second solenoid valve 10, the vacuum breaking speed regulating valve 12 and the input end of the nozzle 2 are connected in sequence, and the fourth proportional valve 9, the third solenoid valve 11, the logic valve 13 and the input end of the nozzle 2 are connected in sequence. The third proportional valve 8 is used to control the vacuum breaking air pressure of the nozzle 2, the fourth proportional valve 9 is used to control the vacuum air pressure of the nozzle 2, the second solenoid valve 10 is used for vacuum breaking blowing to prevent the material from sticking to the nozzle 2; the vacuum breaking speed regulating valve 12 is used to control the size of the vacuum breaking blowing, and then control the speed at which the nozzle 2 releases the sucked parts to avoid releasing too quickly and placing the parts unevenly; the logic valve 13 is used to provide a vacuum protection function to prevent a large amount of vacuum leakage when no material is sucked;

[0026] The suction nozzle 2 is connected to a vacuum sensor 14 electrically connected to the controller for determining whether the suction nozzle 2 sucks materials; a safety valve electrically connected to the controller is installed on the suction nozzle 2, and an exhaust muffler is installed on the valve island base for reducing exhaust noise.

[0027] Working principle:

[0028] like Figure 1 As shown, when the multi-nozzle valve island control system is in use, the controller controls 35 cylinder air circuit assemblies and 35 nozzle air circuit assemblies to operate, and then controls a single group or multiple groups of assemblies consisting of cylinder 1 and nozzle 2 to perform pick-up and placement operations. The operation mode of cylinder 1 is that when the first proportional valve 3, the first solenoid valve 5 and the descending speed regulating valve 7 are opened, the output end of cylinder 1 will drive the nozzle 2 to descend, and when the second proportional valve 4 and the ascending speed regulating valve 6 are opened, the output end of cylinder 1 will drive the nozzle 2 to rise; the operation mode of nozzle 2 is that when the fourth proportional valve 9, the third solenoid valve 11 and the logic valve 13 are opened, the nozzle 2 will suck the parts, and when the third proportional valve 8, the second solenoid valve 10 and the vacuum breaking speed regulating valve 12 are opened, the nozzle 2 will release the sucked parts.
