[0025] The following description and the accompanying drawings fully illustrate specific embodiments of the present invention so that those skilled in the art can practice them. Other embodiments may include structural, logical, electrical, process and other changes. The examples represent possible variations only. Unless explicitly required, separate components and functions are optional, and the order of operation may vary. Parts and features of some embodiments may be included in or replace parts and features of other embodiments. The scope of the embodiments of the present invention includes the entire scope of the claims, and all available equivalents of the claims. In this article, these embodiments of the present invention may be represented individually or collectively by the term "invention", which is merely for convenience, and if more than one invention is disclosed in fact, it is not intended to automatically limit the scope of the application to any single invention or inventive concept.

[0026] like Figure 1As shown, the present invention discloses a pen tip loading and unloading tool, comprising: a tool base 1, a pen tube fixing seat 2 assembled on the tool base 1, a pen tip clamping mechanism 3 and a moving mechanism 4; wherein the pen tube fixing seat 2 can be used to disassemble and fix the pen tube 101; the pen tip clamping mechanism 3 is arranged opposite to the position of the pen tube fixing seat 2, so that the pen tip clamping position of the pen tip clamping mechanism 3 is aligned with the center of the front end of the pen tube 101 located in the pen tube fixing seat 2 (that is, the interface position at the bottom of the pen tube 101, the interface position of the connector 103 at the bottom of the pen tube 101, and the position of the pen tip 102 at the bottom of the pen tube 101), and is used for sleeve-fitting and tightening the pen tip 102 during the process of plugging and unplugging the pen tip 102; the moving mechanism 4 is driven by a power mechanism to drive the pen tube fixing seat 2 and the pen tip clamping mechanism 3 to be relatively close to or relatively far away from each other.

[0027] There are currently multiple structures of the direct writing pen 100. The direct writing pen 100 may be composed of a pen tube 101 and a pen tip 102, and the pen tip 102 is assembled at the front end of the pen tube 101. In another structure, the direct writing pen 100 may be composed of a pen tube 101, a connector 103 and the pen tip 102, and the connector 103 is used to provide a connection basis for the pen tube 101 and the pen tip 102. Figure 2 As shown. In another structure, the pen tube 101 may refer to a pen core connected to the pen tip 102. The pen tip mounting and disassembly tool in the embodiment of the present invention can be applied to the structures of the above-mentioned various direct writing pens. In order to avoid excessive elaboration, this article mainly uses the pen tube 101 and the pen tip 102 to constitute the direct writing pen 100 to illustrate the structure and use method of the pen tip mounting and disassembly tool in the embodiment of the present invention.

[0028] The moving mechanism 4 can achieve relative approach or relative distance with the pen tip clamping mechanism 3 by unilaterally controlling the movement of the pen tube fixing seat 2, or can achieve relative approach or relative distance with the pen tip clamping mechanism 3 by unilaterally controlling the movement of the pen tip clamping mechanism 3. In some embodiments, the movement of the pen tube fixing seat 2 and the pen tip clamping mechanism 3 can be controlled separately to achieve relative approach or relative distance between the two. Preferably, the moving mechanism 4 can be driven to move by power such as manpower, air pressure, hydraulic pressure, and electric control.

[0029] The process in which the pen barrel fixing seat 2 and the pen tip clamping mechanism 3 in this embodiment are relatively close to each other can be applied to the process of inserting a new pen tip into the pen barrel; the process in which the pen barrel fixing seat 2 and the pen tip clamping mechanism 3 are relatively far away from each other can be applied to the process of pulling out and disassembling the old pen tip from the pen barrel.

[0030] like Figure 3 The pen tip assembly and disassembly tool in the embodiment shown can be used to assemble and disassemble the pen tip in the following manner:

[0031] The pen tip disassembly process: the pen tube fixing seat 2 and the pen tip clamping mechanism 3 are kept relatively far apart by the moving mechanism 4 to avoid affecting the placement and fixation of the direct writing pen 100 in the pen tube fixing seat 2, and then the pen tube 101 of the direct writing pen 100 is installed and fixed in the pen tube fixing seat 2, so that the pen tip 102 of the direct writing pen 100 is exposed outside the pen tube fixing seat 2 and is opposite to the socket position of the pen tip clamping mechanism 3; thereafter, the pen tube fixing seat 2 and the pen tip clamping mechanism 3 are driven relatively close by the moving mechanism 4 until the pen tip clamping mechanism 3 is socketed on the pen tip 102, and the pen tip clamping mechanism 3 is controlled to fasten the pen tip in its socket position to complete the clamping / locking of the pen tip 102. At this time, the moving mechanism 4 is driven by the power mechanism to make the pen tube fixing seat 2 and the pen tip clamping mechanism 3 relatively far apart, so that the pen tip 102 is pulled out from the pen tube 101, and the disassembly of the old (to be replaced) pen tip 102 is completed.

[0032] Nib assembly process: After the above-mentioned nib disassembly is completed, the old nib is taken out from the nib clamping mechanism 3 and replaced with a new nib, and then the moving mechanism 4 is driven by the power mechanism to make the pen tube fixing seat 2 and the nib clamping mechanism 3 relatively close to each other, so that the nib 102 is connected with the pen tube 101 by interference fit, and the new nib is assembled. The nib assembly process in this embodiment is suitable for completing the nib replacement process in conjunction with the nib disassembly process, and in other embodiments, it is also suitable for assembling a new pen tube with a new nib.

[0033] The tool disclosed in the present invention can effectively make up for the shortcomings of insufficient strength and insufficient experience of the operator in replacing the pen tip. Even a novice with zero experience can quickly complete the replacement process of the pen tip of the direct writing pen by using the tool correctly. Compared with the traditional replacement method, the tool in the present invention has high replacement efficiency and strong reliability.

[0034] like Figure 4In some embodiments, the pen tip loading and unloading tool further includes: a connecting plate 5 stacked on the tool base 1, the connecting plate 5 is hingedly connected to one side of the tool base 1 through a hinge 10, so that the connecting plate 5 and the tool base 1 can be rotated and deformed by the hinge; wherein the tool base 1 is generally arranged to be placed horizontally, at this time, the connecting plate 5 can be lifted by driving the first adjustment component 6, so that the angle between the connecting plate 5 and the tool base 1 changes from 0° to 90°. The pen tube fixing seat 2, the pen tip clamping mechanism 3 and the moving mechanism 4 are assembled on the tool base 1 through the connecting plate 5 (that is, the pen tube fixing seat 2, the pen tip clamping mechanism 3 and the moving mechanism 4 are assembled on the connecting plate 5), wherein the pen tube fixing seat 2, the pen tip clamping mechanism 3 and the moving mechanism 4 are arranged in the same straight line direction and are perpendicular to the hinge between the tool base 1 and the connecting plate 5; the pen tube fixing seat is located on the side away from the hinge position, and follows the connecting plate in a horizontal or inclined state. The first adjustment component 6 may be an adjustment bolt that penetrates the connecting plate 5 and abuts against the surface of the tooling base 1. In some embodiments, one or more buffer pads 13 are further provided on the lower surface of the connecting plate 5 away from the hinge to balance the height difference formed by the hinge between the tooling base 1 and the connecting plate 5; wherein the buffer pad 13 may be made of elastic material, which can be used to alleviate the impact caused by angle adjustment.

[0035] This embodiment can be used to make the air in the pen tube 101 squeeze out of the pen tube 101 under the gravity of the ink during the assembly of the new pen tip, so as to avoid a large amount of air in the pen head of the direct writing pen equipped with the new pen tip, which cannot be discharged and affects the normal ink output of the direct writing pen, and reduce the subsequent debugging time of the direct writing pen after the new pen tip is replaced. Specifically, when replacing the new pen tip, the first adjustment component 6 is used to make the connecting plate 5 form a certain angle relative to the tooling base 1 (horizontal plane), so that the front end of the pen tube is tilted downward at this angle, so that the ink in the pen tube reaches the front end interface of the pen tube, and at this time, the assembly of the new pen tip is quickly completed by the movement of the moving mechanism 4.

[0036] In specific operations, if the adjustment angle is too small, there will be more air between the pen tip and the pen core, which will be difficult to exhaust and the subsequent ink discharge debugging time will be prolonged; if the angle is too large, the liquid metal will be lost too much and wasted during the operation. Therefore, the angle can be controlled to select the time when a drop of metal just flows out slowly from the connector and has not yet dripped due to its own surface tension. At this time, the new pen tip can be quickly assembled by moving the moving mechanism 4.

[0037] In some embodiments, a scale 11 is provided on one side of the connecting plate 5 and the tooling base 1 adjacent to the hinged position, so as to detect the angle formed between the connecting plate 5 and the tooling base 1 .

Preferably, the locking component 304 can be a clamping bolt.

[0039] In some embodiments, a slide rail 7 cooperating with the nib assembly plate 301 is provided on the connecting plate 5 and below the nib assembly plate 301, and the nib assembly plate 301 and the slide rail 7 are driven to move by a power mechanism 12 (handle or electric control component), wherein the slide rail 7 and the cooperating structure of the nib assembly plate 301 and the slide rail 7 constitute the moving mechanism 4. Preferably, the handle can adopt a horizontal push-pull-press toggle clamp.

[0040] like Figure 6 In some embodiments, the connecting plate 5 is provided with a baffle plate 8 for limiting and collecting the ink leaking from the pen tube when the pen tip is installed and removed. In a specific embodiment, the upper surface of the connecting plate 5 has two planes of different heights, wherein the higher plane can be used to assemble the pen tube fixing seat 2, and the lower plane can be used to assemble the slide rail 7 and the pen tip clamping mechanism 3 assembled on the slide rail 7. The baffle plate 8 can be arranged on the lower plane, and cooperates with the edge of the higher plane to form a closed flow limiting structure.

[0041] like Figure 7 In some embodiments, the pen tube fixing seat 2 comprises: a pen tube fixing bracket consisting of an upper bracket 201 and a lower bracket 202; an upper fastening mold 203 and a lower fastening mold 204 arranged in the pen tube fixing bracket for sleeve-fastening the pen tube 101; a lower pressing plate mounting block 205 located on one side of the pen tube fixing bracket, and a lower pressing plate 206 arranged above the pen tube fixing bracket and hinged to the lower pressing plate mounting block 205; the lower pressing plate 206 locks the pen tube fixing bracket through a second adjusting component 207. In some embodiments, the second adjusting component 207 can be an adjusting bolt that passes through the lower pressing plate 206, and the adjusting bolt cooperates with the mounting seat 209 installed below it to complete the fastening of the pen tube fixing bracket. Preferably, the lower pressing plate and the lower pressing plate mounting block are connected by a butterfly spring hinge 208.

[0042] The upper fastening mold 203 and the lower fastening mold 204 can be replaced according to the specific structure of the pen tube of the direct writing pen to meet the requirements of clamping and fixing the direct writing pen. In some embodiments, the upper fastening mold 203 and the lower fastening mold 204 can also correspond to the specific structure of the connector 103 of the direct writing pen.
