[0020] The following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not used to limit the present utility model.
[0021] Please refer to Figure 1 - Figure 2 Figure 1 It is a three - dimensional structural schematic diagram of the automatic feeding device provided by an embodiment of the present utility model arranged on one side of the CNC milling machine; Figure 2 It is a partial three - dimensional structural schematic diagram of the automatic feeding device provided by an embodiment of the present utility model. The automatic feeding device 1 for the CNC milling machine of the present utility model includes a conveying assembly, a storage bin 14, and a lifting assembly. The conveying assembly includes a conveyor belt 11, a deflector 12, a diverter plate 13, and a diverter driving member. The deflector 12 is arranged above the conveyor belt 11 and divides the conveyor belt 11 into at least two conveying channels. The diverter plate 13 is hinged to the deflector 12, and the diverter driving member is connected to the diverter plate 13 to drive the diverter plate 13 to swing within the conveying channel. The storage bin 14 is arranged on one side of the conveying assembly. One end of the lifting assembly is located inside the storage bin 14, and the other end is close to the conveyor belt 11 to lift the parts in the storage bin 14 onto the conveyor belt 11.
[0022] During the part conveying operation, by pouring the parts into the storage bin 14, the parts are lifted from the storage bin 14 onto the conveyor belt 11 under the action of the lifting assembly, and then the conveyor belt 11 conveys the parts. Under the action of the deflector 12, the parts are divided into different conveying channels for conveyance, and under the drive of the diverter driving member on the diverter plate 13, the diverter plate 13 swings within the conveying channel, so as to divert the parts from one conveying channel to another, thereby realizing the control of the part flow rate on multiple conveying channels and avoiding the phenomenon of machine jamming caused by part congestion on the conveying channel.
[0023] In the above embodiments, the conveyor belt 11 uses intermittent transmission when conveying parts, so that when the conveyor belt 11 stops transmitting, the operator can take out the parts from the conveyor path and place them on the CNC milling machine 2 for processing operations. After the operator takes out the parts from the conveyor path, the conveyor belt 11 makes one transmission and then stops transmitting again, thus facilitating the operator to take parts from the conveyor path for processing, eliminating the need for the operator to stack and arrange the parts manually, reducing the labor intensity of the operator, and improving the part processing efficiency.
[0024] Since there are at least two conveyor paths provided, the operator can take out at least two parts from the conveyor path at one time and cooperate with the multi-station fixture in the CNC milling machine 2 to clamp and fix at least the parts, so as to facilitate the CNC milling machine 2 to perform part processing operations on at least two parts at the same time, further improving the processing efficiency.
[0025] The shunt driving member adopts a motor to drive the shunt plate 13 to swing in the conveyor path under the drive of the motor, so as to avoid the phenomenon of machine jamming caused by uneven distribution of parts on the conveyor path.
[0026] In an embodiment of the present invention, a camera 15 is provided on the guide plate 12. The camera 15 directly faces the conveyor belt 11 to take images and identify the direction of the parts. The shunt driving member is electrically connected to the camera 15, so that the shunt driving member drives the shunt plate 13 to divert the parts according to the direction of the parts.
[0027] By installing the camera 15 on the guide plate 12, the camera 15 can take real-time images of the parts on the conveyor path and identify the part direction according to the part characteristics, that is, identify whether the current part is face up or face down. Furthermore, after the camera 15 identifies the part direction, the shunt driving member can be triggered to drive the shunt plate 13 to swing to the corresponding position to divert parts in different directions in the correct direction, so that the part directions in the same conveyor path are all the same, facilitating the operator to take the parts on the conveyor path and directly place them on the CNC milling machine 2 for processing, without the need to turn over the parts, and improving the part processing efficiency.
[0028] In an embodiment of the present invention, the number of the cameras 15 is equal to the number of the conveyor paths. Two shunt plates 13 are spaced apart on the guide plate 12. The positions of the cameras 15 correspond to the positions of the shunt plates 13. When the conveyor belt 11 conveys the parts, the cameras 15 corresponding to each conveyor path above can identify the part directions, and the shunt driving member is used to control the shunt plates 13 to swing, ensuring that the part directions in the same conveyor path can be kept consistent, facilitating the operator to take the parts for processing operations, and increasing the flexibility and adaptability of the device.
[0029] In an embodiment of the present utility model, the number of the flow guiding plates 12 is at least two. At least two flow guiding plates 12 divide the conveyor belt 11 into at least three conveying channels. The conveying channels include a front conveying channel and a reverse conveying channel, and the front conveying channel and the reverse conveying channel are distributed at intervals from each other.
[0030] Through the arrangement of at least two flow guiding plates 12, the conveyor belt 11 is divided into at least three conveying channels, so as to facilitate the conveying of parts on at least three conveying channels, and under the action of the flow dividing plate 13, the parts in the same direction are guided to the same conveying channel, which is convenient for the operator to pick up the parts for processing operations, and increases the flexibility and adaptability of the device.
[0031] In an embodiment of the present utility model, the number of the flow guiding plates 12 is five. Five flow guiding plates 12 divide the conveyor belt 11 into four conveying channels. Among them, two front conveying channels and two reverse conveying channels are distributed at intervals from each other, so as to guide the parts in the same direction to the same conveying channel under the action of the flow dividing plate 13. Specifically, the parts with the front side facing up are guided to the front conveying channels, that is, the parts with the front side facing up are guided to the first conveying channel and the third conveying channel, and the parts with the reverse side facing up are guided to the reverse conveying channels, that is, the parts with the reverse side facing up are guided to the second conveying channel and the fourth conveying channel, so that the automatic feeding device can clamp at least two parts from the front conveying channel and put the parts into the CNC milling machine 2 for part processing. And when feeding next time, the automatic feeding device clamps at least two parts from the reverse conveying channel and puts the parts into the CNC milling machine 2 for part processing, improving the part processing efficiency.
[0032] In an embodiment of the present utility model, the lifting assembly includes a lifting driving member, a sprocket, a chain and a bearing plate 16. The bearing plates 16 are arrayedly installed on the chain to carry parts. The sprockets are respectively rotatably connected to the top and bottom of the storage bin 14 for installing the chain. The lifting driving member is connected to one of the sprockets to drive the chain to drive the bearing plate 16 to move.
[0033] After the operator pours the parts into the storage bin 14, the lifting driving member drives the sprocket to rotate, so that the rotating sprocket drives the chain to rotate, and then the chain drives the bearing plate 16 to move, so that the bearing plate 16 transfers the parts in the storage bin 14 to the conveyor belt 11 to realize the automatic transmission of the parts. Among them, the width dimension of the bearing plate 16 is adapted to the dimension of the parts, so that only one part can be carried at the same position of the same bearing plate 16, avoiding the situation of parts stacking on the bearing plate 16. The length dimension of the bearing plate 16 is adapted to the length dimension of the storage bin 14, so that multiple parts are carried at different positions of the same bearing plate 16, so as to transfer multiple parts to the conveyor belt 11 in one lifting process, improving the lifting efficiency of the parts.
[0034] In an embodiment of the present utility model, the conveying assembly further includes a support rod and a height-limiting rod 17. The support rod is disposed on both sides of the conveyor belt 11 and connected to the deflector 12. The height-limiting rod 17 is installed on the support rod and forms a part passage with the conveyor belt 11 to achieve the interception of parts under the action of the height-limiting rod 17. That is, when the carrier plate 16 transfers parts to the conveyor belt 11 and there are stacked parts, when the conveyor belt 11 conveys the stacked parts to the position of the height-limiting rod 17, the height-limiting rod 17 scrapes the stacked parts onto the conveyor belt 11, so as to facilitate the conveyor belt 11 to convey the parts and at the same time facilitate the subsequent diverter 13 to divert the parts.
[0035] In an embodiment of the present utility model, the conveying assembly further includes a height adjusting member. The height adjusting member is installed on the deflector 12 and connected to the height-limiting rod 17 to drive the height-limiting rod 17 to adjust its height on the support rod, thereby allowing the distance between the conveyor belt 11 and the height-limiting rod 17 to be adjusted according to the part size, realizing the adjustment of the part passage, so that the height-limiting rod 17 conveys parts of different sizes, and improving the use flexibility of the automatic feeding device 1.
[0036] In the above embodiment, the height adjusting member adopts a motor to drive the height-limiting rod 17 to lift along the height-limiting rod 17 under the drive of the motor, thereby realizing the adjustment of the height of the part passage.
[0037] In other embodiments of the present utility model, the height adjusting member is a screw rod. The screw rod passes through the deflector 12 and is rotatably connected to the deflector 12, and the screw rod is threadedly connected to the height-limiting rod 17, so that an operator can manually adjust the screw rod to realize the height adjustment of the height-limiting rod 17. The operation is simple and convenient for precise adjustment of the height position.
