Description

Technical Field

[0001] The invention relates to a monomer component debugging and positioning method, in particular to a monomer component debugging and positioning method based on a photoelectric sensor. Background Art

[0002] During the production process of medical devices (equipment, devices, and instruments), it's often necessary to align and debug the relative positions of two or more individual components, vertically, horizontally, and front to back. For example, in medical testing, the transmittance of a test kit must be tested, and this must be done under sealed, opaque conditions. This requires aligning two or more individual components. Failure to ensure component alignment can result in unnecessary light entering the test kit, affecting the transmittance test and ultimately impacting product quality. Currently, during component alignment, one component's position is often used as a reference. A host computer controls the stepper motor driver pulse parameters to adjust the position of another component, achieving alignment between the two components.

[0003] The shortcomings of the above-mentioned single component debugging method are:

[0004] 1. When the upper computer controls the pulse parameters of the stepper motor driver to debug the position of the single component, the number of stepper motor pulse parameters, as well as the direction and position of the single component movement need to be judged by manual visual inspection. Manual visual inspection of the direction and distance of movement of the single component results in inaccurate movement of the single component, many movements, and long debugging time, which ultimately leads to low accuracy in debugging the position of the single component.

[0005] 2. Manual visual inspection has low debugging efficiency and high labor costs, and the risk of unqualified equipment performance indicators after debugging increases.

[0006] 3. Manual visual inspection and debugging lack a position reference, and the consistency of position debugging of the same type of single components cannot be guaranteed. Summary of the Invention

[0007] The present invention aims to provide a method for debugging and positioning a single component based on a photoelectric sensor, so as to ensure the accuracy and consistency of the position debugging of the single component.

[0008] To achieve the above object, the present invention adopts the following technical solutions:

[0009] The method for debugging and positioning a single component based on a photoelectric sensor of the present invention adopts the following special debugging and positioning device;

[0010] The dedicated debugging and positioning device includes a substrate and a power supply unit arranged on the substrate; a horizontal debugging and positioning unit and a vertical debugging and positioning unit are arranged on the front surface of the substrate, and a connection positioning unit is arranged on the back surface of the substrate;

[0011] The lateral debugging and positioning unit is used to perform lateral displacement positioning on the debugged single component;

[0012] The longitudinal debugging and positioning unit is used to perform longitudinal displacement positioning on the debugged single component;

[0013] The connection and positioning unit is used to connect a reference monomer component, wherein the reference monomer component refers to a monomer component designated as a reference among two or more monomer components to be debugged on the medical device;

[0014] The power supply unit is used to supply power to the horizontal debugging and positioning unit and the vertical debugging and positioning unit;

[0015] The debugging and positioning method comprises the following steps:

[0016] Step 1: First, according to the positioning size requirements of the reference monomer component to be debugged on the medical device, adjust the connection positioning unit on the back plate surface of the base plate to a position matching the positioning size and then lock it;

[0017] Step 2: Fix the reference monomer assembly to the connection and positioning unit through the connecting piece;

[0018] Step 3: According to the positioning size requirements of the single component to be debugged on the medical device, the horizontal debugging positioning unit and the vertical debugging positioning unit on the front surface of the base plate are adjusted to positions matching the positioning size and then locked;

[0019] Step 4: The host computer drives the debugged monomer component to move laterally toward the lateral debugging positioning unit by controlling the pulse parameters of the stepper motor driver. When the debugged monomer component moves to the preset position of the lateral debugging positioning unit, it stops. The lateral debugging of the debugged monomer component is completed, and the host computer saves the pulse parameters.

[0020] Step 5: The host computer drives the debugged monomer component to move longitudinally toward the longitudinal debugging positioning unit by controlling the pulse parameters of the stepper motor driver. When the debugged monomer component moves to the preset position of the longitudinal debugging positioning unit, it stops. The longitudinal debugging of the debugged monomer component is completed, and the host computer saves the pulse parameters.

[0021] Optionally, the horizontal debugging and positioning unit and the vertical debugging and positioning unit have the same structure, including:

[0022] a first guide rail, a first slider with a locking mechanism provided on the first guide rail, a carrying plate fixed to the first slider, a position detection mechanism and a stopper mechanism provided on the carrying plate, the position detection mechanism being configured to detect movement of the stopper mechanism, and sending a position detection signal to a host computer when the stopper mechanism moves to a detection position of the position detection mechanism;

[0023] The connection and positioning unit includes a first transverse guide rail and a second transverse guide rail arranged on two opposite edges of the back plate surface of the substrate, and a first transverse slider and a second transverse slider respectively arranged on the first and second transverse guide rails. The first and second transverse sliders are respectively fixedly connected to the two ends of the longitudinal guide rail, and a longitudinal slider is provided on the longitudinal guide rail, and the connecting member for fixing the reference monomer assembly is provided on the longitudinal slider.

[0024] Furthermore, the position detection mechanism includes: an adjustment seat and a photoelectric sensor arranged on the adjustment seat; the block mechanism includes: a linear slide rail, a slider arranged on the linear slide rail, a baffle plate fixed on the slider, a spring seat provided on one side of the baffle plate, and a protrusion provided on the other side of the baffle plate; a pressure spring is provided on the spring seat, and the pressure spring is used for returning the baffle plate; of course, the photoelectric sensor can also be replaced by a micro switch, a Hall sensor or other position sensor.

[0025] Furthermore, the connecting piece for fixing the reference monomer assembly is a pin screwed on the longitudinal slider.

[0026] Optionally, the power supply unit includes a power supply box, and the power supply box is fixed to the front surface of the base plate by snap fastening.

[0027] By providing a horizontal debugging positioning unit, a vertical debugging positioning unit, and a connection positioning unit, the present invention can accommodate the positioning requirements of individual components in different scenarios, providing high flexibility and practicality. Position sensors are used to determine the position of the individual components being debugged, replacing manual visual verification. Clear standards eliminate the need for repeated manual debugging and confirmation, significantly improving accuracy and work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The position detection mechanism is used to detect the movement of the block mechanism, that is, when the sensing end 17 of the shielding plate 13 moves between the light emitter and the receiver of the photoelectric sensor 9, the photoelectric sensor 9 sends a position signal to the host computer.

[0044] Beneficially or exemplarily, as Figure 5 As shown, the connection and positioning unit includes a first transverse guide rail 18 and a second transverse guide rail 19 arranged on two opposite edges of the back panel of the substrate 1, and a first and a second transverse slider 20, 21 respectively arranged on the first and second transverse guide rails 18, 19.

[0045] The debugging and positioning method of the present invention comprises the following steps:

[0046] Step 1: First, according to the positioning size requirements of the reference monomer component to be debugged on the medical device, adjust the connection positioning unit on the back surface of the base plate 1 to a position that matches the positioning size; that is:

[0047] Adjust the positions of the first and second transverse sliders 20, 21 and the longitudinal sliders 23, 24 to match the positioning dimensions of the reference monomer assembly, and then lock them in place using the positioning pins on the first and second transverse sliders 20, 21 and the longitudinal sliders 23, 24;

The electrical sensor 9 sends a positioning signal to the host computer. The longitudinal debugging of the debugged monomer component is completed. The host computer saves the pulse parameters to ensure the consistency of the position debugging of the next monomer component of the same type.
