[0002] At present, due to the existence of a large number of positive and negative ions in nature, a certain electrostatic force will be generated. Electrostatic force refers to the interaction force between stationary charged bodies. Charged bodies can be regarded as composed of many point charges. The interaction force between each pair of stationary point charges follows Coulomb's law, also known as Coulomb force.

[0003] In order to understand the adsorption force of electrostatic force, it is often necessary to test the adsorption force of electrostatic force. The existing method can only rely on placing the hand under the high-voltage generator rod and judging the performance of the generator rod by the degree of erection of sweat hair, or directly judging whether the generator rod can meet the performance requirements by the yield of the production product. These two methods have the following disadvantages: 1. The specific electrostatic adsorption force cannot be quantified, resulting in no data for reference, and misjudgment often occurs; 2. Danger, when the discharge amount is large, it will discharge to the human hand, causing numbness in the user's hand, which is easy to cause discomfort to the user; 3. Hysteresis, for this reason, we propose an electrostatic adsorption force test device and its use method. Summary of the invention

[0004] The purpose of the present invention is to provide an electrostatic force adsorption force testing device and a method for using the same. A certain voltage is applied to a generating rod to be tested so that it emits positive and negative ions toward a membrane to be tested. The membrane to be tested will then generate a certain adsorption force with an adsorption plate. When the adsorption is completed, the adsorption plate is pushed and pulled, thereby driving the movement of the membrane to be tested and then driving the rod of a push-pull force gauge to move, thereby generating a certain push-pull force. According to the readings displayed by the push-pull force gauge, it is determined whether the number of positive and negative ions emitted by the generating rod meets the requirements for on-site use.

[0014] In a second aspect, the present invention provides a method for using the electrostatic force adsorption force testing device as described above, and the specific steps of the method are as follows: S1. By pressing the rotating round block inward, the rotating round block drives the push rod and its pushing ball to move, so that the pushing ball squeezes the forward pushing groove, and at the same time pushes the two pushing blocks to move, and the pushing blocks drive the movable rectangular rod to move, so that the connecting rod and its clamping block move, until the pushing ball is located inside the reverse pushing groove. At this time, the reset spring drives the pushing block to return to its original position, so that the clamping block is clamped with the clamping groove, and then the slider moves along the column to adjust the height of the generating rod, and then the extrusion assembly is driven to move by the turning handle assembly, so that the locking assembly squeezes the inner wall surface of the column, so as to lock the height of the slider; S2, by adjusting the high voltage generator and the medium and low voltage generator, the power supplies of the high voltage generator and the medium and low voltage generator apply a certain voltage to the generating rod, the film to be tested is mounted on the clamping assembly and fixed, and the film to be tested is laid flat on the adsorption plate; S3, adjust the reset timer, test timer and power-on timer to power on, after the hold and release time are completed, start the power switch button, at this time the generating rod will generate a certain amount of positive and negative ions to be emitted to the membrane to be tested, and a certain adsorption force will be generated between the membrane to be tested and the adsorption plate; S4. By pressing the test button, the electric push-pull assembly drives the adsorption plate to move forward and backward. Due to the existence of friction, the adsorption plate drives the film to be tested to move forward and backward, and at the same time drives the tension end of the push-pull force gauge to move forward and backward, thereby generating a push-pull force reading.

[0015] Technical effects and advantages of the present invention: The film to be tested is fixed by a clamping assembly, and then the film to be tested is laid flat on the top of the adsorption plate, and then the height of the generating rod is adjusted by the lifting platform, and then the electrostatic adsorption force test platform provides voltage to the generating rod, so that the film to be tested is adsorbed on the adsorption plate, and then the adsorption plate is driven to move by the electric push-pull assembly. Due to the adsorption force between the adsorption plate and the film to be tested, the moving adsorption plate will drive the film to be tested to move, thereby driving the rod of the push-pull force meter to extend, thereby generating a push-pull force reading. This design quantifies the electrostatic adsorption force through the push-pull force indication, which is convenient for fully understanding the size of the electrostatic adsorption force, while reducing the situation of misjudgment, and also avoids testing through human senses, reducing the danger, and the overall test results can also reflect the situation of the electrostatic adsorption force in a timely manner; The double-headed threaded rod is driven to rotate by the turning handle assembly, and the threads of the double-headed threaded rod and the extrusion block are used to drive the two extrusion blocks to approach each other, so that the pressure block moves, and then the movable block is driven to move, and then the extrusion plate and its anti-skid pad are driven to move, so that the anti-skid pad contacts and squeezes the inner wall surface of the sliding cavity inside the column, so as to achieve the position of the slider locked by the locking assembly, thereby locking the height of the slider and its generating rod. When the slider needs to be moved later, the turning handle assembly is used to drive the double-headed threaded rod to reverse, so that the extrusion block no longer squeezes the pressure groove, and the slider can be moved; By moving the rotating round block outward, the pushing ball squeezes the reverse push groove, causing the pushing block to move, thereby causing the connecting rod to move, causing the clamping block to disengage from the clamping groove. As the rotating round block is further moved outward, the connecting rod gradually separates from the slot. When the pushing ball is located in the forward push groove, the reset spring resets, driving the connecting rod to reset. Subsequently, the rotating round block is rotated in time without causing the rotating block to rotate. Then, even if the rotating round block is pressed inward, since the connecting rod will not be inserted into the slot, even if the rotating round block is accidentally touched at this time, the turning handle assembly will not drive the double-headed threaded rod to rotate, thereby having a good anti-accidental touch function.

At this time, the pushing ball 2805 pushes the positive pushing slot 2802, so that the two pushing blocks 2801 move away from each other, so that the movable rectangular rod 2501 moves, thereby driving the connecting rod 2502 and its block 2504 to move, thereby pressing The return spring 2503 is compressed, and as the rotating ball 2403 gradually moves inward, the connecting rod 2502 is inserted into the slot 2505.

When the film to be tested 4 needs to be removed, the rotating block 503 is rotated to make the horizontal block 505 rotate along the rotating body 504 until the rubber protrusion 506 is aligned with the through groove 509, and then the rotating block 503 is moved upward to make the rubber protrusion 506 enter the through groove 509. At this time, the clamping rubber pad 508 no longer squeezes and fixes the film to be tested 4, and the film to be tested 4 can be removed.
