Description
Technical field
The present invention system is about a kind of electrostatic testing apparatus; In more detail, be the electrostatic testing apparatus of representing connection status about a kind of.
Background technology
In electron trade, the static entrained for fear of user's health damages the electronic package that it contacted, major part all adopts and requires the user to dispose the electrostatic detection ring on health, and the mode static that health is entrained on electrostatic detection articulating ground is transmitted to the earth, to eliminate the injury that static may cause.Yet the electrostatic detection ring needs well to be connected the competence exertion function with the earth, therefore needs to measure to confirm the good connection of electrostatic detection ring, needs measure once sometimes in one day, needs measure repeatedly sometimes in one day.So, both waste man-hour, had risk again.
Generally speaking, before the user started working every day, whether ground connection was good to use instrument to measure the electrostatic detection ring earlier, that is, whether eliminate static really.Just start working in measuring the back user.Yet this kind method waste working time, each staff must just can start working after measuring, and waits for time that measures and the time that is measured several times so everyone has every day.In addition, the risk that exists the electrostatic detection ring to lose efficacy in the course of work, in case lost efficacy, then the entrained static of health will cause serious damage to electronic product, influences the quality of product.In sum, how to provide a kind of electrostatic testing apparatus that can eliminate static really and indicate user's electrostatic detection result really, still be worth industry to endeavour research.
Summary of the invention
The objective of the invention is to, a kind of electrostatic testing apparatus is provided.This electrostatic testing apparatus comprises an electrostatic detection ring, a sample circuit and a treatment circuit.This electrostatic detection ring is connected to a user and an earth terminal.This sample circuit is in order to one of this user sampling static signal of sampling.This treatment circuit is judged the connection status of this user, this electrostatic detection ring and this earth terminal according to this sampling static signal, and produces a result.
But the device of employing Auto-Sensing of the present invention replaces artificial the measurement.After adopting this device, do not need regular measurement, can save human cost.In addition, can also monitor the ground connection situation of the electrostatic detection ring of user's configuration at any time, eliminate the risk that the entrained static of user's health damages electronic package fully.In addition, the device cost of manufacture of utilizing the present invention to finish is low, easy to operate.Can produce onlinely, several electrostatic testing apparatus are being set at interval corresponding to each unit, the corresponding pick-up unit of electrostatic detection ring, each pick-up unit is independent fully, mutually disturbing effect not.
Behind the embodiment of consulting graphic and description subsequently, this technical field has knows that usually the knowledgeable just can understand other purpose of the present invention, and the present invention's technological means and enforcement aspect.

Embodiment
With reference to Fig. 1, one of the present invention embodiment, it is an electrostatic testing apparatus 1, comprises an electrostatic detection ring 11, a sample circuit 12, a treatment circuit 13, a green LED 14, a yellow light-emitting diode 15, a red light emitting diodes 16, loudspeaker 17, a switch (not illustrating) and an electrostatic detection ring jack (not illustrating).Treatment circuit 13 more comprises an amplifying circuit 131 and a comparator circuit 132.
When user's desire detects the static content that its health may have, can put on electrostatic detection ring 11, allow health be connected, and make electrostatic detection ring 11 be connected to an earth terminal with electrostatic detection ring 11.Then, open switch, to start electrostatic testing apparatus 1.On the other hand, sample circuit 12 also is connected with this electrostatic detection ring 11, in order to see through electrostatic detection ring 11 from user's health static signal 101 of sampling.
And 13 of the treatment circuits that sample circuit 12 electrically connects can be according to the connection status between sampling static signal 101 judgement this user, this electrostatic detection ring 11 and this earth terminal threes, and produce a result 103, wherein, the connection status between the result 103 expression threes.
In the present embodiment, because the value of sampling static signal 101 is minimum, difficult directly processing, so, the amplifying circuit 131 of treatment circuit 13 can amplify sampling static signal 101 to get a sampling related signal 102, wherein, the mode of amplification can be linear amplification or non-linear amplification, and the amplification mode of amplifying circuit 131 is not the scope that is used for limiting the present invention.Then, the comparator circuit 132 of treatment circuit 13 is relatively sampled related signal 102 and a reference signal to obtain result 103.Wherein, reference signal is stored in the comparator circuit 132, and visual actual state adjusts.Because sampling related signal 102 is handled so can be fit to comparator circuit 132, to produce result 103 for amplifying signal later.
The user can be according to the connection status between result 103 judgement user, this electrostatic detection ring 11 and this earth terminal threes, and in the present embodiment, by three light emitting diodes and an acoustical generator, for example loudspeaker are pointed out user's result 103.Particularly, green LED 14, yellow light-emitting diode 15, red light emitting diodes 16 and loudspeaker 17 can carry out the action of difference according to result 103 respectively, to inform the connection status of user's electrostatic detection ring 11.In the present embodiment, if this result 103 is not less than this default signal for this sampling related signal, represent that then this electrostatic detection ring is connected normally with this user, this moment, 14 of green LEDs can be shinny.If this result 103 for this sampling related signal less than this default signal, it is improper to represent that then this electrostatic detection ring is connected with this user, at this moment 16 of red light emitting diodes can be shinny, loudspeaker 17 also can sounding.Moreover improper if this result 103 is that electrostatic detection ring 11 is connected with earth terminal, then 15 of yellow light-emitting diodes can be shinny, connects improper state to indicate this.The user can do suitable processing according to the indication of green LED 14, yellow light-emitting diode 15, red light emitting diodes 16 and loudspeaker 17.After using electrostatic testing apparatus 1, the user can be connected to electrostatic detection ring jack.
Be stressed that at this above-mentioned green LED 14, yellow light-emitting diode 15, red light emitting diodes 16 and loudspeaker 17 can be present in alone in the electrostatic testing apparatus 1 separately.In other words, electrostatic testing apparatus 1 can only have 1 or its combination wherein of green LED 14, yellow light-emitting diode 15, red light emitting diodes 16 and loudspeaker 17, can reach purpose.
In addition, above-mentioned green LED 14, yellow light-emitting diode 15, red light emitting diodes 16 are replaceable is light emitting diode or other any device that can be luminous of other color.But 17 on loudspeaker are replaceable to be the device of other sounding.
In sum, the present invention's electrostatic testing apparatus utilizes sample circuit and treatment circuit sampling and handles relevant user's static signal, again result is presented with sound or visible form, for example the user can be directly by light supply apparatus (being green LED 14, yellow light-emitting diode 15, the red light emitting diodes 16 of embodiment) and flexible piezoelectric sound-generating devices (being the loudspeaker 17 of embodiment), learn the electrostatic detection ring of electrostatic testing apparatus and user's connection status in real time, adjust it more according to this.
