The application discloses an automatic rubber strip feeding device to improve production efficiency.

The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

As shown in Figures 1 to 5, the embodiment of the present application provides an automatic tape feeding device, including a frame 8, a tape trolley, a tape detection device 4, a joint assembly 2, a gripping assembly 3 and a guide Component6. The rubber strip trolley can be assembled and separated and arranged on the frame 8. The quantity of the rubber strip trolley is at least one. In this example, two are used, including the first rubber strip trolley 1 and the second rubber strip trolley 9. The rubber strip trolley It includes a trolley bracket 12 and a rubber material roll 16 for winding rubber strips. The rubber material roll 16 is rotated and installed on the trolley bracket 12; the rubber strip detection device 4 is used to detect whether there is a rubber strip on the rubber material roll 16 being used; the joint assembly 2. It includes the bracket 29 and the first clamping component 22, the cutter 23, the rolling component 24, the suction cup component 25 and the second clamping component 28 arranged on the bracket 29. The rubber strip passes through the first clamping component 22 and the suction cup component in sequence 25 and the second clamping assembly 28, the cutter 23 is used to cut the rubber strip between the first clamping assembly 22 and the suction cup assembly 25, and the rolling assembly 24 is used to cut the rubber strip on the suction cup assembly 25. The head is pressed against the tail of another rubber strip; when the rubber strip detection device 4 of the rubber strip detects that there is no rubber strip on the rubber material roll 16 being used, the first clamping component 22 and the second clamping component 28 are clamped The rubber strip, the cutter 23 cuts the rubber strip, and the suction cup assembly 25 sucks the tail of the rubber strip; the clamping assembly 3 is used to clamp the head of the rubber strip on the rubber material roll 16 and move to the suction cup assembly 25 to suck it The tail position of the glue strip; the guide assembly 6 is used to guide the glue strip.

In the rubber strip automatic feeding device provided in the embodiment of the present application, when the rubber strip detection device 4 detects that there is no glue strip on the rubber material roll 16 being used, the first clamping component 22 and the second clamping component 28 clamp the rubber strip , the cutting knife 23 cuts off the rubber strip between the first material clamping assembly 22 and the second material clamping assembly 28, and the suction cup assembly 25 sucks the material tail (the tail of the rubber strip clamped by the first material clamping assembly 22) . Taking the rubber material roll 16 being used as the rubber material roll 16 of the first rubber strip trolley 1 as an example, the clamping assembly 3 clamps the material head of the rubber strip on the rubber material roll 16 of the second rubber strip trolley 9, and the The material head of the rubber strip of the rubber material roll 16 moves to the material tail position of the rubber strip sucked by the suction cup assembly 25, and then the material head of the rubber strip on the suction cup assembly 25 is connected to the material tail of another rubber strip by the rolling assembly 24 Pressing, the rubber material roll 16 of the second rubber strip dolly 9 becomes the rubber material roll 16 in use, and completes the automatic feeding of the rubber strip. Because the glue strip dolly can be assembled and separated and is arranged on the frame 8, therefore, the glue strip dolly that does not have the glue material roll 16 of the glue strip is separated by the frame 8, and the glue strip is reloaded (as changing the glue material roll 16 or reloading To the rubber material roll 16, wind the rubber strip) and then assemble it on the frame 8. Through the above setting, the material tail of the rubber strip is directly connected with the material head of another rubber strip, the whole process shortens the downtime and improves the production efficiency.

When there is no rubber strip on the rubber material roll 16 of the second rubber strip trolley 9, the clamping assembly 3 clamps the head of the rubber strip on the rubber material roll 16 of the first rubber strip trolley 1

At the same time, the swing cylinder 34 swings the material clip to the horizontal position on the right side, the parallel air claw 32 stretches, and the cylinder 33 sends the loosened material clip to the position of the head of the rubber strip on the right. Between 31 and material clamp 37, the parallel air claw 32 shrinks, the material clamp 31 and material clamp 37 clamp the rubber strip material head, the swing cylinder 34 drives the material clamp and the material head to turn 90 degrees counterclockwise, and the module passes through the swing arm 38 drives the material clip and the material head to move upward to the position of the material tail, the rolling assembly 24 stretches out and presses the material head on the material tail, at this time the parallel air claw 32 stretches to loosen the material head, and the rolling assembly 24 rolls upwards under the drive of the cylinder Press, then sew through the sewing assembly 26 to ensure that the material head and the material tail are combined firmly, and then transported forward. After the AGV transports the empty trolley on the left side, it transports the trolley full of rubber strips to the left station. After the rubber strips on the right side are empty, the clamping component 22 and the clamping component 28 clamp the rubber strips at the same time. Live, cutting knife 23 stretches out under the effect of air cylinder and glue strip is cut off, and suction cup assembly 25 sucks material tail.
