Description

Technical Field

[0001] This utility model relates to the field of spring pen tip assembly technology, and in particular to a deformation-resistant press-fit structure and a spring pen tip assembly device having the structure. Background Technology

[0002] A spring-loaded pen tip assembly machine is a mechanical device used to automatically or semi-automatically install spring-loaded pen tips onto pen barrels. This equipment typically includes a feeding system, positioning system, assembly mechanism, detection system, and control system. During production, the equipment efficiently and accurately completes the positioning, assembly, detection, and output of spring-loaded pen tips, ensuring that the assembled pen tips meet quality standards. Spring-loaded pen tip assembly equipment is suitable for the production of various pen products, such as ballpoint pens, gel pens, and fountain pens, significantly improving production efficiency and assembly accuracy while reducing labor costs.

[0003] In practical applications, spring-loaded pen tip assembly equipment has some shortcomings. Specifically, during the press-fitting process, the spring-loaded pen tip may deform due to the applied pressure. This deformation not only affects the pen tip's performance but also negatively impacts its appearance. When the user writes, this deformation may cause uneven or messy handwriting, thus negatively affecting the quality of the final product. Furthermore, deformation of the spring-loaded pen tip may also lead to poor fit between the pen tip and the refill, further affecting the writing experience. Utility Model Content

[0004] The main objective of this invention is to provide an anti-deformation press-fit structure and a spring pen tip assembly device with the same structure, which can effectively solve the problems mentioned in the background art.

The movable rod and the press-fit tube are mounted on the sliding mounting bracket, the pneumatic connector is located at the upper end of the press-fit tube, and the buffer spring is sleeved on the movable rod.

[0007] The lower end of the press-fit tube is equipped with a flexible press-fit component, which enables the assembly of the spring pen tip.

[0008] The flexible press-fit component includes a first assembly cover, a second assembly cover, and a wind resistance cover.

The end face of the side block is provided with a mounting screw hole. The wind resistance cover is provided inside the circular cover, and a connecting pipe is provided at the lower end of the wind resistance cover.

[0009] An inflatable airbag is fitted onto the connecting tube. The inflatable airbag has an inflation port that communicates with the connecting tube. An expansion airbag is provided at the lower end of the inflatable airbag. The expansion airbag drives the spring pen tip to move and realize the pressing operation.

[0010] The first and second assembly covers are designed in a "C" shape when viewed from above. A sealing strip is provided between the first and second assembly covers. The threaded connection part is integrated with the assembly cover it is adapted to. A sealing ring is provided at the connection between the threaded connection part and the press-fitting pipe.

[0011] The wind shield is designed in the shape of a frustum. The wind shield and the connecting pipe are designed as an integral part. The wind shield and the connecting pipe are separated from the first assembly cover and the second assembly cover. A sealing strip is provided at the connection between the wind shield and the connecting pipe.

[0012] The inflatable airbag is connected to the first assembly cover, the second assembly cover, and the connecting pipe by an adhesive. The inflation port is connected to the connecting pipe by a hose. Fresh air flows into the wind resistance cover to inflate the inflatable airbag.

[0013] The inflatable airbag and the expanding airbag are connected by adhesive. The cross-section of the expanding airbag is T-shaped and adapted to the assembly cover. It is connected to the assembly cover by adhesive. The lower end of the expanding airbag is connected to a wear-resistant ring by adhesive.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By using flexible press-fit components, we can ensure that the spring-loaded pen tip is correctly assembled into the designated position during the assembly process. To achieve this, we have specifically adopted an advanced pneumatic system to control the press-fitting operation, automating the entire process and greatly improving operational precision. This automated and precise control method not only significantly improves the efficiency of spring-loaded pen tip assembly but also further enhances the quality and reliability of the assembly.

[0017] Furthermore, the rotary assembly table is compatible with flexible press-fit components, preventing deformation of the spring-loaded pen tip during assembly.

[0028] The wind deflector 9 is designed in a frustum shape and is integrally designed with the connecting pipe 10. The wind deflector 9 and the connecting pipe 10 are separated from the first assembled cover 6 and the second assembled cover 7, and a sealing strip is provided at the connection to ensure airtightness. The inflatable airbag 13 is connected to the first assembled cover 6, the second assembled cover 7 and the connecting pipe 10 by adhesive, and the inflation port 14 is connected to the connecting pipe 10 through a hose. Fresh air flows into the wind deflector 9, causing the inflatable airbag 13 to inflate.

[0029] The inflatable airbag 13 and the expanding airbag 15 are connected together by adhesive. The cross-section of the expanding airbag 15 is designed in a "T" shape and is adapted to the assembly cover. The lower end of the expanding airbag 15 is connected to a wear-resistant ring 16 by adhesive to improve its wear resistance.

[0030] In addition, there is a spring pen tip assembly device that utilizes this anti-deformation press-fit structure. A sliding mounting bracket 1 is connected to a matching sliding device 17, which in turn is connected to a support 18. The support 18 is mounted on a base 20, on which a rotary assembly table 19 is mounted. The flexible press-fit component is aligned with the assembly position on the rotary assembly table 19, thereby enabling the assembly of the spring pen tip. This design effectively improves the efficiency and quality of spring pen tip assembly.

[0031] Installation Process: Install the movable rod 2 and the press-fit tube 5 onto the sliding mounting bracket 1. Fit the buffer spring 3 onto the movable rod 2, ensuring it provides the necessary cushioning. Install the pneumatic connector 4 onto the upper end of the press-fit tube 5.

Install a sealing ring at the connection between the threaded connection 8 and the press-fit tube 5. Ensure the wind resistance cover 9 and the connecting tube 10 are integrated, and install a sealing strip at the connection to ensure a tight seal. Connect the sliding device 17 to the sliding mounting bracket 1. Mount the bracket 18 onto the base 20. Mount the rotary assembly table 19 onto the base 20. Ensure that the flexible press-fit component is aligned with the assembly position on the rotary assembly table 19.

[0032] The procedure is as follows: Turn on the power to the rotary assembly table 19 to start its rotation. Place the spring pen tip in the assembly position on the rotary assembly table 19. Inflate the inflatable airbag 13 through the pneumatic connector 4 to make it expand. The inflatable airbag 15 moves under the action of the inflatable airbag 13, driving the spring pen tip to perform the pressing operation. The flexible pressing component ensures the correct assembly of the spring pen tip through its flexibility. During the pressing process, monitor the assembly quality of the spring pen tip and make adjustments as necessary. After the spring pen tip is assembled, stop the operation of the pneumatic system and the rotary assembly table 19. Remove the assembled spring pen tip from the rotary assembly table 19.
