Description

Technical Field

[0001] The present invention relates to the technical field of button dripper production, and particularly to an intelligent test and sorting platform and sorting method for button drippers. Background Art

[0002] The button-type pressure-compensating dripper is one of the common dripper forms in the drip irrigation field. Currently, the commonly used button-type pressure-compensating dripper generally consists of three parts: a housing main body, a silicone compensation sheet, and a housing end cap. Among them, the housing main body and the end cap part are generally made of PE material by injection molding with different molds. The compensation sheet is first injection molded into a sheet by silicone material, then punched into a circular shape by a punching machine, and finally the housing main body, the silicone compensation sheet, and the housing end cap are assembled and formed by an assembly device.

[0003] At present, the flow stability and consistency of button-type pressure-compensating drippers on the market are poor. The factors affecting the flow stability and consistency of pressure-compensating button tube drippers are as follows: First, the mold accuracy for producing the housing main body and the housing end cap is low; second, the manufacturing accuracy of the silicone sheet is low, and the second-stage vulcanization temperature, time, and storage standard of the silicone sheet in the vulcanizer will directly affect the accuracy of the silicone sheet. Therefore, it is very difficult for button-type pressure-compensating drippers to meet the requirements of high flow stability and consistency during production. After years of hard research, the inventor has explored all the factors affecting flow stability thousands of times without much breakthrough. Therefore, the inventor changed the research direction and made a breakthrough in the flow detection of button-type pressure-compensating drippers, and proposed an intelligent test and sorting platform and sorting method for button drippers, which classifies the produced button-type pressure-compensating drippers according to the flow accuracy, and divides them into Class A, Class B, and unqualified products according to the size of the flow deviation. In this way, customers can select different levels of button-type pressure-compensating drippers according to their needs, and screen out unqualified products, improving the flow stability and consistency of the button-type pressure-compensating drippers leaving the factory.

[0064] A method for sorting button droppers by using the above-mentioned intelligent test and sorting platform for button droppers includes the following steps:

[0065] (1) Arrange the button droppers in a row through the feeding mechanism 1 and move the row of button droppers to the picking station 4;

[0066] (2) Pick up the button droppers at the picking station 4 through the first picking and placing mechanism 5 and place them on the sorting mechanism 2 to detect the flow rate of each button dropper;

[0067] (3) Pick up the button droppers after the detection through the second picking and placing mechanism 6 and move them above the sorting mechanism 3, and place the button droppers separately according to the flow rate through the sorting mechanism 3.

[0068] During specific operation, the button droppers to be sorted are placed in the vibrating loading tray 11. The controller controls the start of the vibrating loading tray 11 and the swinging motor 132. As the swinging plate 12 moves, the button droppers are pushed to each placement groove 121 of the swinging plate 12 through the output end of the vibrating loading tray 11 to complete the material placement. The swinging plate 12 stops moving after moving to the material taking station 4. The controller controls the first horizontal motor 58 to act so that the first picking and placing mechanism 5 moves to the material taking station 4. The controller controls the first vertical motor 55 to act so that the first pneumatic gripper 52 moves downward and starts the first pneumatic gripper 52 to pick up the material. When the first pneumatic gripper 52 starts, the air extraction pump starts to cooperate with the material picking. After the material picking is completed, the first vertical motor 55 acts to move the first pneumatic gripper 52 upward. The first horizontal motor 58 acts to move the first picking and placing mechanism 5 above the sorting mechanism 2 and stop. The swinging motor 132 acts to move the swinging plate 12 to the initial position to prepare for cooperating with the vibrating loading tray 11 to place materials again. The controller controls the first vertical motor 55 to act so that the first pneumatic gripper 52 and the button dropper to be inspected move downward, and the lower ends of the button droppers are inserted into the tops of the test water pipes 23 one by one. At this time, the controller controls the water delivery pump 28 to start to detect the flow rate of each button dropper. The test time is preset in the system of the controller. The flow meter 27 transmits the flow rate data of each button dropper to the controller. The controller analyzes and matches each button dropper with the corresponding distribution pipe 31 according to the flow rate. After the detection is completed, the first pneumatic gripper 52 releases the button dropper. After the first vertical motor 55 acts to move the first pneumatic gripper 52 upward, the first horizontal motor 58 acts to move the first picking and placing mechanism 5 to the material taking station 4 again to prepare for the next material picking. The controller controls the second horizontal motor 68 to act so that the second picking and placing mechanism 6 moves above the sorting mechanism 2 and stops. The second vertical motor 65 acts to move the second pneumatic gripper 62 downward and starts the second pneumatic gripper 62 to pick up the inspected button dropper. When the second pneumatic gripper 62 starts, the air extraction pump starts to cooperate with the material picking. The second vertical motor 65 acts to move the second pneumatic gripper 62 and the inspected button dropper upward. The second horizontal motor 68 acts to move the second picking and placing mechanism 6 above the distribution mechanism 3. According to the flow rate detection result, the controller controls the second horizontal motor 68 and the second vertical motor 65 to move the second pneumatic gripper 62 and the button dropper, and places the button dropper into the corresponding distribution pipe 31, and it falls into the corresponding storage tank 32 through each blanking pipe 33 for storage.
