Description

Technical Field

[0001] The invention relates to the field of electrophoresis apparatus, in particular to an electrophoresis apparatus monitoring device. Background Art

[0002] During the electrophoresis process, in order to facilitate the observation of the progress of electrophoresis, a marker color is added to the test sample. The marker color will move synchronously with the test sample to the bottom of the gel during the electrophoresis process, and the electrophoresis should end when the gel moves to the bottom of the gel (in the electrode core). However, in reality, the time of the electrophoresis test varies depending on parameters, samples and other conditions, and the general duration of electrophoresis is also relatively long. Therefore, one can only manually observe and wait for the color ribbon to reach the bottom of the gel and manually shut down the electrophoresis instrument, which consumes a lot of time and energy of the experimenter.

[0033] like Figure 2 and Figure 3 As shown, the inner walls of black box one 101 and black box two 102 are coated with a black coating that absorbs light, black box one 101 and black box two 102 are both arranged horizontally, and the size of black box two 102 is smaller than that of black box one 101, the opening of black box two 102 is opposite to the opening of black box one 101, and guide pillars 100a are vertically arranged at the four corners of the electrophoresis tank 100, and the guide pillars 100a are made of ceramic material, the top of the guide pillars 100a is fixedly connected to the inner wall of the electrophoresis tank 100, and the bottom of the guide pillars 100a is fixedly plugged into the bottom of the electrophoresis tank 100, and the outer walls on both sides of the black box one 101 and black box two 102 are slidably connected to the guide pillars 100a.

[0034] It should be noted that the marking color of the color band used in the electrophoresis of the electrode core 300 is blue.

[0035] The present invention proposes an electrophoresis apparatus monitoring device, which is designed based on the electrophoresis tank 100 of the existing electrophoresis apparatus and mainly includes two parts, namely, a signal generating part for identifying color and a switch control part for identifying the positive connection between the electrophoresis apparatus and the electrode core 300. Figure 3 As shown, the signal generating part includes a photovoltaic cell 103 connected in series, a light strip 104 of an LED light source, and a black box 101 and a black box 2 102 for eliminating light interference, as shown in FIG. Figure 5 As shown, the switch control part is mainly composed of a relay 201, an electromagnetic push rod 202 and a resistor assembly 204. The basic principle is very simple. The light strip 104 emits white light that passes through the glass plate of the transparent electrode core 300 and the gel therein to reach the photovoltaic cell 103. The photovoltaic cell 103 generates electricity to generate an electrical signal. The electrical signal controls the switch of the positive circuit between the electrophoresis instrument and the electrode core 300 through the relay 201.

[0036] It should be noted that the surface of the photovoltaic panel has a blue luster because there is a layer of blue coating. The green light has the highest photovoltaic power generation efficiency. The photoelectric conversion efficiency of blue light is very low. Therefore, the blue light irradiated on the photovoltaic panel not only has a very low benefit, but also causes heat. Therefore, it is a preferred choice to reflect the inefficient blue light waves through the blue coating.

[0037] Back to the present invention, when the color band formed by the blue marker and the test sample does not reach the bottom of the gel in the electrode core 300, the white light of the light strip 104 enables the photovoltaic cell 103 to generate sufficient power, forming a higher output current and voltage, that is, a high potential signal, refer to Figure 2 When the color ribbon drops to the bottom of the gel in the electrode core 300, it will reach between the photovoltaic cell 103 and the light strip 104. After the white light passes through the blue color ribbon, most of the other colors of light are absorbed by the color ribbon. Only the blue light that is not absorbed by the blue color ribbon can pass relatively smoothly. When most of the light irradiating the photovoltaic cell 103 is blue light, the power generation of the photovoltaic cell 103 will plummet, thereby outputting very low current and voltage, that is, a low potential signal.

[0038] Therefore, it can be seen that when the potential signal is high, the control end of the relay 201 can obtain sufficient voltage and current to open its load end, that is, the positive circuit between the electrophoresis instrument and the electrode core 300 is connected, and the electrophoresis instrument works normally. When the potential signal is low, the relay 201 will disconnect the positive circuit between the electrophoresis instrument and the electrode core 300, and the electrophoresis is stopped.

[0039] To achieve the above-mentioned objective functions, the present invention also involves the following technical details:

[0040] First, the black box 101 and the black box 2 102 process light. Since the preparation process of the electrophoresis test needs to be operated while observing, the accessories such as the electrophoresis tank 100 of the electrophoresis are transparent and are not easy to be designed to be black or a color with low light transmittance. Therefore, when the photovoltaic cell of the present invention is working, it will be subject to a large amount of interference light refracted and reflected from inside and outside the electrophoresis tank 100, making it difficult for the photovoltaic panel to accurately generate electrical signals;

[0041] Therefore, in the device, under ideal conditions, the external light cannot illuminate the photovoltaic cell 103, and the light of the light strip 104 is preferably irradiated on the photovoltaic cell 103 in a straight line. Therefore, flat and narrow black box 101 and black box 2 102 are designed. The absorption effect of their coating makes the stray light scattered by the light strip 104 absorbed by the black box, and at the same time plays a shielding role, so that the external stray light cannot illuminate deep into the black box. Therefore, the oblique light irradiated by the non-parallel black box 101 and black box 2 102 can be effectively filtered. The device also uses a strip lens to make the light of the light strip 104 as concentrated as possible to irradiate the photovoltaic cell 103, further improving the intensity of the effective light and ensuring that the photovoltaic cell 103 is within the designed working power range.

[0042] Second, the resistance component 204 with a variable resistance value, refer to Figure 6 and Fig. 9 The resistor 207 of the resistor assembly 204 is connected in series circuit in the following manner: Fig. 9 Take a as the starting point, and then go through a resistor 207 to get to b, b and c belong to the same copper sheet 208, and then go through a resistor 207 from c to get to d, d and e also belong to the same copper sheet 208, and so on until six resistors 207 are connected in series and finally get to g;

[0043] Referring to 5, when the load end of the relay 201 is disconnected, the main circuit between the electrophoresis apparatus and the electrode core 300 is disconnected. At this time, the resistor component 204 is connected between the electrophoresis apparatus and the electrode core 300, and the circuit is not completely disconnected. At this time, after the electromagnetic push rod 202 loses power, the spring 210 pushes the copper rod 203 downward. During the process:

[0044] First, the top of the copper rod 203 contacts the contact 208a on the copper sheet 208 marked with b and c. At this time, the only resistor 207 connected in series in the circuit is the resistor 207 between the copper sheet 208 marked with a and the copper sheet 208 marked with bc. The resistance value of the circuit is low.

[0045] When the copper rod 203 moves downward to the point where its top contacts both the contact 208a of the bc copper sheet 208 and the contact 208a of the de copper sheet 208 which is relatively lower, the resistor 207 between the mark d and the mark c is in a short-circuited state, so there is still only one resistor 207 working.

[0046] When the copper rod 203 continues to descend and separates from the contact 208a on the bc copper sheet 208 and only contacts the contact 208a on the de copper sheet 208, two resistors 207 are connected in series in the circuit, and the resistance in the circuit increases;

[0047] Similarly, when the copper rod 203 only contacts the contact 208a on the copper sheet 208, all six resistors 207 are connected in series in the circuit. At this time, the resistance value of the resistance component 204 in the circuit transitions to the maximum, and finally the copper rod 203 is separated from the resistance component 204, and the circuit is completely disconnected;

[0048] The buffer mechanism 200 slides in the resistor assembly 204 through the copper rod 203, so that the resistance in the circuit gradually increases and the current in the circuit gradually decreases. Firstly, it avoids the impact damage to the electrophoresis instrument circuit caused by sudden circuit disconnection. Secondly, it provides the electrophoresis instrument with sufficient self-test reaction time to protect the electrophoresis instrument equipment when automatically identifying the end of the electrophoresis test and disconnecting the circuit.

[0049] Thirdly, when the load end of the relay 201 is closed, the load resistor 211 can prevent the wire from directly short-circuiting the electromagnetic push rod 202, thereby ensuring the normal operation of the electromagnetic push rod 202. When the load end of the relay 201 is disconnected, an independent loop is formed between the coil of the electromagnetic push rod 202 and the load resistor 211. Therefore, when the shaft of the electromagnetic push rod 202 is reset under the push of the spring 210, an induced current and a corresponding electromagnetic field will be generated due to the closed loop, which will hinder the reset of the shaft of the electromagnetic push rod 202, which is manifested as a slower reset speed of the shaft of the electromagnetic push rod 202, thereby slowing down the time for the resistor component 204 to disconnect the series circuit, so that during the line disconnection process, the resistance value of the resistor component 204 increases more slowly, thereby giving the electrophoresis instrument a longer response time, further protecting the circuit safety of the electrophoresis instrument.

[0050] In summary, the device uses components such as photovoltaic cells 103 and light strips 104, supplemented by a specifically designed black box structure, to achieve the color recognition function that can only be achieved by expensive color sensors without affecting the conventional electrophoresis visual operation, with very cheap electronic components and a simple structural layout design. In addition, through the resistor component 204 with a variable resistance design, in conjunction with the electromagnetic push rod 202 and the relay 201, circuit protection for the electrophoresis instrument is also achieved when the circuit is disconnected.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
