Description

Technical Field

[0001] This utility model relates to the field of sensor manufacturing technology, specifically to a sensor adhesive curing fixture. Background Technology

[0002] A sensor is a device that can sense the information being measured. Its main function is to convert various external information (such as physical, chemical, and biological quantities) into electrical signals or other processable forms, thereby enabling the acquisition, transmission, processing, storage, display, and control of information. It plays a crucial role in modern electronic systems, is at the forefront of industrial products, and plays a vital role in perceiving the physical world.

[0003] In sensor manufacturing, adhesive curing is a crucial step. Adhesive curing protects and secures the internal components of the sensor, ensuring its proper functioning in harsh environments and improving its stability and durability. Curing methods include room temperature curing, heat curing, and UV curing. Heat curing significantly shortens curing time and improves production efficiency. Heating accelerates the chemical reactions within the potting compound, allowing it to fully cure in a shorter time, resulting in more stable performance after curing.

Utility Model Content

[0006] The present invention aims to overcome the defects in the prior art and provide a sensor adhesive curing fixture that can position the sensor, ensure that it does not move during the heating and curing process, and apply a stable and controllable pressure to the sensor.

[0007] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a sensor adhesive curing fixture, including a base, wherein the base is provided with a plurality of positioning structures that match the sensor for placing and limiting the horizontal displacement of the sensor; a limiting member corresponding to each of the positioning structures is provided above the base, and the limiting member covers the positioning structure; the base is also provided with a fixing structure for applying a pressing force to the sensor.

Detailed Implementation

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figures 1-6 As shown, a sensor adhesive curing fixture includes a base 1, on which a plurality of positioning structures 101 matching the sensor are provided for placing and limiting the horizontal displacement of the sensor; above the base 1 are limiting members 3 corresponding to the positioning structures 101 one by one, and the limiting members 3 cover the positioning structures 101; the base 1 is also provided with a fixing structure 2 for applying a pressing force to the sensor.

[0030] Furthermore, a plurality of positioning structures 101 are arrayed on the upper surface of the base 1. The sensor is placed in the positioning structure 101, and each positioning structure 101 corresponds to a sensor. The positioning structure 101 achieves horizontal limiting of the sensor, thereby preventing displacement of the sensor during the adhesive curing process. In addition, a limiting member 3 is also covered above the positioning structure 101. With the cooperation of the limiting member 3 and the positioning structure 101, the sensor is doubly limited in the horizontal direction, ensuring that the components of the sensor will not shift during the adhesive curing process, thereby improving the positioning accuracy of each component of the sensor. At the same time, the fixing structure 2 set on the base 1 can apply a stable pressing force to the sensor, increasing the stability of the sensor during the adhesive curing process, ensuring that the components of the sensor are tightly pressed together, thereby improving the quality of the sensor.

[0031] The positioning structure 101 includes a positioning groove 1011 and positioning protrusions 1012. The positioning protrusions 1012 are disposed on the surface of the base 1 and are distributed around the edge of the groove opening of the positioning groove 1011. Furthermore, the positioning groove 1011 is a recess disposed on the upper surface of the base 1, and a plurality of positioning grooves 1011 are arranged in an array on the base 1. This allows the fixture structure to accommodate the simultaneous adhesive curing of multiple sensors, and the shape of the positioning groove 1011 is adapted to the shape of the sensor, allowing the sensor to be placed in the positioning groove 1011. In this process, the horizontal direction of the sensor is restricted by the positioning groove 1011, thereby preventing the sensor from moving during the curing process and affecting the accuracy of the glue after curing. In addition, a corresponding positioning protrusion 1012 is provided at the opening of the positioning groove 1011. The positioning protrusion 1012 surrounds the opening of the positioning groove 1011 and is set on the upper surface of the base 1. The positioning protrusion 1012 protrudes upward on the upper surface of the base 1. The limiting member 3 is connected to the positioning protrusion 1012.

[0032] The limiting member 3 is fastened to the positioning protrusion 1012, and the bottom of the limiting member 3 is provided with a connecting groove 302 that matches the positioning protrusion 1012. Furthermore, the structural shape of the limiting member 3 is the same as that of the positioning protrusion 1012, and its size is larger than that of the positioning protrusion 1012. A connecting groove 302 is provided on the lower surface of the limiting member 3, and the shape of the connecting groove 302 matches the shape of the positioning protrusion 1012. When the limiting member 3 is fastened to the positioning protrusion 1012, the positioning protrusion 1012 is located in the connecting groove 302. Through the cooperation between the positioning protrusion 1012 and the connecting groove 302, the horizontal limitation of the limiting member 3 is achieved.

[0033] The limiting member 3 has a through hole 301 that is connected to the positioning groove 1011. The fixing structure 2 passes through the through hole 301 and abuts against the sensor. Furthermore, the through hole 301 is located in the middle of the limiting member 3. When the limiting member 3 is fastened to the positioning protrusion 1012, the through hole 301 is located directly above the positioning groove 1011, and the shape of the through hole 301 is adapted to the structure of the fixing structure 2. The fixing structure 2 passes through the through hole 301 and abuts against the sensor, thereby applying a pressing force to the sensor.

[0034] The center area of ​​the limiting member 3 is provided with a downwardly extending limiting part 303. The limiting part 303 is arranged around the bottom edge of the through hole 301. Furthermore, the limiting part 303 is arranged on the lower surface of the limiting member 3 and extends downward. The limiting part 303 is arranged around the bottom of the through hole 301. When the limiting member 3 is fastened to the positioning protrusion 1012, the limiting part 303 is inserted into the positioning groove 1011. The bottom end of the limiting part 303 abuts against the piezoelectric ceramic of the sensor. The limiting part 303 restricts the position of the piezoelectric ceramic and prevents the piezoelectric ceramic from moving. The piezoelectric ceramic is a structure inside the sensor. The sensor is mainly composed of a matching layer, a stainless steel sheet and a piezoelectric ceramic, etc. The various components are bonded together with glue.

[0035] An adjustment groove 3011 for adjusting the position of the sensor component is provided on the inner wall of the through hole 301. Furthermore, adjustment grooves 3011 are provided on the inner walls on both sides of the through hole 301. The adjustment grooves 3011 are arranged along the thickness direction of the limiting member 3 and have a semi-circular arc structure. When the limiting part 303 abuts against the piezoelectric ceramic and the posture or position of the piezoelectric ceramic is offset, the piezoelectric ceramic can be moved by a lever or other rod-shaped structure that can pass through the adjustment groove 3011, thereby realizing the adjustment of the position or posture of the piezoelectric ceramic and ensuring the installation positioning accuracy of the piezoelectric ceramic and the sensor during the glue curing process.

[0036] The fixing structure 2 includes several pressure blocks 201. Each pressure block 201 has a pressing part 2011 at its bottom that abuts against the sensor. Furthermore, each pressure block 201 is a rectangular columnar structure. The pressure blocks 201 and several positioning structures 101 are paired to apply a pressing force to the sensor. The pressing part 2011 is located at the bottom center of each pressure block 201, and its structural dimensions are adapted to the through hole 301 of the limiting member 3. The clamping part 2011 passes through the through hole 301 and abuts against the sensor. The weight of the clamping block 201 itself generates a clamping force on the sensor, ensuring that the sensor can be tightly clamped. In addition, when it is necessary to change the magnitude of the clamping force, the magnitude of the clamping force applied to the sensor can be adjusted by replacing the clamping block 201 of different sizes and weights. Since the weight of each clamping block 201 is known, the magnitude of the clamping force applied to the sensor can be precisely adjusted, thereby achieving precise control of the clamping force.

[0037] The fixing structure 2 also includes a support plate 202 for limiting the position of a plurality of pressure blocks 201. The support plate 202 is provided with a plurality of limiting grooves 2021, and the plurality of pressure blocks 201 are located in the limiting grooves 2021. Furthermore, the support plate 202 is provided with a plurality of limiting grooves 2021, and the plurality of pressure blocks 201 are inserted into the corresponding limiting grooves 2021. The spacing between adjacent pressure blocks 201 is the same as the spacing between a plurality of adjacent positioning structures 101, thereby ensuring that each pressure block 201 can accurately enter the positioning groove 1011 of the positioning structure 101. The support plate 202 is used to fix and limit the pressure blocks 201, thereby preventing the pressure blocks 201 from shaking and causing the value of the pressing force applied by the pressure blocks 201 to fluctuate, thus affecting the stability of the applied pressing force.

[0038] The base 1 is provided with several support columns 203 for connecting the support plate 202. The support plate 202 is provided with connecting holes 2022 for connecting the support columns 203. Furthermore, the support plate 202 is suspended above the base 1. The size and structural shape of the support plate 202 are the same as those of the base 1, and the support plate 202 is arranged parallel to the base 1. Several support columns 203 are connected to the corners of the base 1, and several connecting holes 2022 corresponding to the support columns 203 are also provided at the corners of the support plate 202. 22. The support column 203 is a cylindrical rod-shaped structure with external threads. An internal thread that matches the external thread on the support column 203 is provided in the connection hole 2022. The support column 203 and the support plate 202 are connected by threads. Under the action of the threads, the support column 203 at the corner can be rotated to adjust the distance between the support plate 202 and the base 1. In this way, the distance between the pressure block 201 and the positioning structure 101 can be adjusted, so as to meet the pressure of the pressure block 201 with different height dimensions to apply pressure to the sensor.

[0039] The support column 203 penetrates the base 1 and extends downward to form a support portion 2031 for supporting the base 1. The base 1 is provided with mounting holes 102 for mounting the support column 203. Furthermore, mounting holes 102 for connecting the support 203 are provided at the corners of the base 1, and internal threads are also provided in the mounting holes 102. The support column 203 is connected to the base 1 by bolts. The support column 203 penetrates the entire base 1. Specifically, the bottom end of the support column 203 is connected to the support portion 2031. The diameter of the support portion 2031 is larger than the diameter of the main body of the support column 203, that is, the main body refers to the threaded part. The top end of the support column 203 is screwed into the mounting hole 102 from the bottom of the base 1 until the upper end of the support portion 2031 abuts against the lower surface of the base 1. At this time, the support portion 2031 supports the base 1, thereby making the base 1 in an elevated state, which facilitates the handling of the tooling in the heating device.
