Description

Technical Field

[0001] The utility model relates to the technical field of sensor detection equipment, in particular to a fixed-distance detection tooling for a magnetic sensor. Background Art

[0002] Reed switch is a special magnetic sensitive switch. It usually consists of two or three reed contacts made of both magnetic and conductive materials, which are encapsulated in a glass tube filled with inert gas or vacuum. The ends of the parallel reeds in the glass tube overlap and leave a certain gap or contact each other to form the normally open or normally closed contact of the switch; therefore, it is used as a sensor for counting, limit, etc.

[0003] After the reed switch is assembled, it needs to be inspected. In the prior art, workers usually hold a magnetic detection piece to approach the reed switch for inspection. This detection method is difficult to determine the trigger distance of the reed switch, resulting in a large error. Another method uses a screw to drive the magnetic detection piece close to the reed switch. Although this method has a small error and can determine the trigger distance of the reed switch, it has a complex structure and a slow detection speed. Therefore, there is an urgent need for a detection tool that can quickly detect whether the reed switch is qualified. Summary of the invention

[0021] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0022] First, combine Figure 1 The fixed-distance detection tooling of the magnetic sensor according to the embodiment of the utility model is described, which is used to perform fixed-distance detection of the triggered state / non-triggered state of the magnetic sensor 4 containing the reed switch, and judge the good and defective magnetic sensors 4, which has a wide range of application scenarios.

[0023] like Figure 1 As shown, the fixed distance detection tooling of the magnetic sensor of the embodiment of the utility model comprises a base 1 and a detection module;

[0024] Specifically, Figure 1As shown, the detection module is arranged on the base 1, and is used to judge the good and bad products of the magnetic sensor 4 according to the detection standard. The detection module comprises: a first card seat 21, a guide rail 22, a second card seat 23, a first limiter 24, a second limiter 25, an energized component and a display component; the first card seat 21 is arranged on the base 1, and is used to place the magnet; the guide rail 22 is arranged on the base 1; the second card seat 23 is slidably arranged on the guide rail 22, and the second card seat 23 is arranged relative to the first card seat 21, and is used to place the magnetic sensor 4 to be detected; the first limiter 24 is adjustable in position on the base 1, and is used to limit the stroke of the tail end of the second card seat 23; the second limiter 25 is adjustable in position on the base 1, and is used to limit the stroke of the head end of the second card seat 23; the energized component is arranged on the base 1, and the energized component is connected to the magnetic sensor 4 to be detected and the display component; the display component is used to display the detection result. In this embodiment, the first holder 21 and the second holder 23 can be adjusted according to needs. The first holder 21 is used to fix the magnetic sensor 4 to be detected, and the second holder 23 is used to fix the magnet.

[0025] Further, if Figure 1 As shown, the power-on component includes: a power-on interface 261, which is arranged on the base 1 and connected to the magnetic sensor 4 to be detected and the display component.

[0026] Further, if Figure 1 As shown, the display component includes: a display light 271, which is arranged on the base 1 and connected to the power-on component. The quality of the magnetic sensor 4 to be detected is judged by whether the display light 271 is on or off.

[0027] Furthermore, the fixed-distance detection tooling of the magnetic sensor of the embodiment of the utility model also includes: a pair of waist holes 3, the pair of waist holes 3 are opened on the base 1, and are located on both sides of the guide rail 22, the first limit member 24 and the second limit member 25 are respectively connected to the pair of waist holes 3 at both ends, the first limit member 24 and the second limit member 25 are both adjustable through the pair of waist holes 3. The position of the base 1 can be adjusted, so that the distance of the fixed-distance detection can be adjusted according to needs, and the application range is wider.

[0028] Further, if Figure 1 As shown, there may be multiple detection modules, which are arranged in parallel on the base 1, so that multiple detection personnel can perform detection at the same time, thereby improving detection efficiency.

[0029] When in use, first adjust the positions of the first limit member 24 and the second limit member 25 according to the specific distance of the trigger / non-trigger distance of the magnetic sensor 4 (the position of the first limit member 24 is the non-trigger position, and the position of the second limit member 25 is the trigger position), so as to indirectly adjust the limit points of the tail end and the head end of the second holder 23. After adjusting the positions of the first limit member 24 and the second limit member 25, place the magnetic sensor 4 to be detected on the second holder 23, connect the power-on end of the magnetic sensor 4 to be detected to the power-on interface 261, and place the corresponding magnet on the first holder 21, and then perform a two-step detection.

[0030] Step 1: Push the second card holder 23 to move toward the first card holder 21. When the head end of the second card holder 23 contacts the second stopper 25, if the indicator light 271 is off, it is a defective product. If it is on, it is a good product. The second step of testing is performed only when the first step is a good product.

[0031] Step 2: Move the second card holder 23 away from the first card holder 21. When the tail end of the second card holder 23 contacts the first stopper 24, if the indicator light 271 is still on, it is a defective product. If it is off, it is a good product. Only products that are good products after both steps are qualified products. Complete the detection of all magnetic sensors 4 in sequence according to the above steps.
