As shown in fig. 6, the automatic feeding apparatus 10 provided by the present utility model is used for an automatic riveting machine 20, and may be a part of the automatic riveting machine 20.

As shown in fig. 7, the automatic feeding device 10 includes a base plate 11 and a guide shaft 13 mounted above the base plate 11 by two first mounting frames 12, and a slat assembly 14 is slidably connected to the guide shaft 13. Wherein, a first mounting frame 12 is provided with a driving component 15, and two sides of the guide shaft 13 are symmetrically provided with a switch component 16.

Specifically, the first mounting frame 12 includes a fixing base 121 and a first mounting seat 122, the bottom of the fixing base 121 is connected with the bottom plate 11, and the top is connected with the first mounting seat 122. The first mounting seat 122 is provided with a mounting hole, and the guide shaft 13 is connected with the first mounting seat 122 through the mounting hole.

The driving assembly 15 includes a servo motor 151, a coupling 152 connected with the servo motor 151, and a screw pair 153 connected with the coupling 152, wherein the coupling 152 and the screw pair 153 are connected through a bearing housing. The screw pair 153 extends through the first mounting bracket 12 and the guide plate 141 on the slat assembly 14 to below the slat assembly 14. One end of the screw pair 153 is connected to the bearing housing, and the other end is connected to the second mounting bracket 17. The second mounting frame 17 includes a second mounting seat 171 and a supporting seat 172, the bottom of the second mounting seat 171 is connected with the bottom plate 11, the top is connected with the supporting seat 172, and the supporting seat 172 is connected with the screw pair 153.

As shown in fig. 8, the switch assembly 16 includes a first travel detection switch 161, a second travel detection switch 162, a first micro switch 163, and a second micro switch 164. The first travel detection switch 161 and the first micro switch 163 are provided on one side of the guide shaft 13, and the second travel detection switch 162 and the second micro switch 164 are provided on the other side of the guide shaft 13. The first travel detection switch 161 is fixed to the third mounting frame 165, the first micro switch 163 is fixed to the fourth mounting frame 166, the second travel detection switch 162 is fixed to the fifth mounting frame 167, the second micro switch 164 is fixed to the first flow mounting frame 168, and the mounting frames 166 to 168 are fixed to the first mounting frame 12 at corresponding positions.

The automatic feeding device 10 provided by the utility model realizes the feeding control of the slat assembly 14 by utilizing the accurate speed and position control of the servo motor 151 and the screw pair 153, and the working principle is as follows:

during movement of the slat assembly 14, the slat assembly 14 contacts the first microswitch 163, the first microswitch 163 feeds back signals to the control system, the control system outputs information to the servo motor 151, and the servo motor 151 decelerates. The slat assembly 14 continues to move to the first travel detection switch 161, and when the first travel detection switch 161 detects the slat assembly 14, the slat assembly 14 is stopped and a signal is fed back to the control system. The trigger bar assembly 14 is moved back to the initial operating condition, i.e. the first slat aperture in the slat assembly 14 is in the condition to be riveted with the needle. After the first pinhead is riveted, the servo motor 151 controls the screw pair 11 to feed the accurate distance to the second slat hole, and the second slat hole is riveted with the pinhead until the whole slat hole is riveted. After the last needle is riveted, the servo motor 151 continues to feed, and when the end of the slat assembly 14 touches the second micro switch 164, the second micro switch 164 feeds back a signal to the control system to slow down the servo motor 151. When the second travel detection switch 162 detects the slat assembly 14, the end limit position is reached and the slat assembly 14 stops. After the servo motor 151 receives the signal of the control system, the opposite movement enables the slat assembly 14 to move to touch the first micro switch 163, the signal is fed back, the control system outputs information to the servo motor 151, the servo motor 151 decelerates, and the slat assembly 14 continues to move to the limit position of the first travel detection switch 163. The servo motor 151 is moved back to the initial operating position in reverse, while the operator removes the riveted strip from the strip assembly 14 and replaces it with a new, non-riveted strip, with the first strip hole in the new strip to be riveted. Thus, one cycle is completed.

According to the automatic feeding device, manual riveting is replaced by automatic riveting, so that the working efficiency is improved, the cost and the fatigue degree of workers are reduced, the positioning accuracy is high, and the operation is simple.
