[0002] During the production process of RF connectors, one of the steps is to fix the RF connector on a paper tape, and then reel up the paper tape with the RF connector fixed on it to complete the packaging work.

[0003] Currently, manual assistance is required during the paper tape winding process. In addition to replacing the material tray, the manual operation mainly includes first, at the beginning of winding, the paper head part needs to be manually fixed to the winding material tray. Secondly, after a material tray is fully loaded, the paper tape needs to be cut off, and glue is applied on the back of the paper tape to fix the entire reel of paper tape.

[0004] The most complicated operation is how to fix the paper head on the winding material tray at the beginning of winding. Since the width of the paper tape is small, the thickness of the winding material tray receiving cavity is also correspondingly small. The small gap makes manual operation more troublesome, so it takes a lot of time to handle each time the material tray is replaced.

[0005] In view of this, those skilled in the art need to improve the existing structure to overcome the above defects. Utility Model Content

[0006] The main purpose of the present application is to provide an automatic feeding mechanism for the end of a paper tape.

[0008] A further improvement is that a guide roller is rotatably provided at the free end of the feeding arm.

[0009] A further improvement is that the side surface of the free end of the feeding arm has an arc surface.

[0010] A further improvement is that the driving mechanism is a variable frequency drive motor.

[0011] A further improvement is that the positioning mechanism includes a support frame fixedly arranged on the feeding arm, a clamping block slidably arranged on the support frame, and a clamping drive mechanism for driving the clamping block to slide, and there is a gap between the support frame and the feeding arm for the paper tape to pass through.

[0012] A further improvement is that the clamping drive mechanism is a clamping cylinder.

[0013] As a further improvement, the limit detection mechanism includes a mounting plate fixedly arranged on the mounting bracket, a first limit sensor fixedly arranged on the mounting plate, and a second limit sensor.

[0014] As a further improvement, the cutting mechanism includes cutting scissors, a lifting block slidably arranged on the mounting bracket, a lifting drive mechanism driving the lifting block to slide, and a cutting drive mechanism arranged on the lifting block for driving the cutting scissors to move.

[0015] A further improvement is that the lifting drive mechanism is a lifting cylinder.

[0016] A further improvement is that one side arm of the cutting scissors is fixedly connected to the lifting block, the other side arm of the cutting scissors cross-rotates with one side arm, the cutting drive mechanism is a cutting cylinder, the cylinder body of the cutting cylinder is rotatably arranged on the lifting block, and the piston rod of the cutting cylinder is rotatably connected to its other side arm.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] like Figure 1-Figure 3 As shown, an automatic feeding mechanism for the end of a paper tape comprises a mounting bracket 1, a feeding arm 2 rotatably mounted on the mounting bracket 1 at one end, and a driving mechanism for driving the feeding arm 2 to rotate, the other end of the feeding arm 2 is a free end and is provided with a positioning mechanism, a cutting mechanism for cutting off the paper tape is provided below the free end of the feeding arm 2, and a limit detection mechanism 5 for detecting the position of the feeding arm 2 is also provided on the mounting bracket 1.

[0030] In order to reduce the friction of the paper tape during the winding process, a guide roller 4 is rotatably provided at the free end of the feed arm 2. Since the paper tape needs to pass through the gap between the feed arm 2 and the positioning mechanism during the winding process, a guide roller 4 is provided at the end of the feed arm 2, thereby changing the sliding friction into rolling friction, which greatly reduces the friction.

[0031] In order to improve stability, the side surface of the free end of the feeding arm 2 has an arc surface 3. The arc surface 3 is provided so that when the paper head is fed into the winding material tray, the end of the feeding arm 2 can fit the material tray.

[0032] Preferably, in this embodiment, the driving mechanism is a variable frequency drive motor 6. By setting the variable frequency drive motor 6, the rotation angle of the feed arm 2 can be controlled. Therefore, not only the rotation of the feed arm 2 is realized, but also the rotation angle can be set. Therefore, during the winding process, the tension is controlled by changing the rotation angle of the feed arm 2.

[0033] Preferably, in this embodiment, the positioning mechanism includes a support frame 7 fixedly arranged on the feeding arm 2, a clamping block 8 slidably arranged on the support frame 7, and a clamping drive mechanism that drives the clamping block 8 to slide. There is a gap between the support frame 7 and the feeding arm 2 for the paper tape to pass through. Preferably, the clamping drive mechanism is a clamping cylinder 9. In order to realize automatic control of the feeding arm 2, the limit detection mechanism 5 includes a mounting plate fixedly arranged on the mounting bracket 1, a first limit sensor and a second limit sensor fixedly arranged on the mounting plate. In addition, the entire control system also includes a controller. The first limit sensor, the second limit sensor and the variable frequency feeding motor are all electrically connected to the controller. The detection signals of the first limit sensor and the second limit sensor are transmitted to the controller, thereby the controller controls the variable frequency feeding motor to move.

[0034] In this embodiment, preferably, the cutting mechanism includes a cutting scissors 10, a lifting block slidably arranged on the mounting bracket 1, a lifting drive mechanism driving the lifting block to slide, and a cutting drive mechanism arranged on the lifting block for driving the cutting scissors 10 to move. The lifting drive mechanism is a lifting cylinder, one side arm of the cutting scissors 10 is fixedly connected to the lifting block, and the other side arm of the cutting scissors 10 rotates crosswise with its one side arm. The cutting drive mechanism is a cutting cylinder, and the cylinder body of the cutting cylinder is rotatably arranged on the lifting block, and the piston rod of the cutting cylinder is rotatably connected with its other side arm. It should be noted that the specific structure of the lifting drive mechanism and the cutting drive mechanism is not limited to the above structure, and the cutting process is as follows. When the winding is completed, the lifting drive mechanism drives the lifting block to rise, so that the paper tape is located at the shearing edge of the cutting scissors 10, and then the cutting drive mechanism controls the cutting scissors 10 to move to complete the cutting. After the cutting is completed, the lifting block is reset under the action of the lifting drive mechanism.

[0035] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
