[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0036] In the description of this invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0037] like Figures 1 to 9As shown, the brake pad cleaning device of the present invention includes: a frame 100, on which a plurality of ultrasonic transducers 200 are installed, and a plurality of cleaning chambers 101 are opened inside the frame 100, wherein the brake pads are cleaned in the cleaning chambers 101.

[0038] The ultrasonic transducer 200 is matched with the cleaning chamber 101, so that the ultrasonic transducer 200 can perform the cleaning work on the corresponding cleaning chamber 101. A heating device can be installed in the cleaning chamber 101 as needed to heat the ultrasonic cleaning fluid, so as to improve the cleaning effect.

[0039] In one embodiment, the frame 100 has flow lines on both sides, one being a feeding flow line 300 and the other a discharging flow line. The processed brake pads are transported to any cleaning chamber 101 via the feeding flow line 300. Then, the worker puts the brake pads into the cleaning chamber 101 for cleaning. Moreover, the worker can place the cleaned brake pads inside the cleaning chamber 101 onto the discharging flow line, so that the brake pads flow to the next process along the discharging flow line.

[0040] By setting up the feed flow line 300 and the discharge flow line, manual transportation of brake pads can be assisted, reducing the labor intensity of manual labor.

[0041] A fixed connecting plate 102 is fixedly installed inside the frame 100. A guide rod 103 is fixedly installed on the fixed connecting plate 102. A lifting plate 104 is slidably arranged on the guide rod 103. The lifting plate 104 can move up and down along the guide rod 103. The brake pad is placed on the lifting plate 104. When the lifting plate 104 moves up and down, the brake pad moves up and down accordingly, so that the ultrasonic cleaning fluid can fully contact the brake pad, resulting in a good cleaning effect.

[0042] It should be noted that four studs 105 are fixedly installed on the lifting plate 104. The four studs 105 contact the brake pads and limit their movement. In actual use, the side of the brake pads can contact the studs 105. Nuts can be screwed into the studs 105 as needed to limit the upper and lower positions of the brake pads.

[0043] A guide post 106 is fixedly installed on the fixed connecting plate 102. An arc-shaped guide groove 1061 is provided on the guide post 106. A connector 107 is slidably installed on the guide post 106. The connector 107 is connected to the lifting plate 104. A connecting protrusion 108 is integrally connected to the connector 107. The connecting protrusion 108 slides in contact with the arc-shaped guide groove 1061. When the connecting protrusion 108 slides in the arc-shaped guide groove 1061, it will cause the lifting plate 104 to rotate.

[0044] Therefore, in this application, when the lifting plate 104 moves downward along the guide rod 103, the lifting plate 104 rotates accordingly, thereby causing the brake pads to rotate while moving up and down, resulting in a good cleaning effect.

[0045] It should be added here that a first elastic element 109 is sleeved on the guide post 106. The first elastic element 109 abuts against the connector 107. The first elastic element 109 is preferably a spring. The first elastic element 109 can cause the connector 107 to return to its original position.

[0046] A limiting groove 1041 is formed on the lifting plate 104. The limiting groove 1041 is arc-shaped. A guide limiting member 110 is slidably disposed in the limiting groove 1041. The guide limiting member 110 has a limiting surface 112. The limiting surface 112 slides in contact with the limiting groove 1041, so that the limiting groove 1041 can move on the guide limiting member 110. The guide limiting member 110 has a locking contact surface 111. The locking contact surface 111 contacts the upper surface and the lower surface of the lifting plate 104, respectively. The guide rod 103 passes through the guide limiting member 110 and slides in contact with it.

[0047] In this application, the guide limiting member 110 can guide the up and down movement of the lifting plate 104 on the one hand, and limit the rotation of the lifting plate 104 on the other hand.

[0048] Considering that the lifting plate 104 needs to be separated from the cleaning chamber 101, the connecting member 107 is set to be separable; the connecting member 107 includes a rotating member one and a rotating member two. The rotating member one is provided with a rectangular cavity, and the rotating member two is provided with a rectangular protrusion that matches the rectangular cavity. Torque is transmitted through the rectangular cavity and the rectangular protrusion.

[0049] In actual use, the lifting mechanism 500 drives the lifting rod 113 to move. The lifting rod 113 contacts the lifting plate 104 and presses the lifting plate 104. The lifting mechanism 500 includes: a moving frame 501, a chain 1 502 and a chain 2 503 fixedly connected to the moving frame 501, a rotating shaft 504, and a motor. The motor drives the rotating shaft 504 to rotate, thereby driving the chain 1 502 and the chain 2 503 to move, so as to drive the moving frame 501 to move. The upper end of the lifting rod 113 is fixedly installed on the moving frame 501.

[0050] Guide rods can be installed between the movable frame 501 and the frame as needed to guide the movable frame 501 to move stably up and down.

[0051] The frame 100 is provided with a filter mechanism 600, which filters the ultrasonic cleaning fluid to remove impurities and adds ultrasonic cleaning agent.

[0052] The filtration mechanism 600 includes: a filter frame 601; a partition plate 602 and a support plate 603 fixedly installed inside the filter frame 601; a filter screen 604 embedded inside the support plate 603; a scraper 605 for removing impurities from the filter screen 604; and a feed pipe 606 for adding cleaning agent.

[0053] The filter frame 601 is provided with an inlet pipe 607 and an outlet pipe 608. The inlet pipe 607 is connected to the frame 100 through a first pipe, and the outlet pipe 608 is connected to the frame 100 through a second pipe. Pumps can be installed on the first pipe and the second pipe as needed to realize the flow of ultrasonic cleaning fluid.

[0054] A flow channel is provided between the lower end of the partition plate 602 and the support plate 603. The ultrasonic cleaning fluid flows through the flow channel to the top of the support plate 603, and after being filtered by the filter screen 604, it flows to the bottom of the support plate 603. The flow channel limits the height of the water flow to avoid the water flow being too concentrated, which would result in poor filtration effect.

[0055] When the scraper 605 moves along the water flow direction, it scrapes away impurities on the filter screen 604, cleaning the filter screen 604. When it moves in the opposite direction, the scraper 605 does not contact the filter screen 604, preventing impurities from accumulating on the filter screen 604. A connecting rod 609 is fixedly connected to the scraper 605. A fixing plate 610 is fixedly installed inside the filter frame 601. A limiting slide rail 6101 is provided on the fixing plate 610. A connecting protrusion 611 is fixedly connected to the connecting rod 609. The connecting protrusion 611 is slidably connected to the limiting slide rail 6101, that is, the connecting protrusion 611 slides within the limiting slide rail 6101.

[0056] The upper end of the connecting rod 609 is slidably connected to the power connecting rod 612. The upper end of the connecting rod 609 is inserted into the interior of the power connecting rod 612 and slides in contact with the power connecting rod 612. The power connecting rod 612 is connected to a leverless cylinder 613 that drives it to move, so that the power connecting rod 612 can drive the connecting rod 609 to move, and at the same time, the connecting rod 609 can move axially on the power connecting rod 612.

[0057] In this application, the limiting slide 6101 is composed of a first slide, a second slide, a first connecting slide, and a second connecting slide. The first slide is located above the second slide. The first connecting slide and the second connecting slide are used to connect the first slide and the second slide. When the connecting protrusion 611 slides in the second slide, the lower end of the scraper 605 contacts the filter screen 604, which can remove impurities on the filter screen 604. When the connecting protrusion 611 slides in the first slide, the lower end of the scraper 605 is above the filter screen 604, preventing impurities from flowing back.

[0058] The first and second connecting slides are U-shaped to facilitate the switching of slides.

[0059] In this invention, a feeding pipe 606 is connected to the power connecting rod 612. A dosing component 614 is slidably disposed inside the feeding pipe 606. A second elastic element 615 is disposed between the dosing component 614 and the feeding pipe 606. The dosing component 614 has a drug storage chamber inside. A contact element 616 is disposed at one end of the dosing component 614. A track 617 is disposed on the filter frame 601. The feeding pipe 606 is in slidable contact with the track 617. The contact element 616 is in contact with the side of the track 617. The side of the track 617 is curved. That is to say, when the power connecting rod 612 drives the feeding pipe 606 to move, the dosing component 614 will move accordingly. The side of the track 617 and the second elastic element 615 work together to make the dosing component 614 reciprocate.

[0060] It should be added here that the dosing tube is integrally connected to the discharge tube, and the dosing component 614 is provided with a connection hole. When the connection hole moves above the discharge tube, it becomes conductive, and the cleaning agent inside the dosing component 614 drips into the filtered ultrasonic cleaning liquid through the connection hole and the discharge tube, so as to increase the concentration of the cleaning agent.

[0061] In summary, when cleaning the brake pads, the ultrasonic cleaning fluid flows into the filter frame 601; the ultrasonic cleaning fluid flows through the flow channel to the top of the support plate 603, and after being filtered by the filter screen 604, it flows to the bottom of the support plate 603; during this process, when the scraper 605 moves along the water flow direction, it scrapes off impurities on the filter screen 604, cleaning the filter screen 604; when it moves in the opposite direction, the scraper 605 does not contact the filter screen 604, avoiding the accumulation of impurities on the filter screen 604; at the same time, the feeding pipe 606 drives the dosing component 614 to move, and the side of the track 617 and the second elastic member 615 work together to make the dosing component 614 move back and forth, achieving the purpose of adding concentrated ultrasonic cleaning fluid, ensuring uniform addition.
