[0002] Thermistor is a sensor resistor whose resistance value changes with temperature. According to the temperature coefficient, it is divided into positive temperature coefficient thermistor and negative temperature coefficient thermistor. The resistance value of positive temperature coefficient thermistor increases with the increase of temperature, and the resistance value of negative temperature coefficient thermistor decreases with the increase of temperature.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figures 1 to 4 A comprehensive thermistor visual inspection device includes a mounting frame 1, a guide tube 102 is fixedly installed at the front end of the mounting frame 1 by bolts, and an observation tube 6 is fixedly installed at the front end of the mounting frame 1 by bolts. Specifically, the observation tube 6 is composed of four support rods and a tempered glass tube, so that the internal state can be observed without blind spots. The observation tube 6 is located below the guide tube 102 and is on the axis with the guide tube 102. An operating table 7 is fixedly installed at the front end of the mounting frame 1, and the operating table 7 is located below the observation tube 6. The upper end of the operating table 7 is detachably mounted with a magnifying glass 5 by means of bolts. The magnifying glass 5 can be composed of multiple lenses, so as to achieve more subtle observation. The end of the operating table 7 away from the magnifying glass 5 is fixedly mounted with a supporting tube 2. The front end of the mounting frame 1 is fixedly mounted with a stabilizing plate 301 by means of bolts. The outer surface of the stabilizing plate 301 is provided with a plurality of thermistors 11 to be detected, and a feeding device for clamping the thermistors 11 is provided in front of the stabilizing plate 301. The inner end of the guide tube 102 is slidably mounted with a movable cone tube 101. See also Figure 2 , 3, a movable tube 201 is slidably mounted on the inner end of the support tube 2, and a jet tube 204 for jetting gas is rotatably mounted on the right end of the movable tube 201. Specifically, a rectangular opening is provided at one end of the movable tube 201 close to the jet tube 204, and the jet tube 204 is located in the rectangular opening. The connection between the jet tube 204 and the movable tube 201 is clamped by a torsion spring. In order to achieve smoother airflow jetted by the jet tube 204, more specifically, a guide port 207 is fixedly welded on the inner end of the jet tube 204, and a plurality of holes are provided on the outer surface of the guide port 207, and the holes are spiral-shaped, so that the airflow can be ejected in a spiral shape, thereby blowing the thermistor 11 and suspending it in the air; A partition plate 209 is fixedly installed on the inner end of the movable tube 201, and a through hole is provided on the outer surface of the partition plate 209, and a stabilizing tube 210 is passed through the through hole, and an air pump 3 is fixedly installed on the bottom end of the support tube 2, and the output end of the air pump 3 is fixedly connected to the left end of the stabilizing tube 210 through an air inlet pipe 208. Specifically, a connecting tube 206 is slidably installed on the inner end of the stabilizing tube 210, and an air outlet nozzle is provided on the upper end of the connecting tube 206. More specifically, a rectangular bar is fixedly installed on the outer surface of the connecting tube 206, and a rectangular groove is provided on the inner end of the stabilizing tube 210. The rectangular bar is slidably installed in the rectangular groove, so as to prevent the connecting tube 206 from rotating during the left and right movement. The connecting tube 206 and the stabilizing tube 210 are connected by a return spring 205. A through hole is provided on one end of the injection tube 204 close to the stabilizing tube 210, and the connecting tube 206 moves toward the injection tube 204 and passes through the through hole, and then the air outlet nozzle at the upper end of the connecting tube 206 is located inside the injection tube 204; Specifically, a driving motor 203 is fixedly installed on the upper end of the support tube 2, and a screw 202 is fixedly installed on the output shaft of the driving motor 203, and a sleeve is fixedly installed on the upper end of the movable tube 201, and the sleeve is sleeved on the outer surface of the screw 202. When the output end of the driving motor 203 drives the screw 202 to rotate, the movable tube 201 is driven to move left or right through the sleeve, and the injection tube 204 is in a vertical state with the movable tube 201 under the action of the torsion spring. When the movable tube 201 moves in the direction away from the support tube 2, the injection tube 204 collides with the inner wall of the support tube 2 to achieve parallelism between the injection tube 204 and the movable tube 201.

[0020] Example 2: Please refer to Figure 4 , 5, a comprehensive thermistor visual inspection device, based on embodiment 1, a stabilizing rod 103 is fixedly installed at one end of the mounting frame 1 close to the movable cone tube 101, the stabilizing rod 103 and the movable cone tube 101 are on the same axis, and a through hole is opened at the upper end of the movable cone tube 101, and the bottom end of the stabilizing rod 103 is located inside the movable cone tube 101 after passing through the through hole, and the movable cone tube 101 is connected with the stabilizing rod 103 by a feeding spring 107, and the elastic force of the feeding spring 107 makes the movable cone tube 101 always maintain an upward movement force, and an air outlet 108 is fixedly installed at the upper end of the guide tube 102, and the movable cone tube 101 is located inside the air outlet 108. When the high-speed airflow passes through the outer surface of the movable cone tube 101, according to the principle that the higher the airflow, the lower the pressure, the air flow rate on the outer surface of the movable cone tube 101 is fast, while the air at the upper end of the movable cone tube 101 is relatively still, thereby realizing that the movable cone tube 101 moves downward at the same time as the high-speed airflow blown out by the injection pipe 204.

[0021] like Figure 1 , 4 As shown in Figure 5, a strip inlet is provided at the right end of the movable cone tube 101, and a pouring plate 104 is arranged in the strip inlet. The pouring plate 104 is fixedly welded to the movable cone tube 101. Specifically, the pouring plate 104 is tilted. Rectangular openings are provided at the left and right ends of the movable cone tube 101, and intercepting rods 105 are arranged in the rectangular openings. The intercepting rod 105 is rotatably connected to the movable cone tube 101, and an abutment block 106 is fixedly installed at the inner end of the guide tube 102. When the thermistor 11 reaches the inside of the movable cone tube 101, the intercepting rod 105 intercepts the thermistor 11. When the intercepting rod 105 reaches the abutment block 106, it is squeezed by the abutment block 106, and then the intercepting rod 105 starts to rotate. Finally, the ends of the intercepting rods 105 that are close to each other start to move away from each other, and then the thermistor 11 falls under the action of its own gravity.

[0022] Specifically, a controller (not shown in the figure) is fixedly installed on the upper end of the operating table 7. The controller is a PID controller, and the model is OmronE5CC, Eurotherm3216, etc. The controller is electrically connected to the air pump 3 through a signal line. The inside of the observation tube 6 is detachably installed with a photoelectric sensor through bolts for detecting the current position of the thermistor 11. The model is KeyencePZ-G42N, OmronE3Z series, and a pressure sensor is fixedly installed on the inner end of the injection tube 204 for detecting the air pressure of the injection tube 204. The model is SMCISE30A, Honeywell26PC series. Then the controller needs to know the suspension height of the thermistor 11 in the observation tube 6 and feed it back to the controller for adjustment. Then it is necessary to use a laser distance sensor for real-time monitoring. The laser distance sensor is fixedly installed on the inner bottom end of the observation tube 6, and the laser distance sensor model is KeyenceIL series, SICKODMini series.

[0023] The thermistor 11 first falls naturally into the observation tube 6 in the movable cone 101. When the photoelectric sensor detects that the thermistor 11 reaches the specified position, the controller controls the output of the air pump 3 to realize the blowing of the injection pipe 204. The air pressure is monitored by the pressure sensor and adjusted by the controller to ensure that the thermistor 11 is suspended at the specified height. Then the laser ranging sensor measures the height of the thermistor 11 in real time and feeds the data back to the PID controller. The PID controller adjusts the air pressure sprayed from the injection pipe 204 according to the measured value and the set target height to ensure that the thermistor 11 is stably suspended.

[0024] The forces on the thermistor 11 during suspension mainly include gravity and aerodynamic force generated by the blowing of the jet pipe 204. In order to stabilize the thermistor 11 in suspension, these two forces need to be balanced:

[0025] in, is the jet tube 204, m is the mass of thermistor 11, and g is the acceleration due to gravity (9.81 m / s²); The high-speed gas blown out of the injection pipe 204 is approximately expressed by the following formula:

[0026] in, is the resistance coefficient of the airflow, A is the windward area of ​​the thermistor 11, is the air density, v is the air velocity, and the air pressure is adjusted to control the air velocity v. Thereby controlling the suspension height; The PID controller is used to adjust the air flow velocity v to maintain the thermistor 11 at a specified height. , the output of the PID controller (control signal ) can be expressed as:

[0027] in, is the error between the target height and the actual height, , , , are the proportional, integral and differential coefficients of the PID controller respectively, is the control signal, which is used to adjust the air pressure of the airgun, thereby changing the airflow velocity v. It is worth noting that all the above calculations are calculated by the processor inside the controller; like Figure 6 , 7 As shown, the feeding device includes a chain 302, and the chain 302 is tensioned and sleeved on the outer surface of the stabilizing plate 301. Specifically, a material changing motor 303 is fixedly installed on the upper end of the stabilizing plate 301, and stabilizing wheels are rotatably installed on the left and right ends of the stabilizing plate 301. The chain 302 is sleeved on the outer surfaces of the two driving wheels, and the output shaft of the material changing motor 303 is fixedly connected to the left stabilizing wheel. The output end of the material changing motor 303 drives the driving wheel to rotate, and then when the driving wheel rotates, it drives the chain 302 to rotate on the outer surface of the stabilizing plate 301, and a fixed block 304 is fixedly installed on the bottom end of the chain 302, and a movable block 308 is rotatably installed on the end of the fixed block 304 away from the chain 302, and the thermistor 11 is located between the fixed block 304 and the movable block 308.

[0028] A tilting rod 305 is rotatably installed at the upper end of the chain 302, and a top block 307 is rotatably installed at one end of the tilting rod 305 close to the movable block 308. The top block 307 is sleeved on the outer surface of the contact at the upper end of the thermistor 11. Specifically, a rectangular hole is opened at the center of the chain 302, and an abutment plate 306 is provided below the rectangular hole. The right end of the tilting rod 305 passes through the rectangular hole and is fixedly connected to the abutment plate 306. More specifically, when the pouring plate 104 moves upward, the top end of the pouring plate 104 contacts the bottom end of the abutment plate 306 and pushes the abutment plate 306 to move upward.

[0029] like Figure 2 , 8 A discharge pipe 4 is fixedly installed at the bottom end of the support cylinder 2, and the discharge pipe 4 and the support cylinder 2 are on the same axis. A fork plate 12 is fixedly installed at the inner end of the discharge pipe 4, which guides the discharge pipe 4 to the unqualified area and the qualified area respectively. A switching plate 13 is rotatably installed at the inner end of the discharge pipe 4, and a handle for easy grasping is fixedly installed on the upper end of the switching plate 13, so as to manually change the direction of the switching plate 13 at any time.

[0030] The working principle of the present invention is: When in use, the material changing motor 303 is started to drive the driving wheel to rotate, thereby allowing the chain 302 to rotate on the outer surface of the stabilizing plate 301, and the thermistor 11 to be detected is driven by the material changing motor 303 to come to the top of the pouring plate 104. At this time, the air pump 3 no longer blows air, so that the movable cone tube 101 moves upward under the action of the return spring 205, and then the pouring plate 104 is inserted between two adjacent thermistors 11, so that the left thermistor 11 is offset under the slope of the pouring plate 104, and then the upper end of the pouring plate 104 contacts the lower end of the abutment sheet 306, so that the abutment sheet 306 moves upward, and through the rotation of the tilting rod 305, the top block 307 is no longer in contact with the upper end contact of the thermistor 11, and then the thermistor 11 also slides into the movable cone tube 101; Then the controller drives the air pump 3 to start working, and then the air flow is ejected from the injection pipe 204, and then the movable cone tube 101 moves downward under the action of air pressure, and when the interception rod 105 reaches the abutment block 106, it is squeezed by the abutment block 106, and then the interception rod 105 starts to rotate, and finally the ends of the interception rods 105 that are close to each other start to move away from each other, and then the thermistor 11 falls under the action of its own gravity; When the thermistor 11 reaches the inside of the observation tube 6, it is suspended under the action of the airflow. The operator then uses the magnifying glass 5 to observe whether the appearance of the thermistor 11 is qualified. After the observation, the handle is turned to change the direction of the switch plate 13. The output shaft of the driving motor 203 drives the screw 202 to rotate, and drives the movable tube 201 to move left or right through the sleeve. The injection tube 204 is in a vertical state with the movable tube 201 under the action of the torsion spring. When the movable tube 201 moves away from the support tube 2, the injection tube 204 collides with the inner wall of the support tube 2 to make the injection tube 204 parallel to the movable tube 201. The air inlet 208 stops blowing. Without the blowing of the airflow, the thermistor 11 also falls to the discharge tube 4 and finally enters the designated area.

[0031] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto.
