[0002] The sensor controls the switch action by sensing the distance between an object and itself, so as to realize a non-contact switch. The sensor can be applied to the home field, such as an automatic door switch sensor, an automatic lighting switch sensor, a urinal sensor, etc. Taking the urinal sensor as an example, the urinal sensor sends a signal to a solenoid valve to automatically control flushing by sensing that a human body is within the sensing range. The sensing distance of the sensor is an important parameter, and corresponding tests need to be carried out before the sensor is assembled to ensure that the sensor can operate normally after being assembled into the product. At present, the test process of the sensor is as follows: after the sensor is fixed, the sensing baffle is moved closer to the sensor so that the sensing baffle moves to the sensing area of the sensor to test whether the sensor operates normally. However, due to the differences in the installation positions of the sensors of different types of products, the sensing distance of the sensor changes due to the installation angle of the sensor, resulting in the inability of the existing sensor test device to accurately test the sensor.

After locking the locking member to fix the tooling, the moving mechanism moves closer to or away from the tooling, and then tests the sensor, making the test of the sensor more similar to the situation of the sensor assembling to sense an object on the actual product, which helps to improve the accuracy of the sensor test.

[0015] As a further improvement of the above technical solution, the cooperation between the arc-shaped hole and the locking member enables the rotation angle of the tooling relative to the horizontal plane to be less than or equal to a preset angle.

[0016] As a further improvement of the above technical solution, the locking member switches positions between the two ends of the arc-shaped hole to enable the rotation angle of the tooling relative to the horizontal plane to switch between a first angle and a second angle.

[0026] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it should not be construed as a limitation on the protection scope of the present utility model.

[0027] In the description of the present utility model, it should be understood that for the orientation description, such as the orientation or positional relationship indicated by up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the drawings, and it is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it should not be construed as a limitation on the present utility model.

[0028] In the description of the present utility model, if there are descriptions with words such as "several", its meaning is one or more, and the meaning of multiple is two or more. Understanding greater than, less than, exceeding, etc. does not include the present number, and understanding above, below, within, etc. includes the present number.

[0029] In the description of the present utility model, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meaning of the above words in the present utility model in combination with the specific content of the technical solution.

[0030] In the related art, the sensor controls the switch action by sensing the distance between the object and itself to achieve a contactless switch. The sensing distance of the sensor is an important parameter, and corresponding tests need to be carried out before the sensor is assembled to ensure that the sensor can operate normally after being assembled into the product.

[0031] The sensor can be applied to the home field, such as automatic door switch sensors, automatic lighting switch sensors, urinal sensors, etc. Taking the urinal sensor as an example, the urinal sensor sends a signal to the solenoid valve to automatically control flushing by sensing that a human body is within the sensing range. Among them, the installation angle of the urinal sensor can be adjusted according to requirements during installation. For example, the urinal sensor can be tilted downward relative to the horizontal plane.

[0032] Currently, the test process of the sensor is as follows: After the sensor is fixed, the sensing baffle is moved and approached to the sensor to make the sensing baffle move to the sensing area of the sensor to test whether the sensor operates normally. However, due to the differences in the installation positions of the sensors of different types of products, the sensing distance of the sensor changes due to the installation angle of the sensor, and it is impossible to determine whether the sensing baffle moves into the sensing area of the sensor.

[0033] Based on this, the embodiment of the present utility model provides a sensor test device, which makes the test of the sensor more approximate to the situation where the sensor senses an object after being assembled into an actual product, and helps to improve the accuracy of the sensor test. Refer to Figures 1 to 2 , the following embodiments are made for the sensor test device of the present utility model:

[0034] The sensor test device includes a base 100, a base 200, a tooling 300, a moving mechanism 400, a baffle 500, and a locking member.

[0035] The base 200 and the moving mechanism 400 are both installed on the base 100. The tooling 300 is hinged to the base 200, and the tooling 300 rotates relative to the base 200. The baffle 500 is connected to the moving mechanism 400, and the moving mechanism 400 drives the baffle 500 to reciprocate to make the baffle 500 approach or move away from the tooling 300.

[0036] For example, the tooling 300 can rotate around an axis extending in the horizontal direction, and the tooling can also rotate around an axis extending in the vertical direction.

[0037] The locking member connects the base 200 and the tooling 300. Locking the locking member fixes the position of the tooling 300, and further fixes the angle of the tooling 300 relative to the baffle 500. Loosening the locking member allows the tooling 300 to rotate to change the angle of the tooling 300 relative to the baffle 500.

[0038] The tooling 300 is used to fix sensors such as sensors. The rotation of the tooling 300 can drive the sensor to rotate, so that the angle of the sensor relative to the baffle 500 changes. By using the baffle 500 to simulate an object or a human body approaching the sensor, the installation angle of the sensor can be made more in line with the situation of installing the sensor on the actual product.

[0039] After fixing the sensor to the tooling 300, according to the angle of the sensor on the product, loosen the locking member to change the angle of the tooling 300 relative to the base 200, so that the angle between the sensor on the tooling 300 and the baffle 500 more accurately matches the actual installation angle of the sensor. After locking the locking member to fix the tooling 300, the moving mechanism 400 approaches or moves away from the tooling 300, and then tests the sensor, which helps to improve the accuracy of the sensor test.

[0040] In this embodiment, there are various forms of the locking member. For example, a plurality of pin holes are provided on the outer side wall of the tooling 300, and the plurality of pin holes are arranged in sequence along the rotation direction of the tooling 300. A through hole is provided on the side wall of the base 200, and the locking member is a pin. The pin passes through the through hole and is inserted into any one of the pin holes to fix the tooling 300; when the angle of the tooling 300 needs to be changed, take out the pin, rotate the tooling 300 so that the appropriate pin hole faces the through hole, and then insert the pin into the pin hole. Or, a rotating shaft is provided on the outer wall of the tooling 300, and a through shaft hole is provided on the side wall of the base 200. The rotating shaft and the shaft hole cooperate to make the tooling 300 rotate relative to the base 200. A threaded hole is provided on the axis of the rotating shaft, and the locking member is a screw. The screw is screwed into the threaded hole, and the head of the screw abuts against the outer wall of the base 200. The position of the tooling 300 is fixed by the friction between the head of the screw and the outer wall of the base 200.

[0041] In this embodiment, there are various ways for the moving mechanism 400 to drive the baffle 500 to move reciprocally. For example, the moving mechanism 400 is a lead screw-nut transmission mechanism. The nut is connected to the baffle 500. The baffle 500 is slidably connected to the base 100. The nut is sleeved on the lead screw. Rotating the lead screw makes the nut rotate along the axis of the lead screw, and then drives the baffle 500 to move. Or, the moving mechanism 400 is a pneumatic push rod. The push rod is connected to the baffle 500. Compressed air is used to push the push rod to extend or retract to realize the reciprocating movement of the baffle 500. Or, the moving mechanism 400 is a gear-rack mechanism. The rack is connected to the baffle 500. The baffle 500 is slidably connected to the base 100. The gear is connected to the motor. The gear meshes with the rack, and the motor drives the gear to rotate to make the rack drive the baffle 500 to move.

[0042] After fixing the sensor to the tooling 300, according to the angle of the sensor on the product, loosen the locking member to change the angle of the tooling 300 relative to the base 200, so that the angle between the sensor on the tooling 300 and the baffle 500 more accurately matches the actual installation angle of the sensor. After locking the locking member to fix the tooling 300, the moving mechanism 400 moves closer to or away from the tooling 300, and then tests the sensor, making the test of the sensor more approximate to the situation of the sensor assembling to the actual product to sense an object, which helps to improve the accuracy of the sensor test.

[0043] In some embodiments, the moving mechanism 400 drives the baffle 500 to reciprocate in the front-rear direction, and the tooling 300 rotates around an axis extending in the left-right direction. The rotating shaft of the tooling 300 is perpendicular to the moving track of the baffle 500.

[0044] The rotation axis of the sensor is generally parallel to the horizontal plane, so that the sensor can adjust the included angle relative to the horizontal plane; when the sensor is installed on the actual product, the sensor forms an included angle relative to the horizontal plane, so as to facilitate the sensor to accurately face the user of the product. For example, for the sensor of an automatic faucet, the sensor is installed at the bottom of the faucet, and the sensor is inclined downward relative to the horizontal plane, so that when the user's hand reaches below the faucet, the sensor can recognize the user's hand and control the faucet to open the water valve.

[0045] In some embodiments, the baffle 500 moves in the front-rear direction, the tooling 300 rotates around an axis extending in the left-right direction, and through holes 210 are respectively provided on the left and right side walls of the base 200. The center of the arc of the through holes 210 is set on the rotation axis of the tooling 300, and the locking member passes through the through holes 210 to connect the tooling 300, and the angle of the tooling 300 is fixed by the friction force between the locking member and the outer side wall of the base 200.

[0046] After loosening the locking member, the tooling 300 can adjust the angle along the through holes 210 to realize that the tooling 300 drives the sensor to change the angle at will.

[0047] In some embodiments, the rotation angle of the tooling 300 is limited by the movement stroke of the locking member in the through holes 210, so that the angle between the tooling 300 and the horizontal plane is less than or equal to a preset angle, and the preset angle can be set according to the actual installation scenario of the sensor.

[0048] In some embodiments, since the locking member is inserted into the through holes 210, after loosening the locking member, the tooling 300 can drive the locking member to slide along the through holes 210. When the locking member moves to the first end and the second end of the through holes 210, the rotation angle of the tooling 300 relative to the horizontal plane is fixed to a first angle and a second angle, so as to facilitate the tooling 300 to switch between the accurate first angle and the second angle.

[0049] The tooling 300 can quickly switch between the first angle and the second angle, so that the tooling 300 can be adapted to two types of sensors, and the first angle and the second angle can be set according to the requirements of the sensors.

[0050] In some embodiments, the rotation angle of the tooling 300 relative to the horizontal plane is less than 15°, that is, the preset angle is 15°. The first angle is between 0° and 1°, and the second angle is between 12° and 14°. In this embodiment, the first angle is 0° and the second angle is 13°.

[0051] The angle between the tooling 300 and the horizontal plane switches between 0° and 13°, so that the tooling 300 can be adapted to sensors with installation angles between 0° and 13°.

[0052] In some embodiments, the tooling 300 includes a fixing member 310 and a movable member 320. The fixing member 310 is hinged to the base 200, and the movable member 320 is detachably connected to the fixing member 310. The sensor is installed on the movable member 320.

[0053] After adjusting the accurate angle through the fixing member 310 first, then install the sensor on the movable member 320, and finally assemble the movable member 320 to the fixing member 310, so that the installation angle of the sensor can be quickly determined, which helps to improve the testing efficiency of the sensor.

[0054] In some embodiments, a mounting hole 311 is provided at the top of the fixing member 310, the movable member 320 is inserted into the mounting hole 311, and the outer side wall of the movable member 320 abuts against the inner side wall of the mounting hole 311 to achieve fixation.

[0055] The movable member 320 is inserted into the mounting hole 311, making the assembly and disassembly operations of the movable member 320 and the fixing member 310 more convenient, and further improving the testing efficiency of the sensor.

[0056] In some embodiments, after the outer side wall of the movable member 320 abuts against the inner side wall of the mounting hole 311, the degree of freedom of the movable member 320 to rotate around the vertical axis is restricted.

[0057] Prevent the rotation of the movable member 320 relative to the fixing member 310 from causing the installation angle of the sensor to shift.

[0058] In some embodiments, the base 200, the tooling 300, the moving mechanism 400, the baffle 500, and the locking member form a testing unit, and a plurality of testing units are arranged side by side in the left - right direction on the base 100.

[0059] Using the device can test multiple single - eyes, which helps to improve the testing efficiency of the sensor.

[0060] Specifically, referring to Figures 1 to 2As shown, the inductor testing device includes a base 100 and multiple testing units. Each testing unit includes a base 200, a tooling 300, a moving mechanism 400, a baffle 500, and a locking member. The multiple testing units are arranged in sequence in the left - right direction on the base 100.

[0061] Taking any one of the testing units as an example, both the base 200 and the moving mechanism 400 are installed on the base 100. The bottom of the base 200 is connected to the base 100. Side plates extending upward are respectively provided on the left and right sides of the base 200. Each side plate is provided with an axial hole penetrating in the left - right direction, and each side plate is further provided with an arc - shaped hole 210 penetrating in the left - right direction. The center of the arc - shaped hole 210 coincides with the axis of the axial hole.

[0062] The tooling 300 includes a fixing member 310 and a movable member 320. Rotating shafts extending outward are provided on the left and right side walls of the fixing member 310. The rotating shafts are respectively inserted into the axial holes of the two side plates of the base 200, enabling the fixing member 310 to rotate around the axis of the rotating shaft.

[0063] A threaded hole is provided on the outer side wall of the fixing member 310. The position of the threaded hole corresponds to the position of the arc - shaped hole 210. When the fixing member 310 rotates relative to the base 200, the threaded hole moves along the arc - shaped hole 210. The locking member is a screw. After the screw passes through the arc - shaped hole 210, it is screwed into the threaded hole. Tightening the locking member makes the head of the screw abut against the outer side wall of the base 200, and the fixing member 310 is fixed by the friction force between the head of the screw and the outer side wall of the base 200.

[0064] An installation hole 311 is provided at the top of the fixing member 310. Limiting grooves penetrating upward are provided on the left and right side walls of the installation hole 311. Limiting blocks are respectively provided on the left and right side walls of the movable member 320. The movable member 320 is inserted into the installation hole 311, and the limiting blocks are inserted into the limiting grooves, enabling the movable member 320 to be installed on the fixing member 310.

[0065] An assembly hole for installing an inductor is provided at the top of the movable member 320.

[0066] The moving mechanism 400 includes a slide rail, a lead screw, a nut, and a motor. The motor is fixed to the base 100. The slide rail extends in the front - rear direction and is installed on the base 100. The slide rail is located in front of the base 200. The motor is connected to the lead screw. The nut is sleeved on the lead screw. The baffle 500 is slidably connected to the slide rail. The nut is connected to the baffle 500. Starting the motor makes the lead screw rotate, and then the nut drives the baffle 500 to move. By controlling the forward and reverse rotation of the motor, the forward and backward reciprocating movement of the baffle 500 is realized.

[0067] When testing the sensor, a plurality of sensors are installed one by one on a plurality of test units. Taking a certain test unit as an example, after the sensor is fixed to the tooling 300, according to the angle of the sensor on the product, the locking member is loosened to change the angle of the tooling 300 relative to the base 200, so that the angle between the sensor on the tooling 300 and the baffle 500 more accurately matches the actual installation angle of the sensor. After the locking member is tightened to fix the tooling 300, the moving mechanism 400 approaches or moves away from the tooling 300, and then the sensor is tested.

[0068] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the described embodiments.
