Description

Technical Field

[0001] This invention relates to a method and system for preventing deviation and static electricity in a V-shaped ceramic minute hand mechanism, belonging to the field of minute hand anti-static technology. Background Technology

[0002] In precision minute hand mechanisms, the minute hand needs to complete accurate axial movement and positioning at high speed and high frequency. For a long time, this field has mainly faced the problems of mechanical runout and static electricity accumulation.

[0003] As a slender moving part, the dial indicator bar is susceptible to radial yaw during movement due to assembly gaps, drive mechanism disturbances, and its own inertia. This yaw directly leads to a decrease in the positioning accuracy of the dial indicator tip. In extreme cases, the needle tip may scrape and collide with the surrounding guide groove or baffle. Traditional solutions, such as setting a rigid baffle on one side of the path, can limit the yaw amplitude, but cannot prevent the needle tip from contacting and colliding with the baffle at the extreme yaw position, thus causing wear, abnormal noise, and exacerbating static electricity accumulation due to friction. Furthermore, the continuous high-speed relative motion between the metal dial indicator block and the inner wall of the metal needle groove, and between the dial indicator bar and the guide components in the dial indicator mechanism, constitutes a typical frictional phenomenon. Friction pairs are highly susceptible to generating and accumulating static charges due to the triboelectric effect. The accumulation of these static charges can lead to a series of serious consequences. Electrostatic attraction can cause unexpected sticking and needle-carrying phenomena in the minute hand, where the needle tip is attracted to the baffle and groove wall, thereby disrupting the smoothness and timing of movement. On the other hand, the accumulated high-voltage static charge may generate instantaneous discharge sparks, which not only interfere with precision electronic systems, but the electromagnetic pulses and micro-force impacts generated can also affect the mechanical stability of the mechanism. Furthermore, the environmental dust attracted by static electricity can accelerate the wear of the mechanism. In the existing technology, although there have been attempts to use anti-static material coatings or simple grounding paths, it is often impossible to achieve stable and controllable charge dissipation throughout the entire movement.

[0004] More importantly, the two problems mentioned above do not exist in isolation, but form a vicious cycle of triboelectricity, electrostatic adsorption, motion stagnation, increased sway, and even more friction. Traditional solutions mostly view and solve these two problems in isolation, such as simply reinforcing the structure to resist sway or simply replacing materials to prevent static electricity, without designing a synergistic control mechanism at the system level that can simultaneously suppress mechanical sway and electrostatic accumulation. Summary of the Invention

[0005] This invention provides a method and system for preventing deviation and static electricity in a V-shaped ceramic dial indicator mechanism. Its main purpose is to simultaneously suppress mechanical sway and static electricity accumulation at the system level.

[0006] To achieve the above objectives, the present invention provides a method for preventing deviation and static electricity in a V-shaped ceramic dial indicator mechanism, comprising: Replace the metal needle block with a ceramic needle block, and fix the ceramic needle block vertically to the radial deflection guard plate in the needle groove; A V-shaped needle-blocking area is provided around the needle groove to divide the rise of the dispensing needle on the needle groove into a starting segment and a ending segment; When the sub-needle is in the starting segment, the radial deflection and static electricity accumulation of the sub-needle are simultaneously suppressed according to the ceramic sub-needle block, the radial deflection guard plate and the needle groove, so as to obtain the primary control result of anti-deflection and anti-static. When the sub-needle enters the final section, the contact tendency and residual charge of the sub-needle are simultaneously suppressed according to the ceramic sub-needle block, the V-shaped needle blocking area and the needle groove, so as to obtain the final anti-static control result. The anti-deviation and anti-static control result of the minute hand is determined by the primary control result of the anti-deviation and anti-static control and the final control result of the anti-static control.

[0007] Optionally, based on the ceramic dispensing needle block, the V-shaped needle-blocking area, and the needle groove, the contact tendency and residual charge of the dispensing needle are simultaneously suppressed to obtain the final antistatic control result, including: By utilizing the V-shaped guide surface of the V-shaped needle-stopping area, a non-contact gap is formed between the needle tip of the dispensing needle and the V-shaped needle-stopping area, thereby blocking the contact friction between the dispensing needle and the V-shaped needle-stopping area; While blocking the contact friction, the residual charge of the minute hand is suppressed, resulting in the final antistatic control.

[0008] Optionally, before suppressing residual charge on the dial needle to obtain the final antistatic control result, the method further includes: A variable-depth helical groove is provided on the end face of the cam that drives the minute hand; The depth of the variable-depth spiral groove varies monotonically along the rotation direction of the cam at the bottom of the minute hand. A conductive layer is embedded in the variable-depth spiral groove, and the conductive layer is connected to the grounding terminal. A carbon fiber brush assembly is disposed on the conductive layer; The carbon fiber brush assembly includes a root slider and brush filaments. The root slider is embedded in the conductive layer, and the brush filaments are in contact with the metal conductive area on the surface of the ceramic needle block.

[0009] Optionally, residual charge is suppressed on the dial indicator to obtain the final antistatic control result, including: When the minute hand is driven to make an axial lifting motion by the rotation of the cam at the bottom of the minute hand, the groove depth of the variable depth spiral groove changes by the rotation of the cam. The change in the groove depth pulls the root slider of the carbon fiber brush filament along the variable depth spiral groove; The movement of the root slider allows the brush bristles to continuously contact the metal conductive area on the surface of the ceramic needle block. The pressure exerted by the brush bristles on the conductive metal area varies monotonically with the groove depth by moving the root slider. When the brush bristles are in continuous contact with the metal conductive area and the clamping force on the metal conductive area increases, the residual charge adsorbed on the metal conductive area is transferred to the grounding terminal based on the reduced contact resistance between the brush bristles and the metal conductive area, so as to suppress the residual charge on the sub-hand and obtain the final anti-static control result.

[0010] Optionally, based on the reduced contact resistance between the brush bristles and the metal conductive region, the residual charge adsorbed in the metal conductive region is transferred to the grounding terminal, including: The residual charge adsorbed by the metal conductive region is transferred to the brush bristles based on the reduced contact resistance between the brush bristles and the metal conductive region. The residual charge on the bristles is transferred to the root slider; The residual charge on the root slider is transferred to the conductive layer; The residual charge on the conductive layer is transferred to the ground terminal.

[0011] Optionally, the metal dial indicator block can be replaced with a ceramic dial indicator block, including: Alumina ceramic rods are machined into ceramic needle blocks using CNC turning technology; Replace the metal needle block with the ceramic needle block; The ceramic needle block has a metal conductive area embedded on its surface.

[0012] Optionally, the ceramic needle block and the radial deflection guard plate are vertically fixed in the needle groove, including: The ceramic needle block and the radial sway guard plate are fixed parallel to and alternately perpendicular to the base of the needle groove; The width of the guide channel formed between the ceramic needle block and the radial sway guard plate is greater than the diameter of the needle rod. The needle rod moves axially in the guide channel. The radial sway guard plate is made of antistatic POM material.

[0013] Optionally, a V-shaped needle-stopping area is provided circumferentially in the needle groove, including: A circumferential V-shaped needle-stopping area is provided at the axial end of the needle groove.

[0014] Optionally, based on the ceramic dispensing needle block, the radial deflection guard plate, and the needle groove, the radial deflection and static electricity accumulation of the dispensing needle are simultaneously suppressed to obtain a primary control result of anti-deflection and anti-static properties, including: The ceramic needle block and the radial deflection guard plate form a bidirectional limiting structure to laterally limit the needle rod of the needle, thereby suppressing the radial deflection of the needle. While suppressing the radial deflection of the minute hand, the charge adsorption characteristics of the ceramic minute hand block are used to adsorb the static electricity accumulation generated by the axial movement of the minute hand in the guide channel, so as to simultaneously suppress the static electricity accumulation of the minute hand and obtain the primary control result of anti-deflection and anti-static.

[0015] To address the aforementioned problems, the present invention also provides a V-shaped ceramic dial indicator mechanism anti-deviation and anti-static control system, the system comprising: The guard plate fixing module is used to replace the metal needle block with a ceramic needle block and to fix the ceramic needle block and the radial deflection guard plate vertically in the needle groove. The lift segmentation module is used to set a V-shaped needle-blocking area in the circumference of the needle groove, dividing the lift of the dispensing needle in the needle groove into a starting segment and a final segment; The electrostatic suppression module is used to simultaneously suppress the radial deflection and electrostatic accumulation of the sub-needle when the sub-needle is in the starting segment, based on the ceramic sub-needle block, the radial deflection guard plate and the needle groove, to obtain the primary control result of anti-deflection and anti-static. The charge suppression module is used to simultaneously suppress the contact tendency and residual charge of the sub-needle when it enters the end section, based on the ceramic sub-needle block, the V-shaped needle blocking area and the needle groove, to obtain the final anti-static control result. The result determination module is used to determine the anti-deviation and anti-static control result of the minute hand based on the primary anti-deviation and anti-static control result and the final anti-static control result.

[0016] Compared to the problems described in the background art, the embodiments of the present invention eliminate metal-metal friction pairs at the source by replacing the metal needle block with a ceramic needle block. Utilizing the inherent high resistance, low coefficient of friction, and anti-static properties of ceramic materials, the main pathway for static charge generation due to contact friction is fundamentally eliminated. Furthermore, the embodiments of the present invention vertically fix the ceramic needle block and the radial deflection guard plate within the needle groove. The relative arrangement of the ceramic needle block and the radial deflection guard plate forms a bidirectional, stable, rigid limiting structure, providing an accurate axial guiding channel for the needle rod. From the initial stage, an anti-deviation trajectory is preset, and the contact surfaces of the ceramic and anti-static POM in the channel are both non-metallic materials, eliminating the possibility of metal friction generating static electricity. Furthermore, in this embodiment of the invention, a V-shaped needle-stopping area is set circumferentially in the needle groove. Based on the characteristic that the V-shaped needle-stopping area is located at the end of the rise and its symmetrical inclined surface can forcibly guide the soon-to-be-positioned needle tip to the center, eliminating radial residual deviation and ensuring that the needle tip finally stops on the theoretical center line. In addition, the inclined surface design of the V-shaped needle-stopping area allows a constant non-contact gap to be maintained between the needle tip and the baffle, which can prevent friction generation at the end. To prevent electric shock and avoid hard collisions, this embodiment of the invention further divides the rise of the minute hand on the needle groove into a starting segment and a final segment, so that the minute hand mechanism can sequentially perform limiting tasks and charge discharge tasks in different segments. Furthermore, this embodiment of the invention uses a bidirectional limiting structure to clamp the minute hand rod in the center of the guide channel, thus constraining radial sway. The ceramic minute hand block simultaneously adsorbs the static charge generated by axial movement, preventing charge accumulation. This achieves mechanical sway suppression and electrostatic suppression within the same time period. Furthermore, this embodiment of the invention uses a V-shaped guide surface to maintain a constant non-contact gap between the needle tip and the baffle, thus blocking contact friction in the final segment, preventing needle tip scratches and frictional static electricity. Simultaneously, residual charge is quickly discharged through the charge discharge circuit, achieving the purpose of suppressing residual charge. Furthermore, this embodiment of the invention uses a pre-set variable-depth spiral groove on the cam end face and embeds a conductive layer and brush filament assembly. When the cam rotates, the pressure of the brush filaments on the metal conductive area increases or decreases synchronously with the groove depth, allowing the contact resistance to gradually change, thereby gradually suppressing residual charge. This gradual suppression of residual charge is for stable discharge rather than instantaneous discharge. Therefore, the present invention can simultaneously suppress mechanical yaw and electrostatic accumulation at the system level. Attached Figure Description

[0018] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0019] This application provides a method for preventing deviation and static electricity in a V-shaped ceramic dial indicator mechanism. The executing entity of this method includes, but is not limited to, at least one electronic device that can be configured to execute the method provided in this application, such as a server or a terminal. In other words, the method can be executed by software or hardware installed on a terminal device or a server device. The server includes, but is not limited to, a single server, a server cluster, a cloud server, or a cloud server cluster.

[0020] Reference Figure 1 The diagram shown is a flowchart illustrating an anti-deviation and anti-static control method for a V-shaped ceramic dial indicator mechanism according to an embodiment of the present invention. In this embodiment, the anti-deviation and anti-static control method for the V-shaped ceramic dial indicator mechanism includes: S1. Replace the metal needle block with a ceramic needle block, and fix the ceramic needle block and the radial deflection guard plate vertically in the needle groove.

[0021] This invention replaces the metal needle block with a ceramic needle block, thereby eliminating the metal-metal friction pair at its source. By utilizing the inherent high resistance, low coefficient of friction, and antistatic properties of ceramic materials, the main pathway for static charge generation due to contact friction is fundamentally eliminated.

[0022] In one embodiment of the present invention, the replacement of the metal needle block with the ceramic needle block includes: machining an alumina ceramic rod into a ceramic needle block using CNC turning technology; replacing the metal needle block with the ceramic needle block; wherein, the surface of the ceramic needle block is embedded with a metal conductive area.

[0023] The CNC turning technology involves directly loading alumina ceramic rods into a lathe and machining a ceramic parting block with the same shape as the metal parting block and a metallization zone pre-reserved groove on the surface of the ceramic parting block in a single program pass. The metal conductive zone is a conductive layer embedded in the metallization zone pre-reserved groove, which is used to receive the charge adsorbed by the ceramic. The metal conductive zone includes, but is not limited to, thin silver foil and silver paste sintering layer.

[0024] Furthermore, in this embodiment of the invention, the ceramic needle block and the radial deflection guard plate are vertically fixed in the needle groove. By arranging the ceramic needle block and the radial deflection guard plate relative to each other, a bidirectional and stable rigid limiting structure is formed. This provides an accurate axial guide channel for the needle rod, and the anti-deflection trajectory is preset from the beginning stage. Moreover, the ceramic and anti-static POM contact surfaces of the channel are both non-metallic materials, eliminating the situation of metal friction generating static electricity.

[0025] In one embodiment of the present invention, the step of vertically fixing the ceramic needle block and the radial sway guard plate in the needle groove includes: vertically fixing the ceramic needle block and the radial sway guard plate parallel to each other and alternately on the base of the needle groove; wherein, the width of the guide channel formed between the ceramic needle block and the radial sway guard plate is greater than the diameter of the needle rod, the needle rod moves axially in the guide channel, and the radial sway guard plate is made of antistatic POM material.

[0026] The minute hand rod is a hollow metal tube extending from the tail end of the minute hand. It is used to insert the minute hand. During axial movement, the tail end of the minute hand rod contacts a cam and is pushed axially by the cam. The minute hand inserted in the minute hand rod will also move axially under the action of the rod. The antistatic POM material is both antistatic and elastic. When the axially moving minute hand deviates towards the antistatic POM material, the elasticity of the material will bounce it back. Furthermore, no static electricity is generated when the minute hand contacts the antistatic POM material. It should be noted that when the axially moving minute hand deviates towards the antistatic POM material, the needle is radially wobbling.

[0027] See Figure 2 The diagram shown is a schematic representation of the dispensing mechanism for implementing the anti-deviation and anti-static control method of the V-shaped ceramic dispensing mechanism according to an embodiment of the present invention. Figure 2In the diagram, 1 represents the guide channel for accommodating the dispensing needle, 2 represents the radial deflection guard plate, 3 represents the ceramic dispensing needle block, and 4 represents the needle-blocking area. Whether it's the traditional vertical needle-blocking area or the V-shaped needle-blocking area of ​​this design, it's essentially a baffle shape. 2 and 3 are parallel and alternately vertically fixed to the base of the needle groove. The dispensing needle mechanism mentioned here includes... Figure 2 The whole.

[0028] S2. A V-shaped needle-blocking area is provided in the circumference of the needle groove to divide the rise of the dispensing needle in the needle groove into a starting segment and a ending segment.

[0029] In this embodiment of the invention, a V-shaped needle-blocking area is provided circumferentially in the needle groove. Based on the characteristic that the V-shaped needle-blocking area is located at the end of the stroke and its symmetrical inclined surface can force the needle tip of the dispensing needle that is about to be in place to be guided to the center, the radial residual deviation is eliminated, ensuring that the needle tip finally stops on the theoretical center line. In addition, the inclined surface design of the V-shaped needle-blocking area allows a constant non-contact gap to be maintained between the needle tip and the baffle, which can block the end-stage triboelectricity and avoid hard collisions.

[0030] In one embodiment of the present invention, the step of setting a V-shaped needle-stopping area in the circumferential direction of the needle groove includes: setting a circumferential V-shaped needle-stopping area at the axial end of the needle groove.

[0031] See Figure 3 The diagram shown is a schematic representation of a vertical stop pin of a baffle plate, used in an embodiment of the present invention to implement the anti-deviation and anti-static control method for the V-shaped ceramic dispensing mechanism. Figure 3 In the diagram, the horizontal left-pointing arrow (pointed to by 5) indicates the axial direction of the minute hand within the guide channel. The starting point of the axial direction (the starting point of the horizontal left-pointing arrow (pointed to by 5) is the cam end face, and the ending point is the V-shaped needle stop area. The minute hand begins its ascent from the cam end face. When it rises to the V-shaped needle stop area, the V-shaped notch reserved in the V-shaped needle stop area allows the minute hand to pass through, thus ensuring that the minute hand does not contact the needle stop plate after its ascent.

[0032] See Figure 4 The diagram shown is a schematic representation of a V-shaped baffle pin used in an embodiment of the present invention to implement the anti-deviation and anti-static control method for the V-shaped ceramic dispensing mechanism. Figure 4 In the middle, 6 represents the V-shaped notch in the V-shaped needle-stopping area.

[0033] Furthermore, in this embodiment of the invention, the rise of the minute hand on the needle groove is divided into a starting segment and a final segment, so that the minute hand mechanism can sequentially perform the limiting task and the charge discharge task in different intervals.

[0034] S3. When the sub-needle is in the starting segment, the radial deflection and static electricity accumulation of the sub-needle are simultaneously suppressed according to the ceramic sub-needle block, the radial deflection guard plate and the needle groove, so as to obtain the primary control result of anti-deflection and anti-static.

[0035] In this embodiment of the invention, the dial indicator bar is clamped in the center of the guide channel by a bidirectional limiting structure, which restricts radial sway. At the same time, the ceramic dial indicator block adsorbs the static charge generated by axial movement, so that the charge no longer accumulates, thereby achieving mechanical sway suppression and electrostatic suppression in the same time period.

[0036] In one embodiment of the present invention, the step of simultaneously suppressing radial deflection and electrostatic accumulation of the sub-needle based on the ceramic sub-needle block, the radial deflection guard plate, and the needle groove to obtain a primary anti-deflection and anti-static control result includes: using the bidirectional limiting structure formed by the ceramic sub-needle block and the radial deflection guard plate to laterally limit the sub-needle rod of the sub-needle to suppress radial deflection of the sub-needle; while suppressing radial deflection of the sub-needle, using the charge adsorption characteristics of the ceramic sub-needle block to adsorb the electrostatic accumulation generated by the axial movement of the sub-needle in the guide channel to simultaneously suppress electrostatic accumulation of the sub-needle and obtain a primary anti-deflection and anti-static control result.

[0037] The charge adsorption characteristic refers to the ability of ceramic materials to capture and temporarily retain static charge. Although ceramics are materials with good insulation, their surface is not completely non-conductive. When a minute hand with residual static electricity approaches, the ceramic surface will adsorb the residual charge on the minute hand onto its own surface through electrostatic induction.

[0038] It should be noted that the radial sway guard plate mentioned above can bounce back the misaligned minute hand, and the ceramic minute hand block can also bounce back the misaligned minute hand. When the minute hand moves axially, both the radial sway guard plate and the ceramic minute hand block on both sides can play a role in suppressing radial sway. The lateral limiting treatment mentioned above is essentially the suppression of radial sway. The bidirectional limiting structure is essentially a structure that limits the sway of the minute hand on both sides.

[0039] S4. When the sub-needle enters the final section, the contact tendency and residual charge of the sub-needle are simultaneously suppressed according to the ceramic sub-needle block, the V-shaped needle blocking area and the needle groove, so as to obtain the final anti-static control result.

[0040] In this embodiment of the invention, a V-shaped guiding surface is used to maintain a constant non-contact gap between the needle tip and the baffle, thereby blocking the contact friction at the end and avoiding needle tip scratches and frictional static electricity. At the same time, residual charge is quickly discharged through a charge discharge circuit to achieve the purpose of suppressing residual charge.

[0041] It should be noted that the charge discharge circuit here is the circuit in which the ceramic adsorbs the charge, the metal conductive area receives the charge adsorbed by the ceramic, and finally transfers it to the ground terminal.

[0042] In one embodiment of the present invention, the step of simultaneously suppressing the contact tendency and residual charge of the dispensing needle based on the ceramic dispensing needle block, the V-shaped needle-blocking area, and the needle groove to obtain the final antistatic control result includes: using the V-shaped guiding surface of the V-shaped needle-blocking area to form a non-contact gap between the needle tip of the dispensing needle and the V-shaped needle-blocking area to block the contact friction between the dispensing needle and the V-shaped needle-blocking area; while blocking the contact friction, suppressing the residual charge of the dispensing needle to obtain the final antistatic control result.

[0043] The V-shaped guide surface is a sloping wall with a V-shaped notch. The two sides of the notch symmetrically taper inward. When the minute hand deviates to the two sides of the notch, the sloping surfaces on both sides gradually constrain the needle tip to the center of the notch.

[0044] Furthermore, in this embodiment of the invention, by pre-setting a variable-depth spiral groove on the end face of the cam and embedding a conductive layer and a brush assembly, the clamping force of the brush on the metal conductive area increases or decreases synchronously with the groove depth when the cam rotates, so that the contact resistance can gradually change accordingly, thereby gradually suppressing residual charge. Gradually suppressing residual charge is for smooth discharge rather than instantaneous discharge.

[0045] In another embodiment of the present invention, before suppressing residual charge on the minute hand to obtain the final anti-static control result, the method further includes: providing a variable-depth spiral groove on the end face of the cam that drives the minute hand; wherein the depth of the variable-depth spiral groove monotonically changes along the rotation direction of the cam at the bottom of the minute hand; embedding a conductive layer in the variable-depth spiral groove, the conductive layer being connected to a grounding terminal; and providing a carbon fiber brush assembly on the conductive layer; wherein the carbon fiber brush assembly includes a root slider and brush filaments, the root slider being embedded in the conductive layer, and the brush filaments maintaining contact with the metal conductive area on the surface of the ceramic minute hand block.

[0046] It should be noted that the cam drives the minute hand to lift. The cam end face is the disk surface of the cam disc. The root slider is used to slide on the outer ring of the upper end face of the variable depth spiral groove, and can slide to different depths. One side of the root slider is in contact with the conductive layer, and the other side is connected to the brush bristles. Simply put, the combination of the root slider and the brush bristles is similar to a brush. The brush brushes the metal conductive area and is backed by the conductive layer.

[0047] See Figure 5 The diagram shown is a schematic representation of a variable-depth spiral groove used in an embodiment of the present invention to implement the anti-deviation and anti-static control method for the V-shaped ceramic dispensing mechanism. Figure 5 In the middle, you can see that the bottom surface is horizontal, but the outer edge of the upper surface has different depths. An additional groove has been dug out on the outer edge of the upper surface. Here's an explanation: In... Figure 5 No grooves were observed; only a spiral of varying depth was present.

[0048] In another embodiment of the present invention, the suppression of residual charge on the minute hand to obtain the final anti-static control result includes: when the minute hand is driven to make axial lifting motion by the rotation of the cam at the bottom of the minute hand, the rotation of the cam causes the groove depth of the variable depth spiral groove to change; the change in groove depth pulls the root slider of the carbon fiber brush filament to move along the variable depth spiral groove; the movement of the root slider allows the brush filament to continuously contact the metal conductive area on the surface of the ceramic minute hand block; the movement of the root slider allows the clamping force of the brush filament on the metal conductive area to monotonically change with the groove depth; when the brush filament is continuously in contact with the metal conductive area and the clamping force on the metal conductive area increases, the residual charge adsorbed on the metal conductive area is transferred to the grounding terminal according to the reduced contact resistance between the brush filament and the metal conductive area, so as to suppress the residual charge on the minute hand and obtain the final anti-static control result.

[0049] It should be noted that when the minute hand is driven to make axial lifting motion by the rotation of the cam at the bottom of the minute hand, the cam itself is rotating. As the cam rotates, the variable-depth helical groove, located on the cam end face, also rotates. This rotates the grooves of different depths to the points of contact with the metal conductive area. When the groove rotates from a lower depth to a higher depth, the pressure exerted by the originally lower-depth groove on the metal conductive area is less, resulting in a higher resistance between the brush bristles and the metal conductive area. Only a small portion of the charge received by the ceramic from the metal conductive area is transferred to the subsequent grounding terminal. Meanwhile, the pressure from the lower depth groove on the metal conductive area increases as the groove rotates from a lower depth to a higher depth. The greater the pressure exerted by the deep groove on the conductive metal area, the lower the resistance between the brush bristles and the conductive metal area. A significant portion of the charge received by the conductive metal area from the ceramic is then transferred to the subsequent grounding terminal. Furthermore, it's important to clarify two points: First, in the initial stage of the motion sequence, the contact pressure is controlled by the lower depth of the groove. Second, the contact resistance between the brush bristles and the conductive metal area mainly depends on the number and total area of ​​the actual conductive microscopic contact points. The larger the number and total area of ​​the contact points, the more and wider the current path is provided, resulting in a lower contact resistance.

[0050] In another embodiment of the present invention, the step of transferring the residual charge adsorbed by the metal conductive region to the grounding terminal based on the reduced contact resistance between the brush bristles and the metal conductive region includes: transferring the residual charge adsorbed by the metal conductive region to the brush bristles based on the reduced contact resistance between the brush bristles and the metal conductive region; transferring the residual charge on the brush bristles to the root slider; transferring the residual charge on the root slider to the conductive layer; and transferring the residual charge on the conductive layer to the grounding terminal.

[0051] S5. Determine the anti-deviation and anti-static control result of the minute hand based on the primary anti-deviation and anti-static control result and the final anti-static control result.

[0052] It should be noted that after completing the anti-deviation and anti-static control of S1 to S4 above, the anti-deviation and anti-static control results can be determined. This anti-deviation and anti-static control result refers to the result of the minute hand being corrected and the charge being discharged.

[0053] like Figure 6 The diagram shown is a functional block diagram of the anti-deviation and anti-static control system for the V-shaped ceramic dispensing mechanism of this invention.

[0054] The V-shaped ceramic dial indicator anti-deviation and anti-static control system 600 of this invention can be installed in electronic devices. Depending on the functions implemented, the V-shaped ceramic dial indicator anti-deviation and anti-static control system includes a guard plate fixing module 601, a lift segmentation module 602, an electrostatic suppression module 603, a charge suppression module 604, and a result determination module 605. The module described in this invention can also be called a unit, referring to a series of computer program segments that can be executed by the processor of an electronic device and perform a fixed function, stored in the memory of the electronic device.

[0055] In this embodiment of the invention, the functions of each module / unit are as follows: The guard plate fixing module 601 is used to replace the metal needle block with a ceramic needle block and to fix the ceramic needle block and the radial deflection guard plate vertically in the needle groove. The lift segmentation module 602 is used to set a V-shaped needle blocking area in the circumference of the needle groove, dividing the lift of the dispensing needle in the needle groove into a starting segment and a ending segment. The electrostatic suppression module 603 is used to simultaneously suppress radial deflection and electrostatic accumulation of the sub-needle when the sub-needle is in the starting segment, based on the ceramic sub-needle block, the radial deflection guard plate and the needle groove, to obtain the primary control result of anti-deflection and anti-static. The charge suppression module 604 is used to simultaneously suppress the contact tendency and residual charge of the sub-needle when the sub-needle enters the end section, based on the ceramic sub-needle block, the V-shaped needle blocking area and the needle groove, to obtain the final anti-static control result. The result determination module 605 is used to determine the anti-deviation and anti-static control result of the minute hand based on the anti-deviation and anti-static primary control result and the anti-static final control result.
