Abstract
Description
Technical Field
[0001] This utility model relates to the field of laboratory auxiliary equipment technology, and in particular to a staining auxiliary device for laboratory use. Background Technology
[0002] In existing technologies, laboratory manual staining experiments often require the sequential use of multiple dye solutions, with strict requirements on the contact time of each solution at different steps. Most existing solutions rely on a single timer, necessitating manual setting of the timer for each stage and resetting it between steps. Furthermore, the timer is often separate from the dye solution holder, requiring the operator to pick it up or repeatedly check the timing screen, resulting in a cumbersome process, prone to errors, and inconsistent staining results. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide a staining auxiliary device for the laboratory, which enables individual timing and display of experimental time for each stain bottle, thereby simplifying the experimental process.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a staining auxiliary device for a laboratory, comprising a main control module, a bracket body, multiple sensing modules, multiple timing modules, multiple display modules, and multiple alarm modules; the bracket body is provided with multiple receiving slots; the number of the receiving slots, sensing modules, timing modules, display modules, and alarm modules corresponds one-to-one; the sensing modules, timing modules, display modules, and alarm modules are all connected to the main control module;
[0005] The sensing module is located at the bottom of the receiving tank, which is used to hold the dye bottle. The sensing module senses whether the dye bottle is placed in the current receiving tank and sends the position signal of the dye bottle to the main control module. The main control module receives the position signal and sends a control signal to the timing module and the display module. The display module displays the current experimental time, and the timing module records the experimental time. After the experimental time reaches the time threshold, the timing module sends a time signal to the control module, and the control module sends an alarm signal to the alarm module.
[0006] In a preferred embodiment, the system further includes a button module for setting the time threshold; the number of button modules corresponds one-to-one with the number of receiving slots.
[0007] In a preferred embodiment, the sensing module is specifically a pressure sensor, which senses pressure information after the dye bottle is placed in the receiving tank.
[0008] In a preferred embodiment, the display module is specifically an OLED display screen used to display the current experiment time.
[0009] In a preferred embodiment, the timing module uses a PCF8563 chip.
[0010] In a preferred embodiment, the main control module uses an ESP32-WROOM-32 chip.
[0011] In a preferred embodiment, a power module is also included.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1) Solved the problem that a single timer is only applicable to a single dye solution;
[0014] 2) Different timing durations can be set for different dye bottles, which is convenient and quick. Attached Figure Description

[0020] A staining aid for laboratory use, reference Figure 1-2The system includes a main control module, a bracket body 1, multiple sensing modules 3, multiple timing modules, multiple display modules 5, and multiple alarm modules. The bracket body is provided with multiple receiving slots 4 for accommodating the dye bottles 2. The number of each of the receiving slots 4, dye bottles 2, sensing modules 3, timing modules, display modules 5, and alarm modules corresponds one-to-one. Each of the sensing modules 5, timing modules, display modules 5, and alarm modules is connected to the main control module.
[0021] The sensing module 3 is located at the bottom of the receiving tank 4; the sensing module 3 senses whether the dye bottle 2 is placed in the current receiving tank 4, and sends the position signal of the dye bottle 2 to the main control module. The main control module receives the position signal and sends a control signal to the timing module and the display module 5. The display module 5 displays the current experimental time, the timing module records the experimental time, and after the experimental time reaches the time threshold, the timing module sends a time signal to the control module, and the control module sends an alarm signal to the alarm module.
[0022] Specifically, it also includes a button module 6, which is used to set the time threshold; the number of button modules 6 corresponds one-to-one with the dye bottles 2. In this embodiment, the button module 6 can be a matrix button, such as a 4×5 keyboard, paired with a 74HC995 row and column driver. The dyeing time for each application is preset via the button module 6.
[0023] Specifically, the sensing module is a pressure sensor. After the dye bottle is placed in the receiving tank, the pressure sensor senses the pressure information. The pressure sensor can be a chip SCT015G. When the dye bottle 2 is placed in the receiving tank 4, the pressure sensor senses the pressure information and sends a signal to the main control module to inform the main control module that the timing can start. The main control module then sends a timing signal to the timing module.
[0024] Specifically, the display module is an OLED display screen used to display the current experiment time.
[0025] Specifically, the timing module uses the PCF8563 chip.
[0026] Specifically, the main control module uses the ESP32-WROOM-32 chip.
[0027] Specifically, the alarm module is a buzzer.
[0028] Specifically, it also includes a power module. The power module comprises a battery and a charging circuit, the latter converting externally input power to meet battery charging requirements. The use of either an external power source or an internal battery ensures the reliable operation of the laboratory staining timer.
[0029] Working process: The dye bottle 2 is placed in the receiving tank 4. The pressure sensor detects the pressure information and sends a signal to the main control module, informing the main control module that timing can begin. After receiving the signal from the pressure sensor, the main control module sends a timing signal to the timing module, which then starts timing. The dye reaction time is preset via the button module 6. The remaining experimental time is displayed on the display module 5 using the timing function of the timing module. When the time reaches the threshold, the control module sends an alarm signal to the buzzer, which sounds to remind the experimenter to proceed to the next experimental step. This avoids the cumbersome experimental steps of requiring separate timing each time in existing technologies, simplifying the experimental process.
