Description

Technical Field

[0001] The invention relates to the technical field of thermistor performance testing, and in particular to a thermistor temperature control testing device. Background Art

[0002] As a key component in the temperature control circuit, the thermistor is placed in an environment where the temperature needs to be controlled. When the temperature changes, the resistance of the thermistor changes, which in turn affects the current or voltage in the circuit to achieve temperature control.

[0003] The finished thermistor needs to be tested for its performance. The thermistor is placed in an environment where the temperature can be precisely controlled (such as a constant temperature water bath) to measure its resistance value. In the prior art, when measuring the resistance value of a thermistor, the operator needs to first clamp the pins of the thermistor with the crocodile clips of a multimeter, and then insert the thermistor into the constant temperature water bath. When measuring multiple thermistors at the same time, the operator needs to use the crocodile clips to clamp the pins of the thermistor one by one, and then release them one by one after the test is completed. This is time-consuming and labor-intensive. It will take a lot of time to test multiple groups of thermistors. In addition, when testing the resistance value of a group of thermistors at different temperatures, the temperature of the constant temperature water bath needs to be continuously adjusted. It will also take a certain amount of time to wait for the temperature of the constant temperature water bath to be adjusted, which affects the efficiency of the temperature control test of the thermistor.

[0043] In combination with the above embodiments, the entire working process and working principle of the above embodiments are as follows:

[0044] The initial state is:

[0045] The motor 208 is not energized, the rotating shaft 202 is not rotating, the two rotating seats 203 at the highest point on the rotating shaft 202 are flush, the two constant temperature water baths 204 at the highest point are flush, the hollow sleeve 210 is in an extended state, the cross bar 211 is located at the topmost point in the groove of the groove rod 401, the electric telescopic rod 302 is not contracted, the thermistor is not inserted in the jack 304, the driven gear 310 is not in contact with the rack 311, the rotating clamp 213 is opened under the action of the torsion spring, the reset spring 314 is in an extended state, the triangular block 313 extends out of the slide slot 312, the swing rod 402 is in a horizontal state, the pin shaft 1 405 is located at the topmost point in the limit slot 2 404, and the pin shaft 2 407 is located at the highest point in the groove of the groove wheel 406.

[0046] The working status is:

[0047] Insert the thermistor:

[0048] When the temperature control of the thermistor is detected, the two pins of the thermistor are aligned with a group of sockets 304, that is, two adjacent sockets 304. At this time, the reset spring 314 is extended, and the triangular block 313 extends to the outside of the slide groove 312. The upper inclined surfaces of the two triangular blocks 313 and the arc surface of the socket 304 form holes for fixing the pins of the thermistor, so that after the pins of the thermistor are respectively inserted into the two sockets 304, the thermistor is fixed.

[0049] Clip the thermistor pins:

[0050] After all the thermistors to be tested are inserted into the jacks 304, the electric telescopic rod 302 is started and retracted, driving the mobile frame 303 to move toward the cross bar 211, thereby driving the thermistor close to the cross bar 211. When the pins of the thermistor enter between the fixed clamp 212 and the rotating clamp 213, the rack 311 contacts the driven gear 310 under the drive of the electric telescopic rod 302, and drives the driven gear 310 to rotate, thereby driving the threaded barrel 306 to rotate. The rotation of the threaded barrel 306 causes the screws 307 on both sides to move toward the inside of the threaded barrel 306, thereby driving the two rotating seats. 308 moves in the direction of the threaded barrel 306, so that the two rotating seats 308 gradually move upward in the limiting groove 309, driving the top ends of the two rotating clamps 213 to approach the threaded barrel 306, so that the bottom ends of the rotating clamps 213 with teeth approach the teeth of the fixed clamp 212, gradually clamping the pins of the thermistor, thereby achieving the effect of automatically clamping the pins of the thermistor. Compared with the prior art in which technicians use alligator clips to clamp the pins of thermistors one by one, the present invention can clamp the pins of multiple thermistors at one time and connect them to the multimeter without the need for technicians to operate one by one, saving time and effort.

[0051] Rotating constant temperature water bath:

[0052] When the pins of the thermistor are clamped by the fixed clamp 212 and the rotating clamp 213, the motor 208 is started to drive the rotating shaft 202 to rotate, so that the rotating shaft 202 drives the rotating seat 203 and the fixed gear 205 to rotate at the same time. When the rotating shaft 202 drives the constant temperature water bath 204 to make a circular motion through the rotating seat 203, the rotating gear 207 coaxially fixedly connected to the constant temperature water bath 204 rotates synchronously under the action of the fixed gear 205 and the ring gear 206, so that when the six constant temperature water baths 204 make a circular motion with the rotating shaft 202 as the center, the six constant temperature water baths 204 are rotated under the action of the rotating gear 207. By rotating downward, the opening of the constant temperature water bath 204 is kept vertically upward while the constant temperature water bath 204 rotates with the rotating shaft 202 as the center, so as to prevent the constant temperature water bath 204 from tilting and spilling water. Compared with the prior art method of using a single constant temperature water bath 204 and gradually adjusting the temperature of the constant temperature water bath 204 to test the temperature control of the thermistor at different temperatures, six constant temperature water baths 204 can be used at a time and set to different temperatures. When it is necessary to test the temperature control of the thermistor at different temperatures, it is only necessary to use the motor 208 to drive the rotating shaft 202 to rotate and rotate the required constant temperature water bath 204 to be directly above the rotating shaft 202.

[0053] Insert the thermistor into the constant temperature water bath:

[0054] When the motor 208 drives the rotating shaft 202 to rotate the constant temperature water bath 204 to the top of the rotating shaft 202, the rotating shaft 202 drives the groove wheel 406 to rotate synchronously, so that the pin 2 407 moves to the middle of the groove wheel 406 under the action of the hexagonal star groove of the groove wheel 406, thereby driving the connecting rod 408 to move downward, so that the pin 1 405 pulls the pin 1 405 to move downward. At this time, the cross bar 211 is extended by the spring telescopic rod 209. When the pin 1 405 is pulled downward, the swing rod 402 and the pin 1 405 rotate first. Under the cooperation of the pin 1 405 and the arc segment of the limiting groove 2 404, the swing rod 402 first drives the cross bar 211 to rotate 90 degrees, and drives the fixed clip 212 and the rotating clip 213 on the cross bar 211 to rotate 90 degrees, and rotates the thermistor clamped in the fixed clip 212 and the rotating clip 213 to a vertical downward state. When the resistor rotates downward, the pin will push the inclined surface of the triangular block 313, so that the triangular block 313 slides into the slide groove 312, and then the connecting rod 408 further pulls the pin shaft 1 405 to move downward, so that the pin shaft 1 405 enters the vertical section of the limiting groove 204 and moves downward, thereby driving the cross bar 211 to squeeze the hollow sleeve 210 and the spring telescopic rod 209, so that the spring telescopic rod 209 contracts, and then the pin shaft 1 405 continues to slide downward in the limiting groove 204 under the action of the connecting rod 408, driving the cross bar 211 rotated ninety degrees to move downward, thereby inserting the thermistor clamped in the fixed clamp 212 and the rotating clamp 213 into the constant temperature water bath 204 for temperature control testing, so as to achieve the effect of automatically rotating the thermistor to vertically downward and inserting it into the constant temperature water bath 204 during the rotation of the constant temperature water bath 204, without the operator having to put the thermistors into the constant temperature water bath 204 one by one, which is more time-saving and labor-saving.

[0055] Automatically avoid the constant temperature water bath 204:

[0056] When the test of a constant temperature water bath 204 is completed and a constant temperature water bath 204 with different water temperature needs to be switched for testing, the thermistor is still inserted into the constant temperature water bath 204, and the motor 208 is started again to drive the rotating shaft 202 to rotate, so that the rotating seat 203 drives the constant temperature water bath 204 to rotate, and the fixed gear 205 and the groove wheel 406 rotate at the same time. When the groove wheel 406 rotates, the pin shaft 207 gradually slides into the corner of the hexagonal star groove again, so that The second pin 407 pushes the connecting rod 408 to slide upward, so that the connecting rod 408 pushes the top pin 1 405 to move upward. At this time, the pin 1 405 is located in the vertical section of the second limit slot 404. The pin 1 405 slides upward and drives the cross bar 211 to slide upward through the swing rod 402, thereby bringing the thermistor clamped in the fixed clamp 212 and the rotating clamp 213 out of the constant temperature water bath 204. When the pin 1 405 moves to the highest point of the vertical section of the second limit slot 404, When thermistor 211 is in the state of being moved back to the top of slot 401, cross bar 211 moves to the top of slot bar 401, so that cross bar 211 cannot continue to rise, and the thermistor rises out of constant temperature water bath 204. Subsequently, pin shaft 1 405 enters the arc section of limit slot 2 404 under the push of connecting rod 408, thereby driving cross bar 211 to rotate through swing rod 402 until cross bar 211 rotates ninety degrees to reset, and then drives the thermistor back to the socket 304 through fixing clamp 212 and rotating clamp 213. In this process, the thermistor pin squeezes the inclined surface of triangular block 313, so that triangular block 313 slides into slide slot 312 and squeezes reset spring 314. When the thermistor pin returns to the top of the socket 304, triangular block 313 pops out under the action of reset spring 314, and fixes the thermistor pin again, so as to realize the temperature control effect of thermistor at different temperatures tested by constant temperature water bath 204 of multiple temperatures at one time, and further improve the efficiency of thermistor testing.

[0057] Unplug the thermistor:

[0058] After the test is completed, the electric telescopic rod 302 extends and resets, driving the mobile frame 303 to move in the direction away from the cross bar 211, so that the rack 311 drives the driven gear 310 to rotate in the opposite direction, so that the threaded cylinder 306 is pushed out in the opposite direction to the screw rod 307, and then, with the cooperation of the rotating seat 308 and the limiting groove 1 309, the top end of the rotating clamp 213 is rotated toward the fixed clamp 212, and the bottom end is away from the fixed clamp 212, thereby releasing the clamping of the thermistor pins, and then the mobile frame 303 drives the thermistor to move in the direction away from the cross bar 211. After the thermistor pins leave between the fixed clamp 212 and the rotating clamp 213, the thermistor can be pulled out from the mobile frame 303. Compared with the test process in the prior art, there is no need to loosen the alligator clips one by one, which further saves the time of the thermistor temperature control test and improves the efficiency of the thermistor temperature control test.
