[0002] In the process of chip-on-film roll production, it is necessary to print solder-reject ink on the surface of the product tape to protect the product tape and its formed circuits. The existing automatic ink supply system is designed similarly to the principle of a medicine injector. The motor drives the gear to rotate under the action of a pulse, and the gear drives the guide rod to move. The guide rod squeezes the movable rubber plug in the rubber barrel, and the movable rubber plug squeezes the ink in the ink supply rubber barrel. The ink is delivered from the ink outlet of the rubber barrel to the screen through the ink outlet tube. The existing automatic ink supply system involves disposable consumables (movable rubber plug, rubber barrel, hose, silicone plug, threaded connecting piece), ink waste and manpower waste, and has a high cost of use. The ink needs to be assembled into the hose for a second time after stirring, which affects the product yield; the machine needs to be shut down to change the ink, which affects production efficiency.

The branch air pipes are respectively connected to the first pressure barrel and the second pressure barrel and pass through the top cover.

[0010] Furthermore,

[0011] The pressure control mechanism comprises a pressure relief valve and an electronic pressure gauge. The pressure relief valve penetrates through the top cover of the pressure container and is installed on it. The lower part of the pressure relief valve is also equipped with an electronic pressure gauge.

[0012] Furthermore,

[0013] A sealing ring is arranged between the pressure container top cover and the pressure container barrel.

[0014] Furthermore,

[0019] S2. Start the equipment, and the sleeve flow meter at the ink outlet on the equipment determines whether the ink outlet is discharging ink by the flow rate. If no ink is discharging, a prompt is issued and the ink tank is waited for manual replacement before turning to S3. If ink is discharging, turn to S3;

[0020] S3. The device starts printing and supplies ink;

[0021] S4. After printing starts, if the sleeve flow meter at the ink outlet on the device fails to identify the flow within two seconds, an empty pipe warning will be issued and the device will alarm;

DETAILED DESCRIPTION

[0032] The present invention will be further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited to these embodiments.

[0033] Example 1

[0034] See also Figures 1 to 3 As shown,

[0035] A novel chip-on-film tape solder resist printing glue supply system includes a pressure barrel 1, wherein the pressure barrel 1 includes a first pressure barrel 11 and a second pressure barrel 12. The first pressure barrel 11 and the second pressure barrel 12 are both provided with an ink tilting bracket 3 for tilting an ink tank 2 at their inner bottoms. The ink tank 2 is placed on the ink tilting bracket 3, and the ink tank 2 can be fixed by a clamp on the pressure barrel 1. A booster mechanism 4 penetrates through a pressure vessel top cover through an air pipe 40 for conveying clean and dry air into the ink tank 2. A conveying monitoring mechanism 5 penetrates through the first pressure barrel 11 and the second pressure barrel 12 top covers through an ink conveying pipeline into the ink in the ink tank 2. The pressure vessel top cover is also provided with a pressure control mechanism 6 penetrating through the top cover.

[0036] The system adopts a dual pressure barrel 1 design of a first pressure barrel 11 and a second pressure barrel 12. Both barrels are provided with tilting brackets to fix and tilt the ink tank 2, which are further stabilized by clamps. The system uses a booster mechanism 4 to deliver clean dry air to the ink tank 2 to adjust the pressure. At the same time, the delivery monitoring mechanism 5 can monitor the ink delivery. In addition, the top cover of the pressure vessel is also equipped with a pressure control mechanism 6 to ensure stable operation of the system. The system realizes an efficient and stable printing glue supply process with one barrel in use and one barrel in reserve through precise control of ink delivery and pressure control, as well as a dual pressure barrel 1 design.

[0037] Furthermore,

[0038] The delivery monitoring mechanism 5 includes an ink delivery main pipe 500, an ink delivery branch pipe 501, a sleeve flowmeter 51, a solenoid valve, and a throttle valve 52. The ink delivery main pipe 500 is connected to the ink delivery branch pipe 501. The sleeve flowmeter 51 and the throttle valve 52 are respectively arranged on the ink delivery main pipe 500. An ink control solenoid valve 53 is arranged on each ink delivery branch pipe 501. A quick release device 7 is installed on the ink delivery branch pipe 501 below the ink control solenoid valve 53. The ink delivery branch pipe 501 passes through the top covers of the first pressure barrel 11 and the second pressure barrel 12 and enters the ink in the ink tank 2.

[0039] The sleeve flowmeter 51 and the throttle valve 52 are arranged on the ink delivery main pipe 500, so that the flow of ink can be monitored in real time and precisely regulated. The sleeve flowmeter 51 can accurately measure the flow of ink and provide the system with real-time flow data, thereby ensuring that the supply of ink is stable and meets production requirements. The throttle valve 52 can adjust the flow of ink according to production requirements to achieve precise control of the ink.

[0040] An ink control solenoid valve 53 is provided on each ink delivery branch pipe 501, which can realize independent control of the first pressure barrel 11 and the second pressure barrel 12, and can select one of them to supply ink, forming a mode of one barrel in use and one barrel in standby.

[0041] Furthermore,

[0042] The boost mechanism 4 includes a main air pipe 400, a branch air pipe 401, an air filter 41, a boost control solenoid valve 42, and a manual valve 43. The main air pipe 400 is connected to the branch air pipe 401. Before all the connected branch air pipes 401, the main air pipe 400 is sequentially equipped with an air filter 41 and a manual valve 43. All the branch air pipes 401 are equipped with a boost control solenoid valve 42. The branch air pipes 401 are respectively connected to the first pressure barrel 11 and the second pressure barrel 12 and pass through the top cover.

[0043] The function of the air filter 41 is to filter out impurities and moisture in the air, to ensure that the air entering the ink tank 2 is clean and dry, and to avoid contamination of the ink;

[0044] The hand valve 43 is used to manually control the on and off of the compressed air, so as to quickly cut off the air source when necessary to ensure the safety of operation;

[0045] The branch air pipe 401 is separated from the main air pipe 400 and connected to the first pressure barrel 11 and the second pressure barrel 12 respectively. A boost control solenoid valve 42 is provided on the branch air pipe 401 to control the opening and closing of the branch air pipe 401, thereby realizing the compressed air supply of the double barrels, and can selectively boost the pressure to the first pressure barrel 11 or the second pressure barrel 12, and cooperate with the ink control solenoid valve 53 on the ink delivery branch pipe 501 of the corresponding pressure barrel 1 to boost the pressure of the pressure barrel 1, and use the pressure to make the ink enter the ink delivery branch pipe 501;

[0046] For example, when the first pressure barrel 11 is used, the pressure-boosting control solenoid valve 42 on the branch gas pipe 401 connected to the first pressure barrel 11 and the ink control solenoid valve 53 on the ink delivery branch pipe 501 connected to the first pressure barrel 11 need to be opened, and the pressure-boosting control solenoid valve 42 on the branch gas pipe 401 connected to the second pressure barrel 12 and the ink control solenoid valve 53 on the ink delivery branch pipe 501 connected to the second pressure barrel 12 need to be closed. When the ink in the first pressure barrel 11 is used up, the pressure-boosting control solenoid valve 42 and the ink control solenoid valve 53 related to the second pressure barrel 12 are opened, and the pressure-boosting control solenoid valve 42 and the ink control solenoid valve 53 related to the second pressure barrel 12 are closed, and then the ink tank 2 in the first pressure barrel 11 is replaced, so that one barrel is used and one barrel is spared, and there is no need to stop the equipment to add ink.

[0047] Furthermore,

[0048] The pressure control mechanism 6 includes a pressure relief valve 61 and an electronic pressure gauge 60 . The pressure relief valve 61 is respectively installed on the top cover of the first pressure barrel 11 and the second pressure barrel 12 . The electronic pressure gauge 60 is also installed on the lower part of the pressure relief valve 61 .

[0049] During the ink delivery process, if the pressure in the ink tank 2 exceeds the preset safety range, the pressure relief valve 61 can automatically open to release the excess pressure, thereby preventing equipment damage or safety accidents caused by excessive pressure, improving the stability of the system, and ensuring the safety of operators;

[0050] The electronic pressure gauge 60 can display the pressure value in the ink tank 2 in real time, so that the operator can intuitively understand the current pressure status of the system. The operator compares the pressure value displayed by the electronic pressure gauge 60 with the preset pressure range. The operator can adjust the system pressure in time to ensure that the ink delivery process is carried out within the preset pressure range.

[0051] Furthermore,

[0052] A sealing ring is provided between the top cover of the first pressure barrel 11 and the second pressure barrel 12 and the barrel body of the first pressure barrel 11 and the second pressure barrel 12 .

[0053] The sealing ring is arranged between the top cover of the pressure barrel 1 and the barrel body of the pressure barrel 1 to prevent the pressure barrel 1 from leaking.

[0054] Furthermore,

[0055] The ink delivery branch pipe 501 should reach the lowest position in the ink tank 2 .

[0056] The ink delivery branch pipe 501 reaching the lowest position in the ink tank 2 can ensure that the remaining amount of ink in the ink tank 2 is minimized.

[0057] Furthermore,

[0058] An operating method of a novel chip-on-film tape solder resist printing glue supply system according to any one of claims 1 to 6, characterized in that it comprises the following steps:

[0059] S1. Before starting the equipment, the staff needs to open the pressure barrel 1 of the equipment to see if there is ink in the ink tank 2 in the pressure barrel 1. If there is ink, turn to S2. If there is no ink, manually replace the ink tank 2 and then turn to S2;

[0060] S2. Start the device, the sleeve flowmeter 51 on the ink outlet of the device determines whether the ink outlet is out of ink by the flow rate. If the ink is not out, a prompt is issued and wait for manual replacement of the ink tank 2, then turn to S3, and the ink is turned to S3;

[0061] S3. The device starts printing and supplies ink;

[0062] S4. After printing starts, if the sleeve flow meter 51 at the ink outlet of the device does not recognize the flow within two seconds, an empty pipe warning will be issued and the device will alarm;

[0063] S5. If the equipment alarm reminder does not exceed ten minutes, the equipment stops printing and ink supply, waiting for manual replacement of ink tank 2; if the equipment alarm time exceeds ten minutes, it is confirmed that the production is over and the machine stops automatically;

[0064] S6. The operation ends when the personnel completes disassembly of the pipeline.

[0065] The specific operation process of the new COF tape solder rejection printing glue supply system is as follows:

[0066] Before starting the equipment, the staff first checks whether the ink tank 2 in the first pressure barrel 11 and the second pressure barrel 12 is filled with ink. If there is ink in the ink tank 2, continue to prepare to start the equipment; if there is no ink in the ink tank 2, manually replace the new ink tank 2. When replacing the ink tank 2, put the ink tank 2 into the pressure barrel 1, tilt it by tilting the bracket, and fix it with a clamp. Insert the ink delivery pipe into the ink tank 2 to the lowest position, and fix it with the quick release device 7, and connect the sleeve flow meter 51, throttle valve 52 and other equipment at the same time. Next, close the pressure relief valve 61 to ensure that the pressure barrel 1 is sealed and leak-free.

[0067] After starting the device, the sleeve flow meter 51 on the device starts to monitor the flow of the ink delivery pipe. If the flow is normal, it means that the ink outlet is normally discharging ink, and the device can start printing and supplying ink. If the flow is abnormal, that is, no ink is discharged, the device will issue a prompt and wait for manual replacement of the ink tank 2 before restarting the device.

[0068] During the printing process, the sleeve flow meter 51 continuously monitors the flow rate and issues an empty pipe warning if the flow rate is not recognized for two seconds, and the device will alarm. If the alarm does not exceed ten minutes, the device will stop printing and ink supply and wait for manual replacement of the ink tank 2; if the alarm time exceeds ten minutes, it is confirmed that the production is over and the device automatically stops.

[0069] At the end of production, personnel need to disassemble the pipeline. At this time, the quick-release device 7 plays a key role. By rotating to the open state, the caliber becomes larger, which is convenient for personnel to disassemble. After the disassembly is completed, the whole operation process ends.

[0070] In addition, the system also has the function of free switching between the two pressure barrels 1. When the first pressure barrel 11 is used, the corresponding

[0071] The boost control solenoid valve 42 on the branch gas pipe 401 and the ink control solenoid valve 53 on the ink delivery branch pipe 501 are opened, and the first pressure barrel 11 can supply glue normally; when it is necessary to switch to the second pressure barrel 12, it is only necessary to close the relevant solenoid valve of the first pressure barrel 11 and open the relevant solenoid valve of the second pressure barrel 12. This design realizes an efficient and stable printing glue supply process, ensuring the need of one barrel for use and one barrel for backup.

[0072] During operation, the electronic pressure gauge 60 monitors and displays the pressure in the pressure barrel 1 in real time, which is convenient for the staff to observe the pressure in the barrel. When the pressure in the pressure barrel 1 is about to exceed the preset pressure range, a linkage warning is issued. If the pressure exceeds the preset range, the pressure relief valve 61 will automatically open to release the excess pressure to ensure the safe and stable operation of the equipment. At the same time, the setting of the sealing ring also ensures the sealing of the pressure barrel 1 to prevent leakage.

[0073] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
