DETAILED DESCRIPTION

[0020] like Figure 1 and Figure 2The feed mechanism of a circuit board cleaning machine shown includes a feed streamline for conveying materials. The feed streamline includes multiple groups of conveyor rollers 1 arranged along the extension direction of the feed streamline. At least one group of guide rollers 2 is arranged above the feed streamline. The conveyor rollers 1 are driven to rotate by a conveying drive mechanism to provide transmission power for the materials. The guide rollers 2 can assist in the transfer of materials and form a feed channel between the guide rollers 2 and the conveyor rollers 1. During the material transmission process, a certain amount of tight pressure is applied to the conveyor rollers 1, so that the materials maintain contact with the surface of the conveyor rollers 1, and the materials can be smoothly conveyed to the cleaning machine. Multiple groups of rollers 3 are arranged on the roller bodies of the conveyor rollers 1 and the guide rollers 2, respectively, and the materials are transmitted by the rotation of the rollers 3. In this embodiment, the rollers 3 on adjacent conveyor rollers 1 are arranged at intervals, which increases the compactness of the conveyor rollers 1 while ensuring the transmission capacity of the conveyor rollers 1 and reduces the space occupied by the conveyor rollers 1.

[0021] like Figure 2 and Figure 3 As shown, the guide roller 2 and the conveying roller 1 of the utility model are positioned by relying on a fixed component, and the fixed component includes a supporting side plate 4 fixedly installed on both sides of the feed flow line, and the supporting side plate 4 has multiple groups of mounting grooves 5 arranged along the extension direction of the feed flow line, and each group of mounting grooves 5 is installed with a holder 6, and each group of holders 6 includes an upper holder 7 and a lower holder 8 set in the vertical direction, and the openings of the upper holder 7 and the lower holder 8 extend out of the surface of the holder 6. The conveying roller 1 and the guide roller 2 are correspondingly installed into the openings of the upper holder 7 and the lower holder 8, so as to limit the installation position of the conveying roller 1 and the guide roller 2.

[0022] The conveying drive mechanism of this embodiment adopts a gear transmission structure, such as Figure 1 and Figure 4 As shown, it includes a rotating main roller 9 extending along the side of the supporting side plate 4, and the rotating main roller 9 is driven to rotate by a servo motor. A plurality of sets of active bevel gears 10 are arranged at intervals along the roller body of the rotating main roller 9, and a driven bevel gear 11 meshing with the active bevel gear 10 is provided at the end of the conveying roller 1. The rotation stroke of the rotating main roller 9 is converted into the rotation stroke of each conveying roller 1 through the cooperation of the two sets of bevel gears.

[0023] To enhance the compactness of the transmission mechanism, in this embodiment, each pair of conveyor rollers 1 utilizes a bevel gear meshing module for transmission. Spur gears 12 are located at the ends of adjacent conveyor rollers 1, each utilizing this meshing module for transmission. Similarly, the conveyor rollers 1 and guide rollers utilize a spur gear meshing module, with spur gears 13 located at corresponding ends of the conveyor rollers 1 and guide rollers to transmit rotational travel.

[0024] The supporting side panels 4 of this embodiment are made of metal and can be secured to the cleaning machine frame by welding, providing basic support for the entire mounting assembly. The retaining bracket 6 is made of a rubber material with a certain degree of plasticity and hardness and is elastically snapped into the mounting slot 5. When the conveyor roller 1 is installed in the mounting slot 5, it is positioned between the bottom of the mounting slot 5 and the lower retaining edge 8 of the retaining bracket 6, limiting the rotational position of the conveyor roller 1.

[0025] Furthermore, a bearing ring 14 is provided between the bottom of the mounting groove 5 and the lower opening 8 of the holder 6 , and the end of the conveyor roller 1 is installed in the bearing ring 14 to reduce the influence of the groove wall of the mounting groove 5 on the rotation of the conveyor roller 1 .

[0026] The guide roller 2 is installed in the upper opening 7 of the holder 6. The position of the guide roller 2 can be adjusted arbitrarily by cooperating with the upper opening 7. When the material passes through, the guide roller 2 can move slightly along the upper opening 7 according to the different sizes of the materials, and automatically adjust the position between it and the conveying roller 1.

[0027] like Figure 1 As shown, a feed detection mechanism is also provided on the feed side of the guide roller 2, and the feed detection mechanism includes a detection bracket 15 and a feed detector 16 installed at the bottom of the detection bracket 15, wherein the two ends of the detection bracket 15 are clamped in at least two groups of upper clamping openings 7 of the clamping base 6, and the feed detection mechanism can be installed at any position of the feed flow line by clamping.

[0028] The assembly process of this embodiment is as follows: the supporting side plate 4 is fixedly connected to the feed side of the cleaning machine, and the bearing ring 14 and the conveying roller 1 are sequentially installed in the mounting groove 5, so that each conveying roller 1 and the rotating main roller 9 are engaged and transmitted; the holder 6 is installed in the mounting groove 5 to fix the position of each conveying roller 1, and then the guide roller 2 is installed into the upper clamping mouth 7 at a suitable position and engaged and transmitted with the conveying roller 1.

Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
