Description

Technical Field

[0001] This application relates to the field of acrylic marker manufacturing technology, and more particularly to an acrylic marker ink filling device and method. Background Technology

[0002] Acrylic markers are a type of drawing tool that uses acrylic paint as the core ink component and combines the convenience of marker writing with drawing. Compared to ordinary markers (such as alcohol markers and water-based markers), acrylic markers can be used on a variety of materials (paper, cloth, wood, metal, ceramics, plastics, etc.) due to the characteristics of acrylic paint.

[0003] Current acrylic marker refilling methods typically involve first filling the marker barrel with ink through an opening at the end furthest from the tip, and then sealing the opening with a machine-applied pen tail. High-capacity acrylic markers produced using this method retain a certain amount of air inside the barrel. Furthermore, as the ink volume decreases during use, the air inside the barrel gradually increases due to the siphon effect at the tip. In addition, substandard barrels (with tiny gaps) can allow external air to enter, causing the acrylic paint inside to react with the air, leading to drying, skinning, or oxidation and discoloration, thus negatively impacting the user experience. Summary of the Invention

[0004] This application provides an acrylic marker ink-filling device and method, which can improve the technical problems existing in the related art where the reaction between air and acrylic pigment causes the acrylic pigment to dry, form a skin, or oxidize and discolor.

[0005] In a first aspect, embodiments of this application provide an acrylic marker ink-filling device for filling acrylic markers with ink. The acrylic marker includes a storage section and an ink-filling sealing section, the storage section and the ink-filling sealing section together forming a storage and accommodating space. The ink-filling sealing section has at least one first ink-filling hole communicating with the storage and accommodating space. The acrylic marker ink-filling device includes:

[0006] Installation components;

[0007] A fixing clamping device, disposed on the mounting component, is used to fix the acrylic marker and obtain the weight of the acrylic marker in real time; and

[0008] An ink filling device, disposed on the mounting component, has an acrylic ink receiving space, an ink filling channel communicating with the acrylic ink receiving space, and at least one second ink filling hole communicating with the ink filling channel. The acrylic ink receiving space is used to store acrylic ink. The ink filling device is used to approach and abut against the ink filling seal to fill ink into the receiving space through the acrylic ink receiving space, the ink filling channel, the second ink filling hole, and the first ink filling hole.

[0009] An air extraction device, disposed on the mounting component, has an air extraction channel connected to the ink injection channel. The air extraction device is used to extract air from the storage and accommodating space through the air extraction channel and the ink injection channel.

[0010] The technical solutions described in this application embodiment have at least the following technical effects:

[0011] The acrylic marker refilling device provided in this application provides a storage space for acrylic ink formed by a storage section and an ink-filling sealing section. This allows the acrylic marker to be sealed in the storage space without additional sealing after refilling, improving upon the traditional refilling process where ink is first filled through an opening away from the pen tip, followed by sealing with another device, which can lead to external impurities entering the pen barrel and contaminating the ink. A fixing clamping device ensures the marker does not shift during refilling and precisely controls the amount of ink, reducing the possibility of excessive, insufficient, or misaligned ink affecting the sealing and anti-oxidation effects. The refilling device delivers ink to the storage space through a sealed contact and directional channel (ink-filling channel, second ink-filling hole, and first ink-filling hole), preventing air from entering during the refilling process. An air extraction device removes air from the storage space (including pre-filled air and trace amounts of air that may have entered during refilling) using negative pressure, improving upon the technical problems in related technologies where air reacts with acrylic pigments, causing the pigments to dry, skin, or oxidize and discolor.

[0012] Secondly, embodiments of this application provide an acrylic marker ink-filling method, applied to the acrylic marker ink-filling device described in the first aspect above, the method comprising:

[0013] When the acrylic marker is in a preset position, the ink filling device is controlled to approach and abut against the ink filling seal; wherein, the preset position is the position when the acrylic marker is fixed by the fixing clamping device;

[0014] The weight data is monitored in real time by the fixing and clamping device; wherein the weight data reflects the weight of the acrylic marker;

[0015] First control information and second control information are obtained based on the weight data; the first control information and the second control information are used to control the ink injection device.

[0016] After the second control information is executed, the air extraction device is controlled to connect the air extraction channel with the ink injection channel, extract the air from the storage space, and monitor the pressure data in real time.

[0017] Quality information is obtained based on the pressure data; wherein, the quality information reflects whether the quality of the acrylic marker after ink filling is qualified.

[0018] The technical solutions described in this application embodiment have at least the following technical effects:

[0019] By controlling the ink-filling device to approach and abut against the ink-filling seal, a sealed ink-filling channel is formed, blocking external air from entering the storage space through the ink-filling port. This prevents air from mixing with the ink during the ink-filling process and reduces residual air in the storage space. A fixing clamping device monitors weight data in real time, quantifying the ink-filling amount based on weight changes, thus solving the problem of relying on experience to judge ink volume in traditional ink-filling processes. Based on the weight data, first and second control information are obtained, converting the weight monitoring data into ink-filling actions executed by the control device, replacing manual operation and avoiding human error. After the second control information is executed, the air extraction device connects the air extraction channel to the ink-filling channel, extracting air from the storage space and monitoring pressure data in real time. This removes residual air from the storage space after ink-filling, reducing the air content and thus lowering the possibility of acrylic pigment drying, skinning, oxidation, and discoloration due to contact with air. Simultaneously, the pressure data prevents excessive air extraction from creating excessive negative pressure in the storage space, preventing moisture evaporation from the acrylic pigment. Finally, quality information is obtained based on pressure data, and the airtightness of the pen holder is detected by the pressure change pattern in the storage space. This reduces the possibility that the pigment will deteriorate (dry, form a skin, oxidize and discolor) due to external air entering the pen holder through gaps during use, thus affecting the user experience.

[0036] Acrylic markers are a type of drawing tool that uses acrylic paint as the core ink component and combines the convenience of marker writing with drawing. Compared to ordinary markers (such as alcohol markers and water-based markers), acrylic markers can be used on a variety of materials (paper, cloth, wood, metal, ceramics, plastics, etc.) due to the characteristics of acrylic paint.

[0037] Current acrylic marker refilling methods typically involve first filling the cartridge with ink through an opening at the end furthest from the tip, and then sealing the opening with a pen tail attached using machinery. High-capacity acrylic markers produced using this method retain a certain amount of air inside the cartridge (air in the gap between the ink and the cartridge). Furthermore, as the ink volume decreases during use, the air inside the cartridge gradually increases due to the siphon effect of the pen tip. In addition, substandard cartridges (with tiny gaps) can allow external air to enter, causing the acrylic paint inside to react with the air, leading to drying, skinning, or oxidation and discoloration, thus affecting the user experience.

[0038] Based on this, in order to improve the technical problems in the related technology where the reaction between air and acrylic pigment causes the acrylic pigment to dry, form a skin, or oxidize and discolor, the embodiments of this application provide the following solutions.

[0039] Please see Figure 1 This application provides an acrylic marker ink filling device 100 for filling acrylic markers 200 with ink. The acrylic marker 200 includes a storage section 60 and an ink filling sealing section 50. The storage section 60 and the ink filling sealing section 50 together form a storage and receiving space 61. The ink filling sealing section 50 has at least one first ink filling hole 511 communicating with the storage and receiving space 61. The acrylic marker ink filling device 100 includes a mounting member 10, a fixing clamping device 20, an ink filling device 30, and an air extraction device 40, wherein:

[0040] The fixing clamping device 20 is disposed on the mounting part 10 and is used to fix the acrylic marker 200 and obtain the weight of the acrylic marker 200 in real time.

[0041] The ink filling device 30 is disposed on the mounting member 10 and has an propylene receiving space, an ink filling channel 321 communicating with the propylene receiving space, and at least one second ink filling hole 322 communicating with the ink filling channel 321. The propylene receiving space is used to store propylene ink. The ink filling device 30 is used to approach and abut against the ink filling sealing part 50 to inject ink into the storage receiving space 61 through the propylene receiving space, the ink filling channel 321, the second ink filling hole 322, and the first ink filling hole 511.

[0042] An air extraction device 40 is mounted on the mounting component 10 and has an air extraction channel that is connected to the ink injection channel 321. The air extraction device 40 is used to extract air from the storage and accommodating space 61 through the air extraction channel and the ink injection channel 321.

[0043] It is understood that the storage section 60 is a tubular structure that can together with the ink filling and sealing section 50 form a storage and accommodating space 61 to store acrylic pigments. For example, the storage section 60 can be a plastic tube, an aluminum tube, etc., but is not limited to these.

[0044] The ink filling sealing part 50 is a device that combines the functions of an ink filling interface and a sealed storage and accommodating space 61. For example, the ink filling sealing part 50 may include a cover and a solenoid valve. The cover is disposed on the storage part 60 and has a first ink filling hole 511. The solenoid valve is disposed on the cover and is used to block or open the first ink filling hole 511, etc., but is not limited thereto.

[0045] Mounting component 10 is a device used to fix the relative positions of the fixing clamping device 20, the ink injection device 30 and the air extraction device 40, and to provide stable support for their coordinated operation. For example, mounting component 10 can be an aluminum mounting bracket, a copper mounting bracket, etc., but is not limited to these.

[0046] The fixing and clamping device 20 is a device that can accurately fix the marker pen and monitor the ink volume in real time. For example, the fixing and clamping device 20 may include a weighing device (electronic platform scale, belt scale, etc.) and a clamping device (pneumatic clamping device, electric clamping device, etc.). The weighing device can be set on the mounting part 10, and the clamping device can be set on the mounting part 10 for clamping the acrylic marker 200 and moving the acrylic marker 200 onto the weighing device.

[0047] The ink filling device 30 is a device that can deliver acrylic ink to the storage and receiving space 61 through a sealed contact and directional channel, while preventing air from entering during ink filling. For example, the ink filling device 30 may include an acrylic storage tank (aluminum storage tank, plastic storage tank, etc.), a drive cylinder (straight rod cylinder, double-acting cylinder, etc.), and an ink filling tube (aluminum tube, plastic tube, etc.). The acrylic storage tank can be mounted on the mounting member 10 and has an acrylic receiving space. The drive cylinder can be mounted on the mounting member 10 and located above the fixing clamping device 20. The ink filling tube can be mounted on the power output end of the drive cylinder and has an ink filling channel 321 and a second ink filling hole 322. The acrylic receiving space can be connected to the ink filling channel 321 through a sufficiently long flexible pipe (the flexible pipe will not be stretched when the drive cylinder drives the ink filling tube to move). The drive cylinder is used to drive the ink filling tube to approach and contact the ink filling sealing part 50 so that the ink filling channel 321 is connected to the storage and receiving space 61, etc., but not limited to this.

[0048] The air extraction device 40 is a device that extracts air from the storage and containment space 61 by communicating with the ink injection channel 321. For example, the air extraction device 40 can be a rotary vane vacuum pump, a slide valve vacuum pump, etc., but is not limited to these.

[0049] As can be seen from the above, the acrylic marker ink-filling device 100 provided in this application embodiment forms a storage and containment space 61 for storing acrylic ink through the storage section 60 and the ink-filling sealing section 50. This allows the acrylic marker 200 to be sealed in the storage and containment space 61 without additional sealing procedures after ink filling. This improves upon the problem in traditional ink-filling processes where ink is first filled through an opening at the end of the pen barrel furthest from the tip, and then sealed by another device, which may lead to external impurities entering the pen barrel and contaminating the ink. The fixing and clamping device 20 ensures that the marker does not shift during ink filling and precisely controls the amount of ink filled, reducing the possibility that excessive, insufficient, or misaligned ink may affect the sealing and anti-oxidation effects. The ink-filling device 30 delivers ink to the storage and containment space 61 through a sealed contact and directional channel (ink-filling channel 321, second ink-filling hole 322, and first ink-filling hole 511), preventing air from entering during ink filling. The air in the storage space 61 is removed by the air extraction device 40 using negative pressure extraction (including the original air in the storage space 61 before ink filling, and trace amounts of air that may be mixed in during the ink filling process). This improves the technical problem in related technologies where air reacts with acrylic pigments, causing the acrylic pigments to dry, form skins, or oxidize and discolor.

[0050] In some embodiments, please refer to the following: Figure 2 and Figure 3 The ink-filling sealing part 50 includes a fixing member 51, a movable member 52, and an elastic member 53.

[0051] The fixing member 51 is disposed on the storage section 60. The fixing member 51 has a first ink injection hole 511 and a movable receiving space 512. The movable receiving space 512 has a first position 513 and a second position 514.

[0052] The movable part 52 is located within the movable accommodating space 512 and is movably mounted on the fixed part 51. The movable part 52 has a third ink injection hole 521 corresponding to the first ink injection hole 511. An elastic movable space 522 is formed between the fixed part 51 and the movable part 52.

[0053] The elastic element 53 is located within the elastic movable space 522, and its two ends are connected to the fixed element 51 and the movable element 52, respectively.

[0054] The fixing member 51 and the storage part 60 together form a storage and accommodating space 61. The elastic member 53 is used to drive the movable member 52 to approach the first position 513. When the movable member 52 is in the first position 513, the first ink injection hole 511 and the third ink injection hole 521 are not connected. The ink injection device 30 is used to approach and abut the movable member 52 and drive the movable member 52 to approach the second position 514. When the movable member 52 is in the second position 514, the first ink injection hole 511 and the third ink injection hole 521 are connected. The ink injection device 30 injects ink into the storage and accommodating space 61 through the ink injection channel 321, the first ink injection hole 511, the second ink injection hole 322 and the third ink injection hole 521.

[0055] It is understood that the fixing member 51 serves as the fixing base for the ink filling sealing part 50, connects the storage part 60 to form a closed storage and accommodating space 61, and provides a first ink filling hole 511 and a movable accommodating space 512. For example, the material of the fixing member 51 can be polyethylene, polypropylene, etc., but is not limited to these.

[0056] The movable part 52 achieves the opening and closing of the first ink injection hole 511 and the third ink injection hole 521 by axial movement. When no ink is being injected, the channel is blocked to prevent air from entering, and when ink is being injected, the channel is opened to allow ink to be injected. For example, the material of the movable part 52 can be polyethylene, polypropylene, etc., but is not limited to these.

[0057] The elastic element 53 drives the movable element 52 to always remain in the first position 513 (the sealed state when not filling ink) through elastic deformation, ensuring that the first ink filling hole 511 and the third ink filling hole 521 are always disconnected during the ink filling process, thus structurally preventing air from entering the storage and accommodating space 61. For example, the elastic element 53 can be a cylindrical helical compression spring, a disc spring, etc., but is not limited to these.

[0058] With this configuration, in the non-inking state (daily storage, transportation), the elastic element 53 drives the movable element 52 to the first position 513. The third ink filling hole 521 of the movable element 52 is completely misaligned with the first ink filling hole 511 of the fixed element 51. The storage space 61 is blocked from the outside through the first ink filling hole 511, preventing external air from entering the storage space 61 through the third ink filling hole 521 and the first ink filling hole 511. In the ink filling state, the ink filling element 32 of the ink filling device approaches and abuts against the abutting end of the movable element 52 and applies an axial thrust. The axial thrust overcomes the elastic force of the elastic element 53 and drives the movable element 52 to move axially along the movable space 512 to the second position 514. The elastic element 53 is compressed, and the third ink filling hole 521 and the first ink filling hole... When 511 is fully aligned, the second ink injection hole 322 of the ink injection component 32 is connected to the third ink injection hole 521. The ink injection device injects ink into the storage and receiving space 61 through the ink injection channel 321, the second ink injection hole 322, the third ink injection hole 521 and the first ink injection hole 511, achieving leak-free ink injection and preventing external impurities from entering the storage and receiving space 61 during the ink injection process. After ink injection is completed, the ink injection component 32 moves away from the movable component 52, and the elastic force of the elastic component 53 is released, pushing the movable component 52 to move in the opposite direction along the movable receiving space 512 to the first position 513. The first ink injection hole 511 and the third ink injection hole 521 are misaligned, and the storage and receiving space 61 returns to a sealed state, preventing external air from entering after ink injection and reducing the risk of air backflow when the ink injection device is pulled out.

[0059] In some embodiments, please refer to the following: Figures 1 to 3 The ink injection device 30 includes a storage injection mechanism 31, an ink injection component 32, an ink injection pipe 33, an ink injection partition 34, and an ink injection drive component 35.

[0060] The storage injection mechanism 31 is mounted on the mounting component 10 and has a propylene receiving space.

[0061] The ink filling component 32 has an ink filling channel 321. A second ink filling hole 322 is provided on the side of the ink filling component 32 away from the storage and injection mechanism 31. The end of the ink filling component 32 away from the storage and injection mechanism 31 is recessed into the ink filling channel 321 to form a guide portion 323. A guide space 324 communicating with the ink filling channel 321 is formed between the periphery of the guide portion 323 and the inner wall of the ink filling component 32. The second ink filling hole 322 is connected to the guide space 324.

[0062] The ink injection pipe 33 has a connecting channel. Both ends of the ink injection pipe 33 are connected to the storage injection mechanism 31 and the ink injection component 32, respectively. The connecting channel is also connected to the propylene containment space and the ink injection channel 321.

[0063] Ink filling partition 34 is disposed on ink filling component 32 and is used to connect or disconnect the connecting channel and ink filling channel 321.

[0064] The ink injection drive 35 is disposed on the mounting part 10, and the ink injection part 32 is disposed on the power output end of the ink injection drive 35. The ink injection drive 35 is used to drive the ink injection part 32 to approach and abut against the ink injection sealing part 50, so that the ink injection channel 321 is connected to the storage and accommodating space 61 through the flow guide space 324, the second ink injection hole 322 and the first ink injection hole 511.

[0065] It is understood that the storage and injection mechanism 31, as a storage and initial delivery device for acrylic ink, provides a continuous and stable ink supply for the ink injection process, while preventing oxidation and deterioration of the ink due to prolonged contact with air. For example, the storage and injection mechanism 31 may include a sealed storage tank (aluminum storage tank, plastic storage tank, etc.) and a pressure balancing valve. The sealed storage tank may be installed on the mounting component 10 and has an acrylic ink containing space. The pressure balancing valve may be installed on the sealed storage tank to supplement air during ink injection (to prevent negative pressure in the acrylic ink containing space from preventing ink from flowing out).

[0066] The ink-filling component 32 is a tubular structure that achieves uniform ink delivery through the ink-filling channel 321, the guide section 323, and the flow space, while simultaneously forming a sealed contact with the ink-filling sealing section 50. The guide section 323 can be conical, hemispherical, etc., with its apex facing the inside of the ink-filling channel 321, and its periphery forming an annular flow space 324 with the inner wall of the ink-filling component 32, but is not limited to this. For example, the ink-filling component 32 can be an aluminum tube, a plastic tube, etc., but is not limited to this.

[0067] Ink filling conduit 33 connects the ink storage and injection mechanism 31 and the ink filling component 32, forming a closed ink transport path to prevent ink from coming into contact with air or leaking during transport. For example, ink filling conduit 33 can be a polyurethane steel wire tube, Teflon flexible hose, etc., but is not limited to these.

[0068] The ink injection isolation component 34 controls the opening and closing of the connection channel and the ink injection channel 321, achieving a timing coordination of isolation during air extraction and connection during ink injection. This prevents air from entering the ink injection channel 321 from the storage and injection mechanism 31 during air extraction. The ink injection isolation component 34 can also be installed on the storage and injection mechanism 31. For example, the ink injection isolation component 34 can be a direct-acting solenoid valve, a pilot-operated solenoid valve, etc., but is not limited to these.

[0069] The ink injection drive 35 drives the ink injection component 32 to move axially, achieving precise contact with the ink injection sealing part 50 (with controllable force) while ensuring the alignment accuracy of the ink injection hole. For example, the ink injection drive 35 can be a drive cylinder, a drive motor, etc., but is not limited to these.

[0070] With this configuration, the ink injection component 32 is driven by the ink injection drive 35 to move towards the ink injection sealing part 50 until the ink injection component 32 is in contact with the moving part 52 and the contact pressure reaches a preset value. During the ink injection stage, the ink injection isolation component 34 connects the ink injection channel 321 and the connecting channel. Under the action of gravity and / or pressure, the ink in the storage injection mechanism 31 is injected into the storage and receiving space 61 through the connecting channel, the ink injection channel 321, the guide space 324, the second ink injection hole 322, the third ink injection hole 521, and the first ink injection hole 511. The weight change is monitored in real time by the fixing clamping device 20. When the weight reaches the target ink injection amount, the ink injection isolation component 34 isolates the ink injection channel 321 from the connecting channel, stopping the ink injection. After the air extraction process is completed, the ink injection drive 35 drives the ink injection component 32 to move in the opposite direction and disengage from the ink injection sealing part 50.

[0071] In some embodiments, please refer to Figure 1 The air extraction device 40 includes an air extraction conveying component 41, an air extraction isolation component 42, a pressure acquisition component 43, and an air extraction driving component 44.

[0072] The air extraction and conveying component 41 has an air extraction channel. One end of the air extraction and conveying component 41 is connected to the ink injection component 32, and the air extraction channel is connected to the ink injection channel 321.

[0073] The air extraction isolation component 42 is disposed on the air extraction conveyor 41 at one end near the ink injection component 32, and is used to isolate or connect the air extraction channel and the ink injection channel 321.

[0074] The pressure acquisition element 43 is located inside the ink filling channel 321 and is installed on the ink filling element 32. It is used to monitor the pressure in the storage space 61 in real time when the ink filling channel 321 is connected to the storage space 61 and the connecting channel is isolated from the ink filling channel 321.

[0075] The air extraction drive 44 is mounted on the mounting part 10 and connected to the other end of the air extraction conveyor 41. It is used to extract air from the storage and accommodating space 61 through the air extraction channel, ink injection channel 321, flow guide space 324, second ink injection hole 322 and first ink injection hole 511.

[0076] It is understood that the air extraction and delivery component 41 connects the ink injection component 32 and the air extraction drive component 44, forming a closed air extraction path to ensure that the air in the storage and containment space 61 can be directionally and leak-free discharged. For example, the air extraction and delivery component 41 can be a rigid delivery pipe, a rubber delivery hose, etc., but is not limited to these.

[0077] The air extraction isolation component 42 controls the opening and closing of the air extraction channel and the ink injection channel 321, achieving a timing coordination between connection during air extraction, ink injection, and isolation during idle periods, thus preventing ink from flowing into the air extraction system during ink injection. For example, the air extraction isolation component 42 can be a direct-acting solenoid valve, a pilot-operated solenoid valve, etc., but is not limited to these.

[0078] The pressure acquisition element 43 monitors the pressure changes within the storage space 61 in real time through the ink injection channel 321, providing precise control data for the suction drive element 44. For example, the pressure acquisition element 43 can be a miniature negative pressure sensor, a composite pressure sensor, etc., but is not limited to these.

[0079] The suction drive 44 provides continuous and adjustable suction power to extract air from the storage compartment 61 through the suction channel. For example, the suction drive 44 can be an oil-free miniature vacuum pump, a reciprocating vacuum pump, etc., but is not limited to these.

[0080] With this configuration, during the air extraction phase, the ink injection partition 34 connects the ink injection channel 321 to the connecting channel. The air extraction drive 44 expels air from the storage space 61 through the first ink injection hole 511, the third ink injection hole 521, the second ink injection hole 322, the guide space 324, the ink injection channel 321, and the air extraction channel. This reduces the amount of residual air in the storage space 61, thereby extending the drying and skinning time, reducing the oxidation and discoloration rate, and automatically starting, stopping, or adjusting the air extraction power based on the pressure data collected in real time by the pressure acquisition device 43. The air extraction partition 42 connects the air extraction channel to the ink injection channel 321, rather than having a separate air extraction port. By reusing the existing ink injection channel 321, equipment redundancy is reduced, and channel sealing is ensured.

[0081] By pre-extracting air from the storage space 61, a near-saturated state (without a distinct "air cavity") is achieved where the ink is fully filled with a small amount of residual air. When the siphon effect kicks in and the ink flows towards the tip, the change within the storage space 61 is that ink flows out of the storage space 61, and the gap between the ink and the storage section 60 increases slightly. However, because the air content in the gap is small, this gap is not immediately filled with air. Instead, a "low negative pressure" (a very low negative pressure, only slightly lower than the external atmospheric pressure) is first formed. Since external air needs to overcome the resistance of the tip to enter the storage space 61 through the tip, this pressure is significantly reduced. (Due to the resistance of the pen core structure and the viscosity resistance of the pigment itself), in the "low negative pressure" stage, the difference between the external atmospheric pressure and the negative pressure inside the storage space 61 is very small. External air can only slowly and in small amounts seep in. Before the pressure inside the storage space 61 reaches the external atmospheric pressure, the infiltration rate of external air is less than the infiltration rate of external air when the pressure inside the storage space 61 is equal to the external atmospheric pressure. Therefore, by pre-extracting air from the storage space 61 to form a low negative pressure, the time for external air to enter the storage space 61 can be delayed, thereby improving the technical problem in the related technology where air reacts with acrylic pigment, causing the acrylic pigment to dry, form a skin, or oxidize and discolor.

[0082] For example, the ink filling process and the air extraction process can be performed alternately. For instance, multiple weight values ​​and multiple air pressure values ​​can be preset according to the volume of the storage and holding space 61. During the ink filling process, when the weight monitored by the fixing clamping device 20 reaches a certain weight value, the ink filling device 30 is controlled to pause the ink filling process. Then, the air extraction device 40 performs an air extraction process to extract some air from the storage and holding space 61 and monitors the air pressure in the storage and holding space 61 in real time. When the monitored air pressure in the storage and holding space 61 reaches a certain air pressure value, the air extraction device 40 is controlled to pause the air extraction process, and the ink filling device 30 is controlled to continue the ink filling process. This process continues until both the monitored weight and the monitored air pressure in the storage and holding space 61 reach the corresponding preset standard values. This setup, compared to achieving the pre-set standard values ​​for both the monitored weight and the air pressure within the storage space 61 through only one ink filling process and one air extraction process, reduces the impact of the air pressure within the storage space 61 on the ink filling process (the air pressure within the storage space 61 increases as the amount of ink in the storage space 61 increases), making the ink filling process more stable.

[0083] In some embodiments, please refer to Figure 1 The fixed clamping device 20 includes a weighing mechanism 21 and a clamping mechanism 22.

[0084] Weighing mechanism 21 is mounted on mounting component 10 and is used to obtain the weight of acrylic marker 200.

[0085] The clamping mechanism 22 is provided on the mounting part 10 and is used to fix the acrylic marker 200 to the weighing mechanism 21 and restrict the movement of the acrylic marker 200 in the horizontal direction.

[0086] It is understandable that the weighing mechanism 21 collects the weight change of the acrylic marker 200 before and after ink filling in real time, providing data support for the start and stop of the ink filling device 30. For example, the weighing mechanism 21 can be an automatic checkweigher, a weighing sensor, etc., but is not limited to these.

[0087] The clamping mechanism 22 is used to fix the acrylic marker 200 onto the weighing mechanism 21, and to position the acrylic marker 200 directly below the ink filling part 32. It also restricts the horizontal movement and rotation of the acrylic marker 200, ensuring precise alignment of the first ink filling hole 511 and the second ink filling hole 322 during ink filling, while preventing seal failure or ink leakage caused by the pen body tilting when the ink filling part 32 is in contact with the marker. For example, the clamping mechanism 22 can be a symmetrical clamp, a parallel clamp, etc., but is not limited to these.

[0088] With this setup, acrylic markers 200 (tip down, ink filling seal 50 up) are conveyed to the side of the clamping mechanism 22 or onto the weighing mechanism 21 via manual operation, a conveyor belt, or a vibrating feeding device. The clamping mechanism 22 then holds the acrylic markers 200 located on the side and moves them onto the weighing mechanism 21, or fixes the acrylic markers 200 on the weighing mechanism 21. After the refilling and degassing processes are completed, the clamping mechanism 22 can move the acrylic markers 200 from the weighing mechanism 21 onto the side conveyor belt, release the acrylic markers 200 for manual transfer, or move substandard acrylic markers 200 to a pre-designated recycling area.

[0089] Please see Figure 4 This application also provides an acrylic marker ink filling method, applied to the acrylic marker ink filling device 100 of any of the above claims. The acrylic marker ink filling method includes:

[0090] When the acrylic marker is in the preset position, the ink filling device is controlled to approach and contact the ink filling seal; wherein, the preset position is the position when the acrylic marker is fixed by the fixing clamping device.

[0091] The weight data is monitored in real time through a fixed clamping device; the weight data reflects the weight of the acrylic marker.

[0092] First control information and second control information are obtained based on weight data; the first control information and second control information are used to control the ink injection device.

[0093] After the second control information is executed, the control air extraction device connects the air extraction channel to the ink injection channel, extracts air from the storage space, and monitors the pressure data in real time.

[0094] Quality information is obtained based on pressure data; this quality information reflects whether the acrylic markers are up to standard after ink filling.

[0095] As described above, the acrylic marker ink filling method provided in this application embodiment controls the ink filling device to approach and abut against the ink filling sealing part to form a sealed ink filling channel, blocking external air from entering the storage space through the ink filling port, avoiding air mixing with the ink during the ink filling process, and reducing residual air in the storage space. Furthermore, the fixed clamping device monitors weight data in real time, quantifying the ink filling amount based on weight changes, solving the problem of relying on experience to judge the ink filling amount in traditional ink filling processes. Based on the weight data, first and second control information are obtained, converting the weight monitoring data into ink filling actions executed by the control device, replacing manual operation and avoiding human error. After the second control information is executed, the air extraction device connects the air extraction channel to the ink filling channel, extracting air from the storage space and monitoring pressure data in real time to remove residual air from the storage space after ink filling, reducing the air content in the storage space, thereby reducing the possibility of acrylic pigment drying, skinning, oxidation, and discoloration due to contact with air. Simultaneously, based on the pressure data, excessive air extraction is avoided to prevent the formation of a large negative pressure in the storage space, preventing the evaporation of moisture from the acrylic pigment. Finally, quality information is obtained based on pressure data, and the airtightness of the pen holder is detected by the pressure change pattern in the storage space. This reduces the possibility that the pigment will deteriorate (dry, form a skin, oxidize and discolor) due to external air entering the pen holder through gaps during use, thus affecting the user experience.

[0096] To better understand the acrylic marker ink filling method provided in the embodiments of this application, the specific implementation process of the acrylic marker ink filling method provided in the embodiments of this application will be described by way of example below.

[0097] Figure 4 A schematic flowchart of an acrylic marker ink-filling method provided in an embodiment of this application is shown. The acrylic marker ink-filling method includes:

[0098] S100, when the acrylic marker is in a preset position, controls the ink filling device to approach and abut against the ink filling seal; wherein, the preset position is the position when the acrylic marker is fixed by the fixing clamping device.

[0099] It is understandable that determining whether an acrylic marker is in a preset position can be achieved by determining that the acrylic marker is in a preset position when the weight data transmitted in real time by the fixing and clamping device is stable and the value of the weight data is equal to the preset marker weight, or by using an image acquisition device (digital camera, infrared camera, etc.) set on the mounting component, but is not limited to these methods. Controlling the ink filling device to approach and abut against the ink filling seal can be achieved by controlling the ink filling drive to drive the ink filling component to approach and abut against the ink filling seal at a preset speed, or by using a distance sensor set on the ink filling component to monitor the distance between the ink filling component and the ink filling seal in real time, and controlling the movement speed of the ink filling drive based on the distance (controlling the ink filling drive to move the ink filling component at a first preset speed when the distance between the ink filling component and the ink filling seal is greater than a preset distance, controlling the ink filling drive to move the ink filling component at a second preset speed when the distance between the ink filling component and the ink filling seal is less than or equal to the preset distance, and the first preset speed is greater than the second preset speed), but is not limited to these methods.

[0100] The S200 monitors weight data in real time through a fixed clamping device; the weight data reflects the weight of the acrylic marker.

[0101] It is understandable that by using a fixed clamping device to monitor weight data in real time and capturing changes in the pen's weight, data support can be provided for precise control of ink volume and prevention of ink waste or insufficient ink, while indirectly ensuring the sealing and stability of the ink filling process.

[0102] S300, first control information and second control information are obtained based on weight data; the first control information and second control information are used to control the ink injection device.

[0103] It is understandable that the first control information based on weight data can be obtained by using a preset first weight threshold (the total weight of the acrylic marker when the ink filling device and the ink filling seal are fully in contact, including the combined weight of the marker body and the ink filling device after contact) as a benchmark. When the weight data reaches the first preset weight (indicating that the preparatory work (positioning and sealing) before ink filling is completed), the first control information is obtained to control the ink filling device to stop approaching the ink filling seal (to avoid excessive pressure that could damage the sealing structure) and to control the ink filling device to open the ink filling channel and inject ink into the marker's storage space. The second control information based on weight data can be obtained by using the weight of the injected ink from the real-time monitored weight data. When the ink weight reaches a preset ink weight, the second control information is obtained to control the ink filling device to stop injecting ink into the storage space. Based on the weight data, the first and second control information can be obtained. Through the dynamic changes in the weight data, the ink injection device can be automatically triggered to start ink injection, stop ink injection, and isolate the channel (control the ink injection partition to isolate or connect the connection channel and the ink injection channel). This realizes the automatic control of the ink injection system, avoids human operation errors, and ensures accurate ink injection volume and a sealed ink injection environment.

[0104] In one possible implementation, please refer to Figure 5 S300, based on weight data, obtains first control information and second control information, including:

[0105] S310, Obtain the initial weight; where the initial weight is the weight data of the acrylic marker when it is in the preset position.

[0106] It is understandable that the initial weight can be obtained by taking the acrylic marker in the preset position before it is filled with ink, and by confirming the real-time weight data monitored by the clamping device as the initial weight, or by receiving data transmitted by the user, etc., but it is not limited to these methods. Obtaining the initial weight provides a basis for subsequent steps.

[0107] S320, when the weight data reaches the first preset weight, first control information is generated; wherein, the first control information is used to control the ink filling device to stop moving and to fill the storage space with ink.

[0108] It is understood that the first preset weight is a pre-set total weight reflecting the condition where "the ink filling device and the ink filling seal are completely in contact, and the acrylic marker is stably fixed." This weight can be set by the user, or it can be obtained by searching a preset database for the model of the acrylic marker that needs ink filling, but it is not limited to these methods. When the weight data reaches the first preset weight, first control information is generated to control the ink filling device to stop moving and to fill the storage space with ink, reducing the possibility of damage to the ink filling seal (such as cracking of the fixing or moving parts) or deformation of the storage part (especially the storage part made of plastic) due to excessive compression.

[0109] The S330 determines the ink weight by subtracting the initial weight from the real-time monitored weight data.

[0110] It is understandable that calculating and confirming the ink weight in real time provides a basis for subsequent judgment on whether the ink volume meets the standard.

[0111] For example, assuming the initial weight is 50g and the weight data detected at a certain moment is 55g, then the ink weight = 55 - 50 = 5g.

[0112] S340, when the ink weight reaches the second preset weight, second control information is generated; wherein, the second control information is used to control the ink filling device to stop filling the storage space with ink and to isolate the ink filling channel and the acrylic storage space from each other.

[0113] It is understandable that the second preset weight is based on the designed capacity of the acrylic marker (e.g., 10ml, 20ml) and the density of acrylic pigment (approximately 1.2g / cm³), which is converted to the target ink weight (e.g., 12g for 10ml). The second preset weight is the acceptable threshold for the amount of ink to be dispensed. Because acrylic pigment is a suspension containing particles, its volume will change slightly due to factors such as temperature and stirring (e.g., the viscosity of the pigment increases at low temperatures, resulting in a higher mass for the same volume). If the volume is directly measured by the ink dispensing device (e.g., dispensing 10ml), it may lead to a deviation in the actual ink quality. However, by calculating the weight difference, regardless of the state of the acrylic pigment, the ink weight can accurately reflect the total mass of the injected pigment (e.g., if the target ink volume is 12g, as long as the weight difference reaches 12g, the total amount of pigment is ensured to be accurate), which better meets the production requirements of acrylic markers.

[0114] S400, after the second control information is executed, the control air extraction device connects the air extraction channel to the ink injection channel, extracts air from the storage space, and monitors the pressure data in real time.

[0115] It is understood that the completion of the second control information execution signifies that the ink filling device has stopped filling ink (ink weight meets the standard), and the ink filling channel and acrylic container space have been isolated (the ink filling channel and the connecting channel are isolated). The method of controlling the air extraction device to connect the air extraction channel and the ink filling channel can be by controlling the air extraction partition to open, thus connecting the air extraction channel and the ink filling channel. The method of extracting air from the storage container space can be by controlling the air extraction drive to extract air at a preset air extraction rate, or by searching a preset database using the specific acrylic marker model as an index to obtain the corresponding air extraction rate, and then controlling the air extraction drive to extract air at the retrieved rate, etc., but is not limited to these methods. The method of real-time pressure data monitoring can be by receiving air pressure data collected by a pressure acquisition device at a preset frequency, or by receiving data transmitted by the user, etc., but is not limited to these methods.

[0116] S500 obtains quality information based on pressure data; the quality information reflects whether the acrylic marker is up to standard after ink filling.

[0117] It is understandable that quality information obtained based on pressure data can be derived in several ways. For example, the pressure drop rate can be calculated from the pressure data during the suction process and compared with a preset drop rate to obtain quality information. Alternatively, pressure data can be sent to the user and then received from the user. However, this approach is not limited to these methods. By analyzing the pressure data during the suction and pressure holding processes, quality information obtained based on pressure data can determine whether the sealing performance of the storage section and the ink filling seal meets standards, thus preventing markers with poor sealing or excessive air residue from entering the market.

[0118] In one possible implementation, please refer to Figure 6 S500, based on pressure data, obtains quality information, including:

[0119] S510: When the monitored pressure data is less than the preset pressure, the pressure data is confirmed as pressure reduction data, and all pressure reduction data is confirmed as pressure reduction stage information; wherein, the pressure reduction data in the pressure reduction stage information are sorted in ascending order of monitoring time.

[0120] It is understandable that the preset pressure could be -0.085MPa, -0.09MPa, or obtained by searching the preset database using the specific model of the acrylic marker as an index, but it is not limited to these. When the monitored pressure data is lower than the preset pressure, confirming the pressure data as pressure reduction data can eliminate invalid data in the initial stage of air extraction (when the air extraction device is first started, the pressure data may still be at or near atmospheric pressure, and has not yet entered the effective stage of air discharge). Confirming all pressure reduction data as pressure reduction stage information can provide a basis for subsequent steps.

[0121] S520, based on the pressure reduction stage information, obtains pressure reduction analysis information; among which, the pressure reduction analysis information reflects whether the acrylic marker is of acceptable quality.

[0122] It is understandable that pressure reduction analysis information can be obtained based on pressure reduction stage information. This could involve calculating the pressure reduction rate (average pressure reduction rate) based on the pressure reduction stage information, then comparing the pressure reduction rate with a preset pressure reduction rate range to determine if the rate falls within that range. Alternatively, it could involve sending the pressure reduction stage information to the user and receiving data transmitted by the user, but is not limited to these methods. Pressure reduction analysis information obtained from pressure reduction stage information directly reflects the smoothness of air expulsion from the storage space during evacuation. If there are obvious gaps in the storage section or ink filling sealing section (such as injection molding defects or poor sealing of the ink filling section), external air will continuously seep in, leading to abnormal pressure reduction data (such as slow or stagnant pressure reduction).

[0123] In one possible implementation, please refer to Figure 6 S520, based on the pressure reduction stage information, obtains pressure reduction analysis information, including:

[0124] S521, the pressure reduction rate is obtained based on the pressure reduction stage information; wherein, the pressure reduction rate reflects the rate at which the pressure in the storage space decreases.

[0125] It is understandable that the pressure drop rate reflects the average rate of information during the pressure drop phase, indicating the magnitude of pressure decrease within the storage space per unit time. The pressure drop rate can be obtained from the pressure drop phase information by subtracting the first pressure drop data point from the last pressure drop data point, dividing by the time corresponding to the last pressure drop data point minus the time corresponding to the first pressure drop data point, and then taking the absolute value of the result. Alternatively, it can be obtained by sending the pressure drop phase information to the user and then receiving data transmitted by the user, but it is not limited to these methods.

[0126] For example, assuming the last pressure drop data in the pressure drop phase information is -0.092MPa, corresponding to a time of 15s, and the first pressure drop data in the pressure drop phase information is -0.082MPa, corresponding to a time of 5s, then the pressure drop rate = ((-0.092) - (-0.082)) / (15-5) = 0.001MPa / s.

[0127] S522, if the pressure reduction rate is less than the minimum value within the preset pressure reduction rate range, or the pressure reduction rate is greater than the maximum value within the preset pressure reduction rate range, then pressure reduction analysis information reflecting the substandard quality of the acrylic marker is obtained.

[0128] It is understandable that the preset pressure reduction rate range could be obtained by searching the preset database using the specific model of the acrylic marker as an index, or it could be obtained by receiving data transmitted by the user, but it is not limited to these. If the pressure reduction rate is lower than the lower limit of the range, it indicates that there may be a sealing defect in the pen holder (external air continues to seep in, negating the suction effect). If the pressure reduction rate is higher than the upper limit of the range, it indicates that the structure of the storage section or the ink filling seal may be damaged (such as cracks that allow air to escape without obstruction).

[0129] S523, if the pressure reduction rate is within the preset pressure reduction rate range, pressure reduction analysis information reflecting the qualified quality of the acrylic marker is obtained.

[0130] It is understandable that if the pressure drop rate is within the preset pressure drop rate range, it means that there are no obvious sealing defects in the storage section and the ink filling sealing section.

[0131] S530 generates a sub-control command when the pressure data equals the preset pressure; the sub-control command is used to control the air extraction device to stop extracting air from the storage space and to isolate the air extraction channel from the ink injection channel.

[0132] It is understandable that when the pressure data equals the preset pressure, it means that the residual air in the storage space has reached the expected level. The sub-control command controls the air extraction device to stop extracting air from the storage space and isolates the air extraction channel from the ink filling channel. This prevents excessive negative pressure in the storage space from damaging the storage section or the ink filling seal, thus providing environmental support for subsequent steps.

[0133] S540, after the sub-control command is executed, confirms the pressure data within the preset pressure holding time period as pressure holding data, and confirms all pressure holding data as pressure holding stage information.

[0134] It is understandable that the preset pressure holding time period can be 1 second, 2 seconds, or user-defined, but is not limited to these. The completion of the sub-control command indicates that the air extraction device has stopped extracting air and the air extraction channel and ink injection channel are isolated from each other, ensuring a stable pressure holding environment. Confirming all pressure holding data as pressure holding stage information provides a basis for subsequent steps.

[0135] S550, based on the pressure holding stage information, obtains pressure holding analysis information; among which, the pressure holding analysis information reflects whether the acrylic marker is of acceptable quality.

[0136] It is understandable that pressure holding analysis information can be obtained based on the pressure holding stage information. This could involve calculating the average pressure holding rate (the rate of pressure increase within the storage space per unit time) from the data within the pressure holding stage information, then comparing the average pressure holding rate with a preset rate to obtain the pressure holding analysis information. Alternatively, it could involve sending the pressure holding stage information to the user and receiving data transmitted by the user, but it is not limited to these methods. Pressure drop analysis can only identify obvious defects such as rapid air leakage during evacuation (e.g., obvious gaps), while pressure holding analysis information obtained from the pressure holding stage can discover hidden defects masked during the evacuation stage by analyzing pressure changes under static negative pressure, verifying the long-term effectiveness of the seal, and better matching the user's actual usage scenarios.

[0137] In one possible implementation, please refer to Figure 6 S550, based on the pressure holding stage information, obtains pressure holding analysis information, including:

[0138] S551, the holding pressure rate is obtained based on the holding pressure stage information; wherein, the holding pressure rate reflects the rate of pressure increase within the storage space.

[0139] It is understandable that the holding pressure rate can be obtained based on the holding pressure phase information. This could be achieved by subtracting the value of the first holding pressure data from the last holding pressure data in the holding pressure phase information, dividing by the time corresponding to the last holding pressure data subtracting the time of the first holding pressure data pair, and then taking the absolute value of the result. Alternatively, it could be obtained by sending the holding pressure phase information to the user and then receiving the data transmitted by the user, but it is not limited to these methods. Obtaining the holding pressure rate based on the holding pressure phase information provides a basis for subsequent steps.

[0140] For example, assuming the value of the first pressure holding data in the pressure holding stage information is -0.09 MPa and the corresponding time is 0, and the value of the last pressure holding data in the pressure holding stage information is -0.083 MPa and the corresponding time is 60, then the pressure holding rate = (-0.083 - (-0.09)) / (60 - 0) ≈ 0.000117 MPa / s.

[0141] S552, if the holding pressure rate is less than or equal to the preset holding pressure rate, then the holding pressure analysis information reflecting that the acrylic marker is of acceptable quality is obtained; if the holding pressure rate is greater than the preset holding pressure rate, then the holding pressure analysis information reflecting that the acrylic marker is of unacceptable quality is obtained.

[0142] It is understandable that if the holding pressure rate is less than or equal to the preset holding pressure rate, it means that external air infiltration is extremely slow, and there are no hidden gaps (such as micro-cracks in injection molding or poor adhesion of the ink filling seal) or the defects are so small as to be negligible. If the holding pressure rate is greater than the preset holding pressure rate, it means that there may be hidden gaps in the storage section and / or the ink filling seal.

[0143] S560, if both the pressure reduction analysis information and the pressure holding analysis information indicate that the acrylic marker is of acceptable quality, then quality information indicating that the acrylic marker is of acceptable quality is obtained; if the pressure reduction analysis information and / or the pressure holding analysis information indicate that the acrylic marker is of unacceptable quality, then quality information indicating that the acrylic marker is of unacceptable quality is obtained.

[0144] Understandably, by analyzing the pressure reduction and pressure holding separately, the dynamic air extraction sealing performance and the static pressure holding sealing performance can be verified simultaneously, covering the blind spots of screening for both explicit and implicit sealing defects, and reducing the possibility of substandard acrylic markers entering the market.

The control unit may be disposed on the mounting component and communicate with the fixing clamping device, the ink-filling device, and the air extraction device.
