[0030] Example:

[0031] like Figure 1 As shown, this utility model discloses a feeding device for irregularly shaped stamped parts, including a conveyor module 1 and a feeding robot 2. The main components of this utility model will be described in detail below:

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the conveyor module 1 includes a first conveyor belt 11, a second conveyor belt 12, and a third conveyor belt 13 arranged sequentially. The conveying speeds of the first conveyor belt 11, the second conveyor belt 12, and the third conveyor belt 13 increase sequentially and can be started and stopped independently. The third conveyor belt 13 is provided with a feeding detection photoelectric sensor 13a and two posture correction mechanisms 14 along the conveying direction. The posture correction mechanism 14 includes guide clamps 14a arranged opposite to each other on both sides of the conveying surface of the third conveyor belt 13. The guide clamps 14a on both sides open and close under the drive of the opening and closing drive 14b. The front ends of the guide clamps 14a on both sides can be closed to form a guide positioning groove for irregular stamping parts. A recognition photoelectric sensor 14c is provided on one side of the guide clamp 14a.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the front end of the loading robot 2 is provided with gripper mechanisms 21 in the same number as the posture correction mechanisms 14. The spacing between the gripper mechanisms 21 is the same as the spacing between the posture correction mechanisms 14. The loading robot 2 can drive the gripper mechanisms 21 to reciprocate above the guide plate 14a and in the loading area.

[0034] refer to Figure 1 , Figure 2 and Figure 3 As shown, the usage method and principle of this utility model are described below:

[0035] In use, the irregular stamped parts 4 are sent to the first conveyor belt 11 by a vibratory feeder. Then, the irregular stamped parts 4 are successively conveyed to the third conveyor belt 13 via the first conveyor belt 11 and the second conveyor belt 12. During this process, the conveying speed of the first conveyor belt 11, the second conveyor belt 12 and the third conveyor belt 13 increases in sequence, which gradually increases the interval between the irregular stamped parts 4.

[0036] Then, the irregularly shaped stamped part 4 is identified by the feeding detection photoelectric sensor 13a. The posture correction mechanism 14 at the front end of the third conveyor belt 13 opens the guide clamp 14a, and the posture correction mechanism 14 at the rear end of the third conveyor belt 13 closes the guide clamp 14a to form a guide positioning groove for the irregularly shaped stamped part. Under the action of the friction force on the surface of the third conveyor belt 13, the irregularly shaped stamped part 4 enters the guide positioning groove for the irregularly shaped stamped part and completes the positioning. After the irregularly shaped stamped part 4 passes the posture correction mechanism 14 at the front end of the third conveyor belt 13, it is identified. The photoelectric sensor 14c identifies the part, and then the attitude correction mechanism 14, located at the front end of the third conveyor belt 13, closes the guide clamp 14a to form a guide positioning groove for the irregular stamping part. Then, the irregular stamping part 4 enters the guide positioning groove for the irregular stamping part under the action of the friction force on the surface of the third conveyor belt 13 to complete the positioning. During this process, the feeding detection photoelectric sensor 13a will monitor the feeding quantity of the irregular stamping part 4. When the feeding quantity of the irregular stamping part 4 is sufficient, the second conveyor belt 12 will be stopped to avoid the irregular stamping part 4 from accumulating and bumping.

[0037] After the attitude correction mechanism 14 corrects and positions the irregular stamping part 4, the loading robot 2 drives the gripper mechanism 21 to move to the irregular stamping part 4. Since the number and spacing of the gripper mechanism 21 are the same as the number and spacing of the attitude correction mechanism 14, the loading robot 2 can simultaneously position and grip the two irregular stamping parts 4 through the gripper mechanism 21. After gripping, the irregular stamping part 4 is moved to the loading area for positioning and loading through the loading robot 2 and the gripper mechanism 21. The loading accuracy and efficiency are high.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, in order to improve the feeding efficiency, the conveyor module 1 is provided with two sets. The two sets of conveyor modules 1 are arranged in parallel along their conveying direction. Several gripper mechanisms 21 are arranged in two parallel and symmetrical rows on the feeding robot 2. The two rows of gripper mechanisms 21 are used to position, grip and feed the irregular stamped parts 4 on the two sets of conveyor modules 1 respectively.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, in order to improve the feeding accuracy, the gripper mechanisms 21 are all set on the fixed base 22. The fixed base 22 is detachably connected to the front end of the feeding robot 2. The gripping end of the gripper mechanism 21 is provided with a contour positioning groove 21a.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, to improve the conveying control accuracy, the first conveyor belt 11, the second conveyor belt 12, and the third conveyor belt 13 are all driven by servo motors.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, in order to facilitate the control of the conveying quantity of irregular stamped parts, the first conveyor belt 11 is provided with a number of first positioning detection photoelectric sensors 11a, and the second conveyor belt 12 is provided with a number of second positioning detection photoelectric sensors 12a.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, in order to avoid the accumulation of irregularly shaped stamped parts on the conveyor module, the end of the third conveyor belt 13 is connected to a collection box 3 to send excess irregularly shaped stamped parts 4 into the collection box 3.

[0043] like Figure 1 , Figure 2 and Figure 3 As shown, to ensure the corresponding speed of the guide clamp's movement, the opening and closing drive 14b is a cylinder.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, the guide plate 14a and the opening / closing drive 14b are detachably connected for easy model switching.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, in order to facilitate the connection between the conveyor module and external equipment, the lower end of the conveyor module 1 is provided with a liftable fixing frame 15.

[0046] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
