Description

Technical Field

[0001] This application relates to the technical field of sealing detection jigs, and particularly to an automatic detection device for the sealing performance of a water storage box. Background Art

[0002] Intelligent household appliances, such as floor sweeping robots and mopping machines, have gradually become popular nowadays due to their simple operation functions and convenience, and have become common household appliances in modern families. In order to achieve the mopping function, a water storage box is usually provided in a floor sweeping robot and a mopping machine. Since the structure of the water storage box is relatively complex, the water storage box is usually formed by ultrasonic welding of two or more plastic parts.

[0003] Airtightness detection is a necessary step after the welding of the water storage tank and an important guarantee for improving the reliability of the water storage tank. The method is to install the water storage box on an airtightness detector, block the water inlet and outlet on the water storage box with rubber gaskets, and then introduce air through the ventilation hole. If the pressure relief pressure exceeds the set range within the set time, the device will alarm, and thus it can be determined whether the part is qualified.

[0004] Existing airtightness detection jigs usually consist of a positioning device and a clamping device. The detection jig can hold the water storage box to a certain extent, but its matching degree with the water storage box is still not high enough, and the clamping stability and the protection effect on the shape stability of the water storage box are still insufficient. Since the shape and structure of the water storage box product are delicate and complex, the airtightness detection jig needs to be designed according to its structure to achieve more accurate positioning and more stable clamping.

[0015] Optionally, the plugging component includes two groups of plugging cylinders, a plug, and a rubber sheet. The plugging cylinders are installed on the workbench, and the piston rods of the two plugging cylinders are both arranged towards the jig. The plug is installed on the piston rod of the plugging cylinder. The plug is cylindrical. The rubber sheet is pasted on the end wall of the plug, and the diameter of the rubber sheet is larger than the diameter of the plug. Two semi-circular grooves are penetrated on the side wall of the jig close to the plugging cylinder. The axis of the semi-circular groove coincides with the axis of the plug, and the plug is slidably arranged in the semi-circular groove.

Detailed implementation manners

[0032] The following further elaborates on the present application in conjunction with the attached Figures 1-5 for a more detailed description.

[0033] The embodiment of the present application discloses an automatic detection equipment for the sealing performance of a water storage box.

[0034] Refer to Figure 1 , the water storage box 7 of the present application is as Figure 1As shown in the figure, an inlet joint 71 and an outlet joint 72 are provided on the side wall of the water storage box 7. Both the inlet joint 71 and the outlet joint 72 are cylinders. An inlet port 73 and an outlet port 74 are respectively penetrated through the centers of the inlet joint 71 and the outlet joint 72, and the inlet port 73 and the outlet port 74 are communicated with the inside of the water storage box 7. The diameters of the inlet joint 71 and the outlet joint 72 are greater than the thickness of the water storage box 7, and the peripheral walls of the inlet joint 71 and the outlet joint 72 protrude from the top wall and the bottom wall of the water storage box 7; the end walls of the inlet joint 71 and the outlet joint 72 are concave, and are recessed inward from the edge towards the center. A vent hole 75 is also provided on the top wall of the water storage box 7, and a semi-permeable membrane is pasted on one side of the vent hole, which only allows air to enter the water storage box 7 unidirectionally through the vent hole 75 from the outside of the water storage box 7, for adjusting the air pressure inside the water storage box 7. The vent hole 75 is located at the corner of the top wall of the water storage box 7.

[0035] Referring to Figure 2 , the automatic detection equipment for the sealing performance of the water storage box includes a working frame 13, and the working frame 13 is placed on the ground. A workbench 1 is installed on the working frame 13 by bolts, and a fixture 2 is installed on the top wall of the workbench 1 by bolts. A placement groove 21 for placing the water storage box is provided on the top wall of the fixture 2. A leak plugging component 3 is provided on the workbench 1, and the leak plugging component 3 is located on one side of the fixture 2 in the width direction; a pressing component 4 is provided on the workbench 1, and the pressing component 4 is located on one side of the fixture 2 in the length direction. The pressing component 4 and the leak plugging component 3 are arranged perpendicular to each other in the horizontal direction. A gantry 12 is installed on the workbench 1 by bolts, and a detection component 5 is provided on the gantry 12. The detection component 5 is suspended above the fixture 2 near the vent hole.

[0036] The operator places the water storage box with the vent hole facing up in the placement groove 21. The leak plugging component 3 is matched with the positions of the inlet port and the outlet port, the pressing component 4 is matched with the side wall of the water storage box, and the detection component 5 is matched with the vent hole. The operator starts the equipment, and the leak plugging component 3 and the pressing component 4 are started simultaneously. The leak plugging component 3 seals the inlet port and the outlet port and at the same time presses the water storage box against the first side wall of the placement groove 21, and the pressing component 4 presses the water storage box against the second side wall perpendicular to the first side wall. The positioning, clamping and sealing of the water storage box are completed, and it is difficult for the water storage box to move by itself. Subsequently, the detection component 5 is started to check the air tightness through the vent hole. After the detection is completed, the detection component 5 is reset first, and then the leak plugging component 3 and the pressing component 4 are reset.

[0037] The detection component 5 includes a detection cylinder 51. The housing of the detection cylinder 51 is installed on the bottom wall of the gantry 12 by bolts, and the piston rod of the detection cylinder 51 hangs directly above the vent hole. A seal 52 is installed on the piston rod of the detection cylinder 51 by bolts, and a trachea is connected to the seal 52. The end of the trachea far from the seal 52 is connected to a gas source.

[0038] The detection cylinder 51 drives the seal 52 to descend until the seal 52 seals the air vent hole. Subsequently, the gas source injects the detection gas into the water storage box through the air pipe and the seal 52 and monitors the air pressure change. The equipment and principle of the airtightness detection are both prior arts.

[0039] Referring to Figure 3 , the leak plugging assembly 3 includes two leak plugging cylinders 31. The outer shell of the leak plugging cylinder 31 is installed on the top wall of the workbench 1 through bolts, and the piston rods of the two leak plugging cylinders 31 are both arranged towards the first side wall. A plug 32 is installed on the piston rod of the leak plugging cylinder 31 through bolts. The plug 32 is cylindrical. The diameter of the plug 32 is smaller than the diameters of the water inlet joint and the water outlet joint but larger than the diameters of the water inlet and the water outlet. A rubber sheet 33 is pasted on the end wall of the plug 32 close to the first side wall. The diameter of the rubber sheet 33 is larger than the diameter of the plug 32 and smaller than the diameters of the water inlet joint and the water outlet joint.

[0040] The pressing assembly 4 includes a pressing cylinder 41. The outer shell of the pressing cylinder 41 is installed on the top wall of the workbench 1 through bolts, and the piston rod of the pressing cylinder 41 is arranged towards the second side wall. A pressing block 42 is installed on the piston rod of the pressing cylinder 41 through bolts. A rubber pad 43 is pasted on the end wall of the pressing block 42 close to the second side wall.

[0041] Referring to Figure 3 , a base 22 is arranged on the bottom wall of the placement groove 21. The base 22 is integrally formed with the fixture 2. The top wall of the base 22 is horizontally arranged and lower than the top wall of the fixture 2. Two support blocks 23 are arranged on the top wall of the base 22. Both of the two support blocks 23 are located on one side of the base 22 close to the first side wall and are respectively located at both ends of the length direction of the base 22. The support blocks 23 are integrally formed with the base 22. The top walls of the support blocks 23 are horizontally arranged and lower than the top wall of the fixture 2. The shapes of the base 22 and the support blocks 23 match the shape of the bottom wall of the water storage box. A relief groove 24 is formed on the top wall of the base 22. The relief groove 24 is located on one side of the base 22 close to the third side wall. The relief groove 24 is adapted to the water inlet joint and the water outlet joint.

[0042] Two semi-circular grooves 25 are formed through the third side wall of the fixture 2 close to the leak plugging cylinder 31. The axis of the semi-circular groove 25 coincides with the axis of the plug 32. The plug 32 is slidably arranged in the semi-circular groove 25. A square groove 26 is formed through the fourth side wall of the fixture 2 close to the pressing cylinder 41. The pressing block 42 is slidably arranged in the square groove 26.

[0043] The operator controls the water storage box to be placed into the jig 2 along the first side wall and the second side wall until the bottom wall of the water storage box is in contact with the top walls of the support block 23 and the base 22, and the parts of the water inlet joint and the water outlet joint protruding from the water storage box body are located in the relief groove 24. The plugging cylinder 31 drives the plug 32 to move along the inner wall of the semi-circular groove 25 towards the water storage box. The rubber sheet 33 abuts against the end walls of the water inlet joint and the water outlet joint, sealing the water inlet and the water outlet while pressing the water storage box tightly against the first side wall. The pressing cylinder 41 drives the pressing block 42 to move along the inner wall of the square groove 26 towards the water storage box. The rubber pad 43 abuts against the side wall of the water storage box, pressing the water storage box tightly against the second side wall. The semi-circular groove 25 and the square groove 26 can improve the positioning accuracy. When testing, the plug 32 and the pressing block 42 make it difficult for the water storage box to move, and the base 22 and the support block 23 jointly support the water storage box against the pressure of the seal 52. The support block 23 and the base 22 can improve the positioning accuracy and the stability during the detection process.

[0044] Refer to Figure 4 , a cavity 221 is provided inside the base 22. Four vertical round holes 222 are opened on the top wall of the base 22. A horizontal through groove 223 is opened on the side wall of the base 22 close to the pressing block 42. The round holes 222 and the through groove 223 communicate with the cavity 221.

[0045] Refer to Figure 4 and Figure 5 , a lifting rod 61 is slidably arranged in the round hole 222. The bottom end of the lifting rod 61 is connected to the base 22 by a spring. An annular notch 611 is opened in the middle of the lifting rod 61. The inner diameter of the annular notch 611 is smaller than the diameter of the lifting rod 61. An insertion piece 62 is arranged at the annular notch 611. A semi-circular notch is opened on the side wall of the insertion piece 62 close to the lifting rod 61, and the semi-circular notch is adapted to the outer peripheral wall of the lifting rod 61. An installation frame 64 is arranged in the cavity 221, and all four insertion pieces 62 are clamped and fixed to the installation frame 64. A horizontal track 63 is arranged in the cavity 221. The installation frame 64 is provided with a groove corresponding to the track 63, and the installation frame 64 is slidably matched with the track 63. A movable plate 65 is installed on the installation frame 64, and the movable plate 65 is located at the part of the cavity 221 close to the through groove 223. A spring is installed on the left side wall of the movable plate 65 away from the pressing block 42, and the other end of the spring is connected to the inner wall on the left side of the cavity 221.

[0046] A movable rod 67 is inserted into the through groove 223. One end of the movable rod 67 passes through the rubber pad 43 and is connected to the abutting block 42 by bolts. The other end is provided with two paddles 68, and the paddles 68 are made of elastic metal material. The paddles 68 are arranged towards the movable plate 65. A convex block 69 is installed on the bottom wall of the end of the paddle 68 far from the movable rod 67, and the convex block 69 is an inverted equilateral triangle. A convex strip 66 is installed on the top wall of the movable plate 65, and the cross section of the convex strip 66 is rectangular. The height of the convex block 69 is adapted to the height of the convex strip 66.

[0047] When the abutting block 42 moves away from the base 22, the top end of the lifting rod 61 protrudes from the top wall of the base 22 through the round hole 222. The inserting piece 62 is located below the annular notch 611, and the convex block 69 is away from the convex strip 66. The operator places the water storage box into the jig 2. The bottom wall of the water storage box contacts the top end of the lifting rod 61. As the water storage box descends, the water storage box drives the four lifting rods 61 to move downward simultaneously, and the springs at the bottom ends of the lifting rods 61 are compressed; the inserting piece 62 slides along the outer peripheral wall of the lifting rod 61. When the bottom wall of the water storage box contacts the top wall of the base 22, the lifting rod 61 completely retracts into the round hole 222. The movable plate 65, the mounting bracket 64 and the four inserting pieces 62 move leftward under the action of the spring, and the inserting piece 62 is inserted into the annular notch 611 to lock the lifting rod 61. The above setting can play a certain anti-mistake effect. If the water storage box is placed obliquely, the lifting rod 61 cannot be locked. After the operator releases the hand, the lifting rod 61 will jack up the water storage box.

[0048] When the abutting block 42 moves closer to the base 22, the movable rod 67 drives the paddle 68 to approach the movable plate 65 from the right side until the convex block 69 contacts the convex strip 66. The convex block 69 exerts a leftward pressure on the movable plate 65 through the convex strip 66, making it difficult for the movable plate 65 to move. The paddle 68 deforms, and the convex block 69 crosses over the convex strip 66 to reach the left side of the convex strip 66, and the paddle 68 returns to the straight state. After the detection is completed, the abutting block 42 moves in the direction away from the base 22 to release the water storage box. The movable rod 67 drives the paddle 68 and the convex block 69 to approach the convex strip 66 from the left side. When the convex block 69 contacts the convex strip 66, it exerts a rightward pressure on the convex strip 66. The convex strip 66 drives the movable plate 65, the mounting bracket 64 and the four inserting pieces 62 to move rightward simultaneously. After the inserting piece 62 disengages from the lifting rod 61, the lifting rod 61 moves upward under the action of the bottom spring to jack up the water storage box, facilitating the operator to take away the water storage box.

[0049] As the distance that the inserting piece 62 moves rightward increases, the pulling force of the spring on the movable plate 65 to the left increases, and the paddle 68 undergoes elastic deformation to make the convex block 69 cross over the convex strip 66 to reach the right side of the convex strip 66. After the convex block 69 disengages from the convex strip 66, the spring pulls the movable plate 65 back, and the inserting piece 62 abuts against the peripheral wall of the lifting rod 61 below the annular notch 611.

[0050] The implementation principle of the automatic detection device for the sealing performance of the water storage box in the embodiment of the present application is as follows: The operator places the water storage box in the fixture 2. The water storage box forces the four lifting rods 61 to move downward, and the insertion piece 62 is inserted into the annular notch 611 to lock the lifting rod 61. The support block 23 and the base 22 jointly support the fixture 2, and the plug 32 and the pressing block 42 jointly fix the water storage box. The pressing block 42 drives the movable rod 67 to move leftward. The insertion piece 62 and the movable plate 65 remain stationary, and the dial 68 undergoes elastic deformation, and the convex block 69 crosses the convex strip 66 to reach the left side of the convex strip 66. When the detection is completed, the pressing block 42 drives the movable rod 67 to move rightward. The convex block 69 exerts a rightward pressure on the convex strip 66, driving the movable plate 65, the mounting bracket 64, and the four insertion pieces 62 to move rightward simultaneously. After the insertion piece 62 disengages from the lifting rod 61, the lifting rod 61 moves upward under the action of the bottom spring to lift the water storage box, facilitating the operator to take away the water storage box. As the distance that the insertion piece 62 moves rightward increases, the pulling force of the spring on the movable plate 65 to the left increases, and the dial 68 undergoes elastic deformation to make the convex block 69 cross the convex strip 66 to reach the right side of the convex strip 66. After the convex block 69 disengages from the convex strip 66, the spring pulls the movable plate 65 back, and the insertion piece 62 abuts against the peripheral wall of the lifting rod 61 below the annular notch 611.
