[0068] Please refer to Figure 1 , Figure 1 The structure of the coating system 10 provided by some embodiments of the present application is shown in the schematic diagram. The embodiment of the present application provides a coating system 10. The coating system 10 comprises a plurality of coating heads 11 and a plurality of discharge mechanisms 12. The discharge mechanisms 12 and the coating heads 11 correspond to each other. The discharge mechanisms 12 are used to control the discharge of the coating heads 11.

[0069] The coating head 11 is a discharge structure for the paint 30 to flow out of the coating system 10 and adhere to the workpiece 20. The discharge mechanism 12 is a structure for controlling the discharge of the coating head 11.

[0070] The coating system 10 can comprise two coating heads 11, three coating heads 11 or more than three coating heads 11. Correspondingly, the number of discharge mechanisms 12 is two, three or more than three. That is, when the coating system 10 comprises two coating heads 11, the number of discharge mechanisms 12 is also two. When the coating system 10 comprises three coating heads 11, the number of discharge mechanisms 12 is also three. The number of discharge mechanisms 12 is equal to the number of coating heads 11. One discharge mechanism 12 corresponds to and controls the discharge of one coating head 11.

[0071] The coating system 10 is provided with a plurality of coating heads 11 and a plurality of discharge mechanisms 12, one discharge mechanism 12 corresponding to one coating head 11 to control the discharge of the coating head 11, and some discharge mechanisms 12 can be selectively opened to control the discharge of the corresponding coating heads 11, so as to form different coating tracks on the surface of the workpiece 20 to be coated, and different models of workpieces 20 can be quickly changed, and the adaptability is strong.

[0072] Please refer to Figure 1 and Figure 2 , Figure 2 The schematic block diagram of the coating system 10 provided by some embodiments of the present application is shown. In some embodiments, the discharge mechanism 12 includes a switching device 121 connected with the coating head 11, and the switching device 121 is used to open or close the coating head 11.

[0073] The switching device 121 generally has an open state and a closed state, when the switching device 121 is in the open state, the coating head 11 discharges. When the switching device 121 is closed, the coating head 11 stops discharging. The switching device 121 can be various valve bodies, such as electric valve, hydraulic valve, pneumatic valve, etc.

[0074] The switching device 121 controls whether the coating head 11 discharges, which is simple and convenient, and low in cost.

[0075] Please refer to Figure 1 and Figure 2 In some embodiments, the coating system 10 further includes a first controller 13 connected with the switching devices 121 of the plurality of discharge mechanisms 12. The first controller 13 is used to control the switching devices 121 to open or close.

[0076] The first controller 13 is a processing unit with information processing and program running functions, such as CPU (central processing unit), PLC (Programmable Logic Controller) and ECU (Electronic Control Unit), etc. The first controller 13 can be electrically connected with the switching devices 121 of the plurality of discharge mechanisms 12 to open or close the discharge mechanisms 12 as needed.

[0077] The first controller 13 can control the switching devices 121 of the plurality of discharge mechanisms 12 to open or close, so that the first controller 13 can selectively open some switching devices 121 as needed to control the discharge of the corresponding coating heads 11, so as to form different coating tracks on the surface of the workpiece 20 to be coated, and different models of workpieces 20 can be quickly changed, and the adaptability is strong.

[0078] In some embodiments, the switch device 121 comprises a solenoid valve.

[0079] In one aspect, the solenoid valve can well control whether the coating head 11 discharges or not, and has high stability. In another aspect, the solenoid valve has low cost, which is conducive to reducing the cost of the coating system 10. In addition, the solenoid valve is easy to be linked with the first controller 13, and is opened or closed under the control of the first controller 13.

[0080] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 3 a schematic block diagram of the coating system 10 provided by some embodiments of the present application. In some embodiments, the coating system 10 further comprises a feeding mechanism 14, which is connected with the coating head 11 through the switch device 121. The switch device 121 is configured to connect or disconnect the feeding mechanism 14 and the coating head 11.

[0081] The feeding mechanism 14 is a mechanism for providing the coating head 11 with the coating 30. The coating system 10 further comprises a first pipe 124 and a second pipe 125, wherein the first pipe 124 connects the outlet end of the switch device 121 and the coating head 11, and the second pipe 125 connects the inlet end of the switch device 121 and the feeding mechanism 14, that is, the feeding mechanism 14 is connected with the coating head 11 through the switch device 121.

When the switch device 121 is closed, the switch device 121 disconnects the feeding mechanism 14 and the coating head 11, and the feeding mechanism 14 cannot supply the coating 30 to the coating head 11, and the coating head 11 stops discharging.

[0083] Please refer to Figure 4 and Figure 5 , Figure 4 a schematic structural diagram of the coating system 10 before coating provided by some embodiments of the present application. Figure 5 a schematic structural diagram of the coating system 10 after coating provided by some embodiments of the present application. In use of the coating system 10 provided by the embodiments of the present application, according to different needs, the first controller 13 controls at least part of the plurality of discharge mechanisms 12 to be opened, so that the feeding mechanism 14 is connected with the coating head 11, the feeding mechanism 14 supplies the coating 30 to the coating head 11, the coating 30 flows out from the corresponding coating heads 11 and adheres to the workpiece 20, so as to form the required coating track. When different models of workpieces 20 are replaced, the first controller 13 can selectively control some discharge mechanisms 12 to be opened, so as to form different coating tracks.

[0084] Please refer toFigure 6 、 Figure 7 and Figure 8 , Figure 6 is a front structural schematic diagram of the coating system 10 provided by some embodiments of the present application. Figure 7 is a back structural schematic diagram of the coating system 10 provided by some embodiments of the present application. Figure 8 is a structural schematic diagram of the material storage member 15 provided by some embodiments of the present application. In some embodiments, the coating system 10 comprises the material storage member 15, and a plurality of material storage cavities 151 are formed inside the material storage member 15. The discharging mechanism 12 comprises extruding members, and the extruding members correspond to the material storage cavities 151 one by one. The extruding members are connected to the material storage member 15, and the coating head 11 is in communication with the material storage cavities 151. The extruding members are used to extrude the coating material 30 in the material storage cavities 151 to the coating head 11, so as to discharge the coating head 11.

[0085] The material storage member 15 is internally formed with a plurality of material storage cavities 151, and the material storage cavities 151 are used to store the coating material 30. The plurality of material storage cavities 151 are independent of each other and are not in communication with each other.

[0086] The extruding member is a structure capable of changing the size of the space between the extruding member and the coating head 11. When one discharging mechanism 12 is provided with one extruding member, the number of the material storage cavities 151 is the same as the number of the discharging mechanisms 12. For example, when the coating system 10 comprises two discharging mechanisms 12, the number of the extruding members is two, and the number of the material storage cavities 151 is also two. When the coating system 10 comprises three discharging mechanisms 12, the number of the extruding members is three, and the number of the material storage cavities 151 is also three.

[0087] It should be noted that, here, the number of the material storage cavities 151 is the same as the number of the discharging mechanisms 12, which means that the total number of the material storage cavities 151 is the same as the total number of the discharging mechanisms 12, rather than the number of the material storage cavities 151 possessed by one material storage member 15 is the same as the number of the discharging mechanisms 12. For example, when the coating system 10 comprises four discharging mechanisms 12, the number of the extruding members is four, one material storage member 15 can comprise two material storage cavities 151, and the coating system 10 can be provided with two material storage members 15, so that the total number of the material storage cavities 151 is four.

[0088] By pushing and extruding the coating material 30 in the material storage cavities 151 through the extruding members, the coating material 30 can be moved to the coating head 11 and discharged from the coating head 11, so as to realize discharging. In this way, the discharging speed of the coating head 11 can be adjusted by adjusting the extruding speed of the extruding members, so as to further improve the adaptability of the coating system 10.

[0089] Please refer to Figure 6 , Figure 7 , Figure 8 and Figure 9 , Figure 9A schematic block diagram of the coating system 10 is provided for some embodiments of the present application. In some embodiments, the extruding member comprises a cylinder 122, and a piston rod of the cylinder 122 is movably arranged in the storage cavity 151.

[0090] When the cylinder 122 is elongated, the piston rod of the cylinder 122 moves towards the coating head 11, and the coating 30 in the storage cavity 151 can be extruded towards the coating head 11, so that the coating head 11 discharges. When the cylinder 122 is shortened, the piston rod of the cylinder 122 moves away from the coating head 11, so that the space between the piston rod of the cylinder 122 and the coating head 11 is increased, and the coating 30 can be replenished in the space. In addition, the discharge speed of the coating head 11 can be adjusted by adjusting the elongation speed of the cylinder 122, so as to improve the adaptability of the coating system 10.

[0091] Please refer to Figure 6 , Figure 7 , Figure 8 and Figure 9 In some embodiments, the coating system 10 further comprises a second controller 16, and the second controller 16 is connected with the cylinders 122 of the plurality of discharge mechanisms 12, and the second controller 16 is used to control the cylinders 122 to be elongated or shortened.

[0092] The second controller 16 is a processing unit with information processing and program running functions, such as a CPU (central processing unit), a PLC (Programmable Logic Controller) and an ECU (Electronic Control Unit), etc. The second controller 16 can be electrically connected with the cylinders 122 of the plurality of discharge mechanisms 12, so as to control the cylinders 122 to be elongated or shortened as needed.

[0093] The second controller 16 can control the cylinders 122 of the plurality of discharge mechanisms 12 to be elongated or shortened, so that the second controller 16 can selectively control some of the cylinders 122 to be elongated as needed, so as to control some of the coating heads 11 to discharge, and different coating tracks can be formed on the surface of the workpiece 20 to be coated, and different models of workpieces 20 can be quickly changed, and the adaptability is strong.

[0094] Please refer to Figure 6 , Figure 7 , Figure 8 and Figure 10 , Figure 10 A schematic block diagram of the coating system 10 is provided for some embodiments of the present application. In some embodiments, the extruding member comprises a piezoelectric crystal 123, and the piezoelectric crystal 123 is arranged in the storage cavity 151.

[0095] Piezoelectric crystal 123 refers to a non-centrosymmetric crystal that produces deformation under mechanical force, causing the relative displacement of charged particles, thereby generating positive and negative bound charges on the surface of the crystal.

[0096] When a voltage is applied to the piezoelectric crystal 123, the piezoelectric crystal 123 will deform, thereby extruding the paint 30 in the storage cavity 151 to the coating head 11, realizing the discharging of the coating head 11.

[0097] Please refer to Figure 6 , Figure 7 , Figure 8 and Figure 10 In some embodiments, the coating system 10 further comprises a third controller 17 connected to the piezoelectric crystals 123 of the plurality of discharging mechanisms 12, and the third controller 17 is used to control the on-off of the piezoelectric crystals 123.
