Detailed Description

In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In one embodiment of the present application, as shown in fig. 1, the integrated test system of the stapler may include:

a cutting assembly testing device 2 for testing the closing force and clamping force of the cutting assembly of the stapler;

the motor testing device 3 is used for testing the working state of a driving motor of the anastomat under a preset load force;

an electrical component testing device 4 for testing the electrical signals of the circuit board and the battery of the stapler;

the main control machine 1 is respectively connected with the cutting component testing device 2, the motor testing device 3 and the electric component testing device 4;

the main control machine 1 is used for determining whether the anastomat is qualified according to the test results of the cutting assembly testing device 2, the motor testing device 3 and the electrical assembly testing device 4.

At present, when the anastomat is tested, workers mainly operate the anastomat manually, and the performance and the quality of the anastomat are judged by observing the suturing speed, the suturing force, the cutting gap speed of a blade, the suturing effect and the like when the anastomat is used for suturing a wound of a virtual tissue. However, this test method can only roughly judge the suture performance of the stapler. Once the performance and quality of the stapler is found to not meet the usage requirements, it is difficult to determine the root cause of the problem intuitively and accurately from the suture test results alone. This suture test result also makes it difficult to provide reliable data basis for subsequent stapler improvements.

Therefore, in the application, based on the structure of the anastomat, a plurality of key components at least comprising a cutting assembly, a driving electrode, a circuit board, a battery and the like of the anastomat are divided, a corresponding testing device is set for each key component, the clamping force and the closing force which influence the suturing effect are tested through the cutting assembly testing device 2, a motor used for driving the cutting assembly to complete suturing is tested through the motor testing device 3, electric signals output by the circuit board and the battery are tested through the electric assembly testing device 4 so as to judge whether the circuit board and the battery can normally work or not, the detailed and comprehensive testing of each component of the anastomat is realized, the root cause that the performance and the quality of the anastomat do not reach the standard is favorably found, and the problem that the wound of a patient is adversely affected due to the quality problem of the anastomat is avoided on the basis of determining that the performance of each key component is good, is beneficial to the smooth use of the anastomat in the wound suturing process.

It should be noted that, because the main control computer needs to be in communication connection with the plurality of test devices, when actually performing a test, a communication protocol between the main control computer and each test device may adopt a master-slave communication connection, that is, a worker initiatively initiates an instruction through the main control computer to start a test of each test device, and the main control computer initiatively acquires test data of each test device, thereby avoiding a problem that a plurality of test devices send information to the main control computer at the same time, which results in data transmission conflict.

Each test device in the integrated test system of the stapler will be described below in a specific embodiment.

As shown in fig. 2, the cutting assembly testing apparatus 2 may include:

the tissue simulator comprises a tissue simulator 2-1, a clamping force testing component 2-2 and a supporting component 2-3;

wherein, a film pressure sensor is arranged in the tissue simulator 2-2 and is used for being clamped and bitten by a jaw of the cutting assembly 0-1, and the closing force of the jaw is tested by the film pressure sensor;

the clamping force testing assembly 2-2 comprises a clamping force sensor and a first motor; one end of the clamping force sensor is connected with one end of the tissue simulator 2-1 which is not clamped by the jaw, and the other end of the clamping force sensor is connected with the first motor; the first motor is used for pulling the tissue simulant to a position far away from the jaw, and the clamping force sensor is used for obtaining the clamping force of the jaw by detecting the tension force applied to the tissue simulant;

the support assembly 2-3 is adapted to support the mounting bar of the cutting assembly to maintain the axis of the mounting bar and the tension applied by the first motor to the tissue simulant at the same level.

As shown in fig. 3, the tissue simulator 2-1 is used for simulating human or animal body tissue, particularly EVA material simulators can be adopted, the tissue simulator 2-1 can adopt a rectangular plate-shaped structure, and the length and the width of the rectangular plate-shaped structure are slightly larger than those of the jaws 0-11, so that the jaws 0-11 can be ensured to be capable of fully biting the tissue simulator 2-1; the thickness of the tissue mimic 2-1 may be set between one-half to two-thirds of the height of the staple. The nail height refers to the height of a nail used by the stapler in suturing a wound.

In the cutting assembly testing device 2, a supporting assembly 2-3 for supporting a cutting assembly 0-1 to be tested and a clamping force testing assembly 2-2 are arranged on a base 2-7. Tissue mimic 2-1 is placed within jaws 0-11 of cutting assembly 0-1. When the test is carried out, only the jaws 0-11 need to be closed, the jaws 0-11 can clamp and bite the tissue simulator 2-1, the film pressure sensor is arranged in the tissue simulator 2-1, the clamping and biting closing force of the jaws 0-11 on the tissue simulator 2-1 can be measured through the film pressure sensor, and then whether the closing force of the jaws 0-11 when the jaws 0-11 are closed reaches the standard or not is determined.

Further, the clamping force testing assembly 2-2 includes a first drive motor 0-2-21 that pulls the tissue simulant 2-1 outwardly toward the jaws 0-11. At the same time, the clamping force sensor 2-22 between the tissue simulant 2-1 and the first driving motor 0-2-21 can measure the pulling force applied by the first driving motor 0-2-21 to the tissue simulant 2-1, and based on the principle of acting force and reacting force, the pulling force is also the clamping force of the cutting assembly 0-1 to clamp the tissue simulant 2-1. During this process, the first drive motor 0-2-21 applies a pulling force such that the tissue simulant 2-1 gradually changes from resting within the jaws 0-11 to sliding out of the jaws 0-11 until the entire tissue simulant 2-1 is completely pulled out of the jaws 0-11, and the test is complete.

It should be noted that controlling the opening and closing of the jaws 0-11 of the cutting assembly 0-1 is a function realized by the motor driving control of the stapler, and only needs to trigger the corresponding function switch on the cutting assembly 0-1 to control the opening of the jaws 0-11, and then control the closing of the jaws 0-11 after placing the tissue simulant 2-1.

In the application, the closing force and the clamping force which can be applied by the jaws 0-11 in the cutting assembly 0-1 of the anastomat when clamping human or animal tissues can be simply and effectively tested through the cooperation of the tissue simulator 2-1 and the clamping force testing assembly 2-2. Compared with the detection mode of artificial perception estimation in the prior art, the test device in the application has the advantage that the test result is more accurate.

Optionally, as shown in fig. 4, in another specific embodiment of the present application, the cutting member testing device may further include a tool bit testing member 2-4, and the tool bit testing member 2-4 may specifically include:

the tension sensors 2-41 are connected with one ends of the mounting rods 0-12, which are far away from the jaws, transmission gears are connected with the tension sensors 2-42, and a second motor is connected with the transmission gears; the tension sensors 2-42 can drive the blades in the jaws 0-11 to move along the axis of the mounting rods 0-12 via the drive gears to cut the tissue simulant 2-1.

A blade is arranged in a jaw 0-11 of a cutting assembly 0-1, when suturing, the blade needs to be pushed forwards to cut human or animal tissues, then the blade retracts, the human or animal tissues are clamped through the jaw 0-11, suturing nails are nailed into the tissues, and finally the purpose of suturing is achieved. The blade test assembly 2-4 is used to test whether the blades of the cutting assembly 0-1 are normally advanced to cut tissue and are normally retracted after cutting is complete.

In fig. 4, blade push rods 0-14 connected with the blades are arranged inside the mounting rods 0-12, and one ends of the blade push rods 0-14, which are far away from the blades, are sequentially connected with tension sensors 2-41, a transmission gear and a second motor. The tension sensors 2-41 are connected with the end part of the blade push rod 14 through a connecting piece with a buckle, so that falling-off is avoided. The transmission gear comprises a strip gear 2-42 and a circular gear 2-43, the second motor is connected with the circular gear 2-43 and drives the circular gear 2-43 to rotate, and the circular gear 2-43 rotates in different directions, so that the strip gear 2-42 can be driven to push forwards or pull the blade push rod 0-14 backwards, and the forward cutting and the backward retreating of the blade are realized.

The resistance of the blade in the forward cutting and backward retracting process can be measured based on the tension sensors 2-41 between the blade push rods 0-14 and the strip gears 2-42, and if the blade is not smooth in the forward cutting and backward retracting process, the tension sensors 2-41 can certainly measure the sudden resistance, so that whether the blade can smoothly advance or retract can be determined according to the force measured by the tension sensors 2-41. And the resistance when the blade is pushed forwards to cut can reflect the situation of the sharpness of the blade to a certain extent, which cannot be obtained by manual sensing detection in the prior art.

Optionally, in another specific embodiment of the present application, as shown in fig. 4 and 5, the cutting assembly testing apparatus 2 may further include:

rotating the test component 2-5 and the swing head test component 2-6;

the rotary testing component 2-5 comprises a ring gear 2-53 sleeved on the cutting component mounting rod 0-12, a driving gear 2-52 meshed with the gear structure of the ring gear 2-53, and a third driving motor 0-2-61 connected with the driving gear 2-52; the third driving motor 0-2-61 can drive the ring gear 2-53 to rotate around the axis by driving the gear 2-52;

the head swinging test assembly 2-6 comprises a transmission rod 2-62 connected with two steering pull rods 0-13 in the installation rods 0-12 and a fourth driving motor 0-2-61 connected with the two transmission rods 2-62; the fourth drive motor 0-2-61 can drive the two steering linkage rods 0-13 via the transmission rods 2-62 to move in opposite directions along the axis of the cutting assembly mounting rods 0-12.

As shown in FIG. 5, the mounting rods 0-12 include two segments, namely, a first mounting rod 0-121 and a second mounting rod 0-122, wherein the second mounting rod 0-122 is disposed between the first mounting rod 0-121 and the jaws 0-11, the first mounting rod 0-121 and the second mounting rod 0-122 are coaxially disposed and are relatively movable along the axis, and the second mounting rod 0-122 and the jaws 0-11 are fixedly connected, so that the second mounting rod 0-122 and the first mounting rod 0-121 are relatively rotated, and the stapler can be conveniently adjusted by a user in practical application of the stapler according to the direction of the jaws 0-11.

In order to test whether the first mounting rods 0-121 and the second mounting rods 0-122 can rotate relative to each other, the first mounting rods 0-121 are sleeved with the ring gears 2-53, the ring gears 2-53 are meshed with the driving gears 2-52, and the third driving motors 0-2-61 can control the driving gears 2-52 to rotate so as to drive the ring gears 2-53 to rotate. Because the ring gears 2-53 are fixedly sleeved on the first mounting rods 0-121, the ring gears 2-53 can rotate to drive the first mounting rods 0-121 to rotate; at the same time, the second mounting rods 0-122 are fixed to the bracket assembly 4 and cannot rotate, so that if the ring gears 2-53 can drive the first mounting rods 0-121 to rotate relative to the second mounting rods 0-122, the first mounting rods 0-121 and the second mounting rods 0-122 and the jaws 0-11 can rotate.

In fig. 4, two rotating pull rods 0-13 extend in the cutting assembly mounting rods 0-12 to connect the two sides of the ends of the jaws 0-11, and when the two rotating pull rods 0-13 move in opposite directions along the length direction, the jaws 0-11 are driven to swing in a direction perpendicular to the movement of the rotating pull rods 0-13.

In the embodiment, one end of each of the two rotating pull rods 0-13, which is far away from the corresponding jaw 0-11, is connected with one transmission rod 2-62, and the fourth driving motor 0-2-61 drives the two transmission rods 2-62 to drive the two rotating pull rods 0-13 to move in two opposite directions, so as to verify whether the test jaw 0-11 can swing.

Furthermore, the annular part is composed of two semicircular U-shaped clamps 2-32, one ends of the two U-shaped clamps 2-32 are hinged, and the other ends of the two U-shaped clamps 2-32 are connected through a locking structure 2-34, so that when the cutting component 0-1 to be tested needs to be replaced, the annular part can be rapidly opened through the locking structure and placed into the cutting component 0-1 to be tested, and after the cutting of one cutting component 0-1 is completed, the other cutting component 0-1 can be rapidly replaced through the locking structure 2-34.

The motor testing device in the integrated testing system of the stapler will be described in detail with specific embodiments.

In an alternative embodiment of the present application, as shown in fig. 7, fig. 7 is a schematic structural diagram of a motor testing apparatus provided in the embodiment of the present application, where the motor testing apparatus 3 includes:

In the actual test process, after the driving motor 0-2 is fixed through the motor support piece 3, an output shaft of the driving motor 0-2 is connected with the torque and rotation speed tester 3-2 through the coupler 3-5, and the torque and rotation speed tester 3-2 is connected with the magnetic powder brake 3-3 through the electric synchronizer 3-4. When the driving motor 0-2 operates under the action of the load force applied by the magnetic powder brake 3-3, the torque and rotating speed tester 3-2 can detect the rotating speed and the torque of the output shaft of the driving motor 0-2 in real time; the change rule of the rotating speed and the torque of the driving motor 0-2 along with time during test operation is approximately the same as the change rule of the rotating speed and the torque of the driving motor 0-2 along with time in practical application by adjusting the magnitude of the load force applied to the driving motor 0-2 by the magnetic powder brake 3-3; if the driving motors 0-2 can still normally operate in the test state, it is indicated that the driving performance of the driving motors 0-2 is good.

the central axes of the first connecting shaft 3-41 and the second connecting shaft 3-42 and of the synchronizing ring 3-44 coincide; when the electromagnet 65 is electrified, the shifting fork 3-45 can be driven to drive the synchronizing ring 3-44 to slide along the central shaft; the spacing between the two gear wheels 3-43 is smaller than the width of the synchronizing ring 3-44.

As shown in fig. 8, when the electromagnet 3-46 is not energized, the shift fork 3-45 and the synchronizing ring 3-44 are located on the side close to the first connecting shaft 3-41, and the serration structure on the inner ring of the synchronizing ring 3-44 and the gear 3-43 on the first connecting shaft 3-41 are engaged with each other, while the synchronizing ring 3-44 and the gear 3-43 on the second connecting shaft 3-42 are disconnected from each other;

when the synchronous electromagnets 3-46 are electrified, the shifting forks 3-45 can be driven by the magnetic field force of the synchronous electromagnets 3-46 to move along the central shafts of the synchronous rings 3-44 until the sawtooth structures on the inner rings of the synchronous rings 3-44 and the gears 3-43 on the second connecting shafts 3-42 are mutually sleeved and meshed, and then the magnetic powder brake 3-3 and the driving motor 0-2 can be connected. The shift fork 3-45 and the synchronizing ring 3-44 are connected by bearings, which are not shown in fig. 8.

In the embodiment, the connection or disconnection between the connecting shaft of the magnetic powder brake and the connecting shaft of the torque and rotation speed tester 3-2 is realized by controlling the electrification or the outage of the synchronous electromagnets 3-46, which is equivalent to the connection and the disconnection between the magnetic powder brake and the output shaft of the driving motor 0-2, so that the sudden change of the load force of the output shaft of the driving motor 0-2 is controlled, and the safety and the effectiveness of applying the load force to the output end of the driving motor 0-2 are ensured.

Alternatively, as shown in fig. 9; in another specific embodiment of the application, a voltage and current collector 3-7 is further connected between the control circuit board and the driving motor 0-2 and is used for collecting the voltage value and the current value of the driving motor 0-2;

the control circuit board is provided with a waveform generator 3-61, a comparator 3-62, a PID regulator 3-63, a first arithmetic unit 3-64, a second arithmetic unit 3-60, a first analog signal amplifying circuit 3-65, a second analog signal amplifying circuit 3-66, a third analog signal amplifier 3-69, a switch circuit 3-67 and a pulse signal conversion circuit 3-68; wherein, the waveform generator 3-61 is a device which is preset to generate the waveform of the rotation speed and the torque of the output shaft of the driving motor 0-2 along with the time change;

the input end of the first analog signal amplifying circuit 3-65 is connected with the torque signal output end of the torque and rotation speed tester 3-2, and the output end is connected with the input end of the first arithmetic unit 3-64;

the input end of the pulse signal conversion circuit 3-68 is connected with the rotating speed signal output end of the torque rotating speed tester 3-2, and the output end is connected with the input end of the first arithmetic unit 3-64;

the first input end of the comparator 3-62 is connected with the waveform generator 3-61, the second input end is connected with the first arithmetic unit 3-34, and the output end is connected with the PID regulator 3-63;

the first output ends of the PID regulators 3-63 are connected with the switching circuits 3-67, and the output ends of the switching circuits 3-67 are connected with the electric synchronizers 3-4; the second output end of the PID regulator 3-63 is connected with the second analog signal amplifier 3-66, and the output end of the second analog signal amplifier 3-66 is connected with the magnetic powder brake 3-3;

the first input terminals of the second operators 3-60 are connected to the output terminals of the first operators 3-64, and the second terminals are connected to the output terminals of the third analog signal amplifiers 3-69; the output end is connected with the output port of the control circuit board;

the input terminals of the third analog signal amplifiers 3-69 are connected to the output terminals of the voltage current collectors 3-7.

Referring to fig. 9, the first analog signal amplifying circuit 3-65 and the pulse signal converting circuit 3-68 in the control circuit board respectively receive the torque signal and the rotation speed signal detected by the torque and rotation speed tester 3-2; the torque signal is amplified by a first analog signal amplifying circuit 3-65 and then input to a first arithmetic unit 3-64, the torque signal converts an analog quantity signal into specific torque data by the first arithmetic unit 3-64, the rotating speed signal converts a pulse quantity into specific rotating speed data by the first arithmetic unit 3-64, and the torque data and the rotating speed data are output to a comparator 3-62.

Further, the waveform generators 3 to 61 are devices for generating waveforms of torque and rotation speed with time, which are artificially set according to the magnitude of load force to which the drive motors 0 to 2 are subjected in practical use. After the comparator 82 obtains the torque data and the rotational speed data during the test of the drive motors 0-2, then collecting the torque value and the rotating speed value in the waveform corresponding to the current moment in the waveform generator 3-61, and the torque value and the rotating speed value in the current waveform set in the waveform generator 3-61 are respectively compared with the torque data and the rotating speed data of the driving motor 0-2 measured and obtained by the torque and rotating speed tester 3-2, and outputs the comparison result to the PID regulator 3-63, if the torque value and the torque data are different or the rotating speed data are different, the PID regulator 3-63 regulates the load force output from the magnetic powder brake through the second analog amplifying circuit 3-66, thereby causing the torque and the rotational speed of the drive motors 0-2 to vary according to a waveform preset in the waveform generator 1.

In order to make the test condition of the driving motor 0-2 easier to judge and analyze, a voltage current collector is further adopted to collect voltage signals and current signals under the operation condition of the driving motor 0-2, the collected signals are input to a second arithmetic unit 3-60 through a third analog signal amplifier 3-69, the second arithmetic unit 3-60 converts analog quantity data of the voltage signals and the current signals into specific ground voltage values and current values and outputs the specific ground voltage values and current values through an output end of a control circuit board, and simultaneously, torque data and rotating speed data measured by a torque rotating speed tester 3-2 are also sent to the second arithmetic unit 3-60 and are output from an output end of the control circuit board through the second arithmetic unit 3-60.

Then, in practical application, a user can judge whether the test process of the driving motor 0-2 meets the requirements, whether the voltage and current of the driving motor 0-2 are over-current, whether the output power of the driving motor 0-2 is over-large, and the like through the torque data and the rotating speed data, and further judge whether the performance of the driving motor 0-2 is qualified.

Specifically, a display screen can be connected to the main control computer 1, so that data such as torque, rotating speed, voltage, current and the like output by the control circuit board can be visually displayed on the display screen, and a user can conveniently watch a test result.

It should be noted that the waveform generator, the PID regulator, the analog operational amplifier, the comparator and the first operator all belong to circuit devices that are relatively mature in application in the prior art, and the present application does not relate to improvements on specific devices, but only combines and integrates these devices on the control circuit board, which is in line with the protection object of the invention.

The control circuit in through the control scheme board realizes the feedback regulation to the load power of driving motor's output shaft in this application for the change condition of the load power when the change condition of the load power that driving motor's output received more is close actual application, is favorable to improving the validity to driving motor test.

Based on the above embodiment, as shown in fig. 10, fig. 10 is a schematic structural diagram of an electrical component testing apparatus provided in the embodiment of the present application, and the electrical component testing apparatus 4 may include:

a circuit board test assembly 4-1 for electrical connection with contact pins of a circuit board; a battery test assembly 4-2 for electrically connecting the positive and negative electrodes of the batteries 0-4; the main control test board is connected with the circuit board test component 4-1, the battery test component 4-2 and the main control machine 1;

the main control test board is used for collecting electric signals of contact pins of the circuit board through the circuit board test assembly 4-1, collecting positive and negative signals of the batteries 0-4 through the battery test assembly 4-2, and sending the electric signals and the positive and negative signals to the main control computer 1;

the circuit board testing component 4-1 and the battery testing component 4-3 are both provided in plurality.

It should be noted that, in practical application, the circuit board in the stapler needs to output corresponding electrical signals through contact pins connected with the components such as the driving motor 0-2, and further control the driving motor 0-2 to drive the cutting component 0-1 to work normally.

Therefore, when the circuit board is detected, only the fact that whether the electric signals output by the contact pins of the circuit board are the electric signals required by the operation of the 0-2 driving motor needs to be detected is needed, and the electric signals mainly refer to voltage signals.

For the batteries 0 to 4, only the output voltages and the output currents of the batteries 0 to 4 need to be measured, and the detection can be realized by a conventional multimeter generally. Therefore, no matter the detection of the electric signals of the circuit board or the detection of the voltage and the current of the batteries 0-4, the test can be directly carried out by adopting the test principle of the existing multimeter. Therefore, the main control test board in the application can directly adopt a test board integrated with a test circuit similar to a universal meter, and the test principle of the main control test board is the same as that of the universal meter. Since the detection principle of the multimeter is currently a well-known technology, the circuit structure and principle of the main control test board will not be described in detail herein.

Further, as shown in fig. 11, the circuit board testing component 4-1 may specifically include:

the thimble 4-11 is connected with the main control test board and is used for being electrically connected with a contact pin of the circuit board; the first electromagnetic push rod 4-12 is used for driving a start-stop tact switch on the circuit board to be switched on and off; a second electromagnetic push rod 4-13 for driving the stroke tact switch on the circuit board to be switched on and off; a servo motor push rod 4-14 connected with the main control test board and used for driving the stroke recognition mechanism on the circuit board; the supporting parts 4-15 are used for supporting and limiting the circuit board;

it should be noted that, for circuit boards, there are typically a plurality of contact pins, and the number of contact pins on the circuit board of the stapler is as many as 24. The effort for testing the circuit board is significantly increased if each contact pin of the circuit board is tested individually. Therefore, the ejector pins 4-11 with the same number as the electric contact pins on the circuit board can be arranged in the circuit board testing assembly, and the arrangement mode of the ejector pins 4-11 is the same as that of the contact pins on the circuit board. Each contact pin on the circuit board is connected to a corresponding one of the pins 4-11 when the circuit board is mounted on the support.

Meanwhile, the thimble 4-11 is electrically connected with the main control test board, that is, the main control test board is electrically connected with the contact pins of the circuit board, so that the main control test board can detect the electric signals of the contact pins of the circuit board.

For the circuit board of the stapler, its contact pins are capable of outputting electrical signals, generally because there is a corresponding control signal input to the circuit board. The circuit board of the anastomat is provided with a plurality of tact switches, the tact switches mainly comprise switch contacts and switch elastic sheets, and the switch elastic sheets and the switch contacts are mutually disconnected in a free state; when the switch elastic sheet is extruded and deformed to be closed with the switch contact, the contact pin of the circuit board can output a corresponding electric signal, and the driving motor performs corresponding work.

As for the circuit board of the anastomat, the tact switches thereof are mainly classified into two types:

one type is a start-stop tact switch, in the practical application of the anastomat, the switch elastic sheet is pressed by manually pressing a control button on the anastomat, so that the switch elastic sheet and the switch contact are contacted and closed, the start-stop tact switch is provided with two on a circuit board, one is used for controlling the blade of a cutting assembly of the anastomat to push and cut, and the other is used for controlling the reverse retraction of the blade.

There is another type of stroke control switch, that is, the stroke tact switch in the present embodiment, the number of the stroke tact switches is plural, and the specific number is determined by the number of different models of the cutting assembly of the stapler. After the circuit board is installed on the anastomat, when the cutting assemblies 0-1 of different models are installed on the anastomat, the stroke recognition mechanism on the circuit board is pushed to move, the moving distance is related to the size of the cutting assemblies 0-1, all the stroke tact switches share one switch contact, and the switch elastic sheet of one stroke tact switch can be closed to the switch contact and is related to the moving distance of the stroke recognition mechanism. When the switch contact is contacted and closed with the switch elastic sheets at different positions, the voltage output by the corresponding contact pins on the circuit board is different, and further the control that different cutting assemblies 0-1 can drive different cutting strokes is realized. For example, the cutting assembly 0-1 comprises three different types of blades with cutting strokes of 20mm, 40mm and 60mm, when the cutting assembly has a stroke of 20mm, the mounted cutting assembly can push the stroke recognition mechanism to a corresponding position, so that the stroke recognition mechanism drives the switch contact to reach a position where the switch contact can be closed with the spring plate of the light touch switch which is controlled to be 20mm, when the light touch spring plate is attached to the switch electric shock, the corresponding contact pin of the circuit board can output corresponding voltage to the driving motor 0-2, and the maximum cutting stroke of the blade of the cutting assembly 0-1 is 20 mm; by analogy, the circuit board can be controlled to drive the blade in different stroke ranges according to different cutting assemblies.

In order to better simulate the actual working process of the circuit board, in the embodiment, the circuit board testing assembly 4-1 is provided with the servo motor push rods 4-14 for simulating the cutting assembly 0-1 to push the stroke recognition mechanism, as shown in fig. 12, the servo motor push rods 4-14 can sequentially push the stroke recognition mechanism to be located at different positions respectively. Correspondingly, the switch contacts on the circuit boards 0-3 can be sequentially closed with switch elastic pieces corresponding to different stroke tact switches, so that the working state of the circuit boards 0-3 matched with cutting assemblies of different models can be tested.

Optionally, in a specific embodiment of the present application, each of the first electromagnetic push rod 4-12 and the second electromagnetic push rod 4-13 includes an electromagnet connected to the main control test board, and a push rod connected to an iron core of the electromagnet;

In the push rod of the first electromagnetic push rod 4-12 shown in fig. 11, when the electromagnet is in the power-on state, the iron core is acted by the magnetic field force to drive the push rod to move upwards, so that the switch elastic sheet is extruded, the switch elastic sheet is bent towards the switch contact, and finally the switch elastic sheet and the switch contact are in contact closure. Correspondingly, the corresponding electrical signals output by the contact pins of the circuit boards 0-3 can be detected, and if the electrical signals responding in time can be detected, the circuit boards 0-3 can work normally.

As shown in fig. 12, the pushing force of the first electromagnetic push rod 4-12 on the switch elastic sheet of the start-stop tact switch is in a vertical direction, that is, perpendicular to the plane of the circuit board 0-3. Unlike the first electromagnetic push rods 4-12, the push rod moving direction of the second electromagnetic push rods 4-13 is moving horizontally, i.e. parallel to the plane of the circuit boards 0-3. This is similar to the actual operation of the circuit boards 0-3, and for the stroke tact switch, the switch spring plate is contacted with the switch contact by the pushing force in the direction parallel to the surfaces of the circuit boards 0-3. Although the direction of the acting force of the second electromagnetic push rod 4-13 on the switch elastic sheet is different from the direction of the acting force of the first electromagnetic push rod 4-12, the working principles of the two electromagnetic push rods are completely the same, and therefore detailed description is omitted.

Based on the above discussion, it can be known that, for the main control test board, in addition to the need to detect the electrical signals of the circuit boards 0 to 3 and the battery, the main control test board needs to supply power to the servo motor push rods 4 to 14, the first electromagnetic push rods 4 to 12, and the second electromagnetic push rods 4 to 13, but this technical scheme can be implemented based on the existing technical scheme, that is, the main control test board capable of detecting the electrical signals and supplying power to the electromagnets and the motor is available in the prior art, and the main control test board is not an innovative point of the present application, but the key point is to connect the test board with this function with the circuit board test assembly 2, the battery test assembly 3, and other components, and to cooperate with each other to implement the test of the electrical devices of the anastomat.

Optionally, in another specific embodiment of the present application, the support 4-15 in the circuit board testing assembly 4-1 may specifically include:

support columns 4-151, side plates 4-152 and pressure plates 4-153;

wherein, the top ends of the supporting columns 4-151 can penetrate through the through holes of the circuit boards 0-3;

the side plates 4-152 and the supporting upright columns 4-151 are arranged in parallel, and the upper ends of the side plates are hinged with the pressing plates 4-153;

when the circuit boards 0-3 are placed on the support posts 4-151, the press plates 4-153 can be pressed against the surfaces of the circuit boards 0-3.

As shown in fig. 10 and 11, there are a plurality of through holes for the circuit boards 0-3 themselves, and accordingly, step posts having a size slightly smaller than that of the through holes for the circuit boards 0-3 may be provided at the upper ends of the support posts 4-151, so that the top ends of the support posts 4-151 may penetrate through the through holes for the circuit boards 0-3, thereby preventing the circuit boards 0-3 from moving in the horizontal plane.

Meanwhile, the side plates are arranged at the two sides of the circuit board, the side plates 4-152 at one side of the circuit board 0-3 are hinged with the pressing plates 4-153 in the drawing 12, when the pressing plates 4-153 are overturned and pressed on the surface of the circuit board 0-3, the pressing plates 4-153 can be buckled and connected with the side plates 4-152 at the other side, and then the pressing plates 4-153 limit the circuit board 0-3 from the vertical direction and limit the movement of the circuit board 0-3 in the vertical direction. Therefore, the support columns 4-151, the pressure plates 4-153 and the side plates 4-152 are matched to limit and fix the circuit boards 0-3, and the circuit boards 0-3 are prevented from moving in the test process.

Further, as shown in fig. 13 and 14, the battery test assembly 4-2 may include:

the battery testing component 4-2 comprises a limiting shell 4-21 with an opening at the upper end and used for arranging a battery; a gland 4-22 which is used for buckling on the upper end port of the limit shell 4-21 and forms a cavity for arranging the battery with the limit shell 4-21; the elastic contact piece 4-23 is arranged in the limit shell 4-21 and is used for being electrically connected with the anode and the cathode of the battery; and a temperature sensor disposed inside the limit housing 4-21.

As shown in fig. 13, a battery to be tested can be pressed in through an opening at the upper end of the limiting shell 4-21, and the limiting shell 4-21 is internally provided with an elastic contact 4-23, when the battery is pressed in the limiting shell 4-21, the elastic contact 4-23 is pressed, so that the battery is tightly contacted with the elastic contact 4-23, and the contact position is just the position of the positive and negative electrodes of the battery, that is, the elastic contact 4-23 is electrically connected with the positive and negative electrodes of the battery. As shown in fig. 14, after the battery is pressed into the limiting shell 4-21, the pressing cover 32 can be fastened at the upper opening of the limiting shell 4-21, and the battery is packaged and fixed in the cavity formed by the pressing cover 32 and the limiting shell 4-21; and the main control test board is electrically connected with the main control test board through the elastic contact pieces 4-23 to realize the measurement of the voltage and the current of the anode and the cathode of the battery.

The battery test assembly 4-2 also includes a temperature sensor disposed inside the positive housing 4-21. After the battery is pressed into the limiting shell 4-21, the temperature sensor can be just attached to the surface of the battery, and therefore the temperature of the battery can be detected.

This temperature sensor and main control test board all are connected with the main control computer to can send the data acquisition to the main control computer, the main control computer can audio-visually show the test result to the user on the display screen.

The main control computer is used for realizing basic functions of system setting, control, monitoring, recording, reporting and rechecking, can also be customized and developed according to an accessed device, sets corresponding functions in a page, and meets the functions of displaying, reporting, storing and summarizing test results and uploading.

The main control machine also has an identity authentication function, the identity authentication part of the main control machine allows the identity registered in the system to acquire the corresponding authority and function for operating the main control machine, and the identity authentication part allows 3 levels, user levels, administrator levels and maintenance engineer levels to be set. The user level allows the user to perform the basic functions of control, detection, logging, reporting and review of each test device after logging in. The administrator level can set user name and password, select working state of each device, select whether the device is in working state or maintenance state, and perform basic maintenance and calibration, checking, managing and cleaning of test records and reports, and the like. And a maintenance engineer can set and maintain the bottom layer operation of each testing device through a main control computer. The method can change the communication baud rate and the communication protocol, calibrate and optimize the measurement parameters, calibrate and correct the control parameters, add, modify and delete the report format, maintain the database, add and set the newly added function and the interface function of the device, and has the characteristic of flexible test.

Furthermore, because the test system may have a span in a spatial position, if the component testing device and the main control computer belong to different rooms, the main control computer performs the operation of the test process, so that the user can operate the component testing device alone, and the test data of the component testing device is uploaded when being queried by the main control computer, thereby completing the data transmission. The active inquiry strategy of the main control computer also ensures that the data transmission among the test devices does not conflict.

Specifically, the operation interface of the main control computer can be defined according to a testing device, the testing device has an equipment code and an address, and the testing device is favorable for realizing quick response and response reliability with the main control computer through the simple communication format and the handshake-plus-check transmission strategy.

After a communication link between the main control computer and the testing device is established, the information is transmitted in a master-slave mode, the main control computer actively inquires, and the inquiry content comprises whether a testing action exists or not, whether testing data exists or not after the testing action exists, whether transmission is finished or not in the uploading process of the testing data, and continuous uploading is not finished. The testing device displayed on the current operation interface monopolizes the data transmission channel, other testing devices only transmit events, after the testing interface of a certain testing device is activated, data of all events corresponding to the testing device are transmitted, if the testing interface is not activated all the time, the data are only recorded in the testing device, and the main control computer can select a testing item on the interface to conduct data testing.

The management, communication and scheduling among the test devices are realized by the active inquiry of the main control computer to the event and data of the test equipment for separate transmission, and the activation mark of the test interface determines whether to transmit the data. When no data is transmitted currently after the interface is activated, the recorded events can be recalled to realize uploading and displaying of the data, and when recall and test historical data conflicts with currently generated data, the conflict is solved according to the principle of priority of transmission starting time, which is a control decision made based on low frequency and long time of the test process of the test equipment. The engineer may create a new test set and set the name, model, address, baud rate, etc. of the test set. Before the testing device is connected with the main control machine, the identity authentication code is sent by the main control machine at regular time, and the identity authentication code comprises a device type, an equipment code and a secret key. After the connection is established, the master controller establishes an address for the master controller, and transmits information such as commands and data by taking the equipment code + address as a data packet header. The device code is typically a unique number that is fixed at the time of manufacture of the device. The communication format is preset, and the graphic display communication format is as follows: { device code } + { address } + { packet information } + { command } + { data } + { check }. In the example, the launch test button communication format is:

equipment code	Address	Packet information	Command	Data of	Verification
						0x45378266	0x08	0x0915	0x05	0x01	0x56DC
