Description

Technical Field

[0001] The invention relates to the field of withstand voltage testing equipment, and in particular to withstand voltage testing equipment for a Hall component. Background Art

[0002] Before conducting a withstand voltage test on electrical components, it is necessary to establish electrode conduction conditions for the electrical components. The existing technology usually uses tray stacking and direct contact of lifting and lowering pressure plates covered with electrode terminals to establish conduction. The test results are usually expressed in color indicator lights, and defective product screening needs to be completed with manual cooperation. Since the conduction is established by direct contact, during each direct contact process, the components stacked in the static tray cannot be absolutely centered, so the electrode terminals will be impacted by external forces of varying degrees and angles each time. On this basis, further affected by the positioning errors in the height and horizontal directions, a high false alarm rate will occur. The detection process needs to be repeated at least three times, and each repeated detection aggravates the problem of terminal misalignment. Summary of the invention

[0015] The technical solutions in the embodiments of the present invention are described clearly and completely below. 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.

[0016] like Figure 1-4As shown, the embodiment of the present invention includes:

[0017] A Hall component withstand voltage test device comprises a feed line 1, a floating carrier 2, a material cavity 3, a potential hole 4, a potential base station 5, a potential terminal 6, and a lifting and compressing plate 7. The feed line 1 is suspended with a floating carrier 2, the floating carrier 2 is provided with a plurality of material cavities 3, each material cavity 3 is provided with a plurality of potential holes 4, a potential base station 5 is provided along the feed line 1, a plurality of potential terminals 6 are provided on the potential base station 5, a lifting and compressing plate 7 is provided directly above the potential terminal 6, and the lifting and compressing plate 7 lowers the height of the floating carrier 2 so that the potential terminal 6 is synchronously connected to the potential hole 4.

[0018] Among them, the floating vehicle 2 is composed of a carrier plate 21, a flat-headed pin shaft 22, a spring 23, a guide column 24, and a guide sleeve 25. A guide sleeve 25 is vertically arranged on the feed line body 1, and a guide column 24 is arranged at the bottom of the carrier plate 21. The guide column 24 is matched and inserted in the guide sleeve 25. The carrier plate 21 is vertically and movably inserted with a flat-headed pin shaft 22. The lower end of the flat-headed pin shaft 22 is fixed on the feed line body 1. A spring 23 sleeved on the flat-headed pin shaft 22 is compressed and arranged between the carrier plate 21 and the feed line body 1. The spring 23 makes the floating vehicle 2 higher than the potential terminal 6.

[0019] Furthermore, the lifting and pressing plate 7 is suspended on a gantry 72 through a lifting cylinder 71, and a contour-profiling stopper 73 is provided on the lower surface of the lifting and pressing plate 7, and the contour-profiling stopper 73 corresponds to and matches the material cavity 3, and an optical fiber sensor 74 embedded in the contour-profiling stopper 73 is provided on the upper surface of the lifting and pressing plate 7. The optical fiber sensor 74 is used to sense the state of the Hall component, which can control the working condition of each withstand voltage detection circuit on the one hand, and identify and locate defective products according to the sorting number on the other hand.

[0020] Furthermore, the floating vehicle 2 and the potential base station 5 are provided with shaft sleeves 51 , the lifting and lowering plate 7 is provided with a positioning shaft 75 , and the shaft sleeves 51 correspond to and match the positioning shaft 75 .

[0021] Furthermore, the floating vehicle 2 is provided with a spacing adjustment pad 26. The spacing adjustment pad 26 matches the height of the contour-profiling stopper 73, so that the contour-profiling stopper 73 is matched in the material cavity 3 at a suitable height to prevent the Hall component from being crushed.

[0022] The feed line 1 comprises two parallel rails, each rail is provided with a base, each base is provided with a platform, the guide sleeve 25 is installed on the platform, a guide sleeve 25 is provided at each end of each platform, and a flat pin 22 is provided next to each guide sleeve 25. The floating vehicle 2 is rectangular in shape and the guide posts 24 are distributed at the four corners of the floating vehicle 2. The guide posts 24 and the flat pins 22 are symmetrically distributed so that the entire floating vehicle 2 is balanced on the spring 23.

[0023] The feed line 1 is directly driven by a straight line module, such as Figure 1 As shown, the floating vehicle 2 flows out of the potential base station 5. This state is used to realize material loading docking, and the assembled Hall components will be placed in the material hole 3. Under the periodic process rhythm matching condition, the floating vehicle 2 will be sent into the potential base station 5 by the feed line 1 in the full material state. Due to the elastic force of the spring 23, the floating vehicle 2 will be suspended above the potential base station 5, and all the potential terminals 6 on the potential base station 5 are electrically connected to the withstand voltage test equipment. Therefore, the test can be started after the floating vehicle 2 is in place and the pressure connection is implemented. Therefore, a pair of photoelectric sensors are arranged on both sides of the gantry 72. The height of the photoelectric sensor is equivalent to the height of the floating vehicle 2. After the floating vehicle 2 is in place, it is sensed by the photoelectric sensor, which triggers the downward movement of the lifting and lowering plate 7.

[0024] The crimping process is driven by the lifting cylinder 71, and the entire lower surface of the lifting and pressing plate 7 approaches the floating vehicle 2. During the approaching process, the positioning shaft 75 will be inserted into the two layers of shaft sleeves 51 for alignment, thereby ensuring that the potential base station 5, the floating vehicle 2, and the lifting and pressing plate 7 are aligned; then the profiling limit block 73 is loaded into the material hole 3, and the profiling limit block 73 clamps the Hall component in the material hole 3 to keep the Hall component stably placed and movable; the lifting cylinder 71 finally presses the lifting and pressing plate 7 against the floating vehicle 2 and further compresses the spring 23 to lower the height of the floating vehicle 2. After being lowered into place, the potential terminal 6 will be connected to the potential hole 4 and electrically connected to the Hall component in the potential hole 4.

[0025] To sum up, the present invention provides a Hall component withstand voltage test equipment. In order to solve the detection abnormality problem caused by the offset problem of traditional direct-touch detection equipment, a floating carrier 2 is used to establish a dynamic conduction interface, and the potential terminal 6 is fixedly integrated into the potential base station 5. At the same time, the positioning axis 75 is used to realize three-layer synchronous positioning, thereby effectively improving the conduction quality and extending the service life.
