Description

Technical Field

[0001] This utility model belongs to the field of workbench technology, and in particular relates to an anti-static workbench structure. Background Technology

[0002] Electrostatic discharge (ESD) is a serious concern when dealing with electronic products. Static electricity not only threatens electronic equipment but can also impact employee safety and business profitability. Whether in petrochemical plants or other industries, the primary measure to prevent the effects of static electricity is ensuring the implementation of anti-static grounding requirements.

[0003] The existing method of preventing static electricity on workbenches involves connecting the workbench to a common grounding point via a wire, thus conducting static electricity from the workbench into the ground. However, due to the length of the wire and its haphazard placement, the wire is easily stepped on or squeezed by equipment, tools, or personnel, leading to loosening or breakage of the connections. To solve these problems, it is necessary to design an anti-static workbench structure. Utility Model Content

[0004] This invention provides an anti-static workbench structure to solve the aforementioned problems in the prior art.

[0005] This utility model is implemented as follows: an anti-static workbench structure includes a workbench, with support legs fixedly installed at the four corners of the bottom of the workbench. Two spaced conductors are fixedly installed at the bottom of the workbench, and a rotating shaft is rotatably installed between the two conductors. The rotating shaft is provided with a spline, and a reel is slidably installed on the rotating shaft. The reel has a spline groove, and the rotating shaft passes through the reel. The reel and the rotating shaft are splinedly connected, and the reel and the rotating shaft are conductive.

[0006] A wire is fixedly connected inside the reel. The workbench, conductor, shaft, reel, and wire form a current conduction path. It also includes a common grounding device. The other end of the wire is electrically connected to the common grounding device.

[0007] As a preferred embodiment, an anti-static mat is placed on top of the workbench.

[0008] As a preferred embodiment, the common grounding device is a copper busbar.

[0009] As a preferred embodiment, the system further includes two spaced-apart support plates, which are fixedly connected to the support legs. A guide rod is fixedly installed between the two support plates, and a guide wheel is slidably installed on the guide rod. The guide rod passes through the guide wheel, and the wire passes through the guide wheel and is guided by the guide wheel.

[0010] As a preferred embodiment, an ion fan is fixedly installed at one end of the top of the workbench.

[0011] As a preferred embodiment, the ion fan is fixedly installed with a channel that communicates with the air outlet of the ion fan. The channel has multiple equidistantly distributed air outlets with curved sides. A connecting shaft is rotatably installed inside each air outlet, and the end of the connecting shaft is rotatably installed on the channel. Each air outlet is provided with a sealing element, which is fixedly installed on the connecting shaft. The sealing element is a columnar anti-tipping element that blocks the air outlet. An exhaust port is provided on the sealing element, and an elastic sheet is fixedly connected between the sealing element and the channel.

[0012] As a preferred embodiment, friction wheels are fixedly installed on the outer ends of the connecting shafts, a linear motor is fixedly installed on the outside of the channel, and a friction strip is fixedly installed on the movable seat of the linear motor. The friction strip contacts the friction wheels and is transmitted through friction.

[0013] Compared with related technologies, the antistatic workbench structure provided by this utility model has the following beneficial effects:

[0014] 1. The rotating shaft drives the reel to rotate, which winds up wires that are too long and not needed, thus preventing the wires from being placed randomly and reducing safety hazards; the guide wheels guide the wires, making them follow a predetermined path and preventing them from being placed haphazardly in the working environment.

[0015] 2. A linear motor drives the friction strip to move back and forth. The friction between the friction strip and the friction wheel causes the friction wheel to rotate, connecting the exhaust port with the inside of the channel to achieve the discharge of ion air. When the friction strip separates from the friction wheel, the exhaust port is blocked, thus allowing multiple exhaust ports to discharge air sequentially and circulate. This allows for targeted elimination of static electricity at different locations on the workbench, and it also saves on the amount of ion air used compared to fixed exhaust ports.

Detailed Implementation

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] A preferred embodiment of the anti-static workbench structure provided by this utility model is, for example... Figures 1 to 8 As shown:

[0028] An anti-static workbench structure includes a workbench 1, with support legs 7 fixedly installed at each of the four corners of the bottom of the workbench 1. Two spaced conductors 2 are fixedly installed at the bottom of the workbench 1, and a rotating shaft 3 is rotatably mounted between the two conductors 2. The rotating shaft 3 has a spline on it, and a reel 4 is slidably mounted on the rotating shaft 3. The reel 4 has a spline groove, and the rotating shaft 3 passes through the reel 4. The reel 4 and the rotating shaft 3 are splined. The reel 4 and the rotating shaft 3 are conductive. A wire 5 is fixedly connected inside the reel 4. The workbench 1, conductors 2, rotating shaft 3, reel 4, and wire 5 form a current conduction path. The structure also includes a common grounding device 6, with the other end of the wire 5 electrically connected to the common grounding device 6. The common grounding device 6 is a copper busbar.

[0029] In this anti-static workbench structure, the workbench 1, conductor 2, rotating shaft 3, reel 4, and wire 5 form a current conduction path. When static electricity is generated on the workbench 1, it can be conducted along this path. The static electricity is then ultimately conducted to the ground through the common grounding device 6, thereby effectively eliminating static electricity on the workbench.

[0030] By rotating the shaft 3, the reel 4 is driven to rotate, and the reel 4 winds up the wire 5 that is too long and not needed, thereby avoiding the random placement of the wire 5 and reducing safety hazards.

[0031] An anti-static mat 22 is placed on top of the workbench 1. The anti-static mat 22 has good conductivity. When operations are performed on the workbench 1, such as placing or moving items with static electricity, or when personnel carry static electricity and come into contact with the mat, the mat can quickly conduct away the static electricity accumulated on the surface of the workbench 1 or on the items or personnel.

[0032] It also includes two spaced-apart support plates 8, which are fixedly connected to the support legs 7. A guide rod 9 is fixedly installed between the two support plates 8, and a guide wheel 10 is slidably installed on the guide rod 9. The guide rod 9 passes through the guide wheel 10, and the wire 5 passes through the guide wheel 10 and is guided by the guide wheel 10. A servo motor 21 is fixedly installed on the support leg 7, and the output shaft of the servo motor 21 is fixedly connected to the rotating shaft 3.

[0033] In this embodiment, the guide wheel 10 guides the conductor 5, ensuring it follows a predetermined path and preventing it from being placed haphazardly in the work environment. This not only reduces the likelihood of the conductor 5 being stepped on or squeezed by equipment, tools, or personnel, and lowers the risk of loose or broken joints, but also makes the work area neater and more organized, facilitating personnel operation and equipment maintenance. Since the reel 4 can slide along the shaft 3, and the guide wheel 10 can slide along the guide rod 9, the position of the conductor 5 can be flexibly adjusted according to the location of the common grounding device 6, improving the applicability of the grounding structure.

[0034] The servo motor 21 can precisely control the rotation speed and direction of the shaft 3. When it is necessary to reel in the wire 5, the servo motor 21 drives the shaft 3 to rotate according to the set direction and speed. The shaft 3 drives the reel 4 to rotate via a spline connection, thereby winding the wire 5 onto the reel 4. When it is necessary to unwind the wire 5, the servo motor 21 rotates in the opposite direction, driving the shaft 3 and the reel 4 to rotate in opposite directions, so that the wire 5 is unwound from the reel 4. Through the automatic control of the servo motor 21, the automatic winding and unwinding of the wire 5 is realized, improving the convenience and efficiency of operation, avoiding the inaccuracies and tediousness that may be caused by manual winding and unwinding of the wire, and flexibly adjusting the length of the wire according to actual work needs.

[0035] In a further preferred embodiment of this utility model:

[0036] An ion fan 11 is fixedly installed at one end of the top of the workbench 1. A channel 12 is fixedly installed on the ion fan 11, and the channel 12 is connected to the air outlet of the ion fan 11. Multiple air outlets 13 are equidistantly distributed on the channel 12. The two sides of the air outlets 13 are curved. A connecting shaft 14 is rotatably installed inside the air outlets 13. The end of the connecting shaft 14 is rotatably installed on the channel 12. Each air outlet 13 is provided with a seal 15, which is fixedly installed on the connecting shaft 14. The seal 15 is a columnar anti-tipping seal that blocks the air outlets 13. An exhaust port 16 is opened on the seal 15. An elastic sheet 17 is fixedly connected between the seal 15 and the channel 12.

[0037] Friction wheels 18 are fixedly installed on the outer end of the connecting shaft 14. A linear motor 19 is fixedly installed on the outside of the channel 12. A friction strip 20 is fixedly installed on the movable seat of the linear motor 19. The friction strip 20 contacts the friction wheel 18 and is transmitted through friction.

[0038] In this embodiment, the ion fan 11 is a device capable of generating a large number of positive and negative ions. When the ion fan 11 is turned on, it ionizes the air, generating a large number of positive and negative ions. The environment around the workbench 1 and the items and personnel operating on the workbench 1 may carry static electricity. When these charged objects approach the ion stream blown out by the ion fan 11, the positive ions neutralize the negative charge on the surface of the object, and the negative ions neutralize the positive charge on the surface of the object, thereby achieving the purpose of quickly neutralizing static electricity, effectively eliminating static electricity in the workbench 1 area, and preventing static electricity from damaging sensitive electronic components.

[0039] Multiple air outlets 13 are initially sealed. When the ion fan 11 is not started, the sealing element 15 tightly seals the air outlets 13 under the action of the elastic sheet 17 to prevent external dust, debris and other objects from entering the interior of the channel 12.

[0040] When it is necessary to open the air outlet 13 to discharge ionized air, the linear motor 19 is activated. The movable seat of the linear motor 19 drives the friction strip 20 to move. The friction between the friction strip 20 and the friction wheel 18 causes the friction wheel 18 to rotate. The friction wheel 18 drives the connecting shaft 14 to rotate, which in turn causes the seal 15 fixed on the connecting shaft 14 to rotate. The elastic plate 17 deforms, allowing the exhaust port 16 to connect with the inside of the channel 12, thus realizing the discharge of ionized air. At the same time, the friction strip 20 intermittently contacts multiple friction wheels 18. When the friction strip 20 separates from the friction wheels 18, the elastic plate 17 drives the seal 15 to reset, and the air outlet 13 is blocked again. The linear motor 19 drives the friction strip 20 to move to one end and then moves in the opposite direction. The linear motor 19 drives the friction strip 20 to move back and forth. Therefore, multiple air outlets 13 discharge air sequentially and circulate, which can target different positions of the workbench 1 to eliminate static electricity. Compared with air outlets in fixed positions, it also saves the amount of ionized air used.
