Description

Assembling system and method of gel ink pen

Technical Field

The invention relates to the field of production of gel-ink pens.

Background

The gel pen comprises a pen sleeve, a tip sleeve, a pen core, a pen holder and a tail plug; the pen holder is of a hollow structure, a tail plug is installed at one end of the pen holder, the pen core is sleeved at the other end of the pen holder and fixed on the pen holder through a tip sleeve, the tip sleeve is conical, the pen sleeve is sleeved on the pen holder, and the pen sleeve is used for protecting the pen core.

The prior gel ink pen assembling equipment, for example, the gel ink pen assembling and forming machine set disclosed in the Chinese patent with the publication number of CN107323128A (published as 20171107), comprises a base station, a pen holder dropping device, a pen holder correcting device, a pen holder installing device, a button dropping device, a tooth dropping device, an inner sleeve dropping device, a pen clip pressing device, a pen sleeve dropping device and a pen sleeve pressing device, the pen holder correction device is positioned between the lower pen holder device and the pen holder loading device, the lower button device, the lower rotary tooth device, the pen sleeve unloading device, the pen sleeve pressing device and the discharge device are sequentially distributed clockwise along the circumferential direction of the large rotary disc, and the lower inner sleeve device, the pen clip unloading device, the pen clip pressing device and the pen sleeve unloading device are sequentially distributed clockwise along the circumferential direction of the small rotary disc.

The existing assembly process of the gel pen comprises the following steps: firstly, feeding and transversely fixing the pen holder, then, feeding and installing the tail plug at one end of the pen holder, then, feeding the refill and pushing the refill into the pen holder, transversely feeding the sharp sleeve to the other end of the pen holder, further pressing the refill into the pen holder, then, screwing the sharp sleeve onto the pen holder, finally, feeding the pen sleeve, and pressing the pen sleeve onto the pen holder to complete the assembly.

However, the above-described gel pen assembly apparatus has the following problems:

1. the pen holder is cylindrical, so that the pen holder is easy to roll when being loaded, the angle is deviated when the pen holder is loaded, and the phenomenon that the pen holder falls out of the jig occurs;

2. the sharp sleeve is conical, so that the feeding is not easy to perform in the transverse placement, the penholder is in the transverse placement during the assembly, and the sharp sleeve needs to be rotated to the penholder in the transverse direction, so that a mechanism capable of conveniently feeding the sharp sleeve from the vertical direction to the transverse direction is needed;

3. because the volume and the mass of the sharp sleeve are small, when the sharp sleeve and the pen holder are initially pressed, the traditional method is to clamp the sharp sleeve to the head end of the pen holder from a sharp sleeve feeding mechanism through a small clamp, and because the sharp sleeve is too small, the clamp is not clamped to the sharp sleeve frequently, so that repeated actions are required for many times, and the assembly efficiency is reduced.

A gel-pen assembly system according to claim 5, wherein the tip-sleeve-tightening device (9) comprises a tip-sleeve-tightening seat (91), a tip-sleeve-tightening slide plate (92), a tip-sleeve-tightening motor (93), a gear assembly (94), a tip-sleeve-tightening spindle (95) and a tip-sleeve-tightening element (96); the upper portion of the sharp sleeve screwing seat (91) is slidably provided with a sharp sleeve screwing sliding plate (92), a sharp sleeve screwing motor (93) is fixedly arranged on the sharp sleeve screwing seat (91), the output end of the sharp sleeve screwing motor (93) is connected with a sharp sleeve screwing rotating shaft (95) through a gear assembly (94), the middle portion of the sharp sleeve screwing rotating shaft (95) is fixed on the sharp sleeve screwing sliding plate (92) through a sharp sleeve screwing rotating shaft mounting seat (951), the right end of the sharp sleeve screwing rotating shaft (95) is connected with a sharp sleeve screwing element (96), and the sharp sleeve screwing element (96) is used for screwing the sharp sleeve on a pen holder.

10. A method of assembling a gel pen, using the assembly system of claim 1; sequentially comprises the following steps:

feeding a pen holder: the penholder enters a penholder positioning block (32) through a penholder feeding box (31), is primarily positioned on the penholder positioning block (32) and then enters a penholder feeding bottom plate (33), a penholder blanking cylinder (35) controls a penholder sliding blanking plate (34) to move, so that the penholder falls through a second penholder blanking hole (341), finally enters a jig (1) through the guidance of a penholder blanking guide plate (36), and is pressed tightly through a pressing device (2);

and (3) feeding and pressing a tail plug: when the tail plug vertically falls to the discharge end of the tail plug feeding guide rail (511), the tail plug feeding control cylinder (5121) drives the tail plug feeding sliding plate (5122) to move, the tail plug feeding sliding plate (5122) drives the first tail plug push rod (5123) and the second tail plug push rod (5124) to move, the first tail plug push rod (5123) presses the tail plug above, the tail plug at the lowest end falls into the tail plug receiving hole (5136), then the tail plug feeding control cylinder (5121) resets, the second tail plug push rod (5124) blocks the tail plug at the lowest end in the tail plug feeding guide rail (511), the tail plug rotating wheel (5131) drives the tail plug feeding block (5133) to rotate, so that the vertical tail plug in the tail plug receiving hole (5136) is turned to be transverse and placed on the penholder, and the tail plug pressing element (523) presses the tail plug in the penholder;

feeding and screwing the tip sleeve: the pen point end of the tip sleeve is arranged below, the pen point end of the tip sleeve vertically falls to the discharge end of a tip sleeve feeding guide rail (811), a tip sleeve feeding control cylinder (8121) drives a tip sleeve feeding sliding plate (8122) to move, the tip sleeve feeding sliding plate (8122) drives a first tip sleeve push rod (8124) and a second tip sleeve push rod (8126) to move, the rear end of the first tip sleeve push rod (8124) is an inclined plane, the rear end of the first tip sleeve push rod (8124) is pressed at the pen point end of the tip sleeve, the first tip sleeve push rod (8124) enables the second tip sleeve to be fixed on the tip sleeve feeding guide rail (811) from bottom to top, the tip sleeve at the lowest end falls into a tip sleeve receiving port (8136), the tip sleeve feeding control cylinder (8121) resets after, and the second tip sleeve push rod (8126) is blocked at the lower part of the tip sleeve at the lowest end; the sharp sleeve rotating wheel (8131) drives a sharp sleeve feeding block (8133) to rotate, so that a vertical sharp sleeve in the sharp sleeve receiving port (8136) is changed into a transverse direction, and the sharp sleeve pressing push plate (822) pushes the sharp sleeve receiving port (8136) to move towards the pen holder, and the sharp sleeve is placed on the pen holder; a sharp sleeve screwing motor (93) drives a sharp sleeve screwing rotating shaft (95) to rotate, and a sharp sleeve screwing element (96) screws the sharp sleeve onto the pen holder;

feeding the pen sleeve: the pen cap vertically falls to the discharge end of a pen cap feeding guide rail (1011), a pen cap feeding control cylinder (10121) drives a pen cap feeding sliding plate (10122) to move, the pen cap feeding sliding plate (10122) drives a first pen cap push rod (10123) and a second pen cap push rod (10124) to move, the first pen cap push rod (10123) presses the pen cap above, the pen cap at the lowest end falls into a pen cap receiving port (10134), then the pen cap feeding control cylinder (10121) resets, the second pen cap push rod (10124) blocks the pen cap at the lowest end in the pen cap feeding guide rail (1011), a pen cap rotating wheel (10131) drives a pen cap feeding block (10133) to rotate, so that the vertical pen cap in the pen cap receiving port (10134) is turned to be horizontal and placed on a pen holder, and the pen cap feeding block (10133) buckles the pen cap on the pen holder.
