Abstract
Description
Technical Field
[0001] This utility model relates to the field of dielectric capacitance sensor welding technology, and in particular to a dielectric capacitance sensor that is easy to position during welding. Background Technology
[0002] Dielectric capacitance sensors are based on the principle of capacitance sensing and are widely used in industrial inspection, electronic equipment, and automation control. Their structural accuracy and installation stability directly affect their detection performance. During production, they often require welding to connect with other components; therefore, the accuracy of welding positioning, ease of operation, and flexibility in troubleshooting are crucial for improving production efficiency and product yield.
[0003] Dielectric capacitance sensors require specialized tooling to ensure positioning accuracy during welding operations. For example, patent document CN220838636U discloses a dielectric capacitance sensor that facilitates welding positioning. This device integrates a dielectric capacitance sensor welding mechanism and a dielectric capacitance sensor removal mechanism. Although it can achieve synchronous welding positioning and batch removal of multiple sensors, its removal mechanism has design limitations. When a single sensor fails to weld, the entire dielectric capacitance sensor welding mechanism must be pressed down to complete the removal of all sensors. On the one hand, it is impossible to remove a single sensor that has failed to weld individually and quickly, resulting in insufficient operational flexibility and potential delays in subsequent repair welding or replacement processes. To solve the above problems, this utility model proposes a dielectric capacitance sensor that facilitates welding positioning. Utility Model Content

[0023] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.
[0024] This utility model provides a technical solution:
[0025] Please see Figures 1-6 A dielectric capacitance sensor for easy welding positioning includes: a tooling base plate 1 and a welding placement plate 2. Two limiting rods 5 are fixedly connected to the upper end of the tooling base plate 1, and a support seat 6 is slidably connected to the limiting rods 5. Multiple placement slots 4 are opened on the upper end of the welding placement plate 2. Multiple positioning posts 3 and multiple vertical rods 7 are fixedly connected to the upper end of the tooling base plate 1. The vertical rods 7 limit the welding placement plate 2, so that the welding placement plate 2 can only move vertically.
[0026] The placement slot 4 is equipped with a mounting mechanism for installing sensors. The mounting mechanism includes a limiting block 9 and a first spring 11 disposed within the placement slot 4. A fixing block 8 is fixedly connected to the bottom of the placement slot 4. A first connecting plate 10 and a second connecting plate 12 are fixedly connected to both ends of the first spring 11, respectively. Two openings are provided at the lower end of the welding placement plate 2. A mounting shaft 14 is provided on the inner wall of the placement slot 4. A push-out rod 13 is rotatably connected to the side wall of the mounting shaft 14. The push-out rod 13... Figure 4 As shown, it includes not only the vertical parts but also the inclined parts.
[0027] The mounting shaft 14 is connected to the ejector rod 13 via a connecting mechanism. The connecting mechanism includes a mounting ring 16 fixedly connected to the side wall of the mounting shaft 14. The side wall of the mounting ring 16 is elastically connected to the side wall of the ejector rod 13 via a second spring 15. The connecting mechanism elastically connects the mounting shaft 14 and the ejector rod 13 via the mounting ring 16 and the second spring 15. On the one hand, after the ejector rod 13 is pressed, the elastic restoring force of the second spring 15 can be used to make the ejector rod 13 quickly return to its initial position, ensuring the reliability of subsequent repeated use. On the other hand, the elastic connection can buffer the impact force when the ejector rod 13 rotates, avoiding hard damage to the sensor or placement slot 4 during the ejection process, thus balancing operational safety and structural durability.
[0028] Furthermore, the first connecting plate 10 has multiple first bolts on its side wall, and the second connecting plate 12 has multiple second bolts on its side wall, so that the first spring 11 can be disassembled and replaced if the first spring 11 loses its elasticity.
[0029] Furthermore, two third connecting discs 17 are fixedly connected to the side wall of the mounting shaft 14. The side wall of the third connecting disc 17 is provided with multiple third bolts, which allows the mounting shaft 14 to be disassembled and facilitates the replacement of the second spring 15 that has lost its elasticity.
[0030] Furthermore, the limiting rod 5 has an inverted U-shaped cross section, which can prevent the support seat 6 from moving off the limiting rod 5, so that it can only slide on the limiting rod 5. The support seat 6 has an L-shaped cross section, and the vertical part of the support seat 6 can play a positioning role in the position of the support seat 6 under the welding placement plate 2.
[0031] Furthermore, the side wall of the fixing block 8 is provided with a through groove 18. When the user's finger presses the upper end of the ejector rod 13, the through groove 18 on the side wall of the fixing block 8 can accommodate the finger, making the ejector rod 13 rotate more smoothly. The side wall of the limiting block 9 is provided with an inclined surface, so that the sensor can be placed more smoothly in the placement groove 4 after pressing down on the inclined surface of the limiting block 9.
[0032] In practical use, the working principle of this utility model is as follows:
[0033] Before the welding operation of the dielectric capacitance sensor begins, the operator can place the dielectric capacitance sensors to be welded one by one into the multiple placement slots 4 on the upper end of the welding placement plate 2. During the placement process, the lower end of the sensor contacts the inclined surface of the side wall of the limiting block 9. As the sensor continues to press down, the inclined surface is forced to push the limiting block 9 to move adaptively. At this time, the first spring 11 is compressed and produces elastic deformation. After the sensor is completely inserted into the placement slot 4, the elastic force of the first spring 11 is transmitted to the limiting block 9 through the first connecting plate 10 and the second connecting plate 12, so that the limiting block 9 is always in close contact with the side wall of the sensor, realizing automatic positioning of the sensor without the need for manual adjustment by the operator, effectively avoiding human positioning errors and ensuring welding accuracy.
[0034] When a sensor experiences a welding accident during the welding process (such as poor welding or excessive weld beads) and needs to be removed separately, the operator can insert their finger into the through groove 18 on the side wall of the fixing block 8 and press the upper end of the ejector rod 13 near the sensor. The ejector rod 13 rotates around the mounting shaft 14 as the center, and its inclined part pushes the bottom of the sensor upward. At the same time, the second spring 15 in the connecting mechanism is stretched and produces elastic deformation. As the ejector rod 13 continues to rotate, the sensor is smoothly ejected from the placement groove 4, making it convenient for the operator to quickly remove the faulty sensor for replacement or re-welding.
[0035] After removal, release the ejector rod 13. The elastic restoring force of the second spring 15 pulls the ejector rod 13 back to its initial position through the mounting ring 16, preparing it for the next use. After all sensors have been welded, the operator can slide the two support seats 6 to both sides along the limit rod 5, so that the support seats 6 are removed from under the welding placement plate 2 and no longer support the welding placement plate 2. Then press down on the welding placement plate 2. The vertical rod 7 ensures that the welding placement plate 2 moves down only in the vertical direction. When the welding placement plate 2 moves down a certain distance, the multiple positioning posts 3 at the upper end of the tooling base plate 1 extend into the respective placement slots 4. Continue to press down on the welding placement plate 2. The positioning posts 3 continue to push the sensors in the placement slots 4 upward until the sensors are completely removed from the placement slots 4, realizing the synchronous batch removal of multiple qualified sensors and greatly improving the material handling efficiency after welding.
[0036] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
