[0034] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 5 .

[0035] A device for detecting the fluidity of droplets on the surface of a nano self-cleaning aluminum curtain plate comprises a detection frame 1 and a manipulator 2 arranged on one side of the detection frame 1 and used to clamp and move the aluminum curtain plate coated with a nano layer. Specifically, the detection frame 1 is fixed on a site through a frame body, and a base of the manipulator 2 is fixed on one side of the detection frame 1, and the detection frame 1 is within the activity radius of the manipulator 2. The manipulator 2 is an intelligent manipulator, and 6 or even more axial activities can be achieved through a controller.

[0036] The detection frame 1 includes an upper base plate 11 and two side plates 12, and the two side plates 12 are formed by vertically extending the upper base plate 11 downward on both sides. The upper base plate 11 is fixed to the frame body by bolts to achieve the fixed setting of the entire detection frame 1; a detection box 101 is rotatably set on the detection frame 1, and rotating shafts 105 are symmetrically set on the outer side walls on both sides of the detection box 101. The rotating shafts 105 are rotatably set to penetrate the two side plates 12 of the detection box 101.

[0037] The detection box 101 includes an opening 102 adapted to the shape of the aluminum curtain plate and an inner sealing plate 13. The inner sealing plate 13 is provided with a plurality of nozzles 103 for uniformly spraying colored charged droplets toward the opening 102. The surface of the aluminum curtain plate is matched with the opening 102 and faces the side of the nozzle 103, so that the nozzle 103 can spray droplets on the surface of the aluminum curtain plate.

[0038] The robot 2 is provided with a suction cup assembly 201 which can absorb the back of the aluminum curtain plate. Figure 1 As shown, the suction cup assembly 201 is composed of a plurality of suction cups. When in use, the suction cup assembly 201 on the manipulator 2 adsorbs the back side of the aluminum curtain plate, and then the front side of the aluminum curtain plate is buckled into the opening 102 of the detection box 101 by controlling the manipulator 2, so that the surface of the aluminum curtain plate is within the spraying range of the nozzle 103.

[0039] A high-voltage electrode (corona discharge method) can be installed near the nozzle 103, or the droplets sprayed from the nozzle can be charged by various existing means such as the jet ionization method. The sprayed droplets have a single polarity charge, such as positively charged droplets or negatively charged droplets. The detection box 101 is provided with an electrode member 104 for energizing the aluminum curtain plate. The electrode polarity of the aluminum curtain plate after energization is opposite to the polarity of the droplet charge, that is, if the droplet has a negative charge, the electrode member 104 is a positive electrode, and the aluminum curtain plate becomes a positive electrode plate after energization, and vice versa.

[0040] When in use, the aluminum curtain plate is buckled at the opening 102 by the manipulator 2, so that the detection box 101 is relatively Figure 1The state shown is in a horizontal state after rotating 90° counterclockwise. Then the aluminum curtain is powered on, and the nozzle 103 sprays droplets evenly onto the surface of the aluminum curtain. The droplets are evenly adsorbed on the surface of the aluminum curtain through the charge adsorption effect. After the nozzle 103 sprays droplets quantitatively, the spraying stops. Then the manipulator 2 drives the aluminum curtain and the detection box 101 to synchronously reverse 90° to present a horizontal state. Figure 1 The vertical state is shown, and then the motor component 104 is powered off, and the droplets fall by their own weight. The operator regularly observes the falling state of the droplets on the aluminum curtain plate surface to preliminarily judge the fluidity of the droplets on the aluminum curtain plate surface.

[0041] In order to realize the automatic on and off of the electrode member 104 when the detection box 101 rotates, the detection box 101 is rotatably provided with a rotating member 106 for fixing the electrode member 104. The rotating member 106 is rotatably arranged on a side wall of the detection box 101 through a pin rod. Figure 2 As shown, the upper end of the rotating member 106 is fixed with an electrode member 104, and the lower end is provided with a driving rod 107 that cooperates with the detection frame 1, and a tension spring 109 is provided between the driving rod 107 and the side wall of the detection box 101 away from the opening 102. One or more conductive contact blocks 4 are provided on the aluminum curtain plate, and the conductive contact blocks 4 can contact with the electrode member 104 after the detection box 101 rotates, so that the aluminum curtain plate is always in a powered state during the rotation process and the horizontal droplet spraying process, so that the droplets can be continuously adsorbed on the surface of the aluminum curtain plate.

[0042] The detection frame 1 is provided with a protrusion 108 that abuts against the driving rod 107 when the detection box 101 is in a vertical state. Specifically, the protrusion 108 is arranged at the edge of the side plate 12. The lower end of the side plate 12 is an arc surface. The side of the arc surface close to the opening 102 is provided with a protrusion 108. When the detection box 101 is in a vertical state, the driving rod 107 abuts against the protrusion 108, so that the rotating member 106 moves along Figure 2 or Figure 5 In the state shown, the electrode member 104 is rotated counterclockwise to keep away from the conductive contact block 4 on the aluminum curtain plate, so that the aluminum curtain plate is in a power-off state, that is, when the aluminum curtain plate is buckled on the detection box 101 and is in a vertical state, the aluminum curtain plate is in a power-off state. At this time, the charged droplets adsorbed by the aluminum curtain plate when it is powered on are no longer adsorbed, and thus slide vertically along the surface due to their own weight. After sliding down, the aluminum curtain plate can be taken out for preliminary observation.

[0043] In order to further detect the fluidity of the droplets on the aluminum curtain plate surface, a droplet collecting unit 3 is provided at the bottom of the detection box 101; the droplet collecting unit includes an inclined collecting tank 301 and a collecting pipe 302 connected to the collecting tank 301; Figure 3 and Figure 4As shown, the collecting tank 301 is inclined from right to left toward one end of the collecting tube 302. A liquid level detection switch 303 is provided at the upper end of the collecting tube 302, and an electromagnetic leakage valve 304 is provided at the lower end. That is, when the electromagnetic leakage valve 304 is initially in a closed state, the liquid droplets pass through the collecting tank 301 and flow into the collecting tube 302 along the inclined surface of the collecting tank 301. When the liquid level rises to the contact position with the liquid level detection switch 303, it is detected by the controller.

[0044] In order to improve the fluidity of the droplets in the collection tank 301, the inner surface of the collection tank 301 is a smooth surface, and its flow resistance can be ignored. An air blowing pipe 305 is provided at one end of the collection tank 301 away from the collection tube 302 to increase the flow speed and cleaning speed of the droplets in the collection tank 301, and ensure that the droplets flowing into the collection tank 301 quickly fall into the collection tube 302 for collection.

[0045] The surface of the protrusion 108 is provided with a timing switch 110 which can be touched by the driving rod 107, that is, when the driving rod 107 touches the protrusion 108, the timing switch 110 can be touched at the same time, that is, when the electrode 104 is out of contact with the aluminum curtain plate, the timing switch 110 is activated; the timing switch 110 is coupled to the liquid level detection switch 303 through the controller, and when the timing switch 110 is activated, the timing starts, at this time, the liquid droplets on the surface of the aluminum curtain plate flow downward into the collection tank 301 by gravity, and then are quickly blown into the collection pipe 302 through the blowing pipe 305, and the liquid level in the collection pipe 302 rises, and when it reaches the liquid level detection switch 303, the information is fed back to the controller, and the controller records the time required for the liquid level to reach the liquid level detection switch 303, and judges the fluidity speed of the liquid droplets on the surface of the aluminum curtain plate according to the collection time, that is, the shorter the collection time, the better the fluidity of the liquid droplets on the surface of the aluminum curtain plate and the faster the flow speed.

[0046] In this embodiment, the controller can be simply controlled by a host computer or a PLC controller, and connected in series with the control system of the robot 2 module to achieve automatic control of the entire equipment, and cooperate with the robot 2 to perform timed and quantitative detection of the aluminum curtain panels on the assembly line, thereby improving the detection efficiency of the aluminum curtain panels.

[0047] A detection process for detecting the fluidity of liquid droplets on the surface of a nano self-cleaning aluminum curtain plate by a device for detecting the fluidity of liquid droplets, the process is as follows:

[0048] S1: The aluminum curtain plate coated with the nano-layer is clamped by the robot 2 and placed in the detection box 101 and fastened to the opening 102;

[0049] S2: The detection box 101 is rotated 90° relative to the detection frame 1 to a horizontal state by moving the manipulator 2. During the rotation, the driving rod 107 is disengaged from the protrusion 108, and the rotating member 106 is rotated under the action of the tension spring 109 so that the electrode member 104 contacts the conductive contact block 4 of the aluminum curtain plate and then energizes. When the detection box 101 and the aluminum curtain plate are rotated synchronously to a horizontal state, the nozzle 103 quantitatively sprays colored charged droplets, and the aluminum curtain plate has an electrode with a polarity opposite to that of the droplets when the electrode member 104 is energized, and the charged droplets are uniformly adsorbed on the surface of the aluminum curtain plate.

[0050] S3: The surface of the aluminum curtain plate uniformly absorbs the charged colored droplets through the electrode polarity. After the nozzle 103 sprays a certain amount of droplets, the detection box 101 is placed in a vertical state under the drive of the robot 2;

[0051] S4: The protrusion 108 and the driving rod 107 touch each other again, so that the rotating member 106 overcomes the resistance of the tension spring 109 and rotates. At this time, the electrode member 104 is separated from the aluminum curtain plate, and the timing switch 110 is triggered to start timing. Since the aluminum curtain plate is not charged after the electrode member 104 is separated from the aluminum curtain plate, the liquid droplets slide freely vertically along the surface of the aluminum curtain plate due to their own weight, forming flow traces of the liquid droplets on the surface of the aluminum curtain plate.

[0052] S5: After taking the aluminum curtain plate out of the detection box 101, observe the distribution and flow of the colored droplets on the surface, and preliminarily judge the surface fluidity and uniformity of the aluminum curtain plate.

[0053] S6: In the process of S4, the falling droplets fall into the collection tank 301 and are quickly blown into the collection tube 302 through the blowing tube 305. The liquid level in the collection tube 302 rises. When it reaches the liquid level detection switch 303, the information is fed back to the controller. The controller records the time required for the liquid level to reach the liquid level detection switch 303, and determines the flow speed of the droplets on the surface of the aluminum curtain plate according to the collection time. That is, the shorter the collection time, the better the flow speed of the droplets on the surface of the aluminum curtain plate and the faster the flow speed.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
