DETAILED DESCRIPTION

[0014] The following is combined with Figure 1-3 The present invention will be further described:

[0015] A device for peeling off the bottom paper of the door sealing strip of an automobile automated production line comprises a cutter 3 located between a rubber strip introduction roller 1 and a rubber strip outlet roller 2, a shearing support block 8 being provided below the cutter 3, the cutter 3 cooperating with the shearing support block 8 to cut the sealing strip moved between the two, and in order to ensure the uniformity of the incision depth, the cutter 3 is preferably a flat cutter, the cutter 3 being fixed on a mounting plate 4, the mounting plate 4 being connected to a slider 5, the slider 5 being slidably connected to a guide rail a6, the top of the slider 5 being connected to a cylinder a7, a rotating frame 9 being rotatably connected to a rotating shaft being provided between the cutter 3 and the rubber strip outlet roller 2, the two ends of a return spring 10 being respectively connected to the rotating shaft and the rotating frame 9, and the driven The shaft 11 is rotatably connected to the rotating frame 9. A sensor 18 for detecting the presence of a rubber strip is provided on the side of the driven shaft 11. The sensor 18 is connected to the controller. The sensor 18 is a photoelectric sensor, preferably a Panasonic CX-411 photoelectric sensor. A driving shaft 12 is provided above the driven shaft 11. The driving shaft 12 is connected to the drive motor 13. The drive motor 13 is fixed on the motor base 14. The motor base 14 is slidably connected to the guide rail b15 through the sliding block 16. The top of the motor base 14 is connected to the cylinder b17. The drive motor 13, cylinder a7 and cylinder b17 are all connected to the controller. The controller is a single-chip microcomputer, preferably AT89C51.

[0016] The working process of the device automatically tearing off the bottom paper:

[0017] The rubber strip is transported to the rubber strip inlet roller 1 by the rubber strip transport roller. The rubber strip transport roller is connected to the transport motor, which is connected to the controller. The transport motor drives the rubber strip transport roller to drive the rubber strip to move to the rubber strip inlet roller 1. The rubber strip moves to the rubber strip outlet roller 2 via the rubber strip inlet roller 1. When the photoelectric sensor detects the rubber strip, it sends a signal to the controller. The controller sends an instruction, the transport motor stops running, and the cylinder a7 drives the flat cutter to move down. The stroke of the cylinder a7 is not enough to drive the flat cutter to completely cut the sealing strip, that is, the backing paper of the sealing strip adhesive strip is not cut. The cylinder b17 drives the drive motor 13 and the active shaft 12 to move down through the motor seat 14. The active shaft 12 cooperates with the driven shaft 11 at the bottom to clamp the cut but not broken sealing strip and move it down. The rotating frame 9 rotates downward, the reset spring 10 is compressed, and the sealing strip The compressed reset spring 10 drives the rotating frame 9 to rotate upward, so that the driven shaft 11 continues to be attached to the bottom of the backing paper to ensure that the backing paper is clamped. Driven by the active shaft 12, the torn backing paper is removed synchronously along the feeding direction of the top sealing strip to avoid the accumulation of backing paper.

[0018] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
