DETAILED DESCRIPTION

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] Example

[0021] like Figure 1-3 As shown, a deviation correction device for patch discharging includes a feed seat 11, a plurality of parallel material receiving troughs 1 are provided on the feed seat 11, a pressing rod 2 is provided at the end of the material receiving trough 1, and a material ejecting mechanism 3 corresponding to the plurality of material receiving troughs 1 is provided at the lower end of the pressing rod 2, a plurality of conveying rollers 4 are provided in the material receiving trough 1, and a plurality of conveying rollers 4 are provided with deviation correction rollers 5 at the front ends away from the material ejecting mechanism 3, and the plurality of deviation correction rollers 5 are connected by a connecting rod 6, and adjusting bolts 7 are provided at both ends of the connecting rod 6.

[0022] The two ends of the pressing rod 2 are connected to the feeding seat 11 through the bracket 8. The pressing rod 2 is provided with a plurality of pressing rollers 21. The plurality of pressing rollers 21 rotate independently of the pressing rod 2. The ejecting mechanism 3 includes a micro cylinder 31 and a cam 32. A swing arm 33 connected to the cam 32 is provided on one side. After the micro cylinder 31 is ejected upward, the swing arm 33 changes its tilt chamfer, so that the cam 32 connected to the swing arm 33 rotates. After the protruding part of the cam 32 rotates, it abuts against the upper end. The patch material strip, one end of the swing arm 33 is connected to the piston end of the micro cylinder 31 through the rotating shaft 34, the rotating shaft 34 drives the swing arm 33 to rotate, the cam 32 is located in the material receiving trough 1, and the upper end of the cam 32 is arranged corresponding to the pressing rod 2, and the piston end of the micro cylinder 31 is provided with a sleeve rod 35, and the sleeve rod 35 is sleeved on the rotating shaft 34. After the cam 32 rotates, the pressing rod 2 presses the upper and lower ends of the patch material strip at the same time with the cam 32, and fine-tunes the front and rear position of the patch material strip along the rotation direction.

[0023] A telescopic spring 9 is provided between the connecting rod 6 and the adjusting bolt 7, and the telescopic spring 9 is used in conjunction with the adjusting bolt 7. Both ends of the connecting rod 6 pass through the feed seat 11, and the inner wall of the material receiving trough 1 is provided with a limiting support strip 10. The patch material strip is placed on the upper end of the limiting support strip 10 and conveyed, and the auxiliary conveying operation is performed by the conveying roller 4 and the correcting roller 5. The conveying roller 4 and the correcting roller 5 are both located below the limiting support strip 10. The correcting roller 5 can be adjusted to the left and right sides through the adjusting bolts 7 at both ends of the connecting rod 6 to prevent the patch material strip from shifting inside the material receiving trough 1.

[0024] The device is installed at the feeding port of the SMT machine, and the feeding port of the SMT machine is equipped with a positioning sensor. One end of the SMT tape is manually inserted into the receiving slot 1 and pushed into the SMT machine. As the SMT machine is turned on, the SMT tape is intermittently transported by the traction mechanism inside the SMT machine. When the tape is manually inserted, the tape is prone to deviation. At this time, the adjusting bolts 7 at both ends of the connecting rod 6 can be selected according to the deviation angle to move the deviation correction roller left and right, and the SMT tape is adjusted to the middle of the receiving slot 1.

[0025] When the positioning sensor in the placement machine detects that the patch on the material strip has not reached the robot picking position, the ejection mechanism 3 is started, the telescopic end of the micro cylinder 31 descends, the swing arm pulls the cam downward to rotate, the cam rotates outward, and the pressure roller 2 at the upper end of the material strip squeezes the material strip forward until the patch reaches the robot picking position. When the positioning sensor in the placement machine detects that the patch on the material strip exceeds the robot picking position, the micro cylinder 31 is ejected upward, the swing arm pushes the cam to rotate toward the material receiving trough 1, and the pressure roller 2 at the upper end of the material strip squeezes the material strip backward until the patch reaches the robot picking position, thereby correcting the defect of the spacing caused by the production of patches on the material strip causing the robot picking position deviation.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the utility model content within the protection scope of the utility model.
