Assembly device and method for sealing ring of gel pen holder

Abstract

The invention discloses a device and a method for assembling a sealing ring into a pen clip of a gel pen. The device comprises a tightening device and a clamping and positioning device, wherein the tightening device comprises a tightening unit; the tightening unit is used for fixing the pen clip and fixing the sealing ring inside the pen clip; the compressing and positioning device is connected with the tightening device and is used for applying a downward pressure to the pen clip and fixing the pen clip; the compressing and positioning device applies the downward pressure to the upper end of the pen clip; and the tightening device drives the sealing ring to move upwards inside the pen clip and pushes the pen clip in a sealing ring mounting groove. The sealing ring disclosed by the invention is stable and uniform in mounting; undesirable phenomena of non-in-place of press-in, baroclinity and the like are eliminated, and the productivity is improved.

Description

technical field [0001] The invention relates to the field of automatic assembly of pens, in particular to an assembly device and method for a gel pen clip seal ring. Background technique [0002] In the automatic assembly process of the gel pen holder, it is very important to assemble the sealing ring in the pen holder correctly. If the sealing ring is not pressed in place during assembly, the pressure is skewed, and the pressure is too high, the sealing ring will be damaged. Poor assembly directly affects the progress of the next process, or the high defective rate greatly affects the assembly efficiency and quality of gel pen holder automation equipment. [0003] A kind of pen clip sealing ring assembly device in the prior art, such as figure 1 As shown, when the pen clip 3' of the sealing ring to be pressed reaches the pre-compressed position, the upper positioning device 1' presses down under the action of the power source cylinder 6', so that the pressing seat 11' exer...

[0002] In the automatic assembly process of the gel pen holder, it is very important to assemble the sealing ring in the pen holder correctly. If the sealing ring is not pressed in place during assembly, the pressure is skewed, and the pressure is too high, the sealing ring will be damaged. Poor assembly will directly affect the progress of the next process, or the high defect rate will greatly affect the assembly efficiency and quality of gel pen holder automation equipment

[0003] A kind of pen clip sealing ring assembly device in the prior art, such as figure 1 As shown, when the pen clip 3' of the sealing ring to be pressed reaches the pre-compressed position, the upper positioning device 1' presses down under the action of the power source cylinder 6', so that the pressing seat 11' exerts pressure on the pen clip 3'. Downward pressure; then the lower pressing device 2' pushes the sealing ring upwards driven by the power source cylinder 21', so that the sealing ring reaches the designated position of the sealing ring installation in the cavity of the pen clip 3' holder 22', and the completion is complete. The installation of the sealing ring; however, both the upper positioning device 1' and the lower pressing device 2' use the cylinder as the power source. Due to the compression characteristics of the gas and the fluctuation of the gas source pressure, the pressing speed and strength of the sealing ring are not easy to control. Since the material of the sealing ring is silica gel, it is relatively soft and easy to compress. If there are unstable factors or the speed is too fast when pressing in, it is easy to produce adverse phenomena such as pressure deviation and inclination, which will affect the improvement of production efficiency.
