[0017] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.
[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.
[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.
[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0022] Please see Figure 1 , Figure 2 and Figure 5 This utility model provides a multi-station brake pad painting equipment, including: a frame assembly 3, multiple brake pad tray assemblies 1, and a spray gun assembly 2; wherein, the frame assembly 3 includes a fixed frame 304 and a rotating frame 301, the rotating frame 301 is rotatably arranged relative to the fixed frame 304, and the rotating frame 301 can be a ring rotating frame; multiple brake pad tray assemblies 1 are arranged at intervals on the rotating frame 301 along the rotation direction of the rotating frame 301, that is, evenly distributed along the circumference of the ring rotating frame, and the rotating frame 301 has multiple installation stations, specifically two, three, four, five, six, or more, and one brake pad tray assembly 1 is installed on each installation station. The brake pad tray assembly 1 is driven to rotate relative to the fixed frame 304 by the rotating frame 301. The brake pad tray assembly 1 is used to fix the brake pad 100. The spray gun assembly 2 is set on the fixed frame 304 and is used to spray paint the area to be painted on the brake pad 100 that has been rotated to the position of the spray gun assembly 2. The area to be painted on the brake pad 100 can be the side of multiple friction bodies 1002 located on the same side of the brake pad.
[0023] When using this multi-station brake pad painting equipment, the operator first clamps and fixes multiple brake pads 100 to be painted onto multiple brake pad tray assemblies 1. After clamping, the multiple brake pad tray assemblies 1 are arranged at intervals along the rotation direction of the rotating frame 301 and fixed on the rotating frame 301. At this time, the rotating frame 301 rotates relative to the fixed frame 304 by one station angle, so that the brake pad tray assembly 1 with clamped brake pads 100 reaches the painting station, and at the same time, the next brake pad tray assembly 1 without clamped brake pads 100 is sent to the clamping / removing brake pad station. When the brake pad 100 stops at the painting station, the spray gun assembly 2 fixed on the fixed frame 304 immediately starts to automatically paint the stationary brake pad 100. While the painting operation is in progress, the operator can remove the painted brake pads 100 and clamp new brake pads 100 on the brake pad tray assemblies 1 that are not in the painting station. After the painting is completed, the rotating frame 301 rotates another station angle to start the next work cycle, realizing continuous production.
[0024] As can be seen from the above scheme and specific implementation process, the multi-station brake pad painting equipment provided by this utility model realizes multi-station painting operations through the combination of the rotating frame 301 and multiple brake pad tray assemblies 1, significantly improving work efficiency. The fixed frame 304 provides a stable fixed foundation for the equipment, ensuring structural stability during operation, and also provides an installation support point for the spray gun assembly 2. The rotating frame 301, by rotating relative to the fixed frame 304, drives the brake pad tray assembly 1 to rotate, providing a structural foundation for continuous multi-station operation and further improving work efficiency. The brake pad tray assembly 1 is a fixing device for the brake pad 100, fixing the brake pad 100 to be painted and preventing displacement of the brake pad 100 during movement or painting, which would affect the painting quality. When the brake pad 100 rotates to the position of the spray gun assembly 2, the spray gun assembly 2 can accurately spray paint onto the area of the brake pad 100 to be painted, ensuring consistent painting quality.
[0025] like Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, in some embodiments, the brake pad tray assembly 1 includes a brake pad support plate 101 and a brake pad baffle 102; the brake pad support plate 101 is fixedly installed on the rotating frame 301, and one side of the brake pad support plate 101 is provided with a dovetail groove 1012 and a first limiting structure 1011. The dovetail groove 1012 is used to cooperate with the dovetail 1003 of the brake pad 100 for installation, and the dovetail 1003 can be pushed into the dovetail groove 1012 in a direction parallel to one side of the brake pad support plate 101. The first limiting structure 1011 is used to limit contact with the edge of the steel back 1001 of the brake pad 100; the brake pad baffle 102 is fixed to the side of the brake pad support plate 101 with the dovetail groove 1012, and the brake pad baffle 102 has a second limiting structure 1021 for limiting contact with the side of the friction body 1002 of the brake pad 100. The brake pad tray assembly 1 achieves rapid installation of the brake pad 100 through the precise engagement of the dovetail groove 1012 and dovetail 1003 on the brake pad tray plate 101. The first limiting structure 1011 makes limiting contact with the edge of the steel backing 1001, and together with the second limiting structure 1021 on the brake pad baffle 102 limiting the side of the friction body 1002, they jointly limit and fix the brake pad 100, ensuring that the brake pad 100 remains fixed and precisely positioned during the rotation of the rotating frame 301 and the painting process. In addition, the first limiting structure 1011 also shields the side area of the steel backing 1001, and the second limiting structure 1021 can shield the area of the steel backing 1001, preventing painting of non-painted areas of the brake pad 100.
[0026] like Figure 3 and Figure 6As shown, in some embodiments, the brake pad tray assembly 1 includes two brake pad support plates 101 and two brake pad baffles 102. The brake pad tray assembly 1 also includes multiple support tubes 104, multiple bolts 103, and multiple nuts 105. The sides of the two brake pad support plates 101 with dovetail grooves 1012 are arranged opposite each other and symmetrically. The two brake pad baffles 102 are arranged in a one-to-one correspondence with the two brake pad support plates 101. The support tubes 104 are supported between the two opposing brake pad baffles 102. The bolts 103 are used to pass through the brake pad support plates 101, brake pad baffles 102, and support tubes 104 and are then fixed by nuts 105 to symmetrically stack and fix the two brake pads 100, and the friction bodies 1002 of the two brake pads 100 are in contact. Two brake pad support plates 101, with their dovetail grooves 1012 facing each other and symmetrically arranged, cooperate with two brake pad baffles 102 that correspond one-to-one with the two brake pad support plates 101, ensuring that the two brake pads 100 can be symmetrically installed in a stacked manner, improving production efficiency. Furthermore, the friction surfaces 1002 of the two brake pads 100 are in direct contact, effectively preventing paint from being applied to the friction surfaces of the friction surfaces 1002 during the painting process. Support tubes 104 provide support for the two brake pad support plates 101, ensuring stability. The tightening method of bolts 103 and nuts 105 ensures the fixation of the two brake pad support plates 101, the two brake pad baffles 102, and the two brake pads 100. The overall structural design improves production efficiency while ensuring stability during production. For example, four support tubes 104 are located at the corners of the brake pad support plates 101, ensuring that the clamping and disassembly of the brake pads 100 are not obstructed while maintaining stability.
[0027] like Figure 1 and Figure 3 As shown, in some embodiments, the side of the brake pad support 101 with the first limiting structure 1011 is closer to the rotation center of the rotating frame 301 than the other side. By aligning the side of the brake pad support 101 with the first limiting structure 1011 towards the rotation center of the rotating frame 301, the clamping and disassembly operations of the brake pads at all workstations are directed towards the outside of the rotating frame 301, providing ample operating space for the operator. Of course, the side of the brake pad support 101 with the first limiting structure 1011 can also face the outside of the rotating frame 301.
[0028] like Figure 6 , Figure 7 and Figure 8As shown, in some embodiments, the first limiting structure 1011 is a limiting groove formed on one side of the brake pad support plate 101, and the limiting groove matches the shape of one side edge of the steel backing plate 1001; the second limiting structure 1021 is a limiting curved surface formed on the brake pad baffle 102, and the limiting curved surface matches the side shape of the multiple friction bodies 1002 located on the same side of the brake pad 100. The limiting groove formed on the brake pad support plate 101 that matches the edge shape of the steel backing plate 1001 serves as the first limiting structure 1011, which, while achieving rapid positioning, also forms a shielding effect on the side of the steel backing plate 1001; the limiting curved surface formed on the brake pad baffle 102 that matches the side shape of the friction bodies 1002 serves as the second limiting structure 1021, which, while fixing the brake pad 100, also forms a shielding effect on the surface of the steel backing plate 1001. This structure simultaneously achieves shielding of non-painted areas during the clamping and positioning process, effectively preventing contamination of the side and surface of the steel backing plate 1001. Of course, the first limiting structure 1011 and the second limiting structure 1021 can also be limiting pillars, limiting blocks, or other structures that play a limiting role, and are not limited to the forms listed in this embodiment.
[0029] like Figure 1 and Figure 4 As shown, in some embodiments, the spray gun assembly 2 includes: a first moving mechanism for moving in a first horizontal direction, a second moving mechanism for moving in a second horizontal direction, and a spray gun 200; the first moving mechanism is disposed on the fixed frame 304; the second moving mechanism is disposed on the first moving mechanism, and the first and second horizontal directions intersect; the spray gun 200 is disposed on the second moving mechanism and is used to spray paint onto the area to be painted on the brake pad. Through the coordinated operation of the first and second moving mechanisms in the intersecting horizontal directions, the spray gun 200 can move freely in the plane, avoiding paint dead angles caused by a single moving direction. Based on the shape of the area to be painted on the brake pad 100, the first moving mechanism and the second moving mechanism adjust the distance between the spray gun 200 and the area to be painted on the brake pad 100 to maintain equidistant spacing, thereby improving the uniformity of paint spraying on the brake pad 100. Figure 9 The distance between the trajectory of the spray gun 200 and the side of the friction body 1002 on the same side remains equidistant.
[0030] like Figure 4As shown, in some embodiments, the first moving mechanism includes a first lead screw guide rail 201, a first drive motor 2021, and a first guide rail slider 2031. The first lead screw guide rail 201 is fixedly connected to the fixed frame 304 and is driven by the first drive motor 2021. The first guide rail slider 2031 is slidably connected to the first lead screw guide rail 201 along a first horizontal direction. The fixed connection of the first lead screw guide rail 201 to the fixed frame 304 provides a stable foundation for the first moving mechanism. The guide rail mechanism of the first lead screw guide rail 201 itself provides a sliding path for the first guide rail slider 2031, restricting its movement only along the first horizontal direction. The first drive motor 2021 provides power to the first moving mechanism. Of course, the first moving mechanism can also be a drive cylinder, such as a hydraulic cylinder, pneumatic cylinder, or other mechanism capable of linear movement.
[0031] like Figure 4 As shown, in some embodiments, the second moving mechanism includes a second lead screw guide rail 204, a second drive motor 2022, and a second guide rail slider 2032. The second lead screw guide rail 204 is fixedly connected to the first guide rail slider 2031, driven by the second drive motor 2022, and the second guide rail slider 2032 is slidably connected to the second lead screw guide rail 204 along a second horizontal direction. The second lead screw guide rail 204, fixedly connected to the first guide rail slider 2031, can achieve movement in the first horizontal direction with the help of the first guide rail slider 2031, and can also provide a path for the second guide rail slider 2032 to move along the second horizontal direction according to its own guide rail structure. The second drive motor 2022 provides power to the second moving mechanism. For example, the first lead screw guide rail 201 and the second lead screw guide rail 204 can be placed vertically. Of course, the second moving mechanism can also be a drive cylinder, such as a hydraulic cylinder, pneumatic cylinder, or other mechanism capable of linear movement.
[0032] like Figure 4As shown, in some embodiments, the spray gun assembly 2 further includes a rotating mechanism; the rotating mechanism includes a spray gun bracket 205, a rotating rod 206, a gear 207, a gear belt 208, and a third drive motor 209; the spray gun bracket 205 is fixedly connected to the moving end of the second moving mechanism; the third drive motor 209 is disposed on the spray gun bracket 205, and the rotating rod 206 is rotatably disposed on the spray gun bracket 205, the axis of the rotating rod 206 may be perpendicular to the first horizontal direction and the second horizontal direction; the third drive motor 209 and the rotating rod 206 are respectively provided with gears 207, and the two gears 207 are connected by a gear belt 208; one end of the rotating rod 206 is fixedly connected to a spray gun 200. The spray gun 200, connected to a rotating mechanism, enhances the flexibility of its spraying angle. The spray gun holder 205 provides a stable base for the rotating mechanism. The third drive motor 209, through a transmission system consisting of gears 207 and a gear belt 208, transmits power to the rotating rod 206, driving the spray gun 200, fixed to the end of the rotating rod 206, to achieve multi-angle spraying. This effectively eliminates the blind spots present at fixed angles, ensuring the uniformity of paint application on the brake plate 100. For example, the spray gun holder 205 is fixedly connected to the second guide rail slider 2032, enabling the spray gun 200 to perform multi-directional spraying operations.
[0033] like Figure 5 As shown, in some embodiments, the test bench assembly 3 further includes a rotating frame support plate 302, a bearing gear ring 303, a test bench gear 305, a fourth drive motor 306, and a power control box 307; wherein, the rotating frame support plate 302 is disposed at the bottom of the rotating frame 301, the bearing gear ring 303 is disposed at the bottom of the rotating frame support plate 302, the bearing gear ring 303 meshes with the test bench gear 305, the test bench gear 305 is connected to the fourth drive motor 306, the fourth drive motor 306 is disposed on the fixed frame 304; the power control box 307 is used for power control. A rotating frame support plate 302 is located at the bottom of the rotating frame 301, and its rotation drives the rotating frame 301 to rotate simultaneously. A bearing gear ring 303 is located at the bottom of the rotating frame support plate 302, and its rotation drives the rotating frame support plate 302 to rotate simultaneously. The bearing gear ring 303 meshes with a frame gear 305, which is connected to a fourth drive motor 306. The coordinated action of these components converts the power of the fourth drive motor 306 into the rotational motion of the rotating frame 301. The power control box 307 is responsible for the power control of the equipment and provides power support to the fourth drive motor 306 and other electrical components. This achieves automatic rotation of the rotating frame, saving manpower; however, the rotating frame can also be manually driven.
