Description

Technical Field

[0001] This utility model belongs to the field of ESD protection technology, specifically relating to an ESD protection device for a grain cutting equipment. Background Technology

[0002] During the die cutting process, static electricity can easily be generated on the surface of the die, cutting tools, and equipment due to friction and contact. When the accumulated static voltage reaches a certain level, a discharge phenomenon will occur, which can damage the product and cause it to fail. The frequency of this failure is unpredictable, and failed products are often not screened out during the production process, but are only discovered during the final testing after plastic sealing or even during use, which has a significant impact on product quality. Existing die cutting equipment does not take effective static electricity removal measures at the deionized water nozzle, resulting in excessively high accumulated static voltage, which can easily cause electrostatic discharge problems. The deionized water nozzle comes into contact with the die during the cutting process. If static electricity accumulates at the nozzle, it can easily be transferred to the die, causing die damage. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide an ESD protection device for a grain cutting equipment, thereby solving the problems mentioned in the background art.

[0004] This utility model provides an ESD protection device for a die cutting equipment, including a cutting platform, a frame connected to the cutting platform and used to support the die cutting equipment, and a deionized water spray pipe mounted on the cutting platform via a mounting plate. It also includes a ground wire attached to the deionized water spray pipe and a connector for connecting the ground wire to the grounding system of the equipment. The ground wire is tightly connected to the deionized water spray pipe through the connector and connected to the grounding system of the equipment to conduct the static electricity accumulated at the nozzle into the grounding system of the equipment, thereby realizing the release and elimination of static electricity.

[0005] Preferably, an electrostatic monitor is installed at the nozzle of the deionized water spray pipe to monitor the electrostatic potential changes at the nozzle of the deionized water spray pipe in real time.

[0006] Preferably, it also includes a controller and an alarm component. The signal output terminal of the electrostatic monitor is connected to the signal input terminal of the controller to provide the controller with an electrostatic signal at the nozzle of the deionized water spray pipe. The signal output terminal of the controller is used to output a control signal, which is used to control the operation of the alarm component.

[0007] Preferably, the warning component includes an audible alarm and / or a visual warning light.

[0008] Preferably, the connector is a conductive and fastening element such as a fixing screw or a conductive clamp.

[0009] Preferably, a corrugated pipe is installed at the nozzle of the deionized water spray pipe, and an electric telescopic rod for adjusting the spray angle of the corrugated pipe is provided on the mounting plate.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0018] This utility model discloses an existing ESD protection device for a die cutting machine, which mainly includes a cutting platform 1, a frame 3 connected to the cutting platform 1 and used to support the die cutting machine, and a deionized water spray pipe 5 mounted on the cutting platform 1 via a mounting plate 4. It also includes a transmission system for driving the cutting tools such as cutting cutters or laser heads to move, and a movement mechanism for determining the position of the cutting tools on the workpiece, typically including X-axis, Y-axis, and Z-axis movement mechanisms. According to the cutting requirements, parameters such as cutting speed, depth, and cutting path are adjusted. The wafer is placed on the worktable of the cutting machine and precisely positioned to ensure the accuracy of the cutting. Special clamps or adhesives are used to fix the wafer on the cutting disc to prevent displacement or collision during the cutting process. After confirming that all settings are correct, the cutting machine is started and the cutting operation begins according to the preset parameters. During the cutting process, deionized water (ultrapure water) is sprayed from the deionized water spray pipe 5. Deionized water can remove surface contaminants, improve cutting accuracy, and protect wafer devices. The above is an introduction to an existing ESD protection device for a die cutting machine.

[0019] As can be seen from the above, the existing ESD protection device of a die cutting equipment has the following defects when in use: the existing die cutting equipment 2 does not take effective electrostatic removal measures at the deionized water nozzle, resulting in excessively high static voltage accumulation, which can easily cause electrostatic damage. The deionized water nozzle comes into contact with the die during the cutting process. If static electricity accumulates at the nozzle, it can easily be transferred to the die, causing die damage. Based on the above problems, the present invention adopts the following improvement method to solve them.

[0020] like Figure 1-5 As shown, an ESD protection device for a die cutting equipment includes a cutting platform 1, a frame 3 connected to the cutting platform 1 and used to support the die cutting equipment, and a deionized water spray pipe 5 mounted on the cutting platform 1 via a mounting plate 4. It also includes a ground wire 6 attached to the deionized water spray pipe 5 and a connector 7 for connecting the ground wire 6 to the equipment's grounding system. The ground wire 6 is tightly connected to the deionized water spray pipe 5 via the connector 7 and connected to the equipment's grounding system to conduct static electricity accumulated at the nozzle into the equipment's grounding system, thereby releasing and eliminating static electricity. Compared with existing technologies, the new grounding device can effectively reduce connection resistance, thereby conducting away accumulated charge and significantly reducing accumulated voltage pressure, thus protecting the die from electrostatic discharge.

[0021] Furthermore, such as Figure 1-4As shown, an electrostatic monitor 8 is installed at the nozzle of the deionized water spray pipe 5. The electrostatic monitor 8 can be an electrostatic sensor, integrating a high-sensitivity electrostatic sensor at the deionized water nozzle for real-time monitoring of electrostatic accumulation. Alternatively, it can be replaced by an electrostatic voltmeter, electrostatic field meter, or other equipment. The electrostatic voltmeter is aligned with the deionized water nozzle to measure the electrostatic potential at the nozzle. The electrostatic field meter assesses the electrostatic accumulation by measuring the electrostatic field strength near the nozzle. The installation of the electrostatic monitor 8 allows operators to monitor the changes in electrostatic potential at the nozzle of the deionized water spray pipe 5 in real time, thereby promptly identifying and addressing potential electrostatic problems. This real-time monitoring function enhances the preventative and responsive nature of the device, helping to further reduce the impact of electrostatics on the grains.

[0022] Furthermore, such as Figure 1 As shown, it also includes a controller 9 and an alarm component 10. The signal output terminal of the electrostatic monitor 8 is connected to the signal input terminal of the controller 9, and is used to provide the controller 9 with an electrostatic signal at the nozzle of the deionized water spray pipe 5. The signal output terminal of the controller 9 is used to output a control signal, which is used to control the operation of the alarm component 10. When the electrostatic monitor 8 detects that the electrostatic potential at the nozzle of the deionized water spray pipe 5 exceeds a preset threshold, it can automatically trigger an alarm to remind the operator to pay attention and take corresponding measures, thereby realizing the automatic alarm function for electrostatic abnormalities and ensuring that the operator can understand and deal with electrostatic problems in a timely manner.

[0023] Furthermore, the warning component 10 includes an audible alarm and / or a visual warning light. The use of the audible alarm and / or visual warning light makes the warning information more intuitive and easier to notice. This helps ensure that operators can notice the static electricity abnormality in a timely manner and take corresponding measures. It provides multiple forms of warning information and enhances the warning effect and reliability of the device.

[0024] Furthermore, such as Figure 1-5 As shown, the connector 7 is a conductive and secure component such as a fixing screw or conductive clip. This connector 7 can ensure the firmness between the ground lead 6 and the deionized water spray pipe 5, which helps to prevent static leakage caused by loose connection. In practical applications, the ground lead 6 can be made of materials with higher conductivity, such as silver-plated copper or gold-plated copper, to reduce resistance and improve static discharge efficiency. In addition, the number of ground leads 6 can be appropriately increased according to the size and shape of the deionized water spray pipe 5 to ensure that static electricity can be conducted into the grounding system more evenly and quickly.

[0025] Furthermore, such as Figure 2As shown, a corrugated pipe 11 is installed at the nozzle of the deionized water spray pipe 5. An electric telescopic rod 12 for adjusting the spray angle of the corrugated pipe 11 is provided on the mounting plate 4. By adjusting the extension length of the electric telescopic rod 12, the spray direction and angle of the corrugated pipe 11 can be precisely controlled to adapt to the needs of different grain cutting, while ensuring that the deionized water can uniformly and effectively cover the grain surface, further improving the static elimination effect. The electric telescopic rod 12 can be installed above the corrugated pipe 11 to realize the axial adjustment of the corrugated pipe 11, or it can be installed on the side of the corrugated pipe 11 near the mounting plate 4 to realize the lateral adjustment of the corrugated pipe 11. In use, a position sensor can also be integrated on the corrugated pipe 11 or the electric telescopic rod 12 and connected to the controller 9 to provide real-time feedback on the spray angle and position information so that the controller 9 can perform more precise control.
