Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, specifically relating to a floor scrubber nozzle testing device. Background Technology

[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors while simultaneously vacuuming up and removing wastewater from the site. It has advantages such as being environmentally friendly, energy-saving, and highly efficient. A floor scrubber mainly consists of four parts: an electric roller brush, a wastewater tank, a clean water tank, and a motor. During operation, clean water is sprayed from the clean water tank through a water pipe and then through the nozzle. The roller brush starts to rotate rapidly under the action of the motor, separating dirt from the floor. At the same time, the suction force creates a vacuum in the wastewater tank, thereby sucking the wastewater on the roller brush into the wastewater tank, keeping the roller brush clean. Through the cycle of water spraying, roller brush cleaning, and wastewater recycling, the floor is cleaned.

[0003] To improve cleaning effectiveness, existing floor scrubbers add chemical components with cleaning, deodorizing, and conditioning functions to the clean water tank. These components, when sprayed, form ultra-micro energy bubbles on the floor. To improve the evenness of distribution, the nozzles of these floor scrubbers are mostly designed like... Figure 1 As shown, it has an inlet at the bottom and a strip-shaped front outlet at the front to achieve a fan-shaped spray surface. When leaving the factory, this type of nozzle needs to be tested for the actual effect of the fan-shaped spray surface. The traditional testing method is manual hand-held spraying and manual visual inspection, which is complicated to operate. The spray angle and spray pressure are greatly affected by the operator, and the judgment criteria for the fan-shaped spray surface also vary from person to person, resulting in poor testing accuracy. It is difficult to guarantee the consistency of product quality leaving the factory, resulting in a high customer complaint rate and return rate. Utility Model Content

[0025] like Figures 2 to 10 As shown, the floor scrubber nozzle testing device provided by this utility model includes: a frame 10, a support plate 20, a product seat 30, a clamping assembly 40, a water supply pipe 50, a water receiving tank, a vision camera 70, and a control unit. The frame 10 is constructed from aluminum alloy profiles and has rollers at its bottom, allowing it to be a movable frame. The support plate 20 is located in the middle of the frame 10, and its plane is parallel to the horizontal plane. The product seat 30 is mounted on the support plate 20, and its upper surface... The shape matches the bottom contour of the nozzle 1; the clamping assembly 40 includes a clamping plate 41 rotatable above the support base 20 and a cylinder 42 that drives the clamping plate 41 to move up and down. Specifically, the cylinder 42 is a single-rod cylinder and is mounted on the support plate 20. One end of the clamping plate 41 is connected to the end of the cylinder rod of the cylinder 42. By rotating the cylinder rod of the cylinder 42, the clamping plate 41 can be rotated horizontally. The other end is suspended and its lower end is connected to a retractable clamping column. There are two sets of clamping components 40, located on the left and right sides of the product base 30 respectively. The clamping plates 41 of these two sets of clamping components 40 are respectively set at the front and rear ends of the nozzle 1. The water supply pipe 50 is located behind the product base 30 with its opening facing upward. When the clamping plate 41 presses the nozzle 1 onto the product base 30, the opening of the water supply pipe 50 is connected to the bottom inlet 2 of the nozzle 1. The water receiving tank includes a first groove 61 located behind the product base 30 and a second groove 62 located below the product base 30. The first groove 61 and the second groove 62 are connected to the bottom of the corresponding opening of the support plate 20. The first groove 61 and the second groove 62 extend downward and gradually narrow inward. The first groove 61 is used to receive water sprayed from the front outlet 3 of the nozzle 1, and the second groove 62 is used to receive water leaked from the nozzle 1 during testing. The vision camera 70 is set above the product base 30 and aligned with the fan-shaped spray surface formed above the first groove 61 by the front outlet 3. The control unit is connected to the vision camera 70 and stores images of the normal fan-shaped spray surface.

[0026] The advantage of this setup is that when testing the effect of the spray pattern of the nozzle, simply place the nozzle on the support base, rotate the clamping plate, and use the cylinder to press the clamping plate against the nozzle. Water can then be supplied to the nozzle through the water supply pipe, causing the nozzle's front outlet to spray a fan-shaped spray pattern. By capturing images with a vision camera and comparing them with pre-stored normal images in the control unit, it can be determined whether the nozzle's quality meets the requirements. The operation is simple, the spray angle and pressure are fixed, the judgment criteria are clear, and the accuracy of the test results is higher. This ensures the consistency of product quality and reduces customer complaints and return rates.

[0027] It should be noted that if there is a leak in the nozzle itself, the shape of the fan-shaped spray surface ejected from the nozzle's front outlet will change under the premise that the water pressure and water supply remain unchanged. This test can also indirectly test the nozzle's sealing characteristics.

[0028] To make the images captured by the vision camera 70 clearer and easier to compare, in this embodiment, a light source plate 31 is provided below the product base 30. The light source plate 31 emits colored light to illuminate the fan-shaped spray surface ejected from the front outlet 3. Furthermore, support seats 32 are provided at both ends of the light source plate 31. The light source plate 31 and the support seats 32 are rotatably connected to adjust the irradiation angle of the colored light.

[0029] To facilitate the setup and angle adjustment of the vision camera 70, the floor scrubber nozzle detection device also includes a door-frame-shaped bracket 71 that frames the left and right sides of the product base 30. The vision camera 70 is suspended on the bracket 71 via a position adjustment component 72. Specifically, the position adjustment component 72 includes a first clamping block 721, a vertical rod 722, a second clamping block 723, a horizontal rod 724, and a third clamping block 725. The first clamping block 721 is fixed to the middle of the horizontal beam of the bracket 71, and the upper end of the vertical rod 722... The first clamping block 721 is movably clamped, and the second clamping block 723 is located below the first clamping block 721. One end of the second clamping block 723 is movably and rotatably clamped to the vertical bar 722, and the other end is movably and rotatably clamped to the horizontal bar 724. The third clamping block 725 is located on one side of the second clamping block 723 and is movably and rotatably clamped to the horizontal bar 724. The vision camera 70 is fixed to the front end of the third clamping block 725. To achieve traceability, the crossbeam of the bracket 71 is further equipped with a barcode scanner 73 for detecting the barcode or QR code on the nozzle 1. The barcode scanner 73 is connected to the control unit. Before detecting the nozzle 1, the barcode or QR code on the nozzle 1 is aligned with the barcode scanner 73. After successful scanning, the green indicator light on the barcode scanner 73 lights up. After the green light is on, the nozzle 1 is placed on the product seat 30 for subsequent detection procedures.

[0030] To prevent water from splashing out of the front outlet 3, the floor scrubber nozzle testing device also includes a vertical enclosure 611 surrounding the front and left and right sides of the first tank 61. The upper edge of the enclosure 611 is folded inward horizontally to form an inner edge 612. To achieve the recycling of the test water, a water tank 63 is further provided below the first tank 61 and the second tank 62. The side wall of the water tank 63 is provided with a first connector 64. The first connector 64 is connected to the water supply pipe 50 through a water pump 65 and a pipe (with a solenoid valve).

[0031] To remove residual water inside the nozzle 1 after testing, a second connector 51 is connected to the water supply pipe 50. The second connector 51 is connected to the air supply pipe (not shown in the figure). The air supply pipe is equipped with a solenoid valve (not shown in the figure). After the test is completed, the air supply pipe is turned on, the water pump 65 and the pipeline are disconnected, and high-pressure gas enters the bottom inlet 2 of the nozzle 1 through the water supply pipe 50 and is ejected from the front outlet 3, thereby blowing out the residual water inside the nozzle 1.

[0032] The control unit includes a computer host 81, a monitor 82, and a control box 83. The front end of the rack 10 is provided with a tray 11 for supporting the keyboard and mouse, a start button 12 for controlling the action of the cylinder 42, and a safety light curtain 13 to prevent personnel limbs from entering the detection area. The computer host 81 is located on the lower right side of the rack 10, the monitor 82 is located on the top of the rack 10 and is higher than the bracket 71, and the control box 83 is located on the upper right side of the rack 10, and is provided with a display screen, indicator lights and control buttons.
