DETAILED DESCRIPTION

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0030] See also Figure 1-6The present embodiment provides a semi-automatic sensor testing tool, including a detection component 1, a fixing component 2 and a power-on component 3. The fixing component 2 includes a fixing housing 201, and the fixing housing 201 is provided with a fixing groove. The width of the fixing groove is the same as the width of the sensor. The structure of the sensor is described here. Two copper bars 6 are arranged at one end of the sensor of the present solution. The two copper bars 6 are symmetrically arranged at both sides of one end of the sensor. A plurality of pins 7 are arranged at the other end of the sensor at equal intervals. The length of the fixing groove is less than the length of the sensor. The detection component 1 and the power-on component 3 are respectively arranged at the two ends of the fixed shell 201. The power-on component 3 includes a power-on cylinder 301, a power supply and a copper block. The copper block is arranged at the output end of the power-on cylinder 301. The power supply is electrically connected to the copper block, and the copper block can lock or release its fitting relationship with the copper bus 6 of the sensor; the detection component 1 includes a detection cylinder 105 and a plurality of detection probes 5. The plurality of probes and the pins 7 of the plurality of sensors are matched one by one. One end of any probe is connected to the output end of the detection cylinder 105, and the other end thereof can lock or release its fitting relationship with the corresponding pin 7 of the sensor. By providing the power supply component 3 and the detection component 1, when the sensor is manually placed on the fixed shell 201, the power supply cylinder 301 starts to work, so that the copper block and the copper bar 6 of the sensor are fitted together, so that the pin 7 of the sensor has current. When the output end of the detection cylinder 105 is extended to make the detection probe 5 and the pin 7 of the sensor fit together, whether the sensor can work normally can be judged by whether the detection probe 5 can detect the current on the pin 7 of the sensor. In addition, since the present solution only limits the movement of the sensor by the fixing groove opened on the fixed shell 201, and since the width of the fixing groove is the same as the width of the sensor, and the length of the fixing groove is less than the length of the sensor, the fixed shell of the present solution The matching accuracy of the housing 201 to the sensor is low, which makes it convenient for manual placement of the sensor directly on the fixing groove of the fixed housing 201, reducing the time for placing the sensor on the fixture, thereby improving the speed and efficiency of sensor detection, and solving the problem that the existing detection devices for sensors are all provided with a fixture for fixing the sensor to ensure that the sensor does not move during the detection process. However, in order to ensure that the detection device can accurately detect the pin 7 of the sensor, the matching accuracy between the fixture for fixing the sensor and the sensor is improved. However, such a setting also increases the difficulty of manually placing the sensor on the fixture, thereby increasing the time for placing the sensor on the fixture, and reducing the speed and efficiency of sensor detection.

[0031] Specifically, the energizing component 3 of the present scheme also includes an insulating block 304 and a limiting block 305. The insulating block 304 is connected to the output end of the energizing cylinder 301, the copper block is arranged on the insulating block 304, and the limiting block 305 is arranged on the top of the insulating block 304. The bottom surface height of the limiting block 305 is the same as the top surface height of the sensor, and the limiting block 305 can lock or release its fitting relationship with the sensor; by providing the insulating block 304, it can be prevented that the current from the copper block will flow to the energizing cylinder 301, thereby causing damage to the energizing cylinder 301; in addition, by providing the limiting block 305 in the present scheme, when the copper block is fitted with the copper bus 6 of the sensor, the limiting block 305 will move to the top of the sensor, and the bottom surface of the limiting block 305 and the top surface of the sensor are arranged to fit each other, further limiting the movement of the sensor.

[0032] Specifically, the copper blocks of the present solution include a positive copper level block 302 and a negative copper level block 303. The positive and negative electrodes of the power supply are respectively connected to the positive copper level block 302 and the negative copper level block 303. The positive copper level block 302 and the negative copper level block 303 are respectively matched with the two copper bars 6 of the sensor one by one. The copper bar 6 of any sensor can lock or release its fitting relationship with the corresponding positive copper level block 302 or negative copper level block 303. Through such a setting, it is ensured that the two copper bars 6 of the sensor are powered on normally. In addition, the positive copper level block 302 and the negative copper level block 303 are respectively arranged on the insulating block 304, and the end face of the positive copper level block 302 close to the copper bus 6 and the end face of the negative copper level block 303 close to the copper bus 6 are on the same vertical plane. The purpose of such arrangement is twofold. On the one hand, the end face of the positive copper level block 302 and the end face of the negative copper level block 303 are flush with each other, which can ensure that the sensor can move along the central axis direction of the fixed groove until the copper bus 6 of the sensor is fitted with the end face of the fixed shell 201; on the other hand, when the copper bus 6 of the sensor is just manufactured, it is not necessarily arranged perpendicular to the sensor, but the copper bus 6 is inclined at a certain angle relative to the sensor. After the positive copper level block 302 and the negative copper level block 303 respectively push the corresponding copper bus 6 to fit the end face of the fixed shell 201, the copper bus 6 that was originally inclined relative to the sensor becomes perpendicular to the sensor, so that the copper block can correct the position of the copper bus 6 of the sensor.

[0033] Specifically, the detection assembly 1 of this solution also includes a connection block 101, a connection rod 102 and a fitting block 103. The connection block 101 is connected to the output end of the detection cylinder 105, and the fitting block 103 is connected to the connection block 101 in parallel. The two ends of the connection rod 102 are respectively connected to the connection block 101 and the fitting block 103. The fitting block 103 is provided with a plurality of non-overlapping circular holes 1031. The plurality of circular holes 1031 and the plurality of detection probes 5 are matched one by one. One end of any detection probe 5 is connected to the connection block 101, and the other end thereof passes through the corresponding circular hole 1031 to lock or release the fitting relationship between it and the sensor pin 7. Through such a setting, the normal operation of the detection probe 5 is ensured.

[0034] In addition, under ideal conditions, the pin 7 of the sensor should also be set vertically at one end of the sensor. However, in actual situations, the pin 7 of the sensor may be set tilted relative to the sensor. Since the inclination angles of the pins 7 of each sensor relative to the sensor are different, and the lengths of each detection probe 5 are the same, this will cause some detection probes 5 to fail to detect the pins 7 of the corresponding sensors. Based on this, before the detection probe 5 detects the pins 7 of the corresponding sensors, it is necessary to ensure that each pin 7 is in the same plane, that is, to ensure that each pin 7 is set vertically at one end of the sensor. The detection assembly 1 of the present solution also includes a driving unit 4 and a correction block 104. A sliding groove is provided at one end of the fixed housing 201 close to the detection probe 5. The correction block 104 can be slidably arranged in the sliding groove. The two ends of the driving unit 4 are respectively connected to the correction block 104 and the bonding block 103. The driving unit 4 is used to control the distance between the bonding block 103 and the correction block 104. Through such a setting, when the bonding block 103 slides toward the pin 7 close to the sensor due to the detection cylinder 105, the two ends of the driving unit 4 are respectively connected to the correction block 104. 04 is connected to the bonding block 103, so that the bonding block 103 controls the driving unit 4 to move, and the driving unit 4 controls the correction block 104 to move, so that the correction block 104 and the bonding block 103 are simultaneously moved toward the direction of the pin 7 close to the sensor, until the spacing between the correction block 104 and the bonding block 103 is equal to the thickness of the pin 7. At this time, the pins 7 with inconsistent inclination angles relative to the sensor will be clamped together by the bonding block 103 and the correction block 104, so that each pin 7 is vertically arranged at one end of the sensor.

[0035] Specifically, the driving unit 4 of the present solution includes a driving rack 401, a driving gear 402 and a driven rack 403. The driving gear 402 is rotatably arranged next to the fixed shell 201. One end of the driving rack 401 is connected to the bonding block 103, and the other end thereof is meshed with the driving gear 402. The fixed shell 201 is provided with a connecting groove, and the connecting groove and the sliding groove are interconnected. One end of the driven rack 403 is connected to the correction block 104 by passing through the connecting groove, and the other end of the driven rack 403 is meshed with the driving gear 402. Through such an arrangement, it can be realized that when the bonding block 103 moves toward the direction of the pin 7 close to the sensor, During movement, the driving rack 401 connected to the bonding block 103 controls the driving gear 402 to rotate, and then the driving gear 402 controls the driven rack 403 to engage and connect, so that the driven rack 403 slides, and then the correction block 104 connected to the driven rack 403 is controlled to move in the direction of the pin 7 close to the sensor, so that the bonding block 103 and the correction block 104 jointly clamp the pin 7 of the sensor; similarly, when the bonding block 103 moves in the direction away from the pin 7 of the sensor, the correction block 104 also moves in the direction away from the pin 7 of the sensor.

[0036] It should be noted that in order to ensure the normal operation of the device, the distance between the correction block 104 and the pin 7 of the sensor is equal to the distance between the bonding block 103 and the pin 7 of the sensor, and the spacing between the correction block 104 and the bonding block 103 is equal to the thickness of the pin 7 of the sensor, the correction block 104 and the bonding block 103 are respectively bonded to the two end faces of the pin 7 of the sensor.

[0037] In the above embodiment, since the distance between the fitting block 103 and the pin 7 of the sensor is constantly changing, in order to ensure that the detection probe 5 can smoothly detect the pin 7 of the sensor. Therefore, the detection probe 5 of this solution needs to have a telescopic structure. Based on this, the detection probe 5 of this solution includes a hollow detection shell 501, a detection spring 502 and a detection needle 503. The detection shell 501 is coaxially arranged in the corresponding circular hole 1031. One end of the detection shell 501 is fitted with the connection block 101, and the open end of the detection shell 501 is coaxially connected to the detection needle 503. The detection spring 502 is arranged in the detection shell 501, and the two ends of the detection spring 502 are respectively connected to the detection needle 503 and the detection shell 503. 01 connection; through such a setting, in the process of the fitting block 103 moving toward the pin 7 close to the sensor, the detection needle 503 is first fitted with the pin 7 of the sensor. Since the pins 7 of each sensor are not necessarily kept in the same plane at this time, based on this, the fitting block 103 will continue to move toward the pin 7 close to the sensor until the distance between the fitting block 103 and the correction block 104 is equal to the thickness of the pin 7 of the sensor. During this period, the detection needle 503 always maintains its fitting setting with the pin 7 of the sensor.

[0038] In addition, in order to ensure the setting strength of the detection shell 501, the end face of the detection shell 501 of the present scheme close to the fitting block 103 is located in the circular hole 1031. Such a setting can ensure that when the fitting block 103 is fitted with the pin 7 of the sensor, the detection needle 503 can be retracted into the detection shell 501, and the detection needle 503 can also maintain its fitting setting with the pin 7 of the sensor.

[0039] In order to ensure the normal operation of the detection needle 503, an empty groove 1032 is opened at one end of the bonding block 103 close to the pin 7 of the sensor. The area of ​​the empty groove 1032 wraps the area of ​​the circular hole 1031, and the height dimension of the empty groove 1032 is smaller than the height dimension of the pin 7 of the sensor projected on the end face of the bonding block 103. Such a setting will not affect the bonding block 103 and the correction block 104 to jointly correct the pin 7 of the sensor perpendicular to one end of the sensor, and at the same time, it can ensure that when the bonding block 103 is bonded to the pin 7 of the sensor, the detection needle 503 can still normally detect the pin 7 of the sensor.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
