DETAILED DESCRIPTION

[0028] Example

[0029] like Figures 1 to 10As shown, the automatic testing system for a double-outlet washing pump provided in this embodiment includes a machine 1, a fixing seat 2, a black and white water outlet pressing device 3, a mobile grasping device 5, an end cover air-tightness detection device 6, a pump cover air-tightness detection device 7, a forward detection device 8, a reverse detection device 9, a water blowing device 10 and a controller 13. Two groups of the fixing seat 2, the end cover air-tightness detection device 6, the pump cover air-tightness detection device 7, the forward detection device 8, the reverse detection device 9 and the water blowing device 10 are sequentially installed on the machine 1. The two groups of the fixing seat 2, the end cover air-tightness detection device 6, the pump cover air-tightness detection device 7, the forward detection device 8, the reverse detection device 9 and the water blowing device 10 can effectively increase the test volume of the test line, and the worker can place two washing machines at the same time with both hands. The pump can effectively improve the detection efficiency. The machine platform 1 is evenly spaced with bases 4 corresponding to the end cover airtight detection device 6, the pump cover airtight detection device 7, the forward detection device 8, the reverse detection device 9 and the water blowing device 10. The black and white water outlet pressing device 3 is installed on the machine platform 1 on one side of the fixed seat 2. The fixed seat 2 includes a support plate 21, a limit seat 22 and a reciprocating motion device 23. The surfaces of the limit seat 22 and the base 4 are processed with limit grooves that are adapted to the contour of the washing pump. The limit seat 22 can be slidably installed on the support plate 21. The reciprocating motion device 23 is connected to the limit seat 22 and drives the limit seat 22 to move toward the end cover airtight detection device 6. The mobile grasping device 5 is installed on the end cover airtight detection device 6, the pump cover airtight detection device 7, the forward detection device 8, the reverse detection device 9 and the water blowing device 10. On one side of the airtight detection device 7, the forward detection device 8, the reverse detection device 9 and the water blowing device 10, the mobile grasping device 5 includes a fixed plate 51, a sliding seat 52, a slide rail 53, a displacement cylinder 54 and a manipulator 55. The sliding seat 52 is installed on the fixed plate 51, and the slide rail 53 is horizontally slidably installed on the sliding seat 52. The displacement cylinder 54 is installed on the fixed plate 51. The piston rod of the displacement cylinder 54 is connected to the slide rail 53 to drive the slide rail 53 to reciprocate on the moving sliding seat. Six sets of the manipulators 55 are installed on the slide rail 53 at equal intervals, and each set of the manipulators 55 is located at the base 4 of the end cover airtight detection device 6, the pump cover airtight detection device 7, the forward detection device 8, the reverse detection device 9 and the water blowing device 10. One by one, six sets of manipulators 55 move synchronously. The controller 13 is connected with the fixed seat 2, the black and white water outlet pressing device 3, the mobile grasping device 5, the end cover air tightness detection device 6, the pump cover air tightness detection device 7, the forward detection device 8, the reverse detection device 9 and the water blowing device 10, and is used to control the actions of the fixed seat 2, the black and white water outlet pressing device 3, the mobile grasping device 5, the end cover air tightness detection device 6, the pump cover air tightness detection device 7, the forward detection device 8, the reverse detection device 9 and the water blowing device 10, and upload the test data to the host computer. The controller 13 is a PLC controller 13, and the host computer is the control touch screen and the background computer on the machine 1. The control touch screen is a human-computer interactive touch screen, that is, the test results are displayed in real time.You can also adjust the set parameters as needed.

[0030] In order to ensure the operation of the mobile grabbing device 5, Figure 1 to Figure 3 As shown, after the reciprocating motion device 23 drives the limit seat 22 to move toward the end cover airtightness detection device 6 to the extreme position, the distance between the limit seat 22 and the end cover airtightness detection device 6 is equal to the distance between adjacent manipulators 55, which can facilitate the manipulator 55 to grasp the workpiece automatically for subsequent automatic testing.

[0031] To facilitate the testing of the washing pump, Figure 4 , Figure 5 As shown, the black and white water outlet pressing device 3 includes a mounting plate 31, a pressing cylinder 32, a water inlet valve 33, a water return valve 34 and a water storage tank 35. The mounting plate 31 is vertically arranged on the machine platform 1. There are three groups of pressing cylinders 32, and the three groups of pressing cylinders correspond to one water inlet and two water outlets of the washing pump respectively. The water inlet valve 33 is connected to the pressing cylinder 32 corresponding to the water inlet, and the water return valve 34 is installed on the pressing cylinder 32 corresponding to the water outlet. When in use, the pressing cylinder 32 respectively presses the water inlet valve 33 of the washing pump. The return valve 34 is press-fitted onto the washing pump body to complete the assembly of the washing pump; a three-way valve 37 connected to the water storage tank 35 is installed on the piston rod of the pressing cylinder 32 corresponding to the water inlet valve 33 and the return valve 34, and the three-way valve 37 corresponding to the return valve 34 is connected to the water storage tank 35 through a circulation pipe, and three groups of electromagnetic valves 36 are installed on the circulation pipe. The electromagnetic valve 36 located in the middle is connected to the water storage tank 35. By opening different three groups of electromagnetic valves 36, the directions of the black and white water outlets can be adjusted, and the two outlet states of the washing pump can be detected respectively.

[0032] like Figure 8 As shown, the end cover airtight detection device 6 and the pump cover airtight detection device 7 have the same structure, both of which include an airtight detection control cylinder 61, an airtight connector 62 and an airtight detection device 63. The airtight connector 62 is installed on the piston rod of the airtight detection control cylinder 61. The airtight detection control cylinder 61 drives the airtight connector 62 to connect with the end cover or pump cover of the washing pump. The airtight connector 62 is connected to the airtight detection device 63. The airtight connector 62 is a common connector for detecting airtightness. When in use, the airtight detection control cylinder 61 drives the airtight connector 62 to connect with the washing pump, and then the airtight detection device 63 delivers compressed gas of a certain pressure to the washing pump and maintains the pressure, thereby judging the airtightness of the washing pump and the pump cover. Due to the different positions of the end cover and the pump cover, two workstations are set for separate detection.

[0033] like Fig. 9As shown, the forward detection device 8 and the reverse detection device 9 have the same structure, both of which include a rotation detection control cylinder 81, a water inlet connector 82, a water solenoid valve 83 and a power supply harness 84. The water inlet connector 82 is installed on the piston rod of the rotation detection control cylinder 81, and the water inlet connector 82 is connected to the water tank through a pipeline. The water solenoid valve 83 is connected to the pipeline, and the power supply harness 84 is adjacent to the washing pump. The positive and negative poles of the power supply harness 84 of the forward detection device 8 and the reverse detection device 9 are in opposite directions. When in use, the rotation detection control cylinder 81 drives the water solenoid valve 83 to connect with the washing pump, and the power supply harness 84 is connected to the wiring terminal of the washing pump. Subsequently, the power supply harness 84 is energized, and the water solenoid valve 83 is opened, and the washing pump works to pump water out from the two outlets respectively, thereby detecting the efficiency. Since the forward detection and reverse detection of the washing pump are only in opposite directions of the power supply, two workstations are set for separate detection.

[0034] In order to ensure the factory cleaning of the washing pump, Fig.10 As shown, the water blowing device 10 includes a water blowing control cylinder 1001 and an air blowing valve 1002. The air blowing valve 1002 is connected to the piston rod of the water blowing control cylinder 1001. The air blowing valve 1002 is connected to the compressed air storage tank through a pressure-resistant pipe. A valve is connected to the pressure-resistant pipe. When in use, the water blowing control cylinder 1001 drives the air blowing valve 1002 to connect to the washing pump, and then the valve is opened to blow compressed gas into the washing pump to blow out water during front side detection.

[0035] In order to automatically sort out qualified and unqualified washing pumps, such as Figure 1 As shown, a trough 11 for screening qualified products is installed on the machine 1 at the rear side of the water blowing device 10. The trough 11 is rotatably connected to the machine 1. A rotating cylinder 12 connected to the trough 11 is installed on the machine 1. When in use, the controller 13 controls the position of the rotating cylinder 12 according to the detection result, and uses the rotating cylinder 12 to drive the discharging direction of the trough 11, thereby eliminating the process of re-sorting.

[0036] To ensure the clamping of the washing pump, Figure 6 , Figure 7As shown, the manipulator 55 includes a telescopic cylinder 551, a sliding arm 552 and a clamping cylinder 553. The telescopic cylinder 551 is suspended on the slide rail 53, and the sliding arm 552 is slidably installed on the side wall of the telescopic cylinder 551. The piston rod of the telescopic cylinder 551 is connected to the sliding arm 552, and the clamping cylinder 553 is connected to the bottom of the sliding arm 552. The telescopic cylinder 551 and the clamping cylinder 553 are mutually controlled, which can facilitate the grabbing and putting down of the washing pump. When grabbing, the telescopic cylinder 551 extends, driving the sliding arm 552 to move downward, and then the clamping claw cylinder 553 clamps the washing pump, and then the telescopic cylinder 551 is retracted, driving the sliding arm 552 to rise, and the washing pump is clamped from the base 4 or the limit seat 22; when placing down, the telescopic cylinder 551 extends, driving the sliding arm 552 to move downward, and then the clamping claw cylinder 553 releases the washing pump, and then the telescopic cylinder 551 is retracted, driving the sliding arm 552 to rise, and the washing pump is placed on the base 4 or the material trough 11.

[0037] The method of using the present invention is:

[0038] Manually install the washing pump to be tested in the limit seat 22 on the fixed seat 2 on one side of the machine 1 near the fixed seat 2. At this time, the black and white water outlet pressing device 3 installs the black and white water outlets of the washing pump. Then the three-way valve 37 is opened, and the water in the water storage tank 35 flows into the washing pump through the water inlet valve 33, and then flows back to the water storage tank 35 from the return valve 34. During the return process, the three groups of electromagnetic valves 36 respectively detect the two outlet states of the washing pump. After the detection is completed, the reciprocating motion device 23 drives the limit seat 22 to move toward the end cover airtightness detection device. After moving into place, the displacement cylinder 54 on the mobile grasping device 5 extends out, so that the manipulator 55 near the fixed seat 2 is located above the limit seat 22, and then the manipulator 55 is controlled to clamp the washing pump, and then the displacement cylinder 54 is retracted to move the manipulator 55 back one station, and then the manipulator 55 puts the washing pump into the station. The washing pump is then moved to the base 4 at the same time, and the reciprocating motion device 23 is retracted. The worker then installs the next washing pump on the limit seat 22, and then the end cover airtightness detection device 6 detects the end cover seal of the washing pump. After the detection is completed, the mobile grasping device 5 and the reciprocating motion device 23 work again to move the washing pump to the next station, and repeat the above steps to make the washing pump pass through the subsequent pump cover airtightness detection device 7, the forward detection device 8, the reverse detection device 9 and the water blowing device 10 in sequence until all tests of the washing pump are completed. The washing pump is moved toward the material trough 11 by the manipulator 55 on the rear side. During the process again, the controller 13 compares the test data with the set data. If all the test data are qualified, the material trough 11 will transfer the qualified products to the qualified product box. If any test data is unqualified, the rotating cylinder 12 drives the material trough 11 to the unqualified product box.

[0039] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any modification and replacement based on the technical solution and inventive concept provided by the present invention shall be included in the protection scope of the present invention. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the present invention omits the description of known components and processing technologies and processes to avoid unnecessary limitation of the present invention.
