Description

Technical Field

[0001] This utility model relates to the field of diode technology, specifically to an electrostatic discharge protection device for diode production lines. Background Technology

[0002] The electrostatic discharge protection device on the diode production line is used to eliminate and prevent the generation of static electricity to protect electronic components such as diodes from electrostatic damage. It is the foundation of the electrostatic protection of the entire diode production line. All equipment and objects that may generate static electricity should be reliably grounded. At the same time, operators also need to be grounded by wearing grounding wristbands or other means to prevent human static electricity from damaging the diodes.

[0003] The electrostatic discharge protection device on the diode production line is generally a ring structure made of metal or high-strength plastic, which makes it convenient for users to hang it on keychains, bags and other items for easy carrying.

[0004] In factory workshops, electronic equipment assembly areas, and other places, a large number of fine particulate matter are present in the air. They constantly adhere to the metal surface. This dirt not only physically blocks the transmission path of static electricity, but also may breed bacteria and corrode metals in the long term, further deteriorating the conductivity. Once the metal part becomes less conductive due to oxidation or dirt, static electricity cannot be released in time. When it accumulates to a certain extent, it may damage sensitive electronic components, seriously affecting the safety of diode production operations and product quality.

[0005] Therefore, an electrostatic discharge protection device for diode production lines is proposed to address the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to provide an electrostatic discharge protection device for diode production lines, in order to solve the problem that once the metal parts become less conductive due to oxidation or dirt, static electricity cannot be released in time, and when it accumulates to a certain extent, it may damage sensitive electronic components, seriously affecting the safety of production operations and product quality.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0010] As a further optimization of this utility model, the auxiliary slide groove is provided in multiple ways, the vertical cross-section of the auxiliary slide groove is U-shaped, the auxiliary slide groove is distributed in a circular array with the vertical line of the electrostatic bar as the axis, and the auxiliary slide groove corresponds one-to-one with the limiting groove.

[0011] As a further optimization of this utility model, the limiting groove is located below the cleaning component, the vertical cross-section of the limiting groove is U-shaped, the limiting groove is distributed in a circular array with the vertical line of the electrostatic bar as the axis, and the limiting groove is staggered with the auxiliary sliding groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, through convenient operation, such as rotating and sliding the cleaning shell, the internal compression spring pushes the guide rod, making the cleaning brush closely adhere to the surface of the electrostatic bar.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Please see Figure 1-6 This utility model provides a technical solution:

[0030] The electrostatic discharge protection device on the diode production line includes a hook assembly 1. The lower end of the hook assembly 1 is fixedly connected to a housing 2. The inner side of the housing 2 is fixedly connected to an electrostatic discharge terminal 3. A cleaning component 4 is installed on the upper outer side of the electrostatic discharge terminal 3. The electrostatic discharge terminal 3 includes an electrostatic rod 31. The inner side of the electrostatic rod 31 has an inner sliding groove 32. The outer side of the electrostatic rod 31 has an auxiliary sliding groove 33. The upper outer side of the electrostatic rod 31 has a limiting groove 34. The cleaning component 4 includes a cleaning shell 41. The upper inner side of the cleaning shell 41 has an installation groove 42. The lower end of the cleaning shell 41 is fixedly connected to a limiting plate 43. The inner side of the cleaning shell 41 has an installation cavity 44. A compression spring 45 is fixedly connected to the inner side of the installation cavity 44. The other end of the compression spring 45 is fixedly connected to a guide rod 46. One end of the guide rod 46 has a threaded hole 47. The inner side of the threaded hole 47 is threaded with a threaded rod 48. The other end of the threaded rod 48 is fixedly connected to a cleaning brush 49.

[0031] As a further implementation of the above technical solution: one end of the cleaning brush 49 is set to be arc-shaped, and one side of the flat side of the cleaning brush 49 is closely attached to the end of the guide rod 46 with the threaded hole 47. The outer side of the guide rod 46 is slidably connected to the inner side of the mounting cavity 44. The appropriate arc-shaped design can closely fit the arc-shaped part of the lower end of the electrostatic rod 31, ensuring that the key discharge area of ​​the electrostatic rod 31 is thoroughly cleaned, removing oxide layers, dust and oil stains, restoring the conductivity of the electrostatic rod 31, and ensuring the working efficiency of the electrostatic discharge end 3.

[0032] As a further implementation of the above technical solution: the limiting groove 34 is set below the cleaning component 4. The vertical cross-section of the limiting groove 34 is U-shaped. The limiting groove 34 is distributed in a circular array with the vertical line of the electrostatic bar 31 as the axis. The limiting groove 34 and the auxiliary sliding groove 33 are staggered and cooperate with the limiting plate 43. In the daily non-cleaning state, it plays a precise positioning and fixing role for the cleaning component 4, ensuring that the cleaning brush 49 is always in the initial working position that is close to the surface of the electrostatic bar 31, ensuring that the electrostatic discharge function is not affected, and at the same time preventing the cleaning component 4 from being damaged by accidental shaking or displacement.

[0033] As a further implementation of the above technical solution: multiple limiting plates 43 and limiting grooves 34 are provided. One end of the limiting plate 43 has the same shape as the limiting groove 34. The lower end of the limiting plate 43 is engaged with the inner side of the limiting groove 34. The outer side of the limiting plate 43 is slidably connected to the inner side of the auxiliary slide groove 33. In different stages of the cleaning operation, the position and direction of movement of the cleaning shell 41 are precisely controlled by actions such as engaging and sliding, ensuring that the cleaning process is carried out in an orderly manner. This not only achieves convenient fixation of the cleaning component 4, but also meets the dynamic adjustment of cleaning needs.

[0034] As a further implementation of the above technical solution: the cleaning component 4 is set on the outer side of the upper end of the inner slide groove 32. The inner slide groove 32 is set in a ring shape. The outer side of the inner slide groove 32 is slidably connected to the inner side of the cleaning shell 41. The cleaning shell 41 is ring-shaped. The ring design allows the cleaning component 4 to cover the surface of the electrostatic rod 31 in all directions without leaving any cleaning dead corners.

[0035] As a further implementation of the above technical solution: multiple auxiliary slides 33 are provided. The vertical cross-section of the auxiliary slides 33 is U-shaped. The auxiliary slides 33 are arranged in a circular array with the vertical line of the electrostatic bar 31 as the axis. The auxiliary slides 33 correspond one-to-one with the limiting grooves 34, which facilitates the multi-angle position adjustment of the cleaning shell 41 on the electrostatic bar 31 to adapt to the cleaning needs of different parts. It also enhances the controllability and flexibility of the cleaning process and improves cleaning efficiency.

[0036] As a further implementation of the above technical solution: the inner side of the mounting groove 42 is rotatably connected to the outer side of the upper end of the electrostatic rod 31. Multiple compression springs 45 and guide rods 46 are provided. The compression springs 45 and guide rods 46 are arranged in a circular array with the center line of the cleaning shell 41 as the axis. The compression springs 45 and guide rods 46 correspond one to one. During the cleaning process, an elastic force is always applied towards the surface of the electrostatic rod 31, which causes the guide rods 46 to drive the cleaning brush 49 to fit tightly against the electrostatic rod 31. No matter how the cleaning shell 41 moves or rotates, it can ensure that the cleaning brush 49 continuously and effectively wipes the electrostatic rod 31, removes dirt, and maintains the good conductivity of the electrostatic rod 31.

[0037] Workflow: The electrostatic protection device is attached to a keychain or other portable item via the hook assembly 1 and carried with you. When you need to touch a diode or related equipment that may pose an electrostatic risk, hold the device in hand to prepare for electrostatic discharge. The static electricity carried by the human body is conducted through the outer shell 2 to the electrostatic discharge rod 31 at the electrostatic discharge end 3. Using the tip discharge principle of the electrostatic rod 31, the static electricity is safely released into the air, avoiding damage to the diode.

[0038] The cleaning shell 41 is fitted onto the outer side of the upper end of the electrostatic bar 31 through the mounting groove 42. The lower end of the limiting plate 43 is engaged with the inner side of the limiting groove 34, and the outer side of the limiting plate 43 is slidably connected to the inner side of the auxiliary slide groove 33. At this time, the cleaning brush 49, under the action of the compression spring 45, has one end tightly attached to the surface of the electrostatic bar 31. When it is necessary to clean the outer side of the electrostatic bar 31, first slide the cleaning shell 41 upward to disengage the limiting plate 43 at the bottom of the cleaning shell 41 from the inner side of the limiting groove 34. Then rotate the cleaning shell 41. After rotating it a certain angle, slide the cleaning shell 41 downward to align the limiting plate 43 with the auxiliary slide groove 33, and then slide it downward along the auxiliary slide groove 33. This can effectively clean the surface of the electrostatic bar 31. During the sliding process, the compression spring 45 pushes the guide rod 46, so that the cleaning brush 49 always adheres to the surface of the electrostatic bar 31, and the cleaning brush 49 continuously wipes the surface of the electrostatic bar 31. The cleaning brush 49 removes oxide layers, dust, and oil stains. Simultaneously, the guide rod 46 slides within the mounting cavity 44, ensuring smooth movement of the cleaning brush 49. This effectively cleans the lower arc-shaped portion of the electrostatic discharge end 3. When adjusting to other angles, the cleaning shell 41 is moved upwards above the auxiliary slide groove 33, disengaging the limiting plate 43 from the auxiliary slide groove 33. Then, it is rotated to the desired angle, aligning the limiting plate 43 with the auxiliary slide groove 33, and then sliding downwards along the auxiliary slide groove 33 for cleaning. After cleaning, the cleaning shell 41 is moved upwards above the auxiliary slide groove 33, disengaging the limiting plate 43 from the auxiliary slide groove 33, and then rotated again, aligning the limiting plate 43 with the limiting groove 34 and sliding downwards to secure the cleaning assembly 4 for future use. The threaded rod 48 and threaded hole 47 allow for replacement of the cleaning brush 49, improving cleaning quality.
