Description

Technical Field

[0001] This utility model belongs to the technical field of static electricity removal devices for balances, and particularly relates to a static electricity removal device for balance weighing. Background Technology

[0002] The core purpose of eliminating static electricity during the weighing process of a balance is to ensure the accuracy and stability of the weighing results and avoid systematic errors caused by static electricity. Static eliminators are usually used to eliminate static electricity.

[0003] Currently, static eliminators are placed on the test bench. Before weighing, the experimenters align the sample with the static eliminator to eliminate static electricity. However, the experimenters may make mistakes during the operation, and it is impossible to completely prevent the influence of static electricity on the weighing results. Utility Model Content

[0004] The purpose of this invention is to provide an antistatic device for balance weighing in order to solve the problems mentioned above.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an antistatic device for balance weighing, comprising:

[0006] A cuboid frame with no sharp edges at the front, and multiple casters at the bottom of the cuboid frame;

[0007] A power supply mounting bracket is fixedly connected to the rear end of the cuboid frame;

[0008] Multiple sets of electrostatic induction removal mechanisms are fixedly connected to the edges of the cuboid frame;

[0009] Multiple sets of stop mechanisms are fixedly installed on the edges of the cuboid frame. Each stop mechanism corresponds to and is electrically connected to the electrostatic induction removal mechanism, and the stop mechanism extends into the corresponding opening of the cuboid frame.

[0010] A power module is installed inside the power supply bracket, and the power module supplies power to multiple sets of electrostatic induction removal mechanisms and multiple sets of stop mechanisms.

[0011] As a further description of the above technical solution:

[0012] The electrostatic induction removal mechanism includes a support plate, an electrostatic sensor, and an electrostatic eliminator. The support plate is fixedly connected to the edge of the cuboid frame. The electrostatic sensor and the electrostatic eliminator are both fixedly connected to the support plate. The electrostatic sensor, the electrostatic eliminator, and the power module are all electrically connected to the controller.

[0013] As a further description of the above technical solution:

[0014] The static eliminator is a QP-S35W static eliminator, and the static sensor is a QP-C01 intelligent static sensor.

[0015] As a further description of the above technical solution:

[0016] The stop mechanism includes a servo motor and a stop rod. The servo motor is fixedly connected to the edge of the cuboid frame, and the stop rod is fixedly connected to the output end of the servo motor. The stop rod extends into the corresponding opening, and the servo motor is electrically connected to the controller.

[0017] As a further description of the above technical solution:

[0018] The static eliminator is located between the static inductor and the corresponding opening.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] 1. In this utility model, an opening is provided on the cuboid frame, and the sample must pass through the opening to be sent into the balance. A stop mechanism is set inside the opening, and an electrostatic induction removal mechanism is set on the cuboid frame outside the opening. As the sample is sent to the opening, the electrostatic induction removal mechanism senses and eliminates static electricity. Only when the electrostatic induction removal mechanism can no longer sense the static electricity of the sample will the stop mechanism release the stop on the opening, allowing the uncharged sample to smoothly enter the balance for weighing. This eliminates the possibility of oversight by the experimenter during operation and can absolutely prevent the influence of electrostatics on the weighing results.

[0021] 2. In this utility model, an electrostatic sensor detects the presence of static electricity in the sample to be fed into the opening. The electrostatic sensor sends the detection result to the controller, which controls the switch of the static eliminator. After the static eliminator is turned on, it eliminates static electricity from the sample, thus achieving automatic sensing and elimination of static electricity, which has the effect of saving energy.

[0022] 3. In this utility model, when the electrostatic sensor detects static electricity in the sample, the stop bar extends into the opening, prompting the experimenter to place the sample on the static eliminator to eliminate the static electricity. After the static electricity is eliminated, when the electrostatic sensor no longer detects static electricity in the sample, the controller controls the servo motor to rotate, causing the stop bar to rotate and move away from the opening, allowing the experimenter to smoothly place the sample into the balance for weighing. This eliminates the possibility of oversight by the experimenter during operation and absolutely prevents the influence of electrostatic balance on the weighing results. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-7 This utility model provides a technical solution: an antistatic device for weighing on a balance, comprising:

[0034] A cuboid frame 1, which has no sharp edges at the front end, and a plurality of casters 2 are provided at the bottom of the cuboid frame 1;

[0035] The power supply bracket 3 is fixedly connected to the rear end of the cuboid frame 1;

[0036] Multiple sets of electrostatic induction removal mechanisms 4 are fixedly connected to the edges of the cuboid frame 1;

[0037] Multiple sets of stop mechanisms 5 are fixedly installed on the edges of the cuboid frame 1. The stop mechanisms 5 correspond one-to-one with the electrostatic induction removal mechanism 4 and are electrically connected. The stop mechanisms 5 extend into the corresponding openings 6 of the cuboid frame 1.

[0038] The power module 7 is installed inside the power mounting bracket 3, and the power module 7 supplies power to multiple sets of electrostatic induction removal mechanisms 4 and multiple sets of stop mechanisms 5.

[0039] The electrostatic induction removal mechanism 4 includes a support plate 41, an electrostatic sensor 42, and an electrostatic eliminator 43. The support plate 41 is fixedly connected to the edge of the cuboid frame 1. The electrostatic sensor 42 and the electrostatic eliminator 43 are both fixedly connected to the support plate 41. The electrostatic sensor 42, the electrostatic eliminator 43, and the power module 7 are all electrically connected to the controller 8. The electrostatic sensor 42 senses the presence of static electricity in the sample to be sent into the opening 6. The electrostatic sensor 42 sends the sensing result to the controller 8. The controller 8 controls the switch of the electrostatic eliminator 43. After the electrostatic eliminator 43 is turned on, it eliminates static electricity from the sample, realizing automatic induction and elimination of static electricity, which has the effect of saving energy.

[0040] The static eliminator 43 is a QP-S35W static eliminator, and the static sensor 42 is a QP-C01 intelligent static sensor.

[0041] The stop mechanism 5 includes a servo motor 51 and a stop rod 52. The servo motor 51 is fixedly connected to the edge of the cuboid frame 1, and the stop rod 52 is fixedly connected to the output end of the servo motor 51. The stop rod 52 extends into the corresponding opening 6. The servo motor 51 is electrically connected to the controller 8. When the electrostatic sensor 42 senses that there is static electricity in the sample, the stop rod 52 extends into the opening 6, prompting the experimenter to place the sample on the static elimination rod 43 to eliminate the static electricity. After the static electricity is eliminated, when the electrostatic sensor 42 no longer senses that there is static electricity in the sample, the controller 8 controls the servo motor 51 to rotate, which drives the stop rod 52 to rotate, so that the stop rod 52 leaves the opening 6, allowing the experimenter to smoothly place the sample into the balance for weighing, eliminating the experimenter's oversight during operation, and absolutely preventing the influence of electrostatic balance on the weighing results.

[0042] The static eliminator 43 is located between the static inductor 42 and the corresponding opening 6.

[0043] Working principle: First, the cuboid frame 1 is pushed by the rolling support of the casters 2 to cover the balance, aligning the opening 6 with the balance's loading glass door. When the electrostatic sensor 42 detects no static electricity, the controller 8 controls the servo motor 51 to rotate, causing the stop bar 52 to move away from the opening 6. Second, when the experimenter feeds a sample into the balance, the electrostatic sensor 42 senses whether the sample to be fed into the opening 6 has static electricity. If the sample has static electricity, the electrostatic sensor 42 sends the sensing result to the controller 8, and the controller 8 controls the static elimination rod 43. When the static eliminator 43 is turned on, it eliminates static electricity from the sample. At the same time, the controller 8 controls the servo motor 51 to rotate, and the servo motor 51 drives the stop rod 52 to extend into the opening 6, prompting the experimenter to place the sample at the static eliminator 43 to eliminate static electricity. Finally, after the static electricity is eliminated, when the static sensor 42 can no longer detect static electricity in the sample, the controller 8 controls the servo motor 51 to rotate, driving the stop rod 52 to rotate, so that the stop rod 52 leaves the opening 6, allowing the experimenter to smoothly place the sample into the balance for weighing.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
