Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of propylene marker pen manufacturing, and particularly relates to a propylene marker pen ink injection equipment and method. BACKGROUND

[0002] A propylene marker pen is a drawing tool taking propylene pigment as a core ink component and combining with the convenient writing and drawing form of a marker pen. Compared with ordinary marker pens (such as alcohol marker pens and water-based marker pens), the propylene marker pen can be applied to carriers of various materials (paper, cloth, wood, metal, ceramic and plastic) due to the characteristics of propylene pigment.

[0003] The existing propylene marker pen ink injection mode is usually to first inject ink into a pen barrel through an opening away from a pen tip end of the pen barrel, and then to seal the opening by adding a pen tail through a machine device. The large-capacity propylene marker pen produced by this ink injection mode will have a certain amount of air remaining in the pen barrel. In addition, in the process of use, as the propylene pigment decreases, the air in the pen barrel gradually increases through the siphon effect of the pen tip, and the unqualified pen barrel (with a small gap) will also make the external air enter the pen barrel, so that the propylene pigment in the pen barrel reacts with the air to cause the propylene pigment to dry, skin or oxidize and discolor, affecting the user experience. SUMMARY

[0004] The propylene marker pen ink injection equipment and method provided by the embodiments of the present application can improve the technical problem that the air reacts with the propylene pigment to cause the propylene pigment to dry, skin or oxidize and discolor in the related art.

[0005] In a first aspect, the embodiments of the present application provide a propylene marker pen ink injection equipment for injecting ink into a propylene marker pen. The propylene marker pen includes a storage part and an ink injection sealing part, and the storage part and the ink injection sealing part jointly form a storage containing space. The ink injection sealing part has at least one first ink injection hole communicating with the storage containing space. The propylene marker pen ink injection equipment includes: a mounting piece; a fixed clamping device arranged on the mounting piece and used for fixing the propylene marker pen and acquiring the weight of the propylene marker pen in real time; and an ink injection device arranged on the mounting piece and having a propylene containing space, an ink injection channel communicating with the propylene containing space, and at least one second ink injection hole communicating with the ink injection channel. The propylene containing space is used for storing propylene ink. The ink injection device is used for being close to and abutting against the ink injection sealing part to inject ink into the storage containing space through the propylene containing space, the ink injection channel, the second ink injection hole and the first ink injection hole; and An air extraction device is arranged on the mounting member and has an air extraction channel that is in communication with the ink injection channel, and the air extraction device is configured to extract air in the storage space through the air extraction channel and the ink injection channel.

[0006] The technical solutions described above in the embodiments of the present application have at least the following technical effects: The propylene marker pen ink injection equipment provided in the embodiments of the present application forms a storage space for storing propylene ink through the storage part and the ink injection sealing part, so that the propylene marker pen after ink injection can realize the sealing of the storage space without an additional sealing process, thereby improving the problem that in the traditional ink injection process, the ink injection is first performed through the opening of the pen barrel far from the pen tip, and then the sealing is performed through another device, which may cause the external impurities to enter the pen barrel and pollute the ink. The fixed clamping device ensures that the marker pen does not displace during ink injection, and accurately controls the amount of ink injection, thereby reducing the possibility that the sealing and the anti-oxidation effect are affected by excessive, insufficient or position deviation of the ink. The ink injection device delivers the ink to the storage space in a sealed manner through the sealing contact and the directional channel (the ink injection channel, the second ink injection hole and the first ink injection hole), thereby avoiding the mixing of air during the ink injection process. The air extraction device removes the air in the storage space (including the original air in the storage space before ink injection, and the trace of air that may be mixed during the ink injection process) in a negative pressure air extraction manner, thereby improving the technical problem that in the related art, the air reacts with the propylene pigment to cause the propylene pigment to dry, form a skin or be oxidized and discolored.

[0007] In a second aspect, the embodiments of the present application provide a propylene marker pen ink injection method applied to the propylene marker pen ink injection equipment described in the first aspect, and the method comprises the following steps. When the propylene marker pen is located at a preset position, the ink injection device is controlled to be close to and in contact with the ink injection sealing part; wherein the preset position is the position of the propylene marker pen when it is fixed by the fixed clamping device; The fixed clamping device is used to monitor the weight data in real time; wherein the weight data reflects the weight of the propylene marker pen; The first control information and the 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; After the second control information is executed, the air extraction device is controlled to connect the air extraction channel and the ink injection channel, extract the air in the storage space, and monitor the pressure data in real time; Quality information is obtained based on the pressure data; wherein the quality information reflects whether the quality of the propylene marker pen after ink injection is qualified.

[0008] The technical solutions described above in the embodiments of the present application have at least the following technical effects: By controlling the ink injection device to approach and abut the ink injection sealing part, a closed ink injection channel is formed to block external air from entering the storage containing space through the ink injection port, avoid air mixing with ink during the ink injection process, and reduce air residues in the storage containing space. Then, the fixed clamping device is used to monitor weight data in real time, quantify the ink injection amount according to the weight change, and solve the problem of roughness in the traditional ink injection process by judging the ink injection amount by experience. Then, the first control information and the second control information are obtained based on the weight data, the weight monitoring data is converted into the ink injection action executed by the control device, and manual operation is replaced to avoid human errors. Then, 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 air in the storage containing space, and monitor pressure data in real time to remove residual air in the storage containing space after ink injection, reduce the air content in the storage containing space, and thus reduce the possibility of drying, skinning, and oxidation discoloration of the propylene pigment caused by contact with air. At the same time, according to the pressure data, excessive air extraction is avoided to form a large negative pressure in the storage containing space to prevent water evaporation in the propylene pigment. Finally, the quality information is obtained based on the pressure data, the pressure change rule in the storage containing space is detected to detect the sealing performance of the pen barrel, and the possibility of pigment deterioration (drying, skinning, and oxidation discoloration) caused by external air entering the pen barrel through a gap during user use is reduced to affect user experience.

[0019] Acrylic marker is a drawing tool that takes acrylic pigment as the core ink component and combines the convenient writing and drawing form of a marker. Compared with ordinary markers (such as alcohol markers and water-based markers), acrylic markers can be applied to carriers of various materials (paper, cloth, wood, metal, ceramic, plastic, etc.) due to the characteristics of acrylic pigment.

[0020] The existing acrylic marker ink injection method is usually to inject ink into the pen barrel through the opening away from the pen tip end of the pen barrel, and then to seal the opening by adding a pen tail to the machine equipment. The large-capacity acrylic marker produced by this ink injection method will have a certain amount of air (air in the gap between the ink and the pen barrel) remaining in the pen barrel. In addition, during the use of the acrylic marker, as the pigment decreases, the air in the pen barrel gradually increases through the siphon effect of the pen tip, and the unqualified pen barrel (with a small gap) will also allow external air to enter the pen barrel, so that the acrylic pigment in the pen barrel reacts with the air, causing the acrylic pigment to dry, skin, or oxidize and discolor, affecting the user experience.

[0021] Based on this, in order to improve the technical problems in the related art that air reacts with propylene pigments to cause the propylene pigments to dry, form a skin, or discolor, embodiments of the present application provide the following solutions.

[0022] Please refer to Figure 1 The propylene marker ink filling device 100 is used for filling ink for the propylene marker 200, the propylene marker 200 includes a storage part 60 and an ink filling sealing part 50, the storage part 60 and the ink filling sealing part 50 jointly form a storage containing space 61, the ink filling sealing part 50 has at least one first ink filling hole 511 communicating with the storage containing space 61, and the propylene marker ink filling device 100 includes a mounting part 10, a fixed clamping device 20, an ink filling device 30, and an air extraction device 40, wherein: The fixed clamping device 20 is arranged on the mounting part 10 and is used for fixing the propylene marker 200 and acquiring the weight of the propylene marker 200 in real time.

[0023] The ink filling device 30 is arranged on the mounting part 10 and has a propylene containing space, an ink filling channel 321 communicating with the propylene containing space, and at least one second ink filling hole 322 communicating with the ink filling channel 321, the propylene containing space is used for storing propylene ink, and the ink filling device 30 is used for being close to and abutting against the ink filling sealing part 50 to fill ink into the storage containing space 61 through the propylene containing space, the ink filling channel 321, the second ink filling hole 322, and the first ink filling hole 511.

[0024] The air extraction device 40 is arranged on the mounting part 10 and has an air extraction channel, the air extraction channel is communicated with the ink filling channel 321, and the air extraction device 40 is used for extracting air in the storage containing space 61 through the air extraction channel and the ink filling channel 321.

[0025] It can be understood that the storage part 60 is a tubular structure capable of jointly forming the storage containing space 61 with the ink filling sealing part 50 to store propylene pigments, for example, the storage part 60 can be a plastic tube, an aluminum tube, etc., but is not limited thereto.

[0026] The ink filling sealing part 50 is a device having the functions of an ink filling interface and sealing the storage containing space 61, for example, the ink filling sealing part 50 can include a cover and a solenoid valve, the cover is arranged on the storage part 60 and has the first ink filling hole 511, and the solenoid valve is arranged on the cover and is used for plugging or opening the first ink filling hole 511, etc., but is not limited thereto.

[0027] The mounting part 10 is a device used for fixing the relative positions of the fixed clamping device 20, the ink filling device 30, and the air extraction device 40 and providing stable support for coordinated action, for example, the mounting part 10 can be an aluminum mounting rack, a copper mounting rack, etc., but is not limited thereto.

[0028] The fixed clamping device 20 is a device capable of realizing accurate fixing of the marker pen and real-time monitoring of the ink injection amount. For example, the fixed clamping device 20 can include a weighing device (an electronic platform scale, a belt scale, etc.) and a clamping device (a pneumatic clamping device, an electric clamping device, etc.). The weighing device can be arranged on the mounting piece 10, and the clamping device can be arranged on the mounting piece 10, used for clamping the acrylic marker pen 200 and moving the acrylic marker pen 200 to the weighing device.

[0029] The ink injection device 30 is a device capable of delivering acrylic ink to the storage containing space 61 through sealing contact and directional channel, while avoiding air mixing during ink injection. For example, the ink injection device 30 can include an acrylic storage tank (an aluminum storage tank, a plastic storage tank, etc.), a driving cylinder (a straight rod cylinder, a double-acting cylinder, etc.), and an ink injection pipe (an aluminum pipe, a plastic pipe, etc.). The acrylic storage tank can be arranged on the mounting piece 10 and has an acrylic containing space. The driving cylinder can be arranged on the mounting piece 10 and located above the fixed clamping device 20. The ink injection pipe can be arranged on the power output end of the driving cylinder and has an ink injection channel 321 and a second ink injection hole 322. The acrylic containing space can be connected to the ink injection channel 321 through a flexible pipe long enough (the flexible pipe will not be stretched when the driving cylinder drives the ink injection pipe to move). The driving cylinder is used to drive the ink injection pipe to approach and contact the ink injection sealing part 50 to connect the ink injection channel 321 and the storage containing space 61, but is not limited thereto.

[0030] The air extraction device 40 is a device that extracts air in the storage containing space 61 through communication 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 thereto.

[0031] As can be seen from the foregoing, the acrylic marker refilling device 100 provided in the present embodiment forms a storage space 61 for storing acrylic ink through the storage portion 60 and the ink filling seal 50. This allows the acrylic marker 200 to be sealed after filling without requiring an additional sealing process. This improves the conventional refilling process, which involves first filling ink through an opening at the end of the pen barrel away from the tip and then sealing it with a separate device, potentially leading to the entry of foreign matter into the pen barrel and contaminating the ink. The fixed clamping device 20 ensures that the marker does not move during the refilling process and precisely controls the amount of ink filled, reducing the possibility of overfilling, underfilling, or positional displacement affecting the sealing and anti-oxidation properties. The refilling device 30 delivers ink to the storage space 61 through sealed interference and directional channels (the refilling channel 321, the second refilling port 322, and the first refilling port 511), preventing the intrusion of air during the refilling process. The air in the storage and accommodating space 61 (including the original air in the storage and accommodating space 61 before ink filling, the trace amount of air that may be mixed in during the ink filling process, etc.) is removed by the vacuum device 40 by negative pressure vacuuming, thereby improving the technical problem in the related art that the air reacts with the acrylic paint, causing the acrylic paint to dry, form a skin, or oxidize and discolor.

[0032] In some embodiments, please refer to Figure 2 and Figure 3 The ink injection sealing portion 50 includes a fixed part 51 , a movable part 52 and an elastic part 53 .

[0033] The fixing member 51 is disposed on the storage portion 60 . The fixing member 51 has a first ink injection hole 511 and a movable accommodating space 512 . The movable accommodating space 512 has a first position 513 and a second position 514 .

[0034] The movable part 52 is located in the movable accommodating space 512 and is movably arranged on the fixed part 51. A third ink injection hole 521 corresponding to the first ink injection hole 511 is opened on the movable part 52, and an elastic movable space 522 is formed between the fixed part 51 and the movable part 52.

[0035] The elastic member 53 is located in the elastic movable space 522 , and two ends of the elastic member 53 are connected to the fixed member 51 and the movable member 52 respectively.

[0036] The fixed part 51 and the storage part 60 jointly form a storage containing space 61, and the elastic part 53 is used to drive the movable part 52 to approach the first position 513. When the movable part 52 is at the first position 513, the first ink injection hole 511 is not communicated with the third ink injection hole 521. The ink injection device 30 is used to approach and abut against the movable part 52, and drive the movable part 52 to approach the second position 514. When the movable part 52 is at the second position 514, the first ink injection hole 511 is communicated with the third ink injection hole 521. The ink injection device 30 injects ink into the storage containing 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.

[0037] It can be understood that the fixed part 51 serves as a fixed basis of the ink injection sealing part 50, connects the storage part 60 to form a closed storage containing space 61, and provides the first ink injection hole 511 and the movable containing space 512. For example, the material of the fixed part 51 can be polyethylene, polypropylene or the like, but is not limited thereto.

[0038] The movable part 52 realizes the on-off of the first ink injection hole 511 and the third ink injection hole 521 through axial movement. When not injecting ink, the movable part 52 blocks the channel to prevent air from entering. When injecting ink, the movable part 52 conducts the channel to supply ink. For example, the material of the movable part 52 can be polyethylene, polypropylene or the like, but is not limited thereto.

[0039] The elastic part 53 drives the movable part 52 to always remain at the first position 513 (sealed state when not injecting ink) through elastic deformation, ensures that the first ink injection hole 511 and the third ink injection hole 521 are always disconnected during the ink injection process, and prevents air from entering the storage containing space 61 from the structure. For example, the elastic part 53 can be a cylindrical spiral compression spring, a disc spring or the like, but is not limited thereto.

[0040] In this way, in the non-ink filling state (daily storage and transportation), the elastic member 53 drives the movable member 52 to be located at the first position 513, the third ink filling hole 521 of the movable member 52 is completely offset from the first ink filling hole 511 of the fixed member 51, the storage containing space 61 is blocked from the outside through the first ink filling hole 511, and the outside air is prevented from entering the storage containing space 61 through the third ink filling hole 521 and the first ink filling hole 511; in the ink filling state, the ink filling member 32 of the ink filling device is close to and abuts against the abutting end of the movable member 52 and applies an axial pushing force, the axial pushing force drives the movable member 52 to move axially along the movable containing space 512 to the second position 514, the elastic member 53 is compressed, the third ink filling hole 521 is completely aligned with the first ink filling hole 511, at the same time, the second ink filling hole 322 of the ink filling member 32 is docked with the third ink filling hole 521, the ink filling device fills the ink into the storage containing space 61 through the ink filling channel 321, the second ink filling hole 322, the third ink filling hole 521 and the first ink filling hole 511, realizes the non-leakage ink filling, and prevents the external impurities from entering the storage containing space 61 in the process of ink filling; after the ink filling is completed, the ink filling member 32 is away from the movable member 52, the elastic force of the elastic member 53 releases and pushes the movable member 52 to move reversely along the movable containing space 512 to the first position 513, the first ink filling hole 511 is offset from the third ink filling hole 521, the storage containing space 61 returns to the sealed state, the outside air is prevented from entering after the ink filling, and the risk of air backflow when the ink filling device is pulled out is reduced.

[0041] In some embodiments, please refer to Figures 1 to 3 , the ink filling device 30 comprises a storage injection mechanism 31, an ink filling member 32, an ink filling pipeline 33, an ink filling partition member 34 and an ink filling driving member 35.

[0042] The storage injection mechanism 31 is arranged on the mounting member 10 and has a propylene containing space.

[0043] The ink filling member 32 has an ink filling channel 321, a second ink filling hole 322 is arranged on the side of the ink filling member 32 away from the storage injection mechanism 31, the ink filling member 32 is recessed inwardly at the end away from the storage injection mechanism 31 to form a flow guide part 323, a flow guide space 324 which is in communication with the ink filling channel 321 is formed between the periphery of the flow guide part 323 and the inner wall of the ink filling member 32, and the second ink filling hole 322 is in communication with the flow guide space 324.

[0044] The ink filling pipeline 33 has a connecting channel, and the two ends of the ink filling pipeline 33 are connected with the storage injection mechanism 31 and the ink filling member 32 respectively, and the connecting channel is in communication with the propylene containing space and the ink filling channel 321 at the same time.

[0045] The ink filling partition member 34 is arranged on the ink filling member 32 and is used for making the connecting channel and the ink filling channel 321 communicate with each other or be blocked.

[0046] The ink injection driving member 35 is arranged on the mounting member 10, and the ink injection member 32 is arranged on the power output end of the ink injection driving member 35. The ink injection driving member 35 is used to drive the ink injection member 32 to approach and abut against the ink injection sealing part 50, so that the ink injection channel 321 is connected with the storage containing space 61 through the flow guiding space 324, the second ink injection hole 322 and the first ink injection hole 511.

[0047] It can be understood that the storage injection mechanism 31 serves as a storage and preliminary conveying device for propylene ink, and provides continuous and stable ink supply for the ink injection process, while avoiding oxidation and deterioration caused by long-term contact of ink with air. For example, the storage injection mechanism 31 can include a sealed storage tank (an aluminum storage tank, a plastic storage tank, etc.) and an air pressure balancing valve. The sealed storage tank can be arranged on the mounting member 10 and has a propylene containing space. The air pressure balancing valve can be arranged on the sealed storage tank and is used to supplement air during ink injection (to avoid negative pressure in the propylene containing space causing the ink to be unable to flow out).

[0048] The ink injection member 32 is a tubular structure that realizes uniform conveying of ink through the ink injection channel 321 and the flow guiding part 323 and flow guiding space, and forms a sealed abutment with the ink injection sealing part 50. The flow guiding part 323 can be conical, hemispherical, etc. The vertex of the flow guiding part 323 is directed towards the inside of the ink injection channel 321, and the circumferential side forms an annular flow guiding space 324 with the inner wall of the ink injection member 32, but is not limited thereto. For example, the ink injection member 32 can be an aluminum pipe, a plastic pipe, etc., but is not limited thereto.

[0049] The ink injection pipeline 33 connects the storage injection mechanism 31 and the ink injection member 32, and constructs a closed ink conveying path to avoid contact of ink with air or leakage during conveying. For example, the ink injection pipeline 33 can be a polyurethane steel wire pipe, a Teflon hose, etc., but is not limited thereto.

[0050] The ink injection cutoff member 34 controls the on-off connection between the connecting channel and the ink injection channel 321, realizes time sequence cooperation of cutoff during air extraction and connection during ink injection, and avoids air from the storage injection mechanism 31 entering the ink injection channel 321 during air extraction. The ink injection cutoff member 34 can also be arranged on the storage injection mechanism 31. For example, the ink injection cutoff member 34 can be a direct-acting electromagnetic valve, a pilot-operated electromagnetic valve, etc., but is not limited thereto.

[0051] The ink injection driving member 35 drives the ink injection member 32 to move in the axial direction, realizes precise abutment (controllable force) with the ink injection sealing part 50, and at the same time ensures the alignment accuracy of the ink injection hole. For example, the ink injection driving member 35 can be a driving air cylinder, a driving motor, etc., but is not limited thereto.

[0052] In this way, the ink injection member 32 is driven by the ink injection driving member 35 to move towards the ink injection sealing part 50 until the ink injection member 32 is in close contact with the movable part 52 and the contact pressure reaches the preset value. During the ink injection stage, the ink injection partition member 34 connects the ink injection channel 321 and the connecting channel, and the ink stored in the injection mechanism 31 is injected into the storage containing space 61 through the connecting channel, the ink injection channel 321, the flow guide space 324, the second ink injection hole 322, the third ink injection hole 521 and the first ink injection hole 511 under the action of gravity and / or pressure, and the weight change is monitored in real time by the fixed clamping device 20, and when the weight reaches the target ink injection amount, the ink injection partition member 34 disconnects the ink injection channel 321 and the connecting channel, and the ink injection is stopped. After the air extraction process is completed, the ink injection driving member 35 drives the ink injection member 32 to move reversely and separate from the ink injection sealing part 50.

[0053] In some embodiments, referring to Figure 1 , the air extraction device 40 includes an air extraction conveying member 41, an air extraction partition member 42, a pressure collecting member 43 and an air extraction driving member 44.

[0054] The air extraction conveying member 41 has an air extraction channel, one end of the air extraction conveying member 41 is connected with the ink injection member 32, and the air extraction channel is connected with the ink injection channel 321.

[0055] The air extraction partition member 42 is arranged on the air extraction conveying member 41 close to one end of the ink injection member 32, and is used to disconnect or connect the air extraction channel and the ink injection channel 321.

[0056] The pressure collecting member 43 is arranged in the ink injection channel 321 and on the ink injection member 32, and is used to monitor the pressure in the storage containing space 61 in real time when the ink injection channel 321 is connected with the storage containing space 61 and the connecting channel is disconnected with the ink injection channel 321.

[0057] The air extraction driving member 44 is arranged on the mounting member 10 and connected with the other end of the air extraction conveying member 41, and is used to extract the air in the storage containing space 61 through the air extraction channel, the ink injection channel 321, the flow guide space 324, the second ink injection hole 322 and the first ink injection hole 511.

[0058] It can be understood that the air extraction conveying member 41 connects the ink injection member 32 and the air extraction driving member 44 to build a closed air extraction path, so as to ensure that the air in the storage containing space 61 can be directed and discharged without leakage. For example, the air extraction conveying member 41 can be a hard conveying pipe, a rubber conveying hose and the like, but is not limited thereto.

[0059] The air extraction partition member 42 controls the on-off of the air extraction channel and the ink injection channel 321, realizes the timing cooperation of connection during air extraction, disconnection during ink injection and idling, and avoids the ink flowing into the air extraction system during ink injection. For example, the air extraction partition member 42 can be a direct-acting electromagnetic valve, a pilot-operated electromagnetic valve and the like, but is not limited thereto.

[0060] The pressure collection member 43 monitors the pressure change in the storage containing space 61 in real time through the ink injection channel 321, and provides accurate control basis for the air extraction driving member 44. For example, the pressure collection member 43 can be a miniature negative pressure sensor, a composite pressure sensor, etc., but is not limited thereto.

[0061] The air extraction driving member 44 provides continuous and adjustable air extraction power, and extracts the air in the storage containing space 61 through the air extraction channel. For example, the air extraction driving member 44 can be an oil-free miniature vacuum pump, a reciprocating vacuum pump, etc., but is not limited thereto.

[0062] In this way, in the air extraction stage, the ink injection partition member 34 connects the ink injection channel 321 with the connecting channel, and the air extraction driving member 44 discharges the air in the storage containing space 61 through the first ink injection hole 511, the third ink injection hole 521, the second ink injection hole 322, the flow guide space 324, the ink injection channel 321 and the air extraction channel, so as to reduce the residual amount of air in the storage containing space 61, thereby prolonging the drying and skinning time, reducing the oxidation and discoloration rate, and automatically starting and stopping or adjusting the air extraction power according to the pressure data collected by the pressure collection member 43 in real time. The air extraction partition member 42 connects the air extraction channel with the ink injection channel 321, instead of separately providing an air extraction port, thereby reducing equipment redundancy and ensuring the sealing of the channel by multiplexing the existing ink injection channel 321.

[0063] By pre-extracting the air in the storage containing space 61, the storage containing space 61 is in a nearly saturated state of “pigment filling + a small amount of residual air” (without obvious “air cavity”). When the siphon effect starts to work and the pigment flows to the pen tip, the change in the storage containing space 61 is that the pigment flows out of the storage containing space 61 and the gap between the pigment and the storage part 60 increases slightly. However, since the air content in the gap is small, the gap will not be filled with air immediately, but a “low negative pressure” (the negative pressure value is very low, only a little lower than the external atmospheric pressure) will be formed first. Since the external air needs to break through the resistance of the pen tip to enter the storage containing space 61 (the resistance of the pen core structure and the viscosity resistance of the pigment itself), the difference between the external atmospheric pressure and the negative pressure in the storage containing space 61 is very small in the “low negative pressure” stage, and the external air can only slowly and in small amounts penetrate. Before the pressure in the storage containing space 61 reaches the external atmospheric pressure, the penetration speed of the external air is less than the penetration speed of the external air when the pressure in the storage containing space 61 is equal to the external atmospheric pressure. Therefore, the formation of low negative pressure by pre-extracting the air in the storage containing space 61 can delay the time for the external air to enter the storage containing space 61, thereby solving the technical problems of the related art that the reaction between air and acrylic pigment causes the acrylic pigment to dry, skin or oxidize and discolor.

[0064] For example, the ink filling process and the air extraction process can be alternately performed. For example, a plurality of weight values and a plurality of air pressure values can be preset according to the volume of the storage space 61. During the ink filling process, when the weight monitored by the fixed 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 is used to extract part of the air in the storage space 61 and monitor the air pressure in the storage space 61 in real time. When the monitored air pressure in the storage 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. In this way, the weight and the air pressure in the storage space 61 can be monitored until they reach the preset corresponding standard values. In this way, compared with the case where the weight and the air pressure in the storage space 61 are monitored until they reach the preset corresponding standard values by only one ink filling process and one air extraction process, the influence of the air pressure in the storage space 61 on the ink filling process (the air pressure in the storage space 61 increases with the increase of the ink in the storage space 61) can be reduced, and the ink filling process can be more stable.

[0065] In some embodiments, referring to Figure 1 , the fixed clamping device 20 includes a weighing mechanism 21 and a clamping mechanism 22.

[0066] The weighing mechanism 21 is arranged on the mounting member 10 and is used to obtain the weight of the propylene marker pen 200.

[0067] The clamping mechanism 22 is arranged on the mounting member 10 and is used to fix the propylene marker pen 200 on the weighing mechanism 21 and limit the movement of the propylene marker pen 200 in the horizontal direction.

[0068] It can be understood that the weighing mechanism 21 collects the weight change of the propylene marker pen 200 before and after the ink filling in real time, thereby 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 thereto.

[0069] The clamping mechanism 22 is used to fix the propylene marker pen 200 on the weighing mechanism 21 and make the propylene marker pen 200 be located directly below the ink filling member 32, and limit the movement and rotation of the propylene marker pen 200 in the horizontal direction, so as to ensure that the first ink filling hole 511 and the second ink filling hole 322 are accurately aligned during the ink filling, and avoid the sealing failure or ink leakage caused by the inclination of the pen body when the ink filling member 32 is abutted. For example, the clamping mechanism 22 can be symmetrical clamping jaws, parallel clamping jaws, etc., but is not limited thereto.

[0070] In this way, the propylene marker pen 200 (with the tip pointing downward and the ink sealing part 50 pointing upward) is transported to the side of the clamping mechanism 22 or the weighing mechanism 21 by one of manual operation, a conveyor belt or a vibrating feeding device, and then the propylene marker pen 200 on the side is clamped and moved to the weighing mechanism 21 or fixed on the weighing mechanism 21 by the clamping mechanism 22. After the ink refilling process and the air extraction process, the clamping mechanism 22 can move the propylene marker pen 200 on the weighing mechanism 21 to the conveyor belt on the side, or release the propylene marker pen 200 for manual transfer, or move the propylene marker pen 200 with unqualified quality to a pre-divided recycling area, etc.

[0071] Please refer to Figure 4 The application also provides a propylene marker pen ink refilling method, which is applied to the propylene marker pen ink refilling device 100 described above, and the propylene marker pen ink refilling method comprises the following steps. When the propylene marker pen is in a preset position, the ink refilling device is controlled to approach and contact the ink sealing part; wherein the preset position is the position of the propylene marker pen when it is fixed by the fixed clamping device.

[0072] The weight data is monitored in real time by the fixed clamping device; wherein the weight data reflects the weight of the propylene marker pen.

[0073] The first control information and the 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 refilling device.

[0074] After the second control information is executed, the air extraction device is controlled to connect the air extraction channel and the ink refilling channel, extract the air in the storage space, and monitor the pressure data in real time.

[0075] The quality information is obtained based on the pressure data; wherein the quality information reflects whether the quality of the propylene marker pen after ink refilling is qualified.

[0076] From the above, the propylene marker ink injection method provided by the embodiment of the application can form a closed ink injection channel by controlling the ink injection device to approach and abut the ink injection sealing part, block the external air from entering the storage containing space through the ink injection port, avoid the air from mixing with the ink during the ink injection process, and reduce the residual air in the storage containing space. Then, the fixed clamping device is used to monitor the weight data in real time, the ink injection amount is quantified according to the weight change, the problem of roughness of the traditional ink injection process is solved, and the ink injection amount is determined by experience. Based on the weight data, the first control information and the second control information are obtained, the weight monitoring data is converted into the ink injection action performed by the control device, the manual operation is replaced, and the human error is avoided. After the second control information is executed, the air extraction device is controlled to connect the air extraction channel and the ink injection channel, extract the air in the storage containing space, monitor the pressure data in real time, remove the residual air in the storage containing space after the ink injection, reduce the air content in the storage containing space, thereby reducing the possibility of drying, skinning and oxidation discoloration of propylene pigments caused by contact with air, and avoiding excessive air extraction to form a large negative pressure in the storage containing space according to the pressure data, preventing the evaporation of water in the propylene pigments. Finally, the quality information is obtained based on the pressure data, the sealing performance of the pen barrel is detected by the pressure change rule in the storage containing space, and the possibility of the deterioration (drying, skinning and oxidation discoloration) of the pigments caused by the entry of external air into the pen barrel through the gap during the use of the user is reduced, and the user experience is affected.

[0077] In order to better understand the propylene marker ink injection method provided by the embodiment of the application, the specific implementation process of the propylene marker ink injection method provided by the embodiment of the application will be exemplarily introduced below.

[0078] Figure 4 The schematic flowchart of the propylene marker ink injection method provided by the embodiment of the application is shown, and the propylene marker ink injection method comprises: S100, when the propylene marker is located at a preset position, the ink injection device is controlled to approach and abut the ink injection sealing part; wherein the preset position is the position of the propylene marker when the propylene marker is fixed by the fixed clamping device.

[0079] It can be understood that the way to determine whether the propylene marker is located at the preset position can be that the propylene marker is determined to be located at the preset position when the weight data transmitted by the fixed clamping device in real time is stable and the value of the weight data is equal to the preset weight of the marker, but is not limited thereto. The image acquisition device (digital camera, infrared camera, etc.) arranged on the mounting member, etc. can also be used. The control of the ink injection device close to and in contact with the ink injection sealing part can be that the ink injection driving member drives the ink injection part to move close to and in contact with the ink injection sealing part at a preset speed, or the distance sensor arranged on the ink injection part can be used to monitor the distance between the ink injection part and the ink injection sealing part in real time, and the movement speed of the ink injection part can be controlled according to the distance (the ink injection part and the ink injection sealing part are controlled to move at a first preset speed when the distance between them is greater than a preset distance, the ink injection part and the ink injection sealing part are controlled to move at a second preset speed when the distance between them 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 thereto.

[0080] S200, monitoring the weight data in real time through the fixed clamping device; wherein the weight data reflects the weight of the propylene marker.

[0081] It can be understood that the weight data is monitored in real time through the fixed clamping device, the weight change of the pen body is captured in real time, data support is provided for subsequent accurate control of the ink injection amount and prevention of ink waste or deficiency, and the sealing and stability of the ink injection process are ensured at the same time.

[0082] S300, obtaining first control information and second control information based on the weight data; the first control information and the second control information are used to control the ink injection device.

[0083] It can be understood that the way to obtain the first control information based on the weight data can be that a first preset weight threshold (the total weight of the ink filling device and the ink filling seal part when the propylene marker is stably fixed (including the weight of the pen body and the weight of the ink filling device after the abutment)) is taken as a reference, and when the weight data reaches the first preset weight (indicating that the preparation work (positioning, sealing) before ink filling is completed), the first control information for controlling the ink filling device to stop moving and filling ink into the storage space of the marker is obtained. The way to obtain the second control information based on the weight data can be that the weight of the ink filling device is monitored in real time, and when the weight of the ink reaches a preset ink weight, the second control information for controlling the ink filling device to stop filling ink into the storage space is obtained. The first control information and the second control information obtained based on the weight data can automatically trigger the actions of starting ink filling, stopping ink filling and isolating the channel (controlling the ink filling isolation member to isolate or connect the channel and the ink filling channel) of the ink filling device through the dynamic change of the weight data, realize the automatic control of the ink filling process, avoid the error of manual operation, and at the same time ensure the accuracy of the ink filling amount and the airtightness of the ink filling environment.

[0084] In a possible implementation manner, referring to Figure 5 , S300, obtaining the first control information and the second control information based on the weight data, comprising: S310, obtaining an initial weight; wherein the initial weight is the weight data when the propylene marker is located at a preset position.

[0085] It can be understood that the way to obtain the initial weight can be that the real-time monitoring weight data is confirmed as the initial weight when the propylene marker is located at the preset position, has not been filled with ink, and the fixed clamping device does not appear fluctuation in the real-time monitoring weight data, or the like, but is not limited thereto. Obtaining the initial weight can provide a basis for subsequent steps.

[0086] S320, generating the first control information when the weight data reaches a first preset weight; wherein the first control information is used to control the ink filling device to stop moving and fill ink into the storage space.

[0087] It can be understood that the first preset weight is a total weight reflecting that the ink filling device and the ink filling sealing part are completely fitted and the propylene marker is stably fixed. The first preset weight can be set by the user or can be obtained by searching the model of the propylene marker in need of ink filling in a preset database, but is not limited thereto. When the weight data reaches the first preset weight, first control information for controlling the ink filling device to stop moving and filling ink into the storage containing space is generated, thereby reducing the possibility of damage to the ink filling sealing part (such as cracking of the fixed part or the movable part) or deformation of the storage part (especially the storage part made of plastic) due to excessive extrusion.

[0088] S330, the value obtained by subtracting the initial weight from the real-time monitored weight data is confirmed as the ink weight.

[0089] It can be understood that the ink weight is confirmed in real time by calculation, which provides a basis for subsequent judgment of whether the ink filling amount meets the standard.

[0090] For example, assuming that the initial weight is 50g and the weight data detected at a certain time is 55g, the ink weight = 55-50 = 5g.

[0091] S340, when the ink weight reaches a second preset weight, second control information is generated; wherein the second control information is used to control the ink filling device to stop filling ink into the storage containing space, and to isolate the ink filling channel and the propylene containing space from each other.

[0092] It can be understood that the second preset weight is a target ink weight (such as 12g corresponding to 10ml) converted according to the design capacity (such as 10ml, 20ml) of the propylene marker and the propylene pigment density (about 1.2g / cm³), and the second preset weight is the qualified threshold of the ink filling amount. Because the propylene pigment is a suspension containing particles, its volume will change slightly due to factors such as temperature and stirring state (such as increased viscosity of the pigment at low temperature, higher mass under the same volume), and direct volume measurement by the ink filling device (such as 10ml) may cause actual ink mass deviation. By calculating the weight difference, regardless of the change of the propylene pigment state, the ink weight can truly reflect the total mass of the injected pigment (such as a target ink filling amount of 12g, as long as the weight difference reaches 12g, which ensures the accurate total amount of the pigment), which is more in line with the production needs of the propylene marker.

[0093] S400, after the execution of the second control information is completed, the air extraction device is controlled to connect the air extraction channel and the ink filling channel, extract the air in the storage containing space, and monitor the pressure data in real time.

[0094] It can be understood that the second control information execution completion represents that the ink injection device has stopped ink injection (the ink weight is up to standard), and the ink injection channel and the propylene containing space have completed isolation (the ink injection channel is isolated from the connecting channel). The control of the air extraction device to connect the air extraction channel and the ink injection channel can be to control the air extraction partition to open to make the air extraction channel and the ink injection channel communicate with each other. The way to extract the air in the storage containing space can be to control the air extraction drive to extract air at a preset air extraction rate, or to retrieve the corresponding air extraction rate in the preset database indexed by the specific model of the propylene marker, and then control the air extraction drive to extract air at the air extraction rate obtained after retrieval, but is not limited thereto. The way to monitor the pressure data in real time can be to receive the air pressure data collected by the pressure collection element at a preset frequency, or to receive the data transmitted by the user, but is not limited thereto.

[0095] S500, obtaining quality information based on the pressure data; wherein the quality information reflects whether the quality of the propylene marker after ink injection is qualified.

[0096] It can be understood that the way to obtain quality information based on pressure data can be to calculate the pressure drop rate from the pressure data of the air extraction process, and then compare the pressure drop rate with a preset drop rate to obtain quality information, or to send the pressure data to the user and then receive the data transmitted by the user, but is not limited thereto. Obtaining quality information based on pressure data analyzes the pressure data during air extraction and pressure maintenance to determine whether the sealing of the storage part and the ink injection sealing part is up to standard, so as to avoid substandard markers with poor sealing or excessive air residue from flowing into the market.

[0097] In one possible implementation, please refer to Figure 6 , S500, obtaining quality information based on the pressure data, comprising: S510, when the monitored pressure data is less than a preset pressure, confirming the pressure data as pressure drop data, and confirming all the pressure drop data as pressure drop stage information; wherein each pressure drop data in the pressure drop stage information is sorted in ascending order of monitoring time.

[0098] It can be understood that the preset pressure can be -0.085MPa, -0.09MPa, or the corresponding pressure retrieved in the preset database indexed by the specific model of the propylene marker, but is not limited thereto. When the monitored pressure data is less than the preset pressure, the pressure data is confirmed as pressure drop data, which can exclude invalid data in the initial stage of air extraction (when the air extraction device is just started, the pressure data can still be at or close to normal pressure, and has not yet entered the effective stage of air extraction). Confirming all the pressure drop data as pressure drop stage information can provide a basis for subsequent steps.

[0099] S520, obtaining pressure reduction analysis information based on the pressure reduction stage information; wherein the pressure reduction analysis information reflects whether the quality of the propylene marker is qualified.

[0100] It can be understood that the manner of obtaining the pressure reduction analysis information based on the pressure reduction stage information can be calculating the pressure reduction rate (average pressure reduction rate) according to the pressure reduction stage information, and then obtaining the pressure reduction analysis information by judging whether the pressure reduction rate is within the preset pressure reduction rate range, or can be sending the pressure reduction stage information to the user and then receiving the data transmitted by the user, but is not limited thereto. Obtaining the pressure reduction analysis information based on the pressure reduction stage information can directly reflect the smoothness of the air exhaust in the storage space during air extraction. If there is an obvious gap (such as injection flaw, loose sealing of the ink injection sealing part) in the storage part or the ink injection sealing part, external air will continuously penetrate, resulting in abnormal pressure reduction data (such as slow or stagnant pressure reduction).

[0101] In one possible implementation, please refer to Figure 6 S520, obtaining pressure reduction analysis information based on the pressure reduction stage information, comprising: S521, obtaining the pressure reduction rate based on the pressure reduction stage information; wherein the pressure reduction rate reflects the pressure reduction rate in the storage space.

[0102] It can be understood that the pressure reduction rate reflects the average rate of the pressure reduction stage information, and reflects the pressure reduction amplitude in the storage space per unit time. The manner of obtaining the pressure reduction rate based on the pressure reduction stage information can be subtracting the first pressure reduction data in the pressure reduction stage information from the last pressure reduction data in the pressure reduction stage information, and then dividing the result by the time corresponding to the last pressure reduction data in the pressure reduction stage information minus the time corresponding to the first pressure reduction data in the pressure reduction stage information, and then taking the absolute value of the result, or can be sending the pressure reduction stage information to the user and then receiving the data transmitted by the user, but is not limited thereto.

[0103] For example, assuming that the last pressure reduction data in the pressure reduction stage information is -0.092 MPa, the corresponding time is 15 s, the first pressure reduction data in the pressure reduction stage information is -0.082 MPa, and the corresponding time is 5 s, then the pressure reduction rate = ((-0.092) - (-0.082)) / (15-5) = 0.001 MPa / s.

[0104] S522, if the pressure reduction rate is less than the minimum value in the preset pressure reduction rate range, or the pressure reduction rate is greater than the maximum value in the preset pressure reduction rate range, then obtaining the pressure reduction analysis information reflecting that the quality of the propylene marker is unqualified.

[0105] It can be understood that the preset pressure reduction rate range can be obtained by searching the preset database with the specific model of the propylene marker pen as the index, or can be received by the user transmitted data, etc., but not limited thereto. If the pressure reduction rate is lower than the lower limit of the range, it means that the pen barrel may have a sealing defect (external air continuously penetrates, offsetting the air extraction effect), and if the pressure reduction rate is higher than the upper limit of the range, it means that the storage part or the ink injection sealing part structure may be damaged (such as cracking to cause air to be discharged without obstruction).

[0106] S523, if the pressure reduction rate is within the preset pressure reduction rate range, the pressure reduction analysis information reflecting the quality of the propylene marker pen is obtained.

[0107] It can be understood that if the pressure reduction rate is within the preset pressure reduction rate range, it means that the storage part and the ink injection sealing part do not have obvious sealing defects.

[0108] S530, when the pressure data is equal to the preset pressure, a sub-control instruction is generated; wherein the sub-control instruction is used to control the air extraction device to stop extracting air in the storage containing space, and to separate the air extraction channel and the ink injection channel from each other.

[0109] It can be understood that when the pressure data is equal to the preset pressure, it means that the residual amount of air in the storage containing space reaches the expectation. By the sub-control instruction, the air extraction device is controlled to stop extracting air in the storage containing space, and the air extraction channel and the ink injection channel are separated from each other, avoiding the damage of the storage part or the ink injection sealing part caused by excessive negative pressure in the storage containing space, and providing environmental support for the subsequent steps.

[0110] S540, after the execution of the sub-control instruction is completed, the pressure data in the preset pressure maintaining time period is confirmed as pressure maintaining data, and all the pressure maintaining data is confirmed as pressure maintaining stage information.

[0111] It can be understood that the preset pressure maintaining time period can be 1s, 2s, or customized by the user, etc., but not limited thereto. The completion of the sub-control instruction means that the air extraction device has stopped air extraction and the air extraction channel and the ink injection channel have been separated from each other, ensuring the stability of the pressure maintaining environment. Confirming all the pressure maintaining data as the pressure maintaining stage information can provide a basis for the subsequent steps.

[0112] S550, based on the pressure maintaining stage information, pressure maintaining analysis information is obtained; wherein the pressure maintaining analysis information reflects whether the quality of the propylene marker pen is qualified.

[0113] It can be understood that the way of obtaining the pressure maintaining analysis information based on the pressure maintaining stage information can be calculating the average pressure maintaining rate (the rising amplitude of the pressure in the storage space per unit time) according to the data in the pressure maintaining stage information, comparing the average pressure maintaining rate with the preset rate to obtain the pressure maintaining analysis information, or transmitting the pressure maintaining stage information to the user and receiving the data transmitted by the user, but is not limited thereto. The pressure drop analysis can only identify the explicit defects (such as obvious gaps) of the rapid air leakage during the air extraction, while the pressure maintaining analysis information obtained based on the pressure maintaining stage information can discover the implicit defects hidden in the static negative pressure stage by analyzing the pressure change, verify the long-term sealing performance, and better match the actual use scene of the user.

[0114] In a possible implementation, referring to Figure 6 , S550, obtaining the pressure maintaining analysis information based on the pressure maintaining stage information, comprising: S551, obtaining the pressure maintaining rate based on the pressure maintaining stage information; wherein the pressure maintaining rate reflects the rising rate of the pressure in the storage space.

[0115] It can be understood that the way of obtaining the pressure maintaining rate based on the pressure maintaining stage information can be subtracting the value of the first pressure maintaining data in the pressure maintaining stage information from the value of the last pressure maintaining data in the pressure maintaining stage information, dividing the result by the value obtained by subtracting the time corresponding to the first pressure maintaining data in the pressure maintaining stage information from the time corresponding to the last pressure maintaining data in the pressure maintaining stage information, and taking the absolute value of the result, or transmitting the pressure maintaining stage information to the user and receiving the data transmitted by the user, but is not limited thereto. Obtaining the pressure maintaining rate based on the pressure maintaining stage information can provide a basis for the subsequent steps.

[0116] For example, assuming that the value of the first pressure maintaining data in the pressure maintaining stage information is -0.09 Mpa, the corresponding time is 0, the value of the last pressure maintaining data in the pressure maintaining stage information is -0.083 Mpa, and the corresponding time is 60, then the pressure maintaining rate = (-0.083-(-0.09)) / (60-0)≈0.000117 MPa / s.

[0117] S552, if the pressure maintaining rate is less than or equal to the preset pressure maintaining rate, obtaining the pressure maintaining analysis information reflecting that the quality of the propylene marker pen is qualified; if the pressure maintaining rate is greater than the preset pressure maintaining rate, obtaining the pressure maintaining analysis information reflecting that the quality of the propylene marker pen is unqualified.

[0118] It can be understood that if the pressure maintaining rate is less than or equal to the preset pressure maintaining rate, it means that the external air infiltration is extremely slow, and there is no implicit gap (such as a small crack in injection molding, implicit poor sealing of the ink injection sealing part) or defect in the storage part and / or the ink injection sealing part. If the pressure maintaining rate is greater than the preset pressure maintaining rate, it means that the storage part and / or the ink injection sealing part can have an implicit gap.

[0119] S560, if the pressure drop analysis information and the pressure maintaining analysis information both reflect that the quality of the propylene marker pen is qualified, quality information reflecting that the quality of the propylene marker pen is qualified is obtained; if the pressure drop analysis information and / or the pressure maintaining analysis information reflect that the quality of the propylene marker pen is unqualified, quality information reflecting that the quality of the propylene marker pen is unqualified is obtained.

[0120] It can be understood that, by respectively analyzing the pressure drop and the pressure maintaining through the pressure drop, the dynamic air extraction sealing property and the static pressure maintaining sealing property are verified, the screening blind area of the explicit sealing defect and the implicit sealing defect is covered, and the possibility of the unqualified propylene marker pen flowing into the market is reduced.

[0121] The propylene marker pen ink filling device provided by the embodiment of the present application can further include a control part which can be arranged on the mounting part and in communication connection with the fixed clamping device, the ink filling device and the air extraction device. The control part can include at least one processor, at least one memory and a computer program stored in the at least one memory and executable on the at least one processor. When the processor executes the computer program, the propylene marker pen ink filling device can realize the steps in any of the propylene marker pen ink filling method embodiments.

[0122] Exemplarily, the computer program can be divided into one or more modules / units which are stored in the memory and executed by the processor to complete the present application. The one or more modules / units can be a series of computer program instruction segments capable of completing a specific function, which are used to describe the execution process of the computer program in the control part.

[0123] The control part can be a control box, a programmable logic controller (PLC), a desktop computer, a notebook computer or the like. The control part can include, but is not limited to, a processor and a memory. Those skilled in the art can understand that the above-mentioned embodiments are only examples of the control part and do not constitute a limitation on the control part, and the control part can include more or fewer components, or combine certain components or different components, for example, can also include an input / output device, a network access device, a bus and the like.
