Description

Technical Field

[0001] This utility model relates to the field of circuit board processing, and in particular to a discharge device for a board receiving machine. Background Technology

[0002] After the circuit boards are collected by the board collecting machine, they are evenly spaced and inserted into the racks. Some racks have circuit boards arranged vertically, with both ends extending out of the rack to accommodate circuit boards of various sizes. After collection, the racks containing multiple circuit boards are conveyed to the next workstation via a conveyor belt. However, after prolonged use under load, the conveyor belt inevitably deforms, causing it to vibrate and deviate. This vibration also causes the circuit boards inside the racks to fall off. During the movement of the racks to the next workstation (e.g., processing equipment or transfer vehicle), a gap exists between the next workstation and the conveyor belt. Due to the vibration of the conveyor belt, one end of the rack may shift vertically or horizontally within this gap, preventing proper alignment for loading. When loading or unloading fails, the circuit boards may collide within the rack or fall off, further damaging them. Utility Model Content

[0003] This utility model provides a discharge device for a board receiving machine, which can transport a rack with multiple circuit boards inserted vertically, and improves the accuracy of the rack during transport, avoiding lateral or vertical displacement of the rack on the conveyor belt. At the same time, it ensures that the rack can smoothly pass through the gap between the conveyor belt and the next station, so as to accurately deliver the rack to the next station.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a discharge device for a plate collecting machine, used for conveying a material rack, comprising: a support, a drive mechanism, and infeed / discharge components. The drive mechanism is disposed at the lower end of the support. Two sets of infeed / discharge components are symmetrically disposed on the support. Each set of infeed / discharge components includes a first roller, a conveying mechanism, and a transition mechanism. The conveying mechanism and the transition mechanism are sequentially disposed on the support along the conveying direction of the material rack. The conveying mechanism is tractively connected to the drive mechanism. The first roller is rotatably disposed at the upper end of the support and is disposed diagonally above the conveying mechanism. The transition mechanism includes a bearing seat, a second roller, and an end roller. One end of the bearing seat is detachably disposed on the support. The end roller is rotatably disposed at the other end of the bearing seat. The second roller is rotatably disposed at the upper end of the bearing seat. The axes of the first roller and the second roller are both vertically disposed. The conveying direction of the conveying mechanism and the axis of the end roller are both horizontally disposed. The conveying direction of the conveying mechanism and the axis of the end roller are perpendicular to each other. The transition mechanism fills the gap between the conveying mechanism and the next station, ensuring that the material rack is stably conveyed to the next station and preventing one end of the material rack from falling below the gap.

[0005] Preferably, the discharge device further includes two buffer blocks, which are symmetrically arranged at one end of the support and directly below the second roller. The buffer blocks are used to abut against the next station, limiting the distance between the transition mechanism and the next station to ensure that the distance between the transition mechanism and the next station is small enough to meet the requirements for smooth passage of the material rack.

[0006] Preferably, the bracket has symmetrically formed grooves, and the bearing seats are detachably disposed inside the grooves one by one. The width of the bearing seat is less than the depth of the groove, and the bearing seat and the inside of the groove are detachably connected by fasteners.

[0007] Preferably, both sets of the feeding and discharging components also include a guide element, which is detachably mounted on the upper end of the bracket, and the first roller and the guide element are both mounted obliquely above the conveying mechanism.

[0008] Preferably, the upper end of the guide element is provided with a guide groove, and the material rack is provided with ribs on both sides, the ribs passing through the guide groove.

[0009] Preferably, the material rack includes a base, a fixing plate, and a frame strip for separating adjacent products. The fixing plate is disposed at both ends of the base, and the frame strip is disposed at both ends of the base. The frame strip passes through the end of the fixing plate near the base, and the end of the fixing plate away from the base forms the protruding rib.

[0010] Preferably, the guide element is disposed between two adjacent first rollers.

[0011] Preferably, the guiding element includes a guide block and a connecting plate, and the guide block, the connecting plate and the bracket are detachably connected from top to bottom, and the connecting plate is a horizontal plate or an inverted L-shaped block.

[0012] Preferably, the conveying mechanism includes a first pulley, a second pulley, and a conveyor belt. The support is rotatably provided with a first rotating shaft. The first pulley is detachably mounted on the first rotating shaft. The second pulley is rotatably connected to the support. The first pulley and the second pulley are connected by a conveyor belt. A support plate is fixedly provided inside the support. The support plates are fitted one-to-one inside the conveyor belt. The upper surface of the support plate is in contact with the upper end of the conveyor belt.

[0013] Preferably, the bracket is rotatably provided with a second rotating shaft, the second pulley is detachably disposed on the second rotating shaft, the second pulley and the bracket are rotatably connected through the second rotating shaft, the first rotating shaft and the second rotating shaft are both spline shafts, and the first pulley and the second pulley are detachably disposed on the first rotating shaft and the second rotating shaft respectively by set screws.

[0014] The beneficial effects of this invention are as follows: the first and second rollers clamp the material rack from both sides, preventing it from moving left or right. The protruding ribs of the material rack pass sequentially through the guide grooves of each guide element, positioning the material rack to prevent it from bouncing up and down. This improves the accuracy of the material rack during conveying, preventing left-right or up-down displacement on the conveyor belt, thus facilitating the precise delivery of material racks with multiple circuit boards vertically inserted to the next workstation.

[0015] During use, the buffer block will be inserted below the next station, and the end of the transition mechanism will be close to the next station. The transition mechanism will fill the gap between the conveyor belt and the next station. The material rack is conveyed by the second roller and the end roller, ensuring that the material rack can be smoothly conveyed into the gap between the conveyor mechanism and the next station, so as to accurately deliver the material rack to the next station.
