[0020] Traditional electrostatic equipment often faces problems when adsorbing powder in a vessel (container), which not only affects the uniform distribution of the powder, but can also cause errors in subsequent experiments. In addition, during the transfer process, the dust on the electrostatic equipment is prone to adsorb some air impurities due to the continuous generation of static electricity, thereby reducing the transfer effect of the powder. More seriously, the electrostatic generators on the market currently generally lack arc protection design. Despite grounding, there is still a risk of fire. When the electrostatic device is placed in a vessel to adsorb powder, the attenuation of the negative static charge in the air will result in the need to increase the static voltage to ensure the adsorption strength. When the discharge grid is close to the vessel, the arc light generated by its strong ionization can easily burn the powder dispersed in the vessel, thereby causing a fire. These problems not only affect the use efficiency of electrostatic equipment, but also bring serious safety hazards. Summary of the invention

[0052] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0053] Embodiment 1:

[0054] See also Figure 1 - Figure 3 A handheld powder electrostatic adsorption transfer device includes: a control component 2, an adsorption component 1 is provided on one side of the control component 2, and the adsorption component 1 can make the powder adsorption more uniform and reduce subsequent experimental errors.

[0055] The adsorption component 1 comprises:

[0056] Adsorption member 11;

[0057] A handle 12 mounted on the bottom of the adsorption member 11;

[0058] A fixing block 14 mounted on the outside of the handle 12;

[0059] A switch 13, which is mounted on one side of the fixing block 14;

[0060] An adjusting member 15 is fixedly mounted on one side of the fixing block 14 and is located below the switch 13;

[0061] A protective tube 16 mounted on the bottom of the handle 12;

[0062] The material removal assembly 17 is installed inside the adsorption member 11 .

[0063] The specific implementation method is that a number of anti-slip parts are installed on the outside of the handle 12 to prevent the subsequent work from being affected by hand slipping during the work process. The user can manually or automatically adjust the size of the electrostatic force through the adjustment part 15 according to the quality of the powder and the adsorption requirements. The electrostatic force adjustment system has a built-in high-precision power module to ensure the stable output of the electrostatic force. Through the adjustment part 15, combined with the high-precision power module, the electrostatic force can be accurately controlled to meet the adsorption requirements of different powders. The adsorption part 11 uses high-voltage insulating materials: used to make insulating parts of high-voltage generators, such as epoxy resin, ceramic or glass fiber. These materials have good insulation properties and high temperature resistance, which can ensure the safe operation of high-voltage circuits.

[0064] The blanking assembly 17 comprises:

[0065] The rotating power member 171 is fixedly installed inside the adsorption member 11;

[0066] Two symmetrically arranged rotating shafts 172 are fixedly mounted on the output end of the rotating power member 171:

[0067] Two sets of eccentric wheels 173 are sleeved on the outer side of the rotating shaft 172 .

[0068] The specific implementation method is that the rotating power part 171 includes but is not limited to a DC motor, which is electrically connected to an external power supply and controlled by a PLC programming program inside the control component 2. The output end of the rotating power part 171 has a coupling, which is fixedly connected to the rotating shaft 172 through the output end, and is used to drive the rotating shaft 172 to rotate, further drive the eccentric wheel 173 to rotate, drive the adsorption part 11 to vibrate, and shake the powder off.

[0069] The control component 2 includes:

[0070] A control line 22, one end of which is fixedly mounted to the bottom of the protection tube 16;

[0071] A control box 21, which is fixedly connected to the other end of the control line 22;

[0072] The display screen 23 is fixedly mounted on one side of the control box 21 .

[0073] The specific implementation method is that the control box 21 is equipped with an intelligent control system: an algorithm model is used to automatically calculate and adjust the electrostatic force according to the gravity changes of the adsorbed powder monitored in real time by a balance or gravity sensor. When the adsorption gravity reaches the threshold preset by the user, the intelligent control system automatically cuts off the power and stops adsorption to avoid powder layer accumulation and uneven thickness. An algorithm model is used in conjunction with a balance or gravity sensor to monitor the gravity changes of the adsorbed powder in real time, and automatically adjust the electrostatic force to avoid powder bed accumulation and uneven thickness.

[0074] Embodiment 2:

[0075] See also Figure 1 , Figure 2 and 4 This embodiment provides a technical solution based on the first embodiment: it includes: a control component 2, an adsorption component 1 is provided on one side of the control component 2, and the adsorption component 1 can make the powder be adsorbed more evenly and reduce subsequent experimental errors.

[0076] The adsorption component 1 comprises:

[0077] Adsorption member 11;

[0078] A handle 12 mounted on the bottom of the adsorption member 11;

[0079] A fixing block 14 mounted on the outside of the handle 12;

[0080] A switch 13, which is mounted on one side of the fixing block 14;

[0081] An adjusting member 15 is fixedly mounted on one side of the fixing block 14 and is located below the switch 13;

[0082] A protective tube 16 mounted on the bottom of the handle 12;

[0083] The material removal assembly 17 is installed inside the adsorption member 11 .

[0084] The negative voltage component 18 includes:

[0085] A plurality of negative voltage generators 181 are fixedly installed in a linear array inside the adsorption member 11;

[0086] A plurality of connection lines 182 are fixedly installed in a linear array between two adjacent negative voltage generators 181 .

[0087] The specific implementation is that the negative voltage component 18 transfers the powder adsorbed on the instrument to other containers smoothly by applying negative voltage. During the transfer process, the negative charge transfer mechanism avoids the adsorption of air impurities and improves the purity of the powder by accurately controlling the release of electrostatic force.

[0088] Embodiment three:

[0089] In the first embodiment, when the electrostatic adsorption force needs to be automatically adjusted, it can be achieved through the following algorithm:

[0090]

[0091] Among them, F ad The amount of electrostatic adsorption force required to adsorb the powder;

[0092] N is the number of turns of the electromagnet coil;

[0093] k is the proportionality constant measured experimentally;

[0094] μ is the magnetic permeability of the iron core in the electromagnet, and l is the effective length of the iron core in the electromagnet.

[0095] The specific implementation is that a weight sensor is provided on the inner side of the adsorption member 11, which can convert the weight of the adsorbed powder on the outer side of the adsorption member 11 into electric current and transmit it to the control box 21. The PLC programming program in the control box 21 monitors the transmitted current in real time and uses the above formula to control the electrostatic adsorption force of the device, and displays the converted data on the display screen 23, so that the user can adjust the adsorption force more intuitively.

[0096] Working principle: When in use, turn on the power through the switch 13 on the handle 12 to fill the high-voltage electrostatic field and adsorb the powder. The size of the electrostatic force can be adjusted manually or automatically through the adjustment part 15 according to the quality of the powder and the adsorption requirements. When the powder needs to be scattered, two different methods can be selected after turning off the power;

[0097] 1. Start the rotating power member 171, which drives the rotating shaft 172 to rotate through the output end, and further drives the eccentric wheel 173 to rotate, vibrating the adsorption member 11, and shaking the powder off the surface of the adsorption member 11, thereby completing the transfer work;

[0098] Second: Start the negative voltage generator 181 and transfer the powder adsorbed on the device to other containers smoothly by applying negative voltage. During the transfer process, the negative charge transfer mechanism avoids the adsorption of air impurities and improves the purity of the powder by precisely controlling the release of electrostatic force.

[0099] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
