Description

Technical Field

[0001] The utility model relates to the technical field of correction tape production, in particular to an external assembly device for a correction tape unwinding wheel and take-up wheel with a belt mouth. Background Art

[0002] The current correction tape includes a lower shell, an upper shell, a nozzle, a pay-out wheel, a belt core, a take-up wheel and a nozzle shell. The assembly steps of the correction tape are as follows: (1) Install the pay-out wheel on the pay-out guide shaft of the lower shell, install the take-up wheel on the take-up guide shaft of the lower shell, and install the nozzle in the nozzle mounting groove of the lower shell, so that the pay-out wheel and the take-up wheel can rotate around the corresponding guide shafts, and the pay-out wheel and the take-up wheel are meshed; (2) Place the belt core on the pay-out wheel, and the core hole of the belt core is connected to the wheel hole of the pay-out wheel, so that the belt core is connected to the pay-out wheel in a transmission manner; (3) The belt core starts to pay-out from the pay-out wheel, and passes through The robot drives the clamp to clamp the core head of the belt, so that the core head of the belt passes around the corresponding belt guide shaft on the lower shell, then passes around the belt mouth, and then passes around the corresponding belt guide shaft. Finally, the core head of the belt is attached to the take-up wheel, and the core head of the belt is wrapped around the take-up wheel for more than half a circle to ensure that the core head of the belt can be firmly attached to the take-up wheel; then the loose belt body is tightened by rotating the take-up wheel; (4) the upper shell and the lower shell are buckled together, and the mouth shell is put on the belt mouth, so that the assembly of the entire correction tape is completed.

[0003] However, when the above-mentioned tape core is being taped, it is necessary to first temporarily attach the tape core head to the tape body guide shaft for pre-positioning, and then use a robot to drive a clamp to clamp the tape core head, so that the tape core head passes around the tape body guide shaft, the belt nozzle, and the tape body guide shaft in sequence, and finally the tape core head can be attached to the take-up wheel. In addition, since the size of the current correction tape is getting smaller and smaller, the distance between the tape release wheel and the take-up wheel is narrow, and the clamp of the robot cannot pass through the gap between the tape release wheel and the take-up wheel, making it difficult for the tape core head to be attached to the take-up wheel. The taping and assembly process is relatively cumbersome and inconvenient, and the assembly efficiency is low. Summary of the invention
