[0003] In order to make up for the shortcomings of the prior art, the utility model provides a paint line centralized control energy-saving device, which controls the start and stop of the conveyor belt through the cooperation of a photoelectric switch and an industrial control board, thereby avoiding the waste of electricity caused by idling of the conveyor belt motor in the prior art.

[0004] The described paint line centralized control energy-saving device includes an industrial control board, at least two conveyor belts and several relays. The input end of the industrial control board is connected to the switching power supply, and the output end is respectively connected to several of the relays, and the output ends of the relays are respectively connected to the conveyor belts one by one; the input end of the industrial control board is also connected to a photoelectric switch and an emergency stop switch, the input end of the photoelectric switch is connected to the switching power supply, and the emergency stop switch controls the disconnection of the relay; the conveyor belts belong to the same product assembly line and are arranged in sequence at intervals. The photoelectric switch sends the received feeding signal to the industrial control board. After the industrial control board receives the feeding signal of the first station conveyor belt, it controls the relays connected to it to be attracted one by one and then start the conveyor belt work in sequence; when the photoelectric switch does not receive the feeding signal of the first station conveyor belt within the set time, the industrial control board controls the relays connected to it to be disconnected step by step, and then shuts down the conveyor belts in sequence.

[0005] Furthermore, the switching power supply is connected to a 220V power line through an air switch, and a start-stop switch is provided on the live wire between the switching power supply and the air switch.

[0006] Furthermore, the number of the relays is the same as the number of the conveyor belts.

[0007] Furthermore, the number of the conveyor belts is ten, which are used in sequence for the transmission of the workpieces to be processed at the left and right brush machine stations, the single roller coating machine station, the front and back brush machine stations, the UV curing machine station I, the coating machine station, the leveling machine station, the UV curing machine station II, the UV curing machine station III, the conveying station and the conveying roller station of the loading robot.

[0008] Furthermore, the output ports of the industrial control board include Y0-Y7, Y10 and Y11, and Y0-Y7, Y10-Y11 are respectively connected to the left and right brush machine stations, the single roller coating machine station, the front and back brush machine stations, the UV curing machine station I, the coating machine station, the leveling machine station, the UV curing machine station II, the UV curing machine station III, the conveying station and the conveying roller station of the manipulator in sequence through ten relays; when the photoelectric switch receives the feeding signal, the industrial control board controls the relays connected to Y0-Y7, Y10-Y11 to be attracted one by one according to the set time; when the photoelectric switch does not receive the photoelectric signal when the set time arrives, the industrial control board controls the relays connected to Y0-Y7, Y10-Y11 to be disconnected step by step, and the conveyor belt stops step by step. If the emergency stop switch (2) is pressed, the ten relays are disconnected immediately.

[0009] Furthermore, the UV curing machine station I and the UV curing machine station II are both three-lamp UV curing machines, and the UV curing machine station III is a six-lamp UV curing machine.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] (1) The device controls the opening and closing of the conveyor belt by cooperating with the photoelectric switch and the industrial control board to control the closing and opening of the relay. After the photoelectric signal receives the feeding signal of the conveyor belt of the first station, the industrial control board controls the relay to close in sequence, and the conveyor belt starts to work in sequence; if the feeding signal is not received within the set time (that is, the time when the adjacent workpiece to be processed enters the first station), the industrial control board controls the relay to disconnect in sequence, and the conveyor belt is shut down in sequence; therefore, the device can centrally control the work of multiple stations on the assembly line, and can shut down the operation of the conveyor belt in time when there is no feeding, avoiding the situation in the prior art where the conveyor belt motor runs idle and causes waste of electricity.

[0016] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the present invention is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1 and Figure 2 As shown, a paint line centralized control energy-saving device includes an industrial control board 1, at least two conveyor belts and a plurality of relays 3. The input end of the industrial control board 1 is connected to a switching power supply 4, and the output end is respectively connected to a plurality of relays 3. The number of relays 3 is consistent with the number of conveyor belts, and the output ends of the relays 3 are respectively connected to the conveyor belts (not shown in the figure) in a one-to-one correspondence; the input end of the industrial control board 1 is also connected to a photoelectric switch 7 and an emergency stop switch 2. The input end of the photoelectric switch 7 is connected to the switching power supply 4, and the emergency stop switch 2 controls the disconnection of the relay 3 (when a problem occurs in production, the equipment can be shut down by pressing the emergency stop switch 2). The conveyor belts belong to the same product assembly line and are arranged in intervals in sequence. The photoelectric switch 7 sends the received feeding signal to the industrial control board 1. After the industrial control board 1 receives the feeding signal of the conveyor belt of the first station, it controls the relays 3 connected thereto to be attracted one by one and then start the conveyor belt work in sequence; when the photoelectric switch 7 does not receive the feeding signal of the conveyor belt of the first station within the set time, the industrial control board 1 controls the relays 3 connected thereto to be disconnected step by step, and then shuts down the conveyor belt in sequence.

[0018] In addition, the switching power supply 4 is connected to the 220V power line through the air switch 5, and a start-stop switch 6 is provided on the live line between the switching power supply 4 and the air switch 5.

[0019] In this embodiment, there are ten conveyor belts, which are used for the transmission of the workpieces to be processed at the left and right brush machine stations, the single roller coating machine station, the front and back brush machine stations, the UV curing machine station I, the coating machine station, the leveling machine station, the UV curing machine station II, the UV curing machine station III, the conveying station and the conveying roller station of the feeding manipulator. Among them, the UV curing machine station I and the UV curing machine station II are both three-lamp UV curing machines, and the UV curing machine station III is a six-lamp UV curing machine.

[0020] The output ports of the industrial control board 1 include Y0-Y7, Y10 and Y11. Y0-Y7 and Y10-Y11 are respectively connected to the conveyor belts of the left and right brush machine stations (first station), the single roller coating machine station (second station), the positive and negative brush machine station (third station), the UV curing machine station I (fourth station), the coating machine station (fifth station), the leveling machine station (sixth station), the UV curing machine station II (seventh station), the UV curing machine station III (eighth station), the conveying station (ninth station) and the conveying roller station (tenth station) of the manipulator in sequence through ten relays 3; when the photoelectric switch 7 receives the feeding signal, the industrial control board 1 controls the relays 3 connected to Y0-Y7 and Y10-Y11 to be successively attracted according to the set time; when the photoelectric switch 7 does not receive the photoelectric signal when the set time is reached, the industrial control board 1 controls the relays 3 connected to Y0-Y7 and Y10-Y11 to be disconnected step by step, and the conveying belt stops step by step.

[0021] It can be understood that the device controls the opening and closing of the conveyor belt by controlling the closing and opening of the relay 3 through the cooperation of the photoelectric switch 7 and the industrial control board 1. After the photoelectric signal 7 receives the feeding signal of the conveyor belt of the first station, the industrial control board 1 controls the relay 3 to be closed in sequence (from the first station to the tenth station), and the conveyor belt starts to work in sequence; if the feeding signal is not received within the set time (that is, the time when the adjacent workpiece to be processed enters the first station), the industrial control board controls the relay to be disconnected step by step in reverse sequence, and the conveyor belt is shut down in sequence; therefore, the device can centrally control the work of multiple stations on the assembly line, and can shut down the operation of the conveyor belt in time when there is no feeding, thereby avoiding the situation in the prior art where the conveyor belt motor runs idle and causes waste of electricity.
