Description

Technical Field

[0001] This utility model belongs to the field of Hall current sensor technology and relates to a positioning device for processing Hall sensors. Background Technology

[0002] A Hall current sensor is a current detection sensor based on the Hall effect. A Hall current sensor includes a housing, inside which an induction coil and corresponding electronic circuitry are housed. During manufacturing, after the induction coil and electronic circuitry are installed in the housing, they need to be encapsulated with potting compound.

[0003] Current automated packaging systems mostly employ robotic arm-based dispensing equipment. Multiple sensors are evenly distributed beneath the robotic arm, which moves the dispensing gun to dispense adhesive one by one. In automated production, the cumulative error caused by differences in sensor placement can lead to a misalignment of the dispensing gun's position, affecting dispensing accuracy.

[0013] Electrode points are fixedly installed at both ends of the placement plate and at the end of the positioning plate near the placement plate. When the placement plate moves to the positioning plate, the electrode points are in contact. The wires of the two electrode points on the placement plate are connected.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 4 This utility model discloses a positioning device for processing Hall effect sensors, comprising a traveling rail 1 and a driving component 3. The traveling rail 1 includes two parallel tracks, and a placement plate 2 is slidably mounted on top of the traveling rail 1. The driving component 3 includes a chain 31 that passes through the traveling rail 1, with sprockets 32 at both ends of the chain 31. The sprockets 32 are connected to a drive motor 33, and the chain 31 is connected to the placement plate 2. Positioning rods 41 are fixedly mounted on both sides of the traveling rail 1, and positioning plates 42 are rotatably mounted on the positioning rods 41. One end of the positioning plate 42 extends to the traveling rail. At the upper end of the track 1, a positioning rod 41 is fixedly installed with a positioning drive 43. The output end of the positioning drive 43 abuts against the end of the positioning plate 42 away from the traveling track 1. Electrode points 5 are fixedly installed at both ends of the placement plate 2 and the end of the positioning plate 42 near the placement plate 2. When the placement plate 2 moves to the positioning plate 42, the electrode points 5 are in contact, and the wires of the two electrode points 5 on the placement plate 2 are connected. The electrode points 5 of the positioning plate 42 are connected to the drive motor 33 and the positioning drive 43. A shaped groove plate 6 is detachably installed on the upper end of the placement plate 2. The shaped groove plate 6 has multiple placement slots for mounting the sensors.

[0030] Specifically, rotatable positioning plates 42 are arranged on both sides of the travel rail 1, and electrode points 5 are set on the positioning plates 42 and the placement plate 2. When the placement plate 2 moves to the positioning plate 42, the electrode points 5 come into contact, making the two electrode points 5 on the positioning plate 42 conductive. The conductive signal is transmitted to the drive motor 33 and the positioning drive 43, causing the drive component 3 to stop running. After the glue is poured, the output end of the positioning drive 43 moves away from the positioning plate 42, and the drive motor 33 drives the placement plate 2 to the next process.

[0031] In this way, by setting the positioning plate 42 and the positioning drive 43, the stopping position of the placement plate 2 is limited, and the electrode point 5 is used to connect and control the travel rail 1 to stop running until the glue is poured. This makes the placement plate 2 stop at the position of the positioning plate 42, reducing errors and making the glue pouring position more accurate.

[0032] In some feasible methods, the travel rail 1 is a rectangular tube, and a strip groove is opened at the upper end of the travel rail 1 to pass through the travel rail 1. The chain 31 is connected to the placement plate 2 through the strip groove. The placement plate 2 is a rectangular plate, and the placement plate 2 is bolted to the groove plate 6. The groove plate 6 has a placement groove adapted for sensor installation. The Hall current sensor has different shapes and specifications and needs to be adapted to different placement grooves. By setting a detachable groove plate 6, it is easy to replace it as needed.

[0033] The positioning rod 41 is cylindrical, the positioning plate 42 is rectangular, and the electrode point 5 can be a metal sheet. The two electrode points 5 on the positioning plate 42 are connected to the controller of the drive motor 33 and the positioning drive 43 through wires. The controller outputs current to one of the electrode points 5 of the positioning plate 42. When the controller senses that the other electrode point 5 of the positioning plate 42 is at a high level, it performs preset logic control on the drive motor 33 and the positioning drive 43.

[0034] For better connection of electrode point 5, please refer to [link / reference]. Figure 3 The electrode point 5 includes an electrode sheet 51 and a spring-loaded pin connector 52. The electrode sheet 51 is disposed on the positioning plate 42, and the spring-loaded pin connector 52 is disposed on the placement plate 2.

[0035] As a specific embodiment of the positioning device for processing Hall sensor provided in the application, please refer to Figure 4. A chain 31 is fixedly installed with a plurality of connecting pieces 311, and a relief spring 34 is fixedly connected to the connecting pieces 311. The placement plate 2 is connected to the relief spring 34.

[0036] Overall, by setting the avoidance spring 34, after the placement plate 2 contacts the positioning plate 42, the chain 31 continues to move forward a certain distance. By stretching the avoidance spring 34, there is a certain amount of compression between the placement plate 2 and the positioning plate 42. On the one hand, it is convenient for the electrode point 5 to contact, and on the other hand, it is convenient for the placement plate 2 to stay in the set position, thus improving the positioning accuracy.

[0037] Furthermore, the positioning spring 34 is fixedly connected to the insertion tube 341, and the bottom of the placement plate 2 is fixedly installed with the insertion rod 342, which is inserted into the insertion tube 341.

[0038] It should be understood that in automated production, the chain 31 runs in a cycle. By setting up the placement plate 2 for plug-in installation, when the placement plate 2 runs to both ends of the travel rail 1, it is transferred to the next process by automated equipment such as a robotic arm, or transferred from the previous process to the glue dispensing process, which facilitates the automated operation of the equipment.

[0039] In some feasible ways, the connecting piece 311 is fixedly installed on one of the links of the chain 31. In order to avoid the position of the insertion tube 341 being unfavorable for insertion and installation, a permanent magnet is provided at the bottom of the insertion tube 341 so that the insertion tube 341 is attracted to the link, while not affecting the function of the avoidance spring 34.

[0040] As another specific embodiment of the positioning device for processing Hall sensor provided in the application, please refer to Figure 2 The positioning rod 41 is fixedly installed with the limit block 44, and a reset torsion spring is provided between the positioning plate 42 and the positioning rod 41.

[0041] It should be understood that by setting the limit block 44 and the reset torsion spring, the positioning plate 42 can be accurately reset after the placement plate 2 has passed.

[0042] In some feasible embodiments, the limiting block 44 includes two arc-shaped blocks fixedly installed on the positioning rod 41 and the positioning plate 42. The arc-shaped blocks on the positioning plate 42 rotate around the positioning rod 41 following the positioning plate 42, and stop after fitting against the arc-shaped blocks of the positioning rod 41. To facilitate limiting the position of the positioning plate 42, the positioning drive 43 is an electric actuator. The reset torsion spring is a common torsion spring, which is sleeved on the positioning rod 41, with its two ends fixed to the positioning rod 41 and the positioning plate 42 respectively.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
